Description

Technical Field

[0001] The present invention relates to the technical field of sports shoes, and particularly to an energy-recycling sports shoe. Background Art

[0002] The sole of a sports shoe is different from that of ordinary leather shoes or rubber shoes. Generally, it is soft and elastic, which can play a certain buffering role. It can enhance elasticity during exercise, and some can also prevent ankle injuries. Therefore, when doing sports, most people wear sports shoes, especially for high-intensity physical activities.

[0003] When wearing sports shoes for exercise, the bending degree in the forefoot area is the largest. The general path of energy conversion in sports shoes during exercise is that when stepping on the ground, it drives the sole to bend, and when lifting the leg, the sports shoes return to their original shape. This part of the energy is used to assist the movement, thereby achieving energy recycling. Generally speaking, it is the storage and release of elastic potential energy of the sports shoe sole. However, the above energy conversion process will inevitably generate additional heat energy, increasing the heat of the sole, making it uncomfortable to wear or causing sweating on the feet. Summary of the Invention

[0004] To overcome the technical defects existing in the prior art, the present invention provides an energy-recycling sports shoe, which enhances the resilience performance of the sports shoe.

[0005] The technical solution adopted by the present invention is as follows:

[0006] The energy-recycling sports shoe includes an outer shoe body, an inner shoe body, and an energy-recycling system. The outer shoe body is provided with an upper arc surface inside. The bottom of the inner shoe body has a lower arc surface that is mutually adapted to the upper arc surface. The upper arc surface and the lower arc surface slide relative to each other, and the geometric centerlines of the upper arc surface and the lower arc surface coincide. The energy-recycling system passes through the lower arc surface and is installed on the upper arc surface. The energy-recycling system is elastic and is detachably installed at the bottom of the outer shoe body.

[0007] Preferably, the bottom of the outer shoe body has anti-slip patterns, and the anti-slip patterns form depressions at the forefoot position. The energy-recycling system penetrates through the bottom of the outer shoe body at the depression position.

[0008] Preferably, the inner shoe body includes a fitting inner liner and an installation base. The fitting inner liner is used to wrap the foot, and the installation base is located at the sole position of the fitting inner liner.

[0009] Preferably, the installation base is a rubber sheet pasted at the sole position of the fitting inner liner.

[0010] Preferably, the energy recovery system includes a rubber band, a plurality of main fixing devices, and a plurality of stud fixing devices. The middle part of the rubber band is located outside the bottom of the outer shoe body. The two ends of the rubber band sequentially pass through the bottom, the lower arc surface, and the upper arc surface of the outer shoe body. The two ends of the rubber band are respectively installed on the upper arc surface through the main fixing devices. The stud fixing device passes through the rubber band and then fixes the rubber band to the bottom of the outer shoe body.

[0011] Preferably, the stud fixing device is made of plastic, and the upper part of the stud fixing device is provided with thread patterns adapted to the outer shoe body.

[0012] Preferably, a transition piece is provided on the bottom of the outer shoe body close to the rubber band. The transition piece is made of plastic, and the stud fixing device is installed on the transition piece through a thread pair.

[0013] Preferably, an upper rotary contact plate is provided on the bottom of the inner shoe body. The upper rotary contact plate is made of plastic, and the upper rotary contact plate forms the upper arc surface.

[0014] Preferably, a lower rotary contact plate is provided inside the outer shoe body. The lower rotary contact plate is made of plastic, and the lower rotary contact plate forms the lower arc surface.

[0015] The beneficial effects of the present invention are as follows:

[0016] An upper arc surface is provided inside the outer shoe body, and the bottom of the inner shoe body has a lower arc surface that is mutually adapted to the upper arc surface. The upper arc surface and the lower arc surface slide relative to each other, and the geometric centerlines of the upper arc surface and the lower arc surface coincide. When moving, the upper arc surface and the lower arc surface slide relative to each other, thereby causing the outer shoe body and the inner shoe body to rotate relative to each other, providing a stroke for the energy recovery of the energy recovery system. The energy recovery system passes upward through the lower arc surface and is then installed on the upper arc surface. The energy recovery system has elasticity, and the energy recovery system is detachably installed on the bottom of the outer shoe body. When the energy recovery system is installed on and detached from the outer shoe body, it is divided into two working states.

