Definitions

  • ABSTRACT -A concealed zip fastener is provided with a series of spaced element-receiving openings aligned longitudinally along a reinforced marginal edge of each of two opposed carrier tapes and defining a line of fold along which the tape is folded. These openings are adapted to hold therein a portion of an interlocking fastener element of a meandering form.
  • a row of fastener elements is secured to the folded edge of the tape by a line of stitchings running closely along said series of openings in a manner that the tape resists lateral displacement when lateral stresses are applied in a direction to pull apart the junction of the opposed tapes.
  • This invention relates to zip fasteners, more particularly to a slider-operated fastener of the concealed or masked type which in its closed disposition substantially simulates a garment seam.
  • Zip fasteners having two rows of interlocking fastener elements formed from a continuous filament or wire and secured to respective folded edges of opposed stringer tapes are well known, and such fasteners when closed by the slider mask the elements from external view, only leaving a linear seam in the junction of the opposed tapes.
  • fastener elements adapted for such concealed fasteners; one is a spring coil or helix form such as shown in FIG. 8, and the other is a meander or zig-zag form such as shown in FIG. 9.
  • the former type of fastener has interlocking elements simply sewn to the folded marginal edge portions of the opposed tapes, and is liable to crack open at the junction of the tapes when lateral forces are applied in the direction of the arrow, viz. in a direction to split the two tapes apart.
  • the latter type of concealed fastener has the folded edges of two opposed tapes embedded between and sewn to the leg portions of the meandering elements and is liable to suffer from deformation of the elements under the influence of the abovementioned lateral forces.
  • FIG. 2 is a perspective view of the fastener of FIG. 1 with part cut away;
  • FIG. 4 is a transverse sectional view of one of two similar segments of a concealed fastener embodying the invention.
  • FIGS. 5 7, inclusive are transverse sectional views illustrating different modifications of the concealed fastener of the invention.
  • FIG. 9 is a transverse sectional view of a conventional meander-type concealed fastener.
  • the concealed zip fastener comprises a pair of opposed carrier tapes each having an inwardly folded reinforced edge and a series of spaced element-receiving openings aligned along said folded longitudinal edge and defining a line of fold along which the tape is folded, a row of interlocking fastener elements in a meandering form each of which elements having a coupling head portion, merging upper and lower leg portions, a first base portion associated with said upper leg portion and a second base portion associated with said lower leg portion and connecting between adjacent elements, said first base portions being inserted in said openings, at first line of stitchings securing both leg portions adjacent said coupling head to said folded edge and running substantially along said line of fold and a second line of stitchings securing said lower leg portion to said folded edge.
  • FIGS. 1 through 3 inclusive illustrate a most preferred form of the present invention
  • a concealed or masked zip fastener generally designated 10 which comprises a pair of opposed carrier tapes T, T each having mounted thereon a row of interlocking fastener elements E of a meandering form.
  • Each carrier tape T as better seen in FIG. 3, is provided with a thickened or otherwise reinforced longitudinal edge 11 and a series of spaced element-receiving openings 12 aligned therealong, more specifically closely along a boarder line 13 between a web portion Ta and the reinforced edge 11.
  • Each individual interlocking fastener element Ea has a coupling head portion 14, merging upper and lower leg portions respectively designated 15 and 16 and base portions 17a and 17b extending respectively from the upper and lower leg portions 15 and 16 and connecting between adjacent elements Ea.
  • the upper leg portion 15 contiguous to and extending from the coupling head portion 14 is shorter than the lower leg portion 16 and is bent upwardly at a point near its associated base portion 17a to make the latter rise as at 17 and project substantially vertically as shown in FIG. 3.
  • the upwradly projecting base portions or lugs 17 of the successively interconnected elements Ea are inserted in the element-receiving openings 12 arranged longitudinally along the boarder line 13.
  • the elements E are secured to the carrier tape T by a first line of stitchings S running substantially along the boarder line 13 or closely along the series of element-receiving openings 12 and spanning between the lower leg portions 16 close at the coupling heads 14 and the boarder line 13 of the tape T.
