Description

The present invention relates to a fastening device for panels (or facings) intended to be hooked (or suspended) to a support frame, as well as a modular partitioning comprising a support frame on which are mounted such panels incorporating these devices. hanging. Modular exhibition systems are used by commercial or industrial companies, but also public services, in the context of participation in commercial event events (exhibition stands) or cultural events (temporary exhibitions in museums), but also in the layout of commercial spaces such as show room. For this purpose, these partitions require rapid assembly and disassembly while ensuring great transport convenience preserving the facilities and facilitating their handling between each new event. The partitions comprise a support structure on which panels are hung. The panels form a siding or a covering on which are generally arranged advertising or information media.

It is therefore important to preserve the state of these panels between each partition assembly. The existing panels include hooking devices of the panel on the structure of the partitioning ensuring them good support. However, these devices have the following drawbacks.

The first disadvantage relates to the risk of degradation of the surface of a panel during the handling and transport of the panels. Indeed, during the transport of the panels, they are leaning against each other, which causes contact between the attachment device of a panel with a surface of the adjacent panel, such contact may lead to deterioration the surface of the panel or a break of the fastening device rendering the panel unusable. The second disadvantage concerns the packaging of the panels during their transport. Indeed, as seen above the panels are backed to each other during transport. However, the presence of attachment devices between the panels causes a significant amount of space and prevents the realization of a stable stack of panels. These two disadvantages are well known to movers and handlers who to limit the risk of scratching the surface of a panel have side by side and on edge the surface of two panels on which are not arranged the shackles, which allows to preserve the state of these surfaces. The present invention aims to solve all or part of the disadvantages mentioned above.

For this purpose, the subject of the present invention is an attachment device for a panel intended to be hung on a support, characterized in that it comprises a first part intended to be received in a housing formed in one face of the panel of to be recessed or flush with said panel face, a second part forming a projection relative to the face of the panel and comprising hooking means on the support, and means for fixing the second part to the first part arranged to allow a removable attachment These arrangements make it possible to have panels that do not have elements protruding from its surfaces during their transport and thus make it possible to condition the panels on one another flat or against each other on edge without risk of scratching the surfaces of one of the panels or breaking a hanging device, and while limiting the space generated by the panel assembly x. According to one embodiment, the fixing means comprise a mortise integral with the first part intended to receive a tenon integral with the second part. This arrangement allows to nest the second part on the first to facilitate their joining. According to the same embodiment, the mortise of the first portion has a shape allowing insertion or removal of the tenon in the mortise according to a first relative position of the tenon relative to the mortise, and a locking of the tenon in the mortise according to a second relative position of the tenon relative to the mortise. This arrangement makes it possible to ensure a prior maintenance without resorting to any tool.

According to one embodiment, the tenon arranged on the second part comprises at least one narrowing intended to cooperate with an edge of the mortise to ensure the locking of the tenon in the mortise. This narrowing may also have beveled edges to press the first portion against the second when the latter is brought into the locking position. Advantageously, the fixing means are arranged to allow the passage of the first insertion or withdrawal position to the second locking position by a relative rotational movement of the first part relative to the second part. The rotational movement facilitates the operator to move from one position to another thanks to the larger lever obtained by the shape of the first part of the device, which is not the case in one embodiment. where the first part is made mobile in translation relative to the second. According to the same embodiment, the first insertion or withdrawal position and the second locking position are separated by an angle of between 1 ° and 90 °, and preferably equal to 90 °. This arrangement allows the operator to easily locate the insertion and removal positions of the first part relative to the second. According to one embodiment, the fixing means comprise a securing screw of the first part to the second part. It makes it possible to fix immovably the second part of the attachment device on the first. Advantageously, the attachment means comprise a portion of the second portion forming a finger for holding the panel on the support. The geometrical shape of the second part is thus provided so that it allows the hooking of the panel directly on a support disposed properly on the structure without having to resort to other additional parts. According to one embodiment, the first part is fixed in the housing of the panel by screwing. The first part remains at all times confined in the housing of the panel intended to accommodate it and no longer requires disassembly after being mounted a first time. A screw fixing ensures the function of maintaining the first part inside the panel housing perfectly. Finally, the first part has a shape complementary to that of the panel housing.

Thus, when the panel is mounted on the partition structure, the force exerted on the fastening screws of the first part of the attachment device is reduced and the successive actions of installation and removal of the panels on the structure do not engender no play around the threads of the screws.

The present invention also relates to a modular partition comprising a support frame, a panel to be attached to the support frame and at least one attachment device of the panel on the support frame according to the device shown above. Advantageously, the support frame comprises at least one fitting comprising a hooking element intended to cooperate with the hooking means of the hooking device. According to the same embodiment, the fastening element of the support comprises hooking means complementary to those of the hooking device of the panel in at least two locations.

