    GLASS-CERAMIC ARTICLE
    The present invention relates to an article formed of a plate (in) vitroceramic, this plate being in particular intended to serve as a worktop or surface (including horizontal) of furniture, this plate being in particular of large dimensions (the article being for example the furniture thus formed), the article also comprising elements useful for its operation or the operation of the plate, for example heating elements, electronic components, etc.
    Vitroceramic has been used for several years to form vitroceramic hobs, which are very popular with housewives, appliance manufacturers and users by their attractiveness and ease of cleaning.
    Worktops are generally made of other materials, such as wood, quartz, Corian®, etc., however the use of ceramic hobs to achieve these work plans, although inducing problems specific to this material, is particularly interesting.
    A glass-ceramic is originally a glass, said precursor glass (or mother glass or green-glass), whose specific chemical composition can cause by suitable heat treatments, called ceramization, a controlled crystallization. This specific partly crystallized structure gives the glass ceramic unique properties.
    Each glass-ceramic product is the result of specific studies and numerous tests, since it is very difficult to make modifications on glass-ceramics and / or on their method of obtaining without risking an adverse effect on the desired properties: for example, in its usual use as a hotplate, a glass-ceramic plate must generally have a transmission in the visible range both low enough to mask the heating elements underlying the rest and high enough for the user to visually detect said elements in working order for safety purposes and / or read any displays. The vitroceramic plates must also have sufficient mechanical strength as required for their use, in particular, and even more so when they are of large size, in particular, in the field of household appliances, they must have a good resistance (defined, for example according to standard EN 60335-2-6 in their usual use as hotplates) to pressure, shock (support and falling of utensils, etc.), etc.
    In order to fulfill the function or functions assigned to it, the glass-ceramic plate is generally provided with additional accessories or elements (decorative or functional) required for its final use (for example heating elements or a control panel for the baking plates), in particular electronic components, said elements or accessories being generally fixed to the plate permanently, by embedding in a housing of the plate provided for this purpose, and / or possible bonding in a separate zone of that of the possible heating zones. The position and the choice of the accessories are thus fixed in advance, and once the plate and its accessories mounted, if an element is defective, the disassembly of the whole with the aid of specific tools must be operated, even repair involves changing the entire plate or assembly. The disassembly operation is rendered all the more complicated by the fact that the glass-ceramic plates are heavy, in particular the large plates, and are generally fixed to their support, by inserting a gasket, if necessary, for safety and security reasons. seal. Consequently, the use of the glass-ceramic combined with electronic components for making worktops or interactive and / or multipurpose furniture surfaces poses problems in terms of assembly or disassembly of the components, especially when is to realize modular installations, any intervention being particularly complex and may cause a change of the assembly in case of defective element.
    The present invention has therefore sought to develop an article, such as a worktop or a piece of furniture, formed of at least one glass-ceramic plate and elements necessary for its operation (in particular of electronic equipment), in particular hidden by said plate within said article during its operation, this article allowing easier maintenance of those of its constituents necessary for its operation which are normally hidden by said plate in operation, without resorting to specific tools and without having to change the plate.
    This object has been achieved by the article according to the invention, this article being in particular a worktop or piece of furniture, or another appliance particularly for domestic use and / or furniture, this article being formed of at least one glass-ceramic plate and elements for its operation (the plate being for example intended to be equipped with electronic components for different uses, and in particular able to cover or receive heating elements), at least one of said elements being positioned on a two- or three-dimensional support (such as a tray or a box) movable coupled to a safety device (or protection), such as a circuit breaker or a switch or a switch, so that in a first position of the support (operating position of the element or elements), said element (positioned on the support) is opposite a face of the plate (in particular its lower face) at a distance (perpendicularly nt to said face and between said face and the end closest to the element) of at most 10 cm from the plate and can be activated, and in a second position of the support, obtained by movement thereof, wherein at least one of the ends (or one of the edges) of the support is moved a distance (or at a distance) of at least 2 mm from the plate perpendicular to that (in particular vertically), and is displaced by a distance (or is at a distance) of at least 5 cm (perpendicularly or otherwise from the plate) relative to its first position (or position that it occupies in the first position of the support), said element is deactivated (advantageously by the action of the safety device).
