Description

Table tennis bat

Technical Field

The utility model belongs to the sport equipment field, concretely relates to table tennis bat.

Background

At present, all the surfaces of table tennis bats are planes, and no matter professional athletes or ordinary table tennis amateurs are limited to be arranged on and under a bottom plate, glue and rubber to enhance the quick attack, rotation and ball receiving stability, for example, rubber such as reverse glue, positive glue, long glue (half-long glue), raw glue, arc-proof glue and the like are invented.

At present, the plane table tennis bat has some defects: 1. the structure of the racket is not uniform and can not be adjusted to the human condition. For example, some mass or semi-professional players prefer to spin on the arc, but have difficulty playing high quality games because the spin on the arc should be such that the force must be off center while the interaction time between the racquet and the ball is extended as much as possible. When the plane racket is used, the slope is controlled as well as possible, and the route of the racket is controlled well to play a better arc spin ball, so that the function of the racket is limited. 2. In the face of coming a ball, many people want to quickly attack the ball by increasing the hitting power, the best effect is that the returned table tennis ball is quickly rotated, and the use of a plane racket needs better skill to achieve the point. 3. When a plane racket is used, in some cases, in order to play a high-quality ball, the inclination between the racket and the horizontal plane is large, and the ball is easy to leak. For the general public, the planar racquets limit the enjoyment of the game, and for professional players, the technical improvement and tactical options can only be played around the planar racquets, so that the game has an improved 'ceiling'.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide a table tennis bat which can more easily realize the effect of hitting a rotary ball or quickly attacking or not eating a rotary ball.

The utility model adopts the technical proposal that: a table tennis bat comprises a handle and a bat plate, and is characterized in that the top edge and/or the bottom edge of the longitudinal section of the bat plate are/is arc lines.

Furthermore, the top edge and/or the bottom edge of the vertical section of the clapper is/are concave arc line.

Furthermore, the top edge and/or the bottom edge of the longitudinal section of the clapper is/are in a convex arc line.

The utility model discloses an actively the effect does: the utility model discloses a racket at least one side is concave surface or convex surface, can be the combination of the two, also can be the bat board both sides and be same shape, also can be the combination of above arbitrary shape and plane. When the racket is contacted with the incoming ball, compared with the traditional racket, the racket has larger deviation force to the center of the ball under the same inclination degree, and meanwhile, the interaction time of the racket surface and the ball is longer, so that a high-quality arc spinning ball is easier to play, and the ball is difficult to eat. Meanwhile, the effective hitting area of the racket is larger, and the ball leakage rate is lower.

Detailed Description

Example 1: as shown in the attached figures 1 and 2, the utility model comprises a handle and a bat panel, wherein the bat panel refers to a part of the bat for hitting table tennis balls, and has two structures: or comprises a bottom plate 1, a sponge, a rubber sheet 2 and the like; or only consists of the bottom plate 1, namely a single-wood racket. It will be appreciated by those skilled in the art that carbon layers and the like may also be included. In the present invention, the swatter surface refers to the surface of the swatter board.

The top edge and/or the bottom edge of the longitudinal section of the clapper is arc-shaped. As shown in FIG. 2, the paddle has a longitudinal cross-section abcd, with the top side being edge da and the bottom side being edge bc.

In the embodiment, the side da is a concave arc line, and this case can be divided into two structures, one is that the bat surface is in the form of an arc as shown in fig. 2, which is the embodiment. Still another structure is the structure of embodiment 3 shown in fig. 4 and 5, that is, the whole bat surface is concave to form a shape similar to a "pan".

The embodiment has three realization forms, one is that the surface of the bottom plate 1 is a plane, and the outer surface of the rubber sheet 2 is designed into an arc line; the other is that the surface of the bottom plate 1 is designed into an arc line form, and the surface of the rubber sheet 2 is a plane; in another embodiment, the surface of the base plate 1 is designed in the form of an arc, and the outer surface of the rubber sheet 2 is also designed in the form of an arc. The utility model discloses what consider is the face of clapping form of end product, and the clapper that adopts these three kinds of forms to finally produce all can realize the structure of the face indent, and the limit da of its longitudinal section is the pitch arc of indent promptly, when the clapper contains other structures, still can not influence the protection scope of this patent. The embodiments mentioned below can also be used in these three different ways to achieve a corresponding shaping of the surface of the resulting racket board.

The plane of the racket body mentioned in the patent refers to the horizontal center plane of the racket plate when the racket is horizontally placed.

Any point of the racket surface (including the racket plate edge) is selected as a concave point and is taken as the lowest point on the racket surface, the vertical straight line distance of the concave point lower than the racket edge (if the concave point is at the racket edge, the concave point is lower than the edge opposite to the racket) is defined as the concavity, the measurement unit of the concavity can be set as the currently used length unit of millimeter, centimeter, decimeter, meter and the like, and the concave point gradually rises to the racket edge by an arc line. In one extreme, the concavity is zero millimeters, i.e., the table tennis bat is flat, and in the other extreme, infinite. The concavity increases slowly from zero, and is always one concavity, which is suitable for the common people or professional athletes. For example, the concave point is at the center of the racket, the concave point gradually rises to the edge of the racket, the concavity is 0.01 mm (the difference between the concave point and the racket is difficult to distinguish by naked eyes) to 1 cm, and the interval is a good interval for the concave table tennis racket to play. The concavity is more than 1 cm, and the complete control can be realized by extremely high skill.

