Description

Technical Field

[0001] This utility model relates to the field of footwear technology, specifically to an easy-to-wear and easy-to-take-off stable shoe heel counter. Background Technology

[0002] The heel counter, as part of the shoe body, primarily provides support and wrapping for the heel, playing a crucial role in improving the user's wearing experience. However, existing heel counters have several problems:

[0003] Some designs are inconvenient to put on and take off. For example, some shoes have complex heel counter structures, requiring users to spend a lot of time and effort to accurately put their heels on. For instance, the invention patent with publication number CN 114601230 A discloses an easy-to-wear shoe that achieves ease of wear through a bending section and supporting elastic elements, but it does not effectively solve the problem of rubbing caused by the contact between the waist and the back ankle.

[0004] While some shoe heel counters offer a degree of stability, they tend to collapse after prolonged use, making it difficult to maintain that stability. For example, the utility model patent with publication number CN 217524104 U discloses a shoe heel counter structure that enhances its anti-bending performance by placing a support within the cavity, but it does not mention how to prevent the waist section from directly contacting the heel and ankle, or how to achieve easy on and off functionality for the shoe heel counter itself.

[0005] In addition, some shoe heels can easily cause chafing against the ankle during wear, affecting comfort. For example, the utility model patent with announcement number CN 220275039 U discloses a shoe heel that is formed by hot pressing of a heel counter, a sponge strip, and an inner lining sheet, but it does not solve the problem of the narrow waist of the shoe heel causing chafing against the rear ankle, especially the problem of easily chafing the Achilles tendon.

[0006] In summary, existing shoe heel counters have the following shortcomings: insufficient consideration for ease of on and off, failing to address the chafing issue caused by contact between the heel counter and the rear ankle; inconsistent stability, unable to effectively prevent collapse of the heel counter after prolonged use; and inadequate design consideration for ankle comfort, failing to provide an effective solution to avoid direct contact between the heel counter and the rear ankle. Therefore, developing a new, easy-to-wear, and stable shoe heel counter is particularly necessary. Summary of the Invention

[0007] The purpose of this invention is to provide an easy-to-wear and easy-to-take-off stable heel counter to address the shortcomings of existing heel counters.

[0008] To achieve the above objectives, the technical solution of this utility model is as follows: an easy-to-wear and easy-to-remove stable shoe heel counter, comprising a shoe heel counter body, the shoe heel counter body comprising a wrapping part for wrapping the human heel, a waist-cinching part adapted to the rear ankle, and an outward expansion part located on the upper side of the waist-cinching part for facilitating the insertion of the human heel into the wrapping part; the inner wall surface of the shoe heel counter body is provided with a figure-eight shaped protrusion, the figure-eight shaped protrusion being inclined with the height of the middle area greater than the height of the left and right sides, naturally forming an Achilles tendon space in the middle for avoiding and accommodating the human Achilles tendon; the figure-eight shaped protrusion includes a left protrusion and a right protrusion, the upper surfaces of the left protrusion and the right protrusion being inclined transition surfaces for guiding the heel into the wrapping part.

[0009] Preferably, the left protrusion extends obliquely from the inner wall of the outer extension to the left inner wall of the wrapping part, and the right protrusion extends obliquely from the inner wall of the outer extension to the right inner wall of the wrapping part; the lower surfaces of the left and right protrusions are also oblique transition surfaces to assist the heel in coming out of the wrapping part.

[0010] Preferably, the left and right protrusions extend from the inner wall of the outer extension portion to the inner wall of the wrapping portion, crossing or including the inner wall of the waisted portion, to form a continuous protrusion.

[0011] Preferably, the heel counter body is composed of an outer wrapping layer, a heel shaping device, and an inner wrapping layer. The outer wrapping layer is located on the outer surface of the heel counter body, and the heel shaping device is embedded between the outer wrapping layer and the inner wrapping layer. An inner elastic block is provided at a corresponding position of the inner wrapping layer, so that the surface of the inner wrapping layer presents the figure-eight shaped protrusion.

[0012] Preferably, the outer surface of the outer wrapping layer is provided with a textured surface, and the textured surface is continuously distributed along the direction from the wrapping portion to the outer extension portion.

[0013] Preferably, the raised texture is a continuous wavy or sawtooth ridge, and the height of the ridge gradually decreases from the middle of the heel counter to the left and right sides.

[0014] Preferably, the heel shaping device is an arc-shaped elastic support made of thermoplastic polyester elastomer, the shape of which is adapted to the wrap-around part, or the shape of which is adapted to the shape of the wrap-around part, the waist-cinching part and the outward extension part.

[0015] Preferably, the internal elastic block is a sponge block, a foam material elastic block, or an air bladder.

[0016] Preferably, the upper edge of the outer extension is provided with a edging, which covers the exposed cut of the outer extension.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) The new easy-to-wear and easy-to-remove stable shoe heel counter has a unique figure-eight shaped protrusion design, which brings significant advantages to users. It avoids direct contact between the waist section and the rear ankle, and especially avoids direct contact between the waist section and the Achilles tendon, completely solving the problem of rubbing caused by the waist section of traditional shoe heels contacting the rear ankle and Achilles tendon, greatly improving wearing comfort, which is especially good news for users who wear shoes for long periods of time. The clever combination of the inclined transition surface and the reverse inclined transition surface realizes the convenience of putting on and taking off shoes. The heel can be easily inserted into the wrapping part to complete the putting on of the shoes, reducing the tedious actions such as bending over to lift the shoes, saving time and effort. When taking off the shoes, the reverse inclined transition surface guides the heel out of the wrapping part, making the taking off of the shoes natural and smooth, bringing users an unprecedented convenient experience.

