- the club head such as a putter head, will preferably have the mass of the club distributed in the horizontal plane, rather than being concentrated at the center of mass. This distribution increases the moment of inertia of the club in the horizontal plane and increases the effective size of the “sweet spot” on the club face.
- the club is thus more effective at delivering a true hit, even if contact with the ball is off of the location of the center of mass of the club head.

- a golf putter head or club head 110 in accordance with the present invention has a club head body 111 which is preferably constructed from a low density material, for example a plastic such as a high density polypropylene or similar material.
- the club head 110 may be fastened to a shaft 112 mounted in shaft hole 114 , as known in the art.
- the club head may be provided with specific inserts 115 , 116 , and 118 of higher density material, such as lead, aluminum, brass or stainless steel.
- the particular materials may be chosen to suit the preference of the individual golfer. A harder material for insert 115 will impart a sharper impact to the ball, on contact. A softer material will impart a softer impact to the ball, on contact.
- club head 110 and club head body 111 may be produced out of a higher density material, such as stainless steel, aluminum or brass.
- the club head 110 may also us a lower density insert 115 in the front cavity 119 , for example, a plastic material such as high density polypropylene or equivalent.
- Inserts 115 , 116 , and 118 are located to provide and enhance specific club head functions.
- insert 115 in the front face of the club head 110 functions as the primary striking surface.
- Insert 115 provides a small concentrated area of weight and mass in the vertical plane.
- the vertical dimension of insert 115 preferably is smaller than the diameter of a golf ball 120 . This focuses more of the force of impact into the ball and results in a more straight and true putt with less of a club stroke.
- the horizontal dimension of insert 115 is extended to increase the moment of inertia of the club head 110 in the horizontal plane; this extends the “sweet spot” of the club head and assists in providing a true hit when the ball is struck off center.
- Insert 115 also preferably is formed of material having a specific “coefficient of restitution.” This material may be tailored to the preference of the user. A particular user may be comfortable with a very hard insert 115 , which provides a sharp impact on contact with the ball. Another user may be comfortable with a soft insert 115 , which provides a soft impact on contact with the ball. The features preferred by the user can assist in providing consistent straight and true putts.
- Front insert 115 is sized and located to work with other inserts 116 and 118 in producing a specifically located center of gravity that ensures a more straight and true putt.
- Specific inserts 116 and 118 are also located from the rear of club head 110 in sockets 117 . For example, these inserts are located to work with front insert 115 and produce a specific center of gravity.
- Inserts 116 and 118 are located at the top of a vertically rising structure 122 starting directly above the small contact area of the club face, and gradually expanding in width as it rises and curves back along a geometric path. Inserts 116 and 118 are located at the top of the vertically rising structure 122 . Inserts 116 and 118 provide a counterbalancing effect for the club. Since they are located wider and higher than golf ball 120 , the force of impact between club head 110 and golf ball 120 is better distributed. This permits the club head 110 to swing through more smoothly and increases the opportunity for a straight and true putt. Vertically rising structure 122 is preferably made of a lower density material, and thus is flexible.
- the vertically rising structure flexes like a spring, absorbing the golf ball impact.
- the system behaves like a “spring/damper,” increasing the chance of an uninterrupted smooth swing and increasing the opportunity for a straight and true putt.
- Vertically rising structure 122 gradually expands in width as it rises and curves back along a geometric path. When vertically rising structure 122 is viewed from above as seen in FIG. 6 , it takes the shape of an arrowhead 124 . This results in a dramatically improved way of aligning club head 110 along a prescribed path towards a hole or pin 126 ; the construction of club head 110 , using vertically rising structure 122 is especially useful as a training device and as a practice tool to develop a good putting stroke. More particularly, vertically rising structure 122 allows the golfer to match the rear curve of arrowhead 124 with the rear curve of body 111 for perfect alignment of club head 110 with ball 120 .
- a front surface 128 of vertically rising structure 122 has a tapered center reflective surface, for example formed of sputter coated aluminum, that allows the golfer to visually align golf ball 120 , with a reflection 130 of the golf ball and a reflection 132 of hole or pin 126 as shown in FIG. 5 .
- Front surface 128 of vertically rising structure 122 can be flat or preferably slightly curved in its third dimension, as shown.

These can include golf tees, golf divot repair tools and golf ball markers, not shown. If club head 110 is produced out of a higher density material, using a lower density insert 115 in the front cavity, the club head still has the advantages of the vertically rising structure 122 and inserts 116 and 118 above the plane of the ball.

