BACKGROUND OF THE INVENTION field of invention
The present invention generally relates to structures, including at least one part constructed of plastic, and particularly to furniture, such as tables and chairs, which may include molded plastic components. Description of related art Description of related art
Many different types of tables are well known and used for many different purposes. For example, conventional tables may include legs that are hingedly secured to the table top, with the legs being shiftable between a position of use, in which the legs extend away from the table top, and a position storage, in which the legs are folded against the table top. Conventional tables with relatively large table tops and folding legs are often referred to as "banquet tables" and these tables are often used in boardrooms, banquet halls, convention centers, hotels, colleges, churches, and other venues. where large groups of people gather. Tables of this type can be placed in a variety of different configurations and used in a variety of layouts. When banquet tables are not in use, the table legs can be moved into storage position and tables can be more easily transported and stored.
Because most banquet tables are 1,828 to 3,048 meters long and 20 ,9144 to 1,219 meters wide, the storage area required for such tables is quite large, even with the legs in the folded position. This large storage area can be a problem for businesses or places that use them, such as hotels, schools and churches, due to the large amount of these tables that may need to be stored.
Conventional tables often include table tops constructed of materials such as wood, particleboard or metal. Table tops constructed of wood, chipboard or metal, however, are often relatively heavy and this can make tables awkward or difficult to transport. Table tops constructed of wood or metal are also relatively expensive and these types of table tops generally must be treated or finished before use. For example, table tops constructed of wood generally must be sanded and painted, and metal table tops must be molded into the desired shape and painted. Additionally, these wooden and metal table tops are relatively heavy, which can increase the cost of shipping and transporting the tables. The weight of the table top can make tables more difficult to transport and store.
To lessen the weight of conventional tables, table tops can be constructed of relatively light materials such as plastic. Disadvantageously, these table tops constructed of light weight materials 20 may require reinforcing elements or other structural parts such as frames, clamps, supports and the like to strengthen the table top. While these additional pieces can increase the strength of the table top, the added pieces can also increase the table's weight. These complementary parts can result in higher production costs and require more time to assemble the table. Additionally, extra fasteners may be needed to assemble and connect these parts to the table, which may require more time and labor during the manufacturing process. Additional parts and fasteners 5 can also increase the cost of the table and make the table more difficult to manufacture. Additionally, these parts and additional fasteners may have sharp edges that could injure the user's legs or arms.
Conventional tables can include a frame that is attached to the table top. The frame can include a pair of side rails that are attached to the sides of the table top using fasteners. Various fasteners may be required to securely attach the frame to the tabletop and transmit forces applied from the tabletop to the frame. Undesirably, when a large load or force is applied to some known tables, the frame may bend, deform or become disconnected from the table top. In addition, the fasteners used to attach the frame to the table top may come loose or separate from the table top. The fasteners can further damage and tear the table top if this load or force is excessive. Also, the frames or fasteners on some known tables may break under some circumstances.
The table tops of some known tables may undesirably bend or deform if a relatively large load or force is applied to a portion of the table top. For example, if a load or force is applied to an outer portion of a conventional table top, this portion of the table top may undesirably move or bend. In particular, this portion of the table top may flex downward when a load or force is applied to the upper surface of the table top.
The large size of conventional banquet tables may require manufacturers, traders and consumers a great deal of storage space. This large amount of storage space can be a problem, especially for manufacturers, traders and consumers who need to store, transport and/or display a large number of tables. BRIEF SUMMARY
Therefore, there is a need for a table that reduces or eliminates the disadvantages and problems described above.
One aspect is a table that can include a table top and one or more legs sized and configured to support the table top on a surface, such as the floor or floor. The table can also include a frame and the legs can be attached to the frame. The legs can be moved relative to the table top between a stowed or storage position and an extended or use position. In particular, the legs can be hinged between a retracted position, in which the legs are arranged at least in proximity to a lower surface of the table top and an extended position, in which the legs extend outside the table top . If desired, the legs may at least partially touch or touch the lower surface of the table top when the legs are in the stowed position. In addition, the lower surface of the table top may include one or more recesses sized and configured to receive at least a portion of the legs when the legs are in the stowed position. Advantageously, this can reduce the amount of space needed to store and/or transport the table.
Another aspect is a table that can be relatively light, allowing the table to be more easily transported and moved. For example, the table can include a light table top that can reduce the total weight of the table. The table can also be constructed with a limited number of parts or components, which can allow the table's weight to be reduced. In addition, a limited number of fasteners may be required to mount the table, which can also reduce the table's weight. The limited number of fastening elements can also allow the table to be assembled more quickly and easily.
Yet another aspect is a table that can include a table top constructed of plastic. For example, the table top can be constructed of molded plastic using blow molding, injection molding, rotary molding or other suitable molding processes. The molded plastic table top can provide a relatively rigid, high strength frame 5 that is capable of withstanding repeated use and wear. The molded plastic table top can also be manufactured relatively quickly, easily and efficiently. In addition, the molded plastic table top can be easily molded to the desired dimensions and shapes, such as for a utility table, game table, personal table and the like. The molded plastic table top can be relatively lightweight since, for example, it can include a hollow inner portion formed during the molding process. The molded plastic table top can further include two opposing walls which can be spaced apart by a generally constant and/or predetermined distance, and which can help to increase the strength and rigidity of the table top. 20 molded plastic table top can be generally weather resistant and temperature insensitive. In addition, molded plastic table tops will not rust, corrode, or deteriorate for an extended period of time, which can help create a long-lasting table.
Yet another aspect is a table that can be constructed of molded plastic and one or more features can be integrally formed during the molding process as part of a unit, constructed in one piece. For example, the molded plastic table top can include one or more dips (also known as "tack-offs") and the dips can be designed to increase the strength of the table top and/or interconnect the spaced walls. The depressions can also be sized and configured to create a frame with particular characteristics and qualities, such as a tabletop with strength, uniform stiffness and/or structural integrity. The molded plastic table top can also include other features, such as structures that increase the strength, rigidity and/or torsional strength of at least a portion of the table top.
Yet another aspect is a table that can include components that can be manufactured quickly and easily. For example, the legs and/or spars of the frame can be relatively easy to manufacture. In addition, the frame legs and/or spars can be quickly and easily attached to the table, which can reduce manufacturing costs. The table can also be constructed in a few pieces and a limited amount of fasteners may be required, which can allow the table to be quickly and easily assembled by the manufacturer, trader and/or consumer.
Another aspect is a table that can facilitate the stacking of a plurality of tables. Advantageously, the stacked tables can be arranged in an alignment configuration. For example, a table can be easily aligned with an adjacent table, which can facilitate the transport, storage and/or display of multiple tables. Significantly, the in-line tables can be arranged vertically, horizontally, or at suitable angles depending, for example, on whether the tables will be transported, stored or displayed. If desired, stacked tables can block or have a tendency to stick together. For example, an interference or friction fit between adjacent stacked tables tends to keep the tables in a stacked configuration. If tables are prone to sticking together, this can help reduce damage to tables during transport, storage and/or display.
Yet another aspect is a table that can be docked with an adjacent table to reduce space. Significantly, push-in tables can allow tables to be stored in a smaller area, which can substantially reduce transport and storage costs. Dockable tables can also allow more tables to be stored in the same area as conventional tables that do not fit together. In addition, the dockable tables help to protect the tables from damage. For example, because an upper portion of a table can be disposed within a lower portion of an adjacent table, which can help prevent table damage. Plug-in tables can also have table tops the same size or substantially the same size as conventional tables, which may indicate that the tables have similar appearance and characteristics, such as strength, structural integrity, among others. Dockable tables can also be generally the same size as a conventional table, but dockable tables significantly allow more tables to be arranged on a forklift or shipping container and/or allow the same number of tables to be arranged on a significantly smaller space.
Yet another aspect is a table that can be docked with an adjacent table in a stacked configuration. Advantageously, the pluggable tables have a significantly reduced height compared to conventional tables that do not fit together. For example, known tables may have a table top with a height of about 2.125 inches (5.39 cm), so thirty of these conventional stacked tables would have a height of at least 63.75 inches (1.62 m). ). An exemplary embodiment of an embedded table may have a table top about 2.0 inches (5.0 cm) thick, but may overlap an adjacent table by about 0.25 inches (0.63 cm) ), so the height of the docked table can only be about 1.7 5 inches (4.45 cm) when docked with another table. Thus, the height of thirty nested tables can only be about 52.75 inches (1.34 m) because adjacent tables can snap together. In particular, because a portion of a table may be disposed within or overlapping an adjacent table in the nested configuration, this may allow the overall height of the nestable tables to be decreased. Therefore, in this exemplary configuration, the table height in the docked configuration may only be about 1.75 inches (4.45 cm). Consequently, push-in tables have a height reduction of between 0.375 and 0.25 inches (0.95 and 0.63 cm) per stacked table compared to previously known tables. This can allow more tables to be arranged in a stacked configuration, which can significantly increase the number of tables that can be stacked on a bench or shelf, or arranged in a container or truck.
