Description

Technical Field

[0001] The utility model relates to the field of shoes, in particular to a quick-entry shoe. Background Art

[0002] In the field of footwear, designers and consumers have always pursued the convenience and comfort of wearing. However, traditional shoe designs usually rely on fastening methods such as shoelaces, Velcro or zippers to ensure the fit between the shoe and the foot. Although these methods are effective, they are not convenient enough in scenarios where quick on and off is required, such as athletes changing equipment, daily commuting or emergencies. In addition, these fastening methods may affect the aesthetics of the shoe upper and the overall wearing experience. For existing footwear, the recovery performance in the heel area is insufficient, that is, after the foot is inserted, the shoe heel cannot effectively return to its initial state, which affects the comfort of wearing the shoes and the fit of the shoes. Summary of the Utility Model

[0036] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present utility model in combination with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts all belong to the scope of protection of the present utility model. In addition, all the connection / linkage relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present utility model can be combined with each other without conflict.

[0037] The quick - entry shoe of the present utility model can be applicable to various types of shoes, including but not limited to sports shoes, casual shoes, dress shoes, high - heels, running shoes, hiking shoes, work shoes, sandals, slippers, boots and canvas shoes, etc. By integrating the bendable component 3, the function of quick putting on and taking off can be realized.

[0038] Refer toFigure 1 , the quick-entry shoe of the present utility model includes a sole 1 and a flexible member 3 mounted on the sole 1. The sole 1 is used to provide bottom support when worn. Refer to Figure 1-4 , the flexible member 3 has a flexing portion 31 and a fixing portion 41. The flexing portion 31 is fixed to both sides of the sole 1 near the heel end. The flexing portion 31 extends obliquely towards the shoe heel 2. The flexing portion 31 is fixed to both sides of the sole 1 near the heel end, providing good structural stability and helping to prevent the shoes from deforming during wearing; the fixing portion 41 is arranged along the circumference of the shoe mouth and is fixedly connected to the flexing portion 31, enhancing the support of the shoe heel 2 and helping to maintain the shape and structure of the shoes, providing a stable wearing experience. The flexible member 3 has a flexed state under a predetermined pressure and automatically returns to the extended state after removing the compressive force; wherein, in the flexed state, the flexible member 3 deforms, allowing the heel to be more easily inserted into the shoe, reducing the resistance when putting on the shoes, making it more convenient and quick to put on and take off, and providing a stable wearing experience; the flexible member 3 supports the fixing portion 41 to return to the extended state through the flexing portion 31 to support the shoe heel 2 and maintain the shape and structure of the shoes. The flexible member 3 provides good structural stability and helps to prevent the shoes from deforming during wearing.

[0039] In some embodiments, refer to Figure 6 , the flexible member 3 is fixedly connected to the inner wall surface of the heel. It can be understood that this can ensure the stability of the flexible member 3 during movement and prevent the heel from sliding or shifting inside the shoe. The full contact and fixed manner between the flexible member 3 and the inner wall surface of the shoe heel 2 provides uniform support, helps to disperse the pressure on the heel, is conducive to the flexible member 3 supporting the shoe heel 2, and can enter the extended state from the flexed state, enhancing the experience of quickly putting on shoes.

[0040] In some embodiments, the flexible member 3 is embedded in the composite sandwich structure 21 of the heel flank. The sandwich structure is used to accommodate and protect the flexible member 3. It can be understood that the sandwich structure provides comprehensive protection for the flexible member 3, protecting it from external friction, impact and environmental factors. In addition, it also avoids direct contact with the foot, reduces discomfort or injury that may be caused by friction, and at the same time allows better buffering and adaptation to the shape of the foot.

[0041] In some embodiments, refer to Figure 4 , 6, the fixing part 41 is designed in a U-shaped structure and is arranged along the circumference of the shoe mouth. Its opening faces the toe direction. That is to say, the fixing part 41 can make the shoe mouth have a fixing structure, so that the shoe mouth always remains open when putting on and taking off. In addition, the opening direction of the fixing part 41 corresponds to the direction of the shoelace and is used in conjunction with the shoelace fastening system to adapt to different foot shapes, thereby enhancing the overall functionality while improving the wearing comfort.

[0042] In some embodiments, the flexing part 31 and the fixing part 41 are connected by means of stitching, hot melting, embedding combination, etc., preferably by bonding.

[0043] In some embodiments, referring to Figure 1 , a receiving groove 3112 is provided on the flexing part 31 at the connection with the fixing part, and the fixing part is arranged in the receiving groove 3112.

