Description

TECHNICAL FIELD

[0001] The present invention belongs to the technical field of shoe soles, and particularly relates to an anti-slip structure, shoe sole and applications thereof.

BACKGROUND

[0002] As the core component for contact between the human body and ground, shoe soles are widely applied in fields such as outdoor sports equipment, industrial protective footwear, and specialized operational equipment, providing users with grip, stability and protection. In extreme environments such as mountaineering, trail running, and snow exploration, the anti-slip performance of shoe soles directly relates to the life safety and operational efficiency of users. In such outdoor scenarios, the shoe sole must simultaneously address multiple complex terrains including ice and snow, wet slippery rocks, and muddy mountain paths, which poses higher requirements for anti-slip technology.

[0003] During snow expedition scenarios, existing climbing shoes, although strengthening grip on ice and snow terrain through steel stud implantation and serrated treads, still exhibit technical deficiencies. Fixed steel studs, while capable of temporarily embedding into ice surfaces, generate rigid collisions when contacting hard surfaces (such as exposed rocks and frozen ground), failing to adapt to the undulations of various terrains. This not only results in intense walking vibrations but also leads to foot fatigue during prolonged use. Furthermore, in cases where some steel stud assemblies are damaged, replacement becomes complex due to the studs being fixed to the shoe sole. In extreme environments where energy conservation is essential to meet extreme environmental challenges, rapid disassembly and adjustment cannot be performed, resulting in poor user experience.

[0004] As disclosed in the prior art, publication number TW200608911A also relates to footwear having anti-slip accessories, however such footwear requires manual adjustment of the shoe sole's extension and retraction to control the friction force against the ground, which is extremely inconvenient. Therefore, designing a shoe sole with an anti-slip structure to resolve the aforementioned problems is of particular importance.

In the specific embodiments

[Anti-slip Structure According to Embodiments of the Present Invention]

Embodiment 1

[0049] Figure 1 is a structural schematic diagram of the anti-slip structure according to an embodiment of the present invention. As shown in Figure 1, the structure of the anti-slip structure according to the present invention will be described in detail.

[0050] Figure 2 is an overall structural schematic diagram of the embedded stud assembly according to an embodiment of the present invention, and Figure 3 is a partial cross-sectional view of the anti-slip structure according to an embodiment of the present invention. As shown in Figures 2 and 3, the overall structure of the anti-slip structure according to embodiments of the present invention will be described in detail.

[0051] Describes an anti-slip structure according to an embodiment of the present invention, which comprises a body 2, wherein on the body 2 an embedded replaceable shock-absorbing anti-slip device for shock absorption and anti-slip function is detachably arranged, which comprises an embedded stud assembly 1, the embedded stud assembly 2 comprises a guide element 11 movably arranged up and down, a fixed base 12, and an anti-slip portion 13 arranged between the guide element 11 and the fixed base 12, the guide element 11 is configured to guide and engage the shock-absorbing anti-slip device, the fixed base 12 is configured to prevent detachment of the shock-absorbing anti-slip device, the anti-slip portion 13 is configured to prevent slipping and grip the ground when contacting the ground.

[0052] Wherein the body 2 comprises a first surface for contacting the ground and a second surface attached to the midsole of the shoe sole, wherein the embedded replaceable shock-absorbing anti-slip device is arranged on the first surface of the body 2.

[0053] Wherein the first surface comprises anti-slip units 21 extending from the body 2 of the anti-slip structure toward the ground at a first height H1 for providing first anti-slip force, when the foot contacts the ground, the anti-slip units 21 are capable of making initial contact with the ground, thereby increasing the contact area with the ground and closely conforming to the uneven structure of the ground, such that the friction force of the first surface of the anti-slip structure for contacting the ground is increased, thereby preventing slipping.

[0054] Wherein, at least one anti-slip unit 21 comprises an anti-slip block 211, the anti-slip block 211 having an engagement groove 212 formed therein for detachably installing the embedded stud assembly 1.

