Aspects of this invention relate generally to golf clubs and golf club heads, and, in particular, to golf clubs and golf club heads having a portion of the club head removed or open, thereby creating a void in the club head, in order to reduce or redistribute weight associated with the club head to enhance performance.
Golf is enjoyed by a wide variety of players, players of different genders and players of dramatically different ages and/or skill levels. Golf club designers have successfully advanced the technology incorporated in golf clubs in response to the constant demand of golfers for improved performance. In one aspect, golfers tend to be sensitive to the “feel” of a golf club. The “feel” of a golf club comprises the combination of various component parts of the club and various features associated with the club that produce the sensations experienced by the player when a ball is swung at and/or struck. Club weight, weight distribution, swing weight, aerodynamics, swing speed, and the like all may affect the “feel” of the club as it swings and strikes a ball. “Feel” also has been found to be related to the sound produced when a club head strikes a ball to send the ball in motion. If a club head makes an unpleasant, undesirable, or surprising sound at impact, a user may flinch, give up on his/her swing, decelerate the swing, lose his/her grip, and/or not completely follow-through on the swing, thereby affecting distance, direction, and/or other performance aspects of the swing and the resulting ball motion. User anticipation of this unpleasant, undesirable, or surprising sound can affect a swing even before the ball is hit.
Also, the performance of a golf club can vary based on several factors, including weight distribution about the club head, which affects the location of the center of gravity of the golf club head. When the center of gravity is positioned behind the point of engagement on the contact surface, the golf ball follows a generally straight route. When the center of gravity is spaced to a side of the point of engagement, however, the golf ball may fly in an unintended direction and/or may follow a route that curves left or right, including ball flights that often are referred to as “pulls,” “pushes,” “draws,” “fades,” “hooks,” or “slices.” Similarly, when the center of gravity is spaced above or below the point of engagement, the flight of the golf ball may exhibit more boring or climbing trajectories, respectively.
Weight distribution about the club head can also affect moment of inertia associated with the club head. Thus, altering the moment of inertia can affect how the golf club performs including how the golf club head design impacts heel and toe mishits. Similarly, other factors such as point of impact and launch angle can also affect how the ball travels once it has been struck.
Club designers are often looking for new ways to distribute or redistribute weight associated with a golf club and/or golf club head. For instance, club designers are often looking to distribute weight to provide more forgiveness in a club head, improved accuracy, a desired ball spin and ball flight and the like. Club designers also seek to optimize the center of gravity location of the club head. In pursuit of such designs, club designers also face a challenge of maintaining a club head having a traditional aesthetic look desired by most golfers. Club designers further face the challenge of providing a club head having desirable sound characteristics upon ball impact. While certain golf club and golf club head designs according to the prior art provide a number of advantageous features, they nevertheless have certain limitations. Accordingly, it would be advantageous to provide a golf club and golf club head having a reduced weight characteristic and improved weight distribution throughout the club head to enhance club performance. The present invention is provided to overcome certain of the limitations and drawbacks of the prior art, and to provide new features not heretofore available.
At least some aspects of the disclosure relate to golf clubs and golf club heads having enhanced weight distribution about the club head. In one aspect, the golf club utilizes a geometric weight feature in the form of a void formed in the golf club head. The golf club head may include a cover extending over the void such that the void may not be visible from a top of the golf club head at an address position. In some examples, the golf club head may include certain support structures that enhance performance characteristics of the golf club head. In some additional examples, the golf club head may further include one or more adjustable weight arrangements.
According to another aspect of the invention, the golf club head is structured to maintain high moment of inertia properties and an enhanced center of gravity location. The structure of the golf club head further provides more pleasing acoustic characteristics.
According to another aspect of the invention, the golf club head has a body defining a ball striking face, a crown and a sole. The body further has a first leg extending away from the ball striking face and a second leg extending away from the ball striking face wherein a void is defined between the first leg and the second leg. The crown extends over the void. The void defines a first perimeter proximate an underside surface of the crown and the void defines a second perimeter proximate the sole, wherein the second perimeter is different from the first perimeter. In an exemplary embodiment, the second perimeter is greater than the first perimeter.
According to a further aspect of the invention, the golf club head has a body defining a ball striking face, a crown and a sole. The body further has a first leg extending away from the ball striking face and a second leg extending away from the ball striking face wherein a void is defined between the first leg and the second leg. The crown extends over the void. The body further defines an internal cavity. The first leg has a first wall extending between the crown and the sole, the first wall having a first inner surface facing into the internal cavity and a first outer surface facing into the void. The second leg has a second wall extending between the crown and the sole, the second wall having a second inner surface facing into the internal cavity and a second outer surface facing into the void.
According to a further aspect of the invention, the golf club head has a body defining a ball striking face, a crown and a sole. The body further has a first leg extending away from the ball striking face and a second leg extending away from the ball striking face wherein a void is defined between the first leg and the second leg. The crown extends over the void. The body further defines a bore receiving an adjustment member capable of adjusting a parameter of the golf club head. The sole defines a pathway surface positioned generally adjacent the bore, the pathway surface being void of interruption.

Several embodiments of golf club heads are disclosed herein. It is understood that the description of the club head and various components described above regarding
As shown in
As shown in
The club head 200 utilizes the geometric weighting feature and in an exemplary embodiment, a void 226, or space or gap, is defined between the first leg 222 and the second leg 224. Thus, it may be considered that this portion of the golf club head 200 is removed to form or define the void 226. In a further exemplary embodiment the void 226 is generally v-shaped. Thus, the first leg 222 and second leg 224 converge towards one another and generally meet at an interface area 228. The void 226 has a wider dimension at the rear 210 of the club head 200 and a more narrow dimension proximate a central region of the club head 200 generally at the interface area 228. The void 226 opens to the rear 210 of the club head 200. In one exemplary embodiment, the interface area 228 has a height H and is positioned proximate a central portion or region of the body 202 and defines a base support wall 230. The base support wall 230 may have a rounded surface that faces into the void 226. As explained in greater detail below, the first leg 222 defines a first wall 222a, and the second leg 224 defines a second wall 224b. A proximal end of the first wall 222a connects to one end of the base support wall 230, and a proximal end of the second wall 224b connects to another end of the base support wall 230. It is understood from the figures that the base support wall 230 can extend between the sole surface and the underside of the cover 204 in a general vertical configuration. In an exemplary embodiment, the base support wall 230 extends from the sole surface at an angle from a vertical axis. Thus, the base support wall 230 could extend along its length towards the rear 210 of the club head or towards the ball striking face 208. The base support wall 230 may meet a sole surface of the golf club head 200 to define a ridge location. It is understood that the legs 222, 224 and walls 222a, 224b can vary in length and can also be different lengths. External surfaces of the walls 222a, 224b face into the void 226 and may be considered to form a portion of an exterior of the golf club head 200.
