DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings, and in particular, FIG. 1, there is provided a brassiere generally represented by reference numeral 10. Brassiere 10 is shown as a conventional brassiere and includes a pair of breast-receiving cups 15, a torso-encircling band 30 and a pair of back panels 20. Each shoulder strap 40 is connected to one of the pair of breast receiving cups 15 and to one of a pair of adjustable back strap assemblies 35. Each shoulder strap 40, as shown more clearly in FIGS. 2 and 3 has a shaped area with a non-slip portion 55.
Referring to FIGS. 2 through 4, a first embodiment of the strap 40 of the present invention is shown. Strap 40 has an upper support layer 45 having a surface 46 and lower layer 50, respectively. Strap 40 has a front end 48 that is connected proximate the breast cup of brassiere 10 and a back end 47 that is connected to a strap assembly 35 of brassiere 10. Strap assembly 35 has a strap adjustment element to change the length of strap. Alternatively, adjustment feature could be located at the front of brassiere 10. Upper support layer 45 has a very smooth profile to ensure a smooth appearance beneath clothing. Upper support layer 45 is made from a smooth fabric such as, for example, polyester, although other materials could also be used. Lower layer 50 is made from two materials, a non-slip foam portion 55 and a smooth portion 57. Smooth portion 57 can be made from the same material as upper support layer 45.
Non-slip foam portion 55 contacts the skin of the wearer during wear of brassiere 10. Non-slip foam portion 55 is made from a material that has a nap and provides a degree of friction between itself and the skin of the wearer. Non-slip foam portion 55 is preferably made form a soft foam material such as a material called PORON™, that is owned by Rogers Corporation. PORON™ is an open celled microcellular polyurethane that is a urethane polymer. Non-slip foam portion 55 has a sueded or buffed texture that ensures strap 40 will not slide or move from the shoulder of the wearer during wear. Other materials similar to PORON™ that offer a similar textured surface that would resist sliding on the shoulder of the wearer could also be used.
Layers 45 and 50 of strap 40 have a curvilinear shape, for example, an elongated ovoid shape that is widest at the non-slip foam portion 55. Non-slip foam portion 55 is advantageously positioned at the top of the shoulder to resist slipping or shifting on the shoulder during wear and active movement. Thus, the broad non-slip foam portion 55 is provided where it is particularly necessary to offer the greatest amount foam material to effect the non-slip function. Layers 45 and 50 each contain stitching 65 and 70, respectively, to connect layers 45 and 50.
Referring to FIG. 4, the profile of brassiere strap 40 and upper support layer 45 and lower layer 50 are shown. Strap 40 has a smooth profile even though a foam material is used in its assembly. In many brassieres, a foam strap feature adds unwanted bulk to the strap and a visible contour beneath clothing. By having the non-slip foam portion 55 as a skin contacting surface, that disadvantage is eliminated.
FIG. 5
a shows the cup fabric 90 of brassiere strap 40 having an inner layer of netting material layer 82. Similarly, inner side of non-slip layer 55 is also covered by a netting material layer 80 such as for example, stabilized microfiber or stabilized tricot. Netting material layers 80 and 82 are laminated to the non-skin contacting layer of non-slip portion 55 and inner cup fabric layer 90 prior to strap assembly. Netting material 80 allows non-slip layer 55 to be sewn to create seams 65 and 70 without peeling or fragmenting during the assembly process. Each layer 55 and 90, respectively, is folded under itself to prevent fraying of a free edge and to provide greater strap integrity. Further, netting material layers 80 and 82 have minimal thickness so that the overall profile of strap 40 remains slim and not visible beneath clothing. Alternatively, as shown in FIG. 5b, cup fabric 90 can be sewn to non-slip portion 55 and netting layer 80 without netting layer 82.
