## Abstract

An exercise apparatus especially suitable for simulating skiing conditions. The apparatus comprises a base which supports a rotatable component which, in turn, supports a platform for supporting a user. The rotational component includes a unidirectional element limiting the direction of rotation of the component. A biasing assembly assists and resists the movement and varies the speed of the rotational component in response to a displacement of the same.

## Claims

### Claim 1

An exercise apparatus comprising:
a base;
a crank assembly rotatably supported by said base, said crank assembly including a plurality of unidirectional bearings joining said crank assembly to said base, said unidirectional bearings limiting a rotation of said crank assembly to a single direction;
a platform, rotatably engaged with said crank assembly, for supporting a user;
a biasing assembly, operatively coupled to said crank assembly and said base, for applying a rotational force to said crank assembly, said rotational force being variable in accordance with a position of said crank assembly;
said biasing assembly including:
a spring for producing the rotational force being applied to said crank assembly;
a sprocket for applying the rotational force to said crank assembly, said sprocket rotatably engaging said crank assembly; and
a chain for delivering the rotational force from said spring to said sprocket, said chain having a first segment engaging said sprocket and a second segment connected to said base by said spring; and
a handle for a user to grasp, said handle being secured to said base.

### Claim 2 (depends on 1)

The exercise apparatus according to claim 1, wherein said platform includes:
a rigid core having an outer surface and being rotatably engaged with said crank assembly; and
a padding material joined to said outer surface.

### Claim 3

An exercise apparatus comprising:
a base;
a crank assembly rotatably supported by said base, said crank assembly including a plurality of unidirectional bearings joining said crank assembly to said base, said unidirectional bearings limiting a rotation of said crank assembly to a single direction, said rotation of said crank assembly including a first and second half cycle, said first halve cycle being defined by a downward stroke and said second half cycle being defined by an upward stroke;
a platform, rotatably engaged with said crank assembly, for supporting a user;
means for receiving and retaining a user's foot positioned atop said platform, said retaining means being adjustable to the user's foot;
a biasing assembly, operatively coupled to said crank assembly and said base, said biasing assembly including means for applying a rotational force to said crank assembly, said force applying means including means for accumulating energy upon said downward stroke of said crank assembly and means for delivering energy upon said upward stroke of said crank assembly; and
a handle for a user to grasp, said handle being secured to said base.

### Claim 4 (depends on 1)

The exercise apparatus according to claim 1, wherein said base includes:
left and right longitudinal rods positioned in a substantially parallel and spaced apart relationship; and
front and rear laterally extending rods positioned in a substantially parallel and spaced apart relationship, said front and rear laterally extending rods further connecting said left and right longitudinal rods so as to form a substantially rectangular and planar frame structure.

### Claim 5 (depends on 1)

The exercise apparatus according to claim 1, wherein said crank assembly includes:
a first crank rotatably joined to said base by a first of said plurality of unidirectional bearings;
a second crank rotatably joined to said base by a second of said plurality of unidirectional bearings, said first crank being laterally spaced from, and axially aligned with, said second crank; and
a laterally disposed connecting rod joining said first crank to said second crank for rotatably supporting said platform.

### Claim 6 (depends on 1)

The exercise apparatus according to claim 1, wherein said base includes means for anchoring said force applying means to said base, said anchoring means being attached to said base and being engagable with said force applying means.

### Claim 7 (depends on 1)

The exercise apparatus according to claim 1, wherein said force applying means includes means for adjusting the rotational force applied to said crank assembly, said force adjusting means being attached to said force applying means and being engagable with said base.

### Claim 8 (depends on 1)

The exercise apparatus according to claim 1, wherein said handle includes a standard rigidly secured to said base.

### Claim 9 (depends on 1)

The exercise apparatus according to claim 1, further including:
a seat assembly for supporting a user's upper body,
means for removably attaching to said seat assembly to said base, said seat assembly being pivotally adjustable.

### Claim 10 (depends on 1)

The exercise apparatus according to claim 1, wherein said rotation of said crank assembly includes a first and second half cycle, said first halve cycle being defined by a downward stroke and said second half cycle being defined by an upward stroke, and
wherein said force applying means includes means for accumulating energy upon said downward stroke of said crank assembly and means for delivering energy upon said upward stroke of said crank assembly.
