Golf club and set of golf clubs

A set of golf clubs including a golf club comprising a head and a shaft, wherein the head has an extension and the shaft is joined to the extension and extends therefrom at a shaft tip, the shaft tip having a diameter of 0.370-0.4 inch and the head is approximately 220 cc or greater.

BACKGROUND OF THE INVENTION 
Large head golf clubs have been sold and used for many years and large 
diameter shafts, i.e., shafts over 0.370 inches have been proposed (U.S. 
Pat. Nos. 5,093,162 and 4,132,579). 
SUMMARY OF THE INVENTION 
Broadly, the present invention is a combination of a supersize golf club 
head having a shaft with a large diameter tip shaft. More particularly, 
the invention is directed to the combination of wood club head (preferably 
a metal wood) having a volume greater than 225 c and a shaft attached 
thereto having a tip diameter greater than 0.370 inches. 
The invention is also directed to a club with a head having between 8 and 
12 degrees of loft and a volume greater than 225 c and a shaft having a 
tip diameter greater than 0.370 inches; a club with a head having 
approximately 14 degrees of loft and a volume of approximately 220 c and a 
shaft with a tip diameter greater than 0.370 inches; a club with a head 
having approximately 18 degrees of loft and a volume of approximately 190 
c and a shaft having a tip diameter greater than 0.370 inches; a club with 
a head having approximately 21 degrees of loft and a volume of 
approximately 160 c and a shaft having a tip diameter greater than 0.370 
inches; and the combination thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to the Figures, club 8 includes head 9 and shaft 10. Head 9 
includes head extension 11 with a portion of shaft 10 inserted into 
extension 11 (which portion is not shown) and the head includes face 12. 
The attachment of the shaft 10 to the extension 11 forms a plane of 
joinder P where the shaft emerges from the extension. Shaft 10 has a tip 
diameter (TD) measured at the plane of joinder P where shaft 10 emerges 
from extension 11. Head face 12 defines a plane from which the club loft 
can be defined and includes horizontal dimension d.sub.1 and vertical 
dimension d.sub.2. The area of face 11 is computable using these 
dimensions and other similar dimensions. 
Turning to FIGS. 2 and 3, alternative club 16 includes a head 17 and a head 
extension 18. Also shown are grip 21, shaft 23, shaft diameters D1, D2 and 
TD. Diameter TD is less than Diameter D2 which is less than diameter D1. 
The shaft tip diameter (TD) is measured at plane of joinder, i.e., where 
the shaft 23 emerges from the uppermost point (UP) of extension 18. D2 and 
D1 are diameters of the shaft and, more particularly, are diameters in the 
tapered section of the shaft. 
The size of wood heads including metal wood heads is measured by the volume 
such head (including the head extension) displaces when placed in water or 
other liquid. Heads are classified as standard, midsize, oversize and so 
forth. The present invention is directed to supersize heads which are 
heads with volumes of 225 c and greater. Preferably, the club head of the 
present invention has a volume between 225 c and 275 c and, most 
preferably, the club head has a volume of approximately 250 c. 
Furthermore, the club head is made of a light weight metal and, most 
preferably, the club head is made from a titanium alloy such as TI64 
alloy. 
The preferred club head has a volume of greater than 225 c and a loft 
between approximately 8 and 12 degrees. The loft is the angle of the club 
face plane 12 relative to the vertical plane (not shown). As shown in FIG. 
2a, another embodiment of the present invention is a club 9a with a head 
having a volume of approximately 220 c, a loft L1 of approximately 14 
degrees and shaft tip diameter of approximately 0.390 inches. As shown in 
FIG. 2b, still another embodiment of the present invention is a club 9b 
with a head having a volume of approximately 190 c, a loft L2 of 
approximately 18 degrees and a shaft tip diameter of approximately 0.390 
inches. As shown in FIG. 2c yet still another embodiment of the present 
invention is a club 9c with a head having a volume of approximately 160 c, 
a loft L3 of approximately 21 degrees and a shaft tip diameter of 
approximately O.390 inches. 
Shaft tip diameter (TD) is measured at the plane where the shaft emerges 
from the head extension. A large shaft tip diameter is a diameter of 0.370 
inch or larger. Preferably the shaft tip is in the range of 0.380 to 0.400 
inches and, most preferably, the shaft tip is approximately 0.390 inches. 
The preferred shaft can be of a tapered tip shaft construction as disclosed 
in U.S. Pat. No. 4,132,579 or of a constant tip diameter construction as 
disclosed in U.S. Pat. Nos. 5,093,162 and 4,757,997, which are all 
disclosed herein by reference. Preferably, the shaft is constructed 
exclusively of multiple plies that incorporate standard modulus graphite 
fibers (tensile modulus of approximately 30-38 million psi). 
Wherein it is apparent that the invention herein disclosed from the various 
embodiments will provide many improvements, it will be appreciated that 
numerous modifications and other embodiments may be made by those of 
ordinary skill in the art and it is intended that the appended claims 
cover such modifications and embodiments that fall within the spirit and 
scope of the present invention.
