The invention is characterised in that the extruded elements (10, 20-23, 30-32) comprise at least an extension (5, 7, 8, 14) co-operating with a wall and/or at least a clamp (15) co-operating with a matching housing (16) provided in the walls (2) to form, either a slide (11) support-rail (10), or a fixed supporting element (60-62), or a lock-support element (31, 32, 20-23, 50).

Description

System for constituting supports or displays or packaging

The present invention relates to a system for constituting supports or displays. The invention relates more particularly to a system for constituting supports or displays formed by means of extruded profiles, adapted to be engaged in openings formed in walls or uprights made for example of cardboard.

Shelf support elements are known between two vertical uprights consisting of pins comprising a first part intended to be engaged in an orifice formed in the uprights and a second part forming the shelf support. These support elements are relatively expensive and are not easy to implement.

It is also known from document FR-2 718 335, a support element comprising a horizontal core provided in its lower part with a jumper intended to be fitted on the lower edge of a light formed in a vertical upright, the element comprising on at least one of its sides, a shelf support surface.

However, in cases where the supports have to support large masses, it may happen that the fixing of these support elements on the walls is not sufficiently solid. Furthermore, these support elements are not suitable for the formation of displays allowing for example the arrangement of drawers or allowing the removable locking of adjacent walls or uprights.

An object of the invention is to provide a system for constituting supports or displays or packaging formed from sheets of cardboard and extruded profiles, constituting supports of great solidity, simple to put in place, making it possible in particular to form drawer supports or for locking adjacent walls or uprights.

This object is achieved by the fact that in the system of constituting supports or displays or packaging from cut and / or folded cardboard sheets and from extruded profiled elements adapted to be engaged on walls or uprights of cardboard, the extruded elements comprise at least two parallel legs integral with a central portion to form a slot intended to come to bear on the edge of at least one wall or upright or on the edge of a light formed in the walls or uprights, the extruded elements comprising at least one extension cooperating with a wall and / or at least one claw cooperating with a complementary housing formed in the walls to form either a support-slide element for a drawer, or a support-holding element, ie a locking support element. According to another particularity, a first of the two parallel legs of the slide-support element is formed by a first vertical branch of an oblong piece of transverse section having the shape of an L upside down, the second branch of the L constituting an extension parallel to the central portion, or horizontal base, forming a slide for a drawer, the support-slide element comprising on its length at least a second leg each forming with the first branch of the L an engagement slot on the edge upper of a respective lumen, the support-slide element comprising at least a first extension perpendicular to the central portion and of direction opposite to the second leg, intended to come to bear on the upper edge of a respective lumen.

According to another particularity, a support support element comprises on at least one of the two legs at least one claw situated inside the slot, the support support element being intended to be mounted on the coincident edges of at least two walls kept contiguous between the legs and each provided with at least one lumen arranged to cooperate with the claw or claws, to allow the walls to be joined.

According to another particularity, a support support element is mounted on the upper and coincident edges of at least two walls and has a first extension perpendicular to the central portion and of direction opposite the two parallel legs to form a lateral support for a sheaf element on the two integral walls.

According to another particular feature, a support support element has an extension in the plane of the central portion, the support support element being mounted at an edge formed by two adjacent perpendicular walls of a packaging or box, so as to constitute a bearing surface for at least one box strapping tape, the support support elements protecting the corners of the box against deformation caused by the ribbons, the two parallel legs being engaged through a cutout on a first wall, the extension resting on the wall adjacent to that on which the two parallel legs are engaged.

According to another particular feature, a locking support element has an extension parallel to the central portion forming a horizontal base or support surface, the locking support element comprising two extensions perpendicular to the central portion and in a direction opposite to the two parallel legs for forming a second slot intended to receive at least one wall and / or a rim of a shelf disposed on the base, the locking support elements comprising at least one claw on at least one of the two parallel legs and / or on at least one of the two extensions constituting the second slot, the claws being disposed at a sufficient distance from the central portion or from the base to provide the necessary flexibility to the leg or to the extension carrying the claw to allow mounting of the locking support element, the claws being intended to cooperate with complementary fastening housings fo rmés in the walls or in the edges, to ensure a better fixing of the locking support elements.

