Description

TECHNICAL AREA

[0001] The application relates to the technical field of slippers, in particular a slipper with an interchangeable upper. STATE OF THE ART

[0002] Slippers are an everyday necessity. Conventional slippers are usually made from a single piece, where the sole (the part you stand on) and the upper (the part that covers the foot) are permanently attached. This leads to several problems: The appearance is monotonous and doesn't meet the individual needs of the user. The upper cannot be removed, making cleaning extremely cumbersome.

[0003] Patent document CN2549775Y discloses a slipper in which the sole and upper part of the slipper are connected by hook-and-loop fasteners. Although the components are easy to disassemble, clean, and disinfect, they can only be separated from one side. Furthermore, the upper part is fixed in its design, and the buckle is rigidly positioned. Therefore, the slippers cannot be adjusted to the different foot shapes of the wearer and cannot meet the diverse or individual needs of users.

[0004] Patent document CN221082871U discloses a slipper with an interchangeable upper. The slipper includes a sole. A first fastening hole is arranged on the lateral section of the sole. A groove is arranged in the sole. The first fastening hole extends through the side wall of the groove, and the upper is mounted through this first fastening hole. The upper is attached to the sole by means of the fastening strip through interaction with the first fastening hole. This slipper has a complex structure, with the stopper, projection, and end of the fastening strip exposed on the lateral wall of the sole. This leads to foot irritation when walking. Furthermore, the groove and fastening hole are open cavities in which dirt can easily accumulate, posing a hygiene risk. SUMMARY OF THE INVENTION

[0005] To this end, the application provides a slipper with an interchangeable upper to solve the problems with existing slippers, such as lack of compatibility, failure to meet various user needs, or complex structure.

[0006] To achieve the aforementioned tasks, this registration offers the following technical solutions: A slipper with an interchangeable upper comprises a sole and an upper, wherein the left and right edges of the surface of the sole, corresponding to the front area near the sole of the foot, extend upwards to form a left rim and a right rim, wherein at least one left through-hole is provided on the left rim along the width direction of the sole, and at least one right through-hole is provided on the right rim along the width direction of the sole, wherein the two ends of the upper are each passed through the left and right through-holes to form a detachable connection with the outside of the upper.

[0007] Alternatively, a Velcro fastener is provided at each end of the top for attaching it to the outside of the top.

[0008] The two ends of the top part are folded back and glued to the outside of the top part, after the two ends of the top part have been inserted from the inside of the left and right edge ribs and accordingly passed through the left and right openings.

[0009] Optionally, two left-hand through-openings are provided on the left-hand edge rib along the width direction of the sole, and two right-hand through-openings are provided on the right-hand edge rib along the width direction of the sole.

[0010] The upper part consists of a first and a second upper part, wherein the two ends of the first upper part are each passed through a left and a right through-opening, and the two ends of the second upper part are each passed through another right through-opening and another right through-opening, wherein the first and the second upper part are arranged intersecting or parallel to each other and form a detachable connection with their respective ends.

[0011] Optionally, the upper consists of a main body, a left part, and a right part, with the main body positioned directly above the sole to cover the instep. The left and right parts are folded back and glued to the outside of the upper after being inserted from the inside of the left and right rand sections and passed through the left and right openings, respectively, thus attaching the upper to the sole.

[0012] Optionally, the ends of the outer sides of the left and right parts are each fitted with Velcro fasteners, and the entire upper part is made of loop material.

[0013] Alternatively, the width of the left part and the right part is smaller than the width of the main body.

[0014] Optionally, the length of the left part is greater than the length of the right part.

[0015] Or is the length of the right part greater than the length of the left part?

[0016] Optionally, the entire upper part consists entirely of a loop material, with the length of the left part being greater than the length of the right part.

[0017] The outer surface of the main body is equipped with several hook-and-loop fasteners at intervals for connection to the outer surface of the right-hand section. The end of the outer surface of the left-hand section is equipped with a second hook-and-loop fastener for adhesion to the adhesive surface of the folded-back right-hand section.

