ABSTRACT:
A luggage latch for securing together two relatively movable parts has a latch housing on one of the parts, a latch component on the other of the parts engageable in the latch housing, and a keeper displaceable in the latch housing between a retaining position engaging and retaining the latch component and a freeing position out of engagement with the latch component and permitting same to be withdrawn from the housing. A combination lock on the housing has combination-lock elements operatively engageable with the keeper and movable between a locked position and an unlocked position respectively corresponding to the retaining and freeing positions of the keeper. In addition a key lock on the housing has a key-lock element operatively engageable with the keeper and movable between a locked position and an unlocked position respectively corresponding to the retaining and freeing position of the keeper. Either of the locks is capable of moving the keeper from the retaining to the freeing position regardless of the position of the other lock. The retaining position of the keeper is a central position and the keeper can move in opposite directions into two end freeing positions. The combination lock allows the keeper to move into one freeing position when it is unlocked and the key lock moves it into the other freeing position when it is unlocked.
