1. Field of the Invention
An athletic bra with an exoskeleton support structure including an adjustable compression strap and molded cups to both encapsulate and compress the breasts to maximize support, comfort and motion control during athletic activities.
2. Background of the Invention.
Women participating in athletic activities have long needed appropriate athletic bras to protect delicate breast tissue from damage and stretching due to inadequate support, excessive motion and bounce while at the same time providing comfort during all activities. There is also a need to compress and encapsulate the breasts to inhibit the bouncing motion inherent in running or jumping activities. Encapsulation provides support and breast separation. Compression of the breasts may also be preferred to prevent the breasts from impeding or interfering with certain movements, such as a golf swing.
In addition to these functional attributes, an athletic bra must also meet the subjective criteria of fit and comfort. Even though women come in all shapes and sizes, and even differing shapes in the same size, some typical athletic bras provide no adjustment at all and are offered only with Small, Medium, Large sizing. Other athletic bras which are sized by rib and cup sizes, only mirror the sizing and fit offered in regular bras and offer only the chest circumference adjustment and shoulder strap adjustments as regular bras.
Some typical athletic bras offer some amount of support to female athletes by providing as much compression as possible in the hopes that bringing the breasts as close to the body as possible will minimize bounce. These bras may accomplish maximum compression, but do not address encapsulation for comfort or aesthetics at all. Many of the Small, Medium or Large compression bras which generally have no adjustments are little more than tank tops made of elastic material sized to compress the breasts of the wearer. In general, typical athletic bras err on the side of comfort thereby sacrificing motion control and support. In addition, these tank-type bras leave a lot to be desired in aesthetics since they generally result in a single compressed mass across a woman's chest with no hint of supporting the breasts individually. A functional shortcoming of tank-type bras is that both breasts end up moving together which can mean more motion than necessary for some athletic activities. For many high intensity and/or high impact activities it is desired to provide motion control for each breast separately to avoid excessive bounce and unnecessary motion and transmission of motion between the breasts. Excessive bouncing can be painful and result in damaged and stretched breast tissue. Forcing both breasts to move together only compounds the problem by imparting motion to a larger mass.
A typical athletic bra of an appropriate size provides only one type of fit and support to the wearer. As a result, most women must possess a stable of different athletic bras depending on the activities in which they participate. Most light weight bras while comfortable are not likely to provide sufficient support, and those bras that provide sufficient support are likely to be heavy weight and uncomfortable.
One prior art bra called the “Shock Absorber” includes an inelastic band that is part of an H-shaped arch on the front extending from the outer side of one breast to the outer side of the other breast. The band appears to extend across the chest from one shoulder strap to the other above the breasts. The arch is not adjustable and is anchored at the sides of the rib band, at the straps and the tops of the cups. It is intended to provide some measure of motion control. However, the inelasticity of the band and lack of support, breast separation and adjustment do not address the fit and comfort criteria. Moreover, while the band may achieve a certain degree of motion control, there is no provision at all for individual encapsulation of the breasts.
Another shortcoming of some prior art bras concerns the materials used and the construction. Although cotton and cotton blends are comfortable materials when dry, they can become heavy and irritating when a wearer perspires during activities. In addition, the elasticity of these materials may be adversely affected by wetness. The prior art has addressed this material problem by using various polyester and other moisture control fabrics. The construction, however, has remained the same: either one uniform material throughout, or different materials and layers pieced together in a typical cut-and-sew construction. A single uniform material will not provide opportunities to customize areas of the bra for elasticity or inelasticity. In bras pieced from multiple pieces of fabric, the exposed sewn seams are often a source of chafing, skin irritation, itching and other discomforts to the wearer.
The athletic bra of the present invention is different from the prior art in a number of ways. In one aspect of the invention, the athletic bra of the present invention is made of an entirely different construction than prior art bras in the use of an exoskeleton anchoring the cups in the front of the bra. In another aspect of the invention, the bra with the exception of the cups is made of a contiguous engineered laminated material that provides a personal fit by utilizing stretch, non-stretch and reinforcement zones as needed in different areas of the bra.
As for construction, an exoskeleton forms the main structure of the front of the bra onto which the molded cups are attached. The exoskeleton refers to the front framework of the bra that surrounds the cup area and extends across the chest from underarm to underarm, under each breast and meeting in the center. The exoskeleton includes an integral lower chest band and cup periphery onto which the cups are attached. In some embodiments, the exoskeleton also includes a top compression band. The chest band or rib band extends all the way around the ribs and may include a back closure. Attached to the top of the exoskeleton and the rear of the chest band are the shoulder straps. The chest band, top compression band and the shoulder straps are fully adjustable in most sizes of the bra. Molded cups are attached to the exoskeleton frame to complete the bra. Each of the adjustment areas comprise a hook which is selectively anchored to adjustment slots or perforations along the strap and/or band. To maximize the amount of adjustment, a number of adjustment points are provided along each strap.
