Description

Ping-pong bat

The present invention particularly relates to the new-type ping-pong bat of table tennis motion for relating to sports apparatus, and purpose is fully played on hand strength and dexterity in order to strengthen the function of racket.

Present table tennis bat, generally acknowledge to exist following point:

One, pen-hold grip

1, tapping gimmick changes too greatly, and the two is difficult to take into account, and can the person of attacking can not keep, and the kind person of keeping is not good at attacking.

2, backhand attack and clap shape and can not regulate and put in place, the attacking driving action is hindered by health, can not utilize wrist power to lift.Therefore attack on both sides person is rare, almost leave no successor.

3, middle far from the table lacks attack, in case the far from the table is at a stalemate in entering with the shake-hands grip player, just only lifts the merit of frame and does not have strength to hit back.

Two, shake-hands grip

The platform endosphere has been difficult for plate, and the attacking driving of forehand close-table lacks strength, and positive and negative hand can not push and block, and middle road body-hit is hard put to cope with the situation, and positive and negative hand can not high-order chop or the like.

The main cause that causes the problems referred to above so be its reason where? mainly be some common rules that existing table tennis bat and corresponding hold thereof have been run counter to human use strength.Now lifting its important person's example states as follows:

1, will bring into play certain strength (refer to power, wrist power, arm strength, wave arm strength or the like) necessity and ask hand to make correspondingly shape, the beginning can be given full play to it.Otherwise, when hand has already made certain shape, just stipulated that it can only bring into play certain strength with dexterous.

2, strength can the person of giving full play to, also must break out, and about the principle of breaking out power be: before not having an effect, finger, wrist, arm and even whole health all must extremely loosen, only accomplish loosening extremely, just can accomplish unexpected breaking out.

3, strength must be by certain power transmission point or power transmission position on hand, the beginning can accurately, whole passing.

4, in pen-hold grip, the size of distance between thumb and the forefinger is directly proportional with the performance that refers to power, and is inversely proportional to the performance of wrist flexibility.Refer to that power is big when promptly distance is big, the wrist flexibility is little, and distance hour finger power is little, and the wrist flexibility is big.

5, in pen-hold grip, when distance between thumb and forefinger when moderate (neither big nor small), pincerlike size is directly proportional with the performance of wrist power, and is inversely proportional to the performance of waving arm strength.Wrist power is big when promptly pincerlike big, and it is little to wave arm strength, and pincerlike hour wrist power is little, and it is big to wave arm strength.

6, in tennis grip, thumb, forefinger enter the depth of face, are directly proportional with the performance of strength, and are inversely proportional to the performance of finger, wrist flexibility.It is big promptly to enter when dark (holding deeply) strength, and flexibility is little; It is little to enter when shallow (shallow holding) strength, and flexibility is big.

Above rule is not done detailed explanation because of the length problem.

By article one rule as can be known: the shape that finger is made is that hold must be that the various strength of diversified competence exertion is to adapt to the needs of various different batting.

By the second rule as can be known: holding bat must be easily, can not be because of holding racket and paying meaningless grip.

By the 3rd rule as can be known: bring into play certain strength, necessity asks on hand correspondingly power transmission point or power transmission position to contact with racket.

By the 4th rule as can be known: the distance between thumb and the forefinger must be adjustable, desires greatly then greatly, and desire is little then little.

By the 5th rule as can be known: pincerlike size must be adjustable, wants just to stretch and stretches, and wants to contract and just contracts.

By the 6th rule as can be known: the depth that thumb, forefinger enter face must be adjustable, dark just dark, shallow just shallow.

As mentioned above, existing as can be known racket existing particular problem as follows:

One, pen-hold grip

1, dumb

Thumb lower platen during forehand attack, the forefinger perk, forefinger lower platen when backhanding attack, the thumb perk, but its hold does not have much changes, and only thumb, forefinger upwarp skid plate at two shoulders of clappers.Therefore limited to the adjusting of clapping shape, forefinger is made great efforts come what may, and desired tilt angle in the time of can not being adjusted to backhand to bat shape causes wrist, arm need twist with auxiliary adjustment and claps shape, be in not nature, thereby shot loses shape.This is that backhand is hindered by health why, the main cause of why can not play well.

