Abstract
A golf club has a clubhead with a neck portion or hosel integrally formed therewith. The hosel has a generally cylindrical shape with a corresponding cylindrical concentric bore hole formed in a portion of the hosel. One or more depressions of a predetermined shape are formed in the outer surface of the hosel wall material by selectively removing portions of the hosel wall material. The depressions are formed to a depth that does not penetrate the entire thickness of the hosel wall material. This leaves the entire inner surface of the hosel wall material available for adhesion to a golf club shaft inserted into the hosel bore hole. The depressions may take various shapes, and may be disposed at predetermined locations around the circumference of the outer surface of the hosel wall material.
Claims18
A head portion of a golf club, comprising:
- a. a striking face;
- b. a heel;
- c. a toe;
- d. a sole;
- and
- e. a hosel having a bore formed at least a portion of the way through a material that constitutes the hosel wherein a hosel wall continuously surrounds the bore, the hosel wall having a portion of the wall material removed in the form of at least one depression beginning at an outer surface of the hosel wall and extending inward toward a center axis of the hosel, each depression being formed in the hosel wall at a depth of thickness of the hosel wall that is less than the entire thickness of the hosel wall, the depth of each depression being a maximum distance that the depression achieves as measured from the hosel wall outer surface, the depth of each depression being in the range of from ten percent of the hosel wall thickness to 75 percent of the hosel wall thickness, wherein a ten percent depth of each depression ranges from 0.0013 inches for a minimum hosel wall thickness of 0.0125 inches to 0.0525 inches for a maximum hosel wall thickness of 0.525 inches, wherein a 75 percent depth of each depression ranges from 0.0094 inches for a minimum hosel wall thickness of 0.0125 inches to 0.3938 inches for a maximum hosel wall thickness of 0.525 inches.
A head portion of a golf club, comprising:
- a. a striking face;
- b. a heel;
- c. a toe;
- d. a sole;
- and
- e. a hosel having at least one depression formed in the hosel beginning at an outer surface of the hosel wall and extending inward toward a center axis of the hosel, a depth of each depression being a maximum distance that the depression achieves inward toward the center axis of the hosel as measured from an outer surface of the hosel, the depth of each depression being in the range of from ten percent to 75 percent of the thickness of the hosel, wherein a length of the hosel is in the range of from 0.1 inches to 2.5 inches, an outside diameter of the hosel is in the range of from 0.250 inches to 1.250 inches;
- with a hosel length of 0.1 inches a hosel wall outer surface area ranges from 0.0785 square inches to 0.3927 square inches for a corresponding hosel outside diameter of from 0.250 inches to 1.250 inches, respectively;
- with a hosel length of 2.5 inches, the hosel wall outer surface area ranges from 1.9635 square inches to 9.8175 square inches for a corresponding hosel outside diameter of from 0.250 inches to 1.250 inches, respectively.
