CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application is based upon U.S. Provisional Patent Application Ser. No. 60/610,199, entitled "GOLF CLUB HEAD WITH A WEIGHTING SYSTEM", filed Sep. 16, 2004.

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The invention relates to a golf club head employing a removable weighting system.

[0004] 2. Description of the Prior Art

[0005] Over the past twenty years, metal wood type golf club heads have replaced solid wood club heads. The metal wood type golf club heads offer the opportunity to enhance the striking characteristics of the club head by shifting the weight distribution within the club head, altering the materials from which the metal wood type golf club head is manufactured and increasing the overall size and "sweet spot" of the club head without substantially increasing the weight of the club head.

[0006] Current oversized driver heads commonly exceed 300 cc in volume and are conventionally manufactured from lightweight alloys, for example, titanium alloys. In an effort to enhance the striking characteristics of these relatively large club heads, weights are often added at various internal and external locations along the club head to improve, based upon personal preferences of a golfer, the launch angle and flight trajectory of a golf ball. The weight members are commonly manufactured from high-density materials.

[0007] However, mass produced clubs are manufactured with a weight distribution chosen to assist a large range of golfers. The weight distribution of a mass produced golf club may, therefore, be too heavy or too light. In addition, the weight distribution may be positioned too far toward the striking face, too far toward the rear of the club head, too far toward the toe of the club head or too far toward the heel of the club head to suit individual golfers.

[0008] As such, a need exists for a golf club head that allows a golfer to fine tune the weight of the club head for his or her swing. Attempts have been made in the prior art to achieve such a goal. However, none of these prior attempts have been successful in providing a reliable weighting system that is not adversely affected by use of the club head, for example, by vibrations imparted to the club head during use. The present invention provides a golf club offering a selectively removable weighting system that provides for reliable and secure attachment of a plurality of weight members to a club head such that a golfer may readily customize his or her golf clubs to enhance performance by specifically tuning the golf club head for producing a desired launch angle and/or flight trajectory.

SUMMARY OF THE INVENTION

[0009] It is, therefore, an object of the present invention to provide a golf club head including a club head body having a plurality of recesses and a plurality of weight members shaped and dimensioned for selective placement within the recesses.

[0010] It is also an object of the present invention to provide a golf club head wherein the club head is a metal wood type club head and the club head body is substantially hollow.

[0011] It is another object of the present invention to provide a golf club head wherein the club head body includes a sole, a crown, a toe, a heel and a hosel, and the recesses are formed in the sole.

[0012] It is a further object of the present invention to provide a golf club head wherein the club head body includes four recesses positioned about the club head body.

[0013] It is also another object of the present invention to provide a golf club head wherein the club head body has a volume of approximately 460 cc and the plurality of weight members have a total mass of approximately 24 g.

[0014] It is also a further object of the present invention to provide a golf club head including sleeves positioned within the recesses.

[0015] It is still another object of the present invention to provide a golf club head wherein the sleeves are adhesively secured within the recesses.

[0016] It is also an object of the present invention to provide a golf club head wherein the sleeves are composed of aluminum.

[0017] It is yet a further object of the present invention to provide a golf club head wherein each sleeve has a mass of less than approximately 10 g.

[0018] It is also another object of the present invention to provide a golf club head wherein each sleeve has a mass of less than approximately 5 g.

[0019] It is still another object of the present invention to provide a golf club head wherein each sleeve includes a coupling member for selectively securing weight members thereto.

[0020] It is a further object of the present invention to provide a golf club head wherein each sleeve includes internal threading shaped and dimensioned to receive threading of the weight member.

[0021] It is also an object of the present invention to provide a golf club head wherein threading of the sleeves and weight members includes a wedge ramp.
