Description

Technical Field

[0001] This application belongs to the technical field of zipper pulls, zippers, etc., and specifically relates to a zipper pull and an article with zipper teeth. Background Technology

[0002] Some zipper pulls in related technologies have their upper and lower plate edges aligned, giving the pull a symmetrical appearance. While this type of zipper pull looks more uniform, it is bulky, hindering miniaturization and weight reduction. Furthermore, the larger contact area between the zipper pull and the fabric results in greater frictional resistance during pulling, requiring users to apply more force and leading to a poor user experience. Utility Model Content

[0003] The purpose of this application is to provide a zipper pull and an article with chain teeth, which can solve the problems of large zipper pull size, which is not conducive to miniaturization and lightweight development, and increased pulling resistance.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows: This application provides a zipper puller, including: an upper plate structure, a lower plate structure, and a connecting post; The upper plate structure and the lower plate structure are spaced apart in the vertical direction. The connecting post is connected between the upper plate structure and the lower plate structure and is located at the front end of the pull head. The upper plate structure, the lower plate structure and the connecting post form a receiving space for the chain to pass through in the front-back direction. Along the vertical direction, the projected area of ​​the upper plate structure is smaller than that of the lower plate structure, and there are gaps between the left and right ends of the upper plate structure and the left and right ends of the lower plate structure that are insufficient to disengage the chain belt.

[0005] This application embodiment also provides an article with chain teeth, the article comprising: a pair of chain straps and the aforementioned zipper pull; The pair of chain belts are provided with a plurality of chain teeth, and the pull head is movably disposed on the pair of chain belts so that the chain teeth of the pair of chain belts can engage or disengage; The gap is smaller in the vertical direction than the thickness of the portion of the chain belt located within the receiving space, and the gap is smaller in the horizontal direction than the width of the portion of the chain belt located within the receiving space.

[0006] In this embodiment of the zipper pull, while enabling the engagement or disengagement of the chain teeth, the projected area of ​​the upper plate structure is smaller than that of the lower plate structure in the vertical direction. This reduces the overall volume of the zipper pull, allowing it to be miniaturized and lightweight, saving materials and reducing costs. Furthermore, the size of the upper plate structure is closer to the size of the chain teeth, achieving a near-invisible effect and improving its appearance. The reduced contact area between the smaller upper plate structure and the fabric on both sides is also reduced, even to the point of detachment. This reduces or eliminates the resistance from the fabric when pulling the zipper pull, thus reducing friction and making it easier for the user to pull the zipper pull, improving the user experience. Additionally, the chain cannot pass through the gaps between the left and right ends of the upper and lower plate structures, ensuring that the chain and zipper pull remain connected and allowing the zipper pull to move stably on the chain.

Detailed Implementation

[0009] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

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

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

[0012] refer to Figures 1 to 12 This application discloses a zipper puller 01, which includes an upper plate structure 10, a lower plate structure 20, and a connecting post 30.

[0013] The upper plate structure 10 and the lower plate structure 20 are spaced apart in the vertical direction. Optionally, the upper plate structure 10 and the lower plate structure 20 can be parallel to each other or not parallel, depending on the actual working conditions.

[0014] The connecting post 30 connects the upper plate structure 10 and the lower plate structure 20, and is located at the front end of the pull head 01. Optionally, one end of the connecting post 30 can be fixed to the side of the upper plate structure 10 facing the lower plate structure 20, and the other end of the connecting post 30 can be fixed to the side of the lower plate structure 20 facing the upper plate structure 10. Exemplarily, the connecting post 30 can be fixedly connected to the upper plate structure 10 and the lower plate structure 20, such as by welding or bonding, or it can be detachably connected, such as by plugging or snapping. Of course, the connecting post 30, the upper plate structure 10, and the lower plate structure 20 can also be integrated as a whole, depending on the actual working conditions.

[0015] Based on the above configuration, the upper plate structure 10, the lower plate structure 20 and the connecting column 30 can form a receiving space M, which is used to pass through the chain belt 02 in the front-back direction so that the pull head 01 can move along the extension direction of the chain belt 02 (i.e., the front-back direction), thereby realizing the engagement or disengagement of the chain teeth 021 on the chain belt 02.

