By turning the wheels through 90 degrees to the longitudinal direction, the transporter can be driven along a path (Y) in either direction, and steered by varying the differential speed of the wheels. A container carried on the deck can be moved and rotated in directions X', Y' and Z'.

Abstract: A human-powered recumbent tricycle with an articulated frame that permits leaning of the single-wheeled front sub-frame (10) during turns. While the seat (20) and pedal crank (18) move the driver's body with the leaning front sub-frame (10), the two-wheeled rear sub-frame (71) carries the handlebar (90) for optimum driver control of vehicular orientation. Steering of the front wheel (16) is accomplished by two cables (60L, 60R) within housings (61L, 61R) that provide immunity from distortions caused by articulation (100) rotations during leaning. Front wheel (16) drive utilizes a universal joint hub (30) for continuous power drive and no chain (40, 50) twist throughout the full turning radius. High seat (20) height and narrow wheelspan of the two rear wheels (80L, 80R) provide for improved visibility and traffic penetration on congested urban streets. A low cargo rack (75) is provided such that carrying cargo lowers the overall center of gravity and increases vehicular stability.

Abstract: A semi-recumbent bicycle having a conventional wheelbase. The frame of the bicycle has a unique geometric configuration in that the main tube of the frame is straight such that its axis forms an acute angle with the line of the ground so that the main tube is higher at its rear end than at its front end. This novel arrangement permits the semi-recumbent bicycle to be more easily manufactured and assembled because all of the major components of the bicycle are aligned directly off of the main tube and there is no need, with the exception of the rear triangle which supports the rear wheel, to align and fit together the component parts of the bicycle. Moreover, the semi-recumbent bicycle may be operated by riders of many different sizes because the bicycle seat is adjustable along the main tube toward and away from the foot pedals. The unique geometric configuration also enhances the range of adjustability of the seat and makes it possible to provide a luggage rack which is connected to the back of the seat.
