Abstract
This elevator car includes: a car frame having a pair of vertical frames and a lower frame linking lower ends of the pair of vertical frames; a floor support beam supporting a car floor and supported on the lower frame; an under-car pulley disposed below the car floor; a pulley support member fixed to the floor support beam and rotatably supporting the under-car pulley; and a linking member linking the vertical frames and the floor support beam. The elevator car has a structure in which an upward force exerted on the pulley support member and the floor support beam by a main rope that is wound around the under-car pulley is received by the linking member and the vertical frames.
Claims8
An elevator car comprising:
- a car frame having a pair of vertical frames and a lower frame directly connected to lower ends of the pair of vertical frames;
- a floor support beam supporting a car floor and supported on the lower frame;
- an under-car pulley disposed below the car floor;
- a pulley support member fixed to the floor support beam and supporting the under-car pulley;
- and
- a linking member linking the vertical frames and the floor support beam,
- wherein the elevator car is configured such that an upward force exerted on the pulley support member and the floor support beam by a main rope that is wound around the under-car pulley is received by the linking member and the vertical frames, and
- wherein the linking member is disposed immediately above the under-car pulley such that the linking member and the under-car pulley overlap each other along a front-to-back direction of the elevator car, and such that the upward force acts on the linking member directly without going through the floor support beam and acts from the linking member to the vertical frames.
An elevator comprising
- an elevator car moving up and down in a hoistway,
- the elevator car including:
- a car frame having a pair of vertical frames and a lower frame directly connected to lower ends of the pair of vertical frames;
- a floor support beam supporting a car floor and supported on the lower frame;
- an under-car pulley disposed below the car floor;
- a pulley support member fixed to the floor support beam and rotatably supporting the under-car pulley;
- and
- a linking member linking the vertical frames and the floor support beam,
- wherein the elevator car is configured such that an upward force exerted on the pulley support member and the floor support beam by a main rope that is wound around the under-car pulley is received by the linking member and the vertical frames, and
- wherein the linking member is disposed immediately above the under-car pulley such that the linking member and the under-car pulley overlap each other along a front-to-back direction of the elevator car, and such that the upward force acts on the linking member directly without going through the floor support beam and acts from the linking member to the vertical frames.
