Abstract: A bi-swing gate lock uses an electric actuator to unlatch the gate on request, and a failsafe mode that automatically unlatches the gate during emergencies or power failures. The traplock uses two swing arms that pivot retractable door stops in and out on either side of a closed gate from a stationary 4? post. Loads trying to force open a locked gate are redirected through polyurethane pads on the sides of the retractable door stops directly to the insides of matching pockets within the post. Such loads can flex the swing arms, but significant loads will not reach the swing arm pivot bearings. Keeping the gate locked requires electric power applied to a lock actuator, and the loss of power automatically unlocks the traplock. Power applied to a retraction actuator pushes out the retractable door stops. A sensor detects when the gate returns to a closed position and the lock actuator can be energized once again.
