## Background
RELATED U.S. APPLICATION DATA
The present application is a non-provisional application claiming priority from U.S. Provisional Patent Application Ser. No. 62/379,189 filed on Aug. 24, 2016 by Eric Sillies and entitled GOLF CLUB HEAD, the full disclosure of which is hereby incorporated by reference.


FIELD OF THE INVENTION
The present disclosure relates generally to a golf club head for a golf club.
BACKGROUND OF THE INVENTION
Golf is a sport enjoyed by golfers of all ages and skill levels. Golfers at all levels continually strive to improve their game. One approach that many golfers use to improve their play is to customize their clubs to fit their game. Golf presents many challenges to golfers. For example, many golfers find their game changing over time. Additionally, golf courses present a variety of challenging holes that provide golfers the opportunity to use golf clubs of varying features and/or characteristics to best meet such challenges. As a result, golfers require a variety of different clubs to meet these challenges.
Although golfers may desire a large number of different clubs for their game, many practical considerations can prevent golfers from meeting this need. The 14 club rule in the Rules of Golf limits the number of clubs golfers can carry. Players, who prefer to carry their bags, often prefer to limit the number of clubs they carry to make the round more enjoyable and carrying their golf bag less burdensome. Another consideration is cost. Although players may desire three different drivers having different characteristics, many golfers simply can't justify the expense of purchasing such clubs.
Thus, a continuing need exists for a golf club that can be easily, simply and conveniently adjusted to obtain different golf club characteristics. What is needed is a golf club that performs well, and allows for the player to quickly and easily adjust the club head to match the golfer's particular needs or objectives at that time. There is a need for a club head that can be readily adjusted into a variety of different settings thereby eliminating the need for the golfer to carry multiple clubs to meet the different desired settings. Further, there is a need for a golf club that meets these needs while also providing an improved, pleasing aesthetic.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
FIGS. 1 through 20 illustrate an example golf club is indicated generally at 10. The golf club 10 of FIG. 1 is configured as a driver. The various features of the example golf club 10 can also be formed as, and are directly applicable to, fairway woods and combinations thereof in sets of golf clubs. As illustrated by FIG. 1, golf club 10 is an elongate implement configured for striking a golf ball. Golf club 10 comprises a golf shaft 12 having a butt end 13 with a grip 14 and a tip end 15 coupled to a golf club head 16.
The shaft 12 is an elongate hollow tube extending along a first longitudinal axis. The shaft 12 tapers toward the tip end 15. The shaft 12 is formed of a lightweight, strong, flexible material, preferably as a composite material. In alternative embodiments, the shaft 12 can be formed of other materials such as, other composite materials, steel, other alloys, wood, ceramic, thermoset polymers, thermoplastic polymers, and combinations thereof. The shaft can be formed as one single integral piece or as a multi-sectional golf shaft of two or more portions or sections.
As used herein, the term “composite material” refers to a plurality of fibers impregnated (or permeated throughout) with a resin. The fibers can be co-axially aligned in sheets or layers, braided or weaved in sheets or layers, and/or chopped and randomly dispersed in one or more layers. The composite material may be formed of a single layer or multiple layers comprising a matrix of fibers impregnated with resin. In particularly preferred embodiments, the number layers can range from 3 to 8. In multiple layer constructions, the fibers can be aligned in different directions with respect to the longitudinal axis 18, and/or in braids or weaves from layer to layer. The layers may be separated at least partially by one or more scrims or veils. When used, the scrim or veil will generally separate two adjacent layers and inhibit resin flow between layers during curing. Scrims or veils can also be used to reduce shear stress between layers of the composite material. The scrim or veils can be formed of glass, nylon or thermoplastic materials. In one particular embodiment, the scrim or veil can be used to enable sliding or independent movement between layers of the composite material. The fibers are formed of a high tensile strength material such as graphite. Alternatively, the fibers can be formed of other materials such as, for example, glass, carbon, boron, basalt, carrot, Kevlar®, Spectra®, poly-para-phenylene-2,6-benzobisoxazole (PBO), hemp and combinations thereof. In one set of preferred embodiments, the resin is preferably a thermosetting resin such as epoxy or polyester resins. In other sets of preferred embodiments, the resin can be a thermoplastic resin. The composite material is typically wrapped about a mandrel and/or a comparable structure, and cured under heat and/or pressure. While curing, the resin is configured to flow and fully disperse and impregnate the matrix of fibers.
