Abstract

A telescoping aircraft door is disclosed having first and second panels that slide relative to one another to extend and retract as the door closes and opens, respectively. The first panel is hinged to the door frame in a traditional manner, and the second panel is fixed to the door frame by a linkage that limits the arc of the second panel. By selecting the location and length of the linkage, the relative movement of the two panels can be predictably controlled to reduce the depth of the door when closed and the length of the door when opened.

First claim

We claim:

1. A two panel door for an aircraft compartment, comprising:
a first panel hingedly connected to a door frame, the first panel having a width of approximately half of the door frame to which it is mounted;
a second panel mounted on the first panel in sliding translation thereon, the second panel extending parallel to the first panel in a sliding arrangement;
a linkage coupling the door frame to the second panel at a distance of approximately one fourth a length of the door frame, the linkage fixing a distance that the second panel can extend from the door frame, the linkage coupled to the door frame and the second panel so as to permit relative pivoting between connected ends;
wherein the two panel door operates such that the ends of the panels are adjacent in a closed configuration and the faces of the panels are adjacent in the open configuration.

2. The two panel door of claim 1 , further comprising an extendable locking mechanism on the first panel to prevent the door from opening when the extendable locking mechanism is in a first position.

3. The two panel door of claim 2 , wherein the extendable locking mechanism is a coat hook.

4. The two panel door of claim 1 , wherein the first panel includes first and second spaced apart horizontal rails and the second panel includes a pair of wheels configured to ride in the rails and support the sliding relationship therebetween.

5. The two panel door of claim 1 , wherein the width of the first panel is approximately equal to a width of the second panel.

6. The two panel door of claim 1 , wherein the first panel is connected to the door frame via a piano hinge.
