Description

The invention relates to a Faltregalsystem and a method for setting up the Faltregalsystems, and a method for producing the Faltregalsystems.

Shelving systems with at least one plug-in bottom are known, wherein the plug-in bottom has insertion elements for insertion into corresponding insertion openings of a shelf support. These have z. B. shelf support, which have parallel to the ground a "U-shaped" cross-section. The legs and the base surface of the "U" consist, for example, each of several superposed layers of corrugated cardboard, the base surface and legs z. B. are glued together in the region of the transition edges. The insertion openings have a plurality of layers of corrugated cardboard, wherein the lowermost layer is folded in the region of the leading edge, so that the former projecting region forms the front edge of the Einsteckbodens and is held by gluing to the leading edges of the top corrugated cardboard layers in a right angle folded position. As plug-in elements are glued to the lower side edges of the Einsteckböden, downwardly directed rigid angle elements which engage in corresponding slots of the legs of the "U-shaped" shelf support. Such shelving systems according to the prior art have the disadvantage that the production of the Einsteckböden is very expensive. Due to different material requirements - for example, to achieve a rigidity of the angle elements at the lowest possible cost of the plug-in floor - several materials are required in a single plug-in floor. With the large number of components used, the number of different materials installed in the shelving system increases, so that a high effort is required for environmentally friendly disposal of such shelving systems. In addition, the introduction of the angle pieces in the openings of the shelf support is expensive. If the highest number of individual components does not meet the highest dimensional accuracy requirements (eg when bonding the angle elements), there is also an instability or an insufficiently firm state of the shelving system or of the goods contained therein.

The DE 198 60 305 A1 shows a shelf system with at least one Einsteckboden, wherein the Einsteckboden has insertion elements for insertion into corresponding openings of a shelf support. The male members are designed as tabs, wherein the tab attachment is hingedly connected via a first bending edge with the base of the Einsteckbodens and the tab has a second bending edge for bending the tab end to be introduced into an opening. The design of the male elements as fold-out flexible tabs leads to a stability-reducing flexibility of attachment of the plug-in floors. Furthermore, there is a risk of tearing off the tab elements on the tab attachment when used several times.

The present invention is therefore based on the object to provide a simple to be built shelving system with high stability and low-wear plug-in elements.

This object is achieved by a folding shelving system according to claim 1, a manufacturing method according to claim 13 and a positioning method according to claim 14.

The proposed insertion with insertion on lateral or rear lower edges of the Einsteckböden and corresponding punched tab sections on the side walls allows a good and low-wear fixation by inserting the Einsteckböden in the corresponding punched tab sections on the side walls and the rear wall. The plug-in floors are thus fixed both on the side surfaces and on the rear wall and there are no aufklappenden flexible tab elements needed. This leads to an improved stability and fixation of the plug-in floors.

In addition, the Faltregalsystem can be set up very easily, since the punched tab sections must be introduced only in the existing insertion openings on the lower edges of the Einsteckböden without having previously unfolded on the Einsteckboden flexible tabs and bent.

Furthermore, the proposed insertion mechanism leads to a simplified production, since only openings at lower edges of the Einsteckböden and tab portions must be punched out at corresponding locations of the side walls and the rear wall.

The entire Faltregalsystem can z. B. be made of corrugated board material, so that the disposal of the Faltregalsystems is unproblematic and even a simple recyclability is given.

An advantageous development provides that the punched tab sections of the side walls and the rear wall have at their end connected to the corresponding wall two parallel crease lines and at its free end a recess, so that the free end of the tab sections can be taken and the tab sections by two times Folds along the fold lines are issued in the direction of the corresponding insertion of the Einsteckbodens can. As a result, the insertion of the tab sections into the insertion openings of the plug-in floor can be simplified.

The insertion openings are preferably slot-shaped and extend along the lateral or rear lower edges. According to a specific embodiment, two insertion openings are arranged on the rear lower edge and one insertion opening on the lateral lower edges.

The tab sections on the side walls and on the rear wall can preferably be punched out substantially U-shaped.

Further, preferably, an attachment for placement as a top plate on the foldable Aufstellrahmen be provided so that an information or advertising space is provided.

To support the Einsteckböden may preferably be provided for insertion between superposed Einsteckböden at least one support element.

Preferably, the Faltregalsystem is made exclusively of corrugated cardboard.

The side walls may preferably be double-layered, wherein the side walls have an inner wall facing the at least one foldable plug-in bottom and an outer wall. In this case, only the inner wall can have the punched tab sections. Further, the lower end of the inner wall may be shorter than the lower end of the outer wall by the thickness of a base part. The two-ply sidewalls may be integrally formed, and the inner and outer walls may be formed by folding the one-piece sidewalls.

Preferably, the Einsteckboden may be formed for folding up wall portions along the rear and side lower edges.

Advantageous developments of the present invention are specified in the dependent claims.
