Description

La présente invention concerne une barrette de fixation rapide d'un bracelet de montre et plus particulièrement une telle barrette de fixation d'un bracelet aux cornes ou aux pièces d'attache d'une boíte de montre, ce dispositif de fixation permettant notamment d'interchanger le bracelet de façon simple sans risquer d'endommager la boíte et/ou le bracelet.The present invention relates to a strip of quick fastening of a watch strap and more particularly such a bar for fixing a bracelet with horns or attachments from a box of shows, this fixing device allowing in particular to easily interchange the bracelet without risking damage the case and / or the bracelet.

La présente invention concerne également une montre munie d'une barrette telle que définie ci-dessus.The present invention also relates to a watch fitted with a bar as defined above.

Généralement, les bracelets de montre sont fixés sur les boítes de montre à cornes au moyen de barrettes sur lesquelles sont adaptés les brins du bracelet, les extrémités des barrettes étant fixées aux cornes de la boíte de montre. Les barrettes utilisées le plus couramment sont dites barrettes à ressort et comprennent à leurs extrémités deux pivots. Généralement, les pivots sont mobiles à l'intérieur d'un tube central et sont soumis à l'action d'un ressort logé à l'intérieur du tube et qui les pousse vers l'extérieur, les cornes étant munies respectivement de trous dans lesquels pénètrent les pivots de la barrette.Generally, watch straps are attached to watch boxes with horns by means of bars on which are the strands of the bracelet, the ends of the bars being fixed to the horns of the watch case. The most used bars commonly are called spring bars and include their ends two pivots. Generally the pivots are movable inside a central tube and are subjected to the action of a spring housed inside the tube and pushes them outwards, the horns being respectively provided with holes into which the bar pivots.

Un tel système de fixation du bracelet sur la boíte présente l'inconvénient de nécessiter généralement l'intervention d'un spécialiste pour démonter le bracelet lorsque ce dernier doit être remplacé par un autre. En outre, cette opération de démontage est réalisée à l'aide d'un outil, par exemple des brucelles ou un couteau, qui risque de blesser la boíte de montre. Ce système n'est par conséquent pas très satisfaisant et ne répond pas aux exigences actuelles du marché qui demande des dispositifs de fixation de bracelet permettant aux utilisateurs eux-mêmes de remplacer facilement leur bracelet par un autre. Il est par exemple utile de pouvoir transformer une montre de ville en montre de plongée portée par-dessus une combinaison, et pour laquelle il est donc nécessaire d'adapter un bracelet de plus grande longueur acheté comme accessoire. On peut également souhaiter à tout moment de la journée adapter le type de sa montre-bracelet au gré des circonstances et donc pouvoir soi-même facilement changer le bracelet, par exemple pour avoir un bracelet assorti à la couleur de ses vêtements.Such a system for attaching the bracelet to the box has the disadvantage of generally requiring the intervention of a specialist to disassemble the bracelet when the latter must be replaced by another. In in addition, this disassembly operation is carried out using a tool, such as tweezers or a knife, which risk of injuring the watch case. This system is not therefore not very satisfactory and does not respond to current market demands for devices bracelet attachment allowing users themselves easily replace their bracelet with another. It is for example useful to be able to transform a watch in a diving watch worn over a combination, and for which it is therefore necessary to adapt a longer bracelet bought as accessory. We can also wish at any time to the day adapt the type of your wristwatch to suit circumstances and therefore be able to easily yourself change the bracelet, for example to have a bracelet match the color of his clothes.

Une solution consistant à munir le pivot mobile de la barrette d'un ergot de manipulation pouvant être actionné sans l'aide d'un outil pour démonter le bracelet a déjà été proposée dans la demande de brevet WO 94/14105.A solution consisting in providing the movable pivot with the bar of a manipulating lug which can be actuated without using a tool to disassemble the bracelet has already was proposed in patent application WO 94/14105.

