Description

FIELD OF THE INVENTION

This invention relates, generally, to a fastener. More specifically, the invention relates to a garment fastener that improves the fit of a garment on the buttocks of the human body by allowing two separate garment swatches to slidably move with respect to each other as the body moves. The invention is specifically designed to be used with form fitting pants or trousers, such a jeans, but the invention may be used with any fabric or article of clothing, including, but not limited to, denims, capri pants, skorts, slacks, shorts, bathing suits, underwear, and all other types of garments.

BACKGROUND OF THE INVENTION

Although pants for women did not become fashionable until late in the 20th century, currently, pants, and more specifically jeans are commonly worn by women. Indeed jeans have become quite stylish and feminine and are designed to not only cloth the wearer, but to enhance the shape of the wearer's body. Despite the many different styles and types of jeans, no jeans currently available in the marketplace have a seam that allows two parts of the jeans, such as a buttock portions, to slidably move with respect to each other.

There have been developed a wide variety of different assemblies to facilitate the joining of objects or fabric swatches to one to another in the fashion industry. The most common type of permanent fastener in the fashion industry is a stitched seam. The stitched seam is the line where two or more layers of fabric are held together by threads or stitching. The stitched seam allows the clothing manufacturer join two flat swatches of fabric together to create a variety of clothing articles, including those with a form fitting shape.

The stitched seam is designed to securely fasten two swatches of fabric together and it essentially prohibits the two swatches from slidably moving against each other. As such, the swatches joined together by the stitched seam move together like they are the same swatch.

In addition to the permanent fastener of stitching, there are many types of fasteners that are designed to temporarily fasten swatches of fabric together, such as zippers, buckles, buttons, hooks, loops, pins, laces, snaps, and hook and eye. Many of these fasteners use the principle of male to female connection such that a male portion matingly engages with the female portion. However, in addition to the limitation that these fasteners are designed to only temporarily join the two swatches, the vast majority of these fasteners do not allow the swatches to slidably move opposite each other.

Regarding specific references that disclose a female to male connector for use with fabric that may be slidable, U.S. Pat. No. 1,719,856, issued to Sipe, U.S. Pat. No. 1,959,319, also issued to Sipe, U.S. Pat. No. 3,875,623, issued to Johnston, and U.S. Pat. No. 4,939,995, issued to Daus, disclose such a fabric joint connector. Although the above references disclose a fabric joint connector, importantly none of those references are directed towards, or even hint at, a permanent slidable fabric joint connector that replaces where a stitched seam would normally be in order to allow movement in a garment as it is worn by a user.

Regarding references that disclose a male and female rib connector that may be slidable, U.S. Pat. No. 5,187,843, issued to Lynch, disclose such a fastener. However, the Lynch fastener is not a permanent fastener and it is directed at a releasable interconnection of two large objects that are combined to cover an even larger area Importantly, the Lynch fastener is designed to be easily disengagable without sliding the two objects apart.

Despite the long existence of the various connectors and fasteners discussed above, there remains a need for a permanent connector that allows two pieces of fabric to slide opposite to each other and may be used in a pair of form fitting pants to enhance the look of the movement of the buttocks of the wearer.

SUMMARY OF THE INVENTION

To minimize the limitations in the prior art, and to minimize other limitations that will become apparent upon reading and understanding the present specification, the present invention discloses a new and useful fastener device, which permanently fastens two pieces of fabric together but allows the two pieces of fabric to slide in opposite directions with respect to each other.

One embodiment of the invention is a fastener, comprising: a male rib and a female rib. The female rib is inserted into the male rib creating a permanently connected joint. The female rib and the male rib are slidable with respect to each other. Preferably the fastener also includes a male fabric portion and a female fabric portion. The male fabric portion is attached to the male rib and the female fabric portion is attached to the female rib. The fastener may also have a joint cover. The joint cover covers an outside portion of the joint such that the joint appears to be a standard stitched seam. Typically, the fastener is part of a wearable garment, such as a pair of jeans. The joint is preferably used to replace a vertical rear seam on a pair of jeans and the female and male fabric portions cover a buttocks of a garment wearer. The joint has an upper attachment and a lower attachment, which limit the slidable motion of the joint. Preferably the male and female of ribs are made out of plastic or polytetrafluoroethylene, such as Teflon®. The male rib has a rounded arrow shape and the female rib has an open end, which is shaped to accept the rounded arrow shaped male rib.

The fastener may be connected to itself by inserting the male rib into the female rib by pushing the male rib into the female rib such that the female rib widens said male rib and snaps into place. The rounded arrow shaped male rib preferably has one or more rounded back portions that when engaged with the female rib, prevents the male rib from being pulled free of the female rib. The joint allows the female fabric portion and the male fabric portion to move with the buttocks of the garment wearer as the garment wearer moves or walks.

Another embodiment of the invention is a pair of pants, comprising: two rear leg portions; a waist band portion; a male rib; a female rib; and a joint cover. The first of the two rear leg portions is attached to the male rib and the second of the two rear leg portions is attached to the female rib. The male rib is matingly engaged with the female rib forming a rear joint. The female rib and the male rib are slidable with respect to each other. The rear joint connects the two rear leg portions to each other to form a back side of a pair of pants. The rear joint allows the two rear leg portions to move with the buttocks of the garment wearer as the garment wearer moves or walks. The waist band portion conceals the top of the rear joint, the crotch of the garment has an extended flap and opening to allow the movement of the seam at the bottom, and the joint cover covers an outside portion of the rear joint such that the rear joint appears to be a standard stitched seam. Preferably the male rib has a rounded arrow shape and the female rib has an open end, which is shaped to accept the rounded arrow shaped male rib. Preferably the rounded arrow shaped male rib has one or more rounded back portions that when engaged with the female rib prevents the male rib from being pulled free of the female rib. This keeps the ribs permanently connected. The pair of pants is a pair of jeans. The ribs are preferably made out of plastic or polytetrafluoroethylene. The slidable motion is typically limited by an upper attachment and a lower attachment.

It is an object of the invention to overcome the limitations of the prior art.

It is a further object of the invention to provide a garment that slidably moves with the user to enhance the look of the user as he or she walks or moves.

The invention is a slidable joint that replaces a rear vertical seam of a pair of pants (or any other article of clothing) and allows the two buttock portions of the pair of pants or any other types of garment worn on the human buttocks, to slide up and down relative to each other.
