Definitions

  • the invention relates to a mechanical marine chronometer, comprising a generally large format watch intended to keep time on boats.
  • a mechanical marine chronometer comprising a generally large format watch intended to keep time on boats.
  • such a watch comprises, in a case, a mechanical movement driven by a barrel, such a watch is fixed to a support by means of a gimbal suspension so that the watch is tiltable in all directions. relative to the support.
  • the gimbal suspension thus ensures that the watch and more precisely the oscillator of the watch has a horizontal position regardless of the movements of the boat.
  • a gimbal suspension is fragile and does not withstand movement and shock quite badly, in particular due to the weight of the watch it is carrying.
  • a marine chronometer must be able to be used in difficult climatic conditions and must in particular be resistant to water.
  • the watch is equipped with a waterproof case.
  • winding the chronometer barrel requires manual intervention from outside the watch case.
  • a marine chronometer pivotally mounted along a first axis in a support ring comprises, for winding the barrel, a winding control member positioned outside the case.
  • the winding control member is secured to a toothed wheel which meshes with a set of teeth secured to a socket mounted in the bottom of the case.
  • the barrel pin is positioned in the sleeve and can be controlled by the control device.
  • This patent application proposes a new marine chronometer, which does not have at least one of the drawbacks of known marine chronometers as set out above.
  • the present invention proposes a marine chronometer comprising a watch mounted on a support, for example mounted tilting with respect to the support by means of a gimbal suspension; the watch comprises, in a case, a mechanical movement driven by a barrel; the watch also includes a winding control member engaged with a winding gear train of the barrel.
  • the chronometer according to the invention is characterized in that the winding control member comprises a winding control cog positioned outside the watch, secured to an axis passing through a wall of the case via a bearing, said through axle being in mesh with the barrel winding gear train.
  • the bearing allows rotation of the winding control member, in particular to allow winding of the barrel, but prohibits any movement in translation of the axis passing through the wall of the case of the watch.
  • the sealing conditions at the level of the bearing are thus the same whether the winding means is in the rest position or in the winding position.
  • the winding control gear train is positioned outside the case, it can be coupled to a winding means without intervention inside the case; sealing is thus controlled.
  • the bearing may comprise, on an inner wall, at least one groove in which is housed a seal improving the tightness of the housing.
  • the seal is for example an O-ring.
  • the seal is subjected only to radial forces due to rotations of the axis passing through the winding control member, but not to lateral forces so that the seal cannot be moved or deformed. The tightness of the case is thus perfectly maintained, including during winding of the barrel.
  • the chronometer according to the invention also comprises a coupling means comprising a coupling gear train movable between a coupling position where the watch winding control gear train and the coupling gear train are mechanically coupled and a rest position where the winding control of the watch is independent of the coupling means.
  • the coupling means makes it possible not to move in translation the winding control member linked to the barrel, for example for winding of the barrel.
  • the coupling means also comprises a retaining pin and a lifting mechanism for sliding the coupling gear train along the retaining pin between the coupling position and the rest position.
  • the lifting mechanism may for example be of the scissor type and may for example be actuated manually by a lever.
  • the winding control member and the coupling means are positioned under the case of the watch so that, when the coupling gear train is in the coupling position, the watch is resting on the coupling means.
  • the coupling gear train and its retaining pin support the weight of the watch.
  • the watch is mounted mobile, for example tiltable on a gimbal suspension, the watch is immobilized in support on the drive member. The watch is therefore locked in a position concentric with the central axis of the case, a locked position which avoids disorderly movements of the watch during transport, except as a timekeeper on a boat.
  • the chronometer can also include winding means comprising a mechanism for driving the coupling gear in rotation, to enable a user to wind the barrel.
  • the winding means may include a release mechanism suitable for isolating the coupling means from the rotation drive mechanism when the barrel has reached a raised position. This makes it possible to avoid breaking the watch and/or the winding means in the event of excessive effort by the user.
  • the invention relates to a marine chronometer comprising a watch 10 mounted on a support 1.
  • the watch is mounted tilting relative to the support by means of a gimbal suspension and is installed in a case 1.
  • the watch 10 comprises a case 11 in the form of a portion of a sphere, a case in which is housed a conventional mechanical watch movement of which the motor means, known, are formed by a barrel B engaged with a winding gear train Ba.
  • the case 11 is conventionally sealed in a sealed manner by a crystal under which are positioned a dial and hands ( fig. 1 ), as well as the watch movement.
