Abstract:
The combination of a bowling ball and a customized, anatomically correct insert for the bowling ball hole, the insert comprising:a main body portion having a first end and a second end,an outer portion having a first end and a second end, the first end being flush with the surface of a bowling ball with which the insert is intended to be used, and the second end being connected to the first end of the main body portion of the insert, the bowling ball having a finger hole, the outer portion of the insert being positioned in the bowling ball finger hole adjacent the surface of the bowling ball when the insert is positioned for use in the bowling ball finger hole, and the outer portion of the insert having a greatest external dimension substantially equal to an internal dimension of the bowling ball finger hole, so as to be capable of being press-fit into the bowling ball finger hole, yet not being so large as to be subject to becoming so tightly stuck that it cannot be selectively removed by the bowler from the bowling ball finger hole;the main body portion of the insert having an outer side wall with a greatest external dimension less than a greatest external dimension of the outer portion of the insert so that an air space remains between the outer side wall of the central portion and a portion of the bowling ball defining the bowling ball finger hole; andthe main body portion of the insert and the outer portion of the insert having formed therein an anatomically correct cavity for receiving a finger of a bowler for whom the insert is custom-made;further comprising a plate connected coaxially to the second end of the main body portion and positioned substantially at a bottom of the bowling ball finger hole when the insert is disposed for use in the bowling ball finger hole;wherein the plate has an aperture formed therein, the aperture in the plate being internally threaded to thereby permit engagement of the aperture with corresponding threads on the external surface of a tool, to facilitate insertion into and removal of the insert from the bowling ball finger hole by use of the tool.