In any case, the invention will be better understood from the description which follows, with reference to the appended diagrammatic drawings showing, by way of non-limiting examples, the attachment device and a partitioning with fitted panels. of an attachment device according to the invention.

FIG. 1 represents an exploded view of the device according to the invention as well as a partial view of the panel in which the device is mounted. Figure 2a shows a perspective view of the first part of the device according to the invention.

Figure 2b shows a perspective view of the second part of the device according to the invention. Figures 3 to 9 show respectively the successive mounting steps of mounting the device on a panel. Figure 10 shows the detail of a fitting to be attached to the frame of the partition.

Figure 11 shows the structure of a partition equipped with panels with fastening devices according to the invention. According to FIGS. 1, 2a and 2b, an attachment device 1 according to the invention comprises a first part 2, a second part 3 and a housing 10 formed transversely in the thickness of a panel 11. According to FIG. As shown, the first part 2 comprises two planar bases 4, 5 with a geometric ring shape or two-ray basket handle separated by a predetermined height defining its thickness. The lower base 4 comprises a housing 6 of rectangular shape opening to an opening 7b of smaller dimensions also of rectangular shape disposed on the surface of the upper base 5 of the first part 2 of the attachment device 1. The first part 2 of the 1 attachment device also comprises two holes 8a, drilled obliquely from the surface of the two ends of the upper base 5 of the first portion 2 of the attachment device 1 and opening into the thickness of the first portion 2. These two holes 8a each have a countersink 8c for receiving the heads of two holding screws 8b. Once in place in their orifice 8a, these two screws 8b protrude from the edges of the first part 2 of the attachment device 1 while their heads remain confined within each of the milling 8c. A third through-hole 9a located between the opening 7b and the countersink 8c of one of the orifices 8a is arranged transversely between the upper base 5 and the lower base 4 of the first part 2 of the attachment device 1. The housing 10 Milled transversely in the panel 11 has in the illustrated example a depth substantially equal to the thickness of the first portion 2 of the attachment device. It also has a shape complementary to that of the first part 2 of the attachment device 1. However, it is obvious that the attachment device 1 according to the invention is not limited to a substantially equal housing depth. to that of the first part 2 and to a complementary form of this part 2.

It is important to remain within the scope of the invention that this depth is at least equal to the thickness of the first part 2 of the attachment device 1, but it may however be greater. Similarly, the complementary shape of the housing 10 is only a characteristic according to a preferred embodiment, the absence of which can not reduce the scope of the invention. The second part 3 of the attachment device 1 according to the invention has a substantially rectangular shape with an upper part 12 comprising the hooking means of the second part 3 to the first part 2 and a lower part 13 comprising the finger of attachment of the device 1 to a fitting 21. The upper part 12 of the second part 3 of the device 1 comprises a flat lower surface 14 and a pin 7a, of a shape substantially complementary to that of the opening 7b which is then comparable to a mortise 7b, and protruding transversely to this same flat surface. This complementarity of form allows the commitment of one party in the other as well as their mutual maintenance. This post 7a is connected to the lower flat surface 14 of the upper part 12 of the device 1 by a foot resulting from the recess 7c resulting from the longitudinal machining to the lower flat surface 14 over the entire contour of the pin 7a. In the example shown, the foot of the pin 7a has a substantially rectangular shape in a transverse sectional plane but it is understood that it can have any shape.

In all cases, the maximum dimension of the foot taken longitudinally at the lower planar surface 14 of the upper part 12 of the second part 3 of the device 1 must be at most equal to the smallest dimension of the mortise 7b taken on a parallel plane at the upper base 5 of the first part 2 of the device 1.

The profile of the second portion 3 of the device 1 has a first portion 15 with a substantially trapezoidal shape extended by a second portion 16 projecting from the large base of the trapezium of the first portion 15. This portion 16 projecting reveals a shoulder 17 turned transversely to the lower planar surface 14 of the upper portion 12 of the second portion 3 and has a narrowing of its thickness from the first portion 15 of the profile to its end. The corners delimiting the end of this portion 16 are bevelled. The upper portion 12 of the second portion 3 of the device 1 has on its upper face a transverse milling at the lower portion 13 of the second portion 3 of the device 1 showing a housing 18, two of whose edges are delimited by the side walls forming the trapezoidal profile of the first portion 15 of the second portion 3 of the device 1. This milling stops shortly before the shoulder 17 and is necessary only to the extent that it is intended to use a screw 9b to immobilize the second part 3 with respect to the first part 2. The bottom 19 of this housing 18 is in turn substantially parallel to the lower flat surface 14 of the upper part 12 of the second part of the device 1 and comprises a hole 9a 'crossing and transverse at the bottom 19 of the dwelling 18.

