Description

  The present invention relates to an angle adjustment mechanism for a handrail, and more particularly, to an angle adjustment mechanism that can securely fix a handrail member horizontally or to a predetermined inclination on a single column.

  A handrail installed on a floor or a passage generally has a structure in which both ends of a long handrail member are supported by columns. However, depending on the location, it may not be possible to dispose the support columns that support both ends of the handrail member. In such a case, the middle position of the long handrail member is supported by a single column. In the case of a handrail having a structure in which both ends of the handrail member are supported by the pillars, it is relatively easy to place the handrail members so as to be inclined according to the inclination angle of the floor or passage, but the latter is supported by one pillar. In the case of the handrail of the structure, since the handrail member and the support column are combined at one place, it is easy to set (adjust) the handrail member at an arbitrary angle, but it is securely fixed. It is not easy.

  As an example of a handrail having such a structure, for example, there is one shown in Patent Document 1. In the handrail shown in Patent Document 1, a headboard is formed into an elliptical shape, and an attachment member is interposed in an intermediate portion thereof and attached to one column. The angle of inclination of the headboard can be adjusted by meshing the surface gear portion of the mounting member with the surface gear portion of the member to be fixed, and the headboard is fixed by screwing through the insertion hole.
