- the reflective surface 814 reflects an image 817 of a portion of the golf ball 816 .
- the portion 815 outside the guide lines 830 is not reflective as represented by the speckles.
- the golf putter head 110 further includes a heel portion 132 , a toe portion 134 , and a rear surface 136 positioned opposite (i.e., on a backside of) the striking surface 112 and the reflective surface 114 .
- the golf putter head 110 also includes a weighted perimeter portion 138 adjacent the heel portion 132 and a weighted perimeter portion 140 adjacent the toe portion 134 .
- the weighted perimeter portions 138 and 140 are defined by enhanced sidewall buttresses which function to distribute weight wider than the golf ball 116 . This, in turn, increases the effective contact area of the striking surface 112 with the golf ball 116 . In other words, the relatively extreme heel and toe weighting due to the weighted perimeter portions 138 and 140 extends or increases the “sweet spot” of the striking surface 112 . Accordingly, the weighted perimeter portions 138 and 140 thus allow the putter head 110 to be more forgiving and more effective at delivering a truer hit to the golf ball 116 when the point of contact between the golf ball 116 and the striking surface 112 does not coincide with the location of the center of mass of the putter head 110 .

- the rear surface 136 has at least one cavity or recessed portion 150 therein.
- a portion of the cavity 150 extends above the striking surface 112 so as to define the weighted perimeter portion 142 on the rear surface 136 .
- the recessed portion 150 defines at least one non-recessed portion 152 , which constitutes the weighted perimeter portion 142 of the rear surface 136 .
- the cavity 150 is generally centered between the heel portion 132 and the toe portion 134 of the golf putter head 110 .
- the rear surface 136 is shown having only one cavity 150 . It should be noted, however, that the rear surface 136 may be provided with any number of cavities, and these cavities can be shaped and positioned as necessary to locate the center of gravity 154 of the putter head 110 and provide the putter head 110 with a weighted distribution as desired.
- any of a wide range of geometric shapes may be used for the cavity 150 , such as circular shapes, triangular shapes, octagonal shapes, etc..
- the cavity 150 in FIG. 3 is substantially diamond-shaped, although other suitable shapes can be employed.
- the golf putter head 110 also includes weights 156 attached to the rear surface 136 .
- the weights 156 may have a density that is either higher, lower, or the same as the density of the rear surface 136 depending on the weight distribution that is desired for the putter head 110 .
- the weights 156 may be removably attached to the rear surface 136 . If removable, the weights 156 can be added and/or removed as desired even after the putter head 110 is manufactured.
- the weights 156 may also be positioned within a cavity (e.g., 150 ) defined in the rear surface 136 .
- the golf putter head 110 includes two weights 156 each of which is positioned within the diamond-shaped cavity 150 . Alternatively, other embodiments do not include weighted inserts, such as the golf putter head 910 shown in FIG. 15 .
- the weights 156 and weighted perimeter portions 138 and 140 distribute a substantial portion of the weight of the putter head 110 higher and wider than the golf ball 116 so as to better distribute the impact force between the striking surface 112 and the golf ball 116 . This, in turn, increases a golfer's opportunity at achieving a straighter and truer putt of the golf ball 116 with the putter head 110 .
- the various putter head features e.g., the striking surface 112 , reflective surface 114 , alignment surface 118 , weighted perimeter portions 138 , 140 142 , weights 156 , etc.
- the various putter head features are designed (e.g., sized, positioned, material selections, etc.) to position the center of gravity 154 for the putter head 110 as desired horizontally and vertically.
- the weighted perimeter portion 142 extends not only above the center of gravity 158 of the golf ball 116 but above the top edge 160 of the golf ball 116 as well when the golf ball 116 and putter head 110 are both resting on a generally horizontal or level putting surface 148 .
- the center of gravity 154 of the putter head 110 is located above the golf ball's center of gravity 158 .
- various embodiments include a center of gravity 154 of the putter head 110 which is located above the top edge 160 of the golf ball 116 as well when the golf ball 116 and putter head 110 are both positioned on the putting surface 148 .
- Positioning the putter head center of gravity 154 above the golf ball's center of gravity 158 enables the putter head 110 to more readily impart topspin and rolling to the golf ball 116 instead of causing the ball to skip and/or slide as is the case for putter heads which have a center of gravity lower than a center of gravity of a golf ball.
- the golf ball's center of gravity 158 is about 0.84 inches (2.13 centimeters) above the putting surface 148
- the golf ball's top edge 160 is about 1.68 inches (4.27 centimeters) above the putting surface 148 .
