Description

Technical Field

[0001] The present invention relates to the field of running shoes, and specifically refers to a carbon plate - equipped muscle memory running shoe and its manufacturing process. Background Art

[0002] Running shoes, as the name implies, are shoes for running, specifically referring to the shoes most suitable for running. There are tens of thousands of running shoe brands. According to different performances and target users, running shoes are roughly divided into three categories: shock - absorbing running shoes, stability running shoes, and motion - control running shoes. However, the current running shoes have poor sole support. During running, the sole is prone to deformation, especially at the arch position of the sole. When the deformation is too large, the feet of the runner do not have sufficient support, and the feet bend with the sole, making it easy to sprain the ankle. At the same time, due to the poor sole support, it cannot provide an opposite acting force for the runner, making running more strenuous. Utility Model Content

[0003] The purpose of the present invention is to overcome the above - mentioned deficiencies and provide a carbon plate - equipped muscle memory running shoe and its manufacturing process.

[0004] On the one hand, the present invention discloses a carbon plate - equipped muscle memory running shoe, including a sole and an upper disposed on the sole. The upper includes a shoe - face part, a vamp part, a shoe opening, and a tongue opening. An installation groove is provided at the arch position of the bottom of the sole, and a carbon plate is installed in the installation groove, and the bottom of the installation groove is open.

[0005] Preferably, muscle memory tissues are provided on both sides of the heel of the sole. The muscle memory tissues include a plurality of arc - shaped grooves arranged side by side on the sole.

[0006] Preferably, a TPU wear - resistant layer is provided on the bottom surface of the sole.

[0007] Preferably, a plurality of shoelace holes for the shoelaces to pass through are provided on both sides of the tongue opening, and elastic adjusting devices are provided at positions on the upper corresponding to the shoelace holes. The elastic adjusting devices are used to adjust the tightness of the shoelaces.

[0008] Preferably, the elastic adjusting device includes a connecting piece with the bottom connected to the upper, a connecting tube disposed at the position of the shoelace hole, a telescopic spring sleeved on the connecting tube, and a collar movably sleeved at the end of the connecting tube. One end of the connecting tube is connected to the shoelace hole and the other end movably penetrates through the connecting piece. The telescopic spring is located between the upper and the connecting piece, the collar is located on the side of the connecting piece away from the shoelace hole. A strip - shaped groove is provided on the connecting tube, and a perforation that can communicate with the strip - shaped groove is provided at the top of the connecting piece.

At the same time, under the support of the carbon plate, when the athlete runs, it can provide a reaction force to the foot, making running more labor-saving and easier.

[0020] 2. When tying shoelaces for sports shoes, it is difficult to adjust the tightness of the shoelaces. Often, due to the shoelaces being tied too tightly, problems such as discomfort when wearing and trouble when taking off shoes occur. In this application, the shoelaces pass through the shoelace holes, connecting tubes, strip-shaped grooves, and perforations in sequence and extend outside the connecting piece. By rotating the collar, the top of the connecting piece can slide on the connecting tube under the elastic force of the telescopic spring. When the connecting piece moves, the corresponding shoelaces passing through the connecting piece will also move in the strip-shaped grooves of the connecting tube, and then under the elastic force of the telescopic spring, elastic clamping is achieved. When the collar is rotated in the opposite direction, the connecting piece can be driven to compress the telescopic spring, so that the entire shoelace will change from a tight state to a loose state, thus adjusting the tightness of the entire shoelace. On the one hand, it is convenient for comfortable wearing, and on the other hand, it is convenient for taking off shoes. Description of the Drawings

[0030] Embodiment 1

[0031] This embodiment provides a muscle memory running shoe with a carbon plate 7. Refer to Figure 1 , including a sole 1 and an upper disposed on the sole 1. When the sole 1 is processed, EVA resin is used for processing. The EVA resin and other raw materials are injected into the sole 1 molding die, and then the die is heated to 174 °C. After a certain time, when the sole 1 foams and forms, the sole 1 is taken out of the die. Refer to Figure 2 , and the carbon plate 7 is bonded in the installation groove 6 on the bottom surface of the sole 1; an installation groove 6 is provided at the position of the arch of the bottom of the sole 1, the carbon plate 7 is located in the installation groove 6, and the bottom of the installation groove 6 is open-shaped, which can reduce the production cost. Under the action of the carbon plate 7, the arch of the sole 1 has good support, so that when running, the arch of the sole 1 will not bend and deform, preventing the runner from spraining the ankle. At the same time, under the support of the carbon plate 7, when the runner runs, a reaction force can be provided to the foot, making running more labor-saving and easy; when the upper is processed, the fabric of the upper is cut to form the upper, and then the upper and the sole 1 are bonded by hot melt adhesive; the upper includes a shoe face part 2, a vamp part 3, a shoe mouth 4 and a tongue opening 5. After the sole 1 is formed, muscle memory tissues are formed on both sides of the heel of the sole 1. The muscle memory tissues include a plurality of arc grooves 8 arranged side by side on the sole 1. Under the action of the arc grooves 8, when the sole 1 is deformed by force, a space for the deformation of the sole 1 can be provided, and then the resilience of the sole 1 can be improved; and a TPU wear-resistant layer 9 is bonded to the bottom surface of the sole 1 by hot melt adhesive. Under the action of the TPU wear-resistant layer 9, the wear resistance of the entire sole 1 can be improved. The vamp part 3 on both sides of the upper is coated with a coating to form a coating layer 18, which improves the support of the vamp part 3 of the upper. And when coating, a mixture of polypropylene and polyethylene is used for coating, and the softness of the coating layer 18 can be controlled by controlling polypropylene and polyethylene, so that wearing is more comfortable under the action of the coating layer 18.

