Description

DescriptionTitle of Invention: Magnetic Coupling for ArticlesFIELD OF THE INVENTION

[0001] The present subject matter relates to, a magnetic coupling mechanism / method for coupling two portions of an article with each other, more efficiently and securely.BACKGROUND OF THE INVENTION

[0002] Known market available magnetic coupling methods / systems, have several drawbacks and disadvantages, such as but not limited to, Metal-on-Metal grinding, sideways-slipping, presence of medium in-between the article portions that couple, wear / tear of the article's material as well as the coupling components / devices, limited long-term endurance and many other well-known drawbacks within this domain.

[0003] The first drawback being that when magnetic components, are not encased in a non- corrosive, weather-resistant layer, in such cases metal-on-metal grinding may cause, the topmost protective paint or galvanized-layer to chip-off during use, exposing inner layers that may get corroded due to weathering over time. Further, metal-on-metal contact reduces endurance, as each time they make contact, they experience impact-loading during coupling with each other, which negatively impacts the life-time of the magnetic components.

[0004] Secondly, a common drawback of magnetic coupling devices is sideways-slipping, when having a flat contact face between the opposite portions causes unintended separation / de-coupling, essentially eliminating magnetic couplings from being considered for any demanding scenarios / situations, wherein the coupling must not de-couple unless desired by the user to do so, such as when the article is a wearable item, such as a bands, apparels, suits, belts, etc. This is a matter of major concern as the coupling devices must remain flat to be used in wearable items, which increase the chances of this kind of sideways-slipping of the devices, when placed under a situation of duress, or accidentally when any kind of tangential force is applied, which renders most magnetic coupling devices less-desired for such applications. As these prior devices either, cause tears / cracks in the material of the article or decouple from each other, in such scenarios.

[0005] Thirdly, another drawback most magnetic coupling devices have substantial volumes / protrusions that extend much above the surface of the article, when these are stitched / sewn / glued with the article, hence when the devices couple with each other during operation, a medium (of air / water, specifically) is always present between the portions of the article, due to the thickness of the device in-between the two portions of the article. This medium primarily cause fluid-dynamic (aerodynamic or hydro-dynamic) drag, if the article (wing-suits, glide-suits, dive-vests, dive-suits, safety belts / harnesses, etc.) is being used for such purposes. Secondarily, this medium may cause, creases and undesired undulating- patterns, on the fabric / material of the article, causing loss of aesthetic appeal. Tertiarily, this medium allows a volume of the coupling device in-between the two coupling portions of the article, which provides encouragement to cracks / tears to form in the material / fabric of the article at the location surrounding such a coupling device, eventually with time and wear these cracks / tears give-way to complete-failure of such material from which the coupling device protrudes.

[0006] Further, a major disadvantage of previous magnetic coupling devices, is that they are prone to wear-tear and usually perform very poorly in terms of long-term endurance, compared to other types of coupling devices. Due to the intermittent knocking / impacts against each other, between the pair of magnetic devices, they become prone to cracking, or de-magnetization over-time, if sufficiently thick-layers are not provided for the protection of each of the magnetic devices / units. Furthermore, if the fabric layers have a medium inbetween them due to the magnetic devices as explained in the previous paragraph, in that case, the fabric layers are enabled to rub against each other, and hence, are worn-out quickly over time, when compared to other type of coupling devices.

[0007] The purpose of the present subject matter presented below, is particularly to provide a simple, economic, swift and efficient solution to the all the above described drawbacks within the art, in order to, at least partially overcome most of the above-mentioned disadvantages.SUMMARY OF THE INVENTION

[0008] The present subject matter relates to, a magnetic coupling mechanism for an article, comprising, a pair of encased magnetic units having an identifiable coupling-face and non- coupling-face. These encased magnetic units are located on two portions of the article, that can be coupled by a user, if desired. Further, the mechanism comprises a pair of appropriate apertures, for receiving the pair of encasements within the fabric / material of the article portions for coupling, that allows these portions of the article to couple-flatly against each other during operation.

