Definitions
- Complicated watches which comprise one or more auxiliary mechanisms which do not operate permanently, but are intended to be started by the wearer of the watch.
- auxiliary mechanisms can be designed to be driven from the barrel of the watch movement, but there are also some which have their own mainspring.
- Watches that contain an auxiliary mechanism of the latter type are most often equipped with a winding lock. The function of this lock is to allow the wearer of a watch to wind the mainspring of the auxiliary mechanism and often also to start the latter at the same time.
- a complicated watch can include a large number of control members (buttons, pushers, locks, rods, correctors and other levers) which are generally arranged along the circumference of the watch case, halfway up its middle. Most control members are designed to move axially inside radial bores which pass through the caseband. We know, however, that locks are an exception to this rule, since they are usually movable along the circumference of the middle part of the watch. Due to the fact that they thus move over the surface of the watch case, the locks require more space than the other control elements. It will therefore be understood that the presence of a lock can make the task of finding an arrangement of the control members of a complicated watch, which reconciles aesthetics and ergonomics, even more difficult.
- An object of the present invention is to remedy the drawbacks of the prior art which have just been explained.
- the present invention achieves this and other objects by providing, in accordance with its first aspect, a latch-and-push control device which is in accordance with appended claim 1. It also achieves the same aims by providing, in accordance with its second aspect, a timepiece which comprises a control device with lock and pusher, and which is in accordance with the appended claim 10.
- the total outer length of the control device measured parallel to the slide, is equal to the length of the outer part of the lock. Thanks to this characteristic, it is possible to arrange a bolt and a pusher in the space which is normally necessary to accommodate only a bolt. This results in an appreciable space saving.
- the traversing part of the pusher is embedded in the wall of the box, while the head part is arranged to move along the slide integrally with the outer part of the lock, while also being movable in a direction substantially transverse to the slide.
- the head part of the pusher is arranged to be able to cooperate with the crossing part when the lock is in the rest position.
- the outer part of the lock comprises an opening arranged so as to be in the extension of the through hole when the lock is in the rest position.
- the head part of the pusher is mounted on the outer part of the latch, so as to project above the opening that the latter comprises.
- the head part of the pusher is in the form of a push button which, although mounted on the outer part of the lock, may itself have a traditional shape.
- the outer part of the lock comprises a base arranged to be guided by the slide, a cover which is pivotally mounted on the base so as to be movable between a half-open angular position and a fully folded angular position, and a spring arranged to return the hood to its half-open angular position.
- the cover carries a rod which moves in the direction substantially transverse to the slide when the cover pivots by relative to the base, and the latter further has an opening arranged to provide a passage for the rod through the base.
- the pusher can be actuated by exerting pressure on the cover so as to cause it to pivot and to bring it into the fully folded position.
- the slide along which the outer part of the lock is arranged to slide is delimited on either side by two parallel raised edges which each have a lateral groove which is extends parallel to the slide, the two lateral grooves being arranged opposite one another.
- the outer part of the lock comprises at least a first and a second pair of projecting parts, the two projecting parts of each pair being respectively intended to be inserted into the two lateral grooves so as to cooperate with the latter to guide the lock .
- the outer part of the lock can move along the slideway like a carriage equipped with pads.
- the two projecting parts of the first pair are arranged on the same straight line perpendicular to a plane of symmetry between the two lateral grooves.
- the lateral grooves each comprise at least one branch giving rise to a secondary groove which deviates from the lateral groove in the direction of the bottom of the slide.
- the two projecting parts of the second pair are each located at the location of a branch when the lock is in the rest position.
- the two projecting parts of the second pair can be lowered along the grooves secondary when the lock is in the rest position.
- the lowering of the protrusions of the second pair allows the entire outer part of the lock to pivot around the line common to the two protrusions of the first pair.
- An advantage of this last embodiment is that it makes it possible to further reduce the number of parts in comparison with the second variant.
- the timepiece comprises an auxiliary mechanism comprising a dedicated mainspring, and the latch of the latch and push-button control device is arranged to arm the dedicated mainspring.
- the auxiliary mechanism is arranged so that when the lock of the control device is actuated to arm the mainspring, the mechanism does not start up at the same time. auxiliary. To start the latter, one must still operate the plunger of the control device after having charged the mainspring.
- the timepiece is a wristwatch and the lock and push-button control device is arranged on the left side of the watch case.
- FIG. 1A and 1B are schematic cross-sectional views illustrating the lock and push-button control device of the present example, as well as its integration into a watch case. It will be understood that these figures show only the control device and the middle part (referenced 1), the rest of the case not being visible, and the interior of the latter generally being referenced 23.