According to another feature, a locking support element comprises at least one reinforcing link between the base and the leg adjacent to the base. According to another particularity, the reinforcing link forms an oblique plane which connects the free ends of the base and of the adjacent leg.

According to another feature, a claw is located on the end of the leg adjacent to the base, that is to say on the leg closest to the free end of the base forming a bearing surface for a shelf in particular.

In another feature, a claw is located on the end of the extension perpendicular to the central portion which is closest to the free end of the base. In another feature, the end of the extension perpendicular to the central portion, which is closest to the base is curved towards the free end of the base, in particular to facilitate the mounting of a shelf edge between the two extensions forming the second slot. According to another particularity, the two parallel legs are spaced so as to be able to be mounted on the substantially coincident lower edges of two openings of two respective walls held contiguous between the legs.

According to another particular feature, the two walls held together by at least one locking support element, belong to the same folded partition so as to constitute substantially a tube forming a column, the two extensions forming the second slot receiving the upper edges of the openings of the two adjoining walls, the column being intended to be housed by its upper end in a complementary housing of a horizontal support or display plate, each column comprising in its walls at least one locking support element whose base projects radially on the periphery of the column to form at least one bearing surface for the underside of the horizontal support plate. According to another particular feature, a locking support element is mounted on the lower edge of a light of a first wall of a housing to closing cover which can be folded over at least part of the first wall, the extensions forming the second slot being spaced so as to be able to receive on the one hand, and permanently, the upper edge of the lumen of the first wall and, removably, the folded end of the cover on the first wall, the cover being housed between the upper edge of the light and the extension located outside the housing, the extension located outside the housing being provided with less a claw cooperating with a complementary housing formed in the cover and being flexible so as to allow an operator to ensure manual locking / unlocking of the cover.

According to another particular feature, one of the two parallel legs and / or the extension located inside the housing are provided with at least one fixing claw in the wall of the housing.

In another feature, a first of the two extensions forming the second slot is located at one end of the central portion, in the plane containing one of the two parallel legs, the second extension being located at the end of the base.

According to another particular feature, the claw or claws each have substantially the shape of a prism with a triangular base, the prism face or faces being inclined relative to the plane of the walls or uprights of cardboard during the positioning of the extruded elements, for facilitate their introduction into their respective complementary housing by sliding the claws on the cardboard and slightly bending the extensions and / or the legs provided with claws. Other features and advantages of the present invention will appear more clearly on reading the description below made with reference to the accompanying drawings in which:

