    [0001] [0001] The present invention relates to hanging objects that can be loosened and adjustable on surfaces such as walls, and with hanging systems that can be loosened. BACKGROUND
    [0002] [0002] There are several ways to hang things on the walls. Some people drill permanent holes in the wall, such as nails and tacks. Other people have adhesive, but some stickers used to hang things damage the wall when removed. More recently, adhesive bonding systems have been introduced, which can be removed without damaging most wall surfaces, by progressively stretching the adhesive in a shear mode to separate a hook suspension device, for example, from the Wall.
    [0003] [0003] Some things hanging on the walls are flexible, such as posters and papers. Others, such as images with frames and frames, are rigid and have greater difficulty in removal if connected with adhesive close to the walls, because they cannot be flexed to separate them from the wall.
    [0004] [0004] When using some hanging techniques, care must be taken to properly align and place the hanging components, so that the objects being hung are level and at the desired height, for example.
    [0005] [0005] Other systems for hanging things in a way that can be loosened, particularly rigid things, on surfaces such as walls, are sought. SUMMARY
    [0006] [0006] In general, several innovative aspects of the subject described in this specification present a hangable system that can be loosened including a strap fastener component and a hook fastener component in combination with one or more of the innovative aspects described below.
    [0007] [0007] In a first aspect, hanging an object with a releasable hang system includes selecting a desired orientation of the object with respect to a vertical surface having a first area of touch fasteners and holding a second area of fastener elements touch next to the back side of the object. One of the first and second areas of touch fastener elements includes an arrangement of male touch fastener elements, each extending from a common base. The other of the first and second areas of touch fastener elements includes several fibers distributed over an area and which can be engaged by the touch fastener male elements. The object is hung on the vertical surface with the fibers engaged so that they can be released by the male touch fastener elements.
    [0008] [0008] In a second aspect, hanging an object with a hangable hang system includes selecting a desired orientation of the object with respect to the vertical surface and attaching a second area of touch fastener elements to a back side of the object . A first area of touch fastener elements is engaged so that it can be released with the second area of touch fastener elements. One of the first and second areas of touch fastener elements includes an arrangement of male touch fastener elements, each extending from a common base. The other one between the first and the second area of touch fastener elements includes several fibers distributed over an area and can be engaged by the male touch fastener elements. The object is hung on the vertical surface by holding the first area of touch fastener elements close to the vertical surface.
    [0009] [0009] In the first and second aspects, a significant majority of male touch-fastener elements are oriented to be attached to the base in a single common direction, each male touch-fastener element of the significant majority extending from the base to one distal tip. As used in this document, "a significant majority" can range, for example, from at least 75 percent of the male touch fastener elements to essentially all male touch fastener elements. In some instances, at least 90 percent or at least 95 percent of the male touch fastener elements are oriented to go over the base in a single common direction. The orientation of the significant majority of the male touch fastener elements is such that, with the object hanging from the vertical surface, the fastening elements of the significant majority support the weight of the object in a downward direction and so that the significant majority of the male fastener elements touch are oriented so as not to inhibit the lifting of the object in an upward direction.
    [0010] [00010] In some implementations, the second area of touch fastener elements includes the scratch of male touch fastener elements. The back side of the object can be flat in an area where the second area of touch fastener elements is secure. The vertical surface on which the object is hung, a region on the back side of the object where the second area of touch fastener elements is secure, or both, can be rigid. Holding the second area of touch fastener elements close to the back side of the object may include attaching multiple separate plates close to the back side of the object, each plate carrying a portion of the second area of touch fastener elements. In some cases, the plates are separated horizontally on the back side of the object in the selected orientation with respect to the vertical surface. After hanging the object on the vertical surface, an angular orientation of the object on the vertical surface can be changed by sliding a face one side of the object upward along the vertical surface, with respect to an opposite side face of the object.
    [0011] [00011] In various aspects, a hanger system that can be loosened includes a handle fastener and a hook fastener. The loop fastener component includes a flexible plate supporting an area of fibers that can be engaged exposed on one front side of the plate an adhesive on one side of the plate. The hook fastener component includes a resin base supporting an arrangement of male touch fastener elements, each of the significant majority of male touch fastener elements extending from the base to a distal post, to project over the base on a single common direction.
    [0012] [00012] In one of several aspects, the hook fastener component includes a visible indication, different from the orientation of the male touch fastener elements themselves, of the common direction in which the significant majority of the male fastener elements project on the base or a direction opposite to the common direction in which the significant majority of the male touch fastener elements project over the base.
    [0013] [00013] In another of the various aspects, the hook and loop fastening components are configured to engage with each other to form a looseable fixture having an overall engaged thickness of less than around 0.5 millimeters, and an engaged shear gap of less than 10 per cent of the total engaged thickness.
    [0014] [00014] In another among the various aspects, the hook and loop fastener components are configured to engage with each other to form a release that can be released having an initial shear resistance, loaded in opposition to the common direction of the significant majority of male touch fastener elements, which is more than 10 times an initial shear resistance of the fixture that can be loosely loaded in the common direction of the significant majority of the male touch fastener elements.
