<p>PROBLEM TO BE SOLVED: To simplify components, and to easily conduct the execution of works in the connection of the bent section of a horizontal muntin such as a handrail for a stair. SOLUTION: The spherical receiving section 5u of the first joint member 5 and the spherical body section 6b of the second joint member 6 are fitted on mutual spherical surfaces for connecting a handrail 2 to a fitting 4 for a support at an arbitrary angle, a shaft section 6j unified with the spherical body section 6b through the slit groove(s) of the spherical surface section 5u is projected to the outside, and the front end of the shaft section 6j can be connected to the fitting 4. A uniting section 5c, with which the end section of the handrail 2 can be united, is combined and unified with the spherical receiving section 5u. A fixing screw 8 for fixing the opposite postures of the first joint member 5 and the second joint member 6 is installed to the spherical receiving section 5u.</p> |
