Running shoe capable of reducing knee injury probability during running

Technical Field

The utility model relates to the technical field of sports shoe manufacturing, in particular to a running shoe capable of reducing the probability of knee injury during running.

Background

It is known that when running, one foot is generally on the ground, but the weight of the whole body is concentrated. The knee is used as a main structure for resisting impact and buffering when a human body runs and bears most of stress and buffering. In the running process, the rear foot of the front foot is firstly contacted with the ground, the front sole part is also contacted with the ground along with the forward movement of the gravity center of a human body, and the front sole part of the rear foot is separated from the ground, and two feet are contacted with the ground alternately and circularly to realize forward running. In the running exercise, the wrong running method can generate wrong foot falling points at the heels, and the resistance cannot be smoothly transited when the heels land, so that the impact of the knees cannot be reduced, and the knee injury probability is increased in the running process.

Non-professional running people (namely ordinary people) run by adopting the wrong running method without receiving professional training, so that the wrong foot drop point cannot be overcome, and the knee injury probability is high. However, the heel side walls of the existing sports shoes or running shoes are designed in a cliff type, and the function of changing the wrong foot drop point cannot be achieved. The prior running shoes have the following three defects during daily running exercise:

firstly, the injury of the knee caused by incorrect running posture cannot be reduced, and the probability of the injury of the knee cannot be reduced (namely, in the running process, the foot falling point of the front foot is still positioned at the heel and is contacted with the ground, and in the instant of the contact with the ground, the large impact is generated, the ground reaction force is conducted on the body through the knee, so that the impact of the knee cannot be reduced). Not only the probability of knee injury is increased, but also bones at the knee are seriously abraded, and the serious injury is brought to a user.

Secondly, the heel of the existing running shoes has no auxiliary structure, so that resistance cannot be smoothly transited, resistance is generated to running, and running speed is influenced.

Thirdly, there is not any bounce-back structure in the running shoes, can't play and assist the running, reduce the tired effect of foot.

Accordingly, the present inventors have made extensive studies on the conventional running shoes, and have made the present invention.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.

As shown in fig. 1-5, the running shoe for reducing the probability of knee injury during running of the present invention includes a sole body 1, and an elastic reinforcing plate 6 is disposed in the sole body 1 and extends to the heel corresponding to the sole of a human body, and is used for assisting running and reinforcing the sole body 1 from the sole to the heel, and specifically, the elastic reinforcing plate 6 is an existing carbon plate (i.e., an existing carbon fiber plate).

The rear end of the sole body 1 corresponds to the back upper of the running shoe and is integrally formed with a reinforcing block 5, the bottom surface of the reinforcing block 5 extends from front to back in an inclined mode to form a heel arc surface enabling a running center of a human body to be front and a heel foothold to be located behind the running center of the human body, the bottom surface of the sole body 1 is integrally formed with an extending section which extends upwards in an inclined mode to the rear end of the reinforcing block 5 and is connected with the reinforcing block, the extending section is located on the central line of the sole body 1, and the portions, located on the left side and the right side of the extending section, of the bottom surface of the reinforcing block 5 are arranged in an inclined mode. By adopting the structure, the reinforcing block 5 is used for reinforcing the part, corresponding to the inner side and the outer side of the foot of a human body, of the sole body 1 to the heel of the human body, so that the foot can be prevented from being sprained during running. During running, the whole heel can be used for landing without excessively depending on buffering when the foot touches the ground, and the included angle between the sole and the ground when the heel touches the ground is controlled to be as small as possible. Through heel arcwall face and extension section, make human running center leading, heel foothold is in human running center rear, sole and ground contained angle when can minimize the heel to touch to earth, make human heel contact ground focus antedisplacement, the heel contact ground foothold of sole body 1 moves backward, human focus is in with shoes heel contact ground the place ahead (produce reaction force and human focus not be in same straight line when the heel of sole body 1 contacts ground promptly), it is incorrect because the shoes structure is not enough or the appearance of running when having solved to run, because there is the huge impact in the twinkling of an eye when making heel direct contact ground, can bring the problem of serious damage to the runner. As soon as the heel touches the ground, the heel is converted into the sole falling to the ground as soon as possible, and the impulse is dispersed to the whole sole. The probability of mistaken falling of the feet is reduced, the resistance of the forefeet when the forefeet land is reduced, the stable transition is realized, the effect of the reaction force generated on the knees when the ground is effectively reduced, the reaction force generated when the knees are contacted with the ground is smaller, and the probability of injury of the knees is effectively reduced. The problem of current ordinary running shoes can't be not enough through self structure, appear wrong placement in the running and lead to the knee damage is overcome. In other words, the bottom surface of the reinforcing block 5 extends from front to back in an inclined manner, so that an extending section which enables the running center of the human body to be front and the heel falling point to be positioned behind the running center of the human body and the heel of the sole body 1 are integrally formed, and the extending section is connected with the reinforcing block 5 in an inclined manner, so that the probability of wrong falling points is controlled, and stress is effectively distributed and transferred (for example, a pen rolls forwards along with the ground after falling, the impact force is reduced, the landing height is small, and the impact force is weaker), and the probability of knee injury is reduced. Say again that some specialty points, the law of conservation of energy, the energy can not disappear by the sky, but can shift, 1 foot of sole body is fallen the point and is contacted the transition through the heel arcwall face and the extension segment of strengthening the strake, realizes shifting the energy through the rolling friction mode, changes the direction of energy concentration effect, the heel arcwall face and the extension segment dispersion of strengthening the strake on the sole body 1 and absorbed the kinetic energy that a part of foot fell to the ground, the knee is whether just can bear a bit less, knee injury probability when reducing and run.
