Dual-purpose raincoat with waterproofing

Abstract

This utility model relates to a dual-purpose raincoat that is waterproof. The first and second rain-blocking straps are fixed to the outer sides of the window, respectively, with buckle assemblies on their opposite sides. When the straps are folded and fastened, they overlap and cover the window, forming a continuous waterproof layer that directly prevents rainwater from seeping into the inner side of the raincoat through the window. Simultaneously, adjacent sides of the folded straps are tightly connected by a sealing structure (such as a heat-pressed sealing strip or waterproof adhesive strip), effectively sealing side gaps and completely solving the problem of rainwater seeping in from the edges due to insufficient side sealing in traditional rain-blocking straps. This design, while simplifying operation, significantly improves the waterproof reliability of the window area through the synergistic effect of buckle fixing and side sealing, ensuring that the rain cap does not get wet when retracted to the inner side, thus achieving long-lasting waterproof protection in dual-purpose raincoat scenarios.

Technical Field

[0001] This utility model relates to the field of raincoat technology, and in particular to a dual-purpose raincoat that is waterproof and suitable for use while riding or covering electric vehicles, bicycles and other similar vehicles. Background Technology

[0002] When traditional dual-purpose raincoats cover vehicles, rainwater easily seeps into the inside through the opening mechanism at the window, causing the rain cap to become wet. Although existing technologies cover the window with rain guards, the side seal is insufficient, and rainwater can still seep in from the edges of the guards. To address this, this invention proposes an optimized solution that solves the side leakage problem through the synergistic action of buckles and a sealing structure. Utility Model Content

[0003] The core of this invention lies in the improvement of the rainproof belt structure: a buckle assembly is provided on the opposite sides of the first and second belt bodies, which is fixed by the buckle after folding, and combined with the side sealing structure to form an all-round waterproof barrier, solving the problem of side water seepage. The principle is described in detail below with reference to specific embodiments.

[0004] A dual-purpose raincoat that is waterproof includes:

[0005] The raincoat body has an inner side and an outer side. The raincoat body has a window that extends through the inner side and the outer side. The window has an opening and closing component on the side where the outer side is located. The opening and closing component can open or close the window.

[0006] A rain cap, connected to the edge of the window, which can extend out to the outer side or retract to the inner side through the open window;

[0007] The rainproof strip includes a first strip and a second strip, which are respectively fixed to the outer side and located on opposite sides of the window. Each of the first and second strips has a buckle assembly on its opposite side. The first and second strips can be folded relative to the raincoat body, allowing the buckle assemblies to engage and overlap, covering the window area. Adjacent sides of the folded first and second strips are connected by a sealing structure to prevent rainwater from seeping in from the sides.

[0008] In one embodiment, the buckle assembly includes a first male buckle disposed on the opposite side of the first strap body and a first female buckle disposed on the opposite side of the second strap body. After the first male buckle and the first female buckle are fastened together, a waterproof layer continuously covering the window is formed on the surfaces of the first strap body and the second strap body.

[0009] In one embodiment, the buckle assembly further includes a second male buckle and a second female buckle, the first male buckle and the second male buckle are arranged at intervals along the length direction of the first belt body, the first female buckle and the second female buckle are arranged at intervals along the length direction of the second belt body, and the buckling position of the second male buckle and the second female buckle is located outside the buckling position of the first male buckle and the first female buckle, forming a double waterproof barrier.

[0010] In one embodiment, the sealing structure is a hot-pressed sealing strip, a waterproof strip, or an ultrasonically welded structure, which is continuously arranged along the adjacent sides after the first and second belts are folded.

[0011] In one embodiment, the opposite surfaces of the first and second straps are coated with a hydrophobic coating, which at least covers the fastening area of ​​the snap-fit ​​assembly and / or the seam of the sealing structure.

[0012] In one embodiment, the zipper is a two-way waterproof zipper, and an elastic sealing strip is embedded between the teeth of the zipper, the elastic sealing strip filling the gap between the teeth when the zipper is closed.

[0013] In one embodiment, the rainproof strip and the raincoat body are integrally formed by high-frequency welding, and the folding area of ​​the rainproof strip has a pre-set crease line, and the crease line is covered with a flexible waterproof membrane.

[0014] In one embodiment, the edge of the rain cap is provided with an adjustable elastic band, which is fixed to the edge of the window by a hidden Velcro fastener, and the hook side and the loop side of the Velcro fastener are respectively embedded in the interlayer of the rain cap and the window.

[0015] In one embodiment, the first and second straps are embedded with memory metal wires, which are distributed along the folding path of the straps so that the straps automatically conform to the outer surface of the raincoat body after folding.

