Description

PALETTE A TRAVERSES EMBOTTEES DANS LES PLOTS
La présente invention concerne une palette qui est un plateau de chargement destiné à la manutention de marchandises par chariots élévateurs à fourche.PALLET WITH CROSSES BOTTLED IN THE PLOTS
The present invention relates to a pallet which is a loading platform intended for the handling of goods by forklift trucks.

Traditionnellement une palette est réalisée à partir de bois de médiocre qualité ou de récupération. Elle comporte une ossature qui est constituée de plots reliés par des traverses. Traditionally a pallet is made from poor quality or reclaimed wood. It comprises a framework which is made up of studs connected by crosspieces.

Elle comporte aussi au moins un dessus qui est constitué de planches parallèles , espacées les unes des autres et fixées par clouage ou agrafage sur la face supérieure des traverses. Par exemple une palette légère classique , illustrée à la figure 1, comporte en ossature trois ensembles comprenant chacun trois plots régulièrement espacés sur lesquels sont fixées à plat des planches dont la largeur est identique à celle des plots. Les trois ensembles sont disposés parallèlement ; cinq planches régulièrement espacées, sont fixées transversalement sur les trois ensembles, de préférence trois planches prenant appui sur les faces supérieures des planches formant traverses aux emplacements des plots. Les intervalles entre les plots délimitent les logements dans lesquels viennent s'emmancher les deux fourches du chariot élévateur.It also comprises at least one top which consists of parallel boards, spaced from each other and fixed by nailing or stapling on the upper face of the crosspieces. For example, a conventional light pallet, illustrated in FIG. 1, has a framework of three assemblies each comprising three regularly spaced studs on which boards are fixed flat, the width of which is identical to that of the studs. The three sets are arranged in parallel; five regularly spaced planks are fixed transversely on the three sets, preferably three planks bearing on the upper faces of the planks forming crosspieces at the locations of the studs. The intervals between the studs delimit the housings in which the two forks of the forklift come to fit.

Afin de minimiser l'encombrement , le poids, et surtout le coût, les planches utilisées sont de faibles épaisseurs : par exemple ltépaisseur des traverses est de l'ordre de 1,5cm. In order to minimize the bulk, the weight, and above all the cost, the boards used are thin: for example the thickness of the cross members is of the order of 1.5 cm.

Ce type de palette présente différents inconvénients. Etant donné leur faible épaisseur , les traverses doivent avoir une largeur suffisante pour supporter la charge ; par construction cette largeur est la même que celle des plots , qui est elle-même suffisamment importante pour assurer la stabilité et la rigidité de la palette : c'est-à-dire de l'ordre de lOcm. En récupération, il n'est pas facile de trouver des planches faisant une largeur de lOcm sur une longueur qui est variable selon les dimensions de la palette, le plus souvent comprise entre 80 et 100cm. Le mode de fixation des différents éléments entre eux ne donne pas à la palette une rigidité à toute épreuve : les traverses sont fixées à plat sur les plots, les planches de dessus sont fixées à plat sur les traverses.De plus à l'usage les palettes se détériorent , y compris les plots ; un plot abîmé ne peut plus être réutilisé. This type of pallet has various drawbacks. Given their small thickness, the sleepers must have a sufficient width to support the load; by construction, this width is the same as that of the studs, which is itself sufficiently large to ensure the stability and rigidity of the pallet: that is to say of the order of 10 cm. In recovery, it is not easy to find boards with a width of 10 cm over a length which is variable according to the dimensions of the pallet, most often between 80 and 100 cm. The method of fixing the different elements together does not give the pallet a rigidity to any test: the sleepers are fixed flat on the studs, the top boards are fixed flat on the sleepers. pallets deteriorate, including the pads; a damaged stud can no longer be reused.

