[0002] This application claims priority to two Chinese patent applications filed on March 24, 2025, entitled "Zipper Stop and Zipper Assembly" (application number 202510353973.1) and "Zipper Stop and Zipper Assembly" (application number 202520526327.6), the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the technical field of clothing, specifically relating to a zipper stop and a zipper assembly. Background Technology

[0004] In the production process of zippers in related technologies, a stop is installed after the zipper teeth or the zipper pull is installed. By setting the stop, the range of motion of the zipper pull can be limited, and the zipper pull can also be prevented from coming off the zipper teeth.

[0005] Taking the upper stop in a common open-type resin zipper as an example, the upper stop is injection molded onto the fabric belt along with the resin zipper teeth. When the zipper pull moves to the top of the zipper teeth, it is blocked by the upper stop, preventing the zipper pull from detaching from the zipper teeth. However, this type of stop can only be installed in a fixed position on the zipper teeth (usually at the end of the zipper teeth), and its position cannot be adjusted or disassembled as needed. As a result, the zipper pull can only move within a fixed range and cannot be easily disassembled, thus failing to meet people's usage needs. Summary of the Invention

[0006] This application provides a zipper stop, comprising: a stop body; the stop body having a receiving cavity for accommodating zipper teeth, the receiving cavity extending through the stop body at least along a first direction; the stop body having a first clamping opening on one side along a second direction that is expandable or contractible along the first direction and allows the zipper teeth to pass through, the first clamping opening communicating with the receiving cavity and extending through both sides of the receiving cavity wall along a third direction; the first direction, the second direction, and the third direction are perpendicular to each other.

[0007] This application embodiment also provides a zipper assembly, including: a pair of fabric tapes, zipper teeth, a zipper pull, and the aforementioned zipper stop; the zipper teeth are connected to the inner edges of the pair of fabric tapes, the zipper pull is slidably connected to the zipper teeth, and when the zipper pull slides back and forth, the zipper teeth on each of the pair of fabric tapes can engage or disengage with each other; the zipper stop is detachably sleeved on the zipper teeth.

Detailed Implementation

[0021] 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.

[0022] 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.

[0023] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0024] Referring to Figures 1 to 12, this application discloses a zipper stop 01 for installation onto the zipper teeth 02 to block the zipper pull 04 and prevent the zipper pull 04 from disengaging from the zipper teeth 02. The disclosed zipper stop 01 includes a stop body 10.

[0025] The stop body 10 is provided with a receiving cavity M, which is used to receive the chain tooth 02, and the receiving cavity M penetrates the stop body 10 at least along a first direction. Based on this, the stop body 10 can be installed onto the chain tooth 02 to ensure the installation stability of the stop body 10. Of course, the receiving space can also provide receiving space for the chain tooth 02, which can avoid assembly interference and reduce the overall volume of the zipper stop 01.

[0026] To facilitate the installation and engagement of the stop body 10 and the zipper tooth 02, a first clamping opening N1 may be provided on one side of the stop body 10 along the second direction. This first clamping opening N1 can expand or contract along the first direction, allowing the zipper tooth 02 to pass through. The first clamping opening N1 communicates with the receiving cavity M, penetrating both sides of the receiving cavity M along the third direction. Therefore, when installing the stop body 10, the first clamping opening N1 can be inserted into the zipper tooth 02, causing it to expand along the first direction, allowing the zipper tooth 02 to enter the receiving cavity M through the first clamping opening N1. Once the zipper tooth 02 enters the receiving cavity M, the first clamping opening N1 contracts along the first direction and clamps the zipper tooth 02, thus ensuring the installation stability of the zipper stop 01.

[0027] Of course, when it is necessary to disassemble the zipper stop 01, a force can be applied to the stop body 10 to squeeze the chain teeth 02 by the inner wall of the receiving cavity M, so that the first clamp N1 expands in the first direction, thereby allowing the chain teeth 02 to disengage from the receiving cavity M through the first clamp N1, thus realizing the disassembly of the zipper stop 01.

[0028] In addition, when the zipper stop 01 is installed on the zipper tooth 02 located on the fabric tape 03, the first clamp N1 can also be engaged with the edge of the fabric tape 03 to provide clearance space for the edge of the fabric tape 03 and prevent assembly interference.

[0029] In this embodiment, the first direction, the second direction, and the third direction are perpendicular to each other. Optionally, the first direction can be the thickness direction of the zipper, the second direction can be the width direction of the zipper, and the third direction can be the length direction of the zipper.

