Abstract
The invention relates to a combined trailer/wheelchair which can either be towed behind a powered cart or be manually pushed as a wheelchair and which includes features such as a removable or telescoping tow bar, an articulated hitch mechanism adapted to connect the tow bar to a towing cart, arms to prevent inadvertent rearward tipping of the trailer when uncoupled from a towing cart, and easy disassembly.
Claims9
A combined trailer/wheelchair comprising a frame (13), a pair of laterally spaced and aligned wheels (18) rotatably supported proximate the rear end of said frame, said wheels having a common axis of rotation extending normally to a longitudinal frame axis (15), a pedestal (26) mounted upon said frame and longitudinally spaced forwardly of the axis of rotation of said wheels, a passenger seat (30) supported upon said pedestal, said frame including a foot support portion (40) disposed proximate the forward end of said frame, a tow bar (48) mounted along the longitudinal axis of said frame, means (50) for retaining said tow bar in a position projecting forwardly of said frame, a pair of caster-type wheels (46) transversely spaced and mounted upon said frame proximate the forward end of said frame, said caster-type wheels being movable to be non supportive of said frame when the tow bar is in its forwardly projecting position, and a hitch device (56) secured to the forward end of said tow bar and adapted to be removably connected to a towing cart.
