EMBODIMENT OF THE INVENTION Hereinafter, the Example of this invention is described in detail.

As shown in FIG. 1, the waterproof zipper of the present invention is formed to correspond to each other on the surfaces of the zipper part 10 and the zipper part 10 facing each other, and is coupled to each other, or is separated and coupled forward. The exposed surface includes a rail portion 20 forming the same plane as the front surface of the zipper portion 10. The rail unit 20 is provided with a coupling slider 30 to move or couple the rail unit 20.

The zipper part 10 and the rail part 20 are made by extrusion molding and are integrally formed. Specifically, the rail unit 20 is formed at the end of the zipper unit 10.

The zipper portion 10 is made of polyurethane material. Polyurethane material is waterproof, light and easy to wash.

A straight stripe having peaks and valleys is formed in the zipper 10 in the moving direction of the coupling slider 30. In the present embodiment, the straight stripes are formed in the longitudinal direction, which is the moving direction of the coupling slider, in the entire zipper portion.

The straight stripes create the effect of thinning the basic thickness of the zipper portion 10 to soften the zipper portion 10 itself. In addition, the straight stripes reduce the friction between the rail unit 20 and the coupling slider 30 when the coupling slider 30 moves to facilitate sliding. In addition, the straight stripes increase the adhesiveness of the fabric and the zipper 10 by increasing the permeability of the adhesive when the zipper 10 is bonded to the fabric, such as clothing or bags.

The zipper portion 10 is divided into first and second zipper portions 11 and 13.

As shown in Figures 2 and 3, the first and second zippers (11, 13) are separated by cutting in the longitudinal direction the center of the zipper portion fabric extruded so that the rails 20 are formed at both ends, respectively. It is. This reduces the number of processes of the zipper fabrication and facilitates the fabrication.

The rail portion 20 is composed of first and second rail portions 21 and 23. The first rail part 21 is formed at one side of the first zipper part 11, and the second rail part 23 is formed at one side of the second rail part 23. Specifically, any one of the first and second rail portion (21, 23) is formed on a plane extending from the zipper portion 10, the other one on the plane formed stepped downward from the zipper portion (10) Is formed.

The first and second rail portions 21 and 23 are formed with the engaging protrusions 21a and 23a, the close contact portions 21b and 33b, and the engaging hooks 21c and 23c, respectively. The engaging protrusions 21a and 23a are annular and are formed at both end portions of the zipper 10, and the close contacting portions 21b and 33b are spaced apart from the engaging protrusions 21a and 23a by the inside of the zipper 10. It is formed at a predetermined position and has an inner curved surface corresponding to the engaging protrusions 21a and 23a. The locking hooks 21c and 23c protrude from the locking protrusions 21a and 23a and the close contact portions 21b and 33b.

As shown in FIG. 4, the contacting protrusions 21a formed on the first rail portion 21, the contacting portions 21b, and the contacting portions 23b formed at the second rail portions 23 are provided at the second rail portions 23. The engaging protrusion 23a and the engaging hook 23c are mutually coupled. The front surface exposed to the outside in a state in which the first rail portion 21 is coupled to the second rail portion 23 forms the same plane as the front surface of the zipper portion 10, and the rear surface positioned inside the protrusion protrudes inwardly. Becomes

The combined front surface of the first rail portion 21 and the second rail portion 23 forms the same plane as the front surface of the zipper portion 10 between the first rail portion 21 and the second rail portion 23. This is to minimize the gap between to prevent the infiltration of external moisture and to make it easy to attach to the fabric or sewing.

The annular shape of the engaging protrusions 21a and 23a and the inner curved surfaces of the contacting portions 21b and 23b have the engaging protrusions 21a and 23a when the first rail portion 21 and the second rail portion 23 are coupled to each other. By forming a shape wrapped in the close contact portion (21b, 23b) serves to prevent the opening of the first rail portion 21 and the second rail portion 23 by the external force.

The hook hooks 21c and 23c have a configuration for increasing the coupling force between the first rail portion 21 and the second rail portion 23.

3 and 4, the hook hooks (21c, 23c) is a "T" shaped cross section consisting of a central pillar and both side hook wings, "T" shaped both sides of the hook wing portion of the zipper portion The inward part is long and the outward part is short asymmetric.

