Description

15th

The invention relates to a flat pallet for piece goods, consisting of provided at the corners Support feet and one directly receiving the load Cover plate, which is stiffened by edge angles and surface arching.

In their basic form, those commonly used for transporting and / or storing piece goods of all kinds Mostly square or rectangular pallets are used in industrial plants, warehouses, in freight transport and otherwise for the transshipment and storage of operating materials and transport goods, always in larger number is required. One has always tried to make the pallets as simple as possible and also the Maintenance and repair work associated with their transport cycle, if possible to keep it low, without, however, on the other hand, again undesirable loss of usefulness and having to accept service life. Out of these J5 endeavors arose among other well-known ones Finishes the pallets made exclusively from metal.

It is from US-PS 18 76 807 an all-metal Plarh pallet with support feet provided at the corners, in which the cover plate is formed by molding bead-like bulges in straight parallel rows over practically their entire Surface is stiffened. The stabilizing effect that can be achieved in this way, however, remained predominantly in a direction transverse 4ί limited to the bulges, while on the other hand the corrugated sheet-like surface structure of the Cover plate often turned out to be a nuisance and inexpedient, and attachment was an inevitable remedy a cover plate, in turn, the disadvantage of higher> o Manufacturing costs and higher final weight resulted.

In contrast, the object of the invention is a novel design of the cover plate in flat pallets, which this the desired dimensional stability under "> '> waiver of the use of additional construction elements and without restrictive concessions to the universal applicability and the serviceability who lends pallets.

To solve this problem, the all-metal flat pallet of the type mentioned at the beginning provides that the cover plate is arched downward in the form of a flattened pyramid with formed obtuse-angled folds converging diagonally at its center. <■ ·

The pallet according to the invention not only enables considerable cost savings in its manufacture, it also has surprisingly favorable effects on the use value that could not be foreseen of the pallets. Because the kink folds as a replacement for stiffening ribs that would otherwise have to be welded on in the intended surface pattern in its entirety with a single pressing process into the If the floor pan is formed, the production of the new pallets can be clearly mass produced economically design in large numbers in a previously unattainable degree. The over the whole The surface of the floor pan also has creases running diagonally through it heavy loads, sufficient dimensional rigidity and torsional rigidity, without any restrictions in is subject to the direction and also not the effect achieved with comparable known means is inferior

It is true that they are all-metal pallets with a cover plate that is also curved like a pyramid known (US Pat. No. 3,776,435). These known pallets are only used for picking up Flowable cargo, the cover plate itself being designed as an outlet funnel and with an outlet regulating active closure member is provided on the design of pallets of the present type for The funnel shape of the cover plate cannot be used for the transport of piece goods.

However, the invention also has particular advantages in practical use. The in the form of a comparatively blunt, flattened pyramid arched downwards between the feet When picked up by a forklift, the cover plate offers two lifting forks in each direction smooth lateral inclined surfaces, which on the one hand prevent accidental slipping and on the other hand again have a centering effect and compensate for control errors of the incoming stacker vehicle. Conversely result from the corresponding concave bulge of the available loading area slight slanting positions of the applied goods with inward inclination, which in many cases, for example, to Stacking of pneumatic tires or similar piece goods in rows next to each other for stability of the stacked goods is very desirable.

Finally, the shape of the new pallets, which is recessed in its central area, is also advantageous for the Accommodation of the mostly existing removable supports for the return transport of the empty pallets to take advantage of. Since the support pillars laid down in the depression are already due to the effect of gravity are adequately secured against loss, it is entirely sufficient to use them instead of complex other measures for example with the help of loosely wrapped binding lines or adhesive tapes against each other as a makeshift to be determined.

To avoid accumulation of water in the central recess of the pallet with the risk of rust formation and To avoid corrosion, an open bore is provided as a further embodiment of the invention to attach the cover plate in the top of the pyramid:

The pallet according to the invention is based on the schematic representation of an exemplary embodiment illustrated in the drawing. It means

Fi g. 1 a flat pallet in perspective view and

FIG. 2 shows a cross section along the line II-II in FIG. I on a larger scale.

The pallet consists of a rectangular cover plate 3 with feet attached at its four corner points.

Ben 4. The cover plate is formed from sheet steel, for example, and has a frame S running all around U-profile steel or another rolled profile, the necessary connections to both the frame and the feet are practical are made by welding. The StandfüQe 4, which in a known manner from pipe socket with attached widened foot disks can be formed, are used once to park the pallet in a for Under the cover plate 3 by the lifting forks of stacking vehicles sufficient distance above the

Floor area and, on the other hand, at the same time for the loose insertion of supporting supports that are not shown.

The cover plate 3 hai by molding diagonally intersecting obtuse-angled folds 13 the Shape of a downward bulging flat pyramid, while vice versa the available loading area is composed of four triangles that meet at their apex and incline inwards at an angle represents. At the point of intersection of the folds 13, d. H. In the top of the pyramid, there is an open hole 6 to the Drainage of water attached
