  • Patent number: 10869526
    Abstract: A slidable closure includes a first fastener tape and a second fastener tape and a stabilizing fin. A first row of fastener elements extends along a first fastener tape longitudinal edge. A retainer box is positioned near first fastener tape bottom edge and adjacent a bottom fastener element of the first row of fastener elements. A second row of fastener elements extends along a second fastener tape longitudinal edge and is configured to selectively interlock with the first row of fastener elements. An insertion pin is positioned near the second fastener tape bottom edge. The stabilizing fin is more rigid than the first fastener tape and is substantially planar. The stabilizing fin is coupled with the first fastener tape to extend upwardly from a first fastener tape bottom edge and defines a first edge closest to the first row of fastener elements.

  • Patent number: 9549593
    Abstract: The slide fastener has a separable bottom end stop, and the separable bottom end stop has at least an insert pin and a box pin. The insert pin has an escape portion provided with an inclined surface or a curved surface along which the thickness dimension of the insert pin decreases in the direction of the tape width toward the side edge that faces the box pin, the escape portion being positioned in the front-end corner portion of a first-surface of the insert pin, the corner portion being positioned along the edge that faces the box pin. This allows the escape portion of the insert pin to function as an interference prevention means, efficiently prevent chain failure in an element row when the slide fastener is bent into a U-shape, and maintain stable engaging.

  • Patent number: 7210202
    Abstract: A reverse-separating device for a slide fastener, comprises a retainer pin 5, a separable pin 6 both made of metal and a reverse-separating slider 3. Each of the retainer pin 5 and the separable pin 6 is of a U-shaped cross-section and has a slit 18 formed along its front edge. At the lower end of the slit 18, the retainer pin 5 projects rearward beyond the slit 18 to thus provide a loop-like stopper 22 for engagement with the flange 31 of the reverse-separating slider 3. Once the retainer pin 5 is inserted into the reverse-separating slider 3, the retainer pin 5 is firmly retained by three parts of the reverse-separating slider 3. The separable pin 6 has a projecting ledge 28 formed on the upper end the projecting fin 27 so as to project laterally therefrom. The projecting ledge 28 of the separable pin 6 is adapted to abut against the upper end of the projecting fin 25 of the retainer pin 5 and thus prevent the separable pin 6 from moving further into the reverse-separating slider 3.