Hold can not random variation, and because of clappers are firmly clamped by thumb, forefinger, middle finger, because clappers are too thin, so must exert oneself constantly, careful everywhere, it is slack to have slightly.So respectively refer to look out for yourself, dare not move, dare not become, be tantamount to spin a cocoon around oneself, haul oneself willingly into the net, consequently except self hold intrinsic some flexibilities, other existing on hand flexibility is all abandoned as spacious shoe, exhausts.

Handle is too thick, and filling does not have movable leeway among tiger.Racket can only be a left and right sides tilting with handle, dare not go one step beyond the prescribed limit, and is in a dilemma, as is the jail.

The position of centre of gravity of racket is too forward, and finger loosens slightly when swinging the bat, and racket just can fall, so respectively finger is made great efforts simultaneously, racket is held on to, and has on one's mind in " hand ", when no or release.

As above-mentioned: Bao base plate excessively, dull hold, too thick handle, forward center of gravity is to cause existing pen-hold grip to lack the main cause of flexibility.

2, powerlessness:

At first, pen-hold grip can not be brought into play the power of breaking out effectively, has run counter to above-mentioned second rule, because racket had not both had barrier just by thumb, forefinger, middle finger clamping, does not also have obstruction, very easily sells when waving arm.Therefore finger is necessary for and prevents that racket from slipping out of the hand and carefully watch out for, and is very urgent, be in ready for battle, heightened security posture.Both wasted strength, made again that the principle of the power of breaking out was destroyed, because in tension muscle can not break out in sudden contraction, so that the pen-hold grip batting has only is light, the branch of weight and significantly do not delay, suddenly; Loosen, break out other.

Moreover, because grip is changeless, run counter to above-mentioned first, fourth, 53 rule, can not be with difference of required strength appropriateness change hold, consequently or power do not capture, perhaps have too much of a good thing, can not be handy, follow one's inclinations.

For example: no matter adopt any grip, or hold deeply, or shallow holding, or middle pincer, big pincer, little pincer, or Japonica type or the like, all can only bring into play a certain strength more fully, can not take into account other.Only be suitable for bringing into play wrist power such as middle pincer, can only play close-to-table fast attack, just lack attack behind the destage, the ball of fighting back the other side has been an arrow at the end of its flight--a spent force, and power can not be worn the Shandong thin white silk used in ancient China.As for Japannish small forceps shape hold, because forefinger fastens handle, racket can not slipped out of the hand, so can bring into play more fully on middle far from the table and to wave arm strength, but close-table lacks strength, because close-table needs wrist snap, in any case and small forceps shape grip is also can not tremble.

Secondly, because hold is changeless, therefore finger also is changeless with the contact point of face, so exist strength and dexterous waste problem.Whether these contact points are better or desirable power transmission points because let us not go into the question now, even be of no avail, because these points are forced to select, and never only this counts some power transmission point on the thumb, forefinger, middle finger or power transmission position.

For example: middle pincerlike hold, forefinger, middle finger can only work to racket from the side, and its front promptly refer to tripe one side do not have due to its usefulness.Particularly during backhand, the thumb perk refers to that the tripe position is unsettled, its button is clapped strength and yielded, and is weak and lost holding bat of thumb strength, and is inconceivable, what also talks glibly about under these circumstances, and to accomplish fluently backhand just can only be to talk " ping " on the paper, and Chinese scholartree has been pacified a dream.

Two, shake-hands grip

1, dumb

If adopt the formula of clenching fist holding handle, then racket can not rotate, and extremely claps one.So thumb, forefinger stretch into face, clap shape (angle that racket tilts) so as to regulating.But thumb, forefinger already enter face, and then clappers just can only be done the little variation of amplitude between tiger, compare with the former, are not very different from, and one who retreats fifty paces mocks one who retreats a hundred.

In a single day thumb, forefinger enter face, just have no chance with handle, having only remaining middle finger, the third finger, little finger of toe is that muscle of hypothenar is held handle with palm, and must tightly hold, thereby racket can only be with the handle axle rotate in slightly between the tiger, be tantamount to the salamander of fence Li Zhi Yan, chize.

The position of centre of gravity of racket is too forward, refers to respectively and must exert oneself constantly just can catch racket that the problem of this point and above-mentioned pen-hold grip is identical, and is only even better.

