Definitions
- the present invention relates to golf clubs and, in particular, to fairway woods.
- the invention especially relates to fairway woods having a head comprised of a stainless steel body and a titanium front face.
- Fairway woods are known whose head includes a titanium alloy faceplate attached to a stainless steel body.
- the use of titanium alloy for the faceplate reduces the weight of the club head, enabling faster head speed to be attained, as well as enabling the front face to perform a spring action for increased distance.
- a titanium alloy faceplate 30 of variable thickness whose center region is thicker than the outer peripheral portion thereof. That enables the club face to perform an enhanced spring action which further increases the distance of a fairway shot. It is known to attach such a variable thickness faceplate to the body by a tungsten inert gas (TIG) welding along the thin outer peripheral portion of the faceplate at a location spaced from the upper and lower edges 31 , 32 of the club face. The welding action causes the welded part of the thin peripheral portion to loose its beneficial flexibility. Since the height of the faceplate is relatively short, even a partial loss of flexibility has a significant adverse effect on the overall springiness of the faceplate.

- the face member 14 is cup-shaped in that it comprises a front portion 16 and a rim or lip 18 projecting rearwardly from an outer periphery of the front portion.
- a rearwardly-facing rear edge 18 a of the rim 18 (see FIG. 10 ) is bonded by silver-nickel brazing 22 to a forwardly-facing seat 20 of the body 12 .
- the seat 20 is bordered inwardly by a forwardly-projecting ridge 21 of the body which extends endlessly around the seat 20 .
- the forwardly facing seat of the body could comprise a forwardly open recess 20 ′ disposed between two endless ridges 21 ′, 21 ′′ of the body as shown in FIG. 3 a .
- the rear edge of the rim 18 would include a rearwardly projecting rib 22 ′ that fits into the recess 21 ′.
- the rear edge of the rim would be bonded to the seat by silver-nickel brazing.
- the positions of the recess 21 ′ and the rib 22 ′ could be reversed, i.e., the recess could be disposed in the rim, and the rib on the body.
- the body 12 is formed of stainless steel, most preferably 17-4 stainless steel, and the face member 14 is formed of a titanium alloy, most preferably 15-3-3-3 beta titanium, although other stainless steel materials and other titanium alloys could be used.
- a cup-shaped face member provides a vertically longer “sweet” area of the front face as compared to a prior art TIG (tungsten inert gas) welded-on flat titanium faceplate 30 ( FIG. 9 ). That is, in FIG. 8 it can be seen that the height H of the sweet area of the cup-shaped face member 14 extends virtually from the top edge 31 to the bottom edge 32 of the club's front face, whereas FIG. 9 shows that the height H′ of the sweet area of the prior art faceplate 30 terminates short of the top and bottom edges.
- TIG tungsten inert gas
- the front portion 16 of the face member 14 is preferably of variable thickness (see FIGS. 8 and 10 ) in that the center region 16 a thereof is thicker than the outer peripheral border portion 16 b thereof, whereby the face member performs a robust spring action upon impact, to maximize the ball's travel distance.
- the center portion could be 2.6 mm thick, and the outer peripheral portion 1.6 mm thick. It will be appreciated that if a prior art variable-thickness faceplate 30 is attached by a TIG weld to a body, the weld will coincide with a thin outer portion of the faceplate, thereby stiffening that welded thin outer portion and reducing its flexibility.
- the center region of the front portion 16 could be of a constant larger-thickness surrounded by a constant smaller-thickness border portion.
- top, bottom, and sides of the club's front face are formed by the thin border portion of the face member 14 , rather than by the thicker and heavier stainless material of the club body 12 A (as in the prior art shown in FIG. 9 ), there will occur a reduction in weight of the club head.
- An additional weight reduction occurs as a result of the use of silver-nickel brazing to attach the face member 14 , which brazing is lighter (e.g., on the order of about seven grams) as compared to the TIG weld used in the prior art.
- the thus-achieved reduction in weight can serve to lower the center of gravity of the club head and thereby lengthen the length x of the effective hitting area of the front face, as shown in FIG. 7 . Accordingly, the occurrence of backspin on a hit ball can be reduced.
- the center of gravity becomes located deeper in the club (i.e., the distance GD in FIG. 7 is increased), thereby promoting greater elevation of a hit ball, and more forgiveness of off-center hits.
- the large, generally rectangular shape of the front face of the club also provides greater forgiveness of off-center hits as compared to smaller-area trapezoidal-shaped front faces of prior art fairway clubs.
