Description

REVERSIBLE HANGING DEVICE

  The present invention relates to a reversible attachment device comprising a removable support element that does not require mechanical attachment to the wall.

  Wall hangers are traditionally fastened using studded or screwed elements which are difficult to remove and which damage the walls significantly because of the perforations they cause. These are fixed systems that, once attached to the wall, limit the placement possibilities of hanging parts such as shelves or frames.

  There are also known wall hanging devices whose fixing is provided by adhesives or suction cups. However, these devices have a resistance to tearing too weak to withstand heavy loads, especially when you want to carry loads at a distance from the vertical surface of the wall and where there is therefore a lever between the point of attachment of the adhesive or the suction cup and the load to bear as is often the case with shelves or clothes racks by

example.

  Magnet fixation tests have also been carried out but these suffer the same disadvantages as adhesives and other suction cups. In addition, magnets tend to slide on a vertical wall when subjected to a force having a vertical component so that their attractive force can not be used properly.

  The present invention aims to provide an attachment device that overcomes the disadvantages of existing devices and allow the wall attachment of support elements such as shelves and racks having a large lever arm relative to the attachment points on the wall , or more generally the fixing surface, without risk of tearing, sliding or tilting of said elements.

  The invention also aims at providing a hooking device which makes it possible to detach and move as often as necessary a said support element hooked on a wall by said device to position it at a specific location chosen by the user by simple put in contact.

  The invention also aims to provide a reversible attachment device that allows the support and exposure of objects of all kinds on support elements hung on a vertical surface but without direct support on the ground or against a wall .

  The invention achieves its goals through a reversible attachment device comprising: at least one metal plate (3) adapted to be affixed and / or fixed on said vertical surface; at least one removable support element (4) comprising: a plating face (41) against said metal plate, and at least one object support means (42) integral with said plating face, preferably one straight or planar support means forming an angle between 0 and 180 with respect to a plane containing said plating face; and an interfacial structure (5) between said metal plate (3) and said plating face (41) of said support member (4) comprising: at least one magnet (51) whose tear resistance is at least equal to the maximum load of said objects to be supported on said support means (42) of the support member (4); and o at least one additional blocking means (52) of the support element (4) on said metal plate (3) located under said magnet (s), said interfacial structure (5) being secured to said plating face 41) of the support member and adapted to hold it in position against said metal plate (3) under the action of a said load applied to said support member (4).

  Here, a support element is understood to mean a part adapted to support or suspend any type of object along a vertical surface, preferably a flat surface (wall, board, panel) comprising at least one planar face allowing said element to be veneered against a metal plate affixed to said vertical surface to fix it by adhesion by means of magnets and at least one part forming a support means for said objects such as a tablet or a rod oriented in a secant direction relative to the plane containing said plating face of the support member.

  An interfacial structure is also understood to mean an arrangement of individual elements fixed or to be fixed to the plating face of the support element of the device and comprising at least one magnet enabling adhesion and fixing of the support element against a metal plate affixed to a said vertical surface and at least one locking means adapted to increase the adhesion of the support member on said plate and prevent slipping thereof.

  The number of magnets and locking means may vary depending on the surface of the plating face of the support member, the weight thereof and the objects to be supported by him, as well as the existing lever arm between the plating face and the free end of said support means of the support member.

  Of course, the metal plate intended to be fixed on a vertical surface, will be made of a material or a metal alloy having good magnetic properties to allow good adhesion or magnets of the interfacial structure of the device.

  The attachment device according to the invention is particularly advantageous in that it allows to hang on a vertical surface such as that of a wall a support element such as a shelf or a suspension rod without having to perforate said vertical surface, which avoids damaging it, and without using special tools once the metal plate is installed against said vertical surface.

  In addition, the device of the invention allows a complete modularity of installation since it is possible to unhook and reposition said support element at will against the metal plate thanks to the combined action of (the) magnet (s) and means (s) for blocking the interfacial structure that allow the reversible attachment of the support member of the device against the metal plate.

  Indeed, when the said magnet (s) and the said means (s) locking are in plane support against the said metal plate, they prevent any movement, including any sliding or tearing of the support member relative to said plate. To unhook said support member is then sufficient to manually exert an upward force on said support member so as to lift and rotate about an axis coplanar with said metal plate and virtually through the (s) said magnet (s) to unhook the support member.

