Description

Technical Field

[0001] This utility model relates to the technical field of trouser zippers, and more specifically, to a zipper assembly and trousers. Background Technology

[0002] With the rise of outdoor sports, outdoor clothing is increasingly focusing on functionality, such as waterproofing, rain and snow protection, temperature resistance, breathability, and ease of putting on and taking off. Outdoor pants are also increasingly being designed with zipper components to achieve functions such as waterproofing, breathability, and quick opening. Currently, there are pants on the market with multi-zipper pulls on the sides.

[0003] In existing technology, multi-pull zippers use vertical stitching on the zipper teeth at both ends of the knee area to prevent the zipper pull from sliding down, and the other end of the knee area also uses vertical stitching to prevent the zipper pull from continuing to pull upwards. However, relying on stitching to prevent the zipper pull from sliding down has the following problems: stitching is relatively troublesome and not aesthetically pleasing; after being pulled for a long time, the stitching is prone to loosening, and the zipper pull is prone to getting stuck in the stitching and not being able to be pulled up. In addition, the teeth between the two ends of the stitching can easily open, making it difficult to pull back.

[0004] In conclusion, how to reduce the difficulty of sewing and improve the convenience of zippers is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a zipper assembly and trousers, which effectively reduces the difficulty of sewing by setting stops at both ends of the knee area and avoids the risk of loosening caused by traditional sewing methods.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A zipper assembly includes a first fabric strip and a second fabric strip disposed opposite to each other, with interlocking teeth sewn between the first fabric strip and the second fabric strip, the first fabric strip and the second fabric strip being separated along their length into a pocket area, a knee area and a leg opening area, the knee area being located between the pocket area and the leg opening area;

[0008] A first stop and a second stop are respectively provided at both ends of the knee area;

[0009] The pocket area is provided with a plurality of first pull tabs to open or engage the teeth in the pocket area, and a third stop is provided at the end of the pocket area away from the knee area;

[0010] The trouser leg area is provided with several second pull heads to open or engage the teeth in the trouser leg area.

[0011] Preferably, there are two first zipper heads, which are arranged facing each other.

[0012] Preferably, there are two first zipper heads, which are arranged facing away from each other.

[0013] Preferably, there is one second pull tab, which opens in the direction close to the knee area.

[0014] Preferably, the first stop and the second stop are molten tooth stops.

[0015] Preferably, both the first and second fabric strips located in the knee area are toothless.

[0016] Preferably, both ends of the first and second fabric strips along their length are flat-cut to form flat-cut ends.

[0017] Preferably, the length of the flat-cut end is 2-5 mm.

[0018] A pair of trousers, wherein both sides of the trousers are sewn with a zipper assembly as described in any of the preceding claims.

[0019] Preferably, the trousers are provided with Velcro straps at the cuffs to prevent the second zipper pull from wobbling.

[0020] The zipper assembly and trousers provided in this application isolate the knee area from the pocket area and the leg opening area by setting a first stop and a second stop at both ends of the knee area. This effectively prevents the first zipper pull from sliding down and the second zipper pull from pulling up. Compared with the stitching blocking method in the prior art, this effectively reduces the sewing difficulty and improves the appearance of the trousers while providing better blocking effect for the first and second zipper pulls. Furthermore, by realizing the function of different areas in the entire zipper assembly, the sewing difficulty is further reduced and the sewing efficiency of garment manufacturers is improved.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar words used in this utility model do not indicate any order, quantity, or importance. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. Terms such as "up," "down," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly. This application discloses a zipper assembly and trousers.

[0030] The core of this utility model is to provide a zipper assembly and trousers.

[0031] First, it should be noted that the reference... Figure 2 and Figure 3 In existing technologies, the three-head zipper is commonly used. Figure 2 (as shown) and segmented zippers (i.e., two zippers, such as...) Figure 3 (As shown).

[0032] In adopting such Figure 2 When using a three-pull zipper as shown, the following problems may arise: the stitching is more complicated (i.e., Figure 2The center seam blocking area (7) is not aesthetically pleasing; over time, the seam can easily loosen, and the zipper pull can easily get stuck in the seam and cannot be pulled. In addition, the teeth between the two seam blocking areas can easily open, making it difficult to close them back; regular zippers have top and bottom pulls at both ends, about 2 cm long. When sewing the zipper at both ends, the pulls need to be folded and sewn, which can make the waistband and hem of the pants thicker and increase the difficulty of sewing.

