Abstract

A golf club head includes a body having a front face for impacting a golf ball and a hosel having a bore. The body including the hosel may be made of a material such as steel. A hosel weight mounted in the hosel bore may be made of another material such as tungsten which has a greater density than the material forming the body. The hosel weight has a bore for receiving one end of a golf club shaft.

Description

    BACKGROUND
  • This invention relates generally to golf equipment and, in particular, to a golf club head.
  • U.S. Pat. No. 6,206,790 to Kubica et al discloses an iron-type golf club head with a heel portion, a toe portion and a front face arranged for impact with a golf ball. In one example, golf club heads such as shown in the Kubica et al patent may be designed so that their center of gravity is directly behind or near the golf ball impact zone which may be located at the geometric center of the front face. The moment of inertia of a golf club head can be increased by positioning more weight in the heel and toe portions of the golf club head.

  • FIGS. 7-9 are enlarged views showing different embodiments of the club head hosel.
  • DESCRIPTION
  • Referring to FIGS. 1-5, an iron-type golf club head H includes a body B with a sole 10, a top edge 12, a heel portion 14, a toe portion 16 and a front face 18 arranged for impacting a golf ball. Front face 18 extends between the heel and toe portions 14, 16. The golf club head H also includes a hosel 20 with a generally cylindrical shape on the heel portion 14 of the body B. The hosel 20 has a longitudinal axis A and a generally cylindrical bore 22 defined by its peripheral wall 26 for receiving a hosel weight 24. The hosel bore 22 is offset (i.e. not concentric) with respect to the longitudinal axis A. The heel portion 14 of the body B includes a shoulder 15 adjacent a lower end of the hosel bore 22. Mounted in the hosel 20 is the hosel weight 24. The hosel weight 24 may be fastened in the hosel 20 by conventional means such as adhesive or mechanical devices. Although FIGS. 1-5 may depict an iron-type golf club head, the apparatus and methods described herein may be applicable to other suitable types of golf club heads (e.g., driver-type golf club heads, fairway wood-type golf club heads, hybrid-type golf club heads, wedge-type golf club heads, putter-type golf club heads, etc.).
  • The hosel weight 24 has a longitudinal axis C and a generally cylindrical bore 28 which receives one end of a golf club shaft (not shown). When the hosel weight 24 is mounted in the hosel bore 22, its bore 28 is concentric with the hosel longitudinal axis A and the hosel weight 24 contacts the shoulder 15. The hosel weight bore 28 is offset (i.e., not concentric) with respect to the longitudinal axis C of the hosel weight 24. Therefore, a peripheral wall 30 of the hosel weight 24 that defines the bore 28 has a varying thickness dimension. As shown in FIG. 3, the peripheral wall 30 has a thickness dimension T1 at its thickest point and a thickness dimension T2 at its thinnest point. This results in the hosel weight 24 having significantly more mass in the vicinity of the thickness dimension T1 than in the vicinity of the thickness dimension T2. As seen in FIG. 3, the hosel weight 24 may be positioned so that its longitudinal axis C is offset from the hosel longitudinal axis A in a direction extending generally from the toe portion 16 toward the heel portion 14.
  • Alternatively, the hosel weight 24 may be rotated 180 degrees from the position shown in FIG. 3 so that its longitudinal axis C is offset from the hosel longitudinal axis A in a direction extending generally from the heel portion 14 toward the toe portion 16. It will be understood that in this alternative position, thickness dimension T1 of the hosel weight peripheral wall 30 is shifted 180 degrees from where it is located in FIG. 3. The hosel 20 may also be modified so that its bore 22 is offset with respect to the longitudinal axis A toward the body toe portion 16 instead of toward the body heel portion 14.
  • In one embodiment, the body B including the hosel 20 is made of metallic material such as steel having a first density while the hosel weight 24 is made of a metallic material such as tungsten having a second density which is greater than the first density. Alternatively, in other embodiments, the body B including the hosel 20 is made of titanium and the hosel weight is made of either zirconium or tungsten. In further embodiments, the body B including the hosel 20 is made of composite material and the hosel weight 24 is made of either metal or another composite material. It is preferred, but not required, that the material (i.e. tungsten or zirconium) forming the hosel weight 24 will have a higher density than the material (i.e. steel or titanium) forming the body B including the hosel 20.
  • The hosel weight 24 adds mass to the hosel 20 which increases the moment of inertia of the club head H. The amount of mass added to the hosel 20 is significantly increased and the moment of inertia of the club head H is significantly increased when the hosel weight 24 is made of denser material, as described above, than the body B. With the hosel weight 24 mounted in the hosel 20, the center of gravity of the club head H is shifted toward the heel portion 14 of the body B.
  • As stated above, the hosel bore 22 is offset (i.e. not concentric) with respect to the longitudinal axis A of the hosel 20. This offset results in the peripheral wall 26 of the hosel 20 having a varying thickness dimension similar to the varying thickness dimension of the peripheral wall 30 of the hosel weight 24. The combination of the hosel 20 and the hosel weight 24 results in hosel weight bore 28 being centered with respect to the outer periphery of the hosel 20 when the hosel weight 24 is mounted in the hosel bore 22.
  • Referring to FIGS. 7-9, hosels 20 a, 20 b and 20 c are similar to hosel 20 except that their bores 22 a, 22 b, and 22 c have different shapes than the cylindrical bore 22 in hosel 20. For example, the bore 22 a in hosel 20 a is rectangular and the longitudinal axis C of the hosel weight 24 is offset from the hosel longitudinal axis A. The bore 22 b in hosel 20 b is polygonal and the longitudinal axis C of the hosel weight 24 is offset from the hosel longitudinal axis A. The bore 22 c in hosel 20 c is elliptical and the longitudinal axis C of the hosel weight 24 is offset from the hosel longitudinal axis A. In the hosels 20 a, 20 b and 20 c, the peripheral walls 26 a, 26 b and 26 c that define the bores 22 a, 22 b and 22 c have a thickness dimension T1 at their thickest point and a thickness dimension T2 at their thinnest point. In each of the hosels 20 a, 20 b and 20 c, thickness dimension T1 is greater than thickness dimension T2.
  • It will be understood that when using the hosels 20 a, 20 b and 20 c, the hosel weight 24 will be modified to have an outer shape that is complimentary to the bores 22 a, 22 b and 22 c. For example, when using the hosel 20 a, the hosel weight 24 will be modified to have a generally rectangular outer shape. When using the hosel 20 b, the hosel weight 24 will be modified to have a generally polygonal outer shape and, when using the hosel 20 c, the hosel weight 24 will be modified to have a generally elliptical outer shape.
