Description

Technical Field

[0001] This application belongs to the technical field of zippers, clothing, etc., and specifically relates to an upper stop and an article with chain teeth. Background Technology

[0002] In related technologies, the upper stop component is generally fixed to the upper end of the zipper tooth using injection molding to limit the slider and prevent it from detaching from the zipper tooth. However, the upper stop component installed in this way cannot be disassembled, making it impossible to replace the slider when it is damaged, causing inconvenience to users. Summary of the Invention

[0003] The purpose of this application is to provide an upper stop and an article with chain teeth, which can solve the problem that the upper stop is fixed by injection molding, resulting in the inability to replace the zipper pull.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows: This application provides an upper stop member, including: a plug-in portion and a hook portion; The hook portion includes a connecting section, a snap-fit ​​section, and a bending section. The connecting section is located at one end of the insertion portion, the snap-fit ​​section is located on the side of the insertion portion, and the bending section is located between the connecting section and the snap-fit ​​section. A snap-fit ​​space is formed between the side wall of the snap-fit ​​section facing the plug and the side wall of the plug.

[0005] This application embodiment also provides an article with chain teeth, the article including fabric, nylon chain teeth and the above-mentioned upper stop, the nylon chain teeth being sewn into the edge area of ​​the fabric; The insertion part is inserted into the end of the nylon chain tooth; The nylon filaments of the nylon chain teeth are located in the snap-fit ​​space.

[0006] In this embodiment, the insert portion can be inserted into the end of the nylon chain tooth, and the snap-fit ​​section can snap a portion of the nylon thread of the nylon chain tooth into the snap-fit ​​space. This ensures the stability of the installation between the upper stop and the nylon chain tooth, preventing the upper stop from moving relative to or even detaching from the nylon chain tooth. Compared to related technologies that use injection molding to fix the upper stop to the upper end of the chain tooth, this embodiment does not use injection molding but instead uses an insert-fit snap-fit ​​method to achieve a detachable connection between the upper stop and the nylon chain tooth. This facilitates the installation and removal of the upper stop, making it easier to replace damaged zipper pulls and providing convenience for users. Attached Figure Description

Detailed Implementation

[0009] 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, 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.

[0010] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0011] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0012] refer to Figures 1 to 12 This application discloses an upper stop member 01, which is installed at the end of a nylon chain tooth 03 to limit the sliding pull head 06 connected to the nylon chain tooth 03 and prevent the pull head 06 from disengaging from the nylon chain tooth 03. The disclosed upper stop member 01 includes an insertion part 10 and a hook part 20.

[0013] The insertion portion 10 is used to insert into the end of the nylon chain tooth 03 so that the insertion portion 10 can be limited by the nylon chain tooth 03, which helps to improve the stability of the connection between the upper stop 01 and the nylon chain tooth 03. Optionally, at least a portion of the insertion portion 10 can be inserted into the inner cavity of the end of the nylon chain tooth 03 so that the nylon chain tooth 03 can limit the insertion portion 10 in all directions around its circumference.

[0014] The hook portion 20 is provided at one end of the insertion portion 10. Through the cooperation between the hook portion 20 and the insertion portion 10, the nylon filament of the nylon chain tooth 03 can be limited, so as to further improve the stability of the connection between the upper stop 01 and the nylon chain tooth 03, and effectively alleviate the problem of the upper stop 01 detaching from the nylon chain tooth 03.

[0015] refer to Figure 1 , Figure 2 and Figure 6The hook portion 20 includes a connecting section 21, a snap-fit ​​section 22, and a bending section 23. The connecting section 21 is located at one end of the insertion portion 10, the snap-fit ​​section 22 is located on the side of the insertion portion 10, and the bending section 23 is located between the connecting section 21 and the snap-fit ​​section 22.

[0016] Optionally, the connecting section 21 and one end of the plug-in part 10 can be fixedly connected or integrally formed; the connecting section 21, the snap-fit ​​section 22 and the bending section 23 can be connected in sequence, such as fixedly connected or integrally formed.

[0017] For example, the hook portion 20 can be a U-shaped structure, with one end of the U-shaped structure connected to the plug portion 10.

[0018] There can be a certain gap between the snap-fit ​​segment 22 and the side wall of the insertion part 10, so that the snap-fit ​​segment 22 facing the side wall of the insertion part 10 and the side wall of the insertion part 10 form a snap-fit ​​space 01a. In this way, when the upper stop 01 is installed to the end of the nylon chain tooth 03, the insertion part 10 is inserted into the end of the nylon chain tooth 03, and the snap-fit ​​segment 22 is located on the side of the nylon chain tooth 03, so that part of the nylon thread of the nylon chain tooth 03 is located in the snap-fit ​​space 01a and is limited by the snap-fit ​​segment 22 and the side wall of the insertion part 10. This can improve the stability of the connection between the upper stop 01 and the nylon chain tooth 03 and effectively alleviate the problem of the upper stop 01 detaching from the nylon chain tooth 03.