The material used for the various portions of the athletic bra of the present invention can be thought of as an additional construction element of the bra. The exoskeleton is made of an engineered laminated material having an outer fabric layer, a middle fabric layer and an inner fabric layer which are bonded to each other using a bonding material interposed between each fabric layer. Depending on the area of the bra, the laminated material is modified to provide stretch or non-stretch properties or reinforcement.
One aspect of the invention is to provide an athletic bra with multiple adjustment points to provide a personal fit, enhanced comfort and support. To this end, the rib band includes several slots into which the back hook can be engaged to provide a wide range of rib band adjustment. The shoulder straps are also adjusted by providing hooks on the back of the rib band. Each hook can be received in a series of adjustment slots provided along the rear of each shoulder strap. The Y-shaped element extending along the tops of the cups and forming the top of the exoskeleton is a compression strap or band which attaches to the center front of the chest band. The vertical portion of the compression strap extends downward between the cups to separate the breasts. The compression strap is also adjustable using a hook and series of adjustment holes into which the hook is received. The multiple adjustments of the present invention provide customizable fit and level of comfort and compression depending on the activity of the wearer. For example, for higher impact activities, the wearer may choose to adjust the compression strap tighter to provide more compression than for lighter impact activities.
Another aspect of the invention is to provide an athletic bra that merges the objectives of encapsulation of the breasts and compression of the breasts for enhanced better motion control and support during physical activities. The molded cups are formed of a two layer material in which the two layers are not bonded through most of the cup area except at the periphery. The inner and outer layers are configured to separate the breasts by individually encapsulating each breast to isolate breast motion, thereby reducing unnecessary transmission of motion to both breasts as is the case with most prior art bras.
Other configurations, features and advantages of the invention will be, or will become, apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features and advantages be included within this description, be within the scope of the invention, and be protected by the following claims.
The invention can be better understood with reference to the following drawings and description. The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. Moreover, in the figures, like reference numerals designate corresponding parts throughout the different views. In the drawings:
Athletic bra 10 comprises an exoskeleton 12 and molded cups 14 forming the front of the bra. Broadly, the exoskeleton is the front portion of the bra upon which the cups are attached. In the embodiment shown in
Chest band 16 extends around the entire circumference of the wearer's ribs as seen in
Shoulder straps 20 are formed integrally with the chest band and extend upward from the front and over the shoulders. In the embodiment shown in
Fixed length, non-adjustable shoulder straps may be employed as well. This is particularly true when the bra is made in a pull-over style. It may also be true if the bra is constructed for smaller bust sizes.
Directional compression strap 18 has a flattened Y-shape and extends across the tops of the cups from shoulder strap to shoulder strap. The vertical leg extends downward between the cups to attach to the chest band and thereby separate the breasts. The attachment of the vertical leg to the chest band may be fixed. Alternatively, this attachment is adjustable as shown in
In the context of this application, the “framework” refers to the bra without the molded cups. That is, the framework comprises the exoskeleton, the sides and back of the rib band and shoulder straps. As can be seen from the drawings with the exception of the compression strap, the framework is made from a contiguous piece of engineered material. The framework may be constructed of multiple pieces of material but they are bonded to one another so as to provide a contiguous inner layer and a contiguous outer layer.
Molded cups 14 are attached to exoskeleton 12 and are designed to encapsulate each of the breasts separately. The molded cups, the exoskeleton and the material are designed and work in tandem to provide both encapsulation and compression of the breasts. To fully explain this two-fold function, a description of the novel engineered laminate material is necessary.
The engineered laminate can be thought of as another structural component of bra 10. The material has a number of zones providing varying degrees of stretch and/or reinforcement depending on the location. For purposes of this description, “low stretch” generally refers to materials with 1-10% lycra content; “medium stretch” refers to materials with 10-20% lycra content; and “high stretch” refers to materials with over 20% lycra content. It will be understood by a person of ordinary skill that higher lycra content corresponds to higher recovery power when stretched. In other words, higher lycra content results in a material that requires more energy to pull apart, and therefore higher recovery power. “Non-stretch” refers to materials with no elastic components and therefore negligible stretch characteristics. That is, the material itself is non-stretch and any limited stretch exhibited is a result of mechanical movement in the weave of the fabric.
The material zones of the bra will be described in detail below. Each zone has at least two layers of material. Referring to
Molded cups 14 are made of only two layers molded at different depths. For the molded cups, outer layer 40 is the same material as the rest of the bra and is molded to be shallower than the inner layer. The layers in the cups are not bonded to each other except at the periphery of the cups where they are attached to the exoskeleton. Inner liner 39 has a softer feel as it is in contact with the most delicate tissue, and also has limited or minimal stretch characteristics. Inner liner 39 is made of a low stretch material such as a stretch polyester warp knit. Since inner liner 39 is less elastic than outer layer 40, molding the inner liner to be deeper results in the less elastic material firmly encapsulating the breast. The shallower outer layer which is more stretchable enhances the compression of the breasts to provide motion control. Compression and encapsulation are further enhanced by the exoskeleton as described below. One advantage of the different molding depths of the inner and outer layers is that the shallower outer layer results in a more attractive retail appearance when the bra is displayed on a hanger because the outer layer retains a tighter shape and provides a smoother appearance.
