Description

TECHNICAL FIELD

[0001] The present application relates to the field of zippers, and in particular to a concealed zipper. BACKGROUND

[0002] Zippers are common in our daily life, and concealed zippers are developed for better hiding the zipper teeth. The existing concealed zipper includes a puller, a pair of zipper tapes and a pair of zipper teeth. Figure 1 As shown in the figure, the puller 1 includes a lower wing plate 11, a guide post 12 vertically arranged at the front end of the lower wing plate 11, an upper wing plate 13 extending rearward from the guide post 12, left and right puller side parts, each of which includes a wall part 14 and a flange part 15 connected to the wall part 14, the wall parts 14 of the two puller side parts are vertically arranged along the left and right side edges of the lower wing plate 11, and the flange parts 15 of the two puller side parts are arranged extending from the upper ends of the connected wall parts 14 to each other. As shown in the figure, the zipper tape 2 includes a garment sewing part 21, a tape folding part 22 arranged extending from one side edge of the garment sewing part 21 to the height direction of the zipper tape 2 and folded into a U shape, and a tooth mounting part 23 further arranged extending from the tape folding part 22 and equipped with the zipper teeth 3. As shown in the figure, the zipper teeth 3 are sewn together with the zipper tape 2 by sewing threads, and the pair of zipper tapes 2 abut against each other, so that the zipper teeth 3 can be better hidden. As shown in the figure, the flange part 15 and the guide post 12 have a tape passage 4 for inserting the tape folding part 22. Since the thickness of the tape folding part 22 is less than or equal to the width of the tape passage 4, after the concealed zipper is sewn to the garment, the puller 1 of the concealed zipper is pulled, and the lining 5 of the garment often inserts into the tape passage 4, resulting in the puller 1 of the concealed zipper being unable to slide, the concealed zipper having a hard feel, and other adverse conditions. Therefore, the lining 5 is turned over during sewing (as shown in the figure) or a gasket 6 is placed under the lining 5 (as shown in the figure), which is to keep the single-layer lining 5 away from the tape passage 4 of the puller. However, in this case, the operation process is complex and the cost is increased for the garment sewing factory. Figure 2 Figure 3 Figure 2 Figure 4 Figure 5 SUMMARY

[0003] In view of the above-mentioned disadvantages of the prior art, the purpose of the present application is to provide a concealed zipper which can avoid the lining from inserting into the tape passage and does not increase the operation process of garment sewing, for solving the above-mentioned problems existing in the prior art.

[0004] In order to solve the above-mentioned technical problems, the present application provides a concealed zipper, which includes a puller, a pair of zipper tapes and a pair of zipper teeth.

[0005] ​​​​​The slider comprises a lower wing plate, a guide post, an upper wing plate and two slider side parts; the guide post is vertically arranged at the front end of the lower wing plate; the upper wing plate extends rearward from the guide post; each of the slider side parts comprises a wall part and a flange part connected with the wall part; the wall parts of the two slider side parts are vertically arranged along the left and right side edges of the lower wing plate; the flange parts of the two slider side parts extend from the upper ends of the connected wall parts in the direction of approaching each other; the zipper teeth are arranged between the lower wing plate and the flange parts;

[0006] The zipper tape comprises a garment sewing part, a tape folding part arranged along the height direction of the zipper tape from one side edge of the garment sewing part and folded into a U-shaped form, and a tooth mounting part arranged from the side of the tape folding part away from the garment sewing part and connected with the zipper teeth; the flange part and the guide post have a tape passage for the insertion of the tape folding part; the garment sewing part has a multiple weaving structure thereon, the thickness of the garment sewing part is greater than the thickness of the tooth mounting part, and the multiple weaving structure is arranged along the length direction of the zipper tape.

[0007] The garment sewing part has a multiple weaving structure thereon, the thickness of the garment sewing part is greater than the thickness of the tooth mounting part, and after the lining of the garment is sewn with the garment sewing part, the thickness of the garment sewing part enables the lining of the garment to be away from the tape passage, thereby avoiding the insertion of the lining into the tape passage. Since the multiple weaving structure is formed on the garment sewing part when the zipper tape is woven, the insertion of the lining into the tape passage can be prevented without increasing the operation process of the garment sewing.

[0008] Preferably, one end of the garment sewing part connected with the tape folding part abuts against the guide post. Since the thickness of the tape folding part is less than or equal to the width of the tape passage, there is a gap between the garment sewing part and the guide post, and this structure enables the gap to be blocked, further avoiding the insertion of the lining into the tape passage.

[0009] Preferably, the tape folding part comprises an upper folding part and a lower folding part connected in sequence from top to bottom, the upper folding part is connected with the garment sewing part, the thickness of the upper folding part is equal to the thickness of the garment sewing part, and the upper folding part has a multiple weaving structure thereon. The multiple weaving structure on the upper folding part can block the gap between the garment sewing part and the guide post, thereby better preventing the insertion of the lining of the garment into the tape passage.