Yet another aspect is a table that can be docked together with an adjacent table to reduce the overall height of the stacked tables. For example, a conventional table may have a blow molded table top having a height of approximately 2.0 inches (5.0 cm) and a frame having a height of about (1.625) inches (4.13 cm). The height of the frame for this type of conventional table is more than eighty percent (80%) of the height of the table top to create a table with the required strength and rigidity. The frame for this type of conventional table can have a rectangular transverse configuration, which can help to create a beam-like frame with two opposing walls that are separated by a generally constant distance. It is known that a decrease in frame height can result in a decrease in table strength. It is also known that a decrease in frame width can allow undesirable twisting or bending to occur in the table. In contrast to these familiar tables, plug-in tables are generally the same height and appearance as a conventional table and generally the same strength and structural integrity as a conventional table, but the tables can fit together. The similar size and dimension of the tables can allow consumers to immediately deduce that the pluggable tables have generally the same strength, rigidity, resistance to twisting as conventional tables. Dockable tables, however, significantly decrease the height of two or more stacked tables. Because push-in tables can have a significant decrease in height in the push-in configuration, this can result in considerable space savings, which can be very important to the manufacturer during the manufacturing and shipping process; for the merchant, regarding the storage or display of several tables; and/or for the consumer to buy, transport or store more than one table.
Another aspect is a table that can be sized and configured to be docked so that the height of the dockable tables is reduced by more than ten percent (10%) . For example, the height of a single table might be about 2.0 inches (5.08 cm). When the table is docked with another table, the height of the table can be about 1.75 inches (4.45 cm) because one part of the table is docked with the other. In this modality, the push-in tables result in a decrease in the height of each stacked table of about 0.25 inch (0.63 cm). Therefore, the height of a table in the stacked configuration can be approximately twelve and a half percent (12.5%) less than in the non-stacked configuration. Advantageously, this can allow tables to be efficiently stored, transported and displayed, as less space may be required. In another example, a standard pallet or shipping configuration may include twenty-one (21) conventional tables, but tables with these snapping features disclosed herein may allow twenty-seven (27) or twenty-nine (29) to be placed in a standard pallet or in a typical shipping configuration. If twenty-seven tables are placed on a pallet or in a standard shipping configuration, rather than twenty-one tables, then about twenty-eight percent (28%) more tables can be stored, shipped, or displayed. If twenty-nine tables instead of twenty-one tables are placed on a pallet or in a standard shipping configuration, a thirty-eight percent (38%) increase in table numbers can be achieved.
Advantageously, this can result in significant savings and cost advantages, because, for example, considerably more tables can be stored, transported or displayed in the same area; or the same number of tables can be stored, transported or displayed in an area that is at least twenty-five percent (25%) smaller. When large volumes of tables are transported, such as in a standard or high-capacity shipping container, this can result in advantages and savings.
A further aspect is a table that can be docked with an adjacent table such that the height of a nestled table is reduced by approximately twenty percent (20%). For example, the height of a conventional blow molded plastic table top is typically 2.0 inches (5.08 cm) or more. The table top height of a docked table can be about 2.0 inches (5.0 cm) when it is not docked with another table, but the height of the table can only be between about 1.5 and 1 .75 inches (3.81 and 4.45 cm) when docked with another table. This can result in a significant reduction in height between twelve and a half percent (12.5%) and twenty-five percent (25%) when two or more tables are locked together. In particular, if the push-in desks are lowered in height by approximately twenty percent (20%), then the desks can have a height of about 1.6 inches (4 cm) in the push-in configuration. Additionally, the embedded table has a weight that is less than the weight of conventional tables. The nested table, therefore, can contribute less weight when stacked or nested with one or more tables and this can allow a greater number of nested tables to be stacked without additional weight.
Yet another aspect is a table that may include a receiving portion, such as a groove, channel, or a recessed portion in an upper portion of the table top sized and configured to receive a portion of a portion of an adjacent table to facilitate snapping-in. of the tables. For example, the receiving portion may be disposed on an upper surface and/or outer perimeter of the table top. In greater detail, the receiving portion may have a generally L-shaped configuration, with a lower surface generally parallel to the upper surface of the table top and a side wall generally perpendicular to the upper surface of the table top. A portion of an adjacent table may be disposed on the receiving portion to allow tables to be fitted together. In particular, a portion of the frame, such as a projection or flange and/or a portion of the table top, such as an edge or a corner, may be disposed on the receiving portion. In greater detail, a portion of the side walls of the frame may be disposed in the receiving portion along the sides of an adjacent, stacked table. A lower portion of an edge and/or corners of the table top may also be disposed on the receiving portion of the adjacent, stacked table.
Yet another aspect is a table that can include a frame sized and configured to facilitate stacking of tables. For example, the frame may include an upper portion generally aligned with the lower portion of the table top. The upper portion of the frame can be disposed in a frame of the receiving portion on the lower portion of the table top and this can help to keep the frame in the desired position. The frame may also include a smaller portion sized and configured to contact an upper portion of an adjacent stacked table. The frame may further include a coupling portion sized and configured to be disposed on the receiving portion of an adjacent pluggable table. The coupling portion may include a downwardly extending projection or flange sized and configured to fit within the receiving portion, such as a groove or notch of the adjacent snap-on table. Advantageously, the frame can directly support at least a portion of the weight and/or force applied to the tables in the nested configuration, which can help prevent damage to the tables. For example, when tables are stacked in a horizontal configuration, a table frame can contact the adjacent table in a way that allows the stacked tables to support a significant amount of weight without causing damage to the tables. This can allow ten, twenty, thirty or more tables to be arranged in a stacked configuration without damaging any of the tables. In addition, the coupling portion of the frame is disposed in a receiving portion of an adjacent table, which can facilitate the stacking, storage and/or transport of the tables, as it can help to keep the tables in the stacked configuration and ensure that the weight is correctly and/or evenly distributed.
Yet another aspect is a table that can be sized and configured to fit with an adjacent stacked table, where a load or weight is supported on several different areas, locations and/or surfaces. Advantageously, the multiple contact areas can allow stresses and forces to be spread over a larger area and can help prevent damage to the tables. For example, the table may include one or more contact areas sized and configured to contact the upper surface of the adjacent table top. In more detail, the side rails of the frame may include a lower portion, such as a flat contact surface or load-bearing surfaces, arranged generally parallel to an upper surface of the table top. In addition, the side rails of the frame may include a coupling portion, such as a downwardly extending projection or flange, sized and configured to be disposed on a receiving portion of the adjacent stacked table. The lower portion of the flange may contact a lower surface of the receiving portion, which may be another load-bearing surface. In addition, the table may include other portions such as corners or edges sized and configured to be disposed on the receiving portion of the adjacent stacked table. For example, the corners and/or edges may include a pressing edge which contacts the lower surface of the receiving portion, which may also be load bearing surfaces. When two or more tables are nested together, the multiple contact areas can facilitate table stacking without damaging or damaging the tables.
Another aspect is a table which can include a table with one or more formed portions of compression molded plastic. For example, a portion of the corners and/or edges may be compression molded during the blow molding process. Advantageously, the compression molded corners and/or edges can help create stronger, stiffer and/or more impact resistant structures, which can increase the durability and usability of the table. Significantly, compression molding can allow a portion of the corners and/or edges to be relatively thin because there is little or no gap or space between the walls of the compression molded plastic structure. The compression molded corners and/or edges can also be sized and configured to fit within a receiving portion of an adjacent stacked table, which can facilitate the stacking and nesting of the tables. The compression molded portions can also be sized and configured to contact a portion of the frame. For example, a compression molded portion may be disposed along at least a portion of the edge and side rail of the frame may contact or abut the compression molded portion, which can help position and hold the frame in position. desired.
Yet another aspect is a table that can include a compression edge. For example, if the table top is constructed of blow molded plastic, the pressing edge may be formed by the outer wall being folded back on itself so that the pressing edge has a thickness of approximately twice the thickness of the outer wall. The pressing edge can be arranged over all or part of the perimeter of the table top, such as the edges or corners. Advantageously, the compression edge can help provide greater strength, rigidity, structural integrity and/or impact resistance. The pressing edge may also be dimensioned and configured to at least partially dispose the receiving portion of an adjacent plug-in table.
Yet another aspect is a table that can include a different sized compression edge. For example, the table top corners may include a pressing edge that is a different size than the pressing edge that extends along the sides and/or ends of the table top. Particularly, the table top may include a downwardly extending edge and the corners may include a pressing edge that is generally equal to or greater than the majority of the edge's height. The corners can also include a pressing edge having a height generally or at least substantially equal to the height of the edge. The sides of the table top may include a pinch edge smaller than the pinch edge at the corners. For example, the sides of the table top can include a pressing edge having a height that is generally equal to or less than the height of the edge. The height of the pressing edge disposed along the sides and/or edges of the table top can also be significantly less than the height of the edge. In an exemplary embodiment, the compression edge disposed on the sides of the table top can be between 0.125 inches (0.32 cm) and about 0.25 inches (0.63 cm) in height, and the corners can include an edge of compression with a height between 0.25 inch (0.63 cm) and about 0.5 inch (1.27 cm). The pressing edge along edges of the table top can have a height between 0.125 inch (0.32 cm) and about 0.5 inch (1.27 cm). Thus, the pressing edge of the corners and/or ends of the table top can be two or more times larger than the pressing edge along the sides. Corner compression edges can be much larger if desired, such as three, four, five or more times the edge compression height along the sides and/or edges.
