Description

La présente invention se rapporte à un dispositif de fixation rapide d'un bracelet et plus particulièrement à un dispositif de fixation comportant une barrette élastique dont l'un des éléments est solidaire d'un bouton d'actionnement qui est disposé sous le bracelet et dont l'actionnement permet l'introduction ou l'enlèvement de la barrette dont l'une des extrémités est destinée à coopérer avec une ouverture de positionnement, une ouverture intermédiaire d'introduction et un trou qui sont pratiqués dans une des cornes d'une boîte de montre.The present invention relates to a device for quickly fixing a bracelet and more particularly to a fixing device comprising an elastic bar, one of the elements of which is integral with an actuation button which is arranged under the bracelet and whose actuation allows the introduction or removal of the bar, one end of which is intended to cooperate with a positioning opening, an intermediate introduction opening and a hole which are formed in one of the horns of a box of watch.

Les dispositifs de fixation de bracelets sont destinés à permettre un remplacement aisé des bracelets. Précédemment les bracelets de montre étaient remplacés pour des raisons d'usure ou de vieillissement et ces remplacements étaient peu fréquents ce qui ne nécessitait pas l'utilisation d'un dispositif de fixation rapide. Depuis plusieurs années, les fabricants proposent plusieurs types de bracelets pour la même montre et les remplacements deviennent beaucoup plus fréquents pour adapter à choix différents bracelets en fonction de l'utilisation, de la couleur ou de la mode. Il est donc devenu nécessaire que les utilisateurs puissent effectuer eux-mêmes un remplacement pratique et rapide des bracelets.The strap fixing devices are intended to allow easy replacement of the straps. Previously watch straps were replaced for reasons of wear or aging and these replacements were infrequent which did not require the use of a quick fastening device. For several years, manufacturers have been offering several types of straps for the same watch and replacements have become much more frequent in order to adapt different straps to suit different uses, colors or fashion. It therefore became necessary for the users to be able to carry out a practical and rapid replacement of the bracelets themselves.

De nombreuses formes d'exécutions de dispositifs de fixation de bracelets sont connues, mais elles présentent toutes des inconvénients. Les formes d'exécutions les plus connues et les plus répandues sont constituées par les barrettes élastiques simples, mais ces formes d'exécutions présentent l'inconvénient essentiel d'être peu pratique parce que l'enlèvement ou l'introduction des barrettes nécessite généralement l'utilisation d'un outil. Avec ces formes d'exécutions connues, il est possible d'enlever ou d'introduire les barrettes en utilisant un ongle mais la faible dimension des éléments rend cette opération très peu pratique et par conséquent inadéquate pour des remplacements fréquents. Des formes d'exécutions sont connues qui comportent un bouton d'actionnement de la barrette. Ces formes d'exécutions améliorent l'actionnement, mais elles ne permettent pas de résoudre le problème de la recherche d'un trou qui est pratiqué dans une corne de boîte de montre. Cette recherche est en effet rendue difficile par le fait qu'il est nécessaire de tirer sur le bouton dans une direction pour actionner la barrette et que simultanément il est nécessaire d'exercer des pressions dans d'autres directions pour rechercher la position du trou de la corne.Many forms of execution of bracelet fixing devices are known, but they all have drawbacks. The most well-known and widespread forms of execution consist of simple elastic bars, but these forms of execution have the essential drawback of being impractical because the removal or introduction of the bars generally requires use of a tool. With these known forms of execution, it is possible to remove or introduce the bars using a nail, but the small size of the elements makes this operation very impractical and therefore unsuitable for frequent replacement. Execution forms are known which include a button for actuating the bar. These forms of execution improve actuation, but they do not solve the problem of finding a hole which is made in a watch case horn. This search is in fact made difficult by the fact that it is necessary to pull the button in one direction to actuate the bar and that simultaneously it is necessary to exert pressure in other directions to search for the position of the hole. the Horn.

