Description

Technical Field

[0001] This utility model relates to the field of clothing accessories technology, and more specifically, to a zipper pull. It also relates to a zipper including the aforementioned zipper pull. Background Technology

[0002] Zippers are a widely used connecting accessory in clothing, bags and other products. The zipper pull is the core component that controls the opening and closing function. The zipper pull usually consists of a zipper body, a hook, and a zipper tab. By moving the zipper tab, the hook is raised or lowered, thereby unlocking and locking the zipper.

[0003] Currently, to achieve lightweight zipper pulls, holes are typically drilled in the metal tabs to reduce weight. However, this method has significant limitations: while drilling reduces overall weight, it cannot change the inherent volume and size of the tab, resulting in the zipper pull still appearing bulky and making it difficult to effectively reduce its weight.

[0004] Therefore, how to provide a slider structure that can effectively reduce weight while maintaining reliable locking function is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a zipper pull that can effectively reduce weight while maintaining a reliable locking function.

[0006] Another objective of this invention is to provide a zipper that includes the aforementioned zipper head.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A zipper puller includes:

[0009] The pull body has an internal cavity for the chain teeth to pass through;

[0010] The hook is oscillatingly mounted on the pull body and has a locking end, which is used to lock or unlock the chain teeth located in the inner cavity during oscillation;

[0011] A guide structure is provided on the pull body or the hook;

[0012] The pull tab includes a rope and a driving member disposed at one end of the rope. The driving member is movably disposed within the guide structure and moves within the guide structure by being pulled by the rope to drive the horse hook to swing.

[0014] Preferably, the driving member has a rolling part in the middle, the rolling part is housed in the guide groove, and the end of the rolling part abuts against the side wall of the guide groove along the width direction of the pull body, so that the side wall of the guide groove can restrict the displacement of the rolling part along the width direction of the pull body.

[0015] Preferably, the hook has a contact portion located outside the inner cavity, the contact portion being disposed opposite to the guide groove, and the two forming an active space that can accommodate the drive component.

[0016] Preferably, when the hook is in its natural state, the contact portion and the bottom of the guide groove together clamp the drive member to limit the displacement of the drive member in the direction perpendicular to the upper wing plate.

[0017] Preferably, the upper wing plate is provided with limiting protrusions on both sides of the contact portion along the width direction of the pull body, and the two ends of the driving member are provided with abutment portions. The two abutment portions are inserted into the two limiting protrusions respectively to limit the movement stroke of the driving member along the length direction of the pull body.

[0018] Preferably, the hook is provided with a limiting groove opposite to the guide groove. The limiting groove extends along the length direction of the pull body. A portion of the rolling part is accommodated in the limiting groove, and along the width direction of the pull body, the end of the portion abuts against the side wall of the limiting groove, so that the side wall of the limiting groove can restrict the displacement of the rolling part along the width direction of the pull body.

[0019] Preferably, the rolling part is a cylindrical structure and rolls in contact with the guide groove.

[0020] Preferably, the upper wing plate is provided with two sets of rivets spaced apart along the length of the pull body, and the two ends of the hook located outside the inner cavity are respectively movably engaged in the two sets of rivets.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] The core of this invention is to provide a zipper pull that can effectively reduce weight while maintaining a reliable locking function.

[0042] Another core aspect of this invention is providing a zipper that includes the aforementioned zipper head.

[0043] It should be noted that in this embodiment, the orientation or positional relationship indicated by "up", "down", "front", "back", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this application and simplifying the description, and is not intended to 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 on this application.

[0044] Please refer to Figures 1 to 7 This application provides a specific embodiment of a zipper puller, including a pull body 1, a hook 2, a guide structure 3, and a pull tab. The pull body 1 has an inner cavity 13 for the chain teeth to pass through; the hook 2 is oscillatingly mounted on the pull body 1 and has a locking end 21, which is used to lock or unlock the chain teeth located in the inner cavity 13 during oscillation; the guide structure 3 is mounted on the pull body 1 or the hook 2; the pull tab includes a rope 4 and a driving member 5 located at one end of the rope 4, the driving member 5 being movably mounted within the guide structure 3 and moving within the guide structure 3 by the pulling of the rope 4 to drive the hook 2 to oscillate.

[0045] In this embodiment, as Figure 1 or Figure 4 As shown, the pull body 1 includes an upper wing plate 11, a lower wing plate 12 and a connecting post. The upper wing plate 11 and the lower wing plate 12 are arranged opposite to each other and are connected by the connecting post to form an inner cavity 13 between them. The inner cavity 13 is used for the chain teeth to pass through.

