Abstract
An anti-tip crossing device for skis adapted to be mounted on the front upper surface of a ski comprising a hollow triangular shaped object having a curved surface adjacent to the outer edge of the ski and a substantially perpendicular surface adjacent the inner edge of the ski, the entire object being detachably mounted for easy removal when desired; this device serving the purpose of preventing crossing of the tips of the skis in normal use and being shaped to permit skis when they are crossed to be redirected in their parallel alignment with the least resistance to that movement by the skier.

An anti-tip crossing device for skis adapted to be mounted on the front upper surface of a ski substantially perpendicular thereto, comprising a generally triangular annulus made of resilient plastic and having two upstanding sides and a base completely encircling a central open space except for a gap in the middle of said base, said base being positioned transversely across substantially the entire width of said ski, a first side of said annulus adjacent the inner edge of said ski extending substantially perpendicularly from the upper surface of the ski at its inner edge to an apex, a second side of said annulus extending from the upper surface of the ski at its outer edge to said apex in convexly arcuate shape, said annulus being detachably mounted to the upper surface of the ski by means of a base plate fixed to the upper surface of the ski and positioned transversely thereof, said base plate comprising two tubular portions aligned with each other and spaced apart from each other near the center of the ski, said base of said annulus comprising two separate prongs joined respectively to said first side and said second side and projecting toward each other, the cross-section of each prong being substantially the same size and shape as the cross-section of said tubular portions of said base plate except for a flange member at the free end of each prong which is sufficiently larger than said cross-section so as to be insertable when compressed into the tubular portion and to expand to the uncompressed state in the central space between said tubular portions to form a tight fastening of the flange member to said base plate.
A ski to which is detachably mounted an anti-tip crossing device comprising a base plate fixed transversely to the front, upper surface of the ski and an upstanding generally triangular annulus made of resilient plastic and having two upstanding sides and a base completely encircling a central open space except for a gap in the middle of said base, said base being detachably mounted to said base plate comprising two aligned tubular portions spaced apart from each other near the center of the ski, said annulus having a first side extending from the upper surface of said ski at its inner edge in a substantially perpendicular direction to an apex, a second side extending from the upper surface of said ski at its outer edge in a convexly arcuate direction to said apex, and said base comprising two separate prongs projecting toward each other respectively from said first and second sides, each prong having a cross section substantially the same size and shape as the cross section of said tubular portions except that at the terminal portion of each prong is a flange sufficiently larger in cross section than that of the tubular portions so as to be insertable in the tubular portion when compressed and to expand to the uncompressed state in the central space between said tubular portions to form a tight fastening of the flange member to said base plate.
