BACKGROUND OF INVENTION
The present invention refers to the health care and prevention medical supplies manufacturing, in other words, to special devices for prevention and treatment of spinal diseases.
The problem of the spinal and especially lumbar diseases is one of the essential problems of the modern society, caused by the lack of physical loadings and so called hypodynamic lifestyle.
There are lots of curative and training types of devices, which are well known in the world. All of them are intended to load and strengthen different kinds of the user's muscles. For example, they include the devices described in the U.S. Pat. Nos. #6,824,505B1; 6,830,542B2; 6,827,676B2.
However, the devices mentioned above do not provide any therapeutic effects, which are necessary for prevention and treatment of spinal diseases.
The purpose of the present invention is to create a device, mostly affecting muscles and cords, located near and between the patient's vertebras, which help to prevent and treat various spinal diseases, especially the lumbar area of spine.
SUMMARY OF THE INVENTION
According to the present invention the chair refers to the health-improvement medicine, more precisely—to the special devices for spine diseases treatment and prevention.
Furthermore, the chair has additional advantages, in that:
- it provides the seat height regulation, which allows to adjust of said chair for people with different height, in the correct and comfortable position;
- it allows adjustment of the seat incline (swing amplitude), which provides the user with the a possibility to install the chair depending on the user's physical health.
- it also provides the possibility of a chair-folding to a portable position, which allows for the wider sphere of usage (places of home, of work or places of rest).

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1, 2 show one of the preferable embodiments of the offered invention. According to it; the chair includes a base (10), a seat (12) connected with said base, a device (14) for a turning of said seat in horizontal flatness and inclining in vertical flatness. In addition, the chair is equipped with a device (16) for seat height regulation and a device (18) for seat incline (swing amplitude) regulation.
According to this version (FIG. 1, 2) the base includes a ring (26) made, for example, of pipe billet or any other similar material. No less than three connections (28) are attached to the ring (26) in the form of pipes or bars, in equal distances from each other along the ring (26). Spare ends of the connections (28) are attached to a sleeve (30). Said sleeve has internal thread linked with a screw (24), which is connected with the seat (12) by a ball-and-socket join (14). A ball part (32) of this join (14) is attached to the screw (24) and is placed into a socket part (34). Said socket part is fixed to the back side of the seat (12). This kind of connection allows for turning the seat (12) in horizontal flatness and to incline it in a vertical flatness.
There is a regulator (16), to adjust the height of the seat (12) which includes the screw (24), the sleeve (30) and a check-nut (20).
The seat incline regulator (18) provides an adjustment (swing amplitude) of the seat (12) in vertical flatness. The regulator (18) includes a stopper-nut (18a), and a check-nut (22), which are joined with the screw (24). According to the present embodiment, shown on FIG. 1, 2 the chair works as follows:
in the beginning the ball-and socket join (14) is gripped with a help of the stopper-nut (18a) and the check-nut (22). Than the seat (12) together with the screw (24) is adjusted to the desired height, and this seat (12) position is fixed with a help of the check- nut (20). After that the seat (12) is installed at the requested incline (swing amplitude) by a twisting off the check-nut (22) and the stopper-nut (18a). After that the user sits down and performs the exercises.
FIG. 3, 4, 5 shows another preferable embodiment of the presented invention, which additionally provides portability of the offered chair. This advantage is supplied by a device (36) for over-turning the seat (12).
Said device includes a U-shape member (38) attached to the upper part of the base (10), a fixed axis (40) on which turning sleeve (30a) is placed and a stopper (42) for fixing the seat (12) in a working position.
The chair, according to this embodiment (FIG. 3, 4), works as follows: To unfold the chair (FIG. 4) into working position (FIG. 3), seat (12) together with all its connections (14, 24, and 30a),turns over by 180 degrees, and the working position of the chair is fixated by a stopper (42).
The further operations with said chair are performed as above described operations with the first embodiment of this invention.
The folding of the chair into the non-working position is carried out in the backward succession.
