1. Field of the Invention

The present invention relates to an alignment invention for putting. More specifically, the present invention relates to a golf ball having an alignment indicia.

2. Description of the Related Art

Putting is a very difficult, if not the most difficult part of the game of golf. When attempting to putt a golf ball into a hole on a green, the golfer attempts to align the direction of the golf ball with the hole, and to putt toward the hole. However, the golfer is above the golf ball and his or her visual perception is skewed allowing for misperception of the exact direction he or she should putt the golf ball.

The golf industry has provided alignment devices in the past to assist golfers with putting, and aligning a golf ball with the hole. One example is set forth in U.S. Pat. No. 4,928,971 for an Alignment System that discloses markings on a putter which include a first line, a second line perpendicular to the first line, and a conical depression.

Another example is the SEEMORE® putter which is disclosed in U.S. Pat. No. 5,564,990 and at www.seemore.com. The alignment markings of the SEEMORE® putter include two parallel lines that border a circular marking which is screened from view if the golfer is properly aligned.

Yet another example is set in U.S. Pat. No. 5,174,573 for a Putter Having A Head With Ball-Centering Indicia which discloses a curvilinear reference on the crown of the putter. Another example is Inoue, U.S. Pat. No. 4,706,958. Inoue discloses a golf ball that is capable of being stroked in the direction of its center of gravity by providing markings on the golf ball.

However, the prior art fails to disclose a golf ball that allows for more accurate putting.

The present invention provides a solution to more accurate putting without departing from the Rules of Golf. The present invention marks a golf ball with alignment indicia to allow a golfer to properly place the golf ball in direction toward a hole. The golf ball also has marking thereon for aligning with a face of a putter for proper putting.

Having briefly described the present invention, the above and further objects, features and advantages thereof will be recognized by those skilled in the pertinent art from the following detailed description of the invention when taken in conjunction with the accompanying drawings.

As shown in FIG. 1, a golf ball 22 is marked with alignment indicia 26 and a putter 24 may be marked with alignment indicia 28 to provide a typical golfer with a means to more accurately putt the golf ball 22 into a hole. The golf ball 22 may be a typical golf ball, preferably having a diameter of approximately 1.68 inches or greater since USGA Rules dictate such a diameter for the golf ball. However, those skilled in the pertinent art will recognize that golf balls with smaller diameter may be used without departing from the scope and spirit of the present invention.

The golf ball 22 preferably has a white surface, however, other colors may be used for the surface of the golf ball 22 . The golf ball 22 is preferably a three-piece solid golf ball, however, two-piece, four-piece, wound, hollow core and liquid-filled core golf balls may also be used for practicing the present invention. The cover of the golf ball 22 may be composed of an ionomer, balata (transpolyisoprene), polyurethane or similar polymer material. The cover is typically coated with a base coat (typically pigmented) and/or a clear top coat.

The alignment indicia 26 is printed on the surface of the golf ball 22 . The alignment indicia 26 is preferably printed on a base coat with a top coat applied over the alignment indicia 26 . However, in an alternative embodiment the alignment indicia 26 is printed on the top coat of the golf ball 22 .

The alignment indicia 26 is composed of a longitudinal segment 30 and a latitudinal segment 32 , and optionally a pole indicia 34 . The longitudinal segment 30 is typically a straight line across the pole 33 of the golf ball 22 . The pole indicia 34 is printed on the pole 33 to indicate the top of the golf ball 22 . The golf ball 22 has a top pole 33 and a bottom pole 33 a , not shown, which are each an equal distance from an equator 35 of the golf ball 22 . The equator 35 typically lies on a seam line of the golf ball 22 which is indicative of the seam buffing of molding remnants that remain on the golf ball 22 after de-molding during processing of the golf ball 22 .

As shown in FIG. 12, the longitudinal segment 30 preferably extends from 1.00 inch to 1.5 inches across the pole 33 of the golf ball 22 , with the pole 33 preferably dividing the longitudinal segment 30 into two equal portions. A preferred length of the longitudinal segment 30 is 1.35 inches, with the midpoint of the longitudinal segment 30 lying on the top pole 33 of the golf ball. The longitudinal segment 30 provides the golfer with a visual straight line to align the golf ball 22 with the hole on the green. Also, the pole indicia 34 allows the golf ball 22 to be properly placed with the very top of the golf ball 22 , the top pole 33 , perpendicular to the ground.

The latitudinal segment 32 preferably ranges from 0.5 inch to 2.0 inches in length. Both the latitudinal segment and the longitudinal segment have a width the ranges from 0.075 inch to 0.140 inch. Visually, the latitudinal segment 32 is perpendicular or substantially perpendicular to the longitudinal segment 30 . Visually, the latitudinal segment 32 is parallel or substantially parallel to the alignment indicia 28 of the putter 24 . The latitudinal segment 32 provides the golfer with a visual straight line to strike the golf ball 22 with the putter 24 thereby hopefully providing a straighter putt.