    Preferably, several elements (or at least part of the set of elements) useful for the operation of the plate or the article, or all the elements allowing the operation of the plate or the article, are positioned (or placed on the movable support so that, in a first position (first and second designating relative positions, not necessarily in this order, other intermediate or additional positions may also possibly be provided) of the support (operating position of the elements and / or the plate), said elements are opposite a face of the plate (in particular its lower face) at a distance (perpendicular to said face and between said face and the nearest end of each said elements) at most 10 cm from the plate and can be activated, and in a second position of the support, obtained by movement thereof, wherein at least one of the ends (or one of the edges) of the support is moved by, or is at a distance of at least 2 mm from the plate perpendicular thereto, and is moved from, or distance of at least 5 cm from its first position, at least a part (or all) of said elements are deactivated (advantageously by the action of the safety device), certain elements presenting little danger (for example a tablet or a light source whose voltage required for operation is less than 12V AC or 30V DC), and connected to electrical circuits independent of those concerned by the safety device, which may, if necessary, remain active.
    The movable support may be in particular in the form of a tray, or a box or housing (particularly open), for example in a material such as aluminum, stainless steel glass, laminate, etc. , this support preferably being situated under the plate and being able to occupy a surface corresponding to all or part of that of the face of the plate opposite which it is in the first position of the support, the support being generally arranged parallel or approximately parallel to said face of the plate in said first position. The support may be movable in translation and / or rotation, horizontally and / or vertically, so as to move it at least partly away from the plate in the second position mentioned according to the invention, the support being further coupled to a device safety device, this device being in particular a circuit breaker or formed of at least one circuit breaker, manual or automatic, triggered in particular by the movement of the plate and which can be, or be activated, at various points in the course of the plateau, according to the device used and the degree of security sought, to allow easy and secure access to the elements, allowing the operation of the plate or the article, positioned on the support. The safety device may also be, for example formed of a contactor defusing when moving the support thus preventing the normal use of the electrical system.
    The support is preferably mobile in rotation and / or in at least two directions, for example vertically and horizontally, in order to move both the elements vertically off the plate and to offset them (or offset) horizontally relative to their first position. , in particular by allowing them, if necessary, to leave the space delimited by the plate and under which they are in their operating position (first position of the support), these elements being in particular always hidden by the plate in their position. of operation and can thus be extracted from the enclosure of the article (in particular, where appropriate, the enclosure of the closed cabinet or in a compact position) and become visible and accessible when an intervention or a replacement must be performed on at least one of them.
    The movement of the support can be done for example along an axis of rotation (for example located along an edge opposite to that intended to be removed from the plate and by which is provided the access of an operator to the elements located on the support, as subsequently illustrated, or locally around a suitable axis, such as for example a hatch under the plate, etc.) or along (guide) rails or slides, where appropriate of shape ( s) allowing vertical and horizontal movement, for example approximately S-shaped rails, as subsequently illustrated, or following one or more racks, etc. The support may for example in the latter case be in the form of a drawer or be part of a drawer or be in a drawer, this support sliding along slides and can be extracted in whole or in part furniture or article in which it is found, for example by pulling handles on the outer wall of the drawer, as shown later.
    In the first position of the support, the elements situated on the support are opposite the underside of the plate at a distance of at most 10 cm, and preferably at most 4 cm, from the plate (measured perpendicularly at said face and between said face and the end nearest to each element), and particularly preferably at a distance of less than 1 cm, advantageously less than 5 mm, the elements that may be in contact with the plate ( for example, inductors) or at a short distance, for example at least 1 mm or a few millimeters, from the latter, depending on the elements considered, this first position notably allowing these elements to perform their functions; in the second position of the support, at least one of its ends, or even the entire support, is displaced from, or is at a distance of at least 2 mm, and preferably from minus 1 cm, with respect to the plate perpendicularly to this one (in particular that the movement of the support does not damage, in particular does not scratch, the plate), and is moved from (in the same movement as that to exclude the support of the plate or in a second movement, simultaneous or consecutive), or is at a distance of at least 5 cm, in particular at least 10 cm, particularly preferably at least 15 cm, at least 50 cm from its first position (this distance being measured between the two positions), this distance also preferably corresponding to at least 30% or even at least 100% of the length or depth of the plate, so that the elements are well clear of the plate and acc. essibles. In particular, in the second position, at least one of the ends of the support, or even the entire support, is displaced from or at a distance of at least 10 cm from its first position vertically, for example by rotating or lowering the support, and / or is displaced from, or is at a distance of at least 2 mm from the plate vertically and at least 5 cm, in particular at least 10 cm, particularly preferred at least 15 cm, in particular at least 50 cm, horizontally with respect to its first position, for example by lowering and then translating the support, the displacement being made in particular by translation or by rotation, with in particular in this last case an angle of at least 2.5 °, in particular at least 10 °, or at least 20 °, or even at least 30 °, in particular at least 45 °, or at least 60 ° °, compared to the first position.
