The members (3, 4) fit into each other and one member (4) can be rotated to make or break a magnetic circuit and thereby open or close the garment. Said closure is particularly suitable for closing garments of all kinds but may be used wherever two parts of an article are to be joined.

Description

1 DISPOSITIF DE FERMETURE DE VETEMENT OU AUTRES. 1 DEVICE FOR CLOSING CLOTHING OR THE LIKE.
La présente invention concerne des boutons . magnétiques pour l'habillement, destinés à se substituer à i des boutons ordinaires, utilisés avec des boutonnières.The present invention relates to buttons. magnetic buttons for clothing, intended to replace i ordinary buttons, used with buttonholes.
--
5 L'utilisation des boutons ordinaires exige la création d'une découpe dans le tissu, appelée boutonnière, ce qui endommage la trame du tissu, impose la confection d'une bordure ourlée en fil pour protéger le tissu, ce qui nécessite une main d'oeuvre assez importante.5 The use of ordinary buttons requires the creation of a cutout in the fabric, called a buttonhole, which damages the weft of the fabric, requires the making of a hemmed edge of wire to protect the fabric, which requires a hand of rather important work.
10 De plus, le bouton doit être lui-même fixé par un fil d'une longueur ménageant l'épaisseur du tissu et rebobiné sur lui-même. Si ce fil se casse, l'usager doit recoudre le bouton et si à cette occasion, le bouton se perd, il lui faut utiliser un bouton identique à approvisionner.In addition, the button must itself be fixed by a length of wire sparing the thickness of the fabric and rewound on itself. If this thread breaks, the user must sew up the button and if on this occasion, the button is lost, he must use an identical button to supply.
15 La présente invention a pour objet de résoudre les inconvénients sus-évoqués en mettant en oeuvre un nouveau type de dispositif de fermeture qui ne nécessite pas pour sa mise en oeuvre la formation de boutonnières.The object of the present invention is to solve the above-mentioned drawbacks by implementing a new type of closure device which does not require the formation of buttonholes for its implementation.
A cet effet, le dispositif de fermeture pourTo this end, the closing device for
20 vêtements ou autres articles, destiné à se substituer aux boutons ou boutonnières classiques, composé de deux éléments fixés chacun à une des pièces du vêtement ou de 1'article à fermer et destinés à venir en contact 1 'un avec 1 ' autre par des surfaces de contact qu'ils comportent chacun et se20 articles of clothing or other articles, intended to replace conventional buttons or buttonholes, composed of two elements each attached to one of the pieces of the article of clothing or article to be closed and intended to come into contact with one another by means of contact surfaces they each have and are
25 maintenir en contact l'un avec l'autre pour assurer la fermeture du vêtement ou de 1 'article se caractérise essentiellement en ce que :25 keeping in contact with each other to ensure the closure of the garment or article is essentially characterized in that:
- la force de maintien des deux éléments l'un contre l'autre est une force magnétique s 'exerçant entre eux deux, - l'un des éléments comporte, noyé dans sa masse, au moins un aimant permanent dont 1 'un des deux pôles au moins vient affleurer la surface de contact,the holding force of the two elements against each other is a magnetic force exerting between them, one of the elements comprises, embedded in its mass, at least one permanent magnet of which at least one of the two poles is flush with the contact surface,
- 1'autre élément comporte une pièce en matière ferromagnétique affleurant sa surface de contact et destinée à venir au contact de 1 'un ou des deux pôles de 1 'aimant de l'autre élément, de façon à fermer le circuit magnétique, ce qui assure le maintien étroit des deux éléments l'un contre- The other element comprises a piece of ferromagnetic material flush with its contact surface and intended to come into contact with one or both poles of the magnet of the other element, so as to close the magnetic circuit, which ensures the close support of the two elements one against
