FIELD
The present disclosure relates generally to an adjustment element for an article of apparel.
BACKGROUND
This section provides background information related to the present disclosure which is not necessarily prior art.
Articles of apparel such as garments and headwear and articles of footwear such as shoes and boots, typically include a receptacle for receiving a body part of a wearer. For example, an article of footwear may include an upper and a sole structure that cooperate to form a receptacle for receiving a foot of a wearer. Likewise, garments and headwear may include one or more pieces of material formed into a receptacle for receiving a torso or head of a wearer.
Articles of apparel or footwear are typically adjustable and/or are formed from a relatively flexible material to allow the article of apparel or footwear to accommodate various sizes of wearers, or to provide different fits on a single wearer. While conventional articles of apparel and articles of footwear are adjustable, such articles do not typically allow a wearer to conform the shape of the article to a body part of the wearer. For example, while clasps and elastic bands adequately secure an article of apparel to a wearer by contracting or constricting a portion of a garment around the wearer's upper body, they do not cause the garment to conform to the user's upper body. Accordingly, an optimum fit of the article of apparel around the upper body is difficult to achieve.

DETAILED DESCRIPTION
Example configurations will now be described more fully with reference to the accompanying drawings. Example configurations are provided so that this disclosure will be thorough, and will fully convey the scope of the disclosure to those of ordinary skill in the art. Specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of configurations of the present disclosure. It will be apparent to those of ordinary skill in the art that specific details need not be employed, that example configurations may be embodied in many different forms, and that the specific details and the example configurations should not be construed to limit the scope of the disclosure.
The terminology used herein is for the purpose of describing particular exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of features, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and/or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. Additional or alternative steps may be employed.
When an element or layer is referred to as being “on,” “engaged to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly on, engaged, connected, attached, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
As used herein, the term “approximately” means within a range of plus or minus 5 percent of an indicated value or range, optionally within a range of plus or minus 10 percent of an indicated value or range.
The terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections. These elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first,” “second,” and other numerical terms do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example configurations.
In one configuration, an article of apparel includes a bladder that includes an interior void, a compressible component disposed within the interior void and including a first zone, the first zone operable between a contracted state and a relaxed state, and a port fluidly coupled to the bladder and operable to selectively permit fluid communication with the interior void.
The article of apparel may include one or more of the following optional features. For example, the compressible component may include a first cup and the first zone may be spaced apart from the first cup. Additionally or alternatively, the first zone may extend over at least a portion of the first cup. In one configuration, the first zone may include a first plurality of reliefs having a first shape. The compressible component may include a second zone disposed adjacent to the first zone and may include a second plurality of reliefs. The reliefs of the second plurality of reliefs may include the same shape as reliefs of the first plurality of reliefs. The reliefs of the second plurality of reliefs may be oriented in a transverse direction relative to the reliefs of the first plurality of reliefs.
In one configuration, the article of apparel may include a lining operable to surround a torso of a wearer and a second cup spaced apart from the first cup, the first cup and the second cup may extend to a respective apex in a direction away from the lining. The compressible component may extend at least partially over the first cup and the second cup. Optionally, the port may be disposed between the first cup and the second cup, the first cup and the second cup being in fluid communication.
In another configuration, an article of apparel includes a bladder including an interior void, a compressible component disposed within the interior void and including a first cup extending to a first apex and a second cup extending to a second apex, the compressible component including a first zone operable between a contracted state and a relaxed state, and a port fluidly coupled to the bladder and operable to move the first zone between the contracted state and the relaxed state by selectively permitting fluid communication with the interior void.
The article of apparel may include one or more of the following optional features. For example, the first zone may extend over the first apex. Additionally or alternatively, the first zone may extend over the second apex. The first zone may include a first plurality of reliefs having a first shape. Optionally, the compressible component may include a second zone disposed adjacent to the first zone and including a second plurality of reliefs. Reliefs of the second plurality of reliefs may include the same shape as the reliefs of the first plurality of reliefs. The first zone may extend at least partially over the first apex and the second apex. The port may be disposed between the first cup and the second cup, the first cup and the second cup being in fluid communication.
Referring to FIGS. 1-3, an upper-torso article of apparel 10 is illustrated and includes any garment configured to cover an upper-torso of a wearer. The illustrated upper-torso article of apparel 10 includes a bra 10, however the bra 10 may include other types of garments for a male or female, including a strapless bra, a camisole, a base-layer shirt, a singlet, swimwear, sports bra, or other garments with built-in support. FIG. 2 depicts another example of a configuration of a bra 10a. In view of the substantial similarity in structure and function of the components associated with the bra 10a with respect to the bra 10, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified. The bras 10, 10a are contemplated as being a support garment that may include a first breast covering portion and a second breast covering portion. The first and second breast coverings may optionally include one or more zones, as described in more detail below with respect to FIGS. 8-14.
Referring to FIGS. 1 and 2, the bras 10, 10a each may include an anterior side 12 associated with the front of the body of a wearer when the bras 10, 10a are in use, and a posterior side 14 associated with the back of the body of a wearer when the bras 10, 10a are in use. The bras 10, 10a may further include an upper end 16 configured to receive the shoulders of the wearer, and a lower end 18 configured to receive the ribcage of a wearer. A longitudinal axis A10 of the bras 10, 10a extends along a height of the bras 10, 10a from the upper end 16 to the lower end 18 perpendicular to a ground surface, and generally divides the bras 10, 10a into a right side 20 and a left side 22. Accordingly, the right side 20 and the left side 22 respectively correspond with opposite sides of the bras 10, 10a and extend from the upper end 16 to the lower end 18. As used herein, a longitudinal direction refers to the direction extending from the upper end 16 to the lower end 18, while a sagittal direction refers to the direction transverse to the longitudinal direction and extending from the anterior side 12 to the posterior side 14. A frontal axis or direction refers to the direction extending from the right side 20 to the left side 22.
The bras 10, 10a may be divided into one or more regions. The regions may include a shoulder region 24, a chest region 26, and a ribcage region 28. The shoulder region 24 is associated with the clavicle and scapula bones of a shoulder. The chest region 26 may correspond with the true ribs and breast tissue area of an upper-torso, and the ribcage region 28 may correspond with the false and floating ribs of an upper-torso.
The bras 10, 10a further include an interior cavity 30, a neck-receiving opening 32, a torso-receiving opening 34, a right arm-receiving opening 36, and a left arm-receiving opening 38. As shown in FIGS. 1 and 2, the neck-receiving opening 32 is formed on the upper end 16 of the bras 10, 10a and the torso-receiving opening 34 is formed on the lower end 18 of the bras 10, 10a. The neck-receiving opening 32 is further formed by a neckline 40 extending along a perimeter of the neck-receiving opening 32. Similarly, the torso-receiving opening 34 is further formed by a band 42 extending along a perimeter of the torso-receiving opening 34. While the band 42 is illustrated as including a clasp (FIG. 3), it may alternatively be circumferentially connected at the lower end 18 by an elastic band.
The bras 10, 10a, and components thereof, may be further described as including various subcomponents or regions. For example, the bras 10, 10a include a front panel 44 having a right panel 46 disposed at the anterior side 12 and extending from the shoulder and chest regions 24, 26 to the ribcage region 28 and from the right side 20 to a center bridge 48 disposed between the right side 20 and the left side 22. As best shown in FIGS. 1 and 2, the front panel 44 further includes a left panel 50 disposed at the anterior side 12 and extending from the chest region 26 to the ribcage region 28 and from the left side 22 toward the center bridge 48.
The right panel 46 and the left panel each further include a central cup region 52 associated with the bust line of the wearer, a perimeter cup region 54 disposed around the perimeter of the right and left panels 46, 50 and a transition region 56 disposed between the central cup region 52 and the perimeter cup region 54. A first cup 58 and a second cup 60 of the bras 10, 10a are disposed within the central cup region 52 and extend to a respective apex. Each of the first cup 58 and the second cup 60 includes a generally convex shape to accommodate and provide support for the chest of the wearer while in-use. The central cup region 52 includes a generally convex shape to accommodate and provide support for the chest of the wearer while in-use.
The transition region 56 of the front panel 44 may include a bottom region 56a disposed around a bottom portion of the central cup region 52 and proximate to the lower end 18 of the bras 10, 10a and an upper region 56b disposed around an upper portion of the central cup region 52 and neckline 40 of the bras 10, 10a. More specifically, the upper region 56b refers to the portion of each panel 46, 50 that extends upwardly from a respective one of the cups 58, 60 and corresponds to an upper bust area of the wearer, while the bottom region 56a refers to the portion of each panel 46, 50 that extends downwardly from a respective one of the cups 58, 60 and corresponds to the under bust of the wearer. The bra 10 illustrated in FIG. 1 further includes an adjustment element 102 and a port 200 operable to move adjustment element 102 between a relaxed state and a constricted state. The bra 10a illustrated in FIG. 2 also includes the port 200 and another example of an adjustment element 102a, described below, that cooperate with the perimeter cup and transition regions 54, 56 to expand and contract the bra 10a, while the central cup region 52 may remain generally passive. Stated differently, the perimeter cup and transition regions 54, 56 of the bra 10a may compress about the wearer to provide structural support for the upper torso of the wearer, while the passive condition of the central cup region 52 minimizes compressive engagement of sensitive portions of the upper torso of the wearer.
