This specification describes bras that provide a high degree of support during activities that are associated with high impact.
Surveys have indicated that bras have a number of drawbacks, chief among them the difficulty in putting them on and off Another difficulty highlighted in surveys is that they are often too tight or too loose in the chest band. Still another drawback with bras according to surveys is the discomfort experienced due to the weight of the bra pulling on the shoulders and the neck, which can cause cutting into skin. Still another drawback with bras according to surveys is nipple show-through. Moreover, there continues to be a need for improved support and comfort.
Addressing these deficiencies is complicated by the fact that many women have breast asymmetry and that the breast does not contain muscle but rather is comprised of fat and glandular tissue. Addressing these deficiencies is further complicated by the fact that breast movement is complex, with the breast being capable of moving along three different orthogonal axes depending on activity, and the way in which the weight of each breast is distributed differently.
Given the above-background, what is needed in the art are improved bras to overcome the above identified deficiencies. Such improvements will have the benefit of empowering women. That is, achieving a central goal of enabling every woman to be confident and feel comfortable without limits or distraction.
The present disclosure addresses the above-identified deficiencies. In the present disclosure bras that provide cantilevered support, as opposed to relying solely on suspension support, are provided. In some embodiments this cantilevered support is provided by encapsulation of breasts, which separates the breasts and treats them as two separate masses, as opposed to compression of the breasts, which compresses the breasts into a single mass and thereby treats the breast, from a support perspective, as this single mass. Moreover, in some embodiments, the presently disclosed bras provide for a reduction in acceleration. In such embodiments, all breast movement is not hindered. However, such embodiments of the present disclosure are able to reduce breast acceleration resulting in a minimization of the amount of pain that is experienced when wearing the disclosed bras.
A bra of the present disclosure includes a band that wraps around a torso of a wearer. The band includes a back portion, a first underarm portion, a second underarm portion, and a front portion. The front portion is connected to the back portion through both the first underarm portion and the second underarm portion. Additionally, the band includes a first cup region and a second cup region. A channel runs below the first cup region and the second cup region, and the channel is formed between an inner fabric and an outer fabric (e.g., an inner fabric and an outer fabric of the band). A gore is formed above the channel and between the first cup region and the second cup region, which adjoins the first cup region and the second cup region together. Moreover, a molded cradle, which has at least a first curvature with respect to a first plane, is fitted into the channel. Each tessellated encapsulating bra cup includes a plurality of tiles, and is fitted into the corresponding cup region. Respective tiles in the plurality of tiles that are further away from the molded cradle, that is further away from a bottom portion of the band, are larger in size than respective tiles in the plurality of tiles that are closer to the molded cradle, or closer to the bottom portion of the band. This, in itself, provides for a novel basis for cantilevered support. Furthermore, each tessellated encapsulating bra cup has a generally concave inner face and a generally convex outer face. Altogether, the tessellated encapsulating bra cups collectively contribute unparalleled novel cantilevered support to the bra.

Moreover, the first backing member is bonded, or sewn, to a terminal face of the first shoulder strap. A mating touch fastener component includes a second backing member that supports a second plurality of engagement elements. This second backing member is bonded, or sewn, to a base position of the first shoulder strap on the same side as the touch fastener component. A strap loop is secured to a terminal position of the second shoulder strap, and is configured to receive and loop through the shoulder loop so that the first plurality of engagement elements engages a subset of the second plurality of engagement elements to releasably fasten the left touch fastener component to the left mating tough fastener component. This adjusts a tightness of the first left strap and the second left strap on a torso. In some embodiments, the corresponding touch fastener and mating fastener of each shoulder strap are adjustable.
In some embodiments, the mating fastener and the touch fastener of each strap are magnetized. For instance, in some such embodiments, the mating fastener and the touch fastener of each strap are each magnetized with a corresponding single neodymium magnet. In other embodiments, the mating fastener and the touch fastener of each strap are each magnetized with a corresponding plurality of neodymium magnets. In still other embodiments, the mating fastener and the touch fastener of each strap are each magnetized with a corresponding array of neodymium magnets that effect a first twist on and twist off releasable attachment of the corresponding first strap to the corresponding second strap.
In some embodiments, a third textile strip is affixed to an inner facing surface of the upper portion which is above each cup region. The third textile strip is configured to adhere to a surface of a torso when the third textile strip, or the surface of the torso, is damp. In some such embodiments, the third textile strip is between 0.5 centimeters and 2.0 centimeters wide.

In various implementations, the band 102 is formed from a single ply of fabric.
Likewise, in other implementations, the band 102 is formed from a double ply, or two-ply, of fabric, from a three-ply of fabric, from a multi-ply of fabric or, in further implementations, from a combination of plies. For instance, in some implementations a first portion of the band 102 is formed from a first ply of fabric (e.g., the front portion of the band and the back portion of the band are formed from a two-ply fabric), while a second portion of the band 102 is formed from a second ply (e.g., the underarm portions of the band are formed from a single-ply fabric).
