This application relates to a magnetic fastener system, and more particularly, to a magnetic fastener system for use with protective garments.
Protective or hazardous duty garments are used in a variety of industries and settings to protect the wearer from hazardous conditions such as heat, smoke, cold, sharp objects, chemicals, liquids, fumes and the like. The protective garments often include closures to secure portions of the garment. However, existing closures may not be sufficiently easy to operate and/or sufficiently durable.
In one embodiment the invention is a garment including a body having a first garment portion and a second garment portion, and a releasable fastener configured to releasably couple the first garment portion to the second garment portion. The garment further includes a covering flap movable between a covering position wherein the covering flap covers the releasable fastener and a retracted position wherein the covering flap does not cover the releasable fastener. The garment has a magnetic fastener system configured to selectively retain the covering flap in the covering position.
The coat 10 may include various layers through its thickness to provide various heat, moisture and/or abrasion resistant qualities to the coat 10 so that the coat 10 can be used as a protective, hazardous duty, and/or firefighter garment. For example, the coat 10 may include an outer shell, outer layer or outer material 26, a moisture barrier 28 located inside of and adjacent to the outer shell 26 (e.g. positioned between the outer shell 26 and the torso cavity 22), a thermal liner or barrier 30 located inside of and adjacent to the moisture barrier 28, and an inner liner or face cloth 32 located inside of and adjacent to the thermal barrier 30.
The outer shell 26 may be made of or include a variety of materials, including a flame, heat and abrasion resistant material such as a compact weave of aramid fibers and/or polybenzamidazole fibers. Commercially available aramid materials include NOMEX and KEVLAR fibers (both trademarks of E.I. DuPont de Nemours & Co., Inc. of Wilmington, Del.), and commercially available polybenzamidazole fibers include PBI fibers (a trademark of PBI Performance Fabrics of Charlotte, N.C.). Thus, the outer shell 26 may be an aramid material, a blend of aramid materials, a polybenzamidazole material, a blend of polybenzamidazole fibers, a blend of aramid and polybenzamidazole materials, a polyphenylene benzobisoxazole (PBO) material, a thermostable organic polymer material, such as KERMEL® material sold by Kermel SAS of Colmar, France, a blend of any of the materials listed above, or other appropriate materials.
If desired, the outer shell 26 may be coated with a polymer, such as a durable, water repellent finish or coating (i.e. a perfluorohydrocarbon finish, such as TEFLON® finish sold by E. I. Du Pont de Nemours and Company of Wilmington, Del., or a fluorine free water repellent finish). The materials of the outer shell 26 may have a weight of, for example, between about five and about ten oz./yd2. Moreover, if desired the outer shell 26 may have a self-decontaminating finish or coating applied thereto.
The moisture barrier 28 and thermal barrier 30 may be generally coextensive with the outer shell 26, or spaced slightly inwardly from the outer edges of the outer shell 26 (i.e., spaced slightly inwardly from the outer ends of the sleeves 24, the collar 34 and/or from the lower edge or hem of the coat 10) to provide moisture and thermal protection throughout the coat 10. The moisture barrier 28 may include a semi-permeable membrane layer 28a and a substrate 28b. The membrane layer 28a may be generally water vapor permeable but generally impermeable to liquid moisture. The membrane layer 28a may be made of or include expanded polytetrafluoroethylene (“PTFE”) such as GORE-TEX or CROSSTECH materials (both of which are trademarks of W.L. Gore & Associates, Inc. of Newark, Del.), STEDAIR particulate barrier material sold by Stedfast, Inc. located in Quebec Canada, polyurethane-based materials, neoprene-based materials, cross-linked polymers, polyamid, or other materials. The membrane layer 28a may have microscopic openings that permit moisture vapor (such as water vapor) to pass therethrough, but block liquids (such as liquid water) from passing therethrough. The membrane layer 28a may be made of a microporous material that is either hydrophilic, hydrophobic, or somewhere in between. The membrane layer 28a may also be monolithic and may allow moisture vapor transmission therethrough by molecular diffusion. The membrane layer 28a may also be a combination of microporous and monolithic materials (known as a bicomponent moisture barrier), in which the microporous or monolithic materials are layered or intertwined.