Une forme d'exécution connue par le brevet DE-U-91 14446 comporte une ouverture permettant d'améliorer quelque peu l'introduction de la barrette, mais cette forme d'exécution présente plusieurs inconvénients. Cette forme d'exécution comporte une ouverture en pente, et par ce fait seule une portion de l'ouverture présente une profondeur suffisante pour garantir un positionnement valable de l'extrémité de la barrette. Il est donc nécessaire d'actionner la barrette en comprimant le ressort de celle-ci pour atteindre une position dans laquelle l'extrémité de la barrette se trouve dans une position dans laquelle elle peut être positionnée valablement, ce qui présente l'inconvénient de nécessiter plusieurs actions simultanées. Dans la pratique, il faut tenir compte que les cornes sont généralement de faible hauteur, entre autre dans le cas des boîtes de montres plates ou extraplates, et que le très peu de place à disposition ne permet pas de réaliser une ouverture en pente procurant un positionnement valable. De plus, toujours en fonction de la faible hauteur des cornes et du peu de place à disposition, une ouverture en pente ne permet pas de procurer à la fois un positionnement valable, et une position intermédiaire d'introduction, ce qui implique qu'il est encore possible de rater le trou de la corne en exerçant une trop forte pression vers le haut. Dans la pratique, ce point est particulièrement important parce qu'il est pratiquement impossible de tirer fortement sur la barrette élastique sans exercer simultanément une pression importante vers le haut.An embodiment known from patent DE-U-91 14446 has an opening which makes it possible to improve the introduction of the bar somewhat, but this embodiment has several drawbacks. This embodiment has a sloping opening, and therefore only a portion of the opening has a sufficient depth to guarantee valid positioning of the end of the bar. It is therefore necessary to actuate the bar by compressing the spring thereof to reach a position in which the end of the bar is in a position in which it can be validly positioned, which has the drawback of requiring several simultaneous actions. In practice, it must be taken into account that the horns are generally of low height, among other things in the case of flat or extra-flat watch cases, and that the very little space available does not allow for a sloping opening providing a valid positioning. In addition, still depending on the low height of the horns and the limited space available, a sloping opening does not provide both valid positioning and an intermediate insertion position, which implies that is still possible to miss the hole of the horn by exerting too strong pressure up. In practice, this point is particularly important because it is practically impossible to pull strongly on the elastic bar without simultaneously exerting significant upward pressure.

Le but de la présente invention consiste donc à remédier aux inconvénients des formes d'exécutions connues.The object of the present invention therefore consists in remedying the drawbacks of the known embodiments.

Les buts sont atteints avec le principe de l'invention tel que décrit par la revendication 1.The objects are achieved with the principle of the invention as described by claim 1.