[0009] In another embodiment, the present subject matter relates to, a magnetic coupling mechanism for an article, comprising, a pair of identical magnetic units, having opposite polarity with respect to each other. Further, the magnetic units are encased with a polymer layer to form a pair of encasements, having an identifiable coupling-face and non-coupling- face. Furthermore, the coupling-faces of both the encasements face towards each other for direct contact, during operation. The article has two couplable portions, which receive the pair of encasements. Moreover, an appropriate pair of apertures are provided in the fabric / material at the couplable portions of the article, for integrating each of the pair of encasements and especially their coupling-faces, which allows these portions of the article to couple-flatly against each other during operation. Specifically, the apertures in the material / fabric of the article prevents wear / tear of the material / fabric when the encasements make contact during operation.

[0010] In some embodiments of the magnetic coupling mechanism for an article, the non- coupling-face of the encasements is provided with more cross-sectional area, compared to the coupling-face of the encasements. Further, this additional cross-sectional area, is utilised for permanently coupling both of the encasements, at the aperture of material / fabric of the article. Furthermore, the permanently coupling, is selected from any of the coupling mechanisms, such as sewing, stitching, gluing, riveting, thermal bonding, or any combination these or other known coupling methods / mechanisms.

[0011] In some embodiments of the magnetic coupling mechanism for an article, the encasements have any custom shape / profile, specifically with respect to the outline of the coupling / non-coupling -faces. However, the side-profile of the encasement is always a stepped-profile, with a bias towards the non-coupling-face.

[0012] In some embodiments of the magnetic coupling mechanism for an article, the polymer layer used for encasements has any chemical structure, selected from the group consisting of, polyurethane, thermoplastics, HDPE, LDPE, polyethylene, polypropylene, ABS, soft- plastics, PVC (poly-vinyl-chloride), fibre-reinforced polymers, composites, or any combination thereof.

[0013] In some embodiments of the magnetic coupling mechanism for an article, each permanent magnet unit, is made of neodymium material. Further, in some other embodiments of the magnetic coupling mechanism for an article, each magnet unit, is segmented into multiple pieces / units / elements, operating in tandem to provide enhanced magnetic polarity on the coupling-face of the encasements. Furthermore, in some embodiments of the present subject matter the magnetic units may be, particularly formed of N52 neodymium magnets, or even more particularly formed by N52H neodymium magnets.

[0014] In some embodiments of the magnetic coupling mechanism for an article, a unique identification / logo is imprinted through methods, such as, heat-printing, laser-engraved, indenting, embossing, debossing, branding, on the coupling-face of the both the encasements.

[0015] In some embodiments of the magnetic coupling mechanism for an article, the coupling-faces of the encasement pairs have, one or more interlocking surface augmentations with respect to each other, in order to ensure a slide-free coupling, during operation. Further in some other embodiments, the one or more interlocking surface augmentations have a noncircular profile / shape, in orderto prevent rotation. Furthermore, in alternative embodiments, the interlocking surface augmentations have a circular profile / shape, especially when two or more interlocking surface augmentations are present.Advantages and utility of the present invention

[0016] The present subject matter provides significant advantages compared to other coupling devices as it provides many benefits such as but not limited to, a protective layer on the magnetic unit, arrestation of sideways-slipping motion, flat-coupling of the article portions without any intermediary mediums, substantial reduction in wear / tear of the article as well as the device, and overcomes many other well-known drawbacks within this domain. Further, the magnetic coupling device of the present subject matter, is more durable, cost- effective, failure-proof solution, as well as it provides significant fluid-dynamic and aesthetic advantages, compared to the other type of coupling devices available in market.

[0017] Furthermore, a list of advantages of the embodiments of the present subject matter, as provided below:

[0018] Strength customization- By varying the strengths of the magnetic units and / or the thickness of the encasement polymer, allows for customization of the strength and usage in accordance with specific needs of the users. Stronger magnetic units are utilised for heavy- duty applications, ensuring a secure and reliable connection. Weaker magnetic units, on the other hand, are ideal for lighter applications, where excessive force is not required, or where the weight of the magnetic unit is a hinderance.

