Description

Penholder grip

One, technical field

The utility model relates to a kind of table tennis bat.

Two, background technology

Table tennis bat has Chinese pen-hold grip, the square pen-hold grip of Japan and Korea S, shake-hands grip and other New racket etc.The existing penholder grip of China is made up of striking plate and handle, handle is by with base plate all-in-one-piece handle be pasted onto respectively on handle, the handle bar of lower surface is formed, its cross section ovalize, the nose thickness of handle is less than the tail end thickness of handle, on, lower handle strip is the same and opposed bottom central plane symmetrical, playing ball with the racket of this kind of moulding to make the clever feature of the Chinese people of industry and intelligence be given full play to when playing table tennis and show, the bead epoch of diameter 38mm are adopted at table tennis, in international tournament, also brilliant military success was really had by the play of this racket backhand block with forehand, now still exist in a large number in the market, and widely used by paddler and fan.After 1 day October in 2000, the large ball of diameter 39.50-40.50mm used instead by table tennis, on July 1st, 2014 rises, table tennis diameter again on be transferred to 40.00-40.60mm, material changes new plastics into by original celluloid, by bead to large ball, the diameter of table tennis adds about 5.3%, volume adds about 18%, and the quality of table tennis becomes 2.7g from 2.5g, adds 8%; The formula of the rotary inertia of the spherical shell of uniform quality distribution is (2/3) mR ²so table tennis adds more than 20% by the rotary inertia after bead changes large ball, even if the large ball that we get only need maintain speed and the rotation of the bead got, also need to provide more translational kinetic energy and rotational kinetic energy to table tennis, that is will do more merit to table tennis in impact.Because the increase of rotational inertia of table tennis ball is more, the rotation of manufacture and change ball becomes more difficult.After using large ball instead, on the one hand that the speed of table tennis when selling is large like that when not easily reaching bead, simultaneously also because suffered air drag increases when table tennis aloft flies, velocity of shuttle flight has slowed down, so the rhythm of playing ball is slack-off, this tackles ball to us and leaves the more time, can Grounding more fully.Above-mentioned situation shows, the probability of playing table tennis by score of playing some prank or other diminishes, directly hold push and block technology if be very important in the bead epoch and have its reasonable and apodictic words, and it should coordinate just effectively with other technology is ingenious in the large ball epoch, only can not consider push and block now and not focus on disappearing and draw other technology that waits of beating, more can not push and block as the unique technical of directly holding or whole technology, this primary level just directly held, on the other hand, pen-hold grip abandons push and block completely, no matter be attempt from other play with former pen-hold grip, or other design of new racket moulding is all the performance lacking Materialist Dialectics method, also successful all not in practice, the key issue of directly holding improvement how reasonably to accept or reject, the large ball epoch play ball needs large gimmick, score must have more strong means.Reaction speed (reaction time) when people play ball has the limit, the performance that will have in play, gains the initiative, and makes the ball got more excellent, objectively needing can be in time with racket square stance, face is controlled in adjustment well scientifically and rationally, and can fully effectively have an effect, and the placement got just can be made more accurate, sell faster, ball speed is larger, rotates stronger, changes more.Table tennis is changed into the large ball of diameter 40mm by international table tennis organization decided by the bead of diameter 38mm, add the sight of ping-pong contest, also be the needs of table tennis development to a certain extent, but also there is foreign country to suppress the suspicion of China, because the strength of Chinese table-tennis motion is too strong, bead changes large ball and existing pen-hold grip backhand difficulty is attacked, forehand room is large, treatment face is little, poor stability, the native defects such as ability at a stalemate is weak become more outstanding, table tennis is as the national ball game of China, in several necessarily even 100,000,000 crowds played table tennis, not within minority with pen-hold grip person, play also differs from one another, colourful, but it is really little directly not hold person in present high-caliber paddler, the result that this inherent shortcoming performance to sportsman's potential that can't but be existing pen-hold grip restricts to some extent, the large ball epoch of table tennis, need directly to possess renewal, rationally more scientific, the play of more advanced practicality, time the improvement of pen-hold grip and upgrading have been arrived instant.Japan, the square pen-hold grip of Korea S, relative moulding when holding bat between hand and bat is fixed, though froehand-backhand attacking driving is convenient to have an effect, look after face large, hand-type of holding bat is relatively fixing, the adjustment underaction of face, the ball of diverse location, different performance is tackled in inconvenience in time scientifically and rationally.Numerous bat of table tennis of the patent No. comprising my invention in recent years occurred to be ZL99204508.8 and the patent No. be ZL200420014133.6, that football fans have the one of common recognition to react to original pen-hold grip existing problems, also be the actively useful exploration that never faced by Tongfang, racket carries out, though differ from one another, but understanding and design also there is various deficiency, satisfactory not enough, user is few, also little on market.Westerner has dinner with knife and fork, and play table tennis with shake-hands grip, horizontal froehand-backhand of holding can better be had an effect, and looks after face large, and middle far from the table ability at a stalemate is strong, but froehand-backhand position exchanges batting switches face and need the time, more weak in the platform of Road.Asians eats with chopsticks, to play table tennis multiplex pen-hold grip, directly holding is the reflection of the eastern civilization in table tennis, the Chinese nation is the nationality of be good at thinking and study, Chinese civilization be can and be good at using for reference and absorb the civilization of other all outstanding civilized achievements, since bead is conducive to horizontal holding after changing large ball and is unfavorable for directly holding, we to original pen-hold grip to carry out objective science practical analyze, take the viewpoint that namely dialectical negative is sublated, retain its rational factor, eliminate its disadvantageous obstacle, and consciously learn and draw horizontally the advantage of other racket such as to hold and avoid its weakness, the moulding of Improvement and perfection pen-hold grip, effectively could promote the function of pen-hold grip, strengthen pen-hold grip in vitality under the new situation, and create ping-pong again and hold the new splendidness of play, to carry forward my the eastern civilization.

