Definitions

  • the present invention has been made to solve the above-mentioned problem, and it is therefore an object of the present invention to obtain an elevator apparatus which makes it possible to reduce a space for a hoistway and prevent a deterioration in operational convenience while ensuring a sufficient car floor area.
  • An elevator apparatus includes: a drive device having a drive sheave; a main rope wound around the drive sheave; and first and second elevating bodies suspended by the main rope, for being raised/lowered within a hoistway by the drive device, in which: the first elevating body has a first car chamber capable of accommodating passengers and a second car chamber capable of accommodating passengers; and the first car chamber and the second car chamber are each relatively displaceable to a first position at which the first car chamber and the second car chamber are aligned with each other horizontally, and to a second position at which the first car chamber and the second car chamber are aligned with each other vertically.
  • Fig. 1 is a lateral view showing an elevator apparatus according to Embodiment 1 of the present invention.
  • Fig. 2 is a plan view showing the elevator apparatus of Fig. 1 .
  • Fig. 3 is a front view showing a first car of Fig. 1 .
  • Fig. 4 is a lateral view showing the first car of Fig. 3 .
  • Fig. 5 is a lateral view showing a state in which a second car chamber of Fig. 4 has moved to a second position.
  • a pair of first guide rails 9a and 9b for guiding the raising/lowering of the first car 7 and a pair of second guide rails 10a and 10b for guiding the raising/lowering of the second car 8 are installed within the hoistway 1.
  • the first landing doorway 11a is disposed facing a front surface of the first car 7 and a back surface of the second car 8.
  • the second landing doorway 12a is disposed facing a front surface of the second car 8 and a back surface of the first car 7.
  • the first car 7 has a first car frame 13 to which the main ropes 6 are connected, and a first car chamber 14 and a second car chamber 15 (front car chamber and rear car chamber), which are supported by the first car frame 13 and can accommodate passengers, respectively.
  • the first car chamber 14 and the second car chamber 15 are each relatively displaceable to a first position ( Figs. 1 to 4 ) at which the first car chamber 14 and the second car chamber 15 are aligned with each other horizontally, and to a second position ( Fig. 5 ) at which the first car chamber 14 and the second car chamber 15 are aligned with each other vertically.
  • the first car door control portion, the second car door control portion, the first inner door control portion, and the second inner door control portion are controlled by the control device 34.
  • Signals from various sensors are input to the control device 34.
  • the second car 8 having the third car chamber 30 is suspended at the second ends of the main ropes 6, so the transport capacity of the elevator apparatus can be enhanced drastically.
  • twice the transport capacity can be obtained with about 1.5 times the space for a hoistway, in comparison with an elevator having a general structure.
  • first car chamber 14 and the second car chamber 15 are displaced independently of each other.
  • first car chamber and the second car chamber may be displaced in an interlocking manner.
  • Displacement of the first car chamber 14 and the second car chamber 15 may be controlled to be completed before the first car 7 and the second car 8 start running, or to be realized while the first car 7 and the second car 8 are running.
  • displacement of the first car chamber 14 and the second car chamber 15 may be realized in accordance with a call registration at a landing or within the first car chamber 14 or the second car chamber 15.
  • a determination on the opening/closing of the inner doors 27 and 28 may also be made in accordance with a call registration at a landing or within the first car chamber 14 or the second car chamber 15.
  • the second car 35 is also structured to have the first car chamber 14 and the second car chamber 15. Therefore, about twice the transport capacity can be obtained with substantially the same space for a hoistway as in an elevator having a general structure.
  • Fig. 11 is a lateral view showing an elevator apparatus according to Embodiment 6 of the present invention.
  • a first drive device 52 and a second drive device 53 are installed within the hoistway 1.
  • the first drive device 52 has a first drive device body including a motor and a brake, and a first drive sheave rotated by the first drive device body.
  • the second drive device 53 has a second drive device body including a motor and a brake, and a second drive sheave rotated by the second drive device body.
  • a second car 60 as a third elevating body is connected to first ends of the second main ropes 57.
  • a second counterweight 61 as a fourth elevating body is connected to second ends of the second main ropes 57.
  • the second car 60 and the second counterweight 61 which are suspended within the hoistway 1 according to the 1:1 roping method by the second main ropes 57, are raised/lowered within the hoistway 1 owing to a driving force of the second drive device 53.
  • the second car may be structured to have a single car chamber as is the case with the second car 8 according to Embodiment 1 of the present invention.
  • the second elevating body and the fourth elevating body may not be designed as the counterweights but as cars.
