A snow ski is provided including generally flat toe and heel sections and an arched center section extending between and interconnecting the toe and heel sections. The opposite side marginal edges of the bottom of the ski define snow biting edges for biting into an underlying snow surface when the ski is angularly displaced about its longitudinal axis relative to the snow surface and an intermediate length portion, only, of the snow biting edges extending along the heel section are modified to effectively reduce the capability thereof to bite into an underlying snow surface while the snow biting edges of the toe section of the ski are modified to increase the capability thereof to bite into the underlying snow surface. Further, the ski includes a predetermined toe binding area mounting location thereon spaced appreciably forward of the longitudinal mid-point of the ski, these features enabling elementary and intermediate level skiers to more readily "pin" the toe section of the ski when executing turns and allowing the heel section to controllably drift outward during the execution of a turn.
A snow ski designed to increase the proficiency of elementary and intermediate level skiers and to enable these levels of skiers to execute turns in various snow surface conditions with greater control and confidence and to also function to create a drag on the associated snow surface for retarding the speed of said ski, said ski including an elongated body defining a center longitudinal axis and incorporating an elongated and longitudinally extending forward toe section having a substantially flat lower surface, an elongated and longitudinally extending heel section having a substantially flat lower surface, an elongated and longitudinally extending arched center section extending between and interconnecting said toe and heel sections and an upwardly curving tip extending forward from the forward end of said toe section, said body including generally parallel upper and lower surfaces interconnected by opposite side surfaces extending therebetween, said opposite side surfaces being generally parallel throughout at least said center and heel sections, said side surfaces and said lower surfaces, at their respective points of intersection, forming opposite edges for biting into and underlying snow surface, by one of said edges, when said body is angularly displaced about its center longitudinal axis thereby raising the opposite edge relative to said snow surface, at least one of said side surfaces and the corresponding edge, in said toe section only, being outwardly bowed with the outwardly bowed portion, only, of said edge being serrated and with the serrations thereof flush with said bowed portion of said one side surface, said bowed portion of said one side surface and said serrated edge defining increased snow surface biting means effective to increase the capacity of the bowed portion of said one edge to bite into said snow surface over the capability of the remaining portion of said one opposite edge of said body to bite into said snow surface.
A snow ski designed to increase the proficiency of elementary and intermediate level skiers and to enable these levels of skiers to execute turns in various snow surface conditions with greater control and confidence and to also function to create a drag on the associated snow surface for retarding the speed of said ski, said ski including an elongated body defining a center longitudinal axis and incorporating an elongated and longitudinally extending forward tow section having a substantially flat lower surface, and elongated and longitudinally extending heel section having a substantially flat lower surface, an elongated and longitudinally extending arched center section extending between and interconnecting said toe and heel sections and an upwardly curving tip extending forward from the forward end of said toe section, said body including generally parallel upper and lower surfaces interconnected by opposite side surfaces extending therebetween, said opposite side surfaces being generally parallel throughout at least said center and heel sections, said side surfaces and said lower surfaces, at their respective points of intersection, forming opposite edges for biting into and underlying snow surface, by one of said edges, when said body is angularly displaced about its center longitudinal axis thereby raising the opposite edge relative to said snow surface, said toe sections, only, including an attachment secured over said toe section from thereabove and including a depending portion extending downwardly over said one side surface of said toe section and terminating downwardly substantially flush with the portion of said lower surface extending along said toe section, said depending portion defining a single outwardly bowed portion of said one edge in said toe section only functioning as increased snow surface biting means effective to increase the capacity of the corresponding side of said toe section to bite into said snow surface over the capability of the remaining one of said edges to bite into said snow surface.
