  • DETAILED DESCRIPTION OF THE INVENTION
  • As shown in FIGS. 1-4, a golf club head is generally designated 20. The golf club head 20 preferably includes a body 22 having a crown section 36, a sole section 38 with a protrusion 60, a heel end 24, a toe end 26 and an aft end 28. A face component 30 is placed over an opening 39 in the body 22. The body section 22, along with the face component 30, preferably defines a hollow interior 40. Within the hollow interior, multiple carbon tubes 50 extend from the protrusion 60 of the sole section 38 upward to the crown section 36.
  • The plurality of carbon tubes 50 preferably ranges from two carbon tubes to eight carbon tubes. Each of the plurality of carbon tubes 50 preferably has a diameter ranging from 2 millimeters to 5 millimeters. Each of the plurality of carbon tubes 50 preferably has a length ranging from 30 millimeters to 60 millimeters. Each of the plurality of carbon tubes 50 is preferably positioned within 11 millimeters of an interior surface of the face section 30. The mass of each of the plurality of carbon tubes 50 preferably ranges from 0.5 gram to 3 grams, more preferably from 1 gram to 2 grams, and most preferably each carbon tube 50 has a mass of 1.5 grams.
  • The crown section 36 preferably comprises a plurality of apertures 42. Each of the plurality of apertures 42 preferably corresponds to a carbon tube 50 of the plurality carbon tubes 50. The sole section 38 preferably comprises a plurality of bosses 43. Each of the plurality of bosses 43 preferably corresponds to a carbon tube 50 of the plurality of carbon tubes 50. The carbon tubes 50 are preferably glued into the bosses 50.
  • The face component 30 preferably comprises a striking plate section 30 a and return sections 31 a and 31 b that are substantially perpendicular to the striking plate section 30 a. The face component 30 is preferably welded over the opening 39 of the body 22. The face component 30 is preferably composed of a metal that is different than the metal of the body 22. The face component 30 is preferably composed of a high performance metal material such as SP700 titanium alloy, carpenter steel, or the like. The face component 30 preferably has a varying thickness. In a preferred embodiment, the face component 30 has a varying thickness such as described in U.S. Pat. No. 7,448,960, for a Golf Club Head With Variable Face Thickness, which pertinent parts are hereby incorporated by reference. Other alternative embodiments of the thickness of the face section 30 are disclosed in U.S. Pat. No. 6,398,666, for a Golf Club Striking Plate With Variable Thickness, U.S. Pat. No. 6,471,603, for a Contoured Golf Club Face and U.S. Pat. No. 6,368,234, for a Golf Club Striking Plate Having Elliptical Regions Of Thickness, all of which are owned by Callaway Golf Company and which pertinent parts are hereby incorporated by reference. Alternatively, the face section has a uniform thickness.
  • The body 22 is preferably cast from molten metal in a method such as the well-known lost-wax casting method. The metal for casting is preferably titanium or a titanium alloy such as 6-4 titanium alloy, alpha-beta titanium alloy or beta titanium alloy for forging, and 6-4 titanium for casting. Alternatively, the body 22 is composed of 17-4 steel alloy. Additional methods for manufacturing the body 22 include forming the body 22 from a flat sheet of metal, super-plastic forming the body from a flat sheet of metal, machining the body 22 from a solid block of metal, electrochemical milling the body 22 from a forged pre-form, casting the body using centrifugal casting, casting the body 22 using levitation casting, and like manufacturing methods.
  • The golf club head 20, when designed as a driver, preferably has a volume from 200 cubic centimeters to 600 cubic centimeters, more preferably from 300 cubic centimeters to 500 cubic centimeters, and most preferably from 420 cubic centimeters to 470 cubic centimeters, with a most preferred volume of 460 cubic centimeters. The volume of the golf club head 20 will also vary between fairway woods (preferably ranging from 3-woods to eleven woods) with smaller volumes than drivers.
  • The golf club head 20, when designed as a driver, preferably has a mass no more than 215 grams, and most preferably a mass of 180 to 215 grams. When the golf club head 20 is designed as a fairway wood, the golf club head preferably has a mass of 135 grams to 200 grams, and preferably from 140 grams to 165 grams.
  • A preferred embodiment of the golf club head 20 has a volume of 460 cubic centimeters with the Characteristic Time (CT) of the face close to, but not exceeding 257 microsecond (“μS”) limit set by the USGA.
  • In order to achieve a low, frontward CG without affecting a weld seam, the protrusion 60 is located inside the hollow interior 40 and proximate the opening 39. This construction avoids creating welding problems, but still allows for discretionary mass to be located mostly low and forward in the golf club head 20.
  • The protrusion 60 preferably has a base section 60 b and an extension section 60 a. The composite tubes 50 are positioned on the extension section 60 b of the protrusion 60.
  • The protrusion 60, which preferably is cast into the body 22 but may, in alternative embodiments, be welded or affixed mechanically to the body 22, extends upwards from the sole section 38 and protrudes from the opening of the body 22. When the golf club head 20 is assembled, the protrusion 60 extends towards the face component 30 without making contact with the striking face 30 a. The protrusion 60 preferably comprises at least 20% of the mass of the body 22, and more preferably 30% of the mass of the body 22. The protrusion 60 preferably ranges in mass from 30 grams to 60 grams.
