Description

Technical Field

[0001] This utility model relates to the field of knob shoe technology, and in particular to a knob-type locking structure for shoe uppers and knob shoes. Background Technology

[0002] Slip-on shoes are a type of footwear that uses a slip-on lacing system instead of traditional shoelaces. By rotating the button, the tightness of the shoelaces can be quickly adjusted, eliminating the need for the cumbersome tying of traditional shoelaces. They are characterized by quick on and off, and a secure fit that won't come loose. They provide convenience for people with mobility impairments and also meet the needs of sports enthusiasts during high-intensity activities. They avoid the problems of tangling and loosening of traditional shoelaces, while also offering a stylish appearance and comfortable feel. They are now widely used in various styles of sports shoes, casual shoes, and more.

[0003] Currently, most screw-down shoes use a symmetrical threaded locking system. This design is primarily aimed at everyday wear by the general public, allowing for quick adjustment of tightness through a simple cycle of hooking and returning to the screw. However, for individuals with flat feet (also known as flatfoot deformity), this symmetrical threaded structure cannot effectively support the arch, resulting in continued collapse of the medial longitudinal arch and affecting ankle joint movement and athletic performance. Furthermore, for professional athletes who prioritize pedaling efficiency, this structure struggles to meet the stringent requirements for foot support and stability during high-intensity activities. In addition, due to the limited cable path and narrow locking area on the upper, the symmetrical threading method tends to concentrate locking force in a specific area of ​​the instep, compressing blood vessels and nerves, leading to numbness and other discomfort after prolonged wear, thus impacting both wearing experience and health.

[0004] Therefore, there is an urgent need to design a screw-on locking structure for the upper and a screw-on shoe that can effectively support the arch of the foot, with a larger locking area and stronger wrapping, precisely meeting the support needs of people with flat feet and the foot wrapping needs of professional athletes. At the same time, it can effectively distribute pressure concentrated in specific areas of the instep, avoiding compression of blood vessels and nerves in the instep due to concentrated pressure, greatly alleviating the problem of numbness in the feet caused by prolonged wear. Furthermore, this locking structure can adapt to different foot shapes and usage needs, greatly improving versatility and practicality, and further enhancing the user experience. Summary of the Invention

[0005] To overcome the problems existing in related technologies, this application provides a knob-type locking structure for the shoe upper and a knob-type shoe. This knob-type locking structure and shoe effectively support the arch of the foot, with a larger locking area and stronger wrapping, precisely meeting the support needs of people with flat feet and the foot wrapping needs of professional athletes. Simultaneously, it effectively disperses pressure concentrated in specific areas of the instep, avoiding compression of blood vessels and nerves due to concentrated force, greatly alleviating the problem of numbness in the feet caused by prolonged wear. Furthermore, this locking structure can adapt to different foot shapes and usage needs, greatly improving versatility and practicality, and further enhancing the user experience.

[0006] The first aspect of this application is to provide a shoe upper knob-type locking structure, including a knob fixing seat, a knob, a cable, a first guide buckle, a second guide buckle, a third guide buckle, and a fourth guide buckle; the knob fixing seat is fixed to the shoe upper and located at the center of the instep above the shoe upper; the knob is disposed on the top of the knob fixing seat; the first guide buckle and the second guide buckle are both disposed on the knob fixing seat and located on the same side of the knob fixing seat; the third guide buckle and the fourth guide buckle are respectively disposed at the longitudinal arch of the foot on the inner side of the shoe upper; the cable is respectively wound around the knob, the first guide buckle, the second guide buckle, the third guide buckle, and the fourth guide buckle.

[0007] In a preferred embodiment of this application, the line connecting the first guide buckle and the second guide buckle is parallel to the line connecting the third guide buckle and the fourth guide buckle, and the distance between the first guide buckle and the second guide buckle is less than the distance between the third guide buckle and the fourth guide buckle.

[0008] In a preferred embodiment of this application, the lines connecting the first guide buckle, the second guide buckle, the third guide buckle, and the fourth guide buckle form a trapezoid.

[0009] In a preferred embodiment of this application, after the cable extends from the knob, it is sequentially connected to the third guide buckle, the first guide buckle, the second guide buckle, and the fourth guide buckle.

[0010] In a preferred embodiment of this application, an adjustment component is further included; the adjustment component is respectively disposed at the third guide buckle and the fourth guide buckle, and is slidably connected to the third guide buckle and the fourth guide buckle respectively.

