Description

Technical Field

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

[0002] Traditional zipper pulls typically incorporate caps and alloy tabs to facilitate the connection with the pull cord. While these additional structures meet basic connection requirements, they significantly increase the overall weight of the zipper pull, making it unsuitable for today's functional clothing with stringent lightweight requirements. Furthermore, the design of the contact points between traditional zipper pulls and the pull cord is flawed; the lever point where the pull cord contacts the zipper pull is often located far from the zipper pull's axis. When the pull cord is pulled, the zipper pull is prone to tipping back and forth due to unbalanced force. This not only increases pulling resistance and causes a jerky pulling experience but can also accelerate wear on the zipper pull and zipper teeth, affecting the zipper's lifespan. Utility Model Content

[0003] Therefore, it is necessary to provide a zipper head, zipper head assembly, and zipper to address the above problems, thereby achieving lightweight zipper head, reducing the back-and-forth flipping phenomenon during pulling, and improving the smoothness of the pull.

[0004] This utility model first provides a pull head for cooperating with a pull cord, including a first mating member, a second mating member, and a connecting member disposed between the first mating member and the second mating member, which are spaced apart along the thickness direction of the pull head. The pull head has a through hole extending along the thickness direction for passing the pull cord through. The end of the first mating member and / or the second mating member away from the connecting member has a limiting groove, which communicates with the through hole and extends along the length direction of the pull head.

[0005] With this configuration, the first and second mating parts are directly connected by a connector, simplifying the overall structure, reducing the number of parts in the slider, and achieving a lightweight design. The through hole provides a passage for the pull rope, allowing the pull rope to be stably connected to the slider. The limiting groove is connected to the through hole and extends along the length of the slider, which can limit the lateral displacement of the pull rope relative to the slider, making the lever point where the pull rope contacts the slider closer to the axis of the slider. When the pull rope is pulled, the flipping torque on the slider is reduced, effectively reducing the phenomenon of forward and backward flipping.

[0006] In one embodiment, the limiting groove extends from the through hole toward the center of the pull head.

[0007] With this design, the limiting groove extends from the through hole towards the center of the pull head, which can guide the pull rope to move closer to the center of the pull head, further shortening the distance from the contact point between the pull rope and the pull head to the axis of the pull head, reducing the torque when pulling, and lowering the probability of the pull head flipping.

[0008] In one embodiment, from the through hole to the center of the pull head, the bottom wall of the limiting groove is inclined away from the connector.

[0009] With this design, the bottom wall of the limiting groove is inclined from the through hole toward the center of the pull head, and the inclination direction is away from the connecting part, forming a guide surface with a slope. The inclined design allows the pull rope to be gradually guided and pressed along the inclined bottom wall when it is pulled into the limiting groove.

[0010] In one embodiment, the limiting groove extends from the through hole toward the edge of the pull head.

[0011] This design sets the extension direction of the limiting groove to the edge of the pull head from the through hole, allowing the main body or end of the pull rope to be guided to the outer area of ​​the pull head after passing through the through hole and entering the limiting groove, providing a more open or easier-to-operate fixing method for the pull rope.

[0012] In one embodiment, the bottom wall of the limiting groove is parallel to the length direction of the pull head.

[0013] With this design, the bottom wall is parallel to the length direction of the pull head, allowing the pull rope to slide smoothly along the length direction of the pull head after being embedded in the limiting groove. This reduces the frictional resistance between the pull rope and the side wall of the limiting groove, while ensuring that the force direction of the pull rope is consistent with the movement direction of the pull head, thus improving pulling efficiency.

[0014] In one embodiment, the connector includes an abutment portion extending to the edge of the pull head and corresponding to the limiting groove.

[0015] With this configuration, when the pull rope passes through the through hole and enters the limiting groove, the abutting part can act as an additional support or limiting surface, together with the limiting groove, to form multi-point or multi-faceted support for the pull rope.

[0016] This utility model also provides a pull head assembly, including a pull cord and the aforementioned pull head.

