Definitions

  • the present invention relates to a pallet of the kind that comprises an upper carrier surface which is built preferably of a hollow structured sheet material folded to a box construction encasing a core of rigid foam, such as polystyrene or polyurethane e.g. polyurethane foam, and in the carrier surface lock bars are inserted to which the legs of the pallet are connected.
  • the invention relates in particular to a pallet which has a low net weight compared to conventional wooden pallets.
  • a pallet of this type is known from EP-A1-0 595 612, where the carrier surface of the pallet is built of a multiple of elements which consists of a hollow structured sheet material and a layer of rigid foam material being substantially encased in the hollow structured sheet, which at some places is welded, where said foam material can be ten times thicker than the hollow structured sheet material, and where the carrier surface of the pallet at its under side comprises a number of assembly holes in rows and in which the legs of the pallet are inserted and maintained with bracing means, preferably profile bars inserted into the carrier surface and where at least each leg is joined to one another by these bracing means which are welded to the hollow structured sheet material in order to combine the individual elements of the carrier surface to each other, as the legs at the respective rows at the lower ends are connected to a slide member which form the base of the pallet, which seen in a cross-sectional view consists of a head portion and a neck which is narrower than the head portion and in the lower portion of the legs is provided with slots which are open towards the bottom of
  • the purpose of the present invention is to provide a pallet which in its basic form is simple to assemble and which in a strengthened version is capable of absorbing higher loadings and impacts than the above described pallet.
  • the pallet is intended to be made in different variants which relate to the price of the pallet, its load carrying ability and other relevant parameters, which for example can pertain the suitability of the pallet for use in environments, where hygienic demands are present.
  • the support elements can furthermore be joined together by edges surrounding profiles, preferably of polymeric material and covering the main part of the circumference of the pallet an in the outer edges of said profiles one or more horizontal channels are made, in which one or more flat tapes can be received for surrounding and tying the pallet together.
  • Said pallet is furthermore characteristic in that the lock bars are hollow profiles which at the insertion end comprises an insertion wedge that simplifies the insertion o said bars.
  • the carrier surface of the pallet is held together by a light metal angl section profile provided along the entire circumference of the edge, and where the lock bars that hold the legs of the pallet and extend through the carrier surface are open at both ends.
  • one or more flat tapes are inserted through the opening of the lock bar and surround the pallet on two or more sections.
  • the side edges of the carrier surface are behind the hollow structured sheet material for absorbing impacts reinforced with sheets of hard plastic, such as polystyrene.
  • said pallet is in a further embodiment of the invention provided with a number of U-profiles according to the expected load transversing and inserted in the carrier surface, said U-profiles being fixed to the side reinforced polystyrene sheets on the long side of the pallet and having the opening horizontally orientated and in the vertical sheet section comprising apertures in which the longitudinal lock bars can be inserted, as the lock bars and the U-profiles together create a sort of reinforcement grit incorporated in the carrier surface of the pallet.
  • the legs are fixed to the carrier surface in a quite normal manner with the before mentioned lock bars that extend through the lock apertures in the upper section of the legs.
  • the pallet according to the invention comprises furthermore feet extending in the entire length of the pallet and fixed to the legs, said feet being characteristic in that they are built of a triangular profile, preferably of a polymeric material or light metal, and where the upwardly extending wedge has an oblique angle and where the other two angles are rounded, and to which feet the legs of the pallet are connected in a quite normal manner by intermeshing between the upwardly extending centre profile and the corresponding slots in the lower section of the legs, as the foot section comprises a slot on each side of the upwardly extending side and axially orientated openings that can be closed by corresponding closing and reinforcement profiles, said profiles comprising slots that by mounting on the upwardly extending part of the foot section surrounds the legs, and thereby fix the foot as the profiles are held in place by a folding of the foot section or by insertion of an end stop in the foot profile
  • the foot in another embodiment of the invention consists of a triangular profile with the same cross-section as the above mentioned foot, but unbroken in the circumference and where the leg is mounted in a the leg suitable aperture in the upward facing surface of the foot and in which aperture the leg is fixed with a lock bar that preferably extends in the upper section of the foot profile and through holes in the leg, whereby the two parts are fixed to one another.
  • the legs are designed in such a way that their strength can be increased by insertion of a vertical preferably squar reinforcement profile, preferably of light metal.
  • said carrier surface is according to the invention encased in another sheet layer, which sheet layer in the joints are sealed by gluing, weldin or joint filling material.
  • the pallet will as a consequence of the above mentioned embodiments furthermore be carried out as combinations of these, depending on to which purpose it is to be used and also how high loads it must be able to carry.
  • the pallet built with the greatest strength must be able to carry a loa of approximately 2000 kg on the carrier surface and the simplest and most inexpensively built approximately 600 kg.
  • the pallet has several advantages.
  • the pallet can basically be assembled without use of welding of the individual parts/elements.
  • the foot of the pallet is because of internally vertical support elements able to resist the pressure from the wheels that are at the end of the fork arm of a pallet lifting device, and the foot is also made as a from both sides slightly sloping skids, so that it does not make any great resistance when the wheels run over it.
  • the foot is furthermore rounded on the under side so that it slides easily across an uneven surface.
  • the pallet can be built with different strengths by insertion of more or less U-profiles, reinforcement sheets at the sides of the carrier surface, an reinforcement profiles in the legs and/or insertion of extra profiles in the lock bars.
  • the pallet can be built in a version which is usable in places where a good or high demand for hygiene is present, and furthermore is the pallet because of its low net weight very suitable for goods that are to be transported by air, and also in connection with all other ways of transportation.
  • As the outermost layer of the hollow structured sheet material of the pallet can be made in several colours this provides the possibility to use this as identification of the maximum load of the pallet or other group classifications.
  • the self adhesive markings that can contain different information, just as these information could be printed directly on the surfaces for example by the way of silk printing and preferably before the outer sheet of the carrier surface is folded to its finished form.

  • the sheets 24 can be carried out in a larger width if considered necessary. In the shown embodiment six sheets 24 have been inserted, whereby the foundation of the carrier surface of the pallet is protected against impacts from the fork arms, both if these come from the side or from the end of the pallet.

Abstract

Cette invention concerne une palette dont la surface portante supérieure (1) se compose d'éléments de préférence faits d'un matériau creux structuré en feuille et renfermant un noyau de mousse rigide, comme du polystyrène ou polyuréthanne. La surface portante est entourée et maintenue sur sa circonférence par un système de liens (8) disposés sur ses côtés. Les liens composant ce système (8) ont, de préférence, la forme d'une bande plate ou ont, dans un mode de réalisation particulier, un profil circulaire. Des canaux sont prévus dans la surface portante pour recevoir des barres de sûreté auxquelles sont fixés les pieds de la palette. Cette construction offre plusieurs avantages du fait de son faible poids, de sa simplicité et, donc, de sa résistance. Suivant le choix du matériau employé, cette construction peut être utilisée pour fabriquer des palettes d'une résistance donnée, des palettes de faible poids, ainsi que des palettes ayant une grande capacité de charge. Dans un mode de réalisation particulier, la surface peut également être faite d'un matériau lisse, particulièrement lors d'opérations nécessitant une certaine hygiène.
