Definitions

the invention relates to a timepiece mechanism making it possible to memorize a time indication.
the invention also relates to a timepiece movement comprising such a mechanism for memorizing a time indication.
the invention also relates to a timepiece, in particular a watch, comprising such a movement or such a mechanism.
a second seconds hand commonly called split-seconds hand
split-seconds hand is superimposed on the chronograph second hand.
a first press on the split-seconds push button causes the split-seconds hand to stop while the second hand continues to run.
a second press on the split-seconds pusher brings the split-seconds hand back to the second hand.
Such a device is for example described in the work of B. Humbert entitled “The Chronograph” (chapter 13 ) or within the patent CH682201 .
the patent device CH682201 implements a control system, designed to drive a split-seconds wheel set, which consists of a rotating control cam, in particular a column wheel, and a pair of locking pliers.
the split-seconds chronograph which allows memorization of the second and the minute of a measured time.
the split-seconds memory capacity is no longer limited to sixty seconds but extended to the number of minutes displayed by the chronograph minute counter, thirty minutes in this case.
This device implements a split-seconds mobile whose particularity is to be actuated by the same column wheel as that actuating the split-seconds mobile.
the object of the invention is to provide a clockwork mechanism making it possible to remedy the drawbacks mentioned above and to improve the clockwork mechanisms known from the prior art.
the invention proposes a watch mechanism and a watch movement that is simple and reliable to display a memorized time to the nearest second, or even to a fraction of a second.
a timepiece 1 An embodiment of a timepiece 1 according to the invention is described below with reference to the figures 1 to 3 .
storage elements H', M', S', in particular additional hands, making it possible to indicate or display stored hours, stored minutes and stored seconds are attached to conventional H, M, S indication or display members, in particular conventional H, M, S hands.
the timepiece thus makes it possible to memorize a time to the nearest second while indicating the current time . It makes it possible in particular to display a time to the nearest second in a time range extending over several hours, in particular 12 hours, or even 24 hours.
the timepiece is for example a watch, in particular a wristwatch.
the timepiece comprises a timepiece movement 2.
the timepiece movement 2 itself comprises a timepiece mechanism 3 which is described in detail below.
This horological mechanism 3 comprises, for example, display members H, M, S, H', M', S' making it possible to indicate or display the current hours, minutes, seconds, even fractions of a second and indicate or display the stored hours, minutes, seconds, even fractions of a second.
the mechanism may for example comprise a member for indicating the current fractions of seconds and/or a member for indicating the stored fractions of seconds.
These indication members can for example be implemented by jumping seconds mechanisms. Subsequently, for simplicity, only hours, minutes and seconds display members are considered and no fractional seconds display member.
the members H, M, S for displaying the current hours, minutes and seconds and the members H', M', S' for displaying the stored hours, minutes and seconds indicate the current time.
the members H′, M′, S′ indicate stored time information.
the members H', M', S' for displaying the stored hours, minutes and seconds and the members H, M, S for displaying the current hours, minutes and seconds are thus again synchronized.
the members H', M', S' for displaying the stored hours, minutes and seconds and the members H, M, S for displaying the current hours, minutes and seconds therefore display the same indications.
the mechanism comprises a first device MEM1 for memorizing seconds, or even for memorizing fractions of a second and at least a second device MEM2 for memorizing minutes and/or hours.
the first storage device MEM1 further comprises a first storage mobile M1 provided with a first storage element MC1 in direct and permanent engagement with an element 12 of a gear train 11, 12, 13, 14, 15 for finishing the movement watchmaker or a first element of memorization fixed to an element of a going train of the watch movement.
the first storage element is in direct and permanent connection with the element 12 of the going train of the watch movement.
the mechanism may also include a member S for displaying seconds and/or fractions of seconds
the first storage device MEM1 forms an interface between the going train or the finishing chain and the member S' for displaying the stored seconds, in particular between a seconds wheel 12 and the member S' for displaying the seconds stored.
the going train may comprise a barrel 15, for example a center wheel 14, for example an average wheel 13, a seconds wheel 12 and an escapement wheel 11.
the going train may have, from the barrel to the oscillator, a completely conventional structure.
the going train may comprise several barrels, and more than three mobiles so as to kinematically link the barrel or barrels and the escape wheel.
the storage mobile M1 comprises a pinion M1a on which is mounted or fixed the first storage element MC1 comprising for example a cam MC10, in particular a heart-shaped cam.
