Description

Technical Field

[0001] This utility model belongs to the technical field of shoemaking auxiliary tooling equipment, specifically relating to an auxiliary device for attaching and bending zippers in shoes. Background Technology

[0002] Shoe designs and structures are evolving towards greater comfort, lightness, and environmental friendliness. In recent years, with technological advancements and rising consumer demands, footwear brands have begun to focus on the overall fit, breathability, aesthetics, and convenience of shoes to provide a better wearing experience. For example, some specialized footwear, while maintaining appearance and functionality, also requires quick and easy on and off. Zippers are standard in shoe upper designs that enable quick and easy on and off. Curved zippers on shoe uppers not only improve shoe performance but also increase product appeal, meeting modern consumers' demands for personalized and high-tech products. Different styles of shoes and boots have significantly different zipper curvatures. Currently, most zippers produced in my country are straight zippers. Producing shoes and boots with zippers of varying curvatures using straight zippers, and ensuring consistent zipper curvature during installation, presents a significant challenge for upper production.

[0003] Chinese patent application number 202022813842.2 discloses a bending and shaping device for boot zippers. The device places the zipper within a groove with a certain curvature on a partition. A servo motor drives the partition, causing the zipper to pass sequentially through a heating structure and a cooling structure. The heating structure presses the zipper, while the cooling structure freezes it, thus achieving bending and shaping. However, different zipper models require different groove shapes, necessitating the replacement of different partitions. Furthermore, the curvature of the grooves on the partitions is fixed and cannot be adjusted. To accommodate zippers with varying degrees of curvature, different partitions are required. Summary of the Invention

[0004] In view of the above-mentioned problems in the existing technology, this utility model provides an auxiliary device for gluing and bending zippers on shoes with a simple structure and adjustable bending curvature.

[0005] The purpose of this utility model is achieved in the following way: an auxiliary device for gluing and bending zippers on shoes, characterized in that: it includes an upper fixing plate, on which an elastic zipper slot and a zipper bending arc adjustment mechanism are provided. The zipper bending arc adjustment mechanism includes a control rod, a control groove, a control handle, and a stop rod. One end of the zipper slot is engaged with the end of the upper fixing plate, and the other end is hinged to the control rod. The other end of the control rod is fixedly connected to the control handle. A control groove is provided below the control rod, and at least two stop rods are provided in the control groove. When the zipper is placed in the zipper slot, the control handle is pushed and the stop rods are used to limit and fix it, thereby changing the bending arc of the zipper slot and the zipper.

[0006] The zipper slot is made of high-elastic steel sheet.

[0007] Three stop levers are installed inside the control slot.

[0008] The side panel fixing plate is equipped with a retractable left stop and / or right stop.

[0009] The side panel fixing plate is fan-shaped, with one end larger than the other.

[0010] Compared to existing technologies, this invention utilizes the elastic deformation characteristics of zipper slots. By deforming the zipper slots, the zipper is driven to deform according to the designed curvature. The deformed zipper is directly fixed to the upper of the shoe or boot, eliminating the need for a zipper shaping mechanism that requires both heat treatment and freezing. This invention ensures that the curvature of the zipper after being glued and fixed is consistent with the designed curvature, and the structure is simpler. Adjusting the curvature of the zipper's bending deformation is more convenient, and the ease of use is also improved. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading the contents of the present invention, those skilled in the art can make various modifications or alterations to the present invention, and these equivalent forms also fall within the scope defined by the present invention.

[0019] like Figure 1-2As shown, an auxiliary device for bending zippers on footwear includes an upper fixing plate 1, on which an elastic zipper slot 2 and a zipper bending curvature adjustment mechanism are provided. The zipper slot 2 is preferably a cuboid without an upper surface and a lower surface, formed by bending a high-elastic steel sheet that is 1-2mm thick and 5-6mm wide. The zipper bending curvature adjustment mechanism includes a control rod 3, a control groove 4, a control handle 5, and a stop rod 6. One end of the zipper slot 2 is engaged with the end of the upper fixing plate 1, and the other end is hinged to the control rod 3. The other end of the control rod 3 is fixedly connected to the control handle 5. The control groove 4 is provided below the control rod 3, and at least two stop rods 6 are provided in the control groove 4. The zipper teeth and the zipper pull are placed in the zipper slot 2. When the control handle 5 is pushed, the zipper slot 2 is squeezed and undergoes elastic deformation, thereby changing the bending curvature of the zipper. The stop rods 6 limit the position of the control handle 5, thereby fixing the zipper slot 2 and the bending curvature of the zipper.

