Abstract
An improved bowling ball finger grip or insert for a finger in a bowling ball comprising a tubular body adapted to be inserted into the finger hole of the bowling ball. The tubular body has an upper portion and a lower portion, with a bore having a uniform cross section formed through the tubular body that defines at least one finger opening that is located at the upper portion of the finger grip. The lower portion defines a lower wall that is thicker than an upper wall that is defined by the upper portion of the finger grip. The dimensions of the lower portion and lower wall define a base of the finger grip that fits tightly within the finger hole of the bowling ball while giving the upper portion of the finger grip or finger expansion area extra room to expand as the finger of a user swells during play.

A bowling ball finger grip for use by a user and adapted to be inserted into a finger hole of a bowling ball, comprising:
- a soft, elastic, uninterrupted tubular body having a top and a bottom;
- an upper portion defining a finger opening at said top of said tubular body and an upper wall having an at least one upper wall thickness dimension and an upper wall outer diameter;
- a lower portion defining a base and a lower wall having at least one lower wall thickness dimension that is larger than said at least one upper wall thickness dimension and a lower wall outer diameter that is larger than said upper wall outer diameter;
- a bore formed through an interior of said tubular body, said bore commencing at said finger opening;
- a transition section between said upper wall and said lower wall;
- a transition space extending from said top of said tubular body to said transition section such that it surrounds said upper wall, said transition space defined by the difference between said lower wall outer diameter and said upper wall outer diameter;
- wherein said base of said lower portion is configured to fit tightly within said finger hole of said bowling ball and said upper wall is configured to expand into said transition space as a finger of a user swells during play.
A bowling ball finger insert, comprising:
- an elastic, uninterrupted tubular body having an upper portion and a circular lower portion;
- a finger opening at said upper portion of said tubular body;
- a bore commencing at said finger opening;
- a cavity with a uniform oblong cross section, located interior of said tubular body and configured to receive a finger;
- a sloping transition section connecting said upper portion and said lower portion;
- and
- a transition space extending from said top of said tubular body to said transition section such that it surrounds said upper wall;
- wherein said upper portion has an upper wall thickness dimension and an upper wall outer diameter and said lower portion has a lower wall thickness dimension and a lower wall outer diameter, said lower wall outer diameter being larger than said upper wall outer diameter;
- and
- wherein said transition space is defined by the difference of said lower wall outer diameter and said upper wall outer diameter and said upper wall expands into said transition space as a finger of a user swells.
