Description

DEVICE FOR FASTENING OR FITTING BETWEEN PARTS OF CLOTHING OR UNDERWEAR SUCH AS A BRA.

The present invention relates to a device for maintaining in contact, fixing, adjusting or adjusting between them parts of clothing, underwear or other accessories, each part being provided with a magnetic element capable of cooperating. with the magnetic element of the other party. It also relates to the corresponding clothing, underwear and accessories.

It finds a particularly important application although not exclusive, in the field of corsetry, for example for bras, garter belts, basques, but also for caps, school bags, bags, backpack, suitcases, hoods, necklaces, adjustable watch straps, harnesses, for example medical belts, corsets, sweat belts, corsets, sports instruments (weight lifting belts), swimwear, diving belts, sports shoes or walking shoes, all using magnetic elements.

Magnetic or ferromagnetic elements can be divided into two categories: soft materials, which magnetize easily (high permeability and reversibly), and hard materials because of strong remanent magnetization, which are used as permanent magnets. In the following, the term magnetic element will be used to designate indifferently the soft materials or the hard materials which therefore form permanent magnets. Note that a permanent magnet can be a natural magnet as well as an artificial magnet. In this case, it can therefore be of very variable constitution. It can moreover be shaped in a simple manner, adapted to the desired uses so as to make it take with good stability a magnetization much more intense and more durable than that of natural magnets.

Subsequently, it will also be necessary to mention the polarities or poles of the magnet or magnets constituting the magnetic elements used.

Every magnet has two opposite portions called its poles, namely a positive pole or north pole (tendency to point towards the north) and a negative pole opposite to the south pole. By virtue of its arrangement in the clothing, the undergarment or the accessory, the magnet (s) of a magnetic element of one part is brought to cooperate with the magnet (s) of the magnetic element of the other part by one of its opposite portions. To simplify, we will call the magnet below, the portion arranged to cooperate with the other party, has the positive pole, a positive magnet, and the one with the negative pole, a negative magnet. Devices are already known for bringing parts of clothing into contact, adjusting and / or fixing them, such as dresses, bras or accessories, for example clothing accessories, such as shoes or belts. Maintaining in contact, adjusting, adjusting or closing a garment, a shoe, or any other accessory is thus traditionally carried out using button-buttonhole, button- stirrup, press button, clasp, lace, eyelet, zipper or even by means of attachment known under the brand Velcro® ". Such devices, known for some since antiquity, have removable fixing means , comprising male means and female means connectable to each other, which have drawbacks, these means are not easily adjustable, for example forcing the user to unstitch or dismantle elements to obtain the correct adjustment.

In addition, their adjustment will always require precise manual intervention by the user, which is sometimes difficult for some of them, such as the disabled, pregnant women, children or the elderly.

Belts with magnets are also known (US-A-5,307,582) which, this time, allow a certain adjustment. However, it is not optimized, while being complicated and costly to implement.

There is also known (FR-A-2,492,938) a garment closure system comprising magnetic elements of rigid material fixed spaced apart on the edges of two ribbons of flexible material.

Similarly, document FR-A-2,005,580 describes a ski boot closure provided with a magnetic safety device preventing its involuntary opening.

But generally speaking, all of these known systems using magnets only allow to associate two parts in a predetermined position of the male and female elements, without the possibility of modifying the location of these elements instantaneously. Finally, devices are known (WO / 0013328) which allow such an adjustment, and which are generally satisfactory. But these can still be improved. Indeed, the magnetic elements which are metallic, can in certain cases present an awkward weight and / or generate a magnetic field whose intensity can be further optimized.

Indeed, especially for underwear, we understand that the weight of a bra strap can be annoying and / or that a too strong magnetic field can have drawbacks, for example by risking disturbing electronic devices. that would be placed nearby, a pacemaker for example. The present invention aims to solve these drawbacks by proposing a device for fixing or adjusting parts of clothing, underwear or accessories therebetween, meeting better than those previously known the requirements of practice in particular in that it allows optimize the weight and the strength of the magnets used, in that it generates greater ease of opening and / or closing of the garment, for example at a distance and / or in a signaled manner, and this by allowing better fixation and greater comfort for the user.

The implementation, but also the maintenance (washing for example) are thus facilitated. The disabled by their condition or their environment or those who perform many movements, thus benefit, with the invention, a simple closure, reliable, inexpensive and easy to implement.

The magnets used in the embodiments of the invention more particularly. described here are preferably based on Néodyne Fer

Boron of density 7.3 to 7.5 g / cm3 compressed, the coating of the magnet can be obtained by an alloy based on nickel, zinc or tin and copper.

One of the difficulties of the present invention was to be able to guarantee the proper functioning of the magnets over time.

Taking into account the aging of magnets when they are subjected to high temperatures and washing, aging which gradually tends towards an asymptotic limit, aged magnets are therefore advantageously used.

An advantageous process for manufacturing rare earth magnetic materials usable with the invention is also and for example the following.

The different raw materials for alloy are first mixed with great precision, under vacuum or inert gas.

For example, the components are mixed according to the following preparations by mass of neodymium iron boron 33% to 35% of neodymium, 64 to 66% of iron and 1.1% to 1.3% of boron (Neodymium 35) or in a preferred embodiment of Neodymium said 45 composed of about 30% of Neodymium, 66% iron, and 4% of Mb + Ab + Tb + others.

The base material can be obtained by melting the constituents or by reduction in a calciothermal route, for example, around 1300 ° C. from a fluorinated compound NdFe and iron chloride FeC13

(NdF3 + Ca + FeC13 - <(NdFe) + CaCIF + CaFe2).

The raw material particles are crushed, until they meet very precise tolerances (grains of the order of 1 micron). Then, the products are matrices by imposing a strong magnetic field to direct the metallic particles.

Finally, the elements are sintered in special ovens under vacuum at 1050 ° C, or under argon. After rapid cooling, a return to high temperatures (600 to 900 ° C) is finally carried out, before ending the cycle by rapid quenching.

Finishing is then carried out with flash machining machines or with machines equipped with diamond tools because the final product is very resistant. Other usable materials include Samarium Cobalt (SmCo5, SmCol7) and other types of Neodymium Iron Boron (Nd2F14B), which are highly efficient rare earth magnetic materials.

In order to avoid the oxidation process, the final product in Neodymium Iron Boron is for example simply galvanized (Ni, Sn or Zn) or tripled

(Ni + Cu + Ni) (Sn + Cu + Sn) or (Zn + Cu + Zn) or advantageously Ni + Ni + Au or Ni + Au.

In the case of Nickel, Gold galvanization, thicknesses of the order of 0.01 mm of Nickel and 0.001 mm of Gold are used for example.

The magnets can, for their part, be advantageously covered one by one with a protective layer also obtained by nickel / copper or nickel / epoxy galvanization, or any other galvanization which will prevent the magnets from rusting.

These high quality magnetic materials are used in locations where a very high magnetic force is required and require five times less space than hard ferrite magnets, with the same magnetic power.