An angle A is defined between the legs 222, 224 which angle can vary in degree, including a right angle, acute angles or obtuse angles. In one exemplary embodiment, the angle A can be in the general range of 30 degrees to 110 degrees, and more specifically 45 degrees to 90 degrees. It is further understood that the angle A can change from a location proximate the sole 214 to a location proximate an underside of the cover or crown 212. Accordingly, a shown in
With such structures, it is understood that the internal cavity 219 does not extend completely from an inner surface of the ball striking face 208 to a rear 210 of the golf club head 200. Thus, the internal cavity 219 is interrupted proximate the central region of the club head 200. It is further understood that the geometric weighting feature described herein is generally v-shaped wherein a width of the geometric weighting feature proximate the rear 210 is greater than a width of the geometric weighting feature towards the ball striking face 208.
As further shown in
As further shown in
In one exemplary embodiment, the side surfaces 232, 234 each have a plurality of ribs 240 or ridges extending from the proximal ends 236 towards the distal ends 238. Thus, the side surfaces 232, 234 have a stepped configuration or undulations. Such structures assist in adding a certain amount of rigidity to the body 202. It is understood that a single rib 240 could be used and only a single leg 222, 224 could have a rib 240. The rib 240 could further vary in length along the legs 222, 224 as well as be configured at an angle along the legs 222, 224 or also have a more vertical configuration. Other rigidity-enforcing structures could also be employed on the legs 222, 224 or other portions of the golf club head 200. It is further understood that in exemplary embodiments, the first leg 222 is generally defined by the first side surface 232 and the club head body 202 forming the heel 216 of the club head 200, and the second leg 224 is generally defined by the second side surface 224 and the club head body 202 forming the toe 218 of the club head 200. As can be appreciated from the figures, the sole 214 of the club head body 202 may be defined as adjacent the ball striking face 208, towards the central region of the club head 200 at the interface area 228 and to the distal ends of the first leg 222 and the second leg 224.
As can be further appreciated from
The club head body 202 defines additional internal support structures in the internal cavity 219 to enhance features of the club head 200. The structures may be internal support members, gussets, or fins, positioned in the internal cavity 219 to provide additional support to components of the club head 200. Accordingly, as shown in
As further shown in
The first gusset member 250 and the second gusset member 252 assist in adding stiffness, rigidity and load strength at the interface area 228 and limits flexing as desired to provide the desired performance characteristics including acoustic properties. Increased durability is also achieved. The gusset members 250, 252 do not add significant additional weight to the golf club head 200. With such constructions, weight distribution can be further maximized to be moved towards the rear at the heel 216 and the toe 218. The configuration of the void 226 can then also be maximized. These constructions further adjust sound characteristics of the golf club head 200 upon ball impact to desired frequency levels. It is noted that the sole surface is generally solid at locations where the gusset members engage and extend along the inner surface of the sole 214. Thus, no other weight port structures are positioned at the gusset members in an exemplary embodiment.
It is understood that additional gusset members could be utilized if desired or gusset members having different configurations than shown could also be utilized. For example, multiple gusset support members could span around different locations at the interface area or inner surfaces of the first leg and second leg. The gusset members 250, 252 could also be connected at the internal surfaces 232a, 234b of the legs rather than at the interface junctions 254, 256. The gusset members 250, 252 could also extend to and be connected to other internal surfaces of the club head. In addition, the gusset members 250, 252 could be dimensioned to extend across the interface face area 228 and against the internal surfaces 232a, 234b of the legs 222, 224 towards the rear of the golf club head 200. The gusset members 250, 252 are metallic members in one exemplary embodiment but other materials are possible including composite materials. It is further understood that the gusset support members could be cast or otherwise integrally formed with the club head body in the same forming process. The gusset support members can also be formed separately and later connected as described above such as by welding, adhesives or other connection techniques. While the gusset members are shown as triangular members in one exemplary embodiment, the gusset members could take many different shapes and sizes. The gusset members could further have certain cut-out portions or contours as desired.

The second transition surface 294 is radiused between the second wall 224 and a sole surface 224c of the second leg 222, thus providing a smooth transition between the more vertical second wall 224b and the more horizontal sole surface 224c, which is generally transverse to the second wall 224a. Similar to the first transition surface 292, the second transition surface 294 has a central segment 304 having a proximal segment 306 extending therefrom and further having a distal segment 308 extending from the central segment 304 opposite the proximal segment 306. The central segment 304 is positioned proximate the interface area 228 and generally possesses a maximum width of the second transition surface 294. The proximal segment 306 extends towards the ball striking face 208 and tapers from the central segment 304 towards the ball striking face 208. While the proximal segment 306 tapers to a point, the proximal segment 306 is generally transverse to the ball striking face 208. As further shown, the proximal segment 306 is made up of multiple segments. The distal segment 308 generally extends along the second wall 224b and also tapers from the central segment 304 towards the rear 210 of the golf club head 200. The distal segment 308 extends generally towards a rear toe area of the golf club head 200. The second transition surface 294 defines a generally linear baseline 310 extending between the proximal segment 306 and the distal segment 308.
