Description

The invention relates to a pallet made of four folded, essentially identical material blanks, e.g. made of corrugated cardboard, the successive and have sections separated from one another by bending lines and to one another by plug connections are attached.

It is already a flat sheet consisting of four corrugated cardboard blanks Transportable pallet from the German that can be put together on the spot by the user Patent 1,250,352 is known. The finished pallet has the shape of a bar lattice in plan crossing bars are open at the front. As a result, the resilience of the known pallet is just im outer peripheral area severely restricted, where it is known for every asymmetrical load Forces occur which are the measure of the average wing loading on a level surface far exceed the resting, loaded pallet. Such asymmetrical load cases can be found in Never completely avoid moving pallets with the help of forklifts, for example.

Another disadvantage of the known pallet is that it is because of its lattice-like Floor plan cannot be used for every type of goods.

The invention is based on the object of creating a pallet of the type mentioned that can be used on all sides is closed and stable, so that it can be transported with goods of any shape and size (within the scope of their Dimensions) and can be particularly heavily loaded at their edges.

According to the invention, this object is achieved in that each has a first web section, one Cover plate section, a second web section, ίο a fold-back section and a third web section having material blanks together form a flat hollow body, the continuous Surface of the cover plate sections of two abutting material blanks, its Undersurface of the cover plate sections of the other two, also abutting one another Material blanks that are offset by 90 ° to the first two material blanks, its four side walls are formed by one of the second web sections each of a material blank and the spacers intersecting in its interior, each of two of the first and third web sections are formed.

This gives the folded pallet not only one that is closed on all sides and on the edge particularly heavy-duty structure, but also has stiffeners inside, so soft are designed that they are supported by the prongs of a

applied forklift to absorb and pass on outgoing forces.

Advantageously, openings prepared by means of interrupted cutting lines can be made in the web sections For fork legs of a forklift or the like. Be arranged, which are when retracting the fork leg tips Divide it in the middle like a gate leaf and swing it inwards so that it is perpendicular to it the support layer extending to the cover plate sections is retained.

In this way it is achieved that the load-bearing capacity of the entire pallet even after entry of fork legs or the like. Is fully preserved.

The prepared openings for fork legs are designed so that the pallet before its first time Use is closed on all sides; this is especially beneficial when having the pallet stacked on top of it Goods to be covered with a film or the like. If you drive a forklift from any Side up to the pallet, so the film including the prepared openings is applied to the pierce the designated places.

To increase the accuracy of the approach, the separation points between the gate leaves can be cut through each a hole or the like. Be pre-marked.

An embodiment of the invention can the following description with reference to the drawing can be taken. It shows

Fig. 1 shows a single material blank for a Palette,

2 shows a section of a similar material, but on an enlarged scale and with a prepared perforation in the division area of gate leaves,

3 shows a perspective illustration of an individual phase when putting the pallet together, with three already partially assembled and partially angled painterly cuts,

4 is a perspective view of the partial cut and ready-folded pallet

with gate leaves in a side wall formed under the action of retracted forklift spars.

The pallet consists of four identical material blanks 10, one of which is shown in FIG. 1 is shown in the stretched-flat state. The material cut 10 has a square basic shape with two continuous side edges and two with slots 24 marked front edges. The cut is made up of four continuous pieces running parallel to the front edge Bending lines 21 divided into five sections, specifically in the illustration of FIG. 1 from below upwards into a web section 13, a cover plate section 11, a web section 15, a fold-back section Ι? and finally a web section 17 again.

All?; Epelinien 21 include two interrupted ones Cutting lines 22, and the web sections are at the level of the interruption of the cutting lines 13, 15 and 17 also interspersed with interrupted ao cutting lines 22, which are parallel to the Side edges of the materi? ^ section 10 run.

In addition, runs parallel to the side edges in the course of an imaginary center line of the material blank 10 a slot 23 half the width of the as Web section 17 and through the fold-back section 19 to the next bending line 21; the The width of this slot 23, like the width of the other slots 24, is approximately twice that Material thickness of the blank 10. This is z. B. made of double-walled corrugated cardboard.

To produce the pallet, four identical material blanks 10 are plugged together in the folded state. In Fig. 3 a phase of the pallet production is shown schematically. The ZusammensU CKEN and creases running approximately as follows: First, the two web portions 13 are of a first Malerialzuschnitts 10 a and a second material blank 10 b 9 (P folded and placed against one another α The material blanks 10 and 10 b form a first cut pair then.. the web section 17 c of a third material blank 10 c is angled by 90 ° and, as shown in FIG , while the folded-back section 19 c rests parallel on the rear sides of the cover plate sections 11α and life.

In the same way, but with mirror symmetry, the fourth, shown in FIG. 3 not yet shown material blank 10 c / placed. Now the two web sections 15 η and 15 b are raised at right angles to their adjoining cover plate sections 11 α and 11 b , then the fold-back sections 19 a and 19 ft are angled at right angles to this and the web sections 17 a and 17 6 attached to them are again angled downwards by 90 until their Stirnkai.ten perpendicular to the deck plate portions 11a and lib and collide with them. In this way, two hollow box profiles are created, which are delimited on the outside by the web sections 15 α and 15 Z '. Here, the slots 24 "of official web sections 17 a to 17 d, intersecting one another.

Now only the two upstanding cover plate sections lic and 11 </ are folded and the sieving sections 13 located on them are bent at right angles and pushed with their outer sections into the slots 23 of the folds 19 a and 19 b . Here, all of the web sections 13 a to 13 d intersect in their middle, where the middle slot 24 is located.

In this way, the pallet has been put together as it is partially cut open in FIG is shown. From this figure of the drawing it can be seen how in the area of the side walls 15 a to 15 J of the pallet between two interrupted cutting lines 22 and the one above the other the center of which vertical uninterrupted cutting line 22 connects with prepared openings are that give way under the pressure of retracting fork legs 40 and form gate leaves 42, which unfold inwards while maintaining their vertical position.

On each side wall of the pallet, formed by a web section 15 α to 15 d, there are two prepared openings of this type. In addition, all of the web sections 13 and 17, which apart from the web sections 15 form the spacers of the pallet, are provided with similar prepared openings. These inner web sections 13 and 17 also fold, as shown in FIG. 4 it can be seen, under the action of the fork legs 40 moving inward, while maintaining their vertical position.

It is clear that the load-bearing capacity of the pallet, even with the gate leaves 42 open, is at least still is as big as before, as the gate leaves continue to serve as load-bearing elements. It is even with one Increased load-bearing capacity can be expected, since the web sections serving as spacers through the angled gate wing 42 have received an additional buckling rigidity.

To increase accuracy when inserting the fork legs 40 into the prepared openings can cut the material at the intended locations at which the gate leaves 42 from each other should separate, except with cutting lines 22 with a hole 26 be provided. In Fig. 2 of the drawing is a correspondingly modified embodiment for a material blank 110, which differs from the material blank only through distinguishes a web portion 115, each with a hole 26 in the area of each prepared opening is provided. The other details of the material blank 110 are unchanged and so far in Fig. 2, provided with the same reference numerals as in Fi g. 1.

For the empty transport, the four material blanks 10 or 110 required for a pallet are im flat state placed on top of each other and packaged. After use, it is possible to use the To dismantle the pallet again into its individual material blanks 10 or 110, to store and / or pack them.

The smooth outer surfaces and rounded edges of the assembled pallet are modern Particularly opposed to packaging methods. So can the pallet with the mountain of goods stacked on it for example, covered with a plastic film and welded rainproof. The enveloping Foil is simply pierced by the forklift's fork legs, without their Losing protective effect.