FIGS. 2-8 illustrate golf club head 16 in more detail. As shown by FIGS. 2-8, golf club head 16 comprises body 20, sole plate 40 and removable weights 42. Body 20 comprises a hollow structure that is coupled to the shaft. For purposes of this disclosure, the term “coupled” shall mean the joining of two members directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two members or the two members and any additional intermediate members being integrally formed as a single unitary body with one another or with the two members or the two members and any additional intermediate member being attached to one another.
In one implementation, the body 20 of the club head 16 can be formed as a single unitary, integral body through a combination of casting and welding. In another implementation, the club head 16 can be formed through a combination of forging and welding. In other implementations, the components of the body 20 of the club head 16 can be formed through casting, forging, welding, molding or a combination thereof. The body 20 of the club head 16 comprises a generally vertical front striking plate or strike face 22, a sole 24, a crown 26 and a hosel portion 28. The striking plate 22 extends from a heel portion 30 to a toe portion 32 of the club head 10.
As shown by FIGS. 3-7, the sole 24 and the crown 26 rearwardly extend from lower and upper portions of the striking plate 22, respectively. The sole 24 generally curves upward to meet the generally downward curved crown 26. The portion of the sole 24 adjacent the crown 26 that connects the sole 24 to the crown 26 at perimeter locations other than at the striking plate 22 can be referred to as a side wall 34 or skirt.
As shown by FIG. 7, crown 26 of the body 20 includes a central recessed region 60 that provides for and/or forms a sightline for the club head. The recessed region 60 can extend across the central area of the crown 26 from near the strike face 22 rearwardly toward the rear end of the club head 20. The recessed region 60 can have a length (measured from the strike face 22 rearward) of at least one inch and a width of at least 0.5 inches. In another implementation, the recessed region 60 can have a length of at least 2 inches and a width of at least 0.75 inch. In another implementation, the recessed region 60 can have a width that is approximately the same as the width of a golf ball, 1.680 inches. The recessed region 60 can have a length of approximately 3 inches. In other implementations, the recessed region 60 can have other dimensions. The recessed region 60 can be formed with a color that is different from the color of the other portions of the crown 26. In one implementation, the color of the recessed region 60 can be lighter than the color of the remaining portions of the crown 26. In another implementation, the color of the recessed region 60 can be darker than the color of the remaining portions of the crown 26. In another implementation, the recessed region 60 can include two or more colors. In another implementation, the recessed region 60 can include a color transition from a first color to a second color (or more colors). In one implementation, the front portion of the recessed region 60 has a white color to match the color of a golf ball.
The recessed region 60 can further include a narrow sight marker 62 positioned at the strike face 22 portion of the recessed region 60 and extending rearward over a portion of the recessed region 60. The sight marker 62 is centered about the strike face 22 and forms a ball alignment marker or ball sight for the user. The sight marker 62 is formed of a color that contrasts the color of the recessed region 60 surrounding the sight marker 62.
As shown by FIG. 6, the hosel portion 28 is a generally cylindrical body that upwardly extends from the crown 26 at the heel portion 30 of the club head 16 to couple the club head 16 to the shaft 12. The hosel portion 28 defines an upper hosel opening 36 for receiving the tip end of the shaft 12. The body 20 of the club head 16 is made of a high tensile strength, durable material, preferably a stainless steel or titanium alloy. Alternatively, the body 20 of the club head 16 can be made of other materials, such as, for example, a composite material, aluminum, other steels, metals, alloys, wood, ceramics or combinations thereof.
FIGS. 8 and 9 are exploded perspective views of head 16 illustrating sole 24 of body 20 in more detail. FIG. 10 is a sectional view illustrating an inside portion of the body 20 that forms sole 24. As shown by FIGS. 8-10, the sole 24 of the body 20 is formed with a set of structural ribs, including a center rib 42 and angled ribs 43, that define, with the remaining portions of the sole 24, a set of openings 44, 45. Center rib 42 extends along the centerline of head 16, opposite to and parallel to sight line 62. Openings 44 extend on opposite sides of center rib 42. Openings 45 extend on opposite sides of angled ribs 43 as openings 44. Openings 45 extend upwardly along sides of sole 24. In the example illustrated, openings 44 and 45 on one side of center rib 42 mirror of the openings 44 and 45 on the other side of center rib 42, providing symmetrical weight distribution along the centerline (and sight line 62) of head 62. In other implementations, such ribbing and openings may have other configurations.
