Description

Technical Field

[0001] The invention belongs to the technical field of soles, and in particular relates to an anti-slip structure, a sole and applications thereof. Background Art

[0002] As the core component where the human body comes into contact with the ground, the sole is widely used in outdoor sports equipment, industrial protective shoes and boots, special operation equipment and other fields, providing users with grip, stability and protection. In extreme environments such as mountaineering, cross-country running, and snow exploration, the anti-slip performance of the sole is directly related to the life safety and work efficiency of the athlete. In such outdoor scenes, the sole needs to cope with a variety of complex terrains such as ice and snow, slippery rocks, and muddy mountain roads at the same time, which puts higher requirements on anti-slip technology.

[0003] When exploring snowy terrain, existing climbing shoes use designs such as steel nail implants and serrated patterns to enhance grip on ice and snow terrain, but they still have technical defects. Although fixed steel nails can be temporarily embedded in the ice surface, they will produce rigid collisions when in contact with hard surfaces (such as exposed rocks and frozen soil), and cannot adapt to the uneven conditions of various terrains. This not only causes a strong sense of vibration when walking, but also easily causes foot fatigue after long-term use. In addition, in the event that some steel nail components are damaged, since the steel nails are fixed to the soles, replacement is complicated, and physical strength needs to be conserved in extreme environments to cope with the challenges of extreme environments. They cannot be quickly disassembled and adjusted, resulting in a poor user experience.

[0004] For example, in the prior art, publication number TW200608911A is also a shoe with anti-skid accessories, but it needs to manually adjust the expansion and contraction of the sole to control the friction with the ground, which is extremely inconvenient.

The additional anti-slip grooves 22 further increase the contact area between the anti-slip structure and the ground.

[0073] In order to make the nail assembly firmly embedded in the anti-slip structure, the anti-slip structure is mainly prepared with rare earth butadiene rubber and nitrile butadiene rubber. Rare earth butadiene rubber has extremely high elasticity and crystallization speed, good molecular chain flexibility, outstanding wear resistance and low wear, and is especially suitable for high-frequency friction scenarios where the sole contacts the ground for a long time. Nitrile butadiene rubber has high tear strength and tensile strength, which can enhance the anti-destruction ability of the edge and bending parts of the sole and prolong the service life. The two complement each other in performance, so that the tear strength, tensile strength, elongation and wear resistance of the anti-slip structure are doubled. Among them, the various properties of the anti-slip structure are as follows: Tear strength>8kN / m Tensile strength>180kg / cm² Elongation>600% Abrasion resistance DIN <90mm³.

[0074] Example 2 For the sake of simplicity in description, the same parts as those in Example 1 will not be described in detail, and the structure different from Example 1 of the present invention will be mainly described. The difference between Example 2 and Example 1 lies in the setting of the adaptive shock absorption of the anti-slip structure.

[0075] Figure 4 FIG. 2 is a partial cross-sectional view of an anti-slip structure according to another embodiment of the present invention. Figure 4 As shown, the shock-absorbing and anti-slip effect of another embodiment of the present invention will be described in detail.

[0076] Fig.10 is an exploded cross-sectional view of an embedded nail assembly according to another embodiment of the present invention, Fig.11 FIG. 2 is a combined cross-sectional view of an embedded nail assembly according to another embodiment of the present invention. Fig.10 and Fig.11 As shown, the combined structure of an embedded nail assembly according to another embodiment of the present invention will be described in detail.

[0077] In order to improve the anti-slip force, the body 2 includes a first surface for contacting the ground and a second surface attached to the midsole of the sole, wherein the embedded replaceable shock-absorbing and anti-slip device is arranged on the first surface of the body 2; Among them, when the embedded nail component 1 is installed in the engaging groove 212, the nail component 1 extends from the main body 2 of the anti-slip structure toward the ground to a height between the first height H1 and the second height H2, which is used to provide an adaptive second anti-slip force. When the foot contacts the ground, the nail component 1 contacts the ground first to provide the second anti-slip force. When the nail component 1 contacts various uneven ground surfaces (such as snow layers, dirt roads, rocky dirt roads or ice surfaces, etc.), the retractable anti-slip part 13 arranged inside the nail component 1 can adapt to the uneven conditions of different ground surfaces to provide stronger anti-slip force. Secondly, the anti-slip unit 21 contacts the ground to provide the first anti-slip force, providing more contact area with the ground, double anti-slip, suitable for contacting different uneven surfaces (such as snow layers, dirt roads, rocky dirt roads or ice surfaces) in some extreme environments, and providing reliable anti-slip effect.