[0032] Embodiment 2

[0033] The difference between this embodiment and Embodiment 1 is that: on both sides of the tongue opening 5 of the shoe, there are several shoelace holes 10 through which the shoelaces can pass. In each shoelace hole 10, there is a lace passer 17. The lace passer 17 includes a sleeve 171 arranged in the shoelace hole 10, a plurality of ball grooves 172 annularly arranged on the inner wall of the sleeve 171, and a plurality of rolling balls 173 rotatably arranged in each ball groove 172. A part of each rolling ball 173 extends into the sleeve 171. Under the action of the roller, the friction between the shoelace and the shoelace hole 10 can be reduced, making the shoelace pull more smoothly. And at the positions on the shoe upper corresponding to each shoelace hole 10, there is an elastic adjustment device 11, which is used to adjust the tightness of the shoelace; Refer to Figure 3 , specifically, the elastic adjustment device 11 includes a connecting piece 111 whose bottom is connected to the shoe upper, a connecting pipe 112 arranged at the position of the shoelace hole 10, a telescopic spring 113 sleeved on the connecting pipe 112, and a collar 114 movably sleeved on the end of the connecting pipe 112. The surface of the connecting pipe 112 is provided with an external thread, and the inner wall of the collar 114 is provided with an internal thread. The collar 114 is threadedly connected to the connecting pipe 112. The collar 114 can be rotated on the connecting pipe 112. One end of the connecting pipe 112 is connected to the shoelace hole 10 and is in communication, and the other end movably penetrates through the connecting piece 111. The telescopic spring 113 is located between the shoe upper and the connecting piece 111. The collar 114 is located on the side of the connecting piece 111 away from the shoelace hole 10. The connecting pipe 112 is provided with a strip-shaped groove 12, and the top of the connecting piece 111 is provided with a through hole 13 that can be in communication with the strip-shaped groove 12. The shoelace can pass through the shoelace hole 10, the connecting pipe 112, the strip-shaped groove 12, and the through hole 13 in sequence and extend outside the connecting piece 111. By rotating the collar 114, the top end of the connecting piece 111 can slide on the connecting pipe 112 under the elastic force of the telescopic spring 113. When the connecting piece 111 moves, the corresponding shoelace passing through the connecting piece 111 will also move in the strip-shaped groove 12 of the connecting pipe 112, and then under the elastic force of the telescopic spring 113, elastic clamping is achieved. When the collar is rotated in the opposite direction, the connecting piece 111 can be driven to compress the telescopic spring 113, so that the whole shoelace will change from a tight state to a loose state, and thus the tightness of the whole shoelace can be adjusted. On the one hand, it is convenient for comfortable wearing, and on the other hand, it is convenient for taking off shoes.

[0034] Refer to Figure 4, annular grooves 15 are provided on the surfaces of each ring sleeve. Drawstrings 16 are provided on both sides of the tongue opening 5. Each drawstring 16 is connected to each of the corresponding sleeve rings 114 on one side. Specifically, one end of the drawstring 16 is fixedly connected to the annular groove 15 of a sleeve ring 114 located on the outermost side, and the other end is sequentially wound in the annular grooves 15 of each ring sleeve and is fixedly connected to the annular groove 15 of another sleeve ring 114 on the outermost side. When it is necessary to uniformly adjust the elastic adjustment devices 11 on each shoelace hole 10, only the outermost sleeve ring 114 needs to be rotated. When the outermost sleeve ring 114 rotates, the drawstring 16 is wound up, and the other sleeve rings 114 are pulled to rotate through the drawstring 16, thereby facilitating the quick adjustment of multiple elastic adjustment devices 11 at the same time and improving the adjustment efficiency of the shoelace tightness adjustment.
