Abstract
Description
Technical Field
[0001] This application belongs to the field of invisible zipper technology, and more specifically, relates to a zipper operating component and a zipper device. Background Technology
[0002] In traditional concealed zipper designs, the zipper pull is typically hidden inside the garment, operated only through an exposed pull tab. In existing technology, the locking function of the zipper pull primarily relies on the interaction between an elastic component and a locking hook. Specifically, when the pull tab is pulled, the elastic component deforms under pressure, causing the locking hook to disengage from the zipper teeth to unlock. When the pull tab is released, the elastic component springs back, pushing the locking hook downwards to engage the zipper teeth, thus achieving the locking function.
[0003] However, existing invisible zippers require pulling the hook upwards to unlock, which reduces the area covered by the zipper head and decreases the hook's strength. When the hook is subjected to large lateral or rotational forces, it is prone to deformation, slippage, or even breakage, resulting in a poor user experience. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to that other element.

Therefore, they should not be construed as limitations on this application.
[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0037] As described in the background section, in traditional concealed zipper designs, the zipper pull is typically hidden inside the garment, operated only by an exposed pull tab. In existing technology, the locking function of the zipper pull primarily relies on the interaction between an elastic component and a locking hook. Specifically, when the pull tab is pulled, the elastic component deforms under pressure, causing the locking hook to disengage from the zipper teeth to unlock. When the pull tab is released, the elastic component rebounds, pushing the locking hook downwards to engage the zipper teeth, thus achieving the locking function. However, existing concealed zippers require pulling the locking hook upwards to unlock, resulting in a reduced area of the zipper pull covering the locking hook. This decreases the hook's load-bearing capacity, making it prone to deformation, slippage, or even breakage under significant lateral or rotational forces, leading to a poor user experience.
[0038] See Figures 1 to 11As shown, to solve the above problems, according to one aspect of this application, an embodiment of this application provides a zipper operating component. The zipper operating component is used to open and close a zipper engaging component. The zipper operating component includes: a pull head 10, a locking part 20, and a locking hook limiting part 30. The pull head 10 includes a pull head body 11, on which a guide channel is provided. The zipper engaging component is slidably inserted into the guide channel. The locking part 20 includes a locking hook body 21, which is movably installed on the pull head body 11. The locking hook body 21 has a locked state in which it engages with the zipper engaging component in the guide channel to lock the zipper engaging component, and a separated state in which the zipper engaging component can be opened and closed. The lock hook limiting part 30 includes two lock hook limiting protrusions 31. The lock hook body 21 has a locking end 211 for engaging and locking the zipper engagement component. The two lock hook limiting protrusions 31 are spaced apart on the zipper head body 11 and are located on opposite sides of the locking end 211 in a first direction to limit the movement of the locking end 211 in the first direction. The first direction is perpendicular to the movement direction of the zipper head body 11 and parallel to the running plane of the zipper head body 11. A pull tab mounting cavity is formed between the lock hook body 21 and the zipper head body 11. When the lock hook body 21 is in the unlocked state, with the running plane as the height reference plane, the height of the lock hook limiting protrusion 31 is greater than or equal to the height of the side of the locking end 211 closest to the pull tab mounting cavity. The zipper operating component provided in this embodiment has two locking hook limiting protrusions 31 spaced apart on the zipper head body 11, with the two locking hook limiting protrusions 31 located on opposite sides of the locking end 211 in the first direction. This allows the zipper head 10 to restrict the movement of the locking end 211 in the first direction through the two locking hook limiting protrusions 31, preventing the locking end 211 from shifting or slipping when subjected to lateral or rotational forces. Since the height of the locking hook limiting protrusions 31 is set to be greater than or equal to the height of the side of the locking end 211 near the zipper mounting cavity when the locking hook body 21 is in the unlocked state, the locking hook limiting protrusions 31 provided in this embodiment can continuously and effectively support and limit the locking end 211, allowing the locking hook body 21 to withstand greater lateral forces, thereby effectively improving the reliability and service life of the zipper operating component.
