Problems solved by technology

One defect in this design, however, is that with the normal follow through of a driving stroke the trough is oriented at a very significant angle relative to the path of travel of the club head through the air.
This actually increases the turbulence of the air in the wake of the club head passing through the air.
As a consequence, an inordinate amount of the power of the stroke is expended in disturbing the air through which the club passes.

Embodiment Construction

[0022] FIG. 1 illustrates a PD 901 titanium golf club head 10 mounted upon the lower extremity of a golf club shaft 12 of a golf driver. The golf club head 10 has a substantially planar ball-impact face 14, a convex top surface 16, a convex sole 18 illustrated in FIG. 5, a back 20 located opposite the ball-impact face 14, a heel 22, and a toe 24. The golf club head 10 also has a hozzle 26 located at the top of the heel 22 at the junction between the heel 22 and the top surface 16. As in conventional golf clubs, the hozzle 26 defines a tubular opening therewithin to receive the cylindrical attachment tip of the golf club shaft 12.

[0023] The golf club head 10 is preferably formed of aluminum and titanium and is fabricated as a two-part hollow casting. The general overall size and shape of the golf club head 10 is fairly conventional. The sole is about 7.5 centimeters in width as measured between the ball-impact face 14 and the back 20 at the transition between the sole 18 and the back...

Abstract

The head of a golf club is improved by reducing the drag and wake turbulence produced in the air when the golf club is swung to strike a golf ball. The club head has a convex sole with an elongated depression defined therein. The inboard end of the depression is located proximate both the heel and the ball-impact face and extends outwardly at a diverging angle from the ball-impact face to an outboard extremity located inboard from the toe of the club head. This depression or channel is thereby closely aligned with the direction of travel of the club head during a normal downswing and follow through of a golf stroke. Also, the top of the club head is covered with a relatively rough coating, such as a textured paint with granules encapsulated therein. The roughness average of the top surface of the club head, as measured by a profilometer, is it least three times as great as that of the ball-impact face and at least three times as great as that of the sole of the club head.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to an improved construction for a golf club head. The invention has particular applicability to the types of golf clubs used to drive golf balls long distances, such as a driver.[0003] 2. Description of the Prior Art[0004] A wide variety of golf club head configurations have been devised over the years in efforts to aid golfers in enhancing their proficiency in playing the game of golf. While golf club heads have been manufactured in many different shapes, virtually all golf club heads have the same basic parts. Specifically, a golf club head is comprised of a ball impact face, a sole, a top, a heel, a toe, and a back[0005] Also, golf club heads designed for use on clubs for shots of prescribed distances have certain similarities to each other. For example, the heads of golf club drivers and mashies are relatively massive. These club heads typically have a width of between about five and ten centimeters as measured...
