Description

Technical Field

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

[0002] In some zipper applications of related technologies, the ends of the zipper are fixed with fabric, thus limiting the zipper's position. As the zipper pull slides along the zipper, when it reaches the end, the front end of the pull will press against the fabric and cannot be pulled further forward. This prevents the ends of a pair of zippers from joining together, creating a gap. Furthermore, the zipper pull cannot conceal the gap, leaving it exposed and affecting the overall appearance of items with zippers. Utility Model Content

[0003] The purpose of this application is to provide a zipper pull and an article with a zipper that can solve problems such as the gap at the ends of a pair of zipper teeth due to obstructed movement of the zipper pull, which affects the appearance.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides a zipper puller, including: an upper wing plate, a lower wing plate, and a connecting post;

[0006] The upper wing plate and the lower wing plate are spaced apart in the vertical direction, and the front end of the upper wing plate protrudes beyond the front end of the lower wing plate;

[0007] The connecting post is located between the upper wing plate and the lower wing plate, with one end of the connecting post fixed to the middle area of ​​the upper wing plate and the other end of the connecting post fixed to the front end of the lower wing plate.

[0008] The front end of the lower wing plate protrudes outward from the edges of the left and right sides of the connecting column.

[0009] This application embodiment also provides an article with a zipper, including: fabric and a zipper disposed on the edge of the fabric;

[0010] The zipper includes a pair of chain straps, a zipper pull, and a zipper tab. The zipper pull is slidably disposed on the pair of chain straps and engages or disengages the pair of chain straps during sliding. The zipper tab is mounted on the zipper pull.

[0011] In this embodiment, the upper and lower wing plates are spaced apart, and a connecting post connects the upper and lower wing plates, forming a space for accommodating the zipper teeth and ensuring stability between the upper and lower wing plates. Furthermore, the front end of the upper wing plate protrudes beyond the front end of the lower wing plate and the connecting post, creating a certain clearance space between the front end of the upper wing plate, the front end of the lower wing plate, and the connecting post. Thus, when the zipper pull is pulled along the zipper teeth, the connecting post gradually approaches the fabric. When the connecting post contacts the fabric, the protruding area of ​​the front end of the upper wing plate protrudes into the fabric, allowing the protruding area of ​​the upper wing plate to cover the ends of a pair of zipper teeth and a portion of the fabric. This covers the gap at the ends of a pair of zipper teeth and the connection between the zipper teeth and the fabric, preventing the gap and the connection between the zipper teeth and the fabric from being exposed, thus ensuring the overall appearance of the zippered item.

[0029] 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.

[0030] 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.

[0031] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0032] refer to Figures 1 to 9 This application discloses a zipper pull 01 for slidingly engaging with chain teeth on a pair of chain belts 03, so as to achieve the engagement or disengagement of the pair of chain teeth by sliding the zipper pull 01 on the pair of chain belts 03. The disclosed zipper pull 01 includes an upper wing plate 10, a lower wing plate 20, and a connecting post 30.

[0033] The upper wing plate 10 and the lower wing plate 20 are spaced apart in the vertical direction, and the connecting post 30 is located between the upper wing plate 10 and the lower wing plate 20. In this way, the upper wing plate 10 and the lower wing plate 20 can be fixed together by the connecting post 30 to ensure the stability between the upper wing plate 10 and the lower wing plate 20; and the chain teeth can pass through the upper wing plate 10, the lower wing plate 20 and the connecting post 30.

[0034] Optionally, one end of the connecting column 30 can be fixed to the upper wing plate 10, and the other end of the connecting column 30 can be fixed to the lower wing plate 20, so as to support and fix the upper wing plate 10 and the lower wing plate 20 respectively through the connecting column 30.

[0035] Furthermore, the front end of the upper wing plate 10 protrudes beyond the front end of the lower wing plate 20, and one end of the connecting post 30 is fixed to the middle region of the upper wing plate 10, while the other end of the connecting post 30 is fixed to the front end of the lower wing plate 20. The front end of the lower wing plate 20 protrudes outward from the edges of the regions on the left and right sides of the connecting post 30. In this way, a certain space can be formed between the protruding area of ​​the upper wing plate 10, the connecting post 30, and the lower wing plate 20 to facilitate a space-avoidance function.