1 'autre. Lorsque l'usager désire fermer son vêtement, il lui suffit d'appliquer les deux éléments l'un contre l'autre pour que l'attraction magnétique assure un contact étroit. L'ouverture se fait par une traction sur les deux parties du vêtement qui doivent être séparées. De préférence, la surface de contact de l'un des deux éléments est ménagée en creux tandis que la surface de contact de l'autre est ménagée en saillie, de forme correspondante au creux, de façon que les deux éléments se situent parfaitement 1 'un dans 1 'autre au moment de leur rapprochement, le creux et la saillie réalisant un auto¬ centrage. Ainsi, le positionnement des deux parties du vêtement ou de l'article à assembler se fait d'une manière parfaite sans que l'usager ait à rechercher la position exacte des deux éléments l'un par rapport à l'autre. Avantageusement, le second élément, c'est-à-dire, celui extérieur au vêtement ou à 1 ' article est composé de deux parties dont une est interne au vêtement et comporte la surface de contact et l'autre est externe au vêtement, les deux parties étant liées l'une à l'autre à travers le tissu. La partie extérieure forme organe de préhension et peut se présenter sous la forme d'un bouton destiné à être saisi pour, par exemple, exercer une traction sur le second élément en vue de sa séparation du premier. Une caractéristique applicable aux dispositions décrites plus haut, consiste à rendre mobile par rotation l'élément extérieur du dispositif de manière à permettre de faire coïncider ou de mettre hors contact les pôles de l'aimant et la plaque métallique par une simple rotation. Ceci évite la traction entre les deux parties de tissu à séparer lors de l'ouverture puisque la rotation suivant une fraction de tour permet de séparer angulairement plaque métallique et pôle(s) de l'aimant alors qu'en état de fermeture, la plaque placée sur celui-ci ou ceux-ci ferme le circuit magnétique et assure ainsi le maintien.The other. When the user wishes to close his garment, he only has to apply the two elements against each other so that the magnetic attraction ensures close contact. The opening is made by a pull on the two parts of the garment which must be separated. Preferably, the contact surface of one of the two elements is recessed while the contact surface of the other is protruding, of shape corresponding to the recess, so that the two elements are perfectly located 1 ' one in the other when they are brought together, the recess and the projection achieving self-centering. Thus, the positioning of the two parts of the garment or of the article to be assembled is done in a perfect manner without the user having to search for the exact position of the two elements with respect to each other. Advantageously, the second element, that is to say, that external to the garment or to the article is composed of two parts, one of which is internal to the garment and has the contact surface and the other is external to the garment, the two parts being linked to each other through the fabric. The external part forms a gripping member and can be in the form of a button intended to be grasped for, for example, exerting traction on the second element with a view to its separation from the first. A characteristic applicable to the arrangements described above consists in making the external element of the device mobile by rotation so as to make the poles of the magnet and the metal plate coincide or put out of contact by a simple rotation. This avoids the traction between the two parts of fabric to be separated during the opening since the rotation according to a fraction of a turn allows to angularly separate the metal plate and pole (s) of the magnet while in the closed state, the plate placed on it or these closes the magnetic circuit and thus ensures the maintenance.
Enfin, selon une autre caractéristique de l'invention, la plaque métallique est également un aimant, ce qui permet de renforcer l'effet d'attraction entre les deux éléments et d'accroître la force de fermeture. D'autres avantages, buts et caractéristiques techniques de l'invention apparaîtront à la lecture d'une forme préférée de réalisation donnée à titre d'exemple non limitatif en se référant aux dessins annexés en lesquels :Finally, according to another characteristic of the invention, the metal plate is also a magnet, which makes it possible to reinforce the effect of attraction between the two elements and to increase the closing force. Other advantages, aims and technical characteristics of the invention will appear on reading a preferred embodiment given by way of nonlimiting example with reference to the appended drawings in which:

Tel que représenté, le dispositif selon l'invention coopère avec deux pièces 1 et 2 du vêtement, ces pièces sont celles qui doivent être rabattues et maintenues rabattues l'une sur l'autre pour assurer la fermeture de ce dernier.As shown, the device according to the invention cooperates with two pieces 1 and 2 of the garment, these pieces are those which must be folded down and kept folded over one another to ensure the closure of the latter.