However, as shown in FIG. 13, the latitudinal segment 32 is curved along the spherical surface of the golf ball 22 when viewed from a plan view of the equator 35 . The radius of curvature, R, of the latitudinal segment 32 preferably ranges from 0.450 inch to 0.650 inch, with a preferred radius of curvature of 0.550 inch.

The curvature of the golf ball 22 allows for variation in the alignment indicia 26 , especially the latitudinal segment 32 . One embodiment of the golf ball 22 of the present invention is shown in FIGS. 2-4. FIG. 2 is a front view of a golf ball 22 , FIG. 3 is a view of the golf ball 22 rotated ninety degrees, and FIG. 4 is a view of the golf ball rotated an additional ninety degrees. In this embodiment, there is a first longitudinal segment 30 a intersected by a first latitudinal segment 32 a . The golf ball 22 also has a first logo indicia 36 a which includes typical markings that are printed on a golf ball 22 to designate origin of the golf ball 22 . The golf ball 22 also has a second longitudinal segment 30 b intersected by a second latitudinal segment 32 b , along with a second logo indicia 36 b . The first and second latitudinal segments 32 a-b are semi-circles with a mid-point respectively intersecting first and second longitudinal segments 30 a-b . During putting, a golfer would position the golf ball 22 of this embodiment as shown in FIG. 3 when viewed from directly above. Thus, the curved latitudinal 32 a appears to be a straight line. The latitudinal segment 32 is positioned so as to be as close to a face 39 of a putter 24 while still being viewed from above as a straight line.

Another embodiment of the golf ball 22 of the present invention is shown in FIGS. 5-7. FIG. 5 is a front view of a golf ball 22 , FIG. 6 is a view of the golf ball 22 rotated ninety degrees, and FIG. 7 is a view of the golf ball rotated an additional ninety degrees. In this embodiment, the first longitudinal segment 30 a intersects the first latitudinal segment 32 a and the second latitudinal segment 32 b . The golf ball 22 also has a first logo indicia 36 a which is encircled by the first latitudinal segment 32 a . The golf ball 22 also has a second longitudinal segment 30 b which intersects the first latitudinal segment 32 a and the second latitudinal segment 32 b . The second latitudinal segment 32 b encircles a second logo indicia 36 b . The first and second latitudinal segments 32 a-b are circles that intersect the first and second longitudinal segments 30 a-b at points that are one-hundred eighty degrees from each other. During putting, a golfer would position the golf ball 22 of this embodiment as shown in FIG. 6 when viewed from directly above. Thus, the circular latitudinal segment 32 a appears to be a straight line.

Other embodiments of the golf ball 22 of the present invention are illustrated in FIGS. 8-11. The golf balls 22 of FIGS. 8 and 9 utilize logo indicia for the longitudinal segment 30 and the latitudinal segment 32 . In such embodiments, the logo indicia is composed of letters and or symbols positioned accordingly to create the longitudinal segment 30 and the latitudinal segment 32 . The golf balls 22 of FIGS. 10 and 11 utilize a pole indicia 34 with lines for the longitudinal segment 30 and latitudinal segment 32 . Those skilled in the relevant art will recognize numerous other variations for the alignment indicia 26 which may be utilized without departing from the scope and spirit of the present invention.

The application of the alignment indicia 26 is preferably accomplished through use of a pad-printing system that utilizes an ultraviolet light curable ink. However, those skilled in the pertinent art will recognize that other printing systems may be utilized to apply the alignment indicia 26 without departing from the scope and spirit of the present invention.

Returning to FIG. 1, the putter 24 is typically composed of a face 39 , a hosel 40 , a crown 42 , a heel end 46 , a toe end 48 and a sole 50 . The putter may be a blade type putter or an insert type putter such as an ODYSSEY® putter from Callaway Golf Company of Carlsbad, Calif. The alignment indicia 28 is printed, embossed, painted or in some other manner applied to the crown. In a preferred embodiment, the alignment indicia 28 includes a longitudinal segment 52 and a latitudinal segment 54 . An alternative embodiment of the alignment indicia 28 only includes the latitudinal segment 54 . The latitudinal segment generally ranges from 0.75 inch to 2.0 inches in length, and is disposed on the crown 42 nearest the face 39 of the putter 24 . The optional longitudinal segment 52 is generally perpendicular to the latitudinal segment 54 , and is applied on the crown 42 on substantially the mid-point of the putter 24 between the heel end 46 and the toe end 48 . The length of the longitudinal segment 52 ranges from 0.25 inch to 2.00 inches depending on the width of the crown 42 of the putter 24 .

The placement of the putter alignment indicia 28 allows a golfer to align the putter 24 with the properly aligned golf ball 22 to putt in a manner that should result in more accurate putts. The golfer need only align the putter alignment indicia 28 with the golf ball alignment indicia 26 in order to ensure a straight putt without visual misinterpretation of the putting of the golf ball 22 toward a hole in a green.

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. Therefore, the embodiments of the invention in which an exclusive property or privilege is claimed are defined in the following appended claims.
