Abstract

A latch system that includes a paddle button assembly having a button that is movable between home and actuation positions, a latch assembly that includes a striker assembly with a striker and a hook assembly, and a cable that extends between the paddle button and latch assembly. The hook assembly includes a hook, a pivotal trigger arm, and a manual override switch that is movable between first and second positions when the trigger arm is moved from an engaged position to a disengaged position. Movement of the button from the home position to the actuation position pushes or pulls the cable, thereby pivoting the trigger arm from the engaged to the disengaged position and disengaging the hook from the striker. Pivotal movement of the trigger arm from the engaged to the disengaged position results in linear movement of the manual override switch from the first to the second position.

First claim

What is claimed is:

1. An aircraft storage bin latch system comprising:
a paddle button assembly that includes a button that is movable between a home position and an actuation position,
a latch assembly that includes a striker assembly and a hook assembly, wherein the hook assembly includes a hook, a trigger arm pivotal from an engaged position to a disengaged position, and a manual override switch that is movable linearly from a first position to a second position when the trigger arm is moved from the engaged position to the disengaged position, wherein the striker assembly includes a striker, wherein the hook assembly includes a rotary member that includes the hook, wherein the rotary member is movable between a first position where the hook is engaged with the striker and a second position where the hook is not engaged with the striker, and wherein the rotary member is biased toward the second position, and
a cable that extends between the paddle button assembly and the latch assembly, wherein movement of the button from the home position to the actuation position pushes or pulls the cable, thereby pivoting the trigger arm from the engaged position to the disengaged position and disengaging the hook from the striker, wherein pivotal movement of the trigger arm from the engaged position to the disengaged position results in linear movement of the manual override switch from the first position to the second position.

2. The aircraft storage bin latch system of claim 1 wherein the button is pivotal between the home position and the actuation position, and wherein the pivoting of the button pushes or pulls the cable, thereby disengaging the hook assembly and the striker assembly.

3. The aircraft storage bin latch system of claim 1 wherein the rotary member includes a catch member that engages a ledge on the trigger arm when the rotary member is in the first position.

4. The aircraft storage bin latch system of claim 1 wherein the rotary member is enclosed in a housing that includes a top wall, wherein the rotary member includes a closeout member, wherein the housing includes a striker opening defined in the top wall of the housing, and wherein the closeout member is positioned to block the striker opening when the rotary member is in the second position.

5. The aircraft storage bin latch system of claim 1 wherein the hook assembly is enclosed in a housing, wherein the manual override switch is at least partially positioned in an opening defined in and exposed to an exterior of the housing, and wherein the manual override switch is movable between the first position and the second position within the opening in the housing.

6. The aircraft storage bin latch system of claim 5 wherein the manual override switch has an outer surface and the housing has an outer side surface, and wherein the outer surface of the manual override switch is substantially flush with the outer side surface of the housing.

7. The aircraft storage bin latch system of claim 1 wherein the button is pivotal between the home position and the actuation position, wherein the paddle button assembly includes a cam member, and wherein pivoting of the button pivots the cam member and pushes or pulls the cable, thereby disengaging the hook from the striker.

8. The aircraft storage bin latch system of claim 7 wherein the cam member includes a cam post extending outwardly that engages a cam surface on the button, and wherein the cam post moves along the cam surface when the button pivots from the home position to the actuation position.

9. An aircraft storage bin that comprises:
an upper housing that includes first and second side panels,
a bucket that cooperates with the upper housing to define a bin interior, wherein the bucket is movable with respect to the upper housing between an open position and a closed position, wherein the bucket includes a bottom and first and second side walls, and
a latch system that includes a paddle button assembly having a button that is movable between a home position and an actuation position, a latch assembly that includes a hook assembly and a striker assembly, and a cable that extends between the paddle button assembly and the latch assembly, wherein the hook assembly includes a hook, a trigger arm pivotal from an engaged position to a disengaged position, and a manual override switch that is movable in a linear direction from a first position to a second position, and wherein the striker assembly includes a striker, wherein the hook assembly includes a rotary member that includes the hook, wherein the rotary member is movable between a first position where the hook is engaged with the striker and a second position where the hook is not engaged with the striker, and wherein the rotary member is biased toward the second position,
wherein the paddle button assembly is associated with one of the bucket and the upper housing,
wherein the hook assembly is associated with one of the bucket and the upper housing and the striker assembly is associated with the other of the bucket and the upper housing,
wherein movement of the button from the home position to the actuation position moves the cable and pivots the trigger arm, thereby disengaging the hook assembly and the striker assembly, whereby the bucket moves from the closed position to the open position, and
wherein linear movement of the manual override switch from the first position to the second position pivots the trigger arm, thereby disengaging the hook assembly and the striker assembly.

10. The aircraft storage bin of claim 9 wherein the rotary member includes a catch member that engages a ledge on the trigger arm when the rotary member is in the first position and a stop member when the rotary member is in the second position.

11. The aircraft storage bin of claim 9 wherein the rotary member is enclosed in a housing that includes a top wall, wherein the rotary member includes a closeout member, wherein the housing includes a striker opening defined in the top wall of the housing, and wherein the closeout member is positioned to block the striker opening when the rotary catch is in the second position.

12. The latch system of claim 9 wherein the button is pivotal between the home position and the actuation position, wherein the paddle button assembly includes a cam member, and wherein pivoting of the button pivots the cam member and pushes or pulls the cable, thereby disengaging the hook from the striker.

13. The latch system of claim 12 wherein the cam member includes a cam post extending outwardly that engages a cam surface on the button, and wherein the cam post moves along the cam surface when the button pivots from the home position to the actuation position.

14. The latch system of claim 9 wherein the hook assembly includes a rotary member that includes the hook, wherein the rotary member is movable between a first position where the hook is engaged with the striker and a second position where the hook is not engaged with the striker, wherein the rotary member includes a closeout member, and wherein the closeout member is positioned to block a striker opening when the rotary member is in the second position.
