Putter with replaceable hosel
A putter head comprising a removable and replaceable hosel is disclosed herein. In particular, the putter comprises a first body portion with a plurality of protrusions, a second body portion with a plurality of cavities sized to receive the protrusions, a hosel with an engagement portion that is trapped within one of the cavities by a protrusion, and a mechanical fastener to removably fix each of these pieces together. The fastener preferably extends through a bore on the heel side of the putter head and into a threaded bore within one of the protrusions. In an alternative embodiment, the putter head has a single body portion, which receives the engagement portion of a hosel in a heel side cavity, and which is affixed to the hosel via a fastener that extends through a front surface of the body portion.
1. A putter head comprising:
a first body portion comprising a striking face, a first top surface, a first bottom surface, a first heel side, a first toe side, and first and second protrusions extending from the heel side;
a second body portion comprising a front surface, a second top surface, a second bottom surface, a second heel side, a second toe side, first and second cavities extending into the second heel side, a third cavity extending into the second top surface, and a first through-bore extending from the second toe side into the first cavity;
a hosel comprising a shaft receiving portion and an engagement portion; and
a threaded fastener,
wherein the first cavity is sized to receive at least a portion of the first protrusion,
wherein the second cavity is sized to receive at least a portion of the second protrusion,
wherein the third cavity is in communication with the second cavity,
wherein the first protrusion comprises a threaded bore,
wherein the first through-bore aligns with the threaded bore when the first protrusion is engaged with the first cavity,
wherein the engagement portion is sized to fit within the third cavity,
wherein the engagement portion engages at least a portion of the second protrusion, and
wherein the threaded fastener reversibly fixes the first body portion to the second body portion to affix the hosel within the third cavity.
2. The putter head of claim 1 , wherein the engagement portion is selected from the group consisting of a fourth cavity, a hook, and a second through-bore.
3. The putter head of claim 2 , wherein the engagement portion is a hook.
4. The putter head of claim 1 , wherein the striking face is flush with the front surface when the first body portion is engaged with the second body portion.
5. The putter head of claim 1 , wherein the first body portion comprises a third protrusion extending from the first heel side, and wherein the second body portion comprises a fifth cavity sized to receive at least a portion of the third protrusion.
6. The putter head of claim 5 , wherein the second protrusion is disposed proximate the first top surface, and wherein the third protrusion is disposed proximate the first bottom surface.
7. The putter head of claim 1 , further comprising a seam where the first body portion meets the second body portion, wherein the striking face comprises at least one vertically oriented scoreline, and wherein the at least one vertically oriented scoreline is spaced from the seam.
8. The putter head of claim 1 , wherein the engagement portion comprises a polygonal cross-sectional shape.
9. The putter head of claim 8 , wherein the engagement portion comprises an octagonal cross-section, and wherein a gap is maintained between at least one flat side of the octagonal cross section and a wall of the third cavity when the engagement portion is disposed within the third cavity.
10. The putter head of claim 9 , wherein the gap is no less than 0.0001 inch and no more than 0.0010 inch.
11. The putter head of claim 1 , wherein the engagement portion has a tapering cross-sectionalshape.
12. The putter head of claim 1 , wherein the engagement portion has a cylindrical cross-sectional shape.
13. The putter head of claim 1 , wherein each of the first and second protrusions has a tapering width.
14. The putter head of claim 1 , wherein the striking face comprises a plurality of diamond-shaped scorelines and at least one vertically oriented scoreline.
15. The putter head of claim 1 , wherein the second cavity and the third cavity extend approximately perpendicular to one another.
