  • the twomain rope engagement grooves 12a formed in the outer peripheral surface of the drive sheave 12 are grooves of a U-shaped sectional configuration having a groove width approximate to the diameter of the main ropes 30 and 31, thus increasing the contact area between the main ropes 30, 31 and the drive sheave 12 to reduce the contact pressure.
  • the first main rope 30 is wrapped around the drive sheave 12 such that two lead-out portions 30a and 30b extending in different directions from the drive sheave 12 cross each other at a predetermined position.
  • the driving machine 9 is installed such that the rotation axis of the drive sheave 12 is inclined with respect to the vertical line by an acute angle (2.5 degrees).
  • the first deflector sheave 17 guiding the first main rope 30 from the driving machine 9 to the car 4 and the second deflector sheave 18 guiding the first main rope 30 from the driving machine 9 to the counterweight 5.

  • the elevator apparatus of this embodiment can be constructed at low cost by using the general-purpose main ropes 30 and 31 and, further, can elongate the service life of the main ropes 30 and 31.
  • the driving machine 9 since the driving machine 9 has a thin and flat external configuration whose axial length is smaller than the outer diameter thereof, it is possible to reduce the vertical dimension of the hoistway 1.
  • main rope engagement grooves 12 formed in the outer peripheral surface of the driving machine 9 and adapted to be engaged with the main ropes 30 and 31 have a U-shaped sectional configuration.
  • the car 4 is suspended with the main ropes 30 and 31 being connected to the lower portion of the car 4.
  • the car 4 is suspended with the main ropes 30 and 31 being connected to the lower beam end portions 4a and 4b, so that the length of the suspension portions 20a and 20b composed of the rope shackles 13a and 13b extending upwardly from the lower beam end portions 4a and 4b and the buffer members 14a and 14b is balanced by the vertical length of the car 4, whereby the vertical dimension of the entire car 4 can be made smaller than in the prior art, and, by extension, it is possible to reduce the vertical dimension of the hoistway 1.
  • first, second, and third deflector sheaves 17, 18, and 19 are installed such that their respective rotation axes are horizontal and that they overlap the car 4 or the counterweight 5 in a vertical plane of projection, so that it is possible to reduce the cross-sectional area of the hoistway 1, thus realizing a small-space elevator apparatus.
  • the driving machine 9, the speed governor 33, the return wheel 10, the first, second, and third deflector sheaves 17, 18, and 19, and the control panel 32 are mounted to the support stage 8 provided in the upper portion in the hoistway 1, and the driving machine 9, the speed governor 33, the return wheel 10, and the control panel 32 are installed within the range (indicated by symbol D) as defined by the vertical dimension of the first, second, and third deflector sheaves 17, 18, and 19 and between the rope groove 12a of the drive sheave 9 on the opposite side of the motor and the end surface of the drive sheave 12 on the opposite side of the motor.
  • the range indicated by symbol D
  • the support stage 8 is supported at the upper ends of the guide rails 2.
  • the support structure can be easily constructed, making it possible to realize an inexpensive elevator apparatus.
  • the support stage 8 is supported by the guide rails 2 through the intermediation of vibration-proof members 34.

  • the arc of contact of the main ropes 30 and 31 with respect to the drive sheave 12 is increased as compared with that in the prior art, and, further, the drive sheave 12 is provided with main rope engagement grooves with a U-shaped sectional configuration to thereby increase the contact area, whereby, in contrast to the prior art, there is no need to use an expensive, high-friction main rope or to provide a drive sheave with a main rope engagement groove of a special configuration into which such a high friction main rope is forced to achieve an increase in traction, making it possible to ensure a predetermined traction with a general-purpose main rope and, further, to elongate the service life of the main ropes 30 and 31.
  • two main ropes of the first and second main ropes 30 and 31 are used as the main ropes; this is mainly for the purpose of connecting the main ropes to the bottom portion of the car 4. That is, in this embodiment, a single main rope suffices if the suspension of the car is to be effected with the main rope connected to the top portion of the car 4, and either of the main ropes may be omitted.
  • the first and second main ropes 30 and 31 are wrapped around the drive sheave 12 at an arc of contact of approximately 255 degrees; this is due to the fact that the hoisting machine 9 is arranged at a position farthest apart from the deflector sheaves 17 through 19 in order to minimize the angular error with which the main ropes 30 and 31 paid out from the sheave grooves 12a are engaged with the grooves of the deflector sheaves 17 through 19.
  • the inclination angle of the driving machine 9 and the return wheel 10 with respect to the vertical line is 2.5 degrees; if the inclination angle is larger than this, it is highly possible that the main ropes 30 and 31 will be detached or that the corners of the sheave grooves 12a will come into contact with the main ropes when the main ropes 30 and 31 are attached with/detached from the sheave grooves 12a, resulting in the main ropes 30 and 31 and the rope grooves 12a being damaged.
  • the driving machine 9 is arranged above a corner of the car 4, so that it is possible to ensure, between the driving machine 9 and the first, second, and third direction changing deflector sheaves 17, 18, and 19, a sufficient distance for twisting the main ropes 30 and 31, and, at the same time, it is possible to ensure a sufficient arc of contact with respect to the drive sheave 12.
  • Fig. 7 is a plan view of a machine-room-less type elevator apparatus according to Embodiment 2 of the present invention.
  • the counterweight 5 is arranged by the side of, that is, laterally to, the car 4 in the hoistway 1, whereas, in this embodiment, the counterweight 5 is by the side of the car 4 in the hoistway 1, as shown in Fig. 7 . Otherwise, this embodiment is of the same construction as Embodiment 1.
  • the present invention is also applicable to an elevator apparatus thus constructed; in this embodiment, the counterweight 5 is arranged on the opposite side of the first deflector sheave 17 and the return wheel 10 with respect to the car 4, so that it is possible for the arc of contact to be larger than that in the apparatus of Embodiment 1.
  • the driving machine 9 and the first, second, and third direction changing deflector sheaves 17, 18, and 19 are mounted at the upper end of the guide rails 2 by means of the support stage 8, it is also possible for the driving machine and the direction changing deflector sheaves to be directly supported by the ceiling of the hoistway 1 or the building. Alternatively, the support stage 8 may be directly supported by the ceiling of the hoistway 1 or the building.
  • the present invention is most suitable for an elevator to be installed in a small space. Further, it is most suitable for an elevator that is required to be inexpensive and easy to maintain.