The first transition surface 292 and the second transition surface 294 generally provide junction areas between the more vertically-oriented walls 222a, 224b and the sole surfaces 222c, 224c. The transition surfaces 292, 294 may generally comprise a convex, or outwardly radiused or contoured surface. The radius, or contour, may vary along the generally curved extent of the surfaces, and may or may not be a constant radius at any single location. It is further understood that the transition surfaces may generally comprise a concave, or inwardly radiused or contoured surface. The radius, or contour, may vary along the generally curved extent of the surfaces, and may or may not be a constant radius at any single location. It is also understood that the surfaces 292, 294 could have a beveled configuration. The transition surfaces 292, 294 could also be a more angled planar surface between the walls and sole surfaces if desired, or have more of a corner type configuration. Combinations of such configurations are also possible. The transition area 290 and surfaces 292, 294 lessen the surface intersections and can provide a more rounded or contoured configuration. These areas further assist in tying the crown 212 to the sole 214. The first transition surface 292 and the second transition surface 294 generally have equal lengths and extend along a majority of the surface of the sole 214 in one exemplary embodiment. It is understood that such length could vary, and the respective lengths of the transition surfaces 292, 294 could be different if desired. The transition surfaces 292, 294 further aid in achieving desired acoustic characteristics of the golf club head.
The uninterrupted area 320 generally includes a base area 322 and a first segment 324 extending from the base area 322 and a second segment 326 extending from the base area 322. In one exemplary embodiment, the first segment 324 is spaced from the second segment 326. In particular, the first segment 324 is spaced from the second segment 326 by the first transition surface 292. The base area 322 is generally positioned adjacent the ball striking surface 208 and generally midway between the heel 216 and toe 218. The base area 322 defines a substantially smooth surface and does not have surface interruptions including no indicia markings. The first segment 324 extends from the base area 322 at an angle along the first leg 222. In the exemplary embodiment, the first segment 322 is positioned between the first recessed surface 260 having the bore 264 and the first transition surface 292. The first segment 324 can extend at various lengths along the first leg 222. The first segment 324 has a generally longitudinal axis L that extends at an angle with respect to a plane PL generally defined by the ball striking surface 208 and shown schematically in
The cover 204 will cover the void 226 as well as the first leg 222 and second leg 224. The first leg 222 and the second leg 224 may be considered to depend from the cover 204. With such construction, and as shown generally schematically in
As further shown in
It is understood that the structures of the golf club head 200 described herein cooperate to form a club head having enhanced characteristics. The void construction provides the ability to distribute weight more towards the rear at the heel and toe. In further exemplary embodiments, the club head 200 could be structured wherein wall thicknesses of the first leg and second leg can be increased in the manufacturing process to further increase weight towards the rear at the toe and the heel. Wall thicknesses at the distal ends of the legs can be increased to add weight at the rear at the toe and heel. It is further understood that weight members can be internally supported in the legs. Additional structures such as the gusset members provide for the desired amount of rigidity and flexing. The resulting club head provides enhanced performance and sound characteristics.
It is understood that the embodiments described herein regarding
As discussed, the geometric weighting feature of the golf club heads described herein provides structure that allows for enhanced performance characteristics, including moment of inertia (MOI) properties, center of gravity (CG) properties and acoustic properties.
As discussed, the geometric weighting feature provides for weight to be moved from generally a rear of the sole of the club head to more towards the rear heel of the club head and the rear toe of the club head. In one exemplary embodiment of the invention, approximately 5% of the golf club head mass is moved in this fashion. Such construction provides a high moment of inertia (MOI) about a vertical axis (z-axis) through the center of gravity (CG) of the club head (Izz). Maintaining the higher MOI increases ball speed on off-center ball impacts and decreases the effect of side spin caused by off-center impact.
The geometric weighting feature also allows for enhanced positioning of the CG. The structure further allows for enhanced positioning of the CG such that a desired ball spin is imparted to the ball during impact with the club head 102. In certain exemplary embodiments, the CG is positioned such that a reduced amount of spin is imparted to the ball during impact. In the exemplary embodiments described herein, the CG is located within the internal cavity 219 of the golf club head 200. To achieve such properties, the CG is moved forward wherein the perpendicular distance from the CG to the ball striking face of the head is minimized. The structure of the club head wherein the weight is moved from the rear of the sole to the rear heal and rear toe areas allows for movement of the CG closer to the ball striking face. It has been found that when the perpendicular distance from the ball striking face to the CG is greater (such as when weight is moved to the rear of the golf club head to increase MOI), a wider variation of both ball back spin and ball side spin is produced for impact locations across the ball striking face. The structure of the geometric weighting features provides for an optimal balance of the MOI and CG properties, wherein more efficient control of ball back spin and ball side spin is achieved. As a result, ball carry distance is improved with the golf club head 200.
The geometric weighting feature further provides enhance acoustic properties of the golf club head. The structure provides for a more stiffened construction that promotes a higher natural frequency and a more pleasing sound. In many traditional golf club head designs, the crown of the head is only supported at peripheral edges, which can lead to relatively low natural frequencies and more unpleasant sounds are radiated to the golfer upon ball impact.
As discussed with the present golf club head 200 as well as the other embodiments described herein, the legs have walls that define the void and integrally depend from the crown and attach to the sole in an exemplary embodiment of the invention. Accordingly, in addition to being supported at peripheral edges, the crown is also supported at locations inwardly spaced from the peripheral edges. The walls extend along a considerable distance along the crown, or considerable footprint. The thickness of the walls may be approximately 7 mm similar to other structures of the club head body 202 wherein the thickness could vary approximately +1-10%. Such construction provides enhanced sound characteristics as the first flexural frequency of the club head is increased. Due to the increased stiffness provided by the construction of the walls connecting the crown and sole, a smaller portion of the crown emits any significant amplitude upon ball impact. With a higher frequency of the crown mode, and a smaller amount of the crown emitting amplitude, the amount of sound created by the club head is reduced when compared to conventional golf club head designs. The sound created is less intense and at a higher pitch than that of conventional golf club designs. Thus, the walls can be considered as sound reducing structures. The walls depend from the crown and connect to the sole. While inner surfaces of the walls confront the internal cavity 219, outer surfaces of the walls face the exterior of the golf club head. The outer or external surfaces of the walls face into the void and may be considered to form a portion of the exterior of the golf club head. The walls may further be considered to be located within the outermost periphery defined by the golf club head.
