L'invention concerne le domaine des palettes de transport, et plus particulièrement les palettes à structure de base métallique, pouvant servir à de multiples applications selon leur "habillage" à l'aide de structures diverses, tels que sols et/ou parois, supports, rayonnages, structures de soutien, etc.The invention relates to the field of transport pallets, and more particularly pallets with a metal base structure, which can be used for multiple applications according to their "dressing" using various structures, such as floors and / or walls, supports , shelving, support structures, etc.

Dans divers domaines industriels, tel que notamment l'industrie automobile, le coût de fabrication des structures de base pour les palettes destinées au transport de pièces d'assemblage représentent un poids considérable dans l'économie générale des articles fabriqués.
Il s'ensuit une recherche continue quant à la simplification et la réduction des couts des structures de base pour palettes de transport.
In various industrial fields, such as in particular the automobile industry, the cost of manufacturing the basic structures for pallets intended for the transport of assembly parts represents a considerable weight in the general economy of manufactured articles.
It follows a continuous search for the simplification and the reduction of the costs of the basic structures for pallets of transport.

C'est notamment le cas pour les structures de base les plus couramment utilisées, notamment dans l'industrie automobile, comprenant une armature à profilés métalliques formant des longerons horizontaux longitudinaux, des longerons horizontaux transversaux et des poteaux d'angle verticaux, et impliquant un assemblage de renforcement / stabilisation au moyen de ski pour (au moins une partie) des longerons horizontaux.
La présente invention à pour objectif de réaliser une importante simplification et réduction des couts de fabrication des structures de base pour palettes de ce dernier type.
This is particularly the case for the most commonly used basic structures, especially in the automotive industry, comprising a metal profile reinforcement forming longitudinal longitudinal spars, transverse horizontal spars and vertical corner posts, and involving a reinforcement / stabilization assembly by means of ski for (at least a part) of the horizontal beams.
The present invention aims to achieve an important simplification and reduction in manufacturing costs of basic structures for pallets of the latter type.

L'invention procure ainsi une structure de base pour palettes comprenant une armature à profilés métalliques formant des longerons horizontaux longitudinaux, des longerons horizontaux transversaux et des poteaux d'angle verticaux, tandis qu'au moins une partie desdits longerons horizontaux implique un assemblage de renforcement / stabilisation au moyen de ski, dans laquelle structure de base le ski dudit assemblage de renforcement / stabilisation présente au moins une extrémité recourbée, de manière à être soudée à un profilé vertical formant poteau d'angle et à un profilé horizontal du longeron.The invention thus provides a basic structure for pallets comprising a metal profile frame forming longitudinal longitudinal beams, transverse horizontal beams and vertical corner posts, while at least a part of said horizontal side members involves a reinforcing assembly. / stabilization at ski means, in which base structure the ski of said reinforcement / stabilization assembly has at least one curved end, so as to be welded to a vertical profile forming a corner post and a horizontal profile of the spar.

Dans le présent contexte les expressions "longeron horizontal", "longeron horizontal longitudinal", "longeron horizontal transversal", "poteau vertical", "ski d'assemblage" (de renforcement / stabilisation) et "extrémité recourbée" sont à comprendre dans le sens suivant :

  • un plan "horizontal" d'une palette correspond à un plan parallèle au sol, la palette étant supposée disposée sur le sol en position d'utilisation;
  • la direction ou la face "longitudinale" d'une palette correspond à la direction ou la face de la palette perpendiculaire au sens d'introduction des dents d'un élévateur sous la palette (faces "avant" et "arrière");
  • la direction ou la face "transversale" d'une palette correspond à la direction ou la face de la palette parallèle au sens d'introduction des dents d'un élévateur sous la palette (faces "latérales");
  • la direction "verticale" par rapport à une palette correspond à la direction perpendiculaire au plan de base de la palette;
  • un "ski" d'assemblage de renforcement / de stabilisation d'une palette constitue une pièce métallique, essentiellement plane, constitutive d'un longeron d'appui au sol de la palette, et permettant d'assurer une certaine stabilité / solidité à l'assemblage de ce longeron et de l'ensemble de la palette, grâce à la connexion, par soudures (adéquatement disposées) aux autres éléments constitutifs du longeron et/ou de la palette.
  • Le "ski" est une expression bien connue en soi dans le jargon de la profession, également appelé "runner" en anglais.
  • Une "extrémité recourbée" d'une telle pièce métallique essentiellement plane implique que le bout de cette pièce (le ski) est pliée en au moins deux endroits de manière à présenter des points de contact / surfaces de contact (en vue de l'application de soudure) par rapport aux autres éléments constitutifs du longeron et/ou de la palette, en particulier par rapport à un profilé vertical formant poteau d'angle et à un profilé horizontal du longeron.
In the present context the terms "horizontal spar", "longitudinal longitudinal spar", "transverse horizontal spar", "vertical post", "assembly ski" (reinforcement / stabilization) and "curved end" are to be understood in the following meaning:
  • a "horizontal" plane of a pallet corresponds to a plane parallel to the ground, the pallet being assumed to be placed on the ground in the position of use;
  • the direction or the "longitudinal" face of a pallet corresponds to the direction or the face of the pallet perpendicular to the direction of insertion of the teeth of an elevator under the pallet ("front" and "rear"faces);
  • the direction or the "transverse" face of a pallet corresponds to the direction or the face of the pallet parallel to the direction of insertion of the teeth of an elevator under the pallet ("lateral"faces);
  • the "vertical" direction relative to a pallet corresponds to the direction perpendicular to the base plane of the pallet;
  • a "ski" of reinforcement / stabilization assembly of a pallet constitutes a metal part, essentially flat, constituting a support spar to the ground of the pallet, and to ensure a certain stability / durability assembly of this spar and the entire pallet, through the connection, by welds (adequately arranged) to the other components of the spar and / or the pallet.
  • "Skiing" is an expression well known in itself in the jargon of the profession, also called "runner" in English.
  • A "bent end" of such a substantially flat metal part implies that the end of this piece (the ski) is folded into at least two places so as to have points of contact / contact surfaces (for the purpose of applying welding) with respect to the other elements constituting the spar and / or the pallet, in particular with respect to a vertical profile forming a post. angle and to a horizontal profile of the spar.

