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 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.

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 operatively preventing said over-center clamp from rotating and thereby preventing accidental release of said over-center clamp, said removable lock comprising:
an over-center clamp actuator that rotates about an over-center clamp actuator axis to operatively alternatively tension and release tension on said strap;a side wall on each one of said pair of wheel receivers rising generally perpendicularly from said ski-shaped wheel support and spaced from each other to operatively receive a wheel there between; anda pin operatively extending parallel with said over-center clamp actuator axis and operatively engaged with said over-center clamp, thereby preventing rotation of said over-center clamp actuator when said pin is operative, and removable therefrom to enable rotation of said over-center clamp actuator.
