2. Description of the Related Art
The three biggest barriers to entry in golf have been identified by industry sources as difficulty, time and expense. A fourth barrier to entry is accessibility or location. This barrier is huge because millions of people simply do not have easy access to a golf course or driving range. In addition, the same industry sources identify the two biggest reasons that people play golf as: 1) the excitement of hitting a ball and 2) socializing. Nothing else is close. The game of golf has always had its followers, but in recent years, interest in the sport has dramatically increased. The game's difficulty and expensive equipment, however, represent significant barriers to people's participation.
For decades, if not centuries, golf club manufacturers have focused their technological advances on making the ball go farther and straighter when hit. Club manufacturers know that many golfers will spend thousands of dollars on new advances in equipment. They realize that many players are looking to “buy” skill. However, a golf club will only perform as well as the person swinging it. Unfortunately, these technological advances have done little to make the ball substantially easier to hit. Today's golfers are using virtually the exact same clubs used by PGA stars. These golfers are expected to go to the golf course, learn the game and perform well. This is unrealistic considering the enormous difficulty of the game as currently played. It is unfair and impractical to expect people who have a minimal amount of time to devote to practice to perform effectively with these clubs.
Of golf's difficulty, time, expense, and accessibility barriers to entry, the game's difficulty is probably the largest barrier to entry. The golf swing consists of a synchronized motion around the axis of the spine. When a person is standing upright, their head, shoulders, arms, hips, legs and feet are in a relaxed, natural and comfortable position. When a right-handed person is given a golf club and looks down at the ball, the golfer must tilt their spine angle, drop their right shoulder lower, lean forward at the hips and look down at the ball. This tilting, dropping, leaning and looking down disrupts the natural relationship between the head, shoulders, arms, hips, legs and feet. The body now is in an unnatural or “disoriented” position.
This creates many problems because each part of the body now becomes “disoriented” and independent relative to the other body parts. When one of those body parts moves independently from the other parts during a golf swing, there is a “disconnection” in the swing. The golfer must re-educate each body part to perform in a synchronized way. This is a reason why the game can be so frustrating and difficult. It is also why the golf swing is so difficult to learn.
The seven major problems with a learning a golf swing include: 1) bending at the waist causes a change in body balance (this creates the environment for reverse pivoting, swaying, arm lifting the club, lifting the head and more); 2) bending at the waist disrupts normal body alignment (the head, shoulders, waist, and legs are now out of alignment); 3) bending at the waist causes the eyes' position to change from a normal “stereoscopic” to a “monoscopic” perception; 4) the length of the club; 5) the size of the club face; 6) the ball is as far from eye level as possible; and 7) the golf swing requires a “reflex” body action that uses a club to hit a stationary ball to a stationary target. The golfer must create this “reflex” action because the ball is static or not moving. In effect, every new golfer has seven very difficult problems to deal with and master all at the same time. Ball striking and rotation are very difficult concepts from this “traditional” position. The “Swing Problems” listed above and more commence immediately in multiple combinations. Players become so confused that they can't hit a stationary ball. They become frustrated and humiliated and many eventually quit.
Therefore, there exists a need for an improved golf training device and method particularly for a training device and method that effectively and inexpensively trains a player for playing golf with a traditional golf club. Thus, a golf swing training apparatus and method solving the aforementioned problems is desired.
The golf swing training apparatus provides a golf club and method that eliminate each of the above-described barriers to entry. The golf club and method are a progressive training aid that allows a fundamentally sound golf swing to be efficiently built in stages from a waist high ball position to the ground. The specially designed golf club and “graduated height tee system” quickly delivers the fun and excitement of hitting a golf ball. The present invention and its “Top Down” approach yield immediate positive results. The present invention's functionality and portability has “Universal Reach” and can help golfers of all skill levels from beginner children to PGA tour players.
The golf club and method also reinforce the two biggest reasons that people play golf: 1) the excitement of hitting a ball and 2) socializing. The present invention delivers the excitement of hitting a golf ball and the opportunity to socialize while playing golf faster and more efficiently than any golf product in the world. After a “golf swing foundation” is built the player can use the “graduated tee system” to progressively build spine angle into the swing. Each student may advance at their own pace depending on their individual athleticism. Everyone immediately gets the excitement of hitting a golf ball.
