WO2015002112A1 - Table tennis racquet grip - Google Patents

Abstract

The first embodiment (100) in Figure 1 is an embodiment showing an example of a flare-type grip in which the grip is provided with a projection (108) on which to hook the thumb. The flare type is a popular type used by 60% of table tennis players. The grip effects of hooking the thumb on the projection (108), which serves as a support, are that: the grip can be loosely grasped because tight gripping is not necessary; instantaneous changes in racquet inclination during a game in response to balls returned from a competitor can be easily handled; and due in part to the effects of the weight of the rubber (104, 105), the effects of the rotational and centrifugal forces, which use the projection (108) as a fulcrum and utilize the size of the gap between the racquet grip and the palm of the hand, also act synergistically to manifest a strong driving effect.

Description

[Name of invention determined by ISA based on Rule 37.2] Table tennis racket grip

In this invention, by providing a projection on the thumb that can be utilized in a shake hand of a table tennis racket, it becomes possible to loosen the handwork of the grip with this projection as a fulcrum, and the racket during the swing due to the action of the gap generated in the grip and palm The centrifugal force effect can be used with the rotational force generated by gravity, and the hand is driven by the synergistic effect by removing the little finger and using the bending of the wrist, and the hand effect that combines the prevention of falling off the thumb It is related to the grip which pursued.

The table tennis racket shake hand grips are mainly “straight” ST, “flare” FL, “conic” CO, and “anatomic” AN. The ratio used for straight and flare accounts for 90%.

It is difficult to determine the grip shape, which is optimal for attacks and defenses, and it is often decided from the above grip shapes according to the feeling of each individual.

“Straight” T, about 30% of people are using this type with a straight grip, and there are products with only a straight grip in the cutman racket.

"Flare" FL, which is the most commonly used type, is said to be used by about 60% of table tennis enthusiasts as it spreads toward the end of the grip.

"Conic" CO, the end of the grip has a wider hem as in "Flare", while "Flare" has a curved hem and "Conic" is straight and even. Differing points.

“Anatomic” AN is a type in which the center part of the palm is swollen, and few people use it.

The straight ink line looks similar to a straight line but increases in thickness as it approaches the edge of the grip, and is generally not well recognized and has limited users.

Tenaries are sold with unique grips that are bent in accordance with the shape of a person's hand, and there are other pistol-type grips.

Each competitor selects and uses these grips according to the feeling, but there are no restrictions on the shape and design of the grips, and each individual performs processing such as scraping a part according to the grip feeling. Remodeling according to the ring is also made and used.

Using the grips that each person feels like, the ball speed increases as you improve, and there is a lot of changing balls, and in order to respond to this, you are competing how to grip to change the angle of the racket instantly It is difficult to respond to this.

Depending on the type of ball returned from the opponent, if you change the way you hold it, it may fall off. For this reason, the faster the ball speed, the more driving and the number of changing balls, the stronger the grip part will be held during the competition.

The grip part should be strengthened only at the moment of rebounding the hit ball, but it can be returned by changing the grip according to the change of the hit ball to loosen the grip according to the speed of the hit ball, but the ball speed is in time Absent.

For this reason, the speed of the ball is fast, it is not possible to respond to the ball returned to the changing ball, it is not possible to return to a place where the course of the hit ball is off.

Therefore, it is difficult to always hold the grip strongly and change the racket angle according to the change.

When it is required to always hold the grip strongly and turn the ball of the changing ball or the fast ball at an angle, an excessive burden is imposed on the wrist to support it, and fatigue is promoted.

As described above, existing grips have their own characteristics and are used in competitions, but because they hold the grips strongly, it is difficult to deal with changing balls, fast balls, etc. Return balls cannot be returned easily.

It is difficult to strike back at the optimal racket angle with a grip that is strongly gripped by the changing ball that comes back, and it will return a ball that is advantageous to the opponent.

It is not easy to predict the course and place of the fastball and the changing ball that are returning, but it is important to keep the grip loose so that it can always respond to any correspondence.

The time to return the ball from the opponent after playing it is not necessary to grip the grip, but rather to loosen the grip to change the angle of the racket according to the return, as described in [0019], Instant response is possible.

As described in [0012], since the grip has nothing to support the grip with a loose grip, it falls off as described in [0012].

As the rally of the competition continues to prevent falling out, the grip strength of the grip becomes excessive on the wrist as described in [0016] in order to respond to the return ball type by changing the angle of the wrist without loosening. The burden is increased and fatigue is accelerated.

