  As described above, the toilet handrail 1 includes the base member 10, the rear base member 11 on which the standing member 20 is erected, and the front base member 12 that projects forward from the standing position of the erected member 20. Since the front base member 12 is connected to the rear base member 11 and the upright member 20 so as to be movable outward in the left-right direction, the front base member 12 projecting forward is moved along the both side wall surfaces SW of the toilet. It can be installed in close proximity.

  Therefore, in the case of a toilet where an entrance is installed on the front side of the toilet A, unlike a conventional toilet handrail in which a pair of frames protrudes on the front side of the toilet on both sides of the toilet, the toilet A is moved from the entrance of the toilet. Since the floor surface of the toilet is greatly opened toward the toilet, when an elderly person with weak legs is seated on the toilet bowl, there is no risk of tripping over the base member 10 and falling down, and the sitting operation on the toilet bowl A can be performed smoothly. In addition, in the case of an elderly person who uses a wheelchair, the wheelchair wheel contacts the base member 10 when the assistant lifts the elderly person from the wheelchair and moves it to the toilet and seats on the toilet, There is no possibility that an assistant may crawl on the base member 10.

  Further, since the front base member 12 is detachably connected to the rear base member 11 and the upright member 20 via the slide base portion 13 and the slide portion 14, when the toilet handrail 1 is installed in the toilet, By storing the toilet handrail 1 in the toilet with the front base member 12 removed, and reattaching the front base member 12 in the toilet, it can be installed smoothly and reliably in a narrow toilet.

  In addition, since the pair of pressing members 35 that respectively press the left and right side wall surfaces SW of the toilet are attached to the main body portion, the left and right side wall surfaces SW of the toilet are pressed by the pressing members 35, so that the base member 10 is A reduction in installation strength due to the division into the rear base member 11 and the front base member 12 can be suppressed.

  In the above-described embodiment, the toilet handrail of the type in which the movable arm 43 pushes up obliquely upward so that the pressing portion 45 of the fixing member 40 contacts and presses against the curved upper outer surface b of the toilet bowl A has been described. However, the present invention is not limited to this. For example, as shown in FIG. 12, the present invention is applied to a toilet handrail 70 of a type in which both sides of the toilet bowl A are sandwiched by a pair of clamping members 75, 75. Can do. Specifically, the pair of base members 71, 71 are divided into a rear base member on which the upright member 72 is erected and a front base member that protrudes forward from the standing position of the upright member 72. The base member may be connected to at least one of the rear base member and the upright member so as to be movable outward in the left-right direction.

  In the above-described embodiment, the slide base portion 13 is fixed to both the rear base member 11 and the upright member 20, but the present invention is not limited to this, and the rear base member 11 and the upright member 20 of the rear base member 11 are fixed. What is necessary is just to adhere to at least one.
