Description
Technical Field
The invention relates to a timepiece movement comprising:
a jump display mechanism, the jump display mechanism comprising:
a display wheel intended to drive display elements by jumping according to a first time period;
an actuating lever arranged to act on the display wheel according to the first time period and advance the display wheel by at least one pitch of bounce;
a resilient element arranged to apply a force to the actuating lever tending to move the actuating lever towards the display wheel;
a first control element driven by a first wheel of the timepiece movement according to a first time period to guide the actuating lever to a first standby position and to charge the elastic element, the first control element also being arranged to disengage the actuating lever after it has been set in its standby position and to allow the actuating lever to act on the display wheel under the action effect of the elastic element.
Background
A jump display mechanism satisfying the above characteristics is known from the prior art, more specifically, but not limitatively, providing a date display.
These mechanisms must comply with a certain number of constraints when they are implemented, in particular the following two: on the one hand, the first control element must be arranged to transmit sufficient energy (in the form of torque for the majority of the time) to allow the elastic element to be charged, while disturbing the going train of the timepiece movement as little as possible, and on the other hand, it is desirable for the mechanism to be arranged so that satisfactory precision is achieved with respect to the moment at which the display element jumps. It is also generally desirable that the bouncing of the display element occurs as quickly as possible, i.e. almost instantaneously.
In the case of a date display mechanism, the display wheel is typically driven by twenty-four hour wheels, which introduces an uncertainty as to the minutes at which the jump actually occurs.
Patent application EP 1586961 a2 provides an example of a jumping display mechanism for dates that satisfies the characteristics set forth above. More specifically, this mechanism comprises a cam rotating under the action of a twenty-four hour wheel to energize a primary elastic element via an energy storage lever whose feeler-spindle bears on the periphery of the cam. The cam is substantially in the shape of a deformed heart, the edge of which is rotated during operation in the direction of rotation thereof from its hollow at a position of about 2/3 a. The charging of the main elastic element therefore takes place within about sixteen hours, so as to limit the disturbances caused in the going train. The connection between the cam and the twenty-four hour wheel is provided by fingers supported by the wheel and engaged in slots in the form of circular portions arranged in the cam. When the trigger-mandrel of the charging lever crosses the edge of the heart-shaped cam, the action of the main elastic element on the charging lever drives the cam in an abrupt rotation with respect to the twenty-four hour wheel, which may be caused by the movement of the finger in the slit. The additional cam fixed to the heart-shaped cam then acts on the date lever, lifting it and then rapidly releasing it between the moment when the hook-arbour crosses the edge of the heart and the moment when it is located opposite the hollow of the heart. When the date lever is released, it falls on a portion of small radius of the additional cam under the action of the auxiliary elastic element and it acts on the display wheel to cause the date display element to jump by one pitch.
Although the mechanism described in this application makes it possible to ensure a rapid jump of the date display element, there is still an uncertainty of a few minutes of the moment at which the jump actually occurs, since the latter is indirectly controlled by the twenty-four hour wheel.
In an attempt to solve this problem, the invention relates to a mechanism of the type mentioned above, further comprising a blocking element arranged to temporarily lock the actuating lever when the first control element is in its standby position, and thereafter to release the actuating lever, so that the actuating lever can actuate the display wheel at a more precise and almost instantaneously defined moment.
Patent application EP 1801671 a1 proposes another example configuration of a mechanism for displaying the date so as to be able to perform a quick jump of the date display element by implementing a blocking element.
In practice, such a mechanism comprises a twenty-four hour wheel carrying a worm cam, the actuation lever remaining under the action effect of the elastic element. Since the cam is rotated until its point with the highest radius is located opposite the actuating lever, it is possible to position the actuating lever in the standby position and at the same time charge its elastic element. When the cam continues to rotate to a point where it has a minimum radius, which is disposed opposite the actuating lever, the actuating lever remains locked in the standby position by pivoting the locking pawl. Shortly thereafter, the locking pawl is deactivated by the action of a resilient finger supported by a twenty-three-four hour wheel.
