Definitions

• the present invention relates to a removable modular pallet comprising at least one load plate supported by feet, said plate and said legs constituting independent modules.
• pallets made of wood, plastics, cardboard or the like are commonly used for storing goods and thus facilitating their handling by forklifts or other equivalent machines.
• the term "pallet” covers the transport pallets as such, generally standardized, but also any type of load carrier such as platforms, container floors, etc., of any size.
• the wood pallet is historically manufactured from separate elements and assembled by stapling or the like. These separate elements correspond to the economic constraints of cutting wood and the most fragile part of the wood pallet lies in his feet subject to shocks handling equipment.
• the recognized advantage of the wood pallet is its ability to be repaired in case of degradation.
• the plastic pallet is generally monobloc and manufactured in one piece by injection or molding, or by mirror welding. This type of manufacturing prohibits the use of recycled plastics because of their different withdrawal powers that would cause deformations in the pallet, and is therefore not part of a sustainable development approach.
• the manufacture of a monobloc plastic pallet is complex and expensive, which makes it non-competitive compared to the wood pallet especially. Molds or footprints are expensive and complicated because they require drawers and pins to unmold the pallet.
• the presses required for this type of manufacture are high pressure presses of the order of 2 to 3000 tons, bulky and having to rely on specially designed foundations, which represents a very heavy overall investment.
• the cycle time required for the manufacture of a monoblock pallet of this type extends beyond the minute, which further strikes its cost price.

If necessary, the interval between the plate and the soleplate can be adjusted by superimposing several spacers 50, 60. even, it is possible to superpose several spacers 50, 60 to change the height of the pallet when it is a simple pallet without sole.

• These housings 80 are non-through, in that the connecting piece 70 can not be introduced into these housings 80 from the outside of the device (from below or above), but only inside the device between two modules. Consequently, these housings do not constitute rupture zones and do not weaken the mechanical strength of the device.
• These housings 80 may be perforated for reasons of manufacture and cost of material.

Its curved periphery, like that of the spacers 50 of the following examples, has the advantage of self-positioning the pallet with respect to the handling machine when the forks are inserted into the fork passages P when they are not in use. not aligned.
• the assembly of the different modules requires for the same number of spacers 60, the double of connecting pieces 70, since each spacer 60 is assembled in the upper part to the load plate 30 and in the lower part to the support plate 43 .
