Claims
- 1. A portable sliding transfer device comprising a seat that is adapted to support a human user for movement between one body support, such as a bed, to another body support, such as a wheelchair, said device comprising:
- a) a lower support plate having a substantially flat top surface, and ends adapted to be removably positioned proximate and in contact with said body supports, and
- b) an upper seat which is attached to the lower support plate such that the upper seat is slidable over the top surface of the lower support plate and the upper seat is pivotable with respect to the top surface of the lower support plate.
- 2. The sliding transfer device of claim 1 wherein the lower support plate comprises a recessed track in the top surface, and the upper seat comprises a guide affixed to the bottom portion of the seat, said guide slidably fitting into the recessed track.
- 3. The sliding transfer device of claim 1 wherein the upper seat comprises means for reducing the friction between the upper seat and the lower support plate.
- 4. The sliding transfer device of claim 1 wherein the lower support plate comprises means for reducing the friction between the upper seat and the lower support plate.
- 5. The sliding transfer device of claim 1 wherein the top surface of the lower support plate is substantially rectangular, and the upper seat is slidable over the length of the top surface.
- 6. The sliding transfer device of claim 1 wherein the top surface of the lower support plate is curve-shaped, and the upper seat is slidable over the path of the curve.
- 7. The sliding transfer device of claim 6 wherein the top surface of the lower support plate comprises more than one curvature.
- 8. The sliding transfer device of claim 1 wherein the top surface of the lower support plate is S-shaped.
- 9. The sliding transfer device of claim 1 wherein the upper seat and the lower support plate are attached by a swivel joint.
- 10. The sliding transfer device of claim 1 wherein the upper seat comprises a flexible flap at one or more ends.
- 11. The sliding transfer device of claim 1 wherein the upper seat comprises a flexible flap at one or more ends, said flexible flap containing handles.
- 12. A portable sliding transfer device comprising a seat that is adapted to support a human user for movement between one body support, such as a bed, to another body support, such as a wheelchair, said device comprising:
- a) a curved lower support plate having a substantially flat top surface and ends adapted to be removably positioned proximate and in contact with said body supports, and
- b) an upper seat which is attached to the lower support plate such that the upper seat is slidable over the top surface of the lower support plate and the upper seat is pivotable with respect to the top surface of the lower support plate.
- 13. The sliding transfer device of claim 12 wherein the top surface of the lower plate comprises more than one curvature.
- 14. The sliding transfer device of claim 12 wherein the top surface of the lower support plate is S-shaped.
- 15. The sliding transfer device of claim 12 wherein the upper seat and the lower support plate are attached by a swivel joint.
- 16. The sliding transfer device of claim 12 wherein the upper seat comprises a flexible flap at one or more ends.
- 17. A portable sliding transfer device comprising a seat that is adapted to support a human user for movement between one body support, such as a bed, to another body support, such as a wheelchair, said device comprising:
- a) an S-shaped lower support plate having a substantially flat top surface and ends adapted to be removably positioned proximate and in contact with said body supports,
- b) a track attached to the top surface,
- c) an upper seat, and
- d) a swivel joint affixed to the bottom portion of the upper seat, said joint slidably attached to the track thereby attaching the upper seat to the lower support plate so that the upper seat is slidable and pivotable over the top surface of the lower support plate.