Similarly, in various implementations the band 102 is formed from a single type of fabric. Likewise, in other implementations the band 102 is formed from a variety of fabrics. For instance, in some implementations the first underarm portion of the band 102, the second underarm portion of the band, and the back portion of the band are formed from a first fabric (e.g., formed from a fabric that includes a cotton and a polyester blend), while the front portion of the band is formed from a second fabric (e.g., formed from a wool felt fabric). Additionally, in some implementations the band 102 is formed from a single layer of fabric. In other implementations, the band 102 is formed from at least two layers of fabric (e.g., an inner fabric 1502 and an outer fabric 1510 of
In various implementations, the band 102 includes corresponding cup regions (e.g., cup regions 104 and 106). These cup regions (104, 106) are utilized to support, surround, lift, and/or cover the breasts of the wearer. In some implementations, the cup regions (104, 106) also provide an ornamental effect on the bra 100, which includes at least a shape of the cup regions and a texture of the fabric of the cup regions. In various implementations, and with reference to

Referring back to
A gore 110 is formed above the channel 108 and between the first cup region 104 and the second cup region 106. The gore 110 is configured to adjoin the first cup region 104 and the second cup region 106 together, forming a bridge there between. In some implementations, the gore 110 is formed from an elastic fabric such as an elastic yarn knit, whereas in other implementations the gore is formed from a relatively inelastic fabric, such as cotton. During use, the gore 110 lies flat against and abuts a chest of the wearer, in between the breasts.
In various implementations, a molded cradle 130 (e.g., the molded cradle 130 of
In order for the cradle 130 to rest comfortably against the wearer, the cradle is formed of a flexible material. Moreover, in some implementations the cradle 130 is formed via an additive manufacturing process in some embodiments. For instance, in some implementations, the cradle 130 is formed via injection molding. In other implementations, the cradle 130 is formed via a three-dimensional printing process such as fused deposition modeling (FDM), stereolithographic (SLA), or selective laser sintering (SLS). Materials used to form the cradle 130 in various embodiments of the present disclosure include thermoplastic elastomers (TPE) such as thermoplastic rubbers and resins, a variety of foams such as auxetic foam or polyurethane foam, a variety of plastics (e.g., polylactic acid (PLA) and polyvinyl alcohol plastic (PVA)), as well as silicon. For instance, thermoplastic elastomers and resins include a styrenic block copolymer, a thermoplastic polyolefinelastomer, a thermoplastic vulcanizate, a thermoplastic polyurethane, a thermoplastic copolyester, or a thermoplastic polyamide. These materials and other materials that form various components and portions of the bra 100 will be described in more detail infra.
In the Figures, reference number 106-1 delineates a cutout of the corresponding cup region (104, 106) in order to depict internal details of the bra 100. As such, it will be appreciated that that cutout 106-1 is not actually found in bras of the present disclosure.
In various implementations, each cup region (104, 106) and the gore 110 combine to create a neckline on the front portion of the band 102. As described supra, each cup region (104, 106) is formed in any of a variety of shapes (e.g., a padded shape, a petite shape, a push-up shape), and, in collective combination with the gore 110, is responsible for forming a shape of the neckline. In some implementations, the shape of the neckline is formed by the band 102. The shape of the neckline includes shapes such as a full neckline, a part-full neckline, a balconette neckline, a half-cup neckline, a plunge neckline, etc. As will be described in more detail infra, the shape of the neckline in various implementations of the bra 100 is largely ornamental since a significant portion of support for the breasts is borne by other portions (e.g., the cups) of the bra.
As shown in
In various implementations, these tiles 122 of the tessellated cups 120 have a variety of shapes (e.g., triangular, quadrilateral, pentagonal, hexagonal, etc.) that is dependent on the shape of the cup, a location of the corresponding tile, a desired ornate effect, or a combination thereof. For instance, in some implementations, each tessellated cup 120 includes a first outer boundary (e.g., outer boundary 121 of
In various implementations, the tiles 122 are formed in a variety of sizes. The size of each tile 122 is dependent on the shape of the cup, a location of the respective tile, a desired ornate effect, or a combination thereof. For instance, in some implementations respective tiles 122 that are further away from the cradle 130, or a bottom portion of the band 102, are larger in size than respective tiles that are closer to the cradle, or the bottom portion of the band. Similarly, in other implementations each tile 122 has an identical size (e.g., a grid of squares, an array of circles). This change in size of the tiles 122 relative to a corresponding distance from a bottom portion of the bra 100 provides not only a portion of the support for the breasts through deformation of the tiles, but also has a visually pleasing, ornamental effect.
Moreover, in some implementations, each edge portion of each tile 122 is an approximate straight line. In other implementations, each edge portion of each tile 122 has a slight curvature. In some implementations, each edge portion of each tile 122 is either an approximate straight line or has a slight curvature.