[0019] Durability- The use of a polymer casing, significantly enhances the durability and endurance of the magnetic units, utilised within this magnetic coupling mechanism. Essentially, the polymer adds a layer of protection to the magnetic units, making them lesssusceptible to damage or breakage. The encasing polymer also helps in prevention of corrosion of the magnets, ensuring their long-term functionality. This polymer layer provides physical protection against impacts, wear-tear and other environmental elements, as well as, safeguards the magnetic units against potential degradation of their magnetic-force.

[0020] Aesthetic appeal- The encasements have interlocking-faces that can be designed / styled in various shapes, profiles, depths and sizes, allowing for aesthetically pleasing visual aesthetics to be achieved. This makes it a suitable choice for products where the coupling mechanism is visible and contributes to the overall look and feel of the item. Further, since the polymer layer may have any colour or surface augmentations, it allows the manufacturer to incorporate any type of colour and / or branding into the design of the encasements, and especially their coupling-faces that are visible to the users, when the coupling mechanism is not in operation. Furthermore, the custom shape / profile of the encasements provides versatility in design, to suit various kinds of articles, apparels, accessories, their further types and styles.

[0021] Versatile applications- The magnetic coupling mechanism can be used in a wide range of applications. It can be utilized in clothing, bags, shoes, accessories, home-decor, automotive, and many other industries, where quick and secure fastening is desired.

[0022] Soft-Close- This magnetic coupling mechanism eliminates the need for traditional mechanical coupling mechanisms, such as push-buttons, zippers, Velcro, or other similar coupling mechanisms, which produce noise during operation. Essentially, the invention of the present subject matter, eliminates the noise associated with these traditional coupling mechanisms, produced during opening or closing of such mechanisms, by providing a quieter and more seamless user experience.

[0023] Easy and quick fastening- The magnetic coupling mechanism with opposing interlocking-faces, formed by the surface augmentations, offers a convenient and fast way to secure items together. Users only need to bring the two faces close to each other, and the magnets automatically attract and lock the components in place.

[0024] Easy maintenance- The magnetic coupling mechanism is relatively easy to clean and maintain. Unlike traditional coupling mechanisms that may have small crevices or moving parts, the interlocking faces can be wiped clean easily with a damp cloth. This makes the magnetic coupling mechanism more hygienic and significantly reduces the chance of dirt, debris, or organic-matter (especially, micro-organisms, viruses, etc.) accumulation.

[0025] User-friendly and safe- The magnetic coupling mechanism is extremely user-friendly for people of all ages and abilities. It requires very less dexterity and strength on the part of the user, in order to operate this mechanism, compared to many traditional coupling mechanisms, making them especially, ideal for babies / kids or, individuals with limited hand mobility or other disabilities.

[0026] Intuitive by Design - The magnetic coupling mechanism is intuitive in the sense, that it enables a body of the article to flawlessly blend, the coupling mechanism into the body of the article.

[0037] The features and advantages of the present subject matter, just as they are stated in the claims, will now be described in detail with reference to the appended drawings, showing several examples of deployment configurations / embodiments for the present invention.

[0038] In the case, where there are two or more definitions of a term that is used and / or accepted within the known art, the definition of the term as used herein, is intended to include all such meanings unless explicitly stated to the contrary.

[0039] For purposes of the detailed description of the preferred embodiments, the following definitions are used:

