When the inner cylinder part 29 moves up and down along the inner peripheral surface of the outer cylinder part 28, the movable projecting part 36 protrudes and descends in the direction of arrow D and contacts the grounding surface 37 along with the lifting and lowering. And exit from the ground plane 37.

  As shown in FIGS. 4 and 7, the first link mechanism 24 (projection state maintaining mechanism) is constituted by a first link 24 a to a fifth link 24 e.

  The first link 24a is L-shaped, one end side is rotatably attached to the frame 6 by a pin 38, and the first operation member (swivel operation pedal) 22 is attached to the other end side. A midway portion of the first link 24 a is connected to one end side of the linear second link 24 b so as to be rotatable by a pin 39. The other end side of the second link 24b is connected to one end side of the linear third link 24c. The other end of the third link 24c is rotatably connected to one end of the fourth link 24d by a pin 40. The other end of the fourth link 24d is rotatably connected to the pin 30 described above, and the middle portion is rotatably connected to one end of the fifth link 24e by a pin 41. The other end side of the fifth link 24e is rotatably connected to the pin 31 described above.

  The second link mechanism 25 includes a sixth link 25a and a seventh link 25b.

  The second operating member (brake operating pedal) 23 is fixed to one end side of the sixth link 25a. The other end of the sixth link 25 a is rotatably connected to the friction leg 21 by a pin 42. A midway portion of the sixth link 25a is rotatably connected to one end side of the seventh link 25b by a pin 43. The other end side of the seventh link 25 b is rotatably connected by a pin 44.

  The structure of the friction leg 21 is basically the same as the structure of the grounding leg 20, but the structure will be briefly described as follows with reference to FIG. . That is, the friction leg 21 includes an outer cylinder 21a, an inner cylinder 21b, and a movable protrusion 21c. The inner cylinder 21b is attached to the outer cylinder 21a via a compression spring (not shown).

  The outer cylinder 21a and the inner cylinder 21b have long holes 21d and 21d, respectively, and the pin 44 communicates with the inside and outside of the cylinder through the long holes 21d and 21d, and a tension spring (not shown) is pinned inside the inner cylinder 21b. 44 and the pin 42. When the second operating member (brake operating pedal) 23 is rotated in the direction of the arrow G against a tension spring (not shown), the sixth link 25a rotates counterclockwise around the pin 42 as the center of rotation. As a result, the seventh link 25b is lowered, and at the same time, the inner cylinder 21b is lowered in the outer cylinder 21a, and the movable protrusion 21c is lowered. When the movable protrusion 21c is lowered, the lower friction surface of the movable protrusion 21c comes into frictional contact with the ground contact surface 37. The friction surface of the movable protrusion 21c is provided with a member having a high friction coefficient. When the second operating member 23 is released, the pin 44 is pushed up by the tension spring, and the seventh link 25b pushes back the sixth link 25a in the clockwise direction, thereby returning the second operating member 23 to the original position.

  In the above configuration, when the first operating member (turning operation pedal) 22 that is in the non-operating state in the state of FIG. 4 is lowered in the direction of arrow F by the foot of the assistant, the first link mechanism 24 The link 24a rotates counterclockwise around the pin 38 as a rotation center. Then, the second link 24b is pushed in the arrow H direction.

  As a result, the third link 24c is also pushed in the same direction, and as a result, the fourth link 24d rotates counterclockwise around the pin 30 as a rotation center. As a result, the fifth link 24 e is also pushed downward, and the inner cylinder 29 of the grounding leg portion 20 is lowered against the tension spring 33. As a result, the movable protrusion 36 of the grounding leg 20 descends from the state of FIG. 4 as shown in FIG. When the first operating member 22 is further lowered in the direction of the arrow F from there, the compression spring 34 is pushed and contracted by the pin 31, so that even if there is a step on the grounding surface 37, the stepping of the operating member does not change and is stable. And can turn.

