Description

Technical area

The present invention relates to mechanical timepieces. It relates more particularly to a mechanism for displaying several different horometric information items from each other comprising several information carriers on each of which is one of said horometric information. The present invention also relates to a timepiece comprising such a display mechanism.

State of the art

Such a mechanism for displaying a plurality of different horometric information items comprising a plurality of information media on each of which is one of said horometric information is traditionally used in mechanical timepieces in order to display different information on the dial. horoscopes, such as the date, the time according to different time zones, the phases of the moon, etc.

This information is displayed by means of different wickets or indexes distributed on the dial of the timepiece. Once the timepiece is built, the position of the different information displayed on the dial is immutable, so that it is not possible to change the appearance of the dial.

In addition, all the horometric information appear systematically while their display is no longer necessarily desired by the user.

Furthermore, each information carrier and its actuating mechanism occupy, under the dial, a large space so that the dial and the movement are very congested, which does not allow to have other displays or other mechanisms for lack of space.

A solution to solve this problem has been proposed in the patent EP 1 922 591 which describes the use of one or two rotary indicators kinematically connected to cams in order to "update" the indicators when the associated cams are selected according to the type of information to display selected. The cam is selected by means of a finger which moves in translation to read the information on the cam and transmit it to the associated indicator to "update" it. However, in this display mechanism, the indicators are fixed behind a window so that the appearance of the dial can not be changed. In addition, the indicators used are the same regardless of the type of information to display. This means that the information to be displayed must be of the same nature. WO 2006/134171 presents a portable electronic device having different presentation sets, each with a given control functionality.

An object of the present invention is therefore to overcome these disadvantages, by providing a display mechanism for selecting the horometric information to be displayed.

The tray 36 of the magazine 6 as well as the information carriers 8 are arranged to slide perpendicular to the general plane of the movement along said second set of pins 50, said pins 50 being in particular introduced into the housings 30 provided on the ring 22 of the information carrier 8. In addition, each pin 50 is interrupted to form a passage and allow the extraction of the support of information 8 selected from the store 6, as shown more specifically the figure 4a .

At the top of the magazine 6 is an information carrier 52 mounted to rotate about an axis 54 mounted in the upper housing of the magazine 6. Such an information carrier 52 is for example a disc comprising graduations allowing the display of the local time by means of an index provided on the ice protecting said disk. Said information carrier 52 moves in translation with the other information carriers 8 stored in the magazine 6, but remains in its housing.

Said information carrier 52 is integral with a ring gear 56 having an external toothing 58. There is also provided on the fixed frame 42 a shaft 59 (visible on the figures 1 and 2 ) pivotally mounted and comprising at its upper end a pinion 60 meshing with the external toothing 58 of the ring 56, and at the lower end a first element of a set of references kinematically connected to a wheel hours to turn the information carrier 52 at the speed of hours. The pinion 60 is sufficiently long so that the external toothing 58 of the ring gear 56 remains in mesh with said pinion 60 when the information carrier 52 slides with the magazine 6.

With reference to the figure 5 , the first actuating means 40 arranged to move the magazine 6 comprise a selection arm 62, accessible to a user and secured to a plate 240 pivotally mounted on the fixed frame 42, so that the angular displacement of the selection arm 62 causes translational movement of the tray 36 of the magazine 6. For this purpose, there is provided a reduction gear comprising a pinion 64 pivotally mounted on the plate 240. Said pinion 64 meshes with an internal toothing 66 of a fixed wheel 68 provided on the frame and is also secured to a gearwheel 70 cooperating with a gearwheel 72 integral with a nut 74 having an internal thread 75. Furthermore, there is provided, integral with the plate 36, a screw 76 having an external thread. arranged to cooperate with the internal thread 75 of the nut 74.

Thus, an angular displacement of the selection arm 62 causes an angular displacement of the pinion 64 which, cooperating with the toothing 66, pivots on its axis, causing the toothed wheel 70 to rotate, causing the toothed wheel 72 to rotate. the nut 74. The rotation of the nut 74 causes the displacement in translation of the screw 76, and therefore of the plate 36 and the magazine 6.