[0055] In order to improve anti-slip force, with the embedded stud assembly 1 installed in the engagement groove 212, the stud assembly 1 extends from the body 2 of the anti-slip structure toward the ground by a second height H2 for providing a second anti-slip force. When the foot contacts the ground, the stud assembly 1 makes initial contact with the ground, providing the second anti-slip force and increasing the contact depth with the ground. The stud assembly 1 can penetrate the ground layer (such as snow layer, mud, or ice surface) to directly contact the underlying ground layer, thereby providing stronger anti-slip force. Subsequently, the anti-slip unit 21 contacts the ground to provide the first anti-slip force, providing greater contact area with the ground. This dual anti-slip protection is suitable for contacting hard grounds in extreme environments (such as exposed rock or frozen ground), providing reliable anti-slip performance.

[0056] Figure 5 is an exploded cross-sectional view of the embedded stud assembly according to the embodiment of the present invention. As shown in Figure 5, the structure of the embedded stud assembly according to the embodiment of the present invention will be described in detail.

[0057] In order to improve the stability of anti-slip grip, the guide element 11 comprises a first contact portion 111 and a first connecting portion 112 arranged at the bottom of the first contact portion 111, wherein the first connecting portion 112 has a first receiving groove 113 formed therein, the fixed base 12 is arranged at the bottom of the guide element 11 and comprises a seat body 121 and a second receiving groove 122 arranged in the seat body 121, a positioning groove 123 is coaxially provided at the bottom of the second receiving groove 122, a through hole 124 is provided on the bottom surface of the seat body 121, wherein the first connecting portion 112 is movably arranged in the second receiving groove 122, and the through hole 124 and the positioning groove 123 are axially communication with each other, so that the fixed base 12 forms a structure in which the upper and lower portions are in communication with each other.

[0058] Figure 6 is an exploded view of the embedded stud assembly according to an embodiment of the present invention. As shown in Figure 6, the connection method of the embedded stud assembly according to the present invention will be described in detail.

[0059] To improve stability, the outer wall of the first connecting portion 112 is provided with a first limiting ring, and the inner wall of the second receiving groove 122 is provided with a second limiting ring that is buckled and fitted with the outer wall of the first connecting portion 112.

[0060] Figure 7 is a cross-sectional view of the fixed base of the embedded stud assembly according to an embodiment of the present invention. As shown in Figure 7, the structure of the seat body according to the embodiment of the present invention will be described in detail.

[0061] To engage the anti-slip portion 13, the second receiving groove 122 has a diameter larger than the positioning groove 123, and the positioning groove 123 has a diameter larger than the through hole 124. The positioning groove 123 is configured to fit with the anti-slip portion 13 to enhance its stability and prevent loosening.

[0062] Figure 6 shows an exploded view of the embedded stud assembly according to an embodiment of the present invention, and Figure 8 shows an assembled cross-sectional view of the embedded stud assembly according to an embodiment of the present invention. As shown in Figures 6 and 8, the assembled structure of the embedded stud assembly according to an embodiment of the present invention will be described in detail.

[0063] To improve stability, the anti-slip portion 13 comprises an anti-slip stud 131, wherein the outer wall of the anti-slip stud 131 is provided with a limiting flange 133 extending radially and adapted to the positioning groove 123. The anti-slip stud 131 is fixedly embedded within the positioning groove 123 with one end penetrating through the through hole 124 and the other end extending into the first receiving groove 113 and abutting against the top wall of the first receiving groove 113. By providing the limiting flange 133 on the outer wall of the anti-slip stud 131 and adapting it to the positioning groove 123, the anti-slip stud 131 can be firmly embedded within the positioning groove 123, avoiding displacement or loosening due to external forces during use, which not only enhances the overall stability of the anti-slip portion 13 but also effectively improves its service life.

[0064] Figure 2 is a schematic diagram of the overall structure of the embedded stud assembly according to an embodiment of the present invention.

The positioning groove 114 forms a recess in the radial direction to restrict axial movement thereof, preventing vibrational detachment during movement and improving stability.

