Description

Technical Field

[0001] This application relates to the field of zipper technology, and in particular to an anti-snagging zipper and zipper products. Background Technology

[0002] With the rapid changes in clothing today, lightweight down jackets, skin-friendly clothing, and fleece clothing have been developed in recent years. Due to the excessive softness of the fabric, zippers often get stuck on the fabric or lining. If you pull hard, you may tear the fabric or lining or even damage the garment.

[0003] Currently, some manufacturers use a blocking strip sewn between the fabric and the tape. The end of the blocking strip has a raised structure located between the fabric and the zipper pull seam, which prevents external fabric from entering the seam and thus prevents fabric jamming. However, during the sewing process, there is no fixed positional relationship between the blocking strip and the tape, which can easily lead to the blocking strip shifting during sewing, affecting the protective function of the raised structure. Furthermore, when the blocking strip is sewn on both sides of the tape, it needs to be sewn on both sides sequentially, affecting sewing efficiency.

[0004] Therefore, ensuring the positioning effect and sewing efficiency of the blocking strip is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide an anti-jamming zipper and zipper product, which allows the blocking strip to be clamped on the edge of the fabric strip, and the blocking strip is limited by a U-shaped structure, so as to ensure the positioning effect of the blocking strip and the sewing efficiency.

[0006] To achieve the above objectives, this application provides an anti-snagging edge zipper, comprising:

[0007] The fabric belt has teeth and a sliding zipper fixed to it;

[0008] The blocking tape includes a sub-tape and a mother tape integrally connected to both ends of the sub-tape. The thickness of the mother tape is greater than that of the sub-tape. The sub-tape has a U-shaped structure that covers the outer edge of the fabric tape, and the inner wall of its U-shaped structure is tightly fitted to the side and side edge of the fabric tape.

[0009] A sewn fabric is fixedly attached to the outer wall of the sub-belt. The main belt is located between the zipper head and the sewn fabric, and the thickness of the main belt is greater than the thickness of the sewn fabric to form an anti-jamming structure.

[0010] Optionally, the mother tape has an arcuate outer surface on at least the side facing the pull head.

[0011] Optionally, the sewn fabric, sub-belt, and cloth strip are sewn together with a stitch, and the stitch passes sequentially through one of the sewn fabrics, the first U-shaped wall of the sub-belt, the cloth strip, the second U-shaped wall of the sub-belt, and the other sewn fabric.

[0012] Optionally, the stitch is located at one end of the sub-tape closer to the mother tape.

[0013] Optionally, the main tape has a columnar structure, and a space is formed between the sewn fabric and the zipper head to accommodate the flipping of the main tape.

[0014] Optionally, the master tape has a tendency to flip towards the chain teeth in the initial state, and the sliding pull head is used to drive the master tape to flip away from the chain teeth.

[0015] Optionally, after the pull head drives the main tape to flip, the maximum vertical distance between the outer surface of the main tape and the fabric tape is greater than the maximum vertical distance between the sewn fabric and the fabric tape.

[0016] Optionally, the blocking strip extends along the length of the fabric strip, and the extension length corresponds at least to the sliding range of the pull head.

[0017] Optionally, the inner or outer side of the master tape is provided with a pattern.

[0018] A zipper product comprising the anti-snagging edge zipper described in any one of the above claims.

[0019] The beneficial effects of this application are as follows: by folding the blocking tape in half to form a U-shaped structure that is clamped on the outer edge of the fabric tape, and with a mother tape at both ends of the U-shaped structure, the mother tape is located between the zipper head and the sewing fabric. The larger mother tape forms a blocking structure between the zipper head fabric seam and the sewing fabric, preventing the sewing fabric from entering the zipper head fabric seam or inner cavity, thereby playing an anti-jamming role; and by utilizing the inner wall surface of the U-shaped structure of the sub-tape to fit tightly against the side and side edge of the fabric tape, the blocking tape is subject to a certain limiting effect on the fabric tape, avoiding the sub-tape from shifting during the sewing process, ensuring the positioning accuracy of the blocking tape, ensuring sewing efficiency and the effective blocking effect of the blocking tape.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper," "lower," "front," and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 and Figure 2 As shown, in this embodiment, an anti-jamming zipper is provided, including a fabric strip 1, a blocking strip 2, and a sewn fabric 3. The fabric strip 1 is fixedly provided with a zipper tooth 6 and a slidable zipper head 5. The blocking strip 2 includes a sub-strip 21 and a mother strip 22 integrally connected to both ends of the sub-strip 21. The thickness of the mother strip 22 is greater than that of the sub-strip 21, so that the mother strip 22 forms a bulging structure protruding from the sub-strip 21 in the thickness direction. The sub-strip 21 has a certain length and width. By folding the sub-strip 21, the sub-strip 21 forms a U-shaped structure covering the outer edge of the fabric strip 1. Here, the outer edge of the fabric strip 1 refers to the side of the fabric strip 1 opposite to the side where the zipper tooth 6 is located.

