Having Specific Mounting Connection Or Reinforcing Structure At Connection Patents (Class 24/434)
  • Patent number: 4571784
    Abstract: A separable bottom-end-stop assembly of thermoplastic synthetic resin, for a separable slide fastener, comprises a pair of first and second separate pin members, and a socket member for being secured to the first pin member, the socket member having a pair of first and second bores receptive of the first and second pin members, respectively. The first pin member has on its opposite faces a pair of recesses, and the socket member has a pair of opposed projections extending into the first bore. In assembling, the projections of the socket member are received in the respective recesses of the first pin member when the latter is inserted into the socket member's first bore. Because of this projection-and-recess locking, the first pin member can be kept exactly in position relative to the socket member while these two members are joined together by fusing.

  • Patent number: 4539733
    Abstract: A separable slide fastener comprises a pair of stringer tapes each carrying on its inner longitudinal margins a row of coiled filamentary coupling elements sewn to the respective inner tape margin with a core thread extending through each of the coiled coupling element rows, and a separable bottom-end-stop assembly mounted adjacent to the bottom ends of the opposed tapes. The bottom-end-stop assembly includes a pair of separate pin members attached by clinching to the respective inner tape margins at bottom end portions thereof, which portions are devoid of coupling elements, and a socket member secured to one of the pin members and having a bore for receiving a portion of the other pin member. Each of the other pin member has a longitudinal channel receiving the element-free bottom end portion of the respective inner tape-margin. Before attachment of the pin members, the bottom end portion of each inner tape-margin is trimmed or shaped along its inner edge that projects inwardly from the core thread.

  • Patent number: 4536923
    Abstract: The invention is an improvement of a separable slide fastener with fastener elements which interlock when brought together perpendicularly to the plane of the fastener, the fastener comprising a retainer pin secured to the tape of one of the stringers and connected to a retainer and a separable pin secured to the tape of the other stringer and removably received in the retainer. According to the invention, at least the separable pin is made flexible by forming a thin portion at an intermediate portion of the pin. Because the separable pin is flexible, twisting of the fastener near the retainer and separable pins is greatly reduced and the separable pin may be very easily inserted in the retainer.

  • Patent number: 4505009
    Abstract: An improved separable slide fastener of the type including a pair of fastener stringers, a pair of male and female members and a box, said male and female members and said box constituting a separator, is disclosed. Each of the female member and the male member includes at least one notch-shaped pawl which is bent inwardly of the rear surface to extend through the fastener tape until it reach to cut in the core cord whereby it is fixedly secured to the lower end part of the fastener stringer. At least one notch-shaped pawl is bent inwardly of the rear surface of the box and extends through the rear surface of the female member and the associated fastener tape whereby the box is fixedly secured to the female member. The box is preferably formed with longitudinally spaced two pawls. The pawls on the female member are formed in the superimposed state relative to the pawls on the box at the same time when the latter are formed.

  • Patent number: 4490890
    Abstract: A separable slide fastener has a pair of warp-knit stringer tapes each with a series of longitudinal openings for easy attachment to a knit fabric. Each of the stringer tapes includes a reinforcing body mounted on a lower end portion thereof and including a thin member and an endmost thick member both extending transversely across some of the tape opening, the thin member covering at least the endmost opening and the endmost thick body having a transverse portion contiguous to the thin member in the longitudinal direction of the stringer tape and extending about a portion of the thin member and the lower end portion of the stringer tape. A separable bottom end stop is injection-molded on the thin reinforcement member bonded to the stringer tape so as to form integrally therewith the thick reinforcement member.

  • Patent number: 4485532
    Abstract: A separable slide fastener comprises a pair of warp-knit stringer tapes each having a pair of webs with a wale-free region therebetween, which are interconnected by a connector thread extending across the wale-free region at longitudinal intervals, the wale-free region being receptive of a chain of thread loops for attaching the stringer tape to a fabric. A pair of rows of coupling elements is mounted on opposite longitudinal edges of the stringer tapes, respectively and taken into and out of interdigitating engagement by a slider movable along the rows of coupling elements. The stringer tapes have at one end thereof a separable bottom end stop. A reinforcement member is mounted on each of the stringer tapes at the one end thereof and connected to the separable bottom end stop.

  • Patent number: 4459723
    Abstract: A slide fastener stringer includes a row of helically coiled or zig-zag coupling elements of thermoplastic synthetic resin with a reinforcing core extending longitudinally therethrough. The coupling elements are secured to one surface of a stringer tape by sewing threads having portions running across and over upper legs of the coupling elements. Some of the coupling elements are cut off to provide an element-free space on the stringer tape. A terminal or endmost complete coupling element disposed adjacent to the element-free space has a free-ended connecting portion remote from a longitudinal edge of the stringer tape. To form an end of the slide fastener stringer, the free-ended connecting end portion of the terminal coupling element is fused to the stringer tape, and at the same time, the upper leg of the terminal coupling element is heated and pressed toward the stringer tape.
