Description

TECHNICAL FIELD

[0001] The present application relates to a connecting piece capable of combining or separating articles, in particular to an interconnected zipper string, and further relates to an application article using the interconnected zipper string. BACKGROUND

[0002] The zipper is one of the common clothing accessories. A common zipper generally includes a pair of left and right separated woven tape, a zipper set on the inner side of the woven tape, and a slider slidingly set on the woven tape, the slider being capable of closing or opening the zipper on the pair of woven tapes. The woven tape is generally directly woven according to the required width by using longitudinal and transverse interlaced cotton yarns, the thickness being about 0.5 mm, the woven structure being compact, and the whole woven tape being very thick and heavy. If applied to the lapel of a thin clothing such as a sun protection clothing, it will cause the lapel to obviously sag, which is very ugly. The present inventor has previously filed an invention patent application CN202010038179.5 on January 14, 2020, which discloses a thin-wing integrated zipper, including a longitudinally extending strip, and a zipper arranged at the inner side of the strip. The strip is a plastic film, and the zipper is a plastic tooth. The strip and the zipper are simultaneously injection molded by an injection molding process through an injection molding die to form an integrated zipper. The thin-wing integrated zipper has excellent softness and lightness compared with the woven tape, but the stretchability is not ideal, and the application range is very limited. SUMMARY

[0003] It is found that the strip of the thin-wing integrated zipper in the patent CN202010038179.5 is a plastic film, which has excellent softness and lightness, but the very compact structure of the plastic film cannot make the strip have ideal stretchability. The stretchability of the strip is mainly obtained by using the physical properties of the material itself. In view of the shortcomings of the prior art, the present application attempts to improve the stretchability of the zipper string from the structure and realize the light weight, and proposes an interconnected zipper string, including at least two left and right adjacent and side-by-side arranged zippers, and a spacing space between the two adjacent zippers. The feature is that a first arched bridge is arranged on the side of the tail end wall of the zipper, the first arched bridge including two first legs, the two first legs being respectively connected to the tail end walls of the two left and right adjacent zippers, so as to connect the two left and right adjacent zippers by means of the first arched bridge.

[0004] The interlocking structure of the chain tooth is various, for example, it can be the meshing structure adopted by the single chain tooth in the existing patent CN201380071882.4, that is, the structure composed of the neck and the meshing head on the single chain tooth; or it can be the sliding sleeve structure adopted by the female sliding tooth in the existing patent CN201910223612.X, that is, the structure of the female sliding tooth in the form of an open ring, thus having a female sliding tooth groove and a female sliding tooth groove opening; or it can be the sliding sleeve structure adopted by the male sliding tooth, that is, the columnar structure of the male sliding tooth inserted into the female sliding tooth groove.

[0005] The number of the chain tooth is not limited to two, but at least two, and in specific applications, it can be more than two, for example, 10 or 20. The number is set according to the meshing length of the interlocking chain tooth string.

[0006] The two adjacent chain teeth have a spacing space therebetween. The above definition of the two adjacent chain teeth does not mean that they are completely close together from left to right, and one chain tooth can move left and right relative to the other chain tooth. The chain tooth has at least a pair of left and right spaced side walls and a tail end wall between the pair of side walls, and the spacing space is formed between the side walls of the two adjacent chain teeth.

[0007] The first arcuate bridge is in the form of an arch and has a curved shape feature, so that the first arcuate bridge can be stretched or shrunk in response to the pulling or extrusion of external force, thus having a telescopic property. In one application, the two first legs of the first arcuate bridge are in the form of straight strips, and an arc-shaped or straight intermediate transition connecting portion is arranged between the two first legs; or the two first legs are in the form of straight strips and are arranged in opposite inclined positions and connected together at the top end. The structure of the first arcuate bridge is various, and is not listed one by one.