[0016] In this embodiment, the projected area of ​​the upper plate structure 10 can be smaller than the projected area of ​​the lower plate structure 20 along the vertical direction. Based on this, in this embodiment, the zipper pull 01, while still enabling the engagement or disengagement of the chain teeth 021, can reduce the overall volume of the zipper pull 01 by decreasing the size of the upper plate structure 10. This allows the zipper pull 01 to move towards miniaturization and lightweight design, saving materials and reducing costs. Furthermore, the size of the upper plate structure 10 can be made closer to the size of the chain teeth 021, achieving a near-invisible effect and making the upper plate structure 10 appear less obtrusive, thus improving the appearance of the zipper pull 01.

[0017] Furthermore, the reduced contact area between the scaled-down upper plate structure 10 and the fabrics on the left and right sides is reduced, or even detached from the fabrics on the sides. Thus, when the slider 01 is pulled, the obstruction effect of the fabrics on the upper plate structure 10 can be reduced or even eliminated, that is, the frictional resistance is reduced, making it easier for the user to pull the slider 01 and improve the user experience.

[0018] In addition, there is a gap N between the left and right ends of the upper plate structure 10 and the left and right ends of the lower plate structure 20 that is not large enough to disengage the chain belt 02. In this way, the chain belt 02 and the pull head 01 will not disengage, and the pull head 01 can move stably on the chain belt 02.

[0019] refer to Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 10In some embodiments, the lower plate structure 20 may include a bottom plate 21, a left side plate 22, and a right side plate 23. The left side plate 22 and right side plate 23 are respectively located at both ends of the bottom plate 21 in the left-right direction and extend towards the upper plate structure 10, thus forming a concave groove together with the bottom plate 21. Optionally, the connecting post 30 may be located in the concave groove and positioned at the front end of the bottom plate 21.

[0020] Along the vertical direction, the projection of the upper plate structure 10 can be located within the projection of the bottom plate 21, and there are gaps N between the left and right ends of the upper plate structure 10 and the left side plate 22 and the right side plate 23, respectively. Based on this, when the chain 02 passes through the zipper 01, the chain teeth 021 of the chain 02 are located within the receiving space M, while the fabric 022 of the chain 02 extends beyond the receiving space M through the gaps N. Therefore, by setting the gaps N, clearance space can be provided for the fabric 022 to ensure that the zipper 01 can move smoothly along the extension direction of the chain 02.

[0021] In some embodiments, the gap N has a dimension smaller in the vertical direction than the thickness of the portion of the chain belt 02 located within the receiving space M, and a dimension smaller in the horizontal direction than the width of the portion of the chain belt 02 located within the receiving space M. Based on this, it can be ensured that during the movement of the zipper head 01 along the chain belt 02, the portion of the chain belt 02 located within the receiving space M will not detach from the zipper head 01 through the gap N, and there will be no jamming between the chain belt 02 and the zipper head 01, ensuring normal connection between the zipper head 01 and the chain belt 02 and smooth movement of the zipper head 01 on the chain belt 02.

[0022] It should be noted that the portion of the chain 02 located within the accommodating space M may include chain teeth 021 and a local area of ​​the fabric tape 022 for mounting chain teeth 021.

[0023] Furthermore, the chain 02 can be a flat, elongated strip. The gap N in the left-right direction is smaller than the width of the portion of the chain 02 located within the receiving space M (e.g., chain teeth 021), effectively preventing the portion of the chain 02 within the receiving space M from moving out of the receiving space M vertically via the gap N. Similarly, the gap N in the vertical direction is smaller than the thickness of the portion of the chain 02 within the receiving space M, effectively preventing the portion of the chain 02 within the receiving space M from moving out of the receiving space M horizontally via the gap N. Therefore, a reliable connection between the slider 01 and the chain 02 is ensured, and the slider 01 can move smoothly along the chain 02.

[0024] In this embodiment, the engagement area of ​​the chain tooth 021 is located in the middle of the pull head 01, and the dimensions of the gap N in the vertical and horizontal directions are smaller than the thickness and width dimensions of the chain belt 02, respectively. According to the basic knowledge of solid geometry, three points that are not on the same straight line can determine a plane, and three points are sufficient to allow the chain tooth 021 to move smoothly within the accommodating space M, so as to achieve smooth engagement or disengagement of the chain tooth 021.

