Definitions

  • the invention relates to a marine mechanical chronometer, comprising a watch generally large format for keeping time on boats.
  • a marine mechanical chronometer comprising a watch generally large format for keeping time on boats.
  • such a watch comprises, in a housing, a mechanical movement driven by a cylinder such a watch is fixed to a support via a cardan suspension so that the watch is tilting in all directions by report to the support.
  • the cardan suspension thus ensures the watch and more precisely the oscillator of the watch a horizontal position regardless of the movements of the boat.
  • a cardan suspension is, however, fragile and supports movement, shocks, especially because of the weight of the watch it carries.
  • a marine chronometer must be able to be used in difficult climatic conditions and must in particular withstand the water.
  • the watch is equipped with a waterproof case. The winding of the stopwatch cylinder however requires manual intervention from outside the case of the watch.
  • Patent publication D1 CH2960 discloses a case for a marine chronometer with a mechanical winding mechanism.
  • a pinion F of ratchet teeth On the rocket axis is fixed a pinion F of ratchet teeth.
  • a winding pinion F ' Similarly slidably mounted to mesh with the pinion F in the winding position.
  • a toothed wheel D is mounted on the axis of the winding pinion F ', said toothed wheel being coupled to a conical pinion C fixed at one end of a winding stem.
  • the tightness of the zone where the axis carrying the winding pinion passes through the watch case is generally provided by a seal ; this sealing is not always guaranteed regardless of the conditions of use.
  • the efficiency of the seal is reduced during the translation of the axis carrying the pinion F 'winding.
  • a winding system such as that described in D1 is unreliable because of a possible sliding between the toothed wheel D and the conical drive wheel C.
  • the present patent application proposes a new marine chronometer, not exhibiting at least one of the disadvantages of known marine chronometers as set forth above.
  • the present invention provides a marine chronometer comprising a watch mounted on a support, for example mounted tilting relative to the support by means of a cardan suspension; the watch comprises, in a case, a mechanical movement driven by a barrel; the watch also comprises a winding control member engaged with a wheel winding cylinder.
  • the chronometer according to the invention is characterized in that the winding control member comprises a winding control gear positioned outside the watch, integral with an axis passing through a wall of the housing via a bearing, said traversing axis being engaged with the winding train of the barrel.
  • the bearing allows the rotation of the winding control member, in particular to allow the winding of the barrel, but prohibits any displacement in translation of the axis passing through the wall of the watch case.
  • 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 train is positioned at outside the housing, it can be coupled to a winding means without intervention inside the housing; the tightness is thus controlled.
  • the bearing may comprise, on an inner wall, at least one groove in which is housed a seal improving the sealing of the housing.
  • the seal is for example an O-ring.
  • the seal is subjected only to radial forces due to rotations of the thru axle of the winding control member, but not to lateral forces so that the seal can not be moved or deformed. The tightness of the housing is thus perfectly maintained, including during the winding of the barrel.
  • the chronometer according to the invention may also comprise a coupling means comprising a mobile coupling train between a coupling position where the winding control wheel of the watch and the coupling gear are mechanically coupled and a rest position where the gear train 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 connected to the barrel, for example for winding the barrel.
  • the coupling means also comprises a holding pin and a lifting mechanism for sliding the coupling gear along the holding axis between the coupling position and the rest position.
  • the lifting mechanism can be for example scissors type and can be for example manually operated 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 is in the coupling position, the watch bears on the coupling means.
  • the coupling gear and its holding pin support the weight of the watch.
  • the watch is mounted movably, for example tilting on a cardan suspension, the watch is immobilized in support on the drive member.
  • the watch is locked in a concentric position to the central axis of the housing, locked position which avoids the disordered movements of the watch during transport, off duty time on a boat.
  • the stopwatch may also include a winding means comprising a mechanism for rotating the coupling gear, to allow a user to wind the barrel.
  • the winding means may comprise a disengaging mechanism adapted to isolate the coupling means of the rotary drive mechanism when the cylinder has reached a raised position. This avoids breaking the watch and / or the winding means in case of excessive effort of the user.
  • the invention relates to a marine chronometer comprising a watch 10 mounted on a support 30.
  • the watch is mounted tilting relative to the support via a cardan suspension and is installed in a housing 1.
  • the watch 10 comprises a housing 11 in the form of a sphere portion, housing in which is housed a classic mechanical watch movement of the watch whose known motor means are formed by a cylinder B engaged with a winding gear Ba.
  • the casing 11 is closed in a sealed manner by an ice under which are positioned a dial and hands ( Fig. 1 ), as well as the watch movement.
  • the cardanic suspension of the watch 10, also known per se, is represented simply by a ring 12 of suspension; the mechanical links between the ring 12 and the support 30 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 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 an axis 15 passing through a wall of the housing 11 via a bearing 11a; and the traversing axis 15 is engaged with the winding train (Ba) of the barrel.
  • the bearing 11a comprises, on an inner wall, two grooves in which are housed two O-rings 11b completing the sealing of the housing 11 at 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 train 14 (mechanical coupling by interconnection) when the coupling gear is in the reassembly position.
  • the coupling means 20 also comprises a holding pin 22 and a lifting mechanism 30 for sliding the coupling gear 21 along the holding 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 is in the coupling position, the watch bears against the driving 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 rods 34, 35 associated in scissors and the rod pairs are associated in pairs.
  • a connecting rod 34 comprises a foot articulated by a pivot connection with the support 30 and a head hinged by a pivot connection with a head of an associated rod 35; said associated rod 35 also comprises a foot articulated mechanically by a pivot link 35a with the connecting tube 21a of the cradle and with a foot of another rod 35 of a pair of associated rods.
  • the lever 33 has meanwhile in the example shown two sides with a substantially T-shaped; a free end of a large side of the lever forms a handle 37 for gripping; both 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 position and / or reassembly.
  • each pair of connecting rods 34, 35 forms a closed chisel ( Fig. 3-4 ).
  • a traction / rotation on the handle 37 of the lever causes the simultaneous opening of the pairs of rods, driving the gear 21 in translation in the direction of the holding pin 22 to the holding position: the control member of reassembly 13 is then supported on the drive member 20 comprising the gear 21 and; the watch is no longer only supported on the cardan suspension and is thus immobilized.
  • the chronometer winding means according to the embodiment shown in the figures is used in the following manner.
  • the driving member 20 rests on the support 30 and is remote from the watch; the winding control member 13 of the watch and the drive member 20 are spaced from each other so that there is no mechanical coupling between them; the watch is thus free of movement on the cardan 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 driving gear 21 of the member 20 comes into contact with the winding control member 13 of the watch, and more precisely with the winding control gear 14, the gear 21 rotates the gear 14 and the shows up to the winding position where the axis of the gear 21 and the axis of the wheel 14 of the watch are aligned.
  • the mechanical coupling between the gear train 21 and the gear train 14 is maximal, the watch rests on the gear train 21 so that the cardan 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 gear train 21 is engaged with the coupling gear 43a so that a rotation of a key at the free end 41a of the gear wheel
  • the shaft 41 rotates the coupling gear 43a, which in turn rotates the linkage train 22a, the holding 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 scissors-type mechanism is used to raise and lower the driving means 20, but it is understood that according to variants of other types of lifting mechanisms may be envisaged, example we could provide a mechanism of the simple knee type or two connecting rods or a mechanism of the knee press type or a jack system for example telescopic screw jacks or not.
  • Such mechanisms are described in particular in pages 144 and 145 of the book entitled “Elementary Mechanisms” edited by Decoopman, ISBN 97823650027 which are incorporated herein by reference.