FIG. 1a shows a device 1 for maintaining in contact, adjusting, adjusting or closing parts of clothing, undergarment or any other accessory, comprising a first part 2, comprising at least one sheath 3 into which a first is introduced magnetic element 4. According to one embodiment of the invention, the first magnetic element 4 consists of two magnets bonded to each other, namely a first positive magnet 4 'and a first negative magnet 4'', and is movable inside the sheath which is for example constituted by a double strip 1 cm wide in fabric.

The device 1 further comprises a second part 5 comprising a second magnetic element 6 constituted by 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 with reference to arrows 7, the first magnetic element 4 which is of width smaller than the width of the sheath, will be able to slide in said sheath 3 between different positions, a multitude of adjustments being possible.

Given the two polarities present on the same magnetic element, the attachment of the parts between them is more solid, and, curiously at equal weight and magnetic fields, both stronger and easier to undo, than with unipolar magnets

The magnets of each magnetic element are fixed, for example, by bonding to a support (not shown), flexible, for example made of plastic material, which allows them to be articulated with one another according to an advantageous embodiment of the invention.

FIG. 1b shows a second embodiment of the device 8 according to the invention comprising two sleeves 9 and 10 in parallel, for example constituted by ducts or chutes made of fabric of the same width and greater length, said ducts being located or likely to be located opposite during the implementation of the device, to close or adjust two open parts of clothing.

These two sleeves 9 and 10 respectively belong to a first and a second device part 8 to which they are fixed.

The sleeves 9 and 10 each comprise a magnetic element 11 and 12 each consisting of two magnets of opposite polarities, bonded to a support (not shown), namely and respectively a positive magnet 11 ', 12' 'and a negative magnet 11' , 12 ', the two elements being able to interact with each other, to allow a double adjustment, which is for example advantageous in certain embodiments of clothing belts.

The figure shows a third embodiment of the device 13 according to the invention. The device 13 comprises on the one hand a first part 14 comprising two sheaths 15 and 16 joined head to tail to each other, containing two identical magnetic elements 17, said magnetic elements each consisting of three magnets, namely two magnets positive 17 'and 17''' framing a negative magnet 17 '', suitable for interacting with two magnetic elements 18 belonging to a second part 19 of the device according to the invention, and each also consisting of three magnets, namely a positive magnet 18 '' framed by two negative magnets 18 'and 18''. The second part 19 is here formed of two identical pockets 20, opposite, at a distance from each other, and fixed to one or more parts of clothing, for example of fabric, suitable for being arranged opposite respectively the two sleeves 15 and 16.

The magnetic elements 18 are fixed thereto, for example by gluing and / or simply by being blocked in a portion of the pocket at its end, for example by means of seams 21.

Figure Id shows another embodiment of a device 22 according to the invention comprising a first part 23 comprising two identical movable sleeves 24 themselves comprising two identical magnetic elements 25, adapted to move inside the sheath according to the arrows 26.

The device 22 further comprises a second part 27, for example constituted by a strip forming two pockets 28 provided with two central parts 29, inside which two magnetic elements 30 are locked.

Here, each magnetic element respectively comprises a positive magnet 25 ', 30''and a negative magnet 25'',30', capable of cooperating with each other respectively, according to their respective polarity. In this embodiment, the magnets of the same magnetic element are for example here rigidly fixed to each other. In view of Figures la to ld, it is understood that when the magnetic elements and therefore their respective magnets, are brought into action with one another and therefore to be joined through an air gap formed by the simple thicknesses and / or double sleeves or bands in which said elements are located, the sleeves themselves integral with a part of clothing, shoe or other accessory, will be able to be moved with said part of the garment relative to the other part of the garment itself integral with the second part, which will allow adjustment or adjustment by sliding the first magnetic element in the corresponding sheath (s).

In the embodiments shown with reference to Figures la to ld, the magnetic elements are symbolized in section in the form of a rectangular plate. In Figures 2a and 2b there is shown an undergarment consisting of a bra 31 provided at the rear to hang the bra of a device 32 comprising two magnetic elements 33 of identical parallelepiped shape, suitable for cooperating with each other . They are superimposed on the figure.

The elements 33 have larger dimensions in length relative to their width and / or thickness, for example more than five times, and in particular more than ten times larger.

FIG. 2c shows another embodiment of a bra 34 which comprises two magnetic elements 35 capable of cooperating with each other. In this embodiment, to further secure the attachment, the two magnetic elements 35 may for example be on the same tongue 36, which passes through a slot 37, formed in the end 38 of the other tongue 39 , closing. The two magnetic elements are separated from each other by a seam 40.

In this embodiment, the magnetic elements could be replaced by two identical magnets. Figures 2a and 2f show other embodiments with “double” magnetic elements on both sides, using sheaths.

Figure 2e shows a device 41 provided with two identical parallel sleeves 42. The sleeves are parallel in order to distribute the load-bearing mass and the traction exerted by the basque turn on the user's back. Each sheath 42 comprises at its end 43 a first non-sliding magnetic element 44, separated from the rest of the sheath, for example by a seam 42. The sheath comprises in its other part a second sliding magnetic element 46.

The system allows a double sliding according to the magnetic elements which cooperate, (cf figure 2nd arrow 47), which allows a better security because the closing rests on four magnets. In this case, an eccentric closure is obtained on the sides of the spine, which avoids direct impact on the latter.

But this system also allows a second, wider type of closure, which occurs when the two sleeves are placed end to end only (arrow 48). Figure 2f shows a device 50 with sheaths 51 and magnetic element 52, the sheaths forming the ends of the breast straps connected to the rest of the bra by elastic bands 53. In the embodiments 2e and 2f, the magnetic elements could be replaced by unipolar magnets.

FIGS. 3a and 3b show a first embodiment of the magnetic element 54, parallelepidic, of 1cm x 1cm for example, usable with the invention. In FIG. 3b, at least one magnet or flat magnetic element 55 of parallelepidic shape, is glued to another larger magnet 56 which can be of rectangular shape. A magnetic element 57 is then obtained on the staircase.

The magnet or corresponding magnetic element of the other part is identical but reversed in polarity, which allows the magnets to be fixed head-to-tail and to obtain a complete rectangle (see 3b). The assembly thus obtained can be designed in one piece by molding or adjustment, which avoids any problems of brittleness of bonding; FIG. 3c represents a device produced in a mode identical to the previous one, with the difference that the internal field 59 of the small magnet 60 is bevelled. A magnet 62 is then obtained in the form of a half dovetail. A magnetic element is a set of magnets assembled together by magnetic contact or by gluing to form a "block" of magnets. These magnets, generally parallelepided, are placed side by side (the smallest surface of the parallelepided). The assembly thus obtained is not very stable. Indeed, when they are not fixed to each other by more rigid means, a movement or a shock causes the magnets to be positioned one on the other by the larger surface of the parallelepiped.

To both maintain flexibility and stabilize the block, a manufacturing process of the type described below can be implemented. According to an advantageous embodiment of the invention, the magnets are assembled together by lateral contact (on the smallest side of the magnet) and to form a multipole block 62 (cf. fig.3d). The magnets 63 'are held together by magnetic contact and by a special adhesive 64 of known type, which adheres to the surface of the magnets. Advantageously, a support or canvas 65 is provided, for example consisting of a canvas and / or plastic film (cf. FIG. 3) glued to the underside of the magnets (glue in broken lines in FIG. 6b.

