Abstract:
A collapsible wheelchair, comprising:a first wheel and a second wheel secured on opposites sides of a central support frame designed to support a seat member, the first wheel and the second wheel defining a space within the circumference of each wheel;the central support frame including a first frame member connected to the first wheel such that the first frame member may selectively move relative to the first wheel and a second frame member connected to the second wheel such that the second frame member selectively moves relative to the second wheel;a connecting member connecting the first frame member to the second frame member in a manner permitting the first frame member and the second frame member to be selectively moved toward and away from each other, thereby, permitting the collapse of the wheelchair;at least one guide wheel coupled to the central support frame for supporting the wheelchair; andwherein the wheelchair is collapsed by moving the first frame member and the second frame member relative to the first wheel and the second wheel, respectively, to position the first frame member and the second frame member substantially within the space defined by the first wheel and the second wheel, and simultaneously collapsing the connecting member to permit the first frame member and the second frame member to be drawn toward each other.