[0019] (2) The heel stabilizer provides excellent stability to the heel counter. It not only prevents deformation of the heel counter during wear but also keeps the heel firmly encased, preventing the shoe from loosening or slipping off, providing a solid guarantee for every step. Furthermore, the thermoplastic polyester elastomer material used in the heel stabilizer possesses excellent elasticity and toughness, withstanding prolonged wear and stretching to ensure the heel counter's stability remains constant. The ingenious use of internal elastic blocks further enhances the heel counter's wrapping and resilience, allowing it to better conform to the shape of the heel, improving stability and comfort.

[0020] (3) The textured design on the outer surface of the outer wrapping layer not only makes the heel of the shoe more visually layered and fashionable, but also makes it easier for the other foot to touch the outside of the back, so that the shoes can be taken off without bending over or using your hands.

[0021] (4) The edge binding cleverly covers the exposed cut of the outer extension, which not only makes the appearance of the shoe back more exquisite and complete, but also effectively prevents the cut from being worn or cracked, extends the service life of the shoe back, and allows the shoe to achieve a perfect balance between aesthetics and practicality.

Detailed implementation mode

[0026] In order to enable the technical content of the present utility model to be understood by those of ordinary skill in the relevant technical field, the present utility model will be described in detail below with reference to the accompanying drawings.

[0027] As Figures 1 to 3 shown, the easy-to-put-on and -take-off stable shoe heel counter of the present utility model includes a shoe heel counter body, and the shoe heel counter body includes a wrapping part 1 for wrapping the human heel, a waist narrowing part 2 adapted to the back ankle, and an outer expansion part 3 located above the waist narrowing part 2 and facilitating the introduction of the human heel into the wrapping part.

[0028] An inverted-V-shaped convex part 4 is provided on the inner wall surface of the shoe heel counter body, and the inverted-V-shaped convex part 4 is in an inclined shape with the height of the middle area being greater than the heights of the left and right sides, similar to the shape of an "eight" or a mustache.

[0029] The inverted-V-shaped convex part 4 includes a left convex part 4.1 and a right convex part 4.2, and a natural Achilles tendon space 4.3 for avoiding and accommodating the human Achilles tendon is formed between the left and right convex parts. The inverted-V-shaped convex part clamps the depressions on both sides of the Achilles tendon to prevent accidental脱出 (should this be "脱出" or a more specific term?) and avoid rubbing the ankle.

[0030] The left convex part 4.1 extends obliquely from the inner wall surface of the outer expansion part 3 towards the left inner wall surface of the wrapping part 1, and the right convex part 4.2 extends obliquely from the inner wall surface of the outer expansion part 3 towards the right inner wall surface of the wrapping part 1. More specifically, the paths of the left convex part 4.1 and the right convex part 4.2 extending from the inner wall surface of the outer expansion part 3 towards the inner wall surface of the wrapping part 1 cross or also include the inner wall surface of the waist narrowing part 2 to form continuous left and right convex parts 4.1 and 4.2.

[0031] The upper side surfaces of the left convex part 4.1 and the right convex part 4.2 are inclined transition surfaces for guiding the heel to penetrate into the wrapping part.

[0032] The lower side surfaces of the left convex part 4.1 and the right convex part 4.2 are also inclined transition surfaces for assisting the heel to脱出 (should this be "脱出" or a more specific term?) from the wrapping part.

[0033] The heel counter is composed of an outer wrapping layer 5, a heel shaping element 6, and an inner wrapping layer 7. The outer wrapping layer 5 is located on the outer surface of the heel counter. The heel shaping element 6 is embedded between the outer wrapping layer 5 and the inner wrapping layer 7. The inner wrapping layer 7 contains an inner elastic block 8 at a corresponding position, thus giving the surface of the inner wrapping layer 7 the appearance of the figure-eight shaped protrusion 4. The inner elastic block 8 is a sponge block, a foam material elastic block, or an air bladder.

[0034] The outer surface of the outer wrapping layer 5 has a textured surface, which is continuously distributed along the direction from the wrapping portion to the outward extension portion. The textured surface consists of wavy or serrated continuous raised ridges, and the height of the raised ridges gradually decreases from the middle of the heel counter to the left and right sides.

[0035] The heel shaping device 6 is an arc-shaped elastic support made of thermoplastic polyester elastomer, the shape of which is adapted to the wrapping part, or the shape of which is adapted to the shape of the wrapping part 1, the waist-cinching part 2 and the outer extension part 3.

[0036] The upper edge of the outer extension 3 is provided with a binding edge 3.1, which covers the exposed cut of the outer extension 3.

[0037] In actual production, different materials and shapes can be selected based on different footwear needs and user preferences. For example, for athletic shoes, materials with high elasticity and abrasion resistance can be chosen to make the heel counter; for casual shoes, the focus can be on appearance design, selecting fashionable materials and textures. At the same time, the shape of the heel counter can also be adjusted according to different shoe shapes to achieve the best wearing effect.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
