Definitions

  • the present invention relates to a mechanical timepiece comprising an oscillator whose oscillating movement is maintained by a mainspring, in which a periodic energy storage device is disposed between this mainspring and an escapement associated with said oscillator.
  • periodic energy storage device comprising a seconds wheel engaged with said mainspring, an exhaust, a return for connecting the seconds wheel to the exhaust, a rocker on which said return is pivotally mounted, a stop wheel in kinematic connection with the seconds wheel, a finger integral with said rocker and whose trajectory intersects that of said stop wheel, an energy storage spring for exerting on said rocker a force tending to move said finger away from said wheel stopping, while the force exerted on said return by said mainspring serves to apply said finger against said stopping wheel with a spring rce greater than that exerted by said storage spring, so that the latter is armed until a tooth of said stop wheel abuts against said finger, allowing said storage spring to move the rocker in the opposite direction for transmitting its energy to said exhaust until the release of said
  • the energy source of the mechanical timepieces is constituted by a motor spring consisting of a spring blade wound in a barrel, its outer end being integral with the barrel drum, while its inner end is integral with the shaft of this barrel. barrel.
  • the motor spring drives the barrel drum. This has an external toothing in engagement with the gear of the timepiece that leads to the exhaust for transmitting the force of the motor spring to the regulator. With each alternation of the sprung balance, it releases a tooth of the escape wheel which, under the pressure exerted on the wheel by the mainspring, transmits a pulse serving to maintain the oscillation of the sprung balance. .
  • a timepiece comprising a periodic energy storage device of the aforementioned type has already been proposed in the CH 21315 .
  • the disadvantage of this device is that the storage period is relatively long, so that the strength of the storage spring is reduced over such a period.
  • such a period of several seconds or even several tens of seconds would not allow to set a second hand on the axis of the seconds wheel, since this needle would make jumps of several tens of seconds and stops the same duration, so that it would no longer indicate the seconds.
  • the object of the present invention is to provide a solution to the problem of the transmission of the force of the mainspring barrel to the exhaust of a timepiece which makes it possible to remedy, at least in part, the aforementioned drawbacks.
  • this invention relates to a mechanical timepiece according to claim 1.
  • the first wheel of the usual wheel shown is the wheel of average 1 whose pinion meshes with the center wheel (not shown) itself provided with a pinion meshing with the toothing of the cylinder containing the spring engine, as in all mechanical timepieces.
  • This average wheel 1 is driven in the direction of the arrow F 1 and meshes with the pinion of a first second wheel 2 turning in the opposite direction shown by the arrow F 2 .
  • the pinion of this first wheel seconds 2 meshes with a return 4 which meshes with the pinion of a second second wheel 5.
  • the pivot axis of this second seconds wheel 5 is integral with a conventional vortex escapement 8 that need not be described here, insofar as it is not necessary for the understanding of the present invention. invention.
  • the second seconds wheel could mesh with the pinion of an exhaust wheel of a conventional exhaust.
  • the reference 4 is pivotally mounted on an equality lever 6 which is pivoted about an axis coaxial with the axis of the second seconds wheel 5.
  • This equality lever 6 is subjected to the force of a spring of periodic energy storage 7, which tends to rotate it clockwise.
  • This flip-flop 6 has a similar finger 6a in this embodiment to a pallet of an anchor of an anchor escapement, intended to engage in a ratchet toothing of a stop wheel 3 of which the pinion meshes with the first seconds wheel 2.
  • the operating cycle of the periodic energy storage device is as follows: When the pallet or the finger 6a of the equal-point rocker 6 is engaged with a radial flank of the ratchet toothing of the stop wheel 3, gear train 1-3 is stopped, so there is no more transmission of force between the first seconds wheel 2 and the return 4.
