Description

La présente invention a pour objet une palette de manutention qui peut être réalisée en carton, en matière plastique, en bois moulé, ou tout autre matériau.The present invention relates to a palette handling which can be made of cardboard, plastic, molded wood, or any other material.

Les palettes de manutention en carton actuelles sont généralement constituées de longerons formant le plancher supportant la charge et de traverses reliant les longerons parallèlement entre eux, lesdits longerons reposant directement sur le sol ou toute autre surface. Une telle palette est connue par exemple du document US-A-4 867 074.Current cardboard handling pallets generally consist of side members forming the load bearing floor and sleepers connecting spars parallel to each other, said spars resting directly on the ground or any other surface. Such a palette is known for example from document US-A-4,867,074.

Un des problèmes posés par ce type de palettes en matériau non rigide tient à la résistance des éléments les constituant, et notamment à la faible résistance des longerons à l'écrasement. Pour y remédier on a proposé de réaliser des longerons à partir de feuilles de carton pliées plusieurs fois, de manière à obtenir des longerons d'une plus grande solidité.One of the problems with this type of pallet made of non-rigid material due to the resistance of the elements constituting them, and in particular the low resistance of longitudinal members during crushing. To remedy this, we proposed make beams from folded cardboard sheets several times, so as to obtain spars of a greater strength.

Toutefois les palettes ainsi réalisées présentent des risques de voilage du fait que les différents éléments qui les constituent ne sont pas complètement bloqués en position. En outre les opérations de pliage des feuilles en carton destinées à former les longerons, et la quantité de matériau qu'elles nécessitent, conduisent à des coûts de fabrication élevés.However, the pallets thus produced present risks of veiling because the different elements that constitute them are not completely locked in position. In addition, the folding operations of the cardboard sheets intended to form the longitudinal members, and the amount of material they require, lead to high manufacturing costs.

La présente invention a pour but de remédier à ces inconvénients en proposant une palette qui présente une bonne résistance à la charge et un coût de fabrication plus faible.The object of the present invention is to remedy these disadvantages by proposing a palette which presents a good load resistance and lower manufacturing cost low.

La palette selon l'invention se caractérise essentiellement en ce qu'elle comprend d'une part un plateau dont la face supérieure est destinée à recevoir la charge et dont la face inférieure et munie d'éléments de renforts longitudinaux ou transversaux pliés en U ou en V ; et d'autre part des éléments de support longitudinaux ou transversaux dudit plateau, également pliés en U ou en V, solidarisés longitudinalement ou transversalement aux éléments de renfort par emboítement réciproque d'encoches pratiquées dans lesdits éléments de renfort et de support.The pallet according to the invention is characterized essentially in that it includes on the one hand a tray whose upper face is intended to receive the load and including the underside and provided with reinforcing elements longitudinal or transverse folded in U or V; and on the other hand longitudinal support elements or transverse of said plate, also folded in a U or V shape, secured longitudinally or transversely to reinforcing elements by reciprocal interlocking of notches practiced in said reinforcing and supporting elements.

Si on se réfère à la figure 1 on peut voir que dans un premier mode de réalisation la palette selon l'invention comprend d'une part un plateau 1 destiné à supporter des charges, constitué de plusieurs feuilles de carton 10 d'une certaine épaisseur superposées et solidarisées entre elles par collage, et d'autre part des éléments de renfort 2 du plateau 1, réalisés à partir de feuilles de carton d'une certaine épaisseur pliées en V. Les éléments de renfort 2 sont solidarisés à la face inférieure 11 du plateau 1 grâce à des évidements longitudinaux 12, régulièrement espacés, dont une partie d'un seul évidement 12 est visible sur la figure. La solidarisation des éléments de renfort 2 est rendue possible par l'élasticité transversale de leurs côtés, dont les bords longitudinaux 21 sont calés dans le fond des épaulements 13 créés par les évidements 12.If we refer to Figure 1 we can see that in a first embodiment, the pallet according to the invention comprises on the one hand a plate 1 intended for bear loads, consisting of several sheets of cardboard 10 of a certain thickness superimposed and joined together by gluing, and on the other hand reinforcing elements 2 of the plate 1, produced from sheets of cardboard of a certain thickness folded in V. The reinforcement elements 2 are secured to the underside 11 of the plate 1 thanks to longitudinal recesses 12, regularly spaced, including part of a single recess 12 is visible in the figure. The joining of the elements reinforcement 2 is made possible by the elasticity transverse of their sides, whose longitudinal edges 21 are wedged into the bottom of the shoulders 13 created by the recesses 12.

