DETAILED DESCRIPTION OF EMBODIMENTS
[0078]
[0079] As further discussed below, in this embodiment, the athletic gear 11 provides enhanced moisture management to deal with sweat produced by the player's body. Notably, in this embodiment, the athletic gear 11 has a quick-drying capability to increase a rate of evaporation of moisture within a micro-climate of the player. This is particularly useful in view of the protective athletic equipment 12 worn by the player that increases sweating and humidity and reduces air circulation about the player's upper body. In other words, the quick-drying capability of the athletic gear 11 helps to deal with the player's micro-climate that is affected by the protective athletic equipment 12.
1. Athletic Garment
[0080] The shirt 10 comprises an inner surface 17 for facing towards the player and an outer surface 19 for facing away from the player. In this embodiment in which the shirt 10 is a baselayer shirt to be worn under the protective athletic equipment 12, the inner surface 17 is configured to contact the player's body and the outer surface 19 is configured to contact the protective athletic equipment 12.
[0081] The shirt 10 comprises a torso portion 14 including a front 16, a back 18, a top opening 20 for passing a neck and head of the player, and a lower opening 22 for fitting around a lower torso region (e.g., a waist and hips) of the player. In this embodiment, the shirt 10 also comprises a pair of sleeves 24.sub.1, 24.sub.2 for receiving arms of the player. In this example, the sleeves 24.sub.1, 24.sub.2 are long sleeves extending to wrists of the player. The sleeves 24.sub.1, 24.sub.2 may be short sleeves (e.g., the shirt 10 may be a T-shirt) in other examples. In other embodiments, the shirt 10 may be sleeveless.
[0082] The shirt 10 comprises a material 30 making up at least part of the shirt 10. That is, the shirt 10 is at least partly (i.e., partly or entirely) made of the material 30. In this embodiment, the shirt 10 is at least mainly (i.e., mainly or entirely) made of the material 30. More particularly, in this embodiment, the material 30 makes up at least part of the torso portion 14 and each of the sleeves 24.sub.1, 24.sub.2.
[0083] In this embodiment, with additional reference to
[0084] In this example of implementation, the shirt 10 is a compression shirt, i.e., a form-fitting shirt that has a compression fit when worn by the player. This may help to keep muscles warm to reduce muscle strain and fatigue, wick sweat away from the player's body, and prevent or reduce chafing and rashes. To that end, the fibers 31.sub.1-31.sub.F of the fabric 30 may include spandex (elastane) fibers or other stretchable fibers having suitable elasticity. The shirt 10 may not be a compression shirt in other examples of implementation.
[0085] For example, in this embodiment, the fibers 31.sub.1-31.sub.F of the fabric 30 include polyester and spandex fibers. For instance, the fabric 30 may comprise at least 75% polyester fibers and at least 10% spandex fibers (e.g., the fabric 30 may comprise 87% 75D/72F or 75D/48F textured polyester and 13% 40 denier spandex, may be a single jersey construction weighing 155 g/m.sup.2, and may have wicking finish applied to it). The fabric 30 may have any other suitable composition in other embodiments.
[0086] The fabric 30 is configured taking into account an interface between the shirt 10 and the protective athletic equipment 12 worn by the player. Notably, the fabric 30 has mechanical properties to resist tearing or other excessive damage due to friction or other contact between the shirt 10 and the protective athletic equipment 12. For example, in some embodiments, the fabric 30 may have an abrasion resistance of at least 10000 rubs according to ASTM 4966Option 1. As another example, in some embodiments, the fabric 30 may have a bursting strength of at least 40 psi if the fabric 30 weighs 3.4 oz./yd..sup.2 or less, or at least 55 psi if the fabric 30 weighs 3.5 oz./yd..sup.2 or more, according to ASTM D3788. As another example, in some embodiments, the fabric 30 may have a snagging resistance of at least 3 according to ASTM D3939 (Mace Snap). These properties of the fabric 30 may have any other suitable values in other embodiments.
[0087] In this embodiment, the fabric 30 is a quick-drying material, i.e., a material exhibiting a drying rate which is relatively high, to quickly evaporate moisture as the player sweats. For example, in some embodiments, the drying rate of the fabric 30 may be at least 2.1 ml/hr, in some cases at least 2.3 ml/hr, in some cases at least 2.5 ml/hr, and in some cases even more, according to AATCC Test Method 201 of the American Association of Textile Chemists and Colorists (AATCC). Alternatively or additionally, in some embodiments, the drying rate of the fabric 30 may be at least 15 ml/hr, in some cases at least 20 ml/hr, in some cases at least 25 ml/hr, and in some cases even more, according to AATCC Test Method 200 of the AATCC. The drying rate of the fabric 30 may have any other suitable value in other embodiments.
[0088] More particularly, in this embodiment, to facilitate moisture evaporation, the fabric 30 is configured to (1) spread moisture over a large surface area and (2) harness heat generated by the player's body to vaporize liquid moisture.
[0089] For example, in some embodiments, a surface area of the fabric 30 may be at least 300 cm.sup.2 per square centimeter of fabric, in some cases at least 400 cm.sup.2 per square centimeter of fabric, in some cases at least 500 cm.sup.2 per square centimeter of fabric, in some cases at least 600 cm.sup.2 per square centimeter of fabric, and in some cases even more. Alternatively or additionally, in some embodiments, a surface area of a constituent of the fabric 30 may be at least 200 m.sup.2 per gram of the constituent, in some cases at least 400 m.sup.2 per gram of the constituent, in some cases at least 600 m.sup.2 per gram of the constituent, in some cases at least 800 m.sup.2 per gram of the constituent, in some cases at least 1000 m.sup.2 per gram of the constituent and in some cases even more. The surface area of the constituent of the fabric 30 may have any other suitable value in other embodiments.
[0090] To harness heat generated by the player's body to vaporize moisture, a constituent of the fabric 30 captures this heat to raise its temperature and cause vaporization of liquid moisture in contact with it. For example, in some embodiments, a specific heat capacity of a constituent of the fabric 30 (i.e., an amount of heat required to increase the temperature of a unit mass of the constituent of the fabric 30 by one degree) may be relatively low. For instance, in some embodiments, the specific heat capacity of the constituent of the fabric 30 may be less than polyester's specific heat capacity and less than spandex's specific heat capacity. The specific heat capacity of the constituent of the fabric 30 may have any other suitable value in other embodiments. Additionally or alternatively, in some embodiments, a molar absorptivity at an infrared wavelength of a constituent of the fabric 30 (i.e., a measurement of how strongly a chemical species of the constituent of the fabric 30 absorbs electromagnetic radiation at the infrared wavelength) may be relatively high. For instance, in some embodiments, the molar absorptivity at an infrared wavelength of the constituent of the fabric 30 may be greater than polyester's molar absorptivity at that infrared wavelength and greater than spandex's molar absorptivity at that infrared wavelength. The molar absorptivity at the infrared wavelength of the constituent of the fabric 30 may have any other suitable value in other embodiments.
[0091] Also, in some embodiments, a constituent of the fabric 30 may be configured to manifest an exothermic reaction releasing heat to accelerate the drying process. That is, a constituent of the fabric 30 may be configured to exothermically react (i.e., produce heat when reacting) with liquid moisture. The exothermic reaction may be chemical and/or physical. For example, in some embodiments, the exothermic reaction manifested by the constituent of the fabric 30 may be adsorption of liquid moisture by the constituent of the fabric 30, such that heat is released when the liquid moisture is adsorbed by the constituent of the fabric 30.
