ABSTRACT:
The present invention is a thumb insert in combination with a bowling ball having a thumb-hole which has an internal cylindrical sidewall. The thumb insert includes a substantially cylindrical member which is formed from a non-metallic, flexible material and which has a base portion. The substantially cylindrical member has an external cylindrical sidewall which is fixedly coupled to the internal cylindrical sidewall of the thumb-hole of the bowling ball adjacent to the base portion thereof. The substantially cylindrical member has a first longitudinal peripheral edge, a second longitudinal peripheral edge which is disposed oppositely and parallel to the first longitudinal peripheral edge and a third transverse peripheral edge which is adjacent and contiguous to both the first and second longitudinal peripheral edges. The first and second longitudinal peripheral edges extend substantially, but not completely, to the base portion thereof. The thumb insert also includes a flexible member which has an external semi-cylindrical surface and an internal semi-cylindrical sidewall. The thumb insert is disposed in the space formed by the first and second longitudinal peripheral edges and the third transverse peripheral edge so that the bowler can place the back of his thumb against the internal semi-cylindrical sidewall of the first portion and the front of his thumb contacts the internal semi-cylindrical sidewall of the second portion. The second portion is fixedly and rigidly coupled to the base portion so that the bowler can resiliently and snugly insert his thumb into the thumb-hole of the bowling ball.
