Definitions

  • the present invention relates to a watertight zip fastener with barrier effect, particularly suitable for civilian and military uses, principally in those cases where specific high characterstics of resistance to highly aggressive chemical pollutants are required.
  • the invention sets out to improve the watertight zip fastener of European patent EP 933036 in the name of the same applicant.
  • the zip fastener forming the subject matter of the cited document comprises a profile of elastic material produced by means fo a single extrusion operation, forming two half- chains each consisting of a double-lipped seal having a substantially U-shaped section, the base of which consists of an alveolar rib in which cavities are formed to house the teeth of engagement elements that can be brought into mutual engagement by means of a suitable slider which tends to bring the two half-chains together, placing them in mutual forced opposition.
  • the thickness of the sealing profiles is in the order of a few millimetres
  • the thickness of the fixing tape is normally less than one millimetre. Therefore, a given elastomer material may prove sufficient with respect to the expected performance if used for the thicknesses of the sealing profiles, but not sufficient in the flattened area of the fixing tape.
  • the fixing tape is integral with the sealing profile, one is tied to the material of the latter, which is often not compatibile with particular materials (generally textiles) used in special applications, with which they do not join firmly to create an optimal seal.
  • An object of the present invention is to eliminate the drawbacks encountered in the zip fastener according to patent EP 933036.
  • an object of the invention is to provide a watertight zip fastener able to impart a barrier effect.
  • Another object of the invention is to provide a watertight zip fastener able to give the protective article uniformity of the textile materials used.
  • Yet another object of the invention is to provide such a watertight zip fastener with the desired characteristics of physico-chemical resistance and with improved resistance to lateral traction stresses.
  • the watertight zip fastener according to the invention structurally corresponding to that of patent EP 933036, is characterized in that it provides a strip of waterproofed fabric with a barrier effect, integrally coupled to the seal profile.
  • a pre-perforated fabric edge is interposed and forced between the mechanical engagement elements and the seal profile.
  • Figure 1 is a partial axonometric view of a zip fastener according to the invention, with a slider shown exploded;
  • Figure 2 is a diagrammatic view showing the elements forming the zip fastener of Figure
  • the zip fastener according to the invention shown partially, has been designated as a whole by reference numeral 1. It comprises two half- chains or seals 2, forming part of a single elastic element 100, or linear profile, obtained by means of a single molding operation, two membranes 3, constrained to the seals in the manner that will be described hereunder, two series of opposed teeth or engagement elements 20 fixed to the seals 2, and a slider 31 which by sliding on the engagement elements 20 causes closure of the two seals 2 of the elastic element 100.
  • Each seal 2 has a substantially U-shaped section, the branches of which form a double lip 10, each presenting a contact surface 11 that abuts tightly against the contact surface of the opposite lip.
  • each U-shaped seal 2 On the base side of each U-shaped seal 2 there is an alveolar rib 14 passed through by a series of through cavities 13, substantially oval in shape, suitable for housing the mechanical engagement elements 20.
  • the series of engagement elements or teeth 20 are carried by respective joining cords 21.
  • Each tooth 20 comprises a heel 22, a lowered central body 26 and a retaining head 27.
  • the lowered body 26 is suitably sized with respect to the cavities 13 of the alveolar rib 14, so as to dilate the cavity 13 which receives it until it is stably retained therein.
  • the structure of the zip fastener according to the invention substantially corresponds to that of patent EP 933036, and therefore will not be further described.
  • Each membrane 3 conveniently consists of a strip of waterproofed fabric with a barrier effect and presents, near its free longitudinal edge, a series of holes 30, able to be disposed in alignment with the series of cavities 13 of the seals 2 and to accommodate the lowered body 26 of the engagement elements 20, so that the membrane 3 remains interposed and firmly held between the engagement elements 20 and the respective seal 2, as shown in Figure 1.
  • membranes 3 can be can be fastened in advance to the seals 2, for example by means of welding, structural bonding or vulcanization, so that the cavities 13 and the holes 30 can be produced by means of a single stepped perforation operation.

Abstract

L'invention porte sur une fermeture à glissière étanche à l'eau, avec un effet de barrière (100), qui est constituée d’une paire d'éléments d'étanchéité opposés (2) destinés à recevoir une série respective d'éléments de mise en prise (20) qui peuvent être amenés en prise mutuelle au moyen d'une coulisse (31) et d’une paire de membranes (3) capables de  relier lesdits éléments d'étanchéité (2) à l'article auquel est appliquée la fermeture à glissière (1), chacune desdites membranes (3) étant un élément séparé de l'élément d'étanchéité correspondant (2) et lesdites membranes étant interposées entre l'élément d'étanchéité (2) et ladite série d'éléments de mise en prise (20).
