Description

The invention relates to a method for the production of collapsible metal cabinets for storing clothes in industrial, educational, sports and other premises.

Known sectional cabinet for domestic industrial premises and the method of its assembly (ed. St. RU No. 217614, Bull. No. 16 from 05/05/68, IPC A47B). This cabinet contains a bottom, walls and a ceiling, screw legs and a shelf. The bottom, walls and ceiling have flanged stiffeners around the perimeter - flanges that serve for fastening by means of hollow caps.

The disadvantage of this cabinet is the complex and time-consuming technology of its assembly from the connection of cabinet parts using pistons.

Signs of an analogue that coincide with the features of the invention: bottom, walls, ceiling and shelf. The bottom, walls and ceiling, which have flanged stiffeners around the perimeter.

Known cabinet SHRN-22 600 and the method of assembly adopted for the prototype of the invention (website www.cerera-mebel.ru April 1, 2010) All cabinet parts are made of sheet metal that have flanged stiffeners at right angles. The cabinet is made in the form of a rectangular parallelepiped and contains a left 1 and a right 2 side walls, a rear wall 3, a door 4, a ceiling 5, a bottom 6, a shelf 7 and a channel (Fig. 10).

When assembling the cabinet, its connected parts are fastened with screws inserted into the coaxial holes, which are made in flanged stiffeners of the cabinet parts.

The method of assembly of the prototype cabinet:

1. We attach a ceiling 5 and a bottom 6 to the left wall 1 so that the holes in the parts to be joined become coaxial, insert screws into them and tighten to failure.

2. To the ceiling 5 and the bottom 6, mounted on the left wall, on the opposite side apply the right wall 2 so that the holes in the connected parts become coaxial, insert screws into them and tighten the nuts to failure.

3. In front of the bottom of the cabinet, insert the channel so that the holes in the parts to be joined become coaxial, insert screws in them and tighten the nuts to failure.

4. On the back side of the cabinet, between the left and right walls, insert the back wall with 3 flanged stiffeners inside the cabinet so that the holes in the connected parts become coaxial, insert screws in them and tighten the nuts to failure.

5. On the side walls of the cabinet, a rectangular bracket is reinforced under the shelf 7. The shelf is inserted so that the single flanged stiffeners enter between the bracket and the wall.

6. On the door 4 with the help of a self-tapping screw from below fix the axis of the door hinge. Then, the door is inserted into the channel with the lower axis, after which the holes on the upper flanged stiffener of the door are combined and the hinge axis is inserted into the ceiling in them and, using a self-tapping screw, fix it on the door.

The disadvantage of the prototype is the complex and time-consuming technology of assembly and connection of parts using screws, in addition, the assembly of the cabinet requires two workers and at least 12 minutes of working time.

Common features of the prototype and the invention are its parts fastened in the shape of a rectangular parallelepiped: left 1 and right 2 side walls, rear wall 3, door 4, ceiling 5, bottom 6 and flanged edges of all parts.

The technical result of the invention is to improve the manufacturing technology of the cabinet parts and the method of its assembly and reduce the complexity by using latches between the cabinet parts to be connected and four rectangular brackets with a cross-section of the channel, which allow the cabinet to be assembled without fasteners as a child’s designer for one worker in 3-4 minutes .

The invention is illustrated by drawings.

All cabinet parts, with the exception of door hinge rods, are made of sheet metal with a thickness of at least 0.4 and not more than 1.2 mm, for example, from steel of the St3 type.

The door hinge rods are, for example, made of polyamide.

The technical result of the invention is achieved due to the fact that the cabinet contains a left 1 and a right 2 side walls, a rear wall 3, a door 4, a ceiling 5, a bottom 6, four rectangular brackets 8, a tongue 9 of a latch or a groove 11 of a latch in one of the connected parts and protrusion 10 of the latch (figure 1 ÷ 9).

The latch is designed for fixed connection of cabinet parts in two versions of the connection of its parts. The latch contains a tongue 9 (Fig. 6) with a hole (used in the first embodiment of the cabinet parts connection) or a groove 11 (Fig. 7) made in one of the coupled parts (used in the second embodiment of the cabinet parts connection), and a protrusion 10 made in another part of the same pair (used in both versions of the connection of cabinet parts).

The tongue 9 is performed on one part of the pair of parts to be joined, the protrusion 10 is performed on another part of the same pair (the first embodiment of the connection of cabinet parts).

The groove 11 is performed on one part of the pair of parts to be joined, the protrusion 10 is performed on another part of the same pair (the second variant of connecting the cabinet parts).

When the protrusion 10 enters the hole of the tongue 9 or in the groove 11, there is a fixed connection of a pair of parts, which is accompanied by a characteristic click (6, 7).

The side wall 1 (figure 2) has a rectangular shape, the height of which is several times 2-5 more than its width. The lateral edges of the side wall 1 have flanged stiffeners at a right angle. The lower corners of the stiffeners are cut at an acute angle, for example, 45 °.