2, powerlessness

Thumb, forefinger enter face, have just lost the power that mutual pincers are held, middle finger usually with thumb, forefinger common " trials and tribulations ", in case abandoned, just the orphan refers to difficult ring, and is unable to do what one wishes.Therefore in fact shake-hands grip has only handle half, and being that hypothenar is amyasthenic by nameless, little finger of toe and palm is just gripping, and vigorous and powerful strong thumb, forefinger, middle finger have been laid aside and neglected, and no scope for displaying one's abilities.

Know that pen-hold grip just can stand facing each other with shake-hands grip mutually simply by virtue of the strength of thumb, forefinger, middle finger, though and shake-hands grip seems to be the five fingers and holds bat, in fact have only the third finger, little finger of toe and muscle of hypothenar in ploughing and weeding quietly.In view of this, current so-called pen-hold grip and shake-hands grip, only internal strife, only first three items: thumb, forefinger, middle finger and back three: a time consuming the throne battle between the third finger, little finger of toe, the muscle of hypothenar.

Moreover, owing to thumb, forefinger have been castles in the air, therefore want to change constantly not only difficulty of hold, and unnecessary.Shake-hands grip is just as pen-hold grip like this, run counter to above-mentioned use strength first and second, six or three rules; Because the strength that lacks finger is with dexterous, so the platform endosphere has been difficult for plate, the close-table forehand attack lacks strength, and middle road body-hit is difficult to deal with; Again because to clap deformationization limited, so positive and negative hand can not push and block, positive and negative hand can not high-order chop or the like.In a word, variety of issue survivor therefrom there's no one who doesn't or isn't.And under such state, want to make strength and dexterity to incorporate things of diverse nature, and exhaustive, just can only be fruitless attempt, ask lady's-grass wantonly.

Combine as above-mentioned, no matter visible pen-hold grip or shake-hands grip, the needs of wanting to deacclimatize various different play with a kind of changeless grip are impossible.Accomplish omnipotently, must accomplish at first that ten thousand become, give up that there is no alternative outside this.

The present invention is and solves the existing variety of issue of above-mentioned existing table tennis bat and the designer.The present invention is made of following position:

Do 2 explanations earlier:

1. each position in each position, particularly handle of the present invention all is that indivisible integral body, the especially spheroid (1) of a unification and the connecting portion between the middle thin handle (2) more are provided with line of demarcation accurately.The present invention adopts the straight line split plot design that each position is distinguished, and just for the convenience in the clear and narration on directly perceived, figure in kind then should be an one integrated mass.

2. the present invention is not a precision instrument, and is not high to the difference requirements of the degree of accuracy, data and ratio, thus each position and the present invention have slightly come in and go out and in appearance to the similar substantially person of the present invention, all belong within the right protection scope of the present invention.