It is further understood that the walls have a major length extending from an end proximate the interface area 228 to a point where the distal ends angle inward to the rear of the club head 200. As can be appreciated from
It is noted that certain exemplary embodiments of golf club heads according to the present invention are listed in Table 1 as well as additional Tables listing other various data discussed below. The embodiments include: a Driver #1; a Driver #2, a Fairway Wood—3W; a Fairway Wood—5W; and a Hybrid. The Driver #1 may be a contemporary tour type driver for an advanced player, and having a volume of approximately 400-430 cm3. The Driver #1 golf club head has the following characteristics: a breadth of approximately 106.6 mm; a length of approximately 114.7 mm; a head height of approximately 65.7 mm; and a face height of approximately 60.5 mm. It is understood that these characteristics are determined based on the USGA Procedure for Measuring the Club Head Size of Wood Clubs, USGA-TPX 3003. The Driver #2 may be a contemporary game improvement type golf club, and having a volume of approximately 430-460 cm3. The Driver #2 golf club head has the following characteristics: a breadth of approximately 114.5 mm; a length of approximately 119.8 mm; a head height of approximately 62.1 mm; and a face height of approximately 59.3 mm. The Fairway Wood—3W may have a volume of approximately 180-190 cm3. The Fairway Wood—3W golf club head has the following characteristics: a breadth of approximately 87.8 mm; a length of approximately 101.5 mm; a head height of approximately 42.2 mm; and a face height of approximately 37.7 mm. The Fairway Wood—5W may have a volume of approximately 170-175 cm3. The Fairway Wood—5W golf club head has the following characteristics: a breadth of approximately 84.9 mm; a length of approximately 99.7 mm; a head height of approximately 39.3 mm; and a face height of 35.3 mm.

The Hybrid golf club head has the following characteristics: a breadth of approximately 62.3 mm; a length of approximately 101.2 mm; a head height of approximately 39 mm; and a face height of 37.8 mm.
The lengths L1-L4 of the walls 222a, 224b provide a significant length of connection between the crown 212 and the sole 214. The lengths L2, L4 along an underside surface of the crown 212 further provide a significant length of structure integral with and depending from the crown 212. Such construction provides enhanced and desired acoustic properties. The length L5 representing a maximum distance between the legs in the void can also vary to achieve desired performance characteristics, and be dimensioned with respect to other parameters.
Table 2 below lists example void perimeter data for different types of golf club heads according to exemplary embodiments of the invention:
As the walls taper outwardly and diverge from an underside surface of the crown to the sole, the first void perimeter P1 is generally smaller than the second void perimeter P2. In exemplary embodiments, the first void perimeter P1 may be within a certain percentage range of the second void perimeter P2. For the Driver #1 golf club head, the first void perimeter may be approximately 80-90% of the second void perimeter and in one particular exemplary embodiment, the first void perimeter is 85.6% of the second void perimeter. For the Driver #2 golf club head, the first void perimeter may also be approximately 80-90% of the second void perimeter and in one particular exemplary embodiment, the first void perimeter is 85.6% of the second void perimeter. For the Fairway Wood—3W golf club head, the first void perimeter may be approximately 75-85% of the second void perimeter and in one particular exemplary embodiment, the first void perimeter is 80.9% of the second void perimeter. For the Fairway Wood—5W golf club head, the first void perimeter may also be approximately 75-85% of the second void perimeter and in one particular exemplary embodiment, the first void perimeter is 78.6% of the second void perimeter. For the Hybrid golf club head, the first void perimeter may be approximately 80-90% of the second void perimeter and in one particular exemplary embodiment, the first void perimeter is 87.2% of the second void perimeter. It is further understood that for the various golf club heads according to the present invention, the first void perimeter may be approximately 70-90% of the second void perimeter. With the outwardly tapered walls discussed above, the first void perimeter P1 can be minimized thus also reducing the crown area defined by the first void perimeter P1. This provides for a high modal frequency and a reduced amplitude upon ball impact in this area. The perimeter dimensions also result in less sole area. Controlling the dimensions of the perimeters provides for structural efficiency, and the benefits of the void and stiffening walls are maintained. Thus, the overall characteristics of the void construction is balanced to achieve the desired performance characteristics. It is understood that in other embodiments, the golf club head can be constructed such that the first void perimeter P1 is larger than the second void perimeter P2.
As discussed, the structures of the golf club head 200 define the internal cavity 219 and the void 226. It is understood that the golf club head 200 and other golf club head embodiments described herein have a volume associated therewith. The club head volume may be determined using the United States Golf Association and R&A Rules Limited Procedure For Measuring the Clubhead Size of Wood Clubs. In such procedure, the volume of the club head is determined using the displaced water weight method. It is further understood that according to the procedure the void structure and other concavities may be filled with clay or dough and covered with tape so as to produce a smooth contour over the sole of the club head. Club head volume may also be calculated from three-dimensional modeling of the golf club head if desired. It is further understood that the internal cavity 219 has a volume V1. It is further understood that the void 226 may define a volume V2. The volume of the void 226 is partially defined by the underside surface of the cover and the walls 222a, 224b. An imaginary continuation of the first wall and second wall as well as the arc of the crown upwards defines the outer boundary of the void 226, wherein such imaginary continuations produce a smooth contour over the sole. The volume V2 of the void 226 may be dimensioned to be a certain percentage of the volume V1 of the internal cavity 219. As discussed, the location of the interface area 228 can vary as well as the angle between the legs 222, 224. Such variations can affect the respective volumes V1, V2 of the internal cavity 219 and void 226, which will further affect the performance characteristics of the golf club head 200 as desired.