[0019] Compared to the related technologies that use injection molding to fix the upper stop 01 to the upper end of the chain tooth, the embodiment of this application does not use injection molding to fix it. Instead, it uses a plug-in and snap-fit ​​method to achieve a detachable connection between the upper stop 01 and the nylon chain tooth 03. This makes it easy to assemble and disassemble the upper stop 01, and thus makes it easier to replace the damaged zipper head 06, bringing convenience to the user.

[0020] Continue to refer to Figure 1 , Figure 2 and Figure 6 In some embodiments, the snap-fit ​​section 22 may have a snap-fit ​​groove 221 on the side wall facing the insertion part 10. The space enclosed between the snap-fit ​​groove 221 and the side wall of the insertion part 10 is the snap-fit ​​space 01a. In this way, when the upper stop 01 is connected to the end of the nylon chain tooth 03, a part of the nylon thread of the nylon chain tooth 03 can be snapped into the snap-fit ​​groove 221. The groove wall of the snap-fit ​​groove 221 and the side wall of the insertion part 10 limit the nylon thread and prevent the nylon thread from falling out of the snap-fit ​​groove 221.

[0021] Optionally, the depth of the slot 221 can be greater than the cross-sectional dimension of the nylon filament. In this case, the entire nylon filament can be located within the slot 221. Alternatively, the depth of the slot 221 can be less than the radial dimension of the nylon filament in the nylon chain tooth 03. In this case, a portion of the nylon filament is located within the slot 221, while another portion is located between the end face where the slot opening is located and the side wall of the insertion part 10. Regardless of the method, the side wall of the insertion part 10 can block the nylon filament, thus limiting its movement and effectively preventing it from detaching from the slot 221.

[0022] In other embodiments, the sidewall of the insertion part 10 may also be provided with a groove, which is disposed opposite to the slot 221, so that the slot 221 and the groove together form a larger snap-fit ​​space 01a, so as to accommodate larger nylon filaments.

[0023] refer to Figures 1 to 3 and Figure 6 In some embodiments, the side wall of the insertion part 10 may be provided with a snap-fit ​​protrusion 11, which is used to snap into the nylon chain tooth 03. In this way, when the insertion part 10 is inserted into the end of the nylon chain tooth 03, it can be snapped into the nylon thread by the snap-fit ​​protrusion 11 to prevent the insertion part 10 from moving in the direction of disengaging from the nylon chain tooth 03. This can improve the stability of the connection between the upper stop 01 and the nylon chain tooth 03 and effectively alleviate the problem of the insertion part 10 disengaging from the nylon chain tooth 03.

[0024] Optionally, the snap-fit ​​protrusion 11 may have a barb-like structure on the side wall of the insertion part 10. This structure facilitates the insertion part 10 into the end of the nylon chain tooth 03 and makes the insertion part 10 less prone to disengagement, thereby further improving the reliability and stability of the connection. In addition, the snap-fit ​​protrusion 11 may also have other shapes, such as columnar, block-shaped, wedge-shaped, ring-shaped, etc. The embodiments of this application do not specifically limit the shape of the snap-fit ​​protrusion 11.

[0025] In addition, the number of snap-fit ​​protrusions 11 can be one or more. When there are multiple snap-fit ​​protrusions 11, they can be arranged at intervals along the extension direction of the insertion part 10 so that multiple snap-fit ​​protrusions 11 can be snapped into the nylon thread respectively, thereby further improving the reliability and stability of the connection between the insertion part 10 and the nylon chain tooth 03.

[0026] refer to Figures 1 to 4In some embodiments, the snap-fit ​​protrusion 11 may protrude along a first direction, wherein the first direction, the extension direction of the insertion portion 10, and the direction of the snap-fit ​​segment 22 toward the sidewall of the insertion portion 10 are perpendicular to each other. Based on this arrangement, the snap-fit ​​segment 22 and the insertion portion 10 can cooperate to snap and limit the nylon thread in the direction of the snap-fit ​​segment 22 toward the sidewall of the insertion portion 10, and the snap-fit ​​protrusion 11 can snap and limit the nylon thread in the first direction, thereby achieving multiple limiting engagements between the upper stop 01 and the nylon thread, further improving the reliability and stability of the connection between the upper stop 01 and the nylon chain tooth 03.

