Abstract

Pallet characterised in that it is composed of a ribbed load-carrying tray 1 with several feet of generally prismatic shape, including four corner feet and two intermediate feet, and of a protrusion 10 around the perimeter having a peripheral support zone extended by a gutter 11 extending upwards by a vertical rim 13 forming a protruding border delimiting on the underface a folding-over and support area 14 for the lower edges of the immobilising cover. This invention is of interest to pallet manufacturers.

Description

La présente invention se rapporte à une palette en matière plastique thermoformée pour le transport, le stockage, la manutention et la présentation à la vente de produits de grande consommation. The present invention relates to a pallet made of thermoformed plastic for the transport, storage, handling and presentation for sale of consumer products.

Le domaine d'utilisation de l'invention s'étend non seulement au niveau des circuits et entrepôts classiques de circulation et de stockage des produits avant leur vente, mais aussi dans les rayons des magasins lors de la présentation à la vente. The field of use of the invention extends not only to the level of conventional circuits and warehouses for the circulation and storage of products before their sale, but also in store shelves during the presentation for sale.

Les palettes subissent les efforts importants lors des manipulations dont elles font l'objet au cours des diverses phases de circulation des produits dans les circuits de distribution depuis la fabrication jusqu'à la vente. Les contraintes mécaniques existent depuis le chargement et se poursuivent pendant le transport, le déchargement et- les multiples manutentions et manipulations, jusqu'à leur retour dans les circuits de production. The pallets are subjected to significant efforts during the manipulations of which they are the subject during the various phases of circulation of the products in the distribution circuits from manufacture to sale. Mechanical constraints exist from loading and continue during transport, unloading and multiple handling and handling, until their return to the production circuits.

Ainsi, les palettes doivent présenter simultanément une souplesse et une élasticité suffisantes pour encaisser les charges, chocs et déformations statiques et dynamiques en même temps qu'une résistance adaptée aux chocs latéraux et frontaux des engins de manutention ainsi qu'une résistance adaptée aux chocs dus aux chutes. Thus, the pallets must simultaneously have sufficient flexibility and elasticity to withstand the static and dynamic loads, shocks and deformations at the same time as a resistance adapted to the lateral and frontal shocks of the handling equipment as well as a resistance adapted to the shocks due to the falls.

Ces exigences sont d'autant plus difficiles à remplir que la matière dans laquelle sont réalisés les corps des palettes est souple et mécaniquement peu résistante comme le sont les matières plastiques en général. These requirements are all the more difficult to fulfill since the material from which the pallet bodies are made is flexible and mechanically not very resistant, as are plastics in general.

Les diverses tentatives de confection de palettes en matière plastique se sont soldées pour cette raison à des échecs plus ou moins prononcés. The various attempts to make plastic pallets have therefore resulted in more or less pronounced failures.

La palette selon la présente invention a pour but de réunir simultanément les caractéristiques techniques générales ci-dessus et de conférer à l'ensemble les avantages souhaités pour une palette tout en utili sant les moyens de production en grande série. The purpose of the pallet according to the present invention is to combine the above general technical characteristics simultaneously and to give the assembly the desired advantages for a pallet while using the mass production means.

On arrive ainsi à concilier des impératifs techniques apparemment contradictoires, faible poids, résistance mécanique et prix de revient unitaire peu élevé. We thus manage to reconcile apparently contradictory technical imperatives, low weight, mechanical strength and low unit cost price.

A cet effet, la palette en matière plastique selon l'invention se montre remarquable en ce qu'elle se compose d'un plateau porteur nervuré, de plusieurs plots, de forme générale prismatique, dont quatre plots de coin et deux plots intermédiaires, et d'une saillie périmétrique à zone périphérique d'appui prolongée par une gouttière s'étendant vers le haut par un rebord vertical formant une bordure en saillie délimitant en sous-face une plage de rabattement et d'appui pour les bords inférieurs de la housse d'immobilisation. To this end, the plastic pallet according to the invention is remarkable in that it consists of a ribbed support plate, several studs, of general prismatic shape, including four corner studs and two intermediate studs, and of a perimeter projection with peripheral support zone extended by a gutter extending upwards by a vertical rim forming a projecting border delimiting on the underside a range of folding and support for the lower edges of the cover immobilization.

La palette selon l'invention est réalisée en grande série par la technique du thermoformage dans toute matière appropriée se prêtant à ce procédé de fabrication. The pallet according to the invention is produced in large series by the technique of thermoforming in any suitable material suitable for this manufacturing process.

On peut indiquer, sans aucune intention de limitation, la matière préférée pour la réalisation de la palette selon l'invention. Il s'agit d'un polystyrène opaque, qualité choc, vierge ou régénéré. It is possible to indicate, without any intention of limitation, the preferred material for the production of the pallet according to the invention. It is an opaque polystyrene, impact quality, virgin or regenerated.

