 DETAILED DESCRIPTION OF THE INVENTION

The present invention is directed to a golf club head, and particularly a putter head, with a replaceable face insert.

In a first embodiment, shown in FIGS. 1-7, the putter head 10 has a body 20 with a heel side 21 proximate a hosel 22, a toe side 23, a front surface 24, a top portion 30 extending rearward from an upper edge 25 of the front surface 24, a sole portion 40 extending rearward from a lower edge 26 of the front surface 24, and a rear end 27. A face cavity 50 extends into the front surface 24 and communicates with a heel-side cavity 52 and a toe-side cavity 54, each of which is disposed behind the face cavity 50 along a front-to-back x-axis extending perpendicular to the front surface 24. As shown in the Figures, each of the heel-and toe-side cavities 52, 54 has a rear opening facing the rear end 27 of the body 20, but in an alternative embodiment, a rear wall (not shown) may enclose the back side of each of these cavities 52, 54.

The top portion 30 has a recessed central area 35 sized to receive the front portion of a cover piece 200. A heel-side top opening 32 extends through the top portion 30 and communicates with the heel-side cavity 52, and a toe-side top opening 34 extends through the top portion and communicates with the toe-side cavity 54. The sole portion 40 has a heel-side depression 42 extending into an interior sole surface 45 and aligned with the heel-side top opening 32 along a vertical z-axis extending perpendicular to the x-axis, and a toe-side depression 44 extending into the interior sole surface 45 and aligned with the toe-side top opening 34 along the vertical z-axis.

The body 20 engages a face insert 100 having a striking portion 110 with a striking surface 112, a rear surface 114 opposite the striking surface, and a periphery edge 116 extending approximately perpendicular to, and connecting, the striking and rear surfaces 112, 114. A sealing gasket 120 is affixed to the periphery edge 116 to ensure that there are no frontal gaps in the putter head 10 when the face insert 100 is affixed to the body 20. The sealing gasket 120 preferably does not make contact with any portion of the striking surface 112.

Cylindrical heel-and toe-side support structures 130, 140 extend from the rear surface 114 of the striking portion 110, each having an elongated through-bore 135, 145 extending along the z-axis from upper edges 132, 142 to lower edges 134, 144 of the support structure 130, 140. The upper edges 132, 142 and lower edges 134, 144 are preferably flush with the periphery edge 116 of the striking portion 110, so that the cylindrical support structures 130, 140 extend along the entire vertical height H of the striking portion 110, but in alternative embodiments, the cylindrical support structures 130, 140 may not extend along the entire vertical height H. Each elongated through-bore 135, 145 includes a linear bearing 150, 155, which is trapped within the elongated-through bore 135, 145 between snap rings 160, 162, 164, 166 that at least partially disposed within circular grooves 131, 133, 141, 143 that are in communication with the elongated through-bores 135, 145.

The heel-side support structure 130 is sized to fit within the heel-side cavity 52, and the toe-side support structure 140 is sized to fit within the toe-side cavity. When these support structures 130, 140 are fully disposed within their respective cavities 52, 54, the striking portion 110 is seated within the face cavity 50 so that the striking surface 112 is approximately flush with the front surface 24 of the body and the sealing gasket 120 creates a seal between the face insert 100 and the body 20. Fully engaging the face insert 100 with the body 20 also causes the elongated through-bore 135 in the heel-side support structure 130 to align with the heel-side top opening 32 and the heel-side depression 42, and the elongated through-bore 145 in the toe-side support structure 140 to align with the toe-side top opening 34 and the toe-side depression 44.

Once the face insert 100 is disposed within the cavities 50, 52, 54 of the body 20 as described above, retaining rods 170, 180 are used to secure the face insert 100 to the body 20. The first retaining rod 170 is inserted into the heel-side elongated through-bore 135 through the heel-side top opening 32 so that it extends through the bore 152 in the linear bearing 150 and a lower end 172 abuts the heel-side depression 42. The second retaining rod 180 is inserted into the toe-side elongated through-bore 145 through the toe-side top opening 34 so that it extends through the bore 157 in the linear bearing 155 and a lower end 182 abuts the toe-side depression 44. The linear bearings 150, 155 help to snugly retain the retaining rods 170, 180 within their respective elongated through-bores 135, 145. Each retaining rod 170, 180 has tapered upper and lower ends 174, 184, 182, which helps to center the retaining rods 170, 180, within their respective, elongated through-bores 135, 145, and to engage the depressions 42, 44 in the sole portion 40.

When the retaining rods 170, 180 are fully engaged with the face insert 100 and the body 20, the cover piece 200 is attached to the body 20 to reversibly fix the retaining rods 170, 180 in place. The cover piece 200 comprises an external surface 205 with alignment markings 210 and an internal surface 220 with a pair of bosses 222, 224, one extending from a frontal heel side of the cover piece 200, and the other extending from a frontal toe side of the cover piece 200. The heel side boss 222 receives the tapered upper end 174 of the first retaining rod 170, and the toe side boss 224 receives the tapered upper end 184 of the second retaining rod 180. The cover piece 200 preferably is then reversibly affixed to the body 20 with snap features, temporary adhesive material, and/or mechanical fasteners such as bolts or screws (as shown in FIGS. 8-12); doing so places pressure on the retaining rods 170, 180 and holds them, and the face insert 100, in place within the body 20. The front portion 215 of the cover piece 200, which is received by the recessed central area 35 of the top portion 30, preferably is thinner than the rear portion 217 of the body so that the putter head 10 has a flush upper surface 15.

