  The universal attachment 47 is attached to the adjuster 46 through a universal joint, and has a certain degree of freedom according to the curved state of the upper outer surface b of the toilet bowl A as shown by a two-dot chain line in FIG. The contact angle can be adjusted.

  As shown in FIGS. 1 to 4, 6, and 7, the handrail member 50 protrudes downward from an armrest 51 in which a metal frame is covered with a resin cover, and a lower surface of the armrest 51. The arm 52 includes a pair of grips 52 that are connected to the rear end of the frame so as to sandwich the support member 23 of the upright member 20. The support member 23 is rotatably supported via the supported member 53.

  As shown in FIGS. 7 and 8A and 8B, the locking means includes a long hole 54 formed in a pair of supported members 53 and a long hole 54 that is movable in the long hole 54. The locking shaft 61 is inserted in a state where the locking shaft 61 is inserted, the guide hole 24 formed in the support member 23 into which the locking shaft 61 is movably inserted, and the supported members 53. It is comprised from the operation member 62 with which the front-end | tip was formed in the V shape, and was connected with the both ends so that rotation was possible.

  The guide hole 24 formed in the support member 23 includes an arcuate rotation hole portion 24a in which the locking shaft 61 moves as the handrail member 50 rotates, and a rear end portion of the rotation hole portion 24a. It is comprised from the linear locking hole 24b extended in the downward side, and is penetrated by the long hole 54 formed in a pair of supported member 53 as shown to Fig.9 (a), (b). The locking shaft 61 is moved between the front end portion and the rear end portion of the arcuate rotation hole portion 24a in the guide hole 24, so that the handrail member 50 has a predetermined armrest position and a flip-up position. It is designed to rotate between.

  When the handrail member 50 is rotated to a predetermined flip-up position, the long hole 54 formed in the supported member 53 has its longitudinal direction facing the vertical direction as shown in FIG. The locking shaft 61 that has been moved to the rear end of the rotation hole 24a falls in the long hole 54 so as to coincide with the locking hole 24b of the guide hole 24 formed in the support member 23. Then, by entering the locking hole portion 24b of the guide hole 24, the supported member 53 cannot be rotated with respect to the support member 23, whereby the handrail member 50 is locked.

  As shown in FIG. 4, the operation member 62 hangs down with the armrest 51 of the handrail member 50 facing the lower side when the armrest 51 is in a substantially horizontal armrest position. As the armrest 51 of the 50 is flipped up, it is lifted along the outer edge of the supported member 53, and when the handrail member 50 is locked at the predetermined lifted position, as shown in FIG. In this state, a finger can be put on the V-shaped tip.

  Therefore, when the handrail member 50 is locked at the predetermined flip-up position, when the operating member 62 is pulled up by placing a finger on the V-shaped tip, the locking shaft 61 to which the operating member 62 is connected is lifted. Since the guide hole 24 moves from the locking hole 24b to the rotation hole 24a, the handrail member 50 is unlocked, and the handrail member 50 can be rotated to the initial armrest position. .

  In addition, adjusters 11 and 11 for adjusting the height are attached to the front and rear ends of each base member 10 on the lower surface side, and the floor of the toilet is inclined in consideration of drainage and the like. Even if it exists, since height adjustment can be performed partially by each adjuster 11 and 11, the shakiness of the handrail 1 for toilet bowl installed can be eliminated.

  As described above, in the handrail 1 for the toilet bowl, the handrail member 50 has the grip 52 connected to the armrest 51. Therefore, an elderly person with weak legs sitting on a wheelchair jumps up the handrail member 50. In this state, when transferring from the wheelchair to the toilet A, the body can be supported by grasping the grip 52. Therefore, as compared with the case where the body is supported by directly placing a hand on the armrest that is flipped up, the body can be supported in a stable state, and the effect of being easily transferred to the toilet A can be obtained.

  In particular, in the handrail 1 for the toilet bowl, when the armrest 51 is flipped up to a predetermined flip-up position, the grip 52 protrudes in a substantially horizontal state and further forwards. The effect that it becomes easy for the elderly and the like who are trying to grasp the grip 52 is obtained.

  In the toilet handrail 1, the locking shaft 61 enters the locking hole portion 24 b of the guide hole 24 formed in the support member 23 only by lifting the handrail member 50 to a predetermined flip-up position. Since the handrail member 50 is automatically locked in the flip-up state, it is not necessary to perform a special locking operation. Therefore, when an elderly person or the like moves from the wheelchair to the toilet bowl A, an unforeseen situation occurs in which the handrail member 50 rotates to a predetermined flip-up position even if the body is supported by gripping the grip 52 of the handrail member 50 that has been raised. This makes it possible for an elderly person or the like to transfer to the toilet A with a sense of security.

  Further, after the elderly person or the like is seated on the toilet seat, the operating member 62 is pulled up to lift the locking shaft 61 that has entered the locking hole 24b of the guide hole 24 from the locking hole 24b. Since the lock of the member 50 can be easily released, the handrail member 50 can be immediately returned to a predetermined armrest position.

  In the above-described embodiment, the grip 52 is connected to the substantially central portion in the longitudinal direction of the metal frame constituting the armrest 51. However, the present invention is not limited to this. The position may be appropriately set in consideration of the height position of the grip 52 when the armrest 51 is flipped up.

  In the embodiment described above, the grip 52 is connected to the metal frame so as to protrude downward from the lower surface of the armrest 51. However, the present invention is not limited to this, and the outer portion of the armrest 51 is not limited thereto. A grip may be continuously provided on the side surface of the armrest 51 so as to protrude outward from the arm rest.

  Further, in the above-described embodiment, the lock unit that automatically locks the handrail member 50 when the handrail member 50 is flipped up to a predetermined flip-up position is employed. However, the present invention is not limited to this. It is also possible to employ locking means for manually locking the handrail member. Specifically, pin insertion holes that coincide with each other in a state in which the handrail member is raised to a predetermined flip-up position are provided on the support member fixed to the upper end portion of the standing member and the supported member fixed to the handrail member. It is possible to lock the handrail member in the flipped-up state by inserting a lock pin or the like into the pin insertion holes that coincide with each other in the state where the handrail member is jumped up to a predetermined flip-up position. Conceivable.

  The present invention can be used as a handrail for an existing Western-style toilet.