[0092] With additional reference to
[0093] In this example of implementation, the active elements 40.sub.1-40.sub.P are connected to the fibers 33.sub.1-33.sub.K of the fibrous base substance 29. In other examples of implementation, the fibers 33.sub.1-33.sub.K of the fabric 30 may themselves be the active elements 40.sub.1-40.sub.P that enhance the drying process of the fabric 30 on their own, without having distinct active elements connected to the fibers 33.sub.1-33.sub.K.
[0094] More particularly, in this embodiment, the active elements 40.sub.1-40.sub.P are active particles distributed within the fabric 30. In this example, the active particles 40.sub.1-40.sub.P have an adsorptive property that causes them to adsorb liquid moisture as the player sweats. This reaction, i.e., adsorption, caused by the active particles 40.sub.1-40.sub.P helps evaporating the liquid moisture.
[0095] With additional reference to
[0096] Because of their pores 42.sub.1-42.sub.T, the active particles 40.sub.1-40.sub.P have a surface area which is very large, thereby vastly spreading the liquid moisture to aid evaporating it. For example, in some embodiments, the surface area of the active particles 40.sub.1-40.sub.P may be such that the surface area of the fabric 30 is at least 300 cm.sup.2 per square centimeter of fabric, in some cases at least 400 cm.sup.2 per square centimeter of fabric, in some cases at least 500 cm.sup.2 per square centimeter of fabric, in some cases at least 600 cm.sup.2 per square centimeter of fabric, and in some cases even more. Alternatively or additionally, in some embodiments, the surface area of the active particles 40.sub.1-40.sub.P may be at least 200 m.sup.2 per gram of active particle, in some cases at least 400 m.sup.2 per gram of active particle, in some cases at least 600 m.sup.2 per gram of active particle, in some cases at least 800 m.sup.2 per gram of active particle, in some cases at least 1000 m.sup.2 per gram of active particle and in some cases even more. The surface area of the active particles 40.sub.1-40.sub.P may have any other suitable value in other embodiments.
[0097] Also, in this embodiment, the active particles 40.sub.1-40.sub.P use heat generated by the player's body to vaporize moisture. For example, in some embodiments, a specific heat capacity of the active particles 40.sub.1-40.sub.P may be relatively low. For instance, in some embodiments, the specific heat capacity of the active particles 40.sub.1-40.sub.P may be less than a specific heat capacity of the fibrous base substance 29 of the fabric 30. Thus, in this example, the specific heat capacity of the active particles 40.sub.1-40.sub.P may be less than polyester's specific heat capacity and less than spandex's specific heat capacity. The specific heat capacity of the active particles 40.sub.1-40.sub.P may have any other suitable value in other embodiments. Additionally or alternatively, in some embodiments, a molar absorptivity at an infrared wavelength of the active particles 40.sub.1-40.sub.P may be relatively high. For instance, in some embodiments, the molar absorptivity at an infrared wavelength of the active particles 40.sub.1-40.sub.P may be greater than a molar absorptivity at that infrared wavelength of the fibrous base substance 29 of the fabric 30. For instance, in some embodiments, the molar absorptivity at an infrared wavelength of the active particles 40.sub.1-40.sub.P may be greater than polyester's molar absorptivity at that infrared wavelength and greater than spandex's molar absorptivity at that infrared wavelength. The molar absorptivity at the infrared wavelength of the active particles 40.sub.1-40.sub.P may have any other suitable value in other embodiments.
[0098] Furthermore, the adsorption of liquid moisture by the active particles 40.sub.1-40.sub.P is an exothermic reaction releasing heat that helps to accelerate the drying process.
[0099] The active particles 40.sub.1-40.sub.P may be implemented in any suitable way. In this embodiment, the active particles 40.sub.1-40.sub.P comprise activated carbon. The activated carbon may be produced in various known ways. For instance, the activated carbon may be produced from carbonaceous materials such as wood, nutshells, coconut husk, coir, peat, lignite, coal, or other carbonaceous substances using known processes (e.g., physical reactivation using hot gases which involves carbonization and/or oxidation, or chemical activation using chemicals on raw material prior to carbonization), or synthetically using known processes (e.g., pyrolysis of polystyrene beads). In other embodiments, the active particles 40.sub.1-40.sub.P may comprise activated alumina (aluminum oxide), silica gel, soda ash, aluminum trihydrate, baking soda, cinoxate (p-methoxy-2-ethoxyethyl ester cinnamic acid), zinc oxide, zeolites, titanium dioxide, or any other suitable material.
[0100] The active particles 40.sub.1-40.sub.P may be incorporated into the fabric 30 using any suitable process. For example, in some embodiments, the active particles 40.sub.1-40.sub.P may be joined to the fibrous base substance 29 of the fabric 30 using: an air dispersion process in which the active particles are entrained in a gaseous carrier onto the fibrous base substance 29 of the fabric 30 where they are fixed; a padding process in which the fibrous base substance 29 of the fabric 30 is passed through a bath of the active particles; a liquid suspension or mixture of a binder and the active particles applied to the fibrous base substance 29 of the fabric 30; or a xerographic process using electrostatic or magnetic attraction to transfer a toner formulation including the active particles towards the fibrous base substance 29 of the fabric 30. In some cases, a protective substance may be provided onto the active particles 40.sub.1-40.sub.P to protect these active particles during manufacturing of the fabric 30 and subsequently removed. Examples of such processes are described in U.S. Pat. No. 6,998,155, U.S. Patent Application Publication 2008/0121141 and U.S. Pat. No. 7,247,374, which are incorporated by reference herein.
[0101] Examples of materials that can be used for the fabric 30 including the active particles 40.sub.1-40.sub.P may be commercially obtained from Cocona Inc., Boulder, Colo.
[0102] In addition to its quick-drying fabric 30 which enhances moisture management, in this embodiment, the shirt 10 has functional features to interact with the protective athletic equipment 12, protect the player, and/or otherwise enhance the player's comfort and performance.
[0103] For instance, in this embodiment, the shirt 10 comprises grippers 44.sub.1-44.sub.3 for engaging and gripping the protective athletic equipment 12 to help hold it in place. In this example, the grippers 44.sub.1, 44.sub.2 are located on the sleeves 24.sub.1, 24.sub.2 to engage the elbow pads 15.sub.1, 15.sub.2, while the gripper 44.sub.3 is located on the torso portion 14 to engage the shoulder pads 13.
[0104] The grippers 44.sub.1-44.sub.3 can grip the protective athletic equipment 12 in any suitable way to help hold it in place. In this embodiment, each of the grippers 44.sub.1-44.sub.3 is a frictional gripper that helps to hold the protective athletic equipment 12 in place by friction. That is, a frictional force exerted by a gripper 44.sub.x on an underside of the protective athletic equipment 12 is greater than a frictional force exerted by the fabric 30 on the underside of the protective athletic equipment 12 (i.e., a coefficient of friction between the gripper 44.sub.x and the underside of the protective athletic equipment 12 is greater than a coefficient of friction between the fabric 30 and the underside of the protective athletic equipment 12).