[0018] Compared to the prior art, this application has at least the following advantageous effects: 1. The application discloses a slipper with an interchangeable upper, comprising a sole and an upper. The left and right edges of the sole's surface extend upwards, forming a left and a right rim. A left and a right through-hole are provided on each of the left and right rims. The two ends of the upper are each passed through the left and right through-holes to form a detachable connection with the outer surface of the upper. The two ends of the upper are then folded back and connected to the outer surface of the upper after being inserted from the inside of the left and right rims and passed through the respective left and right through-holes. The overall structure of this application is simple and easy to assemble / disassemble.The user can interchange different uppers as needed to meet individual requirements. The adhesive hook-and-loop fastener at both ends of the upper can then be freely adjusted to adapt the slipper to the shape of the foot or to improve comfort. When worn, the adhesive surface of this upper is on the outside, thus avoiding direct contact with the foot and reducing pressure. This not only improves comfort but is also visible and easily removable. The tear line is immediately identifiable, allowing for quick removal and replacement of the upper. It is easy to clean, and wear and tear from putting the slipper on and taking it off is reduced, thus extending its lifespan. 2. The outer surface of the upper part of this application is provided with several hook and loop fasteners at intervals, and the entire upper part consists of a loop material (fluff) to achieve reliable adhesion at every point with the hook surface of the hook and loop fasteners. 3. The upper part of this application consists of a main body, a left part, and a right part. The width of the left and right parts is smaller than the width of the main body. This ensures that the two parts are not too wide during insertion and bonding, thus preventing any impairment of the upper part's appearance and comfort. The reduced width also minimizes material consumption, thereby lowering costs while maintaining sufficient strength and stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The application is described in more detail below using exemplary embodiments in conjunction with the attached drawings.

[0022] In the description of this application, "plural" means two or more unless otherwise specified. The terms "first," "second," "third," etc., serve in this application to distinguish the objects mentioned and have no particular technical meaning (they should not, for example, be understood as emphasizing importance or order). Expressions such as "contain," "comprise," and "exhibit" also mean "not limited to" (specific units, components, materials, steps, etc.).

[0023] The terms used in this application, such as "top", "bottom", "left", "right", "middle", etc., are commonly used to indicate the general relative positional relationship for easier intuitive understanding based on the drawings and do not represent absolute limitations of the positional relationship in the actual product. Example 1

[0024] As in Fig. 1, Fig. 2, Fig. 3 to Fig. As shown in Figure 4, a slipper with an interchangeable upper comprises a sole 1 and an upper 2. The left and right edges of the surface of the sole 1, corresponding to the front area near the sole of the foot, extend upwards, forming a left rim 11 and a right rim 12. The left rim 11 and the right rim 12 are integrally formed with the sole 1. The left rim 11 has at least one left through-opening 111 along the width direction of the sole 1. The right rim 12 has at least one right through-opening 121 along the width direction of the sole 1. The two ends of the upper part 2 are each inserted from the inner sides of the left edge bridge 11 and the right edge bridge 12 and accordingly passed through the left through-opening 111 and the right through-opening 121 to form a detachable connection with the outside of the upper part 2.

[0025] Preferably, a hook and loop fastener 3 is provided at each end of the upper part 2 for bonding to any point in the multiple adhesive areas on the outside of the upper part 2 in order to achieve quick fixing and adjustment of the strength.

[0026] When the two ends of the upper part 2 are inserted from the inside of the left edge bridge 11 and the right edge bridge 12, respectively, and passed through the left opening 111 and the right opening 121, they are then folded back and adhered to the outside of the upper part 2. The advantages of this design are: The adhesive surface of the upper part 2 is on the outside, thus preventing injury to the feet and improving wearing comfort. The upper part 2 is visible and easily removable, and the tear is immediately identifiable, allowing for quick removal and replacement of the upper part 2. There are fewer areas that need cleaning, and the structure is simple.

[0027] Preferably, the left rand 11 and the right rand 12 are each concavely shaped inwards, forming a curved surface that adapts to the curvature of the soles of the feet and thus better conforms to the natural shape of the foot. After the upper 2 is inserted, it conforms to the curvature of the two rands (the left rand 11 and the right rand 12), thereby reducing pressure from the shoe edges on the feet and improving comfort. At the same time, the curved design increases the contact area between the upper 2 and the foot, further enhancing comfort and ensuring the footwear is stable and less likely to slip.

[0028] Preferably, the upper part 2 consists of a main body 21, a left part 22, and a right part 23. The main body 21 is located directly above the sole to cover the instep. The left part 22 and the right part 23 are folded back and glued to the outside of the upper part 2 after being inserted from the inside of the left and right edge ribs 11 and 12, respectively, and passed through the left and right openings 111 and 121, thus attaching the upper part 2 to the sole 1.

[0029] Both ends of the outer surface of the upper part 2 are preferably equipped with hook-and-loop fasteners 3. The entire upper part 2 is made of a loop material (fluff material) to ensure reliable adhesion to the hook surface of the hook-and-loop fastener 3 at every point. This allows for adjustment to different foot shapes of the wearer. Naturally, the inner surface of the base body 21 (i.e., the side that touches the foot) can also be made of other, more comfortable materials to further enhance wearing comfort.

[0030] The loop material mentioned above can also be replaced by other materials, as long as they can achieve the bonding effect. Fig. Figure 4 shows a schematic representation of the upper part 2 in an unfolded state, with the hook and loop fastener 3 located at the ends of the left part 22 and the right part 23 and the adhesive area on the outside of the main body 21 on the same side.

