Abstract

The invention discloses a rigid component for soles, which is a rigid plate material for covering soles, and is formed by longitudinally connecting a half sole section, an arch section and a heel section, wherein the half sole section extends from a corresponding toe to the front end of the arch section in a curve, the arch section extends from the corresponding sole arch to the front end of the heel section in a curve opposite to the bending direction of the half sole section, and the heel section extends from the corresponding heel to the rear end of the arch section, and the rigid component is characterized in that the bending degree of the half sole section to the arch section is 20-30 degrees, and under the bending degree, when the rigid component is placed in the sole and is deformed by a user, the rigid component can apply upward and forward elastic force to the user, can apply larger force at the initial stage of deformation, keeps the applied force stable, and helps the user to apply force in a more labor-saving and more effective mode, so that the user can obtain higher speed.

Description

Rigid part for sole, sole and shoe Technical Field The invention relates to the technical field of footwear products, in particular to a rigid part for a sole, the sole and shoes. Background The steel frame snowmobile is a motion on ice with the highest speed per hour of 140 km/h, the athletes wait in line at the starting point in order before starting, and after the referee presents a starting signal lamp, the athletes rapidly push the steel frame snowmobile to run forward, and the distance is 50 meters to push the snowmobile to do acceleration motion. The departure process from start to boarding of the snowmobile must be completed within 30 seconds. In the whole competition, all athletes can only rely on self force to complete the competition, and foreign objects and external force cannot be used. The steel frame snowmobile provides that the athlete can only go on in prone position in the competition process, the power comes from the gravity of the athlete and the thrust of the athlete to the snowmobile, and the direction control is realized by the movement of the body of the athlete. Therefore, to obtain a higher initial speed, the athlete is required to run faster during the running stage, and the sole of the existing shoes for steel frame snowmobile is generally provided with steel nails to provide gripping force, but the ground is softer during running, so that better support cannot be provided for the athlete, and the athlete cannot apply force better. Disclosure of Invention The present invention has been made to overcome the above-mentioned drawbacks or problems occurring in the prior art, and an object of the present invention is to provide a rigid part for a shoe sole, a shoe sole and a shoe, which limit the degree of curvature of the rigid part, at which the rigid part, when placed in the shoe sole and deformed by a user riding on the ground, exerts an upward and forward elastic force on the user, and exerts a large force at the beginning of the deformation, and keeps the force stable, helping the user to exert a force in a more labor-saving and more efficient manner, thereby enabling the user to obtain a faster speed. . In order to achieve the above purpose, the present invention adopts the following technical scheme: A rigid element for soles, which is a rigid plate material for covering soles, consisting of a half sole section, an arch section and a heel section which are longitudinally connected, wherein the half sole section extends from a curve corresponding to toes to the front end of the arch section, the arch section extends from a curve corresponding to the arch of the sole to the front end of the heel section in a bending direction opposite to that of the half sole section, and the heel section extends from the corresponding heel to the rear end of the arch section, and the rigid plate material is characterized in that the bending degree from the half sole section to the arch section is 20-30 degrees. Further, the curvature of the forefoot section to the arch section is 22 ° to 26 °. Further, the curvature of the forefoot section to the arch section is 25 °. Further, a tangent line formed by taking the maximum curvature of the arch section as a starting point and tangent to the half sole section is a first tangent line, a tangent line of the half sole section corresponding to a boundary point of the plantar metatarsal and the toes is a second tangent line, and an included angle between the first tangent line and the second tangent line is the curvature. Further, the rigid member is made of a carbon fiber material. In addition, the invention also provides a sole comprising a midsole, wherein the midsole is internally provided with the rigid component. Further, the midsole is formed by combining an upper sole, a lower sole and the rigid component between the upper sole and the lower sole. In addition, the invention also provides a shoe comprising a sole as claimed in any one of the above. As can be seen from the above description of the present invention, the present invention has the following advantages over the prior art: The rigid part for the sole provided by the invention limits the bending degree from the half sole section to the arch section of the rigid part to 20-30 degrees, and the preferable angle range is 22-26 degrees, especially 25 degrees, under the bending degree, when the rigid part is placed in the sole and is deformed by a user stepping on the ground, the rigid part can apply upward and forward elastic force to the user, can apply larger force at the initial stage of deformation and keep the force applied stably, and helps the user to apply force in a more labor-saving and more effective mode, so that the user can obtain faster speed. While the bending of the rigid element cannot be infinitely increased for the teaching of the prior art, the increase of the bending in general can effectively increase the elastic force of the rigid element when it is deformed, thus he