[0105] The grippers 44.sub.1-44.sub.3 may comprise any suitable material to exert sufficient friction. For example, in this embodiment, each of the grippers 44.sub.1-44.sub.3 comprises a tackifying material 43 such as a thermoplastic elastomer (e.g., Santoprene), polyurethane (thermoplastic or thermoset), polyvinyl chloride (e.g., Plastisol), silicone, or any other suitable material providing tackiness. More particularly, in this example, each of the grippers 44.sub.1-44.sub.3 includes frictional gripping members 45.sub.1-45.sub.B which are made of the tackyfing material 43.
[0106] Any other suitable material providing a high coefficient of friction may be used in other embodiments. For instance, in some embodiments, each of the grippers 44.sub.1-44.sub.3 may comprise hooks or loops of a hook-and-loop fastener (e.g., Velcro)) to engage the underside of the protective athletic equipment 12. In some cases, the underside of the protective athletic equipment 12 may include complementary loops or hooks of the hook-and-loop fastener to engage the hooks or loops of the grippers 44.sub.1-44.sub.3. In other cases, the underside of the protective athletic equipment 12 may not include complementary loops or hooks, in which case the grippers 44.sub.1-44.sub.3 may have hooks that anchor themselves in a material (e.g., fabric) on the underside of the protective athletic equipment 12.
[0107] The grippers 44.sub.1-44.sub.3 may be provided in the shirt 10 in any suitable way. For instance, in this embodiment, the grippers 44.sub.1-44.sub.3 may be printed (e.g., screen-printed) onto the fabric 30. In other embodiments, the grippers 44.sub.1-44.sub.3 may be adhesively bonded to the fabric 30, stitched to the fabric 30, or provided using any other suitable process.
[0108] In this embodiment, the shirt 10 comprises a protector 48 for protecting a body part of the player. In this example, the protector 48 comprises a neck guard at a collar 39 of the shirt 10 to protect the player's neck against cuts from and possibly other impacts with skates, hockey sticks, pucks, or other objects.
[0109] More particularly, in this embodiment, with additional reference to
[0110] Also, in this embodiment, the neck guard 48 comprises padding 51 to provide padded protection and comfort to the player. The pad 51 may comprise foam, such as ethylene vinyl acetate (EVA) foam, expanded polypropylene (EPP) foam, expanded polyethylene (EPE) foam (e.g., low-density polyethylene (LDPE) foam), vinyl nitrile (VN) foam, polyurethane foam, or any other suitable foam, and/or may comprise any other shock-absorbing material (e.g., a gel).
[0111] Furthermore, in this embodiment, the neck guard 48 comprises an outer covering 52 disposed over the cut-resistant material 50 and the padding 51 and forming an external surface of the neck guard 48. In this example, the outer covering 52 is a fabric. More particularly, in this example, the fabric 52 is a quick-drying fabric as described above in respect of the fabric 30.
[0112] The neck guard 48 is configured to receive the player's neck when the player puts on the shirt 10 and to be removed from the player's neck when the player takes off the shirt 10. In this embodiment, the neck guard 48 is openable to receive and be removed from the player's neck. More particularly, in this example, the neck guard 48 includes a closure 53 that is selectively openable and closable to allow the player's neck to be received by and removed from the neck guard 48. In this case, the closure 53 includes a fastener (e.g., a hook-and-loop fastener, a button, etc.) to keep it closed, and cooperates with a zipper 27 extending in the back of the shirt 10. In other examples, the neck guard 48 may be stretchable to permit it to be stretched over the player's head and then closed by contracting around the player's neck when the player puts on the shirt 10.
[0113] Although it comprises a neck guard in this embodiment, the protector 48 may be provided to protect another body part of the player in other embodiments (e.g., a pad secured to the fabric 30 to protect a chest, back, shoulder, elbow, or other body part of the player).
[0114] While the shirt 10 is constructed in a particular way in this embodiment, the shirt may be constructed in various other ways in other embodiments.
[0115] For example, in some embodiments, as shown in
[0116] For instance, in this embodiment, the area 60.sub.1 of the shirt 10 is an area of the torso portion 14 of the shirt 10 that is disposed to overlie a front region of the player's torso and be covered the shoulder pads 13, the area 60.sub.2 of the shirt 10 is an area of the torso portion 14 of the shirt 10 that is disposed to overlie a back region of the player's torso and be covered the shoulder pads 13, the areas 60.sub.3, 60.sub.4 of the shirt 10 are areas of the torso portion 14 of the shirt 10 that are disposed to overlie lateral regions of the player's torso and not be covered by the shoulder pads 13, the areas 60.sub.5, 60.sub.6 of the shirt 10 are areas of the sleeves 24.sub.1, 24.sub.2 of the shirt 10 that are disposed to overlie elbow regions of the player's arms and be covered by the elbow pads 15.sub.1, 15.sub.2, and the areas 60.sub.7, 60.sub.8 of the shirt 10 are areas of the sleeves 24.sub.1, 24.sub.2 of the shirt 10 that are disposed to overlie upper arm regions of the player's arms and not be covered by the elbow pads 15.sub.1, 15.sub.2.
[0117] As an example, the drying rate of the areas 60.sub.1, 60.sub.2, 60.sub.3, 60.sub.4 of the shirt 10, which overly regions of the player's torso that may generate more sweat, may be greater than the drying rate of the areas 60.sub.5, 60.sub.6, 60.sub.7, 60.sub.8 of the shirt 10, which overly regions of the player's arms that may generate less sweat. As another example, the drying rate of the areas 60.sub.1, 60.sub.2 of the shirt 10, which overly regions of the player's torso that are beneath the shoulder pads 13, may be greater than the drying rate of the areas 60.sub.3, 60.sub.4 of the shirt 10, which overly regions of the player's torso that are not beneath the shoulder pads 13. As yet another example, the drying rate of the area 60.sub.2 of the shirt 10, which overlies the back region of the player's torso that may generate more sweat, may be greater than the drying rate of the area 60.sub.1 of the shirt 10, which overlies the front region of the player's torso that may generate less sweat, even though both of the areas 60.sub.1, 60.sub.2 of the shirt 10 are covered by the shoulder pads 13. As yet another example, the drying rate of the areas 60.sub.5, 60.sub.6 of the shirt 10, which overly regions of the player's arms that are covered by the elbow pads 15.sub.1, 15.sub.2, may be greater than the drying rate of the areas 60.sub.7, 60.sub.8 of the shirt 10, which overly regions of the player's arms that are not covered by the elbow pads 15.sub.1, 15.sub.2.
[0118] For example, in some embodiments, a ratio of (i) the drying rate of a given area 60.sub.i of the shirt 10 over (ii) the drying rate of another area 60.sub.j the shirt 10 may be at least 1.1, in some cases at least 1.2, in some cases at least 1.3, in some cases at least 1.4, in some cases at least 1.5, and in some cases even more (e.g., 2 or more). The difference between the drying rate of the area 60.sub.i of the shirt 10 and the drying rate of the area 60.sub.j of the shirt 10 may take on any other suitable value in other embodiments.
