The invention relates to knitted garments and more particularly to mens trunks such as are used for swimming or for under garments.
One object of the invention is to provide a novel 5 pair of knitted trunks having a reinforcing section knit into the front of the trunks as an integral part thereof and constituting a supporter. l Another object of the invention is to provide a novel pair of knitted trunks embodying a reinforced waist band and supporter loop extending through the crotch of the trunks and having the lower selvage edges of the trunk legs inclined at the proper angle relative to the waist band.
The invention also resides in novel features of construction which impart shape and rein' forcement to the trunks and enable the same to t the wearers body nicely.
Further objects and advantages of the invention will become apparent as the following description proceeds, taken in connection with the accompanying drawings in which Figure 1 shows a pair of trunks embodying the invention in place on a wearer.
Fig. 2 is an enlarged perspective view of the pair of trunks of Fig. 1.
Figs. 3 and 4 are-respectively top and front elevations of the trunks.
Figs 5 and 6 are respectively vertical sectional views along the lines 5-5 and 6-6 of Fig. 4.
Fig. 7 is an enlargedfragmentary view Of a portion of the trunk fabric.
Fig. 8 is a fragmentary view of the crotch portion of a modified form of the trunks.
The invention has been shown herein as applied to a pair of mens bathing trunks, but it will be apparent that the invention is,'in certain of its aspects, also applicable to other types of knitted garments. The particular pair of trunks chosen for illustration of the invention embodies similarly shaped front and rear pieces I and II of knit fabric, each having a straight upper selvage edge I2, side edges generally perpendicular to the upper edge, and lower selvage edge portions I3 and I4 converging downwardly and inwardly to a central edge portion I paralleling the upper edge I2 in the form of the invention shown in Fig. 4. Each front and rear section is knit as integral pieces of fabric and may, as shown in the present instance, be knit together integrally at one side edge. The other side edges are sewed together to form a compact seam I6 along the other hip. To complete the trunks, the central edge portions I5 are sewed together at a similar crotch seam I1. The inclination of (Cl. (i6-176) or waist edge is such as to impart proper shape to the legs of the trunks.
y The front and rear pieces Ill and II of the trunks are of generally similar shape although the rear piece is preferably somewhat wider. In fashioning the front piece III, for example,`the knitting is started with a course of stitches or loops at one side edge of` the garment and the -knitting carried on in continuous wales across the entire front portion of the garment. Preferably, though not necessarily, full or half cardigan stitches are employed depending on the elastic characteristics desired. Worsted or any other desired type of yarn may be employed.
The invention contemplates reinforcement of selected portions of the front and rear pieces I0 and I I so as to form a straight elastic waist band I8 along the upper edges I2 and a band I9 prei'- erably extending from the waist band I8 downwardly through the crotch and then upwardly along the center of the rear piece to the rear of the waist band. To assist in retaining the desired shape of the legs of the trunks, it may be desirable to provide narrow reinforcing bands 20 paralleling the supporter band and extending along each side edge of the front and rear pieces. For purposes of design or shaping, additional narrow reinforcing strips 2I may be knit in adjacent but spaced from the supporter band. The parts 22 and 23 of the front and rear pieces between the reinforcing bands extending downwardly from the Waist band and terminating at the edge portions I3 and I4 are not reinforced and therefore are looser so as to stretch re'adilyand conform to the contour of the wearers' body.
In the form shown in Fig. 4, the wales of the reinforced sections extend horizontally and parallel the selvage edge I2 constituting the upper edge of the waist band. Inxthe other sections 22 and 23, the wales are inclined slightly as indicated by the shading in Fig-4 so'that the selvage edges I3 and I4 will define the lower end of the trunk legs. Cutting and seaming of the fabric to shape the legs is thus avoided.