The bras 10, 10a may further include a back panel 62 and a pair of straps 64, extending between the anterior side 12 and the posterior side 14 of the bras 10, 10a. The back panel 62 wraps across the posterior side 14 from the right side 20 to the left side 22, and includes a height that tapers in a direction from the straps 64 to the respective right side 20 and left side 22. The pair of straps 64 extend from the back panel 62 and generally form a “T” or “Y” shape and, further, extend over the shoulders of the wearer and connect to the right panel 46 and the left panel 50 at the anterior side 12 of the bras 10, 10a.
With reference to FIG. 3, the bra 10 may include a lining 100 opposing a wearer during use and at least partially forming the interior cavity 30 (FIG. 1). Although described with respect to the bra 10, it is contemplated that the bra 10a may also include the lining 100 as described herein. It is contemplated that the lining 100 may be incorporated as part of the front panel 44 and/or the back panel 62 (FIG. 1). Additionally or alternatively, the lining 100 may also be incorporated in other portions of the bra 10 including, but not limited to, the straps 64, the center bridge 48, and/or the band 42. The lining 100 may be formed from one or more materials that are coupled together. For example, the materials of the lining 100 may be stitched or adhesively bonded together. Suitable materials of the lining 100 may include, but are not limited to stretch woven fabric, knit fabric, non-woven fabric and/or a composite construction. Moreover, the lining 100 may possess moisture-management characteristics such as wicking, breathability, fast-drying times, and other similar characteristics. The lining 100 may include a combination of one or more substantially inelastic or non-stretchable materials and one or more substantially elastic or stretchable materials disposed in different regions of the bra 10 to facilitate movement of the bra 10 between a tightened state and a loosened state. The one or more elastic materials may include any combination of one or more elastic fabrics such as, without limitation, spandex, elastane, rubber or neoprene. The one or more inelastic materials may include any combination of one or more of thermoplastic polyurethanes, nylon, leather, vinyl, or another material/fabric that does not impart properties of elasticity. Accordingly, the lining 100 may stretch, thereby allowing the bra 10 to stretch around the upper-torso to be easily donned and doffed.
Referring to FIGS. 1-4B, the front panel 44 of the bra 10 may further include the adjustment element 102 attached to the lining 100. In some implementations, the bra 10 may optionally include an additional outer layer or shell 100a attached to the lining 100 to enclose the adjustment element 102 between the lining 100 and the shell 100a. The adjustment element 102 includes a bladder 104 forming an interior void 106 having a compressible component or infill 108 disposed therein. It is generally contemplated that the bladder is configured to form a three-dimensional shape. The three-dimensional shape may be based on a body part shape and/or may be a bra cup shape. In one example, the three-dimensional shape is based on a bra shape including a first breast covering portion and a second breast covering portion. Further, the three-dimensional shape includes a middle connecting portion between the first breast covering portion and the second breast covering portion. In one example, the compressible component includes a plurality of reliefs in each of the first breast covering portion and the second breast covering portion.
In another example, the compressible component includes the plurality of reliefs in each of the first breast covering portion and the second breast covering portion, but the compressible component does not include the plurality of apertures in the middle connecting portion.
The bladder 104 is operable to transition between a fully relaxed state, a fully contracted or constricted state, and one or more intermediate states. In one example, the bladder 104 is configured to have a first three-dimensional shape and is configured to transition from the first three-dimensional shape to a second three-dimensional shape or vice-versa, responsive to a change in an amount of vacuum in the interior space. In one example, the first three-dimensional shape and the second three-dimensional shape may be the same shape but have different overall sizes (e.g., transition to smaller size from a larger size responsive to increase in vacuum). As illustrated in FIG. 1A, it is also contemplated that the compressible component 108 may taper toward the rear panel 62 to form a graded low-profile from the central cup region 52 toward the rear panel 62 to minimize the profile of the compressible component 108 relative to the rear panel 62.
The bladder 104 may include a first zone and a second zone, such that the first zone is operable to transition between the fully relaxed state, the fully expanded state, and one or more of the intermediate states while the second zone may substantially remain in the same state. The zones of the bladder 104 are described in more detail below with respect to FIGS. 8-14 and it is contemplated that each zone is configured to provide a degree of containment to a wearer. The degree of containment may be different across different zones of the bladder. In addition, the first zone may be configured for selective fluid communication between an interior space of the first zone and the atmosphere, as described below with respect to FIGS. 15B and 15C.
FIGS. 4A and 4B illustrate a cross-sectional view of an example of the adjustment element 102 transitioning from the relaxed state (FIG. 4A) to the constricted state (FIG. 4B) taken along Line 4-4 of FIG. 1. As shown in FIG. 4A, the compressible component 108 includes a first surface 110a on a first side of the compressible component 108 and a second surface 110b on an opposite second side of the compressible component 108. A distance from the first surface 110a to the second surface 110b has a thickness T108 of the compressible component 108. For example, the thickness T108 of the compressible component 108 may be approximately 6 millimeters. It is also contemplated that the compressible component 108 may have a thickness ranging from approximately 2 millimeters to approximately 10 millimeters. Alternatively, the thickness T108 may be equal to or less than 2 millimeters or greater than or equal to 10 millimeters. Additionally or alternatively, the compressible component 108 may have a varied thickness T108 across the compressible component 108. Finally, while the compressible component 108 is described as having a thickness in the foregoing ranges, the thickness of the compressible component 108 may be dependent on the material used. As discussed in greater detail below, the compressible component 108 is operable to transition the adjustment element 102 and the bra 10 between a relaxed state (FIG. 17A) and a constricted state (FIG. 17B), as described in more detail below.
In the illustrated examples, the adjustment element 102 includes an inner barrier layer 112a attached to a first surface of the lining 100, and an outer barrier layer 112b forming at least a portion of an exterior surface of the bra 10. Stated differently, the bladder 104 may include the outer barrier layer 112b, the inner barrier layer 112a, and the bladder space or interior void 106 therebetween. The outer barrier layer 112b, the inner barrier layer 112a, and the compressible component 108 are coupled along a perimeter of the bladder 104, as described in more detail below. Interior surfaces of the barrier layers 112a, 112b face each other and are joined to each other to form a peripheral seam 114 that surrounds the interior void 106 to form a chamber 116 of the bladder 104. The second surface 110b and the outer barrier layer 112b may be separate from each other except at the perimeter, and the first surface 110a and the inner barrier layer 112a may be separate from each other except at the perimeter.
As used herein, the term “barrier layer” (e.g., barrier layers 112a, 112b) encompasses both monolayer and multilayer films. In some configurations, one or both of barrier layers 112a, 112b are produced (e.g., thermoformed or blow molded) from a monolayer film (a single layer). In other configurations, one or both of the barrier layers 112a, 112b are produced (e.g., thermoformed or blow molded) from a multilayer film (multiple sublayers). In either aspect, each layer or sublayer can have a film thickness ranging from approximately 0.2 micrometers to approximately 1 millimeter. In further configurations, the film thickness for each layer or sublayer can range from approximately 0.5 micrometers to approximately 500 micrometers. In yet further configurations, the film thickness for each layer or sublayer can range from approximately 1 micrometer to approximately 100 micrometers.
One or both of the barrier layers 112a, 112b can independently be transparent, translucent, and/or opaque. As used herein, the term “transparent” for a barrier layer means that light passes through the barrier layer in substantially straight lines and a viewer can see through the barrier layer. In comparison, for an opaque barrier layer, light does not pass through the barrier layer and one cannot see clearly through the barrier layer at all. A translucent barrier layer falls between a transparent barrier layer and an opaque barrier layer, in that light passes through a translucent layer but some of the light is scattered so that a viewer cannot see clearly through the layer.
The barrier layers 112a, 112b can each be produced from an elastomeric material that includes one or more thermoplastic polymers and/or one or more cross-linkable polymers. In an aspect, the elastomeric material can include one or more thermoplastic elastomeric materials, such as one or more thermoplastic polyurethane (TPU) copolymers, one or more ethylene-vinyl alcohol (EVOH) copolymers, and the like. In one example, one or both of the barrier layers 112a, 112b may include a film disposed along an outer surface of the barrier layer(s) 112a, 112b or that forms the barrier layer(s) 112a, 112b. The film may optionally be configured to tactically correspond to a textile that has the look and/or feel of a textile in terms of appearance and/or stretchability but is able to contain a fluid with the bladder 104. For example, the film may be formed from a TPU textile composite. The film may assist in fluid flow along the barrier layer(s) 112a, 112b while cooperating to retain fluid within the bra 10.
As used herein, “polyurethane” refers to a copolymer (including oligomers) that contains a urethane group (—N(C═O)O—). These polyurethanes can contain additional groups such as ester, ether, urea, allophanate, biuret, carbodiimide, oxazolidinyl, isocynaurate, uretdione, carbonate, and the like, in addition to urethane groups. In an aspect, one or more of the polyurethanes can be produced by polymerizing one or more isocyanates with one or more polyols to produce copolymer chains having (—N(C═O)O—) linkages.
Examples of suitable isocyanates for producing the polyurethane copolymer chains include diisocyanates, such as aromatic diisocyanates, aliphatic diisocyanates, and combinations thereof. Examples of suitable aromatic diisocyanates include toluene diisocyanate (TDI), TDI adducts with trimethyloylpropane (TMP), methylene diphenyl diisocyanate (MDI), xylene diisocyanate (XDI), tetramethylxylylene diisocyanate (TMXDI), hydrogenated xylene diisocyanate (HXDI), naphthalene 1,5-diisocyanate (NDI), 1,5-tetrahydronaphthalene diisocyanate, para-phenylene diisocyanate (PPDI), 3,3′-dimethyldiphenyl-4, 4′-diisocyanate (DDDI), 4,4′-dibenzyl diisocyanate (DBDI), 4-chloro-1,3-phenylene diisocyanate, and combinations thereof. In some configurations, the copolymer chains are substantially free of aromatic groups.
