Abstract

An aircraft trolley retention device may include a retention latch with a shaft including a first component of an interlocking assembly and a sleeve including a second component of the interlocking assembly and configured to receive the shaft, and an interlocking assembly. The retention latch may be configured to actuate between a closed position and an open position. The interlocking assembly may be configured to guide the retention latch during the actuation between the closed position and the open position. The retention latch may be configured to retain an aircraft trolley within an aircraft trolley bay when the retention latch is in the closed position. A portion of the retention latch may be configured to be positioned in front of a striker plate corresponding to a handle of an aircraft trolley bay door of the aircraft trolley bay when the retention latch is in the open position.

First claim

What is claimed is:

1. An aircraft trolley retention device, comprising:
a retention latch, the retention latch including a shaft;
a sleeve, the sleeve being configured to receive the shaft, the sleeve being configured to be coupled to an aircraft trolley bay of an aircraft monument;
an interlocking assembly, the shaft including a first component of the interlocking assembly, the sleeve including a second component of the interlocking assembly,
the retention latch being configured to actuate between a closed position and an open position following an application of a force to the retention latch,
the first component and the second component of the interlocking assembly being configured to guide the retention latch during the actuation between the closed position and the open position,
the retention latch being configured to retain an aircraft trolley within the aircraft trolley bay when the retention latch is in the closed position,
a portion of the retention latch being configured to be positioned in front of a striker plate corresponding to a handle of an aircraft trolley bay door of the aircraft trolley bay when the retention latch is in the open position; and
a spring disposed within the shaft and between the shaft and the sleeve, the spring being configured to apply the force to the retention latch via the shaft during the actuation between the closed position and the open position,
the first component of the interlocking assembly including a pin, the second component of the interlocking assembly including a track, the pin being configured to actuate within the track following the application of force,
the track comprising a horizontal section between a first end and a corner, wherein the shaft is configured to rotate relative to the sleeve with actuation of the pin between the first end and the corner.

2. The retention device of claim 1 , the track comprising:
an angled section between the corner and a second end.

3. The retention device of claim 2 , the pin being configured to actuate from the first end to the second end via the horizontal section, the corner, and the angled section when the retention latch actuates between the closed position and the open position following the application of the force.

4. The retention device of claim 2 , the spring being configured to apply the force to the retention latch during the actuation from the corner to the second end via the angled section when the retention latch actuates between the closed position and the open position.

5. The retention device of claim 1 , wherein the horizontal section is a first horizontal section; the track comprising:
a vertical section between the first corner and a second corner; and
a second horizontal section between the second corner and a second end.

6. The retention device of claim 5 , the pin being configured to actuate from the first end to the second end via the first horizontal section, the first corner, the vertical section, the second corner, and the second horizontal section when the retention latch actuates between the closed position and the open position following the application of the force.

7. The retention device of claim 5 , the spring being configured to apply the force to the retention latch during the actuation from the first corner to the second corner via the vertical section when the retention latch actuates between the closed position and the open position.

8. The retention device of claim 1 , the retention latch being configured to retain the aircraft trolley within the aircraft trolley bay via contact with a surface of an aircraft trolley content door of the aircraft trolley when the retention latch is in the closed position.

9. The retention device of claim 1 , the retention latch being configured to retain the aircraft trolley within the aircraft trolley bay via contact with a surface of a body of the aircraft trolley when the retention latch is in the closed position.

10. The retention device of claim 1 , the retention latch configured to allow the aircraft trolley to be removed or inserted into the aircraft trolley bay when the retention latch is in the open position.

11. The retention device of claim 1 , the portion of the retention latch configured to be separated a selected distance from the striker plate corresponding to the aircraft trolley bay door of the aircraft trolley bar when the retention latch is in the open position.

12. The retention device of claim 11 , the retention latch configured to be in a first plane shared with the striker plate when in the closed position, the retention latch configured to be in a second plane when in the open position, the second plane spaced a selected distance outward from the first plane with respect to the trolley bay such that the retention latch is configured to be separated the selected distance from the striker plate.

13. An aircraft monument, comprising:
an aircraft trolley;
an aircraft trolley bay, the aircraft trolley bay including an aircraft trolley bay door, the aircraft trolley bay including a striker plate corresponding to a handle of the aircraft trolley bay door; and
an aircraft trolley retention device, comprising:
a retention latch, the retention latch including a shaft;
a sleeve, the sleeve being configured to receive the shaft, the sleeve being configured to be coupled to the aircraft trolley bay;
an interlocking assembly, the shaft including a first component of the interlocking assembly, the sleeve including a second component of the interlocking assembly,
the retention latch being configured to actuate between a closed position and an open position following an application of a force to the retention latch,
the first component and the second component of the interlocking assembly being configured to guide the retention latch during the actuation between the closed position and the open position,
the retention latch being configured to retain the aircraft trolley within the aircraft trolley bay when the retention latch is in the closed position,
a portion of the retention latch being configured to be positioned in front of the striker plate when the retention latch is in the open position; and
a spring disposed within the shaft and between the shaft and the sleeve, the spring being configured to apply the force to the retention latch via the shaft during the actuation between the closed position and the open position,
the first component of the interlocking assembly including a pin, the second component of the interlocking assembly including a track, the pin being configured to actuate within the track following the application of force,
the track comprising a horizontal section between a first end and a corner, wherein the shaft is configured to rotate relative to the sleeve with actuation of the pin between the first end and the corner.

14. The aircraft monument of claim 13 , the aircraft trolley comprising an aircraft trolley content door, the retention latch configured to retain the aircraft trolley aircraft trolley content door within the aircraft trolley bay via contact with a surface of the aircraft trolley content door when the retention latch is in the closed position.

15. The aircraft monument of claim 14 , the retention latch configured to allow the aircraft trolley to be removed or inserted into the aircraft trolley bay when the retention latch is in the open position.

16. The aircraft monument of claim 15 , the portion of the retention latch configured to be separated a selected distance from the striker plate corresponding to the aircraft trolley bay door of the aircraft trolley ba
