Abstract
The invention includes a concave cup specifically designed to hold various size basketballs. The cup has a stem which inserts and is held securely in a precision bearing, which in turn is held firmly in the splined finger gripping portion of the invention. The splined finger gripping portion of the device is held securely on the finger of a person, by an o-ring. The o-ring rolls up and down on the splined portion and is prevented from rolling off by the molded protrusions at the bottom of the splined finger gripping portion of the invention. The splines are tapered to allow for expansion and contraction to fit various finger sizes.
