Abstract
To provide a double-deck elevator characterized by the fact that by increasing the story height adjustment range in the direction in which the two cars approach each other, it is possible to increase the degree of building design freedom. Two up/down cars (), () arranged in outer frame () are connected with each other by means of pantographic mechanisms () that can effect an expansion and contraction operation, and the two cars (), () are driven to move towards each other or away from each other by means of pantographic mechanisms (). The pantographic mechanisms () are arranged in the spaces between vertical beams () and the two cars (), () and each has a pivot point at the longitudinal central portion of vertical beams () extending vertically in outer frame (). Due to the pantographic mechanisms (), the story height adjustment range in the direction in which the two cars (), () approach each other is not restricted.
