Description
2 1 0 5 8 3 0 GO~F CLUB HEAD WITH WEIGHT PAD
BACKGROUND OF THE INVENTION
This invention relates generally to golf clubs and, in particular, to a golf club head with a weight pad for increasing resistance to rotation or twisting of the golf club head on off-center impacts with golf balls.
Golf clubs known as "woods" traditionally have a head made of a suitable wooden material such as maple or persimmon attached to one end of an elongated shaft. These wooden club heads are usually solid and are shaped with their weight properly distributed about their center of gravity to maximize performance. Golf club "wood" heads have also been formed of suitable metals such as stainless steel. Metal heads are usually hollow. Various attempts have been made to distribute weight in metal heads with respect to their center of gravity so that performance is maximized. Such attempts have included placing different types and numbers of weight members at different locations inside the metal heads.
Examples of such attempts are disclosed in prior~U.S. Patent Nos. 1,167,106 to Palmer; 1,526,438 to Scott; 1,S82,836 to Link; 5,058,895 to Igarashi; and 5,141,230 to Antonious. In the Palmer, Scott and Link patents, weight members are located directly behind the center of gravity of the club head. In the Igarashi and Antonious patents, weight members are located in heel and toe portions of the club heads.
SUMMAR~ OF THE INVENTION
The present lnvention provldes a golf club head having a center of gravity, said golf club head comprising: a hollow body having a heel portlon, a toe portlon, a top wall, a bottom wall, a side wall between said top and bottom walls, a front wall with a face for impacting a golf ball; a hosel for receiving one end of an elongated shaft; said face having a sweet spot thereon aligned with the center of gravity so that when a golf ball is impacted at said sweet spot no rotation of the club head wlll occur, sald face belng disposed forwardly of and inclined with respect to a first vertical plane containing a longitudinal axis of the elongated shaft, said face intersecting and being substantially perpendlcular to a second vertlcal plane contalnlng the center of gravlty, said second vertical plane dividing said body into sald heel and toe portlons; and a welght pad dlsposed along sald side wall ln the heel portion of the body rearwardly of sald flrst vertical plane and intermediate said hosel and sald second vertical plane, said weight pad providing the golf club head with increased resistance to horizontal rotation about a vertlcal axls that extends through the center of gravlty when the club head impacts a golf ball on the face at off-center points spaced laterally of the sweet spot.
In the preferred embodiment of the golf club head, the body side wall has a length dimension measured between the first vertical plane and a third vertical plane whlch ls disposed generally parallel to the first vertical plane while belng located rearwardly of both the front wall and the hosel, and the welght pad has an elongate shape ln a directlon extendlng along the length dlmenslon of the slde wall.
Preferably the welght pad welghs between 5 and 15 grams, and ls dlvlded lnto two substantlally equal parts by a fourth vertlcal plane whlch lntersects the flrst and second vertlcal planes at approxlmately 45 degrees. The flrst, second and fourth vertlcal planes lntersect at a common axls.
DESCRIPTION OF THE DRAWINGS
Flg. 1 ls a bottom vlew of a golf club head havlng a welght pad accordlng to the present lnventlon;
Flg. 2 ls an enlarged sectlonal vlew taken along llnes 2-2 ln Flg. l; and Flg. 3 ls a rear elevatlonal vlew of the golf club head shown ln Flg. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referrlng to Flg. 1, a golf club head 10 lncludes a hollow body 12 and a hosel 14 preferably formed of a sultable metal such as stalnless steel. The body 12 has a heel portlon 12a, a toe portlon 12b, a top wall 16, a bottom wall 18, a slde wall 20 between the top and bottom walls 16 and 18, and a front wall 22 havlng a face 24 arranged for contactlng a golf ball. Located on the face 24 ls a generally central polnt 26 known as a "sweet spot" whlch ls allgned wlth a club head center of gravlty 28. When the face 24 lmpacts a golf ball at the sweet spot 26, no rotatlon or twlstlng of the club head 10 wlll occur. One end of an elongated shaft 30 ls recelved ln the hosel 14.
The club head face 24 ls dlsposed forwardly of and incllned wlth respect to a flrst vertlcal plane A whlch contalns the longltudlnal axls 32 of the shaft 30. The face 24 lntersects and ls substantlally perpendlcular to a second vertlcal plane B whlch contalns the sweet spot 26 and the center of gravlty 28. The vertlcal plane B dlvldes the body 12 lnto the heel and toe portlons 12a, 12b. The slde wall 20 of the body 12 has a length dlmenslon measured between the flrst vertlcal plane A and a thlrd vertlcal plane C whlch ls generally parallel to the vertlcal plane A whlle belng located rearwardly of both the hosel 14 and the front wall 22. The vertlcal plane C contalns a rearwardmost polnt 21 on the side wall 20.
