## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This patent application is a continuation-in-part of U.S. patent application Ser. No. 12/325,037 filed on Nov. 28, 2008, and entitled “Mechanical Zipper Assist,” which claims the benefit of U.S. Provisional Patent Application Ser. No. 60/990,707 filed on Nov. 28, 2007 and entitled “Dr. V's Hose Helper,” now abandoned, the disclosures of which are incorporated by reference herein in their entirety and made part of the present U.S. utility patent application for all purposes.


BACKGROUND OF THE INVENTION
The described invention relates generally to closure systems for use with garments and the like, and more specifically to a zipper system that includes a plurality of zippers which have been modified to allow a user to easily close the zipper on a garment by using only one hand.
Countless devices contain fasteners, of which one popular type is a zipper. A typical zipper includes a track or chain having two rows of teeth that interlock or mate with each other. A zipper slider is located on the track so that a user can pull on a pull tab on the zipper slider in order to move the slider up and down the track, thereby causing the teeth to open and close to form a chain as desired. A drawback in the current zipper systems is that if any pressure or tension is needed to close the zipper a person must use two hands or have assistance from another person to obtain adequate compressive force to close the zipper.
Therefore, while various devices are known in the art for fastening or closing together cloth or garments, a need still exists in the art for a zipper system that is easy to use, especially with only one hand.

FIG. 1 illustrates a first exemplary embodiment of zipper system 10. Zipper system 10 includes first track 13 and second track 14, wherein each track comprises a row of fasteners or teeth 15 that are adapted to mate or that are mate-able with each other to form a closed chain 34. Fasteners/teeth 15 of zipper system 10 can be made of any type of material commonly used to make zippers, such as metal, plastic, nylon and combinations thereof. Zipper system 10 further comprises a plurality of sliders: first slider 6, second slider 11, and third slider 2, that are adapted to move along the tracks of zipper system 10. First slider 6 further includes a first pull tab 8 connected thereto. First pull tab 8 is further connected to a first pull tab extender 18. First pull tab extender 18 further includes a linking portion 23 and ring portion 27. Second slider 11 further includes a second pull tab 12 connected thereto. Second pull tab 12 is further connected to a second pull tab extender 20. Second pull tab extender 20 further includes a linking portion 25 and a ring portion 28. First slider 6 is adapted to move or slide over teeth 15 of first track 13 and second slider 11 is adapted to move or slide over teeth 15 of second track 14 to provide adequate compressive force for zipper system 10 to close. Third slider 2, located between first and second sliders 6 and 11, further includes a pull tab 4 and can optionally include a joining ring 22. Third slider 2 cooperates and moves or slides along teeth 15 of both first track 13 and second track 14 and causes teeth 15 of both tracks 13 and 14 to mate to form closed chain 34. Zipper system 10 further comprises a connector 16 that joins the plurality of sliders 2, 6, and 11 to allow a user to advance the plurality of sliders along teeth 15 of tracks 13, 14 using only one hand. As shown in FIG. 1, connector 16 operates to link third slider 2 with first and second sliders 6 and 11.
Pull tab extenders 18 and 20 can be made from any material that will allow upward force to be applied by the user. Pull tab extenders can be made from any suitable durable material known, such as, for example plastic, nylon, metal, or the like. Optionally, first pull tab 8 and first pull tab extender 18 can be integrally formed as one piece, and also integrally formed with first slider 6 as one continuous piece. Optionally, second pull tab 12 and second pull tab extender 20 can be integrally formed as one piece, and also integrally formed with second slider 11 as one continuous piece.
To use zipper system 10, a person would thread a finger through rings 27 and 28 of pull tab extenders 18 and 20 and use an upward pulling motion or force to close zipper system 10. The combination of the pull tab extenders coupled with the connector 16 that attaches sliders 2, 6, and 11, allows a user to apply enough force to enable first slider 6 and second slider 11 to advance along teeth 15 of each respective track 13 and 14 while also pulling third slider 2, thereby causing teeth 15 of first track 13 and second track 14 to mate without having to use a second (or even third) hand to apply adequate compressive force to allow the zipper system 10 to close.
Zipper system 10 is typically integrated into a garment 30. In an exemplary embodiment, zipper tape 32 is sewn into garment 30. Zipper tape 32 can be made from any natural or synthetic material or combination of natural and synthetic materials, such as, for example cotton, nylon, polyester, and combinations thereof. Zipper tape 32 further provides bottom stop 36 for zipper system 10 to prevent the sliders 2, 6, and 11 from detaching from the tracks 13, and 14 when the zipper system 10 is fully opened. Garment 30 can be made from any type of synthetic or natural material, such as cotton, polyester, nylon, spandex, or any combinations of natural or synthetic materials. Zipper system 10 works well with garments and material that are elastic in nature and require adequate inward force to allow teeth 15 to mate and form closed chain 34.
As shown in FIG. 1, zipper system 10 may also contain a protective sleeve or sheet of material 50 that prevents the user's skin or hair from getting caught in teeth 15. Protective sheet 50 is usually found at the bottom or starting point of zipper system 10, but protective sheet 50 may run the whole length of zipper system 10. Protective sheet 50 may be sewn into zipper system 10 or formed integrally with zipper system 10.