This pinion M1a can be continuously meshed with the pinion 1a of the seconds wheel set 12.
the memorization wheel set M1 comprises a wheel M1a' which meshes with the wheel 1a' of the wheel set 12' on which is mounted or of which the member S′ for indicating the stored seconds, in particular on which the storage hand S′ is driven.
This wheel M1a' is also integral with a plate MP1 on which an elastic return lever ML1 pivots.
the wheel M1a' and the plate MP1 are advantageously fixed one on the other.
the wheel 1a' and the display member S' of the stored seconds are connected by a shaft passing right through the frame B of the movement 2 of the timepiece 1, as shown in figure 5 .
a control cam C1 in particular a column wheel, is positioned so that a locking device B1 of the plate MP1 is deactivated.
the blocking device has no grip on the plate MP1 and therefore on the mobile storage M1.
the action of the return lever ML1 on the cam MC10 causes the synchronous rotation of the plate MP1 and the cam MC10 and therefore an identical display for the seconds member and the memorized seconds member.
Mechanism 3 includes cam C1 for controlling the first storage device.
the blocking device B1 comprises at least one lever or clamp, preferably two levers or clamps P1 and P10, and a spring R1.
the elements are arranged so that the spring tends to pull the clamps away from the MP1 plate and therefore does not immobilize the MP1 plate (as shown in figure 8 ).
the columns of the column wheel and a feeler LP1 are arranged to cause the contact of the clamps P1 and P10 against the plate MP1 when the feeler LP1 is resting on a column of the wheel (as shown in figure 9 ).
the display and memorization mechanism comprises the blocking device B1.
control cam C1 is in the form of a column wheel which is angularly indexed by a spring R.
This is for example provided with a binary profile C1a which consists of columns and hollows.
the feeler LP1 of the gripper P1 is located opposite one of the recesses of the profile C1a so that the spring R1 positions the grippers P1 and P10 out of reach of the plate MP1 on which the elastic return lever ML1 pivots which is intended to cooperate with the MC10 cam.
the control cam C1 can also be provided with a ratchet toothing C1b which is provided to be actuated and driven with an angular pitch by a lever L under the effect of a control member O.
a pressure on the latter induces the rotation of the control cam C1 so that one of the columns of the profile C1a drives the clamps P1, P10 against the spring R1 so that they can immobilize the plate MP1 in rotation of mobile M1.
the lever ML1 is locked in a well-defined angular position of the plate MP1, while the cam MC10 continues to rotate. This situation results in immobilization of the stored seconds display member S′, while the seconds display member S continues its course.
a new action on the control member O positions the control cam C1 in a configuration similar to that of the figure 9 ; the head of the lever ML1, under the effect of its elastic return element, is then repositioned against the shoulders, or the recesses, or the flat, of the cam MC10.
the mechanism 3 includes the control member O. This control member makes it possible to act on the control cams C1, C2.
the second storage device MEM2 provides an interface between the hours and minutes display units H, M and the stored hours and minutes display units H' and M'.
the second storage device comprises, in addition to the second mobile M2, an auxiliary timer linking the member H' for displaying the stored hours and the member M' for displaying the stored minutes, in particular in mesh, with the second mobile M2 for storing.
the second storage mobile M2 comprises a wheel M2a on which is mounted or fixed the second storage element comprising for example a cam MC20, in particular a heart-shaped cam.
This wheel M2a can be continuously meshed with an hour wheel 162 which carries the hour display member H.
the storage mobile M2 comprises a wheel M2a' which meshes with a wheel 162a' secured to the wheel 162' which carries the member H' for displaying the stored hours.
This wheel M2a' is also integral with a plate MP2 on which an elastic return lever ML2 pivots.
the wheel M2a' and the plate MP2 are advantageously fixed one on the other.
the second storage device is similar to the first storage device.
the members H and M for displaying the hours and minutes are linked to the members H' and M' for displaying the hours and minutes stored by means of the second storage mobile M2.
the second memory mobile M2 is arranged on the side of the frame of the movement opposite to that on which the first memory mobile M1 is arranged as shown in the figure 5 , 11 , 12 .
the structure of the second storage mobile M2 is similar to that of the mobile of M1.
the second mobile M2 comprises a wheel M2a on which is mounted a cam MC20, in particular a heart-shaped cam.
