Benefits of technology
The present invention provides a golf club head with heel and toe weights attached in a beneficial way. The method involves inserting the body of the club head into a cavity in a weight, with the weight rotated to interlock with the body. This results in a secure attachment of the weights to the club head, which improves the accuracy and consistency of the club's performance.
Problems solved by technology
The use of perimeter weighting can lead to a number of manufacturing problems, however.
For example, it is often difficult to join the perimeter weights to the club head body such that the weights are securely attached to the body.
Furthermore, in cases where variable or customization of weighting is desired, known perimeter weighting techniques make it difficult or impossible to change weighting schemes.
This is particularly the case where the perimeter weights and club head body are fabricated using different materials which may not be amenable to the same processing techniques and whose different mechanical characteristics make them difficult to join in a robust manner.

Embodiment Construction
[0011]FIG. 1 illustrates an end portion (e.g., a heel end or a toe end) of a golf club head 100, preferably a putter head, including an interlocking body 102 and a weight 104 in accordance with one embodiment of the present invention. As shown, body 102 includes a boss 106 generally configured to interlock with a corresponding cavity 108 within weight (or “ballast”) 104. More particularly, boss 106 includes two generally arcuate surfaces 110 and 112 which mate with corresponding arcuate surfaces 120 and 122 within cavity 108 of weight 104, while two generally planar surfaces 116 and 114 on opposite sides of boss 106 mate with corresponding planar surfaces 126 and 124 of cavity 108. Hence, it is preferred that the radius of curvature of surfaces 110, 112, 108, and 122 are substantially identical (and their centers of rotation coincident) to facilitate the rotation of weight 104 as boss 106 seats within cavity 108. As is known in the art, an exemplary golf putter club head typically i...

A method of forming a golf club head includes providing a body having an end portion (e.g., a heel end or a toe end of the club head) wherein the body end portion includes a lower surface and a boss extending therefrom. The method comprises providing a weight having a top surface and a cavity configured to receive the boss, and inserting the boss on the body into the cavity in the weight by rotating the weight such that the boss interlocks with the cavity and so that at least a portion of the top surface of the weight contacts at least a portion of the lower surface of the body end portion. The weight further includes a protrusion having a concave surface and the body has a corresponding convex surface. The weight is rotated about an axis extending through the body such that the concave surface of the weight bears on the convex surface of the body
Description
BACKGROUND OF THE INVENTION [0001] This invention relates generally to golf clubs and, in particular, to a method for fabricating a golf club head having heel and toe weights. [0002] It is often desirable to incorporate heel and toe weighting into a club head body to increase the moment of inertia of the club. This increased moment of inertia tends to decrease club head twisting in the event the golfer strikes the golf ball off-center. In an effort to increase the moment of inertia, some prior art club heads utilize a low-density material for the club head body in conjunction with a higher density material for the heel and toe weights. [0003] The use of perimeter weighting can lead to a number of manufacturing problems, however. For example, it is often difficult to join the perimeter weights to the club head body such that the weights are securely attached to the body. [0004] Furthermore, in cases where variable or customization of weighting is desired, known perimeter weighting te...
