Domaine technique de l'invention

[0001] The invention relates to a device for fixing a vertical cladding panel, in particular a glass panel, onto a structure, the fixing device comprising: a cross member intended to be fixed to the structure and having a hooking edge; a hook intended to be hooked to the cross member by a first approach movement during which the hook is brought forward to the cross member, longitudinally towards the rear, above the edge, and then by a second hooking movement by sliding vertically downwards in a hooking direction, the hook having means for fixing on a rear face of the panel; means for locking the hook in sliding upwards in a hooking direction when it is hooked to the cross member. Arrière-plan technique

[0002] It is known to fix a vertical transverse cladding panel onto a structure using a fixing device.

[0003] As is known, the fixing device consists of a support that is fixed to the structure and a hook that is fixed to the panel. The hook is attached to the support in order to position the panel on the structure.

[0004] To prevent the panels from coming loose, solutions are known by tightening the hook against the support, for example by inserting wedges using a hammer or by longitudinally tightening a notched plate against a vertical face of the hook.

[0005] These solutions are unsatisfactory because they require the locking element to be sufficiently tightened against the hook. Without sufficient tightening, the panel risks detaching. Furthermore, these solutions necessitate the use of tools on the back of the panel after installation, often blindly, under very limited accessibility conditions.

[0006] Therefore, there is a need to find a fixing solution that prevents a vertical transverse panel from detaching from its fixing structure, and that is easy and quick to assemble.

[0007] For example, EP3405625, CH659679 and EP1878847 are known to be tedious to install and tighten sufficiently to ensure long-term stability. Résumé de l'invention

[0008] The invention proposes a device for fixing a vertical cladding panel, in particular a glass panel, comprising: a cross member having a hooking edge; a hook intended to be hooked to the cross member by a first approach movement during which the hook is brought forward to the cross member longitudinally towards the rear, above the edge, and then by a second hooking movement by sliding vertically downwards in a hooking direction, the hook having means for fixing on a rear face of the panel; means for locking the hook in sliding upwards in a hooking direction when it is hooked to the cross member.

[0009] The fastening device according to the invention is characterized in that the locking means comprise a locking element which is movably mounted on a body of the hook between: a release position towards which it is pushed longitudinally backwards automatically by contact with the cross member during the approach movement; a locking position towards which it is elastically pulled forwards and in which the locking element is intended to be engaged below a stop face of the cross member at the end of the hooking movement to prevent the hook from unhooking.

[0010] According to another aspect of the fastening device of the invention, the locking element is pivotally mounted on the hook by means of an elastic return member, the locking element being clamped vertically against the stop face when the hook is mounted on the cross member.

[0011] According to another aspect of the fastening device of the invention, the elastic return member is formed by an asymmetric wire spring having two legs of different lengths, each of which has a connecting end with the locking element and a free end mounted pivotally about a transverse pivot axis in the body of the hook, the pivot axes of each leg being distinct.

[0012] According to another aspect of the fastening device of the invention, the locking element is formed by the bent section of a spring wire, two end sections of which form the two legs of the elastic return member.

[0013] According to another aspect of the fastening device of the invention, the elastic return element includes a push button which is accessible to a user's finger when the hook is attached to the crossbar and which allows, by lever action, the locking element to be manually moved towards its release position against the elastic return force.

[0014] According to another aspect of the fastening device of the invention, the pusher is formed by a section of the spring wire constituting the locking element.

[0015] According to another aspect of the fastening device of the invention, the means for fastening the hook to the panel comprise a contact flange with the panel which is linked to the body of the hook with an angular deflection around a longitudinal axis.

[0016] According to another aspect of the fixing device of the invention, the flange is mounted in the body of the hook by means of a cylindrical spacer with a longitudinal axis received pivotally in an orifice of the hook, a pin being fixed across the spacer through a light in the body opening transversely into the orifice, two opposite edges of the light defining travel stops by contact with the pin when pivoting the flange.

[0017] According to another aspect of the fastening device of the invention, it includes a rider to immobilize the hook transversely with respect to the crossbar, the rider being intended to be fixed at least transversely on the crossbar.

[0018] The invention also proposes an assembly comprising a cladding panel, and at least one fixing device made according to the teachings of the invention which includes at least two hooks which are arranged along an upper edge of the panel, against a rear face of the panel, the two hooks being intended to be hooked to the same cross member.