[0119] The variation of the drying rate over the areas 60.sub.1-60.sub.D of the shirt 10 can be implemented in any suitable manner. In this embodiment, this may be achieved by varying a concentration or loading of the active particles 40.sub.1-40.sub.P of the fabric 30 over the areas 60.sub.1-60.sub.D of the shirt 10. The concentration or loading of the active particles 40.sub.1-40.sub.P of the fabric 30 in a given area 60.sub.i of the shirt 10 may be greater than the concentration or loading of the active particles 40.sub.1-40.sub.P of the fabric 30 in another area 60.sub.j of the shirt 10 such that the drying rate of the area 60.sub.i of the shirt is greater than the drying rate of the area 60.sub.j of the shirt 10. The concentration or loading of the active particles 40.sub.1-40.sub.P of the fabric 30 in a particular area 60.sub.x of the shirt 10 can be measured as a weight percent of the active particles 40.sub.1-40.sub.P in the area 60.sub.x of the shirt 10, i.e., a weight of the active particles 40.sub.1-40.sub.P in the area 60.sub.x of the shirt 10 divided by a total weight of the area 60.sub.x of the shirt 10 and multiplied by one hundred. For example, in some embodiments, a ratio of (i) the concentration or loading of the active particles 40.sub.1-40.sub.P of the fabric 30 in the given area 60.sub.i of the shirt 10 over (ii) the concentration or loading of the active particles 40.sub.1-40.sub.P of the fabric 30 in the other area 60.sub.j of the shirt 10 may be at least 1.1, in some cases at least 1.2, in some cases at least 1.5, in some cases at least 2, in some cases at least 4, and in some cases even more (e.g., 8 or more). In some examples of implementation, an area 60.sub.x of the shirt 10 may be free of active particles, i.e., there is no active particle in the area 60.sub.x of the shirt 10, such that the concentration or loading of the active particles 40.sub.1-40.sub.P of the fabric 30 in the area 60.sub.x of the shirt 10 is substantially zero. The variation of the drying rate over the areas 60.sub.1-60.sub.D of the shirt 10 can be implemented in other ways in other embodiments (e.g., by varying a yarn size or fabric weight in different areas).
[0120] To further enhance moisture management, in some embodiments, with additional reference to
[0121] In this embodiment, the cooling material 65 is a fabric. The cooling fabric 65 comprises a fibrous base substance 37 including fibers 33.sub.1-33.sub.R, which may include any suitable natural or synthetic fibers (e.g., polyester, nylon, spandex (elastane), or other fibers, or blends of these fibers). In this example, the cooling fabric 65 is a woven or knit fabric.
[0122] The cooling effect provided by the cooling fabric 65 may be implemented in any suitable way. In this embodiment, the cooling fabric 65 comprises active elements 70.sub.1-70.sub.V to generate the cooling effect. More particularly, in this embodiment, the active elements 70.sub.1-70.sub.V are connected to the fibrous base substance 37. For example, in some embodiments, the cooling fabric 65 may be configured to cool down when absorbing moisture as the player sweats, i.e., a moisture-activated cooling fabric. For instance, the active elements 70.sub.1-70.sub.V may be swellable elements configured to swell when absorbing moisture to create the cooling effect. Examples of materials that can be used for the cooling fabric 65 that is moisture-activated are fabrics including Nexar polymers which may be commercially obtained from Kraton Performance Polymers Inc., Houston, Tex.
[0123] As another example, in some embodiments, the cooling fabric 65 may be configured to cool down when absorbing heat from the player's body, i.e., a heat-activated cooling fabric. For instance, the active elements 70.sub.1-70.sub.V may be phase-change material (PCM) elements (e.g., microencapsulated PCM elements) configured to change phase when absorbing heat to create the cooling effect. Examples of materials that can be used for the cooling fabric 65 that is heat-activated are fabrics including Thermocules PCM elements which may be commercially obtained from Outlast Technologies LLC, Boulder, Colo. In other embodiments, the fibers 33.sub.1-33.sub.R of the cooling fabric 65 may themselves be the active elements 70.sub.1-70.sub.V that generate the cooling effect on their own, without having distinct active elements connected to the fibers 33.sub.1-33.sub.R of the fibrous base substance 37. For instance, the fibers 33.sub.1-33.sub.R of the cooling fabric 65 may be configured to cool down when absorbing and trapping moisture inside them as the player sweats. Examples of materials that can be used for this purpose may be commercially obtained from CoolCore, Portsmouth, N.H. Other examples of materials that can be used for the cooling fabric 65 may include IceFil by Ventex, Luxicool, Cool Jade, Advansa's Thermo Cool, and HeiQ's Adaptive.
[0124] The quick-drying fabric 30 and the cooling fabric 65 may be arranged in any suitable manner in the shirt 10. For example, in this embodiment, a quantity of the quick-drying fabric 30 in the shirt 10 is greater than a quantity of the cooling fabric 65 in the shirt 10. More particularly, in this embodiment, the quick-drying fabric 30 is present in a bulk of the shirt 10, while the cooling fabric 65 is present only in a limited area of the shirt 10 where the cooling effect may be better perceived by the player. Thus, in this embodiment, the cooling fabric 65 is present in a quick-cooling spot of the player's body, i.e., a spot of the player's body that is more efficient at cooling. The quick-cooling spot includes a pulse point, i.e., an area where the player's pulse can be felt since blood vessels are closer to his/her skin's surface, meaning that blood and body temperature can be more easily cooled. In this example, the cooling fabric 65 is disposed in the collar 39 of the shirt 10 since the cooling effect at the player's neck may be well perceived by the player. In cases where the shirt 10 includes the neck guard 48 as discussed previously, the outer covering 52 of the neck guard 48 may comprise the cooling fabric 65. In other examples, the cooling fabric 65 may be disposed in other quick-cooling spots of the player's body (e.g., a crook of the elbow, a wrist, a forehead, an inner thigh, a bend of the knee, or an ankle).
[0125] In some embodiments, the fabric 30, which makes up at least part of the torso portion 14 and the sleeves 24.sub.1, 24.sub.2 of the shirt 10, may be a quick-drying and cooling fabric. That is, the fabric 30 may be configured such that (1) its drying rate is relatively high and (2) it provides a cooling effect perceivable by the player. For example, in some embodiments, as shown in
[0126] In some embodiments, as shown in
[0127] More particularly, in this embodiment, each of the vents 66.sub.1-66.sub.A comprises a mesh material 63 (i.e., a material having an open texture) for ventilation. In this example, the vents 66.sub.1-66.sub.A are respectively located in underarm, back, neck, lateral sides, and arm areas of the shirt 10. The vents 66.sub.1-66.sub.A may be disposed in any other suitable manner in other examples. The vents 66.sub.1-66.sub.A may be implemented in various other ways in other embodiments (e.g., openings).
[0128] In some embodiments, the shirt 10 may comprise an indicator 71 to indicate a current quick-drying effectiveness of the quick-drying fabric 30. This quick-drying effectiveness indicator 71 may be useful in cases where the effectiveness of the fabric 30 at quickly-drying itself can decrease (e.g., after the shirt 10 has been repeatedly used or has been washed with a detergent) in order to allow the player to know when the shirt 10 may no longer work as desired.
[0129] While in embodiments considered above it is a fabric making up a bulk of the shirt 10, the quick-drying material 30 may be another type of material making up one or more smaller parts of the shirt 10 in other embodiments. For example, in some embodiments, as shown in
[0130] In some embodiments, the quick-drying material 30 may be anti-microbial. For instance, in some embodiments in which it is a fabric, the quick-drying material 30 may be treated (e.g., via a pad bath or exhaust process) or may have yarn-based anti-microbial or anti-odor technology.
