Definitions
- the present invention relates to a function selection system for a watch.
- the invention also relates to a watch mechanism comprising such a function selection system and a watch comprising such a mechanism.
- complicated watches include numerous functions including, for example, chronograph functions, alarm functions or display of the day of the week, date, month, year, moon phase, information according to which a year is a leap year or not, the display of several time zones in the case of so-called GMT (Greenwich Mean Time) watches.
- GMT Greenwich Mean Time
- each of said functions requires a correction and/or triggering device which requires an external control member (push button, correction rod or corrector for example) which is specific to it for its actuation.
- Multiplying the number of external control elements can quickly become cumbersome or even impractical and unsightly in a timepiece displaying a lot of information, particularly in a watch such as a pocket watch or a wristwatch in which the considerations of space are particularly limiting.
- increasing the number of push buttons and/or correctors inevitably increases costs and constraints, particularly to guarantee watertightness.
- Watch mechanisms comprising several display correction devices operable by means of the same control member are known.
- watches allowing both the day of the week and the date to be displayed and comprising a winding stem allowing the choice of correcting the display of the date or that of the day of the week.
- Some of them include a winding stem capable of taking several distinct axial positions, intermediate between the winding position (rest) and the time setting position (pulled), and allowing in one of these axial positions to correct the date and in another to correct the day of the week.
- Others include a winding stem allowing the date to be corrected by pivoting in one direction and the day of the week to be corrected by pivoting in the other direction.
- An aim of the present invention is to propose a system making it possible, in a watch comprising numerous functions to be controlled, to limit the number of external control members for controlling these functions.
- the invention proposes a function selection system for a watch comprising a frame carrying a movable member between n stable positions, n being an integer greater than or equal to 2, said movable member being intended to be moved from one position stable to another in relation to the frame by a movement communicated to the watch by its wearer, maintained in each of said stable positions by an elastic or magnetic restoring force and arranged so that it is capable of selecting a function according to the stable position which he occupies.
- the movement communicated to the watch by its wearer and capable of moving the movable member from one stable position to another is typically a voluntary movement causing an acceleration of the movable member or of a part of the controlling function selection system. the movement of the mobile member.
- the different functions among which the function selection takes place are typically chosen from chronograph functions (trigger, stop, reset), chime (trigger, stop) or display ( in particular correction) of the day of the week, the date, the month, the year, the moon phase, the information according to which a year is a leap year or not, the display of several time zones in the case so-called GMT (Greenwich Mean Time) watches.
- chronograph functions trigger, stop, reset
- chime trigger, stop
- display in particular correction of the day of the week, the date, the month, the year, the moon phase, the information according to which a year is a leap year or not
- GMT Greenwich Mean Time
- a watch mechanism comprising a function selection system according to the invention, it is possible to provide a single control member to control several different functions. The user is able to select, through the function selection system, the specific function on which the control unit acts.
- each movement communicated to the watch by its wearer and capable of generating a change in stable position of the movable member is typically applied in a direction having a main component in a predetermined direction and the movement of the member movable towards a stable position or another depends on the direction of said movement in said predetermined direction.
- the movable member is typically capable of moving between two extreme positions constituting two of said n stable positions under the effect of one or more successive movements communicated to the watch by its wearer.
- the function selection system comprises a rocker intended to pivot relative to the frame between two extreme positions constituting stable positions of the rocker.
- Each of said stable positions of the rocker is associated with a stable position of the mobile member.
- the pivoting amplitude of the rocker is typically delimited by stops which define said two extreme positions.
- the rocker is unbalanced in order to amplify said movements. It typically carries an element whose density is greater than its own, eccentric in relation to its center of rotation. Said element is preferably arranged on the end farthest from the center of rotation of the rocker.
- the rocker typically comprises an element, for example a pin or a tooth of a star, intended to be held in abutment against a first inclined plane of a jumper, respectively against a first face of an elastic blade, or against a second inclined plane of said jumper, respectively against a second face of said elastic blade.
