Abstract
A shock-activated lock for attachment to a cabinet that prevents the cabinet door from opening in the event of an earthquake. The lock includes a slotted engaging member attached to the cabinet door, and a lock housing attached to the cabinet frame that contains a ball that normally rests on a raised shelf. The engaging member extends into the housing when the door is closed. In the event of an earthquake, the ball falls into the slot in the engaging member, preventing the engaging member from withdrawing from the housing, thus preventing the cabinet door from opening.