In various implementations, and as illustrated in at least
In some implementations, each tessellated cup 120 is formed as an embroidery on an exterior portion of each respective cup region (104, 106). In some implementations, the embroidery of each tessellated cup 120 includes embroidering the entire respective tessellated cup 120. However, the present disclosure is not limited thereto. For instance, in some implementations a portion of each tessellated cup 120 is formed as an embroidery (e.g., a bottom end portion of each tessellated cup is formed as an embroidery). Furthermore, in some implementations each tessellated cup 120 is formed as described above with respect to the hollowed and/or solid tiles 122, and an embroidering of the underlying tessellated cup is formed on an exterior portion of each cup region (104, 106). The embroidering of the underlying tessellated cup 120 includes embroidering each tessellated cup 120 in its entirety as well as embroidering only a portion of each tessellated cup. For instance, in some implementations each cup region (104, 106) includes a respective tessellated cup 120 and only a portion of the respective tessellated cup 120 is embroidered on an exterior portion of the respective cup region. Furthermore, in some implementations one or more layers of material interpose between the embroidering of the tessellated cup 120 and each respective cup region (104, 106). The one or more layers of material that interpose the tessellated cup 120 and each respective cup region (104, 106) includes materials such as cotton, lace, mesh, nylon, polyester, silk, spandex, and the like. In some implementations, each respective cup region (104, 106) includes one or more respective layers of material that interpose the tessellated cup 120 and each respective cup region (e.g., a discrete first layer of material for a first cup region 104 and a discrete second layer of material for a second cup region 106). In some implementations, the embroidery of each tessellated cup 120 is flush with each respective cup region (104, 106) (e.g., a difference in height between the embroidery and a respective cup region is less than or equal to 0.1 millimeters (mm)). In some implementations, the difference in height between the embroidery and a respective cup region is less than or equal to 0.25 mm. In some implementations, the difference in height between the embroidery and a respective cup region is less than or equal to 0.5 mm. In some implementations, the difference in height between the embroidery and a respective cup region is less than or equal to 0.75 mm. In some implementations, the difference in height between the embroidery and a respective cup region is less than or equal to 0.1 mm. In some implementations, the difference in height between the embroidery and a respective cup region is less than or equal to 0.5 mm. In some implementations, the difference in height between the embroidery and a respective cup region is less than or equal to 0.75 mm. In some implementations, the difference in height between the embroidery and a respective cup region is less than or equal to 1 mm. In some implementations, the difference in height between the embroidery and a respective cup region is less than or equal to 2 mm. In some implementations, the difference in height between the embroidery and a respective cup region is less than or equal to 3 mm.
As previously described, various aspects of the present disclosure are directed to providing bras that incorporate cantilever support of the breasts via the tessellated cups 120, instead of supporting the breast via conventional suspension straps over the wearer's shoulders. The tessellated cups 120 allows each breast to independently move as a discrete mass, whereas conventional bras and cups often treat the breasts as a combined singular mass. This separation of the breasts provides exceptional comfort to the wearer while minimizing excessive movement of the breasts during strenuous or high impact activities such as sports. Since each breast is treated as an independent discrete mass that is encapsulated by the corresponding tessellated cup 120 and the respective cup region (104, 106), acceleration of the breast is reduced through deformation of the tessellated cup 120. This encapsulation reduces a degree of movement from an equilibrium position that each breast endures, as well as reducing pain caused incurred by the wearer by such movement. Further, since the tessellated cups 120 do not incorporate any protrusions towards the torso of the wearer, the cantilever support of the breasts is comfortable to the wearer. Additional details and information regarding the mechanics of the tessellated cups 120 and the cantilever support provided therefrom will be described in more detail infra.
In various implementations, the tessellated cups 120 and the gore 110 are formed as a single molded piece. Moreover, in some implementations each tessellated cup 120 is formed as an individual, discrete molded piece. These individually molded pieces are not connected to each other, and were not molded from a common piece. In some implementations, the tessellated cups 120, the gore 110, and the cradle 130 are formed as a single molded piece. In some implementations, the tessellated ups 120 are formed as a single molded piece. These molds and the materials thereof will be described in more detail infra.

The fitting of the various layers of fabric, the pads, and tessellated cups 120 between the outer textile layer 1510 and the inner fabric 1502, or the single inner pad layer 306, is conducted in a variety of fashions. For instance, fitting each tessellated cup 120 into the corresponding cup region (104, 106) is accomplished either by sewing the tessellated cup to the cup region via seams 306 or by bonding the tessellated cup to a fabric of the corresponding cup region. Moreover, in some implementations the various layers of fabric, pads, and tessellated bra cups 120 are sewn between, or bonded to, the outer textile layer 1510 and the inner fabric 1502. In some implementations, the various layers of fabric, pads, and tessellated bra cups 120 are formed integrally with either the outer textile layer 1510 and/or the inner fabric 1502, or the single inner pad layer 306. In some implementations, each tessellated cup 120 is sewn onto an exterior portion of the corresponding cup region (104, 106). In other implementations, each tessellated cup 120 is sewn into an interior portion of the corresponding cup region (104, 106). In some implementations, each tessellated cup 120 is bonded to a portion (e.g., bonded to an interior surface of an inner fabric, bonded to an interior surface of an outer fabric) of the corresponding cup region (104, 106).
In various implementations, the front portion of the band 102 includes a textile fabric. The textile has an interior surface (e.g., inner fabric 1502) that contacts a torso of the wearer, and an exterior surface that opposes the interior surface of the front portion (e.g., outer fabric 1510) of the band 102. Accordingly, each tessellated cup 120 is fitted onto the corresponding cup region (104, 106) on the exterior surface of the textile (e.g., each tessellated cup 120 is disposed on the exterior of the outer fabric 1510). This exposed tessellation configuration allows for the tessellated cups 120 to impart an ornate effect on the bra 100 since the tessellated cups are visible externally to a person other than the wearer.
In various implementations, the bottom portion of the band 102 forms an underhand 112. The underhand 112 provides support for the breasts of the wearer and dampens movement of the bra 100 during use, but does not provide cantilever support to the breasts like the tessellated cups 120. When the underband 112 is present, it is formed below the channel 108. In some implementations, and as illustrated in at least

These various textile strips (302, 304, and 902) in combination with the tessellated cups 120 provide extraordinary comfort to the wearer during high impact activities such as sports. For instance, the various textile strips (302, 304, and 902) ensure that the bra 100 is stabilized against the torso, while the tessellated cups 120 enable individual movement of the breasts.