[0019] According to another aspect of the assembly made according to the teachings of the invention, only one of the hooks of the fastening device has a rider to immobilize the hook transversely with respect to the cross member, the other of said hooks being configured to be hooked to the associated cross member free to slide in a transverse direction.

Description détaillée de l'invention

[0021] In the following description, elements with an identical structure or analogous functions will be designated by the same reference.

[0022] In the following description, we will adopt, as a non-limiting example, a longitudinal orientation "L", directed orthogonally to the plane of the panel, from back to front, a vertical orientation "V" directed from top to bottom and a transverse orientation "T" directed from left to right.

[0023] The vertical orientation "V" is here directed globally according to the direction of Earth's gravity.

[0024] We represented at the figure 1 a vertical structure 10 onto which cladding panels 12 are fixed.

[0025] The vertical structure 10 is formed here by vertical uprights 14 arranged parallel to each other at a distance in a transverse direction. The uprights 14 are, for example, fixed to a wall such as a building facade or an exterior wall. The uprights can be fixed either in contact with the wall or at a distance from the wall.

[0026] Alternatively, the structure is formed directly by a wall such as a facade or an exterior wall.

[0027] As represented in figures 2 And 3Each cladding panel 12 here has a rectangular shape. These are, for example, glass panels. The glass panel may optionally incorporate photovoltaic cells to form a solar panel. Each cladding panel 12 extends in a vertical transverse plane. Each cladding panel 12 is delimited longitudinally by a rear face 16, facing the structure 10, and a front face 18 opposite the rear face 16. These are large cladding panels 12, for example, more than 1 m high. Such cladding panels 12 also have a very significant weight, for example, on the order of 300 kg.

[0028] Each cladding panel 12 is fixed to the structure 10 by means of at least one fixing device 20.

[0029] As depicted in the figure 4 , such a fixing device 20 comprises a cross member 22 intended to be fixed to the structure 10. The cross member 22 extends along a main transverse axis perpendicular to the uprights 14. The cross member 22 is fixed to at least two uprights 14 by two free end sections so as to extend transversely between the two uprights 14.

[0030] Because of the presence of these uprights 14, it is possible to interpose a layer of insulating material (not shown) between the crossbeams 22 and the wall to which the uprights 14 are fixed.

[0031] Alternatively, when the structure is formed by a wall, the crossbeams 22 are fixed directly in contact with the wall.

[0032] The cross members 22 are arranged here in vertical columns. When all the cladding panels 12 are to be aligned transversely, the cross members 22 of two adjacent columns are aligned transversely. Conversely, when the panels are to be staggered, the cross members 22 of one column are offset vertically relative to the cross members 22 of the adjacent columns.

[0033] Cross member 22 is in the form of a profile whose cross-section is shown in detail in figures 3 And 5 The cross member 22 thus has a base 24 in the form of a vertical plate. The base 24 has a rear face which is intended to be supported against the structure 10, here formed by the uprights 14, to allow its fixing, for example by screwing.

[0034] The cross-section of the cross member 22 also includes a web 26 which projects longitudinally from a front face of the flange 24. A flange 28 extends vertically upwards from a front end edge of the web 26. The flange 28 is delimited upwards by a free end edge 30. The free end edge 30 will be referred to hereafter as the "hook edge 30".

[0035] Wing 28, core 26 and sole 24 define a groove 32 open upwards.

[0036] The fastening device 20 includes at least one hook 34. The fastening device 20 here includes two hooks 34 which are arranged at two upper corners of the rear face 16 of the panel 12, as shown in the figure 2 Since the two brackets 34 are identical, only one of these brackets 34 will be described hereafter.

[0037] As represented in figures 6 And 7The hook 34 comprises a body 36 extending along a principal vertical direction. The body 36 has a front face 38 intended to be arranged opposite the rear face 16 of the panel 12, as illustrated in the figure 5 The body 36 also has a transverse vertical rear face 40. At its upper end, the body 36 has an arm 41 that extends longitudinally at a right angle towards the rear. A wing 42 extends vertically downwards from a rear end of the arm 41. A front face 44 of the wing 42 is positioned opposite the rear face 40 of the body 36. The wing 42, the body 36, and the arm 41 thus define the interior of the hook 34.

