Description

Technical Field

[0001] The invention relates to a table tennis racket, in particular to a handle of the table tennis racket. Background Art

[0002] At present, table tennis rackets can be roughly divided into three types, one is the straight grip table tennis racket (hereinafter referred to as "straight grip"), one is the horizontal grip table tennis racket (hereinafter referred to as "horizontal grip"), and one is the gun-style table tennis racket (hereinafter referred to as "gun racket") that has appeared in recent years. The handles of the straight grip and horizontal grip extend vertically upward with the longitudinal axis of the racket; the gun-style racket handle extends from the center point of the upper part of the racket to the rear and downward, and there is also a vertical straight grip handle on the handle, and then a horizontal grip handle extending horizontally at a 90-degree angle to the racket, but no matter which type, the handle is extended from the center position of the upper part of the racket to the rear section of the handle.

[0003] In the straight racket, the user holds the racket handle with the thumb and index finger, and the middle finger, ring finger and pinky finger press against the back of the racket. This grip position is low, and the racket fulcrum is close to the center of the racket, which can maximize the combined force of the body, arm and wrist directly transmitted to the racket, with strong hitting force, suitable for close-range fast attack.

[0004] However, the structure of the human hand is that the thumb faces in one direction, and the other fingers face in the opposite direction of the thumb. When holding the racket with a pen-hold grip, the index finger moves upward from its natural drooping position, around the back of the racket to the front, and clasps the handle together with the thumb. With this grip, the index finger becomes an obstacle when hitting the ball backhand, such as back-drawing or pushing. It limits the range of wrist rotation, and the wrist cannot do anything about the ball that exceeds the axial rotation range of the wrist. Therefore, when using a pen-hold grip, a lot of force must be used to force the athlete's backhand wrist to flip to the maximum.

[0005] In addition, when hitting the ball backhand, the return ball needs to be pressed down to prevent it from flying off the table, so the arm needs to be raised inward. The higher the return ball bounces, the higher the arm needs to be raised inward. However, the internal rotation of the arm is also limited in amplitude, so the situations suitable for backhand driving and pushing are limited, and it is only suitable for balls with a low bounce height. Backhand is the weakness of pen-grip players. Pen-grip backhand is a style of play that has to be adopted out of desperation. When using it, its racket face can only be turned forward to be parallel to the ground or slightly above it, and the body even has to cooperate by leaning forward. It is difficult to do a backhand kill with an upright body posture.

[0006] The pen-hold grip also limits the role of the index finger. In the case of a pen-hold grip, the index finger has no other active role except for holding the racket.

[0007] In the history of table tennis in my country, there was an athlete named Zhang Xielin. In order to overcome the above-mentioned shortcomings of the pen-hold racket, he placed his index finger on the back of the racket and pinched the racket with his thumb and index finger to play. Some people call this grip a knife. Although this solves the problem of locking the wrist joint when the index finger is wrapped around the front, this grip does not hold the racket tightly enough, and when smashing the ball hard, the racket is easy to slip out of his hand. Therefore, Zhang Xielin's main way of playing is to slice the ball. The knife grip sacrifices the powerful smash of the pen-hold racket.

[0008] Although the straight racket is suitable for fast attacks close to the table, when hitting the ball, whether it is forehand or backhand, you need to swing your arms widely. It is difficult to attack the ball that does not go beyond the table, the ball that is close to the table or the ball that is chasing the body without enough space to swing the arms. You can only rub the ball or push it, and the force of rubbing or pushing the ball back is weak.

[0009] The flexibility of the wrist of a pen-hold racket is affected. When hitting the ball with a pen-hold racket, the wrist cannot move randomly and must be kept straight, so that the racket and the ground maintain a specific initial angle. This is the hand shape. The pen-hold racket hand shape does not make use of the wrist.

