Description
Underarm anti-water double zipper raincoat structure Technical Field
[0001] This invention relates to a reverse-flow double-zipper raincoat structure, which refers to a raincoat body with an opening on at least one side near the armpit area of the sleeve and the front panel, and an outer cover. The outer cover has an outer zipper on its outer side, and an inner baffle is provided at the lower end of the outer cover. The inner zipper is positioned on the inner side in the opposite direction to the outer zipper. Prior Technology
[0002] Based on the commonly seen "side-opening double-zipper raincoat structure," such as the Republic of China No. M642913 (Application No. 12200856), its structure, combined with its diagrams and the content defined in the claims, can be roughly understood as follows: It includes a raincoat body with an opening from top to bottom on one shoulder side, featuring a first zipper. Inside the raincoat body, two extension panels extend to the left and right sides of the opening, extending towards the same side, with a second zipper located between the two sides away from the opening. However, upon inspection, the opening is V-shaped and located on one shoulder side, extending downwards. Its structure still has various deficiencies. The applicant analyzes this as follows: Because the opening is located at the front of the garment, when rainwater splashes from the front, it will enter through the first zipper. Although the left and right extension panels inside the opening, and the first and second zippers, are staggered, they form an N-shape when riding a bicycle in a seated position. This means that the first and second zippers of the side-opening double-zipper jacket are located in front of the body and on the upper thigh. Therefore, when rainwater hits the raincoat from the front, it first enters the left and right extension panels through the first zipper and accumulates inside them. Furthermore, because the second zipper is located near one shoulder of the raincoat body, and it forms an N-shape when riding a bicycle in a seated position, the accumulated water cannot drain immediately and instead enters the raincoat through the second zipper. This significantly reduces its practicality, which is something that manufacturers and consumers are eager to overcome. Summary of the Invention
[0003] To address the shortcomings of the existing technology, the main objective of this invention is to provide a raincoat structure with underarm anti-dampening double zippers, comprising a raincoat body, a collar at the top and sides, and sleeves at the bottom under the armpits. An opening is provided between at least one side of the front panel and the outer edge of the back panel near the underarm area of the sleeve. The opening has an outer cover with an external zipper opening on its outer side. An inner baffle forming a flow channel is provided inside the lower end of the outer cover. An inner opening with an inner zipper is provided between the inner edge of the lower end of the outer cover and the opening, thereby overcoming the difficulties of the existing technology.
[0004] The secondary objective of this invention is to provide a double-zippered raincoat structure with underarm drainage. It utilizes an external zipper located on one side of the outer cover and an internal zipper located on the lower end of the outer cover and positioned in the opposite direction to the external zipper for side drainage. Rainwater will not accumulate on the internal cover and will not flow into the raincoat body through the internal zipper.
[0005] Another objective of this invention is to provide a double-zippered raincoat structure with underarm waterproofing, which effectively improves its ease of use and allows rainwater to avoid the inner side of the inner flap and be contained within the inner opening of the zipper.
[0006] The problem this invention aims to solve is that, according to the commonly seen "side-opening double-zipper raincoat structure" on the market, such as the Republic of China's new type of evidence number: M642913, the opening is V-shaped and located on one shoulder, extending downwards from the front of the garment. When rainwater splashes from the front, it enters the left and right extensions inside the opening of the first zipper. When riding a bicycle, both the first and second zippers are located in front of the body and on the upper part of the thighs. Rainwater enters the left and right extensions through the first zipper and accumulates inside the left and right extensions. The accumulated water cannot drain out and enters the raincoat through the second zipper, greatly reducing its practicality.
