Description

The invention relates to the support of constituent parts of modular or removable elements whose framework is essentially formed of profiles arranged vertically, and more particularly the support of shelves or spacers of such elements when said framework comprises profiles having externally at least one groove in
T.

 The targeted field is therefore more particularly, but not exclusively, that of the assembly of furnishing elements in kit form, in particular of shelf elements to constitute display cases and / or storage elements.

 There are already many systems for supporting shelves or spacers in combination with vertical profiles.

 Various systems have been proposed associated with perforated sections, according to a rack system, with possibly cantilevered support angles.

 However, these systems are always limited to predetermined heights, for example defined by the pitch of the vertical rack, so that specialists have sought solutions for supporting a shelf or spacer at any height, chosen according to your needs of the cause.

 Different systems have thus been proposed, in combination with profiles with one or more longitudinal external grooves, and in particular profiles with T-grooves.

 It is indeed very advantageous to use hollow profiles, of quadrangular section with rounded angles, the faces of which have a T-shaped groove, because this type of profile, whether it is made of metal (in particular extruded aluminum) or of material plastic (especially polyvinyl chloride), allows many mounting possibilities.

 The systems used were then either of the expansion type, or of the single stop type.

 Support devices have thus been proposed comprising a deformable part, liable to undergo a radial expansion by operating a screw or bolt: after insertion of the deformable part into the T-groove, it was necessary to operate a tool (screwdriver or wrench) to deform the system and thus obtain a lock at the desired height.

 Similar systems have been proposed comprising a two-part cleat inserted in the groove, said parts being spaced from each other using a tool after insertion into the groove of the profile.

 Anyway, all these systems require the use of a tool (screwdriver or wrench), and their handling is not always easy, especially when there is little space.

 With regard to systems with a single stop, systems have been proposed comprising a counterplate and a yoke connected together by a threaded rod passing through said yoke which was internally tapped: the tightening still requires a tool, and moreover the manufacturing cost is relatively high, which practically limits the system to generally very expensive modular elements.

 Finally, it was proposed to use a rod which was inserted into the T-groove, after having cut it to the desired length.

 Such a system is certainly economical, but it has many practical drawbacks: it is necessary to accurately measure the length to be cut, possibly removing one or more rods when the tablet is wobbly to start the operation again, after which we put a cleat in each groove, until it rests on the end of the associated rod. It should be noted that this system absolutely requires having free access to the groove at the end of the profile in order to be able to thread the sectioned rods, then the cleats: however this access is not always available in the production of elements furniture kit.

 The object of the invention is therefore to provide a support device which does not require any particular tool for tightening to the desired height.

 The object of the invention is also to propose a support device which is simple and inexpensive in design, with a minimum of constituent parts.

 The object of the invention is also to provide a support device which, once installed at the desired height, preserves the general aesthetic by integrating perfectly with the modular or removable element.

It is more particularly a support device associated with a profile having externally at least one T-shaped groove, in particular for supporting a shelf or spacer of modular or removable element whose frame is essentially formed of profiles arranged vertically , characterized by the fact that it includes a stirrup, a first part of which can be inserted into the T-slot,
has an external toothing intended to cooperate with the face
interior of at least one of the two lips delimiting said groove, and
a second part of which has the general shape of a hanging hook
projecting from the profile when said stirrup is inserted into said groove; and a cleat, hollowed out to let pass the part of the stirrup in the shape of
suspension hook, said cleat having the general shape of a square
the external angle of which defines a cam surface intended to cooperate
with the outer surface of the profile, so that after setting
place the cleat in an oblique position on the stirrup beforehand
inserted at the desired height in the T-slot, and tilting of said
cleat parallel to said T-groove to a final position of
abutment against said profile, said support device is automatic
ment locked on said profile and thus ready for use.

 Preferably, the first part of the stirrup has in section a general T-shape homologous to the T-groove of the profile, preferably with a double external toothing to cooperate with the two lips of said T-groove.

 Advantageously, the second part of the stirrup has a cutout widening below; in particular, the cutting of the stirrup has an additional curved clearance.

 As a variant, the stirrup consists of two symmetrical parts to facilitate its insertion into the T-shaped groove of the profile: in fact, each part can be inserted separately in a transverse direction, without there being any need to have access to the end of the profile.