As a result, an assembly consisting of three layers is obtained; firstly, the magnets 63 secondly the glue 66 and thirdly the support 65.

The whole allows a block articulation. Note that the magnetic element or block can have 2, 4, 6 magnets or as many as necessary. The articulated block has an important advantage because it will in particular be able to adapt to rounded shapes or bodies 67 (cf. FIG. 3g).

It also allows the magnets to be kept in good condition. Advantageously when the magnets are arranged vertically, the bending of the blocks is vertical.

In this case, rectangular parallelepiped magnets are used, placed vertically, each magnet being glued (by magnetic contact) to the next magnet by the longest side; the magnets placed end to end therefore constitute a block vertically flexible. This is the embodiment more particularly reproduced in FIG. 3d.

Figures 3a and 3f show an alternating arrangement of positive and negative magnets bonded to a support (not shown) in a mode identical to the previous one. Magnets 68 and 69 are used here in the form of a shorter rectangle or of squares placed end to end in two or more rows. The block thus formed is therefore flexible vertically and horizontally.

FIGS. 4 to 4d show two complementary magnetic elements 70 and 71, usable with the invention, which are very effective, because they generate an effect which can be compared to that of a suction cup.

The two elements present the specific characteristics of the magnets used previously with specific fear of exploiting different magnetic fields. The shape of this assembly is the result of long work.

It consists of three parts: a) the large basic disc 72 b) the small disc 73 c) the ring 74.

The magnetic element 71 is composed of a flat and circular magnet, ie the large base disc 72 to which a smaller circular magnet 73 or small disc 73 can be added in its center, which can penetrate into the ring 74 which is opposite. As an indication, for an 18 mm disc 72 and a height of 2 mm, the small disc 73 will be 5 mm in diameter for a height of 1.5 mm and the ring 74 will have a diameter 18 mm outside, an inside diameter (hole 75) of 9 mm for a height of 2 mm. The proportions vary depending on the power required.

The power is a function of the size of the magnets used, the larger the magnet and the greater the power. The magnetic field of the suction cup is really specific, it is in fact the interaction between the fields of the magnets used. The large disc 72 is a bipolar disc, magnetized axially (north above and south below).

The small disc 73 is a bipolar disc, magnetized axially (north below and south above), but it can also be the reverse, large disc and small disc being then magnetized similarly.

The ring 74 is pierced in its center, this hole giving it a specific magnetic field (cf. arrows 76.

All of these magnetic fields are shown in fig. 4d and allows to precisely match the curves of the body or hard organs (bones). In Figures 4 to 4h, there is shown an arrangement of magnets 77,78, identical to that of the block of Figure 3f but this time, magnets of cylindrical shape are used.

Bending will therefore be possible here in three ways: horizontal (broken line 79 in fig.4e) vertical (broken line 80 in fig.4f or diagonal (broken line 81, 82 in fig. 4h). This block also has the distinction of having very rounded external edges. It makes it possible to exploit a new principle of flexion based on a possibility of diagonal torsion thus marrying a greater number of forms than the two blocks or magnetic elements mentioned above.

FIGS. 5a to 5b show a bra 83 provided with a device with parallel double sleeves 84 and 85.

This arrangement makes it possible to adapt to the user's activities and movements.

It provides additional security during closing and it allows, for generous breasts, to distribute the forces due to the hooking. The double sleeves also allow a variety of settings 86, 87 and 88 (see fig. 5d-e- f), due to the mobility of the magnets.

The bra with double sleeves (see also fig. 2e) has the particularity of ensuring a very reliable closure (more reliable than with a single magnet). The two added sheaths allow an adjustment length twice that of the single sheath bra. In addition, this device makes it possible to accept a closure on a size that exceeds the shapes initially planned by the manufacturer. Finally, it provides additional security because when the limits fixed by the sheath are exceeded, the fixed magnet 44 leaves contact with the mobile magnet 46 and goes to rest on the second fixed magnet (cf. FIG. 2e). There is shown in Figures 6a to 6f another embodiment of bras 90 with a sheath system in "y", that is to say comprising a back strap 91 in the form of "y" whose l base 92 can be either rounded (fig. 6a) or straight (fig. 6b).

The magnetic elements or magnets 93 in each of the two branches 94 of the "y" are mobile (fig.6c-d) and can be closed by sliding and pulling with two magnetic elements or fixed magnets 95 (fig.6c-d) contained in the straps 96 of the bra. This system usually involves a frontal closure or sometimes under the arm.

In one embodiment, the sheath system 97 is said to be an “elevator” (FIG. 6e).

A vertical and dorsal common trunk 98 contains a magnetic element or a magnet. The left and right shoulder straps at their ends each contain a magnetic element or a magnet 99 each. The shoulder straps are attached to the common trunk on the inside (arrow 100 - fig.βf) or outside (arrow 101) side at the convenience of the user.

An elastic band (not shown) placed in the common trunk and fixed to the magnet of the latter makes it possible to slide and thus tow the magnet of the common trunk to which the straps are attached, which allows the straight strap to be stretched simultaneously and the left strap.

The bra 102 "with closure and face adjustment" is shown in FIGS. 7 ab. It allows not only a closure but also a reconciliation of the cups 103 (see fig. 7d) and there even an innovative adjustment possible thanks to the triangular sheath 104 (cf. fig. 7c) described below. Indeed, the bra market responds in a traditional way to the approach of customers who react according to their morphology.

There are thus several cases of figures: the breasts distant from each other, an intermediate position and finally the breasts close to each other.

Today, the brands share this clientele according to the choice of positioning of the cups (spaced cups, cups in the middle, close cups). Thus, a client who wishes to bring her breasts close to her on an ad hoc basis is generally obliged to change the brand of bra. The system described here allows you to close and then adjust.

Therefore, thanks to an embodiment of the invention, it is possible to satisfy the clients described above as well as the client who wishes to change the appearance of her breast (for example to give the effect of a plunging neckline)

The front closure (cf. FIG. 7c), with sheath, the shape of which extends in length and in width, will allow this closure with several types of sheath and is thus possible.

The rectangular-shaped sheath thus allows precise adjustment and closing according to the turn of the Basque and this thanks to a horizontal displacement of the magnet in the sheath.

The sheath 104 of triangular shape (cf. fig. 7c) allows an additional adjustment of the bra and this thanks to a displacement horizontal and vertical of the magnetic element or magnet 105 in the sheath. The horizontal displacement, from right to left, then makes it possible to bring the breasts closer or further apart, here again making it possible to offer a more or less plump neckline.

The vertical movement, from top to bottom, allows for adjustment according to the effort; when the magnet is pulled up, the bra is in the sport position, when the magnet 105 is pulled down, the bra is in the relaxed position.

If you want a "median" tightening, you adjust the magnet in the middle. The triangular shape of the sheath also allows, for example, to personalize the bra by adapting the brand logo to this sheath.