Abstract
A golf club (110) has a head (111) with a curved reflective surface (128) for visually aligning a shot. The club head is counterbalanced above the plane of the ball (120) and has balance weights (116, 118) which may be selected to accommodate the style and preference of the user. The striking surface may be of a different material than the surrounding club head to dampen vibration on the stroke and may be of a material tailored to the user's preference. The other parts of the club may also be composites of several materials to assist in dampening vibration. An alternative aligning structure uses lenticular lens (142, 144, 146) to provide guiding images to the user.

FIGS. 1 and 3 , a golf putter head orclub head 110 in accordance with the present invention has a club head body 111 which is preferably constructed from a low density material, for example a plastic such as a high density polypropylene or similar material. Theclub head 110 may be fastened to ashaft 112 mounted inshaft hole 114, as known in the art. The club head may be provided withspecific inserts insert 115 will impart a sharper impact to the ball, on contact. A softer material will impart a softer impact to the ball, on contact. It will be understood, however, thatclub head 110 and club head body 111 may be produced out of a higher density material, such as stainless steel, aluminum or brass. Theclub head 110 may also us alower density insert 115 in thefront cavity 119, for example, a plastic material such as high density polypropylene or equivalent. - Higher density inserts 115, 116, and 118 are located to provide and enhance specific club head functions. For example, insert 115 in the front face of the
club head 110 functions as the primary striking surface.Insert 115 provides a small concentrated area of weight and mass in the vertical plane. The vertical dimension ofinsert 115 preferably is smaller than the diameter of agolf ball 120. This focuses more of the force of impact into the ball and results in a more straight and true putt with less of a club stroke.

This permits theclub head 110 to swing through more smoothly and increases the opportunity for a straight and true putt. Vertically risingstructure 122 is preferably made of a lower density material, and thus is flexible. Withinserts - Vertically rising
structure 122 gradually expands in width as it rises and curves back along a geometric path. When vertically risingstructure 122 is viewed from above as seen inFIG. 6 , it takes the shape of anarrowhead 124. This results in a dramatically improved way of aligningclub head 110 along a prescribed path towards a hole orpin 126; the construction ofclub head 110, using vertically risingstructure 122 is especially useful as a training device and as a practice tool to develop a good putting stroke. More particularly, vertically risingstructure 122 allows the golfer to match the rear curve ofarrowhead 124 with the rear curve of body 111 for perfect alignment ofclub head 110 withball 120. - A

Asclub head 110 is stroked,reflections mirror surface 128, and within the divergingcurved boundary lines 129, shown inFIG. 1 ; if they do not, then the golfer is not stroking along the correct path towards the hole. Correction is made by changing the stance and club alignment to correctly position the image ofreflections mirror surface 128. - When
club head 110 is made out of a low density material, such as injection moldable plastic, it has the enhanced ability to have “snap fit” details molded into its shape. For example, there can be “snap” details on the rear of vertically protruding vertically risingstructure 122 that can hold certain golf accessories. These can include golf tees, golf divot repair tools and golf ball markers, not shown. Ifclub head 110 is produced out of a higher density material, using alower density insert 115 in the front cavity, the club head still has the advantages of the vertically risingstructure 122 and inserts 116 and 118 above the plane of the ball. As shown inFIG. 3 , vertically risingstructure 122 may be provided with strengtheningwebs webs form cavities structure 122, as shown.Cavities Cavities club head 110 to suit the style and preference of the club user. Also as shown inFIG. 3 , insert 115 may be held incavity 119 byfasteners Fasteners - It will be appreciated that the various elements described herein, such as
inserts machine screws club head 110 and still permit the elements ofclub head 110 to be interchanged to suit the preferences of the user. For example, insert 115 may be replaced by the user to compensate for wear or breakage or to interchange hard or soft striking surfaces, i.e., brass, lead or plastic. The construction ofclub head 110 may also be made substantially permanent, if desired. For example, a substantially permanent adhesive, such as a catalytic epoxy or equivalent, may be used to join the elements ofclub head 110. - Referring to
FIG. 2 , an alternative embodiment is shown which has a further alternative aligning guide means. In this construction, alignment is provided by reference to a set of reflective elements or lens, 142, 144 and 146 which are mounted on the upper surface ofclub head 110, as shown, for example by an adhesive, as known in the art. Preferablyelements lens club head 110, the proper position for putting. When the user looks down at theclub head 110 the three images fromlenses - The image viewed by the golfer, when in position, can be color or other indicia such as parallel arrows indicating the direction of the club stroke.
