说明书全文 | The present invention applies to a device to keep parts of garments, undergarments, or any other accessory closed, arranged, fastened, and adjusted. Each part is equipped with a magnetic component suitable to interact with the magnetic component of the other part of garment. The invention also applies to corresponding garments, undergarments, and accessories. The invention has a particularly significant, nonexclusive application in the field of lingerie, for example: bras, garter belts, corsets. The device also applies to: hats, foldable portfolios, briefcases, bookbags, bags, hoods, necklaces, bracelets, adjustable watches, splints, medical belts, sweat belts, sporting instruments (weightlifting belts), bathing suits, diving belts, sport or walking shoes that can all use the magnetic components. The magnetic or ferromagnetic components can be divided into two categories: soft materials which magnetizes easily (they have high permeability and can sometimes be demagnitized), and hard materials that, because of strong residual magnetization, are used as permanent magnets. From this point forward the term magnetic component is used indifferently to denote soft materials or hard materials that form permanent magnets. Let us note that a permanent magnet can be natural as well as artificial. As an artificial magnet, structure varies. Artificial magnets can also be formed more easily, and they can be adapted to the desired uses in order to make them have a stable magnetization that is more intense and more durable than that of natural magnets. The next paragraph discusses the polarities or poles of the magnets that make up the magnetic components. Every magnet has two opposite portions called poles, namely a positive pole or North Pole (tendency to orient towards north) and a negative pole or South Pole(tendency to orient towards south). In the process of their use in clothing, undergarments or accessories, the magnets of the system in one part of clothing are brought to interact with the magnets of the system in the other part by one of their opposite poles. To simplify, hereafter the magnet whose pole is arranged to interact with the magnet on the other part will be called a positive magnet, and the magnet with the negative pole, a negative magnet. Devices are available to connect, to adjust and/or to fasten parts of clothing, such as dresses, bras or accessories such as shoes or belts. Maintaing contact between, adjusting or closing clothing, shoes, or any other accessory is traditionally carried out by using buttons with buttonholes, buttons with stirrups, snap fasteners, clasps, laces, eyelets, zippers or any other means of fastening or closing known under the brandname “Velcro®”. Such devices, which have been in use for a long time, present a stationary means of fastening, made up of male and female components that connect with each other and can have inconveniences. These traditional devices are not easily adjustable, forcing the user to re-sew or remove components to get a good fit. Additionally, their adjustment will always require alteration from the user, which can be difficult for some, such as handicapped people, pregnant women, the elderly or children. There are also belts with a magnetic closing device (U.S. Pat. No. 5,307,582) which allow minimal adjustment. However, this device is not optimized and is complicated and expensive to use. There is also a system (FR-A-2.492.938) for closing clothing made up of magnetic components fixed on rigid material, spaced out along the edges of 2 flexible ribbons. Similarly, document FR-A-2.005.580 describes a closing system for a ski boot equipped with a magnetic safety device that prevents involuntary opening. Generally, all these magnet systems only make it possible to associate two parts, male and female components, which are in a predetermined position without the possibility of instantly modifying the position. Devices are also available (WO/0013328) which allow for a fastening that can be modified, and these devices are generally satisfactory. But even these can still be improved. The magnetic components in these devices are made of metal that can be very heavy and uncomfortable. They may also generate a magnetic field of high intensity that still needs to be optimized. In particular for underclothing, it is understood that a heavy bra-strap can be uncomfortable and/or a magnetic field that is too strong can present disadvantages, for example; possibly disrupting the function of electronic devices that are placed near the magnet, like a pacemaker. The present invention aims to solve these disadvantages by proposing a device for fastening parts of clothing, underclothing or accessories, between magnets that fulfill, better than preceding devices, the requirements of optimizing the weight and the force of the magnetic field. It enables easier opening and/or closing of clothing, for example from a distance and/or awkward position, which allows for a better fit and greater comfort for the user. Implementation and also the maintenance of the device (washing for example) are facilitated. People handicapped either by their condition or their environment, or those that have to move a lot also benefit from the simple closing system invention that is reliable, inexpensive, and easy to use. To this end, the present invention proposes a device to maintain in contact, regulate, adjust or close parts of clothing, undergarments such as bras and garter belts, or any other accessory. This device is made up of a first part that has a magnetic component and a second part that has a second magnetic component making it possible to fasten, regulate, adjust or close clothing, the undergarment or the accessory when one of the aforesaid first and second parts is used to interact with the other part. Each magnetic component is composed of at least two groups each one equipped with at least one magnet. The groups of the same magnetic component are fixed directly or indirectly on the same support and/or with each other, and are specialized to interact with the groups of opposing signs of the other magnetic component. In advantageous methods of assembly, one can turn to one of the following provisions:
