A zipper according to an embodiment of the present invention, a zipper tape 100 is disposed symmetrically on both sides, and a plurality of first gear (2) and second gear (4) attached to each of the zipper tape 100 in a line And first and second teeth G1 and G2 on both sides, and a slider 300 for opening and closing the first and second teeth G1 and G2 on both sides.

The zipper tape 100 is made of a durable textile material. In addition, the zipper tape 100 may be applied to a fabric coated or laminated with a layer of a water resistant or water repellent material such as a polyurethane film.

The color is determined in consideration of the color of the portion where the zipper is mounted. You can choose the same color or choose a contrasting color.

Alternatively, the zipper tape 100 may be selected to be a hydrophobic fabric that is woven using hydrophobic fibers in order to have low absorption.

The first gear 2 and the second gear 4 are fixedly mounted at one end of the zipper tape 100, preferably in the longitudinal direction.

The first gear 2 or the second gear 4 is formed of a metal or plastic material. The mounting process of the first gear 2 or the second gear 4 follows a well-known technique, and a detailed description thereof will be omitted.

In principle, the first gear 2 and the second gear 4 are alternately coupled to each other, but a rectangular plate shape having a larger area is taken as a basic shape so that the displaced shape does not appear as a conventional appearance.

A portion of the square plate of the first gear 2 is cut at right angles so that the first stepped portion 23 is formed. The first engagement portion 25 is formed on one side by forming the first stepped portion 23.

A second stepped portion 43 is formed by cutting at right angles to the opposite side of the second gear 4, but the second stepped portion 43 is formed to have the same depth as the first stepped portion 23. By forming the second stepped portion 43, the second engagement protrusion 45 is formed on one side.

Therefore, the first gear 2 has a substantially 'b' shape, and the second gear has a substantially 'b' shape, and when the first and

second gears

2 and 4 are connected to each other, Appearance can be realized in the form of a rectangular plate.

convex portions

256 and 436 and the

concave portions

257 and 437 may be coupled to each other, thereby preventing a gap between the

convex portions

256 and 437.

On the other hand, one side of the first body 21 is formed by recessing the first step portion 27 in a portion facing diagonally with the first step portion 23.

In addition, the second step portion 47 is formed at one side surface of the second body 41 at a portion facing diagonally to the second step portion 43.

The first and second stepped

portions

27 and 47 may provide a separation space that does not contact the adjacent first gear 2 or the adjacent second gear 4, thereby implementing the bending or opening or closing of the zipper. It provides a minimum separation space that can not be prevented from bending by other adjacent teeth. In addition, it provides a minimum separation space that can smoothly open and close the teeth during the opening or closing operation of the zipper. Will be done. By this minimal space, the bending and opening and closing operation can be performed smoothly.

Alternatively, the first and second stepped

portions

27 and 47 may not be formed. This is because the first and second stepped

portions

27 and 47 are not necessary if they are arranged in such a manner that the interval between the teeth is properly maintained.

Therefore, the first and second stepped

portions

27 and 47 may or may not be formed in view of appearance.

Meanwhile, a fix pin 62 is formed at a lower end of the first tooth part G1, and a mobile pin 64 is formed at a lower end of the second tooth part G2 to form a bottom stop 6. The length of the fix pin 62 and the mobile pin 64 is the same.

The stops (not shown) formed at the upper ends of the first tooth G1 and the second tooth G2 also have the same orthodontic teeth, and the stops are formed in the same way.

The fix pin 62 and the mobile pin 64 are symmetrically formed at the bottom of each zipper tape 100, and are usually made of metal or plastic and mounted to the zipper tape 100 by pressing or the like.

The retainer box 63 is formed at a lower end of the fix pin 62, and a fitting slot is formed at the top and the inside of the retainer box 63 so that the mobile pin 64 may be coupled to the fix pin 62.

Therefore, the mobile pin 64 is inserted into the retainer box 63 to connect the beginning of the zipper. At this time, the ends of the dental teeth are horizontal so that the upper ends of the mobile pin 64 and the fix pin 62 are positioned at the same height. This can be beautiful.

Meanwhile, the first and second tooth parts G1 and G2 include a pattern forming part 8 extending on one side of the first and

second teeth

2 and 4 and formed on the upper surface of the zipper tape 100.

The glyph forming part 8 is formed on one side of the first and

second bodies

21 and 41 of the first and

second gears

2 and 4 but is smaller than the clearance height of the slider 300 so that the slider 300 can pass. And first and second

glyph expressing members

81 and 82 formed to a thickness.

As shown in FIGS. 4 and 6, the first and second

glyph expressing members

81 and 82 are formed to be symmetrical in parallel at the same position on both sides.

Alternatively, as shown in FIGS. 7 to 9, the first and second

glyph display members

81 and 82 may be asymmetrically formed to be offset.
