Definitions

  • the present invention relates to an electronic watch which may or may not have a central seconds hand.
  • the present invention relates to a watch whose cog part of the movement is provided in such a way that it can easily be mounted with a seconds hand in the center or without this hand.
  • the invention relates to a watch in which the major part of the train of the movement is common for the two mounting versions and, in particular the plates, and only a limited number of mobiles must be added to obtain a watch with a seconds hand in the center or without this hand.
  • the watch according to the invention comprises for its two versions a motor, a frame, a first mobile mounted to pivot in the frame and driven by the motor, an hour mobile carrying the hour hand and a wheel of the hours, a coaxial hour carriageway carrying the minute hand and consisting of a minute pinion and a minute wheel; and a timer connecting the hour wheel to the minute pinion.
  • the first mobile consists of one. shaft provided with a bearing arranged in the plane of the minute wheel and a wheel receiving the movement of the engine.
  • the watch further comprises a guide tube open at its two ends and integral with the frame, the barrel wheel and the roadway being pivotally mounted on this tube, means integral with the frame for defining with the tube a first pivot axis combined with the referral axis, means integral with the frame to define a second pivot axis parallel to the referral axis, and means for kinematically connecting the first mobile and the minute wheel.
  • the kinematic connection means consist of a driven wheel on the reach of the first mobile and meshing with the minute wheel.
  • these same kinematic connection means consist of a second mobile comprising a second hand shaft mounted in the guide tube and the means defining the pivot axis, a wheel, for meshing with the wheel of the first mobile, and a pinion.
  • These means further comprise a third mobile, pivotally mounted in the means for defining the second pivot axis and comprising a pinion meshing with the minute wheel and a wheel meshing with the pinion of the second mobile.
  • the watch in its two versions has a large number of common parts and, in particular, the frame, that is to say all the bridges and plate, is strictly identical in both versions. Furthermore, the majority of mobiles are also common. Finally, in both versions, all the elements necessary for mounting additional mobiles are provided in the common areas. These means consist respectively in the bearing provided on the first mobile and in bores drilled in the frame or bearings mounted in the frame to define the first and second pivot axes.
  • the watch comprises a stepping motor 2 comprising a rotor 4.
  • the rotor consists essentially of a permanent magnet 4a and a pinion 4b.
  • the motor is pivotally mounted in the frame by means of bearings or the like, referenced 5. These bearings 5 are respectively formed in a bridge 6 and in a plate or base plate 8.
  • the motor 2 further comprises, of course, a stator which has not been shown in the figure.
  • a motor control circuit makes it possible to send control pulses to the stator coil which determine, in particular, the rate of rotation of the motor.
  • the watch then comprises a mobile transmission 10, constituted by a wheel 10a which meshes with the pinion 4b of the rotor and a pinion 10b.
  • This mobile 10 is pivotally mounted by means of bearings or the like, references 12 and formed respectively in the bridge 6 and the plate 8.
  • the watch then comprises a first mobile 14 comprising a wheel 14a.
  • This first mobile 14 of course also includes a shaft 14c provided with a cylindrical seat I4b, clearly separated from the wheel 14a.
  • the shaft which ends with two pivots engaged in bores or bearings 16. formed respectively in the deck 5 and the plate 8.
  • the watch also comprises a structure defining the referral axes, the referral axis being identified by the axis XX '.
  • This assembly firstly comprises a guide tube 18 open at these two ends and which is driven into a part of the frame referenced 20.
  • This tube 18 externally guides a minute mobile 22 which conventionally comprises, in addition to the tube 22a to l end of which is mounted the minute hand, a minute wheel 22b and a minute pinion 22c.
  • a 24 hour mobile On the outer face of the mobile 22 is mounted a 24 hour mobile which includes the hour wheel 24a and the barrel 24b at the end of which is mounted the hour hand.
  • This switch assembly is completed by a bore forming a bearing 26 which is formed in the bridge 6 and which is centered on the extension of the switch axis XX '.
  • the bore or bearing 26 and the tube 18 thus define a first pivot axis coincident with the referral axis XX '.
  • the watch also includes two bores forming bearings, referenced respectively 30 and 30 ′, which define a second pivot axis YY ′, offset with respect to the axis XX ′ and parallel to it.
  • this element of cog is particularly simple since it consists of a toothed wheel 32 which is driven onto the cylindrical bearing surface 14b of the mobile 14. This toothed wheel 32 meshes with the minute wheel 22b.
  • the wheel 32 has a primitive 0 Dl and the bearing 14b is arranged in the same plane orthogonal to the axis XX 'as the wheel 32.
  • the additional elements for producing the kinematic connection means in the case of a watch with a second in the center.
  • the first mobile 14 no longer has a wheel mounted on its cylindrical bearing 14b.
  • the means which make it possible to kinematically connect the first mobile 14 to the minute wheel 22b and which, moreover, also make it possible to drive the seconds axis are constituted by two additional mobile respectively referenced 34 and 36. From a point of general view the mobile 34 is the second mobile and it allows the driving of the second hand and the mobile 36 is a reduction mobile which allows to transmit the movement from the seconds mobile 34 to the minutes mobile 22 with the desired reduction.
  • the first additional mobile 34 comprises a shaft 34a, a seconds wheel 34b and a seconds gear 34c.
  • the shaft 34a is guided by the hollow tube 18 and by the engagement of the pivot 34d in the bore forming a bearing 26, formed in the bridge 6.
  • the seconds wheel 34b meshes with the wheel 14a of the first mobile 14 which in this case has no multiplier function.
  • the second additional mobile 36 is pivotally mounted by these two pivots 36a, 36'a in the bores 30 and 30 'formed in the plate 8 and the bridge 6.
  • the mobile 36 is pivotally mounted around the axis YY'.
  • the mobile 36 includes a wheel 36b which meshes with the second gear 34c of the second mobile 34. It also includes a pinion 36c which meshes with the minute wheel 22b.
  • a plug 40 for closing off the end of the road. In the case of the assembly of FIG. 2a, the plug 40 is put in place. In the case of the assembly of FIG. 2b, the plug 40 is removed to allow the passage of the seconds axis.
  • Figure 3 provides a better understanding of these dimensional relationships.
  • R 1 the pitch radius of the wheel 14a of the mobile 14 and R 2 the radius of the minute wheel 22b.
  • R 3 is called the pitch radius of the wheel 34b of the seconds wheel and R 4 is the radius of the wheel 32 which is mounted on the wheel 14 when there is no seconds wheel.
  • L the distance between the referral axis XX ′ and the pivot axis of the mobile 14 is called L.
  • the compatibility condition as to the position of the referral axis by relation to the pivot axis of the mobile e 14 so that the road wheel and the second mobile rotate at the appropriate speed is defined by the following relationships: and
  • the structure of the watch remains simple, it is possible to design a watch with a common part of the movement which brings together the majority of the elements of the train and to provide additional parts in reduced number which allow to mount this watch either with a seconds hand in the center or without this hand.
  • the invention therefore very precisely solves the problem posed under very acceptable economic conditions.
  • the common part certainly includes certain elements which would not be essential for one of the two embodiments, but these elements do not entail any complex machining. Indeed, these are holes in the bridge and the plate to define the axis YY 'or the machining of the cylindrical surface of the mobile 14.
