Definitions

  • a water-tight slide fastener in which helicoidal or meandering continuous coupling elements have spaced convex heads engaging respective continuous strips of elastomeric material along the other coupling element having outwardly concave portions between the heads and dished sockets complementarily engaging the heads of the other coupling element and resiliently compressible thereby.
  • slide-fastener arrangements have generally comprised a pair of fluid-impermeable support tapes or hands disposed along opposite edges of the surfaces to be united by the slide fastener and carrying the slide-fastener coupling members in lluid impermeable connection with the respective support bands.
  • the slide-fas tener halves are interfitted by the slider in the usual manner except that a tight seal is obtained between the two halves by rubber sealing strips which are brought together under pressure by the uniting of the slide-fastener halves.
  • Such arrangements involve the use of special sliders and special fastener or coupling chains.
  • chain is intended to refer to the coupling members of the slidefastener halves and such members have hitherto involved spaced-apart metallic or synthetic-resin members adapted to be interleaved between corresponding members of the other slide-fastener half as well as continuous undulating, helical, meandering or wave-like elements, usually of a linear polymeric material (e.g. nylon or other polyamide) whose turns interfit with the turns of a cornplementary coupling element in a similar manner. Since conventional water-tight slide fasteners require specially designed coupling members, the manufacturing processes for such members have to be modified by comparison with the usual manufacturing steps while available coupling members cannot be employed.
  • a linear polymeric material e.g. nylon or other polyamide
  • a further object of this invention is to provide an improved slide-fastener arrangement which does not require special manufacturing steps for the coupling members and can be readily adapted to substantially any closure purpose.
  • Yet a further object of this invention is to provide a relatively inexpensive, compact and effective water-tight slide-fastener closure arrangement.
  • a slide-fastener arrangement which includes a pair of continuously interfitting closure members amxed to and running along respective elongated carrier bands and provide with respective elastomeric masses within the coupling members (preferably substantially encapsulating same) adapted to bear upon portions of the other slide-fastener half upon interconnection of the coupling members.
  • This improvement is particularly applicable to coupling members of the so-called helical or meandering type wherein a multiplicity of formations is provided along a strip of filament or a synthetic resin such as nylon.
  • Such helical or meandering elements can have various configurations, as is well-known in the art; for example, the turns of the helix may be of elliptical axial projection while the spaced-apart formations may be enlarged or provided with protuberances engageable between adjacent turns of the other coupling member or co-operating with complementary recesses thereof.
  • the coupling members of this invention are formed in the usual manner from a synthetic-resin filament, preferably of the orientable, linear-polymer type, best results being obtained with linear polyamides such as nylon and thermoplastic which, like nylon, can be set in the desired configuration.
  • the coupling members are mounted in a water-tight manner upon respective fluid-impermeable carrying bands or tapes while the elastomeric masses extending continuously along these coupling members are preferably composed of a syntheticresin-type elastomer.
  • the synthetic-resin masses along each of the coupling members are pocketed between the respective male formations to accommodate the male formations of the other coupling member when the two are drawn together and interfitted by the slider.
  • these pockets may be constituted as recesses generally in the plane of the coupling member, i.e. a plane parallel to the carrying bands, although it has been found to be highly advantageous to enclose these recesses above and below this plane, i.e.
  • the coupling members can be stitched onto their respective carrying bands or manufactured integrally therewith (e.g. by heat bonding) using any of the methods commonly employed heretofore for the assembly of meandering or helical slide-fasteners halves.
  • a mass of elastomeric material is deposited and thereby bonded either to the slide-fastener tape or to the coupling member or, preferably, to both.
  • a further feature of this invention resides in the provision of means for sealing the assembly in the region of the slider in a closed condition of the assembly. It is common practice to provide the usual slide-fastener slider with a projection extending between the coupling members in order to facilitate the opening and closing thereof and this projection frequently gives rise to fluid penetration in conventional arrangements. I have found that it is possible to substantially completely avoid such leakage by disposing in the region of the slider station, in the closed condition of the device, an elastomeric backing sheet which is affixed to the carrier bands. and bears upon the coupling members and the slider at this station with a resilient sealing force.
  • this resiliently compressible backing member is supported further by a rigid link spanning the bands and underlying the backing member to prevent deflection thereof while permitting its resilient compression by the slider as it is displaced to and from this station.
  • slide fasteners of the aforedescribed type are produced by an improved process which involves the molding of the elastomeric material, e.g. a foamed thermoplastic, around at least the coupling members by deposition or extrusion of the plastic material around a continuously moving slide-fastener half; it is thus also possible to roll the thermoplastic material into the coupling members in a continuous manner.
  • the elastomeric material can then be applied to each of the coupling halves separately and only subsequent to setting is the fastener closed.
  • the elastomeric material is a polyurethane or other thermosetting substance, the setting can be effected prior to the closure of the members.
  • the elastomeric material can be applied to the closed slide-fastener assembly by extrusion or rolling and, after only partial setting, compressed and permitted to set fully so that the elastomeric material will exert a sealing force upon the interfitting portions of the coupling members.
  • a better fit of the elastomeric material to the male portions of the slide-fastener turns or heads is obtained.
  • a parting compound can be a silicone or the like as is commonly used in the casting industry for preventing adhesion of elastomeric molds to elastomeric materials or other surfaces.
