Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Patent Application No. 60/724,176, filed on October 6, 2005 . The content of the provisional application is hereby incorporated by reference.

BACKGROUND

The present invention relates to undergarments, and more particularly to men's and women's seamless undergarments.
Undergarments, more commonly known as underwear and having multiple configurations such as boxers, briefs, bikini cut, etc., are commonly worn under the clothing to support the wearer's body under his or her clothes, as well as to provide a more comfortable garment between the wearer's skin and his or her clothes. Recently, strides have been taken to increase the comfort of undergarments for both men and women, including using softer fabrics and removing the tags from the undergarments to prevent irritation.
Another feature of undergarments that has been changed to increase both the comfort of the wearer as well as the appearance of the garment is to reduce the number of seams on the garment. The seams can also cause irritation to the user, as well as detracting from the appearance of the garment by disrupting the contour of the garment with respect to the body of the wearer. A challenge presented in producing seamless undergarments is that the seamless undergarment is essentially formed from a tube, and yet must conform to the contoured body of the wearer to ensure a comfortable fit. It is thus desirable to provide an undergarment with increased comfort and support for the user, as well as improved aesthetic appearance of the garment.

DETAILED DESCRIPTION

Fig. 1 illustrates an undergarment 14 embodying aspects of the present invention. The undergarment 14 comprises various zones of stitching that will be described in detail below. The undergarment 14 includes a first front panel 18 and a second front panel 22. The first and second front panels 18, 22 are composed of the same stitch pattern. In the illustrated embodiment, a 4x1 mock rib stitch is used in the first and second front panels 18, 22, though it is understood that other stitches could be used. The rib stitch results in vertical ribs 24 evenly spaced about the first and second panels 18, 22.
The 4x1 mock rib stitch results in an evenly ribbed outer surface of the panels 18, 22, and an inner surface (i.e., the surface that rests against the skin of the person wearing the undergarment 14) that has the look and feel of terry cloth. Thus, the inner surface is soft and can absorb any moisture on the skin, and the outer surface of the panels 18, 22 is aesthetically pleasing and provides a smooth, contoured fit. In addition, the terry cloth effect of the rib stitch allows air to circulate between the body of the wearer and the fabric by keeping the fabric from making 100% contact with the body of the wearer, increasing the comfort of the wearer.
Positioned between the first and second front panels 18, 22 is a pouch area 26. The pouch area 26 includes sections of varying stitch types. Along the perimeter of the pouch area 26 is an area of reduced stretch stitching 30. The reduced stretch stitching 30 provides a transition between the front panels 18, 22 and the pouch area 26 such that no ripples or bunching occurs at the transition point between the panels 18, 22 and the pouch area 26.
A pouch 34 is constructed of a jersey stitch to provide a roomy cavity. Releasing the stitching of the pouch such as by using the jersey stitch creates the cavity in the pouch 34 for increased comfort of the wearer. The 4x1 mock rib stitch of the front panels 18, 22 assists in displacing the jersey stitch fabric to create the cavity. The reduced stretch stitching 30 also provides support to the pouch 34. Above the pouch 34 is an area of alternating 1x1 fine mesh stitching 38. In the illustrated embodiment, ornamental stitches 42 are also provided in the pouch area 26 to improve the aesthetic appearance of the undergarment 14.
A waistband 46 is formed at the top of the front panels 18, 22. With reference to Fig. 2, the waistband 46 encircles the top of the undergarment 14 and includes a first portion 50 and a second gripping portion 54. The first and second portions 50, 54 are similar in that they both are constructed of a 1x1 mock rib stitch utilizing cotton, nylon, and spandex strands within the stitches. The first portion 50, which constitutes the lower portion of the waistband 46, is stitched using threads containing 66% cotton, 26% nylon, and 8% spandex. The second portion 54, which constitutes the top of the waistband 46 and is smaller in width than the first portion 50, is stitched using threads containing 53% cotton, 37% nylon, and 10% spandex.
The increased percentages of nylon and spandex in the second portion 54 increases the modulus of elasticity of the second portion 54 with respect to the first portion 50. The higher modulus of elasticity creates a cupping effect on the edge of the band, allowing the waistband 46 to pull in more towards the body, and increases the gripping strength of the second portion 54 with respect to the wearer's body. The configuration of the waistband 46 thus anchors the undergarment 14 into position on the wearer's body without pinching or digging into the skin of the wearer. The increased grip reduces the likelihood that the waistband 46 can roll down upon itself when the undergarment 14 is worn by the wearer. It is understood that the specific construction of the threads used in the waistband 46 can vary from the embodiment discussed above and still fall within the scope of the invention, so long as at least one of the first and second portions 50, 54 results in an increased grip strength with respect to the other of the first and second portions 50, 54 to provide a cupping effect of the waistband 46 against the body of the wearer.
