INVENTOR OOO GOOOOOOOOOOOOOOO l! Ill United States Patent The present invention relates to zipper fly closures of garments and particularly it has to do with mens trousers and ladies slacks and skirts. The object of the invention is to provide an improved zipper fly closure wherei by the exposure of the zipper elements when the garment is worn is substantially eliminated while superfluity of thickness at the fly closure region is dispensed with.

The invention will be clearly understood when the following description is read in connection with the accompanying drawing, wherein:

Figure 1 illustrates in part the upper portion of a pair of trousers comprising the zipper fly closure showing the underside of the overlapping fly member embodying the features of my invention; the overlapped fly member is shown in part; (some of the zipper elements of the respective zipper tapes are not shown); the rows of stitches are shown in dotted lines; 7

Figure 2 illustrates the overlapping flymember before the zipper tape is attached thereto;

Figure 3 illustrates a sectional view on line 33 of Figure 2, on enlarged scale;

Figure 4 shows the fly member structure shown in Figure 2, with the zipper tape attached to the fly member.

The ordinary zipper fly closure of trousers comprises an overlapping fly member and a complementary overlapped fly member and through the medium of a slide device the respective members unit or separate at will. Zipper elements are mounted on the respective edges of the zipper tapes. One of the zipper tapes is attached to the overlapping zipper fly member by a longitudinal line of stitching; the zipper tape adds some thickness to the longitudinal portion of the overlapping zipper fly member by being covered by the zipper tape; the area of the fly member adjacent the front of the zipper is comparatively thinner in texture than the longitudinal portion of the fly member where'the line of stitching extends for the attachment of the zipper tape thereto;

the tendency is that front portion of the overlapping fly member is easily bendable outwardly with respect to the garment and the consequence follows that the shiny zipper elements are exposed when the complementary zipper elements are united when the garment is worn.

To overcome the exposure of the zipper elements would require some resistance to prevent the outward bending of the overlapping fly member. It has been proposed to insert stiffening material between the overlapping fly member and the adjacent garment material; such stifiening material soon loses its rigidity through washing or the stiflening substance dissipates through drycleaning chemicals; to provide a lining material that comprises resisting quality for the purpose stated would call for a lining that comprises a comparatively thick material with the consequence that the fore part of the fly closure would become objectionably conspicuous and depart from the neatness that a trouser fly closure requires.

Referring in detail to the drawings, numeral 10 represents the upper portion of a pair of trousers having a zipper fly closure; 11 represents the overlapping fly member; 12 represents the overlapped member of the fly structure; 13 represents a row of transversely extending stitches in grouped relation; a plurality of such rows in suitably spaced relation extending longitudinally along the length of the overlapping fly member; 14 represents a zipper tape having zipper elements 15 mounted on the outer edge thereof; 16 represents a line of stitching attaching the zipper tape 14 to the overlapping fly member 11; 17 represents the underply of fly member 11; '18 represents the fore part of thetrousers upper portion adjacent the fly member 11; 19 represents the. underply of said fore part; 20 and 21 represent the folded edge of the fly member 11 and the fore part 18, respectively; stitches 22 securing both edges together. It will be seen that the transversely extending stitches pass through the outer material of the overlapping fly member and also the underply thereof, thus similar rows of stitches as 13A.

are present at the underside of the fly member; thus in a way there are four thicknesses thereat to produce rigidity at the region of the overlapping fly member to resist the tendency of the overlapping fly member and the material of the adjacent fore part to flex outwardly and expose the zipper elements. The plurality of the rows of stitches 13 may comprise units of double rows in adjacent relation and suitable spacings between the respective units.

Sewing machines are available that will produce the grouped stitches of the transverse rows, or attachments may be employed with the conventional sewing machine to produce such stitches; in either, the work may be produced substantially by automatic action at a low cost. It will be seen that the individual stitches of the respective rows extend longitudinally with respect to the longitude of the overlapping fly member.

While in the foregoing specification and the accompanying drawing there has been disclosed a preferred embodiment of the present invention, it will be understood that changes may be made from the precise'disclosure without departing from the spirit and scope thereof. It is therefore desired that what is claimed be given broad interpretation and be limited only by the prior art pertaining thereto.

I claim:

A garment fly closure comprising an overlapping fly member; a zipper tape having a row of zipper elements secured at the outer edge thereof; said tapebeing attached to said fly member by a line of stitching extending longitudinally along the inner side of said row or" zipper elements; said fly member and the adjacent fore part of the garment each having a folded outer edge; said fly member comprising a ply at the underside thereof in contiguous relation with an underply extending inwardly from said folded outer edge of said fore part of the garment; the folded outer edge of said fly member being secured to said fore part adjacent the folded outer edge thereof; a plurality of transversely extending rows comprising grouped stitches across the width of saidfly member; said rows being suitably spaced in relation to one another; the individual stitches of the respective rows being disposed substantially longitudinally with respect to the length of said fly member; said transversely extending rows of the stitches providing rigidity to said fly member substantially over the area extending from the line of attachment of the zipper tape to said overlapping fly member to a point suitably adjacent to the folded outer edge of said overlapping fly member; the arrangement being such that exposure of the zipper elements with respect to the overlapping fly member is substantially obviated.
