Description

Technical Field

[0001] This utility model discloses a novel knob shoe, belonging to the field of footwear technology. Background Technology

[0002] Screwdriver shoes are an innovative footwear design that replaces traditional shoelaces with a screwdriver system. Users can quickly tighten or loosen the laces by simply rotating the screwdriver on the shoe, achieving one-button adjustment of tightness. These shoes typically use high-strength micro-cables or elastic bands instead of traditional shoelaces, combined with an internal mechanical structure to ensure a secure fit, making them suitable for sports, daily commutes, and other scenarios.

[0003] The placement of the knob-type shoelace system directly affects the user experience. Side knobs prevent foot discomfort during exercise and distribute force evenly. Tongue knobs offer the most convenient operation, while heel knobs also adjust the tightness of the heel. Most existing heel knobs are directly sewn or glued to predetermined positions on the upper. Therefore, for ease of positioning and stability, it is necessary to create lacing holes, lacing channels, and knob installation openings in the upper fabric. These openings significantly weaken the overall strength of the upper fabric, and the edges of these openings are prone to material delamination or tearing under long-term friction, resulting in a short lifespan for such shoes. Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a new type of knob shoe to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a novel knob shoe, comprising a shoe body, an elastic cord, and a knob component. An outer hem is provided at the back of the shoe body, the outer hem covering the back of the shoe body. The outer hem is provided with a cord-threading protrusion for threading the elastic cord. The knob component is located on the rear side of the outer hem. The elastic cord extends from the cord-threading protrusion to the rear side of the outer hem and extends into the knob component.

[0006] Preferably, both ends of the outer port cover are provided with an extension portion extending along the shoe opening to the front of the shoe. The lacing protrusion extends from the front side of the extension portion to the rear side of the outer port cover. The lacing protrusion is provided with a lacing channel for threading an elastic cord. The rear side of the outer port cover is provided with a positioning groove. The knob is embedded in the positioning groove. The elastic cord extends from the lacing channel into the knob.

[0007] Preferably, a magnetic connector is provided between the knob and the outer port cover. The magnetic connector is embedded in the positioning groove and fixed to the outer port cover. The knob and the magnetic connector can be detached and connected.

[0008] Preferably, the magnetic connector includes a base and a plurality of first magnetic blocks and second magnetic blocks. The base is fixed to the outer port, the first magnetic blocks are surrounded and fixed on the base, the knob includes a mounting ring, the second magnetic blocks are surrounded and fixed on the mounting ring, and the positions of the first magnetic blocks and the second magnetic blocks are aligned.

[0009] Preferably, the base is provided with a connection release component for releasing the connection between the magnetic connector and the knob component, and the connection release component is slidably disposed on the base.

[0010] Preferably, the connection release member is provided with a pressing part, the pressing part covers the first magnetic block, and the base is provided with a sliding groove for the connection contact member to slide and avoid the first magnetic block.

[0011] Preferably, the mounting ring has a notch, and the connection release component has a pressing protrusion at the position corresponding to the notch.

[0012] Preferably, the connecting release member is provided with a limiting protrusion ring on the side facing the base, the limiting protrusion ring penetrates the base, and a limiting connector is fixed at one end of the limiting protrusion ring penetrating the base.

[0013] Preferably, the edge of the pressing part is inclined, and the top edge of the pressing part is aligned with the connecting surface of the first magnetic block and the second magnetic block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting an external heel counter at the back of the shoe, and setting a lanyard protrusion, lanyard channel, and positioning groove for installing the knob on the external heel counter, the traditional design of directly drilling holes in the upper material is avoided. This ensures the integrity and strength of the upper material. Moreover, because it is an external heel counter, it has sufficient support and durability for the knob and elastic cord in terms of hardness and strength, which greatly increases the service life of the shoe.

[0016] 2. The knob is connected to the outer cover by a magnetic connector. The ring-shaped layout of the magnetic structure ensures that the knob is evenly stressed when rotating and adjusting, avoiding the risk of falling off due to long-term friction caused by traditional adhesive or sewing methods, and increasing its service life.

[0017] 3. A detachable design is achieved by setting a connection release component between the knob and the magnetic connector. The components can be quickly separated by sliding pressure, making it simple and convenient to use, and thus facilitating the replacement or cleaning of the knob system when needed.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0027] A new type of knob shoe, such as Figure 1 , Figure 3As shown, the shoe includes a shoe body 1, an elastic cord 2, and a knob 3. An outer heel counter 4 is provided on the heel of the shoe body 1, and the outer heel counter 4 wraps around the heel of the shoe body 1. The outer heel counter 4 can be injection molded from TPU material with a Shore hardness of 90A-95A, so that it has high hardness while retaining a certain degree of flexibility, making the outer heel counter 4 wear-resistant and protective, without affecting the user's walking. The bottom of the outer heel counter 4 can be thickened and have an inwardly curved edge, so as to provide better support, positioning and protection while more closely wrapping the shoe upper.

[0028] like Figure 2 , Figure 3 As shown, both ends of the outer port 4 are provided with extensions 5 extending from the shoe opening to the front, and the extensions 5 are all attached to the surface of the shoe upper. Therefore, in addition to supporting and protecting the back of the shoe body 1, the outer port 4 also supports the entire shoe opening, preventing the shoe opening from collapsing during use, increasing the service life of the shoe, ensuring the wearer's wearing experience and maintaining the aesthetic appearance.

