(Cl. 2-224) This invention pertains to mens undergarments and in particular to the type commonly called briefs. It is a continuation-in-part of the application for United States Letters Patent Serial No. 740,674, now abandoned, entitled Undergarment, filed June 9, 1958. 4

With the advent of stretchable synthetic fabrics the development of new basic concepts was made possible in the construction of garments. For. example, the stretchable synthetic fabrics have led to the development of the stretch hose. These hose have the characteristics of being able to accommodate a large range of sizes due to the stretchable properties of the material from which 3,319,446 Patented Feb. 6, 1962 tersecting plane shown in FIGURE 4, intersecting a cylin drical form representing the thigh of the wearer.

FIGURE 5 is a side view in elevation similar to that shown in FIGURES 3 and 4,

Although the material used in the construction of the garment embodying the invention will be described in terms of stretchable fabric, it is contemplated that other types of fabrics may be used. By stretchable fabric it is meant one that has the characteristic of being substantially stretchable in at least one or more directions. One fabric that has been found particularly suitable for the subject garment has stretch characteristics of 300 percent in the cross drection and 100 percent in the longitudinal direction. Such fabric is composed of a yarn con, sisting at least partially of a polyarnide material and sold under the trademark Helanca by the Dupont Comp-any.

3 However, other synthetic-fabric fibers, such as polyester they are constructed. By eliminating the necessity of fabrics be used in the construction of mens undergarments of the type commonly called briefs. By briefs it is meant drawers which are essentially form-fitting and which have the salient feature of providing support for the male parts. However, it has been found that when briefs are constructed of the stretchable fabrics along conventional and heretofore known designs, they have the tendency to become bunched or gathered in the crotch of the wearer and consequently become uncomfortable. For these reasons among others a brief has been invented which has a foremost feature and object of providing a brief which is essentially form-fitting and in which the tendency to become bunched or otherwise gathered in the crotch of the wearer is substantially eliminated.

Another important feature and object of this invention resides in the provision of a brief which has the salient feature of providing support for the wearer.

Another object of the invention is to provide a brief which is stretchable throughout a major portion of its construction so that an individual garment can accommodate a range of sizes rather than a single size.

Another object of the invention is to provide a brief which is especially suited to be constructed of a stretchable synthetic fabric and is designed to be essentially form-fitting.

These and other objects of the invention will be apparent upon reading of the specification with reference to the following drawings:

As was stated previously, there are two major considerations in the design of this garment that must be met if the garment is to provide comfort for the wearer. Firstly, the garment must not bunch in the crotch of the wearer or otherwise become displaced from the portions of the body upon which it ordinarily rests. It has been found that attempts to design a garment alongthe lines used for those constructed of ordinary fabrics in which there is little or no stretch cannot meet this requirement for reasons that will be seen later on. In particular due to the natural resiliency of these stretchable fabrics, the garment will tend as the result of the movements of the wearer to slide over the buttocks so as to become bunched in the crotch when conventional designs are use. Accordingly it was necessary to invent a design which rninimizes any such tendency if stretch fabrics are to be utilized in the manufacture of briefs.

A second consideration which is of vital importance is to provide suflicient support for the parts of the wearer. Due to the resiliency and stretch characteristics ofthe fabric, ordinary designs commonly used heretofore do not provide the needed support. For this reasonit was again necessary to invent a brief having a construction which provides sufiicient support for the wearer as well as eliminates any tendency to become bunched or otherwise distorted from its usual position Referring now to FIGURE 1, there is shown an undergarment generally denoted by the numeral 10, which hereinafter will be called a brief. The brief is provided with a band 12 which is adapted to circumscribe and engage the thighs of the wearer as best shown in FIGURES 3, 4, and 5. As shown in these drawings, particularly in FIGURE 5, it can be seen that the rear portion of the rband 12 rides considerably higher on the wearer than the A front body portion or section 14 is secured to the band by any suitable stitching as shown in the drawings. Preferably the lower edges of the strip 13 are folded inwardly on themselves and sewn together along with the front body portion so as to form a seam of five thicknesses of material.

