Abstract

A shelf 18 is supported by brackets 14,16 which are slidably mounted on wall rails 10,12. Each bracket has a resilient locking member 22(24) which co-operates with recesses 20 on the rails to provide vertical bracket adjustment to fixed positions. Each bracket includes a telescopic slider 42 whose outer edge abuts the edge of the shelf and which is adjusted by a ratchet-like device (55,56,60,61 Fig 5) whereby shelves of different depths can be accommodated.

Description

2352387 A SUPPORT DEVICE FOR WALL-MOUNTED SHELVES The present invention

relates to a device for supporting at least one wall-mounted shelf, the device comprising at least two brackets for carrying a shelf board, and including for each bracket at least one section member, the bracket having a rear face for co operating with the section member while being retained against displacement in a direction transverse to the length of the section member, the section member having at least one catch member while the bracket has at least one resilient locking member suitable for occupying a rest position in which it can co-operate with said catch member to prevent the bracket from moving relative to the section member and suitable for being moved resiliently away from said rest position into an unlocking position in which said locking member escapes from the catch member.

In certain known devices, the brackets can be constituted by independent parts which are fixed directly to the vertical support, e.g. a partition in a home, in order to carry a shelf board on the top face of the bracket. This means that each bracket needs to have at least two holes made for that bracket in the partition, with the bracket being fixed thereto by appropriate systems, e.g. screws received in dowels. Such fixing is quite complicated and the brackets are difficult to move.

Other known systems consist in fixing two strips to the wall, the strips being provided with regularly spaced-apart holes along their length, and the two brackets have hooks located in their rear faces.

The brackets can thus be hooked to the strips. The vertical positions of the brackets can be adjusted by causing their hooks to co-operate with such and such a hole in a strip. To install such a system, it suffices to fix the strips to a vertical support such as a partition by means of suitable fixing means, e.g. screws received in dowels.

2 Compared with the previously mentioned systems, systems making use of strips have the advantage of enabling a plurality of boards to be put into place one above another without any need to make separate holes for each bracket, and they also have the advantage of enabling the heights of the shelf boards to be adjusted.

Nevertheless, hooking brackets in holes in strips is an operation that could advantageously be simplified. In addition, in order to guarantee mechanical strength, such brackets and strips are generally made of metal.

Patent US 4 444 323 discloses a device using a section member of the type mentioned in the introduction. In that device, each bracket is hooked by means of studs received in housings presented in the section member associated therewith. Thus, to change the position of a bracket, the catch member needs to be unlocked, the bracket needs to be separated from the section member by disengaging its studs frcm. the housings in which they have been inserted, and then they need to be put back into some other region of the section member with the studs being engaged in new housings and the catch member needs to be locked again.

Those operations are fiddly and there is no way in which they can be performed while the brackets are carrying a board, even if the board is very light.

In addition, in those known systems, a given bracket is capable of supporting boards of a given width only. To enable the same device to carry boards of different widths, it is necessary to use brackets of a different length. If it is desired to replace a narrow board with a wide board, or vice versa, then it is necessary not only to change the board, but also to replace the brackets.

The invention seeks to provide devices for supporting a wall-mounted shelf that are further improved compared with the above-mentioned systems.

3 This object is achieved by the fact that in the device of the invention, the section member is a rail for fixing to a vertical support and on which the two brackets are suitable for sliding, the sliding of each bracket relative to the rail being prevented by the catch member, and by the fact that the top face of each bracket includes a slider suitable for being moved away from or towards the rear face of the bracket by sliding relative to a fixed portion thereof so as to fit the bracket to the width of a shelf board, the front end of the slider being suitable for forming an abutment for the edge of the board.

By means of these dispositions, each bracket slides relative to the rail with which it co-operates. it is therefore not totally separated from the rail when its height needs adjusting, thus making the bracket much simpler to put into place. When the bracket is caused to slide relative to the rail, the resilient locking member is constrained to occupy its unlocking position except when it is situated in register with a catch member belonging to the rail, and as soon as it comes into register with such a member, it can take up naturally its locking position without any particular manipulation being required.

The bracket slides on the rail while being retained against any displacement in a direction extending transversely to the length of the rail, which means in particular that it cannot tilt relative to the rail.