Here, however, the release of the jump of the display element is commanded again by the movement of the twenty-four hour wheel, which only partially enables the problems associated with the uncertainty as to the actual moment of the jump to be solved.
Thus, there is still a need to define a definition of the configuration for the jump display mechanism, which will enable a better control of the instant of the actual jump than in the known configurations.
Disclosure of Invention
A main object of the present invention is to propose a jump display mechanism of the type mentioned above, which has alternative configurations to those described above, but with limited complexity, so that the display wheel will in fact have a reduced uncertainty as to the moment of jump with reference to the mechanisms already known.
To this end, the invention more particularly relates to a timepiece movement that satisfies the above-mentioned characteristics, said timepiece movement satisfying the above-mentioned characteristics, characterized in that,
the display mechanism comprises a second control element arranged to deactivate the blocking element and to release the actuating lever when the actuating lever is in its standby position, and
the second control element is driven by a second wheel of the timepiece movement to deactivate the blocking element according to a second time period shorter than the first time period.
By "deactivating said blocking element" is meant that the second control element acts on the blocking element such that the blocking element changes from the locked state of the actuating lever to the disabled state, i.e. the state in which it no longer acts on the actuating lever, thereby locking it in the standby position. The actuating lever is then free to actuate the display wheel.
Due to these features, the moment at which the jump actually occurs can be defined with greater precision than in the case of the previous construction, since the control element responsible for releasing the jump has a faster movement than the control element responsible for placing the actuating lever in its standby position.
Thus, for example, if the display mechanism is intended to display a date, it may be provided to drive the second control element for a period of time of one hour, for example, which makes it possible to reduce the uncertainty about the moment of release from a few minutes to a few seconds.
Preferably, there may also be provided:
the blocking element comprises a locking element having a locking surface intended to cooperate with a stop surface of the actuating lever to lock the actuating lever when the actuating lever is in its standby position, and
the display mechanism comprises an additional resilient element arranged to act on the locking element and to tend to set the locking element in a locking position, the second control element being arranged to move the locking element in accordance with the second period of time such that the locking element moves out of its locking position.
According to a first alternative embodiment, it is possible to provide: the locking element is movable according to a translational movement to occupy or leave its locking position.
According to a second alternative embodiment, it is possible to provide: the locking element is movable in accordance with a rotational movement to occupy or leave its locking position. The locking element may comprise, inter alia, a locking bar.
In this case, it is also possible to provide:
the locking lever having an arm that is actuatable by the second control element such that the locking surface frees the actuating lever,
the second control element comprises a rotator wheel having actuating fingers arranged to cooperate with the arm (34) once per full revolution of the rotator wheel; and is
The arm carries a bar spring arranged such that:
the actuating finger acting on the arm by means of the strip spring in a first direction of rotation of the rotary wheel; and is
When the rotary wheel is rotated in a rotational direction opposite to the first rotational direction, the actuation finger acts on the strip spring to cause the strip spring to undergo a temporary elastic deformation without driving the arm.
Thanks to these features, the second control element must transmit only a limited torque to deactivate the blocking element, which preferably avoids any interference with the going train of the timepiece movement. Furthermore, the display mechanism is protected during the setting manipulation.
Advantageously, it is possible to provide:
the first control element has a cam with a periphery that is substantially volute shaped, the cam being rotationally fixed with a twenty-four hour wheel; and is
The radius of the periphery of the cam varies substantially continuously from a minimum radius portion towards a maximum radius portion, the minimum radius portion and the maximum radius portion being interconnected by a large slope portion that ensures disengagement of the cam when the large slope portion is opposite the actuating lever.
In this case, it is advantageously possible to provide: the maximum radius portion is located on an end portion of the periphery of the cam defined by a small projection.
In general, there may be provided:
the actuation lever comprises a retractable actuation beak intended to actuate the display wheel; and/or
The value of the first time period is an integer multiple of the value of the second time period; and/or
The first period of time has a value substantially equal to twenty-four hours such that the display wheel can drive the display element to indicate information relating to the date.