[0036] Based on the above configuration, in this embodiment, the upper wing plate 10 and the lower wing plate 20 are spaced apart, and the connecting post 30 is connected between the upper wing plate 10 and the lower wing plate 20, so that a receiving space for accommodating the chain teeth can be formed between the upper wing plate 10, the lower wing plate 20 and the connecting post 30, and the stability between the upper wing plate 10 and the lower wing plate 20 is ensured; furthermore, the front end of the upper wing plate 10 protrudes beyond the front end of the lower wing plate 20 and the connecting post 30, so that a certain clearance space is formed between the front end of the upper wing plate 10, the front end of the lower wing plate 20 and the connecting post 30. Thus, when the zipper 01 is pulled along the chain teeth, the connecting post 30 gradually approaches the fabric 04. When the connecting post 30 contacts the fabric 04, the protruding area at the front end of the upper wing plate 10 protrudes into the fabric 04, so that the protruding area of ​​the upper wing plate 10 can cover the ends of a pair of chain teeth and a part of the fabric 04. This can cover the gap at the ends of a pair of chain teeth and the connection between the chain teeth and the fabric 04, preventing the gap and the connection between the chain teeth and the fabric 04 from being exposed, thus ensuring the overall appearance of the zippered item.

[0037] refer to Figure 9 In some embodiments, the maximum width of the area of ​​the upper wing plate 10 protruding from the lower wing plate 20 in the left-right direction is less than or equal to the maximum width of the lower wing plate 20 in the left-right direction. This can help reduce the width of the area of ​​the upper wing plate 10 protruding from the lower wing plate 20, thereby reducing the area of ​​this region. This can alleviate the problem of the upper wing plate 10 being too wide and occupying too much space, and also help improve the appearance of the zipper pull 01, further improving the appearance of items with zippers.

[0038] Furthermore, in the region of the protrusion of the upper wing plate 10 and the lower wing plate 20, the width dimension in the left-right direction near the front end of the lower wing plate 20 is greater than the width dimension in the left-right direction away from the front end of the lower wing plate 20. That is, the width dimension in the left-right direction of the rear end of the protrusion region is greater than the width dimension in the left-right direction of the front end of the protrusion region. This can help reduce the space occupied by the front end region of the upper wing plate 10 (i.e., the front end of the protrusion region) in the left-right direction. On the one hand, it reduces the space occupied by the front end region of the upper wing plate 10, and on the other hand, it can make the upper wing plate 10 appear to be narrower in the front and wider in the back, thereby improving its appearance.

[0039] Furthermore, from rear to front, the width of the area of ​​the upper wing 10 protruding from the lower wing 20 gradually decreases in the left-right direction. Based on this arrangement, not only does the space occupied by the protruding area gradually decrease from rear to front, but the protruding area of ​​the upper wing 10 also looks more symmetrical, further improving the appearance of the upper wing 10.

[0040] In some embodiments, the area of ​​the upper wing plate 10 that protrudes from the lower wing plate 20 may have an arc-shaped profile or a rounded rectangular profile. Based on this, the outer contour of the protruding area can be made more rounded and full. On the one hand, this can avoid the situation where the outer contour of the protruding area has sharp edges that could scratch the user or the fabric 04. On the other hand, it can also improve the appearance of the upper wing plate 10.

[0041] Optionally, the outer contour of the protruding area can be a circular arc contour, a non-circular arc contour, etc.

[0042] like Figure 9 As shown in Figure a, in this type of upper wing plate 10, the width dimension of the rear end of the protruding region along the left-right direction is equal to the width dimension of the lower wing plate 20 at that location, and the width dimension of the protruding region gradually decreases from the rear end of the protruding region forward; and the outline of the protruding region protrudes beyond the entire outline of the front side of the lower wing plate 20. In addition, the front end of the protruding region has an arc-shaped outline.

[0043] like Figure 9 As shown in b, in this type of upper wing plate 10, the width dimension of the rear end of the protruding region in the left-right direction is smaller than the width dimension of the lower wing plate 20 at that location. Furthermore, the width dimension of the protruding region initially remains constant from the rear end forward, then gradually decreases. The outline of the protruding region protrudes beyond the outline of a local area on the front side of the lower wing plate 20. Additionally, the front end of the protruding region has a rounded rectangular outline.

[0044] like Figure 9As shown in Figure c, in this type of upper wing plate 10, the width dimension of the rear end of the protruding region along the left-right direction is equal to the width dimension of the lower wing plate 20 at that location. Furthermore, from the rear end of the protruding region forward, the width dimension of the protruding region initially remains constant and then gradually decreases; and the outline of the protruding region protrudes beyond the entire outline of the front side of the lower wing plate 20. Additionally, the front end of the protruding region has a rounded rectangular outline.

