Abstract

A riser in combination with a semispherical ball having a rigid base plate of a given diameter, the riser elevates the ball. The riser includes a portion extending in a longitudinal direction of the riser. The portion has an outside diameter and an inside diameter dimensioned for receiving the given diameter of the rigid base plate. A further portion is adjacent the portion and extends in the longitudinal direction of the riser. The further portion has a further inside diameter. The further inside diameter is smaller than the inside diameter thereby defining a shoulder therebetween. The shoulder is configured for supporting the base plate.

Claims

1. The exercise ball riser for elevation in combination with a semispherical ball having a rigid base plate of a predetermined diameter, the riser for elevating the ball comprising:

a first portion extending in a longitudinal direction of the riser, said first portion having an outside diameter and an inside diameter dimensioned for receiving the predetermined diameter of the rigid base plate;

a second portion adjacent said first portion and extending in the longitudinal direction of the riser, said second portion having an inside diameter, said inside diameter of said second portion being smaller than said inside diameter of said first portion thereby defining a shoulder therebetween, said shoulder being configured for supporting the base plate;

a third portion adjacent said second portion and extending in the longitudinal direction of the riser, said third portion having outside diameter being larger than said outside diameter of said first portion for defining a collar about a circumference of the riser, said third portion having a base surface, and said third portion having an inside diameter being greater than said inside diameter of said second portion for defining an undercut of said shoulder.

2. The riser according to claim 1, further comprising a plurality of longitudinally extending ribs formed on said inside diameter of said third portion and abutting said undercut.

3. The riser according to claim 2, wherein said first portion has a plurality of longitudinally extending grooves formed therein at said outside diameter of said first portion, each of said grooves for accommodating a respective one of said ribs therein.

4. The riser according to claim 3, wherein said ribs are tapered in the longitudinal direction from said undercut to said inside diameter of said third portion.

5. The riser according to claim 3, wherein said base surface is spaced from said undercut so that said base surface rests on said collar when one of the risers is stacked on another one of the risers.

6. The riser according to claim 3, wherein said base surface has a textured surface finish.

7. The riser according to claim 4, wherein said first portion has radially distributed cutouts formed therein configured to correspond to projections of the rigid base plate.