This connection, which is accompanied by the locking due to the co-operation between the locking member and the catch member, ensures that the bracket is properly held relative to the rail. The bracket and the rail can be made of various materials, e.g. plastics material. The rail is then advantageously extruded, while the bracket can be injected molded.

In order to remove the wall-mounted shelf temporarily, it suffices to release the locking members 4 of the brackets from the catch members of the rails and to slide the brackets until they can be separated from the rails. The rails can be left in place on the vertical support without looking ugly or inconvenient as would be the case for brackets fixed directly to said support.

The slider of each bracket makes it possible to adjust the brackets to accommodate different widths of shelf board. Thus, a user purchasing a single line of goods can install boards of different widths. The rear edges of the shelves come normally into abutment against the section members or the rear portions of the brackets, and their front edges come into abutment against the front ends of the sliders. 15 In a particular advantageously embodiment, each rail presents a plurality of catch members that are spaced apart from one another in the length direction thereof, thereby enabling the positions of the brackets to be adjusted. 20 Adjustment is performed very easily by guided sliding of the brackets on the rails once the locking members have been released resiliently from the catch members. Advantageously, for each bracket the resilient locking member is disposed in the vicinity of a bottom end of the rear face of the bracket, which end is opposite front the top face of said bracket which is for carrying the board.

The locking member is thus moved away from the face of the bracket which is to support the shelf. It is thus easily accessible and easy to handle. For example, when a shelf board is supported by two brackets, a user seeking to modify the vertical position of said board can manipulate both locking members simultaneously in both brackets so as to move the entire assembly constituted by the board and its two brackets without there being any need to remove the board, given that each locking member can be manipulated using one hand only.

In an advantageous disposition, for each rail and for each bracket, the catch member or the plurality of catch members comprise hollows or portions in relief formed on the rail, and the resilient locking member is formed by a resilient tongue carrying a locking zone suitable for co-operating with said hollows or said portions in relief so as to prevent the bracket from sliding relative to the rail when said tongue in its rest position.

This constitutes a simple embodiment of the catch members and of the resilient locking member.

Thus, advantageously, for each rail and for each bracket, the catch member or the plurality catch members are formed by the edges of recesses present in the front face of the rail that is to be remote from the vertical support, while the resilient tongue carries a stud suitable for penetrating into said recesses.

The rail can thus present a smooth surface, the catch members being set back from said surface. This makes it easy to slide the bracket relative to the rail without jerking. For example, the rail can be made by extruding a plastics material and the recesses can be formed by working on the extrusion.

The invention will be better understood and its advantages will appear better on reading the following detailed description of an embodiment given by way of non-limiting example. The description refers to the accompanying drawings, in which:

- Figure 1 is a perspective view from beneath of a support device of the invention carrying a shelf board; - Figure 2 is a section view on plane II-II of Figure 1; - Figure 3 is a fragmentary view from beneath of zone III of Figure 2; 6 - Figure 4 is an exploded perspective view showing the various elements of a rail and a bracket of the support device of the invention; and - Figure 5 is an enlarged view of region V in Figure 2.

Figure 1 shows two vertical rails 10 and 12 fixed to a support 1 such as a partition in a building. These rails are fixed to the support, for example by means of screws passing through holes 11. Each of the rails 10 and 12 co-operates with a respective bracket 14 or 16.

The brackets co-operate with the rails via their rear faces respectively referenced 14A and 16A, and their respective top faces 14B and 16B serve to carry a shelf board 18. The brackets can slide relative to the rails.

In the example shown, the rails can have a male dovetail profile whose head forms a respective front face 10A or 12A. The rear faces of the brackets then have respective female dovetail-shaped profiles to match.

This is an advantageous variant, but it would also be possible to provide rails with front faces having grooves forming a female dovetail profile while the rear faces of the brackets present respective male dovetail profiles.

It is possible to devise other profiles that are suitable both for enabling the brackets to slide relative to the rails and for retaining the brackets against displacement in a direction transverse to the length of the rails, in particular against displacement in the direction F tending to move the brackets away from the support on which the rails are fixed.

The forward direction is the direction represented by arrow F, and the rearward direction is the opposite direction going towards the partition 1.