Three, summary of the invention

The purpose of this utility model directly holds faced new challenge after being to use according to table tennis the large baton round that diameter is 40+mm instead, by to existing improvement of directly holding bat handle and the moulding of throat position, being in one's hands claps hands on shape is done delicate adjustment, to overcome the shortcoming of original pen-hold grip and to develop its advantage, a kind of new penholder grip is provided, hold smoothly comfortable, stable flexibly, both be convenient to adjust face in time when playing ball put in place, also be convenient to scientific and reasonable, fully effectively have an effect, in treatment bench, middle is enough flexible, straight-holding and horizontal-beating applicability is strong, treatment face is large, steadily and surely at a stalemate, react faster, play ball more accurate, more ruthless, more turn, change more, attack and defense ability is stronger, to take part in the match more excellent good-looking penholder grip.The object of this racket invention is also to clap hands by being in one's hands in shape and play and reflects mutually with mutual of other racket such as shake-hands grip, is directly held under the new situation to the warfighting capabilities of other racket to improve.Because mainly Chinese use Chinese style pen-hold grip, this penholder grip is also in order to Chinese table-tennis team team member can obtain better achievement with this racket in international tournament.In a word, the invention of this bat of table tennis is to serve football fan better, revitalizes and directly holds, do credit to one's country, build dream China.Asymmetric due to the upper and lower handle bar of this bat handle, so should not the use of falling face.

The utility model penholder grip, forms by striking plate with the handle that striking plate is connected as a single entity.Striking plate is oval substantially, has the pointed throat of obvious peach between striking plate and handle, and the leading section of namely takeing on supreme handle bar by the bat of striking plate narrows from the width gradually, and the throat part shape shape as pointed in peach that striking plate is connected with handle turns around and is connected with branch.Handle bonds upper and lower handle bar respectively by the wooden base plate extension of striking plate point two sides and forms.Upper handle bar is shorter than lower handle bar, the part relative with lower handle bar front end thick, and upper handle bar is just in time empty, upper handle bar postmedian is thicker, thinning gradually from middle part to front end, shape as splitter, front end can only close to but throat inside can not be stretched into, handle bar rear end is wider, narrow gradually forward, upper handle bar both sides are symmetrical relative to axis, thicker along axis, both sides are thinning gradually, and surface is smooth arc-shaped surface.Lower handle bar is longer than upper handle bar, and front end puts in throat inside, and it is thin that lower handle bar entirety comparatively goes up handle bar, middle part is the thinnest, and the sponge that interior thickness and base plate lower surface are pasted is suitable with rubber gross thickness, and front end is slightly thicker than middle part, about 20 °, front end face inclination angle, rear end is slightly thicker again than front end, and lower handle bar both sides are also symmetrical relative to axis, thicker along handle bar axis, both sides are thinning gradually, handle bar rear end is the widest, and middle part is the narrowest, and surface is smooth arc-shaped surface.Because handle upper and lower handle strip is not identical, upper and lower handle bar is asymmetric to base plate.

