Abstract
Description
La présente invention concerne un contact électrique à poussoir destiné à provoquer l'ouverture ou la fermeture d'un circuit sous l'effet d'une pression généralement exercée manuellement, ce poussoir étant particulièrement adapté aux montres et chronomètres utilisant comme source d'énergie l'électricité. The present invention relates to an electrical push button intended to cause the opening or closing of a circuit under the effect of a pressure generally exerted manually, this push button being particularly suitable for watches and chronometers using as energy source l 'electricity.
Les montres de ce type, quelque soit leur mode de lecture (cristaux liquides, diodes électroluminescentes ou aiguilles) ont en commun le fait de posséder un certain nombre de boutons-pous- soirs destinés à commander des fonctions particulières telles que la remise a l'heure, le changement de date, le pré-réglage d'une alarme ou simplement l'éclairage. Watches of this type, whatever their reading mode (liquid crystals, light-emitting diodes or hands) have in common the fact of having a certain number of push-buttons intended to control particular functions such as reset time, date change, pre-setting an alarm or simply lighting.
Les micro-mécanismes et les circuits electroniques qui constituent les parties actives de telles montres font l'objet d'une miniaturisation de plus en plus poussée, ceci pour des raisons d'esthétique ou de multiplicité de fonctions. Cette miniaturisation rend les composants de plus en plus vulnérables aux agents extérieurs, atmosphère corrosive, poussières etc
D'où le besoin imperatif de fabriquer des montres dontltetan- chéité soit parfaite. Si ce problème est regle aisement en ce qui concerne l'assemblage du verrre sur le boitier, il n'en est pas de meme pour les boutons-poussoirs.Ceux-ci sont actuellement dotes de moyens d'étanchéité classiques tels que des joints toriques, des chicanes ou simplement des ajustements mécaniques "glissant juste". Ces moyens ne sont pas parfaits, et l'usure ou le vieillissement des pièces en mouvement finissent souvent par laisser des vides au travers desquels s'introduisent les poussières fines ou les brouillards, sources de corrosion, ou l'eau sous forte pression pour les montres de plongée. The micro-mechanisms and electronic circuits which constitute the active parts of such watches are subject to more and more miniaturization, this for reasons of aesthetics or multiplicity of functions. This miniaturization makes the components more and more vulnerable to external agents, corrosive atmosphere, dust, etc.
Hence the imperative need to manufacture watches with perfect water resistance. If this problem is easily resolved with regard to the assembly of the glass on the case, it is not the same for the push buttons. These are currently equipped with conventional sealing means such as O-rings , baffles, or just "just sliding" mechanical adjustments. These means are not perfect, and the wear or aging of moving parts often end up leaving voids through which fine dust or mists, sources of corrosion, or water under high pressure are introduced. diving watches.
Le bouton-poussoir selon l'invention permet d'éviter ces inconvénients. Il est en effet conçu de telle façon que son action se fasse à travers la masse du boitier de montre, sans qu'il soit nécessaire de réaliser des perforations au travers desquelles I agissent mécaniquement les boutons-poussoirs classiques. Cette absence de perforations dans le boitier règle donc d'une façon parfaite le problème de l'étanchéité. The push button according to the invention makes it possible to avoid these drawbacks. It is in fact designed in such a way that its action takes place through the mass of the watch case, without it being necessary to make perforations through which I mechanically act the conventional push buttons. This absence of perforations in the case therefore perfectly solves the problem of sealing.
Une pression manuelle sur le bouton-poussoir ne provoque pas un contact direct sur une lamelle conductrice du circuit électri que,mais provoque l'avancée d'un aimant qui, par sa proximité, va commandeur à distance le contact électrique proprement dit, celui-ci se trouvant à l'intérieur du boitier. Manual pressure on the push button does not cause direct contact on a conductive strip of the electrical circuit, but causes the advance of a magnet which, by its proximity, will remotely control the actual electrical contact, this located inside the box.
Le dessin annexé est une vue en coupe partielle d'une montre équipée d'un bouton-poussoir selon l'invention. The accompanying drawing is a partial sectional view of a watch fitted with a push button according to the invention.
Tel que représenté sur le dessin annexé, l'ensemble est disposé sur un boitier de montre 1, le poussoir 2 sur lequel une pression est exercée selon la flêche, entraîne un axe solidaire 3, à l'extremité duquel est fixé un aimant 4. Ces éléments sont guidés coaxialement par une pièce 5, celle-ci assurant en outre, par emboitement, la fixation de ce premier ensemble sur le boitier 1. Le mouvement de rappel est assuré par un ressort 6. As shown in the appended drawing, the assembly is arranged on a watch case 1, the pusher 2 on which pressure is exerted according to the arrow, drives an integral pin 3, at the end of which a magnet 4 is fixed. These elements are guided coaxially by a part 5, the latter also ensuring, by interlocking, the fixing of this first assembly on the housing 1. The return movement is ensured by a spring 6.
