Description:
FIELD OF THE INVENTION 
       [0001]    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 
       [0002]    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. 
         [0003]    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. 
         [0004]    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. 
         [0005]      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 ′. 
         [0006]    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. 
         [0007]    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. 
         [0008]    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 ′. 
         [0009]    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. 
         [0010]    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. 
         [0011]    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. 
         [0012]    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. 
         [0013]    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. 
         [0014]    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. 
         [0015]    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. 
         [0016]    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.

         [0081]    The fixed member  20  has an extender  24  that is integrally formed with a film  14  and any one of a pair of vertical portions and extends at a predetermined length from the upper end of any one of the pair of vertical portions. 
         [0082]    A connecting portion  25  that integrally connects the lower ends of the pair of opposite vertical portions is provided and an insertion-fixing portion  22  protrudes on the inner sides of the pair of vertical portions  21  and the connecting portion  25 . 
         [0083]    The movable member  30  has an upper plate  32  and a lower plate  34 , similar to the first and second exemplary embodiment, and the portion between the upper plate  32  and the lower plate  34  is supported by the vertical supports  38  with a predetermined distance maintained such that the zipper teeth  12  and  12 ′ can freely pass through between the upper plate  32  and the lower plate  34 . 
         [0084]    Vertical guide portions  44  each having a guide groove  42 , where the zipper teeth  12  and  12 ′ of the pair of zipper tapes  10  and  10 ′ are inserted and that guides movement of the movable member  30 , are bent to be opposite each other at both ends of the upper plate  32  and the lower plate  34 . 
         [0085]    Stepped grooves  46  lower than the tops and the bottoms of the vertical guide portions  44  are formed opposite each other to open downward at an angle, on the tops and the bottoms of the vertical guide portions  44  of the upper plate  32  and the lower plate in order to fit together or open the pair of zipper teeth  12  and  12 ′ when the movable member  30  is moved. 
         [0086]    Accordingly, in the zipper assembly  100   b  of the third exemplary embodiment, similar to the first and second exemplary embodiments, the movable member  30  is inserted and fixed in between the pair of vertical portions  21  of the fixed member  20  to fit together the zipper teeth  12  and  12 ′ of the opposite zipper tapes  10  and  10 ′ by using the slider  50 . 
         [0087]    The pin  18  is inserted along one of the guide grooves of the movable member  30  with the lower end corresponding to or in contact with the upper end of the vertical portion without the extender  24  in the pair of vertical portions such that the pair of zipper teeth  12  and  12 ′ face each other one-to-one, and the pair of zipper teeth that have been open are fitted together by sliding up the slider  50 . 
         [0088]    Compared with the first and second exemplary embodiments, the stepped portions  24   a  and the fixing protrusions  26  and  26   a  are not formed at the fixing member  20  of the separable slider  103  according to the third exemplary embodiment, and the fixing grooves  40  are not formed on the inner sides of the upper plate  32  that is a rectangular plate and the lower plate  34  that is an inverted T-shaped or rectangular plate in the movable member  30 . 
         [0089]    Therefore, since the two-way type of zipper assembly  100   b  includes two movable members  30  and two sliders  50  that is members sliding to open/close the zipper tapes  10  and  10 ′ in two directions, and the fixed member  20  and the movable member  30  without the guide steps  24   a , fixing protrusions  26  and  26   a , and the fixing grooves  40  are manufactured such that the movable member  30  can slide to smoothly open/close the zipper tapes  10  and  10 ′ from the fixed member  20  together with the slider  50 , the present invention can be applied to the two-way type of zipper assembly  100   b  and a zipper assembly can be manufactured in the same way as those of the first and second exemplary embodiments. 
         [0090]    As illustrated in  FIGS. 5 to 10  for the exemplary embodiments of the present invention configured as described above, the processes of manufacturing the zipper assemblies  100 ,  100   a , and  100   b  with the separable sliders  101 ,  102 , and  103  having the function of a pin box are as follows. 
         [0091]    First, as illustrated in  FIG. 11A , the zipper teeth  12  and  12 ′ are removed at regular intervals from the zipper tapes  10  and  10 ′ with the opposite zipper teeth  12  and  12 ′ fitting together by a tooth-installing/removing device (not shown), and then a film  14  is attached to both sides of the zipper tapes  10  and  10 ′ with the zipper teeth  12  and  12 ′ removed, by a film bonding device (not shown). 