- the center of gravity 154 of the putter head 110 is preferably located a distance equal to or greater than about 1.00 inch (2.54 centimeters) above a bottom surface of the putter head 110 .
- the center of gravity 154 of the putter head 110 is preferably located a distance equal to or greater than about 1.00 inch (2.54 centimeters) above a level putting surface 148 when the putter head 110 is resting on a level putting surface 148 . Accordingly, the center of gravity 154 of the putter head 110 is above the golf ball's center of gravity 158 when the putter head 110 and golf ball 116 are both resting on a level putting surface 148 .
- the alignment surface 118 is preferably designed along with other putter head features (e.g., enhanced sidewall buttresses 138 and 140 , etc.) so as to move the putter head's center of gravity 154 further rearward from the striking surface 112 .
- the rearward location of the center of gravity 154 is rearward of a shaft hole 162 and shaft 164 (shown in phantom).
- the center of gravity 154 of the putter head 110 is preferably located behind the striking surface 112 a distance equal to or greater than about 1.00 inches (2.54 centimeters).
- the putter head 110 By having a more rearward center of gravity 154 which is above the golf ball's center of gravity 158 , the putter head 110 is able to impart a greater moment arm and thus greater roll distance, and more immediate rolling, to the golf ball 116 with less stroke power, e.g., with a softer and slower stroke. Because a slower and softer putting stroke is usually more easily controlled, the putter head 110 can improve a golfer's chances of maintaining a straight line during a putting stroke.
- the golf putter head can have a monolithic construction in which the golf putter head is integrally formed as a single component.
- the golf putter head may comprise two or more separate components that are secured to one another, for example, by welding, adhesives, and/or other suitable fastening methods.
- any one or more of the various golf putter heads 110 can include monolithic reflective and alignment surfaces (e.g., 114 and 118 , 214 and 218 , 314 and 318 , 414 and 418 , 514 and 518 , 614 and 618 , 714 and 718 , 814 and 818 , and 914 and 918 ).
- monolithic reflective and alignment surfaces e.g., 114 and 118 , 214 and 218 , 314 and 318 , 414 and 418 , 514 and 518 , 614 and 618 , 714 and 718 , 814 and 818 , and 914 and 918 ).
- the golf putter head 110 in FIGS. 1 through 7 includes monolithic reflective and alignment surfaces 114 and 118 which are integrally formed as a single component.
- the striking surface 112 and/or weights 156 can be separate components which are secured to the putter head 110 .
- the striking surface 112 is defined by a front surface of an insert formed of a material different than the putter head body, and the weights 156 comprise inserts formed of a heavier and higher density material than the material from which the monolithic reflective and alignment surfaces 114 and 118 are formed.
- the putter head 110 can be used as follows to statically align the putter head 110 with the golf ball 116 .
- a golfer positions the striking surface 112 adjacent the golf ball 116 so as to align the golf ball 116 with an axis passing through a center of a reflected golf ball image on the reflective surface 114 and to align the golf ball 116 and to align the indicator guide line 124 with the golf ball diameter perpendicular to the striking surface 112 .
- the indicator's guide line 124 and reflective surface's center guide line 128 can be used to indicate when the golfer's head is positioned directly over the putter head 110 , which is generally regarded as the proper head position for putting. More specifically, the guide lines 124 and 128 will appear as a single line to the downwardly looking golfer when the golfer's head is directly over the putter head 110 .
- Dynamic alignment of the putter head 110 with the golf ball 116 during a putting stroke can be maintained as follows. During the backswing, the reflected golf ball image visually travels up the reflective surface 114 . Conversely, the reflected golf ball image visually travels down the reflective surface 114 during the forward swing.
- the golfer keeps the moving image of the golf ball centered on the reflective surface 114 , and thus centered relative to the putter head 110 , during both the backswing and forward swing.
- the reflective surface 114 includes the guide lines 128 and 130 , as shown in FIG. 6 .
- the indicator guide line 124 can further assist the golfer in maintaining the dynamic alignment of the putter head 110 and the golf ball 116 during the putting stroke.
- the golfer can maintain the alignment by keeping the indicator guide line 124 aligned with the axis passing through the center of the moving reflected image of the golf ball 116 .