Le but que s'est fixé le demandeur est de pallier les inconvénients précités en proposant tout d'abord une palette qui pour une même charge potentielle , nécessite des planches formant traverses de plus faible largeur et présente une meilleure rigidité, puis dans un second temps une palette dont les plots d'une part s'abîment très difficilement et d'autre part peuvent, s'ils sont abimés, être réutilisés. The aim set by the applicant is to alleviate the aforementioned drawbacks by first proposing a pallet which, for the same potential load, requires boards forming cross-members of narrower width and has better rigidity, then in a second step a pallet whose pads on the one hand are very difficult to damage and on the other hand can, if damaged, be reused.

Le premier but est atteint conformément à la palette de l'invention qui comprend , de manière connue, une ossature constituée de plots reliés par des traverses en bois et au moins un dessus constitué de planches parallèles , espacées et fixées à plat sur la face supérieure des traverses. De manière caractéristique , les traverses et les plots ont leur face supérieure dans le même plan , les traverses étant fixées sur les plots par emboîtement dans des encoches pratiquées dans la face supérieure desdits plots. Ainsi selon l'invention les traverses sont bloquées dans les encoches des plots, à la manière de tenons bloqués dans des mortaises ; la fixation des planches de dessus sur les faces supérieures à la fois des plots et des traverses conforte ce blocage et la rigidité de l'ensemble. The first object is achieved in accordance with the palette of the invention which comprises, in a known manner, a frame made up of studs connected by wooden crosspieces and at least one top made up of parallel planks, spaced apart and fixed flat on the upper face. sleepers. Typically, the crosspieces and the studs have their upper face in the same plane, the crosspieces being fixed to the studs by interlocking in notches made in the upper face of said studs. Thus, according to the invention, the crosspieces are blocked in the notches of the studs, in the manner of tenons blocked in mortises; the fixing of the top boards on the upper faces of both the studs and the cross-members reinforces this blocking and the rigidity of the assembly.

De préférence la face supérieure de la traverse est constituée par le chant de la planche correspondante. Ainsi il est possible d'avoir une résistance au moins supérieure à celle d'une planche à plat de largeur plus importante. Dans le cas d'une palette dite légère pour charger de 500kg ou plus , la traverse a une épaisseur d'au moins 2cm. Preferably the upper face of the crosspiece is formed by the edge of the corresponding board. Thus it is possible to have a resistance at least greater than that of a flat board of greater width. In the case of a so-called light pallet for loading of 500kg or more, the crosspiece has a thickness of at least 2cm.

Le but complémentaire est atteint par la palette de l'invention précitée, dans laquelle les plots sont dans un matériau plastique clouable. Le matériau plastique présente plusieurs avantages par rapport au bois : il a une déformation élastique qui lui permet d'encaisser les chocs; l'encoche peut être réalisée directement lors de la mise en forme du plot. De préférence le plot est obtenu à partir de polyéthylène de récupération. En cas de détérioration d'une palette, on peut éventuellement recycler les plots non immédiatement réutilisables dans la fabrication de nouveaux plots. The complementary object is achieved by the palette of the aforementioned invention, in which the studs are made of a nailable plastic material. Plastic material has several advantages over wood: it has an elastic deformation which allows it to absorb shocks; the notch can be made directly during the shaping of the stud. Preferably the stud is obtained from recovered polyethylene. In the event of deterioration of a pallet, the studs which are not immediately reusable can possibly be recycled in the manufacture of new studs.

D'autres avantages et caractéristiques de l'invention apparaîtront plus clairement à la lecture de la description qui va être faite d'un exemple de palette à traverses emboîtées dans les plots en plastique , illustré par le dessin annexé dans lequel
La figure 1 est une vue en perspective d'une palette traditionnelle,
La figure 2 est une vue partielle en perspective d'une palette selon l'invention.Other advantages and characteristics of the invention will appear more clearly on reading the description which will be given of an example of a pallet with cross members fitted into the plastic studs, illustrated by the appended drawing in which
FIG. 1 is a perspective view of a traditional pallet,
Figure 2 is a partial perspective view of a pallet according to the invention.