[0020] When the control handle 5 is pushed and the zipper slot 2 is squeezed and undergoes elastic deformation, if the two sides of the zipper slot 2 deform in two different directions, one side of the zipper slot 2 can be moved by hand to make it bend and deform along the designed arc. The position of the control handle 5 is limited by the stop lever 6, and the bending arc of the zipper slot 2 and the zipper is fixed. Since the zipper slot 2 is made of thin high-elastic steel sheet, it will only deform along the length of the zipper and will not bulge upward or undergo other random deformations.

[0021] Furthermore, a retractable left stop and / or right stop can be provided on the upper fixing plate 1 to ensure that the zipper slot 2 can only bend in the designed direction during initial deformation. If the zipper slot 2 needs to bend to the right, the left stop is raised to prevent the zipper slot 2 from bending to the left; if the zipper slot 2 needs to bend to the left, the right stop is raised to prevent the zipper slot 2 from bending to the right. An upper fixing plate 1 and the zipper slot 2 and zipper bending arc adjustment mechanism above it can be used to fix the curved zipper on a single shoe upper. In this case, a retractable left or right stop is provided on the upper fixing plate 1. Alternatively, it can be used to fix the curved zippers on two shoe uppers, in which case a retractable left and right stop are provided on the upper fixing plate 1. The telescopic structure of the left and right stops is similar to the press-and-release structure of a ballpoint pen.

[0022] The control slot 4 is equipped with three or more stop levers 6 to accommodate different curvatures of curvature. See Figures 4-6 .

[0023] Furthermore, such as Figure 7As shown, the upper fixing plate 1 is fixedly mounted on the bearing seat 7, and the bearing seat 7 is connected to the fixed base 9 via the shaft 8. The shaft 8 and the fixed base 9 are rotatably connected. At least two upper fixing plates 1 are evenly arranged along the circumference of the bearing seat 7. The upper fixing plate 1, the elastic zipper slot 2, and the zipper bending arc adjustment mechanism are designed to rotate along the fixed base for easier operation. The upper fixing plate 1 can also be fixed by hanging from above.

[0024] The upper fixing plate 1 is a fan shape with one end larger than the other. Since the boot shaft is smaller at the end near the ankle and larger at the end near the leg, the upper fixing plate 1 is designed as a fan shape with one end larger than the other to adapt to the shape of the boot shaft and make it easier to fix the zipper to the upper of the shoe.

[0025] In use, the control handle 5 is positioned outside the outermost stop lever 6 within the control groove 4, ensuring the zipper slot 2 is in a straight line. Then, the engagement point between the zipper slot 2 and the end of the upper fixing plate 1 is lifted. Figure 3 Place the zipper on the upper fixing plate 1, lower the zipper slot 2, and secure the zipper slot 2 to the end of the upper fixing plate 1. Adjust the zipper position so that the zipper pull and teeth are in the zipper slot 2. Push the control handle 5 towards the smaller end of the upper fixing plate 1 to compress the zipper slot 2, causing it to bend and deform, which in turn causes the zipper inside the slot 2 to bend and deform as well. After the zipper's curvature is fixed, wrap the shoe upper over the upper fixing plate 1, and glue or sew the two zipper straps to the two sides of the shoe upper.

[0026] This invention utilizes the elastic deformation characteristics of zipper slots to deform the zipper according to the designed curvature. The deformed zipper is then directly fixed to the upper of the shoe or boot, eliminating the need for a zipper shaping mechanism that requires both heat treatment and freezing. This invention ensures that the curvature of the zipper after gluing and fixing is consistent with the designed curvature, and the structure is simpler. Adjusting the curvature of the zipper during bending and deformation is more convenient, and the ease of use is also improved.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
