Golf club head

Golf club head description/claims

This application is a continuation-in-part of U.S. patent application Ser. No. 11/509,706, entitled “GOLF CLUB HEAD AND GOLF CLUB SHAFT”, filed Aug. 25, 2006, which is currently pending, which claims the benefit of U.S. Provisional Patent Application Ser. No. 60/710,875, entitled “GOLF CLUB HEAD”, filed Aug. 25, 2005.

1. Field of the Invention

This invention relates to a golf club head. More particularly, the invention relates to a golf club head composed of a transparent, lightweight material offering enhanced mass positioning within a golf club head. The invention also relates to a golf club shaft offering improved performance and functionality.

2. Description of the Prior Art

Golf club manufacturers are consistently attempting to design golf clubs that are easier to hit and offer golfers greater forgiveness when the ball is not struck directly upon the sweet spot of the striking face. As those skilled in the art will certainly appreciate, many designs have been developed and proposed for assisting golfers in learning and mastering the very difficult game of golf.

Much of the focus of the golf club heads is on ways to shift the weight within the golf club head in a manner which improves the striking characteristics of the club. As such, a need exists for an improved golf club head which provides for greater versatility in shifting mass about a golf club head in a manner improving the striking characteristics of the golf club head.

It is, therefore, an object of the present invention to provide a metal wood type golf club head including a club head body having a striking face with a loft of approximately 7 degrees to approximately 13 degrees, a soleplate, a crown, a toe, a heel and a hosel. The club head body has a volume greater than 300 cc and a mass of approximately 180 g to approximately 250 g. The club head body includes a body shell composed of the striking face, soleplate, crown, toe and heel. The body shell has a mass of no more than approximately 150 g, wherein at least a portion of the body shell is composed of a carbon nanotube sheet comprising a yarn of carbon nanotubes.

It is also an object of the present invention to provide a metal wood type golf club head wherein the yarn is composed of single wall carbon nanotubes.

It is another object of the present invention to provide a metal wood type golf club head wherein the yarn is composed of multi-wall carbon nanotubes.

It is a further object of the present invention to provide a metal wood type golf club head wherein the yarn consists essentially of carbon nanotubes.

It is also an object of the present invention to provide a metal wood type golf club head wherein the yarn includes carbon nanotubes and steel thread.

It is another object of the present invention to provide a metal wood type golf club head wherein the carbon nanotube sheet has a density of less than approximately 2.5 g/cm3 and tensile strength of at least approximately 465 MPa/(g/cm3).

It is a further object of the present invention to provide a metal wood type golf club head wherein the striking face is composed of a carbon nanotube sheet.

It is also an object of the present invention to provide a metal wood type golf club head wherein the crown is composed of a carbon nanotube sheet.

It is another object of the present invention to provide a metal wood type golf club head wherein the soleplate is composed of a carbon nanotube sheet.

It is a further object of the present invention to provide a metal wood type golf club head including a club head body having a striking face with a loft of approximately 13 degrees to approximately 24 degrees, a soleplate, a crown, a toe, a heel and a hosel. The club head body has a volume of approximately 100 cc to 250 cc and a mass of approximately 205 g to approximately 245 g. The club head body includes a body shell composed of the striking face, soleplate, crown, toe and heel. The body shell has a mass of no more than 150 g, wherein at least a portion of the body shell is composed of a carbon nanotube sheet comprising yarn of carbon nanotubes.

It is also an object of the present invention to provide a hybrid type golf club head including a club head body having a striking face, a soleplate, a crown, a toe, a heel and a hosel. The club head body has a volume of approximately 70 cc to 150 cc and a mass of approximately 210 g to approximately 260 g. The club head body includes a body shell composed of the striking face, soleplate, crown, toe and heel. The body shell has a mass of no more than 150 g, wherein at least a portion of the body shell is composed of a carbon nanotube sheet comprising yarn of carbon nanotubes.

It is another object of the present invention to provide a hybrid type golf club head wherein the yarn is composed of single wall carbon nanotubes.
