Definitions

  • the present invention relates to a multiple-use pallet, comprising a load surface with two mutually perpendicular sides and at least two supporting legs for supporting the load surface, which supporting legs each have a supporting surface facing away from the load surface, the supporting legs being substantially parallel to each other and having an extent parallel to one of the two sides of the pallet.
  • the invention further concerns a system of multiple-use pallets.
  • the most well-known multiple-use pallets are the wooden pallets known as EUR-pallets. Such pallets are sold and re-used in a recycling system in which used pallets can be returned to a recycling station in exchange for a predetermined sum of money.
  • the full-size version of these pallets measure 1200 x 800 x 150 mm.
  • the system is based on far-reaching standardisation and on the idea that those involved, at all levels, agree with the structure of the recycling system.
  • the system also features half pallets, such that two half pallets can be arranged on a full pallet to facilitate stowing of the goods.
  • the half pallets thus measure 800 x 600 x 150 mm. Wooden pallets of this kind are heavy, especially when wet.
  • a pallet of this kind has a number of advantages, namely that it can be manufactured according to more specific and adapted shapes, the material usage can be reduced and the total weight is lower.
  • a lower weight means not only that handling is made easier for the user, but also that the weight of the empty pallets that are shipped back to the recycling station is reduced, whereby also the environmental impact is reduced since less energy is consumed during transport.
  • the object of the present invention is to at least partly further improve the system described above.
  • This object is achieved by the invention through a system of multiple-use pallets, which comprises at least two multiple-use pallets, each pallet comprising a load surface with two mutually perpendicular sides which each have a certain length.
  • the length of one side of the first pallet is a first integer multiple of the length of one side of the second pallet
  • the length of the other side of the first pallet is a second integer multiple of the length of the other side of the second pallet, wherein any one of said first or said second integer multiple is different from one (1), and the pallets can be stacked in one another.
  • the first and second pallets are provided with corresponding supporting legs and load surface, so that the second pallet can be stacked in the first pallet, which means that the system of multiple-use pallets is a compatible system in which pallets of different size and with different load surfaces can be stacked in one another.
  • This is also of interest from the point of view of the environment, since it enables a single shipment to include a larger number of pallets, whereby fewer transport vehicles are required and the need for storage space is significantly reduced.
  • the size of the different pallets is adapted in such a manner that the pallets are compatible in terms of size with each other, which further improves the stackability and stowability.
  • the compatible system of pallets can also be such that any one of the lengths is essentially an integer multiple of the corresponding length, as described above.
  • the length of one side of the first pallet can be between 80-120% of a first integer multiple of the length of one side of the second pallet, preferably between 95-105%, more preferably between 98- 102%.
  • the other sides of the pallets can be provided according to the ranges exemplified above.
  • each pallet comprises at least two supporting legs for supporting the load surface, which supporting legs each have a supporting surface facing away from the load surface, the supporting legs being substantially parallel to each other and having an extent parallel to one of the two sides of the pallet, wherein at least one of the supporting surfaces extends up to the load surface and forms parts thereof.
  • a system of stackable and compatible pallets with a substantially intact load surface is thus provided, which pallets also have stable supporting legs, so as to allow improved handling of the pallets in pallet racks, on roller conveyors and in computerized warehouses.
  • a multiple-use pallet comprising a load surface with two mutually perpendicular sides and at least two supporting legs for supporting the load surface which supporting legs each have a supporting surface facing away from the load surface, the supporting legs being substantially parallel to each other and having an extent parallel to one of the two sides of the pallet. At least one of the supporting surfaces extends up to the load surface and forms part thereof.
  • a pallet is provided which has stable supporting legs, which at the same time help to ensure that the load surface is not perforated by too many large cavities.
  • the supporting legs have a "meandering shape" and run from the supporting surface up to the load surface they are able to carry part of the load.
  • the cavities in the load surface can be arranged such that the effective load surface adapted to support the goods arranged on the load surface constitutes more than 70% of the total area of the pallet, including the cavities. In other words, the cavities constitute less than 30% of the area of the pallet.
  • the effective load surface can constitute more than 80%, preferably more than 90%, and most preferably more than 95%, of the total area of the load surface, including the cavities.
