RU233291U1 - Cover of a collapsible metal cabinet - Google Patents

Abstract

The utility model relates to the production of metal furniture. In order to reduce the metal consumption of the lid, it is made from one solid thin-walled sheet by bending it and obtaining the top wall, as well as the side, front and rear walls with flanges extending to the middle of the lid. The side, front and rear walls of the lid in their cross-section have an L-shaped profile, while in the front wall, top wall, as well as in the flanges of the front wall and in the flanges of the side walls, cutouts are made that form nests for removable connectors located and secured in them.

Description

The utility model relates to the production of metal furniture, in particular to the components of metal cabinets made from thin steel sheets.

Known are covers of collapsible metal cabinets made from a single solid sheet by bending it and obtaining a top wall, side, front and rear walls in the form of flanges extending at a right angle from the wall of the cover (RU 193986 U1, 20.11.2019. RU 134410 U1, 20.11.2013).

A known cover of a collapsible metal cabinet is made from a single sheet by bending it and obtaining a top wall, side, front and rear walls with flanges extending to the middle of the cover (RU 165411 U1, 20.10.2016 - prototype). As a result of using cabinets manufactured according to the said patent, the complexity of assembling the cabinets was established, as well as insufficient rigidity of the cabinets and their resistance to distortions that occur during the use of the cabinets. In this regard, the technical task of the said type of furniture is to impart increased rigidity and stability to the cabinet body and its components in the working position, provided that the design of the cabinet body excludes frame solutions, welded joints, as well as strengthening the cabinet frame by thickening the walls of the cabinet and its components made of steel sheets.

The technical result of the presented utility model is to increase the rigidity of the cover and reduce its metal consumption. An indirect result is to reduce the labor intensity of the cabinet assembly.

The technical result is obtained by the cover of a collapsible metal cabinet, made from one solid thin-walled sheet by bending it and obtaining an upper wall, as well as side, front and rear walls with flanges extending to the middle of the cover, wherein the side, front and rear walls of the cover in their cross-section have an L-shaped profile, while in the front wall, in the upper wall, as well as in the flanges of the front wall and in the flanges of the side walls, cutouts are made that form nests for removable connectors located and secured in them.

Fig. 7 shows the left corner of the cover with a connector installed in it, view from below.

The cover of the collapsible metal cabinet is made from one solid thin-walled sheet by bending it. The cover has a box-shaped form, which is formed by the top wall 1 (Fig. 1), side walls 2 and 3, front wall 4 and rear wall 5. The side walls, front and rear walls have wide horizontally oriented flanges 6 (Fig. 2, 3) at the bottom, which are ground parallel to the top wall 1 to the middle of the cover. Each flange 6 has an upwardly bent end 7, which forms the lower stiffening rib of the cover. As a result, each side wall, front and rear walls of the cover have an L-shaped profile of the same cross-section at the end.

A cutout 8 is made in the front wall 4 (Fig. 1). A cutout 9 is made in the top wall 1. A cutout 10 is made in the flange 6 of the front wall 4 at each end (Fig. 4). Cutouts 11 and 12 are made in the flanges 6 of the side walls 2 and 3, respectively. The said cutouts form sockets 13 and 14 for inserting removable corner connectors 15 and 16 into them, connecting the cover with the side walls of the cabinet.

The lid operates as follows. The lid is placed together with the connectors 15 and 16 fixed in it in a horizontal position, the protruding pins 17 of the connectors are inserted into the sockets of the side walls, which are made in the front parts of the side walls (not shown) and the pins of the connectors are connected with the side walls and the lid with the side walls of the cabinet, which are preliminarily installed in a vertical position, using screws. After this, the rear wall of the cabinet is attached to the resulting cabinet body. The screws are inserted into the holes 17 of the lid, which are located along the perimeter of the lid on its rear side and sides as shown in Figure 5. The connection of the lid with the side walls of the cabinet is simplified due to the use of connectors.

During the use of the cabinet, the main mass of the cabinet and its contents is transferred to the side walls and bottom of the cabinet, to the flanges of these elements. Dynamic loads from the cabinet swinging to the sides are perceived by the rear wall, cabinet joints, lid and bottom of the cabinet. Due to the form of the lid walls and the design of the joints described above, the strength of the cabinet parts in their connected position and the strength of the cabinet as a whole are significantly increased, while due to the increased strength of the joints, the thickness of the steel sheet from which the lid is made is reduced.

The reduction in the labor intensity of cabinet assembly is achieved by the fact that the simpler assembly of the cabinet is carried out by one assembler.
