The present invention relates to wearing apparel and particularly` to trousers or slacks or the like.

An object of the present invention is to provide a trousers construction, and method of making the same, which will be pleasing in appearance and comfortable when worn.

Another object of the ,presenJ invention is to provide a trousers construction which will be at and non-bulky in the area of the separable fastening and which .will lie ilat against the waist of the wearer.

Another object of the present invention is to provide a method of constructing the waistband portion of a pair of trousers or the like, which will be an inexpensive, easy and rapid method of assembly and which will produce a far superior garment than heretofore available.

An additional object of, the present invention is to provide a trousers constructionwhich includes a slide-fastener as a closure member, and which provides neat and effective means for attaching the closure member to the fly-portion of the trousers.

Another object is to provide a ily construction for trousers wherein the upper corner is rounded and the waistband edge and ily-edge blend together around a radius.

Further objects of the present invention, will be readily discernible by reference to the ap,- pended specification, claims and drawings.

Where a slide-fastener is used as the closure member of a pair of trousers or the like, it is desirable to conceal the uppermost end of the slidefastener tape in orderto provide the garment with a neat appearance. This conventionally requires that the waistband extend beyond and over the vppermost edge of the ily-portion (which is generally co-extcnsive with the uppermost edge of the slide-fastener tape). r'his conventional type of construction is not entirely satisfactory because it results in excessive bulk at the juncture zone of the waistband, the fly-portion and the leg-portion and, in addition, makes it impossible to finish off the waistband with the rounded corner Which is considered important in good tailoring.

In attempts to elirfinate this extra bukiness and to secure the rounded edge construction, various Special constructions have been suggested which have the disadvantage of requiring extra pieces and additional stitching operations such as appreciably add to the cost of the garment,

rl'he present invention contemplates a new and improved construction whereby this excessive bulkiness is eliminated and the rounded` corner obtained without the need for extra pieces or stitching operations and at a cost no greater than is the case with conventional constructions.

Generally speaking, the present invention comprehends a new and improved trousers construction as well as a novel method of making the same whereby the seam fastening the outer edge of the ily-portion to the corresponding edge of the leg-portion is formed in such a manner as to minimize theV excessive bulkiness at the juncture point of the leg and fly-portions with the waistband, andwhereby asecond seam is thereafter appliedso as to extend upward as a straightlinecontinuation of the irst-mentioned seam and across and around the inturned end of the waistband portion sopas to permit trimming oli of the straight edges at the corner of the waistband portion, thereby providing a nal construction whfreinthe vertical seam at the free edge of the waistband portion extends as a direct straight line continuation from the seam connecting the ily-portion to the leg-portion, and, at the same time, providing a smoothly-curved upper free edge for the waistband.

For the purpose of illustrating the invention, there are shown in the accompanying drawings, forms thereof which are at present preferred, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and that the invention is not limited to the precise arrangements a-nd organizations of the instrumenta'ities as herein shown and described.

Fig. le represents a fragmentary front elevational view of the inside of the completed trousers.

Fig. l represents a View generally like Fig. 4, but showing a modification thereof.

Referring tc Figures 1 and 2, there is shown a trousers construction including a leftleg panel 2?, permanently attached by stitches 2 i to a left waistband portion 4i, a slide-fastener 22, composed of tape-and-element portions 22-a and 22-b, buttons 2', and 2d., and a right leg-portion 25, permanently attached by stitches 25-2 to a right waistband portion 23. A blacky portion, shown generally as at 21, is secured to the extreme edge of the left leg-panel, in a manner to more fully disclosed hereinafter, so as to overlie and cooperate with a white-ily portion 21-b attached to a right leg panel 25 and a right waistband panel 23.

As is shown in Figure l, the method employed in securing the slide fastener tapes 22-a. and Z2-b to the trousers requires seam-lines 29 and 3B between the ny-portions and waistband portions whereby the ends of the slide-fastener tapes may be securely and neatly concealed underneath the waistband.

The first step in constructing the waistband of the present invention is the assembly of the fly 21, and is shown in Figure 3. A generally elongated liner portion 3i, having substantially the same shape as the fly-portion 32, is securely fastened to said y-portion and to the slidefastener tape 22-c by rows of stitching 33--a and 33-b with the edge 35 of the liner 3i spaced slightly away from the outer edge 36 of the y portion 32. Both the fly portion 32 and the liner 3i may be somewhat J-shaped so as to conform generally t0 the body of the wearer,

4 following a pattern well known to those skilled in the art.

Referring now to Figure 4, this View shows that the y 21 is attached to the leg panel 2i), by a row of stitching 31, spaced somewhat away from the edges 35 and 36, and for the most part parallel to said edges. However, it is noted that near the top of the assembled members the row of stitching 31 gradually approaches the edge 35, so as to meet the edge 36 at a point somewhat below the extreme upper edge 38 of the assembled body-portion and ily-portion. The point at which the seam 31 contacts the edge 36 should be approximately one-half inch (1,/2 below the edge 38, but this dimension may vary somewhat. That is to say, the seam 31 may contact the edge 36 somewhat below or somewhat above the point indicated, but nevertheless terminate in such a manner that approximately 1/2 of the ily-portion and leg-portion may be separated easily (as at 39 and itil).

As shown in Figure 15, the leg-panel 28 and y-assembly 21, may, instead, be attached by a seam 31-a which, at all points, is generally equidistant from the edge 38, and which terminates somewhat short of the upper edge 38. This assembly provides an upper portion of the leg panel 2li and the fly-assembly 21 which is not secured by the seam 31-a.

