  • Publication number: 20080084037
    Abstract: A collapsible trailer and method for use of the same are disclosed. In one embodiment, the collapsible trailer includes a jointed lattice-work frame of scissor linkages which in the expanded position provide an open enclosure for transporting the load. Two orthogonally positioned collapsible crossbars span the open enclosure and releasably engage the lattice-work frame. A meshed netting is superposed to the collapsible crossbars and releasably coupled to the lattice-work frame. The collapsible trailer may be configured in a collapsed position for easy storage when not in use by removing the meshed netting, releasing the collapsible crossbars, and slidably collapsing the collapsible crossbars lengthwise and width wise in an accordion fashion.

  • Patent number: 6164674
    Abstract: A multi-wheeled vehicle having adjustable wheelbase dimensions. The preferred embodiment is a wheelchair which affords on-the-fly adjustment of width. The linkage between the two side frames of the present wheelchair is of two cross members in a horizontal X configuration, one end of each cross member being pivotally affixed to one side frame on one side of the wheelchair, with the respective other end of each cross member being slidably engaged with the opposite side frame. The cross members are pivotally attached to each other at a point of intersection. This structure allows a wheelchair of the present design to be easily expanded and contracted in width during use, with the rider in-place, and avoids the necessity of incremental changes between uses, such as is required by wheelchairs of present design. Yet, such a wheelchair is structurally quite stable with respect to any tendency of the side frames to toe-in under torque applied by weight on the seat.

  • Patent number: 5857684
    Abstract: A first frame member and a second frame member are pivotally joined at respective ends thereof for movement towards each other into a collapsed disposition and for movement away from each other into an erected condition wherein the members are at right angles to each other. One of the members supports to each of its sides an articulating wheel support and wheel and carries within its hollow a slide which is connected by pivots to each of said wheel supports and by pivoting straps to the other frame member so that when the frame members pivot apart the wheels move out and so that when the frame members pivot towards each other the wheels are drawn in so that the entire device assumes a collapsed condition. The frame members carry supports for a golf bag and may carry a battery tank (for a battery when the wheels are driven by motors that are battery powered) storage containers, seats, an umbrella stand and similar articles useful to a golfer. A number of wheel support configurations are provided.

  • Patent number: 5845922
    Abstract: A tow bar connecting a towed vehicle a towing vehicle has a shaft forking to tines whose hooks to engage the axle or undercarriage of the towed vehicle. A cradle or bracket slidable on the shaft engages the frame, bumper or other part of the towed vehicle. An arm is pivoted to the shaft by the arm's disk-like termini, which rotatingly sandwich the shaft's disk-like terminus. The arm's termini have satellite apertures which register with complementary satellite apertures in the shaft's terminus. Registering of the respective satellite apertures occurs at selected relative angular portions of the arm and shaft. Pins through the registered satellite apertures lock the arm and shaft in a given relative angular position. A jack raises the shaft once the tow bar is on the towed vehicle. The tow bar includes an eye or the like for attaching the tow bar to the hitch of the towing vehicle.