- the figure 1A and 1B respectively illustrate the latch of the control device in the rest position and in the end-of-travel position.
- This lock comprises an outer part 11 comprising a bolt 13 arranged to slide on the outer surface of the middle part 1 along a slideway 15. It can be seen that the exposed (outer) face of the bolt 13 has a transverse edge 14 and that its inner face (turned towards the middle) bears a finger (referenced 17 in the figure 4 ) which is directed radially towards the inside of the timepiece.
- a short groove (referenced 16 in the figure 4 ) is still formed in the middle part 1 to receive the distal end of the finger 17. The length of the groove is at least equal to the length of the stroke of the bolt 13, so as to allow the finger 17 to accompany the movements of the latter by traversing the throat 16.
- the lock further comprises an inner part 19 which is kinematically connected to the outer part 11, while being housed inside 23 of the watch case.
- the inner part 19 of the lock comprises, in a manner known per se, an actuating rod 21 engaged in a blind bore 24 which is inserted into the thickness of the middle part 1.
- the actuation 21 is guided by a guide ring 26 which is provided with an annular seal 27 and which is arranged at the mouth of the blind bore 24 in the direction of the groove 16.
- a helical spring 29 tends to hold the rod 21 against the finger 17.
- the blind hole 24 opens onto the inside 23 of the watch case to allow a radial arm 33 secured to a flange 22 of the actuating rod 21 to pass, this radial arm 33 being arranged to cooperate with a tooth 36 of a rake 35 arranged to pivot inside the box.
- the blind hole 24 is arranged in the extension of the groove 16 and that it sinks into the thickness of the middle part 1 in a direction approximately tangent to the latter.
- the blind hole 24 opens into the groove 16, so that it is in communication with the exterior of the watch case, in addition to being in communication with the interior 23 of the watch case.
- the annular seal 27 surrounds the actuating rod 21 so as to isolate the interior 23 of the watch case from the outside, while allowing the actuating rod 21 to slide longitudinally.
- the operation of the lock is as follows, a user can slide the bolt 13 along the slide 15 from the rest position ( Figure 1A ) to the end position ( Figure 1B ) by pushing the edge 14 of the bolt clockwise using his thumb.
- the bolt 13 When the bolt 13 is moved in this way by the user, it carries with it the finger 17 which runs through the groove 16 pushing the end of the actuating rod 21 in front of it. The latter is thus pushed back towards the bottom of the hole blind 24 against the helical spring 29 and actuates the rake 35 via the radial arm 33.
- the interior part 19 of the lock illustrated in the drawings could be replaced by other forms of interior part of the lock known to those skilled in the art, including interior parts integral with the exterior part of the lock.
- the rake 35 could also be replaced by another transmission member.
- the picture 3 is an enlargement of part of the Figure 1A showing more particularly the pusher of the latch and pusher control device of the present example.
- the pusher comprises a head part 38 which is mounted on the bolt 13 and a crossing part (also called “crossing") 39 which is embedded in the middle part 1.
- the bolt 13 is engaged in the slideway 15, the latter being formed in the surface of the middle part 1.
- the picture 3 it can be seen first of all that the slide has two grooves 31 arranged opposite one another, and that the side faces of the bolt 13 have two projecting edges which are respectively engaged in the two grooves.
- the picture 3 shows on the other hand that the bolt 13 has a bore 41 provided with a counterbore 42, and that the head part 38 of the pusher comprises a pusher tube 44 which is provided with a collar 45.
- the pusher tube 44 is engaged in the bore 41 so that the collar 45 is housed in the counterbore 42.
- a push button comprising a tip 47 and a cap 48 is inserted into the tube 44 so as to be guided axially to move between a position of rest and an active position.
- the cap 48 protrudes above the tube 44.
- annular hollow 50 which surrounds a central cylindrical portion in which the threaded end of the tip 47 is screwed.
- the cap 48 is recalled in the rest position by a helical spring 51 which surrounds the central cylindrical portion of the cap.
- the traversing part 39 is of construction completely analogous to that of certain correctors (known as such) which are generally embedded in the middle part of a complication watch and which are operated with a tool meant for that purpose.
- the picture 3 shows a crossing tube 56 having the shape of a cylindrical chamber open at one end so as to emerge outside the middle part 1 at the level of the slideway 15.
- the other end of the crossing tube 56 is provided with a bottom which is pierced with a concentric guide orifice with the tube.
- the movable part of the crossing 39 is constituted by the assembly of a plug 58 in the form of a cylindrical pellet and an actuating bar 60.