[0040] Throughout the present subject matter, the term "article" is referring to any kind of utilitarian-item where quick and secure fastening is desired. The article encompasses items such as but not limited to, clothing, bags, purses, shoes, belts, clip-ons, accessories, homedecor, automotive / aeronautical safety-equipment, and many other industries. The clothing / wearable articles further encompass all types of clothing, garments, suits, or any other type of wearable devices (for e.g. smart watches, AR / VR head gear, helmets, safety belts, etc.), which essentially require a user-controlled quick coupling-decoupling mechanism. In some embodiments, these suits as mentioned here, are sporting / activity suits such as, wetsuits, wing-suits, dive-suits, glide-suits, etc. It is important to note that the body of the article, may be made up of any suitable material and have any suitable design / form, that is appropriate for the type / purpose of such article. Further, it should be noted that, the article may be made of any suitable material, including but not limited to any fabric / material which is formed by, one or more layers of same, or, different materials that have been either bonded, processed, sewn, stitched, glued, pressed, cast, rolled and / or riveted together, to form any suitable / desired composite. Furthermore, more importantly this fabric / material is essentially the prime substance that forms the body of the article. Although, it should be noted that for example, that in some articles may encompass less than even 50% of a prime fabric / material forming the body of the article, along with a combination of an array of other suitable materials and / or components (such as in cases, when the article is a wearable smart device, such as smart watches, VR headgear, etc.). Yet, in other examples, where the article is a suit, dress, clothes, tie, belt, handbag, purse, suit-case, etc., the articles may encompass 90% of the prime fabric / material forming the body of the article.

[0041] Throughout the present subject matter, the terms "magnetic units" or just "magnets" refers to a magnetic unit formed by one or more magnets, having a magnetic polarity. Here, the magnets may be permanent magnets, induced magnets, ferrite, neodymium, rare-earth magnets, halbach-arrays, or any combination of these and other known magnetic materials, to obtain a desired polarity on one side of a flat face of the body. Further, the term "pair ofidentical magnetic units" as used within the claims, refers to a pair of such magnetic units, wherein both coupling-faces of the pair, have an opposite polarity with respect to the other coupling-face, and hence attract each other when in close proximity. Furthermore, in some embodiments of the present subject matter the magnetic units may be, particularly formed of N52 neodymium magnets, or even more particularly formed by N52H neodymium magnets.

[0042] Throughout the present subject matter, the term "encased" or "encasement" refers to the process of encasing each of the magnetic units, by enveloping / cocooning / sandwiching each magnetic unit with a polymer layer on all sides. This encasement of each magnetic unit, provides physical protection to each of the magnetic units with respect to, impacts, wear / tear, elements and even corrosion or degradation, hence increasing the durability and endurance of each of the magnetic units. Further, each encasement, is such that it has an identifiable coupling-face and non-coupling-face. The process utilised for encasing of the magnetic units, may be any of the methods, such as injection-moulding, lamination, casting, sprayed-on, or other known processes, that obtain the same results as illustrated and is known within the art.

[0043] Throughout the present subject matter, the term "couplable portions" is essentially referring to the two portions of the article, that the user / manufacturer intends to couple / decouple with respect to each other, as desired by a user. The location or orientation of each of these pair of couplable portions for each article, are generally selected by the producer, tailor, designer or article manufacturer while the article is being manufactured, wherein each of the encasements having the magnetic units are permanently coupled to these portions of material / fabric of the article.

[0044] Throughout the present subject matter, the terms "aperture" or "apertures" refer to a cut-out, a vent, or simply a rupture, in the body of the article, within essentially the prime fabric / material of the article. These apertures are located at the couplable portions on the body of the article, in order to specifically integrate the coupling-face of the encasements, i.e. the volume of encasement which has the less cross-sectional area, in other words. These apertures are appropriately wide enough for receiving the pair of encasements, in such a way as to allow the coupling-face of each encasement to face its counterpart encasement's coupling-face, during operation. This aperture, may also be referred to as a recess, receptacle, or a cavity, within some embodiments of this invention. Further in some embodiments of the present subject matter, it should be understood that the aperture forms a lip-area over each of the step of the encasement, which is utilised for permanently coupling the encasement to the material / fabric of the article.