La palette 1 montrée à la figure 1 est une palette traditionnelle dont le dessus 2 destiné à supporter les marchandises comprend cinq planches 3 disposées parallèlement et régulièrement espacées les unes des autres . Ces cinq planches 3 sont clouées ou agrafées à plat sur trois planches transversales, formant les traverses 4 de ltossature de la palette 1. Chaque traverse 4 est clouée ou agrafée à plat sur trois plots 5 qui sont des billes de bois de forme cubique et qui sont placés à chaque extrémité et dans la partie médiane de la traverse 4 correspondante. L'ossature de la palette peut être renforcée par des traverses 6 fixées sur les faces des plots opposées au dessus 2 de la palette 1 et aussi par d'autres planches latérales non représentées. Pallet 1 shown in Figure 1 is a traditional pallet whose top 2 for supporting the goods comprises five boards 3 arranged in parallel and regularly spaced from each other. These five boards 3 are nailed or stapled flat on three transverse boards, forming the crosspieces 4 of the frame of the pallet 1. Each crosspiece 4 is nailed or stapled flat on three studs 5 which are wooden balls of cubic shape and which are placed at each end and in the middle part of the corresponding cross member 4. The frame of the pallet can be reinforced by crosspieces 6 fixed on the faces of the studs opposite the top 2 of the pallet 1 and also by other side boards not shown.

Les dimensions de la palette sont généralement de lm x 120m ou de 0,8 m x 1,20m ; les dimensions de la zone 7 entre deux plots successifs 5 est suffisante pour permettre le passage d'une fourche du chariot élévateur et l'écartement entre les deux zones 7,7' est suffisant pour l'introduction simultanée des deux fourches lors de la manipulation de la palette. L'épaisseur des planches de dessus 3 et des traverses 4 est de l'ordre de 1,5cm. The dimensions of the pallet are generally 1m x 120m or 0.8m x 1.20m; the dimensions of the zone 7 between two successive studs 5 is sufficient to allow the passage of a fork of the forklift and the spacing between the two zones 7, 7 'is sufficient for the simultaneous introduction of the two forks during handling from the palette. The thickness of the top boards 3 and the crosspieces 4 is of the order of 1.5 cm.

Chaque plot 5 est un cube de lOcm de coté.Each pad 5 is a cube of 10 cm side.

On a représenté sur la figure 2 la structure de l'ossature telle qu'elle est modifiée dans le cadre de l'invention par rapport à celle qui vient d'être décrite. FIG. 2 shows the structure of the framework as modified in the context of the invention with respect to that which has just been described.

Chaque plot 8 comporte une encoche 9 servant de logement à la traverse 10, de sorte que la traverse 10 se fixe par emboîtement dans les trois encoches 9 de trois plots successifs 8. Each stud 8 has a notch 9 serving as housing for the cross-member 10, so that the cross-member 10 is fixed by interlocking in the three notches 9 of three successive studs 8.

On comprend que la profondeur et la largeur de l'encoche 9 sont très légèrement supérieures à l'épaisseur e et à la largeur 1 de la traverse 10 de sorte que la traverse 10 pénètre dans l'encoche 9 mais que sa face supérieure 11 soit sensiblement dans le même plan que la face supérieure 14 du plot 8.It is understood that the depth and the width of the notch 9 are very slightly greater than the thickness e and the width 1 of the cross member 10 so that the cross member 10 enters the notch 9 but that its upper face 11 is substantially in the same plane as the upper face 14 of the stud 8.

Lorsqu'elle est en place dans les plots 8 et que la traverse 10 a une section rectangulaire , la traverse 10 est de chant, c'est-à-dire que le côté le plus petit de sa section est sur la face supérieure 11. L'épaisseur e est dans l'exemple décrit d'une palette dite légère, pour charges de 500kg au plus , de 2cm à 3cm. La largeur 1 du chant 11 est juste suffisante pour permettre le clouage ou l'agrafage de la planche de dessus sur la traverse 10. When it is in place in the studs 8 and the cross member 10 has a rectangular section, the cross member 10 is edge-shaped, that is to say that the smallest side of its section is on the upper face 11. The thickness e is in the example described of a so-called light pallet, for loads of 500 kg at most, from 2 cm to 3 cm. The width 1 of the edge 11 is just sufficient to allow the nailing or stapling of the top board to the crosspiece 10.