[0010] There are also the following disadvantages of straight shooting:

[0011] Theoretically, when a penhold racket hits the ball with its forehand, the racket face can be turned from facing up to facing down until it is parallel to the ground, so that the force of the ball is maximized. However, because the hand shape is fixed at a specific initial angle (45 ͦ angle), when the forehand flips forward from the initial angle, at least half of the space for movement is sacrificed. The maximum turning range of a human hand should be 180 ͦ angle. In other words, the palm of a person can flip from 0 ͦ angle facing up to 180 ͦ angle facing down. If the racket face can be consistent with the rotation range of the wrist, the range of the ball can be greatly improved. In table tennis, the greater the rotation range of the racket, the greater the force of the ball, and the stronger the control of the table tennis ball. The turning range of the penhold racket hand shape is limited, so the power of its attack and smash, especially the backhand power, has an insurmountable ceiling; also due to the limitation of the turning range of the penhold racket hand shape, the arc spin ball pulled by the penhold racket is not as good as that pulled by the horizontal racket.

[0012] When the player holds the racket with his hand, the index finger and thumb enter the rubber part of the front of the racket, and the other fingers enter the rubber part of the racket from the back of the racket. When playing, the table tennis ball often hits the index finger. This problem has existed since the first day of the birth of the pen-hold racket, but it has not been solved yet.

[0013] When hitting the ball forehand and backhand with a straight racket, the thumb cannot use force; when hitting the ball backhand with a straight racket, the index finger, middle finger, ring finger and little finger cannot use force.

[0014] What finally sent the penhold racket to the history museum was the rise of the era of arc spin in table tennis. The penhold racket backhand could not suppress the spinning arc spin.

[0015] Due to the above-mentioned shortcomings of the pen-hold racket, fewer and fewer people use the pen-hold racket, so the horizontal racket, also known as the broadsword racket, has become the mainstream of table tennis rackets today.

[0016] When using a horizontal racket, the user holds the racket handle with the entire palm and five fingers, and can easily use both sides of the racket. When using a horizontal racket, the user can exert full force in the middle and long distance, with a wide surface for catching the ball and a strong attack.

[0017] However, when the racket is held horizontally, the end of the racket is raised at an angle of about 45 degrees, so the wrist needs to be hung to hit the ball. Hanging the wrist means that the axis of the horizontal racket is at an angle of about 45 degrees with the arm holding the racket. When hitting the ball, the arm and wrist need to be raised and the angle of the wrist needs to be changed according to the situation. In this case, the horizontal racket must be forced to make complex wrist corrections every time it hits the ball. In table tennis, a special, ever-changing, and extremely high-speed sport, it is extremely difficult to accurately correct the optimal position of the wrist in a very short time. This shortcoming of the horizontal racket forces the athletes to retreat to the middle or far table and hit the ball at the point where the table tennis ball falls, so as to give the athletes sufficient time to adjust the position of the wrist. However, the winning magic weapon of table tennis is fast attack, and the best hitting position for fast attack is at the rising point of the rebound of the table tennis ball. When hitting the ball at the point where the table tennis ball falls, it can only be handled by pulling or slicing. Pulling or slicing the ball will result in weak return force.

[0018] When holding a table tennis racket, the direction of the palm is generally called the front of the hand, and the direction of the back of the hand is called the back of the hand. When playing a horizontal forehand, the hand is in front and the racket is behind; when playing a horizontal backhand, the racket is in front and the hand is behind. Everyone in the table tennis field knows that when the hand is in front, the hand leads the racket, and the playing stability is good, while when the hand is behind, the racket leads the hand, and the playing stability is poor. The accuracy of the landing point of a horizontal backhand pull is close to that of a straight racket push, and the error rate is much higher than that of a forehand. Therefore, a horizontal backhand can only be mainly sliced. Although slicing the ball can reduce the probability of the return ball going out of bounds, the slicing speed is slow and does not pose much threat to the opponent.

[0019] The forehand and backhand of the horizontal racket need to swing the arm widely when hitting the ball. The greater the arm movement, the higher the rotation of the arc ball, and the greater the power of the smash. Therefore, for the non-table balls, short balls near the table and chasing balls that do not have much room for arm swinging, the horizontal racket is more difficult to handle than the straight racket.

[0020] The flexibility of the wrist is also affected when playing with a horizontal racket. Like the vertical racket, the horizontal racket mainly relies on swinging the arm to play. In order to ensure that the racket face and the ping-pong ball are at a specific angle when hitting the ball, the racket face must maintain a certain initial angle when playing. For this reason, the wrist cannot be relaxed and must remain stiff.

