Abstract
Official abstract text for this publication.
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 ( 6 ), ( 7 ) arranged in outer frame ( 5 ) are connected with each other by means of pantographic mechanisms ( 11 ) that can effect an expansion and contraction operation, and the two cars ( 6 ), ( 7 ) are driven to move towards each other or away from each other by means of pantographic mechanisms ( 11 ). The pantographic mechanisms ( 11 ) are arranged in the spaces between vertical beams ( 5 a ) and the two cars ( 6 ), ( 7 ) and each has a pivot point at the longitudinal central portion of vertical beams ( 5 a ) extending vertically in outer frame ( 5 ). Due to the pantographic mechanisms ( 11 ), the story height adjustment range in the direction in which the two cars ( 6 ), ( 7 ) approach each other is not restricted.
First claim
Opening claim text (preview).
The invention claimed is: 1. A double-deck elevator comprising: two elevator cabs: a frame that supports the cabs, the frame being at least partially situated on an outside of the cabs with spacing between the frame and the cabs, the frame being arranged in a hoistway such that the frame can move vertically for carrying the cabs along the hoistway; a support member that supports the frame within the hoistway; a machine associated with the support member, the machine causing…