La planche de dessus 13 qui se trouve au droit d'un plot 8 a sa face inférieure qui prend appui sur le chant 11 de la traverse 10 et sur la face supérieure 14 du plot 8. Elle est clouée ou agrafée à la fois sur la traverse 10 et sur le plot 8. The top board 13 which is located in line with a stud 8 has its lower face which bears on the edge 11 of the cross-member 10 and on the upper face 14 of the stud 8. It is nailed or stapled at the same time on the cross 10 and on pad 8.

Les plots ont une forme extérieure cubique ou toute forme adéquate. Par exemple tout ou partie des plots d'une palette peut avoir la forme d'un parallélépipède à section trapézoîdale ; dans ce cas la surface d'appui au sol est plus importante que la surface d'appui des planches de dessus. The studs have a cubic external shape or any suitable shape. For example, all or part of the studs of a pallet may have the shape of a parallelepiped with a trapezoidal section; in this case the support surface on the ground is greater than the support surface of the top boards.

Les plots 8 peuvent être en bois, mais selon une version particulière de l'invention ils sont dans une matière plastique clouable , par exemple et de préférence,ils sont réalisés à partir de polyéthylène de récupération. Par broyage et compactage à chaud de déchets sélectionnés de polyéthylène, du type bouteille , sac poubelle, on peut obtenir directement un plot ayant la forme souhaitée dans lequel des clous peuvent etre introduits à force et y rester fichés solidement, y compris l'encoche. I1 n'est pas nécessaire d'usiner le plot pour réaliser l'encoche, comme cela est le cas des plots en bois. De plus les plots en matière plastique ont une certaine capacité de déformation ; les chocs peuvent être amortis sans détérioration de la palette. The studs 8 can be made of wood, but according to a particular version of the invention they are made of a nailable plastic, for example and preferably, they are made from recycled polyethylene. By grinding and hot compaction of selected polyethylene waste, of the bottle or trash bag type, it is possible to directly obtain a stud having the desired shape in which nails can be forced in and remain firmly inserted therein, including the notch. It is not necessary to machine the stud to make the notch, as is the case with wooden studs. In addition, the plastic pads have a certain deformation capacity; impacts can be absorbed without damaging the pallet.

L'invention n'est pas limitée au mode de réalisation qui a été décrit à titre d 'exemple non exhaustif mais en couvre toutes les variantes. En particulier il revient à l'homme du métier de déterminer , en fonction du type de palette et de sa charge potentielle, l'épaisseur e et la largeur 1 des traverses, la hauteur H du plot 8. On comprend que la hauteur H du plot peut éventuellement être plus importante que celle d'un plot traditionnel, dans la mesure où la présence de la traverse 10 obture partiellement la zone 15 dans laquelle doit pénétrer la fourche du chariot élévateur et qu'il importe que cette zone 15 ait une hauteur suffisante pour l'introduction de cette fourche. The invention is not limited to the embodiment which has been described by way of non-exhaustive example but covers all the variants. In particular, it is up to the person skilled in the art to determine, depending on the type of pallet and its potential load, the thickness e and the width 1 of the crosspieces, the height H of the stud 8. It is understood that the height H of the stud may possibly be greater than that of a traditional stud, insofar as the presence of the cross-member 10 partially closes the zone 15 into which the fork of the forklift must penetrate and it is important that this zone 15 has a height sufficient for the introduction of this fork.

Le plot 8 ayant une hauteur H de lOcm et la traverse une épaisseur de 2cm, la hauteur de la zone 14 est de 8cm. The stud 8 having a height H of 10 cm and crosses it a thickness of 2 cm, the height of the zone 14 is 8 cm.
