Description

Double zipper

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a zipper in which teeth are engaged and disengaged according to a moving direction of a slider, and more particularly, to a double zipper in which teeth coupled to a zipper tape are arranged in a double manner to improve a binding force and a shielding force.

As is well known, various types of zippers are used to lock openings in jumper or suit pants, backpacks, bags, sneakers, boots, and the like. The zipper was developed in order to reduce the inconvenience of tying the strings every time it is used. The basic principle is that when the teeth of the zipper are pulled by the jaws arranged in line on the cloth tape, the teeth are engaged with each other to close the opening, When it goes down, the openings are opened as the teeth that are engaged are separated.

There are two types of zippers: a zipper on the outside, a concealed fastener hidden in the seam, and an open fastener. In addition, A giant zipper with stones or stones, a waterproof flat zipper, and a safety zipper that moves the zipper when the zipper ring is lifted.

Hereinafter, a conventional zipper will be described in detail with reference to FIG.

Fig. 1 is a conventional zipper perspective view, and Fig. 2 is a conventional zipper sectional view.

As shown in Figs. 1 and 2, the zipper is generally arranged in such a manner that a pair of zipper tapes 20 composed of a fabric material are opposed to each other. Each of the zipper tapes 20 has a predetermined Teeth 22 of tooth structure having the arrangement interval are continuously connected. A slider 10 having a handle 14 is coupled to the upper side of the line of the teeth 22 so that the pair of teeth 22 are engaged with each other in accordance with the forward and backward movements of the slider 10 And the opening is opened and closed.

1, when the knob 14 is held and the slider 10 is moved forward, a pair of teeth 22 positioned in front of the slider 10 are separated from each other, When the slider 10 is moved backward, the teeth 22 are separated from each other while passing through the body 12 of the slider 10.

However, in the conventional zipper having such a structure, when the zipper is sealed, the contents inserted into the zipper are so tight that they lock tightly, the zipper tape in the opened state is pressed with both hands and the slider is raised. The force is released and the engagement of the teeth is released by the pressure of the contents, and the zipper is opened, so that the contents are protruded out or the zipper can not be used again.

In addition, in the conventional zipper, when a tool end such as a ballpoint pen or a pincer is pressed between a pair of mutually coupled teeth 22, there is a problem that the engagement between the mutually coupled teeth 22 is released and spread.

In addition, since the conventional zipper is divided into a top surface and a bottom surface, the top and bottom of the zipper must be mounted separately when they are coupled to a bag or a garment. There is a problem that it must be judged and discarded.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, an embodiment of a double zipper according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a perspective view of a double zipper according to the present invention, and FIG. 4 is a sectional view of a double zipper according to the present invention.

The first feature of the double zipper according to the present invention is that the teeth are made of two layers so that the teeth can not be disengaged even if they are pressed by a pointed tool such as a ballpoint pen or an auger.

That is, the double zipper according to the present invention includes a pair of zipper tapes 100 arranged in parallel, and a pair of upper teeth 200 (see FIG. 1) disposed on the upper surface of the pair of zipper tapes 100, A pair of lower teeth 300 disposed to face each other on the bottom surface of the pair of zipper tapes 100 and a pair of lower teeth 300 arranged to face the upper teeth 200 and the lower teeth 300, (400).

The pair of upper teeth 200 and the pair of lower teeth 300 are passed through the slider 400 so that the pair of zipper tapes 100 can be transported in the longitudinal direction of the zipper tape 100. [ ). Therefore, when the user grips the handle 410 mounted on the slider 400 with his or her hand and transfers it to one side along the longitudinal direction of the zipper tape 100 (forward side in FIG. 3), the pair of upper teeth 200, Are engaged with each other and the pair of lower teeth 300 are interlocked with each other. On the contrary, when the user holds the handle 410 by hand and transfers the handle 410 to the other side (the rear side in FIG. 3) along the longitudinal direction of the zipper tape 100, the engagement of the pair of upper teeth 200 is released, The lower tooth 300 of the pair is disengaged.

As the slider 400 is transferred along the longitudinal direction of the zipper tape 100, the operation principle of engaging or disengaging the pair of upper teeth 200 with the pair of lower teeth 300 is as follows: As the slider 400 is transferred along the longitudinal direction of the zipper tape 100, a pair of upper teeth 200 and a pair of lower teeth 300 are engaged with each other A detailed description of the process of releasing the engagement is omitted.

As described above, in the double zipper according to the present invention, one zipper tape 100 is provided with two teeth, that is, an upper tooth 200 and a lower tooth 300, respectively, and the pair of upper teeth 200 And when the pair of lower teeth 300 are coupled, the teeth are configured to form two layers. Accordingly, even if a pair of teeth are mutually coupled and a pair of lower teeth 300 are coupled to each other, even if a ball pen or an auger is strongly pressed between the pair of upper teeth 200, the pressing force is lowered to the lower teeth 300 If not delivered, the zipper will not open.

