Abstract: A coaxial double drive assembly configured for actuating shielding elements of a secondary skin facade of a building is disclosed. The assembly includes an outer drive output and an inner drive output, which are arranged substantially coaxially with each other to an axis of rotation. The assembly also includes 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. 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.

Abstract: A coaxial double drive assembly, in particular to actuating shielding elements of a secondary skin facade of a building, is provided. The coaxial double drive assembly comprises an outer drive output and an inner drive output, which are arranged substantially coaxially with each other to an axis of rotation. The outer drive output and the inner drive output extend at the same side of the coaxial double drive assembly and accept a two-part pivot assembly, which when pivoted by the outer drive output and the inner drive output is adapted for orienting the shielding elements coupled thereto.
