Definitions

  • ABSTRACT There is disclosed -a sliding clasp fastener comprising a pair of oppositely disposed stringer tapes each carrying along their'respective longitudinal edges on one surface a series of discrete molded or die cast elements.
  • Each element is provided in one surface with a recess or indent disposed for reception therein of a marginal edge portion of the stringer tape with a view to reducing the overall thickness of the fastener.
  • This invention relates to sliding clasp fasteners having opposed stringer tapes of the type wherein the fastener elements are attached by injection or die casting to one surface of the respective stringer tapes.
  • fastener elements are mounted and fixed on only one surface of the stringer tapes so as to leave the other surface, facing toward the garment, free of fastener elements.
  • one-sided fasteners have suffered from the disadvantages that the protrusion of fastener elements above the one surface of the stringer tapes is literally so much greater, which in turn reduces the strength of adhesion of the fastener elements relative to the stringer tapes and which further creates the tendency of such protruding elements to catch the garment or other objects thereby damaging the latter or the fastener itself.
  • a simple solution to this problem would be to reduce the thickness of the fastener elements as measured in a plane perpendicular to the plane of the fastener.
  • too thin fastener elements would result in reduced strength of coupling between the elements and would be liable to disengagement from one another.
  • Another object of the invention is to provide improved sliding clasp fasteners of the type described whose elements are secured firmly into position on one surface of the fastener.
  • FIG. 1 is a plan view of a sliding clasp fastener embodying the invention
  • FIG. 2 is a sectional view taken along the line IIII of FIG. 1;
  • FIG. 3 is a perspective view of the reverse side of the fastener shown in FIG. 1;
  • FIG. 4 is a perspective view of a modification according to the invention.
  • FIG. 5 is a sectional view of a half portion of another modified fastener according to the invention.
  • FIGS. 1 to 3 there is shown a sliding clasp fastener 10 which comprises a pair of oppositely disposed stringer tapes ll, 11 each carrying along their respective longitudinal edges l2, 12 on one surface a series of molded or die cast discrete coupling elements 13.
  • Each element 13 consists of an upper coupling member 14 including at opposite sides protuberances l5, l5 and reduced neck portions or sockets 16, I6 engageable with the protuberances l5, 15 of the upper coupling member 14 on the companion stringer tape to establish a coupling engagement of the elements 13 in a horizontal direction and a lower coupling member 17 substantially rectangular in shape with its outer end terminating short of the outer end of the upper coupling member 14 and engageable with the lower face of the upper coupling member 14 on the companion tape to establish a coupling engagement in a vertical direction, as seen in a conventional structure.
  • the coupling elements 13 further consists of a leg portion 18 extending opposite to the coupling members 14, 17 and disposed for attachment to the longitudinal edge 12 of the tape 11.
  • the indent 19 has a depth approximating the thickness of the stringer tape 11 such that the end face 22 of the longitudinal edge 12 of the tape 11 is held in abutting relation to the vertical wall 20 and the upper surface 11 of the tape 11 is superposed on and affixed to the bottom wall 21 of the leg portion 18, thus securing the elements 13 firmly through two contact surfaces into position on the fastener 10.
  • the elements 13 may be stitched as at 25 along the longitudinal edges 12, 12, for which purpose there is provided a stitch-receiving recess formed in the upper surface of each element 13 as shown, whereby the stitchings 25 run substantially parallel with the longitudinal ridge 23.
  • FIG. 4 there is shown a modified form of element 13 wherein the lower coupling member 17 is triangular in shape with its apex 26 registering with the outer end of the upper coupling member 14.
  • Another feature of this embodiment is found in the provision of a larger bead-like ridge 23 and a correspondingly large groove 24 for embracing the same, whereby sufficient adhesion is obtained between the element and the tape without the necessity of providing stitches 25.
  • FIG. 5 shows another moodification wherein the lower coupling member 17 has a height H greater than the thickness T of the tape 11.
  • a sliding clasp fastener comprising, a pair of opposed stringer tapes, and a plurality of coupling elements disposed along and secured to a pair of adjacent longitudinal edge portions of said stringer tapes on corresponding upper surfaces of said tapes, wherein each of said coupling elements comprises;
  • leg portion integral with said upper coupling member and said lower coupling member and extending therefrom, said leg portion having an upper surface even with said upper surface of said upper coupling member, and a lower surface, said leg portion having a thickness substantially equal to said upper coupling member thickness, said lower coupling member terminating at a rear edge portion, said rear edge portion together with said lower surface of said leg portion defining an indentation having a depth approximately equal to a thickness of said stringer tapes and comprising a surface contacting the upper surface of one of said tapes and said edge portion contacting a longitudinal edge of said one of said tapes.
  • a sliding clasp fastener as defined in claim 1 wherein there is provided a groove in the first surface of said indentation for engagement with a correspondingly shaped bead-like ridge projecting from the upper surface of the tape.
