ABSTRACT:
To arrest a ski runner upon its release from the skier's boot, two spurs are pivoted to a lateral face of the runner and are coupled together for joint rotation in opposite directions. A treadle rigid with or otherwise secured to one or both spurs overlies the upper runner surface in the region of the skier's boot so as to be depressed onto that surface when the boot is tied to the runner, thereby elevating the spurs into an aligned position alongside the runner against a spring force which may be that of an elastic part of the treadle. Upon detachment of the boot from the runner, the spring force swings the spurs downwardly and toward each other whereby their points bite into the snow at opposite angles. The pair of spurs may be duplicated on opposite sides of the runner for increased effectiveness.