- the plug 58 is inserted into the tube 56 with the interposition of an O-ring 61 , so as to allow the plug to slide axially.
- the actuating bar 60 is fixed by one end to the center of the lower face of the cap 58 in the form of a cylindrical pellet, while the other end of the bar 60 is inserted into the guide orifice, so as to protrude from the caseband 1 inside 23 of the watch case.
- a helical compression spring 63 is arranged inside the crossing tube 56 so as to surround the actuating bar 60. The spring 63 bears by one of its ends against the plug 58 and by its other end against the bottom of the crossing tube 56.
- the pusher of the control device of this example operates only when the lock is in the rest position and that the head part 38 of the pusher is therefore positioned in the extension of the crossing part 39
- the operation of the pusher is as follows.
- a user presses on the head part 38 of the pusher he slides the cylindrical part of the cap 48 and the tip 47 inside the pusher tube 44, so that the free end of the tip 47 projects from the inner face of the bolt 13.
- the shape of the tip 47 is complementary to that of the upper face of the plug 58 in the form of a cylindrical pellet, the tip 47 can cooperate with the plug 58 of so as to push it against the coil spring 63 towards the inside of the watch case.
- the actuating bar 60 being fixed to the stopper 58, its free end moves axially inside the watch case.
- a problem with most known pushers is that the force that the user exerts with his finger or his thumb on the head part 38 of the pusher almost always has a component which acts transversely to the axis of the pusher. In other words, the pressure exerted by the user on the pusher is almost always accompanied by parasitic forces.
- the crossing part 39 is actuated indirectly, by means of a head part 38 distinct from the crossing part, makes it possible to remedy this problem by preventing the parasitic forces generated by the user are communicated to the traversal party. This results in an improvement in the sealing of the crossing part 39.
- the figure 5 is a sectional view illustrating a watch equipped with a lock and pusher control device according to a second exemplary embodiment of the invention.
- the sectional view of the figure 5 is made along the median horizontal plane of the watch.
- the latter can be of any model. It will therefore generally be a different model than the watch that appeared in the first example.
- the watch illustrated in the figure 5 is of the same model as that of the first example. There is therefore only the latch and push-button control device which is different. This is the reason why the elements of the figure 5 which are identical or similar to elements which have already been described in connection with the figures 1A to 4 are designated by the same reference numbers.
- the inner part 19 of the lock resembles the inner part of the lock of the first example.
- the outer part 111 of the lock comprises a base 113 and a cover 148 pivotally mounted on the base. The latter is arranged to slide along the slide 15 between a rest position ( figure 5 ) and an end position (not shown).
- the articulation between the cover 148 and the base 113 is achieved by means of a pin 121 which is arranged close to the end of the base which is at the front when the lock is moves towards its end position.
- the cover 148 at least partially covers the base 113 and it is arranged to be able to pivot relative to the latter within a small angular interval delimited on either side by a half-open position (illustrated in the figure) and a fully folded position (not shown).
- the outer part 111 further comprises a return spring (not shown) which is arranged to return the cowl 148 to its half-open position.
- the figure 5 further shows that the distal end of the cover forms a prominence 114 in the form of a ridge on the lock. It will be understood that a user can actuate the lock by pushing the edge 114 clockwise.
- the cover 148 also performs the function of the pusher head.
- the base 113 comprises an opening (not shown) which is arranged so as to allow the passage of the rod 147 so that the latter can come to cooperate with the stopper 58 when the lock is in the rest position and a user presses on the cover 148 to bring it into the fully folded position.
- the figure 6 , 7 and 8 are partial views of a latch and push-button control device which is in accordance with a third particular embodiment of the invention.
- the lock of the control device which is the subject of this third example comprises an outer part and an inner part. However, the inner part is not shown in the figures.
- the outer part 211 of the lock comprises a base 213 and a cover 248 which is fixed rigidly to the base so as to cover it.
- the part exterior of the lock is arranged to slide along the slide 15 between a rest position ( figure 6 and 7 ) and an end position (not shown). It is also provided with a rod 247 which is in the axis of the traversing part 239 of the pusher when the lock is in the rest position.
- Two lateral grooves (referenced 219 in the figure 7 ) parallel to the slide 15 are arranged in the raised edges of the slide opposite one another.
- the outer part of the lock has a first 221a, a second 221b, a third 221c and a fourth pair 221d of projections.
- the two projecting parts forming each pair are arranged on either side of the lock, so as to cooperate with the two lateral grooves 219 to guide the lock.