Figures 7e to 7h illustrate additional adjustment modes, this time on the shoulder straps 106 and / or on the rear part 107 of the bra 108, which can be combined with the adjustment modes corresponding to those illustrated with reference to Figure 7c.

FIGS. 7g and 7h simply illustrate the use of a magnet 109 in the form of pellets to do this, one magnetic element of which is fixed and the other mobile in a sheath 110 secured to the strap and / or to the rear branch 111 of the bra 108. Advantageously, the straps are completely removable by means of hooks 112 of the type described once again with reference to FIGS. 7g and 7h. More specifically, the suspenders whose ends are made of rigid nylon, pass between the cap 113 on the inside and a sewn fabric 114.

FIG. 8a shows a bra S of the type described above with suspenders B and belt C, the two ends E of which are either closed by a device of the type described in FIGS. 1, or by a device with three magnets, namely the magnets or magnetic elements Ai, A ₂ , A ₃ for example rectangular, flat, placed in the same sheath F which allows a snake configuration, folded in double V, the magnets being in opposition to allow an optimized and reproducible adjustment, a times the magnets locked in position in the sheath F for example by a stitch. Figures 9a to 9h illustrate a bra 115 with removable and adjustable straps 116 according to other embodiments of the invention, and to remove and adjust the straps to the right size, to cross the straps in the back (fig.f) or on the chest (fig.9e) of the user and this alone or in combination with the adjustment modes as described with reference to Figures 2.

FIG. 10a shows a watch strap 117 comprising a device consisting of two sheaths 118, 119 which each pass through a central loop 120, each of the sheaths containing two magnetic or magnet elements, a fixed 121 and a mobile 122. This device makes it possible to fix and adjust the watch according to the mode of the invention more particularly described.

FIG. 10b describes a wrist case 123 which passes through a loop 124 secured to the watch. This scabbard again contains a magnetic element or a fixed magnet 124 and a magnetic element or a movable magnet 125. The sheath folds back on itself to lock the assembly.

FIG. 10c shows a sheath 126 comprising a fixed magnet 127 and a movable magnet 128 which passes through a half-bracelet 129 terminated by a loop. The closure is the same as before.

FIG. 10d describes two sheaths 130 one containing a fixed magnet or magnetic element 131, the other a mobile magnet or mobile magnetic element 132 in a sheath according to one embodiment of the invention.

Figures 11a and 11b show a bra 133 comprising a sheath 134 with return 135 and reinforcement 136.

This device meets the criteria mentioned above, to which is added the following feature: A sheath 137 containing a magnet 138 is superimposed on the sheath 139 containing a magnetic element or a magnet 140 with return 136 provided with a magnet 141, this which increases the magnetic power and can act as an ornament, for example, by adding lace on said reinforcing sheath. This sheath can also support the brand logo.

Fig. It describes a cap 142, comprising an adjustment strap 143 which contains two magnets or magnetic elements 144, 145, a fixed 144 and a mobile 145. The strap passes through an eyelet 146 and folds back on itself to ensure adjustment.

Fig. lld shows a cap 147 with two adjustable straps 148 and 149 which each contain a mobile magnet or magnetic element. The adjustment is obtained by sliding the shoulder straps against each other.

The garter belt of Figure 12 shows meanwhile, a device according to an embodiment of the invention which prevents tearing the bottom.

It is easier to install and remove than the traditional system. In place of the bottom clip, two movable magnets or magnetic elements 151 are used in a sheath 152, which can each be separated by a seam 153.

The closure on the bottom is made by contact between the two magnets or elements.

The height adjustment system can be done with a fixed magnet or magnetic element 154 and a mobile 155, which slides in a sheath 156.

The magnet or mobile element allows an adaptation to the measurements of the person but above all, it responds and adapts to different types of stockings. The basque (not shown) can consist of five sleeves each comprising two magnets or magnetic elements, a fixed and a mobile separated by a seam. Each sheath passes through a rectangular eyelet the size of the sheath plus a few millimeters, then closes on itself.

Various modes of rectangular sleeves which can be used with the invention have been described below, in a nonlimiting manner, with reference to FIGS. 13.

FIG. 13a shows a heavy inverted quilted sheath formed by a jersey ribbon 160 and a nylon ribbon 161 which are quilted 166 and turned. A strip of rhodoid 167 is then introduced into this pocket, then the whole is joined by a peripheral puncture 168.

Figure 13b describes a quilted sheath returned lightened. Here we use a nylon 169 strip, the sides of which are glued in order to obtain a hem which will reinforce the sides of the sheath. This hem can be replaced by an ultrasonic cut. The strip is then folded back on itself (arrow 170) lengthwise with an overflow from one end for a few millimeters.

A puncture 171 is then made on the two long sides 172 and on the bottom of the pocket 173 thus obtained.

Two strips of rhodoid 174 2mm wide and glued are placed along the long sides of the sheath. The sheath is then turned over (arrow 175) then stitched in 176 to trap the two strips of rhodoid and guide the translation of the magnet (not shown) in the sheath thus obtained 177.

Figures 13c and 13d show a silicone sheath 178, or treated to increase adhesion.

The contact surface of the sheath with the adjacent sheath can be covered with silicone 179, gum or semi-adhesive material, so as to increase the adhesion between the sheaths in contact. This slows the translation of the sleeves and increases the lifting force by creating a suction effect. The interior 180 of the sheath is covered with nylon 181 to facilitate translation of the magnetic element 182. The visible exterior 183 of the sheath is made of covered jersey. The assembly can be done by pricking or welding (hot or ultrasonic) (arrow 184).

The nylon and the jersey are assembled using an iron-on film 185 to obtain a first part of the sheath. The second part is made up of nylon inner face which is covered with the layer 179 of silicone. Depending on the behavior of the silicone with ultrasound, it will be applied before or after welding.

This sheath can have a specific shape, so as not to hinder the mobility of the magnet in the sheath. The edges of this sheath can be reinforced with a heat seal on the sides.

FIG. 14a shows a sectional view of a magnetic element 186 for a device according to an embodiment of the invention, composed of one or more rows of magnets 189 (here two rows are shown) fixed on a support 187 by by means of an adhesive 188 of a known type. The support 187, for example made of 0.2 mm thick polyester film, has different characteristics:

Good resistance to humidity (washing) and to chemical attack (detergents, perspiration, basic and acidic environments, - flexibility to support the movements of the user, sufficient stiffness to allow the device to return to its initial shape after deformation, good adhesion to the adhesive 188, - reduced thickness

Glue 188 has different characteristics: resistant to wet conditions (washing) and chemically aggressive (detergents, perspiration, basic and acidic media), good adhesion to magnets 189 and to support 187, flexible and impact resistant, easy to be molded, which allows the magnets to be embedded well, resistant to high temperatures (> 200 ° c). For example, a silicone-based adhesive resistant to 250 ° C can be used.

FIG. 14b shows a sectional view of the plastic mold 190 making it possible to produce the magnetic element 186 in strips of different lengths.

