- The present invention generally relates to a zipper system, and specifically, to flexible closure strips.
- Various closure devices have been utilized to join together and separate pieces of fabric type material. Resilient fasteners, including those having zipper sliders, are well-known in the art. Fastening devices typically include two flexible elongated components having teeth or coils that are forced to interlock and separate by moving a zipper slider along the components. Generally, fasteners of this variety include a pair of flexible closure strips, each extruded from a polymeric resin material in continuous lengths and having an interlocking rib and groove structure. Such structures on each of the pair of flexible closure strips may be similar to one another, locking together in an interference fit. Alternatively, one of the pair of flexible closure strips may have a male interlocking member, while the other of the pair may have a female interlocking member into which the male interlocking member may be snapped in an interference fit. Non-similar strips have one male strip and one female strip. Similar strips are each both male and female/androgynous but not always exactly alike.
- Resilient fasteners of either of these two of the flexible closure strips may be opened and closed with a zipper slider when pulled in one direction, and separating them when being pulled in the opposite direction.
- According to an embodiment of the present invention, there is disclosed a zipper system characterized by at least a first zipper strip having a profile/interconnection portion and tape extending the length of the zipper strip. The at least a first strip is constructed of more than one material selected from the group comprising materials that are rigid, semi-rigid, flexible, and semi-flexible. The zipper system comprises at least a first strip having at least a second strip similar to it.
- The structure, operation, and advantages of the present invention will become further apparent upon consideration of the following description taken in conjunction with the accompanying figures (FIGs.). The figures are intended to be illustrative, not limiting. Certain elements in some of the figures may be omitted, or illustrated not-to-scale, for illustrative clarity. The cross-sectional views may be in the form of “slices”, or “near-sighted” cross-sectional views, omitting certain background lines which would otherwise be visible in a “true” cross-sectional view, for illustrative clarity.
- In the drawings accompanying the description that follows, both reference numerals and legends (labels, text descriptions) may be used to identify elements. If legends are provided, they are intended merely as an aid to the reader, and should not in any way be interpreted as limiting.

- Slide fasteners, commonly known as zippers, have long been known to be useful for the opening and closing of two adjoining pieces of material, such as a fabric type material. A traditional zipper is typically composed of a tracking base or tape made of substantially equal size portions of material, such as a fabric type material on either side, a series of teeth or coils that interlock upon closing and unlock upon opening that is attached to the tracking base, and a sliding means for opening and closing the interlocking teeth that are attached to each track that contains the interlocking teeth. However, traditional zippers have an inherent mechanical weakness due to the fact that their zipper strip is comprised of two series of tiny teeth or coils on a tracking base that interlock with one another by a force caused by pulling the two series of tiny teeth or coils of interlocking teeth toward each other when a sliding device is moved along the length of the tracking base. An opposite force is created when the two series of tiny teeth or coils on the two equal size portions of material, such as a fabric type material on the tracking base are pulled away from each, such as when the zipper is on a full suitcase that is being forced to close. Therefore, traditional zippers have an inherent weakness when they are stressed as they are stressed and pulled, interlocked and unlocked in the same force component. This makes for a very weak joint.
