Definitions
- the invention relates to a mechanism for advance by periodic jump of a pivoting cage around a cage axis, said cage carrying an escape wheel and an escape pinion and an anchor cooperating with said wheel. escapement and with a sprung balance, said mechanism comprising:
- pivoting stop means arranged to cooperate with said retaining means, for, according to the pivoting angular position of said pivoting stop means, allow or prohibit the pivoting of said retaining means
- said retaining means having a trajectory interfering with that of said stopping means.
- the invention relates to a skip advance mechanism of a second dead carousel cage.
- the invention also relates to a carousel comprising a carousel cage and such a mechanism.
- the invention relates to the field of watchmaking.
- the Swiss patent CH 47 297 in the name of Pellaton-Schild describes, as early as 1907, a second lightning dead, with two field wheels connected to each other by a spiral spring, and one of which drives the pinion. exhaust, which is coaxial and attached to a star with protruding teeth.
- the engine cylinder drives, through a gear, a pinion carrying a whip, which bears each time on a tooth of the star, their relative pivoting generating a position where the whip escapes the tooth, lightning, and takes one full turn before coming back to abut another tooth of the star.
- This tourbillon mechanism comprises a pivoting cage driven by a drive wheel, this tourbillon cage is coaxial with a pivoting beam provided with a balance spring balance and with a fixed second wheel, and is carrier, in three separate eccentric positions, an eccentric escapement wheel, a first anchor, and a stop wheel which meshes with this fixed second wheel.
- the escape wheel cooperates with this first anchor provided with two pallets.
- a constant force device comprises a spiral escapement spring, integral at one end with the escape wheel, and at a second end with a force compensation disc. The latter is integral in rotation with an armature ring of the exhaust spring, and a pinion of armoring ring which is associated with it and which cooperates with the fixed second wheel.
- a Reuleaux cam of substantially triangular shape cooperates with a fork that includes a second anchor coaxial with the balance, which pivots about the axis of the tourbillon cage.
- This second anchor comprises a cam arranged to cooperate with a fork and a dart carried by the first anchor.
- the second anchor comprises two vanes arranged to cooperate with radially projecting teeth that includes the stop wheel.
- the balance is driven under the effect of the preload of the exhaust spring, and is returned by the balance spring spiral.
- the balance carries a number of alternations, for example five with a wheel of fifteen teeth, before the stop wheel and the tourbillon cage are released by the cam Reuleaux and the second anchor focused on the pendulum.
- the stop wheel performs a given angular deflection, for example 90 °, before being stopped again by one of the pallets of the second anchor focused on the balance.
- this pivoting of the stopwheel drives that of the tourbillon cage. .
- this pivoting also causes the pivoting of the arming ring which is fixed on the cage and also meshes with the seconds wheel, resulting in the re-tensioning of the spiral escapement spring, because the escape wheel is then blocked by the first anchor.
- the exhaust spring is periodically extended. He accumulates well enough of energy to deliver a sufficient torque to maintain oscillations of the balance.
- This compensation mechanism is intended to deliver a constant torque.
- the first end of the spiral escapement spring is fixed on a first pin secured to a first ferrule of exhaust spiral spring connected to the escape wheel.
- the second end of the spiral escapement spring is fixed on a second pin integral with a second movable spiral escapement spring ferrule.
- the spiral exhaust spring once tensioned, exerts a force on the first pin, and thus exerts a torque on a first arm that includes the force compensation disk that includes the constant force device.
- the latter comprises a first and a second arm, arranged to bear respectively on the first and the second pin, and the bearing faces of these arms are aligned with each other but in an off-axis direction relative to the axis of the escape wheel.
- the second arm presses on the second pin and transmits the torque to the fixed shell spiral spring and the escape wheel.
- the lever arms of the forces exerted by and on the pins are variable depending on the angular position of the force compensation disk, which ensures a constant torque on the escape wheel, despite the loss of tension of the exhaust spring during the stop of the entire train from the spring to the stop wheel.
- the patent application EP 1 772 783 in the name of MONTRES BREGUET SA describes a watch movement comprising a constant-force device, and a dead-minute display on the center wheel, which is capable of driving a vortex in good conditions. with the constant force device. It comprises a mobile of average, which makes a turn in several minutes, and which constitutes the input element of a device with constant force.
- the output element of this spiral spring device is constituted by a second wheel of average, which meshes with the pinion of seconds, which is secured to a tourbillon cage
- This second wheel of medium is integral with a star, which releases periodically , in this case once a minute, a stop gear meshing with the average input moving, which cooperates with the center wheel, which thus makes a jump per minute. This mechanism minimizes the transmission of shocks between the constant force device and the exhaust.