The membrane layer 28a may be bonded, adhered or otherwise coupled to a substrate 28b of a flame and heat resistant material to provide structure and protection to the membrane layer 28a. Thus, either the membrane layer 28a alone, or the membrane layer 28a in combination with the moisture barrier substrate 28b, may be considered to constitute the moisture barrier 28. The substrate 28b may be or include aramid fibers similar to the aramid fibers of the outer shell 26, but may be thinner and lighter in weight. The substrate 28b may be woven, non-woven, spunlace or other materials. In the illustrated embodiment, the membrane layer 28a is located between the outer shell 26 and the substrate 28b. However, the orientation of the moisture barrier 28 may be reversed such that the substrate 28b is located between the outer shell 26 and the membrane layer 28a.
The thermal barrier 30 may be made of nearly any suitable flame resistant material that provides sufficient thermal insulation. In one embodiment, the thermal barrier 30 may include a layer of bulk material 30a in the form of relatively thick (i.e. between about 1/16″- 3/16″) batting, felt or needled non-woven bulk or batting material. The bulk material 30a can include aramid fiber batting (such as NOMEX batting), aramid needlepunch material, an aramid non-woven material, an aramid blend needlepunch material, an aramid blend batting material, an aramid blend non-woven material, foam (either open cell or closed cell), or other suitably thermally insulating materials. The bulk material 30a may trap air and possess sufficient loft to provide thermal resistance to the coat 10.
The bulk material 30a may be quilted or otherwise coupled to a thermal barrier face cloth 30b which can be a weave of a lightweight aramid material. Thus, either the bulk material 30a alone, or the bulk material 30a in combination with the thermal barrier face cloth 30b, may be considered to constitute the thermal barrier 30. In the illustrated embodiment, the thermal barrier bulk material 30a is located between the outer shell 26 and the thermal barrier face cloth 30b. However, the orientation of the thermal barrier 30 may be reversed such that the thermal barrier face cloth 30b is located between the outer shell 26 and the bulk layer 30a. If desired, the thermal barrier 30 may be treated with a water-resistant or water-repellent finish. In one embodiment, the thermal barrier 30 (and/or the coat 10 as a whole) may have a thermal protection performance (“TPP”), as specified in the 1986 revision of the National Fire Protection Association (“NFPA”) 1971, Protective Clothing for Structural Fire Fighting Standards, of at least about twenty, and the coat 10 as a whole may have a TPP of at least about thirty-five, although the TPP values can vary.
Although the moisture barrier 28 is shown as being located between the outer shell 26 and the thermal barrier 30, the positions of the moisture barrier 28 and thermal barrier 30 may be reversed such that the thermal barrier 30 is located between the outer shell 26 and the moisture barrier 28, or additional moisture barrier 28 and/or thermal barrier layers 30 can be utilized or various other orientations or configurations may be used.
The face cloth 32 may be the innermost layer of the coat 10, located inside the thermal barrier 30 and moisture barrier 28. The face cloth 32 can be made of, for example, chambray fabric and provide a comfortable surface for the wearer and protect the thermal barrier 30 and/or moisture barrier 28 from abrasion and wear. The face cloth 32 may be quilted to the adjacent layer (i.e. the thermal barrier 30 in the illustrated embodiment). However, the face cloth 32 is optional and may be excluded if desired. In addition, the coat 10 may not necessarily include the moisture barrier 28 and/or the thermal barrier 30 in certain cases.
