Stackable loading pallet consisting of two superimposed loading trays (11, 12) of generally rectangular shape, separated by spacers (13) which delimit longitudinal and transverse through openings (15, 16) in order to define at least two housings longitudinally and transversely spaced for receiving the forks of a handling machine, characterized in that the first plate (11) delimits the bottom of a cavity (20) with divergent edges (21) for the fitting of a rib (22) peripheral formed around the second plate (12).

Description

STACKABLE LOADING PALLET

  The present invention relates to the trays of

  loading of stackable pallets type.

  The loading platforms called pallets and designed essentially to allow the handling of loads by a forklift are universally used for example for the

  handling of unitary or combined products.

  The pallets are generally in the form of a grating made of wooden planks mounted on squared blocks constituting the support feet of the pallet and defining between them passages for the arms of the forks of handling equipment The drawbacks resulting from the use of wood as a material

  constitutive, both with regard to its fragility.

  its excessive weight and its hygrometric affinities resulting in accelerated decay and cleaning difficulties, have already led to the creation of plastic or metal pallets such

  as described in publication FR-A 2 513 214.

  These pallets have the drawback of constituting unitary structures with the related problems concerning the volume of stock Qe of empty pallets and, consequently, difficulties in handling the pallets which have been cleared.

of their charm.

  -2- The publication FR-A 2,531,406 describes a stackable container capable of being stacked in stacks in which slots and overlapping steps overlap when the containers are stacked but which prohibit self-positioning of the containers

one to another.

  The object of the present invention is to remedy these various drawbacks by proposing a stackable and juxtaposed pallet when empty with another pallet, making it possible to constitute pallets having the qualities of robustness and flexibility of use, superior to those of

  generally used unit pallets.

  The object of the invention is also to produce such a stable assembly of pallets capable of being handled by a forklift, without risk of damage to any of these pallets. Another object of the invention is to provide a dismountable pallet assembly of low unit cost with stacking possibilities allowing space savings of a set of empty pallets.

a stock of pallets.

  The invention also relates to a self-adjusting stackable loading pallet which promotes the

  constitution of particularly stable batteries.

  The invention relates more particularly to a pallet which comprises two superimposed load trays, generally rectangular in shape, separated

  -3 by spacers which delimit through longitudinal and transverse openings in the

  purpose of defining at least two lo Qements lonqitudina-

  spaced apart or transversely to receive forks from a handling bunker and allow

the engagement of said forks.

  According to the invention, the first plate delimits the bottom of a cavity with divergent edges for the embedding of a rib formed around the

second tray.

  According to another characteristic of the invention, transverse recesses in the shape of a rail allow the passage of the forks, these being provided on their lateral sides with projecting parts intended to facilitate the fitting and guiding of the forks while ensuring the stability of the palette. According to another characteristic of the present invention, the assembly of removable pallets comprises, in coulter, a second workpiece support element, substantially of the same dimension as the loading platform capable of being placed and loaded on said platform and being covered, at

  needs, by another built-in pallet.

  The stacking of such pallets makes it possible to produce a traditional structure with pallets provided, where appropriate, with intermediate supports provided with conditioned pieces, the number of which can vary according to the dimensions of the pallets, these -4- being able to be stacked with intermediate supports of variable dimensions and shapes, as required, to receive different parts

  on the total surface of the loading platform.

  Such a pallet being advantageously made of plastic, its constituent parts having dimensions, allow the use of plastic injection molds or a

rotational molding process.

  Other features and benefits of

  the invention will emerge from the following description

  of embodiments given by way of illustration, but in no way limiting, made in relation to the appended drawings in which: FIG. 1 represents, in perspective, an embodiment of the pallet according to the present invention, FIG. 2 represents, in perspective , another embodiment of the pallet, FIG. 3 is a representation with half-section view of a stacking of pallets, FIG. 4 is a representation with half-section view of another method of stacking pallets, Figure 5 is a perspective view of a pallet with its dividers for storing

  parts on a loading platform.

  -5- The example of a pallet 10 represented in FIG. 1 generally comprises two loading trays 11, 12 superimposed of generally rectangular shape separated by spacers 13 constituted by partitions connecting the opposite loading trays 11, 12 -These partitions ensure, if necessary, the guidance and positioning of forks not shown, of a forklift or

  a pallet translation device.

  To this end, the pallet has passages 15, 16 which open on the opposite lateral flanks thereof and mortises 17 which favor the

  passage of the forks of the translation device.

  The passages 15, 16 thus define

  Forks for handling equipment forks.

  According to the invention, the first plate limits the

  bottom of a cavity 20 with divergent edges 21.

  The second plate 12 is surrounded by a peripheral rib 22 whose configuration corresponds to the conditions of embedding in a cavity such that

from an adjacent palette.

  In order to facilitate the centering and stacking of the pallets as shown in Figures 3 and 4, the diverging edges 21 of the first plate 11 constitute a peripheral belt and are formed

with chamfers 23.

  -6- Furthermore, additional locking can be sought between the pallet 10 and an intermediate plate 24 intended to receive the members such

as 25 constituting the charge.

  To this end, the plate 11 carries a number of mortises 26, in which pins 27 can be engaged carried by the base of the plate

tab 24.

  According to another characteristic of the pallet, the belt formed by the edges 21 is directly limited by the sides 30 of the pallet at the level of the first plate 11 and by a lateral edge

  support 31 at the second plate 12.

  The empty pallets as shown in Figure 1 can, in this way, be stacked according to the configurations shown in Figures 3 or 4

depending on the desired storage.

  FIG. 5 also shows a molded configuration of intermediate plate 34, the surface of which is formed by cells for immobilizing the

organs 25.

  The intermediate plate 34 can, in turn, receive a cover 35 with cells necessary to protect the transported parts, which assembles

edge to edge with plate 34.

  This constructive measure allows tiered storage

  protected parts on a mime pallet 10.

  -7- According to one embodiment of the pallet, it can be obtained by direct molding with a plane of

  median joint or by rotcomoulaqe being, of course.

  that any other manufacturing process can be considered. 4933 'lf