[0039] It is understood that in this embodiment, the locking end 211 switches from the locked state to the unlocked state by moving away from the main body of the zipper. Therefore, when the zipper body 21 is switched to the unlocked state, the height of the locking end 211 is the maximum height of the locking end 211 during the operation of the zipper body 21. At this time, the height of the zipper limiting protrusion 31 is set to be greater than or equal to the height of the side of the locking end 211 near the zipper mounting cavity when the zipper body 21 is in the unlocked state. This ensures that the zipper limiting protrusion 31 can always effectively support and limit the locking end 211 during the operation of the zipper body 21.
[0040] It should be noted that, in this embodiment, the zipper engaging component refers to a separable closing component composed of two rows of interlocking zipper teeth and the connected fabric strip, which realizes the opening and closing function of the zipper engaging component by interlocking or separating; the running plane of the zipper head body 11 refers to the virtual plane that moves parallel to the zipper head body 11 during the pulling process, and this running plane is parallel to the plane where the fabric strip is located; the zipper tab mounting cavity refers to the spatial structure formed by the locking hook body 21 and the zipper head body 11, which is used to accommodate the connection part of the zipper tab mounting part 40.
[0041] It is understood that in some embodiments, the operating plane of the slider body 11 in this embodiment is the plane where the bottom of the slider body 11 is located. In this case, taking this operating plane as the height reference plane, the height of the locking hook limiting protrusion 31 is 'a', and the height of the locking end 211 near the slider mounting cavity is 'b', where a ≥ b. Here, the height of the locking hook limiting protrusion 31 in this embodiment refers to the vertical distance from the highest point of the locking hook limiting protrusion 31 to the height reference plane, and the height of the locking end 211 near the slider mounting cavity refers to the vertical distance from the highest point of the locking end 211 near the slider mounting cavity to the height reference plane.
[0042] See Figures 3 to 5 , Figure 7 , Figure 8 , Figure 10As shown, in a specific embodiment, the two locking hook limiting protrusions 31 in this embodiment include a first limiting protrusion and a second limiting protrusion; the locking hook limiting part 30 also includes a first reinforcing structure 32, which is at least partially disposed between the first limiting protrusion and the second limiting protrusion, and is connected to the first limiting protrusion and the second limiting protrusion respectively, for improving the structural strength of the first limiting protrusion and the second limiting protrusion. By setting a first reinforcing structure 32 between the first limiting protrusion and the second limiting protrusion, and connecting it to the first limiting protrusion and the second limiting protrusion respectively, the overall structural strength of the first limiting protrusion and the second limiting protrusion is effectively improved. Specifically, the setting of the first reinforcing structure 32 can establish a rigid connection between the first limiting protrusion and the second limiting protrusion, effectively improving the structural strength and deformation resistance of the first limiting protrusion and the second limiting protrusion. When the first limiting protrusion and / or the second limiting protrusion are subjected to a large lateral force, the rigidly connected first limiting protrusion and the second limiting protrusion can work together to make the lateral stress on the first limiting protrusion and / or the second limiting protrusion evenly distributed, avoiding local deformation or fracture caused by uneven force.
[0043] In some embodiments, the first reinforcing structure 32 in this embodiment includes a transverse connecting block. The transverse connecting block extends along a first direction, and its first end is connected to the side of the first limiting protrusion closest to the second limiting protrusion, while its second end is connected to the side of the second limiting protrusion closest to the first limiting protrusion. By providing a transverse connecting block between the first and second limiting protrusions and connecting it to both, the overall structural strength of the first and second limiting protrusions can be effectively improved.
[0044] In other embodiments, the first reinforcing structure 32 in this embodiment includes a transverse connecting rod. In this embodiment, the transverse connecting rod extends along a first direction, and its first end is connected to the side of the first limiting protrusion closest to the second limiting protrusion, while its second end is connected to the side of the second limiting protrusion closest to the first limiting protrusion. By providing a transverse connecting rod between the first and second limiting protrusions and connecting it to both, the overall structural strength of the first and second limiting protrusions can be effectively improved.