This wheel M2a is in mesh, in particular continuously in mesh, with an hour wheel 162 on which the member H is mounted. hour display, in particular on which an hour hand H is driven.
the second mobile M2 also comprises a wheel M2a' which drives the storage hour wheel 162' by means of a wheel plate 162a' which is mounted on it.
the kinematic connection between the memorized hours wheel 162', on which the memorized hours display member is mounted, in particular on which a hand H' is driven, and the roadway 164', integral with the display member memorized minutes M', is carried out, for its part, via the auxiliary timer 16', the structure of which is identical to that of the timer 16.
a blocking device B2 is dedicated to the memory mobile M2.
Blocking device B2 is similar to blocking device B1.
the blocking device B2 comprises at least one lever or clamp, preferably two levers or clamps P2 and P20 and a spring R2.
This blocking device is also controlled by a control cam C2, for example a column wheel.
the display and memorization mechanism comprises the blocking device B2.
Mechanism 3 includes cam C2 for controlling the second storage device.
the control cam C2 has the particularity of being integral in rotation of the control cam C1 by means of a shaft A which passes right through the frame B of the movement 2 of the timepiece 1, as shown in figure 14 .
a geometry GA of the shaft A is provided to cooperate with a geometry GC2 complementary or substantially complementary to the control cam C2 in order to facilitate the angular indexing of the control cam C2 relative to the cam of command C1.
the first control cam C1 and the second control cam C2 are connected by a shaft A.
the control cam C2 is positioned so that the blocking device B2 has no grip on the mobile storage M2. More specifically, one end of an arm LP2 of the clamp P2 is located opposite one of the recesses of the profile C2a so that the spring R2 positions the clamps P2 and P20 out of reach of the plate MP2.
the head of the return lever ML2 is in continuous support against the shoulders, or the hollow, or the flat formed on the profile of the cam MC20, which results in a synchronization of the play of the organs H 'and M' for displaying the stored hours and minutes and the set of organs H and M for displaying the hours and minutes.
the profiles C1a, C2a of the respective cams C1, C2 can be shaped differently if the blocking devices B1, B2 have distinct operating modes.
the cams C1 and C2 are defined so as to synchronize the blocking devices B1, B2 with a view to synchronizing the stopping of the organs H', M' and S' for displaying the hours, minutes and memorized seconds.
the first storage mobile M1 is in direct and permanent engagement with the mobile for the seconds of the going train.
This storage mobile is controlled by the first blocking device B1.
the second storage mobile M2 allows the storage of hours and/or minutes. It is in direct contact with the basic movement timer. This storage mobile is controlled by at least one second blocking device B2.
control cams C1, C2 are provided to drive each of the blocking devices B1, B2. They are actuated via the control member O which transmits the actions that the user exerts on the display and memorization mechanism 3, on the movement 2 or on the timepiece 1.
the control cams C1, C2 are movable in rotation. They are shaped to be arranged on either side of the frame B of the timepiece 1 so as to drive the at least two blocking devices B1, B2.
the seconds mobile 12 is for example arranged on a first side of the frame B of the movement, while the timer is conventionally arranged on the other side of the frame of the movement as shown in the figure 11 .
the mechanism 3 has a median plane P3 parallel to the plane PB of the frame B of the movement.
the median plane P3 is substantially perpendicular to the shaft A and to the mobile 12' and divides the space into two parts of the same volume in which the mechanism 3 is entirely contained.
the plane PB of the frame separates the plate from the movement into a first part and a second part of substantially equal dimensions.
the first storage device MEM1, in particular the storage mobile M1 and/or the first storage element MC1 and/or the tray MP1 is located in the first part.
the second storage device MEM2, in particular the storage mobile M2 and/or the first storage element MC2 and/or the tray MP2 is located in the second part.
the display and memorization mechanism comprises members for displaying the time and for memorizing a moment preferably lying within a range of 12 hours, or even 24 hours.
the time display members and the storage members move at the same rate over the same time range.
the time display hands and the memorization hands indicate information on two distinct time ranges.
the mechanism for each of the time or time information, hours and/or minutes and/or seconds, has the specificity of selectively indicating the stored information or the current information by the same display device under the actuation of a single control device.
a mechanism can for example be useful for marking the start time of an event and indicating its end time to the nearest second.
a positioning of display members in one or more random positions or defined once and for all, that is to say in one or more positions that cannot be defined or can be modified by the user, such as can be found in mechanisms display on demand, does not constitute a storage within the meaning of the invention.
direct drive we mean any kinematic connection devoid of a clutch device.
the connection is therefore permanent.
one or more intermediate elements may be arranged between the seconds wheel and the memorization wheel set.