[0029] During the formation of the U-shaped structure of the sub-belt 21, the mother belts 22 at both ends will move closer to each other, so that the mother belts 22 are located on two opposite sides of the fabric belt 1 respectively; and when the sub-belt 21 covers the fabric belt 1, the inner wall of the U-shaped structure of the sub-belt 21 can fit tightly with the side and edge of the fabric belt 1, so that the fabric belt 1 can play a certain limiting role for the sub-belt 21, improve the positioning accuracy of the sub-belt 21 on the fabric belt 1, and avoid easy deviation during the sewing process.

[0030] Alternatively, as a whole structure, the U-shaped structure of the sub-belt 21 can significantly increase the contact area between the blocking belt 2 and the cloth belt 1, thus improving the overall friction between the two, thereby enhancing the stability of the blocking belt 2 relative to the cloth belt 1 and ensuring the positioning effect of the blocking belt 2.

[0031] Furthermore, the main tape 22 can only be positioned in the effective blocking area when the blocking band 2 is stably set. Therefore, the blocking effect of the main tape 22 can be guaranteed by the above method.

[0032] The sewn fabric 3 is fixedly attached to the outer wall of the sub-belt 21. Based on the fixed connection of the sewn fabric 3, the blocking belt 2, and the fabric belt 1, the mother belt 22 can protrude from the sewn fabric 3 and is located between the zipper head 5 and the sewn fabric 3. The thickness of the mother belt 22 is greater than the thickness of the sewn fabric 3, thereby preventing the sewn fabric 3 from crossing the mother belt 22 and entering the fabric seam of the zipper head 5, forming an anti-jamming structure to prevent the fabric from jamming the zipper head 5.

[0033] In summary, this application folds the blocking tape 2 in half to form a U-shaped structure that clamps the outer edge of the fabric tape 1. The U-shaped structure has mother tapes 22 at both ends, located between the zipper pull 5 and the sewing fabric 3. The larger mother tape 22 forms a blocking structure between the zipper pull 5's fabric seam and the sewing fabric 3, preventing the sewing fabric 3 from entering the zipper pull 5's fabric seam or inner cavity, thus preventing jamming. Furthermore, the inner wall of the U-shaped structure of the sub-tape 21 is tightly fitted to the side and edge of the fabric tape 1, ensuring the blocking tape 2 is positioned within the fabric tape 1, preventing the sub-tape 21 from shifting during sewing, guaranteeing the positioning accuracy of the blocking tape 2, and ensuring sewing efficiency and the effective blocking effect of the blocking tape 2.

[0034] Furthermore, considering that the side of the female tape 22 facing the pull head 5 may need to come into contact with the pull head 5, in order to avoid the female tape 22 and the pull head 5 getting stuck, in this embodiment, the female tape 22 is provided with an arc-shaped outer surface at least on the side facing the pull head 5. The arc-shaped outer surface can be used to improve the smoothness of the pull head 5 and avoid the pull head 5 and the female tape 22 getting stuck.