- the two projecting parts 221a of the first pair are aligned on a straight line (vertical in the figure 7 ) perpendicular to the longitudinal plane of symmetry of the slide 15.
- the projecting parts of each of the other three pairs 221b, 221c and 221d can also be aligned on straight lines perpendicular to the aforementioned plane of symmetry.
- the protrusions located on the same side of the outer part 211 of the lock are arranged along a rounded line corresponding to the junction between the base 213 and the cover 248.
- the lateral grooves 219 each comprise branches giving rise to three secondary grooves 217b, 217c and 217d which deviate from the lateral groove in the direction of the bottom of the slide 15, and the projecting parts of the second 221b, of the third 221c and of the fourth pair 221d are each located at a branch when the lock is in the rest position. Thanks to these characteristics, the projecting parts of the second, third and fourth pairs can be lowered along the secondary grooves when the lock is in the rest position. The lowering of the projecting parts allows the entire outer part of the lock to pivot around the line common to the two projecting parts of the first pair.
- the projecting parts 221a, 221b, 221c and 221d consist of balls which are each housed in a hole provided on one side of the upper part of the lock.
- the holes in which the balls are housed are located at the junction between the base and the cover. These holes are shallow, so the balls protrude from the holes.
- the figure 9 shows an example of a sequence of use of the lock and push-button control device according to the invention in the case of a chronograph.
- the latch and the pusher are in the rest state.
- the bolt is actuated to wind the mainspring of the chronograph mechanism.
- the lock, released by the user is returned to its rest position by a return spring.
- the user actuates the pusher while the lock is in its rest position, in order to start timing.
- the chronograph mechanism is running and the pusher, released by the user, is returned to its rest position by a return spring.
- the pusher is pressed to stop timing.
- the pusher released by the user, is returned to its rest position by its return spring and the chronograph mechanism is stopped.
- the pusher is pressed again to reset the chronograph.
- the latch and push-button control device By arranging the latch and push-button control device according to the invention on the left side of the watch case, as shown in figure 9 , the user is allowed to successively arm the chronograph, the trigger, stop and reset it only with the right thumb. The resulting gain in terms of ergonomics is significant.
- the lock could be used to arm a striking mechanism, typically a minute repeater, and the pusher to trigger the striking. Contrary to the known minute repeaters, the ringtone would therefore not be triggered automatically after arming but at the time chosen by the user.
- Countdowns are another example of application of the invention, with winding by the bolt and triggering by the pusher.
- the head part of the pusher is not mounted on the outer part of the latch, but that it can alternatively be mounted on the outer face of the wall of the watch case in the extension of the crossing part.
- the outer part of the lock and the head part of the pusher are arranged so as to be superposed or nested when the lock is in the rest position.

On connaît des montres compliquées qui comportent un ou plusieurs mécanismes auxiliaires qui ne fonctionnent pas en permanence, mais sont prévus pour être mis en marche par le porteur de la montre. A titre d'exemple, on peut citer notamment les mécanismes de chronographe et les mécanismes de sonnerie à répétition minute. Ces mécanismes auxiliaires peuvent être conçus pour être entraînés à partir du barillet du mouvement de la montre, mais il en existe également qui possèdent leur propre ressort-moteur. Les montres qui contiennent un mécanisme auxiliaire de ce dernier type sont le plus souvent équipées d'un verrou d'armage. La fonction de ce verrou est de permettre au porteur d'une montre d'armer le ressort-moteur du mécanisme auxiliaire et souvent également de faire démarrer du même coup ce dernier.Complicated watches are known which comprise one or more auxiliary mechanisms which do not operate permanently, but are intended to be started by the wearer of the watch. By way of example, mention may be made in particular of chronograph mechanisms and minute repeater striking mechanisms. These auxiliary mechanisms can be designed to be driven from the barrel of the watch movement, but there are also some which have their own mainspring. Watches that contain an auxiliary mechanism of the latter type are most often equipped with a winding lock. The function of this lock is to allow the wearer of a watch to wind the mainspring of the auxiliary mechanism and often also to start the latter at the same time.
