とができる。[Function] The brake release manual winding device of the present invention uses a manual winding handle mechanism to release the brake through a hoistway enclosure such as a landing wall near the hoisting machine when the car stops between floors due to a power outage or the like. By operating the input member of the rotational force transmission mechanism, the release plate can be caused to release the brake, and when the brake is released, the manual winding handle mechanism can manually rotate the shaft of the hoist via the rotational force transmission mechanism. The car can be rotated to raise and lower the car, allowing maintenance workers to release the brake and manually wind the hoist outside the hoistway without entering the hoistway. Furthermore, if the lower frame of the car interferes with the hand-winding handle mechanism when raising and lowering the car by hand-winding, the handle mechanism may be changed in its operating direction, for example from diagonally upward to diagonally downward. By operating the input member and the release plate, the car can be raised or lowered without causing the handle mechanism to interfere with the car lower frame or the like.

る。[Effect of the Invention 1] As explained above, according to the present invention, the maintenance worker can operate the input member of the rotational force transmission mechanism through the inspection port provided in the enclosure at the bottom of the hoistway using the hand-wound handle mechanism. By doing so, it is possible to cause the release plate to release the brake of the hoisting machine, and when the brake is released, the shaft of the hoisting machine is manually rotated by the manual winding handle mechanism via the rotational force transmission mechanism. Since the car can be raised and lowered, maintenance workers can release the brakes and perform manual hoisting work outside the hoistway without having to enter the hoistway, so if the car stops between floors due to a power outage or malfunction. This makes it easier to rescue passengers inside the car, prevents maintenance workers from being in danger due to the car falling, and furthermore, when raising and lowering the car by hand-wrapping, the lower frame of the car can be easily removed. By displacing the operation direction of the handle mechanism and operating the input member and the operation member, the car can be raised and lowered avoiding obstacles such as the lower frame of the car without interfering with the handle mechanism. Therefore, the effect that the car can be raised and lowered reliably with good workability can be obtained.