- Said jumper or said elastic blade being fixed on the frame to define two distinct stable positions of the seesaw.
- the energy that the user must provide to cause acceleration allowing the seesaw to move from one stable position to another depends, among other things, on the stiffness of the spring of this jumper or this elastic blade as well as of its shape. This force can therefore be easily adjusted by playing on this criterion.
- the rocker is for example integral in rotation with a star positioned by a jumper or by an elastic blade, preferably a jumper, fixed on the frame.
- the function selection system comprises a connecting rod mounted to pivot around a fixed axis of rotation relative to the rocker.
- the connecting rod carries the movable member and is guided along a predetermined trajectory so as to bring the movable member into each of said n stable positions.
- the invention also relates to a watch mechanism comprising a function selection system as described above.
- a watch mechanism typically comprises a control member, accessible from outside the watch case, whose actuation by the wearer of the watch allows the mobile member to cooperate, depending on the stable position it occupies, with a separate trigger, to control the selected function.
- It is preferably a time zone mechanism comprising at least one function for incrementing the display of the hours of a time zone and a function for decrementing the display of the hours of said time zone, the function selection system allowing one or other of said functions to be selected.
- the invention relates to a watch, typically a wristwatch or a pocket watch, comprising such a watch mechanism.
- FIG 1 represents a watch mechanism 1 for a watch comprising a function selection system according to a first embodiment of the invention.
- THE figure 2 And 3 illustrate more precisely certain parts of this mechanism 1.
- An example of a watch 10 comprising such a watch mechanism 1 is illustrated in Figure 4 .
- This is a GMT watch allowing the display of two time zones, one intended for the display of local time called “local time” (hand 91) and the other for the display of the time of the place of residence known as “home time” (pointer 131).
- the hour mobile 11 is rotated at a rate of one revolution every twelve hours by the roadway 7 in a known manner.
- the second twelve hour wheel 11a is rotated via a mobile (not illustrated) comprising a wheel meshing with the roadway 7 and a timer pinion meshing with the second twelve hour wheel 11a.
- the third hour wheel 11b meshes with a time setting gear 12 which meshes with a twelve-hour “home time” wheel 13.
- the twelve-hour “home time” wheel 13 is, for its part, pivotally mounted on the barrel of the twelve hour “local time” wheel 9. It typically carries a hand 131 allowing the time of the place of residence to be displayed on the dial 14 of the watch 10.
- the third twelve-hour wheel 11b also meshes with the 24-hour “home time” wheel 3 and the 24-hour “local time” wheel 2 meshes with the 12-hour “local time” wheel 9.
- the basic working principle of mechanism 1 is as follows. Under the influence of drive wheel 8, hour mobile 11 rotates at a rate of one revolution every 12 hours. It drives, via its third hour wheel 11b, the 24-hour “home time” wheel 3 at a rate of one revolution per 24 hours. This causes the 24-hour “local time” wheel 2 to rotate at the same rate (via the elastic connection 5, 6). The 24-hour “local time” wheel 2 in turn causes the rotation of the 12-hour “local time” wheel 9 and the hand 91 which it carries.
- the third wheel 11b of the hour wheel 11 also drives the 12 o'clock "home time” wheel 13 and the hand 131 which it carries via the time setting gear 12.
- a time setting mechanism not illustrated typically makes it possible to directly rotate the time setting reference 12 and thus causes the correction of the display of the local time (local time) and the time of the place of residence (home time).
- the mechanism 1 also includes a local time correction device comprising a first “decrement” function allowing the user to decrement the local time display by one hour and a second “increment” function allowing the user to increment local time display by one hour.
- This device allows the user to easily correct the local time display depending on their location. It includes a function selection system and a control member 20 making it possible to activate the selected function. In practice, the user first selects the “increment” or “decrement” function that he wishes to use then presses a push button 21 to control the selected function, i.e. to increment or decrement the local time display by one hour.