[0016] In one embodiment, a waterproof lining is provided on the inner side of the raincoat body corresponding to the position of the window. The edge of the waterproof lining is sealed to the edge of the window with waterproof adhesive, and the waterproof lining is used to store the rain cap that is retracted to the inner side.

[0017] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0018] This design significantly improves the waterproof performance of traditional raincoats. The first and second sections of the rain guard are fixed to the outer sides of the window, with buckle components on their opposite sides. When the sections are folded and fastened, they overlap and cover the window, forming a continuous waterproof layer that directly prevents rainwater from seeping into the inner side of the raincoat through the window. Simultaneously, adjacent sides of the folded sections are tightly connected by a sealing structure (such as a heat-pressed sealing strip or waterproof adhesive strip), effectively sealing side gaps and completely solving the problem of rainwater seeping in from the edges due to insufficient side sealing in traditional rain guards. This design, while simplifying operation, significantly improves the waterproof reliability of the window area through the synergistic effect of buckle fixing and side sealing, ensuring that the rain cap remains dry when retracted to the inner side, thus achieving long-lasting waterproof protection for dual-use raincoats.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] Please refer to the following first. Figures 1 to 4This utility model provides a waterproof dual-purpose raincoat 10, which can be worn alone to protect the body from rain, or used to protect both the vehicle and the body from rain while riding a bicycle, or placed on the vehicle for separate rain protection. The waterproof dual-purpose raincoat 10 includes a raincoat body 100, a rain hood 200, and rainproof straps 300. The raincoat body 100 has opposing outer sides 120 and inner sides 110. The raincoat body 100 has a window 130 that extends through both the outer side 120 and the inner side 110. An opening / closing element 140 is provided on the outer side 120 to open or close the window 130. The rain hood 200 is worn on the head and is connected to the edge of the window 130. When the window 130 is open, the rain hood 200 can extend through the window 130 to the side of the outer side 120 or retract to the side of the inner side 110. The rainproof straps 300 include a first strap body 310 and a second strap body 320. The first strap 310 and the second strap 320 are respectively disposed on the outer side 120 and located on opposite sides of the window 130. The opposite sides of the first strap 310 and the second strap 320 are respectively provided with buckle components 330. The first strap 310 and the second strap 320 can be folded relative to the raincoat body 100 so that the buckle components 330 can be fastened to overlap and cover the first strap 310 and the second strap 320 at the window 130 position. This allows the first strap 310 and the second strap 320 to block rainwater from the opposite two outer surfaces of the two straps, thus solving the problem that rainwater will enter the inner side 110 of the raincoat body 100 through the window 130 from the opposite two outer surfaces of the two straps, causing the rain cap 200 to get wet and the waterproof effect to be poor. Furthermore, the sides of the first belt 310 and the second belt 320 are sealed together. Specifically, the adjacent sides of the first belt 310 and the second belt 320 after folding are connected by a sealing structure 340. The sealing structure 340 can be a heat-pressed sealing strip, a waterproof strip, or an ultrasonically welded structure, and is continuously provided along the adjacent sides of the first belt 310 and the second belt 320 after folding. The sealing structure 340 can prevent rainwater from seeping in from the side, further improving the waterproof effect and solving the problem of rainwater entering the inner side 110 of the raincoat body 100 from both sides where the two belts are connected through the window 130. Thus, the two belts of this solution can block rainwater from all angles after being stacked.

[0032] refer to Figure 2 and Figure 3The buckle assembly 330 includes a first male buckle 311 and a second male buckle 312 disposed on the opposite side of the first belt body 310, and a first female buckle 321 and a second female buckle 322 disposed on the opposite side of the second belt body 320. The first male buckle 311 and the second male buckle 312 are arranged at intervals along the length direction of the first belt body 310, and the first female buckle 321 and the second female buckle 322 are arranged at intervals along the length direction of the second belt body 320. After the first male buckle 311 and the first female buckle 321 are fastened together, and the second male buckle 312 and the second female buckle 322 are fastened together, a waterproof layer continuously covering the window 130 is formed on the surfaces of the first belt body 310 and the second belt body 320. The fastening position of the second male buckle 312 and the second female buckle 322 is located outside the fastening position of the first male buckle 311 and the first female buckle 321, forming a double waterproof barrier to ensure that the two belt bodies are securely joined. Specifically, the number of male and female buckles can be set to multiple side by side as needed, for example... Figure 2 The illustration shows that each male and female buckle is set in a row of three. Of course, the number of male and female buckles in other embodiments can be customized according to the user's needs. It should be noted that in other embodiments, one of the mating male and female buckles can be omitted. For example, the second male buckle 312 and the second female buckle 322 can be removed. In this case, the two belts can still be implemented by only mating the first male buckle 311 and the first female buckle 321, so that the surfaces of the first belt body 310 and the second belt body 320 form a continuous waterproof layer covering the window 130.