    The safety device (or protection) is preferably formed of at least one component or device for cutting electricity supplying at least a portion of the elements on the support (such as, where appropriate, the heating elements to avoid all burns) when the support passes from the first to the second position and / or in case of an electrical short circuit, and is for example in the form of a device (circuit breaker, contactor, switch, etc.), with mechanical or electrical action, integrated, at least for a part of said apparatus or device, with the electrical system (s) to be cut (the other or another part, in particular possibly located on the support) and triggered for example by the movement of the support.
    If necessary the article may also comprise (or the plate may also be coupled to) a safety device (independent or not of the aforementioned safety device) to prevent the operator from pinching or too abrupt movement of the support during its actuation, such as a brake or damper, or the article may comprise or the plate being coupled to (an integral safety device) one or more stops or one or more latches or one or more devices or locking systems or locking when the support is in (at least) one of its use positions (in particular its first and / or second position) in order to ensure, if necessary, sufficient stability of the support in this position or in each position.
    The support (or article according to the invention) can also provide other components, such as one or handles to handle it, the article can also be provided with various elements (positioned on the support or not) as detailed later. If necessary, the support can also be in several parts, each operable independently or not. The article of the invention allows easier maintenance of those of its constituents necessary for its operation which are hidden by the glass-ceramic plate forming one of its surfaces, this maintenance can be done safely, without requiring tedious disassembly and without involve the replacement of external elements such as the plate, and thus saving time, while avoiding excessive costs in case of malfunction of the elements. In addition, the proposed solution avoids having to manipulate and move the glass-ceramic plate which is particularly heavy, especially when it is large, and avoids any damage to said plate or elements necessary for its operation, while allowing said elements of perform their function in operating position in combination with the plate (such as heating, lighting of heating zones or display of data by said elements).
    The vitroceramic plate advantageously occupies the essential (more than 50% of the surface of the face where it is located, preferably more than 80%, in particular more than 90%) or the entire surface of a face, in particular the upper face of the article according to the invention, providing a continuous surface that can serve as a support for different articles according to the intended use of said plate or said article. If necessary, it rests, generally on its periphery, on at least one box or one or support feet, without it being necessary if necessary to insert a seal (or without intermediate seal) between these parts (contrary to devices in which the glass-ceramic plate occupies only part of this surface in which it is embedded). The vitroceramic plate is also advantageously monolithic (or monobloc or in one piece), and essentially flat (with the exception of possible localized deformations operated on the substrate for aesthetic and / or functional purposes). The plate thus offers a predominantly continuous / uniform / seamless surface, aesthetic and easy maintenance. The plate may, if necessary, be provided with decorative or functional coatings of small thickness (in particular of the order of a few tens of nanometers to a few hundred microns or more), for example in enamel, paint, thin layers, etc. as specified later, or may be decorated by sanding or engraving, etc.
    When the article is a piece of furniture or worktop, the glass-ceramic plate may in particular have a surface (length by width of its face of greater dimensions) greater than or equal to 0.7 m2, preferably greater than 0.9 m2, in particular greater than 1 m2, or even greater than 2 m2 Preferably in this case it also has one and / or the other of the following characteristics (the given limits being included): Young's modulus between 80 and 100 GPa (measured according to the ASTM C 1259), bending strength between 110 and 220 MPa (measured by ring test on a tripod, on a plate 70 mm X 70 mm X 4 mm, the sample resting on 3 balls of 9.5 mm diameter positioned at the top of an equilateral triangle inscribed in a circle 40 mm in diameter, a force being applied to the center of the sample by a ring 10 mm in diameter with an advance of 5 mm / min, the results being interpreted with the mod Weibull, described in: "A Statistical Distribution of Strength of Materials", Royal Swedish Institute for Engineering Research, W. Weibull, Stockholm 1939, 1-45, obtained data, also called "scale factor", revealing the mean breaking stress resulting from the Weibull method analysis of flexural modulus of rupture (MOR) measurements, expressed in MPa), thermal conductivity less than 2 W / mK (measured according to DIN 51936), impact resistance 250 to 700 ° C, density between 2.3 and 2.7, acid resistance of between 0 and 2 mg / cm 2 (measured according to DIN12116), and base resistance of between 0 and 1 mg / cm 2 (measured according to ISO 695).