Une montre compliquée peut comprendre un nombre important d'organes de commande (boutons, poussoirs, verrous, tiges, correcteurs et autres levier) qui sont généralement agencés le long de la circonférence de la boîte de montre, à mi-hauteur de sa carrure. La plupart des organes de commande sont conçus pour se déplacer axialement à l'intérieur de perçages radiaux qui traversent la carrure. On sait toutefois que les verrous font exception à cette règle, puisqu'ils sont habituellement mobiles le long de la circonférence de la carrure de la montre. Du fait qu'ils se déplacent ainsi sur la surface de la boîte de montre, les verrous ont besoin de plus de place que les autres organes de commande. On comprendra donc que la présence d'un verrou, peut rendre encore plus ardue la tâche de trouver un agencement des organes de commande d'une montre compliquée, qui concilie esthétique et ergonomie.A complicated watch can include a large number of control members (buttons, pushers, locks, rods, correctors and other levers) which are generally arranged along the circumference of the watch case, halfway up its middle. Most control members are designed to move axially inside radial bores which pass through the caseband. We know, however, that locks are an exception to this rule, since they are usually movable along the circumference of the middle part of the watch. Due to the fact that they thus move over the surface of the watch case, the locks require more space than the other control elements. It will therefore be understood that the presence of a lock can make the task of finding an arrangement of the control members of a complicated watch, which reconciles aesthetics and ergonomics, even more difficult.
Un but de la présente invention est de remédier aux inconvénients de l'art antérieur qui viennent d'être expliqués. La présente invention atteint ce but ainsi que d'autres en fournissant, conformément à son premier aspect, un dispositif de commande à verrou et poussoir qui est conforme à la revendication 1 annexée. Elle atteint également les mêmes buts en fournissant, conformément à son deuxième aspect, une pièce d'horlogerie qui comporte un dispositif de commande à verrou et poussoir, et qui est conforme à la revendication 10 annexée.An object of the present invention is to remedy the drawbacks of the prior art which have just been explained. The present invention achieves this and other objects by providing, in accordance with its first aspect, a latch-and-push control device which is in accordance with appended
Conformément à l'invention, lorsque le verrou est en position de repos la longueur extérieure totale du dispositif de commande, mesurée parallèlement à la glissière, est égale à la longueur de la partie extérieure du verrou. Grâce à cette caractéristique, il est possible d'agencer un verrou et un poussoir dans l'espace qui est normalement nécessaire pour accueillir uniquement un verrou. Il en résulte un gain de place appréciable.According to the invention, when the lock is in the rest position, the total outer length of the control device, measured parallel to the slide, is equal to the length of the outer part of the lock. Thanks to this characteristic, it is possible to arrange a bolt and a pusher in the space which is normally necessary to accommodate only a bolt. This results in an appreciable space saving.
Conformément à un mode de réalisation particulier dont les caractéristiques distinctives relèvent du premier aspect de l'invention, la partie de traversée du poussoir est noyée dans la paroi de la boîte, alors que la partie de tête est agencée pour se déplacer le long de la glissière solidairement de la partie extérieure du verrou, tout en étant également mobile dans une direction sensiblement transversale à la glissière. De plus, la partie de tête du poussoir est agencée pour pouvoir coopérer avec la partie de traversée lorsque le verrou est en position de repos.According to a particular embodiment, the distinctive characteristics of which come under the first aspect of the invention, the traversing part of the pusher is embedded in the wall of the box, while the head part is arranged to move along the slide integrally with the outer part of the lock, while also being movable in a direction substantially transverse to the slide. In addition, the head part of the pusher is arranged to be able to cooperate with the crossing part when the lock is in the rest position.
Conformément à une première variante du mode de réalisation ci-dessus, la partie extérieure du verrou comporte une ouverture agencée de façon à se trouver dans le prolongement du perçage traversant lorsque le verrou est en position de repos. De plus, la partie de tête du poussoir est montée sur la partie extérieure du verrou, de manière à faire saillie au-dessus de l'ouverture que comporte cette dernière.According to a first variant of the embodiment above, the outer part of the lock comprises an opening arranged so as to be in the extension of the through hole when the lock is in the rest position. In addition, the head part of the pusher is mounted on the outer part of the latch, so as to project above the opening that the latter comprises.
On comprendra que, conformément à cette première variante, la partie de tête du poussoir se présente sous la forme d'un bouton de poussoir qui, bien que monté sur la partie extérieure du verrou, peut présenter lui-même une forme traditionnelle.It will be understood that, in accordance with this first variant, the head part of the pusher is in the form of a push button which, although mounted on the outer part of the lock, may itself have a traditional shape.
