Description

Technical Field

[0001] This application relates to the field of zipper technology, and in particular to a zipper pull and a zipper tip. Background Technology

[0002] With the rise of outdoor sportswear in the global fashion industry, many clothing accessories on the market incorporate sports elements, and a notable manifestation of this is the increasing number of pull tabs connecting the zipper cords.

[0003] However, the pull tabs of pull heads that can be fitted with pull cords on the market are currently designed in a relatively basic way, with simple assembly methods. The connection between the pull cord and the pull tab is difficult to present a variety of matching effects. Furthermore, after the pull cord and pull tab are combined, problems such as the cord becoming loose, falling off, or becoming crooked are prone to occur, which affects the consumer's user experience.

[0004] Therefore, in view of the above problems, how to improve the diversified assembly and assembly stability of pull ropes and pull tabs 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 a pull tab and pull head that enable diverse assembly of the pull cord and pull tab, improve the fixing effect of the pull cord on the pull tab, and meet consumers' increasingly demanding quality requirements for functionality and design.

[0006] To achieve the above objectives, this application provides a pull tab, wherein the pull tab is provided with a first through hole and a second through hole extending along its thickness direction;

[0007] The first perforation and the second perforation are distributed along the length direction of the pull tab, and the pull tab between the first perforation and the second perforation forms a middle crossbeam;

[0008] The end of the first perforation near the second perforation has a receiving space to accommodate the pull rope;

[0009] The second perforation has a wide end near the first perforation and a narrow end away from the first perforation;

[0010] In the width direction of the pull tab, the two opposite sidewalls of the receiving space are in contact with the pull cord, and / or, the second perforation is in contact with the two opposite sidewalls of the narrow end of the pull cord;

[0011] The pull tab has a hollow structure extending along the length direction at one end near the narrow end. The hollow structure is connected to the narrow end, and the hollow structure and the upper and / or lower surface of the pull tab form a crossbeam for threading the pull rope.

[0012] Optionally, the end of the accommodating space near the second perforation is constructed as an arc-shaped inner wall that gradually narrows along the length direction from the first perforation to the second perforation.

[0013] Optionally, the two opposite sidewalls of the wide end in the width direction contact the lateral fold of the pull rope.

[0014] Optionally, the hollow structure includes a third through hole, which forms an upper crossbeam with the upper surface of the pull tab, and the third through hole forms a lower crossbeam with the lower surface of the pull tab.

[0015] Optionally, the third perforation structure is an elliptical hole with its major axis aligned with the length direction and its minor axis aligned with the thickness direction.

[0016] Optionally, the hollow structure includes a slot on the lower surface of the pull tab, and an upper crossbeam is formed between the slot and the upper surface of the pull tab.

[0017] Optionally, the thickness of the pull tab gradually increases along the length direction from the first perforation to the second perforation.

[0018] Optionally, the two opposite sidewalls of the wide end in the width direction have an arc that matches the outer contour of the pull rope.

[0019] Optionally, a transition arc is provided at the connection between the sidewall of the wide end and the sidewall of the narrow end, and the end of the pull tab near the narrow end is constructed as a gradually narrowing arc outer contour.

[0020] A zipper puller includes a pull body and a pull tab as described in any of the preceding claims.

[0021] The beneficial effects of this application are that the pull tab is movably connected to the pull body through the first perforation, and a receiving space for accommodating the pull rope is formed at the end of the first perforation near the second perforation. The pull tab between the first and second perforations forms a central crossbeam. The pull rope can pass through the hollow structure and be tied to the central crossbeam, forming a first rope-threading method. In this rope-threading method, the pull rope can contact the two opposite side walls of the receiving space, thereby restricting the lateral movement of the pull rope and giving the pull rope a better fixing effect. The hollow structure and the upper and / or lower surface of the pull tab form a crossbeam part for threading the pull rope. Therefore, the pull rope can be directly threaded onto the crossbeam part, forming a second or third rope-threading method. In the second and third rope-threading methods, the pull rope contacts the two opposite side walls of the narrow end of the second perforation, which can also restrict the lateral movement of the pull rope and give the pull rope a better fixing effect. As can be seen, the pull tab of this application can provide a variety of ways to thread the pull cord, meet the different threading needs of consumers, and each threading method can limit the lateral position of the pull cord, ensuring that the pull cord will not sway left and right, thus meeting the increasingly high quality requirements of consumers for functionality and design.

