Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a chair whose seat plate moves up and down.

[0002]

[Prior Art]

 In the conventional chair, since the seating board on which the person sits is raised about 40 cm above the floor surface, it is difficult for an elderly person, a person with leg disabilities, a person with low back pain to sit alone.

The reason for this is that in order to sit down on a chair, it is necessary to take a sleeping or sitting posture, or to take a middle-waist posture from a standing posture, which imposes a considerable burden on the waist and legs. .

[0004]

[Problems to be solved by the device]

 The present invention allows elderly people and persons with leg disabilities to sit on the floor and move to a seat plate close to the floor, and then raise the seat plate to comfortably sit alone. The present invention is to provide a seat-plate up-and-down moving chair that can be installed.

In addition, according to the present invention, a person with low back pain who has difficulty in taking a middle lumbar posture can easily move his or her waist alone by lowering the seat while keeping the standing posture and moving to the raised seat. It is intended to provide a chair that can be hung up and down.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the chair of the present invention, as shown in the drawings, has two pairs of vertical columns 20 installed upright on a base plate 10 which is almost at the same height as the floor 100, and each pair of the vertical columns 20. A pair of elbow rest plates 30 are fixed to the top of 20 and four holes 41 are formed in a seat plate 40 facing the base plate 10, and each of the holes 41 has a pair of vertical columns. 20 is inserted, a loose air bag 50 is inserted between the base plate 10 and the seat plate 40, and the air bag 50 is inflated and shrunk so that the seat plate 40 is almost flush with the floor surface. The vertical movement is possible from a height close to 100 to the height of the elbow rest plate 30.

[0007]

【Example】

 An embodiment of the present invention is shown in FIGS.

The chair of this example is fixed to the base plate 10 having substantially the same height as the floor 100, two pairs of vertical columns 20 standing on the base plate 10, and the tops of the vertical columns 20 of each pair. A seat with a backboard 90 in which a pair of elbow rests 30 and four pairs of vertical pillars 20 are fitted into the four holes 41 so that the elbow rests 30 can be moved from near the base 10 to between the elbow rests 30. It operates by inserting the plate 40, the striped air bag 50 inserted between the base plate 10 and the seat plate 40, and the switch 71 from the power source 70 into the air bag 50, and pressurizes air. When the seat plate 40 is lifted to a certain height or more, the pneumatic pump 60, which allows the air from the air bag 50 to be discharged by turning the cock 61, slides on the guide 82. The switch 81 that had been used is disengaged and the operation of the pneumatic pump 60 is stopped. And device 80.

It is needless to say that the seat plate 40, the back plate 90 and the elbow rest plate 30 can be provided with various cushion materials, covers or decorations.

[0010]

[Action]

 Therefore, if the switch 71 is pushed, the pneumatic pump 60 is operated to pressurize the air into the air bag 50 and the seat plate 40 continues to rise, and if the push of the switch 71 is stopped, the seat plate 40 is set to an arbitrary position. Stop climbing at height. When the seat plate 40 rises above a certain height, the operation of the pneumatic pump 60 is stopped by the micro switch device 80, the press-fitting of air into the air bladder 50 is stopped, and the rise of the seat plate 40 is stopped. The risk of excessive inflation of the air bladder 50 and excessive rise of the seat plate 40 is prevented.

Further, the seat plate 40 releases air from the air bag 50 by turning the cock 61, and descends to an arbitrary height.

[0012]

[Effect of the device]

 According to the present invention, an sick person or a person with leg disabilities can be moved to a lowered seat plate of a stool, and then the seat plate can be lifted to be seated by one person while sitting down. A person with a low back pain who is not able to take a middle waist posture can still stand up and move it to a raised seatboard, then lower it to any height and sit on a stool by himself. Also, since the seat plate has vertical columns fitted in the four holes, it does not roll sideways when moving vertically.

Furthermore, the product of the present invention has the advantages that it is easy to operate, safe and easy to handle, has a simple structure, and can be manufactured at a comparatively low cost.
