<p>PROBLEM TO BE SOLVED: To set horizontal members mutually in any direction to improve work efficiency when work is executed at site, select a connection direction of the horizontal members freely to eliminate the restriction for an installation place, enable mass production to reduce cost, and improve the appearance and safety. SOLUTION: Engaging parts 10 of a pair of connection cylinders 4 which are connection members are engaged with any section of a spherical face of a spherical shape body 3. A wire 2 which is a ropelike member inserted into a hole 7 of the spherical shape body 3 is stretched and provided by a stretching means 5 in the connection cylinders 4 to set the connection cylinders 4 mutually in any direction and connect them through the spherical shape body 3. A handrail member 6 which is the horizontal member is fitted into the connection cylinders 4 and is fixed by screws 22. The inclined handrail member 6 is arranged on a side of an inclined part such as stairs. The connection cylinder which is the connection member is provided between spherical shape bodies 3 so that it can be applied to a curved part by increasing the number of the spherical shape bodies 3 and the connection cylinders provided therebetween.</p> |