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. 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.

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.

[0041] 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.

[0042] like Figure 1 and Figure 2 As shown, in this embodiment, a pull tab is provided. The pull tab 1 has a first through hole 11 and a second through hole 12 that extend through its thickness direction. The first through hole 11 and the second through hole 12 are distributed along the length direction of the pull tab 1, and a middle crossbeam 14 is formed on the pull tab 1 between the first through hole 11 and the second through hole 12. The pull tab 1 is movably connected to the pull body through the first through hole 11. The length of the first through hole 11 is slightly longer than that of the conventional one, so that the first through hole 11 has a certain amount of remaining space in addition to connecting the pull body. That is, after the first through hole 11 is connected to the pull body, the end of the first through hole 11 near the second through hole 12 has a receiving space 111 for accommodating the pull rope 2.

[0043] The second perforation 12 has a wide end 121 close to the first perforation 11 and a narrow end 122 away from the first perforation 11. Please refer to... Figure 2 In addition to reducing the weight of the pull tab 1 and making it more agile, the second perforation 12 can also be used to store the knot, making the pull rope 2 and the pull tab 1 more integrated and flat. Specifically, the shape of the second perforation 12 is similar to a cloud-shaped outline that is wider at the top and narrower at the bottom. The wider end 121 at the top can better pass the rope through during the assembly process, and has enough space to accommodate the lateral fold-back part 21 (knot) of the pull rope 2, so that the knot is hidden inside the pull tab 1.

[0044] In addition, when the pull rope 2 is threaded onto the middle crossbeam 14, the two opposite sidewalls of the accommodating space 111 in the width direction of the pull piece 1 come into contact with the pull rope 2, thereby restricting the lateral movement of the pull rope 2 by the accommodating space 111 and ensuring the stability of the threading of the pull rope 2.

[0045] A hollow structure 13 extending along the length direction is provided at one end of the pull tab 1 near the narrow end 122. Please refer to [reference needed]. Figure 1 and Figure 2 The hollow structure 13 is connected to the narrow end 122 of the second through hole 12, so that the rope can pass through the hollow structure 13 to reach the second through hole 12. The hollow structure 13 can form a crossbeam part for binding the pull rope 2 with the upper and / or lower surface of the pull piece 1.

[0046] Through the above-described configuration, the pull tab 1 of this application can provide at least three ways to thread the pull rope 2. The first way is that the pull rope 2 enters the second through hole 12 through the hollow structure 13 and is tied to the middle crossbeam 14, and the pull rope 2 can be restricted from lateral movement by the accommodating space 111. The second way is that the pull rope 2 enters the second through hole 12 through the hollow structure 13 and is tied to the crossbeam formed by the hollow structure 13 and the upper surface of the pull tab 1, and the pull rope 2 is restricted from lateral movement by the narrow end 122. The third way is that the pull rope 2 enters the second through hole 12 through the hollow structure 13 and is tied to the crossbeam formed by the hollow structure 13 and the lower surface of the pull tab 1, and the pull rope 2 is restricted from lateral movement by the narrow end 122.

[0047] It should be noted that in the second and third rope threading methods described above, the narrow end 122 of the second perforation 12 can accommodate the two rows of ropes after they are joined together, so that the narrow end 122 forms a groove structure that restricts the lateral movement of the rope.

[0048] In summary, the pull tab 1 of this application can provide a variety of ways to thread the pull cord 2, meeting the different threading needs of consumers. Moreover, each threading method can limit the lateral position of the pull cord 2, ensuring that the pull cord 2 will not sway left and right, thus meeting the increasingly high quality requirements of consumers for functionality and design.

