- 2. The emergency stretcher of claim 1, wherein said undercarriage further includes a scissor-type lift mechanism operably mounted between said tubular frame members and said wheeled base, said lift mechanism is adapted to adjust the vertical height of the undercarriage between an elevated position, a collapsed position, and a number of relative positions therebetween.
- 3. The emergency stretcher of claim 1, wherein said tubular frame members have first and second ends, and said undercarriage includes first and second movable end extensions rotatably mounted to said first and second ends, respectively.
- 4. The emergency stretcher of claim 1 wherein said tubular frame members provide two cavities each being accessible by a respective one of a pair of slots, said undercarriage further comprising a first crossbar mounted between said tubular frame members, and a second cross bar slidably mounted in said cavities through said slot, said stretcher includes a pair of fixed-length leg members and a pair of telescoping variable-length leg members, said fixed length leg members at uppermost ends thereof are rotatably connected to said first crossbar, and said variable-length members at uppermost ends thereof are rotatably connected to said second crossbar, and wherein said leg members at lowermost ends thereof are rotatably connected to said wheeled base.
- 5. The emergency stretcher of claim 1, further comprising at least one actuator operationally connected to said securing device and mounted to an adjustable end extension mounted between said frame members, said at least one actuator is adapted to permit said vertical movement of said undercarriage when operated.
- 6. An emergency stretcher, comprising:a patient support; and a vertically adjustable wheeled undercarriage supporting said patient support, said undercarriage having opposed first and second longitudinal frame members, and first and second movable end extensions interconnecting said longitudinal frame members, said end extensions are rotatably mounted to said undercarriage and each is adapted to be releasably secured in at least one of a plurality of positions from about parallel to said longitudinal frame members and to about perpendicular to and below said longitudinal frame members.
- 7. The emergency stretcher of claim 6, wherein said undercarriage further comprises a pair of side-arm supports pivotably connected to respective ones of said tubular frame members.
- 8. The emergency stretcher of claim 6, wherein said patient support includes a vertically adjustable back-rest portion, a seat portion having a first and second ends, and a vertically adjustable leg support portion, wherein said back-rest portion is hinged to said first end of said seat portion, and said leg support is hinged to said second end of said seat portion.
- 9. The emergency stretcher of claim 8, wherein said vertically adjustable back-rest portion is positionable between an upright position and a reclined position and a number of positions therebetween by a lifting device having upper and lower ends, said upper end of said lifting device attached to said back rest portion, and said lower end of the lifting device is rotatably mounted to said undercarriage.
- 10. The emergency stretcher of claim 8, wherein said undercarriage further comprises a holding device and a slidable arm adapted to vertically adjust said leg support portion between elevated and reclined positions.
- 11. The emergency stretcher of claim 8, wherein said back rest portion has an integrally formed hinged end, said ends of said seat portion are integral formed hinged ends, and said leg support portion has an integrally formed hinged end, wherein said hinged ends form a waffle-type engagement.
- 12. The emergency stretcher of claim 6, comprising a cushion having a plurality of buttons provided in a button arrangement, wherein said patient support has a front surface, a back surface, and a plurality of through-bores, wherein said cushion is releasably secured to said front surface of said patient support by said plurality of buttons passing through said through-bores of said patient to engage said back surface of said patient support.
- 13. The emergency stretcher of claim 6 wherein said patient support includes a seat portion and a pair of pins, wherein said seat portion is mounted between said tubular frame members by said pair of pins, and said tubular frame members have first and second ends, and said undercarriage includes first and second movable end extensions rotatably mounted to said first and second ends.
- 14. The emergency stretcher of claim 6 wherein said undercarriage comprises a wheeled base having four wheels each including a wheel brake.
- 15. The emergency stretcher of claim 6, wherein each of said end extensions is movable to a planar position, to a beveled position, and to position about perpendicular to and below said tubular frame members.
- 16. The emergency stretcher of claim 6, further comprising a pair of side arm supports, each one of said side arm supports are mounted to a respective one of said longitudinal frame members, and each said side-arm supports has a docking port for accessory attachment.
- 17. The emergency stretcher of claim 6 further comprising a securing device adapted to releasably arrest vertical movement of said patient support by said undercarriage.
- 18. The emergency stretcher of claim 6, wherein said undercarriage further includes a wheeled base and a scissor-type lift mechanism operably mounted between said tubular frame members and said wheeled base, said lift mechanism is adapted to adjust the vertical height of the undercarriage between an elevated position, a collapsed position, and a number of relative positions therebetween.
- 19. The emergency stretcher of claim 6, further comprising a securing device accommodated within a cavity of said first longitudinal frame member for arresting said vertical movement of said undercarriage.
- 20. The emergency stretcher of claim 19 wherein said securing device comprises a bar with a plurality of spaced apart notches and a latch for selectively engaging said notches.