[0030] Based on the above configuration, the zipper stop 01 in this embodiment can be installed onto the zipper tooth 02 through the expansion and contraction of the first clamp N1. This ensures the installation stability of the zipper stop 01 and prevents it from falling off, while also facilitating installation and disassembly. Furthermore, the zipper stop 01 can be installed onto zipper teeth 02 at different positions as needed, thereby changing the movement range of the zipper pull 04 and meeting different user requirements. Additionally, the stop body 10 in this embodiment has a relatively simple structure and sufficient strength to withstand impacts from the zipper pull 04, reducing costs while ensuring reliability.

[0031] To form the first clamping opening N1, the stop body 10 may include a first clamping portion 11, a second clamping portion 12, and a connecting portion 13, as shown in Figures 4, 7, and 11. The first clamping portion 11 and the second clamping portion 12 are spaced apart along a first direction, and the connecting portion 13 connects between the first clamping portion 11 and the second clamping portion 12, forming the first clamping opening N1 between them. Based on this, the stop body 10 can have an overall concave structure, with the first clamping opening N1 formed on one side along a second direction to facilitate the passage of the chain teeth 02. Optionally, the connecting portion 13 may connect to one end of the first clamping portion 11 and the second clamping portion 12 along the second direction, and be positioned opposite to the first clamping opening N1.

[0032] In some embodiments, the first clamping part 11, the second clamping part 12, and the connecting part 13 are an integral structure, that is, the entire stop body 10 is an integral structure, such as an injection-molded structure; in other embodiments, the first clamping part 11, the second clamping part 12, and the connecting part 13 can also be independent of each other, and the stop body 10 is formed by fixing the connecting part 13 to the first clamping part 11 and the second clamping part 12 respectively, such as by welding, bonding, snap-fitting, etc.

[0033] In addition, the receiving cavity M passes through the first clamping part 11 and the second clamping part 12 along the first direction, which can provide a larger space for accommodating the chain tooth 02, allowing a part of the chain tooth 02 to enter the through space of the first clamping part 11 and the through space of the second clamping part 12. On the one hand, this prevents the stop body 10 from interfering with the chain tooth 02 during assembly, and on the other hand, it can also help reduce the volume of the stop body 10.

[0034] Referring to Figures 2 to 4, in some embodiments, the connecting portion 13 can close the accommodating cavity M in the circumferential direction of the stop body 10, thereby increasing the contact area between the stop body 10 and the chain tooth 02, improving the installation stability of the stop body 10, and of course, also improving the overall strength of the stop body 10, so that the connecting portion 13 will not be damaged during the expansion or contraction of the first clamping portion 11 and the second clamping portion 12, ensuring that there is a sufficiently large clamping force between the first clamping portion 11 and the second clamping portion 12.

[0035] In some other embodiments, the connecting portion 13 may not close the receiving cavity M in the circumferential direction of the stop body 10. In this case, the end of the chain tooth 02 may be exposed relative to the stop body 10, which may also help to reduce the volume of the stop body 10.

[0036] Referring to Figures 5 to 11, the receiving cavity M can pass through the connecting portion 13 along the second direction to form a second clamping opening N2. This second clamping opening N2 communicates with the receiving cavity M and can expand or contract along the third direction. Based on this, when the zipper stop 01 is installed to the zipper tooth 02, the second clamping opening N2 can clamp both sides of the zipper tooth 02 along the third direction, thereby improving the installation stability of the zipper stop 01 and the zipper tooth 02. Furthermore, by allowing the end of the zipper tooth 02 to extend into the second clamping opening N2, the connecting portion 13 is prevented from blocking the zipper tooth 02, which helps to reduce the length of the zipper stop 01 in the second direction, reduce the volume of the zipper stop 01, and also save the materials required to manufacture the zipper stop 01.

[0037] It should be noted that the connecting part 13 is penetrated by the cavity M in the entire first direction to form the second clamp N2.

[0038] Referring to Figures 2 to 11, in some embodiments, the first clamping part 11 may include a first swing arm 111, a second swing arm 112, and a first cross arm 113. The first swing arm 111 and the second swing arm 112 both extend along a second direction and are spaced apart along a third direction. The first cross arm 113 extends along a third direction and is connected to one end of each of the first swing arm 111 and the second swing arm 112 along the second direction. Based on this, the first swing arm 111, the second swing arm 112, and the first cross arm 113 can form a concave space, which is used to accommodate a portion of the chain tooth 02. It should be noted that this concave space is the space formed by the cavity M penetrating through the first clamping part 11.

