Description

Pressed pallet and stack of pallets

Technical field

BACKGROUND OF THE INVENTION The present invention relates to a molded pallet, in particular a universal molded transport pallet with a support surface for receiving a transported product or a package thereof, which is made of molded cardboard or molded shavings or molded sawdust, and stacked.

BACKGROUND OF THE INVENTION

A variety of flat transport pallets are known in the art. Among the best known are universal standardized pallets, which are known as EURO pallets. These pallets are usually made of wood.

Also known are pallets which are manufactured in standardized dimensions equal to or similar to EURO pallets, which are manufactured as molded from extruded cartonboard, molded shavings and molded sawdust. The advantage of these pallets is that they can usually be pushed together, so they can be transported in a stack that takes up less space than conventional wooden EUROs.

However, the molded pallets have one major disadvantage, namely that they have walls with rough and uneven surfaces, which means that when they are inserted into the stack with their blocks, it is very difficult to separate from the stack, and it may happen that separation without breaking the pallets . It should be added that the blocks have to be designed with a certain slope for technological reasons. Such a pallet is known, for example, from DE 2 91 91 573.

This technical problem is partially solved so that the inclined side walls of the blocks

are made of small stepped steps. Such a pallet is known from the patent document CS 18

Another possible solution to the technical problem is that the individual blocks are arranged asymmetrically on the pallet. However, asymmetrical placement of the blocks means unsymmetrical support of the bearing surface, which implies that such

Even pallets have reduced load capacity. Such a pallet is known from the patent document CZ PV 1995-3448.

It is clear from the above prior art that there are a number of disadvantages of the prior art, with the most prominent being that stacked pallets are stuck together and cannot simply be split without damage, or have to be transported in small stacks, eliminating one their advantage, which is the reduced demand for transport space.

It is an object of the present invention to design a molded transport pallet which will not be limited in its load carrying capacity and will be stackable without the risk of jamming and subsequent damage.

SUMMARY OF THE INVENTION

These drawbacks are largely overcome and the objects of the invention are fulfilled by a molded pallet, in particular a molded transport pallet comprising a support surface and at least four support blocks, which is made of molded board or pressed shavings or molded sawdust, in particular molded transport pallet with uneven surface. The invention is characterized in that it comprises at least two asymmetrical support blocks, which are axially arranged with respect to the axis of the pallet, and comprise indentations arranged asymmetrically with respect to the axis of the pallet. The asymmetrical shape of the blocks means that the two adjacent pallets can be mutually arranged when inserted into the stack so that they do not substantially touch the inclined side faces of their blocks, so that adjacent stacks cannot be jammed when stacked. The advantage of the indentations is that when the two adjacent rtsr pallets are rotated relative to each other, the upper pallet ^r always abuts the step formed by the indentation of the lower pallet support block, whereby their contact is substantially planar and cannot be jammed.

For production reasons, it is very advantageous if the asymmetric support blocks are identical in shape.

In a most preferred embodiment, the molded pallet has a four-sided shape, with one asymmetric support block being provided at each corner. Such an embodiment is simple to manufacture, strong and stable, and is universally applicable.

Furthermore, it is advantageous if the support surface comprises reinforcing indentations which are arranged symmetrically to the axis of the pallet.

For production-technological reasons, it is advantageous if the asymmetric support blocks have conical side walls.

From the perspective of the highest possible load-bearing capacity of the pallet, it is also advantageous if the recesses are horizontal bearing surfaces.

Advantageously, the molded pallet may comprise at least one further symmetrically formed support block, which further increases its strength and stability.

These drawbacks largely eliminate and the objects of the invention are fulfilled by a stack of the aforementioned pallets, according to the invention, which consists in the fact that the individual closest pallets placed on top of each other are arranged with a 180 ° rotation in a horizontal plane. The advantage is that, when inserted, the shape-identical locations of adjacent pallets do not touch.

The individual closest pallets disposed one upon the other, preferably, abut with their abutment surfaces of the asymmetric abutment blocks and the indentations of the asymmetric abutment blocks. The advantage is that the adjacent pallets touch each other with their planar faces, so that they cannot get stuck together

The main advantage of the pallet and the stack of pallets according to the invention is that it is possible to stack the pallets to a considerable height, without the risk of jamming, into large stacks, which are more transportable because they take up less space. The advantage is also that the pallets have symmetrically arranged support points, which means that they are evenly loaded. The pallets are also designed for trouble-free handling of the forklift truck.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail with reference to the drawing in which: FIG. 1 shows a bottom view of a shaped pallet; FIG. 2 shows a side sectional view of a stack of three pallets; FIG. Fig. 4 is a partially sectioned perspective view of two stacked pallets.

The molded transport pallet (Fig. 1) comprises a support surface 3 and nine support blocks 1,2,13, being made of molded cardboard or molded shavings or molded sawdust. The walls of the molded transport pallet have an uneven surface.

The molded transport pallet has a four-sided shape, with one asymmetric support block 2 arranged in each corner 8, the pallet comprising two pairs of asymmetric support blocks 1,2 and further comprising five additional symmetrically formed and symmetrically arranged support blocks 13.

The two pairs of asymmetrical support blocks 1,2 are arranged axially with respect to the axis 7 of the pallet 4, the asymmetrical support blocks 1,2 having asymmetrically arranged with respect to the axis 7 of the pallet 4, recesses 5,6 which form horizontal bearing surfaces 11,12. The two support blocks 1 arranged at one of the longitudinal sides of the pallet 4 are arranged asymmetrically such that from the front view their indentations 5 are made in a directionally identical manner to the indentations 6 of the blocks 2 arranged at the other one of the longitudinal sides of the pallet 4.

All four asymmetrical support blocks 1,2 are identical in shape.

The supporting surface 3 comprises reinforcing indentations 9 which are arranged symmetrically to the axis 7 of the pallet 4.

The asymmetric support blocks 1,2 have conical side walls 10.

The stack of the aforementioned pallets (FIG. 2, FIG. 4) is arranged such that the individual closest pallets disposed thereon! they are arranged with a 180 ° rotation in the horizontal plane (Fig. 3).

Individual closest pallets placed on top of each other! abutting with their abutment surfaces 14 asymmetric abutment blocks 1.2 and abutment surfaces 11.12 formed by recesses 5.6 of asymmetric abutment blocks 1.2.

Industrial applicability

A molded pallet according to the invention, in particular as a full-fledged transport pallet for the transport of any objects or their packages.
