  • a water-tight fastener for use in articles, such as water-tight boots, raincoats, water-tight trousers, and the like, which comprises two opposite rows of engaging teeth supported by separate cloth pieces at the inner side edges of the latter for meshing with each other, a slidable fastening means in engagement with said opposite rows of engaging pawls for movement between a fastener closing position and a fastener opening position, resilient water-tight pieces each attached to the exposed side of each of said teeth-supporting cloth pieces and having the inner side edge extending beyond the adjacent edge of the associated teeth-supporting cloth piece, said inner side edges of the watertight pieces being adapted to abut against each-other when said fastener is closed thereby to provide a watertight seal therebetween and at the same time, to completely cover said engaging teeth, and at least one water-tight reinforcement attachment provided at the base end of said fastener on one side thereof.
  • FIG. I is a plan view of a first embodiment of watertight fastener constructed in accordance with the present invention with a portion thereof taken away;
  • FIG. 2 is a reverse side view of FIG. 1;
  • FIG. 3 is a cross-sectional view of said water-tight fastener of FIG. 1 on an enlarged scale;
  • FIG. 4 is a fragmentary cross-sectional view of the right-half portion of FIG. 3;
  • FIG. 5 is a cross-sectional view of a second embodiment of watertight fastener constructed in accordance with the present invention.
  • FIG. 6 is a fragmentary sectional view of the righthalf portion of FIG. 5;
  • FIG. 7 is a cross-sectional view of a third embodiment of watertight fastener constructed in accordance with the present invention.
  • FIG. 8. is a fragmentary cross-sectional view of the right-half portion of FIG. 7.
  • the fastener comprises selectively engageable fastenable means, such as two opposite rows of engaging teeth 1, which are respectively secured in an equally spaced relationship to first members, such as opposite narrow teeth-supporting cloth pieces 2 and 3.
  • the teeth-supporting cloth pieces 2 and 3 have on one side thereof water-tight second members, such as elastic water-tight pieces 4 and 5, respectively, secured thereto by means of gluing, for example.
  • Each of the engaging teeth 1 in one row has an engaging tip end I for meshing with the corresponding one of the similar teeth 1 in the opposite row.
  • the elastic water-tight pieces 4 and 5 are formed of rubber, synthetic resin, or the like, and have a width greater than that of the teeth-supporting cloth pieces 2 and 3. Each of the water-tight pieces 4 and 5 is glued to the outer side edge of the associated teeth-supporting 3 cloth piece 2 and 3, respectfully, on the side of the latter where the water-tight piece is exposed when the entire fastener is attached to an article ready for use.
  • the inner edges of the teeth-supporting cloth pieces 2 and 3 are bent downwardly, and then outwardly to be received and tightly held in the respectively associated teeth 1.
  • the inner side edge 7 of each of the elastic water-tight pieces 4 and 5 is bent downwardly, and terminates short of the extreme inner side edge of the associated pawl-supporting cloth piece.
  • the inner side edges 7 of the water-tight pieces 4 and 5 are adapted to be urged against each other as the fastener is closed in the manner as will be described hereinafter.
  • a slidable fastening means 6 is provided for moving between a fastener opening position wherein the fastening means is positioned at the extreme right-hand end of the opposite rows of engaging teeth 1, and a fastener closing position wherein the fastening means is positioned at the extreme left-hand end of the rows of engaging teeth, as seen in FIGS. 1 and 2.
  • the fastening means 6 slides along the opposite rows of engaging teeth 1 from the opening position toward the closing position, the successive engaging teeth 1 in one row firmly engage or mesh with the corresponding engaging teeth 1 in the other row in a staggered relationship as seen in any of the conventional corresponding fasteners, but in the fastener of the present invention, the successive areas of the inner side edges 7 of the water-tight pieces 4 and 5 are urged to firmly abut against each other to provide a water-tight seal therebetween as the successive engaging pawls 1 in the opposite rows mesh with each other as mentioned hereinabove.
  • the opposite side edges of the article are passed over the underside of the outer side edges 8 of the water-tight pieces 4 and 5 to intermediate positions of the underside of the outer side edges of the teeth-supporting cloth pieces 2 and 3 and then glued to the water-tight pieces and teeth-supporting cloth pieces.
  • a water-tight attachment or reinforcement piece 9 is glued to the end base or right-hand end of the fastener on the exposed side thereof across the water-tight pieces 4 and 5, and a second or axuiliary water-tight reinforcement piece 10 is also glued to the base end of the fastener on the reverse or opposite side thereof in a displaced relationship to the first-mentioned water-tight reinforcement piece.
  • the provision of the auxiliary water-tight reinforcement piece 10 is for the purpose of increasing the reinforcement of the fastener, and, if desired, the auxiliary water-tight reinforcement piece 10 may be eliminated.
  • FIGS. 5 and 6 show the second embodiment of water-tight fastener of the invention in cross-section.
  • the second embodiment is substantially similar to the first embodiment of FIGS. 1 through 4 except for that the inner side edges 7 of the water-tight pieces 4 and 5 extend underneath the inner side edges of the pawl-supporting cloth pieces 2 and 3 to be firmly held within the respectively associated teeth 1 so that the inner side edges of the water-tight pieces will abut against each other to provide a watertight seal therebetween as the fastener is in its closed position.