Le dispositif de fermeture comprend un premier élément 3 fixé à la pièce 1 et tourné vers l'extérieur du vêtement et un deuxième élément 4 fixé à la pièce 2 et tourné vers l'intérieur, ces deux éléments coopérant l'un avec l'autre pour assurer la fermeture du vêtement.The closing device comprises a first element 3 fixed to the part 1 and turned towards the outside of the garment and a second element 4 fixed to the part 2 and turned inward, these two elements cooperating with each other to ensure the closure of the garment.
Chaque élément 3 et 4 présente un axe de symétrie, cet axe de symétrie étant perpendiculaire à la pièce correspondante 1 ou 2. Chaque élément est par ailleurs, doté d'une surface de contact, par laquelle il vient en contact avec celle de l'autre, cette surface de contact étant une surface de révolution ayant comme axe de symétrie, l'axe de symétrie de l'élément sur lequel elle est formée.Each element 3 and 4 has an axis of symmetry, this axis of symmetry being perpendicular to the corresponding part 1 or 2. Each element is moreover, provided with a contact surface, by which it comes into contact with that of the other, this contact surface being a surface of revolution having as axis of symmetry, the axis of symmetry of the element on which it is formed.
La surface de contact de 1 'élément 3 est tournée vers l'extérieur tandis que la surface de contact de l'élément 4 est tournée vers l'intérieur.The contact surface of the element 3 faces outward while the contact surface of the element 4 faces inward.
Le premier élément 3, épousant par exemple une forme générale cylindrique est fixé à la pièce interne 1, par agrafes, coutures, sertissage, queues de fixation ou autres moyens.The first element 3, following for example a generally cylindrical shape is fixed to the internal part 1, by staples, seams, crimping, fixing tails or other means.
Cet élément est constitué par une matière synthétique inerte constituant masse 'enrobage d'un aimant 6 présentant une configuration générale en U, les deux pôles de l'aimant étant formés en extrémités des branches du U. Les surfaces polaires, comme on peut le remarquer sur les figures jointes, affleurent la surface de contact de l'élément 3 et sont disposées de manière diamétralement opposées par rapport à 1 ' axe de symétrie et en ecartement l'une de l'autre.This element consists of an inert synthetic material constituting the mass coating of a magnet 6 having a general U-shaped configuration, the two poles of the magnet being formed at the ends of the branches of the U. The polar surfaces, as can be noted in the accompanying figures, are flush with the contact surface of the element 3 and are arranged diametrically opposite with respect to the axis of symmetry and in separation from one another.
Pour des raisons qui seront exposées plus loin les surfaces polaires n'occupent au plus que la moitié de la surface de contact dont elles constituent une partie. En figure 2, on peut remarquer que le contour des surfaces polaires, projeté orthogonalement sur un plan normal à 1 'axe de symétrie de 1 'élément 3 épouse celui d'un quadrilatère tandis qu'en figure 6, on remarque qu'il épouse celui d'un secteur de cercle. Il est bien évident que d'autres formes de contour pourront être adoptées.For reasons which will be explained below, the polar surfaces occupy at most only half of the contact surface of which they form a part. In Figure 2, we can notice that the contour of the polar surfaces, projected orthogonally on a plane normal to the axis of symmetry of the element 3 follows that of a quadrilateral while in Figure 6, we notice that it follows that of a circle sector. It is obvious that other contour shapes could be adopted.