[0045] Throughout the present subject matter, the term "couple-flatly" as used within the claims, refers specifically to, the aspects that, is previously disclosed in the background above, regarding the coupling devices that protrude above the surface of the fabric / material of the article. This protrusion causes a medium to form between the two couplable portions of the article. However, in case of the presented magnetic coupling device for an article, as described in the present subject matter, this is not the case, because each of the encasements are integrated within an aperture of the body of the article, that is devised for this express purpose, allowing the coupling-face of the encasement to be in level-plane with respect to the surface of the fabric / material of the body of the article. Hence, the couplable portions ofthe body of the article, may couple flatly against each other, eliminating any kind of medium to be formed in-between them, when they are detachably coupled during operation. This ensures a gap-less coupling between the two couplable portions of the body of the article. This feature essentially, sets the magnetic coupling mechanism disclosed in the present subject matter, apart from all the other types of magnetic coupling mechanisms, because the couplable portions of the body of the article here, create a very minimal gap / volume / space in between these couplable portions, during coupled / operating state. This in turn allows for an intuitive design to be realised for the body, with respect to each of the article, that is utilising the magnetic coupling mechanism disclosed in the present subject matter, which enables this mechanism to be utilised in plethora of articles belonging to several diverse fields, as disclosed above in paragraph 40.

[0046] Throughout the present subject matter, the term "cross-sectional area" as referred to within the claims, intends to express that, during the encasement process of the magnetic units to form the encasements, it is performed in such a way as to form a stepped edge / side- profile, along the side-faces of each of the encasements, specifically in-between the couplingface and the non-coupling-face of each of the encasements, wherein due to the step the encasement has, more cross-sectional area towards the non-coupling-face when compared to the coupling-face, when viewed in a lateral plane. This produces an additional cross- sectional area halfway between the non-coupling and coupling faces, that is also referred to as a step-area because it rises half-way from the non-coupling-face towards the couplingface. This step-area is utilised for permanently coupling each of the encasement to the fabric / material of the article, specifically with the lip-area of each of the aperture. Allowing the coupling-face to snuggly-fit against the aperture / cut-out / vent / rupture within the layer / s of fabric / material of the body of the article, in order to maintain the coupling device / mechanism coupling-plane to be almost same as the level or plane of the fabric / material of the article.

[0047] Throughout the present subject matter, the term "permanent coupling" is referred to as any type of suitable permanent coupling method, in order to couple the encasement with respect to the fabric / material of the article. The permanent coupling may be of any type, but not limited to examples such as, sewing, stitching, gluing, riveting, thermal bonding, or any combination thereof. Further, it should be noted that, permanent coupling is not illustrated in the attached drawings of the present subject matter, however it would be obvious to a person skilled in the art, as to where the intended location and manner in which the permanent coupling would most likely be incorporated within the mechanism, based on the provided illustrations.

[0048] Throughout the present subject matter, the term "custom shape / profile" refers to any shape for example, but not limited to, such as, circular, triangular, quadrilateral, polygonal, star-shaped, crescent-shaped, emoji-shaped, or any specific logo / design, as may be suitable for application and desired by the user / manufacturer of the article.

[0049] Throughout the present subject matter, the term "polymer" as referred to within the claims, is selected from the following group of compounds, but not limited to, such as, polyurethane, thermoplastics, HDPE, LDPE, polyethylene, polypropylene, ABS, soft-plastics, PVC (poly-vinyl-chloride), fibre-reinforced polymers, or any combinations / blends of these compounds and / or other additives, as is known within the art.

[0050] Throughout the present subject matter, the term "eye-catching colour" as referred to within the claims, intends to express that the polymer, that is used for encasing the magnetic units has a colour, which is capable of catching attention easily even from a distance, allowing the user or even an observer, regarding the current status of the coupling mechanism, of the article. Further, it would be obvious to a person skilled in the art that, this effect may be affected, even with dull colours, if the polymer colour is in stark contrast with the colour of the fabric / material of the article. Furthermore, in other embodiments, the colour of the polymer, may be selected from the higher-wavelength section of the visible-spectrum, such as Red, Orange, Yellow, etc. Moreover, in some other embodiments of the present subject matter the colour of the polymer may be Orange, specifically the orange colour R255 G91 BO.

[0051] Throughout the present subject matter, the term "segmented" as referred to within the claims, intends to express that each magnetic unit as described above, in some embodiments is formed by, one or more magnetic components / pieces / units / elements. These segmented magnetic units have multiple pieces / units / elements working with each other, to provide an enhanced desired magnetic polarity on the coupling-face of the encasements. In some other embodiments the magnetic units, utilise these segmented components to produce a halbach-effect, in order to achieve this objective.