In particular aspects, the polyurethane polymer chains are produced from diisocynates including HMDI, TDI, MDI, H12 aliphatics, and combinations thereof. In an aspect, the thermoplastic TPU can include polyester-based TPU, polyether-based TPU, polycaprolactone-based TPU, polycarbonate-based TPU, polysiloxane-based TPU, or combinations thereof.
In another aspect, the polymeric layer can be formed of one or more of the following: EVOH copolymers, poly(vinyl chloride), polyvinylidene polymers and copolymers (e.g., polyvinylidene chloride), polyamides (e.g., amorphous polyamides), amide-based copolymers, acrylonitrile polymers (e.g., acrylonitrile-methyl acrylate copolymers), polyethylene terephthalate, polyether imides, polyacrylic imides, and other polymeric materials known to have relatively low gas transmission rates. Blends of these materials as well as with the TPU copolymers described herein and optionally including combinations of polyimides and crystalline polymers, are also suitable.
The barrier layers 112a, 112b may include two or more sublayers (multilayer film), such that two sheets of the multilayer film may be placed on top of each other and welded together along selected points using conventional heat sealing techniques of radiofrequency (RF) welding techniques to form an interior compartment. In configurations where the barrier layers 112a, 112b include two or more sublayers, examples of suitable multilayer films include microlayer films, for example a microlayer polymeric composite including at least approximately 10 layers and may range between at least approximately 10 layers to at least approximately 50 layers and/or microlayer elastomer membranes including at least approximately 10 to approximately 1000 layers. The average thickness of each individual layer may be as low as a few nanometers to as high as several mils (approximately 100 microns) thick. In further configurations, barrier layers 112a, 112b may each independently include alternating sublayers of one or more TPU copolymer materials and one or more EVOH copolymer materials, where the total number of sublayers in each of the barrier layers 112a, 112b includes at least four (4) sublayers, at least ten (10) sublayers, at least twenty (20) sublayers, at least forty (40) sublayers, and/or at least sixty (60) sublayers.
The chamber 116 can be produced from the barrier layers 112a, 112b using any suitable technique, such as thermoforming (e.g. vacuum thermoforming), blow molding, extrusion, injection molding, vacuum molding, rotary molding, transfer molding, pressure forming, heat sealing, casting, low-pressure casting, spin casting, reaction injection molding, radio frequency (RF) welding, and the like. In an aspect, the barrier layers 112a, 112b can be produced by co-extrusion followed by vacuum thermoforming to produce the chamber 116. The chamber 116 desirably has a low gas transmission rate.
In some implementations, the inner barrier layer 112a and the outer barrier layer 112b cooperate to form a geometry (e.g., thicknesses, width, and lengths) of the chamber 116. The peripheral seam 114 may extend around the chamber 116 to seal the chamber 116 and allow a vacuum to be applied to the chamber 116. Thus, the chamber 116 is associated with an area of the bladder 104 where interior surfaces of the upper and lower barrier layers 112a, 112b are not joined together and, thus, are separated from one another. The compressible component 108 is received within the chamber 116 in areas where the barrier layers 112a, 112b are not joined together. Finally, while the peripheral seam 114 is described and shown as sealing the chamber 116, the peripheral seam 114 may also be used to attach the lining 100 to the bladder 104. Namely, a material forming the lining 100 may be fused to a material forming the barrier layer(s) 112a, 112b when the peripheral seam 114 is formed by causing a material of one or more of the barrier layers 112a, 112b to flow and, thus, bond to a material of the lining 100.
In some examples, the barrier layers 112a, 112b may include the same materials to provide the chamber 116 with a homogenous barrier construction, such that both sides of the adjustment element 102 will contract and relax at the same rate when pressure within the chamber 116 is adjusted. Alternatively, a first one of the barrier layers 112a, 112b may be at least partially constructed of a different barrier material and/or configuration than the other one of the barrier layers 112a, 112b to selectively impart a contour as the adjustment elements 102, 102a transition between the relaxed state and the contracted state. For example, one of the barrier layers 112a, 112b may be at least partially formed with a different modulus of elasticity and/or stiffness than the other barrier layer 112a, 112b, such that when the adjustment elements 102, 102a transition from the relaxed state to the constricted state, the first one of the barrier layers 112a, 112b contracts at a different rate than the other barrier layer 112a, 112b to cause the adjustment element to curl.
Continuing with reference to FIGS. 4A and 4B, the compressible component 108 forms a transformable structure that selectively moves the bra 10 between the relaxed state and the constricted state. The first surface 110a of the compressible component 108 faces the inner barrier layer 112a and the second surface 110b faces the outer barrier layer 112b. In this example, the compressible component 108 includes a collapsible lattice structure 118 having a plurality of apertures or cells or reliefs 120, described in more detail below, formed through the thickness T108 (i.e., direction from the inner barrier layer 112a to the outer barrier layer 112b) of the compressible component 108. The plurality of reliefs 120 may have a first geometric shape and are configured to form the lattice structure 118. The compressible component is disposed within the bladder space or interior void 106 and includes the plurality of reliefs 120. It is contemplated that the lattice structure 118 may be formed from an EVA material and may be cut flat to optionally form an outline of the compressible component 108 and/or the reliefs 120. In one example, the compressible component 108 may be laser cut to form the reliefs 120, such that the heat from the laser may provide a sealing skin along the reliefs 120 to advantageously improve the structural integrity of the compressible component 108. The compressible component 108 may be subsequently thermoformed into a desired three-dimensional shape. In one example, after thermoforming, the compressible component 108 may be disposed within the interior void 106 of the adjustment element 102. In another example, the compressible component may be positioned between the barrier layers 112a, 112b, and the compressible component and the barrier layers may be coupled (e.g., welded at at least the periphery) to form the adjustable element 102. In yet another example, the compressible component 108, as well as the inner and the outer barrier layers 112a and 112b may be each thermoformed into the desired three-dimensional shape (e.g., bra cup shape) and welded all around the perimeter to form the adjustable element 102. In some examples, when it is desired to block application of vacuum to one or more restricted zones, the one or more zones of the compressible component may be bonded to both the barrier layers at the restricted zones where vacuum is not desired. For example, a material that may bond with both the compressible component and the barrier layers may be positioned at the restricted zones where vacuum is not desired, and thermally bonded to prevent air flow out of these zones. Alternatively to thermoforming, the compressible component 108 may be injection molded to obtain the desired three-dimensional shape prior to being positioned within the interior void 106, or being positioned between the barrier layers 112a, 112b and coupled at the periphery to the barrier layers 112a, 112b. Generally, when a pressure within the chamber 116 is reduced, the lattice structure 118 collapses within the chamber 116 to transition the adjustment element 102 from the relaxed or expanded state to the constricted state. For example, at a first amount of vacuum, the bladder 104 is in the first three-dimensional shape and an outer surface 110b is substantially smooth when the bladder 104 is in the first three-dimensional shape, and at a second amount of vacuum, the second amount of vacuum being greater than the first amount, the outer surface 110b has a plurality of ridges and/or depressions based on the lattice structure 118 when the bladder 104 is in the second three-dimensional shape. In one example, the first amount of vacuum is zero inHg (e.g., no vacuum). In another example, the vacuum may range between approximately 0 inHg and approximately 23 inHg.
It is contemplated that when the bra 10 is worn by the wearer, the outer surface 110b is substantially smooth with a generally uniform appearance when the bladder 104 is free from the vacuum compared to when the vacuum is drawn in the bladder 104 to form the plurality of ridges. Under vacuum, the bra 10 may appear to have a series of depressions that correspond with the compressed state of the lattice structure 118, which is in response to the altered configuration of the reliefs 120. In one example, the reliefs 120 may be arranged along horizontal and/or vertical axes of the support garment or bra 10. It is also contemplated that the reliefs may be arranged radially in a direction from a center of the first and/or second breast covering portion towards a periphery of the first and/or second breast covering portion.
Referring again to FIGS. 4A and 4B, the adjustment element 102 may also include a plurality of channels 122 etched or otherwise disposed along the lattice structure 118 to promote fluid movement within the chamber 116. Further, the plurality of channels 122 provide fluid movement into and out of the chamber 116. In one example, the channels 122 may extend a partial width of the relief 120, such that each channel 122 may be less than a width and/or thickness of the respective relief 120. Stated differently, a depth of each channel 122 is less than a thickness of the reliefs 120. Further, a width of each channel 122 may be less than or equal to a width of a respective wall of the relief 120 on which the channel 122 is formed. By way of example, not limitation, the channels 122 may be configured as wells having a dimension in a range between 2 millimeters (mm) by 2 mm to 0.25 mm by 0.25 mm. In one example, each channel 122 may be approximately 0.5 mm by approximately 0.5 mm. In some examples, the channel 122 dimensions may be greater or lesser based on a type and/or thickness of compressible material used. Further, in some examples, a channel depth may be greater than a channel width or vice-versa.