- Referring to
FIGS. 1 through 7 , there is shown a golf putter head, generally indicated byreference number 110, according to one embodiment of the present invention. Thegolf putter head 110 includes astriking surface 112 and areflective surface 114 which extends above thestriking surface 112. Thereflective surface 114 reflects an image of agolf ball 116 to a user when thestriking surface 112 is positioned adjacent thegolf ball 116. Thegolf putter head 110 further includes analignment surface 118 positioned behind thestriking surface 112. Thealignment surface 118 includes anindicator 120. As described in detail below, the reflective andalignment surfaces putter head 110 with thegolf ball 116. As used herein, the term “golf ball” shall be construed to include golf balls approved by the United States Golf Association (USGA) and golf balls approved by the Royal and Ancient Golf Club of St. Andrews. - In
FIG. 6 , thealignment surface 118 includes only onecircular indicator 120. Thecircular indicator 120 is sized such that its diameter is about equal, and preferably is equal, to the golf ball's diameter. In addition, the color of theindicator 120 can be white or other suitable color (e.g., yellow, pink, orange, etc.) so as to even further resemble a golf ball. - Alternatively, a wide range of other non-circular geometric shapes can be used for the indicator, including semicircular shapes, triangular shapes, rectangular shapes, etc. By way of example,
FIG. 8 illustrates an exemplarygolf putter head 210 having analignment surface 218 defining asemicircular indicator 220. In addition, the size of the indicator can also vary. - In addition, the alignment surface may define any number of (i.e., one or more) indicators which can vary in size and have diameters larger, smaller, and/or about equal to a golf ball diameter. For example,
FIG. 9 illustrates an exemplarygolf putter head 310 having a singlecircular indicator 320 with a diameter larger than the diameter of thegolf ball 316.FIG. 10 illustrates an exemplarygolf putter head 410 having acircular indicator 420 with a diameter smaller than the diameter of thegolf ball 416.FIG. 11 illustrates an exemplarygolf putter head 510 having two generallycircular indicators golf ball 516. - In various embodiments, the alignment surface and indicators can have a monolithic construction and be integrally formed as a single component. Alternatively, the alignment surface and indicator may comprise separate components in which case the indicator can be attached to the alignment surface, for example, by welding, adhesives, and/or other suitable fastening methods.
- As shown in
FIG. 6 , aguide line 124 is defined by theindicator 120. Theguide line 124 is aligned with a center of thestriking surface 112. Theguide line 124 is generally perpendicular to thestriking surface 112. - In a preferred embodiment, the
guide line 124 comprises a groove inscribed in theindicator 120. The groove is preferably highlighted or colored (e.g., with paint, etc.) so as to increase the contrast between theguide line 124 and the surface of theindicator 120, thus making theguide line 124 more readily visible. - Alternatively, the indicator and guide line can be separate components in which case the guide line can engaged to the indicator, for example, by welding, adhesive, and/or other suitable fastening methods. Still further embodiments include a
golf putter head 610 which does not have a guide line defined by theindicator 620, as shown inFIG. 12 . - With reference to
FIGS. 1 through 6 , thereflective surface 114 reflects an image of agolf ball 116 to a user when thestriking surface 112 is positioned adjacent thegolf ball 116. Thereflective surface 114 is preferably muted so to render theputter head 110 in compliance with USGA rules. By way of example only, an exemplary embodiment includes areflective surface 114 which has been roughened so as to mute the reflective properties of thesurface 114. In another embodiment, a coating can be applied to thereflective surface 114 with the coating decreasing the reflective nature of thesurface 114. - The
reflective surface 114 includes acenter guide line 128 positioned between two diverging guide lines 130. Thecenter guide line 128 is positioned relative to theindicator guide line 124 such that the twolines putter head 110 when the golfer's head is directly over theputter head 110, which is generally regarded as the proper head position for putting. - In some embodiments, however, the reflective surface does not include a center guide line and/or diverging guide lines. For example,
FIG. 13 illustrates an exemplarygolf putter head 710 in which thereflective surface 714 includes acenter guide line 728 but not diverging guide lines. - Further, the entire surface extending above the
striking surface 112 is reflective inFIG. 1 . In other embodiments, however, such is not the case. For example,FIG. 14 illustrates an exemplarygolf putter head 810 in which thereflective surface 814 is disposed only between the diverging guide lines 830. Thereflective surface 814 reflects animage 817 of a portion of thegolf ball 816. Theportion 815 outside theguide lines 830 is not reflective as represented by the speckles. - Referring now to
