DESCRIPTION:
BRIEF SUMMARY
The invention relates to an apparatus for carrying loads, particularly to a pallet.
Pallets are frequently used throughout the world. Therefore, a detailed description of known techniques in general is not necessary.
A drawback with known pallets resides particularly in that handling of same, i.e. transport, packing and storing, often is very costly. It goes without saying, that e.g. relatively small pallets entail numerous operations, as they are to be produced, transported, packed and stored as such.
The objective of the present invention is to render production as well as transport, packing and storing of pallets in particular as economical as possible. It is furthermore an objective of the invention to improve and develop previously known pallets as well as parts of same in various technical respects.
These objectives are achieved according to the invention by an apparatus for carrying loads, particularly for or at a pallet, which apparatus is designed as revealed by the characterizing clause of claim 1.
Further characteristics of and advantages with the invention appear from the following specification with reference to the accompanying drawings showing some embodiments, partly in diagrammatic views, which embodiments are to be regarded as non-limiting. In the drawings,
FIG. 1 is a perspective view of an apparatus for carrying loads designed as a spacer,
FIG. 2 is a plan view of the spacer according to FIG. 1,
FIG. 3 is a side elevational view of a modified embodiment of a spacer according to the invention,
FIG. 4 is a plan view of the spacer according to FIG. 3,
FIGS. 5-8 are plan views of various diagrammatically shown pallet embodiments using spacers according to the invention,
FIGS. 9-11 show various embodiments of pallets according to the invention in perspective views from above,
FIGS. 12-14 show a perspective view from below, a side elevational view and a perspective view from above of a further embodiment according to the invention,
FIGS. 15-17 show a perspective view from below, a side elevational view and a perspective view from above of a further embodiment according to the invention,
FIG. 18 is a perspective view of a spacer according to FIGS. 12-14,
FIG. 19 is a perspective view of a spacer according to FIGS. 15-17, and
FIG. 20 is a plan view of the spacers according to FIGS. 18 and 19.
Each embodiment of the invention comprises a pallet having an upper side in the form of a load platform 21 and a lower side in the form of lower runners 22 extending parallel to opposite side edges of the upper load platform. The runners are spaced from the platform by spacers made according to the present invention. The platforms 21 are angular with corners which are designed to mate with complementary corners of a laterally-adjacent platform.
A spacer according to the invention as shown in FIGS. 1 and 2 comprises two cylindrical bodies 2, 3 with their axes in parallel and their peripheries in abutting relation to each other. The spacers are preferably made of wooden chips by presscasting.
According to another feature of the invention, such a pair of spacers is held together by a so called shrink film 4, which preferably is relatively thick, e.g. having a thickness of 10.mu.-200.mu..
According to the alternative 5 shown in FIGS. 3 and 4, there are also provided two cylindrical bodies 6, 7 which, however, are not abutting each other with their peripheries but are interconnected via a bridge 8. Furthermore, the bodies 6, 7 show preferably throughgoing central openings 9, 10. Even this embodiment can be produced by presscasting, preferably, however, it is made of a more durable material with e.g. plastic material or combinations of plastic material and/or fibers and chips respectively. Even pressed fibrous material of various kinds can be considered.
According to the invention, each pallet will not be produced separately. Instead, at least two, possibly even three, four or more pallets are produced simultaneously with the pallet sides abutting each other showing pairs of spacers, the interconnectors 4, 8 of
