Abstract

An exerciser for skiers in the form of a hollow bowl having a platform on which the skier strands; the outer surface of the bowl having a spherically shaped base portion and angularly related essentially conical portions which permit the skier to select angles at which the platform is tilted to predetermine the intensity of the exercise; the bowl containing a fixed weight at its base portion to lower its center of gravity and a vertically adjustable weight to change the center of gravity.

Claims

1. An exerciser for skiers, comprising:

a. a base member having an apex of spherical contour and a series of concentric angularly related conical surfaces of increasing slope;

b. and a substantially flat platform covering the entire base member to define the uppermost surface thereof and dimensioned to receive substantially only the feet of the user whereby the user, when standing on said platform, may rock the base member to a selected conical surface to control the intensity of his exercise, said apex of spherical contour being of a diameter that is a minor portion of the diameter of said platform and centrally located therebelow whereby to be between the feet of a user standing on said platform.

2. An exerciser, as defined in claim 1, wherein:

a. said base member includes a fixed weight at its apex portion.

3. An exerciser, as defined in claim 1, wherein:

a. said base member is hollow and includes a centrally located weight and means for adjusting the position of the weight to move the center of gravity.

4. An exerciser, as defined in claim 1 for skiers, comprising:

a. a hollow base member having an apex of spherical contour and a series of concentric, angularly related surfaces defining conical areas of increasing slope for presentation to an underlying floor, said base member terminating in a rim;

b. a platform covering the base member and secured to said rim, the platform having an aperture for access to said base member;

c. and vertically adjustable weight means in said base member accessible for adjustment from the central portion of said platform.

5. An exerciser for skiers, as defined in claim 4, wherein said weight means includes:

a. a fixed weight secured in the apex region of the base member;

b. a screwthreaded post projecting upwardly therefrom;

c. and an adjustable weight carried by said post.
