Description

Technical Field

[0001] This utility model relates to the field of clothing design technology, and more specifically, to an anti-loosening cord. Furthermore, this utility model also relates to a shoe incorporating the aforementioned anti-loosening cord. Background Technology

[0002] The problem of loose shoelaces is a long-standing and unresolved technical pain point in footwear products. Its essence lies in the fact that traditional shoelaces, in terms of both material properties and structural design, fail to effectively address the core challenge of "frictional self-locking stability under dynamic environments." During actual use, such as walking, running, and jumping, shoelace systems must continuously withstand periodic dynamic loads from multiple directions. Traditional anti-loosening solutions are often based on static or quasi-static assumptions, making it difficult to maintain effective restraint under prolonged dynamic stress.

[0003] Specifically, the existing mainstream technical approaches have the following obvious drawbacks:

[0004] Firstly, there is insufficient dynamic stability. Most current anti-loosening technologies still rely on increasing the surface friction coefficient of materials as the primary anti-slip method, such as using specific textures or high-friction polymers. However, in real-world sports scenarios, continuous alternating stress causes micro-displacements between the shoelaces and eyelets, as well as at the knots themselves, resulting in a shift from relatively stable "static friction" to unstable "sliding friction." This process is particularly affected by the surface smoothness of the shoelace material; with increased use, the friction interface gradually becomes smoother due to wear. Furthermore, changes in environmental temperature and humidity alter the surface properties of the material, further accelerating the decay of the friction coefficient, ultimately causing traditional anti-loosening measures to gradually fail in dynamic environments, and the risk of loosening remains.

[0005] Secondly, durability is poor. Some improvements enhance friction by coating the shoelaces with silicone, rubber, or other polymer coatings. While these designs provide good anti-slip performance initially, the limited adhesion between the coating and the substrate leads to problems such as localized peeling and cracking after repeated bending, friction, and environmental aging. Actual tests show that most coated anti-slip shoelaces exhibit significant wear on their surface coating after 1-2 months of use, resulting in a sharp drop in anti-slip performance and failing to meet users' basic requirements for product durability.

[0006] Furthermore, existing technologies still lack systematic research on the force patterns of shoelaces under complex motion conditions, and lack a deep understanding of the coupling mechanism of "motion-stress-friction". As a result, anti-loosening designs often remain at the level of empirical improvements and have failed to form a fundamental solution based on mechanical principles.

[0007] In conclusion, how to solve the problem of loose shoelaces is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] In view of this, the purpose of this utility model is to provide an anti-loosening rope, wherein the surface of the core is provided with annular protrusions and a rope body section, which can form an interlocking anti-slip texture to prevent shoelaces from loosening.

[0009] Another objective of this invention is to provide a shoe that includes the aforementioned anti-loosening strap.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] An anti-loosening rope, comprising:

[0012] The wire core has a strip-shaped structure;

[0013] An annular protrusion is spirally disposed on the surface of the wire core along the length direction of the wire core;

[0014] The main rope section is spirally disposed on the surface of the core along the length direction of the core. The main rope section and the annular protrusion section are intersected and the thickness of the main rope section along the radial direction of the core is less than the thickness of the annular protrusion section along the radial direction of the core.

[0015] Preferably, both the annular protrusion section and the main rope section include several strands of yarn, and the number of yarns in the annular protrusion section is greater than the number of yarns in the main rope section.

[0017] Preferably, the annular protrusion segment includes a fine texture segment, which is correspondingly arranged with the white dot segment and has the same smoothness.

[0018] Preferably, the annular protrusion further includes a coarse texture segment, the roughness of which differs from that of the fine texture segment.

[0019] Preferably, the coarse texture segment covers a portion of the gray dot segment.

[0020] Preferably, the height difference between the annular protrusion and the main rope section in the radial direction of the core is between 0.2 mm and 1 mm.

[0021] Preferably, the yarn is a composite polymer structure with a smooth surface.

[0022] Preferably, the cross-section of the wire core is circular or elliptical.

[0023] A shoe includes a tethering strap, wherein the tethering strap is any of the tethering straps described above.