  • each supporting surface extends substantially along the whole of said side. This layout of the load surface ensures that the pallet is supported in a stable manner on a surface and that it is particularly well adapted for placing in pallet racks or on roller conveyors.
  • each supporting leg in a region between the supporting surface and the load surface, is formed with at least one opening, which extends parallel to said side.
  • the opening enables appropriate handling of the pallet by means of lifting devices, such as the forks of a forklift truck, which can be inserted under the load surface of the pallet for lifting and transport of one pallet or a plurality of pallets stacked in one another.
  • the load surface is at least partly provided with a friction-enhancing material. This prevents the goods arranged on the pallet from sliding off too easily and it prevents the pallet from sliding off of a pallet rack, a roller conveyor or the forks of a forklift truck. According to one embodiment, it is only the load surface that is provided with a friction- enhancing material.
  • each supporting leg is conically widening from the supporting surface towards the load surface. This enables the supporting legs to guide the forks of, for example, a forklift truck into the correct position under the pallet.
  • each supporting leg forms an inner cavity which is defined by the load surface formed by the supporting surface and the walls extending from the supporting surface to said load surface, the cavity being open vertically downwards.
  • each supporting surface extends along its periphery at least partly up towards said load surface, each supporting leg forming an outer cavity which is defined by the supporting surface and the walls extending from the periphery of the supporting surface towards the load surface.
  • the outer cavity is open vertically upwards through the load surface.
  • the pallet can receive a second pallet stacked thereon, wherein the supporting legs of the latter are able to sink at least partly into said outer cavity so that the pallets are stowed together, thereby taking up less space.
  • This is of interest, for example, from the point of view of the environment, since it enables a single shipment to include a larger number of pallets, whereby fewer transport vehicles are required and the need for storage space is significantly reduced.
  • said outer and inner cavities are divided into a plurality of outer cavities and inner cavities, respectively.
  • said outer cavity is adapted to receive the supporting legs of a second pallet.
  • said pallet has three supporting legs, said supporting legs being symmetrically positioned in the pallet.
  • the pallet is manufactured by injection moulding of a plastic material.
  • said pallet is symmetrical about an axis that is parallel to one of the two sides of the pallet.
  • the axis can be located at, or run through, the centre of the pallet.
  • the pallet can further be symmetrically disposed along a geometric symmetry plane which extends parallel to one of the two sides of the pallet, at the centre of the pallet, and at right angles to the load surface of the pallet.
  • each supporting surface of the associated supporting leg has two parallel sections, which extend along substantially the whole of said side.
  • the load surface has, adjacent the respective supporting leg, two parallel and longitudinal, or elongated, outer openings, or cavities, which extend in the direction of, or parallel to, the respective supporting leg along substantially the whole of the respective supporting leg.
  • the two parallel sections of the supporting surfaces are adapted to be received in the parallel and longitudinal outer openings, or cavities, in the load surface when stacking two pallets.
  • the pallet is provided with runners, which each have two parallel, elongated supporting surfaces, which extend substantially along the whole runner, the load surface of the pallet being formed with corresponding parallel, elongated outer openings, or cavities, which are adapted to receive the elongated supporting surfaces when stacking one pallet on another pallet.
  • the pallet comprises intermediate longitudinal, or elongated, load surfaces disposed between the parallel, longitudinal outer openings.
  • the intermediate elongated load surfaces extend in the direction of and along substantially the whole of the respective supporting legs so as to increase the effective load surface of the pallet.
  • the outer cavity of the respective supporting leg of the pallet comprises projecting portions, or abutments, or stop means, disposed at a suitable height inside the cavity and adapted to form a support for a second pallet stacked in the pallet.
  • the stop means thus enable the formation of a distance between the load surface of a first lower pallet and the lower edge of the load surface of an upper, second pallet that has been stacked in the first pallet. More specifically, the supporting surfaces of the supporting legs of the upper pallet thus rest on stop means of the respective supporting legs of the lower pallet.
  • the distance can be adapted in a suitable manner, so that lifting devices, such as the forks of a forklift truck, can be inserted between two stacked pallets for lifting of the desired pallet or the desired number of pallets from a stack of pallets.
  • the distance is, for example, 37 mm, preferably between 10 mm and 100 mm, more preferably between 20 mm and 80 mm, and most preferably between 30 mm and 50 mm. Stop means can also be provided in the inner cavity of the respective supporting leg.