[0008] According to the above technical scheme, compared with the prior art, the beneficial technical effects of the present application are that: since the two left and right adjacent chain teeth are connected by the first arch-shaped bridge, and there is a spacing space between the two adjacent chain teeth, when the first arch-shaped bridge is connected to the collar part of the fabric such as clothes, the first arch-shaped bridge can follow the stretch and deformation of the fabric and stretch and deform together, and the chain teeth can be appropriately adjusted in position by moving left and right under the traction of the first arch-shaped bridge, thereby reducing the degree of wrinkles of the fabric. It can be seen that the above structure is beneficial to improve the stretchability of the chain tooth string. In addition, the first arch-shaped bridge not only can be the connecting body of the two adjacent chain teeth, but also can be selectively used to connect the interconnected chain tooth string to the fabric. In the application of sewing the first arch-shaped bridge to the fabric by sewing thread, the vacancy on the left and right sides of the first leg of the first arch-shaped bridge can become the space for the needle to fall, that is, the sewing needle with sewing thread can be sewn into the vacancy on the left and right sides of the first leg of the first arch-shaped bridge, so that the sewing difficulty can be reduced. Secondly, the first arch-shaped bridge has the structural feature of arch shape, which is also beneficial to reduce the weight of the interconnected chain tooth string.

[0009] Further technical solutions can also be that the chain tooth and the first arch-shaped bridge are integrally formed into a fusion body. In this way, the connection structure between the chain tooth and the first arch-shaped bridge can be simplified and strengthened. In one application, the chain tooth and the first arch-shaped bridge are made of plastic material and are integrally formed into a fusion body by injection molding process.

[0010] Further technical solutions can also be that a bending-shaped connecting strip is connected between the two first legs. In this way, the two first legs can use the connecting strip to strengthen the connection tightness between them, but the bending-shaped feature of the connecting strip can maintain the stretchability.

[0011] Further technical solutions can also be that an intermediate connecting strip connecting the side walls of the two adjacent chain teeth is arranged in the spacing space. In a natural state, the intermediate connecting strip can keep a proper distance between the two adjacent chain teeth, but when the interconnected chain tooth string bears a certain external force, the two adjacent chain teeth can still obtain a proper movement by compressing or stretching the intermediate connecting strip to adjust the distance between them. The intermediate connecting strip is an elastic strip, which can be a plastic strip, a cotton strip, a rubber strip, etc.

[0012] Further technical solutions can also be that the fastener has a tooth surface, and a stepped stopper for lapping with the fabric is arranged on the tooth surface. The tooth surface is the surface of the fastener, and the stepped stopper is arranged on the tooth surface. On the one hand, it is convenient for the processing and forming of the stepped stopper, and on the other hand, it is convenient for the lapping of the fabric with the stepped stopper, controls the lapping depth of the fabric with the fastener, and is also applicable to the fabric with different thicknesses, greatly improving the versatility of the fastener. The fabric can be woven fabric, artificial leather, non-woven fabric, etc.

[0013] Further technical solutions can also be that the first arcuate bridge includes at least two first arcuate bridges arranged side by side, and the two first arcuate bridges are connected together by sharing the same first leg.

[0014] Further technical solutions can also be that the first arcuate bridge includes at least two first arcuate bridges arranged side by side, and the second arcuate bridge is arranged on the side of the first arcuate bridge. The second arcuate bridge includes two second legs, and the two second legs are respectively connected to the two first arcuate bridges arranged side by side, so as to connect the two first arcuate bridges arranged side by side by means of the second arcuate bridge.

[0015] Further technical solutions can also be that the first arcuate bridge and the second arcuate bridge are integrally formed into a fusion body. In this way, the connection structure between the first arcuate bridge and the second arcuate bridge can be simplified and strengthened. In one application, the first arcuate bridge and the second arcuate bridge are made of plastic material and are integrally formed into a fusion body by injection molding process.