[0052] Throughout the present subject matter, the term "imprinted" as referred to within the claims, intends to express that through methods, such as, heat-printing / laser-engraved, indenting, embossing, debossing, branding, a unique logo / identification is permanently etched / depicted on the coupling-face of the encasements.

[0053] Throughout the present subject matter, the term "interlocking surface augmentations" is refers broadly to surface embossing / debossing on the coupling-face of the pair of encasements, such that when they make contact during operation the embossed surface augmentation of one coupling-face of the pair, is perfectly received by the debossed surface augmentation of the other coupling-face of the same pair of encasements. These interlocking surface augmentations restrict the magnetic coupling device from sliding in a tangential direction with respect to the direction of contact. Hence, eliminates any chance of sideways-slipping of the encasements with respect to each other, even under extreme circumstances of duress or tangential-forces. These interlocking surface augmentations, may be of any suitable kind, such as but not limited to, plateau-valley, hills-gorges, waves / egg- trays, zigs-zags, jaws / teeth, ridges, pins-holes, shafts-slots, male-female, emboss-deboss, or any combination thereof.

[0054] Throughout the present subject matter, the term "non-circular profile" as referred to within the claims, specifically relates to a possible shape of the interlocking surface augmentations. As, described as being a non-circular shape, there is very little chance of one encasement rotating with respect to another encasement pair, in such cases.

[0055] Throughout the present subject matter, the term "circular profile" as referred to within the claims, specifically relates to a possible shape of the interlocking surface augmentations. As, described as being a circular shape, there is a chance of one encasement rotating with respect to another encasement pair, in such cases, hence, this profile is only suitable to be used when at least two or more of these interlocking surface augmentations are being utilised on the coupling-face of the encasements, in order to restrain such a rotating motion, as described. Further, in yet other embodiments, where a rotating motion betweenthe pair of encasements, during coupling is beneficial for the user, only a single circular profile may be utilised as the shape / profile for the interlocking surface augmentations.

[0056] Below provided are the major embodiments of the present subject matter, in order to provide context to the drawings as well as the claims, provided within this application.Embodiments of the Invention and parts thereof

[0057] As disclosed within the present subject matter, an embodiment of the magnetic coupling device for an article comprises, a pair of identical magnetic units, having opposite polarity with respect to each other. Further, the magnetic units are encased with a polymer- layer to form a pair of encasements, having an identifiable coupling-face and non-coupling- face. Furthermore, the coupling-faces of both the encasements face towards each other for direct contact, during operation. The article has two couplable portions, which receive the pair of encasements. Moreover, an appropriate pair of apertures are provided within the fabric / material at the couplable portions of the article, for receiving the pair of encasements, which allows these portions of the article to couple-flatly against each other, during operation. Specifically, the aperture in the material / fabric of the article prevents wear / tear of the material / fabric when the encasements make contact, during operation.

[0058] A first exemplary embodiment of the magnetic coupling device of the present subject matter, is illustrated in FIG. 1. The magnetic coupling mechanism for an article 9, comprising, a pair of encasements, 10 and 20 respectively, having an identifiable coupling-face and non- coupling-face. Here, the encasements 10 are illustrated as being on one side of an article, while the other encasements 20 are on the lapel of the article, that is located on the other side of the article. However, these magnetic units only provide a possible location of the mechanism, these pair of encasements may be located on any two portions of the article, that require to be coupled by a user / manufacturer, if desired. This is further depicted in FIG. 1, by the other pairs of such encasements, 11 and 21 respectively, such as located on the two ends of the collar of the article. Similarly, at the cuffs of the article, exists a pair of encasements, 12 and 22 respectively as depicted here, that are employed as a coupling means / mechanism, within this illustration presented by FIG. 1. It is important to note that article 9 in figure 1 depicts an apparel, however as described above and is well known within the art, that such coupling mechanisms / devices, may be employed for various other articles as well, which are not an apparel (not shown in the present subject matter).

[0059] As illustrated in FIG. 2 of the present subject matter, a magnetic coupling mechanism for an article 9, from FIG. 1 is depicted here, with a cross-sectional view.