The utility model penholder grip, lower handle bar front end is slightly thick and stretch into throat position compared with middle part, ensure that striking plate face and the intensity be connected between handle, unlikelyly ruptures, simultaneously its restriction hand of holding bat can not stretch in striking plate face, too much in order to avoid the flexibility that overslaugh is held bat.Thinner and suitable with rubber gross thickness with the sponge of lower face in the middle part of lower handle bar, when holding bat, tiger's jaw is at this position, when can ensure to hold bat, middle finger and face coincide very well, capable of expansion and contraction, also reduce the angle that forefinger and middle finger when holding bat refer to that root one saves between (connecting palm one to save) simultaneously, improve the whole comfort level holding bat, and it is thinner in the middle part of the sponge of lower face and rubber gross thickness and lower handle bar, when holding bat, forefinger and middle finger refer to that the angle of root between saving is less, the feel of attacking when disappearing lifting the ball is also better, so the lower face sponge of pasting and the thickness of rubber and lower handle bar interior thickness all thinner better, certainly, lower face is non-sticking subsides sponge and rubber also, just so can not play ball with directly holding the anti-technology of beating.Upper handle bar comparatively descends handle bar short, upper handle bar front end and throat surface area refer to and forefinger activity space for mother, ensure that the free degree movable between racket and hand, which also eliminates former pen-hold grip and adjust obstacle not in place at froehand-backhand diverse location different batsmanship square stance face.If the handle bar that the lower handle bar of this racket and the patent No. of my invention are the penholder grip of ZL200420014133.6 has the words of certain similitude, previous section makes it to shorten that this racket by the front end mute of common pen-hold grip handle bar, and surface is the curved surface of intermediate projections, and it is very crucial with the moulding of the combination of the lower handle bar of this racket, this makes whole hand of holding bat moderately recess striking plate face portion, eliminate the obstacle that handle bar front end is rotated face, hold this and pat the sense that ball just has backward the sea and sky are boundless, the potential of pen-hold grip is just released.Due to the preceding feature of handle and the moulding of the pointed throat of peach between striking surface and handle, when directly holding this racket, the third finger both can lean against near middle finger and assist to control face after striking plate, also naturally can lean against and clap near shoulder and throat on limit, even be exposed to control face by the finger of the third finger, this is not only easier adjusts to the right place face, also more can fully effectively have an effect, when needing, nameless also can the tangential motion of boosting base plate, this penholder grip is anti-is referred to as new straight hold.The science adjustment of this pen-hold grip throat position and handle moulding causes directly shaking hands the delicate change of shape, is to play ball the basic guarantee that quality is improved and improves with this pen-hold grip.Handle upper and lower handle bar surface is all smooth curved surface, ensures that racket and the relative moulding of holding bat between hand can consecutive variations, is convenient to as required, tackles the ball of diverse location different performance rightly.Lower handle bar rear end and upper handle bar postmedian thicker, ensure that enough stability of holding bat.Racket and new moulded of handle, ensure that new racket directly holds good hand touch of playing ball, shot unfolds smoothness.

The utility model penholder grip, due to the flexibility of face regulation and control, in process Road, platform, bead is enough good.Play ball with this racket, due to being identical of middle finger and face, the direction of having an effect of hand is directly consistent to the direction of ball actual force with bat, thus improve the accuracy that batting arrives impact point, this is actually to eliminate often exists an angle with play ball have an effect direction and the face of hand of traditional pen-hold grip to the force direction of ball, say it is systematic error from the angle of experiment, this is not only an Advanced Idea in design, thousands of times true perception under battle conditions especially.Owing to naturally holding bat state striking plate and arm on the same line, be convenient to make full use of " whipping effect " and fully have an effect, the speed getting ball can be improved.The third finger can swing in the acceleration tangentially of boosting face, can increase the rotation of ball.A finger and middle finger can be only had to stretch into the racket back side because this directly holds racket, the third finger leans against very naturally claps point with on throat limit, this and horizontally hold the hand shape of holding bat forefinger finger being stretched into face and have similarity, when human body and hand deformationization little, face just can be adjusted to the right place by the minor motion of finger easily, no matter be translation or rotation, the less movement of finger all can drive face to have comparatively big-movement to ball, thus promote the quality disappearing and beat and the batsmanship such as to draw, and hold bat smoothly, swing the bat and unfold, so froehand-backhand position and middle far from the table with horizontal hold equally good, treatment face is large, attacking and defending ability at a stalemate is all very strong.Certainly, hold the same with horizontal, when serving a ball with this racket, each finger all can go deep into deeply holding racket in striking surface, and has an effect with different hand shapes of holding bat, and is convenient to the ball sending different performance.Due to the multiplex same striking surface batting in froehand-backhand position, without the need to changing face, so the reaction of froehand-backhand position conversion batting is held soon than horizontal.Because the moulding of this racket makes the angle of straight-holding and horizontal-beating become reasonable and adjustable, thus expand the scope of application of straight-holding and horizontal-beating.Play ball in process, also be because finger of holding bat stretches into face not bery deeply, backhand ball tow sides batted and changes easily nature, if the sponge of both sides face is different with rubber, the ball performance hit is also different, exchanges suddenly the difficulty that use can strengthen opponent's reply.

