Quick-release skis couple to the front wheels of an ATV or other wheeled vehicle, to permit the ATV to travel over snow. The rear ATV wheels may be left unaltered, or more commonly, tracks may be substituted for the rear wheels. The ski coupling includes a drive-on runner and coupling having in one embodiment width-adjustable side walls, an over-center clamp, and a lock for securing the over-center clamp. In a second embodiment, a pivotal tire cage allows the ATV tire to be driven onto the ski, but simply by forward travel of the tire pivots to constrain the tire thereon. A strap then binds the tire and cage to ensure the tire stays in place on the ski. In a third embodiment, an ATV track is converted to a runner by the application and tensioning of a ski.
A quick-release ATV ski, comprising:
In combination, a ski-shaped wheel support, at least one support arm extending normal to said ski-shaped wheel support, a pivotal wheel cage pivotally supported upon said support arm and pivotal from a first wheel loading position having a first edge of said pivotal wheel cage adjacent to said ski-shaped wheel support and a second edge distal to said first edge spaced from said ski-shaped wheel support, to a second wheel retaining position having said first and second edges of said pivotal wheel cage approximately equidistant from said ski-shaped wheel support.
In combination, an ATV endless track uncoupled from a rotary drive, a ski, and a tensioning member retaining said ski between said ATV track and a ground surface.
