Abstract
The invention discloses a spike body structure of a spiked running shoe, which comprises a threaded part, a front spike and a rear spike. The spike body structure is characterized in that a spike body adopts a conjoined fork-type design that the front spike and the rear spike share the same one spike base; the two spikes form an angle theta, the angle theta is an angle formed between a sole and a race track when an athlete completes soaring and starts to touch the ground, a forward declination angle which is 90 degrees minus theta is formed between the front spike and the sole, and a right angle is formed between the rear spike and the sole; and the length of the front spike is L and the length of the rear spike is Lcos(theta). When the spike body is used on a running shoe, since the front spike and the race track form a right angle when the athlete touches the ground, the energy loss caused when the spikes are inserted into the race track is reduced and the braking performance is guaranteed; since the time for the rear spike to touch the ground is slightly later than that of the front spike, the impact load which is transferred to a foot sole and a lower limb is reduced and the buffering performance is improved; since the rear spike and the ground form a forward acute angle when the athlete leaves the ground, the pulling-out of the rear spikes is facilitated; since the design that the two spikes are distributed in a splayed shape is adopted, the stability of the spiked running shoe is increased; and the spike body structure of the spiked running shoe effectively improves the buffering performance of the spiked running shoe and guarantees the braking performance and the stability of the spiked running shoe at the same time.
Description
Technical field
The present invention relates to the shoe tack nail body structure of the race spikes of use in a kind of shoe tack the nail body structure, particularly dash campaign.
Background technology
The main effect of running spikes in the dash campaign is to pedal after helping forefoot to exert oneself fast, and accumulating more by the reaction force of pedaling ground, great improves explosive force and speed.In this process, when pin landed, shoe tack can be through being out of shape the impact of facing pin, storage part elastic potential energy with absorbing; When less touch with the ground, footwear give foot to accelerate velocity the energy feedback that is absorbed.Shoe tack is the intermediate between ground and the human body, pedals 5-10 that when ground ground is about sportsman self body weight in the face of the reaction force of pin doubly.Pedaling soil fertility like certain sportsman's maximum is 3000N, and sole forefoot area is 100cm
2, then its average shock loading is 30N/cm
2, and in fact shoe tack and contact area of ground are far smaller than the forefoot area, then shock loading will increase greatly.If there is not good shock mitigation system to alleviate impact, motion is prone to cause fatigue after finishing.Therefore shoe tack also need absorb the runway impact in lifter motion usefulness.The structure of shoe tack nail body will to buffering and after pedal the generation material impact.Therefore, the design demand of shoe tack nail body takes into full account its rigidity and toughness under impact loading.Nail body rigidity is little, and shock-absorbing capacity is good, but distortion recovers slow, pedals after being unfavorable for.Shoe tack rigidity is big, is unfavorable for buffering again.
Biomechanics experiment chamber researcher finds woodpecker cranial anatomy structure and motion analysis; Woodpecker beak portion structure is different with other birds; Its beak up and down is not isometric; And pecking wooden end upper and lower beak of back moment can open rapidly, and this beak cage structure and motion mode help absorbing shock loading, avoid damage with the protection brain.The present invention is used for the beak portion structure of woodpecker and motion feature to run and improves resiliency when the spikes shoes nailed structure realizes running the spikes braking with stability.
Summary of the invention
The object of the invention is exactly to the deficiency of existing nail body aspect damping, utilizes the principle of woodpecker head impact resistance damage, proposes a kind of shoe tack nail body structure, improves the shock-absorbing capacity that runs spikes.
For solving above technical problem, the present invention realizes through following technical scheme: a kind of shoe tack nail body structure that is mainly used in the race spikes of dash campaign, this shoe tack nail body structure is formed a whole by threaded portion, preceding tack claw, back tack claw three parts.
Said shoe tack is characterized as: adopt the dichotomous design of disjunctor of the shared same nail seat of forward and backward two tack claws.Angle between two tack claws is θ (when θ finishes to begin to land mutually when soaring for the sportsman, sole and runway face angulation), between wherein preceding tack claw and the sole 90 a °-θ in drift angle is forward arranged, and back tack claw and sole meet at right angles.Preceding tack claw length is L (L is for running spikes international standard specific length scope), and back tack claw length is Lcos θ.
Through such scheme, when the present invention was used for dash race spikes, when landing, preceding tack claw and runway face met at right angles; Can make tack claw insert runway quickly and effectively, reduce energy loss, for after pedal the stage and accumulated energy, be converted into strong onward impulse; Guaranteed braking, and the rear solid end touchdown time slightly is later than fore paw, has shared the part shock loading; Weakened the transmission of shock loading, thereby reached the bumper and absorbing shock function, protection sporter's both feet to sole and lower limb; When liftoff, rear solid end becomes the acute angle of a forward direction just with ground, be beneficial to rapidly and extract.In addition, a nail body of the present invention comprises that the design that two tack claw Eight characters launch has increased the stability of running spikes.
Description of drawings
Fig. 1 is a sketch map of the present invention;
Fig. 2 is for being application sketch map of the present invention;
Among the figure: 1 threaded portion; 2 back tack claws; Tack claw before 3; 4 footwear bodies; 5 nail bodies.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
As shown in Figure 1, the present invention is made up of three parts: threaded portion, preceding tack claw, back tack claw.It is characterized in that this shoe tack is by the dichotomous nail bodies with two shared nail seats of tack claw shown in Figure 1, by afterwards tack claw 2 and preceding tack claw 3 are formed.Angle between two tack claws is θ (when θ finishes to begin to land mutually when soaring for the sportsman, sole and runway face angulation), and the 90 °-θ in drift angle of a forward direction is arranged between wherein preceding tack claw and the sole, and back tack claw and sole meet at right angles.Preceding nail length is L, and back tack claw length is Lcos θ.The present invention can use in the running shoes shoe tack manufacture craft manufacturing materials commonly used to process.
In the shoe tack nail body structure that the present invention relates to; Preceding tack claw becomes the design of 90 °-θ forward direction drift angle to make when landing with sole; Before tack claw just and the runway face meet at right angles, can make tack claw insert runway quickly and effectively, reduced energy loss; For after pedal the stage and accumulated energy and be converted into strong onward impulse, guaranteed braking; Then the tack claw touchdown time slightly is later than preceding nail, shares the part shock loading and realizes the bumper and absorbing shock function; Because back tack claw and sole meet at right angles, and become a forward direction acute angle with ground just when liftoff, are beneficial to rapidly and extract.Simultaneously, the design that becomes the θ angle Eight characters to launch between two tack claws has increased the stability of running spikes.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structural change of under enlightenment of the present invention, making, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
