Description

Technical Field

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

[0002] The core function of a zipper is to quickly, reliably, and repeatedly open and close two pieces of flexible material (usually fabric), thus replacing traditional closure methods such as buttons and ties. Its necessity is reflected in four dimensions: efficiency, reliability, sealing, and aesthetics. It is an irreplaceable "invisible infrastructure" in modern clothing, equipment, and industrial products.

[0003] With the diversification of zipper shapes today, we continue to explore and refine their aesthetics and functionality. For existing zippers, a portion of the coated surface is removed through subtractive manufacturing to obtain a flat surface formed by the resin matrix. This flat surface needs to bear the function of contacting the base plate during the zipper teeth engagement process. Therefore, due to the rigid requirements of structural strength, the surface shape design is relatively limited and the aesthetics are poor.

[0004] In conclusion, improving the aesthetics of zippers 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 tooth with a recessed portion that partially covers the planar section and the inclined section, so that the zipper tooth has different visual effects and tactile feel, thereby improving the aesthetics of the zipper.

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

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

[0008] A tooth, comprising:

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.

[0037] The core of this utility model is to provide a tooth, the recessed part on the surface of which can improve the design and aesthetics of the zipper.

[0038] Another core aspect of this invention is providing a zipper that includes the aforementioned teeth.

[0039] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description. It 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, and therefore should not be construed as a limitation of this application.

[0040] The present application provides a tooth comprising: an engaging base 1, a non-engaging portion 2, and a recessed portion 3;

[0041] Among them, the meshing base 1 serves as the base of the tooth;

[0042] The non-engaging part 2 is fixedly connected to the engaging base 1. The side surface of the non-engaging part 2 away from the engaging base 1 includes a planar section 201 and an inclined section 202. A recessed part 3 is provided at the connection between the planar section 201 and the inclined section 202. The bottom surface of the recessed part 3 is closer to the engaging base 1 than the planar section 201.

[0043] For details, please refer to the appendix. Figure 1 The meshing base 1 is the base of the teeth, and the non-meshing part 2 is located above the meshing base 1 and fixedly connected to the meshing base 1. A groove is provided between the meshing base 1 and the non-meshing part 2. This groove is used to connect the textile tape part of the zipper. The upper surface of the non-meshing part 2 consists of two parts, namely the flat section 201 and the inclined section 202. The area of ​​the flat section 201 is generally flat, and the inclined section 202 has a downward inclined tendency. When the recessed part 3 is not provided, the connection between the flat section 201 and the inclined section 202 is smoothly transitioned. At the connection between the flat section 201 and the inclined section 202, a recessed part 3 is provided that extends along the width direction of the non-meshing part 2. The recessed part 3 partially covers the flat section 201 and the inclined section 202, and the bottom height of the recessed part 3 does not exceed the surface of the flat section 201 and the inclined section 202. Compared with the material reduction directly in the flat section 201, this scheme reduces the cutting resistance and has a clear entry point. From an aesthetic point of view, it can achieve a natural connection and transition between the flat section 201 and the inclined section 202, making the surface of the non-engaging part 2 after setting the recessed part 3 more complex than the structure of ordinary teeth, so that the surface of the non-engaging part 2 can obtain different visual effects and tactile feel. After the above-mentioned multiple teeth are combined into a zipper, the overall design and aesthetics of the zipper are greatly improved.

[0044] Based on the above embodiment, the included angle between the planar segment 201 and the inclined segment 202 is an obtuse angle, and the bottom surface of the recessed portion 3 is a plane.

[0045] For details, please refer to the appendix. Figure 1 With appendix Figure 2The schematic diagram of the first type of tooth structure provided in this application shows that the upper surface of the non-engaging part 2 of the tooth is a horizontally arranged planar segment 201 and an inclined segment 202. The included angle between the planar segment 201 and the inclined segment 202 is an obtuse angle. The bottom surface of the recessed part 3 is designed as a planar surface, which is a relatively simple design. The flat bottom surface can stably bear the grease, form a uniform oil film, and provide continuous and effective lubrication. In addition, the planar surface can effectively disperse stress and avoid stress concentration. After the planar surface and the side wall are transitioned by an arc, the overall torsional and deformation resistance is very strong, the durability is high, the planar cavity of the stamping or die-casting mold is the simplest to process, the precision is easy to control, the mold life is long, the production efficiency is high, and it is most suitable for mass production. When electroplating or spraying, the coating thickness is the most uniform on the planar surface, and the appearance is flat and beautiful. In contrast, the grooves on the planar surface are not easy to trap dirt and are easier to clean.

[0046] In some embodiments, the bottom surface of the recessed portion 3 is an arc-shaped surface, which is recessed in the direction toward the meshing base 1 or protrudes in the direction away from the meshing base 1.

