BACKGROUND OF THE INVENTION Although the swinging action in the swinging sports looks simple, it actually requires many necessary standard swing postures to perform a perfect and accurate swing action. There are many important aspects required to produce a perfect swing action according to experts in the art. First, extreme care should be taken to provide for a proper grip. Second, the posture should be maintained level throughout the swing with the knees sometimes bent. Third, the backswing should be perfect, for example: if a baseball player over-backswings the bat, he or she will not see the ball coming to him or her, If a golf player does the same thing, his or her head will turn and cannot see the ball any more, and how could a player hit a ball that he or she can not see. Fourth, the downswing should be powerful and accurate using the two hands because hitting the ball or hockey puck with one hand is not strong enough. Fifth, the ball or puck impact should be on the right place, so that the ball or puck will be at the center of the face of the club, hockey stick or bat etc., while said club, hockey stick or bat etc. is exactly perpendicular to the optimal swinging plane. Sixth, the follow-through should be all the way and in the direction of the intended destination of the ball or puck. Seventh, the player must stop his or her swing at the right time and not over swing the club, hockey stick or bat etc. otherwise the player will injure himself.
Perhaps the most important aspect required to perform an accurate swing action in swinging sports is for the player to swing and hit the ball, or puck in the optimal swinging plane. For example, the optimal swinging plane for a swinging sport such as golf, baseball and cricket etc. is constructed by the connection of three points between the left and right shoulders of the player and the point of his or her two hands holding the club, hockey stick or bat etc. If the player can swing the club, hockey stick or bat etc. to enable the club, hockey stick or bat etc. head to travel along the same optimal swinging plane each time, the player's swing action will be very accurate and perfect which will enable the player to hit the ball to travel exactly towards the target. On the other hand, if the player fails to hit the ball in the optimal swinging plane, the ball will be hit to travel into an unexpected destination. If the player's two hands are straight and fully extended it will help keep the optimal swinging plane intact, however, most of players, especially in baseball and cricket bend their arms at the elbows. This happens because they put the bat behind their head to start swinging which make it impossible to keep an optimal swinging plane intact. The dilemma is that all the players, professionals and amateurs alike, of swinging sports such as golf, baseball and cricket etc. cannot keep the optimal swinging plane intact during their swing. This happens because when the player starts moving the club, hockey stick or bat etc. over his or her head the left hand of the right handed player for example will prevent the player's two hands from being straight, and force the left and right hand to bend over the head. This will force all the players without exception to move the head of the club, hockey stick or bat etc. in a radical, spiral, uncontrollable and shaking motion away from the optimal swinging plane. When the player is going for his or her downswing and their arm becomes extended (straight) they will try very hard to go back to the optimal swinging plane, sadly most of them fail to do so resulting of hitting the ball astray.
The player of a swinging sport may injure himself if he or she did not pay attention and stay alert at all times and be careful with his or her swing. For Example, one day my friend told me while we were practicing golf in a driving range, to watch out and not to hit the ground or the ball at the wrong place or I will injure myself. I did not pay attention and I hit the ball at the far edge of the golf club face and suddenly the club was violently twisted in my hands and many ligament of my right wrist was torn. It took me over four months to heal from this injury. Thank God this happened to me, because it inspired me to invent this invention. Many golf, baseball and cricket players go home with a sore wrist or twisted leg after playing or practicing. It ranges from minor to severe injuries such as twisted arms, legs and backs, etc. Studies in the United States show that between 40 and 50 percent of all golfers, professionals and amateurs alike, suffer from back problems. Back injury is the most common golf injury, caused mostly due to over-swinging. Said injuries force many players to stop playing the sport and tell other people not to play it. This will result into a bad name and ruin the reputation of the sport. According to statistics, one unsatisfied person is equal to 50 satisfied ones, because the unsatisfied person will go around spreading the bad gospel to 50 other people.