- a pair of weights 40 , 40 in the form of rods are attached at the toe and heel, respectively, of the body 12 .
- those rods are welded in respective holes formed in the toe side and heel side of the body, the axes of the holes extending in the fore-aft direction of the club head.
- Each rod 40 preferably comprises a tungsten nickel rod having a weight of about 4 grams, for example. The effect of those rods is to increase the weight of the toe and heel regions and thereby increase the inertia of those regions during a swing in order to better resist the tendency for the club head to twist in the event of an off-center hit.
- a pair of weights 44 may be attached in the sole 46 of the body near the front face and on opposite sides of a front-to-rear centerline CL of the club head.
- Each weight 44 could preferably comprise a tungsten-nickel screw having a weight of 10 grams, for example, that is permanently bonded in the body 12 . The effect of those weights 44 is to advantageously lower the center of gravity of the club head.
- the hosel 50 comprises a stainless steel inner portion 52 (integral with the body 12 ) and a titanium alloy outer sleeve portion 54 welded to the inner portion.
- the outer sleeve portion 54 preferably comprises an alpha-beta titanium alloy such as 6-4 titanium, for example. This can reduce the weight of the top of the head by about 3 grams, thereby advantageously lowering the center of gravity.
- FIG. 11 depicts schematically a fairway wood club head profile according to the invention wherein the portion 60 of the sole disposed in a region extending rearwardly from about a vertical center line L of the head to the back end 62 is inclined upwardly (cambered) as shown in FIG. 11 , whereby the length of the horizontal flat ground-engaging portion 64 of the sole is minimized.
- This short flat horizontal portion 64 makes it easier for the head to rest on the ground. Also, it is easier to make the club head airborne at the start of the backswing since the ground-engaging area of the sole has been minimized in the rear half of the head.
- FIG. 12 depicts the sole 72 of a prior art head which exhibits a substantially longer ground flat horizontal engaging area and is more difficult to make airborne.
- the club head 10 is preferably used with a conventional triple-action shaft (not shown) which includes a tip zone to which the club's hosel is attached, a butt zone which is gripped by a player, and a middle zone disposed between the tip zone and the butt zone.
- the tip zone is the most flexible; the butt zone is more rigid (less flexible) than the tip zone; and the middle zone is more rigid than the butt zone in order to: control the stability of the swing, improve the directional accuracy of a shot, and increase the head speed.
Abstract
Description
- The present invention claims priority under 35 U.S.C. §119 and/or §365 to U.S. Provisional Application Serial No. 60,633,322 filed on Dec. 6, 2004.
- The present invention relates to golf clubs and, in particular, to fairway woods. The invention especially relates to fairway woods having a head comprised of a stainless steel body and a titanium front face.
- Fairway woods are known whose head includes a titanium alloy faceplate attached to a stainless steel body. The use of titanium alloy for the faceplate reduces the weight of the club head, enabling faster head speed to be attained, as well as enabling the front face to perform a spring action for increased distance.
- As shown in
FIG. 9 , it is also known to employ atitanium alloy faceplate 30 of variable thickness whose center region is thicker than the outer peripheral portion thereof. That enables the club face to perform an enhanced spring action which further increases the distance of a fairway shot. It is known to attach such a variable thickness faceplate to the body by a tungsten inert gas (TIG) welding along the thin outer peripheral portion of the faceplate at a location spaced from the upper andlower edges - It is also known that optimum directional accuracy of a wood shot can be attained when impact occurs at the center sweet spot of the club face, but that an off-center hit which is offset toward the toe or heel of the club, can cause the club to twist, thereby causing the shot to hook or slice.
- Therefore, it would be desirable to minimize or obviate the above-described disadvantages and provide a fairway wood that is capable of producing longer and more accurate golf shots, even in the case of an off-center hit.
- It would also be desirable to provide a fairway wood that is more forgiving of off-center hits.
- It would be further desirable to provide a fairway wood that reduces backspin and increases the elevation of a struck ball.
- It would moreover be desirable to provide a fairway wood that can more easily become airborne at the start of the backswing.
- One aspect of the present invention relates to a fairway wood which comprises a body and a face member attached to a front side of the body. The face member includes a front portion and a rim projecting rearwardly from an outer periphery of the front portion. The front portion defines a front face of the wood. A rear portion of the rim is bonded to a seat of the body. The body comprises stainless steel and the face member comprises titanium, wherein a rear end edge of the rim is bonded to the seat of the body by silver-nickel brazing.
