Definitions

  • This invention relates generally to slide fasteners and more specifically to a stringer for slide fasteners including a series of discrete fastener elements attached to a warp-knitted fabric tape. Even more specifically, the invention is directed to the improved arrangement of what is herein termed an element connector in the slide fastener stringer of the type just mentioned.
  • An element connector in the form of, for example, a fabric cord or plastic monofilament is customarily employed in combination with discrete fastener elements, in order to maintain the latter at correct longitudinal spacings on a stringer tape.
  • Such element connector is usually arranged along one longitudinal edge portion of the stringer tape so as to extend across the legs of the fastener elements, and those portions of the element connector lying between the adjacent fastener element legs are completely exposed on the stringer tape. It will be apparent that the exposed element conector portions are highly susceptible to damage or wear from repeated contact with other objects in the use of the slide fastener incorporating a pair of such stringers. The damaged or worn element connector can seriously impair the positional stability of the fastener elements, and the slide fastener may eventually become incapable of functioning properly.
  • this invention provides a slide fastener stringer in which there is employed a tape made of a warp-knitted fabric, with transversely alternating wales and inter-Wale grooves formed on at least one surface thereof.
  • a series of discrete fastener elements arranged along one longitudinal edge portion of this stringer tape are of the type each comprising a coupling head and a pair of legs extending rearwardly therefrom, and at least one leg of each fastener element has an inwardly directed midpoint projection or a rear end projection which is received in the respective interwale grooves on one surface of the stringer tape along the longitudinal edge portion thereof.
  • At least one element connector adapted to maintain the fastener elements at preassigned pitch spacings is also received in either of the interwale grooves in which the inwardly directed projections of the legs of each fastener element are received.
  • the element connector moreover, is buried in the interwale groove lower than the outer surfaces of the wales.
  • FIG. 1 is a plan view of a slide fastener stringer constructed in accordance with the novel concepts of this invention
  • FIG. 2 is a sectional view taken along the plane of line IIII in FIG. 1;
  • FIG. 3 is a view similar to FIG. 1 but showing another preferred embodiment of the invention.
  • FIG. 4 is a sectional view taken along the plane of line IVIV in FIG. 3;
  • FIG. 5 is a sectional view similar to FIGS. 2 or 4 but showing still another preferred embodiment of the invention.
  • FIG. 6 is also a similar sectional view but showing a further preferred embodiment of the invention.
  • FIG. 7 is also a similar sectional view in which the concepts of the invention are applied to a slide fastener stringer having one-legged fastener elements.
  • FIGS. 1 and 2 DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • a stringer tape of a warpknitted fabric having Wales 11 on both surfaces of the stringer tape along one longitudinal edge portion 14 thereof, which surfaces are adapted to mount thereon a series of uniformly spaced fastener elements 13 of discrete type. These wales alternate with interwale grooves 12 in the transverse direction of the stringer tape 10.
  • the fastener elements 13 are affixed to the longitudinal edge portion 14 of the stringer tape 10 via a pair of element connectors 15 arranged longitudinally thereof.
  • Each element connector 15 is in the form of a fillet of suitably flexible material such as, typically, plastics.
  • the fastener elements 13 are of the type each comprising a coupling head 16 at its front end and a pair of parallel spaced legs 17 and 18 extending rearwardly from the coupling head, with the legs 17 and 18 arranged in a plane perpendicular to the plane of the stringer tape.
  • a pair of inwardly directed projections 19 are formed correspondingly at the rear ends of the respective legs 17 and 18 of each fastener element 13.
  • Another pair of inwardly directed projections 20 are formed correspondingly approximately at the midpoints of the respective legs of each fastener element.
  • the rear end projections 19 are of greater extent than the midpoint projections 20.
  • These rear end projections and midpoint proj ections of each fastener element are received in the respective corresponding interwale grooves 12 on both surfaces of the stringer tape 10 along the longitudinal edge portion 14 thereof.
  • the aforementioned filletshaped element connector 15, arranged longitudinally of the stringer tape to carry the fastener elements 13 at preassigned pitch spacings, are received in the same interwale grooves 12 as the midpoint projections 20. It should be noted that these element connectors are buried in the respective interwale grooves lower than the outer surfaces of the wales l1 and are retained therein by the midpoint projections of the respective fastener elements.
  • the fillet-shaped element connectors are thus protected against damage or ready wear from contact with other objects in the use of the slide fastener incorporating a pair of such stringers.
  • the fastener elements for use in the stringer of this invention can be made of any suitable material by any suitable method. Where plastics is employed, the fastener elements may be formed by injection molding or by extrusion. The fastener elements made of thermoplastic material may also be anchored onto the stringer tape by high frequency or ultrasonic welding.
  • FIGS. 3 and 4 illustrate a modification of the preceding embodiment of the invention, in which there is employed a single fillet-shaped element connector 15 to carry the fastener elements 13 at preassigned spacings.
  • the single element connector 15 is substantially woven into the stringer tape 10 in a staggered fashion so as to alternately interconnect every two adjacent legs 17 (18) or each pitch of the fastener elements on either surface of the stringer tape.
  • Other details of construction substantially follow suit after those set forth in connection with the preceding embodiment of the invention. It will be noted that this element connector 15 is also buried in the interwale grooves 12 of the stringer tape lower than the outer surfaces of the wales 11.
  • each fastener element 13 is of equal extent and are received in the respective corresponding interwale grooves 12 on both surfaces of the stringer tape 10 along the longitudinal edge portion 14 thereof.
  • Pairs of element connectors 15a each in the form of a fabric cord or a plastics monofilament (hereinafter generally referred to as the cord-shaped element connectors) extend transversely through, and are formed substantially integral with, the respective rear end projections 19 and midpoint projections 20 of the fastener elements.
  • These four cord-shaped element connectors 150 are likewise buried in the respective interwale grooves 12 on both surfaces of the stringer tape 10 lower than the outer surfaces of the wales 11.
  • FIG. 6 illustrates still another adaptation of the invention which utilizes a stringer tape 10 having transversely alternating wales 11 and interwale grooves 12 only on one surface thereof.
  • Each fastener element 130 has the inwardly directed rear end projection 19 and midpoint projection 20 formed only on its leg 17, which projections are received in the respective interwale grooves 12 on one surface of the stringer tape 10 along the longitudinal edge portion 14 thereof.
  • a single cordshaped element connector 15a extends transversely through and are formed substantially integral with the rear end projections 19 0f the fastener elements 13a.
  • the cord-shaped element connector 15a is buried in the same interwale groove as the rear end projections 19 lower than the outer surfaces of the wales 1 1.
  • the fastener elements 13a are anchored onto the longitudinal edge portion 14 of the stringer tape 10 by means of stitching 21 extending over depressions 22 formed in the outer surfaces of the legs 17 and 18.
  • each fastener element 13b has the rear end projection 19 and midpoint projection 20 that are received in the respective interwale grooves 12 on one surface of the stringer tape 10.
  • the cord-shaped element connector 15a extending transversely through and formed substantially integral with the respective projections 19 and 20 of the fastener elements, are buried in the respective interwale grooves lower than the outer surfaces of the wales 11.