In the latter case, it may advantageously be provided that the value of said second period of time is substantially equal to or less than one hour.
In general, there may also be provided: the second wheel rotates discontinuously, preferably in jumps, according to the second time period.
The invention also concerns a timepiece equipped with a timepiece movement that satisfies the above characteristics.
Drawings
Further characteristics and advantages of the invention will appear more clearly on reading the following detailed description of a preferred embodiment, provided as a non-limiting example, with reference to the accompanying drawings, and in which fig. 1 to 4 show identical simplified plan views of a portion of a timepiece movement according to the invention, including a jump display mechanism illustrated in four configurations respectively spaced apart over time, to show its operation.
Detailed Description
Fig. 1 to 4 show identical simplified plan views of a part of a timepiece movement according to a preferred embodiment of the invention, including a jump display mechanism. Fig. 1 to 4 show respective arrangements spaced apart over time in order to describe the operation of the jumping mechanism.
The timepiece movement according to the invention comprises a conventional frame intended to support the components of the movement, which is not shown for greater clarity. The timepiece movement will not be described in detail, since some of its constituent elements are not illustrated and have no direct effect on the implementation of the invention.
In the presently preferred embodiment, the timepiece movement comprises, as a non-limiting example, a jumping display mechanism 1 for information such as the date.
The jumping display mechanism 1 may be implemented in a clock including a date display using a disk (alternatively, a big date form) or manually. The timepiece movement can be arranged to allow simple, annual, permanent or even popular dates to be displayed without directly affecting the realisation of the invention.
The display mechanism 1 has a display wheel 2, the display wheel 2 here presenting, by way of non-limiting illustration, a star-shaped form with seven asymmetric branches. Advantageously, the display wheel 2 can also have a gear (not shown) coaxial with the star and intended to drive a date display element (not shown), or alternatively the display wheel 2 can be intended to directly carry a display element for the date.
The display mechanism 1 according to the invention is pulsating, i.e. the display wheel 2 is intended to be driven by a pulsation, during which the display wheel 2 rotates one pitch at each pulsation. Of course, other alternatives are contemplated without departing from the scope of the invention.
Advantageously, jumpers (not shown) are provided to hold the display wheel 2 in its use position.
The display mechanism 1 also has an actuating lever 4, which actuating lever 4 can cooperate with the display wheel 2 in order to advance it by pitch.
For this purpose, actuating lever 4 is arranged to pivot by one end 6 thereof on a frame element of the timepiece movement.
The actuating lever 4 comprises a first arm carrying at its free end a retractable beak 8, the retractable beak 8 being intended to cooperate with the display wheel 2 so that it advances by one pitch of runout.
Furthermore, the actuating lever 4 has a second arm 10, the second arm 10 defining, at its free end, a feeler-spindle 12, the feeler-spindle 12 being arranged to cooperate with the periphery of the snail cam 14.
Finally, the actuating lever 4 has a third arm 16, the third arm 16 having in particular a sharp edge 18 at its free end, the function of which will be described later.
The cam 14 defines, together with the twenty-four hour wheel 20 to which it is fixed, a first control element of the jump display mechanism. Twenty-four hour wheel 20 is driven by a first driving wheel (not shown) (e.g. an hour wheel) of the timepiece movement according to a first twenty-four hour period via an intermediate wheel having a plurality of teeth adapted to provide the required reduction.
The periphery of the cam 14 has a short first minimum radius portion 22 followed by a continuously increasing radius until a maximum radius portion 24 is reached, defined by a slight projection of the continuity of its curvature. The minimum radius portion and the maximum radius portion are connected to each other by a large slope portion 26. By way of non-limiting illustration, the circumference of cam 14 between minimum radius portion 22 and maximum radius portion 24 here extends over an angle slightly greater than 360 degrees, with portion 26 having a slope greater than 90 degrees relative to the direction of portion 24.