When the player and the common people use the plane racket, the racket and the horizontal plane present a certain inclination. For example, a flat racquet paddle at 50 degrees to the horizontal (130 degrees to the horizontal on the other side of the racquet) can produce a relatively spiral ball. The table tennis bat is used for batting at the same angle and the same strength, and the concave bat has a certain radian, so that when the table tennis bat is used for batting, the deviation force to the center of the ball is larger on one hand, and the interaction time between the arc bat surface and the ball is longer than that of a plane bat on the other hand, therefore, the high-quality arc rotary ball is easier to play, and the rotary ball is less easy to eat. If one wants to achieve the same quality and effect as when hitting a flat racket, the concave racket can hit a table tennis ball with an angle larger than that of the flat racket. Here, a concept of "effective striking area" is also introduced: the racket and the horizontal plane form a zero-degree included angle, namely, the racket is used for hitting the ball at the edge, the effective hitting area is '1', the ball leakage rate is very high, the angle formed by the racket and the horizontal plane is gradually increased, the effective hitting area is also gradually increased until the included angle of 90 degrees is formed, the effective hitting area is the area of the whole table tennis racket, and the ball leakage rate is minimum. Thus, between 0 and 90 degrees, the greater the angle the racquet makes with the horizontal, the greater the effective hitting area. The concave racket can play the same effect by using an angle larger than that of a plane racket to hit a table tennis ball, but the effective hitting area is increased, the ball leakage rate is correspondingly reduced, and the skill requirement on athletes and common people is lower. For the common masses, the difficulty of skill use is reduced, and the interest of playing the ball is increased. Professional athletes can adjust the technical and tactics and play games with better quality.

Example 2: as shown in fig. 3, only the outer side of the longitudinal section abcd is shaped such that side da is convexly curved.

This case can be divided into two structures, one is in the form of convex arc shape as shown in fig. 3, that is, the structure of this embodiment. Still another structure is the structure of embodiment 4 shown in fig. 6 and 7, namely, the whole racket face is integrally protruded outwards to form a shape similar to an inverted 'pot'.

Any point of the racket surface (including the racket edge) is selected as a convex point and is taken as the highest point on the racket surface, the vertical straight line distance of the convex point higher than the racket edge (if the convex point is at the racket edge, the convex point is higher than the edge opposite to the racket) is defined as the convexity, the measurement unit of the convexity can be set as the length unit of millimeter, centimeter, decimeter, meter and the like which is currently used as the measurement unit, and the convex point slowly descends to the racket edge by an arc line. In one extreme, the convexity is zero millimeters, i.e., the table tennis bat is flat, and in the other extreme, it is infinite. The convexity is gradually increased from zero, and the convexity always has one convexity, so that the method is suitable for common people or professional athletes. For example, the convex point is at the center of the racket, the convex point gradually descends to the edge of the racket, the convexity is 0.01 mm to 1 cm (the difference between the convex point and the plane racket is difficult to distinguish by naked eyes), and the convexity is a good range for the convex table tennis racket to play. The convexity is more than 1 cm, and the complete control can be realized only by extremely high skill.

Generally speaking, when a player and the common masses use a plane racket, the player and the common masses need to press the racket (press the racket) as much as possible, namely, when playing the ball, the racket and the horizontal plane present a certain inclination, if the racket is convex, a proper convexity is selected, and the effect obtained by pressing the racket can be realized without specially pressing the racket during playing the ball, and even the effect is better. The reason is that when the table tennis bat is held by the right hand, if the bat is a bat with small convexity, when the bat touches the table tennis ball, with the same strength and the same striking, three differences can be generated with the plane bat: firstly, when the racket and the ball act, the racket surface is convex, so that the deviating force between the racket surface and the ball center is larger, and the rotating speed is higher; secondly, the acting force is larger because the racket face is convex. Even if the convexity is not high (for example, 0.1 mm, the difference between the table tennis bat and a plane bat can be slightly perceived when the table tennis bat is touched by fingers, and the table tennis bat is difficult to distinguish by naked eyes), because the table tennis ball is light, the effect of weighting rotation during hitting the table tennis ball is very obvious, and the table tennis ball can be hit out and hit back at a higher speed and a higher rotating speed; thirdly, the racket surface is arc-shaped, so that the racket is not easy to eat and rotate. With a convex table tennis bat, it is easier for the general public to practice to play a fast and relatively rotating ball than a flat bat, and professional athletes can choose more technical and tactical skills to play a better quality game.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present invention.