Garment 130 can be made from any type of synthetic or natural material, such as cotton, polyester, nylon, spandex, or combinations of any natural or synthetic materials. Zipper system 100 works well with garments and material that are elastic in nature and require adequate inward force to allow teeth 115 to mate and form closed chain 134.
Optionally, this first embodiment can be used without pull ring 126 (not shown in the figures). The plurality of extenders may be free strings, cords, or chains made from a suitable durable and tough material known in the art, for example plastic or nylon. To close zipper system 100 user would grasp the ends of the extenders and use upward force to allow the sliders 106 and 110 to travel up the teeth 115 of the tracks 113 and 114, providing sufficient inward compressive force to enable third slider 102 to travel along the teeth 115 of the tracks 113 and 114, causing the teeth 115 of the tracks 113 and 114 to mate and form closed chain 134 zipper system 100. Once the predetermined position is obtained the extenders 116, 118, and 120 are looped under the third slider 102 and top of garment 130 is rolled over the sliders 102, 106, 110 and extenders 116, 118, and 120 to hold zipper system 100 closed, without having to use a slip ring or stopper 122 to keep zipper system 100 closed.
FIGS. 4a-b illustrate a third exemplary embodiment of zipper system 200. In this embodiment, zipper system 200 includes first track 213 and second track 214, wherein each track comprises a row of fasteners or teeth 215 that are mate-able with each to form a closed chain 234. Fasteners or teeth 215 of zipper system 200 can be made of any type of material commonly used in the art to make zippers, such as metal, plastic, nylon and combinations thereof. Zipper system 200 further comprises a plurality of sliders, first slider 206, second slider 210, and third slider 202, that cooperate and slide along teeth 215 of zipper system 200. Third slider 202 is located centrally between the first and second sliders 206, and 210. First slider 206 slides along teeth 215 of first track 213 and second slider 210 slides along teeth 215 of second track 214, to provide adequate traction and grip for zipper system 200. Third slider 202, cooperates and slides along teeth 215 of both first track 213 and second track 214 and causes teeth 215 of both tracks 213 and 214 to mate to form closed chain 234 of zipper system 200.
Zipper system 200 further comprises a connector system 260 that joins the plurality of sliders 202, 206, and 210 to allow a user to advance the plurality of sliders along teeth 215 of tracks 213, 214, using only one hand. Connector system 260 further comprises a plurality of extenders which are further bundled together and attached to pull rings. The plurality of extenders comprises three different extenders 216, 218, and 220 which are attached to the pull tabs 204, 208, and 212 of the sliders 202, 206, 210, respectively, and bundled together by a bundler 262.
