Description

Can improve the football boot of the shooting degree of accuracy

The utility model relates to a kind of football boot.

From a large amount of football matches, the degree of accuracy of shooting and hit rate are all very low, the ball of sportsman shooting, more than 50% all directive outside the woodwork, can't produce the other side's goal at all and threaten.Even the shooting of threat is arranged, also can be not enough, that speed is unhappy, angle is not tricky etc. is former thereby caught by the goalkeeper because of strength, thereby the rate that scores the goal is just lower.The few mood of spectators' excitements and the excellence and glamour of match of having influenced scores the goal.

The low reason of the degree of accuracy and hit rate that causes shooting has very big relation with the football boot that adopt now.Existing football boot, its vamp shape is as the shape of people's pin.Because the instep portion of playing football is an irregular curved surface (seeing Fig. 1, Fig. 2), wear this football boot batting with irregular curved surface, be difficult to make the striking point on the ball B of reality and desirable striking point on the ball A to coincide, like this, even the swinging kick direction N4 of driver's reality and desirable swinging kick direction N2 are identical, ball direction of motion N6 a little 0 (the seeing Fig. 3, Fig. 4) that still can depart from objectives greatly because of the effect of the constraint reaction direction N5 that departs from placement point, this point can be learnt from " rational mechanics ".Rational mechanics points out that the direction of constraint reaction is to point to foreign side along obligatory point (as pin) in the normal direction at contact point place.N3 is the direction of motion of ball ideally among the figure, and N1 is a constraint reaction direction ideally.

Some is artificial to address the above problem, on football boot, make an issue of, as " football boot " (patent No. 96222169.4), " football boot " (patent No. 96249262.0), " Soccer shoe " (patent No. 91209646) etc. with gear sheet rubber, the purpose of these footwear is to improve the strength of shooting and the rotatory of ball by this kind football boot, improve the degree of accuracy and the hit rate of shooting with this, but they all do not consider the influence of constraint reaction.The applicant once designed " football boot that can improve shooting average " (application number 00114338.7), and it includes vamp 5, is positioned at the shoelace buckle at heel of a shoe place, shoestring 7, sole 4 and shoe tack 6, and vamp has footwear internal surface layer and footwear outer coversheet.Four batting planes are arranged on the footwear, it is the positive striking surface 3 on the instep, the medial and lateral striking surface 9,8 of instep medial and lateral, auxiliary striking surface 1 on the tiptoe, just, the medial and lateral striking surface is the rigidity striking surface, auxiliary striking surface is semi-rigid striking surface, and they are made by nylon 1010 class material, and its inboard natural shape with people's pin matches.

It is consistent with the ideal orientation that the sportsman is aimed at that the purpose of this utility model aims to provide a kind of suffered constraint reaction direction of ball that can make, can make the straight shot direction more accurate, increase the banana kick revolving force, can increase substantially the shooting degree of accuracy and hit rate, produce the football boot of more scoring opportunities.

The purpose of this utility model implementation is, can improve the football boot of the shooting degree of accuracy, includes vamp 5, is positioned at shoelace buckle, shoestring 7, sole 4 and the shoe tack 6 at heel of a shoe place, and vamp has footwear internal surface layer and footwear outer coversheet.Four batting planes are arranged on the footwear, it is the positive striking surface 3 on the instep, the medial and lateral striking surface 9,8 of instep medial and lateral, auxiliary striking surface 1 on the tiptoe, just, the medial and lateral striking surface is the rigidity striking surface, auxiliary striking surface is semi-rigid striking surface, and they are made by nylon 1010 or similar material, and its inboard natural shape with people's pin matches.These four batting planes are inclusive within the footwear outer coversheet, or are exposed to outside the footwear outer coversheet, are exposed to the coarse plane that batting plane outside the footwear outer coversheet can be the light face or increases coefficient of friction.When the batting plane is matsurface, increased the coefficient of friction of striking surface, can make the straight shot direction that hits more accurate, more stable, banana kick rotation radian is bigger.

The utility model is described in detail in detail with reference to the accompanying drawings.