- the constant force device provides an advantage, which is to ensure a relatively constant engine torque to the exhaust, but which necessarily represents a large footprint and cost.
- the invention proposes to provide a more economic alternative carousel second dead, using the simplicity of star and whip devices, but reducing shocks, and requiring the least possible additional components, and in the smallest possible volume .
- the invention relates to a mechanism for advance by periodic jump of a pivoting cage around a shaft axis, said cage carrying an escape wheel and an escape pinion and an anchor cooperating with said escape wheel and with a hairspring, said mechanism comprising:
- a motion transmission train driven by an input drive means for pivotally driving said cage and said exhaust pinion;
- - Pivoting retaining means arranged to cooperate with said cage for, as they rotate or are stopped, allow or prohibit the pivoting of said cage;
- pivoting stop means arranged to cooperate with said retaining means, for, according to the pivoting angular position of said pivoting stop means, allow or prohibit the pivoting of said retaining means
- said retaining means having a trajectory interfering with that of said stopping means
- said retaining means are, as well as said stop means, external to said cage, and further characterized in that said retaining means comprise a whip gear carrying a whip arranged to cooperate with said means of stopping and interfering trajectory with said stopping means, said whip gear cooperating with a toothing that includes said cage, via an inverting mobile.
- said motion transmission gear meshes permanently with said exhaust pinion to rotate it about an exhaust axis carried by said cage, and tends to drive said cage pivotally about said cage axis via said exhaust axis;
- said cage continuously pushes, under the action of said motion transmission train, said retaining means against said stop means, to rotate said cage when said stop means pivotally release said retaining means, and for stopping said cage when said stopping means blocks said retaining means.
- said stop means comprise a star integral with a permanently driven star pinion, and in that said retaining means comprise a whip. secured to a whip gear meshing directly or indirectly with said cage, the trajectory of said whip interfering with that of said star, to rotate said cage when said star releases said whip, and stop otherwise.
- said star gear is permanently driven by a star drive train which is connected to said motion transmission train, directly or via said exhaust pinion.
- said retaining means and said stop means are arranged so as to make said cage one jump per second.
- the invention relates to a skip advance mechanism of a second dead carousel cage.
- This new achievement is distinguished by its simplicity, the low number and low cost of additional components, and their very small footprint.
- the invention also relates to a carousel comprising a carousel cage and such a mechanism.
- the invention also relates to a timepiece comprising such a mechanism, or such a carousel.
- FIG. 1 shows schematically and in plan view, a jump advance mechanism according to the invention, in a preferred embodiment
- - Figure 2 shows schematically, partially, and in plan view, a timepiece comprising a jump advance mechanism according to a second embodiment
- Figure 3 shows a detail of Figure 2.
- the advance mechanism 100 is a periodic jump feed mechanism of a display means of a temporal magnitude, in particular of the second, comprising:
- This cage 30 pivots about a cage axis, and carries an exhaust mechanism 40 comprising an escape wheel 42 and an escape gear 41 and an anchor 50, which cooperates with the escape wheel 42 and with a balance spring 80.
- the escape wheel 42 and the exhaust pinion 41 are coaxial.
- the motion transmission train 20 is arranged to permanently pivot the exhaust pinion 41 and the cage 30 when the latter is free to rotate.
- the principle of the invention is to constrain the pivoting movement of the cage at a certain period, which is not necessarily determined by the frequency of the oscillator as is the case usually, but which is chosen at a particular rate, for example in the embodiment described below where the cage passes from second to second by marking the second.
- the mechanism 100 comprises:
- - Retaining means 70 preferably pivoting, arranged to cooperate with the cage 30 for, depending on whether they pivot or are stopped, allow or prohibit the pivoting of the cage 30;
- Stop means 60 preferably pivoting, arranged to cooperate with the retaining means 70, for, depending on the position of the stop means 60, in particular the angular position of pivoting, allow or prohibit the movement of these means of restraint 70 including the pivoting movement when the latter are pivotable.
- the retaining means 70 have a trajectory interfering with that of the stop means 60.
- the retaining means and the stop means 60 are arranged outside the cage 30, that is to say that they are not carried by the cage 30. Indeed, not to complicate unnecessarily the onboard mechanism, and to avoid interference in the interior volume of the cage, the invention proposes to provide a more economical alternative carousel second dead, using the simplicity of star and whip devices, but reducing shocks , and requiring the least possible additional components, and under the smallest possible volume, this volume being preferably disposed outside the cage.
