Description
FIELD OF THE INVENTION

The present invention relates to a zipper assembly having a separable slider, particularly a zipper assembly having a separable slider that makes it possible to simplify the manufacturing process by using a separable slider having the function of a pin box when manufacturing a zipper assembly, and to make various zipper products by applying a separable slider to zipper assemblies in open-end type and closed-end type of one-way types or two-way types.


DESCRIPTION OF THE RELATED ART

In general, zippers that are designed to engage or separate sets of teeth, which are formed by injection molding along one edge of a pair of zipper tapes with a predetermined length, respectively, by reciprocating a slider in which the zipper tapes are fitted at both sides, are used at present in various ways for various clothes, bags, and shoes.


Such zippers are classified into an open-end type of one-way zipper in which the ends of two zipper tapes are separated at the lower end, such as the zippers that are used on the front side of jumpers, a closed-type of one-way zipper in which the ends of two zipper tapes are closed, and a two-way zipper having two sliders to open/close two zipper tapes in two ways.


Further, the zippers fall into a zipper for the right-handed people who operate the pin with the right hand and a zipper for the left-handed people who operate the pin with the left hand, depending on the position of the pin and the pin box.



FIG. 1 illustrates an open-end type of one-way zipper in zipper assemblies of the related art, where zipper teeth 12 and 12′ are formed on the inner ends of two opposite zipper tapes 10 and 10′, respectively, and a pin 18 and a pin box 1 are formed at the lower end of each of the zipper tapes 10 and 10′.


A film 14 having prominences and depressions on the surface of a tape is attached to the lower end portions of the zipper tapes 10 and 10′ where the pin box 1 and the pin 18 are disposed to allow a user to easily insert the pin 18 into the pin box 1 without sliding by giving rigidity.


A slider 50 is disposed between the two zipper tapes 10 and 10′ to fit together or separate the zipper teeth 12 and 12′ and a stopper 16 is disposed at the upper end of each of the zipper tapes 10 and 10′ to prevent the slider 50 from further moving.


Therefore, in order to fasten the two zipper tapes 10 and 10′, a user moves down the slider 50 as low as possible to the pin box 1, inserts the pin 18 into both of the slider 50 and the pin box 1 with the film 14 held, and then holds and moves up the pull tab 51 of the slider 50, thereby fastening the zipper teeth 12 and 12′.


On the other hand, the zippers could be made in an automatic type and a manual type in the related art. For the automatic type, mass production is possible, but the product quality is not uniform, such as that the zipper teeth are opened or a defect of poor fastening of integral pin box and pin, such that expensive zippers are manufactured in the manual type to maintain uniform product quality.


That is, when a zipper is manufactured in a manual type in the related art, as illustrated in FIGS. 2 to 4, zipper teeth are removed at regular intervals from the zipper tapes 10 and 10′ with the zipper teeth 12 and 12′ fitting together, and then the film 14 is attached to the sections with the zipper teeth removed.


Thereafter, through-holes are formed at the portions with the films 14 on the zipper tapes 10 and 10′ by T-cutting, the stoppers 16 are disposed at the upper ends of the zipper tapes 10 and 10′, and then the pin box 1 and the pins 18 are disposed at the lower ends.


Further, it is necessary to fit a side of the slider 50 on the zipper teeth 12 and 12′ of the zipper tapes 10 and 10′ with the pin box 1 and then move down the slider 50, to insert the pins 18 into the slider 50 and the pin box 1, to move up the slider 50 to the upper end of the zipper tape 10, and then to finally cut the zipper tape, such that the process of manufacturing the zipper is complicated and the work efficiency decreases.


Further, when the integral type of pin box 1 is made of plastic and used, the pin box 1 is easily damaged or broken by a small external shock because the pin box 1 is empty, such that using zipper is inconvenient and the life span is decreased.


Further, when the pin box 1 made of metal integrally with the pins 18 is caulked, as illustrated in the enlarged view of FIG. 4, the front and back may be different, such that the aesthetic impression of the appearance.


In addition, since the integral type of plastic pin box 1 is not plated, the logos or trademarks of the manufacturer cannot be shown, such that it is difficult to preclude distribution of imitations. Further, even if the integral type of pin box 1 is made of a material that allows showing the logos or the trademarks of manufacturers, only one side of the pin box can be used, such that many molds are needed; therefore, there is a problem in that the manufacturing cost of the pin box is too high.


As described above, since there are several problems described above in the common pin boxes that are used for zippers, it has been required to develop a new structure that can replace the pin boxes of the related art by removing the problems and can be widely and variously used when manufacturing open-end type and closed-end type of one-way or two-way zipper.
