Abstract

The utility model discloses one sliding steps shot putting footwear dorsad, comprise ball of foot, arch of the foot, heel three position footwear sole constructions.Global feature be front height, in flat, rear low, high, interior low before outer.Ball of foot sole upwarps thickening in the doubling of articulationes metatarsophalangeae line position, forms an inclined plane, and can improve sliding velocity in the sliding steps stage, in the end exert oneself the stage, area is removed on increase children education and ground, improves pressure---the time integral of right crus of diaphragm.Low in high before outside sole front end, be conducive to right pedal and stretch to have an effect and brake with left foot, raising sports achievement.Inclination angle before front tiptoe big toe male part site is conducive to maintaining balance.Thinning gradually on rear side of the heel heart, be conducive to sliding steps, be also conducive to alleviating shoes weight.Meanwhile, half sole reinforcement can adopt the technology such as hollow out, makes shoes more slim and graceful dexterous.

Description

Sliding steps shot putting footwear dorsad

Technical field

The utility model relates to a kind of shot putting footwear, belongs to slide-pace shot put training and competition special purpose shoes dorsad.

Background technology

Since entering 21 century, China's athletic equipment is tending towards improving with supporting, requires that sport footwear is more specialized, functionalization, researches and develops more and more refinement.For right hand throwing, want to improve shot release speed, one is improve sliding velocity and speed utilization ratio, and two is the braking actions strengthening left foot, give full play to right crus of diaphragm in the end firmly the stage pedal the effect of stretching, improve release speed.

Authorization Notice No. is that CN201005141Y description describes one " sport footwear sole for physical ability exercising ", these footwear adopt effort principle of going up a slope, adopt different colloidal materials to be bonded, upper strata is flexible glue layer, and lower floor is the gradient that the thickness of ebonite layer half sole and horizontal plane form 1 ° ~ 10 °.These footwear are applied in shot putting can unload power.In order to address this problem, the utility model patent combines distribution characteristics and the technical characterstic of slide-pace shot put foot force dorsad, designs the shape and structure of sole.

Summary of the invention

Part gravity and power of pedaling can be converted into power forward by the utility model, sliding velocity can not only be improved in the sliding steps stage, shorten transit time, but also the stage of can in the end exerting oneself increases the braking action of left foot, increase right crus of diaphragm and contact area of ground, improve pressure---the time integral of right crus of diaphragm.

Ball of foot sole upwarps thickening in toe sole of the foot joint line (AB) position, and upwarping angle (α) is 0 ° ~ 45 °, forms an inclined plane.

Metatarsophalangeal joint point (B) in sole articulationes metatarsophalangeae line (AB) and the 5th articulationes metatarsophalangeae point (A), 2 positions can move forward and backward according to personal touch, and moving range is 10% of whole shoe tree length; Horizontal line (CD) on big toe male part site is thinning gradually to shoes tip sole, with horizontal plane shape at a tilt angle (β ').

Because articulationes metatarsophalangeae line (AB) and a straight line (CD) by thumb male part site and perpendicular to the longitudinal axis have certain angle, so after articulationes metatarsophalangeae line upwarps thickening, make the outer front side of the sole of forefoot position high, inner side is low, forms the angle of inclination (β) of 0 ° ~ 30 °.

Sole is thinning gradually backward from rear crown of last heart position, and its thinning angle (γ) is 0 ° ~ 30 °.Whole sole present front height, in flat, rear low, outer front side is high, interior low, and the thickening position of sole all adopts round and smooth process.These footwear are conducive to improving sliding velocity, form good overstep apparatur.Meanwhile, be conducive to left foot braking, improve release speed and height of selling.

Detailed description of the invention

As shown in drawings, sole is with articulationes metatarsophalangeae line (AB) for starting point, and ball of foot sole (12) doubling upwarps thickening for structure of the present utility model.As shown in Figure 5, upwarp angle can control in 0 ° ~ 45 °.First toe sole of the foot artis (B) position can move up and down, and moving range can control in the shoe tree length of 10%.

Horizontal line (CD) on big toe male part site is thinning gradually to shoes tip, with horizontal plane ground shape at a tilt angle (β '), tiptoe sole upwarp angle, at the end of being conducive to final force, having an effect of right crus of diaphragm, is conducive to last cushioning balance simultaneously.

In the embodiment shown in fig. 1, articulationes metatarsophalangeae line (AB) and shoes left and right directions transversal line have certain angle, thus make toe bones interval point (C) sole thickness be greater than big toe interval point (D) sole thickness.As shown in Figure 4, shape at a tilt angle (β).Little toe section position thickness is greater than big toe part thickness, is conducive to the sliding steps stage to pedal interior turn of leg, ground, prepares for forming good overstep apparatur.In the final force stage, turn hip with being conducive to right pedal.

The heel heart position of sole (10) is thinning gradually backward.Because shot put shoes can be divided into trainer shoe and match footwear, trainer shoe half sole can adopt the real end, and shoes quality becomes large, can temper the strength of foot small muscle group like this.Match requires light and handy with footwear, in this case, fretwork technology can be adopted, hollow out is carried out at the half sole position of thickening, such as be embedded in cylindric hollow at the bottom of extra depth shoe, or the anti-skid design and drainage groove appropriateness that thicken position sole are deepened, so also can alleviate shoes quality, make shoes slimmer and more graceful.

Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employings are equal to or equivalent transformation is formed, all drops within the utility model scope required for protection.