Table 3 below lists example volume data for different types of golf club heads according to exemplary embodiments of the invention:
It is understood that the volume V2 of the void 226 may be within a certain percentage range of the volume V1 of the internal cavity 219. For the Driver #1 golf club head, the void volume may be 20-25% of the internal cavity volume, and in one exemplary embodiment the void volume is 21.6% of the internal cavity volume. For the Driver #2 golf club head, the void volume may be 15-20% of the internal cavity volume, and in one exemplary embodiment the void volume is 16.7% of the internal cavity volume. For the Fairway Wood—3W golf club head, the void volume may be 15-20% of the internal cavity volume, and in one exemplary embodiment the void volume is 19.4% of the internal cavity volume. For the Fairway Wood—5W golf club head, the void volume may be 15-20% of the internal cavity volume, and in one exemplary embodiment the void volume is 18.8% of the internal cavity volume. For the Hybrid golf club head, the void volume may be 15-20% of the internal cavity volume, and in one exemplary embodiment the void volume is 17.1% of the internal cavity volume. It is further understood that for the various golf club heads according to the present invention, the void volume may be 15-25% of the internal cavity volume or even 15-20% of the internal cavity volume in further embodiments. The respective volumes are dimensioned to achieve the desired performance characteristics of the golf club.
As previously indicated, the legs 222, 224 and walls 222a, 224b extend from one another at an angle. The walls 222a, 224 taper outwardly from an underside surface of the crown to the sole. As such and as shown in
Table 1 contains data regarding representative lengths regarding the walls as well as maximum cavity distance, while Table 4 contains data regarding the angles between the walls. It is understood that the lengths and angles can be dimensioned in various relationships to achieve desired performance characteristics.
As discussed, the crown of the golf club head generally covers the legs and void in exemplary embodiments of the invention. The crown, or cover, has a segment 272 (shown schematically in
Thus, the surface area of the segment of the crown confronting the void may be a certain percentage of the overall surface area of the crown. For the Driver #1 golf club head, the surface area of the crown over the void may be 10-20% of the overall surface area of the crown, and in one exemplary embodiment the surface area of the crown over the void is 15.2% of the overall surface area of the crown. For the Driver #2 golf club head, the surface area of the crown over the void may also be 10-20% of the overall surface area of the crown, and in one exemplary embodiment the surface area of the crown over the void is 13.3% of the overall surface area of the crown. For the Fairway Wood—3W and 5W golf club heads, the surface area of the crown over the void may be 10-20% of the overall surface area of the crown, and in one exemplary embodiment the surface area of the crown over the void is 14.2% of the overall surface area of the crown. For the Hybrid golf club head, the surface area of the crown over the void may be 10-20% of the overall surface area of the crown, and in one exemplary embodiment the surface area of the crown over the void is 16.4% of the overall surface area of the crown. It is further understood that for the various golf club heads according to the present invention, the surface area of the crown over the void may be 10-25% of the overall surface area of the crown or even 10-20% of the overall surface area of the crown.
While specific dimensions, characteristics, and/or ranges of dimensions and characteristics are set forth in the various tables above and other paragraphs herein, those skilled in the art will recognize that these dimensions and ranges are examples of the invention. Many variations in the ranges and the specific dimensions and characteristics may be used without departing from this invention, e.g., depending on the type of club, user preferences, user swing characteristics, and the like. Such data may also vary due to other desired club parameters as well as shaft selection. In certain exemplary embodiments, the data described herein may vary in the range of +/−10%. It is further understood that from the data disclosed herein, further parameters, relationships, percentages etc. can readily be determined and recognized by a person skilled in the art. In addition, a golf club head structure need not have dimensions or characteristics that satisfy all of various data values described herein to fall within the scope of this invention.
The golf club head 400 utilizes a weight assembly to further enhance performance of the club head 400. The weight assembly or weight is operably associated with the interface area 428. In an exemplary embodiment, the interface area 428 of the head 400 supports a receptacle or receiver 442 in the form of a receiving tube 442 in an exemplary embodiment. A weight 440 of the weight assembly is configured to be received by the receiving tube 442.
The receiving tube 442 and weight 440 may have corresponding shapes such that the weight 440 may slide into the receiving tube 442. In some examples, the weight 440 and receiving tube 442 may be cylindrical, square, rectangular, etc. The receiving tube 442 may have a longitudinal axis and the weight may have a longitudinal axis. The longitudinal axes may generally correspond when the weight 440 is received in the tube 442. In the embodiment shown in
In the example shown in
The receiving tube 442 may receive the weight 440 which may be a single weighted member or may have ends with different weighting characteristics or weight values. For instance, the weight 440 may have one end 440a heavier than an opposite end 440b. In some arrangements, the heavier end may be positioned towards the top of the golf club head to provide a first weight arrangement or alternatively, towards the bottom of the golf club head to provide a second weight arrangement. The different weight arrangements can affect performance of the club head 400. The v-shaped void 426 may permit easier access to the body of the golf club head 400, weights 440, etc. to more easily adjust weight from a high position to a low position. Other structures can be operably associated with the interface area at the void 426 to removably support weight members thereon.
Additionally or alternatively, the weight member 440 may include multiple weights or portions of the weight 440 that can be releasably fastened to one another; e.g. three pieces with one piece being heaviest (e.g., shown in phantom lines in FIG. A). The different weights may also have different weight values. In some examples, the heavy member can be at either end or at a middle of the member. Various other combinations of weight members may be used without departing from the invention. The overall height of the weight member 440 along with the length of the threaded fastener 444 may generally correspond to the height of the receiver tube 442 so that the weight 440 fits snugly in the tube 442 and does not slide within the tube during use. It is understood that the tube 442 and/or the weight 440 may have shock absorbing features if desired.
In some arrangements, the base of the v-shaped void 426 may be angled and the receiving tube 442 may conform to the angle. Thus, the weight member 440 may be adjusted in a hybrid fashion, e.g., high/low, fore/aft, by adjusting the weight 440 within the receiving tube 442. Multiple receiving tubes 442 can also be utilized in vertical, horizontal or angular configurations. The receiving tube(s) may also be positioned at locations spaced away from the interface area 428 including along surfaces of the first leg 422 and the second leg 424.
