Description

  The present invention relates to a connected elevator car that connects a plurality of elevator cars and simultaneously raises and lowers the plurality of elevator cars, and an elevator system using the connected elevator car.

In an elevator system of a high-rise large building, in order to shorten the time required to reach the target floor, the destination floor is divided into several banks such as a low-rise building, a middle-rise building, and a high-rise building. For this reason, a large number of elevator shafts are required, and the area occupied by the elevator shaft in the plan plan becomes large, and the construction cost is also increased.
In the conventional elevator system, one elevator car moves up and down on one elevator shaft to carry the user to the destination floor, and the transportation capacity is limited. A double deck elevator in which the elevator cages illustrated in FIG. 8 are connected up and down is known as one that increases the transportation capacity, and the transportation capacity of one plane is roughly twice that of a normal elevator. It is expected that it will exert great power in both space efficiency and operation efficiency.
However, since the two elevator cars are always in a vertical relationship, the boarding location is divided into two floors, and in order to reach the destination floor, make sure that the elevator car you are going to ride stops at the destination floor. In addition, if the elevator car stopped at the landing floor does not stop at the target floor, it is inconvenient to move the floor.