[0078] In order to adapt to the uneven conditions of various terrains, the anti-slip part 13 includes an anti-slip nail 131. The outer wall of the anti-slip nail 131 is radially extended to provide a limiting flange 133 that is compatible with the positioning groove 123. The anti-slip part 13 also includes a spring 132. One end of the spring 132 is embedded in the first accommodating groove 113, and the other end is sleeved on the anti-slip nail 131 and abuts against the top surface of the limiting flange 133. The anti-slip nail 131 is embedded in the positioning groove 123 and one end passes through the through hole 124, and the other end is telescopically arranged in the second accommodating groove 122 through the spring 132. Through the elastic deformation of the spring 132, the anti-slip nail 131 can realize adaptive feedback to different terrain changes and the rise and fall of the center of gravity of the sole.

[0079] In order to achieve adaptive shock absorption, in the walking process, when the anti-skid structure contacts the ground, the spring 132 of the nail assembly 1 performs adaptive elastic deformation to the change of the center of gravity during the walking process to provide a height between the first height H1 and the second height H2. When walking on (such as snow, dirt road, rocky dirt road), the center of gravity of the sole is first gathered at the rear palm position. At this time, the nail assembly 1 located at the rear palm first contacts the ground. Due to the effect of pressure, the anti-skid nail 131 is elastically deformed by the spring 132 and retracted into the second accommodating groove 122. When the center of gravity of the sole is transferred to the fore palm, the nail assembly 1 of the fore palm responds to the pressure, and the anti-skid nail 131 is elastically deformed by the spring 132 and retracted into the second accommodating groove 122. In this process, due to the different uneven conditions of the ground, when the anti-skid nail 131 of any nail assembly 1 is protruding relative to the ground, the elastic deformation of the spring 132 is relatively large, and the retraction amount of the spring 132 is also relatively large, thereby providing a height H3 between the first height H1 and the second height H2; when the anti-skid nail 131 of another nail assembly 1 is recessed relative to the ground, the elastic deformation of the spring 132 is relatively small, and the retraction amount of the spring 132 is also relatively small, thereby providing a height H4 between the first height H1 and the second height H2. At this time, the adaptive conditions of any two nail assemblies 1 of the sole to the ground are expressed as heights H3 and H4 (H4 is greater than H3) between the first height H1 and the second height H2, thereby completing the adaptive conditions of different uneven conditions of the ground (when walking on any uneven ground, any nail assembly 1 will adapt to the ground through the spring 132 and provide a height Hn between the first height H1 and the second height H2, and Hn satisfies H1≤Hn≤H1+H2); The shock absorption effect is dynamically adjusted according to different walking states (such as the rear palm landing first or the fore palm landing first) to reduce the direct transmission of impact force to the foot. The spring 132 continuously makes elastic deformation according to the change of the center of gravity, which effectively buffers the impact force of the ground on the sole of the foot during walking, and greatly reduces the burden on joints such as the knees and ankles during walking. When walking on complex terrains such as snow, dirt roads, rocky dirt roads, etc., it can also make real-time adjustments according to the change of the center of gravity to prevent slipping, thereby improving walking comfort and stability. Whether it is starting, accelerating, decelerating or turning during exercise, it can provide reliable anti-slip protection.

[0080] [Sole according to an embodiment of the present invention] Example 1 Fig.15 is a side view of a sole according to an embodiment of the present invention, Fig.16 is a top view of a midsole according to an embodiment of the present invention, Fig.15 and Fig.16 As shown, the midsole structure according to the embodiment of the present invention will be described in detail.

[0081] As another aspect of the present invention, a sole is provided, which also includes a midsole 4, wherein the midsole 4 has a first surface for contacting a foot surface and a second surface for contacting an anti-slip structure, wherein the second surface contacts the anti-slip structure of any one of the above-mentioned items, wherein the second surface of the midsole 4 has at least one groove 411 adapted to the protrusion 213 for accommodating the protrusion 213.

[0082] Fig.17 is a top view of a midsole according to an embodiment of the present invention, Fig.17 As shown, the groove structure according to the embodiment of the present invention will be described in detail.

[0083] In order to provide sufficient space, the groove 411 is used to provide space for accommodating the protrusion 213, and the depth of the space is positively correlated with the height of the protrusion 213 of the nail assembly 1. When the height of the embedded nail assembly 1 is higher, the height of the protrusion 213 is higher, and the depth of the groove 411 is correspondingly deeper. At the same time, the cooperation between the groove 411 and the protrusion 213 can increase the friction force of the contact surface, ensuring that the protrusion 213 can be firmly embedded in the groove 411, thereby forming a greater friction resistance between the contact surfaces to prevent sliding.

[0084] In order to improve the durability of the sole, the main body 2 and the midsole 4 are bonded by gluing, hot melting or stitching, which can ensure the bonding strength and stability between the main body 2 and the midsole 4, while improving the durability and production efficiency of the shoes.