It can thus be seen that, starting from the situation in which the feeler-spindle 12 is pressed against the minimum-radius portion 22, by rotation of the cam 14 in the anticlockwise direction, the pivoting of the actuating lever 4 is driven so that its feeler-spindle 12 is gradually moved away from the centre of the first control element.
A resilient element 27 (shown schematically in fig. 1) is provided to exert a force on the actuating rod 4 such that its touch hook-spindle 12 remains supported at all times on the periphery of the cam 14. The elastic element 27 may be made in the form of a separate component from the actuating rod 4 or, alternatively, it may be made in a single piece with the actuating rod 4, to simplify its construction, manufacture and assembly, without going beyond the scope of the present invention.
The more potential energy the elastic element 27 is charged with, the hook-mandrel 12 therefore cooperates with the point of the cam of greater radius.
Furthermore, the display mechanism 1 has a locking lever 28, the locking lever 28 being mounted on a frame element of the timepiece movement in such a way as to rotate with a shaft 30. Although the presently preferred embodiment of the illustrated invention provides a locking lever 28 that rotates about an axis 30, a corresponding locking function may also be achieved by effecting a translational movement of the locking element or according to any other suitable movement that is not simply a rotation, without departing from the scope of the invention.
The locking lever 28 has a first arm defining a locking surface 32 at its free end, the locking surface 32 being intended to cooperate with the sharp edge 18 of the actuating lever 4, the sharp edge 18 defining a stop surface, as will be explained later.
The locking lever 28 has a second actuating arm 34, the second actuating arm 34 being intended to cooperate with a second control element 36 of the display mechanism 1.
A resilient element (not visible) is arranged to apply a force to the locking lever 28 tending to keep it supported on the actuating lever 4, i.e. to rotate it in a clockwise rotational direction.
The second control element 36 has a gear wheel (not shown) carrying an actuating finger 38, the actuating finger 38 being arranged to actuate the second arm 34 of the locking lever 28 upon each complete rotation of the second control element 36 about itself.
According to the invention, provision is made for: the second control element 36 is driven by the second drive wheel of the timepiece movement to have a second time period shorter than the first time period of twenty-four hours of the first control element. Preferably, the value of the first time period may be an integer multiple of the value of the second time period. For example, it can be provided that the second control element 36 is driven continuously or discontinuously or even in a pulsating manner, so as to have a time period of approximately one hour or less. It is therefore possible to consider driving the second control element 36 from a cannon pinion or hour wheel (in this case, the multiplication ratio is equal to 1) to perform one revolution around itself in one hour.
Furthermore, advantageously, it is possible to provide for: the second arm 34 carries a strip spring 40, with which strip spring 40 the second arm 34 is actuated by means of the second control element 36. More specifically, as can be seen in the view of fig. 1, when the actuating finger 38 is rotated in a clockwise direction, one revolution thereof pushes the bar spring 40 once, so that the bar spring 40 causes the locking lever 28 to rotate. However, if the actuating finger 38 is rotated in the counterclockwise rotational direction, it applies pressure to the bar spring 40 such that the bar spring 40 temporarily elastically deforms to allow the actuating finger 38 to pass without driving the locking lever 28 to rotate.
Now, the operation of the display mechanism 1 which has been described above will be explained in conjunction with all fig. 1 to 4.
Starting from the configuration of fig. 4, when the feeler-spindle 12 is arranged to bear on the minimum-radius portion 22 of the cam 14 and the portion 22 is rotated by the rotation of the twenty-four hour wheel 20, the cam 14 rotates to present an increasingly larger radius to the feeler-spindle 12 until the configuration illustrated in fig. 1 is reached.
From the configuration of fig. 4 to the configuration of fig. 1, the charging state of the elastic element 27 increases while the actuating lever 4 is pivoted in the clockwise rotating direction.
At the same time, it can be seen that the stop surface 18 is close to the locking surface 32 of the locking lever 28 and the actuating finger 38 performs a full rotation, actuating the second arm 34 of the locking lever 28 at each pass (for the sake of simplifying fig. 2 to 4, the strip is no longer shown), without having an effect on the display wheel 2, since the only consequence of this action can be summarized as the first arm of the locking lever 28 moving reciprocally with respect to the actuating lever 4, without changing the position of the actuating lever 4.
