Plastic loading pallet

The invention relates to a loading pallet made of plastic, the loading area and feet of which are made in one piece are shaped and which can be driven under from all sides with forklift forks.

There are already known loading pallets which consist of a body pressed in one piece. Are to the actual loading area thereby molded hollow feet and reinforcing ribs. It has also been suggested that the loading area be concentric with reinforcement arranged, circular grooves to be provided. The strength achieved in this way is indeed improved compared to flat pallets, overall, however, still inadequate because deflections occur in the annular grooves under load. At a Another embodiment, the feet of the pallet are connected to side bars and the surfaces between the feet are supported with diagonal bars, which bear upwardly directed counter pressures at their crossing points. Also here there is a risk of bends, especially in the edge zones and with uneven loading. According to another suggestion the entire stacking plate is divided into four symmetrically arranged areas, via the diagonal reinforcement ribs run, each of which merges two from adjacent surfaces are. In this way, the stacking surface is divided into a V-shaped pattern with the ribs of the main diagonal converge in the middle of the plate. But even this arrangement of reinforcing ribs does not give the pallet such strength in all zones that bending under load and pressure apart of the ribs when lifting under load is required Dimensions would be avoided.

This resulted in the object underlying the invention to create a loading pallet that can be manufactured from one piece so economically that it can be used as a one-way pallet, with high strength and large 253/69 ^^. _c r ^ lZ -2-

Has flexural resistance and which extends from all sides with forklift forks lets go under.

This object was achieved according to the invention by means of a plastic loading pallet solved, the ribbed reinforced loading area and the feet are molded in one piece by the top the loading area is formed from uniformly lying in the longitudinal direction of the pallet, bar-shaped ribs and in alternating Follow between the upper ribs after the underside of the pallet in the same direction through drawn-in interruptions Shortened rib sections are pulled out, which are in the pallet feet and in two transverse ribs lying between the center feet come in.

The loading pallet according to the invention can consist of a plastic film web Manufactured extremely economically in one operation, for example by deep drawing, and therefore as a one-way pallet be used. Due to the alternating sequence of a long, bar-shaped rib on the top of the loading area and the one in the same Shortened reinforcing ribs running in the direction of the underside with a subsequent bar-shaped top rib etc., there are practically two contiguous, rust-like surfaces, which are only caused by the further pulled out Feet are interrupted ^. Mainly shows lengthways the loading pallet is very stiff and flexible. But also in the transverse direction, the resolution of the Underside of the pallet continuous ribbing in short rib sections and through the drawn-in interruptions, the one Form a large number of webs lying in the transverse direction, a high level of strength is achieved. If you further consider that when driving under On the loading pallet, the forks usually extend from one side to the other in the transverse direction, then there is no danger deflection also in this load case, because then the strong, bar-shaped ribs the resulting bending forces take up.

In the case of particularly heavy loads, according to the invention, it is possible Continuous reinforcement profiles extending over the entire loading area at several points between the bar-shaped ribs

to use. This becomes a very significant one in a simple manner Increased strength achieved for the entire loading pallet, which is not the case with the known cross, ring and angle ribs is possible.

The reinforced design of the edge of the loading pallet according to the invention is also of particular advantage. After that is the whole Provided all around the edge with alternately drawn-in and drawn-out stiffeners, which particularly accumulate at the points where the feet are pulled out. In addition to increased strength of the outer edge, this prevents the feet from being under the Break in the load of the load. In addition, there is a criss-cross longitudinal and transverse ribbing in the feet themselves, which is sufficient Brings stability to the fully loaded pallet.

With extreme loads on the loading pallet, the cavity of the feet can also be filled with foam, foam-cement or the like be poured out or stiffening parts can be used in the feet from the manufacture of the pallet for such needs being.

The edge stiffeners on the narrow sides of the loading pallet can also be rounded on the underside and the outer one The edge of the pallet can have a semicircular breakthrough, so that, if necessary, the underside of the pallet can be inserted at each end Transport spar can be inserted “To move loaded pallets when the crane is in operation, it is then possible to use the chains of the crane lifting gear to be attached directly to the transport bars. This is of great advantage in port traffic because it significantly increases the loading costs to decrease.

According to the invention, loading pallets can be produced that can be used economically as one-way pallets and that have the particular advantages of great stability, low weight and absolute weather resistance, and those for stockpiling can be stacked one inside the other. The same according to the invention can be used for the storage and transport of particularly heavy loads Loading pallet can be made more load-bearing by additional, easy-to-use reinforcement parts, so that

an advantageous use of practically one and the same pallet is given in several load classes.

The following is the pallet according to the invention based on the Drawings schematically illustrated embodiments explained in more detail. Show it:

The rectangular loading pallet 1 is molded in one piece. |, For manufacture in deep drawing, vacuum or blow molding processes all suitable plastics are used. The upper side 2, which represents the loading area, is uniform according to FIG Bar-shaped upper ribs 3 extending in the longitudinal direction of the pallet are formed. The bottom 4 of the pallet (Figure 2) is made from running in the same longitudinal direction, shortened by drawn interruptions 5 rib sections 6, 6 .In one piece that belongs together follows every long, bar-shaped, upper rib 3, which in their entirety form the pallet loading area, each with a reinforcing rib 6 running in the same direction on the underside of the pallet 4 (FIG. 2) with the following again bar-shaped top rib 3, etc., so that the overall cross-section is composed of a large number of contiguous U-shaped individual cross-sections. The shortened ones Reinforcing ribs on the underside of the pallet have partly straight base surfaces 6, partly curved base surfaces 6 ', which overall contributes to the solidification. A lateral stabilization is further caused by the drawn-in interruptions 5, which are arranged at the same distance and thus practical Form transverse webs over the narrow side 7 of the pallet. the

"Both grate-like surfaces of the top 2 and the bottom 4 are only interrupted at the points where the feet are pulled out. Three such feet are arranged at equal intervals in the central axis and on the edges of the pallet and connected by strong crossbars 9, so that the pallet can be driven under from all four sides with forklift forks. All feet are stiffened by longitudinal ribs 10 and transverse ribs 11. In special cases, the cavities 12 of the feet can be filled with a solidifying compound or prefabricated stiffening parts can be used in the manufacture of the pallet the feet are used.

For easy adaptation of the loading pallet to special load cases Continuous reinforcement parts 13 can be used at two or more points between the bar-shaped ribs 3 (Figure 3), which extend over the entire length. For this purpose, there are a corresponding number of ribs 60 on the underside of the pallet pulled through without interruption. In FIG. 4, a reinforcement part 13 is seated in the continuous underside rib 60 and finished with the surface of the upper side ribs 3.

The edge 14 of the pallet has a circumferential inner reinforcement 15 provided, from which additional reinforcements 16, especially on the feet 8, are pulled out after the underside 4. On the narrow sides 7 of the pallet, the edge stiffeners 16 can be rounded on the underside (FIG. 5) and the outer pallet edge is then provided with a corresponding, semicircular opening 18. This results in a continuous over each narrow side Support 17, in which a transport bar 19 can be used (Figure 6). In crane operation, loaded pallets of this type can be effortlessly and inexpensively move, because the chains 20 of a normal crane gear to attach directly to the protruding parts of the transport bars 19 are.