With reference to figures 2 and 5 , the first displacement means 12 of the selected information carrier 8 comprise an arm 80 pivotally mounted between the magazine 6 and the platform 10, said arm 80 having means for gripping the selected information carrier 8 arranged to extract the selected information carrier of its housing 38 in the magazine 6. More specifically, the arm 80 has the shape of a fork with two branches, whose ends have protrusions 81 arranged to be housed in the housing 32 provided on the The arms of the arm 80 are dimensioned to position themselves around the ring 22 of the selected information carrier 8. Advantageously, one or two of the housings 30 used to position the information carrier 8 in the magazine 6 by means of the pins 50 can also be used as housings 32 for accommodating one or two of the protrusions 81 of the arm 80.

The arm 80 is motorized by means of an independent cylinder 234 (cf. figure 14 ), and engaged by means of a pusher 248 (cf. figures 1 and 14 ), or any other suitable means. In the center of the arm 80 is a cycle reserve 82 arranged to indicate the reserve of the barrel of the arm 80. A cycle corresponds to the output of an information carrier 8 and its return to the magazine 6. The display of the cycle reserve 82 is dragging.

The arm 80 is mounted integral on a toothed actuating wheel 84, the assembly being mounted free to rotate about an axis 86 mounted on the frame, said axis 86 being the axis about which pivots a centralized control block 88 This centralized control block 88 comprises, integrally connected, in particular a control wheel of the arm in the clockwise direction 90, a control wheel of the arm in counterclockwise direction 92, and a feed wheel 94 kinematically connected to the barrel. arm drive independent 80 through a pinion 95 visible on the figure 1 .

Such a mechanism is known to those skilled in the art and does not require more details.

The centralized control block 88 also comprises a safety wheel 108 comprising two teeth acting as a cam for actuating a jumper (not shown) in order to release any pressure on the arm 80 during its movement and to reposition it by pressing on the arm 80 to ensure the proper positioning of the arm 80 when the information carrier 8 is in the active or inactive position.

According to another variant embodiment shown on the Figures 9 to 13 , there is provided a first safety device to ensure the maintenance in position of the first moving means 12, and more specifically of the arm 80, when the information carrier 8 is in the active or inactive position. For this purpose, the safety device comprises a safety lever 200 arranged to move between an armed position in which it exerts pressure on the arm 80 to hold it in position once said arm 80 has placed the information carrier 8 in the active or inactive position and a disarmed position in which it leaves free the arm 80 to move to place the information carrier 8 in the active or inactive position. The safety device also comprises means for arming said safety lever 200 arranged to position it in its armed position as well as disarming means of said safety lever arranged to position it in its disarmed position. More specifically with reference to the figure 10 , the safety device comprises a bridge 202 on one side of which is pivotally mounted the safety lever 200. The latter comprises at each of its ends a nose 200a, 200b whose shape is chosen to allow the best possible contact with a pin 204, 206 respectively, provided on the arm 80 (cf. figures 9 , 12 and 13 ). In addition, the safety lever comprises an additional branch 200c, lateral, having the shape of a rake whose function will be described below. The safety lever 200 is also provided with a jumper 208.

The arming means of the safety lever 200 comprise a winding pinion 210 provided with a toothed sector pivotally mounted on the bridge 202 on the side opposite to the safety lever 200, and two pinions 212, 214 pivotally mounted on the bridge of the same side as the safety lever, the first gear 212 being secured to the winding pinion 210 and the second gear 214 cooperating on the one hand with the first pinion 212 and on the other hand with the rake of the additional branch 200c of the safety lever 200. As shown in figure 11 , the armoring means also comprise a winding cam 216 pivotally mounted on the bridge 202 on the same side as the winding pinion 210, said winding cam 216 being integral with the second pinion 214.

With reference to the figure 11 , the disarming means comprise a disarming lever 218 pivotally mounted on the bridge 202 on the same side as the winding pinion 210. The disarming lever 218 comprises a disarming finger 220 whose function will be described below. The disarming lever 218 also comprises a spout 222 arranged to cooperate with the arming cam 216 and to block it. The disarming lever 218 is provided with a jumper 224.