[0131] Although in this embodiment the baselayer garment 10 is an undershirt, the baselayer garment 10 may be any other baselayer garment in other embodiments. For example, in some embodiments, the baselayer garment 10 may be underpants (e.g., shorts or a cup supporter) configured to be worn under protective pants (e.g., protective shorts), a sock configured to be worn under a shin guard, a compression sleeve (e.g., arm or shin sleeve) configured to be worn under an arm pad (e.g., an elbow pad) or a leg pad, or a head cap configured to be worn under a helmet.
[0132] While in this embodiment the athletic garment 10 is configured to be worn under the protective athletic equipment 12, the athletic garment 10 may be configured to be worn over the protective athletic equipment 12 in other embodiments. For example, in some embodiments, the athletic garment 10 may be a jersey (e.g., a team jersey) configured to be worn over the protective athletic equipment 12.
2. Protective Athletic Equipment
[0133] The shoulder pads 13 protect various regions of the player's upper body. As shown in
[0134] The shoulder pads 13 comprise an inner surface 23 for facing towards the player and an outer surface 25 for facing away from the player. In this embodiment in which the shoulder pads 13 are to be worn over the shirt 10, the inner surface 23 of the shoulder pads 13 is configured to contact the outer surface 19 of the shirt 10.
[0135] The shoulder pads 13 comprise a front 54, a back 55, left and right shoulder arches 56.sub.1, 56.sub.2, and left and right shoulder protectors 57.sub.1, 57.sub.2. The front 54, the back 55, and the shoulder arches 56.sub.1, 56.sub.2 define a neck opening 58 for receiving the player's neck. In this embodiment, the shoulder pads 13 also comprise left and right upper arm protectors 59.sub.1, 59.sub.2.
[0136] The front 54 of the shoulder pads 13 is configured to cover at least part of the front side FS of the player's thorax. In this embodiment, the front 54 of the shoulder pads 13 comprises left and right pectoral portions 72.sub.1, 72.sub.2 for covering the left and right pectoral regions LPR, RPR of the player, a sternum portion 73 for covering the sternum region SR of the player, and a top edge 74 delimiting the neck opening 58.
[0137] In this embodiment, with additional reference to
[0138] The outer covering 77 of the front 54 of the shoulder pads 13 faces away from the player's body. The outer covering 77 comprises a material 78 making up at least part of the outer covering 77. That is, the outer covering 77 is at least partly (i.e., partly or entirely) made of the material 78. For instance, in some embodiments, the material 78 may be a flexible material (e.g., a woven fabric, a polyurethane or other elastomeric layer, etc.). In other embodiments, the material 78 may be a rigid material (e.g., polycarbonate, high-density polyethylene (HDPE), polypropylene, etc.) that forms a rigid shell.
[0139] The inner liner 76 of the front 54 of the shoulder pads 13 faces the player's body. More particularly, in this embodiment, the inner liner 76 faces and engages the shirt 10. The inner liner 76 comprises a material 80 making up at least part of the inner liner 76. That is, the inner liner 76 is at least partly (i.e., partly or entirely) made of the material 80. In this embodiment, the inner liner 76 is at least mainly (i.e., mainly or entirely) made of the material 80.
[0140] In this embodiment, with additional reference to
[0141] For example, in this embodiment, the fibers 82.sub.1-82.sub.R of the fabric 80 of the inner liner 76 include polyester fibers. For instance, the fabric 80 may comprise different types of polyester fibers (e.g., the fabric 80 may comprise 51% 75D/48F textured polyester and 49% 50D/72F polyester and weigh 120 g/m.sup.2). The fabric 80 may have any other suitable composition in other embodiments.
[0142] The fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 13 is configured taking into account movements of the player. In this example, the fabric 80 is also configured taking into account an interface between the shirt 10 and the shoulder pads 13. For instance, in this embodiment, the fabric 80 has mechanical properties to resist tearing or other excessive damage due to movements of the player and/or friction or other contact between the shirt 10 and the shoulder pads 13.
[0143] In this embodiment, the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 13 is a quick-drying material, i.e., a material exhibiting a drying rate which is relatively high, to quickly evaporate moisture as the player sweats. In this example, at least some liquid moisture evaporated by the fabric 80 may have been transported to the inner liner 76 by the shirt 10 which wicked this liquid moisture away from the wearer's body. For example, in some embodiments, the drying rate of the fabric 80 may be at least 2.1 ml/hr, in some cases at least 2.3, in some cases at least 2.5, and in some cases even more, according to AATCC Test Method 201 of the American Association of Textile Chemists and Colorists (AATCC). Alternatively or additionally, in some embodiments, the drying rate of the fabric 80 may be at least 15 ml/hr, in some cases at least 20 ml/hr, in some cases at least 25 ml/hr, and in some cases even more, according to AATCC Test Method 200 of the AATCC. The drying rate of the fabric 80 may have any other suitable value in other embodiments.
[0144] More particularly, in this embodiment, to facilitate moisture evaporation, the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 13 is configured to (1) spread moisture over a large surface area and (2) harness heat generated by the player's body to vaporize liquid moisture.
[0145] For example, in some embodiments, a surface area of the fabric 80 may be at least 300 cm.sup.2 per square centimeter of fabric, in some cases at least 400 cm.sup.2 per square centimeter of fabric, in some cases at least 500 cm.sup.2 per square centimeter of fabric, in some cases at least 600 cm.sup.2 per square centimeter of fabric, and in some cases even more. Alternatively or additionally, in some embodiments, a surface area of a constituent of the fabric 80 may be at least 200 m.sup.2 per gram of the constituent, in some cases at least 400 m.sup.2 per gram of the constituent, in some cases at least 600 m.sup.2 per gram of the constituent, in some cases at least 800 m.sup.2 per gram of the constituent, in some cases at least 1000 m.sup.2 per gram of the constituent and in some cases even more. The surface area of the constituent of the fabric 80 may have any other suitable value in other embodiments.
[0146] To harness heat generated by the player's body to vaporize moisture, a constituent of the fabric 80 captures this heat to raise its temperature and cause vaporization of liquid moisture in contact with it. For example, in some embodiments, a specific heat capacity of a constituent of the fabric 80 (i.e., an amount of heat required to increase the temperature of a unit mass of the constituent of the fabric 80 by one degree) may be relatively low. For instance, in some embodiments, the specific heat capacity of the constituent of the fabric 80 may be less than polyester's specific heat capacity. The specific heat capacity of the constituent of the fabric 80 may have any other suitable value in other embodiments. Additionally or alternatively, in some embodiments, a molar absorptivity at an infrared wavelength of a constituent of the fabric 80 (i.e., a measurement of how strongly a chemical species of the constituent of the fabric 80 absorbs electromagnetic radiation at the infrared wavelength) may be relatively high. For instance, in some embodiments, the molar absorptivity at an infrared wavelength of the constituent of the fabric 80 may be greater than polyester's molar absorptivity at that infrared wavelength. The molar absorptivity at the infrared wavelength of the constituent of the fabric 80 may have any other suitable value in other embodiments.
[0147] Also, in some embodiments, a constituent of the fabric 80 may be configured to manifest an exothermic reaction releasing heat to accelerate the drying process. That is, a constituent of the fabric 80 may be configured to exothermically react (i.e., produce heat when reacting) with liquid moisture. The exothermic reaction may be chemical and/or physical. For example, in some embodiments, the exothermic reaction manifested by the constituent of the fabric 80 may be adsorption of liquid moisture by the constituent of the fabric 80, such that heat is released when the liquid moisture is adsorbed by the constituent of the fabric 80.
