Description

Technical Field

[0001] This invention relates to the technical field of zippers, and more particularly to a zipper with anti-theft function. Background Technology

[0002] Zippers with combination locks are an innovative product that combines the convenience of traditional zippers with security features. These zippers add a combination lock mechanism to a regular zipper, allowing users to control the opening and closing of the zipper by setting a personal password. This helps prevent unauthorized access to some extent, making them particularly suitable for situations where privacy or valuables need to be protected, such as suitcases, backpacks, and wallets.

[0003] However, while zippers with combination locks offer improved security, they also present certain security vulnerabilities. A prominent issue is that some poorly designed or manufactured combination zippers may have a weak connection in the middle of the zipper teeth, making them vulnerable to external manipulation (such as using a thin tool) to pry them open. This manipulation can not only disable the lock but also damage the zipper teeth themselves, affecting their functionality. Once the zipper teeth are damaged, even if the lock itself remains intact, the entire zipper system will fail to close effectively, thus losing its protective function. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention proposes a zipper with anti-theft function, which can solve the problem that zipper products are easily damaged by outsiders who insert and pry open the middle biting part of the zipper teeth.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This invention provides a zipper with anti-theft function, including a zipper tooth tape and a zipper head. The zipper tooth tape is provided with teeth. The zipper head moves to engage and disengage the teeth on both sides of the zipper tooth tape. The zipper tooth tape is also provided with a blocking member. The blocking member's blocking part is located above the teeth and extends towards the teeth's tooth portion. The zipper head has a tooth passage portion and a blocking part passage portion. The blocking part passage portion is located above the tooth passage portion and the tooth passage portion and the blocking part passage portion are connected. When the zipper head moves to engage the teeth, the blocking part covers the area above the teeth's tooth portion.

[0007] A preferred embodiment of the present invention is that the zipper head includes an upper plate, a lower plate, a middle plate, a first upper side plate, and a guide post. The middle plate is located between the upper plate and the lower plate. The upper plate and the middle plate are connected by the first upper side plate, and the lower plate and the middle plate are connected by the guide post.

[0008] A preferred embodiment of the present invention is that the zipper head is integrally formed.

[0009] A preferred embodiment of the present invention is that the blocking member is disposed on the chain tooth, and one end of the blocking member is connected to the chain tooth.

[0010] A preferred embodiment of the present invention is that the chain teeth and the shielding component are integrally formed.

[0011] A preferred embodiment of the present invention is that the shielding component has an L-shaped structure.

[0012] A preferred embodiment of the present invention is that a blocking member is provided on one side of the zipper teeth, and when the zipper head moves to engage the zipper teeth, the blocking member covers the other side of the zipper teeth.

[0013] A preferred embodiment of the present invention is that a blocking member is provided on both sides of the zipper teeth, namely a first blocking member and a second blocking member; the blocking part of the blocking member is located above the zipper teeth on both sides and extends towards the zipper teeth; the blocking part passing through the part includes a first passing part and a second passing part, the second passing part is located above the first passing part, the zipper teeth passing part and the first passing part are connected, and the zipper teeth passing part and the second passing part are connected.

[0014] A preferred embodiment of the present invention is that the surfaces of both the zipper head and the zipper teeth are provided with a wear-resistant coating.

[0015] A preferred embodiment of the present invention is that the outer surface of the shielding component is provided with a decorative layer.

[0016] The beneficial effects of this invention are:

[0017] This invention proposes a zipper with anti-theft functionality. In addition to the conventional teeth for the zipper head to engage and disengage, a protective element is added to the zipper teeth. This protective element is cleverly positioned above the teeth and extends towards the tooth portion. Simultaneously, the zipper head also has a tooth passage and a protective element passage, with the protective element located above the tooth passage and the two connected. This structure provides a robust physical barrier to the tooth portion, effectively preventing external tools from inserting and prying the teeth from above or the side. This significantly improves the zipper's resistance to prying and its overall durability, effectively addressing the security risks currently faced by zipper products in use.

