Abstract
Abstract A TWO-PASSENGER TRICYCLE IN WHICH SEPARATE SADDLE AND HANDLEBARS ARE PROVIDED ON OPPOSITE SIDES OF AN AXIS DEFINED BY A MEDIAL, LONGITUDINAL FRAME MEMBER. A CENTRAL CRANKSHAFT IS JOURNALED ACROSS THE LONGITUDINAL AXIS AND A SET OF PEDALS ARE PROVIDED ON EACH SIDE OF THE LONGITUDINAL AXIS. AN INBOARD PEDAL OF EACH SET OF PEDALS IS CONNECTED BY CRANK ARMS TO THE CENTRAL CRANKSHAFT WHICH, IN TURN, IS CONNECTED BY SPROCKET WHEELS AND CHAIN TO A DRIVE WHEEL. THE MEDIAL SEATING SURFACE OF THE SADDLES ARE SPACED A GREATER DISTANCE HORIZONTALLY FROM THE AXIS OF ROTATION OF THE CRANKSHAFT THAN VERTICALLY THEREFROM SO THAT HORIZONTAL THRUST VECTOR ON THE PEDAL IS GREATER THAN THE VERTICAL THRUST VECTOR, ALLOWING PUSH PEDALING. OTHER FEATURES INCLUDE A NOVAL BRAKE CONTROL, REAR MOUNTING FEET FOR VERTICAL STORAGE AND KNOCKDOWN CONSTRUCTION.