- the function selection system according to the first embodiment of the invention ( figures 1 to 6b ) comprises a connecting rod 30 carrying a stud 31 and a selection rocker 50.
- the stud 31 is intended to move in a guided manner between two stable positions under the influence of movements of the selection rocker 50.
- the “decrement” and “increment” functions are respectively controlled by a first 41 and a second 42 rockers arranged to cooperate with the 24-hour “local time” wheel 2 to rotate it in one direction (clockwise to decrement) or in the other (counterclockwise to increment).
- These first and second flip-flops constitute triggers of said functions.
- the control unit 20 mentioned above is a local time corrector. This is a rocker subjected to the elastic return action of a spring 24 which has a part (forming the push button 21) accessible from outside the watch case 10.
- the movements of the control member 20 are rotational movements around an axis of rotation A1 fixed relative to the board 100. Their amplitude is limited by a sliding system comprising a screw 22 screwed into the board 100 and a hole oblong 23 of the control member 20.
- Actuation of the first rocker 41 makes it possible to decrement the display of local times by one hour and actuation of the second rocker 42 makes it possible to increment the display of local times by one hour.
- this has no impact on the display of the time of the place of residence.
- the aforementioned elastic connection 5, 6 makes it possible to secure in rotation the 24-hour “local time” wheel 2 and the 24-hour “home time” wheel 3 during current operation (excluding change of local time) of the mechanism 1 and also allows the 24-hour “local time” wheel 2 to pivot without driving the 24-hour “home time” wheel 3 (disengagement) when correcting the local time display via push-button 21.
- the selection rocker 50 is pivotally mounted around an axis of rotation A4 by means of a pivoting system, here a ball bearing 51. Its amplitude of pivoting around the axis A4 is limited by stops 52a and 52b .
- the rocker 50 is capable of pivoting between a first extreme position represented in the figure 5a and a second extreme position represented in figure 6a . It carries a pin 53 against which a jumper 54 fixed on the board 100 rests so that each of said two extreme positions is stable.
- the selection flip-flop 50 When the inclined plane identified by the mark 54a of the jumper 54 is in support against the pin 53 ( figures 5a and 5b ), the selection flip-flop 50 is in its first stable position and when the inclined plane identified by the mark 54b of the jumper 54 is resting against the pin 53 ( figures 6a and 6b ), the selection rocker 50 is in its second stable position.
- the selection flip-flop 50 is balanced by means of a heavy pellet 55, typically metallic, illustrated in particular in figures 5a, 5b , 6a and 6b , and carries a display member 56, here a portion of an annular disk.
- a zone 56a of the upper surface of this display member 56 presents an optical contrast with the rest of said upper surface.
- This zone 56a is for example colored, textured, fluorescent or other... It allows the user to see through the dial 14 of the watch 10 which function, "increment” or “decrement", is selected. Alternatively, this information can be displayed otherwise, for example by means of a needle.
- zone 56a When the stud 31 is in its first stable position, zone 56a is visible through a first window 141 of the watch dial 10 and indicates to the user that the “decrement” function is selected. When the stud 31 is in its second stable position, the zone 56a is intended to appear through a second window 142 of the watch 10 (this is the case at the figure 4 ) and tells the user that the “increment” function is selected.
- the selection rocker 50 carries a pin 57 around which the connecting rod 30 is pivotally mounted. Each time the selection rocker 50 alternates from one stable position to another, the connecting rod 30 is therefore moved. His movements are guided by a sliding system composed of an excrescence of the stud 31 extending into a recess 101 in the shape of an inverted F formed in the board 100.
- the stud 31 When the selection rocker 50 is in its first stable position, the stud 31 is in its first stable position, at the level of the junction of the lower arm of the recess in F, as illustrated in figure 5a .
- the selection rocker 50 When the selection rocker 50 is in its second stable position, the stud 31 is in its second stable position, at the level of the junction of the upper arm of the recess in F, as illustrated in Fig. figure 6a .