La palette selon l'invention présente un plateau porteur nervuré 1 et six plots creux dont quatre plots de coin 2, 3, 4 et 5 et deux plots intermédiaires 6 et 7 disposés sur les grands côtés en partie médiane de l'intervalle existant entre les plots de coin de manière à individualiser deux ponts de matière successifs 8 et 9 pour le passage des fourches de l'engin élévateur. The pallet according to the invention has a ribbed carrier plate 1 and six hollow studs including four corner studs 2, 3, 4 and 5 and two intermediate studs 6 and 7 arranged on the long sides in the middle part of the interval between the corner studs so as to individualize two successive material bridges 8 and 9 for the passage of the forks of the lifting machine.

La surface portante du plateau 1 est délimitée par une saillie périmétrique 10 en forme de gouttière 11 dont la gorge 12 est prolongée latéralement, immédiatement ou après une bande technique par un rebord vertical 13 matérialisant le périmètre extérieur de la palette selon l'invention. The bearing surface of the plate 1 is delimited by a perimeter projection 10 in the form of a gutter 11, the groove 12 of which is extended laterally, immediately or after a technical strip by a vertical rim 13 materializing the external perimeter of the pallet according to the invention.

La hauteur de ce rebord peut varier selon le type d'application. II est en principe suffisant pour constituer une bordure fermée d'appui ou de retenue destinée à maintenir sur le plateau les emballages qui pourraient glisser. The height of this rim can vary depending on the type of application. It is in principle sufficient to constitute a closed support or retaining border intended to hold on the tray the packaging which could slide.

Selon une autre application, la hauteur de ce rebord est réalisée plus importante car elle constitue un rebord de délimitation pour un produit de rigidification qui serait coulé dans les plots et sur le plateau porteur 1 comme on le verra ci-après. According to another application, the height of this rim is made greater because it constitutes a delimiting rim for a stiffening product which would be poured into the studs and onto the support plate 1 as will be seen below.

Cette bordure, de forme générale rectangulaire, possède des coins arrondis ou conformés en angle droit. This border, of generally rectangular shape, has rounded corners or shaped at right angles.

La saillie périmétrique 10 constitue en sous face une plage de rabattement et d'appui 14 pour les bords de la housse d'immobilisation et de protection en film thermorétractable. The perimeter projection 10 constitutes on the underside a fold-down and support range 14 for the edges of the immobilization and protection cover made of heat-shrinkable film.

Le plateau porteur 1 présente une zone centrale 15 inscrite dans le cadre formé par les plots de la palette. The carrier plate 1 has a central zone 15 inscribed in the frame formed by the studs of the pallet.

Cette zone centrale 15, de forme générale rectangulaire, comporte plusieurs grandes nervures longitudinales sous la forme de barres de grande largeur telles que 16 séparées par des gorges 17 profilées en V. This central zone 15, of generally rectangular shape, comprises several large longitudinal ribs in the form of very wide bars such as 16 separated by grooves 17 profiled in V.

La zone centrale 15 est bordée longitudinalement par deux plages longitudinales 18 et 19 identiques, interrompues en partie médiane par un plot intermédiaire 6 ou 7 , et à chacune de leur extrémité, par un plot de coin.  The central zone 15 is bordered longitudinally by two identical longitudinal areas 18 and 19, interrupted in the middle part by an intermediate stud 6 or 7, and at each of their ends, by a corner stud.

Ces plages longitud-inales sont conformées en une double nervure longitudinale 20 formée de deux nervures parallèles telles que 21 et 22 de même forme générale en barre que celles de la zone centrale -15 séparées également par une gorge 23 profilée en V. These longitudinal ranges are formed into a double longitudinal rib 20 formed by two parallel ribs such as 21 and 22 of the same general bar shape as those of the central zone -15 also separated by a groove 23 profiled in V.

Le plateau porteur 1 se termine latéralement par deux zones latérales d'appui 24 et 25 reliant les plots de coin correspondants entre eux. Chaque zone
latérale est 'formée d'une nervure centrale prismatique 26 et 27 comprise entre deux gorges parallèles 28, 29 et 30, 31 profilées en V à fond plat.
The carrier plate 1 ends laterally by two lateral support zones 24 and 25 connecting the corresponding corner pads together. Each zone
lateral is' formed of a central prismatic rib 26 and 27 between two parallel grooves 28, 29 and 30, 31 V-shaped flat bottom.

Le plateau porteur 1 est bordé au-delà de la
ligne du cadre déterminé par les plots de coin par une bordure périmétrique d'appui 32 prolongée latéralement par la saillie périmétrique 10.
The carrier plate 1 is bordered beyond the
line of the frame determined by the corner studs by a perimeter support edge 32 extended laterally by the perimeter projection 10.

Cette bordure périmétrique se compose de deux nervures transversales d'appui 33 et 34 et de deux nervures longitudinales d'appui 35 et 36 raccordées entre elles aux angles par des secteurs en- arrondi ou en angle droit 37, 38, 39 et 40 assurant la continuité du ceinturage et ainsi le soutien périphérique et la rigidité de bordure. This perimeter border consists of two transverse support ribs 33 and 34 and two longitudinal support ribs 35 and 36 connected to each other at the corners by rounded or right-angled sectors 37, 38, 39 and 40 ensuring the belt continuity and thus peripheral support and edge stiffness.

