- the present invention has been made to solve the problem discussed above, and it is therefore an object of the invention to obtain an elevator apparatus capable of allowing a reduction in the dimension of a hoistway in the height direction thereof.
- An elevator apparatus includes: an elevating body that can be raised/lowered within a hoistway; and a raising/lowering mechanism having a driving device including a driving sheave, a main rope, which is looped around the driving sheave, for suspending the elevating body within the hoistway, a tension pulley, around which the main rope is looped for applying a tensile force to the main rope, for raising/lowering the elevating body by a driving force of the driving device.
- the elevating body is provided with a protrusion portion protruding from a lateral surface portion of the elevating body, and the main rope is connected at one end of the main rope and the other end of the main rope to the protrusion portion.
- Fig. 1 is a front view showing an elevator apparatus according to Embodiment 1 of the present invention.
- Fig. 2 is a lateral view showing the elevator apparatus of Fig. 1.
- a car 2 as an elevating body is disposed within a hoistway 1 such that the car 2 can be raised/lowered therein.
- a pair of car guide rails (not shown) for guiding the car 2 are installed within the hoistway 1.
- the car 2 is raised/lowered within the hoistway 1 while being guided by the car guide rails.
- the car 2 has a floor portion 2a, a ceiling portion 2b disposed above the floor portion 2a, a front surface portion 2c provided with a car doorway 3, a back surface portion 2d opposed to the front surface portion 2c, and a pair of lateral surface portions 2e opposed to each other with respect to a frontage direction of the car doorway 3.
- the car 2 is disposed within the hoistway 1 such that the frontage direction of the car doorway 3 extends parallel to a width direction of the hoistway 1.
- the lateral surface portions 2e are disposed between the car guide rails, respectively. A line connecting the respective car guide rails extends parallel to the width direction of the hoistway 1 when the hoistway 1 is vertically projected.
- a protrusion portion 4 protruding outside the car 2 is provided on an intermediate portion of one of the lateral surface portions 2e.
- the protrusion portion 4 extends horizontally from the car 2.
- the protrusion portion 4 is disposed outside a region of the car 2 on a vertical projection plane of the hoistway 1.
- a driving device (hoisting machine) 5 for generating a driving force for raising/lowering the car 2 is provided in an upper portion of the hoistway 1.
- the driving device 5 has a driving device body 6 including a motor, and a driving sheave 7 rotated by the driving device body 6.
- the driving device 5 is designed as a low-profile hoisting machine having an axial dimension that is smaller than a radial dimension of the driving device body 6 or the driving sheave 7.
- the driving device 5 is disposed such that the axial direction thereof coincides with the width direction of the hoistway 1.
- a plurality of main ropes 8 are looped around the driving sheave 7.
- the car 2 is suspended within the hoistway 1 by means of the respective main ropes 8.
- An outer peripheral portion of each of the main ropes 8 is covered with a material having a high coefficient of friction. Thus, a frictional force between the driving sheave 7 and each of the main ropes 8 is ensured.
- a tension pulley 9 around which the respective main ropes 8 are looped is provided in a lower portion of the hoistway 1.
- the tension pulley 9 can be displaced with respect to the car guide rails.
- the tension pulley 9 is mounted to a rotating member that can rotate vertically with respect to the car guide rails.
- the tension pulley 9 is suspended by the respective main ropes 8.
- the tension pulley 9 thus applies a tensile force to each of the main ropes 8.
- the tension pulley 9 is provided with a weight (not shown) for ensuring a predetermined magnitude of a tensile force to be applied to the main ropes 8.
- the protrusion portion 4 is provided with an upper rope fastening portion 10 for connecting the respective main ropes 8 to the protrusion portion 4 above the protrusion portion 4, and a lower rope fastening portion 11 for connecting the respective main ropes 8 to the protrusion portion 4 below the protrusion portion 4.
- Each of the main ropes 8 has a first connection portion (one end) 8a connected to the upper rope fastening portion 10, and a second connection portion (the other end) 8b connected to the lower rope fastening portion 11.
- Each of the main ropes 8, which extends from the first connection portion 8a to the second connection portion 8b, is sequentially looped around the driving sheave 7 and the tension pulley 9. That is, the elevator apparatus according to Embodiment 1 of the present invention is a counterweight-less elevator apparatus having no counterweight.
- the driving device 5 and the tension pulley 9 are disposed outside the region of the car 2 on a vertical projection plane of the hoistway 1.
- the car 2 can be raised/lowered between an upper-limit position at which the ceiling portion 2b is higher than the position of the driving device 5 and a lower-limit position at which the position of the floor portion 2a is lower than the position of the tension pulley 9.
- a raising/lowering mechanism 12 raising/lowering the car 2 within the hoistway 1 while suspending the car 2 has the driving device 5, the main ropes 8, and the tension pulley 9.
- the raising/lowering mechanism 12 is disposed outside the region of the car 2 on the vertical projection plane of the hoistway 1.
- the car 2 is provided with the protrusion portion 4 protruding from the lateral surface portion 2e of the car 2, and the first connection portion 8a and the second connection portion 8b of each of the main ropes 8 are connected to the protrusion portion 4. Therefore, the positions of the upper rope fastening portion 10 and the lower rope fastening portion 11, for connecting the respective main ropes 8 to the car 2, can be confined within a range of the height dimension of the car 2. Accordingly, spaces above and below the car 2 can be reduced by the height dimensions of the rope fastening portions 10 and 11, respectively. As a result, the dimension of the hoistway 1 in the height direction thereof can be reduced.
- the raising/lowering mechanism 12 is disposed outside the region of the car 2 on the vertical projection plane of the hoistway 1. Therefore, while the car 2 is raised/lowered within the hoistway 1, neither the driving device 5 nor the tension pulley 9 interferes with the car 2 even when a part of the car 2 has reached a height at which the driving device 5 or the tension pulley 9 is installed. Accordingly, the range in which the car 2 can be raised/lowered can be enlarged within the hoistway 1. As a result, the dimension of the hoistway 1 in the height direction thereof can further be reduced.
- the material having the high coefficient of friction is provided on the outer peripheral portion of each of the main ropes 8. Therefore, a frictional force between each of the main ropes 8 and the driving sheave 7 can be ensured. As a result, the main ropes 8 can be prevented from slipping with respect to the driving sheave 7.

- Each of the main ropes 8 is guided from the driving sheave 7 to the first return pulley 21 and the second return pulley 22, so the looping angle of each of the main ropes 8 with respect to the driving sheave 7 is held equal to a predetermined angle.