[0039] Similarly, the second clamping part 12 may include a third swing arm 121, a fourth swing arm 122, and a second horizontal arm 123. The third swing arm 121 and the fourth swing arm 122 both extend along a second direction and are spaced apart along a third direction. The second horizontal arm 123 extends along a third direction and connects to one end of each of the third swing arm 121 and the fourth swing arm 122 along the second direction. Based on this, the third swing arm 121, the fourth swing arm 122, and the second horizontal arm 123 can form another concave space, which is used to accommodate a portion of the chain tooth 02. It should be noted that this concave space is the space formed by the cavity M penetrating through the second clamping part 12.

[0040] Furthermore, the other end of each of the first swing arm 111, the second swing arm 112, the third swing arm 121, and the fourth swing arm 122 along the second direction is connected to the connecting part 13. Based on this, the connecting part 13 can bear the load of the first swing arm 111, the second swing arm 112, the third swing arm 121, and the fourth swing arm 122 to ensure the stability of each swing arm.

[0041] In addition, the first horizontal arm 113 and the second horizontal arm 123 together form the first clamping opening N1. Thus, when the chain tooth 02 enters the first clamping opening N1, the first horizontal arm 113 and the second horizontal arm 123 can be relatively far apart. After the chain tooth 02 passes through the first clamping opening N1, the first horizontal arm 113 and the second horizontal arm 123 are relatively close together.

[0042] Based on the above configuration, after the zipper tooth 02 is inserted into the receiving cavity M, the first swing arm 111, the second swing arm 112, and the first cross arm 113 can cooperate around one side of the zipper tooth 02 along the first direction, and the third swing arm 121, the fourth swing arm 122, and the second cross arm 123 can cooperate around the other side of the zipper tooth 02 along the first direction. This can improve the stability of the zipper stop 01 and the zipper tooth 02, and prevent the zipper tooth 02 stop from moving relative to the zipper tooth 02 or even falling off.

[0043] Referring to Figures 7 and 11, in some embodiments, the connecting portion 13 may include a first upright arm 131 and a second upright arm 132, both extending along a first direction and spaced apart along a third direction. The first upright arm 131 connects the first swing arm 111 and the third swing arm 121 at their respective ends along a second direction away from the first horizontal arm 113 and the second horizontal arm 123, thus connecting and supporting the first swing arm 111 and the third swing arm 121 to ensure their stability. The second upright arm 132 connects the second swing arm 112 and the fourth swing arm 122 at their respective ends along a second direction away from the first horizontal arm 113 and the second horizontal arm 123, thus connecting and supporting the second swing arm 112 and the fourth swing arm 122 to ensure their stability.

[0044] In addition, the first upright arm 131 and the second upright arm 132 can together form the second clamping mouth N2. In this way, when the zipper tooth 02 enters the second clamping mouth N2, the first upright arm 131 and the second upright arm 132 can be relatively far apart, so that the two sides of the zipper tooth 02 can be clamped in the third direction by the first upright arm 131 and the second upright arm 132 to ensure the installation stability of the zipper stop 01.

[0045] Referring to Figures 9 to 12, in some embodiments, the zipper stop 01 may further include a reinforcing member 20, which is connected between the first upright arm 131 and the second upright arm 132. Therefore, the reinforcing member 20 can improve the strength of the first upright arm 131 and the second upright arm 132, thereby improving the overall strength and rigidity of the stop body 10 and effectively mitigating the occurrence of arbitrary deformation of the stop body 10.

[0046] Optionally, the reinforcing member 20 and the stop body 10 can be an integral structure, such as the reinforcing member 20 and the stop body 10 being an integral injection molded part; of course, in other embodiments, the reinforcing member 20 and the stop body 10 can also be separate structures, and the reinforcing member 20 can be installed onto the stop body 10.

[0047] In addition, when the zipper stop 01 is installed to the zipper tooth 02, the reinforcing member 20 can also cooperate with the zipper tooth 02 to further improve the installation stability of the zipper stop 01.

[0048] Optionally, the front end of the zipper tooth 02 may be provided with a groove 0221. When the zipper stop 01 is installed on the zipper tooth 02, the reinforcing member 20 can be embedded in the groove 0221. This can improve the reliability of the zipper stop 01 and the zipper tooth 02, and also prevent the reinforcing member 20 and the zipper tooth 02 from interfering with each other during assembly.