Le dispositif de fixation rapide d'un bracelet comporte, selon le principe de l'invention, une barrette élastique qui est constituée de deux éléments qui coulissent l'un dans l'autre et qui sont soumis à l'action d'un organe élastique de compression. Les extrémités de la barrette sont destinées à coopérer, en position de service, avec des trous qui sont pratiqués dans les cornes de la boîte de montre. Une des cornes comporte une ouverture de positionnement qui est pratiquée dans la face inférieure de la corne et une ouverture intermédiaire d'introduction qui est pratiquée dans la face intérieure verticale de la corne. Un des éléments de la barrette est solidaire d'un bouton d'actionnement qui est disposé sous le bracelet, et l'extrémité de cet élément est destiné à coopérer avec les ouvertures pratiquées dans la corne. Le montage de la barrette s'effectue en installant une des extrémités de la barrette dans la corne qui comporte un trou correspondant, en introduisant l'autre extrémité de la barrette dans l'ouverture de positionnement, en tirant sur le bouton pour introduire cette extrémité dans l'ouverture intermédiaire, et en introduisant cette extrémité dans le trou de la corne qui comporte les ouvertures, par une légère pression vers le haut.
Cette forme d'exécution présente de nombreux avantages. Un des avantages est constitué par le fait que le positionnement de l'extrémité dans l'ouverture de positionnement s'effectue sans avoir à actionner le bouton de la barrette, ce qui facilite d'une manière importante la recherche à l'aveugle de cette ouverture. Le bouton est alors actionné jusqu'à ce que l'extrémité de la barrette passe dans l'ouverture intermédiaire, et dès que l'extrémité est engagée dans cette ouverture, il n'est plus nécessaire de continuer à tirer sur le bouton ce qui présente l'avantage de pouvoir contrôler la pression exercée vers le haut. Un autre avantage est constitué par le fait que l'ouverture intermédiaire est en retrait par rapport à la face verticale intérieure de la corne et par conséquent par rapport à la partie supérieure du trou de la corne, c'est-à-dire que même en exerçant une trop forte pression vers le haut, l'extrémité de la barrette vient en butée sur la partie supérieure du trou ce qui supprime les possibilités de ratage. L'ouverture de positionnement est pratiquée, sur toute sa longueur, à la même profondeur, et cette profondeur nécessaire à un bon positionnement est faible en fonction du fait que l'extrémité de la barrette est engagée sur une longueur suffisante. Cette faible profondeur nécessaire permet de pratiquer l'ouverture de positionnement dans tous les types de cornes, y compris les cornes de très faibles hauteurs des montres extraplates.The device for fastening a bracelet comprises, according to the principle of the invention, an elastic bar which is made up of two elements which slide one inside the other and which are subjected to the action of an elastic member. compression. The ends of the bar are intended to cooperate, in the service position, with holes which are made in the horns of the watch case. One of the horns has a positioning opening which is made in the underside of the horn and an intermediate introduction opening which is made in the vertical inner face of the horn. One of the elements of the bar is integral with an actuation button which is arranged under the bracelet, and the end of this element is intended to cooperate with the openings made in the horn. The assembly of the bar is carried out by installing one of the ends of the bar in the horn which has a corresponding hole, by introducing the other end of the bar into the positioning opening, by pulling on the button to introduce this end in the intermediate opening, and by introducing this end into the hole of the horn which comprises the openings, by a slight pressure upwards.
This embodiment has many advantages. One of the advantages is that the positioning of the end in the positioning opening is carried out without having to actuate the button of the bar, which facilitates importantly blind research of this openness. The button is then actuated until the end of the bar passes into the intermediate opening, and as soon as the end is engaged in this opening, it is no longer necessary to continue to pull the button which has the advantage of being able to control the pressure exerted upwards. Another advantage is constituted by the fact that the intermediate opening is set back with respect to the internal vertical face of the horn and consequently with respect to the upper part of the hole of the horn, that is to say that even by exerting too much upward pressure, the end of the bar abuts on the upper part of the hole which eliminates the possibility of failure. The positioning opening is made, over its entire length, at the same depth, and this depth necessary for good positioning is small depending on the fact that the end of the bar is engaged over a sufficient length. This small depth required makes it possible to practice the positioning aperture in all types of horns, including horns of very low heights in extra-flat watches.

La figure 5 est une vue de détail de côté d'une des cornes constituant le dispositif de fixation.Figure 5 is a detail side view of one of the horns constituting the fixing device.

