Abstract
A ski attachment for a free-turning vehicle wheel consisting of one or more skis, rigidly joined if more than one, adapted to be placed beneath the wheel in line therewith, a cradle carried on the top of the ski, to the rear of center thereof, and configurated to receive and support the lower portion of the tire of the wheel, and tension devices for drawing the cradle into indenting relation to the tire. The tension devices may consist of connectors joining the cradle to the wheel axle at each side of the wheel, or of steel straps surrounding tire peripherally and joined at their ends to the cradle. A special ski bottom configuration assists in preventing lateral slipping or skidding in turns.
Claims5
A ski attachment for a non-driven, free-turning vehicle wheel having a compressible tire, said attachment comprising:
- a. a ski having a substantially straight rear portion and an upwardly curved front portion, and adapted to be positioned beneath said wheel parallel to the line of travel thereof,
- b. a rigid cradle member affixed to the top surface of said straight rear ski portion, the top of said cradle member being configurated to receive and support the lower portion of said tire therein, and
- c. tension means detachably interconnecting said cradle member with an axle of said wheel, and manually operable to draw said cradle member into compressing engagement with said tire, whereby said ski is held in substantially fixed relation to said tire, said tension means comprising:
- (1) a pair of straps secured at their lower ends to said cradle member respectively adjacent the forward and rearward ends of the latter, and converging upwardly in a plane parallel to the plane of the wheel, there being a pair of said straps at each of the respectively opposite sides of the cradle,
- (2) a plate secured to the upper ends of each of said pairs of straps,
- (3) a pair of hooks disposed at the respectively opposite sides of said tire, each detachably engageable at its upper end over the axle of said wheel, and extending downwardly therefrom, and
- (4) a toggle link interconnecting each of said plates to the lower end of the associated hook and manually operable both to extend said hook upwardly when open, and to retract said hook downwardly when closed, and to lock said hook releasably in said retracted position.
