Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to the field of handling, and more particularly relates to a pallet rack display stackable simple to deploy and the same footprint in the deployed or undeployed position. BACKGROUND OF THE INVENTION In the field of handling and logistics, it is crucial to ensure the loading, transport, unloading or even presentation of goods in an optimal manner, that is to say in a secure and cost effective manner. In a manner known per se, the goods to be transported and distributed are stored on pallets, most often including sidewalls, such pallets being loading trays for the handling of goods, for example using forklifts and / or pallet trucks. The presence of palletsides provides a vertical support in addition to the horizontal support provided by the horizontal tray, thus allowing the loading and transport of high goods. Most of the time, the presence of these slats greatly complicates the storage of these pallets, mainly because of their vertical size: the stack of pallets with sideboards is impossible. Patent application DE921794 discloses a pallet for transporting goods made of wood, comprising foldable side panels. The storage of folded pallets of the same surface in the deployed position is thus greatly facilitated. However, this solution requires a support element to maintain the drop-side in the unfolded position and this support element is articulated along a position axis perpendicular to the axis of articulation of the side panels. This solution makes manufacturing more complex and therefore more expensive the solution and weakened the resistance of the pallets because of the presence of the holes for the different axes. This solution does not provide storage alternatives when the pallets are unfolded and possibly loaded with goods. It is also known in the international application WO 2010/041222 a folding pallet comprising folding side panels.

However, in the folded position the pallet occupies a larger surface area than in the unfolded position, which prejudices the storage of the pallets when they are not used. Finally to maintain the sideboards in erected position it is necessary to set up sleepers, which makes the deployment slower and requires the use of individual sleepers that must be stored separately and that can be lost. Although it is possible to stack at least two pallets whose sideboards are in the unfolded position, the arrangements for stacking pallets when the sideboards are in the unfolded position are different from those ensuring stacking pallets when the sideboards are in the unfolded position. the folded position. In addition these stacked pallets can not constitute displays because the sleepers now the sideboards prevent access to the goods by users. GENERAL DESCRIPTION OF THE INVENTION The present invention therefore aims to provide a means of transport and / or presentation of goods, to overcome one or more of the disadvantages of the prior art.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION With reference to FIGS. 1 to 7, the invention will now be described. In one embodiment and preferably, the display is made of a strong and lightweight material, for example and not limited to aluminum. In one embodiment, the display includes a base (1) for supporting at least a portion of the merchandise on the display. For example and without limitation, this base (1) has a square or preferably rectangular shape. Without limitation, this base is a platform made in one block. Preferably, the base (1) comprises a plurality of slats (10) arranged next to each other and held together in a frame serving to support said slats. A design of the base with a plurality of slats allows a saving of material and a reduced weight compared to a base made of a single block of material. In one embodiment, the display comprises a plurality of holding means (2) secured to the base (1), for example and non-restrictively reversibly, for example using screws and nuts. For example and without limitation, the display comprises four holding means (2) secured to the base at the corners of said base (1) rectangular. In one embodiment, each holding means comprises a horizontal wedge on which rests a corner of the base. In an alternative embodiment, the corners of the base (1) are welded or riveted to the holding means (2). In one embodiment, each holding means (2) comprises two parts located on either side of a horizontal plane (P) coinciding with the base. A holding means (2) comprises a first part (2A) forming a foot, intended in particular to rest on the ground. For example and without limitation, the display comprises four feet ensuring its stability. In one embodiment, each foot comprises a pad (26) of flexible material with anti-slip properties, for example and not limited to silicone, so as to further enhance the stability of the display. The holding means (2) comprise a second portion (2B) comprising two vertical cheeks (20, 21) spaced arranged vis-à-vis. In one embodiment, these two cheeks are themselves connected over their entire height by a vertical plate (22), called back in the following description, this plate being perpendicular to the two cheeks (20, 21). The cheeks (20, 21) and the back (22) thus form a gusset, this gusset being a channel having substantially a U shape. In one embodiment, the channels of the holding means are intended to receive the articulable end. of a profile (31) forming the upright, whose cross section has dimensions slightly smaller than those of the channel. The cross section of a profile can be any shape, for example polygonal, hexagonal, triangular or tubular. For example and in a nonlimiting manner, the profile has a rectangular or square section. For example and without limitation, a user can introduce a profile (31) vertically in the channel. In one embodiment, so that the vertical position of the profile (31) is maintained, the second portion (2B) of the holding means comprises a shim (24) cooperating with the two vertical cheeks (20, 21) and transforming the channel in a tube, on a portion distant from the end of the cheeks farthest from the base. In one embodiment, the profile (31) comprises at least one vertical groove (311) machined over at least a portion of the length of the profile (31) to the end integral with the angle (30), the groove (311) extending into the horizontal base (302) of the angle. For example and without limitation, this groove has a circular, quadrilateral or T-shaped section. In one embodiment, a flange (20) of at least one holding means (2) comprises an inclined plane (201 ) linking the amount of a profile (31) with the longitudinal amount of the base (1).