The position of the weight 440 and receiving tube 442 at the base of the v-shaped void 426 may aid in adjusting the center of gravity near a central region of the golf club head 400. Weight in the tube 442 can be focused in the tube 442 to provide a low center of gravity or a high center of gravity. The weight 440 can also be configured to provide a more neutral center of gravity. The insertion or removal of weight 440 may add or remove additional weight from the overall weight of the golf club head 400 and may add or remove weight from the central region, thereby adjusting the performance characteristics of the golf club head 400. Such weighting characteristics provided by the weight 440 in the tube 442 can further impact golf ball trajectory by providing a change in ball spin. It has been determined that this weighting feature can provide a change of approximately 500-600 rpm in ball spin. Utilizing the adjustable weight 440 in the tube 442 to affect ball spin as well as considering launch angle and ball speed, a golfer can customize the golf club to achieve desired ball trajectory, distance and other characteristics. The adjustable weighting feature can further be used to customize the club head 400 to produce a desired ball spin for a particular golf ball being used.
The weight assembly utilized in
Similar to the arrangement discussed above regarding
Additionally or alternatively, the weight may be comprised of multiple weight portions having varying weight characteristics, as described above. For instance, portions 440a and 440b may be separate portions of the weight 440 that may be connected together in multiple configurations to adjust the weight distribution and thereby adjust the performance characteristics of the golf club head 400. Although two weight portions are shown in
In some examples, the receiving tube 442 may include a fastener 444 to secure the weight 440 within the receiving tube 442. For instance, a screw or other threaded fastener 444 may be inserted into the receiving tube 442 after the weight 440 has been inserted to maintain the position of the weight 440. The receiving tube 442 has mating threads to receive the threaded fastener 444. In order to remove or adjust the weight, the fastener 444 may be removed and the weight 440 may then be removed. Similar to the arrangements discussed above, access to the weight 440 and fastener 444 may be via the void 426 formed in the rear of the golf club head 400. It is understood that the weight 440 could be secured in the tube 440 in several other alternative embodiments.
Additionally or alternatively, the weight 440 may be threaded or connected to a threaded fastener 450 such that adjustment of the thread moves the weight 440 within the receiving tube 442. For instance, turning of the threaded fastener 450 may move the fastener 450 up or down within the receiving tube 442. A weight 440 connected to the fastener 450 may then also move up and down with the threaded fastener 450. As further shown in
Although the above-described arrangements including a receiving tube generally illustrate an exterior of the receiving tube being exposed, the receiving tube may be enclosed within a rear portion of the golf club head without departing from the invention. For example, the interface area of the golf club head may completely enclose the receiving tube or some other structure to receive a weight member.
It is further understood that an adjustment member 105 may be utilized in exemplary embodiments of the present invention. The adjustment member 105 is operably connected to the golf club head and capable of adjusting certain parameters of the golf club head, such as loft angle, face angle and/or lie angle. Other parameters could also be adjusted. It is understood that the adjustment member 105 could be utilized in any of the embodiments described herein.
The releasable connection 105, as described below, includes two different sleeves, the shaft adapter 500 and the hosel adapter 600. These two different sleeves provide the ability to adjust two different club head parameters independently. Additionally, in accordance with aspects of this invention, one sleeve may be utilized, wherein either the shaft adapter 500 or the hosel adapter 600 may be eliminated such that only one club head parameter may be adjusted independently of the other parameters or characteristics with substantially no change (or minimal change) in the other parameters or characteristics of the golf club head 200. In another embodiment, one of either the shaft adapter 500 or the hosel adapter 600 may include an off-axis or angled bore and the other of the shaft adapter 500 or the hosel adapter 600 may not include an off-axis or angled bore. Additionally, in accordance with aspects of this invention, the two different sleeves 500, 600 may be utilized with off-axis or angled bores, however they may provide the ability to adjust one club head parameter independently with substantially no change (or minimal change) in the other parameters or characteristics of the golf club head. With this embodiment, only one club head parameter may be adjusted independently of the other parameters or characteristics. For each of these adjustments, whether adjusting two different club head parameters independently or adjusting one club head parameter, there may be substantially no change (or minimal change) in the other parameters or characteristics of the golf club head.
In this exemplary embodiment, neither the shaft adapter 500 nor the hosel adapter 600 need to be removed from the club head 200 to rotate the shaft adapter 500 and/or the hosel adapter 600 to various configurations. The shaft adapter 500 and the hosel adapter 600 are captive within the releasable connection 105 (See e.g.,
As illustrated in
As shown, at least a portion of the first end 504 of the shaft adapter 500 includes a first rotation-inhibiting structure 512. While a variety of rotation-inhibiting structures may be provided without departing from this invention, in this example structure, the rotation-inhibiting structure 512 constitutes splines 512a extending along a portion of the longitudinal axis 526 of the exterior surface of the shaft adapter 500. The splines 512a of the shaft adapter 500 may prevent rotation of the shaft adapter 500 with respect to the member into which it is fit (e.g., a hosel adapter, as will be explained in more detail below). A variety of rotation-inhibiting structures may be used without departing from the invention. The interaction between these splines and the hosel adapter cylindrical interior will be discussed in more below. Other configurations of splines may be utilized without departing from this invention.
The first rotation-inhibiting structure 512 may extend along a length of the shaft adapter 500 such that the hosel adapter 600 can be disengaged from the first rotation-inhibiting structure 512 and be rotated while still captive on the shaft adapter 500.
Other features of this example shaft adapter 500 may include an “off-axis” or angled bore hole or interior chamber 508 in which the shaft 106 is received as illustrated for example in
While any desired shaft adapter offset angle may be maintained between the first axial direction and the second axial direction, in accordance with some examples of this invention, this shaft adapter offset angle or face angle adjustment may be between 0.25 degrees and 10 degrees, and in some examples between 0.5 degrees and 8 degrees, between 0.75 degrees and 6 degrees, or even between 1 degree and 4 degrees. In more specific examples of the invention, the shaft adapter offset angle or face angle adjustment may by approximately 1.5 degrees offset or 2.0 degrees offset.
As illustrated in
Other features of this example hosel adapter 600 may include an “off-axis” or angled bore hole or interior chamber 608 in which the shaft adapter 200 is received as illustrated for example in
While any desired hosel adapter offset angle may be maintained between the first axial direction and the second axial direction, in accordance with some examples of this invention, this hosel adapter offset angle or face angle adjustment may be between 0.25 degrees and 10 degrees, and in some examples between 0.5 degrees and 8 degrees, between 0.75 degrees and 6 degrees, or even between 1 degree and 4 degrees. In more specific examples of the invention, the hosel adapter offset angle or face angle adjustment may by approximately 1 degree or one-half degree offset.