[0024] This utility model provides an anti-loosening rope with a strip-shaped core. The core has annular protrusions and a main rope section on its surface. Both the protrusions and the main rope section are spirally arranged along the length of the core and located on its surface. The protrusions and the main rope section are intersecting. Furthermore, there is a height difference between the protrusions and the main rope section in the radial direction of the core. When tightened with the rope, this creates an interlocking, anti-slip texture, significantly increasing friction and resistance, thus preventing the rope from loosening. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The core of this utility model is to provide an anti-loosening rope, wherein the annular protrusions on the surface of the rope and the main body of the rope can form an interlocking anti-slip texture to prevent the rope from loosening.

[0032] Another core aspect of this invention is to provide a shoe that includes the aforementioned anti-loosening rope strap.

[0033] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description. It is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0034] The present application provides an anti-loosening rope, comprising: a core wire 1, an annular protrusion section 2, and a rope body section 3;

[0035] Among them, core 1 has a strip-shaped structure;

[0036] The annular protrusion 2 is spirally disposed on the surface of the core 1 along the length direction of the core 1;

[0037] The main rope segment 3 is spirally arranged on the surface of the core 1 along the length direction of the core 1. The main rope segment 3 and the annular protrusion segment 2 are arranged intersectingly, and the thickness of the main rope segment 3 along the radial direction of the core 1 is less than the thickness of the annular protrusion segment 2 along the radial direction of the core 1.

[0038] For details, please refer to the appendix. Figure 2 Both the annular protrusion 2 and the rope body 3 are located on the outer surface of the core 1 and extend spirally along the length of the core 1 to wrap around the entire core 1. The annular protrusion 2 and the rope body 3 are opposite spirals to achieve their cross arrangement. In the radial direction of the core 1, the thickness of the rope body 3 is less than the thickness of the annular protrusion 2, so that the annular protrusion 2 and the rope body 3 can form a concave-convex structure in the axial direction of the core 1. Traditional unidirectional spiral shoelaces may "rotate and loosen" along the spiral direction when subjected to vibration or tension in a specific direction. However, in this application, when two opposite spiral protrusions exist simultaneously, the loosening tendency generated by one spiral will be immediately prevented by the other opposite spiral. They restrain each other, forming an inherent mechanical balance, which greatly enhances the stability of the system, making it extremely difficult for the shoelaces to come loose on their own and preventing the rope from loosening. It is very suitable for sports such as running, mountaineering, basketball, and football that require frequent changes of direction, sudden stops, and violent vibrations. The two protrusions mean more contact points with the shoelace holes, significantly increasing the total friction. This provides stronger tightening force, as traditional single-point force or unidirectional protrusions can lead to excessive localized pressure on the shoelaces. The reverse spiral design distributes the tension force across multiple contact points of the two spirals, avoiding stress concentration. This not only makes the shoelaces more secure but also improves comfort, preventing the shoelaces from leaving deep indentations on the instep. Due to the high and stable friction, the shoelaces will not slip under slight force. This allows users to finely adjust the tightness of the shoelaces to find the most suitable tightness for their foot shape. Once adjusted, it remains firmly in place. In short, when tightening the laces, it creates an interlocking, anti-slip texture to increase friction and resistance.

[0039] Based on the above embodiments, both the annular protrusion section 2 and the rope body section 3 include several strands of yarn, and the number of yarns in the annular protrusion section 2 is greater than the number of yarns in the rope body section 3.

[0040] Specifically, the difference between the annular raised section 2 and the main rope section 3 lies in the difference in the number of yarn plies. Different numbers of yarn plies are used in different areas to achieve the distinction between the annular raised section 2 and the main rope section 3. It does not rely on the protrusion of the yarn itself, but rather on the change in the weaving structure caused by the difference in the number of plies. In other words, the annular raised section 2 is woven with multiple yarns. Due to the large number of yarn plies, the interlacing density and structural shape of the yarn change during the weaving process, thus forming the annular raised section 2. The main rope section 3 uses relatively fewer yarns during the weaving process. Therefore, the protrusion of the annular raised section 2 is more obvious than that of the main rope section 3.

[0041] Based on the above embodiment, the main rope segment 3 includes a white dot segment 301 and a gray dot segment 302, which are arranged intersectingly.

[0042] Specifically, the main rope section 3 is woven with fewer yarn threads than the annular raised section 2, and the number of yarn strands is relatively small. It is mainly formed by the cross weaving of white dot section 301 and gray dot section 302 to form the basic main structure of the rope.

[0043] Based on the above embodiment, the annular protrusion segment 2 includes a fine texture segment 201, which is correspondingly set with the white dot segment 301 and has the same smoothness.

