Organ for elastically holding a timepiece component on a support element
An elastic holding organ for fastening a timepiece component on a support element, including a rigid portion provided with an inner face including at least three deformable arms provided with free ends defining an opening into which the support element can be inserted, the arms being configured to perform a coupling with the support element by an elastic clamping in compression of this support element in the opening.
Mechanical braking device for a horological mobile component
A braking device (100), separate and remote from its guide members, having resilient strips (3; 31; 32) borne by a braking mobile component (10) trapped between a structure (1) and a bolt (6) and movable perpendicularly to the axis of a horological mobile component arbor (30), on which the strips bear, and either all of the bearing forces on the arbor (30) of the strips (3) are exerted within a single angular sector having a centre angle (a) of less than 180°, or, opposite a first straight or convex strip (31) tangentially braking this arbor (30), a second strip (32) allows for relative mobility between the braking mobile component (10) and this arbor (30) in a direction of mobility (DM), the latter being: either parallel to the first resilient strip (31), or wavy and deformable perpendicularly to the direction of mobility (DM).
Timepiece
A timepiece includes an inner rotating ring including a plurality of teeth portions; a driving crown including a head portion and a shaft portion; and a driving wheel including a hole portion engageable with and disengageable from the shaft portion, and configured to mesh with the teeth portions. The hole portion includes a plurality of protruding portions disposed at intervals of an angle smaller than 90° and protruding toward a rotation axis of the shaft portion.
Timepiece display mechanism with a resilient hand
A timepiece display mechanism with a resilient hand including a first and second device for driving, about an output axis, a first and a second pipe mounted at the ends of a flexible strip, and including a display index distant from the pipes, these drive devices being arranged to deform the flexible strip, by varying the angular position of one pipe with respect to the other about the output axis, and to vary the radial position of the display index with respect to this axis, this mechanism includes a first differential on the drive train of the first pipe, one input of which is formed by a first cam, and a second differential on the drive train of the second pipe, one input of which is formed by a second cam.
TIMEPIECE DISPLAY MECHANISM
A timepiece display mechanism includes at least one display having a shaft, and having at least one plate and/or a bridge carrying at least one guide device for carrying and guiding this shaft around an axis, including, on a first side of said axis, a support surface comprising a V-shape or a pad, symmetrical with respect to a bisector plane passing through the axis, to centre the axis of the shaft on this bisector plane, and on a second opposite side, at least one holding element substantially diametrically opposite the support surface, all the holding elements exerting on this shaft a resultant elastic return force directed towards the axis, and preventing any radial exit of this shaft out of the guide bearing which is a platform with two parallel faces.
BRAKE SPRING FOR SUPPORTING ARBOR OF A DISPLAY, HOROLOGICAL MOVEMENT COMPRISING SAID BRAKE SPRING AND METHOD FOR INSTALLING SAID BRAKE SPRING
A brake spring intended to apply a radial force against a supporting arbor of a display of a watch, including an elastic strip, an elastic casing organ adapted to be fastened to an attachment organ of a structure of a horological movement, and a retaining element of the elastic strip configured to cooperate with the elastic strip, so as to hold it in a first position, the elastic strip being capable of being released from the retaining element so as to occupy a second position under the effect of an elastic return force, wherein it is capable of applying a resulting radial force against the arbor.
Timepiece display mobile component with friction adjustment mechanism
Timepiece display mobile component (1) comprising at least one resilient strip (4) returned to a display axis (DA), to cooperate in a friction drive with an arbor (2) of a drive mobile component (3) of a movement (100) or a mechanism, about the axis (DA), this mobile component (1) includes a flange (5) comprising, facing each resilient strip (4), an aperture (6) for the insertion and guidance of a manual or robotic tool to allow the tool to move the resilient strip (4) away from its rest position, and to insert the mobile component (1) on an arbor (2) when the resilient strip (4) is sufficiently far away to allow this mobile component to pass, and to ensure a constant friction value of all the resilient strips (4) on the arbor (2) when they are in frictional cooperation with the arbor (2) and when the tool is no longer in contact with the resilient strips (4).