  • the gimbal suspension of the watch 10, also known per se, is represented simply by a suspension ring 12; the mechanical connections between the ring 12 and the support are not detailed for the sake of clarity of the figures.
  • the watch according to the invention also comprises a winding control member 13 comprising a winding control gear train 14 positioned outside the watch.
  • the winding control train 14 comprises a flange 14a, and a plurality of teeth 14b cut on a bottom face of the flange 14 of the winding control train.
  • the gear train 14 is integral with a shaft 15 passing through a wall of the case 11 via a bearing 11a; and the through axle 15 engages with the winding gear train (Ba) of the barrel.
  • the bearing 11a comprises, on one inner wall, two grooves in which are housed two O-rings 11b completing the sealing of the housing 11 at the level of the axis 15.
  • the coupling gear 21 comprises a flange 21a and a plurality of teeth 21b cut on a top face of the flange 21a of the coupling gear 21 and arranged so that the coupling gear 21 can rotate the winding control gear train 14 (mechanical coupling by dog clutch) when the coupling gear train is in the winding position.
  • the coupling means 20 also comprises a retaining pin 22 and a lifting mechanism 30 for sliding the coupling gear train 21 along the retaining pin 22 between the coupling position and the rest position.
  • the winding control member 13 and the coupling means 20 are positioned under the case of the watch so that, when the coupling gear train is in the coupling position, the watch is resting on the drive member 20.
  • the lifting mechanism 30 is of the scissor type ( figs. 3-4 ), capable of being set in motion manually by a user via a lever 33.
  • the mechanism 30 here comprises four pairs of connecting rods ( figs. 2-4 ).
  • Each pair of connecting rods comprises two connecting rods 34, 35 associated in scissors and the connecting rod pairs are associated two by two.
  • a connecting rod 34 comprises a foot articulated by a pivot connection with the support 1 and a head articulated by a pivot connection with a head of an associated connecting rod 35; said associated connecting rod 35 also comprises an articulated foot mechanically by a pivot connection 35a with the connection tube 21a of the cradle and with a foot of another connecting rod 35 of a pair of associated connecting rods.
  • the lever 33 has meanwhile in the example shown has two sides with a substantially T-shape; a free end of a large side of the lever forms a handle 37 for gripping; the two ends 36a, 36b of the short side 38 form abutments and are an aesthetic element; a stop 36a in the rest position and the other stop 36b in the holding and/or winding position.
  • each pair of connecting rods 34, 35 form a closed scissor ( fig. 3-4 ).
  • the chronometer winding means according to the embodiment shown in the figures is used as follows. In rest position ( figs. 3-4 ), drive member 20 rests on support 1 and is remote from the watch; the winding control member 13 of the watch and the drive member 20 are remote from each other so that there is no mechanical coupling between them; the watch is thus free to move on the gimbal suspension.
  • the drive member 20 When the user pulls on the handle 37 of the lever 33, the drive member 20 is lifted by the lifting mechanism 30; when the drive train 21 of the member 20 comes into contact with the winding control member 13 of the watch, and more precisely with the winding control train 14, the train 21 causes the train 14 to pivot and the watch up to the winding position where the axis of the gear train 21 and the axis of the gear train 14 of the watch are aligned.
  • the mechanical coupling between gear train 21 and gear train 14 is maximum, the watch rests on gear train 21 so that the gimbal suspension is relieved of the weight of the watch.
  • the watch is thus immobilized on the coupling means 20, for example to be transported or reassembled.
  • the link cog 22a is meshed with the drive cog 43a
  • the cog 21 is meshed with the coupling cog 43a so that a rotation of a key at the free end 41a of the axis 41 rotates the coupling gear 43a, which in turn rotates the connecting gear 22a, the retaining pin 22 and the drive train 21.
  • the drive train 21 drives in rotation the winding control member 13 by mechanical coupling, which makes it possible to wind the barrel of the watch.
  • a scissor-type mechanism is used to raise and lower the drive means 20 but it is understood that according to variants other types of lifting mechanisms can be envisaged, as for example one could provide a mechanism of the simple knee type or with two connecting rods or even a mechanism of the knee press type or even a system with jacks, for example screw jacks, telescopic or not.
  • Such mechanisms are described in particular on pages 144 and 145 of the work entitled “Elementary Mechanisms” edited by Decoopman, ISBN No. 97823650027.