One, pen-hold grip

(with face one side is down under the handle, down with) be one substantially (because of some enters clappers, separated by clappers, and separated both sides can be asymmetric, so the cloud cardinal principle) spheroid (1) of spheroid or part is not (because of having line of demarcation accurately with the thin handle in the centre of top (2) when being connected, some coincides with it or is covered by it, so will or coincidence or cover part can be regarded as in the middle of thin shank portion), the contour shape in horizontal (paralleling with the face) vertical section at spheroid (1) center by this spheroid or part is that an ellipse or top are straight line (Fig. 1 (1), Fig. 6 (1)) or arbitrarily lines (Fig. 4 (1), Fig. 9 (1)), other is the ellipse of major part, the contour shape in its vertical (perpendicular) vertical section with face be one oval or by two half (veneer before, two sides---holding pen-hold grip with the right hand is example in the back, before the one side of forehand stroke is, otherwise being the back) symmetry or the asymmetric any lines that outwards protrude are generally constituted, these lines can be ellipse or arbitrary curve (Fig. 2 (1) of part, Figure 15 (1), Figure 17 (1), Figure 19 (1)) or make up lines arbitrarily (as the top is one section straight line, it is downwards the curve that outwards protrudes, upwards or directly or be connected with top straight line or the promptly middle thin handle (2) of any lines with one section curve) (Fig. 7 (1) is (1a), Figure 10 (1) (1a), Figure 17 (1) (1a), Figure 19 (1) (1a), Figure 21 (1) is (1a)) or the like, but the vertical diameter of the contour shape that it constituted (perpendicular with face) must be made progress by the center, down two sides dwindle (top be a section of straight line except) gradually, match to next dwindling gradually with bottom with the ellipse in horizontal vertical section, upwards then dwindle gradually with the straight line of the top of the ellipse of the ellipse in horizontal vertical section or part or lines (Fig. 2 (1) that is connected arbitrarily, Fig. 5 (1) Fig. 7 (1), Figure 10 (1)), the contour shape in the cross section at spheroid (1) center by this spheroid or part is constituted by an ellipse (Fig. 3 (11)) or by two half symmetry or the asymmetric any lines that outwards protrude generally, these lines can be ellipse or arbitrary curve (Figure 16 (11) of part, Figure 18 (11), Figure 20 (11)) or make up lines arbitrarily (as front or rear or preceding, back top is one section straight line, both sides are the ellipse or the arbitrary curve of the outwards part of protrusion) (Fig. 8 (11) is (11a), Figure 18 (11) (11a), Figure 20 (111) (11a), Figure 22 (11) is (11a)) or the like, its trans D (paralleling with face) is with laterally the ellipse in vertical section or the oval-shaped left and right sides diameter of part match, its vertical diameter (perpendicular with face) matches with the vertical diameter oval or other shape in vertical vertical section, this horizontal stroke, vertically the footpath upwards, two sides dwindle (preceding gradually down, back top respectively is except a section of straight line), to next dwindle gradually with horizontal stroke, the bottom of the ellipse in vertical vertical section or any lines matches, upwards then dwindle gradually with horizontal stroke, the straight line of the top of the ellipse in vertical vertical section or the ellipse of part or any lines match, the top of the spheroid of this spheroid or part (1) is connected with the thin handle in centre (2) in any suitable manner, by thin handle (2) center, this centre (as for recessed arc person then the thinnest place be the center) the contour shape in cross section be an ellipse (Fig. 3 (12), Fig. 8 (12)) or other arbitrary shape (figure slightly), but it is long, short diameter must be significantly less than the length in spheroid (1) cross section of spheroid or part, short diameter, because of being connected with the spheroid (1) of oval cylinder (3) and spheroid or part, so length in its cross section, short diameter upwards, following two sides increase (except one section in the straight line) gradually and are connected until the spheroid (1) with oval cylinder (3) and spheroid or part, therefore the contour shape in the vertical section (horizontal or vertical) by its center is last, under be straight line or any lines (Fig. 1 (2), Fig. 2 (2), Fig. 4 (2), Fig. 5 (2)) horizontal stroke, perpendicular both sides except that with spheroid (1) coupling part of spheroid or part, be essentially inwardly recessed camber line or other various any lines or make up lines (Fig. 1 (2) arbitrarily, Fig. 2 (2), Fig. 4 (2), Fig. 5 (2), Figure 11 (2), Figure 12 (2), Figure 13 (2), Figure 14 (2), Figure 15 (2), Figure 17 (2)), the top of the thin handle in this centre is connected with an oval cylinder (3) or any cylinder (figure slightly), by this ellipse cylinder (3) or arbitrarily the contour shape in the cross section at cylinder center be an ellipse (Fig. 3 (13), Fig. 8 (13)) or other various arbitrary shapes (figure slightly), this ellipse cylinder (3) or any cylinder differ and are decided to be vertical roller shaped, or it is wide at the top and narrow at the bottom, or up-narrow and down-wide person all can (scheme slightly), the top of oval cylinder (3) is furnished with center of gravity adjusting device (4) (Fig. 1 (4), Fig. 2 (4), Fig. 3 (14)), promptly be furnished with bigger material of proportion such as heavy metal thin slice (gold, silver, copper, iron, tin or the like) with the position person at appropriate regulation racket center of gravity place.

Two shoulders of racket are that the both sides base plate of spheroid (1) respectively has an inwardly recessed recessed shoulder of the recessed shoulder in left side (5) and right side (6) (holding the bat with the right hand is example, down with), and the recessed shoulder in both sides is asymmetric, and its shape also is not quite similar.The recessed shoulder in left side (5) is not to hinder thumb by vertically changing into laterally promptly from the side spheroid (1) degree of being firmly, and big slightly or a little bit smaller slightly influence is little.The recessed shoulder in right side (6) is clasped spheroid (1) degree of being together from the side with the thumb that does not hinder forefinger, middle finger and left side, a little bit smaller or big a bit all can, even depression also can not.Because depression is not the smaller several years of bat shape that can be adjusted to when adopting backhand grip at most.Yet the angle that can be adjusted to has been enough even more than sufficient for the needed bat shape angle of backhanding attack.

