Abstract

An adjustable golf putter utilizes an integrated indexing mechanism for the rotation of the golf club shaft in relation to the putter head. A circular portion of the hosel nests in a cavity formed in the putter head. Matching faces are impressed with a series of radiating serrations incorporated into the head and hosel and no additional parts are required. When pressed together, the serrated faces permit the hosel to rotate in discrete increments selected at time of manufacture. The putter may rotate in increments of 5 degrees for a total of 35 degrees in each direction from a center marking feature. The hosel is locked in a selected position by simply tightening the hosel screw. The putter can be adjusted for use by both right and left handed golfers without disassembly.

  • FIGS. 1-10 illustrate the preferred embodiment of the adjustable golf putter designated generally by numeral 10. FIG. 11 illustrates an alternate embodiment of the adjustable golf putter. In this preferred embodiment, a user, typically a golfer, right or left handed, will practice using the adjustable golf putter at a default set angel of zero degrees between the golf putter head 10 and the golf shaft 20. Depending on the needs of the golfer, he or she can adjust the angle between the golf putter head 10 and the golf shaft 20 by using a common Allen wrench. To loosen the hosel screw 14, golfer would turn the screw counter clockwise, which will loosen the connection between the hosel 12 and the golf putter head 10. Golfer may then adjust the angle between the golf putter head 10 and the golf shaft 20 by increments of 5 degrees to a maximum degree angle of 20 degrees in either direction. After determining the desired degree angle, golfer may fix the position of the golf putter head 10 and the hosel 14 by turning the hosel screw 14 clockwise to a locked position. In this preferred embodiment, the golfer will typically use the guide selection marking 18 to precisely adjust the hosel 12 to a corresponding angle selection marking 16. Both the guide selection marking 18 and the angle selection markings 16 are also used as reference points to assist the golfer in remembering exactly what degree angle the golfer likes or dislikes.
  • As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
  • With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
  • According to yet another embodiment of the present invention, an adjustable clubhead assembly 30 and an adjustable golf club 32 are provided. As mentioned herein, the golf club 32 of embodiments of the present invention may be formed utilizing an elongate shaft 20. FIG. 12 illustrates the shaft 20 in dashed lines. The shaft 20 defines a distal end 34 a shaft axis 36. As is known in the art, the distal end 34 of the shaft 20 may generally taper from a first shaft circumference to a second shaft circumference, with the second shaft circumference being less than the first shaft circumference. The hosel assembly is sized and configured to mate with the distal end 34 of the shaft 20, as shown in FIG. 12, and as described below.
  • The clubhead assembly 30 includes a hosel 12, a clubhead 38 (such as the putter head 10 discussed above), and an attachment means 40. As shown in FIGS. 11-12 the hosel 12 includes a shaft receiving recess 22 and a hub portion 42. The shaft receiving recess 22 is sized and configured to receive the distal end 34 of the shaft 20 therein. As is known in the art, various adhesives may be used in forming a strong bond between the shaft receiving recess 22 and the distal end 34 of the shaft 20. Nevertheless, according to an aspect of the present invention, it is contemplated that the shaft 20 also may be integrally formed with the hosel 12. Referring again to FIG. 11, the hub portion 42 of the hosel 12 defines a first face 44, a guide face 46, and a rotation axis 48. The first face 44 is preferably planar and may be oriented relatively orthogonally with respect to the rotation axis 48. In this regard, as will be explained further below, although it is preferred to have a planar first face 44, the first face 44 need only be configured to mate with another surface. Therefore, the first face 44 may be configured as any two or three dimensional surface. The guide face 46 is opposite the first face 44 and may also be configured as a two or three dimensional surface. As discussed above, the hosel 12 may also include at least one guide selection marking 16, which is preferably disposed on the guide face 46 of the hub portion 42, as shown in FIG. 12. Finally, the hub portion 42 is also be formed to include a first engagement element 50 being disposed on the first face 44.
  • With reference to the clubhead 38, the clubhead 38 defines front and rear sections 52, 54. The clubhead 38 may also be fabricated of a variety of materials in order to provide the desired mechanical properties as are necessary in golf. As is known in the art, the front section 52 of the clubhead 38 includes a forward face 56 that is configured to strike a golf ball, and may include various design features as are known in the art. For example, the forward face 56 may be planar. In addition, the clubhead 38 may also define a clubhead axis 58 that extends longitudinally through the clubhead 38. Thus, in one implementation, the clubhead axis 58 extends parallel to the plane of the forward face 56.