L'utilisation d'un ski recourbé permet un assemblage hautement simplifié, moyennant une quantité réduite de soudures, particulièrement adapté à un montage automatisé.The use of a curved ski allows a highly simplified assembly, with a reduced amount of welds, particularly suitable for automated assembly.

Dans un mode de réalisation préférée de l'invention, la structure de base comprend plus particulièrement deux longerons horizontaux longitudinaux, deux longerons horizontaux transversaux et quatre poteaux d'angle verticaux.In a preferred embodiment of the invention, the base structure more particularly comprises two longitudinal longitudinal spars, two transverse horizontal spars and four vertical corner posts.

Selon une autre caractéristique préférée de l'invention, les longerons longitudinaux de la structure de base sont plus particulièrement de type ouvert à renforcement / stabilisation au moyen de ski à extrémités recourbées, soudées à un profilé vertical et à un profilé horizontal, tandis que les deux longerons transversaux sont fermés et formés de simples profilés à deux flanches.According to another preferred feature of the invention, the longitudinal longitudinal members of the base structure are more particularly open type reinforced / stabilized by means of curved ski ends, welded to a vertical profile and a horizontal profile, while the two transverse longitudinal members are closed and formed of simple sections with two flanges.

Selon un mode de réalisation particulièrement avantageux du nouveau concept selon l'invention, l'armature métallique pour la structure de base implique un seul type de profilés pour les longerons horizontaux longitudinaux et pour les poteaux d'angle verticaux, consistant plus particulièrement en un profilé de type 45-45-3 mm, de type 50-50-3 mm ou de type 60-60-3 mm.According to a particularly advantageous embodiment of the new concept according to the invention, the metal reinforcement for the basic structure involves a single type of profiles for horizontal spars. longitudinal and vertical poles, consisting more particularly of a 45-45-3 mm type profile, 50-50-3 mm type or 60-60-3 mm type.

Cette même figure montre également l'assemblage très simplifié des longerons latéraux, en l'occurrence le longeron en forme de profilé à deux flanches 4, soudé au poteau 6, avec une pièce de renforcement 11 soudée sur le flanche inférieur du profilé 4 et sur le poteau d'angle 6.
Cette réalisation très simple des soudures permet une réduction considérable des couts de fabrication des structures de base pour palettes selon l'invention.
The very simplified assembly of the longitudinal beams is shown in more detail in the figure 2 , showing the ski 8 with its angles of curvature 82 and 83 allowing the ski 8 to be welded to the profile 7 (at a point 81, not shown), and to the corner post 6 (at a point 84, not shown), and the reinforcing plate 9 welded, at its lower part, to the ski 8, in its upper part, to the profile 7, and optionally, on one side, on the corner post 6;
This same figure also shows the very simplified assembly of the side members, in this case the profile-shaped spar with two flanges 4, welded to the post 6, with a reinforcing piece 11 welded to the lower flange of the profile 4 and on the corner post 6.
This very simple embodiment of the welds makes it possible to considerably reduce the manufacturing costs of the basic structures for pallets according to the invention.

Les poteaux d'angle verticaux 6 sont formés de profilés de type carré de 50 x 50 mm et d'une épaisseur de 3 mm.
Les poteaux 6 d'angle sont munis de cuvettes d'empilement 12, simplement formées de bouts de profilés carrés 13 de dimensions tout juste supérieures à celles des profilés des poteaux d'angle 6, s'emboitant ainsi sur le profilé ces poteaux, et étant soudés sur l'extrémité de ces poteaux. Cette réalisation très simple des cuvettes d'empilement contribue à la simplification et la réduction des couts de fabrication des structures de base pour palettes selon l'invention.
The vertical corner posts 6 are formed of square type profiles of 50 x 50 mm and a thickness of 3 mm.
The corner posts 6 are provided with stacking cups 12, simply formed of square profile tips 13 of dimensions just greater than those of the profiles of the corner posts 6, thus fitting on the profile these posts, and being welded on the end of these posts. This very simple realization of the stacking bowls contributes to the simplification and reduction of manufacturing costs of basic structures for pallets according to the invention.

Des profilés 13, 14, de type carré de 50 x 50 mm et d'une épaisseur de 3 mm, constituent des traverses de soutien longitudinaux 14 et transversaux 15 pour le fond de la structure de base 1.
Des plots 16 (en forme de bouts de profilé) servent de support pour les traverses de soutien et de guides ("centreurs") pour le centrage de la structure de base sur les dents d'un élévateur. Cette réalisation très simple des supports de centrage (centreurs) contribue à la simplification et la réduction des couts de fabrication des structures de base pour palettes selon l'invention.
Sections 13, 14, of the square type of 50 × 50 mm and 3 mm thick, constitute longitudinal and transverse support beams 14 for the bottom of the base structure 1.
Plots 16 (in the form of profile ends) serve as a support for the support rails and guides ("centering") for centering the base structure on the teeth of an elevator. This very simple embodiment of the centering supports (centering) contributes to the simplification and reduction of manufacturing costs of the basic structures for pallets according to the invention.
