  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Referring to FIGS. 1 and 2, a zipper in accordance with the present invention is shown comprised of two zipper tapes 1, male teeth elements 2, female teeth elements 3, and a slider body 4.
  • Similar to the conventional designs, the zipper tapes 1 each have a cylindrical flange 11 extending along the length at one side.
  • Referring to FIG. 5 and FIGS. 1 and 2 again, the male teeth elements 2 are arranged in series along one side of one zipper tape 1, each comprising a split tube-like base 22 fastened to the cylindrical flange 11 of the associating zipper tape 1, a hook strip 21 perpendicularly extending from the periphery of the split tube-like base 22, and two clamping strips 23 extending from the split tube-like base 22 and clamped on the top and bottom surface of the associating zipper tape 1 to secure the split tube-like base 22 to the cylindrical flange 11 of the associating zipper tape 1 firmly. The split tube-like base 22 can be made having a hole 221 at one side or each of two opposite sides to enhance engagement between the split tube-like base 22 and the cylindrical flange 11 of the associating zipper tape 1. The hook strip 21 has a bend portion 211 extending from the periphery of the split tube-like base 22, and a hook portion 212 extending from one end of the bend portion 211 remote from the split tube-like base 22.
  • The female teeth elements 3 are arranged in series along one side of the other zipper tape 1 to match the male teeth elements 2, each comprising a split tube-like base 33 fastened to the cylindrical flange 11 of the associating zipper tape 1, a hollow receiving portion 32 protruded from the periphery of the split tube-like base 33 at one side, a hook hole 31 on the outer side of the hollow retaining portion 32, and two clamping strips 34 extending from the split tube-like base 33 and clamped on the top and bottom surface of the associating zipper tape 1 to secure the split tube-like base 33 to the cylindrical flange 11 of the associating zipper tape 1 firmly (the clamping strips 23 or 34 of the male teeth elements 2 or female teeth elements 3 may be eliminated). The split tube-like base 33 can be made having a hole 331 at one side or each of two opposite sides to enhance engagement between the split tube-like base 33 and the cylindrical flange 11 of the associating zipper tape 1.
  • The slider body 4 is movable over the male teeth elements 2 and the female teeth elements 3 to force the male teeth elements 2 into engagement with the female teeth elements 3 or to separate the male teeth elements 2 from the female teeth elements 3, having a guide groove 41 (see FIG. 2) for guiding the hook strip 21 of each male teeth element 2 into the hook hole 31 of the respective female teeth element 3. Further, a pull-tab 42 is coupled to the slider body 4.
  • Referring to FIGS. 3 and 4, when pulling the slider body 4 in one direction, the hook strips 21 of the male teeth elements 2 are respectively guided into the hook holes 31 of the female teeth elements 3 and kept engaged in the receiving portions 32 of the female teeth elements 3. On the contrary, when pulling the slider body 4 in the reversed directions, the hook strips 21 of the male teeth elements 2 are respectively forced away from the hook holes 31 of the female teeth elements 3.
  • Referring to FIGS. 6 and 7, the guide groove 41 of the slider body 4 is adapted for the passing of the hook strip 21 of each male teeth element 2 when the slider body 4 is moving over the male teeth elements 2 and the female teeth elements 3 and for guiding the hook strip 21 of each male teeth element 2 toward a predetermined direction so that the hook strips 21 of the male teeth elements 2 can be respectively and accurately forced into the hook holes 31 of the female teeth elements 3 and kept in positive engagement with the receiving portions 32 of the female teeth elements 3.
  • Referring to FIGS. 8 and 9, the invention can be made in the form of a close end zipper (see FIG. 8) or open end zipper (see FIG. 9).
  • In the aforesaid embodiment (see FIGS. 1˜9), the male teeth elements 2 and the female teeth elements 3 are independent elements and separately fastened to the associating zipper tapes 1. As an alternate form of the present invention, the male teeth elements 2 and the female teeth elements 3 can be separately formed in integrity, i.e., the clamping strips 23 a or 34 a of the teeth elements 2 or 3 at the same side are formed integral with one another. Therefore, the teeth elements 2 or 3 can be independent elements and separately fastened to the zipper tapes 1, or made in one single piece and directly fastened to one zipper tape 1.
  • According to the present invention, the male teeth elements 2 and the female teeth elements 3 can be made of metal by means of metal stamping. When the metal male teeth elements 2 and the metal female teeth elements 3 are fastened to the zipper tapes 1 to form a metal zipper, the metal zipper shows a sense of ancient style.
  • In case a metal material is used for making the male teeth elements 2 and the female teeth elements 3, the male teeth elements 2 and the female teeth elements 3 can be respectively stamped from a single metal sheet member. After stamping, the hook strips 21 of the male teeth elements 2 are bent into shape (see FIG. 5). Except the hook strips 21, the split tube-like bases 22 (33), the clamping strips 23 (34), the holes 221 (331), the hook shape of the hook strips 21 of the male teeth elements 2 and the hook holes 31 and hollow receiving portions 32 of the female teeth elements 3 are all formed by means of stamping. Therefore, the fabrication of the male teeth elements 2 and the female teeth elements 3 is easy and quick. After fabrication, the male teeth elements 2 and the female teeth elements 3 can be fastened to the cylindrical flanges 11 of the zipper tapes 1 quickly and tightly. Therefore, the invention is suitable for mass production.
  • The receiving portions 32 of the female teeth elements 3 cover the periphery of the cylindrical flange 11 of the associating zipper tape 1 such that the receiving portions 31 of the female teeth elements 3 are kept in an enclosed status relative to the cylindrical flange of the cylindrical flange 11 of the associating zipper tape 1 and the cylindrical flange 11 of the associating zipper tape 1 will never enter the receiving portions 31 of the female teeth elements 3 when the male teeth elements 2 and the female teeth elements 3 are stretched heavily.
  • Further, the zipper may be variously embodied without departing from the spirit and scope of the invention. FIGS. 10˜12 show an alternate form of the zipper according to the present invention. According to this embodiment, the aforesaid clamping strips 23 and 34 are respectively eliminated from the male teeth elements 2 and the female teeth elements 3, and the split tube- like bases 22 and 33 are directly fastened to the cylindrical flanges 11 of the zipper tapes 1.
  • According to the aforesaid embodiments, the male teeth elements 2 and the female teeth elements 3 are fastened to the zipper tapes 1 by means of the split tube- like bases 22 and 33, or clamping strips 23 and 34.
  • According to another alternate form of the present invention, as shown in FIGS. 13 and 14, the clamping strips 23 and 34 of the male teeth elements 2 and the female teeth elements 3 each have a plurality of spurs 24 or 35 at an inner side for engaging into the zipper tapes 1 to affix the male teeth elements 2 and the female teeth elements 3 to the associating zipper tapes 1 (see FIGS. 15˜18). The spurts 24 of the two clamping strips 23 of each male teeth element 2 are arranged in a staggered manner.
