Temporary locking means for temporarily locking the transport vehicle 3 to the bathtub body 2 when a part of the transport vehicle 3 enters the position inside the bathtub body 2 with the locked portion 27 provided in 17a. 28 is configured (see FIG. 7).

  Next, the structure of the locking tool 26 will be described. Since the locking members 26 arranged on the upper surfaces of the left and right guide rails 25 shown in FIG. 5 have the same configuration, hereinafter, the direction of the opening 4 is the front and the right direction when viewed from the side (in FIG. (Direction) will be described as an example. One end portion of the locking device 26 is attached to the upper surface of the guide rail 25 near the one end portion 25a by a movable shaft 30, and can be moved (rotated) horizontally in the upper surface direction with the movable shaft 30 as a fulcrum. The other end portion of the movable shaft 30 on the side opposite to the axis attachment position is a movable plate 29 having a substantially bowl shape in plan view formed on a mountain-shaped convex portion 29a.

  As shown in FIG. 7, the convex portion 29 a of the movable plate 29 is guided from the upper surface of the guide rail 25 by a torsion spring 31 whose one end is wound and fixed to the movable shaft 30 and the other end is fixed to the movable plate 29. The rail 25 is biased so as to project toward the inner side surface. A roller lever type limit switch 32 is fixed to the upper surface of the guide rail 25 in the vicinity of the rear direction of the movable plate 29. When this limit switch is turned on, the lock means 33 (see FIGS. 4 and 6) described later can be operated.

  More specifically, the locked portion 27 is a columnar protrusion 17b formed so as to slightly protrude upward at the front end portions of the left and right chassis frames 17a of the transport vehicle 3 (see FIG. 3).

  Next, the transport vehicle 3 that has entered the inner position of the bathtub portion 11 is drawn toward the peripheral surface 4a side of the opening 4, the peripheral surface 4a and the flat surface 19b of the transport vehicle 3 are pressed and fixed, and the opening 4 is The configuration of the locking means 33 that is watertightly closed by the upper body support portion 19 will be described. As shown in FIG. 4, the lock means 33 are respectively arranged at the front left and right positions of the bathtub body 2, and the configurations of the lock means 33 are the same as each other. The configuration on the right side (the configuration on the upper side in FIG. 4) as viewed from that side will be described as an example.

  A vertical frame 34 having a U-shape in side view is erected in the same direction so that the opening side faces inward on each surface facing the front-rear direction of the support frame 13 having a mouth shape in plan view. A mounting frame 35 extending in the direction is fixed, and a support plate 36 having a substantially right triangle shape in plan view is fixed to the mounting frame 35. The cylinder 37a bottom side of the actuator 37 is pivotally supported by the support plate 36, and the rod 37b tip is pivoted at the tip of the projection plate 38 which is provided on the mounting frame 35 and extends toward the opening 4 direction. The hook member 40 is pivotally attached to one end of a substantially S-shaped hook member 40 that is pivotally attached to the shaft 39, and the hook member 40 rotates in the horizontal plane in conjunction with the expansion / contraction operation of the rod 37b. Move.

  As shown in FIG. 4, a tip roller 49 is pivotally attached to the other end of the hook member 40 so as to be rotatable. As shown in FIGS. 1 and 2, a passage hole 42 of the hook member 40 is formed on the inner side surface 41 a of the protruding edge 41 that protrudes from the peripheral surface 4 a toward the front of the bathtub portion 11. The lock means 33 includes the actuator 37 and the hook member 40 described above.

  A metal plate 43 is attached via a block member or the like at the left and right end positions of the rear surface of the upper body support portion 19 of the transport vehicle 3 where the hook member 40 is in contact with and pressed. (See FIGS. 3 and 6). A protective cover 44 (access prevention member 45) is provided so as to surround the vertical direction and the rear direction of the metal plate 43. The protective cover 44 guards the approach of foreign matter between the hook member 40 and the metal plate 43 when the hook member 40 is rotated to press the metal plate 43.

