A locking tool 76 is installed in the mounting hole 75 in a state of being pushed in the locking direction by the compression spring 77. On the other hand, 65, 66, 67, 68 and 69 are locking holes, which are formed on the lower surface of the fixing plate 60 with appropriate intervals. And the said rotation cylinder 70 rotates the circumference | surroundings of the said shaft body 61, and the said chair part E is a bathing state in the said bathtub main body 10 (state where the chair part E turned the back wall of the bathtub main body 10 back). 3 (the state of the phantom line in FIG. 3), the locking member 76 reaches the position of the locking hole 65 and elastically enters to make it impossible to rotate the rotating plate 74 and thus the rotating cylinder 70. And

  The locking tool 76 and the locking holes 65, 66, 67, 68, 69 correspond to the “second locking means” of the present invention.

   Reference numeral 78 denotes an operation lever which is installed on the outer surface of the rotary cylinder 70 so as to be swingable. The operating lever 78 is connected to the rear end of the locking member 76 via a bracket 79. Therefore, when the operation lever 78 is swung downward, the locking state of the locking tool 76 is released. In this state, if the chair portion E is turned and the direction thereof is changed, the locking member 76 reaches the position of another locking hole 66, 67, 68, 69, and elastically enters to enter the rotating plate. In turn, the rotation of the rotary cylinder 70 is locked. At this time, since the position of the chair part E can turn the front side by 180 degrees, the bather can easily sit on the chair part E. The operating lever 78 returns to the original state (locked state) as the locking tool 76 enters by the compression spring 77.

  By the way, the rear end of the operation cable P is hooked on the operation lever 78. For this reason, when the operation lever 78 is swung in the direction in which the locking tool (chair portion E) 76 is released, at the same time, the operation cable P is pulled, and the locking tool (the swing arm B) ) 56 is also canceled. That is, since the two locking points can be released by one operation, the caregiver is easy to operate. In particular, the operation lever 78 is more convenient because it is located in the vicinity of the operation tool 81 that is always held by the caregiver.

  Since the operation cable P is merely hooked on the operation lever 78, even if the operation lever 78 returns to its original state, it is not pulled (in the locking direction) accordingly, Only when the locking tool 56 of the swing arm D is in the locked state, it is pulled back to the original state (the state of FIG. 8). Therefore, after positioning the chair E with respect to the swing arm D, the swing arm D can be positioned with respect to the support arm B. That is, the caregiver swings from the hand of the operation lever 78. Since it can fix, the positioning of the chair part E with respect to the support arm B is easy.

  When using this lift device, first, the support arm B is fixed to the state shown in FIG. Then, the locking tool 56 enters the locking hole 45 to fix the swing arm D to the support arm B in the state shown in FIG. 3, and the locking tool 76 enters the locking hole 65 to move the chair. The part E is fixed to the swing arm D in the state shown in FIG.

  In this state, as shown in FIG. 2, the bather is seated on the chair portion E and fixed with the tightening belt 83. Thereafter, the motor M is driven to raise the support column 20 until the chair portion E reaches the height of the bathtub body 10 or more. In this state, the operation lever 78 is swung downward, the locking tool 56 is released from the locking hole 45, and the locking tool 76 is released from the locking hole 65.

  In this released state, the caregiver moves into the bathtub body 10 while suspending the chair portion E by holding the operation tool 81 of the chair portion E. At this time, the caregiver extends the slide type footrest 82 of the chair portion E, and places the bather's legs (see FIG. 11).

  In this state, the side wall surface of the bathtub body 10 is exceeded. After the chair portion E is moved into the bathtub body 10, the locking member 76 is elastically advanced into the locking hole 66 to fix the chair portion E to the swing arm D, and the engagement member 76 A stopper 56 is elastically advanced into the locking hole 46 to fix the swing arm D to the support arm B.

  In this state, the motor M is driven to lower the support column 20 until the chair portion E reaches the bottom in the bathtub body 10. In this state, the bather can take a bath.

  After bathing, the motor M is driven to raise the support column 20 until the chair portion E reaches the height of the bathtub body 10 or more. Then, in this state, the operation lever 78 is swung downward, the locking tool 56 is released from the locking hole 46, and the locking tool 76 is released from the locking hole 66.

  In this released state, the caregiver moves to the outside of the bathtub main body 10 while hanging the chair portion E by holding the operation tool 81 of the chair portion E. After the chair part E is moved out of the bathtub body 10, the locking tool 76 is advanced into the locking hole 65 to fix the chair part E to the swing arm D, and the locking tool The rocking arm D is fixed to the support arm B by allowing 56 to elastically enter the locking hole 45.

  In this state, the motor M is driven, and the column 20 is lowered until the bather's feet reach the floor surface of the chair portion E. And a caregiver pushes in the said slide type footrest 82 of the said chair part E, and makes a bather's leg part an original state (state of FIG. 2). And it can leave | separate from the bather's chair part E by canceling | releasing the fastening belt 83. FIG.

  In the present invention, if the one locking means is a second locking means for locking the swing of the chair portion with respect to the swing arm, for a caregiver operating while gripping the chair portion, Since the operation part (for the release operation) is located in the vicinity thereof, the chair part can be easily moved.

  Further, in this case, if the locking operation of the second locking means is performed in preference to the locking operation of the first locking means, the swing of the chair portion with respect to the swing arm is locked. Since the swing of the swing arm with respect to the support arm can be maintained later and can be locked at an appropriate position, the caregiver can fix the swing from the hand of the operation lever 78. The chair portion E is easily positioned with respect to the support arm B.

  In addition, if the said support | pillar unit is installed in the outer wall part of the said bathtub main body, since the existing bathtub main body can be used as it is, the use value improves further.

  In addition, if the said support | pillar unit is provided integrally with the wall part of the said bathtub main body, the said lift apparatus for bath itself will become compact, and will be easy to install.

Since this invention is easy to position a chair part for a caregiver, this invention can be utilized when moving a chair part to a bathtub main body.
