Abstract

A mechanical timepiece movement in the form of a modular unit. The movement includes at least one modular unit for performing a particular timepiece function, which is irremovably pre-adjusted by irremovably securing adjustment and/or assembling components included in the functional module after the particular horological function has been adjusted and function checked on the test bench. The pre-adjusted functional module is irremovably secured to a plate included in the movement or included in another pre-adjusted functional module of the movement, or irremovably secured to another pre-adjusted functional module included in the movement.

First claim

What is claimed is:

1. A mechanical timepiece movement in the form of a modular unit, wherein said movement includes a plurality of mechanical functional modules each performing a particular timepiece function, said functional modules being irreversibly adjusted prior to securing of adjustment and assembly components comprised in said functional modules, wherein no further adjustment of said functional modules is possible after said adjustment and assembly components are irremovably secured such that said functional modules cannot be dismantled from said movement, wherein each of said adjusted functional modules is irremovably secured to a plate comprised in said movement or comprised in another adjusted functional module of said movement, or is irremovably secured to another adjusted functional module comprised in said movement, and wherein at least one of said adjusted functional modules is irremovably secured to a front of the plate and at least one of said adjusted functional modules is irremovably secured to a back of the plate.

2. The timepiece movement according to claim 1 , wherein said functional modules are each irremovably secured, directly or indirectly relative to said plate, or sandwiched between functional modules or components of said movement which are in turn irremovably secured directly or indirectly relative to said plate.

3. The timepiece movement according to claim 1 , wherein each of said adjusted functional modules is derived from a sub-assembly comprising all the components required to perform a particular timepiece function of transforming a movement between at least one input wheel set and at least one output wheel set.

4. The timepiece movement according to claim 3 , wherein said movement includes at least one of said adjusted functional modules which is a motor module and includes at least one barrel and the input wheel set of which is formed by a barrel arbour, which cooperates with a ratchet arranged to be pivoted, either by a manual winding mechanism or by a winding and time-setting mechanism or by a self winding mechanism or by a self winding module to wind at least one spring in at least one drum forming said output wheel set of said motor module, said drum being arranged to drive an input pinion of a gear train or gear train module.

5. The timepiece movement according to claim 3 , wherein said movement includes at least one of said adjusted functional modules which is a gear train module, the input wheel set of which is formed by an input pinion arranged to cooperate with a drum, and a first output wheel set of which is formed by a fourth wheel arranged to cooperate with an escape pinion connected to an escape wheel comprised in an escape mechanism or a regulating module.

6. The timepiece movement according to claim 5 , wherein said movement includes a second output wheel set which is formed by a display train arranged to cooperate, either with a display mechanism comprised in said gear train module, or with a display module external to said gear train module.

7. The timepiece movement according to claim 3 , wherein said movement includes at least one of said adjusted functional modules which is a display module, the input wheel set of which is formed by a display train comprised in a gear train mechanism or a gear train module and the output wheel set of which is formed by at least one indicator arranged to cooperate with a complementary indicator or with a dial comprised either in said display module or a timepiece incorporating said module.

8. The timepiece movement according to claim 3 , wherein said movement includes at least one of said adjusted functional modules which is a time-setting module, the input wheel set of which is formed by a stem arranged to be moved by a user, and a first input wheel set of which is formed by a motion work control train.

9. The timepiece movement according to claim 8 , wherein said time-setting module is a time-setting and winding module and includes a second output wheel set which is formed by a winding control train.

10. The timepiece movement according to claim 3 , wherein said movement includes at least one of said adjusted functional modules which is a regulating module comprising an adjustment unit, and the input wheel set of which is formed by an escape wheel arranged to be moved by a fourth wheel comprised in a gear train or gear train module, and the output wheel set of which is formed by said same escape wheel.

11. The timepiece movement according to claim 3 , wherein said movement includes at least one of said adjusted functional modules which is a self-winding module, the input wheel set of which is formed by an oscillating weight moved by the motions of a user or an external tool, and the output wheel set of which is formed by a drive train of a ratchet comprised either in a motor mechanism, or a motor module, or a ratchet which meshes with a barrel arbour comprised either in a motor mechanism or a motor module.

12. A timepiece including at least one movement according to claim 1 .

13. The timepiece movement according to claim 1 , wherein the movement comprises a balance spring that is not secured to an index assembly.

14. The timepiece movement according to claim 1 , wherein the movement comprises a pin driven through both sides of the plate where both ends of the driven-in pin are welded to mechanical functional modules.

15. A mechanical timepiece movement in the form of a modular unit, wherein said movement includes a plurality of mechanical functional modules each performing a particular timepiece function, said functional modules being irreversibly adjusted prior to securing of adjustment or assembly components comprised in said functional modules, wherein no further adjustment of said functional modules is possible after said adjustment or assembly components are irremovably secured such that said functional modules cannot be dismantled from said movement, wherein each of said adjusted functional modules is irremovably secured to a plate comprised in said movement or comprised in another adjusted functional module of said movement, and is irremovably secured to another adjusted functional module comprised in said movement, and wherein at least one of said adjusted functional modules is irremovably secured to a front of the plate and at least one of said adjusted functional modules is irremovably secured to a back of the plate.

16. The timepiece movement according to claim 15 , wherein said functional modules are each irremovably secured, directly or indirectly relative to said plate, or sandwiched between functional modules or components of said movement which are in turn irremovably secured directly or indirectly relative to said plate.

17. The timepiece movement according to claim 15 , wherein each of said adjusted functional modules is derived from a sub-assembly comprising all the components required to perform a particular timepiece function of transforming a movement between at least one input wheel set and at least one output wheel set.

18. The timepiece movement according to claim 17 , wherein said movement includes at least one of said adjusted functional modules which is a motor module and includes at least one barrel and the input wheel set of which is formed by a barrel arbour, which cooperates with a ratchet arranged to be pivoted, either by a manual winding mechanism or by a winding and time-setting mechanism or by a self winding mechanism or by a self winding module to wind at least one spring in at least one drum forming said output wheel set of said motor module, said drum being