[0010] Further, the height of the upper folding part is less than or equal to one half of the height of the tape folding part. This structure can ensure that the multiple weaving structure blocks the gap while avoiding the situation that the tape folding part is completely made of the multiple weaving structure and is stuck in the tape passage, so as to maintain the normal movement of the slider.

[0011] Preferably, the garment sewing part comprises a main body connecting part and a main body extending part connected with each other, the main body connecting part is connected with the tape bending part, and the main body connecting part is directly above the flange part; the multi-woven structure is arranged on the main body connecting part. This structure enables the multi-woven structure to be directly above the flange part, so that the lining of the garment can be kept away from the tape channel.

[0012] Further, the width of the main body connecting part is greater than or equal to the width of the flange part. This structure can ensure that the lining of the garment is inserted into the tape channel.

[0013] Preferably, the multi-woven structure comprises at least two layers of fabric parts connected with each other, so that the multi-woven structure is compact in structure.

[0014] Further, the multi-woven structure comprises two layers of fabric parts.

[0015] Preferably, the multi-woven structure is a bag-shaped woven structure, which facilitates the processing of the multi-woven structure.

[0016] The invisible zipper of the present application can prevent the lining from being inserted into the tape channel, avoid the occurrence of the bad conditions that the puller of the invisible zipper cannot slide and the invisible zipper feels hard, and does not increase the operation process of garment sewing, so that the garment processing enterprise does not need to increase the additional sewing cost.

Figure 5 The top and bottom directions on the paper.

[0080] Example 1

[0081] like Figures 5 to 9 As shown, the concealed zipper of this embodiment includes: a zipper pull 100, a pair of zipper tapes 200 and a pair of zipper teeth 300;

[0082] The zipper pull assembly 100 includes: a lower wing plate 110, a guide post 120, an upper wing plate, and two zipper pull sides; the guide post 120 is erected at the front end of the lower wing plate 110; the upper wing plate extends rearward from the guide post 120; each zipper pull side includes a wall portion 141 and a flange 142 connected to the wall portion 141; the wall portions 141 of the two zipper pull sides are erected along the left and right side edges of the lower wing plate 110; the flanges 142 of the two zipper pull sides extend from the upper end of the connected wall portions 141 in a direction toward each other; the zipper teeth 300 are located between the lower wing plate 110 and the flanges 142;

[0083] The zipper tape 200 comprises a garment sewing portion 210, a tape bending portion 220 extending from a side edge of the garment sewing portion 210 in the height direction of the zipper tape 200 and being bent into a U shape, a tooth mounting portion 230 extending from a side of the tape bending portion 220 away from the garment sewing portion 210 and being connected with the zipper teeth 300, and a tape channel 150 between the flange 142 and the guide post 120 for the tape bending portion 220 to be inserted. The garment sewing portion 210 has a multi-braid structure 400, the thickness T1 of the garment sewing portion 210 is greater than the thickness T2 of the tooth mounting portion 230, and the multi-braid structure 400 is arranged along the length direction of the zipper tape 200.

[0084] The garment sewing portion 210 has the multi-braid structure 400, the thickness T1 of the garment sewing portion 210 is greater than the thickness T2 of the tooth mounting portion 230, and after the lining 500 of the garment is sewn with the garment sewing portion 210, the thickness T1 of the garment sewing portion 210 enables the lining 500 of the garment to be away from the tape channel 150 between the flange 142 and the guide post 120, thereby avoiding the lining 500 from being inserted into the tape channel 150. Since the zipper tape 200 is integrally formed, the multi-braid structure 400 is formed on the garment sewing portion 210 when the zipper tape 200 is braided, and therefore the garment processing enterprise can directly sew the lining 500 with the garment sewing portion 210, thereby preventing the lining 500 from being inserted into the tape channel 150 without increasing the operation process of garment sewing.

[0085] The end of the garment sewing portion 210 connected with the tape bending portion 220 abuts against the guide post 120. Since the thickness of the tape bending portion 220 is less than or equal to the width of the tape channel 150, there is a gap between the garment sewing portion 210 and the guide post 120, and this structure enables the gap to be blocked, thereby further avoiding the lining 500 from being inserted into the tape channel 150. In this embodiment, the guide post 120 comprises an upper post portion 122 and a lower post portion 121 connected with the lower end of the upper post portion 122, and the end of the garment sewing portion 210 connected with the tape bending portion 220 abuts against the upper post portion 122, so that the lining 500 cannot enter the tape channel 150.

[0086] The garment sewing portion 210 comprises a main body connecting portion 211 and a main body extending portion 212 connected with each other, the main body connecting portion 211 is connected with the tape bending portion 220 and is directly above the flange 142, and the multi-braid structure 400 is arranged on the main body connecting portion 211. This structure enables the multi-braid structure 400 to be directly above the flange 142, so that the lining 500 of the garment can always be away from the tape channel 150.