The first established layer being situated from side opposite to the other magnetic component;
Advantageously the bra consists of “double parallel sheaths”, which enable it to adapt to the activities and the movements of the user. Additional support is consequently obtained with closing while allowing, in particular for big busts, a better distribution of the magnetic mass and/or traction. The double sheath indeed allows a greater range of adjustment thanks to the mobility of the magnets. Also advantageously, the bra consists of a set of double long sheaths that allows for a highly reliable closing with two magnets per magnetic component. In an assembly method, the bra consists of removable and adjustable straps, and/or the adjustment is in the front which makes it possible to bring the breasts closer together. Advantageously, the closing is with a triangular sheath, which allows for a more precise adjustment and closing thanks to horizontal and vertical displacements of the magnet or magnetic component in the sheath. Horizontal displacement, from right to left, undoubtedly makes it possible to bring the breasts closer or move them apart thus being able to offer more or less uplift, vertical displacement, from top to bottom, allows the bra to adjust according to the task. When the magnet or the magnetic component is drawn to the top, the bra is in a sport position. When the magnet or the magnetic component is drawn to the bottom, the bra is in a position for relaxation. If medium support is required, one adjusts the magnet or the magnetic component to the middle of the bra. The triangular shape of the sheath also makes it possible to personalize the bra by placing the logo of the brand on the sheath. Still advantageously, the bra has a back in the shape of “y”, the straps being removable or not, or the bra is part of the top of a one or two-piece swimsuit. The invention also proposes a garter belt provided with a device as described before, characterized in that the low-grip consists of two mobile magnetic components in a sheath, which each one can be separated by a seam. Closing is done through connecting the two magnetic components at the bottom. It also proposes a guepiere provided with a device as specified above, characterized in that it consists of at least two sheaths, and advantageously five, each one composed of two magnetic components, a fixed and a mobile, separated by a seam. Each sheath passes through a loop of rectangular shape a few millimeters larger than the sheath, and then is closed. According to the invention, an accessory is a watch equipped with a device as described before. It consists of a watchband made up of two sheaths which each pass through a central loop. Each sheath contains two magnetic components, a fixed and a mobile. The invention also concerns a cap equipped with a device consisting of, an adjustment strap which contains two magnetic components, a fixed and a mobile. The accessory can also be a sport-shoe equipped with the device. It includes four sheaths in which each one passes through a loop, each sheath contains two magnetic components- a fixed and a mobile. Advantageously, the shoe contains a tightening tongue and the closing of the shoe contains a part of the device, the mentioned tongue consisting of a magnet or a ferrogmagnetic element of soft mobile material and put together in order to open an close the degree of tightening of the tongue. Also advantageously, the shoe contains two tightening tongues opposing the sheath and the magnet or the ferromagnetic element of soft and sliding lining. The invention proposes as well a bag characterized which contains at least one device with a sheath which allows for the tightening/loosening of the opening of the sac and/or the more or less tightened positioning of a volume flap. The invention proposes as well a skirt with a belt equipped with two sheaths with magnets on a ferromagnetic element in soft sliding material, put together for cooperating with a magnetic component fixed on the opposing side. The invention will be better understood after reading the description which follows on assembly methods given through non-restrictive examples. The description refers to the drawings which accompany it in which: From now on one will use if possible the same reference numbers to indicate the same or similar components. The magnets used in the assembly methods of the invention described in more detail here preferably contain Neodyne Fer compressed Boron of density 7.3 to 7.5 g/cm3, the coating of the magnet can be obtained through an alloy containing nickel, zinc or tin and copper. One of the difficulties of this invention was guaranteeing the correct operation of the magnets over time. Taking into account the aging of magnets (which