Definitions

  • the present invention relates to a switching device of a clock mechanism between two functional states.
  • the present invention relates to a timepiece comprising, on the one hand, a watch mechanism that can switch between a first state and a second determined state and, on the other hand, a switching device arranged to switch on command the clock mechanism between its first and second states.
  • This switching device comprises a movable switching member and a rotary control member which is arranged to be driven step-by-step in a given direction of rotation, so as to successively occupy a plurality of angular positions around an axis of rotation. rotation of this control member.
  • the switching device is arranged so that a step-by-step rotation of the rotary control member causes reciprocating movement of the movable switching member, substantially in a plane perpendicular to said axis of rotation, so that at least a part of this movable switching member moves between two radial positions for which the clock mechanism is respectively in its first state and its second state.
  • the document EP 2,602,675 describes a watch movement that includes a column wheel chronograph mechanism, the latter forming a rotary control member of the chronograph mechanism which has two functional states, namely "on" and "off".
  • the watch movement described in this prior document therefore comprises a column wheel and a clutch rocker arranged to cooperate with the column wheel in order to start or stop the chronograph mechanism.
  • the column wheel is driven in order to rotate in steps in one direction of rotation while the clutch rocker is reciprocated between two determined radial positions for which the chronograph mechanism is respectively in both states. aforementioned functionalities.
  • the known switching devices generally comprise a rotary control member consisting of a cam or a column wheel, and a movable switching member. in the form of a cam follower of one type or another and more specifically constituted by a rocker or a lever.
  • a disadvantage of such switching devices is that they all in principle require the use of prestressed springs to return and maintain the movable switching member against the cam or the column wheel.
  • Watch springs are bulky and delicate. They are subject to aging which gradually makes them lose effectiveness. This aging is also considerably accelerated by the shocks that may be experienced by the timepiece. On the other hand, by always returning the mobile switching member in abutment against the cam, the springs accelerate the wear of these two components.
  • watch springs with their small dimensions are quite sensitive to tolerances, which is an additional problem.
  • An object of the present invention is to overcome the disadvantages of the prior art which have just been described.
  • the invention achieves this goal by providing a timepiece according to the appended claim 1.
  • the switching device comprises a mobile switching member and a rotary control member respectively carrying a first magnetic structure and a second magnetic structure arranged so as to have a magnetic interaction between them which makes it possible to switch to command the clock mechanism between a first state and a second state.
  • One of the first and second magnetic structures comprises at least one first magnetic pole and the other of these two magnetic structures comprises at least one second magnetic pole and a third magnetic pole with opposite polarities and capable of interacting successively with the first magnetic pole. magnetic pole.
  • the first and second magnetic structures are arranged so that, in a first angular position of the rotary control member, a first magnetic force, generated by a magnetic interaction between the first and second magnetic poles, acts on the switching member.
  • a second magnetic force generated by a magnetic interaction between the first and third magnetic poles and thus in the opposite direction to the first magnetic force, acts on the switching member so as to recall the latter in the other of its two stable radial positions.
  • the two stable radial positions relate more specifically to an end portion of the organ. of commutation.
  • a sliding switch member it is the whole of this member which undergoes a translation movement in a plane substantially perpendicular to said axis of rotation between two stable radial positions of its center of mass.
  • Such a magnetic system has the advantage of being a non-contact system capable of alternately exerting two forces with opposite directions on the switching member.
  • the appended figures 1 to 5 illustrate a first embodiment of the invention which is constituted by a timepiece comprising a striking mechanism that can switch between a first state where the ringing is activated and a second state where the ringing is stopped. and further comprising a ring stop device provided for switching the striking mechanism between the activated state and the stopped state. This device therefore defines a switch.
  • the Figures 1 to 5 are partial views that do not show the timepiece as a whole, but only the components of its stop ring device and the few elements of the striking mechanism that interact directly with the stop ring device.
  • the Figures 1 and 2 are top plan views which show the ring stop device respectively in its disengaged position and in its engaged position. Now considering these figures in more detail, we can first see three mobiles that are part of the gear of the striking mechanism.
  • first mobile constituted by a wheel referenced 11
  • second mobile constituted by a wheel 15 secured to a pinion 13
  • third mobile which is constituted by a speed controller generally referenced 17
  • wheel 11 engraine with the pinion 13 so as to cause the second mobile
  • wheel 15 of the second mobile engraine with a peripheral toothing (not referenced) of the regulator 17.
  • timepieces ringing generally comprise a ring gear associated with a power source consists of a cylinder in which is wound a motor spring called mainspring. If the barrel was simply connected to the bell, the progressive disarming of the spring would result in a slower rhythm of the melody as it was performed. This is the reason why we have the habit of correcting this phenomenon by integrating a regulator with the gear that controls the ring. Neither the barrel nor the striking mechanism itself are shown in the figures. However, it will be understood that the barrel is arranged to cause the ring gear by means of the wheel 11, and that the ring itself is arranged downstream of the regulator 17, so as to be driven via the latter.

  • the magnetic force generated by the interaction between magnets 31 and 33 regrows the magnet 31 so that the rocker 25 pivots and moves away from the abutment 28.
  • This pivoting movement causes the lowering of the hook 29 against an external toothing of the regulator 17.
  • the switching device is in the configuration illustrated by the figure 2 where the switching member 23 is now in its second radial position in which the hook 29 is engaged in an external toothing of the regulator 17, so that the latter is immobilized and the ring gear as a whole is blocked.
