Abstract

The present invention provides an elevator apparatus in which a first car chamber and a second car chamber of a first car are relatively displaceable to a first position juxtaposed to each other in a horizontal direction and in an up-down direction. The second position juxtaposed with each other. The first car may be staggered with the second car when the first car compartment and the second car compartment are in the second position. A first front doorway and a first rear doorway are respectively provided in the first car room. A second front doorway and a second rear doorway are respectively provided in the second car room. On the back of the second car, there is a rescue entrance.

Description

technical field [0001] The present invention relates to an elevator apparatus in which first and second cars are independently raised and lowered in a common hoistway. Background technique [0002] In a conventional double-deck elevator (Double-Deck Elevator), first and second elevator cars arranged side by side vertically are suspended from suspension beams. In addition, the interval between the first and second elevator cars is changed by the driving force of a motor mounted on the suspension beam (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2000-309482 [0004] In the above-mentioned conventional double-deck elevator, although the floor area of ​​the car can be guaranteed to be about twice that of the same shaft area as usual, there is a problem that the upper car cannot stop at the lowest floor, and the lower car cannot stop at the lowest floor. Restrictions such as the upper floor, lack of convenience. Contents...
