1. Field of the Invention
This invention relates to zipper repair tools and particularly to hand-held, pliers-like zipper repair tool.
2. Description of the Prior Art
Zippers have been used for well over 100 years. A typical zipper has a pair of strips that have teeth that are interlocked together in a guide as the guide passes over the teeth. The guide has a pair of grooves in which the teeth segments slide to facilitate interlocking. If the guide is damaged, the zipper will not work. Guides can be damaged, or if either side of the zipper guide is not symmetrical in relation to the other side, the zipper teeth will not properly mesh to ensure proper closure. For example, if the grooves are compressed to where the teeth can no longer enter the grooves, the zipper will not work. The more prevalent problem, however, is when the grooves are spread or distorted so that the teeth are no longer held in proper alignment within the grooves. Often, people may try to close the grooves using a tool like pliers to push the grooves closed. The problem with this approach is that it gives the user no control over the adjustment of the groove in relation to each other. It is easy to squeeze the groove too much on one side and thus completely distort the guide assembly. If the grooves are compressed too much, they must be opened again by prying them apart. Often this is done using a screwdriver or a similar tool. As before, there is no control on how much the grooves will be opened. Moreover, excessive force can cause the grooves to break. Finally, there is no simple way to ensure that the grooves are symmetrical and uniform using this technique. Thus, the job becomes a frustrating exercise in futility.
The instant invention is a hand tool that has a pliers-like body and a special head. The head has a pair of parallel teeth that fit onto the lands above the grooves of a zipper guide. As the tool is squeezed, the jaws force the grooves lands down and closed uniformly and symmetrically. Appropriate pressure is applies to set the closure for the zipper teeth. In this way, the tool can work the groove lands on all types of zippers quickly and easily, such as those found on tents, clothing, tote bags, luggage and many other things.

Unlike a standard pair of pliers, which has a gripping head, the head 3 of the instant invention has a pair of parallel jaws 4 that are designed to fit onto the grooves 101 of a zipper guide (see FIG. 5). The head 3 has a right side 3a and a left side 3b that are formed on the top of the handles 2a and 2b as shown.

Note that the heads 3 and jaws 4 of the device are parallel and symmetrical. This allows the user to fit the tool onto all sides of a damaged zipper guide simultaneously, which result in a repair made in one operation. This eliminates the need to adjust one side at a time. Moreover, it eliminates the problem of unbalanced adjustments, which require multiple adjustments to correct.