Each layer of the coat 10 disclosed herein, including the layers and components described above, as well as those described below, and the coat 10 as a whole and other garments disclosed herein, may meet the National Fire Protection Association (“NFPA”) 1971 standards for protective firefighting garments (“Protective Clothing for Structural Firefighting”), which standards as of the filing date of this application are entirely incorporated by reference herein. The NFPA standards specify various minimum requirements for heat and flame resistance and tear strength. For example, in order to meet the NFPA standards, the outer shell 26, moisture barrier 28, thermal barrier 30 and face cloth 32 must be able to resist igniting, burning, melting, dripping, separation, and/or shrinking more than 10% in any direction after being exposed to a temperature of 500° F. for at least five minutes. Furthermore, in order to meet the NFPA standards, the combined layers of the coat 10 must provide a TPP rating of at least thirty-five.
Alternately or in addition to the NFPA Standard 1971, the coat 10 and other garments disclosed herein may meet standards of other countries or regions, including the European Norm (“EN”) standards for firefighting garments set by the European Committee for Standardization (also known as Comité Européen de Normalisation (“CEN”)). These standards include EN 469:2005 Level 1 and Level 2 certification. The EN standards for firefighter and protective garments in place as of the filing date of this application are entirely incorporated by reference herein.
As shown in
The storm flap 36 can extend generally the entire length/height of the coat 10/fastener 20 and be pivotable about an axis extending along its length between a closed/covering position (
The coat 10 may include a magnetic fastener system 40 which can be used to secure the storm flap 36 in the closed/covering position, and extends parallel to and adjacent to the fastener 20. The magnetic fastener system 40 of
As shown in
In the illustrated embodiment, each support strip 46 includes an inner ply 46a and an outer ply 46b, with the magnets 48 and backing members 50 positioned between the two plies 46a, 46b. The plies 46a, 46b can, in one case, be entirely separate pieces of material, or in another case (as shown in
The plies 46a, 46b can be made of the same or different materials, and in one case are made of a fire resistant textile or fabric, such as aramid, para-aramid or fire resistant cotton material, an E-88 material such as a spunlace flame-resistant meta-aramid material or fabric such as NOMEX® material or KEVLAR® material. In one embodiment, the flap component 42 and body component 44 and/or the associated support strips 46, at least after assembly, are generally water tight such that the magnets 48 and/or backing members 50 positioned therein are generally or completely fluidly sealed from each other and/or the surrounding environment to protect the magnets 48 and backing members 50 and/or first magnet coupling components 49 and/or second magnetic coupling components 53 (as defined below) from moisture, corrosive chemicals, oxygen or the like. In one case, as will be described in greater detail below, the two plies 46a, 46b can be coupled to each other in a facial bond, such as by sonic welding or the like, to form a waterproof seal.
Each of the magnets 48 is, in the illustrated embodiment, generally flat and circular in front view, taking the form of “button” magnets, with their poles oriented perpendicular to the flat end surfaces. In one case the magnets 48 are “solid” and continuous magnets that lack any hole or opening formed therethrough, particularly any center hole/opening and/or any hole/opening through a center thereof. Such a magnet 48 provides ease of construction/assembly, and results in a magnet 48 which is stronger, more robust, and has a better magnetic response such that it is more magnetically attracted to the other magnet(s) 48 and/or backing plates 50. However, the magnets 48 can have any wide variety of shapes and configurations. In one embodiment the magnets 48 are each generally flat and have a relatively small thickness, such as less than about one-half in one case, or less than about one-quarter in another case, of the longest dimension (such as length or diameter) of the magnet 48.
