Title: Ergonomically engineered underwear

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates generally to an undergarment, and more particularly to a man&#39;s undergarment having the combined quality and characteristics of a brief and an athletic supporter but designed to provide comfort and support rather than a &#34;compacting&#34; effect of a normal athletic supporter and which is of scant dimensions and fits snugly about a man&#39;s body with leg openings of such size as to provide additional comfort to the wearer not found in briefs. 
     2. Discussion of the Prior Art 
     An athletic supporter has been and is currently widely used. This type of supporter consists of elastic straps holding a knitted pouch. The pouch has no body and consequently does not maintain a predetermined shape. Moreover, the athletic supporter does not have any covering cloth panels except for the pouch, and obviously does not take the place of a brief, shorts, trunks, or the like. The athletic supporter is usually worn by those engaged in sports for protective purposes, and is not usually worn by man in his everyday activities or pursuits. If one would wear such athletic supporter during normal activities, an additional undergarment such as shorts would also be worn to provide coverage for the buttocks and adjoining body portions. 
     In addition, it is also understood that the conventional briefs or undergarments of this general type, do not provide the support of the kind attributed to an athletic supporter. These undergarments are made of cloth that sags, pinches, rubs or rides up, and have an inside fly that reduces or precludes any supportive characteristics that might otherwise exist. 
     One such prior art garment is shown in U.S. Pat. No. 3,499,442 to Steinmetz which discloses a man&#39;s supporter brief undergarment that includes an elastic U-shaped pouch strap attached to an elastic waistband, and an elastic panel attached to and located inside the U-shaped strap to provide a shaped, supporting pouch at the front of the garment. A pair of elastic leg straps are attached to the U-shaped strap substantially at the strap bight, and are attached to opposite sides of the U-shaped strap to provide leg openings. A cloth covering is attached to and extends between the waistband, pouch strap and leg straps. Although Steinmetz purports to provide additional room for comfort, the pouch is vertical and would not provide much additional room. In addition, the leg openings would also not be large enough to prevent binding while seated. 
     U.S. Pat. No. 2,534,024 to Hochbaum, although not directed to a man&#39;s undergarment, discloses women&#39;s underwear of the type which is of scant dimensions and fits snugly about a person&#39;s body and is formed along its sides with leg openings of such size that margins of the leg openings fit closely about upper portions of the legs. 
     U.S. Pat. No. 4,972,525 to Hwang discloses underpants with smooth side panels free of protruding edges and elastic bands to provide comfort during sleeping on either side to minimize waistband discomfort and render the sides of the underpants inconspicuous when worn under a pair of trousers or skirt. Although Hwang provides large leg openings, it does not provide a pouch for male wear. 
     All of the above patents are directed to the comfort of the wearer and are attempts to solve the problems associated with wearing undergarments. However, each of the prior art improvements are restricted by their use of conventional shapes and materials. Merely combining the features of an athletic supporter with those of a pair of briefs is insufficient to correct the problems with the prior art undergarments. 
     SUMMARY OF THE INVENTION 
     The invention is a personal suspension system which is ergonomically designed for proper fit and proper support. The system comprises four major parts, the insert, the front, the back and the waist band. Each of the various parts are designed so that when sewn together, they provide a perfect fit for each size. 
     The garment construction eliminates the prior provision of an inside fly in a brief which consists of an opening in the pouch. Instead, the garment provides an &#34;outside fly&#34; that enables ready access to the pouch interior without adversely affecting the supportive quality of the brief, the &#34;outside fly&#34; constituting that portion of an elastic strip in the front panel adjacent to the insert and defining the leg opening. Consequently, the undergarment can be worn by men at all times as during work, leisure or periods of increased physical activity, and the garment will provide the modest covering, holding, moisture absorbing and comfort of a brief and athletic supporter. The garment is lightweight, flexible and snug fitting. 
     Wearing the underwear of the instant invention permits greater motion in a sitting position without the discomfort of binding. Once the garment is put on and the man&#39;s genitals are held by the insert, they are protected away from the body and are less likely to be injured. It has been found that there is no need to adjust the position of the genitals once they have been placed in the insert. Unlike the image of athletes continuously making adjustments on the television screen, adjustments are not required with the instant invention. Any movement of the body is accommodated by the stretch of the elastic and the stretch material of the invention. Many of the improvements of the instant invention would not have been possible when the cited prior art was developed because of the availability of the new stretch fabrics, threads and available sewing techniques.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to FIGS. 1-3, the undergarment includes an insert 11, front panel 12, back panel 13, and a continuous, endless, waist band 14, adapted to fit around the waist of the wearer. Front panel 12, made of stretch-textured material is attached to the waist band 14. The front panel 12 is cut from a folded blank of material as shown in FIG. 5 and is contoured to precisely fit the anatomy as shown at insert cut 15 and contoured edges 16, 17, and 18. Along the contoured edges 17 of front panel 12, elastic is applied to form the front part of the leg openings 20. Elastic is also applied to the contoured edges 21, 22 of back 13. The elastic edges 17, 21 and 22 of the leg openings 20 are elastic which are stretchable longitudinally and secured at their ends so that they have a tendency to contract and draw the side edge portions of the garment into close fitting engagement with the legs of the person wearing the garment. These elastic bindings also cause the side edges of the crotch portion to be held snugly in place but since the bindings may be stretched longitudinally, it is possible to greatly enlarge the leg openings and draw the crotch portion and the front section towards one side where it will be out of the way when responding to calls of nature (the outside fly). 
     Bottom contoured edge 19 of back panel 13 is sewn together with edge 18 of front panel 12 to form crotch seam 19. Top contoured edge 23 of back panel 13 is sewed to waist band 14 as shown in FIG. 3. 
     The insert 11 is assembled from four units as shown in FIG. 6. After assembly, the contoured edges 24, and 25 of the insert 11 are sewn into the cutout formed at 15 in front panel 12. Four sections of cutouts are used to form insert 11 to provide the large receiving pouch of the garment, and to provide sufficient material to absorb any mistakes or surplus body liquids. The large pouch created by assembly of the insert provides the room necessary for comfortable underwear. In addition, the fact that the insert protrudes away from the body prevents the pressures normally applied by prior art undergarments which generally are constructed with vertical