  When the movable protrusion 36 comes into contact with the ground contact surface 37, the assistant can turn the bathing transport device 1 at the position where the movable protrusion 36 contacts the ground contact surface 37 with the device operation handle 5 e. In addition, when the caregiver handles the bathing transport device 1 alone, the bathing transport device 1 can be easily handled. When the first operation member 22 is released, the pin 31 is pushed up by the tension spring 33, and the link 24e pushes the link 24d in the clockwise direction to return the first operation member 22 to the original position.

  In the state of FIG. 7, the fourth link 24d and the fifth link 24e of the first link mechanism 24 are arranged in a substantially straight line, but the pin 41 that connects the fourth link 24d and the fifth link 24e The first link mechanism 24 (protruding state) is located on the right side in the figure with respect to the straight position, and the so-called link is moved over, so that even if the assistant lifts his / her foot from the first operating member (turning operation pedal) 22. Since the movable protrusion 36 of the grounding leg 20 is maintained in a protruding state by the maintenance mechanism, the assistant can more easily rotate the bathing transport device 1. Further, since the compression spring 34 is provided, the link can be easily moved over by contraction of the compression spring 34 even when a person with heavy weight is riding.

  In the state of FIG. 7, when the movable protrusion 36 of the grounding leg 20 is in contact with the grounding surface 37, the wheel 8 a is also in contact with the grounding surface 37. When the movable protrusion 36 abuts on the ground contact surface 37, the wheel 8 a may be in a state of floating from the ground contact surface 37.

  In addition, when the second working member 23 that is in the non-operating state in the state of FIG. 4 is lowered in the direction of arrow G, in the second link mechanism 25, the sixth link 25a rotates counterclockwise around the pin 42 as the rotation center. As a result, the pin 44 moves down along the elongated holes 21d and 21d of the outer cylinder 21a and the inner cylinder 21b of the friction leg 21 via the seventh link 25b.

  As a result, the movable projecting portion 21 c is lowered together with the inner tube portion 21 b of the friction leg portion 21 and is grounded to the grounding surface 37. As a result, a brake is applied to the bathing transport device 1 during transport. In this case, when the second operating member (brake operating pedal) 22 is lowered in the direction of arrow G as shown in FIG. 4, a part of the second operating member 23 is partly moved in the middle of the lowering. Alternatively, a part of the first link 24a is contacted, and the first operating member (turning operation pedal) 22 is also operated to be lowered in the direction of arrow F at the same time. As a result, the movable protrusion 36 of the grounding leg 20 is also grounded to the grounding surface 37 as shown in FIG. 8, so that the bathing transport device 1 is braked at a total of three locations.

  The grounding leg 20 not only assists turning, but also serves as a brake. When the second operating member 23 is operated in the direction of the arrow G, the first operating member 22 is always interlocked. When the second operating member 23 is lifted up from the brake state in which the grounding member 20 and the frictional member 21 are grounded, the grounding state is released only for the frictional leg 21 and the grounding leg 20 is It becomes a state where it is in contact with the ground, and can turn while maintaining the braked position of the bathing transport device 1. Further, when the first operating member 22 is lifted from the brake state in the direction opposite to the arrow G direction, the second operating member 23 is also operated at the same time, so that the grounding leg 20 and the frictional leg 21 are released from grounding. The transport device 1 can be moved freely.

  In the state shown in FIG. 8, when the movable protrusion 21 c of the friction leg 21 is in contact with the grounding surface 37, the wheel 6 a is in contact with the grounding surface 37. When the movable projecting portion 21 c comes into contact with the ground contact surface 37, the wheel 6 a may be lifted from the ground contact surface 37. In the above-described embodiment, the grounding leg 20 is grounded via the compression spring 34, but may be directly grounded without the compression spring 34. Furthermore, in the above-described embodiment, both the grounding leg 20 and the frictional leg 21 are provided, but the frictional leg 21 may be omitted and only the grounding leg 20 may be provided. .

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