    The glass-ceramic plate according to the invention is advantageously flat (or predominantly or almost flat), and in particular has a flatness (height between the highest point and the lowest point of the substrate relative to the mean plane of the substrate, at least 1 mm). except for possible voluntary deformations made on the substrate for aesthetic or functional purposes) less than 0.1% of the diagonal of the substrate, and preferably less than 3 mm, especially less than 2 mm, in particular less than 1 mm, or even of the order of zero, depending on the size / surface / diagonal of the substrate, the flatness being measured with a reference ondulometer SurFlat marketed by Visuol. The plate is generally of geometric shape, in particular rectangular, even square, or even circular or oval, etc., and generally has an "upper" face (visible face) in the use position, another "lower" face (generally hidden , in the frame or cabinet of the furniture incorporating said plate) in the position of use, and a wafer (or edge or thickness). The upper face is generally flat and smooth but may also have at least one raised zone and / or at least one hollow zone and / or at least one opening and / or beveled edges, etc., these shape variations advantageously constituting variations. Continuous plate (without changing materials or fittings). The lower face may be particularly smooth or provided with pins increasing its mechanical strength and obtained for example by rolling. The thickness of the glass-ceramic plate is generally at least 2 mm, in particular at least 2.5 mm, and is generally less than 30 mm, in particular less than 15 mm, in particular of the order of 3 to 15 mm.
    The glass-ceramic has a coefficient of expansion that is zero or almost zero, in particular less than 30 × 10 -7 K -1, between 20 and 400 ° C., and preferably less than 13 × 10 -7 K -1, between 20 and 400 ° C., and in particular a lithium aluminosilicate glass ceramic. It can be particularly dark (black, dark brown) or light (white, cream), and can be translucent or opaque or transparent depending on the desired use and aesthetics. It can be refined with arsenic (that is to say (parent glass of) composition comprising from about 0.5% to 1.5% by weight of arsenic oxide (expressed as As 2 O 3), or can not refined with arsenic (in particular having an arsenic oxides content of less than 0.2%, in particular less than 0.1%, or even zero) or refined with tin or refined with the sulphide (s) and can be obtained by rolling or floating.
    In most cases and preferably according to the invention, the plate used to form the article according to the invention is monolithic and has both a thickness of less than 15 mm, a coefficient of expansion of less than 30 × 10 -7 K 1 between 20 and 400 ° C, and a surface greater than or equal to 0.7 m2 The article according to the invention is also formed of elements necessary for its operation, more particularly necessary for the operation of the aforementioned vitroceramic plate. These elements may be, for example, one or more heating elements (for example induction coils), one or more display systems, one or more electronic boards, one or more light sources, one or more control boxes or interfaces, one or more sensors, one or more chargers (for example telephone, induction coil, etc.), in particular without wires, one or more cables, one or more sound or vibrating components (for example signaling the approach of a pan-like object), etc.
    For example, the plate may be equipped with one or more light sources, in particular formed by light-emitting diodes, and intended, for example, to materialize (make visible) one or more zones or one or more elements or displays of the plate, in particular by means of light transmission through the plate. These sources can in particular allow the display of commands (in the form of keys, logos or even keyboards, etc.), which can be activated for example by contact on the surface of the plate (using, for example, sensors located under the surface and can also be reported via the connectors) or remotely (in particular by wireless communication), or even by simple movement of the hand (by sensors located where appropriate outside and recording the movement, for example by triangulation, to convert it, notably by means of a suitable algorithm and interface, by activating a function, for example), or if necessary by placing a specific object at a specific location in the plate. The light source (s) may also allow the display of sets, or various data (eg display of computer pages, recipes, etc.) downloaded for example by wireless communication using an appropriate interface and projected or transmitted from the light sources on the surface of the plate.
    The plate may also be equipped with one or more heating elements, such as induction coils, radiant elements, which can also be activated in different ways as described for the light sources, and may also be equipped with interface (s). communication with at least one adjacent element (for example light sources or heating elements), and / or where appropriate with at least one external element, for example with an external module for wireless communication, the one or more interfaces being for example a control box, a tablet or a touch screen, a system like Bluetooth, WLAN, wifi, RFID chip, Lifi, etc.