    [0015] [00015] In yet another of several aspects, the hook and loop fastener components are configured to provide a peel force of at least 2.00 kg / m (0.1 pounds per inch) of closing width when taken off in as opposed to the common direction of the significant majority of male touch fastener elements.
    [0016] [00016] In some implementations of the aspects of the subject, the significant majority of male touch fastener elements comprise at least 75 percent of the male touch fastener elements. In some implementations, the significant majority of the male touch fastener elements comprise essentially all the male touch fastener elements. The male touch fastener elements have rods extending contiguously from the resin base, so that together they form a contiguous resin mass. The male touch fastener elements can be arranged in rows and columns, each row and column comprising multiple male touch fastener elements. The density of the male touch fastener elements is preferably at least 350 male touch fastener elements per square inch of the resin base. For various applications, some or most of the male catch elements of the significant majority have non-recessed tips, meaning that the tips do not extend back to the base. Instead, the tips are substantially parallel, or are directly away from an upper surface of the base from which the male touch fastener elements extend.
    [0017] [00017] In some implementations, the visible indication of the single common direction in which the significant majority of the male fastener elements project over the base (or a direction opposite to the common direction in which the significant majority of the male fastener elements touch). project on the base) is a general shape of the hook fastener component. Alternatively, or in addition, the visible indication includes a graphic element printed on the hook fastener component. In some cases, the hook fastener component includes an adhesive on the back side of the hook fastener component, a release liner covering the adhesive, and a visible indication provided (e.g., printed) on the release liner. The adhesive on the back side of the strap fastener component, the back side of the hook fastener component, or both, can be a pressure sensitive adhesive.
    [0018] [00018] The various aspects of the invention described above can be combined for particular advantage in different embodiments. In addition, the embodiments can be provided with other aspects. In one example, a hangable system that can be released may include instructions for attaching a first of the fastener components to the object, adhering a second of the fastener components to a surface from which to hang the object, engaging the loop fastener component and the hook fastener component, and adjusting an orientation of the object with respect to the surface. In another example, a release system that can be loosened includes instructions for removing the first of the clamping components from the object, for removing the second of the clamping components from the surface, or for a combination thereof.
    [0019] [00019] Advantages of some combinations of embodiments described in this document include the ability to adjust the orientation of an object with respect to a vertical surface without repositioning the fastener attached to the wall and without repositioning the fastener attached to the object. Other advantages of some combinations of embodiments described in this document include the ability to release the vertical surface and object fastening components without damaging the vertical surface or object finish.
    [0020] [00020] Details of one or more embodiments of the invention are set out in the accompanying drawings and in the description below. Other aspects, objectives and advantages of the invention will be apparent from the description and the drawings, and from the claims. DESCRIPTION OF THE DRAWINGS

    [0042] [00042] Hanging an object so that it can be dropped onto a vertical surface may include selecting a vertical surface having a first area of touch fastening elements, selecting a desired orientation of an object with respect to the vertical surface, attaching a second area of touch touch fastener elements next to a back side of the object, and hang the object on the vertical surface by engaging it so that the first and second touch fastener elements area can be released. In some implementations, hanging an object so that it can be dropped onto a vertical surface includes selecting a vertical surface, selecting a desired orientation of an object with respect to the vertical surface, attaching a first area of touch fastener elements to the vertical surface, attach a second area of touch fastener elements to a rear side of the object, and hang the object on the vertical surface by engaging the first and second area of touch fastener elements. In other implementations, hanging an object so that it can be dropped onto a vertical surface includes selecting a vertical surface, selecting a desired orientation of an object with respect to the vertical surface, attaching a second area of touch fastener elements to one side of behind the object, engage so that a first area of touch fastener elements can be released with the second area of touch fastener elements, and hang the object on the vertical surface by attaching the first area of touch fastener elements to the vertical surface .
    [0043] [00043] One or both of the vertical surface on which the object is hung and a region on the back side of the object where the second area of touch fastener elements is attached can be rigid. In some cases, the vertical surface is a wall. The object to be hung on the vertical surface can be, for example, a picture, a decorative tile, or another rigid object. The back side of the object can be flat in an area where the second area of touch fastener elements is attached.
    [0044] [00044] One of the first and second areas of the touch fastener element includes a hook fastener component, with an arrangement of male touch fastener elements, each being extending from a common base. A significant majority of the male touch fastener elements are oriented to project over the base in a single common direction. Each significant touch male catch element extends from the base to a distal tip. Some or all of the distal tips may be non-reentrant tips. The orientation of the significant majority of male touch fastener elements is such that, with the object hanging on the vertical surface, the fastening elements of the significant majority support the weight of the object in a downward direction and so that the significant majority of the male fastener elements touch is oriented so as not to inhibit the lifting of the object in an upward direction. The other one between the first and second area of touch fastener elements includes a loop fastener component, with several fibers or loop fastener elements distributed across an area and can be engaged with the male touch fastener elements.