[0021] In addition, there are some other disadvantages of horizontal shooting:

[0022] Ping-pong and tennis are both called "tennis" in English, but ping-pong is called "table tennis". The table area is much smaller than that of a tennis court. It is more difficult to accurately control the landing point of the ball and hit a larger return angle when it is far away from the table. For table tennis, retreating to the middle or far table is a last resort, a defensive and passive move, and not a necessary tactic for table tennis. The tennis court is open, and standing at the baseline to pull can make full use of the length and width of the court and mobilize the opponent, which is the main tactic of playing. Therefore, pulling from the middle and far table is not the strength of table tennis, but the specialty of tennis.

[0023] Whether it is forehand attack or backhand loop, the horizontal racket cannot use any strength in the fingers. In table tennis, in addition to using the power of the arm swing, it is also very important to use the power of the fingers, especially when playing fast balls and heavy smashes. This shortcoming of the horizontal racket also hinders the development of horizontal racket playing.

[0024] There are some other disadvantages of the horizontal racket, which are not listed one by one. The above-mentioned disadvantages alone are enough to show that the horizontal racket cannot lead the sport of table tennis to continue to move forward.

[0025] In order to overcome the shortcomings of the above two grips, a "gun-style table tennis racket" has emerged in recent years. Figure 1As shown, Chinese patent CN 92243422.0 intends to take advantage of the flexible and fast characteristics of a pendulum racket and the advantages of a horizontal racket in that it can take the wide ball and attack the ball fiercely. A pendulum grip (3) perpendicular to the racket and a horizontal grip (4) that is folded 90 degrees with the pendulum grip (3) and extends horizontally are specially provided. An index finger hole (7) is dug out in the upward extension of the racket outside the junction of the pendulum grip and the horizontal grip handle, so that the index finger passes through the finger hole and clasps the vertical pendulum grip (3) together with the thumb. This is basically the same as the pendulum grip of a racket, except that the middle finger, ring finger and little finger do not rest on the back of the racket, but pass through another large hole (6) dug out in the upward extension of the racket and are horizontally gripped on the horizontally extending horizontal grip handle (4). Although the racket of this structure can be used as a pendulum grip for forehand and as a horizontal grip for backhand. However, the advantages of either grip cannot be fully realized by this kind of compromise. For example, when using a pen-hold racket, since most fingers (middle finger, ring finger and pinky finger) are held on the horizontal grip, instead of against the back of the racket like a traditional pen-hold racket, the grip position is high (a high grip position, or high hand position, means that the hand holding the racket is far from the racket, on the contrary, the hand holding the racket is close to the racket, which is called a low hand position), and is far from the center of the racket. Therefore, the combined force of the legs, waist, arms and wrists cannot directly act on the center of the racket closer to the hitting point through the fingers against the back of the racket like a traditional pen-hold racket, but is first transmitted to the horizontal grip (4) away from the center of the racket, and then transmitted through the horizontal grip (4) to the vertical grip (3) also away from the center of the racket, and then dispersed from the point where the vertical grip (3) connects with the racket to the racket face. Since the path of force transmission is too long and there are too many links, it is indirect transmission, and the hitting force is greatly reduced.

[0026] In addition, when the racket is used as a horizontal racket, the thumb and index finger holding the pen-hold handle not only cannot help adjust the angle of the racket, but because the direction of action of the thumb and index finger is inconsistent with the middle finger, ring finger and little finger, it becomes an obstacle to the hitting force.

[0027] In order to bring out the power of forehand straight racket close to the table, the athlete should stay close to the table, and in order to bring out the backhand horizontal racket, the athlete should retreat to the middle or far table. When using this kind of gun racket with forehand, the athlete must rush to the close table, and when using the backhand, the athlete must immediately retreat to the middle or far table. In a very short moment, the player is moved up and down, regardless of whether the athlete can do it. Even if he can, the player will fall into a passive position and be exhausted by repeatedly moving the player up and down, and he will not be able to exert his tactical conception and competitive level at all. It is difficult to say that this racket has any practical advantages. Although the above-mentioned gun racket allows the racket to be changed at any time in the two playing styles, the disadvantages are enough to offset the advantages.

