A mobile body support vehicle has a collapsible tubular frame. The frame includes longitudinally extending members formed by interconnected front in rear portions and transversely extending front intermediate bars and rear cross interconnecting the longitudinal members. The longitudinal members include detachable unions between the front and rear portions allowing the front and rear portions to be connected together and disconnected. The unions are each positioned substantially within a common plane oriented transversely with respect to the longitudinal members. The vehicle includes a front and rear pair of spaced apart wheels which are pivotally mounted to opposite sides of the frame and a pair of spaced apart intermediate wheels which are mounted on opposite sides of the frame at a location between the front and rear wheels. The intermediate wheels are larger than the front and rear wheels and include circumferential hand gripping members allowing the user to propel and control the vehicle. Fabric is stretched over the frame to form a surface adapted to receive and support a user\s body. In the preferred form of the invention, the tubular frame is fabricated from polyvinylchloride piping and connectors.

A collapsible mobile body support vehicle comprising: (a) a subframe comprised of a longitudinal support member having at least two segments connected by a releasable coupling, a front cross bar attached to one end of said longitudinal support member and a rear cross bar attached to the opposite end of said longitudinal support member, and intermediate cross bar attached to said longitudinal support member between said front cross bar and said rear cross bar, at least one wheel pivotably attached to the front cross member and at least one wheel pivotably attached to the rear cross bar; (b) a body frame comprised of a generally U-shaped front segment positioned above said subframe, a pair of rear side rails pivotably connected to said front segment at its ends, a rear support connecting said rear side rails to said intermediate cross bar, and a front support connecting said U-shaped frame to said front crossbar wherein said pivotable connections are positioned relative to said subframe releasable coupling so that when said coupling is released said U-shaped front segment may be folded back over said rear side rails and over a portion of said subframe; (c) a pair of intermediate wheels mounted to either side of said subframe along an axis generally parallel to said intermediate cross bar and between said front bar member and said rear cross bar; and (d) fabric attached to said body frame to form a surface adapted to receive and support a user\s body.