Yet another aspect is a table that may include a handle disposed at one or both ends of the table top. The handle may consist of a recess or opening in the edge that extends down from a table top and the handle may be integrally formed with the table top as part of a unit constructed in one piece. Preferably, the handle is sized and configured to facilitate table movement and transport. In addition, the handle can help separate tables when they are in a stacked configuration. The table top may further include recesses or openings which may allow a portion of the frame to be disposed on the sides of the table top. For example, the sides of the table top can include openings that allow at least a portion of the frame to be exposed. Therefore, the ends of the table may include openings in the edge that form the handles and openings in the sides that allow a portion of the frame to be exposed. Other portions of the frame can be inserted and/or disposed internally on an outer perimeter of the table top, which can help protect the frame from damage.
Another aspect is a table that may include a frame with a first portion disposed along one side of the table top and a second portion disposed along a second side of the table top. In particular, the frame may include a first side rail disposed along a first side of the table top and a second side rail disposed along a second side of the table top. The side rails can extend the length and/or width of the table top and the side rails can help support the table top and/or facilitate the connection of the legs to the table top. Each side rail can include a body, and the body can be elongated to have one or more mating surfaces and can be constructed of relatively strong materials such as metal. In more detail, the body of the side rails can be arranged at least close to an edge extending from the table top and the body of the side rails can be disposed vertically with respect to the table top. The side rails can also include an upper portion and a lower portion. For example, the top portion of the side rail may include a flange that extends internally at an angle, such as a right angle to the body. The upper portion of the side rail may also include a second flange, such as an inner flange that may extend downwards. This inner flange may be arranged at least close to the end of the upper portion of the side rail and may be arranged generally parallel to the body of the side rail. The lower portion of the side rail may include a flange that extends outwardly to an outer portion of the table top. The lower portion may also include a downwardly extending portion, such as a flange or projection, which may be disposed perpendicular to the lower portion of the side rail. If desired, the downwardly extending portion can be twice as thick as other portions of the frame. In particular, the downwardly extending portion may be bent or curved upon itself and includes an upwardly extending portion sized and configured to contact a portion of the table top, such as a lower surface of the extending edge. down.
Yet another aspect is a table that may include a table top with one or more receiving portions sized and configured to receive a portion of the frame. For example, the table top may include a frame receiving portion sized and configured to receive an upper portion of the frame side rail. In addition, the table top may include a side wall sized and configured to contact the body of the side rail and an edge sized and configured to contact the lower portion of the side rail. If desired, an inner edge wall may form at least a portion of the side wall and a lower edge portion may contact the lower frame portion. Advantageously, the table top can be sized and configured to help position and/or maintain the side rail in the desired position. In addition, the table top can be sized and configured to help prevent the side rail from bending, twisting or moving, helping to create a stronger, stronger table.
Yet another aspect is a table that can include a frame having one or more generally L- or U-shaped sections. For example, the side rails of the frame can include an upper portion having a generally U-shaped configuration. inverted and a lower portion with a generally U-shaped configuration. The upper portion of the frame can be sized and configured to be disposed in a receiving portion of the frame in a lower or lower portion of the table top. The lower portion of the frame can be sized and configured to contact an adjacent table in a stacked nested configuration.
In particular, the lower portion of the frame may include a lower surface sized and configured to contact an adjacent upper surface of the table in the nested configuration. The lower portion of the frame may further include a coupling portion sized and configured on a receiving portion of an adjacent table in the nested configuration.
Yet another aspect is a table that can include a frame that facilitates nesting and stacking a plurality of tables. The frame can also help support an edge that extends below the tabletop. For example, the frame may support an inner surface, the lower surface and/or the outer edge portion. In addition, the frame can provide multiple contact areas, such as a flat mating surface and a mating portion or flange, which can allow a load to be distributed over multiple areas when multiple tables are fitted together. This can allow more tables to be arranged in a stacked configuration and/or help prevent damage to the tables.
Another aspect is a table that may include a frame with an internally disposed portion and an externally disposed portion. For example, the frame may include a first portion disposed towards an inner portion of the table top, and a second portion disposed towards an outer portion of the table top. The internally disposed portion may be at least partially or substantially internally disposed on an edge extending below the table top, while the externally disposed portion may contact and/or close at least a portion of the edge.
Yet another aspect is a table that can include a frame and a portion of the frame can be disposed along an edge or a perimeter of the table top. For example, the table top may include an edge with an opening and an outer portion of the frame may be disposed in or at least close to the opening. Advantageously, this can allow a portion of the frame to be exposed, and the exposed portion of the frame can indicate to consumers that the table has great strength, is strong and durable. The exposed portion 15 of the frame may be generally aligned and/or spaced inwardly from an outer perimeter of the table top. The exposed portion of the frame may also be generally aligned with a lower portion of the table, such as a lower surface of corners, edges and/or edges. In more detail, an opening can be arranged at the edge along the sides of the table top and the exposed portion of the frame can be arranged and/or generally aligned with the openings. The lower portion of the frame may be aligned with a lower portion of the table top 25 or this could extend outwardly more than configuration, the lower portion of the frame may form the lower portion of the table top. The exposed frame can also create a table with better aesthetics and/or style. For example, the exposed frame can provide a color contrast with the table top. That is, the table top can be one or more colors and the frame can be one or more different colors to create a table with a stylized look or an aesthetically pleasing design.
Yet another additional aspect is a table that may include a table top with openings to allow a portion of the frame to be exposed and/or disposed near a perimeter of the table top. For example, the table top may include one or more openings that allow at least a portion of the frame to be exposed and disposed at least near the perimeter of the table top. These openings can extend at least along most of the length of the table top. The table top may also include one or more openings for a handle at the ends of the table top. The openings in the sides of the table top are preferably much larger than the openings in the ends of the table top, by a factor such as five, ten, twenty or more times the length of the opening for the handle.
Yet another aspect is a table that may include a frame that contacts, couples and/or supports an edge and/or outer perimeter of the table top. Advantageously, if the frame is disposed along the outer edges of the table top, then the frame can provide greater support for the edges or ends of the table top. Furthermore, if a portion of the frame is disposed below or close to the edge, then the frame can help prevent the table top from being damaged. For example, the frame can absorb impacts or forces, which could otherwise damage the table top.
Yet another additional aspect is a table which may include a frame with a coupling portion, such as a protrusion or flange, which facilitates the engagement and stacking of the tables. The bulge may generally be aligned and/or disposed close to the underside of the edge, such as a pressing edge. Because the compression and protrusion edge can have double wall thicknesses, this can help prevent the table from being damaged. In more detail, the protrusion can be bent or curved about itself so that it includes two parallel and adjacent walls and a rounded end. The pressing edge can include an inner wall and an outer wall that are parallel and adjacent, preferably contacting each other. If desired, the pressing and protruding edge can include undersurfaces that are generally aligned and arranged in the same plane. Advantageously, the double wall thicknesses of the frame and edge can help prevent the table top from being damaged. In addition, double wall thicknesses can promote stacking and nesting of tables because, for example, it can allow a strong, thin, resilient and/or damage-resistant portion of a table to be disposed in the receiving portion of a table. adjacent.
Another aspect is a frame for a table that may be less likely to bend or deform in an undesirable way. For example, the frame can have a configuration that resists twisting or rotation when load or force is applied to the frame. Additionally, the frame can provide more balance on the table when a load or force is applied. For example, the frame could include a number of curves or angles, such as a plurality of 90° or straight angles. Advantageously, the various angles can help increase frame strength, resistance to twisting or rotation when load or force is applied to the frame, and/or provide more balance. The frame could also include one or more portions that are bent or curved about themselves at an angle of 180° so that the portions of the frame are twice as thick. This can also help to increase frame strength, resistance to twisting or rotation when load or force is applied to the frame and/or provide more balance.
Yet another aspect is a table that may include a frame at least partially disposed in one or more receiving portions on the table top. The table top may also include one or more receiving portions that are sized or configured to receive other table components such as cross members, cross bars and the like. For example, the table top may include receiving portions sized and configured to receive an upper portion of a support structure. The table top may also include receiving portions sized and configured for the receiving portion of the legs when the legs are in the stowed position. In addition, the frame may include one or more openings that are sized and configured to facilitate securing the legs to the table. For example, the frame may include openings that are dimensioned and configured to receive the ends of a cross member and/or the upper portion of a support structure. Depending on the shape and arrangement of the frame, the openings in the frame can have circular or non-circular configurations. The legs can be securely attached to the table top by extending the ends of the cross tube through the holes in the frame.
Yet another aspect is a table that can include a frame and a set of legs that are constructed of relatively strong and durable materials, such as metal, steel, and the like. It will be appreciated, however, that the frame and leg assembly may be constructed of other materials with suitable characteristics and properties.
In addition, the table, frame, leg set and the like may thus have a variety of other suitable shapes, sizes, configurations and arrangements depending on, for example, the intended use of the table.
Another aspect is a table that can include a plurality of tables with depressions. The plurality of depressions can be spaced apart and cover at least most, substantially all, practically all or all of the table top bottom surface. The plurality of 10 depressions can be arranged in a generally uniform pattern, where the depressions are generally the same size, shape, orientation and arrangement. Furthermore, at least most of the depressions in the plurality of depressions can be spaced apart from one or more adjacent depressions by a generally consistent or uniform distance. Advantageously, dips can help create a tabletop with greater strength, rigidity and/or structural integrity. Furthermore, if the depressions of the plurality of depressions are generally evenly spaced and arranged in a generally uniform pattern, this can help to create a table top with generally uniform characteristics.
