  • Patent number: 8959727
    Abstract: Provided is a slide fastener with a separable bottom end stop having both an automatic stopper and the separable bottom end stop, of which structural components can be used for both left- and right-insertions. In the slide fastener, a stop pawl for the automatic stopper protruding into an element guide passage via a pawl hole is configured to be movable in the lateral direction to an insert pin side and a box pin side. Accordingly, when the insert pin is inserted into the element guide passage through a shoulder opening of a top slider to re-couple separated fastener stringers, the stop pawl can be retreated by the insert pin as being pushed. Accordingly, the insert pin can be smoothly inserted deeply to the top slider with small resistance force. Further, structural components of the slide fastener with the separable bottom end stop can be used for both left- and right-insertions.

    Abstract: A zipper head includes a puller, a horse hook, an elastic piece, a cap and a pulling piece. The puller has guiding grooves there inside and an accommodating portion and a penetrating hole on top thereof. The end portion is disposed under the horse hook. One end of the elastic piece is fixed on the puller. Both sides in the interior of the cap are provided with a protrusion respectively. The two protrusions of the cap are located above the fulcrum portion of the horse hook. Via the above arrangement, a function of blocking and restricting the position of the fulcrum portion of a horse hook can be provided, and thus the fulcrum portion of the horse hook cannot be displaced excessively due to an extreme pulling force of the pulling piece. Therefore, the horse hook can be prevented from getting deformed or deviating from a predetermined position.

Over the pull-tab axle, a locking leaf spring, which has at one end a locking pawl, at the other end a hook and at the center a resilient tongue punched out upwardly so as to form a longitudinal opening, is placed on the upper wing so as that the locking pawl is inserted in the hole while the hook is slidably engaged with the front lug, and that a central projection is loosely inserted through the opening 23. A cover is mounted on the front and rear lugs so as to define a gap between the cover and the front lug. When the spring is moved forwardly, the locking pawl comes into contact with a front wall of the hole, so that the locking pawl can be protected.

  • Patent number: 5848455
    Abstract: In an auto-lock slide fastener slider composed of four members, i.e., a slider body, a pull tab, a locking member and a cover, the slider body has front and rear resilient cover-attachment projections extending from an upper wing and terminating respectively in outwardly directed hooks while the cover is made of thermoplastic resin and has on respective inner edges of front and rear end walls corresponding inwardly directed hook portions resiliently engaged with the hooks of the cover-attachment projections. The cover can be attached to the slider body simply in a single snap action. Since all parts of the attaching mechanism are concealed by the cover, the resulting slider is neat in appearance.

  • Patent number: 5809622
    Abstract: In an autolock slider, an upper wing of a slider body has a concave pivot-projection-receiving recess extending into a fastener-element guide post, a locking-pawl-insertion hole off the guide post, and an attachment post standing on the guide post. A locking lever having at its front and rear ends a pivot projection and a locking pawl, respectively, is supported on the upper wing with a rounded end of the pivot projection loosely received in the concave recess and the locking pawl inserted in the locking-pawl-insertion hole. A spring is accommodated in a spring-accommodating portion formed on the upper side of the attachment post, resiliently touching the upper side of the lever. The attachment post has a tongue for restricting upward movement of the pivot projection.

  • Patent number: 5787689
    Abstract: A bag discharge constriction apparatus and method are disclosed in which the extent to which an opening in a bag is constricted is adjustably varied to control the discharge of material from the bag. The apparatus has a first control bar and a second control bar, each defining at least one angular relationship in a corresponding plane. Also disclosed is a means for moving at least one control bar in its associated plane toward and away from the other control bar. The control bars are disposed in opposing configuration such that the combination of the angular relationships forms a predetermined confined shape between the control bars. It is into this predetermined confined shape that the neck of the bag to be constricted is placed and the bars are then moved toward or away from each other to constrict or open the neck of the bag.

  • Patent number: 5664300
    Abstract: In an auto-lock slider for a slide fastener, each of front and rear attachment lugs on a slider by has a provisional spring-holding ends in the form of a holding projection having in its top a V-shape groove, each lug having on opposite side surfaces a pair of guides and in its outer side base a pair of recesses. In assembly, a leaf spring having in its each end a cutout is placed on the two holding projections, whereupon these projections are clenched, by pressing, to provisionally hold the spring. At that time, a locking lever is supported on e slider body between the lugs to normally urge the locking lever to a slider locking position, and a pintle of a pull tab is disposed between the locking lever and the slider body for bringing the locking lever out of the slider locking position against the resilience of the leaf spring.

  • Patent number: 5625928
    Abstract: In an automatic lock slider for a slide fastener, a yoke accommodating a locking pawl and a leaf spring has a pair of inwardly directed projections, and a generally C-shaped, narrow rigid strip has on its upper edges a pair of taper surfaces corresponding to the respective projections. As the taper surfaces are guided by the projections, the pawl keeps its suitable posture during the assembling of the slider, and the pawl acts reliably while the automatic locking mechanism is either operative or inoperative. The locking pawl is small in width and has one leg portion to be inserted in a groove of the outer surface of a connector of a slider body. The result is that the number of pressing steps is reduced to minimize press traces on the surface of an upper wing of the slider body so that press traces are prevented from coming out on the slider surface though the yoke is smaller in width compared to the conventional one.

  • Patent number: 5603144
    Abstract: In an automatic lock slider for a slide fastener having element rows on its back side, a resilient member having a locking pawl engageable and disengageable with the element rows from the back side is actuated by one end of a pivotal bat pivotable about a pivot, the resilient member being in the form of a small-width metallic leaf spring having a predetermined length and bent in a desired shape. The resilient member keeps adequate resilience for a long period and secures more reliable resilient deformation and restoration compared to a mere leaf spring, so that the locking pawl can come into and out of engagement with the element rows smoothly and reliably, depending on whether or not a pull tab is pulled.