[0029] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] This embodiment provides a zipper with anti-theft function, such as... Figure 1-7 As shown, for ease of display, Figure 5The zipper tape, omitted here, includes a zipper toothed tape and a zipper head 1. The zipper toothed tape has teeth 2. The zipper head 1, through movement, engages and disengages the teeth 2 on both sides of the zipper toothed tape. The zipper toothed tape also has a blocking element 3. The blocking element 3's blocking portion is located above the teeth 2 and extends towards the chain teeth 21 of the teeth 2. The zipper head 1 has a tooth passage portion 4 and a blocking portion passage portion 5. The blocking portion passage portion 5 is located above the tooth passage portion 4, and the tooth passage portion 4 and the blocking portion passage portion 5 are connected. When the zipper head 1 engages the teeth 2 through movement, the blocking portion covers the area above the chain teeth 21 of the teeth 2. In addition to the conventional teeth for the zipper head to engage and disengage the teeth on both sides through movement, a blocking element is specially added to the zipper toothed tape. The blocking portion of this blocking element is cleverly located above the teeth and extends towards the chain teeth, forming a physical barrier. Meanwhile, the zipper head design has also been innovated, featuring a tooth passage section and a stop passage section. The stop passage section is located above the tooth passage section, and the two are connected. This design ensures that when the zipper head moves along the zipper teeth, the teeth can smoothly pass through the tooth passage section for engagement and disengagement, while the stop of the blocking component can simultaneously pass through the stop passage section. Furthermore, during the engagement of the zipper teeth, the stop covers the top of the teeth. This prevents external attempts to pry open the zipper by inserting the middle engagement part of the zipper teeth from reaching the teeth due to the presence of the stop, thus greatly improving the safety and durability of the zipper product and effectively solving the problem of zipper products being easily damaged.

[0032] Preferably, the zipper head 1 includes an upper plate 11, a lower plate 12, a middle plate 13, a first upper side plate 14, and a guide post 15. The middle plate 13 is located between the upper plate 11 and the lower plate 12. The upper plate 11 and the middle plate 13 are connected by the first upper side plate 14, and the lower plate 12 and the middle plate 13 are connected by the guide post 15. This preferred solution has a simple structure, achieving the formation of the zipper tooth passage and the stop passage by simply adding a middle plate to the traditional zipper head. Furthermore, the middle plate, located in the zipper head, serves as the core support structure, enhancing the overall stability of the zipper head and optimizing the stress distribution among the components, reducing the risk of deformation or damage due to long-term use or improper operation. Connecting the upper plate and the middle plate via the first upper side plate, and connecting the lower plate and the middle plate via the guide post, this design ensures the smoothness and accuracy of the zipper head during sliding, reducing shaking and jamming.

[0033] Preferably, the zipper pull 1 is integrally molded. An integrally molded zipper pull means that all its components, including the zipper teeth passage, the stop passage, and other possible functional parts, are formed simultaneously during the manufacturing process, eliminating the need for subsequent assembly steps. This design not only reduces gaps between components and improves the overall strength of the zipper pull, but also avoids the risk of performance degradation or malfunction due to improper assembly. Furthermore, the integral molding technology simplifies the production process, shortens the manufacturing cycle, and reduces production costs, making the product more competitive in the market.

[0034] Preferably, the blocking element 3 is disposed on the zipper tooth 2, with one end of the blocking element 3 connected to the zipper tooth 2. This design creates a tight connection between the blocking element and the zipper tooth, making it difficult to separate or damage by external forces. The connection between one end of the blocking element and the zipper tooth not only enhances the stability of the blocking element but also ensures its smooth movement during the zipper head movement, preventing zipper malfunction due to loosening or misalignment of the blocking element. Furthermore, this design simplifies the overall structure of the zipper, reduces the number of parts, and lowers production complexity and cost.

[0035] Based on the above technical solution, preferably, the chain tooth 2 and the blocking component 3 are integrally molded. This integral molding process not only simplifies the production process and reduces production costs, but more importantly, it ensures a seamless connection between the chain tooth and the blocking component, avoiding performance degradation or safety hazards caused by gaps or looseness between components. The integrally molded chain tooth and blocking component are structurally more robust and durable, and can more effectively resist external damage, such as prying or cutting attempts.

[0036] Specifically, in this embodiment, the zipper head and the zipper teeth and the cover are integrally molded using injection molding, with ABS as the material. ABS material has excellent impact strength, heat resistance, and chemical corrosion resistance, capable of withstanding friction, collisions, and compression during daily use, ensuring the long-term stable operation of the zipper head. At the same time, ABS material has good processing performance, is easy to injection mold, can meet the design requirements of complex structures, and has a smooth surface, facilitating subsequent surface treatments such as spraying and electroplating. Furthermore, ABS material also has good environmental performance, meeting modern consumers' expectations for green and sustainable products.