  • a system of multiple-use pallets comprising at least two multiple- use pallets.
  • Each pallet has two mutually perpendicular sides, which each have a certain length, the length of one side of the first pallet being a first integer multiple of the length of one side of the second pallet, and the length of the other side of the first pallet being a second integer multiple of the length of the other side of the second pallet. Any one of said first or second integer multiple is different from one (1).
  • the pallets can be stacked in one another. This is of interest, for example, from the point of view of the environment, since it enables a single shipment to include a larger number of pallets, whereby fewer transport vehicles are required and the need for storage space is significantly reduced. Moreover, this effect is even further enhanced by the fact that the size of the different pallets is adapted in such a manner that the pallets are compatible in terms of size with each other, which further improves the stackability and stowability.
  • the system of pallets can also include at least two pallets, which are arranged according to any one of the embodiments described above.
  • the system comprises at least two multiple-use pallets according to any one of the embodiments described above.
  • Each pallet has a certain size, and the size of one pallet is an integer multiple of the size of the other pallet, said integer multiple being different from one (1).
  • a multiple-use pallet comprising a load surface with two mutually perpendicular sides and at least two supporting legs for supporting the load surface, which supporting legs each have a supporting surface facing away from the load surface.
  • the supporting legs are substantially parallel to each other and have an extent parallel to one of the two sides of the pallet, wherein at least one of the supporting surfaces extends up to the load surface and forms part thereof.

  • a pallet for example a full pallet 1 , which is to receive two half pallets 1' may conveniently be provided with openings through the load surface 2 according to a structure that represents a "doubling" of the supporting surface sectioning of the half pallets 1 ", i.e. the supporting surface sectioning of a half pallet 1 1 is arranged adjacent the same supporting surface sectioning of the load surface 2 of the full pallet 1.
  • drainage openings are provided in the supporting legs 3, 3', 3" and 4, 4', and especially in their supporting surfaces 7, for draining of the supporting legs 3, 3', 3".
  • a substantially vertically oriented edge is formed along said side.
  • this edge together with the opening 8 itself and the upwardly oriented openings 10a, 10b, 10c through the load surface 2, can receive water. The water may then accumulate in the supporting legs 3, 3', 3" and 4, 4' between the vertical edges. This is undesirable, for example for sanitary reasons, and so a number of small, or a few large, drainage openings can be provided in the load surface 2.
  • edges are bevelled and that the edges of the openings 8 are rounded, since this helps to prevent lifting forks that accidentally hit an edge from being blocked or damaging the material of the pallet 1 , 1 ', 1". If the edges are bevelled and/or rounded they will guide the lifting forks into the correct position, thereby reducing the stress on the material and, thus, improving the service life of the pallet 1 , 1 ', 1".
  • reinforcement ribs of preferably two or more different heights immediately adjacent to the underside of the load surface 2 in the region of the supporting legs 3, 3', 3" and 4, 4', which reinforcement ribs, in addition to their reinforcing function, also ensure - and this is perhaps their most important function - that there is enough space so that air can circulate into the inner cavities defined between the load surface 2 formed by the supporting surface 7 and the walls formed where the supporting surface 7 extends upwards towards the load surface 2.

Abstract

La présente invention concerne une palette à usages multiples comprenant une surface de charge avec deux côtés mutuellement perpendiculaires et au moins deux pieds de support destinés à supporter la surface de charge, lesdits pieds de support présentant chacun une surface de support dirigée à l'opposé de la surface de charge. Les pieds de support sont sensiblement parallèles les uns aux autres et présentent une étendue parallèle à l'un des deux côtés de la palette. Au moins une des surfaces de support s'étend jusqu'à la surface de charge et fait partie de celle-ci. La présente invention concerne également un système de palettes à usages multiples. Le système comprend au moins deux palettes à usages multiples, chaque palette présentant deux côtés mutuellement perpendiculaires, chacun présentant une certaine longueur. La longueur d'un côté de la première palette est un premier nombre entier multiple de la longueur d'un côté de la seconde palette, et la longueur de l'autre côté de la première palette est un second nombre entier multiple de la longueur de l'autre côté de la seconde palette. L'un quelconque desdits premier et second nombres entiers multiples est différent de un (1). Les palettes sont empilables l'une dans l'autre.