[0038] A free lower end of the wing 42 is situated above the level of the lower end of the body 36 so that a lower part of the rear face 40 of the body protrudes vertically downwards relative to the wing 42.

[0039] The hook 34 is thus intended to be hooked onto the cross member 22 by an initial approach movement during which the hook 34 is brought close to the cross member 22 by translation along a rearward longitudinal approach direction, moving from the position shown in figure 3 to the position represented in figure 8 During this approach movement, the lower end of the wing 42 passes over the attachment edge 30 of the cross member 22 until the wing 42 is aligned with the groove 32. In this position, the lower part of the rear face 40 of the body 36 abuts against the front face of the wing 28 of the cross member 22. Then, in a second attachment movement, the hook 34 is slid vertically downwards in a direction of attachment so that the wing 42 of the hook 34 is received in the groove 32, moving from the position shown to the figure 8 to the position indicated in the figure 5 The hooking movement continues until the arm 41 is in contact with the hooking edge 30 of the cross member 22 to suspend the panel 12. The hooking movement is guided by the sliding contact between the rear face 40 of the body 36 and the front face of the wing 28 of the cross member 22.

[0040] Furthermore, to ensure that the hooking edge 30 is properly received in the hook 34, between the wing 42 and the body 36, the wing 42 has a slightly rearward curved section at its lower end to form a guide ramp for the hooking edge 30. Similarly, the rear face 40 of the body 36 has a beveled lower end to guide the hooking edge 30 between the wing 42 and the body 36 of the hook 34.

[0041] Hook 34 also includes means for fixing to the rear face 16 of panel 12.

[0042] As a non-limiting example shown in the figure 9 In the embodiment shown in the figures, the means for fixing the hook 34 include a flange 46 in contact with the rear face 16 of the panel 12. The flange 46 is here in the form of a disc with a longitudinal axis, one front face of which is fitted with a pad 48, for example made of elastomer material, to avoid damaging the glass panel 12.

[0043] Advantageously, but not necessarily, the flange 46 is mounted in the body 36 of the hook 34 with angular deflection around its longitudinal axis. This allows, in particular, for compensation of any verticality defect in the cross member 22 in order to ensure that all the hooks 34 of the panel 12 are correctly attached to the cross member 22.

[0044] In the embodiment shown in figures 7 And 9The flange 46 is mounted in the body 36 of the hook 34 by means of a cylindrical spacer 50 with a longitudinal axis, which pivots about said axis in a complementaryly shaped opening that leads to the front face 38 of the body 36. The spacer 50 has a central rear end stud 51 for insertion into the corresponding opening in the body 36 to correctly position the spacer 50 in a longitudinal direction by abutting it against a shoulder face of the opening in the body 36. The body 36 has at least one slot 52 that opens transversely into one of its vertical lateral edges. The slot opens transversely into the opening in the body 36. The slot 52 has a vertically elongated oblong shape and is vertically bounded by two end edges, as is particularly visible in the figures 5 And 7 .

[0045] A pin 54 is fixed across the spacer 50 so that it protrudes through the associated slot 52 in the body 36. The pin 54 is thus pivotally fixed to the cylinder about its longitudinal axis. The two vertical end edges of the slot define travel stops by contacting the pin 54 when the flange 46 pivots relative to the hook 34.

[0046] As depicted in the figure 9 , the hook 34 is here fixed to the panel by means of a screw 55 which is intended to be screwed into a central thread (not shown) of the spacer 50 which opens into the front face of the flange 46.

[0047] According to the teachings of the invention, the hook 34 includes means for sliding upwards in a direction of release when it is attached to the cross member 22. The locking means comprise a locking element 56 which is movably mounted on the body 36 of the hook between: a release position towards which it is automatically pushed longitudinally backwards by contact with the cross member 22 during the approach movement, as shown in the figure 8 ; and a locking position towards which it is elastically pulled forward and in which the locking element 56 is intended to be engaged below a stop face 58 of the cross member 22 at the end of the hooking movement to prevent the hook 34 from unhooking, as shown in the figure 5 .