A second, preferred embodiment of the present invention is shown in FIGS. 8-12. This putter head 10 has most of the same features as the embodiment shown in FIGS. 1-7, but instead of retaining rods 170, 180, the putter head 10 of the preferred embodiment includes a pair of elongated bolts 70, 80, also referred to as mechanical fasteners, which are inserted into the body 20 via the sole portion 40 instead of the top portion 30. Each bolt 70, 80 has a head portion 72, 82, an elongated extension portion 74, 84, and a threaded tip portion 76, 86, while the sole portion 40 comprises a heel-side sole opening 46 surrounded by a heel-side flange portion 47 and a toe-side sole opening 48 surrounded by a toe-side flange portion 49.

The cover piece 200 in this embodiment includes heel- and toe-side threaded internal bores 230, 235, each of which is supported by a raised boss 240, 245 extending from the external surface 205 of the cover piece 200. When the cover piece 200 is properly disposed on the body 20, the heel-side threaded internal bore 230 vertically aligns with the heel-side opening 46, and the toe-side threaded internal bore 235 vertically aligns with the toe-side opening 48. The cover piece 200 in this embodiment also includes first and second through-bores 250, 255 at a middle section 214, through which smaller bolts 90, 92 are inserted to engage threaded bores 94, 96 located in a middle region 43 of the sole portion 40. In this way, the cover piece 200 can be reversibly affixed to the body 20.

As shown in FIGS. 11 and 12, when each of the cover piece 200 and the face insert 100 is fully engaged with the body 20, the bolt 70 is attached to the body 20 by threading the elongated extension portion 74 through the heel-side sole opening 46, through the elongated through bore 135, and through the bore 152 in the linear bearing 150, until the threaded tip portion 76 engages the heel-side threaded internal bore 230 and the head portion 72 abuts an external surface of the heel-side flange portion 47. The other bolt 80 is attached to the body in the same way, threading the elongated extension portion 84 through the toe-side sole opening 48, through the elongated through-bore 145, and through the bore 157 in the linear bearing 155, until the threaded tip portion 86 engages the toe-side threaded internal bore 235 and the head portion 82 abuts an external surface of the toe-side flange portion 49. Tightening the bolts 70, 80 puts them in tension between the cover piece 200 and the sole portion 40.

In an alternative embodiment, instead of a removable cover piece 200, the heel- and toe-side threaded internal bores 230, 235 may be integrally formed with the top portion 30 of the body 20, such that the body does not require a separate cover piece 200 to cap off any openings in the top portion 30.

The present invention is useful to a golfer because they can select a preferred putter body 20 and a preferred face insert 100 separately from one another. As shown in FIGS. 1-7, the face insert 100 of that embodiment includes striking face technology described in U.S. Pat. Nos. 9,577,484, 9,265,996, 8,915,798, 8,696,492, or 8,684,860, the disclosure of each of which is incorporated by reference in its entirety herein. In the embodiment shown in FIGS. 8-12, the face insert 100 includes White Hot striking face technology, such as that disclosed in U.S. Pat. Nos. 6,238,302, 6,273,831, or 6,273,832, the disclosure of each of which is incorporated by reference in its entirety herein. Some alternative striking surface 112 options are shown in FIGS. 13-16. In the embodiment shown in FIGS. 13 and 14, the striking surface 112 comprises a recessed area 300 with a plurality of bulbous bristles 302 extending perpendicular from the recessed base 304, such that the top edges 303 of the bristles are flush with the rest of the striking surface 112. In the embodiment shown in FIGS. 15 and 16, the striking surface 112 comprises a recessed area 300 filled with an insert 310 made up of rows of hollow, rectangular tubes 312 elongated along the heel-to-toe y axis, each of which can move upon impact with a golf ball independently of other tubes 312. In still other embodiments, the face insert 100 may comprise the technology disclosed in U.S. Pat. No. 9,776,051, the disclosure of which is hereby incorporated by reference in its entirety herein.

Each piece of the putter head 10 preferably is composed of a high strength material, such as titanium alloy or stainless steel, though the linear bearings 150, 155 preferably are composed of an anodized aluminum alloy with a Frelon® liner coating. Alternatively, portions of the putter head 10, such as the hosel 22 or the cover piece 200, can be formed of a lighter weight material such as aluminum ally, carbon composite, or plastic to reduce the overall weight of the putter head 10 and ensure a low center of gravity. The material composition of the different parts of the putter head 10 can, however, be adjusted as desired by the golfer to change the center of gravity location.

From the foregoing it is believed that those skilled in the pertinent art will recognize the meritorious advancement of this invention and will readily understand that while the present invention has been described in association with a preferred embodiment thereof, and other embodiments illustrated in the accompanying drawings, numerous changes, modifications and substitutions of equivalents may be made therein without departing from the spirit and scope of this invention which is intended to be unlimited by the foregoing except as may appear in the following appended claims.