    [0045] [00045] In some cases, the first area of touch fastener elements includes male touch fastener elements and the second area of touch fastener elements includes handle fastener elements. The first area of touch fastener elements is attached to the vertical surface so that a significant majority of the male touch fastener elements are oriented to project onto the base in an upward direction with respect to the vertical surface. In other cases, the first area of touch fastener elements includes handle fastener elements, and the second area of touch fastener elements includes male touch fastener elements. The second area of touch fastener elements is attached to a rear side of the object so that a significant majority of the male touch fastener elements are oriented to overlap the base in a downward direction with respect to the vertical surface. In one example, the first area of touch fastener elements is a handle fastener surface, with an area of handle material that exceeds the dimensions of the back side of the object. For example, the vertical surface can be a video card, a wall panel, a billboard, or a room dividing wall with a surface including a handle material so that it can be loosened and can be engaged by a first area of male touch-fastener elements attached to the back side of an object.
    [0046] [00046] In one implementation, FIG. 1 represents components of the hangable system that can be released 100 configured to hang an object so that it can be released from a vertical surface. The releasable hang system 100 includes a first area of touch fasteners 102 and a second area of touch fasteners 104. The first area of touch fasteners 102 includes one or more handle fasteners 106. The loop fastener components 106 include an exposed area of attachable fibers or loop fastener elements 108 supported on a front side of a flexible plate 10, with an adhesive on the back side of the plate to attach the loop fastener component together to a vertical surface 112. Several handle fasteners 106 can be separated (e.g., horizontally and vertically) on the vertical surface 112 to form the first area of touch fasteners 102.
    [0047] [00047] The second area of touch fastener elements 104 includes one or more hook fastener components 114. Hook fastener components 114 include an arrangement of male touch fastener elements 116 and an adhesive on a back side of the touch fastener component. hook to secure the hook fastener component to an object 118 to be hung from the vertical surface 112. Several hook fastener components 114 can be separated (e.g., horizontally and / or vertically) on the back side of the object 118. In one example, several hook fastener components 114 are separated horizontally on the back side of object 118 in a selected orientation with respect to the vertical surface 112. To hang object 118 so that it can be released from the vertical surface 112, elements touch fastener males 116 in the hook fastener components 114 are engaged so that they can be released with the handle fastener elements 108 in the c loop holder components 106. With the object 118 hanging from the vertical surface 112, as shown in FIG. 3, the male touch fastener elements 116 of the significant majority projecting over the base in a single common direction (i.e., downwards with respect to the vertical surface 112) support the weight of the object 18 in a downward direction.
    [0048] [00048] In another implementation, FIG. 2 represents hook fastener components 114 attached to the object 118 and so that they can be loosely engaged with the loop fastener components 106. To hang the object 118 so that it can be released from the vertical surface 112, a location and orientation desired objects with respect to the vertical surface are selected. The handle clip components 106 are attached to the vertical surface 112 with an adhesive on the back side of the handle clip components by pressing object 118 against the vertical surface. Attaching the handle clip components 106 to the vertical surface 12 hangs the object 118 so that it can be released from the vertical surface.
    [0049] [00049] With the object 118 hanging so that it can be released from the vertical surface 12, a significant majority of the male touch fastener elements are oriented so as not to inhibit the lifting of the object in an upward direction. As indicated by the arrows in FIG. 3, an orientation of object 118 can be adjusted with respect to the vertical surface 112. Adjusting an orientation of object 118 with respect to the vertical surface 112 can include sliding a side face 300 of the object upward along the vertical surface with respect to a face opposite side 302 of the object to change an angular orientation of the object on the vertical surface.
    [0050] [00050] Referring to FIG. 4A, an upper part of a hook fastener component 114 of a releasable hanger system 100 includes an arrangement 400 of male touch fastener elements 116 arranged in rows 402 and columns 404 extending outwardly from a sheet-shaped base 406, and together form a contiguous resin mass with the base. The male touch fastener elements 116 are arranged with a density of at least 350 male touch fastener elements per square inch of the resin base. A significant majority of the male touch fasteners 116 are oriented to project over the base 406 in a single common direction, each male touch fastener extending from the base to a distal tip 408. Some or all of the tips 408 they are non-reentrant tips. FIG. 4A presents an arrangement of male touch fastener elements 116 with essentially all male touch fastener elements oriented to project over the base 406 in a single common direction. FIG. 4B presents an arrangement of male touch-fastener elements 116 with some of the male touch-fastener elements 116 oriented to project over the base 406 in a direction opposite to that of the significant majority of the male touch-fastener elements.
    [0051] [00051] US Patent Application No. 61 / 328,257 filed on April 27, 2010 and called "Male Touch Fastener Element", which is incorporated herein in its entirety by reference, describes male touch fastener elements suitable for use in hanging systems that can be released. As shown in FIG. 5A, the male touch fastener 116 includes a head 500 having a tip 408 and extending from a rod 502. The tip 408 is a non-recessed tip. The male touch fastener elements 116 can be engaged in two directions along a plane (i.e., an engagement plane) parallel to the leaf-shaped base 406 in the direction of the columns 404 (FIG. 4A).
    [0052] [00052] Now, referring to FIGS. 5A, 5B and 5C, the male touch fastener 116 has a substantially constant thickness from the base to the tip, and includes a rod 502 rising from a base 406, and a head 500 projecting over the base a from a front side 506 of the stem 502 to a distal edge at the tip 408. A boundary surface of generally curved retention space 508 is formed, in lateral profile, by the front side 506 of the stem 502, by a underside 510 of the head 500, and an upper surface 504 of the base 406. The boundary surface 508 forms, in its innermost extension 512, a retaining cavity 514 defined between the curvature discontinuities 516, 518 spaced from both the base 406 and the distal tip 408.
