Definitions

  • a slide fastener is provided with two slide members which can engage each other with unsymmetrical notches formed in their ends while one row of closure members of a zipper is being introduced therein.
  • the unsymmetrical notches are formed from at least one tooth and at least one associated complemental tooth gap, both as seen in top plan view, so that the unsymmetrical notch of one slide fits into the unsymmetrical notch of the other slide for purposes of maintaining alignment.
  • An additional notch may be provided in each slide, as viewed in sideview, for further aligning the two slides.
  • the invention refers to a zip-fastener provided with two rows of closure members, said rows of closure members being completely separable from one another, and further provided with two slides for opening and closing, respectively, the zip-fastener in opposite direction, said slides being safely held on one row of closure members and being adapted for introducing the end of the other row of closure members when said slides are in engagement with its opposing front faces.
  • zip-fasteners of the kind described said both slides bluntly engage one another with its front faces when being in the position for introduction of the end of the free row of closure members while being held in its relative position only by the row of closure members which they are engaging.
  • the invention now aims at removing said disadvantages and essentially consists in that the opposing front ends of the slides are engaging one another by an unsymmetric notch and in that the front ends of both slides are equally shaped.
  • This arrangement according to the invention pro vides the advantage that both slides are, by means of its notched front ends, firmly held in a well defined relative position warranting unobstructed introduction of the other row of closure members with its end into both slides.
  • both slides being equally shaped it is possible to manufacture both slides of one zip-fastener with the same tools what materially facilitates production and materially reduces production costs. Provision of one slide with a guide member of special construction would result in different shapes of both slides what would substantially increase production costs.
  • both cover plates of each slide are provided with meshing notches.
  • the flanks of the teeth of the notches 3,583,043 Patented June 8, 1971 are converging seen in a top plan-view, thus facilitating interengaging of the notches. If the flanks of the teeth are, seen in a cross section perpendicular to the direction of movement of the slides, perpendicular to the planes of the cover plates, the relative position of the meshing slides is secured against laterally acting forces and with this introduction of the end of the free row of closure members is substantially facilitated.
  • the slides are with their engaging ends formed such that a notch is present also seen in a lateral view of the slide, said notch preferably having converging flanks too.
  • a notch is present also seen in a lateral view of the slide, said notch preferably having converging flanks too.
  • the arrangement may be such that the flanks of the teeth of the notch are, seen in a cross section perpendicular to the direction of movement of the slides, inclined relative to a vertical line on the plane of the cover plates.
  • Such an arrangement is suitable for maintaining the relative position of the engaging slides against both, vertically and laterally acting forces.
  • FIG. 1 is a top plan-view of the meshing slides seen in direction of arrow I of FIG. 2.
  • FIG. 2 is a cross section along line II-II of FIG. 1 showing only the slide 1.
  • FIG. 3 is a lateral view of the meshing slides shown in FIG. 1.
  • FIG. 4 shows a top plan-view of a further embodiment.
  • FIG. 5 is a section along line V-V of FIG. 4.
  • Both slides 1 and 2 are shown in a position at the end of one row 13 of closure members on which row said slides are guided such that they cannot be lost.
  • Each slide is provided in a manner known per se with a heart piece 17 and a lug 18.
  • both slides precisely mesh with their front ends 3 so that the lateral walls 15, 16 of both guide channels for the rows 13 and 14, respectively, of closure members are exactly aligned.
  • said slides 1 and 2 are of identical shape and are provided at its front ends 3 with an unsymmetric notch.
  • the tooth 4 of one slide is engaging the tooth gap 5 of the other slide and the tooth 6 of one slide is engaging the recess 7 of the other slide, and vice versa. This is enabled by the unsymmetric notch.
  • the meshing teeth hinder the slides 1 and 2 from being shifted relative to one another in the plane a (FIG. 2) of the cover plates 9, 10.
  • both slides 1 and 2 are provided with a notch as is shown in a side elevation represented by FIG. 3.
  • Said notch being formed by protrusions 19 engaging corresponding recesses 20 of the tooth 6 over approximately half of its width.
  • the flanks of the teeth and of the tooth gaps and the recesses, respectively are somewhat inclined relative to the longitudinal axis of the Zipconstruction is simple yet has a suflicient strength to retain securely the strap even if an external force is applied thereto, thus providing very useful advantages.
  • a device for releasably fastening a strap to a body to be suspended comprising a mounting member fixedly secured to the suspended body and having a head, a neck portion and a flanged portion; a retaining member fixed to said mounting member for slidable movement in the axial direction thereof and having an engaging portion; a spring for pressing said retaining member against said flanged portion of said mounting member; and a connecting member having an aperture consisting of two portions, one portion of said aperture being larger than said head first curved portion while the other portion being larger than said neck portion but smaller than said head portion of said mounting member and being defined by a second curved portion, said connecting member having a C-shaped convex portion adapted to engage With said engaging portion of said retaining member and being fastened to the strap.
