Description

Technical Field

[0001] The utility model relates to the technology in the field of fasteners, and in particular to a fastener chain, a zipper, and a fabric product containing the zipper. Background Art

[0002] A common zipper generally includes a zipper chain composed of a pair of left and right fastener tapes and an element column installed on the zipper tape, and a slider installed on the zipper chain and opening or closing the element by sliding, and a tab pull or the like may also be installed on the slider to drive the slider to slide. Among them, the element column of the zipper chain may be provided with a top stop having a stop convex portion at one end of the length direction, and the other end may be provided with an opening part having a separable pin, a retainer pin, and a retainer box for accommodating the separable pin and the retainer box. The top stop serves as a stop position when the slider slides on the zipper chain to the end of one side, and the opening part serves as a stop position when the slider slides on the zipper chain to the end of the other side, and the other end of the zipper chain can be opened or closed by whether the separable pin and the retainer pin are connected.

[0003] In the process of sewing the zipper tape of the zipper chain onto the fabric along the length direction by a sewing machine, the zipper tape and the fabric are pressed by a sewing machine foot while the zipper chain and the fabric are moved relative to the sewing machine foot along the length direction, and a sewing needle equipped with a sewing thread is moved back and forth toward the zipper tape and the fabric through a notch on the sewing machine foot facing the chain element row, thereby sewing the zipper tape onto the fabric along the length direction by the sewing thread on the sewing needle. However, in the sewing process in which the zipper tape and the fabric are pressed by the sewing machine foot while the zipper chain and the fabric are moved relative to the sewing machine foot along the length direction, the sewing machine foot moves relatively on the zipper tape along the side of the chain element row. When the presser foot of the sewing machine moves relatively to the position of the upper stopper adjacent to the chain teeth, the convex part of the upper stopper protruding along the side direction may get stuck in the notch on the presser foot of the sewing machine facing the chain teeth, and the sewing needle moving through the notch toward the zipper tape and the fabric may hit the convex part and break, thereby reducing the smoothness during the sewing process. Therefore, it is necessary to improve the structure of the zipper chain to improve the smoothness during the sewing process and avoid damage to the sewing needle. Utility Model Content

Figure 6 yes Figure 1 The schematic diagram of the operation of sewing the other end of the zipper chain near the opening member to the fabric of the zipper-containing fabric product is shown in FIG. Figures 1 to 6 The specific structures and sewing methods of the zipper chain 100, the zipper 50, and the zipper-containing fabric product 20 of the embodiment of the present invention are described, but this is only one example, and the present invention is not limited thereto and can be adjusted according to needs.

[0066] Please refer to Figure 1 In the present embodiment, the fabric product 20 containing a zipper includes a fabric 30 and a zipper 50. The zipper 50 includes a zipper chain 100 and a slider 60. The zipper chain 100 is suitable for connecting the slider 60 to form the zipper 50, and includes a zipper tape 110, a chain element array 120, and an upper stopper 130. The zipper tape 110 extends in the up-down direction (i.e., the length direction L). The chain element array 120 is arranged on the side edge of the zipper tape 110 in the up-down direction. The upper stopper 130 is arranged at the upper end of the chain element array 120 in the up-down direction (i.e., one of the ends of the length direction L). The zipper chain 100 of the zipper 50 is suitable for being sewn along the sewing area P of the zipper tape 110 (e.g., Figure 1 The sewing area P is, for example, a strip area on the zipper tape 110 adjacent to the outer side of the chain element row 120 (i.e., one side inside the zipper tape 110) and extending along the length direction L, so that the zipper chain 100 of the zipper 50 can be sewn on the fabric 30 along the length direction L to form the zipper-containing fabric product 20. The zipper-containing fabric product 20 is, for example, clothing, bags, shoes, etc., and the fabric 30 generally refers to an object on which the zipper chain 100 of the zipper 50 can be sewn, and is not limited to woven fabrics.