- Preferably, the front portion of the face member is thicker than an outer peripheral portion thereof.
- Preferably, first and second weights are mounted in a sole of the body on opposite sides of a horizontal front-to-rear centerline of the body.
- Preferably, third and fourth weights are mounted in a toe portion and a heel portion, respectively, of the body.
- Preferably, the body comprises stainless steel, and a hosel is provided which comprises a stainless steel cylindrical inner portion defined by part of the body, and a cylindrical outer sleeve portion telescoped onto and bonded to the inner portion. The outer sleeve portion is formed of a titanium alloy.
- Another aspect of the invention relates to a fairway wood which comprises a body, a face member attached to a front side of the body, and four weights mounted in the body. First and second ones of the weights are mounted in a sole of the body on opposite sides of a horizontal front-to-rear centerline of the body. Third and fourth ones of the weights are mounted in toe and heel portions, respectively, of the body.
- Another aspect of the invention relates to a fairway wood which comprises a body and a face member attached to a front side of the body. The body includes a sole. A front portion of the sole is flat and horizontal, and a rear portion of the sole is inclined upwardly and rearwardly from a location substantially midway between front and rear ends of the body.
- A further aspect of the invention relates to a fairway wood which comprises a stainless steel body, a titanium alloy face member attached to a front side thereof, and a hosel comprising a stainless steel inner portion formed by part of the body, and a titanium alloy outer sleeve portion disposed around and attached to the inner portion.

FIG. 12 is a view similar toFIG. 11 of a prior art fairway wood. - Depicted in
FIGS. 1-6 is ahead 10 of a fairway wood comprising astainless steel body 12, and a titaniumalloy face member 14 attached to a front side thereof. Theface member 14 is cup-shaped in that it comprises afront portion 16 and a rim orlip 18 projecting rearwardly from an outer periphery of the front portion. A rearwardly-facing rear edge 18 a of the rim 18 (seeFIG. 10 ) is bonded by silver-nickel brazing 22 to a forwardly-facingseat 20 of thebody 12. Theseat 20 is bordered inwardly by a forwardly-projectingridge 21 of the body which extends endlessly around theseat 20. - The shapes of the seat and the mating surface of the rim can vary. For example, the forwardly facing seat of the body could comprise a forwardly
open recess 20′ disposed between twoendless ridges 21′, 21″ of the body as shown inFIG. 3 a. The rear edge of therim 18 would include a rearwardly projectingrib 22′ that fits into therecess 21′. As in the case ofFIGS. 1-6 , the rear edge of the rim would be bonded to the seat by silver-nickel brazing. Alternatively, the positions of therecess 21′ and therib 22′ could be reversed, i.e., the recess could be disposed in the rim, and the rib on the body. - The
body 12 is formed of stainless steel, most preferably 17-4 stainless steel, and theface member 14 is formed of a titanium alloy, most preferably 15-3-3-3 beta titanium, although other stainless steel materials and other titanium alloys could be used. - It will be appreciated that a cup-shaped face member provides a vertically longer “sweet” area of the front face as compared to a prior art TIG (tungsten inert gas) welded-on flat titanium faceplate 30 (
FIG. 9 ). That is, inFIG. 8 it can be seen that the height H of the sweet area of the cup-shaped face member 14 extends virtually from thetop edge 31 to thebottom edge 32 of the club's front face, whereasFIG. 9 shows that the height H′ of the sweet area of theprior art faceplate 30 terminates short of the top and bottom edges. - The
front portion 16 of theface member 14 is preferably of variable thickness (seeFIGS. 8 and 10 ) in that thecenter region 16 a thereof is thicker than the outerperipheral border portion 16 b thereof, whereby the face member performs a robust spring action upon impact, to maximize the ball's travel distance. For example, the center portion could be 2.6 mm thick, and the outer peripheral portion 1.6 mm thick. It will be appreciated that if a prior art variable-thickness faceplate 30 is attached by a TIG weld to a body, the weld will coincide with a thin outer portion of the faceplate, thereby stiffening that welded thin outer portion and reducing its flexibility. That will not occur in the present invention since thebrazing 22 is spaced from the thin outer border region of thefront portion 16 by therim 18 of the faceplate. Accordingly, the spring action of the variable-thicknesstitanium face member 14 according to the present invention is not appreciably reduced by the weld could occur in the prior art. - Instead of becoming gradually thinner toward the outer periphery, as shown in
FIGS. 8 and 10 , the center region of thefront portion 16 could be of a constant larger-thickness surrounded by a constant smaller-thickness border portion. - Furthermore, since the top, bottom, and sides of the club's front face are formed by the thin border portion of the