The magnets 48 may in one case have a pull force (either magnet-to-magnet or magnet-to-magnetizable plate) of between about 10 lbs. and about 20 lbs. at a distance of 0 inches, and between about 0.5 lbs. and about 5 lbs. at a distance of 0.2 inches. In one case, the pull force provided by the magnets 48 is selected to be similar to the pull force required to open typical hook-and-loop fasteners used in firefighter turnout gear. The magnets 48 can be permanent magnets made of various materials, and in one case are rare earth magnets, such as neodymium magnets (in one case N48 magnets or 48 MGO megagauss oersteds magnets) with a nickel or other corrosion resistant coating (shown as layer 39 in
As noted above, the flap component 42 and/or body component 44 can also include the plurality of backing members 50, each of which is located between a magnet 48 and at least one ply 46a, 46b of the support strip 46. Each backing member 50 can be made of a material which is non-magnetic but magnetizable, such as ferrous metals, including steel with a nickel or other corrosion resistant coating (see layer 39 in
Each backing member 50 can have a thickness that is less than a thickness of the magnets 48 since in some cases the thinner material may be sufficient to provide the desired functionality (described below) of the backing member 50. In one case each backing member 50 has thickness that is less than about one half, or less than about one third in another case, of the thickness of the associated magnet 48.
The magnets 48/backing members 50 are, in one case, discrete, spaced-apart components that are regularly spaced along the entire length of the support strip 46 and have a spacing therebetween of at least about ½ inch in one case, or at least about one inch in another case, and less than about six inches in another case. This spacing can provide sufficient magnetic connections without causing undue efforts by the wearer in making and breaking magnetic connections, and while providing sufficiently low weight.
As noted above, additionally or alternatively, the flap component 42 and body 12/right front panel 16 (or portions thereof) can be magnetically attracted to each other when the storm flap 36 is in the open/retracted position, to magnetically couple and retain the storm flap 36 in the open position. In this case, as shown in
The backing members 50 can aid in securing the magnets 48 to the support strip 46 during manufacture/assembly of the components 42, 44. In particular, the handling and placement of magnets 48 can in some cases be challenging since machines and equipment typically are made of or include metal or other magnetizable materials, which can cause the magnets 48 to move and/or stick to the machines or equipment during assembly. This can, in turn, make it difficult to precisely locate the magnets 48 on the support strip 46.
Since the backing members 50 can be made of a non-magnetic material, it is relatively simple and straightforward during manufacturing/assembly to supply a support strip 46 (
During use of the coat 10, the backing members 50 may provide protective/shunting effects to reduce certain undesirable effects of the magnets 48. In particular, by shunting the magnetic field of the magnets 48, the backing members 50 reduce the ability of the magnets 48 of components 42 and 44 to attract loose, magnetizable items such as tools, metal portions of the wearer's other garments, etc. In addition, the backing members 50 of the body component 44 shunt or reduce inwardly-facing magnetic field of the magnet 48 to reduce any potential magnetic interference with any medical devices on or in the wearer's body, while the outwardly-facing magnetic field of the magnets 48 of body component 44, which is utilized for closure/attraction, is not effected. However, as will be described in greater detail below it should be understood that the backing members 50 are optional, and when the backing members 50 are not utilized the magnets 48 can be directly coupled to/retained in the associated support strip 46 (e.g. in one case, positioned in contact with both plies of the support strip 46) and/or backing members can be used in place of the magnets 48 on one of the components 42, 44.
After or while the magnets 48 (and backing members 50, if utilized) are placed on the associated support strip 46, the magnets 48 and backing members 50 can be secured in place. In one embodiment, when both magnet 48 and backing members 50 are used on a single component 42, 44 only the backing members 50 (and not the magnets 48) are secured to the support strip 46, such as by adhesives. Such adhesive can be applied during manufacturing/assembly, or may be pre-existing on the support strip 46, such as when the strip 46 includes or takes the form of pressure-sensitive adhesive tape. When the backing members 50 are directly secured to the strips 46, such as by an adhesive, due to the magnetic attraction between the magnets 48 and the backing members 50, it may not be required to separately secure each magnet 48 directly to the support strip 46.