    The plate may also comprise various functional and / or decorative coatings, in particular those generally used with glass-ceramics, for example based on enamel, paint, thin layer (s) (for example metal (s), dielectric (s), etc.), etc. For example, one of the faces may comprise one or more layers or one or more enamel patterns, for decorative purposes and / or for signaling one or more elements (displays, etc.), and / or masking (for avoid for example the direct vision of light sources), and / or for other functions (as light extractor or to homogenize lighting, etc.). The plate may also be provided with one or functional layers giving it one or more additional properties such as anti-scratches, mechanical reinforcement, anti-traces, anti-overflow, etc. the coating or coatings that can be found in particular on the apparent face or on the opposite face, depending on the type of coating and the desired function.
    The present invention relates in particular as an article, a table or a worktop or a cabinet comprising a surface or plate, in particular of large dimensions, formed by the glass-ceramic plate and adapted to allow simultaneously or successively different activities and / or object support. This piece of furniture can be for example a central room of room, such as a kitchen island, or any plan or work table for different uses, for example a lab bench, a table or a coffee table, or a piece of furniture. console type, credenza, storage unit, counter, etc. The article according to the invention is manufactured in particular from the glass ceramic plate, in particular of large dimensions, obtained by ceramization, by setting it and fixing it, for example by gluing (double-sided, silicone, magnetic tape, etc.). , where appropriate on a box or support legs and associating with it, beforehand or during its assembly, the mobile support and the elements necessary for its operation, positioned (at least partly), on the mobile support .
    As a reminder, the manufacture of the glass-ceramic plates generally takes place as follows: in a melting furnace, the glass of the chosen composition is melted to form the glass-ceramic, and then the molten glass is rolled into a standard ribbon or sheet by passing the glass melted between rolling rolls and cut the glass ribbon to the desired dimensions. The plates, already cut or not, are then ceramized in a manner known per se, the ceramization of baking the plates according to the thermal profile chosen to transform the glass into the polycrystalline material called "glass-ceramic" whose expansion coefficient is zero or almost -nul and which withstands a thermal shock up to 700 ° C. The ceramization generally comprises a stage of gradual raising of the temperature to the nucleation range, generally located in the vicinity of the glass transformation domain, a step of crossing in several minutes of the nucleation interval, a new progressive elevation of the temperature up to the temperature of the ceramic bearing, the maintenance of the temperature of the ceramic bearing for several minutes and a rapid cooling to room temperature.
    In order to obtain plates of large dimensions according to the invention, in particular plates with a surface area greater than 0.7 m 2, during the ceramization cycle, the passage rate of at least 25%, preferably of at least 25%, is preferably reduced. at least 50%, or the length of the ceramic arch or the residence time in said arch is increased by at least 25%, preferably by at least 50%, with respect to speed, length or the optimum or usual residence time to obtain a glass-ceramic substrate having a surface area of less than 0.4 m2.
    If necessary, the method also comprises a cutting operation (generally before ceramization), for example by water jet, mechanical tracing with the wheel, etc. followed by a shaping operation (grinding, beveling, ...). The method may also include a rolling or collapsing step to form particular reliefs. Other details and advantageous features will emerge below from the description of non-limiting embodiments of the invention with reference to the accompanying drawings in which: - Figure 1 shows a schematic perspective view of an article according to a first embodiment of the invention in a first position where the elements allowing its operation are hidden and can be activated; - Figure 2 shows a schematic partial side view (the side panel of the furniture and that of the drawer being removed from this side) of the article of Figure 1 in the first position of the support carrying the elements; - Figure 3 shows a schematic partial side view similar to that of Figure 2, with the difference that the support is this time in its second position where the elements are accessible and disabled. FIG. 4 represents a schematic perspective view of an article according to a second embodiment of the invention in a position of the support where the elements allowing the operation of the article are accessible and (at least for a part of the invention) of them) disabled.
    The same references are used throughout the figures to designate the same types of elements, all the elements not being represented on the same scale for a better understanding of the figures.