L'élément externe 4 est solidaire de la pièce externe 2 et épouse une forme générale cylindrique. Cet élément 4 est constitué en une matière synthétique inerte constituant support d'une pièce métallique magnétisable 7. Cette pièce 7 est préférentiellement noyée dans la masse de l'élément 4 et affleure la surface de contact formée dans l'élément 4. Cette pièce métallique est destinée à venir au contact des deux pôles de 1 ' aimant 6 afin d'assurer la fermeture du circuit magnétique.The external element 4 is integral with the external part 2 and follows a generally cylindrical shape. This element 4 is made of an inert synthetic material constituting the support of a magnetizable metal part 7. This part 7 is preferably embedded in the mass of the element 4 and is flush with the contact surface formed in the element 4. This metal part is intended to come into contact with the two poles of the magnet 6 in order to ensure the closing of the magnetic circuit.
Cette pièce 7 est disposée de manière symétrique de part et d'autre de l'axe de symétrie de l'élément 4 et son contour, projeté sur un plan normal au dit axe de symétrie est celui d'un rectangle dont la longueur est égale ou supérieure à la valeur de 1 'entraxe entre les deux surfaces polaires et dont la largeur est inférieure à 1 'ecartement entre les deux surfaces polaires.This piece 7 is arranged symmetrically on either side of the axis of symmetry of the element 4 and its outline, projected on a plane normal to said axis of symmetry is that of a rectangle whose length is equal or greater than the value of the center distance between the two pole surfaces and the width of which is less than the spacing between the two pole surfaces.
L'attraction magnétique s 'établissant entre l'aimant et la pièce métallique assure une bonne liaison des deux éléments 3, 4 l'un à l'autre. Cette liaison sera d'autant plus forte que l'attraction magnétique sera puissante et afin d'accroître cette liaison, la pièce métallique 7 pourra être constituée par un aimant venant affleurer par ses deux surfaces polaires, la surface de contact de l'élément 4. Les surfaces polaires de la pièce 7 se développent de manière diamétralement opposée par rapport à 1 ' axe de symétrie de l'élément 4 à ecartement l'une de l'autre et leur entraxe est égal à l'entraxe entre les surfaces polaires de l'aimant 6 de l'élément 3 de façon que les surfaces polaires de l'un des aimants 6 ou 7 puissent venir en regard et au contact des surfaces polaires de signe opposé de 1 'autre aimant 6 ou 7. En figure 7 est représenté un élément 4 dont la pièce métallique 7 est un aimant.The magnetic attraction being established between the magnet and the metal part ensures a good connection of the two elements 3, 4 to each other. This connection will be all the stronger as the magnetic attraction will be powerful and in order to increase this connection, the metal part 7 may be constituted by a magnet coming to be flush with its two polar surfaces, the contact surface of the element 4 . The pole surfaces of the part 7 develop diametrically opposite with respect to the axis of symmetry of the element 4 at a distance from each other and their center distance is equal to the center distance between the pole surfaces of the magnet 6 of the element 3 so that the pole surfaces of one of the magnets 6 or 7 can come opposite and in contact with the pole surfaces of opposite sign of the other magnet 6 or 7. In FIG. 7 is shown a element 4, the metal part 7 of which is a magnet.
Sur cette figure, on peut remarquer que le contour de chaque surface polaire projeté orthogonalement sur un plan normal à l'axe de symétrie épouse celui d'un secteur de cercle. Il est bien évident que toute autre forme de contour pourra être adoptée par exemple une forme quadrangulaire 4. Un élément 4 avec surfaces polaires telles que montrées en figure 7 sera plus particulièrement destiné à coopérer avec un élément 3 dont le contour de chaque surface polaire sera celui d'un secteur de cercle comme montré en figure 6 et défini plus avant. En revanche, un élément 4 présentant des surfaces polaires quadangulaires pourra être associé à un élément 3 comportant des surfaces polaires quadrangulaires comme montré en figure 2. Quel que soit le type de contour adopté, les surfaces polaires de l'élément 4 selon les formes de réalisation précédemment décrites n'occuperont au plus que la moitié de la surface de contact pour des raisons qui seront exposées plus loin.In this figure, we can notice that the contour of each polar surface projected orthogonally on a plane normal to the axis of symmetry follows that of a sector of a circle. It is quite obvious that any other shape of contour could be adopted for example a quadrangular shape 4. An element 4 with polar surfaces as shown in figure 7 will be more particularly intended to cooperate with an element 3 whose contour of each polar surface will be that of a circle sector as shown in Figure 6 and defined further. On the other hand, an element 4 having quadangular polar surfaces could be associated with an element 3 comprising quadrangular polar surfaces as shown in FIG. 2. Whatever the type of contour adopted, the polar surfaces of element 4 according to the shapes of embodiment previously described will occupy at most only half of the contact surface for reasons which will be explained below.
