Description

The utility model relates to the field of furniture production, in particular, to products of upholstered furniture of transformable design and can be used in the manufacture of sofa beds.

Known means of transformation for upholstered furniture, containing the support mounted on the linen box, levers, fasteners to the seat of upholstered furniture and intermediate links (see DE 3135323, IPC 3 A47C 17/13, 07/14/1983).

This tool has low reliability and is inconvenient during operation.

The closest to the proposed utility model in terms of essential features is a transformation tool for upholstered furniture containing a support mounted on a linen box, a two-arm lever, platforms for attaching upholstered furniture to the back and seat, and intermediate links that can be rotated and moved in a vertical plane (see DE 9401854.5 U1, IPC 7 A47C 17/04, 04/28/1994).

The known means of transformation for upholstered furniture has low reliability and is not convenient during operation due to the presence of a large number of intermediate links.

The technical result when using the utility model is to increase the reliability and ease of use by eliminating a large number of intermediate links.

The specified technical result is achieved by the fact that the transformation tool for upholstered furniture, containing a support link for connection with the linen box of the base, at the first end of the support

the link has a rotary lever, the opposite end of the rotary lever is located on the axis connecting the pad for fastening to the back and seat of upholstered furniture, and the mechanism for moving the linen box, made in the form of a two-shouldered lever - forms mounted on the support link, supports for attaching to the sidewall of the base frame and an intermediate link located between the short arm of the two shoulders of the arm and the support, while the long shoulder of the two shoulders of the arm is mounted on the platform for attachment to the back.

In addition, levers, platforms for fastening upholstered furniture to the back and seat and an intermediate link are mounted with the possibility of rotation in a vertical plane; the intermediate link is located on the support with the possibility of removal.

The utility model is illustrated by drawings.

Figure 1 shows the means of transformation in position for sitting, General view;

figure 2 shows the means of transformation in the position for lying, General view.

The transformation tool for upholstered furniture contains a support link 1 for connecting with the linen drawer 2 of the base 3, a lever 4, a pad 5 for attaching to the backrest 6 of the upholstered furniture 7, a pad 8 for attaching to the seat 9 of the upholstered furniture 7 and a mechanism for moving the linen drawer made in in the form of a two-shouldered lever 10, support 11 for attachment to the sidewall 12 of the base frame 13 and the intermediate link 14. The support link 1 for connecting the linen box with the base contains an axis 15 and an axis 16.

The lever 4 is mounted on the axis 15 with the first end with the possibility of rotation in the vertical plane, and the two-arm lever 10 is mounted with the possibility of rotation in the vertical plane with the arms 16, having different lengths, arranged at an angle to each other with the formation -forms. The long arm of the lever 10 is fixed with

the ability to rotate in a vertical plane on the platform 5 for attachment to the back of upholstered furniture, and the short shoulder is connected to the intermediate link 14 located on the support 11 with the possibility of removal, which is rigidly fixed to the sidewall 12 of the base frame 14 of upholstered furniture. The fastening of the support 11 to the base frame 14 allows not only to exclude damage to the backrest 6 and seat 9, but also to increase the size of the berth.

The platform 5 for attaching to the back of upholstered furniture and the platform 8 for attaching to the seat of upholstered furniture are rotatably interconnected by an axis 17 on which the second end of the lever 4 is mounted. made in the form of a latch located with the possibility of interaction with the axis (not shown).

On the support 11, pins 18 are fixed to protect the sofa from overturning, the pins 18 are located on opposite, horizontal sides of the support.

The transformation tool for upholstered furniture is installed on both sides of the upholstered furniture.

The transformation tool for upholstered furniture has two positions: a lying position and a sitting position.

Means of transformation for upholstered furniture works as follows.

To transform the furniture into a lying position, which is in the sitting position, in which the seat 9 and backrest 6 are rigidly fixed relative to each other by the locking mechanism, the upholstered furniture seat 9 is raised to the top in a position close to vertical, the lever 4 moves the axis 17 connecting the back 6 and the seat 9 and the backrest 6 are horizontal. In this case, the lever 10 is rotated in the direction opposite to the rear wall

the base frame 14 and pushes the linen box 2 forward from the back wall, by moving the short arm of the lever 10 and the intermediate link 14, which move the backrest 6 and the seat 9 from the back wall, eliminating their damage. And the locking mechanism no longer fixes the backrest 6 and seat 9, which are in a lying position, thereby forming a sleeping place.

When folding, raise the seat 9 to a position close to vertical, while the locking mechanism rigidly fixes the seat 9 relative to the backrest 6, after fixing the seat 9 is lowered down, the backrest 6 is in the vertical position, the lever 4 and the lever 10 are moved to the original position. When this linen box 2 is moved back to the rear wall, until the seat 9 is completely on the linen box 2, and the means of transformation for upholstered furniture will take up a position for sitting.

If necessary, the process is repeated.