have an asymptotic limit) when they are subjected to washing and significant temperature, out-of-date magnets are used. This problem was fixed in the invention by using the advantageous manufacturing process of magnetic materials containing usable rare metals that follows. The various raw materials for the alloy are first mixed with a high degree of accuracy, under a vacuum or under inert gas. For example, one mixes the components according to following preparations in mass of Neodymium iron boron: 33% to 35% of Neodymium, 64 to 66% iron and 1,1% to 1,3% of boron. The primary product can be obtained by fusing the components or reducing in a calciothermic way, for example: towards 1300° C. starting from a fluorinated compound iron NdFe and chloride FeC13 (NdF3+Ca+FeC13—<(NdFe)+CaCIF+CaFe2). The raw material particles are crushed until they react to very precise tolerances (grains of about 1 micron). Then, the products are stamped by forcing a powerful magnetic field to direct the metal particles. Finally, the components are sintered in a special furnace under a vacuum with 1050° C., or under argon. After a fast cooling, temperatures are raised (600 to 900° C.) before finishing the cycle with a fast hardening. Finishings are then carried out with flash manufacturing machines or with machines equipped with diamond tools because the end product is very resistant. Among other usable materials, one notes the Samarium Cobalt (SmCo5, SmCo17) and other types of Neodymium Iron Boron (Nd2F14B), which are magnetic materials containing rare metals that are highly effective. In order to avoid oxidation, the end product in Neodymium Iron Boron is galvanized once (Ni, Sn or Zn) or three times over (Ni+Cu+Ni) (Sn+Cu+Sn) or (Zn+Cu+Zn) or advantageously Ni+Ni+Au ou Ni+Au. In the case Nickel or Gold galvanisation, one retains for example depths of 0,01 mm of Nickel and 0,001 mm of Gold. The magnets can be covered one by one with a protective layer also obtained through the galvanization of nickel/copper or nickel/epoxy, or any other galvanization which will prevent the magnets from rusting. These magnetic materials of higher quality are used in cases where one needs a very high magnetic force and have five times less space than with hard ferrite magnets of the same magnetic power. According to an assembly method of the invention, the first magnetic component 4 consists of two magnets stuck together, namely a first positive magnet 4′ and one first negative magnet 4″, and is mobile inside the sheath which consists of a double band of 1 cm of width out of fabric. Device 1 includes one second part 5 comprising a second magnetic component 6 made up of two magnets, namely a second positive magnet 6″ and a second negative magnet 6′, which will be able to interact with the first magnets of opposite signs 4′ and 4″. As shown in reference to the arrows 7, the first magnetic component 4 whose width is smaller than the width of the sheath, will be able to slide in the aforementioned sheath 3 between different positions, with a multitude of adjustments being possible. Taking into account that two polarities are present on the same magnetic component, the fastening between the parts is more solid, and weight and magnetic fields are equal, at the same time more extreme and easier to demolish, than with unipolar magnets. The magnets of each magnetic component are fixed for example by joining them to a support (not shown), that is flexible, for example made out of plastic material, which allows them to link to each other according to a preferred assembly method of the invention. Shown in These two sheaths 9 and 10 respectively, belong to a first and second part of the device 8 to which they are fastened. Sheaths 9 and 10 each include a magnetic component 11 and 12, each one made up of two magnets of opposite polarities, glued to a support (not shown), namely and respectively a positive magnet 11′, 12″ and a negative magnet 11′, 12′, the two components being specialized to interact one with the other, to allow a double fastening, which is for example beneficial in certain assembling methods of belts. FIG. (1c) shows a third assembly method of the device 13. Device 13 consists of a first part 14 made up of two sheaths 15 and 16 coupled top to bottom with one another, containing two identical magnetic components 17, the aforementioned magnetic components each one made up of three magnets, namely two positive magnets 17′ and 17″′ framing a negative magnet 17″, suitable to interact with two magnetic components 18 pertaining to a second part 19 of the device, and each one made up also of three magnets, namely a positive magnet 18″ framed by two negative magnets 18′ and 18″. The second part 19 is formed from two identical small pockets 20, remotely opposed one from the other, and fixed at one or more points in the clothing, for example out of fabric, suitable to be laid out opposite respectively to the two sheaths 15 and 16. The magnetic components 18 are fixed here, for example by gluing and/or simply blocking a portion of the small pocket at its end, for example via seams 21. Device 22 includes one second part 27 consisting of a strip forming two small pockets 28 equipped with two central parts 29, whose two magnetic components inside 30 are blocked. Here, each magnetic component respectively includes a positive magnet 25′, 30″ and a negative magnet 25″, 30′, suitable to react with each other, according to their respective polarities. In this assembly method, the