  • Patent number: 10051927
    Abstract: A zip slider has: a slider body having upper and lower elements providing two entry channels through which zip teeth pass and slider un/mating; a pull tab having a cam; a biasing spring having a locking prong and a follower surface bearing against the cam. The cam on the follower surface biases the tab into a closed position in which it lies against the upper element. When the tab is in a lifted position, the cam action on the follower surface raises the prong above the mated teeth, enabling relative motion of the teeth and body; when the tab is in the closed position, the prong bears against the teeth to prevent unwanted relative slider and teeth motion. The slider has a counter bias, acting between the upper element and the tab to apply a biasing force on the tab acting against the action of the cam and follower surface.

  • 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.

  • Patent number: 7313847
    Abstract: The CTF Flip-N-Zip slider enables the purchasers of a zipper with the CTF Flip-N-Zip slider installed to disconnect at least one side of a zipped zipper and return it to the starting position. Current fixed sliders are very hard to fix if a foreign object jams the zipper or if the zipper opens behind the slider. CTF Flip-N-Zip slider requires only that the owner disengage the lock and remove either the top or bottom plates or half plate depending on the design. This is shown in the drawings for a releasable latch pin of the slider. The owner would then return the zipper to the starting position and reattach and lock the slider and start over using the same slider. Other designs currently in consideration are push button releases, hinged plates with hidden lever, draw activated releases, etc. Sliders will be made to fit all available zippers and zipper materials.

  • Patent number: 6637078
    Abstract: It relates to a slider for slider fastener with locking device where a sheet-like spring having a locking pawl at one end is fixed at the other end on a body. A bent portion of a spring portion of the fixed spring is exposed at a guide post, and a pull is mounted between the body and the spring so as to be raised or laid. A cam is provided on a lower face of an axle of the pull, and the axle slides on an inclined guide portion on the body. When the pull is laid forward of the body, a gap is formed between an edge of a through hole of a grip portion of the pull and the bent portion of the spring. Even if a load is applied to the pull in the horizontal direction or the vertical direction, this gap prevents the spring from plastic deformation, so that the spring is never plastically deformed under any use condition, thereby ensuring an excellent locking function.