[0031] It is further preferred that the width of the left part 22 and the right part 23 is smaller than the width of the main body 21. This ensures that the two parts are not too wide during insertion and bonding, thus preventing any impairment of the appearance and wearing comfort of the upper part 2. The reduced width also reduces material consumption, thereby lowering costs, while ensuring sufficient strength and stability.

[0032] As in Fig. 1 and Fig. As shown in Figure 2, the length of the left part 22 is greater than the length of the right part 23. After the right part 23 has been passed through the right opening 121, it is folded back and its hook-and-loop fastener 3 at its end is adhered to the adhesive area on the outside of the main body 21. After the left part 22 has been passed through the left opening 111, it is folded back and its hook-and-loop fastener 3 at its end is adhered to the adhesive area on the folded-back surface of the right part 23, as shown in Figure 2. Fig. 1 shown. This design not only improves wearing comfort but also enhances the appearance, as visible traces of adhesive are hidden, making the entire top look neat.

[0033] Naturally, the length of the left part 22 can be shorter than the length of the right part 23. The lengths of the left part 22 and the right part 23 can also be the same. In this case, the left part 22, after being passed through the left opening 111, is attached to the left side of the main body 21 with its hook-and-loop fastener 3 at its end. The right part 23, after being passed through the right opening 121, is attached to the right side of the main body 21 with its hook-and-loop fastener 3 at its end.

[0034] Furthermore, 22 cartoon patterns can be arranged on the outside of the left part of the slipper to make it more individual and decorative, and to meet the needs of different users, especially children and teenagers. The cartoon patterns can increase the fun factor and appeal of the slipper.

[0035] The left and right rims 11 and 12 on both sides of the aforementioned sole 1 extend backwards, connecting to form a continuous, circumferential rim. The height of this extending section is less than the height of the left and right rims 11 and 12. Simultaneously, the inner surface of this circumferential rim forms a curved area that corresponds to the curvature of the heel. This prevents the slippers from slipping down while walking, thus making them more comfortable to wear. Example 2

[0036] The second embodiment is essentially the same as the first embodiment, except that the number of left through-openings 111 and right through-openings 121 is two in the second embodiment. In detail, as shown in Fig. As shown in Figure 5, two left-hand passage openings 111 are provided on the left-hand edge rib 11 along the width direction of the sole 1, and two right-hand passage openings 121 are provided on the right-hand edge rib 12 along the width direction of the sole 1;

[0037] The upper part 2 consists of a first and a second upper part. The two ends of the first upper part are each passed through a left through-opening 111 and a right through-opening 121, and the two ends of the second upper part are each passed through another right through-opening 121 and another right through-opening 121. The first and second upper parts are arranged intersecting or parallel to each other and form a detachable connection with their respective ends.

[0038] In other embodiments, the number of left through-openings 111 and right through-openings 121 is not particularly limited and can be determined according to the actual requirements. Example 3

[0039] The third embodiment is essentially the same as Example 1, except that the adhesive surface of the hook and loop fastener 3 is different. In this embodiment, as in Fig. 6 and Fig.Figure 7 shows the entire upper part 2 made of loop material. The length of the left part 22 is greater than the length of the right part 23. Several first hook-and-loop fasteners are arranged at intervals on the outside of the main body 21, the first hook-and-loop fasteners being used to connect to the outside of the right part 23. A second hook-and-loop fastener is provided at the end of the outside of the left part 22, the second hook-and-loop fastener being used to adhere to the folded-back surface adhesive area of ​​the right part 23.

[0040] After the right part 23 has been passed through the right opening 121, it is folded back and then adhered to the outside of the main body 21 using the first hook and loop fasteners. After the left part 22 has been passed through the left opening 111, it is folded back and then further adhered to the corresponding adhesive area on the folded-back surface of the right part 23 using the second hook and loop fastener at its end, thus completing the assembly and attachment of the upper part 2 and the sole 1.

[0041] In summary, this application offers at least the following advantages: 1. The overall structure is simple and easy to assemble / disassemble. The user can exchange different uppers as needed to meet personal requirements. The user can then freely adjust the adhesive hook-and-loop fastener at both ends of the upper to adapt the slipper to the shape of their foot or to improve comfort. 2. When worn, the adhesive surface of the upper is on its outer side, which not only improves foot comfort but is also visible and easy to remove. The tear is immediately recognizable, allowing the upper to be quickly disassembled and replaced, and it is also easy to clean.

[0042] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). To keep the description concise, not all possible combinations of the technical features of the above embodiments are described. Embodiments not explicitly described fall within the scope of this description. QUOTES INCLUDED IN THE DESCRIPTION
