ABSTRACT:
A ski construction in which the ski runner slidingly supports an elongated plate, except at its adjustable front end which is fixed in normal use of the ski, the plate carrying toe and heel binding members, the plate being specially mounted to freely follow the runner in its rapid bending movements in use of the ski, and also adapted to alievate the stress and shock imposed on the ankle area of the skier when the front of the ski strikes an obstruction and the ski abruptly stops, as by striking a root obstruction, a body of hard ice hidden by snow, or packed snow, and this aliveation without changing the action of the binding members or their mutual set-spacing on the plate. For the latter function, the front end of the plate carries a row of teeth engaged by a worm carried by a shaft within a casing fixed to the runner, one end of the shaft having means for its manual rotation for adjustment of the plate, and a spring encircling the shaft and having its front end abutting the interior of the casing, so that when the ski is suddenly stopped by an obstruction, the forward strong thrust of the skier's leg moves the entire plate forwardly against the action of said spring, alievating shock on the ankle area.
