Therefore, they should not be construed as limitations on this application.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0037] Please see Figure 1 , Figure 4 and Figure 7 The chain assembly provided in the embodiments of this application will now be described. The chain assembly is used for a zipper. The chain assembly includes a first chain 1 and a second chain 2. Both the first chain 1 and the second chain 2 are provided with a plurality of teeth 3. Each tooth 3 includes a tooth 31 and a decorative part 32 disposed on the tooth 31. The teeth 3 on the first chain 1 and the teeth 3 on the second chain 2 can mesh with each other to form at least one pair of teeth 3.

[0038] Please see Figure 8 and Figure 9 In the meshing state, the decorative portion 32 of one tooth 3 in the tooth pair is at least partially opposite to the decorative portion 32 of the other tooth 3; and the decorative portion 32 of at least one tooth 3 in the tooth pair is offset relative to its meshing tooth 31 toward a first direction, the first direction being the direction in which one tooth 3 in the tooth pair approaches the other tooth 3 along the meshing line 6.

[0039] The chain assembly is an important component of the zipper. In this embodiment, the chain assembly includes a first chain 1 and a second chain 2. The first chain 1 and the second chain 2 engage to close the zipper, and disengage to open it. The engagement of the first chain 1 and the second chain 2 is achieved through the interlocking of their teeth 3. In this embodiment, the teeth 3 include teeth 31 and decorative portions 32 disposed on the teeth 31. It should be noted that in this embodiment, the first chain 1 and the second chain 2 may include one or more teeth 3 as described in this embodiment, and may also include some other ordinary teeth 3. In this embodiment, the teeth 31 are the engaging parts of the teeth 3, and the first chain 1 and the second chain 2 are engaged with each other through the teeth 31.

[0040] In this embodiment, the tooth 3, in addition to the meshing teeth 31, also has decorative portions 32 disposed on the teeth 31. The decorative portions 32 can decorate the tooth 3. For example, decorative patterns can be set on these decorative portions 32, such as trademarks, text, and various graphics. However, it should be noted that the decorative portions 32 in this embodiment do not necessarily need to be decorated with patterns; the decorative portions 32 themselves have a certain decorative effect. The decorative portions 32 can be fixed to the teeth 31 by means of adhesive bonding, or the teeth 31 and the decorative portions 32 can be integrally formed. Since the tooth 3 is small in size, integral forming is usually preferred.

[0041] The teeth 3 on the first chain 1 and the teeth 3 on the second chain 2 can mesh with each other to form at least one pair of teeth 3. Here, a pair of teeth 3 refers to two teeth 3 having meshing teeth 31 and decorative parts 32. These two teeth 3 are located on the first chain 1 and the second chain 2 respectively. The two teeth 3 correspond to each other and can mesh with each other to form a pair of teeth 3. The number of pairs of teeth 3 can be one or more. In most cases, there are multiple pairs of teeth 3. For example, all the teeth 3 on the first chain 1 and the second chain 2 can correspond one-to-one to form a pair of teeth 3.

[0042] In the meshing state, the decorative portion 32 of one tooth 3 in a pair of teeth 3 is at least partially opposite to the decorative portion 32 of the other tooth 3. In the pair of teeth 3, one tooth 3 is located on the first chain 1, and the other tooth 3 is located on the second chain 2. Here, "opposite" means that the decorative portion 32 of one tooth 3 faces the other tooth 3. The decorative portions 32 of the two teeth 3 can be completely opposite or partially opposite. In this way, the decorative portions 32 of the two teeth 3 can be combined to form a larger decorative portion 32 when the chains are meshed, thereby increasing the usable area of ​​the decorative portion 32.

[0043] Normally, a certain gap needs to be maintained between two adjacent teeth 3 on the same side of the chain for the chain to bend properly. Therefore, the decorative parts 32 of two adjacent teeth 3 on the same side of the chain also need to maintain a certain gap, which results in a reduction in the width of the decorative parts 32. The opposing portions of the decorative parts 32 of the two teeth 3 will be reduced accordingly, which is not conducive to combining them to form a larger decorative part 32.