[0033] In one embodiment, the opposite surfaces of the first belt body 310 and the second belt body 320 are coated with a hydrophobic coating, which at least covers the fastening area of ​​the snap-fit ​​assembly 330 and / or the joint of the sealing structure 340. That is, the hydrophobic coating may only cover the fastening area of ​​the snap-fit ​​assembly 330, or only cover the joint of the sealing structure 340, or cover both the fastening area of ​​the snap-fit ​​assembly 330 and the joint of the sealing structure 340. Since the sealing performance of the fastening area or joint may be poor, this design can effectively improve the leakage problem caused by poor sealing in the fastening area or joint area. The hydrophobic coating uses a fluorocarbon resin material, making it difficult for water droplets to adhere and causing them to roll off quickly. Experiments show that the coating can maintain a hydrophobic efficiency of over 90% even in heavy rain, significantly reducing the risk of water seepage.

[0034] In one embodiment, the opening / closing component 140 is a two-way waterproof zipper with an elastic sealing strip embedded between the zipper teeth. This elastic sealing strip fills the gaps between the teeth when the zipper is closed. This design improves waterproofing even if the window 130 is not completely covered by the two straps. When the zipper is closed, the sealing strip expands under pressure, filling the gaps between the teeth and completely preventing rainwater from seeping in through the zipper seams. The zipper's sliding head is designed in an arc shape to avoid interference with the folding part of the rainproof strip, ensuring smooth operation.

[0035] In one embodiment, the rainproof belt 300 and the raincoat body 100 are integrally formed by high-frequency welding. There are no pinholes at the weld, which prevents leakage. The folding area of ​​the rainproof belt 300 is pre-set with crease lines. The crease lines guide the belt to fold along a fixed path, reducing material fatigue caused by repeated use. The crease lines are covered with a flexible waterproof membrane, which prevents micro-cracks from forming at the creases due to bending.

[0036] In one embodiment, reference Figure 3 and Figure 4 An adjustable elastic band 210 is sewn along the edge of the rain cap 200, and the end of the elastic band 210 is secured to the edge of the window 130 via a concealed Velcro 220. The hook side 211 of the Velcro 220 is embedded in the layer of the rain cap 200, and the rough side 212 is sewn into the inside of the window 130 to prevent it from being exposed and affecting waterproofing. With this design, the elastic band 210 can secure the rain cap 200 when it is tucked inside the window 130.

[0037] In one embodiment, the first strap 310 and the second strap 320 are embedded with shape memory metal wires distributed along the folding path of the straps, so that the straps automatically conform to the outer surface of the raincoat body 100 after folding. For example, in a specific embodiment, the first strap 310 and the second strap 320 are embedded with nickel-titanium alloy shape memory metal wires distributed along the folding path. When the straps are folded, the shape memory metal wires are triggered by body temperature or ambient temperature, automatically restoring a preset bending shape, so that the straps fit tightly to the outer surface of the raincoat body 100. This design is particularly suitable for low-temperature environments, avoiding poor adhesion caused by material hardening.

[0038] In one embodiment, reference Figure 3 A waterproof lining 150 is provided on the inner side of the raincoat body 100 corresponding to the window 130. The edge of the waterproof lining 150 is sealed to the edge of the window 130 with waterproof adhesive, and the waterproof lining 150 is used to store the rain hood 200 when it is retracted to the inner side. When the rain hood 200 is retracted, it can be folded and stored inside the waterproof lining 150. The three-dimensional structure of the lining provides a protective space for the rain hood 200, preventing it from being squeezed and deformed. The lining is made of TPU-coated fabric, which combines flexibility and complete waterproofness.

[0039] This design significantly improves the waterproof performance of traditional raincoats. The first strap 310 and the second strap 320 of the rainproof belt 300 are fixed to the outer sides 120 of the window 130 on both sides, with buckle components 330 on their opposite sides. When the straps are folded and fastened, they overlap and cover the window 130, forming a continuous waterproof layer that directly prevents rainwater from seeping into the inner side 110 of the raincoat 10 through the window 130. At the same time, the adjacent sides of the folded straps are tightly connected by a sealing structure 140 (such as a heat-pressed sealing strip or a waterproof strip), effectively sealing the side gaps and completely solving the problem of rainwater seeping in from the edges due to insufficient side sealing in traditional rainproof belts 300. This design, while simplifying operation, significantly improves the waterproof reliability of the window 130 area through the synergistic effect of buckle fixing and side sealing, ensuring that the rain cap 200 is not wet when retracted to the inner side 110, thus achieving long-term waterproof protection for the raincoat 10 in dual-use scenarios.

Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
