DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Fig. 1, a golf club 10 incorporating the present invention includes a head 12, a hosel 14 and a shaft 16. Head 12 is comprised of a hollow body 18 made of a first material such as titanium having a high shear modulus of elasticity. The hollow body 18 has a top wall 20, a bottom wall 22, a side wall 24 connecting the top and side walls 20 and 22, and a front wall 26 arranged for impacting a golf , ball. Further, the head 12 has a heel end 12a and a toe end 12b.
A bore 28 is provided in the heel end 12a of the head 12 extending downwardly from the body top wall 20 toward the body bottom wall 22. The bore 28 has a top end 28a which is open and a bottom 28b which is closed. As seen in Fig. 3, the top end 28a of the bore 28 is substantially flush with the top wall 20 of the body 18, and the bore bottom end 28b is spaced from the bottom wall 22 of the body 18. The bore 28 is defined by a lateral wall 30 connected with the side wall 24 of the body 18, and an end wall 32 connected with the lateral wall 30.
The hosel 14 is formed of a second material such as plastic having a low shear modulus of elasticity. Hosel 14 includes an upper portion 34 that extends upwardly from the top wall 20 of the body 18 and a lower portion 36 that is inserted into the bore 28. The upper and lower hosel portions 34, 36 are separated by a parting line 38. The hosel 14 also has a substantially longitudinal passage 40 extending through its upper and lower portions 34, 36. When the golf club 10 is assembled as shown in Fig. 3, the hosel 14 contacts the bottom end 32 of the bore 28.
The shaft 16 is made of a third material, preferably graphite, having a low shear modulus of elasticity. Shaft 16 has a tip end 17 received in the hosel passage 40. The shaft , . . .
CA 022~40~4 1998-11-12 tip end 17 extends completely through the hosel 14 and contacts the bottom end 32 of the bore 28. In the preferred embodiment of the golf club 10, the shear modulus of elasticity of the hosel 14 is much closer to the shear elastic modulus of the shaft 16 than to the shear elastic modulus of the head 12. This relationship of elastic moduli causes the hosel 14 to absorb much of the shock resulting from the head 12 striking a golf ball on the front face 26. Therefore, less shock is transmitted to the shaft 16 which prevents breakage of the shaft 16 and permits the shaft 16 to have a weaker tip end 17 which reduces cost.
Referring to Figs. 4-8, it is seen that the lower portion 36 of the hosel 14 has an irregular outside shape defined by a generally arcuate surface 14a covering its front and sides, and a generally flat surface 14b covering its back. The bore 28 in the head 12 has a complementary irregular inside shape defined by a generally arcuate surface 28a and a generally flat surface 28b. Therefore, the hosel 14 may be inserted into the bore 28 in only one orientation which ensures exact alignment of the shaft 16 relative to the head 12. In that orientation, the generally arcuate surfaces 14a, 28a of the hosel 14 and the bore 28 mate with each other, and the generally flat surfaces 14b, 28b of the hosel 14 and the bore 28 also mate with each other.
CA 022~40~4 1998-11-12 Since the hosel 14 is made of softer material than the head 12, the hosel 14 has a cushioning effect on the shaft 16.
This cushioning effect significantly reduces the amount of vibration that is transmitted to the shaft 16 which increases shaft life.
Referring to Figs. 8-10, it will be understood that the front wall 26 of the body 18 is reinforced by providing it with increased thickness near its geometric center C. The front wall 26 varies in thickness in a first plane A that is disposed substantially horizontally between the top and bottom walls 20, 22 of the body 18. The front wall 26 also varies in thickness in a second plane B that is disposed substantially vertically between the head heel and toe ends 12a, 12b.
As seen in Figs. 9 and 10, the front wall 26 has increased thickness along an axis X where the planes A and B
intersect. Since this axis X extends through the geometric center C of the front wall 26, the increased thickness of the front wall 26 is greatest at the geometric center C. The front wall increased thickness gradually decreases in a first direction extending from the axis X to the top wall 20, in a second direction extending from the axis X to the bottom wall 22, in a third direction extending from the axis X to the heel end 12a, and in a fourth direction extending from the axis X
to the toe end 12b.