Yet another aspect is a table top which may include reinforcing elements, such as depressions, flutes, grooves and the like, disposed close to or adjacent to structural support elements or table features. For example, the table top may include a plurality of structural elements disposed close to and/or adjacent to the frame. In more detail, the table top may include one or more frame-receiving portions sized and configured to receive the side rails of the frame, and the frame-receiving portion can include a plurality of reinforcing elements. When the frame is attached to the table top portion, the frame may comprise all or a portion of the reinforcing elements in the receiving portion of the frame. The reinforcement elements in the receiving portion of the frame can be arranged in different arrangements and/or configurations and can be used to create areas of increased strength and/or different characteristics. For example, the reinforcing elements can be arranged in first and second configurations. In particular, the first configuration of the reinforcement elements may generally be aligned in the first direction, such as along the table top, while the second configuration of the reinforcement elements may generally be aligned in a second direction, such as across the width of the table top. The first configuration of the reinforcement elements may provide more force in one direction or location and the second configuration of the reinforcement elements may provide more force in a second direction or location. Because the reinforcing elements provide additional strength in different directions and/or locations, this can allow relatively strong, strong, hard or rigid structures to be built.
The other aspect is a table top that can include reinforcing elements with different configurations and/or arranged in different locations, to avoid or minimize potential points of weakness, stress concentration and so on. For example, the reinforcing elements can be sized and configured to support areas of the table top arranged outside the frame. The reinforcing elements can also be sized and configured to help prevent the table top from bending, flexing or closing when a load or force is applied to the portion of the table top. Additionally, the reinforcing elements can be sized and configured to help prevent the table top from twisting or rotating relative to the frame. Advantageously, because the reinforcing elements can help to support the portions of the table top disposed on the frame and/or edges; a strong, sturdy and well-supported table can be created. This can make stacking and nesting tables even easier, because, for example, the lowest tables in the table stack can be susceptible to damage from the weight of the stacked tables.
Yet another aspect is a portion of the table top that may include one or more reinforcing elements disposed between and/or attached to a receiving portion of the frame and an outer portion of the table, such as an edge. In particular, one or more reinforcing elements may connect to a receiving portion of the frame and an edge portion, such as an inner or side edge wall. In more detail, one or more reinforcing elements may be disposed at least partially on the upper surface and/or sidewalls of the frame-receiving portion and on at least a portion of an edge sidewall. Because the reinforcement elements can connect the receiving portion of the frame and the edge, the reinforcement elements can increase the strength and/or structural integrity of the receiving portion of the frame and/or edge. Furthermore, because the frame can cover at least a part of the frame-receiving portion and the edge sidewall, these reinforcing elements can generally be hidden.
Yet another aspect is a table top that can include a plurality of reinforcing elements that are generally aligned. For example, the reinforcement elements may include a body that is generally aligned with an axis and each reinforcement element of the plurality of reinforcement elements may be generally aligned along the same or parallel axes. Advantageously, because the reinforcement elements are generally aligned with an axis, they can increase strength, structural integrity and/or other characteristics in a certain direction, such as along the axis. Aligning reinforcement elements along the same or parallel axes helps to create a tabletop with generally uniform characteristics and properties. The table top may also include another plurality of reinforcing elements that are generally aligned along a different axis. For example, reinforcement elements disposed along the different axis can provide greater strength, structural integrity and/or other characteristics along this axis. Therefore, reinforcing elements arranged along different axes can be used to create portions of the table top with different characteristics. This can allow, for example, that some of the reinforcing elements in the receiving portion of the frame are arranged along a first axis, such as generally aligned with a length of the table, and other reinforcing elements arranged in a second axis, such as aligned. with a table top width. If desired, one or more of the reinforcing elements can be sized and configured to help support the outer or side edges of the table top. For example, reinforcing elements can help prevent the outer edges of the table top from resting directly on the frame, thereby preventing them from unintentionally bending, twisting or flexing. may include reinforcing elements such as ribs disposed on an outer edge or on the edge of the table top. For example, the table top may include an edge or edge and a plurality of reinforcing elements may be formed on the edge. In particular, the inner surface of the edge such as a sidewall may include a plurality of internally extending structural elements. Furthermore, these reinforcing elements can be arranged at least partially on a receiving portion of the frame. Significantly, the reinforcing elements can provide greater strength, strength, rigidity and/or structural integrity to the table top portions, such as the table top portions disposed over the frame and the table top portions that extend beyond of the frame, such as the edge. Advantageously, the reinforcing elements can also help to prevent unwanted bending, twisting or bending of the table top.
Yet another aspect is a table that can include reinforcement elements and depressions in different shapes, sizes, arrangements, orientations and/or configurations. For example, most or substantially all of the center portion of the table top may include generally uniform depressions in shapes, sizes, arrangements, orientations and configurations. This can help create a table top with generally constant features. The side or edges of the table top, however, can include depressions or reinforcement elements in different shapes, sizes, arrangements, orientations and/or configurations. For example, table top edges may include a first group of depressions generally aligned in a first direction and a second group of depressions generally aligned in a second direction. If desired, the first direction can generally be perpendicular, or at an angle of about 30°, 45° or 60° with respect to the second direction. Because depressions or reinforcement elements can be aligned in different directions, the table top portions can have different characteristics. The reinforcing elements close to the edges of the table top can also have different configurations. For example, a first group of reinforcement elements can be arranged in the receiving portion of the frame and a second group of reinforcement elements can be disposed in at least one receiving portion of the frame and the edge. These reinforcing elements may support the portion of the table top disposed above the frame and/or the portion of the table top that extends beyond the frame.
Yet another aspect is a table top that may include a receiving portion on an upper portion of the table top sized and configured to receive a mating portion of an adjacent table in a nested configuration. The receiving portion can be supported by the reinforcing elements in the lower portion of the table top.
For example, the reinforcing elements may extend inwardly to the edge along the sides of the table top and/or be disposed on the lower surface of the table top. An inner portion of the reinforcing elements may contact, engage or abut an inner portion of the receiving portion to provide added strength, support, rigidity and/or structural integrity to the receiving portion. Advantageously, this can allow several tables to be stacked together because the receiving portion can support a much greater amount of weight and strength from the nested tables.
Yet another aspect is a table top which may include a generally uniform pattern of depressions arranged in a plurality of generally aligned lines 15 extending across a lower surface of the table top. The table top may also include a plurality of grooves in the lower surface that are aligned with the lines of the depressions. The lower surface of the table top may also include a recess dimensioned and configured to receive a structural support element such as a crossbar. The channels can be arranged on both sides of the structural support elements and the ends of the channels can be arranged to one side or to the end of the table top. Furthermore, a plurality of depressions can be disposed in a lower portion of the channels. Gutters and depressions can be sized and configured to provide extra strength, rigidity, structural integrity, and/or torsional strength near structural support elements and/or tabletop edges. In more detail, the gutters can be aligned with the lines of depressions and the gutters can have different lengths. The width of the grooves can generally be equal to the width of the depressions in the lower surface of the table top. The trough depressions can generally have the same shape, configuration and arrangement as the standard bottom surface depressions, but with a smaller size. The troughs in the troughs can generally be arranged in the same pattern, arrangement and spacing as the depressions in the bottom surface, which can provide minimal or no interruption to the support of the top surface of the tabletop. This can allow the table top to have generally uniform characteristics such as strength, rigidity, structural integrity and/or torsional strength.
Yet another aspect is a table that may include a combination of features, features, and the like, such as one or more of those discussed above. For example, the table may include a frame with slotting portions that are sized and configured to be disposed on a receiving portion of an adjacent table when the tables are slotted together. The table may also include one or more pressing edges sized and configured to be disposed on the receiving portion of the adjacent plug-in table. Thus, the frames and compression edges can facilitate the alignment and nesting of tables in a stacked configuration. In addition, the table may include depressions or structural elements disposed adjacent to or near portions of the frame, such as the side rails, and these structures may be sized and configured to increase the strength, rigidity and/or structural integrity of the table top portion. table arranged above and/or close to the frame, and/or the portions of the table top that are not directly supported by the frame. In addition, the table may include depressions and/or structural elements disposed angularly with respect to the lower surface of the table top. For example, the table may include edge structural elements disposed perpendicular to the lower surface of the table top. In addition, the table may include openings or recesses in the sides that allow a portion of the frame to be exposed and easily visible when the table is being used or stored, and openings at the ends create the handles.
Another aspect is a table that can be constructed from one or more materials and processes. For example, the table top can be constructed of molded plastic, such as blow molded plastic. The frame and legs can be constructed from high strength materials such as steel. In particular, the frame and/or legs can be constructed of high strength low alloy steel (HSLA) instead of traditional carbon steel. Importantly, 5 HSLA steel can be twenty to thirty percent (20% to 30%) lighter than carbon steel with the same strength. Therefore, a frame constructed with HSLA steel can be lightweight and have the same strength as a conventional table constructed with a carbon steel frame because a smaller 10 gauge HSLA steel can be used. For example, sixteen or eighteen 18 gauge HSLA steel can be used to build the table, which is less than what you would use with traditional steel. HSLA steel, however, has not previously been used in this or other related industries because it is much more expensive than traditional steel. HSLA steel is cost prohibitive. Reducing the amount of steel required to manufacture a table with one or more of the characteristics disclosed here, however, may be more than enough to offset or justify the price of more expensive HSLA steel.
