Definitions

  • the present invention relates generally to fastening devices, and more particularly to a detachable two way zipper.
  • zipper was popularized by the B.F. Goodrich Company when they used SundbScks fastener on a new type of rubber boots. For nearly twenty years, the zipper was used primarily for rubber boots and closures on tobacco pouches. It was not until the 1930's that the zipper became popular on garments. Today the zipper is by far the most popular fastener. The zipper is found on clothing such as jackets, luggage, bags, camping equipment, and many other objects. Zippers can be found on all types of clothing such as pants, dresses, and jackets, on carriers such as bags and luggage, and in gear such as sleeping bags and tents. In addition to serving as decoration, zippers can join together two sides of a garment, such as in the operation of a dress, and can serve as means to removably atach two pieces of fabric, such as in the attachment of a removable hood to a jacket.
  • Fastening devices such as zippers can be separating or non-separating, and can be oneway or two-way devices.
  • a separating zipper each of the two zipper tracks, comprising the tape and attached teeth, are connected to different elements that are primarily joined only by the interlocking zipper teeth.
  • a non-separating zipper both zipper tracks are connected to a single element such that interlocking and unlocking the zipper teeth creates an opening in that element.
  • a two-way zipper comprises two slider bodies that can work together or separately to interlock and unlock the zipper teeth.
  • a one-way zipper comprises a single slider body as well as a pin and box assembly that aligns the zipper teeth contained on at least one of the zipper tracks.
  • one-way separating zippers are composed of relatively few parts, including: an origination assembly with a pin and a retainer body at the lowerrangt of each row of zipper teeth; two pieces of tape that are attached to fabric on one side and contain zipper teeth on the other; a slider body with a pull-tab; and two top stops at the upper limit of each row of teeth.
  • the operator inserts the pin from the lower limit of one row of teeth into the retainer box at the matching lower limit of the other row of teeth. This aligns the teeth into an operable interlocking format. Once aligned, the operator pulls the latching mechanism, called the slider body, along the teeth track. Wedges inside the slider body force the teeth of each track to interact. If the teeth are aligned, the hook of each tooth settles into the hollow of an opposing tooth. The operator can continue to pull the slider body and interlock the teeth until the slider terminates at the top stops located at the upper limit of eac h row of teeth.
  • a two way zipper allows the user to open or close the garment, bag, or other such Item from either end, thus providing both convenience as well as a closure that can be readily modified in size.
  • a long jacket or coat may be restrictive toward the bottom with the zipper fully closed. It would provide both convenience and comfort to allow the zipper to partially open at the bottom while still maintaining a closed state toward the top.
  • Such an arrangement would allow for -flexibility of movement, ease of access to inner garments or stored items, and generally make for a convenient and comfortable arrangement that can be readily changed to suit the needs of the wearer.
  • a two way zipper on a bag or luggage item would allow a user to partially open the item without the necessity of long zipper travel. While such two way zippers exist they can still be difficult to operate when a user desires to fully open the garment, bag or other such item. In order to place such a zipper in an open or released state, the user must travel the zipper entirely to one end, which can be inconvenient, particularly with longer two way zippers. The ability to fully release a two way zipper at any point of closure would be extremely useful, although such a novel arrangement has heretofore not existed.
  • a Detachable Two Way Zipper 1'he Detachable Two Way Zipper comprises a lower slider having a lower slider base part and a lower slider rotating body; an upper slider having an upper slider base part and an upper slider rotating body; an insertable zipper tape traversing the lower slider base part and the upper slider base part; a fixed zipper tape traversing the lower slider base part and the upper slider base part; the lower slider rotating body and the upper slider rotating body configured to releasably connect; wherein rotation of the connected lower slider rotating body and upper sl ider rotating body causes the first zipper tape and the second zipper tape to separate.