Conformément à une deuxième variante particulière du mode de réalisation ci-dessus, la partie extérieure du verrou comprend une base agencée pour être guidée par la glissière, un capot qui est monté pivotant sur la base de manière à être mobile entre une position angulaire entrebâillée et une position angulaire complètement rabattue, et un ressort agencé pour rappeler le capot vers sa position angulaire entrebâillée. Le capot porte une tige qui se déplace dans la direction sensiblement transversale à la glissière lorsque le capot pivote par rapport à la base, et cette dernière présente en outre une ouverture agencée pour offrir un passage à la tige à travers la base.According to a second particular variant of the embodiment above, the outer part of the lock comprises a base arranged to be guided by the slide, a cover which is pivotally mounted on the base so as to be movable between a half-open angular position and a fully folded angular position, and a spring arranged to return the hood to its half-open angular position. The cover carries a rod which moves in the direction substantially transverse to the slide when the cover pivots by relative to the base, and the latter further has an opening arranged to provide a passage for the rod through the base.
On comprendra que, conformément à cette deuxième variante, on peut actionner le poussoir en exerçant une pression sur le capot de manière à le faire pivoter et à l'amener en position complètement rabattue. Un avantage de cette deuxième variante est qu'elle permet de limiter le nombre de pièces tout en offrant un choix plus étendu en matière de forme et d'agencement.It will be understood that, in accordance with this second variant, the pusher can be actuated by exerting pressure on the cover so as to cause it to pivot and to bring it into the fully folded position. An advantage of this second variant is that it makes it possible to limit the number of parts while offering a wider choice in terms of shape and layout.
Conformément à une troisième variante particulière du mode de réalisation ci-dessus, la glissière le long de laquelle la partie extérieure du verrou est agencée pour coulisser est délimitée de part et d'autre par deux bords surélevés parallèles qui présentent chacun une rainure latérale qui s'étend parallèlement à la glissière, les deux rainures latérales étant agencées en regard l'une de l'autre. De plus, la partie extérieure du verrou comporte au moins une première et une deuxième paire de parties saillantes, les deux parties saillantes de chaque paire étant respectivement destinées à être insérées dans les deux rainures latérales de manière à coopérer avec ces dernières pour guider le verrou.According to a third particular variant of the embodiment above, the slide along which the outer part of the lock is arranged to slide is delimited on either side by two parallel raised edges which each have a lateral groove which is extends parallel to the slide, the two lateral grooves being arranged opposite one another. In addition, the outer part of the lock comprises at least a first and a second pair of projecting parts, the two projecting parts of each pair being respectively intended to be inserted into the two lateral grooves so as to cooperate with the latter to guide the lock .
On comprendra que conformément à cette troisième variante, la partie extérieure du verrou peut se déplacer le long de la glissière à la manière d'un chariot équipé de patins.It will be understood that in accordance with this third variant, the outer part of the lock can move along the slideway like a carriage equipped with pads.
Conformément à un mode de réalisation avantageux de la troisième variante ci-dessus, les deux parties saillantes de la première paire sont agencées sur une même droite perpendiculaire à un plan de symétrie entre les deux rainures latérales. De plus, les rainures latérales comportent chacune au moins un embranchement donnant naissance à une rainure secondaire qui s'écarte de la rainure latérale en direction du fond de la glissière. Enfin, les deux parties saillantes de la deuxième paire sont situées chacune à l'endroit d'un embranchement lorsque le verrou se trouve en position de repos.In accordance with an advantageous embodiment of the third variant above, the two projecting parts of the first pair are arranged on the same straight line perpendicular to a plane of symmetry between the two lateral grooves. In addition, the lateral grooves each comprise at least one branch giving rise to a secondary groove which deviates from the lateral groove in the direction of the bottom of the slide. Finally, the two projecting parts of the second pair are each located at the location of a branch when the lock is in the rest position.
On comprendra que, grâce à ces caractéristiques, les deux parties saillantes de la deuxième paire peuvent s'abaisser le long des rainures secondaires lorsque le verrou est en position de repos. L'abaissement des parties saillantes de la deuxième paire permet à la partie extérieure du verrou tout entière de pivoter autour de la droite commune aux deux parties saillantes de la première paire. Conformément à ce mode de réalisation avantageux, il est possible d'actionner le poussoir en exerçant une pression sur la partie extérieure du verrou de manière à la rabattre contre le fond de la glissière en la faisant pivoter. Un avantage de ce dernier mode de réalisation est qu'il permet de réduire encore le nombre de pièce en comparaison avec la deuxième variante.It will be understood that, thanks to these characteristics, the two projecting parts of the second pair can be lowered along the grooves secondary when the lock is in the rest position. The lowering of the protrusions of the second pair allows the entire outer part of the lock to pivot around the line common to the two protrusions of the first pair. In accordance with this advantageous embodiment, it is possible to actuate the pusher by exerting pressure on the outer part of the lock so as to fold it back against the bottom of the slide by causing it to pivot. An advantage of this last embodiment is that it makes it possible to further reduce the number of parts in comparison with the second variant.