    In Figures 1 to 3, the article according to the invention is a piece of furniture (1), for example a kitchen island, intended for different uses (successive or simultaneous), including the preparation and consumption of dishes, the support of objects, cooking food, etc., this piece of furniture being formed of a box (2) of 240 cm (length) X 120 cm (depth) X 95 cm (height, base (2 ') of the box included) topped a worktop (3) entirely (that is to say on its entire surface) formed of a monolithic substrate (4) glass ceramic of 2.88 m2 surface. This substrate is for example a plate of the type marketed under the reference KeraBlack + by the company Eurokera, this plate having a smooth upper face and a lower face provided with pins, and a thickness of 6 mm. This substrate is for example obtained by proceeding as in the patent application WO2012156444 but reducing the rate of passage in the ceramization arch of 50%, the glass ceramic substrate obtained has a flatness of less than 2 mm. The article also includes a drawer (5), 238 cm (length) X 100 cm (depth) X 5 cm (height), provided with handles (6), and doors (7), also provided with handles (6). '), as well as elements (8) for the operation, if any, of the plate, these elements being in the present case in particular heating elements for cooking food, for example inductors, arranged under the plate . The location of the heating elements may, where appropriate, be indicated by decorations (9), for example enamel, on the surface of the plate, delimiting as necessary the heating zones (in Figure 1, four heating zones are thus shown).
    The heating elements are positioned on a support (10) in the form of a plate mounted, for example by means of a rolling system and / or carriage and / or rollers and / or pads (11), on a S-shaped guide rail (12) placed inside the drawer (in particular on each of the opposite lateral walls), the drawer being itself mounted on one or more rails (13), for example of the telescopic type. and located along each of the side edges of the drawer.
    Upon actuation of the drawer, the support, on which the heating elements and if necessary other elements for the operation of the plate or the article are, moves along the rail (12) and passes through a first position (Figure 2) where the elements are opposite the bottom face of the plate and, for at least some of them (for example the heating elements) against said plate / at a zero distance from said plate, or if necessary for others (for example a touch pad or a charger) at least 1 mm and less than 10 cm from said plate (this distance being measured perpendicular to said face and between said face and the end closest to the considered element) and can be activated at a second position of the support (Figure 3), in which the whole support is moved both horizontally over a distance of at least 50 cm, and vertically over a distance of at least 2 mm, preferably at least 1 cm with respect to the plate, and the elements (8) are deactivated and accessible, the elements having been deactivated during the travel of the plate by a safety device (not represented but lying, for example at the rear of the drawer or support), for example by the action of a circuit breaker and / or by the defusing of a contactor.
    When the drawer is pushed back, the support in the lower position gradually returns to the upper position inside the cabinet and when the drawer reaches its abutment in its initial position, a locking system (not shown) can block the assembly in its operating position and the switch, for example, can ensure the operation of the elements on the plate by the supply of electric current, said contactor being activated only when the front of the drawer is in contact with the furniture (or the support is in its first position).
    In the embodiment shown in FIG. 4, the piece of furniture (1) is also formed as before of a box (2) similar to that of the preceding figures, also surmounted by a work plane (3) entirely formed of a monolithic substrate (4) glass-ceramic as previously, and provided with heating elements (8) such as inductors, arranged under the plate, for cooking food, the location of the heating elements being indicated by decorations (9 ) on the upper face of the plate, the cabinet being this time provided with two doors (7 ') and a support, carrying at least the aforementioned heating elements, mobile, this time in rotation, for example around its edge ( 14) opposite to that (15) intended to be spaced from the plate and by which is provided the access of an operator to the elements on the support (as shown), or locally around an appropriate axis, to the way for example of a hatch under the plate.
    The support can be locked in its first position, where the elements on the support are opposite the lower face of the plate and, for at least some of them (for example the heating elements), against said plate / to a zero distance from said plate, or if necessary for others (for example a touch pad (17) or a charger) at least 1 mm and less than 10 cm from said plate, by means of latch (s) ) (or locking system (s)) holding said support against the plate. By opening the cabinet doors and removing the latch (s), the bracket then swings (as indicated by the arrow) downward and moves to a second position (shown in Figure 4) where the end (15) ) of the support is displaced (essentially vertically) over a distance of 20 cm (and with a rotation angle of 20 °), and the elements (8) are deactivated and accessible, these elements being for example deactivated during unlocking and movement of the support by defusing a contactor (not shown). If necessary the support can also be provided with a stand (16) (additional security system) allowing the need to maintain the support in its second position.
    The support may also comprise other elements, such as a touch screen or a tablet (17), these elements may also be deactivated during the switchover of the support or not.
    The furniture shown in the previous figures can be used for different purposes, such as writing, the support of objects, use as a kitchen table (allowing for example to eat or deposit cooking containers if necessary hot, etc.) etc. If necessary, the box can also be replaced by support legs (the equipment under the worktop can be hidden by a formwork located a few centimeters thick under the plate) in the image of a table. The equipment according to the invention can in particular be used with advantages to achieve a new range of multi-purpose furniture easier to repair despite the appropriate size and weight of some of their components.
