Abstract
Description
Technical Field
[0001] This utility model relates to the field of rain boot technology, specifically to an overcoat-style rain boot. Background Technology
[0002] Rain boots are waterproof shoes worn in the rain. They are generally made of rubber and have good waterproof properties, so water will not get inside the boots even when wading. Rain boots are classified into low-top, mid-top, and high-top rain boots according to their boot height. Low-top and mid-top rain boots are more common in daily life.
[0003] There are two types of existing overcoat rain boots. One type is ordinary rain boots, which users may need to change shoes for, for example, when outdoors to avoid getting their shoes and trousers wet, and when going indoors they may need to change back into leather shoes, high heels, sneakers, etc., which is quite troublesome in practice. The other type can be directly slipped over shoes, but it also encounters various problems when used. For example, if the user's shoes are large and the rain boots are mid- to high-top rain boots, it is very troublesome to put them on. Also, mud and dirt stuck to the soles can easily get inside the rain boots, causing the mud and dirt stuck inside the rain boots to easily transfer to the trousers after the rain boots are put on. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide an overcoat-style rain boot to solve the technical problems mentioned in the background section.
[0005] To achieve the above objectives, the present invention provides the following technical solution: an overcoat-style rain boot, comprising a shoe body and a shoe shaft, wherein a waterproof zipper is connected to the back of the shoe body and the shoe shaft; a water-retaining sleeve is connected to the lower part of the outer surface of the shoe body through a fixed area; and a first threading sleeve is connected to both sides of the water-retaining sleeve, wherein a first limiting rope is connected inside the first threading sleeve.
[0006] By adopting the above technical solution, the water-repellent cover is only fixed to the shoe body through a fixed area on its lower interior. This fixed area, consisting of a two-component polyurethane adhesive and a stitching distribution path parallel to the bottom of the water-repellent cover, is located below the waterproof zipper. This means that the outer surface of the water-repellent cover, when rolled down, will not block the waterproof zipper. The inside and upper part of the water-repellent cover only contact the shoe body and boot shaft. Therefore, before wearing, the user rolls the water-repellent cover down, similar to rolling up trouser legs, except that the cover rolls down while trouser legs are usually rolled up. Afterward, pulling down the waterproof zipper opens the upper part of the shoe body and boot shaft, allowing the user to directly place their foot and lower leg inside the shoe body and boot shaft, avoiding the need for other precautions when wearing rain boots. The shoes pass through the top of the boot shaft, causing mud and sand to transfer onto the trousers. After putting on the rain boots, the user zips up the waterproof zipper. The waterproof zipper has good closure and can effectively prevent water splashing, thus reducing the possibility of water entering the rain boots. Then, the user flips the water-retaining sleeve upwards to make it stand upright, increasing the wading height of the rain boots and preventing water pressure in puddles from causing water to seep through the waterproof zipper and into the boot body and shaft. Next, the user tightens the first limiting rope to make the top of the water-retaining sleeve fit tightly against the boot shaft. The water-retaining sleeve is made of TPU material, which has good elasticity and can fill gaps, thus preventing rainwater from accumulating and seeping into the gap between the water-retaining sleeve and the boot body and shaft. Then, the first limiting rope can be used to limit the contact pressure between the water-retaining sleeve and the boot shaft.
[0007] Furthermore, the bottom of the shoe body is fixed with an anti-slip sole, and the shoe shaft is fixed to the top of the anti-slip sole.
[0008] By adopting the above technical solutions, the anti-slip sole increases the friction with the ground, avoiding slipping due to wet ground. The design of the shoe shaft increases the waterproof area, reducing rain splashes and drips that could wet trousers.
[0009] Furthermore, the shoe body, non-slip sole, and shoe shaft are all made of rubber.
[0010] By adopting the above technical solutions, the one-piece rubber upper, non-slip sole, and shoe shaft effectively prevent rainwater from penetrating and provide good waterproofing.
[0011] Furthermore, a sealing sleeve is connected to the top of the shoe shaft, and second threading sleeves are connected to both sides of the sealing sleeve, with a second limiting rope connected inside the second threading sleeve.
