Description

  The present invention relates to a handrail bracket, and more particularly to a disassembled handrail bracket that supports an end portion of the handrail.

  In general, a handrail bracket attached to a room, a hallway, or the like is fixed to a wall surface with a fixing screw such as a wood screw. For this reason, when replacing the wall paper or brackets that have become dirty due to long-term use, if the bracket is removed from the wall surface each time, the screw hole on the wall surface will become loose, which will hinder re-installation. is there.

  In addition, when replacing the wallpaper, the wall paper may be pasted without removing the brackets and avoiding the brackets and handrails, but this is time consuming and troublesome in terms of time and cost. is there.

  As a method for solving the above-described problem, it is conceivable to make the part for fixing the bracket to the wall surface and the part for supporting the handrail detachable. A handrail bracket including a base that is fixed to a wall surface and a bracket body that is detachably fitted and fixed to the base is known (see, for example, Patent Document 1).

  The conventional handrail bracket has a base-side fitting groove on a side surface of the base-side fitting portion provided on the base, and the base-side fitting groove is provided on a side wall of the fitting portion provided on the bracket body. The base-side fitting portion and the bracket-side fitting portion are fitted to each other so as to be fitted with the bracket-side fitting protrusion, and pass through the screw insertion hole provided on the mounting surface of the bracket body. In this structure, the fixing screw is screwed into a screw hole provided in the base.

  According to this handrail bracket, once the handrail bracket is fixed to the wall surface, the bracket body can be removed from the base by loosening the fixing screw of the bracket body without removing the base from the wall surface. There is no need to remove the base fixing screw when replacing the bracket.

The handrail bracket is also applied to support an intermediate portion and an end portion of the handrail.
