Definitions

the invention relates to a drive and transmission member for an escapement of a timepiece, said escapement comprising an escape wheel, an anchor and at least one a plate driven on a balance shaft, said drive and transmission member being intended firstly to rotate said anchor when it rotates with said plate and secondly to transmit a pulse of said anchor to said plate .
Said drive and transmission member comprises an elastic clamping means adapted to act in a clamping plane and intended to be arranged, in use, such that said clamping plane is substantially perpendicular to said balance shaft, and comprises a means of interaction extending from said clamping means and for interacting with said anchor to drive it.
a first embodiment of a drive and transmission member 10 having an elastic clamping means and an interaction means.
the elastic clamping means is in the form of a ring 20 having an axis 100, an inner face 22 and an outer face 32, and open by a slot 30.
a lug 40 extends radially from said outer face 32, diametrically opposite to the slot 30.
the slot 30 is axial. She could be oblique. The presence of the slot 30 imparts elasticity to the ring 20.
the lug 40 and the slot 30 define a first direction 11 of the drive and transmission member 10, which forms with the axis 100 of the ring 20 a plane of symmetry for the drive member and transmission 10.
FIG. 2 there is shown a second embodiment of a drive and transmission member 50, which differs from the first embodiment of the drive and transmission member 10 in that the lug 40 is provided with a through hole 54 extending in a second direction 12 which intersects the clamping plane of the ring 20.
the second direction 12 is parallel to the axis 100 of the ring 20.
the through hole 54 is disposed near the free end of the lug 40.
the contact between the inner face 22 and the balance shaft 2 is only on the three portions which are not not recessed, that is to say on the two portions 26 adjacent the slot 30 and the portion 28 diametrically opposite the slot 30.
Such arrangement in three contact zones improves the elastic clamping of the ring 20 on the balance shaft.
This second embodiment of the holding means is also compatible with a plate 60 according to the first embodiment, although such a variant is not shown in the figures for the sake of simplification.
the ring 20 is, in use, immobilized directly against the balance shaft 2 by the stud 6.
the plate 60, 70 is preferably made of metal, for example steel or nickel.
the plate 60, 70 and the pads 4, 4, 6 are made in one piece. More preferably, the pads 4, 4, 6 are obtained by galvanic growth by means of a process known as the LIGA process.
the exhaust 80 further comprises a plate 60 according to the first embodiment, driven on a balance shaft 2 and provided with a drive and transmission member 10 according to the first aspect of the invention, which comprises a ring 20 and a lug 40 immobilized on the plate 60 by two studs 4, 4 as described with reference to the figure 3 .
the balance shaft 2 rotates in the direction indicated by the arrow 200.
the plate 60 driven on the balance shaft 2, rotates in the same direction.
the drive and transmission member 10, immobilized on the plate 60 by means of the studs 4, 4, rotates with it, until it meets the one 844 of the horns 844, 846 of the fork 840 and causes it to rotate, thereby rotating the anchor 84 about the anchor axis 806.
one of the lifts 848 releases the tooth 822, which leaves turn the escape wheel 82.
the tooth 822 transmits a pulse from the escape wheel 82 to the anchor 84, which transmits it, via the drive member and 10, the plate 60 and the balance shaft 2 on which is driven said plate 60.
the lug 40 of the drive and transmission member 10 advantageously fulfills the conventional functions of the plateau pin of a conventional exhaust.
the invention is not limited to the embodiments that have been illustrated in the figures and covers alternative embodiments within the scope of those skilled in the art.
the end face 46 of the lug 40 of the drive and transmission member could be concave or convex instead of being flat.
the resilient clamping means could have a shape different from that of a split ring, and the clamping could be performed on two points instead of three points.
