Claims
- 1. An interface for adapting parallel horizontal rails of an ambulatory wheelstand frame to accept a seat for use as a wheelchair, said interface comprising:
- a pair of spaced parallel side members and a pair of spaced cross members interconnecting said side members, said side and cross members forming a rectangular frame structure;
- tab means on said frame structure for supporting said frame structure on the horizontal rails, said tab means includes a pair of spaced tabs extending outwardly from each of said side members to overlie the horizontal rails;
- locking means positioned on the rails, said locking means includes a collar located adjacent a forward end of each of the horizontal rails against which a forward one of said pair of tabs on each side member can abut to prevent forward movement of said frame structure on the wheelstand frame;
- lock means on said frame structure; and
- wherein said tab means, locking means and lock means are operably associated to detachably locate and lock said frame structure on the wheelstand frame.
- 2. The interface according to claim 1 wherein said collars are detachably connected to the horizontal rails.
- 3. The interface according to claim 1 wherein said locking means includes a bracket located adjacent a rearward end of each of the horizontal rails against which a rearward one of each of said pair of tabs on each side member can abut to prevent rearward movement of said frame structure.
- 4. The interface according to claim 3 wherein each of said brackets has a plate portion which overlies said rearward one of said tabs to prevent upward movement of said frame structure.
- 5. The interface according to claim 3 wherein each of said brackets is detachably connected to the horizontal rails.
- 6. The interface according to claim 1 including clip elements for attaching the seat to said frame structure.
- 7. An interface for adapting parallel horizontal rails of an ambulatory wheelstand frame to accept a seat for use as a wheelchair, said interface comprising:
- a pair of spaced parallel side members and a pair of spaced cross members interconnecting said side members, said side and cross members forming a rectangular frame structure;
- tab means on said frame structure for supporting said frame structure on the horizontal rails, said tab means includes a pair of spaced tabs extending outwardly from each of said side members to overlie the horizontal rails;
- locking means positioned on the rails;
- lock means on said frame structure, said lock means includes a pair of latches located on a forward one of said pair of cross-members which engage a forward end of each of the horizontal rails, said latches swing outwardly to engage an underside of each of the horizontal rails, confining each rail below a forward one of said tabs; and
- wherein said tab means, locking means and lock means are operably associated to detachably locate and lock said frame structure on said wheelstand frame.
