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.
Claims10
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.

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.
