Definitions

  • the present invention relates to the field of mechanical watchmaking. It relates more particularly to a timepiece provided with a particular regulating organ.
  • the drive member that gives energy to the movement is a spring housed in a drum to form a barrel.
  • the unwinding of the barrel is controlled by a dispensing member called exhaust which also aims to maintain and count the oscillations of the regulating member formed by a balance associated with a spiral spring.
  • the assembly consisting of the exhaust and the spiral spring is called assortment.
  • Such a cardan system can not be transposed inside a movement for a portable timepiece, because it is too large.
  • the problem of the connection between the work train and the part suspended by the cardan remains, at present, insoluble.
  • the object of the present invention is to propose a timepiece whose operation of the regulating organ is not exposed to variations in gravitation and does not have the abovementioned disadvantages.
  • the invention relates to an assortment for a timepiece comprising an escapement mechanism which is intended to drive a finishing gear train of a watch movement which defines a reference plane, and a pendulum cooperating with the exhaust mechanism.
  • the balance is mounted in a frame, this frame pivoting about a first axis relative to the reference plane, and the orientation of said frame relative to this first axis is a function of the gravitational force of the earth.
  • FIG 1 On the figure 1 a second wheel 10 of the work train of a watch movement.
  • the support 12 is made by means of three arms, better visible on the figure 2 , which intersect on an axis orthogonal to the wheel 10 and passing through its center.
  • the wheel 10 rotates a shaft 14, oriented perpendicular thereto.
  • this shaft 14 is integral with the wheel 10 at a first of its ends. At its other end, it ends with a first bevel gear 16, which is also attached to it.
  • the tree defines an axis AA.
  • a connecting member is mounted at the end of the shaft 14, on the side of the pinion 16. It is formed of two washers 18a and 18b, advantageously of similar dimensions, each provided with two lugs 20a and 20b oriented orthogonally with respect to the washers and pierced with a hole 22a and 22b.
  • the first washer 18a is mounted in a groove 24 formed on the shaft 14 in which it is slidable about the axis AA.
  • the groove is positioned in a plane orthogonal to AA.
  • the second washer 18b is disposed vis-à-vis the first 18a.
  • the holes 22a and 22b of the lugs 20a and 20b of one and the other are aligned along an axis BB and form hinges with studs 26 which pass through them.
  • the second washer 18b is rotatable along the axes AA and BB with respect to the shaft 14.
  • a watch movement assortment is disposed in a frame 28, formed of two bridges connected by pillars 32.
  • the exhaust is of the force type constant.
  • This type of organ is particularly well known to those skilled in the art and need not be described in detail here.
  • the figures show, by way of example, a distributor member consisting of an anchor escapement.
  • the latter mainly comprises an anchor 34 which periodically retains an escape wheel 36.
  • This is secured to an exhaust pinion 38 carrying an auxiliary spiral spring 40 which provides the function of "constant force" of the exhaust.
  • the anchor cooperates with a balance spring 42.
  • the frame 28 comprises, in an area between the axis of the escape wheel 36 and that of the balance spring 42, an annular portion 44 provided with a hole.
  • the frame 28 is mounted integral with the washer 18b so that the hole 22b is aligned with the hole of the portion 44.
  • the annular portion 44 is welded to the washer 18b.
  • the washer 18b has come from one piece with the bridge and ends with the two lugs 20b.
  • a second bevel gear 46 is pivotally mounted on the hole of the second washer 18b and on that of the portion 44. It is provided with a shaft 48 which passes through the washer 18b and the annular portion 44, and terminates in a pinion 50, of which only one tooth is visible in the drawing, which meshes with the exhaust pinion 38.
  • the regulating member is kinematically connected to a cylinder that comprises the movement of the watch, via the second wheel 10, the shaft 14 and all the gears 16, 46 and 50.
  • the exhaust receives the energy dispensed at the base by the barrel and let periodically escape a parcel of this motive power to return to the regulating organ that makes him lose the friction.
  • the device When the watch is horizontal, the device is as shown on the Figures 2 and 3 that is, the bevel gears 16 and 46 mesh completely with each other.
  • the center of gravity of the frame bearing the regulating organ shall be situated in a plane passing through the axis BB and oriented in the direction of the earth's gravitational force, that is to say, when the watch is horizontal, in a orthogonal plane with respect to the finishing gear.
  • This plane is called reference plane P r .
  • the purpose of the device is to allow the frame 18, when the wearer of the watch moves, to move so that the regulating member remains in a horizontal position relative to a terrestrial reference.
  • the frame pivots about the axis BB so that the center of gravity remains in the reference plane.