The channels 122 may be positioned along the first and/or second surface 110a, 110b and include a fluid path within the chamber 116. For example, the channels 122 may extend between the reliefs 120 to fluidly connect each of the reliefs 120. It is also contemplated that the channels 122 may extend around a periphery of the compressible component 108 to provide peripheral fluid paths and promote airflow and circulation within the chamber 116. In one example, the channels 122 may be formed using a laser etching process prior to thermoforming the compressible component 108. The laser etching process may form the channels 122 into the compressible component 108 and, as a result, promote fluid flow within the bra 10 by increasing fluid circulation between the reliefs 120. For example, as mentioned below, the compressible component 108 may include an elastomeric material, such as an ethylene-vinyl acetate foam (EVA), such that the channels 122 provide fluid flow through an otherwise non-porous material. The laser etching process for forming the channels 122 may be performed at a lower power than the laser cutting process for forming the reliefs 120.
FIGS. 5A and 5B illustrate a cross-sectional view of an example of the adjustment element 102a transitioning from the relaxed state (FIG. 5A) to the constricted state (FIG. 5B) taken along Line 5-5 of FIG. 2. In view of the substantial similarity in structure and function of the components associated with the adjustment element 102, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified.
The adjustment element 102a may be integrated in the front panel 44 of the bra 10a (FIG. 2) and includes a bladder 104 forming a bladder space or interior void 106 having a compressible component or infill 108a disposed therein. As shown in FIG. 5A, the compressible component 108a includes a first surface 110a on a first side of the compressible component 108a and a second surface 110b on an opposite second side of the compressible component 108a. A distance from the first surface 110a to the second surface 110b has a thickness T108a of the compressible component 108a. For example, the thickness Tim of the compressible component 108a may be approximately 6 millimeters. It is also contemplated that the compressible component 108a may have a thickness ranging from approximately 2 millimeters to approximately 10 millimeters. Alternatively, the thickness Tim may be equal to or less than 2 millimeters or greater than or equal to 10 millimeters. Additionally or alternatively, the compressible component 108a may have a varied thickness T108a across the compressible component 108a. Finally, while the compressible component 108a is described as having a thickness in the foregoing ranges, the thickness of the compressible component 108a may be dependent on the material used. As discussed in greater detail below, the compressible component 108a selectively transitions the adjustment element 102a and the bra 10a between a relaxed state (FIG. 18A) and a constricted state (FIG. 18B) to adjust a fit of the bra 10a around a torso of a wearer.
In the illustrated examples, the adjustment element 102a includes an inner barrier layer 112a attached to a first surface of the lining 100, and an outer barrier layer 112b forming at least a portion of an exterior surface of the bra 10a. Stated differently, the bladder 104 may include the outer barrier layer 112b, the inner barrier layer 112a, and the bladder space or interior void 106 therebetween. Interior surfaces of the barrier layers 112a, 112b face each other and are joined to each other to form a peripheral seam 114 that surrounds the interior void 106 to form a chamber 116 of the bladder 104.
In this example, the compressible component 108a includes a collapsible lattice structure 118a having a plurality of apertures or reliefs 120a formed through the thickness T108a (i.e., direction from the inner barrier layer 112a to the outer barrier layer 112b) of the compressible component 108a. The compressible component 108a may be cut flat (e.g., laser cut) to form an outline of the compressible component 108a and/or the reliefs 120a. The compressible component illustrated in FIGS. 5A and 5B is free from the channels 122, such that the lattice structure 118a of the compressible component 108a may be free from peripheral fluid paths. In this alternate configuration, it is contemplated that the compressible component 108a may be formed from a porous material that assists in fluid flow and circulation within the chamber 116. As the adjustment element 102a collapses (FIG. 5B), the outer barrier layer 112b may be drawn into the reliefs 120a towards the inner barrier layer 112a. Optionally, the outer barrier layer 112b may contact the inner barrier layer 112a such that friction between the inner barrier layer 112a and the outer barrier layer 112b causes the lining 100 of the front panel 44 to increase in stiffness when the adjustment element 102a is in the constricted state.
As the bra 10 is evacuated, the barrier layers 112a, 112b are drawn against the compressible component 108 and are generally constricted as a result of increase in vacuum. For example, as illustrated in FIGS. 4B and 5B, the barrier layers 112a, 112b may be at least partially depressed within or otherwise at least partially disposed within the reliefs 120, 120a defined by the lattice structures 118, 118a as the vacuum is drawn and the compressible components 108, 108a are translated into the contracted state. If the compressible component 108, 108 includes channels 122, the overall size and depth of the channels 122 is relatively small when compared to the size of the reliefs 120, 120a. As such, the barrier layers 112a, 112b may not extend into the channels 122 when a vacuum is drawn.
As described herein, the adjustment elements 102, 102a include the compressible components 108, 108a, respectively, which are formed in part by the lattice structures 118, 118a. The lattice structures 118, 118a include the reliefs 120, 120a that are configured to collapse or otherwise constrict under the vacuum. Stated differently, the lattice structures 118, 118a of the compressible components 108, 108a change as the at least partial vacuum is drawn, such that the reliefs 120, 120a may reduce in overall size to form a more rigid structure.
As the vacuum is drawn, fluid (e.g., air) is removed from the bladder 104 and the reliefs 120, 120a of the lattice structures 118, 118a are compressed along the x-axis while simultaneously expanding along the y-axis. With respect to the adjustment elements 102, 102a, the vacuum is drawn within the bladder 104, which results in the constriction of the lattice structures 118, 118a as a result of the vertical expansion and horizontal contraction of the reliefs 120, 120a. As a result of the constriction of the lattice structures 118, 118a, it is contemplated that the adjustment elements 102, 102a as a whole, including the barrier layers 112a, 112b, may be reduce in height along a z-axis as a result of the vacuum defined within the bladder 104. Stated differently, the three dimensional adjustment of the adjustment elements 102, 102a is achieved as a result of the vacuum drawn within the bladder 104 to alter the configuration of the reliefs 120, 120a. The lattice structures 118, 118a may thus be constricted to generally restrict a chest of the wearer to minimize movement and provide advantageous compression. In one example, a volume of the adjustable element decreases responsive to increase in vacuum within the bladder. As a non-limiting example, a volume of a bra cup is decreased responsive to application of vacuum. For example, a larger bra cup size may transition to a smaller bra cup size responsive to application of vacuum. Further, a wearer may adjust an amount of vacuum based on a desired compression or tightness. As a result, the amount of compression or tightness of the bra 10, 10a relative to the wearer is greater as the vacuum is applied to the adjustment element 102, 102a compared to when the vacuum is released.
The lattice structures 118, 118a also provide a three-dimensional structure that assists in the compressive movement as the compressible components 108, 108a translate from the relaxed state to the constricted state. The multi-directional compression maximizes the amount of constriction and, thus, support for the wearer. Stated differently, the lattice structures 118, 118a of the compressible components 108, 108a advantageously translate along each of an x- and y-axis to provide a maximum desired compressive force for the wearer, which assists in further supporting the wearer when the compressible components 108, 108a are in the constricted state. As illustrated in FIGS. 4A-5B, while the overall size of the compressible components 108, 108a and lattice structures 118, 118a are compressed and reduced, it is contemplated that the individual reliefs 120, 120a when configured as a diamond shaped relief, may simultaneously shrink or otherwise be compressed along the x-axis (that is, short diagonal) and elongated along the y-axis (that is, long diagonal).
Referring again to FIGS. 4A and 4B, the compressible component 108 may be attached along a perimeter to the corresponding barrier layer 112a, 112b when the adjustment element 102 is assembled to form the peripheral seam 114 of the adjustment element 102. Stated differently, the surfaces 110a, 110b of the compressible component 108 may be attached to the barrier layer(s) 112a, 112b along the peripheral seam 114 to form the chamber 116 of the bladder 104, as mentioned above, while being otherwise generally free from attachment. As illustrated in FIG. 4B, it is contemplated that the surfaces 110a, 110b may be drawn toward the barrier layers 112a, 112b when the adjustment element 102 is compressed under vacuum. While the surfaces 110a, 110b may be proximate or otherwise engaged with the barrier layers 112a, 112b when the vacuum is drawn, the surfaces 110a, 110b may remain otherwise unattached relative to the barrier layers 112a, 112b at areas other than the peripheral seam 114. It is also contemplated that the surfaces 110a, 110b may be spot welded or bonded with the barrier layers 112a, 112b to form portions of the compressible component 108 that may be static or otherwise free from constriction as a result of the vacuum applied, as described with respect to FIGS. 7-14 below. Thus, as the vacuum is applied the compressible component 108 moves from the relaxed state to the constricted state, and the barrier layers 112a, 112b also transition from the relaxed state to the constricted state. While the surfaces 110a, 110b may be attached to the barrier layers 112a, 112b at the peripheral seam 114, it is contemplated that the surfaces 110a, 110b may be otherwise unattached from the barrier layers 112a, 112b to provide fluid flow within the bladder 104 between the surfaces 110a, 110b and the barrier layers 112a, 112b. The adjustment element 102 also includes the channels 122, such that the barrier layers 112a, 112b have at least partial separation from the compressible component 108 even in the constricted state. The partial separation provided by the channels 122 between the barrier layers 112a, 112b and the compressible component 108 assists in fluid flow within the chamber 116.