FIGS. 1A and 1B represent an exemplary embodiment of a support-slide element (10) of the support construction system according to the invention. The element (10) support-slide, for example for drawer (11), is consisting of an oblong piece of cross section in L upside down. A first leg of the L constitutes a horizontal base (5) forming a slide for a drawer (11), the second (6B) is vertical and oriented downwards. Two small flat vertical plates (100, 101) are integral with the edge formed by the angle of the L by means of two respective horizontal portions (13) located in the plane of the base (5). The vertical plates (100, 101), for example rectangular or of any other shape, each constitute a lower projection (6A) downwards, forming with the second (6B) leg of the L a slot (7) for engagement on the lower edge of a respective lumen (1) of a wall (2) or upright. Preferably, the height of the lower projection (6A) is less than the height of the second (6B) leg of the L. The upper part of each vertical plate (100, 101) forms an upper projection (7) intended to come in press on the upper edge of the respective light (1). The height of the upper projection (7) can, for example, be substantially equal to the height of the second (6B) vertical leg of the L. The element (10) slide support is for example made of extruded plastic. The element (10) support-slide is intended to be mounted in a wall (2) or upright, constituted for example of cardboard, and comprising a light (1) provided for each slot formed by the projections (6A) lower and the second (6B) leg of the L. The lights (1) are for example rectangular and have a length equal to the length of the respective vertical plate (100, 101) intended to engage in the light (1). The height of the light (1) is less than the height of the respective vertical plate (100, 101). Of course, the lights (1) are spaced on the walls (2) or uprights by a distance corresponding to the spacing of the vertical plates (100, 101) on the slide support element (10). To mount the slide support element (10) in a wall (2), the operator rocks the latter so as to introduce each upper projection (7) into a respective slot (1), each upper projection (7) being held in contact with the upper edge of the respective light (1). Then the operator switches the support-slide element (10) from so that the lower projection (6B) formed by each vertical plate (100, 101) also enters the respective lumen (1). Then, the operator lowers the slide support element (10) so that the lower edge of each lumen (1) engages in the respective slot (70) formed by the lower projections (6A) and the second (6B ) leg of the L which is vertical. In this way the lower edge of each light (1) is supported on the lower face of a respective horizontal portion (13). Each upper vertical projection (7) is supported on the upper edge of a respective lumen (1), on the face of the wall (2) or of the upright which is situated opposite the base (5) forming a slide for a drawer (11). The lumen (1) can for example be formed by a rectangular slot and by a pivoting flap (not shown) formed above the slot and facilitating the introduction and removal of the element (10) slide support. Thus, by placing opposite two elements (10) of the slide supports respectively on two walls (2) or parallel uprights, two parallel slides are produced, provided for a drawer (11) for storage or presentation. Of course, the embodiment of the support-slide element (10) is not limited to the example described above. Thus, of the slide-support element (10) can comprise over its length more than two vertical plates (100, 101) each forming a lower projection (6A) and an upper projection (6B), the number of lights (1) in the walls (2) or upright being adapted accordingly. Likewise, the slide-support element (10) can comprise, over all or part of its length, a single vertical plate (100, 101) forming a lower projection (6A) and an upper projection (6B), the shape of the lights ( 1) in the walls (2) or upright being adapted accordingly.

FIG. 2A represents a reinforced support element (30) of the system for constituting supports according to the invention. The support element (30) has a horizontal base (5) forming a support surface for, for example, a shelf (17). At a first of its ends, the base (5) has two parallel lower projections (6A, 6B) forming a slot for mounting of the support element (30) on the lower edge of a light (1) formed in a wall (2) or upright. This same first end of the base (5) has two parallel vertical upper projections (7, 8). The upper (7, 8) and lower (6A, 6B) projections are for example made up of flat vertical, rectangular or any other shape surfaces. A first (7) upper projection, located at the end of the base (5), is supported on the upper edge of the light (1). This first (7) upper projection is supported on the face of the wall (2) which is located on the side opposite the end of the base (5) forming the bearing surface for the shelf (17). The second (8) upper projection is provided for example to accommodate a flange (18) of the shelf (17), the flange (18) being disposed between the wall (2) and the second (8) upper projection. For example, when the shelf (17) is put in place, the second (8) projection penetrates into a complementary slot (27) provided on the outer edge of the shelf (17). The support element (30) has a reinforcement link (14) between the base (5) and the lower projection (6B) adjacent to the base (5), that is to say the lower projection (6B) located on the side from the end of the base (5) which forms a support surface for a shelf (17). The reinforcing link (14) is for example made up of a link of oblique material connecting the free ends of the base (5) and the adjacent lower projection (6B). The support element (30) thus has great solidity while retaining its simple structure which can be formed from extruded plastic. The support element (30) is mounted in a lumen (1) of a wall (2), substantially in the same manner described above for the slide support element (10). Thus, the first (7) upper projection is introduced into a lumen (1), substantially in contact with the upper edge of the lumen. Then, the support element (30) is tilted so that the lower projection (6A) located at the end of the base (5) also enters the lumen (1). The support element (30) is then lowered so that the lower edge of the lumen (1) penetrates to the bottom of the slot formed by the two lower projections (6A, 6B). The shelf (17) or plate can then be mounted on the support element (30), so that the second (8) protrudes enters a complementary slot (27) provided on the outer edge of the shelf (17). For this purpose, the second (8) upper projection can be slightly flexible to facilitate the positioning of the shelf (17). The second end of the base (5), that is to say the end of the base (5) which has no projections, serves as a bearing surface for the horizontal part of the shelf (17).