En référence tout d'abord aux figures 1 et 2, une barrette élastique est constituée par deux éléments principaux, un axe 1 et une tige 2 qui est montée coulissante dans un trou cylindrique 3 qui est pratiqué dans l'axe 1. Un organe élastique 4 est monté dans le trou cylindrique 3 et agit en compression contre le fond du trou cylindrique et contre l'extrémité intérieure de la tige 2. L'organe élastique 4 peut être constitué par un ressort. L'axe 1 est monté dans l'une des extrémités d'un des éléments d'un bracelet 5. L'axe 1 comporte une tige 10 dont l'extrémité présente une forme semi-sphérique. La tige 10 est destinée à coopérer avec un trou 11 qui est pratiqué dans la face verticale intérieure d'une corne à trou 12 d'une boîte de montre 18. La partie extérieure 14 de la tige 2 est destinée à coopérer, en position fermée, avec un trou 13 qui est pratiqué dans la face verticale intérieure d'une corne à ouvertures 15. Une ouverture de positionnement 17, de forme semi-cylindrique, est pratiquée dans la face horizontale inférieure de la corne 15. La longueur de l'ouverture est déterminée en fonction de la longueur de la barrette lorsque celle-ci n'est pas actionnée et de manière à ce que l'extrémité de la barrette se trouve complètement introduite dans l'ouverture, dans cette position. l'ouverture de positionnement 17 est d'égale profondeur sur toute sa longueur. L'extrémité 14 de la tige 2 est destinée à coopérer avec l'ouverture de positionnement 17 dans la position de positionnement. Une ouverture intermédiaire d'introduction 16, de forme semi-cylindrique, est pratiquée dans la face verticale intérieure de la corne 15. Cette ouverture intermédiaire d'introduction 16 est pratiquée depuis la face horizontale inférieure de la corne 15 jusqu'au trou 13.
Une tige d'actionnement 8 est fixée sur la tige 2, perpendiculairement à celle-ci. La tige d'actionnement est disposée dans une ouverture 6 qui est pratiquée dans l'axe 1 et dans une ouverture 7 qui est pratiquée dans le bracelet 5. L'extrémité de la tige d'actionnement 8 comporte un bouton d'actionnement 9 qui est disposé sous le bracelet 5, et qui est destiné à être actionné par le doigt d'un utilisateur, par exemple.Referring firstly to Figures 1 and 2, an elastic bar is constituted by two main elements, an axis 1 and a rod 2 which is slidably mounted in a cylindrical hole 3 which is formed in the axis 1. An elastic member 4 is mounted in the cylindrical hole 3 and acts in compression against the bottom of the cylindrical hole and against the inner end of the rod 2. The elastic member 4 can be constituted by a spring. The axis 1 is mounted in one of the ends of one of the elements of a bracelet 5. The axis 1 comprises a rod 10, the end of which has a semi-spherical shape. The rod 10 is intended to cooperate with a hole 11 which is made in the inner vertical face of a horn with a hole 12 of a watch case 18. The outer part 14 of the rod 2 is intended to cooperate, in the closed position , with a hole 13 which is made in the inner vertical face of a horn with openings 15. A positioning opening 17, of semi-cylindrical shape, is made in the lower horizontal face of the horn 15. The length of the opening is determined according to the length of the bar when it is not actuated and so that the end of the bar is completely inserted into the opening, in this position. the positioning opening 17 is of equal depth over its entire length. The end 14 of the rod 2 is intended to cooperate with the positioning opening 17 in the positioning position. An intermediate introduction opening 16, of semi-cylindrical shape, is made in the inner vertical face of the horn 15. This intermediate introduction opening 16 is made from the lower horizontal face of the horn 15 to the hole 13.
An actuating rod 8 is fixed on the rod 2, perpendicular thereto. The actuating rod is disposed in an opening 6 which is formed in the axis 1 and in an opening 7 which is formed in the bracelet 5. The end of the actuating rod 8 comprises an actuating button 9 which is disposed under the bracelet 5, and which is intended to be actuated by the finger a user, for example.

La figure 3 montre la position de positionnement, c'est-àdire la position dans laquelle l'utilisateur installe l'extrémité d'un élément de bracelet dans les cornes de la boîte de montre. La première phase consiste à introduire la tige 10 dans le trou 11 de la corne 12. Par pression vers le haut d'un doigt sur le bracelet 5 ou sur le bouton 9, l'extrémité 14 de la tige 2 est disposée dans l'ouverture de positionnement 17 qui est pratiquée dans la face horizontale inférieure de la corne 15.
L'ouverture de positionnement permet à l'utilisateur de trouver facilement la bonne position d'introduction à l'aveugle, sans qu'il soit nécessaire d'actionner le bouton 9.Figure 3 shows the positioning position, that is to say the position in which the user installs the end of a strap element in the horns of the watch case. The first phase consists in introducing the rod 10 into the hole 11 of the horn 12. By pressing an finger upwards on the bracelet 5 or on the button 9, the end 14 of the rod 2 is placed in the positioning opening 17 which is formed in the lower horizontal face of the horn 15.
The positioning opening allows the user to easily find the correct insertion position for the blind, without having to press button 9.