[0048] To allow the locking element 56 to be automatically pushed towards its release position, the locking element 56 is arranged to project rearward relative to the rear face 40 of the body 36 when it occupies its locking position, as shown in the figure 5 .

[0049] More specifically, the abutment face 58 is here formed by an inferior face of the web 26 of the cross member 22.

[0050] The locking element 56 is preferably arranged opposite the portion of the hook 34 which is pressed against the hooking edge 30, when the hook 34 is mounted on the cross member 34.

[0051] The locking element 56 is pivotally mounted on the body 36 of the hook 34 by means of an elastic return member 60, which provides the elastic return force to its locking position. This elastic return member 60 also allows the locking element 56 to be clamped vertically against the stop face 58 when the hook 34 is mounted on the cross member 22.

[0052] The locking element 56 is more specifically mounted to pivot about a generally transverse pivot axis which is located here above the locking element 56. In its release position, the locking element 56 is arranged below the body 36 of the hook so as to allow access from the edge 34 inside the hook 34, and in the locking position, the locking element 56 is located in front of the body 36 of the hook 34, above its release position.

[0053] In the locking position, the locking element 56 is more particularly arranged at the right of its pivot axis so that a vertical force applied to the locking element 56 does not cause any movement of the latter.

[0054] As represented in figures 6 And 7, the elastic return element 60 is here formed by an asymmetric wire spring having two legs 60A, 60B of different lengths, each of which has an end 62A, 62B of connection with the locking element 56 and a free end 64A, 64B mounted pivoting about a transverse pivoting axis "B1, B2" fixed in the body 36 of the hook 34. The connecting ends 62A, 62B of the legs 60A, 60B are arranged substantially at the same height.

[0055] The free end 64A, 64B of the legs 60A, 60B is for example bent orthogonally to the leg towards the body 36 to be inserted into corresponding holes.

[0056] Each leg 60A, 60B extends vertically when the locking element 56 is in its locking position. The connecting ends 62A, 62B form the lower ends of legs 60A, 60B, while the free ends 64A, 64B are the upper ends of legs 60A, 60B. The pivot axes "B1, B2" of each leg 60A, 60B are distinct. They are vertically offset due to the difference in length between the two legs 60A, 60B. The pivot axis of the locking element 56 is then located approximately between the two axes "B1, B2".

[0057] This offset of the pivot axes "B1, B2", combined with the elasticity of the wire, causes elastic bending of the tabs 60A, 60B when the locking element 56 is pushed towards its release position. The tabs 60A, 60B are then returned to their vertical position by their own elasticity.

[0058] In an alternative, not shown, variant of the invention, the elastic return element can also be implemented by other means. For example, the elastic return element is implemented using a torsion spring or a leaf spring with elastic flexibility.

[0059] The locking element 56 and the elastic return element 60 are advantageously made in one piece.

[0060] In the example shown in the figures, the locking element 56 is formed by the bent section of a spring wire, two end sections of which form the two tabs 60A, 60B of the elastic return member 60. The locking element 56 is, for example, made by bending the wire constituting each tab 60A, 60B backwards.

[0061] In certain cases, it can be advantageous to be able to easily detach the hook 34, for example, to replace a defective panel 12. For this purpose, the elastic return element 56 also includes a push button 66 which is accessible to a user's finger when the hook 34 is attached to the cross member 22. This push button 66 allows, by lever action, the locking element 56 to be manually moved to its release position against the elastic return force.

[0062] To increase the leverage effect, the pusher 66 is positioned below the locking element 56. The pusher 66 is specifically supported by the locking element 56, as shown in the diagram. figures 5 And 7 .

[0063] The pusher 66 is advantageously formed by a section of the spring wire constituting the locking element 56.

[0064] Thus, the elastic return element 60, the locking element 56, and the pusher 66 are all made by bending a single spring wire. The spring wire has two end sections forming the tabs 60A and 60B. One section is then bent backward at the base of the tabs 60A and 60B to form the locking element 56. A section of wire located behind the locking element 56 is bent forward beneath the locking element 56 to form the pusher 66.

[0065] To mount the panel 12 onto a structure 10, the cross member 22 is first fixed to the uprights 14, as shown in the figure 4 .

[0066] Then at least two hooks 34 are mounted near each upper corner of the panel 12. These two hooks 34 are intended to be hung on the same cross member 22.

