Definitions

• the present invention relates to the technical sector of load-bearing type devices, that is to say a device capable of withstanding the pressure forces exerted notably laterally, in particular vertically, or in other directions, as will be explained hereinafter, etc., for example the weight of a load posed or fixed on said support device (in the preferred case of a stress or load exerted vertically).
• Pallet type devices are known to be produced by assembling pieces of wood (mainly) fastened in particular by nails, glues, staples, screws, etc., and the like.
• These devices consist of a wooden tray under which rows of wooden support elements will be fixed. These support elements are spaced apart to allow their handling and allow the arms of machines such as lift trucks or pallet trucks to pass between the elements to allow the gripping and handling of the pallet / load device assembly. .
• Another disadvantage is that the wooden pallets are relatively heavy, the weight may be between 10 and 30 kg and a handling agent does not having no trolley can lift more than 200 kg pallet (empty) per day with possible adverse consequences on his health.
• these pallets are capable of receiving very high loads in vertical stress.
• necrton type is meant here well known products made from low quality cellulosic pulps on paper machines or the like.
• cardboard is also very well known.
• patent GB 1 433 722 which has a folding system, this making it possible to replace the glue by said folding system.
• This prior system certainly represents a laudable attempt, but it is very limited in the sense that it is necessary to use cartons of very thin type, preferably of compact type or simple groove or simple micro groove because, in the use of large grooves or large thicknesses, the folding system takes more and more space and the box becomes unusable because the folding system, the rigidity can not be folded against a wall because of their rigidity accentuated. The higher the height of the box, the more important the folding system becomes. The useful volume is encumbered by folding systems.
• the GB patent does not explore any track other than making boxes and does not indicate any load-lowering capability on the doubly reinforced edges.
• the object of the present invention is therefore to create an ecological device load support ensuring the best ratio strength / lightness and all at a lower cost.

• load support type element, we denote here any element intended to have to withstand a load placed " above " , that is to say exerting a constraint in the "vertical” direction on its face or upper surface and in particular we designate here pallet elements, etc.
• the stress may in some cases be exerted in the vertical direction but on the lower face, or on both the lower and upper faces, for example if the load is placed under the pad or the paddle, or if the pad or paddle is placed in the vertical direction between two loads for example to create a vertical gap between two or more loads.
• the stress can also be exerted on a side face of the stud, by means of either a 90 ° rotation of the stud, or a manufacturing arrangement that will be easily understood by the skilled person.

It is also observed that at the right angles formed by said walls, it has been formed by folding "locking folds"> (1 1). (see operating mode below).
• lateral contact section is meant in the present application, any vertical section created in the lateral extension of the vertical walls (2, 3, 4, 5), and may be of any form adapted to ensure sufficient contact to reach the qualities sought (strength, resistance, elasticity).
• At least two elements (7, 9), preferably four, of flap type (7, 8, 9, 10), will be created and may be adapted to be fixed by any known means to an upper tray element (12) (especially glues: wood glues, heat fuses ... staples, clips, strapping straps, welding (if the material allows it), adhesives etc).
• Said flaps (7, 8, 9, 10) serve as a contact surface between the plate and the pad.

The plot is immediately put in shape. Then, just lock it with the outer triangles (a, b). By folding the outer triangle (b) on the inner triangle (d), the locking is achieved. The final hold blocking will be done by folding the outer triangle (a) on the inner triangle (c). Between the inner triangle (d) and the outer triangle (a), there is a cut of material on the line of the common side. All the triangles, the sides and the bottom are solidary in the same plate. Finally, in each corner, all the triangles forming the final assembly (11) are joined by at least one face.