[0069] To adapt to different scenario requirements, the material of the anti-slip portion 13 is selected from any one of steel, plastic, and carbon fiber, which can meet the needs of different application scenarios. By combining the advantages of various materials, the applicability and reliability of the device are enhanced, while also providing users with flexible selection options.

[0070] Figure 12 is a cross-sectional view of the engagement groove according to an embodiment of the present invention. As shown in Figure 12, the overall structure of the engagement groove according to an embodiment of the present invention will be described in detail.

[0071] To improve the stability of the anti-slip structure, the engagement groove 212 is a multi-layer structure, wherein a positioning block 215 adapted to the positioning groove 114 is arranged between the upper and lower layers of the engagement groove 212. The positioning block 215 divides the engagement groove 212 into an upper groove 2121 and a lower groove 2122 that are arranged one above other, with the shapes of the upper and lower layers respectively adapted to the first connecting portion 112 and the seat body 121. This provides dual-layer fixed protection in both longitudinal and transverse directions, effectively improving stability during movement and preventing slippage. This enables the anti-slip structure to maintain good traction under various ground conditions, such as wet and slippery or oily surfaces, effectively preventing slipping and enhancing user safety and comfort. Meanwhile, in cases where the stud assembly 1 is damaged, it can be quickly removed from the engagement groove 212.

[0072] To improve axial stability, when the stud assembly 1 is engaged into the engagement groove 212, the first contact portion 111 thereof is guided into the upper groove 2121, wherein the positioning block 215 and the positioning groove 114 mutually engage with each other to restrict axial movement of the stud assembly 1, thereby preventing slippage during movement.

[0073] To improve horizontal stability, when the stud assembly 1 is engaged into the engagement groove 212, the seat body 121 thereof cooperatively fits into the lower groove 2122, wherein the lower groove 2122 is a polygonal groove adapted to the seat body 121, thereby forming geometric constraints on the stud assembly 1 to restrict horizontal rotational movement of the stud assembly 1 and enhance the anti-detachment effect.

[0074] Figure 12 is a cross-sectional view of the engagement groove according to an embodiment of the present invention. As shown in Figure 10, the protrusion structure of the anti-slip structure according to an embodiment of the present invention will be described in detail.

[0075] In order to provide a space for accommodating the stud assembly 1, the bottom wall of the engagement groove 212 protrudes upward, forming a spherical protrusion on the top surface of the body 2, which provides a space for accommodating the stub assembly 1, the depth of the space being related to the height of the stub assembly 1.

[0076] Figure 13 is a partial enlarged view of the anti-slip structure according to an embodiment of the present invention. As shown in Figure 13, the structure of the prying groove of the anti-slip structure according to an embodiment of the present invention will be described in detail.

[0077] For convenient disassembly and replacement, a prying groove 214 is provided extending outward from the inner wall of any side of the engagement groove 212, wherein prying groove is used for quick disassembly and replacement of the stud assembly 1. When the stud assembly 1 is damaged, it can be quickly removed and replaced through the prying groove 214, thereby improving convenience.

[0078] Figure 14 is a structural schematic diagram of the installation and removal auxiliary tool according to an embodiment of the present invention. As shown in Figure 14, the structure of the installation and removal auxiliary tool according to an embodiment of the present invention will be described in detail.

[0079] For the convenience of disassembly and replacement, the anti-slip structure further comprises an installation and removal auxiliary tool 3 for installing and removing the embedded stud assembly 1, wherein the installation and removal auxiliary tool 3 comprises a prying portion 31 and a gripping portion 32, and the bottom of the gripping portion 32 is provided with a positioning hole 33 for auxiliary installation. During disassembly, grip the gripping portion 32 with hand, align the prying portion 31 with the prying groove 214, insert vertically into the groove, and then pull out vertically with force to disassemble the stud assembly 1. During installation, the stud assembly 1 can be directly picked up by hand, align one end of the guide element 11 with the engagement groove 212, and press vertically to complete installation. Alternatively, the auxiliary installation positioning hole 33 can be used by first embedding the portion of the anti-slip stud 131 at the bottom of the stud assembly 1 that protrudes from the through hole 124 into the positioning hole 33, then aligning with the engagement groove 212 and pressing vertically into it to complete replacement. Alternatively, first preliminarily engage and place the stud assembly 1 into the engagement groove 212, then align the positioning hole 33 of the installation and removal auxiliary tool 3 with the anti-slip stud 131 and press vertically, thereby providing multiple methods for disassembly and replacement, improving replacement convenience, and enabling rapid replacement in cases of component damage under extreme weather conditions.