The body of the mold 190 has two grooves or troughs 192 and 194. The trough 192 has the shape of the magnetic element 186 to be obtained.

The chute 194 allows, for its part, the insertion of a flat element 193, made of ferromagnetic material, of elongated parallelepiped shape, the utility of which will be developed below.

An intermediate element 191 is placed in the mold on the internal face of the chute 192. It plays a non-stick role, preventing the glue from adhering to the mold 190.

The element 191 is for example formed from a plastic film, for example from polyethylene. Other mold embodiments are possible. For example, aluminum with a coating of material known under the brand name "Teflon®", or a mold entirely of polyethylene. In this case, the presence of film 191 can be avoided.

We will now describe the manufacture of the magnetic element 186, according to one embodiment of the invention.

After having placed the non-stick element 191 in the trough 192, the various rows of magnets 189 are placed, which are then naturally pressed against the bottom of the trough 194 thanks to the magnetic attraction exerted by the element 193 placed at the bottom of the chute 194. This arrangement makes it possible to avoid the displacement of the magnets 189 as well as the insertion of the glue under the magnets 189 during the injection of said glue 188.

After having covered the rows of magnets 189 with the adhesive 188, the support strip 187 is placed on the upper force of the layer of adhesive thus formed. We then come to make the upper rounding 195 and let it dry.

Drying can be done naturally (in the open air) on the understanding that a slightly humid environment facilitates the polymerization of this adhesive, or in a forced way (oven, heating resistors, ventilation or any other system). The operation of "Molding" of the magnet blocks with the adhesive can be done under vacuum, in a free atmosphere or under any other advantageous pressure / temperature conditions. Figure 14c shows a perspective view of the magnetic element 186 in its mold 190. The glue 188 and the support 187 are hidden in a half view

FIG. 15a shows a magnetic element 196 made up of alternating negative and positive magnets 198 and 199, the negative and positive magnets having different thicknesses. The magnets 198 and 199 are bonded to a support 201 with an adhesive 200 of a known type.

FIG. 15b shows two complementary magnetic elements 196 and 197, constituted as described above with negative magnets 198, 198 ', and positive magnets 199, 199'. The shape complementarity between the magnets 198 and the magnets 199 allows them to fit together when the magnets 198 are placed opposite the magnets 199 ', and the magnets 199 opposite the magnets 198'.

FIG. 15c shows an enlarged view of the two magnetic elements 196 and 197, which are inserted respectively in sheaths 202 and 202 'and which can be mobile or be fixed inside them.

The sleeves 202 and 202 ′ are made of fine fabrics,

(for example of the order of 75 to 80 microns thick) flexible, light and resistant in order to allow maximum approximation of the surfaces of the elements 196 and 197.

Although a priori more complicated, this arrangement of magnets 198, 199, 198 'and 199' has the following advantages: Allow transverse physical attachment of the elements 196 and 197, relative to each other, thanks to the lateral faces 203 of the magnets 199 and 203 'of the magnets 199', forming a transverse stop.

Increase the magnetic power of the assembly by increasing the contact surfaces between the magnets 199 and 199 ′, the surfaces of the lateral faces being added to the horizontal surfaces. - Increase the pinching of the fabric of the sheaths 202 and 202 'by forcing the fabric to follow the shape of the magnetic elements 196 and 197. This pinching makes it possible to better brake the sheaths once the garment has been adjusted and closed. Figures 15d to 15g show examples of different arrangements, for magnets 198 and 199, on one or more rows.

Magnets 186 and 187 are used here in the form of rectangular or square parallelepideds placed end to end by alternating negative magnets and positive magnets of different thickness.

More specifically, FIG. 15d shows a magnetic element 196, seen from above, where the magnets 198 and

199 are alternated in a single row. The polarities of the magnets are also alternated in order to increase the magnetic power of the block.

FIG. 15e shows a magnetic element 196, seen from above, with magnets 198 and 199 alternated in two rows symmetrically. The polarities of the magnets are always alternated but according to two dimensions and whatever the type of magnet. Surprisingly, this alternation of polarities allows a factor ten gain in magnetic power.

FIG. 15f shows a magnetic element 196, seen from above, in which the magnets 198 and 199 are alternated in two rows and in two dimensions thus forming a "checkerboard".

FIG. 15g shows a magnetic element 196, seen from above, where the magnets 198 and 199 are alternated in three rows and in two dimensions thus forming a "checkerboard" of greater lateral dimension.

The number of rows and magnets per row is not exhaustive and depends on the desired power for a given application. The magnets can be arranged either symmetrically or in a "checkerboard" pattern, whatever the number of rows.

FIG. 15h shows a parameterized view of the magnetic element 196. The surfaces in contact depend on the difference in thickness of the two magnets 198 and 199, denoted x for given dimensions of the magnetic closure.

As an indication, for a magnetic element with two rows of four magnets each, with

and ξ = 6mm, we get:

- for symmetrical alternation, a contact surface of 180 mm ² ,

- for a checkerboard alternation, a contact surface of 192 mm ²

- for a magnetic element with magnets of the same thickness, ie ε = δ = lmm and α = 0mm, a contact surface of 144 mm ² For the same volume of magnets, compared to the conventional configuration (same thickness), the symmetrical alternation makes it possible to increase the contact surfaces by a factor of 1.25, and by 1.33 for the checkerboard alternation.

FIG. 16a shows a magnetic element 204 constituted by an alternation of negative 206 and positive 207 parallelipiped magnets, which have different thicknesses, of the double alternation type, that is to say that the row or rows consist of a succession of two magnets 206 then two magnets 207 then two magnets 206. The magnets 206 and 207 are bonded to a support 209 of the type described above, with an adhesive 210 of a known type. FIG. 16b shows top views of the magnetic element 204 in one and in two rows. The polarities of the magnets are always alternated according to one or two dimensions, and some is the type of magnet. Each magnet has the opposite polarity to that of the magnets that surround it and with which it is in contact. Each magnetic element can have one or more rows composed of one or more magnets according to the desired magnetic power.

FIG. 16c shows an enlarged view of two complementary magnetic elements 204 and 204 ′, which are inserted respectively in sheaths 211 and 211 ′ and which can be mobile or be fixed inside them. The sleeves 202 and 202 ′ must be fine, flexible, light and resistant in order to allow maximum approximation of the surfaces of 204 and 204 ′. This arrangement of magnets 206, 207, 206 'and 207' has the same advantages as for the single alternation block of Figures 15, namely: Excellent physical grip, - increased contact surfaces and therefore magnetic grip, better pinching of the sheaths.

FIG. 16d shows a magnetic element 205 composed of a triple alternation of magnets 206 and 207, of different thicknesses, fixed as above.

To optimize the magnetic power required for each application, we can therefore vary various parameters: the type of alternation of the magnets (single, double, triple, ...) the number of rows, the number of magnets per row, l thickness of magnets. We see here the very wide range of solutions that the invention can present, in particular in some of its embodiments.

Figures 17a and 17b show another embodiment of complementary magnetic elements

212 and 213, which can be used with the invention, which are effective since they generate a looping effect of the magnetic field by positioning a row of magnets

214 between two rows of ferromagnetic elements

215 and 216 in soft material.