- the motion transmission train 20 meshes permanently with the exhaust gear 41 to rotate it about an exhaust axis carried by the cage 30, and it tends to drive the cage 30 to pivot about the axis of cage through the exhaust shaft.
- the cage 30 is constantly pushing, under the action of the motion transmission train 20, the retaining means 70 against the stop means 60, to rotate the cage 30 when the stop means 60 release, in particular pivotally, the retaining means 70, and to stop the cage 30 when the stop means 60 locks these retaining means 70.
- the motion transmission train 20 is the only drive member pushing the retaining means 70 against the stop means 60, which advantageously avoids any means of additional energy storage by spring or other .
- the retaining means 70 comprise a whip gear 75 carrying a whip 76 arranged to cooperate with the stop means 60 and of interfering trajectory with said stop means 60, this whip gear 75 cooperating with a toothing 31 that includes the cage 30, via an inverting mobile 71.
- the input drive means 10 is conventionally arranged to receive energy in the form of a torque transmitted by energy storage means such as barrel, weight, or the like.
- the input drive means 10 is a wheel of high average 1 1, which performs one revolution per hour, and comprises N1 teeth, for example here 96 teeth. This wheel of high average 1 1 rotates continuously, as long as the energy storage means are able to deliver energy to the mechanism.
- the motion transmission train 20 is of very variable composition. It comprises here a pinion of average 21 and a wheel of average 22, respectively of N2 and N3 teeth, in Example 8 and 90 teeth.
- the average pinion 21 meshes with the wheel of great average 1 1.
- This retaining star 65 therefore rotates continuously under the action
- This second gear 23 is secured to a second wheel 24 having N9 teeth.
- This second wheel 24 meshes conventionally with an exhaust pinion 41 having N10 teeth.
- the cage 30 is preferably a carousel cage, as visible in the figures and has a toothing 31 with N7 teeth, and is pivotable about a cage axis.
- This cage 30 comprises a point of attachment of a first end of a balance springs balance 82 whose other end is fixed to a rocker 81 movable pivotally, preferably around this shaft axis, in the latter case the cage 30 is mounted coaxially with the spring balance 80 which is constituted by the balance 81 and the balance spring balance 82.
- This cage 30 carries:
- the escape mechanism 40 comprising an escapement wheel 42 pivoting about an escape axis parallel to this cage axis, preferably eccentrically in a preferred embodiment as visible in the figures;
- An anchor 50 pivoting about an anchor axis parallel to the cage axis and arranged to cooperate with the escape wheel 42, preferably eccentrically in a preferred embodiment as visible in the figures.
- the exhaust pinion 41 is permanently driven by the second wheel 24.
- This second wheel 24 exerts on the exhaust pinion a pair which tends, at a time on the one hand to rotate the exhaust pinion 41 on itself, to regulate, by means of the escape wheel 42 and the anchor 50, the oscillation of the balance-spring 80, and on the other hand to rotate the axis of this exhaust pinion 41 about the pivot axis of the second wheel 24.
- the pivot axis of the second wheel 24 coincides with the axis of pivoting of the cage 30 which carries the pivot axis of the exhaust pinion 41.
- the pivoting of the second wheel 24 therefore always tends to cause a pivoting of the cage 30 in the same direction as that of the second wheel 24, here in the clockwise direction. Therefore, if an obstacle prohibits the pivoting of the cage 30, only the movement of pivoting of the exhaust pinion 41 about its axis takes place, the regulation of the oscillator is never interrupted. If we release the pivoting of the cage 30 by removing the obstacle, both the cage 30 pivots in the same direction as the second wheel 24, and the exhaust pinion 41 pivots about its axis in the same way as in the previous case.
- the retaining means 70 are arranged to cooperate with the cage 30 for, depending on whether they are in motion or are at a standstill, allow or prohibit the pivoting of the cage 30; in the present embodiment, they comprise a retaining mobile 77.
- This retaining mobile 77 comprises a wheel or a pinion meshing with the toothing 31 that includes the cage 30.
- the stop means 60 are arranged to cooperate with these retaining means 70, for, according to the angular position of pivoting of these stop means 60 when they are pivoting, allow or prohibit the pivoting of the retaining means 70.
- these stop means 60 comprise a retaining star 65, integral with a star pinion 64, as described above, permanently pivoted and each tooth 66 is arranged to cooperate with a whip 76 belonging to the retaining means 70, and to stop and periodically release the whip 76, according to the angular position of the retaining star 65.