[0035] Since the sub-belt 21 and the two mother belts 22 are an integral structure, the fabric 3, sub-belt 21 and fabric 1 can be sewn together sequentially by a single thread 4, based on the U-shaped structure of the sub-belt 21 holding the fabric 1. Specifically, during the sewing process, the thread 4 can pass through one sewing fabric 3, the first U-shaped wall of the sub-belt 21, the fabric 1, the second U-shaped wall of the sub-belt 21, and the other sewing fabric 3 in sequence. Since the sub-belt 21 is also restricted by the fabric 1, only one set of threads 4 is needed to achieve accurate positioning of the blocking belt 2. Compared with the traditional method of sewing at least at both ends of the blocking belt 2, this application can obviously simplify the sewing process while ensuring the sewing effect, making sewing more convenient and positioning more accurate.

[0036] Furthermore, the stitch 4 can be located at the end of the sub-belt 21 near the mother belt 22, or in other words, the stitch 4 can be located at the end of the sub-belt 21 away from its U-shaped bottom. Since the U-shaped structure is restricted by the fabric belt 1, it is only necessary to ensure that the opening of the U-shaped structure is stably connected to the fabric belt 1. Then the bottom of the U-shaped structure can be stably set under the restriction of the fabric belt 1.

[0037] At the same time, placing the stitch 4 at the end of the sub-belt 21 close to the main belt 22 can also improve the stability of the main belt 22, so that the main belt 22 will not shake randomly between the pull head 5 and the sewn fabric 3, thus ensuring the anti-jamming effect of the main belt 22.

[0038] Furthermore, depending on the characteristics of the garment fabric, the main tape 22 can be made of core-spun thread or with added thin cord. The shape of the main tape 22 can be various, such as ellipse, cylinder, cuboid, etc., without much restriction here. In some embodiments, the main tape 22 can be set as a columnar structure or a structure approximately columnar. Since the sewing fabric 3 is sewn on the sub-tape 21, the use of a columnar structure for the main tape 22 can facilitate the main tape 22 to flip in the space formed between the sewing fabric 3 and the pull head 5.

[0039] Based on this, the main tape 22 initially tends to flip towards the chain tooth 6. That is, when the stitch 4 is sewn, the main tape 22 should be close to the chain tooth 6, thus maintaining the initial state of the main tape 22 leaning towards the chain tooth 6. The main tape 22 can cover the chain tooth 6 to a certain extent, thereby protecting the chain tooth 6. When the zipper head 5 slides on the fabric tape 1, it will drive the main tape 22 at the corresponding position to flip away from the chain tooth 6, thereby ensuring that the zipper head 5 can slide naturally, which is both smooth and prevents the sewn fabric 3 from blocking the zipper head 5.

[0040] In addition, a logo pattern can be customized on the mother and daughter tapes 22. When sewing the logo pattern, it can be sewn on the outer surface of the mother tape 22, such as on the outside or inside of the mother tape 22. When sewn on the inside, it will not be completely covered because the mother tape 22 can be flipped, and it can be seen by flipping it.

[0041] It should be noted that after the pull head 5 drives the female belt 22 to flip, the pull head 5 is now positioned corresponding to the flipping position of the female belt 22. Please refer to... Figure 1 At this time, the maximum vertical distance H2 between the outer surface of the main tape 22 and the fabric tape 1 is greater than the maximum vertical distance H1 between the sewn fabric 3 and the fabric tape 1, thus ensuring that even if there is instability such as bending or folding at the fabric tape 1, the sewn fabric 3 cannot reach the seam of the pull head 5, ensuring the anti-jamming effect of the main tape 22.

[0042] Please refer to Figure 2 The blocking strip 2 extends along the length of the fabric strip 1. The length direction refers to the sliding direction of the zipper head 5. The extension length of the blocking strip 2 corresponds to at least the sliding range of the zipper head 5, thereby ensuring that no matter where the zipper head 5 slides, there is a corresponding mother strip 22 to ensure the overall anti-jamming effect of the zipper.

[0043] In addition, in order to improve the relative stability of the blocking tape 2 and the fabric tape 1 and ensure the positioning accuracy of the two during the sewing process, in some embodiments, anti-slip textures can be provided on the inner wall of the U-shaped structure of the sub-tape 21, thereby increasing the friction between the sub-tape 21 and the fabric tape 1.

[0044] This application also provides a zipper product, which can be footwear, clothing, bags, or other products including the aforementioned anti-snagging edge zipper.

[0045] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0046] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