[0045] like Figure 9 As shown in d, in this type of upper wing plate 10, the width dimension of the rear end of the protruding region along the left-right direction is equal to the width dimension of the lower wing plate 20 at that location. Furthermore, the width dimension of the protruding region initially remains constant from the rear end forward, then gradually decreases; and the outline of the protruding region protrudes beyond the entire outline of the front side of the lower wing plate 20. Additionally, the front end of the protruding region has an arc-shaped outline.

[0046] like Figure 9 As shown in Figure e, in this type of upper wing plate 10, the width dimension of the rear end of the protruding region in the left-right direction is smaller than the width dimension of the lower wing plate 20 at that location, and the width dimension of the protruding region gradually decreases from the rear end of the protruding region forward; and the outline of the protruding region protrudes beyond the outline of a local area on the front side of the lower wing plate 20. In addition, the front end of the protruding region has an arc-shaped outline.

[0047] Of course, it is not limited to the above methods. The outline of the protruding area can also be in other ways, which are not specifically limited here.

[0048] refer to Figure 8 In some embodiments, the side of the lower wing plate 20 facing the upper wing plate 10 may be provided with a first guide groove 21 and a second guide groove 22, and the first guide groove 21 and the second guide groove 22 respectively pass through the pull head 01 in the front-rear direction and are located on the left and right sides of the connecting column 30 respectively.

[0049] Based on the above configuration, one of the pair of chain teeth can be accommodated by the first guide groove 21, which also guides the chain tooth to prevent it from moving arbitrarily; the other of the pair of chain teeth can be accommodated by the second guide groove 22, which also guides the chain tooth to prevent it from moving arbitrarily. Therefore, the cooperation of the first guide groove 21 and the second guide groove 22 ensures smooth and stable movement of the pair of chain teeth, thus facilitating the stable engagement or disengagement of the pair of chain teeth.

[0050] Optionally, such as Figure 8As shown, the lower wing plate 20 may include a lower base plate 20a, a left side plate 20b, and a right side plate 20c. The left side plate 20b and the right side plate 20c are respectively located at the left and right ends of the lower base plate 20a facing the surface of the upper wing plate 10, and extend toward the upper wing plate 10, so that the lower base plate 20a, the left side plate 20b, and the right side plate 20c can together form a concave space.

[0051] Furthermore, the surface of the lower base plate 20a facing the upper wing plate 10 may also be provided with a protruding strip, which extends in the front-rear direction and is located in the middle region of the lower base plate 20a in the left-right direction. In this way, a first guide groove 21 can be formed between the protruding strip, the left side plate 20b and the lower base plate 20a, and a second guide groove 22 can be formed between the protruding strip, the right side plate 20c and the lower base plate 20a.

[0052] In addition, the surface of the left side plate 20b facing the right side plate 20c may also be provided with a first recess to provide a larger accommodating space for the first guide groove 21; correspondingly, the surface of the right side plate 20c facing the left side plate 20b may also be provided with a second recess to provide a larger accommodating space for the second guide groove 22.

[0053] refer to Figure 4 and Figure 5 In some embodiments, the left and right edges of the surface of the upper wing plate 10 facing the lower wing plate 20 may be provided with a left convex edge and a right convex edge, respectively. The left convex edge is opposite to and spaced apart from the left side plate 20b, and the right convex edge is opposite to and spaced apart from the right side plate 20c. Based on this, the left convex edge and the left side plate 20b can work together to limit one of the pair of chain teeth, preventing the chain tooth from disengaging from the first guide groove 21, and also providing space for one side edge of the fabric 04 to pass through; the right convex edge and the left side plate 20b can work together to limit the other of the pair of chain teeth, preventing the chain tooth from disengaging from the second guide groove 22, and also providing space for the other side edge of the fabric 04 to pass through.

[0054] refer to Figure 6 In some embodiments, a first reinforcing rib 41 may be provided at the connection between the upper wing plate 10 and the connecting post 30. The first reinforcing rib 41 is located in the rear region of the connecting post 30. Based on the provision of the first reinforcing rib 41, the bonding strength between the connecting post 30 and the upper wing plate 10 can be greatly improved, preventing cracking or even breakage at the connection between the upper wing plate 10 and the connecting post 30 when the slider 01 is pulled with a large pulling force, which is beneficial to extending the service life of the slider 01.

[0055] Optionally, the first reinforcing rib 41 can be a triangular reinforcing rib. Since triangles have strong stability, they can further improve the strength of the connection between the connecting column 30 and the upper flange 10.

[0056] In addition, the first reinforcing rib 41 is also hidden in the internal space of the slider 01, which can help improve the appearance of the slider 01.

