DE6921220U - PLASTIC PALLET FOR CARRYING AND TRANSPORTING LOADS - Google Patents

Description

The innovation concerns a pallet made of synthetic material (plastic) for carrying and transporting loads with a grate-like supporting upper part and a lower part connected to the upper part and with lateral Walls which have openings for inserting the fork or the fork parts for lifting the pallet.

Such a pallet is used to transport loads such as boxes, cartons, sacks, etc., as well as for conveying, i.e. picking up, transporting and setting down mechanically, e.g. by means of forklifts suitable, and also allows loads it carries to be stacked in a warehouse for any length of time.

Transport elements or pallets made of wood are known. The wooden pallets have the disadvantages that they are heavy and fragile, and that they require expensive maintenance because of damage during handling and the effects of the weather. Their lifespan is therefore relatively short.

Furthermore, pallets are known that are made of synthetic

53 * 12/01 (ir / Sch '- 2 - May 27, 1969

Material, i.e. plastic, are made; These have the advantages over wooden pallets that they are lighter and more durable and do not require any maintenance.

However, the known plastic pallets have insufficient stability or stability for many purposes. Strength. They deform and often suffer material damage when they are loaded with

, of the fork (s) of the stacking machine or stacker are raised will. In addition, they are often broken as a result of forcible and inaccurately aligned insertion of the fork or abelteile of the truck.

After all, the production of the known plastic pallets is tedious and expensive: it includes that Forming the supporting upper part and the lower part in several manufacturing stages, the assembly of the various individual parts by means of welding or by means of suitable connecting elements, the injection a filling compound, which is intended to increase the stability, and the possible attachment of anti-skid elements on or under the lower surface.

The object of the innovation is to avoid the above-mentioned disadvantages of the prior art and thus to create a pallet which is particularly easy and cost-saving to manufacture and which one sufficient strength and insensitivity to material damage and thus a long service life having.

The innovation solves this problem on a pallet of the type mentioned in that the grate or the ribs forming the grate extend downwards from the surface of the pallet only over part of the height of the pallet, such that a completely free space is created for the entry of the fork or fork parts.

The new range consists of synthetic Material (plastic), for example made of polyethylene, polyvinyl chloride (PVC), polyamide-alpha-buthylene-styrene (ABS), polyester with or without reinforcement inserts or made of plastic Zeil material, these materials according to the injection molding process, the simple die casting process, processed by molding or polymerisation "in situ" or by firing to produce the pallet can be.

The. Reinforcement is advantageously achieved by means of Plates that are connected to the grate to form a single body, e.g. in one piece, and formed or formed in one piece with it. are cast, and thus serve to increase the stability of the element.

Dai carrying and transport element or the pallet according to The innovation also has large openings in the side walls that allow easy entry of the fork for lifting enable and which are extended over a certain distance into the body of the element by means of Sliding plates, which form passages, the cross-section of which is becoming increasingly smaller (towards the inside), but which also ' Even at its smallest point, a sufficiently large opening for the fork or the fork part to pass easily through having. This construction is particularly suitable, for example, in department stores, warehouses, department stores Or the like. Where it is important to use the storage space to the maximum without the maneuvering of the forklift is hindered.

Another advantage of the range according to the innovation is its simple production, which takes place in two stages takes place, which has a favorable effect on manufacturing costs: During the first stage, one forms and / or casts each in a single work process separated from each other according to a known process (e.g. injection molding process, molding process, Sintering process, etc.) the upper part with the

bearing surface and the lower part, while in the second stage the two parts are connected to one another with a known welding operation. Further features and advantages of the innovation can be found in the following description. An exemplary embodiment is shown in the drawing. The individual figures of the drawing show:

Fig. 1 is a side view of the element according to the innovation,

FIG. 2 is a plan view of the element according to FIG. 1,

3 shows a section according to A-A of FIG. 2,

4 shows a section according to BB in FIG. 2,

Fig. 5 shows a section according to CC of Figure 2,

6 shows a section according to DD in FIG. 1.

In the individual figures of the drawing, the same reference symbols have been used for identical or similar parts used.

The supporting upper part of the pallet is denoted by reference number 1. This part comprises a grate 6 with square or rectangular or differently shaped meshes, which are formed by ribs 3 , which extend down to about a middle height of the pallet (from the top) .

At the points of greatest stress, namely above the two openings 8 (FIG. 1), the grate is reinforced by the plates 7 (FIG. 3), which are connected to the grate to form a single body, and which give the entire pallet great strength to lend.

The peripheral and middle ribs 5 (i.e.

53 ^ 2/01 Gr / Sch - 5 - May 27, 1969

the outer and middle walls of the pallet) have a greater depth than the ribs 3 and together carry the Lower part 2 of the pallet.

The two large openings 8 allow easy insertion of the fork, for example a forklift. These openings are extended over a certain distance into the interior of the pallet by means of vertical sliding plates 9 and suitable sliding plates 10 (Figure k) , which form passages, the cross-section of which is increasingly reduced (in the direction of the inside of the pallet) and the entry of the fork or a fork part allows. These sliding plates ensure that the fork or the individual fork prongs are precisely positioned before lifting and avoid damage to the pallet if the fork or the fork parts are too high or too far to the side.

The lower part 2 (FIG. 1 and FIG. 6) comprises a plate which is provided with four large openings 11 and which is suitably designed to enable the loaded pallet to be transported by means of a cart. The peripheral and central ribs 5 'merge with the corresponding ribs 5 of the upper part.

The plastic pallet according to the innovation points to the known state of the art has numerous and significant advantages:

1. Low weight: with the same loading capacity, it weighs only about half of a known transport element of the same type.

2. Great stability: it allows heavy loads to be transported without damaging deformations.

3. Long lifespan; due to high impact insensitivity.

k. Economical production, which only Two stages of manufacture include: molding and pouring of the upper and lower part and subsequent joining of the two parts by welding.

5. Easy insertion of the fork or the fork prongs to lift the pallet, whereby the large openings and the sliding plates facilitate insertion.

Also located below the level of the ribs 3 of the upper part and in the space 11 between The sliding plates do not have any parts that might hit and damage as a result of the fork being inserted could become.

The transport element according to the embodiment described above has two openings; Of course Embodiments are also conceivable as part of the innovation, which have a larger number of openings, for example four openings.

Another embodiment of the innovation can arise in that two identical tops are attached to one another the ribs 5 are welded. This creates an inverted pallet that can be used on both sides.
