Abstract
An aircraft latch is disclosed for latching to the preexisting latch pin of an aircraft assembly. The latch includes a trigger safety to block the trigger from accidentally being opened. A link trunion adds rigidity to the system and cooperates with the trigger safety to provide an anti-vibrating feature. A detent on the latch cooperates with the installation housing in which the latch pin is mounted to hold the latch handle in place when the latch is fully opened to prevent the aircraft doors in which the latch is mounted from being closed inadvertently while the latch is still unlatched.
Claims18
An aircraft latch having a slotted housing mounted thereon comprising:
- a) a hook assembly having a main body portion terminating at one end in a hook adapted to engage a trigger assembly having a latching pin and a trigger-locking pin remote from said hook;
- b) a trunion plate pivotally mounted on said body portion engaging said housing, said trigger assembly having a spring-biased trigger pivotally mounted thereon having notches therein for engaging said trigger-locking pin, said trigger movable from a first position out of engagement with said trigger-locking pin to a second position in engagement with said trigger-locking pin, said trigger assembly having a spring-biased trigger-release pin normally disposed in a position away from engagement with said trigger;
- and
- c) a pivotable handle having a first end pivotably secured to a handle portion integral with said trigger assembly having a spring-biased locking sleeve mounted thereon normally locking said handle in a first position extending normal to the longitudinal axis of said trigger assembly and said sleeve, which, when released from its spring-bias, enables said handle to move to a second position generally parallel to the longitudinal axis of said trigger assembly, said handle having an abutment flange thereon engaging said spring-biased trigger release pin holding the same against said trigger when said handle is in the second position.

An aircraft latch comprising:
- a) a housing;
- b) a hook assembly having a main body portion terminating at one end in a hook adapted to engage a trigger assembly on said housing, and a trigger-locking pin on said housing remote from said hook;
- c) a trunion plate pivotally mounted on said main body portion, said trigger assembly having a spring-biased trigger pivotally mounted thereon having notches therein for engaging said trigger-locking pin, said trigger movable from a first position out of engagement with said trigger-locking pin to a second position in engagement with said trigger-locking pin, said trigger assembly having a spring-biased trigger-release pin normally disposed in a position away from engagement with said trigger;
- and
- d) a pivotable handle having a first end pivotably secured to a handle portion integral with said trigger assembly having a spring-biased locking sleeve mounted thereon normally locking said handle in a first position extending normal to the longitudinal axis of said trigger assembly and said sleeve, which, when released from its spring-bias, enables said handle to move to a second position generally parallel to the longitudinal axis of said trigger assembly, said handle having an abutment flange thereon engaging said spring-biased trigger release pin holding the same against said trigger when said handle is in the second position.