[0028] In addition, when playing, you need to use your brain. Before hitting the ball, you need to think about how to hit the ball, whether to use the forehand or the backhand, and which part of the racket to hit the ball. All of this must be planned in advance, and the position and strength of the racket touching the ball must be guided and controlled by the mind. The hand position of the above-mentioned pistol racket is high, and the hand axis and the arm axis are not in a straight line, so that the center of gravity of the handle deviates from the center of the racket, as if holding a racket and hitting the ball horizontally left and right. This not only makes the ball weak, but also loses the feeling of the hitting point, and the position of the racket touching the ball cannot be controlled by the mind.

[0029] The above-mentioned gun racket, like the straight racket and the horizontal racket, still cannot solve the problems of chasing balls, short balls on the table, and smashing balls close to the table.

[0030] The thumb and index finger of the above-mentioned pistol racket are held on the handle of the pen-hold racket, so it is difficult to exert force when backhand slicing and pulling the ball.

[0031] When using the above-mentioned pistol racket to hit a forehand or backhand loop ball, the thumb cannot be used to exert force; when hitting a forehand straight ball, the thumb cannot be used to exert force; and when hitting a backhand straight ball, the index finger cannot be used to exert force.

[0032] The common disadvantage of the above three rackets is that they cannot give full play to the flexibility of the athlete's wrist and the strength of the fingers.

[0033] The above three rackets do not have a handle that fits the fingers and palm naturally.

[0034] Chinese patent No. CN111388973B provides a table tennis racket that better solves most of the problems of the above-mentioned penhold racket, horizontal racket and gun racket, and is named "finger racket".

[0035] The finger racket of the patent has a thumb hole, an index finger hole, a middle finger hole, and a horizontal handle extending backward from the center of the upper edge of the racket.

[0036] The problem with this finger racket is that the finger hole only serves to hook the racket, but does not provide a fulcrum for the middle finger to exert force and play the role of adding force and controlling the angle of the return ball.

[0037] The middle finger hole of the patent only hooks the racket but cannot stabilize the racket. The racket may shake due to the matching gap between the middle finger hole and the middle finger.

[0038] Although the patented handle has a turn extending from the base of the thumb upward to the wrist, which interacts with the turn at the end of the horizontal handle to stabilize the racket to a certain extent, the extension lines of the two turns are not on the horizontal and vertical axes of the racket handle. Therefore, the design of the turn of the patented handle is not perfect for stabilizing the racket.

[0039] The patented handle does not have a mechanism for stopping in the longitudinal direction, which makes it less stable in the longitudinal direction.

[0040] This patent fails to completely solve the above-mentioned problem of high hand position and poor force transmission due to gun clapping.

[0041] This patent fails to completely solve the problem that the racket is not good at guiding the hitting position. Summary of the invention

[0048] The invention provides a table tennis racket with a wider connecting surface between a handle and a racket face.

[0049] The invention provides a table tennis racket which is convenient for guiding thoughts.

[0050] The table tennis racket of the present invention has a blade and a three-dimensional handle. The three-dimensional handle of the present invention is like a ball of cotton held in the palm of the hand, and the cotton forms a three-dimensional racket handle according to the shape of the hand. The three-dimensional racket handle has a tiger's mouth notch, and the tiger's mouth notch is arranged on the upper edge of the right side of the three-dimensional handle; a thumb hole or thumb notch, and the thumb hole or thumb notch is arranged on the right side of the three-dimensional handle, at the position where the thumb is naturally bent and gripped, and the front finger of the thumb extends out of the thumb hole or thumb notch; an index finger hole, and the index finger hole is arranged on the right side of the three-dimensional handle, at the position where the index finger is naturally bent and drooped, so that the front finger of the index finger passes through, and the vertical extension line of the index finger hole points to the upper part of the racket; a middle finger hole, and the middle finger hole is arranged in the middle of the three-dimensional handle, at the position where the middle finger is naturally drooped, so that the first knuckle of the middle finger passes through, and the middle finger hole is arranged at ... The vertical line is consistent with the vertical center line of the racket; a middle finger pocket for accommodating the first knuckle of the middle finger, the middle finger pocket is arranged in the middle of the three-dimensional handle and the upper part of the middle finger hole; a middle finger sleeve is in a half-moon shape and is arranged outside the first knuckle of the middle finger; a top ridge is arranged outside the middle finger hole and at the connection between the second knuckle and the third knuckle of the middle finger, the top ridge is bonded to the lower edge of the middle finger hole of the handle; a horizontal handle, the horizontal handle is 90 degrees folded with the three-dimensional handle longitudinally and extends horizontally to the left, the ring finger and the little finger hold the horizontally extended horizontal handle from the bottom of the horizontal handle, which plays the role of holding the racket handle and balancing the overall handle and stabilizing the rudder. Among them, the present invention extends downward from the outer extension of the tiger's mouth notch to the connecting part of the racket, and a plurality of holes are arranged at the connecting part extending downward from the outer extension of the tiger's mouth notch to the racket. The functions of the plurality of holes are to reduce the air resistance when playing and to reduce the weight of the racket handle.