    [0053] [00053] In the various implementations, curvature discontinuities 516, 518 are of a single type. For example, FIG. 6 illustrates an alternative implementation of a male touch fastener element 600 in which the curvature discontinuities include inflection points 602, 604 in which the boundary surface 508 changes from being concave upwards (i.e. positive curvature) to concave downwards ( that is, negative curvature), and vice versa. In contrast, FIG. 7 illustrates an implementation of a fastener element 700 in which the curvature discontinuities are different and include an angled corner 702 and a rounded corner 704. As illustrated in FIGS. 6 and 7, some implementations include a deeper and / or lower retention cavity 514. These and other features vary between implementations to achieve varying degrees of performance with respect to resistance to detachment and / or to slow the handle break.
    [0054] [00054] Again referring to FIG. 5B, the retaining cavity 514 is bounded by a concave wall of cavity 520. The concave wall of cavity 520 defines a constant radius of curvature 522. In particular, some examples include a constant radius of curvature 522 of less than 30 percent of a total height 524 of the male touch fastener 116 above the top surface 504 of the base 406. In other examples, the radius of curvature 522 varies (ie the distance as measured in the side profile from the innermost extension 512 of the bordering surface 508 to the concave wall of cavity 522). For example, as illustrated in FIG. 7, a variable radius of curvature 522, as measured in the side profile, increases from corner 704 to corner 702. In each example, the radius of curvature is preferably between about 0.003 mm to 0.08 mm (0.001 to 0.003 inches).
    [0055] [00055] The height, depth and size of the holding cavity 514 and the general dimensions of the male touch fastener 116 are shaped to achieve a desired peel thickness, stem thickness and / or to achieve a desired proportion of these parameters for the general dimensions of the male touch fastener. Further details of this fastener design can be found in US Patent Application No. 61 / 328,257.
    [0056] [00056] By "peeling thickness" is meant the thickness of the male touch fastener 116 as measured on the side profile along a 45 degree line with the upper surface of the base and extending from the front side of the stem to the back side of the head, so that the line is normal to the front side of the stem at an intersection point. For example, in FIG. 5A, line 526 forms a 45 degree angle 528 with the top surface 504 of base 406 and extends from the front side 506 of the rod 502 to the back side of the head 500 so that the line 526 is normal to the side of the stem 502 at an intersection point 530. The intersection point in FIG. 5A is inside the retaining cavity 514. In some implementations without a retaining cavity, the point of intersection occurs at a point along the boundary surface 508.
    [0057] [00057] Each male touch fastener 116 has a peel thickness ratio for an elevation 530 of the intersection point 532 (measured from the top surface 504 of the base 406) which is greater than 0.75, and preferably , greater than 0.85. Additionally, in some examples, the innermost extension 512 of the boundary surface 508 is arranged at an elevation 530 above the upper surface of the base 406 so that the elevation 534 is less than half the overall height 524 of the fastener 116 above the upper surface 504 of base 406. In addition, in some embodiments, the head 500 is shaped so that the innermost extension 512 of the boundary surface 508 and a part further in front of the distal tip 408 form a line 536 extending at an angle 538 having a value between about 20 and 40 degrees to base 406, and preferably, 30 degrees.
    [0058] [00058] The male touch fastener 116 includes a stem thickness 540, measured parallel to the base 406 in a region of the innermost extension 542 in a vertical plane 544 crossing the boundary surface 508, which is at least twice an elevation 534 from the region of the innermost extension above the upper surface 505 of the base 406. When the distal tip 408 is directed along the row 404 of the male touch fastener 116, the stem 502 has a thickness 540 that is at least 1.7 times an elevation 534 of the region of the innermost extension 542 above the upper surface 504 of the base 406.
    [0059] [00059] For some applications, the aspects described in this document are combined with male touch fastener elements of different shapes, such as Omo J hooks and palm trees. FIGS. 8A and 8B illustrate a J 800 hook fastener including a tapered recessed tip 408, a holding cavity 514, and the generally curved sides 802, 804.
    [0060] [00060] FIG. 9 illustrates a palm-type clamping element 900 extending from base 406. Several individual raised parts 902 ascend from base 406. In this embodiment, each individual raised part 902, in its upper central region, supports a male clamping element of individual touch 904. The upper surface of the base 406 is located at a distance A below the top of the male fastener elements 804, defining the space of the handle S in which the handles can reside. The male touch-fastener element 904 includes the stem 906 and the head 908. The raised part 902 includes the elements 910, 912 that extend, respectively, in the opposite lateral directions beyond the stem 902. The head 908 includes two head parts 914 , 916 projecting laterally in opposite directions, projecting over opposite sides 918 and 920 of the stem 906 and defining loop regions 922 and 924 above the upper surfaces 926 and 928 of the base parts 910 and 912. Each region of handle 922, 924 thus has a substantially high lower limit which improves the likelihood that the handles entering over the hovering head parts will be engaged by the tips 930 and 932 of the head. In addition, the relative smallness of the stem 906 compared to the head elevation A 908 (or elevation B of the head tips 930, 932) allows the fastening elements to have desirable resistance to lateral curvature both in the plane on which the tips are located and in the orthogonal plane. Additional details with respect to the palm-type male touch fastener 900 are found in US Patent 7,516,524 to Provost and others, which is incorporated herein by reference.
