Disclosed is a winch, particularly for driving an umbrella, comprising a rope drum ( 48 a) which is driven by a hand crank ( 24 ) and winds up a rope ( 28 ). Functioning of the winch is improved by the fact that said winch is provided with a feeler ( 100 ) which responds to the direction of entry of the rope when the rope ( 28 ) is fully unwound or to the winding of the rope onto the rope drum ( 48 a). Said feeler ( 100 ) is connected to a locking member ( 102 ) that cooperates with a stop ( 104 ) if winding occurs in the wrong direction, said stop ( 104 ) being assigned to the rope drum ( 48 a) and locking the wrong winding direction.
