Description

Technical Field

[0001] This utility model relates to the field of footwear technology, and more specifically, to a shoe heel device for quick shoe putting on. Background Technology

[0002] Existing shoes typically require users to bend over, pull up the heel, or adjust the tongue when putting them on, a cumbersome and inconvenient process. Although some shoe models incorporate auxiliary structures at the heel, they generally suffer from insufficient rebound, lack of ergonomic three-dimensional support, and poor on-and-off experience. Therefore, there is an urgent need for a heel device that can automatically rebound, conform to the foot shape, and enable quick shoe-wearing. Utility Model Content

[0003] The purpose of this invention is to provide a shoe heel device for quick shoe-wearing, which can guide the foot to slide in when putting on shoes and automatically rebound and wrap around the heel after putting them on, achieving a quick shoe-wearing experience without lifting or tying.

[0004] The embodiments of this utility model are implemented as follows: This application provides a quick-wearing shoe heel device, including an inner support shell and an outer sleeve. The outer sleeve includes an upper sleeve and two lower sleeves. The two ends of the upper sleeve are respectively connected to the two lower sleeves, forming a semi-arc structure that fits snugly to the heel. Each lower sleeve is connected to the sole. Each lower sleeve is provided with a memory beam extending along the direction of the semi-arc structure. One end of each of the two memory beams extends onto the upper sleeve. The memory beams can return to their initial state after deformation. The shape of the inner support shell is adapted to the shape of the upper sleeve and fits snugly onto the upper sleeve.

[0005] In some embodiments of this utility model, the top of the inner support shell is provided with a cushion guide edge, which is used to guide the heel into the shoe.

[0006] In some embodiments of this utility model, the middle part of the inner support shell is an arc-shaped structure adapted to the heel of the shoe, and the surface of the arc-shaped structure is provided with protrusions.

[0007] In some embodiments of this utility model, the protrusion is an elliptical structure, and the upper sleeve has an elliptical perforation adapted to the protrusion.

[0008] In some embodiments of this utility model, each of the lower components is provided with a foot support at its bottom.

[0009] In some embodiments of this invention, the memory beam end away from the upper kit extends to the foot support.

[0010] In some embodiments of this utility model, the memory beams are all disposed inside the upper and lower kits.

[0011] In some embodiments of this utility model, the thickness of the upper sleeve at the elliptical perforation gradually increases from the inside out.

[0012] In some embodiments of this utility model, the inner support shell is detachably connected to the upper kit.

[0013] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects: 1. Quick Automatic Shoe Putting-On: This device is fixedly installed at the heel of the shoe. When putting on the shoe, the user's toes first insert into the shoe. When the user's heel reaches the heel, a downward pressure is applied to the inner support shell, causing the inner support shell to exert force on the outer sleeve. This deforms the corresponding two memory beams, pressing down at the heel, thus facilitating the complete entry of the foot into the shoe. Once the foot is inside the shoe, the downward pressure on the inner support shell ceases, and the memory beams return to their initial positions, causing the inner support shell and outer sleeve to elastically rebound. This allows for a smooth sliding of the foot and automatic heel wrapping, enabling quick shoe putting without manual pulling.

[0014] 2. Comfortable fit: The three-dimensional composite structure of the inner support shell and the outer sleeve closely fits the curve of the human heel, conforms to ergonomics, and effectively avoids blisters and discomfort. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Example Please refer to Figures 1-9 This embodiment provides a quick-wearing shoe heel device, including an inner support shell 1 and an outer sleeve. The outer sleeve includes an upper sleeve 2 and two lower sleeves 3. The two ends of the upper sleeve 2 are respectively connected to the two lower sleeves 3, forming an arc-shaped structure that fits snugly to the heel of the shoe. Each lower sleeve 3 is connected to the sole of the shoe. Each lower sleeve 3 is provided with a memory beam 4 extending along the arc-shaped structure. One end of each of the two memory beams 4 extends onto the upper sleeve 2. The memory beams 4 can return to their initial state after deformation. The shape of the inner support shell 1 is adapted to the shape of the upper sleeve 2 and fits snugly onto the upper sleeve 2.

[0021] The device is fixedly installed at the heel of the shoe. When putting on the shoe, the user's toes first enter the shoe. When the user's heel reaches the heel, a downward pressure is applied to the inner support shell 1, causing the inner support shell 1 to exert force on the outer sleeve. This deforms the corresponding two memory beams 4, pressing down at the heel, thus facilitating the complete entry of the foot into the shoe. Once the foot is inside the shoe, the downward pressure on the inner support shell 1 ceases, and the memory beams 4 return to their initial positions, causing the inner support shell 1 and the outer sleeve to elastically rebound. This allows for a smooth sliding of the foot and automatic heel wrapping, enabling quick shoe-wearing without the need for manual pulling.

[0022] Specifically, the material of the inner support shell 1 mentioned above may include one or more supporting and shaping materials: for example: heel counter, TPU rigid material, thermoplastic rubber, rubber, nylon, silicone resin, ABS, EVA, TPR, PU, ​​PVC and other shoe materials, and aluminum, aluminum alloy may also be used.

