A tilting lever 28 that can be held by a bathing assistant is connected to the other side of the link 34. Therefore, the bathing assistant manually operates the tilting lever 28 and changes the position of the convex portion 31 of the support arm 30 with respect to the guide groove 32 so that the angle of the entire backrest portion 11 is selected from the above. It can be done.
More specifically, in FIG. 3, when the convex portion 31 is engaged with the horizontal groove 32a at the upper right end, the angle of the entire backrest portion 11 becomes 0 °, and then fits into the horizontal groove 32b one step below. An angle of 11 ° is obtained, and further, an angle of 33 ° is obtained when the vehicle goes over a mountain and fits in the horizontal groove 32c at the left end.

Further, the first backrest portion 11a can be tilted with the inclination angle of the first backrest portion 11a with respect to the horizontal line being larger than the inclination angle of the second backrest portion 11b with respect to the horizontal line as the bathtub 3 moves upward. It has become. Hereinafter, this configuration will be described with reference to FIGS.
A substantially U-shaped mounting bracket 53 is attached to each of the left and right upper positions of the back surface of the first backrest portion 11a, and a groove 54 extending in the front-rear direction is provided on the outer surface of each mounting bracket 53. Is formed. In addition, a protruding piece 51 is fixed to the inner surface of the rear end of each square tube 27, and one end of a rotating piece 55 that is rotatably attached to the tip end of the protruding piece 51 via a support shaft 52 is attached to the end. Thus, the insertion pin 56 provided at the other end of the rotating piece 55 is inserted into the groove 54 so as not to come out of the groove 54.

In addition, a lever piece 58 is provided between the opposing surfaces of the mounting bracket 53 on the rear side of the groove 54 so as to be rotatable about a rotating shaft 57 that spans the opposing surface. Each end is biased in the clockwise direction in FIG. 3 by a torsion spring 70 (see FIG. 4) that is interposed in the moving shaft 57 and fixed to the lever piece 58 and the mounting bracket 53, respectively.
A tilting roller 60 is pivotally attached to the rear end of the lever piece 58, and the roller shaft 60 a of the tilting roller 60 is inserted so as not to come out into the long holes 59 formed in the rear end portion of the opposing surface of the mounting bracket 53. The tilting roller 60 is free to move in the long hole 59.

  A protruding pin 61 is provided at the front end of the lever piece 58 on the side opposite to the axis attachment position of the tilting roller 60 so as to protrude toward the outer side of the stretcher 4, and rotates near the front end of the mounting bracket 53 on the inner side. A hook-shaped locking member 63 that can be rotated by a shaft 64 is provided so as to be locked to the protruding pin 61. A torsion spring 62 is interposed on the rotation shaft 64, and one end and the other end thereof are fixed to the locking member 63 and the mounting bracket 53, respectively. The locking member 63 is locked to the protruding pin 61 by the torsion spring 62. 3 and the convex portion formed on the locking member 63 abuts against the bolt 75 protruding from the inner surface of the mounting bracket 53, thereby restricting the clockwise rotation at the position shown in FIG. It has become so.

  When the locking member 63 is locked to the protruding pin 61, the insertion pin 56 is not movable in the groove 54, and the rotating piece 55 cannot rotate about the support shaft 52. Further, tilting with the joint shaft 16 of the first backrest portion 11a as a support shaft is prevented. The protruding pin 61 and the locking member 63 of the lever piece 58 are main components of the tilt preventing means 65 that prevents the first backrest portion 11a from tilting by an operation other than the lifting operation of the bathtub 3. .

  A square tube 35 having one side screwed to the lower surface of the flange receiving portion 12 and the other side extending to the vicinity of the tip of the second leg receiving portion 13b is provided in parallel to the left and right sides. A plate 37 in which a reverse concave groove 36 is formed is attached. An operation rod 38 is inserted into the left and right grooves 36, and one end of the operation rod 38 is fixed to the operation rod 38 and the other end is pivotally attached to the joint shaft 18. 71 is connected. A gripping member 39 (see FIG. 1) that a bathing assistant grips is provided at both ends of the operation rod 38.

  Accordingly, the stretcher 4 changes the position where the operation assistant 38 is fitted to the groove 36 by the bathing assistant holding the grip member 39, so that the leg receiving portion 13 is in the horizontal state and the mountain state in which the joint shaft 18 is the top. The form can be changed. When bathing in a posture in which the knees are raised, the leg receiving portion 13 is changed to a mountain shape.

  A plate 41 in which a horizontal groove 40 is formed is fixed to the inner side surface of each square tube 35 near the front and rear center position. One end of the plate 41 is pivotally attached to the horizontal member 22 so as to be rotatable. A convex portion 46 formed at the other end of the piece 42 is fitted. The horizontal groove 40 and the convex portion 46 constitute a restricting means 73 for restricting the seat portion 45 from tilting upward beyond a predetermined angle. Further, a rolling roller 43 is provided on the lower surface of the tip of each square tube 35.

