[0030] The core of the present utility model is to provide a bilateral zipper. When applied to a double-layer detachable garment of an outer shell and an inner liner, only two double-sided toothed cloth tapes need to be sewn on the outer shell, reducing the number of cloth tape sewings and improving the sewing convenience of the double-layer detachable garment of the outer shell and the inner liner.
[0031] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the bilateral zipper and the double-layer detachable garment of the present utility model will be introduced and described in detail below in conjunction with the accompanying drawings and specific implementation manners.
[0032] Combined with Figure 1 、 Figure 2 As shown, the present utility model provides a bilateral zipper, including structures such as double-sided toothed cloth tape 1, first teeth 2, and second teeth 3. The double-sided toothed cloth tape 1 plays a bearing role, and the first teeth 2 and the second teeth 3 are respectively arranged at the two side edges of the double-sided toothed cloth tape 1, and both side edges of the double-sided toothed cloth tape 1 can play a meshing role.
[0033] The first teeth 2 are arranged on one side of the first side of the double-sided toothed cloth belt 1 and partially protrude from the double-sided toothed cloth belt 1; the second teeth 3 are arranged on one side of the second side of the double-sided toothed cloth belt 1 and partially protrude from the double-sided toothed cloth belt 1; as Figure 1 , Figure 2 shown, where the right side is the first side and the left side is the second side. Figure 1 In , the first teeth 2 are located on the upper surface of the double-sided toothed cloth belt 1, and the second teeth 3 are located on the lower surface of the double-sided toothed cloth belt 1, that is, the first teeth 2 and the second teeth 3 are located on different surfaces of the double-sided toothed cloth belt 1; Figure 2 In , the first teeth 2 are located on the upper surface of the double-sided toothed cloth belt 1, and the second teeth 3 are located on the upper surface of the double-sided toothed cloth belt 1, that is, the first teeth 2 and the second teeth 3 are located on the same surface of the double-sided toothed cloth belt 1.
[0034] When the first teeth 2 and the second teeth 3 are installed on the double-sided toothed cloth belt 1, both the first teeth 2 and the second teeth 3 partially protrude from the edge of the double-sided toothed cloth belt 1 for meshing with other teeth.
[0035] The double-sided toothed cloth belt 1 can be sewn on the clothing shell 8. The double-sided toothed cloth belt 1 is sewn on the edge of the clothing shell 8. The first teeth 2 protrude from the edge of the shell 8, and the first teeth 2 serve as the front placket of the shell; the second teeth 3 are located inside the fabric of the shell 8, and the second teeth 3 can mesh with the single-sided zipper on the clothing inner liner.
[0036] When using the double-sided zipper provided by the present utility model, only two double-sided toothed cloth belts 1 need to be sewn on the shell 8, that is, one side toothed cloth belt 1 is respectively arranged at two edges of the front placket of the shell 8, with a total of two cloth belts, reducing the number of cloth belt sewing and improving the sewing convenience of the double-layer detachable clothing of the shell and inner liner. The two first teeth 2 on the shell 8 can be mutually matched and meshed to be used as a zipper on the shell 8; the two second teeth 3 on the shell 8 are respectively meshed with the single-sided zippers on the inner liner 9, so that both sides of the inner liner 9 are respectively connected to the shell 8.
[0037] For the double-layer detachable clothing adopting this double-sided zipper, only two double-sided toothed cloth belts 1 need to be sewn on the shell 8, which is the same as the sewing quantity of the ordinary single-sided zipper; two single-sided cloth belts are sewn on the inner liner 9, and a total of four cloth belts are sewn for the double-layer detachable clothing. Compared with the traditional structure that needs to sew six cloth belts, the number of sewing is reduced, and the sewing convenience of the double-layer detachable clothing of the shell and inner liner is improved.