Such inclination of the wales is effected by an operation known in knitting as knee-racking. One form of flat knitting machine by which this may be accomplished forms the subject matter Jof my copending application Serial No. 238,837 filed Nov. 4, 1938. As therein disclosed, the bank of needles by which the sections 22 and 23 are formed are racked in the course of knitting relative to the remaining needles knitting the waist band. The effect of such racking is to form the racking so as to form a straightselvaged edge I3 which diverges from the waist band. By racking in the reverse direction, 4 the. reverse inclination of the edge I4 is obtained. The reinforcing bands I9, 20 and 2I are formedby knitting in l of the trunk legs, the effect of the racking operation is to produce a substantial amount of fullness indicated at 25 (Fig. 2) in the unreinforced portions. This fills out and conforms readily to the wearers body thereby contributing to the nicety of fit of the garment.
Reinforcement of the fabric to form the waist, supporter, and side bands I8, I9, and-20 may be effected in various ways as, for example, by using different Weights of yarn in different sections as by using elastic yarn in knitting the reinforced section and worsted yarn in the other sections.v
It is preferred, however, to obtain somewhat greater reinforcement by using one yarn 26 (Fig. 8) throughout the front and rear pieces and adding elastic yarn 21 selectively in the sections which are to be reinforced. Such yarn includes a rubber strand encased in fine cotton,
silk, worsted, or other threads. A characteristic."
full cardigan stitch coresponding to the area en` closed by dotted lines in Fig. 4 is shown on a magnified scale in Fig. 7. This also illustrates the effect of the racking operation above described.
Since the main supporting action isy produced by the band I9 in the front piece I0, the band in the rear piece may, in order to" reduce yarn costs and lessen the weight of the trunks, .be reinforced to a lesser degree. This may be effected by adding reinforcing yarn21 in alternate or even in every third or fourth round while the band I9 in the rear piece is being knitted By reinforcement in this manner, the bands I8 to 2l are heavier and more closely knitted. They impart the proper elasticity to the garment and form an effective vsupporter in the front piece. The support is thus knit in as an integral part of the front piece. In addition, the reinforced portions cooperate to retain the desired shape of the garmentf'as a whole while permitting of the desired looseness and fullness in the other portions.
Instead of forming the supporter band I9 with straight horizontal wales and a flat bottom edge I5, the knee-racking action may be continued .j'clear to the vertical center line of the front and rear pieces and the reinforcing yarn added in any selected portion. In such a case, the Wales on opposite sides of the front pieces would converge to points 28 of intersection at the center of the piece as shown in Fig. 8. Thus, the inclined edges I3 and I4 would extend clear to the point 29 of intersection. The elastic yarn 2'I would, of course, be knit into the central part to form the band or supporter as indicated by the shading. In order to avoid the necessity of cutting off the pointed end in forming the crotch seam, the racking would, during knitting of the rear piece, be carried on in such a manner as to form a V-notch at the centerpoi its lower edge. This notch would be complemental to and interfit with the pointed end on the front section so that the two selvage edges may be sewed together forming a V-shaped seam 30.
With the construction above described, it is possible to very quickly and economically knit the front and rear portions as integral unitary pieces,
9,220,279A wales at an incline controlled by the amount of each or both in one continuous operation. No
subsequent cutting of the pieces or building in of a supporter are necessary. 'I'he only subsequent operations which need be performed are lthe sewing up of the sides of the garment and the lower ends of the supporter loop reinforcing sections to form the crotch. Despite this simplificationof manufacturing procedure, a garment is provided which -keepslts shape well and which affords good support to the wearer. Further-,- more, the waist band fl-ts snugly about the wearers waistso that no belt is required and any tendency for the sides of the trunks to creep or roll up along the wearers legs is reduced to a minimum.
The incorporation of the garment reinforcements into the fabric of the garment itself results not only in a simplification of construction,
but also gives the trunks a pleasing appearance.v
The differentiation in appearance between the reinforced and unreinforced sections of the trunks has been disproportionately emphasized in the drawings in order to make clear the location of the reinforced sections. In the actual garment, the presence of the reinforcing strands is almost imperceptible, the principal difference of appear- 'ance in the reinforcing sections being due only to the fact that the stitches have an appearance of beingesomewhat more tightly knitted than in the remainder of the garment.
Although a particular embodiment and application of the invention have been shown and described in some detail, there is no intention to thereby limit the invention to such embodiment or application, but on the other hand, the appended claims are intended to cover all modifications in structure falling within Ithe spirit and scope of the invention.
