Joint chair {JOINT CHAIR PROTECTION}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a chair for protecting a joint, and more particularly, to a joint protecting chair for assisting a standing of a user so that the buttocks of a user are inclined by a diagonal line so that the joint does not become unreasonable.

In general, a chair is a piece of furniture, consisting of a backrest seat and a supporting leg. Western style chairs have been made into various types of chairs, such as Vassilj, chalks, rocking chairs and sofas.

The chair is used for office or leisure, study, subway, bus, etc., and the seat and backrest supporting the hips are fixed to support part of the body.

Such a chair is useful in real life, but some users have a fuss of use. For example, a person sitting in a chair or having a discomfort in his / her lower limb joints may become uncomfortable when used.

With the recent development of medical technology and interest in health, the elderly population is increasing, and the development of appropriate facilities and household goods that can help the elderly to live more conveniently and safely in daily life is becoming more important. In the case of elderly people, it is difficult to control them by sitting on the floor or getting up or sitting on a chair or getting up on a chair when a lot of crowded joints such as a knee are frequently used. have.

In addition, even in the case of patients suffering from joint damage caused by accident, it is difficult to control the force even in the case of damage to the back or leg joints. If the force is not applied or the force is excessively applied, .

Accordingly, the present invention has been proposed in order to overcome such a problem, and it has a structure in which the upper and lower portions are changed by the angle of the seat which the hips touch, and when the weight of the person is put on the seat, And it is intended to provide a joint protecting chair which can be raised in a chair safely since the angle of the seat plate is changed again when the lever is pulled when the user wishes to take the opposite and gently pushes the user's buttocks.

According to an aspect of the present invention, there is provided a chair comprising: a base having a base for a chair and a coupling groove formed in a plate formed on the base to be spaced apart from the floor; A seat mounted on one side of the base with a hinge angle so as to be raised or lowered to cover the base and support the buttocks of the user; A rail engaged with the seat in an inner space formed by the seat and the base; A bar that slides along the rail within the rail; A pin formed on one side of the bar and protruding in a direction corresponding to the rail, the pin being insertable into the coupling groove and having a locking portion; A spring coupled to one side of the pin and coupled to the other end of the rail to shrink or relax to move the bar along the rail; And a lever which is hinged to the other side of the bar and protrudes from one side of the side plate and is pulled up by a user to lift up the side plate. When the lever is pulled, the side plate can be lifted to raise the user.

The joint protection chair may further include at least one seat spring fixed to the plate formed on the base so as to push the seat at all times.

Such a joint protection chair can be fixed by engaging the latch with the plate along the bar inserted by the pin into the coupling groove and being pushed by the expansion of the spring when the seat plate covers the base.

When the lever is pulled by the lever, the bar is pushed by the hinge in the direction of compression of the spring along the rail, and the latching portion of the pin is pulled out from the coupling groove, have.

According to such a joint protection chair, when the user sits, the seat plate is pressed by the hips, and the spring seat is used to seat the seat slowly. When the lever is pulled in the direction of the body when the seat is lifted, the seat plate is raised to raise the user . Therefore, it is possible to make standing up without imposing a physical burden.
