Beidseitig wirkender manueller Antrieb

摘要

The present invention relates to a two-directional manual drive that produces a rotational movement, starting from the neutral position of a drive lever (1) that can pivot around a drive axis (20), whereby said rotational movement can occur in a selective manner in one of two rotational directions. A driven element (4) pertaining to said drive comprises a driving surface (40) on which bearing surfaces (51; 51'; 61, 61') of coupling elements are placed in non-positive fit when the drive lever (1) is rotated out of a neutral position, displacing the driven element (4) in the direction of the periphery. When the drive lever (1) is returned to a neutral position, the coupling elements (5, 6) are released from a position of non-positive fit with respect to the cylindrical driving surface (40) and the driven element (4) is no longer displaced.