[0017] With this design, the component fully utilizes the advantages of the zipper head in terms of lightweight, dual-sided operation, and rope fixation, achieving a seamless connection between the zipper head and rope, stable and reliable operation, and convenient operation.

[0018] In one embodiment, the limiting groove extends from the through hole toward the center of the pull head, and the pull rope passes through the through hole and is limited and engaged with the limiting groove.

[0019] With this design, in the zipper assembly, the limiting groove extends toward the center of the zipper and forms a limiting engagement with the pull cord passing through the through hole, so that the main body or end of the pull cord can be effectively stored and fixed inside the zipper, thereby minimizing the exposure and swaying of the pull cord to the outside.

[0020] In one embodiment, the limiting groove extends from the through hole toward the edge of the pull head, the pull rope includes a free end and a connecting end with a through hole, the free end passes through the through hole and the through hole in sequence, and the connecting end is limited and engaged with the limiting groove.

[0021] With this configuration, the free end passes through the through hole and the through hole on the connecting end in sequence, and the connecting end is matched with the limiting groove to form a ring or closed connection structure, which ensures the overall stability of the pull rope.

[0022] This utility model also provides a zipper, including the above-mentioned zipper pull assembly.

[0023] With this design, the zipper integrates the aforementioned zipper pull assembly into the zipper system. The lightweight design of the zipper pull and the stable cooperation of the drawstring make the zipper more suitable for lightweight functional clothing. At the same time, the zipper pull assembly, with its stable positioning and smooth operation, ensures that the zipper opens and closes freely. Attached Figure Description

[0035] Traditional zipper pulls typically incorporate caps and alloy tabs to facilitate the connection with the pull cord. While these additional structures meet basic connection requirements, they significantly increase the overall weight of the zipper pull, making it unsuitable for today's functional clothing with stringent lightweight requirements. Furthermore, the design of the contact points between traditional zipper pulls and the pull cord is flawed; the lever point where the pull cord contacts the zipper pull is often located far from the zipper pull's axis. When the pull cord is pulled, the zipper pull is prone to tipping back and forth due to unbalanced force. This not only increases pulling resistance and causes a jerky pulling experience but can also accelerate wear on the zipper pull and zipper teeth, affecting the zipper's lifespan.

[0036] To solve the above problems, such as Figures 1 to 4 As shown, this application provides a zipper head, a zipper head assembly, and a zipper to achieve lightweight zipper head and reduce the back-and-forth flipping phenomenon during pulling, thereby improving the smoothness of the pull.

[0037] like Figure 1 As shown, the Z-axis is the thickness direction of the slider, and the X-axis is the length direction of the slider.

[0038] like Figure 1 and Figure 2 As shown, this application first provides a pull head for cooperating with a pull cord 200; the pull head includes a first mating member 1, a second mating member 2 and a connecting member 3 disposed between the first mating member 1 and the second mating member 2, which are spaced apart along the thickness direction of the pull head; the pull head is provided with a through hole 4 extending along the thickness direction, the through hole 4 is used to pass through the pull cord 200; the first mating member 1 and the second mating member 2 are provided with a limiting groove 5 at the end away from the connecting member 3, the limiting groove 5 communicates with the through hole 4 and extends along the length direction of the pull head.

[0039] With this configuration, the first mating part 1 and the second mating part 2 are directly connected via the connecting part 3, eliminating the need for the traditional zipper cap and alloy pull tab. This simplifies the overall structure, reduces the number of parts in the zipper, and thus lowers the weight of the zipper, achieving a lightweight design that is more suitable for lightweight functional clothing. The through hole 4 provides a passage for the pull cord 200, allowing it to be stably connected to the zipper. The limiting groove 5 communicates with the through hole 4 and extends along its length. After the pull cord 200 passes through the through hole 4, a portion of the pull cord 200 can be embedded in the limiting groove 5. The limiting groove 5 restricts the lateral displacement of the pull cord 200 relative to the zipper, making the lever point of contact between the pull cord 200 and the zipper closer to the axis of the zipper. When the pull cord 200 is pulled, the flipping torque on the zipper is reduced, effectively reducing the back-and-forth flipping phenomenon, thereby reducing pulling resistance and improving the smoothness of the pull.

