Ski attachment

Ski attachment, comprising:

• (a) a rectangular base plate adapted to be fastened to the upper surface of a ski and having a track at each transverse end, each of said tracks consisting of a vertical end wall and a flange extending horizontally and inwardly from the upper edge of the vertical wall,
• (b) a generally rectangular movable plate extending between the said end walls and fitting snugly under the flanges for sliding movement transversely of the ski between an operative position and an inoperative position, said movable plate having a width which is a selected amount less than the width of the ski,
• (c) a pawl having a thickness in the transverse direction of the ski which is generally equal to said selected amount, one end of said pawl being mounted on the movable plate for pivotal movement about a horizontal axis adjacent the forward end of the base, and the other end of the pawl lying over the base plate and under the flange of the rearward flange when the movable plate is in the inoperative position, so that the pawl is prevented from pivoting about said horizontal axis, said pawl lying outside of the ski and the rearward flange when the movable plate is in the operative position, so that the pawl is free to pivot about said horizontal axis,
• (d) a detent for selectively locking the movable element against transverse sliding in either said inoperative position or said operative position, and
• (e) means for biasing said other end of the pawl against the base plate when the movable plate is in said inoperative position and for biasing said other end against the ground when the movable plate is in said operative position.