  Therefore, when the bathtub 3 is moved up to a certain position, the rolling roller 43 comes into contact with the bottom wall 3d, and when the bathtub 3 is further lifted, the seat 45 (the collar receiving part 12 and the leg receiving part 13) is lifted by the bathtub 3. As a result, the entire seat portion 45 is configured to tilt integrally with the joint shaft 19 as a support shaft so that the front side (front side) of the seat portion 45 is positioned upward.

  Further, an arc-shaped plate 47 in which an arc groove 48 is formed is provided on the outer surface at the tip of the square tube 35, and this arc groove 48 is attached to the lower surface near the front end of the second leg receiving portion 13b and is not shown. An operation pin 49 that is normally urged in the direction of the arc groove 48 by a spring or the like is inserted. When the operation pins 49 on both sides are removed from the arc groove 48, the entire leg support portion 13 can be flipped upward with the joint shaft 20 as a support shaft, and when the back surface of the leg support portion 13 is cleaned, etc. To use.

  The stretcher 5 having a substantially rectangular shape in plan view supports the stretcher 4 on which the bather lies in a supine posture and transports the bather to the bathroom where the bathtub 3 is installed. 3, after being laid sideways and engaged in one long side direction, the stretcher 4 is transferred to the receiving portion 7 or conversely received from the receiving portion 7. On the stretcher 5, the stretcher 4 can take a posture in which the placement unit 14 is in a substantially horizontal flat state, and performs an operation of transferring a bather lying on a bed or the like onto the placement unit 14. It is easy (see FIG. 1).

  As described above, the inclination angle of the entire backrest 11 with respect to the horizontal line can be fixed on the stretcher 5 at an inclination angle of 11 ° or 33 ° in addition to 0 °. An inclination angle of 11 ° is set when handing the stretcher 4 to the receiving portion 7 side, while an angle of 33 ° is for bathers who cannot take a lying position when washing their backs or in a fully flat state. Used in cases.

  Although not described in detail, the stretcher 5 includes a four-node parallel link 67 disposed at four positions on the front, rear, left, and right, and a drive power source (not shown) that synchronously drives the four-node parallel link 67. Since the height position for supporting the stretcher 4 can be adjusted, the height position can be adjusted as necessary, for example, when washing the bather's body. The height position of the stretcher 5 that supports the stretcher 5 is usually such that when the stretcher 5 is placed sideways on the bathtub 3 and engaged, the guide rails 69 and 69 of the stretcher 5 and the guide rails 8 and 8 of the receiving portion 7 are connected. It is set at the same height and on the same straight line. In FIG. 1, reference numeral 68 denotes a step base on which the bathing assistant rides when the stretcher 4 is handed over to the receiving portion 7, and conversely, the stretcher 4 is received from the receiving portion 7 onto the stretcher 5.

Hereinafter, the operation of the bathing apparatus 1 described above will be described. The bathtub 3 is at a predetermined lower limit position, and the placing portion 14 of the stretcher 4 on the stretcher 5 is in a full flat state.
A bather lying on a bed or the like is transferred onto the placement unit 14. The position of the pillow 17 is adjusted back and forth according to the height of the bather. The stretcher 5 is steered and the one long side direction of the stretcher 4 is placed sideways and locked to the one long side direction of the bathtub 3 so that the leg side of the bather is located on the stepped surface 44 side of the bathtub 3. When the stretcher 4 is placed on the stretcher 5, the locking member 63 is locked to the projecting pin 61 and the tilt preventing means 65 acts, and the first backrest portion 11 a and the second backrest portion The first backrest portion 11a cannot tilt with the joint shaft 16 as a support shaft.

  During the transfer operation of the stretcher 4 toward the receiving portion 7, first, the inclination angle of the entire backrest portion 11 becomes 11 ° so that the tilting roller 60 of the stretcher 4 and the shoulder shower 10 of the bathtub 3 do not interfere with each other. Tilt forward. In order to prevent the bather from slipping into the bathing water of the bather during bathing, the leg receiving unit 13 holds the gripping member 39 in a state in which a finger is inserted into the grip hole 74 and the leg receiving unit 13 is lifted. By changing the position where the operating rod 38 is fitted to the groove 36, the angle may be changed to a mountain shape.

  Further, since the seat 45 on the stretcher 5 is regulated by the regulating means 73 so as not to be tilted upward by a predetermined angle or more, even if the leg rest 13 is lifted upward by some beat, the seat 45 is seated. The portion 45 can be prevented from tilting unnecessarily, and safety can be ensured.