[0044] In this embodiment, the decorative portion 32 of at least one tooth 3 in the tooth pair 3 is offset relative to its meshing tooth 31 towards a first direction, which is the direction in which one tooth 3 in the tooth pair approaches the other tooth 3 along the meshing line 6. Figure 9For example, in a pair of teeth 3, the two teeth 3 are the first tooth 4 and the second tooth 5. For the first tooth 4, direction A is the first direction, and for the second tooth 5, direction B is the first direction. Both are arranged along the meshing line 6, but their directions are exactly opposite. The meshing line 6 is the trajectory line of the two rows of first chains 1 and second chains 2 that intersect and are tightly connected during the zipper operation, i.e., the pulling trajectory line of the zipper pull. In other words, the decorative part 32 of one tooth 3 in the pair of teeth 3 is offset relative to its tooth 31 towards the tooth 31 of the other tooth 3 in the direction of the meshing line 6. This offset means that the decorative part 32 is closer to the tooth 31 of the other tooth 3 in the direction of the meshing line 6, relative to the tooth 31 of the same tooth 3. For example, in a pair of teeth 3, the tooth 31 of one tooth 3 is in contact with the tooth 31 of another tooth 3, and its decorative part 32 may be partially intersecting with the tooth 31 of another tooth 3 in the direction of the meshing line 6, or even its decorative part 32 may cover the tooth 31 of another tooth 3.

[0045] The two teeth 3 mesh with each other through their meshing teeth 31; therefore, the position of the meshing teeth 31 is the basis for determining the relative position of the two teeth 3 during meshing. Figure 9 For example, in a tooth pair 3, the two teeth 3 are a first tooth 4 and a second tooth 5. The first tooth 4 has a first tooth 41 and a first decorative portion 42 on the first tooth 41, and the second tooth 5 has a second tooth 51 and a second decorative portion 52 on the second tooth 51. The decorative portion 32 of at least one tooth 3 in the tooth pair 3 is offset relative to its tooth 31 in a first direction. Therefore, the offset can be such that the first decorative portion 42 is offset relative to the first tooth 41 towards the second tooth 51 in the direction of the meshing line 6; or, the second decorative portion 52 is offset relative to the second tooth 51 towards the first tooth 41 in the direction of the meshing line 6; or, the first decorative portion 42 is offset relative to the first tooth 41 towards the second tooth 51 in the direction of the meshing line 6, and the second decorative portion 52 is offset relative to the second tooth 51 towards the first tooth 41 in the direction of the meshing line 6. In this case, the opposing portions of the first decorative portion 42 and the second decorative portion 52 are more numerous, thus allowing them to be combined into a larger decorative portion 32. Therefore, this embodiment can effectively increase the decorative area and enhance the decorative effect, thereby improving the aesthetics of the chain while maintaining its performance.

[0046] Please see Figure 2 and Figure 9 In some embodiments of this application, the teeth 3 include patterns disposed on the decorative portion 32, and in the meshing state, the patterns of two teeth 3 are aligned to form a combined pattern.

[0047] While the decorative section 32 itself serves a decorative purpose, adding patterns to it enhances its recognizability and aesthetics. Therefore, in this embodiment, patterns are provided on the decorative section 32. These patterns can be text, such as letters, Chinese characters, Roman letters, Latin characters, etc.; they can also be logos, such as trademarks, brand logos, symbols, etc.; or they can be various personalized patterns, such as portraits, cartoon characters, etc. The patterns can be formed using methods such as printing, spraying, engraving, or injection molding.

[0048] This embodiment utilizes the characteristic that the teeth 3 are located at the center of the two decorative parts 32, which have a large relative portion. In the meshing state, the patterns of the two teeth 3 form a combined pattern. This improves the diversity of patterns and decorative effects, providing a wide range of creative space for pattern design and enabling the creation of various visual effects.

[0049] The pattern on the decorative part 32 of the two teeth 3 in the tooth pair can be two parts of a complete pattern, that is, a complete pattern is divided into two parts, which are respectively set on the two decorative parts 32 of the tooth pair 3. When the two teeth 3 mesh, a complete pattern can be formed. Figures 7 to 9 As shown, a first pattern is provided on the first decorative part 42, and a second pattern is provided on the second decorative part 52. The first pattern can be part of the trademark, and the second pattern can be another part of the trademark; when the zipper is engaged, they can form a complete trademark. The first and second patterns can also be independent related patterns, forming a more aesthetically pleasing combined graphic when combined. For example, the first pattern may be a recessed letter, while the second pattern may be the same letter convex. Alternatively, the first and second patterns may be related human figures; when the zipper is engaged, they can come close together and combine.

[0050] Please see Figure 2 In some embodiments of this application, the decorative part 32 includes a first side 321 and a second side 322 disposed opposite to each other. The first side 321 is the side of the decorative part 32 close to the meshing side of the tooth 3. In the meshing state, the first side 321 of one tooth 3 is offset in a first direction relative to the second side 322.