[0080] Figure 1 is a structural schematic diagram of the anti-slip structure according to an embodiment of the present invention. As shown in Figure 1, the shock-absorbing anti-slip effect of the anti-slip structure according to the embodiment of the present invention will be described in detail.

[0081] In order to improve comfort and shock-absorbing effect, the anti-slip units 21 are respectively distributed in fractal geometry on the forefoot and rearfoot of the body 2, thereby dispersing plantar pressure to improve comfort. The anti-slip units 21 with fractal geometry distribution can ensure that the pressure in each area of the sole is uniformly distributed, thereby reducing situations of excessive local pressure and improving wearing comfort. At the same time, when the foot contacts the ground, they can fully absorb and disperse impact forces, enabling each anti-slip unit 21 to independently cushion impact forces, thereby reducing vibration received by the foot and providing better shock-absorbing effect.

[0082] To enhance the anti-slip effect, the bottom of the body 2 is further provided with a plurality of anti-slip treads 22 for enhancing anti-slip ground gripping, fully considering the usage requirements under different ground conditions, wherein the additionally provided anti-slip treads 22 further increase the contact area between the anti-slip structure and the ground.

[0083] To ensure stable engagement of the stud assembly with the anti-slip structure, the anti-slip structure is fabricated primarily from rare earth cis-polybutadiene rubber and nitrile rubber, wherein the rare earth cis-polybutadiene rubber exhibits extremely high elasticity and crystallization speed, excellent molecular chain flexibility, outstanding wear resistance performance and low wear volume, making it particularly suitable for high-frequency friction scenarios where the shoe sole is in long-term contact with the ground, while the nitrile rubber provides higher tear resistance strength and tensile strength, thereby enhancing the anti-damage capability of shoe sole edges and flexural regions and extending service life, characterized in that the two materials complement each other in performance such that the tear strength, tensile strength, elongation rate and wear resistance of the anti-slip structure are multiplied, wherein the performance parameters of the anti-slip structure are as follows:

Embodiment 2

[0084] For brevity of description, parts identical to those in Embodiment 1 will not be described redundantly. The following mainly describes structures different from Embodiment 1 of the present invention. The difference between Embodiment 2 and Embodiment 1 lies in the adaptive shock-absorbing configuration of the anti-slip structure.

[0085] Figure 4 is a partial sectional view of an anti-slip structure according to another embodiment of the present invention. As shown in Figure 4, the shock-absorbing anti-slip effect according to another embodiment of the present invention will be described in detail.

[0086] Figure 10 is an exploded cross-sectional view of an embedded stud assembly according to another embodiment of the present invention, and Figure 11 is an assembled cross-sectional view of an embedded stud assembly according to another embodiment of the present invention. As shown in Figures 10 and 11, the assembled structure of the embedded stud assembly according to another embodiment of the present invention will be described in detail.

[0087] To enhance anti-slip force, the body 2 comprises a first surface for contacting the ground and a second surface attached to the midsole of the shoe sole, wherein the embedded replaceable shock-absorbing anti-slip device is arranged on the first surface of the body 2.

[0088] Wherein, in a state where the embedded stud assembly 1 is installed in the engagement groove 212, the stud assembly 1 extends from the body 2 of the anti-slip structure toward the ground at a height between the first height H1 and the second height H2, configured to provide adaptive second anti-slip force; when the foot contacts the ground, the stud assembly 1 makes contact with the ground first, providing the second anti-slip force; when the stud assembly 1 contacts various uneven ground layers (such as snow layers, dirt roads, rocky soil roads or ice surfaces), the retractable anti-slip portion 13 arranged inside the stud assembly 1 can adapt to the uneven conditions of different ground layers to provide stronger anti-slip force; subsequently, the anti-slip unit 21 contacts the ground to provide the first anti-slip force, providing greater contact area with the ground for dual anti-slip protection, suitable for contact with uneven grounds in extreme environments (such as snow layers, dirt roads, rocky soil roads), thereby providing reliable anti-slip effect.