    [0061] [00061] FIG. 10 is an SEM image of an arrangement of male touch fastener elements including a significant majority of non-reentrant male touch fastener elements 1000 and palm touch type male elements 1002. As seen in FIG. 10, each palm-type male touch-holding element 1002 has two recessed tips 1004, with one end projecting over the base in the same direction as the direction of the non-re-entering points of the male touch-holding elements 1000 and one end protruding over the base in the opposite direction as the non-reentrant tapping male elements.
    [0062] [00062] A percentage of male touch fastener elements that project over the base in a single common direction can be calculated as follows. In one example, a statistically representative part of an arrangement of male touch-fastener elements similar to that shown in Fig. 10 has 10 non-reentrant male touch-fastener elements and 10 palm-type male touch-fastener elements. As shown in FIG. 10, essentially all male non-reentrant touch fasteners project onto the base in a single common direction. The palm-type tapping elements overlap the base in two directions: the direction of the significant majority (that is, the direction of the non-reentrant tapping elements 1000) and the direction opposite to the significant majority. The percentage of tips of the male touch fastener projecting over the base in the direction of the significant majority is (100 + 10) / (100 + 20) or around 92 per cent. In another example, an arrangement of male touch fastener elements includes 88.8 percent of unidirectional male touch fastener elements with non-reentrant tips with a density of 1713 elements per square inch, and 11.2 percent of male fastener elements. palm touch with a density of 216 male touch-fastener elements per square inch, for a total of 1929 male touch-fastener elements per square inch. The total number of tips per square inch is 1713 + 2 (216) = 2145, with 89.9 percent of the tips facing in one direction and 10.1 percent of the tips facing in the opposite direction.
    [0063] [00063] The male touch fastener elements of FIGS. 4A to 10 can be molded into the presented formats using one or more techniques. For example, in a molding technique, a thermoplastic resin is extruded as a molten sheet from the extruder and inserted into a jaw formed between a pressure roller and a counter-rotating defining shaped cavities of the fastener element on its surface. The pressure on the jaw causes the thermoplastic resin to enter forming cavities with a blunt end to form the fastening elements, while the excess resin remains around the periphery of the mold roll and is molded between the rollers to form the shaped base. sheet. The thermoplastic resin is cooled as it continues along the periphery of the mold roll, solidifying the fastening elements, until it is cut by a separating roll. The molded clamping elements expand during demoulding, but tend to substantially cover their shape as molded. Additional details with respect to processing are described in US Patent 4,775,310 to Fisher and US Patent 6,802,260 to Clune and others, the disclosures of which are incorporated herein in their entirety by reference.
    [0064] [00064] In some embodiments, the mold roll includes a face-to-face assembly of thin circular rings or plates that are, for example, around 0.0762 mm to 6.35 mm (0.003 inches to around 0.250 inches) thick, some having cuts on their periphery defining mold cavities and others having solid circumferences, serving to close the open sides of the mold cavities and serve as spacers, defining the spacing between adjacent rows of fastener element. A fully "constructed" mold roll can have a width, for example, of around 1.91 cm to 15.24 cm (0.75 inches to around 6 inches) or more and can contain, for example, from around 50 to 1000 or more individual rings. Additional details with respect to mold tooling are described in US Patent 4,775,310 to Fischer.
    [0065] [00065] The cavities that constitute the male touch fastener elements shown in FIGS. 5A through 7 have angled edges and straight side walls (for example, see side walls 546, 548 shown in FIG. 5C) and create fastening elements with substantially similar cross sections through the thickness of the fastening element. Tooling with side walls and straight edges can be manufactured, for example, by laser cutting, EDM wire or electroforming. Additional details with respect to the laser cut mold and EDM wire tooling are described in US Patent 4,775,310 to Fischer. The electroforming process is described in US Patent 7,052,638 to Clarner and others, the disclosure of which is incorporated herein in its entirety by reference.
    [0066] [00066] In contrast, the male touch fastener elements formed in the cavities that have been, for example, photochemically treated may have rounded surfaces in some or all regions, from the base to the tip, just like the fasteners illustrated in FIGS . 8A and 8B. For example, surfaces on top of the heads can be manufactured to taper to a point to provide a wedge effect. A wedge shape can, for example, assist in the entry of the hook into the face of an associated loop fastener component. Additional details with respect to photochemical treatment are described in US Patent 6,163939 to Lacey et al., The entire disclosure of which is incorporated by reference in this document.
    [0067] [00067] An alternative technique for molding fastener elements is similar to the one described above, except only that a mold roll is used, that is, no pressure roll is needed. Here, the extruder is shaped to conform to the periphery of the mold roll and the extruded resin is introduced under pressure directly into a space formed between the mold roll and the extruder. The molded fastener component is separated from the mold cavities by a separator roller as described above. Additional details with respect to this process are described by US Patents 5,781,969 and 5,913,482 to Akeno, the disclosures of which are incorporated herein in their entirety by reference.