Particularly, because the amount of steel required to create the table with the features disclosed herein may be significantly less than the amount of steel required to create a traditional matching table, HSLA steel may no longer be cost prohibitive. Thus, because less steel is required and/or HSLA steel may be stronger and lighter, the table can be manufactured from HSLA steel.
Yet another aspect is a table that can include legs with support elements that are widely spaced, which can help create a sturdy table that is likely to move or wobble if not desired. The table can also include a table top in various shapes, sizes, configurations and arrangements, such as rectangular, square, circular, rectangular, and the like. In addition, the table top may include one or more openings to allow, for example, a portion of the frame to be exposed and/or to create a handle or handle.
Another aspect is a table which may include a molded plastic table having an upper portion, a lower portion, a hollow inner portion disposed between the upper portion and the lower portion. The upper portion, the lower portion, the hollow inner portion and the lip can be integrally formed as part of a unit, constructed in one piece. The table may also include a side rail of a frame connected to the lower portion of the table top and an upper portion of the side rail may contact the lower portion of the table top. A plurality of depressions may be disposed between the upper portion of the side rail and the upper portion of the table top and the plurality of depressions may be integrally formed in the lower portion of the table top during the molding process as part of a built-in unit. in one piece. The table may also include first and second support structures attached to the table top.
The plurality of depressions may be disposed between a first side of the upper surface portion of the side rail and a second side of the upper surface of the side rail. In addition, each depression of the plurality of depressions may have a first end disposed adjacent the top surface of the side rail and a second end disposed at least proximate the top surface of the table top. The plurality of depressions can be sandwiched between the upper portion of the frame side rail and an upper surface of the table top. Advantageously, the plurality of depressions can be sized and configured to support the portion of the table top disposed above the upper portion of the side rail of the frame. Furthermore, the plurality of depressions disposed between the side rail and top surface of the table top can be sized and configured to create a table top with more uniform characteristics. If desired, the plurality of depressions may be arranged in a generally uniform pattern, each depression in the plurality of depressions may be generally of the same size, shape, configuration and arrangement, and each depression in the plurality of depressions may be spaced apart from an adjacent depression. by a generally constant distance. A second plurality of depressions may also be disposed in a second portion of the table top. The second plurality of depressions may be arranged in a generally uniform pattern, each depression of the second plurality of depressions may generally have the same size, shape, configuration and arrangement, and each depression of the second plurality of depressions may be spaced one apart. adjacent depression for a generally constant distance. In addition, the plurality of depressions may be disposed between a first side of the side rail top surface and a second side of the side rail top surface and the plurality of depressions may be arranged in a generally uniform pattern with each depression of the plurality. of depressions, generally having the same size, shape, configuration and arrangement. Each depression of the plurality of depressions may be spaced apart from an adjacent depression by a generally constant distance.
Yet another aspect is a table which may include a molded plastic table top having an upper surface, a lower surface and a hollow inner portion disposed between the upper surface and the lower surface. The top surface, bottom surface and hollow inner portion can be integrally formed during the molding process as part of a unit, constructed in one piece. A receiving portion of the frame may be integrally formed in the lower portion of the table top during the molding process as part of a unit, constructed in one piece. Furthermore, a plurality of depressions can be disposed on a lower surface of the table top, and at least a large part of the plurality of depressions can be generally aligned in a first direction. Furthermore, a plurality of channels may be disposed in the receiving portion of the frame and each channel of the plurality of channels generally aligned in a second direction 10 different from the first direction. The first and second support elements can be connected to the table top.
If desired, the first direction of the plurality of depressions may be generally perpendicular to the direction of the second plurality of channels. Furthermore, at least one channel of the plurality of channels may be disposed on the receiving portion of the frame and on a portion of an edge. Furthermore, the receiving portion of the frame may have a generally U-shaped configuration with a first side, a top surface and a second side wall. The plurality of depressions can be disposed on the upper surface of the receiving portion of the frame and the plurality of channels can be disposed at least partially on the sidewall in the first sidewall and the upper surface of the receiving portion of the frame.

Each channel of the plurality of channels may be disposed at least partially on the first side wall and the upper surface of the receiving portion of the frame, or at least partially disposed on the first side wall, the upper surface and the second side wall of the receiving portion of the frame. Finally, an edge may extend below the lower surface of the table top and the edge may include a sidewall generally aligned and coplanar with a sidewall of the receiving portion of the frame. One or more of the channels of the plurality of channels may be at least partially disposed on the edge sidewall and the sidewall of the receiving portion of the frame.

The present invention is generally directed to a table. The principles of the present invention, however, are not limited to tables. It should be understood that, in light of the present disclosure, the tables disclosed herein can have a variety of shapes, sizes, configurations and arrangements. In addition, while the tables shown in the accompanying figures are illustrated as being dining tables or utility tables, it should be noted that the tables may be of other suitable types of tables, such as round tables, staff, conference, games. Furthermore, the invention disclosed herein can be successfully used in connection with other types of furniture and/or structures.
Additionally, to aid in describing preferred embodiments of tables, words such as top, bottom, front, rear, right and left may be used to describe the accompanying figures, which may be, but not necessarily, drawn to scale. It will be further appreciated that the tables can be arranged in a variety of desired positions or orientations, and used in various locations, environments and arrangements. A detailed description of the exemplary table modalities is now provided.
As shown in Figures 1 and 2, an exemplary table 10 may include a table top 12 and the table top may be constructed of molded plastic. Table top 12 may include an upper portion 14 such as an upper surface, a lower portion 16 such as a lower portion and a perimeter 18. As shown in the accompanying figures, a side wall may be disposed over the perimeter 18 of the table top 12. The upper portion 14 may be spaced apart from the lower portion 16 of the table top 20 12 by a distance, which may be a generally constant distance. The table top 12 may also include a hollow inner portion disposed between the top and bottom portions 14, 16 of the table top. In addition, the table top 12 may include an edge 20 which may extend below the lower portion 16 of the table top.
Table top 12 may further include one or more sides 22, corners 24 and ends 26. Table top 12 including top 14, bottom 16, hollow inner portion, edge 20, sides 22, corners 24 and/or ends 26 can be formed integrally as part of a unit, constructed in one piece during the molding process. If table top 12 is constructed of plastic, it can be formed into the desired shape by blow molding, injection molding, rotary molding, or other suitable processes. It will also be appreciated that table top 12 can be constructed using various materials such as wood, metal and the like.
Table 10 can also include one or more support structures 28 that can be sized and configured to support table top 12 on a surface, such as a floor or floor. The support structures 28 may include one or more legs or supports 30 and the support structures may be moved between an in-use or extended position and a storage or stowed position with respect to the portion of the table top 12. As shown in the figures attached, the support structures 28 may include a pair of legs or supports 30 and a connecting element 32 to interconnect the supports.
The table 10 may include a frame 36 that is connected to the portion of the table top 12. If desired, the support structures 28 can be connected to the frame 36. In addition, the support structures 28 can be movably connected to the frame. 36 to allow the legs 30 to move between a use or extended position and a stowed or collected position. For example, support structures 28 could include or be attached to cross members 38, 40 and legs 30 could be attached to cross members. Cross members 38, 40 can be connected to frame 36. In particular, frame 36 can include elongated elements such as side rails 42, 44 and cross members 38, 40 can be attached to side rails. It will be appreciated that the cross members 38, 40 may also be a part of the frame 36.
The support structures 28 and/or the legs 30, however, need not be connected to the cross members 38, 40 or the frame 36. Instead, the support structures 28 and/or the legs 30 can be connected to any of the suitable parts of table 10. It will also be appreciated that table 10 may include any suitable number of support structures 28 and/or legs 30 depending, for example, on the intended use of the table. It will also be appreciated that the table top 12, support structures 28 and legs 30 may have various sizes, shapes, configurations and arrangements depending on, for example, the intended use of table 10. It will further be appreciated that frame 36, side rails 42, 44 and/or cross members 38, 40 are not needed; and table 10 can have other components, features, features, features, and the like, if desired.
The table 10 may also include first and second sets of clamps 46, 48, which can be connected with the support structures 28. In particular, the set of clamps 46, 48 may be connected to the legs 30 and may be dimensioned and configured to allow the legs to move between use and storage positions. As shown in Figure 2, the clamp assembly 46, 48 may include a first portion 50A connected to the legs 30 and a second portion 50B connected to a cross member 52 and/or the table top portion 12. The first and second portions 50A, 50B can be interconnected to form the bracket assembly 46, 48.
Table 10 is preferably sized and configured to be stacked with one or more additional tables. In particular, the stacked tables 10 are preferably fitted together to reduce the height of the stacked tables, which can allow tables to be transported, stored and shipped in a smaller area. This can result in a significant cost reduction for the manufacturer because, for example, less storage space can be required and a substantial reduction in transport costs can be achieved. An exemplary embodiment of nested and stacked tables is shown in figures 13 and 14, which will be discussed in more detail below. Features, additional aspects, and exemplary embodiments of nested and stacked tables are shown in the applicant's own US Patent Application Serial Number 13/455,041 entitled TABLES WITH NESTING TABLE TOPS, filed April 24, 2012; US patent application serial number 13/455,055, entitled FRAME FOR A TABLE, filed April 24, 2012; and US patent application serial number 13/455,066, entitled TABLE, filed April 24, 2012. Each such application is incorporated herein by reference in its entirety.