[0067] Here, the zipper chain 100 of the zipper 50 includes a pair of left and right zipper tapes 110 extending in the vertical direction (i.e., the length direction L), and a pair of left and right element rows 120 arranged in the vertical direction and opposite to each other at the inner edges of the pair of left and right zipper tapes 110, and the upper stopper 130 is provided at the upper end of the element row 120 on one side in the vertical direction (i.e., one side end of the length direction L). The left and right direction corresponds to the width direction W of the zipper chain 100 and the slider 60 of the zipper 50. Although the pair of left and right zipper tapes 110 and the pair of left and right element rows 120 are shown here to constitute the zipper chain 100, in the following description, the zipper tape 110 on one side and the element row 120 on one side are taken as an example. In addition, the zipper chain 100 is sewn in a state where the element row 120 and the upper stopper 130 are already provided on the zipper tape 110. That is, after the zipper chain 100 is manufactured, the zipper chain 100 as a single product is sewn on the fabric 30. Accordingly, the zipper chain 100 is not limited to being sewn on the fabric 30 to form the zipper-containing fabric product 20 after the zipper 50 is formed (not limited to being installed with the slider 60). The present invention is not limited to this and can be adjusted according to needs.

[0068] Specifically, in this embodiment, if Figure 2 As shown, the upper stopper 130 of the zipper chain 100 is arranged at the upper end of the chain element array 120 in the vertical direction (i.e., one of the ends in the length direction L). The upper stopper 130 includes a body portion 132, a convex portion 134, and an upper stop wing portion 136. The body portion 132 is arranged at the side edge of the zipper tape 110, and the body portion 132 has a side surface 132s facing the sewing area P of the zipper tape 110 in the lateral direction (i.e., the width direction W). The convex portion 134 is formed on the body portion 132 near the upper end of the body portion 132 in the vertical direction (i.e., the end away from the chain element array 120 in the length direction L), and protrudes from the side surface 132s of the body portion 132 toward the sewing area P along the lateral direction (width direction W). The upper stop wing portion 136 is formed on the main body 132 at a lower end of the main body 132 in the vertical direction (i.e., one end in the length direction L close to the element row 120) compared to the convex portion 134, and protrudes from the side surface 132s of the main body 132 toward the sewing area P along the lateral direction (width direction W). In other words, the upper stop wing portion 136 is disposed between the convex portion 134 and the first element 122 of the element row 120. In addition, at least one of the elements 122 of the element row 120 adjacent to the upper stop 130 has an element wing portion 124, which is located on the zipper tape 110 and protrudes toward the sewing area P along the lateral direction (width direction W). Here, it is taken as an example that all the elements 122 of the element row 120 are provided with the element wing portion 124, but the present invention is not limited thereto and can be adjusted according to needs.

[0069] Correspondingly, in the present embodiment, the slider 60 is installed on the zipper chain 100, and is suitable for passing through the chain tooth array 120 installed on the zipper chain 100 by sliding, and the upper stopper 130 is used as the stop position of the slider 60 when the zipper chain 100 slides along the up-down direction (length direction L). The slider 60 includes a slider body 62, a guide column 64 provided at one end of the slider body 62 (for example, the upper end side of the up-down direction as the length direction L), and a peripheral flange 66 provided on the outer peripheral edge of the slider body 62 in the left-right direction (that is, the width direction W). The slider body 62 includes an upper wing plate and a lower wing plate, etc., and the inner side ( Figure 2 The lower wing plate of the zipper chain 100 is not shown on the side facing the paper surface. Figure 2 The inner part of the slider body 62 is presented by the upper wing plate of the slider body 62 (the side away from the paper). Furthermore, the guide column 64 is used to guide the opening and closing of the chain element row 120 during the sliding of the slider 60 relative to the zipper chain 100 along the length direction L. Furthermore, the slider 60 is installed on the zipper chain 100 in a manner that the outer peripheral flange 66 corresponds to the upper stop wing portion 136 and the chain element wing portion 124 (such as Figure 2 ), and the outer peripheral flange 66 of the slider 60 is supported on the convex portion 134 of the upper stopper 130 as a stop position when the slider 60 slides on the zipper chain 100. That is, when the slider 60 slides relative to the zipper chain 100 along the length direction L, the tooth row 120 moves in the direction of the slider 60 approaching the upper stopper 130 (for example, Figure 2 When the slider 60 slides, the slider 60 engages with each other through the guidance of the outer peripheral flange 66, and moves away from the upper stopper 130 (for example, Figure 2 When the slider 60 slides on the zipper chain 100, the slider 60 is separated from each other by the guidance of the guide column 64. In addition, the slider 60 slides toward the upper stopper 130 until the outer peripheral flange 66 rests on the convex portion 134, so that the convex portion 134 of the upper stopper 130 serves as a stopper position when the slider 60 slides on the zipper chain 100. Furthermore, a pull tab 70 or the like can be installed on the slider 60 to drive the slider 60 to slide, but the utility model is not limited to this and can be adjusted according to needs.