Two, shake-hands grip

Present shake-hands grip and pen-hold grip there is no much differences in shape, and only the shake-hands grip handle is long, and the pen-hold grip handle is short, the shake-hands grip double spreading, and pen-hold grip one side rubberizing--nowadays reverse penhold backhand, also double spreading.In view of this, in fact present table tennis bat there is no the branch of shake-hands grip, pen-hold grip, and so-called pen-hold grip is only simply directly held shake-hands grip.

The present invention uses as shake-hands grip, with current so-called pen-hold grip wonderful that " playing the same tune on different musical instruments " " reach the same goal by different routes " arranged, be that above-mentioned pen-hold grip is under the constant prerequisite of spheroid (1) in principal character, accidental quality (the recessed shoulder of left and right side (5), (6), middle thin handle (2)) given renovation slightly just can be used as shake-hands grip and used.Its scheme is as follows:

1, recessed shoulder in left side (5) and the recessed shoulder in right side (6) are made the shape of symmetry, and oval cylinder (3) is extended slightly, make entire length slightly get final product (figure slightly) mutually with the entire length of existing shake-hands grip.

2, the shake-hands grip after the above-mentioned renovation is deducted again in the middle of thin handle (2), be about to spheroid (1) directly with extend after oval cylinder (3) be connected (shape of junction is regardless of) get final product.(Figure 23, Figure 24, Figure 25, Figure 26)

As above-mentioned, as seen shake-hands grip of the present invention only deducts the promptly middle thin handle (2) of a feature on the basis of pen-hold grip, in this sense, shake-hands grip of the present invention is just simplified pen-hold grip of the present invention, just as present shake-hands grip, pen-hold grip, but not that shake-hands grip is directly held, but held pen-hold grip is horizontal.

What is interesting is, present shake-hands grip go out in Europe, the Asian takes back shake-hands grip is directly held, new-type pen-hold grip of now go out in the Asia, the European can reclaim and hold pen-hold grip is horizontal.

In addition, the present invention has done an improvement on the handle of new-type shake-hands grip, the second half section that is about to oval cylinder (3) makes the cross section and is criss-cross prism (Figure 27 (3a), Figure 28 (3a), Figure 29 (3a)), its objective is in the muscle that makes it to snap in muscle of hypothenar to increase the strength of lever.

The function and the using method thereof at each position of the present invention are as follows:

One, pen-hold grip

The present invention uses as pen-hold grip, then still is mainly thumb, forefinger, middle finger, the third finger, little finger of toe and tiger and manages.Different persons, the present canot compare with the past, and struggle among the chains of old-fashioned pen-hold grip in each position, and joy is gamboled, and sings and dances festively.

Each position of the present invention: spheroid (1), middle thin handle (2), oval cylinder (3), center of gravity adjusting device (4) and the recessed shoulder of left and right side (5,6) are though Each performs its own functions, but the indivisible integral body of a unification, good teamwork is complemented each other.Because thumb second knuckle (joint with the band nail is a first segment, down together) and root are pressed the thin handle in centre (2) gently, are placed among the tiger, its top is a barrier with thicker cylindroid these (3) again, so racket has not had the worry of selling.So do not have the thumb, forefinger, middle finger of burden just can be free rapidly within limits movable, though form various little variant and holds that effect is different.When pincer reclaims, when middle finger is placed in the lower end of spheroid (1), racket does not more have the anxiety of selling, so thumb, forefinger, middle finger when entangling spheroid (but still move left and right) again can be free within limits movable, forming again still is the different diversified hold of little variant and real flavor.With the former addition, be countless.