A gusset 1000, as used herein, is a component of the bra that is intentionally weakened to relieve stress formed in areas surrounding the gusset. The gusset 1000 allows for slight breast movement to give the wearer a natural feeling while wearing the bra 100, but also prevents the bra from moving as a while unit when the wearer is active. In some implementations, the intentional weakening is provided by utilizing materials with different Young's moduli. The Young's modulus is utilized to measure a stiffness of a solid, or approximately solid, material as determined by an experienced stress and strain via a uniaxial deformation of the material. A smaller Young's modulus (e.g., a number closer to zero) describes a material with a low stiffness (e.g., a high extensibility such as small strain rubber which has a Young's modulus of approximately 0.01 to 0.1 Giga-Pascal's (GPa)), while a larger Young's modulus (e.g., a number further from zero) describes a material with a high stiffness (e.g., a low extensibility such as diamond which has a Young's modulus of approximately 1050 to 1210 GPa). For instance, low-density polyethylene has a Young's modulus of approximately 0.11 to 0.86 GPa, nylon has a Young's modulus of approximately 2 to 4 GPa, foam polystyrene has a Young's modulus of approximately 0.0025 to 0.007 GPa, hemp fiber has a Young's modulus of approximately 35 GPa, polyethylene terephthalate (PET) has a Young's modulus of approximately 2 to 2.7 GPa, and polypropylene has a Young's modulus of approximately 1.5 to 2 GPa, to name a few. In some implementations the gusset 1000 has a Young's modulus that is lower than a surrounding fabric (e.g., the fabric of the underband 112 or the band 102). In some implementations, the gusset 1000 has a Young's modulus that is greater than a surrounding fabric (e.g., the fabric of the underband 112 or the band 102). However, the present disclosure is not limited thereto.
In some implementations the intentional weakening in the gusset 1000 is provided by a process of inducing a stress at a predetermined portion of the bra 100. In some implementations, the stress is a physical stress such as a tensile stress, a compressive stress, a shear stress, or a combination thereof. In some implementations, the stress is a material stress such as a predetermined deterioration (e.g., wearing away or abrasion) of the material of the bra 100. In some implementations, the intentional weakening is provided by a process of subjecting a portion of the bra 100 to a heat treatment process of a chemical treatment process.
In some implementations, the gusset 1000 is formed in a portion of the underband 112 that is below the back portion of the band 102. Likewise, in some implementations, the gusset 1000 is formed in a portion of the back portion of the band 102. Additionally, in some implementations the gusset 1000 is formed in a portion of the underband 112 that is below either underarm portion of the band 102. In some implementations, a respective gusset 1000 is formed in the portion of the underband 112 that is below each underarm portion of the band 102. In some implementations, the underband 112 is formed of a first elastic blend, that has a first percent extensibility (e.g., 10 percent) when placed under a first strain (e.g., a longitudinal strain, latitudinal strain, or a combination thereof), and the gusset 1000 is formed of a second elastic blend that has a second percent extensibility (e.g., 20 percent) when placed under the first strain. The extensibility of a material refers to a measure of an ability of a fabric to stretched, or elongated, under a tensile load. The larger the extensibility of a fabric, the more extensible the fabric is. Additional information regarding material engineering and extensibility is found in Zupin et al., 2010, “Mechanical Properties of Fabrics Made from Cotton and Biodegradable Yarns Bamboo, SPF, PLA in Weft,” Woven Fabric Engineering, print, which is hereby incorporated by reference in its entirety. The second percent extensibility is greater than the first percent extensibility, which allows for the gusset 1000 to deform according to a fit of the wearer. For instance, in various implementations, such as the pull-on bra 100 (e.g., bra 100 of
In various implementations, the underband 112 has a first width that is perpendicular to a length of the first elastic blend of the underband 112. Accordingly, the gusset 1000 has a variable width that runs along the length of the first elastic blend of the underband 112, and that tapers between the first width at the first side of the interruption 1002 and is less than the first width at the second side of the interruption 1002. In some implementations, the gusset 1000 has a width that is greater than a centimeter at the first side of the interruption 1002 and a width that is less than a centimeter at the second side of the interruption. In some implementations, the gusset 1000 has a width that is greater than 1.3 centimeters at the first side of the interruption 1002 and a width that is less than 0.3 centimeters at the second side of the interruption. In some implementations, the gusset 1000 is formed in an approximately triangular shape as illustrated in

In various implementations, the mating fastener 1014 of the second backing member 1010 is formed with a longer length than the touch fastener 1012 of the first backing member 1008. For instance, in some implementations a length of the mating fastener 1014 is at least 5 centimeter (cm) while a length of the touch fastener 1012 is at least 1 cm. In some implementations, the length of the mating fastener 1014 is at least 10 cm while the length of the touch fastener 1012 is at least 2 cm. In some implementations, the length of the mating fastener 1014 is at least 4 cm while the length of the touch fastener 1012 is at least 0.5 cm. In some implementations, the length of the mating fastener 1014 is at least 5 cm while the length of the touch fastener 1012 is at least 1 cm. In some implementations, the length of the mating fastener 1014 is at least 6 cm while the length of the touch fastener 1012 is at least 0.5 cm. In some implementations, the length of the mating fastener 1014 is at least 10 cm while the length of the touch fastener 1012 is at least 5 cm. In some implementations, the length of the mating fastener 1014 is at least double the length of the touch fastener 1012. In some implementations, the length of the mating fastener 1014 is at least four-times the length of the touch fastener 1012. In some implementations, the length of the mating fastener 1014 is at least ten-times the length of the touch fastener 1012. In some implementations, the length of the mating fastener 1014 is at least a quarter of a circumference of the band 102, or the underband 102. In some implementations, the length of the mating fastener 1014 is at least a fifth of the circumference of the band 102, or the underband 102. In some implementations, the length of the mating fastener 1014 is at least a tenth of the circumference of the band 102, or the underband 102. This difference in length between the fasteners (1012, 1014) enables a length of the strap 1004, or the underband 112 and/or the band 102 by way of the strap 1004, to be adjusted with a wider range adjustability. The greater the length of the mating fastener 1014, the greater then possible range of adjustment can be utilized using the strap 1004 and corresponding touch fastener 1012. For instance, conventional hook-eye fasteners are limited in range by the number of eyes and hooks, whereas the fasteners of the present disclosure have no such limitations. Moreover, having a shorter touch fastener 1012 reduces a risk of having the touch fastener misaligned with the mating fastener 1014, which may cause discomfort to the wearer of the bra 100. Additionally, in various implementations this different of length between the mating fastener 1014 and the touch fastener 1012 allows for the entire touch fastener 1012 to engage only a portion of the mating fastener 1014.