[0070] As an example, in this embodiment, if Figure 3As shown, the thickness of the upper stop wing portion 136 in the thickness direction T is less than the thickness of the main body portion 132 in the thickness direction T, and the thickness of the upper stop wing portion 136 is less than the thickness of the protrusion 134 in the thickness direction T. That is, when the surface of the zipper tape 110 where the main body portion 132, the protrusion 134, and the upper stop wing portion 136 are located is taken as the base plane, the upper stop wing portion 136 is lower than the main body portion 132 in the thickness direction T, and the upper stop wing portion 136 is lower than the protrusion 134 in the thickness direction T. In this way, a thickness difference (such as 0.04mm / s) is formed between the upper stop wing portion 136 and the main body portion 132, and between the upper stop wing portion 136 and the protrusion 134. Figure 3 Similarly, the thickness of the element wing portion 124 in the thickness direction T is less than the thickness of the element 122 in the thickness direction T. That is, when the surface of the zipper tape 110 where the element 122 and the element wing portion 124 are located is taken as the base plane, the element wing portion 124 is lower than the body portion 132 in the thickness direction T. In this way, a thickness difference is also formed between the element 122 and the element wing portion 124 (as shown in FIG. 1 ). Figure 3 As shown). Among them, the thickness of the upper stop wing portion 136 and the thickness of the chain element wing portion 124 are both smaller than the size of the gap in the thickness direction T of the outer peripheral flange 66 of the slider 60 for the zipper tape 110 to pass through (not shown). The thickness of the upper stop wing portion 136 and the thickness of the chain element wing portion 124 can be equal (that is, the upper stop wing portion 136 and the chain element wing portion 124 can be at the same height), but this is not a limitation. Correspondingly, the thickness of the main body portion 132 and the thickness of the chain element 122 are both greater than the size of the gap in the thickness direction T of the outer peripheral flange 66 of the slider 60. The thickness of the main body portion 132 and the thickness of the chain element 122 can be equal (that is, the main body portion 132 and the chain element 122 can be at the same height), but this is not a limitation. In addition, the thickness of the protrusion 134 is greater than the size of the gap in the thickness direction T of the outer peripheral flange 66 of the slider 60. The thickness of the protrusion 134 can be equal to the thickness of the main body 132 (ie, the protrusion 134 and the main body 132 can be of the same height), or the thickness of the protrusion 134 can be greater than the thickness of the main body 132 (ie, the protrusion 134 is higher than the main body 132), but this is not limited to this.

[0071] With the above arrangement, when the slider 60 slides relative to the zipper chain 100 along the length direction L, the outer peripheral flange 66 of the slider 60 can be formed along the area formed by the thickness difference between the chain element 122 and the chain element wing portion 124, and the thickness difference between the main body portion 132 of the upper stop member 130 and the upper stop wing portion 136 (such as Figure 2In other words, the upper stop wing 136 with a smaller thickness and the chain tooth wing 124 can pass through the gap of the peripheral flange 66, so that the peripheral flange 66 can slide relative to the zipper chain 100 along the upper stop wing 136 and the chain tooth wing 124. In this way, the arrangement of the upper stop wing 136 and the chain tooth wing 124 will not interfere with the sliding of the slider 60 on the zipper chain 100 and affect the operability of the slider 60. Correspondingly, the main body 132 with a larger thickness and the chain tooth 122 will not pass through the gap of the peripheral flange 66. In other words, the peripheral flange 66 is limited to the left and right by interfering with the main body 132 and the chain tooth 122. In this way, the slider 60 will not fall off the chain tooth row 120 of the zipper chain 100. Furthermore, when the slider 60 slides relative to the zipper chain 100 toward the upper stopper 130, the slider 60 slides toward the upper stopper 130 until the peripheral flange 66 rests on the convex portion 134 with a larger thickness, so that the convex portion 134 of the upper stopper 130 serves as a stopper position when the slider 60 slides on the zipper chain 100. However, the above description of thickness is only one example of the present invention, and the present invention is not limited thereto.

