Description

Technical Field

[0001] This utility model relates to the field of footwear accessories technology, and in particular to a two-section full-length adjustable shoelace structure. Background Technology

[0002] As an important component of footwear, shoelaces play a crucial role in the wearing experience through their functionality and comfort. Traditional shoelace structures mostly use a continuous rope to be fixed to the shoe by crisscrossing, which has the advantage of being simple and easy to implement.

[0003] When putting on shoes, people need to thread shoelaces through the eyelets and then cross them until they reach the desired tightness. This method of tying is extremely common in daily life and has almost become the standard way to fix shoelaces. However, when adjusting the tightness of traditional shoelaces, it is necessary to move the shoelaces one by one through each eyelet. This method of adjustment is cumbersome, slow, and makes it difficult to precisely control the tightness. In addition, during the tying process, the tightness of traditional shoelaces is uniform or uncomfortable across the entire shoe surface. It cannot be adjusted differently according to the needs of the front and back of the instep. For example, if the front of the instep is too tight while the back is too loose, it will affect the wearing experience. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides the following solution. To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general description, nor is it intended to identify key / important components or to describe the scope of protection of these embodiments. Its sole purpose is to present some concepts in a simple form as a prelude to the detailed description that follows.

[0005] The present invention adopts the following technical solution:

[0006] A two-section, full-length adjustable shoelace structure is provided, comprising: webbing cords, a middle locking buckle, and a tail locking buckle. The webbing cords are interlaced and tied to the shoe upper to form several rows of tight-fitting straps.

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] like Figure 1-3 As shown, in some illustrative embodiments, a two-section full-length adjustable shoelace structure is provided, which can be independently adjusted according to the needs of different foot areas to meet personalized tightness requirements. Specifically, it includes: webbing cord 100, middle buckle 200, end buckle 300, lacing loop 400, and storage mechanism 500.

[0020] The webbing loops 400 are arranged in two rows, with two rows of loops 400 set on the shoe upper and located on both sides of the tongue. The loops 400 in each row are evenly spaced to ensure that the webbing cord 100 remains neat and stable when passing through. Preferably, a wider distance can be left at the location of the middle buckle 200 compared to other locations, thereby providing sufficient operating space for the middle buckle 200 and facilitating user adjustment. The webbing cord 100 crosses through the two rows of loops 400 and is tied to the shoe upper in an alternating manner to form several rows of tight-fitting straps on the shoe upper. Taking six rows of tight-fitting straps as an example, in this embodiment, the tight-fitting straps from the toe to the heel are sequentially labeled as the first row of tight-fitting straps 1, the second row of tight-fitting straps 2, the third row of tight-fitting straps 3, the fourth row of tight-fitting straps 4, the fifth row of tight-fitting straps 5, and the sixth row of tight-fitting straps 6.

[0021] The intersection of the webbing cords 100 is between two adjacent rows of tight-fitting straps, that is, the point where the webbing cords 100 cross and pass through the shoe upper. The middle buckle 200 is located at the intersection of the webbing cords between the second row of tight-fitting straps 2 and the third row of tight-fitting straps 3. This arrangement places the middle buckle 200 at the front end of the shoelace structure, close to the toe, making it easy for the user to adjust the tightness of the forefoot. After passing through the middle buckle 200, the webbing cords 100 continue to cross and extend backward to form subsequent tight-fitting straps, with the last row of tight-fitting straps being the one closest to the heel.

[0022] The tail buckle 300 is located at the webbing cord closure point on the back side of the last row of tight-fitting straps (the sixth row of tight-fitting straps 6 in this embodiment). The webbing cord closure point refers to the position of the two remaining ends of the webbing cords 100 after they have been crossed and tied from front to back. The tail buckle 300 ensures the stability of the rear of the shoelace structure and allows the user to adjust the tightness according to the comfort needs of the back of the foot.

[0023] Both the middle locking buckle 200 and the tail locking buckle 300 are provided with a lacing channel 231, and a locking gear 232 is provided within the lacing channel 231. The locking gear 232 is a structural component used to fix or release the webbing rope 100. The webbing rope 100 is adjusted by adjusting the position of the locking gear 232. When it is necessary to adjust the tightness of the shoelaces, the user can move the locking gear 232 to release the webbing rope 100. At this time, the user can drag the webbing rope 100 to make it move in the lacing loop 400, thereby adjusting the tightness of the shoelaces. Once a suitable tightness is found, the user can adjust the position of the locking gear 232 again to return it to its original position, fixing the webbing rope 100 in the lacing channel 231 and preventing it from moving further in the lacing loop 400, ensuring that the shoelaces remain in the set tension.

[0024] By introducing a mid-section buckle 200 and a rear-section buckle 300, the shoelaces are independently adjustable in sections, targeting the forefoot and heel areas of the foot respectively. This design allows for separate tension adjustments in each section to accommodate the different needs of different areas. Simultaneously, the quick tightening and loosening function of the buckles makes putting on and taking off the shoes more convenient. This two-section adjustable shoelace structure is particularly practical in sports such as trail running, especially when running downhill. Athletes can adjust the tightness of the forefoot by adjusting the tension of the front section of the shoelace, effectively stabilizing the forefoot and preventing it from lurching forward due to gravity, thus avoiding toe compression and impact, reducing bruising and black toe. This flexible adjustment mechanism not only improves comfort during exercise but also increases safety.