- the two arms of the recess 101 in F make it possible to guide the stud 31 towards the rocker 41 or 42 selected during actuation of the control member 20.
- the operating principle is as follows:
- the wearer of the watch 10 can, by a simple voluntary movement, typically of his wrist (case of the wristwatch), cause accelerations of the heavy pellet 55 to move the selection rocker 50 from a stable position to the 'other. He can thus select the function (“decrement” or “increment”) that he wishes to use by a simple voluntary movement, typically of his wrist. He can then check the selected function on dial 14 of watch 10. Then, by pressing pusher 21, it activates the selected function by moving pin 31 and therefore the corresponding rocker 41 or 42. It thus corrects the display of the local time (hand 91) without impacting the display of the time of the place of residence (hand 131).
- THE figures 7a and 7b illustrate a watch mechanism 1' for a watch comprising a function selection system according to a second embodiment of the invention.
- the function selection system of mechanism 1' allows the selection of a function chosen from two by a simple movement, typically of the wrist, of the wearer of the watch.
- the mechanism 1' differs from the mechanism 1 only in that, instead of cooperating with a pin 53, the jumper 54 cooperates with a positioning star 53'.
- the positioning star 53' is intended to pivot around the axis of rotation A4 of the rocker 50. It is integral in rotation with the rocker 50.
- the positioning star 53' can only take two positions, the first illustrated in the figure 7a corresponding to the first stable position of the selection flip-flop 50 and the stud 31 and another (not illustrated) corresponding to the second stable position of the selection flip-flop 50 and the stud 31. In this second stable position, the star of positioning 53 ' would have rotated one step clockwise relative to the position illustrated in figure 7a .
- THE figures 8 to 11 illustrate a 1" watch mechanism for a watch comprising a function selection system according to a variant of the second embodiment of the invention.
- the function selection system of the 1" mechanism allows the selection of a function to choose from among four per a simple movement, typically of the wrist, of the wearer of the watch.
- This mechanism 1" differs from the mechanism 1' in that the selection rocker 50" has four stable positions corresponding to the four pivoting positions of the positioning star 53" (identical to the positioning star 53' of the second mode) illustrated in figures 8, 9 , 10 and 11 . Each of these stable positions defines a distinct stable position for the pad 31 and corresponds to the selection of a specific function among four.
- the 30" connecting rod and the 31" stud are identical to those illustrated in figures 1 to 7b but their movements are slightly different.
- the recess 101" made in the board 100 and in which an excrescence of the stud 31" moves (to form a guide slide) has a shape adapted to the third embodiment.
- the inverted “F” defined previously has four arms here instead of two, for four functions instead of two. Each of said arms is arranged to guide the stud 31" to the actuation member or trigger (rocker or other) of the selected function during actuation of the control member 20".
- control member 20" of the mechanism 1" makes it possible to act on the stud 31" so that it activates the selected function. Here it can trigger and/or correct four different functions.
- the function selection system makes it possible to limit the number of control members necessary to operate different functions.
- the star 53', 53" can be replaced by a set of pins (four in the example) playing the role of the four useful teeth of the star 53', 53".
- the jumper 54 can be replaced by an elastic blade comprising two faces.
- the maintenance of the stud 31, 31" in each of its stable positions is ensured by an elastic restoring force, typically a jumper (or an elastic blade), this can alternatively be ensured by a magnetic force, typically by magnets fixed for example on the one hand on the rocker 50, 50" and on the other hand on the board 100.
- an elastic restoring force typically a jumper (or an elastic blade)
- a magnetic force typically by magnets fixed for example on the one hand on the rocker 50, 50" and on the other hand on the board 100.
- control member is a pivoting member, part of which (push button) is accessible from outside the watch case.
- it may be a simple pusher, or any member capable of acting on the movable member (stud) so that it in turn activates the trigger with which it must act.