FIG. 3 , thegolf putter head 110 further includes aheel portion 132, atoe portion 134, and arear surface 136 positioned opposite (i.e., on a backside of) thestriking surface 112 and thereflective surface 114. Thegolf putter head 110 also includes aweighted perimeter portion 138 adjacent theheel portion 132 and aweighted perimeter portion 140 adjacent thetoe portion 134. - In the illustrated embodiment, the
weighted perimeter portions golf ball 116. This, in turn, increases the effective contact area of thestriking surface 112 with thegolf ball 116. In other words, the relatively extreme heel and toe weighting due to theweighted perimeter portions striking surface 112. Accordingly, theweighted perimeter portions putter head 110 to be more forgiving and more effective at delivering a truer hit to thegolf ball 116 when the point of contact between thegolf ball 116 and thestriking surface 112 does not coincide with the location of the center of mass of theputter head 110. - The
rear surface 136 also includes a weighted perimeter portion 142 which extends above thestriking surface 112, shown in phantom inFIG. 3 . In the illustrated embodiment ofFIGS. 1 through 7 , the weighted perimeter portion 142 extends along bothsides golf ball 116 when thestriking surface 112 is positioned adjacent thegolf ball 116 on the puttingsurface 148. The weighted perimeter portion 142 also extends substantially from theheel portion 132 to thetoe portion 134. The weighted perimeter 142 may also extend above and substantially around an upper hemisphere of thegolf ball 116 when thestriking surface 112 is positioned adjacent thegolf ball 116 sitting on the puttingsurface 148. - As shown in
FIG. 3 , therear surface 136 has at least one cavity or recessedportion 150 therein. A portion of thecavity 150 extends above thestriking surface 112 so as to define the weighted perimeter portion 142 on therear surface 136. Stated differently, the recessedportion 150 defines at least one non-recessed portion 152, which constitutes the weighted perimeter portion 142 of therear surface 136. In one embodiment, thecavity 150 is generally centered between theheel portion 132 and thetoe portion 134 of thegolf putter head 110. - In
FIG. 3 , therear surface 136 is shown having only onecavity 150. It should be noted, however, that therear surface 136 may be provided with any number of cavities, and these cavities can be shaped and positioned as necessary to locate the center ofgravity 154 of theputter head 110 and provide theputter head 110 with a weighted distribution as desired. In addition, any of a wide range of geometric shapes may be used for thecavity 150, such as circular shapes, triangular shapes, octagonal shapes, etc.. By way of example only, thecavity 150 inFIG. 3 is substantially diamond-shaped, although other suitable shapes can be employed. - In the illustrated embodiment, the
golf putter head 110 also includesweights 156 attached to therear surface 136. Theweights 156 may have a density that is either higher, lower, or the same as the density of therear surface 136 depending on the weight distribution that is desired for theputter head 110. Theweights 156 may be removably attached to therear surface 136. If removable, theweights 156 can be added and/or removed as desired even after theputter head 110 is manufactured. Theweights 156 may also be positioned within a cavity (e.g., 150) defined in therear surface 136. In the preferred embodiment, thegolf putter head 110 includes twoweights 156 each of which is positioned within the diamond-shapedcavity 150. Alternatively, other embodiments do not include weighted inserts, such as thegolf putter head 910 shown inFIG. 15 . - Preferably, the
weights 156 andweighted perimeter portions putter head 110 higher and wider than thegolf ball 116 so as to better distribute the impact force between thestriking surface 112 and thegolf ball 116. This, in turn, increases a golfer's opportunity at achieving a straighter and truer putt of thegolf ball 116 with theputter head 110. - Further, the various putter head features (e.g., the
striking surface 112,reflective surface 114,alignment surface 118,weighted perimeter portions weights 156, etc.) are designed (e.g., sized, positioned, material selections, etc.) to position the center ofgravity 154 for theputter head 110 as desired horizontally and vertically. In the embodiment shown inFIGS. 1 through 6 , the weighted perimeter portion 142 extends not only above the center ofgravity 158 of thegolf ball 116 but above thetop edge 160 of thegolf ball 116 as well when thegolf ball 116 andputter head 110 are both resting on a generally horizontal orlevel putting surface 148. - As best shown in
FIGS. 4 and 5 , the center ofgravity 154 of theputter head 110 is located above the golf ball's center ofgravity 158. Indeed, various embodiments include a center ofgravity 154 of theputter head 110 which is located above thetop edge 160 of thegolf ball 116 as well when thegolf ball 116 andputter head 110 are both positioned on the puttingsurface 148. - Positioning the putter head center of
gravity 154 above the golf ball's center ofgravity 158 enables theputter head 110 to more readily impart topspin and rolling to thegolf ball 116 instead of causing the ball to skip and/or slide as is the case for putter heads which have a center of gravity lower than a center of gravity of a golf ball. - With further reference to