The frame 36 can be sized and configured to facilitate the seating of the tables 10. For example, as shown in Figure 2, the side rails, 42, 44 of the frame 36 can be arranged along the sides 22 of the table top 12. Advantageously , the side rails 42, 44 are disposed close to the sides 22 of the table top 12, so the sides of the table top can be supported by the frame 36, which can help to create a strong and resistant table 10. In addition, side rails 42, 44 can be sized and configured to help transfer forces in the center portion of the table and away from the perimeter 18, which also helps to create a strong and strong table 10.
As shown in Figures 1 to 4, the table 10 may include a handle 54 disposed at one or both ends 26 of the table top 12. The handle 54 is preferably sized and configured to facilitate the displacement and transportation of the table 10. In addition, Handle 5 54 can help separate tables 10 in the docked configuration. The handle 54 may consist of a recess or opening in the edge 20 of the table top 12 and the handle may be integrally formed with the table top as part of a unit constructed in one piece.
Table 10 may also include openings 56 disposed in edge 20 along sides 22 of table top 12.
The openings 56 can be sized and configured to allow a portion of the frame 36, such as the outer surface 58 of the frame, to be visible or exposed along the sides 22 of the table top 12. This can allow for, for example, a The consumer will easily see the exposed surface 58 of the frame 36. Therefore, the table top 12 may include openings 56 in the sides 22 to allow a portion of the frame 36 to be exposed and open at the ends 26 to form the handles 54. Thus, the table top Table 12 may include openings on both sides 22 and ends 26 and openings 56 on sides may be much larger than handles 54 by a factor of five, ten, twenty or more.
As shown in the accompanying figures, the table top 12 can include a plurality of depressions 60. The depressions 60 can be sized, formed, configured and arranged to provide greater strength, strength and/or rigidity for the table top 12. The depressions 60 may also encompass most, substantially all, or all of the lower portion 16 of table top 12. In addition, depressions 60 may have a generally uniform shape, size, configuration, and arrangement. The dips 60 may also have an elongated shape that is axis-aligned and the dips may be aligned in a series of rows and columns that extend along the length and width of the table top 12. adjacent rows and columns can be compensated for and the distance between depressions in adjacent rows and columns can generally be the same. For example, the distance between adjacent depressions in each row or column can generally be constant or the same. The distance between adjacent rows and columns can also be generally constant or the same.
The depressions 60 can be used to create a table top 12 with generally uniform characteristics or qualities. For example, if the depressions 60 are consistently spaced, they can allow an upper surface 62 of the table top 12 to be evenly supported. Furthermore, if the depressions 60 are separated by a generally constant distance, which can be measured from a center of a depression to a center of an adjacent depression, these can create a table top 12 with more uniform characteristics or qualities. The distance between adjacent depressions 60 can be measured longitudinally, laterally or at an angle depending on, for example, the arrangement of the depressions.
The depressions 60 may also be arranged in a pattern and the depressions may generally be aligned and/or arranged at predetermined positions within the pattern. The pattern may include, for example, a number of rows 64 and/or columns 66 of depressions 60. Rows 64 may be arranged along a length of table top 12 and columns 66 may extend along a width of the table top. The depressions 60 can also be arranged in other suitable shapes and patterns and can have other shapes, sizes, configurations and arrangements, depending, for example, on the intended use of the table 10.
A plurality of depressions 60 may also be disposed near the connection of frame 36 and table top 12. These depressions 60 near frame 36 may have the same size, shape, configuration and arrangement as the depressions in the pattern. The depressions 60 near frame 36 may also have other sizes, shapes, configurations and/or arrangements, as discussed in more detail below. A plurality of depressions 60 may also be disposed between the side rails 42, 44 of the frame 36 and an upper surface 62 of the table top 12. Advantageously, the depressions 60 can help support the portion of the table top 12 disposed on the rails. sides 42, 44 of frame 36, which can help prevent the table top from bending or deforming in an undesirable way. The depressions 60 can also help prevent the portions of the table top 12 disposed on the side rails 42, 44 of the frame 36 from bending or closing if a load or force is applied to that portion of the table top.
The depressions 60 may also have different characteristics depending on, for example, a particular configuration of the depressions. For example, depressions 60 can have an elongated length and a depression can have increased strength along its length. The depression 60 can also have a non-circular configuration with the force increased in one direction compared to another direction. Advantageously, if the depressions 60 have different characteristics, then the depressions can be arranged or configured so that the structure has certain characteristics. In particular, the depressions 60 can be arranged in a pattern to maximize certain features and/or create a structure with generally uniform features. For example, the pattern may include generally evenly spaced depressions 60 that are separated by a generally constant distance and/or arranged in a patterned arrangement. A consistent arrangement of depressions 60 can help create a structure with uniform characteristics. For example, a generally constant pattern of depressions 60 can create a structure with generally uniform strength and structural integrity.
The table 10, table top 12, depressions 60 and other table components may have a variety of suitable shapes, sizes, configurations and arrangements, such as disclosed in the Applicant's own U.S. Patent No. 7,069,865, entitled HIGH-STRENGTH, LIGHTWEIGHT BLOW-MOLDED PLASTIC STRUCTURES, issued July 4, 2006, which is incorporated herein by reference in its entirety. In addition, table 10, table top 12, and depressions 60 may have other suitable features and configurations, such as disclosed in the Applicant's own provisional US patent application serial number 11/372,515 entitled HIGH-STRENGTH, LIGHTWEIGHT BLOW-MOLDED PLASTIC STRUCTURES, filed March 9, 2006, currently pending, which is incorporated by reference in its entirety.
The table top 12 may also have one or more reinforcing elements 70, which may be arranged near the ends 26 of the table top. Strengthening elements 70 may also be formed on edge 20, sides 22 and/or corners 24 of table top 12.
Advantageously, the reinforcement elements 70 can increase the strength, rigidity, structural integrity and/or impact resistance of the table top 12. Additional examples of tables, table tops, depressions and reinforcement elements (along with other features, aspects and 5 components) are disclosed in the Applicant's patents 7,111,563; 7,475,643; 7,814,844 and 8,033,228; each of these requests is incorporated herein by reference in its entirety. It will be understood that the tables disclosed in this document may have different shapes, sizes, configurations and arrangements; and can include any suitable quantity and combination of features, features and components; but none of these features, aspects or components may be needed.
Table top 12 may include reinforcing elements, such as depressions 60 and/or reinforcing elements 70, disposed at least close to the stress concentrations. For example, reinforcement elements can be positioned to help reinforce the upper surface 62 and/or a lower surface 68 of the table top 12, and minimize stress concentrations such as can occur in the connection of the frame 36 and the table top of table. In particular, the reinforcing elements can be sized and configured to increase the strength, rigidity and/or strength of the table top 12 disposed above the frame 36 to minimize the unsupported areas of the table top. In addition, the reinforcement elements can increase the strength, rigidity and/or strength of the portions of the table top 12 that extend beyond the frame 36. For example, the reinforcement elements can be sized and configured to help prevent parts from falling apart. of the table top 12 bend or twist in an undesirable way, such as the edges that are arranged on the perimeter 18 of the table top 12.
As discussed above, reinforcement elements, such as depressions 60 and/or reinforcement elements 70, can be of a certain size, shape, configuration and/or arrangement 10 to provide greater strength, rigidity and/or structural integrity. Thus, reinforcement elements can have specific sizes, shapes, configurations and arrangements depending on, for example, factors such as location, use, function and the like.
As best seen in Figure 5, the table top may include stiffening elements 72 disposed proximate a frame receiving portion 74 sized and configured to receive at least a frame portion 36. In particular, frame receiving portion 74 may be 20 sized and configured to receive the side rails 42, 44 of the frame 36. The side rail 42 may contact or abut an upper surface 76 of the receiving portion of the frame 74. The side rail 42 may also contact or abut an inner side wall 78 and on an outer side wall 80 of the frame receiving portion 74. The frame receiving portion 74 may be integrally formed with the lower surface 68 of the table top 12 as part of a unit constructed in one piece.
The reinforcement elements 72 may be sandwiched or disposed between an upper surface of the side rail 42, 44 and the upper surface 62 of the table top 12. For example, the reinforcement elements 72 may include an end disposed proximal to an upper surface of the table top. side rail 42, 44 and an opposite end, contacting the top surface 62 of the table top 12.
The reinforcement elements 72 can also be sized and configured to facilitate airflow during the molding process, which can be particularly useful if the table top is constructed of blow molded plastic, because the receiving portion of the frame 74 may extend into the lower surface 68 of the table top 12 and may be spaced at a boundary between the upper portion of the receiving portion of the frame and the upper surface of the table top 12.
As seen in Figures 5 and 7, the reinforcement elements 72 may be disposed on the upper surface 76 of the frame receiving portion 74. The reinforcement elements 72 may extend from the upper surface 76 of the frame receiving portion 74 to the upper surface. 62 of the table top 12. As shown in the accompanying figures each of the reinforcing elements 72 may be a groove or rib which is formed in the upper surface 76 of the receiving portion of the frame 74 which contacts or abuts the upper surface 62, but the elements reinforcements can also be grooves, notches, depressions or the like. The reinforcement element 72 may be entirely disposed between or confined within the inner side wall 78 and the outer side wall 80 of the frame receiving portion 74. While the reinforcement element 72 may have an elongated length as shown in the accompanying figures, reinforcement elements may also have other suitable configurations, such as round, circular, oval, oblong, and the like.
