car return sheave 17 is disposed such that themain ropes 12 extend parallel to the frontage direction of the car 4 (to the left and right in Figure 1) between thecar return sheave 17 and thedrive sheave 11, changes in frontage dimensions of thecar 4 can be adapted to easily. in addition, changes in depth dimensions of thecar 4 can also be adapted to easily, simply by adjusting the angle of thecounterweight return sheave 18. Consequently, installation work is facilitated, and standardization of equipment is enabled. - In addition, since the
main ropes 12 are composed of a synthetic fiber rope having a high coefficient of friction and superior flexibility, diameters of thedrive sheave 11 and thereturn sheaves hoistway 1 is utilized even more efficiently, enabling height dimensions of thehoistway 1 to be kept small. - Furthermore, since the
driving machine 9 is disposed horizontally such that that thedrive sheave 11 is on top, maintenance work on thedriving machine body 10 such as on the brake, etc., can be performed easily from on top of thecar 4, enabling workability to be improved. Height dimensions required for installing thedriving machine 9 and thereturn sheaves - Furthermore, by using the
rubber vibration isolators 8 on themounting frame 6, noise due to vibration of thedriving machine 9 and thereturn sheaves guide rails - Figure 5 is a general plan showing an elevator apparatus according to
Embodiment 2 of the present invention, and Figure 6 is a partial cross section taken along line VI - VI in Figure 5. In the figures, thecounterweight 5 is disposed beside thecar 4. Accompanying this, thecounterweight return sheave 18 is disposed above a side portion of thecar 4. Furthermore, thecounterweight return sheave 18 is disposed such that an axis thereof extends parallel to an axis of thecar return sheave 17. Hence, themain ropes 12 are disposed such that portions extending from thedrive sheave 11 to thecounterweight return sheave 18 are parallel to portions extending from thedrive sheave 11 to thecar return sheave 17. The rest of the construction is similar to that ofEmbodiment 1. - Using an elevator apparatus of this kind, space inside the
hoistway 1 is also utilized efficiently, enabling height dimensions of thehoistway 1 to be kept small. Changes in depth dimensions of thecar 4 can also be adapted to easily. Consequently, installation work is facilitated, and standardization of equipment is enabled. - Figure 7 is a general plan showing an elevator apparatus according to
Embodiment 3 of the present invention, Figure 8 is a partial cross section taken along line VIII - VIII in Figure 7, and Figure 9 is a partial cross section taken along line IX - IX in Figure 7. - In the figures, the
counterweight 5 is disposed behind thecar 4. Arotatable deflection sheave 31 is disposed in an upper portion inside thehoistway 1. Themain ropes 12 are wound around thedeflection sheave 31 between thedrive sheave 11 and thecounterweight return sheave 18. Thedeflection sheave 31 is disposed such that an axis thereof extends in a vertical direction. Themain ropes 12 are disposed such that portions extending from thedrive sheave 11 to thedeflection sheave 31 are parallel to portions extending from thedrive sheave 11 to thecar return sheave 17. The rest of the construction is similar to that ofEmbodiment 1. - Using an elevator apparatus of this kind, space inside the
hoistway 1 is also utilized efficiently, enabling height dimensions of thehoistway 1 to be kept small. Changes in depth dimensions of thecar 4 can also be adapted to easily, simply by adjusting dimensions of the mountingframe 6. In other words, the layout can be standardized for an elevator apparatus in which thecounterweight 5 is disposed behind thecar 4, irrespective of the dimensions of thecar 4. Consequently, installation work is facilitated, and standardization of equipment is enabled. - In addition, by disposing the
deflection sheave 31 between thedrive sheave 11 and thecounterweight return sheave 18, the contact angle of themain ropes 12 onto thedrive sheave 11 can be kept uniform irrespective of the dimensions of thecar 4. - Moreover, in elevator apparatuses having the layouts shown in
Embodiments 1 to 3, it is also possible to use main ropes composed of a steel rope, but space saving is effectively enabled by using main ropes composed of a synthetic fiber rope such as that described above, making the synthetic fiber rope particularly suitable.