[0072] Furthermore, in this embodiment, if Figure 3 As shown, in the process of sewing the zipper tape 110 of the zipper chain 100 onto the fabric 30 along the length direction L by the sewing machine, the zipper tape 110 and the fabric 30 are pressed by the sewing machine presser foot 200 and the zipper chain 100 and the fabric 30 are moved relative to the sewing machine presser foot 200 along the length direction L (for example, Figure 3 The zipper chain 100 is sewn in a manner that the element wings 124 of each element 122 of the element row 120 and the convex portion 134 and the upper stop wing portion 136 of the upper stop member 130 face the sewing machine presser foot 200. That is, the sewing area P of the zipper tape 110 is a portion adjacent to the side surface 124s of the element wings 124 facing the sewing area P, the side surface 136s of the upper stop wing portion 136 facing the sewing area P, and the side surface 134s of the convex portion 134 facing the sewing area P along the length direction L. Thus, during the sewing process in which the zipper chain 100 and the fabric 30 are pressed by the sewing machine foot 200 and moved relative to the zipper chain 100 and the fabric 30 along the length direction L, the sewing machine foot 200 moves relatively on the zipper chain 110 along the side of the chain element row 120. Figure 3 and Figure 4As shown, the side 124s of the chain tooth wing portion 124 facing the sewing area P, and the side 136s of the upper stop wing portion 136 facing the sewing area P correspondingly constitute the first sewing guide surface S1, and the side 136s of the upper stop wing portion 136 and the side 134s of the protrusion 134 facing the sewing area P correspondingly constitute the second sewing guide surface S2.

[0073] Through the above-mentioned arrangement, in the zipper chain 100, the zipper 50, and the fabric product 20 containing the zipper of the present embodiment, the upper stop member 130 includes a main body portion 132, a protrusion 134, and an upper stop wing portion 136, and at least one of the chain teeth 122 of the chain tooth row 120 adjacent to the upper stop member 130 has a chain tooth wing portion 124, wherein the side surface 124s of the chain tooth wing portion 124 and the side surface 136s of the upper stop wing portion 136 correspondingly constitute a first sewing guide surface S1, and the side surface 136s of the upper stop wing portion 136 and the side surface 134s of the protrusion 134 correspondingly constitute a second sewing guide surface S2. In this way, the upper stopper 130 reduces the height difference between the convex portion 134 and the side surface 132s of the main body 132 by the arrangement of the upper stop wing portion 136, and during the sewing process, when the sewing machine presser foot 200 moves relatively to the position of the upper stopper 130 adjacent to the chain tooth row 120, the sewing machine presser foot 200 can move relatively under the guidance of the first sewing guide surface S1 and the second sewing guide surface S2, that is, the sewing machine presser foot 200 with the notch 202 The side edge 204 can move along the first sewing guide surface S1 and the second sewing guide surface S2 more smoothly relative to the zipper chain 100 and avoid the convex portion 134 from moving toward the recess 202, thereby preventing the convex portion 134 of the upper stopper 130 protruding along the lateral direction (width direction W) from being caught in the recess 202 facing the chain element row 120 on the sewing machine presser foot 200, thereby preventing the sewing needle 210 passing through the recess 202 from hitting the convex portion 134 and breaking. Accordingly, the zipper chain 100, the zipper 50, and the fabric product 20 including the zipper can improve the smoothness during the sewing process and avoid damage to the sewing needle 210.

[0074] Furthermore, in this embodiment, if Figure 4As shown, the upper stop wing portion 136 includes a first upper stop wing portion 136a adjacent to the protrusion 134, and a second upper stop wing portion 136b closer to the lower end of the body portion 132 (i.e., adjacent to the fastener element 122) than the first upper stop wing portion 136a, and the side surface 136sa of the first upper stop wing portion 136a corresponding to the sewing area P and the side surface 136sb of the second upper stop wing portion 136b corresponding to the sewing area P are separated from each other. That is, the upper stop wing portion 136 is provided with a notch 136c to distinguish the first upper stop wing portion 136a and the second upper stop wing portion 136b in the up-down direction (i.e., the length direction L). The notch 136c can extend along the lateral direction (i.e., the width direction W) to the side surface 132s of the main body 132, and completely separate the first upper stop wing portion 136a and the second upper stop wing portion 136b in the vertical direction (the length direction L), that is, the first upper stop wing portion 136a and the second upper stop wing portion 136b each protrude from the side surface 132s of the main body 132 along the lateral direction (the width direction W) toward the sewing area P and are not connected to each other. In this way, the upper stop wing portion 136 is divided into two smaller parts in length, and the zipper tape 110 can be prevented from floating and being uneven during the process of manufacturing the upper stop member 130 (e.g., by injection molding). Preferably, the length L1 of the notch 136c in the length direction L is smaller than the length L2 of the first upper stop wing portion 136a and smaller than the length L3 of the second upper stop wing portion 136b, so as to prevent the first upper stop wing portion 136a or the second upper stop wing portion 136b from being stuck in the notch 202 on the sewing machine presser foot 200. However, in other embodiments not shown, the upper stop wing portion 136 may also be separated only at the side 136s (i.e., the notch 136c does not extend to the side 132s of the body portion 132), so that the first upper stop wing portion 136a and the second upper stop wing portion 136b are connected to each other near the body portion 132. Alternatively, only one upper stop wing portion 136 with a longer length (i.e., no notch 136c) may be provided, and the present invention is not limited thereto and may be adjusted according to needs.