The long part of the hook wing S is for increasing the combined tensile force of the first rail part 21 and the second rail part 23, and the short part m of the hook wing S is permeated with external moisture rather than the tensile force. It is to prevent. The long portion (l) of the hook wing (S) is hooked with the ring shape of the locking protrusion to increase the combined tensile force of the first rail portion 21 and the second rail portion (23).

The upper surface of both hook wings (S) is formed in a curved surface. In this way, the portion facing the outer side of the hook wing (S) is shorter than the portion facing the inner side of the hook wing (S) and the upper surface of the hook wing (S) formed in a curved surface to the movement of the coupling slider (30) To facilitate the coupling and separation of the rail unit 20 according to.

If the upper surface of the hook wing (S) is formed in a plane and both sides of the hook wing (S) are formed long, the coupling and separation of the rail unit 20 according to the movement of the coupling slider 30 is not natural.

As shown in Fig. 2 and 3, the first and second rail portions (21, 23) is a locking portion (21a, 23a), the contact portion (21b, 23b), the hook on both ends of the zipper fabric (1) It is preferable that the hooks 21c and 23c are extruded to face in the same direction, which facilitates the storage of the zipper fabric 1 and the zipper fabric 1 when storing the zipper fabric 1 without being separated. Even if the bending occurs in the final zipper product that combines the first rail portion 21 and the second rail portion 23 to achieve a flat surface without bending.

If the first and second rail portions 21 and 23 of the extruded zipper fabric 1 are formed to face in different directions, the warpage of the zipper fabric 1 may be easily generated during storage, and may be separated when the warpage occurs. Since the warpage generation direction of the zipper 10 is the same as each other, the final zipper product is not easily coupled.

On the other hand, if the first and second rail portions 21 and 23 of the extruded zipper fabric 1 are formed in the same direction to each other, even if the warpage of the zipper fabric 1 occurs during storage, they are separated from each other. Since the state is bent in the joining direction, the final zipper product is flat without bending.

On the other hand, the end of the zipper portion 10 is formed with a stopper portion 15 for regulating the movement position of the coupling slider (30). As shown in FIG. 1, the stopper part 15 is formed by pressing the ends of the zipper part 10 coupled to each other. The stopper part 15 may be compressed in a state where the coupling slider 30 is coupled to the zipper 10, or may be compressed in a state before the coupling slider 30 is coupled to the rail part.

The coupling slider 30 is for coupling and detaching the zipper.

As shown in FIG. 5, the coupling slider 30 has two upper and lower insertion holes 31 and 33 formed on the front side, and as shown in FIG. 6, corresponding to opposite sides of the insertion holes 31 and 33. One through hole 35 is formed in communication with the insertion holes 31 and 33 at the rear side, and as shown in FIGS. 5 and 7, the insertion holes 31 and 33 and the through holes ( Guide slits 45 and 47 communicating 35 are formed, respectively.

Insertion holes 31 and 33 are configured to separate the rail portion 20 from the first rail portion 21 and the second rail portion 23 up and down, and the through hole 35 is the first separated up and down. It is a structure for coupling the rail part 21 and the 2nd rail part 23 to one rail part 20. As shown in FIG.

As shown in FIG. 8, the rail unit 20 passes through the insertion holes 31 and 33, the guide slits 45 and 47, and the through hole 35 of the coupling slider 30. The rail part 20 exposed to the front end side or the rear end side and exposed through the insertion holes 31 and 33 is separated into the first rail part 21 and the second rail part 23, and has a through hole ( The rail unit 20 exposed through 35 is in a state in which the first rail unit 21 and the second rail unit 23 are coupled to each other.

That is, when the coupling slider 30 coupled to the rail unit 20 moves to the front side, the two rail units 20 entering the insertion holes 31 and 33 are coupled while passing through the through hole 35 and are connected to one another. When the coupling slider 30 moves to the rear side on the rail unit 20, the rail unit 20 entering the through hole 35 passes through the insertion holes 31 and 33. Rail parts 20 are separated. Here, the front side and the rear side are based on the position of the waterproof zipper shown in FIG. 8, and the front side corresponds to the left side in the drawing, and the rear side corresponds to the right side in the drawing.