[0089] In order to adapt to the uneven conditions of various terrains, the anti-slip portion 13 comprises an anti-slip stud 131, wherein an outer wall of the anti-slip stud 131 is provided with a radially extending limiting flange 133 adapted to the positioning groove 123, the anti-slip portion 13 further comprises a spring 132, wherein one end of the spring 132 is embedded within the first receiving groove 113 and the other end is mounted on the anti-slip studs 131 and abuts against the top surface of the limiting flange 133, the anti-slip stud 131 is embedded within the positioning groove 123 with one end penetrating through the through hole 124 and the other end telescopically disposed within the second receiving groove 122 via the spring 132, whereby through elastic deformation of the spring 132, adaptive feedback of the anti-slip stud 131 to different terrain variations and rise and fall movements of the foot's center of gravity is achieved.

[0090] For adaptive shock absorption, during the walking process, when the anti-slip structure contacts the ground, the spring 132 of the stud assembly 1 undergoes adaptive elastic deformation in response to center of gravity changes during the walking process, providing a height between the first height H1 and the second height H2. When walking on surfaces such as snow layers, dirt roads, or rocky soil roads, the sole center of gravity initially concentrates at the rearfoot position, whereupon the stud assembly 1 located at the rearfoot first contacts the ground. Due to the applied pressure, the anti-slip stud 131 undergoes elastic deformation through the spring 132 and retracts into the second receiving groove 122. When the sole center of gravity transitions to the forefoot, the stud assembly 1 of the forefoot responds to the pressure, causing the anti-slip stud 131 to undergo elastic deformation through the spring 132 and retract into the second receiving groove 122.

[0091] During this process, due to different uneven conditions of the ground, for any stud assembly 1 where the anti-slip stud 131 encounters a relatively protruding ground condition, its spring 132 experiences relatively large elastic deformation, and the spring 132 retraction amount is also relatively large, thereby providing a height H3 between the first height H1 and the second height H2; For another arbitrary stud assembly 1 where the anti-slip stud 131 encounters a relatively recessed ground condition, its spring 132 experiences relatively small elastic deformation, and the spring 132 retraction amount is also relatively small, thereby providing a height H4 between the first height H1 and the second height H2. At this time, the adaptive condition of any two stud assemblies 1 on the shoe sole relative to the ground is manifested as heights H3 and H4 between the first height H1 and the second height H2 (where H4 is greater than H3), thereby completing adaptation to different uneven ground conditions (when walking on any different uneven grounds, any stud 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, where Hn satisfies H1≤Hn≤H1+H2);
According to different walking states (such as rearfoot-first ground contact or forefoot-first ground contact), the shock-absorbing effect is dynamically adjusted to reduce direct transmission of impact forces to the foot. The spring 132 continuously undergoes elastic deformation in response to center of gravity changes, effectively buffering the impact forces from the ground against the sole during walking, thereby greatly reducing the burden on joints such as knees and ankles during the walking process. In complex terrain such as snow layers, dirt roads, and rocky soil paths, the system similarly adjusts in real-time according to center of gravity changes to prevent slipping, thereby improving walking comfort and stability. Whether during starting, acceleration, deceleration, or turning in motion processes, reliable anti-slip protection is provided.

Embodiment 1

As shown in Figures 15 and 16, the midsole structure according to an embodiment of the present invention will be described in detail.

[0093] As another aspect of the present invention, there is provided a shoe sole further comprising a midsole 4, the midsole 4 having a first surface for contacting the instep and a second surface for contacting the anti-slip structure, wherein the second surface contacts the anti-slip structure according to any one of the aforementioned embodiments, wherein the second surface of the midsole 4 has at least one recess 411 adapted to the protrusion 213 for accommodating the protrusion 213.