[0045] See Figure 10 and Figure 11As shown, in a specific embodiment, the locking hook limiting part 30 further includes a first riveting structure 35 and a second riveting structure 36. The first riveting structure 35 is disposed at one end of the first limiting protrusion away from the zipper head body 11, and the second riveting structure 36 is disposed at one end of the second limiting protrusion away from the zipper head body 11. When the locking hook body 21 is in the unlocked state, the first riveting structure 35 and / or the second riveting structure 36 abut against the side of the locking hook body 21 away from the zipper head body 11 and restrict the locking hook body 21 from moving in the direction away from the zipper head body 11. By providing a first riveting structure 35 at one end of the first limiting protrusion away from the swivel head body 11 and a second riveting structure 36 at one end of the second limiting protrusion away from the swivel head body 11, the swivel head 10 can rigidly abut against the side of the swivel head body 21 away from the swivel head body 11 through the first riveting structure 35 and / or the second riveting structure 36 when the swivel head body 21 is in the unlocked state. The first riveting structure 35 and / or the second riveting structure 36 can form a reliable mechanical limit, effectively preventing the swivel head body 21 from excessively displacing in the direction away from the swivel head body 11.
[0046] In some embodiments, the first riveting structure 35 includes a first riveting protrusion, and the second riveting structure 36 includes a second riveting protrusion. The first riveting protrusion is at least partially located on the side of the first limiting protrusion closest to the second limiting protrusion, and the second riveting protrusion is at least partially located on the side of the second limiting protrusion closest to the first limiting protrusion. When the lock hook body 21 is in the unlocked state, the pull head 10 can rigidly abut against the side of the lock hook body 21 away from the pull head body 11 via the first riveting protrusion and / or the second riveting protrusion, forming a reliable mechanical limit, thereby effectively preventing excessive displacement of the lock hook body 21 away from the pull head body 11. It should be noted that in this embodiment, the first riveting protrusion is formed by plastic deformation of the first riveting substrate, and the second riveting protrusion is formed by plastic deformation of the second riveting substrate. In some embodiments, the materials of the first and second riveting substrates in this embodiment are metal.
[0047] See Figures 5 to 7As shown, in a specific embodiment, the locking hook limiting part 30 further includes a second reinforcing structure 33 and a third reinforcing structure 34. The second reinforcing structure 33 is disposed on the side of the first limiting protrusion opposite to the second limiting protrusion, and is used to improve the structural strength of the first limiting protrusion. The third reinforcing structure 34 is disposed on the side of the second limiting protrusion opposite to the first limiting protrusion, and is used to improve the structural strength of the second limiting protrusion. By providing the second reinforcing structure 33 on the side of the first limiting protrusion opposite to the second limiting protrusion, the structural strength of the first limiting protrusion can be effectively improved, while avoiding interference between the second reinforcing structure 33 and the locking hook body 21. By providing the third reinforcing structure 34 on the side of the second limiting protrusion opposite to the first limiting protrusion, the structural strength of the second limiting protrusion can be effectively improved, while avoiding interference between the third reinforcing structure 34 and the locking hook body 21.
[0048] See Figure 7 As shown, in a specific embodiment, the second reinforcing structure 33 includes a first reinforcing protrusion. A first clearance gap is formed between the first reinforcing protrusion and the zipper pull body 11. The width of the first clearance gap is greater than or equal to the thickness of the zipper engagement component's fabric tape, used to allow clearance for the zipper engagement component's fabric tape. By setting a first clearance gap between the first reinforcing protrusion and the zipper pull body 11 with a width greater than or equal to the thickness of the zipper engagement component's fabric tape, interference between the first reinforcing protrusion and the zipper engagement component's fabric tape can be avoided. The width of the first clearance gap is c.