However, the magnets 48 and/or backing members 50 can be secured in place by a variety of methods. For example, as shown in
As shown in
The tube 55 can have two plies 55a and 55b, and be made of a variety of materials. In one embodiment the inner ply 55a (located closer to a wearer of the garment 10 in one case) is made of an outer material or fabric 57 such as an E-88 material such as a spunlace flame-resistant meta-aramid material or fabric such as NOMEX® material, and an inner layer 59 such as a foam, and more particularly a closed cell foam to providing cushioning and protection to the support strip 46 and magnets 48/backing members 50. The outer ply 55b of the tube 55 (located more distant from a wearer of the garment 10) can in one case be made of a para-aramid material. In one case, the outer ply 55b is made of a relatively thin material (thinner than inner ply 55a, in one case due to the foam layer 59). Making the outer ply 55b of relatively thin material reduces the distance between the magnets 48/backing members 50 of the support strip 46, relative to the other support strip 46, to provide increased magnetic response and attraction. Alternatively both plies 55a, 55b of the tube 55 can be made of the same material, including any of the materials outlined above for any layer or ply 55a, 55b of the tube 55, and combinations thereof.
The magnets 48 of the flap component 42 can be arranged such that their poles are opposite to the poles of the magnets 48 of the body component 44, when the flap component 42 and body component 44 are stacked on top of/positioned adjacent to each other in a thickness direction, as shown in
The magnets 48/backing members 50 of the flap component 42 can generally have a spacing that corresponds to a spacing of the magnets 48/backing members 50 of the body component 44. In one case, the geometric centers of the magnets 48/backing members 50 of one component 42, 44 are generally aligned with the geometric centers of the magnets 48/backing members 50 of the other component 42, 44 (such as when the storm flap 36 is in the closed or covering position). In another case each magnet 48/backing member 50 of one components 42, 44 can at least partially overlap with a corresponding magnet 48/backing member 50 of the other component 42, 44, in a direction perpendicular to the thickness of the coat 10, such as when the storm flap 36 is in the closed position.
In an alternate embodiment, as noted above and shown in
In the embodiment of
When the magnetic coupling components 49, 53 of both the flap component 42 and the body component 44 take the form of magnets 48, or more particularly magnets 48 with a backing member 50 as shown in
The flap component 42 and body component 44 can each be relatively long, linear strips having a length significantly greater than their width. For example, each of the flap component 42 and body component 44 can be generally flat and elongated, and have a length at least about five times the width thereof in one case, or at least about ten times greater than the width thereof in another case. As shown in
As noted above, the magnetic fastener system 40 can in one case be utilized to secure the storm flap 36 in its closed position (shown as magnetic fastening system 40a in
In the embodiment of
Moreover, the magnetic fastener system 40 can be used in any of a wide variety of garments beyond protective and fire fighter garments and indeed used in any of a wide variety of applications, systems or methods. For example,
The magnetic fastener system 40 can provide a durable, robust and protectable fastener system which retains its strength over time, including after repeated exposure to heat, laundering, etc. In addition, operation of the magnetic fastener system 40 is relatively easy. In order to separate or open the magnetic fastener system 40, the movable/pivotable component (flap 42) and the fixed component (body 44) need only be manually pulled apart, and the wearer is not required to identify any particular tabs or release mechanisms, or start fastening or unfastening at a particular location, as is required for use with zipper systems or the like. The magnetic fastener system 40 can be coupled or closed simply by pivoting the movable/pivotable component in place on or over the body portion. In addition, the magnetic fastener system 40 can be operated without fine motor skills, which can provide ease of use to a wearer who is wearing gloves, or when time is limited.
