The mechanism contains a RRR kinematic chain connected in parallel with a four bar linkage. The kinematic chain RRR´s joints are connected with the crank and the coupler of the four bar linkage. By means of changing the geometrical lengths of the mechanism´s links, the coupler point M describes a range of coupler curves.
