Embodiment Construction

[0011] Several embodiments of the present invention are illustrated below with accompanying drawings. Figure 1 to Figure 3 It is a figure of one Example of the elevator apparatus of this invention. figure 1 is the pattern diagram, figure 2 is its top view, image 3 is its side view. exist figure 1 In this case, two elevators 50 and 52 are adjacently installed in the hoistway wall (not shown). Since the configurations of the two elevators are almost the same, only elevator A will be described.

[0012] Elevator A machine 50 has a cage 1a for lifting and lowering. On the upper surface of the cage 1a, a cage-side pulley 7a is mounted. On the pulley 7a, a steel cable 5a having one end fixed to a cage-side cable fixing portion 6a is stretched. After the steel cable 5a is erected on the pulley 7a on the side of the cage, it is erected on the cable sheave 8a of the hoist 51. The hoist 51 is fixed in the machine room 55, and the machine room 55 is arranged near the top of the l...

Abstract

An elevator apparatus comprises two or more sets of elevators with one piece of an elevating passage. Each of the elevators has an elevator car and a hoist, which is connected to the elevator car through a rope. Each the hoist has a sheave, a motor and a brake. The hoist of one of the elevators is projected above the elevator car of the other elevator. Also, open / close doors of the one elevator and those of the other elevator are disposed, so that they shift in front and behind. Door cases of the juxtaposing elevators are disposed to overlap with each other in front and behind.

Description

technical field [0001] The present invention relates to an elevator device, and in particular to an elevator device in which a plurality of elevators are adjacently arranged in one hoistway. Background technique [0002] An example of an elevator apparatus in which two or more elevators are arranged in parallel is described in JP-A-2000-351537. In the elevator apparatus described in this publication, in order to improve the space efficiency of the building, a building wall is provided between the entrances and exits of two elevators, and an elevator control device is provided in the building wall. [0003] In the elevator apparatus described in the aforementioned Japanese Patent Laid-Open No. 2000-351537, in order to reduce the installation space of the elevators, attention is paid to the installation space of the control devices of the elevators installed in parallel. However, for high-lift or high-speed elevators, it is required not only to reduce the installation space o...