The feature of backhand grip of the present invention is: thumb is exerted oneself to handle by vertically handle firmly being changed into laterally, be thumb refer to tripe from the side of spheroid (1) or top to right rotation 90 degree, laterally directly to spheroid (1) and be pressed on the arc tripe that its side protrudes, this moment middle finger, forefinger is also clasped spheroid (1) with its front, middle thin handle (2) is then taken advantage of a situation and is moved forward on the third knuckle of forefinger, do not fettered already by tiger, this moment, each finger was in the needed nature of backhand, state easily, racket is horizontal in billiard table, handle even downward-sloping, therefore racket does not more have the trouble of selling, and thumb presses down spheroid (1) from the side, the scope that exceeds needs can be transferred in the angle of inclination of racket, reach the angle of even hypsokinesis parallel with table top, more oblique than shake-hands grip, more horizontal than shake-hands grip.

Certainly, backhand grip also also nonessential with thumb by vertically changing into laterally directly and can not to spheroid (1).When adopting other hold, also have and to clap the shape appropriate regulation and carry out backhand person, so the hold during backhand also remains diversified.

If, be to be difficult to add up with the addition of enumerating in full detail of above-mentioned forehand, all various holds of backhand.Even if also be not titled with Protean title.

As mentioned above, racket had not both had the anxiety of selling, and hold just can be changeable, and respectively finger (thumb, forefinger, middle finger) can not only be detained bat from the side, also can render a service from the front.Brandish up and down, as boundless as the sea and the sky.Combination as for what attack and defense; Break out the performance of power; Distance between thumb, the forefinger; Pincerlike flexible or the like be nothing difficult already has been not worth mentioning in face of fast changing diversified hold.

Center of gravity adjusting device (4) is to implement the important leverage of the every function of the present invention.Be adjusted to desirable position because have only when center of gravity, both do not had top-heavy anxiety, when also not having the worry that the pin countersunk head wafts, each position beginning can be without fear of an attack from the rear, and indiscriminately ad. as one wishes changes fully to put the energy of himself to good use rapidly.

Just because of hold is ever-changing, the present invention still has many extremely mysterious and abstruse profound parts not state to the greatest extent one by one.The user ought slowly sample, and finely ponders.In case pass through the hall into the inner chamber, cross over many wonderful doors, just can be masterly, extremely miraculous.

Two, shake-hands grip

The present invention uses as shake-hands grip, already more towards the replacement, changed beyond recognition: thumb, forefinger, the middle finger of having been dethroned are heavily stepped on the throne, again the sink-float of cue ball bat: because handle gos deep into face, thumb, forefinger just can tightly be clamped spheroid (1), just because of clamped handle, thumb, forefinger can be to move freely: from deep to shallow, from shallow to deep, fast or slow, by fits and starts; Again because respectively there is a pore belt (the recessed shoulder of left and right side (5), (6)) both sides of spheroid, therefore no longer stopped when thumb, forefinger, middle finger rotational ellipsoid together (1) for having the final say, spend wheel but can do 360; Moreover, because spheroid (1) can freely gallop for thumb, forefinger, middle finger: or folder or embrace or pocket or push away or pinch or overlap,, like the shadow following the person as fish like water; Particularly center of gravity adjusting device (4) make racket no longer simple be that axle rotates between the tiger with the handle, but can be axle, forward backward with spheroid (1), left to the right, dance lightly to multi-faceted, the same just like pen-hold grip, be to brandish up and down equally, as boundless as the sea and the sky; Be ever-changing, boundless equally; Be extremely mysterious and abstruse equally, many wonderful doors; Be masterly, extremely miraculous equally.

Combine as above-mentioned, the present invention no longer is confined to solve within the category of the problems that have racket now, but the table tennis Nirvana has obtained new life among the raging flames that old-fashioned racket is remoulded oneself thoroughly.

So we see: by a kind of to multiple, by not changing to ten thousand changes, by cicada's wings to thousand an ancient unit of weight, by haze to bright--we have welcome in the table tennis New World one finally and have taken turns the Chaoyang of emerging in all its splendour.

Accompanying drawing 1,2,3 is for the master of new-type straight racket for ping-pong ball looks, side-looking, look up exemplary plot.Among the figure: the thin oval cylinder of handle (2) (3) center of gravity adjusting device (4) the left side recessed shoulder in recessed shoulder (5) right side (6) covering (sponge, micelle etc.) shape figure (7) in the middle of the spheroid (1) of veneer (10) spheroid or part.

