Abstract (en)
[origin: US5065845A] A safety apparatus includes a safety device and a centrifugal force speed governor for preventing overspeed conditions of an elevator car in both the downward direction and the upward direction. A bracket attached to the elevator car slidably retains a shaft at right angle to a guide rail attached to an elevator shaft wall. A U-shaped frame is attached to an end of the shaft and rotatably carries a running wheel. A compression spring extends over the shaft between the bracket and the frame to bias the running wheel against the web of the guide rail. On each side of the running wheel, a pair of release levers are rotatably supported to rotate during travel of the car in normal operation. In response to an overspeed condition, the release levers pivot into engagement with a pair of stationary ratchet wheels which are connected with a pair of actuating levers. The ratchet wheels are rotated by the running wheel which movement rotates the actuating levers. The actuating levers each move a release arm and one of the levers is connected to an actuating rod, which in turn is in connected to a release arm of another safety device on the car. The release arms extend into a wedge box of the safety device to actuate wedge-shaped jaws to engage the guide rail. For resetting the safety apparatus, the elevator car is restarted after a safety stop in the opposite direction of travel.
