Technical Abstract

A men's undergarment consisting of a torso-encircling waistband attached to a single panel of fabric with the wider portion affixed at the back of the waistband, then narrowing between the legs before re-attaching at the front of the waistband to form the brief. A line of stitching spans the narrow panel from thigh to thigh. The front portion of the garment includes a sleeve formation with a soft, piped opening through which the penis extends. A wide, exterior panel drapes loosely from the waistband covering the front opening and shielding the penis.

Detailed Description

Complete technical specification and implementation details from the patent document.

This inventive subject matter is an undergarment specifically directed for a male wearer that includes the following features: single-body construction incorporating a unique thrust dynamic that adjusts the scrotum forward for maximum comfort; extension of the penis through an opening maintains the advancement of the scrotum while also allowing for the cool comfort of separation; protection of the exposed penis with a draped cover panel for both safety and hygiene; and elimination of fabric gathering within the posterior cleft serves to benefit the wearer specifically with improved scrotum protection, reduced binding, cool comfort and increased freedom of movement.

Briefs generally contain a separate crotch panel that cradles the scrotum, and most include various folded mechanisms through which to retrieve the penis, while others provide pouches and separations, both with or without openings. While the inclusion of a separate crotch panel allows additional room for the scrotum, combining this available space with gravity and circumstance can result in painful pinching of the testicles, particularly when sitting.

Conventional brief designs also confine the penis and scrotum within the same space, which can cause perspiration, chaffing, raised testicular temperatures and overall discomfort to the wearer. Utilizing a single-body construction creates a forward momentum which is further enhanced by a simple line of stitching (), that, combined with extension of the penis, serves to draw the scrotum forward, thereby cooling and improving overall comfort for the wearer.

Boxers provide a sense of unrestricted freedom, while briefs provide support. This innovation incorporates both aspects by supporting the scrotum, while allowing the penis to move unrestricted beneath the cover panel that simply tucks into the outwear, as one would tuck in a shirt-front.

The placement of elastic that forms the leg openings () creates a dynamic tension that acts to deter the uncomfortable collection of fabric within the posterior cleft of the buttocks, which has been a common complaint, and also creates an effective barrier between the thighs and the scrotum to reduce heat and friction.

The functionality of the loin cloth is centuries old, and this invention now incorporates the safety and support of a brief for truly unprecedented comfort.

Prior art demonstrates separation of the penis and scrotum from the thighs, and separation of both the penis and scrotum through an opening with affixed covers that range from fully attached to waistband attachments. This invention differentiates through utilization of a single-body construction to overcomes multiple challenges by employing simple dynamic tension for true comfort and ease of movement.

There remains a need for a male undergarment that reduces painful pinching and uncomfortable gathering, while enhancing ventilation and comfort for the wearer.

The inventive subject matter is an undergarment designed specifically for the male gender that encircles the lower torso, and specifically employs the dynamic tension of single-body construction coupled with elasticized leg openings independently affix to the waistband, to serve three distinct purposes: 1) draws the scrotum forward to prevent uncomfortable pinching of the testicles; 2) increases cooling and comfort of testicles by separating thighs, scrotum and penis; and 3) prevents the gathering of fabric within cleft of the buttocks.

This invention incorporates a simple elasticized brief covering the buttocks, wherein the placement and attachment of said elastic serves to hold the fabric taunt, thereby preventing the unwanted gathering of fabric in the posterior cleft. Single-body construction plus a soft barrier of stitching draws the scrotum forward, which is further enhanced by extension of the penis through lined opening at the front of the garment.

The primary embodiment of the inventive subject matter includes a protective panel extending from the waistband to cover the front portion of the garment thereby shielding the penis for purposes of safety and hygiene. Subsequent embodiments describe alternate designs of said front panel, several of which designate said panel as a separate attachment. Therefore, one embodiment involves the brief with the lined opening as a singular garment, maintaining that the overall construction of the brief is in itself is key to the invention.