Each of the main barriers to golf and how the present invention reduces these barriers will now be described. Difficulty: The present invention makes hitting a golf ball easier than ever by: 1) a shorter shaft, 2) a bigger club face and 3) moving the ball closer to eye level. The specialized club and “graduated height tee system” of the present invention rapidly accelerates learning the proper mechanics for the golf swing. The present invention quickly delivers the excitement of hitting a golf ball. The present invention also allows players to progressively add spine angle (bending at the waist). Players do this by using the next lower height tee at their own pace depending on their athleticism.
Time: The present invention rapidly teaches a fundamentally sound golf swing. With the present invention, a wonderfully sound golf swing can be developed in a matter of minutes. The present invention immediately delivers the excitement of hitting a golf ball, rapidly accelerates learning proper swing fundamentals and gives each player a huge dose of confidence and fun. In addition, the number one problem on golf courses is slow play. Five to six hour rounds are common at many courses. This problem “gums up” the works and discourages play. However, this “time” problem will always exist with the games current format. Beginners and lesser skilled players want to learn but cannot hit the ball. These beginners and high handicap players with conventional clubs create extraordinarily long rounds. This “slow play problem” costs the game dearly both financially and by frustrating other players. The present invention accelerates the pace of play on the course because golfers using the present invention can hit the ball consistently.
Expense: The equipment of the present invention is inexpensive. The present invention offers a huge financial opportunity to the world of golf. Golf courses can give golfers using the present invention a break on greens fees and have a separate teeing ground for them perhaps at the 150-yard marker. With this format, the present invention offers each facility a “New Market” and revenue stream. The USGA may also offer a special handicap system for the present invention that incorporates existing technology. This will give the USGA a better ROI (Return on Investment). Each course may be “Rated” at 54 for Starters. This format gives everybody the chance to hit the ball, socialize, have fun and compete. It can also generate large revenue and growth for the game. Everybody, especially the game of golf, wins when these golfers graduate to conventional equipment or even if they remain golfers using the present invention. This is also a wonderful way for physically challenged individuals to enjoy golf. Also, senior citizens playing golf using the present invention represent a huge potential growth resource for golf.
Accessibility or location: The present invention delivers a constructive and fun golf experience to the neighborhood and inner city. Golf has traditionally been taught at driving ranges and golf courses. The present invention offers a portable and fundamentally sound learning experience that includes these two venues plus everywhere else. The present invention may be used with golf balls and many other ball types in neighborhoods, in the inner city, at parks, schools, on grass, asphalt, backyards and the like. The present invention introduces a new era in golf instruction and playability. This is all accomplished while maintaining the essence, tradition and competitive elements that have made golf one of the world's most popular sports.

Referring to
The golf training system described herein offers the golfer the opportunity to learn golf from the “top down”. This “top down” approach to teaching the modern swing will yield quicker results and success. Today's modern swing mechanics require that the golfer keep the club in front of the body. This position keeps the club from getting trapped behind the golfer where all sorts of problems occur. Many of golf's finest instructors accurately describe the golf swing as similar to a baseball swing, but on a different plane. Common swing problems such as: “head lifting”, “hips swaying”, the “reverse pivot”, “arm swing”, “flat swing”, “upright swing” and more, can all be identified and corrected with the present system. For good players, the system will help identify swing flaw tendencies or “disconnections” when things go bad. One “disconnection” occurs when golfers lift their heads when they swing.
The present system enables the golfer to quickly feel the benefit of synchronizing the shoulders, hips and legs around the spine axis in developing proper swing mechanics. Concepts such as balance, rotation, connection, keeping the club in front of the player and more are automatically taught by use of the present invention. By placing the ball on an elevated tee closer to eye level, the player may assume a much more natural position and be taught proper swing mechanics in a more relaxed and enjoyable format.
In some embodiments, as illustrated in
In one embodiment, the shaft 110 of the club is straight and has a circular cross-section. However, other cross-sectional shapes can be used, such as polygonal, elliptical, octagonal and other round shapes. The shaft can be made of a metal, such as steel, but any other materials can be used. Examples of materials that can be used include titanium, graphite, hard plastics, polymers, composites, other metals, or combinations thereof.