    [0068] [00068] In some cases, the male touch fastener elements are not molded into their final shape. In any of the methods disclosed above, for example, the hook fastener component can be directed through a subsequent processing station to finalize the shape of the male touch fastener elements. Such subsequent processing may include "flat topping" projecting over preforms of male touch-holding element, as described by US Patent 5,953,797 to Provost and US Patent 5,781,969 to Akeno, the disclosures of which are incorporated by reference in its entirety in this document. In some cases, even straight shaped rods can subsequently be processed to result in fastening elements having the properties disclosed in this document. Fastening elements with flat sides with the profiles shown in FIG. 5C can also be formed by a die-cut method, such as the method disclosed in US Patent 4,895,569 to Nestegard, for example, which is incorporated herein in its entirety by reference. In such processes, moldable renin is extruded through a die with openings shaped in the desired profile of the hook, then the extruded rails are cut across the extrusion direction, and the base stretched in the extrusion direction to separate the rails into rows of fastening elements distinct. This procedure results in fastening elements with wide sides that are cut instead of molded, as in the processes described above, and with profile edges formed by sliding resin through a formatted matrix instead of a filling cavity.
    [0069] [00069] FIG. 11 shows a side view of part of a hook fastener component 114 with male touch fasteners 116 on a common base 406. As shown in FIG. 11, the hook fastener component 114 is a laminate including a laminating adhesive 1100, a poly (ethylene terephthalate) film 1102, a pressure sensitive silicone adhesive 1104, and an optional release liner 1106 such as, for example , a protective fluoropolymer coating. In some implementations, a thickness of the laminating adhesive ranges from 0.05 to 0.01 mm (0.002 to 0.004 inches), a PET film thickness ranges from 0.025 to 0.05 mm (0.001 to 0.002 inches), a thickness of pressure sensitive silicone adhesive ranges from 0.012 to 0.025 mm (0.0005 to 0.001 inches), and a thickness of the Vaira release liner from 0.025 to 0.05 mm (0.001 to 0.002 inches). One or more additional intermediate layers may be present between the base 406 and the pressure sensitive silicone adhesive 1104 or the base and the release coating 1106. The release coating 106 is removed from the pressure sensitive silicone adhesive 1104 before the component hook fastener 114 if attached to an object 118 with the pressure sensitive adhesive.
    [0070] [00070] As described with respect to FIG. 1, the hook fastener component 114 is configured to be attached to the object 118 with a significant majority of the male touch fastener elements 116 projecting over the base in a downward direction relative to the vertical surface 112, so that the elements tapping males of the significant majority protruding over the base in a single common direction support the weight of the object in a downward direction. In some implementations, the hook fastening components include a visible indication, different from the orientation of the male touch fastening elements themselves, from the orientation in which the hook fastening component is to be attached to the object so that the significant majority of the hook ends. male touch fastening elements protrude over the base in a downward direction with respect to the vertical surface. Examples of such visible indications are shown in FIGS. 12A to 12C.
    [0071] [00071] For example, FIG. 12A illustrates a hook fastener component 114 with a general shape indicative of the orientation in which the hook fastener component is to be attached to the object so that the male touch fastener elements 116 of the significant majority projecting over the base 406 in one single common direction support the weight of a hanging object so that it can be released from a vertical surface in a downward direction. FIG. 12B shows a hook fastener component 114 with a graphic indication 1200 of the desired orientation of the hook fastener component with respect to the vertical surface 112. The graphic indication 1200 is visible on the hook side of the hook fastener component 114 and indicates a desired orientation of the hook fastener component with respect to the vertical surface 112. In some implementations, the graphic indication 1200 is printed on the hook side of the hook fastener component 114 with an inkjet process using wax-based ink. Printers suitable for applying a wax-based ink to the hook surface of a hook fastener component are available, for example, from Markem Corporation (Keene, NH). FIG. 12C shows a perspective view of a hook fastener component 114 with a graphic indication of the desired orientation of the hook fastener component in relation to the vertical surface 112 printed on the adhesive side of the hook fastener component (for example, on the adhesive side of the base 406, pressure sensitive silicone adhesive layer 1104, or release liner 1106).
    [0072] [00072] The hook fastener component 114 is designed to engage tightly with a low-hemp loop fastener component, particularly a loop component with handles formed of knitted or non-woven materials. Non-woven materials are described in US Patent 6,329,016 to Shepard, which is fully incorporated herein by reference. Non-woven loop materials are constructed, for example, from a layer of fibers or filaments that have relatively high or high loop regions between regions attached by adhesives or self-adhesive bonds. Handle 3905, from Velcro USA, Inc., is an example of a suitable mesh handle material.
