Definitions

  • the present invention relates to a timepiece comprising a latch and push-button control device which falls within the first aspect of the invention.
  • auxiliary mechanisms which do not operate permanently, but are intended to be started by the wearer of the watch.
  • 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 some. also which have their own mainspring.
  • Watches which 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 charge 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, bolts, rods, correctors and other levers) which are generally arranged along the circumference of the watch case, at mid-height of its caseband. Most of the actuators are designed to move axially inside radial holes which pass through the middle part.
  • locks are an exception to this rule, since they are usually movable along the circumference of the caseband of the watch. Since they thus move on the surface of the watch case, the locks need more space than the other controls. 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 even more difficult, which reconciles aesthetics and ergonomics.
  • the total external length of the control device measured parallel to the slide, is equal to the length of the outer part of the lock.
  • the passage part of the pusher is embedded in the wall of the box, while the head part is arranged to move along the path. 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 designed to be able to cooperate with the feed-through part when the latch is in the rest position.
  • the outer part of the lock has 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 lock, so as to protrude above the opening that the latter has.
  • 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 pusher can be actuated by exerting pressure on the cover so as to cause it to pivot and bring it to the fully folded position.
  • the outer part of the lock can move along the slide in the manner of a carriage equipped with runners.
  • the two protruding 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 moves away from the lateral groove in the direction of the bottom of the slideway.
  • the two protruding parts of the second pair are each located at the location of a branch when the lock is in the rest position.
  • the timepiece comprises an auxiliary mechanism comprising a dedicated mainspring, and the latch of the latch and pusher control device is arranged to charge the dedicated mainspring.
  • the auxiliary mechanism is arranged so that when the lock of the control device is actuated to arm the mainspring, the starting of the mechanism is not at the same time caused. auxiliary. To start the latter, the pushbutton of the control device must still be actuated after having charged the mainspring.
  • the timepiece is a wristwatch and the latch and push-button control device is arranged on the left side of the watch case.
  • FIGS. 1A and 1B are schematic sectional views which illustrate the lock and push 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 being generally referenced 23.
  • the figures 1A and 1B respectively illustrate the lock of the control device in the rest position and in the end-of-travel position.
  • This lock comprises an exterior part 11 comprising a bolt 13 arranged to slide on the exterior surface of the middle part 1 along a slide 15. It can be seen that the exposed (exterior) face of the bolt 13 has a transverse edge 14 and that its inner face (facing the caseband) bears a finger (referenced 17 in the figure 4 ) which is directed radially towards the interior of the timepiece.
  • a short gorge (referenced 16 in the figure 4 ) is also 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 travel of the bolt 13, so as to allow the finger 17 to accompany the movements of the latter by traversing the gorge 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 hole 24 which is inserted into the thickness of the middle part 1.
  • the rod of 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 hole 24 in the direction of the groove 16.
  • a helical spring 29 tends to hold the rod actuation 21 against the finger 17.
  • the blind hole 24 opens onto the inside 23 of the watch case to allow a radial arm 33 to pass through a flange 22 of the actuating rod 21, this radial arm 33 being arranged to cooperate with a tooth 36 of a rake 35 pivotally arranged 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 outside of the watch case, in addition to being in communication with the inside 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 inner part 19 of the lock illustrated in the drawings could be replaced by other forms of inner part of the latch known to those skilled in the art, including interior parts integrating with the outer part of the latch.
  • the rake 35 could also be replaced by another transmission member.
  • FIG 3 shows on the other hand that the bolt 13 has a bore 41 provided with a countersink 42, and that the head portion 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 comes to be 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.
  • the passage part 39 is of a construction quite similar 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 figure 3 shows a through tube 56 having the shape of a cylindrical chamber open at one end so as to open out to the outside of the middle part 1 at the level of the slide 15.
  • the other end of the through tube 56 is provided with a bottom which is pierced with a guide orifice concentric with the tube.
  • the movable part of the passage 39 is formed 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 actuator bar 60 is fixed by one end to the center of the underside of the plug 58 in the form of a cylindrical pellet, while the other end of the bar 60 is inserted into the guide hole, so as to protrude. caseband 1 inside 23 of the watch case.
  • a helical compression spring 63 is arranged inside the through 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 through tube 56.
  • the pusher of the control device of the present example operates only when the latch is in the rest position and that the head part 38 of the pusher is therefore positioned in the extension of the passage part 39.
  • the operation of the pusher is as follows. When a user presses on the head portion 38 of the pusher, he slides the cylindrical portion of the cap 48 and the tip 47 inside the pusher tube 44, so that the free end of the tip 47 protrudes 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 figure 5 is a sectional view which illustrates a watch equipped with a latch and push-button control device according to a second exemplary embodiment of the invention.
  • the sectional view of the figure 5 is made according to the median horizontal plane of the watch.
  • the latter can be of any model. It will therefore generally be a different model from that of the watch which appeared in the first example.
  • the watch shown in figure 5 is of the same model as that of the first example. So it is only the latch and push control device that 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 relation to the figures 1A to 4 are designated by the same reference numbers.
  • the inner part 19 of the lock looks like 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-of-travel position (not shown).
  • the articulation between the cover 148 and the base 113 is effected 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 positioned. moves towards its end position.
  • the lateral grooves 219 each comprise branches giving rise to three secondary grooves 217b, 217c and 217d which move away from the lateral groove towards 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 protrusions of the second, third and fourth pairs can be lowered along the secondary grooves when the latch is in the rest position. The lowering of the protrusions allows the entire outer part of the lock to pivot about the straight line common to the two protrusions of the first pair.
  • 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.
