Description

Technical Field

[0001] This invention relates to the field of footwear technology, specifically to a shoe with a front splash-proof and water-blocking structure, and an independent water-blocking edge accessory for shoes that can be sold separately and is compatible with various shoe models. Background Technology

[0002] During daily walking, when people wear casual sneakers or athletic shoes and step on puddles or muddy surfaces, the front of the soles of the shoes will splash water and mud upwards when they come into contact with the water surface. The splashed mud and water can easily stain the shoe surface and trouser legs, causing clothes to get dirty. This problem is particularly prominent when wading through water on rainy days.

[0003] In existing technologies, waterproof shoes mostly use fully sealed waterproof fabric and raised upper designs, which can only prevent rainwater from entering through the shoe shaft and cannot solve the problem of water splashing forward and upward from the ground. The few toe protection accessories on the market only have wear-resistant and impact-resistant functions, and do not have a structural design that directs water flow and blocks mud and water splashes, so they cannot prevent mud and water from splashing onto the shoe upper and trouser legs from the root. At the same time, there is a lack of standardized splash-proof accessories that can be adapted to existing finished shoes and can be individually disassembled / attached, making it costly and lacking in versatility to modify existing shoes. Summary of the Invention

[0004] Purpose of the invention

[0005] To address the shortcomings of existing technologies, such as water splashing and soiling of shoe uppers and trouser legs, poor versatility of splash-proof structures, and lack of standardized independent accessories, this invention provides a splash-proof shoe with a front water-blocking edge and a matching independent water-blocking edge sticker. By setting an outward-extending and downward-facing water-blocking edge structure at the front of the shoe toe, the mud and water generated by stepping are diverted downwards and blocked. At the same time, it provides four implementation structures: integrated sole, integrated toe, embedded, and adhesive, which can be used for both original factory shoe manufacturing and modified finished shoes.

[0006] Technical solution

[0007] In the first aspect, the present invention provides a splash-proof shoe with a front water-blocking edge, the core technical solution of which is as follows: a splash-proof shoe with a front water-blocking edge, including an upper (1), a sole / midsole (3) and a water-blocking edge (2); the upper (1) has a toe area at the front end, and the water-blocking edge (2) is located at the front end of the toe. The water-blocking edge (2) extends forward and downward to form an outward flow guiding structure. When walking and stepping on accumulated water, the water-blocking edge (2) blocks mud and water from splashing upward to the shoe surface.

[0008] Preferred embodiment 1: The water-blocking edge (2) is integrally injection molded with the sole / midsole (3) to form an integral structure of the water-blocking edge and sole. The root of the water-blocking edge (2) is fused and fixed to the upper edge of the front end of the sole (3), which is suitable for the integrated molded mass production of casual skate shoes.

[0009] Preferred embodiment 2: It also includes an independent toe (4), the water-blocking edge (2) and the toe (4) are integrally formed to form an integral structure of water-blocking edge and toe, the toe (4) is fixedly covered on the outer front end of the upper (1), and is adapted to the segmented assembly process of sports shoes.

[0010] Preferred embodiment 3: The water-blocking edge (2) is an independent water-blocking edge patch, with an adhesive surface (2a) on the inner side of the water-blocking edge patch. It is glued to the outer surface of the shoe upper (1) toe by the adhesive surface (2a), serving as an independent accessory that can be sold separately and is compatible with various finished shoes, used to modify existing ordinary shoes on the market. Preferred embodiment 4: The water-blocking edge (2) is an independent insert, with a pressing inner edge (2b) and a pressing vertical surface (2c) on the inner side of the water-blocking edge insert. An inserting groove is reserved between the shoe upper (1) toe and the shoe sole (3), and the pressing inner edge (2b) of the water-blocking edge insert is inserted into the groove and fixed in the assembly interlayer between the shoe toe and the shoe sole by pressing. Furthermore, the water-blocking edge insert has an overall arc-shaped covering structure, with the inner edge (2b) pressed against the inner wall of the shoe toe, the pressing surface (2c) abutting against the front side wall of the shoe upper, and the outer water-blocking edge extending forward to form a splash-proof guide wing, relying on the double-layer pressing structure to improve the sealing firmness.

[0011] Preferably, the water-blocking edge (2) is made of elastic soft rubber material, and the outer end of the water-blocking edge is inclined downward to form a water-collecting and guiding surface, which guides the mud and water splashed up by stepping to the downward slope, preventing mud and water from sticking to the shoe surface and trouser legs. In a second aspect, the present invention provides an independent water-blocking edge sticker for shoes as a matching independent accessory product: an independent water-blocking edge sticker for shoes, which is a matching independent accessory for the above-mentioned anti-splash shoes. The main body is an arc-shaped water-blocking edge (2), and the inner side is formed with an adhesive surface (2a). The adhesive surface (2a) is covered with backing adhesive or suitable adhesive for bonding. It can be pasted alone on the front of the toe of any shoe to achieve the anti-splash function, and can be packaged and sold separately.

[0012] Beneficial effects

[0013] 1. Excellent splash protection: The invention features an outward-turning, downward-extending water-blocking edge at the front of the shoe. When stepping on puddles, water splashes are guided downwards along the sloping edge after contacting the water-blocking edge, physically preventing mud and water from splashing upwards. This completely solves the problem of mud and water getting on trouser legs and shoe uppers, making it highly practical for walking on rainy days and puddles.

