This application claims the benefit of U.S. Provisional Application No. 60/678,662, filed May 6, 2005, which is incorporated by reference herein in its entirety.
BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates generally to golf clubs, and more particularly, to golf clubs and associated methods adapted for achieving an address position and an improved swing technique whereby a golfer is positioned throughout the swing to take advantage of his binocular vision.
2. Description of the Related Art
A significant portion of a golfer's score is attributable to putting and wedge play around the green. Indeed, putting alone can account for more than 40% of an average round of golf. In this regard, golfers are endlessly working to optimize their performance in these crucial aspects of the game.
Conventional putting and chipping techniques begin with a golfer taking an address position similar to that depicted in
As the golfer prepares to strike the golf ball with a short chip or putt, the golfer withdraws the club head in a curved path generally along imaginary line E as shown. In a typical chipping or putting stroke, the golfer's shoulders and hips veer at least momentarily from the preferred “squared” address and contact position. Adding further complexity to the stroke, the golfer's arms and wrists are used to maneuver the golf club from a backswing position though the contact position. When practiced perfectly, the face of the club head begins at address in the preferred “squared” position, is moved to an open position during the backswing, and is returned to a squared position at contact. Unfortunately, however, most golfers are not able to perfectly practice this relatively complex movement on a repeating basis. The predictable result is that the club head often fails to return to a squared position at contact, thus, resulting in the golf ball being deflected from the target line A.
The above swing complexities and resulting deficiencies are further exacerbated as the golfer attempts short- to mid-range shots around the green. In order to make flush, consistent contact with the golf ball, it is desirable for the golfer's eyes to be squarely focused on the golf ball positioned generally in front of the golfer's feet as shown in
Thus, it would be desirable to develop a short-range golf swing technique and associated golf clubs that are adapted to take full advantage of a golfer's binocular vision and the improved depth perception associated therewith. It is further desirable to provide a technique and associated golf clubs that accommodate a golf swing movement whereby the number and complexity of arm, trunk, and shoulder movements that must be practiced to effectively stoke a golf ball along a preferred target line are reduced.
BRIEF SUMMARY OF THE INVENTIONThe above needs are addressed and other advantages are provided by an improved pendulum-style golf club and associated side-pendulum swing technique. Unlike conventional golf clubs and traditional swing techniques, the pendulum-style golf club and the side-pendulum swing technique of various embodiments of the present invention are specifically designed to maintain a golfer's binocular focus on a target while simultaneously reducing the number and complexity of movements that are required to practice a repeatable golf swing.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING(S)Having thus described the invention in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. Indeed, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
As will be described in greater detail below, the present invention is directed an improved pendulum-style golf club and an associated side-pendulum swing technique.
For purposes of the foregoing specification and appended claims the term “pendulum-style golf club” refers to a wedge, putter or other short range golf implement that is adapted for use by a golfer positioned in a binocular side-address position. The term “short range” as used herein refers to a golf shot distance wherein the target (e.g., golf green, golf hole) is less than 100 yards from the golfer.
For purposes of the foregoing specification and appended claims, the term “binocular side-address position” refers to a golf address position or stance wherein the golf ball is positioned outside of, and immediately adjacent to, the golfer's feet as shown in
In the depicted embodiments, the pendulum-style golf club 24, 124 is positioned adjacent the right-side of the golfer 20, 120. The golfer 20, 120 grasps the first end 26A, 126A of the shaft 26, 126 with an upper hand 42, 142 (the left hand as shown) and grasps a mid-portion 26C, 126C of the shaft 26, 126, located between the first end 26A, 126A and the second end 26B, 126B, with a lower hand 44, 144 (the right hand as shown). In alternate embodiments, for example where the golf ball 22, 122 is positioned on the left side of the golfer 20, 120, this hand positioning may be reversed as will be apparent to one of ordinary skill in the art. In the depicted embodiments, the upper hand 42, 142 is that which is furthest from target line A and serves to anchor the first end 26A, 126A of the shaft 26, 126 generally adjacent the golfer's shoulder as shown. In other embodiments, however, the upper hand 42, 142 may secure the first end 26A, 126A of the shaft generally adjacent the golfer's right side or armpit area. The lower hand 44, 144 is that which is closest to the target line A and is used to drive the golf club 24, 124 along a swinging pendulum motion as shown collectively in
In contrast to prior art swing techniques, the face 29, 129 of the golf club head 28, 129 does not deviate substantially from a perpendicular orientation to the target line A during the backswing and follow-through motions of the above described side-pendulum swing technique. Accordingly, it is easier for the golfer to make flush and repetitive contact with the golf ball 22, 122. The repeatability of the side-pendulum swing technique is further enhanced by reducing the number of muscle groups that are needed to perform a characteristic swing. In prior art golf swings, several muscle groups including those needed for controlling a golfer's hips, shoulders, trunk, arms, and wrists are generally used. Advantageously, swing techniques according to various embodiments of the present invention require relatively fewer muscle groups such as those necessary to swing a golfer's lower hand 44, 144 and arm along the target line A.
