Abstract
A compact, lightweight latch ( ) especially adapted for use with an emergency deployment oxygen mask container ( ) is provided which is made up of a minimum of parts and which can be delatched in multiple ways. The latch ( ) includes a latch assembly ( ) designed to be mounted in the oxygen mask container box ( ) and a cooperating latch pin ( ) secured to a cover ( ). The assembly ( ) has a primary latch body ( ) supporting a diaphragm ( ), latch member ( ) and shiftable piston ( ); the latch member ( ) includes a plurality of laterally displaceable, hook-shaped locking legs ( ) configured to interfit with latch pin ( ). The piston ( ) is shiftable in opposite axial directions within latch member ( ), and cooperating surfaces on the member ( ) and piston ( ) serve to positively displace the latching legs ( ) in response to piston movement. During pneumatic operation, the piston ( ) is shifted within latch member ( ) under the influence of diaphragm ( ). The latching member ( ), piston ( ) and latch pin ( ) are preferably in substantial axial alignment, and a passageway ( ) in the latch pin ( ) allows use of push or pull rods ( ) for manual delatching.