In addition, since the teeth connecting the pair of zipper tapes 100 are formed in two layers, the coupling force is doubled, the blocking force between the zipper tapes 100 is doubled, and the durability is doubled have.

5 and 6 are sectional views showing a pair of zipper tape 100 coupling structures.

The double zipper according to the present invention is characterized in that the shielding force between the pair of zipper tapes 100 when the pair of upper teeth 200 are engaged with each other and the pair of lower teeth 300 are engaged with each other The pair of zipper tapes 100 may be arranged so that one end in the width direction is in contact as shown in Fig.

When the pair of zipper tapes 100 are brought into contact with each other, it is possible to prevent foreign substances such as dust and rainwater from entering between the pair of zipper tapes 100. In addition, when the double zipper according to the present invention is applied to a tent or the like, there is an advantage that the noise blocking effect is enhanced.

The double zipper according to the present invention is characterized in that the pair of upper teeth 200 are mutually engaged and the pair of lower teeth 300 are mutually engaged with each other so that the shielding force between the pair of zipper tapes 100 can be further increased. 6, the pair of zipper tapes 100 may be arranged so that one side in the width direction overlaps the other.

At this time, if the thickness of both sides of the zipper tape 100 is the same, there is a problem that when the pair of zipper tapes 100 are overlapped, the thickness of the corresponding portion becomes thick. Therefore, it is preferable that the overlapping portions of the zipper tapes 100 are made thin as shown in FIG. The width direction of the zipper tape 100 may be a step or a monolayer so as to maximize the adhesion of the zipper tape 100 to each other.

Further, silicon (not shown) may be thinly coated on mutually overlapping surfaces of the pair of zipper tapes 100 so as to maximize the shielding force between the pair of zipper tapes 100. [ As shown in FIG. 6, when the overlapping surfaces of the pair of zipper tapes 100 are coated with silicone, it is possible to more effectively prevent the inflow of dust or rainwater when the one side in the width direction of the zipper tape 100 is laminated .

7 is a sectional view of a double zipper according to a second embodiment of the present invention.

Generally, the teeth to be applied to the zipper are made of plastic or metal. When the teeth are made of plastic, they can be coupled to the upper side and the lower side of one zipper tape 100 as shown in Figs. 3 to 6, respectively.

However, when the teeth are made of metal, the teeth are coupled so as to surround one side in the width direction of the zipper tape 100, so that the upper teeth 200 and the lower teeth 300 are coupled to one zipper tape 100 Can not be.

Therefore, the double zipper according to the present invention is constituted by the upper tape 110 and the lower tape 120 in which the zipper tape 100 is coupled in a laminated structure, And the lower teeth 300 may be coupled to one end of the lower tape 120 in the width direction.

At this time, the portions where the upper teeth 110 and the lower tapes 120 are coupled with the upper teeth 200 and the lower teeth 300 are spaced apart from each other, and the remaining portions are to be coupled in a laminated structure.

When the zipper tape 100 is divided into the upper tape 110 and the lower tape 120 as described above, the teeth can be formed in two layers irrespective of the coupling structure of the upper teeth 200 and the lower teeth 300 In addition, there is an advantage that the coupling of the upper teeth 200 and the lower teeth 300 can be facilitated.

8 is a sectional view of a double zipper according to a third embodiment of the present invention.

As described above, when the zipper tape 100 is composed of the upper tape 110 and the lower tape 120, the upper teeth 200 and the lower teeth 300 may be damaged by contact with each other and noise may be generated have. The double zipper according to the present invention is provided with a separating tape 130 inserted between the upper tape 110 and the lower tape 120 so as to prevent contact between the upper teeth 200 and the lower teeth 300 As shown in FIG.

8, if the isolation tape 130 is additionally provided between the upper tape 110 and the lower tape 120, since the upper teeth 200 and the lower teeth 300 are not in direct contact with each other, It is possible to prevent noise generated due to friction between the upper teeth 200 and the lower teeth 300 as well as damage to the lower teeth 200 and the lower teeth 300.

Also, there is an advantage that the double zipper according to the present invention can be manufactured by utilizing two conventional zipper tapes 20 shown in Fig. The addition of the insulating tape 130 between the upper tape 110 and the lower tape 120 can also be expected to significantly improve the shielding force between the two zipper tapes 100.

At this time, the pair of isolation tapes 130 may be arranged so that one end in the width direction is in contact with the other, or one side in the width direction is overlapped. The arrangement structure of the pair of the isolation tapes 130 is substantially the same as the arrangement structure of the zipper tape 100 shown in FIGS. 5 and 6, and thus a detailed description thereof will be omitted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It will also be appreciated that many modifications and variations will be apparent to those skilled in the art without departing from the scope of the present invention.
