DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 to 6. A chair (1) is composed of a seat (2) and a seat (2).
It has a basic structure consisting of a leg (3) attached to the bottom surface of the vehicle and a backrest (4) standing on the back of the seat (2).

As shown in FIGS. 3 and 4, the leg (3) is formed by bending both ends of a leg frame (5) made of a metal pipe. Have been. The pair of leg frames (5)
It is screwed to the underside of the seat (2) so that
As shown in (1), the leg frame (5) is in a half-crushed state (5A) at the intersection, and is fixed by screws (6).

The backrest (4) is screwed to a pair of left and right L-shaped backrest frames (7, 7) which are screwed to the leg frame (5) which is screwed to the lower surface of the seat (2). Installed by

As shown in FIG. 6, the armrest member (8) is formed of a metal pipe, and both ends of the armrest member (8) are curved in a U-shape to form armrest portions (9, 9). The attachment portions (10, 10) are bent from the portions. The armrests (9, 9) are covered with a cushion cover (9A) made of a synthetic rubber foam, an elastomer foam or the like.

As shown in FIG. 3, the intermediate portion (8A) of the armrest member (8) and the mounting portion (10, 10) are screwed to a pair of leg frames (5, 5) crossing in an X shape. It is fixed to the bottom of the seat (2) by attaching it to the backrest frame (7, 7) with screws (6). Then, as shown in FIG. 1, the armrests (9, 9) at both ends of the armrest member (8) are in a state of rising upward from both sides of the seat (2) (state A). In this state b, the height of the upper end of the armrest (9, 9) is
The height is easy to support by hand when sitting or standing up. In addition, the armrests (9, 9) come to a position where it is easy to place the elbow.

As shown in FIG. 4, the intermediate portion (8A) of the armrest member (8) and the mounting portions (10, 10) are attached to the backrest frame (7, 10).
7) Attach to the back of the backrest (4) by attaching to each with screws (6). Then, as shown in FIG. 2, the armrests (9, 9) at both ends of the armrest member (8) are brought forward from both sides of the backrest (4) (state b). In this state B, the upper side or the lower side can be grasped and supported by the hand according to the body shape of the user. When a person leans his back on the backrest (4), the person is held by the armrests (9, 9), and the person is stably supported by the armrests (9, 9). In state a, if the height of the armrests (9, 9) is set to a height at which a person sitting on the floor can easily rest his / her elbows, the front end position of the armrests (9, 9) is equal to the front and rear width of the seat (2). Near the midpoint. Then, the person can sit on the chair (1) from diagonally forward or stand up diagonally forward without being interfered by the armrests (9, 9).

As described above, since the armrest member (8) is easily attached to the chair (1) by the screw (6), it is extremely easy to remove the attachment or to alternately change the state between the state A and the state B. . And this chair (1) has legs (3)
The height can be adjusted by expanding and contracting
The lower end of (3) is covered with a non-slip cap (11) made of rubber or elastomer, so that it can be installed stably even in slippery places such as bathhouses.

[0014]

According to the present invention, by changing the mounting position of the armrest member, the position of the armrest portion can be easily changed according to the body shape and the state of use.
