     BACKGROUND OF THE INVENTION 
       [0002]    A. Field of the Invention 
         [0003]    Embodiments of the present invention generally relate to fabric venting mechanisms. More particularly, embodiments relate to no-catch mechanisms that prevent a venting mechanism&#39;s integral fastener from catching fabric parts. 
         [0004]    B. Description of the Related Art 
         [0005]    The technical apparel industry is currently enjoying great success in the consumer environment. This may be attributed to a continuous flow of products embodying ever-increasing technical sophistication and customization. In recent years, apparel items such as jackets, shoes, and pants have been customized to fit a great number of activities (e.g., hiking, trail running, distance running). Each of these activities requires its own performance criteria and design considerations. Design considerations also may vary based on upon such criteria as gender, durability, and aesthetics. 
         [0006]    Athletes enjoying outdoor sports are subject to the elements. To counter the elements, these athletes often need specialized technical apparel. The item&#39;s design considerations must be optimized to offer the most protection or relief from the elements, while still allowing the user to maintain high performance standards. 
         [0007]    For example, trail running or hiking is often an all-day or multi-day activity during which the performer may encounter any number of changing weather conditions. A trail runner may utilize a jacket to counter the effects of chilly or rainy conditions. Today, many jackets are waterproofed or wind proofed to keep the trail runner warm and dry. 
         [0008]    However, in addition to aiding the trail runner in remaining warm and dry, waterproofing or wind proofing a jacket inhibits the venting of accumulated body heat. In addition, it may inhibit evaporation of body moisture exuded during physical exercise. Unfortunately, conventional jackets may not be equipped with proper venting mechanisms to counter such accumulation of excess heat and moisture. 
         [0009]    One way to improve the breathability of garments is to provide them with a means to ventilate. Venting mechanisms or ventilation ports typically consist of breathable material, and may be designed into various locations of the item of apparel. The venting mechanisms may be placed in isolated areas critical to relieving heat buildup and countering body moisture collection, and may comprise a fastener to close or open upon need. 
         [0010]    In some embodiments, the ventilation ports may include fabric arrangements (e.g., a mesh arrangement) set underneath an opening and a fastener. The mesh gussets repel the elements when opened, yet allow heat to escape through the perforations in the fabric of the mesh gusset. An exemplary embodiment including common ventilation port placements is shown in  FIG. 1 . In this embodiment, the ventilation ports are placed in the underarm area of the jacket  101  and the outer thigh area of the pants  102 . The mesh gusset  103  is detailed as well. As shown, a zippered ventilation port entry  104  is under a flap in two areas. 
         [0011]    A frequent problem in utilizing a ventilation port mechanism is that the fastener (e.g., a zipper, a hook and loop fastener) often becomes attached (i.e., “catches”) and entangled with the mesh fabric of the ventilation port during opening and closing. This may be inconvenient to those participate in outdoor sports, as it is especially difficult to undo in the heat of performance or competition. This inconvenience may be especially irritating for athletes wearing gloves, as gloves inhibit the dexterity required to correct the problem. In addition, the mesh fabric often tears or rips during forceful attempts to untangle the zipper. 
         [0012]    Attempts were made to overcome this inconvenience. For example, apparel designers attempted to set the mesh fabric back a certain distance from a zipper by utilizing a shell fabric strip or “A” grosgrain ribbon patched over the mesh, fabric just under the zipper. Typically, the center of the mesh fabric still turned inside-out and wandered up through the opening, thereby obstructing the zipper. Designers also added a stitched ⅛″ pin-tuck or pleat down the center of the mesh fabric away from the zipper, resulting in inconsistent success. 
         [0013]    Another attempt consisted of adding layers of cording or fabric strips set under the fastener and bridging across the two sides of the ventilation port. However, these added layers constituted bulk detrimental to those engaged in intensive outdoor sports. In addition, the added layers were also often inadvertently caught in various items, including the fastener.

     DETAILED DESCRIPTION 
       [0018]    Aspects of the present invention relate to a no-catch mechanism that prevents a venting mechanism&#39;s integral fastener from catching fabric parts. Embodiment no-catch mechanisms may comprise an elasticized shock cord set along the interior center length of the mesh gusset on the opposite side of a fastener. An apparatus comprising the no-catch mechanism may be included in significantly different settings and still be within the scope of the present invention. Moreover, the specific configuration of the no-catch mechanism may vary significantly and still be within the scope of the present invention. 
         [0019]      FIG. 2  illustrates an embodiment method for the manufacture of the no-catch mechanism.  FIG. 2   a  illustrates shell fabric facings  201  set and joined along lengthwise edges of the mesh fabric of gusset  202 . Shell fabric facings  201  may be set off a set distance (e.g., ½″) away from the edges of mesh fabric.  FIG. 2   b  illustrates shell fabric facings  201  folded over to meet the edges of mesh fabric.  202 . In  FIG. 2   c , the joined shell fabric facings  201  and mesh fabric  202  are folded “wrong” side to “wrong” side (i.e., in this case, folded toward the bottom), and along the seams. Next, the folded portions are edge-stitched  203  together as shown in  FIG. 2   d . After the edge-stitching is complete, the folded edge-stitched portions are opened back. This is called the “pintuck”. See  FIGS. 2   d  and  2   e.    
