Abstract
A safety device includes a trigger mechanism for triggering a braking wedges attached to first and second double levers to stop an elevator car. A retaining spring detents with a pin on the first double lever and a tension spring engages either the first double lever or the second double lever. The retaining spring maintains the double levers unactuated during normal operation of the elevator and the spring element actuates the double levers after an actuation of the trigger mechanism by a speed limiter.