A desirable byproduct of the above referenced side-pendulum swing technique, as shown in
Detailed views of a pendulum-style putter head 28 structured in accordance with one embodiment of the present invention are depicted in
Pendulum-style golf clubs structured in accordance with various embodiments of the present invention are structured to possess a weight, shaft diameter, and shaft stiffness that is tailored to assist a golfer in practicing a side-pendulum swing technique. For example, in various embodiments, a pendulum-style putter head may be provided having a weight between 11 and 32 ounces, preferably between 12 and 28 ounces, and more preferably between 13 and 24 ounces. In one embodiment, such putter heads may be comprised of a composite material. For example, in one embodiment, the putter head is composed of a two part composite produced from a polyester resin, such as ArmorCast™ CD-10 series polyester resin produced by Cook Composites and Polymers of Kansas City, Mo., and an aluminum trihydrate filler. Other putter head embodiments may be comprised of metals, woods, cement materials, polymers, and the like.
As will be apparent to one of ordinary skill in the art, putter heads structured in accordance with various embodiments of the present invention may be significantly heavier than traditional putter heads. This additional weight provides added momentum and encourages a slow and steady pendulum motion. Conventional putter club heads may weigh between approximately 300 to approximately 350 grams, while pendulum-style putter heads of various embodiments of the present invention may weigh between approximately 11 ounces and approximately 32 ounces (312 grams to 907 grams), and more preferably weigh between approximately 13 ounces and approximately 24 ounces (369 grams to 680 grams) as noted above.
In still other embodiments, the pendulum-style putter 24 may include a shaft 26 that is relatively stiffer, longer, and heavier than putter shafts used to putt via conventional techniques as described with regard to
Whereas a conventional steel putting shaft may weigh approximately 120 to 140 grams, pendulum-style putter shafts structured in accordance with various embodiments of the invention weigh from approximately 17⅓ ounces to approximately 21 ounces (496 grams to 595 grams). As used herein, the term “effective weight” refers to the weight per unit length of a golf club shaft. Taken without a grip, pendulum-style putter shafts structured in accordance with various embodiments of the present invention possess an effective weight between approximately 0.4 ounces per inch and approximately 0.5 ounces per inch, preferably, approximately 0.46 ounces per inch. The relatively higher shaft weights of various embodiments of the present invention, as compared to prior art golf clubs, are tailored to encourage a simpler, more repeatable, side-pendulum swing movement.
In another embodiment of the present invention, the top surface 34 of the pendulum-style putter head 28 is structured to include targeting indicia that is adapted to assist a golfer in aligning the putter head with an intended target and making consistent, repeatable contact with a golf ball. The depicted targeting indicia comprises a first focal pattern 205A, an impact focal pattern 205B, and a second focal pattern 205C. The first and second focal patterns 205A, 205C are disposed on opposite sides of the putter head 28 generally adjacent the front or impact surface 29 of the putter head 28 as shown. The depicted impact focal pattern 205B is disposed centrally on the top surface 34 of the putter head 28 and is structured to terminate at a preferred impact region IR along the front surface 29 as shown. Although depicted centrally, the impact focal pattern may be offset relative to center in embodiments where the preferred impact region IR of the putter head is itself offset relative to center.