[0049] Referring to Figures 4, 7, and 11, in some embodiments, the side of the first cross arm 113 facing the second cross arm 123 may be provided with a first clearance step 1131. This first clearance step 1131 is used to cooperate with the step structure 0241 on the side of the tail 024 of the chain tooth 02. Thus, when the zipper stop 01 is installed to the chain tooth 02, the first clearance step 1131 can cooperate with the step structure 0241 on the side of the tail 024 of the chain tooth 02. This allows the chain tooth 02 to limit the first cross arm 113 in the second direction, preventing the zipper stop 01 from disengaging from the chain tooth 02. Furthermore, by providing the first clearance step 1131, the side of the tail 024 of the chain tooth 02 can be cleared, ensuring that the first cross arm 113 can cooperate well with the side of the tail 024 of the chain tooth 02.

[0050] Similarly, the side of the second cross arm 123 facing the first cross arm 113 may be provided with a second clearance step 1231. This second clearance step 1231 is used to cooperate with the step structure 0241 on the other side of the tail 024 of the chain tooth 02. In this way, when the zipper stop 01 is installed to the chain tooth 02, the second clearance step 1231 can cooperate with the step structure 0241 on the other side of the tail 024 of the chain tooth 02. This allows the chain tooth 02 to limit the second cross arm 123 in the second direction, preventing the zipper stop 01 from disengaging from the chain tooth 02. Furthermore, by providing the second clearance step 1231, the other side of the tail 024 of the chain tooth 02 can be cleared, ensuring that the second cross arm 123 can cooperate well with the other side of the tail 024 of the chain tooth 02.

[0051] Referring to Figures 4, 7, and 11, in some embodiments, the receiving cavity M may have a first inner cavity wall and a second inner cavity wall arranged opposite to each other along a third direction. Specifically, the first inner cavity wall may have a first protrusion 133 protruding into the receiving cavity M in the area where the connecting portion 13 is located, and the second inner cavity wall may have a second protrusion 134 protruding into the receiving cavity M in the area where the connecting portion 13 is located. The first protrusion 133 and the second protrusion 134 are arranged opposite to each other along a third direction, forming a narrow slit for accommodating the recess 0231 of the zipper tooth 02. Based on this arrangement, the mating area can be increased by the cooperation of the first protrusion 133 and the second protrusion 134 with the recess 0231 of the zipper tooth 02, thereby improving the installation stability of the zipper stop 01. Furthermore, it can reduce the difficulty for users to install and remove the zipper stop 01, allowing for easy installation or removal of the zipper stop 01.

[0052] Optionally, the first protrusion 133 can be located in the area where the first upright arm 131 is located, and the second protrusion 134 can be located in the area where the second upright arm 132 is located, so that when the second clamp N2 formed by the first upright arm 131 and the second upright arm 132 clamps the chain tooth 02, the first upright arm 131 and the second upright arm 132 can be effectively prevented from disengaging from the chain tooth 02, thereby improving the installation stability of the zipper stop 01.

[0053] Referring to Figures 4, 7, and 11, in some embodiments, the first protrusion 133 may have a first clearance groove 1331 on the sidewall facing the first clamping opening N1. This first clearance groove 1331 is located between the first clamping portion 11 and the second clamping portion 12, and extends through the first protrusion 133 in a third direction. This arrangement increases the space within the first clamping opening N1, providing ample space for accommodating other components. Optionally, when the zipper stop 01 is installed to the zipper tooth 02, the edge of the zipper tape 03 can be positioned within the first clearance groove 1331 to prevent the tape 03 from interfering with the installation of the zipper stop 01. It also prevents the first protrusion 133 from squeezing the edge of the tape 03 after the zipper stop 01 is installed, thus preventing wrinkles at the edge of the tape 03.

[0054] Similarly, the second protrusion 134 may have a second clearance groove 1341 on the side wall facing the first clamping opening N1. The second clearance groove 1341 is located between the first clamping part 11 and the second clamping part 12 and extends through the second protrusion 134 in a third direction. Based on this arrangement, the space inside the first clamping opening N1 can be increased, thereby providing sufficient space to accommodate other components. Optionally, when the zipper stop 01 is installed to the zipper tooth 02, the edge of the zipper tape 03 can be located in the second clearance groove 1341 to prevent the tape 03 from interfering with the installation of the zipper stop 01. Of course, it can also prevent the second protrusion 134 from squeezing the edge of the tape 03 after the zipper stop 01 is installed, thus preventing the edge of the tape 03 from wrinkling.