Cette solution n'est toutefois pas satisfaisante car elle est limitée aux bracelets en cuir et ne permet pas l'utilisation de bracelets en cuir classiques, mais nécessite un bracelet comprenant une découpe supplémentaire dans des oeillets recevant les barrettes. Par ailleurs, le montage et le démontage du bracelet nécessitent notamment d'amener le pivot mobile de la barrette dans le trou de la corne tout en le maintenant rétracté par l'intermédiaire de l'ergot avec l'ongle. Là encore, cette opération requiert une certaine dextérité et ne peut par conséquent être mise en oeuvre par tout utilisateur. Par ailleurs, cette opération oblige l'utilisateur d'exercer une force relativement grande sur l'ergot au risque de se faire mal, voire de se casser l'ongle.However, this solution is not satisfactory because it is limited to leather bracelets and does not allow the use of classic leather bracelets but requires a bracelet including a cutout additional in eyelets receiving the bars. In addition, the assembly and disassembly of the bracelet require in particular to bring the movable pivot of the bar in the hole of the horn while holding it retracted via the lug with the nail. The again, this operation requires a certain dexterity and cannot therefore be implemented by all user. In addition, this operation requires the user to exert a relatively large force on the lug at the risk of getting hurt or even breaking the nail.

L'invention a donc pour but principal de remédier aux inconvénients de l'art antérieur susmentionné en fournissant une barrette de fixation rapide d'un bracelet de montre, sûre et peu coûteuse, qui puisse être mise en oeuvre aisément par l'utilisateur lui-même, qui s'adapte à n'importe quel type de bracelet et qui ne nuise pas à l'esthétique de l'ensemble de la montre.The main aim of the invention is therefore to remedy the disadvantages of the aforementioned prior art in providing a quick fastening bar for a bracelet watch, safe and inexpensive, which can be set up works easily by the user himself, who adapts to any type of bracelet and which does not harm the aesthetics of the entire watch.

A cet effet l'invention a pour objet une barrette de fixation d'un bracelet de montre destinée à être engagée à coulissement dans un passage d'une boíte de montre et montée dans une des extrémités d'un bracelet, ladite barrette comprenant un corps longiligne et étant caractérisée en ce qu'elle comprend un dispositif de verrouillage, ledit dispositif de verrouillage comprenant un verrou soumis à l'action d'un organe élastique et des moyens de commande dudit verrou qui sont accessibles depuis une extrémité de la barrette, ledit verrou étant agencé de manière à faire saillie transversalement audit corps hors dudit corps de ladite barrette, dans une première position dans laquelle les moyens de commande ne sont pas actionnés, et à se rétracter à l'intérieur dudit corps, dans une deuxième position lorsque les moyens de commande sont actionnés.To this end the invention relates to a bar of attachment of a watch strap intended to be used for sliding in a passage of a watch case and mounted in one end of a bracelet, said bar comprising a slender body and being characterized in that it comprises a device for locking, said locking device comprising a lock subjected to the action of an elastic member and means for controlling said lock which are accessible from one end of the bar, said lock being arranged to project transversely into said audit body outside said body of said bar, in a first position in which the control means do not are not actuated, and to retract inside said body, in a second position when the means of control are activated.

Ainsi, l'utilisateur peut aisément démonter ou remonter son bracelet à fixation à barrette sur une boíte de montre, par exemple en vue de son changement, en agissant simplement sur les moyens de commande pour dégager le verrou de moyens complémentaires ménagés sur la boíte, et retirer latéralement la barrette par un simple mouvement de coulissement parallèle à son axe longitudinal. Cette opération présente l'avantage important de pouvoir être effectuée sans recours à un spécialiste et sans aucun outillage.Thus, the user can easily disassemble or reassemble its strap with bar fixing on a box watch, for example with a view to changing it, simply acting on the control means for release the lock of additional means provided on the box, and laterally remove the bar with a simple sliding movement parallel to its axis longitudinal. This operation has the advantage important to be able to be carried out without recourse to a specialist and without any tools.

Selon une caractéristique avantageuse de l'invention, les moyens de commande comprennent une tige de commande montée coulissante relativement audit corps, une première extrémité de la tige de commande étant associée à des moyens d'actionnement et une deuxième extrémité étant associée audit verrou, ledit organe élastique agissant directement sur ladite tige de commande.According to an advantageous characteristic of the invention, the control means include a control rod sliding rise relatively to said body, a first end of the control rod being associated with actuating means and a second end being associated with said lock, said elastic member acting directly on said control rod.

Selon une autre caractéristique avantageuse, ledit verrou est formé d'un élément allongé comprenant une partie d'accrochage qui fait saillie hors dudit corps longiligne dans ladite première position, et ledit élément allongé est articulé par rapport à la tige de commande.According to another advantageous characteristic, said lock is formed by an elongated element comprising a hooking part which projects out of said body elongated in said first position, and said element elongated is articulated with respect to the control rod.

L'invention a également pour objet une montre comprenant une barrette telle que définie ci-dessus.The invention also relates to a watch comprising a bar as defined above.