- This drive of the star pinion 64 can be carried out, preferably as visible in the present embodiment, by the transmission train 20, directly or through the exhaust pinion 41.
- the pivoting retaining means 70 consist, in the example of the figures, of a whipstock 74 comprising a whip pin 75 comprising N14 teeth, and which carries at least one whip 76, able to pivot about the axis of the whip.
- movable whip 74 and arranged to cooperate with a retaining star 65.
- the trajectory of the whip 76 interferes with that of the star 65, to rotate the cage 30 when the star 65 releases the whip 76, and stop it otherwise.
- the whip gear 75 meshes directly or indirectly with the toothing 31 of the cage 30.
- the whip 76 is kept under tension, resting on a flange 66 of the retaining star 65, until it reaches an angular position allowing the release of the whip 76, or the whip arm if the whip 76 is multi-arm, double arm or star for example.
- the whip 76 is a multiple arm whip, or star, which allows a great flexibility of use, and allows to easily obtain the desired jump value on the cage.
- the design of the invention makes it easy to choose the size that it is desired to display with a jump, for example the fifth of a second, the ten seconds, the minute, or other, by a simple judicious calculation of the gear , as well as by the choice of the number of arms of the whip 76.
- the invention also authorizes a derivative design, with a cage rotation of a duration other than a minute, for example in thirty seconds.
- the retaining device 77 comprises an inverting mobile 71 in engagement with the toothing 31, on the one hand, this inverting mobile 71 consisting of an inverter pinion 72 meshing with the wheel 31, and an inverter wheel 73 secured to this reversing gear 72, and with the whipstock 74 on the other hand.
- the whipless gear 75 meshes with the reversing wheel 73.
- the whip gear 75 then co-operates with the toothing 31 of the cage 30 via the inverting mobile 71.
- the use of such a mobile inverter is advantageous because it provides a particular advantage, which lies in the shock absorption.
- this mobile inverter is in the form of an elastic pinion, for example with S-arms, or elastic flexible arms, or with a radiated structure comprising thin elastic arms, or alternatively a pinion having slots, or an annular portion of elastic or rubbery material, or the like.
- the mobile inverter can also to be an odd numbered gear train.
- the mobile inverter 71 comprises at least one such elastic pinion.
- the inverting mobile 72 makes it possible to rotate the whipstock 74 in the same direction as the cage 30.
- This design is advantageous because it makes it easy to choose the size that you want to display with a jump, whether it is for example the fifth of a second, the ten seconds, the minute, or other, by a simple judicious calculation of the train. It also allows a derivative design with a cage turn in a duration other than a minute, for example in thirty seconds.
- the number of revolutions per second ⁇ effected by the star 65 is the result of the calculation relating to the transmission train 20 and to the star driver 61:
- the gear examples presented here correspond to a frequency of the oscillator of 3 Hz, with a cage 30 equipped with a gear 31 of 180 teeth, and rotating in one minute.
- a whip with n arms, for example n 2 as visible in FIG.
- FIGS. 2 and 3 illustrate a second embodiment, without an inverting gear, and with a whip having two whip arms, whipstock 74 then makes a U-turn before a whip arm returns to rest on a wing 66 of the star 65.
- FIG. 3 illustrates the very small dimension of the star 65 and the whipstock 74 with respect to the gear train and to the cage 30.
- the transmission train 20 is identical to that of Figure 1, and the exhaust mechanism 40.
- this variant embodiment does not include an inverting mobile 71, the whipstock 74 comes into direct contact with the toothing 31 of the cage 30.
- the period T is identical to that of FIG.
- the mechanism 100 is a mechanism without energy storage spring, it is in particular composed of rigid elements, which is advantageous in terms of maintenance in particular. No problem of energy storage here requires the presence of elastic elements in the mechanism 100.
- the possible presence of elastic elements, or partially elastic, may be useful for reasons of damping as the reversing pinion mentioned above, but the possible elastic function of such components is strictly limited to this damping function, with a very small strain course, of the order of one tenth of a millimeter or less.
- the mechanism 100 is advantageously composed of rigid elements or very weakly elastic elements.
- the mechanism is very simple and inexpensive while being very reliable.
- the invention relates more particularly to a mechanism 100 for advance by jumping a carousel cage to a second dead.
- the invention also relates to a carousel comprising a carousel cage 10 and such a mechanism 100.
- the invention also relates to a timepiece comprising such a mechanism 100, or such a carousel.
