Description

Table tennis rackets {TABLE TENNIS RACKET}

More particularly, the present invention relates to a table tennis racket, and more particularly, to a table tennis racket in which a thumb supports the outer side connected to the racket head while gripping the racket and supports the back of the racket head, A grip which is extended from the racket head so as to surround the finger and the little finger and is inclined in one direction from the center axis of the racket head so that the index finger is aligned with the center axis of the racket head, The present invention relates to a table tennis racket that provides a stable hit.

Generally, a table tennis racket includes a racket head having a rubber attached to one side or both sides thereof, and a handle extending from the racket head. These table tennis racquets can be divided into pen-holders (with rubber on one side of the racket head) or shake hand type (with rubber on both sides of the racket head) depending on the way they grip.

The pen holder type grip method is a method of pressing the front face of the racquet with the thumb and index finger, holding the back of the racquet with the stop and the finger, and catching the grip of the racquet like holding the pen. While it is advantageous for forehand attack, it has the problem that it is relatively uncomfortable because the backhand range is narrow because it uses only one side, and the relative range of the left and right defense is narrow.

The shake hand type grip method is a method of grasping the hand grip of the racket like a handshake. It is advantageous in the method of the table tennis ball curd, and the use of both sides of the racket reduces the physical power consumption and advantageous for the backhand method. On the other hand, And it is relatively weak for the forehand. Especially, there is a problem that the driving force is decreased because the spin is not sufficiently applied to the ping pong ball when hitting with a forehand and a backhand posture.

In addition, since the table tennis racket according to the related art has a structure in which the handle is horizontally extended from the hitting part, it is necessary to use the shake hand type grip method in which the grip is gripped and the wrist is bent downward when hitting the table tennis ball. It is unnatural to adjust the angle of the ball stably, and there is a problem that the person who is somewhat familiar with the table tennis does not continue practicing, and the angle of the batting continues to be changed so that the player can not stably hit.

In order to solve such a problem, a ping-pong racket having a structure in which the handle is biased to one side of the racket body and tilted in the opposite direction has been proposed in Utility Model No. 20-0428238 (Registered on Sep. 29, 2006) No. 20-0428238, it is difficult to stably support the racquet body when the grip is gripped, because the handle is formed by a structure in which the handle is extended from the side rotor rather than the center of the racquet body, and the center point of the racquet body, There was a problem that the correct ball was difficult to match.

In addition, in the Korean Utility Model Utility 20-2010-0005805 (published on June, 2010), a table tennis racket in which the handle is inclined at an angle from the center of the racket head has been proposed, -0005805, since the knob is inclined at a uniform angle from the racket head, it is necessary to use the wrist to be bent downward when hitting the table tennis ball. Therefore, it is unnatural to stably adjust the angle of the ball when the ball is hit, There was a difficult problem that was stable and stable.

KR 20-20-0428238 Y1, Sep. 29, 2006. KR 20-2010-0005805 U, 2010. 06. 07.

Preferably, the handle comprises a connecting portion extending from the racket head, the connecting portion being inclined at a first angle about the racket head; And a grip portion extending from the connection portion and inclined at a second angle larger than the first angle about the racket head.

Preferably, the contact portion protruding in a direction opposite to the tilting direction of the connection portion is formed on the outer side of the connection portion where the parent region of the palm is closely contacted during the grip.

Preferably, at the time of gripping, the stopper, the finger grip and the gripping portion to which the little finger is brought into close contact are protruded in a direction in which the grip portion tilts, and are inserted between the stop and the finger grip, May be formed.

Preferably, the grip portion is formed with a fitting groove extending inwardly from the end portion, and further includes an extension portion inserted in the fitting groove to extend the length of the grip.