FIG. 2B shows an alternative embodiment of the support element of the support construction system according to the invention. The support element (31) of FIG. 2B differs from that of FIG. 2A only in that the lower projection (6B) adjacent to the end of the base (5) forming a bearing surface for the shelf (17) has a claw (15) for hooking in the wall (2) or upright. Elements identical to those described above are designated by the same reference numerals. The claw (15), located for example at the end of the lower projection (6B), is intended to cooperate with a complementary housing (16) formed in the wall (2) to ensure better fixing of the element (31 ) reinforced support. The positioning of the support element (31) is carried out in the same way as for the element in FIG. 2A, with the only difference that the claw (15) is anchored in the wall (2) or upright at the end of the descent of the element (31) on the lower edge of the light (1). For this purpose, the projection (6B) provided with the claw (15) can be slightly flexible to allow easy positioning of the support element (31).

FIG. 2C shows another alternative embodiment of the support element of the support construction system according to the invention. The support element (32) of FIG. 2C differs from that of FIG. 2B only in that the second (8) upper projection has a claw (15) for hooking in the edge (18) of the shelf ( 17) which arranged on the base (5) of the support element (32). Elements identical to those described above are designated by the same reference numerals. The claw (15), located for example at the end of the second (8) upper projection, is intended to cooperate with a housing (16) complementary formed in the rim (18) of the shelf (17). The positioning of the shelf (17) on the reinforced support element (31) is carried out in the same way as described above, with the only difference that the claw (15) of the upper projection (8) comes anchor in the rim (18) of the shelf (17) when the latter is disposed on the support element (32). To this end, the slot (27) of the outer edge of the shelf (17), provided for the second (8) upper projection, has shapes and dimensions allowing the passage of the claw (15). Similarly, the upper projection (8) comprising the claw (15) is slightly flexible to facilitate the positioning of the shelf (17). FIG. 3A represents an exemplary embodiment of a locking support element according to the invention. The locking support element (20) of FIG. 3A is identical to the reinforced support element (31) of FIG. 2B, with the only difference that it does not include a reinforcement link between the base (5) and the adjacent lower projection (6B). Thus, the locking support element (20) of FIG. 3A comprises a claw (15) for anchoring at the end of the lower projection (6B) adjacent to the base (5). Elements identical to those described above are designated by the same reference numerals. The locking support element (20) of FIG. 2A is arranged on the wall (2) or upright in the same way as described above and also provides support for a shelf (17).

FIG. 3B represents an alternative embodiment of the locking support element according to the invention. The locking support element (21) of Figure 3B differs from the locking support element (21) of Figure 3A only in that the end of the second (8) upper projection is bent towards the end of the base (5) forming the bearing surface for the shelf (17). Elements identical to those described above are designated by the same reference numerals. This curved shape of the second (8) upper projection facilitates in particular the mounting of the rim (18) of the shelf (17) between the wall (2) or upright and the second (8) upper projection. FIG. 3C represents an alternative embodiment of the locking support element according to the invention. The locking support element (22) of FIG. 3C differs from the locking support element (21) of FIG. 3A only in that the end of the second (8) upper projection has a claw (15) d 'hooking in the rim (18) of the shelf (17). Elements identical to those described above are designated by the same reference numerals. The claw (15), located for example at the end of the second (8) upper projection, is intended to cooperate with a complementary housing (16) formed in the rim (18) of the shelf (17) disposed on the support element (32).