Moreover, as shown in figure 10 , the centralized control unit 88 comprises a safety wheel 226 comprising toothed sectors 227, 228 arranged to cooperate with the toothed sector of the winding pinion 210 and two teeth 229, 230 arranged to cooperate with the disarming finger 220 of the disengaging rocker 218. The toothed sectors 227, 228 and the teeth 229, 230 are distributed on the security wheel 226 so as to trigger the safety device at the appropriate moments.

The operation of the safety device is as follows: with reference to the figure 12 when the arm 80 is placed in front of the magazine 6, the information carrier being in the inactive position, the safety lever 200 is in the armed position, its nose 200a pressing on the pin 204 so as to keep the arm 80 in this position . The arming cam 216 is blocked by the spout 222, so the entire arming mechanism is locked, and thus also the rake 200c. As a result, the safety lever 200 is immobilized against the arm 80. When the user has started a cycle, the safety wheel 226 rotates so that one of the teeth 229, 230 cooperates with the disarming device 220. so as to raise the disarming lever 218 and thereby release the arming cam 216. The arming mechanism is then no longer blocked so that the rake 200c, and therefore the safety lever 200, falls into its disarmed position. . The arm 80 can then disengage and pivot. When the arm 80 is positioned in front of the platform 10 to place the information carrier in the active position, the security wheel 226 rotates so that one of the toothed sectors 227, 228 cooperates with the winding pinion 210 for rotate it. The rotation of the winding pinion 210 causes the rotation of the first pinion 212, and therefore the second pinion 214, and thus of the arming cam 216 on the one hand and the rake 200c of the safety lever 200 on the other hand. The safety lever 200 is raised to return its nose 200b against the pin 206 and press the safety lever 200 to hold it in position, as shown in FIG. figure 13 . At the same time, the arming cam 216 pivots to cooperate with the spout 222 of the disarming lever 218 and block it, so that the security device is armed and locked. Then the same disarming and arming cycle resumes.

The other elements of the centralized control block 88 will be described later.

The outer periphery of the intermediate ring 119b extends above a shoulder provided on the inner periphery of the intermediate ring 119a. The trays 119a, 119b and 138 are free with respect to each other. Thus, when the shaft 124 moves downwardly in translation, the central plate 138 presses on the intermediate ring 119b which bears on the ring 119a so that the drive pins 115a, 115b and the dotted pins 117a, 117b go down in low position.

A leaf spring 121 is provided respectively to raise each of the intermediate rings 119a, 119b when the central plate 138 exerts no more pressure, so that the drive pins 115a, 115b and the pin points 117a, 117b back up. high position.

The displacement in translation, perpendicularly to the general plane of movement, of the drive pins 115a, 115b and the pin-points 117a, 117b between their low position and their high position is achieved by means of the second displacement means provided on the platform. form 10.

Said second displacement means 126 comprise the intermediate rings 119a, 119b, the shaft 124 and its central plate 138, as well as a ring gear 128 arranged to cooperate, via the referrals necessary, with a control wheel 130 of the platform 10 integral with the other control wheels of the centralized control block 88. The control wheel 130 of the platform 10 comprises four tooth sectors of 30 ° distributed around said control wheel 130 of the platform 10 so that a rotation of 30 ° of the control wheel 130 of the platform 10 causes a rise in the up position or a lowering in the low position of the drive pins 115a, 115b and dotted pins 117a, 117b when the ring gear 128 is kinematically connected to the toothed sectors of the control wheel 130 of the platform 10.

The ring gear 128 is integral with a tube 132 mounted to rotate about a shaft 134 fixed to the frame and coaxial with the shaft 122 and the shaft 124 around which it is mounted. The tube 132 comprises on its inner periphery a helical cam 136 arranged to cooperate with a helical cam provided on the outer periphery of the shaft 124. Thus, a rotation of the ring gear 128 causes a displacement in translation, perpendicular to the general plane of the movement both upwardly and downwardly of the shaft 124 which is slidably mounted on the shaft 134, and thus a displacement in translation, perpendicular to the general plane of movement, of the central plate 138.

In order to help the selected information carrier 8 to position itself on the platform 10, the mechanism according to the invention further comprises clutch means arranged to rotate the selected information carrier 8 positioned on the platform -form 10 until said selected information carrier 8 cooperates with the associated crown 112a, 112b.

