A kind of penholder grip.There is the throat of peach tip type at the striking plate position that is connected with handle.Handle by paste with the integrally formed handle of the wooden base plate extension of striking plate and respectively thereon, the upper and lower handle item of lower surface forms.Upper handle item is shorter than lower handle item, and front end can only approach but cannot protrude into inside throat, and upper handle middle and back is thicker, gradually thinning from middle part to front end.Lower handle item is longer than upper handle item, and front end is put in inside throat, and lower handle item is whole thin compared with upper handle item, and middle part is most thin, and interior thickness is suitable with the sponge and rubber thickness that lower surface of base plate is pasted, and front end is slightly thicker than middle part, and rear end is again slightly thicker than front end.The upper and lower handle item of handle is along central axes bilateral symmetry, and thick by central axes, two sides are thin, and for upper and lower handle item to bottom plate asymmetry, handle surface is curved surface.This racket overcomes after table tennis uses the big ball of diameter 40+mm instead and directly holds the various problems faced, and providing one kind holds smoothly comfortably, and batsmanship unfolds smoothness, the stronger novel penholder grip of attack and defense ability.

Description

Penholder grip

One, technical field

The present invention relates to a kind of table tennis bats.

Two, background technique

Table tennis bat has Chinese pen-hold grip, the square pen-hold grip of Japan and South Korea, shake-hands grip and other New rackets etc..China is existing Penholder grip be made of striking plate and handle, handle is by being made integrated handle with bottom plate and being respectively adhered on handle The handle item of upper and lower surfaces is constituted, and cross section is oval, and the nose thickness of handle is less than the tail end thickness of handle, upper and lower handle Strip is the same and opposed bottom central plane is symmetrical, and Chinese's popular feelings of industry and intelligence can be made by being played ball with the racket of such moulding The skillful with one's hands feature of spirit is able to give full play to and show when playing table tennis, uses the bead epoch of diameter 38mm in table tennis, use The play of this racket backhand block with forehand also had brilliant military success really in international tournament, now still largely existed in the market, and It is widely used by paddler and fan.After on October 1st, 2000, table tennis uses diameter 39.50-40.50mm instead Big ball, from July 1st, 2014, table tennis diameter again on be transferred to 40.00-40.60mm, material is changed to by original celluloid New plastics, by bead to big ball, the diameter of table tennis increases about 5.3%, and volume increases about 18%, the matter of table tennis Amount becomes 2.7g from 2.5g, increases 8%；The formula of the rotary inertia of the spherical shell of uniform quality distribution is (2/3) mR², so Table tennis is changed the rotary inertia after big ball by bead and increases 20% or more, though what the big ball that we get need to only maintain to get The speed and rotation of bead, it is also desirable to provide more translational kinetic energies and rotational kinetic energy to table tennis, that is to say, that impact In more function are done to table tennis.Since the increase of rotational inertia of table tennis ball is more, manufacture and the rotation for changing ball become more It is difficult.After using big ball instead, speed when being on the one hand table tennis delivery is not easy to reach big like that when bead, while also because of table tennis Suffered air drag increases when ball flight in the sky, and velocity of shuttle flight slows down, so the rhythm played ball is slack-off, this is to me Cope with ball and leave more times, can more fully Grounding.Above situation shows to play table tennis by doing petty action The probability for making score becomes smaller, and directly holds push and block technology if being critically important in the bead epoch and having it rationally and apodictic It talks about, and in the big ball epoch, it should be just effective with the ingenious cooperation of other technologies, cannot only consider that push and block are beaten without focusing on disappearing on drawing now Etc. other technologies, push and block can not be treated as the unique technical directly held or whole technologies, this primary level only directly held is another