Brief Patent Description - Full Patent Description - Patent Application Claims
FIELD OF THE INVENTION [0001] This invention relates to a method of manufacturing sports equipment, specifically a three or four piece golf club head. DISCUSSION OF RELATED ART [0002] The traditional forged component structure of a golf-club head has four pieces, a crown, a hosel, a sole and a faceplate FIG. 4. The crown of the traditional four-piece crown is welded to the skirt so that leakage of solder wire is about 8-10 g, which concentrates on the upper part of the head, raising the head's center of gravity. The total solder welding weight is about 22 g which can affect the golf club head weight distribution and center of gravity. This causes loss of precision and other center of weight problems that have long been unsolved in four-piece type of golf-club head. The weight distribution of a club head is generally uniform. A popular method of correcting the center of gravity is to add inserts commonly made of heavier material to the sole and skirt of the head. [0003] Traditionally, the sole and skirt are integrally formed from one sheet of metal as seen in FIG. 5. It preferred to have a thicker sole than the skirt. Unfortunately, the traditional method makes this difficult because the sole and skirt are formed from a uniform thickness planar metal sheet. Additionally, the hosel connection requires excessive solder accumulation causing a variety of weight distribution and tolerance problems. BRIEF DESCRIPTION OF THE DRAWINGS [0004] FIG. 1 is a front exploded view of the club head. [0005] FIG. 2 is a front assembled view of the club head. [0006] FIG. 3 is a side section view of the club head. [0007] FIG. 4 is a side section view of the prior art club head. [0008] FIG. 5 is a side exploded view of the prior art club head. [0009] FIG. 6 is a side assembled view of the prior art club head. [0010] FIG. 7 is a side exploded view of the club head. [0011] FIG. 8 is a side assembled view of the club head. [0012] FIG. 9 is a side view of the crown. [0013] FIG. 10 is a side view of the prior art crown. OBJECTS OF THE INVENTION [0014] 1. Relocating welding seams to the bottom, and avoiding skirt to crown welding. Lowering the sweet spot by 1-1.5 mm. [0015] 2. Making a design where welding solder does not change the center of gravity as much. Save 8 grams of welding weight and have only about 14 grams of welding concentrated in the lower sole plate. [0016] 3. Using the welding solder weight savings to lower the center of gravity by having a thicker sole plate. [0017] 4. Creating a better hosel connection by having a one-piece stretch formed hosel connection to allow tighter tolerance. BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENT [0018] This application is a Continuation in Part of U.S. patent application Song, Ser. No. 11/031,058 SPD Club Head. A mold may use a wide variety of metal forming methods such as forging, casting, stamping, rolling, or super plastic deformation to make the parts to the golf-club head. One method in current use is discussed in Song, U.S. patent Ser. No. 10/672,463, which is incorporated herein by reference. Here a wide variety of means for forming parts can be used. Although a wide variety of means for forming parts can be used, it is preferred to make the sole from super plastic deformation technique. The super plastic deformation technique is not required for any part of the invention. Also, titanium is not required, but preferred as the best mode. [0019] The key to this invention is the crown 110 with skirt and stretched hosel connection. A mold draws the crown FIG. 1, 110 of the golf-club head to integrally include a skirt and stretched hosel connection 117. Thus, the crown is formed from a flat sheet of metal. In certain crown shapes, the male mold member may have to be made collapsible. According to the prior art it is well known how to make a male mold member collapsible for removal from the workpiece.
