Aircraft multi-function overhead space access module

Claim 2

A multi-function access module for use within an aircraft to enable access to an overhead storage area, comprised of: an enclosure having at least one wall, said wall having an outside surface and an inside surface; a partition that is movable from a closed position to an open position, said partition being suitably attached to said at least one wall; and a ladder movably positioned within said enclosure between a stowed position, wherein said ladder takes up substantially no area within said enclosure, and an extended position, wherein said ladder may be used to easily access said overhead area; wherein a floor portion is attached to said at least one wall for securing said ladder in said extended position.

Claim 3

The apparatus of claim 1 , wherein said ladder is movable between a substantially upright position and an inclined position.

Claim 4

The apparatus of claim 1 , further comprising at least one track-mount mechanism having a curved slot, said track-mount mechanism being suitably attached to the inside surface of said wall and operatively coupled to said ladder for assisting in defining a path of travel of said ladder when said ladder is moved between said extended and said retracted positions.

Claim 5

The apparatus of claim 3 , wherein said ladder is attached for pivotal and sliding movement relative to said track-mount mechanism.

Claim 6

The apparatus of claim 3 , further comprising a rod shaped dowel pin operably associated with said ladder and interposed through said curved slot of said track-mount mechanism, said dowel pin permitting pivotal movement thereabout of said ladder as said ladder is moved between said stowed and extended positions.

Claim 7

The apparatus of claim 1 , further comprising a floor panel that is attached to said wall.

Claim 8

The apparatus of claim 1 , further comprising a ceiling panel having an access opening sufficiently large enough to permit a person to climb there through.

Claim 9

The apparatus of claim 1 , wherein said ladder has at least one leg, said leg having a bottom end to which a roller is mounted for facilitating sliding movement of said bottom end of said ladder.

Claim 10

The apparatus of claim 8 wherein said floor panel has at least one retaining pocket fixedly mounted to said floor panel for capturing and retaining said roller for holding said ladder in said extended position.

Claim 11

The apparatus of claim 1 , wherein said partition comprises a bi-fold door.

Claim 12

The apparatus of claim 1 , wherein said ladder is further comprised of a first half having a bottom end and a second half having a top end, said bottom end of said first half being rigidly attached to said top end of second half.

Claim 13

The apparatus of claim 1 , further comprising at least one handrail suitably attached to the inside surface of said at least one wall.

Claim 14

A multi-function access module for enabling access to an overhead area within a fuselage of an aircraft, as well as providing a changing area for a crewmember, said access module comprising: a generally box shaped enclosure having a plurality of walls; a partition that is movable from a closed position to an open position, said partition being suitably attached to at least one of said walls to form a doorway allowing entry and egress from said box shaped enclosure; a track-mount mechanism that is fixedly attached to at least one of said walls; and a ladder situated within said enclosure that is movable between a stowed, substantially upright position, and an extended, inclined position, said ladder being coupled to said track-mount mechanism for pivoting and sliding movement relative to said track-mount mechanism, said ladder being held against one or more walls of said enclosure when in said stowed position such that substantially an entire interior area of said enclosure is unobstructed and may therefore be used as a changing room by a crew member; wherein said ladder is secured in said extended position by one of said plurality of walls.

Claim 15

A multi-function access module for enabling access to an overhead area within a fuselage of an aircraft, as well as providing a changing area for a crewmember, said access module comprising: a generally box shaped enclosure having a plurality of walls; a partition that is movable from a closed position to an open position, said partition being suitably attached to at least one of said walls to form a doorway allowing entry and egress from said box shaped enclosure; a track-mount mechanism that is fixedly attached to at least one of said walls; and a ladder situated within said enclosure that is movable between a stowed, substantially upright position, and an extended, inclined position, said ladder being coupled to said track-mount mechanism for pivoting and sliding movement relative to said track-mount mechanism, said ladder being held against one or more walls of said enclosure when in said stowed position such that substantially an entire interior area of said enclosure is unobstructed and may therefore be used as a changing room by a crew member; wherein said ladder is secured in said extended position by one of said plurality of walls.

Claim 16

The apparatus of claim 13 , wherein said plurality of walls is comprised of: a generally rectangular shaped first wall; a generally rectangular shaped second wall that is attached to said first wall; and a generally rectangular shaped third wall that is attached to said second wall.

Claim 17

The apparatus of claim 14 , further comprising a roller; and wherein said ladder comprises a leg having a bottom end, said roller being coupled to said bottom end to facilitate movement of said bottom end when said ladder is moved between said extended and stowed positions.

Claim 18

The apparatus of claim 15 wherein one of said plurality of walls is a floor panel that has at least one retaining pocket for capturing and retaining said roller when said ladder is moved into said extended position to secure the ladder in said extended position.

Claim 19

The apparatus of claim 13 , further comprising a ceiling panel suitably attached to at least one of said first, second, or third wall panels, said ceiling panel having an access opening sufficiently large enough to permit a person to pass through to gain access to said overhead area.
