Abstract
Abstract A skier's exercise device includes an inclined platform supporting a baseplate having four retaining walls within which a turntable is rotatably mounted. The turntable is formed with a pair of parallel spaced troughs adapted to rotatably receive a pair of support members. Each support member slidably receives a foot plate equipped with foot straps releasably securing the user's feet to the plates. Each of four retaining walls is formed with a slot adapted to receive the friction pad to engage the edge of the turntable to impede the rotation thereof.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
81 words
Skier's exercise apparatus including in combination a turntable formed with a pair of generally parallel spaced elongated troughs, means mounting said turntable for rotary movement around a pivot axis located between said troughs, a pair of intermediate supports, means mounting said supports in said troughs for rotary movement around axes extending generally longitudinally of said troughs, a pair of foot-receiving plates, and means mounting said plates respectively on said supports for fore-and-aft sliding movement in the direction of said support axes.
Claim 2
Dependent Claim
81 words
Skier's exercise apparatus including in combination a turntable formed with a pair of generally parallel spaced elongated troughs, means mounting said turntable for rotary movement around a pivot axis located between said troughs, a pair of intermediate supports, means mounting said supports in said troughs for rotary movement around axes extending generally longitudinally of said troughs, a pair of foot-receiving plates, and means mounting said plates respectively on said supports for fore-and-aft sliding movement in the direction of said support axes.
Claim 3
Dependent Claim
100 words
Skier's exercise apparatus including in combination a base formed with a generally circular recess, a generally circular turntable formed with a pair of generally parallel spaced elongated troughs, means mounting said turntable in said recess for rotary movement around a pivot axis located between said troughs, a pair of intermediate supports, means mounting said supports in said troughs for rotary movement around respective axes extending generally in the direction of the lengths of said troughs, a pair of foot-receiving plates, and means mounting said plates respectively on said supports for fore-and-aft sliding movement in the direction of said support axes.
Claim 4
Dependent Claim
