Claim 3

A monoski according to claim 1 wherein the lower ski boot binding means comprises heel binding means mounted on the rear platform support.

Claim 4

A monoski according to claim 2 wherein the heel binding means comprises a heel slide mounted on the rear platform support for longitudinal reciprocable movement, spring means forwardly biasing the slide to a forward operative position and permitting rearward retraction of the slide, the slide having a forward end providing a step-in and step-out heel connector for step-in attachment and step-out removal of the monoski at said lower position.

Claim 5

A monoski according to claim 3 wherein the heel binding means comprises means for adjusting the forward bias of the spring means on the heel slide to vary the force required for said step-in attachment and step-out removal of the monoski at said lower position.

Claim 6

A monoski according to claim 1 wherein the upper ski boot binding means provides for attachment to a pair of ski boots in side-by-side association generally centered over the longitudinal axis of the ski and the lower ski boot binding means provides for attachment to a single ski boot at said alternative lower position generally centered over the longitudinal axis of the ski.

Claim 7

A monoski according to claim 1 wherein the platform support mounting means comprises a longitudinally extending guideway affixed to the ski and a slide longitudinally reciprocable in the guideway and forming the base of said one platform support for longitudinally adjusting it along the ski, and locking means for selectively locking said one platform support at Each of a plurality of longitudinally spaced positions along the guideway.

Claim 8

A monoski according to claim 6 wherein the locking means comprises a plurality of longitudinally spaced locking abutments on the guideway, a locking member mounted on said one platform support operable for selective engagement with the longitudinally spaced locking abutments for locking said one platform support against longitudinal displacement on the ski in each of a plurality of longitudinally spaced positions respectively, and manually operable means for operating the locking member.

Claim 9

A monoski according to claim 1 further comprising a stabilizer having a transversely extending cantilever support mounted on the ski rearwardly of the rear platform support and extending in both lateral directions beyond the ski and longitudinally extending outrigger edges depending from the cantilever support laterally outwardly of the opposite lateral edges of the ski, the cantilever support being resilient to permit the outrigger edges to be displaced upwardly during edging.

Claim 10

A monoski comprising an elongated ski with a lower longitudinally extending running surface and longitudinally extending control edges along opposite edges of the running surface, a platform assembly mounted generally centrally on the ski providing a raised platform above the ski and having ski boot binding means for supporting a monoskier on the raised platform at an elevated position above the lower running surface of the ski for monoskiing, and a stabilizer mounted on the ski substantially rearwardly of the raised platform comprising a transversely extending cantilever support mounted on the ski and extending in both lateral directions beyond the ski, and an outrigger edge member depending from the cantilever support on each side of the ski and having a lower longitudinally extending outrigger edge laterally outwardly of and raised above the adjacent lower running surface and side edge of the ski, the cantilever support being resilient to permit each outrigger edge member to be displaced upwardly when the monoski is inclined for edging to provide an auxiliary control edge for preventing overturns without nullifying the edging effectiveness of the adjacent control edge along the edge of the running surface of the ski.

Claim 11

A monoski comprising an elongated ski with a lower longitudinally extending running surface and longitudinally extending control edges along opposite edges of the running surface, a platform assembly mounted generally centrally on the ski providing a raised platform above the ski and having ski boot binding means for supporting a monoskier on the raised platform at an elevated position above the lower running surface of the ski for monoskiing, and a stabilizer mounted on the ski substantially rearwardly of the raised platform comprising a transversely extending cantilever support mounted on the ski and extending in both lateral directions beyond the ski, and an outrigger edge member depending from the cantilever support on each side of the ski and having a lower longitudinally extending outrigger edge laterally outwardly of and raised above the adjacent lower running surface and side edge of the ski, the cantilever support being resilient to permit each outrigger edge member to be displaced upwardly when the monoski is inclined for edging to provide an auxiliary control edge for preventing overturns without nullifying the edging effectiveness of the adjacent control edge along the edge of the running surface of the ski.

Claim 12

A ski assembly according to claim 9 wherein the cantilever support comprises a resilient transversely extending cantilever base supporting the depending outrigger edges and transversely extending leaf spring means overlying the cantilever base to control the upward displacement of the outrigger edges.

Claim 13

In a monoski comprising an elongated ski with a lower running surface and a platform assembly with forward and rear longitudinally spaced platform supports mounted on the ski respectively having forward and rear upper platform sections collectively providing a raised platform above the ski, and ski boot binding means for selectively supporting a skier on the raised platform, the improvement wherein the platform assembly is settable at a first setting for supporting a skier at an elevated position on the raised platform and alternatively settable at a second setting for supporting a skier at an alternative lower position below the raised platform and between the forward and rear platform supports, and wherein the ski boot binding means provides for attachment of the monoski to a pair of ski boots in side-by-side association on the raised platform and generally centered over the longitudinal axis of the ski with the platform assembly at said first setting and for attachment of the monoski to a single ski boot at said alternative lower position generally centered over the longitudinal axis of the ski with the platform assembly at said second setting.

Claim 14

In a monoski comprising an elongated ski with a lower running surface and a platform assembly with forward and rear longitudinally spaced platform supports mounted on the ski respectively having forward and rear upper platform sections collectively providing a raised platform above the ski, and ski boot binding means for selectively supporting a skier on the raised platform, the improvement wherein the platform assembly is settable at a first setting for supporting a skier at an elevated position on the raised platform and alternatively settable at a second setting for supporting a skier at an alternative lower position below the raised platform and between the forward and rear platform supports, and wherein the ski boot binding means provides for attachment of the monoski to a pair of ski boots in side-by-side association on the raised platform and generally centered over the longitudinal axis of the ski with the platform assembly at said first setting and for attachment of the monoski to a single ski boot at said alternative lower position generally centered over the longitudinal axis of the ski with the platform assembly at said second setting.