The openings 44, 45 and ribs 42 43 of the sole 24 enable the weight of the sole 24 of the body 20 to be reduced. The openings 44, 45 also allow for the interior of the body 20 to be seen and visible and for any debris, or any particles or flakes that may break free from other locations of the body 20, to be readily removed from the body 24 by simply turning the body 24 such that the openings 44, 45 are orientated downward and the debris or other particles can be easily removed by gravity. The open structure of the sole 24 also eliminates the need to add a layer, or sections, of tacky material that is commonly utilized within many conventional club heads. The tacky material is intended to retain any particles or flakes that may break free from the club head during use or over time. Such particles or flakes have been known to cause a rattle or other noise that can be negatively received by the user. The absence of the tacky material due to the presence of the openings 44, 45 further reduces the weight of the body 20. The sole 24 defines a sole surface area, which is the lower surface of the club head 16 as shown in FIG. 3. In one implementation, the total area of the sole surface area can be 21.21 in2. In one implementation, each of the openings 44 define an area of approximately 0.556 in2, the opening 45 closer to the toe of the club head 16 defines an area of approximately 1.406 in2, and the opening 45 closer to the heel of the club head 16 defines an area of approximately 1.0954 in2. Accordingly, the openings 44 and 45 have a collective area of approximately 3.6173 in2. In this implementation, the openings 44 and 45 extend over approximately 17.05 percent of the sole surface area. In other words, the collective area of openings 44, 45 extend over at least 17 percent of the sole 24. The collective area of the openings 45 extend over approximately 11.8 percent of the sole surface area of the sole 24. The collective area of the openings 44 extend over approximately 5.25 percent of the sole surface area of the sole 24. Accordingly, in one implementation, the collective area of the openings 45 extend over at least 11 percent of the sole surface area. Additionally, in one implementation, the collective area of the openings 44 extend over at least 5 percent of the sole surface area. In other implementations, the openings 44 and 45 can define other areas. In another implementation, the collective area of openings 44 and 45 extend over at least 15 percent of the sole surface area of the sole 24. In another implementation, the collective area of the openings 44 and 45 define at least 20 percent of the sole surface area. In other implementations, the collective area of openings 44 and 45 can be sized to extend over at least 30 percent, 40 percent or 50 percent of the sole surface area of the sole 24.
The sole 24 includes a set of three threaded bores 46, 48 and 50. The first threaded bore 46 is positioned toward the rear of the sole 24, and the second and third threaded bores 48 and 50 of the sole are positioned on the skirt or sidewall of the sole toward the heel and toe of the body 20, respectively.
FIGS. 8, 9, 11 and 12 illustrate removable sole plate 40 in more detail. The removable sole plate 40 extends over the openings 44 and 45 of the sole 24 of the body 20, and the three threaded bores 46, 48 and 50. In the example illustrated, sole plate 40 comprises a front edge 100, a neck portion 102, a central breast 104, wings 106 and a tail 108. Front edge 100 comprises the forward edge of plate 40 which extends proximate to strike face 22 when plate 40 is mounted to head 16. Neck portion 102 extends forwardly from breast 104 so as to extend along and form a part of front edge 100.
Breast 104 extends between neck portion 102 and tail 108. Breast 104 forms the flat lower surface, covering the flat bottom of sole 24 of head 16. Breast 104 extends across and covers the openings 44 between ribs 42 and 43.
Wings 106 laterally extend from breast 104 and form portions of front edge 100 on opposite side of neck portion 102. As best seen in FIGS. 11 and 12, wings 106 curve away from breast portion 106 in an upward direction so as to wrap about the sides or skirt of head 16 when sole plate 40 is mounted to head 16. As a result, wings 106 distribute a customizable weight of sole plate 40 not just along the bottom of head 16, but also along the sides of head 16, along a majority of strike face 22, from the heel to the toe of head 16. Because wings 106 wrap about the underside of sole 24, sole plate 40 is more than a simple plate appended to the bottom side of sole 24, wherein wings 106 provide enhanced weight distributional along the sides of body 20 and more reliably and stably secure sole plate 40 to body 20.
Tail 108 extends rearwardly from breast 104 and rearwardly from wings 106, in a direction away from neck 102 and strike plate 22. As shown by FIGS. 4 and 5, the example illustrated, tail 108 extends upwardly as it extends rearwardly, approaching the top or crown of head 16. As a result, wings 106 and tail 108 form a cup-shaped plate into which body 20 is received (or which is removably applied to the body 20). Tail 108 provides additional weight is generally centered along the centerline of head 16, parallel to or along sightlines 62 (described above).
