  Next, a reclining operation of the backrest 70 in the bath chair 10 will be described with reference to FIG. In the reclining operation, the lever 84 provided on the rear surface of the backrest 70 is pulled up and the abutting member 83 is rotated to operate which step 81 is the step 81 with which the abutting member 83 abuts. FIG. 4A shows a state in which the abutting member 83 is in contact with the upper stage 81a and the backrest 70 is raised most. The inclination angle from the installation surface is 65 degrees to 75 degrees. FIG. 4B shows a state where the abutting member 83 and the middle step 81b are in contact with each other. The inclination angle from the installation surface is 40 to 50 degrees. FIG. 4C shows a state where the abutting member 83 and the lower stage 81c are in contact with each other. The inclination angle from the installation surface is 10 to 15 degrees. In this way, the bath chair 10 can adjust the inclination angle of the backrest 70 in three stages.

  Next, the storage state of the bath chair 10 will be described with reference to FIG. When the bath chair 10 is stored, the backrest 70 can be tilted forward while the lever 84 provided on the rear surface of the backrest 70 is pulled up. As shown in FIG. 5, if the backrest 70 is tilted until the backrest 70 and the handle 40 lightly contact each other, the bath chair 10 can be made compact so that it can be easily stored.

 Alternatively, as shown in FIG. 6, the bath chair 10 can be stored vertically. That is, in the bath chair 10, if the handle 40 is removed from the base 20 by simultaneously pressing the two right and left release push buttons 52, the backrest 70 is moved forward until the front upper end portion of the backrest 70 slightly contacts the raised portion 23. Can be defeated. Further, when the handle 40 is attached to the base 20 again in a state where the backrest 70 and the raised portion 23 are lightly in contact with each other, the backrest 70 can be stored in a state in which the rotation of the backrest 70 is restricted by the handle 40. Thereby, it is possible to prevent the backrest 70 from rotating unexpectedly. The bath chair 10 can be placed so that the handle 26 is on the upper side with the handle 40, the backrest 70 and the front end portion of the pedestal 20 facing down. In this way, it can be stored compactly even in a narrow bathroom. In addition, the handle 26 can be easily grasped and the bath chair 10 can be easily carried.

  Next, the handle release / support mechanism 50 will be described in detail with reference to FIG. FIG. 7 shows a state where the handle 40 is detached from the base 20 and the right connection member 51 of the handle release / support mechanism 50 is disassembled.

  First, a description will be given based on the left connecting member 51 in the assembled state in FIG. The connection member 51 is formed in a substantially cross shape when viewed from the side. The bulging portion 51a extending in the front-rear direction at a substantially intermediate position in the vertical direction of the connecting member 51 has a flat bottom surface. An insertion protrusion 51b is formed downward from the bottom surface of the bulging portion 51a. On the outer surface of the connection member 51, a release push button 52 projects in the outward direction. On the outer surface of the insertion projection 51b below the release push button 52, a locking projection 53 similarly projects outward.

  Next, a description will be given based on the right side connection member 51 in FIG. The main body of the connecting member 51 is divided into an inner main body 51c and an outer main body 51d, which are divided into an inner side and an outer side of the bath chair 10. A handle support shaft member 54 is provided in an upper part of the connection member 51, and is fixed by being sandwiched by a hole formed by a semicircular notch 51c1 above the inner main body 51c and a semicircular notch 51d1 above the outer main body 51d. The The handle support shaft member 54 is formed with a flange portion 54a to prevent the connection member 51 from falling off.