[0033] And in adopting such Figure 3 When using a segmented zipper as shown, there are issues such as slower sewing efficiency for two zippers, more complicated trouser cutting, and an overall less aesthetically pleasing appearance for the trousers.

[0034] Based on this, the present invention provides a zipper assembly and trousers, which effectively solves the above-mentioned problems.

[0035] Please refer to Figure 1 The zipper assembly provided by this utility model includes a first fabric strip 1 and a second fabric strip 2 arranged opposite to each other. Interlocking teeth are sewn between the first fabric strip 1 and the second fabric strip 2. The first fabric strip 1 and the second fabric strip 2 are divided along their length into a pocket area 11, a knee area 12, and a leg opening area 13. The knee area 12 is located between the pocket area 11 and the leg opening area 13. A first stop 41 and a second stop 42 are respectively provided at both ends of the knee area 12. A plurality of first zipper pulls 31 are provided in the pocket area 11 to open or engage the teeth within the pocket area 11. A third stop 43 is provided at the end of the pocket area 11 away from the knee area 12. A plurality of second zipper pulls 32 are provided in the leg opening area 13 to open or engage the teeth within the leg opening area 13.

[0036] Compared with existing technologies ( Figure 2 In contrast, the zipper assembly in this application uses stoppers (i.e., first stopper 41 and second stopper 42) at the knee area 12 to block the first zipper pull 31 and the second zipper pull 32, thereby preventing the first zipper pull 31 from sliding down excessively or the second zipper pull from pulling up excessively. During the sewing process of the zipper assembly, since the first stopper 41 and the second stopper 42 are directly sewn onto the first fabric strip 1 and the second fabric strip 2, the first fabric strip 1 and the second fabric strip 2 can be directly sewn onto the desired pants, effectively reducing the sewing difficulty. Furthermore, compared to the stitching method used in the prior art, the first stopper 41 and the second stopper 42 can improve the aesthetics of the pants while providing a better blocking effect for the first zipper pull 31 and the second zipper pull 32.

[0037] The zipper assembly described above is described in detail below. The first fabric strip 1 and the second fabric strip 2 are respectively located at the waistband and hem of the pants, that is, the first fabric strip 1 and the second fabric strip 2 are set along the length of the pants, effectively ensuring the overall aesthetics of the pants. Depending on the area of ​​the pants, the first fabric strip 1 and the second fabric strip 2 can be divided into a pocket area (upper area) 11, a knee area (middle area) 12, and a hem area (lower area) 13.

[0038] A pocket for holding items can be provided in the pocket area 11. The pocket is opened and closed by a first zipper pull 31 located on the first fabric strap 1 and the second fabric strap 2 in the pocket area 11. Multiple first zipper pulls 31 can be provided. In this embodiment, two first zipper pulls 31 are used as an example (e.g., Figure 1 (As shown). The two first pull tabs 31 are used to open and close the first fabric strip 1 and the second fabric strip 2 in the pocket area 11. The first pull tab 31 near the waistband of the pants is blocked by the third stop 43, and the first pull tab near the knee area 12 is blocked by the first stop 41.

[0039] A zipper section can be installed at the trouser leg area 13, allowing the trouser leg to be opened by pulling upwards from the bottom, enabling quick trouser removal and re-wearing. Furthermore, due to the large opening of the trouser leg, shoes can be put on directly. The opening and closing of the trouser leg is achieved by a second pull head 32 located on the first fabric strip 1 and the second fabric strip 2 at the trouser leg area 13. Multiple second pull heads 32 can be provided; this embodiment uses one second pull head 32 as an example (e.g., ...). Figure 1 As shown), the second pull tab 32 opens in the direction close to the knee area 12. The second pull tab 32 is blocked at both ends of the leg opening 13 by a second stop 42 located at the end of the knee area 12 and a fourth stop 44 located at the end of the leg opening 13, respectively. Of course, to achieve further loosening of the leg opening 13, the fourth stop 44 located at the end of the leg opening 13 can be removed.

[0040] The aforementioned zipper assembly isolates the knee area 12 from the pocket area 11 and the leg opening area 13 by setting a first stop 41 and a second stop 42 at both ends of the knee area 12. This effectively prevents the first zipper pull 31 from sliding down and the second zipper pull 32 from pulling up. Compared with the stitching blocking method in the prior art, this effectively reduces the sewing difficulty and improves the appearance of the pants while providing a better blocking effect for the first zipper pull 31 and the second zipper pull 32.

