WO1999015244A1 - New style table tennis bat - Google Patents

Abstract

A new style table tennis bat has several concave portions for receiving the fingers of a player and an assistant handle. The invention changes the conventional types of hand grip, assists and compensates for body's joint activity so as to make it easy to control the blade and improve the quality of striking and serving.

Description

 The present invention relates to a table tennis racket, and in particular to a table tennis racket that assists and / or compensates human joint activities and can swing freely.

 Traditional table tennis rackets are horizontal-grip rackets, commonly known as broad-blade rackets, and vertical-grip pen-holders developed on the basis of broad-blade rackets. People have been using this racket for table tennis for many years. However, in the above two table tennis rackets, especially the vertical and vertical grip, the wrist joint cannot move completely freely. When the backhand is used, it is much more difficult to hit the ball than the forehand. This is caused by the backhand use of the racket. A series of opposite joint movements is limited by the inability of human joints to move backwards, so backhanding is a major obstacle to table tennis. This weakness is entirely due to the unreasonable structure and holding posture of the ping-pong racket.

 When using a traditional table tennis racket, the attitude of the racket is mainly determined by the following joint movements: the hemisphere joint of the large shoulder moves in the hemisphere orientation; the elbow joint, except for its vertical axis, is less than 180. In addition to the rotation, it can also twist in a certain direction about the axis of the arm itself; the wrist joint is basically made less than 180 about its vertical axis. Of rotation. The hemispherical rotation of the large shoulder and the elbow joint around its vertical axis are less than 180. The rotation of the camera cannot be fully utilized when shooting with the backhand.

 The object of the present invention is to provide an ergonomic table tennis racket with a new structure. It not only gives full play to the functions of the joints of the fingers, but also the function of the universal ball joint formed between the finger sockets of the fingers and the racket, to assist and / or compensate the movement functions of the joints of the human hand and shoulder arm.

 The above object of the present invention is achieved by the following structure.

At the appropriate position on the upper part of the table tennis racket, dig several finger sockets from the back of the ball board. It is more appropriate to dig four finger sockets. The index finger, middle finger, ring finger and little finger are used to hold the ball board together, so that between the fingers and the socket Form ball joints respectively. The thumb passes over the shoulder of the board and holds the board from the front of the board. The handle of the traditional racket is no longer a hand-held handle, but forms an auxiliary support rudder for holding the new racket and / or cooperates with the finger socket to form a pair of force couples It is also possible to form a generally horizontal semi-cylindrical boss at an appropriate position on the front upper part of the ball board, and dig the above four finger sockets from the back of the ball board inward and upward to the semi-cylindrical cone. Inside the boss, a thumb recess is dug out on the semi-cylindrical boss on the right shoulder of the front, for holding the racket when the ball is struck by the front and back. The racket of this structure completely changes the grip of the table tennis racket. Replacement page (Part ¹ of Article 26) It has the following significant advantages:

 1 Because the joints of the fingers and the universal ball joints between the finger and the socket are fully utilized, and the wrist is completely free to move, it not only compensates the movement function of the backhand pat, but also assists the forehand pat. In addition, the movement of the small joints is much quicker than that of the elbow and shoulder joints, which greatly improves the speed of changing the attitude of the racket in response to the impact, and makes the impact speed, straight line and rotary impact strength, attack and defense angle The azimuth and range as well as the maneuverability have been greatly improved, allowing for free swing and greatly improving the quality of the hit.

 2 Eliminate the dead angle, you can attack and defend in all directions. You can use the forehand or the backhand to hit the ball, or you can use the backhand or the backhand to make the backhand and the middle have the same offensive and defensive capabilities.

 3 Greatly reduce the fatigue of the athlete's hands and shoulders, so that the athlete's hands, arms, shoulders and all joints are always in a very relaxed state.

 The racket of the present invention will now be described in detail through preferred embodiments with reference to the accompanying drawings.

 FIG. 1 is a schematic front view of an embodiment of a novel table tennis racket of the present invention;

 FIG. 2 is a rear view of FIG. 1;

 FIG. 3 is a partial side sectional view of FIG. 1;

 4 is a schematic front view of another embodiment of the novel table tennis racket of the present invention;

 Figure 5 is a rear view of Figure 4;

 Figure 6 is a partial side sectional view of Figure 4.

 among them:

 ① is the ball board;

 ② It is the auxiliary support rudder and / or hitting point for the racket;

 ③ is the index finger socket;

 ④ is the middle finger nest;

 ⑤ is ring finger nest;

 ⑥ is the small thumb socket;

 ⑦ is a generally horizontal semi-cylindrical boss;

 ® is a pit for the thumb.

In one embodiment (Figs. 1-3), at least one hole is dug out from an appropriate position on the upper surface of the back surface of the ball plate 1, preferably four holes. The thickness and size are different, and the position can also be staggered naturally according to the natural curve of the fingers. It is better to hold the hands together. The finger sockets can be sloping from the back of the ball to the inside and upward. Dig to a certain depth to form ball sockets that fit with each finger. Auxiliary support for rackets The rudder 2 does not have to be as long as the handle of a traditional racket.

 In another embodiment (Figs. 4-6), a substantially horizontal semi-cylindrical boss 7 is provided on the upper part of the front surface of the ball plate 1, and four cone-shaped finger sockets 3 are dug out inward and upward on the back of the ball plate. , 4, 5, 6, and a thumb pit is dug on the semi-cylindrical boss 3 on the right shoulder of the front of the ball 8. The auxiliary support rudder 2 of the racket can be made into an egg shape.

 The racket can be oval, rectangular, trapezoidal, inverted trapezoidal or round.

 Practice has proved that after using the racket of the present invention, after a short period of adaptive training, it can swing freely. Its batting, serving strength, rotation speed, alertness, and full range of motion are far beyond those of a passing racket. This is because this racket structure and the corresponding grip position are the most scientific. It raises the traditional racket structure and its holding method to a new height, and gives full play to the table tennis player's function. Therefore, it The emergence of the game will undoubtedly cause a revolutionary change in the field of table tennis.

 Although the present invention has been specifically illustrated and described through the above embodiments, it does not exclude that various modifications and changes are made to the present invention in accordance with the concept and principle of the present invention.
