Description
Technical Field
The invention relates to a shape and a structure of a table tennis bat.
Background
The common table tennis bat is formed by gluing a bakelite bottom plate, a rubber and a sponge.
The performance of the base plate is related to the shape, structure and material of the base plate. Therefore, when purchasing the bottom plate, not only the appearance and the number of the film layers but also the wood grain arrangement structure need to be seen.
When the diameter of the particles of the rubber is large, the hitting feeling is hard, and when the diameter of the particles is small, the hitting feeling is soft; the glue reversing speed is high when the particle density is high, and the glue retaining ratio is low.
The main considerations for sponges are hardness and thickness. Generally, the harder and thicker the sponge is, the higher the elasticity is, and the hitting speed is high.
The concave cylindrical table tennis bat with the patent number of 2019112880753 applied by the applicant has a concave cylindrical surface, the hitting direction is changed greatly, but a straight bat and a cross bat are not distinguished, the grasping modes and angles of the bat are different, the using results are greatly different, and the playing result of a player playing with a wrong variety is not the same as that of a common bat.
Disclosure of Invention
The purpose of the invention is as follows:
the invention provides a table tennis bat with an arc surface and a rubber cover thereof, wherein the table tennis bat is accurate in ball receiving, changeable in ball returning direction and force, and suitable for being made into a straight bat or a horizontal bat respectively.
The technical scheme is as follows:
the cambered surface table tennis bat is formed by sequentially cementing a bottom plate, a sponge on one surface and a rubber on one surface, or sequentially cementing a rubber on one surface, a sponge on one surface, a bottom plate, a sponge on the other surface and a rubber on the other surface; the table tennis bat is a bat surface symmetrically arranged along the central longitudinal section.
Wherein, the bottom plate is composed of a plate surface or a racket handle.
One or two bat surfaces of the cambered surface table tennis bat are in the shape of a concave cylindrical surface, and the concave cylindrical surface is one of the following two structures:
(1) the thickness of each longitudinal section (the normal section from the top end of the racket handle to the lower end of the racket) parallel to the longitudinal section of the symmetry center is consistent, the thickness of the longitudinal section of the symmetry center is the thinnest, the thickness of the longitudinal sections towards the left side and the right side is gradually thickened, and the thickness of the longitudinal sections at the two sides is the thickest;
when a racket face is in a concave cylindrical shape, the side of each cross section (or called transverse section) which is perpendicular to the central longitudinal section and is positioned on the outer side of the rubber is a section of standard arc line section which is sunken inwards (the arc has the same arc radius), all the arc line sections have the same arc radius, and the sides of all the cross sections on the outer side of the bottom plate are straight line sections;
when the two racket surfaces are in a concave cylindrical surface shape, the edge of each cross section perpendicular to the central longitudinal section on the outer sides of the two rubber sheets is a section of standard arc line which is concave inwards, and all the arc line sections have the same arc radius.
(2) The thickness of each cross section perpendicular to the central longitudinal section is consistent, the thickness of the central cross section is the thinnest, the thickness of the cross sections at the upper end and the lower end is gradually thickened, and the thickness of the cross sections at the two ends is the thickest;
when one racket face is in a concave cylindrical surface shape, the edge of each longitudinal section parallel to the central longitudinal section on the outer side of the rubber is a section of standard arc line (the arc has the same arc radius), all the arc line sections have the same arc radius, and the edges of all the longitudinal sections on the outer side of the bottom plate are straight line sections;
when the two racket faces are in a concave cylindrical surface shape, the edges of each longitudinal section parallel to the central longitudinal section on the outer sides of the two rubber sheets are a section of standard arc line which is concave inwards, and all the arc line sections have the same arc radius.
The table tennis bat with the structure (1) is made into a concave cylindrical surface straight table tennis bat (a player holds the bat straight) with a shorter handle. When a user uses a straight bat to play a ball, the central axis (longitudinal section) of the straight bat grasped by the user is basically vertical (plumb) to a table tennis table board, the bat handle faces upwards, the bat surface is below, the radius of the circular arc is basically parallel to the table tennis table board, the circle center is in the direction of an opponent, and the two ends of the circular arc are on the left side and the right side (instead of the upper side and the lower side) of the circle center, so that the hit table tennis can easily fall on the table board of the opponent and can not easily fly out of the table, and the hit table tennis can not easily fall on the table board of the user through a net (when the two ends of the circular arc are above and below the circle center, the bad phenomenon is easily caused).
