Abstract
An interchangeable finger insert apparatus for a bowling ball includes a cylindrical outer body configured to be disposed in a bowling ball hole. The outer body defines an internal bore open to a first end of the outer body and a number of protrusions extending from an inner surface of the bore. The finger insert apparatus also includes a cylindrical inner slug sized to be inserted into the bore of the outer body. The inner slug defines a plurality of helical grooves corresponding to the protrusions of the outer body. At least one of the protrusions is uniquely sized relative to other protrusions and corresponds to only one of the helical grooves such that the slug may be rotatably inserted to a single set position.
Claims18
An interchangeable finger insert apparatus for a bowling ball comprising:
- a cylindrical outer body configured to be disposed in a bowling ball hole, the outer body defining an internal bore open to a first end of the outer body, a base at a second end of the outer body and a plurality of protrusions extending from an inner surface of the bore;
- a cylindrical inner slug sized to be inserted into the bore of the outer body, the inner slug defining a plurality of helical grooves that correspond to the plurality of protrusions of the outer body,
- wherein one of the protrusions is uniquely sized relative to other protrusions and corresponds to only one of the helical grooves such that the slug may be rotatably inserted to a single set position;
- and
- a compression element attachable to the base wherein the inner slug compresses the compression element when inserted into the bore resulting in a resistive force retaining the inner slug in the set position.
An interchangeable finger insert apparatus for a bowling ball comprising:
- a cylindrical outer body defining an internal bore being open to a first end of the outer body and at least one protrusion extending from an inner surface of the bore;
- an inner slug insertable into the bore of the outer body and defining a plurality of helical grooves on an outer surface, the inner slug further defining a retaining socket disposed at a terminal end of at least one helical groove;
- and
- a compression element extending from one of the outer body and the inner slug to engage an other of the outer body and the inner slug;
- wherein at least one of the helical grooves corresponds to the at least one protrusion of the outer body such that the at least one protrusion traverses at least one corresponding helical groove to nest within the retaining socket to define a set position of the inner slug, and the compression element generates a resistive force when the inner slug is in the set position thereby retaining at least one protrusion within the retaining socket.
A bowling system including an interchangeable finger insert comprising:
- a bowling ball defining a blind hole;
- a cylindrical outer body disposed in the blind hole and defining an internal bore being open to a first end of the outer body and at least one protrusion extending from an inner surface of the bore near a second end of the outer body;
- a compression element affixed to the second end of the outer body;
- and
- an inner slug sized to fit within the bore of the outer body and defining a plurality of helical grooves on an outer surface that correspond to the at least one protrusion of the outer body,
- wherein the inner slug is capable of rotatable insertion into the bore of the outer body such that the at least one protrusion traverses at least one helical groove and the compression element generates a resistive force to retain the inner slug in a set position.
