  The present invention relates to an improvement of a table tennis racket.

  Today, table tennis has been developed as a sport that can be enjoyed regardless of age or gender, due to the hosting and broadcasting of the Summer Olympics and the World Table Tennis Championships.

As table tennis develops as a sport, the number of people who want to improve their technical capabilities is increasing, and one of the improvements in technical capabilities is that the usage of the racket is greatly influenced by the difference in how the racket is gripped. There are two main types: shake hand type and pen holder type.
The former is said to be the mainstream method of gripping because it is easy to switch between forehand and backhand and is particularly suitable for backhand attacks.

The latter has excellent operability with a snapped wrist and is easy to fine-tune the racket angle etc., but basically the forehand and backhand are hit only on the surface of the racket, so the racket head when gripping the racket There are cases where the attacking power is lacking, for example, the portion is lowered and the ball that has come to the Fomidle cannot be hit back effectively.
Furthermore, the grip portion is formed in an elongated rod-like body, and the grip portion can be easily gripped with the thumb and index finger, while the contact area between the thumb and index finger and the grip portion is small, so that the racket can be gripped stably. It is considered difficult.

From this point of view, the following conventional techniques exist as table tennis rackets capable of effectively hitting the forehand, backhand and middle balls regardless of the shake hand type or pen holder type.
For example, in Patent Document 1, a gripping part protrudes from a racket body and is fixed in an oblique shape, and a finger hook notch is provided on the racket body on the side of the gripping part, and a finger contact protrusion is provided on the back surface of the racket body. Thus, there is disclosed a table tennis racket that can firmly hold the racket body in a stable state and can be used at a desired inclination and rotation angle.

  In Patent Document 2, two grips are provided on one hypotenuse of the gripping part, and a block-like pad having a curved surface is disposed between the recesses, thereby accurately holding the gripping part. There has been disclosed a table tennis racket that can be changed freely by changing the way in which the finger holding the racket is placed.

In Patent Document 3, by providing a cylindrical finger-hanging portion that protrudes from the surface of the hitting ball portion and protrudes from both side surfaces of the holding ball portion at the continuous portion of the hitting ball portion and the holding portion, the shake hand type can swing at high speed. Even in this case, the force applied to the ball striking surface is stable, and in the case of the pen holder type, the contact area between the finger hook portion and the finger is increased, and a table tennis racket that can stably hold the racket is disclosed. Yes.