On peut voir également sur la figure 1 les éléments de support 3 du plateau 1, disposés perpendiculairement aux éléments de renfort 2 et constitués de flancs de carton pliés en V et comportant chacun des encoches 30 pratiquées dans leurs bords longitudinaux 31, destinées à s'emboíter dans des encoches 20 pratiquées dans le pli longitudinal 22 des éléments de renfort 2 afin de les solidariser à ces derniers grâce à leur élasticité transversale. La palette ainsi constituée repose sur le sol ou toute autre surface par l'intermédiaire des plis longitudinaux 32 des éléments de support 3.We can also see in Figure 1 the support elements 3 of the tray 1, arranged perpendicular to the reinforcing elements 2 and formed cardboard sides folded into a V and each having notches 30 formed in their longitudinal edges 31, intended to fit into notches 20 practiced in the longitudinal fold 22 of the reinforcing elements 2 in order to join to the latter thanks to their elasticity cross. The pallet thus formed rests on the ground or any other surface through the folds longitudinal 32 of the support elements 3.

Les éléments de support 3 peuvent avantageusement avoir une section transversale en forme de U, plus particulièrement adaptée à supporter des charges lourdes.The support elements 3 can advantageously have a cross section in the form of U, more particularly adapted to support loads heavy.

Si on se réfère à la figure 2 on peut voir que les éléments de support 3 peuvent être constitués de l'assemblage de deux éléments 33 et 34 de section transversale en forme de U emboítés l'un 34 dans l'autre 33, destinés à être solidarisés à la face inférieure 11 du plateau 1 par leurs bords longitudinaux 31. L'élément de support externe 33 comporte deux découpes 36 pratiquées dans son fond 37, pour le passage de la fourche d'un engin élévateur. Les dimensions de l'élément interne 34 sont déterminées de manière que son fond 35 se trouve légèrement sous le bord supérieur des découpes 36, ce qui permet d'éviter d'abímer ce dernier lors du soulèvement de la palette.If we refer to Figure 2 we can see that the support elements 3 may consist of the assembly of two section elements 33 and 34 transverse U-shaped nested one in the other 33, intended to be secured to the underside 11 of the tray 1 by their longitudinal edges 31. The element of external support 33 comprises two cutouts 36 made in its bottom 37, for the passage of the fork of a machine elevator. The dimensions of the internal element 34 are determined so that its bottom 35 is slightly under the upper edge of the cutouts 36, which allows avoid damaging the latter when the palette.

Si on se réfère à la figure 3 on peut voir que dans un deuxième mode de réalisation la palette selon l'invention comprend des éléments de renfort 80 de section transversale en forme de V dont les bords longitudinaux 87 sont solidarisés à des planches de carton 81 réalisées à partir de l'assemblage de plusieurs feuilles de carton rectangulaires 82 superposées. Les éléments de renfort 80 sont reliés entre eux par des éléments de support 83 de section en V comportant dans leurs bords longitudinaux 88 des découpes 85 aptes à s'emboíter dans des découpes 84 pratiquées dans le pli longitudinal 86 des éléments de renfort 80. La face supérieure de la palette est dans ce cas formée par les faces supérieures des planches 81 juxtaposées, mais non jointives.If we refer to Figure 3 we can see that in a second embodiment, the palette according to the invention comprises reinforcing elements 80 of section transverse V-shaped whose longitudinal edges 87 are joined to cardboard boards 81 produced at from the assembly of several sheets of cardboard rectangular 82 superimposed. Reinforcement elements 80 are interconnected by support elements 83 of V-section with 88 longitudinal edges cutouts 85 capable of fitting into cutouts 84 made in the longitudinal fold 86 of the elements of reinforcement 80. The upper face of the pallet is in this case formed by the upper faces of the boards 81 juxtaposed, but not contiguous.

Si on se réfère à la figure 4 on peut voir que dans un troisième mode de réalisation la palette selon l'invention comprend un plateau 6 formé par des éléments de renfort 60 de section transversale en V solidarisés à des éléments de support 70 également de section en V.If we refer to Figure 4 we can see that in a third embodiment, the palette according to the invention comprises a plate 6 formed by elements of reinforcement 60 of V cross section secured to support elements 70 also of V section.

