Definitions

  • the present invention relates to slide fasteners, and more particularly to a watertight slide fastener stringer.
  • Watertight slide fastener stringers which generally comprise a single support tape made of a water-tight soft material, and a row of discrete coupling elements mounted on the tape along an inner longitudinal edge portion thereof; such tape margin is folded so as to provide therealong a contact portion engageable with a corresponding contact portions of a like companion stringer to effect a watertightness between the two stringers.
  • the opposed coupling element rows of the two stringers are interengaged by a slider to close the watertight slide fastener, the opposed contact portions are brought into contact with one another.
  • a watertight slide fastener stringer (20) comprising: a support tape (7) made of a water- tight soft material and having a first folded edge portion (7a) and a first contact portion (7b) contiguous thereto and engageable with a corresponding first contact portion (7'b) of a support tape (7') of a like companion stringer (20') to effect a watertightness between such two support tapes (7, 7'), characterised in that the slide fastener comprises further an auxiliary tape (8) made of a watertight soft material and having a second folded edge portion (8a) spaced apart facewise from said first folded edge portion (7a), and a second contact portion (8b) laterally spaced apart from said first contact portion (7b) and engageable with a corresponding second contact portion (8'b) of an auxiliary tape (8') of the companion stringer (20') to effect a watertightness between such two auxiliary tapes (8, 8'); and a row of discrete coupling elements (1) mounted on and
  • the present invention seeks to provide a watertight slide fastener stringer which enables efficient and reliable watertightness between the opposed companion stringers.
  • the present invention further seeks to a watertight slide fastener stringer which enables smooth movement of a slider.
  • stringer watertight slide fastener stringer
  • Figures 2 and 3 generally indicated by the numeral 20.
  • the stringer 20 includes a support tape 7 made of a watertight soft material such as natural or synthetic rubber, or made of natural or synthetic fibers coated with such a watertight material.
  • the tape 7 has an inner longitudinal margin folded through its whole length so as to provide a first folded edge portion 7a and a first contact portion 7b contiguous thereto.
  • the first and second folded edge portions 7a, 8a are spaced apart facewise from one another, while the first and second contact portions 7b, 8b are laterally (vertically in Figure 3) spaced apart from one another.
  • the auxiliary tape 8 may be an integral part of the support tape 7.
  • the first and second contact portions 7a, 8a are adapted to engage corresponding first and second contact portions 7'a, 8'a, respectively, of a like companion stringer 20' ( Figures 4 and 5), to effect a watertightness between the two stringers 20, 20'.
  • a first core thread 9 coextends lengthwise with the support tape 7 and is attached to the first folded edge portion 7a.
  • a second core thread 10 coextends lengthwise with the auxiliary tape 8 and is attached to the second folded edge portion 8a.
  • a row of discrete coupling elements 1 is mounted on and along the first and second folded edge portions 7a, 8a of the tapes 7, 8; each coupling element 1 has a base 2, a neck 6, a coupling head 5, and first and second legs 3a, 3b.
  • the base 2 is disposed remotely from and parallel to the first and second contact portion 7b, 8b.
  • the neck 6 extends centrally from the base 2 and is disposed between the first and second folded edge portions 7a, 8a.
  • the coupling head 5, in the form of an enlarged portion, extends from the neck 6 beyond the first and second contact portions 7b, 8b.
  • the first and second legs 3a, 3b extend from opposite ends of the base 2 in the same direction as the neck 6 so as to hold tightly the first and second folded edge portions 7a, 8a between the first leg 3a and the neck 6 and between the latter and the second leg 3b, respectively.
  • the first and second legs 3a, 3b terminate in first and second flanges 4a, 4b, respectively, disposed on the respective back surfaces of the first and second contact portions 7b, 8b.
  • Each of the first and second flanges 4a, 4b has inner or outer sections projecting in opposite directions from a respective one of the first and second legs 3a, 3b.
  • the first and second core threads 9, 10 are disposed between the inner section of the first flange 4a and the base 2 and between the inner section of the second flange 4b and the base 2, respectively.
  • the inner flange sections serve to assist in holding the folded edge portions and the core threads in place between the neck 6 and the legs 3a, 3b.
  • the outer flange sections serve as guide rails for a slider 11 ( Figure 5).
  • the slider 11 has in its inner wall 12 a longitudinal groove 13 for the passage therethrough of the outer sections of the second flanges 4b, 4'b and the outer halves of the second contact portions 8b, 8'b.
  • Another advantage of the watertight stringer 20 is that during interengagement of the opposed companion stringers 20, 20', the slider 11 is guided by the first flanges 4a, 4'a and also by the second flanges 4b, 4'b, thus guaranteeing smooth movement of the slider. Further, since the slider 11 does not touch either the support tape 7 or the auxiliary tape 8 during movement along the opposed coupling element rows 1,1', these tapes 7, 8 are free from being easily worn or otherwise damaged, thus guaranteeing reliable slide- fastener functions and efficient water-tightness for a long period of time.