  • According to another aspect of the present invention, the rear section 54 of the clubhead 38 includes a hub receptor 60. The rear section 54 may be defined as that portion of the clubhead 38 opposing the forward face 56 of the front section 52. Thus, as shown in FIG. 11, the clubhead 38 may be formed in a variety of shapes, such as a putter, a nine-iron, or a driver, just to name a few. The rear section 54 may thus occupy a majority of the clubhead 38. In this regard, the hub receptor 60 may also occupy any position in the rear section 54 of the clubhead 38. In preferred embodiments however, the hub receptor 60 is centrally disposed in the rear section 54, as illustrated in FIG. 11.
  • In an implementation of the present invention, the hub receptor 60 defines a second face 62 and includes a second engagement element 64 that is disposed on the second face 62. The hub receptor 60 is rotatably engageable to the hub portion 42 of the hosel 12. The relative rotation of the hub receptor 60 about the hosel 12 occurs about the rotation axis 48 with the first face 44 mating with the second face 62. As described further below, the first engagement element 50 is matable with the second engagement element 64 for impeding rotational movement of the hosel 12 with respect to the clubhead 38 at a clubhead angle 66.
  • The configuration of the clubhead 38, including the position and configuration of the hub receptor 60, may be determined in response to design requirements aimed at achieving a properly weighted or properly responsive clubhead 38, as may be performed by one of skill in the art. Other considerations, such as the angular orientation of the forward face 56 of the clubhead 38, the density of the clubhead 38, the materials from which the clubhead 38 is fabricated, and the size and configuration of the clubhead 38 may be variously modified by one of skill in the art. It is contemplated that by modifying such variables, the teachings herein may be used to provide clubhead assemblies 30 that may be used in a wide variety of golfing applications. For example, the clubhead 38 may be the putter head 10 discussed above; however, the clubhead 38 may be modified to be any driver, iron, wood, or other type of golfing implement known in the art.
  • As illustrated in FIGS. 11-12, the hub portion 42 of the hosel 12 is configured to engage the hub receptor 60 of the clubhead 38. Both the hub portion 42 and the hub receptor 60 should preferably be complimentarily formed in order to facilitate proper engagement. In one embodiment, shown in FIGS. 11-12, the hub portion 42 is preferably configured to be cylindrical. Thus, the hub receptor 60 may be formed as a cylindrical concave recess portion whereinto the cylindrical hub portion 42 is received. In this regard, the concave recess portion may be defined by a raised socket wall 68. However, it is also contemplated that the hub receptor 60 includes no raised portion whatsoever. Nevertheless, the raised socket wall 38 may encircle the hub portion 42 of the hosel 12 by extending about a periphery 70 of the hub portion 42. However, the raised socket wall 68 may extend only about a majority of the periphery 70 of the hub portion and define a gate 72, as shown in FIG. 11. In such an embodiment, the gate 72 may be sized and configured to provide for passage and rotational movement of the hosel 12. Thus, the hosel 12 may include a central section 74 that extends between the hub portion 42 and the shaft receiving recess 22. The central section 74 may be substantially coplanar with the hub portion 42, for example, by joining with the hub portion 42 at a position intermediate the guide face 46 and first face 44 of the hub portion 42, as shown in FIG. 11. In such a case, the raised socket wall 68 should preferably include the gate 72 to facilitate rotational movement of the hosel 12 with respect to the clubhead 38. However, the central section 74 may also extend toward the hub portion 42, joining with the hub portion 42 at the guide face 46 of the hub portion 42. In this latter implementation, the raised socket wall 68 need not include the gate 72.
