DETAILED DESCRIPTION OF THE INVENTION

The present invention is directed to a golf club head, and particularly a putter, having a face insert designed to give a golfer control over the spin imparted to a golf ball when the insert impacts said ball.

In a first, preferred embodiment, shown in FIGS. 1-4, the putter head 10 has a face 20, a rear surface 30 opposite to, and approximately parallel with, the face 20, a recessed area 40 with a face region 42 and a sole region 44, a sound chamber 50 with a primary chamber 52 and a secondary chamber 54, a sole portion 60, a top portion 70, a heel 80, a toe 85, a hosel 90, and an L-shaped face insert 100, also called a partial face cup, having a face portion 110, a sole portion 120, and a hinge portion 130 where the face and sole portions 110, 120 meet. The sound chamber 50 may have any of the features or dimensions disclosed in U.S. patent application Ser. No. 14/662,400, the disclosure of which is hereby incorporated by reference in its entirety herein. The face insert 100 preferably is composed of a metal material, but in other embodiments may be a polymeric material such as plastic or urethane.

The hinge portion 130 includes a groove 135, which preferably extends the entire horizontal length of the hinge portion 130 but in other embodiments may only extend along part of the length of the hinge portion 130. The groove 135 preferably is disposed on the inner surface of the hinge portion 130, such that it is hidden from view when the face insert 100 is affixed to the head 10, but in other embodiments the groove 135 may be on an external surface of the hinge portion 130 and thus be visible to a golfer. The groove 135 allows the face portion 110 of the face insert 100 to flex inwards towards the sound chamber 50 when it impacts a ball, and imparts a different amount of topspin to the ball depending on where the ball strikes the face portion 110. The face insert 100 is affixed to the putter head 10 only at the sole region 44 of the recessed area 40; the face portion 110 of the face insert 100 preferably is not attached to any portion of the putter head 10 so that it can flex into and out of the face region 42 of the recessed area 40 independently of the putter head 10. The sole portion 120 of the face insert 100 preferably is welded within the sole region 44 of the recessed area 40, but in other embodiments may be permanently or removably attached with an adhesive material.

In an alternative embodiment, the putter head 10 may have all of the same elements as the first embodiment, except that the recessed area 40 comprises a face region 42 and a crown region 46, and the face insert 100 is r-shaped, such that it has a face portion 110, a crown portion 140, and a hinge portion 130 with a groove 135 extending along an inner surface of the hinge portion 130. In this embodiment, the crown portion 140 is affixed within the crown region 46 of the recessed area and the face portion 110 is unattached to any portion of the putter head 10.

A second embodiment is shown in FIGS. 5-10. In this embodiment, the putter head 200 has a body 210 with a face 211, a rear surface 212, a recessed area 213 with a face portion 213a and a sole portion 213b, a sole portion 214, a top portion 215, a heel 216, a toe 217, a hosel 218, and a sound chamber 219, and a face insert 220 sized to fit within the recessed area 213. The face insert 220 is a partial face cup, with a face portion 222, a sole portion 224, a sole hinge 225 between the face and sole portions 222, 224, a crown portion 226, a crown hinge 227 between the face and crown portions 222, 226, and a groove 228 disposed on the interior surface of the crown hinge 227. The groove 228 preferably extends along the entire length of the crown hinge 227 as shown in FIG. 8, but in other embodiments may only extend along part of the length of the crown hinge 227. The groove 228 preferably is disposed on the inner surface of the crown hinge 227, such that it is hidden from view when the face insert 220 is affixed to the head 220, but in other embodiments the groove 228 may be on an external surface of the crown hinge 227 and thus be visible to a golfer.

The groove 228 allows the face and sole portions 222, 224 of the face insert 220 to flex inwards towards the sound chamber 219 when the face portion 222 impacts a ball, and imparts a different amount of topspin to the ball depending on where the ball strikes the face portion 222. As shown in FIG. 7, the crown portion 226 of the face insert 220 is affixed to the body 210 in the face portion 213a of the recessed area 213 only proximate the top portion 215 of the body 210. The face portion 222 of the face insert 220 preferably is not attached to any portion of the body 210 so that it can flex into and out of the face portion 213a of the recessed area 213 independently of the body 210. The sole portion 224 of the face insert 220 also is not affixed to any portion of the body 210, as shown in FIG. 7, so that the face insert 220 can flex inwards when it makes contact with a golf ball.

The putter head 200 of the third embodiment, shown in FIGS. 11-13, is identical to that of the second embodiment, except that the groove 258 in the face insert 250 is disposed along a horizontal midline 257 on the rear surface 256 of the face portion 252. This groove 258 allows the lower region of the face portion 252 and the sole portion 254 of the face insert 250 to flex inwards towards the sound chamber 219 when the face portion 252 impacts a ball.

In a fourth embodiment, shown in FIGS. 14 and 15, the putter head 300 has all of the same elements as the preferred embodiment, except that the recessed area 310 is only located in the face 305, and the face insert 320 does not have any rearward extending portions. In this embodiment, a pair of pins 330, 335 extend from the two upper corners 311, 312 of the recessed area 310 and elevate the face insert 320 a distance D away from the face 305. The pins 330, 335 act as pivot points for the face insert 320, which flexes inwards and imparts different amount of topspin to a golf ball depending on where the ball strikes the face insert 320. Though the face insert 320 may be composed of a polymeric material, in this embodiment it preferably is composed of a metal material and is welded to the pins 330, 335, which are themselves metal and are welded to the putter head 300 inside or proximate the recessed area 310.

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.
