Abstract:
A shock absorber spring (1) for a timepiece (200), extending substantially in a plane (P1) and having a first axis of symmetry (A1) perpendicular to the plane (P1), the spring including at least two first spring-fixing elements (11, 11′, 11″), these first fixing elements each comprising at least a first fixing surface (11a, 11b, 11a′, 11b′, 11a″, 11b″) oriented at least substantially radially relative to the first axis (A1) and towards the first axis (A1).
Abstract:
The assembly device is intended for the pivoting attachment of at least two components (M1, M2). It comprises a screw (4) intended to be screwed into a first component (M1) and bearing a guide pin (5) guiding the pivoting of a second component (M2). According to the invention, the pin (5) comprises at least one rotation-prevention zone (540) having a shape designed to collaborate with a zone of corresponding shape of the first component (M1), so as to prevent said pin from rotating.
Abstract:
Timepiece driving device (100), in particular for an instantaneous jump calendar system, the device including; an input mobile (13); a main cam (11) having a main cam profile, and connected to the input mobile either (i) with angular backlash or (ii) via a unidirectional coupling; an auxiliary cam (12) connected to the input mobile, and having an auxiliary cam profile; a cam follower (21) adapted to cooperate with the main cam profile and/or with the auxiliary cam profile; and an energy accumulator (22) elastically biasing the cam follower toward the main cam profile and toward the auxiliary cam profile, the timepiece driving device (100) being arranged so that the cam follower (21) comes substantially into contact with the auxiliary cam profile immediately at the end of the driving of the main cam (11) by action of the energy accumulator (22) on the main cam (11) via the cam follower (21).