A rear body portion or section 16 i sewn to the band 12 in the same manner as the front body portion 14.

Intermediate the front body portion 14 and the rear body portion 16 is a relatively narrow band of material which serves as the crotch portion or section 18, as shown in the drawings. The crotch portion 18 in one preferred form is merely an integral extension of the front and back portions 14 and 16.

A reinforcement member 20 is sewn to and partially overlies the front body and crotch portions 14 and 18, as shown in FIGURES l and 2. The reinforcement member in its upper extremity lies in the front body portion 14 and in its lower extremity lies in the crotch portion 18. This reinforcement member provides additional support to the wearer over that resulting from a single thickness of the material. In its preferred form the reinforcement sec.- tion 20 is constructed of the same. stretchable fabric used in the construction of the brief.

It should be pointed out that in this particular brief the fabric is orientated so that it has approximately 100 percent stretch in the vertical direction and 300 percent stretch in the horizontal direction. It is possible, however, that other stretch relationships may be used in the construction of the garment.

Extending around the outer edges of the front and rear body portions and the crotch portion are the legbands 22. The legbands 22 may be constructed in a conventional fashion of a strip of material 23 folded on itself to form an enclosure (not shown). An elastic member (not shown) extends through the enclosure and is substantially hidden from view. The marginal portions of the front and fear body portions 14 and 16 and the crotch portion 18 extend into the enclosure and are sewn to the legbands 22. As a result of this construction, the legbands 22 are elastic so as to permit insertion of the legs of the wearer without any undue discomfort.

As can be seen from the drawings, the upper ends of the legbands 22 are sewn directly to the band 12. Thus, any forces tending to distort the fabric will be brought directly to bear upon the legbands 22 and in turn the band 12. The band 12 and the legbands 22 naturally provide greater resistance to stretching than does a single thickness of material. Accordingly this arrangement makes it possible to provide the desired support to the wearer without any discomfort resulting from being too tight. The resistance to stretch, of course, may be varied by the use of different types of elastic so as to provide the desired support.

As shown in the drawing, the garment is constructed so that the lower portions 22a of each of the legbands 22 follow the base of the buttocks at their juncture with the thighs, so that the rear body portion 16 substantially covers the same. The lower portions 22a further tightly conform to the contour of the rear and rear-side portion of the respective thigh. It will be noticed that the line defin ing the base of each of the buttocks along which the lower portions 22a lie reaches its lowest point at the rear of the thigh and gradually slopes upwardly as it extends to the outward side. Such a line will normally lie in a single sloping plane 26 shown by the dotted lines in FIGURE 3. It can be further seen that the garment is constructed so that the upper portions 22b of each legband 22 also lie in the sloping plane 26'. Thus, in the direction of the sloping plane 26, the upper portions 22b are straightline projections of the respective lower portions 22a.

The intersection of the sloping plane 26 of the thigh of the wearer can be more clearly seen by referring to the idealized construction shown in FIGURE 3a. In this illustration the plane 26 is shown intersecting a cylindrical member 27 with the cylinder being positioned so as to correspond with a side view of the thigh with the right and left edges of the cylinder 27 representing the rear and front portions of the thigh respectively. From the drawing it can be seen that the plane intersects the rear portion of the thigh and slopes upwardly until it intersects the front portion of the thigh. The slope of the plane is determined by that necessary to intersect an imaginary line corresponding to the juncture between the buttocks and the thigh and which would extend along the right hand side of the cylinder 27.

For purposes of reference, the practice heretofore has been to extend the upper portions in a generally vertical direction or at least at a much steeper slope than the natural plane shown in FIGURE 3. While this type of garment is suitable for ordinary fabrics which have little or no stretch, it does permit the undesirable bunchingi when stretchable fabrics are used.

