A detachable shoe

Abstract

This utility model discloses a detachable shoe, including an upper and a sole assembly. The bottom of the upper has a resilient annular buckle along its circumference, and the outer periphery of the sole assembly has an annular groove. The resilient annular buckle engages with the annular groove through elastic force, achieving a detachable connection between the upper and sole assembly. This utility model, through the resilient annular buckle on the bottom of the upper and the annular groove on the sole assembly, allows for a flexible and detachable connection between the upper and sole assembly. When one component is damaged, the user does not need to discard the entire shoe; only the damaged component needs to be replaced. For example, if the sole is severely worn, only the sole assembly can be replaced; if the upper is damaged, only the upper needs to be replaced. For consumers, this eliminates the need to repeatedly purchase the entire shoe for partial damage, significantly reducing long-term costs. Furthermore, users can flexibly replace the upper or sole assembly according to different usage scenarios.

Description

Technical Field

[0001] This utility model relates to the field of footwear technology, specifically to a detachable shoe. Background Technology

[0002] Currently, most footwear products on the market adopt an integrated structure in which the upper and sole are fixedly connected. This traditional structure has gradually revealed significant drawbacks in actual use, as it neither conforms to the trend of efficient resource utilization nor meets the diverse usage needs of consumers.

[0003] From the perspective of resource utilization and consumption costs, partial damage to integrated footwear can easily lead to the complete scrapping of the entire pair. When the soles suffer severe wear from prolonged walking, the uppers are torn due to scratches and tears, or the insoles lose their elasticity due to sweat, the entire pair of shoes is often forced to be discarded because the individual components cannot be disassembled and replaced. This not only results in a waste of materials for undamaged parts such as the uppers and soles, but also, according to statistics, about 60% of the components in each pair of discarded shoes still have usability, further increasing the economic burden on consumers. Users need to repeatedly purchase the entire pair of shoes for partial damage, significantly increasing long-term consumption costs.

[0004] From a functional adaptability perspective, a one-piece design struggles to meet the needs of different scenarios. Different usage scenarios place significantly different functional requirements on shoes: sports require soles with strong shock absorption, while daily commutes prioritize lightweight design; in summer, breathable and sweat-wicking uppers are needed to prevent foot odor, while in winter, warm and windproof uppers are required; rainy days demand slip-resistant soles and waterproof uppers, while sunny days allow for lighter materials. However, the fixed structure of one-piece footwear prevents the flexible replacement of soles or uppers to suit various needs. Utility Model Content

[0005] Therefore, this utility model provides a detachable shoe to solve the above-mentioned problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] According to a first aspect of the present invention, a detachable shoe includes an upper and a sole assembly. The bottom of the upper is provided with an elastic annular buckle along its circumference, and the outer periphery of the sole assembly is provided with an annular groove. The elastic annular buckle is embedded in the annular groove by elastic force, thereby realizing the detachable connection between the upper and the sole assembly.

[0008] Furthermore, it also includes a fixing device, which includes a flexible wire, a plurality of through holes I disposed on an elastic annular buckle, and a plurality of through holes II disposed in and penetrating the annular groove; the opening direction of the through holes I is consistent with the depth direction of the annular groove, the through holes II are provided in a one-to-one correspondence with the through holes I, and the through holes II are connected to the through holes I, and the flexible wire is sequentially passed through the corresponding through holes I and through holes II to enhance the fixation between the shoe upper and the shoe sole assembly.

[0009] Furthermore, the sole assembly includes an abrasion-resistant layer, a cushioning layer, and an inner bottom layer arranged sequentially from bottom to top; the cross-sectional area of ​​the abrasion-resistant layer is greater than or equal to the cross-sectional area of ​​the inner bottom layer and the cross-sectional area of ​​the cushioning layer, and the annular groove is formed between the abrasion-resistant layer and the inner bottom layer.

[0010] Furthermore, the wear-resistant layer is a one-piece molded structure of wear-resistant rubber with anti-slip texture on the bottom; the shock-absorbing layer has a cavity structure inside, and the second through hole is located on the outer periphery of the shock-absorbing layer and communicates with the cavity structure; the top of the inner bottom layer has a vent hole, which communicates with the cavity structure and the vent hole and the second through hole are connected.

[0011] Furthermore, the cavity structure is provided with a cross-shaped guide groove, and the opening end of the guide groove is connected to the through hole.

[0012] Furthermore, it also includes a T-shaped anti-detachment iron ring, the tail of which is embedded in a through hole, and the head of which abuts against the outer wall of the elastic annular buckle.

[0013] Furthermore, the diameter of the first through hole is larger than the diameter of the second through hole.

[0014] Furthermore, the width of the elastic annular buckle is equal to the width of the annular groove.

[0015] Furthermore, the upper can be any one of mesh, leather, or fabric.