magnets of the same magnetic component are fixed rigidly with each other. Looking at In the assembly method shown in reference to Components 33 have larger dimensions in length compared to their width and/or their thickness, for example more than five times, and particularly more than ten times larger. In this assembly method, to assure the fastening, the two magnetic components 35 can for example be on the same strip 36, which passes through slit 37, ending at the end 38 of other strip 39, of the closing. The two magnetic components are separated between them by seam 40. In this assembly method, the magnetic components could be replaced by two identical magnets. The system allows a double sliding motion according to the magnetic components that interact, (cf This system also allows a second type of closing, which is larger, and occurs only when the two sheaths are put end to end (arrow 48). The The magnet or magnetic component correspondent of the other part is identical but reversed in polarity, which makes it possible to fix the magnets in a top-to-bottom way and to obtain a complete rectangle (cf. 3b). The unit thus obtained can be conceived of only one part by moulding or fitting, which avoids the eventual problems of brittleness from gluing; The A magnetic component is an ensemble of magnets assembled through magnetic contact or by gluing in order to form a “block” of magnets. These magnets are generally parallelepidedic and are glued by section (the least significant surface of the parallelepide) . The unit obtained is not very stable. When they are not fixed with each other by more rigid means, a movement or a shock leads the magnets to position themselves one against the other across the greatest surface of the parallelepiped. To preserve flexibility and stabilize the block, a manufacturing process can be implemented and is described below. According to a favourable assembly method the invention, the magnets are assembled by side contact (on the smallest side of the magnet) and to form a multipolar block 62 (cf. Magnets 63′ are kept up between each other through magnetic contact and a special known adhesive 64, which adheres to the surface of magnets. Advantageously, preferably a support or fabric 65, for example made up of a groundwork and/or plastic film (cf. In this manner,one obtains an assembly made up of three layers; firstly, magnets 63 secondly adhesive 66 and thirdly, support 65. Everything permits a block-joint. As a specification, the magnetic component or the block can have 2,4,6 magnets or as many as necessary. The block-joint has a significant advantage because it will be able to adapt to rounded shapes or bodies 67 (cf. It also allows the magnets to stay in contact. Advantageously when the magnets are laid out vertically, the bending of the blocks is vertical. One uses in this case rectangled parallelepipedic shaped magnets placed vertically, each magnet stuck (through magnetic contact) to the next magnet by the longest side; the magnets placed end-to-end make up a vertical flexible block; it is the most commonly used method to assemble FIGS. 4 to 4d show two complementary magnetic components 70 and 71, usable with the invention, which are very powerful because they generate an effect which can be compared to that of a suction cup. The two components present the characteristics specific to the magnets previously used for specifically exploiting different magnetic fields. The assembly method follows: It is composed of three parts: a) the large base disc 72 b) small disc 73 c) ring 74. The magnetic component 71 is made up of a flat and circular magnet i.e. the large basic disc 72 to which one adds in his center a smaller circular magnet, or small disc 73, being able to penetrate in the ring 74 which is opposite. As a suggestion, for disc 72 with 18 mm and height of 2 mm, the small disc 73 will be 5 mm in diameter with a height of 1,5 mm and the ring 74 will have an external diameter of 18 mm, an internal diameter hole 75 of 9 mm for a height of 2 mm, the proportions vary according to power needed. Power is a function of the size of magnets used, the bigger the magnet the more important power is. The magnetic field of the suction cup is really specific, it acts from the interaction between the fields of the magnets used. Large disc 72 is a bipolar disc, magnetized in an axial way (northern above and south below). Small disc 73 is a bipolar disc, magnetized in an axial way (northern below and south on-top), but it can also be reversed, meaning that the large disc and small disc can be magnitized similarly. Ring 74 is hollow in its center, this hole gives the ring a specific magnetic field (cf arrows 76). The ensemble of these magnetic fields is represented with Inflection is possible in three ways: horizontal (feature stopped 79 on This block also has the characteristic to present very round external stopping. It makes it possible to exploit a new principle of inflection based on a possibility of diagonal torsion joining a number of shapes more significant than the two magnetic blocks or components cited previously. This arrangement allows the bra to adapt to the activities and movements of the user. She (the user) is ensured of additional support at the time of closing and allows a distribution of pressure due to fastening. In addition, from the mobility of the magnets the double sheaths allow for a diversity of adjustments 86, 87 and 88 (cf An attribute of the bra with double sheaths (see Moreover, this