Fig. 2 illustrates the configuration of the display mechanism 1 when the cam 14 continues its rotation until the maximum radius portion 24 is opposite the trigger hook-spindle 12 of the actuating rod 4.
The actuating lever 4 is then placed in the standby position with its edge 18 engaging the locking surface 32 of the locking lever 28 (by the locking lever 28 rotating under the action of its elastic element).
The actuating lever 4 is temporarily held in the standby position, while the second control element 36 continues its rotation in the clockwise direction of rotation until the actuating finger 38 comes into contact with the second arm 34 of the locking lever 28, as illustrated in fig. 3.
In the configuration illustrated in fig. 3, it can be seen that the cam 14 continues its travel and, due to the action of the locking lever 28, the feeler-spindle 12 is no longer arranged to bear on the periphery of the cam. The cam 14 is therefore disengaged from the actuating lever 4, but the actuating lever 4 remains suspended in the standby position under the effect of its cooperation with the locking lever 28.
At the same time, the actuating finger 38 exerts a pressure on the second arm 34 of the locking lever 28, thereby driving the second arm 34 to rotate in the counterclockwise rotational direction.
As a result, the locking surface 32 is free from the stop surface of the actuating lever 4, so that the actuating lever 4 is released, the actuating lever 4 falling onto the cam 14 under the action of its resilient element 27, can be released, as illustrated in fig. 4.
Upon lowering thereof, the actuating rod 4 in fact actuates the display wheel 2 in a clockwise direction of rotation by means of its retractable beak 8, driving the corresponding display element forward by one pitch.
The cycle already described above is then restarted, causing the display elements to advance one pitch every twenty-four hours.
Thanks to the features already described, an optimized jump display mechanism is obtained. On the one hand, the first control element allows the elastic element of the actuating lever to be slowly charged while driving with a high torque, but the forces that develop over time cause a minimum level of damage to the going train. On the other hand, the release of the actuating lever by the second control element, which achieves a reduced period of time, makes it possible to precisely define the moment of the actual jump, greatly contributing to the overall quality of the display mechanism. It is to be noted that the torque required to deactivate the blocking element (i.e. the locking lever 28 is actuated by the actuating finger 38) is very low, thereby still further limiting the risk of disturbances that the going train may experience.
Thus, a previously unheard of jump display mechanism is created, the operation of which is optimized due to the implementation of two complementary control elements.
The foregoing description is intended to describe one particular embodiment as a non-limiting illustration, and the invention is not limited to the implementation of certain specific features that have just been described (e.g., the shape of the cam 14 or the nature of the gear to which the cam 14 is secured). For example, a cam may be manufactured having a plurality of identical portions that are each activated in turn and each of the portions is activated for twenty-four hours. Then the first rotation period of the first control mechanism will be a multiple of twenty-four (the multiple corresponding to the number of identical portions of the cam). Furthermore, any other type of drive suitable for the second control element 36 may be provided, provided that the value of its time period is such that a good precision and definition of the instant of the actual run-out of the display wheel 2 (i.e. a precision of the order of a few seconds) can be guaranteed. Of course, the other components described and illustrated may take any other suitable form (in particular, the locking lever and the display wheel) without departing from the scope of the present invention. Furthermore, instead of bar spring 40, other means may be provided in order to protect display mechanism 1 from potentially incorrect operations, in particular during the setting of a timepiece movement, without going beyond the scope of the present invention.
In general, for example, in the context of a timer-type function, a jump display mechanism according to the present invention may also be implemented in conjunction with the display of other types of information (e.g., the display of jump hours or jump minutes), whether it relates to current or on-demand time information.
A person skilled in the art will not encounter any particular difficulty in adapting the disclosure to his own needs and in realising a timepiece movement that only partially satisfies the features described, including a jump display mechanism comprising two control elements driven according to different respective time periods, without going beyond the scope of the present invention.
