BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stair handrail, and more particularly to a stair handrail that can be installed at any angle.

[0002]

2. Description of the Related Art Generally, stair handrails are installed by confirming the slope of each installation site, such as stairs and slopes of the structure to be installed, and by assembling the vertical bars in accordance with this slope. At the same time, the handrail main body is constructed by cutting the upper and lower ends of the horizontal rail in the longitudinal direction, and the handrail main body is fixed to the side surface of the vertical pillar standing on the floor surface in a butt-end shape via the fixing metal fittings. Then, it is supposed that it is fixedly supported on the column.

[0003]

However, this gradient is 3
30 ° to 45 specified by law based on 7 ° to 38 °
It is extremely difficult to standardize the handrail main body because it generally varies greatly depending on the installation site in the range of °, and it is inevitable that individual handrails will be made to order. There is a circumstance that high processing accuracy is required.

The present invention has been made in view of such circumstances, and the problem to be solved is that the handrail main body can be installed in common regardless of the gradient and the strictness of the processing accuracy is relaxed. There is a stair handrail that can be installed at any angle.

[0005]

In view of the above-mentioned problems, the present invention is directed to a handrail main body of a variable angle connecting unit body which is flexibly assembled and extended, and is arranged in a erected state between the upper and lower ends of the handrail main body. The upper and lower erection metal fittings, the pillar brackets fixed to the building skeleton, and the erection brackets fixed to the erection brackets to stand vertically, and fixed to the erection metal fittings at the intersections with the upper and lower erection brackets to set the angle. The present invention relates to a stair handrail with a freely installable angle, which comprises a handrail main body and a vertical support for fixing the support, and this is a means for solving the above problems as the gist of the invention.

[0006]

In the present invention, since the handrail main bodies which are freely bent and extended can be varied in angle, and the upper and lower erection metal fittings between them also follow the angles of these handrail main bodies, the angles are set according to the inclination. In this state, the erection metal fittings can be fixed to the vertical columns, which makes it possible to install stair handrails.