[0038] On the basis of the above solution, the present utility model provides a specific setting form, combined with Figure 1, the first teeth 2 are arranged on the upper surface of the first side of the double-sided toothed cloth belt 1, and the second teeth 3 are arranged on the lower surface of the second side of the double-sided toothed cloth belt 1. The first teeth 2 and the second teeth 3 are located on different sides of the double-sided toothed cloth belt 1. When viewed from any side, only the first teeth 2 or the second teeth 3 can be seen completely, reducing the visual occupation and being more aesthetic. It should be noted that the upper surface and the lower surface are in the Figure 1 , Figure 2 shown aspects. When applied to clothing, usually the first teeth 2 are located on the outer side (away from the body) of the double-sided toothed cloth belt 1, and the second teeth 3 are located on the inner side (close to the body) of the double-sided toothed cloth belt 1.
[0039] In another embodiment, the first teeth 2 and the second teeth 3 are arranged on the same surface of the double-sided toothed cloth belt 1. As Figure 2 shown, the first teeth 2 are located on the upper surface of the first side of the double-sided toothed cloth belt 1, and the second teeth 3 are located on the upper surface of the second side of the double-sided toothed cloth belt 1. In this embodiment, when the first teeth 2 face outward, the second teeth 3 face the fabric, which can reduce the exposed size of the second teeth 3.
[0040] Specifically, the first teeth 2 and the second teeth 3 of the present utility model are sutured to the side surface of the double-sided toothed cloth belt 1 through stitches, and are relatively fixed through stitches.
[0041] On the basis of any of the above technical solutions and their combinations, one of the lower ends of the first teeth 2 and the second teeth 3 of the present utility model is provided with a square edge 4, and the other lower end is provided with a plug edge 5. The teeth provided with the square edge 4 are correspondingly provided with a slider 6; combined with Figure 3 , where the first teeth 2 are arranged on the right side and the second teeth 3 are arranged on the left side. The lower end of the first teeth 2 is provided with a square edge 4, and the lower end of the second teeth 3 is provided with a plug edge 5. The slider 6 is installed on the first teeth 2; combined with Figure 4 , where the first teeth 2 are arranged on the left side and the second teeth 3 are arranged on the right side. The lower end of the second teeth 3 is provided with a square edge 4, and the lower end of the first teeth 2 is provided with a plug edge 5. The slider 6 is installed on the second teeth 3. The upper ends of both the first teeth 2 and the second teeth 3 are provided with upper stops 7.
[0042] Figure 3 , Figure 4 shown two double-sided zippers are respectively installed on the two side edges of the outer shell 8. Combined with Figure 5 shown, it represents Figure 3 , Figure 4 shown schematic diagram of the meshing state of the first teeth 2 of the two double-sided zippers.
[0043] In one embodiment, the length of the first teeth 2 is greater than or equal to the length of the second teeth 3. Generally, the length of the front-opening zipper of the inner liner 9 is shorter than that of the front-opening zipper of the outer shell 8. Correspondingly, the length of the second teeth 3 can be made shorter than the length of the first teeth 2.
[0044] Combined Figure 1 、 Figure 2 As shown, the first teeth 2 and the second teeth 3 are respectively provided with ribs 10. Each tooth of the first teeth 2 is connected into one body by a rib 10, and each tooth of the second teeth 3 is connected into one body by a rib 10, which can improve the overall strength of the first teeth 2 and the second teeth 3.
[0045] Specifically, the double-sided toothed tape 1 of the present utility model is sewn on the fabric of the clothing through at least two stitches, so that the double-sided toothed tape 1 fits more closely to the clothing fabric and has stronger integrality with the clothing. The positions of the first teeth 2 and the second teeth 3 are defined by at least two stitches. There is a certain distance between the bottom of the second teeth 3 and the stitch closest to it, so that there is a certain insertion space when the second teeth 3 cooperate with the single-sided chain teeth. Combined Figure 6 As shown, the stitch close to the second teeth 3 can be non-linear. The area above the second teeth 3 is closer to the stitch, which can reduce the shaking amplitude of the upper area of the second teeth 3; a certain distance below the second teeth 3 is farther from the stitch, Figure 3 The dotted line A in [[ ]] represents the stitch close to the second teeth 3. A part of the lower end of the stitch A gradually moves away from the second teeth 3 downward, which can make it easier for the second teeth 3 to be inserted into the square of the single-sided zipper. The dotted line B represents the stitch close to the first teeth 2, and this stitch can be set at equal intervals from the first teeth 2.
