Definitions

  • a sliding clasp fastener is provided with a top end stop for terminating the movement of a slider at the top [52] U.S. Cl. 24/205. F end of the fastener, which end stop comprises a pair of [51] Int.
  • PATENTEB JANZ 8 I975 v SHEET 2 BF 2 FIGS l k ii 5 a m $111 (St. 10i.
  • This invention relates to a sliding clasp fastener and has particular reference to means for stopping the movement of a slider at a predetermined point on the top end of the fastener to prevent the same from running off the fastener elements.
  • One such known end stop is formed by simply thermally deforming plastic fastener elements attached to the stringer tapes of the fastener. Although this is simple in the manufacture, it is made up of only limited quantity of a plastic material and is liable to damage from repeated impinging contact with the slider.
  • Another conventional end stop consists of a plastic strip or film adhered by heat and pressure to a relatively large area of the stringer tapes including the beaded edges thereof which are rendered rigid by impregnating a plastic material of the strip, with fastener elements removed off the portion of the beaded edges which lies opposite to the guide flange surface of the slider when brought into stopped position.
  • This type of end stop renders the movement of the slider rather heavy and sluggish particularly when the same is manipulated to start off in a direction to open the fastener.
  • a more specific object of the invention is to provide an improved means of stopping the slider at a desired point on the top end of a sliding clasp fastener, which means will facilitate the starting movement of the slider off said point to open the fastener.
  • Another specific object of the invention is to provide an improved top end stop means which will prohibit the tendency of opposed stringer tapes at an extreme end of the fastener beyond the location of said stop means to flare apart or diverge relative to the longitudinal axis of the fastener.
  • FIG. 1 is a plan view of a sliding clasp fastener having mounted thereon a slider and an end stop means shown in engagement therewith;
  • FIG. 2 is a plan view of one of the two stringer tapes of the fastener of FIG. 1, in which the coupling heads of some of the fastener elements embraced by the stop means are removed;
  • FIG. 3 is a transverse cross-sectional view taken along the line III-III of FIG. 2;
  • FIG. 4 is a plan view similar to FIG. 2 but showing the coupling heads of some of the fastener elements retracted at the stop means to lie flush with the beaded edge of the stringer tape;
  • FIG. 5 is a plan view of a modification of the stop means shown in FIG. 1;
  • FIG. 6 is a transverse cross-sectional view taken along the line VI-VI of FIG. 5.
  • FIG. 1 there is shown a sliding clasp fastener 10 of the type which comprises a pair of opposed stringer tapes 11,11 each carrying along their respective longitudinal beaded edges 12,12 a row of inter locking fastener elements 13 formed from a continuous plastic filament and a slider 14 mounted on the fastener 10 for reciprocal movement along the beaded edges 12,12 to take the fastener elements 13 into and out of engagement with one another; namely, to close and open the fastener 10 in a well known manner.
  • the slider 14 partly shown in FIG.
  • 1 is of the usual construction consisting generally of spaced-apart upper wing (not shown) and lower wing 1411, respectively, inwardly bent to form side flanges 14b,l4b and connected by a neck in such a manner as to provide substantially a Y-shaped channel for guiding the movement of the fastener elements 13 therethrough.
  • a top end stop means generally designated 15 which is adapted to restrict or terminate the movement of the slider 14 at a predetermined point adjacent to the top end region of the fastener 10.
  • the stop means 15 comprises a pair of oppositely disposed slugs 16,16 made of a plastic material such as a thermoplastic resin and secured as by a moulding operation to the respective opposed stringer tapes ll,11 adjacent to the beaded edges 12,12 thereof.
  • Each slug 16 is substantially lobeshaped and has a longitudinal linear edge 16a extending inwardly of and substantially in parallel with the beaded edge 12, a bottom end 16b disposed substantially at right angles to the longitudinal edge 160, a cam surface contiguous to the bottom end 16b and consisting of a first contour or guide surface 160, configured to match a flared inner guide wall 14d of the slider 14 and a second contour or abutment l6c disposed in abutting relation to the upper flange end Me of the slider 14 as depicted in FIG. 1.
  • the coupling head portions 13a of a fastener element or elements 13 encompassed by the slug 16 on each stringer tape 11 and located at a point opposite to the guide surface 160, of the slug 16 are retained or survived thereat without being removed, while the coupling heads 13a of the remaining elements embraced by the slug 16 are either cut off as shown in FIGS. 1, 2 and 5 or displaced or retracted laterally away from the beaded edge 12 of the tape 11 as shown in FIG. 4.
  • the said remaining elements 13 that are exposed on the beaded edge 12 should extend fully up to its extremity or marginal line 12a as best depicted in FIGS. 2 to 4.
  • the starting movement of the slider 14 is improved by the provision of the fastener element or elements 13 which lie opposite to the guide surface 160, and which have their respective uncut coupling heads 13a disengaged from the corresponding ones on the mating stringer tape 11 to permit the passage therethrough of the neck 140 of the slider 14.
  • FIGS. 5 and 6 there is shown a modification of the stop means 15 according to the invention wherein the opposed slugs 16,16 consituting the stop means 15 are each reinforced with integral thinned foil member 17 of which plastic material penetrates into and is adhesively bonded to the fabric of the stringer tape 11, thereby securing the slug 16 firmly into position on the fastener 10.
  • Wl-Iat is claimed is:
  • a sliding clasp fastener of the type which comprises a pair of oppositely disposed stringer tapes each carrying along their respective longitudinal edges a row of interlocking fastener elements made of a continuous plastic filament and a slider having side flanges including an inner guide wall and an upper flange end and mounted on the fastener for reciprocal movement along the said longitudinal edges, a top end stop means which comprises a pair of oppositely disposed slugs of a plastic material secured to the respective opposed stringer tapes adjacent to the beaded edges thereof.
  • each of said slugs having a longitudinal linear edge extending inwardly of and substantially parallel to the beaded edge, a cam having cam surfaces on each of said slugs contiguous to said linear edge, and disposed in abutting relation to said inner guide wall and said upper flange end of the slider.
  • said pair of slugs embracing a group of fastener elements of which the elementor elements of said group located at a point opposite to said cam have their coupling heads intact and disengaged from the corresponding ones on the mating stringer tape, with the remaining elements in said group having ends registering with an extremity of the beaded edge of the tape.
  • each of said slugs is reinforced with a thinned foil member integrally formed therewith and adhesively bonded to the fabric of the stringer tape.