[0011] In a preferred embodiment of this application, the adjustment component includes a first slide rail and a second slide rail; both the first slide rail and the second slide rail are fixedly mounted on the shoe surface, and the extension direction of the first slide rail is consistent with the line connecting the first guide buckle and the third guide buckle, and the extension direction of the second slide rail is consistent with the line connecting the second guide buckle and the fourth guide buckle; the third guide buckle is slidably disposed within the first slide rail; and the fourth guide buckle is slidably disposed within the second slide rail.

[0012] In a preferred embodiment of this application, the adjustment component further includes several limiting parts; the several limiting parts are sequentially arranged along the extending directions of the first slide rail and the second slide rail, and are used to limit the positions of the third guide buckle and the fourth guide buckle.

[0013] In a preferred embodiment of this application, the limiting portion includes an integrally formed first protrusion and a second protrusion; the first protrusion is disposed on the outer side of the first slide rail and the second slide rail, and is used to drive the second protrusion to move outward through the first slide rail and the second slide rail under the action of external force; the second protrusion is disposed on the inner side of the first slide rail and the second slide rail; the third guide buckle and the fourth guide buckle are provided with grooves that are adapted to the second protrusion.

[0014] A second aspect of this application is to provide a knob shoe, including the aforementioned knob-type locking structure on the shoe upper.

[0015] The technical solution provided in this application has the following beneficial effects: The upper knob-type locking structure of this application includes a knob fixing seat, a knob, a cable, a first guide buckle, a second guide buckle, a third guide buckle, a fourth guide buckle, and an adjustment component. By setting the first guide buckle, the second guide buckle, the third guide buckle, and the fourth guide buckle, and placing the third guide buckle and the fourth guide buckle at the longitudinal arch of the foot on the inner side of the upper, the cable path can pass through the arch and form a quadrilateral with a larger area. Compared with the traditional symmetrical threading method, this setting not only effectively increases the coverage area enclosed by the cable, thereby increasing the locking area of ​​the upper and providing greater support to the arch, but also effectively disperses the pressure on specific areas of the instep, accurately meeting the support needs of people with flat feet and the foot wrapping needs of professional athletes. At the same time, by setting the cable routing method to a crisscross, reciprocating loop, compared with a simple quadrilateral connection method, this method can further increase the cable's support force on the arch.

[0016] By incorporating adjustment components, users can move the third and fourth guide buckles to their desired positions according to their foot shape, providing better support for the arch of the foot. This greatly improves practicality, versatility, and comfort, while also offering a simple structure and convenient and quick adjustment.

[0017] Compared to existing knob-type locking structures, the solution provided in this application effectively supports the arch of the foot, with a larger locking area on the upper and stronger wrapping, precisely meeting the support needs of people with flat feet and the foot wrapping needs of professional athletes. Simultaneously, it effectively disperses pressure concentrated in specific areas of the instep, preventing pressure on blood vessels and nerves in the instep due to concentrated force, greatly alleviating the problem of numbness in the feet caused by prolonged wear. Furthermore, this locking structure can adapt to different foot shapes and usage needs, greatly improving versatility and practicality, and further enhancing the user experience.

[0027] Preferred embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0030] Existing screw-on shoes with symmetrical threaded locking mechanisms cannot effectively support the arch of the foot for individuals with flat feet (also known as flatfoot deformities), resulting in continued collapse of the medial longitudinal arch and affecting ankle joint movement and athletic performance. Furthermore, this structure is insufficient for professional athletes who prioritize pedaling efficiency, as it fails to meet the stringent requirements for foot support and stability during high-intensity activities. In addition, due to the limited cable path and narrow locking area on the upper, the symmetrical threading method tends to concentrate locking force in a specific area of ​​the instep, compressing blood vessels and nerves, leading to numbness and other discomfort after prolonged wear, thus impacting both wearing experience and health.

[0031] To address the aforementioned issues, this application provides a knob-type locking structure for the shoe upper and a knob-type shoe. This structure effectively supports the arch of the foot, with a larger locking area and stronger wrapping effect, precisely meeting the support needs of people with flat feet and the foot wrapping needs of professional athletes. Simultaneously, it effectively disperses pressure concentrated in specific areas of the instep, preventing pressure on blood vessels and nerves due to concentrated force, greatly alleviating numbness in the feet caused by prolonged wear. Furthermore, this locking structure can adapt to different foot shapes and usage needs, significantly improving versatility and practicality, and further enhancing the user experience.