The body 12 has a generally teardrop shape with a large percentage of its weight located in the toe portion 12b thereof and a small percentage of its welght located in the heel portion 12a thereof. The teardrop shape of the body 12 makes the club head 10 very aerodynamic on a golfer's downswlng. Upon lmpact wlth a golf ball at any off-center points (such as points 34, 36) on the face 24 spaced laterally of the sweet spot 26, the extra welght ln the body toe portion 12b increases horlzontal rotatlon or twlstlng of the club head 10 (ln elther a clockwlse dlrectlon or ln a counterclockwlse dlrectlon when vlewed ln Flg. 1) about a vertlcal axls that extends through the center of gravlty 28. For example, upon lmpact at the off-center point 34, the horlzontal club head rotatlon causes the face 24 to close whlch results in a fade type spin on the golf ball. Upon impact at the off-center polnt 36, the horlzontal club head rotatlon or twlstlng causes the face 24 to open whlch results ln a hook type spln on the golf ball.
It has been determlned that a properly located weight member wlll provlde the golf club head 10 wlth lncreased reslstance to horlzontal rotatlon or twlstlng upon off-center lmpacts wlth golf balls. Thls lncreased reslstance to horlzontal rotatlon or twlstlng of the club head 10 results ln less fade type spln and less hook type spln on golf balls whlch are lmpacted at off-center polnts on the face 24.
Accordlngly, a welght pad 38 ls formed generally along the lnslde of the body side wall 20 ln the heel portlon 12a of the body 12. The welght pad 38 ls located rearwardly of the flrst vertlcal plane A and lntermedlate the hosel 14 and the second vertlcal plane B. The welght pad 38, whlch preferably welghs between S and 15 grams, ls arranged so that lt ls dlvlded lnto two substantlally equal parts by a fourth vertlcal plane D
that lntersects the vertlcal planes A and B at approxlmately 45 degrees. The flrst, second and fourth vertlcal planes A, B
and D lntersect at common axls E.
Durlng testlng of the club head 10, the welght pad ,~
was located in three different locations inside the body 12 along the length dimension of the side wall 20. A first test location for the weight pad 38 was along the side wall 20 in the body toe portion 12b. This first test location created more fade type spin and more hook type spin on golf balls on off-center impacts by causing the club head face 24 to open and close farther. In other words, golf balls deviated farther from their intended path of travel when the weight pad 38 was located in the toe portion 12b. A second test location for the weight pad 38 was directly behind the sweet spot 26 and the center of gravity 28. This second test location had no effect on the fade type spin and the hook type spin on golf balls. That is, with the weight pad 38 located directly behind the center of gravity, golf balls travelled along the same path as when the weight pad 38 is eliminated from the club head 10. A third test location for the weight pad 38 was along the side wall 20 in the body heel portion 12a. This third test location created less fade spin and less hook spin on golf balls by resisting opening and closing of the face 24 on off-center impacts with golf balls.
Therefore, golf balls travel closer to their intended path when the weight pad 38 is located as shown in Figs. 1-3.
It will be understood that the top, bottom and side walls 16, 18 and 20 each have a thickness between 0.036 and 0.040 inch. The front wall 22 has a thickness between 0.128 and 0.135 inch.
BACKGROUND OF THE INVENTION
This invention relates generally to golf clubs and, in particular, to a golf club head with a weight pad for increasing resistance to rotation or twisting of the golf club head on off-center impacts with golf balls.
Golf clubs known as "woods" traditionally have a head made of a suitable wooden material such as maple or persimmon attached to one end of an elongated shaft.

In the Palmer, Scott and Link patents, weight members are located directly behind the center of gravity of the club head. In the Igarashi and Antonious patents, weight members are located in heel and toe portions of the club heads.
SUMMAR~ OF THE INVENTION
The present lnvention provldes a golf club head having a center of gravity, said golf club head comprising: a hollow body having a heel portlon, a toe portlon, a top wall, a bottom wall, a side wall between said top and bottom walls, a front wall with a face for impacting a golf ball; a hosel for receiving one end of an elongated shaft; said face having a sweet spot thereon aligned with the center of gravity so that when a golf ball is impacted at said sweet spot no rotation of the club head wlll occur, sald face belng disposed forwardly of and inclined with respect to a first vertical plane containing a longitudinal axis of the elongated shaft, said face intersecting and being substantially perpendlcular to a second vertlcal plane contalnlng the center of gravlty, said second vertical plane dividing said body into sald heel and toe portlons; and a welght pad dlsposed along sald side wall ln the heel portion of the body rearwardly of sald flrst vertical plane and intermediate said hosel and sald second vertical plane, said weight pad providing the golf club head with increased resistance to horizontal rotation about a vertlcal axls that extends through the center of gravlty when the club head impacts a golf ball on the face at off-center points spaced laterally of the sweet spot.
In the preferred embodiment of the golf club head, the body side wall has a length dimension measured between the first vertical plane and a third vertical plane whlch ls disposed generally parallel to the first vertical plane while belng located rearwardly of both the front wall and the hosel, and the welght pad has an elongate shape ln a directlon extendlng along the length dlmenslon of the slde wall.
Preferably the welght pad welghs between 5 and 15 grams, and ls dlvlded lnto two substantlally equal parts by a fourth vertlcal plane whlch lntersects the flrst and second vertlcal planes at approxlmately 45 degrees. The flrst, second and fourth vertlcal planes lntersect at a common axls.