Ceci pour la partie menante a l'intérieur de la montre, un ensemble récepteur est dispose dans un boitier support 7. Celuici contient un second aimant 8, solidaire d'une lamelle oscillante 9, celle-ci étant à la fois articulée et "rappelée" au repos par l'effet élastique d'une goutte de "silicones" 10 ou produit aux caractéristiques s-imiiaires. This for the driving part inside the watch, a receiver assembly is placed in a support case 7. This contains a second magnet 8, integral with an oscillating strip 9, the latter being both articulated and "recalled "at rest by the elastic effect of a drop of" silicones "10 or product with similar characteristics.
Quand une pression est exercée sur le bouton-poussoir ex térieur, 1 'aimant 4 est amené en position avancée, telle que représentée en trait mixte fin, effleurant la zone amincie du boitier de montre 1. Notons que ce boitier est réalisé dans un materiau amagnètique, et que dans d'autre cas, il convient de rapporter dans la zône amincie de 1 une pastille ayant cette caractéristique. En cette position avancée, le champ magnétique traverse la masse du boitier 1, et provoque l'oscillation de la lamelle 9 elle-même menée par le recul de l'aimant 8 soumis au champ magnétique de 4.Dans cet exemple de réalisation, les aimants travaillent en opposition (même polarité face à face), ceci n' excluant pas la possibilite, selon une implantation différente, de faire travailler ces aimants en attraction. Notons aussi que l'utilisation d'aimants permanents anisotropes augmente sensiblement la performance de l'ensemble. Donc, l'oscillation provoquée de 8, 9, articulés en 10, permet le contact au niveau des picots 11, fermant ainsi un circuit quelconque. Ce peut être par exemple une alimentation électrique issue de la source d'énergie passant par le boitier 1, par l'intermédiaire d'un moyen 12, solidaire d'un circuit imprimé 13, à partir duquel est alimenté l'ensemble 8, 9 par un conducteur souple 14. When a pressure is exerted on the external push button, the magnet 4 is brought into the advanced position, as shown in thin dashed line, touching the thinned area of the watch case 1. It should be noted that this case is made of a material non-magnetic, and that in other cases, it is advisable to bring back in the thinned area of 1 a pellet having this characteristic. In this advanced position, the magnetic field crosses the mass of the housing 1, and causes the oscillation of the strip 9 itself driven by the recoil of the magnet 8 subjected to the magnetic field of 4. In this embodiment, the magnets work in opposition (same polarity face to face), this does not exclude the possibility, according to a different layout, of making these magnets work in attraction. Note also that the use of anisotropic permanent magnets significantly increases the performance of the assembly. Therefore, the oscillation caused by 8, 9, articulated at 10, allows contact at the level of the pins 11, thus closing any circuit. It can for example be a power supply from the energy source passing through the box 1, by means of a means 12, integral with a printed circuit 13, from which the assembly 8, 9 is supplied. by a flexible conductor 14.
Cette source duc'énergie est alors exploitable en 15 selon l'état du contact (ouvert ou fermé).This energy source can then be used at 15 depending on the state of the contact (open or closed).
Précisons qu'un tel bouton-poussoir ne necessite pas de modifications importantes pour doter des montres équipées de sys tèmes classiques. It should be noted that such a push button does not require any significant modifications to equip watches fitted with conventional systems.
Le bouton-poussoir objet de l'invention peut store utilisé dans tous les cas où un risque d'altération chimique ou un blocage mécanique peut apparattre compte tenu de la miniaturisation des composants utilisés, mais aussi dans le cas où l'on est en présence de pressions extérieures tres importantes. L'application la plus interessante de l'invention réside dans la solution apportée au problèmes d'étanchéité des montres et chronomètres, sans exclure les applications possibles sur tous les dispositifs comportant des boutons-poussoirs tels que claviers de calculateurs ou autres. The push button object of the invention can store used in all cases where a risk of chemical alteration or mechanical blockage may appear given the miniaturization of the components used, but also in the case where one is in the presence very high external pressures. The most interesting application of the invention lies in the solution provided to the problems of sealing watches and chronometers, without excluding the possible applications on all devices comprising push-buttons such as computer keyboards or others.