[0075] Furthermore, in this embodiment, if Figure 4As shown, the upper stop wing 136 and the convex part 134 are connected to each other in the up-down direction (i.e., the length direction L). That is, in the case where the first upper stop wing 136a and the second upper stop wing 136b are provided, the upper end side of the first upper stop wing 136a located between the convex part 134 and the second upper stop wing 136b is connected to the convex part 134. The said connection to each other may refer to being completely connected without the presence of a gap extending along the lateral direction (width direction W). In the case where only one upper stop wing 136 with a longer length is provided, the upper end side of the upper stop wing 136 is connected to the convex part 134. In this way, the upper stop member 130 can further reinforce the convex part 134 as the stop position of the slider 60 through the upper stop wing 136. In addition, there is no gap between the upper stop wing 136 and the convex part 134, so that the convex part 134 can be prevented from being stuck in the notch 202 on the sewing machine presser foot 200. However, in other embodiments not shown, a gap may be provided between the protrusion 134 and the upper stop wing portion 136 so that the protrusion 134 and the upper stop wing portion 136 are completely or partially separated in the vertical direction (i.e., the length direction L), as long as the size of the gap does not cause the protrusion 134 to be stuck in the notch 202 on the sewing machine presser foot 200. The present invention is not limited to this and can be adjusted according to needs.

[0076] In addition, in this embodiment, Figure 4 As shown, the side 132s of the protrusion 134, the side 136sa of the first upper stop wing 136a, and the side 136sb of the second upper stop wing 136b are aligned with each other. In addition, the side 124s of the tooth wing 124 is farther away from the sewing area P than the side 136sb of the second upper stop wing 136b. That is, the size of the tooth wing 124 in the lateral direction (i.e., the width direction W) is smaller than the size of the protrusion 134, the first upper stop wing 136a, and the second upper stop wing 136b in the lateral direction (width direction W). Furthermore, the lower end of the second upper stop wing 136b opposite to the protrusion 134 is provided with a rounded chamfer C1. The rounded chamfer C1 means that the lower end of the second upper stop wing 136b is formed as an arc surface, so that the movement of the sewing machine presser foot 200 can be smoothly guided. In this way, at least a portion of the first sewing guide surface S1 (the side surface 136sa of the first upper stop wing portion 136a and the side surface 136sb of the second upper stop wing portion 136b) constitutes a plane, and the second sewing guide surface S2 (the side surface 132s of the convex portion 134, the side surface 136sa of the first upper stop wing portion 136a, and the side surface 136sb of the second upper stop wing portion 136b) constitutes a plane. Preferably, the plane is parallel to the length direction L, that is, the side surface 132s of the convex portion 134, the side surface 136sa of the first upper stop wing portion 136a, and the side surface 136sb of the second upper stop wing portion 136b are aligned with each other along the length direction L, but the utility model is not limited thereto.

[0077] With the above arrangement, during the sewing process, when the sewing machine presser foot 200 moves relatively to the position of the chain element row 120 adjacent to the upper stopper 130 (i.e. Figure 3 In the state shown in the figure, the sewing machine presser foot 200 first enters the side 136sb of the second upper stop wing portion 136b smoothly from the side 124s of the tooth wing portion 124 through the round chamfer C1 provided at the lower end of the second upper stop wing portion 136b, and then smoothly passes through the first sewing guide surface S1 (at least the side 136sa of the first upper stop wing portion 136a and the side 136sb of the second upper stop wing portion 136b) which at least partially constitutes a plane. Then, the sewing machine presser foot 200 smoothly enters the side 136s of the upper stop wing portion 136 and the side 134s of the protrusion 134, thereby smoothly passing through the second sewing guide surface S2 (the side 136s of the upper stop wing portion 136 and the side 132s of the protrusion 134) which constitutes a plane. Finally, the sewing machine presser foot 200 moves along the second sewing guide surface S2 until sewing is completed, and the sewing machine presser foot 200 stops at the side of the upper stop 130 or at a position farther away from the chain element row 120 than the upper stop 130 ( Figure 4 The position closer to the upper end in the middle). Accordingly, at least a portion of the first sewing guide surface S1 and the second sewing guide surface S2 form a plane, and a round chamfer C1 is provided at the part where the side surface 136sb of the second upper stop wing portion 136b and the side surface 124s of the tooth wing portion 124 are not aligned (that is, the lower end of the second upper stop wing portion 136b), which can further improve the smoothness of the movement of the sewing machine presser foot 200 during the sewing process. In addition, the side surface of at least the part of the upper stop wing portion 136 close to the protrusion 134 (here, the side surface 136sa of the first upper stop wing portion 136a) and the side surface 134s of the protrusion 134 are aligned with each other, so that the protrusion 134 can be reinforced. However, the present invention is not limited to this, and it can be adjusted according to needs.

