Abstract
Abstract A snow ski exercising and training apparatus including a base upon which is mounted a pair of elongated ski simulating members, the forward ends of which are pivotally secured to the base so that the ski members can be pivotally moved transversely of the base about axes at their forward ends. Adjacent their rear ends, the skis are supported by a transversely extending slide bar for the transverse movement. A spring couples the skis together adjacent the forward ends to urge the same rotatably outward with respect to one another about their longitudinal axes, and tension springs couple each of the ski members to the base to provide resilient resistance to the transverse movement. A waistband is provided for the user and tension springs are used for attaching the waistband to the rearwardly ends of the ski members.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
133 words
A ski exercising and training apparatus comprising a base, a pair of adjacent elongAted ski representing members mounted on said base with their forward ends pivotally secured thereto for pivotal movement of said members transversely relative to said base, a transversely extending slide member located rearwardly of said forward ends and said ski members being supported thereon for said movement, bindings on said ski representing members for securing the feet of a user thereto, spring means coupling each of said ski members to said base rearwardly of said forward ends to provide resilient resistance to said transverse movement of said ski members relative to said base, a waistband for securance about a waist of a user, and tension spring means securing said waistband to each of said ski members rearwardly of said bindings.
Claim 2
Dependent Claim
133 words
A ski exercising and training apparatus comprising a base, a pair of adjacent elongAted ski representing members mounted on said base with their forward ends pivotally secured thereto for pivotal movement of said members transversely relative to said base, a transversely extending slide member located rearwardly of said forward ends and said ski members being supported thereon for said movement, bindings on said ski representing members for securing the feet of a user thereto, spring means coupling each of said ski members to said base rearwardly of said forward ends to provide resilient resistance to said transverse movement of said ski members relative to said base, a waistband for securance about a waist of a user, and tension spring means securing said waistband to each of said ski members rearwardly of said bindings.
Claim 3
Dependent Claim
74 words
The ski exercising and training apparatus of claim 1 wherein the forward end of each of said elongated ski members is pivotally secured to said base for rotational motion generally about its own longitudinal axis in addition to said pivotal movement transversely of said base, and wherein spring means is provided resiliently urging rotation of each of said ski members about its own longitudinal axis in a direction outward with respect to one another.
Claim 4
Dependent Claim
54 words
The ski exercising and training apparatus of claim 2 wherein the bottom surface of each of said ski members at the point of its support by said slide member is generally convex to facilitate said motion about its own axis and includes an insert of a low friction material to facilitate said pivotal movement.
Claim 5
Dependent Claim
55 words
The ski exercising and training apparatus of claim 3 wherein said ski members are mounted on said base at a forwardly sloping incline relative thereto, the height of said transversely extending slide member being selectively adjustable to permit variation in the angle of inclination at which said ski members are supported by said slide member.
Claim 6
Dependent Claim
135 words
A ski exercising and training apparatus comprising a base, a pair of adjacent elongated ski representing members mounted on said base with their forward ends pivotally secured thereto for pivotal movement of said members transversely relative to said base, a transversely extending slide member located rearwardly of said forward ends and said ski members being supported thereon for said movement, bindings on said ski representing members for securing the feet of a user thereto, the forward end of each of said elongated ski members being pivotally secured to said base for rotational motion generally about its own longitudinal axis in addition to said pivotal movement transversely of said base, and spring means resiliently urging rotation of each of said ski members about its own longitudinal axis in a direction outward with respect to one another.
Claim 7
Dependent Claim
135 words
A ski exercising and training apparatus comprising a base, a pair of adjacent elongated ski representing members mounted on said base with their forward ends pivotally secured thereto for pivotal movement of said members transversely relative to said base, a transversely extending slide member located rearwardly of said forward ends and said ski members being supported thereon for said movement, bindings on said ski representing members for securing the feet of a user thereto, the forward end of each of said elongated ski members being pivotally secured to said base for rotational motion generally about its own longitudinal axis in addition to said pivotal movement transversely of said base, and spring means resiliently urging rotation of each of said ski members about its own longitudinal axis in a direction outward with respect to one another.
Claim 8
Dependent Claim
40 words
The ski exercising and training apparatus of claim 5 wherein the bottom surface of each of said ski members at the point of its support by said slide member is generally convex to facilitate said motion about its own axis.
Claim 9
Dependent Claim
121 words
A ski exercising and training apparatus comprising a base, a pair of adjacent elongated ski representing members pivotally mounted adjacent the forward ends thereof on said base for pivotal movement with respect thereto in transverse directions, means supporting said ski members adjacent their rear end portions accommodating said pivotal movement thereof, means operative between said base and ski members for resisting such transverse movement of said ski members, said ski members also being supported with respect to said base for rotational motion with respect thereto generally about their respective longitudinal axes and spring means urging each of said ski members toward a predetermined rotational orientation about its longitudinal axis to bias said ski members toward such predetermined position of rotational orientation.
Claim 10
Dependent Claim
121 words
A ski exercising and training apparatus comprising a base, a pair of adjacent elongated ski representing members pivotally mounted adjacent the forward ends thereof on said base for pivotal movement with respect thereto in transverse directions, means supporting said ski members adjacent their rear end portions accommodating said pivotal movement thereof, means operative between said base and ski members for resisting such transverse movement of said ski members, said ski members also being supported with respect to said base for rotational motion with respect thereto generally about their respective longitudinal axes and spring means urging each of said ski members toward a predetermined rotational orientation about its longitudinal axis to bias said ski members toward such predetermined position of rotational orientation.
Claim 11
Dependent Claim
45 words
The ski exercising and training apparatus of claim 7 and further comprising a waistband for securance about the waist of one standing upon said ski members, and tension spring means securing said waistband to each of said ski membErs adjacent the rear end portions thereof.
Claim 12
Dependent Claim
54 words
The ski exercising and training apparatus of claim 7 in which the aforesaid means supporting said ski members adjacent the rear end portions thereof enforce a forwardly sloping incline thereon relative to said base, and further comprising bindings on said ski members intermediate the end portions thereof for securing the feet of user thereto.
Claim 13
Dependent Claim
77 words
The ski exercising and training apparatus of claim 9 in which the aforesaid means for supporting said ski members adjacent the rear end portions thereof includes a transversely extending slide member receiving and supporting said ski members thereon, and in which the bottom surface of each of said ski members along the area of its engagement with said slide member is generally convex to facilitate the aforesaid rotational motion of said ski members about their longitudinal axes.