The utility model penholder grip, its design is based on the correct understanding to the Laws of Mechanics of playing table tennis.Face to the elastic force direction of ball perpendicular to face, and the direction of frictional force is along face, clap direction that ball is made a concerted effort and face normal direction has an angle, different rubber is different from table tennis coefficient of friction, so resultant direction is different from the angle direction of face, because stiction is variable between zero and maximum static friction force, so, namely same rubber is used to play ball, angle between resultant direction and face normal can be variable between zero and a certain maximum angular, exceeding this maximum angular is must occur eating ball phenomenon, namely ball is not walked along direction of swinging the bat, this angle is critical angle, this critical angle is determined by the coefficient of friction of rubber, I records in experiment, new anti-glue rubber and the confficient of static friction of table tennis are between 2.0 to 2.5, its critical angle is between 63 to 68 degree, namely between resultant direction and face the most I of angle to 27 to 22 degree, be commonly called as wiping ball very thin, the design of Here it is this racket will make to hold bat the reason that feel reaches best from different perspectives, the positive glue rubber had and the confficient of static friction of table tennis are between 0.1 to 0.2, its critical angle is between 5 to 10 degree, play ball with such rubber and both not easily manufacture the rotation of table tennis, also the not original rotation of malleable table tennis, and batting swing the bat direction should be consistent with face normal direction as far as possible.When ball just has direction of swinging the bat during rotation generally different from resultant direction originally, the rotation of different ball is also different, so the angle that when playing ball, face and hand brandish direction will be convenient to adjust change as required, when playing ball with this racket, racket and handle moulding are complementary with hand-type of holding bat, this not only makes good hand touch of holding bat, and also ensure that said essence is that face is to the multidirectional needs had an effect of ball above.Due to the flexibility that this racket is held bat, be both convenient to the conversion between different technologies, be also convenient to the integrated application of various technology.Play ball with this racket, be convenient to select locus different on ball flight path as striking point on the ball fast, be also convenient to form the complete tight attacking and defending space that parabola equally covers the other side.

The utility model penholder grip, because upper and lower handle bar is asymmetric to base plate, so can not the use of falling face.I a few years ago obtain two patents penholder grip there is up-down symmetry can the use of falling face, the object of design also aspires after perfection, but practices a large amount of is for a long time felt to have like a fish bone getting stuck in the throat, because the flexibility that panesthesia is held bat is inadequate, also be difficult to the most effectively have an effect and play ball, the moulding of racket fails to make to play ball to reach the effect of design pursuit, a slice dense fog at the moment, have passed through long-term and arduous exploration, within 1st, recognize suddenly that problem goes out wherein, also be the problem that has of most of pen-hold grip in the market in fact, in fact those rackets are not the optimum shaping of large ball epoch pen-hold grip, in line with the principle that every wrong will be righted, just there is new penholder grip of the present invention, the sensation of playing ball with the new racket of the present invention is especially as dispelled the clouds and see the sun, fully effective practice is verified, the moulding of this racket is superior and advanced, this also will more and more be put into practice confirm, because scientific law is objective, not with the subjective will of people for transfer, certainly, accomplish fluently table tennis and also need conscious applied mechanics rule.This racket still has bilateral symmetry, holds bat all applicable to right-hand man, and symmetry adds brokenly scarce just more beautiful, leaves some things undone, could do some things better.The whole hand of holding bat of this pen-hold grip has moderately recessed striking plate face, and being also equivalent to striking plate face is the palm extended forward, and using this racket player instead also will have accurately understanding also scientifically to train certainly to this, just can experience the power of playing ball with this racket.In a word, this racket is by the meticulous improvement to the throat of original penholder grip, upper handle bar and the moulding of lower handle bar, have adjusted the method for holding bat of pen-hold grip dexterously, thus improved the quality of pen-hold grip at diverse location, different batsmanship, enhance and directly hold overall attack and defense ability, hold technique and tactics for ping-pong and opened up broad road in development under the new situation, also directly hold new achievement established the reliable foundation stone of science for casting.
