Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

 FIG. 2 is a view showing a disassembled state of a detachable zipper having a double slider according to the present invention. FIG. As shown in the figure, fluidized zipper teeth 209 are fixed to one end of the flow tape 203, and a first zip fastening box 205 and a second zip fastening box 207 are provided at the respective end portions A moving part 201 in which two sliders 211 and 213 are installed in the form of a head arrangement in the form of a head arrangement according to an installation locus of the floating zipper 209, Fixed portions 221 having fixed fastener teeth 229 corresponding to the floating zipper teeth 209 and having first and second insert pins 225 and 227 fixed to the respective ends thereof, And the moving part 201 and the fixing part 221 are sewn in a circular shape.

The first insert pin 225 and the second insert pin 227 are spaced apart from each end of the fixing tape 223 by an installation gap G, 227 are introduced into the sliders 211, 213, respectively. That is, it is preferable that the installation gap G is a space for bending the fixing tape 223 and allowing each insert pin to enter the zipper fixing box, and is spaced by the length of the slider.

The insert pins 225 and 227 and the fixing tape 223 have an installation gap G and the insert pins 225 and 227 are provided in a stepped structure from the fixing tape 223. [ Therefore, a space is formed between the first insert pin 225 and the second insert pin 227 in the process of circularly securing the fixing portion 221.

The flow tapes 203 can be sewn by a width corresponding to the installation gap G of the respective end portions and can be sewn by the thickness of the zip fastening box and the insert pins so that the first insert pins 225 and the second insert pins The space between the insert pins 227 can be blocked. This is because the zipper according to the present invention is applied to a bag or the like and prevents the contents in the bag from being separated when the space formed between the insert pins is wide.

The spacing between the insert pins may vary depending on the material and thickness of the fixing tape 223, and the installation gap G may be reduced as the fixing tape 223 is flexible and the thickness is thinner. If necessary, a separate tape may be additionally sewn on the inner side of the fixing tape 223, that is, on the inner side position corresponding to the space between the insert pins, thereby preventing the contents from escaping.

 Meanwhile, after the moving part 201 is sewn in a circular shape, the first zipper fixing box 205 and the second zipper fixing box 207 are closely contacted and fixed to each other. This is because when the clearance between the first zip fastening box 205 and the second zip fastening box 207 occurs, there is a problem that the floating zipper teeth 209 and the fastening zipper teeth 229 can not be coupled with each other. Accordingly, in the present invention, unevenness is formed so as to be mutually fitted to the respective end portions of the first zip fastening box 205 and the second zip fastening box 207, and the tight coupling is induced by tightening and compression molding.

That is, as shown in the flow chart of the zipper manufacturing process of FIG. 3, the flow tape 103 is cut by a predetermined length in step S301. Here, the set length means the length of the frame corresponding to the separation position of the bag. If necessary, the length of the zipper will be shortened when the zipper of the present invention is used so that the pocket attached to one end of the bag can be detached, but the length of the zipper will be long in order to allow the front or cover of the bag to be replaced.

Thus, when the length of the flow tape 203 is set and cut according to the design or function of the bag, the flow-through zipper 209 is aligned and inserted into one end of the flow tape 203 in step S303. This is accomplished by automated equipment for the manufacture of zippers, which are aligned and inserted and fixed according to the size, fastening structure, shape, etc. of the zipper teeth.

The flow advances to step S305 and two sliders 211 and 213 are formed to have an Arranged in head to head shape along the trajectory of the floating zipper teeth 209 after the floating zipper teeth 209 are inserted and fixed. Respectively. The provision of the sliders 211 and 213 in the form of a head arrangement allows the bag to be opened when the two sliders 211 and 213 are separated from each other.

Thereafter, the first and second zipper fastening boxes 205 and 207 are attached to the respective ends of the moving tape 203 as shown in step S307. Each outward face of the first zip fastening box 205 and the second zip fastening box 207 has a concave-convex structure to be fastened to each other. The fastening between the zipper fastening boxes is for guiding the floating zipper teeth 209 and the fastening zipper teeth 229, which are engaged by the slider, in sequence.