D'autres caractéristiques et avantages de l'invention apparaítront plus clairement à lecture de la description suivante d'un mode de réalisation de l'invention donné à titre purement illustratif et non limitatif, cette description étant faite en liaison avec les dessins dans lesquels :

  • la figure 1 est une coupe longitudinale d'un mode de réalisation d'une barrette de fixation selon l'invention, le verrou du dispositif de verrouillage étant représenté dans une première position dite de travail, ladite barrette étant montée sur les cornes d'une boíte de montre, et
  • la figure 2 est une coupe similaire à celle représentée à la figure 1 dans laquelle le verrou est représenté dans une deuxième position dite de retrait.
Other characteristics and advantages of the invention will appear more clearly on reading the following description of an embodiment of the invention given purely by way of non-limiting illustration, this description being made in conjunction with the drawings in which:
  • Figure 1 is a longitudinal section of an embodiment of a fixing bar according to the invention, the latch of the locking device being shown in a first so-called working position, said bar being mounted on the horns of a watch case, and
  • Figure 2 is a section similar to that shown in Figure 1 wherein the latch is shown in a second position called withdrawal.

En se référant aux figures 1 et 2, on voit une vue partielle d'une montre-bracelet représentée partiellement en coupe et désignée pas la référence générale 1. La montre-bracelet 1 comporte une boíte de montre 2 à laquelle est attaché de façon articulée une extrémité d'un bracelet 4 à l'aide d'une barrette de fixation 6.Referring to Figures 1 and 2, we see a view partial of a wristwatch partially shown in section and designated by the general reference 1. The wristwatch 1 has a watch case 2 to which is hingedly attached to one end of a bracelet 4 using a fixing bar 6.

Le terme bracelet dans ce contexte comprend tout type de bracelet pouvant être attaché à la boíte à l'aide de barrettes pour maintenir en position la montre sur le poignet d'un utilisateur et comprend non seulement les bracelets en cuir ou en plastique, mais aussi les bracelets métalliques, par exemple à maillons.The term bracelet in this context includes all types bracelet that can be attached to the box using bars to keep the watch in position on the wrist of a user and includes not only the leather or plastic bracelets, but also metal bracelets, for example with links.

La boíte 2 comprend de façon classique une carrure munie de deux paires de cornes de fixation du bracelet 4 et dont seules les cornes 8 et 10 d'une paire sont représentées au dessin. Les deux paires de cornes sont placées, de façon classique sur des côtés opposés de la carrure, à 12 heures et à 6 heures.The box 2 conventionally comprises a middle part fitted with two pairs of strap fixing lugs 4 and of which only the horns 8 and 10 of a pair are shown in the drawing. The two pairs of horns are conventionally placed on opposite sides of the middle, 12 o'clock and 6 o'clock.

Par cornes, on comprendra dans le contexte de l'invention tout élément de formes variées, servant à attacher le bracelet à la boíte de montre. Ces cornes peuvent épouser la forme générale de la carrure, mais pas nécessairement. On notera que les éléments d'attache se rattachant peu ou pas à la carrure, ou encore rapportés sur la boíte, sont également compris dans cette définition générale des cornes.By horns, we will understand in the context of the invention any element of various forms, serving to attach the strap to the watch case. These horns can match the general shape of the middle, but not necessarily. Note that the attachment elements are attaching little or no to the middle, or even reported on the box, are also included in this definition general horns.

Pour des raisons de simplification, on ne décrira la barrette 6 qu'en liaison avec la fixation d'un brin ou d'une extrémité du bracelet 4 à une paire de cornes 8 et 10, la barrette de fixation du bracelet sur l'autre paire de cornes étant réalisée de façon identique.For reasons of simplification, we will not describe the bar 6 only in connection with the attachment of a strand or from one end of the bracelet 4 to a pair of horns 8 and 10, the strap for fixing the bracelet to the other pair of horns being produced identically.

L'extrémité du bracelet 4, représenté en traits mixtes, est associée à la barrette de fixation 6 à l'aide de laquelle elle est fixée aux cornes 8 et 10. La barrette 6 est engagée d'une part dans un passage formé par deux ouvertures 12, 14 perpendiculaires à la direction longitudinale du bracelet et ménagées respectivement dans les cornes 8 et 10 et d'autre part dans un oeillet 16 prévu à l'extrémité du bracelet 4, l'extrémité du bracelet s'étendant dans l'espace séparant les cornes 8 et 10.The end of bracelet 4, shown in lines mixed, is associated with the fixing bar 6 using from which it is fixed to the horns 8 and 10. The bar 6 is engaged on the one hand in a passage formed by two openings 12, 14 perpendicular to the direction longitudinal of the bracelet and arranged respectively in horns 8 and 10 and on the other hand in an eyelet 16 provided at the end of bracelet 4, the end of bracelet extending in the space separating the horns 8 and 10.