For example, one or both of the surfaces 110a, 110b of the compressible component 108 may be detached from the barrier layers 112a, 112b. In this configuration, one or both of the barrier layers 112a, 112b are free to slide with respect to the surfaces 110a, 110b of the compressible component 108 as the compressible component 108 transitions between the relaxed state and the constricted state. For example, the barrier layers 112a, 112b are moved from the relaxed state to the constricted state when the barrier layers 112a, 112b are drawn into the reliefs 120, 120a under vacuum and are essentially pinched within the reliefs 120, 120a. In so doing, the pinched barrier layers 112a, 112b are essentially fixed for movement with the compressible component 108 due to being pinched within the reliefs 120, 120a and are transitioned into the constricted state along with the compressible component 108. When the vacuum is released, the resilient nature of the compressible component 108 returns the compressible component 108 to the relaxed or expanded state and, in so doing, exerts a force on the barrier layers 112a, 112b, thereby moving the barrier layers 112a, 112b from the constricted state to the relaxed or expanded state. The detachment or separation between the barrier layers 112a, 112b and the compressible component 108 may provide additional movement and flexibility of the bra 10 while in the relaxed state while still causing movement of the barrier layers 112a, 112b along with the compressible component 108 when the compressible component 108 is moved between the relaxed and constricted states. In some embodiments, one of the barrier layers 112a, 112b may be bonded to a corresponding layer 110a, 110b of the compressible component 108. During repeated contraction and relaxation, the outer and/or inner barrier layer 112b, 112a may not align with the corresponding surface 110b, 110a of the compressible component 108, which may cause a wrinkling appearance. In order to reduce movement of the outer barrier layer 112b or the inner barrier layer 112a with respect to the compressible component 108, the outer barrier layer 112b or the inner barrier layer 112a may be bonded to the compressible component 108. As a result, air flow through the plurality of channels occurs only via the side of the compressible component 108 that is not bonded to the barrier layer 112a or 112b.
In other implementations, at least one of the surfaces 110a, 110b of the compressible component 108 may be partially attached to the barrier layers 112a, 112b. For example, the compressible component 108 may be attached to the barrier layers 112a, 112b along a periphery of the surfaces 110a, 110b such that the interior region of the respective surface 110a, 110b is detached or independent from the barrier layers 112a, 112b. Thus, as the vacuum is applied and the compressible component 108 transitions from the relaxed state to the constricted state, the barrier layers 112a, 112b are influenced from the relaxed state to the constricted state under the applied vacuum by the outer periphery of the compressible component 108. For example, the barrier layers 112a, 112b may be attached to the compressible component 108 at the outer periphery or peripheral edge 114 of the compressible component 108. As such, when the vacuum is applied and the compressible component 108 translates toward the constricted state, the barrier layers 112a, 112b are drawn or otherwise compressed toward the compressible component 108 as a result of shrinkage or other compressive movement under vacuum of the outer periphery of the compressible component 108. Alternatively, at least one of the surfaces 110a, 110b of the compressible component 108 may be zonally attached to a respective one of the barrier layers 112a, 112b, which may then translate the surfaces 110a, 110b and the barrier layers 112a, 112b when the vacuum is drawn.
In FIG. 4A, the adjustment element 102 is in the relaxed state. As shown, the lattice structure 118 within the adjustment element 102 is expanded such that the reliefs 120 of the lattice structure 118 have a first width W120. To move the adjustment element 102 to the constricted state, pressure within the interior void 106 of the adjustment element 102 is reduced until a vacuum force overcomes the opposing biasing force imparted by the resilient material of the compressible component 108 and collapses the lattice structure 118 at the reliefs 120, transitioning the reliefs 120 from the expanded width W120 to a collapsed width W120.
Referring now to FIG. 6, the reliefs 120 of the compressible component 108 may include various structures including, but not limited to, diamond, wave, egg crate, and/or radial configuration, as described in more detail below. Each relief 120 includes an opening defined by relief walls surrounding a perimeter of the opening. For example, a parallelogram shaped relief comprises a parallelogram shaped opening defined by four side walls. For instance, reliefs 120 may be rectangular or parallelogram-shaped reliefs 120 including a length L120 extending across a first pair of opposing corners and a width W120 extending across a second pair of opposing corners that are arranged transverse (e.g., perpendicular) to the length L120. The compressible component 108 may include a single adjustment zone 124, such that the lattice structure 118 may uniformly adjust during application of the vacuum to the compressible component. In particular, the compressible component 108 may include a uniform lattice structure 118, such that each of the plurality of reliefs 120 that form the lattice structure 118 may have the same size. Additionally or alternatively, the lattice structure 118 may have variable adjustment depending on the fit of the bra 10 relative to the wearer. Stated differently and as described in more detail below, portions of the lattice structure 118 may be adjusted independently relative to other portions of the lattice structure 118 depending on the fit of the bra 10 relative to the wearer. For example, the perimeter cup region 54 may be adjusted independently of the central cup region 52. The compressible component 108 may further include a central element 126 corresponding to the center bridge 48 (FIG. 1) generally dividing the compressible component 108 into a right side 128 and a left side 130 corresponding to the right panel 46 and the left panel 50 of the front panel 44.
In the illustrated example, the width W120 of each relief 120 is less than the length Lim such that the reliefs 120 are configured to collapse along the widthwise direction when the pressure is reduced within the chamber 116 (FIG. 4B). Accordingly, orientations of the reliefs 120 may be selected depending on a desired transition profile between the expanded state and the constricted state. For example, the aspect ratio may be approximately 10 millimeters by approximately 15 millimeters. Alternatively, the aspect ratio of the reliefs 120 may be greater than approximately 10 millimeters by approximately 15 millimeters or may be less than approximately 10 millimeters by approximately 15 millimeters. The aspect ratio of the reliefs 120 may be generally dependent on the configuration, dimensions, and general shape of the reliefs 120, such that a range of aspect ratios is contemplated for the reliefs 120. Each of the reliefs 120 may be vertically aligned to form the compressible component 108, as illustrated in FIG. 6.
In one example, the reliefs 120 may have a generally diamond shape, as mentioned above. The diamond shape of the reliefs 120 may be any configuration, such that the reliefs may be narrow, large, small, wide, thin, square, rectangular, and/or any diamond shape. It is contemplated that the reliefs 120 may shrink along the x-axis and elongate along the y-axis during translation from the relaxed state to the constricted state. The percent shrinkage of the reliefs 120 along the x-axis may be between approximately 0.05 percent and approximately 62 percent, depending on the configuration of the reliefs 120. For example, the x-axis dimensions of the reliefs 120 may shrink as the vacuum within the bladder 104 (FIG. 4A) is increased. In one example, the x-axis dimensions of the reliefs 120 may shrink from approximately 160 millimeters to approximately 60 millimeters as the vacuum pressure is increased from 0 inches of mercury (inHg) to approximately 20 inHg. It is also contemplated that the percent elongation of the reliefs 120 along the y-axis may be between approximately 0.5 percent and approximately 15 percent.
Referring now to FIG. 7, the reliefs 120a of the compressible component 108a may be formed to include polygonal-shaped or circle-shaped apertures extending through the thickness T108a (FIG. 5A) of the compressible component 108a. As mentioned above, the compressible component 108a includes the lattice structure 118a including the plurality of reliefs 120a. For instance, reliefs 120a1 may be rectangular, diamond, parallelogram, or polygonal-shaped reliefs 120a1 including a length L120a1 extending across a first pair of opposing corners and a width W120a1 extending across a second pair of opposing corners that are arranged transverse (e.g., perpendicular) to the length L120a1. In the illustrated example, the width W120a1 of each relief 120a1 is less than the length L120a1 such that the reliefs 120a1 are configured to collapse along the widthwise direction when the pressure is reduced within the chamber 116. Accordingly, orientations of the reliefs 120a1 may be selected depending on a desired transition between the expanded state and the constricted state.
The reliefs 120a may further include circular or generally circle-shaped reliefs 120a2 having a diameter D120a2. In the illustrated example, the circle-shaped reliefs 120a2 are not configured to collapse when the pressure is reduced within the chamber 116 (FIG. 5B). The circle-shaped reliefs 120a2 may remain passive under the vacuum, compared to the contraction of the polygonal-shaped reliefs 120a1. It is contemplated that a combination of the circle-shaped reliefs 120a2 and the polygonal-shaped reliefs 120a1 may be positioned to generally correspond to the transition region 56 (FIG. 2) of the bra 10a, described in more detail below. Stated differently, the combination of the circle-shaped and polygonal-shaped reliefs 120a2, 120a1 may result in a lesser degree of contraction as compared to the polygonal-shaped reliefs 120a1 alone and a greater degree of contraction as compared to the circle-shaped reliefs 120a2 alone. While the circle-shaped reliefs 120a2 are generally passive, it is contemplated that the circle-shaped reliefs 120a2 may compress minimally to draw together any potential connecting portions of the lattice structure 118a between the circle-shaped reliefs 120a2. Accordingly, orientations of the reliefs 120a2 may be selected depending on a desired location for maintaining the relaxed state or expanded state.
In the illustrated example, the reliefs 120a of the compressible component 108a are arranged in a plurality of adjustment zones 124a1-124a3 to impart different transformation characteristics along the bra 10. For example, the compressible component 108a includes a first adjustment zone 124a1 arranged along the perimeter cup region 54 (FIG. 2) of the front panel 44 and including an array (e.g., rows and columns) of the reliefs 120a1 having the widths W120a1 oriented across a transverse direction (i.e., from the right side 20 to the left side 22) of the front panel 44 and the lengths L120a1 oriented along the longitudinal direction (i.e., from the upper end 16 to the lower end 18) of the front panel 44. Thus, the reliefs 120a1 of the first adjustment zone 124a1 are configured to selectively constrict the perimeter cup region 54 (FIG. 2) of the front panel 44 along the widthwise direction over the upper-torso of the wearer. The compressible component 108a may further include a central element 126 corresponding to the center bridge 48 (FIG. 2) and generally dividing the compressible component 108a into a right side 128 and a left side 130 corresponding to the right panel 46 and the left panel 50 of the front panel 44.
