Therefore, it is not limited to the purpose of use of care or assistance, the assistance target is not limited to the cared person or the care recipient, and the person assisting the assistance target is also limited to the caregiver or the caregiver. Not something.

  In the bathing assistance apparatus 1, the fixing member has a function of attaching the bathing assistance apparatus 1 to the bathtub 8 as a base. The fixing member is not limited to this application example. The fixing member can be applied to various configurations other than the above application example.

<Overall structure of bathing support device 1 to which fixing member is applied>
The bathing assistance apparatus 1 includes a chair 2 that moves up and down in the bathtub 8, a driving device (driving unit) 3, an actuating member 4 that is actuated by the driving device (driving unit) 3 to raise and lower the chair 2, and an actuating member 4. It has an inclined frame 24 for guiding the up and down movement of the chair 2, and a fixture (fixing member) 10 for fixing the chair 2 to the bathtub 8 with the inclined frame 24.

  The chair 2 has a seat portion 2a on which a person sits and a backrest portion 2b on which the person's back is held, and is provided on the actuating member 4 and guided vertically along the inclined frame 24.

  The vertical position of the seat portion 2a is located between the upper and lower ends of the inclined frame 24. The seat portion 2a moves up and down along the inclined frame 24 by the operation of the operation member 4. The seat 2a may be held at a predetermined position between the upper and lower ends of the tilt frame 24.

  The seat portion 2a is provided on a horizontal flat base plate 2c. The horizontal portions 2e of the pair of pipe frames 2d are fixed to the side edges of the base plate 2c. The pipe frame 2d has a substantially L shape. The pipe frames 2d are provided in parallel in a direction parallel to the lateral direction of the edge wall 82 with the seat portion 2a interposed therebetween.

The backrest portion 2b mainly restricts the movement of the user to the back side, and the user sitting on the seat portion 2a can lean the back.
In the present embodiment, the backrest portion 2b includes a vertical portion 2f that is bent from the horizontal portion 2e in the pair of pipe frames 2d and extends upward in the vertical direction, and a strip-shaped cover material 2g that is installed between the vertical portions 2f. Has been formed. The horizontal portion 2e is provided with a guide pipe 2h slidably fitted on the outer periphery of the inclined frame 24. As a result, the user can fall backward and assist the user in maintaining the posture while taking a bath.

  The guide pipe 2h is connected to the actuating member 4, and contacts the lead-out portion 242 (see FIG. 2) of the fixed member body 20 when being guided by the tilt frame 24 and moved to the upper end side of the tilt frame 24. Thus, the guide pipe 2h is connected to the lead-out portion 242, and the upward movement of the guide pipe 2h is restricted. In this way, the guide pipe 2h functions as an operating member connecting portion that connects the operating member 4 and the fixed member main body 20 and restricts the movement of the operating member 4. The actuating member connecting portion may be constituted by a movement inhibiting member such as a pin provided in the moving region of the guide pipe 2h fitted on the inclined frame 24 so as to project in a direction intersecting the moving direction. The movement inhibiting member regulates the movement of the guide pipe 2h along the extending direction of the inclined frame 24, whereby the movement of the actuating member 4, and thus the chair 2, is regulated. The guide pipe 2h moves in the vertical direction by the operation member 4 operating in the vertical direction. At the time of this movement, the guide pipe 2h moves along the inclined frame 24, so that an obliquely upward force acts on the inclined frame 24. The fixture 10 is fixed to the bathtub 8 so as to support the inclined frame 24 by the force received from the guide pipe 2h.

  A handrail portion 2j extending in the horizontal direction is provided at the upper end of each vertical portion 2f so as to face the horizontal portion 2e. The handrail portion 2j assists the user in preventing the user from falling or sliding down and maintaining the posture. One of the pair of handrail portions 2j is rotatably attached to the vertical portion 2f, and is turned in the direction of the arrow X so that the posture of the handrail portion 2j changes from the horizontal state to the horizontal direction. The posture can be changed along the vertical direction deviating from just above the portion 2e. Accordingly, the handrail portion 2j does not interfere with the user when the user sits on the seat portion 2a of the chair 2, and the user can reliably sit on the seat portion 2a.

  The actuating member 4 is actuated by driving the driving device (driving unit) 3. In the present embodiment, the operating member 4 is arranged in the bathtub 8, and the chair 2 is attached to the upper portion thereof. In the present embodiment, the actuating member 4 is actuated by the drive of the driving device 3 and is provided so as to be able to extend and contract in the vertical direction.

  The operating member 4 includes a base member 41, a base plate 2c, and a telescopic member 42 having a lower end connected to the base member 41 and an upper end connected to a lower surface of the base plate 2c. That is, one end (upper end) of the elastic member 42 is fixed to the seat portion 2a via the base plate 2c. In the present embodiment, the actuating member 4 is a member that has a space inside and that expands and contracts by the inflow and discharge of fluid.

  The base member 41 is fixed to the lower end base plate 25 of the inclined frame 24, and is a member whose position is fixed during the lifting operation. The lower end base plate 25 is fixed on the bath bottom surface 81. The elastic member 42 has a filling portion (not shown) in which the fluid is filled. In the present embodiment, the elastic member 42 is a tubular body having a bellows shape with its top surface and bottom surface (both not shown) being closed, and its entire internal space serving as a filling portion. There is.