[0094] Figure 17 is a top view of the midsole according to an embodiment of the present invention. As shown in Figure 17, the recess structure according to the embodiment of the present invention will be described in detail.

[0095] In order to provide sufficient space, the recess 411 is configured to provide space for accommodating the protrusion 213, wherein the depth of the space is positively correlated with the height of the protrusion 213 that accommodates the stud assembly 1. When the embedded stud assembly 1 has a greater height, the protrusion 213 extends to a correspondingly greater height, and the depth of the recess 411 increases accordingly. Simultaneously, the engagement between the recess 411 and the protrusion 213 increases the friction force of the contact surface, ensuring that the protrusion 213 is firmly embedded within the recess 411, thereby forming greater frictional resistance between the contact surfaces to prevent sliding.

[0096] To improve the durability of the shoe sole, the body 2 and the midsole 4 are connected using one of adhesive bonding, hot melting, or stitching, which ensures the bonding strength and stability between the body 2 and the midsole 4, while enhancing the durability of the shoe and production efficiency.

[0098] To ensure uniform force distribution across the shoe sole, the embedded stud assembly 1 is arranged in the anti-slip unit 21 in the forefoot region of the shoe sole using a fractal geometry arrangement centered on at least two stud assemblies 1, to provide the driving force required for greater grip in the forefoot area during movement (such as walking on muddy roads, mountain climbing, or walking on ice), and the embedded stud assembly 1 is arranged in the anti-slip unit 21 in the rearfoot region of the shoe sole using a fractal geometry arrangement centered on at least one stud assembly 1, to provide the stability required in the heel area during movement (such as walking on muddy roads, mountain climbing, or walking on ice), to disperse impact forces while conforming to the force distribution characteristics of human body movement, enabling the shoe sole to maintain good grip and stability in various movement scenarios.

[0099] To improve production efficiency, the body 2, midsole 4 and stud assembly 1 employ a layered processing method, wherein the body 2 and midsole 4 are processed first, followed by processing and assembly of the stud assembly 1 with the body 2, thereby enabling convenient and efficient manufacturing wherein each component can be individually processed with high precision, avoiding losses caused by integral processing, thus significantly improving product yield, reducing material waste, and achieving production cost reduction.

[Usage Method of Shoe Sole with Anti-slip Structure According to Embodiments of the Present Invention]

Usage Method A of Shoe Sole with Anti-slip Structure

[0103] When used on ice surfaces, the stud assembly 1 installed and configured on the outsole of the shoe sole enables strong anti-slip force to be achieved even on ice surfaces. Specifically, the anti-slip studs 131 of the stud assembly 1 make initial contact with the ground to provide a second anti-slip force, increasing the contact area with the ice surface. The stud assembly 1 can penetrate the ice surface to contact the underlying layer beneath the ice surface, thereby providing enhanced anti-slip force. Subsequently, the anti-slip unit 21 contacts the ice surface to provide a first anti-slip force, furnishing additional contact area with the ground for dual anti-slip protection. Through the configured spring 132, adaptive adjustment to ice surfaces with varying irregularities can be achieved to accommodate the ice surface, effectively improving the anti-slip performance on ice surfaces.

Subsequently, the anti-slip unit 21 contacts the rocky and dirt mountain paths to provide a first anti-slip force, offering additional contact area with the ground for dual anti-slip protection. The configured spring 132 enables adaptive response to varying uneven rock surfaces to accommodate rocky and dirt mountain paths, thereby effectively improving the anti-slip performance on rocky and dirt mountain terrain.

[0105] When walking or exercising on various types of uneven irregular surfaces, any stud assembly 1 adapts to the ground through spring 132, with the spring 132 continuously undergoing elastic deformation in response to changes in center of gravity, providing a height Hn between the first height H1 and second height H2, wherein Hn satisfies H1≤Hn≤H1+H2, effectively cushioning the impact force from the ground on the sole during walking, and adjusting in real-time according to changes in center of gravity and ground irregularities, thereby providing powerful anti-slip force and reliable motion protection.