[0025] In some embodiments, the distance between the front end region of the projection of the left edge of the upper plate structure 10 onto the base plate 21 and the front end region of the left plate 22 can be greater near the front end region than near the rear end region, and the maximum distance needs to be less than the width of the portion of the chain belt 02 located within the receiving space M. Based on this, on the one hand, it can adapt to the extension direction of the chain belt 02, promoting the smooth movement of the zipper head 01 along the chain belt 02; on the other hand, it can effectively prevent the portion of the chain belt 02 located within the receiving space M (e.g., chain teeth 021) from detaching from the receiving space M between the left edge of the upper plate structure 10 and the left plate 22, thereby ensuring a stable connection between the chain belt 02 and the zipper head 01, preventing the chain belt 02 from detaching from the zipper head 01. Furthermore, the fabric 022 of the chain belt 02 can extend from the left edge of the upper plate structure 10 and the left plate 22 out of the receiving space M to ensure that the zipper head 01 can move smoothly along the chain belt 02.

[0026] Similarly, the distance between the front end region of the projection of the right edge of the upper plate structure 10 onto the base plate 21 and the front end region of the right side plate 23 can be greater near the front end than near the rear end, and the maximum distance is less than the width of the portion of the chain belt 02 located within the receiving space M. Based on this, on the one hand, it can adapt to the extension direction of the chain belt 02, promoting the smooth movement of the zipper head 01 along the chain belt 02; on the other hand, it can effectively prevent the portion of the chain belt 02 located within the receiving space M (e.g., chain teeth 021) from detaching from the receiving space M between the right edge of the upper plate structure 10 and the right side plate 23, thereby ensuring a stable connection between the chain belt 02 and the zipper head 01, preventing the chain belt 02 from detaching from the zipper head 01. Furthermore, it can also allow the fabric 022 of the chain belt 02 to extend from the right edge of the upper plate structure 10 and the right side plate 23 out of the receiving space M, ensuring that the zipper head 01 can move smoothly along the chain belt 02. In some more specific embodiments, the distance between the front end region of the projection of the left edge of the upper plate structure 10 onto the base plate 21 and the front end region of the left plate 22, and the distance between the front end region of the projection of the right edge of the upper plate structure 10 onto the base plate 21 and the front end region of the right plate 23, can be gradually reduced from front to back.

[0027] In some embodiments, the left side plate 22 and the right side plate 23 may each have an edge 24 at one end away from the bottom plate 21, and the edge 24 protrudes into the receiving space M. Based on this arrangement, the edge 24 can play a certain limiting role in the chain tooth 021 located in the receiving space M, so as to prevent the chain tooth 021 from leaving the receiving space M; in addition, there may be a gap N between the edge 24 and the upper plate structure 10, so that the fabric 022 of the chain belt 02 can pass through the receiving space M between the edge 24 and the upper plate structure 10.

[0028] Optionally, the connection between the edge 24 and the left side plate 22 or the right side plate 23 can be an arc-shaped structure. On the one hand, it can adapt to the contour of the chain tooth 021, which can increase the contact area with the chain tooth 021 and improve the stability of the chain tooth 021 in the accommodating space M. On the other hand, it can also alleviate the problem of stress concentration at the connection between the edge 24 and the left side plate 22 or the right side plate 23, which is conducive to improving the strength of the lower plate structure 20, thereby increasing the service life of the slider 01.

[0029] In addition, the edge 24 may be provided with an inclined guide surface at the end away from the left side plate 22 or the right side plate 23 and in the area facing the upper plate structure 10. The inclined guide surface can support the cloth tape 022 of the chain belt 02 and play a certain role in avoiding obstruction, so as to ensure that the cloth tape 022 can be smoothly passed between the edge 24 and the upper plate structure 10, so as to prevent the cloth tape 022 from being stuck between the edge 24 and the upper plate structure 10, and ensure the smooth movement of the pull head 01.

[0030] In some embodiments, the width of the front end region of the upper plate structure 10 in the left-right direction can be greater than the width of the rear end region of the upper plate structure 10 in the left-right direction. This allows the front end region of the upper plate structure 10 to have a larger area, thereby ensuring the reliability and stability of the connection between the connecting post 30 and the upper plate structure 10. Simultaneously, the front end region of the upper plate structure 10 can also shield the connecting post 30, which can improve the appearance of the slider 01 to some extent.

[0031] The width of the rear end region of the upper plate structure 10 in the left-right direction is smaller than that of the front end region. Thus, compared with the upper plate structure 10 with equal front and rear dimensions, the projected area of ​​the upper plate structure 10 in the vertical direction in this embodiment is smaller, which is conducive to the miniaturization and lightweighting of the entire zipper pull 01, and can save materials and reduce costs. In addition, it can also reduce the contact area between the upper plate structure 10 and the chain 02, thereby reducing the resistance of the chain 02 to the zipper pull 01, and enabling the zipper pull 01 to move more smoothly.

