Abstract
Abstract A novel ski apparatus is disclosed wherein both of a skier's boots may be movably supported and accommodated on a single ski. Support means are rigidly secured to the ski and a pair of side-by-side, relatively slidable plate means are mounted on the support means. A heel and toe clamp assembly is secured to each plate means and each of the assemblies is longitudinally movable together with its associated plate means so that the skier may selectively advance one or the other boot relative to the remaining boot in accordance with the skiing requirements at a particular time, such as traverse situations. The plate means are retained in and guided by channel-type means that assure their free and accurate sliding movement and means are also provided for limiting the longitudinal movement of the plate means and, therefore, the skier's boots.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
196 words
Skiing apparatus comprising: an elongated ski assembly including a base ski, having a width dimension sufficient to accommodate both the skier's boots thereon at the same time; support means carried by said ski; a pair of plate means carried in substantially side-by-side relationship by said support means and which are relatively slidable with respect thereto; means for mounting a heel and top clamp assembly for a ski boot on each said plate means whereby the heel and toe clamp assemblies are independently and selectively movable longitudinally relative to the length dimension of said ski together with said associated plate means and the ski boots clamped by said assemblies; and guide means for retaining said plate means during the movement thereof, said guide means comprising a groove formed in the surface of each said plate means that is in confronting opposition to upper surfaces of said ski assembly, and said support means comprising a pair of longitudinally extending, elongated side-by-side members having upper and lower ends and a connecting web, said upper ends of said members being received in said slots in said plate means, said lower ends of said side-by-side members being carried by the ski.
Claim 2
Dependent Claim
196 words
Skiing apparatus comprising: an elongated ski assembly including a base ski, having a width dimension sufficient to accommodate both the skier's boots thereon at the same time; support means carried by said ski; a pair of plate means carried in substantially side-by-side relationship by said support means and which are relatively slidable with respect thereto; means for mounting a heel and top clamp assembly for a ski boot on each said plate means whereby the heel and toe clamp assemblies are independently and selectively movable longitudinally relative to the length dimension of said ski together with said associated plate means and the ski boots clamped by said assemblies; and guide means for retaining said plate means during the movement thereof, said guide means comprising a groove formed in the surface of each said plate means that is in confronting opposition to upper surfaces of said ski assembly, and said support means comprising a pair of longitudinally extending, elongated side-by-side members having upper and lower ends and a connecting web, said upper ends of said members being received in said slots in said plate means, said lower ends of said side-by-side members being carried by the ski.
Claim 3
Dependent Claim
17 words
A ski apparatus according to claim 1 wherein said slots are T-shaped and said members are T-shaped.
Claim 4
Dependent Claim
19 words
A ski apparatus according to claim 1 wherein lower flanges of said I-shaped members are embedded within said ski.
Claim 5
Dependent Claim
176 words
Skiing apparatus comprising: an elongated ski assembly including a base ski having a width dimension sufficient to accommodate both the skier's boots thereon at the same time; support means carried by said ski, said support means comprising a transverse base wall secured to said ski, column means integral with said base wall and extending upwardly above the top surface of said ski and a platform integral with the upper end of said column means, a pair of plate means carried in substantially side-by-side relationship by said support means and which are relatively slidable with respect thereto; means for mounting a heel and toe clamp assembly for a ski boot on each said plate means whereby the heel and toe clamp assemblies are independently and selectively movable longitudinally relative to the length dimension of said ski together with said associated plate means and the ski boots clamped by said assemblies; and guide means for retaining said plate means during the movement thereof, said guide means comprising a pair of grooves formed in the surface of said platform.
Claim 6
Dependent Claim