CA 022~40~4 1998-11-12 The head front wall 26 has a first thickness dimension T1 at its geometric center C, a second thickness dimension T2 adjacent the heel and toe ends 12a, 12b, and a third thickness dimension T3 adjacent the top and bottom walls 20, 22. The thickness dimension T1 is greater than the thickness dimensions T2 and T3; and the thickness dimensions T2 and T3 may be equal. In the preferred embodiment, the thickness dimension T1 is between 0.130 and 0.180 inch, the thickness dimension T2 is between 0.040 and 0.125 inch, and the thickness dimension T3 is between 0.040 and 0.125 inch.
By reinforcing the front wall 26 with the increased thickness T1 as described above, front wall 26 is strengthened at its geometric center C where loading is the greatest when impacting a golf ball. Also, by providing the front wall 26 with the decreased thickness dimensions T2 and T3, mass is redistributed to other parts of the head 12 to enhance performance of the golf club 10.
Referring to Figs. 11-13, another embodiment of the head 12 according to the present invention is shown wherein the side wall 24 of the hollow body 18 has a recess 42 formed therein between the heel and toe ends 12a, 12b substantially opposite the front wall 26. The recess 42 has a continuous side wall 42a and an end wall 42b. A back weighting member 44 having a predetermined volume is disposed in the recess 42.
The back weighting member 44 is selected from a plurality of .
CA 022~40~4 1998-11-12 back weighting members (not shown) that have the same predetermined volume but have different densities and thus different weights. Therefore, the desired weight of the body 18 may be adjusted without changing the predetermined volume of the back weighting member 44. By selecting a back weighting member 44 of the proper weight, manufacturing tolerances can be overcome and swingweight of the golf club 10 may be adjusted in a simple effective manner. The back weighting member 44 is preferably formed of a suitable plastic with metal fillers.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Fig. 1, a golf club 10 incorporating the present invention includes a head 12, a hosel 14 and a shaft 16. Head 12 is comprised of a hollow body 18 made of a first material such as titanium having a high shear modulus of elasticity. The hollow body 18 has a top wall 20, a bottom wall 22, a side wall 24 connecting the top and side walls 20 and 22, and a front wall 26 arranged for impacting a golf , ball. Further, the head 12 has a heel end 12a and a toe end 12b.
A bore 28 is provided in the heel end 12a of the head 12 extending downwardly from the body top wall 20 toward the body bottom wall 22. The bore 28 has a top end 28a which is open and a bottom 28b which is closed. As seen in Fig. 3, the top end 28a of the bore 28 is substantially flush with the top wall 20 of the body 18, and the bore bottom end 28b is spaced from the bottom wall 22 of the body 18. The bore 28 is defined by a lateral wall 30 connected with the side wall 24 of the body 18, and an end wall 32 connected with the lateral wall 30.
The hosel 14 is formed of a second material such as plastic having a low shear modulus of elasticity. Hosel 14 includes an upper portion 34 that extends upwardly from the top wall 20 of the body 18 and a lower portion 36 that is inserted into the bore 28. The upper and lower hosel portions 34, 36 are separated by a parting line 38. The hosel 14 also has a substantially longitudinal passage 40 extending through its upper and lower portions 34, 36. When the golf club 10 is assembled as shown in Fig. 3, the hosel 14 contacts the bottom end 32 of the bore 28.
The shaft 16 is made of a third material, preferably graphite, having a low shear modulus of elasticity. Shaft 16 has a tip end 17 received in the hosel passage 40. The shaft , . . .
