Description

Technical Field

[0001] The utility model belongs to the technical field of sole preparation, and in particular relates to a carbon fiber plate for soles, soles and shoes. Background Art

[0002] As people pay more and more attention to health, the number of people participating in sports such as running has increased exponentially. People's demand and requirements for sports equipment are gradually increasing. People pay more attention to sports safety and pay more attention to the addition of sports equipment to sports performance. Ordinary sports equipment can no longer meet people's sports needs. Sports equipment is becoming more and more specialized, functional and segmented.

[0003] There are basically two types of professional running shoes on the market: one focuses on straight-line long-distance running, such as marathons; the other is short-distance racing shoes. These two types of shoes have different design concepts and focuses, so they cannot be taken into account. Shoes suitable for long-distance running increase the overall thickness of the sole to increase the buffer distance to obtain more elasticity and increase comfort. However, this type of shoe is not suitable for field sports. Because the sole is thickened, the stability in the corners will be greatly reduced, and sprains and other safety hazards are prone to occur, while the efficiency is reduced. Racing running shoes are professionally designed only for the forefoot traction point, which has great advantages in short-distance running, but is not helpful for middle and long-distance running, and factors such as the angle and hardness of the sole will affect the results. Utility Model Content

[0004] In order to solve the above existing problems, we have developed a pair of sports shoes that use carbon plates to assist support and provide increased elasticity. The special structure meets the needs of both long-distance and short-distance running. While increasing stability and safety, it can also greatly improve exercise efficiency, reduce unnecessary physical loss, and thus improve sports performance. The technical breakthroughs are as follows:

[0005] A carbon fiber plate for a shoe sole comprises a forefoot portion, an arch portion, a heel portion and a trailing edge; the forefoot portion is curved downward in an arc shape, the heel portion is raised in an arc shape upward and reaches a highest point near the root bone; the arch portion is arranged between the forefoot portion and the heel portion, and the trailing edge is arranged at the end of the heel portion and is curved downward.

[0006] As an improvement, the arc height of the heel portion is 5-30 mm.

[0007] As an improvement, the arch portion smoothly transitions between the forefoot portion and the heel portion with a preset curvature.

[0008] The utility model also discloses a sole, comprising a wear-resistant layer, a first shock-absorbing layer, a second shock-absorbing layer and a carbon fiber plate, wherein the first shock-absorbing layer and the second shock-absorbing layer respectively wrap the carbon fiber plate from the bottom and the top, and the wear-resistant layer is arranged at the bottom of the first shock-absorbing layer;

[0009] The sole is provided with a support block at the rear of the trailing edge of the carbon fiber plate, the top and bottom of the support block are fixedly connected to the second shock-absorbing layer and the first shock-absorbing layer respectively, the support block is provided with a groove on one side close to the carbon fiber plate, and the trailing edge of the carbon fiber plate is arranged in the groove.

[0010] As an improvement, the front portion of the support block adopts a straight structure, the rear portion is an arc-shaped structure, and the shape of the groove matches the trailing edge.

[0011] As an improvement, the sole is provided with a hollow portion at the first shock-absorbing layer, and the hollow portion is arranged at a position corresponding to the arch of the carbon fiber plate.

[0012] The advantages of the utility model are:

[0013] 1. The carbon fiber plate in the utility model adopts a prefabricated one-piece carbon plate, which is set in the midsole of the shoe to effectively increase the stability of the shoe. During long-distance running, many people use the running method of landing on the heel, that is, the heel lands first, and then rolls forward to the forefoot in sequence. The rear root of the utility model adopts an upward arc-shaped bulge design, and reaches the highest point near the root bone, which can provide sufficient cushioning for the rear foot position, and can provide greater and faster rebound force during the resetting of the carbon plate. The utility model generates sufficient elastic potential energy through the deformation of the rear root, and then releases the potential energy during the rebound process to convert it into additional power for the foot. The forefoot of the utility model adopts a downward arc, and the focus can be transferred to the forefoot. Because of the curvature of the sole, an effect similar to wheel rolling will be produced, which minimizes the power loss caused by the deformation of the sole.

[0014] The carbon plate of the utility model has better rebound force and rebound effect than the traditional carbon plate. At the same time, the product has good supporting performance and stability. It can improve the efficiency of exercise and improve the athletic performance of the runner while ensuring the safety of running.

[0015] 2. The utility model is provided with a support block at the midsole position of the sole. Since the heel carbon plate adopts an arc structure that bulges upward, a large degree of deformation will occur when the heel contacts the ground. During the deformation process, the main force point is concentrated at the trailing edge of the carbon plate. In the case of long-term use, the midsole material near the trailing edge will be heavily burdened, resulting in fatigue damage, permanent deformation, and even direct tearing. The design of the support block and the groove first leaves space for the deformation of the carbon plate at the trailing edge of the carbon plate. The carbon plate can deform inside the groove without causing a large deformation effect on the surrounding midsole material, thereby avoiding the problem of tearing of the midsole material due to deformation; secondly, the support block can effectively increase the contact area between the trailing edge of the carbon plate and the midsole material, thereby dispersing the high stress generated at the trailing edge and avoiding the problem of stress concentration in the midsole material near the trailing edge. This structure can disperse the stress to the heel position of the sole, avoid the generation of large local stress, and increase the service life of the midsole material.

[0016] 3. The utility model designs the forefoot of the carbon plate into an arc shape, and thins the forefoot of the sole material. In this way, the carbon plate will deform with the pedaling action during sprinting, achieving a spring-assisted effect, thereby improving the efficiency and performance of the sport.

[0017] 4. The utility model can minimize the power loss during exercise, greatly improve the efficiency of exercise, and thus achieve better results. At the same time, because of the implantation of the carbon plate, the overall strength of the shoe is increased, and the overall stability of the shoe is improved, thereby avoiding sports injuries caused by shoe deformation or insufficient support.