One possible explanation for the desirable results ob-- tained from the garment embodying the invention will now be described. When the wearer bends at the waist, the rear body portion will be stretched, thus tending to force the legbands, particularly the lower portions 22a, to be displaced upwardlyand slide over the buttocks. The bend-- ing, howeven will also stretch the upper portions 22bwhich in turn will stretch the lower portions 22a. Since the upper portions 22b lie in the same plane as the lower portions 22a, the stresses imparted by the former will be in a substantially longitudinal direction to the latter, sothat there is no tendency to displace the latter upwardly along the surface of the buttocks. As a matter of fact, such stretching along the natural plane described herein-- before will cause the lower portions 22a to embrace the body even more tightly and actually provide resistance to displacement. This additional resistance appears to overcome the forces induced by the stretching of the rear body' portion.

It can be seen that the forward portions 221 may ex tend at a lower or even slightly greater slope than the aforementioned plane and still obtain the beneficial results of this invention. This principle of the invention may be broadly characterized as extending the portion 22b sufliciently forward of the portion 224: so that stretching of the legband will not lead to upward displacement of the latter.

Referring now to FIGURES 4 and 5, there is best shown the positioning of the legbands 22 associated with the front body portion 14. It will be noted that the junctures of the groin area with the thighs lie respectively in the planes 28, one of which is indicated by the dotted lines shown in FIGURE 4. The garment is constructed so that substantially all of the portions 220 of the legbands 22 associated with the front body portion 14 lie along the aforementioned juncture between the groin area and the thighs. The portions 22d extend rearwardly of the portions 220 at a slope not greater than the plane 28. As the result of this arrangement, any stretching of the portions 22c and 2211 will not tend to cause inward displacement which would permit bunching.

The intersection of the plane 28 with the thigh of the wearer can best be seen by referring to FIGURE 4a. In this illustration the cylinder 29 is positioned so as to correspond to a front view of the thigh. The plane 28 slopes downwardly in a direction extending from the front to the rear of the cylinder 29 so that the highest point of the intersection is at the outside portion of the thigh and the lowest point is at the inside portion of the thigh adjacent the crotch area. The slope of the plane is determined by that necessary to intersect any imaginary line corresponding to the juncture between the thigh and the groin area and which would extend along the right hand side of the cylinder 29.

The unique construction of each legband with respect to the front body portion may be broadly described as extending the portions 22d sufliciently rearwardly of portions 22c so that stretching of the legband will not lead to inward displacement of the latter.

As shown in FIGURE 5, the upper portions 22b and 22d of each legband will normally cross slightly below the band 12 when the garment is designed along the concepts previously described. This crossing, however, is dependent upon the physiological characteristics of the wearer for which the garment is designed.

While the legbands 22 are shown as being cut with the ends sewn to the band 12, other constructions are possible. For instance, the bands 22 may be uncut and connected to the band 12 in any manner suitable to follow the concepts described previously regarding their position on the wearer.

In its preferred form and by actual practice it has been found that the subject garment can be designed for the greatest percentage of wearers in any particular size group by limiting the range for any garment to three sizes, such as 28-32, 30-34, 3236, etc. This range is primarily limited by the rear body portion in order to eliminate bunching.

It will be further noted that the garment may be constructed of separate body portions or of an integral piece of material, except for the reinforcement member 20 and bands 12 and 22 respectively. As a result of the latter arrangement a single blank can be cut out of the fabric and then sewn to the band 12 and the legbands 22.

It can now be seen this type of design provides an economical garment which is extremely effective as a brief. Furthermore, it can be seen that by constructing this garment according to the principles of the invention, it is possible to provide an individual garment which is suitable for a range of sizes and which retains all of the comfort of the ordinary sized garments.

Although a preferred embodiment of the invention has been described, it is to be understood that this is merely by way of example and in no manner to be construed as a limitation. It is contemplated that certain modifications may be made within the scope of the claim without departing from the spirit of the invention.
