The present invention relates generally to a slide fastener assembly (e.g., a zipper) for a thin shell garment, and, in particular, to a method of installing a slide fastener assembly in a thin shell garment.
Garment manufacturing processes generally involve the use and assembly of unrefined and semi-finished components. For example, a jacket may include a rear panel, a left front panel, a right front panel, a right sleeve, and a left sleeve. Once those components are combined, various finishing elements, such as linings and fabric trims (i.e., elastic waist bands, piping, collars, and the like), can be installed. Closure trims, including snaps, buttons, and/or zippers, can then be added to the assembled jacket. When a zipper is used as a closure, the zipper is generally first assembled from its constituent components to form a finished zipper assembly prior to installation in the garment. Manufacture of a finished zipper assembly typically involves pre-cutting a length of zipper chain (which is itself an assembly of zipper stringer tapes and zipper teeth), installation of a zipper slider, installation of a top stop, and installation of a bottom stop or a “pin and box” assembly.
Returning to the example of a jacket, a “center-front” zipper is a common closure option to close the front of the jacket. A “center-front” zipper commonly refers to a zipper of a jacket or similar garment that closes (i.e., attaches) the two front panels together (as opposed to other zippers that may be used to close pockets, attach sleeves or hoods or collars, close flaps, and the like). A center-front zipper usually has a pin and box assembly installed on the lower end of the zipper. A top stop may also be installed, although some garment applications dispense with the top stop and instead rely on certain sewing techniques to ensure that the zipper slider cannot be removed from the zipper tape (such as when the zipper slider is pulled to the top of the center-front opening). Center-front jacket zippers typically utilize zipper tapes that are made from a fabric material having at least one fabric layer. The front panels of the jacket, to which the zipper tapes are attached, likewise include at least one fabric layer and often two or more layers. Once the zipper tapes are sewn to the front panels of the jacket, the resulting fabric layer includes at least two (and often more) fabric layers, thereby creating a thickened, bulky area at the center-front of the jacket.
In high-performance jackets, such as those designed for rigorous outdoor activities, cold-weather, and/or water-resistant jackets, the use of conventional zipper assemblies can lead to undesirable consequences. For instance, in certain types of jackets, the presence of two or more fabric layers at the center-front opening creates undesirable bulkiness in the jacket at the zipper attachment part of the front panels. Bulkiness adds unnecessary weight to high-performance jackets that often utilize a “thin shell” material that provides superior cold weather insulation. Furthermore, in waterproof or water-resistant jackets, the use of zippers with traditional fabric-based zipper tapes can compromise the water-resistant aspect of the jacket. In particular, if conventional zippers are used in a waterproof or water-resistant jacket, water can penetrate the jacket by passing through the zipper tapes, the sewing thread used to affix the zipper tapes, and/or the zipper teeth.
Garment manufacturers utilize a variety of known solutions to help mitigate the risk of water penetrating a jacket designed to be water-resistant. One option involves the use of flaps attached to one or both of the front panels that extend over and cover the zipper. Unfortunately, however, the use of flaps has limited effectiveness as flaps tend to move while the jacket is worn, do not close securely, tend to allow moisture to come into contact with the zipper, and tend to interfere with manipulation of the zipper slider along the zipper. In addition, flaps add considerable bulkiness to the front of a jacket.
Another known solution for mitigating the risk of water penetration involves the use of zipper tapes that, themselves, exhibit water-resistant qualities. Water-resistant zipper tapes can be used alone or in combination with flaps to help mitigate the risk of water penetration, but neither solution reduces bulkiness arising from multiple layers of fabric material at the center-front opening of the jacket. In addition, applying a water-resistant film or coating to the zipper tapes makes the zipper assembly much less flexible.
Yet another known solution for mitigating the risk of water penetration involves attempting to minimize the “grin” of the zipper (i.e., the gap between the inner edges of the zipper tapes), thereby minimizing the area that water can penetrate. When using a narrow grin, the preferred zipper type is an invisible coil-type zipper, which is typically installed in the garment with the coil teeth facing inward (toward the wearer and away from the weather). However, in order for such a zipper to be operable, some portion of the zipper tape must remain exposed to the weather (because installing the zipper with the jacket panel or flaps completely covering the zipper tape would interfere with operation of the zipper slider).
Accordingly, a need exists for a way to install a slide fastener assembly on a thin shell garment that reduces bulkiness and/or reduces vulnerability of the slide fastener assembly to water penetration. This, and other needs, is addressed by one or more aspects of the present invention.
Some exemplary embodiments of the present invention may overcome one or more of the above disadvantages and other disadvantages not described above, but the present invention is not required to overcome any particular disadvantage described above, and some exemplary embodiments of the present invention may not overcome any of the disadvantages described above.
Broadly defined, the present invention according to one aspect includes a method of preparing a semi-finished slide fastener assembly for installation in a thin shell garment. The method includes: providing a slide fastener chain comprised of two interlocked rows of teeth, each row of teeth being attached to a cord bundle of a respective slide fastener tape; removing the interlocked rows of teeth from a portion of the slide fastener chain, thereby defining a length of the slide fastener chain without teeth; introducing a reinforcing film to the cord bundles, at a location along the length of the slide fastener chain without teeth, to shape the cord bundles for accommodation of a pin and box assembly; introducing an aperture into the slide fastener chain, at a film-reinforced location along the length of the slide fastener chain without teeth, to sever the film-reinforced cord bundles; and cutting the slide fastener chain across the aperture, thereby defining a semi-finished slide fastener assembly terminating in a film-reinforced end.
In features of this aspect, the slide fastener chain may be a polyester coil-type zipper chain; the reinforcing film may include an adhesive; the portion of the slide fastener chain from which the interlocked rows of coil-type teeth are removed may be an intermediate portion; and/or introduction of the reinforcing film to the cord bundles may include ultrasonically bonding the reinforcing film to the cord bundles with an ultrasonic horn and an anvil.

Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
Further features, embodiments, and advantages of the present invention will become apparent from the following detailed description with reference to the drawings, wherein:
As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.
Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.
Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.
Regarding applicability of 35 U.S.C. § 112, ¶6, no claim element is intended to be read in accordance with this statutory provision unless the explicit phrase “means for” or “step for” is actually used in such claim element, whereupon this statutory provision is intended to apply in the interpretation of such claim element.
Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”
When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers,” “a picnic basket having crackers without cheese,” and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”
Referring now to the drawings, in which like numerals represent like components throughout the several views, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
The slide fastener assembly 110 and the methods described herein for installing the slide fastener assembly 110 are particularly well-suited for implementation in high-performance garments, jackets, and the like. In contemplated embodiments, the slide fastener assembly 110 and the installation methods described herein are implemented in “thin shell” garments. Thin shell garments are generally used as an outer layer to shield the wearer from effects of the environment, including wind and water. Thin shell garments are generally made from a thin fabric-based or synthetic material (often comprised of a single layer) and can be used in conjunction with other layers (e.g., an insulating layer) to protect the wearer.
It is contemplated that the slide fastener tapes 115,116 of the slide fastener assembly 110 can be made from an ultra-thin material. In this regard, the slide fastener tapes 115,116 do not contribute much additional thickness when the tapes are bonded to the thin shell garment. With reference to

Additionally, it is contemplated that, after cutting the continuous length of slide fastener chain 140 at the film-reinforced gapped section thereof, each cut piece may, itself, be used as a semi-finished slide fastener assembly 150. In other words, once the cut has been made, one end of each resulting piece terminates at a film-reinforced end, and each resulting piece can be processed separately as a semi-finished slide fastener assembly 150, as described hereinbelow.
The thin-film adhesive 120 can be applied as a layer of generally uniform thickness to the reverse side of the slide fastener tapes 115,116 at or adjacent to the film-reinforced end of the semi-finished slide fastener assembly 150. In a contemplated embodiment, the thin-film adhesive 120 can be applied over the top of an outer reinforcing film that has been applied to the reverse side of at least a portion of the slide fastener tapes 115,116.
With reference to
It is further contemplated that the semi-finished slide fastener assembly 150 can be bonded to the garment by a variety of other means. For example, in some embodiments, it is contemplated that the semi-finished slide fastener assembly 150 can be sewn to the garment panels.
As further shown in

With reference to
Optionally, and with reference to
In another contemplated embodiment, a top stop 148 can be installed on one or both of the slide fastener tapes 115,116 earlier in the assembly process. In particular, it is contemplated that a top stop 148, such as that which is depicted in
Following the steps described in
The methods of the present invention allow a semi-finished slide fastener assembly to be incorporated into a garment by adhesive or other bonding means or sewing. In accordance with the methods of the present invention, a semi-finished slide fastener assembly that is assembled away from the garment can be completed by adding a slider body and a pin and box assembly after the semi-finished slide fastener assembly is adhered to a garment. Additionally, a slide fastener assembly with ultra-thin slide fastener tapes that is installed in accordance with the methods of the present invention can enhance water-resistant aspects of the garment and help to minimize bulkiness. As can now be appreciated, a slide fastener assembly installed in accordance with the present invention can be opened and closed with relative ease, and can maintain a very narrow grin between the adjacent edges of the front panels of the garment in order to enhance the water-resistant capability of the finished garment.
Based on the foregoing information, it will be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application. Many embodiments and adaptations of the present invention other than those specifically described herein, as well as many variations, modifications, and equivalent arrangements, will be apparent from or reasonably suggested by the present invention and the foregoing descriptions thereof, without departing from the substance or scope of the present invention.
Accordingly, while the present invention has been described herein in detail in relation to one or more preferred embodiments, it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for the purpose of providing a full and enabling disclosure of the invention. The foregoing disclosure is not intended to be construed to limit the present invention or otherwise exclude any such other embodiments, adaptations, variations, modifications or equivalent arrangements; the present invention being limited only by the claims appended hereto and the equivalents thereof.