The relationship between the racquet and the wrist with the grip firmly held and fixed is to support the returned drive, fast ball, and changing ball by turning the wrist to cope, but the racket rotation is limited to the wrist bending angle For this reason, it is difficult to return a ball in the vicinity of the net, and the player hits the net and does not reach the opponent's court. In order to avoid this, the opponent has an advantageous return and invites the opponent's smash.
In order to solve the above-mentioned problems, a completely new type of grip hand method that does not exist is necessary.

The speed of hitting for beginners of table tennis is not as fast as that of advanced players, and it is limited to driving and changing balls. If you do not solve the problem, you will not be able to respond to the hit ball that is returned, one is that the grip is always held firmly and close, and the wrist is overburdened, and basically it will not correspond .

Therefore, it is necessary to avoid gripping the grip strongly in order to always return the return ball from the opponent in an advantageous manner. To this end, it is important to hold the grip firmly only at the moment of rebound and hold the grip gently until the opponent hits it.

A grip that is gently grasped causes a recent double-sided rubber racket to fall off from the hand, so that the problem is solved by using a projection on the thumb as shown in FIG. 1/7.

The projection provided is not only effective in preventing the above-mentioned dropout, but it is also possible to easily grip the moment when the ball is rebounded without the need to always hold the grip by simply placing the thumb on the projection. Realize.

Although there is a slight difference in how to put the thumb depending on the feeling of each individual, the grip state is shown by way of example 7/7. As shown in FIG. As shown in the figure, a gap is formed as indicated by the dotted line portion A, and the angle of the racket can be changed instantaneously as it progresses, and various return balls can be handled.

The relationship between this grip and the gap between the palms always changes the angle of the racket according to the grip that is gripped in response to the return ball, and it takes an excessive burden on the wrist, but the grip that is not gripped changes the angle of the racket Can be easily done, and overburdening the wrist can be solved.

When the ball is rebounded as it progresses, the grip hand is loosened instantly, the centrifugal force acts according to the weight of the racket around the protrusion, and the gap between the grip and the palm acts only on the dotted line shown in Fig. 7. It is possible to make the return ball advantageous to the projection effect provided.

Although there are individual differences, there is a distance of about 70 mm from the thumb to the wrist, and when the ball is flipped back, the grip of the grip is loosened to move the little finger away from the grip, so the rotation angle of the racket increases and drives to the return ball It is easy to follow through and can produce a synergistic effect with 70mm.

The back swing has a prominent projection effect, and because the swing is inherently weak, famous players in tennis also use both hands to return the ball, but table tennis is also the same, the swing effect is weaker than the fore swing, improvement As a result, the wrist is excessively burdened, but the grip is loosely gripped by the thumb hanging on the protrusion, and as shown by the gap zone in FIG. In addition, the rotation effect of the racket can drive the ball and compensate for the weak swing.

When a fast ball is returned to the front of the body from the opponent, which is said to be a weak point, the return ball that is rebounded often has a weak ball power and is advantageous to the opponent, but this is a result that depends on the wrist without a margin for grip This projection effect allows the grip to be held loosely, so that the angle can be instantly changed according to the ball type and speed of the return ball, and an advantageous return ball with drive is possible.

Returning the ball when the ball passes the net or is lower than the net requires a technique, but the angle of the racket can be freely changed, so that it is possible to easily return the returned ball to the opponent's court.

The same is true for the cut swing. Grab the grip with a strong effect only when it is loosely gripped and flip it back. Can generate a counter-rotation and return an opponent's disadvantageous ball.

Advanced table tennis players do not always hold their grips and do not play against each other, hold them as loosely as possible, hold them back instantly, and use the arm and wrist scenario to maintain the balance of the whole body. This can be realized from the beginner's stage by providing a thumb-hanging projection, and it becomes possible to compete without dropping the racket with a loose grip.

The protrusion on the thumb hook creates a gap between the grip that grips loosely and the palm, creating a rotation effect of the racket with the protrusion as a fulcrum and creating a drive effect on the hit ball, which is a smash that also drives the cut service used in competitions Attack is also possible.

The grip, which can always be held loosely, can instantly handle the racket at the optimum angle to various return balls from the opponent.

Originally, the backswing has a shoulder, arm, and wrist structure, so that the hitting ball is weaker than the fore swing, but a strong hitting ball can be returned by the synergistic effect of the rotational centrifugal force effect of the racket with the wrist scenario and protrusion as the fulcrum.