[0060] Specifically, FIG. 2a illustrates a cross-sectional perspective-view of a single encasement 10, from a pair of encasements. Here, the cross-sectional view of the encasement 10, clearly illustrates one of the magnetic units 8, from the pair of magnetic units with opposite polarity. More importantly, this figure illustrates that the fabric / material of the article 9, has an appropriately shaped aperture / recess / receptacle / cavity, in order for it to receive the encasement 10. Further, it can be seen here that, the encasement 10 has a stepped side-profile, wherein the coupling-face has less cross-sectional area, as compared to, the non-coupling-face of the encasement 10.

[0061] Specifically, FIG. 2b illustrates a cross-sectional front-view of a single encasement 10, from a pair of encasements. Further, here it can be seen that the fabric / material of the article 9, forms a lip-area over the step-area of the encasement, as disclosed in description of FIG.2a. This lip-area of the aperture is employed for the purposes of permanent coupling, of each of the encasements with its respective aperture on the article, by the manufacturer.

[0062] Further, in some embodiments of the present subject matter, the encasements 10 have any custom shape / profile, other than the shape depicted here in FIG. 2. Furthermore, in some embodiments of the present subject matter, the encasements 10 are made of any polymer or composites, thereof. Moreover, in certain other embodiments of the present subject matter, the thickness of the encasement layers forming the coupling-face and / or non- coupling-face, is more than 1mm.

[0063] Lastly, in many of the embodiments of the present subject matter, the magnetic units 8 are formed by a plurality of segmented distinct pieces / units / segments / elements (not shown), made of any suitable material such as by, a unitary-composition, or, a composite, selected from the various magnetic materials as defined above, that operate in tandem in order to provide desired enhanced magnetic polarity on the coupling-face of each of the encasements. It would also be apparent to a person skilled in the art that, in case of encasement process of such segmented magnetic units, the same polymer used for encasements, or any other suitable material, may be employed as a filler, in order to fill the gaps / spaces between these segmented pieces of a magnetic unit.

[0064] As illustrated in FIG. 3 of the present subject matter, a magnetic coupling mechanism for an article 9, in a cross-sectional front-view.

[0065] In this embodiment, as illustrated in FIG. 3, the primary variation compared to that, of the embodiment as illustrated in Fig.2b is that, the fabric / material of the article 9 has an opening for the non-coupling-face. In other words, in FIG. 3 the fabric / material of the article is exactly as thick as the total thickness of the encasement, allowing for the coupling-face and non-coupling-face of the encasement to be in an open revealed state, by a front aperture and a rear aperture within the material / fabric of the article 9. Unlike, in the case of FIG. 2b, where the fabric / material of the article 9 has a portion of its layers concealing the non-coupling-face of each of the encasements, from being revealed openly. There in case of the illustration of embodiment as in FIG. 2b, only one-side of the fabric, that is the front-side has the aperture, while the rear-side of the fabric / material of the body of the article is unaltered.

[0066] As illustrated in FIG. 4 of the present subject matter, a magnetic coupling mechanism for an article 9, from FIG. 1 is depicted here, with a cross-sectional view.

[0067] Specifically, FIG. 4a and 4b, illustrate, a portion of the article 9 and a cross-sectional perspective-view of the portion of article 9 having a single encasement 10, from a pair of encasements, respectively. Here, the cross-sectional view as seen in Fig.4b. of the encasement 10, clearly illustrates one of the magnetic units 8, from the pair of magnetic units with opposite polarity. More importantly, this figure illustrates that the fabric / material of the body of the article 9, around the encasement 10 is formed by two distinct layers of fabric / material of the article 9. Further, these distinct layers of article 9, form an appropriately shaped aperture / recess / receptacle / cavity, in order for it to receive the encasement 10. Further, it can be seen here that, the encasement 10 has a stepped side-profile, wherein the coupling-face has less cross-sectional area, as compared to, the non-coupling-face of the encasement 10.

