SLIDING DOOR

摘要

PROBLEM TO BE SOLVED: To stably and vertically transfer a door, by vertically providing a rail at the wall of two-story or higher building frame body and fitting a pair of upper and lower sliders with a vertically specified distance to a vertically movable door body and fitting the sliders to the rail. SOLUTION: A rail 12 is vertically provided at the front face side of a two- story or higher building frame body and a door body 4 provided with sliders 13 fitted to the rail 12 is installed to be vertically movable by a drive structure 3. The drive structure 3 is installed above the second floor or higher wall body H and the door body 4 so that a completely open space can be set at the first floor when the door body is raised. A pair of upper and lower sliders 13 are fitted to the door body 4 with a specified vertical distance. The door body 4 is supported at two positions at the same direction with the vertical direction of the door body. And hence, the door body can be vertically moved securely and stably.