The reinforcement elements 72 can be sized, formed, configured and arranged to provide greater strength, strength and/or rigidity for the table top 12. The reinforcement elements 72 can also be used to create a table top 12 with more. uniform characteristics or qualities. Advantageously, the gussets 72 can help support the portion of the table top 12 disposed on the side rails 42, 44, which can help prevent the table top from undesirably flexing or otherwise deforming. The reinforcing elements 72 can also help prevent the portion of the table top 12 disposed on the side rails 42, 44 from bending or closing if a load or force is applied to the portion of the table top.
As best seen in Figures 5 and 7, the table top 12 may include a first group or plurality of reinforcement elements 72, which may be substantially or entirely disposed on the upper surface 76 of the receiving portion of the frame 74. The reinforcement elements 72 may have an elongated length that is disposed in a first direction, such as generally perpendicular to the length of table top 12 and located between the sides of inner and outer walls 78, 80 of the receiving portion of the frame 74. gusset 72 may have a generally constant or consistent spacing, size, shape, configuration and/or arrangement. Furthermore, the reinforcement elements 72 can be arranged along the axis and/or in a parallel configuration, and the adjacent reinforcement elements in the receiving portion of the frame 74 can be separated from each other by a generally constant distance.
Table top 12 can also include a second group or plurality of gussets 82. The second plurality of gussets 82 can be generally the same size, shape, configuration, and arrangement. The second plurality of reinforcing elements 82 may also be separated by a generally consistent distance. As shown in the accompanying figures, the first and second plurality of reinforcing elements 72, 82 may have different shapes, size configurations and/or arrangements.
For example, the reinforcing elements 72, 82 may be arranged at different angles, such as at right angles to each other, or in different directions. For example, in the present embodiment, if the first plurality of reinforcement elements 72 is generally aligned with the length of the table top 12, then the second plurality of reinforcement elements 82 may be generally aligned with the width of the table top of table. If desired, the reinforcement elements 72, 82 may alternate between a reinforcement element of the first plurality of reinforcement elements and the second plurality of reinforcement elements.
As shown in Figures 5 and 7, the reinforcing elements 72, 82 may have different configurations. For example, the reinforcing element 82 may be a rib or channel which extends the entire width of the frame receiving portion 74 and may be disposed at least partially in one or more of the side walls 78, 80 of the frame receiving portion. frame. If the frame-receiving portion 74 is aligned with the edge 20, the reinforcing member 82 may also be formed at the edge, such as on an inner sidewall 84 of the edge. Reinforcement element 82 may be disposed perpendicular to edge 20 or an edge of table top 12, such as sides 22 and reinforcement elements may be arranged in a parallel configuration. The reinforcing elements 82 can be sized and configured to prevent bending or twisting 25 of the external parts of the table top 12 that are not supported by the frame 36.
In more detail, the reinforcement element 82 may be formed in the inner side wall 78 of the frame receiving portion 74 and the reinforcement element may extend along all or only a portion of the inner side wall 5 . The reinforcement element 82 may also extend over the entire width of the upper surface 76 of the frame receiving portion 74. In addition, the reinforcement element 82 may be formed in the outer wall 80 of the frame receiving portion 74 and/or the side wall 84 of edge 10 20.
As best seen in Figure 5, the reinforcing element 82 can have different sizes and configurations. For example, some of the reinforcing elements 82 may be larger or smaller. Advantageously, because the reinforcement elements 82 can be disposed on both the frame-receiving portion 74 and the edge of 20, the reinforcement elements can help to connect the frame-receiving portion and the edge. The reinforcing elements 82 can also provide greater strength, strength and/or rigidity for these 20 portions of the table top 12. For example, the reinforcing elements 82 can increase the strength, rigidity and/or strength of the portions of the table top. 12 that extend or are disposed beyond frame 36, such as edge 20. In addition, reinforcing elements 82 may be sized and configured to prevent edge 20 from bending or deforming in an undesirable way. Therefore, in an exemplary embodiment, a first plurality of depressions or reinforcement elements 72 and a second plurality of depressions or reinforcement elements 82 may be disposed between the side rails 42, 44 and the upper portion 14 or upper surface 62 of the table top 12. As shown in figure 9, the side rails, 42, 44 may include an upper portion or surface 86 which contacts the lower surface 68 of the table top 12. In addition, the plurality of reinforcing elements 72 may be disposed between a first side 88A and a second side 88B of the upper portion or surface 86 of the side rails 42, 44.
As discussed above, depressions 60, reinforcing elements 72 and reinforcing elements 82 can provide increased strength, rigidity and/or structural integrity.
These structures can also support the portions of the table top 12, such as the portions disposed on the side rails 42, 44 of the frame and the portions that extend beyond the frame 36. Advantageously, this can allow the table top 20 12 have more uniform features.
As shown in Figures 9, 11 and 12, table top 12 may include a receiving portion 90 that is sized and configured to facilitate docking of the tables. The receiving portion 90 may be disposed at least partially on the upper portion 14 or upper surface 62 of the table top 12 and may be sized and configured to receive a coupling portion 92 of an adjacent table when the tables are arranged in a configuration. docked. The receiving portion 90 is preferably arranged over the perimeter 18 of the table top 12. In particular, the receiving portion 90 is preferably arranged over the entire perimeter 18 of the table top 12, including sides 22, corners 24 and ends 26. Desirably, the receiving portion 90 may be disposed below a plane in line with the upper surface 62 of the table top 12.
The receiving portion 90 may be integrally formed with the table top 12 as part of a unit, constructed in one piece during the molding process, if the table top is constructed of molded plastic. In more detail, the receiving portion 90 can be disposed at least close to the intersection of the top surface 62 and an outer edge of the table top 12. In addition, the receiving portion 90 can have a generally L-shaped configuration is open. on both sides, which can help facilitate the alignment and docking of the tables 10.
The coupling portion 92 may be a frame portion 36, such as a side rail portion, 42, 44, and/or a table top portion 12, such as an edge portion 20, the sides 22, the corners. 24 and/or ends 26. If desired, edge portions 20, sides 22, corners 24 and/or ends 26 disposed in receiving portion 90 may include pressing edges.
Therefore, the coupling portion 92 disposed on the receiving portion 90 may include a combination of one or more portions of the frame 36 and/or table top 12. The receiving portion 90 and the coupling portion 92 may have various shapes, sizes, configurations and arrangements, as shown in patent application serial number 13/455,041, entitled TABLES WITH NESTING TABLE TOPS, filed April 24, 2012; US patent application serial numbers 13/455,055, entitled FRAME FOR A TABLE, filed April 24, 2012; and US Provisional Patent Application Serial Number 13/455,066, entitled TABLE, filed April 24, 2012, all in the Applicant's own name. Each of these requests is incorporated herein by reference in its entirety.
As shown in the accompanying figures, the receiving portion 90 is preferably disposed on the perimeter 18 of the table top 12, including the sides 22, the corners 24 and the ends 26. Furthermore, the receiving portion 90 may be at least partially disposed on the upper surface 62 20 and at the edge of the table top 12, and the receiving portion may be disposed below in a plane generally aligned with the upper surface of the table top. The receiving portion 90 may be integrally formed with the table top 12 as part of a unit, constructed in one piece during the molding process, if the table top is constructed of molded plastic.
As shown in Figure 14, the receiving portion 90 can have a generally L-shaped configuration that is open on both sides, which can facilitate the alignment and coupling of the tables 10. The receiving portion 90 can be a rib. or channel with a height and width. For example, a side wall 106 of the receiving portion 90 may have a height between 0.25 inches (0.63 cm) and about 0.3 inches (0.762 cm) or 0.4 inches (1.016 cm) and a lower surface 106 of the receiving portion 90 may have a width that is greater than the height by a factor such as two, three or more. For example, the width can be approximately twice the height such that, in the exemplary embodiment, if the height is about 0.25 inches (0.63 cm), then the width can be about 0.5 inches. .27 cm). The height and width can also be approximately the same. For example, if the height is about 0.5 inches (1.27 cm), then the width can also be about 0.5 inches (1.27 cm). It will be appreciated that the width can also be less than the height. So, for example, if the height is about 0.4 inches (1.0 cm), then the width might be about 0.3 inches (0.76 cm) or less. It should be understood that the height and/or width of the receiving portion 90 may vary depending on, for example, the intended use of the table 10.
The receiving portion 90 may be supported by reinforcement elements and/or depressions 94 disposed in the lower portion 16 of the table top 12. For example, as shown in Figure 11, the reinforcement elements 94 may include an inner portion 96 (such as an inner or upper surface) that contacts, abuts or engages an inner portion 598 (such as an inner surface) of the receiving portion 90.
In more detail, the reinforcement elements 94 may extend internally or horizontally with respect to the lower portion 16 of the table 12. For example, the reinforcement elements 94 may be disposed along the sides 22 or ends 26 of the table top. 12. In particular, the reinforcing elements 94 may be disposed on the inner sidewall 84 of the edge 20 and have a generally curved or arc-shaped configuration. An inner surface of the reinforcement element 94 may be spaced beyond an outer wall of the edge 20 and the inner portion 96 of the reinforcement elements may contact the inner portion 98 of the receiving portion 90. For a table 10 having about six feet ( 1.8 meters) long and thirty-two reinforcement elements 94 may be disposed along each side 22 of the table top 10. It will be appreciated that more or less reinforcement elements 94 may be disposed along the sides 22 and/ or ends 26 of table top 12 depending, for example, on the length or intended use of table 10.