Swinging sports are very old sports. Thousands of devices were created to improve the games, however, the players of such sports still insist on holding the club, hockey stick or bat etc. with his or her two hands, where the two hands are close to each other. I think this bad habit did not change after all these years because the player of said sports needed to hit the ball with his or her two hands so that he or she can hit it strong enough to play the game. Hitting the ball with one hand cannot produce the desired force needed to play the game. On the other hand, holding said club, hockey stick or bat etc. with the two hands and near each other does not only make the game difficult and impossible to play as mentioned above, but also makes said club, hockey stick or bat etc. sway and swing in uncontrolled radical directions and almost never in the optimal swinging plane. No matter how many hours a player will train for the swinging games he or she may never achieve any progress at all. As a matter of fact, some players keep practicing the swinging sport in an incorrect way, such that their body becomes used to it, resulting in injury. Such hopeless effort forced many players to abandoned the sport and tell other people to forget about it and not to even try to play it. This drives many people away from such sports.
Chipping the ball in golf is very difficult. Chipping refers to hitting the ball with a club that has a tilted head to hit the underneath the ball to make it travel high in the air. First the player has to choose the correct club number with the correct tilted angle for the distance, second, the player must put the ball in the middle distance between his or her legs because he or she is holding the club with his or her two hands and the only chance that he or she may hit the ball in the optimal swinging plane is to put the said ball in the middle distance between his legs. Third, the player will go for his upper swing, which will throw him or her away from the optimal swinging plane as we described above. Fourth, the player will go for his or her downswing and make sure that he or she will chip the ball at the right spot under the ball to make it go up into the air to the correct height and the correct distance. The chance of chipping the ball correctly in golf is very small and almost impossible to do, no matter how much the player will practice his or her chipping he or she will chip the ball in a different way and at a different spot for the same distance and never get it correctly. The player needs a better method to chip the ball.
Putting in golf is also very difficult for all players because it is very hard for the player to swing the putter in the exact direction he wanted. First the player may stand behind the ball and line it up and then he may kneel down and use his putter to line up the direction for the second time. Then he stands and swings the putter to practice away from the ball and parallel to the ball. Then he takes one step ahead, makes sure that the ball in the middle distance between his legs and puts the face of the putter very near to the ball and one final time he swings his head to make sure that it will go straight to the hall and hit the ball. In most cases the ball will go astray. The golf player needs an accurate and reliable way to test swinging the putter in the direction of the hall several times before finally hitting the ball.
Swinging sport such as golf require a golf club set which is heavy to carry and expensive to buy. The player needs to use fewer clubs to play the game and make it affordable to buy and play the game.
Swinging sports such as golf having hard time attracting young kids to join them. You will find most of the players are adults and big portions of them are seniors. The reasons are very clear. The younger people are not interested. We need to make the game more interesting and exciting for the young people to make them play the sport.
Also in swinging sports such as tennis, racquetball, and squash etc. the player uses only one hand to hit the ball while the other hand is doing nothing during the game. However, hitting the ball with one hand is not strong enough. When the ball is coming to the left side of the right handed player of tennis for example, sometimes the player suddenly holds the racket with his or her two hands and hits the ball resulting in hitting the ball much stronger. However, with all the problem of holding the racket with the two hands near each other mentioned above, the ball probably will go astray. Holding the racket with two hands is very much needed especial in hitting the surf in tennis to hit the ball stronger and make it travel faster, providing that we can find a solution to the obstacles mentioned above.
OBJECTS AND SUMMARY OF THE INVENTION It is difficult for the average player of swinging sports to play, practice and make a perfect swing, Therefore, it is a general object of the invention to provide a new method and device to enable the player to play, practice and swing in a reliable, consistent, controlled, accurate and safe manner.
There are a host of prior swinging devices designed to assist a player of swinging sport in performing with a consistent and better swing. Many of such devices are impractical and do not solve the above swinging problems. Moreover, some of them do not provide a natural pendulum swing that goes in harmony with the player's natural body motion. In fact some of them even restrict the player's body from natural movements. Therefore, it is the object of the invention to provide a method and device with a construction to be swung in a natural pendulum manner which will enable safe and improved swing in the optimal swinging plane or parallel to the optimal swinging plane that will result in a reliable, consistent, controlled, better, accurate and precise hitting while protecting the players from injury, improve the score and make the games more exciting and safe to play.