In most areas of the bra with the exception of the molded cups, the material comprises inner and outer layers 38, 40 with at least one additional middle layer 42 interposed therebetween. Middle layer 42 may be stretch or non-stretch depending on the characteristics desired at a particular location of the bra. These three layers are laminated together by way of bonding layers 44 which are interposed between the each pair of facing fabric layers,
In some areas of the bra framework middle layer 42 is a non-stretch material. Referring to
The areas of the bra framework in which middle layer 42 is a stretch material are the top and lateral perimeters of each of the molded cups; and the rib cage band from the underarms around to the back closure. In these areas middle layer 42 is preferably a high stretch power mesh material. The stretchiness of these portions of the framework around the molded cups enhances the fit of the bra around the breasts and enhances the encapsulation of each breast.
In certain zones of the bra framework, another middle layer, reinforcement layer 43 is also placed and bonded between inner and outer layers 38, 40, in addition to middle layer 42,
The stretch and non-stretch zones can be adjusted or changed as necessary for the size of the bra, the level of anticipated activity of the wearer and to enhance fit and comfort.
Although bonding layers 44 are depicted in
The engineered laminated material is lightweight, strong, breathable and supportive. In addition, the performance characteristics of the laminated material can be altered by adding a reinforcement ply. Indeed, even in a contiguous piece of material as is used for the bra framework, different portions of the material can be engineered to exhibit different characteristics based on the materials used in the middle of the fabric “sandwich.” Another advantage of the laminated material over traditional cloths is that the bra framework can be seamless and unitary. The inner layer of the bra framework that lies against the skin is smooth and contiguous. A preferred method of constructing the bra is to bond the materials together to eliminate as many sewn seams as possible. One preferred embodiment of the bra has no sewn seams at all. The invention contemplates the use of some sewn seams. It is understood that elimination of any sewn seams, bindings or hem stitching on the bra means elimination of the main sources of chafing and irritation.
The independent functions of encapsulation and compression of the breasts is accomplished in the present invention by both the materials used and the construction of the bra. As described above, the breasts are individually encapsulated by the molded cups. Separation is also ensured by way of compression strap 18 which puts a physical barrier between the two breasts. It has been found that individual encapsulation provides independent motion control to each breast, thereby reducing the motion imparted to the breasts by prior art bras by treating the two breasts as a single mass. Compression of the breasts is accomplished by the molded cups and the unique molding of the inner and outer layers. The horizontally oriented portions of compression strap 18 provide an added measure of motion control. Adjustment of compression strap 18 by engagement of hook 34 into a higher or lower set of perforations 36 results in a customized.
The bra framework and molded cups are preferably attached together by bonding. In this way no sewn seams are present which can sometimes increase the likelihood of chafing points along the bra. Of course, the exoskeleton and molded cups may be sewn together as well.
A detailed look at the interior of exoskeleton 12 and molded cups 14 is shown in
Fit and support in an athletic bra include both objective and subjective measures. The objective side includes the measured size of the wearer and the amount of motion control which may be monitored by wear testing and plotting motion of the breasts during activity. The subjective side is the wearer's experience while wearing the bra and engaging in athletic activity. Encapsulation of each breast individually and compression of the breasts to achieve motion control improves the fit and support of the bra both objectively and subjectively.

The bra depicted in
It is within the scope of the invention to combine the various alternatives described above in any number of permutations. For example, the bra may have an adjustable compression strap on the exterior as seen in
The stretch or non-stretch areas described herein refer to one or more preferred embodiments. Depending on the size, the activity level and other factors, the athletic bra of the present invention may be designed with alternative stretch and non-stretch areas. The use of a multi-layered laminated material with layers exhibiting different stretch properties to result in an amalgamated stretch property for the laminated material in any particular area or zone of the garment is contemplated to be within the scope of the present invention.
Athletic bra 10 shown and described is designed for an average C-cup woman. In the United States, 36C is the average bra size. Size 34B is the smallest size that would be made with the exact construction shown in the accompanying drawings. Smaller sizes may have thinner straps; may be made of different material or have less points of adjustment. Larger sizes would have the same points of adjustment, but be made with extra layers in the engineered material; more heavy duty materials; heavier weight materials; or have different transition points between the non-stretch and stretch areas; an extra adjustment notch in the compression strap to enable further compression.
While various embodiments of the invention have been described, it will be apparent to those of ordinary skill in the art that may more embodiments and implementations are possible that are within the scope of the invention.