Conformément à un mode de réalisation particulier dont les caractéristiques distinctives relèvent du deuxième aspect de l'invention, la pièce d'horlogerie comporte un mécanisme auxiliaire comprenant un ressort-moteur dédié, et le verrou du dispositif de commande à verrou et poussoir est agencé pour armer le ressort-moteur dédié.According to a particular embodiment, the distinctive characteristics of which come under the second aspect of the invention, the timepiece comprises an auxiliary mechanism comprising a dedicated mainspring, and the latch of the latch and push-button control device is arranged to arm the dedicated mainspring.
Selon une variante avantageuse du mode de réalisation ci-dessus, le mécanisme auxiliaire est agencé de sorte que lorsqu'on actionne le verrou du dispositif de commande pour armer le ressort-moteur, on ne provoque pas, du même coup, le démarrage du mécanisme auxiliaire. Pour faire démarrer ce dernier, on doit encore actionner le poussoir du dispositif de commande après avoir armé le ressort-moteur. Cette variante présente l'avantage de permettre de faire démarrer le mécanisme auxiliaire au moment souhaité par l'utilisateur après l'armage. Selon une variante préférée, la pièce d'horlogerie est une montre-bracelet et le dispositif de commande à verrou et poussoir est agencé sur le côté gauche de la boîte de montre. Un avantage de cette variante préférée est qu'elle permet de manipuler le dispositif de commande avec le pouce uniquement ; main droite immobile.According to an advantageous variant of the above embodiment, the auxiliary mechanism is arranged so that when the lock of the control device is actuated to arm the mainspring, the mechanism does not start up at the same time. auxiliary. To start the latter, one must still operate the plunger of the control device after having charged the mainspring. This variant has the advantage of making it possible to start the auxiliary mechanism at the time desired by the user after winding. According to a preferred variant, the timepiece is a wristwatch and the lock and push-button control device is arranged on the left side of the watch case. An advantage of this preferred variant is that it allows manipulation of the control device with the thumb only; motionless right hand.

Conformément à l'invention, le verrou comporte encore une partie intérieure 19 qui est reliée cinématiquement à la partie extérieure 11, tout en étant logée à l'intérieur 23 de la boîte de montre. Comme le montrent les
On peut voir que le perçage borgne 24 est agencé dans le prolongement de la gorge 16 et qu'il s'enfonce dans l'épaisseur de la carrure 1 selon une direction approximativement tangente à cette dernière. Le perçage borgne 24 débouche dans la gorge 16, de sorte qu'il est en communication avec l'extérieur de la boîte de montre, en plus d'être en communication avec l'intérieur 23 de la boîte de montre. Le joint annulaire 27 entoure la tige d'actionnement 21 de manière à isoler l'intérieur 23 de la boîte de montre de l'extérieur, tout en permettant à la tige d'actionnement 21 de coulisser longitudinalement.It can be seen that the
Le fonctionnement du verrou est le suivant, un utilisateur peut faire coulisser la targette 13 le long de la glissière 15 de la position de repos (
La partie intérieure 19 du verrou illustrée sur les dessins pourrait être remplacée par d'autres formes de partie intérieure de verrou connues de l'homme du métier, y compris des parties intérieures monobloc avec la partie extérieure du verrou. Le râteau 35 pourrait aussi être remplacé par un autre organe de transmission.The

L'homme du métier comprendra sans peine que le poussoir du dispositif de commande du présent exemple fonctionne uniquement lorsque le verrou est en position de repos et que la partie de tête 38 du poussoir se trouve donc positionnée dans le prolongement de la partie de traversée 39. Le fonctionnement du poussoir est le suivant. Lorsqu'un utilisateur presse sur la partie de tête 38 du poussoir, il fait coulisser la partie cylindrique du capuchon 48 et l'embout 47 à l'intérieur du tube de poussoir 44, de sorte que l'extrémité libre de l'embout 47 fait saillie de la face intérieure de la targette 13. Comme la forme de l'embout 47 est complémentaire de celle de la face supérieure du bouchon 58 en forme de pastille cylindrique, l'embout 47 peut coopérer avec le bouchon 58 de manière à le repousser à l'encontre du ressort hélicoïdal 63 en direction de l'intérieur de la boîte de montre. La barre d'actionnement 60 étant fixée au bouchon 58, son extrémité libre se déplace axialement à l'intérieur de la boîte de montre. Un problème avec la plupart des poussoirs connus est que la force que l'utilisateur exerce avec son doigt ou son pouce sur la partie de tête 38 du poussoir possède presque toujours une composante qui agit transversalement à l'axe du poussoir. Autrement dit, la pression exercée par l'utilisateur sur le poussoir s'accompagne presque toujours d'efforts parasites. Le fait que, dans le présent exemple, la partie de traversée 39 est actionnée indirectement, par l'intermédiaire d'une partie de tête 38 distincte de la partie de traversée, permet de remédier à ce problème en évitant que les efforts parasites engendrés par l'utilisateur ne soient communiqués à la partie de traversée. Il en résulte une amélioration de l'étanchéité de la partie de traversée 39.Those skilled in the art will easily understand that the pusher of the control device of this example operates only when the lock is in the rest position and that the

