Abstract

A tabletop which is effectively easily retrofitable onto a wheelchair without any drilling or welding. The design can support an electronic device for computer-assisted living or simply provide a worksurface for reading or eating. The tabletop assembly is stabilized by an adjustable support structure. A mounting clamp may be provided to mount to the frame of the wheelchair, or a welded mounting tube can be provided which attaches onto the wheelchair footrest. The tabletop can be used in tandem with an optional horizontal panel which is mounted over the tabletop and top-hat brackets to support items such as an electronic device or a beverage. Alternatively, the tabletop can include a control panel which includes, for example, one or more pushbuttons, joy sticks and/or trackballs.

6. A table as recited in claim 1, wherein the tabletop comprises an enclosure.

7. A table as recited in claim 6, wherein the enclosure comprises a bottom panel and at least one contoured edge.

8. A table as recited in claim 6, wherein the enclosure comprises a bottom panel and edges having recesses formed therein, and wherein the enclosure further comprises a top panel which has edges which are configured to be received in the recesses, thereby supporting the top panel relative to the bottom panel.

9. A table as recited in claim 8, wherein the top panel has a circular cutout formed therein.

10. A table as recited in claim 8, further comprising brackets disposed between the top and bottom panels.

11. A table as recited in claim 10, wherein the brackets which are disposed between the top and bottom panels have air holes formed therein.

12. A table as recited in claim 1, further comprising a bracket disposed relative to the tabletop and the support structure such that a position of the tabletop is adjustable relative to the support structure.

13. A table as recited in claim 12, wherein the bracket which is disposed relative to the tabletop and the support structure such that a position of the tabletop is adjustable relative to the support structure includes a plurality of holes which are configured to receive corresponding structure on the support structure for securing the position of the tabletop relative to the support structure.

14. A table as recited in claim 1, wherein the tabletop comprises a bottom panel, further comprising a bracket which is disposed under the bottom panel and which is configured to secure to the support structure.

15. A table as recited in claim 1, wherein the support structure is adjustable such that a height of the tabletop is adjustable.

16. A table as recited in claim 1, wherein the support structure is securable in the mounting means at different positions, such that a height of the tabletop is adjustable.

17. A table as recited in claim 1, wherein the support structure is removable from the mounting means, and the mounting means is configured to receive a vertical tube which is configured to support an IV bag.

18. A table as recited in claim 1, wherein the mounting means comprises a mounting clamp configured to secure to a frame of the wheelchair.

19. A table as recited in claim 1, wherein the support structure comprises an upper support assembly and a lower support assembly, wherein the upper support assembly is configured to support the tabletop, is configured to telescope relative to the lower support assembly to facilitate height adjustment of the tabletop, and is configured to rotate relative to the lower support assembly such that the tabletop is orientateable away from the wheelchair.

20. A table as recited in claim 19, wherein the upper support assembly comprises a vertical tube which is configured to interact with corresponding structure on the lower support assembly to facilitate adjustment and securement of the vertical tube relative to the lower support assembly.

21. A table as recited in claim 20, wherein the lower support assembly comprises a tube and a plunger which is disposed on the tube and has a tip, wherein the vertical tube includes at least one opening which is configured to receive the tip of the plunger.

22. A table as recited in claim 19, further comprising a tabletop assembly which comprises a panel and a mounting bracket disposed on the panel and configured to engage corresponding structure on the upper support assembly for adjusting and securing a position of the panel.

23. A table as recited in claim 19, further comprising an inner mounting clamp which is configured to mount to the frame of the wheelchair, an outer mounting clamp which is configured to clamp to the lower support structure, and structure which is clamped by both the inner and outer mounting clamps such that the outer mounting clamp is spaced away from the inner mounting clamp.

24. A table as recited in claim 23, wherein both the inner and outer mounting clamps are comprised of a plurality of clamp sections held together by fasteners.

25. A table as recited in claim 1, wherein the tabletop comprises a control panel having at least one manually operable component disposed thereon, said manually operable component comprising at least one of a pushbutton, a joystick and a trackball.
