United States Patent 4767130
Abstract:
A foldable pedicab has a foldable assembly which includes a main frame, two back frames mounted rotatably on the main frame, two seat frames mounted rotatably on the back frames respectively, two armrest members mounted rotatably on the back frames respectively, and two footrests mounted rotatably on the main frame. The seat frames are locked releasably on the main frame. The armrest frames are locked releasably on the seat frames. A swing wheel is mounted removably on leading end of the foldable assembly. Two main wheels are mounted removably on opposite sides of the foldable assembly. If necessary, a driving wheel assembly may be mounted removably on tail end of the foldable assembly so that the pedicab can be drived by a person riding on the driving wheel assembly. In absence of the driving wheel, the pedicab can form a hand-pushable wheelchair. When the driving wheel assembly, main wheels, and swing wheel are removed from the foldable assembly, the foldable assembly can be folded into a compact portable unit. The driving wheel assembly, swing wheel, and main wheels are then attached to the foldable assembly thereby forming a pushable small unit.
