FIG. 7 shows an assembly sectional view of the seat portion 7. The structure of the seat 7 is simple, easy to assemble and disassemble, and convenient for cleaning. Since the needle bearing 113 is held by the seat, it does not scatter even if it is disassembled.

  In order to bring the shower chair 1 for care into a folded state, the armrest 4 is flipped up, the front part of the base board 8 is rotated upward with the chair body fixed, and the snap fit between the base board 8 and the bar 51 is engaged. The joint is released and the seat 7 is flipped up. By a link mechanism (not shown), the front leg 5 and the rear leg 6 are closed in the front-rear direction in conjunction with the springing of the seat portion 7.

  When the care shower chair 1 is used, the rotation lock projection 97 of the seat base 9 is normally fitted into the locking hole 82A at the front center of the base board 8 to be in the rotation lock state. When rotating from this state to the right side, for example, first, the grip piece 94 is pulled upward to unlock the seat 9. Since the slits 95 are provided on both sides of the gripping piece 94 and the cushion 10 is also deformed, when the gripping piece 94 is pulled up, the rotation lock protrusion 97 is easily extracted from the rotation lock locking hole 82A. If the body is rotated to the right in this state, it can rotate freely up to 65 degrees to the right. In this range, the protrusion 98 on the back surface of the seat base 9 freely slides in the arc-shaped groove 83 on the top surface of the base board 8. In addition, when rotating a body, the armrest 4 is flipped up as needed.

  When the hand is released from the gripping piece 94 and rotated to the position of 65 degrees to the right, the protrusion 97 is fitted into the locking hole 82A positioned at 65 degrees to the right of the front part of the base board 8, and the rotation is locked. Further, even if the grip piece 94 is pulled up and rotated to 65 degrees or more, the protrusion 98 abuts against the end wall in the arc-shaped groove 83, so that rotation of 65 degrees or more is prevented. In this embodiment, the rotation range of the seat 9 is restricted by the arcuate groove 83 of the base and the projection 98 of the seat.

  The care shower chair 1 of the present invention can rotate the seat 9 so that it is easy to grasp a handrail on the wall surface when the care recipient stands up, and the awareness of independence becomes stronger, so that the caregiver can take care of the caregiver. This reduces the burden of washing your body. Moreover, even if the back is hidden by the backrest, the back can be easily washed by rotating the body. And since the rotation lock mechanism is provided, a sense of security is given to the user.

  In this embodiment, the rotation range is set to ± 65 degrees. However, if the rotation range is less than ± 45 degrees, the advantage of rotating the seat 9 is reduced, and if the rotation range exceeds ± 75 degrees, There is a risk that the upper body of the caregiver hits the backrest column 3 and the body is kinked. By restricting the rotation range, the user's body is prevented from hitting the backrest column 3, and there is no danger of falling even when a cared person with weak legs is used.

  Next, another usage of the care shower chair 1 will be described. When it is not necessary or necessary to rotate the seat 9 by the user, the bolt 12 with the knob on the back side of the base board 8 to which the seat 9 is attached is removed, and the seat 9 with the cushion 10 is put on. Remove from the base board 8 once. Next, the seat 9 is turned upside down and placed on the base 8 and set so that the rotation locking projection 97 fits into the rear locking hole 82B of the base 8 and is fixed again with the bolt 12 with the knob. . At this time, the protrusion 98 of the seat base 9 is fitted into the rotation lock locking hole 82 </ b> C in the front part of the base board 8.

  FIG. 8 shows this attachment state. Since the grip piece 94 is located on the rear side, the cared person does not accidentally pull up the grip piece 94. For example, something touches the grip piece 94 and the base Even if the rotation lock at the rear part of the board 8 is released, the rotation is also locked at the front part of the base board 8, so that the seat board 9 does not rotate unexpectedly and it is safe.

  In this embodiment, the bearing retainer 11 holding the needle bearing 113 is used. However, the present invention is not limited to this, and other bearings or a sliding member having a low friction coefficient may be used. Further, the number of the locking holes 82A can be freely selected.
