    Abstract: An inclined slope face portion is formed on a top face of a box member. This slope face portion has a downward gradient from a side wall of a box-pin-insertion hole up to a side wall of an insert-pin-insertion hole. The insert pin is inserted into the box member in which the box pin is inserted and fixed in a box-pin-insertion hole thereof. Then, when a rear end portion of a slider is brought into contact with the box member, the slider is inclined relative to the box member. Although conventionally, the insert pin was inserted into the insert-pin-insertion hole of the box member from just above the box member, this invention allows the insert pin to be inserted obliquely from above the box member. Therefore, the insertion operation can be carried out smoothly and easily. Thus, the slider is disposed in an inclined posture relative to a box member of the separable bottom stop assembly so as to achieve a smooth operation for inserting the insert pin.

  • Patent number: 5638585
    Abstract: In a separable slide fastener, a separable bottom-end-stop assembly of synthetic resin is in the form of three-member structure composed of a first pin, a second pin and a box. The first pin has a locking portion. The box has first and second pin insertion bores separated by a central partition having a resilient locked portion engageable with the locking portion of the first pin. The box additionally has on the outer side of the first pin insertion bore a short side wall to be received in a cutout in a bottom end portion of one of opposite fastener stringers. Thus, the firm attachment of the box after sewing can be achieved.

  • Patent number: 5470516
    Abstract: A method of molding a separable bottom stop assembly on a concealed slide fastener, including: forming a number of space portions devoid of fastener elements at predetermined intervals in a concealed slide fastener; impregnating molten synthetic resin in fastener tapes at areas around the space portion; heat-molding and hardening the tapes in such a manner that confronting edge portions of the tapes are turned over; cutting the tapes across the space portion; injection molding a second pin member of the separable bottom stop assembly on the edge portion of one tape and a first pin member of a box member on the edge portion of the other tape at the space portion, contiguously to the fastener elements; and attaching a box to the first pin member to complete the box member. The result is that a separable concealed slide fastener, which could not be put to practical use conventionally, can be manufactured simply.

  • Patent number: 5231737
    Abstract: A slide fastener has a pair of longitudinally extending and parallel textile tapes having thickened longitudinal edges that are transversely juxtaposed and formed with throughgoing holes at transversely aligned locations and that are provided with respective longitudinally extending rows of transversely projecting and interleavable coupling teeth. A slider having slots fittable over the edges is displaceable along the edges over the teeth in one longitudinal direction for interleaving the teeth and coupling the tapes together transversely and in the opposite direction for disengaging the teeth from each other and decoupling the tapes from each other. Thickened synthetic-resin reinforcement tabs are integrally molded onto the tapes at the locations of the throughgoing holes and extend thereat transversely up to the edges.

    Abstract: A bottom-end-stop assembly for a slide fastener comprises a pair of intercoupling male and female members of thermoplastic synthetic resin adapted to be molded on adjacent bottom ends of opposed fastener stringers. The male member has an inner longitudinal projection and a pivot pin. The female member has an inner longitudinal groove receptive of the projection, and an inwardly opening support hole receptive of the pivot pin for pivotal movement of the male member. The male member has at least one aperture in the projection so that the stringer tape is clamped between a pair of mold members so as not to become wavy during the molding. The male member also has on opposite surfaces a pair of reinforcing ridges remote from the inner longitudinal side of the male member.