To simplify, the description relates more particularly to the rail 10 and the bracket 14, it being understood that these are analogous to the rail 12 and to the bracket 16 respectively.

7 The rail 10 has a plurality of catch members 20 which are spaced apart from one another in the long direction L of the rail (the vertical direction). The bracket has a resilient locking member 22 capable of occupying a rest position as shown in Figure 1 in which it co-operates with a catch member 20 of the rail to prevent the bracket from sliding relative to the rail.

In the example shown, the catch members are formed by the edges of recesses formed in the front face 10A of the rail, while the locking member is formed by a resilient tongue 22 carrying a locking stud 24 suitable for penetrating into these recesses. In Figure 1, the locking member 22 is partially hidden and the stud 24 cannot be seen. It is engaged in a recess situated above a recess 20 that can be seen beneath the bracket and which is analogous thereto.

The resilience of the locking member pushes it naturally into its rest position in which the stud 24 penetrates into a recess 20.

Starting from this position, the locking member can be moved elastically so as to escape from the catch member of the rail, thereby allowing the bracket to slide along the rail.

In an example that is not shown, the tongue 22 can be moved in the direction F going away from the front face 10A of the rail in such a manner as to extract the stud 24 from a recess 20.

The rails 10 and 12 can be quite long and each can have a plurality of catch members, e.g. constituted by recesses 20, so as to enable the vertical position of each bracket to be adjusted.

It is also possible to use rails of smaller size and of length closer to the height H of the rear face of a bracket. Under such circumstances, only one catch member such as one of the recesses 20 need be present on the rail. The rail would thus constitute a support of small size that is relatively discreet. It can be fixed to a 8 partition by screws or the like which may possibly be hidden by the bracket when the bracket is in place.

Once the rails have been fixed by appropriate means to the vertical support such as a partition, the brackets are easily installed by causing the sliding tracks formed on the rail and on the rear face of each bracket to cooperate until the locking member of each bracket cooperates with a catch member of the corresponding rail.

This "short rail" variant is advantageous in particular when it is desired to have a removable wallmounted shelf. In order to remove a shelf, it then suffices to actuate the locking members to their unlocking positions and to slide the brackets so as to disengage them from the rails. The rails themselves can is remain fixed to the partition without impeding the user of the premises in any way. If the user again feels the need to install a shelf, it suffices to reengage the brackets on the rails.

Nevertheless, the preferred variant consists in using rails that are relatively long, in association with a plurality of catch members distributed along their length. It is thus possible to place a plurality of brackets on each rail and to adjust the positions of the various brackets as a function of the sizes of the objects that are to be placed on the shelves. The positions of the shelves can even be adjusted without removing them, since the brackets are very easy to manipulate, merely by actuating the locking members into their unlocking positions, and then sliding the brackets along the rails.

The fact of making the catch members in the form of recesses or hollows constitutes an advantageous variant. Putting a bracket into place on a rail is further simplified by the fact that, once the locking member has 3S been actuated into its unlocking position, it is possible to slide the bracket normally without any need to keep hold of the locking member until it again comes into 9 register with a catch recess and co-operates therewith to hold the bracket in place.

Nevertheless, it is also possible to devise a system in which the catch members are implemented by portions in relief formed on the rail, with a locking zone of the locking member co- operating with such portions in relief, such a zone being constituted, for example, by a retaining edge or the like.

In the example shown, it is advantageous for the resilient locking member 22 of the bracket 14 to be in the vicinity of the bottom end 14C of the rear face 14A of the bracket.

As mentioned above, the rails can be made by extruding a plastics material or a metal, for example.

Under such circumstances, the walls of the rails are generally relatively thin, and the above-mentioned recesses 20 can be made by drilling holes through the front face of the rail.

Arrangements can be made to ensure that the fixing zones of the rail on the vertical support, e.g. orifices formed through the rear face of the rail, are situated to correspond with such holes so as to enable members for fixing the rail to be manipulated from the front face thereof. For example, these fixing members can be constituted by screws that are Lnserted through the above-mentioned holes into dowels already placed in fixing orifices made in the partition, and that are tightened by using a tool that is likewise inserted via said holes.

The bracket 14 has a rear face 14A and a top face 14B disposed at right angles to each other. They are interconnected by connection cheeks 26 which impart the mechanical strength required to prevent the face 14B folding relative to the face 14A. The portion of the bracket which co-operates with the rail is closed relative to the front of the bracket by a cover 28 extending between the cheeks 26.

