Golf putter headGolf putter head description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20070243943, Golf putter head. Brief Patent Description - Full Patent Description - Patent Application Claims
REFERENCE TO RELATED APPLICATION [0001]This non-provisional patent application is based upon U.S. Provisional Patent Application Ser. No. 60/791,995 filed Apr. 14, 2006 and hereby claims the benefit of the filing date thereof. BACKGROUND OF THE INVENTION [0002]The present invention is related to golf equipment and, in particular, to a golf putter head with enhanced weight distribution, selectable weights, movable center of gravity, target and address alignment aids, and ball hitting projections that enhance feel, acoustics and ball anti-skid properties. [0003]Heretofore, golf putter heads with adjustable weight members often included extraneous parts such as spacers, springs, magnets, fillers and the like that immobilized weight members in a single longitudinal bore. Other designs included multiple threaded bores which received selectable weights but did not provide infinite adjustability of the center of gravity. A non-bore design often utilized a channel or a cavity within which resided a sliding securable weight. Yet another design used extruding posts with interchangeable washers. The prior art as disclosed in U.S. Pat. Nos. 1,343,998 to Grant, 2,998,254 to Rains et al, 3,979,122 to Belmont, 4,962,932 to Anderson, 6,015,354 to Ahn, 5,244,210 to Au, and 6,001,024 to Van Alen shows a putter head with a single threaded bore that required spacers and the like to secure the weights. U.S. Pat. Nos. 1,840,924 to Tucker and 4,828,266 to Tunstall show two longitudinal single-opening threaded bores at the extremities that used spacers to immobilize the weight members. U.S. Pat. Nos. 4,213,613 to Nygren and 6,348,014 to Chiu show lateral threaded bores at the heel end and the toe end of the putter head that allow for weight selection but lacked longitudinal heel-toe positioning. U.S. Pat. No. 5,769,737 to Holladay discloses adjustability of a sliding weight housed in a cavity. U.S. Pat. No. 7,074,132 to Finn and publication US2003/0220150 A1 to Takase disclose fixed weight members spaced from the face portion but does not include adjustable weights. [0004]Heretofore, golfer address position aids usually utilized references at two elevations on the putter head. The prior art U.S. Pat. Nos. 6,200,227 to Sery, 6,394,910 to McCarthy, and 5,921,868 to DiMartino disclose golfer head alignment aids that utilize alignment references at two elevations which the eyes align to thereby ensure a repeatable address position. U.S. Pat. No. 5,913,731 to Westerman discloses a ball-width contour alignment channel but the channel lacks the vertical sides necessary for head address alignment, and also said channel is not defined by spaced weight-carrying portions. U.S. Pat. No. 6,692,378 to Shmoldas discloses an alignment channel with vertical sides but the channel is also not defined by stand-alone spaced weight-carrying portions. [0005]Heretofore, alignment aids that indicate a golf ball such as disks, circles, arcs and hemispheres are disclosed in U.S. Pat. Nos. 3,343,839 to Borah, 3,708,172 to Rango, 3,779.398 to Hunter, 3,884,477 to Bianco, and 4,688,798 to Pelz all include a visible structural support member when viewed squarely from above. The distracting support member makes it more difficult for the various alignment aids to simulate a freestanding golf ball. A freestanding "virtual" golf ball alignment aid provides for easy alignment of the putter head, ball and target. [0006]Heretofore, putter face markings or face inserts did not include high density positive sloped projections. U.S. Pat. Nos. 6,849,004 to Lindsay, 5,709,616 to Rife, and 5,637,044 to Swash all disclose parallel ridges and/or grooves in different configurations and patterns. Putter face markings with vertical freestanding projections include U.S. Pat. Nos. D411,275 to Bottema, D63,284 to Challis, 4,964,641 to Miesch and 6,257,994 to Antonious wherein the ball-impacting projections are either cylindrical, cubed, rectangular or diamond shaped, but all lack the positive sloped side support structure that is essential for the making of small projections for a high dots per inch pattern. U.S. Pat. No. 6,007,434 to Baker discloses an insert that is comprised of mechanically made truncated pyramid shaped projections of low dots per inch; U.S. Pat. No. 4,964,641 to Miesch discloses large 0.040'' on center pyramids, and U.S. Pat. No. 6,089,993 to Woodward discloses cylindrical projections. BRIEF SUMMARY OF THE INVENTION [0007]It is the objects of the present invention to provide an improved golf putter that provides for forgiveness on miss hits, provides for a simple system to select and adjust weight members, provides references for target and golfer address alignment, and provides for an enhancement in feel and golfer confidence. Accordingly, the objective of a more forgiving putter entails a greater moment of inertia and that is accomplished by dense heel and toe weight members spaced rearward from the face portion. The objective to provide a simple adjustable weight system is accomplished by having selectable dense weight members housed in a chamber movably securable with end plug setscrews, and without the need for spacers, springs, and fillers. The objective of easy target alignment is accomplished by the stand-alone spaced weight-carrying portions defining a ball-width alignment channel wherein said channel is disposed with parallel markings for tangential alignment with the golf ball, or in an alternate embodiment, alignment is provided by an optically isolated alignment disk that has no visible support member and therein becomes a "virtual" golf ball. The objective of repeatable heel-to-toe, here forth called longitudinal, golfer head alignment is accomplished by the parallax properties of the inboard vertical sides of the alignment channel. Correspondingly, the objective of repeatable target-to-putter head, here forth called lateral, golfer head alignment is accomplished by the visible part line on the surface of the weight-carrying portions wherein said part line is located at the inflexion point defined by a vertical tangent. The objective of enhanced feel is accomplished by the sensing of the spaced weight members by using a thin sole section that connects the face portion to the spaced weight-carrying portions, by the isolated face portion, and by the enhanced audible feedback of a struck ball due to the small dense face projections. The objective of increased confidence is accomplished by the customization of the adjustable weights, easy alignment, and an aesthetically functional putter head.