[0032] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings. Example 1

[0033] Please see Figures 1-5 The shoe upper knob-type locking structure of this application includes a knob fixing seat 1, a knob 2, a cable 3, a first guide buckle 4, a second guide buckle 5, a third guide buckle 6, and a fourth guide buckle 7. The knob fixing seat 1 is fixed to the shoe upper and is located in the middle of the instep. The knob 2 is disposed on the top of the knob fixing seat 1 and is connected to the knob fixing seat 1 via a rotating shaft. The first guide buckle 4 and the second guide buckle 5 are both disposed on the knob fixing seat 1 and are located on the same side of the knob fixing seat 1. The third guide buckle 6 and the fourth guide buckle 7 are respectively disposed at the longitudinal arch of the foot on the inner side of the shoe upper. The cable 3 is respectively wound around the knob 2, the first guide buckle 4, the second guide buckle 5, the third guide buckle 6, and the fourth guide buckle 7.

[0034] Specifically, the lines connecting the first guide buckle 4, the second guide buckle 5, the third guide buckle 6, and the fourth guide buckle 7 form a quadrilateral, which can be an irregular quadrilateral or a parallelogram. The cable 3 extends from the knob 2 and connects sequentially to the third guide buckle 6, the first guide buckle 4, the second guide buckle 5, and the fourth guide buckle 7, as shown below. Figure 1 As shown, after extending from the knob 2, the cable 3 first winds around the inside-bottom-outside of the third guide buckle 6 to the outside of the first guide buckle 4, then extends from the top of the first guide buckle 4 to the top of the second guide buckle 5, then extends from the outside of the second guide buckle 5 to the outside of the fourth guide buckle 7, and then winds around from the bottom of the fourth guide buckle 7 to the inside, extending to the knob 2. By setting the cable 3 to a crisscross, reciprocating loop, compared to a simple quadrilateral connection, this cable routing method can further increase the support of the cable 3 for the arch of the foot and effectively distribute the pressure on the instep.

[0035] Preferably, the lines connecting the first guide buckle 4, the second guide buckle 5, the third guide buckle 6, and the fourth guide buckle 7 form a trapezoid, that is, the line connecting the first guide buckle 4 and the second guide buckle 5 is parallel to the line connecting the third guide buckle 6 and the fourth guide buckle 7, which makes the force distribution at the arch of the foot more even. To further increase the support area, the distance between the first guide buckle 4 and the second guide buckle 5 is smaller than the distance between the third guide buckle 6 and the fourth guide buckle 7, so that the area of ​​the trapezoid can be maximized. More preferably, the lines connecting the first guide buckle 4, the second guide buckle 5, the third guide buckle 6, and the fourth guide buckle 7 form an isosceles trapezoid to evenly distribute the pressure on the instep.

[0036] Furthermore, in order to adapt to different foot shapes, the upper knob-type locking structure also includes an adjustment component 8, which is respectively disposed at the third guide buckle 6 and the fourth guide buckle 7, and is slidably connected to the third guide buckle 6 and the fourth guide buckle 7, for adjusting the position of the third guide buckle 6 and the fourth guide buckle 7.

[0037] Specifically, the adjustment component 8 includes a first slide rail 81 and a second slide rail 82, both of which are fixed to the shoe surface. For example, the first slide rail 81 and the second slide rail 82 are made of nylon and are fixed to the shoe surface by stitching. The extension direction of the first slide rail 81 is consistent with the line connecting the first guide buckle 4 and the third guide buckle 6, and the extension direction of the second slide rail 82 is consistent with the line connecting the second guide buckle 5 and the fourth guide buckle 7. The third guide buckle 6 is slidably disposed within the first slide rail 81, and the fourth guide buckle 7 is slidably disposed within the second slide rail 82. When the user needs to move the position of the third guide buckle 6 and / or the fourth guide buckle 7, simply moving the third guide buckle 6 and / or the fourth guide buckle 7 will allow them to move along the extension directions of the first slide rail 81 and / or the second slide rail 82.