[0046] The present utility model also provides a double-layer detachable clothing. Combined Figure 7 As shown, it includes a shell 8 and an inner liner 9. This double-layer detachable clothing includes the double-sided zipper of any one of the above. The double-sided toothed tape 1 is attached to the inner side of the shell 8 and sewn on the shell 8, so that the first teeth 2 serve as the front of the shell 8, and the second teeth 3 are used to engage with the single-sided zipper on the inner liner 9. Combined Figure 5 As shown, the first teeth 2 of the two double-sided zippers on the shell 8 can be engaged with each other to be used as the zipper of the shell 8; Combined Figure 6 As shown, it is a schematic diagram of the engagement between a double-sided zipper and the single-sided zipper on the inner liner 9. The two single-sided zippers of the inner liner are respectively used in cooperation with a second tooth 3, so as to relatively fix the two edges of the inner liner 9 to the shell 8.
[0047] When the temperature is low, the inner liner 9 can be installed. The inner liner 9 cooperates with the two second teeth 3 respectively, and the two first teeth 2 on the shell 8 cooperate with each other to close the shell 8, increasing the thickness of the clothing and improving the heat preservation performance. When the temperature is high, the inner liner 9 can be removed and taken out separately. The single-sided zipper of the front of the inner liner 9 can be zipped up separately, and the inner liner 9 can be used alone; the two first teeth 2 on the shell 8 cooperate with each other to close the shell 8, and the shell 8 can also be used alone.
[0048] The double-layer detachable garment provided by the present utility model further includes an independently provided double-sided zipper. The independently provided double-sided zipper is not fixed to the outer shell 8, and is used for engaging with the front of the outer shell 8 to increase the girth of the outer shell 8. Combined with Figure 8 As shown, a double-sided zipper is provided in the middle. The two teeth of the double-sided zipper are respectively engaged with the first teeth 2 on the outer shell 8 as the front, so that the middle double-sided tooth cloth tape 1 is used as a part of the surface of the garment, thereby increasing the girth of the garment. For example, it is applied to the spliced zipper of maternity clothes. Pregnant women need to buy clothes at different stages from pregnancy to childbirth. After giving birth, the maternity clothes can no longer be worn, resulting in a great waste; when the neck of a pregnant woman increases, an independent double-sided zipper can be installed separately to increase the girth of the garment; or it is applied to a mattress. In winter, it needs to be thickened, and an independent double-sided zipper needs to be spliced on the mattress, and the double-sided zipper is removed in summer.
[0049] Of course, the double-sided zipper provided by the present utility model can also be used independently. As there are more and more domestic water pipes, in the north and in a long-term low-temperature environment, the pipes are easily frozen. Usually, bags are put on the outside of the pipes. Generally, a whole zipper is sewn. Sewing a zipper on the bag will increase the cost and the wrapping property will be poor. Using the double-sided zipper provided by the present utility model to wrap around the outside of the pipe, the circumference of the pipe can be measured, and the two teeth can be directly sewn on the fabric, and the two teeth can engage with each other to wrap the pipe.
[0050] For the double-sided zipper developed by the present utility model, double-sided tooth cloth tapes are respectively installed on both sides of the front of the outer shell 8 of the garment with an inner liner, which improves the sewing efficiency and the length of the zipper can also be controlled. Double-sided zippers are installed on the left and right inner sides of the outer shell 8. There are sewing teeth on both sides of the double-sided zipper. The teeth on both sides are installed on the opposite sides of the cloth tape. One side installs the pin side, and the other side installs the square side. A pull head is installed on the square side; the left pin is combined with the right square side to form a front chain for opening and closing the front. The left square is pulled together with the inner liner pin and installed on the left inner side; the right pin is pulled together with the inner liner square and installed on the right inner side.
[0051] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