Most of the prior art devices are only for practicing the swing of the swinging games. Therefore, it is another object of the method and device of the invention not only to provide a training-swinging device, but also to provide a new method and device to play the games with that will increase the score and make the games more exciting and safe to play.
The prior art of playing swinging sports often injured the player as described above. Therefore, one of the most important objects of the method and device of the invention is to protect the player from any injury resulting from practicing and playing the swinging games, especially if it is a child learning to play the games.
The prior art does not allow the player to swing in optimal swinging plane as describe above. Therefore, another important object of the method and device of the invention is to provide the player with a method and device to swing in a natural pendulum-like way into or parallel to the optimal swinging plane. This will result not only in making it easy for the players to perform an accurate swing in the optimal swinging plane, but also it will increase the score, and make the games more exciting. This will result in making such swinging games more popular.
The prior art made it impossible for the player to maintain a good body posture during and after the swing, therefore, another object of the method and device of the invention is to enable the player to easily stand straight and maintain a good body posture throughout the swing without bending his or her knees. This will also result in improved swinging.
The prior backswing of swinging sports such as golf, baseball, hockey, and cricket etc. sometimes forced the player to over swing his or her backswing, which results in not seeing the ball or hockey puck as, mentioned above. Therefore, another object of the method and device of the invention is to stop such over swinging and keep the ball or hockey buck in the sight of the player at all times so that he or she can hit the ball or hockey buck and never miss it.
The prior downswing of swinging sports such as golf, baseball, hockey, and cricket etc. is powerful because the player is using his or her two hands to hit the ball or hockey buck, however it is not accurate because the player holds said club, hockey stick or bat etc. with his or her two hands close to each other as described above. Therefore, another object of the method and device of the invention is to make the player use his two hands to hit the ball or hockey buck stronger and accurately while solving the problem of the prior art.
The prior art of swinging sports such as golf, baseball, hockey, and cricket etc. made it impossible to hit the ball or hockey buck in the right place so that the ball or hockey buck will be at the center of the face of the club, hockey stick or bat etc., while said face of the club, hockey stick or bat etc. is exactly perpendicular to the optimal swinging plane. Therefore, another object of the method and device of the invention is to easily line up the face of the club, hockey stick or bat etc. to hit the ball or hockey buck at the center of the said club, hockey stick or bat etc. while the said face of the club, hockey stick or bat etc. is perfectly perpendicular to the optimal swinging plane, which will result in hitting the ball or hockey buck exactly in the right place and solve the problem of the prior art.
In the prior art of swinging sports such as golf, baseball, hockey, and cricket etc. the follow-through swing is hard to do in the optimal swinging plane because the player's two hands bend as he or she goes for the follow-through swing which will result in making the face of the club, hockey stick or bat etc. move in radical directions making the ball or hockey buck go astray. Therefore, another object of the method and device of the invention is to make the follow-through swing not only to go all the way in the direction of the intended destination but also in the optimal swinging plane.
The prior art of swinging sports such as golf, baseball, hockey, and cricket etc. made it very difficult for the player to stop his or her swing at the right time and not to over swing the club, hockey stick or bat etc. which results in injuring himself or herself. Therefore, another important object of the method and device of the invention is to enable the player to stop swinging at the right time and distance with ease that will protect the player from any injury during his or her playing or practicing the swinging games.
The prior art of swinging sports such as golf, baseball, hockey, and cricket etc. forced player to bend his or her hands when he or she swings the club, hockey stick or bat etc. over his or her head in his or her backswing which results in a radical movement of the face of the club, hockey stick or bat etc. away from the optimal swinging plane. Therefore, another object of the method and device of the invention is to solve the prior art backswing problem by keeping the hands of the player straight at all times and never bend the hands when moving said club, hockey stick or bat etc. over his or her head. This will result in a perfect backswing, which in turn produces a perfect hit in the optimal swinging plane, improve the score and makes the game controllable.
