 FIG. 1 is a perspective view of a bathing chair according to the present invention, and FIG. 2 is a partially exploded view of the chair disclosed in FIG. According to the drawings, a bathing chair according to the present invention comprises a seat (1), a backrest (2) provided detachably and foldably, and a leg (1) foldable on the bottom surface of the seat (1). 3) and armrests (4) rotatably provided at the left and right edges of the seat.

On the bottom surface of the seat (1), two leg connecting pipes (102) whose both end edges are vertically bent are provided in parallel, and the two leg connecting pipes (102) are provided. An armrest connection pipe (12) and a support pipe (11) are provided in parallel with each other, and two backrest connection pipes (101) once bent vertically are provided orthogonally.

One end of the leg connecting pipe (102), which is bent vertically and extends downward, connects the leg (3) via the joint member (5). The joint member (5) includes an upper joint (51) formed by connecting a guide plate (512) provided with a guide groove (511) to a ring inserted into one end of the leg connecting pipe (102). A lower joint (52) formed by connecting two ears (521) corresponding to the guide plate (512) to a ring body to be inserted into the upper insertion end (311) of the leg (3). A rectangular through-hole (523) is formed at the upper end of each of the two ears (521). When assembling the upper joint part (51) and the lower joint part (52) to form a joint member that folds the leg part (3), the guide plate (512) of the upper joint part (51) is connected to the lower joint part. It is inserted between the two ears (521) of the part (52) and is fixed with a fixing bolt (53) and a fixing nut (54) having a rectangular cross section at the root of the shaft. The fixing bolt (53) is formed at the root portion so as to have a rectangular cross section corresponding to the rectangular through hole (523). Therefore, the leg (3) is fixed to the seat (1) and does not rotate around the fixing bolt (53).

The leg (3) connects two legs (3) corresponding to the front and rear. That is, a substantially T-shaped joint (6) is inserted into each leg from the upper insertion end (311), and both ends of the connecting pipe (32) are inserted into the joint (6).

The vertically bent one end of the backrest connection pipe (101) extends upward and is connected to the backrest (2) via the joint member (5) in the same manner as the leg connection pipe (102). Therefore, the leg (3) and the backrest (2) are formed by loosening the fixing bolt (53) as shown in FIGS. The chair can be folded by removing it from the through hole (523), and the volume of the entire chair can be reduced. Therefore, it is convenient to store chairs without taking up space. Also, since the legs (3) corresponding to the front and rear are connected by the connecting pipe (32), when one leg (3) is folded, the other leg is interlocked and folded. Operation is convenient.

The armrest connection pipe (12) has projections (121) formed at appropriate positions on both end edges, and a substantially T-shaped joint (6) is inserted and inserted, and the joint (6) is inserted. It is rotatably connected to the connection end of the armrest (4) through the connection. In this case, the projection (121) comes into contact with the inner wall of the joint (6). In this case, abrasion occurs due to friction on the inner wall of the joint (6), so that the protrusion (121) comes into contact more securely, making the joint (6) hard to come off, and rotating the armrest (4). The chair will be positioned at any angle and will not fall naturally forward or backward of the chair.

The free end of the armrest (4) is bent and extended in the direction of the backrest (2). The support pipe (11) is provided so as to protrude from the edge of the seat (1), and when the armrest (4) is used by tilting it forward of the chair, the free end of the armrest (4) is extended. The portion is supported on the edge of the support tube (11). Further, at a place where the support pipe (11) comes into contact with the extension of the free end of the armrest (4), a positioning protrusion (41) made of an elastic material is provided on the extension of the armrest (4). A positioning recess (110) is formed on the side.

In the bathing chair having the above configuration, the armrest (4) can be tilted to the backrest side, so that when the user sits down, he stands in front of the chair like a conventional chair. It is convenient and practical for older people, people with reduced mobility, or caregivers, because there is no need to rotate and sit back. Further, since the leg (3) and the backrest (2) can be folded, the space required for storing the chair can be reduced.

Further, in order to more reliably connect the armrest connection pipe (12) and the joint (6), the structure disclosed in, for example, FIGS. That is, the screwing plate (71) is welded inside at an appropriate distance from the edge of the support tube (11). A screw hole (710) is formed in the inner wall of the screwing plate (71). In addition, the opposing surfaces are chamfered along the circumference, and the tapered fixing blocks (72a) (72b) having the inclined surfaces (721a) (721b) formed therein are inserted into the armrest connection pipe (121). In this case, a substantially C-shaped contact body (73) in which a projection is integrally formed is provided in a space formed by the inclined surfaces (721a) and (721b). Further, each of the fixed blocks (72a) and (72b) is formed with a hole penetrating the center point in the axial direction.

When the joint (6) is inserted into the armrest connection pipe (12) having the above configuration, a fixing bolt (74) integrally formed with a separate knob (741) is attached to the fixing block (72 a). It is inserted into the hole of (72b) and screwed to the screwing plate (71). Therefore, the joint (6) does not come off from the armrest connection pipe (12). In this state, the projection of the contact body (73) is pushed upward by the inclined surfaces (721a) and (721b) of the fixing blocks (72a) and (72b), and comes into contact with the inner wall of the armrest connection pipe (12). When the armrest (4) is rotated, it is positioned at any angle and does not fall naturally forward or backward of the chair.

In the chair according to the present invention, as shown in FIG. 7, the shape of the seat (1 ') may be changed so that the buttocks do not slip off the seat during bathing. That is, a notch-shaped hole is formed from the front. Such a seat (1 ") is convenient because the caregiver can also wash the buttocks of the user while the user of the chair remains on the chair.

Further, as disclosed in FIG. 8, an armrest support portion (14) having concave grooves at both end edges of the seat portion (1 ″) is integrally formed to support the armrest (4). Good.