Selon l'invention, la barrette 6 comprend un corps longiligne 18 formé dans l'exemple représenté par un tube fermé à une de ses extrémité par un fond 20.According to the invention, the bar 6 comprises a body elongated 18 formed in the example represented by a tube closed at one end by a bottom 20.

Le tube 20 comprend une première partie 22 ayant un premier diamètre suivie d'une deuxième partie 24 d'un deuxième diamètre supérieur au premier et délimitée par un épaulement 26. La partie 22 s'étend sensiblement entre les cornes 8 et 10 et la partie 24 est s'étend dans l'ouverture 14 qui présente une forme correspondante.The tube 20 comprises a first part 22 having a first diameter followed by a second part 24 of a second diameter greater than the first and delimited by a shoulder 26. Part 22 extends substantially between the horns 8 and 10 and part 24 is extends in the opening 14 which has a corresponding shape.

La barrette 6 comprend en outre un dispositif de verrouillage de celle-ci sur les cornes 8 et 10.The bar 6 further comprises a device for locking it on the horns 8 and 10.

Ce dispositif de verrouillage comprend un verrou 28 soumis à l'action d'un organe élastique 30 et des moyens de commande 32 du verrou. Les moyens de commande 32 comprennent une tige de commande qui s'étend à l'intérieur du tube 22 et qui est montée coulissante par rapport à ce dernier.This locking device comprises a lock 28 subjected to the action of an elastic member 30 and means 32 of the lock. Control means 32 include a control rod that extends inside of tube 22 and which is slidably mounted relative to this latest.

Dans l'exemple représenté, l'organe élastique 30 agit sur le verrou 28 par l'intermédiaire de la tige de commande 32, l'organe élastique 30 s'étendant entre le fond 20 du tube 22 et une extrémité 34 de la tige 32. Cet organe élastique 30 est formé par un ressort hélicoïdal qui agit directement sur la tige de commande 32 pour la repousser vers l'extérieur du tube 20. On notera à ce propos que l'extrémité 34 est munie d'un téton de centrage (non référencé) du ressort 30.In the example shown, the elastic member 30 acts on the latch 28 via the rod control 32, the elastic member 30 extending between the bottom 20 of tube 22 and one end 34 of rod 32. This elastic member 30 is formed by a helical spring which acts directly on the control rod 32 for the push back towards the outside of the tube 20. It will be noted at this about that the end 34 is provided with a centering pin (not referenced) of spring 30.

L'extrémité opposée de la tige 32 fait saillie à l'extérieur du tube 22. Cette extrémité est conformée en un bouton-poussoir 36 qui forme des moyens d'actionnement de la tige 32. Les moyens de commande de la tige sont ainsi accessibles depuis l'extérieur du tube.The opposite end of the rod 32 projects the outside of the tube 22. This end is shaped as a push button 36 which forms actuation means rod 32. The rod control means are thus accessible from outside the tube.

L'extrémité 34 est associée au dispositif de verrouillage qui est agencé pour que le verrou 28 fasse saillie transversalement par rapport à l'axe longitudinal A-A du tube 22 et hors de ce dernier dans une première position dite position de travail, représentée à la figure 1, lorsque la tige de commande 32 n'est pas actionnée, et à s'escamoter complètement à l'intérieur du tube 22 dans une deuxième position dite position de retrait, représentée à la figure 2, lorsque la tige de commande 30 est actionnée par le bouton poussoir 28.The end 34 is associated with the device for lock which is arranged so that the lock 28 makes protruding transversely to the longitudinal axis A-A of tube 22 and out of it in a first so-called working position, shown in the figure 1, when the control rod 32 is not actuated, and to retract completely inside the tube 22 in a second position called the withdrawal position, shown in Figure 2, when the control rod 30 is actuated by push button 28.

Dans le mode de réalisation décrit, le verrou 28 est formé d'un élément allongé qui est logé dans un évidement 38 ménagé dans la tige 32 et dans lequel il peut s'escamoter complètement. Le verrou 28 comprend, à une extrémité libre (à droite sur les figures), une partie d'accrochage 40 reliée, par l'intermédiaire d'une partie médiane allongée 42, à une partie d'articulation 44 située à son extrémité opposée.In the embodiment described, the latch 28 is formed of an elongated element which is housed in a recess 38 formed in the rod 32 and in which it can retract completely. The latch 28 includes, at one free end (on the right in the figures), part hooking 40 connected, via a part median elongated 42, at a hinge part 44 located at its opposite end.