Les éléments 3 et 4 précédemment décrits et objets des figures 2, 6 et 7 sont équipés d'aimants venant chacun par leurs deux surfaces polaires nord et sud affleurer la surface de contact mais selon une autre forme de réalisation, comme on peut le voir en figures 8 et 9, l'aimant n'affleure la surface de contact de son élément 3 ou 4 respectif que par une seule de ses surfaces polaires, cette surface polaire se développant de manière symétrique de part et d'autre de 1 'axe de symétrie de 1 'élément et n'occupant au plus que la moitié de la surface de contact. Selon la configuration précédemment définie, les surfaces polaires de l'élément 3 et de l'élément 4 seront de signe contraire.Elements 3 and 4 previously described and objects Figures 2, 6 and 7 are equipped with magnets each coming by their two north and south pole surfaces flush with the contact surface but according to another embodiment, as can be seen in Figures 8 and 9, the magnet n is flush with the contact surface of its respective element 3 or 4 only by one of its polar surfaces, this polar surface developing symmetrically on either side of the axis of symmetry of the element and occupying not more than half of the contact area. According to the previously defined configuration, the pole surfaces of element 3 and element 4 will be of opposite sign.
De façon à permettre un auto-centrage des éléments 3 et 4 lors de leur attraction mutuelle, la surface de contact de l'un d'entre-eux forme un creux conique tandis que la surface de contact de l'autre forme une saillie conique correspondant au creux.In order to allow self-centering of the elements 3 and 4 during their mutual attraction, the contact surface of one of them forms a conical hollow while the contact surface of the other forms a conical projection corresponding to the hollow.
A titre d'exemple purement indicatif, le creux est ménagé dans l'élément 3 tandis que la saillie est pratiquée sur l'élément 4.As a purely indicative example, the hollow is formed in the element 3 while the projection is made on the element 4.
Selon la forme préférée de réalisation, l'élément 4 est constitué de deux parties 4A, 4B dont une, la partie 4A est interne au vêtement et comporte la surface de contact et l'autre, la partie 4B est externe au vêtement et constitue un organe de préhension qui rappelle de préférence l'aspect d'un bouton vestimentaire.According to the preferred embodiment, the element 4 consists of two parts 4A, 4B, one of which, the part 4A is internal to the garment and has the contact surface and the other, the part 4B is external to the garment and constitutes a gripping member which preferably recalls the appearance of a clothing button.
Ces deux parties 4A, 4B sont liées l'une à l'autre tant en translation qu'en rotation par une broche 8 fixée de manière rigide à l'une et à l'autre et engagée au travers d'un oeillet 9 ménagé dans la pièce 2 du vêtement.These two parts 4A, 4B are linked to each other both in translation and in rotation by a pin 8 rigidly fixed to one and to the other and engaged through a eyelet 9 formed in part 2 of the garment.
