Abstract
Abstract The present invention relates to an improved combination wheelchair-gurney apparatus. The improved wheelchair-gurney includes a pivoting back rest and foot rest which permit the wheelchair to be transformed into a gurney and vice versa. The combination wheelchair-gurney also includes transferring means associated with the foot rests, seat rest, and back rest which facilitate transferring a patient from the apparatus when in the gurney position to an adjacent bed or examining table. Furthermore, an additional wheel assembly is included which may provide support for the back rest when the apparatus is in the gurney position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
202 words
An improved combination wheelchair-gurney apparatus comprising: (a) a wheelchair frame having attached thereto a pair of swivellable front wheels, a pair of rear wheels and a pair of removable arm rests; (b) a pair of foot rests, each said foot rest being pivotally connectable to said wheelchair frame; (c) a back rest being pivotally connectable to said wheelchair frame at a first pivot point; (d) a seat rest being hinged to a portion of said back rest; and (e) a wheel assembly being slidably connectable to said wheelchair frame and being adapted to support said back rest, said wheel assembly including a pair of elongated members which are extendible within said frame, a wheel rotatably attached to an outer end of each said elongated member, and a stabilizing bar attached to each said elongated member adjacent its outer end and extending angularly therefrom; (f) whereby, said back rest and each respective said foot rest may be pivotally moved such that said back rest, each said foot rest and said seat rest lie in a horizontal plane thereby forming a gurney and said wheel assembly may be extended from said wheelchair frame to support said back rest and facilitate movement of said apparatus.
Claim 2
Dependent Claim
202 words
An improved combination wheelchair-gurney apparatus comprising: (a) a wheelchair frame having attached thereto a pair of swivellable front wheels, a pair of rear wheels and a pair of removable arm rests; (b) a pair of foot rests, each said foot rest being pivotally connectable to said wheelchair frame; (c) a back rest being pivotally connectable to said wheelchair frame at a first pivot point; (d) a seat rest being hinged to a portion of said back rest; and (e) a wheel assembly being slidably connectable to said wheelchair frame and being adapted to support said back rest, said wheel assembly including a pair of elongated members which are extendible within said frame, a wheel rotatably attached to an outer end of each said elongated member, and a stabilizing bar attached to each said elongated member adjacent its outer end and extending angularly therefrom; (f) whereby, said back rest and each respective said foot rest may be pivotally moved such that said back rest, each said foot rest and said seat rest lie in a horizontal plane thereby forming a gurney and said wheel assembly may be extended from said wheelchair frame to support said back rest and facilitate movement of said apparatus.
Claim 3
Dependent Claim
63 words
The invention of claim 1, wherein each of said back rest, said wheelchair frame and said pair of foot rests includes means attached thereto for transferring a patient on said apparatus from said apparatus to an adjacent horizontal surface, each said means being capable of spanning between each of said back rest, said wheelchair frame, and said foot rest and an adjacent structure.
Claim 4
Dependent Claim