  In addition, the interfacial structure of the device, consisting of at least one magnet and at least one locking means capable of increasing the adhesion between the plating face of the support element and the metal plate of the device, allows to increase the maximum distance (the lever arm) at which a load can be carried on said support member without stalling it with respect to said metal surface. Such an interfacial structure thus makes it possible to fix stably on a said metal plate a shelf supporting a load of at least 15 kg, and up to 50 kg in some cases depending on the number and power of the magnets and than the type of locking means chosen. The attachment device of the invention can thus be used to support heavy objects or heavy objects such as books or sculptures for example, and without the need to ensure the shelves or other support element directly in the wall by screws and other perforating systems.

  Advantageously, the metal plate of the attachment device according to the invention will have a thickness of between 0.5 mm and 3 cm. Thus, for the smallest thicknesses, the metal plate of the invention can be easily pressed against a wall or a panel, by gluing or screwing for example, in order to allow the reversible attachment of support elements of the device of the invention. invention on said wall or said panel.

  This is particularly useful for interior design of shops, individual house parts, or offices for example. In greater thicknesses the metal plate of the device can then form alone a self-supporting panel which, once wedged at its base or simply placed vertically in abutment against a wall, allows the reversible hooking of the support elements of the device. invention, the thickness of the plate being sufficient to avoid bending and / or buckling thereof. In such a configuration, it is then possible to use the device of the invention for space separation purposes, such as a screen or a movable partition, for exhibitions or again the arrangement of stores.

  According to another preferred feature of the invention, the magnet (s) of the interfacial structure of the device have a total tear resistance of at least 20 kg and are preferably multipole magnets, preferably Neodymium or Ferrite type. This advantageously makes it possible to increase the magnetic power of said magnet (s) and thus the resistance to significant loads on the support element of the device while limiting the surface and the volume of the magnets on the veneer face of said element. of support. Such multipole magnets are particularly advantageous for fixing support elements on metal plates of small thickness, that is to say of the order of 5 mm maximum.

  Moreover, irrespective of the type of magnet chosen, at least two magnets positioned at the same height on the plating face of the support element to be hooked and at least slightly separated from one another will preferably be used. other on the width of said veneer face. This disposition of the magnets advantageously makes it possible to increase the performance and the stability of the fastening on the metal plate, in particular to withstand the stresses tending to pivot the support element with respect to said metal plate.

  In a preferred embodiment of the invention, said means (s) for locking the interfacial structure of the device has a coefficient of friction at least equal to 0.10 on said metal plate, and preferably at least 0.15. Such a coefficient of friction of the interfacial structure blocking means advantageously makes it possible, in combination with the action of the magnet or magnets of said structure, to ensure perfect adhesion of the support element of the device against the metal wall and thus to prevent any slipping or receding thereof.

  Preferably, said blocking medium (s) may in particular be a friction-locking means constituted by a material based on synthetic or natural rubber and its derivatives, or in a variant embodiment. by an adhesion means comprising at least one other magnet or at least one suction system.

  Whatever the locking means chosen, it plays a very important role as to the safety of the attachment of the support element of the device.

BOY WUT

  According to another preferred embodiment, the metal plate of the device may advantageously comprise a coating having a thickness of at most 3 mm, and preferably a thickness of between 0.5 and 1.5 mm. Such a coating, consisting for example of wood, plastic or textile material or paint allows if necessary to adapt the metal plate to the aesthetics of the place in which the attachment device is used without affecting the performance of attachment of the support member.

  In a particular embodiment, the interfacial structure of the attachment device comprises a frame formed of U-section profiles, said magnets and said locking means being housed in said profiles between the lateral branches of the U so that their contact surface with said metal plate of the device is located in a plane substantially parallel to the plane of said plating face of said support member of the device.

  The arrangement of the different elements constituting the interfacial structure makes it possible to increase the stability of the support element on the metal plate. In addition, the housing of the magnets between the branches of the U defined by the profile section increases the attraction force of said magnets.