In various implementations, an intermediate member interconnects and isolates the first backing member 1008 from the terminal face of the first strap 1004. Similarly, another intermediate member interconnects and isolates the second backing member 1010 from the underband 112, or the band 102. When uncoupling the touch fastener 1012 from the mating fastener 1014, vibrations (e.g., sound waves) propagate through the various materials of the fasteners (1014, 1012) and the bra 100, which in turn produces an amplified vibration, or wave. The various materials of the fasteners (1014, 1012) and the bra 100 act as amplifier for the vibrations to produce any audible noise. These intermediate members are configured to reduce the noise that is generated when the touch fastener component 1012 is disengaged from the mating touch fastener component 1014, by dampening and dissipating these vibrations before the vibrations propagate through the fasteners (1014, 1012) and the bra 100. This dampening ability is realized through both macroscopic properties of the material (e.g., a thickness of the material and a shape of the material) and the mechanical properties of the material (e.g., a porosity of the material or an elasticity of the material). In various implementations, the first intermediate member and the second intermediate member each includes a spandex material, an elastomeric material, a non-woven material, a braided material, a foam material, or a diamond mesh material. In some implementations, the diamond mesh material is formed with threads, or fibers, that align at or between an angle of 30° to 60° from an edge portion of the intermediate member. The material of the intermediate members is selected according to its dampening ability.
In various implementations, the first backing member 1008 and the second backing member 1010 each include an elastic material (e.g., spandex or rubber). The touch fastener 1012 is formed from a knitted material (e.g., cotton or wool) that includes a first plurality of loops. In some implementations, the plurality of loops is formed with a density of at least one hundred loops per square inch. In some implementations, the plurality of loops is formed with the density of at least 500 loops per square inch. In some implementations, the plurality of loops is formed with the density of at least 750 loops per square inch. In some implementations, the plurality of loops is formed with the density of at least 1000 loops per square inch. In some implementations, the plurality of loops is formed with the density of at least 2000 per square inch.
The first plurality of engagement elements is formed from a subset of the first plurality of loops by disrupting the subset of the first plurality of loops. In some implementations, the subset of the first plurality of loops is physically separated from the plurality of loops. However, the present disclosure is not limited thereto. For instance, in some implementations the subset of the first plurality of loops is a first subset in a plurality of subsets of the first plurality of loops.
The disruption of each loop in the subset of loops forms a corresponding engagement element, which is of the first plurality of engagement elements. In some implementations, the disruption of each loop in the subset of loops forms a set (e.g., a pair) of corresponding engagement elements. In some implementations, the disruption that forms the engagement elements is a process of repeatedly engaging the subset of loops with a sheet of material (e.g., a sheet of carbon, a sheet of glass, a sheet of sand paper). The repeated engagement is conducted in such a way that the subset of loops and the sheet of material engage (e.g., create friction between one another), in a single direction (e.g., the sheet of material repeatedly traverses the subset of loops in a single direction). In some implementations, the one direction is either a linear motion or a rotational motion. This single direction engagement ensures that the mircohooks are formed with a similar orientation, which provides a smooth texture for the wearer of the bra. However, the present disclosure is not limited thereto. For instance, in some implementations the repeated engagement is conducted in such a way that the subset of loops and the sheet of material engage (e.g., create friction between one another), in one or more directions (e.g., the sheet of material repeatedly traverses the subset of loops in a first direction and a second direction).
In various implementations, each engagement element is in the form of a microhook. These microhooks may be formed as an arc, in a J-shape, in a mirrored J-shape, in a partial U-shape (e.g., there is a gap forming an interruption in the U-shape), in a partial V-shape (e.g., there is a gap forming an interruption in the V-shape), or a combination thereof. Moreover, in some implementations, each engagement element is formed in a shape that is approximately similar to a shape of a fishing-hook (e.g., a bait hook, a circle hook, a treble hook).
The mating fastener 1014 is formed from a knitted material (e.g., cotton or wool) that includes a second plurality of loops. In some implementations, the knitted material of the mating fastener 1014 is the knitted material of the touch fastener 1012. However, in various implementations, the knitted material of the mating fastener 1014 is different than the knitted material of the touch fastener 1012. These knitted materials of the touch fastener and the mating fastener include, but are not limited to, cotton, wool, plastics, as other fabrics as described in the present disclosure.