[0049] The end of the accommodating space 111 near the second perforation 12 is constructed as follows: the inner wall of the arc gradually narrows along the length from the first perforation 11 to the second perforation 12, which can better gather the pull rope 2; at the same time, when the pull rope 2 is tied to the middle crossbeam 14, please refer to... Figure 5 and Figure 6The lateral fold 21 of the pull rope 2 can be stored in the wide end 121 of the second perforation 12. The two opposite sidewalls of the wide end 121 in the width direction contact the lateral fold 21 of the pull rope 2, and the two opposite sidewalls of the wide end 121 in the width direction have an arc that matches the outer contour of the pull rope 2, which can reduce the wear of the lateral fold 21. The lateral fold 21 perfectly fits the contour of the wide end 121, making the pull tab 1 appear flatter and more integrated. The assembly method is also the most secure, and the rope is not easy to fall off.

[0050] In some embodiments, the perforated structure 13 can be a third through hole 131, please refer to Figure 3 The third perforation 131 forms an upper crossbeam 15 with the upper surface of the pull tab 1, and the third perforation 131 forms a lower crossbeam 16 with the lower surface of the pull tab 1; when the pull rope 2 is threaded onto the upper crossbeam 15, please refer to... Figure 7 and Figure 8 The lateral fold 21 of the pull rope 2 is close to the front of the pull rope 2, making the rope protrude; when the pull rope 2 is threaded through the lower crossbeam 16, please refer to... Figure 9 and Figure 10 The horizontal fold 21 of the pull cord 2 is close to the back of the pull cord 2, which weakens the cord and highlights the pull piece 1 itself; through the above method, consumers can choose different binding methods according to their own preferences, thereby showing different visual effects.

[0051] Furthermore, the third perforation 131 can be a regular hole such as a square hole or a round hole, or it can be other irregular holes, without much restriction here; considering that the pull rope 2 needs to pass through the third perforation 131 in a closed manner, this application uses an elliptical hole as the third perforation 131. The major axis of the elliptical hole is in the same direction as the length direction of the pull piece 1, and the minor axis is in the same direction as the thickness direction of the pull piece 1, which can better utilize the pull rope 2 in a closed manner and is more conducive to demolding during the manufacturing process.

[0052] In some embodiments, the hollow structure 13 can also be a slot 132 provided on the lower surface of the pull tab 1. Please refer to Figure 4 The slot 132 forms an upper crossbeam 15 with the upper surface of the pull tab 1. Since the slot 132 is open on the side facing the lower surface of the pull tab 1, it cannot form a lower crossbeam 16 with the lower surface of the pull tab 1. Therefore, the way the pull rope 2 is threaded can only be the first or the second way. However, compared with the hollow structure 13 having a third perforation 131, the advantage of the slot 132 is that the pull rope 2 is easier to thread into the second perforation 12, which is convenient for binding with the middle crossbeam 14 or the upper crossbeam 15. This is suitable for situations where the end of the pull rope 2 has a hanging part, a knot, or is dipped in glue.

[0053] In order to provide sufficient space for the hollow structure 13 to thread the cord, the thickness of the pull tab 1 can be gradually increased along the length of the first perforation 11 to the second perforation 12. At the same time, the increase in the thickness of the tail of the pull tab 1 can also enhance the grip of the pull tab 1 and provide consumers with a good user experience.

[0054] In some embodiments, a transition arc is provided at the connection between the sidewall of the wide end 121 and the sidewall of the narrow end 122, which can effectively gather the rope in the narrow end 122 and ensure the rope's tucked-in effect, preventing the rope from moving left and right or becoming loose. In addition, the design of the narrow end 122 is beneficial for constructing a gradually narrowing arc outer contour at the end of the pull tab 1 near the narrow end 122, making the overall proportion of the pull tab 1 more aesthetically pleasing.

[0055] This application also provides a zipper head, which includes a zipper body and the aforementioned zipper tab 1, wherein the zipper tab 1 is connected to the zipper body through a first through hole 11.

[0056] 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.

[0057] 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.
