Description

Technical Field

[0001] This application relates to the field of footwear technology, and in particular to a casual shoe with an anti-hardening upper. Background Technology

[0002] Casual shoes, as an important category of footwear, are popular among consumers due to their versatility for various occasions, such as daily commutes, sports and fitness, and leisure travel. The booming casual shoe market has prompted major footwear companies to continuously invest in research and development, striving to improve product quality to meet the ever-changing needs of consumers. This has not only driven technological innovation in the footwear industry but also provided consumers with more choices and a better shopping experience.

[0003] After prolonged use, the upper of traditional casual shoes may undergo irreversible deformation, causing it to harden. Once the upper hardens, the fit between the shoe and the foot decreases significantly, easily leading to problems such as pressure on the instep and blisters, greatly affecting comfort during long walks or exercise. Therefore, there is a need for casual shoes that can delay the hardening of the upper. Utility Model Content

[0004] In order to delay the hardening effect of the shoe upper, this application provides a casual shoe with an anti-hardening upper.

[0005] The present application provides a non-hardening casual shoe with an upper, which adopts the following technical solution:

[0006] A casual shoe with anti-hardening upper includes an upper, which comprises a surface layer, an elastic layer, and an inner layer arranged sequentially from the outside to the inside; the elastic layer includes an elastic skeleton and elastic elements, the elastic skeleton is provided with multiple reset grooves, and the elastic elements are provided in multiple sets, with all elastic elements respectively installed in each reset groove.

[0007] By adopting the above technical solution, the elastic skeleton provides basic support for the shoe upper through its rigid structure, delaying the irreversible collapse of the shoe upper under long-term stress. Placing elastic holes in areas of the shoe upper that are frequently bent (such as the toe box and tongue joint) can enhance the elastic recovery ability of these areas; the elastic components in these areas can more effectively absorb the stress generated during bending, reducing material fatigue and thus delaying the collapse or hardening of the shoe upper in these areas.

[0008] Optionally, the elastic element includes two elastic sheets, both of which are installed in the elastic hole and cover the opposite sides of the reset groove.

[0009] By adopting the above technical solution, the gap between the elastic sheets provides physical space for bending, allowing the shoe upper to deform regularly along a preset path when subjected to force; enabling the shoe upper to quickly return to its original shape after bending and maintain flatness.

[0010] Optionally, the elastic element further includes a plurality of elastic pillars, all of which are installed in the elastic holes, and the two ends of the elastic pillars are respectively connected to two elastic sheets.

[0011] By adopting the above technical solution, when the elastic sheet approaches the critical deformation, the elastic column resists further compression, thus preventing the elastic sheet from entering the plastic deformation stage (i.e., irreversible deformation).

[0012] Optionally, the elasticity of the elastic sheet is less than that of the elastic column.

[0013] By adopting the above technical solution, when the elastic sheet is bent under pressure, the elastic column stores energy through its own high elasticity and releases it quickly after the external force disappears, actively pushing the elastic sheet to reset, further reducing the occurrence of irreversible deformation of the elastic sheet.

[0014] Optionally, both the elastic sheet and the elastic skeleton are provided with ventilation holes.

[0015] By adopting the above technical solution, the design of the ventilation holes can increase the breathability of the shoe and improve the comfort of wearing it.

[0016] Optionally, the elasticity of the elastic sheet is greater than that of the elastic skeleton.

[0017] By adopting the above technical solutions, when the elastic sheet has greater elasticity, the upper is preferentially deformed by the elastic sheet when subjected to force, reducing the resistance of the skeleton to bending. For example, during running, the toe box can quickly respond to foot movements, reducing energy loss.

[0018] Optionally, the surface layer is made of a knitted material and is coated with an anti-hardening coating.

[0019] By adopting the above technical solutions, the flyknit material can increase the breathability of the shoe upper; while the anti-hardening coating can prevent the shoe upper from hardening.

[0020] Optionally, the inner layer is made of cotton fabric.

[0021] By adopting the above technical solution, the cotton fabric is soft and has mesh, which can improve the comfort of wearing the shoe while improving its breathability.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The elastic skeleton provides basic support for the shoe upper through its rigid structure, delaying the irreversible collapse of the shoe upper under long-term stress; in addition, the elastic holes are opened in the areas of the shoe upper that are frequently bent, which can enhance the elastic recovery ability of these areas; the elastic elements can more effectively absorb the stress generated during bending in these areas, reduce material fatigue, and thus delay the collapse or hardening of the shoe upper in these areas.

[0024] 2. By setting up elastic columns, when the elastic sheet approaches the critical deformation, the elastic columns resist further compression, thus preventing the elastic sheet from entering the plastic deformation stage. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0029] This application discloses a casual shoe with an anti-hardening upper.