[0051] The connection between the handle and the racket of the table tennis ball of the present invention extends from the middle of the upper edge of the racket to the right to a position parallel to the upper edge line of the racket surface. The connection between the racket and the handle of the table tennis racket of the prior art is extended upward from a point in the middle of the upper edge of the racket. The handle of the pistol racket is turned at the end of the traditional upwardly extending handle and extends horizontally backward to form a horizontal handle, but the connection between the handle and the racket is only one point. The force of the palm, arm and body is transmitted to the surface of a racket through a point. The connection point is like a force resistance valve, which hinders the transmission of force. This is like a thin neck with a big head, the head is heavy and the feet are light, and the light point drives the heavy surface. Obviously, the force will be lost at this point. And the farther the hand holding the racket is from this point (referred to as high hand position in the art), the more the force transmission is damaged. Among the above three prior art rackets, the straight racket hand is closest to the racket, followed by the horizontal racket. The distance between the index finger and thumb of the pistol racket and the racket is similar, but the other fingers leave the racket and hold on the horizontal handle, so its hand position is the highest and farthest from the racket. The invention changes the connection part between the handle and the ball board from a point to a surface, thus overcoming the loss of force at the connection point.

[0052] The handle of the racket of the present invention is made into a three-dimensional shape that naturally fits the palm, fingers and base of the thumb according to the way the palm naturally holds an object.

[0053] The base of the racket handle of the present invention has two extensions, which extend along the inner and outer sides of the thumb. The upward extension part that fits between the base of the thumb and the thumb is called the base of the base of the thumb; the part that fits the extension of the thenar of the palm (bend muscle of the thumb) is called the inner extension part of the base of the thumb. The base of the base of the thumb extends to the root of the thumb, and the inner extension part of the base of the thumb extends upward along the thenar of the palm to the inner root of the thumb. The inner extension part of the base of the thumb goes around the back of the thumb and forwardly engages with the outer extension part of the base of the thumb to form a thumb ring-shaped thumb hole, or the inner extension part of the base of the thumb does not engage with the outer extension part of the base of the thumb, but only forms a "C"-shaped gap for placing the thumb. The inner extension part of the base of the thumb is extended horizontally to the lower part of the palm near the wrist, and a longitudinal axis stop block is arranged at the end to prevent the racket from sliding upward. The longitudinal axis stop block is arranged in the concave part between the thenar and the hypothenar on the inner side of the palm.

[0054] The racket horizontal handle of the present invention may further include a horizontal axis stop block, which is arranged at the end of the horizontal handle and abuts against the outside of the little finger to prevent the racket from sliding in the horizontal axis direction.

[0055] The longitudinal axis stopper and the transverse axis stopper of the present invention can be in the shape of a square or a sphere, preferably a sphere. In one embodiment of the present application, the side of the stopper that contacts the palm inward is a semicircular shape that protrudes inward, and the part that does not contact the palm is a concave shape to reduce the weight of the racket handle.

[0056] The horizontal handle of the present invention is a part extending horizontally from the middle of the vertical handle to the left side. The shape of the horizontal handle of the present invention can be cylindrical or strip-shaped, and the thickness of the horizontal handle should be suitable for the ring finger and the little finger to hold tightly.