That is, when there is a gap between the first zip fastening box 205 and the second zip fastening box 207, the fastening of the sliders 211 and 213 at the time of fastening the moving part 201 and the fastening part 221, A repulsive force is generated. In this process, the first zip fastening box 205 and the second zip fastening box 207, which are not mutually engaged, are opened. This may cause damage or deterioration of the stitching portion between the moving portion 201 or the fixing portion 221 and the bag body and also the problem that the moving zipper teeth 209 and the fixed zipper teeth 229 can not be mutually engaged . Accordingly, the respective ends of the first zipper fixing box 205 and the second zipper fixing box 207 must be fastened to each other, and each end portion has a concave-convex structure.

Thereafter, the flow advances to step S309 to sew the flow tape 203 in a circular shape. Sewing in a circular shape enables a part of the bag such as a backpack to be detachable, thereby allowing a part of the bag to be replaced. Replacing a part of the bag is to meet the requirement of replacing by color or replacement of color. Meanwhile, in step S311, the first zip fastening box 105 and the second zip fastening box 107 are fitted to each other and then press-formed to complete the manufacture of the moving part 201. [

The manufacturing process for the fixing part 221 cuts the fixed tape 223 by the predetermined length, that is, the length of the flow tape 203, as in step S313. Then, in step S315, the fixed zipper teeth 229 are aligned and fixed to one end of the fixed tape 223 so as to correspond to the floating zipper teeth 209. The fixed zipper teeth 229 are fabricated using a manufacturing equipment of the floating zipper teeth 209. Fixed zipper teeth 229 can be produced simultaneously with the manufacture of the floating zipper teeth 209.

When the fixing zipper 229 is inserted and fixed, the insert pin is inserted at the installation gap G from the respective ends of the fixing tape 223 in step S317. In step S319, (Sewn) in a circular shape, the manufacture of the fixing portion 221 is completed.

When the moving part 201 and the fixing part 221 are manufactured through the manufacturing process, the bag part can be detachably attached by applying it as a bag such as a backpack. That is, when a part of the bag is damaged, the corresponding part can be easily replaced, and the color of a part of the bag can be changed.

4 is a photograph showing a zipper according to the present invention.

First, the removable zipper having a double slider according to the present invention is for completely separating a part, a front or a bottom of the bag from the main body, and the installation position of the zipper will be different depending on the design of the bag.

As shown in the figure, the zipper is identified as a moving part 201 and a fixing part 221 so as to be separable from each other, and opened, closed and partly opened by two sliders 211 and 213. The first zip fastening box 205 and the second zip fastening box 207 are formed into a zip fastening box 401 having an integrated structure in the course of the production process so that the moving part 201 has a circular structure. The fixing part 221 can be circular or separable, and it is determined according to the convenience of sewing according to the bag structure such as a backpack.

As shown in FIG. 5, the bag shown in the present invention is a structure in which the front, bottom, or part of the bag is completely detachable, and the front portion of the bag is completely separated in the present embodiment. Accordingly, the fixing portion 221 is sewn on the vertical surface of the front portion of the bag, and the moving portion 201 is sewn on the separation surface of the main body of the bag.

The zipper fastening box 401 is preferably positioned at the lower end of the bag and the two sliders 211 and 213 are connected to the first new pins 225 and the second insert pins 227, respectively, to fasten the moving part 201 and the fixing part 221. The sliders 211 and 213 are fastened to each other so that the user can set the opening position of the front part of the bag. That is, the front portion of the bag can be opened at an arbitrary position, and is determined by the opening position of the sliders 211 and 213. [

The sliders 211 and 213 can be completely separated from the fixing part 221. After the sliders 211 and 213 are transferred to the zip fastening box 401, By separating the second insert pin 225 and the second insert pin 227, the front portion of the bag and the main body are completely separated from each other. This is because, as shown in FIG. 6, the front part of the bag is separated from the front part of the bag when it is desired to change the outline of the bag design, when it is desired to change the color or material of the front part of the bag, The slider 211 or 213 is used to separate the front portion of the bag from the main body.