In one embodiment, the base (22) of the U channel of the second portion (2B) of at least one holding means comprises an inclined plane (220) linking the amount of a profile (31) with the post longitudinal of the base (1). In an alternative embodiment, the base (22) of the U channel of the second portion (2B) of at least one holding means is L-shaped along the profile (31) and the longitudinal amount of the base (1). In a preferred embodiment, the display comprises two holding means disposed vis-à-vis along a longitudinal amount of the base (1) whose base (22) of the U-channel comprises an inclined plane ( 220) linking the amount of a profile (31) with the longitudinal amount of the base (1), the two other holding means being such that the base (22) of the U-shaped channel is L-shaped along the section (31) and the other longitudinal amount of the base (1). This configuration is performed so that the loading is facilitated at a longitudinal amount of the base, said goods then being able to abut against the inclined planes (220) of the holding means located at the opposite longitudinal amount of the base (1) .In one embodiment, the profile (31) comprises at least one stop (310) intended to cooperate with a notch (200) located at one end of the cheek (20, 21). This stop stops the stroke of the profile (31) inserted in the channel of the corresponding holding means, and maintains the position perpendicular to the base (1) of the profile (31). In one embodiment, the stacking pallet display comprises cooperation means (25) with the openings machined in the cheeks of the holding means (2). For example and in a nonlimiting manner, these cooperation means (25) are removable, that is to say that the complete disassembly of the profiles (31) of the holding means (2), according to the needs of the user, is possible. In one embodiment, these cooperation means (25) comprise at least one hole machined in the section and passing through it from one side, this hole cooperating with a screw (250), passing through the profile and the flanges (20, 21). ) of the corresponding holding means, and a clamping nut (251). The head of the screw is sufficiently wide not to pass through the opening (23) of the cheeks, the head of the screw and the nut (251) being located vis-à-vis the outer face of the cheeks ( 20, 21). This solution has the advantage, by adjusting the tightening of the screw and the nut, to block the profile (31) in the chosen position.

The openings or openings (23) formed in the cheeks (20, 21) of the holding means (2) are configured so that the profile (31) is integral with the holding means (2) in different positions, preferably in two positions: a vertical position perpendicular to the base (1) and a substantially horizontal position against the base (1). For example and in a nonlimiting manner, in order to allow the existence of at least these two positions and with reference to FIG. 1c, the openings (23) machined in the cheeks (20, 21) have an inverted L shape, each opening (23) comprising in fact a vertical portion and a horizontal portion, the horizontal portion being furthest from the base (1). The vertical part of the opening (23) allows a user to lift the articulable section (31), that is to say move it away from the base (1) by sliding in the channel of the holding means ( 2) corresponding. The cooperation means (25) of the profile (31) thus traverse the vertical portion of the opening (23) to the corner formed by the inverted L of the opening (23). Continuing its stroke along the horizontal portion of the opening (23), the cooperation means (25) progressively move away from the first vertical plate (22), or back, of the holding means: the profile shifts therefore progressively back (22), thus providing a mechanical game to fold the profile (31) on the base (1).