[0057] The middle finger socket and the middle finger sleeve of the table tennis handle of the present invention provide a fulcrum for the movement of the middle finger. When the first joint of the middle finger is pressed inward, the joint of the second joint of the middle finger will press forward the top ridge set at the lower edge of the middle finger hole, and pressing the top ridge forward will push the racket to move forward accordingly. The force generated by the second joint of the middle finger pressing the top ridge can be combined with the force of the palm, wrist, arm, waist and legs to increase the hitting force. The action of the middle finger joint pressing the top ridge may seem small, but the explosive force generated by the small action bursting out instantly is very large. Just like the sudden push in Tai Chi push hands, although the movement amplitude is very small and almost imperceptible, it can push the opponent out several meters or even more than ten meters. In addition, the middle finger joint pressing the top ridge can also link the racket to change direction and increase the angle of the return ball. Moreover, the action of the middle finger joint pressing the top ridge is very small and concealed, and is not easy to be discovered by the opponent.

[0058] The vertical extension line of the middle finger socket of the table tennis handle of the present invention is consistent with the vertical center line of the racket and points to the center point of the racket. When the center part of the racket is used to hit the ball, the vertical extension line of the middle finger socket is consistent with the vertical center line of the racket, and it is easy to find the center point of the racket with the middle finger socket as a reference system. In the case of the above-mentioned gun racket, there is no middle finger hole and middle finger socket pointing to the center point of the racket, and it is difficult to imagine the position of the center of the racket with the mind. The setting of the middle finger socket is conducive to the guidance and control of the mind when playing.

[0059] The vertical extension line of the index finger hole of the table tennis handle of the present invention is consistent with the vertical midline of the upper half of the racket, and points to the center point of the upper half of the racket. When pulling an arc, it is generally hoped that the center part of the upper half of the racket will contact the ball so that the ball can roll and rub on the racket surface for a longer distance. The longer the distance of the ball rolling and rubbing on the racket surface, the more the arc spin ball will turn. With the position of the index finger hole as a reference coefficient and guidance, it is easy to imagine the center point of the upper half of the racket. The setting of the index finger hole is conducive to the guidance and control of the mind when playing the ball.

[0060] In the present invention, the user passes the index finger and the middle finger through the index finger hole and the middle finger hole respectively, and hooks the lower end of the handle from the lower part of the handle. The user uses the longitudinal axis stopper block of the notch of the thumb to press the racket from the upper part to slide upward, one up and one down, so as to prevent the racket from shaking in the longitudinal axis direction; the user limits the front end of the racket handle through the thumb, the notch of the thumb and the thumb hole, and limits the rear end of the racket handle through the anti-slip stopper block at the terminal of the horizontal handle, one front and one back, to prevent the racket from sliding in the horizontal axis. The present invention stabilizes the circumferential displacement and shaking that may occur on the racket through the middle finger socket.

[0061] The racket of the present invention utilizes the natural shape of the palm and the cooperation between fingers to firmly hold the racket from multiple directions, thereby avoiding the possibility of the racket falling out of the hand when excessive force is applied.

[0062] The racket of the present invention completely liberates the wrist. The human wrist can rotate in the front-to-back direction of the palm and the back of the hand, and can also rotate in the axial direction coaxial with the forearm. When playing with a straight racket or a horizontal racket, the racket face is generally required to maintain a specific preparation angle according to the needs of the return action. In order to keep the racket face at a specific angle, the wrist needs to be adjusted to a specific angle in advance and kept fixed. When hitting the ball, the wrist is no longer moved, and the return is completed by swinging the upper arm and the forearm. Using the finger racket of the present invention, the wrist can be turned to hit the ball at the moment of contact with the table tennis ball. The wrist can be turned flexibly in the front-to-back direction or in the axial direction of the wrist.

[0063] The racket of the present invention can be used to hit the ball by swinging the arm like a traditional racket, or by swinging the wrist back and forth. Hitting the ball by the wrist does not require a large space for swinging the arm, so the racket of the present invention is particularly suitable for guarding near the table. Even if the ball does not come out of the table, near the table and the chasing ball can be handled by pulling the wrist, pulling, plucking and pushing and blocking with a small movement, and its strength is not inferior to the smash of the pen-hold racket and the horizontal racket. Because it is a smash, plucking or pushing and blocking near the table, the speed of returning the ball is very fast, and it is easy to force the opponent to retreat to the middle and far table, so as to master the initiative of playing the ball. Since the wrist is used to swing the ball, the movement is small, sudden and hidden, which often catches the opponent off guard. Since the wrist is used to swing the ball, the small rotation of the wrist can effectively change the angle of the table tennis ball, so the athlete does not need to move significantly to one side of the table to pull out the angle of the return ball, and can hit a tricky angle by standing near the table. Since the racket of the present invention can be used to swing the wrist back and forth to hit the ball, for backhand balls, the other side of the racket can be conveniently used to hit the ball, without the need for a straight-grip player to forcibly reverse the wrist and use the front side of the racket to hit the ball.

