Coaxial double drive assembly applicable with shielding elements of a secondary skin facade of a building

A coaxial double drive assembly configured for actuating shielding elements of a secondary skin façade of a building, comprising

• an outer drive output and an inner drive output, which are arranged substantially coaxially with each other to an axis of rotation;
• a driving arrangement, which is adapted to accept one or more transmission gear assemblies, which connect the outer and inner drive output to one or more rotating motor drives, which axes of rotation are substantially perpendicular to the axis of rotation of the outer and inner drive outputs;
• a first gear wheel connected to the outer drive output and a second gear wheel connected to the inner drive output, wherein the first and second gear wheels pivot about the axis of rotation;
• and
• a first worm pinion engaging with the first gear wheel and a second worm pinion engaging with the second gear wheel,
• wherein the outer drive output and the inner drive output extend at the same side of the coaxial double drive assembly and are adapted to accept a two-part pivot assembly, which when pivoted by the outer drive output and the inner drive output, is adapted for actuating the shielding elements of the secondary skin facade coupled thereto,
• wherein the first worm pinion (20) and the second worm pinion (21) are connectable with driving rods (71, 71a, 71b, 71c), which allow for interconnecting the first worm pinions (20) of a drive interconnecting arrangement comprising two or more coaxial double drive assemblies (1) and which allow for interconnecting the second worm pinions (21) of the drive interconnecting arrangement,
• wherein the drive interconnecting arrangement comprises a first transmission gear assembly connectable with a first rotating motor drive, wherein the first transmission gear assembly mounted one of the coaxial double drive assemblies of the drive interconnecting arrangement interconnects the first motor drive with the first worm pinion,
• wherein the drive interconnecting arrangement comprises a second transmission gear assembly connectable with a second rotating motor drive, wherein the second transmission gear assembly mounted one of the coaxial double drive assemblies of the drive interconnecting arrangement interconnects the second motor drive with the second worm pinion.