[0046] The hook 2 is made of a flexible sheet material and is oscillatingly mounted on the zipper body 1. One end of the hook 2 is a locking end 21. When the hook 2 oscillates, the locking end 21 can extend into or out of the inner cavity 13 through the through hole 114 of the upper wing plate 11, thereby locking or unlocking the zipper teeth located therein, thus realizing the locking and unlocking of the zipper. It should be noted that the specific oscillation setting of the hook 2 on the zipper body 1 can be referred to in the prior art, which is not the focus of this application, and therefore will not be discussed in detail here.

[0047] like Figure 7 As shown, the pull tab consists of a flexible rope 4 and a driving member 5 located at one end of the rope 4. The driving member 5 is a block-shaped or shaft-shaped component with a certain rigidity and strength.

[0048] The guide structure 3 can be set on the tension body 1 (e.g.) Figure 5 As shown, for example, it is a groove on the upper wing plate 11 of the pull body 1 (i.e., the guide groove described below), or it can be provided on the hook 2 (not shown, for example, a groove-shaped structure formed by a protrusion on the hook 2).

[0049] like Figure 1 As shown, the driving component 5 of the pull tab is movably disposed within the guide structure 3. The user can pull the rope 4, and the driving component 5 can move within the path defined by the guide structure 3. The movement of the driving component 5 will contact and interact with the hook 2, thereby driving the hook 2 to swing.

[0050] In the above embodiment, the zipper head is applied to the zipper. In its natural state, the locking end 21 of the hook 2 swings downward under its own elasticity or additional elasticity (such as the elastic element between it and the zipper head), extends into the inner cavity 13 and gets stuck between the zipper teeth, so that the zipper head cannot move and the zipper is locked.

[0051] When the zipper needs to be opened, the user pulls the cord 4 of the zipper pull upwards. The drive component 5 moves forward within the guide structure 3, pushing the hook 2 to swing upwards against the elastic force. The locking end 21 then disengages from the chain teeth in the inner cavity 13, unlocking the zipper. When the zipper pull is released, the hook 2 returns to its original position under the action of the elastic force, causing the locking end 21 to re-enter the inner cavity 13 and automatically engage with the chain teeth, achieving automatic locking.

[0052] As described above, this application significantly reduces the weight and volume of the zipper pull (especially in the thickness direction) by replacing the traditional rigid pull tab with a rope body 4, thereby improving the comfort and aesthetics of the clothing. Furthermore, despite the lightweight structure of the zipper pull, the drive component 5 at one end of the rope body 4 can move within the guide structure 3. The user can pull the rope body 4, causing the hook 2 to swing, thus locking and unlocking the locking end 21 against the chain teeth. Therefore, while effectively reducing weight, the zipper pull still maintains a reliable automatic locking function.

[0053] It should also be noted that the flexible rope 4 can hang down naturally, which can avoid the problems of traditional pull tabs being prone to snagging, collision or accidental lifting, thus improving the safety and convenience of using the pull head.

[0054] Considering the specific configuration of guide structure 3, in specific embodiment one, as a preferred option, please refer to... Figure 3 The pull body 1 includes an upper wing plate 11, and the guide structure 3 is a guide groove provided on the upper wing plate 11, and the guide groove extends along the length direction of the pull body 1 (i.e. the zipper opening and closing direction).

[0055] By machining a guide groove in the upper wing plate 11, the extension direction of the guide groove is consistent with the length direction of the pull body 1, which can ensure that the drive component 5 always moves in a straight line along the zipper opening and closing direction, avoiding the offset of the drive component 5 and affecting the effective transmission of the user's pulling force to the direction required for the swing of the hook 2, thereby ensuring the normal locking and unlocking action of the hook 2.

[0056] Based on the above specific embodiment one, as a further preferred option, please refer to... Figure 1 The driving member 5 has a rolling part 51 in the middle. The rolling part 51 is housed in the guide groove, and the end of the rolling part 51 abuts against the side wall of the guide groove along the width direction of the pull body 1, so that the side wall of the guide groove can restrict the displacement of the rolling part 51 along the width direction of the pull body 1.