Aspect, pen-hold grip abandon push and block completely, either with former pen-hold grip from other trials in play, or other the setting of new racket moulding Meter is all a lack of the performance of Materialist Dialectics method, also all not successful enough in practice, directly hold improved critical issue be as What is reasonably accepted or rejected, and the big ball epoch, which play ball, needs big gimmick, and score must have more strong means.It is anti-when people play ball Speed (reaction time) is answered to have the limit, the performance to have had in play is gained the initiative, and keeps the ball got more excellent, visitor Needing in sight can in time with racket square stance, and scientifically and rationally face is controlled in adjustment, and can substantially effectively be had an effect, and can just be made The placement that must be got is more quasi-, sells faster, and ball speed is bigger, and rotation is stronger, and variation is more.World table tennis organization decided will rattle Ball is changed to the big ball of diameter 40mm by the bead of diameter 38mm, increases the ornamental value of ping-pong contest, to a certain extent and The needs of table tennis development, but the suspicion for also having foreign country to suppress China are small because the strength of Chinese table-tennis movement is too strong Ball changes big ball and existing pen-hold grip backhand difficulty is attacked, and forehand vacancy is big, looks after that face is small, and stability is poor, and locked ability is weak etc. original lacks Falling into becomes more prominent, national ball game of the table tennis as China, in several ten million even 100,000,000 crowds to play table tennis, with pen-hold grip person And it is not within minority, play be also with their own characteristics, it is colourful, however it is true directly not hold person in high-caliber paddler now It is real seldom, this can't but be the inherent shortcoming of existing pen-hold grip to performances of sportsman's potential restricted as a result, rattling The big ball epoch of ball movement need directly to possess update, more scientific and reasonable, more advanced practical play, the improvement and upgrading of pen-hold grip When the replacement has arrived very urgent.Japan, the rectangular pen-hold grip of South Korea, opposite moulding when holding bat between hand and bat are solid Fixed, though froehand-backhand attacking driving convenient for having an effect, is looked after, face is big, and hand-type of holding bat is relatively fixed, and the adjustment of face is inflexible, it is inconvenient and When scientifically and rationally cope with the ball of different location, different performance.In recent years the Patent No. including my invention occurred Numerous bat of table tennis including ZL99204508.8 and Patent No. ZL200420014133.6 are football fans to original straight There are a kind of reactions that problem has common recognition for bat, and never Tongfang faces the positive beneficial exploration that racket carries out, though each tool spy Color, but recognize and also have various deficiencies on designing, satisfactory not enough, user is few, in the market also seldom.Westerner uses Knife and fork dining, plays table tennis with shake-hands grip, and horizontal froehand-backhand of holding can preferably be had an effect, and looks after that face is big, and the middle locked ability in far from the table is strong, but just Backhand exchange batting switches face and needs the time, weaker in the platform of Road.Asians eats with chopsticks, and plays table tennis multi-purpose straight It claps, directly holds the reflection for being the eastern civilization in table tennis, the Chinese nation is the nationality for being good at thinking deeply and learning, Chinese civilization The civilization that can and be good at using for reference and absorb all other outstanding civilized achievements since bead change be conducive to horizontal hold after big ball and It is unfavorable for directly holding, we will carry out objective science to original pen-hold grip and analyze practically, and dialectical negative is taken to sublate Viewpoint, retain its rational factor, eliminate its unfavorable obstacle, and consciously learn and draw horizontal the advantages of other rackets such as holding And its weakness is avoided, the moulding of improve and perfect pen-hold grip could effectively promote the function of pen-hold grip, enhance pen-hold grip under the new situation Vitality, and create ping-pong again and hold the new splendidness of play, to carry forward my the eastern civilization.