  • the carrier bands if they are of a textile material, the stitching holes and the like do not form fluid passages.
  • the elastomeric mass can form a monolithic coating for the entire band and the connecting threads and fillets employed to join the cou pling members to the band.
  • the spray or injection device When the solvent-thinned thermoplastic resin is deposited upon the band provided with the coupling member, it is desirable to provide the spray or injection device with a further nozzle opening for dispensing a stream of the thermoplastic material sufficient to completely envelop the connecting threads and fillets and to fill the stitch holes. It is, however, also possible to coat the band and/or the coupling member and then join them together although stitching is, in this case, rendered difficult by the considerable friction coefficient of the elastomeric coating. Thus, I prefer to attach the coupling member to its carrier band with an adhesive or to thermally bond the parts together when they are to be joined after application of the elastomeric material thereto.
  • the encapsulating of the coupling member and/or the band or the entire slide-fastener assembly is carried out by extrusion of the material around the assembly, member or band with the aid of an extnusion press whose die is formed in the manner of cable-sheathing dies.
  • the band, member or assembly can be drawn through the die as the elastomeric mass is extruded around them.
  • FIG. 1 is a perspective view of a completed slidefastener assembly according to this invention
  • FIG. 2 is a perspective view of a deformed portion of one slide-fastener half in accordance with this invention
  • FIG. 3 is a cross-sectional view taken generally along the line III-III of FIG. 1;
  • FIG. 4 is a cross-sectional view corresponding generally to FIG. 3 but illustrating another embodiment of this invention.
  • FIG. 5 is a view similar to FIG. 4 of the same open condition.
  • FIGS. 1-3 I show a slide-fastener assembly whose carrying bands or tapes 1, 1" of the respective slidefastener halves each carry a respective helical coupling member 2, 2"; the latter interfit as illustrated at 2a to form the closure.
  • the coupling members 2 and 2" are conventionally formed from a linear-polyamide filament by heat setting and are joined to the respective carrying tapes 2' and 2 which can be composed of rubber or rubberized fabric and thus are fluid impermeable or can be made so. Coupling members of this type are well known in the art and, as illustrated in greater detail in FIG.
  • the coupling members 2' and 2 are attached to the respective bands 1', 1" by chain-stitching, fillets or the like as represented generally at 6.
  • the slide-fastener heads are joined by endstop members 7a and 7b in the usual manner, these stop members preventing the withdrawal of the slider 8 from the closure assembly.
  • an elastic backing member 9 spanning the tapes 1' and 1" and cemented to the underside thereof so as to bear tightly upon the underside of the slider 8 in the region of the position of the slider in the closed condition of the assembly.
  • This backing member 9 is cemented to the bands 1' and 1" at least along the periphcries of the bands but possibly also substantially to the zone in which the coupling members 6 are stitched thereto so that the backing member 9 presses as tightly as possible against the underside of the slider 8 and the coupling members 2', 2" in the region thereof.
  • I provide a reinforcing link which supports the backing member 9 in the region of the slider position when the fastener assembly is closed.
  • This rigid link 10 is composed of metal and, as is best illustrated in FIG. 3, can be joined to the backing member 9 and the tapes 1' and 1 by large-head hollow rivets 10' and 10.
  • the stitches 6 securing the coupling members 2' and 2 to the tapes 1' and 1 are coated with elastomeric material 11 which also serves to fill the holes in the tapes produced by the sewing operation and prevent the passage of fluid along the stitches.
  • the elastomeric mass 11 can be applied by dipping of the band or by strip-application of the material in the liquid state followed by curing or volatilization of the solvent.
  • FIGS. 4 and 5 show a modified slide-fastener arrangement wherein the bands 101 and 101" are composed of a fluid-permeable maaterial such as a textile fabric.
  • the helical slide-fastener halves 102, 102" are attached to the strips 101' and 101 With the aid of fillets 115 and 115" extending through the coupling members 102, 102" and fixed to the bands 101' and 101" by transverse stitches 116', 116".
  • the synthetic-resin sealing masses 103' and 193 of these coupling members encapsulate the coupling members 102', it and are monolithic with respective layers 103a, 103a", completely sheathing the respective bands 101 and 101".
  • the synthetic-resin thermoplastic elastomer can be formed by spraying a solvent-diluted solution of the synthetic resin onto the assembled slide-fastener halves by extruding the elastomeric mass around the slide-fastener members as indicated earlier.
  • the synthetic-resin sealing masses are provided with respective pockets 105, 105" shaped to receive the ends 102a and 102a which are provided with heads 104', 104", respectively. Flanking the pockets 105', 105", the sealing strips of elastomer 103', 163" are formed with confronting lips 112a, 112a" and 1112b, 1121) adapted to bear upon each other in the closed condition of the fastener (FIG. 4). The contact of these lips is effected in the separating plane S under the pressure of the resiliently compressed lips which, therefore, extend beyond the pockets Hi5, 1&5" and preferably are coplanar (planes S and S" of FIG.
  • a fluid-tight slide fastener assembly comprising:
  • each of said coupling members being a continuous member formed with longitudinally spaced heads forming said interfitting portions, said strips of elastomeric material being respectively continuous and formed with said pockets between the heads of the respective coupling member;
  • stitching means for connecting each of said coupling members to the respective band
