Abstract

A sympathetic timepiece assembly ( 1000 ), which includes a clock ( 100 ) and at least one watch ( 200 ) arranged to be deposited in a receptacle 150 included in the clock, in a single transfer position, this sympathetic assembly ( 1000 ) including a connection mechanism between the clock ( 100 ) and each watch ( 200 ) when the watch ( 200 ) is deposited in the receptacle 150 in the transfer position, this connection mechanism includes at least two separate transmission lines, one for transferring power or movement, and the other for selecting a function to be performed or a display variable to be adjusted.

First claim

The invention claimed is:

1. A horological sympathetic assembly ( 1000 ), which includes a clock ( 100 ) and at least one watch ( 200 ) arranged to be deposited in a receptacle ( 150 ) included in said clock ( 100 ), in a single transfer position, said sympathetic assembly ( 1000 ) including a connection mechanism between said clock ( 100 ) and each watch ( 200 ) when said watch ( 200 ) is deposited in said receptacle ( 150 ) in said transfer position, characterised in that said connection mechanism includes at least two distinct transmission lines, one for transferring power or movement, and the other for selecting a function to be performed among a plurality of functions or a display variable to be adjusted among a plurality of display variables, wherein the selected function or display variable may be selected independent of the other plurality of functions or display variables.

2. The sympathetic assembly ( 1000 ) according to claim 1 , characterised in that said connection mechanism includes a first shaft ( 1 ), which is arranged to indicate a desired type of correction and ensure a transmission of a function selection, one of the functions being a neutral/winding function for power recharging said watch ( 200 ).

3. The sympathetic assembly ( 1000 ) according to claim 2 , characterised in that said connection mechanism includes a second shaft ( 2 ) arranged to provide torque transmission for power recharging said watch ( 200 ) from said clock ( 100 ), and/or to ensure a transmission to said watch ( 200 ) of an adjustment or setting value, in the form of an angle of rotation on the basis of a value given by said clock ( 100 ).

4. The sympathetic assembly ( 1000 ) according to claim 3 , characterised in that said second shaft ( 2 ) and said first shaft ( 1 ) are each divided into two half-shafts ( 11 , 12 ; 21 , 22 ) between said clock ( 100 ) and said watch ( 200 ), these two half-shafts being arranged to drivingly cooperate with each other when said watch ( 200 ) is placed on said clock ( 100 ) in said receptacle ( 150 ) in said transfer position.

5. The sympathetic assembly ( 1000 ) according to claim 4 , characterised in that said first shaft ( 1 ) includes a first lower half-shaft ( 11 ) of said clock ( 100 ) and a first upper half-shaft ( 12 ) of said watch ( 200 ), and said second shaft ( 2 ) includes a second lower half-shaft ( 21 ) of said clock ( 100 ) and a second upper half-shaft ( 22 ) of said watch ( 200 ), and in that, when said watch ( 200 ) is absent from said clock ( 100 ) and when said clock ( 100 ) does not carry any said watch ( 200 ), the two half-shafts intended to constitute together said first shaft ( 1 ), which are said first lower half-shaft ( 11 ) and said first upper half-shaft ( 12 ) are each in a neutral position.

6. The sympathetic assembly ( 1000 ) according to claim 5 , characterised in that, when said watch ( 200 ) is placed on said clock ( 100 ) in said receptacle ( 150 ) in said transfer position, said first lower half-shaft ( 11 ) and said first upper half-shaft ( 12 ) on the one hand, and said second lower half-shaft ( 21 ) and said second upper half-shaft ( 22 ) on the other hand, are matched, the function selected is neutral/winding.

7. The sympathetic assembly ( 1000 ) according to claim 4 , characterised in that said clock ( 100 ) includes at least one control means ( 300 ), which is arranged to be operated by a user, or to be controlled by a time base of said clock ( 100 ), to rotate said first lower half-shaft ( 11 ), to select the function of said first shaft ( 1 ).

8. The sympathetic assembly ( 1000 ) according to claim 7 , characterised in that said clock ( 100 ) is arranged to control a sequence of functions when said watch ( 200 ) is placed on said clock ( 100 ), under the control of said control means ( 300 ), for an adjustment of each variable, with a succession of elementary sequences which each correspond to a position of said first shaft ( 1 ), and which start according to a timing imposed by the time base of said clock ( 100 ).

9. The sympathetic assembly ( 1000 ) according to claim 8 , characterised in that said time base of said clock ( 100 ) is arranged to impose a predetermined duration between two said successive elementary sequences.

10. The sympathetic assembly ( 1000 ) according to claim 3 , characterised in that said clock ( 100 ) is arranged to deliver a torque to said second shaft ( 2 ) in the presence of said watch ( 200 ), and includes a regulating mechanism for regulating a rotation of said second shaft ( 2 ).

11. The sympathetic assembly ( 1000 ) according to claim 3 , characterised in that each said watch ( 200 ) is arranged to release or block the rotation of said second shaft ( 2 ) depending on a level of power stored in said watch ( 200 ) according to a defined hysteresis, by a power reserve mechanism.

12. The sympathetic assembly ( 1000 ) according to claim 3 , characterised in that said sympathetic assembly ( 1000 ) is arranged to impose a number of successive elementary sequences corresponding to successive adjustments of a date value, an hour value, a minute value, and a second value, respectively, and to clock several said successive elementary sequences, during a first elementary sequence said clock ( 100 ) is arranged to rotate said first shaft ( 1 ) to a date position, and to rotate said second shaft ( 2 ) by an angle corresponding to the date position of said first shaft, wherein said watch ( 200 ) is arranged to recognise the date position of said first shaft ( 1 ) and stop a resonator, and position the date value, the hour value, the minute value and the second value in a zero position, and apply a value transmitted by said second shaft ( 2 ) to a display a date display.

13. The sympathetic assembly ( 1000 ) according to claim 12 , characterised in that said clock ( 100 ) is arranged to trigger, after a first predetermined duration D 1 after said first elementary sequence, a second elementary sequence, and during the second elementary sequence said clock ( 100 ) is arranged to rotate said first shaft ( 1 ) to an hour position, and to rotate said second shaft ( 2 ) by an angle corresponding to the hour position of said first shaft, wherein said watch ( 200 ) is arranged to recognise the hour position of said first shaft ( 1 ), and apply a value transmitted by said second shaft ( 2 ) to a display or an hour display.

14. The sympathetic assembly ( 1000 ) according to claim 13 , characterised in that said clock ( 100 ) is arranged to trigger, after a second predetermined duration D 2 after said second elementary sequence, a third elementary sequence, during said third elementary sequence said clock ( 100 ) is arranged to rotate said first shaft ( 1 ) to a minute position, and to rotate said second shaft ( 2 ) by an angle corresponding to the minute position of said first shaft, added to the third predetermined duration D 3 , which separates said third elementary sequence from a next change of elementary sequence for a release of the running of said watch ( 200 ), wherein said watch ( 200 ) is arranged to recognise the minute position of said first shaft ( 1 ), and apply a value transmitted by said second shaft ( 2 ) to a display or a minute display.

15. The sympathetic assembly ( 1000 ) according to claim 14 , characterised in that said clock ( 100 ) is arranged, after said third predetermined duration D 3 , to return said first shaft ( 1 ) to a neutral/winding position, wherein said watch ( 200 ) is arranged to recognise the neutral/winding position of said first shaft ( 1 ), and to release the resonator and resume operation.