The prior art of swinging sports such as golf, baseball, hockey, and cricket etc. makes the club, hockey stick or bat etc. violently twist in the hand of the player. If such a player hits the ball or hockey buck in the wrong place or hits the ground in the golf game, it will result in a serous injury of his wrist, arm or back etc. Therefore, another very important object of the method and device of the invention is to stop such dangerous practices of the prior art by protecting the player from said violent twist at all times and make the game safe to play for adults and especially for kids.
The prior art made some of the swinging games such as baseball and golf very boring to play and watch. Therefore, another object of the method and device of the invention is to reverse the way people think and feel about such swinging games and make such games exciting to play, practice, and to watch.
The prior art of playing golf forced the player to place the ball in front or him or her and in the middle distance between his or her legs because he or she is holding the club with his or her two hands and the only chance that he or she may hit the ball in the optimal swinging plane is to put the ball in the middle distance between his or her legs. This action limits the player and forces him or her to only hit the ball with the angle of the club head depending on the club number, such club heads are fixed in their tilting angle, and a limited number of clubs are available to the player, each with a fixed tilt angle. Therefore, another object of the method and device of the invention is to enable the player to place the ball at any point in front of him or her between his or her two legs which will enable the player to shoot the ball with different angles using the same club—as if the invention added hundreds of different club heads with hundreds of different tilt angles for the player to shoot the ball with.
The prior art of playing golf requires the player to have a set of golf clubs. Such a set is expensive, which stops many people from playing golf. Therefore, another object of the method and the device of the invention is to enable the player to use fewer clubs to play golf because he does not need all of the standard clubs used for the prior art since he can control the tilting angle to hit the ball as we described above. This will allow the player to play golf using fewer clubs, make the sport more affordable for many people to play and increase the number of golf player around the World.
The prior art of playing golf requires the player to have a set of golf clubs and such a set is very heavy to carry. The golf player often needs a Caddy cart to put the set on it and pull it while playing or in many cases requires a second person (a helper) called simply the Caddy or the Caddy boy to carry the set of clubs. The Caddy is slowing down the game and making it often very difficult for one person to go and play by himself or herself dragging such a heavy load, Therefore, another object of the method and the device of the invention it to eliminate the use of the Caddy in the golf sport since the player will be able to play golf using fewer golf clubs, he or she will be able to carry them easily by himself or herself and enjoy playing the game. This will result in a big jump in the number of people playing golf.
The prior art made chipping the golf ball almost impossible to do as described above which forced many players to forget about the game. Therefore, another object of the method and device of the invention is to provide the player with a device that will help him or her to do a more controllable and more precise chipping of the golf ball.
The prior art made it very hard for the golf player to do his or her putting. It is very hard for the player to line up the swinging action of the Putter and hit the ball to go into the direction of the ball if he or she does not practice such a swinging action several times before he or she does it. Therefore, another object of the method and device of the invention is to give the golf player a more perfect swinging way to do his putting.
The prior art of swinging sports such as golf, baseball etc. has a hard time attracting young people to join the sports, because it is difficult to play and not exciting to make them want to play it. Therefore, another object of the method and device of the invention is to make the game more exciting for the young people to join the sport, and we make the swinging sports more popular.
The prior art made many players of swinging sport hopeless to achieve any progress in their training or playing the games to become professional one day. Therefore, another object of the new method and device of the invention is to give such players a new hope and make them reach a higher level of training and playing the games.
The prior art of swinging sports such as hockey made the players crash into each other or crash each other to the wall when playing the game resulting in many injures, Therefore, another object of the method and device of the invention is to soften the crash between the player, stopping them from harming each other and make hockey a safe game to play for adults and specially for kids.