device makes it possible to fasten past the manufacturers predetermined limits. Finally, it adds additional support because when the fixed limits of the sheath are passed, the fixed magnet 44 does not come into contact with the mobile magnet 46 and will clamp down on the second fixed magnet(cf appears 2e). The magnetic components or magnets 93 in each of the two branches 94 of the “y” are mobile ( In an assembly method, the sheath system 97 is known as “elevator” ( A vertical and dorsal base joint 98 contain a magnetic component or magnet. The left and right-hand side straps have a magnetic component or a magnet at their ends 99. The straps join with the interior side of the base joint (arrow 100- A rubber band (not shown) placed in the base joint and fixed to the magnet of the previous makes it possible to slide and in this manner to move the magnet from the joint base to which the straps were joined, which makes it possible to simultaneously tighten the right and the left strap. Bra 102 “with frontal closing and adjustment” is represented in Indeed, the bra market answers in a traditional way to respond to customers who act according to their body types. There are several types of figures: breasts that are far from each other, an intermediate position, and finally breasts that are closer to each other. Today, brands share customers according to their choice in cup positioning (spaced apart, at a medium distance, brought closer together). Thus a customer who specifically wishes to bring her breasts closer together is obliged to change brands. The system described makes it possible to close then adjust. Thanks to an assembly method, it is possible to satisfy the customers described above as well as the customer who wishes to change the aspect of her chest (for example to give the effect of a plunging neckline) Frontal closing (cf The rectangular sheath also allows for precise adjusting and closing around the bust and that is thanks to a horizontal displacement of the magnet in the sheath. The triangular sheath 104 (cf. Vertical displacement, from top to bottom, allows for an adjustment according to the task; when one draws the magnet to the top, the bra is in sport position, when one draws the magnet 105 to the bottom, the bra is in a position for relaxation. If one wishes a “median” tightening, one adjusts the magnet in the medium. The triangular shape of the sheath also leaves room for personalizing the bra by placing the logo of the brand on the sheath. The straps are effectively completely removable by means of hooking 112 described once again in reference to This device answers the criteria mentioned above to which the following characteristic is added: A sheath 137 containing a magnet 138 comes to superimpose on the sheath 139 containing a magnetic element or a magnet 140 with a return 136 equipped with magnet 141, which increases the magnetic power and can act as ornament, for example, by adding lace on the aforementioned sheath of reinforcement. This sheath can also display the logo of the brand. The garter belt of It is placed and removed more easily than the traditional system. Replacing the low-grip uses two mobile magnetic components or magnets 151 in a sheath 152, which can be separated by a seam 153. Closing on the stocking happens through the locking of the two magnets or components. The system of height adjustment can be done with a fixed magnet or magnetic component 154 and one mobile 155, which slides in a sheath 156. The magnet or variable component allows an adaptation to the person's measurements but especially, answers and adapts to the various types of figures. The guepiere (not shown) can consist of five sheaths each one made up of two fixed magnetic components or magnets, and a mobile separated by a seam. Each sheath passes through a rectangular loop a few millimetres larger than the size of the sheath, then the sheath is closed on itself. From hereafter and in a nonrestrictive way, is a description of various methods of rectangular sheaths usable with the invention, in reference to One then stitches 171 on the two long sides 172 and the bottom of the pocket 173 obtained. Two bands of celluloid rhodoid 174 2 mm broad and glued are placed along the large sides of the sheath. The sheath is then reversed (arrow 175) then stitched in 176 to trap the two bands of celluloid rhodoid and to guide the movement of the magnet (not shown) in the sheath thus obtained 177. The contact surface of the sheath with the adjacent sheath can be covered with silicone 179, rubber or semi-adhesive matter, in order to increase adherence between the sheaths that are in contact. One thus slows down the movement of the sheaths and one increases the pulling force by creating a suction cup effect. Nylon 181 coats the inside 180 of the sheath to facilitate the movement of the magnetic component 182. The visible exterior 183 of the sheath is in covered jersey. The assembly can be done by stitching or welding (hot or by ultrasound) (arrow 184). The nylon and the jersey are assembled by using a heat sealing 185 to obtain a first part of sheath. The second part is made up of nylon in the interior which is covered with a layer 179 of silicone. According to the silicone reaction to the ultrasounds, this one will be applied before or after the welding. This sheath can have a specific shape, in order not to obstruct the mobility of the magnet in the sheath. The edges of this sheath can be reinforced with heat sealing on the sides.