  On the other hand, the above-described release push button 52 and the locking projection 53 are connected by a release member 55 on the back side (in other words, inside). That is, the release push button 52 and the locking projection 53 are integrally formed as the release member 55. The release member 55 is formed in a substantially strip shape when viewed from the side. A shaft portion 55 a is formed on the upper end portion of the release member 55. The shaft portion 55a is rotatably held by a bearing 51d2 of the outer main body 51d. Further, a recess 55b is formed on the back side (in other words, inside) of the release push button 52. And the pin 51c2 is standingly arranged in the position facing the recessed part 55b toward the outer side from the surface of the inner side main body 51c facing the outer side main body 51d. A coil spring 56 is wound around the outer periphery of the pin 51c2 in a compressed state. One end of the coil spring 56 is in contact with the outer surface side of the inner main body 51 c of the base end portion of the pin 51 c 2, and the other end of the coil spring 56 is in contact with a recess on the back surface side of the release push button 52. Accordingly, the release member 55 is urged toward the outside direction.

  On the other hand, the top portion of the support portion 24 of the pedestal 20 is formed with a flat surface matching the lower surface of the bulging portion 51 a of the connection member 51 as the top flat surface 24 a. An insertion hole 24b is provided downward from the top flat surface 24a. The insertion hole 24b is a rectangle that is long in the front-rear direction when viewed from above, and has a bottom 24b1. On the outer wall surface of the inner wall surface of the insertion hole portion 24b, a locking hole portion 24b2 for locking the locking projection 53 is opened. The insertion protrusion 51b of the connecting member 51 is inserted into the insertion hole 24b, and the lower surface of the bulging portion 51a and the top flat surface 24a are brought together. At the same time, the locking projection 53 is locked in the locking hole 24b2, and the upward movement of the connecting member 51 is restricted.

  Since the lower side of the locking projection 53 is inclined, when the insertion projection 51b is inserted into the insertion hole 24b, the locking projection 53 resists the outward biasing force. It is pressed by the outer wall surface of the insertion hole 24b. When the locking projection 53 reaches the locking hole 24b2, the locking projection 53 is urged outward, so that the locking projection 53 enters the locking hole 24b2. Since the locking projection 53 has a flat upper surface, when the locking projection 53 enters the locking hole 24b2, the upper surface of the locking projection 53 and the edge of the locking hole 24b2 contact each other. It will be in a contactable state and will be locked.

  On the other hand, the bearing portion 46 of the handle 40 is formed with a hole in the facing surface between the two forks. Both ends of the handle support shaft member 54 are fitted into the holes, and the handle 40 is supported so as to be rotatable around the handle support shaft member 54.

  In the state where the connection member 51 is attached to the pedestal 20, the outer surfaces of the connection member 51 and the support portion 24 of the pedestal 20 are formed as continuous outer surfaces having no irregularities.

  As described above, in the handle release / support mechanism 50 according to the present invention, the locking projection 53 of the connection member 51 and the locking hole 24b2 of the insertion hole 24b are locked to the outside of the left and right connection members 51. It can be released by one release push button 52 provided on the side. Therefore, the release operation of the connecting member 51 for opening and closing the handle is easier than in the case where the push buttons are arranged in two places in the front-rear direction. Since each of the left and right connecting members 51 rotatably supports the handle 40, the handle 40 can be opened from either the left or right side, making it easy to use even in a bathroom where installation space is limited. ing.

  Furthermore, since the upper surface of the support portion 24 is formed as the top flat surface 24a, when the handle 40 is closed, the insertion hole portion 24b into which the insertion protrusion 51b is inserted is easily visible. In addition, the dividing line between the connection member 51 and the support portion 24 is linearly formed in a side view, and the outer surfaces of the connection member 51 and the support portion 24 are also continuously formed without unevenness. It can be a chair. The connecting member 51 has a simple structure such that the release push button 52 and the locking projection 53 are integrally formed as a release member 55, and the upper end of the release member 55 is rotatably supported. Therefore, the manufacturing cost is reduced and the durability is good.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this, A change can be suitably added within the scope of the present invention. For example, although the insertion hole 24b is formed in a rectangular shape when viewed from above, it may be a square or an ellipse. In addition, the connection between the connection member 51 and the bearing portion 46 may be reversed so that the upper portion of the connection member 51 is bifurcated to support the handle 40 in a rotatable manner.