[0016] Further technical solutions can also include a puller, the puller includes an upper cover plate, a lower cover plate, and a fastener channel formed between the upper cover plate and the lower cover plate. Side wings capable of extruding the tail end wall of the fastener are arranged on both sides of the upper cover plate. When the fastener slides in the fastener channel, the side wings float above the first arcuate bridge and slide. In this way, when the fastener slides in the fastener channel, the side wings are not easy to touch the first arcuate bridge and affect the sliding smoothness, and are not easy to scratch the first arcuate bridge and damage the appearance of the first arcuate bridge.

[0017] In addition, the application also proposes an application product, characterized by comprising a fabric and the interconnected fastener string, and the interconnected fastener string is connected to the fabric. The application product can be a garment, a containing bag, or a seat cover, etc.

[0018] Further technical solutions can also include a sewing line, and the sewing line sews the first arcuate bridge or the second arcuate bridge of the interconnected fastener string and the fabric together.

[0019] Due to the above features and advantages of the present application, it can be applied to the interlinked string of fasteners and the application product. BRIEF DESCRIPTION OF DRAWINGS

[0033] The following details each necessary specific implementation detail structure and method. Except where it is explicitly stated that they are equivalent or alternative implementation schemes, the various implementation details disclosed below can be selectively applied or combined in one embodiment even if they are not directly related or synergistic in terms of function.

[0034] First implementation method

[0035] like Figure 1 As shown, an interconnected chain tooth string 100 includes at least two chain teeth 1 arranged side-by-side, adjacent to each other. The number of chain teeth 1 can be at least two, such as 2, 10, or 20, depending on the meshing length of the interconnected chain tooth string 100. In this embodiment, the chain tooth string 100 includes six chain teeth 1. Each chain tooth 1 is an element capable of connecting with other chain teeth to open or close the opening or closing portion of the article. The connection structure of the chain teeth 1 is diverse. For example, it can be the meshing structure used in a single chain tooth in existing patent CN201380071882.4, i.e., the structure composed of a neck and a meshing head on the single chain tooth; or the sliding sleeve structure used in a female sliding tooth in existing patent CN201910223612.X, i.e., the female sliding tooth is an open ring shape with a female sliding tooth groove and a female sliding tooth groove opening; or the sliding sleeve structure used in a male sliding tooth, i.e., the male sliding tooth has a columnar structure that inserts into the female sliding tooth groove. Furthermore, there is a gap 10 between two adjacent chain teeth 1, as defined above, meaning that two adjacent chain teeth 1 are not completely side-to-side, and one chain tooth can move left and right relative to the other chain tooth. Each chain tooth 1 has at least a pair of left and right sidewalls 12 and a tail wall 13 located between the pair of sidewalls 12, and the gap 10 is formed between the sidewalls 12 of two adjacent chain teeth 1.

[0036] The first arched bridge 2 is arranged at the side of the tail end wall 13 of the chain tooth 1, and has two first legs, which are respectively connected to the tail end walls 13 of two left and right adjacent chain teeth 1, so as to connect the two left and right adjacent chain teeth 1 by means of the first arched bridge 2. The first arched bridge 2 is arched and has a curved shape, so that the first arched bridge 2 can be stretched or shrunk in response to external pulling or extrusion, thereby having elasticity. In order to facilitate the discussion, two left and right adjacent chain teeth 1 are marked as 1' and 1", and the connection relationship between the chain tooth 1 and the first arched bridge 2 will be described in detail below. The two first legs of the first arched bridge 2 are a left first leg 21 and a right first leg 22, which are respectively in a straight strip shape, and an arc-shaped intermediate transition connecting portion 23 is arranged between the left first leg 21 and the right first leg 22. The left first leg 21 is connected to the tail end wall 13' of the chain tooth 1' on the left side, and the right first leg 22 is connected to the tail end wall 13" of the chain tooth 1" on the right side through the spacing space 10.

