Abstract

Drive device (1) for a clockwork mechanism, comprising a drive member (2) mounted so as to be rotatable about an axis of rotation (10) and configured to drive a clockwork mechanism, the drive member (2) comprising a plurality of bearing surfaces (21), a first transmission member (3) movable from a first position of the first transmission member (3) to a second position of the first transmission member (3) and from the second position of the first transmission member (3) to the first position of the first transmission member (3), a second transmission member (4) movable from a first position of the second transmission member (4) to a second position of the second transmission member (4) and from the second position of the second transmission member (4) to the first position of the second transmission member (4), each transmission member (3; 4) being configured such that, during its movement from its second position to its first position, it drives the drive member (2) in rotation by cooperation with a bearing surface (21) of the plurality of bearing surfaces (21), the second transmission member (4) being configured so as not to block the rotation of the drive device (2) when the first transmission member (3) is driving the drive member (2), and the first transmission member (3) being configured so as not to block the rotation of the drive member (2) when the second transmission member (4) is driving the drive member (2). Timepiece comprising a timepiece movement and such a drive device, in which the first transmission member is moved from its first position to its second position by the timepiece movement, and the second transmission member is configured to be moved from its first position to its second position by a manual control mechanism.

Abstract

The device for coordinated actuation of two functions of a timepiece comprises one or more cams (7; 51, 53) arranged to be driven by the movement of the timepiece, and the respective profile or profiles of which each comprise(s) a discontinuity (9; 52, 54); and a first transmission member (11a, 11b; 49, 61) and a second transmission member (13a, 13b; 63) each comprising a cam follower (11a, 13a; 61, 64), the cam follower (11a; 61) of the first transmission member being arranged to cooperate with the profile of the cam (7) or of a first (51) of the cams (51, 53) and to periodically drop into the discontinuity (9; 52) of the profile of the cam (7) or of the first (51) of the cams (51, 53), the cam follower (13a; 64) of the second transmission member being arranged to cooperate with the profile of the cam (7) or of a second (53) of the cams (51, 53) and to periodically drop, with the same period as the drops of the cam follower (11a; 61) of the first transmission member, into the discontinuity (9; 54) of the profile of the cam (7) or of the second (53) of the cams (51, 53), the drops of the cam follower (11a; 61) of the first transmission member being temporally offset with respect to those of the cam follower (13a; 64) of the second transmission member.

Abstract

The invention relates to a decorative element comprising a number of stones (4) assembled in a closed frame (2) to form two decorative faces, the stones comprising two opposite external faces (10, 12), which are decorative, and internal faces serving as joins (20, 22) between these stones, and as edging (24, 26) with the interior contour of the frame (32), some of these internal faces (22, 24) having grooves (28) arranged inside the volume of the frame (2) and accepting strips (34) the ends of which cross the contour of this frame at two opposing points in order to be secured. According to the invention, said decorative element is characterized in that the interior contour (32) of the frame (2) has a protruding cross section which fits into corresponding channels made in the internal edging faces (24, 26) of the stones (4). Applicable for example to the creation of jewellery.