As shown in FIG. 7, a guide part 41 is formed inside the coupling slider 30 to separate the insertion holes 31 and 33 into two upper and lower parts. The guide portion 41 is formed in an inclined upward direction toward the insertion hole 31 of the upper front side of the coupling slider 30 in a substantially plate shape. The guide part 41 enters the through hole 35 so that the rail part 20 passing through the insertion holes 31 and 33 is naturally separated into two upper and lower rail parts 20.

In addition, the inner bottom surface 43 of the coupling slider 30 in communication with the lower insertion hole 33 is formed in a plane. The inclined surface of the guide part 41 and the inner plane of the coupling slider 30 allow the rail part 20 to be vertically separated.

Guide slits 45 and 47 are for guiding the zipper 10. As shown in FIGS. 7 and 8, the guide slit 45 communicating the upper insertion hole 31 and the through hole 35 has an inclination corresponding to the guide part 41, and is illustrated in FIG. 5. As described above, the guide slit 47 communicating the lower insertion hole 33 and the through hole 35 is formed in a straight line corresponding to the inner bottom surface 43 of the coupling slider 30.

As shown in FIG. 5, a rail guide 49 is formed on the lower surface of the guide part 41. Rail guide 49 is for facilitating the guide of the rail unit 20 to be separated in the lower portion in the process of separating the rail unit 20 up and down. Rail guide 49 is formed to protrude downward on the lower surface of the guide portion 41, the front and rear portions are formed in a curved shape.

The coupling slider 30 further includes a coupling piece 51 protruded from the front side toward the rear side of the coupling slider 30 so that the end thereof faces the upper surface of the coupling slider 30. The engaging portion 51 is hooked to the handle portion 60 for moving the engaging slider 30 on the rail portion 20.

The pressing portion 53 protrudes from the upper surface of the coupling slider 30 facing the end of the coupling piece 51.

The pressing part 53 has a structure that is elastically moved to the space between the coupling piece 51 and the upper surface of the coupling slider 30 when an external force is applied. The elastic movement of the pressing portion 53 can be implemented by applying elastic means such as a spring. In this embodiment, a spring (not shown) and a pressing part 53 are sequentially assembled to the upper surface of the coupling slider 30.

The handle portion 60 for moving the rail portion 20 of the coupling slider 30 is coupled to the coupling piece 51. Substantially, the hook ring 61 provided on the handle portion 60 is hooked to the coupling piece 51 so that the handle portion 60 is hooked to the coupling slider 30.

The end and the pressing portion of the engaging piece 51 to prevent the hook ring 61 from being arbitrarily detached from the engaging piece 51 while the hook 61 is easily hooked on the engaging piece 51 and is engaged. The spacing between the 53 is narrower than the thickness of the hook ring 61, the spacing between the bottom of the coupling piece 51 and the pressing portion 53 is formed wider than the thickness of the hook ring (61).

Hook ring 61 may be formed integrally with the handle portion 60, or may be manufactured separately and coupled to the handle portion (60). The handle part 60 is easily replaced by the handle part detachably coupled to the coupling piece 51 using the hook ring 61. Accordingly, it is possible to employ various kinds of handles 60 as desired in one coupling slider (30).

The handle portion and the coupling slider may be made of metal.

Hereinafter, a process of manufacturing the waterproof zipper will be described in detail.

In the manufacturing process of the waterproof zipper, first, the polyurethane as a raw material is transferred into the space formed by the upper and lower shape cores of the mold in a molten state, and the upper and lower shape cores cooperate with each other to extrude the zipper fabric 1.

Extruded zipper part fabric (1) is formed at both ends of the rail portion 20, the incision line (t) is formed in the center, a straight stripe is formed in the longitudinal direction. In addition, the rail portions 20 at both ends of the zipper fabric 1 have locking protrusions 21a and 23a, close contact portions 21b and 23b, and locking hooks 21c and 23c formed in the same direction.

Extruded zipper part fabric (1) is dried at room temperature. Here, since the polyurethane used as the raw material of the zipper fabric 1 is glossy, the zipper fabric is made of glossy, so that the waterproof zipper, which is the final product, is attached to various products, to prevent it from being noticed due to the glossy when used. Zipper fabric finished drying at room temperature can be matte.