 According to another advantageous characteristic, the cleat consists of two flanges joined together at least at the angle of the angle, where a heel is formed whose curved inner surface cooperates with the part of the hook-shaped stirrup, and the outer surface of which includes the cam surface cooperating with the profile.

 It is interesting that the cleat has two substantially orthogonal edges which are connected by an inclined facet at the angle of the angle.

 Advantageously, the cam surface of the cleat essentially consists of an eccentric edge connecting the inclined facet to the edge of said cleat abutting the profile in the final position.

 It is also interesting that the cleat has a latching means at its lower end, cooperating with the T-groove of the profile in the final position.

 According to another advantageous characteristic, the cleat has in the upper part a protruding tenon corresponding to a hole in the shelf or spacer to be supported, said tenon joining the two flanges constituting said cleat.

 It is then advantageous to provide that the projecting post has a double transverse lumen intended to receive the oblong head in section of an attached lever, so that the pivoting of said lever causes a lateral expansion of said projecting post, and thus a locking of the shelf or spacer on the cleat: this makes it very easy to maintain the shelf or spacer, even if it is installed in overhang.

 Preferably then, the added lever can pivot between the two flanges constituting the cleat, to a position inside said cleat in which the free end of said lever locks the latching means: the lever is operated to integrate it into the cleat then simultaneously locks the shelf or spacer on the cleat, and the locking of said cleat on the profile.

 It may also be advantageous to provide that the upper edge of the hook-shaped portion of the stirrup projects slightly, in the final position, from the upper edge of the cleat, so that the weight of the shelf or spacer is supported by said stirrup.

 Advantageously finally, the stirrup is made of metal, for example aluminum or steel depending on the material of which the profile is made, while the cleat is made of plastic, for example polyamide or ABS.

Other characteristics and advantages of the invention will appear more clearly in the light of the description which follows and of the appended drawings, relating to a particular embodiment, with reference to the figures in which: - Figure I is an exploded view in perspective illustrating a stretch of
hollow profile with four T-slots, and a conforming support device
to the invention, constituted by a stirrup and a cleat, with in addition here a
additional locking lever - Figures 2, 3 and 4 are elevation views in particular for
better distinguish its structure in two flanges with connecting heel, with
furthermore an expandable upper tenon and a lower engagement means
tage - Figures 5a to 5d are schematic views illustrating the establishment
of the previous support device and an associated tablet - Figure 6 is a partial perspective view illustrating the assembly as well
assembled and perfectly maintained.

 Figure I can distinguish a section of profile I with which is associated a support device according to the invention. Profile I is here a hollow profile having four T-shaped grooves 2, arranged longitudinally, and opening towards the outside by two lips 3. It goes without saying, however, that we could just as well provide profiles with a different structure, and externally comprising at least one T-shaped groove

 Such profiles are advantageously used for the assembly of furnishing elements in kit form, elements constituted by a frame formed by such profiles arranged vertically, and by shelves or spacers or the like arranged horizontally.

 As will be seen, the support device according to the invention makes it possible to easily and quickly organize the support of such shelves or spacers, at any desired height.

In accordance with an essential aspect of the invention, the support device essentially consists of a stirrup 4, a first part 5 of which, which can be inserted in a T-shaped groove 2 of the profile 1, has an external toothing 6 intended to cooperate with the face interior of at least one of the two lips 3 delimiting said groove, and a second part 7 of which has the general shape of a suspension hook projecting from the profile
I when said stirrup is inserted into said groove. In combination with the aforementioned stirrup 4, a stopper 8 is provided, hollowed out to let part 7 of the stirrup 4 in the form of a suspension hook, said stopper having the shape general of a bracket whose external angle defines a cam surface 9 intended to cooperate with the external surface of the profile 1, so that after the cleat 8 has been placed in an oblique position on the stirrup 4 previously inserted at the desired height in the T-groove 2, and tilting of said cleat parallel to said T-groove until a final position of abutment against said profile, the support device is automatically locked on said profile and thus ready for use .