[0007] To address the aforementioned objective, this invention provides a double-zippered raincoat structure with underarm drainage, comprising: a raincoat body including a front panel and a back panel joined together, with a collar and a sleeve formed at the upper end and sides respectively, and an underarm formed on the inner side of the lower end of the sleeve; characterized in that: The raincoat body has an opening at least one side of the front panel and the outer edge of the back panel near the armpit area of the sleeve. The opening connects to an outer cover of the front panel. An opening is formed between the outer cover and the outer edge of the back panel and has an outer zipper. The lower end of the outer cover has an inner baffle that serves as a flow channel. The upper end of the inner baffle is connected to the upper end of the outer cover and the front panel opposite the upper end of the opening. The outer side of the inner baffle connects to the outer edge of the back panel. The inner side of the inner baffle connects to an inner edge formed by the inner side of the lower end of the outer cover and has an inner opening with an inner zipper between it and the front panel connected to the opening. The outer zipper opens to the side and is positioned in the opposite direction to the inner zipper, serving as a side drain.
[0008] In this work, the opening is in the shape of a long U.
[0009] In this work, the outer cover and the inner baffle are rectangular.
[0010] In this invention, the width of the inner baffle is greater than or equal to the width of the outer cover.
[0011] In this invention, the length of the inner baffle is greater than or equal to the length of the outer cover.
[0012] Compared with the effects of prior art, this invention includes a raincoat body, with a collar at the top and sides and sleeves at the bottom with armpits. At least one side of the front panel of the raincoat body and the outer edge of the back panel have an opening near the armpit area of the sleeve. The opening has an outer cover with an opening for an outer zipper on its outer side. The lower end of the outer cover has an inner baffle serving as a flow channel. The inner side of the inner baffle connects to the inner edge of the lower end of the outer cover and is connected to the opening between the front panel and the inner side of the outer cover. The opening includes an inner zipper; thus, by utilizing the side-opening outer zipper located on one side of the outer cover and the inner zipper located at the lower end of the outer cover and positioned in the opposite direction to the outer zipper, rainwater is diverted and drained from the side. Rainwater will not accumulate on the inner baffle or flow into the interior of the raincoat body through the inner zipper; this effectively improves its ease of use and allows rainwater to avoid the inner zipper located inside the inner opening on the inner side of the inner baffle, meeting the needs of progress, practicality, and users, demonstrating its significant benefits.

[0015] Please refer to Figures 1, 2, 3, 4, and 5, which are exploded perspective views, assembled perspective views, assembled sectional views, and embodiments of the invention with the outer zipper on the outside and the inner zipper on the inside of the inner support plate when worn in a riding posture. Also shown are embodiments of the invention where rainwater enters the inner support plate through the outer zipper and flows laterally, avoiding the zipper located at the lower end of the outer cover plate and positioned in the opposite direction within the inner support plate. In a preferred embodiment, the underarm anti-water double zipper raincoat structure of this invention includes a raincoat body 1, comprising a front piece 11 and a back piece 12 joined together, with a collar 10 and a sleeve 13 formed at the upper end and sides respectively. An underarm 131 is formed on the inner side of the lower end of the sleeve 13. Its characteristics are: The raincoat body 1 has an opening 15 on at least one side of the front piece 11 and the outer edge of the back piece 12, located near the armpit 131 area of the sleeve 13. An outer cover 14 is connected to the front piece 11 via the opening 15. An opening 1412 is formed between the outer cover 14 and the outer edge of the back piece 12, and an outer zipper 151 is provided. An inner baffle 16, serving as a flow channel, is provided inside the lower end of the outer cover 14. The upper end of the inner baffle 16 is connected to the upper end of the outer cover 14 and the front piece 11 opposite the upper end of the opening 15. The outer side of the inner baffle 16 is connected to the outer edge of the back piece 12, and the inner side of the inner baffle 16 is connected to the inner side of the lower end of the outer cover 14. An inner opening 1116 is provided between the inner edge 141 and the front piece 11 connected to the opening 15, and an inner zipper 161 is provided (as shown in the first, second, and third figures); the outer zipper 151 is side-opening and is arranged in the opposite direction to the inner zipper 161 to guide the flow on the side (as shown in the fourth and fifth figures); the opening 15 of this invention is U-shaped, but this does not limit this invention; the outer cover 14 and the inner baffle 16 are rectangular, but this does not limit this invention; the width of the inner baffle 16 is greater than or equal to the width of the outer cover 14; the length of the inner baffle 16 is greater than or equal to the length of the outer cover 14.
