Abstract
Abstract An angularly adjustable ski deck is selectively downwardly or upwardly inclinable. A stand is pivotally connected to a frame, which frame rotatably supports a pair of belt rollers at either end thereof along a line transverse to the length of said frame. An endless belt is mounted around the two rollers, and is adapted to be moved in a single direction against the movement of a skier. A pair of slide tracks are formed within the belt to simulate a cross-country skiing path. Ski-on and ski-off ramps are provided at either end of the ski deck.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
126 words
An apparatus for simulating skiing and terrain encountered during skiing, comprising: support means resting on a support surface; an elongated frame having belt rollers rotatably mounted transverse thereto, said elongated frame pivotally connected to said support means to provide selective angular positioning of said frame between downwardly inclined and upwardly inclined positions corresponding to said terrain; motive means pivotally connected to said frame adapted to pivotally move said frame relative to said support means; an endless belt mounted around said belt rollers, said belt having two parallel slide tracks formed therein for simulating a ski track; and means for rotating said belt about said belt rollers and for varying the velocity of said belt rollers and said belt dependent on the angular position of said frame.
Claim 2
Independent Claim
126 words
An apparatus for simulating skiing and terrain encountered during skiing, comprising: support means resting on a support surface; an elongated frame having belt rollers rotatably mounted transverse thereto, said elongated frame pivotally connected to said support means to provide selective angular positioning of said frame between downwardly inclined and upwardly inclined positions corresponding to said terrain; motive means pivotally connected to said frame adapted to pivotally move said frame relative to said support means; an endless belt mounted around said belt rollers, said belt having two parallel slide tracks formed therein for simulating a ski track; and means for rotating said belt about said belt rollers and for varying the velocity of said belt rollers and said belt dependent on the angular position of said frame.
Claim 3
Independent Claim
122 words
An apparatus for simulating skiing comprising: support means resting on a support surface; an elongated frame having belt rollers rotatably mounted transverse thereto, said elongated frame pivotally connected to said support means to provide selective angular positioning of said frame between downwardly inclined and upwardly inclined positions; motive means pivotally connected to said frame adapted to pivotally move said frame relative to said support means; an endless belt mounted around said belt rollers, said belt having two parallel slide tracks formed therein for simulating a ski track; a ramp hingeably connected to said frame at either end of said frame defining an essentially continuous ski surface with said endless belt; and means for rotating said belt rollers and said belt mounted thereto.
Claim 4
Independent Claim
122 words
An apparatus for simulating skiing comprising: support means resting on a support surface; an elongated frame having belt rollers rotatably mounted transverse thereto, said elongated frame pivotally connected to said support means to provide selective angular positioning of said frame between downwardly inclined and upwardly inclined positions; motive means pivotally connected to said frame adapted to pivotally move said frame relative to said support means; an endless belt mounted around said belt rollers, said belt having two parallel slide tracks formed therein for simulating a ski track; a ramp hingeably connected to said frame at either end of said frame defining an essentially continuous ski surface with said endless belt; and means for rotating said belt rollers and said belt mounted thereto.
Claim 5
Dependent Claim
24 words
The invention defined in claim 2, further including means for allowing the unconnected end of said ramp to freely move on said support surface.
Claim 6
Dependent Claim
29 words
The invention defined in claim 2, wherein said segments are formed of a backing material, said backing material joined to a material having flexible fibers extending from the surface.
Claim 7
Dependent Claim
67 words
The invention defined in claim 2, wherein said frame has at least one pair of hangers rigidly connected to and depending from each side of said frame to a position below said endless belt, each said pair of hangers rotatably mounting at least one idler roller along a line transverse to the length of said frame, said idler roller maintaining a preselected position below said endless belt.
Claim 8
Dependent Claim
16 words
The invention defined in claim 2, further including side platforms extending laterally away from said frame.
Claim 9
Independent Claim
169 words
An apparatus for simulating skiing, comprising: support means resting on a support surface; an elongated frame having belt rollers rotatably mounted transverse thereto, said elongated frame pivotally connected to said support means to provide selective angular positioning of said frame between downwardly inclined and upwardly inclined positions; motive means pivotally connected to said frame adapted to pivotally move said frame relative to said support means; an endless belt mounted around said belt rollers, said belt having three longitudinal segments, each longitudinal segment connected to at least one adjacent segment by a relatively narrow track, said connection between said track and said longitudinal segments including an upper surface covering and a lower surface covering having an elongated flexible cord of substantially the same length as said endless belt therebetween, said elongated flexible cord of generally circular transverse cross section to the length of said cord, said upper and lower coverings being connected along each side edge thereof to one of said longitudinal segments; and means for rotating said belt rollers.
Claim 10
Independent Claim
169 words
An apparatus for simulating skiing, comprising: support means resting on a support surface; an elongated frame having belt rollers rotatably mounted transverse thereto, said elongated frame pivotally connected to said support means to provide selective angular positioning of said frame between downwardly inclined and upwardly inclined positions; motive means pivotally connected to said frame adapted to pivotally move said frame relative to said support means; an endless belt mounted around said belt rollers, said belt having three longitudinal segments, each longitudinal segment connected to at least one adjacent segment by a relatively narrow track, said connection between said track and said longitudinal segments including an upper surface covering and a lower surface covering having an elongated flexible cord of substantially the same length as said endless belt therebetween, said elongated flexible cord of generally circular transverse cross section to the length of said cord, said upper and lower coverings being connected along each side edge thereof to one of said longitudinal segments; and means for rotating said belt rollers.
Claim 11
Dependent Claim
35 words
The invention defined in claim 7 wherein said frame has an upper flat rigid underlying surface connected thereto and extending substantially over the length of said frame, said underlying surface positioned beneath said endless belt.
Claim 12
Dependent Claim
15 words
The invention defined in claim 8 wherein said underlying surface is a rigid metal tray.
