Description

Technical Field

[0001] This utility model relates to the field of footwear technology, and in particular to a double-wing anti-rollover structure and a shoe. Background Technology

[0002] Athletic or casual shoes generally consist of a sole and an upper mounted on the sole, forming a cavity to house the foot. Due to limitations in the material properties of the upper, the lateral support is often insufficient, especially during strenuous activities like basketball and soccer. This lack of support becomes particularly pronounced when the foot experiences significant impact or torsional forces, increasing the risk of ankle sprains and twists. Furthermore, some soles have design flaws that allow the impact of each step, such as during running, to deform, hindering the absorption and transfer of force and impacting athletic efficiency. This can also lead to foot fatigue, especially in the arch, and potentially injury. Therefore, the inventors of this invention conducted in-depth research into these issues, resulting in this invention. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a double-wing anti-rollover structure and shoe to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A double-wing anti-rollover structure is applied to a shoe, the shoe including a sole and an upper, the sole having an extension extending upward from its side, and the sole having a first support piece and a second support piece with a wing-shaped structure on its side, the first support piece including a support band located on the side of the sole near the bottom, the front and rear ends of the support band being connected to connecting wings with a Z-shaped structure; the second support piece including an M-shaped support wing inclined towards the toe, the top bend of the support wing extending towards the toe with a support arm; the support arm is located on the extension.

[0006] Furthermore, the support arm is located above the top of the connecting wing, and the bent portion of the support wing toward the toe and the bent portion of the connecting wing toward the heel are aligned, forming a Z-shaped partition between them.

[0007] Furthermore, the side of the sole is provided with a first mounting groove and a second mounting groove for respectively mounting the first support piece and the second support piece.

[0008] Furthermore, the sidewalls of the first mounting groove and the second mounting groove are respectively provided with fixing grooves with an arc-shaped longitudinal section, and the sidewalls of the first support plate and the second support plate are respectively provided with protruding edges that are adapted to and engaged with the fixing grooves, and the longitudinal section of the protruding edges is an arc-shaped structure.

[0009] Furthermore, both the first support sheet and the second support sheet are composed of a straight inner bottom layer and an arc-shaped outer outer layer, with a buffer cavity formed between the inner bottom layer and the outer outer layer.

[0010] Furthermore, one or more supports are provided inside the buffer cavity.

[0011] Furthermore, the buffer cavity is provided with two symmetrically arranged V-shaped supports with openings facing each other, and the two ends of the openings of the supports are respectively connected to the inner bottom layer and the outer surface layer.

[0012] Furthermore, an arc-shaped support is provided inside the buffer cavity. The opening of the support faces the outer surface layer, and its top two ends are connected to the outer surface layer. One end of its arc-shaped bottom is connected to or not connected to the inner bottom layer.

[0013] Furthermore, the bottom surface of the shoe sole has a diamond-shaped shoe sole groove, and a diamond-shaped carbon plate is installed in the shoe sole groove by adhesive. A connecting ring is glued around the bottom edge of the carbon plate, and the connecting ring is glued to the side wall of the shoe sole groove.

[0014] This utility model also proposes a shoe, including a sole and an upper, including the aforementioned double-wing anti-rollover structure.

[0015] Beneficial effects

[0016] Compared to existing technologies, this invention offers at least the following advantages: The first and second support plates with wing-shaped structures provide lateral support to the shoe from the toe to the heel, effectively preventing the foot from rolling outwards, reducing the risk of injury, and maintaining the shape of the sole side to prevent excessive deformation and collapse. When walking or exercising, the heel changes shape as it lifts and lowers. The design of the bending sections of the first and second support plates provides necessary support without restricting normal foot movement, reducing pressure on the foot, improving comfort, and absorbing energy like a spring when the foot lands, thus providing cushioning and making exercise more comfortable. The buffer cavity formed inside the first and second support plates provides a certain space for compression deformation, which absorbs some external force and prevents the force from acting directly on the foot. The support structure inside the buffer cavity disperses the pressure on the first and second support plates, preventing damage or excessive deformation. The carbon fiber plate fixed in the sole has high strength and toughness, which improves the torsional resistance of the sole. During exercise, the carbon fiber plate keeps the sole in a stable shape, avoids excessive twisting, and provides stable support for the feet. Attached Figure Description

[0030] See Figures 1-9This embodiment provides a double-wing anti-rollover structure applied to a shoe, which includes a sole 2 and an upper 1. An extension portion 22 extends upward from the side of the sole 2. A first support piece 3 and a second support piece 4 with wing-shaped structures are provided on the side of the sole 2. The first support piece 3 includes a support band 30 located near the bottom of the sole side. The front and rear ends of the support band 30 are connected to the two ends of a Z-shaped connecting wing 31. The second support piece 4 includes an M-shaped support wing 41 inclined towards the toe. A support arm 40 extends from the top bend of the support wing 41 towards the toe. The support arm 40 is located at the top of the extension portion 22, and its top profile matches the top profile of the extension portion 22. The support arm 40 is located above the top of the connecting wing 31, and the bent portion of the support wing 41 towards the toe and the bent portion of the connecting wing 31 towards the heel are aligned, forming a Z-shaped partition 24 between them. This partition 24 serves as a buffer zone, allowing for a certain degree of relative displacement between the first support piece 3 and the second support piece 4 when the foot is subjected to a large impact force, absorbing part of the impact force and reducing the impact on the foot. Furthermore, this partition allows the first support piece 3 and the second support piece 4 to flexibly adjust the support angle and force according to changes in the foot's position.