The magnetic element 212 is composed of one or more rows of magnets 214 which are glued, welded or otherwise fixed, by means of an element 218 '' (double-sided adhesive, for example, of known type, to ferromagnetic elements 215 of soft material. The assembly is fixed on a support, for example flexible plastic, 217 with an adhesive 218 of known type, as previously described. .

The block thus formed can be inserted into a fabric sheath 219 or the like, in which the block can move (long sheath) or be more or less fixed (short sheath). As for the magnetic element 213, it is composed of one or more ferromagnetic elements 216 fixed on a support 217 ′ (for example of mild steel of the XC10 type supplemented by protection of the steel strips against oxidation / corrosion due to washing. household appliances), with glue 218 ', of known types. This new block can also be inserted into a fabric sheath 220 or the like, and slide (long sheath) or be fixed (short sheath) inside of it. FIG. 17b corresponds to a sectional view of the magnetic elements 212 and 213.

FIG. 17c shows a strip of magnetic element 212 in perspective. Certain parts of components have been hidden to allow the visualization of each component, as well as a possible arrangement of these components.

As an indication, the magnets 214 are 6x3x1 mm parallelepipeds arranged in two rows, the elements 215 are 12x3x1 mm parallelepipeds made of mild steel treated with anti-corrosion of the same type as that described with reference to the support. The support, meanwhile, is formed by a plastic band 12 mm wide and 0.2 mm thick. The element strip 212 has a width of 14 mm and a thickness of 3 mm. All these values correspond to a given application for a given use. FIGS. 18a and 18b correspond to the application of the embodiment of the magnetic elements of FIGS. 17 according to the arrangements of the magnets of FIGS. 15 and 16.

Figure 18a shows two complementary magnetic elements 221 and 222.

The magnetic element 221 is composed of a simple alternation of magnets 225 and 226, of different thicknesses, fixed by an element 231 '' (glue) to ferromagnetic elements 215 of the same thickness. The assembly is fixed to a support 230 with an adhesive 231 of known type. The block thus formed can slide or remain fixed in a sheath 232 made of fabric or the like.

The magnetic element 222 is composed of a simple alternation of ferromagnetic elements 228 and 229 of different thicknesses, fixed on a support 230 'with an adhesive 231' of known type. The block thus formed is complementary to the magnetic element 221 and can slide or remain fixed in a sheath 233 of fabric or the like.

Figure 18b shows two magnetic elements 223 and 224 of complementary shapes.

The magnetic element 223 is composed of a double alternation of magnets 225 and 226, of different thicknesses, fixed to ferromagnetic elements 227 made of soft material of constant thickness. The magnetic element 224 is composed of a double alternation of ferromagnetic elements 228 and 229 of different thicknesses.

The magnetic elements 221, 222, 223 and 224 can be in one or more rows. As an indication, magnets 225 1.5 mm thick, magnets 226 0.5 mm thick, complementary ferromagnetic elements 228 and 229 of respective thicknesses 0.5 mm and 1.5 mm, and elements 227 of thickness 1 can be used. mm.

FIGS. 18c and 18d correspond to two possible applications of the embodiment of the magnetic elements of FIGS. 17.

FIG. 18c shows two complementary magnetic elements 234 and 235 making it possible to form a ferromagnetic "U" around a row of magnets.

The magnetic element 234 is composed of one or more rows, of one or more magnets 236, which are fixed with one or more rows of ferromagnetic elements 237 made of soft material, for example mild steel.

On one end of this block thus formed, one comes to glue, weld, or fix by another device 241, a ferromagnetic element in soft material 239 whose height is less than the thickness of the block in order to allow complementarity with the item 235.

The magnetic element 235 is composed of one or more rows, of one or more ferromagnetic elements of soft material 238, mild steel, where one comes to glue, weld, or fix by another device 242, on one ends, one or more ferromagnetic elements 240, the height is greater than the thickness of the block in order to allow a complementarity of form with the element 234.

FIG. 18d shows two complementary magnetic elements 243 and 244 making it possible to enclose a row of magnets in the middle of ferromagnetic elements.

The magnetic element 243 is composed of one or more rows, of one or more magnets 236, fixed 5 (s) with one or more rows of ferromagnetic elements 237. On the two ends of this block thus formed, there is glue, weld, or fix by any other means 241 and 241 ', ferromagnetic elements 239 and 239' whose height is less than the thickness of the block in order to allow complementarity with element 244.

The magnetic element 244 is composed of one or more rows of one or more ferromagnetic elements 238 where one comes to glue, weld, or fix by other means 242 and 242 ', on both ends, ferromagnetic elements 240 and 240 ', the height of which is greater than the thickness of the block in order to allow complementarity with the element 243. The two magnetic closure systems of FIGS. 18c and 18d have the advantages of increasing the surfaces surrounding the magnets and therefore to increase the magnetic power and the looping effect. In addition, the elements 240, 240 ′ make it possible to produce translational blockages by mechanical stops between the complementary magnetic elements 234 and 235, 243 and 244. As an indication, the elements 236, 237, 238 can be 1 mm thick and the elements 239, 239 ', 240, 240' can have a height of 1.6 mm. The ferromagnetic elements 237, 238, 239, 239 ', 240, 240' can be made of mild steel treated with anti-corrosion.

FIGS. 19a and 19b show the shape of the magnetic fields of the magnets of the embodiments of the magnetic elements of FIGS. 17 and 18.

FIG. 19a shows a conventional magnetic closure 245 composed of two rows of magnets 247 whose polarities are alternated, as previously described. The magnetic fields 248 result from the interaction of the two rows of magnets 247 and form a loop through the alternation of the polarities. Element 246 represents the separation formed by the sleeves in which the magnet blocks are inserted. FIG. 19b shows a magnetic closure 245 'composed of one or more rows of magnets 247, with alternating polarities, with, on either side, one or more rows of ferromagnetic elements 249 and 249'. The magnetic fields 248 'result from the interaction of the magnets 247 and the ferromagnetic elements 249 and 249', which charge positively and negatively in opposition to the polarities of the magnets 247. The element 246 'represents the separation constituted by the sheaths in which the magnet blocks are inserted.

This sandwich configuration allows the magnetic fields 248 'of the magnets 247 to be redirected inside the ferromagnetic elements 249 and 249 ', and create a loop of magnetic fields. The configuration of FIG. 19b has advantages over the configuration of FIG. 19a, in particular in that it makes it possible to: loop the magnetic fields and keep the same magnetic power with half the magnets, decrease the cost of closing, - reducing the interaction of magnetic fields with the outside.

FIG. 19c shows another embodiment of a device according to the invention showing two identical parts facing each other, each corresponding to the upper part of FIG. 196.

In this context, the following values can be adopted: indicative thickness of magnets 247, 247 ': 0.5mm or 0.8mm, indicative thickness of mild steel plates (248, 249, 248', 249 '): 0, 8 to 1.0mm. Or a total thickness of the system: T = 1.6 + 2 = 3.6mm instead of 4.5mm without doubling of parts and this with a similar magnetic power.

