Definitions

• the present invention relates to the field of watchmaking and more particularly to an indicator of the power reserve of a mechanical or automatic timepiece.
• the indicator member of the power reserve is secured to a wheel meshing with a differential gear wheel engaged with the barrel and the ratchet of the watch movement.
• EP1922591 proposes a clock mechanism for optionally displaying an indication in a window, the indication being chosen in particular from the calendar, the week, the year and the power reserve.
• the object of the present invention is to propose another way of indicating the power reserve in an original way.
• this object is achieved through a watch movement of a mechanical or automatic timepiece comprising a power reserve indicator device which is configured so as to indicate the power reserve on demand.
• the device comprises means for producing an acoustic signal which indicates the magnitude of the power reserve when said means are actuated.
• FIG. 1 represents a view from above of the indicator device of the power reserve according to the invention
• Figure 2 shows a bottom view indicating device of the power reserve according to the invention.
• the watch movement comprises according to Figure 1, a rocker 1 arranged to pivot on a pin (not shown) when actuated.
• This rocker 1 has an arm 2 which, when the movement is incorporated in a wristwatch, out of the middle of the box and fits into a lock (not shown) which is arranged to slide around the periphery of the box. 25 ° maximum.
• the rocker 1 has on part of its outline a rack 3 engaged with a rack pinion 4 fixed to a square of the shaft 5 of a barrel of ring 6 having a spiral (not shown), one of which other of its ends are respectively connected to the shaft 5 and to the wall of the drum of the striking barrel 6.
• the latter carries on its upper edge a ratchet ring 7 integral with the shaft 5.
• the ratchet 7 has a plurality of teeth, each tooth being arranged to actuate a hammer 8 by means of a lift 9 so that the hammer 8 strikes a stamp 10.
• a ringing wheel 11 is fixed to the shaft 5 of the ringing barrel 6 so that it only turns when the ringing barrel 6 disarms.
• the ringing wheel 11 is recessed and has on its inner circumference a toothing with wolf teeth which cooperates with two pawls with beak 12.
• This ringing wheel 11 also meshes with a multiplier gear train 13 which is engaged with a centrifugal type speed regulator 14 to slow down the disarming speed of the ringer barrel 6 to increase the time between each hammer stroke 8 on the stamp 10.
• the rocker 1 further comprises a probe 15 arranged to abut against a snail 16.
• the latter is secured to a star 17, which is driven by a wheel 18 engraining with a gear wheel 19 in mesh with barrel 20 and kinematically connected to ratchet 21 of the watch movement.
• the star 17 is indexed on the snail 16 and has twelve teeth.
• a jumper 22 acts on the toothing of the star 17 in order to position the snail 16 always in a satisfactory position.
• the entrainment of the limaçon 16 by the wheel 18 is made so as not to damage or prevent the mechanism from operating when the star 17 jumps from a tooth.
• the travel of the rack 3 corresponds to the power reserve since the probe 15 is arranged to abut against the limaçon 16 of the power reserve.
• the rack 3 rotates the rack pinion 4, in order to accumulate energy in the ringing barrel 6 and to position the ringing ratchet 7 so that a number of teeth representative of the power reserve is in position. upstream of lift 9.
• the ringing barrel 6 drives through its shaft the ringing wheel 11, the speed of rotation is regulated by speed controller 14 ( Figure 2).
• the striking ratchet 7, which is integral with the shaft of the ringer barrel 6, is rotated in order to actuate the lifting 9 to the passage of each of the teeth, so that said lifting 9 in turn actuates the hammer 8 for this one strikes on the stamp 10 a number of coup representative of the power reserve.
• the movement incorporating the aforementioned device has a power reserve of 108 hours.
• the reduction ratios of the gear train have been determined so that the wheel 18 rotates 360 ° while the barrel 20 is unwound by making ten turns.
• the star 17 is driven twelve steps in 108 hours and therefore a step every nine hours.
• the hammer 8 strikes the stamp 10 twelve times when the power reserve indicator device is actuated and it remains between 99 hours and 108 hours of power reserve, eleven times when it remains between 90 and 99 hours of power reserve, ten times when there is between 81 and 90 hours of power reserve, and so on until device strikes once the stamp to indicate a power reserve between 0 and 9 hours.
• the number of hits struck by the hammer on the stamp when the device is actuated may be different from the aforementioned configuration.
• the device is adapted so that the hammer strikes on the stamp one shot per day of remaining power reserve.