Thereafter, the central incision line t of the zipper fabric 1 is cut and separated into the first zipper part 11 and the second zipper part 13.

As shown in FIG. 9, the separated first zipper part 11 and the second zipper part 13 are disposed such that the first rail part 21 and the second rail part 23 face each other, and then are coupled to each other. Insert the first rail portion 21 of the first zipper portion 11 into the upper insertion hole of the slider 30 and insert the second rail portion 23 of the second zipper portion 13 into the lower insertion hole. The coupling slider 30 is moved leftward in the drawing so that the first zipper part 11 and the second zipper part 13 simultaneously pass through the through hole 35.

In this process, the first zipper part 11 is guided along the inclined guide slit 45 for communicating the upper insertion hole 31 and the through hole 35 of the coupling slider 30, and the second zipper part ( 13 is guided along the opposite linear guide slit 47 communicating the lower insertion hole 33 and the through hole, so that the first rail part 21 and the second rail part 23 are naturally coupled or separated.

As shown in FIG. 8, when the coupling slider 30 moves forward in the drawing, the first and second rail parts 21 and 23 entering the insertion hole pass through the through hole 35 as shown in FIG. 8. When the coupling slider 30 is moved to the rear side in the drawing, the rail unit 20 entering the through hole 35 passes through the insertion holes 31 and 33. Guided by the 41 and the rail guide 49 is separated up and down into the first rail portion 21 and the second rail portion (23).

When the first rail portion 21 and the second rail portion 23 are coupled to each other, the locking protrusion 21a, the contact portion 21b, and the hooking hook 21c formed on the first rail portion 21 are connected to the second rail. The close contact portion 23b, the locking protrusion 23a, and the locking hook 23c formed on the part 23 are closely coupled to each other, and the front surface exposed to the outside forms the same plane as the front surface of the zipper 10. This structure prevents the ingress of external moisture and makes the appearance beautiful (see FIG. 4).

Next, the end of the zipper 10 coupled to the first rail portion 21 and the second rail portion 23 is compressed to form a stopper portion 15 that regulates the movement position of the coupling slider 30. (See Fig. 1)

When the waterproof zipper is completed by the above-described method, the waterproof zipper may be attached to the fabric by bonding or sewing. In this case, it is easy to attach to the fabric by the straight stripes formed on the waterproof zipper, and the waterproof zipper itself is soft, so the wearability is excellent, and the sliding slider is naturally made.

On the other hand, the handle portion 60 is made separately from the coupling slider 30 and then coupled to the coupling slider 30.

As shown in FIG. 10, the handle 60 is coupled to the coupling slider 30 by pushing the hook 61 of the handle 60 against the pressing part of the coupling slider 30 to the front side. . Then, the pressing portion 53 is pushed to the front side and the hook ring 61 is inserted into the space between the engaging piece 51 and the upper surface of the engaging slider 30, and at the same time the pressing portion 53 is returned to its original position. Hook ring 61 is hooked to the engaging piece (51). This is achieved by returning to the original position by the elastic force of the elastic means after the pressing portion 53 is moved.

When the hook 61 is inserted into the space between the coupling piece 51 and the upper surface of the coupling slider 30, the gap between the end of the coupling piece 51 and the pressing part 53 is hooked 61. Since it is formed to be narrower than the thickness of the handle portion 60 and the combined slider 30 is not released in any state.

In addition, releasing the engagement of the coupling slider 30 and the handle portion 60 by pushing the pressing portion 53 to the front side by using a tool around the space between the bottom of the coupling piece 51 and the pressing portion. The hook ring 61 may be moved to the rear side to be released. In this case, since the space | interval between the bottom face of the engaging piece 51 and the press part 53 is wider than the thickness of the hook ring 61, the back side movement of the hook ring 61 is easy, and it is easy to release | release.

As such, manufacturing the handle 60 and the coupling slider 30 in a detachable manner enables various applications of the coupling slider 30 only by replacing the handle 60.

On the other hand, the manufactured waterproof zipper as shown in Figures 1 and 11, the combined rail portion 20 is arranged to the rear of the zipper portion 10 to beautify the appearance of the front of the zipper portion 10 and waterproof effect Also raises.

The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self evident.