[0047] For details, please refer to the appendix. Figure 3 Appendix Figure 4 Appendix Figure 5 With appendix Figure 6 The second and third types of teeth provided in this application have an arc-shaped bottom surface in the recessed part 3. When the arc-shaped surface is recessed in the direction of the meshing base 1, it has the following advantages: due to surface tension and geometry, the lubricant will naturally gather at the lowest point of the concave surface instead of flowing to the edge, which helps to retain the lubricant in the most critical chain tooth friction area; a reasonable arc-shaped concave surface is similar to an arch structure, which can improve the compressive strength in a specific direction. When the arc-shaped surface bulges in the direction away from the meshing base 1, under the premise of ensuring the size of the groove opening (providing space for the chain teeth), the convex surface can remove more material to achieve maximum weight reduction. According to the stress analysis, if some areas are subjected to less stress, the convex surface design can "hollow out" these non-critical areas and distribute the material more reasonably on the frame and key structure that require strength. In addition, the convex surface has a "guiding" effect, which can make it easier for dust, fine fibers and other dirt that enter the recessed part 3 to be discharged with the movement of the pull head, and has a certain self-cleaning effect.

[0048] In some embodiments, the bottom surface of the recessed portion 3 is a contoured surface including a wavy shape.

[0049] For details, please refer to the appendix. Figure 7 With appendix Figure 8This is the fourth type of tooth provided in this application. It is a more functional design and is usually found on high-end or professional zippers. The wavy grooves create a larger surface area and countless tiny oil reservoirs, which can absorb more lubricant and lock it in firmly through surface tension. It can maintain lubrication for a longer time even in harsh environments (such as rain). The wavy texture can act as an "oil guide groove" to guide and distribute the lubricant more evenly to the entire friction surface. The regular wavy structure (especially the structure similar to triangular ribs or sine waves) can provide a "corrugated plate" effect, which can significantly improve the bending stiffness of the surface without increasing the thickness, while achieving lightweighting. The complex surface can disrupt the flow and vibration frequency of the lubricant, which can sometimes help reduce noise during the zipping process.

[0050] In some embodiments, two recesses 3 are provided, with the other recess 3 located on the side of the planar segment 201 away from the inclined segment 202.

[0051] For details, please refer to the appendix. Figure 9 To be continued Figure 12 The recessed portion 3 has two parts. One part is located at the connection between the engaging base 1 and the non-engaging portion 2, as described above. The other recessed portion 3 is located at the end of the planar section 201 on the side away from the inclined section 202, which can form a segmented structure and increase the design aesthetics. It should be noted that the recessed portion 3 has two forms: one is that it partially covers the inclined section 202, which can form a four-segment design, i.e., attached... Figure 9 With appendix Figure 10 The fifth type of tooth shown is another type that completely covers the inclined segment 202, forming a three-segment design, as shown in the attached diagram. Figure 11 With appendix Figure 12 The sixth type of tooth shown has a different design.

[0052] Based on the above embodiment, the maximum depth of the recessed portion 3 is less than one-fifth of the thickness of the non-engaging portion 2.

[0053] For details, please refer to the appendix. Figure 4 Or attach Figure 6 The deepest part of the recess 3 should be less than one-fifth the thickness of the non-engaging part 2. This design reduces the risk of tooth displacement during processing, provides ample processing space for subsequent machining on the subtractive surface, and avoids wear of the machined material during use. The bottom shape of the recess 3 is formed during secondary processing, which allows for quality reduction and material recycling without affecting the tooth thickness. It also provides a base for subsequent processing on the subtractive surface, such as laser engraving and coating, preventing wear of the protruding elements during use.

[0054] Based on the above embodiment, the length of the recessed portion 3 is less than half the length of the planar segment 201 and the sum of the length of the inclined segment 202.

[0055] Specifically, in the direction of tooth length (i.e., the direction perpendicular to the length of the chain), the length of the recessed portion 3 is less than half the length of the flat section 201 and the sum of the length of the inclined section 202. The main purpose of this design is to ensure that the teeth have enough working surface to contact the pull head, and also to make the decorative effect sufficiently obvious.

[0056] Based on the above embodiment, the surface of the non-engaging part 2 is provided with a removable color film 4, the color of which is different from the body color of the non-engaging part 2.

[0057] Specifically, a colored film is applied to the surfaces of both the planar section 201 and the inclined section 202. The color of the colored film is different from the color of the non-engaging part 2 to create a color separation effect. In the zipper production process, after the zipper chain is produced, it enters the coating process. A colored film 4 with a different color from the chain can be selected for decorative processing. After the coating is cured, it enters the polishing machine for material reduction and tooth repair to achieve the desired color gradient effect.

[0058] Based on the above embodiments, the interior of the recessed portion 3 is provided with a textured surface or a coating.

[0059] Specifically, after the material reduction process, the depth and length of the recessed portion 3 are limited. The interior of the recessed portion 3, especially its bottom surface, is laser-engraved or coated to further improve the aesthetics of the teeth without affecting the structural strength.

[0060] In addition to the teeth mentioned above, this utility model also provides a zipper that includes the teeth disclosed in the above embodiments. For the structure of other parts of the zipper, please refer to the prior art, which will not be repeated here.

[0061] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0062] The foregoing has provided a detailed description of the teeth and zipper provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core idea of ​​this utility model.
