Description

Table tennis racket

The present invention relates to a table tennis racket, and in detail, the thumb supports the outer portion connected to the racket head in the gripped state, the index finger is extended in the racket head direction to support the back of the racket head, stop, It extends from the racket head to surround the ring finger and the little finger, and provides a sense of stability when grip by providing a handle inclined in one direction from the center axis of the racket head so that the index finger coincides with the center axis of the racket head. It relates to a table tennis racket that provides a stable hit.

In general, a ping pong racket includes a racket head on which rubber is attached to one or both sides of the ball and a handle extending from the racket head. Such a table tennis racket may be divided into a pen-holder (rubber attached to one side of the racket head) or a shake hand type (rubber attached to both sides of the racket head) according to the grip method.

Pen holder-type grip system uses the thumb and index finger to press the front of the racket and supports the back of the racket with the middle finger and the ring finger to hold the handle of the racket as if grabbing a pen. It can control and exert delicate technology, and has a favorable advantage in the forehand attack, while using only one side, the backhand range is narrow and uncomfortable.

Shake hand grip is a method of holding the handle of a racket as if shaking hands. It is advantageous to the curd stroke of table tennis balls, the physical strength is consumed by the use of both sides of the racket, and it is advantageous to the backhand method. Difficulties dealing with short balls and relatively weak forehands. In particular, there was a problem that the power of the drive was reduced because the spin of the ping pong ball was not sufficiently caught in the forehand and backhand posture.

Furthermore, since the table tennis racket according to the prior art has a structure in which the handle extends horizontally from the batting part, the user must bend the wrist downwards when using the shake hand type grip method when batting a table tennis ball while the handle is gripped. It is unnatural to hit the ball angle stably, and even if some people are familiar with table tennis, the angle of the ball keeps turning if it is not practiced.

In order to solve this problem, the Republic of Korea Utility Model No. 20-0428238 (Registration date: September 29, 2006) proposed a table tennis racket with a handle inclined to the opposite side of the racket body, but the Republic of Korea Utility Model In the case of No. 20-0428238, the handle is made of a structure extending from the side rotor rather than the center of the racket body, so that it is difficult to stably support the racket body when the handle is gripped, and the center point of the racket body, that is, the ball point and the horizontal line There was a problem that the exact hits were difficult to match.

In addition, the Korean Utility Model Model No. 20-2010-0005805 (published: 2010.06.07.) Proposed a table tennis racket in which the handle is inclined at an angle from the center of the racket head, but the Korean Utility Model Model 20-2010 -0005805 is unnatural in hitting the batting angle stably when hitting the ball as the handle is inclined at an even angle from the racquet head, so it must still be used to bend the wrist downwards. There was a problem with a difficult batting stable.

Accordingly, the present invention has been proposed to solve the problems of the prior art, while providing a new grip method that is completely different from the existing shake hand-type grip method, while providing a more stable adhesion (grip force) and a hitting table tennis racket The purpose is to provide.