[0027] In other embodiments, the first direction and the direction of the snap-fit ​​segment 22 toward the side wall of the plug-in portion 10 can also be at other angles other than 90°, such as 80°, 60°, etc., which can be set according to actual needs.

[0028] refer to Figure 3 In some embodiments, the insertion portion 10 may be provided with locking protrusions 11 on both sides opposite to each other along the first direction, and the plurality of locking protrusions 11 on each side are arranged at intervals along the extending direction of the insertion portion 10. Based on this, the plurality of locking protrusions 11 can be engaged with the nylon thread respectively, thereby further improving the reliability and stability of the connection between the insertion portion 10 and the nylon chain tooth 03; and, since the locking protrusions 11 on both sides can be engaged with the nylon thread respectively, it is beneficial to improve the force balance on both sides of the upper stop member 01, thereby further improving the stability of the connection between the upper stop member 01 and the nylon chain tooth 03.

[0029] In some embodiments, the hook portion 20 can be an elastic element. The end face of the snap-fit ​​section 22 facing the side wall of the insertion portion 10 is opposite to the side wall of the insertion portion 10 and a first gap M is provided between them. In its natural state, the first gap M can prevent the nylon filament of the nylon chain tooth 03 from naturally detaching through the snap-fit ​​section 22 and the side wall of the insertion portion 10. When the hook portion 20 undergoes elastic deformation, the first gap M can increase to allow the nylon filament of the nylon chain tooth 03 to pass through.

[0030] Specifically, in its natural state, the first gap M can be smaller than the cross-sectional dimension of the nylon filament of the nylon chain tooth 03 in the direction of the snap-fit ​​section 22 toward the side wall of the insertion portion 10; when the hook portion 20 undergoes elastic deformation, the first gap M can be larger than the cross-sectional dimension of the nylon filament of the nylon chain tooth 03 in the direction of the snap-fit ​​section 22 toward the side wall of the insertion portion 10. Here, the aforementioned cross-sectional dimension can be understood as the radial dimension of the nylon filament in the nylon chain tooth 03, or the dimension of the nylon filament in the direction of the snap-fit ​​section 22 toward the side wall of the insertion portion 10.

[0031] Based on the above configuration, when the nylon thread is inserted into the snap-fit ​​space 01a, it is not easy for the nylon thread to detach from the snap-fit ​​space 01a, thereby making it difficult for the upper stop 01 to detach from the nylon chain tooth 03. When it is necessary to remove the upper stop 01 from the nylon chain tooth 03, a force needs to be applied to the upper stop 01 to cause the hook portion 20 to undergo elastic deformation, thereby increasing the distance between the snap-fit ​​section 22 and the side wall of the insertion portion 10, so that the nylon thread can slide out from between the snap-fit ​​section 22 and the side wall of the insertion portion 10.

[0032] It should be noted that when a force is applied to the upper stop 01, at least a portion of the hook portion 20 can undergo elastic deformation, causing the locking section 22 to move away from the side wall of the insertion portion 10. When the force is released, the hook portion 20 can return to its original position, allowing the upper stop 01 to be reused. Of course, when the force is released, the hook portion 20 may not return to its original position; when the upper stop 01 is installed, a force can be applied to the upper stop 01 again to cause the hook portion 20 to return to its original position.

[0033] refer to Figure 1 and Figure 2 In some embodiments, the end of the snap-fit ​​segment 22 located away from the curved segment 23 in the slot 221 may be provided with a limiting end 222 on the side facing the insertion portion 10. One end of the limiting end 222 protrudes into the slot 221, and the other end of the limiting end 222 protrudes from the end face of the snap-fit ​​segment 22 away from the curved segment 23.

[0034] Based on the above configuration, during the installation of the upper stop 01 onto the nylon chain tooth 03, the other end of the limiting end 222 can guide the nylon thread to enter the slot 221. Furthermore, when the insertion part 10 moves toward the direction of disengaging from the nylon chain tooth 03, the nylon thread can move between one end of the limiting end 222 and the slot 221. Thus, the nylon thread can be wrapped by the side wall of the limiting end 222 and the slot 221 away from the bending section 23, thereby effectively preventing the nylon thread from disengaging from the slot 221, and thus effectively preventing the upper stop 01 from disengaging from the nylon chain tooth 03.

[0035] Optionally, a recessed portion may be provided on the side wall of the limiting end 222 facing the slot 221. The recessed portion can increase the contact area between the inner wall of the limiting end 222 and the nylon thread. In addition, the recessed portion can also play a certain role in wrapping the nylon thread, thereby effectively preventing the nylon thread from slipping out of the slot 221.

