Abstract

A two-directional manual drive which produces a rotational movement, starting from the neutral position of a drive lever which can pivot around a drive axis whereby the rotational movement can occur in a selective manner in one of two rotational directions, includes a driven element having a driving surface, on which bearing surfaces of coupling elements are placed in frictional engagement when the drive lever is rotated out of a neutral position, displacing the driven element in the direction of the periphery. When the drive lever is returned to the neutral position the coupling elements are released from a position of frictional engagement with respect to the cylindrical driving surface so that the driven element is no longer displaced.
