Definitions

  • the present invention concerns a board with cellular structure, which board comprises a core of cells located adjacent one another, which cells on both sides are covered by a cover layer or panel in order to constitute a load bearing or supporting surface.
  • Such board can be used as e.g. the load bearing surface of a pallet, as described in WO-A-83/01 243.
  • Pallets for storage and transport of goods must satisfy a plurality of requirements. They must be light, cheap to produce, possess great structural strength and rigidity against torque and in many cases be easy to clean and hygienic in other respects for e.g. transportation of foodstuffs.
  • pallets of wood are unhygienic, as the wood attracts moisture and thereby causes mould.
  • nooks are formed, within which dirt and germs may collect.
  • Pallets of wood are also difficult to make and keep clean, which fact has contributed to attempts to manufacture pallets from some other, lighter, stronger and more hygienic material.
  • a loading pallet which is made of a wooden frame, transverse wooden strips, a loading surface of cardboard, pasteboard, masonite or wood and a honeycomb material made of pasteboard or cardboard stretched inside the wooden frame.
  • the honeycomb material acts as a distance material and the pallet is manufactured by glueing the parts together.
  • the French Patent 2 389 485 discloses a board with cellular structure comprising a core of cells located adjacent one another and being hermetically sealed. However, the cells are separated from each other and do not support each other. Such a board has only a resilient function and the whole construction is a resilient and flexible cloth used as protective packaging material in order to protect sensitive goods from damage.
  • the described pallets with cellular structure have, even if they should be produced for multiple use, several drawbacks.
  • the structure with individual casings or assembled creased strips results in that the consumption of material becomes large and that a pallet of plastic material built up in this way and destined to endure multiple utilization obtains increased weight and, therefore, becomes expensive in manufacture and use.
  • the application of cardboard as material for the pallet provokes, on the other hand, the same problems as wood material when the hygienic aspects are in consideration, for example.
  • the known pallets for which cardboard or paper has been proposed as material form due to their composition of a plurality of casings or creased layers a great number of cavities and/or nooks, within which dirt, germs etc. can accumulate.
  • these pallets are best suited for single use and can in no way be compared with pallets of wood or cast, armoured plastics, which shall be usable repeatedly as pallets of exchange inspite of the rough treatment to which they often are subjected.
  • the main object of the present invention is against the background of the above to provide a board with cellular structure, which can be used as e.g. load carrying panel in a pallet for multiple use, wherein the aforementioned drawbacks inherent to known pallets made of both wood, cast plastics or with cellular structure are eliminated totally.
  • Another object is to provide such a board which is especially suited to be manufactured from a light and relatively cheap material and with a shape which renders it extremely utilizable in response to highly advanced hygienic demands.
  • Figure 1 shows in a perspective and partly sectioned view a pallet of plastic material, in which pallet is included a board with cellular structure according to the invention.
  • Figure 2 shows in a perspective view a bottom part which is an integral part and acts as support member in the pallet according to Figure 1.
  • Figure 3 shows in a perspective view another shape of a support member for the pallet of Figure 1.
  • Figure 4 shows a side view of the one longitudinal side of the pallet.
  • Figure 5 shows a side view of a short side of the pallet.
  • Figure 6 shows on a larger scale an encircled detail of the pallet of Figure 5.
  • Figure 7 shows in a perspective view the pallet of Figure 1 seen from below.
  • the shown pallet comprises a load carrying board or core 10 with cellular structure.
  • the cells have here multiple edge shape, preferably as in the shown embodiment, hexagonal shape and form a honeycomb structure, which extends over the entire surface of the load carrying board.
  • every cell 12 has walls 14 which are common, i.e. in one piece with the walls 14 of the surrounding cells.
  • the cells are here not formed by casings or creased bands or strips, but all cells 12 are integrated to a unitary structure without any joints.
  • an elastic i.e.
  • cover layer 16, 18 on both the bottom side and the top side, which cover layers 16, 18 are connected to the cellular structure 10 in such a manner that every cell 12 becomes individually sealed hermetically.
  • This joining between cover layers 16, 18 and cellular structure 10 is effected in a suitable way, welding as is known in the art of shaping plastic articles.
  • Every cell functions as stay member and supporting part for the whole cellular structure 10, since the cells are integrated with each other, i.e. united into a coherent entirety, and every cell functions also, owing to the enclosed air cushion, as a shock damper and shock absorber.
  • the enclosed air cushion and shaping of the cell structure 10 from an elastically yielding material causes also that the cellular structure 10 when subjected to shocks or spot load, is not cracked, but yields resiliently and recovers its original shape when the load disappears.
  • the described cellular structure 10 involves also that the load carrying board obtains very high strength against twisting forces and thus is considerably more rigid against twisting than previously known constructions.
  • the upper cover layer 16 of the board represents preferably, as is shown in the embodiment depicted in the drawings, the upper cover of the pallet, and in this connection the top surface is formed with grooves 20, which conduct possible moisture and water formed therefrom to draining holes 22 disposed at the centre and corners of the pallet.
  • the cover 16 is also, as is evident from the embodiment shown in the drawing, provided at its longitudinal and short sides with depressions 28, 30, which also are provided with draining holes 32, 34.
  • an edge border stip 24 Arranged around the periphery of the pallet is an edge border stip 24 which seals the cellular structure 10 along the sides and is fixed thereto by means of glueing, welding or similar jointing means, preferably the same which are used for securing the cover 16 to the cellular structure 10.
  • the edge strip 24 projects a bit, such as by 5 mms for example, over the cover 16 and constitutes hereby an all around extending list 26.
  • This list 26 makes the pallet well adapted for piling without any risk that the piles of pallets should come down.
  • the list 26 involves also that goods not so easily slide away from the pallet.
  • support members for the pallet have the shape of two brackets 36 (see Figure 2 also), which have a support base plate 38 disposed to rest on a base and three raised portions 40, which are devised to be secured to the underside of the cellular structure 10 onto the lower cover layer or deck 18.
  • the brackets 36 are welded onto the top part to form a unit therewith.
  • openings 44 Provided between the raised portions of the brackets are openings 44, see Figure 4, into which it is possible to introduce lifting members for lifting the pallet, such as, for example, the lifting forks (not shown) of a piler truck.
  • the brackets 36 have in the raised portions also draining holes 46, which are in connection with the draining holes 22, 32 in the upper cover 16. It is clear that a corresponding drainage is provided through the cellular structure, e.g. by tubes (not shown) passing therethrough.
  • additional support members 48 and a support plate 42 which have draining hole 34 and 50 respectively, the last-mentioned connecting through the cellular structure 10, which has been described above, to the holes 34 in the cover 16.
  • additional support members 48 and a support plate 42 which have draining hole 34 and 50 respectively, the last-mentioned connecting through the cellular structure 10, which has been described above, to the holes 34 in the cover 16.
  • openings 52 for introduction of lifting members which have been described above.