Obviously, the reinforced support elements (30 to 32) and the locking support elements (20 to 22) are not limited to the embodiments described above with reference to FIGS. 2A to 2C, respectively 3A to 3C. Thus, the base (5) may include two support surfaces for shelves (17), the two support surfaces being constituted by the base (5) and located on either side of the vertical projections. That is to say that in this case, the same support can serve as support for two shelves (17), on both sides of the same wall (2) or upright. Likewise, the two upper projections (7, 8) and the two lower projections (6A, 6B) may each include one or more claws (15) for anchoring. Advantageously, the claws (15) can have substantially the shape of a prism with a triangular base, the face or faces of the prisms being inclined relative to the plane of the walls (2, 12) or uprights of cardboard when the extruded elements. In this way, the positioning of the extruded elements is easy, the claws (15) sliding on the cardboard or on the edge (18) of a shelf (17) causing a slight bending of the extensions (5, 7, 8, 14) and / or legs (6A, 6B) provided with claws (15) to facilitate the introduction of the claws (15) into their respective housing (16). These claws (15) can also be located at any height on the projections (6A, 6B, 7, 8). The anchoring claws (15) can be formed over all or part of the length of the projections (7, 8, 6A, 6B) vertical. The number and the arrangement of the complementary anchoring housings (26) formed in the uprights (2) or rims (18) of shelves are then adapted accordingly.

FIGS. 4A and 4B illustrate an example of use of a locking support element (50) to constitute a display column (80). The locking support element (50) of FIGS. 4A and 4B differs from the locking support element (22) of FIG. 3C in that the first (7) upper projection also includes an anchoring claw (15) at its end. In other words, the two upper projections (7, 8) each have an anchoring claw (15). Of course, all or only part of the upper (7, 8) and lower (6A, 6B) projections may have anchoring claws (15). The two lower projections (6A, 6B) are spaced so as to be able to be mounted on the coincident lower edges of two slots (1) of two walls (2, 12, FIG. 4B) respective held contiguous between the projections (6A, 6B) . Furthermore, the two upper projections (7, 8) are spaced so as to be able to be mounted on the coincident upper edges of the same two slots (1) of the two adjoining walls (2, 12). The locking support element (50) is arranged on the openings (1) of the two walls (2, 12) joined in substantially the same manner as described above in the case of a single wall or upright. The two walls (2, 12) held together by at least one locking support element (50) may belong to the same partition, or cardboard plate, folded back so as to substantially constitute a tube (80, FIG. 4A) forming a column . The column (80) can be intended to be placed by one of its ends, in a housing (19) complementary to a plate (24) horizontal support, or display. The horizontal support plate (24) can be supported by at least three columns (80). Each column (80) may have in its walls at least one locking support element (22, 50) whose base (5) projects radially on the periphery of the column (80), to form a bearing surface for the underside of the plate (24) horizontal. FIG. 5A shows another alternative embodiment of a locking support element according to the invention. The locking support element (23) of FIG. 5A differs from the locking support element (23) of FIG. 5A only in that the horizontal base (5) does not have a bearing surface intended for a shelf for example. That is to say that the two upper vertical projections (7, 8) are formed respectively on the two edges of the base (5). As before, the two parallel lower projections (6A, 6B) form a slot (70) for mounting the locking support element (23) on the lower edge of a light (1) formed in a wall (2) or amount. The two upper projections (7, 8) are spaced so as to be able to receive between them two adjoining walls (2, 12). The locking support element (50) is arranged in the opening (1) of a wall (2) in the same way as described above. FIG. 5B shows an example of use of the locking support element (23) of FIG. 5A, for producing a device for locking / unlocking the closure of a cover (42) of the housing (40). The housing (40) has a closing cover (42) which can be folded down on at least part of at least one (2) of its vertical walls. The locking support element (23) is mounted in the opening (1) of a (2) wall of the housing (40) on which the cover (42) is folded down. The two upper vertical projections (7, 8) receive within them, permanently, the part of the wall (2) forming the upper edge of the lumen (1). When closing the housing (40), the folding end of the cover (42) can be slid between the first (2) wall and the second (8) upper projection, i.e. the upper projection (8) located on the outside of the housing (40). This second (8) upper projection can be provided with at least one claw (15) for anchoring in a housing (16) complementary to the cover (42) to ensure locking of the closure of the cover of the housing (40). In addition, advantageously, the second (8) upper projection is slightly flexible so that it can be pulled out of the housing (40) so as to allow easy locking / unlocking of the cover (42). The second (8) upper projection has been shown in dotted lines (88) in a position for unlocking the closure of the cover (42). In this unlocking position (88), the second (8) upper projection is pivoted towards the outside of the housing (40) around its joint with the base (5). Advantageously, at least one of the lower projections (6A, 6B) is provided with claws (15) for anchoring in the wall (2) of the housing (40). Similarly, the first projection (7), located inside the housing (40) can also be provided with at least one claw (15) for anchoring in the wall (2) of the housing (40). Of course, several locking support elements (23) can be arranged on the same housing (40) to ensure the closure of the cover (42) of the latter.

