Definitions

  • the invention relates to a zipper, with two rows of coupling members, which are fastened by means of fastening elements to two support bands, which have sealing tabs, the coupling members being in engagement in the closed position and the sealing tabs being pressed against one another in a sealing manner, the fastening members being outside the plane of the two Carrying tapes lie.
  • Such a known zipper should be as gastight and watertight as possible due to its sealing tabs.
  • a zipper is known for example from CH-PS 197 259, 419 693, 433 838 as well as from EU-A3-73018 and from GB patent application 2 158 506A. If these known zippers are put under tension by pulling the two straps of the zipper apart, the pressure on the sealing tabs is relieved and a gap can occur between them, so that the zipper is no longer gas and water tight. In order to remedy this, a zipper has already been proposed (CH-350 266), in which two sealing straps are pressed together by pulling the two straps apart to maintain the tightness of the zipper as much as possible.
  • the aim is to create a zipper in which the aforementioned disadvantages can be avoided.
  • the zipper according to the invention is characterized in that the coupling members are provided with support shoulders for mutual positive engagement when the coupling members pivot about their fastening members transversely to the plane of the carrying tapes, and that the support shoulders are occupied by the sealing tabs.
  • the coupling members are designed as teeth 1 and 2.
  • the fasteners are available as cords 3 and 4.
  • the coupling links 1 and 2 are thus fastened to two carrying straps 5 and 6 by means of the cords 3 and 4.
  • the coupling members 1 and 2 of the two rows 7 and 8 are in engagement with each other.
  • Each coupling member 1 is provided with a support shoulder 9, and each coupling member 2 is provided with a support shoulder 10.
  • the support shoulder 9 has a first support surface 11, and the support shoulder 10 has a first support surface 12.
  • the first support surfaces 11 and 12 are inclined to the plane of the carrier tapes 5, 6.
  • the support shoulders 9 and 10 also have second support surfaces 13 and 14, which are inclined to the first support surfaces 11 and 12.
  • the first and second support surfaces are at right angles to one another, in the example according to FIG. 3 they are inclined at an angle other than 90 °.
  • the fastening elements 3 and 4 lie outside the plane of the two carrying bands 5 and 6, with a distance 15 being present.
  • the two support shoulders 9 and 10 engage positively behind one another, with an overlap dimension 16 being present.
  • the first free end 21 and the second free end 22 of the strap 5 integral with the sealing tab 19 can be seen.
  • the carrier tape 6, which is integral with the sealing tab 20, likewise has a first free end 23 and a second free end 24.
  • the other free end 22 of the carrier tape 5 is parallel to its first free end 21.
  • the free end 24 lies at a parallel distance from the first free end 23.
  • its sealing tab 19 lies between the two free ends 21 and 22 of the carrier tape 5.
  • Between the two free ends 23 and 24 of the carrier tape 6 is its sealing tab 20. From FIG. 3 it can also be seen that the sealing tab 19 is inclined to the two free ends 21 and 22 of the supporting tape 5, at an angle other than 90 ° . To the same extent, the sealing tab 20 is inclined to the two free ends 23 and 24 of the carrier tape 6.
  • a chamber 25 which connects the two carrying bands 5 and 6 and which is forked so that the heart 26 of the slide 27 can be moved as far up as possible in FIG.
  • the uppermost coupling members of the zipper are in engagement with one another and press the sealing tabs 19 and 20 shown in FIG. 3 in a sealing manner.
  • Below the clamp 25 there are also two run-up ramps 28 and 29, which serve to open the heart 26 to open the zipper.
  • each coupling member 1 has two support shoulders 31 for the head parts 32 of the adjacent coupling members 2 in the region of its neck-like constriction 30 (FIG. 2).
  • the head part 32 can then be supported with its two lower surfaces 33 on these support shoulders 31 if the two carrying bands 5 and 6 are pulled apart according to FIG. 1.
  • the same is present with each coupling member 2; thus the support shoulders 34 for the adjacent coupling members 1 with their lower surfaces 35.