A leg band 58 is formed at the bottom of each of the front panels 18, 22. As best illustrated in Fig. 3, each leg band 58 includes first and second portions 62, 66 that are constructed and function in the same way as the first and second portions 50, 54 of the waistband 46 discussed above. The second portion 66 includes the increased percentages of nylon and spandex, as discussed above with respect to the second portion 54, thereby increasing its modulus of elasticity, and thus its grip strength. The increased grip strength results in a leg band 58 that more comfortably grips the leg of the wearer, with less bunching and rolling of the undergarment 14 on the wearer's leg. The design of the leg band 58 also provides more comfort to the user by reducing the likelihood of the undergarment 14 riding up the leg of the wearer. Ornamental stitches 70 are located above the leg band 58 to create a visibly pleasing transition between the stitching of the front panels 18, 22 and the stitching of the leg bands 58.
Fig. 4 illustrates a rear view of the undergarment 14. As illustrated in Fig. 4, the undergarment 14 also includes first and second rear panels 74, 78. The same type of stitch, i.e., the 4x1 mock rib stitch that is used in the front panels 18, 22, is used for the rear panels 74, 78, resulting in vertical ribs 82. However, the length of the stitches forming the ribs 82 is longer and looser than the stitch used to form the ribs 24 such that the ribs 82 of the rear panels 74, 78 are slightly contoured, whereas the ribs 24 are substantially flat. The slight excess of material created by the longer, looser stitches in the vertical direction results in the contour of the ribs 82. The longer, looser stitch, and thus the contour, accommodates the contoured rear end of the wearer to maintain a smooth and supportive fit.
Between the rear panels 74, 78 is a central portion 86. The central portion 86 includes an area 90 constructed of a 1x1 fine mesh stitch on either side of a center strip 94. The 1x1 fine mesh stitch provides a smooth transition between the rear panels 74, 78 and the center strip 94 such that no rippling or bunching occurs. The center strip 94 is constructed of a modified stitch pattern that exhibits reduced stretching in the vertical direction compared to the rear panels 74, 78.
In general, it is desired to maximize the stretching properties of the fabric in some zones of the undergarment 14 so that the undergarment 14 can comfortably move with the wearer as the wearer's body moves. Varying the length of the stitching in different zones of the undergarment varies the stretching properties in those zones to achieve a better fit and more comfort for the three dimensional shape of the wearer's body. However, the area of the body against which the center strip 94 rests is an area that exhibits little or no stretching in the vertical direction, even during bending and other movement by the wearer, due to the anatomy of the wearer. Thus, the center strip 94 is constructed to have reduced vertical stretching.
A support panel 98, also constructed of the 4x1 mock rib stitching, is coupled to the front and rear panels 18, 22, 74, 78. The support panel 98 is constructed separately from the remainder of the undergarment 14, as will be discussed in more detail below, and the stitching is configured to allow for sculpting of the undergarment 14 to the rear end of the wearer without causing pinching or digging.
Fig. 5 illustrates the interface between the shorter, flat 4x1 mock rib stitch forming the ribs 24, and the longer, contoured 4x1 mock rib stitch forming the ribs 82. The interface includes a zig-zag portion 102 that interleaves portions of the front panel 18 with portions of the rear panel 78. The interface is three dimensional due to the difference in stitch length between the front and rear panels 18, 78. The interleaving of the front and rear panels 18, 78 allows for a seamless, comfortable fit, and results in a front portion F that is shorter in height, and thus sits lower on the wearer's body, than a rear portion R of the undergarment, as viewed from the side. The difference in height between the front F and the rear R allows the undergarment 14 to conform comfortably to the wearer's body in all positions of movement, rest, and stretching.
The interleaving of the front and rear panels 18, 78 also provides a smooth, less abrupt transition between the shorter, tighter stitch of the front panel 18 and the longer, looser stitch of the rear panel 78 such that no rippling or bunching occurs. Such rippling or bunching not only could detract from the overall appearance of the undergarment 14, but could irritate the wearer or cause the undergarment 14 to bunch or move in a way uncomfortable to the wearer, as well as decrease the support of the wearer's body. It is understood that while a substantially Z-shaped zig-zag pattern is illustrated and described above, other interface configurations are possible (e.g. sinusoidal, trapezoidal, stepped, etc.) that would provide for a smooth transition between the front and rear panels 18, 78.
The undergarment 14 with the features described above is constructed to have a virtually seamless design. In known undergarment configurations, the undergarment is constructed from multiple panels of cloth that must be stitched together, creating seams at various points on the undergarment. These seams are not only distracting visually, but also can cause discomfort to the user. In other known undergarment configurations, abrupt transitions between various stitch types result in seams or virtual seams due to rippling and bunching.
The undergarment 14 described above is constructed using a machine known as a SANTONI Seamless knitting machine, a piece of equipment well known to one of ordinary skill in the art. Using the SANTONI machine, the undergarment 14 is largely created in a single process, out of one panel of material. The exception to this is the support panel 98, which is created separately and is sewn to the remainder of the undergarment 14 resulting in seams 106 (shown in Figs. 1 and 4). The support panel 98 is sewn in separately to increase the support to the inner thighs of the wearer of the undergarment 14.