FIGS. 4 and 5 , the golf ball's center ofgravity 158 is about 0.84 inches (2.13 centimeters) above the puttingsurface 148, whereas the golf ball'stop edge 160 is about 1.68 inches (4.27 centimeters) above the puttingsurface 148. The center ofgravity 154 of theputter head 110 is preferably located a distance equal to or greater than about 1.00 inch (2.54 centimeters) above a bottom surface of theputter head 110. Stated differently, the center ofgravity 154 of theputter head 110 is preferably located a distance equal to or greater than about 1.00 inch (2.54 centimeters) above alevel putting surface 148 when theputter head 110 is resting on alevel putting surface 148. Accordingly, the center ofgravity 154 of theputter head 110 is above the golf ball's center ofgravity 158 when theputter head 110 andgolf ball 116 are both resting on alevel putting surface 148. - In addition, the
alignment surface 118 is preferably designed along with other putter head features (e.g., enhanced sidewall buttresses 138 and 140, etc.) so as to move the putter head's center ofgravity 154 further rearward from thestriking surface 112. In the exemplary embodiment shown inFIGS. 4 and 5 , the rearward location of the center ofgravity 154 is rearward of ashaft hole 162 and shaft 164 (shown in phantom). Still referring to the exemplary embodiment ofFIGS. 4 and 5 , the center ofgravity 154 of theputter head 110 is preferably located behind the striking surface 112 a distance equal to or greater than about 1.00 inches (2.54 centimeters). - By having a more rearward center of
gravity 154 which is above the golf ball's center ofgravity 158, theputter head 110 is able to impart a greater moment arm and thus greater roll distance, and more immediate rolling, to thegolf ball 116 with less stroke power, e.g., with a softer and slower stroke. Because a slower and softer putting stroke is usually more easily controlled, theputter head 110 can improve a golfer's chances of maintaining a straight line during a putting stroke. - In various embodiments, the golf putter head can have a monolithic construction in which the golf putter head is integrally formed as a single component. Alternatively, the golf putter head may comprise two or more separate components that are secured to one another, for example, by welding, adhesives, and/or other suitable fastening methods.
- For example, any one or more of the various golf putter heads 110 (
FIGS. 1 through 7 ), 210 (FIG. 8 ), 310 (FIG. 9 ), 410 (FIG. 10 ), 510 (FIG. 11 ), 610 (FIG. 12 ), 710 (FIG. 13 ), 810 (FIG. 14 ), 910 (FIG. 15 ) can include monolithic reflective and alignment surfaces (e.g., 114 and 118, 214 and 218, 314 and 318, 414 and 418, 514 and 518, 614 and 618, 714 and 718, 814 and 818, and 914 and 918). - By way of example only, the
golf putter head 110 inFIGS. 1 through 7 includes monolithic reflective andalignment surfaces striking surface 112 and/orweights 156, however, can be separate components which are secured to theputter head 110. In an exemplary embodiment, thestriking surface 112 is defined by a front surface of an insert formed of a material different than the putter head body, and theweights 156 comprise inserts formed of a heavier and higher density material than the material from which the monolithic reflective andalignment surfaces - The
putter head 110 can be used as follows to statically align theputter head 110 with thegolf ball 116. At address, a golfer positions thestriking surface 112 adjacent thegolf ball 116 so as to align thegolf ball 116 with an axis passing through a center of a reflected golf ball image on thereflective surface 114 and to align thegolf ball 116 and to align theindicator guide line 124 with the golf ball diameter perpendicular to thestriking surface 112. - Further, the indicator's
guide line 124 and reflective surface'scenter guide line 128 can be used to indicate when the golfer's head is positioned directly over theputter head 110, which is generally regarded as the proper head position for putting. More specifically, theguide lines putter head 110. - Dynamic alignment of the
putter head 110 with thegolf ball 116 during a putting stroke can be maintained as follows. During the backswing, the reflected golf ball image visually travels up thereflective surface 114. Conversely, the reflected golf ball image visually travels down thereflective surface 114 during the forward swing. - Ideally, the golfer keeps the moving image of the golf ball centered on the
reflective surface 114, and thus centered relative to theputter head 110, during both the backswing and forward swing. To assist the golfer with this feat, thereflective surface 114 includes theguide lines FIG. 6 . By keeping the moving reflected image of thegolf ball 116 centered along thecenter guide line 128 and/or between theguide lines 130, the golfer is able to keep theputter head 110 dynamically aligned with thegolf ball 116. - In addition, the
indicator guide line 124 can further assist the golfer in maintaining the dynamic alignment of theputter head 110 and thegolf ball 116 during the putting stroke. The golfer can maintain the alignment by keeping theindicator guide line 124 aligned with the axis passing through the center of the moving reflected image of thegolf ball 116. - The description of the invention is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. Thus, variations that do not depart from the substance of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