The prior art made the players of swinging sports such as tennis, racquetball, and squash etc. hit the ball with only one hand that held the racket. Hitting the ball with one hand is not strong enough especially in tennis when the player is surfing. Therefore, another object of the new method and device of the invention is to enable such players to use their two hands to hit the ball accurately whenever they like.
The prior art made the players of swinging sports such as tennis, racquetball, and squash etc. hit the ball astray whenever they held the racket with their two hands because they cannot swing the racket in the optimal swinging plane as described above. Therefore, another object of the method and device of the invention is to enable such players to swing the ball into or parallel to the optimal swinging plane when they use their two hands to hit the ball, in a perfect way, which will result in a better score and making the games more exciting to practice, and watch.

Fifth, the player will place the ruler 20 inside the ruler guide (groove or crack) 28 and make sure that the face of said club, hockey stick or bat etc. 4 is 100% perpendicular to the optimal swinging plane P by rotating said club, hockey stick or bat etc. until the face of said club, hockey stick or bat etc. becomes parallel to the ruler. Sixth, the player will close or tighten the screws of the clamping device C to keep said club, hockey stick or bat etc. fixed in its position. Seventh, the player will remove the ruler. Eighth, the right handed player will grab the left handle L with his or her left hand and grab the handle R of the club, hockey stick or bat etc. with his or her right hand and start hitting the ball or hockey puck in a perfect natural pendulum swinging way in the optimal swinging plane P with the face of the club, hockey stick or bat etc. 100% perpendicular to the optimal swinging plane P, resulting in amazing score. Connector N will not touch the player's hands during swinging because it is offset away from the handles by a safe distance X.
The player can use the preferred embodiment of the swinging device in FIG. 4 to do his or her golf chipping as follows; first, the player can choose the correct club number with the preferred tilted head angle for the distance. Second, the player will follow all the steps mentioned above in how to use the preferred embodiment of FIG. 4 to play any swinging sport and to do a perfect swing. Third, the player will step ahead to the ball. Fourth, for the right handed golf player, if the ball is in the middle distance between the legs of the player, the player will chip the ball with the tilted angle of the club head in the optimal swinging plane P. Fifth, for the right handed golf player, if the ball is located between the point of the middle distance between the player's legs and his or her right leg, in other words the ball will be located near or facing the right leg of the player, the player will chip the ball with the a tilted angle less than the club head tilted angle depending on how far the ball from the player's right leg in the optimal swinging plane P. Sixth, for the right handed golf player, if the ball is located between the point of the middle distance between the player's legs and his or her left leg, in other words the ball will be located near or facing the left leg of the player, the player will chip the ball with the a tilted angle more than the club head tilted angle depending on how far the ball is from the player's left leg in the optimal swinging plane P. This will provide the player with a better opportunity to chip the ball with any angle he or she likes and not limit the player to the choice of chipping the ball with the club angle as the prior art, as if we provided the player with a golf club set consisting of unlimited number of golf clubs. This will make chipping the ball in golf not only accurate fun and precise, but also will increase the score. This will take away the frustration of chipping the ball in golf, make the player chip the ball accurately and make the game easy to play and practice. This will also enable the player to use fewer clubs to play golf because he does not need all of the standard clubs used for the prior art since he can control the tilting angle to hit the ball with the same club as we described above.

Third, the player will step ahead to the ball. Fourth, for the right handed golf player, the player will have the choice of placing the ball in the middle of his or her two legs, near or facing his or her right leg or near or facing his or her left leg. We found out that we prefer that the right handed player place the ball very near or facing the edge of his or her left leg to do his or her putting. This will allow him or her to almost be behind the ball, which will make him and her shoot the ball in the direction of the hall. Fifth, using the invention device will enable the player to practice the swing several times before he or she shoots the ball. The player can step ahead to the ball and start swinging the putter up and down in a pendulum way until he or she feels comfortable about the direction and the force of the swing. Sixth, the player can finally with a last swing will hit the ball and make it go straight into the hall.