The response of hitting balls lower than the height of the net has the effect that the racket can be played at the optimum angle instantly by the projection effect that allows a loose grip with a margin, and the hitting ball that is advantageous to the opponent's court can be returned.

When the opponent's fastball is returned to the front, the grip that can be gripped loosely by placing the thumb on the protrusion can instantly make the racket the optimal angle, and the protrusion provided using the distance between the grip and the palm Rotating the racket with the fulcrum as a fulcrum, you can drive the hit ball and return to the opponent.

The projection provided on the grip of the present invention can easily change the angle of the racket by holding the side of the projection with the thumb instead of hooking the thumb as shown in FIG. It is also characterized by creating an effective grip hand that can hit the opponent's weak point court with a fore swing.

Embodiments of the Invention

Hereinafter, an embodiment according to the invention of a grip effect with a projection on a thumb of a table tennis racket will be described with reference to the accompanying drawings.

(First embodiment)
Drawing 1/7 100 according to the first embodiment of FIG. 1 is an embodiment showing an example of a flare type in which a protrusion for giving a thumb is attached to a grip, and the flare type is a popularity used by 60% of table tennis players. It is not necessary to grip the grip effect of hanging the thumb on the supporting 108 projections, which makes it possible to grip the grip loosely and change the racket inclination angle during competition against the return ball from the competitor In addition, instant response is easily possible, and there is a weight effect of 104 and 105 rubber, and a rotational centrifugal force effect using the distance between the grip of the racket and the palm using the projection of 108 as a fulcrum synergizes. Demonstrates a strong drive effect.

There is no need to squeeze firmly by placing a thumb on the projection of 108, and there is also a weight effect of the rubbers 104 and 105. When the gap formed between the palm and the grip swings on the hand with the projection of 108 as a fulcrum, Rotate by a distance, and a strong driving effect is born on the hit ball, and the hit ball is advantageous to the opponent.

The above effect is also remarkable in the backswing. By improving, the hand effect grasped loosely against the return ball from the opponent can be exhibited, and the back smash can be determined.

An example of a hand that can be used to hold a loose hand even on a cut swing is shown in Fig. 7/7. Fig. 7 shows an example of a hand, but the rotational centrifugal force effect of a racket with a projection as a fulcrum is synergistic with the wrist flexion. The effect works and creates a stronger cutting force, making it difficult for the opponent to hit the ball and hitting it.

The 108 protrusions can be processed according to the individual grip hand feeling of each competitor, and the optimum fitting can be utilized in the competition.

(Second embodiment)
FIG. 3 is an embodiment showing an example of a straight type 200 in which a projection with a thumb on the grip is applied, according to the second embodiment. The straight type is a popular second grip used by 30% of table tennis players. It is said that it is used for cut swing.

The features and advantages of the grip with the thumb hook are the same as the flare type shown in Figure 1/7, but the grip end is not straight but straight, and even old enthusiasts are good. As described in the flare type mentioned above, the fact that holding the ball only momentarily when it hits the ball corresponds to various return balls from the opponent.

The way to hang the thumb on the protrusion differs depending on the feeling of each individual player like flare, but the reverse rotation power of the ball of the cut swing is the centrifugal force effect due to the rotational movement of the racket with the protrusion as a fulcrum. 7 As shown in FIG. 7, the distance between the grip and the palm is realized.

As described in [0054], the hitting force of the hitting ball caused by the rotational movement of the racket centering on the protrusion can exert an effect when the ball bounces on the opponent's court as well as the drive effect of the fore swing.

(Third embodiment)
FIG. 6 is a view showing an example of a third embodiment in which a thumb hook projection is provided on the grip of the present invention. This is a grip type in which the direction of thickness is curved in the flare type and the grip end is widened. is there.

As described above, the optimal feeling of fit for each competitor is important for the grip feeling. However, the third embodiment is suitable for swinging strongly, and it is suitable for explaining the grip shown in FIGS. This figure shows the grip of the third embodiment selected.

Although the degree of thumb hanging on the grip depends on the individual fit of the competitor, an example is shown.

By drawing the curve shape up to the grip end and making it thicker, the feeling of stability may be effective for the competition by the athlete, but there may be some athletes who feel uncomfortable, but as mentioned above, the athlete It is also possible to process to fit the feeling.

(Fourth embodiment)
FIG. 5 shows an example of providing a grip that can be attached to a grip of a racket used by each competitor in accordance with the feeling of each competitor.
