  • Patent number: 5193836
    Abstract: Intermodal transport of the removably attached combination of an underlying drayable chassis with an immediately overlying cargo-carrying container having a forward-end and a rearward-end. In conventional fashion, the container adjacent its forward-end is removably attached to a frontal portion of the drayable chassis. Departing from the prior art, the cargo-carrying container, at a prescribed rearward-length separation from its rearward-end, is removably attached to a single set of transversely aligned plural chassis rear-lock stations. Thus, the container rearward-length extends unconventionally cantileverly rearwardly from and might overlie the container's rearmost attachment station to the underlying drayable chassis.

  • Patent number: 4685691
    Abstract: This trailer comprises a U-shape load-carrying casing with a hitching bar across the free ends of the legs of the casing. The center of said cross-bar is hitched to the vehicle between the two wheels thereof by means of a universal joint hitch. The load carrying casing extends on both sides of the vehicle and across the back thereof. Two wheels support the back of the casing. The universal hitch enables the vehicle, such as a motorcycle, to roll, rotate or pitch relative to the trailer, such as when taking curves and/or riding on bumpy roads of grade and down-grade. The hitch is positioned below the horizontal plane passing through the vehicle axles and in front of the center of gravity of the vehicle. The trailer and vehicle assembly is very stable both while riding and braking. Also, the portions of the casing extending on both sides of the vehicle constitute a protection for the vehicle rider and passenger.

  • Patent number: 4664401
    Abstract: A boat trailer frame is described including an adjustable pair of elongated frame members extending from a tongue section to a wheel supported carriage. Bunks are mounted directly to the frame members. Forward ends of the frame members are pivotably mounted to the tongue and selectively clamped to the wheel carriage. Lateral adjustment of the distance between the frame members and bunks is provided to accommodate boat hulls of varying configurations. Such lateral adjustment is accomplished simply by pivoting the frame members together or apart about the forward pivots at the tongue. Clamps are included for selectively securing the frame members to the carriage assembly and tongue once a selected space between the bunks is achieved. Other clamps are used to facilitate longitudinal adjustment of the wheel carriage position along the frame members to adjust "tongue weight".
