Abstract:
The present application relates to a mechanism for selecting and actuating n functions of a clock movement, where n is an integer no lower than 1, preferably no lower than 2, more preferably no lower than 3, including a winding mechanism rod ending in a crown, a device for actuating a function, said device being kinematically connected to the crown and arranged such as to move and assume n selection positions and n actuation positions in which the actuation device is kinematically connected to an actuation member of the selected function, and a selecting device arranged such as to move the actuation device into a selection position. Said mechanism further includes a base onto which the actuation device is moveably mounted such as to be moved and positioned, by the selecting device, into a selection position facing the actuation member of the selected function, and such as to be moved, by an axial movement of the winding mechanism rod, into the actuation position thereof in order to engage with said actuation member of the selected function.
Abstract:
The device includes a support pipe driven into a bore of a watchcase, a push-piece crown consisting of a head and an extension mounted into the pipe in mobile manner, a part entraining rotation that is integral with the winding and setting stem of the watch, coupling elements causing the extension and the entraining part to move together in rotation as well as in translation in the direction of pulling, a first axial spring arranged between the crown's head and the entraining part, and a second axial spring arranged between the crown's head and the pipe. The first spring exerts a force that is high enough to overcome the resistance offered by stem during the change from the setting position to the winding position of the crown. The second spring exerts the principal restoring force bringing the crown back from its pushed position to its winding position.
Abstract:
The push-button mechanism includes a lever (11) which pivots on a plane support (2), and includes two other pins (14, 16) arranged in a triangle with respect to the stud (12), and a second member (20) including a substantially U shaped cut-out portion (21) delimiting a base (22), and first and second arms (28, 32). The base (22) supports guide means (23) which slide along a guide ramp (3) and at least one control means (24) for a function to be activated (5, 6). The first rigid arm (28) is rotatably mounted on a first pin (14) of the lever (11) and the second flexible arm (32) has at its free end (33) a notch (34) acting as support for the second pin (16) in the inactive position, said notch (34) being extended by a beak shaped tip (36) having an external edge (38) oriented towards the exterior of the U shaped cut-out portion (21) against which the second pin (16) slides compressing the flexible arm (32) and producing a clicking by passing from one position to the other.
Abstract:
A tuning fork of a timepiece is vibrationally driven by an electric circuit and a gear train transmits the vibratory motion of the tuning fork to a set of hands which indicate the time. A crown is mounted for pushing movement to a hands-running position and pulling movement to a hands-setting position and a power switch is opened during pulling movement of the crown to cut off the supply of power to the electric circuit and the power switch is closed during pushing movement of the crown to turn on the supply of power to the electric circuit. A pivotal lever is pivoted into engagement with the gear train during pulling movement of the crown to releasably lock the gear train against movement and the lever is pivoted out of engagement with the gear train to free same for movement during pushing movement of the crown. An impact member is mounted on the lever and strikes the tuning fork to start same into vibration during pivotal movement of the lever away from the gear train so that the tuning fork is mechanically set into vibration by the impact member and the vibrations are then sustained by the electric circuit.
Abstract:
A horological movement, such as an electrical or mechanical watch, has an elongated resilient spring which is secured to a base plate at one of its ends. The spring is operated by a stem and acts to bias a cock and also to selectively stop a balance wheel assembly.