The cheeks 26 extend downwards so as to hide the sides of the locking member 22.

The bracket is advantageously formed by injecting a plastics material and the cover 28 can be hollow. As can be seen in Figure 2, a housing 30 is provided in the web to receive a locking member. This housing is in the form of a hollow extending from the bottom end 14C of the bracket, to which end it is open. It is closed towards the rear by a rear wall element 32 extending substantially in line with the rear face 14A of the bracket.

This wall element 32 has an opening, a notch, or the like 34 through which the stud 24 projects when the locking element 22 is in place in the housing. This locking element is formed by a resilient tongue which is actuated to press against the wall element 32 and which is held in place in the housing 30.

To do this, the tongue 22 is secured to a bearing tab 36 which extends on the side opposite the face of said tongue which bears against the wall element 32.

This bearing tab co-operates via its bottom end 36A with the edge 38A of a cutout 38 formed in the wall element 40 which defines the housing 30 on its front side opposite from the wall element 32. This edge 38A defines the bottom edge of the cutout 38.

The bottom end 36A of the tab 36 is shaped so as to exert a reaction force on the edge of the cutout 38 both in the vertical direction and in the horizontal direction. To this end, the bottom end 36A of the tab 36 has a bearing section that forms a right angle (vertical rear face and horizontal rim) which co-operates with the edge 38A of the cutout 38.

The tab 36 is connected to the tongue 22 in the vicinity of the top edge 22A thereof. The tab 36 acts as a spring which continuously actuates the tongue 22 against the wall element 32. When the tongue is moved in the direction of arrow F, the tab 36 remains in place in the opening 38 and thus holds the entire locking piece constituted by the tongue 22 and the tab 36 in the housing 30.

The tongue 22 can be shaped in such a manner as to be suitable for distributing the resilient stresses exerted thereon into particular zones of the piece in which it is made. For example, the front face of the tongue, opposite from the face of said tongue which co operates with the wall element 32, can have a local stiffening rib 22A. The resilience of the piece that includes the tongue is then obtained rather by the spring effect of the bearing tab 36.

The tongue 22 also has a handling extension 22B that is accessible from outside the housing 30. This extension is advantageously made in such a manner as to appear to be part of the body of the bracket when the tongue 22 is in its rest position. That is why, in the example shown, it extends forwards with a slight upwards curve in such a manner as to overlie a portion of the bottom wall of the web 28 adjacent to the housing 30.

The bottom ends of the cheeks 26 extend downwards beyond this bottom wall so as to receive the thickness of the extension 22B of the tongue 22. To make it easier to handle, the extension 22B has an opening 22'B suitable for receiving a finger.

The top face 14B of the bracket 14 has a slider 42 which can be moved away f rom or towards the rear face 14A of the bracket by sliding relative to a fixed portion of the bracket so as to match the size of the bracket to the width of the board constituting the shelf. The fixed portion is constituted by the body of the bracket which comprises the cheeks 26, the web 28, and a top fixed portion of the bracket defined laterally by the cheeks 26 and having a horizontal bottom 44. This fixed portion 46 is in the form of a channel section member that is upwardly open.

12 The slider 42 is generally in the form of an elongate element of vertical section adapted to enable it to slide in the hollow element 46 which defines the top face 14B of the fixed portion of the bracket.

The slider can be injection-molded out of plastics material and it can be hollow. Its top face can be closed, or on the contrary it can be defined merely by the top edges of its sides 42A and 42B which co-operate with the inside faces of portions of the cheeks 26 that open into the hollow element 46. Under such circumstances, the transversal section of the slider 42 is substantially U-shaped, like the hollow element 46.

The slider 42 can be guided in its sliding relative to the hollow element, for example by means of a set of complementary ribs and grooves or notches. In the example shown, the front end of the hollow element is defined by a U-shaped cross wall element 46A having two notches 46B formed therein to receive and guide ribs 50 that are formed on the sides 42A of the slider.

The slider is held against moving relative to the fixed portion of the bracket in any direction other than its sliding direction. The above-mentioned sets of notches and ribs contribute to holding it in this way.

