Description

The invention relates to furniture production and can be used in the manufacture of sofas, couches, beds, chairs and similar transformable products.,

Known spring furniture unit containing the upper and lower supports with flared, connected to one another by means of glasses and coaxially arranged in the glasses of the springs 1.

However, this spring furniture unit is inconvenient to use and unreliable in operation, because during operation of a known cushion, when compressing the springs, the walls of the bags are assembled into an accordion and fall between the spring branches, frayed and quickly deteriorated. In addition, spring noise occurs as they touch each other.

The purpose of the invention is to improve the usability and reliability of operation.

The goal is achieved by the fact that a spring furniture unit, containing upper and lower support with flanging, connected to each other by means of glasses and coaxially arranged in machine springs, has an additional support, made in the form of an elastic plate, having openings for glasses and placed between the upper and the lower supports, with each glass made of at least three telescopically connected parts, the two extreme of which are rigidly fixed respectively on the upper and lower supports, and intermediate p placed in the holes of the additional support.

FIG. 1 shows a spring furniture unit, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - additional support; in fig. 4 - block cell; in fig. 5 - cylinder engagement assembly.

The top support 1 has cups 2 with sockets 3 for accommodating springs 4. The cups 2 and sockets 3 are made in one piece with the support 1. The cups 2 have internal inclined flanges 5 at their ends 5. Bearing 1 has flanging at its corners 6. Cups 2 the sockets 3 are interconnected by radial ridges 7. All this together is an upper support in the form of a grid.

The bottom support 8 has cups 9 with sockets 10 for accommodating the lower bases of the springs 4. The cups 9 have outer inclined flanges 11 at their ends. The bottom support 8 has flanging 12 at its corners which form the corners of the block with flanging 6 of the upper bearing. Glasses 2 of the upper support are telescopically connected by means of intermediate glasses 13 with glasses 9 of the lower support 8.

At one end of the intermediate cups 13, outer flanges 14 are located, while at the other ends there are inclined inner flanges 15.

Intermediate cups 13 with their middle part are placed in an additional support 16, which is a grid-like plate with holes 17.

In the assembled unit, the springs 4 are compressed to a predetermined value and are kept in this state with the aid of glasses 2, 9 and 13 and supports 1 and 8. In this case, the upper support cups 2 and the lower support cups 9 are interconnected telescopically, limit the movement of the springs 4 in the plane of the supports, and isolate them from each other.

Flanging 6 and 12 provide the formation of the corners of the block.

To facilitate assembly, glasses 2, 9, and 13 can be made with slots arranged in their axial direction.

When assembling the block, the lower support 8 is placed with the glasses 9 upwards. In the sockets 10 are placed springs 4. An additional support 16 with fixed intermediate glasses 13 is provided with inner flanges 15 on the glasses 9. The upper support 1 is placed with the glasses 2 on the outer flanges 14 of the intermediate glasses 13. In this position, the upper support 1 is loaded over the entire surface up to as long as the flanges of the 5 glasses 2 engage with the outer flanges 14 of the glasses 13, and the inner flanges 15 of the intermediate glasses 13 engage with the external flanges of the 11 glasses. After that, remove the load from the support I. The springs 4 due to the elastic forces lift the support 1 to the upper position until flanges 5, 14, 15 and 11 approach each other.

The unit works as follows.

When the load is applied to the support over the entire surface or to a separate cell, the lower support 8 remains stationary and the upper support 1 moves downward, compressing the spring 4. The upper support 1 moves until the upper outer flange 14, the intermediate cup 13 approaches the upper support 1, and lower inner flange 15 - to the bottom support. In this position, the springs are as tight as possible and do not touch adjacent turns of each other. Thus, the spring noise is eliminated by avoiding the contact of the spring coils, and the springs are protected from overload. When the load is removed from the support 1, the spring 4 moves the upper support 1 to the initial position, and the springs 4 remain in the preloaded state due to the engagement of the flanges 14 and 15, intermediate 311341794
