  • Patent number: 4813466
    Abstract: An improved support track assembly for both protecting and improving the flotation and mobility of the resilient wheels of a vehicle is disclosed herein that comprises both a manually operable retention assembly for fastening the track into an endless belt around the vehicle wheel, and a track storage reel that conveniently positions the track under the wheel and in alignment therewith prior to installation. The improved support track is formed from a plurality of track members that are pivotally interconnected by means of connector pins, and the retention assembly is formed from a retaining pin having a first end that is transversely insertable into a track member in a connector-pin capturing position, and a second pin formed from a resilient loop of spring steel. When the retaining pin is inserted into a pin-capturing position, the terminus of the loop is resiliently biased in a latching position.

  • Patent number: 3966220
    Abstract: Transportation Apparatus is disclosed herein involving a system whereby small electrically driven vehicles are carried in a transporter vehicle. A loader is movably mounted on the transporter for loading and unloading the small vehicles onto the transporter in selected storage spaces. Each small vehicle is provided with a telescoping frame for shortening the wheelbase for storage purposes and for extending the wheelbase for independent vehicle operation on surface roadways. The transporter vehicle and small electrically driven passenger vehicles are adapted to operate combined on, or independently use in common, traffic arteries such as highways or expressways and surface streets.

  • Patent number: 3933258
    Abstract: A vehicular transportation system and apparatus therefor is disclosed herein wherein small electrically driven passenger vehicles are carried as a group in a transporter or carrier vehicle. Extendable ramps are carried on the transporter vehicle which may be deployed from either end of the vehicle body for loading and unloading the passenger vehicles along a pair of parallel storage decks. Locking mechanism selectively secures each passenger vehicle in a storage space on the transporter vehicle while a separate conduit system for conducting conditioned air to the stored passenger vehicle is provided between the roof of the passenger vehicle and the transporter vehicle body. The transporter vehicle and electrically driven passenger vehicles are adapted to operate as a combined unit, substantially reducing fuel consumption, air pollution, and congestion, or independently as separate elements, on traffic arteries such as highways or expressways or surface streets.
