Description

  The present invention relates to a handrail bracket for attaching a handrail to a wall surface such as a staircase or a hallway of a building.

  A bracket is generally used to attach the handrail to the wall surface. That is, the base portion of the bracket is fixed to the wall surface by screws or the like, and the handrail is attached to the handrail attachment portion at the tip of the bracket.

  To fix the bracket, usually hold the bracket with your hand and hold it with one hand to fix it with screws. However, it is difficult to fix the bracket accurately in this state. This is noticeable when tilting and mounting.

  In addition, the handrail attachment work usually requires the work of attaching the handrail to the wall surface before pasting the wallpaper such as a cloth, then removing the handrail and pasting the wallpaper, and attaching the handrail to the wall surface again. This is because an operator who performs wall surface construction and handrail attachment is different from an operator who applies wallpaper, and the working days of these workers are different.

  Therefore, when the handrail is attached to the wall surface together with the bracket again after the construction of the wallpaper, the handrail needs to be easily and surely attached to the original position. For example, in Patent Document 1, a positioning member is attached to a wall material, wallpaper is attached to the wall material so that the positioning member is exposed, and a handrail bracket is attached to the positioning member.

However, in the handrail bracket mounting structure described in Patent Document 1, it is necessary to attach the positioning member to the wall material in advance, and it is not always possible to easily attach the handrail.