[0049] See Figure 7 As shown, in a specific embodiment, the third reinforcing structure 34 includes a second reinforcing protrusion. A second clearance gap is formed between the second reinforcing protrusion and the zipper pull body 11. The width of the second clearance gap is greater than or equal to the thickness of the zipper engagement component's fabric tape, used to allow clearance for the zipper engagement component's fabric tape. By setting a second clearance gap with a width greater than or equal to the thickness of the zipper engagement component's fabric tape between the second reinforcing protrusion and the zipper engagement component, interference between the second reinforcing protrusion and the zipper engagement component's fabric tape can be avoided. The width of the first clearance gap is d.
[0050] It is understood that the thickness of the first reinforcing protrusion and the second reinforcing protrusion in this embodiment is adjusted accordingly based on the height of the first limiting protrusion and the second limiting protrusion and the torsional resistance requirement of the locking hook body 21.
[0051] In other embodiments, the second reinforcing structure 33 in this embodiment includes a first reinforcing rib, and the third reinforcing structure 34 includes a second reinforcing rib. Both the first and second reinforcing ribs extend along a second direction, and a third clearance gap is formed between the first reinforcing rib and the zipper pull body 11, and a fourth clearance gap is formed between the second reinforcing rib and the zipper pull body 11. The widths of the third and fourth clearance gaps are both greater than or equal to the thickness of the zipper engagement component's fabric tape, used to allow clearance for the zipper engagement component's fabric tape. The second direction is perpendicular to the running plane. By providing the first and second reinforcing ribs extending along the second direction, the bending stiffness and torsional strength of the first and second limiting protrusions can be significantly improved.
[0052] In some embodiments, the second reinforcing structure in this embodiment includes a plurality of first reinforcing ribs, which are spaced apart along a third direction, wherein the third direction is perpendicular to the first and second directions. The third reinforcing structure includes a plurality of second reinforcing ribs, which are spaced apart along a third direction. By spaced apart the plurality of first and second reinforcing ribs, the bending stiffness and torsional strength of the first and second limiting protrusions can be further improved.
[0053] In one specific embodiment, the first reinforcing structure 32 is integrally formed with the first limiting protrusion and the second limiting protrusion. By setting the first reinforcing structure 32 to be integrally formed with the first limiting protrusion and the second limiting protrusion, the mechanical strength of the overall structure of the first reinforcing structure 32, the first limiting protrusion, and the second limiting protrusion can be effectively improved. It should be noted that, in this embodiment, the integral formation of the first reinforcing structure 32 with the first limiting protrusion and the second limiting protrusion means that the first reinforcing structure 32, the first limiting protrusion, and the second limiting protrusion are manufactured as a whole through the same processing step, forming an integral structure that cannot be disassembled.
[0054] In one specific embodiment, the second reinforcing structure 33 includes a first reinforcing protrusion, which is integrally formed with the first limiting protrusion. By making the first reinforcing protrusion integrally formed with the first limiting protrusion, the mechanical strength of the overall structure of the first reinforcing protrusion and the first limiting protrusion can be effectively improved. It should be noted that, in this embodiment, the integral forming of the first reinforcing protrusion and the first limiting protrusion means that the first reinforcing protrusion and the first limiting protrusion are manufactured as a whole through the same processing step, forming an integral structure that cannot be disassembled.
[0055] In one specific embodiment, the third reinforcing structure 34 includes a second reinforcing protrusion, which is integrally formed with the second limiting protrusion. By making the first reinforcing protrusion integrally formed with the first limiting protrusion, the mechanical strength of the overall structure of the second reinforcing protrusion and the second limiting protrusion can be effectively improved. It should be noted that, in this embodiment, the integral forming of the second reinforcing protrusion and the second limiting protrusion means that the second reinforcing protrusion and the second limiting protrusion are manufactured as a whole through the same processing step, forming a non-removable integral structure.
