Bielefeld, Germany The present invention relates to garments, particularly day-shirts, provided with exchangeable collars and cuffs.

Germany, assignor to referred to by the same reference It is generally known that the exchangeable collars of day-shirts are fastened to the annular fastening rim at the neck-portion of the shirt either by means of studs, or by means of buttons fastened at one part and buttonholes provided at the other part.

off during the washing and that the studs frequently get lost. It has, therefore, already been tried to substitute for these button-closing-rneans, flap like closing means.

It is further known that the sewed-on buttons usually become damaged or torn However, the way in which the flap-like closing means have so far been devised has been unsatisfactory regarding the reliable-attachment of the collar to the fastening rim and for that reasonwere the cause of continuous trouble. For the detachable fastening of the culfs the difiiculties were even more pronounced, for which reason the use of exchangeable cuffs has in many cases already been abandoned.

Because of the quick soiling of collars and cuffs, shirts provided with exchangeable collars and cuffs are preferred by many people, although shirts provided with attached collars appear to be more comfortable in use.

Hence, the object of the invention is to overcome the deficiencies of known constructions and to provide a dayshirt with detachable collar and cuffs which is as comfortable in use as a shirt provided with attached collar and cuffs.

The present invention solves the problem by providing a garment, particularly a day-shirt having at least one detachable part, an annular fastening and at each connecting place with said detachable part as one element, said detachable part as another element, one of said elements to be detachable connected to one another being at least double walled and provided at a plurality of connecting points with pockets, the other element being provided at said connecting points with opposite fastening tabs having parallel side edges, consisting of textile material stifienedby chemical means, and fixed by several transverse rows of stitches near one end for holding the tabs closely to said element in a position for mutual cooperative self-holding action with said corresponding pockets, being made by sewing together portions of said double-walled parts to form recesses of like shape and dimensions as said corresponding tabs. The tabs consist preferably of an outer textile covering and one or a plurality of stiffening strips, wrapped up in that outer covering, whereby the stiffening strips may consist of textile strips suited for stiffening by chemical means and heat treatment, and of strips suited for the absorption of the chemical stiffening means.

Additional features and advantages of the present invention will be understood from a consideration of the following detailed description taken in connection with the accompanying drawings, forming a part of this specification and in which two embodiments of the invention have been shown by way of example. However, I wish to say that the invention is not confined to any strict 2,885,682 Patented May 12, 195974 ice conformity with the showing of the drawings, but may be changed or modified, so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claim.

In the accompanying drawings, in which like parts are numerals,

Fig. 1 is a fractional view of a day-shirt provided with detachable tum-down collar and cuffs;

' Fig. 2 is a cross-section on line II-II of Fig. l; ,v Fig. 3 is a fractional view of a day-shirt similar to that of Fig. 1, but having the flap-like fastening means arranged at the collar in a different way;

Fig. 4 shows in outstretched position a cuif detachably fastened to the lower end of a sleeve;

Fig. 5 is a cross-section on line V-V of Fig. 4;

Fig. 6 is a cross-section on line VI-VI of Fig. 4;

Fig. 7 shows the essential parts of a plug strip prior to being stitched together;

Fig. 8 shows the plug strip of Fig. 7 stitched together and provided with a plurality of longitudinally extending rows of stitches;

Fig. 9 shows the flap-like fastening member ready for being stitched onto the collar and cuffs.

Referring now to the drawings in detail, the reference numeral 1 designates the shirt, while 2 is the annular neck portion of the shirt to which the turn-down collar 3 is attached. Detachably fastened to the lower end of the sleeve 4 .is the cuif 5. The collar3 and-the 'cuiF-S are provided on the outside of their

inner fastening portions

13, 14 with fastening flaps 6 adapted for engagement in pockets 7 formed at the inner side of the annular neck portion 2 and of the fastening portion 8 of the sleeve 4. The fastening flaps 6 and appertaining pockets 7 are arranged near the ends of the collar 3 as well as the cuffs 5 and near the vertical center 'line of the collar and cuifs. The flaps or tabs 6 have a width approximately the same as the pockets and a length substantially equal to the depth of the pockets to provide a close fit. The appertaining pockets 7 are formed at the neck portion 2 and sleeve portions -8 through circum-sewing of portions of the double-walled fastening portions 2 and 8 through the provision in the circum-sewed portions of slots provided with reinforced edges in button-hole-like fashion. All of the fastening flaps 6 and appertaining pockets 7 extend in the collar 3 of the embodiment of Fig. l transversely of the longitudinal direction of the collar, while in the cuffs 5 of the same embodiment the flaps and pockets extend at the ends of the culfs 5 transversely of the longitudinal direction and between the two ends in longitudinal direction of the cuifs 5. If between the ends of the cuffs 5 a plurality of flaps 6 are arranged they should preferably extend in opposite directions. It is further feasible to arrange the flaps 6 between the two ends of the cuffs 5 in such a way that they extend in alternately longitudinal and transverse direction, whereby then merely the longitudinally extending flaps 6 should extend in opposite directions with respect to each other.

Fig. 2 shows a cross-section of the collar 3 and annular neck portion 2 on line 11-11 of Fig. 1.

Fig. 3 shows an embodiment in which the flaps 6 positioned near the ends of the collar extend in transverse direction, while the flaps 6 at the back of the collar 3 extend both from the vertical center line of the collar 3 in longitudinal direction, and in opposite directions with respect to each other, toward the ends of the collar 3.

Fig. 4 shows the end of the sleeve 4, with the cuff 5 detachably fastened to it, in outstretched position, while Figs. 5 and 6 show cross-sections of the cuff 5 and sleeve portion 8 on lines V--V and VI-VI of Fig. 4. Here, the flaps 6 positioned near the middle of the cuff 5 extend in opposite directions toward the ends of the cuff 5 whereby unintended loosening of the flaps 6 from their appertaining pockets at the sleeve portion 8 is rendered very diflicult.

.The fastening flaps :6 are formed from a 1 linen strip -9, having twice the widthsof the .flaps, .an acetate .silk.strip 10 of .slightlysmaller width, and a cotton .band '11 thaving 41116 width of the ,flaps. These parts -are placedon top of each other (as shown in Fig. 7), then longitudinally folded up, then stitched together attheredges, and then provided witha plurality of parallel longitudinallyextendingrrows of .stitches.12,.as .shownin/Figm 8. The bandlike strip thus obtained is then impregnated with acetone and methylic alcoholin a moist-press, whereby the artificial threads of the acetate silk become dissolved, and then dried-and stiifenedin a hot;pr.ess. From a ,strip produced in this way the individual flaps v6 are separated through ,punching,.cutting or the like, with around edge at one of their ends, vwhereupon the opposite end is fastened by two transverse rows of stitches to the collar .Zor cufi-5.