Referring to FIG. 6, a second embodiment of the brassiere strap of the present invention is shown and generally referenced using reference numeral 51. Strap 51 is similar to strap of FIG. 2 and FIG. 3; however, strap 51 has a straight configuration. Strap 51 has a first surface 52 and a second surface 56. Surface 52, a skin contacting surface, has a non-slip portion 54 and a smooth portion 53. Non-slip portion 54 is also made from PORON™ to ensure that strap 51 does not slip on the shoulder of the wearer during wear. Other materials similar to PORON™ that offer a similar textured surface that would resist sliding on the shoulder of the wearer could also be used. Second surface 56 is a support surface of brassiere cup to which non-slip portion 54 is connected, preferably, using stitches 58. Second surface 56 is has a smooth profile to ensure a smooth appearance beneath clothing. Second surface 56 is made from a smooth fabric such as, for example, polyester, although other materials could also be used. Smooth portion 53 is also made from a smooth fabric, such as for example polyester.
FIG. 7
a shows a cross-sectional view of the strap of FIG. 6. Second surface 56 of brassiere strap 51 has an inner netting material layer 63 connected thereto. Similarly, inner side of non-slip layer 54 also has a netting material layer 66 such as for example, stabilized microfiber or stabilized tricot, connected thereto. Netting material layers 63 and 66 are preferably laminated to and inside surface of second surface 52 and to inner side of non-slip layer 54, respectively, prior to strap assembly. Netting layer 66 allows non-slip layer 54 to be sewn without peeling or fragmenting during the assembly process. Further, netting layers 63 and 66 have minimal thicknesses so that the overall profile of strap 51 remains slim and not visible beneath clothing. In the present embodiment, non-slip layer 54, its laminated to netting layer 66, and smooth portion 53 to form a straight configuration. Non-slip layer 54 and netting layer 66 have free ends 68 that are cut and are laminated together. By having free ends 68, strap 51 maintains a desirable thin profile beneath clothing. Were the edges folded over and sewn between the strap surfaces, strap 51 may potentially be visible beneath clothing. Further, the manufacturing of a straight strap is more efficient because the cutting and sewing processes are shorter and simpler. Alternatively, as shown in FIG. 7b, second surface 56 is sewn non-slip portion 54 and netting layer 66 without netting layer 63.
A third embodiment of the present invention is shown in FIG. 8. Strap 100 has non-slip portion 110 and a comfort feature 105. Comfort feature 105 is preferably inserted in strap 100 during the assembly process. Comfort feature 105 can be a layer of for example, an encased silicone or gel material, a spacer fabric or a fiber fill insert. Comfort feature 105 allows the distribution of the weight of the breast tissue over the width of the strap 100 located at the top of the wearer's shoulder and minimizes the pressure of the breast tissue on the shoulder during wear. Comfort feature 105 together with non-slip portion 110 of PORON™ also offer a degree of compressibility and therefor comfort to the wearer of the brassiere incorporating such a strap 100. Comfort feature 105 can have either a straight or a curved configuration similar to the first and second embodiments shown in FIGS. 2 and 3 and FIGS. 6, 7a, and 7b, respectively.
A fourth embodiment of the present invention, a non-slip strap is shown in FIGS. 9 and 10, and generally referred to using reference numeral 120. Strap 120 has a non-slip portion 125 that is knitted to enhance the friction between strap 120 and the skin of the shoulder of the wearer to prevent unwanted movement during wear. Strap 120 has a non-slip portion 125 that is knitted using an elasticized material that is plated towards its surface 126. By knitting the elasticized material to the surface 126, a nap is created to provide a gripping or friction effect between strap 120 and the skin of the wearer to prevent slipping. The material used to knit non-slip portion 125 is a blend of preferably approximately a 36% nylon and 64% Spandex blend material. Other similar percentages could also be used to provide the same function to prevent slipping between non-slip portion 125 and the skin of the wearer.
Strap 120 preferably has a straight configuration; although other configurations, such as an elongated ovoid shape, could also be used to enhance the functionality of strap 120. A strap having a narrower and/or straight configuration would coordinate with a delicate brassiere and still offer the non-slip function. The manufacturing of a straight strap is more efficient because the cutting and sewing processes are shorter and simpler. A strap having a thickness of from 0.375 inches to about 1.25 inches is sized to provide optimal performance. Non-slip portion 125 is connected to a base material 130 by stitches 135. Additionally, strap 120 could also include a comfort feature as shown in the second embodiment to provide additional comfort to the wearer.
