<p>PROBLEM TO BE SOLVED: To facilitate a mounting work by lifting a column while turning a handle and imparting a tension to a floor and a ceiling and fixing the column by a stopper and then, putting a balustrade with a screw groove on the bracket to screw it. SOLUTION: A vertically adjustable handle 3 is turned to lift a column 11 and impart a tension to a floor and a ceiling and fixed by a stopper 5. An adjustable bracket 9 for the balustrade is inserted in a dowel hole 8 and fixed thereto. Then, the balustrade with a screw groove is put on the bracket 9 and fixed with screws. The balustrade is utilized for vertical rails, lateral rails, stair rails, etc. Hence, a wall face is not required. Handrails can be easily fitted by using columns whose tension is imparted by the floor and the ceiling.</p> |
