Definitions

  • I12 core or filler is a tubular structure designed to flexibly [58] yield itself an fit g y into the Coil 'Ofeach element Field of samba/205.1 c, 205.13 "c, 205 16 4 Claims, 2 Drawing Figures 1 SLIDE FASTENER HAVING A FILLING CORE BACKGROUND OF THE INVENTION
  • core or filler is made usually of fibrous or plastic materials and has a solid cross section either circular or square.
  • the conventional core when sewn together with the row of fastener elements or otherwise subjected to pressure load, would serve adversely to cause objectionable deformation of the fastener elements and disturb the loop to loop spacing or pitch in the fastener element row.
  • the core makes a serpentine deflection such that the strength of coupling engagement between each loop of element differs throughout the length of the row of fastener elements and furthermore, the slider movement thereon is rendered extremely heavy at one place and conversely light at another.
  • FIG. 1 is a plan view of a segment of a slide fasteneraccording to the invention.
  • FIG. 2 is a'transverse cross-sectional view taken @1005 the line IIII of FIGI l.
  • a slide fastener whiehee-mprises a pair. of oppositely disposed carrier tapes 11,12 each carrying along one longitudinal inner edge a row of continuous fastener elements E formed into a helical coil structure having successive loops E En interengageable with those on the opposite tape.
  • Each loop is cross-sectionally egg-shaped as seen in FIG. 2 and consists of a coupling head portion Ea, leg portions Eb and a connecting portion Ec as is usual with any known coil fastener element.
  • a reinforcing core 13 which in accordance with the invention has a tubular configuration with a hollow space 14 extending through its entire length.
  • the reinforcing core 13 which constitutes an important feature of the invention .may preferably be made of fibrous yarns knitted into a tubular. form. Such knitted core may be further treated suitably with a synthetic resin. Alternatively, the core 13 may be formed by extrusion of a plastic material into a tubular structure.
  • the advantage of the hollow core 13 according to the invention is that when inserted in the successive loops E En and sewn together therewith to the respective carrier tape 11,(12) as by two-thread chain stitches S as shown, the core 13 can be brought into intimate contact with the internal peripheral surfaces of each loop including the leg portions'Eb and connecting pot.- tions Ec but of course excluding the coupling head portion Ea lest the core 13 should interfere with the space in which adjacent loops engage with each other.
  • the core 13 being hollow and hence resilient can readily yield itself at any given point in response to the sewing pressure or other external load and assumes a crosssectional shape corresponding to the internal space of each loop defined by the leg portions Eb and connecting portions Be. This takes place without imparting stresses to the fastener elements E which would otherwise result in deformed elements or disturbed element.
  • the reinforcing core 13 will thus serve its purpose of retaining the rows of fastener elements-E stably in proper position on the carrier tapes 11,12, enhancing the strength of coupling engagement of the elements E uniformly throughout the length of the fastener, and further facilitating the smooth reciprocal movement of the slider along the rows of elements E.
  • a slide fastener comprising a pair of oppositely disposed carrier tapes, a row of fastener elements formed into a continuous helical coil structure and secured to each of said'tapes, each element having a coupling head portion, leg portions and a connecting portion and a reinforcing core of a hollow tubular structure extending longitudinally through said row of elements in intimate contact with the internal peripheral surfaces of said leg portions and connecting portions of each element.