[0040] The size of the limiting groove 5 can be adjusted according to the diameter of the pull rope 200. For example, for a thicker pull rope 200, the width and depth of the limiting groove 5 can be appropriately increased to ensure that the pull rope 200 can enter smoothly and be effectively limited; for a thinner pull rope 200, the size of the limiting groove 5 can be reduced to improve the limiting accuracy; the shape of the limiting groove 5 can also be optimized according to the cross-sectional shape of the pull rope 200 it is used with, such as a U-shaped, V-shaped, rectangular or circular groove, to achieve a tighter fit and a stronger limiting effect.

[0041] In another embodiment, the first mating part 1 and the second mating part 2 can be two independent structural parts, which are fixedly connected to the connecting part 3 by means of welding, riveting, bolting or snap-fit ​​connection.

[0042] In another embodiment, one of the first mating parts 1 and the second mating parts 2 is provided with a limiting groove 5 at the end away from the connecting part 3. The limiting groove 5 is connected to the through hole 4 and extends along the length direction of the pull head. As long as the pull rope 200 can be limited by the limiting groove 5, it is acceptable.

[0043] The center of the through hole 4 can be set on the center line of the slider, or it can be set slightly off from the center line according to actual design requirements.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment, the limiting groove 5 extends from the through hole 4 toward the center of the slider. This arrangement, with the limiting groove 5 extending from the through hole 4 toward the center of the slider, guides the pull cord 200 toward the center of the slider, further shortening the distance from the contact point between the pull cord 200 and the slider's axis, reducing the torque during pulling, lowering the probability of the slider tip tipping over, and improving pulling stability. Simultaneously, setting the extension direction of the limiting groove 5 from the through hole 4 toward the center of the slider ensures that after the pull cord 200 passes through the through hole 4 and enters the limiting groove 5, its main body or end can be guided into the internal area of ​​the slider. This design helps to more tightly house the pull cord 200 within the main structure of the slider, reducing the possibility of the pull cord 200 protruding outwards or swinging, thereby reducing the risk of the pull cord 200 being accidentally hooked, tangled, or damaged during use, and improving the overall compactness and safety of the slider.

[0045] In the illustrated embodiment, a single pull rope 200 passes through the through hole 4, and the pull rope 200 is limited and engaged with the bottom wall of the limiting groove 5 extending toward the center of the pull head.

[0046] In another implementation, depending on the actual application scenario, other rope threading methods can be adopted, such as the double-strand pull rope 200 passing through the through hole 4 and being limited and engaged with the bottom or side wall of the limiting groove 5 extending toward the center of the pull head.

[0047] like Figure 1 and Figure 3 As shown, in one embodiment, the bottom wall of the limiting groove 5, from the through hole 4 to the center of the pull head, slopes away from the connecting member 3. This arrangement, with the bottom wall of the limiting groove 5 sloping away from the connecting member 3 from the through hole 4 towards the center of the pull head, creates a sloping guide surface. This inclined design allows the pull rope 200 to be gradually guided and compressed along the inclined bottom wall when pulled into the limiting groove 5. When the pull rope 200 is under tension, its contact with the inclined bottom wall generates a component force perpendicular to the bottom wall, further pushing the pull rope 200 towards the side wall or top wall of the limiting groove 5, thus forming a tighter compression fit. This self-locking or self-tightening principle effectively enhances the stability of the pull rope 200 within the limiting groove 5, preventing loosening or detachment even under frequent pulling or large external forces, significantly improving the reliability of the pull head.

[0048] The tilt angle of the bottom wall of the limiting groove 5 is adjustable. For example, increasing the tilt angle can enhance the component force and further improve the stability of the pull rope 200, but may reduce the effective length of the limiting groove 5; decreasing the angle has the opposite effect.

[0049] In another embodiment, the bottom wall of the limiting groove 5 can be designed as multi-segment inclined or curved inclined to provide a more precise guiding and limiting effect for the pull rope 200.

