ABSTRACT:
An automatic gate opener lock. The gate opener lock has a locking bolt which is moved between locked and unlocked positions by the movement of swing arm of an automatic gate opener. To prevent movement of the locking bolt toward its locked position before the gate is closed, springs are arranged for resisting movement in that direction. The springs have a combined resistive force greater than the force required to move the gate. Only when the gate is closed, and the force from the swing arm may no longer be dissipated through gate movement, is the combined force of the springs overcome, and the locking bolt moved into the locked position.