[0031] Preferably, the side of the sole 2 is provided with a first mounting groove 20 and a second mounting groove 21 for respectively mounting the first support piece 3 and the second support piece 4. The first support piece 3 and the second support piece 4 are respectively glued to the first mounting groove 20 and the second mounting groove 21, so that the first support piece 3 and the second support piece 4 are firmly fixed to the side of the sole 3. Of course, in other embodiments, the first support piece 3 and the second support piece 4 can be fixed in the first mounting groove 20 and the second mounting groove 21 by sewing. The outline of the first mounting groove 20 and the second mounting groove 21 is consistent with the first support piece 3 and the second support piece 4. Preferably, the sidewalls of the first mounting groove 20 and the second mounting groove 21 are respectively provided with fixing grooves 11 with an arc-shaped longitudinal section. The two sidewalls of the first support piece 3 and the second support piece 4 are respectively provided with protruding edges 10 that are adapted to and engage with the fixing grooves 11. The longitudinal section of the protruding edges 10 is an arc-shaped structure.

[0032] like Figure 5 As shown, in one embodiment of the technical solution of this embodiment, the first support plate 3 and the second support plate 4 are both composed of a straight inner bottom layer 8 and an arc-shaped outer outer layer 9, and a buffer cavity is formed between the inner bottom layer 8 and the outer outer layer 9.

[0033] like Figure 6As shown, another embodiment of the first support plate 3 and the second support plate 4 in this technical solution is as follows: Both the first support plate 3 and the second support plate 4 are composed of a straight inner bottom layer 8 and an arc-shaped outer outer layer 9, forming a buffer cavity between the inner bottom layer 8 and the outer outer layer 9. Two symmetrically arranged V-shaped support bodies 5 with openings facing each other are disposed within the buffer cavity, and the two ends of the openings of the support bodies 5 are respectively connected to the inner bottom layer 8 and the outer outer layer 9.

[0034] like Figure 7 As shown, another embodiment of the first support plate 3 and the second support plate 4 in this technical solution is as follows: Both the first support plate 3 and the second support plate 4 are composed of a straight inner bottom layer 8 and an arc-shaped outer outer layer 9, forming a buffer cavity between the inner bottom layer 8 and the outer outer layer 9. An arc-shaped support body is disposed in the buffer cavity, with the opening of the support body facing the outer outer layer, its top two ends connected to the outer outer layer, and one end of its arc-shaped bottom connected to or not connected to the inner bottom layer.

[0035] In this embodiment, the bottom surface of the sole 2 is provided with a diamond-shaped sole groove 23. A diamond-shaped carbon plate 7 that is compatible with the sole groove 23 is installed in the sole groove 23 by adhesive. A connecting ring 6 is glued around the bottom edge of the carbon plate 7 by adhesive. The connecting ring 6 is glued to the side wall of the sole groove 23 by adhesive.

[0036] It should be noted that in this embodiment, the first support sheet 3 and the second support sheet 4 are made of TPU material.

[0037] This utility model also proposes a shoe, including a sole 2 and an upper 1, and also includes a double-wing anti-rollover structure as described above.

[0038] When worn, the first support piece 3 and the second support piece 4 of the wing-shaped structure provide lateral support to the shoe from the toe to the heel, effectively preventing the foot from rolling outwards and reducing the risk of injury. Simultaneously, they maintain the shape of the sole's side, preventing excessive deformation and collapse. The connection structure of the support band 30 and the Z-shaped connecting wing 31 of the first support piece 3 results in one bend near the toe and three consecutive bends near the heel. Similarly, the second support piece 4, composed of a support arm 41 and an M-shaped support wing 40, has three consecutive bends. During walking or exercise, the heel changes shape as it lifts and lowers. The design of the bends in the first and second support pieces 3 and 4 provides necessary support without restricting normal foot movement, reducing pressure on the foot and improving comfort. Furthermore, upon impact with the foot landing, the bends deform like a spring to absorb energy, acting as a cushion, and then return to their original shape. This reduces vibration transmitted to the foot during exercise, making exercise more comfortable. When foot movement requires changes in direction and angle, the flexing parts can flexibly adapt to these changes, providing dynamic support and elastic feedback. The first and second support plates, forming internal cushioning cavities, provide space for compression deformation under external pressure. This deformation absorbs some of the external force, preventing direct force on the foot. Supports within the cushioning cavities disperse the pressure on the first and second support plates, preventing damage or excessive deformation. The carbon fiber plate fixed to the sole possesses high strength and toughness, providing excellent torsional resistance. During exercise, the carbon fiber plate helps the sole maintain a stable shape, preventing excessive twisting and providing stable support for the feet.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
