Abstract

A connecting means provides a connecting passage between a first compartment of a vehicle and a storage means located in a second compartment of the vehicle. The first and the second compartment are separated by a wall. A catering system for a vehicle includes the connecting means. A method provides a sealed connecting passage between a first compartment of a vehicle and a storage means located in second compartment of a vehicle. The connecting means includes a frame, a hatch arrangement for selectively closing and opening a frame aperture with a hatch cover and a bellows arrangement including a flexible bellows. The flexible bellows can be extended from the frame to a storage means located in the second compartment of the vehicle. A continuous passage defined by the flexible bellows and the frame provides a sealed connecting passage between the first compartment and the storage means.

First claim

The invention claimed is:

1. An aircraft comprising:
a first compartment;
a second compartment separated by a wall; and
a connecting means for providing a connecting passage between the first compartment and a storage means located in the second compartment, the connecting means comprising:
a frame enclosing a frame aperture and extending in a frame plane;
a hatch arrangement mounted to the frame for selectively closing and opening the frame aperture and comprising at least a first hatch cover, the first hatch cover being movable parallel to the frame plane between an opened position and a closed position;
a bellows arrangement mounted to the frame and comprising a flexible bellows, wherein the flexible bellows and the frame enclose a continuous passage terminating at one end in the frame aperture and wherein the flexible bellows has at least a retracted position and an extended position in a direction transverse to the frame plane; and
wherein the connecting means is arranged in an aperture in the wall between the first and the second compartment such that the frame plane extends parallel to the wall and the hatch arrangement is arranged between the flexible bellows and the first compartment, such that, in the extended position the flexible bellows is extends from the frame to a storage means located in the second compartment, whereby the continuous passage defined by the flexible bellows and the frame provides a sealed connecting passage between the first compartment and the storage means.

2. The aircraft according to claim 1 , wherein the hatch arrangement comprises a second hatch cover movable parallel to the frame plane between an opened position and a closed position,
wherein the first hatch cover in the closed position abuts the second hatch cover in the closed position such that the frame aperture is closed, and
wherein the first hatch cover in the opened position is spaced apart from the second hatch cover in the opened position such that the frame aperture is open.

3. The aircraft according to claim 1 , wherein the hatch arrangement comprises biasing means for biasing at least one of the first and the second hatch cover to the closed position.

4. The aircraft according to claim 2 , wherein the hatch arrangement comprises at least one of an automatic and a manual actuating means for moving at least one of the first and/or the second hatch cover from the closed to the opened position.

5. The aircraft according to claim 2 , wherein the hatch arrangement establishes an airtight sealing of the frame aperture when at least one of the first and the second hatch cover is in the closed position.

6. The aircraft according to claim 1 , wherein the bellows arrangement comprises a biasing means for biasing the flexible bellows to the extended position.

7. The aircraft according to claim 1 , wherein the bellows arrangement comprises a gasket establishing an airtight sealing between the flexible bellows and an outer surface of a storage means located in the second compartment.

8. The aircraft according to claim 1 , wherein the bellows arrangement comprises at least one of an automatic and a manual actuation means for retracting the flexible bellows from the extended to the retracted position.

9. An aircraft comprising:
a first compartment;
a second compartment separated by a wall; and
a catering system comprising:
a galley adapted to be arranged in a the first compartment of the aircraft;
a storage means located in the second compartment of the aircraft;
a connecting means comprising:
a frame enclosing a frame aperture and extending in a frame plane;
a hatch arrangement mounted to the frame for selectively closing and opening the frame aperture and comprising at least a first hatch cover, the first hatch cover being movable parallel to the frame plane between an opened position and a closed position; and
a bellows arrangement mounted to the frame and comprising a flexible bellows, wherein the flexible bellows and the frame enclose a continuous passage terminating at one end in the frame aperture and wherein the flexible bellows has at least a retracted position and an extended position in a direction transverse to the frame plane,
wherein the connecting means is arranged in the wall such that the frame plane extends parallel to the wall and the hatch arrangement is arranged between the flexible bellows and the first compartment, such that, in the extended position, the flexible bellows extends from the frame to the storage means located in the second compartment, whereby the continuous passage defined by the flexible bellows and the frame provides a sealed connecting passage between the galley and the storage means.

10. The aircraft according to claim 1 , wherein the first compartment is a passenger compartment and the second compartment is a cargo compartment.

11. The aircraft according to claim 1 , wherein the wall is a floor portion of the aircraft and, in operation of the aircraft, the first compartment is arranged above the bellows arrangement.

12. The aircraft according to claim 3 , wherein the biasing means comprises a gas spring.

13. The aircraft according to claim 4 , wherein the actuating means comprises a cable drive moving at least one of the first and the second hatch cover by cable.