[0037] According to the above technical scheme, compared with the prior art, the beneficial technical effects of the present application are that: the two left and right adjacent chain teeth 1 are connected by means of the first arched bridge 2, and there is a spacing space 10 between the two adjacent chain teeth 1, so that when the first arched bridge 2 is connected to the collar part of the fabric 4 such as clothes, the first arched bridge 2 can follow the stretching and shrinking deformation of the fabric 4 and also stretch and shrink, and the chain tooth 1 can be appropriately adjusted in position left and right under the traction of the first arched bridge 2, thereby reducing the degree of wrinkles of the fabric 4. It can be seen that the above structure is beneficial to improve the elasticity of the chain tooth string 100. In addition, the first arched bridge 2 not only can be a connecting body of the two adjacent chain teeth 1, but also can be selectively used to connect the interconnected chain tooth string 100 to the fabric 4. In the application of sewing the first arched bridge 2 to the fabric 4 by the sewing thread 3, the vacancy on the left and right sides of the first leg of the first arched bridge 2 can become a space for the needle to land, that is, the needle with the sewing thread 3 can be sewn to the vacancy on the left and right sides of the first leg of the first arched bridge 2, so that the sewing difficulty can be reduced. Secondly, the arched structure of the first arched bridge 2 is also beneficial to reduce the weight of the interconnected chain tooth string 100.

[0038] Further, the fastener 1 and the first arched bridge 2 are integrally formed as a fusion. This can simplify and strengthen the connection structure between the fastener 1 and the first arched bridge 2. In one application, the fastener 1 and the first arched bridge 2 are made of plastic material, and are integrally formed as a fusion by injection molding process. In this embodiment, the first arched bridge 2 is offset to one side of the fastener 1.

[0039] Further, as shown in Figure 2 、 Figure 3 , the fastener 1 has a tooth surface, on which a stepped stopper 11 is arranged for lapping with the fabric 4. Among them, the tooth surface is the surface of the fastener 1, and the stepped stopper 11 is arranged on the tooth surface. On the one hand, it is convenient for the processing and forming of the stepped stopper 11, and on the other hand, it is convenient for the lapping of the fabric 4 with the stepped stopper 11, controls the lapping depth of the fabric 4 with the fastener 1, and in addition, it can be applied to the fabric 4 with different thicknesses, greatly improving the versatility of the fastener 1.

[0040] Further, the fastener string 100 further comprises a puller 8, which comprises an upper cover plate 81, a lower cover plate 82 and a fastener channel 83 formed between the upper cover plate 81 and the lower cover plate 82, and side wings (811, 812) capable of extruding the tail end wall 13 of the fastener 1 are arranged on both sides of the upper cover plate 81; when the fastener 1 slides in the fastener channel 83, the side wings (811, 812) float above the first arched bridge 2 to slide. In this way, a spacing is arranged between the side wings (811, 812) and the first arched bridge 2, and when the fastener 1 slides in the fastener channel 83, the side wings (811, 812) are not easy to touch the first arched bridge 2 to affect the sliding smoothness, and are not easy to scratch the first arched bridge 2 to damage the appearance of the first arched bridge 2.

[0041] Second embodiment

[0042] As shown in Figure 4a and Figure 4bAs shown, the second embodiment has a structure that is basically the same as the first embodiment. Identical structures are indicated by the same reference numerals, and their descriptions are omitted. The differences are discussed below: The interconnected chain 100a of this embodiment includes six chain teeth 1a, which do not have the stepped stop 11. An intermediate connecting strip 5 is provided in the spacing space 10 to connect the sidewalls of adjacent chain teeth 1a. This intermediate connecting strip is an elastic strip, such as a plastic strip, cotton strip, or rubber strip. In its natural state, the intermediate connecting strip 5 allows for a proper spacing between adjacent chain teeth 1a. However, when the interconnected chain 100a is subjected to a certain external force, adjacent chain teeth 1a can still adjust their spacing by compressing or stretching the intermediate connecting strip 5. Furthermore, for ease of distinction, the first arched bridge in this embodiment is designated 2a, and the first arched bridge 2a is offset to one side of the chain tooth 1a. The shape of the first arch bridge 2a is different from that of the first arch bridge 2. The left first leg 21a and the right first leg 22a of the first arch bridge 2a are not straight strips, but are composed of straight strips and mesh strips respectively. An arc-shaped intermediate transition connecting part 23a is provided between the left first leg 21a and the right first leg 22a.

