  • a car deflector sheave 20 that guides the main ropes 18 from the driving sheave 17 to the car 4 and a counterweight deflector sheave 21 that guides the main ropes 18 from the driving sheave 17 to the counterweight 5 are mounted to the deflector sheave support beams 19.
  • the main ropes 18 are wound around a lower side of the driving sheave 17, and upper sides of the car deflector sheave 20 and the counterweight 21.
  • the driving sheave 17, the car deflector sheave 20, and the counterweight deflector sheave 21 are disposed such that their rotation axes are mutually parallel and extend horizontally.
  • the driving apparatus 15 is disposed in a position which is located lower than the car deflector sheave 20 and the counterweight deflector sheave 21 and where the driving apparatus 15 does not overlap with the upper beam 6 in a vertical projection plane thereof.
  • the driving apparatus 15 is disposed in a position such where at least a portion of the driving apparatus 15 overlaps with the car 4 in the vertical projection plane thereof. In addition, the driving apparatus 15 is disposed in a position where a portion of the driving apparatus 15 partially overlaps with the car deflector sheave 20 and the counterweight deflector sheave 21 in the vertical projection plane thereof.
  • a control panel 23 that controls the driving apparatus 15 and the like is fixed to a wall portion of the upper portion within the hoistway 1.
  • the control panel 23 is disposed within a region in which the landing door apparatus 11 and the car door apparatus 10 are disposed, as seen in a vertical projection plane thereof.
  • the rotation axes of the driving sheave 17, the car deflector sheave 20, and the counterweight deflector sheave 21 are disposed extending parallel to each other, and therefore work for installing the driving apparatus 15, the car deflector sheave 20, and the counterweight deflector sheave 21 can be performed easily.
  • the angle at which the main ropes 18 enter rope grooves of the driving sheave 17, the car deflector sheave 20, and the counterweight deflector sheave 21 can be made smaller. The lifetime of the main ropes 18 can thus be extended. That is, the rope grooves of the driving sheave 17, the car deflector sheave 20, and the counterweight deflector sheave 21 which correspond to the main ropes 18 can be disposed on one straight line, and the angle at which the ropes enter the rope grooves can be made substantially equal to 0°.
  • the driving apparatus 15 is disposed in a position which is located lower than the car deflector sheave 20 and the counterweight deflector sheave 21 and where the driving apparatus 15 does not overlap with the upper beam 6 in the vertical projection plane thereof. Accordingly, it is not necessary to extend a space within the hoistway 1 upward, even for cases where a large size driving apparatus 15 is used, provided that the driving apparatus does not interfere with the car frame 7 and the cage 8. The size in the vertical direction of the hoistway 1 can thus be made smaller. Further, the upper beam 6 does not contact the driving apparatus 15 even for cases where the car 4 ascends upward higher than an uppermost floor stopping position for some reason.
  • the driving apparatus 15 is disposed in a position at which a portion of the driving apparatus 15 overlaps with the car 4 in the vertical projection plane thereof, and therefore the cross sectional surface area of the hoistway 1 can be made smaller.
  • the driving apparatus 15 is disposed in a position at which a portion of the driving apparatus 15 overlaps with the car deflector sheave 21 and the counterweight deflector sheave 21 in the vertical projection plane thereof.
  • the cross sectional surface area of the hoistway 1 can therefore be made smaller.
  • the driving apparatus 15 is attached to the lower portions of the machine bases 12, and the car deflector sheave and the counterweight deflector sheave 21 are attached in the upper portions of the machine bases 12.
  • the driving apparatus 15 can therefore be disposed in a position that is located lower than the car deflector sheave 20 and the counterweight deflector sheave 21 by using common machine bases 12.
  • control panel 23 is disposed directly above the landing hall door apparatus 11 and the car door apparatus 10, and therefore the space within the hoistway 1 can be utilized effectively.
  • the machine bases 12 are supported by the structural beams 13 on the building side in the example described above, a structure may also be used in which the machine bases 12 are supported by, for example, at least either the car guide rails 2 or the counterweight guide rails 3. In this case, the load burden on the building can be reduced. Conversely, for cases where the machine bases 12 are supported by the structural beams 13, the load burden on the guide rails 2 and 3 is reduced, and the requisite strength of the guide rails 2 and 3 can be reduced.
  • a thin motor whose diameter dimension is larger than its axial dimension or a large cylindrical motor whose axial dimension is larger than its radial dimension may be used for the motor portion 16 of the driving apparatus 15.
  • the diameter of the driving sheave 17 may be set to a value that differs from at least the diameter of the car deflector sheave 20 or the car deflector sheave 21. Adjustment of the winding angle of the main ropes 18 to the driver sheave 17 can thus be performed.
  • Fig. 4 is an explanatory diagram that shows an example of a relationship between the diameter of the driving sheave 17 and the diameters of the car deflector sheave 20 and the counterweight deflector sheave 21 of Fig. 1 .
  • Fig. 5 is an explanatory diagram that shows another example. Adjustment of the angle at which the main ropes 18 are wound to the driving sheave 17 can thus be performed by changing the relationship between the diameter of the driving sheave 17 and the diameters of the car deflector sheave 20 and the counterweight deflector sheave 21.
  • adjustment of the angle at which the main ropes 18 are wound to the driving sheave 17 can also be performed by changing the distances among the driving sheave 17, the car deflector sheave 20, and the counterweight deflector sheave 21.
  • the driving sheave 17, the car deflector sheave 20, and the counterweight deflector sheave 21 can be made smaller by setting a ratio D/d to a value equal to or less than 20, where D is the diameter of the driving sheave 17, the car deflector sheave 20, and the counterweight deflector sheave 21, and d is the diameter of the main ropes 18. Saving of space in the hoistway 1 can also be achieved.
  • resin-covered ropes in which an outer layer covering made from a high friction resin material is provided in an outer peripheral portion thereof may also be used as the main ropes.
  • Fig. 6 is a side view that shows main portions of an elevator apparatus according to Embodiment 2 of the present invention.
  • the driving apparatus 15 is disposed so as to overlap with the counterweight 5 within a vertical projection plane thereof.
  • a portion 18c of each main rope 18 which extends from the counterweight deflector sheave 21 to the counterweight 5 passes between the driving sheave 17 and the motor portion 16.
  • Other structures are similar to those of Embodiment 1.
  • interference between the driving apparatus 15 and the upper beam 6 can be reliably prevented even if the depth dimension of the car 4 is small.
  • Fig. 7 is a side view that shows an elevator apparatus according to Embodiment 3 of the present invention.
  • the driving apparatus 15 is attached to the upper portions of the machine bases 12 through the driving apparatus support beams 14.
  • the deflector sheave support beams 19 are supported on the machine bases 12 through supports 24 above the driving apparatus 15.
  • the car deflector sheave 20 and the counterweight deflector sheave 21 are therefore supported by the machine bases above the driving apparatus 11.
  • Other structures are similar to those of Embodiment 1.
  • Work for attaching the driving apparatus 15 and the deflector sheaves 20 and 21 can also be made easier with this structure, and wear of the main ropes 18 due to contact with the rope grooves can be suppressed. Further, the size of the hoistway 1 in the vertical direction can be made smaller.