As shown in Figures 4 to 7 and 10 to 11, for example, reinforcement elements 94 may be disposed on the side wall 84 of edge 20. Reinforcement elements 94 may also be disposed at corners 24 as shown in Figures 2 and 12. Advantageously, the reinforcing elements 94 may also be constituted of and/or be referred to as 5 depressions. In addition, as discussed below, one or more depressions may be used to connect the receiving portion 90 and the reinforcement elements 94. It will be understood in light of the present disclosure that the reinforcement elements 94 may have different shapes, sizes, configurations. and arrangements depending, for example, on the intended use of table 10.
Strengthening elements 94 may also be arranged at other angles and/or connected to the inner portion 98 of the receiving portion 90 in different configurations and arrangements.
For example, as shown in Figure 12, the reinforcing elements 94 may be disposed at the corners 24 of the table top 12. The reinforcing elements 94 at the corners 24 may extend upwards from the lower surface 68 of the table top 12. In greater detail, the inner portion 96 of the reinforcement element 94 at the corner 24 may contact, abut or engage with the inner portion 98 of the receiving portion 90. In particular, the inner portion 96 of the reinforcement elements 94 may contact the inner portion 98 of the receiving portion 90, such as the inner surface of a lower portion 100 and/or an inner surface of the sidewall 102. Each corner 24 of the table top 12 may include eight connections between the reinforcing elements 94 and the receiving portion 90. It is understood that the table 10 may have any number of suitable connections between the reinforcement elements 94 and the receiving portion 90, the reinforcement elements may be disposed in any suitable parts of the table top 12 and the support elements. reinforcement can have other sizes, shapes, configurations and arrangements depending, for example, on the intended use of the table 10.
Advantageously, the reinforcing elements 94 can provide greater strength, support, rigidity and structural integrity to the receiving portion 90. The reinforcing elements 94 can also allow the receiving portion 90 to sustain a considerable amount of weight or force. Significantly, this can allow a number of tables 10 to be arranged in a nested configuration, because, for example, tables arranged at the bottom of the stack do not get damaged by the weight of the tables. For example, when the tables 10 are fitted together as shown in Figures 13 and 14, the coupling portion 92 may contact or abut the lower surface 104 and/or the side wall 106 of the receiving portion 90 and these may become the surfaces of load-bearing. Because the reinforcing elements 94 can increase the strength, rigidity and/or structural integrity of the receiving portion 90, this can allow a considerable number of tables 10 to be stacked and fitted together without causing damage to the receiving portion.
One or more depressions may also support the receiving portion 90. For example, one or more depressions may connect to the reinforcement element 94 and the receiving portion 90.
In addition, one or more depressions may be formed in edge 20 and/or lower portion 14 of table top 12 and the depressions may contact, mate with or abut inner portion 98 of receiving portion 90.
The table 10 can also include other structures that can increase the strength, rigidity and/or structural integrity of the table top 12. For example, the lower surface 68 of the table top 12 can include one or more recesses 110, which are dimensioned and configured to receive a structural support element, such as a portion of the support structure 28, the frame 36, the cross member 38, the cross member 40 and/or the cross member 52.
For example, as shown in Figure 16, a first cross-member recess 112 can be sized and configured to receive a cross-member portion 38 and a second cross-member recess 114 can be sized and configured to receive a cross-member portion. 40. The third recess of the cross member 116 may be dimensioned and configured to receive the cross member 52 disposed near the center of the table top 12. The lower surface 68 of the table top 12 may also include a first recess of the support structure. 118 and a second support frame recess 120 which are dimensioned and configured to receive the support frames 28 in the stowed or closed position. The recesses 112, 114, 5 116, 118 and 120 can facilitate the engagement of the tables 10 by allowing an upper portion of an adjacent stacked table to be disposed on a lower portion of the table. Recesses 112, 114, 116, 118 and 120 can also help to position the various components in the desired position.
The lower surface 68 of table top 12 may also include one or more grooves 122, which may be aligned in a parallel configuration. The channels 122 may have a width generally equal to the width of the depressions 60 in the lower surface 68 and the channels are preferably aligned with the depressions.
Advantageously, because the channels 122 can be aligned and generally have the same width as the depressions 60, the channels may not interrupt or interfere with the generally uniform pattern or arrangement of the 20 disposed depressions. The channels 122, however, can have a width that is greater or less than the width of the depressions 60, if desired.
As shown in Figures 15 to 19, a plurality of depressions 124 may be disposed in a lower portion 126 of channel 122 and the depressions may contact, abut, or engage with the upper surface 62 of the table top 12.
The depressions 124 may be generally of the same pattern, spacing, size, shape, configuration and arrangement. In addition, the depressions 124 in the lower portion 126 of the trough 122 may be generally arranged in the same pattern as the depressions 60 in the lower surface 68. Significantly, if the depressions 60, 124 are arranged in the general pattern, this can create a table top 12 with generally uniform characteristics such as strength, rigidity and structural 10 integrity.
Channels 122 can have a variety of different lengths. For example, some of the channels 122 may have a length that allows only a limited number of depressions 124, such as three, to be disposed in the lower portion 126. Other channels 122 may have a longer length that allows a greater number of depressions 124 is disposed in the lower portion 126, such as ten or twelve. In addition, other channels 122 may extend from one end to the other end of table top 12. It will be appreciated that channels 122 may be of any suitable length.
Channels 122 can be sized, formed, configured, or arranged to increase the strength, rigidity, structural integrity and/or torsional strength of table top 12. For example, channels 122 can have opposing walls 128, 130 and walls opposites can increase the strength, rigidity, structural integrity and/or torsional strength of the table top 12. The lower portion 126 of the grooves can also be spaced close to the upper surface 62 and can increase the rigidity, strength, structural integrity and/ or torsional strength of the table top 10.
Channels 122 preferably are disposed on both sides of a structural support element, such as transverse elements 38, 40. In particular, channels 122 preferably extend through a recess of the transverse element, such as the first and second cross member recesses 112, 114 and pass through both sides of the cross member recess. Furthermore, a depression may be disposed at an intersection of one or more of the channels 122 and the recess of the transverse member. In addition, the ends of the channels 122 are preferably disposed close to a portion of the table top 12 that is not directly supported by the frame 36. For example, the ends of the channels 122 may be disposed near the ends 26 of the table top 12, which can extend beyond the ends of the side rails 42, 44 and the cross members, 38, 40. In particular, a first end of each channel 122 of the plurality of 25 channels may be disposed close to a first end of the top of The table and the ends of the channels may generally be spaced a distance equal to the first end of the table top. Channels 122 can also be of different lengths. Advantageously, channels 122 and depressions 124 can increase the strength, strength, rigidity and/or structural integrity near the structural support elements and accompanying recesses and the ends 26 of the table top 12. Significantly, this can prevent the ends 26 of table top 12 rotate or move downwardly relative to cross member 38, 40 and/or ends of frame 36, which can increase the torsional strength of table top 12.
As seen in Figures 18 and 19, the bottom surface 68 can be spaced a generally constant distance from the top surface 62 so that the table top 12 has a generally constant height or thickness. The various structures arranged on the lower surface 68 of the table top 12 can be of different heights. For example, the cross member recesses 112, 114, 116 may have a height that is slightly less than the thickness of the table top 12. The frame receiving portion 74 may have a height that is less than the thickness of the table top 12 and the height of the cross member recess 112. The lower portion 126 of the channels 122 may also have a height that is less than the thickness of the table top 12 and the height of the cross member recess 112 As shown in the accompanying figures, the height of the receiving portion of the frame 74 and the channel 122 can be approximately the same. Thus, the height of the recess of the cross member 112, 114, 116 may be between the height of the frame receiving portion 74 and the channel 122. Because the height of the frame receiving portion 74 and the channel 122 may be the same, and because of this. while the frame's receiving portion may include reinforcement elements 72, 82 and the channel may include depressions 124, the upper surface 62 of the table top 12 may generally have similar characteristics, such as strength, rigidity and structural integrity.
In this exemplary configuration, the upper surface 62 of the table top 12 can be generally uniformly supported, which can allow the table top to have generally consistent characteristics and qualities, such as strength, rigidity, structural integrity and smoothness. from the top surface. It will be appreciated that table 10 and table top 12 may also have 20 other suitable features, appearances, configurations, and the like, as disclosed in US patent application serial number 13/455,076, entitled TABLE WITH MOLDED PLASTIC TABLE TOP, filed at April 24, 2012; and U.S. Patent Application Serial Number 25 13/455,081, entitled TABLE TOP, filed April 24, 2012. Each such patent application is incorporated by reference in its entirety.
A person versed in the art, after reviewing this disclosure, will notice that the tables revealed here can have different aspects, characteristics and configurations. Furthermore, a table can have any suitable number of aspects, features, properties and configurations depending, for example, on the use of the table.
While this invention has been described in terms of certain preferred embodiments, other embodiments will become apparent to those skilled in the art and will also be within the scope of this invention. Therefore, the scope of the invention is intended to be defined by the claims which follow.
