- 1. Field
- This disclosure generally relates to golf clubs, and, more particularly, to clubs having a metal head, commonly called “irons”.
- 2. Description of the Related Art
- Current regulations call for a maximum of 14 golf clubs to be used by a golfer during a round of golf. Typically, a set of golf clubs ranges from a putter through so-called “iron” clubs designed for various distances and degrees of loft to so called “wood” clubs, which are used for the longest distance shots. The putter, of course, is used for the final shots taken on or around a putting green.
- A significant fraction of golf shots are made from the region surrounding the putting green. In the area around the putting green, the desired shot distance may not allow the use of a full swing with any of the 14 traditional clubs. Hitting shots with a variety of partial-strength swings is difficult for both novice and expert golfers.

FIG. 3 is a back view of the head and lower portion of the shaft of a golf club. -
FIG. 4 is a side view of the head and shaft of a golf club. - Throughout this description, elements appearing in figures are assigned three-digit reference designators, where the most significant digit is the figure number and the two least significant digits are specific to the element. An element that is not described in conjunction with a figure may be presumed to have the same characteristics and function as a previously-described element having a reference designator with the same least significant digits.
- Referring now to
FIG. 1 , a golf club may include agolf club head 110 and ashaft 180 which is only partially shown inFIG. 1 . Thegolf club head 110 may include a relativelythick body 120 and a generallyplanar face 160. Thebody 120 may have an undersurface, commonly called the “sole”, including a generally flatground contact area 122, aforward portion 124, and atrailing portion 126. Theforward portion 124 may be slightly curved, rising at an approximately 8° angle from theground contact area 122 to a leadingedge 128 where theforward portion 124 meets theface 160. Thetrailing portion 126 may rise at a slight angle, approximately 2° or 3° between theground contact area 122 and the back of thebody 120. - The
club head 110 may be provided with ahosel 140 having an opening for receiving the lower end of theclub shaft 180. Thehosel 140 may be located on thebody 120 such that the hosel opening is located behind the plane of theface 160. Thehosel 140 may be located on thebody 120 substantially and directly behind theface 160. As shown inFIGS. 1, 2 and 3, for example, thehosel 140 is on the right-hand side of the head 110 (when viewed from the front) which means this would be made for a right-handed golfer. For a left-handed golfer, thehosel 140 would be on the opposite side from the showing in these figures. - As shown in
FIG. 1 , theface 160 has a loft angle of 48 degrees. Within this description, the loft angle is defined to be the angle of the face with respect to a line normal to theground contact area 122 of the sole, measured in degrees. Theground contact area 122 may be approximately horizontal when the club is held in a resting position. Thus the loft angle may be approximately the angle between the face and vertical when the club is held in a resting position. A 48-degree loft angle may be useful for shots taken in the immediate vicinity of a putting green. The loft angle between theface 160 and a line normal to theground contact area 122 may be between 10 degrees and approximately 70 degrees. Club heads having different loft angles will impart different loft to the ball when driving it from the fringe or the rough area surrounding the green. -
FIG. 2 shows a front view of agolf club 200, which may be thegolf club 100, having aclub head 210 and ashaft 280 which is only partially visible. Except for a hosel (not visible) to which theshaft 280 is attached, theclub head 210 may be symmetrical about a vertical mid-plane. Theclub head 210 may have aface 260, which may be provided with a plurality oftransverse grooves 265. The transverse grooves may be cut into theface 260 with selected depths and widths to help impart spin to a golf ball struck with theface 260. -
FIG. 3 shows a back view of anexemplary golf club 300, which may be thegolf club club head 310 and ashaft 380 which is only partially visible. Theclub head 310 may include abody 320. Theshaft 380 may be joined to theclub head 310 at ahosel 340 which may include an opening in thebody 320 to receive the end of theshaft 380. - At least one
insert 330 may be disposed in an opening in a back surface of thebody 320. In the example shown inFIG. 3 , there are twoinserts 330, each of which may have a cylindrical shape and may be disposed within two cylindrical openings drilled or otherwise formed in the back surface of thebody 320. Theclub head 310 may be formed of a first material having a first density or weight per unit volume. Theinserts 330 may be formed of a second material having a second density substantially higher than the first density. For example, thehead 310 may be formed from an Aluminum alloy, and the inserts may be formed from Tungsten or an alloy that is primarily Tungsten. - The size, number, and location of the inserts may cause the center of gravity of the
head 310 to be lower than the center of a golf ball to be struck with theclub head 310. The diameter of a normal golf ball is 1.68 inches. Thus the size, location, and number ofinserts 330 may be determined to cause the center of gravity of thehead 310 to be less than 0.84 from the plane of the sole. The inserts may be positioned near the back of the club head to increase the moment of inertia of the club head. -
FIG. 4 shows acomplete golf club 400 which may be thegolf club golf club 400 may include ashaft 480 joined to aclub head 410. Theshaft 480 may include afirst curve 482 near the end of the shaft where it is inserted into thehosel 440 and asecond curve 484 which is between thefirst curve 482 and the straight portion of theshaft 480. The end of the shaft remote from the club head may be finished with a grip which is not shown. Thefirst curve 482 may lie in first plane, and thesecond curve 484 may lie in a second plane different from the first plane different from the first plane. - The straight portion of the
shaft 480 may be sufficiently long such that thegolf club 400 may have anoverall length 490 in excess of 32 inches. The shape of the club head, the low center of gravity, and the long doubly-curved shaft may, in combination, allow the use of pendulum swing, similar to a putting stroke, when a golfer hits shots around the putting green. The twocurves shaft 480 may be structured to position a golfer's hands slightly ahead of the leading edge of the golf club when the club is resting in its natural position. It is important for the golfer to keep his hands at or ahead of the leading edge of the golf club when using a pendulum stroke technique. This action and motion promote accuracy and solid contact with the golf ball during the stroke. - Throughout this description, the embodiments and examples shown should be considered as exemplars, rather than limitations on the apparatus and procedures disclosed or claimed. Although many of the examples presented herein involve specific combinations of method acts or system elements, it should be understood that those acts and those elements may be combined in other ways to accomplish the same objectives. With regard to flowcharts, additional and fewer steps may be taken, and the steps as shown may be combined or further refined to achieve the methods described herein. Acts, elements and features discussed only in connection with one embodiment are not intended to be excluded from a similar role in other embodiments.
- For means-plus-function limitations recited in the claims, the means are not intended to be limited to the means disclosed herein for performing the recited function, but are intended to cover in scope any means, known now or later developed, for performing the recited function.