With reference to the figure 8 , said clutch means comprise a clutch frame 150 integral with the movement frame and a rocker 152 pivotally mounted on the clutch frame 150 about an axis 154. On the rocker 152 are pivotally mounted a clutch gear 156 and a first element of a gear train connected to the clutch gear 156 by means of a friction system 158. The clutch gear 156 is arranged to engage in the cutout 34 provided on the ring 22 of support 8 and mesh with the outer peripheral teeth 20 provided on the base of the disk 16. The flip-flop 152 allows the clutch gear 156 to tilt slightly and move apart to allow the positioning of the information carrier 8 selected on the platform 10.

A jumper 160 provided on the clutch frame 150 cooperates with a pin 162 provided on the latch 152 to ensure the positioning of the clutch gear 156.

The gear also includes the wheel 164, mounted on the clutch frame 150 and kinematically connected to the second actuating means of the clutch means. Said second means for actuating the clutch means are advantageously constituted by a clutch control wheel 166 integral with the other control wheels of the centralized control block 88. The clutch control wheel 166 comprises a gear sector of 120 ° so that a 120 ° rotation of the clutch control wheel 166 causes the disk 16 to rotate a maximum of 400 °, until the drive pins 115a, 115b and the dotting pins 117a, 117b are correctly positioned in the associated disc so that it cooperates with its associated crown 112a, 112b.

According to a variant not shown, the disk may comprise on its underside pins representative of a melody and the platform may carry a comb arranged to cooperate with the pins to form a melody, in the manner similar to a box. music. Different discs can be provided to offer different melodies. In this case, the platform is adapted so that the disc is driven by the clutch means only.

The different toothed sectors of the control wheels are arranged relative to each other as a function of the evolution of the output cycle and the return of the selected information carrier 8 of the magazine.

The course of such a cycle is as follows: the user actuates the selection arm 62 in order to translate the magazine 6 in translation and to bring the selected information carrier 8 to the arm 80 so that its excrescences 81 engage in the housing 32 provided on the ring 22 of the information carrier. If the cycle reserve is sufficient, the cycle starts when the user activates triggering means of the mechanism such as the pusher 248 which engages the unwinding of the barrel 234 and therefore the power supply of the centralized control block 88 by the wheel 94.

According to a preferred embodiment of the triggering means of the display mechanism represented on the figure 14 , said triggering means of the display mechanism of the invention comprise the pusher 248 integral with a rocker 260, an arm comprises a first spout 262, a locking lever 264 comprising a nose 266 arranged to cooperate with the spout 262, and a locking cam 268 of the barrel 234 arranged to cooperate with the locking lever 264. When the user presses on the pusher 248, the spout 262 cooperates with the nose 266 of the locking lever 264 which raises up so that the cam blocking 268 is released and allows the rotation of the barrel 234.

The triggering means of the display mechanism are also arranged to cooperate with a power reserve 269. For this purpose, the arm of the rocker 260 comprises a second nozzle 270 arranged to cooperate with a pin 271 provided at the end of FIG. an arm of a rocker 272 power reserve. Another arm 274 of said power reserve latch 272 cooperates with a power reserve cam 276. When the power reserve is exhausted, the power reserve cam 276 is positioned so that the power reserve latch 272 pivots to position its pin 271 on the path of the second nose 270. Thus, when the user presses the push 248, the second spout 270 comes into contact with the pin 271 which prevents the displacement of the first spout 262 to the locking lever 264 and thus disengage the triggering means of the mechanism.

In addition, the power reserve latch 272 is secured to a second pin 254 whose function will be described below.

