Abstract

There is provided herein an aircraft galley container including a door, a latch mechanism, and a lock. The latch mechanism is positionable in a latched position preventing opening of the door and an unlatched position permitting opening of the door. The latch mechanism includes a handle, a pair of rods and a rotatable plate. The rotatable plate is coupled to the handle and configured to be rotated by the handle and to convert rotational movement of the handle to linear movement of the pair of rods to place the latch mechanism in the latched and unlatched positions. The lock is configured to selectively prevent the rotatable plate from rotation to maintain the latch mechanism in the latched position.

First claim

What is claimed is:

1. An aircraft galley container comprising:
a door;
a latch mechanism, wherein the latch mechanism is positionable in a latched position preventing opening of the door and an unlatched position permitting opening of the door, wherein the latch mechanism includes:
a handle;
a pair of rods; and
a rotatable plate coupled to the handle and configured to be rotated by the handle and to convert rotational movement of the handle to linear movement of the pair of rods to place the latch mechanism in the latched and unlatched positions; and

a lock configured to selectively prevent the rotatable plate from rotation to maintain the latch mechanism in the latched position,
wherein the lock includes a rotatable locking member rotatable between a locking position and an open position, and
wherein the rotatable plate includes a recess, wherein the rotatable locking member is disposed within the recess when in the locking position and is displaced from the recess when in the open position.

2. The aircraft galley container of claim 1 , wherein the aircraft galley container is a refrigerator.

3. The aircraft galley container of claim 1 , wherein the locking position is disposed at 90° from the open position.

4. The aircraft galley container of claim 1 , wherein the recess is a slot disposed between front and back surfaces of the rotatable plate.

5. The aircraft galley container of claim 1 , wherein the recess is a through hole.

6. The aircraft galley container of claim 1 , wherein the rotatable locking member is configured to abut a side edge of the rotatable plate when in the locking position.

7. The aircraft galley container of claim 1 , wherein the lock is configured to be operated manually by use of a key.

8. The aircraft galley container of claim 1 , wherein the lock is configured to be remotely operated.

9. The aircraft galley container of claim 1 , wherein the lock is replaceably removable from the aircraft galley container.

10. The aircraft galley container of claim 9 , wherein the lock comprises a lock housing and one or more fasteners disposed to attach the lock housing to the door.

11. The aircraft galley container of claim 10 , wherein the door comprises a front panel including an aperture in which the lock housing is located and wherein the one or more fasteners are disposed behind the front panel.

12. A system comprising:
a plurality of aircraft galley containers such as the aircraft galley container of claim 8 ;
a control module configured to display a lock status of each of the plurality of aircraft galley containers and to receive inputs from a user to selectively lock or unlock the lock of each aircraft galley container; and
a processor configured to detect the lock status of each of the plurality of aircraft galley containers for display on the control module and configured to lock or unlock the lock of each aircraft galley container in response to the inputs from the user.