In each of the embodiments of Figures 4 and 15, therefore, the seam 31 (or 31-a) does not bind together the upper portions 39 and fit of the members 29 and 21. The function of this gap will be more fully disclosed hereinbelow.

After the leg portion 20 and the fly-portion 2 have been secured by the seam 31, the assembled members are then secured to the waistband portion M, as shown particularly in Figure 6. In this step the leg portion 20 is pivoted about the ily-portion 21 (with the seam 31 serving as a hinge), and the outer surface of the waistband portion 4l is placed adjacent the outer surfaces of portions 23 and 21, with the inverted lower edge 42 of the waistband 4| adjacent the upper edge 38 of the fly and the leg portions. In this position the edge 40 of the fly-portion is in abutting end-to-end relationship with the edge 39 of the leg portion (as shown at 34) in Figure 6. Thereafter, the waistband portion lll is secured to the fly-portion 21 and leg portion 23 by a horizontal seam 43 which is parallel to the edges 42 and 38 and somewhat below these edges. Thus the seam d3 passes at or above the point on edge 36 at which seam 31 terminates.

Referring now to Figures 4-l-a, 6-a, and 'l-a, there is illustrated the assembly of trousers according to prior practice. Figure i--a is a View similar to Figure 4, but it represents the priorart construction, wherein stitching 31-b is continued to the top edge 33 of the assembled portions 21 and 2U. In such construction no gap, as at 39 and 40, is possible, and the edges i-a and llt-a could not be made to lie in an abutting relation, as is possible with my construction, shown in Figure 6.

Figure G-a represents the prior-art construction corresponding to my assembly shown in Figure 6. As is evident, the end portions, a and l0-a, cannot abut, and must be folded against the panel 20, causing a 4-ply thickness at that point. Thereafter stitching :i3-a must pass through all Ll-plies (plus the liner 3i). This multi-ply construction obviously creates a bulky garment. Such undesirable features are eliminated from the garment using my construction.

S The cross-sectional views-of Figs', '7" andi-'I-a further-illustratehowmy garment is-animprove'- mentl over prior-arti.

After-seam 43- Ihas-secured themembers- 21, 20 andE 4l together, the Vwaistband:portion 1Hv is pivoted about the seam` 43 (as shown particularly in ligure)` and the ends All-a, 21`a and 2lia are foldedv back4 against `their respective portions. The ends-4 l-a, 21---aA andZOL-a arethen pressed flat tominimize any bulkinessl created bythese folds.

The next step consi-sts Uin'A pivoting the fly-portion 21, and theend-portion lll-b of the waistband portion- 4|- about-'the -edge 36- (and a continuation 4 l-c thereof in theA waistband portion-l. The folding oper-ation, shown'as partlyperformed in- Figure 9', is shown in the-completed vstepin Figure'l.

Referring now to-Figure 1'0, a seam 44v (which is parallel tothe-edge 36`and the fold-line 4|-c) secures the iiy-portion -and leg portion ator-below thelpointat which seam 31 begins to taper towards edge 3and` extends upward toward the waistband 4l. This seam 44 is, therefore, an` extension of` the straight' part of seam 31, upward across the'seam 43-into the folded-over section of the waistbandconsist-ing of portions 4l and 1 -b."

In the-waistband portion the seam 44'is caused to-followa radius, as at 45', so that it can thereafter continue parallelA to the upper edge 46- of the waistband portion 4I; ln this manner the y-portion 21, and the end-portion 4|b of the waistband 4|, arermly secured in a contacting relationship totheleg-panel 2B and the waistband 4 I.

After the seam 44Y-has`been applied tothe assembled members, the-excess material between the edge 36-and seam 31, and between edge 4I--c and seamv 44, is removed so that only a small prothe seams 31 and 44. The assembled panels, with the trimmed edges, are Shownin Figure 11.

After the excess material has-been removed, a waistband liner 41 may beattached to the upper edgeof the waistband member as shown inFigure 13. Thereafter, the liner 41 is folded against they insideof the waistband panel 4|, and the members2-1and4I-b are folded over along the seams 31- andl 44 so as to expose the outersurr' face ofthe fly-portion 32 and the slide-fastener 22. This operation-is shown-as completed in Figure 14. A seam 59 Amay be employed to hold the members in this nal position.

Thus, I have-provideda trousers opening which includes a minimum number of material-plies in the'region ofthe upper end of the ily-portion, particularlyV at the point where the slide-fastener tape 22 a passes inside the waistband portion and where the waistband and leg members are secured to the ily-portion.

Moreover, because seam 441s a straight-line continuation ofv seam 31, the nal fold is made easily'without any-twists or bulges in the material, and the-edge 5lI is straight and neat-appearing. In addition, the-presence of seam 44 and the radius 45, and the use of the trimming oper-ation-aforementioned, provide an upper corner 48 of the trousers with a rounded edge which is highly. desirable sinceedge 46 is not always aocurately. in-linewith the opposite edge 49, when the y-portion of. the trousers is closed by the slide-fastener22zand`the-buttons 23.and 24. This roundedredge tendsr to decrease the obviously undesirableA appearance ofanyimis-alignment of the y edgesISiandi-IS and:` enhances the appearanceof the" trousers when in the closedposition.

Thus, Iy have provided` a: trousers construction which eliminates-anybulkyor` unsightly material attherupper edgeof they---portions and waistbandv portions without materially increasing. the costlofthe garment,

Thepresent invention-maybe embodied in otherspecific forms without departing from-the spirit or essential attributesr thereof, andi itis therefore Jdesired' that the present embodiments be considered infallrespects as illustrative` and not restrictive,A referencebeing had to therappended claims rather than-to the-foregoing descriptionto indicatethe scope of the invention.