[0012] By adopting the above technical solution, the user can tighten the second limiting rope to make the sealing sleeve fit snugly against the user's pants, preventing rainwater from entering from the top of the shoe.
[0013] Furthermore, both the first and second limiting ropes are nylon ropes or polyester fiber ropes.
[0014] By adopting the above technical solutions, nylon ropes have extremely high strength, toughness, excellent elasticity, good abrasion resistance, flexibility, chemical resistance, and high wet strength; polyester fiber ropes have excellent UV resistance, extremely low water absorption, low creep, high strength, good abrasion resistance, chemical resistance, and heat resistance, and are less expensive than nylon ropes, and can be selected according to different needs.
[0015] Furthermore, both the water-blocking sleeve and the sealing sleeve are made of polyester TPU, polyether TPU, or aliphatic TPU.
[0016] By adopting the above technical solutions, polyester-type TPU has good mechanical properties, oil resistance, and lower cost; polyether-type TPU has excellent hydrolysis resistance, low temperature resistance, and mildew resistance, making it more suitable for long-term water immersion environments, but its cost is slightly higher than that of polyester-type TPU; aliphatic TPU is resistant to yellowing and has high transparency, making it suitable for parts with high appearance requirements, and can be selected according to different needs.
[0017] Furthermore, the sealing sleeve is fixedly connected to the shoe shaft by an overlapping method using a two-component polyurethane adhesive and stitching.
[0018] By adopting the above technical solution, a large overlap area is achieved, providing good connection stability during extrusion. Mechanical fixation via stitching is combined with adhesive fixation using a two-component polyurethane adhesive. The two-component polyurethane adhesive and the TPU sealing sleeve have excellent compatibility, forming a strong and tough connection. It also has excellent adhesion to the rubber shoe upper. The two complement each other to ensure the stability of the sealing sleeve connection. Furthermore, the two-component polyurethane adhesive has excellent flexibility and elasticity to adapt to the deformation of the sealing sleeve, and it also has good waterproof properties to prevent water seepage in the fixing area.
[0019] Furthermore, the fixing area is a two-component polyurethane adhesive and suture.
[0020] By adopting the above technical solution, mechanical fixation with sewing is combined with bonding fixation using a two-component polyurethane adhesive. The two-component polyurethane adhesive and the TPU water-retaining sleeve have excellent compatibility, forming a strong and tough connection. It can also bond well with the rubber shoe body and rubber shoe shaft. The two complement each other to ensure the stability of the water-retaining sleeve connection. Furthermore, the two-component polyurethane adhesive has excellent flexibility and elasticity to adapt to the deformation of the water-retaining sleeve, and it has good waterproof properties to prevent water seepage in the fixing area.
[0021] In summary, the present invention has the following main advantages:
[0022] 1. This utility model features a waterproof zipper that allows the top of the shoe body and the boot shaft to be opened, making it easy for the user to directly insert their foot and lower leg into the shoe body and boot shaft. This prevents mud and sand from being transferred when the shoe passes through the top of the boot shaft. After putting on the rain boots, the waterproof zipper can be zipped up. The waterproof zipper has good closure and can effectively prevent water splashes, thereby reducing the occurrence of water entering the rain boots. It is convenient to wear and prevents mud and sand from being transferred from the sole of the shoe to the pants.
[0023] 2. This utility model, through the design of the water-blocking sleeve, allows for the following operation: before putting on rain boots, the water-blocking sleeve is rolled down, similar to rolling up trouser legs. The difference is that the water-blocking sleeve is rolled down while the trouser legs are usually rolled up. After putting on the rain boots, the water-blocking sleeve is flipped back up to make it stand upright, increasing the wading height of the rain boots and preventing water pressure in puddles from causing water to seep into the waterproof zipper and into the boot body and shaft; thus increasing the wading height and improving practicality.
