Abstract
Transmission device (100), for example for a watch mechanism (110), in particular for a winding train (100, 201) of a watch movement (120), including an input element (6) intended to be driven only in a first direction, an output element, a first mechanical connection arranged such that the displacement of the input element in a first direction causes the displacement of the output element in a second direction, and a second mechanical connection (9′, 9) arranged such that the displacement of the input element in the first direction causes the displacement of the output element in a third direction, the third direction being opposite the second direction.
Claims20
A winding mechanism for a watch movement, comprising a barrel and a winding train, the winding train comprising a transmission device, the mechanism comprising a source of energy, the transmission device, comprising:
- an input element intended to be driven only in a first direction,
- an output element,
- a first mechanical connection arranged so that the displacement of the input element in the first direction causes the displacement of the output element in a second direction, and
- a second mechanical connection arranged so that the displacement of the input element in the first direction causes the displacement of the output element in a third direction, the third direction being opposite the second direction.
A transmission device for a winding train of a watch movement, comprising:
- an input element intended to be driven only in a first direction,
- an output element,
- a first mechanical connection arranged so that the displacement of the input element in the first direction causes the displacement of the output element in a second direction, and
- a second mechanical connection arranged so that the displacement of the input element in the first direction causes the displacement of the output element in a third direction, the third direction being opposite the second direction,
- wherein the second mechanical connection comprises:
- a frame comprising a first toothing,
- a wheel comprising a second toothing intended to engage with the first toothing,
- an Oldham coupling mechanically connecting the wheel and the output element,
- a cam profile, and
- a finger.
