In combination, a ski runner, an elongated plate mounted on the ski runner, and bodily movable thereon, toe and heel boot binding members carried by said elongated plate, means for adjusting one of said boot binding members forwardly or rearwardly on said elongated plate, teeth carried at the front of the elongated plate, a worm engaging said teeth and manually operable means for rotating said worm, whereby said elongated plate may be adjusted forwardly and rearwardly on the ski runner, and comprising a shaft carrying the worm, a casing affixed to the ski runner and in which the shaft and worm are mounted, one end of the shaft being exposed with a head adapted for manual rotation of the shaft and worm, and a spring member within the casing and engaged by the worm and abutting the front wall of the casing, whereby, when the front end of the ski runner abuts an obstruction, the stress and shock imposed on the ankle area of the skier by its continued forward movement when held by the bindings is alievated by cushioned forward movement of the elongated plate, and without changing the distance between the toe and heel members, or releasing their boot holding action.

In combination, a ski runner, an elongated plate mounted on the ski runner, and bodily movable thereon, toe and heel boot binding members carried by said elongated plate, means for adjusting one of said boot binding members forwardly or rearwardly on said elongated plate, teeth carried at the front of the elongated plate, a worm engaging said teeth and manually operable means for rotating said worm, whereby said elongated plate may be adjusted forwardly and rearwardly on the ski runner, and comprising a shaft carrying the worm, a casing affixed to the ski runner and in which the shaft and worm are mounted, one end of the shaft being exposed with a head adapted for manual rotation of the shaft and worm, and a spring member within the casing and engaged by the worm and abutting the front wall of the casing, whereby, when the front end of the ski runner abuts an obstruction, the stress and shock imposed on the ankle area of the skier by its continued forward movement when held by the bindings is alievated by cushioned forward movement of the elongated plate, and without changing the distance between the toe and heel members, or releasing their boot holding action.
Claim 3
Dependent Claim

A ski construction in accordance with claim 1 in which the worm carries a screw-like shaft on which the spring is mounted, the casing for said worm being fastened at its sides to the margins of the ski runner, the casing having a rear aperture through which an extension of the screw-like shaft is projected, the front of the shaft being projected through a front aperture of the casing and the head thereof formed with means for its manual rotation, the elongated plate being formed with a longitudinal slot intermdiate the binding members, a bushing in said slot, a screw entering the bushing and engaging its top, whereby the screw is restricted against putting pressure on the top of the plate, the plate having a narrowed width at each end and also adjacent the rear of the toe binding member, said casing overlying the forward narrowed end, and two spaced strap members, each lying over one of said narrowed areas of the plate, and having their ends fasteded to the ski runner and guiding and holding down said plate in such manner that its smooth under surface meets the ski runner without pressure thereon and enabling the plate to follow rapid bends of the runner when the ski is in use and with consequent sliding movements of the plate rearwardly of its fixed front end area in normal use of the ski.