The glue 188 presents different characteristics:
As an example, one can use a glue with a silicone base resistant at 250° C. The body of mold 190 posseses 2 slots or gutters 192 and 194. Gutter 192 has the form of the magnetic element 186 to obtain. Gutter 194 allows the insertion of flat element 193 of ferromagnetic material; or a lengthened parallelepedic form that the utility will be developed after. An intemediary element 191 is placed in a mold on the internal face of gutter 192. It plays an anti-adherent role, preventing the glue to adhere on the mold 190. Component 191 is for example formed from a plastic film, for example in polyethylene. Other mold assembly methods are possible. For example, in aluminum with a coating of a known material under the brand “Teflon®”, or a mold entirely in polyethylene. In this case, one can avoid the presence of film 191. One will now describe the fabrication of magnetic element 186, according to an assembly method of the invention. After having arranged the anti-adhering element 196 in gutter 192, one places different rows of magnets 189 that are thus naturally plated on the bottom of the gutter 194 thanks ot the magnetic attraction exercised by the element 193 aranged at the bottom of gutter 194. This placement allows for the avoidance of the deplacement of magnets 189 as the injection of the aforementioned glue 188. After having recovered the magnet rows 189 with glue 188, one places the support band 187 on the superior force of the layer of glue in this way formed. Then one comes to create the rounded off superior part of the band, and one can leave it to dry. The drying can occur naturally (in free air) having heard that a lightly humid environment facilitates the polynerisation of this glue, or by a forced method (oven, heating resistances, ventilation or any other system). The operation of the “casting” of the block magnets with the glue can make the underneath empty; in a free atmosphere or in all other conditions of temperature or pressure advantages. The The sheaths 202 and 202′ are in fine fabrics (for example of the order of 75 to 80 microns of thickness) supple, light and resistant so as to allow a maximum approach of surface elements 196 and 197. Although at first more complicated, this arrangement of magnets 198, 199, 198′ and 199′ present the following advantages:
The Here one uses magnets 186 and 187 in the form of square or rectangle parallelepides placed end to end in alternating negative and positive magnets of different thicknesses. More precisely, Surprisingly, this alternating of polarities allows a factor gain of 10 of the magnetic strength. The number of rows of magnets by row are not exhaustive and depend on the desired strength for a given application. The magnets can be placed either in a symmetric fashion or in a “check pattern” whatever the number of rows. As added information, for a magnetic element with two rows of for magnets each, with β=γ=3 mm, δ=0.5 mm, ε=1.5 mm, or α=1 mm and ε=6 mm, one gets
For an even volume of magnets, in relationship to the classic onfigurations (even thickness) the symmetric alternating allows for the increase of contact surfaces of a factor of 1.25 and of 1.33 for the alternating in check pattern. This organization of magnets 206, 207, 206′ and 207′ resents the same advantages as for the case of simple block lternation of FIGS. 15 are either:
To optimize the magnetic strength necessary for each application, one can therefore vary different parameters:
Here one sees the very large palette of solutions that the invention can present, particularly in certain types of applications. The magnetic component 212 is composed of one or several rows of magnets 214 that are glued, sodered, or otherwise fixed by the bias/cross of an element 218″ (double face adhesive for example, of a known type, to ferromagnetic elements 215 in soft material). The whole thing is fixed on a support for example supple in a plastic material, 217 with a known type of glue 218 as previously described. The block in this way constituted can be inserted in a sheath 219 of cloth of another material in which the block can deplace (long sheath) or be nearly fixed (short sheath). The magnetic component 213 is composed of several ferromagnetic elements 216 fixed on the support 217′ (for example in soft steel of type XC10 completed by a protection of steel plates against the oxidation/corrosion caused by washing) with the known type of glue 218′. This new block can equally be inserted into a sheath 220 of cloth or of another material, and to hem (long sheath) or be fixed (short sheath) on the inside. As added information, magnets 214 are of parallelipipede 6×3×1 mm arranged on two levels, components 215 are of parallelipipede 12×3×1 mm in soft steel treated for anti-corrosion of the same type which was described in reference to the support. The support is formed by a band in plastic material from 12 mm in width and 0,2 mm in thickness. The component band 212 to a width of 14 mm and a thickness of 3 mm. All these values correspond to a given application for a given use. The