Figures 20a to 20d show another embodiment of magnetic elements, usable with one invention, which are effective because they can slide with or without sleeves. The magnetic elements are shown in section and the slide links are symbolized in perspective. FIG. 20a shows a magnetic element 263 produced as above (that is to say in this case, two rows of magnets 250 fixed on a support 251 with an adhesive 252 of known type), the two ends of which are pierced with holes cylindrical 254 and 254 '. The holes 254 and 254 ′, of circular type, allow the passage of wires or other elements of round section 253 and 253 ′ which ensure the translational guidance of the magnetic element 263. FIG. 20b shows another similar magnetic element 264 to 263, but with holes of square section 256 and 256 'allowing the passage of the guide elements in translation, for example formed of rigid or flexible rods of square section 255 and 255'.

FIG. 20c shows a magnetic element 265 composed of two rows of magnets 250 fixed on a support 251 with an adhesive 252 of known type and whose support 251 is covered with adhesive 252. This magnetic element 265 is drilled in four places, at namely two cylindrical holes 258 and 258 'on each end and two other holes 260 and 260' in the upper part. Each hole accommodates a wire or an element of round section 258, 258 ', 260 or 260' which ensures the translational guidance of the magnetic element 265.

FIG. 20d shows a magnetic element 266, similar to 265, but with only circular holes 262 and 262 ′ in the upper part of the strip formed by the element, allowing the passage of the guiding elements in translation of round section 261 and 261 '. This configuration frees the sides of the magnetic element 266. The different configurations of FIGS. 20a to 20d, given by way of example, make it possible to guide a magnetic element, whether inside a sheath or with an open sheath (see fig. 22a and 22b) or without a sheath . The magnetic elements shown are composed of two rows of magnets, but there can be one or more rows.

The quality of guidance depends on the type of guides used (shape of the section, size of the section, material used) and the number of holes drilled. In the configurations of FIGS. 20c and 20d, the guides can have square sections or of another shape.

As an indication, the use of metal guides (for example wire type) allows a more precise guidance of the magnetic element than the use of linen wire for example. On the other hand, linen thread makes it possible to better follow a complex contour like a body part. The choice is made according to the desired application.

Figures 21a and 21b show another embodiment of magnetic elements, usable with the invention, guided in translation without sheath.

FIG. 21a shows a magnetic element 276 composed of two rows of magnets 268 with, on both sides, parallelepipedic elements 269 and

269 'which are fixed to the magnets 268 by gluing, welding or other fixing system.

The block thus formed is fixed to a support 267 by gluing, welding or other fixing system 275.

The support 267 can be rigid or flexible depending on the desired applications. Elements 269 and 269 ' have holes 270 and 270 'which allow the linear guidance of the magnetic element 279 on wires or element of round section 271 and 271'. The section of the elements 271 and 271 ′ can be square or of another shape.

FIG. 21b shows a magnetic element 277, similar to the element 276, with guide supports 272 and 272 'open laterally outward, having slots 273 and 273'. These slots 273 and 273 'have rectangular sections and receive the guide elements 274 and 274' of square section.

FIGS. 22a and 22b show two magnetic elements 278 and 279 inserted respectively in open sleeves 285 and 286, which allows direct metal-to-metal contact, without any intermediate fabric forming an air gap.

Such an arrangement will make it possible to reduce the number of magnets and therefore the price, for equal magnetic power.

The magnetic element 278 is composed of one or more rows of magnets 280 fixed on a support 282 with an adhesive 281 of known type. The support 282 is embedded in the adhesive 281 and two or more holes 283 are made in the upper part of the magnetic element 278. These holes 283 allow the passage of the guide elements 284 which allow the translation of the magnetic element 278. The guide elements 284 are fixed to the open sheath 285 by gluing, welding, sewing or another system.

The magnetic element 278 is composed of one or more rows of magnets 280 fixed on a support 282 'with glue 281' of known type. The magnetic element 278 is fixed to the open sheath 286 by gluing, welding, sewing or another system.

FIG. 22b shows more precisely the two magnetic elements 278 and 279 in perspective. The sheath 285 is not shown in order to show the magnetic element 284 and a possible guide system 284. The magnetic element 284 can thus slide to adjust the closure. The element 279 remains fixed inside the open sheath 286.

The same type of open sheaths with mild steel plates added (idem fig. 19c) or to replace the magnets (fig. 19b) is possible here.

Figures 23a to 23b show another embodiment of magnetic elements 287 and 288, usable with the invention, which allow to close and adjust a garment or any other application.

FIG. 23a shows two magnetic elements 287 and 288 which are composed, as before, of one or more rows of magnets 289 fixed to a support 290 with an adhesive 291 of known type. The magnetic element 287 is inserted in a sheath 292 of the long type and is fixed inside.

The magnetic element 288 remains inserted in a sheath 293 of the short type and remains fixed inside. The closure is not adjusted by sliding one magnetic element relative to the other but by direct positioning of a short magnetic element 288 on a long magnetic element 287. The number of magnets 289 per row of the magnetic element 287 depends on the desired adjustment range. The number of magnets 289 per row of the magnetic element 288, as well as the number of rows depends on the magnetic power (clip) required. Figure 23a corresponds to a "wide" setting of the closure.

Figure 23b shows an intermediate position of the adjustment of the closure in the magnetic elements 287 and 288. Figure 23c corresponds to a "tight" adjustment of the closure.

This adjustment mode can also allow adjustment of the magnetic power of the closure by positioning more or less magnets of the magnetic element 288 opposite the magnets of the magnetic element 287. The more the number of magnets in contact is important, the greater the magnetic power of the closure. In this case, the adjustment is made by the sliding of one of the magnetic elements inside its sheath.

This type of sheath can thus be opened (idem fig. 22a) in order to reduce the number of magnets (= cost) and lighten the system.

FIG. 24 shows a shoe 300 with tongue 301 provided with a device 302 also shown diagrammatically at 302 ′) according to an embodiment of the invention.

The laces are here replaced by the sheath 303 containing two blocks of articulated magnets 304 and 305.

One 304 is movable and slides on an electrical circuit 306 (306 ') placed in the sheath 303. This circuit includes, for example, bonded contactors on a flexible PVC film, which makes it possible to obtain a circuit of easily adaptable shape due to its great flexibility.

The other magnet 305 is fixed in said sheath.

Six LEDs 308, 308 ', whose light element 309 pierces the top of the sheath, indicate the level of tightening.

They are supplied by the circuit 306 mentioned above.

More specifically, it comprises two conductive strips 310 and 311 located opposite and electrically insulated from each other by a support 312 (flexible plastic sheet, for example rodoid). Each blade is connected to the opposite bar of a stack 313 located in the sole 314 of the shoe 300.

The sheath 301, folds over a loop 319 of plastic connected to the shoe, for example by two elastic points (not shown), to make the movable magnet 304 cooperate with the fixed magnet 305 opposite.