[0024] 3. This utility model, through the setting of the first threading sleeve and the first limiting rope, allows the water-blocking sleeve to be flipped up and reset after being repositioned. By tightening the first limiting rope, the top of the water-blocking sleeve can be made to fit tightly against the shoe shaft. The water-blocking sleeve is made of TPU material, which has good elasticity and can fill gaps, thereby preventing rainwater from entering the gap between the water-blocking sleeve and the shoe body and shoe shaft, thus preventing water accumulation and seepage. Then, the first limiting rope can be used to limit and ensure the contact pressure between the water-blocking sleeve and the shoe shaft, further improving the waterproof effect of the water-blocking sleeve.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0032] The embodiments of this utility model will be described below based on its overall structure.
[0033] Example 1:
[0034] A type of overcoat-style rain boot, such as Figures 1-4 As shown, the shoe includes a shoe body 1 and a shoe shaft 3, with a waterproof zipper 4 connecting the back of the shoe body 1 and the shoe shaft 3. A water-retaining sleeve 5 is connected to the lower outer surface of the shoe body 1 via a fixing area 8. The water-retaining sleeve 5 is made of polyester TPU, polyether TPU, or aliphatic TPU. First threaded loops 6 are connected to both sides of the water-retaining sleeve 5. A first limiting rope 7 is connected inside the first threaded loop 6. The first limiting rope 7 is made of nylon rope or polyester fiber rope. The water-retaining sleeve 5 is only fixed to the shoe body 1 through the fixing area 8 on the lower inner side. The two-component polyurethane adhesive and stitching distribution path are parallel to the bottom of the water-retaining sleeve 5, and the fixing area 8 corresponding to the waterproof zipper 4 is located below the waterproof zipper 4. This means that when the outer surface of the water-retaining sleeve 5 is rolled down, it will not block the waterproof zipper 4. The inside and upper part of the water-retaining sleeve 5 only contact the shoe body 1 and the shoe shaft 3. Therefore, before wearing, the user rolls the water-retaining sleeve 5 down, similar to rolling up a trouser leg. The difference is that the water-retaining sleeve 5 is rolled down while the trouser leg is usually rolled up. Afterwards, use... By pulling down the waterproof zipper 4, the upper part of the shoe body 1 and the shoe shaft 3 can be opened, allowing the user to directly place their foot and lower leg into the shoe body 1 and shoe shaft 3, preventing mud and sand from being transferred to their trousers when the shoe passes through the top of the shoe shaft 3. After putting on the rain boots, the user can zip up the waterproof zipper 4. The waterproof zipper 4 has good closure and can effectively prevent water splashes, thereby reducing the occurrence of water entering the rain boots. Then, the user can flip the water-retaining cover 5 upwards so that the water-retaining cover 5 is upright. The wading height of the rain boots is increased to prevent water from seeping into the shoe body 1 and shoe shaft 3 due to water pressure in puddles. Then, the user tightens the first limiting rope 7 to make the top of the water-blocking sleeve 5 fit tightly against the shoe shaft 3. The water-blocking sleeve 5 is made of TPU material with good elasticity and can fill gaps, thereby preventing rainwater from entering the gap between the water-blocking sleeve 5 and the shoe body 1 and shoe shaft 3 and causing water accumulation and seepage. Then, the first limiting rope 7 can limit the contact pressure between the water-blocking sleeve 5 and the shoe shaft 3.
[0035] See Figure 1 and Figure 3In the above embodiment, the bottom of the shoe body 1 is fixed with an anti-slip sole 2, and the shoe shaft 3 is fixed to the top of the anti-slip sole 2. The shoe body 1, the anti-slip sole 2 and the shoe shaft 3 are all made of rubber material. The rubber integrated shoe body 1, anti-slip sole 2 and shoe shaft 3 effectively prevent rainwater from passing through and provide good waterproof performance.
[0036] Example 2:
[0037] Based on the above embodiment one, in order to increase the waterproofness of this rain boot, the following settings are now implemented.
