Description

Technical Field

[0001] This application relates to the technical field of down jacket zippers, and in particular to a seamless zipper structure for down jackets. Background Technology

[0002] Down jackets, as essential winter garments for warmth, rely heavily on the performance of their zipper structure to determine their overall quality. In the current down jacket market, traditional zipper structures have certain drawbacks. From a warmth perspective, traditional zippers are typically attached to the down jacket fabric via stitching, inevitably creating tiny gaps between the zipper and the fabric. In cold environments, these gaps become channels for cold air to enter, significantly reducing the down jacket's warmth. Utility Model Content

[0003] To address the problems mentioned in the background art, this application provides a seamless zipper structure for down jackets.

[0004] The seamless zipper structure for down jackets provided in this application adopts the following technical solution:

[0005] A seamless zipper structure for down jackets, comprising:

[0006] A zipper body, wherein a zipper pull is provided on the zipper body;

[0007] A sealing strip is provided at the connection between the zipper body and the down jacket fabric.

[0008] Connecting strips are provided on both sides of the zipper body. The connecting strips are used to install the zipper body on the down jacket. Several connecting holes are evenly distributed on the connecting strips.

[0009] A protective layer that covers the surface of the zipper body.

[0010] Preferably, the bottom of the zipper body is provided with an anti-slip plate.

[0011] Preferably, the pull head is provided with a non-slip handle.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] Compared to existing technologies, this design, with its sealing strips and protective layers, effectively solves the problems of air and water leakage associated with traditional zippers, significantly improving the warmth and waterproofness of down jackets. The connecting strips prevent exposed seams, making the down jacket look smoother and more aesthetically pleasing. The anti-slip handles and anti-slip tabs enhance the durability, ease of use, and safety of the zipper, thus improving the overall quality of the down jacket. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0018] This application discloses a seamless zipper structure for down jackets. (Refer to...) Figure 1-2 A seamless zipper structure for down jackets mainly includes a zipper body 1, a sealing strip 4, a connecting strip 7, and a protective layer 6.

[0019] The zipper body 1 is equipped with a zipper pull 2. The zipper body 1 adopts a flat and smooth design with closely arranged chain teeth to ensure smooth opening and closing. The zipper body 1 is made of high-strength, wear-resistant metal to ensure its durability.

[0020] The sealing strip 4 is set at the connection between the zipper body 1 and the down jacket fabric. It is made of highly elastic and waterproof rubber. The sealing strip 4 is tightly bonded to the zipper body 1 and the down jacket fabric through a special hot pressing process to form a seamless sealing structure, which effectively prevents the intrusion of cold air and rainwater and improves the warmth and waterproofness of the down jacket.

[0021] Both sides of the zipper body 1 are provided with connecting strips 7. The connecting strips 7 are used to securely install the zipper body 1 onto the down jacket. Several connecting holes 8 are evenly distributed on the connecting strips 7. Heat-fusion connection points are set on the down jacket fabric at the positions corresponding to the connecting holes 8. The connecting strips 7 are firmly connected to the fabric through the heat-fusion process. This connection method is not only strong and reliable, but also avoids the gap problem caused by traditional stitching.

[0022] The protective layer 6 covers the surface of the zipper body 1 and is made of a thin, soft, and abrasion-resistant waterproof fabric. The edge of the protective layer 6 is connected to the down jacket fabric through seamless splicing technology, which further enhances the waterproof performance and protects the zipper body 1 from external friction and damage, thus extending the service life of the zipper.

[0023] The bottom of the zipper body 1 is provided with an anti-detachment baffle 5. The anti-detachment baffle 5 is integrally formed with the zipper body 1, which can effectively prevent the zipper pull 2 ​​from falling off the zipper body 1 during use and improve the safety of use.

[0024] The zipper body 1 has a non-slip handle 3 at the zipper head 2, which makes it easy for users to operate the zipper even when wearing gloves, thus improving the ease of use.

[0025] The implementation principle of a seamless zipper structure for down jackets according to an embodiment of this application is as follows: When manufacturing the down jacket, firstly, the connecting strip 7 of the zipper body 1 is connected to the down jacket fabric using a hot-melt process to ensure a tight bond between the connecting strip 7 and the down jacket fabric, guaranteeing that the zipper body 1 is securely installed on the down jacket. Then, a sealing strip 4 is installed at the connection between the zipper body 1 and the down jacket fabric. The contact surface of the sealing strip 4 is aligned with both the zipper body 1 and the down jacket fabric. Through a hot-pressing process, the sealing strip 4 is firmly bonded between the two, forming a seamless seal. Next, a protective layer 6 is installed, covering the surface of the zipper body 1. Its edges are connected to the down jacket fabric using seamless splicing technology, such as ultrasonic welding, to ensure that the protective layer 6 is tightly connected to the down jacket fabric, enhancing waterproof performance.

[0026] During daily use, when the zipper needs to be opened or closed, the user pulls the zipper using the anti-slip handle 3 at the zipper head 2. During the opening and closing of the zipper, the chain teeth of the zipper body 1 fit together tightly to ensure smooth operation. Due to the presence of the sealing strip 4 and the protective layer 6, cold air and rainwater cannot penetrate into the down jacket.

[0027] Regularly check the condition of the zipper, and check whether the sealing strip 4 has shifted or the protective layer 6 is damaged. If any problems are found, repair or replace the corresponding parts in time to ensure the normal function of the zipper structure and the performance of the down jacket.

[0028] When washing down jackets, choose a gentle washing method and avoid excessive pulling on the zipper to prevent the connecting strip 7 from loosening or the zipper body 1 from being damaged.

[0029] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
