  • the pivoting side walls are of significantly different width so that one of the side walls in the folded position fits into the other pivoting side wall, which makes it possible to limit the height of the pallet box in the folded position.
  • This minimized height is important, because the search for a minimum volume in the folded position is one of the challenges of foldable bodies in order to maximize space savings (particularly in trucks on the way back).
  • the free ends of the bases, opposite the large flat face of the pallet exceed the side walls when the side walls are positioned parallel or substantially parallel to the large flat face of the pallet.

In this position, the distal end 26 of the lug prevents the first movable side wall 8 from tilting inside the body. In other words, the first movable side wall 8 is attached to the second side wall 10 via a holding means 18 according to the invention.
  • a holding means 18 consists of the lug 20 and the passage 32 provided in the appendix 34.
  • the holding means 18 makes it possible to attach simply and quickly the first side wall 8 to a second side wall 10. Of course, by carrying out the reverse steps, we can easily detach the first side wall 8 from the second side wall 10.
  • the pallet box comprises another holding means 18, identical or similar to that described above, allowing in the same way to easily attach or detach another upper corner of the first side wall 8 to a third side wall 12 adjacent.
  • the fourth side wall 14 of the body is also attached to the second side wall 10 and the third side wall 12 via holding means 18 according to the invention.
  • the first side wall 8 and the fourth side wall 14 can quickly and easily be folded onto the bottom of the body.
  • the first side wall 8 as well as the fourth side wall 14 are hereinafter described as mobile, because they are both linked to the bottom 16 of the body, by means of a means flexible connection 24, visible on the figures 9 And 10 .
  • the flexible connection means 24 allows a certain freedom of movement to said side walls. More precisely, the flexible connection means 24 is configured to allow the tilting of said side walls on the bottom of the body as well as their movement in a direction perpendicular to the bottom of the body in order to allow the implementation of the holding means 18 according to the invention.
  • lower edge 42 of the first side wall 8 and the lower edge 42 of the fourth side wall 14 are connected by a flexible connecting means 24.
  • lower edge is meant the side of a side wall which is closest to the bottom of box 4.
  • the flexible connecting means is a plate of the same nature as the side walls and of similar or slightly less thickness as well as of similar or less weight.
  • the flexible connection means 24 is connected to the side walls by a folding line 44.
  • the folding line(s) are positioned above the bottom 16 of the box, in order to facilitate the tilting of the side walls on said bottom.
  • the flexible connecting means 24 is attached at the level of the center of the bottom 16 of the body, in order to allow greater bending of the plate at its ends, when the side walls are raised to insert the lugs 20 into the passages 32 provided in appendices 34, as described above.
  • the flexible connection means 24 is attached to the bottom of the body in order to facilitate the unfolding of the side walls.
  • the flexible connecting means is held by reversible holding means of the screw type or other, in order to facilitate the replacement of the movable side walls in the event of damage.
  • the flexible connecting means 24 makes it possible to exert traction on the first side wall 8 as well as on the fourth side wall 14, when the plate forming the connecting means is covered by merchandise.
  • the plate is flattened on the bottom of the box as illustrated by the Figure 10 , mechanically driving the attached side walls linked to the plate towards the bottom of the body.
  • This vertical translation movement then forces the sliding of the lugs present on the side walls, at the level of the second ends 40 of the passages 32 provided in the appendages 34.
  • the first side wall 8 as well as the fourth side wall 14 can then no longer move. remove appendages, as long as the bottom of the box is covered with merchandise.
  • the holding means according to the invention therefore offers greater safety in use of a foldable pallet box, by allowing sufficient engagement of the holding means to ensure adequate cohesion of the side walls in order to contain a bulk commodity per example.
  • the second side wall 10 and the third side wall 12 are both movable and capable of tilting towards the bottom of the body thanks to pivoting means 46.
  • a pivoting means 46 consists of two bases 48 which are secured to the pallet 6 as illustrated by the Figure 5 .
  • Each base 48 is positioned opposite or substantially opposite a movable side wall. More precisely, the bases 48 are arranged so as to face the appendages 34 extending the second side wall 10 as well as the third side wall 12.
  • Each base 48 is attached to an appendix 34, via a pivot connection to a degree of freedom.
  • the pivot connections are aligned so that the side wall which is held to said pivot connections pivots around a pivot axis 50 present in the body 4.
  • the pivot axis 50 visible on the Figure 5 , is also perpendicular or substantially perpendicular to the first side wall 8 when the latter is unfolded as illustrated by the figure 1 .
  • the pivot axis 50 of the pivot connection is located at a distance of between 3 cm and 22 cm, preferably between 5 cm and 15 cm, from the side wall which pivots around said pivot axis.
  • the pivoting means 46 is not aligned with the side wall that it moves.
  • the side wall called hereinafter pivoting side wall does not have a folding line to allow it to tilt inside the body.
  • a fold line is likely to be deform or break after a certain number of uses.
  • the pivoting side wall moved by a pivoting means distinct from said wall is therefore less likely to deform or tear compared to a foldable side wall.
  • the non-aligned pivoting means and thanks to the appendages they make it possible to create an empty space under the appendages in order to accommodate the pivoting side walls 10 and 12.
  • the appendages 34 extending the second side wall 10 and the third side wall 12 can be compared to the branches of a “u”. These branches allow the second side wall 10 and/or the third side wall 12 to bear on the bottom of the body when said walls are tilted, as illustrated by the figures 5 And 6 . These “u”-shaped branches, bearing on the bottom of the body, allow the side wall to have greater rigidity and also the side wall to be positioned at a distance from the bottom 16 of the body. The side wall is therefore less likely to deform under the weight of another wall and/or less likely to crush a wall located below.
  • the side walls are made from a polypropylene bubble structure plate, in order to allow a certain flexibility between the branches of the "u" to facilitate the insertion of an opposite transverse wall and already folded onto the bottom of the box 4.
  • the stack of transverse walls can thus be more compact, while preventing crushing or damage to said walls.
  • the free ends 52 of the bases exceed the side walls when the side walls are positioned parallel or substantially parallel to the large flat face of the pallet.
  • the free ends 52 of the bases extend by a few centimeters from the side wall covering the other side walls. This embodiment advantageously allows the bases to support, for example a cover of the box or another pallet box, when the side walls of the box are folded.
  • a pallet box can comprise one or more holding means, without including pivoting means described above, or vice versa.