This second plurality of loops serve as the second plurality of engagement elements. (e.g., the second plurality of loops engage the first plurality engagement elements). When the touch fastener 1012 and the matching fastener 1014 engage, individual loops in the second plurality of loops reversibly engage with individual engagement elements (e.g., microhooks) in the first plurality of engagement elements. In some implementations, each fastener is formed in a way that is as described by U.S. Pat. No. 4,884,323 “Quite Touch Fastener Attachment,” which is herein incorporated by reference in its entirety.
In various embodiments, the touch fastener 1012 and the mating fastener 1014 are each magnetized. These magnetized fastener implementations will be described in more detail infra, and particularly with respect to
While the above implementations describe the strap 1004 on one side of the underband 112, or the band 102, the present disclosure is not limited thereto. For instance, in some implementations, there is a corresponding strap 1004 for each gusset 1000 on the underband 112, or the band 102, of the bra 100. In other implementations, there is a corresponding strap 1004 for each underarm portion of the band 102.
In various implementations, and as illustrated in at least
In various embodiments, each touch fastener (146, 156) has a length that is shorter than a length of the corresponding mating fastener (148, 158). As previously described, this difference in length of the respective fastening members allows for the touch fastener (146, 156) to engage the corresponding matching fastener (148, 158) at a variety of positions in a widely adjustable manner. For instance, if the wearer wants a looser fit (e.g., when putting on or pulling off the bra) the touch fasteners (146, 156) may engage the corresponding mating fasteners (148, 158) at a position that is proximate to the corresponding loop straps (144, 154), which provides a maximum length for the respective second straps (e.g., second straps 142, 152). Further, since each wearer of a bra 100 has a different length of torso and a different personal preference for a fit of the bra, the wide range of adjustability of the fasteners allows wearer to adjust the bra for both intense, high impact activities such as sports while also being adjustable for causal, low impact activities such as office work.
In various implementations, and as illustrated in at least
In various implementations, each fastener portion of the shoulder straps (e.g., touch fasteners 146, 156 and mating fasteners 148, 158) is magnetized with a corresponding single neodymium magnet. Similarly, in some implementations each fastener portion of the shoulder straps (e.g., touch fasteners 146 and 156, mating fasteners 148 and 158) includes a plurality of neodymium magnets. In some embodiments, each touch fastener (146, 156) is a single neodymium magnet, while each mating fastener (148, 158) includes a plurality of neodymium magnets (e.g., a magnet that corresponds to a small size length of strap, another magnet that corresponds to a medium size or length of strap, and yet another magnet that corresponds to a large size or length of strap). Moreover, in some implementations, the clasp 202 and its corresponding fixtures (802, 804) are each magnetized with a corresponding single neodymium magnet, or in some implementations a plurality of neodymium magnets. In general, the greater the number of magnets associated with each fastener, the greater range of adjustability of the corresponding straps.
In various implementations, each fastener (e.g., touch fasteners 146 and 156, mating fasteners 148 and 158) is magnetized with a corresponding array of neodymium magnets. This array of neodymium magnets is programed, or arranged, to induce a twist on and twist off releasable attachment effect of the corresponding first strap (140, 150) to the corresponding second strap (142, 152). Moreover, in some implementations the clasp 202 and its corresponding fixtures (802, 804) are each magnetized with a corresponding array of neodymium magnets. For instance, in some implementations each magnet of each fastener is programed with at least a first polarity 1702 and a second polarity 1704, which are opposite polarities (e.g., a positive and a negative polarity). This configuration of programed polarities ensures that corresponding fasteners (e.g., touch fastener 146 and mating fastener 148, touch fastener 156 and mating fastener 158) align when engaged, while also providing a sufficient attractive force between the respective fasteners to prevent the magnets from becoming uncoupled accidentally.
Now that a general structures of various implementations of the bras of the present disclosure have been described, various materials of the bra 100 will now be described in detail.
In various implementations, each tessellated cup 120 is formed by liquid lycra painting. Liquid lycra painting is a process which involves spreading, or receiving, liquid lycra in a mold, and allowing the lycra to solidify. Moreover, in some implementations the cradle 130 is formed by liquid lycra painting. Depending on an implementation of the tessellated cups 120, or the cradle 130, the liquid lycra includes between 40 and 95 percent weight volume (w/v) water and between 5-60 percent w/v polyurethane urea. In some implementations, the liquid lycra includes between 40 and 95 percent weight volume (w/v) water and between 5-50 percent w/v polyurethane urea. In some implementations, the liquid lycra includes between 50 and 90 percent weight volume (w/v) water and between 10-50 percent w/v polyurethane urea.
In various implementations, select components of the bra 100 or formed from, or include, a thermoplastic elastomer (TPE). Moreover, in various implementations, select components of the bra 100 or formed from, or include, a thermoplastic rubber or resin (TPR). Components formed may be formed of TPE or TPR include each tessellated cup 120 and the cradle 130. For instance, in some implementations each tessellated cup 120 is formed from a TPE or TPR. In other implementations, the cradle 130 is formed from a TPE or TPR. Moreover, in some implementations, each tessellated cup 120, the gore 110, and the cradle 130 are formed from a TPE or TPR.
In some implementations, the TPR is a styrenic block copolymer. Styrenic block copolymers have a large volume and are considered to be commercially viable (e.g., cheap to produce and fabricate with). In various implementations, the styrenic block copolymers is a blend of other polymers, a variety of oils, and fillers which provides a multitude of different material properties such as a more rigid styrenic block copolymer or a styrenic block copolymers with a larger Young's modulus. When the styrenic block copolymer cools from a liquid to a solid, the material becomes rigid.