[0068] Furthermore, it should be noted that here in Fig. 4a, 4b and 4c, the layer of the fabric / material of the article 9, towards the coupling-face of the encasement has an aperturematching the step of the encasement 10, and, the layer of the fabric / material of the body of the article 9, towards the non-coupling-face of the encasement does not have any apertures. Specifically, FIG. 4c illustrates a cross-sectional front-view of a single encasement 10, from a pair of encasements. Further, here it can be seen that the portion and layer of fabric / material of the article 9 having the aperture, forms a lip-area over the step-area of the encasement 10, as disclosed in description above. Within the illustrations of embodiments, as depicted in Fig.4, this lip-area is employed for the purposes of permanent coupling, of each of the encasements 10 and 20, with its respective aperture / recess / receptacle on the article 9, by the manufacturer.

[0069] As illustrated in Fig. 4d and 4e, an opposite counterpart encasement 20, that is also received within the aperture / receptacle / recess provided on the other end of the article 9, in a similar fashion as encasement 10 is described and illustrated in Fig. 4a, 4b and 4c. Further, here the magnetic coupling mechanism is seen in operation, as the two encasements 10 and 20, encasing the pair of magnetic units 9 are coupling two ends of the article 9 with each other. Further, it can be clearly seen in Fig. 4e, that the magnetic coupling mechanism provides a medium-free coupling between the two-ends of the fabric / material of the article 9. Due to this, the chances of the fabric / material of a body of the article 9, from rubbing against each other or with respect to each other, is significantly minimized, which in-turn prevents overall wear / tear of the material / fabric of the body, when the encasements 10 and 20 make contact with each other, during operation.

[0070] Lastly, in some embodiments of the present subject matter, the encasements 10 have any custom shape / profile, other than the shape depicted here in FIG. 4. Furthermore, in some embodiments of the present subject matter, the encasements 10 are made of any polymer or composites, thereof. Moreover, in certain other embodiments of the present subject matter, the thickness of the encasement layers forming the coupling-face and / or non- coupling-face, is more than 1mm. This thickness may further vary in still other embodiments, based on the magnetic force of the magnetic units, purpose of use, area of application, other physical / safety parameters and / or considerations.

[0071] As illustrated in FIG. 5 of the present subject matter, a magnetic coupling mechanism for an article 9, in a perspective view.

[0072] Specifically, this figure 5a. depicts only a singular exemplary encasement 10, wherein the encasement has a coupling-face and a non-coupling-face. In that, the coupling-face of this encasement 10 has interlocking surface augmentations, that form a perfect puzzle-piece fit with respect to other interlocking surface augmentations, that are present on the couplingface of the counter-part encasement, or, the other encasement 20, that forms a pair with this encasement 10. The interlocking surface augmentations, shown form a plateau 6 and a valley 7, on the coupling-face of the encasement 10. Further, in this embodiment, a unique identification / logo 5 of the manufacturer maybe imprinted through methods, such as, heat- printing / indenting / embossing / debossing / branding, on the coupling-face of both the encasements, such as illustrated in FIG. 5a.

[0073] Further, in FIG. 5b, illustrates a magnetic coupling mechanism for an article 9, in a cross-sectional perspective-view.

[0074] Specifically, in this figure 5b. the interlocking surface augmentations, are seen in action. As, during operation, the pair of encasements 10 and 20, respectively come togetherin order to couple with each other, as per a user's desire. Here the encasement 10 has the interlocking surface augmentations 6 and 7, respectively. Whereas, the encasement 20 has the interlocking surface augmentations 4 and 3, respectively. Further, both the encasements 10 and 20, each have a magnetic unit 8, with an opposite polarity, with respect to the other. Hence, the coupling-faces, are attracted towards each other, as the magnetic units apply a linear mutually-attractive force on the pair of encasements, towards each other. After the encasements couple it is depicted within the cross-sectional view provided that, the interlocking surface augmentations, 7-4 and 6-3, form puzzle-piece fit with each other, in order to restrict any kind of lateral force / moment, within perpendicular to the magnetic attraction. This restriction ensures that the magnetic coupling mechanism, never slides-off in a lateral direction, even under extreme circumstances.