Three, summary of the invention

It is an object of the invention to according to table tennis use instead diameter by directly held after the big baton round of 40+mm face it is new Challenge, by directly holding the improvement of bat handle and the moulding of throat position to existing, being in one's hands to clap hands is able to do delicate adjustment in shape, The shortcomings that overcome original pen-hold grip, simultaneously develops its advantage, provides a kind of new penholder grip, holds comfortably smoothly, flexibly steady It is fixed, when playing ball both face easy to adjustment in time in place, be also convenient for it is scientific and reasonable, substantially effectively have an effect, middle in treatment bench Enough flexibly, straight-holding and horizontal-beating strong applicability, it is big to look after face, locked steady, reaction faster, play ball it is more quasi-, more ruthless, more turn, change More, attack and defense ability is stronger, more excellent good-looking penholder grip of taking part in the match.This racket invention purpose lie also in by It mutually reflects in hand shape of holding bat and play with mutual of other rackets such as shake-hands grip, is directly held under the new situation to the reality of other rackets with improving War ability.Because of mainly Chinese's Chinese style pen-hold grip, the present invention can be existed also for Chinese table-tennis team team member with this racket Better achievement is obtained in international tournament.In short, the invention of the utility model table tennis bat is revitalized straight to preferably service football fan It holds, does credit to one's country, build dream China.Due to the upper and lower handle item and asymmetry of this bat handle, so unsuitable stopping surface uses.

Penholder grip of the present invention is made of striking plate and the handle being linked together with striking plate.Striking plate is essentially Ellipse has apparent peach tip shape throat, i.e., is by the front end of the supreme handle item of bat shoulder of striking plate between striking plate and handle It gradually narrows from the width, the throat part that striking plate is connect with handle is turned around shaped like peach tip shape to be connected with branch.Handle by The wooden base plate extension point two sides of striking plate bonds upper and lower handle item composition respectively.Upper handle item is shorter than lower handle item, before lower handle item Hold the opposite part of thick, upper handle item be exactly it is empty, upper handle middle and back is thicker, gradually becomes from middle part to front end Thin, shaped like splitter, front end can only approach but cannot protrude into inside throat, and handle rear end is wider, becomes narrow gradually forward, upper handle item two Side is symmetrical relative to central axes, thicker along central axes, and two sides are gradually thinning, and surface is smooth arc-shaped surface.Lower handle item is longer than upper handle item, Front end is put in inside throat, and lower handle item is whole thin compared with upper handle item, and middle part is most thin, and the sea that interior thickness and lower surface of base plate are pasted Tender rubber overall thickness is suitable, and front end is than slightly thick, 20 ° or so of the front end face inclination angle in middle part, and rear end is than front end and slightly thick, lower handle item two Side is symmetrical also relative to central axes, and thicker along handle central axes, two sides are gradually thinning, and handle rear end is most wide, and middle part is most narrow, surface For smooth arc-shaped surface.Since the upper and lower handle strip of handle is not identical, upper and lower handle item is to bottom plate and asymmetry.

Penholder grip of the present invention, lower handle front end is slightly thick compared with middle part and protrudes into throat position, ensure that batting plate face The intensity connected between handle will not be broken, while it limits hand of holding bat and cannot protrude into too much in batting plate face, in order to avoid Hinder the flexibility held bat.Sponge and rubber overall thickness relatively thin and with lower face are suitable in the middle part of lower handle item, and tiger's jaw exists when holding bat This position, it is ensured that middle finger coincide very well with face when holding bat, capable of expansion and contraction, while also reducing index finger when holding bat and referring to middle finger Angle between one section of root (even one section of palm), improves the entire comfort level held and clapped, and the sponge of lower face and rubber are total Thinner in the middle part of thickness and lower handle item, index finger and middle finger refer to that the angle between one section of root is just smaller when holding bat, and attack hand when disappearing lifting the ball It is also better to feel, so the thickness and lower handle interior thickness of sponge and rubber that lower face is pasted are all thinner preferably, certainly, under Plate face also non-sticking patch sponge and rubber only cannot thus be played ball with the anti-technology of beating directly is held.Upper handle item is short compared with lower handle item, on Handle front end and throat surface area be mother refer to index finger activity space, ensure that movable freedom degree between racket and hand, Which also eliminates former pen-hold grips to adjust obstacle not in place in froehand-backhand different location difference batsmanship square stance face.If The handle item of the penholder grip of the Patent No. zL200420014133.6 of the lower handle item and my invention of this racket has centainly If similitude, the front end mute of a handle item of common pen-hold grip previous section is allowed to shorten by that this racket, and surface is The curved surface of intermediate projections, and and this racket lower handle item combination moulding it is very crucial, this entirely to hold bat hand moderately Batting pan section has been recessed, the obstacle that handle front end rotates face is eliminated, holding this beating ball just has backward Hai Kuo The potential of the sense of its height, pen-hold grip is just released.Due to peach tip shape throat between the preceding feature and striking surface and handle of handle Moulding, when directly holding this racket, the third finger can both have been leaned against behind striking plate in refer to nearby assist control face, can also lean on naturally It is clapping near shoulder and throat on side, or even nameless finger is being exposed to control face, this is not only easier to adjust face In place, also sufficiently effective can more have an effect, when needing, it is nameless can also the tangential movement of boosting bottom plate, this penholder grip is not It is anti-to be referred to as new straight hold.The science of this pen-hold grip throat position and handle moulding adjusts the delicate variation for the shape that causes directly to shake hands, It is to be played ball the basic guarantee that quality is improved and improves with this pen-hold grip.Handle surface is all smooth curved surface to handle up and down, is guaranteed Opposite moulding between racket and hand of holding bat can consecutive variations, convenient for as needed, properly coping with different location different performance Ball.Lower handle rear end and upper handle middle and back are thicker, ensure that hold bat have enough stability.Racket and the new entirety of handle Moulding ensure that new racket directly holds good hand touch of playing ball, and shot unfolds smoothness.