[0038] Furthermore, to facilitate fixing the positions of the third guide buckle 6 and the fourth guide buckle 7, the adjusting assembly 8 also includes several limiting parts 83. These limiting parts 83 are sequentially arranged along the extending directions of the first slide rail 81 and the second slide rail 82, and are used to limit the positions of the third guide buckle 6 and the fourth guide buckle 7. Specifically, the limiting parts 83 are made of nylon and include an integrally formed first protrusion 831 and a second protrusion 832. The first protrusion 831 is located on the outer side of the first slide rail 81 and the second slide rail 82, and is used to drive the second protrusion 832 to move outward through the first slide rail 81 and the second slide rail 82 under the action of external force. The second protrusion 832 is located on the inner side of the first slide rail 81 and the second slide rail 82. The third guide buckle 6 and the fourth guide buckle 7 are provided with grooves that match the second protrusion 832. For example, a strip-shaped through hole is provided on one side of the slide rail, and the limiting part 83 further includes a connecting strip 833. One end of the connecting strip 833 is integrally connected to the wall of the strip-shaped through hole, and the other end is integrally connected to the first protrusion 831 and the second protrusion 832. The top and bottom ends of the connecting strip, the first protrusion 831 and the second protrusion 832 are respectively provided with gaps between them and the wall of the strip-shaped through hole to reduce the friction force experienced by the first protrusion 831 and the second protrusion 832 when they move.

[0039] Working principle:

[0040] When a user puts on the screw-on shoe, rotating the screw 2 causes it to rotate clockwise relative to the screw fixing seat 1. The ratchet inside the screw fixing seat 1 locks the cable 3, causing the cable 3 to tighten continuously. At this time, the cable 3 wrapped around the first guide buckle 4, the second guide buckle 5, the third guide buckle 6, and the fourth guide buckle 7 also tightens continuously until it is close to the shoe surface, providing inward pressure to the shoe surface at the longitudinal arch of the foot. This allows the shoe surface at this point to provide more support to the arch of the foot. At the same time, because the first guide buckle 4, the second guide buckle 5, the third guide buckle 6, and the fourth guide buckle 7 are distributed, the area covered by the cable 3 is larger, the shoe surface locking force is greater, and the support force is also greater. Correspondingly, the pressure it exerts on the shoe surface is also distributed in multiple places, thereby dispersing the pressure concentrated in a specific area of ​​the instep. When the user needs to adjust the position of the third guide buckle 6 and / or the fourth guide buckle 7, they only need to pinch the first protrusion 831 and pull it outward. This causes one end of the connecting strip 833 and the second protrusion 832 to move outward through the strip-shaped through hole, with the other end of the connecting strip 833 as the fulcrum. This allows the second protrusion 832 to disengage from the slot of the third guide buckle 6 and / or the fourth guide buckle 7. Then, by moving the third guide buckle 6 and / or the fourth guide buckle 7, they can move along the extension direction of the first slide rail 81 and / or the second slide rail 82 until they reach the desired position. Then, the guide buckle presses the second protrusion 832, causing the second protrusion 832 to move outward until the slot is aligned with the protrusion. The rebound force of the second protrusion 832 then locks it in the slot, thereby achieving the desired position of the third guide buckle 6 and / or the fourth guide buckle 7.

[0041] In this first embodiment, the shoe upper knob-type locking structure of this application includes a knob fixing seat, a knob, a cable, a first guide buckle, a second guide buckle, a third guide buckle, a fourth guide buckle, and an adjustment component. By setting the first, second, third, and fourth guide buckles, and placing the third and fourth guide buckles at the longitudinal arch of the foot on the inner side of the shoe upper, the cable path can pass through the arch and form a larger quadrilateral. Compared with the traditional symmetrical threading method, this setting not only effectively increases the coverage area enclosed by the cable, thereby increasing the locking area of ​​the shoe upper and providing greater support to the arch, but also effectively disperses the pressure on specific areas of the instep, precisely meeting the support needs of people with flat feet and the foot wrapping needs of professional athletes. At the same time, by setting the cable routing method to a crisscross, reciprocating loop, compared with a simple quadrilateral connection method, this method can further increase the cable's support force on the arch. By incorporating adjustable components, users can move the third and fourth guide buckles to their desired positions according to their foot shape, providing better arch support and significantly improving practicality, versatility, and comfort. The structure is simple and adjustment is quick and easy. Compared to existing knob-type locking structures, the solution provided in this application effectively supports the arch, has a larger locking area on the upper, and offers stronger wrapping, precisely meeting the support needs of people with flat feet and the foot wrapping needs of professional athletes. Simultaneously, it effectively disperses pressure concentrated in specific areas of the instep, preventing pressure on blood vessels and nerves in the instep and greatly alleviating numbness caused by prolonged wear. Furthermore, this locking structure can adapt to different foot shapes and usage needs, greatly improving versatility and practicality, and further enhancing the user experience. Example 2