    [0073] [00073] FIG. 13 shows a side view of a part of a loop fastener component 106 of a hangable system 100. Loop fastener component 106 is a flexible plate supporting an area of fibers that can be engaged 108 exposed in one layer base 1300. As shown in FIG. 13, handle clip 106 is a laminate with a laminating adhesive 1100, a poly (ethylene terephthalate) film 1102, a pressure sensitive silicone adhesive 1104, and an optional release liner 1106 such as, for example , a protective fluoropolymer coating. The thicknesses of these layers are similar to the thicknesses described for the layers of the hook fastener components. In some implementations, one or more additional intermediate layers may be present between the base 1300 and the pressure sensitive silicone adhesive 1104 or between the base and the release coating 1106. The release coating 1106 is removed from the silicone sensitive adhesive pressure 1104 before the handle clip 106 is attached to a vertical surface 112 with the pressure sensitive adhesive.
    [0074] [00074] The pressure sensitive silicone adhesive layer 1104, combined with the flexibility of the separate fastener components, together allows the hook fastener component 114 and the handle fastener component 106 to be removed without damaging the surfaces they are attached to. adhered to. For example, the handle clip 106 can be moved from a painted wall or with wallpaper without damaging the finish on the wall by vigorously peeling the handle clip back from a corner to create a curve the component at the point of detachment. Similarly, the hook fastener component 114 can be removed from the back of a decorative wall tile or other object without damaging the object. As seen in FIG. 14, the flexible grip member 106 may be detached from the surface 112 by pulling one end of the handle member at an obtuse angle θ with respect to the surface. When detached at an angle θ of 170 degrees, for example, the handle gripping components form an angular corner at the point of detachment, with an effective radius of curvature of less than around 0.64 mm (0.025 inches). In some hanging systems that can be loosened, the radius of curvature of the hook fastener component exceeds the radius of curvature of the loop fastener component. In one example, a radius of curvature for a hook fastener component is around 1 mm (0.04 inches).
    [0075] [00075] FIG. 15 illustrates a side view of a part of a hanger system that can be released 100 with the handle clip 106 engaged with the hook clip 114. "Engaged thickness" "t" is a measurement of the total thickness of the engaged closure , prepared according to paragraphs 6.1 to 8.23 of ASTM D5170-98, and then engaged in accordance with paragraph 8.24 of ASTM D5170-98, except that the roller is pushed through the lock only in one direction, for one pass, constituting half a cycle. The engaged thickness is then measured with the closure in an unloaded state, such as by optical measurement observing the closure from its longest edge. Thus, thickness measurement is performed following the initial engagement under static load of 0.23 kg (half a pound) per square inch for two seconds and a rolling load of 4.99 kg (11 pounds) per inch of the closure width .
    [0076] [00076] For some applications, the hanging system that can be advantageously loosened is configured to have a total engaged thickness between around 0.3 mm and 0.7 mm. In one example, a total latched thickness for a hanging system that can be released = e 0.46 mm (without release linings). This particularly small coupled thickness prevents large spaces of poor appearance between an object and the surface to which it is attached, and also reduces the tension forces on the hook - loop coupling caused by the projection over the object 's weight. Instead, the vast majority of the weight of relatively flat objects, such as pictures, with centers of gravity close to the wall, is exerted as a shear force on the fixation system, rather than a tension force or a force of detachment.
    [0077] [00077] FIG. 16A represents an object 118 secured so that it can be released close to a vertical surface 12 with a hangable system that can be released 100. FIGS. 16B and 16C show enlarged views of a part of the engaged loop fastener component 106 and of the hook fastener component 114 of the hangable system 100. As shown in FIG. 16B, when the hook fastener component 114 initially comes into contact with the loop fastener component 106, male touch fastener elements 116 of the hook fastener component come in contact with the fibers 108 of the loop fastener component, with a significant majority of male touch fastener elements oriented to project on the base of the hook fastener component in a downward direction relative to the vertical surface 12. The orientation of the significant majority of the male touch fastener elements 114 is such that, with the object 118 hanging on the vertical surface 112, the male touch fastening elements 114 of the significant majority support the weight of the object in a downward direction. The fiber engagement 108 of the loop fastener component 106 by the male touch fastener elements 116 of the hook fastener components 114 can be seen in FIG. 16C, for example, by the extension of the fibers 108 around the non-recessed distal tip 408 of the male touch fastener elements.
    [0078] [00078] The significant majority of the male touch fastener elements 116 are oriented so as not to inhibit the lifting of the object 118 in an upward direction. This orientation of the significant majority of the male touch fastener elements 116 (or spikes 408) allows a side face 300 of the object 118 to slide upwards along the vertical surface 112, with respect to an opposite side face 302 of the object (represented in FIG. 3) to change the angular orientation of the object on the vertical surface.
    [0079] [00079] Due to the directional nature of the hook fastener arrangement, the hook and loop fastening components will tend to be able to be separated by a much smaller peel force when peeled off in a direction opposite to the direction in which the weight of the hanging object is applied. when closing, than when detached in one direction corresponding to the application of the weight. In one example, the clamping system was separable by a Peel Force of only 2.00 kg / m (0.112 pounds per linear inch) of clamping width when properly engaged and removed in a peel-off mode by pulling on the clamping component. handle in a direction opposite to the hook members, but when detached in the opposite direction (that is, in the direction in which most hook ends extend), the detachment force required for separation was around 4.77 kg / m (0.267 pounds per linear inch). The resistance to detachment, or the amount of detachment force required for separation, from the engaged closure, is determined according to ASTM D170-98, using the option of integrating average for calculation. This standard measure is understood to be generally related to the ability of the engaged fixture to resist the detachment loads that are initially applied to an edge of the closure, and propagate through the closure as the two fastening components are separated by the detachment.
