Clockwork selector mechanism

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.

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.