In one embodiment, the profiles (31) are connected in pairs along one side of the base (1) via at least one bracket (30), so as to form a hinged (3) hinged. In one embodiment, the collapsible stackable pallet display is characterized in that a grid bottom is secured to at least one of its side walls. For example and without limitation, this grid bottom is fixed using screws and nuts or clips, at the level of the profiles of the sidewall. The channel U of each holding means (2) has an open U-shaped vis-à-vis in the direction of the side of the sideboard (3) opposite. The ends of the angle (30) are made integral with the ends of two profiles (31) not intended to cooperate with the holding means (2). The angle (30) may be welded to the ends of the profiles (31), but preferably the angle is screwed to the profiles (31) so as to maintain a display having a completely removable structure and modular. For example and in a nonlimiting manner, the angle (30) has an L-shaped cross section. In an alternative embodiment, each profile (31) of at least one side wall (3) of the display rack is formed of a first part intended to slide inside a second hollow part, the end of the second hollow part, which is not intended to receive the first part of the profile (31), being integral with the holding means (2 ). In addition, each section comprises locking means for locking the first portion of the profile (31) in the second part of the profile to a desired height for example by a user. In this way, it is easy to adjust the height of the side panels (3) of a display, for example and without limitation to values between 50 and 150 centimeters, preferably between 80 and 120 centimeters.

In one embodiment, the side panels (3) are articulated between two positions. The first position is a folded position substantially parallel to the base (1) of the display, so that the second portion (2B) of the holding means (2) of a first display is able to cooperate with the feet (2A) means for maintaining a second display. It is thus possible to stack on each other a plurality of folded displays, the feet of the top display unit cooperating with the end of the channel of the holding means (2). In one embodiment, the pads (26) of silicone are made so that they integrate at least partially in the channel of the holding means: thus, at least the width of a pad (26) has a dimension smaller than the internal distance separating the two cheeks (20, 21) of the holding means (2).

The second position is a vertical unfolded position substantially perpendicular to the base (1), so that the angles (30) of a first display stand are able to cooperate with the feet (2A) of the holding means (2). another display rack stacked on the first. In one embodiment, the angles (30) whose cross section is substantially L-shaped thus comprise a horizontal portion called base (302) and a vertical portion (301). The feet (2A) of the holding means (2) of a first display stand on the base of the angles (30) of a second display whose side panels (3) are in the unfolded position. In one embodiment, each bracket (30) comprises at least one shim (303), for example and in a non-limiting manner of cubic shape, integral with the horizontal base (302) of the brackets (30). These wedges (303) secure the position of a display resting on the side panels (3) in the unfolded position of a second display. When the feet (2A) of a display unit each comprise a silicone pad (26), it is obviously the pads which are in contact with the base (302) of the angles of a second display rack whose sides (3) are in unfolded position. In one embodiment, these wedges (303) are section tube portions, for example square or rectangular. This configuration of the wedges (303) allows for example and without limitation to insert inside at least one shim (303) a rod or another tube, which is attached at least one information presentation device for example a document holder or a label holder. In one embodiment, it is possible to stack the displays on each other, that the side panels (3) of the displays are in the unfolded or folded position. In other words, it is quite possible that, among a plurality of displays stacked on top of each other, some of the displays have side panels (3) in the unfolded position, and another part of the displays have side panels ( 3) in the folded position.

In one embodiment, the various elements of the display stand have no protruding portion relative to the periphery of the plane (P) of the base (1). In one embodiment, at least one transverse bar (32) is secured to the profiles (31) of a side wall (3), said bar being parallel to the bracket (30) of the side panel, the bar (32) being be positioned along the entire length of the profiles (31) between the base (1) and the angle (30). For example and without limitation, the ends of a transverse bar (32) are fixed to the profiles (31) by welding, preferably by screwing or with the help of clips so as to preserve the modular appearance of the display. A particularity of the invention is on the one hand its modularity as has been specified above in the description, and on the other hand the possibilities of customization, for example by changing the color of the display according to the needs of users, and / or for example by providing additional accessories easily integrating the invention.

Thus, the plate is disposed in a plane parallel to the base (1), between the side panels (3) of the display. This plate allows for example and without limitation to present goods on several floors in the same display. A further object of the invention is the use of two pallet stacking displays, having a tray between two displays placed side by side. To do this, the user hooks the plate insertion means to the transverse bars (32) of the side panels (3) vis-à-vis the two displays. In one embodiment, at least one information presentation device, for example a document holder or a label holder, is reversibly integrated with the display. It comprises on at least one of its sides insertion means, for example hooks, intended to collaborate with at least one crossbar (32) of a sideboard (3) in the unfolded position of a display.
