The present invention relates generally to a garment formed to provide increased comfort, support, and/or flexibility to the user. In particular, the present invention relates to a brassiere that provides a stretchable and/or customized fit to accommodate differently shaped and/or sized body portion(s) across different shape and/or size groups to enhance comfort, support, and/or flexibility to many different users.
Garments are typically made in standard shapes and/or sizes, each of which is intended to fit a group of users having similar body shapes and sizes. Within any shape and/or size group, the intended users may nevertheless have somewhat different heights and/or weights. As a result, the standard shape and/or size system cannot comfortably fit all users in the same shape and/or size group. This is particularly true when the garments are designed to fit closely on the users' bodies.
For example, brassieres are available in standard band sizes (e.g., 32 to 42 inches) and cup sizes (e.g., AA to DD) to accommodate women of different body shapes and sizes. Brassieres of a selected band and/or cup size are intended to fit not only users of that particular shape and/or size but also those whose actual bodily dimensions may fall between two standard shapes and/or two standard sizes. In view of this phenomenon, the standard shapes and/or sizes will not comfortably fit all users.
Custom tailoring is a conventional technique used to fit a garment to a specific user by first measuring the user, and then making, or modifying, the garment according to the measurement. Although custom tailoring can be employed to address the above-mentioned problem, the cost and effort associated with custom tailoring makes it impractical to supply to the mass market.
The present invention provides a garment that can be formed according to a standard shape and/or size system, yet capable of providing a stretchable fit to accommodate different shapes and/or sizes occurring across different shape and/or size group without significantly increasing cost. In particular, the present invention provides a brassiere that self-adjusts to a variety of different shape and size users, while also providing the ability to continuously self-adjust to that particular user when that user's body changes shape and/or size such as when the wearer bends her body during various physical activities or changes occurring during natural physiological cycles, while enhancing comfort, support, and/or flexibility to the user.
The present invention relates generally to a garment that provides additional comfort, support, and/or flexibility to users across different shape and/or size groups. For example, the garment can be in the form of a brassiere having bra cups defined at least partially by a bra rim. Each of the bra cups includes an outer stretchable layer and an inner layer, and a bra wing supports the bra cups on a user. A stretchable component is located on each of the bra cups adjacent to at least a portion of the bra rims and attached to the inner layer. The stretchable component is made from a stretchable fabric and has a stretchability greater than the inner layer and less than the outer layer. The inner layer, the outer layer and the stretchable component are structured so as to allow the bra cups to expand to accommodate differently shaped and/or sized body portion(s) across different shape and/or size groups.
According to a further aspect of the present invention, the brassiere can also have the bra wings and bra straps made of a stretchable fabric similar to the outer layer of the bra cups. This will allow the bra wings and bra straps expand to accommodate users across different shape and/or size groups.
The inner layer, bra wings and bra straps are preferably made from a stretchable fabric containing a fiber that has a high elongation and a low hysteresis, thereby providing a fabric with optimum stretching with less force and greater recovery power. This results in the wearer experiencing little or no perceptible resistance to stretch movements, as well as a quick shape recovery so as to closely conform to the body of the wearer. It will be appreciated that the stretchable fabric can be knitted or woven or in the form of lace, embroidery, mesh, and the like.
For the purposes of illustrating the present invention, there is shown in the drawings an illustrative form, it being understood however, that the invention is not limited to the precise form shown by the drawings in which:
Referring now to the drawings where like numerals indicate like elements, a brassiere constructed in accordance with the principles of the present invention is shown and designated generally as 10. In the various embodiments illustrated, the garment of the present invention is shown as a brassiere 10. However, the present invention is not limited to brassieres 10 and can be incorporated into other garments, including, for example, briefs, tops and other types of shapewear. Additionally the exemplary brassieres 10 shown in the drawings are not to be considered limiting in any manner. It will be appreciated that the various features described herein may be used singly or in any combination thereof.
In the embodiment illustrated in
If desired, the brassiere 10 can be formed with one or more supporting elements to provide additional support to the user. For example, one or more shoulder straps 16 can be provided and joined to the bra cups 12 and the bra wing 14 in various conventional manners. A bra underwire 18 (visible in
The bra cups 12 are preferably formed so as to have a multi-layer structure, such as including outer layers 12a and inner layers 12b. In the preferred construction, the outer layers 12a and the inner layers 12b are attached to each other only along the outer edges, or periphery, of the bra cups. This allows each of the outer and inner layers to move freely with respect to each other within almost all of a region contacting the wearer. This assists the fabric layers to more easily conform to the individual shape and/or size of the wearer.
The outer layer 12a is preferably made of a fabric containing a fiber that has a high elongation and a low hysteresis, thereby providing a fabric with optimum stretching with less force and greater recovery power. As a result of the low force required for stretching, the wearer experiences little or no perceptible resistance to stretch movements. As a result of the low hysteresis characteristic of the fabric layer material, the fabric quickly recovers its shape and closely conforms to the body of the wearer. That is, the fabric of the outer layer 12a conforms and maintains contact with the body of the wearer throughout a wide range of movements by the wearer. A non-limiting example of an elastomeric fabric that is applicable to the present invention is fabric containing LYCRA® T902C spandex. LYCRA® T902C spandex is a co-polyether-based, clear spandex with high elongation and relatively flat stress/strain behavior. Such a fabric can be composed of a nylon/elastane material blend, for example, a 58% nylon/42% elastane fabric available from Best Pacific Textile Ltd. as item number 12765MS1.