face member 14, rather than by the thicker and heavier stainless material of theclub body 12A (as in the prior art shown inFIG. 9 ), there will occur a reduction in weight of the club head. An additional weight reduction occurs as a result of the use of silver-nickel brazing to attach theface member 14, which brazing is lighter (e.g., on the order of about seven grams) as compared to the TIG weld used in the prior art. - The thus-achieved reduction in weight can serve to lower the center of gravity of the club head and thereby lengthen the length x of the effective hitting area of the front face, as shown in
FIG. 7 . Accordingly, the occurrence of backspin on a hit ball can be reduced. - Moreover, by reducing the weight at the front face of the club head (by replacing stainless steel with titanium and silver-nickel braze), the center of gravity becomes located deeper in the club (i.e., the distance GD in
FIG. 7 is increased), thereby promoting greater elevation of a hit ball, and more forgiveness of off-center hits. The large, generally rectangular shape of the front face of the club (seeFIG. 1 ) also provides greater forgiveness of off-center hits as compared to smaller-area trapezoidal-shaped front faces of prior art fairway clubs. - Alternatively, the above-described weight savings make it possible to add weights to the club head in order to achieve various additional advantages without making the club excessively heavy. For example, as shown in
FIGS. 2 and 6 , a pair ofweights body 12. Preferably, those rods are welded in respective holes formed in the toe side and heel side of the body, the axes of the holes extending in the fore-aft direction of the club head. Eachrod 40 preferably comprises a tungsten nickel rod having a weight of about 4 grams, for example. The effect of those rods is to increase the weight of the toe and heel regions and thereby increase the inertia of those regions during a swing in order to better resist the tendency for the club head to twist in the event of an off-center hit. - A pair of
weights 44 may be attached in the sole 46 of the body near the front face and on opposite sides of a front-to-rear centerline CL of the club head. Eachweight 44 could preferably comprise a tungsten-nickel screw having a weight of 10 grams, for example, that is permanently bonded in thebody 12. The effect of thoseweights 44 is to advantageously lower the center of gravity of the club head. - To further reduce the weight of the club head, especially at the top (and thus to lower the head's center of gravity), the
hosel 50 comprises a stainless steel inner portion 52 (integral with the body 12) and a titanium alloyouter sleeve portion 54 welded to the inner portion. Theouter sleeve portion 54 preferably comprises an alpha-beta titanium alloy such as 6-4 titanium, for example. This can reduce the weight of the top of the head by about 3 grams, thereby advantageously lowering the center of gravity. -
FIG. 11 depicts schematically a fairway wood club head profile according to the invention wherein theportion 60 of the sole disposed in a region extending rearwardly from about a vertical center line L of the head to theback end 62 is inclined upwardly (cambered) as shown inFIG. 11 , whereby the length of the horizontal flat ground-engagingportion 64 of the sole is minimized. This short flathorizontal portion 64 makes it easier for the head to rest on the ground. Also, it is easier to make the club head airborne at the start of the backswing since the ground-engaging area of the sole has been minimized in the rear half of the head. - In contrast,
FIG. 12 depicts the sole 72 of a prior art head which exhibits a substantially longer ground flat horizontal engaging area and is more difficult to make airborne. - The
club head 10 is preferably used with a conventional triple-action shaft (not shown) which includes a tip zone to which the club's hosel is attached, a butt zone which is gripped by a player, and a middle zone disposed between the tip zone and the butt zone. The tip zone is the most flexible; the butt zone is more rigid (less flexible) than the tip zone; and the middle zone is more rigid than the butt zone in order to: control the stability of the swing, improve the directional accuracy of a shot, and increase the head speed. - It will be appreciated that a fairway wood according to the above-described invention exhibits a unique combination of features, including:
-
- a vertically longer “sweet” area on the front face
- a highly springy front face for increased distance
- lighter club head, and/or a club head having weight reductions in certain areas and weight increases in other strategically selected areas for better resisting twisting of the club head during impact
- a club head having a center of gravity which is situated vertically lower and/or horizontally deeper, for reduced backspin and increased elevation of a shot
- a club head which more easily becomes airborne during a backswing.
- Although the present invention has been described in connection with a preferred embodiment thereof, it will be appreciated by those skilled in the art that additions, deletions, modifications, and substitutions not specifically described may be made without departing from the spirit and scope of the invention as defined in the appended claims.