The depicted first and second focal patterns 205A, 205C are comprised of a plurality of lines 206 that extend rearward from the front surface 29 of the putter head 28 as shown. The depicted first and second focal patterns 205A, 205C are comprised of five lines; however, more or fewer lines of varying thicknesses may be used. In addition, the first and second focal patterns 205A, 205C need not be comprised of lines and may be comprised of a solid shape, pattern, or other indicia. In one embodiment, the first and second focal patterns 205A, 205C each define a rear contour that is aligned with imaginary first and second focal axes 201, 202 as shown in
The impact focal pattern 205B assists a golfer in maintaining the front surface 29 of the putter head square to the target line as will be apparent to one of ordinary skill in the art. The depicted impact focal pattern 205B is comprised of a plurality of lines 206 that extend rearward from the front surface 29 of the putter head 28 as shown. The depicted impact pattern 205B is comprised of five lines; however, more or fewer lines of varying thicknesses may be used.
The first focal pattern 205A, the impact focal pattern 205B, and the second focal pattern 205C may be formed on the upper surface of the putter head 28 by a number of techniques so long as the each focal pattern is visible to a golfer in an address position. For example, the focal patterns may be etched, embossed, painted, or otherwise transferred to the top surface of the putter head through decals, coatings, or the like. Although depicted on a “mallet-style” putter head, the above-described focal patterns are not limited to the depicted putter head style and may be transferred to any putter head style as will be apparent to one of ordinary skill in the art.
Detailed views of a pendulum-style chipping club 124 are depicted in
Pendulum-style chipping heads may be comprised of composite materials that are configured to make the pendulum-style chipping club much heavier than a conventional chipping club. For example, in various embodiments, a pendulum-style chipping head may be provided having a weight between 11 and 32 ounces, preferably between 12 and 28 ounces, and more preferably between 13 and 24 ounces. In one embodiment, the pendulum-style chipping head is composed of a two part composite produced from a polyester resin, such as ArmorCast™ CD-10 series polyester resin produced by Cook Composites and Polymers of Kansas City, Mo., and an aluminum trihydrate filler. Other pendulum-style chipping head embodiments may be comprised of metals, woods, cement materials, polymers, and the like.
As will be apparent to one of ordinary skill in the art, pendulum style chipping heads structured in accordance with various embodiments of the present invention may be significantly heavier than traditional chipping heads. This additional weight provides added momentum and encourages a slow and steady pendulum motion; even despite the ground (e.g., turf, sand, etc.) collisions that are anticipated for a chipping club. Conventional chipping club heads may weigh between approximately 280 to approximately 300 grams, while pendulum-style chipping heads of various embodiments of the present invention may weigh between approximately 11 ounces and approximately 32 ounces (312 grams to 907 grams), and more preferably weigh between approximately 13 ounces and approximately 24 ounces (369 grams to 680 grams) as noted above.
In still other embodiments, the pendulum-style chipping club may include a shaft that is relatively stiffer, longer, and heavier than chipping club shafts used to chip via conventional techniques as described with regard to
Whereas a conventional steel chipping club shaft may weigh approximately 120 to 140 grams, pendulum-style putter shafts structured in accordance with various embodiments of the invention weigh from approximately 17½ ounces to approximately 21 ounces (496 grams to 595 grams). Further, whereas a conventional chipping club shaft length may be from approximately 36¼ inches to approximately 41¼ inches, pendulum-style chipping clubs may comprise shafts defining a length between approximately 38 inches to approximately 46 inches. Thus, pendulum-style chipping clubs structured in accordance with various embodiments of the present invention may define an effective weight between at least 0.4 ounces per inch and approximately 0.5 ounces per inch, preferably, approximately 0.46 ounces per inch. The relatively higher shaft weights of various embodiments of the present invention, as compared to prior art golf clubs, are tailored to encourage a simpler, more repeatable, side-pendulum swing movement.