Size of the present invention is its whole length, width and existing racket are roughly the same, each position both can be bonding, it also can be one, rounding off is answered in the junction, leave no trace, the surface of whole handle can make concavo-convex alternate, crisscross various textures, a left side, the recessed shoulder in right side ((5), (6)), middle thin handle (2) is not to hinder thumb, forefinger, middle finger is clasped spheroid (1) from the side and is degree, should not cross dark or meticulous, center of gravity adjusting device (4) the just appropriateness weight that increases the weight of the handle upper end is a purpose to reach appropriate regulation racket center of gravity position, material for adjuster, size, shape, thickness, weight etc. are not limit, methods for the increase and decrease adjuster also are regardless of, or exposed conveying appliance (directly being added on the handle top), or built-in (being set within the handle) all can, the increase and decrease mode is based on screw tightening, and other is as bonding, absorption or the like also can.Material therefor of the present invention is regardless of, and is not high to the difference requirements of the degree of accuracy, data and ratio, and discrepancy can be arranged slightly, and when varying with each individual, is put to produce, and the difference of big ting model then should be arranged.

Claims (6)

1, a kind of ping-pong bat, it is characterized in that: under the handle be one substantially spheroid or the spheroid (1) of part, the contour shape in the horizontal vertical section that parallels with face at spheroid (1) center by this spheroid or part is that an ellipse or top are straight line or lines arbitrarily, other is the ellipse of major part, the contour shape in the vertical vertical section that itself and face are perpendicular is oval or be made of the two any lines that outwards protrude generally for half by one, the perpendicular span of itself and face is made progress by the center, two sides dwindle gradually down, the contour shape in the cross section at spheroid (1) center by this spheroid or part is oval or be made of the two any lines that outwards protrude generally for half by one, it parallels with face and vertical horizontal stroke, vertical pivot is made progress by the center, two sides dwindle gradually down, the top of the spheroid of this spheroid or part (1) is connected with the thin handle in centre (2) in any suitable manner, by the thin handle (2) in this centre the contour shape in the cross section at the center at thin place be an ellipse, but it is long, minor axis is significantly less than the length in spheroid (1) cross section of spheroid or part, minor axis, because of being connected with the spheroid (1) of oval cylinder (3) and spheroid or part, so length in its cross section, minor axis upwards, descending two sides to increase gradually until the spheroid (1) with oval cylinder (3) and spheroid or part is connected, therefore the contour shape in the vertical section by its center is last, under be straight line, horizontal, perpendicular both sides except that with spheroid (1) coupling part of spheroid or part, be essentially inwardly recessed camber line, the top of the thin handle in this centre is connected with an oval cylinder (3), and the contour shape in the cross section by this ellipse cylinder (3) center is an ellipse.

2, a kind of ping-pong bat, it is characterized in that: under the handle be one substantially spheroid or the spheroid (1) of part, the contour shape in the horizontal vertical section that parallels with face at spheroid (1) center by this spheroid or part is that an ellipse or top are straight line or lines arbitrarily, other is the ellipse of major part, the contour shape in the vertical vertical section that itself and face are perpendicular is oval or be made of the two any lines that outwards protrude generally for half by one, the perpendicular span of itself and face is made progress by the center, two sides dwindle gradually down, the contour shape in the cross section at spheroid (1) center by this spheroid or part is oval or be made of the two any lines that outwards protrude generally for half by one, and it parallels with face and vertical horizontal stroke, vertical pivot is made progress by the center, two sides dwindle gradually down.

3, ping-pong bat as claimed in claim 1 is characterized in that: the oval cylinder (3) on the handle can be the awl cylinder.

4, ping-pong bat as claimed in claim 2 is characterized in that: the second half section of the handle that is connected with the spheroid (1) of spheroid or part is that section is criss-cross prism [Figure 27 (3a), Figure 28 (3a), Figure 29 (3a)].

5, as claim 1 or claim 2 or claim 3 or the described ping-pong bat of claim 4, it is characterized in that: two shoulders of racket are on the base plate of spheroid (1) both sides of spheroid or part an inwardly recessed symmetrical or asymmetric recessed shoulder of being regardless of shape to be arranged respectively.

6, as claim 1 or claim 2 or claim 3 or claim 4 or the described ping-pong bat of claim 5, it is characterized in that: the upper end of handle is that the top is equipped with center of gravity adjusting device (4).