[0056] See Figure 1 and Figure 2 As shown, in one specific embodiment, the locking part 20 further includes an elastic element 22. The elastic element 22 is installed on the zipper pull body 11 and abuts against the hook body 21, and is used to apply a spring force to the hook body 21, so that the hook body 21 can maintain the locked state through the spring force when it is not subjected to external force. By providing an elastic element 22 on the zipper pull body 11 that abuts against the hook body 21, the zipper operating component can maintain the locked state of the hook body 21 through the spring force applied to the hook body 21 by the elastic element 22 when the hook body 21 is not subjected to external force. It should be noted that in some embodiments, the elastic element 22 in this embodiment includes an elastic sheet, such as a U-shaped metal elastic sheet, a U-shaped plastic elastic sheet, etc. Of course, in other embodiments, the elastic element 22 in this embodiment may also include other components that can apply a spring force to the hook body 21, such as a compression spring.
[0057] See Figure 1 and Figure 2 As shown, in a specific embodiment, the locking hook body 21 is slidably mounted on the zipper head body 11 in a direction perpendicular to the operating plane. The elastic element 22 abuts against the side of the locking hook body 21 away from the zipper head body 11, and is used to apply a spring force toward the zipper head body 11 to the locking hook body 21. By slidably mounting the locking hook body 21 on the zipper head body 11 in a direction perpendicular to the operating plane, and making the elastic element 22 abut against the side of the locking hook body 21 away from the zipper head body 11, the zipper operating component can maintain the locking state of the locking hook body 21 by the spring force applied to the locking hook body 21 by the elastic element 22 when the locking hook body 21 is not subjected to external force.
[0058] In another embodiment, the locking hook body 21 is pivotally connected to the zipper pull body 11. The locking hook body 21 has an abutment end, and the pivot axis of the locking hook body 21 is located between the abutment end and the locking end 211. The elastic member 22 abuts against the abutment end and applies a spring force away from the zipper pull body 11 to the abutment end. By pivotally connecting the locking hook body 21 to the zipper pull body 11 and abutting the elastic member 22 against the abutment end of the locking hook body 21, the zipper operating component can maintain the locking state of the locking hook body 21 by the spring force applied to the locking hook body 21 by the elastic member 22 when the locking hook body 21 is not subjected to external force.
[0059] See Figures 1 to 4 As shown, in one specific embodiment, the zipper operating component further includes a pull tab 40, which is at least partially installed in the pull tab mounting cavity. When the pull tab 40 is pulled in a direction away from the zipper head body 11, the pull tab 40 can abut against the locking hook body 21 and drive the locking hook body 21 from a locked state to an unlocked state. By at least partially installing the pull tab 40 in the pull tab mounting cavity, the zipper operating component can pull the locking hook body 21 in a direction away from the zipper head body 11 by pulling the pull tab 40 in a direction away from the zipper head body 11, thereby overcoming the elastic force applied by the elastic member 22 and moving it in a direction away from the zipper head body 11, thus switching the locking hook body 21 from a locked state to an unlocked state. It is understood that the specific structure of the pull tab 40 in this embodiment is a conventional structure in the prior art and will not be described in detail here.
[0060] According to another aspect of this application, a zipper device is provided, the zipper device including a zipper operating component and a zipper engaging component, wherein the zipper operating component is the aforementioned zipper operating component.
[0061] In summary, the zipper operating component and zipper device provided in this embodiment have at least the following beneficial technical effects: The zipper operating component provided in this embodiment provides two locking hook limiting protrusions 31 spaced apart on the zipper head body 11, and the two locking hook limiting protrusions 31 are respectively located on opposite sides of the locking end 211 in the first direction. This allows the zipper head 10 to restrict the movement of the locking end 211 in the first direction through the two locking hook limiting protrusions 31, preventing the locking end 211 from shifting or slipping when subjected to lateral or rotational forces. Since the height of the locking hook limiting protrusions 31 is set to be greater than or equal to the height of the side of the locking end 211 near the zipper tab mounting cavity when the locking hook body 21 is in the unlocked state, the locking hook limiting protrusions 31 provided in this embodiment can continuously and effectively provide support and limiting for the locking end 211, allowing the locking hook body 21 to withstand greater lateral forces, thereby effectively improving the reliability and service life of the zipper operating component.
[0062] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