[0050] In another embodiment, from the through hole 4 to the center of the pull head, the bottom wall of the limiting groove 5 is inclined towards the connecting member 3.

[0051] In another embodiment, the bottom wall of the limiting groove 5 is parallel to the length direction of the pull head.

[0052] In another embodiment, the limiting groove 5 can extend from the through hole 4 to the center of the slider and further to the edge of the slider.

[0053] like Figures 1 to 3 As shown, in one embodiment, the limiting groove 5 extends from the through hole 4 toward the edge of the swivel head. This arrangement, with the limiting groove 5 extending from the through hole 4 toward the edge of the swivel head, allows the main body or end of the pull cord 200 to be guided to the outer area of ​​the swivel head after passing through the through hole 4 and entering the limiting groove 5. This design provides a more open or easier-to-operate securing method for the pull cord 200. For example, this edge-extending limiting groove 5 provides convenience when quick replacement of the pull cord 200 is required, or when the pull cord 200 needs to be partially exposed for other operations such as attaching decorations or identification tags; simultaneously, the limiting groove 5 extending from the through hole 4 toward the edge of the swivel head also limits the tendency of the pull cord 200 to protrude outwards or swing when pulled in the opposite direction.

[0054] In the illustrated embodiment, the two free ends 201 of the pull rope 200 pass through the through hole 4 and the through hole 2021 in sequence. The pull rope 200 is in sequence limited and engaged with the bottom wall of the abutment part 31 and the limiting groove 5. The connecting end 202 of the pull rope 200 is in limited and engaged with the side wall of the limiting groove 5 extending toward the edge of the pull head.

[0055] In another implementation, depending on the actual application scenario, other rope threading methods can be adopted, such as the double-strand pull rope 200 passing through the through hole 4 and being limited and engaged with the bottom wall or side wall of the limiting groove 5 extending toward the edge of the pull head.

[0056] like Figure 1 As shown, in one embodiment, the bottom wall of the limiting groove 5 is parallel to the length direction of the pull head. This arrangement, with the bottom wall parallel to the length direction of the pull head, allows the pull rope 200 to slide smoothly along the length direction of the pull head after being embedded in the limiting groove 5, reducing the frictional resistance between the pull rope 200 and the side wall of the limiting groove 5. Simultaneously, it ensures that the force direction of the pull rope 200 is consistent with the movement direction of the pull head, improving pulling efficiency. Furthermore, the parallel bottom wall facilitates processing, ensuring dimensional accuracy and surface quality, and improving the overall quality of the pull head.

[0057] In another embodiment, the bottom wall of the limiting groove 5 can be designed as a multi-segment structure. For example, the segmented bottom wall can adapt to the bending deformation of the pull rope 200, with each segment conforming to the local shape of the pull rope 200, dispersing pressure, preventing local indentations from causing the pull rope 200 to break, and extending its service life.

[0058] In another embodiment, from the through hole 4 to the center of the pull head, the bottom wall of the limiting groove 5 is inclined towards the connecting member 3.

[0059] In another embodiment, from the through hole 4 to the center of the pull head, the bottom wall of the limiting groove 5 is inclined away from the connecting member 3.

[0060] like Figure 1 and Figure 2 As shown, in one embodiment, the connecting member 3 includes an abutment portion 31 extending to the edge of the pull head and corresponding to the limiting groove 5. This arrangement, where the connecting member 3 extends to the edge of the pull head and forms the abutment portion 31, and this abutment portion 31 corresponds to the limiting groove 5, means that the connecting member 3 not only functions to connect the first mating member 1 and the second mating member 2, but also directly participates in the limiting and fixing of the pull rope 200. When the pull rope 200 passes through the through hole 4 and enters the limiting groove 5, the abutment portion 31 can act as an additional support or limiting surface, working together with the limiting groove 5 to provide multi-point or multi-faceted support for the pull rope 200. This design enhances the fixing strength and stability of the pull rope 200, especially when the pull rope 200 is subjected to lateral or torsional forces, the abutment portion 31 can effectively prevent the pull rope 200 from coming out of the limiting groove 5.