 As can be seen in Figure I, the first part 5 of the stirrup 4 has in section a general T-shape homologous to the T-groove 2 of the profile 1, with in addition a double external toothing 6 of each side, to cooperate with the two lips 3 of said T-groove

Thus, when the stirrup 4 is inserted in the groove 2, the first part 5 of the stirrup slides freely in the said groove, the external teeth 6 being adjacent to the internal face of the two lips 3. The second part 7 of the stirrup 4 has for its part a cutout 10 widening below, so that a cooperation can occur between said stirrup and a part of the cleat 8 during the tilting of said cleat parallel to the T-groove. This will be better understood by referring to the description given below with reference to schematic figures 5a to 5d illustrating the successive phases of setting up the support device for the disadvantage. It may also prove to be advantageous that the cutout 10 of the stirrup ~ 4 has an additional curved clearance 11 facilitating the relative movement between the cleat 8 and the stirrup 4 when the support device is put in place.

 It may be advantageous for the stirrup 4 to consist of two symmetrical parts 4a, 4b to facilitate its insertion into the T-groove 2 of the profile 1, as illustrated in FIG. 1. In fact, each of the symmetrical parts 4a or 4b can easily be inserted laterally in a T-shaped groove 2, without it being necessary to slide the stirrup by the end of the profile (the dimensioning will preferably be chosen so that the width of each symmetrical piece 4a, 4b or slightly less than the space separating the free edges of the two lips 3 from the T-shaped groove 2). Such an embodiment is advantageous when it comes to setting up the support device on a furnishing element already partially assembled, since it is then unnecessary to have to dismantle the whole of said element.

 The stirrup 4 will preferably be made of metal, for example injected aluminum, steel, or zamak. In practice, a hard metal will be chosen if the support device is associated with a metal profile, such as an extruded aluminum profile, while a less hard and less expensive metal can be chosen in the case of a material profile. plastic, for example polyvinyl chloride.

 A cleat 8 will now be described in more detail, the particular structure of which will be better understood by also referring to the views in FIGS. 2, 3, 4.

 The cleat 8 here consists of two flanges 12, 13 joined together at least at the angle of the angle, where a heel 14 is formed, the curved inner surface 15 of which cooperates with the part 7 of the stirrup 4 in the form hook, and whose outer surface 16 includes the cam surface 9 cooperating with the profile 1.

 On the embodiment shown here, the two flanges 12 and 13 are joined by the heel 14 above, by a small additional spacer 17 provided in the middle part of the edge of the cleat 8 abutting against the profile 1, and finally by a tenon salient 18 on the structure and function from which it will be returned later.

 The cleat 8 has here two edges 19, 20 substantially orthogonal, connecting by an inclined facet 16 at the angle of the angle. The edge 19 corresponds to the edge contacting the profile once the support device is in place, the upper edge 20 being, in this final position, essentially horizontal.

 Various embodiments could be provided for producing the cam surface of the cleat 8, in such a way that there is an eccentric effect during the tilting of said cleat parallel to the T-groove for the positioning of the device. of support. The particularly simple embodiment illustrated here is such that the cam surface is essentially constituted by an eccentric edge 9, which connects the inclined face 16 to the edge 19 of said cleat abutting the profile I in the final position.

 It is also advantageous for the cleat 8 to have a latching means 21 at its lower end, for example produced in the form of two elastic hook strips, coming directly from molding with the remainder of the component part of said cleat. This latching means 21 can cooperate with the T-groove 2 of the profile I - in the final position, that is to say after tilting of the cleat 8 parallel to the T-groove until the edge 19 of said cleat stops against said profile.

The positioning of the support device which has just been described will be better understood with reference to FIGS. 5a and 5b: - Figure 5a: the stirrup 4 has been inserted in a T-shaped groove of the profile 1, at the
desired height; the cleat 8 is then brought into an oblique position
above the protruding part of the stirrup 4, the inclined facet 16 being
then substantially parallel to the outer face of the profile: the setting
place of the cleat 8 is thus easily done by displacement according to the arrow
22, until the heel 14 of said cleat reaches the cutout of the stirrup
4.

- Figure 5b: from the previous position recalled in dashed lines,
we tilt the cleat 8 parallel to the T-groove, as symbolized
by arrow 23, to a final stop position against profile 1,
position which is illustrated in solid line: the cooperation between the stirrup 4
and the cleat 8 during this tilting produces on the stirrup a movement
tending to apply the external teeth thereof against the faces
inside of the two lips of the T-groove concerned, so that the
support device is thus automatically locked on the profile to
the end of said tilting; it should be noted that the end of
tilting simultaneously engages the cleat 8 on the
profiled by means of the aforementioned latching means 21.