[0148] In this embodiment, the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 13 comprises active elements 84.sub.1-84.sub.E to manage moisture as the player sweats, including to enhance evaporation of liquid moisture in the fabric 80. The active elements 84.sub.1-84.sub.E are active in that they have a property allowing them to induce a chemical and/or physical reaction in response to a stimulus at their surface. In this example, this reaction induced by the active elements 84.sub.1-84.sub.E helps accelerate the drying process of the fabric 80. The fabric 80 thus dries faster than if the active elements 84.sub.1-84.sub.E were omitted but the fabric 80 was otherwise identical (i.e., dries faster than a comparative fabric identical to the fabric 80 but without the active elements 84.sub.1-84.sub.E).
[0149] In this example of implementation, the active elements 84.sub.1-84.sub.E are connected to the fibers 82.sub.1-82.sub.R of the fibrous base substance 81. In other examples of implementation, the fibers 82.sub.1-82.sub.R of the fabric 80 may themselves be the active elements 84.sub.1-84.sub.E that enhance the drying process of the fabric 80 on their own, without having distinct active elements connected to the fibers 82.sub.1-82.sub.R.
[0150] More particularly, in this embodiment, the active elements 84.sub.1-84.sub.E are active particles distributed within the fabric 80. In this example, the active particles 84.sub.1-84.sub.E have an adsorptive property that causes them to adsorb liquid moisture as the player sweats. This reaction, i.e., adsorption, caused by the active particles 84.sub.1-84.sub.E helps evaporating the liquid moisture.
[0151] With additional reference to
[0152] Because of their pores 85.sub.1-85.sub.L, the active particles 84.sub.1-84.sub.E have a surface area which is very large, thereby vastly spreading the liquid moisture to aid evaporating it. For example, in some embodiments, the surface area of the active particles 84.sub.1-84.sub.E may be such that the surface area of the fabric 80 is at least 300 cm.sup.2 per square centimeter of fabric, in some cases at least 400 cm.sup.2 per square centimeter of fabric, in some cases at least 500 cm.sup.2 per square centimeter of fabric, in some cases at least 600 cm.sup.2 per square centimeter of fabric, and in some cases even more. Alternatively or additionally, in some embodiments, the surface area of the active particles 84.sub.1-84.sub.E may be at least 200 m.sup.2 per gram of active particle, in some cases at least 400 m.sup.2 per gram of active particle, in some cases at least 600 m.sup.2 per gram of active particle, in some cases at least 800 m.sup.2 per gram of active particle, in some cases at least 1000 m.sup.2 per gram of active particle and in some cases even more. The surface area of the active particles 84.sub.1-84.sub.E may have any other suitable value in other embodiments.
[0153] Also, in this embodiment, the active particles 84.sub.1-84.sub.E use heat generated by the player's body to vaporize moisture. For example, in some embodiments, a specific heat capacity of the active particles 84.sub.1-84.sub.E may be relatively low. For instance, in some embodiments, the specific heat capacity of the active particles 84.sub.1-84.sub.E may be less than a specific heat capacity of the fibrous base substance 81 of the fabric 80. Thus, in this example, the specific heat capacity of the active particles 84.sub.1-84.sub.E may be less than polyester's specific heat capacity. The specific heat capacity of the active particles 84.sub.1-84.sub.E may have any other suitable value in other embodiments. Additionally or alternatively, in some embodiments, a molar absorptivity at an infrared wavelength of the active particles 84.sub.1-84.sub.E may be relatively high. For instance, in some embodiments, the molar absorptivity at an infrared wavelength of the active particles 84.sub.1-84.sub.E may be greater than a molar absorptivity at that infrared wavelength of the fibrous base substance 81 of the fabric 80. For instance, in some embodiments, the molar absorptivity at an infrared wavelength of the active particles 84.sub.1-84.sub.E may be greater than polyester's molar absorptivity at that infrared wavelength. The molar absorptivity at the infrared wavelength of the active particles 84.sub.1-84.sub.E may have any other suitable value in other embodiments.
[0154] Furthermore, the adsorption of liquid moisture by the active particles 84.sub.1-84.sub.E is an exothermic reaction releasing heat that helps to accelerate the drying process.
[0155] The active particles 84.sub.1-84.sub.E may be implemented in any suitable way. In this embodiment, the active particles 84.sub.1-84.sub.E comprise activated carbon. The activated carbon may be produced in various known ways. For instance, the activated carbon may be produced from carbonaceous materials such as wood, nutshells, coconut husk, coir, peat, lignite, coal, or other carbonaceous substances using known processes (e.g., physical reactivation using hot gases which involves carbonization and/or oxidation, or chemical activation using chemicals on raw material prior to carbonization), or synthetically using known processes (e.g., pyrolysis of polystyrene beads). In other embodiments, the active particles 84.sub.1-84.sub.E may comprise activated alumina (aluminum oxide), silica gel, soda ash, aluminum trihydrate, baking soda, cinoxate (p-methoxy-2-ethoxyethyl ester cinnamic acid), zinc oxide, zeolites, titanium dioxide, or any other suitable material.
[0156] The active particles 84.sub.1-84.sub.E may be incorporated into the fabric 80 using any suitable process. For example, in some embodiments, the active particles 84.sub.1-84.sub.E may be joined to the fibrous base substance 81 of the fabric 80 using: an air dispersion process in which the active particles are entrained in a gaseous carrier onto the fibrous base substance 81 of the fabric 80 where they are fixed; a padding process in which the fibrous base substance 81 of the fabric 80 is passed through a bath of the active particles; a liquid suspension or mixture of a binder and the active particles applied to the fibrous base substance 81 of the fabric 80; or a xerographic process using electrostatic or magnetic attraction to transfer a toner formulation including the active particles towards the fibrous base substance 81 of the fabric 80. In some cases, a protective substance may be provided onto the active particles 84.sub.1-84.sub.E to protect these active particles during manufacturing of the fabric 80 and subsequently removed. Examples of such processes are described in U.S. Pat. No. 6,998,155, U.S. Patent Application Publication 2008/0121141 and U.S. Pat. No. 7,247,374, which are incorporated by reference herein.
[0157] Examples of materials that can be used for the fabric 80 including the active particles 84.sub.1-84.sub.E may be commercially obtained from Cocona Inc., Boulder, Colo.
[0158] The back 55 of the shoulder pads 13 is configured to cover at least part of the back side BS of the player's thorax. In this embodiment, the back 55 of the shoulder pads 13 comprises a spinal portion 85 for covering the thoracic spinal region TSR of the player, left and right trapezius portions 88.sub.1, 88.sub.2 for covering the left and right trapezius regions LTR, RTR of the player, left and right latissimus dorsi portions 89.sub.1, 89.sub.2 for covering the left and right latissimus dorsi regions LLR, RLR of the player, and a top edge 89 delimiting the neck opening 58.
[0159] In this embodiment, with additional reference to
[0160] The left and right shoulder arches 56.sub.1, 56.sub.2 are configured to respectively arch over the left and right shoulders of the player and interconnect the front 54 and the back 55 of the shoulder pads 13.
[0161] In this embodiment, with additional reference to
[0162] The shoulder protectors 57.sub.1, 57.sub.2 are configured to respectively cover at least part of the left and right shoulders of the player. In this embodiment, each of the shoulder protectors 57.sub.1, 57.sub.2 comprises an acromioclavicular joint portion and a deltoid portion for respectively covering at least part of the acromioclavicular joint region ACR and the deltoid region DR of the shoulder it protects.
