  By the way, in the handrail bracket described in Patent Document 1, the bracket main body must be screwed to the washer member fixed to the wall surface with screws, and the work of attaching the handrail bracket accordingly. There is a problem that the property is inferior.

  The present invention has been made to solve the conventional problems as described above, and it is an object of the present invention to provide a handrail bracket capable of improving the workability of attachment work to a wall surface.

  According to the first aspect of the present invention, there is provided a washer member fixed to the wall surface, a bracket body provided with a handrail support member for supporting a handrail on the top, and fixed to the bracket body and detachably attached to the washer member. A base plate is provided, and a one-touch coupling structure is provided between the washer member and the base plate for one-touch coupling between the washer member and the base plate. The shape is set so that it can be covered.

  According to this configuration, since the one-touch coupling structure that couples the washer member and the base plate with one touch is interposed, the base plate is attached to the bracket body in advance, so that the handrail bracket is installed locally. At this time, the bracket main body can be attached to the washer member that is fixed to the wall surface in advance with a single touch through the one-touch coupling structure, and the workability of the handrail bracket construction is greatly improved.

  According to a second aspect of the present invention, in the first aspect of the invention, the one-touch coupling structure includes a plurality of first locking protrusions protruding at a regular pitch in a circumferential direction from a surface of the washer member facing the base plate. And a plurality of second locking protrusions that are provided on the base plate at an equal pitch so as to correspond to the first locking protrusions, and the first and second locking protrusions are Also, the base plate is shaped so as to be locked together by rotating the base plate in the circumferential direction.

  According to this configuration, the bracket main body is rotated around the center toward the second locking protrusion in a state where the second locking protrusion of the base plate corresponds to the first locking protrusion of the washer member. By performing the one-touch operation, the first and second locking protrusions are engaged with each other, whereby the bracket body is fixed to the wall surface via the washer member.

  As described above, since the attaching and detaching operation of the bracket body with respect to the washer member is performed by rotating the bracket body, the bracket body once attached to the wall surface and supporting the handrail via the handrail support member is washed for some reason. When removing the member from the member, the bracket body cannot be removed by rotating it unless the connection between the handrail and the handrail support member is canceled.

  Therefore, when the bracket main body is fixed to the washer member by screwing as in the prior art, the handrail can be removed from the washer member without rotating the bracket main body. The bracket main body is removed from the washer member in a state where it is still connected to the washer member, so that the inconvenience that the handrail that is no longer supported becomes unstable may occur. Since the handrail is removed from the bracket body in advance, the occurrence of such inconvenience can be prevented in advance, which is advantageous in terms of safety measures.

The two handrail support members so that the semicircular thick portions thus formed do not interfere with each other (that is, the semicircular thick portions of the handrail support members are brought into contact with the other disk respectively). By abutting them and fixing them to the top of the bracket body in this state, the opposing ends of the two handrails that should be adjacent to each other are supported by one bracket for handrails.

  Therefore, by arranging a plurality of handrails of a certain length in series and installing the handrail brackets at portions where the end faces face each other, a handrail of a predetermined length is disposed.

  The invention according to claim 4 is the invention according to claim 1 or 2, wherein the handrail support member is formed by a disk to which an end surface of the handrail is fixed, and the disk is fixed to a top portion of the bracket body. It is characterized by this.

  According to such a configuration, the end of the handrail is not unsightly by fixing the disc to the end of the handrail at the end of the plurality of handrails to be connected in series, and fixing the disc to the top of the bracket body. It is supported by the handrail bracket.

  According to the handrail bracket according to the present invention, since the bracket body also has a function as a cover for covering the washer member, the number of parts is reduced because there is no dedicated cover body for covering the washer member as in the prior art. Therefore, it is possible to achieve a reduction in parts cost and assembly cost.

  In addition, since a one-touch coupling structure is installed between the washer member and the base plate with one-touch coupling, the base plate is attached to the bracket body in advance, so that one-touch coupling is possible when the handrail bracket is installed locally. The base plate can be attached to the washer member fixed to the wall surface with a single touch through the structure, and the workability of the handrail bracket construction can be greatly improved.