Penholder grip of the present invention, due to the flexibility of face regulation, bead is good enough in processing Road, platform.With this Racket is played ball, and due to being identical for middle finger and face, having an effect for hand and claps direct to the direction of ball actual force one at direction It causes, to improve the accuracy that batting reaches target point, this is actually to eliminate to be played ball the side of having an effect of hand with tradition pen-hold grip Often there is an angle to force direction of the face to ball, says it is systematic error from the angle of experiment, this is not only An Advanced Idea in design, the even more true perception of thousands of times actual combat.Due to holding bat state striking plate naturally and arm exists On same straight line, convenient for making full use of " whipping effect " sufficiently to have an effect, the speed for getting ball can be improved.The third finger can boosting face Acceleration tangentially is swung, and can increase the rotation of ball.Since this directly holds racket racket can be protruded into only one finger i.e. middle finger The back side, the third finger naturally enough lean against bat point on throat side, and one finger of index finger is protruded into the hand of holding bat of face with horizontal hold by this Shape has similarity, and in the case where human body and little hand shape variation, the minor motion of finger can be easily by face tune Whole either translation or rotation, the smaller movement of finger can all drive face to have compared with big-movement ball in place, disappear to be promoted The quality of the batsmanships such as drawing is beaten, and is held bat smoothly, swings the bat and unfolds, so equally good, photograph is held with horizontal in froehand-backhand position and middle far from the table Gu face is big, and the locked ability of attacking and defending is all very strong.Certainly, with horizontal hold, with this racket serve a ball when, each finger all can deeply bat Racket is held in face deeply, and is had an effect with different hand shapes of holding bat, convenient for issuing the ball of different performance.Due to froehand-backhand position be mostly used it is same Striking surface batting, without converting face, so the reaction of froehand-backhand position conversion batting is held fastly than horizontal.Since the moulding of this racket makes directly The angle for holding by-blow becomes reasonable and adjustable, to expand the scope of application of straight-holding and horizontal-beating.During playing ball, it is also due to and holds Finger of clapping hands protrudes into that face is not bery deep, so that backhand ball with tow sides bats conversion easily naturally, if both sides face Sponge and rubber difference, the ball performance hit is also different, and the difficulty that can increase opponent's reply is used interchangeably suddenly.