[0163] Each shoulder protector 57.sub.x is connected to at least one of the front 54, the back 55, and a given one of the shoulder arches 56.sub.1, 56.sub.2. In this embodiment, the shoulder protector 57.sub.x, is connected to the shoulder arch 56.sub.x arching over the shoulder that it protects. Also, in this embodiment, the shoulder protector 57.sub.x is connected to the arm protector 59.sub.x which is on the arm extending from the shoulder it protects. The shoulder protector 57.sub.x may be directly connected (e.g., sewed) to the shoulder arch 56 and/or the arm protector 59.sub.x or may be indirectly connected (e.g., via one or more straps sewed) to the shoulder arch 56.sub.x and/or the arm protector 59.sub.x.
[0164] In this embodiment, with additional reference to
[0165] The upper arm protectors 59.sub.1, 59.sub.2 are configured to cover at least part of the left and right arms of the player. Each of the upper arm protectors 59.sub.1, 59.sub.2 comprises an outer arm portion for overlying an outer region of the arm it protects and a strap for retaining itself on the arm.
[0166] In this embodiment, with additional reference to
[0167] While the shoulder pads 30 are constructed in a particular way in this embodiment, the shoulder pads 30 may be constructed in various other ways in other embodiments.
[0168] For example, in some embodiments, as shown in
[0169] In this embodiment, the area 160.sub.1 of the shoulder pads 13 is an area of the front 54 of the shoulder pads 13 that is disposed to overlie a chest region of the player's torso, the area 160.sub.2 of the shoulder pads 13 is an area of the back of the shoulder pads 13 that is disposed to overlie a back region of the player's torso, and the areas 160.sub.3, 160.sub.4 of the shoulder pads 13 are areas of the shoulder protectors 57.sub.1, 57.sub.2 that are disposed to overlie shoulder regions of the player's torso.
[0170] As an example, the drying rate of the areas 160.sub.1, 160.sub.2 of the shoulder pads 13, which are overlying regions of the player's body which may generate more sweat, may be greater than the drying rate of the areas 160.sub.3, 160.sub.4 of the shoulder pads 13, which are overlying regions of the player's body which may generate less sweat. As another example, the drying rate of the area 160.sub.2 of the back 55 of the shoulder pads 13, which overlies the back region of the player's body, may be greater than the drying rate of the area 160.sub.1 of the front 54 of the shoulder pads 13, which overlies the front region of the player's body that may generate less sweat than the back region of the player's body.
[0171] For example, in some embodiments, a ratio of (i) the drying rate of a given area 160.sub.i of the shoulder pads 13 over (ii) the drying rate of another area 160.sub.j of the shoulder pads 13 may be at least 1.1, in some cases at least 1.2, in some cases at least 1.3, in some cases at least 1.4, in some cases at least 1.5, and in some cases even more (e.g., 2 or more). The difference between the drying rate of respective ones of the areas 160.sub.1-160.sub.H of the shoulder pads 13 may take on any other suitable value in other embodiments.
[0172] The variation of the drying rate over the areas 160.sub.1-160.sub.H of the shoulder pads 13 can be implemented in any suitable manner. In this embodiment, this may be achieved by varying a concentration or loading of active particles of a fabric, such as the active particles 84.sub.1-84.sub.E of the fabric 80 of the front 54 of the shoulder pads 13 and similar active particles of the fabric of other parts of the shoulder pads 13, over the areas 160.sub.1-160.sub.H of the shoulder pads 13. The concentration or loading of the active particles of the fabric in a given area 160.sub.i of the shoulder pads may be greater than the concentration or loading of the active particles of the fabric in another area 160.sub.j of the shoulder pads 13 such that the drying rate of the area 160 of the shoulder pads 13 is greater than the drying rate of the area 160.sub.j of the shoulder pads 13. For example, in some embodiments, a ratio of (i) the concentration or loading of the active particles of the fabric in the given area 160.sub.i of the shoulder pads 13 over (ii) the concentration or loading of the active particles of the fabric in the other area 160.sub.j of the shoulder pads 13 may be at least 1.1, in some cases at least 1.2, in some cases at least 1.5, in some cases at least 2, in some cases at least 4, and in some cases even more (e.g., 8 or more). The concentration or loading of the active particles of the fabric in a particular area 160.sub.x of the shoulder pads 13 can be measured as a weight percent of the active particles in that particular area 160.sub.x of the shoulder pads 13, i.e., a weight of the active particles in the area 160.sub.x of the shoulder pads 13 divided by a total weight of the fabric of the area 160.sub.x of the shoulder pads 13 and multiplied by one hundred. In some examples of implementation, an area 160.sub.x of the shoulder pads 13 may be free of active particles, i.e., there is no active particle in the area 160.sub.x of the shoulder pads 13, such that the concentration or loading of the active particles of the fabric in the area 160.sub.x of the shoulder pads 13 is substantially zero. The variation of the drying rate over the areas 160.sub.1-160.sub.H of the shoulder pads 13 can be implemented in other ways in other embodiments (e.g., by varying a yarn size or fabric weight in different areas).
[0173] In some embodiments, the drying rate of a given area of the shirt 10 may be different from the drying rate of an overlapping area of the shoulder pads 13 which overlaps the given area of the shirt 10. For example, in some embodiments, the drying rate of the given area of the shirt 10 may be greater than the drying rate of the overlapping area of the shoulder pads 13 since the shirt 10 is more directly exposed to the player's sweat. For instance, in this example of implementation, the concentration or loading of the active particles of the fabric in the given area of the shirt 10 may be greater than the concentration or loading of the active particles of the fabric in the overlapping area of the shoulder pads 13 such that the drying rate of the given area of the shirt 10 is greater than the drying rate of the overlapping area of the shoulder pads 13. For example, in some embodiments, a ratio of (i) the concentration or loading of the active particles of the fabric in the given area of the shirt 10 over (ii) the concentration or loading of the active particles of the fabric in the overlapping area of the shoulder pads 13 may be at least 1.1, in some cases at least 1.2, in some cases at least 1.5, in some cases at least 2, in some cases at least 4, and in some cases even more (e.g., 8 or more).
[0174] To further enhance moisture management, in some embodiments, with additional reference to
[0175] In this embodiment, the cooling material 165 is a fabric. The cooling fabric 165 comprises a fibrous base substance 137 including fibers 133.sub.1-133.sub.K, which may include any suitable natural or synthetic fibers (e.g., polyester, nylon, spandex (elastane), or other fibers, or blends of these fibers). In this example, the cooling fabric 165 is a woven fabric.
