Description

The invention relates to a stackable cargo carrier according to the preamble of claim 1 or 3. Such load carrier - also known as pallets - are known in various designs.

The object of the invention is to provide a load carrier, which is manufactured at a sufficiently high load capacity exclusively of paper and / or corrugated and / or solid board and u. a. as a once-usable load carrier is suitable for transporting and / or storing a variety of stored goods, but also up to its use with a variety of similar load carrier well stackable and easily removed when using the corresponding stack.

To solve this problem, a load carrier according to claim 1 or 3 is formed.

The peculiarity of a first possible embodiment of the cargo carrier according to the invention is that in an at least two-layered design of the support plate of this cargo carrier at least in the region of the feet each a reinforcing intermediate layer is provided, which overlaps the local foot at its anchored in the support plate upper edge and several against the inner surface of the foot folded and attached to the inner surface, for example, glued tabs forms.

The peculiarity of another possible embodiment of the cargo carrier according to the invention is that formed on the support plate underside of the material of this support plate or from the material of the lower layer of the support plate shaped tabs which protrude beyond the support plate underside, abut against the outer surface of the feet and there with the feet are connected. Through these tabs, not only the anchoring of the feet on the support plate and the stability of the load carrier is improved overall, but the tabs also form at the same time Spacer between the superimposed load carriers, by the fact that the tabs of a load carrier bear with their free ends against the upper side of the support plate of the underlying stack in the load carrier.

By the spacers formed by the outer tabs a clear distance between the support plates of the stacked, for example, for the empty transport and / or storage pallets is ensured and in particular in such a way that jamming or wedging the stacked load carrier at their interlocking feet is avoided, so that the load carrier in the case of use of a load carrier stack with suitable tools, such as a forklift can be easily removed.

a representation like FIG. 3 in a further embodiment.

The load carrier generally designated 1 in the figures essentially comprises a support plate 2 and a plurality of feet 3 provided on the support plate 2 and projecting beyond the underside 2.1 of the support plate 2.

The support plate 2, which has a rectangular blank in plan view, with dimensions corresponding to the dimensions of a conventional transport pallet, is made of corrugated cardboard in multiple layers, in the illustrated embodiment of a total of four layers 4-7, of which in the 3 uppermost layer 4, the top 2.2 of the support plate 2 and the bottom layer 7 in this figure, the bottom 2.1 of the support plate 2 forms. Each layer 4 - 7 is formed in the illustrated embodiment, each of a single-wall corrugated board. The individual layers are designed so that the waveforms intersect, for example, in the form that the waveforms in the uppermost layer 4 perpendicular to the plane of Figure 3, in the next following layer 5 in the drawing plane of Figure 3, in the next following layer. 6 3 again in the drawing plane or parallel to the drawing plane of Figure 3 are oriented perpendicular to the plane of Figure 3 and in the bottom layer. The individual layers 4 - 7 are connected by full-surface gluing together.

In the illustrated embodiment, a total of six feet 3 are provided. Each foot 3 is made in this embodiment of a solid board, in the form of a frusto-conical hollow body such that each foot 3 tapers to its the support plate 2 remote lower edge or end 3.1, with this foot and thus the load carrier 1 total gets up on a substrate. With its upper, the larger diameter having edge 3.2 each foot 3 is anchored in an opening 8 of the support plate 1. Each opening 8 has for this purpose a lower section 8.1 in FIG. 3 having a larger diameter and an upper section 8. 2 having a reduced diameter. In the illustrated embodiment, in this case the section 8.2 is formed in the two layers 4 and 5 and the section 8.1 in the two layers 6 and 7, wherein the difference in diameter of the opening portion 8.1 and 8.2 in the illustrated embodiment equal to or approximately equal to twice the wall thickness is, which has the respective foot 3 in the region of its upper end or edge 3.2.

Furthermore, the diameter of the opening portion 8.1 is equal to the diameter of the respective foot 3 has in the region of its upper edge 3.2, so that everyone in an opening 8 anchored foot 3 is taken with its upper edge portion in an opening section 8.1 and there with its upper edge 3.2 abuts against a formed by the transition between the opening sections 8.1 and 8.2 and the bottom of the layer 5 paragraph 9. Each foot 3 is further anchored in the corresponding opening 8 by gluing or other suitable means. Over the two upper layers 4 and 5, or via the paragraph 9 thus caused by the load of the load carrier 1 forces are transmitted to the foot 3, while the layers 6 and 7, although also to reinforce the support plate 2 in particular in the area serve between the feet 3, but essentially cause the lateral or radial securing of the feet 3.

Through the openings 8 and through the frustoconical design of the feet 3, the load carrier 1 with a variety of similar load carrier for transport and / or storage purposes stackable. For this purpose, the load carriers are stacked with their support plates 2 stacked in such a way that the feet 3 of each load carrier pass through the openings 8 of the underlying load carrier into the interior of one foot 3 of the underlying load carrier.