magnetic element 221 is composed of a simple alternating of magnets 225 and 226 of different thicknesses, fixed by an element 231″ (glue) to ferromagnetic elements 215 of the same thickness. The whole thing is fixed on a support 230 with a known type of glue 231. The block in this way constituted is complimentary with the magnetic element 221 and can slide or stay fixed in a sheath 233 in cloth or another material. Magnetic element 223 is composed of a double alternating of magnets 225 and 226 of differing thicknesses fixed to ferromagnetic elements 227 in soft material of a constant thickness. The magnetic component 224 is composed of a double alternating of ferromagnetic elements 228 and 229 of different thicknesses. The magnetic components 221, 222, 223, and 224 can be on one or several layers. For your information, one can use magnets 225 of a thickness of 1.5 mm, magnets 226 of thickness 0.5 mm, ferromagnetic complimentary components 228 and 229 of respective thicknesses of 0.5 mm and 1.5 mm, and components 227 of thickness 1 mm. Magnetic component 234 is composed of one or several magnets 236 that are fixed with one or several rows of ferromagnetic elements 237 in soft material for example soft steel. On one of the block ends in this manner constituted, one comes to glue, soder, or fix by another device 241, a ferromagnetic element in soft material 239 that the height is inferior to the thickness of the block in order to permit the complimentarily with element 235. Magnetic element 235 is composed of one or several rows of one or several ferromagnetic elements in soft material 238, soft steel, where one comes to glue, soder, or fix it by another device 242, on one of the ends, one or several ferromagnetic elements 240 that the height is superior to the thickness of the block in order to permit a complimentarily of form with component 234. The magnetic element 243 is composed of one or several rows of one or several magnets 236 fixed 5(s) with one or several rows of ferromagnetic elements 237. On the two extremeties of this block in this manner constituted, on comes to glue, soder, or fix by all other means 241 and 241′ of ferromagnetic elements 239 and 239′ that the height is inferior to the thickness of the block in order to permit the complimentarity with component 244. Magnetic element 244 is composed of one or several rows of one or several ferromagnetic elements, to fix by other means 242 and 242′, on the two ends, of ferromagnetic elements 240 and 240′ that the height is superior to the thickness of the block in order to permit the complimentarily with component 243. The two systems of magnetic closure of As added information the components 236, 237, 238 can be of thickness 1 mm and components 239, 239′, 240, 240′ can have a height of 1.6 mm. The ferromagnetic elements 237, 238, 239, 239′, 240, 240′ can be implemented in soft steal treated for anti-corrosion. The configuration of
In this context, one can adopt the following values:
This means that the total thickness of the system is T=1,6+2=3,6 mm instead of 4,5 mm without doubling the pieces and this with similar magnetic power. The different configurations of The quality of the guiding depends on the type of guides used (form of the section, size of the section, material used) and of the number of the piercings. In the configurations of As added information, using metallic guides (for example type iron string) allows for a more precise guiding of the magnetic component than using linen string for example. On the contrary, the linen string allows to better follow a complex contour like a part of the body. The choice is made in relation with the desired application. The block is therefore placed and fixed on a support (267) by gluing, sodering or other system of fixing 275. Support 267 can be rigid or supple according to the desired applications. Elements 269 and 269′ represent the piercings 270 and 270′ which allows the linear guiding of the magnetic component 279 with the strings or components of the round section 271 and 271′. The section of components 271 and 271′ can be square or of another form. Such an arrangement will allow to reduce the number of magnets and therefore the price at the same magnetic strength. Magnetic component 278 is composed of one or several rows of magnets 280 fixed on a suupport 282 with a known type of glue 281. The support 282 is embedded in the glue 281 and two or several piercings 283 are made in the superior part of the magnetic component 278. These piercings 283 allow the passage of guiding elements 284 that allow the translation of magnetic element 278. Guding elements 284 are fixed at the open sheath 285 by gluing, sodering, sewing, or other system. Magnetic element 278 is composed of several rows of magnets 280 fixed on a support 282′ with a known type of glue 281′. The magnetic component 278 is fixed on an open sheath 286 by gluing, sodering, sewing or other system. The same type of open sheaths with with added soft steel plates (idem The magnetic component 288 remains inserted in a short type of sheath 293 and remains fixed