Description

The inventive utility model relates to household items, in particular, to furniture, including children’s, and is intended for games, sitting and resting lying for children of preschool and primary school age.

Currently, the industry produces a large number of sofas for children, but they differ from sofas for adults only in size and sometimes more vibrant upholstery. There are completely no rocking sofas that can be used not only for relaxation, but also for games.

Known rocking chair (SU, Patent No. 283939, publ. 10/06/1970), consisting of a base, a rack rigidly attached to it and a seat bearing a movable frame, consisting of two plates covering the rack, and equipped with rollers, while the lower roller of the frame placed in the vertical groove of the rack, and the upper - in the groove of the concave surface of the rack. The chair is comfortable to use, to stop swinging the frame is equipped with a seat position lock. However, this chair is designed to rest while sitting and cannot be used to rest lying down.

Known children's swings that can be transformed into a cradle for motion sickness for babies (RU, patent No. 2254046, publ. 06/20/2005). The swings include a horizontal crossbeam with attachment points for the suspension of seats for it and two racks pivotally mounted at each end of the crossbeam with their fixation unit together.

This design can be used both for games and for relaxation, but only for the smallest children.

The use of racks for attaching a swing makes the design very bulky and inconvenient when used at home.

Closest to the claimed technical solution is a sofa (RU, certificate for PM No. 7815, publ. 16.10.1998) containing a base, seat, back and armrests, the base being a support made in the form of a beam with two legs, and the seat is rigidly attached to the support, the back and armrests are fixed. This sofa is easy to manufacture. You can relax on it both sitting and lying. However, in this design, the seat is rigidly fixed to the base and, therefore, there is no swing function.

To obtain a technical result, which consists in expanding the functionality of the sofa, in increasing the convenience and comfort, in the sofa containing the base, a seat with a back and armrests, the base is made in the form of a bed, consisting of two racks connected by crossbars, on each rack a swing mechanism consisting of a movable support, two vertically directed levers and four rolling bearings is fixed, while two bearings are installed at the upper ends of the levers, and their axes are tovogo compound fixed on the rack, in turn, the other two bearing installed in the lower portion of the movable support, and their axis via bolt connections are secured at the lower ends of levers, wherein the seat is rigidly fixed on movable supports.

A variant is possible when the levers are installed at an angle to each other.

Figure 1 presents a General view of the base and seat of the sofa; figure 2 - sofa stand with a swing mechanism: a) a general view, b) a front view, c) a view without a movable support.

The sofa (figure 1) contains a seat 1 with a backrest 2 and armrests 3 fixed on it, as well as a base made in the form of a bed consisting of two racks 4 interconnected by crossbars 5, and a swing mechanism 6 is fixed on each rack 4.

The swing mechanism (figure 2) consists of a movable support 7, two vertically directed levers 8 and four rolling bearings 9.

Two bearings 9 are installed in the upper ends of the levers 8, and their axles 10 are bolted to the rack 4, in turn, two other bearings 9 are installed in the lower part of the movable support 7, and their axes are bolted to the lower ends of the levers 8.

Seat 1 with a back 2 and armrests 3 can be made in the form of soft elements and rigidly fixed to movable supports 7.

When rocking the seat 1, the levers 8 make pendulum movements, and the seat 1 is translationally rotational, while maintaining a horizontal position.

If the levers 8 are installed at an angle to each other, the seat 1 deviates from a horizontal plane in one direction or another when translationally rotating.

Rocking the couch can be carried out by both the seated person and another person. After the oscillation stops, the oscillations die out.

This design allows you to use the sofa as a sofa-rocking chair, as well as to increase the convenience and comfort when using it.