[0036] In addition, the surface of the other end of the limiting end 222 facing the insertion part 10 can be a curved surface, so that the curved surface can play a better guiding role for the nylon filament.

[0037] Optionally, if the snap-fit ​​section 22 is provided with a limiting end 222, the first gap M can be formed between the side of the limiting end 222 and the side wall of the plug-in portion 10.

[0038] In some embodiments, the snap-fit ​​protrusion 11 near the curved section 23 is correspondingly provided with the limiting end 222. In this way, the limiting end 222 and the corresponding snap-fit ​​protrusion 11 can respectively limit the nylon thread, which helps to improve the reliability and stability of the connection between the upper stop 01 and the nylon chain tooth 03.

[0039] refer to Figures 6 to 8 In other embodiments, the snap-fit ​​protrusion 11 may also protrude toward the side wall of the snap-fit ​​section 22. In this way, the side wall of the slot 221 away from the curved section 23 and the snap-fit ​​protrusion 11 can work together with the nylon wire to snap and limit the nylon wire, so as to prevent the nylon wire from leaving the snap-fit ​​space 01a.

[0040] Furthermore, the hook portion 20 can be an elastic element. The side wall of the snap-fit ​​section 22 located at the end of the slot 221 away from the bent section 23 is opposite to the snap-fit ​​protrusion 11 and a second gap N is provided between them. In its natural state, the second gap N prevents the nylon thread of the nylon chain tooth 03 from naturally detaching through the snap-fit ​​section 22 and the snap-fit ​​protrusion 11. When the hook portion 20 undergoes elastic deformation, the second gap N can increase to allow the nylon thread of the nylon chain tooth 03 to pass through.

[0041] Specifically, in its natural state, the second gap N can be smaller than the cross-sectional dimension of the nylon filament of the nylon chain tooth 03 in the direction of the snap-fit ​​section 22 toward the side wall of the insertion portion 10; when the hook portion 20 undergoes elastic deformation, the second gap N can be larger than the cross-sectional dimension of the nylon filament of the nylon chain tooth 03 in the direction of the snap-fit ​​section 22 toward the side wall of the insertion portion 10. Here, the aforementioned cross-sectional dimension can be understood as the radial dimension of the nylon filament in the nylon chain tooth 03, or the dimension of the nylon filament in the direction of the snap-fit ​​section 22 toward the side wall of the insertion portion 10.

[0042] Based on the above configuration, when the nylon thread is inserted into the snap-fit ​​space 01a, it is not easy for the nylon thread to detach from the snap-fit ​​space 01a, thereby making it difficult for the upper stop 01 to detach from the nylon chain tooth 03. When it is necessary to remove the upper stop 01 from the nylon chain tooth 03, a force needs to be applied to the upper stop 01 to cause the hook portion 20 to undergo elastic deformation. This causes the side wall of the snap-fit ​​section 22 located at the end of the snap-fit ​​section 221 away from the bent section 23 to move away from the side wall of the insertion portion 10 or the snap-fit ​​protrusion 11, increasing the distance between them. This facilitates the nylon thread sliding out between the snap-fit ​​section 22 and the side wall of the insertion portion 10 or the snap-fit ​​protrusion 11.

[0043] It should be noted that when a force is applied to the upper stop 01, at least a portion of the hook portion 20 can undergo elastic deformation, causing the locking section 22 to move away from the side wall of the insertion portion 10. When the force is released, the hook portion 20 can return to its original position, allowing the upper stop 01 to be reused. Of course, when the force is released, the hook portion 20 may not return to its original position; when the upper stop 01 is installed, a force can be applied to the upper stop 01 again to cause the hook portion 20 to return to its original position.

[0044] In some embodiments, the sidewall of the insertion portion 10 facing the snap-fit ​​section 22 may be provided with a plurality of snap-fit ​​protrusions 11, which are spaced apart along the extending direction of the insertion portion 10. Based on this, the plurality of snap-fit ​​protrusions 11 can be respectively snapped into nylon threads, thereby further improving the reliability and stability of the connection between the insertion portion 10 and the nylon chain teeth 03.

[0045] Furthermore, the snap-fit ​​protrusion 11 near the curved section 23 is correspondingly provided with the side wall of the snap-fit ​​section 22 located at the end of the slot 221 away from the curved section 23. In this way, the snap-fit ​​section 22 and the corresponding snap-fit ​​protrusion 11 can respectively limit the nylon thread, which helps to improve the reliability and stability of the connection between the upper stop 01 and the nylon chain tooth 03.