[0038] See Figure 1 , Figure 2 , Figure 3 and Figure 5 In the above embodiment, a sealing sleeve 9 is connected to the top of the shoe shaft 3. The sealing sleeve 9 is made of polyester TPU, polyether TPU or aliphatic TPU. The sealing sleeve 9 is fixedly connected to the shoe shaft 3 by overlapping with a two-component polyurethane adhesive and stitching. A second threading sleeve 10 is connected to both sides of the sealing sleeve 9. A second limiting rope 11 is connected inside the second threading sleeve 10. The second limiting rope 11 is a nylon rope or polyester fiber rope. The user pulls the second limiting rope 11 tight to make the sealing sleeve 9 fit the user's pants to prevent rainwater from entering from the top of the shoe shaft 3.
[0039] Example 3:
[0040] Based on the above embodiment 1, in order to ensure that the water-blocking sleeve 5 is stably fixed and does not affect the operation of the waterproof zipper 4, the following settings are now adopted.
[0041] See Figure 4 In the above embodiment, the fixing area 8 is a two-component polyurethane adhesive and stitching. It is mechanically fixed by stitching and bonded by the two-component polyurethane adhesive. The two-component polyurethane adhesive has excellent compatibility with the TPU water-blocking sleeve 5, which can form a strong and tough connection. It can also bond well with the rubber shoe body 1 and the rubber shoe shaft 3. The two complement each other to ensure the stability of the connection of the water-blocking sleeve 5. The two-component polyurethane adhesive has excellent flexibility and elasticity to adapt to the deformation of the water-blocking sleeve 5, and has good waterproof properties to prevent water seepage in the fixing area.
[0042] The implementation principle of this utility model is as follows: First, the water-blocking sleeve 5 is only fixed to the shoe body 1 through the fixed area 8 at the lower inside. The fixed area 8, namely the two-component polyurethane adhesive and the stitching distribution path, is parallel to the bottom of the water-blocking sleeve 5. The fixed area 8 corresponding to the waterproof zipper 4 is located below the waterproof zipper 4. That is, after the outer surface of the water-blocking sleeve 5 is rolled down, it will not block the waterproof zipper 4. The inside and upper inside of the water-blocking sleeve 5 are only in contact with the shoe body 1 and the shoe shaft 3. Therefore, before wearing, the user rolls up the water-blocking sleeve 5 downwards, similar to rolling up trouser legs. The difference from rolling up trouser legs is that the water-blocking sleeve 5 is rolled down while the trouser legs are usually rolled up upwards. After that, the user can pull down the waterproof zipper 4 to open the upper part of the outer surface of the shoe body 1 and the shoe shaft 3, so that the user can directly put the foot and lower leg wearing the shoes into the shoe body 1 and the shoe shaft 3, avoiding the shoes passing through the top of the shoe shaft 3 when wearing rain boots, which would cause mud and sand to transfer to the pants.
[0043] After putting on the rain boots, the user zips up the waterproof zipper 4. The waterproof zipper 4 has good closure and can effectively prevent water splashing, thus reducing the possibility of water entering the rain boots. Then, the user flips the water-blocking sleeve 5 upwards to make it stand upright, increasing the wading height of the rain boots and preventing water pressure in puddles from causing water to seep through the waterproof zipper 4 and into the boot body 1 and boot shaft 3. Then, the user tightens the first limiting rope 7 to make the top of the water-blocking sleeve 5 fit tightly against the boot shaft 3. The water-blocking sleeve 5 is made of TPU material, which has good elasticity and can fill gaps, thus preventing rainwater from accumulating in the gap between the water-blocking sleeve 5 and the boot body 1 and boot shaft 3. After the seepage phenomenon is detected, the first limiting rope 7 can be used to limit the contact pressure between the water-blocking sleeve 5 and the shoe shaft 3. Finally, the user tightens the second limiting rope 11 to make the sealing sleeve 9 fit snugly against the user's pants, preventing rainwater from entering from the top of the shoe shaft 3. The limiting method of the first limiting rope 7 and the second limiting rope 11 can be knotted, or a pig nose buckle can be added to change the knotting method to a pig nose buckle limiting method. It should be noted that the height of the water-blocking sleeve 5 is not limited to the height shown in the attached figure. The height of the water-blocking sleeve 5 can be further increased, for example, to contact the sealing sleeve 9, or the height of the water-blocking sleeve 5 can be set or reduced according to the height shown in the attached figure.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
