ABSTRACT:
A traction device for skis moves in response to forward and rearward thrusting motion of the ski to selectively engage the snow or ice surface to prevent rearward sliding motion of the ski and disengage to allow free forward sliding motion of the ski. The device is cammed between operative and inoperative position in response to the forward and rearward thrusting motions of the ski. A tooth arrangement can also be provided to swing between operative and inoperative positions similar to that of the traction member. The tooth device can also be pivoted to a position wherein the traction device is locked in an operative position. In this situation, the traction device operates continuously in forward as well as backward motions of the ski. The operative traction member acts in forward motion, as a braking device to slow forward progress.