[0051] The decorative portion 32 has a first side 321 and a second side 322 disposed opposite to each other, i.e., the first side 321 is the opposite side of the second side 322. The first side 321 is the side of the decorative portion 32 closer to the meshing side of the tooth 3, which is the side of the tooth 3 facing the other side when the tooth 3 is engaged. For example, a tooth 3 is located on the first chain 1, and its meshing side is the side of the tooth 3 facing the second chain 2 when the first chain 1 and the second chain 2 are engaged. Therefore, the first side 321 of the decorative portion 32 on the first chain 1 is the side facing the second chain 2, while the second side 322 is the side away from the second chain 2. Similarly, the first side 321 of the decorative portion 32 on the second chain 2 is the side facing the first chain 1, while the second side 322 is the side away from the first chain 1.

[0052] by Figure 2 For example, when teeth 3 are aligned, the first side 321 of the first decorative part 42 is located on its right side, and the second side 322 is located on its left side. The first side 321 is offset relative to the second side 322 along direction A, forming a structure that is lower on the left and higher on the right. Correspondingly, the first side 321 of the second decorative part 52 is located on its left side, and the second side 322 is located on its right side. The first side 321 is offset relative to the second side 322 along direction B, also forming a structure that is lower on the left and higher on the right. However, it should be noted that if teeth 3 are aligned, the first tooth 4 on the left is located in a higher position, and the second tooth 5 on the right is located in a lower position, then the first decorative part 42 and the second decorative part 52 will form a structure that is higher on the left and lower on the right.

[0053] In this embodiment, the first side 321 of one tooth 3 in the tooth 3 pair is offset in a first direction relative to the second side 322. The offset of the first side 321 can cause the decorative part 32 to be offset in the first direction relative to its tooth 31, thereby increasing the relative portion of the first decorative part 42 and the second decorative part 52, which can be combined to form a larger decorative part 32.

[0054] Please see Figure 2 In some embodiments of this application, the decorative part 32 has a parallelogram cross-section in the direction perpendicular to the thickness of the tooth 3.

[0055] Since the first side 321 of the tooth 3 is offset relative to the second side 322, and the first side 321 is the opposite side of the second side 322, the decorative part 32 can be designed as a parallelogram with these two sides as opposite sides, that is, the cross section of the decorative part 32 in the direction perpendicular to the thickness of the tooth 3 is a parallelogram.

[0056] Compared to other irregular structures, parallelograms are easier to design and process, and allow the decorative section 32 to provide more surface area in a limited space, thus accommodating more complex or larger patterns, and also increasing the three-dimensionality and layering of the zipper, making it more attractive.

[0057] Please see Figure 6 In some embodiments of this application, the tooth 31 includes a tooth body 311 and a head 312 connected to each other, a decorative part 32 is connected to the tooth body 311, and the head 312 is offset in the opposite direction to the tooth body 311 in the first direction.

[0058] In this embodiment, the tooth 31 includes an interconnected tooth body 311 and a head 312. The tooth body 311 is the main part of the tooth 31, which is typically connected to the chain and provides support for the head 312. The head 312 is the end part of the tooth 31, used to engage with the head 312 of another tooth 3 to achieve zipper closure. The decorative part 32 is attached to the tooth body 311, rather than the head 312, which means that the decorative part 32 does not interfere with the engagement process between the teeth 3.

[0059] Because the decorative portion 32 is offset relative to its tooth 31 in the first direction, the more the tooth 31 is offset in the opposite direction to the first direction, the closer the decorative portions 32 of the two teeth 3 in the tooth pair will be in the direction of the meshing line 6, and the more of their relative portions will be. Therefore, in this embodiment, the head 312 is offset relative to the tooth body 311 in the opposite direction to the first direction. In the tooth pair, when the head 312 of one tooth 3 meshes with the other tooth 3, the relative portions of the decorative portions 32 of the two teeth 3 can be increased, thereby improving the decorative effect.

[0060] by Figure 10 For example, the first tooth 41 includes a first tooth body 411 and a first head 412, and the second tooth 51 includes a second tooth body 511 and a second head 512. For the first tooth 41, the first head 412 is offset in the opposite direction of direction A (direction B) relative to the first tooth body 411, and the second head 512 is offset in the opposite direction of direction B (direction A) relative to the second tooth body 511. When the first tooth 41 and the second tooth 51 mesh, the first decorative portion 42 can be brought closer to the second tooth 51, and the second decorative portion 52 can be brought closer to the first tooth 41, resulting in a greater relative portion between the first decorative portion 42 and the second decorative portion 52.