[0057] In some embodiments, a second reinforcing rib 42 may be provided at the connection between the lower flange 20 and the connecting post 30. The second reinforcing rib 42 is located in the rear region of the connecting post 30. Based on the provision of the second reinforcing rib 42, the bonding strength between the connecting post 30 and the lower flange 20 can be greatly improved, preventing cracking or even breakage at the connection between the lower flange 20 and the connecting post 30 when the slider 01 is pulled with a large pulling force, thus helping to extend the service life of the slider 01.

[0058] Optionally, the second reinforcing rib 42 can be a triangular reinforcing rib. Since triangles have strong stability, they can further improve the strength of the connection between the connecting column 30 and the lower flange 20.

[0059] In addition, the second reinforcing rib 42 is also hidden in the internal space of the slider 01, which can help improve the appearance of the slider 01.

[0060] refer to Figures 4 to 6 In some embodiments, the zipper pull 01 may further include a hook 50, one end of which is fixed to the front area of ​​the upper wing plate 10 facing away from the lower wing plate 20. At least part of one end of the hook 50 protrudes from the connecting post 30 in the front-rear direction. It should be noted that because the front end of the upper wing plate 10 protrudes from the front end of the lower wing plate 20, the protruding area of ​​the upper wing plate 10 has a large empty space facing away from the lower wing plate 20, affecting the appearance of the zipper pull 01. However, since at least part of one end of the hook 50 protrudes from the connecting post 30 in the front-rear direction, at least part of one end of the hook 50 can be located in this empty space, thereby covering and occupying the protruding area of ​​the upper wing plate 10 on the surface facing away from the lower wing plate 20. This improves the overall coordination of the zipper pull 01 and enhances its overall appearance.

[0061] In addition, along the vertical direction, one end of the hook 50 can also have an overlapping area with the connecting post 30. In this way, the connecting post 30 can strengthen the corresponding area of ​​the upper wing plate 10. After the hook 50 is installed, the load-bearing capacity of the hook 50 can be improved so that the hook 50 will not cause the upper wing plate 10 to deform or even break when subjected to tension.

[0062] The other end of the hook 50 extends to the rear region of the upper wing plate 10 and forms a bayonet with the surface opposite to the lower wing plate 20, so as to facilitate the installation of the pull tab 02 to the hook 50.

[0063] Optionally, the hook 50 may have a certain degree of elasticity so that it can undergo elastic deformation when the pull tab 02 is installed, so that the locking hole of the pull tab 02 can be engaged with the hook 50.

[0064] In some embodiments, the zipper head 01 can be an integral structure; of course, the upper wing plate 10 and the lower wing plate 20 can be fixedly connected to the connecting post 30, and the hook 50 can be fixedly connected to the upper wing plate 10, such as by welding, bonding, etc.

[0065] In some embodiments, the surface of the upper wing plate 10 facing the lower wing plate 20 and located at the front end may be provided with a first transition surface. The first transition surface may be an inclined plane or an inclined arc surface, so that the front end of the upper wing plate 10 appears more rounded and is less likely to scratch the fabric 04.

[0066] Similarly, the surface of the lower wing plate 20 facing the upper wing plate 10 and located at the front end can be provided with a second transition surface. This second transition surface can be an inclined plane or an inclined arc surface, making the front end of the lower wing plate 20 appear more rounded and less likely to scratch the fabric 04.

[0067] Based on the aforementioned zipper head 01, this application embodiment also discloses an item with a zipper, see reference. Figures 1 to 3 The disclosed article includes fabric 04 and a zipper located at the edge of fabric 04. The zipper may include a pair of chain straps 03, the aforementioned zipper head 01 and pull tab 02. The zipper head 01 is slidably disposed on the pair of chain straps 03 and engages or disengages the pair of chain straps 03 during sliding. The pull tab 02 is mounted on the zipper head 01.

[0068] Based on the above settings, the user can apply force to the pull tab 02 to drive the pull head 01 to slide along a pair of chain belts 03, thereby achieving the engagement or disengagement of the pair of chain belts 03.

[0069] Optionally, the chain strap 03 can be sewn to the edge of the fabric 04 with stitch 05 to ensure the strength and reliability of the connection between the chain strap 03 and the fabric 04.

[0070] For example, the item with the zipper can be clothing, a flexible bag, etc., and of course, it can also be other items that use the zipper described above, without being specifically limited here. Among them, when the item with the zipper is clothing, the protruding area of ​​the upper wing plate 10 can cover the gap, which can also effectively alleviate the problem of external wind entering the clothing through the gap and affecting the user's wearing experience.

[0071] 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.