  • As mentioned above, the raised socket wall 68 may surround the majority of the periphery 70 of the hub portion 42. In such an innovative embodiment, shown in FIGS. 11-12, the hub portion 42 would have only two degrees of freedom: rotational movement about the rotation axis 48 and axial movement along the rotation axis 48. Each of these movements is innovatively controlled as discussed herein. First, because the hub portion 42 may be received to within the hub receptor 60 with the raised socket walls 68 surrounding the majority of the periphery 70 of the hub portion 42, extrication of the hub portion 42 from the hub receptor 60 due to centrifugal forces along the shaft axis 36 would be prevented. Therefore, in use, the clubhead 38 may tend to be securely mounted to the hosel 12, thus improving the safety of the assembly 30. Further, it is noted that by providing that the raised socket walls 68 surround a majority of the periphery 70 of the hub portion 42, as shown in FIG. 11, the only ready method of inserting or removing the hub portion 42 from the hub receptor 60 is through translational movement along the rotation axis 48. This translational movement along the rotation axis 48 is preferably restricted by the attachment means 40. Therefore, if the raised socket wall 68 is closely fitted with the hub portion 42, it is contemplated that the raised socket wall 68 may bear a majority of the centrifugal forces that are present between the hub portion 42 and the hub receptor 60 during a swing of the golf club 32. Thus, such centrifugal forces may be shared between the hub receptor 60 and the attachment means 40. Such a design advantage allows for an improved dispersion of centrifugal and axial forces, and may tend to ensure that the engagement between the hosel 12 and the clubhead 38 does not fail during the swing of the golf club 32.
  • As discussed above, the first face 44 of the hub portion 42 mates with the second face 62 of the hub receptor 60. As illustrated in FIG. 11, the first and second faces 44, 62 may preferably be configured to be substantially planar. Nevertheless, the first and second faces 44, 62 may be formed as any three dimensional geometric surface. Importantly, the first and second faces 44, 62 should be configured to substantially mate, which may include that the first face 44 contacts the second face 62 along a majority of the surface thereof. Thus, if the first face 44 is concave, the second face 62 should preferably be shaped as a substantially convex surface so as to facilitate proper mating between the first face 44 and the second face 62. The mating relationship may thus provide that the first face 44 substantially mirrors the second face 62.
  • The mating relationship of the first and second faces 44, 62 also preferably includes that the first engagement element 50 corresponds to the second engagement element 64 to provide necessary frictional or locking engagement to impede the relative rotation of the hub receptor 60 about the hosel 12. In this regard, as illustrated in FIG. 11, the first engagement element 50 may be formed to include at least one tooth projection, and the second engagement element 64 may include at least one corresponding notch. Indeed, the configuration of the first and second engagement elements 50, 64 may be variously modified according to the teachings herein. For example, both of the first and second engagement elements 50, 64 may include at least one tooth projection and at least one notch. Additionally, the first and second engagement elements 50, 64 may include a series of radial serrations, such as a radial serration profile shown in FIG. 11. Nevertheless, the first and second engagement elements 50, 64 may include any number of teeth, bumps, ribs, notches, pins, or recesses to provide the necessary frictional or locking engagement to impede the relative rotation of the hub receptor 60 about the hosel 12. Thus, the user may select a preferred clubhead angle 66 and engage the first engagement element 50 with the second engagement element 64 in order to fix the orientation of the hosel 12 with respect to the clubhead 38. In this regard, the clubhead angle 66 is defined as the orientation of the shaft axis 36 with respect to the clubhead axis 58.
  • As illustrated in FIG. 12, the attachment means 40 may include a screw 14 that is insertable through a screw hole 76 of the hub portion 42 of the hosel 12 and fastenable to a threaded hole 78 in the hub receptor 60 of the clubhead 38. Such configuration may provide for simplicity of use, thus allowing the user to simply loosen the screw 14, disengage the first engagement element 50 from the second engagement element 64, and rotate the hub portion 42 with respect to the hub receptor 60 to a desired clubhead angle 66. Then, the user may simply tighten the screw 14 which would cause the first engagement element 50 to mate with the second engagement element 64 and thereby fix the orientation of the hosel 12 with respect to the clubhead 38 at the desired clubhead angle 66.
  • The attachment means 40 facilitates the mating of the first engagement element 50 with the second engagement element 64, which is accomplished by press-fitting the first face 44 to the second face 62. Thus, other attachment means 40 which perform such a press-fitting, may be utilized. For example, the hub receptor 60 may be configured to include a biasing element, such as a spring, which contacts the hub portion 42 of the hosel 12 and urges the first face 44 against the second face 62. Appropriate structure may be included in the rear section 54 of the clubhead 38 in order to anchor and/or support the biasing element. Thus, the biasing element may allow the first face 44 of the hosel 12 to be in fixed contact with the second face 62 of the clubhead 38 with the first and second engagement elements 50, 64 being mated, thus securing the orientation of the hosel 12 with respect to the clubhead 38 at a desired angle.
  • Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the claims.
