A window structure having several ways of opening, said window structure (1) being substantially rectangular and comprising a sash (2) and a frame (3), in which opposite members of the sash (2) and the frame (3) are mutually connected at at least three sides of the window, in which said connection between the sash (2) and the frame (3) at each of said at least three sides comprises at least one motor driven operator device (4) comprising an operating member (5) connected with the sash (2) and the frame (3), said operating member having an associated motor driven operator (6) for advancing the operating member (5) substantially perpendicularly to the plane of the window, each operator devcie (4) comprising means preventing displacement of the sash (2) in the plane of the window but allowing pivoting of the sash (2) relative to the frame (3) about two substantially orthogonal axes, means for coordinated control of the operators of the operating members being designed in such a manner that opening of the window is allowed, both by parallel displacement of the sash (2) perpendicular to the plane of the window and by pivoting of the sash (2) about any pivot axis along one of the sides of the window under mutual coordination of the respective advancing positions of the operating members. |