[0029] like Figure 2 , Figure 3 As shown, the extension 5 is provided with a rope-threading protrusion 6, which extends from the front of the extension 5 to the rear of the outer port 4. The rope-threading protrusion 6 has a rope-threading channel 7 for threading the elastic rope 2. A positioning groove 8 is provided on the rear of the outer port 4, and the knob 3 is embedded in the positioning groove 8. The rope-threading protrusion is located on both sides of the positioning groove 8. Figure 1 As shown, after the elastic cord 2 is threaded through the shoe upper, it extends from the rope channels 7 on both sides into the knob 3, and the elastic cord 2 can be adjusted through the knob 3.

[0030] Since the outer port cover 4 is an independent external component connected to the shoe upper, and the threading hole and threading channel 7 of the elastic cord 2 and the positioning groove 8 of the knob 3 are all located on the outer port cover 4, the shoe upper fabric of the shoe body 1 does not need to have any holes or openings, making it more complete and its strength is not compromised. This fundamentally solves the problem that the shoe upper fabric of this type of shoe is prone to tearing or wear after long-term use. Compared with the fabric, the outer port cover 4, which has a stronger hardness, has higher resistance to friction or pulling caused by the elastic cord 2 and the knob 3 during use, further increasing the service life of the shoe. Moreover, the outer port cover 4 provides protection on the outside, so the service life of the entire shoe upper fabric is longer.

[0031] like Figure 2 As shown, a magnetic connector 9 is provided between the knob 3 and the outer port cover 4. The magnetic connector 9 is embedded in the positioning groove 8 and fixed to the outer port cover 4. The knob 3 and the magnetic connector 9 can be detached and connected. The knob 3 can be firmly fixed on the outer port cover 4 by the magnetic attraction of the magnetic connector 9. The installation operation is simple and convenient.

[0032] like Figure 4 , Figure 5 As shown, the magnetic connector 9 includes a base 10 and several first magnetic blocks 11 and second magnetic blocks 12. The base 10 is fixed to the outer port 4 and can be glued to the inside of the positioning groove 8, and is completely embedded in the inside of the positioning groove 8. The first magnetic blocks 11 surround and are fixed to the base 10. The knob 3 includes a mounting ring 13, and the second magnetic blocks 12 surround and are fixed to the mounting ring 13. The two components are fixed by the magnetic attraction of the first magnetic blocks 11 and the second magnetic blocks 12. When the knob 3 is magnetically fixed, the mounting ring 13 is also embedded in the mounting ring 12. Within the positioning groove 8, its edge does not extend beyond the opening of the positioning groove 8. Therefore, in addition to magnetic attraction and stability, its lateral movement space is also restricted by the positioning groove 8, thereby further increasing the stability effect. The positions of the first magnetic block 11 and the second magnetic block 12 are aligned. In this embodiment, the first magnetic block 11 and the second magnetic block 12 use three strong magnetic button magnets to magnetically fix the sides and bottom respectively. The three-point fixation has sufficient stability. Depending on the model and requirements, different magnetic components can also be used, such as a semi-circular magnet or a multi-segment rectangular magnet arrangement.

[0033] like Figure 4 , Figure 5 As shown, the base 10 is provided with a connection release member 14 for releasing the connection between the magnetic connector 9 and the knob 3. The connection release member 14 is slidably disposed on the base 10. The connection release member 14 is provided with a pressing part 15, which covers the first magnetic block 11. The base 10 is provided with a sliding groove 16 for sliding of the connecting contact and avoiding the first magnetic block 11. The connection release member 14 is provided with a limiting protrusion ring 19 on the side facing the base 10. The limiting protrusion ring 19 penetrates the base 10. One end of the limiting protrusion ring 19 through the base 10 is fixed with a limiting connector 20. By sliding the connection release member 14, the two magnetic blocks can be pressed from the side, covering the first magnetic block 11 and separating the two magnetic blocks, thereby reducing the attraction force on the knob 3 and allowing the user to easily remove the knob 3 for cleaning or replacement.

[0034] Since the magnetic attraction between the two magnetic blocks on the side is much smaller than that on the end face, pressing them from the side can easily separate the two contact surfaces. The connecting release part 14 can be made of copper-zinc alloy, which has good hardness and wear resistance, and it will not be attracted by the magnetic blocks. Therefore, it can press and separate the two magnetic blocks well. The specific shape of the pressing part 15 can be adjusted according to the magnetic blocks. In this embodiment, the pressing part 15 is set as a protrusion on both sides and the bottom according to the three button magnets. It is only necessary to ensure that after sliding, the pressing part 15 covers the first magnetic block 11. The ring layout of the magnetic structure ensures that the knob 3 is subjected to uniform force when rotating and adjusting, avoiding the risk of falling off due to long-term friction caused by traditional adhesive or sewing methods, and increasing the service life.

[0035] like Figure 6 , Figure 7 As shown, the edge of the pressing part 15 is set to be inclined. The top edge of the pressing part 15 is aligned with the connecting surface of the first magnetic block 11 and the second magnetic block 12. The inclined edge of the pressing part 15 allows it to better press between the two magnetic blocks and push them apart. At the same time, the edges of the two magnetic blocks can also be set with an inclined angle to further increase the effect of pressing separation.

[0036] like Figure 4 As shown, the mounting ring 13 has a notch 17, and the connecting release piece 14 has a pressing protrusion 18 at the position corresponding to the notch 17. The user can press the pressing protrusion 18 on the outside of the notch 17, thereby causing the connecting release piece 14 to slide and separate the two magnetic blocks. The operation is simple and convenient.