[0032] In some more specific embodiments, the width of the upper plate structure 10 in the left-right direction can be increased and then decreased from front to back. This can reduce the area of ​​the upper plate structure 10, make the overall outline of the upper plate structure 10 more rounded, prevent the upper plate structure 10 from scratching the user's fingers, and also improve the appearance.

[0033] In some more specific embodiments, the upper plate structure 10 may include a disc-shaped plate 11 and a long strip plate 12, wherein the disc-shaped plate 11 is located in the front end region, and the long strip plate 12 is located in the rear end region and connected to the disc-shaped plate 11, and the width of the long strip plate 12 in the left-right direction may be smaller than the width of the disc-shaped plate 11. Based on this, the area of ​​the front end region of the upper plate structure 10 can be larger than the area of ​​the rear end region, so as to increase the connection area between the connecting post 30 and the upper plate structure 10. Optionally, the connecting post 30 may be connected to the disc-shaped plate 11.

[0034] For example, the disc-shaped plate 11 can be a circular plate, a polygonal plate, an elliptical plate, etc., and the strip plate 12 can be a long rectangular plate, etc. Of course, it can also be other shapes, which are not specifically limited here.

[0035] In some embodiments, the slider 01 can be a self-locking slider. The side of the upper plate structure 10 opposite to the lower plate structure 20 may be provided with a self-locking structure. After the slider 01 moves to a designated position, the self-locking structure can lock the slider 01 to the chain teeth 021, thereby effectively preventing the slider 01 from moving arbitrarily. It should be noted that the specific structure and working principle of the self-locking structure can refer to existing technologies and are not specifically limited here.

[0036] In some other embodiments, the zipper pull 01 can also be a non-locking zipper pull. In this case, the side of the upper plate structure 10 that is away from the lower plate structure 20 does not have a self-locking structure.

[0037] Based on the aforementioned zipper pull 01, this application embodiment also discloses an article having chain teeth 021. The disclosed article includes a pair of chain straps 02 and the aforementioned zipper pull 01.

[0038] Among them, a pair of chain belts 02 have multiple chain teeth 021 discharged. The gap N in the vertical direction is smaller than the thickness of the part of the chain belt 02 located in the receiving space M, and the gap N in the horizontal direction is smaller than the width of the part of the chain belt 02 located in the receiving space M. The pull head 01 is movably disposed on a pair of chain belts 02 so that the chain teeth 021 of the pair of chain belts 02 can engage or disengage.

[0039] Based on the above settings, the portion of the chain 02 located within the receiving space M can be effectively prevented from moving out of the receiving space M through the gap N, ensuring a stable connection between the pull head 01 and the chain 02. At the same time, the pull head 01 can also move smoothly along the chain 02.

[0040] Optionally, the item can be clothing, a flexible bag, or a zipper; of course, the item can also be in other forms, without specific limitations.

[0041] Optionally, the chain tooth 021 can be a plastic chain tooth, a nylon chain tooth, or a metal chain tooth. It should be noted that the shapes of the upper plate structure 10 and the lower plate structure 20 of the zipper pull 01 can be adapted to plastic chain teeth, nylon chain teeth, or metal chain teeth to ensure that the zipper pull 01 can move smoothly along the chain belt 02 without being obstructed by the chain tooth 021.

[0042] When the chain tooth 021 is a nylon chain tooth, the thickness of the chain belt 02 is the sum of the thickness of the chain tooth 021 and the thickness of the fabric belt 022; when the chain tooth 021 is an injection molded chain tooth, such as a plastic chain tooth or a metal chain tooth, the thickness of the chain belt 02 is the same as the thickness of the chain tooth 021.

[0043] In some embodiments, the upper plate structure 10 may be provided with a hook 40 on the side opposite to the lower plate structure 20. One end of the hook 40 is connected to the upper plate structure 10, and the other end of the hook 40 is relatively separable from the upper plate structure 10, so as to facilitate the installation of the pull tab to the hook 40.

[0044] Optionally, the front end of the hook 40 is fixed to the position of the upper plate structure 10 corresponding to the connecting column 30 to improve the installation stability of the hook 40 and ensure that the hook 40 is not easily deformed by the upper plate structure 10 when subjected to tension, thereby ensuring the overall strength and rigidity of the pull head 01.

[0045] 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.
