<p>The mechanism comprises a first spindle supported in a prismatic box-like body, having at one end thereof a toothed wheel. Fitted to the spindle with the interposition of resilient biasing means, is a hollow cylindrical element having a circumferential ring of projecting teeth. The toothed wheel of the spindle engages a cooperating toothed wheel carried at an end of a second spindle which also has a support hook for one of the strips of a vertical strip blind. The body is housed, with the spindle disposed on one side thereof, in a sliding track provided with opposite guides for the passage of a flexible control member, this latter being engagable with the toothed circumferential projection formed on the hollow cylindrical element which surrounds the first spindle.</p> |