La partie d'accrochage 40 fait saillie à travers une ouverture oblongue 46 ménagée à cet effet dans le tube 22, lorsque la tige de commande 32 est en position de travail. Cette partie d'accrochage 40 s'appuie contre des moyens complémentaires formés, dans l'exemple représenté, par une des parois 48 des cornes se trouvant en regard, pour bloquer longitudinalement la barrette 6 dans les passages 12 et 14 et assurer la fixation du bracelet 4.The hooking part 40 projects through a oblong opening 46 made for this purpose in the tube 22, when the control rod 32 is in the working position. This attachment portion 40 is supported against means formed, in the example shown, by a walls 48 of the horns lying opposite, for longitudinally block the bar 6 in the passages 12 and 14 and secure the bracelet 4.

La partie d'articulation 44 s'étend dans un premier logement 50 prévu à une extrémité de l'évidement 38 et est articulée par rapport à la tige 32 sur une goupille 52 solidaire du tube 22. La goupille 52 s'étend perpendiculairement à l'axe A-A du tube et traverse deux ouvertures oblongues 54 (dont seule une est visible au dessin) ménagés en regard l'une de l'autre des parois latérales de la tige 32, ces ouvertures débouchant dans le premier logement 50 et s'étendant parallèlement à l'axe A-A.The articulation part 44 extends in a first housing 50 provided at one end of the recess 38 and is articulated with respect to the rod 32 on a pin 52 integral with the tube 22. The pin 52 extends perpendicular to the axis A-A of the tube and crosses two oblong openings 54 (only one of which is visible on the drawing) arranged opposite one another of the walls lateral of the rod 32, these openings opening into the first housing 50 and extending parallel to the axis A-A.

Un deuxième logement 56 prévu dans l'évidement 38, reçoit la partie d'accrochage 40 lorsque la tige 32 est dans la deuxième position. Ce deuxième logement 56 est situé en regard de l'ouverture oblongue 46 prévue dans le tube 22 pour que la partie d'accrochage 40 puisse faire saillie hors du tube 22 dans la première position (figure 1).A second housing 56 provided in the recess 38, receives the hooking part 40 when the rod 32 is in the second position. This second housing 56 is located opposite the oblong opening 46 provided in the tube 22 so that the hooking part 40 can make protrusion from the tube 22 in the first position (figure 1).

Un épaulement 58 qui s'étend entre le premier logement 50 et le deuxième logement 56 est par ailleurs prévu pour que le verrou 28, en particulier la partie d'accrochage 40, soit bloqué par cet épaulement lorsque le verrou 28 est dans la position de travail (figure 1).A shoulder 58 which extends between the first housing 50 and the second housing 56 is also provided for the latch 28, in particular the part attachment 40, or blocked by this shoulder when the latch 28 is in the working position (Figure 1).

Dans l'exemple décrit, la partie d'accrochage 40 présente une forme générale polygonale convexe en section longitudinale et comprenant notamment une base plane 60 par laquelle elle repose sur l'épaulement 58 dans la première position.In the example described, the attachment portion 40 has a general polygonal convex shape in section longitudinal and comprising in particular a flat base 60 by which it rests on the shoulder 58 in the first position.

Cette partie d'accrochage comprend en outre dans sa partie distale une face de retenue 62 qui s'étend sensiblement perpendiculairement à la partie médiane 42 et qui s'appuie contre la paroi 48 sous l'effet du ressort 30 dans la position de travail. La face 62 se prolonge par une face 64 de glissement ou de came qui est inclinée par rapport à l'axe A-A. La face 64 forme avec l'axe A-A un angle β qui est compris entre 20° et 80° et de façon préférée de l'ordre de 45°. La face 64 permet au verrou 28 d'être amené dans la position de retrait (figure 2) par glissement de cette face 54 sur une paroi 66 du deuxième logement 56 lorsque on l'on agit sur la tige de commande 32 via les moyens d'actionnement 38. Cette paroi 66 comprend une forme correspondante à celle de la partie distale de la partie d'accrochage 40, à savoir une portion sensiblement perpendiculaire à l'axe A-A et une portion inclinée.This attachment part further comprises in its distal part a retaining face 62 which extends substantially perpendicular to the middle part 42 and which leans against the wall 48 under the effect of the spring 30 in the working position. Face 62 is extended by a sliding or cam face 64 which is inclined by relative to axis A-A. The face 64 forms with the axis A-A a angle β which is between 20 ° and 80 ° and so preferred of the order of 45 °. Face 64 allows lock 28 to be brought into the withdrawal position (Figure 2) by sliding of this face 54 on a wall 66 of the second housing 56 when acting on the control rod 32 via the actuating means 38. This wall 66 includes a shape corresponding to that of the part distal of the attachment portion 40, namely a portion substantially perpendicular to the axis A-A and a portion inclined.