The grip 120 is similar to a grip used with traditional golf clubs. The grip 120 has a cylindrical shape and includes a tubular opening, having an inner diameter adapted to receive the shaft 110. In many embodiments, the inner portion of grip 120 is adapted to the shape of shaft 110. Accordingly, if shaft 110 has a non-circular cross-section, at least the inner tubular portion also has a corresponding or complimentary cross-section. The grip 120 can be molded to the shape of the hands. The grip 120 can be made of rubber, leather, or other materials.
With reference to
Club head 136 includes a number of axes, X and Y in
The face 135 of the club may also include a surface treatment 145, which can be decorative and/or functional, as shown in
The diameter of the face 135 can range from about 3-6 inches in some embodiments, and about 4-5 inches in other embodiments. The total volume of the club head 130 can range from about 300-600 cc, and is about 340 cc in one embodiment. The club head 130 has a mass ranging from about 300-600 g in some embodiments, and is about 335 g in one embodiment. The values provided are merely exemplary, however, and the dimensions and mass of the club head 130 can vary significantly to improve the ease of use and stability of the club.
The additional weight of the club head and shorter length of the club shaft provide improved stability in many embodiments. By shortening the length and increasing the mass, the club 100 has a lower moment of inertia about the longitudinal axis of the player's spine. The club 100 is easier to swing because the moment of inertia about the axis passing through the player is lower. The club 100 has a higher moment of inertia about a longitudinal axis passing through the length of the club. The ability of a club head 130 to resist twisting during off-center hits is desirable, especially to recreational golfers, who frequently make contact away from the center of the club face 135. A club with a low moment of inertia about the axis passing through the club tends to twist open or closed depending on the contact location, and the direction of the shot suffers. A higher moment of inertia makes the club head 130 more resistant to twisting, resulting in a generally straighter shot. The enlarged hitting surface 135 also improves a player's ability to hit the ball.
The club 100 can be made from any manufacturing methods for producing golf clubs, such as forging, molding, brazing, welding, and/or casting, although other manufacturing techniques can be used as well. Forging involves producing a golf club head from a series of forging dies, and stamping the head to a final shape. Forged heads are typically made of softer metals than cast heads and can require hand finishing and chrome plating. Compression molding is typically used with composite materials. Molding involves layering graphite or other materials and heat curing the layers to create a club head. In some embodiments, the grip 120 can be attached to the shaft 110 using compression fit techniques. In certain embodiments, adhesives can also be used to apply the grip 120 to the shaft 110. Alternatively, the grip 120 can be formed with the shaft 110. In one embodiment, the shaft 110 can be removably attached to the club head 130.
With reference to
The shaft 152 of the tee is generally straight and can have a circular cross-section. However, other cross-sectional shapes can be used, such as such as polygonal, elliptical, octagonal and other curved or non-curved shapes. In some embodiments, the shaft 152 can be curved. The cross-sectional diameter can vary as well, such that the diameter is greater at the tip 154 and smaller at the tee top 156, or vice versa. In certain embodiments, the shaft 152 is made of a metal, such as steel or titanium, but other materials, such as graphite, composites, polymers, hard plastics, or combinations thereof can be used. The length of shaft 152 is variable as described below.
Tip 154 is located at the bottom end of shaft 152. Tip 154 can include a base 158 and an extension 159. The base 158 can be circular and can have a wider diameter than both the extension 159 and the shaft 152. Any other shape that provides stability can be used. The base 158 provides structural support to the tee 150, such that the tee 150 has stability when placed in the ground. The extension 159 can be tapered at its bottom-most portion, such that the tip easily enters the ground and is of adequate length to provide stability and remain in the ground. In use, the extension 159 is within the ground, while the base 158 is just above the ground, resting on the surface.
Tee top 156 can be a tubular member that fits over the top end of shaft 152. In many embodiments, the tee top 156 is a resilient material, such as rubber. Tee top 156 provides flexibility to the tee 150, such that there is minimal movement of the shaft 152 and tip 154 when the club 100 hits a ball and, possibly, the tee 150.