  In this embodiment, said frame may also comprise, advantageously, bores pierced in said profiles, preferably in the sidewall constituting the base of the U defined by the section of said profiles, said bores being intended to allow the attachment of the frame against the plating face of a said or said support member (s). Alternatively, said frame may also be in this embodiment the plating face of one or more support members, which will then consist of rods inserted by force or by screwing for example in said bores of the frame.

  Similarly in this embodiment, the said means (s) locking (s) may consist of adhesive material strips located between the magnets, substantially in the same plane as said magnets, the material of said strips can be flexible in order to provide a damping effect between the plating face of the support member and the metal plate, in which case the contact surface of said strips is preferably located in a plane substantially above the plane of the contact surface of the magnets.

  The device according to the invention thus makes it possible to reversibly hang any type of support element on a vertical surface, in particular on a wall or a panel and in a minimum of time and operations. It suffices in a first step to affix and / or fix on a said vertical surface a metal plate; then, in a second time to secure to a so-called plating face of a said support member an interfacial structure comprising at least one magnet and at least one locking means against said metal plate.

  Once this is achieved, it remains only to place said support member in a specific position on the metal plate by apposition of its said plating face against said metal plate so as to adhere thereto (s) said magnet (s) and the said means (s) blocking said interfacial structure and thus hooking said support member against said plate.

  Other features and advantages of the present invention will become apparent on reading the following detailed description, given in a nonlimiting manner and with reference to the appended drawings in which: FIG. 1 is an exploded view of the device of the invention; invention in a first embodiment: - Figure 2 is a sectional view along II of the device of Figure 1 in the position of use on a vertical wall wall.

  FIG. 3 represents the interfacial structure of the device of the invention in a back view in a second embodiment; FIG 3A is a sectional view along A-A of Figure 3; FIG. 4 represents a sectional view of the device of the invention in the position of use and comprising an interfacial structure as shown in FIG. 3. FIGS. 1 and 2 show the reversible coupling device 1 of the invention. in a first embodiment. It consists essentially of a metal plate 3, in particular made of steel, a support element 4 in the form of a shelf, which can be made of any metallic and / or plastic material and / or of wood and having a horizontal tablet 42, and finally an interfacial structure 5, consisting of two magnets 51 and two locking means 52 interposed between the plating face 41 of the shelf 4 and the metal plate 3.

  Said metal plate 3 is preferably able to be affixed and / or fixed, by gluing, nailing, screwing or plating, for example, on a vertical wall 2 of a wall or panel. For this purpose, it preferably has a thickness of the order of 0.5 mm to 1 cm maximum. In higher thicknesses, in particular of the order of 1 to 3 cm, said plate 3 can also constitute a self-supporting panel which, when wedged at its base, makes it possible to hang the shelf 4 on its surface via the interfacial structure 5.

  This interfacial structure 5 advantageously provides an intensive and non-destructive connection of the shelf 4 to the plate 3 to allow it to be attached to the latter in any desired position without tools or fixing materials. The interfacial structure 5 advantageously comprises a pair of magnets 51 and a pair of locking means 52 respectively fixed to the upper corners and to the lower corners of the plating face 41 of the shelf 4, this arrangement being optimal in terms of stability and resistance of the attachment to the metal plate 3, whether it is in traction parallel or orthogonal to the wall or in vertical pivoting on the wall.

  The magnets 51 and the locking means 52 of each pair are preferably identical. The magnets used in the device 1 may advantageously be of the Neodymium or Ferrite type, as well as multipolar or not, depending on the loads to be borne on the shelf and the lever arm formed by the tablet 42 thereof relative to the surface of the metal plate 3.

  The locking means 52 are in turn adhesion means which guarantee the stability of the shelf and make it possible to increase the resistance of the magnets 51 to sliding under the loads applied to said support elements 4. For this purpose, the locking means have a coefficient of friction t of at least between 0.10 and 0.15 on the steel, and their cumulative surface area on the plating face of the support elements 4 to hang is at least equal to that of the magnets 51. They should also be placed below the magnets 51, preferably near the edge or lower ends of the support member 4 to increase the slip resistance effect they provide.