         [0092]    Subsequently, through holes  19  are formed at the films  14  attached to the zipper tapes  10  and  10 ′ by T-shape cutting by a cutter (not shown) as illustrated in  FIG. 11B , both ends of the zipper teeth  12  and  12 ′ of the pair of zipper tapes  10  and  10 ′ are partially opened, the movable member  30  of the separable slider is fitted on the zipper teeth  12  and  12 ′ to be temporarily assembled at the lower ends of the zipper tapes  10  and  10 ′, and the slider  50  is fitted on the zipper teeth  12  and  12 ′ to be temporarily assembled at the upper ends of the zipper tapes  10  and  10 ′. 
         [0093]    Further, with the slider  50  and the movable member  30 , which can slide along the zipper teeth  12  and  12 ′, inserted, as illustrated in  FIG. 11   c , stoppers  16  and  16 ′ preventing the slider from being separated are injection-molded at the upper ends of the zipper teeth  12  and  12 ′ that are in contact with the through-holes  19 , by putting the zipper tapes  10  and  10 ′ into an injection molding machine (not shown), and the pins  18  are injection-molded simultaneously with the fixed member  20  that is combined with the movable member, at the lower end. 
         [0094]    Thereafter, the movable member  30  is inserted and fixed in between the pair of vertical portions  21  formed at the fixed member  20  by pulling down the slider  50  or the movable member  30  to the fixed member  20 . 
         [0095]    Further, when the slider  50  that has moved down is pulled up and then the T-shaped through-hole  19  formed through the film is finally cut, the zipper assembly with the zipper teeth  12  and  12 ′ of the pair of zipper tapes  10  and  1 ′ fitting together and the movable member  30  inserted in the fixed member  20  can be easily simply manufactured. 
         [0096]    When the movable member  30  is moved to the fixed member  20  along the zipper teeth  12  and  12 ′ of the pair of zipper tapes  10  and  10 ′ in order to slide down the movable member  30  to be inserted and fixed in the fixed member  20 , the zipper teeth  12  and  12 ′ come closer to each other at the wide portion, which is open at an angle toward the lower ends of the stepped grooves  46  opening downward at an angle, opposite each other at the tops and the bottoms of the vertical guide portions  44  of the upper plate  32  and the lower plate  34  of the movable member  30 , while passing the guide grooves  42  of the vertical guide portions  44  formed opposite each other on both of the upper plate  32  and the lower plate  34  of the movable member  30 , such that the zipper teeth  12  and  12 ′ fit together at the upper end of the guide groove  42 . 
         [0097]    In contrast, when the movable member  30  is slid up in the opposite direction, the zipper teeth  12  and  12 ′ are separated from each other. 
         [0098]    Further, when the movable member  30  is inserted in the fixed member  30 , the stepped grooves  46  of the movable member  30  are guided along the extender  24  extending from one side of the fixed member  20 , and when the guide step  24   a  protrudes on the surface of the extender, it come in close contact with the inner sides of the upper plate  32  and the lower plate  34  of the movable member  30  while moving over the guide step  24   a , and the fixing protrusions  26  and  26   a  of the fixed member  20  are inserted into the opposite fixing grooves  40  formed on the inner sides of the upper plate  32  and the lower plate  34 , such that the movable member  30  can be inserted and firmly fixed in contact with the fixed member  20 . 
         [0099]    Therefore, the separable sliders  101 ,  102  and  103  according to exemplary embodiments of the present invention can be assembled with the inside fully filled in a firm state, not empty, unlike the integral type of pin box of the related art, such that it is possible to prevent the pin box from being damaged or broken by an external shock and to improve the lifespan. 
         [0100]    Further, the movable member  30  of the separable slider according to an exemplary embodiment of the present invention does not need pressing for fixing the movable member to the injection-molded pin when the zipper assembly is manufactured, and the entire of both sides can be used, so that it is possible to improve aesthetic external appearance of the pin box, and when the movable member is made of metal, that is, zinc, it can be plated, such that the logo of the manufacturer can be easily displayed; therefore, it is possible to effective preclude distribution of imitations of expensive bags in the market.
