Abstract

A latch system that includes a paddle button assembly having a button that is movable between a home position and an actuation position, a first latch assembly that includes a first striker assembly and a first hook assembly, and a first cable that extends between the paddle button assembly and the first latch assembly. Movement of the button from the home position to the actuation position moves the first cable, thereby disengaging the first hook assembly and the first striker assembly.

First claim

What is claimed is:

1. 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 to disengage a latch assembly that includes a hook assembly and a striker assembly,
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, and
wherein movement of the button from the home position to the actuation position disengages the hook assembly and the striker assembly, whereby the bucket moves from the closed position to the open position
wherein the striker assembly includes a striker, wherein the hook assembly includes a rotary member that includes a hook and a closeout member, 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 is enclosed in a housing, wherein the housing includes a striker opening, wherein the closeout member is positioned to close the striker opening when the rotary member is in the second position,
wherein when the bucket is moved from the open the position to the closed position, the striker contacts the closeout member, thereby moving the rotary member from the second position to the first position, engaging the hook with the striker and rotating the closeout member to a position where it is not positioned in the striker opening.

2. The aircraft storage bin of claim 1 wherein the latch system includes a cable that extends between the paddle button assembly and the latch assembly, and wherein movement of the cable causes movement of one of the hook and the striker to disengage the hook assembly and the striker assembly.

3. The aircraft storage bin of claim 2 wherein the button is pivotal between the home position and the actuation position, wherein pivotal movement of the button pushes or pulls the cable, thereby pivoting a trigger arm from an engaged position to a disengaged position and disengaging the hook from the striker.

4. The aircraft storage bin of claim 3 wherein the paddle button assembly includes an indicator that is movable from a first position to a second position when the button is moved from the home position to the actuation position, and wherein the hook maintains the trigger arm in the disengaged position when the rotary member is in the second position, thereby maintaining the indicator in the second position.

5. The aircraft storage bin of claim 1 wherein the rotary member is biased toward the second position.

6. The aircraft storage bin of claim 5 wherein the rotary member includes a catch member that engages a ledge on the trigger arm in the first position and a stop member in the second position.

7. The aircraft storage bin of claim 1 wherein the paddle button assembly includes an indicator that is movable from a first position to a second position when the button is moved from the home position to the actuation position.

8. The aircraft storage bin of claim 1 wherein the rotary member is rotatable about a rotation axis, wherein when the rotatory member is in the second position at least a portion of the closeout member is positioned on one side of the rotation axis and at least a portion of the hook is positioned on the opposite side of the rotation axis.

9. The aircraft storage bin of claim 1 wherein the closeout member includes a curved surface leading into a mouth of the hook, and wherein when the rotatory member rotates from the second position to the first position the striker slides on the curved surface.

10. The aircraft storage bin of claim 9 wherein the curved surface is convex.

11. A 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 and 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, wherein the rotary member is enclosed in a housing and includes a closeout member, wherein the housing includes a striker opening defined in a top wall thereof, and wherein the closeout member is positioned to close the striker opening when the rotary member is in 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 moves the cable, thereby disengaging the hook assembly and the striker assembly.

12. The latch system of claim 11 wherein movement of the button from the home position to the actuation position pivots a cam member that pushes or pulls the cable.

13. The latch system of claim 11 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.

14. The latch system of claim 13 wherein pivotal movement of the button pushes or pulls the cable, thereby pivoting a trigger arm from an engaged position to a disengaged position and disengaging the hook from the striker.

15. The latch system of claim 14 wherein the paddle button assembly includes an indicator that is movable from a first position to a second position when the button is moved from the home position to the actuation position, and wherein the hook maintains the trigger arm in the disengaged position when the rotary member is in the second position, thereby maintaining the indicator in the second position.

16. The latch system of claim 11 wherein the rotary member is biased toward the second position.

17. The latch system of claim 16 wherein the rotary member includes a catch member that engages a ledge on the trigger arm in the first position and a stop member in the second position.

18. The latch system of claim 11 wherein the paddle button assembly includes an indicator that is movable from a first position to a second position when the button is moved from the home position to the actuation position.

19. The latch system of claim 11 wherein the cam member includes a button engaging end and a cable engaging end, and wherein movement of the button from the home position to the actuation position pivots the cam member thereby pushing or pulling the cable.

20. A method of opening a storage bin, the method comprising the steps of:
moving a button from a home position to an actuation position, wherein movement of the button from the home position to the actuation position moves a cable, thereby disengaging a hook assembly and a striker assembly, wherein a bucket moves from a closed position to an open position, wherein the hook assembly includes a hook and the striker assembly includes a striker, wherein the hook assembly includes a rotary member that includes the hook, where