In certain embodiments, each part of the tee 150 is formed separately, and assembled using compression fit techniques. The shaft 152 and tip 154 can be manufactured as an integral unit, with the tee top 156 assembled using compression fit techniques. Other methods, such as, for example, welding, brazing, and adhesives can be used to secure the shaft 152, tip 154, and tee top 156 together.
In one embodiment, the beginner tee 160 is about waist high. In certain embodiments as illustrated in
By providing a number of tees 160, 170, and 180 of varying lengths, a player is able to gradually adjust their swing level as their skills progress. The player may start at the beginner tee 160, and work down to the intermediate tee 170, and then to the advanced tee 180, such that proper swing mechanics are developed gradually, however, any number of different heights can be used. The gradual variation in tee height allows a player to adjust from a first swing, which is similar to a baseball swing, to a traditional golf swing.
Referring to
The length of the club 100 can also be adjusted. The club length can be adjusted simultaneously with the adjustment of the tee height. Alternatively, a player can adjust between tees 160, 170, and 180 using the same length club 100, and subsequently increase the length of club 100.
The tee 150 should be firmly implanted into the ground, unless other methods of supporting the tee 150 are provided. In some embodiments, which are not shown, the tee 150 includes a tip 154, which permits the tee 150 to support itself on the ground without being implanted.
With reference to
The shafts 252 are generally straight and can have a circular cross-section. However, other cross-sectional shapes can be used, such as such as polygonal, elliptical, octagonal and other curved or non-curved shapes. In some embodiments, the shafts 252 can be curved. The cross-sectional diameter can vary as well, such that the diameter is greater near a bottom of the shaft 252 and smaller at the tee top 256, or vice versa. The shafts 252 may be made out of a hard plastic material, or, in other embodiments, the shafts 252 is made of a metal, such as steel or titanium, or other materials, such as, but not limited to, graphite, composites, polymers, hard plastics, or combinations thereof can be used. As indicated above, the removable shafts 252 come in different lengths (beginner 260, intermediate 270, and advanced 280). For example, someone just starting off with the golf club 100 may use the beginner shaft 260 with the tee support 254. Someone of intermediate level may use the intermediate shaft 270 with the tee support 254. Someone of advanced level may use the advanced shaft 280 with the tee support 254. By incorporating different-length shafts 252, only one tee 250 is needed for different skill levels.
The tee support 254 is located at the bottom end of shaft 252. The tee support 254 includes a frusto-conical base 258 and a hollow neck 259. Although the base 258 is described as being frusto-conical, in alternative embodiments, the base 258 may have other configurations (e.g., rectangular block-shaped, triangular block-shaped, etc.). The base 258 is made of a hard rubber material, and includes a ballast therein to provide structural support to the tee 250, such that the tee 250 has stability when placed on the ground. The hollow neck 259 slidably receives the shaft 252. The tightening mechanism 255 can be loosened to facilitate removal of and insertion of the shaft 252, and tightened to retain the shaft 252 in the neck 259. In the embodiment shown, the tightening mechanism 255 is a metal collar with a tightening key that is rotated to tighten and loosen the collar around the neck 259. In other embodiments, other tightening mechanisms may be used.
The tee top 256 can be a tubular member that fits over the top end of shaft 252. In many embodiments, the tee top 256 is a resilient material, such as rubber. Tee top 256 adds flexibility to the tee 250.
In certain embodiments, each part of the tee 250 is formed separately, and the shaft 252 and the tee top 256 are assembled using compression fit techniques. Other methods, such as, for example, welding, brazing, and adhesives can be used to secure the shaft 252 and the tee top 256 together.
