Description

Alignable wire shelf for a shelf system in a warehouse

The invention relates to a lined up wire shelf for a shelf system of a warehouse with the features of the preamble of claim 1

If one looks at an entire shelf level in a shelf system of a warehouse, the compartment covering runs from an outer edge of a first shelf support to an outside edge of a last shelf support. Between the beginning and the end, the compartment covering runs in the respective axial dimension of the shelf support. In the case of a grating compartment covering, the corresponding start, middle and end grids must be manufactured and placed in the correct position.

Wire shelves can be used instead of gratings in shelving systems in warehouses, provided that no high point loads are required. Such shelving systems can be designed in particular as a cantilever system, which has the advantage that the shelf levels can be used consistently without disruptive shelf supports, which is particularly advantageous for accommodating long goods. Basically, all types of shelves have to be fastened in a cantilever system, which is time-consuming and costly. US20190031439A1 describes a shelving system with wire shelves. The shelving system is not designed as a cantilever system and therefore has additional shelf supports on the front. Adjacent wire shelves overlap in the area of a support. However, additional screw connections are required to secure the wire shelves on the supports.

The object of the invention is thus to enable a compartment covering with only one type of shelf, which at the same time is securely fixed on the shelf frame without Necessity of a screw connection.

This object is achieved by a stringable wire shelf with the characteristics of claim 1 paint.

The wire shelf according to the invention is a uniform grid type that can be used equally in the start, middle and end field egg nes shelf, which reduces the effort in Fierstellung, storage and assembly. The formation of the compartment covering in the form of a wire mesh offers, together with a reinforcement by web-shaped reinforcement profiles on the underside, a sufficiently high load.

A particular advantage of the invention is that a self-locking system is created from a plurality of wire shelves according to the invention, which are laid next to one another in a row, in which the individual wire shelves no longer have to be additionally attached.

The wire shelf according to the invention consists of a functional th wire mesh as a compartment covering, the wire mesh protruding on one side over the reinforcement profiles and forms a support area and is provided on the other side with a bevel that forms a connection area. A connecting rod running transversely to the longitudinal direction of the shelf is attached there. The reinforcement profiles each have a connection recess in the front end area, which is able to accommodate the connection rod of a neighboring shelf. In the case of light loads, it is sufficient if only two spaced-apart reinforcement profiles have a connection recess and the other reinforcement profiles are somewhat shorter. However, all reinforcement profiles are preferably designed to be of the same length.

A positive connection of adjacent wire shelves can be formed not only by a transverse connecting rod that engages in the end connection recesses on the reinforcement profiles, but also by other positive locking means, which are z. B. hook into each other. The connection area does not have to be positioned exactly perpendicular to the support area, but can also run at an angle so that it extends into a side pocket on the cantilever arm or away from the cantilever arm. It is only essential that the connection area lies below the support areas, so that a continuous support plane is formed on the upper edge of the wire shelves that is free of obstacles for objects placed on it.

The reinforcement profile can also receive a further notch on one side at the top edge, which is shaped to match the profile of the shelf support. As a result, the reinforcement profile can grip further to below a profile projection of the shelf carrier, which is in particular designed as an H, T or I profile. These profile cross-sections have, since their center web is vertically aligned, laterally open pockets and the connection areas of the wire shelves preferably extend into the pockets, so that the connections between adjacent wire shelves at least partially included in the pockets and sections of the shelf support over the horizontal Profilab are covered. This provides additional security against being lifted from below. The reinforcement profiles that support the lattice structure between adjacent shelf supports can be designed in different ways:

- In a simple embodiment, vertically aligned sheet metal strips are sufficient, on the upper edge of which the lattice structure is welded and which are preferably hen at one end with connection recesses for a handle in a connection element of the adjacent shelf support.

- A T-profile is preferably connected to the lattice structure with its short, horizontally aligned profile leg.

- In the case of an H or I profile, one of the short, horizontal profile legs to be aligned is also connected to the lattice structure, while the vertical profile section has the connection recess.

- In addition, reinforcement profiles with a U-shaped or V-shaped cross-section can also be used. These then have connection recesses at the same level in the two profile legs leading from top to bottom for engagement in a connection element of the adjacent shelf support. Both the open and the closed profile side can be connected to the lattice structure.

Different types of reinforcement profiles can also be provided, that is, not all of the reinforcement profiles connected to the lattice structure have to be identical.

Furthermore, in a preferred embodiment, an open mesh is formed in each of the rear corner areas, via which a form-fitting attachment to the vertical shelf supports takes place, so that the wire shelves can no longer be pulled off the cantilever arms, please include.

Training and assembly of the side-by-side wire shelves are explained in more detail hereafter with reference to the drawings. The figures show in detail: 1 shows a shelf with a wire shelf from above;

2 shows two adjacent shelves with two wire shelves shown in detail from the front;

Fig. 3, 4 each have an assembly step in the assembly of two wire shelves side by side and

5 shows a connection point on a cantilever arm in detail.

FIG. 1 shows a shelf of a shelf system 100 with a wire shelf 10 placed thereon. The shelf is formed by two cantilever arms 2 spaced from one another and arranged parallel to one another, which are attached to vertical shelf supports 1.

The basic structure of the wire shelf 10 is formed by a lattice structure of longitudinal and transverse bars 13, 14 connected to one another. Reinforcing profiles 11 are attached underneath. A protrusion of the longitudinal rods 13 on the left side forms a first support area 15 with which the wire shelf 10 rests directly on the top of the cantilever arm 2. On the right-hand side, the protrusion of the longitudinal rods 13 is even longer; These run over the entire width of the cantilever arm 2, where they form a second support area 16. On the right outer edge of the cantilever arm 2, the longitudinal bars 13 are angled downwards and form a connection area 17.

An open mesh 19 is formed in each of the two rear corner regions, that is to say that the cross bars 14 are interrupted there. The half of the rearmost support rod 13 can be brought behind the profile leg of the shelf support 1, so that the wire shelf 10 is positively secured against pulling forward and against moving to the side.

In the view of the shelves lying next to one another from the front in FIG. 2, the formation of the reinforcement profiles 11 can be seen in particular. These have a slot-shaped connection recess on the left end face 12. A notch 11.1 can be seen at the top edge so that the reinforcement profile 11 can be pushed under the horizontal, laterally protruding profile legs of the cantilever arm 2. The cantilever arm 2 is formed in the exemplary embodiment from an I-profile on which the side open pockets 3 are present, into which at least the respective end region of the reinforcement profiles 10 protrudes as soon as the connection between two adjacent wire shelves is established.

The vertical connection area 17 on the right cantilever arm 2 ends with a connection rod 18 which extends in the direction of the depth of the shelf compartment, thus transversely to the longitudinal rods 13.

To the right of this is a section of a further wire shelf 10. The connection recesses 12 in its reinforcement profiles 12 are located at the level of the connection rod 18.

To assemble a continuous shelf, a first wire shelf 10 is pushed in a slightly inclined position between the adjacent shelf supports 1, so that the open meshes 19 (see Fig. 1) arranged at the rear of the shelf shelf into the leg of the shelf support 1 on both sides when it is lowered can intervene. The first wire shelf 10 is thus secured in a form-fitting manner on adjacent cantilever arms 2, as shown on the left in FIG.

Another wire shelf 10 is then fed in from the right, like the one in an inclined position, as shown in FIG. The second wire shelf 10 rests with its support area 15 on the cantilever arm 2 as does the first wire shelf 10 with its support area 16. When lowering, the connection recesses 12 on the reinforcement profiles 11 of the second wire shelf 10 right into the connection rod 18 in the connection area 17 of the first Wire shelf 10 on the left, so that there is a form-fit connection in the finished position according to FIG. FIG. 5 shows in an enlarged section the connection point between the two wire shelves 10 with the position of the connection area 17 with the connection rod 18 and the connection recesses 12 on the neighboring wire shelf 10, in which the connection rod 18 engages. The reinforcement profiles 10 extend beyond the connection area 17 into the side pocket on the cantilever arm 2. For this purpose, they are somewhat reduced in height at their upper edge by a notch 11.1. The protruding area cannot be lifted upwards. As a result, the connection point is positively established and the interconnected wire shelf floors 19 are secured against lifting.

All subsequent wire shelves in the shelf are based on the same principle and each with a small depth offset from one another, so that the arrangements of the longitudinal rods 13 in the connection areas 15, 16 mesh with one another.

Without the need for separate fastenings, each of the wire shelves 10 is secured against pulling out forwards, against lateral Ver as well as against lifting positively on the shelf frame 1, without screws or other securing elements neces sary.
