The height-adjustable chair according to the present invention is configured as described above. Therefore, the length of the legs, the positions of the stopper member, the back support member, and the seat plate can be arbitrarily selected and adjusted, and the form desired by the user can be obtained. can. In addition, due to its configuration, there is no risk of slipping or falling even when used in a bathroom or the like, and it is safe for the elderly and the physically challenged. It is a chair that can be used in a wide variety of ways.

It is a perspective view of the height-adjustable chair which carried out the present invention. It is also a front view. It is also a plan view It is also a bottom view It is also a side view. It is an exploded perspective view which was turned upside down. It is a figure which shows the attachment and the height adjustment of a leg part. It is a figure which shows the height adjustment of a back support member.

It was realized by showing it as a drawing and configuring it as described in the examples.

Next, an example of preferable implementation of the present invention will be described with reference to the drawings. 1 in the figure shows a height-adjustable chair in which the present invention is implemented. The chair 1 has a pair of downward U-shaped leg members 2 and 2 facing each other. The leg members 2 and 2 have a reinforcing rod 2a and 2a connecting the front and rear portions, and a central reinforcing rod 2b connecting the central positions of the reinforcing rods 2a and 2a, and the reinforcing rods 2a and 2b thereof. It is shape-retaining and reinforced.

The leg members 2 and 2 are formed of pipes, and a plurality of engaging holes 3a and 3a are arranged in a row in the U-shaped receiving pipes 3 and 3 in the vertical direction. On the other hand, 4 and 4 are legs that are fitted into the receiving pipes 3 and 3 via a joint short pipe 3b, and the legs 4 and 4 are provided with spring pins 5 urged by coil springs. By engaging the spring pin 5 with any engagement hole 3a of the receiving pipes 3, 3 ..., the height position of the legs 4, 4 ... Is selected and fixed.

Further, rubber stoppers (caps) 6, 6 ... For preventing slipping are covered and attached to the lower ends of the legs 4, 4, ... To prevent the chair 1 from slipping.