  • the two bevel gears abut one another. If the center of gravity moves on the reference plane side which includes the shaft 14, the two bevel gears abut one another. If the center of gravity remains in a plane orthogonal to the reference plane which contains the center of the first washer 18a, then the device is in a metastable position in which the regulating member may not be horizontal. However, under real conditions, a slight imbalance of the frame relative to this metastable position provides a first pivoting rotation of the frame about the axis AA by rotation of the first washer 18a on the groove 24. The center of gravity then returns to the other side of the reference plane and, as described above, the frame pivots around the BB axis so that the center of gravity remains in the reference plane .
  • the two pivoting around the axes AA and BB take place simultaneously and combine.
  • the latter carries weights 52, in particular arranged at the furthest point from the axes of rotation.
  • the weights are shown near the escape wheel 36.
  • they can slide on the frame 28 to facilitate the adjustment of the device.
  • the height between the support structure 12 and the axis BB must be greater than the largest dimension orthogonal to the reference plane of the parts of the set or frame located on the side of the reference plane does not include the shaft 14.
  • this maximum dimension is defined by the distance between the balance spring 42 and the reference plane.
  • the movement in which the device according to the invention is integrated must not include elements that could hinder the movement of the frame 28 and assortment.
  • the coefficient of friction between the first washer 18a and the shaft 14 must be greater than the friction of the assortment, thus ensuring that the exhaust pinion 36 transmits its energy well to the gear train and does not cause the rotation of the frame 28 around the tree 14.
  • the escape wheel pivots in the direction indicated by the arrow Z on the figure 1 .
  • the pinion 50 therefore rotates in the opposite direction.
  • the frame 28 pivots in the opposite direction to that of the arrow Z about the axis AA
  • the escape wheel 36 is delayed with respect to its normal movement.
  • the auxiliary spring 40 stores energy and then restores it gradually.
  • the escape wheel 36 takes the advance compared to its normal movement.
  • the auxiliary spring 40 expands and the barrel is immediately unwound faster to compensate for the decrease in torque. In both cases, the auxiliary spring 40 serves as an intermediate so that the torque provided to the escape wheel is constant.
  • the entire set also provided with a constant force escapement, is mounted in a first frame 60 comprising, in the example shown, two pillars 62 and a central axis CC.
  • the upper deck 68a associated with an intermediate bridge 69 carries an anchor 72, while an escape wheel 73 and an escape pinion 75 associated with its auxiliary spring, are mounted on the central axis.
  • the pinion 75 is only partially represented, while the spring is not visible.
  • the exhaust pinion 75 is located between the first 60 and the second 66 frame.
  • the second frame is interposed between the wheel 73 and the exhaust pinion 75. In this way, the pinion 75 facilitates the kinematic connection between the exhaust and the finishing train, because it avoids impeding the rotation of the second frame 66 relative to the first.
  • the anchor 72 cooperates with a plateau pin 74.
  • the plate pivots between the upper bridge 68a and the intermediate bridge 69 and is provided with a shaft 76 which passes through the intermediate bridge 69 and terminates in a conical gear 78.
  • the shaft 76 comprises a connecting member 80 comprising a hinge DD axis that connects it hingedly to a third frame 82. Part of the elements forming the hinge is integral or may have come from a room with the intermediate bridge 69.
  • the balance spring is mounted in the third frame 82 and integrally drives, by a shaft which passes through the frame 82, a second pinion with conical teeth 84 which cooperates with the first 78.
  • the regulating member is pivotable about the axis DD, on the one hand, but also, in solidarity with the entire assortment, around the axis CC.
  • the assembly of the second frame 66 pivots inside the first 60 whose pillars 62 are sufficiently distant from each other to allow a complete revolution of the second frame.
  • the pillars 70 of the second frame are made of a heavy material.
  • a timepiece whose regulating member, alone or associated with the distributor member, is disposed in a frame capable of being oriented along two axes by the gravitational force of the earth.
  • the plane of the balance spring remains approximately orthogonal to the direction of gravity. The differences of course generally observed in the various positions of the watch no longer exist.
  • the escapement represented is of the Swiss anchor type.
  • the skilled person can easily choose and adapt any type of exhaust without departing from the scope of the invention.
  • the skilled person can define and position stops to prevent the frames take unfavorable extreme positions.
  • the two bevel gears associated with the connecting member can be replaced, one by a spherical type gear, and the other by a plate whose edges are bent in a convex direction, these edges carrying a denture collaborating with the spherical gear.
  • Such a device can be inspired from the document SU 958048 .
  • the mechanism according to the invention like the Tourbillon Bréguet, seeks to limit the effects of terrestrial gravitation on the regulating organ. In reference and as a tribute to this prestigious predecessor, this mechanism is called Maelström.