This orifice 9a 'has a countersink 9c and coincides with the orifice 9a pierced transversely in the first part 2 of the attachment device 1 when the two parts are secured to one another by the tenon couple 7a and mortise 7b. The lower part 13 of the second part 3 of the device 1 is provided with a finger-shaped profile surface 16 resulting from the shoulder 17. During a first mounting of the attachment device 1 illustrated in FIGS. 3 to 9 , the operator preparing the panels 11 having housings 10 adapted to receive the first parts 2 of the attachment devices 1 according to the invention begins by inserting in these housings 10 the first parts 2 of the attachment devices 1 in the right insertion direction, that is to say by directing the lower base 4 towards the bottom of the housing 10 panels 11. The following steps are given by way of example for a single attachment device 1, but it It is obvious that they apply to all 30 of the attachment devices 1 disposed on the panel 11. The first part 2 of the attachment device 1 according to the invention is permanently fixed to the panel 11 with the aid of two screws 8b screwed into the thickness of the wooden panel 11 with a screwdriver. It is obvious that the attachment device 1 according to the invention is not limited to this type of fastening and to this type of panel 11, often made of agglomerated wood, but to any type of panel capable of receiving the part 2 in a housing 10. The first part 2 of the attachment device 1 can also be glued or fixed by means of rail-type fastening inside a larger housing. The second part 3 of the attachment device 1 is then engaged in the first part 2 thanks to the complementarity of the tenon couple 7a and mortise 7b. To this end, the second part 3 of the attachment device 1 is disposed at an angle substantially equal to 90 ° with respect to its alignment position with the first part 2 in order to align the pin 7a with the mortise 7b according to a direction allowing him to cross it.

After inserting the pin 7a in the mortise 7b, the fitter then rotates the second portion 3 by about 90 ° with respect to the first portion 2 of the device to coincide the orifice 9a 'disposed on the second part 3 with the orifice 9a disposed on the first part 2. In addition, in order to secure the two parts 2, 3 of the device 1, a screw 9b (optional) is screwed with a screwdriver through the orifices 9a. and 9a '. In this position, there appears an open housing 22 formed by on the one hand the second portion 16 of the profile of the second part 3 of the device 1 as well as the shoulder 17 and on the other hand by a portion of the upper base 5 of the first part 2 of the device 1. At this stage, the panel is ready to be positioned on a fitting 21 disposed on a member of the support frame 20. As illustrated in Figure 10, the fitting 21 comprises at least one portion 23 extending transversely from the ends of the front face 25 of a plate 24. In the example illustrated, the rear face 26 has in turn four portions 28a projecting from the same rear face 26 of the plate 24. These four portions 28a comprise a transverse narrowing forming a shoulder 29 adjoining the rear face 26 of the plate 24. When mounting the fitting 21 on the support 27, these four portions 28a are inserted into grooves 28b formed on 27. The fittings 21 may be inserted at any point in the grooves 28b of the support 27 through an inlet slot 30 of a width slightly greater than that of the portions 28a, in a perpendicular and then tangential movement to the support. 27, without having to slide them from one end of the support 27.

A transverse orifice 31 is arranged through the plate 24. This orifice 31 has a thread and is intended to receive a screw 32 which after passing through the thread, sees its end come to bear against the support 27, which causes the maintaining the fitting 21 on the latter according to a desired height. Once the fittings 21 set up according to the desired height, the open housing 22 and the finger 16 serve to hold the panel 11 on a portion 23 of the fitting 21 which can be inserted in this housing 22. The panel 11 therefore holds by gravity by its own weight on the portions 23 of fittings 21 able to retain it.

As illustrated in FIG. 11, the assembler can thus cover all of the internal and external contours of the partition structure 20 using panels 11 equipped with devices 1 according to the invention. When disassembling the partition 20, each of the panels 11 is removed by making upward movement clean to release the portions 23 of the bracket holding the panel 11 in the housing 22. In the case where the screws 9b have been put in place , the fitter then unscrews each of the screws 9b of each of the attachment devices 1 arranged on each of the panels 11, then removes all the second parts 3 of the devices. It is not necessary to remove the first parts 2 of their housing 6. Each of the panels 11 is thus found without any projecting part on any of its surfaces and can thus be transported without risk of deterioration.

When reassembling the partition 20, the fitter must reinstall the second parts 3 of the attachment device 1 on the first parts 2 and fix them with the optional screws 9b. As goes without saying, the invention is not limited to the embodiments of this attachment device 1, described above as an example, but it encompasses all the variants such as for example a nesting by translation of the second portion 3 of the device 1 on the first part 2 instead of rotational interlocking as described above.
