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 façade system for buildings provides supports for glass having less surface area, whereby a more undisturbed view to the outside is provided. The equipping is conducted by fastening the used insulating transparent pane units in two steps. The weight of the used glass pane elements is supported by bearings that may be arranged at any position of at least one substantially horizontal or substantially vertical structure element. Due to their substantially horizontal or vertical alignment the bearings do not influence the size of the visible portion of the faced structure. To keep the panes tight on the building, pressure structure elements are mounted from the outside of the building to fasten the panes tight on the building structure or a carrying element of the building.

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.