On the side wall 1 (Fig. 2), on lines parallel to its upper edge, at least two pairs of tongues 9 (Fig. 6) are made with through holes, the tips up. The tabs are bent into the cabinet at an angle of 2-50 °.

One pair of reeds 9 is made at the upper edge of the wall 1, the second at the lower, if necessary, the third and fourth pairs are performed between the upper and lower edges of the side wall 1 (Fig. 1).

The left 1 and right 2 side walls have the same identical design.

The rear wall 3 (Fig.3) has a rectangular shape of its edge, has flanged stiffeners at right angles with the grooves of the latch.

The height of the rear wall 3 is equal to or less than the height of the side walls, and its width is equal to or less than 1.2 times the width of the rectangular bracket 8.

The doors 4 have a rectangular shape (figure 5). The height of the door is equal to the height of the side wall minus the sum of the thicknesses of the ceiling and the bottom. The lateral edges of the door 4 have flanged stiffeners at right angles in the form of the letter P lying on its side. In the right flanged edge with the help of self-tapping screws, the axis of the door hinges is fixed. In the middle part of the door, to increase its rigidity, vertical corrugations are made.

The ceiling 5 has a rectangular shape (figure 4). The longer side of the shelf is equal to 0.8-0.9 of the width of the side wall 1, and the short is equal to the width of the rectangular bracket 8. All edges of the ceiling 5 around the perimeter have flanged stiffeners at right angles. On one line below the midline of the flanges of the ceiling 5, at least two protrusions 11 are made in the form, for example, of triangles with an acute angle downward.

The protrusions are the internal part of the latch (Fig.6), with which the ceiling 5 is attached to another part of the latch, made in the form of reeds 9 with holes and located on the side walls 1 and 2, made on another connected part. When assembling the cabinet, the protrusions 10 of one part of a pair of connected parts enter the holes of the tongue 9, made on another part of the pair and thereby fixedly fix the shelf on the side walls 1 and 2.

The ceiling 5, the bottom 6 and the shelf 7 are made identically and are also attached.

The ceiling 5 is mounted on the side walls in the upper part of the cabinet, and the bottom 6 - on the side walls 1 and 2 in their lower parts using at least two protrusions 10 (on the ceiling and the bottom) and two tongues 9 (on the side walls) made on them .

The bracket 8 is made of a rectangular shape and consists of a cross-member and two horns, the cross-section of which is in the form of a channel, the horns of brackets at one end of the channel shelves are rigidly fixed to the ends of the channel shelves of the bracket cross (Fig. 8). In addition, the horns on the same shelves of channels have elastic flanging at right angles to the inside of the channel, on each of which a groove is made (Figs. 7, 8). Two brackets are attached at the bottom of the side walls and two at the top (figure 1). Pairs of protrusions made at the lower and upper ends of the side walls go into the grooves made on the flanges of the shelves of the channels of the horns, and snap into place, providing a fixed connection of the side walls and the brackets 8.

The method of assembly of the cabinet according to the invention

Two brackets 8 are attached to the lower edges of one side wall 1 so that each edge of the side wall fits into the slot of one of the hollow horns of one bracket until a characteristic click occurs, which means that the protrusions made on the wall fit into the grooves made on the flanges of the channel shelves horns, and their motionless connection occurred. The lower edges of the other side wall 2 are inserted in a similar manner into the other horns of two brackets 8.

A third bracket 8 is put on the upper rear edges of the two side walls with horns, which fastens the upper rear edges of the side walls.

From the side of the front edges of the side walls, the rear wall 3 of the cabinet is inserted inside so that its lower edge fits into the cavity of the cross-piece of the lower rear bracket 8. The upper edge of the rear wall is fixed on the upper rear bracket using grooves that are on the stiffening ribs of the rear wall (Fig. 9).

The upper edge of the rear wall is fixed from the inside by a ceiling 6, for which the protrusions of the ceiling made on its flanges are placed in the holes of the reeds made on the side walls 1 and 2, at their upper edges. The bottom 7 is inserted into the cabinet and fastened, also its protrusions are inserted into the holes of the reeds made on the side walls 1 and 2, at their lower edges.

After that, the upper front bracket is inserted with 8 horns into the sidewalls of the left and right not completely by 20-30 mm (do not click!). Then the door with the hinge rods fixed on it is inserted into the lower front bracket 8, and the hinge rod is combined with the hole on the upper bracket from the top, then the upper bracket is fully inserted with the horns into the sides, until it clicks, the lower hinge rod is inserted into the hole of the hinge on the lower bracket.

For example, a shelf 7 for hats is fixed on the side walls 1 and 2, for which the protrusions made on its flanges are inserted into the holes of the reeds made on the side walls, for example, at a distance of 150-500 mm from their upper edge of the side walls.
