Abstract

A control cable guide device for an elevator, which is to be mounted to a control cable suspended between a middle portion of a hoistway and a lower portion of a car, the control cable having a curved portion formed at a lower end position of the control cable, the control cable guide device including an arm to be suspended on the control cable at a position below the car in a pivotable manner. The arm is configured to be pushed upward by the curved portion when the car is caused to travel to a lowermost position within a normal traveling range, to thereby shift to a cable receiving position for receiving the control cable while being partially projected from the car in a horizontal direction.

First claim

The invention claimed is:

1. A control cable guide device for an elevator, which is to be mounted to a control cable, the control cable extending from a middle portion of a hoistway, along a cable suspending side surface of a car, and to a lower portion of the car, the control cable having a curved portion formed at a lower end position of the control cable, the control cable guide device comprising:
an arm to be suspended on the control cable at a position below the car in a pivotable manner, the arm being configured to be pushed upward by the curved portion when the car is caused to travel to a lowermost position within a normal traveling range, to thereby shift to a cable receiving position for receiving the control cable,
wherein when the arm is in the cable receiving position, the arm projects to the cable suspending side beyond a plane formed by the side surface of the car as viewed from a top of the car.

2. The control cable guide device for an elevator according to claim 1 , further comprising a branch member projected from the arm, for pivoting the arm while being guided along the curved portion,
wherein, when the car is caused to travel to the lowermost position, the arm is pushed upward by the curved portion while the branch member is being guided along the curved portion, to thereby shift to the cable receiving position.

3. The control cable guide device for an elevator according to claim 1 , further comprising a magnet provided to the control cable, for retaining the arm with a magnetic attraction force when the car is located at the lowermost position, to thereby maintain a position of the arm at the cable receiving position.

4. The control cable guide device for an elevator according to claim 3 , wherein the arm comprises a cable regulating unit for regulating a shift of the control cable in a direction away from a cable receiving-side end portion, which is a part of the arm for receiving the control cable.

5. The control cable guide device for an elevator according to claim 1 , further comprising a link member suspended on the control cable in a pivotable manner, the link member having a slit along which the arm is slidable,
wherein, when the car is located at the lowermost position, the link member receives the arm with a spring arranged inside the slit, to thereby maintain the position of the arm at the cable receiving position.

6. The control cable guide device for an elevator according to claim 1 , wherein the arm comprises a cable regulating unit for regulating a shift of the control cable in a direction away from a cable receiving-side end portion, which is a part of the arm for receiving the control cable.
