Quick-Release ATV Skis

摘要

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 the cage 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. Additional embodiments are illustrated.

主权项

1. A quick-release ATV ski, comprising:
a ski-shaped wheel support; a pair of wheel receivers extending longitudinally along and rising from said ski-shaped wheel support and spaced laterally from each other to define a wheel cage; a strap anchor adjacent a first end of said wheel cage; an over-center clamp adjacent a second end of said wheel cage distal to said first end; a strap coupled between said strap anchor and said over-center clamp; and a removable lock positively engaging said over-center clamp and thereby preventing accidental release of said over-center clamp.