The second end 606 of the hosel adapter 600 defines a second opening 610 for receiving a securing member 808. Generally, the second opening 610 is sized such that the securing member 808 is able to freely pass through the second opening 610 to engage the threaded hole 510 in the shaft adapter 500. Alternatively, if desired, the securing member 808 also may engage the hosel adapter 600 at the second opening 610 (e.g., the second opening 610 may include threads that engage threads provided on the securing member 808). The securing member 808 may also include a spherical washer 808A and a screw retention device 408B.
As illustrated in
As illustrated in
The hosel adapter 600 may also be non-rotatable with respect to the golf club head 200. As illustrated in
The hosel adapter 600 may be made from any desired materials and from any desired number of independent parts without departing from this invention. In this illustrated example, the entire hosel adapter 600 is made as a unitary, one-piece construction from conventional materials, such as metals or metal alloys, plastics, and the like. In at least some example structures according to this invention, the hosel adapter 600 will be made from a titanium, aluminum, magnesium, steel, or other metal or metal alloy material. Additionally, the hosel adapter 600 may be made from a self-reinforced polypropylene (SRP), for example PrimoSpire® SRP. The bore and/or surface structures (e.g., splines 612a, splines 622a, and expanded portion 618) may be produced in the material in any desired manner without departing from the invention, including via production methods that are commonly known and/or used in the art, such as by drilling, tapping, machining, lathing, extruding, grinding, casting, molding, etc. The shaft adapter 500 and hosel adapter 600 and any of the other parts could be metal or plastic, or any other suitable materials in any combination. For example, the hosel adapter 600 may be a high-strength plastic while the shaft adapter 500 is made of a metal. Other combinations may utilized without departing from the invention.
Exemplary hosel rings 700 are illustrated in
The hosel ring 700 may also be non-rotatable with respect to the golf club head 200. In an exemplary embodiment, the hosel ring 700 may secured to the club head chamber 264 by any means known and/or used in the art, such as adhesive, glue, epoxy, cement, welding, brazing, soldering, or other fusing techniques, etc.
The hosel ring 700 may be made from any desired materials and from any desired number of independent parts without departing from this invention. In this illustrated example, the entire hosel ring 700 is made as a unitary, one-piece construction from conventional materials, such as metals or metal alloys, plastics, and the like. In at least some example structures according to this invention, the hosel ring 700 will be made from a titanium, aluminum, magnesium, steel, or other metal or metal alloy material. The bore and/or surface structures (e.g., splines 712a) may be produced in the material in any desired manner without departing from the invention, including via production methods that are commonly known and/or used in the art, such as by drilling, tapping, machining, lathing, extruding, grinding, casting, molding, etc.
The adjustment of the rotational position of the shaft adapter 500 (and the attached shaft 106) and hosel adapter 600 will be explained in more detail below in conjunction with
To enable users to easily identify the “settings” of the golf club head 200 (e.g., the club head body 202 position and/or orientation with respect to the shaft 106), any or all of the shaft 106, the shaft adapter 500, hosel adapter 600, and/or the club head 200 may include markings or indicators or other indicia.
Golf club adjustability design has generally included having mating parts and cooperating engagement surfaces allowing for specific adjustability of the golf club head 200. However, these current designs offer many possible adjustable combinations regarding loft angles, face angles, and lie angles. While this adjustability provides some benefits to the golfers, a large number of options to the golfer can also be confusing and cumbersome to the golfer. In certain exemplary embodiments, the present design and specifically the spline configurations of the various rotation-inhibiting structures, provide a limited set of adjustability options that is more user-friendly for the golfer. For example, the adjustability may be limited to only three different adjustable loft angles and three different adjustable face angles. The loft angles may vary from 7.5 degrees to 12.5 degrees. The face angles may be generally referred to as Neutral, Open, and Closed. Therefore, each club head will have a finite number of rotatable positions, such as a total of nine different face angle and loft angle configurations. The configuration of the rotation-inhibiting structures limit the rotational positions of the shaft adapter 500 and the hosel adapter 600, providing more simple, streamlined adjustment features for the golfer. Thus from the figures and descriptions herein, the various spline configurations having engagement surfaces structured such that certain positions are allowed to provide desired adjustment while additional positions are prevented (e.g. the respective splines cannot fit together) to specifically limit the adjustability options. Thus, the respective spline configurations of the shaft adapter 500, hosel adapter 600 and hosel ring 700 define surfaces that prevent cooperative mating and engagement among the components.
Another exemplary option set is using four different adjustable loft angles and three different adjustable face angles, thereby creating a club head with a total of twelve different face angle and loft angle configurations. Another exemplary option set is using five different adjustable loft angles and three different adjustable face angles, thereby creating club head with a total of fifteen different face angle and loft angle configurations. Another exemplary option set is using seven different adjustable loft angles and three different adjustable face angles, thereby creating club head with a total of twenty-one different face angle and loft angle configurations. Other configurations of adjustable face angles and loft angles may be utilized without departing from this invention. It is understood that the respective spline configurations are modified to provide such different configurations discussed.
The exemplary embodiment in
It should be understood that a “Neutral” face angle may be a reference point/reference face angle and not an actual “neutral” face angle of the face or club head. For example, “Neutral” may represent a 1-degree closed face angle of the face. Using a 2-degree face angle adjustment, “Closed” would have a 3-degree closed face and “Open” would have a 1-degree open face. In another example, “Neutral” may represent a 3-degree open face angle of the face. Using a 2-degree face angle adjustment, “Closed” would have a 1-degree open face and “Open” would have a 5-degree open face.
The spline configuration of the embodiment illustrated in
Accordingly, the adjustment member 105 allows adjustment of parameters such as loft angle and face angle in exemplary embodiments of the invention. Such club head parameter adjustment affects the overall position of the golf club head, for example, with respect to the golf club shaft 106.