The situation that ball may depart from when Figure 10 wore existing football boot with positive instep, placing the shot (when the swinging kick direction have ± during the error of α);

The situation that ball may depart from when Figure 11 wore the utility model football boot with positive striking surface, placing the shot (when the swinging kick direction have ± during the error of α);

With reference to accompanying drawing, four batting planes are arranged on these football boot, the positive striking surface 3 on the instep is a rectangle or approximate rectangular, and the medial and lateral striking surface 9,8 of instep medial and lateral is a triangle or subtriangular, and the auxiliary striking surface 1 on the tiptoe is an approximate half-circular.The angle on medial and lateral striking surface and sole plane is respectively 80 °-90 °, 50 °-60 °.Just, the medial and lateral striking surface adopts thick modified sheet metal or the similar material of 60Si2MnA of 0.5mm, steel plate wraps within nylon 1010 or the similar material 10, the rigidity and the intensity of striking surface had so both been guaranteed, steel plate can not contacted with your health, can not damage anyone.Striking surface also can be cancelled sheet metal or similar material, but the thickness m of instep top plastics thinnest part should be thickened to more than the 5mm by 2.5mm.Auxiliary striking surface adopts thin plastics or elastomeric material.

Positive striking surface 3 is the most important striking surfaces of sportsman, and the sportsman thinks " shooting of shell formula ", and its striking point on the ball is general all on this face.A line shown in Figure 7 must with the sole plane parallel, the auxiliary striking surface 1 of tiptoe top is mainly used in the positive shooting of sportsman or shoots in the way of overhead hook.One neutral gear 2 that footwear outer facing material and footwear inner facing material only arranged is being arranged between positive striking surface and the auxiliary striking surface, and it makes sportsman's instep and the bending between the tiptoe convenient.

The reason that these football boot can improve shooting average is described in detail in detail below:

With reference to Fig. 3,4,10, in its degree of accuracy, there are two errors when wearing existing football boot shooting:

1, the error that produces because of the swinging kick direction because actual swinging kick direction departs from desirable swinging kick direction N2, makes the error of the traffic direction generation ± α of ball;

2, the error that produces because of the instep shape, because of the irregular curved surface of instep, striking point on the ball can not match with placement point, because of the effect of constraint reaction direction N5, makes the error of the traffic direction generation ± β of ball.

Last two errors, the swinging kick error produces before batting, and the error that produces because of the instep shape should superpose thereon, so its overall error is an alpha+beta, by landing error M1=± tg (alpha+beta) L of the ball that kinematic error produced of ball, L represents shooting range in the formula so.

Concerning the football player, generally very little through training back swing leg error, promptly the α value is very little, control the error that causes because of the instep shape and then be difficult to, so the β value is often much bigger than the α value.When β＞α, tg (alpha+beta)＞tg2 α＞2tg α this shows that the error M1 of placement is far longer than 2tg α L when wearing existing football boot shooting.

With reference to Fig. 7,8,9,11, wear these football boot, when athletic swinging kick in the right direction when errorless, no matter ball is which point ejaculation from positive striking surface, all as penetrating from ideal point, this face imposes on the active force of ball--and the direction of constraint reaction all is perpendicular to this plane, all is identical, and the suffered constraint reaction direction of ball is consistent with the desirable shot direction that the sportsman is aimed at.And when the error of athletic swinging kick direction existence ± α, the error that the traffic direction of the ball of shooting this moment so produces has only ± α.The landing error M2=of ball ± tg α L gets its absolute value, M2=tg α L.

By as seen above-mentioned, wear the shooting of the utility model football boot, than wearing existing football boot, the shooting degree of accuracy and hit rate will improve more than 1 times.In addition because the effect of constraint reaction direction, effective strength of batting is strengthened, the speed of service of ball is accelerated: when curving the ball with positive striking surface, because of efficient beating area of the bat big, significantly extend the time of contact of ball and striking surface, and the banana kick revolving force of ejaculation is significantly strengthened, and the trajectory curvature of ball is bigger, such ball goalkeeper is difficult to pounce on and catches, and the chance that scores the goal is improved greatly.

The shoelace buckle of these football boot is positioned on the heel of a shoe place, and shoestring ties up to heel of a shoe, and this structure has also avoided shoestring effectively on instep, the ball of shooting when shoelace buckle and shoestring penetrate, issuable unforeseen error.

Utilize these football boot, can finish any technical movements easily and effectively, as straight shot, swerving shot, shoot in the way of overhead hook, place kick, propel, shovel penetrate, pass, receive, trapping, dribbling, volley shot etc., the degree of accuracy of each technical movements be can improve greatly, the shooting average and the rate that scores the goal effectively improved.
