Description

  The present invention relates to a handrail bracket for mounting a handrail on a wall surface. More specifically, when fixing to a corner of a wall, a mounting screw reliably captures the center of a column, thereby ensuring a reliable mounting strength. The present invention relates to a handrail bracket that can be secured.

  With the arrival of an aging society, the number of people who need handrails in bathrooms and corridors of housing is increasing year by year.

  The importance of handrails has a major impact on the lifestyle of the house. In other words, only those that lead to an improvement in ADL (Daily Life Operations) are desired to be attached to the user.

  The bracket used for attaching the handrail has many restrictions on the attachment position with respect to the wall in order to ensure safety.

  Of course, if it is a new construction, it is possible to ensure safety by reinforcing the mounting position in advance, but in the case of retrofitting, it is often necessary to reinforce the groundwork. For this reason, it takes time and effort for the construction, and a large amount of materials are required and the construction cost is increased. In addition, the base material is noticeable and the appearance is also deteriorated.

  In particular, when trying to fix the bracket to the corner of the wall, it is desirable that a column exists at a position opposite to the corner of the corner, and that the column is installed by screwing a mounting screw. Will have to be screwed diagonally.

Conventionally, as shown in FIG. 6, as a method of screwing a mounting screw obliquely into a column, a guide hole 4 of a mounting screw 3 is provided in a flange 2 provided at an end of the bracket 1, and this guide hole 4 is The tapered hole 4b is formed with a recess 4a in which the head of the mounting screw 3 is accommodated and a tapered hole 4b having a large diameter on the mounting surface side, and the flange 2 of the bracket 1 is in contact with the corner of the wall A. It is made to fix by screwing with respect to the pillar B, along with the mounting screw 3 along the taper surface (refer patent document 1).
