AI Technical Summary

Benefits of technology

[0013] The invention also addresses the desire for the driver to have a normal appearance. The invention achieves both criteria by reducing the distance from front to back as compared to the conventional design, which has a head depth to face depth ratio of about 1.8 to 2.
[0015] Although the CG is not as far back from the clubface because of its narrower depth design, the advantage of a much bigger clubface and high loft gives the less skillful golfer the highest probability of hitting the golf ball well.
[0016] The driver of the present invention is believed to be the first oversize titanium driver over 400 cc to have at least 17 degrees of loft. Compared to other drivers that typically have 8 to 12 degrees of loft, 17 degrees of loft is equivalent to the loft of a 4 wood, which makes it very easy for the unskillful golfer to launch the ball higher. The ball may not travel far as compared to a shot hit by an intermediate to advanced golfer, but it becomes airborne and travels a reasonable distance to give the unskillful golfer confidence in his or her ability to hit the golf ball with some regularity.

Problems solved by technology

This group of golfers lacks the skill and the speed to hit a conventional driver well.
The problem with making a driver with that big a face is the volume.
Although it would then look like a conventional shape driver just proportionally bigger, it would look very clumsy when the club length is not proportionally longer.

Embodiment Construction

[0026] Referring to the accompanying drawings, it will be seen that a golf club driver 10 comprises a driver head 12 having hosel 14 and being affixed to a shaft 16 terminating in a grip end 18. Head 12 has a very large face or hitting surface 20, a crown 22, a toe 24, a heel 26, a sole 28 and a rear surface 30. Face 20 preferably has a pattern of score lines 25 as is well known in the art of golf clubs. The preferred head shape may be readily discerned from FIGS. 2-7 which show head 12 from all six standard directions including face-end view (FIG. 2), rear-end view (FIG. 3), crown view (FIG. 4), sole view (FIG. 5), toe view (FIG. 6) and heel view (FIG. 7).

[0027] In the preferred embodiment shown herein, the face is about 2⅝ inches deep (“X” in FIG. 6) and about 3% inches wide at the sweet spot. The total volume of the head 12 is over 400 cc. The club head depth is about 3⅛ inches (“Y” in FIG. 5). The ratio of club head depth “Y” to club face depth “X” is about 1.2. As described ab...

Abstract

An oversize golf club driver head has the maximum legal face dimensions, a loft of at least 17 degrees and a ratio of club depth to face depth that is less than 1.5. This unconventional combination of driver parameters is designed to make it easier for beginning golfers and less skilled golfers to reliably hit a golf ball from a golf tee and thereby give such golfers more confidence in their ability to hit a golf driver. Nevertheless, it results in a golf club driver head configuration which complies with USGA rules and is not peculiar in appearance.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates generally to golf club heads and more specifically to a golf club driver head which is designed for use by less skilled golfers. [0003] 2. Background Art [0004] Most manufacturers offer a big titanium driver. However, most want to abide by the rules set by USGA regarding the size limit of a driver. The volume limit for drivers is currently 460 cc. Therefore, there is a limitation as to how big the driver can be. The biggest club head on the market to date is a 650 cc driver, but it does not conform to USGA rules. There is also a limitation as to how deep the driver can be, which is 2.8 inches from the top of crown to the sole. This makes the maximum clubface depth about 2.6 (65 mm) inches taking the curve of the crown plate into consideration. The width is also limited to 5 inches from heel to toe. [0005] No manufacturer has been able to achieve this maximum face size without exceeding ...
