  • Patent number: 8584326
    Abstract: A slider has an upper blade of a slider body having an insert groove of a locking pawl, a temporary engagement portion which temporary engages and fixes the locking pawl, and a claw hole. The temporary engagement portion is adapted so that, with the locking pawl fixed in position, the position in height of the upper end of the temporary engagement portion is the same as or lower than that of the upper surface of the upper blade. This prevents the temporary engagement portion from being pressed and crushed when the temporary engagement portion is in contact with the tab and so on. As a result, an automatic stop mechanism of the slider can stably function.

  • Patent number: 7360285
    Abstract: An automatic lock slider 1 for a concealed slide fastener comprises a slider body 3, a locking lever 5 and a knob 11. The locking lever 5 is pivotally mounted on the slider body 3. A locking pawl 53 on one end 55 of the locking lever 5 is urged into a fastener element guide channel 39 of the slider body 3 by a spring 7, to prevent unintentional sliding of the slider 1 along a slide fastener. The knob 11 is attached to a connecting ring 9 through which the locking lever 5 is inserted. When opening or closing the slide fastener, the knob 11 rocks and lifts the locking lever 11 to withdraw the locking pawl 53 from the fastener element guide channel 39, thereby allowing movement of the slider 1 along the slide fastener.
