US Patent 10900269 Actuating arm drive

An actuating arm drive for a pivotably mounted actuating arm, in particular for driving a flap of a piece of furniture, includes a plurality of articulatedly interconnected levers. A first lever and a second lever of the actuating arm drive are arranged parallel to one another with a lateral spacing, and the levers each have two axial bores with a first standard spacing, through each of which bores an axial pin projects. A third lever has receptacles for the axial pins with a second standard spacing, and the second standard spacing is different than the first standard spacing. The axial pins each project through the axial bores of the first and second lever and are at least partially received in the receptacles of the third lever.