[0087] The width W1 of the main body connecting portion 211 is greater than or equal to the width W2 of the flange member 142. This structure can ensure that the lining 500 of the garment is inserted into the tape passage 150. In this embodiment, the width W1 of the main body connecting portion 211 is greater than the width W2 of the flange member 142.

[0088] In this embodiment, the tape bending portion 220 and the tooth mounting portion 230 are each woven by two single threads as a group of weft threads 402 and warp threads 401, and the tape bending portion 220 and the tooth mounting portion 230 each consist of 2 / 2 weave in which the warp threads 401 alternately run on the upper side of the two groups of weft threads 402 and on the lower side of the two groups of weft threads 402.

[0089] As shown in Figures 6 to 8 , in order to facilitate the processing of the multi-weave structure 400, the multi-weave structure 400 is a bag-shaped weave structure. The bag-shaped weave structure includes an upper weave portion 410 and a lower weave portion 420; the first end portion 411 of the upper weave portion is connected to the first end portion 421 of the lower weave portion, and the second end portion 412 of the upper weave portion 410 is connected to the second end portion 422 of the lower weave portion 420. The upper weave portion 410 and the lower weave portion 420 have the same structure. The upper weave portion 410 consists of 1 / 3, 3 / 1 weave in which the upper warp threads 401 run on the lower side of one group of weft threads 402 and on the upper side of three groups of weft threads 402, and the lower warp threads 401 run on the lower side of three groups of weft threads 402 and on the upper side of one group of weft threads 402. After each weft thread 402 is woven from the first end portion 411 of the upper weave portion to the second end portion 412 of the upper weave portion 410, each weft thread 402 is folded back so that each weft thread 402 is woven from the second end portion 422 of the lower weave portion 420 to the first end portion 421 of the lower weave portion.

[0090] In this embodiment, the thickness T1 of the garment sewing portion 210 is the maximum thickness of the garment sewing portion 210.

[0091] The invisible zipper of the present application can prevent the lining 500 from being inserted into the tape passage 150, avoiding the occurrence of adverse conditions such as the slider 100 of the invisible zipper being unable to slide and the invisible zipper having a hard feel; using the invisible zipper does not increase the operation process of garment sewing, so the garment processing enterprise does not need to increase additional sewing cost.

[0092] Example 2

[0093] As shown in Figure 10 , Figure 11 and Figure 6As shown, the difference between this embodiment and Embodiment 1 is that the fabric tape folding portion 220 includes an upper folding portion 221 and a lower folding portion 222 connected sequentially from top to bottom. The upper folding portion 221 is connected to the garment sewing portion 210, and the thickness T3 of the upper folding portion 221 is equal to the thickness T1 of the garment sewing portion 210. The upper folding portion 221 has a multi-layered weave structure 400. The multi-layered weave structure 400 on the upper folding portion 221 can seal the gap between the main body connecting portion 211 and the guide post 120, which can better prevent the garment lining 500 from being inserted into the fabric tape channel 150.

[0094] In this embodiment, since the fabric tape folded portion 220 adopts a multi-braided structure 400, it may get stuck in the fabric tape channel 150, which could easily prevent the pull head 100 from being pulled normally. By making the height of the upper folded portion 221 less than or equal to half the height of the fabric tape folded portion 220, it is possible to ensure that the multi-braided structure 400 blocks the gap while avoiding the situation where the pull head 100 cannot be pulled normally due to the fabric tape folded portion 220 getting stuck in the fabric tape channel 150.

[0095] In this embodiment, the multiple braided structure 400 of the upper folded portion 221 can be closer to the guide post 120, and the multiple braided structure 400 of the upper folded portion 221 can abut against the guide post 120. Compared with the invisible zipper of Embodiment 1, when the invisible zipper is used in scenarios with greater lateral tension, such as on tight-fitting clothing or car seat covers, a greater force will be applied to the zipper tape 200 in the lateral direction. At this time, the multiple braided structure 400 of the upper folded portion 221 is closer to and abuts against the guide post 120. Even if a part of the multiple braided structure 400 on the upper folded portion 221 is pulled outward, a part of the multiple braided structure 400 on the upper folded portion 221 still abuts against the guide post 120 to prevent the sewn object from getting stuck.

[0096] Example 3

[0097] like Figure 12 As shown, the difference between this embodiment and Embodiment 1 is that the multi-woven structure 400 includes at least two connected fabric portions 430, resulting in a compact structure. In this embodiment, the multi-woven structure 400 includes two fabric portions 430, each of which is a single-layer weave. Each single-layer weave is formed by the interlacing of warp threads 401 and weft threads 402, and adjacent fabric portions 430 are repeatedly woven together by the weft threads 402, thus connecting adjacent fabric portions 430 together. The multi-woven structure 400 may also include three fabric portions 430, which are not shown in the figure.

[0098] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0099] The above embodiments are only illustrative of the principles of the present application and its efficacy, and are not intended to limit the present application. Any modification or change made by any person skilled in the art without departing from the spirit and scope of the present application shall be covered by the claims of the present application.
