Description

The high resiliency sole

Technical field

The present invention relates to a kind of high resiliency sole.

Background technology

The people is when walking, and the exchange process of step is known from experience the generation vibrations to the people, and body shake relates to the positions such as joint, brain and heart at each position, if shaking force is bigger, these positions is very easily damaged.Because when human body was walked, the focus that produces vibrations came from sole, so wanting to alleviate or avoiding body shake power, unique solutions is the elasticity that increases sole.For this reason, in the prior art, adopt rubber or ethylene-vinyl acetate copolymer usually, to improve the pliability and the impact resistance of sole as the raw material of making sole.Yet sole is again directly to contact with ground and the parts of grantee's body weight power, under normal conditions, the pliability of sole or elasticity and impact resistance are conflicting, and promptly flexility is good more, and its impact resistance is just poor more, and the good more sole of flexility, it is comfortable more that the people feels; Another problem is, the people is when wearing footwear and walk, to the active force that sole applied mainly is to concentrate on the heel position, so, the mode that prior art adopts extra depth shoe to follow usually improves its pliability, but the increase of heel thickness also can directly cause the increase of quality, simultaneously also increase cost of manufacture, and also can reduce its impact resistance to a certain extent.

The name of No. 2762593 Granted publications of Chinese patent is called " health shoes " and provides a solution.This health shoes is provided with a cavity at the heel position, in this cavity, be provided with spring and be installed in the shock-absorbing boosting device that constitutes by plate of this spring upper surface, wherein spring adopts circle, arc, triangle, square, polygonal one or more combination, from its disclosed content, circle, arc, triangle, square, polygon spring refer to inferior thick cylindrical body, and arc refers to the spring leaf of arc.Though the spring of installing at the heel position can play damping and power-assisted effect in its elastic limit, but, because the quality difference of human body, the elastic limit of damping spring can not be applicable to the people of all body weight again, when people's body weight during greater than its elastic limit, spring is followed the string, simultaneously also can pressuring spring when walking, make it send the unpleasant to hear sound; And when people's body weight during less than its elastic limit, spring does not have the effect of damping and power-assisted to human body; In addition, because circle, triangle, bottom square, the polygon spring that this health shoes proposed are not provided with the dividing potential drop limiting component that can play reinforcement effect, the contact area of spring and sole is less, the pressure that causes unit are to be born is bigger, and sole is worn by its pressure easily, even if adopt up-small and down-big turriform spring, though can avoid spring to send the unpleasant to hear sound, but can not increase the spring cross-sectional area, sole is pressed by spring easily too and worn, thereby the service life of reducing sole.

Summary of the invention

The purpose of this invention is to provide a kind of high resiliency sole that utilizes the mode that resilient projection directly is set to solve problems such as low and elasticity deficiency in sole service life on pad behind the sole.

The periphery of the back pad of high resiliency sole proposed by the invention is provided with the convex edge of extending upward, and the shank position in the convex edge is provided with the resilient projection of extending upward.The back pad adopts rubber or ethylene-vinyl acetate copolymer to make, and the back pad is become by mould, and convex edge wherein and resilient projection are to be integral with the back pulvilliform, promptly adopt same mould to make.

Described foremast is provided with the elasticity raised line that extends upward.Described elasticity raised line is the bar shape of the hollow bending of upper surface sealing.Described elasticity raised line is provided with the 2-8 bar.

Described resilient projection is hollow cylindrical body or the prismatic body of hollow or the spherical crown or the segment of upper surface sealing.Described resilient projection is provided with 1-6.

The upper surface of described back pad also is equipped with identical with it or the akin pressure-bearing plate of shape, and this pressure-bearing plate is provided with through hole or groove.Described pressure-bearing plate comprises first rigid plate and overlapping second rigid plate that is placed on the first rigid plate upper surface.

Magnetic patch is installed in the through hole of described pressure-containing member.

Resilient projection in the high resiliency sole proposed by the invention exceeds other position of back pad, because of its be with the back pad with material and for the rubber type of material of one constitutes, so resilient projection has quite desirable elasticity, and it fills up with the back and be integral, and is not fragile; Simultaneously, because of the pressure-bearing plate is provided with through hole or groove, when exchanging along with people's step, rising and falling of resilient projection can make the gas in the footwear discharge or be inhaled into through described through hole or groove in the pad of back, thereby gas and ambient atmos in the footwear are exchanged, to keep the footwear drying, avoid bacteria breed.