With continued reference to FIG. 7, the central portions of the compressible component 108a form a second adjustment zone 124a2 arranged in the central cup region 52 of the right panel 46 and the left panel 50 of the front panel 44. The second adjustment zone 124a2 includes an array of the reliefs 120a2 with diameters D120a2. The second adjustment zone 124a2 is configured to create a static or passive region within the bra 10a where the compressible component 108a and the front panel 44 do not contract or contract to a lesser extent than the first adjustment zone 124a1. Accordingly, the central cup region 52 maintains substantially the same shape whether the compressible component 108a is in the relaxed state or the contracted state. The compressible component 108a includes a third adjustment zone 124a3 formed in the transition region 56 between the perimeter cup region 54 and the central cup region 52. Here, the reliefs 120a include a combination of the reliefs 120a1 and 120a2 oriented in an alternating arrangement. Accordingly, the third adjustment zone 124a3 is configured to constrict the transition region 56 less than the perimeter cup region 54, but more than the central cup region 52 as the adjustment element 102a (FIG. 5A) is moved from the relaxed state to the constricted state.
With particular reference to FIG. 8, a compressible component 108b is provided. In view of the substantial similarity in structure and function of the components associated with the compressible component 108, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified.
In the illustrated example of FIG. 8, the compressible component 108b includes reliefs 120b, which are arranged in a plurality of adjustment zones 124b1, 124b2 to impart transition profiles having different transformation characteristics along the bra 10. For example, the compressible component 108b may include a first adjustment zone 124b1 arranged along the bottom region 56a of the front panel 44 and including an array (e.g., rows and columns) of reliefs 120b1 having widths W120b1 oriented across the frontal direction (i.e., from the right side 20 to the left side 22) of the front panel 44 and lengths L120b1 oriented along the longitudinal direction (i.e., from the central cup region 52 to the lower end 18) of the front panel 44. Thus, the reliefs 120b1 of the first adjustment zone 124b1 are configured to selectively constrict the bottom region 56a of the front panel 44 along the widthwise or frontal direction over the upper-torso of the wearer. The compressible component 108b may further include a central element 126 corresponding to the center bridge 48 and generally dividing the compressible component 108b into a right side 128 and a left side 130 corresponding to the right panel 46 and the left panel 50 of the front panel 44.
The compressible component 108b may include a second adjustment zone 124b2 arranged in an upper portion of the central cup region 52 and the upper region 56b of the front panel 44. The second adjustment zone 124b2 includes a semi-circular dead and/or static region 132b having a location corresponding to an upper half of an areola of a wearer and reliefs 120b2 arranged radially relative to the dead region 132b of the central cup region 52. Stated differently, the reliefs 120b2 are oriented in a transverse direction relative to the first reliefs 120b1. Here, the dead and/or static region 132b may also be a static region free from the reliefs 120b2. Accordingly, the second adjustment zone 124b2 may radially constrict while the static region 132b of the second adjustment zone 124b2 remains relaxed. Accordingly, an interior portion of the central cup region 52 may maintain substantially the same shape whether the compressible component 108b is in the relaxed state or the constricted state.
It is generally contemplated that the first adjustment zone 124b1 and the second adjustment zone 124b2 may correspond to the first and second zones, respectively, of the bladder 104 as mentioned above. The first zone 124b1, the outer barrier layer 112b (FIG. 4A), the inner barrier layer 112a, and the compressible component 108b may be fused along a first zone perimeter or barrier 134b. The first zone 124b1, the second surface 110b, and the outer layer 112b are separate from each other except at the first zone perimeter 134b, and the first surface 110a and the inner layer 112a are separate from each other except at the first zone perimeter 134b. At the second zone 124b2, the second surface 110b may be fused with the outer layer 112b at one or more regions and the first surface 110a may be fused with the inner layer 112a at the one or more regions. Additionally or alternatively, at the second zone 124b2, the second surface 110b may be fully fused with the outer layer 112b and the first surface 110a may be fully fused with the inner layer 112a.
With particular reference to FIG. 9, a compressible component 108c is provided. In view of the substantial similarity in structure and function of the components associated with the compressible component 108, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified. The compressible component 108c illustrated in FIG. 9 includes reliefs 120c and a single adjustment zone 124c radially extending from a static region 132c of the central cup region 52 of the front panel 44. As mentioned with respect to FIG. 8, the static region 132c illustrated in FIG. 9 may remain substantially relaxed while the adjustment zone 124c radially constricts the reliefs 120c about the static region 132c in the constricted state of the compressible component 108c.
With particular reference to FIGS. 10A-10C, a compressible component 108d is provided. In view of the substantial similarity in structure and function of the components associated with the compressible component 108, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified.
The compressible component 108d illustrated in FIGS. 10A-10C includes a lattice structure 118d with reliefs 120d and a single adjustment zone 124d extending from a static region 132d. The static region 132d illustrated in FIGS. 10A-10C may remain substantially relaxed while the adjustment zone 124d constricts the reliefs 120d about the static region 132d in the constricted state of the compressible component 108d. It is contemplated that the static region 132d may correspond with either the bottom region 56a or the upper region 56b of the front panel 44. For example, the static region 132d is illustrated in FIG. 10A along the bottom region 56a of the front panel 44 with the adjustment zone 124d formed along the upper region 56b of the front panel 44. Alternatively, FIG. 10B illustrates the static region 132d along the upper region 56b of the front panel 44 with the adjustment zone 124d formed along the bottom region 56a of the front panel 44. In either configuration the static region 132d is fluidly sealed from or otherwise impermeable relative to the adjustment zone 124d via a barrier 134d, such that when a vacuum is drawn in the adjustment zone 124d the static region 132d remains generally unaffected by the drawn vacuum and there is no fluid communication between the static region 132d and the adjustment zone 124d. Additionally or alternatively, the barrier 134d may be formed from an impermeable coating at a junction between the static region 132d and the adjustment zone 124d. The impermeable coating or barrier 134d is configured to prevent fluid communication between the static region 132d and the adjustment zone 124d.
FIG. 10C illustrates an alternate configuration of the compressible component 108d with the lattice structure 118d disposed within both the adjustment zone 124d and the static region 132d of the compressible component 108d. It is contemplated that the portion of the lattice structure 118d disposed within the static region 132d is free from fluid communication with the portion of the lattice structure 118d disposed within the adjustment zone 124d. In this configuration the static region 132d may include a plurality of apertures 136d within the reliefs 120d, such that the apertures 136d may provide fluid flow to advantageously promote breathability of the static region 132d. For example, the apertures 136d are illustrated along a perimeter 138d of the upper region 56b within the reliefs 120d. Additionally or alternatively, the apertures 136d may be formed along the entire static region 132d or in select portions other than the perimeter 138d. As mentioned above, the static region 132d is sealed from the adjustment zone 124d via the barrier 134d. The fluid flow provided by the apertures 136d is configured to assist in breathability of the compressible component 108d where the lattice structure 118d extends into the static region 132d. Where the static region 132d is free from the lattice structure 118d, it is contemplated that the static region 132d of the compressible component 108d may be formed from a breathable material. For example, the breathable material of the static region 132d may form-fit with the wearer while remaining flexible. By way of example, not limitation, the static region 132d may be formed from spandex, lycra, and other practicable materials and combinations thereof.
With particular reference to FIG. 11, a compressible component 108e is provided. In view of the substantial similarity in structure and function of the components associated with the compressible component 108, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified.
The compressible component 108e illustrated in FIG. 11 includes a lattice structure 118e including reliefs 120e and a single adjustment zone 124e extending from a static region 132e of the front panel 44. The reliefs 120e are radially oriented to form the adjustment zone 124e. The static region 132e illustrated in FIG. 11 is free from the lattice structure 118e and may remain substantially relaxed while the adjustment zone 124e radially constricts the reliefs 120e about the static region 132e in the constricted state of the compressible component 108e. For example, the static region 132e may be formed from a breathable material being form-fit with the wearer while remaining flexible. By way of example, not limitation, the static region 132e may be formed from spandex, lycra, and other practicable materials and combinations thereof. Alternatively, the lattice structure 118e may extend into the static region 132e, as described above with respect to FIG. 10C. In either configuration, the static region 132e is fluidly sealed from the adjustment zone 124e via a barrier 134e to prevent fluid communication between the adjustment zone 124e and the static region 132e. It is contemplated that the static region 132e may correspond with either the bottom region 56a or the upper region 56b of the front panel 44. For example, the static region 132e is illustrated in FIG. 11 as the bottom region 56a of the front panel 44 with the adjustment zone 124e formed along the upper region 56b of the front panel 44. Alternatively, the static region 132e may be configured as the upper region 56b of the front panel 44 with the adjustment zone 124e formed along the bottom region 56a of the front panel 44. The adjustment zone 124e is configured as radially extending from the static region 132e.
With particular reference to FIG. 12, a compressible component 108f is provided. In view of the substantial similarity in structure and function of the components associated with the compressible component 108, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified.
