  • Patent number: 4087108
    Abstract: A three-place contact cambering vehicle having a pair of trailing arms pivoted to a front frame for up and down swinging movement on either side of the frame and interconnected by spur gearing that stabilizes and holds the frame and connected steering column at a predetermined rake angle while permitting equal and opposite movement of the trailing arms. This gearing can be locked to lock the trailing arms and frame together for vehicle parking purposes. An adjustment is provided to permit the rake angle of the frame to be selectively varied to change steering column rake angle and to further permit the frame and steering column to be collapsed toward the trailing arms and subsequently locked to provide a compact, low profile vehicle for transportation or storage purposes.

  • Patent number: 4067589
    Abstract: A foldable bicycle including a frame having a seat structure and a handlebar structure thereon. A front wheel is rotatably mounted on the frame structure through a front column, and a rear wheel is mounted on the frame structure and is powered through a pedal structure including a sprocket connected to the rear wheel by a chain drive. The main frame is foldable about a hinge point in the area of the sprocket through a unique hinge release and locking mechanism. Moreover, the front wheel is rotatable through the front column in a 180.degree. arc so that the front and back wheels become axially aligned when the hinge locking mechanism is released so that a front portion of the frame section can swing about in a 180.degree. arc to become somewhat parallel to a rear portion thereof. In addition, the present invention provides a unique seat structure which can be collapsed and raised to a desired level.

  • Patent number: 4054300
    Abstract: A cambering vehicle having a pair of trailing arms pivoted to the front steering frame for up and down swinging movement on either side of the steering frame and interconnected by differential gearing that stabilizes and holds the steering frame at a predetermined rake angle while permitting equal and opposite movement of the trailing arms. This gearing can be locked to lock the trailing arms and steering frame together for vehicle parking purposes. An adjustment is provided to permit the rake angle of the steering frame to be changed and to further permit the steering frame to be collapsed toward the trailing arms and locked to provide a low profile position for transportation or storage purposes.

  • Patent number: 4045048
    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.

  • Patent number: 4026573
    Abstract: A portable foldable motor scooter with a substantially triangular chassis, each corner of which is pivotable and one leg of which is hinged to allow the chassis to be folded to a collapsed condition. A steering column is pivotally connected to the forward corner of the chassis and is detachable from the chassis. The driver's seat is supported on front and rear linkages, the front linkage including a triangular portion containing the leg hinge of the chassis. A single removable pin normally locks this hinge and maintains the front seat-supporting linkage rigid. Upon removal of the pin the chassis can be folded to its collapsed position and the seat can be swung downwardly toward the rear wheel and can be latched to the rear wheel fender, holding the chassis in its collapsed position. The steering column has handle bars which can be swung inwardly and fastened so as not to protrude from the folded vehicle.

  • Patent number: 4002351
    Abstract: This invention relates to an improvement in folding girl's and tandem bicycles. The improvement expands the capability of bicycle folding means into girl's and tandem model configurations and provides a commonality of construction which can be incorporated into men's model configurations. The improvement disclosed is a detent for retaining the articulated latches securely locked thereby avoiding inadvertant release when the bicycle is ridden. An eccentric adjustment is provided to adjust out the looseness in the folding joints to overcome the problems of manufacturing tolerances and normal wear. Also disclosed is a tandem style which is no larger than the single rider model, except that it has provisions for a tandem seat and a tandem set of pedals.