With reference to Figures 15 to 17 , there is further provided a second safety device of the start of the display mechanism of the invention arranged to allow on the one hand said mechanism to occupy a normal operating position when the magazine 6 repositioned correctly after its displacement and to allow on the other hand said trigger means to occupy their disengaged position preventing any movement of the first moving means 12, and therefore the arm 80, when the magazine 6 is not positioned correctly, and more particularly when it does not reposition properly after moving. With reference to figures 15 and 16 this second safety device for the start of the display mechanism comprises as many positioners as information carriers 8, namely here three positioners 242 mounted on the plate 240. Each positioner 242 has a circular sector shape, the outer peripheral rim having a notch 243 whose function will be described below. Each positioner 242 comprises at its center an oblong opening 244 through which the fixing screws 245 of the positioner 242 are introduced. This makes it possible to precisely adjust the position of each positioner 242. The safety device for starting the mechanism display also comprises a first lever 246 pivotally mounted on the frame and comprising a locating nose 247 corresponding to the notches 243. The lever 246 is arranged on the one hand so that its locating nose 247 is engaged in one of the notches 243 when the magazine 6 is in its normal operating position after its displacement and secondly to cooperate with the triggering means of the display mechanism, and more specifically to disengage the pusher 248, when the magazine 6 does not reposition correctly after its displacement and that the locating spout 247 is no longer engaged in one of the notches 243, as represented by on the figure 17 . For this purpose, the safety device of the start of the display mechanism also comprises a second lever 250 pivotally mounted on the frame and comprising a first arm 251 carrying a first pin 252 arranged to cooperate with the first lever 246 and a second arm 253 arranged to press on the second pin 254 secured to the power reserve rocker 272 when the locating nose 247 is not engaged in one of the notches 243. Thus, when the locating nose 247 is not engaged in one of the notches 243, the first lever 246 tilts the second lever 250 by pushing the first pin 252, so that its second arm 253 moves the second pin 254 and thus the reserve latch 272 Steps. The latter pivots and is then in the same position as when the power reserve is exhausted, as described above. Thus, when the positioning spout 247 is not engaged in one of the notches 243, the barrel 234 remains locked and therefore the arm 80 can not move. The cycle is stopped until the user actuates the selection arm 62 to properly position the magazine 6 so that the locating spout 247 engages one of the notches 243. The second pin 254 and thus the power reserve rocker 272 return to position to allow the release of the barrel 234 by actuation of the pusher 248.

The arrangement of the various toothed sectors of the control wheels of the centralized control block 88 is such that the second displacement means 126, and in particular the ring gear 128, are first actuated so as to lower the shaft 124 and therefore the drive pins 115a, 115b and the pin pins 117a, 117b in the down position.

The arrangement of the various toothed sectors of the control wheels of the centralized control block 88 is such that it is then actuated, by means of the control wheel of the arm in the clockwise direction 90 cooperating with the pinion 96, the arm 80 in the clockwise, in order to bring the information carrier 8 selected above the platform 10, the drive pins 115a, 115b and the pinning pins 117a, 117b are retracted in the low position.

In another embodiment of the invention, a third safety device can be provided to prevent the movement of the magazine 6 in case of actuation of the selection arm when the arm 80 is no longer positioned in front of the magazine 6. In this variant, with reference to Figures 18 to 22 , the selection arm corresponding to the selection arm 62 shown on the figure 5 is now referenced 277 and here is integral with a ring 278, the assembly being pivotally mounted on the frame, under the plate 240. The actuating means 40 comprising the pinion 64, the internal toothing 66, the toothed wheel 70 and the toothed wheel 72 integral with the nut 74 remain identical to what has been described above.

