Definitions

  • This invention relates to a slide fastener and more particularly to a separable type of slide fastener having a separable bottom end connection.
  • separable slide fasteners have been proposed for use on articles such as rain coats, anoraks, bags and the like.
  • a separable fastener is provided with a separable end assembly at one of its tape ends that allows the fastener to split apart at that end for the intended purpose.
  • the end assembly takes the form of a pin member on one stringer and a socket member on the other stringer, both members being releasably interengageable to couple the stringers.
  • the ends of the stringer tapes which are usually woven or knitted, are reinforced in the region of the separable assembly with a suitable reinforcement strip of fabric or plastic film so as to ensure firm attachment of the fastener to the article and also to facilitate the manipulation of the end assembly.
  • the present invention seeks to provide a separable slide fastener having stringer tapes made of thread-free materials which are reinforced against rupture of the chain of coupling elements or damage to the tape whithout any need to fold the longitudinal edges.
  • the separable slide fastener of the present invention comprises a pair of stringer tapes made of a pliable thread-free material, rows of coupling elements mounted on the respective tapes along inner longitudinal edges thereof and a slider adapted to bring said rows of coupling elements into and out of engagement.
  • a separable end assembly composed of a socket member attached to the bottom end of one stringer tape and a pin member attached to the bottom end of the other stringer tape, the socket and pin members being releasably interengageable.
  • reinforcement strips are applied to both stringer tapes at the confronting respective longitudinal edges, only on the underlying surface of the marginal inner edges, only on the underlying surface of the marginal inner edge of said tapes, the length of the reinforcement strips being such that it underlies said end assembly and at least an endmost coupling element located next to said end assembly thus extending beyond the exposed end of said pin member so as to protect the tape portions adjacent to the end assembly against damage.
  • FIG. 1 shows a slide fastener 10 which is separable at its bottom end.
  • the fastener 10 comprises a pair of stringer tapes 11 and 12 having confronting longitudinal edges along which the opposed rows of coupling elements 13 and 14 are secured as by sewn seams 15.
  • the rows of coupling elements 13 and 14 are shown for purposes of illustration to be in the form of a continuous helical coil and are sewn through a pair of cords 16, 16 ( Figure 2) to the respective tapes 11 and 12.
  • a slider 17 is mounted astride the confronting edges of the tapes 11 and 12 and it is manipulated at its pull tab 18 to move slidably along the rows of coupling elements 13 and 14 to close or open the identical halves of the slide fastener 10 in the well known manner.
  • the stringer tapes 11 and 12 are made of a thread-free pliable sheet material such as for example vinylchloride, polyester, polyamide and other suitable synthetic resins, or nonwoven fabrics containing synthetic fibers.
  • the tapes 11 and 12 may be therefore conveniently attached by ultrasonic or high-frequency welding to an article made of for example a thermoplastic material.
  • Designated at 19 is a separable end assembly composed of a socket member 20 including integrally formed stud 21 and attached on one stringer tape 11 and a pin member 22 attached on the other stringer tape 12, the socket and pin members being releasably interengageable to couple the fastener halves in a manner well known.
  • the end assembly 19 may be clinched or injection-molded onto the bottom ends of the stringer tapes 11, 12.
  • the socket member 20 may have a slider function, as is well knwon, so as to permit the fastener to open from the reverse direction.
  • a reinforcement strip 23 attached to and extending all way from one end to the other along the lower inner longitudinal marginal surface of each of the tapes 11 and 12 which underlies the row of coupling elements 13, (14).
  • the reinforcement strip 23 is made of an intimate weave of synthetic fibers, a knitted taffeta or a film of synthetic resins.
  • the reinforcement strips 23 when brought together edge to edge have a combined width W1 at least greater than the width W2 of the socket member 20, or preferably greater than the track of the slider 17.
  • the end assembly 19 is mounted astride and envelops the bottom ends of the stringer tapes 11, 12 at the region which includes the rows of elements 13, 14 sewn seams 15, cords 16 and reinforcement strips 23, as shown in Figure 3.
  • the reinforcement strips 23 each have a length greater than that of the end assembly 19 and more specifically extend along the inner confronting edges of the tapes 11, 12 beyond the exposed ends 21' and 22' of the stud 21 and the pin 22, respectively that adjoin the rows of elements 13, 14, so as to protect the tape portions adjacent to the end assembly 19 against damage which would otherwise result from repeated handling of pin 22 and socket 20.
  • Figure 4 illustrates a modified embodiment in which a pair of reinforcement strips 23a, 23a are applied only to the tape end portions where the end assembly 19 is located, instead of the strips 23 extending along the entire length of the fastener as embodied in Figure 1.
  • Figures 5 and 6 illustrate a further modification which is substantially the same as the embodiment of Figure 1, except that there is provided a reinforcement strip 23' extending transversely of and wrapping around both sides of the tape 13, (14) at the region of the end assembly 19, so as to provide increased strength at that tape region.
  • the present invention is not limited to the use of coupling elements in the form of a continuous helical coil. On the contrary, the invention can be used in the same way with discrete coupling elements, said individual elements being mounted astride of the confronting edges of the tapes.
