Magnetically-triggered lock mechanism

A magnetically-triggered lock mechanism for interengaging two relatively movable components, comprising a bolt displaceable between extended and retracted positions, the bolt mounted within a first component and interengageable with a second component when the first and second components are in a predetermined position relative to each other and the bolt is extended. The lock mechanism includes a magnetically-releasable latch mechanism positioned to latch the bolt in a retracted position, the latch mechanism including a first magnet and mounted for movement between a biased latch engaging position and a latch releasing position, and a second magnet positioned to displace the latch mechanism to the latch releasing position when the components are in the predetermined position relative to each other. The magnets are positioned to displace the latch mechanism to the latch releasing position as a result of magnetic repulsion when the components are in the predetermined position relative to each other.