  When the rod 37b is extended after the transport vehicle 3 has entered the inner position of the bathtub portion 11, the hook member 40 passes through the passage hole 42 as indicated by the one-dot chain line in FIG. The upper body support portion 19 is pulled in the direction of the peripheral surface 4a by being pressed against the metal plate 43 provided on the rear surface of the body support portion 19, and the flat surface 19b is pressed and fixed to the peripheral surface 4a (see FIG. 6). As a result, the opening 4 is watertightly closed by the upper body support 19. The upper body support part 19 plays the same role as a bathtub door that opens and closes the opening 4 of the bathtub body 2 and can be closed watertight.

  Next, the operation of the bathing apparatus 1 according to the present invention will be described. A bather is seated on the seat portion 18 of the transfer vehicle 3 in the transfer transfer posture, and the operation bar 46 provided horizontally on the rear surface of the upper body support portion 19 is gripped with both hands, and the transfer vehicle 3 is opened to the opening 4. Move to move in the direction. After moving the conveyance vehicle 3 to the vicinity of the bathtub main body 2, the seat portion 18 is erected so as to be in the bathing mode shown in FIG. The left and right side portions of the chassis frame 17 a of the transport vehicle 3 are made to enter the inside of the bathtub portion 11 while being in sliding contact with the respective guide rails 25.

  A bather seated on the chair portion 18 enters the bathtub portion 11 from the foot side, and the chassis 17 enters below the bottom wall surface 11 a of the bathtub portion 11. When the chassis 17 advances to a position below the bottom wall surface 11a, the columnar projection 17b formed at the tip of the chassis frame 17a comes into contact with one inclined surface 29aa of the convex portion 29a of the movable plate 29, and the movable plate 29 is twisted. The convex portion 29a is moved in a direction overlapping the upper surface of the guide rail 25 against the elastic force of 31 (see FIG. 7).

  When the chassis 17 is entered as it is, the cylindrical projection 17b passes over the convex portion 29a, and the movable plate 29 is returned to the initial position by the elastic force of the torsion spring 31, and at the same time, the movable plate 29 is engaged with the cylindrical projection 17b. Stopped. Thereby, the conveyance vehicle 3 is temporarily locked with respect to the bathtub main body 2 (the temporary locking means 28 acts) (refer FIG. 7).

  While the elastic force of the torsion spring 31 sets the holding force of the locking action slightly stronger so that the locking action of the locking tool 26 to the locked portion 27 is not inadvertently released, When the transport car 3 is pushed in, the movable plate 29 is set to be movable against the elastic force by pushing the transport car 3 with a normal force even if the bathing caregiver does not push it strongly. In addition, at this time, the flat surface 19b of the transporting vehicle 3 is in a state of slightly abutting against the surface of the seal packing 23, and it is not necessary to press the transporting vehicle 3 against the elastic force of the seal packing 23. , It does not become a work burden for bathing caregivers. When the temporary locking means 28 is actuated, a slight gap (for example, about 5 mm to 10 mm) is left between the flat surface 19b and the surface of the seal packing 23 so that both surfaces are separated and face each other. You may comprise.

  At the same time as the temporary locking means 28 acts, the roller lever of the limit switch 32 is pressed by the front end portion of the chassis frame 17a, and the limit switch 32 is turned on. This ON signal is transmitted to the control unit of the bathing apparatus 1 (not shown), and the control unit is in a state in which the transport vehicle 3 reaches a normal position with respect to the bathtub body 2 when the limit switch 32 is turned on. And the locking operation of the locking means 33 is permitted.

  Therefore, when the transport vehicle 3 is not in a normal position with respect to the bathtub body 2, the locking means 33 is erroneously operated, leading to an unfavorable situation in which the opening 4 cannot be watertightly closed by the upper body support 19. Can be avoided. In addition, as a result of applying a locking force to an inappropriate portion other than the metal plate 43 provided on the rear surface of the conveyance vehicle 3 against which the locking means 33 is abutted and pressed, there is no problem that the conveyance vehicle 3 is damaged or deformed. .

  Subsequently, the locking means 33 disposed at the left and right positions of the bathtub body 2 is locked to fix the flat surface 19 b of the transport vehicle 3 to the peripheral surface 4 a of the opening 4 by pressing. At this time, since the protective cover 44 is provided around the metal plate 43 of the transport vehicle 3 against which the locking means 33 is abutted and pressed, the bathing caregiver accidentally leaves his limbs in the vicinity of the metal plate 43. As a result of operating the locking means 33 in the state, it is possible to avoid the danger that the limbs are pinched between the locking means 33 and the metal plate 43, and bathing care work can be performed with more peace of mind.