on the inside. The adjusting of the closure is not done by the sliding of the magnetic component as compared with the other but by direct positioning of a short magnetic component 288 on a long magnetic component 287. The number of magnets 289 per row of magnetic component 287 depends on the range of desired adjustment. The number of magnets 289 per row of magnetic component 288, in this manner that the number of rows depends on the necessary magnetic power. This method of adjustment can as well allow an adjustment of the magnetic power of the closing by positioning more or less magnets of the magnetic components 288 opposing the magnets of the magnetic component 287. The higher the number of the magnets in contact the higher is the magnetic power of the closing. In this case, the adjustment is done by sliding a magnetic component into the interior of its sheath. This type of sheath can therefore be open (idem The shoestrings are here replaced by the sheath 303 containing two blocks of articulated magnets 304 and 305. One 304 is mobile and slides on an electric circuit 306 (306′) placed in a sheath 303. This circuit consists of for example, glued contacts on a supple PVC film, which makes it possible to obtain a circuit which is easily adaptable due to its great suppleness. The other magnet 305 is fixed in the mentioned sheath. Six LEDs 308, 308′, where a light component 309 pierces the surfaces of the sheath, indicates the level of welding. They are fed by the above mentioned circuit 306. More precisely, it consists of two conductor strips 310 and 311 that are placed opposing each other and electrically isolated from each other by a support 312 (supple plastic sheet for example in rodhoide). Eaxh strip is attached to a bar opposing a battery 313 placed in the sole 314 of the shoe 300. Sheath 301 folds back when passing over a plastic loop 319 connected to the shoe for example by two elastic points (not shown) in order to make the mobile magnet 304 cooperate with the fixed magnet 303 place in opposition. When moving during the tightening action, the magnet 304 closes then opens different branches 315′ , 316′, 317′, . . . from circuit 306′ that turns on the LEDs 308′. Finally, an interrupter 318 (318′) of the circuit is provided and can be manually activated by the user. This circuit is fed by a small round battery 324 (commonly used for watches), linked to eight LEDs 325 (325′ son the double sketch) this time integrated not in the tongue itself but in the logo of the shoe and consists of, as in the case of The LEDs therefore turn on in reaction to the tightening. The sheath goes through a stem stitch loop, for example in translucid orange PVC, mobile in rotation, adjusted to the shoe. In this assembly method, the closure of the circuit in 325 (326′) can be executed not by an interrupter, but for example by a folding and clipping of the ends of the strips 310 and 311. This loop is therefore connected to the shoe by an elastic band 333 which, once the magnet is positioned, causes the tightening force, and the magnet 322 is fixed in the shoe, the magnet 333 moves while one pulls at the loop during the tightening. This magnet slides therefore through the electric circuti and lightens oup the diodes. So, this is a variation of the application in FIGS. 27 are views from an angle of a watch 340 with two sets of magnets 341 and 342 each set consisting of a fixed magnet 341′ and 342′ and another mobile magnet (341″, 342″) sliding along the length of two rails 343 made of strings of plastic material. To close the bracelet, one has to make the fixed magnet of one branch correspond with the mobile magnet of the other branch, the adjustment being therefore possible thankds to the translation of the mobile magnets (cf. The sheath contains four mobile magnets, three round magnets 355 and a magnet block 356 for example hallmarked for certain ones for a strip and rodhoide support 357, the sheath 358 of the sheath being for example in white nylon. The end of the sheath is fixed with the side, by the bias of the magnet block 356 that cooperates with a fixed magnet block in the shoe. Three other magnets interact with similar magnets fixed to the shoe. The sheath is in this manner maintained in position. To tighten, one has to pull on the tongue then one flattens the end of the sheath against the shoe in order to maintain the adjustments. In certain assembly methods one can as well plan two parallel sets of transversal tongues. In the belt, one of the components is fixed on one side and mobile on the other side of the belt. As it results from those preceding it, the present invention is not limited to the assembly methods more particularly described. On the contrary, it embraces all the alternatives in particular:
The magnets can be advantageously covered one by one with a protection layer resulting from the nickel/gold or nickel/nickel/gold galvanization that will avoid the rusting of the magnets thereby making the magnets hypo-allergenic. As one has seen, the described invention brings along numerous applications in different sectors, such as:
