The corrugated sheet, in fact, serves as a reinforcing element, solid stiffeners located under the upper wall, along its entire width and length.

Shelves made in accordance with the prototype have a relatively large metal consumption, as well as a relatively large thickness due to the presence of a corrugated sheet. When transporting packages of such shelves, they occupy a relatively large volume. Moreover, in the case of stress concentration on the side walls of the shelf, they do not sufficiently prevent deformation of the shelf, both in its working position and in the transport position when the shelves are transported in packages.

The shelf for light shelving is intended primarily for storing light objects on it and in this regard it is made of one thin metal sheet forming the upper wall 1 (Fig. 1), the longitudinal side walls 2 and 3, and the lateral transverse walls 4 and 5 The shelf has a box-shaped, open bottom, parallelepiped shape. The shelf in its main design is made with a stiffener (Fig. 7) attached to the upper wall 1, and the ends of this stiffener are connected to the lateral transverse walls 4 and 5. This shelf design does not exclude another shelf design, which is made without a stiffener wall 1 (Fig. 1, 3, 5). The design of the shelf without the stiffener of the upper wall 1 is predetermined by the small dimensions of the shelf and the increased thickness of its upper wall.

In each corner zone of the shelf between its lateral longitudinal and transverse walls, gaps 6 are formed (Fig. 3), selected within 2.5-3.0 mm between the edges of two adjacent lateral longitudinal and transverse walls. Each gap has a height equal to the height of the side wall. The clearances 6 are designed to accommodate the transverse walls of another shelf of the rack, when they are connected to each other for transportation to the places of assembly of the shelves at the consumers.

In the corner zones of the shelf, at the edges of one longitudinal wall 3 (Fig. 1) there are flanges 7, bent towards each other, in other corner zones of the shelf, at the edges of another longitudinal wall 2 there are flanges 8, bent towards each other. Each flanging is a bent end of the lateral longitudinal wall with an inflection line of the side wall forming a rectangular element, which is a continuation of the lateral longitudinal wall of the shelf. In each flanging, a hole 9 is made, compatible with the hole 10, which is made in an adjacent lateral transverse wall. Each flanging in the transport position is bent inside the shelf towards the lateral longitudinal wall from which it is made. The longitudinal side wall 2 has a longitudinal stiffener 11, and the longitudinal side wall 3 has a longitudinal stiffener 12. The transverse side walls 4 and 5 have the same transverse ribs 13 stiffness (Fig. 1, 2, 8). The stiffeners 11-13 of the lateral longitudinal and transverse walls are made along the length of the side walls, are located in different horizontal planes, and the stiffeners 11 and 12 are located above the stiffeners 13. Each stiffener of the side wall is 90 ° to its wall

The combined holes 9 and 10 of the lateral longitudinal and transverse walls are also compatible with the holes 17 of the rack rack 14 in the operating position of the shelf (Fig. 4). In this position of the shelf, in the combined holes 9, 10 and 17, there is a fastener 15 connecting one wall 16 of the rack 14 with two side walls of the shelf through one hole in the transverse wall and one hole in the flange 7 (or 8) of the longitudinal wall. Such a connection is possible in the position of preloading any flanging to the inner surface of the corresponding transverse wall.

The other wall 16 of the same rack 14 is connected by another fastening element 15 located in the hole 17 of the second wall 16 of the rack and in the hole 10, which is made at each end of the side longitudinal wall 2 and 3.

Each flange 7 and 8 in the pre-installation position is located at an oblique angle to the adjacent side wall (Fig. 3) with the possibility of bending it towards the adjacent lateral transverse wall in the working position of the shelf. In this position of the shelf, each flange 7 and 8 is lapped to the transverse side wall and pressed against it and the rack 14 by the fastener 15.

Each rack 14 in cross section has the shape of a corner having two walls 16 (Fig. 4), each of which is connected to the shelf by a fastener 15, and in each wall 16 of the rack 14 there are many vertically oriented holes 17.

In one embodiment, the shelf has at least one stiffener 18 (Fig. 7), made in the form of a box located under the upper wall 1. The stiffener 18, in particular, has a trapezoidal shape in cross section. The rib 18 is connected by welding to the wall 1 on the lower side of the wall 1. The rib 18 is located between the side walls of the shelf and its ends are welded to the ends of the stiffeners 13 of the lateral transverse walls 4 and 5 so that gaps are formed between the walls 4 and 5 and the ends of the rib 18 for the location in them of similar walls 4 and 5 of another shelf that is joined to the first shelf when a package of two shelves is formed from them.

A longitudinal and transverse arrangement of one stiffening rib 18 or several ribs is provided, depending on the dimensions of the shelf. The height of the stiffening ribs 18 is selected less than the height of each side wall of the shelf, and the lower outer part of the ribs has a flat shape. The design of the shelf with a stiffener 18 of the upper wall 1 is predetermined by the relatively large dimensions of the shelf and the reduced thickness of its upper wall.

Between each transverse wall 4, 5 (Fig. 7) and the end face 19 of the stiffening rib 18 of the upper wall 1, a gap 20 is formed for arranging the same transverse wall of the other shelf in it when stacking the shelves.

The stiffener 18 has a dual purpose, the first of which is to increase the shelf resistance to bending and reduce its deformation during operation. Another purpose of the ribs 18 is to limit the mutual movement of a pair of shelves when they are connected to each other during the packaging process for compact delivery to the consumer. The specified restriction of movement is achieved by abutting the ribs 18 of one shelf (Fig. 9) in the rib 18 of another shelf when they are connected in a package consisting of two shelves. After such a connection of the two shelves, their upper walls 1 acquire additional rigidity, which reduces the possibility of deformation of the shelves during transportation, including loading and unloading, in which large shock loads are possible.

The manufacture of this shelf is carried out by cutting one blank from a sheet of metal and its flexible in different planes. When bending the billet, the upper wall 1 of the shelf is obtained, as well as the longitudinal side walls 2 and 3, the lateral longitudinal walls being made with flanges 7, 8 and stiffeners 11 and 12 (Fig. 7). The lateral transverse walls 4 and 5 are made with reinforced stiffeners 13 (Fig. 8) to increase the stiffness of the shelf in its transverse direction. For this, additional bends of the workpiece are performed so that the transverse walls 4 and 5, as well as their stiffeners 13, have two layers of the workpiece sheet (Fig. 8). In this case, flat forms of walls 4 and 5 are formed, which allow their planes to freely enter the gaps of another shelf when stacking a pair of shelves.

In the manufacture of lateral transverse walls 4 and 5, the ends of the workpiece are first bent by 180 °, the curved ends are laid on the workpiece and compressed, and then the ends of the workpiece obtained from two branches of the same workpiece are bent at right angles to opposite sides to the middle of the workpiece. In this case, reinforced stiffening ribs 13 are obtained as shown in FIG. 8. Such a manufacture of the shelf reduces metal waste during its cutting, energy and labor costs for the formation of the longitudinal side and transverse walls of the shelf associated with the need to connect the side walls to each other during the manufacturing process of the shelf.

The shelf works as follows. After the shelves are made, they are packaged in pairs as shown in FIG. 9. When stacking shelves, insert one shelf into another shelf in such a position that the transverse side walls 4 and 5 of one shelf (Fig. 8) are located in the corner grooves 6 (Fig. 3) of the other shelf, while the two shelves occupy the positions shown in FIG. 9. When one shelf is inserted into another shelf, they are displaced relative to each other in the horizontal plane, as shown in FIG. 9. In this position, one shelf easily enters another shelf until the ribs 18 of both shelves touch each other with their flat surfaces, or they touch the gasket 21, which is located between the flat surfaces of the ribs 18. With this position of the ribs 18, the pair of stacked shelves moves relative to each other, the edges 22 (Fig. 7) of the side walls 4 and 5 do not touch the end edges of the gaps 6 and the edges of the ends of the gaps and the paint layer are not damaged.

Shelves assembled in pairs are also packaged, for which at least one next pair of shelves (not shown), similarly assembled, is laid on a connected pair of shelves, wrapped in two pairs of shelves (or three pairs of shelves) with packaging material and, as such, the package of shelves is delivered to the place installation of shelving at the consumer. It should be noted that the shelves assembled in the bag turn out to be sealed in the bag and the upper wall 1 of each shelf is pressed against the upper walls of the shelves adjacent to the bag. When impacts are exerted on the package of shelves, their upper walls are more protected from deformation.

At the installation site, each shelf is removed from the bundle, flanges 7 and 8 are bent to the design working position so that a right angle is formed between each flanging and the longitudinal wall. Next, combine the hole 9 of each flanging with the hole 10 of the transverse wall, and combine these holes with the hole 17 in the wall 16 of the rack 14 of the rack. Fixing element 15 (Fig. 4) is introduced into the combined holes, by which a flange 7 or 8 is connected to the transverse wall of the shelf adjacent to it, connecting the lateral longitudinal and transverse walls of the shelf to each other via the wall 16 of the rack 14. Other parts are connected in a similar way shelves with corresponding walls of racks 14 of the rack. If necessary, in this way, other shelves located on the racks in a tier are connected to the racks of the rack. After connecting the shelf to the racks, one shelf or several shelves together with the racks form a rigid structure, as a result, the shelf under load works as a unit with the racks, while the longitudinal and transverse bending forces are distributed evenly throughout the shelf. In operation, the load from the walls of the shelf is transmitted through the fasteners to the racks 14, while the load is also perceived by the stiffener 18 and is more evenly distributed over the entire power circuit of the shelf. During the operation of the shelf and during its transportation, the stiffener 18 of the upper wall prevents deformation of the upper wall within specified limits, since the upper wall is made of thin metal sheet in order to reduce the metal consumption of the shelf and is designed for the corresponding loads.

Due to the described design of the shelf, in particular, the flanges of the longitudinal side walls of the shelf bent inward, the gaps between the walls in the corner zones of the shelf and the gap between the transverse wall and each end of the stiffener of the upper wall, allowing the transverse walls of the other shelf to be placed in the gaps, the use of the stiffener of the upper wall as a reinforcing element and limiter when stacking shelves, as well as due to other design features of the shelf, the possibility of compact and rational ansportirovki shelves for shelving installation places, and also possible to increase the bearing capacity of the shelf and receiving said technical result - reducing the concentration of deforming stresses on the shelf in its operating position and package transport.