The height of the tee 252 with the shafts 252 (beginner 260, intermediate 270, and advanced 280) correspond to those described above with respect to
In use, the tee 252 is placed on a flat surface, and the appropriate-length shaft 250 is provided with the tee support 258. A user places a golf ball on the tee top 256, and swings at the golf ball with the golf club 100. If the club head 130 hits too low on the tee top 256/shaft 250, the tee 250 will topple over, instead of being knocked too far from the user. The weighted nature of the tee support 258 causes the tee 250 to topple over when the club head 130 hits too low on the tee top 256/shaft 250, preventing the tee support 258 from moving too far from its original position. This prevents the tee 250 from being knocked too far from the user. By providing a single tee 252 with varying lengths, players are able to gradually adjust their swing level as their skills progress. The player may start the tee 252 at the beginner length 260, and work down to the intermediate length 270, and then to the advanced length 280, such that proper swing mechanics are developed gradually. The gradual variation in tee height allows a player to adjust from a first swing, which is similar to a baseball swing, to a traditional golf swing.
An example of how to play on a golf course using the equipment described herein will now be explained. In certain embodiments, the player tees off using their club 100 with the tee 150, 250. Subsequent shots can be played by placing the tee 150 in the general vicinity where the ball lies, such as directly behind, in front of, on the side of the ball, or any other desirable location. The player can use the tee 150 anywhere on the course, including bunkers and hazards. The ball can be lifted and placed on the tee 150, 250 and hit again, until the green is reached. In some embodiments, when on the green, the player uses the club 100 as a traditional putter, without the tee. However, the club 100 can be used without a tee 150, 250 at any other location as well.
In certain embodiments, the beginner tee 160, 260 can be used for shots around the green. The player can choke up on the club 100 and open the face 135 towards the sky to decrease the distance the ball travels. In this position, the ball can be hit high and soft for improved control. In some embodiments, the golfer can try to hit “line drives” that fly straight off the tee 150, 250.
The club 100 helps golfers focus on developing proper swing fundamentals and eye-hand coordination. The club design of some embodiments more than doubles the club face hitting area of the club 100 compared to that of existing club face hitting areas. Also, the club 100 has a decreased shaft length, which reduces the “swing arc” and makes the club 100 easier to control. Furthermore, the tees 150, 250 put the ball in a more natural position to be hit with a swing similar to baseball or tennis. By placing the ball closer to eye level, the player's eye-hand coordination is improved. The benefits of these advances can be immediate and enormous. The ball is more easily hit, thereby enhancing the individual's experience, making the game more enjoyable.
Embodiments of the club 100 and tees 150, 250 also make the game less frustrating and physically demanding. The system accelerates the pace of the game, while maintaining the essence, tradition and competitive elements that have made golf one of the country's most popular sports.
With the system described herein, the golfer learns to keep their eyes on the ball. Another example of a common “disconnection” would be the “swaying” of one's hips. This is a major flaw for many amateurs. By swinging embodiments of the club 100 as described herein, a player is able to identify and correct flaws in his swing mechanics. With the systems and methods as described herein, a player cannot sway off the ball without feeling the problem. After a short time, the lower body should reconnect to the normal swing and swing mechanics should return to normal. The training system enables golfers to quickly re-center their swing around the “spine” axis of the spine.
The golf training system described herein: (1) places the ball closer to eye level in a more natural position to be hit with a swing similar to that used in baseball or tennis; (2) more than doubles the club face hitting area; and, (3) decreases the length of the club 100, which reduces the “swing arc”, making the club easier to control. By gradually reducing the height of the ball on the tee, the player is able to comfortably step down to a traditional golf swing.
The game of golf has never been taught with this type of specialized equipment using a “top down” approach. Golf has been taught for centuries with a ball on the ground position. The club design and graduated (progressive) tee system are industry breakthroughs and completely unique. The golf training system described herein provides many advantages, some of which are described below. The golf training system makes the ball easier to hit and accelerates playing time, which results in more time spent socially with family and friends. The golf training system also reduces anxiety, humiliation, fear, and intimidation. The system provides a great teaching aid by accelerating and encouraging players to learn proper swing mechanics. The club also provides for better ball control. The same club can be used by both right and left handed players. Many embodiments of the club may be used for all shots including putts, so that only one club is required during an entire game, although more than one club can be used. Existing golfers may use the system to work on their mechanics. The system can also result in an expansion of the golfing public, because of the reduced cost, reduced frustration and improved efficiency. Furthermore, older or injured players will be able to prolong their golfing careers or even learn the game for the first time.