[0044] Specifically, the white dot segment 301 on the main rope segment 3 and the fine texture segment 201 on the annular protrusion segment 2 are woven from the same yarn to form the fine texture segment 201. Therefore, the fine texture segment 201 and the white dot segment 301 are correspondingly set and have the same smoothness.

[0045] Based on the above embodiments, the annular protrusion 2 also includes a coarse texture segment 202, which has a different roughness than the fine texture segment 201.

[0046] Specifically, the coarse texture section 202 is the base part of the annular protrusion section 2, which is the multi-strand yarn structure used in the aforementioned annular protrusion. Therefore, the surface roughness of the coarse texture section 202 is different from that of the fine texture section 201, which can increase the surface roughness.

[0047] Based on the above embodiment, the coarse texture segment 202 is set to cover part of the gray dot segment 302.

[0048] Specifically, after the gray dot segment 302 and the white dot segment 301 are spirally interwoven, the gray dot segment 302 is hidden under the coarse texture segment 202. Therefore, the annular raised segment 2 can display two textures of different thicknesses, namely the fine texture segment 201 and the coarse texture segment 202, forming a circular raised dot of different thicknesses, which increases the surface roughness.

[0049] In some embodiments, the height difference between the annular protrusion 2 and the rope body section 3 in the radial direction of the core 1 ranges from 0.2 mm to 1 mm.

[0050] Specifically, the rope body section 3 and the annular protrusion section 2 have a certain height difference at their highest points in the radial direction of the core 1. The height difference ranges from 0.2mm to 1.0mm to form a concave structure that can accommodate the knot crossing part, enhance the locking effect, and ensure effective engagement with the shoelace eye and the knot crossing point. More specifically, the annular protrusion section 2, as the main locking part, will first contact and engage with the shoelace eye when the shoelace is in a loose state or in the initial stage of tightening, providing strong initial friction and responsible for the main "tightening" action. The rope body section 3 plays a micro-locking and triggering role. When the shoelace is fully tightened, the high protrusion section may deform under strong tension or be pressed more tightly into the gap of the shoelace eye, and the low protrusion section begins to contact and play its role. It acts like a secondary safety measure, preventing minor slippage after the high protrusion reaches its limit. The main rope section 3 and the loop protrusion section 2 work together to ensure that the friction of the shoelace increases in a step-like or gradual manner as it goes from "tight" to "very tight," rather than remaining constant. This creates a dynamic, adaptive locking system where the locking effect increases with the tension.

[0051] In some embodiments, the yarn is a smooth-surfaced composite polymer structure.

[0052] Specifically, composite polymers refer to high-performance multiphase materials made by adding one or more fillers or reinforcing materials to a polymer (plastics, rubber, etc.) matrix through composite technology. The core idea is to "compensate for the weaknesses of each component," combining the advantages of each component to achieve superior performance that a single material cannot achieve. It's important to note that it's not a single chemical substance, but rather the product of a broad class of materials design concepts. By combining flexible polymers with rigid reinforcing materials, it creates advanced materials with performance far exceeding that of their individual components. It is a prominent representative of modern materials science and engineering and one of the key materials driving high-tech development and industrial upgrading.

[0053] Based on the above embodiments, the cross-section of the wire core 1 is circular or elliptical.

[0054] Specifically, core 1 is woven from specially treated yarn with a circular or flat cross-section, increasing the contact area with the shoelace eyelets while ensuring flexibility. Depending on the machine model, the number of yarns and weaving density are set accordingly. For round ropes, the diameter is controlled between 2 and 10 mm, and the number of yarns is controlled between 2 and 10. For flat ropes, the width is controlled between 4 and 25 mm, and the number of yarns is controlled between 2 and 8, improving structural stability and abrasion resistance. Figure 1 The cross-sectional view of the anti-loosening shoelace shown is circular, with a diameter between 4.5 and 5.0 mm.

[0055] It should be noted that existing ropes can only achieve 9N in the anti-loosening test, while the anti-loosening rope provided in this application achieves anti-loosening of shoelaces through surface texture design and special post-treatment yarn, while optimizing the process to control costs, and the anti-loosening test reaches more than 20N.

[0056] In addition to the aforementioned anti-loosening straps, this utility model also provides a shoe that includes the anti-loosening straps disclosed in the above embodiments. For the structure of other parts of the shoe, please refer to the prior art, which will not be repeated here.

[0057] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0058] The above provides a detailed description of the anti-loosening rope and shoes provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