By moving during tightening, the magnet 304 closes then opens different branches 315 ', 316', 317 ', ... of the circuit 306' which turns on the LEDs 308 '. Finally, a switch 318 (318 ') of the circuit is provided and can be actuated manually by the user.

FIG. 25 shows another embodiment of a shoe 320 according to the invention in which the laces have here again been replaced by a sheath 321 containing two magnet blocks, one fixed 322 and the other mobile 323 who will move along an electrical circuit integrated into the sheath.

This circuit is powered by a button cell 324 connected to eight LEDs 325 (325 'in the duplicate diagram). integrated this time not in the tongue itself but on the logo of the shoe and comprises, as in the case of FIG. 24, two blades 310 and 311 connected to the poles of the battery, the magnet 323 creating the closing of the circuit in front of a specific led during its movement.

The LEDs thus light up according to the tightening.

The sheath passes through a rod loop, for example in translucent orange PVC, mobile in rotation, adjusted to the shoe.

In this embodiment, the circuit 326 (326 ') can be closed not by a switch, but for example by folding and pinching the ends of the blades 310 and 311 together.

FIG. 26 shows another embodiment of the tongue 330 for a shoe 331, the sheath passing here in a loop 332 before folding back on itself. This loop is then connected to the shoe by an elastic band 333, which, once the magnet is positioned, exerts the clamping force in return. The magnet 332 is fixed in the shoe, the magnet 333 moving when one pulls. on the buckle when tightening. This magnet slides on the electrical circuit and turns on the diodes. It is therefore an alternative embodiment of FIG. 25. Figures 27 are perspective views of a watch 340 having two sets of magnets 341, 342, each set comprising a fixed magnet (341 ', 342') and another sliding mobile (341 '', 342 '') along two rails 343 made of plastic threads.

The bracelet is closed by matching the fixed magnet of one branch with the mobile magnet of the other branch, the adjustment then being possible thanks to the translation of the mobile magnets (cf. FIG. 27b and 27c).

Figures 28a and 28b show another embodiment of tongue 349 and shoe 350 in which the laces are replaced by a sheath 351 passing through three loops 352, 353, 354 arranged in place of the holes for the laces.

The sheath contains four mobile magnets, namely three 355 round magnets and a block of magnets.

356, for example signed for some for a rodoid support blade 357, the sheath 358 of the sheath being for example a white nylon.

The end of the sheath is fixed from the side by means of the magnet block 356 which cooperates with a fixed magnet block in the shoe. The other three magnets interact with similar magnets attached to the shoe. The sheath is thus held in position.

To tighten, pull on the tongue then fold the end of the sheath against the shoe to maintain the settings.

Figures 29a to 29c show another embodiment of a shoe 360 according to the invention in which the latter comprises two sleeves 361, 362 symmetrical opposite, each forming a transverse loop with a longitudinal return 366 around which the loop passes, mobile magnets 363 in the sleeves being placed towards the end of the tongues and coming to cooperate with a fixed magnet 364 located on the tongue portion 365 secured to the shoe.

In certain embodiments, it is also possible to provide two parallel sets of transverse tongues.

Figures 30a to 30c show an embodiment of bag 370, using a magnet device 371 according to an embodiment of the invention. The device 371 will allow a horizontal closure (see FIGS. 30b and 30c) of the bag, the opening of which is adjustable by the movement (arrows 372) of the magnets (373) contained in the sheath 374 fixed at the top on the edge of the bag.

FIGS. 31a and 31c show another embodiment of the bag 380 with adjustable flap 381. The flap 381 can be adjusted in height as a function of the size of the contents of the bag by means of mobile magnets 382 arranged in vertical sleeves 383 along the lateral peripheral edges 384 of the bag flap, which cooperate with fixed magnets 365 fixed on the front face of said bag.

Figures 32a and 32b show a skirt 390 provided with magnets 391, 392; 393, 394, inserted in respective sheaths 395, 396, compartmentalized, allowing the skirt to be fixed at the waist, two of the magnets 391, 394 being of complementary shape, part of which is thicker than the other, so as to come and hang one on the other.

In the belt, one of the elements is fixed on one side and movable on the other side of the belt. Figures 33a and 33b show a closed and open garment, provided at the location of each of its buttons, on one side (which is for example the side of the opening) of magnets 401 fixed alternately of sign + - + and on the other side of magnets 403, 404, movable in sheaths 405, of opposite signs and able to cooperate with the fixed magnets.

As is obvious and as it follows from the above, the present invention is not limited to the embodiments more particularly described. On the contrary, it embraces all variants and in particular:

- The “anti-pull-out” bra. It contains an alarm which is triggered if the bra is torn off. This system can thus allow an attacker to flee.

- The handbag with alarm. This bag is equipped with a handle which, when the bag is torn off, remains in the user's hand. This handle is connected by magnetic contact to the rest of the bag; a wire from a battery to a magnet which can be located at the top of the bag. This magnet is contact with a second magnet on the handle. This handle contains a wire which goes from the magnet mentioned above, to a third magnet. This third magnet is fixed by magnetic contact to a fourth magnet which can be located at the top of the bag. This fourth magnet is connected to a wire which goes to a relay. In the event of a breakout, the relay is no longer powered by a battery and triggers an alarm. The thief is therefore left with a bag that emits a siren or a voice message "Au thief! Thief ! ". - The bra "remote control and opening adjustable remotely" which facilitates the dressing and undressing of people with disabilities or reduced mobility.

The garter belt with alarm, if one of the four supports of the garter belt releases, an alarm is triggered.

- Magnetic closure of the strap that surrounds the umbrella in the closed position.

- The sweatband with magnetic closure instead of the Velcro® system, which after several uses, and under the effect of heat, loses its hanging properties.

The tie with pre-established knot. The knot consists of a magnet or magnetic element which will be attached to the magnet or mobile magnetic element located on the neck and thus adapt to the user's neck.

- Sports gloves with closure and adjustment by magnetic system according to the devices provided by the invention.

Protective equipment such as helmets, elbow pads, knee pads ... with closure and adjustment by magnetic system in place of traditional closure systems. The magnets can advantageously be covered one by one with a protective layer also by nickel / gold galvanization or nickel / nickel / gold which will prevent the magnets from rusting and which will make the magnets hypoallergenic.

As we have seen, the invention described can find numerous applications in various fields of use, in particular: corsetry: bras, garter belts, basques, corsets, panties, shoes and the like: sports shoes, city, ski, boots, roller skates, ice skates hats: caps, hats, hats, kepis clothing: jackets, shirts, blouses, overalls, pants, bermudas, skirt, dress, coat, removable hood ,. .. diapers, sanitary napkins medical equipment: removable / adjustable splints, dentist's bib clothing accessories: belts, suspenders, gloves, mittens, ties and bow ties ready made protective accessories: motorcycle helmets, bicycle helmets, site, riding bomb, knee pads, elbow pads, shin guards, breastplates fashion accessories: watches, bracelets equipment and diving suits luggage: suitcases, backpacks, shoulder bags, briefcases, document holders, sports bags, handbags ... office and school supplies: school bags, binders, folders, organizer, sorters, ... clothespins.
