The invention relates to an articulated crank, e.g. for Venetian blinds or roller blinds, one end of which interacts with the Venetian blind or the roller blind, whereas the other end bears a central piece and a handle, the central piece being connected, both to the articulated crank and to the handle, via in each case one articulation, comprising two outer legs and a central leg, with a pin. The central leg and/or the outer legs each have a bearing sleeve which consists of a softer material than the pin, is fixedly connected to the legs and in which the pin is mounted. |
