Definitions

  • the invention relates to a timepiece, in particular, a wristwatch, provided with an animation mechanism and a striking mechanism, and equipped with a stroke limiter avoiding the involuntary actuation of the mechanism of alarm.
  • a timepiece comprising a device for controlling a striking mechanism provided with an elastic transmission element.
  • a piston moves in a race comprising a rest position of the piston, a stop position of a triggering element of the striking mechanism and a braking distance of the piston.
  • the control device described in this patent application is intended to prevent the rack and the other parts of the striking mechanism connected to it from being subjected to the force applied by the user when he presses the bolt, so that to prevent a malfunction of the striking mechanism, or even damage to it.
  • the timepiece described in the aforementioned document EP 1 736 509 is devoid of animation mechanism.
  • the main purpose of the invention is to propose a timepiece provided with both an animation mechanism and a striking mechanism and which allows the user to choose the animation function plus ringing or only the function animation.
  • the user of a timepiece according to the invention can operate the animation mechanism several times in succession quickly, without turning on the striking mechanism and without having to wait for the ringing cycle to be done before operating the animation mechanism again. If the user wishes to operate the two mechanisms, he can do it simply by acting on the stroke limiter.
  • One embodiment of a wristwatch according to the invention is schematically represented on the Figures 1 to 4 .
  • This wristwatch comprises known and not shown elements which are, in particular, a case with a caseband which delimits an internal chamber in which are housed a watch movement, an animation mechanism and a striking mechanism.
  • the constitution of these mechanisms is well known to those skilled in the art and therefore does not need to be described here. Only a rack 3 to operate these mechanisms is represented on the Figures 2 to 4 .
  • the wristwatch according to the invention comprises an actuator or bolt 1, intended to be manipulated from outside the casing by the user.
  • This bolt 1 has an elongated shape and is designed to slide along a portion of the periphery of the middle part. Its displacement, represented by the arrow D on the figure 1 , is rectilinear because the corresponding case side is rectilinear.
  • the bolt would have a curved shape and move in a circular path.
  • a connecting piece 2 provided to move in a suitable groove arranged in the middle.
  • An end face 11 of the connecting piece 2 opposite the end 10 of the bolt 1 is in contact with a piston 5 in the form of a full-bent cylinder extending in an arc of a circle along the periphery of the middle part of the housing.
  • the piston 5 is designed to slide in a groove located in the periphery of the caseband and is held by a first plate 6 provided with a hole through which it passes and a second plate 7 also provided with a hole that the piston 5 passes through. .
  • the first and second plates 6 and 7 are fixed in a known manner to the middle part.
  • An upstream direction can be defined as the one towards which the piston 5 is directed when the spring 9 expands and a downstream direction as being towards which the piston 5 is directed when the spring 9 is compressed.
  • An oblong opening is provided in the middle of the housing to allow the trigger rod 13 to move.
  • the contact between the trigger rod 13 and the rack 3 takes place at the face furthest downstream of the trigger rod 13.
  • the arrangement of the animation mechanism and the striking mechanism is provided so that the rack 3, during its rotation along the arrow E about its axis of rotation 12 caused by the trigger rod 13 driven by the displacement of the piston 5 downstream, moves from a first rest position A ( Fig. 2 ), at a position B where only the animation mechanism is actuated ( Fig. 3 ), then to a position C where the animation mechanism and the striking mechanism are actuated ( Fig. 4 ).
  • a first rest position A Fig. 2
  • a position B where only the animation mechanism is actuated
  • Fig. 4 the animation mechanism and the striking mechanism are actuated
  • the position B of the rack 3 is visible on the figure 3 . It is obtained when the bolt 1 is pushed along the arrow D and drives the piston 5 downstream against the force of the spring 9, until it comes into abutment against a stroke limiter 14.
  • This race limiter or rocker 14 has an elongate shape. At its end 16 opposite its end 17 facing the piston 5, it has a hole in which is introduced a limiter shaft 15 fixed to the middle of the watch case.
  • the stroke limiter 14 further comprises, approximately midway between its two ends 16 and 17, a second hole which is traversed by a rod axis 18 attached to a button rod 19. The axis of symmetry of this button rod 19 is substantially perpendicular to the limiter axis 15.
  • the end of the rod 19 located outside the housing is provided with a button 20.
  • the stroke limiter 14 is in its first position L1, called “stop” of the striking mechanism, in which it is in the path of the piston 5 and thus prevents last to move further downstream.
  • the stroke limiter 14 is in its second position L2, called “on” of the striking mechanism, it reaches when the user presses the button 20, thereby causing a push on the button rod 19, a rotation of the stroke limiter 14 around its limiter axis 15 and a displacement of its end 17 towards the inside of the housing, possible thanks to a suitable opening in the middle of the housing. It follows that the end 17 releases the trajectory of the piston 5, which can continue its course further downstream.
  • the operation of the timepiece can therefore be summarized as follows.
  • the user wishes to operate only the animation mechanism, it puts or verifies that the stroke limiter 14 is in its first position L1, that is to say that represented on the figures 2 and 3 by the location of the end 17 of the stroke limiter 14.
  • the bolt 1 Before the user pushes the bolt 1, it is then in the situation shown on the figure 2 , the bolt 1 being in its rest position P1 represented by the location of the end face 11 of the connecting piece 2.
  • the user arms the animation mechanism by pushing the bolt 1 in the direction of the arrow D.
  • the bolt 1 then pushes the piston 5 downstream.
  • the spring 9 is pushed by the ring 8 and the trigger rod 13 integral with the piston 5 drives the rack 3 in rotation in the opposite direction of the hands of the wristwatch, about its axis 12, from its position A rest at its position B, thus arming the animation mechanism.
  • the piston 5 abuts against the end 17 of the stroke limiter 14, which prevents the passage of the rack 3 in position C.
  • This situation is represented on the figure 3 , the bolt 1 being in its second position P2.
  • the animation is started and when the user releases the bolt 1, the latter, under the force of the spring 9, returns to its rest position P1.
  • the user wishes to actuate the striking mechanism he pushes the button 20 towards the inside of the housing, which brings the limit switch 14 to the operating position L2.