  Hot water previously supplied to the hot water storage tank 15 is supplied into the bathtub portion 11 via the hot water transfer path to provide the bather for bathing. When bathing, the hot water in the bathtub portion 11 is drained, and then the locking action by the locking means 33 is released. In addition, in order to prevent the situation where the locking action of the locking means 33 is canceled by mistake before draining hot water, the lock action is locked so that the locking action cannot be released unless the hot water in the bathtub portion 11 reaches a predetermined amount or less. The operation of the means 33 may be controlled.

  By pulling the transport vehicle 3 away from the opening 4, the locking action by the temporary locking means 28 is released, and the transport vehicle 3 can be withdrawn from the bathtub portion 11. The locking action of the temporary locking means 28 is released when the bathing caregiver applies a necessary (normal) external force to the transport vehicle 3, so that no special operation other than the operation of pulling out the transport vehicle 3 is required. , No need for bathing caregivers to operate.

  Next, another embodiment according to the present invention will be described with reference to FIG. In the present embodiment, the configuration of the temporary locking means 28 in the above-described embodiment is the locking tool 26 provided on the carriage frame 17a side of the transport vehicle 3 and the locked object provided on the guide rail 25 side of the bathtub body 2. The configuration is made up of the unit 27. Since the structure of the locking tool 26 is the same as that of the above-described embodiment except for the point provided on the chassis frame 17a, detailed description thereof is omitted. The locked portion 27 is a locked pin 47 erected on the upper surface of the guide rail 25 and to which the locking tool 26 is locked.

  Needless to say, the present invention is not limited to the above-described embodiments, and various configurations can be adopted without departing from the spirit of the present invention. For example, the configuration of the locking tool and the locked portion may be other configurations other than the above-described embodiment, in summary, the flat surface on the transport vehicle side is strongly pressed against the peripheral surface direction of the opening of the bathtub body. Any configuration may be adopted as long as the transport vehicle and the bathtub main body can be temporarily locked when a part of the transport vehicle is moved to a position inside the bathtub main body that is not necessary.

  In the above-described embodiment, the configuration example in which the locking tool is disposed on the upper surfaces of the left and right guide rails has been described. In addition, the above-described embodiment is premised on a new hot water bathing system in which hot water used for bathing by one bather is drained once, and when another bather bathes, fresh hot water stored in a hot water tank is transferred to the bathtub. However, instead of this method, the hot water supplied to the bather's bathing is not drained, but once it is transferred from the bathtub part back into the hot water storage tank and then transferred to the bathtub part again when another bather takes a bath, the circulating bathing system is used. However, it does not depart from the spirit of the present invention.

  Further, the form of the transfer and transfer posture of the transport vehicle is not limited to the seat and chair form illustrated and described in the above-described embodiment. For example, although not shown, the seat surface portion is rotated with respect to the body support portion. It is difficult to take a standing posture by connecting the body and changing the form so that the seating surface part and the body support part become substantially horizontal by further increasing the inclination angle of the body support part with respect to the chassis. The transport vehicle may be configured such that the bather can be transferred to the vicinity of the bathtub body by being transferred to the transport vehicle in a supine posture.

  In the above-described embodiment, the flat surface 19b continuously formed from the left and right sides of the upper body support portion 19 of the transport vehicle 3 to the lower side and the peripheral surface 4a of the opening 4 are pressed and fixed, and the opening 4 is Although the configuration example in which the body support portion 19 blocks watertightly has been described, the present invention is not limited to this configuration example. For example, although not shown, a container-shaped member is provided from the left and right sides of the upper body support portion of the transport vehicle to the rear periphery, and a portion of this container-shaped member can face the peripheral surface of the opening of the bathtub body The flat surface and the peripheral surface of the container-shaped member may be pressed and fixed so that the opening can be watertightly closed with the container-shaped member (the conveyance vehicle has The opening may be watertightly closed with a member other than the upper body support portion).

  INDUSTRIAL APPLICABILITY The present invention can be expected to be applied to a bathing apparatus that transfers a bather who cannot take a bath by himself / herself, such as a physically handicapped person or an elderly person, into a bathtub while sitting on a transport vehicle and uses it for bathing.