The compressible component 108f illustrated in FIG. 12 has an adjustment zone 124f disposed along a portion of a perimeter 138f of the compressible component 108f, to generally define a W-shaped configuration. Stated differently, the adjustment zone 124f is formed around a static region 132f, which generally corresponds to the central cup region 52 (FIG. 1) of the bra 10 and a portion of the upper region 56b of the front panel 44. It is contemplated that a lattice structure 118f of the compressible component 108f is disposed within the adjustment zone 124f to translate, at least in part, the adjustment zone 124f between a relaxed state and a constricted state, while the static region 132f is generally free from the lattice structure 118f. Alternatively, the static region 132f may be formed as an extension of the lattice structure 118f, such that the static region 132f may include the lattice structure 118f. Where the static region 132f is free from the lattice structure 118f, it is contemplated that the static region 132f of the compressible component 108f may be formed from a breathable material. For example, the static region 132f may be formed from a breathable material having a form-fit with the wearer while remaining flexible. By way of example, not limitation, the static region 132f may be formed from spandex, lycra, and other practicable materials and combinations thereof. It is generally contemplated that the static region 132f is fluidly sealed from or otherwise impermeable relative to the adjustment zone 124f via a barrier 134f, such that when a vacuum is drawn in the adjustment zone 124f the static region 132f remains generally unaffected by the drawn vacuum and there is no fluid communication between the static region 132f and the adjustment zone 124f. Additionally or alternatively, the barrier 134f may be formed from an impermeable coating at a junction between the static region 132f and the adjustment zone 124f. The impermeable coating or barrier 134f is configured to prevent fluid communication between the static region 132e and the adjustment zone 124f.
With particular reference to FIGS. 13A and 13B, a compressible component 108g is provided. In view of the substantial similarity in structure and function of the components associated with the compressible component 108, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified.
The compressible component 108g illustrated in FIG. 13A has an adjustment zone 124g1 disposed along a perimeter 138g of the compressible component 108g and including a lattice structure 118g with reliefs 120g1. A static region 132g is generally surrounded by the adjustment zone 124g1 and generally corresponds to the central cup region 52 of the bra 10 (FIG. 1). It is contemplated that the lattice structure 118g of the compressible component 108g is disposed within the adjustment zone 124g1 to translate, in part, the adjustment zone 124g1 between a relaxed state and a constricted state, while the static region 132g is generally free from the lattice structure 118g. Alternatively, the static region 132g may be formed as an extension of the lattice structure 118g, such that the static region 132g may include the lattice structure 118g. Where the static region 132g is free from the lattice structure 118g, it is contemplated that the static region 132g of the compressible component 108g may be formed from a breathable material. For example, the static region 132g may be formed from a breathable material having a form-fit with the wearer while remaining flexible. By way of example, not limitation, the static region 132g may be formed from spandex, lycra, and other practicable materials and combinations thereof. In either configuration, it is generally contemplated that the static region 132g is fluidly sealed from or otherwise impermeable relative to the adjustment zone 124g1 via a barrier 134g, such that when a vacuum is drawn in the adjustment zone 124g1 the static region 132g remains generally unaffected by the drawn vacuum and there is no fluid communication between the static region 132g and the adjustment zone 124g1. Additionally or alternatively, the barrier 134g may be formed from an impermeable coating at a junction between the static region 132g and the adjustment zone 124g1. The impermeable coating or barrier 134g is configured to prevent fluid communication between the static region 132g and the adjustment zone 124g1. It is generally contemplated that the static region 132g is sealed or otherwise impermeable relative to the adjustment zone 124g1 via the barrier 134g, such that when a vacuum is drawn in the adjustment zone 124g the static region 132g remains generally unaffected by the drawn vacuum. The barrier 134g is configured to prevent fluid communication between the static region 132g and the adjustment zone 124g1.
An alternate configuration of the compressible component 108g is illustrated in FIG. 13B with an adjustment zone 124g2 disposed along the perimeter 138g of the compressible component 108g. The adjustment zone 124g2 includes reliefs 120g2 of the lattice structure 118g radially oriented around the static region 132g. The radial extension of the reliefs 120g2 may assist in form-fitting the compressible component 108g with the wearer. State differently, the reliefs 120g2 of the lattice structure 118g may have a radial orientation relative to the static region 132g to extend in a radial direction about the static region 132g.
With particular reference to FIG. 14, a compressible component 108h is provided. In view of the substantial similarity in structure and function of the components associated with the compressible component 108, like reference numerals are used hereinafter and in the drawings to identify like components while like reference numerals containing letter extensions are used to identify those components that have been modified.
The compressible component 108h illustrated in FIG. 14 has a static region 132h disposed along a perimeter 138h of the compressible component 108h around an adjustment zone 124h. The adjustment zone 124h generally corresponds to the central cup region 52 of the bra 10 (FIG. 1). It is contemplated that a lattice structure 118h of the compressible component 108h is disposed within the adjustment zone 124h to translate, in part, the adjustment zone 124h between a relaxed state and a constricted state, while the static region 132h is generally free from the lattice structure 118h. Alternatively, the static region 132h may be formed as an extension of the lattice structure 118h, such that the static region 132h may include the lattice structure 118h. Where the static region 132h is free from the lattice structure 118h, it is contemplated that the static region 132h of the compressible component 108h may be formed from a breathable material. For example, the static region 132h may be formed from a breathable material having a form-fit with the wearer while remaining flexible. By way of example, not limitation, the static region 132h may be formed from spandex, lycra, and other practicable materials and combinations thereof. In either configuration, it is generally contemplated that the static region 132h is fluidly sealed from or otherwise impermeable relative to the adjustment zone 124h via a barrier 134h, such that when a vacuum is drawn in the adjustment zone 124h the static region 132h remains generally unaffected by the drawn vacuum and there is no fluid communication between the static region 132h and the adjustment zone 124h. Additionally or alternatively, the barrier 134h may be formed from an impermeable coating at a junction between the static region 132h and the adjustment zone 124h. The impermeable coating or barrier 134h is configured to prevent fluid communication between the static region 132h and the adjustment zone 124h. It is generally contemplated that the static region 132h is sealed or otherwise impermeable relative to the adjustment zone 124h via the barrier 134h, such that when a vacuum is drawn in the adjustment zone 124h the static region 132h remains generally unaffected by the drawn vacuum. The barrier 134h is configured to prevent fluid communication between the static region 132h and the adjustment zone 124h.
It is further contemplated that any one of the compressible components 108-108h described herein may be incorporated in any portion of the bra 10. For example, the compressible component 108-108h may be incorporated as part of the rear panel 62 in addition or alternative to the front panel 44. The addition of the compressible component 108-108h along the rear panel 62 may further assist in providing support for the wearer by drawing the vacuum to compress the reliefs 120-120h of the lattice structure 118-118h. It is also contemplated that the compressible components 108-108h may be incorporated in other portions of the bra 10 including, but not limited to, the straps 64 in combination with or independently of the front panel 44 and the rear panel 62. The adjustment provided by the placement of the compressible components 108-108h may advantageously assist in providing additional comfort for the wearer as a result of the customized compression formed by the vacuum compressing or otherwise constricting the lattice structure 118-118h of the respective compressible component 108-108h.
In any one of these contemplated configurations, the chamber 116, in which the respective compressible component 108-108h is disposed, is sealed from other regions of the bra 10. For example, the adjustment zones 124-124h may be sealed by welding or otherwise sealing off individual reliefs 120-120h that border the first and second adjustment zones 124-124h. The reliefs 120-120h proximate to the static region 132a-132h may also be sealed to minimize fluid flow proximate to and prevent fluid-flow within the static regions 132a-132h.
In one example, the compressible components 108-108h may be configured with additional static regions 132a-132h, such that additional portions of the compressible components 108-108h may be static or otherwise free from reliefs 120, as described above. Stated differently, the compressible components 108-108h may include, in addition to those described above, regions with the lattice structure 118 (e.g., the adjustment zone(s) 124-124h) and regions that are free from the lattice structure 118 (e.g., the static regions 132a-132h). By way of example, not limitation, each of the compressible components 108-108h described herein may be disposed within the bladder 104 and may be sealed or otherwise segmented into the adjustment zone(s) 124-124h to advantageously provide various compression configurations. It is also contemplated that the compressible components 108-108h with one or more of the adjustment zone(s) 124-124h, may be disposed in a bottom portion, a top portion, an annular portion of the cups 58, 60, and/or any combination thereof. Optionally, the bra 10 may include one or more bladders 104 that provide the adjustment zone(s) 124-124h. In such a configuration, the one or more bladders 104 are assembled to form the bra 10.
The compressible components 108-108h include one or more resilient materials configured to bias the adjustment element 102 towards the expanded or relaxed state. For example, the compressible components 108-108h may include an elastomeric material, such as the EVA foam. In one example, the EVA foam may have a thickness of approximately 6 millimeters. Alternatively, the thickness of the EVA foam may be greater than or less than approximately 2 millimeters to approximately 10 millimeters. In other examples, the compressible components 108-108h may include unfoamed polymers, such as thermoplastic polyurethane. Optionally, the compressible components 108-108h may include fiber-reinforced elastomeric materials. By way of example, not limitation, the compressible components 108-108h may include a TPU textile composite. In some implementations, the compressible components 108-108h may be formed from 3D printing. In addition to including different materials, the lattice structure 118 may include different geometrical configurations to impart different constriction profiles in different areas of the adjustment element 102. Optionally, a thickness of the compressible components 108-108h ranges from 4 millimeters to 8 millimeters to provide the adjustment element 102 with a relatively low profile while also providing sufficient structural strength for biasing the adjustment element 102 to the expanded or relaxed state.
