Description

  The present invention relates to a handrail supported on upper ends of a plurality of support columns.

  In general, when installing handrails in hallways inside buildings, outside corridors and stairs of apartment buildings, or between the entrance and the gate of the site, multiple pillars are set up, and mounting brackets are attached to the upper ends of these pillars. The handrail is supported.

  By the way, the conventional handrail was formed in the substantially cylindrical shape, as patent document 1 shows. This seems to be derived from the fact that the handrail was a round bar since ancient times.

  However, when such a round bar-shaped handrail is put on the weight while being held by hand, such as when going down stairs, the load concentrates on a part of the palm and feels painful, and the bottom surface of the handrail is also round. So, when you go up the stairs, it is hard to get caught by your fingertips. Also, the mounting bracket is fixed on the lower surface of the handrail with a gap, so if you walk while holding it on the handrail, your fingers may hit the mounting bracket directly and feel painful, so that you will not hit the mounting bracket You must walk carefully.

Therefore, as in Patent Document 2, a handrail having a slightly flat cross-sectional shape as a whole has been proposed. Since the upper surface of the handrail is formed almost flat, when the body weight is applied while being held by the hand, the load is evenly distributed on the upper surface of the handrail, which makes it difficult to feel painful.