Penholder grip of the present invention, design is based on the correct understanding to the Laws of Mechanics played table tennis.Face pair The elastic force direction of ball is perpendicular to face, and the direction of frictional force is along face, and bat has the direction of ball resultant force with face normal direction One angle, different rubber are different from table tennis coefficient of friction, so resultant direction is different from the angle direction of face, because quiet rub Wipe power between zero and maximum static friction force can be changed, so, i.e., played ball using same rubber, between resultant direction and face normal it Angle can be changed between zero and a certain maximum angular, be must occur eating ball phenomenon more than this maximum angular, i.e., ball not swing the bat by edge Direction is walked, this angle is critical angle, this critical angle is determined by the coefficient of friction of rubber, I measures in experiment, new The confficient of static friction of anti-glue rubber and table tennis is between 2.0 to 2.5, its critical angle is between 63 to 68 degree, i.e. resultant force side To angle minimum between face can to 27 to 22 degree, be commonly called as wipe ball it is very thin, here it is the designs of this racket to make from different perspectives Feel of holding bat reaches best reason, and between 0.1 to 0.2, it faces the confficient of static friction of some positive photoresist rubber and table tennis It is played ball with such rubber between 5 to 10 degree and is both not easy to manufacture the rotation of table tennis, also malleable table tennis is not original in boundary angle Rotation, and batting swing the bat direction should be as consistent with face normal direction as possible.Swing the bat when ball just has rotation originally direction with Resultant direction is generally different, and the rotation of different balls is also different, so the angle that face and hand brandish direction when playing ball will be convenient for root According to needing to adjust variation, when being played ball with this racket, racket and handle moulding with hand-type of holding bat be it is complementary, this not only to hold bat Good hand touch also ensures the substantially face needs having an effect multidirectional to ball said before.Due to the flexibility that this racket is held bat, Both convenient for the conversion between different technologies, it is also convenient for the integrated application of various technologies.It is played ball with this racket, convenient for quickly selection ball Different spatial positions is as hitting point on flight path, is also convenient for being formed paraboloid and equally strict attacks covered with the complete of other side Anti- space.

Penholder grip of the present invention, since upper and lower handle item is to bottom plate asymmetry, so being unable to stopping surface use.Before me A bit obtain in year two patents penholder grips have up-down symmetry can stopping surface use, the purpose of design is also to have pursued Beauty, but a large amount of practice for a long time feel to have it is like a fish bone getting stuck in the throat because the flexibility that panesthesia is held bat is inadequate, it is also difficult to most sufficiently It effectively has an effect and plays ball, the moulding of racket fails to make to play ball to achieve the effect that design is pursued, and a piece of dense fog, have passed through long-term at the moment Arduous exploration recognizes the problem of problem goes out wherein, and most of pen-hold grips have in fact and currently on the market on 1st suddenly, In fact those rackets are not the optimum shaping of big ball epoch pen-hold grip, in line with the principle that every wrong will be righted, just there is this new hair Bright penholder grip is such as dispelled the clouds and see the sun especially with the feeling that new racket of the invention is played ball, and sufficiently effective practice is it has been proved that originally The moulding of racket be it is superior and advanced, this also will by more and more practice confirm because scientific law be objectively, It is not transfer with the subjective will of people, certainly, accomplishing fluently table tennis also needs conscious applied mechanics rule.This racket still has left and right pair Title property, holding bat to right-hand man is all suitable for, symmetrical plus broken scarce just more beautiful, leaves some things undone, could preferably do some things.This pen-hold grip is entire Hand of holding bat moderately has recessed batting plate face, and also corresponding to batting plate face is the palm extended forward, uses this racket instead and plays ball Person will also have accurate understanding certainly to this and scientifically train, and can just experience the power played ball with this racket.In short, this racket By throat, upper handle item and the meticulous improvement of lower handle moulding to original penholder grip, pen-hold grip is dexterously had adjusted Hold bat method, so as to improve with improve pen-hold grip in the quality of different location, different batsmanships, enhance and directly hold whole attack Anti- ability holds technique and tactics and has opened up wide road in development under the new situation for ping-pong, also for cast directly hold it is new at Scientific reliable foundation stone is just established.
