Abstract: An articulated cambering vehicle in which a pair of trailing arms are interconnected to each other and to a steering frame by stabilizer linkage which includes a support and locking plate pivoted to the frame and a pair of side links each being pivotally connected to the support and locking plate and to the trailing arms. A locking device is employed to lock the plate at an infinite number of positions to lock up the vehicle in a stand-up position for parking purposes. One of the side links can be telescoped and shortened to allow the vehicle to be collapsed into a folded low-profile position. By locking the side link in the telescoped position the vehicle is rigidly maintained in the folded position.

Abstract: A sport vehicle comprising a vehicle frame having a step on its upper surface and an upstanding handle rod at its front end. At the lower surface of the front of the frame a front wheel axle is mounted having a pair of front wheels at its ends, the middle portion of the axle being rotatably supported through a steering shaft having a negative caster angle, the vehicle frame and the front wheel axle being interconnected through a resilient member. A single rear wheel is mounted on the vehicle frame at the lower surface of the rear portion thereof. One of the three wheels can be a driving vehicle wheel in which case a pedal lever is swingably mounted on the frame for upwards and downwards movement to drive a longitudinally extending flexible member for reciprocation in forwardly and rearwardly direction.
