The connecting pin 59 is fixed to the tip-side seat surface 57 with a set bolt (not shown) to prevent the connecting pin 59 from being separated from the connecting holes 56a and 58a.

The tip-side seat surface 57 rotates vertically about the connecting pin 59, and when it rotates downward as shown in FIG. 12, the stopper 58b integrally formed with the connecting portion 58 is formed. It abuts on the base-side seat surface 51 and is regulated to rotate in a horizontal posture. Hereinafter, this position is referred to as a lowered position. When the tip-side seat surface 57 rotates upward,
As shown in FIG. 5, one side of the connecting portion 58 abuts on the base end side bearing surface 51, and the rotation thereof is restricted in a slanting posture. Hereinafter, this position is referred to as a rising position.

On the outer circumference of the annular rib 44 of the main body 41,
A horizontally extending long hole 61 is provided so as to extend forward, and the base end of a rectangular stopper plate 62 is inserted into the long hole 61. The through hole 62a formed at the base end of the stopper plate 62 is fitted into the screw 54,

An endless metal belt 63 as an interlocking device is looped around the outer circumferences of the annular ribs 52 of the left and right base end side bearing surfaces 51 without any looseness.
It is fixed to the outer circumference of 2 with screws 64. Therefore, when one base end side bearing surface 51 is rotated horizontally in a specific direction, the other base end side bearing surface 51 is interlocked via the metal belt 63 and always rotates in the opposite direction by the same angle. However, the left and right base end side bearing surfaces 51 are within the range allowed by the elongated hole 61, that is, the approaching positions shown by the two-dot chain line in FIG. 13 and the mutual positions shown by the one-dot chain line in FIG. It rotates between the separated position and the separated position.

A lock spring 65 as a second angle holding means is wound around each of the left and right connecting pins 59 in a coil shape, and is closely attached to the outer periphery of the connecting pin 59 by its own elasticity. Both ends of the lock spring 65 are bent in mutually opposite directions, and one end 65a thereof has a connecting portion 5 of the base end side bearing surface 51.

It is hooked on a letter-shaped part. A damper 66 is fixed to one side of each of the left and right base end side bearing surfaces 51 of the connecting portion 56, and a buffer lever 66 a projects forward from each damper 66. The damper 66 biases the buffer lever 66a upward with a very weak torque to bring it into contact with the lower surface of the front end side seat surface 51, and when the front end side seat surface 51 rotates to the lowered position,
A predetermined resistance is applied by the buffer lever 66a to suppress the rotation speed thereof.

When the tip-side seat surface 57 in the lowered position shown in FIG. 12 is rotated to the raised position, the connecting pin 59 expands the diameter of the surrounding lock spring 65 by the frictional force, and the inner periphery of the lock spring 65 is While sliding between them, it rotates integrally with the tip side bearing surface 57. Therefore, the tip side bearing surface 5
The rotation of 7 to the raised position is easily performed without being restricted by the lock spring 65. When the leading end side bearing surface 57 in the raised position shown in FIG. 13 is rotated to the lowered position, the connecting pin 59 reduces the diameter of the surrounding lock spring 65 by frictional force, and the rotation is restricted by the lock spring 65. It Therefore, the rotation of the tip side bearing surface 57 to the lowered position is restricted by the lock spring 65, and as described above, the tip side bearing surface 57 in the lowered position is rotated to the raised position by an arbitrary angle. When moved, the tip side bearing surface 57 is held at that angle by the action of the lock spring 65. That is, it can be said that the winding direction of the lock spring 65 is selected so as to allow the connecting pin 59 to rotate to the ascending position side and to restrict the rotating to the descending position side. .. Since the left and right front end side bearing surfaces 57 rotate independently and are individually regulated by the lock spring 65, they can be adjusted to any different angles.

Further, when the release lever 49 is rotated upward when the tip-side seat surface 57 is in the raised position, the screw 54 described above is rich in elasticity, and as shown in FIG. The fixing pin 48 is rotated clockwise while slightly bending 54, and the stopper plate 62 is sent out slightly forward. As a result, the stopper plate 62
The other end 65b of the lock spring 65 hooked at the tip of the lock spring 65 is operated forward to expand the diameter of the lock spring 65, and the connecting pin 59
The rotation restriction of the lock spring 65 with respect to is released. Therefore, while the release lever 49 is being operated, the tip-side seat surface 57 can be rotated to the lowered position side.

As a result, the buttocks of the physically handicapped are supported by the left and right base end side bearing surfaces 51, the thighs are supported by the left and right tip side bearing surfaces 57, and the back of the physically disabled is supported by the backrest 33. Then, due to the weight of the handicapped person, a force to tilt the backrest 33 in the upright position to the tilted position acts,
As shown in FIG. 9, the lock spring 26 contracts in diameter and comes into pressure contact with the outer periphery of the horizontal bearing portion 16a, and keeps the backrest 33 in the upright position.

Next, the caregiver operates the controller to raise the chair 11 to move it to a position above the bath B, and further lower it to soak the chair 33 together with the chair 33 in the hot water in the bath B. Therefore, as shown by the solid line in FIG. 15, in the bathtub B, the disabled person takes a posture in which the legs are naturally extended while sitting on the chair 33, and the whole body of the disabled person is washed in the bathtub B by an attendant. ..

Here, for example, since the calf of a physically handicapped person is in contact with the bottom surface in the bathtub B, it is necessary to stand and wash the knees. Therefore, the caregiver uses the left and right tip-side seating surfaces 5
7 is gripped and each is rotated to the raised position. Figure 1
As shown in FIG. 3, the rotation of the connecting pin 59 expands the diameter of the surrounding lock spring 65 to allow the tip-side seating surface 57 to pivot to the raised position, so that the attendant can rotate the tip-side seating surface at any angle. 5
When the hand is released from 7, the lock spring 65 contracts due to the frictional force of the connecting pin 59, and holds the tip side bearing surface 57 at that angle. As a result, as shown by the phantom line in FIG. 15, the disabled person can take the posture in which his / her knees are upright with his / her thighs supported by the distal seat surface 57, and the calf can be washed by the attendant.