  • the force stored in the periodic energy storage spring 7 is released by rotating the equality lever 6 in the clockwise direction. until the pallet or the finger 6a of this equality flip-flop 6 is disengaged from the radial flank of the stopping wheel 3. During this movement, the flip-flop 6 transmits its energy to the pinion of the second wheel 5. Since the first seconds wheel 2 is stopped, when the equality flip-flop 6 rotates clockwise, the return 4 drives the pinion of the second seconds wheel 5 in the direction of the arrow F 3 .
  • the return 4 is therefore supported on the pinion of the second seconds wheel 5 and its drive in the direction of the arrow F 4 by the pinion of the first seconds wheel 2, pushes the pallet or finger 6a of the latch equal 6 against the inclined side of one of the teeth of the stop wheel 3 rotating in the direction of the arrow F 5 , until it comes against the radial flank of the next tooth.
  • the rocker By following the inclined flank of the tooth of the stop wheel 3, the rocker therefore moves counterclockwise, causing the periodic energy storage spring 7 to be wound, since the force exerted by this storage spring 7 on the equalizer rocker 6 is less than the force exerted on the same rocker 6 by the mainspring when the stop wheel 3 is released.
  • the cycle then starts again as previously described.
  • the second hand carried by the first seconds wheel 2 moves by jump every second.
  • the arming and disarming cycle of the equality spring 7 is not necessarily a second. It could be lengthened or shortened by changing the number of teeth of the stop wheel 3.
  • the exhaust 8 receives only the energy from disarming the equal spring 7 which is independent of the degree of winding of the mainspring.
  • the amplitude of the oscillations of the balance is independent of the force variations of the mainspring, which makes it possible to improve the isochronism of the balance. It can be seen that the storage device described comprises a small number of parts.

  1. Mechanische Uhr mit einem Oszillator, dessen schwingende Bewegung durch eine Antriebsfeder aufrecht erhalten wird, worin eine Vorrichtung zur periodischen Energiespeicherung zwischen dieser Antriebsfeder und einer mit diesem Oszillator verbundenen Hemmung (8) angeordnet ist, wobei diese Vorrichtung zur periodischen Energiespeicherung ein Sekundenrad (2) im Eingriff mit der Antriebsfeder, eine Hemmung (8), ein Zwischenrad (4) für die Verbindung des Sekundenrades (2) mit der Hemmung, eine Wippe (6), auf der das Zwischenrad (4) drehbar montiert ist, ein Anhalterad (3) in kinematischer Verbindung mit dem Sekundenrad (2), einen fest mit der Wippe (6) verbundenen Finger (6a), dessen Bahn diejenige des Anhalterades (3) schneidet, und eine Feder (7) für die Energiespeicherung umfasst, um auf die Wippe (6) eine Kraft auszuüben, die den Finger (6a) vom Anhalterad (3) wegzudrücken sucht, während die durch die Antriebsfeder auf das Zwischenrad (4) ausgeübte Kraft dazu dient, den Finger (6a) an das Anhalterad (3) mit einer Kraft anzudrücken, die grösser als die durch die Speicherfeder (7) ausgeübte Kraft ist, so dass letztere solange gespannt wird, bis ein Zahn des Anhalterades (3) am Finger (6a) zum Anschlag kommt, wodurch es der Speicherfeder (7) ermöglicht wird, die Wippe (6) in der umgekehrten Richtung zu verschieben, um ihre Energie an die Hemmung zu übermitteln, bis das Anhalterad (3) ausklinkt, das, wenn es das Sekundenrad (2) freigibt, die erneute Spannung der Speicherfeder (7) erlaubt, dadurch gekennzeichnet, dass sie ein zweites Sekundenrad (5) zwischen der Hemmung (8) und dem Zwischenrad (4) aufweist, dessen Drehachse zu der der Wippe (6) koaxial ist, und dadurch, dass das Anhalterad (3) eine Anzahl von Zähnen aufweist, die so gewählt ist, dass die Periode der erneuten Spannung der Speicherfeder (7) eine Sekunde beträgt, so dass das Vorrücken des Sekundenrades (2) durch Sprünge von einer Sekunde erfolgt.