Said third safety device comprises a lever 280 pivotally mounted on the frame and having two branches 280a, 280b integral, and a cam 281 pivotally mounted on the plate 240. The lever 280 is positioned so that its branch 280b can cooperate with a pin 207 (cf. figures 9 , 12 , 13 , and 22 ) provided on the arm 80 when the latter is positioned in front of the magazine 6. The cam 281 comprises a generally circular portion 282, eccentric with respect to the axis of the nut 74, and having a flange 283 arranged to cooperate with a pin 284 provided at the end of the leg 280a of the lever 280. The cam 281 also comprises an arm 286 substantially concentric with the circular portion 282 and having an oblong opening 288 whose function will be described below. The third safety device also comprises two clamps 290 and 292, the clamp 292 being secured to a shaft 294 (cf. figure 20 ) pivotally mounted through the plate 240 and the clamp 290 being connected to the clamp 292 by a finger 293 provided on the clamp 292 and engaged in a notch 295 of the clamp 290. The shaft 294 carries an arm 296 on which is provided a pin 298, arranged to circulate in the oblong opening 288 of the cam 281. The third safety device also comprises the ring 278 whose circumference has two notches 302 arranged to respectively receive a clamp 290, 292. Thus, when the arm 80 moves between the magazine 6 and the platform 10, its pin 207 moves apart and releases the leg 280b of the lever 280. The lever 280 pivots under the action of its return spring 304 so that its pin 284 supports on the flange 283 of the cam 281 to rotate it. The pivoting of the cam 281 causes the pin 298 to move in the oblong opening 288 so as to rotate the shaft 294 and thus the gripper 292. The gripper 292 opens and disengages from its notch 302. The other gripper 290 follows the same movement and disengages from its notch. so that the ring 278 is disengaged from the plate 240 and disengaged, as shown by the figures 18 and 19 . Therefore, if the selection arm 277 is angularly displaced, the ring 278 rotates in front of the clamps 290 and 292 without being able to cooperate with them. The plate 240 is not rotated, the first actuating means for moving the magazine 6 are not actuated. The magazine 6 can not be moved, and that as the arm 80 is not repositioned in front of the magazine 6. When the arm 80 returns to the magazine 6, its pin 207 again press the 280b branch of the lever 280 so as to move the cam 281, and therefore the pin 298, which causes the rotation of the shaft 294 and the closure of the clamps 290 and 292 in their notches 302 provided on the ring 278, as shown by the figures 20 and 21 . The ring 278 is thus again integrally connected to the plate 240 so that the actuation of the selection arm 277 causes the displacement of the magazine 6 as described above.

The arrangement of the various toothed sectors of the control wheels of the centralized control block 88 is such that the second displacement means 126, and in particular the ring gear 128, are then actuated again so as to raise the shaft 124 and thus the drive pins 115a, 115b and the pin points 117a, 117b in the high position.

The arrangement of the various toothed sectors of the control wheels of the centralized control block 88 is such that the clutch gear 156 meshing with the disc 16 is then actuated until the associated drive pin 115a, 115b and the associated timing pin 117a, 117b are correctly positioned in the base 17 of the disc 16, which causes the clutch gear 156 to disengage. The cycle is then stopped by stopping the rotation of the centralized control block 88.

The disk 16 is now secured to its associated crown 112a, 112b, and rotates on the platform at the appropriate speed as a function of the information displayed. The ring 22 held by the arm 80 positioned in front of the platform 10, remains fixed, as well as the ice 24, which allows to read the information by means of the indexes 26 provided on the ice 24. Because the rings 112a, 112b rotate continuously, even when their associated disk 16 is not positioned on the platform 10, the memory of the information is retained and the associated disk 16 is automatically updated when it is set up on the platform 10.

When the user again wishes to modify the information carrier in place on the platform 10, he actuates the pusher to restart the barrel and the rotation of the centralized control block 88.

The arrangement of the various toothed sectors of the control wheels of the centralized control block 88 is such that the second displacement means 126 are again actuated, and in particular the ring gear 128, so as to lower the shaft 124 and thus the drive pins 115a, 115b and the pin tumblers 117a, 117b in the down position.

The arrangement of the different toothed sectors of the control wheels of the centralized control block 88 is such that it is then actuated, by means of the control wheel of the arm in the counterclockwise direction 92 cooperating with the pinion 100, the arm 80 counter-clockwise, in order to bring back the information carrier 8 selected in the magazine 6.

The arrangement of the various toothed sectors of the control wheels of the centralized control block 88 is such that the second displacement means 126, and in particular the ring gear 128, are then actuated again so as to raise the shaft 124 and thus the drive pins 115a, 115b and the pin points 117a, 117b in the high position. Then the cycle stops. As shown in figure 4b the arm 80 remains in front of the magazine 6 and serves as a stop to prevent the information carrier 8 placed at its level from the store 6 inadvertently.

Thus, the user can modify as desired the information carrier 8 positioned on the platform so as to display, in the same place, different horometric information.

It is obvious that the present invention is not limited to the embodiment described. In particular the number of crowns can vary.

Furthermore, the various safety devices as well as other devices such as the platform or the control block can be used independently in other mechanisms than the display mechanism of the invention. For example, the first security device can be used to secure the position of a chronograph arm. The second security device may be used in a striking mechanism to prevent the ringing from being initiated if the mechanism is in its set time position. The third security device can be used in a ringing mechanism to prevent setting the time if the user has already started the ring.
