The invention relates to a stackable shelf according to the preamble of claim 1.

Stackable shelves are widely used in department stores, wholesalers, and warehouses Storage of goods used. They are on site by the user, for example by department stores

J5 and place composed.

From DE-PS 24 29 122 is a stackable shelf specified type known. In this case, the shelf inserts as well as the support columns are made of stiff foldable ones Cardboard. The edges of the shelf inserts, which are bent upwards by 90 degrees at the bending edges, are through Slipping over the correspondingly folded support columns held together in the form of spacer supports.

Such a shelf is cheap to manufacture, but not stable for a number of applications enough. When assembling the generally inexperienced staff has major problems. That This stackable shelf can only be filled with goods after it has been assembled. The shelf inserts themselves cannot be used independently of the stackable shelf, as the upturned edges are exclusively are held in place by the support columns.

There are also known stackable shelves made of plastic. Such a shelf on the market consists, for example, of a square, stable plastic tub with four circular, cylindrical ones Recesses at the corners. In these corners become plastic pipe flush and with the help of a hammer fitted to stack several shelves on top of each other.

The plastic used is very expensive. The shelve

so has no so-called secondary benefit, i.e. H. it is not possible, for example, the shelf inserts in front of the Shipping, for the transport of the goods home, for the storage of the purchased goods or even to use other goods at home. The assembly is very tedious and requires a hammer; included parts can also shatter if the tolerance limits are not precisely adhered to. A dismantling is only possible with the use of force. If a different shelf size is to be created, this is often only expensive Tools possible.

Another well-known shelf with a round shelf insert is also made entirely of plastic. Are there the shelf inserts are connected with I-shaped columns. The connection is made via connecting pieces and locking projections. This shelf is even more complex to manufacture and has the same disadvantages as the previously described stackable shelf.

These shelves also indicate those with the use

disadvantages associated with plastic. They are relatively expensive and unusable when they are their elimination is time-consuming.

The invention is based on the task of a to design stackable shelf of the type described above so that it threaders while receiving and cheaper Manufacturing and handling is more versatile and more stable than the known.

The object is achieved according to the invention by the features of the characterizing part of claim 1.

Refinements of the invention are presented in the subclaims.

It is then provided that the corner edges of the edges have reinforcements arranged on the inside, which come into engagement with projections on the free edges of the inner legs. This will make the Strength of the connection between shelf inserts and support columns increases without affecting the ease of detachment suffer from.

The support columns preferably have a round cross section and are designed in the form of tubes. this enables a particularly cheap manufacturing process, both with a choice of material as cardboard Even with the preferred material for the columns, plastic (higher stability and strength).

The tips or free ends of the coupling pieces can expediently be conical and Have longitudinal ribs. In this way, a light, yet strong connection is guaranteed, which is also can be solved relatively easily again.

As a foot part, an intermediate column attached to a coupling piece, which is expediently is slightly shortened, with a ground socket οόεΓ role to serve.

As in the closest prior art, the material used for the shelf inserts is above all rigid Cardboard, preferably between 1–4 mm thick, is used. Such cardboard is sufficiently stable, light and especially very cheap. In addition, it is also environmentally friendly as it rots easily. In the Production is also not dependent on the scarce petroleum, as is the case with the use of plastic. This cardboard can be pasted, laminated or painted with thin paper. You can already be in this Stage, i.e. before the production of shelf inserts, can be provided with any imprint, in particular with Advertising imprints, or with different decorations, related to the sold goods, for the respective season or to match the shape of the shelf insert.

In addition, the shape of the edge formation, for example any folds or corrugations of the upturned edge, a special effect can be achieved.

The production of a shelf insert from cardboard is expediently done by punching out a large, flat cardboard box, a subsequent incision on the bending edges and a bending open the same.

The reinforcement on the inside of the edge ends can also be done by scratching the still flat cardboard of the shelf insert and bending the bending edges by 180 Cirad, followed by gluing to the inside of the edge ends. In this way, from the same material in an extremely simple manner, the reinforcement manufactured μ is to be at least at Regal inserts with rectangular or acute edges very purpose-to be especially advantageous has proven to be the parts of the support columns, although expensive something from the , but also to manufacture more stable plastic, which together with a shelf insert made of stiff, smooth cardboard with a thickness of 1-4 mm enables very stable, but cheap, stackable shelves. A thermoplastic such as impact-resistant polystyrene has proven to be the best plastic.

Cardboard or a cylindrically wound cardboard tube can also be used for the corner part and the intermediate column can be used.

The best conditions, especially from a static point of view, result when the shelf inserts are square, preferably have a square shape.

To increase the supporting surface of the shelf insert on the corner part, you can between the Provide intermediate plates for the inner legs of the holding parts.

According to part of the proposed solution to the problem, the support column consists of an intermediate column, Coupling pieces and a corner part with holding parts. These parts can be easily put together and can also be easily * dismantled again, for example to make a new arrangement or to replace the shelves, sell the goods with the shelves or store empty shelves. If you take the Corner parts away from the rain inserts, so they can be folded out to form flat pieces of cardboard. This results in an extremely low volume requirement for storing shelf inserts that are not required. The corner pieces can be stored independently. Of course, this benefit works in storage not only when dismantling, but also when storing the finished shelves in the Company, when shipping and storing the shelves that are not yet required in the department store, etc.