Wings 106 and tail 108 form a generally T-shaped structure, wherein wings 106 extend parallel or at least substantially parallel to the front strike face 22, providing rigidity and further distributing weight along and close proximity to front strike 22. Wings 106 and tail 108 each include mounting apertures through which removable weights 42, also serving as fasteners, extend into engagement with the threaded bores 46, 48 and 50. Wings 106 each include side mounting apertures 110 while tail 108 includes tail mounting aperture 112. Side mounting apertures 110 extend through the upwardly curving portions of wings 106 for being aligned with threaded bores 48 and 50 along the skirt of club head 16 on opposite sides of the centerline of club head 16. Tail mounting aperture 112 extends through tail 106 proximate a rear of head 16. In the example illustrated, each of apertures 110, 112 comprise counter sinks 113 for receiving portions of weights 42.
As shown by FIGS. 10-13, each of apertures 110, 112 is bordered and surrounded by a tube 114 projecting from the inner surface of sole plate 40. Tubes 114 are received within corresponding countersink bores 116 formed in sole 24 above threaded bores 46, 48 and 50. Tubes 114 and countersinks 116 facilitate securement, alignment and retention of sole plate 40 relative to sole 24 independent of weights 42. In other implementations, tubes 114 and/or countersinks may be omitted.
As further shown by FIGS. 8 and 9, sole plate 40 is sized and shaped or configured so as to fit within a recess 11 formed in sole 24. Recess 120 has an upper ceiling formed by ribs 42 and perimeter surfaces extending about countersinks 116 and threaded bores 46, 48 and 50. In the example illustrated, recess 120 comprises a central breast receiving portion 124, a neck recess 126, wing recesses 128 and a tail recess 130. Central breast receiving portion 124 of recess 120 extends below openings 44. Wing recesses 128 extend below openings and contain bores 48, 50. Tail recess 130 contains bore 46.
In the example illustrated, portions of sole 24 not occupied by recess 120 are further provided with additional cavities or recesses, reducing the weight of head 16 and providing additional structural strength about recess 120. In the example illustrated, sole 24 additionally comprises front side recesses 160 and rear side recesses 132. Front side recesses 160 have ceilings and sidewalls projecting upward into sole 24. Front side recesses 160 are each located between respective wing recesses 128 and strike face 22 on opposite sides of head 16. Likewise, rear side recesses 132 have ceilings and sidewalls projecting upward from into sole 24. Rear side recesses 132 are each located between respective wing recesses 128 and the rear or tale of club head 16.
FIG. 15 illustrates sole plate 40 received within recess 120, prior to the insertion of weights 42. In the example illustrated, recess 120 has a depth corresponding to the thickness of sole plate 40 such that when sole plate 40 has been received within recess 120, the lower face of sole plate 40 is substantially flush with the lower surfaces of sole 24 that are not covered by sole plate 40 and that extend adjacent to recess 120 of sole plate 40. The interaction between the side edges of sole plate 40 in the sidewalls are internal edges of recess 120 further assist in retaining sole plate 40 in place.
As further shown by FIG. 14, in the example illustrated, recess 120 is itself recessed with respect to the front of sole 24. In particular, the sole 24 comprises a downwardly extending wall 140 extending along the front strike face 22 about a first upwardly extending recess 142 behind the downwardly extending wall. Recess 142 has a ceiling 144 in which recess 120 is recessed in a further upward direction, rejecting further into ceiling 144. In other implementations, the additional recess 142 and/or additional wall 140 may be omitted.
In one implementation, the club head 16 can be produced with a single removable sole plate 40. In another implementation, the club head 16 can be sold or configured with one or more extra or spare sole plates. The sole plates 40 can have different weights, different textures, different colors, different graphics, different indicia and combinations thereof. In another implementation, the club head 16 can be sold or configured as a set with three or more weights 52 and two or more removable sole plates 40 that provide the user with a large number of different options for customizing the weight, weight distribution and appearance of the club head. The present invention allows for a high degree of customization and adjustability of the club head.
The removable sole plate 40 can be formed of a composite material. In another implementation, the sole plate 40 can be formed of an alloy, such as a titanium alloy or an aluminum alloy. In other implementations, the removable sole plate can be formed of other alloys, other metals, a composite/metal hybrid, or combinations thereof. The body 20 of the club head 16 is made of a high tensile strength, durable material, preferably a stainless steel or titanium alloy. Alternatively, the body 20 of the club head 16 can be made of other materials, such as, for example, a composite material, aluminum, other steels, metals, alloys, wood, ceramics or combinations thereof.