[0055] Optionally, the openings of the first clearance groove 1331 and the second clearance groove 1341 may be provided with rounded corners to reduce the probability of sharp edges causing injury to the user.

[0056] Based on the zipper stop 01 described above, this application also discloses a zipper assembly, which includes a pair of fabric tapes 03, zipper teeth 02, a zipper pull 04, and the zipper stop 01 described above, as shown in Figures 1 to 12.

[0057] Among them, the chain teeth 02 are connected to the inner edges of a pair of fabric strips 03, and the zipper head 04 is slidably connected to the chain teeth 02. When the zipper head 04 slides back and forth, the chain teeth 02 on each of the pair of fabric strips 03 can engage or disengage with each other; the zipper stop 01 is detachably sleeved on the chain teeth 02.

[0058] Based on the above settings, the zipper stop 01 and the zipper tooth 02 can be detachably coupled, allowing the zipper stop 01 to be installed on the corresponding zipper tooth 02 as needed, thereby adjusting the range of movement of the zipper head 04, meeting different user needs and improving user experience.

[0059] Referring to Figures 8 and 11, in some embodiments, the zipper tooth 02 may include a connecting seat 021 and an engaging head 022 located at the front end of the connecting seat 021. The connecting seat 021 is connected to the inner edges of a pair of fabric tapes 03 to ensure reliable connection between the zipper tooth 02 and the fabric tapes 03. The engaging head 022 protrudes from the fabric tape 03 on which the zipper tooth 02 is located and protrudes towards the fabric tape 03 on the other side. Thus, when the zipper pull 04 is pulled back and forth, the engaging heads 022 of corresponding zipper teeth 02 on the pair of fabric tapes 03 engage or disengage. Based on this configuration, the zipper can be opened by engaging the engaging heads 022 and opened by disengaging the engaging heads 022.

[0060] In some embodiments, when the stop body 10 is fitted onto the zipper tooth 02, the zipper tooth 02 extends beyond the receiving cavity M or is flush with the receiving cavity M along the first direction. Based on this, a stable engagement between the zipper tooth 02 and the zipper stop 01 can be ensured, preventing the zipper stop 01 from disengaging from the zipper tooth 02.

[0061] In addition, when the chain tooth 02 is flush with the receiving cavity M along the first direction, the thickness of the entire chain tooth 02 can be reduced, which can improve the user experience and the overall aesthetics of the chain tooth 02.

[0062] It should be noted that by the cooperation of the first clearance step 1131 and the second clearance step 1231 with the step structure 0241 on both sides of the tail 024 of the chain tooth 02, the chain tooth 02 can be flush with the receiving cavity M along the first direction.

[0063] Referring again to Figures 8 and 11, in some embodiments, the chain tooth 02 may further include a connecting neck 023 located between the connecting seat 021 and the engaging head 022. Along a third direction, the width of the connecting neck 023 is smaller than the width of both the connecting seat 021 and the engaging head 022, so that recesses 0231 are formed on opposite sides of the connecting neck 023 along the third direction. Based on this, the first protrusion 133 and the second protrusion 134 provided on the inner wall of the receiving cavity M of the zipper stop 01 can cooperate with the corresponding recesses 0231, thereby increasing the mating area between the zipper stop 01 and the chain tooth 02 and improving the stability of the mating.

[0064] In some embodiments, the chain tooth 02 may further include a tail 024, which is located at the tail end of the connecting seat 021 and connected to the inner edge of the fabric tape 03. Along the first direction, the two opposite sides of the tail 024 are respectively lower than the two opposite sides of the connecting seat 021, forming a stepped structure 0241. Based on this, when the zipper stop 01 is installed to the chain tooth 02, the first clearance step 1131 on the first horizontal arm 113 and the second clearance step 1231 on the second horizontal arm 123 of the zipper stop 01 can respectively cooperate with the corresponding stepped structure 0241. This achieves stable installation of the zipper stop 01 and also helps reduce the overall thickness of the zipper stop 01 after it cooperates with the chain tooth 02, thereby reducing the overall thickness of the zipper.

[0065] In some embodiments, the stop body 10 may be a component capable of elastic deformation to facilitate installation onto or removal from the chain teeth. Optionally, the stop body 10 may be a plastic part, a metal part, etc.

[0066] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