[0043] Third implementation method

Identical structures are indicated by the same reference numerals, and their descriptions are omitted. The differences are discussed in detail below: a bent connecting strip 6 is also connected between the two first legs, such as the left first leg 21b and the right first leg 22b. In this way, the left first leg 21b and the right first leg 22b can utilize the connecting strip 6 to strengthen the connection between them, while also maintaining flexibility due to the bent shape of the connecting strip 6.

[0047] Fifth implementation method

[0048] like Figure 7 As shown, the fifth embodiment has a structure that is basically the same as the first embodiment. Identical structures are indicated by the same reference numerals, and corresponding descriptions are omitted. The differences are discussed below: The fifth embodiment includes at least two first arched bridges 2 arranged adjacent to each other on the left and right. A second arched bridge 7 is arranged on the side of each first arched bridge 2. The second arched bridge 7 includes two second legs, which respectively straddle the two adjacent first arched bridges 2, thereby connecting the two adjacent first arched bridges 2 by means of the second arched bridge 7. Specifically, the second arched bridge 7 includes a straight left second connecting arm 71, a right second connecting arm 72, and an arc-shaped intermediate transition connecting portion 73 connecting them. Furthermore, the first arched bridge 2 and the second arched bridge 7 are integrally formed into a fused body. This simplifies and strengthens the connection structure between the first arched bridge 2 and the second arched bridge 7. In one application, the first arched bridge 2 and the second arched bridge 7 are made of plastic and are formed into an integral fused body using an injection molding process.

[0049] Sixth implementation method

[0050] like Figure 8 As shown, the sixth embodiment is structurally similar to the fifth embodiment, with identical structures indicated by the same reference numerals, and their corresponding descriptions omitted. The differences are discussed in detail below: the intermediate transition connection 73a of the second arched bridge 7' is straight, and the intermediate transition connection 73a of two adjacent second arched bridges 7' are integrally formed into a fused body.

[0051] Seventh implementation method

[0052] like Figure 9As shown, the seventh embodiment is structurally similar to the fifth embodiment, with identical structures indicated by the same reference numerals, and their corresponding descriptions omitted. The differences are discussed below: the shapes of the first arch bridge 2c and the second arch bridge 7a differ from those of the first arch bridge 2 and the second arch bridge 7. The two first legs of the first arch bridge 2c are both straight and arranged at an angle to each other, with their tops connected together. The two second legs of the second arch bridge 7a are both straight and arranged at an angle to each other, with their tops connected together.

[0053] Eighth implementation method

[0054] like Figure 10 As shown, the eighth embodiment is structurally similar to the seventh embodiment, with identical structures indicated by the same reference numerals and their descriptions omitted. The differences are discussed below: the shape of the first arch bridge 2d differs from that of the first arch bridge 2. The two first legs of the first arch bridge 2d each include a vertical arm 21d and an inclined straight arm 22d, and the inclined straight arms 22d of the two first legs are connected together.

[0055] In addition, such as Figure 12 As shown, the present invention also proposes an application article 40, comprising a fabric 4 and the interconnected chain teeth 100b, the interconnected chain teeth 100b being connected to the fabric 4. The application article 40 can be a garment, a storage bag, or a seat cover, etc. The fabric 4 is a component of the application article, and can be, for example, woven fabric, artificial leather, non-woven fabric, etc. It also includes a sewing thread 3, which sewn the first arched bridge 2 or the second arched bridge 7' of the interconnected chain teeth 100 to the fabric 4.
