Abstract

Official abstract text for this publication.

This invention is concerning a car suspending pulley device including a pair of beams provided parallel to each other on a lower portion of a car and a car suspending pulley arranged between the pair of beams and supported by the pair of beams. A weight suspending pulley is provided on a counterweight. The car and the counterweight are suspended from a main rope wrapped around the car suspending pulley and the weight suspending pulley. A compensating member is suspended between the beams and the counterweight. The compensating member includes a funicular body having a first end portion connected to only one of the pair of beams and a second end portion connected to the counterweight. The first end portion of the funicular body is located in a region of the one beam when viewed in a vertical direction.

First claim

Opening claim text (preview).

The invention claimed is: 1. An elevator comprising: a car; a counterweight; a car suspending pulley device including a pair of beams provided parallel to each other on a lower portion of the car and a car suspending pulley arranged between the pair of beams and supported by the pair of beams; a weight suspending pulley provided on the counterweight; a main rope wrapped around the car suspending pulley and the weight suspending pulley and suspending the car and the counterweight; and a compensating member including a funicular body having a first end portion connected to only one of the pair of beams and a second end portion connected to the counterweight, and suspended between the one beam and the counterweight, wherein the first end portion is located in a region of the one beam when viewed in a vertical direction. 2. The elevator according to claim 1 , wherein when viewed in the vertical direction, a straight line that overlaps the funicular body is inclined with respect to a straight line following a longitudinal direction of the pair of beams. 3. The elevator according to claim 2 , wherein the funicular body is a chain; a first connecting tool is fixed to the one beam; a second connecting tool is fixed to the counterweight; the first end portion of the chain is connected to the one beam by being attached to the first connecting tool and the second end portion of the chain is connected to the counterweight by being attached to the second connecting tool; the first connecting tool is arranged in one of a state of following a straight line that overlaps the chain and a state of being perpendicular to the straight line that overlaps the chain when viewed in the vertical direction; and the second connecting tool is arranged in one of a state of following the straight line that overlaps the chain and a state of being perpendicular to the straight line that overlaps the chain when viewed in the vertical direction. 4. The elevator according to claim 1 , wherein the funicular body is a chain; a first connecting tool is fixed to the one beam; a second connecting tool is fixed to the counterweight; the first end portion of the chain is connected to the one beam by being attached to the first connecting tool and the second end portion of the chain is connected to the counterweight by being attached to the second connecting tool; the first connecting tool is arranged in one of a state of following a straight line that overlaps the chain and a state of being perpendicular to the straight line that overlaps the chain when viewed in the vertical direction; and the second connecting tool is arranged in one of a state of following the straight line that overlaps the chain and a state of being perpendicular to the straight line that overlaps the chain when viewed in the vertical direction.