         [0020]    Next, a no-catch mechanism is inserted. First, as shown in  FIG. 2   f , the mesh fabric may be folded “right” side to “right” side (i.e., in this case, folded toward the top) and stitched, for example, to house no-catch mechanism  204 . In this embodiment, no-catch mechanism  204  is an elastic cord (i.e., a “bungy” cord or shock cord). As shown in  FIG. 2   g , shock cord  204  may be inserted into the piping generally along the center of the mesh fabric gusset. In  FIG. 2   g , shock cord  204  is stitched closed using piping stitching  206  (as shown by the dotted lines). The piping stitched-shock cord  204  is shown in open form in  FIG. 2   h . When the two folded, edge-stitched pintuck portions are brought together (in a closed form), the shock cord aids in creating an enclosure (i.e., a “tent”) to pull the gusset away from a fastener, such as, for example, zipper  208 . See  FIGS. 2   g  and  2   i . In one embodiment, portions of zipper  208  may be attached to the two folded, edge-stitched pintuck portions (as shown). 
         [0021]    In addition, an enclosure with walls extending outwardly  207  (i.e., an “accordion”) is created by pintucks  203  and piping stitched shockcord  206 , which operate to further distance the mesh fabric from the fastener, and thereby further preventing a fastener catch. 
         [0022]    Various shapes of gussets may be utilized with the no-catch mechanism. For example,  FIG. 3  illustrates a generally oblong shaped (i.e., a “fish-eye”) venting mechanism embodiment comprising a no-catch mechanism. Various views of “fish-eye” shaped mesh gusset  301  are shown in  FIG. 3   a - h.    FIG. 3   a  illustrates mesh gusset  301  before sewing.  FIG. 3   b  illustrates shell fabric facings  302  sewn to the edges of mesh gusset  301 . In  FIG. 3   c , no-catch mechanism  303  is inserted. The mesh fabric is folded right-side to right-side (as shown) and stitched, for example, like piping to house no-catch mechanism  303 .  FIG. 3   d  illustrates a view of the mesh gusset embodiment including shell fabric facings  302  after no-catch mechanism  303  is inserted. In this embodiment, the shell fabric facings (the edges) and set off no-catch mechanism  303  combine to form an opening 
         [0023]      FIG. 3   e  illustrates a top view of an exemplary venting mechanism in closed position.  FIG. 3   f  also illustrates a top view of the venting mechanism with the fastener opened (in this case, a zipper), exposing mesh gusset  301 . No-catch mechanism  303  and shell facings  302  combine to form an opening that generally has an orientation concurrent to an orientation of the zipper fastener. As shown in  FIG. 3F , the zipper fastener may completely surround the venting mechanism when unzipped.  FIG. 3   g  illustrates a top view of the closed venting mechanism and mesh gusset  301 , with no-catch mechanism  303  extending (or tenting) mesh gusset  301  away from the fastener.  FIG. 3   h  illustrates a bottom view of the venting mechanism with no-catch mechanism  303  tenting the mesh fabric away from the fastener and shell facings  302 . In one embodiment, pintucked shock cord  303 _may be also designed to be shorter than the length of the zipper. This may cause shock cord  303  to lean toward one side of zipper  303  opening See  FIG. 3   i.    
         [0024]      FIG. 4  illustrates an alternate gusset embodiment comprising a no-catch venting mechanism with a shape that extends toward the middle (i.e., a “hammock” shape).  FIG. 4   a  illustrates two pieces of mesh gusset  401 , with shell facings  402  sewn to the sides.  FIG. 4   b  illustrates the curved sides of mesh gussets  401  stitched together right side to right side by stitching  403 .  FIG. 4   c  illustrates mesh gussets  401  folded back (as shown). No-catch mechanism  404  is enclosed by stitching  405  along the center of the gusset. Stitching  405  aids in dropping the gusset lower (thereby further preventing a fastener catch), and also aids in ventilation.  FIG. 4   d  illustrates the two pieces of mesh gusset  401 , shell facings  402 , and set off no-catch mechanism  404  combining to form an opening  FIG. 4   e  illustrates the side view of the hammock gusset, with shell facing  402  at top and no-catch mechanism  404  dropping below.  FIG. 4   f  illustrates a cross-section of mesh gusset  401  before being set under the fastener. Shell facings  402  are located under the fastener, and no-catch mechanism  404  pulls mesh gusset  401  away from the fastener. The combination of pin-tucks  406  and no-catch mechanism  404  create the accordion effect of mesh gusset  401 . 
         [0025]    The hammock-shaped gusset  401 , as detailed in  FIG. 4   c , may include a pintucked shock cord  402  that is longer than the length of the fastener (e.g., a zipper). This causes shock cord  402  to drop away from the fastener, thereby preventing a fastener catch. See  FIG. 4   e.