La figure 4 montre la position d'introduction. Dans cette position, la tige 10 reste introduite dans le trou 11 de la corne 12. Le bouton 9 est actionné par un doigt de manière à faire coulisser la tige 2 vers l'intérieur, ce qui a pour effet de compresser l'organe élastique 4 qui est disposé dans le trou cylindrique 3. Par une pression simultanée exercée sur le bouton vers le haut, l'extrémité 14 de la tige 2 est introduite et maintenue en position dans l'ouverture intermédiaire d'introduction 16, jusqu'à ce qu'elle s'introduise dans le trou 13, c'est-à-dire dans la position fermée montrée sur les figures 1 et 2. L'extrémité 14 vient automatiquement en butée contre la partie supérieure du trou cylindrique 3.Figure 4 shows the insertion position. In this position, the rod 10 remains inserted in the hole 11 of the horn 12. The button 9 is actuated by a finger so as to slide the rod 2 inwards, which has the effect of compressing the elastic member 4 which is arranged in the cylindrical hole 3. By a simultaneous pressure exerted on the button upwards, the end 14 of the rod 2 is introduced and held in position in the intermediate introduction opening 16, until that it is introduced into the hole 13, that is to say in the closed position shown in FIGS. 1 and 2. The end 14 automatically comes into abutment against the upper part of the cylindrical hole 3.

En référence aux figures 1 et 2, l'enlèvement du bracelet s'effectue en actionnant le bouton d'actionnement 9 de manière à désengager l'extrémité 14 de la tige 2 du trou 13.With reference to FIGS. 1 and 2, the bracelet is removed by actuating the actuation button 9 so as to disengage the end 14 of the rod 2 from the hole 13.

La figure 5 montre en détail l'ouverture de positionnement 17 qui est pratiquée dans la face horizontale inférieure de la corne 15 qui est solidaire de la boîte de montre 18, et l'ouverture d'introduction 16 qui est pratiquée dans la face verticale intérieure de la corne 15, depuis la face horizontale inférieure de la corne jusqu'au trou 13.Figure 5 shows in detail the positioning opening 17 which is formed in the lower horizontal face of the horn 15 which is integral with the watch case 18, and the introduction opening 16 which is formed in the inner vertical face of the horn 15, from the lower horizontal face of the horn up to hole 13.

Les trous et ouvertures semi-sphériques présentent des rayons et diamètres qui sont égaux avec jeux au rayon et au diamètre des extrémités de la barrette.The semi-spherical holes and openings have radii and diameters which are equal with play at the radius and the diameter of the ends of the bar.

Les matières utilisées pour la réalisation du dispositif de fixation sont indépendantes du principe de l'invention. Les axes, tiges, cornes et boîte de montre peuvent être réalisés en matériaux ferreux ou non ferreux, en matériaux nobles tels que l'or par exemple, ainsi qu'en matières plastiques, composites ou céramiques, à titre d'exemples.The materials used to make the fixing device are independent of the principle of the invention. The axes, rods, horns and watch case can be made of ferrous or non-ferrous materials, of noble materials such as gold for example, as well as plastics, composites or ceramics, by way of examples.

Les matières utilisées pour la réalisation du bracelet sont indépendantes du principe de l'invention, le dispositif de fixation pouvant être adapté à tous les bracelets réalisés dans les matériaux les plus divers, ceci en tenant compte que si les bracelets sont réalisés en matières non déformables, un jeu de fonctionnement doit être prévu entre le bracelet et les cornes.The materials used for the production of the bracelet are independent of the principle of the invention, the fixing device being able to be adapted to all the bracelets produced in the most diverse materials, this taking into account that if the bracelets are produced in non-deformable materials , an operating clearance must be provided between the bracelet and the lugs.