[0037] Preferably, the shield 3 has an L-shaped structure. The L-shaped structure provides more comprehensive and effective protection. Firstly, the longer arm of the L-shape covers the top of the chain teeth, effectively preventing external tools from inserting and prying the chain teeth from above, thus greatly reducing the risk of zipper damage. Secondly, the shorter arm of the L-shape is close to one side of the chain teeth, forming an additional protective barrier. Even if someone attempts to damage it from the side, this barrier will make it difficult to succeed. Furthermore, the L-shaped design balances aesthetics and practicality, providing sufficient protection without adding excessive volume or weight.

[0038] In this embodiment, a cover 3 is provided on one side of the zipper teeth. When the zipper head 1 moves to engage the zipper teeth 2, the cover 3 covers the other side of the zipper teeth. First, the introduction of the cover significantly enhances the anti-theft performance of the zipper. The cover can cover the other side of the zipper teeth, making it difficult for external tools to directly contact the zipper teeth, thereby effectively preventing the zipper from being illegally pried open or unlocked. This design not only improves the security of the zipper but also provides users with a more reassuring user experience. Second, the design of the cover also has a certain aesthetic appeal. The cover can be customized according to the style and color of the zipper to coordinate with the overall style of the zipper and enhance the overall aesthetics of the product. In addition, the cover also has a certain protective function. During the use of the zipper, the zipper teeth may be damaged due to friction or impact. The presence of the cover can reduce the direct contact between the zipper teeth and the outside world, thereby reducing the risk of damage to the zipper teeth and extending the service life of the zipper.

[0039] Preferably, the shielding parts 3 of adjacent zipper teeth are tightly fitted together. This design greatly enhances the sealing and security of the zipper. In traditional zippers, the gaps between the teeth often become potential channels for foreign objects to enter, and may also become weak points for prying open the zipper. However, the tightly fitted shielding parts of adjacent teeth effectively fill these gaps, forming a continuous and seamless protective layer, significantly improving the zipper's ability to resist external prying. In addition, combined with the decorative layer design in the above embodiment, the crotches of each tooth can be combined to form a coherent picture, giving the product a unique aesthetic appeal while improving protection and security.

[0040] Preferably, both the zipper pull 1 and the zipper teeth 2 have a wear-resistant coating on their surfaces. This wear-resistant coating is typically made of polymer or ceramic materials, possessing extremely high hardness and wear resistance, effectively resisting friction and wear during daily use and protecting the zipper pull itself from damage. Simultaneously, the wear-resistant coating also improves the smoothness of the zipper pull surface, reducing sliding resistance and making the zipper pull slide more smoothly and silently. Furthermore, the wear-resistant coating also has a certain degree of anti-corrosion properties, preventing the zipper pull from being damaged due to long-term exposure to humid or corrosive environments. In this embodiment, PTFE is sprayed to form the wear-resistant coating on the surfaces of the zipper pull and zipper teeth.

[0041] Example 2

[0042] This embodiment provides a zipper with anti-theft function, the zipper head of which is as follows: Figure 8 As shown, the basic structure of the zipper teeth is the same as in Embodiment 1. The difference is that both sides of the zipper teeth are provided with blocking members 3, namely a first blocking member and a second blocking member. The blocking parts of the blocking members 3 are located above the zipper teeth 2 on both sides and extend towards the tooth portion 21 of the zipper teeth 2. The blocking part 5 includes a first passing part 51 and a second passing part 52. The first blocking member passes through the first passing part 51, and the second blocking member passes through the second passing part 52. The second passing part 52 is located above the first passing part 51. Correspondingly, the height of the second blocking member is also higher than the height of the first blocking member. The tooth passing part 4 is connected to the first passing part 51, and the tooth passing part 4 is connected to the second passing part 52. This design further enhances the anti-theft performance of the zipper. The first blocking member and the second blocking member block the zipper teeth from both sides, forming double protection, making it more difficult for external tools to access the zipper teeth, thereby greatly improving the security of the zipper. Secondly, the blocking part extends into the chain teeth. This design not only increases the blocking area but also makes the blocking tighter, further reducing the possibility of external tools being inserted.

[0043] Example 3

[0044] This embodiment provides a zipper with anti-theft functionality, which differs from Embodiment 1 in that the outer surface of the blocking part has a decorative layer. Adding a decorative layer to the outer surface of the blocking part in the design of the zipper teeth is a highly creative and practical improvement. The decorative layer not only enriches the visual effect of the zipper teeth but also enhances the overall aesthetics and market competitiveness of the product. By using different materials, colors, and patterns, the decorative layer can give the zipper teeth a unique personality and style, meeting consumers' demands for product personalization.

[0045] This invention has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. This invention is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims are also within the protection scope of this invention.