In addition, provision can be made for a guide block to provide such holding. Thus, the slider 42 as shown presents in the vicinity of its rear end 42C that is to be found to the rear face 14A of the bracket when the slider is received in the fixed portion of the bracket, with a guide block 52 that is suitable for sliding relative to a slideway formed in the fixed portion of the bracket while being held in said slideway.

A window 54 is formed through the bottom wall 44 of the hollow element 46. The guide block is advantageously T-shaped, with the crossbar of the T-shape co-operating with the edges of the window 54 against the bottom face of the element 44 so as to prevent the slider from tilting relative to the fixed portion of the bracket.

The edges of the window form the slideway.

The window 54 has an enlarged portion 54A which enables the guide block to be put into place in said window. In the advantageous embodiment shown, this enlarged portion 54A is in the vicinity of the rear end of the window 54. After it has been manufactured, the slider 42 is inserted into the hollow element 46 in vertical displacement with the ribs 50 possibly being inserted into the notches 46B by snap-fastening, the top ends of the cheeks 26 which carry the wall 46A being capable of being moved apart elastically.

The bracket has means for holding the slider in position relative to the fixed portion of the bracket.

By way of example, these means can comprise indentations 56 formed in the bottom face of the slider and resting against the wall element 44.

The fixed portion of the bracket co-operates with a stop 58 suitable for occupying a rest position in which it co-operates with an indentation 56 so as to prevent the slider from moving relative to the bracket in at least one displacement direction, and suitable for being displaced elastically away from said position so as to escape temporarily from said indentations, thereby enabling the slider to move relative to the bracket.

In the example shown, the stop is formed by a tongue 58 that is held elastically in place in such a manner that its top face co-operates with the bottom face 42D of the slider. The top face of the tongue carries one or more indentations 60 disposed in such a manner as to co operate with the indentations 56 of the slider. The indentations 60 can be seen more clearly in Figure 5.

Advantageously, these indentations have a substantially vertical stop face disposed at a rear end, while they are inclined forwards in the direction of arrow F. Thus, when the indentations 60 co-operate with the indentations 56, it is no longer possible to pull the slider forwards.

14 In contrast, the indentations 60 and 56 slide over one another to allow the slider to be slid rearwards.

The tongue 58 is disposed at the front end of the hollow element 46. The bottom face of the wall element 44 carries hooks or the like 64 in which a portion 59 of the tongue 58 is engaged, which portion forms a holding tab that is horizontal in the example shown. The tongue 58 is thus naturally pressed against the bottom face of the wall element 44. The indentations 60 are carried by a portion 61 of the tongue which projects upwards and extends through a window 65 formed in the wall element 44. The edges of'the window co-operate with the sides of the upward projection 61 and enable the tongue to be prevented from moving horizontally. The top face of the upward projection 61 comes substantially level with the top face of the wall element 44. The resilience of the tongue 58 with its tab 59 naturally actuates the tongue 58 into contact with the bottom face of the slider.

The tongue 58 has a handling extension 66 which enables it to be moved elastically downwards so as to move the indentations 60 away from the indentations 56.

In the example shown, this extension 66 is partially masked by regions of the cheeks 26 which are adjacent to the front end of the bracket body. The extension 66 is in the form of a tab folded beneath the bottom face of the tongue 58. It can be handled via its free rear end.

The slider 42 is defined at its front end by a vertical wall element 68 which projects above the level top faces of the slider and of the fixed portion of the bracket (faces defined by the top edges of the cheeks 26 and of the sides 42A and 42B), thereby forming an abutment for the edge 18A of the board 18.

Advantageously, in the vicinity of its front end, the slider 42 has means enabling the slider to be secured to the board of the shelf. By way of example, these means comprise a hole 70 made through the slider and serving to receive a screw 71 which can be engaged in the board.

Each bracket is thus made of a total of four parts: the bracket body, the slider 42, the part which carries S the locking tongue 22, and the stop 58.

The minimum width of the board is determined by the distance between the rear face 14A of the bracket and the front edge (stop 58) of the slider 42, when the slider is pushed rearwards fully into its housing. To adjust the bracket as a function of the width of the board that it is to support, the slider 42 is pulled forwards beyond the front end of the fixed body of the bracket.
