Abstract
The locking bolt of a swing bolt lock has an elongated opening that fits on a shaft in the lock's housing. The shaft has a compression spring that biases the bolt toward one side of the shaft. In normal operation, the compression spring urges the bolt such that the shaft is at one end of the elongated opening. There, the swing bolt pivots about the shaft to unlock the lock. When a person tries to force the lock, the elongated opening of the bolt moves against spring bias along the shaft. In one embodiment, flat surfaces in the opening and on the shaft engage each other and a notch on the outside surface of the bolt engages a stationary safety key. This prevents the bolt from applying sufficient force to break weaker parts within the lock mechanism and force the lock open.
