Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Patent Application No. 60/816,098 filed Jun. 23, 2006.

BACKGROUND OF THE INVENTION

This invention relates to an article of clothing, specifically cycling shorts. This invention also relates to an associated method of manufacture.
Shorts for the serious bicycle rider are typically made of a knitted synthetic resin material with substantial stretchability in multiple direction enable a tight fit to the wearer's anatomy. For purposes of cushioning and enhanced moisture absorption, a pad of nonwoven absorbent material is provided inside the shorts in the crotch region thereof. The crotch pad places certain constraints on the adaptability of the shorts to different positions and motions of the user.

SUMMARY OF THE INVENTION

The present invention aims to provide a new kind of cycling shorts wherein the crotch pad is better integrated into the shorts structure. The present invention concomitantly aims to provide an associated method for manufacturing a pair of cycling shorts.
Cycling shorts in accordance with the present invention comprise a plurality of panels of stretchable fabric material and a crotch pad of absorbent material. The fabric material has a first thickness, while the pad material has a second thickness substantially greater than the first thickness. The pad has a plurality of edges joined to edges of selected ones of the panels disposed adjacent to and contiguous with the pad.
Typically, the fabric panels are made of the same type of material and have a common thickness and a common weight. The pad may have a thickness that varies across the pad but the pad has a minimum thickness that is larger than the common or uniform thickness of the fabric panels.
The fabric panels are typically cut from a knitted polymeric material such as nylon.
Pursuant to another feature of the present invention, the pad is connected to the panels only at edges thereof. This arrangement contrasts with the construction of conventional cycling shorts, where the edges of the crotch pad are sewn along central areas of the pre-existing shorts.
In a particular embodiment of the present invention, the fabric panels include a crotch panel identical in size and shape to the pad and extending coextensively therewith. In this embodiment the crotch panel and the crotch pad overlap one another completely, the edges of the crotch panel and the edges of the pad being laterally adjacent, in a direction perpendicular to the plane of the pad, and connected to one another. The edges of the pad abut the edges of the other panels and are adjacent thereto in a direction parallel or tangential to the pad.
Preferably, the pad is joined to the selected or adjacent panels by stitches or sewn thread.
In another embodiment of the cycling shorts, the pad serves as a panel of the cycling shorts and may thus be visible from the outside, instead of covered or masked by a fabric panel.
A method for making cycling shorts comprises, in accordance with the present invention, cutting a plurality of panels from stretchable fabric material (generally knitted), providing a crotch pad of absorbent material, joining the panels to each other and to the crotch pad only at edges of the panels and the crotch pad to thereby form a tubular body portion and two tubular leg portions.
The joining of the panels to each another and to the crotch pad may include sewing or stitching the panels to each another and to the crotch pad.
Where one of the panels is geometrically congruent with the crotch pad, the method further comprises aligning the one panel with the crotch pad so that the one panel and the crotch pad are coextensive and completely overlap one another. The joining of the panels to each another and to the crotch pad includes sewing or stitching edges of the one panel to corresponding laterally adjacent edges of the crotch pad.
In the manufacture of conventional cycling shorts, a complete shorts structure is first made and subsequently the crotch pad is overlaid and stitched to the pre-existing shorts. In contrast, the present invention contemplates that a complete shorts structure comes into being only with the crotch pad already integrated therein. Without the crotch pad there would be a hole in the crotch area of the shorts. This is the case even where there is a crotch panel coextensive with the pad. The crotch panel is joined to the other panels at the same time that the pad is sewn in place, not before.
The crotch pad in cycling shorts in accordance with the present invention is a padded gusset that is preferably sewn to adjacent fabric panels via a seam link stitch, a modified 2-needle over-lock stitch.
Cycling shorts constructed in accordance with the present invention incorporate a dynamic pad system, providing enhanced flexibility, better fit and improved moisture wicking.