Referring to FIGS. 15A-17B, an example of a port 200 and a pump 202 utilized for adjusting a pressure of the bladder 104 of the bra 10 is provided. The port 200 may be coupled to the bladder 104 and operable to selectively permit fluid communication with the bladder space or interior void 106. The port 200 includes a flange 204 extending from a body 206 that includes an aperture 208. The flange 204 may be utilized to couple the port 200 to the center bridge 48 (FIG. 1) and the central element 126. For example, the port 200 may be welded to the center bridge 48 at the flange 204. An actuator 210 is disposed within the aperture 208 and is coupled to a biasing member 212 (FIG. 15B). The biasing member 212 is configured to bias the actuator 210 from an open position in which fluid may enter or exit the port 200 to a closed position in which the port 200 is sealed. As shown, the body 206 includes an outer or upper rim 214a extending from a first side of the flange 204 and an inner or lower rim 214b extending from an opposite second side of the flange 204. Fluid channels 216 are disposed along the rims 214a, 214b of the body 206 to promote fluid communication and/or movement and minimize potential obstruction during engagement of the actuator 210. For example, the wearer may compress the actuator 210 to release the fluid from the chamber 116, illustrated in FIG. 15C, and the fluid channels 216 assist in the movement of the fluid from the port 200. As mentioned above, the first zone of the bladder 104 is configured for selective fluid communication between the interior space of the first zone and the atmosphere and/or the pump 202 via the port 200. Additionally or alternatively, the second zone of the bladder 104 may be sealed from the first zone and the port 200.
While described herein in relation to the bra 10, it is appreciated that the port 200 may be utilized in various articles including, but not limited to, shoes, backpacks, bags, shirts, and/or other articles of apparel. Further, the port 200 could be used in conjunction with other similar articles such as the bra 10a (FIG. 2) described above. It is also contemplated that the port 200 may be utilized in inflating and/or deflating the bladder 104, the bra 10, and/or any other article incorporated with the port 200. As discussed previously, the bra 10 is moved between the relaxed state and the constricted state by adjusting a fluid pressure within the interior void 106. For example, the pressure within the interior void 106 may be reduced by drawing a vacuum within the interior void 106 through the port 200 attached to the bladder 104. It is contemplated that the port 200 and the compressible component 108 may be at least partially separated by a pliable member 140. The pliable member 140 may be formed from an EVA material, and the channels 122 disposed along the compressible component 108 may extend through the pliable members 140 to define the fluid path between the port 200 and each of the reliefs 120 of the compressible component 108. The vacuum may be drawn using a pressure source, such as a pump 202 integrated within the bra 10 or provided as a peripheral (i.e., independent) accessory to the bra 10. However, the pump 202 may be attached or disposed in any portion of the bras 10, 10a, such as on the front panel 44, the straps 64, or in other regions of the bras 10, 10a. Further, the pump 202 may be a peripheral accessory not attached to the bra 10, such as an accessory pump exterior to and free from attachment with the bra 10. It is contemplated that the pump 202 may include, but is not limited to, an accessory pump that may be applied to the port 200, a clam-shell pump having an internal envelope that assists in drawing the vacuum, and/or a pump incorporated in one of the panels 44, 62 of the bra 10. The term pump 202 refers to drawing the vacuum within the chamber 116 of the adjustment element 102, such that the pump 202 pumps or otherwise draws the vacuum via automatic or manual components. By way of example, not limitation, where the pump 202 is an accessory pump, the pump 202 may include a cartridge configured with a preset vacuum to automatically draw the vacuum when the pump 202 is applied to the port 200.
Referring to FIGS. 15A-16C, during evacuation of the chamber 116, a tip or nozzle of the pump 202 is configured to receive the body 206 of the port 200 and is disposed around and generally seals the fluid channels 216. For example, the pump 202 includes a seal 218 that is coupled with the body 206 when the pump 202 is disposed over the port 200. In this configuration, fluid is drawn from the port 200 and minimizes backflow by sealing or otherwise obstructing the fluid channels 216 external to the chamber 116, as illustrated in FIG. 15C.
Referring to FIGS. 17A and 17B, an example of using the port 200 and the pump 202 to adjust the bra 10 is provided. As the pressure is reduced (e.g., below ambient) within the interior void 106, the lattice structure 118 collapses along the width-wise directions of the reliefs while the front panel 44 constricts around the upper-torso (FIG. 17B). Conversely, to move the bra 10 to the relaxed state, the pressure within the interior void 106 is increased and the resilient material and/or geometry of the lattice structure 118 biases the bra 10 towards the expanded state (FIG. 17A). It is contemplated that one or more intermediate states may be achieved when the compressible component 108 transitions between the relaxed state and the contracted state and vice versa. In one example, the wearer may selectively contract and/or relax the compressible component 108, such that the compressible component 108 may statically remain in one of the one or more intermediate state. In an alternate aspect, the right and left sides 128, 130 of the compressible components 108 may be independently and selectively adjustable. For example, the right side 20 of the bra 10 may be sealed relative to the left side 22 of the bra 10, and the wearer may selectively evacuate the adjustment element 102 to compress one of the right and/or left sides 128, 130 of the compressible component 108. In this configuration, it is contemplated that the bra 10 may include multiple ports 200 to selectively compress the right and/or left sides 128, 130 of the compressible component 108 independently, such that one side of the compressible component 108 may compress to a greater or lesser extent compared to the adjacent and/or opposing side of the compressible component 108.
Referring to FIGS. 18A and 18B and as mentioned above, the pump 202 is utilized to draw a vacuum via the port 200 to compress or otherwise constrict the reliefs 120a1, such that the width W120a1 reduces under the vacuum. The reduced width W120a1 results in a constriction of the bra 10a about the wearer in the first and third adjustment zones 124a1, 124a3. The constriction of the bra 10a at the first and third adjustment zones 124a1, 124a3 advantageously provides support for the wearer and constriction in the perimeter cup and transition regions 54, 56, respectively. It is contemplated that the portions of the upper-torso of the wearer that are generally proximate to and covered by the perimeter cup and transition regions 54, 56 are less sensitive, such that greater compression may be utilized as compared to the central cup region 52. Additionally or alternatively, each of the central cup, perimeter cup, and transition regions 52, 54, 56 may have a degree of constriction under the vacuum pressure, such that the upper-torso of the wearer is generally secured to minimize potential vertical movement of the upper-torso. As mentioned above, portions of the second adjustment zone 124a2 may compress to a lesser degree compared to the first and third adjustment zones 124a1, 124a3 to provide additional support for the wearer while minimizing the overall compressive force in the central cup region 52 of the bra 10a. While it is contemplated that some degree of compression may occur in the second adjustment zone 124a2, it is also contemplated that the second adjustment zone 124a2 may remain static, such that the reliefs 120a2 remain stationary during the transition of the adjustment element 102a from the relaxed state (FIG. 18A) to the constricted state (FIG. 18B).
Referring again to FIGS. 1-19, the bra 10 may provide compressive support by utilizing the adjustment element 102. As compared to a standard bra, the adjustment element 102 of the bra 10, as described herein, utilizes the compression formed by drawing the vacuum to form a custom fit for the wearer. The arrangement of the reliefs 120 of the compressible component 108 may advantageously include the adjustment zone(s) 124 to provide customized support and/or compression for the wearer. For example, the reliefs 120 may be arranged in a radial configuration and/or an array configuration. The bra 10 also includes the port 200 to advantageously provide selective evacuation and release of the adjustment element 102. The wearer may utilize the pump 202 to draw the at least partial vacuum within the interior void 106 of the adjustment element 102 to compress or otherwise contract the compressible component 108.
For example, and with reference to FIG. 19, a method (1000) of operating the bra 10 is provided. The wearer may apply the pump 202 to the port 200 to draw an at least partial vacuum within the bladder 104 of the adjustment element 102 (step 1002). The pump 202 compresses the actuator 210 of the port 200 to allow the pump 202 to be in fluid communication with the interior void 106 of the bladder 104. Once in fluid communication with the interior void 106, the pump 202 is able to remove fluid from the bladder 104 and adjust the pressure of the interior void 106 of the chamber 116. When the pressure within the interior void 106 is sufficiently reduced by removing a predetermined volume of fluid, compression of the compressible component 108 (step 1004) is achieved. The wearer removes the pump 202 once a desired compression is achieved, and the actuator 210 is biased to a closed state to seal the port 200 (step 1006). Optionally, the wearer may adjust the pressure within the chamber 116 by depressing the actuator 210 to allow fluid to enter the interior void 106 and release the compression defining the intermediate state of the compressible component 108 (step 1008). The wearer may repeatedly adjust the compressible component 108 using the pump 202 and may depress the actuator 210 to achieve a custom state of the compressible component 108 and custom fit of the bra 10.
A method of manufacturing includes laser etching and subsequently thermoforming the compressible component 108 to define the lattice structure 118. The compressible component 108 may then be positioned between the first and second barrier layers 112a, 112b and the bladder 104 may be defined to form the adjustment element 102. The barrier layers 112a, 112b may be sealed along the peripheral seam 114 to form the interior void 106 in which the compressible component 108 may be disposed.
In one example, method of manufacturing an article of apparel comprises forming an outer barrier layer and an inner barrier layer of a bladder; forming a compressible component, the compressible component including a first zone, the first zone operable between a contracted state and a relaxed state; coupling the outer barrier layer, the compressible component, and the inner barrier layer at a peripheral edge of the bladder; and fluidly coupling a port to the bladder, the port operable to selectively permit fluid communication between the compressible component and the bladder. Further, forming the inner barrier layer, the outer barrier layer, and the compressible component includes forming each of the inner barrier layer, the outer barrier layer and the compressible component into a three-dimensional shape. In one example, forming the compressible component includes laser cutting the compressible component to form a plurality of reliefs in the first zone and then, thermoforming the compressible component into the three-dimensional shape.