[0057] The width of the rolling part 51 is adapted to the width of the guide groove. By using the side wall of the guide groove to restrict the displacement of the rolling part 51 in the width direction of the pull body 1, the lateral swaying or misalignment of the drive member 5 during movement can be effectively prevented, ensuring the accuracy of transmission. Moreover, by setting the contact distribution between the drive member 5 and the guide groove as the rolling part 51, it is easy to see that the rolling contact between the drive member 5 and the guide groove through the rolling part 51 can reduce the motion resistance of the drive member 5, making the pulling operation more effortless and smoother.

[0058] Based on the above specific embodiment one, as a further preferred option, please refer to... Figure 1 The hook 2 is provided with a contact part 22 located outside the inner cavity 13. The contact part 22 is arranged opposite to the guide groove, and the two form an active space that can accommodate the drive member 5.

[0059] The contact portion 22 of the hook 2, located outside the inner cavity 13, is above and opposite the guide groove. This creates a movable space between the contact portion 22 of the hook 2 and the guide groove of the pull body 1, allowing the drive member 5 to be accommodated and move. This movable space effectively encloses the drive member 5, ensuring that it can contact the contact portion 22 of the hook 2 when moving, allowing the pulling force to be transmitted to the hook 2 to drive its swing, thus avoiding the risk of dislocation or failure.

[0060] Based on the above specific embodiment one, as a further preferred option, please refer to... Figure 1 When the hook 2 is in its natural state, the contact part 22 and the bottom of the guide groove together clamp the drive member 5 to limit the displacement of the drive member 5 in the direction perpendicular to the upper wing plate 11.

[0061] When the hook 2 is in its natural (unforced) state, this corresponds to the locked state of the zipper. The contact part 22 of the hook 2 presses down elastically, working together with the bottom of the guide groove to clamp the rolling part 51 located in the movable space from both above and below. This effectively limits the displacement of the drive component 5 in the direction perpendicular to the upper wing plate 11 (i.e., the thickness direction of the zipper head), preventing the drive component 5 from falling out of the movable space or wobbling up and down. This design achieves vertical limiting using the elasticity of the hook 2 itself, eliminating the need for additional pressure plates or cover plates, resulting in a simple structure.

[0062] Based on the above specific embodiment one, as a further preferred option, please refer to... Figure 1 and Figure 2 The upper wing plate 11 is provided with limiting protrusions 111 on both sides of the contact portion 22 along the width direction of the pull body 1. The two ends of the drive member 5 are provided with abutment portions 52. The two abutment portions 52 are inserted into the two limiting protrusions 111 respectively to limit the movement stroke of the drive member 5 along the length direction of the pull body 1.

[0063] The upper wing plate 11 has upwardly protruding limiting protrusions 111 on both sides of the contact portion 22 along the width direction of the pull body 1. The limiting protrusions 111 can adopt a structurally stable inverted U-shaped structure. Correspondingly, both ends of the rolling portion 51 are integrally connected with abutment portions 52 to form the two ends of the driving member 5. When the driving member 5 is installed, its rolling portion 51 is movably accommodated in the movable space, and the abutment portions 52 at both ends of the driving member 5 are respectively inserted into the channels formed by the corresponding two limiting protrusions 111.

[0064] Thus, by having the abutting portions 52 at both ends of the drive member 5 cooperate with the limiting protrusions 111 on the upper wing plate 11, the limit position of the drive member 5 moving back and forth in the guide groove can be determined, preventing the drive member 5 from being pulled out of the activity space or interfering with other components due to excessive pulling.

[0065] This application also provides a second specific embodiment, such as... Figure 5 As shown, its guide structure 3 is set in the same way as the guide structure 3 in specific implementation one. For further optimization, please refer to Figures 4 to 6The hook 2 is provided with a limiting groove 23 opposite to the guide groove. The limiting groove 23 extends along the length direction of the pull body 1. A part of the rolling part 51 is accommodated in the limiting groove 23. Along the width direction of the pull body 1, the end of the rolling part 51 accommodated in the limiting groove 23 abuts against the two side walls of the limiting groove 23, so that the side walls of the limiting groove 23 can restrict the displacement of the rolling part 51 along the width direction of the pull body 1.

[0066] When the user pulls the rope 4, the rolling part 51 of the drive component 5 rolls simultaneously within the channel formed by the guide groove of the pull body 1 and the limiting groove 23 of the hook 2. The sidewalls of both the limiting groove 23 and the guide groove are in contact with the rolling part 51, effectively limiting the displacement of the rolling part 51 in the width direction. This setting, by adding a limiting groove 23 to the hook 2 to enhance the limiting, can effectively prevent the lateral swaying or swinging of the drive component 5 during movement, ensuring efficient and accurate force transmission between the contact part 22 of the drive component 5 and the hook 2, thus avoiding jamming or failure due to misalignment.