  Different types of blocking means 52 may also be used. In particular, it is possible to choose as locking means for venting systems, materials based on natural or synthetic rubber, such as neoprene, and / or their derivatives, magnets whose attraction force will be less than that of magnets. fastening 51, or any other suitable material. These blocking means must of course in no way damage the metal support 3. They are chosen according to the characteristics of the support elements 4 to hang and airnants 51 used so that the sliding limit LG of the assembly constituted by the interfacial structure 5 and the support element 4 is reached before the step recess LD, that is to say the force at which the magnets 51 unhook from the metal plate under the action of a load applied to a determined distance from said plate 3 of the magnets 51 is not reached.

  In the embodiment illustrated in FIGS. 1 and 2, tests carried out with two ferrite-type multipolar magnets 51 and two neoprene locking means 52 have made it possible to demonstrate that the LG slip limit of the assembly constituted by the interfacial structure 5 and the support element 4 is increased by a factor of 2 to 5 and the recess limit LD is increased by 5 to 10 by the use of said locking means 52 in combination with the magnets 51 relative to the magnets alone. Loads of 50 Kg and 25 Kg were thus supported respectively without sliding or recess on shelves 4 with a height of 30 cm comprising a shelf 42 of 40 cm, and a height equal to 20 cm with a shelf of 30 cm.

  Figures 3, 3A and 4 shows the reversible attachment device 1 of the invention in a second embodiment.

  According to FIG. 4, the reversible coupling device 1 comprises an interfacial structure 5, shown in plan in FIG. 3 and in section in FIG. 3A, comprising a frame 53 formed of U-section profiles 6 intended to be positioned. against a metal support 3 pressed against a wall 2 on which it is desired to hang support elements 4 such as rods or shims 4 fixed in force or by means of bolts 10 in bores 7 drilled on the posts and crosspieces of the frame 53 (FIGS. 3 and 4).

  Magnets 51 are attached to the upper and lower ends of the profiles 6 forming the frame members 53, between the branches of the U, so as to concentrate the force of the magnets to the metal support 3. The magnets 51 are thus regularly distributed on the structure interfacial to the four corners of it. However, the magnets 51 positioned at the bottom of the uprights 6 of the frame 53 are not strictly necessary to achieve a satisfactory attachment to the metal plate 3 because of the presence of locking means 52 also positioned between the legs of the U profiles 6 forming the amounts of the frame 53 and described below.

  In the embodiment of FIGS. 3 to 4, the blocking means 52 are constituted by neoprene strips 52 glued on cleats 9 fixed between the legs of the uprights 6 of the frame 53 and making it possible to limit the thickness of said neoprene strips. .

  Advantageously, the free contact surface of said strips 52 at rest (FIG. 3A) may be slightly protruding with respect to the free contact surface of the magnets in order to compensate for the crushing effect produced against the metal plate 3 when the frame 53 is pressed against it (Figure 4) under the weight of the load 8 and the attraction of the magnets, and thus ensure a good horizontality of the support elements 4 and ensure the proper operation of the assembly.

  The dimensions of the frame 53 as well as the power of the magnets 51 used determine the maximum authorized weight of the load 8 on the support elements 4 as well as the maximum distance of distance (lever arm) to the metal plate 3 to which the load 8 can be carried on the support element 4 without sliding or recess of the device 1 of the invention.

  According to variants of the embodiment of Figures 3, 3A and 4 may also have a frame 53 of different shape, geometric or not and made of non-metallic materials, including plastic, wood, or any other material. Likewise, the magnets 51 distributed at the corners of the structure may be in the overhang on the metal support side in order to guarantee an optimum contact surface on the metal plate 3.

  The attachment device of the invention is particularly simple and is advantageous to implement and is suitable for a large number of applications ranging from the layout and decoration of stores to those of individual houses and apartments, including exhibitions and shows of all kinds. In addition, it is also possible to use metal plates covered with a suitable coating which allows to adapt the device to any type of environment and thus melt it in the overall aesthetic of a room.

  The present invention has been described here in particular embodiments which are in no way limitative of the scope of the invention, which extends in particular to changes in shape and dimensions of the constituent elements of the described reversible fastening device which would appear trivial for those skilled in the art.