[0017] The first working state is: when the energy recovery system is installed on the outer shoe body, wearing the sports shoes and exercising will cause the upper arc surface and the lower arc surface to slide relative to each other. However, due to the elasticity of the energy recovery system, there will be a resistance restraint from the elasticity of the energy recovery system for the mutual sliding of the upper arc surface and the lower arc surface in both directions. Also, since the energy recovery system passes through the lower arc surface and is installed on the upper arc surface, the length of the energy recovery system is elongated, greatly increasing the ability of the energy recovery system to store elastic potential energy. Since the energy recovery system passes through the lower arc surface, the radian is increased, causing heat to be generated on the lower side of the upper arc surface, reducing the heat generation inside the inner shoe body. On the other hand, the rebound performance of the sports shoes is enhanced, and the energy recovery ability of the sports shoes is enhanced.

[0018] The second working state is as follows: when the energy recovery system is not fixed to the outer shoe body, that is to say, when both ends of the energy recovery system are installed on the upper arc surface and the middle part of the energy recovery system is not fixed to the outer shoe body, when wearing, the energy recovery system wraps around the bottom of the outer shoe body. In this way, when moving, the upper arc surface and the lower arc surface slide relative to each other, causing the outer shoe body and the inner shoe body to rotate relative to each other. As a result, it will cause mutual friction between the energy recovery system and the outer shoe body. When moving, the heat is concentrated on the outside of the outer shoe body and dissipated, reducing the heat inside the inner shoe body and the inner side of the outer shoe body during movement, increasing the wearing comfort. In this working state, the rebound performance of this sports shoe is released, and more energy is consumed when walking, which is suitable for people who want to lose weight. Since the present invention has a normal walking state and an energy-consuming state, the user can switch at any time according to needs. Description of the Drawings

[0030] The present invention will be further described below with reference to the drawings:

[0031] As Figure 1 —Figure 7 As shown in the figure, this embodiment provides an energy - recycling sports shoe, which includes an outer shoe body 1, an inner shoe body 2, and an energy - recycling system 3. There is an upper arc surface inside the outer shoe body 1, and the bottom of the inner shoe body 2 has a lower arc surface that is mutually adapted to the upper arc surface. The upper arc surface and the lower arc surface slide relative to each other, and the geometric center lines of the upper arc surface and the lower arc surface coincide. During movement, the upper arc surface and the lower arc surface slide relative to each other, causing the outer shoe body 1 and the inner shoe body 2 to rotate relative to each other. The above - mentioned relative rotation provides a stroke for the energy recycling of the energy - recycling system 3. The energy - recycling system 3 passes upward through the lower arc surface and is then installed on the upper arc surface. The energy - recycling system 3 has elasticity and is detachably installed at the bottom of the outer shoe body 1. When the energy - recycling system 3 is installed and disassembled with the outer shoe body 1, it is divided into two working states.

[0032] The first working state is: when the energy - recycling system 3 is installed on the outer shoe body 1, wearing the sports shoes during exercise will cause the upper arc surface and the lower arc surface to slide relative to each other. However, due to the elasticity of the energy - recycling system 3, there will be a resistance restraint from the elasticity of the energy - recycling system 3 for the relative sliding of the upper arc surface and the lower arc surface in both directions. Also, because the energy - recycling system 3 passes through the lower arc surface and is installed on the upper arc surface, the length of the energy - recycling system 3 is stretched, increasing the ability of the energy - recycling system 3 to store elastic potential energy. Since the energy - recycling system 3 passes through the lower arc surface, the radian is increased, causing heat to be generated on the lower side of the upper arc surface, reducing the heat generation inside the inner shoe body 2. On the other hand, it strengthens the rebound performance of this sports shoe and enhances the energy - recycling ability of this sports shoe.

[0033] The second working state is: when the energy - recycling system 3 is not fixed to the outer shoe body 1, that is to say, when both ends of the energy - recycling system 3 are installed on the upper arc surface and the middle part of the energy - recycling system 3 is not fixed to the outer shoe body 1, during wearing, the energy - recycling system 3 wraps around the bottom of the outer shoe body 1. In this way, during movement, the upper arc surface and the lower arc surface slide relative to each other, causing the outer shoe body 1 and the inner shoe body 2 to rotate relative to each other. As a result, it will cause mutual friction between the energy - recycling system 3 and the outer shoe body 1. During movement, the heat is concentrated and dissipated on the outer side of the outer shoe body 1, reducing the heat inside the inner shoe body 2 and the inner side of the outer shoe body 1 during movement, increasing the wearing comfort. In this working state, the rebound performance of this sports shoe is released, and more energy is consumed during walking, which is suitable for people who want to lose weight. Because this invention has a normal walking state and an energy - consuming state, the user can switch at any time according to needs.