[0016] Please refer to Figures 4 and 5. In this invention, the inner zipper 161 is positioned on the outer edge of the back panel 12 of the raincoat body 1 and covers the inner edge 141 of the outer cover 14 located at its lower inner side. The outer zipper 151 is located near the armpit area 131 of the sleeve 13 of the raincoat body 1, and is situated on the outer edge of the back panel 12 and the outer side of the outer cover 14. That is, the outer zipper 151 is side-opening on the front panel 11 of the raincoat body 1, near the armpit area 131 of the sleeve 13. This prevents rainwater from flowing into the interior of the raincoat body 1 even if it enters the outer zipper 151 and reaches the inner baffle 16, which acts as a flow channel. The outer zipper 151 is not front-opening, because a front opening would allow... The outer zipper 151 is designed to prevent water from entering. Its placement is not intended to avoid rainwater, but rather to allow rainwater to enter the inner flap 16 via the outer zipper 151. When wearing the raincoat while cycling, the raincoat body 1 will form an "N" shape, and the outer zipper 151 will be located on the side of the raincoat body 1 (i.e., the outer thigh), making the inner flap 16 more inclined for faster drainage. The inner zipper 161 is located on the inner edge 141 at the lower end of the outer flap 14 and is covered by the outer flap 14. After rainwater enters the outer zipper 151, because the outer zipper 151 is side-opening, rainwater continues to enter the inner flap 16 and flow laterally. If the outer zipper 151 is open... Rainwater flows to the left if the opening is on the left side of the raincoat body 1, and to the right if the opening is on the right side. The inner zipper 161, located on the inner panel 16 and connected to the front panel 11 at the opening 15, is positioned in the opposite direction to the side-opening outer zipper 151. This arrangement utilizes physical logic to guide rainwater to the side through the inner panel 16. Combined with the reverse orientation of the inner panel 16 and the outer zipper 151, the double zipper structure of the outer zipper 151 and inner zipper 161 avoids the natural flow of rainwater. Furthermore, the outer zipper 151 is positioned near the armpit area 131, preventing rainwater from entering through the outer zipper 151. The inner zipper 161 flows smoothly into the interior of the raincoat body 1. When this invention is in use, the direction / path guidance of rainwater flow is achieved through the inner baffle 16 located inside the outer cover 14. The outer zipper 151 is located on the side, and the inner zipper 161 is located in the middle of the raincoat body 1 and inside the lower end of the outer cover 14. Rainwater entering the raincoat body 1 will be guided by the inner baffle 16, which bends and tilts from the inside to the outside when riding. The rainwater will remain on the outer side of the rider's thigh and will not enter the interior of the raincoat body 1. In other words, this invention has an advantage in guiding the flow of water during riding posture. The placement of the inner baffle 16 will quickly drain the rainwater laterally when the wearer is riding.
[0017] This invention includes a raincoat body 1, with a collar 10 at the top and sides, and sleeves 13 with armpits 131 at the bottom. At least one side of the front panel 11 of the raincoat body 1 and the outer edge of the back panel 12 are provided with an opening 15 near the armpit area 131 of the sleeves 13. The opening 15 has an outer cover 14 with an opening 1412 on its outer side, featuring an outer zipper 151. The lower end of the outer cover 14 has an inner baffle 16 serving as a flow channel. The inner side of the inner baffle 16 connects to the inner edge 141 of the lower end of the outer cover 14 and is connected to the opening 15 between the front panel 11 and the inner opening. 1116 and has the inner zipper 161; thereby achieving the following: by using the outer zipper 151 that is side-opening on one side of the outer cover 14, and the inner zipper 161 that is located at the lower end of the outer cover 14 and is arranged in the opposite direction to the outer zipper 151 for side drainage, rainwater will not accumulate in the inner baffle 16 and will not flow into the interior of the raincoat body 1 through the inner zipper 161; effectively improving its ease of use, and allowing rainwater to avoid the inner zipper 161 located inside the inner opening 1116 on the inner side of the inner baffle 16, meeting the needs of progress, practicality and users, and demonstrating its benefits.