Avantageusement, l'élément 4 est monté sur la pièce 2 avec possibilité de rotation suivant son axe de symétrie. Cette disposition est particulièrement intéressante puisqu'elle permet par simple rotation suivant un quart de tour de la pièce 4 de rompre le contact entre la pièce 7 et la ou les surface(s) polaire(s) de l'élément 3, ce qui permet une séparation des deux éléments sans avoir à exercer un effort de traction sur l'élément 4. II y a lieu de noter que pour des éléments 3 et 4 présentant chacun deux surfaces polaires, une rotation suivant un demi-tour de l'élément mobile 4 amène les surfaces polaires de même polarité en regard l'une de l'autre ce qui induit un effet de répulsion qui assure assitôt l'ouverture du vêtement.Advantageously, the element 4 is mounted on the part 2 with the possibility of rotation along its axis of symmetry. This arrangement is particularly advantageous since it allows by simple rotation according to a quarter turn of the part 4 to break the contact between the part 7 and the pole surface (s) of the element 3, which allows separation of the two elements without having to exert a tensile force on the element 4. It should be noted that for elements 3 and 4 each having two polar surfaces, a rotation of the mobile element in a half-turn 4 brings the polar surfaces of the same polarity opposite one another which induces a repulsion effect which assures the opening of the garment.
La partie 4B de l'élément 4 est constituée, selon une autre forme de réalisation par un aimant comme représenté en figure 10 afin de renforcer la force de maintien des éléments 3 et 4 l'un contre l'autre. Cet aimant sera recouvert de toute matière appropriée.The part 4B of the element 4 is constituted, according to another embodiment, by a magnet as shown in FIG. 10 in order to reinforce the holding force of the elements 3 and 4 one against the other. This magnet will be covered with any suitable material.
La force de liaison des deux éléments l'un à 1 'autre peut être accrue dans des proportions importantes si est associée à la liaison par aimants, une liaison par obstacle. Cette liaison par obstacle comme on peut le voir en figures 11 à 14 est par exemple constituée par au moins deux organes de raccord dont un est solidaire de l'élément 3 et l'autre de l'élément 4, destinés par rotation relative des deux éléments à coopérer en engagement de forme l'un avec 1 ' autre pour assurer un blocage axial des deux éléments l'un par rapport à l'autre.The bonding force of the two elements to one another can be increased in significant proportions if associated with the bonding by magnets, a bonding by obstacle. This obstacle connection, as can be seen in FIGS. 11 to 14, is for example constituted by at least two connecting members, one of which is integral with element 3 and the other with element 4, intended by relative rotation of the two. elements to cooperate in form engagement with one another to ensure axial locking of the two elements relative to each other.
Selon la forme préférentielle de réalisation, un des deux organes de raccord est constitué par deux griffes 10 diamétralement opposées et l'autre est constitué par deux pattes 11 diamétralement opposées formant saillies radiales sur leur élément 3 ou 4. L'écart angulaire entre les griffes est plus important que la largeur des pattes et ces dernières, par rotation des deux éléments 3 et 4 s'engagent dans les griffes 10 • A titre d'exemple purement indicatif, les griffes 10 sont portées par l'élément 4 tandis que les pattes 11 sont portées par l'élément 3.According to the preferred embodiment, one of the two connecting members is constituted by two diametrically opposite claws 10 and the other is constituted by two diametrically opposite lugs 11 forming radial projections on their element 3 or 4. The angular distance between the claws is more important than the width of the legs and the latter, by rotation of the two elements 3 and 4 engage in the claws 10 • As a purely indicative example, the claws 10 are carried by the element 4 while the legs 11 are carried by element 3.
Le dispositif selon l'invention tel que précédemment décrit permet d 'assurer une fermeture avec une grande force de maintien et une ouverture sans risque d'arrachement. De plus le dispositif tel que précédemment défini peut être utilisé pour tout usage de fermeture provisoire tel que vêtement, sac, valise, serviette et autres articles de maroquinerie, sangle, attache de dossier, portes de tentes, ou serrurerie de portes. The device according to the invention as previously described makes it possible to ensure closure with a large holding force and an opening without risk of tearing. In addition, the device as defined above can be used for any use of temporary closure such as clothing, bag, suitcase, towel and other leather goods, strap, file attachment, tent doors, or door locks.
