Description

  The present invention relates to a chair that can be used for rehabilitation as well as being useful when used while standing or working in the kitchen or in a kitchen, etc., as well as assisting in the exercise of walking with standing weight. It is.

There are many workplaces that work while standing for a long time, and such workplaces have a heavy work load and tend to be disliked.
In addition, when cooking in a home kitchen or the like, it tends to get tired as time goes on, and is often painful especially for elderly people and those with weak legs.
Also, as part of walking training for rehabilitation etc., there is no auxiliary tool to move freely using both feet or one foot in a figure that is close to independence, so traditionally walking training held by handrails etc. Or use crutches.
However, there is a problem that walking training cannot be performed without the help of a caregiver or the like when the handrail is incapable of being held by a handrail or when crutches cannot be used.
Conventionally, chairs having the following contents are known as chairs developed for standing work.

Actually, Heihei No. 05-76365 said, “You can change your posture at any time by placing your hips in a standing position and putting your weight on your floor. Even if you put it in, the chair does not move and it will be supported stably, with the retractable caster device holding the saddle, there is no movement, it is a small workable chair for standing work, and the saddle surface of the saddle type cushion sitting on the crotch, Supporting the pelvis with a hemispherical projection cushion, the rotatable caster with a spring post, if the weight is heavy, the pedestal will land when the spring contracts about 10 mm, the caster will not work, the weight will move to the foot and the waist will float The caster works by pushing up the pedestal and can rotate and move while holding the saddle.

However, in the case of this chair, a caster is attached to a washer formed in a cross shape, and has a structure that improves stability in the same manner as a normal chair.
For this reason, it is stable when you leave your weight, but when you move while keeping your weight in the saddle, you need to walk with your feet, but at this time, the washer spreading in a cross shape In addition, there is a problem that the caster gets in the way when moving the foot back and forth, and is very difficult to move. In addition, since washers and casters obstruct the feet, they cannot be used for walking training. If the cross-shaped spread of the washer is reduced so as not to obstruct the movement of the foot, the stability is lost and it is dangerous.

  An object of the present invention is to provide a chair with a caster that is effective for walking training while keeping the weight in a standing position without any drawbacks as described above, performing work while moving as it is, and walking training.

  In order to achieve the above object, according to the first aspect of the present invention, in the movable chair for standing work and rehabilitation, one front wheel caster bar is made to face forward, and the rear wheel is perpendicular to the rear end of the caster bar. By connecting the caster bar, the leg seat configured in a T shape in plan view, the caster attached to the tip of each bar of the leg seat, and the front wheel caster bar are vertically raised from the middle. The vertical support pipe, the height adjustment rod with the lower end inserted into the inside from the upper end of the vertical support pipe, and the front wheel caster bar mounted on the height adjustment rod are attached in the forward direction. And a saddle.

  Furthermore, in the invention according to claim 2, in the movable chair for standing work and rehabilitation according to claim 1, the front wheel caster bar and the vertical support pipe are detachable, the vertical support pipe, the height adjusting rod and The saddle is also configured to be detachable so that it can be disassembled and transported and stored.

  The chair having the above-described structure is used for sitting or standing in a standing posture and keeping weight, and both feet are put on the floor to stabilize the posture and work or work. And when moving, it is possible to move in any direction and move freely by applying a little force to the foot. At this time, there is only one front wheel caster bar between the user's feet, and the rear wheel caster bar is on the rear, so that it does not interfere with the movement of the foot. For this reason, the front wheel caster bar needs to have a sufficient length.

The leg seat with a caster attached to the tip is T-shaped and has a single front wheel caster bar, so that both legs or one leg can be moved across it. Don't be.
As a result, it is not only easy to use, but is particularly effective when used for walking training during rehabilitation. At this time, even if the hand is crippled and the handrail or crutch cannot be used, the leg seat is T Because it is shaped like a letter, it is stable, and walking training can be performed safely on its own.
In addition, since the leg seat of the present invention has a T-shape, it can smoothly move in the straight direction and can easily change the direction.

  Below, the Example of this invention and its usage example are demonstrated in detail using FIGS. 1-4. In each figure, reference numeral 1 denotes a leg seat, and this leg seat 1 has one front wheel caster bar 2 facing forward, and a rear wheel caster bar 4 at a right angle at the rear end of the caster bar 2. By attaching, it is configured to exhibit a T-shape in plan view. A front wheel caster 3 and a rear wheel caster 5 are respectively attached to the tips of the bars 2 and 4 of the leg seat 1.

Reference numeral 6 denotes a vertical column pipe which is vertically raised from a substantially middle position of the front wheel caster bar 2 by a base shaft pipe 7. A height adjusting rod 9 is attached, and a saddle 11 is attached on the height adjusting rod 9 in a forward direction in accordance with the direction of the front wheel caster bar 2.
In the chair, the front wheel caster bar 2 and the vertical support pipe 6 are detachable by screws 8 at the base pipe 7, and the vertical support pipe 6 and the height adjustment rod 9 are attached / detached at the height adjustment knob 10. It is free. Moreover, the height adjusting rod 9 and the saddle 11 are detachably attached by a fixing screw 12.