The material of the outer layer 12a preferably has an elongation in a range from about 95% to about 153% in either or both of the length and width directions under an 8.8 lb load. In another example, the fabric of the outer layer 12a also preferably has a modulus in the range from about 1.2 to about 2.1 when the elongation of the material is about 40%.
The inner layer 12b can be formed from a material that is less stretchable than the outer layer so as to provide a desired shaping effect to the user. In one example, the inner layer 12b can include a padding material, such as a foam material with a polyester fabric liner, to provide a desired shape and enhanced support to the user. In yet another example, the inner layer 12b can be a semi-rigid fabric that has a limited stretchability, i.e., a limited elongation and/or modulus, to maintain the predetermined shape of the fabric. Such a fabric can be composed of a nylon/elastane material blend, for example, a 72% nylon/28% elastane fabric available from Ruey Tay as item number D3051. The material of the inner layer 12b also preferably has an elongation in a range from about 0%, where the material is substantially non-stretchable, to about 115% in either or both of the length and width directions under a 10 lb load. The material of the inner layer 12b also preferably has a modulus in the range from about 1.5 to about 2.6 when the elongation of the material is about 40%.
A stretchable component 24 is also provided on the inner portion of the bra cup 12, and attached between the inner layer 12b and the bottom bra rim 22. The stretchable component 24 is preferably formed of a material that is more stretchable than that of the material forming the inner layer 12b, such as a power mesh fabric available from Ruey Tay under item number 16006SR. The material of the stretchable component 24 preferably has an elongation in a range from about 50% to about 130% in either or both of the length and width directions under an 8.8 lb load. The material of the stretchable component 24 also preferably has a modulus in the range from about 0.9 to about 2.5 when the elongation of the material is about 30%. The stretchable component 24 so formed can expand to provide a stretchable fit to different shaped and/or sized body portions across different shape and/or size groups while allowing the inner layer 12b to remain substantially unchanged and to maintain its predetermined shape.
The stretchable component 24 can also be formed into various shapes and sizes. In one example, as shown in
The stretchable component 24 can be joined to the other portion(s) of the brassiere 10 in various ways. For example, the inner layer 12b, the stretchable component 24 and the bottom bra rim 22 can be sewn together by various conventional methods, or formed as a single piece of material but with different (i.e., varying) stretchabilities. It will be appreciated that the stretchable component 24 can be formed and/or joined to the bra cups 12 in various other ways, such as attachment directly to the wire channel 20, which are also within the scope of the present invention.
The elongations of materials discussed herein were measured under the noted load during the third cycle at the outgoing stretch, similar to the various test procedures specified in the ASTM D4964 Standard. As will be understood, the aforementioned elongation or modulus ranges are merely examples and are not limiting.
The bra wing 14 of the brassiere 10 can be formed in various manners. For example, the bra wing 14 can be formed as a single continued piece (not shown) or two separate pieces releasably joined to each other. Each bra wing 14 can have front and rear end portions 26 and 28. Each of the front end portions 26 of the bra wing 14 can be adapted to join to one of the bra cups 12 in various manners. The rear end portions 28 can be adapted to join to each other in various ways, such as by various fasteners 30. In another embodiment, the single continuous wing (not shown) can have its free ends joined to the bra cups 12, which are releasably joined to each other in the front of the brassiere. It will be appreciated that various the bra wing 14 can be formed in various other manners, which are also within the scope of the present invention.
As described above, the inner layer 12b is less stretchable than the stretchable component 24 and less stretchable than the outer layer 12a, and the outer layer 12a is preferably the same as or more stretchable than the stretchable component 24. The bra wing and optional shoulder straps are also preferably formed of a fabric containing the same stretchable fiber as the outer layer 12a. This combination of stretch characteristics in the fabrics of the various brassiere components unexpectedly provides a brassiere with a stretchable and/or customized fit that accommodates differently shaped and/or sized body portion(s) across different shape and/or size groups to enhance comfort, support, and/or flexibility to many different users.
There are many unexpected advantages to the above-described construction. Namely, the use of the fabrics in the inner layer, outer layer, stretchable component, bra wing and straps creates a brassiere that fits many users across different shape and/or size groups. For example, brassieres can be made in a standard sizes 34B, 34C and 34D, and comfortably flex and self-adjust to fit wearers across sizes 34A, 36A, 32C and 34B (for the 34B size); across sizes 34C, 36B, 38A and 36C (for the 34C size); and across sizes 34D, 36D, 34D and 38C (for the 34D size). This in turn allows a manufacturer to greatly reduce the number of items in the product line, and thus significantly reduce manufacturing costs.
Although the above description of the present invention is made in connection with an exemplary article of garment in the form of a brassiere, one skilled in the art will appreciate that the present invention is applicable to various other articles of garments including, but not limited to, briefs, tops and other shapewear garments.
