FIELD OF THE INVENTION
The present invention relates to a system for connecting two materials. More particularly, the present invention relates to a zipper that is configured with an axially bisected slider, including a left-hand side (LHS) and a right-hand side (RHS). Even more particularly, the LHS slider and RHS slider can be configured to attach to a zipper chain without a need for an insertion pin or other traditional mechanism used to insert one side of the zipper chain into the slider.
DESCRIPTION OF RELATED ART
Most zippers are used to connect two materials, including two pieces of fabric, together. To do this, zippers typically require a slider that is connected to a first piece of fabric, leaving the second piece of fabric free to be inserted into the slider through insertion pin. Once the second piece of fabric is inserted into the slider, the zipper can be “zipped,” or pulled up (or in any direction that closes the zipper), thereby connecting the two materials. Unfortunately, this typical configuration can be difficult for young children, older adults, and others who lack manual dexterity.
FIG. 1 is a face-down view of an example of the prior-art. In this drawing, the zipper system includes a top tape 1 (also called right-hand tape), and a bottom tape 13 (also called left-hand tape). Top tape 1 is connected to the first piece of fabric (not shown), while bottom tape 13 is connected to the second piece of fabric (not shown). The connections can be with thread, glue, or any other known method, including being woven integrally into their respective pieces of fabric.
Chain or zipper teeth 6 are in two halves, with each half in fixed contact with each of top tape 1 and bottom tape 13, respectively. The zipper shown in FIG. 1 includes slider 3 that is slidably coupled to one half of chain 6, and thereby coupled to the first piece of fabric. When moved to an extreme lower position, slider 3 is stopped by bottom stop 7. ?
FIG. 2 is a close-up view of one end of a zipper system. When in use, insertion pin 10 is inserted through slider 3 and into retainer box 11 in a way that aligns each half of the zipper chain so that when slider 3 is moved, the two halves of chain 6 are forced together to connect the first piece of fabric to the second piece of fabric.
In both FIGS. 1 and 2, to move slider 3 along chain 6, a user can grasp pull tab (also called a puller) 4, which is connected to slider 3, and is configured to be pulled in one direction or another, colloquially called “up” (the direction in which slider 3 is moved to connect the two halves of chain 6) and “down” (the direction in which slider 3 is moved to separate the connected halves of chain 6).
When the zipper is fully zipped up, slider 3 is found at the end of the zipper chain, and is stopped by top stop 2.
FIGS. 3 and 4 display a perspective view of slider 3 with pull tab 6. FIG. 3 includes slider 3, which is a single piece, with a top piece 21 that includes a hinge connection 23 for pull tab 6, and a bottom 22 connected to top 21. Bottom 22 is typically connected by a physical connection within the interior of slider 3. Slider 3 further includes slider gap 24, which allows slider 3 to slide up and down a zipper chain, but is constrained by the width of the zipper chain which is typically wider than the slider gap 24.
FIG. 4 is a bottom view of slider 3, that includes bottom piece 22, top piece 21, pull tab 6, and slider gap 24.
In both FIGS. 3 and 4, one can see that lower opening 204 is unitary, and is configured to allow inclusion of a both halves of a chain to sit side by side, with one half of the chain inserted using an insertion pin.
FIG. 5 displays the same slider as in FIGS. 3 and 4, and shows upper opening 205. As can be seen in FIG. 5, upper opening 205 is in two halves to accommodate each half of a chain.
FIG.6 shows an upper and lower exploded view of slider 3. As can be seen in this FIG. 6, top piece 301 and bottom piece 302 are unified by splitter 303, situated between and in contact with both top piece 301 and bottom piece 302. As is shown in FIG. 6, splitter 303 is roughly wedge shaped and extends only a portion of the way from one end of splitter 303 to the other end of splitter 303 such that one end of the slider includes two openings, each opening configured to receive a half a zipper chain; the other end of splitter 303 includes a single opening configured to allow the joined halves of the zipper chain to pass through when physically connected to form a single zipper chain.
FIG. 7 is a perspective view of slider 3, from the top, showing top 701, bottom 702, gap 703, and lower opening 704.
As discussed above, users with limited manual dexterity may have trouble using existing zippers. They may have trouble inserting an insertion pin into a slider, or they may have trouble manipulating the pull tab. Thus, a need exists to provide a zipper apparatus that works with many of the existing components of current zippers, but allows for easier use by those with limited manual dexterity.

FIG. 22 displays a perspective view of an embodiment of the invention, in which LHS slider holder 2201 is configured to couple with RHS slider holder 2202 by inserting tab 2204 into slot 2203. In one embodiment, tab 2204 includes a push button spring activated locking pin, 2206, which, when inserted into slot 2213, can extend through, and lock into, pin hold 2205, thus securing the two pieces together to create single slider holder 2207. As in other embodiments, the LHS and RHS slider holders can be manufactured and attached to their respective LHS and RHS sliders, or can be manufactured as a single piece, so that LHS slider holder is formed as part of an LHS slider, and the RHS slider holder is formed as a part of RHS slider. This provides for two pieces to manufacture, rather than four.
A variety of locking mechanisms to hold together the LHS slider holder and the RHS slider holder have been shown. In practice, many different types of connection can be used. For example, in some embodiments, the locking mechanism is a magnet to hold the two pieces together (see FIG. 10, 1005 and 1006). In another embodiment, a magnet is used as part of tab and slot mechanism to help hold the LHS and RHS pieces together. In some embodiments, the LHS and RHS slider holder are found on a front side of LHS and RHS slider, respectively. In other embodiments, the LHS and RHS slider holders are found on the back side of the LHS and RHS slider, respectively. In some embodiments, the LHS slider holder can be located on the RHS slider, and the RHS slider holder can be located on the LHS slider.