In this way, the tip side seat surface 57 is fixed at an arbitrary angle by the lock spring 65 by a simple operation of rotating the tip side seat surface 57 to the raised position, and the knee-standing posture is obtained. People with disabilities are retained. Then, the caregiver does not need to continue to operate the tip-side seat surface 57 in order to maintain the posture of the physically handicapped person, and can concentrate on cleaning the calf or the like.

To return the disabled person to the posture in which both legs are extended again, the release lever 49 is operated upward. Therefore, as shown in FIG. 13, the stopper plate 62 is slightly forwardly advanced with the rotation of the fixed pin 48, the diameter of the lock spring 65 is expanded, and the rotation restriction of the connecting pin 59 is released. 57 rotates to the lowered position due to the weight of the disabled person's leg, and the disabled person returns to the posture in which both legs are extended. When the tip-side seating surface 57 is rotated to the lowered position, the rotation speed is suppressed by the buffer lever 66a of the damper 66, so that both legs of the physically handicapped person are gently lowered and the physically handicapped person's legs are rapidly changed. The burden is prevented in advance.

Further, as shown by the solid line in FIG. 16, the physically handicapped person takes a posture in which both legs are closed in the bathtub B, and therefore it is necessary to open the legs when washing the crotch and the like. Therefore, the attendant grasps both legs of the physically handicapped person and opens them. As shown in FIG. 14, the left and right base end side bearing surfaces 51 on which the handicapped person is seated
Rotate together with the respective tip side bearing surfaces 57 by the metal belt 63 to the separated position. As a result, as shown by the phantom line in FIG. 16, the handicapped person takes the posture in which both legs are opened at the same angle. , The crotch can be washed by an attendant.
Since both legs of the physically handicapped are supported by the left and right base end side seating surfaces 51 and the tip side seating surface 57, the legs can be opened with a slight force with almost no resistance, and the help of the attendant can be reduced. Will be reduced. Further, not only when the legs are opened, but also when the both legs are closed after washing the crotch, it is possible with the same slight force.

Further, since the left and right base end side bearing surfaces 51 and the front end side bearing surfaces 57 are always rotated by the same angle in cooperation with the metal belt 63, the opening degree of both legs with respect to the body of the handicapped person can be increased. It becomes equal, and troubles such as one leg being greatly opened and burdening a physically handicapped person can be prevented.

For a physically handicapped person with one leg injured, if both legs are opened equally, the injured leg is rather burdened. Therefore,
In such a case, the metal belt 63 is removed so that the left and right base end side bearing surfaces 51 can be independently rotated. As a result, without moving the injured leg, only one healthy leg can be opened to wash the crotch and the like, and the burden on the physically handicapped person can be reduced.

Further, for example, to wash the hair of a handicapped person, it is desirable to wash the hair in a supine position that does not interfere with breathing. Therefore, first, the attendant operates the controller and reverses the above procedure to remove the disabled person from the bathtub B in the washing room B.
Then, the release lever 25 of the chair 11 is tilted backward. Therefore, as shown in FIG. 10, the lock spring 26 expands in diameter and comes into pressure contact with the inner circumference of the rotatable clamp cylinder 27, and the backrest 33 tilts to the tilted position following the release lever 25. Further, the rotation operating member 23 rotates rearward together with the release lever 25, and the main body 41, the base end side seating surface 51 and the tip end side seating surface 57 integrally rotate rearward on the operation surface 23c thereof, As a result, the seat 11 as a whole rotates rearward around the horizontal bearing 16a.

When the tilting operation of the release lever 25 is stopped at an arbitrary angle, the seat chair 11 is fixed at that angle. The weight of the disabled at this time is
Is applied to the main body 41 and acts in the direction of tilting the release lever 25 forward together with the rotation operating member 23 via the operation surface 23c, but the lock spring 26 contracts to reduce the seat chair 1.
1 is held at a predetermined angle. Therefore, as shown in FIG. 17, the handicapped person is changed to a supine posture, and the caregiver can wash the hair.

In this way, the seat 11 is fixed at an arbitrary angle by the lock spring 26 by a simple operation of tilting the release lever 25 rearward, and the disabled person is held in a supine posture. The caregiver does not need to keep holding the chair 11 in order to maintain the posture of the disabled person, and can concentrate on washing hair.

In order to return the disabled person to the normal posture, the backrest 33 is tilted to the upright position. Therefore, the lock spring 26 expands in diameter and comes into pressure contact with the inner periphery of the rotatable clamp cylinder 27, and the tilting of the backrest 33 to the upright position is allowed, so that the person with a physical disability and the seat chair 11 return to their normal postures.

On the other hand, as is clear from FIG. 15, the horizontal bearing portion 16a, which is the tilt center of the seat chair 11, is located at the rear end of the base end side bearing surface 51. Therefore, when the seat chair 11 is in a normal posture, the weight of the seated disabled acts on the front side of the horizontal bearing portion 16a, and as shown in FIG. 17, the seat lever 11 is tilted rearward by the release lever 25. In this case, the weight of the handicapped person acts near the horizontal bearing portion 16a. That is, in any case, the weight of the handicapped person does not act on the rear side of the horizontal bearing portion 16a, and even if the tilt regulation of the seat chair 11 is released due to a malfunction of the lock spring 26 or the like, It is possible to prevent inadvertent tilting of the chair 11 rearward.
