A lock in which a closure structure carries a cammable latch bolt which is spring urged toward a latching position. Stops are provided on the latch bolt and on a member carrying the latch bolt to normally prevent retracting movement of the latch bolt under inertia forces. The latch bolt is mounted for movement in a direction to displace the stops out of a registering position to permit camming of the latch bolt toward a releasing position during closing movement of the closing structure.
