Ski anti-crossing device

Abstract

A device for attachment to skis comprising a vertical member and a base plate on which said vertical member can move relative to the base plate. The vertical member may be springhinged to the base plate. The vertical member is preferably airfoil shaped.

What is claimed is: .[.1. Means for attachment to the upper surfaces adjacent an end of skis comprising a first base plate, mounted on a first ski, a first member pivotally mounted on said first base plate, 
     
        member..]. 2. Apparatus as in claim .[.1.]. .Iadd.7 .Iaddend.in which said 
     
     
        movable member is airfoil shaped. 3. Apparatus as in claim .[.1.]. .Iadd.7 .Iaddend.in which said base plate contains means such as slots for 
     
     
        reducing the stiffness of the base plate. 4. Apparatus as in claim .[.1.]. .Iadd.7 .Iaddend.in which means are provided for adjustment of said 
     
     
        attachment means relative to the ski. 5. Apparatus as in claim .[.1.]. .Iadd.7 .Iaddend.wherein said base plate is substantially wider at one end 
     
     
        than at the other for purposes of providing a torque arm. .Iadd.6.  Means for attachment to the upper surfaces adjacent an end of skis comprising a fist base plate, mounted on a first ski, a first member pivotally mounted on said first base plate, a second base plate mounted on a second ski, a second member pivotally mounted on said second base plate, said members being pivoted about an axis extending in the direction of the longitudinal axis of said skis,   said members being spring loaded to the vertical position, each said member being adapted to block the other ski from crossing it but yielding in the direction that will unblock the other ski if the other ski has crossed a   
     
     
        member. .Iaddend. .Iadd.7.  Means for attachment to the upper surfaces adjacent an end of skis comprising a first base plate, mounted on a first ski, a first member pivotally mounted on said first base plate, a second base plate mounted on a second ski, a second member pivotally mounted on said second base plate, said members being pivoted about an axis generally parallel to the upper surfaces of said skis and generally longitudinally thereof,   said members being spring loaded to the vertical position, each said member being adapted to block the other ski from crossing it but yielding in the direction that will unblock the other ski if the other ski has crossed a member..Iaddend.