A particular advantage of the proposed solution is that the corner parts - detached from the Support columns - can remain on the shelf inserts and are therefore independent of their use can be used in a shelf structure. For example, it is possible to have these units in the factory to be filled with goods and sent to department stores or end users. It is still possible to do this To fill units in the department stores with goods and only then combine them with the support columns to form shelves put together. In addition, it is also possible for the buyer to use these units to transport the goods To take home with them, after the goods have been used up, the buyer can use these units for shelf use plus The corner parts can also be used as a container for any other goods.

An embodiment of the invention is shown in the drawing. It shows

Fi g. 1 is a plan view of a piece of flat cardboard as Raw material for a shelf insert,

Fig. 2 a corner part,

F i g. 3 shows a detail of the corner formation from FIG. 1,

4 shows a corner part according to another embodiment

Fig. 5 shows an arrangement of the intermediate column, coupling piece and foot part and

Fi ¹ J. 6 in a schematic representation of the arrangement of two stacked shelf inserts with intermediate columns.

In Fig. 1, the starting cardboard is flat, shown in a square shape. The corner pieces 2 are still included. Conveniently, the

visible outer edges, the corner pieces 2 and the recesses 27 for the inner legs 18, 19 of Holding parts 13 of the corner parts 5 (FIG. 3) and 23 (FIG. 5) are produced in a single punching process. In Fig. 1 are Furthermore, bending edges 3 are shown, about which edges 8 can be bent upwards by 90 degrees. Furthermore, bending lines 25 are shown, about which reinforcement parts 9 rotated 180 degrees and with the Inside of the corner edges 6, 7 of the edges 8 are glued. Two adjacent corner edges of the Edges 8 are denoted by 6 and 7. To enable bending around the mentioned bending lines 3 and 25, the outside is expediently scored, provided with a groove or in another suitable manner processed.

F i g. 2 shows a corner part 5. Inside are the inner legs with 18, the outer legs with 18 '. At the ends of the inner legs 18 are outward directed projections 10 can be seen. These projections 10 act with the reinforcements 9 mentioned above of the shelf insert together to form a stable, but easily detachable connection. Such a thing There is always cooperation between reinforcement 9 and projections 10 (or projections 11 in FIG. 4) then required if on a tight fit or an elevation between corner part 5 or 23 and the associated edge ends 6.7 of the edges 8 should be omitted.

A releasable connection also requires the provision of base plates 14 and intermediate plates 15, which preferably consist of a single common plate (in the embodiment of FIG. 5 Plates 16 and 17) ahead. The base plates hold the shelf inserts 1 firmly in their position. the end the F i g. 2 it can also be seen that the outer legs opposite the inner legs 18 18 'are not as long as this one. This helps save material and somewhat facilitates the handling of the Corner parts 5 and 23.

In Fig. 3 details of the corners of Fig. 1 are in shown on a larger scale. The edges 8, the corner edges 6 and 7 of these edges 8 and the To recognize reinforcement parts 9 to be bent. The shape of the recess 27 for the inner legs 18 or 19 of the corner parts 5 and 23 with holding parts 13 can be seen. To the bending edges 25 are the Reinforcements 9 bent up by 180 degrees. The arrows are intended to illustrate this bending. For the edges 8 bending lines 3 are shown.

F i g. 4 shows a corner piece 23 in cross-section, which is associated with Corner edges 6 and 7 of two adjacent edges 8 is in loose, removable engagement. The corner part 23 has attached to a circular sleeve and perpendicular

ίο mutually standing holding parts 13 on. These holding parts 13 consist of an incomplete U-shaped leg with a shorter outer leg 19 'and an inner leg 19 which has an outwardly directed projection 11. The U-shaped Legs are provided with base plates 16. There is an intermediate plate between the two U-shaped legs 17 is provided, which is formed in one piece with the base plates 16.

Fi g. 5 shows the structure of a three-part support column, namely for the special case of the lower end of the stackable shelf with a foot part. This in F i g. 4, the corner part 23 shown in detail is shown in FIG. 5 shown only hinted at. In this corner part 23 is a coupling piece 22 is inserted, which has a wider diameter in the middle, which acts as a stop for the corner part 23 and for an intermediate column 21. The tips 24 of this coupling piece are tapered. In this way, the coupling pieces can be very easily connected to the intermediate columns 21 or the corner parts 23 can be connected. In Fig. 5, the coupling parts also have longitudinal ribs. These serve also a better fit with easy assembly. In the lower end of a shortened intermediate column 21 'is a foot part in the form of a conventional roller 25 is inserted. This way the stackable shelf is up easy to move. Instead of a roller 25 can of course also other ends, such as one Sleeve, slipped over it or a rubber stopper inserted.

F i g. 6 shows a front view of an erected shelf with two shelf inserts 1. between them Support columns 20 are arranged. The support columns 20 consist of intermediate columns 21, coupling pieces 22 and corner parts 23.
