It is assumed that.

According to a second aspect of the present invention, there is provided a handrail mounting device, a handrail, a wall on which the handrail is to be mounted, a cap nut, and a cap nut locking ring for locking the cap nut. A handrail mounting device comprising: a mounting screw for mounting the cap nut locking ring to the wall body; and a male screw capable of screwing the cap nut at the mounting end of the handrail. Separately, an engagement nut is provided, and an engagement portion for mutually engaging is provided at an attachment end of the engagement nut and the handrail, and an attachment screw is inserted into the attachment hole of the cap nut engagement ring from the back surface of the wall. The female screw engraved on the engagement nut is screwed from the tip of the mounting screw.

In the present invention, the wall is not particularly limited, but, for example, a wall to which a handrail is to be attached, such as a wall of a building, a wall of a counter, or a wall of furniture. Is included.

[0011]

In the handrail mounting device according to the first aspect of the present invention, the cap nut locking ring and the mounting end of the handrail are provided with mutually engaging portions, and the cap nut locking ring is provided on the wall. A mounting screw is inserted from the back into the mounting hole, and a female screw engraved on the cap nut locking ring is screwed from the end of the mounting screw. It is not necessary to attach a cap nut in advance, so that even if there is a corner in the wall surface, the cap nut does not interfere and the handrail can be firmly attached to the wall surface.

In the handrail mounting device of the present invention, an engaging nut is provided separately from the cap nut locking ring, and the engaging nut and the mounting end of the handrail engage with each other. The cap nut locking ring is such that a mounting screw is inserted into a mounting hole from the back of the wall body, and a female screw engraved on the engaging nut is screwed from a tip of the mounting screw. Therefore, it is not necessary to attach a cap nut to the wall on which the handrail is to be mounted in advance, so even if there is a corner in the wall, the cap nut does not interfere and the handrail is firmly attached to the wall. Can be installed.