[0061] The contact surface between the contact part 31 and the pull rope 200 can be designed as a plane to provide uniform support and limit the pull rope 200, ensuring long-term stable cooperation.

[0062] In another embodiment, the shape of the contact surface between the abutment portion 31 and the pull rope 200 can be designed according to actual needs. For example, it can be designed as an arc that matches the cross-sectional shape of the pull rope 200, providing uniform support and limiting, preventing the pull rope 200 from being deformed by pressure, maintaining elasticity and strength, and ensuring long-term stable cooperation.

[0063] This utility model also provides a zipper pull assembly, including a pull cord 200 and the aforementioned zipper pull. With this configuration, the zipper pull assembly combines the pull cord 200 with the aforementioned zipper pull to form a complete and functionally optimized zipper operating unit. This assembly fully utilizes the advantages of the zipper pull in terms of lightweight design, double-sided operation, and the secure attachment of the pull cord 200, achieving immediate use, stable and reliable fit, and convenient operation for both the zipper pull and pull cord 200. The tight fit between the pull cord 200 and the zipper pull ensures that it will not easily fall off or slip during use, improving the overall user experience and product durability.

[0064] like Figure 1 and Figure 2 As shown, in one embodiment, the pull cord 200 passes through the through hole 4 and engages with a limiting groove 5 extending towards the center of the slider head. In the illustrated embodiment, a single pull cord 200 passes through the through hole 4, and the pull cord 200 engages with the bottom wall of the limiting groove 5 extending towards the center of the slider head. This configuration, in the slider assembly, allows the limiting groove 5 to extend towards the center of the slider head and engage with the pull cord 200 passing through the through hole 4, effectively storing and securing the main body or end of the pull cord 200 inside the slider head, thereby minimizing the exposure and movement of the pull cord 200 externally. This design enhances the overall compactness and safety of the slider assembly, reducing the risk of the pull cord 200 being hooked or entangled by external objects. The tight engagement between the pull cord 200 and the limiting groove 5 ensures that the pull cord 200 will not slide freely within the through hole 4 during pulling, providing a stable and reliable grip point and improving the accuracy and comfort of operation.

[0065] like Figure 1 , Figure 3 and Figure 4As shown, in one embodiment, the pull cord 200 includes a free end 201 and a connecting end 202 with a through hole 2021. The free end 201 passes through the through hole 4 and the through hole 2021 in sequence, and the connecting end 202 engages with a limiting groove 5 extending toward the edge of the pull head. The free end 201 of the pull cord 200 passes through the through hole 4 and the through hole 2021 in sequence, and the pull cord 200 engages with the bottom wall of the abutment portion 31 and the limiting groove 5 in sequence. The connecting end 202 of the pull cord 200 engages with the side wall of the limiting groove 5 extending toward the edge of the pull head. The through hole 2021 can be formed by folding the two free ends 201 of the pull cord 200 together, or it can be located on one free end 201. This arrangement, with the limiting groove 5 extending toward the edge of the pull head assembly, provides a more flexible and open way to connect the pull cord 200. The pull rope 200 is designed to have a free end 201 and a connecting end 202, wherein the connecting end 202 is provided with a through hole 2021. The free end 201 passes through the through hole 4 and the through hole 2021 on the connecting end 202 in sequence, and then the connecting end 202 is engaged with the limiting groove 5 to form a ring-shaped or closed connection structure, which ensures the overall stability of the pull rope 200.

[0066] This utility model also provides a zipper, including the aforementioned zipper pull assembly. Specifically, the zipper also includes zipper teeth, and the reciprocating movement of the zipper pull assembly along the length of the zipper pull enables the zipper teeth to engage or disengage. With this configuration, the zipper integrates the aforementioned zipper pull assembly into the zipper system. The lightweight design of the zipper pull and the stable engagement of the pull cord 200 make the zipper more suitable for lightweight functional clothing. Simultaneously, the zipper pull assembly, with its stable limiting and smooth operation, ensures that the zipper opens and closes freely, meeting the basic functional requirements of closure components in clothing, bags, and other fields, and ensuring the convenience of closing and opening items.

[0067] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application.
