Description

The present invention relates to a table tennis racquet, and more specifically, with the racquet held in place, a thumb supports an outer portion connected to the racquet head, and an index finger is extended toward the racquet head to support the back of the racquet head. And the middle finger, ring finger and little finger extend from the racquet head so as to wrap around, but the grip is coupled so that the index finger tilts in one direction from the central axis of the racquet head so as to coincide with the central axis of the racquet head. The present invention relates to a table tennis racquet which provides a more stable hit when given by holding a grip.

In general, a table tennis racquet comprises a racquet head on which rubber is stuck on one side or both sides and a ball is hit, and a grip extending from the racquet head. A table tennis racquet of this kind is, depending on how it is gripped, a pen-holder (a structure in which a rubber is attached to one side of the racquet head) and a shake hand type (a rubber adheres to both sides of a racquet head) Can be roughly divided into two).

The pen holder type grip method is a method of pressing the front of the racket with your thumb and index finger and holding the back of the racket with your middle and ring fingers and gripping the racket grip so as to hold the pen, and it is only suitable for processing short balls Instead of being able to adjust the direction of the ball, it is possible to demonstrate fine techniques, and it is advantageous for forehand attacks, while it uses only one side, so the backhand range is narrow and it is not easy to use There is a problem that the amount of exercise is relatively large because the range of

Shake hand type grip method is a method to hold the grip of the racket to shake hands, is advantageous to the table tennis ball cut hitting method, less consumption of physical strength because it uses both sides of the racket, it is advantageous to the back hand hitting method On the other hand, it has the disadvantage that it is difficult to handle short balls in the center of the body and in front of the net, and it is relatively weak on the forehand. In particular, when hitting in the forehand and backhand positions, there is a problem that the driving power is reduced because the table tennis ball does not have a sufficient spin.

In addition, since the table tennis racket according to the prior art has a structure in which the grip extends horizontally from the hitting portion, when hitting a table tennis ball with the grip held by the shake hand type grip, the wrist is broken downward. It is unnatural to stably adjust the hitting angle at the time of hitting a ball, and people who are used to table tennis to a certain extent also keep the hitting angle twisted and stable if they do not continue practicing. There was a problem that it was not possible to hit it.

In order to solve such a problem, according to the Republic of Korea Registered Utility Model No. 20-0428238 (registration date: September 29, 2006), the grip has a structure in which the grip is biased to one side of the racquet body and is oppositely inclined. Although a table tennis racquet is disclosed, the one described in Korean Utility Model Registration No. 20-0428238 has a structure in which the grip extends from the side of the racquet body instead of the center of the racquet body, so when holding the grip There is a problem that it is difficult to support the body stably and it is difficult to hit the ball accurately because it does not coincide with the center point of the racquet body, that is, the ball point (ball point).

In addition, a table tennis racquet is disclosed in the Korean Utility Model No. 20-2010-0005805 (released date: June 7, 2010), in which the grip is coupled so as to be inclined at a predetermined angle from the center of the racquet head. However, the Korean Utility Model No. 20-2010-0005805 still folds the wrist downward when hitting a table tennis ball by the grips being connected so as to be inclined at a uniform angle from the racquet head. In order to be forced to use, it is unnatural to stably adjust the hitting angle at the time of hitting a ball, and as a result, there is a problem that the hitting angle continues to twist and it is difficult to perform a stable hit.

Republic of Korea Registered Utility Model No. 20-0428238 (Registration date: September 29, 2006) Republic of Korea Public Utility Model No. 20-2010-0005805 (release date: June 7, 2010)

Therefore, the present invention is proposed to solve the problems of the prior art, and provides a more stable adhesion while providing a new grip which is completely different from the grip of the existing shake hand type. Its purpose is to provide a table tennis racket that can provide (clasping) and striking power.