In some implementations, the TPR is a thermoplastic polyolefin elastomer such as ethylene-butene or ethylene-octene. These thermoplastic polyolefin elastomer are utilized for portions of the bra which require a certain degree of flexibility.
In some implementations, the TPR is a thermoplastic vulcanizate. These thermoplastic vulcanizates materials are often relatively soft and have an initial bending modulus that is less than or equal to 800 mega Pascal's (MPa).
In some implementations, the TPR is a thermoplastic polyurethane. Like the thermoplastic vulcanizates, thermoplastic polyurethane materials are often relatively soft and have an initial bending modulus that is less than or equal to 500 mega Pascal's (MPa).
Moreover, in some implementations the TPR is a thermoplastic copolyester. Further, in some implementations the TPR is a thermoplastic polyamide.
In various implementations, select components of the bra 100 are formed from an auxetic material. Auxetic materials are defined as having a negative Poisson's ratio (e.g., v is less than 0), which is imparted on the material through microstructures (e.g., cells and/or pores), or geometric units (e.g., a honeycomb geometric unit or a bow-tie geometric unit) in the material. The negative Poisson's ratio means that when a strain (e.g., a tensile strain) is applied to the material, the material expands and becomes fatter in a direction orthogonal to the direction of the applied strain (e.g., a lateral strain forces the auxetic material to expand longitudinally). For instance, if a breasts, which is surrounded by the auxetic material, moves away from its equilibrium position the auxetic material will expand in a direction opposite to the movement of the breast. This expansion in the direction opposite to the motion provides a dampening effect to the breasts and restricts a range of motion of the breasts. In other words, when a force is applied to the auxetic material it becomes stronger as opposed to weaker. These auxetic materials, which are compressible foams, have improved mechanical properties that includes an improved shear modulus, an increased resistance to deformation such as indentations, as well as an increased fracture toughness.
In some implementations the compressible auxetic polymeric foam is formed by undergoing a compression and heat treatment process of a thermoformable polymeric foam. The compression process includes subjecting a conventional foam specimen to a three-dimensional compression (e.g., triaxially) in a mold. In various implementations, the conventional foam is compressed with a volumetric compression ratio (VCR) of from 1.4 to 4. The volumetric compression ratio is defined as an initial volume of the foam divided by a final volume of the foam. In some implementations, once the foam specimen is adequately compressed in the mold (e.g., compressed to a predetermined VCR and/or for a predetermined period of time), the specimen is removed from the mold and partially relaxed or stretched to remove any internal adhesion of cells. The compressed foam specimen is then subjected to a heat treatment for a predetermined period of time in order to soften the foam. In some implementations, this heat treatment is conducted at a temperature of from 100° C. to 200° C. In some implementations, this heat treatment is conducted at a temperature of from 145° C. to 200° C. In some implementations, this heat treatment is conducted at a temperature of from 155° C. to 180° C. In some implementations, this heat treatment is conducted at a temperature of from 163° C. to 171° C. This softening of the foam relaxes any internal stresses formed therein by the compression process, while also setting a shape of the foam. The exact Poisson's ratio of an auxetic foam is determined by processing conditions including a heating time of the material, a conversion temperature of the material during the forming processes, and the volumetric compression ratio of the material during the compression process. The Poisson's ratio of an auxetic material is also related to a number of pores pre inch (ppi) of the material. For instance, auxetic materials with high ppi's (e.g., 60 ppi) tend to have a Poisson's ratio that is closer to zero, whereas auxetic materials with low ppi's (e.g., 10 ppi) tend to have a Poisson's ratio that is closer to −1.
Examples of a thermoformable polymeric foam that is subjected to a compression and heat treatment process includes a G45 polyurethane foam manufactured by the Wm. T Burnett Company, 2112 Montevideo Road, Jessup, Md. 20794. This G45 foam is treated and sold as an auxetic foam by Auxadyne, 200 NE Commercial Drive, Keystone Heights Fla., 32656.
Auxetic foams formed from parent conventional foams have a Young's modulus that is approximately a quarter to a three-quarters of a Young's modulus of the parent foam. For instance, one conventional foam that is transformed into an auxetic foam will have its Young's modulus reduced by approximately 75%. Whereas another conventional foam that is transformed into another auxetic foam will have its Young's modulus reduced by approximately 25%. Additional information regarding the formation and mechanics of auxetic materials is detailed in Chan et. al., 1997, “Fabrication Methods for Auxetic Foams,” Journal of Materials Science, (32), p 5945, as well as Allen et. al., 2015, “Auxetic Foams for Sport Safety Applications,” Procedia Engineering, (112), p. 104. Each of these references is hereby incorporated by reference in their entirety.
In various implementations, each of the tessellated cups 120 is formed from an auxetic foam. In some implementations, the single inner pad layer 306 is formed from an auxetic foam. In some implementations, the single outer pad layer 1510 is formed from an auxetic foam. These various implementations of the present disclosure may have any of the attributes of auxetic foam previously described supra, as well as any of attributes of auxetic foam that will be described infra.