The remaining zones of the undergarment 14 are constructed from beginning to end by the SANTONI machine, which can be programmed to vary the stitch type and stitch length in different zones of the undergarment. As discussed above, some of the zones of the undergarment 14 are constructed to provide smooth transitions between stitch zones having different constructions to provide an undergarment that is both aesthetically and functionally pleasing.
Figs. 6 and 7 illustrate another embodiment of a women's undergarment of the present invention. Similar reference numbers are used to identify similar elements as previously described. Undergarment 110 has a first front panel 18 and a second front panel 22. The first and second front panels 18, 22 are composed of the same stitch pattern (e.g., a stitch pattern forming a matte appearance). An alternate stitch pattern between the front panels 18, 22 creates a central front 114. Ornamental stitches 42 are also provided to improve the aesthetic appearance of the undergarment 110. A waistband 46 is formed at the top of the front panels 18, 22. The waistband 46 encircles the top of the undergarment 110 and includes a first portion 50 and a second gripping portion 54. A leg band 158 is formed at the bottom of each of the front panels 18, 22. The undergarment 110 also includes first and second rear panels 74, 78. Between the rear panels is a central portion 86 having a reduced vertical stretch compared to the rear panels 74, 78. The first and second rear panels are composed of the same stitch pattern (e.g., a stitch pattern forming a shear appearance). Zig-zag portions 102 interleave portions of the front panels 18, 22 with portions of the rear panels 74, 78 to blend the different stitch patterns.
Figs. 8 and 9 illustrate an additional embodiment of a women's undergarment of the present invention. Similar reference numbers are used to identify similar elements as previously described. Undergarment 118 has a first front panel 18 and a second front panel 22. The first and second front panels 18, 22 are composed of the same stitch pattern (e.g., a stitch pattern forming a matte appearance). An alternate stitch pattern between the front panels 18, 22 creates a central front 114. Ornamental stitches 42 are also provided to improve the aesthetic appearance of the undergarment 118. A waistband 46 is formed at the top of the front panels 18, 22. The waistband 46 encircles the top of the undergarment 118 and includes a first portion 50 and a second gripping portion 54. A leg band 158 is formed at the bottom of each of the front panels 18, 22. The undergarment 118 also includes first and second rear panels 74, 78. Between the rear panels is a central portion 86 having a reduced vertical stretch compared to the rear panels 74, 78. The first and second rear panels are composed of the same stitch pattern (e.g., a stitch pattern forming a shear appearance). Zig-zag portions 102 interleave portions of the front panels 18, 22 with portions of the rear panels 74, 78 to blend the different stitch patterns.
Figs. 10 and 11 illustrate another embodiment of an undergarment of the present invention. Similar reference numbers are used to identify similar elements as previously described. Undergarment 122 has a first front panel 18 and a second front panel 22. The first and second front panels 18, 22 are composed of the same stitch pattern (e.g., a stitch pattern forming a matte appearance). An alternate stitch pattern between the front panels 18, 22 creates a central front 114. Ornamental stitches 42 are also provided to improve the aesthetic appearance of the undergarment 122. A waistband 46 is formed at the top of the front panels 18, 22. The waistband 46 encircles the top of the undergarment 122 and includes a first portion 50 and a second gripping portion 54. A leg band 58 is formed at the bottom of each of the front panels 18, 22. The leg band 58 has includes a first and second portions 62, 66 that are constructed and function in the same way as the first and second portions 50, 54 of the waistband 46 of Figs. 1-5. The undergarment 122 also includes first and second rear panels 74, 78. Between the rear panels is a central portion 86 having a reduced vertical stretch compared to the rear panels 74, 78. The first and second rear panels are composed of the same stitch pattern (e.g., a stitch pattern forming a shear appearance). Zig-zag portions 102 interleave portions of the front panels 18, 22 with portions of the rear panel 74, 78 to blend the different stitch patterns. A support panel 98 is coupled to the front and rear panels 18, 22, 74, 78 resulting in seams 106.
All of the components discussed in detail above work together to achieve a common goal: a better fitting, more comfortable undergarment that supports and moves comfortably with the body of the wearer sculpted from an essentially tube shaped garment. The sculpted silhouette results from the stitching patterns utilized to create the undergarment. The features discussed above also result in an undergarment that is smooth and visually attractive, comfortably following the contour of the wearer's body. The features of the undergarment discussed above are applicable to all styles of undergarments, including but not limited to briefs, boxers, low rise, a high-waist brief, a french cut brief, a triangle bikini, a hip brief, and the like. It is also understood that the specific thread compositions and the specific stitch types used above can be varied and still fall within the scope of the invention and should not be interpreted as limiting the invention to any one thread composition or combination of stitch types.
Various features and advantages of the invention are set forth in the following claims.