[0064] The racket of the present invention gives full play to the role of fingers. In the prior art, no matter which racket is used, the athlete's fingers must tightly hold the racket handle, relying on the friction between the fingers, palm and the racket handle to prevent the racket from slipping out of the hand under the action of centrifugal force. However, the tighter the racket is held, the more it affects other functions of the fingers in playing the ball.

[0065] In the present invention, the athlete hooks the racket with the middle finger, and the centrifugal force generated by swinging the racket is just in the opposite direction to the pulling force of the middle finger hook, so the racket handle of the present invention does not need to be held too tightly, and the grip of the racket can be appropriately relaxed to play other functions of the fingers. For example, when swinging the wrist backhand to smash, in order not to affect the swing amplitude of the wrist, the ring finger and the little finger held on the horizontal handle can be loosened a little instantaneously. Because the ring finger and the little finger are loosened, the horizontal handle of the racket can move to the outside of the palm to a certain extent. The greater the amplitude of the horizontal handle of the racket moving outward, the greater the amplitude of the racket rotating inward, and the greater the strength of the shot. When the wrist swings to the maximum limit, because the middle finger hooks the racket, the middle finger becomes the support point of the racket, and the racket, which is not restricted by the ring finger and the little finger, can still move further to the direction of the hitting point, and is not affected by the limit of the wrist. In this way, in addition to the various combined forces of the athlete's body, the inertial motion of the racket itself will also produce the effect of gravity acceleration, increasing the strength of the shot.

[0066] The racket of the present invention can be used with the thumb, index finger, middle finger, ring finger and little finger to cooperate with the wrist to make a circular motion in sequence. First, the thumb is stretched outward and inward, then the index finger is lifted upward and inward, and then the middle finger is lifted upward and inward. The ring finger and little finger also make the same motion, as if there is a round ball in the palm of the hand, and the five fingers make a ball-turning motion. The applicant named it "finger swing". Finger swing can pull out a very rotating and fast arc-spinning ball for a ball near the table, a ball that does not go out of the table, especially a low ball that does not go out of the table, and a ball that does not have room for arm swinging. Finger swing, from the point where the table tennis racket surface contacts the table tennis ball to the racket flipping to an ideal position, the rotation angle can be between 15 degrees and 180 degrees, depending on the specific ball.

[0067] For another example, the racket of the present invention uses the middle finger as the central support point and the racket handle as a lever. The slight movement of the ring finger and the little finger can change the angle of the racket, thereby hitting a ball with a tricky angle. In addition to the index finger having the effect of aggravating the smash, the slight movement of the index finger when pressing down can also change the trajectory of the table tennis ball.

[0068] The racket of the present invention not only retains all the advantages of the prior art straight racket, horizontal racket and gun racket playing methods, but also adds many varied playing methods, such as a smash playing method of swinging the wrist back and forth, a playing method of swinging the fingers, a playing method of changing the landing point of the table tennis ball by slightly moving the fingers, etc.

[0069] The racket of the present invention has a larger and heavier handle part, so that the weight of the handle and the racket is more balanced. Unlike the horizontal racket and the pistol racket in the prior art, the center of gravity always feels forward.

[0070] The racket of the present invention has a balanced center of gravity. Although the hand position is high, the feeling of holding the racket is similar to that of a penhold racket with a low hand position, and is suitable for close-range fast attack. The finger racket of the present invention is also suitable for all horizontal racket playing methods, and is suitable for long-range slices and arc spins.

[0071] The handle of the table tennis racket of the present invention can be made of wood, metal, plastic and other materials, preferably plastic material. Compared with metal, plastic material is light in weight and has strong plasticity compared with wood material.

[0072] The handle of the table tennis racket can be connected to the racket part by bonding or riveting, preferably by bonding.

[0073] The blade of the racket of the present invention can be a conventional table tennis blade.

[0074] The rubber of the racket of the present invention can be conventional rubber. The rubber on both sides can be the same or different. BRIEF DESCRIPTION OF THE DRAWINGS