[0030] Reference Figure 1 and Figure 2 A type of casual shoe with an anti-hardening upper 2 includes an upper 2 and a sole 1 connected to the upper 2. The upper 2 includes a surface layer 3, an elastic layer 5, and an inner layer 4 arranged sequentially from the outside to the inside. The surface layer 3, the elastic layer 5, and the inner layer 4 are pasted together in sequence. This arrangement facilitates the processing of the upper 2.

[0031] The outer layer 3 is made of flyknit material, which is lightweight, breathable, and flexible, making it ideal for the upper 2 of casual shoes. Its woven structure allows for better airflow, keeping feet dry and comfortable. Simultaneously, the outer layer 3 is coated with an anti-hardening coating, which acts as a barrier against external environmental factors, such as humidity and temperature changes, preventing direct impacts on the upper 2 material and slowing down material aging. This anti-hardening coating can be a high-molecular polymer coating with good weather resistance and abrasion resistance. Of course, besides flyknit material, the outer layer 3 can also be replaced with other materials with similar breathable and flexible properties, such as mesh, achieving the same level of breathability and comfort.

[0032] Reference Figure 2 The elastic layer 5 includes an elastic skeleton 51 and elastic elements 52. The elastic skeleton 51 and elastic elements 52 cooperate with each other to form the cushioning and restoring function of the elastic layer 5. The elastic skeleton 51 is provided with multiple elastic holes 55, which are mainly opened in the frequently bending areas of the shoe upper 2, such as the toe and the connection of the shoe tongue. Multiple sets of elastic elements 52 are provided, and all elastic elements 52 are installed in each elastic hole 55.

[0033] The elastic skeleton 51 can be made of materials with high elasticity and toughness, such as rubber. This material can quickly return to its original shape after being squeezed, ensuring the long-term effective use of the elastic layer 5.

[0034] Specifically, the elastic element 52 includes multiple elastic pillars 53 and two elastic sheets 54. Both elastic sheets 54 are installed on the inner wall of the elastic hole 55, and the two elastic sheets 54 cover the opposite sides of the reset groove so that there is a gap between them. In this embodiment, the elastic sheet 54 is made of rubber material. The elastic force of the elastic sheet 54 is greater than the elastic force of the elastic skeleton 51. When the shoe upper 2 is subjected to force, the elastic sheet 54 provides deformation first, reducing the resistance of the skeleton to bending.

[0035] All elastic posts 53 are installed in the reset slots. Each end of an elastic post 53 is connected to one of two elastic plates 54. The elastic posts 53 can be made of elastic components such as rubber posts, and the elastic force of the elastic posts 53 is greater than that of the elastic plates 54. Taking a rubber post as an example, when the elastic plate 54 is bent under pressure, the elastic post 53 stores energy through its high elasticity and releases it quickly after the external force disappears, actively pushing the elastic plate 54 to reset, further reducing the possibility of irreversible deformation of the elastic plate 54.

[0036] Specifically, both the elastic skeleton 51 and the elastic sheet 54 are provided with ventilation holes 56. The ventilation holes 56 can be in different shapes such as round or square, and their size and distribution density can be adjusted according to the specific needs of the shoe upper 2. The ventilation holes 56 can increase the breathability of the shoe and improve the comfort of wearing the shoe.

[0037] Specifically, the inner layer 4 is made of cotton fabric, which is soft, skin-friendly, and absorbent, allowing it to directly contact the skin of the feet and provide a comfortable wearing experience. Furthermore, cotton fabric has a certain degree of breathability, helping the outer layer 3 and elastic layer 5 to keep the inside of the shoe upper 2 dry. Besides cotton, the inner layer 4 can also be replaced with other soft and skin-friendly materials such as silk.

[0038] Reference Figure 1 The sole 1 is made of EVA material, which is soft and elastic and can increase the breathability of the shoe.

[0039] The implementation principle of this embodiment is as follows: the elastic skeleton 51 can provide rigid support for the upper 2, so that the upper 2 can conform to the curve of the foot when worn, increasing the comfort of wearing the shoe; and when the upper 2 collapses due to external force, the elastic deformation capability of the skeleton itself can provide a restoring force, so that the upper 2 can return to its original state.

[0040] In addition, by opening the elastic holes 55 in the areas of the shoe upper 2 that are frequently bent, the elastic recovery ability of these areas can be enhanced; the elastic element 52 can more effectively absorb the stress generated during bending in these areas, reduce material fatigue, and thus delay the collapse or hardening of the shoe upper 2 in these areas.

[0041] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