[0061] The head 312 is offset in the opposite direction to the tooth body 311 in the first direction, so that the head 312 is offset in the opposite direction to the decorative part 32 in the first direction. Therefore, the position of the tooth body 311 does not need to be offset in the opposite direction to the first direction. The decorative part 32 is connected to the tooth body 311, which can ensure that there are more connection parts between the two, thereby ensuring the stability of the structure and the overall strength of the tooth 3.

[0062] Please see Figure 5In some embodiments of this application, the tooth 31 includes an interconnected tooth body 311 and a head 312, with a decorative portion 32 connected to and covering the tooth body 311. The tooth 31 comprises an interconnected tooth body 311 and a head 312. The tooth body 311 is the main body of the tooth 31, typically connected to the chain belt, and provides support for the head 312. The head 312 is the end portion of the tooth 31, used to mesh with the head 312 of another tooth 3. The more connecting portions of the decorative portion 32 to the tooth body 311, the higher the stability of the connection. Therefore, in this embodiment, the decorative portion 32 covers the tooth body 311, which can maximize the stability of the connection. Furthermore, the decorative portion 32 can also conceal the tooth body 311, thereby improving aesthetics.

[0063] Please see Figure 6 and Figure 10 In some embodiments of this application, the tooth 31 includes a tooth body 311 and a head 312 connected to each other, and a meshing groove is formed between the tooth body 311 and the head 312. The decorative part 32 at least partially covers the meshing groove. In the meshing state, the head 312 of one tooth 3 is located in the meshing groove of the other tooth 3, so that the head 312 of one tooth 3 is covered by the decorative part 32 of the other tooth 3.

[0064] In this embodiment, a meshing groove is formed between the tooth body 311 and the head 312. In most cases, both sides of the tooth body 311 and the head 312 have meshing grooves, which are used to accommodate the heads 312 of two adjacent teeth 31 on opposite sides, thereby achieving chain meshing. However, in this embodiment, the focus is on the case of two teeth 3 in a pair of teeth 3. In this embodiment, in the meshing state, the head 312 of one tooth 3 in the pair of teeth 3 is located in the meshing groove of the other tooth 3, thereby achieving meshing of the two teeth 3 in the pair of teeth 3. Figure 3 As shown, the decorative portion 32 is designed to at least partially cover the meshing groove. In the meshing state, the head 312 of one tooth 3 in the tooth pair is located in the meshing groove of the other tooth 3. Since the decorative portion 32 at least partially covers the meshing groove, the head 312 of this tooth 3 is covered by the decorative portion 32 of the other tooth 3 in the meshing state. In this way, the meshing groove can be hidden, presenting a neat visual effect. In addition, in this embodiment, since the decorative portion 32 of at least one tooth 3 in the tooth pair is offset towards the first direction relative to its meshing tooth 31, the coverage area of ​​the decorative portion 32 over the head 312 of the other tooth 3 in the tooth pair can be increased, which can reduce the risk of chain breakage after the teeth 3 are engaged.

[0065] by Figure 10For example, the first decorative part 42 of the first tooth 4 can cover more of the head 312 of the second tooth 5, and the decorative part 32 of the second tooth 5 can cover more of the head 312 of the first tooth 4, thereby effectively reducing the risk of this pair of teeth 3 bursting. When all the teeth 3 of the first chain 1 and the second chain 2 form pairs of teeth 3, the risk of the entire zipper bursting can be reduced.

[0066] Based on the above chain components, please refer to Figures 2 to 6 This application also provides a tooth 3 for a zipper, the tooth 3 including a tooth 31 and a decorative portion 32 disposed on the tooth 31, the decorative portion 32 being offset relative to the tooth 31 in the direction of the engagement line 6.

[0067] In this embodiment, the tooth 3, in addition to the meshing teeth 31, also has decorative portions 32 disposed on the teeth 31. The decorative portions 32 can decorate the tooth 3. For example, decorative patterns can be set on these decorative portions 32, such as trademarks, text, and various graphics. However, it should be noted that the decorative portions 32 in this embodiment do not necessarily need to be decorated with patterns; the decorative portions 32 themselves have a certain decorative effect. The decorative portions 32 can be fixed to the teeth 31 by means of adhesive bonding, or the teeth 31 and the decorative portions 32 can be integrally formed. Since the tooth 3 is small in size, integral forming is usually preferred.