In the illustrated embodiment, the opening portion 8.1 is punched out in the lower layer 7 such that at the edge of this opening portion several successive, substantially triangular outer tabs 10 with flattened tips result, the (tabs) after insertion of the respective foot 3 in the associated Opening 8 bear against the outer surface of this foot and are glued to the foot 3 there. By the tabs 10 an additional anchoring of the feet 3 is achieved. Furthermore lie in stacked load carriers 1, the tabs 10 of the arranged in the corresponding stack on a load carrier further load carrier 1 with its free end 10.1 against the Tragplattenoberseite 2.2 of the underlying load carrier, and at one the local opening 8 enclosing edge region. The diameter of the opening section 8.2 for this purpose is at most equal to the diameter of the respective foot 3 in the plane of the free ends 10.1 of the flaps 10.

FIG. 4 shows, in a simplified illustration and in plan view, a reinforcing layer 11 made of a suitable flat material, for example a solid cardboard or kraft paper. In the region of each foot 3, such a reinforcing layer 11 is arranged between the layers 5 and 6, in such a way that it is glued to the adjacent layers 5 and 6. As particularly shown in FIG. 3, the reinforcing layer 11 has a thickness which is smaller than the thickness of the corrugated board layers 5 and 6.

In the middle of the reinforcing layer 10 is repeatedly cut with outgoing from a central point 12 incisions 13, in each case up to a point 12 concentrically enclosing imaginary circle 14, so that there are several, each substantially triangular inner flaps 15 through these incisions , The radius of the circular line 14 corresponds to half the inner diameter, the feet 3 have at its upper edge 3.2.

The individual, in the illustrated embodiment, square reinforcing layers 11 are provided in the region of the feet 3 such that each foot rests with its upper edge 3.2 in the region of the heel 9 against the reinforcing layer 11. The tabs 15 are applied against the inner surface of the respective foot 3 and secured there in a suitable manner, for example by gluing.

By the reinforcing layers 11, the anchoring of the feet 3 to the respective support plate 2 is substantially improved. In particular, the reinforcing layers 11 also effectively prevent the feet 3 from dodging inwards at their upper end, thereby losing or weakening the support of the support plate 2 on the respective foot 3. Although the reinforcing layers 11 consist of a relatively thin sheet material compared to the layers 4 - 7, an escape of the feet 3 is prevented at its upper edge 3.2 radially inwardly by the reinforcing layers 11 effectively.

It has been assumed above that a reinforcement layer 11 is provided in the region of each foot 3. Of course, it is also possible to provide such reinforcing layers only on such feet 3, which are subject to special stress or to use a continuous reinforcing layer, which then where feet 3 are provided, the inner flaps 15 formed by the incisions 13.

In particular, when using several, for each foot 3 separately provided reinforcing layers 11 is a production of the cargo carrier 1 in such a way possible that each foot 3 pre-assembled with its reinforcing layer 11 and then the feet 3 in the bottom layers 6 and 7 formed by the lower Part of the support plate 2 and in the local opening sections 8.1 are used, whereupon then after the bonding of radially projecting beyond the upper edge of the feet 3 reinforcing layers 11 with the layer 6, the further layers 4 and 5 are applied to complete the support plate 2.

As FIG. 3 further shows, the feet 3 are rolled radially inward at their lower end or at their lower edge 3.1, which results in an enlarged standing surface and a reinforcement of the feet at the lower foot end.

The feet 3 are preferably made of multiple layers of paper or cardboard, for example by winding, and gluing the individual layers with a suitable, especially moisture-resistant adhesive, so that the feet 3 Although also made of paper or cardboard, but an extremely large Have strength and sufficient resistance to moisture and liquid (including water).

FIG. 5 shows a further possible embodiment in a representation similar to FIG. In this embodiment, the feet 3a in the region of its lower end on the inside an additional ring 16, which is for example made in several layers by wrapping paper and / or cardboard (cardboard) or one or more layers of corrugated or solid board. In this embodiment forms the ring 16 a system 16.1 for the lower end of a foot 3a of a load carrier in a stack above it load carrier, so is realized by the rings 16 of the distance of the load carrier 1 and the support plates 2 of this load carrier.

The invention has been described above by means of an embodiment. It is understood that numerous changes and modifications are possible.

Above was further assumed that the tabs 10 are each formed from the material only the lower layer 7. It is understood that these tabs can also be formed from the material of several layers, for example, the layers 6 and 7.

Furthermore, it is possible to manufacture one or more layers of the support plate of a multi-corrugated cardboard or solid board.

Above, it was further assumed that a total of six feet are provided on the support plate. Of course, the number and arrangement of the feet 3 thereof may be different, wherein the arrangement is to be made in any case so that the load carrier is accessible by a lift truck. Especially with a load carrier in the size of a Euro pallet (1200 x 800 mm), a total of nine feet makes sense.

Above, it was further assumed that the feet 3 are made of solid board. Other materials, especially paperboard and paper materials are also conceivable for the feet, e.g. their manufacture from paper mache or from cardboard is conceivable.

It is expedient, furthermore, to round off the support plate 2 at the corners, as indicated in broken lines in FIG. 2 in FIG. 1, in order thereby to avoid tearing of a film (eg shrinking film) enclosing the packaging material and the support plate, at least at the edge.
