Abstract

A clockwork column selector mechanism, including a mobile with columns protruding above a base surface separated by clearances, forming slots along a profile, arranged to, in certain positions of the mobile, enable the insertion of a feeler-spindle into a clearance in a transverse direction substantially normal to the profile and parallel to the reference surface, and to, in other positions of the mobile, stop a feeler-spindle on a transverse surface of a column, at least one column including an intermediate transverse stopping surface constituting a stop bearing surface of a feeler-spindle and enable a partial insertion of a feeler-spindle in the thickness of one the slot, and which is located, in a transverse direction, between the geometric envelopes of two end transverse surfaces transversely delimiting this column.

First claim

The invention claimed is:

1. A clockwork column selector mechanism, comprising:
a mobile including a plurality of columns protruding above a base surface and separated by clearances, said columns and said clearances together forming slots extending along a profile, arranged to, in certain positions of said mobile, enable the insertion of a feeler-spindle or a pin into one said clearance in a transverse direction substantially normal to said profile and substantially parallel to said base surface, and to, in other positions of said mobile, stop a feeler-spindle or a pin on a transverse surface of a first column of said plurality of columns, wherein at least said first column includes at least one intermediate transverse stopping surface which is arranged to constitute a stop bearing surface of one said feeler-spindle or one said pin and enable a partial insertion of one said feeler-spindle or one said pin in the thickness of one said slot, and which is located, in said transverse direction, between the geometric envelopes of two end transverse surfaces which transversely delimit said first column,
wherein each column of the plurality of columns that includes at least one said intermediate transverse stopping surface has a variable thickness in said transverse direction, and includes at least one projection arranged to retain said feeler-spindle or said pin of a clockwork mechanism arranged to cooperate with said selector mechanism, said projection including said intermediate stopping surface and a front stopping surface in the direction of said profile, and
wherein said first column includes at least two of said projections, each arranged to retain one said feeler-spindle or one said pin in one orientation opposite to the other.

2. The selector mechanism according to claim 1 , wherein at least one column of said plurality of columns includes at least one bearing that extends in an axial direction perpendicular to said base surface.

3. The selector mechanism according to claim 2 , wherein said bearing is limited by one said intermediate transverse stopping surface.

4. The selector mechanism according to claim 1 , wherein said mobile extends along said profile, which is closed, and wherein said slots extend between an outer envelope geometric surface defined by the outer end transverse surfaces of said plurality of columns, and an inner envelope geometric surface defined by the inner end transverse surfaces of said plurality of columns.

5. The selector mechanism according to claim 4 , wherein said closed profile is circular, and wherein said outer envelope geometric surface and said inner envelope geometric surface are cylindrical and coaxial.

6. The selector mechanism according to claim 1 , wherein said profile is closed, and wherein said at least one projection is outside said mobile.

7. The selector mechanism according to claim 6 , wherein each said projection is outside said mobile.

8. A timepiece comprising at least one horological movement, and at least one chronograph mechanism including at least one selector mechanism according to claim 1 , controlled by control means accessible to the user.

9. The selector mechanism according to claim 1 , wherein said at least one intermediate transverse stopping surface is a concave surface arranged facing inwardly towards a central axis of the selector mechanism.

10. The selector mechanism according to claim 1 , wherein said two end transverse surfaces include an inner transverse surface and an outer transverse surface, an entirety of the outer transverse surface being positioned radially outside of an entirety of the inner transverse surface with respect to a central axis of the selector mechanism.

11. A clockwork column selector mechanism, comprising:
a mobile including a plurality of columns protruding above a base surface and separated by clearances, said columns and said clearances together forming slots extending along a profile, arranged to, in certain positions of said mobile, enable the insertion of a feeler-spindle or a pin into one said clearance in a transverse direction substantially normal to said profile and substantially parallel to said base surface, and to, in other positions of said mobile, stop a feeler-spindle or a pin on a transverse surface of a first column of said plurality of columns, wherein at least said first column includes at least one intermediate transverse stopping surface which is arranged to constitute a stop bearing surface of one said feeler-spindle or one said pin and enable a partial insertion of one said feeler-spindle or one said pin in the thickness of one said slot, and which is located, in said transverse direction, between the geometric envelopes of two end transverse surfaces which transversely delimit said first column,
wherein each column of the plurality of columns that includes at least one said intermediate transverse stopping surface has a variable thickness in said transverse direction, and includes at least one projection arranged to retain said feeler-spindle or said pin of a clockwork mechanism arranged to cooperate with said selector mechanism, said projection including said intermediate stopping surface and a front stopping surface in the direction of said profile, and
wherein said profile is closed, and wherein said at least one projection is inside said mobile.

12. The selector mechanism according to claim 11 , wherein each said projection is inside said mobile.

13. A chronograph mechanism comprising:
at least one clockwork column selector mechanism, comprising a mobile including a plurality of columns protruding above a base surface and separated by clearances, said columns and said clearances together forming slots extending along a profile, arranged to, in certain positions of said mobile, enable the insertion of a feeler-spindle or a pin into one said clearance in a transverse direction substantially normal to said profile and substantially parallel to said base surface, and to, in other positions of said mobile, stop a feeler-spindle or a pin on a transverse surface of a first column of said plurality of columns, wherein at least said first column includes at least one intermediate transverse stopping surface which is arranged to constitute a stop bearing surface of one said feeler-spindle or one said pin and enable a partial insertion of one said feeler-spindle or one said pin in the thickness of one said slot, and which is located, in said transverse direction, between the geometric envelopes of two end transverse surfaces which transversely delimit said first column,
wherein each column of the plurality of columns that includes at least one said intermediate transverse stopping surface has a variable thickness in said transverse direction, and includes at least one projection arranged to retain said feeler-spindle or said pin of a clockwork mechanism arranged to cooperate with said selector mechanism, said projection including said intermediate stopping surface and a front stopping surface in the direction of said profile, and
wherein said chronograph mechanism includes a pin which is arranged to, according to the position of said mobile, in a start position corresponding to the running of the chronograph, remain at least partially in one said clearance between said two columns of said plurality of columns, or in a stop position corresponding to stopping the chronograph, cooperate in bearing engagement with one said projection, or in a reset position for resetting the chronograph, bear on an end transverse surface of one column of said plurality of columns.
