Abstract

A door assembly for a vehicle. The door assembly includes a door frame, a door panel, a rotating strut, and a linear door guide. The door opens and closes through a combination of rotating and sliding motion, which minimizes the required operational footprint. The strut is mounted on the door panel such that the strut is hidden from view when the door is in an open position.

First claim

What is claimed is:

1. A door assembly comprising:
a door frame;
a door panel movable between an open position and a closed position;
one or more strut pivotably connected to the door frame and to a central region of the door panel; and
at least one door guide, comprising:
a linear slide rail;
a slide saddle; and
a hinge connecting the slide saddle to a first edge face of the door panel,
wherein the door panel is pivotably movable at an end of the strut and is slidably movable along the linear slide rail; and
wherein, when the door panel is in the open position, the door panel is parallel to the linear slide rail and the at least one strut is enclosed between the door panel and the linear slide rail.

2. The door assembly of claim 1 , comprising a door handle and a lock.

3. The door assembly of claim 1 , comprising two or more struts and/or door guides.

4. The door assembly of claim 1 , wherein the one or more strut is mounted to the door panel such that the one or more strut is located on a side of the door panel away from a passageway when the door panel is in the open position.

5. The door assembly of claim 1 , wherein the door frame comprises a first vertical support, a second vertical support, and a third vertical support.

6. The door assembly of claim 5 , wherein the door assembly is configured such that opening the door causes the door panel to rotate toward a first vertical support and slide toward a second vertical support.

7. The door assembly of claim 5 , wherein the first and second vertical supports are disposed on a hinge side of the door panel, in a plane substantially perpendicular to the door panel when the door panel is in the closed position, and
wherein the third vertical support is disposed at a projected point between the first and second vertical supports and engages with a second edge face of the door panel when the door panel is in the closed position.

8. The door assembly of claim 7 , wherein the third vertical support latches and/or locks the door panel in the closed position.

9. The door assembly of claim 5 , wherein the one or more strut is mounted on a side of the door panel that faces the linear slide when the door panel is in the open position.

10. The door assembly according to claim 5 , wherein the linear slide rail is attached to, and extends linearly between, the first and second vertical supports.

11. An aircraft comprising a door assembly, the door assembly comprising:
a door frame;
a door panel movable between an open position and a closed position;
one or more strut pivotably connected to the door frame and to a central region of the door panel; and
at least one door guide comprising:
a linear slide rail;
a slide saddle; and
a hinge connecting the slide saddle to a first edge face of the door panel,

wherein the door panel is pivotably movable at an end of the strut and is slidably movable along the linear slide rail; and
wherein, when the door panel is in the open position, the door panel is parallel to the linear slide rail and the at least one strut is enclosed between the door panel and the linear slide rail.

12. The aircraft of claim 11 , wherein the door assembly is installed independent from adjacent cabin monuments of the aircraft.

13. The aircraft of claim 11 , wherein the door assembly is configured to provide rapid decompression venting.

14. A method for operating a door, the method comprising:
providing a door assembly comprising:
a door frame comprising a first vertical support, a second vertical support, and a third vertical support;
a door panel movable between an open position and a closed position and comprising a first side and a second side;
one or more strut pivotably connected to the door frame and to the first side of the door panel; and
at least one door guide, the door guidc comprising:
a linear slide rail disposed between the first and second vertical supports;
a slide saddle; and
a hinge connecting the slide saddle to a first edge face of the door panel,

wherein the first and second vertical supports are disposed on a hinge side of the door panel in a plane substantially perpendicular to a plane defined by the door panel in the closed position,
wherein the third vertical support is disposed at a projected point between the first and second vertical supports and engages with a second edge face of the door panel when the door panel is in the closed position, and
wherein the door panel is pivotably movable at an end of the strut and is slidably movable along the linear slide rail;

moving the door panel linearly between the first and second vertical supports while rotating the door panel toward or away from the third vertical support; and
wherein, when the door panel is in the open position, the door panel is parallel to the linear slide wall and the at least one strut is enclosed between the door panel and the linear slide rail.

15. The method according to claim 14 , comprising opening the door panel by moving the door panel in a linear motion toward the second vertical support while simultaneously rotating the door panel away from the third vertical support.

16. The method according to claim 15 , comprising closing the door panel by moving the door panel in a linear motion toward the first vertical support while simultaneously rotating the door panel toward the third vertical support.

17. The method according to claim 14 , comprising closing the door panel by moving the door panel in a linear motion toward the first vertical support while simultaneously rotating the door panel toward the third vertical support.