 The support device is then ready for use, and it is possible, after installation of a plurality of such devices, to have a shelf or spacer as appropriate.

 As can be seen in FIG. 5b, it may be advantageous to ensure that the upper edge of the part 7 of the hook-shaped stirrup 4 projects slightly, in the final position, from the upper edge 20 of the cleat 8, so that the weight of the shelf or spacer is supported by said stirrup, a piece having a rigidity greater than that presented by the cleat, which makes it possible to avoid any deformation of the cleat in the event of a heavy shelf and cleat produced in plastic material.

 It is also possible to provide a protruding lug 18 on the cleat 8, a lug which corresponds to a bore 24 in the shelf or spacer to be supported 100, such a lug being frequently provided to avoid any lateral sliding of the shelf or supported spacer.

 However, in the context of the present invention, the protruding lug 18 has a particular structure allowing it to further ensure a locking function of the shelf or spacer 100 on the cleat 8, as will be explained below.

 Indeed, if we refer again to FIGS. 1 to 4, it can be seen that the protruding post 18 is in fact hollowed out, and has, opening out towards the front, a light 25 having substantially the shape of a T, as well as a double transverse light 26 defining two side windows, these windows extending below by a small slot 27, the upper part of the protruding tenon being constituted by a flat disc 28 ensuring the junction at this level between the two flanges 12, 13 stopper 8.

Such a structure makes it possible to use an attached lever 29, shown in perspective in FIG. 1, said lever comprising a head 30 whose cross section is oblong, and a lower actuating end 31. The dimensioning of the head 30 of the lever reported 29 is such that the small dimension corresponds substantially to the width of the windows 26 of the protruding stud 18, and the large dimension corresponds to the lateral expansion which is obtained by pivoting said lever, expansion thus automatically producing a locking of the shelf or spacer on the cleat 8.

Indeed, if we now refer to FIGS. 5c and 5d, the final stages of the positioning process thus completed will be even better understood - FIG. 5c: after tilting of the cleat 8 until it stops against it
profile 1 and snap-fastening by means 21 (position in solid line
illustrated in FIG. 5b), the head 30 of the added lever 29 is then inserted
through the opening in T 25, until said head is positioned in
the windows 26 of the protruding tenon 18; the shelf or spacer 100 is
then positioned on the cleat by bringing the associated hole 24 on the
protruding post 18.

- Figure 5d: we proceed to pivot the attached lever 29 according to the
arrow 32, which has the effect of causing lateral expansion of the
protruding lug 18, and thus ensuring the locking of the shelf or
spacer 100 on the cleat 8, the free end 31 of said passing lever
then between the two flanges 12 and 13 of the cleat 8 to reach the
position shown in dotted lines.

It should be observed that in this final position of the added lever 29, a locking mechanism 21 is obtained simultaneously: in fact, when it is desired to unlock the cleat 8 to tilt said cleat upwards in order to disassembly of the support device, the lower part of the two flanges 12 and 13 is lightly pinched so as to release the latching means 21, but this is only possible when the free end 31 of the attached lever 29 is not not brought between said flanges. Thus, the pivoting of the added lever 29 simultaneously performs the locking of the shelf or spacer 100 on the cleat 8, and the locking of said cleat on the profile 1. At the same time,
The free end 31 of the attached lever 29 is completely erased inside the cleat 8, which in no way affects the aesthetics in the final position, as can be seen with regard to FIG. 6 .

 The added lever 29 will advantageously be made of injected aluminum or zamak.

 As regards the cleat 8, given its complex structure, it will be advantageous to produce it by plastic material by injection, this material being for example polyamide or ABS (Acrylonitrile-Butadiene-Styrene).

 The invention is not limited to the embodiment which has just been described, but on the contrary encompasses any variant incorporating, with equivalent means, the essential characteristics appearing in the claims.

 In particular, the support device of the invention can be used to support very diverse objects in various applications, such as hanging bars in a storage cupboard, shower tray handles, etc.

 Furthermore, the cleat of the support device may have very variable shapes depending on the application concerned: the cleat may for example be made in the form of a hook or hook for hanging various objects or accessories, or even be made in the form of a bar elongated to form drawer slides. The cleat can even in some cases be fully integrated into the object concerned.

 The foregoing observations will make it clear that the term "cleat" must be interpreted in a very broad sense, and in no way limited to the embodiment presently described.
