Since it has the 1st and 2nd internal doors 27 and 28 which open and close a 2nd internal entrance and exit, it can manage suitably whether the 1st and 2nd elevator compartments 14 and 15 are moved.

In addition, since the 1st and 2nd internal doors 27 and 28 are each independently controlled to open and close, the 1st and 2nd elevator compartments 14 and 15 are positioned similarly to the double deck elevator in the state which located the 2nd position. The passengers can get on and off with the one landing 11. That is, the first and second elevator compartments 14 and 15 can lift and lower passengers in any of the first and second positions, and can improve the degree of freedom of the driving method. Moreover, when implanting in the state which located the 1st and 2nd elevator compartments 14 and 15 in the 2nd position, the space | interval of the 1st and 2nd elevator compartments 14 and 15 can also be adjusted according to an interlayer dimension.

Moreover, since the 2nd cage | basket | car 8 which has the 3rd cage 30 is suspended by the 2nd end part of the main rope 6, a transportation capacity can be improved significantly. In this example, twice as much transport capacity can be obtained in a hoistway space of about 1.5 times as compared to an elevator of a general structure.

Moreover, since the movable balance adjustment apparatus 4 is provided in the 1st cage | basket | car 7, the collapse of the balance by the displacement of the 1st and 2nd cages 14 and 15 can be suppressed. The balance adjusting device 24 detects not only the positions of the first and second elevator compartments 14 and 15, but also loads in the first and second elevator compartments 14 and 15, for example, to achieve a more optimal balance. You may make adjustment.

In the above example, the first and second elevator compartments 14 and 15 are each independently displaced, but the first and second elevator compartments may be displaced in conjunction with each other.

Moreover, even if it controls so that the displacement of the 1st and 2nd cage | basket | car compartments 14 and 15 may be completed before the 1st and 2nd cage | basket | cars 7 and 8 start running, you may control so that it may be carried out while traveling.

In addition, you may perform the displacement of the 1st and 2nd cage | basket | cab rooms 14 and 15 according to the call registration in the boarding point or the 1st and 2nd cage | basket | cab cage 14 and 15.

When the first and second cages 14, 15 in the first and second cages 58, 60 are both in the first position, the first and second cages 58, 60 in the vertical projection plane. ) Overlap each other. In contrast, when the first and second elevator compartments 14 and 15 in the first and second cages 58 and 60 are both in the second position, the first and second cages 58 and 60. ) Can be overlooked.

In such an elevator apparatus, by placing the 1st and 2nd cage | basket | car compartment 14 and 15 in a 1st position, it can arrange | position so that the 1st and 2nd cage | basket | cars 58 and 60 may mutually overlap in a vertical projection surface, In addition, by displacing the first and second cages 14 and 15 to the second position, it is possible to make the first and second cages 58 and 60 face each other. Therefore, the hoistway space can be reduced while ensuring sufficient car floor area. In addition, when the first and second elevator compartments 14 and 15 are positioned in the first position, the first and second elevator compartments 14 and 15 can be stopped on both the uppermost floor and the lowermost floor, resulting in reduced operational convenience. Can be prevented.

In addition, the operation of the first car 58 can be controlled only according to the call registration for the first car 58, and the operation of the second car 60 is directed to the second car 60. Since control can be made only according to call registration, efficient service can be provided for the passengers using the first and second cars 58 and 60.

In addition, the structure which has only one cage | basket | car may be sufficient as a 2nd cage | basket | car, similarly to the 2nd cage | basket | car 8 of Embodiment 1. FIG.

In addition, the 2nd lifting body and the 4th lifting body are not a balanced addition, It is also possible to set it as an elevator car.

In addition, the drive device for displacing the first and second elevator compartments is not limited to a screw lift device or a gear feeder, for example, a rope-type or pantograph-type. Various methods, such as hydraulic type, can be applied.