[0068] In this embodiment, the teeth 3 can form pairs of teeth 3, which are respectively disposed on the first chain 1 and the second chain 2 of the zipper. It is important to note the relative offset direction of the decorative portion 32 and the meshing tooth 31 of the two teeth 3 in the pair. The decorative portion 32 of one tooth 3 needs to be offset towards the meshing tooth 31 of the other tooth 3, that is, the decorative portion 32 is offset relative to the meshing tooth 31 in the aforementioned first direction. In the engaged state, the decorative portion 32 of one tooth 3 in the pair of teeth 3 is at least partially opposite to the decorative portion 32 of the other tooth 3. The offset of the decorative portion 32 of at least one tooth 3 in the pair of teeth 3 relative to its meshing tooth 31 in the first direction can effectively increase the decorative area and enhance the decorative effect, thereby improving the aesthetics of the chain while maintaining its performance.

[0069] Please see Figure 2 In some embodiments of this application, the decorative part 32 includes a first side 321 and a second side 322 disposed opposite to each other. The first side 321 is the side of the decorative part 32 close to the meshing side of the tooth 3. In the meshing state, the first side 321 is offset relative to the second side 322 in the direction of the meshing line 6.

[0070] The decorative part 32 has a first side 321 and a second side 322 that are disposed opposite to each other, i.e., the first side 321 is the side of the decorative part 32 that is close to the meshing side of the tooth 3, which is the side of the tooth 3 that faces the other tooth 3 when the tooth 3 is engaged. In a tooth 3 pair, the first side 321 of one tooth 3 is offset in a first direction relative to the second side 322. This offset allows the decorative part 32 to be offset in the first direction relative to its meshing tooth 31 when the two teeth 3 form a tooth 3 pair, thereby increasing the portion of the first decorative part 42 and the second decorative part 52 that are opposite each other, and thus enabling the combination to form a larger decorative part 32.

[0071] Please see Figure 6 In some embodiments of this application, the tooth 31 includes an interconnected tooth body 311 and a head 312, with a decorative portion 32 connected to the tooth body 311. The head 312 is offset relative to the tooth body 311 in the direction of the meshing line 6. In this embodiment, the tooth 31 includes an interconnected tooth body 311 and a head 312. The tooth body 311 is the main part of the tooth 31, typically connected to the chain belt, and provides support for the head 312. The head 312 is the end part of the tooth 31, used to mesh with the head 312 of another tooth 3. Therefore, in this embodiment, the head 312 is offset relative to the tooth body 311 in the direction of the meshing line 6. When the head 312 of one tooth 3 meshes with another tooth 3, the relative portions of the decorative portions 32 of the two teeth 3 are increased, thereby improving the decorative effect.

[0072] The head 312 is offset relative to the tooth body 311, which can also offset the head 312 relative to the decorative part 32. Therefore, the position of the tooth body 311 does not need to be offset. The decorative part 32 is connected to the tooth body 311, which can ensure that there are more connection parts between the two, thereby ensuring the stability of the structure and the overall strength of the tooth 3.

[0073] Based on the aforementioned chain assembly, this application also provides a zipper, which includes the chain assembly described above. In addition to the chain assembly, a zipper typically includes components such as a slider and stopcocks. The chain assembly includes a first chain 1 and a second chain 2. Both the first chain 1 and the second chain 2 are provided with multiple teeth 3. The slider can control the engagement of the teeth 3 of the first chain 1 and the teeth 3 of the second chain 2. In this embodiment, each tooth 3 includes a tooth 31 and a decorative portion 32 disposed on the tooth 31. The teeth 3 on the first chain 1 and the teeth 3 on the second chain 2 can engage with each other to form at least one pair of teeth 3. In the engaged state, the decorative portion 32 of one tooth 3 in the pair of teeth 3 is at least partially opposite to the decorative portion 32 of the other tooth 3, allowing the decorative portions 32 of the two teeth 3 to combine to form a larger decorative portion 32 in the chain engagement state, thereby increasing the usable area of ​​the decorative portion 32. The decorative portion 32 of at least one tooth 3 in the tooth pair 3 is offset toward the first direction relative to its meshing tooth 31, which can make the opposing portion of the first decorative portion 42 and the second decorative portion 52 more, thus enabling them to be combined into a larger decorative portion 32, effectively increasing the decorative area and enhancing the decorative effect, thereby improving the aesthetics of the chain while maintaining its performance.

[0074] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