[0078] Correspondingly, in Figure 5In the modified example shown, the main difference between the upper stop 130A and the upper stop 130 described above is that the side 134s of the protrusion 134 of the upper stop 130A and the side 136sa of the first upper stop wing 136a are aligned with each other, and the side 136sb of the second upper stop wing 136b is farther away from the sewing area P than the side 136sa of the first upper stop wing 136a. In addition, the side 136sb of the second upper stop wing 136b and the side 124s of the element wing 124 are aligned with each other. That is, the size of the element wing 124 and the second upper stop wing 136b in the lateral direction (i.e., the width direction W) is smaller than the size of the protrusion 134 and the first upper stop wing 136a in the lateral direction (i.e., the width direction W). Furthermore, the lower end of the first upper stop wing 136a opposite to the protrusion 134 is provided with a rounded chamfer C2. The round chamfer C2 means that the lower end of the first upper stop wing portion 136a is formed into an arc surface, so that the movement of the sewing machine presser foot 200 can be smoothly guided. In this way, at least a part of the first sewing guide surface S1 (the side surface 124s of the chain element wing portion 124 and the side surface 136sb of the second upper stop wing portion 136b) constitutes a plane, and at least a part of the second sewing guide surface S2 (the side surface 136sa of the first upper stop wing portion 136a and the side surface 132s of the protrusion 134) constitutes a plane. Preferably, the plane is parallel to the length direction L, that is, the side surface 132s of the protrusion 134 and the side surface 136sa of the first upper stop wing portion 136a are aligned with each other along the length direction L, and the side surface 136sb of the second upper stop wing portion 136b and the side surface 124s of the chain element wing portion 124 are aligned with each other along the length direction L, but the utility model is not limited to this.

[0079] Through the above-mentioned arrangement, during the sewing process, when the sewing machine presser foot 200 moves relatively to the position of the chain tooth row 120 adjacent to the upper stop piece 130A, the sewing machine presser foot 200 first smoothly passes through at least a portion of the first sewing guide surface S1 that constitutes a plane (at least the side surface 124s of the chain tooth wing portion 124 and the side surface 136sb of the second upper stop wing portion 136b constitute a plane), and then smoothly enters the side surface 136s of the first upper stop wing portion 136a from the side surface 136sb of the second upper stop wing portion 136b through the round chamfer C2 provided at the lower end portion of the first upper stop wing portion 136a. Next, the sewing machine presser foot 200 smoothly enters the side surface 136sa of the first upper stop wing portion 136a and the side surface 134s of the protrusion 134, thereby smoothly passing through the second sewing guide surface S2 at least partially forming a plane (at least the side surface 136sa of the first upper stop wing portion 136a and the side surface 132s of the protrusion 134 form a plane). Finally, the sewing machine presser foot 200 moves along the second sewing guide surface S2 until sewing is completed, and the sewing machine presser foot 200 stops at the side of the upper stop 130A or at a position farther away from the chain element row 120 than the upper stop 130A ( Figure 5The first sewing guide surface S1 and the second sewing guide surface S2 are at least partially formed into a plane, and a round chamfer C2 is provided at the part where the side surface 136sa of the first upper stop wing portion 136a and the side surface 136sb of the second upper stop wing portion 136b are not aligned (i.e., the lower end of the first upper stop wing portion 136a), which can further improve the smoothness of the movement of the sewing machine presser foot 200 during the sewing process. In addition, the side surface of at least the part of the upper stop wing portion 136 close to the protrusion 134 (here, the side surface 136sa of the first upper stop wing portion 136a) and the side surface 134s of the protrusion 134 are aligned with each other, so that the protrusion 134 can be reinforced. In other embodiments not shown, when only one longer upper stop wing portion 136 is provided, for example, a round chamfer is provided at the lower end of the upper stop wing portion 136. Alternatively, the sides of the protrusion 134, the upper stop wing 136, and the fastener wing 124 may be aligned with each other, and the rounded chamfer may be omitted. It can be seen that the present invention does not limit the specific structure of the upper stop 130 and the upper stop 130A, which can be adjusted according to needs.