[0046] refer to Figure 6 In some embodiments, the distance between the end of the slot 221 away from the curved section 23 and the sidewall of the insertion portion 10 is a first distance, and the distance between the end of the slot 221 near the curved section 23 and the sidewall of the insertion portion 10 is a second distance, and the first distance can be greater than the second distance. Based on this arrangement, a larger space can be formed between the end of the slot 221 away from the curved section 23 and the sidewall of the insertion portion 10, so as to provide a larger space for the locking protrusion 11 and effectively prevent interference between the end of the slot 221 away from the curved section 23 and the locking protrusion 11.

[0047] Additionally, there may be a gap between the end of the slot 221 away from the curved section 23 and the snap protrusion 11, so that the nylon thread can be squeezed into the snap space 01a through the gap.

[0048] In some embodiments, the insertion portion 10 and the hook portion 20 can be integrally formed, which is beneficial to improving the manufacturing efficiency and overall strength of the upper stop 01. Optionally, the upper stop 01 can be an integrally injection molded part.

[0049] In other embodiments, the hook portion 20 can also be fixedly connected to one end of the insertion portion 10 via the connecting section 21, such as by snap-fit, insertion, screwing, or bonding, as long as the connection is secure, the specific form is not limited.

[0050] Optionally, the hook portion 20 can be made of plastic, or of other materials, without specific limitations.

[0051] refer to Figure 1 , Figure 2 and Figure 6 In some embodiments, the end of the plug portion 10 away from the hook portion 20 may be provided with a pointed structure 12. The pointed structure 12 can facilitate the insertion of the plug portion 10 into the end of the nylon chain tooth 03.

[0052] Based on the aforementioned upper stop 01, this application embodiment also discloses an article with chain teeth, see reference. Figure 4 , Figure 5 , Figures 8 to 12 The disclosed items include fabric 02, nylon chain teeth 03, and the aforementioned upper stop 01. The nylon chain teeth 03 are sewn onto the edge area of ​​the fabric 02, the insertion part 10 is inserted into the end of the nylon chain teeth 03, and a portion of the nylon filaments of the nylon chain teeth 03 is located in the snap-fit ​​space 01a.

[0053] Based on the above configuration, the upper stop 01 and the nylon chain tooth 03 are stably connected by the insertion and engagement of the insertion part 10 and the nylon thread being clamped and limited in the clamping space 01a, and the upper stop 01 is easy to disassemble and assemble.

[0054] In some embodiments, the article may further include a core thread 04 that passes through the nylon chain teeth 03. Optionally, the nylon chain teeth 03 and the core thread 04 may be sewn together to the edge of the fabric 02 using stitching 05.

[0055] The portion of the plug 10 inserted into the nylon chain tooth 03 abuts against the core wire 04. In this way, the core wire 04 can play a certain limiting role on the plug 10, thereby improving the stability of the plug 10 within the nylon chain tooth 03.

[0056] In some embodiments, the insertion portion 10 is press-fitted with the nylon chain tooth 03, so that the nylon chain tooth 03 can limit the insertion portion 10 and prevent the insertion portion 10 from disengaging from the nylon chain tooth 03.

[0057] refer to Figure 3 and Figure 11In some more specific embodiments, when the plug-in portion 10 can be provided with snap-fit ​​protrusions 11 on both sides opposite to each other along the first direction, the maximum distance of the plug-in portion 10 in the first direction is A1. Correspondingly, the distance of the inner cavity of the nylon chain tooth 03 in the first direction is A2, and A1≥A2. In this way, the plug-in portion 10 can be accommodated by the inner cavity of the nylon chain tooth 03, and the snap-fit ​​protrusions 11 on both sides can form a snap-fit ​​with the nylon chain tooth 03 through interference fit, which can help improve the stability of the upper stop 01.

[0058] refer to Figure 6 and Figure 11 In some more specific embodiments, when the snap-fit ​​protrusion 11 can also protrude toward the side wall of the snap-fit ​​section 22, the maximum distance of the insertion part 10 along the protrusion direction at the snap-fit ​​protrusion 11 is A3. Correspondingly, the maximum distance between the inner wall of the nylon chain tooth 03 and the outer wall of the core wire 04 is A4, and A3≥A4. In this way, the inner cavity of the nylon chain tooth 03 can accommodate the insertion part 10, and the snap-fit ​​protrusion 11 and the insertion part 10, which are away from the side wall of the snap-fit ​​protrusion 11, respectively form a locking position with the inner wall of the nylon chain tooth 03 and the core wire 04 through interference fit, which can help improve the stability of the upper stop 01.

[0059] In some embodiments, the article with teeth can be a zipper or clothing; in addition, the article with teeth can also be a flexible bag. Of course, other components are also possible, and no specific limitations are made here.