  • the carrier tape T is now folded on itself along the first line of stitchings S to reveal an external folded edge 19 which forms with corresponding edge 19 of the mating tape T a junction simulating a garment scam, in which instance the internal folded edge 20 (20) is borne against and supported by the upwardly projecting base portion or lug 17 so that the carrier tape T resists thereat against lateral displace ment when lateral stresses are exerted to pull the junction apart.
  • the reinforced edge portion 11 is snugly fitted in the oblong spaces 18 and anchored in place there by a second line of stitchings S which extends therethrough and spans between the lower leg portions 16 and merging upper regions 16" at a point adjacent the upstanding region 16' as shown in FIGS. 1 and 2.
  • the concealed zip fastener of the invention can maintain its normal correct posture against severe stresses applied in a direction to pull the opposed tapes apart at their junction which would otherwise cause the tapes to shift laterally away from each other to expose the elements E to external view.
  • the fastener elements E of the unique construction described and illustrated as attached to the respective carrier tapes T, T tend to absorb or cancel out lateral stresses by resilient compression between the upper and lower leg portions to tighten them harder without presenting any physical deformation.
  • the zip fastener 10 retains its concealing or masking function as desired of this type of fastener under severe stresses.
  • FIG. 4 omits the provision of the upwardly projecting lug 17' but aims to retain the positional stability of the carrier tapes T, T by the anchoring effect provided by the element-receiving openings 12 and the first line of stitchings S securing the elements E closely at their base portions 17a contiguous to the coupling head portions 14.
  • FIG. 5 shows another modification wherein the lower leg portion 16 is folded inwardly towards the coupling head portion 14 in a manner similar to a hair pin, forming a clearance 31 at the fold for receiving a filling core or stiffening cord 32, and the reinforced edge portion 11 of the tape T is rested on the folded upper region 16" of the lower leg 16.
  • FlG. 7 shows still another modification which is identical with the most preferred embodiment shown in FIGS. 1 3 only with the exception that the upstanding region 16 contiguous to the lower leg portion 16 is reduced in its length so that the base portion 17b associated therewith lies flush with the upper leg portion without being inwardly bent, and hence the second line of stitchings S spans between the lower leg portion 16 and the upper surface of the reinforced edge: 11.
  • a concealed slide fastener comprising, a pair of carrier tapes each having an inwardly folded reinforced longitudinal edge and a series of apertures aligned along said folded longitudinal edge and defining a line of fold along which the tape is folded, a row of coupling elements each having a coupling head, upper and lower leg portions extending from said coupling head in a transverse common direction of said row of coupling elements wherein said lower leg portion extends a greater distance than said upper leg portion, said upper leg portion being provided with a bent portion at an end remote from said coupling head and extending in a direction transverse to said row of coupling elements and away from said lower leg portion, an upstanding portion extending from an end of said lower leg portion opposite said coupling head in a direction essentially parallel thereto, an upper portion extending from an end of said upstanding portion opposite said lower leg portion in a direction toward said coupling head and essentially parallel to said lower leg portion, a lower base portion extending from an end of said upper portion opposite said upstanding portion in a lateral direction of said row of
  • a concealed slide fastener comprising, a pair of carrier tapes each having an inwardly folded reinforced longitudinal edge and a series of apertures aligned along said folded longitudinal edge and defining a line of fold along which the tape is folded, a row of coupling elements each having a coupling head, upper and lower leg portions extending from said coupling head in a transverse common direction of said row of coupling elements wherein said lower leg portion extends a greater distance than said upper leg portion, said upper leg portion being provided with a bent portion at an end remote from said coupling head and extending in a direction transverse to said row of coupling elements and away from said lower leg portion, an upper portion extending from an end of said lower leg portion remote from said coupling head and reversely bent toward said coupling head and curved toward said lower leg portion so as to contact said lower leg portion, a lower base portion extending from an end of said upper portion near said coupling head in a lateral direction of said row of coupling elements and connecting to a lower base portion of a next adjacent coupling element, an