A garment, such as a coat 10 and/or trousers 56, can include multiple magnetic fastener systems 40 utilized therein. For example, as outlined above and shown in
As shown in
If desired, each of the strips 46′, 46″ can include color coding, a visual identifier or printed indicia (collectively termed “indicia” herein) or the like 77 to illustrate the polarity and/or use thereof (e.g. to indicate which component should be installed in the movable part versus the fixed/body 12 of the garment 10 and/or which side should face in which direction). For example, a segment or strip of color indicia 77 (see
In the embodiment of
In order to utilize the strips 46′, 46″, the garment assembler receive the strips 46′, 46″, each as a continuous strip, for example in one case from a manufacturer or supplier of magnetic components. The garment assembler can simply cut or separate the strips 46′, 46″ at the desired locations to provide the number of desired magnetic coupling components 49, 53, and the resultant, smaller shorter strip can then be sewn or secured into the garment at the appropriate location and manner. For example, first smaller strips of the first 46′ and second 46b″ strips can be used as the flap component 42 and body component 44, second or supplemental smaller strips of the first 46′ and second 46″ strips can be used as part of a pocket closure system 40b, 40c, etc. Thus the strips 46′, 46″ can provide a convenient system for incorporating the magnetic coupling components 49, 53 in a garment which can be easily implemented during garment manufacture, and can provide a predetermined number of magnetic coupling components 49, 53 for the entire garment.
With reference to
The throat tab 62 spans/extends across the fastener 20 when the throat tab 62 is in the closed position, and does not extend across the fastener 20 when the throat tab 62 is in the retracted position. The throat tab 62 may span, and cover, a gap 63 (
The coat 10 can include a throat tab closure system 61 including a first “mechanical” or non-magnetic fastener system 66 to retain the throat tab 62 in the closed position. The mechanical fastening system 66 may in one case lack any magnetic parts in one case, and/or lack any magnetic or magnetizable parts, components or materials (such as metal, or at least sufficient metal to be magnetized and act as a fastener/closure) in another case. In particular, in the illustrated embodiment the first fastener system 66 includes a first portion 68, or portion of hook material 68, positioned on and near a distal end of the throat tab 62, and a second portion 70, or portion of loop material 70, positioned on the body 12 of the coat 10 or on the collar 64. The first or hook 68 and second or loop 70 portions can cooperate, when pressed together, to secure and retain the throat tab 62 in the closed position. Of course, if desired, the positions of the hook and loop material can be reversed such that the loop material is positioned on the throat tab 62 as the first portion 68, and the hook material is positioned on the body 12/collar 64 as the second portion 70. Moreover, it should be understood that various fasteners can be used as the non-magnetic fastener system 66 in place of the hook-and-loop fastening systems such as in one case other mechanical fasteners including snaps, loops, clasps, ties, buttons or the like.
The first 68 and/or second 70 portions can be relatively elongated to provide increased flexibility/adjustability in the operation of the throat tab closure system 61. In particular, in the embodiment shown in
The coat 10 can include a second or magnetic fastener system 72 which can retain the throat tab 62 in the retracted position. In particular, in one case the throat tab 62 includes a first or throat magnetic coupling component 74 including a magnet and/or magnetizable portion. The throat magnetic coupling component 74 can take the form of a magnet, such as magnet 48 in combination with the backing plate 50 (see
The throat 74 and body 76 magnetic coupling components can magnetically interact, when the throat tab 62 is in the retracted position, to retain the throat tab 62 in the retracted position. For the sake of clarity, it is noted that the throat magnetic coupling component 74 can take the form of a magnet and the body magnetic coupling component 76 can take the form of a magnetizable material, or vice versa, or both the throat 74 and body 76 magnetic coupling components can take the form of magnets 48. Moreover, if desired, the backing member 50 as described above can be utilized in conjunction with any magnets 48 utilized as the throat 74 and/or body 76 magnetic coupling component, but if desired the backing members 50 can be omitted. The magnetic fastener system 72 can utilize the various features shown and described above with respect to magnet fasteners systems utilized in other portions of the coat 10. In one case, the magnetic fastener system 72 can include multiple magnets 48 and/or backing members 50 spaced in the circumferential direction on the throat tab 62 and/or body of the coat 10 as shown in
Accordingly, as can be seen, the throat tab closure system 61 includes a non-magnetic fastener system 66 to retain the throat tab 62 in a closed position, and a magnetic fastener system 72 to retain the throat tab 62 in the retracted position. In one case, on the throat tab 62, the non-magnetic fastener system 66/first portion 68 is positioned vertically above (e.g. closer to the upper edge of the collar 64 and/or throat tab 62) the throat magnetic coupling component 74 when the throat tab 62 is in its closed position to help provide a more secure coupling and reduce loose flapping of the throat tab 62. The magnetic fastener system 72 of
In one case, because the non-magnetic fastener system 66 may remain cooler and when exposed to heat and/or not be as thermally conductive (since it can be made of non-metallic components), it may be desired to use the non-magnetic fastener system 66 along the front of the coat 10 where a wearer may be exposed to more heat and/or where the non-magnetic fastener system 66 may be exposed to more sensitive portions of the wearer (e.g. the face and/or front of the neck). In this case only a single magnet/magnetizable component/metallic component (the throat magnetic coupling component 74) is located in the front collar area when the throat tab 62 is closed, and furthermore the collar 64 is positioned between that component 74 and the wearer to provide additional protection to the wearer from the throat magnetic coupling component 74.