The table tennis bat with the structure (2) is made into a concave cylindrical surface transverse bat table tennis bat (a player transversely holds the bat) with a longer handle. When a user uses a transverse bat to play a ball, the central axis (longitudinal section) of the transverse bat grasped by the user is basically parallel to the table tennis table surface, the bat handle faces the body of the user, the bat surface faces outwards, the radius of the circular arc is basically parallel to the table tennis table surface, the circle center is in the direction of an opponent, and the two ends of the circular arc are also on the left side and the right side (instead of the upper side and the lower side) of the circle center, so that the hit table tennis can easily fall on the table surface of the opponent, is not easy to fly out of the table and is not easy to fall on the table surface of the user.
The cambered surface bat is convenient for stably receiving the table tennis, and the return table tennis can be controlled in a smaller area more easily under the condition that the direction of the return table tennis is changeable, so that the table tennis can be ensured to fall on the table tennis table surface opposite to the table tennis table surface.
By establishing a geometric model and calculating according to the size of a standard table and the conventional size of a racket, the radian of the concave cylindrical surface is preferably within a range of 2-10 degrees.
In the invention, the bottom plate is formed by bonding multiple layers of wood films or is integrally formed by plastic injection molding or is integrally compounded by composite materials, one surface or two surfaces of the bottom plate are provided with concave cylindrical surfaces, and the radian of the cylindrical surface of the racket surface is mainly determined by the bottom plate, so that the mechanical strength of the racket is higher.
The sponge or the single sponge is integrally made, one side surface of the sponge is in a concave cylindrical surface shape, and the other side surface of the sponge is a plane; the curvature of the racket surface is mainly determined by the sponge. The sponge is easy to manufacture by adopting the mould, and the manufacturing cost of the racket is lower.
The outer side surface of the rubber (composed of a rubber main body and particles connected to the rubber main body) with the particles is in a concave cylindrical surface shape, and the inner side surface of the rubber is a plane; the radian of the cylinder of the racket face is mainly determined by the rubber. Preferably, the cylinder radian of the rubber is mainly formed by different lengths of particles on the rubber, the particles at the central line are shortest, the particles at two ends of the arc are longest, the materials are the same, and the rubber can be molded at one time through a rubber molding machine and a specific mold. The longest and longer particles can be rubber columns with different diameters on the upper layer and the lower layer, the lower layer is thicker, and the upper layer is thinner (so that the longer particles are stable in shape and not prone to deflection, the bottom is harder, the upper end is softer, the hardness can be both considered, and the weight is lighter). The rubber has good appearance and three-dimensional effect; moreover, the length of the particles is different, the elasticity generated when the table tennis ball is hit by different parts is different, and the ball speed is also different. The cambered surface enables the direction of returning the ball to be variable, the speed to be variable due to the unequal length of the particles, the ball-returning device is difficult to adapt to a player at home at a stroke, and the ball winning probability of the player is greatly improved.
The second object of the invention is: providing the rubber sleeve of the cambered surface table tennis bat.
The second technical scheme is as follows: the other two layers of the cambered surface table tennis bat are glued together after the bottom plate is removed; one side surface of the sponge is in a concave cylindrical surface shape, and the other side surface is a plane; or the outer side surface of the rubber with the particles has a concave cylindrical surface shape, and the inner side surface is a plane shape.
The racket is used for being stuck on a straight racket bottom plate, and the thinnest part of the concave cylindrical surface which is sleeved with glue is stuck on a longitudinal section of a symmetrical center (the center line from a racket handle to the tail end); or the concave cylindrical surface is bonded on the horizontal central line (the longitudinal section perpendicular to the symmetrical center line of the horizontal beating bottom plate) of the horizontal beating bottom plate at the thinnest position of the concave cylindrical surface.
Has the beneficial effects that:
the racket of the invention has high ball receiving stability, and is easy to be used by a new hand; the direction of the returned ball is easy to control and fall on the table of the opponent. And even if the force of the player is the same, the player can hit the ball by adopting different parts, the speed of returning the ball can be changed more, and the player is inconvenient to receive the ball by the hands.
The invention also discloses a straight bat or a horizontal bat used by different players, which is characterized in that the straight bat or the horizontal bat is specially designed, the arrangement direction of the circular arc is completely different from the relative position of the longitudinal section of the bat, when in use, both ends of the arc line of the concave arc surface are arranged at the left side and the right side of the table, but not at the upper side and the lower side, and the stable and accurate effects of ball receiving and ball hitting obtained by the two types of bats are consistent and are obviously superior to the traditional straight bat and horizontal row.
In addition, the invention has the advantages of stable ball catching, changeable ball returning direction and force by adopting the cambered surface rubber. And the hit table tennis is not easy to fly out of the table of the opponent, and is not easy to drop nets or fly out of high balls to be vigorously taken by the opponent to lose the balls (the worse condition is easy to occur when the cover rubber of the invention is adhered to a transverse bat and a straight bat, and the ball control is even not as good as that of a common bat).