DESCRIPTION OF THE DRAWINGS
Flg. 1 ls a bottom vlew of a golf club head havlng a welght pad accordlng to the present lnventlon;
Flg. 2 ls an enlarged sectlonal vlew taken along llnes 2-2 ln Flg. l; and Flg. 3 ls a rear elevatlonal vlew of the golf club head shown ln Flg. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referrlng to Flg. 1, a golf club head 10 lncludes a hollow body 12 and a hosel 14 preferably formed of a sultable metal such as stalnless steel. The body 12 has a heel portlon 12a, a toe portlon 12b, a top wall 16, a bottom wall 18, a slde wall 20 between the top and bottom walls 16 and 18, and a front wall 22 havlng a face 24 arranged for contactlng a golf ball. Located on the face 24 ls a generally central polnt 26 known as a "sweet spot" whlch ls allgned wlth a club head center of gravlty 28. When the face 24 lmpacts a golf ball at the sweet spot 26, no rotatlon or twlstlng of the club head 10 wlll occur. One end of an elongated shaft 30 ls recelved ln the hosel 14.
The club head face 24 ls dlsposed forwardly of and incllned wlth respect to a flrst vertlcal plane A whlch contalns the longltudlnal axls 32 of the shaft 30. The face 24 lntersects and ls substantlally perpendlcular to a second vertlcal plane B whlch contalns the sweet spot 26 and the center of gravlty 28. The vertlcal plane B dlvldes the body 12 lnto the heel and toe portlons 12a, 12b. The slde wall 20 of the body 12 has a length dlmenslon measured between the flrst vertlcal plane A and a thlrd vertlcal plane C whlch ls generally parallel to the vertlcal plane A whlle belng located rearwardly of both the hosel 14 and the front wall 22. The vertlcal plane C contalns a rearwardmost polnt 21 on the side wall 20.
The body 12 has a generally teardrop shape with a large percentage of its weight located in the toe portion 12b thereof and a small percentage of its welght located in the heel portion 12a thereof. The teardrop shape of the body 12 makes the club head 10 very aerodynamic on a golfer's downswlng. Upon lmpact wlth a golf ball at any off-center points (such as points 34, 36) on the face 24 spaced laterally of the sweet spot 26, the extra welght ln the body toe portion 12b increases horlzontal rotatlon or twlstlng of the club head 10 (ln elther a clockwlse dlrectlon or ln a counterclockwlse dlrectlon when vlewed ln Flg. 1) about a vertlcal axls that extends through the center of gravlty 28. For example, upon lmpact at the off-center point 34, the horlzontal club head rotatlon causes the face 24 to close whlch results in a fade type spin on the golf ball. Upon impact at the off-center polnt 36, the horlzontal club head rotatlon or twlstlng causes the face 24 to open whlch results ln a hook type spln on the golf ball.
It has been determlned that a properly located weight member wlll provlde the golf club head 10 wlth lncreased reslstance to horlzontal rotatlon or twlstlng upon off-center lmpacts wlth golf balls. Thls lncreased reslstance to horlzontal rotatlon or twlstlng of the club head 10 results ln less fade type spln and less hook type spln on golf balls whlch are lmpacted at off-center polnts on the face 24.
Accordlngly, a welght pad 38 ls formed generally along the lnslde of the body side wall 20 ln the heel portlon 12a of the body 12. The welght pad 38 ls located rearwardly of the flrst vertlcal plane A and lntermedlate the hosel 14 and the second vertlcal plane B. The welght pad 38, whlch preferably welghs between S and 15 grams, ls arranged so that lt ls dlvlded lnto two substantlally equal parts by a fourth vertlcal plane D
that lntersects the vertlcal planes A and B at approxlmately 45 degrees. The flrst, second and fourth vertlcal planes A, B
and D lntersect at common axls E.
Durlng testlng of the club head 10, the welght pad ,~
was located in three different locations inside the body 12 along the length dimension of the side wall 20. A first test location for the weight pad 38 was along the side wall 20 in the body toe portion 12b. This first test location created more fade type spin and more hook type spin on golf balls on off-center impacts by causing the club head face 24 to open and close farther. In other words, golf balls deviated farther from their intended path of travel when the weight pad 38 was located in the toe portion 12b. A second test location for the weight pad 38 was directly behind the sweet spot 26 and the center of gravity 28. This second test location had no effect on the fade type spin and the hook type spin on golf balls. That is, with the weight pad 38 located directly behind the center of gravity, golf balls travelled along the same path as when the weight pad 38 is eliminated from the club head 10. A third test location for the weight pad 38 was along the side wall 20 in the body heel portion 12a. This third test location created less fade spin and less hook spin on golf balls by resisting opening and closing of the face 24 on off-center impacts with golf balls.
Therefore, golf balls travel closer to their intended path when the weight pad 38 is located as shown in Figs. 1-3.
It will be understood that the top, bottom and side walls 16, 18 and 20 each have a thickness between 0.036 and 0.040 inch. The front wall 22 has a thickness between 0.128 and 0.135 inch.