By locating part or all of the magnetic fastener system 72 along the back of the neck, and by not placing any magnets, metal, or magnetizable material on the front of the collar 64, the user and magnetic fastener system 72 may be more isolated and protected from front-facing heat sources. Thus, in one case, the front of the collar 64 and/or the front of the coat 10 (e.g. in one case, those portions of the collar 64/body 12 in the front half of the coronal plane) lacks any magnetic, magnetizable and/or metallic components, materials or components and/or lacks any components that the throat magnetic coupling component 74 can magnetically interact with to secure the throat tab 62 in the closed position (e.g. lacks any magnetic attraction that is sufficiently strong to sufficiently secure the throat tab 62 in place).
In addition, if a magnetic fastening system were to be used to secure the throat tab 62 in the closed position, such an arrangement could limit the adjustability of the throat tab 62; e.g. the throat tab 62 may only be able to be secured in a single position and/or with limited adjustability. Some wearers may want to the throat tab 62 to be secured in looser or tighter configuration, and the non-magnetic fastener system 66 provides greater flexibility as described above.
With reference to
In one case the trousers magnetic coupling component 84 can be entirely located in the lower 5% of the trousers 56, or in the lower 10% of the trousers 56 in another case, or in the lower 25% of the trousers 56 in yet another case, or the lower 33% of the trousers 56 in yet another case. The trousers magnetic coupling component 84 can be located at any circumferential position of the leg of the trousers 56, but in one case is located on a circumferential outer surface of the trousers 56 (opposite the inseam) or within about 15 degrees thereof. Although
The trousers 56 of
At least one of the trousers 84 or footwear 86 magnetic coupling components may be a permanent magnet, while the other one of the associated trousers 84 or footwear 86 magnetic coupling component may be either a permanent magnet or a magnetizable material. Moreover, if desired, the backing member 50 as described above can be utilized in conjunction with any magnets 48 utilized as the trousers 84 or footwear 86 magnetic coupling components, but if desired the backing members 50 can be omitted. The trouser/boot coupling system 80 can utilize the various features shown and described above with respect to magnet fasteners systems 40 utilized in other portions of the garment.
The trousers 84 and footwear 86 magnetic coupling components can magnetically interact when the trousers 56 and boots 82 are worn to retain the trousers 56 in place and prevent the trousers 56 (in particular the legs of the trousers 56) from being pulled upwardly, thereby providing protection to the wearer's legs/ankles. The magnetic connection between the trousers 84 and footwear 86 magnetic coupling components may be able to be manually overcome by a wearer to decouple the trousers 84 and footwear 86 magnetic coupling components, thereby allowing the trousers 56 and/or boots 82 to be doffed. The trousers/boot coupling system 80 thus provide an intuitive, and easy-to-use system for coupling trousers 56 to footwear 82, with little or no extra motion required by the wearer to secure or break the connection.
Having described the invention in detail and by reference to the preferred embodiments, it will be apparent that modifications and variations thereof are possible without departing from the scope of the invention.