La partie d'accrochage 40 présente dans sa partie proximale inférieure, c'est-à-dire la partie la plus proche de l'épaulement 58, une autre face 68 de glissement ou came sensiblement parallèle à la face 64. Cette face 68 permet au verrou 28, et plus particulièrement à la partie d'accrochage 40, d'être amené dans le deuxième logement 56 (dans la deuxième position) par glissement de cette face 68 contre le bord 70 de l'épaulement 58 lorsque l'on agit sur la tige 22. Cela permet d'escamoter complètement le verrou 28 dans l'évidement 38. La face 68 permet également à l'épaulement 58 de repousser la partie d'accrochage 40 vers l'extérieur du tube 22 quand on relâche le bouton-poussoir 38.The attachment part 40 present in its part proximal inferior, i.e. the most close to shoulder 58, another sliding face 68 or cam substantially parallel to face 64. This face 68 allows the lock 28, and more particularly to the part hook 40, to be brought into the second housing 56 (in the second position) by sliding this face 68 against the edge 70 of the shoulder 58 when acting on the rod 22. This makes it possible to completely retract the latch 28 in the recess 38. The face 68 also allows at the shoulder 58 to push back the hooking part 40 towards the outside of the tube 22 when the push button is released 38.

Ainsi, lorsque l'on presse sur le bouton poussoir 28, la tige 32 se déplace par rapport au verrou 28 dans le sens de la flèche F tout en comprimant le ressort 30 jusqu'à ce que la goupille 52 vienne en butée contre les parois d'extrémité des ouvertures oblongues 54. Le déplacement de la tige 32 par rapport au verrou 28 sous l'action du bouton-poussoir permet à la face 68 de venir en contact avec le bord 70 de l'épaulement 58 et de glisser sur ce bord vers l'intérieur du deuxième logement 56 par rotation du verrou dans le sens de la flèche R. Simultanément, la face de retenue 62 glisse le long du bord de l'ouverture 14 jusqu'à ce que la came 64 rencontre la portion inclinée de la paroi 66 ce qui force la partie d'accrochage 40 à pénétrer entièrement dans le deuxième logement 56. Ainsi, la partie d'accrochage 40 s'escamote complètement à l'intérieur du tube 22 et permet un dégagement latéral de la barrette 6 des passages 12 et 14 pour libérer le bracelet 4.So when you press the push button 28, the rod 32 moves relative to the latch 28 in the direction of arrow F while compressing spring 30 until the pin 52 comes into abutment against the end walls of the oblong openings 54. The displacement of the rod 32 relative to the lock 28 under the action of the push button allows the face 68 to come in contact with the edge 70 of the shoulder 58 and of slide on this edge towards the inside of the second housing 56 by rotation of the lock in the direction of arrow R. Simultaneously, the retaining face 62 slides along the edge of opening 14 until cam 64 meets the inclined portion of the wall 66 which forces the portion hook 40 to fully penetrate the second housing 56. Thus, the hooking part 40 retracts completely inside the tube 22 and allows a lateral release of bar 6 from passages 12 and 14 to release the bracelet 4.

Lorsque l'on cesse d'agir sur les moyens d'actionnement 38, le ressort 30 rappelle la tige de commande 32 dans le sens de la flèche B, provoquant le glissement du bord 70 de l'épaulement 58 sur la face 68 jusqu'à ce que la partie d'accrochage 40 pénètre dans l'ouverture 46 pour que la face de retenue 62 puisse venir s'appuyer contre la paroi intérieure 48 de la corne 10.When we stop acting on the means actuation 38, the spring 30 recalls the rod command 32 in the direction of arrow B, causing the sliding of the edge 70 of the shoulder 58 on the face 68 until the hooking part 40 enters the opening 46 so that the retaining face 62 can come to rest against the interior wall 48 of the horn 10.
