Abstract

The invention relates to a jumper (30, 40) for a timepiece movement (10), said jumper being of the type that comprises a base (42) and an elastically deformable arm (80) extending from said base (42) and provided with an abutment surface (82) for co-operating with a notch of a mobile element (222, 242). The base (42) comprises a supporting element (52) carrying said arm (80). It comprises two connection elements (54, 56) each connecting an end of the supporting element (52) to a fixed element (420) of the base (42). The jumper (30, 40) is associated with a control body (86) arranged such that an axial rotation of said control body (86) causes a displacement of said supporting element (52) by deformation of a frame (55), the sides of which are formed by the supporting element (52) and two connecting elements (54, 56).

Abstract

The invention relates to an instantaneous driving mechanism for a timepiece movement, comprising a pivoting mobile element (2) and lever (6), the lever being arranged in such a way as to co-operate with the mobile element in order to be moved, and with a counter (8, 13) of the timepiece, in order to increment it by means of instantaneous impulses. The mobile element (2) comprises a first cam (28) having a variable radial periphery, said cam being arranged so as to cooperate with the first arm (7) of the lever and to progressively move it away from the centre of the mobile element (2) when said mobile element rotates in a first rotational direction, before making it fall, under the effect of the action of elastic means (22). The mechanism is characterised by the fact that the mobile element (2) comprises a safety body (38) arranged so as to cooperate with the lever (6) in order to move it away from the centre of the mobile element when said mobile element rotates in the second rotational direction.

Abstract

The invention relates to a support (20) for a mechanism for displaying jumping-type information for a timepiece movement and comprising a display body (54) to be rotated by means of a driving star (14), the support (20) to be positioned between the display element and a frame element of the timepiece movement. The support comprises a base (22) that has at least one first hole (26) for receiving a shaft (60) for rotating the display body, and from which extend a first arm (30) arranged in such a way as to be able to ensure the function of a jumper for the driving star (14), and a second arm (32) arranged in such a way as to be able to act on the driving star (14) so as to be able to make it turn in order to correct the information to be displayed in response to a pre-defined action of a user aiming to deform the second arm (32).

Abstract

The invention relates to an actuating mechanism comprising a first mobile element (1) comprising two toothings (10, 12), one for enabling the driving of the first mobile element and the other for driving a second mobile element (3) arranged so as to pivot, under the effect of the action of an elastic body (34), between an idle position and at least one actuating position, in which it can act on an additional mechanism (40, 64).

Abstract

The invention relates to a display mechanism for displaying the calendar number in the form of a large date, for a timepiece movement, comprising first and second concentric disks (19, 18) respectively displaying tens of calendar numbers and units of calendar numbers, the first disk (19) having a diameter larger than that of the second disk (18), the first and second disks being respectively secured to the first and second stars (16, 15) that each have a toothing. The mechanism also comprises a programmed wheel (14) arranged so as to rotate the first and second stars (16, 15), said wheel carrying first and second outer toothings (34, 32) arranged so as to cooperate respectively, at least indirectly, with the first and second stars (16, 15), the first toothing (34) having a diameter smaller than that of the second toothing (32).