Les nervures ci-dessus renforcent, le plan porteur qui montre une rigidité intéressante permettant de supporter un poids réparti de 100 kg sans flèche notable. The above ribs reinforce, the supporting plane which shows an interesting rigidity allowing to support a distributed weight of 100 kg without notable arrow.

On examinera maintenant la conformation des plots servant d'éléments de contact avec le sol. We will now examine the conformation of the studs serving as elements of contact with the ground.

Les plots présentent une conformation générale prismatique permettant de favoriser l'imbrication des palettes lors de la superposition. La section des plots d'extrémité s'avère toutefois moins importante et de forme générale rectangulaire, de disposition telle que la longueur soit dirigée parallèlement à la direction générale transversale. The studs have a general prismatic conformation making it possible to favor the nesting of the pallets during the superposition. The section of the end studs, however, turns out to be smaller and of generally rectangular shape, of arrangement such that the length is directed parallel to the general transverse direction.

Les nervures et la bordure 32 constituent une zone d'appui telle que 41 à l'entrée de chaque plot.  The ribs and the edge 32 constitute a support zone such as 41 at the entrance of each stud.

La structure détaillée des plots apparaît clairement sur les vues en perspective et en coupe des premières figures. The detailed structure of the studs is clearly visible in the perspective and sectional views of the first figures.

Le corps des plots est constitué par la succession symétrique de deux saillies transversales telles que 42 et de deux saillies longitudinales telles que 43, de forme générale trapéSoldale, raccordées entre elles par des pans incurvés d'angle identiques tels que 44. The body of the studs is constituted by the symmetrical succession of two transverse projections such as 42 and two longitudinal projections such as 43, of generally trapezoidal shape, connected together by curved sections of identical angle such as 44.

Les saillies et pans ci-dessus convergent vers un plan 45 de contact de dimension suffisante pour assurer un bon appui avec le sol. The above projections and sides converge on a contact plane 45 of sufficient size to ensure good support with the ground.

Dans let cadre d'applications particulieres, on peut envisager de rehausser le rebord vertical 13 afin de constituer un périmètre d'étanchéité pour une matière solidifiable qui serait coulez dans les creux du corps de la palette, plots et gorges et jusqu'à ras bord dans le volume délimité par le plateau porteur 1 et le rebord vertical 13, en utilisant ainsi la palette thermoformée comme moule 46. In the context of particular applications, it is possible to consider raising the vertical rim 13 in order to constitute a sealing perimeter for a solidifiable material which would flow into the hollows of the body of the pallet, studs and grooves and to the brim in the volume delimited by the support plate 1 and the vertical rim 13, thus using the thermoformed pallet as a mold 46.

On peut ainsi confectionner une armature sous
la forme d'un corps rigide 4; incrusté dans les plots et sur la surface nervurée du plateau porteur 1.
We can thus make a frame under
the shape of a rigid body 4; embedded in the studs and on the ribbed surface of the support plate 1.

Pour assurer une épaisseur suffisante à la nappe rigide 48 constituant le plateau, on prévoit une bordure périmétrique rehaussée 49 de forme générale rectangulaire à coins 50 en angle droit ou légèrement arrondis, de la même façon que pour le plateau porteur précédent. To ensure sufficient thickness for the rigid ply 48 constituting the plate, an enhanced perimeter border 49 of generally rectangular shape is provided with corners 50 at right angles or slightly rounded, in the same way as for the preceding carrier plate.

Dans ce cas, pour améliorer le contact entre
la matière coulée et la matière plastique de la palette on pourra projeter sur la surface de la palette une colle liquide avant le coulage.
In this case, to improve the contact between
the cast material and the plastic material of the pallet can be sprayed onto the surface of the pallet with a liquid adhesive before pouring.

D'autres moyens de sol idarisation, de fixation et d'immobilisation peuvent être prévus tels que clous, vis, vis, agrafes... pour améliorer la cohésion et la rigidité de l'ensemble.  Other means of idarization soil, fixing and immobilization can be provided such as nails, screws, screws, staples ... to improve the cohesion and rigidity of the assembly.

On peut également utiliser la bordure périmétrique rehaussée 49 comme rebord de calage en vue d'immobiliser une charge de forme géométrique ajustée par exemple une caisse ou un groupement de caisses ou tout autre conteneur. It is also possible to use the raised perimeter border 49 as a wedging rim in order to immobilize a load of adjusted geometric shape, for example a box or a group of boxes or any other container.

La présente invention a été décrite ci-dessus en détail, il est bien entendu qu'elle ne saurait se limiter aux seules particularités des moyens décrits, mais qu'au contraire, diverses variantes et variations directes s' avèrent possibles telles que substitution par des matériaux ou moyens équivalents, adjonction d'éléments inopérants et autres modifications sans apport inventif.  The present invention has been described above in detail, it is understood that it cannot be limited to the specific features of the means described, but that on the contrary, various variants and direct variations prove to be possible such as substitution by materials or equivalent means, addition of inoperative elements and other modifications without inventive contribution.