[0080] Please refer to Figure 1 In the present embodiment, the zipper chain 100 further includes an opening member 140. The opening member 140 is disposed at the lower end of the chain element array 120 in the up-down direction (i.e., the other end portion in the length direction L). That is to say, the upper stop member 130 and the opening member 140 are respectively disposed at the opposite end portions of the chain element array 120 of the zipper chain 100 in the length direction L. Among them, the opening member 140 includes an insert rod 142 and a seat rod 144 that are butt-jointed with each other, and a socket 146 for accommodating the insert rod 142 and the seat rod 144. The upper stop member 130 acts as a slider 60 on the zipper chain 100 and slides to one end portion on one side (for example, Figure 1 The upper end side) of the zipper chain 100 is in the stop position (as described above), and the opening member 140 as the slider 60 slides on the zipper chain 100 to the other end (for example, Figure 1 The stop position when the zipper chain 100 is in the lower end side) and the other end of the zipper chain 100 can be opened or closed by the butt joint between the insert rod 142 and the seat rod 144. Here, the zipper chain 100 of the zipper 50 is an example in which the insert rod 142 is arranged at the lower end of the left chain element row 120 and the seat rod 144 is arranged at the lower end of the right chain element row 120, and the socket 146 and the seat rod 144 are arranged integrally, so that the zipper chain 100 can be opened or closed by inserting the insert rod 142 into the socket 146 and butting against the seat rod 144 ( Figure 1140 is also provided on the zipper tape 110. That is, the zipper chain 100 is sewn as a single product on the fabric 30 after the zipper chain 100 is manufactured. However, the present invention does not limit the location and manner of the insertion rod 142, the seat rod 144, and the socket 146, which can be adjusted as needed.

[0081] Specifically, in this embodiment, if Figure 1 and Figure 6 As shown, the socket 146 of the opening member 140 is constructed as a box structure to accommodate the insertion rod 142 and the seat rod 144. Therefore, compared with the sheet-shaped zipper tape 110, the chain element array 120 provided on the zipper tape 110, the upper stop 130, the insertion rod 142, and the seat rod 144, the socket 146 is larger in size. Therefore, in the sewing process in which the zipper tape 110 and the fabric 30 are pressed by the sewing machine presser foot 200 and the zipper chain 100 and the fabric 30 are moved relative to the sewing machine presser foot 200 along the length direction L, when the sewing machine presser foot 200 moves relatively to the position of the socket 146 of the opening member 140 adjacent to the chain element array 120, in order to make the zipper tape 110 close to the fabric 30, the socket 146 needs to be flipped in the direction of the sewing machine presser foot 200 relative to the zipper tape 110 pressed by the sewing machine presser foot 200 (for example Figure 6 In other words, the zipper tape 110 is sewn with the socket 146 tilted. Here, the socket 146 has a surface 146a, an inner surface 146b, and a side surface 146s facing the sewing area P and on which the zipper tape 110 is mounted, and at least one of the surface 146a and the inner surface 146b of the socket 146 facing the sewing machine foot 200 is provided with a chamfer 146c1 connected to the side surface 146s. Here, the zipper tape 110 is sewn on the fabric 30 (the chain element array 120 and the upper stopper 130) in a manner that the surface 146a of the socket 146 faces the lower side and the inner surface 146b faces the upper side, so that the zipper chain 100 is turned over in the direction of the sewing machine foot 200 in a state where the inner surface 146b of the socket 146 faces the sewing machine foot 200 during the sewing process, and the inner surface 146b is provided with a chamfer 146c1 connected to the side surface 146s. The chamfer 146c1 is not limited to a round chamfer or a flat chamfer, as long as the chamfer 146c1 is further retreated toward the main body of the socket 146 than the intersection of the inner side 146b and the side 146s. The zipper chain 100 after sewing is sewn on the fabric 30 in a manner that the surface is exposed from the side edge of the fabric 30 and the inner side is hidden in the inner side of the fabric 30 (such as Figure 1As shown in FIG. 1 ), the zipper 50 formed by the zipper chain 100 and the slider 60 is used as a hidden zipper. However, the present invention does not limit the sewing method of the zipper chain 100 and the type of the zipper 50, which can be adjusted according to needs.