[0014] 2. Comprehensive industrialization solutions: Four molding structures are provided to adapt to four major production / use scenarios: integrated sole molding, segmented toe assembly, embedded assembly of finished shoes, and post-installation modification. Both shoe manufacturers and end consumers can benefit from these solutions.

[0015] 3. Independent commercial value of accessories: The standalone protective adhesive waterproof edge patch can be circulated as an independent small commodity. Consumers do not need to replace their shoes, which can modify existing footwear at low cost and has a wide market applicability.

[0016] 4. Robust assembly and strong sealing: The embedded water-retaining edge features a double-limiting pressing structure with a pressed inner edge and a pressed vertical surface, making it difficult to fall off after being embedded in the toe and sole interlayer. It also covers assembly gaps, providing both waterproof and aesthetic benefits. The elastic soft rubber material has good flexibility and follows the deformation of the toe when walking, without causing any discomfort or foreign object sensation.

[0017] 5. Simple structure and low production cost: The whole structure has no complex parts. The one-piece molded style can be produced by mold opening at the same time. The adhesive and embedded styles have simple structures, fewer assembly steps, and low cost for large-scale mass production. Attached Figure Description

[0028] The embodiments of the present invention will now be described in full and clear with reference to the accompanying drawings.

[0029] Example 1: Water-resistant shoes with a one-piece molded water-retaining edge and sole (corresponding accessories included) Figure 1 )

[0030] like Figure 1As shown, this embodiment is a casual sneaker structure, including an upper 1, a sole 3, and a water-retaining edge 2 integrally injection molded with the sole 3, with the two materials fused together without any seams. The water-retaining edge 2 extends outward and downward from the upper edge of the front of the sole, forming an inclined water-collecting surface; when a pedestrian walks on accumulated water, the water splashes upward against the inner inclined surface of the water-retaining edge 2, and the water flows diagonally downward along the inclined surface, preventing it from splashing upward onto the upper and trouser legs. This embodiment is suitable for factory production with newly opened molds, and the one-piece molding provides good waterproof sealing and eliminates the risk of delamination or detachment.

[0031] Example 2: Splash-proof shoes with integrated water-retaining edge and independent toe (corresponding accessories included) Figure 2 )

[0032] like Figure 2 As shown, this embodiment is a sports shoe structure, including an upper 1, a midsole 3, and an independent toe cap 4; the water-retaining edge 2 and the toe cap 4 are integrally injection molded, and the toe cap 4 covers and fixes the outer front end of the upper 1; the midsole 3 has a layered foam structure. Mud splashed up while walking is blocked and guided by the outward-curving water-retaining edge 2 at the front end; the segmented structure is suitable for the assembly line process of sports shoes, and the water-retaining component of the toe cap can be replaced separately, resulting in lower maintenance and replacement costs.

[0033] Example 3: Adhesive independent water-blocking edge sticker (corresponding attachment) Figure 3 Claim 8 (independent product)

[0034] like Figure 3 As shown, this embodiment is a separately sold independent water-retaining edge accessory for shoes. The main body is an arc-shaped elastic soft rubber water-retaining edge 2, with an integrally molded adhesive surface 2a on the inner side. The adhesive surface 2a is pre-coated with adhesive, or shoe glue or double-sided tape can be used for bonding. Consumers can attach this accessory to the outside of the toe of any existing shoe. After attachment, the water-retaining edge extends forward and downward to achieve the splash-proof function without changing shoes. It is compatible with all conventional shoe types such as leather shoes, sneakers, and canvas shoes, and can be sold separately as an independent small product.

[0035] Example 4: Embedded water-retaining shoes with splash guards (corresponding accessories) Figure 4 Appendix Figure 5 )

[0036] like Figure 4 , Figure 5As shown, in this embodiment, the water-blocking edge 2 is an independent arc-shaped insert. The inner side of the insert is simultaneously formed with a pressed inner edge 2b and a pressed vertical surface 2c. A ring-shaped mounting groove is pre-reserved when assembling the shoe upper 1 toe and the midsole 3. During assembly, the pressed inner edge 2b is inserted into the mounting groove between the toe and the midsole, and the pressed vertical surface 2c presses inward against the front side wall of the shoe upper. It is then fixed inside the interlayer through hot pressing and adhesive bonding. The double-layer pressed structure limits the insert, preventing it from lifting or falling off during walking, while also concealing the assembly gap at the toe, achieving both waterproofing and aesthetic effects. The outer side of the insert uniformly extends forward with outward-facing water-blocking and guiding wings, achieving the function of blocking and guiding mud and water. The elastic soft rubber material can bend with the toe, ensuring a comfortable wearing experience without any foreign object discomfort.

[0037] General preferred material description: In all the above embodiments, the water-blocking edge 2 is made of elastic soft rubber materials such as TPR, PVC, and silicone, which have the characteristics of being resistant to bending, wear, and waterproof; the outer end naturally tilts downward at 15° to 40° to form a water-collecting and guiding surface, and the tilt angle can be adjusted according to the size of the shoe to maximize the water-guiding and splash-proof effect.
