Abstract

A storage compartment with a hinged cover which acts as an armrest is fixedly attached to the frame of a wheelchair and does not interfere with wheelchair folding, armrest frame removal, or occupant operation of propulsion rings and brakes. The storage compartments store small articles, identification, and money.

Claims

1. Storage compartments acting as a wheelchair armrest comprising:

at least one storage compartment of substantially rigid material extending substantially above the top of a wheelchair armrest frame;

at least one deep storage compartment of substantially rigid material extending substantially below the top of a wheelchair armrest frame;

a cover for said storage compartments;

means on said storage compartments to support said compartment cover in a closed position;

a compartment cover hinge means;

means to hold said compartment cover closed;

means to open said compartment cover;

means to mount one of said storage compartments to a wheelchair armrest frame.

2. The wheelchair armrest storage compartments according to claim 1 wherein the storage compartment cover comprises substantially rigid material having all exterior surfaces and corners rounded and being supported from below around the cover bottom periphery by a ridge on the interior surface of exterior vertical walls of said compartments with said cover being recessed below the top of the vertical compartment walls and having a cover upper surface periphery slightly above the level with the top of said supporting compartment walls.

3. The wheelchair armrest storage compartments according to claim 1 wherein the storage compartment substantially above wheelchair armrest frame comprise a substantially rigid horizontal bottom being attached to the wheelchair armrest frame and substantially rigid veritcal walls supporting said compartment cover, said horizontal bottom being ridgidly attached to said vertical walls with storage volume contained within said horizontal and vertical walls being accessible from said open compartment cover.

4. The wheelchair armrest storage compartments according to claim 1 wherein the means to support said compartment cover comprises a ridge attached on the interior of vertical exterior compartment walls and the top of vertical internal compartment walls with the vertical exterior walls extending above the cover support ridge around the cover periphery.

5. The wheelchair armrest storage compartments according to claim 1 wherein the means to hold said compartment cover closed comprises a latch element on said cover which releasably engages an interior wall between said compartments.

6. The wheelchair armrest storage compartments according to claim 1 wherein the compartment cover hinging means comprises a flexible fabric being attached to an interior surface of said compartment cover and being attached to interior surface of a vertical wall of said storage compartments.

7. The wheelchair armrest storage compartments according to claim 6 wherein said compartment cover hinging means further comprises hinge fabric long enough between attachments to permit said compartment cover to hang outside and approximately parallel to a substantially vertical exterior compartment wall when fully open, said hinge fabric being folded within said storage compartment with said compartment cover closed.

8. The wheelchair armrest storage compartments according to claim 1 wherein said storage compartment mounting means comprises threaded means attaching said storage compartment bottom to the top of wheelchair armrest frame and maintaining said storage compartment in the vertical load bearing path between armrest forces and said wheelchair armrest frame.

9. The wheelchair armrest storage compartments according to claim 1 wherein the means to open said compartment cover comprises flat ribbonlike material attached to the interior compartment cover surface, said ribbonlike material passing between said storage compartment vertical wall and said closed compartment cover and being used by the wheelchair occupant to apply vertical opening forces to said closed compartment cover.

10. The wheelchair armrest storage compartments according to claim 1 wherein said at least one deep storage compartment comprises substantially vertical substantially rigid walls rigidly attached to a substantially horizontal substantially rigid bottom forming storage volumes with compartment liners, said deep storage compartment being adjacent to said wheelchair armrest frame outside the occupant space and being rigidly attached to said storage compartment above wheelchair armrest frame with both compartments being accessible from the same open compartment cover.

11. The wheelchair armrest storage compartments according to claim 10 wherein the compartment liners comprise:

means to store items;

means to raise liners vertically relative to deep storage compartment walls;

means to releasably hold liners in a raised position.

12. The wheelchair armrest storage compartments according to claim 11 wherein the means to store items comprises a storage volume with three vertical liner sides separated by shelves, said storage volumes being accessible from the open liner side and open liner top and being slideably confined within substantially vertical deep storage compartment walls.

13. The wheelchair armrest storage compartments according to claim 11 wherein the means to raise said compartment liners comprises a flexible cord attached to the top of said liner forming a loop accessible from an open compartment cover to the wheelchair occupant for raising said liner vertically in the deep storage compartment.

14. The wheelchair armrest storage compartments according to claim 11 wherein the means to releasably hold liners in a raised position in said deep storage compartment comprises a latch structure with a substantially horizontal liner latch edge being housed within the liner volume while being forced by a spring mechanism outward through an opening in the vertical liner side to be in forcible contact with said storage compartment vertical wall with the horizontal liner latch edge engaging the top of said deep storage compartment vertical wall holding said removeable liner in a raised position.