[0034] Specifically, the bottom of the outer shoe body 1 has anti-slip patterns. The anti-slip patterns form depressions at the forefoot position. The energy recovery system 3 penetrates through the bottom of the outer shoe body 1 at the depression positions. The above-mentioned depressions are used to provide installation positions for the installation of the energy recovery system 3, so that the energy recovery system 3 can be exposed at the bottom of the outer shoe body 1, facilitating heat dissipation. In other words, the anti-slip patterns play a supporting role for the outer shoe body 1 around the energy recovery system 3, and the anti-slip patterns around the energy recovery system 3 play a protective role for the energy recovery system 3, preventing the energy recovery system 3 from wearing and breaking too quickly.

[0035] Specifically, the inner shoe body 2 includes a fitting inner liner 21 and an installation base 22. The fitting inner liner 21 is made of knitted fabric and is used to wrap the feet. The fitting inner liner 21 is not limited to the shape shown in the attached drawings of the specification of this application, and is not even limited to the knitted fabric material. The function of the fitting inner liner 21 is to wrap the feet and transmit the walking and pedaling force of the feet to the energy recovery system 3. The installation base 22 is located at the sole position of the fitting inner liner 21. The installation base 22 is a rubber sheet pasted at the sole position of the fitting inner liner 21, which is convenient for the installation of the energy recovery system 3 and makes the installation of the energy recovery system 3 more stable.

[0036] Specifically, the energy recovery system 3 includes a rubber band 31, a plurality of main fixing devices 32 and a plurality of stud fixing devices 33. The middle part of the rubber band 31 is located outside the bottom of the outer shoe body 1. The two ends of the rubber band 31 sequentially pass through the bottom, the lower arc surface and the upper arc surface of the outer shoe body 1. The two ends of the rubber band 31 are respectively installed on the upper arc surface through the main fixing devices 32. The stud fixing devices 33 pass through the rubber band 31 and then fix the rubber band 31 to the bottom of the outer shoe body 1. The stud fixing devices 33 are used to fix the rubber band 31 on the one hand and to protect the rubber band 31 as studs on the other hand. On the other hand, the studs also serve as part of the anti-slip patterns.

[0037] Specifically, the stud fixing devices 33 are made of plastic. The upper part of the stud fixing devices 33 is provided with thread patterns adapted to the outer shoe body 1, which is convenient for the installation of the stud fixing devices 33. The main fixing devices 32 are also made of plastic, and the upper part of the main fixing devices 32 is provided with thread patterns adapted to the bottom of the inner shoe body 2.

[0038] Specifically, a transition piece 11 is provided on one side of the bottom of the outer shoe body 1 close to the rubber band 31. The transition piece 11 is made of plastic. The stud fixing devices 33 are installed on the transition piece 11 through a thread pair. The transition piece 11 is pasted on the bottom of the installation base 22. The transition piece 11 is used to install the stud fixing devices 33.

[0039] Specifically, an upper rotating contact plate 23 is provided at the bottom of the inner shoe body 2. The upper rotating contact plate 23 is made of plastic and forms an upper arc surface. The upper rotating contact plate 23 is pasted to the bottom of the mounting base 22. The upper rotating contact plate 23 is used to install and fix the main fixing device 32 through threaded patterns.

[0040] Specifically, a lower rotating contact plate 12 is provided inside the outer shoe body 1. The lower rotating contact plate 12 is made of plastic and forms a lower arc surface. The upper rotating contact plate 23 made of plastic and the lower rotating contact plate 12 have a low friction coefficient, which facilitates the outer shoe body 1 and the inner shoe body 2 to rotate relative to each other.

[0041] The main inventive point of the present invention is to utilize the elasticity of the rubber band 31 to recover energy during exercise, so that during exercise, the sports shoe repeatedly deforms to form a heat release position away from the position of the user's feet.

[0042] The rubber belt 31 is installed in such a way that the lower rotating contact plate 12 is pasted on the outer shoe body 1, and the two ends of the rubber belt 31 are respectively inserted into the preset channels at the bottom of the outer shoe body 1 until the two ends of the rubber belt 31 pass through the lower rotating contact plate 12 respectively, and then the ends of the rubber belt 31 are pried apart, and the main fixing device 32 is passed through the rubber belt 31 from the bottom to the top, and the upper rotating contact plate 23 is provided with a rotating hole for rotating the main fixing device 32. In order to facilitate the installation of the rubber belt 31 on the upper rotating contact plate 23, the main fixing device 32 has a step on the side close to the rubber belt 31 to press the rubber belt 31, and the main fixing device 32 has a cross groove, a straight groove or a hexagonal groove on the side close to the upper rotating contact plate 23. After the rubber belt 31 is installed on the upper rotating contact plate 23, the upper rotating contact plate 23 and the mounting base 22 are bonded to each other.