[0025] Both the middle section latch 200 and the tail section latch 300 include: a base plate 233, a spring 234, a locking gear 232, a push sliding cover 235, and a limiting block 236.

[0026] The sliding cover 235 is fastened to the base plate 233 and can slide back and forth on the base plate 233, driving the locking gear 232 to move together. The sliding cover 235 matches the outer contour shape of the base plate 233. A rope passage 231 is formed on the base plate 233, thereby forming a front passage wall 2331 in the front half of the base plate 233 and a rear passage wall 2332 in the rear half. The limiting block 236, the spring 234 and the locking gear 232 are arranged sequentially from front to back in the rope passage 231. The two ends of the webbing rope 100 pass through the latches from both sides of the limiting block 236 and exit from both sides of the locking gear 232.

[0027] A mounting groove 2361 is formed on the limiting block 236. The fixed end of the spring 234 is connected to the bottom of the mounting groove 2361, and the movable end of the spring 234 is connected to the locking gear 232. The width of the front half of the base plate 233 gradually increases from front to back, and the width of the rear half of the base plate 233 gradually decreases from front to back.

[0028] When the locking gear 232 is in the locked position, i.e., at the rear end of the rope channel 231, the locking gear 232 contacts the rear channel wall 2332 of the rope channel, thereby pressing the webbing 100 against the rear channel wall 2332 and fixing the webbing 100. When it is necessary to adjust the tightness, push the sliding cover 235 forward. At this time, the locking gear 232 moves forward together until it is in the released position. When the locking gear 232 is at a certain distance from the rear channel wall 2332 of the rope channel, the restriction on the webbing 100 is released. At this time, the user can drag the webbing 100 to make it move in the threading ring 400 until the appropriate tightness is found.

[0029] The rear end of the push-slide cover 235 has a limiting strip 2351 protruding towards the base plate 233, and the locking gear 232 is always abutting against the limiting strip 2351. When the locking gear 232 is in the locked position, the locking gear 232 is in contact with the limiting strip 2351. When the tightness needs to be adjusted, the push-slide cover 235 is pushed forward. At this time, the locking gear 232 moves forward together until it reaches the release position. The spring 234 is gradually compressed, but the locking gear 232 always remains in contact with the limiting strip 2351. After the adjustment is completed, the user releases the push-slide cover 235. The restoring force of the spring 234 pushes the limiting strip 2351, causing the push-slide cover 235 to return to its original position. At the same time, the locking gear 232 also returns to the locked position, re-fixing the webbing rope 100.

[0030] This embodiment provides a simple adjustment mechanism for adjusting the shoelace structure. Users can quickly adjust the tightness of the shoelaces with a simple push and pull action, without complicated operation steps. At the same time, it ensures the stability of the webbing cord 100 after adjustment. The use of spring 234 also enables the push slide cover 235 to automatically return to its original position after adjustment, increasing the convenience of use.

[0031] The sliding cover 235 includes a sliding cover body 2352. The sliding cover body 2352 has a front guide bar 2353 and a rear guide bar 2354 on the side facing the base plate 233, serving as a guide and limiting element. Both the front guide bar 2353 and the rear guide bar 2354 are embedded within the rope threading channel 231. When the locking gear 232 is in the locked position, the rear guide bar 2354 is in contact with the rear section wall 2332 of the rope threading channel, ensuring that the sliding cover body 2352 remains in the correct position, thereby securing the webbing rope 100. When the locking gear 232 is in the released position, the front guide bar 2353 is in contact with the front section wall 2331 of the rope threading channel. At this time, the sliding cover body 2352 moves forward, unlocking the securing of the webbing rope 100. The design of the front guide bar 2353 and the rear guide bar 2354 ensures that the push slide cover 235 moves precisely within the rope channel 231, enhances the stability of the push slide cover 235 in the locked and released positions, and improves the accuracy and reliability of adjustment.

[0032] The storage mechanism 500 includes: a column tube 510, a magnetic sheet 520, and a magnetic block 530.

[0033] A groove 540 is formed on the magnet 530 to match the magnetic piece 520. Both ends of the webbing 100 are located inside the column tube 510. The magnetic piece 520 is mounted on the column tube 510 to attract the magnet 530, which is mounted on the tail buckle 300. When the shoelace tightness does not need to be adjusted, the column tube 510 is fixed together by the magnetic action of the magnetic piece 520 and the magnet 530. In this way, the tail of the webbing 100 is fixed to the tail buckle 300, achieving effective storage.

[0034] During exercise or activity, the end of the webbing cord 100 is secured, preventing the shoelace ends from swinging freely and reducing potential interference with movement. The secured shoelaces will not loosen due to swinging, improving wearing safety, especially during strenuous exercise. Users simply need to bring the post tube 510 close to the magnet block 530, and the magnetic sheet 520 will automatically attract it, requiring no complicated steps and offering convenience and speed.