- The improved zipper system 10
strip 12 utilizes a novel orientation and attachment of twozipper tapes zipper strip 12. The twotapes zipper strip 12, seeFIG. 5 , are mounted to separate portions of material, such as afabric type material strips 12 of zipper, redirects the forces on the zipper system 10 out of the plane of thezipper strip 12, so that the zipper system is stressed and pulled in a different force component than it is interlocked and unlocked thereby causing less wear and breaks than the typical prior art zipper systems. Each of thestrips 12 may or may not be provided independently of the other. The improved zipper 10 is designed to operate smoothly and reduce the friction commonly found with traditional zippers. -
FIG. 1 illustrates an improved zipper system 10 mounted to separate portions of material, such as afabric type material strips 12 that may or may not be interconnected to seal the zipper system into a closed condition, as shown inFIG. 5 . Thestrips 12 are similar to one another because they are each both male and female strips. The improved zipper system 10 is configured such that the twostrips 12 may or may not be opened and closed to form the sealed zipper. - The core 18 is comprised of one or more generally
U-shaped bodies 16 that may or may not be interconnected to each other. It is also within the scope of the invention to include a wire carrier, a section ofwebbing 17 or to dispense the wire carrier with a section ofwebbing 17 to reinforce the tape and profile of the twostrips 12. The generallyU-shaped bodies 16 have twoside walls bottom wall 16 c. The generallyU-shaped bodies 16 are typically constructed of metal and may have any desirable dimensions. There may be any desirable number of individual generallyU-shaped bodies 16, generally determined by the length ofzipper strip 12. It is within the terms of the embodiment that the generallyU-shaped bodies 16 be made of wire that is not segmented. Further, it should be noted that the twostrips 12 needn't incorporate a generally U-shaped core or a webbing. -
FIG. 2 illustrates a detailed view of the core 18 of thestrip 12. Althoughstrip 12 is illustrated, it should be noted that the twostrips 12 are similar because both have the same generally U-shape which is an androgynous shape. - The generally
U-shaped bodies 16 are connected, although they may or may not be adapted to be easily removable or broken away from each other. As shown inFIGS. 2 and 3 , upon each of the first andsecond side walls protruding connectors protruding connectors connectors 18 a on each generallyU-shaped body 16 are attached to theconnector 18 a on an adjacent connector and theconnectors 18 b protruding from each generally U-shaped body are attached to theconnectors 18 b protruding from an adjacent generally U-shaped body. The linkage of thesesmall connectors U-shaped bodies 16 are connected, the bond therebetween is not overly rigid. This is due to the relatively small surface area of eachconnector bottom wall 16 c though they are not shown. There may be any number of protruding connectors including zero protruding connectors since the generally U-shaped bodies may not be interconnected to each other. - The section of
webbing 17 project outward from the twostrips 12 and are attached to the separate portions of material, such as afabric type material FIG. 1 , adjacent to the location where the twostrips 12 are to be opened or closed. Generally, thewebbing portion 17 and core covering 24 are attached to the material by either a mechanical attachment method such as stitching or a heat attachment method such as a welding method or a chemical attachment method such as applying an adhesive.Webbing 17 includes a plurality ofparallel rows unconnected grooves 22. There may be any desirable number ofgrooves 22 in thewebbing 17. - The upper ends 16 d of the first and
second side walls grooves 22, thereby freely mounting the interconnecting generallyU-shaped bodies 16 to a desiredrow 20 d of the grooves. Althoughrow 20 d of the grooves is illustrated as being engaged to the interconnecting generallyU-shaped bodies 16, any of the desired rows 20 a-20 d may be secured to the interconnecting generallyU-shaped bodies 16. -
FIG. 3 illustrates a detailed, cross-sectional view of the interconnecting portion 11 including core 18 covered by the core covering 24 of the strip ofzipper 12. The core covering 24 extends over and encases the core 18 to form the strips ofzipper 12. Note that inFIG. 3 the arrow to the core 18 indicates that thewebbing 17 is part of the core 18 just asFIG. 2 shows the generallyU-shaped body 16 is part of the core 18. The core covering 24 may be constructed of any suitable material, such as a temperature resistant material, such as a high temperature resistant film, a polymeric or elastomeric material, a woven material, and/or a non-woven material. The core covering/ may have a coating comprised of a material selected from the group consisting of polymer such as a laminate, film, paint, print, or fabric. - The core covering 24 extends over both the interconnecting generally
U-shaped bodies 16, and the portion ofwebbing 17. The core covering portion 26 envelops the interior and exterior of the generallyU-shaped bodies 16. Theinterior slot 26 a of the core covering portion 26 forms an interlockingportion 28 that is typically formed tworibs sidewall 16 b and opposite facingribs sidewall 16 a of the twoside walls U-shaped body 16. The interlockingportion 28 is formed within the twoside walls bottom wall 26 c. The interlockingportion 28 is designed to allow the two strips ofzipper 12 to engage to one another as seen inFIG. 5 . There may be any number of ribs and channels including zero ribs and channels. - As seen in
