Abstract
Abstract Ski-simulator training apparatus including a track supporting a carriage for to and fro powered motion resultant from frictional contact with one or the other of oppositely moving flights of a continuously moving power driven endless belt which contact is automatically established by turning or canting motion of a pair of foot pads supported on the carriage and adapted to receive the feet of a ski trainee.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
109 words
Ski-simulator training apparatus which comprises a track adapted for support on a floor or other surface and defining a line, a carriage supported for movement on said track a pair of foot pads supported on said carriage for pivotal canting and turning motion about axes which are mutually perpendicular to one another and to the line defined by said track, powered members continuously moving in opposite directions along lines substantially parallel to the line of said track, and means automatically operative in response to pivotal motion of said foot pads for connecting said carriage to one of said powered members to effect movement of said carriage along said track.
Claim 2
Dependent Claim
109 words
Ski-simulator training apparatus which comprises a track adapted for support on a floor or other surface and defining a line, a carriage supported for movement on said track a pair of foot pads supported on said carriage for pivotal canting and turning motion about axes which are mutually perpendicular to one another and to the line defined by said track, powered members continuously moving in opposite directions along lines substantially parallel to the line of said track, and means automatically operative in response to pivotal motion of said foot pads for connecting said carriage to one of said powered members to effect movement of said carriage along said track.
Claim 3
Dependent Claim
30 words
Ski-simulator training apparatus according to claim 1 wherein said powered members are formed by parallel oppositelymoving flights of an endless belt mounted on pulleys at opposite extremities of said track.
Claim 4
Dependent Claim
58 words
Ski-simulator training apparatus according to claim 2 wherein said automatically operative connecting means establishes frictional connection with one flight of said endless belt in response to canting, pivotal motion of said foot pads in one direction and with the other flight of said belt in response to canting pivotal motion of said foot pads in the opposite direction.
Claim 5
Dependent Claim
56 words
Ski-simulator training apparatus according to claim 2 wherein said automatically operative connecting means establishes frictional connection with one flight of said endless belt in response to turning motion of said foot pads in one direction and with the other flight of said belt in response to turning motion of said foot pads in the opposite direction.
Claim 6
Dependent Claim
18 words
Ski-simulator training apparatus according to claim 2 which comprises means for varying the speed of said endless belt.
