Abstract
Abstract Apparatus for use in exercising and toning muscles principally used in skiing includes a base having a supporting bottom with sides upwardly extending from a central apex about which the base is rockable between semi-stable positions. A pair of foot pedals rest atop the base within grooves parallel to each other and to the apex of the base of the block. The foot pedals are of generally triangular cross sectional shape to be rockable between semi-stable positions on the block. The foot pedals additionally are moveable forward and aft to simulate the foot positions of actual skiing.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
137 words
A device for simulating skiing conditions comprising: a base having a pair of V-shaped parallel grooves running front to back along a top surface thereof, a downward surface on said base tapered upwardly from a central longitudinal apex along a front to back axis of the base and about which said base can be rocked from side to side and, a pair of generally triangular cross-section foot pedals each locatable in a respective one of said parallel grooves with an angled portion thereof extending downwardly into said groove to support said foot pedal therewithin, and about which said foot pedal can be rocked from side to side independently of said base, whereby when a user stands on the foot pedals of said device, the user can rock the foot pedals and the block to simulate skiing conditions.
Claim 2
Independent Claim
137 words
A device for simulating skiing conditions comprising: a base having a pair of V-shaped parallel grooves running front to back along a top surface thereof, a downward surface on said base tapered upwardly from a central longitudinal apex along a front to back axis of the base and about which said base can be rocked from side to side and, a pair of generally triangular cross-section foot pedals each locatable in a respective one of said parallel grooves with an angled portion thereof extending downwardly into said groove to support said foot pedal therewithin, and about which said foot pedal can be rocked from side to side independently of said base, whereby when a user stands on the foot pedals of said device, the user can rock the foot pedals and the block to simulate skiing conditions.
Claim 3
Dependent Claim
37 words
The device of claim 1 wherein said angle portions which support said foot pedals are rounded and wherein bottoms of said parallel grooves are correspondingly rounded to receive said angled portion to facilitate smooth foot pedal rocking.
Claim 4
Dependent Claim
35 words
The device of claim 1 wherein said base has angles and height whereby its rocked position can only be maintained by distributing more than about 55% of the user's weight on a downhill foot pedal.
Claim 5
Dependent Claim
15 words
The device of claim 3 wherein said base is of height of approximately 5 inches.
Claim 6
Dependent Claim
53 words
The device of claim 1 wherein said support angled portion of each of said foot pedals is grooved concavely along at least a portion of its length and further comprising a convexly curved protrusion along the bottom of each of said V-shaped grooves upon which said foot pedals ride within said concave grooves.
Claim 7
Dependent Claim
34 words
The device of claim 1 wherein said foot pedals are slideable longitudinally within said V-shaped grooves, and further comprising means for limiting the forward and backward extent of the sliding of said foot pedals.
Claim 8
Dependent Claim
45 words
The device of claim 1 wherein said "V" shaped groove is grooved along its bottom and said support angled portion is grooved along its length and further comprising a spline within said grooves to prevent lateral slipping of said foot pedals in said V-shaped grooves.
Claim 9
Independent Claim
80 words
A device, comprising: two foot pedals of generally triangular cross-sectional shape, an apex of said shape being oriented downwardly, a block moveable between semi-stable side-to-side positions, having two parallel V-shaped grooves along a top surface to receive said foot plates, the angle between the walls of said V-shaped grooves being larger than the angle between the walls of said downwardly oriented apex of said foot pedals, whereby the foot pedals are rotatable from side-to-side about said apex within said grooves.
Claim 10
Independent Claim
80 words
A device, comprising: two foot pedals of generally triangular cross-sectional shape, an apex of said shape being oriented downwardly, a block moveable between semi-stable side-to-side positions, having two parallel V-shaped grooves along a top surface to receive said foot plates, the angle between the walls of said V-shaped grooves being larger than the angle between the walls of said downwardly oriented apex of said foot pedals, whereby the foot pedals are rotatable from side-to-side about said apex within said grooves.
Claim 11
Dependent Claim
20 words
The device of claim 8 further comprising bearing means between said block within said V-shaped grooves and said foot pedals.
Claim 12
Dependent Claim
13 words
The device of claim 9 wherein said bearing means are curved mating surfaces.
Claim 13
Dependent Claim
32 words
The device of claim 10 wherein said curved mating surfaces are a concave surface along the apex of said foot pedals and a convex surface along the base of said V-shaped grooves.
Claim 14
Dependent Claim
32 words
The device of claim 10 wherein said curved mating surface are a convex surface along the apex of said foot pedals and a concave surface along the bottom of said V-shaped grooves.
Claim 15
Dependent Claim
41 words
The device of claim 8 wherein said block is formed with a base having a central apex parallel to said V-shaped grooves from which the bottom sides rise to define semi-stable positions of said block on each side of said apex.
Claim 16
Dependent Claim
14 words
The device of claim 8 further comprising means for facilitating rotation of said base.
Claim 17
Dependent Claim
70 words
Apparatus for simulating ski conditions, comprising: a pair of foot pedals, each of generally triangular cross-sectional shape, a base, said base having a top having a pair of front to back parallel V-shaped grooves for receiving said foot pedals, whereby said foot pedals are rotatable from side to side within said grooves, said base having an unstable supporting surface whereby said base is rotatable from side-to-side upon said supporting surface.
Claim 18
Dependent Claim
70 words
Apparatus for simulating ski conditions, comprising: a pair of foot pedals, each of generally triangular cross-sectional shape, a base, said base having a top having a pair of front to back parallel V-shaped grooves for receiving said foot pedals, whereby said foot pedals are rotatable from side to side within said grooves, said base having an unstable supporting surface whereby said base is rotatable from side-to-side upon said supporting surface.
Claim 19
Dependent Claim
38 words
The apparatus of claim 15 wherein said unstable supporting surface comprises two angularly disposed sides intersecting at a central front to back apex, whereby said base is rotatable about said apex from one side to an other side.