[0041] The zipper assembly and trousers provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0042] In one specific implementation, reference is made to... Figure 1 a. Two first zipper pulls 31 are positioned opposite each other. Pulling down the upper first zipper pull 31 closes the teeth of the pocket area 11, and similarly, pulling up the lower first zipper pull 31 closes the teeth of the pocket area 11. However, it should be noted that when the pocket needs to be closed, the two first zipper pulls 31 must always be in a head-to-head closed state and can remain at any position between the first stop 41 and the third stop 43. At the same time, when the pocket needs to be opened, the distance between the two first zipper pulls 31 can be adjusted according to the required size of the pocket opening, thereby forming pocket openings of different sizes.

[0043] In one specific implementation, reference is made to... Figure 1 b. The two first zipper pulls 31 are positioned opposite each other. Pulling the upper first zipper pull 31 upwards and the lower first zipper pull 31 downwards closes the teeth of the pocket area 11, at which point the two first zipper pulls 31 respectively engage with the first stop 41 and the third stop 43. When it is necessary to open the pocket, the upper first zipper pull 31 can be pulled down to the first stop 41 and engage with the lower first zipper pull 31 to fully open the pocket, or the lower first zipper pull 31 can be pulled up to the third stop 43 and engage with the upper first zipper pull 31 to fully open the pocket. The positions of the two first zipper pulls 31 can also be adjusted as needed to partially or fully open the pocket.

[0044] It should be noted that both the first stop 41 and the second stop 42 mentioned above can be molten tooth stops (formed by melting plastic or nylon teeth at high temperatures). The molten plastic or nylon material will bond tightly to the target surface, forming a physical interlocking structure, providing a more stable fixing effect than glue or screws. At the same time, the molten material can fill tiny gaps, forming a completely sealed layer after solidification, effectively preventing the penetration of liquids, gases, or dust. Furthermore, since the entire zipper is used, the teeth (plastic material) can be melted and formed into stops, improving the utilization rate of the zipper assembly and reducing costs.

[0045] Optionally, the third stop 43 and the fourth stop 44 can also be melting tooth stops.

[0046] Based on any of the above embodiments, refer to Figure 1The first fabric strip 1 and the second fabric strip 2 located within the knee area 12 are both without teeth. Since the knee area 12 covers the knees when the trousers are worn, ensuring that the zippers in the pocket area 11 and the leg opening area 13 can be sewn together effectively reduces sewing steps while avoiding the complexity of the entire zipper assembly. This not only reduces material costs but also improves the flexibility of this area, allowing the trousers to better conform to the body's movement needs at the knee joint, enhancing wearing comfort. At the same time, this design avoids the problem of tooth damage caused by frequent bending, extending the lifespan of the zipper assembly.

[0047] Based on any of the above embodiments, refer to Figure 1 Both ends of the first fabric strip 1 and the second fabric strip 2 along their length are flat-cut to form flat-cut ends 5. In the prior art (such as...) Figure 2 (As shown) The zipper has top and bottom tabs at both ends, about 2 cm long. When sewing the zipper at both ends, the tabs need to be folded and sewn, which can easily make the waistband and hem thicker and increase the sewing difficulty. In this application, the top and bottom tabs of the first fabric tape 1 and the second fabric tape 2 (the parts of the zipper that extend in the opposite direction to the teeth) are flat-cut to form flat-cut ends 5. The length of the flat-cut ends 5 is 2-5 mm, so that the tabs do not need to be folded and sewn when sewing the zipper, and can be sewn directly, saving sewing time. At the same time, the thickness of the hem and waistband is not increased, and the appearance is better.

[0048] Please refer to Figure 1 and Figure 4 In addition to the aforementioned zipper assembly, this utility model also provides a pair of trousers with the zipper assembly sewn onto both sides. A Velcro fastener 6 is located at the hem of the trousers. When the second zipper pull 32 is pulled straight at the hem, the Velcro fastener 6 secures the second zipper pull 32, ensuring it does not wobble. Simultaneously, when the second zipper pull 32 is pulled upwards, the cylindrical hem of the trousers will open, which would be inconvenient for outdoor activities. The Velcro fastener 6 keeps the hem tight, while still maintaining the seam at the hem, effectively reducing the user's leg temperature. The structure of the remaining parts of the trousers is described in the prior art and will not be repeated here.

[0049] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0050] The zipper assembly and trousers provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