Les éléments de renfort 60 sont solidarisés aux éléments de support 70 par emboítement réciproque à l'aide d'encoches 71 pratiquées dans les éléments de support 70 et de lumières 69 pratiquées dans les éléments de renfort 60.The reinforcing elements 60 are secured to the support elements 70 by mutual interlocking using of notches 71 made in the support elements 70 and of lights 69 made in the reinforcing elements 60.

Les éléments de renfort 60 et les éléments de support 70 sont constitués de l'assemblage d'un premier flanc de carton 62,72 plié en V avec un deuxième flanc de carton 63,73 plié en U, recouvrant le premier sur une certaine hauteur.The reinforcing elements 60 and the elements of support 70 consist of the assembly of a first flank of cardboard 62,72 folded in V with a second flank of cardboard 63,73 folded in a U, covering the first on a certain height.

Les bases 74 des deuxièmes flancs 73 des éléments de support 70 reposent sur le sol et peuvent être recouvertes d'un revêtement ou d'un enduit isolant, tandis que les bases 64 des deuxièmes flancs 63 des éléments de renfort 60 forment le plateau de la palette.The bases 74 of the second flanks 73 of the support elements 70 rest on the ground and can be covered with an insulating coating or coating, while that the bases 64 of the second flanks 63 of the elements of reinforcement 60 form the pallet tray.

En outre afin d'éviter des déformations au niveau des encoches 71 des éléments de support 70, celles-ci sont pratiquées de telle manière que les bords longitudinaux 66 des branches 65 du U des deuxièmes flancs 63 des éléments de renfort 60 reposent sur les plis longitudinaux 77 des éléments de support 70 et que les plis longitudinaux 67 des éléments de renfort 60 viennent en appui sur le fond des encoches 71 pratiquées dans les éléments de support 70.Furthermore, in order to avoid deformations at the level of the notches 71 of the support elements 70, these are made in such a way that the longitudinal edges 66 of the branches 65 of the U of the second flanks 63 of the elements reinforcement 60 rest on the longitudinal folds 77 of support elements 70 and that the longitudinal folds 67 of the reinforcement elements 60 come to bear on the bottom of the notches 71 made in the support elements 70.

De manière à renforcer la solidarisation des éléments de support 70 et des éléments de renfort 60 ces derniers peuvent comporter, comme on peut le voir sur la figure 6a, un troisième flanc 68 de section transversale en V disposé contre la face interne du premier flanc 62 et dans lequel sont pratiquées des lumières 69 situées à courte distance des extrémités des branches du U formé par le deuxième flanc 63, en regard des encoches 61 pratiquées dans le premier flanc 62. Ainsi les extrémités rentrantes 76 des encoches 71 des éléments de support 70, visibles sur la figure 5, viennent se loger dans les lumières 68 en bloquant de manière efficace l'assemblage des éléments de support 70 avec les éléments de renfort 60.In order to strengthen the solidarity of support elements 70 and reinforcement elements 60 these the latter may include, as can be seen on the FIG. 6a, a third side 68 of cross section in V disposed against the internal face of the first flank 62 and in which are practiced lights 69 located at short distance from the ends of the branches of the U formed by the second flank 63, opposite the notches 61 made in the first flank 62. Thus the re-entrant ends 76 of notches 71 of the support elements 70, visible on the Figure 5, are housed in the lights 68 by blocking efficiently assembling the support members 70 with reinforcing elements 60.

Dans la variante de réalisation représentée à la figure 6b les éléments de renfort 60 comportent un seul flanc 62 muni de lumières 69 dans lesquelles viennent s'engager les extrémités rentrantes 76 des encoches 71 des éléments de support 70.In the variant embodiment shown in Figure 6b the reinforcing elements 60 comprise a single flank 62 provided with lights 69 in which come engage the inside ends 76 of the notches 71 of the support elements 70.

Si on se réfère enfin à la figure 7 on peut voir sur cette figure un élément de support 70 muni à l'une de ses extrémités d'une pièce d'assemblage 78 de même forme mais de dimensions légèrement inférieures, faisant saillie hors de l'élément de support 70 pour permettre son assemblage avec un autre élément de support 70' d'une palette voisine. Ce dispositif permet l'assemblage rapide de deux palettes pour en constituer une de dimensions supérieures, dont le désassemblage est également facile et rapide.If we finally refer to figure 7 we can see in this figure a support element 70 provided at one of its ends of an assembly part 78 of the same shape but slightly smaller, protruding out of the support element 70 to allow its assembly with another support element 70 'of a neighboring palette. This device allows the rapid assembly of two pallets to make one of dimensions which is also easy to disassemble and fast.