[0082] Through the above arrangement, in the zipper chain 100, the zipper 50, and the zipper-containing fabric product 20 of the present embodiment, at least one of the surface 146a and the inner surface 146b of the socket 146 of the opening member 140 facing the sewing machine presser foot 200 (for example, the inner surface 146b) is provided with a chamfer 146c1 connected to the side surface 146s. In this way, the chamfer 146c1 is further retreated toward the main body side of the socket 146 than the intersection of the extending direction of the one of the sides facing the sewing machine presser foot 200 (for example, the inner surface 146b) and the side surface 146s. During the sewing process, when the sewing machine presser foot 200 moves relatively to the position of the socket 146 of the opening member 140 adjacent to the chain tooth row 120, even if the socket 146 is flipped toward the direction of the sewing machine presser foot 200 relative to the zipper tape 110 pressed by the sewing machine presser foot 200, the chamfer 146c1 of the socket 146 will not be stuck in the space 206 on the sewing machine presser foot 200 for the sewing needle 210 to pass through, that is, the chamfer 146c1 can avoid the space 206 on the sewing machine presser foot 200 (such as Figure 6 ), thereby preventing the sewing needle 210 passing through the space 206 from hitting the socket 146 and breaking. In addition, the sewing machine presser foot 200 can move more smoothly relative to the zipper chain 100 along the chamfer 146c1 provided on the inner side 146b of the socket 146 facing the sewing machine presser foot 200. Accordingly, the zipper chain 100, the zipper 50, and the fabric product 20 including the zipper can improve the smoothness during the sewing process and prevent the sewing needle 210 from being damaged.

[0083] In other embodiments, the zipper tape 110 may be sewn onto the fabric 30 (the same applies to the chain element array 120 and the upper stopper 130) in a manner that the surface 146a of the socket 146 faces upward and the inner surface 146b faces downward, so that the zipper chain 100 is turned toward the sewing machine presser foot 200 in the sewing process with the surface 146a of the socket 146 facing the sewing machine presser foot 200, and at least the surface 146a is provided with a chamfer 146c2 connected to the side surface 146s. Alternatively, the surface 146a and the inner surface 146b of the socket 146 may be provided with a chamfer 146c1 and a chamfer 146c2 connected to the side surface 146s, respectively (such as Figure 6 As shown), the applicability of the zipper chain 100 with the opening member 140 is improved (not limited to the sewing method of the zipper chain 100). The present invention is not limited to this and can be adjusted according to needs.

[0084] In summary, in the zipper chain, zipper, and fabric product containing the zipper of the utility model, the upper stop includes a main body, a convex part, and an upper stop wing part, and at least one of the chain teeth of the chain tooth row adjacent to the upper stop has a chain tooth wing part, wherein the side surface of the chain tooth wing part and the side surface of the upper stop wing part correspond to form a first sewing guide surface, and the side surface of the upper stop wing part and the side surface of the convex part correspond to form a second sewing guide surface. In this way, the upper stop reduces the drop between the convex part and the side surface of the main body by the provision of the upper stop wing part, and during the sewing process, when the sewing machine presser foot moves relatively to the part of the chain tooth row adjacent to the upper stop, the sewing machine presser foot moves relatively under the guidance of the first sewing guide surface and the second sewing guide surface, thereby preventing the convex part of the upper stop from being stuck in the notch on the sewing machine presser foot facing the chain tooth row, thereby preventing the sewing needle passing through the notch from hitting the convex part and breaking. Preferably, the thickness of the upper stop wing is smaller than that of the body, and the thickness of the upper stop wing is smaller than that of the convex part, and the upper stop wing and the convex part are connected to each other in the up-down direction, so that the setting of the upper stop wing will not interfere with the sliding of the slider on the zipper chain, and there is no gap between the upper stop wing and the convex part, so that the convex part can be prevented from being stuck in the notch on the presser foot of the sewing machine. Accordingly, the zipper chain, zipper, and fabric product containing the zipper of the utility model can improve the smoothness during the sewing process and avoid damage to the sewing needle.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solution to deviate from the scope of the technical solution of the embodiments of the utility model.