CA 022~40~4 1998-11-12 tip end 17 extends completely through the hosel 14 and contacts the bottom end 32 of the bore 28. In the preferred embodiment of the golf club 10, the shear modulus of elasticity of the hosel 14 is much closer to the shear elastic modulus of the shaft 16 than to the shear elastic modulus of the head 12. This relationship of elastic moduli causes the hosel 14 to absorb much of the shock resulting from the head 12 striking a golf ball on the front face 26. Therefore, less shock is transmitted to the shaft 16 which prevents breakage of the shaft 16 and permits the shaft 16 to have a weaker tip end 17 which reduces cost.
Referring to Figs. 4-8, it is seen that the lower portion 36 of the hosel 14 has an irregular outside shape defined by a generally arcuate surface 14a covering its front and sides, and a generally flat surface 14b covering its back. The bore 28 in the head 12 has a complementary irregular inside shape defined by a generally arcuate surface 28a and a generally flat surface 28b. Therefore, the hosel 14 may be inserted into the bore 28 in only one orientation which ensures exact alignment of the shaft 16 relative to the head 12. In that orientation, the generally arcuate surfaces 14a, 28a of the hosel 14 and the bore 28 mate with each other, and the generally flat surfaces 14b, 28b of the hosel 14 and the bore 28 also mate with each other.
CA 022~40~4 1998-11-12 Since the hosel 14 is made of softer material than the head 12, the hosel 14 has a cushioning effect on the shaft 16.
This cushioning effect significantly reduces the amount of vibration that is transmitted to the shaft 16 which increases shaft life.
Referring to Figs. 8-10, it will be understood that the front wall 26 of the body 18 is reinforced by providing it with increased thickness near its geometric center C. The front wall 26 varies in thickness in a first plane A that is disposed substantially horizontally between the top and bottom walls 20, 22 of the body 18. The front wall 26 also varies in thickness in a second plane B that is disposed substantially vertically between the head heel and toe ends 12a, 12b.
As seen in Figs. 9 and 10, the front wall 26 has increased thickness along an axis X where the planes A and B
intersect. Since this axis X extends through the geometric center C of the front wall 26, the increased thickness of the front wall 26 is greatest at the geometric center C. The front wall increased thickness gradually decreases in a first direction extending from the axis X to the top wall 20, in a second direction extending from the axis X to the bottom wall 22, in a third direction extending from the axis X to the heel end 12a, and in a fourth direction extending from the axis X
to the toe end 12b.
CA 022~40~4 1998-11-12 The head front wall 26 has a first thickness dimension T1 at its geometric center C, a second thickness dimension T2 adjacent the heel and toe ends 12a, 12b, and a third thickness dimension T3 adjacent the top and bottom walls 20, 22. The thickness dimension T1 is greater than the thickness dimensions T2 and T3; and the thickness dimensions T2 and T3 may be equal. In the preferred embodiment, the thickness dimension T1 is between 0.130 and 0.180 inch, the thickness dimension T2 is between 0.040 and 0.125 inch, and the thickness dimension T3 is between 0.040 and 0.125 inch.
By reinforcing the front wall 26 with the increased thickness T1 as described above, front wall 26 is strengthened at its geometric center C where loading is the greatest when impacting a golf ball. Also, by providing the front wall 26 with the decreased thickness dimensions T2 and T3, mass is redistributed to other parts of the head 12 to enhance performance of the golf club 10.
Referring to Figs. 11-13, another embodiment of the head 12 according to the present invention is shown wherein the side wall 24 of the hollow body 18 has a recess 42 formed therein between the heel and toe ends 12a, 12b substantially opposite the front wall 26. The recess 42 has a continuous side wall 42a and an end wall 42b. A back weighting member 44 having a predetermined volume is disposed in the recess 42.
The back weighting member 44 is selected from a plurality of .
CA 022~40~4 1998-11-12 back weighting members (not shown) that have the same predetermined volume but have different densities and thus different weights. Therefore, the desired weight of the body 18 may be adjusted without changing the predetermined volume of the back weighting member 44. By selecting a back weighting member 44 of the proper weight, manufacturing tolerances can be overcome and swingweight of the golf club 10 may be adjusted in a simple effective manner. The back weighting member 44 is preferably formed of a suitable plastic with metal fillers.