  Thereafter, the bathing assistant unlocks the stretcher 4 locked on the stretcher 5 (not shown), gets on the step base 68, holds the grip 24, and slides the stretcher 4 toward the bathtub 3. To the upper surface of the receiving part 7. When the center lock pin 25 of the stretcher 4 is fitted into the fitting hole 26 of the receiving frame portion 7b and the proximity sensor 9 is turned on, and the proximity sensor 9 detects that the stretcher 4 is locked, the bathtub 3 can be lifted. (The state shown in FIG. 5A is obtained).

  The tilt prevention means 65 acts until the tilted surface 66 of the bathtub 3 comes into contact with the tilting roller 60 of the stretcher 4, and the tilt angle of the backrest 11 as a whole is the level before the start of the lifting operation of the bathtub 3. 11 degrees is maintained, however, when the bathtub 3 reaches the ascending position, the inclined surface 66 of the bathtub 3 comes into contact with the tilting roller 60, and when the bathtub 3 continues to move up, the tilting roller 60 becomes a long hole. 59, and the lever piece 58 is rotated counterclockwise in FIG. 3 with the rotation shaft 57 as a fulcrum. As a result, the locking state of the locking member 63 with respect to the protruding pin 61 is released. (Tilt prevention means 65 stops working). As a result, the first backrest portion 11a can be tilted forward with the joint shaft 16 as a support shaft in association with the upward movement of the bathtub 3 thereafter.

  The tilt of the first backrest portion 11a is restricted at the position where the insertion pin 56 contacts the inner wall of the front groove 54a (the state shown in FIG. 5B). When the bathtub 3 continues to move up further, the second backrest portion 11b starts to tilt forward with the joint shaft 19 as a support shaft in accordance with the upward movement of the bathtub 3. At this time, the convex portion 31 of the support arm 30 moves forward while sliding on the lower surface of the horizontal groove 32b.

  When the bathtub 3 rises to the predetermined upper limit position, the bathtub 3 automatically stops the ascending operation, and the inclination angle of the first backrest portion 11a with respect to the horizontal line at this time is 34 °, while the second backrest portion 11b The inclination angle with respect to the horizon is 19 ° (the state shown in FIG. 5C). Therefore, even when a short stature bather takes a bath, there is no worry that the back of the head and ears are immersed in hot water, and the bath can be performed safely.

  On the other hand, in the ascending process of the bathtub 3, the seat 45 receives buoyancy from the hot water, and when the bathtub 3 rises to a certain position, the rolling roller 43 of the stretcher 4 comes into contact with the stepped surface 44, and thereafter the bathtub 3. As a result of the seat 45 (the buttocks receiving portion 12 and the leg receiving portion 13) being pushed up by the stepped surface 44 with the ascending operation, the entire seat 45 is automatically tilted upward with the joint shaft 19 as a support shaft. The inclination angle of the seat portion 45 with respect to the horizontal line when the bathtub 3 reaches the predetermined upper limit position and the ascending operation is stopped is set to 5 °. This prevents the bather from slipping due to buoyancy during bathing.

When bathing is completed, the bath 3 is moved down to retreat. Accompanying the downward movement of the bathtub 3, the seat 45 is tilted back to the horizontal state.
On the other hand, along with the downward movement of the bathtub 3, the convex portion 31 of the support arm 30 moves backward while sliding on the lower surface of the horizontal groove 32b, and the movement is restricted at the rear end inner wall of the horizontal groove 32b. The second backrest portion 11b tilts backward so as to return to a position where the tilt angle is 19 ° to 11 °.

  When the bathtub 3 continues to move downward, the rearward tilting of the first backrest portion 11a is restricted at the position where the insertion pin 56 contacts the inner wall of the rear groove 54b, and the tilt angle of the first backrest portion 11a is 11 °. Return until. At this time, the first backrest portion 11 a is designed to be supported by the square tube 27.

In addition, when the inclined surface 66 and the tilting roller 60 are not in contact with each other, the tilting roller 60 moves downward in the long hole 59 by its own weight, and the lever piece 58 uses the rotation shaft 57 as a fulcrum in FIG. The locking member 63 is automatically locked to the protruding pin 61 of the lever piece 58 (the tilt preventing means 65 acts) in conjunction with this.
After the bathtub 3 is lowered to the predetermined lower limit position, the bathing assistant releases the lock between the stretcher 4 and the receiving portion 7, slides the stretcher 4 onto the guide rail 69 and receives it on the stretcher 5.

Next, a second embodiment of the present invention will be described with reference to FIG. In FIG. 6, the same or equivalent components as those in FIGS. 1 to 5 are denoted by the same reference numerals, and the description of the components is omitted unless particularly required. In the second embodiment, the square tube 35 in the first embodiment is a square tube 2 having one side attached to the joint shaft 20 and the other side extending to the vicinity of the tip of the second leg receiving portion 13b. Further, the collar receiving portion 12 is changed to a configuration in which the collar receiving portion 12 is attached to the pipe-shaped member 21 by using the joint shaft 19 and the joint shaft 20.
Therefore, when the bathtub 3 is moved up to a certain position, the rolling roller 43 comes into contact with the bottom wall 3d, and the leg receiving part 13 as a whole with the joint shaft 20 as a supporting shaft is accompanied by the raising operation of the bathtub 3 thereafter. It tilts so that the front side (front side) is positioned upward.