FIGS. 15 and 16 illustrate removable weights 42 in more detail. The set of removable weights 42 comprises threaded fasteners that removably connect the removable sole plate 40 to the body 20 of the club head 16. The weights 42 are threadedly engaged with the bores 46, 48 and 50 to removeably connect or retain the sole plate 40 to the body 20. Each weight 42 is configured to be positioned within any of the three threaded bores 46, 48 and 50. The weights 42 can have a weight within the range of 1 gram to 20 grams. In one implementation, each weight 42 has a weight within the range of 2 to 12 grams. The club head 16 can include 3 weights and each weight can have the same weight. Alternatively, the set of 3 weights can include two weights of the same weight and the third weight of a different weight. In another implementation, each of the three weights can be different weights. In other implementations, the club head can be configured with one or more extra or spare weights that provide the user with greater flexibility in adjusting the overall weight of the club head, and the weight distribution or configuration of the club head. The weights 42 are formed of one or more alloys. In other implementations, the weights can be formed of a heavy metal, other alloys, and combinations thereof.
As further shown by FIGS. 15 and 16, each of removable weights 42 has larger head portion 180 and a smaller diameter threaded shaft portion 182. Head portion 180 is configured to be engaged by a tool to facilitate removal and insertion of each weight 42 with respect to sole plate 40 and sole 24. As shown by FIG. 3, each head portion 180 is received within the countersinks 113 with the bottoms of weights 42 being flush with sole plate 40. As further shown by FIG. 3, weights 42 positioned within bores 48 and 50 are located on the side or skirt of head 16 to provide additional weight along the side of head 16, vertically above the lower surface of head 16. In one implementation, when the club head is positioned along a ground plane or horizontal surface such as shown in FIGS. 1, 4 and 5, the head portion 180 of weights 42 positioned within the bores 48 and 50 are spaced apart by a ground plane or a horizontal surface by at least 0.5 inch. In other words, the entire head portion 180 is at least 0.5 in above a ground plane or horizontal surface when the club head 16 is positioned in an address position as shown in FIGS. 1, 4 and 5. In addition to providing enhanced weight distribution, the positioning of weights 42 along the sides of head 16 reduces the likelihood that such weights 42 will be brought into contact with the ground during a golf swing. As a result, the lateral or side positioning of such weights 42, wherein weights 42 extending along axes that are oblique or angle with respect to the horizontal and with respect to the bottom of head 16, reduces the likelihood that such weights 42 one go impact that may loosen sole plate 40 with respect to body 20 of head 16. As shown in FIG. 15, in one implementation the threaded shaft portion 182 of the weights 42 can have similar lengths and dimensions even though the weights may have different values (the amount of weight in grams may vary from one weight 42 to the next). As shown in FIG. 16, the similarly sized threaded shaft portion 182 can be maintained on weights 42 of different values by the location of a lower surface 184 of the weights 42. A heavier weight will have its lower surface substantially equal to the lower end of the shaft portion 182, while lighter weights will have the lower surface 184 further into the threaded shaft portion 182 thereby resulting in a lower weight due to less material being used in the weight. One advantage of the similarly sized shaft portion 182 is that it provides sufficient threads for engagement between the sole plate 40 and the sole 24 of the body 20. In other embodiments, the weights 42 can be varied by other means, such as by varying the density of the material or materials used to produce the weights or other means.
FIGS. 17-20 illustrate golf club 210, another example implementation of golf club 10. Golf club 210 is similar to golf club 10 described above except that golf club 10 comprises golf club head 216 in lieu of golf club head 16. Golf club head 216 is itself similar to golf club head 16 except that head 216 comprises removable sole plate 240 and removable weights 242, 243. The body 20 includes a central recessed region 260 that provides for and/or forms a sightline for the club head. The recessed region 260 can further include a narrow sight marker 262 positioned at the strike face portion of the recessed region 260 and extending rearward over a portion of the recessed region 260. Those remaining components of golf club 210 which correspond to components of golf club 10 are numbered similarly.
Sole plate 240 is similar to sole plate 40 described above except that sole plate 240 has a rounded or curved front edge 300, more closely matching the rounded or curved strike face 22 of head 216. Sole plate 240 comprises mounting apertures 310, 312 through which weights 242, 243 extend into engagement with corresponding threaded bores 46, 48 and 50 in body 20 of head 216. The club head 216 further includes a groove 250 defined by the forward portion of the sole 224 and a forward region 252 of the sole plate 240. The groove 250 extends from the heel to the toe of the club head 216, and can follow or correspond to the curvature of the face or strike plate 22 of the club head 216.
Weights 242, 243 are similar to weights 42 described above in that weights 242, 243 are each configured to extend through sole plate 240 while being threaded into their corresponding threaded bores in body 20 of head 216.