DETAILED DESCRIPTION

Cycling shorts 10 comprises a plurality of panels or sections 12 of stretchable fabric material and a crotch pad 14 of absorbent material. Panels or sections 12 are made of the same type of material and have a common thickness and a common weight. Fabric panels or sections 12 are cut from a knitted polymeric material such as nylon.
The fabric material of panels 12 has a uniform or common thickness substantially thinner than the thickness of pad 14 at any point. Pad 14 may have more than one thickness, for instance, where the pad is terraced along an inner surface. In other words, pad 14 may have a thickness that varies across the pad but the pad has a minimum thickness that is larger than the common or uniform thickness of the fabric panels 12.
Pad 14 has a plurality of edges 16 joined to contiguous edges 18 of adjacent fabric panels including two central front panels 20 and 22, two flanking inner leg panels 24 and 26 and a lower rear panel 28.
Pad 14 is connected to panels or fabric sections 12 only at edges 18 thereof. Thus, pad 14 does not overlap any fabric panel or section 12 (e.g., panels 20, 22, 24, 26, 28), with the exception of an optional covering sheet or crotch panel 30.
Crotch panel 30, if provided, is identical in size and shape (congruent) to crotch pad 14 and is coextensive therewith. Crotch panel 30, if provided, overlaps completely with crotch pad 14, with the edges 32 of the crotch panel and the edges 16 of the pad being laterally adjacent, in a direction perpendicular to the plane of the pad 14, and connected to one another by appropriate stitching. The edges 16 of pad 14 abut the edges 18 of the other panels 12 and are adjacent thereto in a direction parallel or tangential to the pad.
Pad 14 is joined to front panels 20 and 22, inner leg panels 24 and 26 and lower rear panel 28 by stitches or sewn thread. The stitching may be a modified 2-needle over-lock stitch that is a variation of a standard 3-thread operation, but uses only I needle thread and a bottom looper thread. In this modified stitch, the upper looper is replaced with a special “hook” looper (looks a bit like a thick, bent seam ripper) and receives no thread; the needle tension is loosened almost completely and the looper thread tension stays as per normal setting. The width of the overlock finger on the plate combined with the needle tension is what determines the finished width of the seamlink. A smaller finger will always produce a smaller finished seam, while a standard finger will produce the desired seam width, both are adjustable to a degree by the needle thread tension. The tighter the tension is, the narrower the finished width will be and the bulkier the underside of the seam will be. When the needle tension is almost nill, the result is a flattest, widest finish. The density of the stitch depends on the stitch length and needs to be experimented with on each fabric to determine an appropriate density.
This modified 2-needle over-lock stitch requires a 2 step process, namely, (1) the sewing operation as described above, and (2) pulling the stitch perpendicular to the seam direction manually and before any congruent seams are constructed.
Where crotch panel 30 is omitted, pad 14 serves as a panel of the cycling shorts 10 and may thus be visible from the outside, instead of covered or masked by fabric panel 30.
In a method for making cycling shorts 10, one cuts fabric panels or sections 12 from stretchable knitted material and joins the panels to each other and to crotch pad 14 only at edges 18 of the panels and the edges 16 of crotch pad 14 to thereby form a tubular body portion 34 and two tubular leg portions 36 and 38.
The joining of fabric panels 12 to each another and to crotch pad 14 is accomplished by sewing or stitching the panels to each another and to the crotch pad. Where one of the panels (30) is geometrically congruent with crotch pad 14, the method further comprises aligning crotch panel 30 with crotch pad 14 so that the crotch panel and the crotch pad are coextensive and completely overlap one another. The joining of the panels 12 to each another and to crotch pad 14 includes sewing or stitching edges 32 of crotch panel 30 to corresponding laterally adjacent edges 16 of crotch pad 14.
Although the invention has been described in terms of particular embodiments and applications, one of ordinary skill in the art, in light of this teaching, can generate additional embodiments and modifications without departing from the spirit of or exceeding the scope of the claimed invention. For instance, where there is a fabric crotch panel that is coextensive with and covers the crotch pad, the crotch panel may be connected first to the other fabric panels, prior to the joining of the pad. This method requires double stitching or dual and overlapping seams along the edges of the pad and the crotch panel. In any case, the pad is connected to the fabric panels only at the edges of the panels. Accordingly, it is to be understood that the drawings and descriptions herein are proffered by way of example to facilitate comprehension of the invention and should not be construed to limit the scope thereof.