  By filling the filling portion with the fluid, the elastic member 42 expands and moves the base plate 2c upward, thereby raising the seat portion 2a of the chair 2 fixed to the base plate 2c. Further, as the fluid filled in the filling portion is discharged to the outside, the elastic member 42 contracts to lower the seat portion 2a of the chair 2 fixed to the base plate 2c. By such an operation, the chair 2 can be moved up and down inside the bathtub 8 between the bottom position and the upper position, which in the present embodiment is the same height or almost the same height as the fixing member main body 20. It has become. At least a part of the upper end of the elastic member 42 may be directly fixed to the chair 2. Since the inclined frame 24 is inclined, when the chair 2 stops at the upper position, the seat portion 2a is located near the edge wall 82 of the bathtub 8 (particularly the upper end surface 84 thereof). As a result, the user can easily enter and exit the bathtub 8 from the upper end surface 84 of the edge wall 82 of the bathtub 8.

  On the other hand, when the chair 2 stops at the bottom position, the seat portion 2a is separated from the edge wall 82 of the bathtub 8, so that the edge wall 82 does not interfere with the user taking a bath. The movement stop position of the seat portion 2a can be set at an arbitrary position by adjusting the filling amount and the discharging amount of the fluid in the filling portion. The fluid is not particularly limited as long as it is a substance having fluidity, but is water here.

  The drive device 3 is a device that drives the actuating member 4, and here, can supply the fluid to the filling portion of the elastic member 42 and discharge the fluid inside the filling portion of the elastic member 42. It is a device that can. The drive device 3 may be a mechanical device that provides a fluid to the working member 4, such as a pump or a fluid line. For example, when the fluid is water, the drive device 3 can be configured as a device that can be connected to supply water from a conduit for tap water having a predetermined pressure, a valve for water supply and drainage, or the like. The water supply path of the drive device 3 may be separate from or the same as the supply path for supplying hot water into the bathtub 8. In addition to the liquid supply pipe, the drive device 3 may include a liquid discharge pipe, a water intake port, a pump, a tank capable of temporarily storing a fluid, and the like as long as it can operate the operating member 4. May be provided.

The outer surface of the grip portion 52 is a curved surface, and is provided so as to project from the tip end side of the arm portion 60 and surround the rotation operation portion 71. As described above, since the grip portion 52 is arranged so as to surround the rotation operation portion 71, the user is prevented from colliding with only the rotation operation portion 71 and the user is not uncomfortable. .
Specifically, when the user enters or exits the bathtub 8, when the user puts his / her foot in the bathtub 8 while sitting on the pedestal surface 221, or moves his / her foot out of the bathtub 8, the turning operation is performed. The foot is not caught on the portion 71.
Note that the support portion 50 may be configured to support the load applied to the support portion 50, and therefore is configured to support the load transmitted to the support portion 50 by being applied to the pedestal surface 221 and thus the fixing member body 20. You may. For example, the support portion 50 may be the entire upper surface of the arm portion 60 or the entire movable holding member 30 (30-1, 30-2) including the entire arm portion 60.

The movement restricting member 70 connects the fixed member main body 20 and the moving portion 40, and restricts relative movement between the fixed member main body 20 and the moving portion 40.
Regulation of relative movement means that both the moving portion 40 and the fixed member body 20 are fixed at a position where relative movement cannot be performed. As a result, the fixed member body 20 and the moving portion 40 are fixed to the base body.

  The movement restricting member 70 restricts the movement of the moving portion 40 in the direction in which the fixing member main body 20 is separated from the contact frame 23 in the horizontal direction.

  The movement restricting member 70 is connected to the fixed member main body 20 via the arm portion 60 and the bolt 80. The movement restricting member 70 restricts the movement of the movement holding member 30 (30-1, 30-2) with respect to the movement amount of the movement holding member 30 (30-1, 30-2) with respect to the fixed body 20.

In the present embodiment, the movement restricting member 70 has a fitted tubular portion 72 and a rotatable operating portion 71 that constitutes the head of the fitted tubular portion 72.
The fitted tubular portion 72 has a tubular screwing portion 76 provided on the inner periphery on the side of the base end portion 72b. The screwing portion 76 is a female screw portion that is screwed with the bolt 80. The fitted tubular portion 72 is screwed to the bolt 80 by the screwing portion 76 in the central shaft portion 62 of the arm portion 60 of the movable holding member 30 (30-1, 30-2).
The turning operation portion 71 is fixed to the tip end portion 72 a of the fitted cylindrical portion 72, and is arranged so as to project from the outer periphery of the fitted cylindrical portion 72. The rotation operation part 71 is formed to be rotatable about the same axis as the fitted tubular part 72. A groove-shaped non-slip portion is formed on the outer periphery of the rotation operation portion 71 so that it can be easily rotated.

  When the turning operation portion 71 rotates about the axis, the fitted cylindrical portion 72 rotates about the axis and relatively moves with respect to the bolt 80 screwed by the screwing portion 76. Since the bolt 80 is fixed to the fixing member main body 20, when the rotating operation portion 71 is rotated in one direction, here, counterclockwise as viewed from the rotating operation portion 71 side, the bolt 80 and the screwing portion 76 are screwed together. The fitted fitted tubular portion 72 moves in a direction in which it is removed with respect to the bolt 80. As a result, the moving portion 40 can be displaced in the direction away from the fixed member body 20. In addition, when the rotation operation portion 71 is rotated clockwise as viewed from the rotation operation portion 71 side, the screwing portion 76 of the fitted tubular portion 72 and the male screw portion of the bolt 80 are screwed with each other and approached each other. As a result, the moving portion 40 approaches the fixed member body 20 and is fixed to the base body by sandwiching the base body interposed between the moving portion 40 and the contact frame 23.

The movement restricting member 70 also has an engaging portion that can support the load applied to the supporting portion 50.
The engagement portion of the movement restricting member 70 may contact the support portion 50 to support the load applied to the support portion 50, or support the load applied to the support portion 50 without contacting the support portion 50.
