Description
Technical field
The present invention relates to a kind of energy rebound sport shoes.
Background technology
In recent years; Both at home and abroad obtained scientific and technological progress highly visible aspect the motion safeguard function of footwear improving; Manyly be widely used among the athletic shoe designs about shock-absorbing damping and comfortable technology of fitting; The sports goods company that comprises Adidas, Nike has all developed and has a kind ofly produced the shoe-pad of kinetic energy when absorbing the heel colliding surface, realizes the damping balance thereby can absorb the impact kinetic energy that produces in each gait cycle.The research of sport biomechanics shows; The cushioning effect of overemphasizing shoe-pad can greatly reduce wearer's running efficient; The effect of arch of foot is equivalent to spring, and this position can be converted into impact kinetic energy deformation potential and efficiently discharges with assisted walk during lifting once more at foot, and the sport footwear of various functional insoles can absorb the impact kinetic energy up to 67%; But because shoe-pad does not have the similar functions of spring, these energy are wasted fully.So, not only will consider to absorb impact kinetic energy to the design of the function of article of footwear, also to consider how to utilize the energy that is absorbed, and in gait cycle the suitable time discharge it, thereby reach the resilience power-assisted, strengthen the requirement of comfortableness.
According to the achievement in research of biomethanics, the energy rebound of sport footwear need be considered three factors: time effect, frequency effect and position effect; Time effect is meant that the release of energy must be in correspondence constantly, and for example in the running process, athletic per step supporting time hypothesis is about 200ms; In 0～100ms, pedal motion before athletic pin is done so, this moment, the shoes compressive deformation stored elastic energy; And at 100～200ms in the time period, the sportsman is pedaled after lower margin, and shoes are if discharge the kinetic energy that elastic energy then helps to increase human body at this moment; Or people's physical efficiency is utilized the elastic energy of shoes; If shoes have stored elastic energy in 0～50ms, and in 50～100ms, have just discharged elastic energy, this elastic energy is the increase that is helpless to body kinetic energy so; Frequency effect is meant the necessary respective frequencies of the release of energy, and for example, on the marathon project, the supporting time of human body is at 250ms; Then answer the storage elasticity ability, and in back 125ms section, shoes should discharge elastic energy at preceding 125ms section shoes; One-period comprises 250ms or 4Hz, and for dash, the supporting time of human body is about 100ms; Then preceding 50ms time period shoes should storage elasticity can, and the 50ms shoes release energy in the back, frequency is 10Hz; Position effect is meant that the release of energy must be on corresponding location point, to have stored energy during the shoes pressurized; Pressure spot is on the heel of footwear, and after when pedaling, the touchdown point of pin is at the forefoot of pin; If the release position of shoes elastic energy is on heel; Then this energy to forefoot as the motion of the human body of fulcrum less than helping, so the design of shoes preferably can be in the heel storage power, and can release energy at the tiptoe position.
Utilization sport biomechanics basic theories and method, to the energy rebound effect of sport footwear, from energy source, recurrence approach and return the position and many aspects such as bottom material structure carried out application study.According to U.S. Patent search; Publication number is that the patent of US4627621 discloses a kind of correction shoe-pad of being made up of the multilayer graphite fibre with certain rigidity; Insole shape is the strip of a little arch in centre and directly places top, the big end; But we know that shoe-pad and the middle end absorb nearly 67% impact kinetic energy, and this just means that a lot of energy just had been absorbed before failing to arrive the liner of this particular design, and the energy-absorbing resilience effect of liner is difficult to performance.Also have; U.S. Patent Publication is that US4476964 discloses the two lining of a kind of what is called elastic buffering pad, and one of them is placed on heel area, and cup-shaped design makes it form good parcel and balance to calcaneum; When the heel colliding surface, accomplish of the conversion of bump kinetic energy to deformation potential through strain; Along with the continuity of gait cycle, active force reduces gradually between heel and the cushion pad, and cushion pad can recover original form as spring; Thereby with potential energy converting and energy is kinetic energy, realizes the driving power-assisted that heel makes progress; Another cushion pad is placed on the forefoot position, has the similar function of heel cushion pad; But the US4476964 invention can not realize the conduction of energy, and promptly heel portion position, back energy stored can only convert the kinetic energy that metapedes is followed to; The energy of forefoot can only convert the kinetic energy in sole zone to; And in fact we are that rear heel lands mostly in normal gait, and forefoot is liftoff, and main forward forward thrust of the sole of foot promotes to advance when liftoff; Be stored in the rear heel footwear elastic potential energy at the end and can only when heel is liftoff, return part energy; And the forefoot that when liftoff, plays the effect mainly had an effect often can not get the energy returned, if can be restored to forefoot to the energy of rear heel storage, the energy return rate can be greatly improved so.