FIG. 6A represents a support-holding element (60) according to the invention, intended to ensure the junction between two adjacent walls (2A, 2B) superimposed. The support-holding element (60) comprises two parallel legs (6A, 6B) integral with a central portion (13) to form a slot (70). At least one of the two legs (6A, 6B) is provided with at least one claw (15) located inside the slot (70). Thus, the holding support element (60) can be mounted on the coinciding edges, for example upper, of at least two walls (2A, 2B) placed one against the other and each provided with at least one light (1). The support-holding element (60) is threaded onto the walls (6A, 6B) until the coincident edges of the latter come into abutment against the central portion (13) in the bottom of the slot (70). The lights of the walls (2A, 2B) are superimposed at least in part to cooperate with the claw (s) (15) of the holding support element (60). In this way the holding support element (60) makes it possible to ensure the joining and the securing of at least two walls (2A, 2B) to form packaging or supports or displays of various shapes. FIG. 6B shows an alternative embodiment of the support-holding element. The support-holding element (61) of FIG. 6B differs from that of FIG. 6A only by the fact that it comprises an extension (7) in the plane of one (6B) of the two legs (6A, 6B) parallel. The extension (7) extends in the direction opposite to the leg (6B). In this way, when the support-holding element (61) is mounted on the upper edges of two walls (2A, 2B) to secure them vertically, the extension (7) forms a lateral holding surface for a sheaf element on the walls (6A, 6B) secured.

FIG. 7A shows another alternative embodiment of a support-holding element according to the invention. The support-holding element (60) comprises two parallel legs (6A, 6B) integral with a central portion (13) to form a slot (70) and an extension (5) in the plane of the central portion (13) . FIG. 7B represents an example of use of the support support element of FIG. 7A to ensure the strapping of a box or packaging. The support-holding element (62) is intended to be mounted at an edge (64) formed by two adjacent perpendicular walls of a package or box (63). To this end, the box (63) includes a lumen (not shown) parallel to the edge (64) and intended to receive one (6B) of the two legs (6A, 6B) of the support-holding element ( 62). In this way, the slot (70) formed by the two parallel legs (6A, 6B) is engaged on an edge of a first wall, the extension (5) resting on the wall adjacent to that on which the slot is engaged ( 71). Thus, by having support-holding elements (62) all around the packaging or the box (63), it is possible to constitute, on each edge, a bearing or mounting surface for at least one ribbon ( 64) for strapping the box (63). In this way, the holding support elements (62) protect the corners of the box (63) against deformation caused by the ribbons (64).

Other modifications within the reach of the skilled person are also part of the spirit of the invention.