  Next, a third embodiment of the present invention will be described with reference to FIGS. 7 to 10, the same or equivalent components as those in FIGS. 1 to 6 are denoted by the same reference numerals, and the description of the components is omitted unless particularly required. The third embodiment is configured to suppress the upward tilting of the seat portion 45 except when the stretcher 4 is placed at a predetermined position on the receiving portion 7 on the stretcher 4 in the first embodiment. Attached.

  Hereinafter, this configuration will be described. A hook member 75 having an L-shape in side view is provided on the front side surface of the horizontal member 22 below the second leg receiving portion 13b at the center position in the left and right direction. The upright portions 75 b are inserted through insertion holes 82 formed in plate-like attachment members 74 arranged in parallel with the vertical position of the front side surface of the horizontal member 22, and the insertion holes 82 are formed by the plain washers 80 and the snap pins 81. The upright portion 75 b is rotatable with respect to the mounting member 74. Further, an upper portion of the upright portion 75b is formed in a bent portion 75a that is bent so that the front side extends horizontally from the upright portion 75b.

  A disc-shaped eccentric plate 76 having the upright portion 75b as an eccentric shaft is fastened by a nut near the lower end of the upright portion 75b. A tension coil spring 77 is interposed between the upright portion 75 b positioned between the upper mounting member 74 and the bent portion 75 a and the upper surface of the horizontal member 22, and the hook member 75 is attached to the stretcher 4 by the action of the tension coil spring 77. Except when it is placed at a predetermined position of the receiving part 7, it is normally maintained so as to be in the state shown by the solid line in FIG.

  Further, on the side surface of the square tube 35 on the side where the hook member 75 is provided, when the seat portion 45 is tilted upward, a hook pin 78 protrudes so as to be hooked on the bent portion 75a in the solid line state of FIG. In addition, by the configuration of the bent portion 75a and the hook pin 78, the upward tilting of the seat portion 45 is suppressed except when the stretcher 4 is placed at a predetermined position on the receiving portion 7.

  On the other hand, as shown in FIG. 9, when the stretcher 5 is placed sideways with respect to the bathtub 3 and is locked, the stretcher 5 is located near the center side surface position of the guide rail 8 of the bathtub 3 on the side where the leg receiving portion 13 of the seat 45 is located. Is fixed with a release member 79 having a trapezoidal shape in plan view that releases the hook of the bent portion 75a and the hook pin 78 described above by rotating the hook member 75 by 90 ° in a predetermined direction.

  Next, the operation based on the above configuration will be described. For example, when the stretcher 4 is on the stretcher 5, the hook pin 78 is hooked on the bent portion 75 a of the hook member 75, so that the operation of tilting the seat portion 45 in the upward direction is suppressed. However, after the stretcher 5 is placed sideways with respect to the bathtub 3 and locked, the stretcher 4 is passed in the direction of the receiving portion 7, so that when the slide of the stretcher 4 is started, the side surface of the eccentric plate 76 is inclined to the inclined side surface of the release member 79. By abutting against and being pushed by 79a, it starts to rotate clockwise in FIG.

  When the stretcher 4 is further slid so that the side surface of the eccentric plate 76 reaches the position along the side surface 79b of the release member 79, the hook member 75 is rotated by 90 ° from the initial position, and the center lock pin 25 remains in this state. Is inserted into the insertion hole 26 of the receiving frame portion 7b, and the stretcher 4 is locked at a predetermined position (solid line position in FIG. 10) of the receiving portion 7. Thereby, the hook between the hook pin 78 and the bent portion 75a is released, and the seat portion 45 can be tilted upward in accordance with the ascending operation of the bathtub 3 as described above.

When the bathing is finished and the stretcher 4 is moved in the direction of the stretcher 5 until the eccentric plate 76 is not in contact with the side surface of the release member 79, the hook member 75 is restored to the initial position by the action of the tension coil spring 77. Therefore, since the seat part 45 does not incline carelessly except that the stretcher 4 is placed on the receiving part 7, the bather on the stretcher 4 does not feel uneasy.
In addition, although detailed description and illustration are abbreviate | omitted, of course, it is also possible to attach the same structure to the stretcher 4 in 2nd embodiment.

  In addition, the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention.

The present invention, which can be applied bather such elderly or handicapped bathing equipment for bathing immersed in a bath at supine posture, the industrial applicability is high.