[0085] Fig. 9 Schematic diagram of the anti-slip structure according to an embodiment of the present invention Fig. 9As shown, the overall structure of the anti-slip structure according to an embodiment of the present invention will be described in detail.

[0086] In order to evenly distribute the force on the sole, the embedded nail assembly 1 is arranged in the anti-slip unit 21 in a fractal geometric arrangement manner with at least two nail assemblies 1 as the center on the forefoot of the sole, so as to provide a driving force for the forefoot area of ​​the sole that requires greater grip during exercise (such as walking on a muddy road, climbing a mountain, or walking on ice). The embedded nail assembly 1 is arranged in the anti-slip unit 21 in a fractal geometric arrangement manner with at least one nail assembly 1 as the center on the rear sole of the sole, so as to provide the stability required in the rear sole area of ​​the sole during exercise (such as walking on a muddy road, climbing a mountain, or walking on ice) to disperse the impact force, and at the same time conform to the force distribution characteristics of the human body during exercise, so that the sole can maintain good grip and stability in various sports scenarios.

[0087] In order to improve production efficiency, the main body 2, midsole 4 and nail assembly 1 are processed in layers. The main body 2 and the midsole 4 can be processed first, and then the nail assembly 1 and the main body 2 are processed and assembled. The processing is convenient and fast during production. Each component can be processed separately with high precision to avoid losses caused by overall processing, thereby significantly improving product yield, reducing material waste, and reducing production costs.

[0089] As another aspect of the present invention, an application of an anti-slip structure is provided, which includes an application body, and any one of the anti-slip structures described above which is embedded and replaceably installed on the application body.

[0090] In this embodiment, the device can be specifically applied to a trekking pole. The device can effectively absorb the impact force when the trekking pole contacts the ground, and reduce the amplitude of the vibration transmitted to the wrist and shoulder of the user. It can also be applied to anti-slip gloves. On smooth ice or steep rocks, the anti-slip gloves equipped with the device can provide additional grip, significantly increase friction, and prevent the hands from sliding. It can also be applied to the soles of robots. When the robot is walking, by setting the device on the soles of its feet, it can provide additional grip, significantly increase friction, prevent sliding, and avoid falling due to the slippery ground when moving; It can also be applied to the bottom of an outdoor camping box. When camping outdoors in the snow and ice, by setting the device at the bottom of the outdoor box, it can provide additional grip, significantly increase friction, and prevent the box from sliding during movement or use. It can also be applied to the tires of toy cars. When players control toy cars, taking remote control cars as an example, by setting this device on the tires, the grip and stability of the vehicle on various terrains can be improved, making the vehicle less likely to slip during remote control driving, and better maintaining the balance and control of the toy vehicle, even on wet or muddy roads.

[0091] [Usage of the sole with anti-slip structure according to the embodiment of the present invention] How to use the anti-slip structure sole A When used on ice, the spike assembly 1 is installed on the outsole, so that a strong anti-skid force can be provided on the ice. Specifically, the anti-skid spikes 131 of the spike assembly 1 first contact the ground to provide a second anti-skid force, thereby increasing the contact area with the ice. The spike assembly 1 can penetrate the ice surface and contact the lower layer of the ice surface to provide a stronger anti-skid force. Secondly, the anti-skid unit 21 contacts the ice surface to provide a first anti-skid force, providing more contact area with the ground, and achieving double anti-skid. The spring 132 is arranged to adapt to different concave and convex ice surfaces to adapt to the ice surface, thereby effectively improving the anti-skid effect on the ice surface.

[0092] How to use the non-slip structure sole B When used on rocky and dirt roads, the spike assembly 1 is installed on the outsole, so that a strong anti-skid force can be provided on rocky and dirt roads. Specifically, the anti-skid spikes 131 of the spike assembly 1 first contact the ground to provide a second anti-skid force, thereby increasing the contact area with the rocky and dirt road to provide a stronger anti-skid force. Secondly, the anti-skid unit 21 contacts the rocky and dirt road to provide a first anti-skid force, providing more contact area with the ground, and double anti-skid. Through the set spring 132, it can adapt to rocks with different contours to adapt to rocky and dirt roads, effectively improving the anti-skid effect on rocky and dirt roads.

[0093] When walking or exercising on uneven surfaces, any of the nail components 1 will adapt to the ground through the spring 132. The spring 132 continuously elastically deforms according to the change in the center of gravity, providing a height Hn between the first height H1 and the second height H2. Hn satisfies H1≤Hn≤H1+H2, which effectively buffers the impact of the ground on the sole of the foot when walking, and makes real-time adjustments based on the change in the center of gravity and the unevenness of the ground, providing a strong anti-slip force and reliable sports protection.
