  • 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.
