BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an upright assisting chair according to the present invention. FIG. 1 shows an upright assistance chair 1 according to the present invention.
This stand-up assisting chair 1 has ordinary front legs 2, rear legs 3, armrests 4 and backrests 5 in the form of a pipe.
The seat plate 6 is divided into two. Of the seat plate 6, the front seat plate 6a, that is, the side supporting the back of the knee, is fixed to the frame, and the rear seat plate 6b, that is, the backrest 5 side, is rotatably attached to the front leg 2 of the chair. It is configured to be supported up and down by the rotating frame 7.

The rotating frame 7 is a pipe frame having an L-shaped side surface, and is attached to the lower surface of the rear seat plate 6b, while a supporting pipe projecting from the rotating frame 7 is provided at an intermediate portion of the front leg 2. 8 so as to be freely rotatable. The distal end side of the rotating frame 7 is located near the base end side of the front leg 2, protrudes forward of the front leg 2, and has a footrest 9 attached to the distal end. A gas spring 10 is interposed between the rotating frame 7 and the front leg 2 as an extension biasing support means.

The footrests 9 are provided as a pair at the tip of the rotating frame 7, and when not in use, each of the footrests 9 is stored in an upright position along the front leg 2, while only when in use, the other footrests 9 are not in use. Are held in a horizontal state so as to face each other. The surface of the footrest 9, that is, the portion on which the user's foot rides, is formed in a convex shape so that the foot can be easily put on the footrest 9, and is provided with a plurality of grooves as slip stoppers.

The gas spring 10 includes a cylinder 11
And the rod 1 urged by the pressure of the gas sealed in the cylinder 11 so as to always extend from the cylinder 11.
2.

The upright assistance chair 1 according to the present invention is constructed as described above, and its function will be described below.
When the user depresses the footrest 9 and puts weight while holding the armrest 4 while sitting on the chair 1 (see FIG. 2), the rotating frame 7 becomes a support pipe attached to an intermediate portion of the front leg 2. 8 as a rotation axis, the gas spring 1
0, the footrest 9 comes into contact with the floor, while the rear seat plate 6b projects from the frame.
Looming. At this time, the gas spring 10 presses the rotating frame 7 with the rod 12 extending from the cylinder 11. Thereby, the user can take a posture of the middle waist state just before standing with the hand on the tip of the armrest 4, and can stand up easily (see FIG. 3). In the meantime, even if the user swings down while standing up, the rotating frame 7 supporting the protruding rear seat plate 6b may suddenly drop due to the action of the gas spring 10. However, since it returns in a buffered manner against the urging force of the gas pressure,
No problem.

As described above, the standing assistance chair 1 according to the present invention is capable of standing up by raising the rear seat plate 6b with the help of the gas spring 10 when the user steps on the footrest 9 himself. Furthermore, the present invention can be applied to elderly people and patients with weak legs.