    [0080] [00080] For various applications, the hook and loop fastening components are preferably configured to engage with each other to form a release that can be loosened providing an initial shear resistance, as loaded in the common direction of most significant male elements. touch fasteners ("forward shear"), which is more than 10 times an initial shear resistance of the fastening that can be loaded in opposition to the common direction of the significant majority of the male touch fastener elements ("reverse shear") . "Initial shear strength" of the engaged lock is determined according to ASTM D169-98. This standard measure is understood as being generally related to the ability of the engaged fastener to resist the loads applied within the fastener plane. This significant difference between the forward and reverse shear characteristics of the fastening is directly related to the ease of adjustment by sliding the object fixed upwards along the vertical surface on which it hangs, for example.
    [0081] [00081] With reference to FIG. 17, to determine the shear clearance, as this phrase is used in this document, the material of the hook 1700 is laminated to a rigid substrate, such as, for example, an aluminum panel 1702 and is engaged with the handle material 1704 laminated to a second rigid substrate 1706. Fixture sample sections are prepared with 6.45 square centimeters (one inch by one inch) overlap. Substrate 1702 is then loaded in the direction shown by the arrows in Fig. 17, so that the hook elements engage with the handle elements, at a pull rate of around 6.6 mm (0.25 inches) per minute using a programmable MTS tester until a 1 gram (0.025 pound) F shear load is achieved. Once the target shear load has been reached in this direction, the shear clearance is recorded as the displacement (or movement in the plane) Δ of substrate 1702 relative to substrate 1706 in the target load, as shown in FIG. 18.
    [0082] [00082] As shown in FIG. 19, for fasteners with a significant majority of the male touch fastener elements oriented to project over the base in a single common direction, the Δ shear clearance is generally equal to the movement range in the direction in which the touch fastener male elements are embedded. on the handle elements. The position of the handle 1704 shows the extension of the handle in relation to the male touch fastener 1700. Thus, for such hanging systems that can be released, the shear clearance is understood to be the movement from the initial engagement to the limit route in a particular direction. Measuring the path limit of substrates 1702 and 1706 in the direction indicated in FIG. 17 (i.e., so that the male touch gripping elements engage with the handles as shown in FIG. 16C) at the predetermined load provides a measurement of the shear clearance Δ. This shear gap measurement is related to the degree of "loss of firmness" that a user would perceive on a hanging object as it is initially released.
    [0083] [00083] Preferably, the shear clearance is approximately 0.025 mm (0.001 inches) to 0.13 mm (0.05 inches). It is also preferable that the engaged shear clearance of the fixture is less than 10 percent (more preferably, less than 8 percent, and in some applications, less than 4 percent) of the total engaged thickness. In one example, with the hook elements engaging with the handle elements at a pull rate of around 6.3 mm (0.25 inches) per minute using a programmable MTS tester, an average shear extension or clearance of 0.075 mm (0.003 inches) was measured at the point where the extension force was 11 grams (0.025 pounds strength).
    [0084] [00084] The shear clearance can be adjusted by varying the characteristics of the hook and / or the handle. For example, the handle material having two or more handle sizes will tend to provide a lower shear clearance than a material with the largest single handle length, and longer handles generally provide more shear clearance than shorter handles. . The shear clearance can also be varied by varying the thickness of the hook head or the width or shape of the head or rod. The distribution of the male touch fastener elements in a hook fastener component can be selected to achieve a desired shear clearance. For example, a checkerboard pattern of male touch fastener elements on a hook fastener component may have less shear clearance than aligned rows of similar touch fastener elements on a hook fastener component. In addition, a higher density of male touch fastener elements generally results in less shear clearance than a lower density of similar male touch fastener elements. Thus, a smaller ratio of shear clearance to the engaged thickness can be achieved by using an appropriate combination of design aspects.
    [0085] [00085] Referring to FIG. 20, a hangable system that can be released 100 for hanging an object so that it can be released against a vertical surface includes a handle clip 106, a hook clip 114, and instructions for use 2000. The instructions can include, for example, textual or representative instructions for attaching a first of the clamping components to an object, attaching a second of the clamping components to a surface from which to hang the object, engaging the strap clamping component and the clamping component hook, and adjust an object's orientation with respect to the surface. The instructions can also describe how to remove the first of the object's fastening components and the second of the surface's fastening components.
    [0086] [00086] Although a number of examples have been described for purposes of illustration, the foregoing description is not intended to limit the scope of the invention, which is defined by the scope of the appended claims. There are and will be other examples and modifications within the scope of the following claims. For example, although the description is directed to a hangable system that can be loosened in which the handle fastener component is held close to the vertical surface and the hook fastener component is adhered to the object so that a significant majority of the male elements touch fasteners protrude over the base in a downward direction with respect to the vertical surface, in other examples, the handle fastener component is held close to the object and the hook fastener component is adhered close to the vertical surface so that a majority significant amount of the male touch fastener elements protrude above the base in an upward direction with respect to the vertical surface.