[0044] It should be noted that the shape of the fixing part can be set according to the specific shape of the shoe mouth to ensure that it can closely fit the shoe mouth, thereby providing more stable support and a comfortable wearing experience. The fixing part can be designed in a ring shape, a U shape or other forms suitable for the shape of the shoe mouth. At the same time, elastic materials or adjustment devices can be used to adapt to the foot shapes and needs of different users. In addition, the fixing part can also be reliably connected to the shoe body by stitching, bonding or other fixing methods, thereby enhancing the overall firmness and durability of the shoe.

[0045] Furthermore, referring to Figure 1-3 , the flexing part 31 has a plurality of flexing segments, and the plurality of flexing segments are in an S shape. The S-shaped flexing segments can provide better elastic recovery performance, similar to the function of a spring, so that the flexing part 31 can quickly and effectively return to the initial state after the pressure on the heel is removed. And the plurality of flexing segments can more effectively disperse the pressure exerted by the heel, reduce the concentrated stress on a specific area, thereby reducing the risk of wear and damage.

[0046] Furthermore, referring to Figure 1, the flexion and extension part 31 includes a first flexion and extension section 311 and a second flexion and extension section 312. One end of the first flexion and extension section 311 is connected to the sole 1, and the other end faces the direction of the shoe heel 2 and is connected to one end of the second flexion and extension section 312. The other end of the second flexion and extension section 312 faces the direction of the shoe toe and is connected to the fixing part 41. It can be understood that the first flexion and extension section 311 and the second flexion and extension section 312 are connected at an angle to better disperse the force and reduce the pressure concentration on a single part, thereby improving the wearing comfort and the durability of the shoes. In some embodiments, the first flexion and extension section 311 and the second flexion and extension section 312 form a continuous single structure through an integral molding process. Through the integral molding design, the production process is simplified, the manufacturing time is shortened, and the production efficiency is improved. Moreover, the entire flexion and extension part 31 uses the same material, which can ensure that its physical properties such as elasticity, flexibility, and durability in different regions are consistent, improving the overall performance.

[0047] Furthermore, referring to Figure 2 , the first flexion and extension section 311 extends longitudinally along the direction from the sole 1 to the shoe heel 2, and the width of its cross-section gradually decreases from the end connected to the sole 1 to the other end, forming a gradually tapering profile to achieve a design that fits the heel curve better. It can be understood that the wider part below the first flexion and extension section 311 provides greater support force. As the width gradually decreases upwards, the support force decreases linearly, forming a progressive support effect. Moreover, it enables the first flexion and extension section 311 to generate more uniform and controlled deformation when subjected to pressure, avoiding local excessive bending or folding.

[0048] In some embodiments, referring to Figure 1-3 , the end of the first flexion and extension section away from the sole has a curved surface structure 3111 that bends towards the inside of the shoe; one end of the second flexion and extension section close to the first flexion and extension section extends in the direction of the shoe toe and has a support end 3121 that bends towards the inside of the shoe. The support end 3121 cooperates with the fixing part to support the shoe mouth. The curved surface structure 3111 and the support end 3121 fit the shape of the shoe last, which can support and fix the shoe last, so that a space for the foot to accommodate is formed inside the shoe.

[0049] In some embodiments, the flexion and extension part 31 and the fixing part 41 are made of the same material, and the density of the flexion and extension part 31 is lower than the density of the fixing part 41. It can be understood that when the material types are the same, a material with a greater density often means greater hardness. The greater hardness of the fixing part 41 can better maintain the stability of the shoe mouth structure and provide the necessary support force; in contrast, the flexion and extension part 31 has a lower density but better elasticity, enabling it to easily adapt to the shape of the heel when putting on and taking off the shoes, that is, it can quickly return to its original state after being pressed, thus providing a smoother wearing and taking off experience.

[0050] In some embodiments, the flexion and extension part 31 and the fixing part 41 are made of different materials. By selecting different polymer elastic materials, it can meet the requirement that the flexion and extension part 31 has higher elasticity, while the fixing part 41 has greater hardness.

[0051] In some preferred embodiments, the density of the fixing part 41 is 2-3 times that of the flexion and extension part 31. The performance difference between the fixing part 41 and the flexion and extension part 31 provides a balance point, which can ensure that the fixing part 41 has sufficient hardness and stability without sacrificing the flexibility and elasticity of the flexion and extension part 31.

[0052] The above is a specific description of the preferred embodiments of the present invention. However, the present invention is not limited to the above embodiments. Those skilled in the art can make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