[0067] Based on the above-described specific embodiment two, as a further preferred option, please refer to... Figure 4 and Figure 5 The upper wing plate 11 is provided with two sets of rivets at intervals along the length of the pull body 1. The two ends of the contact part 22 of the hook 2 located outside the inner cavity 13 are respectively movably engaged with the two sets of rivets.

[0068] The upper wing plate 11 of the pull body 1 is provided with a front riveting assembly 112 and a rear riveting assembly 113 at intervals along the length direction of the pull body 1. The two ends of the contact portion 22 of the hook 2 located outside the inner cavity 13 (that is, the front end and the rear end along the length direction of the pull body 1) are respectively movably engaged with the front riveting assembly 112 and the rear riveting assembly 113. Specifically, the front riveting body assembly 112 includes two front riveting bodies spaced apart along the width direction of the pull body 1. Each of the two front riveting bodies is fixed to the upper wing plate 11 by riveting and forms a suitable clamping space. The front end of the contact part 22 can swing and engage in the clamping space. The rear riveting body assembly 113 includes a rear riveting body. The rear end of the contact part 22 has an arc-shaped hollow groove 24. The rear riveting body is engaged in the hollow groove 24. When the hook 2 is in the natural state, that is, the zipper is in the locked state, the rear riveting body abuts against the end of the hollow groove 24 near the front riveting body (i.e., the upper end) and leaves a certain space between it and the end of the hollow groove 24 away from the front riveting body (i.e., the upper end) to avoid the rear riveting body interfering with the swing of the rear end of the contact part 22.

[0069] In the above-described installation structure, the two sets of rivets provide two fulcrums for the swing of the hook 2. When the drive unit 5 moves back and forth in the guide groove and pushes the contact part 22 of the hook 2, the hook 2 swings smoothly and stably with the front rivet group 112 as the axis. The rear rivet group 113 can determine the lowest position of the hook 2 and support the hook 2, thereby reliably controlling the rise and fall of the locking end 21 of the hook 2.

[0070] Based on any of the above embodiments, as a further preferred option, please refer to... Figure 7 The rolling part 51 is a cylindrical structure and rolls in contact with the guide groove.

[0071] A cylindrical rolling part 51 is housed within a guide groove in the upper wing plate 11, with its cylindrical outer surface in contact with the bottom and sidewalls of the guide groove. When the user pulls the rope 4, the cylindrical rolling part 51 transmits force by rolling within the guide groove, thereby driving the hook 2 to swing. During the pulling process, pure rolling or near-pure rolling motion occurs between the cylindrical rolling part 51 and the guide groove, reducing friction. This allows the user to easily pull the pull head with only a small amount of force.

[0072] Based on any of the above embodiments, as a further preferred option, please refer to... Figure 7 The pull tab also includes an injection-molded part 6 located at the other end of the rope body 4.

[0073] The injection-molded part 6 is firmly integrated with the end of the rope 4 through the injection molding process, forming a sturdy and easy-to-grip operating part. This allows the operator to apply force by gripping the injection-molded part 6 and pulling the rope 4, effectively transmitting the user's operating force through the rope 4 to the drive component 5, thereby driving the entire pull head to work. Therefore, the design of the injection-molded part 6 facilitates the user's grip and application of operating force, improving the convenience and comfort of operation.

[0074] Considering the specific configuration of the guide structure 3, in the third embodiment, as a preferred embodiment, the guide structure 3 is a groove-shaped structure that protrudes upward from the hook 2.

[0075] Specifically, in the portion of the hook 2 located outside the inner cavity 13, this portion protrudes upward to form a groove-like structure, and the groove-like structure extends along the length direction of the hook 2 (i.e., the length direction of the pull body 1). Its cross-section can be U-shaped or arc-shaped, and the driving member 5 of the pull tab (especially its rolling part 51) can be accommodated in the protruding groove. In this way, when the user pulls the rope 4, the driving member 5 can move within the groove-like structure formed by the hook 2 itself.

[0076] In this configuration, since the groove structure and the hook 2 are integrated, the drive component 5 moves directly within the groove, allowing the drag force to be transmitted to the hook 2 more directly and efficiently, reducing force loss. Furthermore, there is no need to machine guide grooves on the upper wing plate 11, simplifying the structure of the pull body 1 and reducing manufacturing costs.

[0077] This application also provides a zipper that includes the zipper pull provided in any of the above embodiments.