[0023] Please refer to Figure 2 Furthermore, in some embodiments of this example, the top of the inner support shell 1 is provided with a cushion guide edge 5, which is used to guide the heel into the shoe.

[0024] The guide edge 5 features an arc-shaped design, its curvature conforming to the contour of the heel. This better conforms to the shape of the heel, providing smooth guidance as the heel enters the shoe, reducing friction between the heel and the inner support shell 1, and further enhancing the comfort and ease of wearing the shoe. Specifically, the guide edge 5 is made of a soft and somewhat elastic material, ensuring that it does not squeeze or scratch the heel during the process of guiding the heel into the shoe, thus avoiding discomfort for the user.

[0025] Please refer to Figure 2 and Figure 3 In this embodiment, the middle part of the inner support shell 1 is an arc-shaped structure 6 adapted to the heel of the shoe, and the surface of the arc-shaped structure 6 is provided with a protrusion 7. Preferably, in this embodiment, the protrusion 7 is an elliptical structure, and the upper sleeve 2 is provided with an elliptical perforation 9 adapted to the protrusion 7. The protrusion 7 and the elliptical perforation 9 are adapted to each other and can play a positioning role, which facilitates the installation of the inner support shell.

[0026] When the heel enters the shoe and contacts the inner support shell 1, the oval protrusion 7 can form multiple points of contact with the heel surface, increasing friction and preventing the foot from sliding inside the shoe, thus stabilizing the foot position. At the same time, the oval perforation 9 is not only easy to install with the oval protrusion 7 in terms of manufacturing process, but also allows air to circulate inside the shoe during foot movement, which enhances the breathability of the shoe to a certain extent, reducing the stuffiness and dampness of the feet caused by wearing shoes for a long time, and further improving the comfort of wearing them.

[0027] Please refer to Figure 3 Preferably, in this embodiment, each of the lower components 3 is provided with a foot support 8 at its bottom. The shape of the foot support 8 is adapted to the shape of the sole of the foot, providing stable support for the corresponding lower component 3. Specifically, the foot support 8 is inserted into the gaps on both sides inside the shoe, which can further improve the connection stability with the shoe.

[0028] Please refer to Figure 3 Furthermore, in this embodiment, one end of the memory beam 4, away from the upper component 2, extends to the foot support 8. Extending the memory beam 4 to the foot support 8 enhances the overall structural stability.

[0029] It is worth noting that in this embodiment, the memory beams 4 are all located inside the upper kit 2 and the lower kit 3. Because the memory beams 4 are located inside the upper kit 2 and the lower kit 3, they are not in direct contact with the outside world, thus avoiding the impact of external environmental factors such as friction and collision on their performance, and ensuring the service life and stability of the memory beams 4.

[0030] Preferably, the thickness of the upper sleeve 2 at the aforementioned elliptical perforation 9 gradually increases from the inside out. This structure provides the upper sleeve 2 with better structural strength at the elliptical perforation 9, enabling it to withstand greater pressure generated during foot movement and reducing the likelihood of deformation or damage. Simultaneously, the gradually increasing thickness from the inside out also helps to distribute the pressure of the foot on the upper sleeve 2 to a certain extent, resulting in a more even pressure distribution and further improving wearing comfort and the durability of the heel counter.

[0031] Preferably, the inner support shell 1 and the upper assembly 2 are detachably connected. When the inner support shell 1 is damaged or needs to be replaced with a different size inner support shell 1 to meet different needs, it is not necessary to replace the entire heel counter; simply remove the inner support shell 1 from the upper assembly 2 and then install the new inner support shell 1. This not only saves costs but also improves the flexibility and maintainability of the heel counter. Furthermore, the detachable connection facilitates separate cleaning and maintenance of the inner support shell 1 and the upper assembly 2, helping to maintain the hygiene and performance of the heel counter.

[0032] Please refer to Figures 4-6In use, the user simply inserts their foot into the shoe, starting with the toes. As the heel reaches the heel counter, a downward pressure is applied to the inner support shell 1, causing it to exert force on the outer sleeve. This deforms the two memory beams 4, pressing down on the heel and facilitating a full entry into the shoe. Once the foot is inside, the downward pressure on the inner support shell 1 ceases, and the memory beams 4 return to their initial positions, causing the inner support shell 1 and outer sleeve to spring back elastically. This allows for a smooth slip-in of the foot and automatic heel wrapping, enabling quick and easy shoe-wearing without the need for manual pulling.

[0033] Please refer to Figures 7-9 In this embodiment, the quick-put-on shoe heel device can also be directly used in sandals. The quick-put-on shoe heel device can be directly set in the heel of the sandal to replace the existing heel of the sandal. Similarly, after the user's toes first insert into the sandal, as they continue to insert, the heel will generate a downward pressure on the inner support shell 1, thereby deforming the outer sleeve and the memory beam 4 inside the outer sleeve, thus compressing them downwards. In this way, there is no need to deliberately lift the heel. When the user's foot is fully inserted into the sandal, under the action of the memory beam 4, the inner support shell 1 and the outer sleeve return to their initial positions along with the memory beam 4.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