La partie extérieure du verrou présente une première 221a, une deuxième 221b, une troisième 221c et une quatrième paire 221d de parties saillantes. Les deux parties saillantes formant chaque paire sont arrangées de part et d'autre du verrou, de manière à coopérer avec les deux rainures latérales 219 pour guider le verrou. De plus, les deux parties saillantes 221a de la première paire sont alignées sur une droite (verticale dans la
Les rainures latérales 219 comportent chacune des embranchements donnant naissance à trois rainures secondaires 217b, 217c et 217d qui s'écartent de la rainure latérale en direction du fond de la glissière 15, et les parties saillantes de la deuxième 221b, de la troisième 221c et de la quatrième paire 221d sont situées chacune à un embranchement lorsque le verrou se trouve en position de repos. Grâce à ces caractéristiques, les parties saillantes des deuxième, troisième et quatrième paires peuvent s'abaisser le long des rainures secondaires lorsque le verrou est en position de repos. L'abaissement des parties saillantes permet à la partie extérieure du verrou tout entière de pivoter autour de la droite commune aux deux parties saillantes de la première paire. Il est ainsi possible d'actionner le poussoir en exerçant une pression sur la partie extérieure du verrou de manière à rabattre la tige 247 en direction du fond de la glissière 15 de façon que la tige 247 puisse venir coopérer avec la partie de traversée 239. On peut voir enfin que, dans l'exemple illustré, les parties saillantes 221a, 221b, 221c et 221d sont constituées par des billes qui sont logées chacune dans un trou aménagé sur un côté de la partie supérieure du verrou. Les trous dans lesquels les billes sont logées sont situés à la jonction entre la base et le capot. Ces trous sont peu profonds, de sorte que les billes dépassent des trous. Un avantage associé à l'utilisation de billes pour réaliser les paires de parties saillantes est que les frottements sont réduits, ce qui rend plus aisé de maitriser la force à exercer sur le verrou.The

D'autres applications qu'un chronographe sont envisageables. Par exemple, le verrou pourrait servir à armer un mécanisme de sonnerie, typiquement une répétition minutes, et le poussoir à déclencher la sonnerie. Contrairement aux répétitions minutes connues, la sonnerie ne se déclencherait donc pas automatiquement après l'armage mais au moment choisi par l'utilisateur. Les comptes à rebours sont un autre exemple d'application de l'invention, avec un armage par le verrou et un déclenchement par le poussoir.Applications other than a chronograph are possible. For example, the lock could be used to arm a striking mechanism, typically a minute repeater, and the pusher to trigger the striking. Contrary to the known minute repeaters, the ringtone would therefore not be triggered automatically after arming but at the time chosen by the user. Countdowns are another example of application of the invention, with winding by the bolt and triggering by the pusher.
On comprendra en outre que diverses modifications et/ou améliorations évidentes pour un homme du métier peuvent être apportées aux modes de réalisation qui font l'objet de la présente description sans sortir du cadre de la présente invention définie par les revendications annexées. On comprendra notamment que selon d'autres modes de réalisations, la partie de tête du poussoir n'est pas montée sur la partie extérieure du verrou, mais qu'elle peut alternativement être montée sur la face extérieure de la paroi de la boîte de montre dans le prolongement de la partie de traversée. Dans ce cas, la partie extérieure du verrou et la partie de tête du poussoir sont agencées de manière à être superposées ou emboîtées lorsque le verrou est en position de repos.It will also be understood that various modifications and/or improvements obvious to a person skilled in the art can be made to the embodiments which are the subject of the present description without departing from the scope of the present invention defined by the appended claims. It will be understood in particular that according to other embodiments, the head part of the pusher is not mounted on the outer part of the latch, but that it can alternatively be mounted on the outer face of the wall of the watch case in the extension of the crossing part. In this case, the outer part of the lock and the head part of the pusher are arranged so as to be superposed or nested when the lock is in the rest position.
