Definitions

  • the present invention relates to a timepiece comprising a mechanism for triggering a time function and the simultaneous arming of a mainspring. More particularly, the invention relates to such a timepiece whose mechanism allows the arming of a mainspring for activating a striking mechanism on the expiry of a predetermined time interval counted by a connected timer mechanism to the timepiece device of the timepiece.
  • timer mechanism there will be understood a device allowing the countdown of a predetermined time interval.
  • ring drum arming devices There are generally two types of ring drum arming devices depending on whether it is a clock watch or a minute repeater watch.
  • the barrel In clock-clocks, the barrel is conventionally armed by means of a stem winding and setting time of its own, the striking mechanism being triggered at a time determined by a trigger that allows then the barrel to provide energy to the hammer until the barrel of the ring is completely disarmed.
  • a disadvantage of this type of arrangement lies in the fact that the user can select a wake-up time and activate the alarm function without the barrel is necessarily armed so that it is possible that no ringing is triggered at any time. wakeup time selected if the barrel is completely disarmed.
  • the winding of the striking barrel is conventionally carried out by means of a slider which slides on the outer surface of the watch case and which is mechanically connected through an oblong opening to a slider with a rack arm cooperating with the ringer barrel.
  • the time indication is given by tones activated by the mechanism immediately after releasing the cursor.
  • a disadvantage of these slider mechanisms is that their construction is complex, cumbersome and generally to ensure a seal without an additional device for sealing and locking the cursor which complicates handling.
  • Such a mechanism is for example described in the patent CH 672 868 .
  • Another disadvantage of this type of mechanism lies in the fact that it does not allow energy to be stored in the ringer barrel for triggering the mechanism at any time.
  • the document CH-A-527 455 discloses a timepiece comprising a clockwork movement provided with a main barrel serving as energy source for a timekeeping device of the clockwork movement and an auxiliary barrel intended to supply mechanical energy to a watchdog device. alarm, and mechanical control means that can be actuated manually to engage the alarm device.
  • the main object of the present invention is to overcome the drawbacks of the abovementioned prior art by providing a timepiece comprising a mechanism for triggering a time function and the simultaneous arming of a mainspring, said mechanism having a simple and compact construction.
  • the invention also aims to provide a timepiece of the type described above, and in particular a wristwatch, in which the control means of the mechanism can be integrated into the watch case without affecting the seal of it.
  • the invention also aims to provide a timepiece of the type described above in which the control means comprise a control member of the conventional type.
  • Another object of the invention is to provide a timepiece of the type described above comprising a mechanism that makes it possible to arm the ringer barrel simultaneously with the triggering of an additional device, for example a timer, and in particular without disrupt the operation of the timepiece device of the timepiece.
  • the subject of the invention is a timepiece comprising a watch movement provided with a main barrel serving as a source of energy for a timekeeping device of the watch movement and an auxiliary barrel provided for supplying mechanical energy to an additional device, and mechanical control means that can be actuated manually to engage said additional device, characterized in that said control means are arranged to simultaneously switch on the additional device and arm the auxiliary cylinder.
  • the additional device comprises a ring associated with a timer mechanism connected to the timekeeping device of the watch movement, the ringing being triggered at the end of a time interval counted by the mechanism. timer.
  • the control means comprise a pusher.
  • a conventional pusher for arming the auxiliary barrel makes it easy to solve the sealing problems encountered with the slider-type auxiliary barrel control members of the prior art.
  • the pushers are readily available commercially, it also eliminates the costs associated with the development of a new controller. Thanks to this characteristic, the manufacture of this timepiece in the form of a waterproof wristwatch is simplified.
  • the figure 1 is a front view of a timepiece 10 of the wristwatch type classically comprising a watch movement containing the invention.
  • This piece 10 comprises an hour hand 30, a minute hand 31 and a small second hand 32 respectively driven by a timekeeping device of the watch movement.
  • the timekeeping device is conventionally powered by a main cylinder.
  • a calendar with a large counter 33 complements the indications provided by the timekeeping device.
  • the watch 10 shown also comprises a second hand 34 and a minute counter 11 providing a chronograph function.
  • the starting and stopping of the needle 34 and the counter 11 are carried out by means of a first pusher 35, while a second pusher 36 allows the reset of said indicators 34 and 11.
  • a crown 37 allows according to the axial positions to which it is brought, to arm a main barrel serving as a source of energy for the timekeeping device, to update the calendar and to set the timekeeping device hands on time.
  • the timepiece according to the invention further comprises an additional device that uses the minute counter 11, and which is powered at least in part by a BA auxiliary cylinder ( figure 2 ) arranged in the watch movement.
  • the additional device comprises a striking mechanism associated with a timer mechanism (not shown) which is kinematically connected to the timekeeping device of the watch movement, the ringing being triggered at the end of a time interval. preselected which is counted by the timer mechanism.
  • the auxiliary barrel BA thus provides the mechanical energy necessary for actuating the hammers of the striking mechanism, which will not be described here in more detail, while the main barrel provides the mechanical energy necessary for driving the timer.
  • the preselection of the duration to be counted is fixed by rotation of the ring 37 which acts, via a gear train (not shown) on a needle 19 with three branches of different lengths and angularly offset by 120 °. Only one of the branches is represented at figure 1 .
  • the three branches cooperate with a dial 13 shaped circular sector and having three concentric scales of 10 minutes each.
  • the watch 10 comprises mechanical control means MC comprising a pusher 38 located at approximately 9 o'clock and which are arranged to simultaneously switch on the additional device and arm the auxiliary barrel BA.
  • the control means MC further comprises a rocker 40 pivoted at A on the movement stage (not shown) for the engagement control of the additional device and a winding bar 42 which extends through the movement between the pusher 38 and the auxiliary barrel BA to arm the latter.
  • the pusher 38 acts simultaneously on the rocker 40 and on the winding bar 42 via an articulated lever 43 interposed between the rocker 40 respectively the winding bar 42 and the end 38a of the push rod 38
  • the stroke of the pusher is indicated by the length L at the figure 2 .
  • the lever 43 has the shape of a blade substantially curved in the plane.
  • the lever 43 is articulated in B on the platen of the movement by one of the ends in a known manner.
  • the lever 43 further comprises three pins 44, 45 and 46 distributed along its length and extending perpendicular to its surface. Two of these pins 44 and 45 respectively serve as support points for the transmission of the movement of the lever 43 to the latch 40 and to the reinforcing bar 42.
  • the third pin 46 serves as a fulcrum for a return spring 47 which tends to pivot the lever 43 in the direction of the arrow F.
  • the pin 45 which acts on the arming bar 42 also forms a fulcrum for the end 38a of the rod pusher 38.
  • the arming bar 42 has at its distal end a rack 42a which meshes with a pinion 48 connected to the shaft of the auxiliary barrel BA, while its proximal end cooperates with the articulated lever 43.