Several different embodiments of the golf club head of the present invention have been described herein. The various embodiments have several different features and structures providing benefits and enhanced performance characteristics. It is understood that any of the various features and structures may be combined to form a particular club head of the present invention. It is further understood that the various types of golf club heads disclosed herein could be grouped together based on certain parameters and provided as a kit or set of clubs.
The structures of the golf club heads disclosed herein provide several benefits. The unique geometry of the golf club head provides for beneficial changes in mass properties of the golf club head. The geometric weighting feature provides for reduced weight and/or improved weight redistribution. The void defined in the club head can reduce overall weight as material is removed from a conventional golf club head wherein a void is defined in place of such material that would normally be present. The void also aids in distributing weight throughout the club head to order to provide improved performance characteristics. The void provides for distributing weight to the rear corners of the club head, at the toe and the heel. Increases in moment of inertia have been achieved while optimizing the location of the center of gravity of the club head. This can provide a more forgiving golf club head as well as a golf club head that can provide more easily lofted golf shots. In certain exemplary embodiments, the weight associated with the portion of the golf club head removed to form the void may be approximately 4-15 grams and more particularly, 8-9 grams. In other exemplary embodiments, this weight savings may be redistributed to other areas of the club head such as towards the rear at the toe and the heel. In certain exemplary embodiments, approximately 2% to 7.5% of the weight is redistributed from a more traditional golf club head design. In still further examples, the void may be considered to have a volume defined by an imaginary plane extending from the sole surfaces and rear of the club and to cooperate with the side surfaces of the legs and underside portion of the cover. The internal cavity may also have a certain volume. The volumes are dimensioned to influence desired performance characteristics. It is further understood that certain portions of the club head can be formed from alternative materials to provide for weight savings or other weight redistribution. In one exemplary embodiment, the walls defining the void may be made from other materials such as composites or polymer based materials.
As discussed, the weight can be redistributed to more desired locations of the club head for enhanced performance. For example, with the centrally-located void and the legs extending outwardly towards the rear on the heel side and the toe side, more weight is located at such areas. This provides more desired moment of inertia properties. In the designs described herein, the moment of inertia (MOI) about a vertical axis (z-axis) through the center of gravity of the club head (Izz) can range from approximately 1500 gm-cm2 to 5900 gm-cm2 depending on the type of golf club. In an exemplary embodiment for a driver type golf club, the moment of inertia about a vertical axis (z-axis) through the center of gravity of the club head (Izz) can range from approximately 3800 gm-cm2 to 5900 gm-cm2, and in a further exemplary embodiment, the Izz moment of inertia can range from 4300 gm-cm2 to 5200 gm-cm2. In an exemplary embodiment of a fairway wood type golf club, the moment of inertia about a vertical axis (z-axis) through the center of gravity of the club head (Izz) can range from approximately 2000 gm-cm2 to 3500 gm-cm2, and in a further exemplary embodiment, the Izz moment of inertia can range from 2200 gm-cm2 to 3000 gm-cm2. In an exemplary embodiment of a hybrid type golf club, the moment of inertia about a vertical axis (z-axis) through the center of gravity of the club head (Izz) can range from approximately 2000 gm-cm2 to 3500 gm-cm2, and in a further exemplary embodiment, the Izz moment of inertia can range from 2200 gm-cm2 to 3000 gm-cm2, and in a further exemplary embodiment, the Izz moment of inertial can range from 1800 gm-cm2 to 2800 gm-cm2. In a particular embodiment utilizing the adjustable connection mechanism in the hosel, the Izz moment of inertia is approximately 4400 gm-cm2 to 4700 gm-cm2. These values can vary. With such moment of inertia properties, improved ball distance can be achieved on center hits. Also, with such moment of inertia properties, the club head has more resistance to twisting on off-center hits wherein less distance is lost and tighter ball dispersion is still achieved. Thus, a more forgiving club head design is achieved. As a result, golfers can feel more confident with increasing their golf club swing speed.
In addition, the center of gravity of the club head is positioned at a location to enhance performance. In the structures of the exemplary embodiments of the golf club head, the center of gravity is positioned outside of the void location of the club head, and inside the internal cavity or internal volume of the club head. In certain exemplary embodiments, the center of gravity is located between an inner surface of the ball striking face and an inner surface of the base support wall, or within the internal cavity.
In addition, the geometry and structure of the golf club head provides enhanced sound characteristics. With the structure of the crown, geometric weighting feature as well as the internal support members as described above such as in
In addition, the moveable weight mechanisms employed herein provide additional options for distributing weight providing further adjustability of moment of inertia and center of gravity properties. For example, embodiments described herein providing weights that can be further moved towards the rear of the club head at the heel and toe can provide more easily lofted golf shots. Weights can also be more towards the front of the club head to provide more boring shots, such as those desired in higher wind conditions. Weights can also be positioned more towards a crown or sole of the golf club head in certain embodiments. Such moveable weighting features provide additional customization. Finally, various adjustable connection mechanisms can be used with the club heads to provide club head adjustability regarding face angle, loft angle and/or lie angle. Such adjustable connection mechanisms are further disclosed, for example, in U.S. Ser. No. 13/593,058, which application is incorporated by reference herein. Other adjustable mechanisms could also be used. A further embodiment utilizing the adjustable connection mechanism described above allows the golfer to adjust parameters of the golf club such as loft angle of the golf club. Certain golfers desire a lower loft angle setting such as but not limited to 7.5 degrees, 8 degrees, or 8.5 degrees or even 9 degrees. Such low loft angle settings may provide lower ball spin at ball impact. The moveable weight mechanisms, such as shown in
As discussed, the golf club head 200 has the strategically positioned uninterrupted area 320.

Thus, while there have been shown, described, and pointed out fundamental novel features of various embodiments, it will be understood that various omissions, substitutions, and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit and scope of the invention. For example, it is expressly intended that all combinations of those elements and/or steps which perform substantially the same function, in substantially the same way, to achieve the same results are within the scope of the invention. Substitutions of elements from one described embodiment to another are also fully intended and contemplated. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
