Abstract

A shock-proof device ( 200 ) for a movement configured to allow the movement of the horological movement ( 210 ) along at least three degrees of freedom. The shock-proof device ( 200 ) includes at least one damping element ( 230 ) configured to damp the shocks of the horological movement ( 210 ) and a crown ( 100 ) configured to move between a first position ( 101 ) wherein the horological movement ( 210 ) is free along at least three degrees of freedom and a second position ( 102 ) wherein the horological movement ( 210 ) is rigidly connected to the crown ( 100 ).

First claim

The invention claimed is:

1. A shock-proof device for a horological movement ( 210 ), said shock-proof device, comprising:
said horological movement;
a crown ( 100 ) configured to move between a first position ( 101 ) wherein said horological movement ( 210 ) is free along at least three degrees of freedom and a second position ( 102 ) wherein said horological movement ( 210 ) is rigidly connected to said crown ( 100 );
a driven organ ( 110 ) configured to be driven and to be connected to said horological movement ( 210 );
a driving organ ( 120 ) configured to be distant from said driven organ ( 110 ) when said crown ( 100 ) is in said first position ( 101 ) and to be in contact with said driven organ ( 110 ) when said crown ( 100 ) is in said second position ( 102 ); and
a damping element ( 230 ) configured to damp shocks of said horological movement.

2. The shock-proof device according to claim 1 , further comprising an enclosure ( 105 ); said enclosure ( 105 ) includes said driven organ ( 110 ) and/or said driving organ ( 120 ).

3. The shock-proof device according to claim 2 , wherein said enclosure ( 105 ) surrounds said driven organ ( 110 ) and/or said driving organ ( 120 ), and/or said driven organ ( 110 ) surrounds said driving organ ( 120 ).

4. The shock-proof device according to claim 1 , wherein said driven organ ( 110 ) comprises a head ( 113 ) configured to offer an engagement to said driving organ ( 120 ).

5. The shock-proof device according to claim 4 , wherein said head ( 113 ) comprises a contact surface ( 112 ) configured to offer an engagement to said driving organ ( 120 ) when said driven organ ( 110 ) is in contact with said driving organ ( 120 ), and/or a guiding surface ( 111 ) configured to guide said driving organ ( 120 ), preferably, towards said contact surface ( 112 ).

6. The shock-proof device according to claim 5 , wherein said driving organ ( 120 ) being configured to be distant from said contact surface ( 112 ) when said crown ( 100 ) is in said first position ( 101 ) and/or said driving organ ( 120 ) being configured to be in contact with said contact surface ( 112 ) when said crown ( 100 ) is in said second position ( 102 ).

7. The shock-proof device according to claim 1 , wherein said driving organ ( 120 ) has a cylindrical shape configured to engage with said driven organ ( 110 ).

8. The shock-proof device according to claim 7 , wherein said cylindrical shape of said driving organ ( 120 ) forms a female match of said head ( 113 ) of said driven organ ( 110 ).

9. The shock-proof device according to claim 1 , which comprises at least a first joint ( 131 ) and a protective organ; said at least a first joint ( 131 ) being disposed between said crown ( 100 ) and said protective organ ( 130 ).

10. The shock-proof device according to claim 9 , wherein said at least a first joint ( 131 ) is configured to render the space between said crown ( 100 ) and said protective organ ( 130 ) water-resistant.

11. The shock-proof device according to claim 1 , wherein said driven organ ( 110 ) is an end piece ( 110 ) configured to be disposed on a shaft ( 220 ) of said horological movement ( 210 ) or said driven organ ( 110 ) is rigidly connected to a shaft ( 220 ) of said horological movement ( 210 ).

12. The shock-proof device according to claim 1 , further comprising a return organ ( 115 ) configured to move said driving organ ( 120 ) between said first position ( 101 ) and said second position ( 102 ).

13. The shock-proof device according to claim 11 , wherein said shaft ( 220 ) is a winding-mechanism shaft ( 220 ).

14. The shock-proof device according to claim 1 , which comprises a middle ( 250 ) configured to receive said horological movement ( 210 ) protected by said damping element ( 230 ).

15. The shock-proof device according to claim 1 , wherein the driving organ ( 120 ) is a cylindrical female member and the driven organ ( 110 ) is a cylindrical male member which is engaged by the cylindrical female member by being received in the female member.