[0016] This invention offers the following advantages: By using an elastic ring buckle at the bottom of the upper and a ring groove in the sole assembly, the upper and sole are elastically detachable. When one component is damaged, the user does not need to discard the entire shoe; only the damaged part needs to be replaced. For example, if the sole is severely worn, only the sole assembly needs to be replaced; if the upper is damaged, only the upper needs to be replaced. This eliminates the need for consumers to repeatedly purchase the entire shoe for partial damage, significantly reducing long-term costs. Furthermore, users can flexibly change the upper or sole assembly according to different usage scenarios. For sports, a highly shock-absorbing sole can be used; for daily commuting, a lightweight sole is preferable. In summer, a breathable, sweat-wicking mesh upper can be used to prevent foot odor; in winter, a warm, windproof leather upper can be chosen; for rainy days, a non-slip sole and waterproof upper can be selected; and for sunny days, a lighter material for the upper and sole can be used. This flexible combination allows the shoes to easily adapt to various scenarios, greatly improving ease of use. Attached Figure Description

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Example 1

[0030] like Figures 1 to 7 As shown in the first aspect embodiment of this utility model, a detachable shoe includes an upper 1 and a sole assembly 2. The bottom of the upper 1 has an elastic annular buckle 11 along its circumference, and the outer periphery of the sole assembly 2 has an annular groove 21. The elastic annular buckle 11 is inserted into the annular groove 21 by elastic force, realizing a detachable connection between the upper 1 and the sole assembly 2. The elastic annular buckle 11 is made of rubber or silicone material with a certain degree of elasticity, and its width is equal to the width of the annular groove 21, ensuring a tight fit after insertion and reducing movement. The upper 1 can be made of different materials such as mesh, leather, or fabric, allowing users to flexibly change it according to the season or usage scenario—for example, choosing a breathable mesh in summer and a warm leather in winter.

[0031] The technical advantages of this embodiment are as follows: The use of elastic ring buckles and ring grooves enables quick disassembly and assembly of the upper and sole components. When the upper or sole is partially damaged, only the corresponding part needs to be replaced, avoiding the scrapping of the entire shoe and reducing material waste and costs. Simultaneously, users can choose different materials for the upper (e.g., breathable, warm) or different functional sole components (e.g., anti-slip, lightweight) to enhance the shoe's adaptability to various scenarios.

[0032] Example 2

[0033] like Figures 1 to 7 As shown, a detachable shoe includes all the contents of Embodiment 1, plus a fixing device. The fixing device includes a flexible wire 31, multiple through holes 32 on the elastic annular buckle 11, and multiple through holes 33 in and through the annular groove 21. The opening direction of the through holes 32 is consistent with the depth direction of the annular groove 21. The through holes 33 correspond one-to-one with the through holes 32 and are connected to each other. The flexible wire 31 is sequentially threaded through the corresponding through holes 32 and through holes 33 to enhance the fixation between the upper 1 and the sole assembly 2. The diameter of the through hole 32 is larger than the diameter of the through hole 33 to facilitate the insertion of the flexible wire 31. The flexible wire 31 can be made of nylon rope or elastic rope, and is fixed by knotting after threading to further prevent the upper and sole assembly from detaching during walking. In addition, it also includes a T-shaped anti-detachment iron ring 4. The tail of the T-shaped anti-detachment iron ring 4 is embedded in the through hole 32, and the head abuts against the outer wall of the elastic ring buckle 11, which can help fix the position of the elastic ring buckle and prevent it from accidentally popping out of the ring groove.

[0034] The technical effect of this embodiment is as follows: Based on the elastic buckle connection, the connection stability between the upper and the sole components is enhanced by the double fixation of the flexible line and the T-shaped anti-slip ring, which prevents the problem of loosening and falling off after strenuous exercise or long-term use. At the same time, it does not affect the convenience of disassembly - after untying the flexible line and taking out the T-shaped anti-slip ring, the upper and the sole can still be easily separated.

[0035] Example 3

[0036] like Figures 1 to 7 As shown, a detachable shoe includes all the contents of Embodiment 2, except that the sole assembly 2 includes an abrasion-resistant layer 22, a cushioning layer 23 and an inner bottom layer 24 arranged sequentially from bottom to top; the cross-sectional area of ​​the abrasion-resistant layer 22 is greater than or equal to the cross-sectional area of ​​the inner bottom layer 24 and greater than the cross-sectional area of ​​the cushioning layer 23, and an annular groove 21 is formed between the abrasion-resistant layer 22 and the inner bottom layer 24.

[0037] Specifically:

[0038] The wear-resistant layer 22 is a one-piece molded structure of wear-resistant rubber with anti-slip texture on the bottom, which improves the wear resistance and anti-slip properties of the sole and extends its service life.

[0039] The shock-absorbing layer 23 has a cavity structure 231 inside, which is filled with elastic sponge or air to improve the shock absorption effect when walking; its outer periphery has a through hole 33, and the through hole 33 is connected to the cavity structure 231.

[0040] The inner bottom layer 24 has a ventilation hole 241 at the top, which is connected to the cavity structure 231 to form an air circulation channel and enhance the breathability of the shoe.

[0041] The cavity structure 231 is provided with a cross-shaped guide groove 232. The open end of the guide groove 232 is connected to the through hole 33, which can guide air to circulate in the cavity and further improve the breathability.

[0042] The technical effects of this embodiment are as follows: through the layered design of the sole components, wear resistance, shock absorption and breathability are taken into account. The wear-resistant layer extends the service life, the shock-absorbing layer improves walking comfort, and the inner bottom layer and the cavity structure work together to enhance breathability and sweat-wicking ability. At the same time, the annular groove structure formed by the wear-resistant layer and the inner bottom layer is stable and adapts to the connection requirements of the elastic annular buckle, making the sole more functional and adaptable to more usage scenarios (such as sports, commuting, etc.).

[0043] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

[0044] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.