[0067] Panel 12 is here pierced with two holes. Each hook 34 is arranged so that its flange 46 lies flat against the rear face 16 of panel 12, the central threaded hole coinciding with an associated hole in panel 12. The screw 55 is then inserted into the threaded hole through the hole. The head of the screw 55 is tightened against the front face 16 of panel 12, preferably with the interposition of a washer 68 to distribute the tightening forces around the entire circumference of the hole, as shown in the figure. figure 9 The two hooks 34 are thus fixed to panel 12.

[0068] As depicted in the figure 2 The lower corners of panel 12 are fitted with hooks 70 which have the same structure as the hooks 34 described previously, except that they do not have any means to prevent them from being detached. These hooks 70 are intended to be attached to a cross member 22 identical to that of the fastening device described previously.

[0069] During installation, panel 12 is positioned parallel to the crossbeams 22, at a distance from structure 10, as shown in the figure 3 Then the first approach movement is carried out along the approach direction until the rear face 40 of the body 36 of the hooks 34 is in contact with the front face of the wing 28 of the cross member 22, as shown in the figure 8 During this movement, a rear end of the locking element 56 comes to rest against the front face of the wing 28 of the cross member 22, which causes it to move backwards into its release position against the elastic return force of the elastic return member 60.

[0070] Then, during the hooking movement, the panel is slid downwards in the hooking direction. The hooks 34 then hook onto the hooking edge 30 of the cross member 22, as shown in the figure 5 The hooks 34 are then supported on the crossbar 22 against the weight of the panel 12.

[0071] In doing so, the locking element 56 also slides downwards and when it reaches below the web 26, it is elastically returned to its locking position in which it is clamped against the stop face 58, below the web 26.

[0072] When a release force is applied to the panel, the locking element 56 butts against the stop face 58 to prevent the panel 12 from moving. The release force is transmitted to the body 36 of the hook 34 via the vertical tabs 60A, 60B without causing any movement of the locking element 56.

[0073] The lower hooks 70 are also attached to their cross member 22 in the same way and in the same movement as the panel 12. However, the lower hooks 70 are not supported on their cross member 22 to allow for vertical expansion of the panel 22.

[0074] In this position, panel 12 is still likely to slide transversely in groove 32 of cross member 22.

[0075] To block this last degree of freedom of panel 12, a bracket 72 is provided, which is intended to be arranged on one of the upper hooks 34. The bracket 72 has two legs 74 connected by a transverse bridge 76. The two legs 74 are arranged transversely on either side of the hook 34, for example by interlocking vertically downwards.

[0076] The bracket 72 also includes means for being immobilized at least transversely with respect to the cross member 22.

[0077] According to a first embodiment of rider 72 represented in figures 10 And 11The immobilizing means consist of a plate 78 which is attached to the bracket 72. The plate 78 is, for example, made in one piece with the bracket 72. This plate 78 has a fixing hole 80 which is designed to be positioned against one face of the cross member 22 when the bracket 72 is fitted around the hook 34. The plate 78 is then fixed to the cross member by means of a screw (not shown) through the fixing hole 80. This arrangement prevents the lateral movement of the panel 12. In addition, the plate 78 is designed to extend beyond the edge of the panel 12 in a transverse direction to allow it to be fixed by screwing after the panel 12 has been installed.

[0078] According to a second embodiment of rider 72 represented in figures 12 And 13The immobilization means are pinching devices. The rider 72 is then equipped with two pairs of legs 74A, 74B on either side of the hook 34. Each pair comprises a front leg 74A and a rear leg 74B. The legs 74A, 74B of each pair are arranged longitudinally opposite each other and are elastically pulled towards each other along a longitudinal direction. Each leg 74A, 74B of a pair is equipped with at least one spur 82 which is directed towards the other leg 74A, 74B of the pair.

[0079] When the bracket 72 is fitted onto the hook 34, the rear leg 74B of each pair is received inside the groove 32, while the front leg 74A is received against the front face of the flange 28 of the cross member 22, outside the groove 32. The two legs 74A, 74B of each pair then grip the flange 28 of the cross member 22 so that their spurs 82 bite into the material constituting the cross member 22. The spurs 82 thus allow the bracket 72 to be fixed to the cross member 22.