[0176] The cooling effect provided by the cooling fabric 165 may be implemented in any suitable way. In this embodiment, the cooling fabric 165 comprises active elements 170.sub.1-170.sub.C to generate the cooling effect. More particularly, in this embodiment, the active elements 170.sub.1-170.sub.C are connected to the fibers 133.sub.1-133.sub.K of the fibrous base substance 137. For example, in some embodiments, the cooling fabric 165 may be configured to cool down when absorbing moisture as the player sweats, i.e., a moisture-activated cooling fabric. For instance, the active elements 170.sub.1-170.sub.C may be swellable elements configured to swell when absorbing moisture to create the cooling effect. Examples of materials that can be used for the cooling fabric 165 that is moisture-activated are fabrics including Nexar polymers which may be commercially obtained from Kraton Performance Polymers Inc., Houston, Tex. As another example, in some embodiments, the cooling fabric 165 may be configured to cool down when absorbing heat from the player's body, i.e., a heat-activated cooling fabric. For instance, the active elements 170.sub.1-170.sub.C may be phase-change material (PCM) elements (e.g., microencapsulated PCM elements) configured to change phase when absorbing heat to create the cooling effect. Examples of materials that can be used for the cooling fabric 165 that is heat-activated are fabrics including Thermocules PCM elements which may be commercially obtained from Outlast Technologies LLC, Boulder, Colo. In other embodiments, the fibers 133.sub.1-133.sub.K of the cooling fabric 165 may themselves be the active elements 170.sub.1-170.sub.C that generate the cooling effect on their own, without having distinct active elements connected to the fibers 133.sub.1-133.sub.K of the fibrous base substance 137. For instance, the fibers 133.sub.1-133.sub.K of the cooling fabric 165 may be configured to cool down when absorbing and trapping moisture inside them as the player sweats. Examples of materials that can be used for this purpose may be commercially obtained from CoolCore, Portsmouth, N.H. Other examples of materials that can be used for the cooling fabric 165 may include IceFil by Ventex, Luxicool, Cool Jade, Advansa's Thermo Cool, and HeiQ's Adaptive.
[0177] The quick-drying material (i.e., the fabric 80 of the front 54 of the shoulder pads 13 and similar fabrics of other parts of the shoulder pads 13 in this embodiment) and the cooling fabric 165 may be arranged in any suitable manner in the shoulder pads 13. For example, in this embodiment, a quantity of the quick-drying material in the shoulder pads 13 is greater than a quantity of the cooling fabric 165 in the shoulder pads 13. For instance, in this embodiment, the cooling fabric 165 may be present only in a limited area of the shoulder pads 13 where the cooling effect may be better perceived by the player. Thus, in this embodiment, the cooling fabric 165 is present in a quick-cooling spot of the player's body, i.e., a spot of the player's body that is more efficient at cooling. In this example, the cooling fabric 165 is disposed about the neck opening 58 since the cooling effect at the player's neck may be well perceived by the player. In other examples, the cooling fabric 165 may be disposed in other quick-cooling spots of the player's body (e.g., a crook of the elbow, a wrist, a forehead, an inner thigh, a bend of the knee, or an ankle).
[0178] In some embodiments, a fabric of an inner liner of the shoulder pads 13 (e.g., the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 13 or a similar fabric of another inner liner of the shoulder pads 13) may be a quick-drying and cooling fabric. That is, the fabric may be configured such that (1) its drying rate is relatively high and (2) it provides a cooling effect perceivable by the player. For example, in some embodiments, as shown in
[0179] In some embodiments, as shown in
[0180] More particularly, in this embodiment, each of the vents 166.sub.1-166.sub.F comprises a an opening 163 and a mesh material 263 (i.e., a material having an open texture) disposed within the opening 163 for ventilation. In this example, the vents 166.sub.1-166.sub.F are respectively located in front and back areas of the shoulder pads 13. The vents 166.sub.1-166.sub.F may be disposed in any other suitable manner in other examples.
[0181] In some embodiments, as shown in
[0182] The vents 166.sub.1-166.sub.F may be implemented in various other ways in other embodiments. For example, in some embodiments, a vent 166.sub.x may include the opening 163 without any mesh material in it (e.g., a through-hole extending through the shoulder pads 13). As another example, in some embodiments, as shown in
[0183] In some embodiments, the shoulder pads 13 may comprise an indicator 171 to indicate a current quick-drying effectiveness of a quick-drying fabric (e.g., the fabric 80 of the front 54 of the shoulder pads 13 or a similar fabric of another part of the shoulder pads 13 in this embodiment). This quick-drying effectiveness indicator 171 may be useful in cases where the effectiveness of the fabric at quickly-drying itself can decrease (e.g., after the shoulder pads 13 have been repeatedly used or has been washed with a detergent) in order to allow the player to know when the shoulder pads 13 may no longer work as desired.
[0184] While in embodiments considered above the shoulder pads 13 comprise a quick-drying material that is a fabric making up at least part of an inner liner of the shoulder pads 13 (e.g., the fabric 80 of the inner liner 76 of the front 54 of the shoulder pads 13 or a similar fabric of another inner liner of the shoulder pads 13), in other embodiments, the shoulder pads 13 may comprise a quick-drying material that is another type of material making up another part of the shoulder pads 13. For example, in some embodiments, as shown in
[0185] In some embodiments, the quick-drying material may be anti-microbial. For instance, in some embodiments in which it is a fabric, the quick-drying material may be treated (e.g., via a pad bath or exhaust process) or may have yarn-based anti-microbial or anti-odor technology.
[0186] The elbow pads 15.sub.1, 15.sub.2 are wearable to protect the player's elbows and adjacent parts his/her arms. Each elbow pad 15.sub.x comprises an inner surface 123 for facing towards the player and an outer surface 125 for facing away from the player. In this example in which the elbow pad 15.sub.x is to be worn over the shirt 10, the inner surface 123 of the elbow pad 15.sub.x is configured to contact the outer surface 19 of the shirt 10. In this embodiment, with additional reference to
[0187] While in this embodiment the protective athletic equipment 12 comprises the shoulder pads 13 and the elbow pads 15.sub.1, 15.sub.2, in other embodiments, other articles of protective athletic equipment may be constructed using principles described herein in respect of the shoulder pads 13 and the elbow pads 15.sub.1, 15.sub.2 to provide enhanced moisture management. For example, in some embodiments, as shown in
[0188] As another example, in some embodiments, as shown in
[0189] As another example, in some embodiments, as shown in
[0190] As another example, in some embodiments, as shown in
[0191] As another example, in some embodiments, as shown in
[0192] The athletic gear 11 may comprise any other athletic equipment constructed using principles described herein in respect of the shoulder pads 13 and the elbow pads 15.sub.1, 15.sub.2 to provide enhanced moisture management. For example, in some embodiments, as shown in
[0193] Although in this embodiment the athletic gear 11 is hockey gear, in other embodiments, athletic gear constructed using principles described herein in respect of the athletic gear 11 may be other athletic gear wearable a player playing another type of contact sport (e.g., a full-contact sport) in which there are significant impact forces on the player due to player-to-player and/or player-to-object contact. For example, in other embodiments, athletic gear constructed using principles described herein in respect of the athletic gear 11 may be lacrosse gear for a lacrosse player, football gear for a football player, or baseball gear for a baseball player.
[0194] While in embodiments considered above the athletic gear 11 is for a user playing a contact sport, in other embodiments, athletic gear 11 constructed using principles described herein in respect of the athletic gear 11 may be used in athletic activities other than contact sports in which impact protection is desired.
[0195] In some embodiments, any feature of any embodiment described herein may be used in combination with any feature of any other embodiment described herein.
[0196] Certain additional elements that may be needed for operation of certain embodiments have not been described or illustrated as they are assumed to be within the purview of those of ordinary skill in the art. Moreover, certain embodiments may be free of, may lack and/or may function without any element that is not specifically disclosed herein.
[0197] Although various embodiments and examples have been presented, this was for the purpose of describing, but not limiting, the invention. Various modifications and enhancements will become apparent to those of ordinary skill in the art and are within the scope of the invention, which is defined by the appended claims.