In some implementations, all or one or more portions of the bra 100 is formed from a suitable material for forming undergarments including auxetic foam, cotton, dacron, elastane, hemp, jute, latex, leather, low melt yarn, lycra, modal, nylon, polyamides, polyester, rayon, spandex, silk, tactel, viscose, wool, yarn, or a combination (e.g., a blend) thereof. For instance, in some implementations a first portion of the bra is formed from a first material (e.g., the underband and/or the straps 150 are formed from nylon) while a second portion of the bra is formed from a second material (e.g., each tessellated cup region 120 is formed from auxetic foam). In some implementations, various portions of the bra 100 includes a first material and, optionally, a blend of a second material. For instance, in some implementations the band 102 of the bra 100 is formed using a first material (e.g., cotton) and one or more portions of the band (e.g., the underarm portions, the straps, the back portion, etc.) includes a blend of the first material and a second material (e.g., a blend of polyester and cotton).
In some implementations, one or more portions of the bra 100 is formed individually and combined with other portions of the bra to form the complete garment. For instance, in some implementations the underband 112 and/or one or more straps 150 of the bra is formed individually and combined with other portions of the bra 100 to form a complete garment (e.g., sewn to the other portions of the bra, molded to the other portions of the bra, etc.). However, the present disclosure is not limited thereto. For instance, in some implementations the bra 100 is formed by a continuous, uninterrupted process (e.g., the bra is formed as a complete garment without needing to couple one or more portions of the bra together). Moreover, in some implementations, the band 102 of the bra 100 is formed by a continuous, uninterrupted process and one or more additional portions of the bra (e.g, the tessellated cups 120) are coupled to respective portions of the band 102 once the band is formed. To this point, in some implementations the bra 100 is formed utilizing a circular knitting machine. The circular knitting machine of the present disclosure includes a single knit machine and a double knit machine. In some implementations, the circular knitting machine is a SM4-TL2 single jersey circular knitting machine, which is provided by Santoni company of Via Carlo Fenzi, 14, 25135 Brescia, Italy. In some implementations, the circular knitting machine is a SM8-TOP2V circular knitting machine, a SM8-EVO4J circular knitting machine, a SM8-TR1 circular knitting machine, a SM-DJ2T circular knitting machine, a SM-DJ2TS circular knitting machine, or a SM-DJ circular knitting machine, each of which provided by the Santoni company. Forming the bra 100 through a continuous, uninterrupted process allows for the garment to be seamless, since each portion of the bra is integrally formed with other portions of the bra (e.g., the cup regions and the underarm portions are seamless formed). A seamless bra 100 improves comfort to a user by reducing a prepotency for chafing and/or discomfort to the user, as well as improving a lifespan of the bra since each seam of the bra may bear or be exposed to a high amount of stress and eventually deteriorate or tear.
Depending on both the implementation of the bra 100 and the component of the bra 100, in some implementations the Poisson's ratio is between −0.05 and −0.75. A more negative ratio (e.g., a ratio of −0.75 is more negative than a ratio of −0.10) yields a material that expands to a greater degree, and is associated with a more forgiving, looser dampening effect. For instance, in some implementations where movement of the breasts is less restrictive the Poisson's ratio of components of the bra 100 may be closer to zero. In other implementations where movement of the breasts is more restrictive the Poisson's ratio of components of the bra 100 may be closer to −1. In some implementations, the negative Poisson's ratio is between −0.05 and −0.25, between −0.05 and −0.5, between −0.05 and −0.95, between −0.25 and −0.5, between −0.25 and −0.75, between −0.40 and −0.65, between −0.30 and −0.85, or between −0.08 and −0.85. In some implementations, the auxetic material has a constant Poisson's ratio over deformation (e.g., the Poisson's ratio is a constant number when the material is exposed to both a small deformation and a large deformation). In some implementations, the auxetic material has a variable Poisson's ratio over deformation (e.g., the Poisson's ratio is variable over an exposure to a small deformation, a large deformation, or a transition there between).
In various implementations, the thermoformable polymeric foam is a polyurethane foam. In various implementations, the thermoformable polymeric foam is a closed-cell foam. Alternatively, in some implementations, the thermoformable polymeric foam is an open-cell foam. Open-cell foams refer to foams that have a majority of its cells “open” or exposed to one another, whereas closed-cell foam has a majority of its cells enclosed by its walls and are not interconnecting. Open cell foams are elastically deformable and soft, whereas closed-cell foams are harder are less deformable as compared to their open-celled counterparts. In some implementations, the open-cell foam is a reticulated open-cell polyurethane. Reticulated open-cell polyurethane foams are defined in part by their high porosity (e.g., pores per inch) and their low density. In some implementations, the reticulated open-cell polyurethane has between 20 and 100 pores in-1 (ppi). In some implementations, the reticulated open-cell polyurethane has between 10 and 100 pores in-1, between 10 and 80 pores in-1, between 10 and 60 pores in-1, between 20 and 60 pores in-1, or between 40 and 60 pores in-1. Moreover, in some implementations, the reticulated open-cell polyurethane has a density of 20-35 kg/m3, a density of 26-32 kg/m3, a density of 26-29 kg/m3, or a density of 15-50 kg/m3.
In some implementations, the auxetic foam is a 60 ppi closed-cell polyester urethane foam with a density of 37.9±2.1 kg/m3. In some implementations, the auxetic foam is a 60 ppi reticulated polyester urethane foam with a density of 33.7±1.3 kg/m3.
In some implementations, the auxetic foam is a 10 ppi open-cell polyether urethane foam with a density of 24.1±3.1 kg/m3. In some implementations, the auxetic foam is a 30 ppi open-cell polyether urethane foam with a density of 24.5±2.7 kg/m3. In some implementations, the auxetic foam is a 60 ppi open-cell polyether urethane foam with a density of 21.7±1.9 kg/m3.
