MODULAR SHUTTER FOR WINDOWS OR THE LIKE ABSTRACT OF THE DISCLOSURE A modular shutter which is assembled of prefabricated components and of yard goods or piece goods which are cut to size at the locale of use. The components of the shutter include two upright guide rails for the end portions of a curtain of upwardly and downwardly movable as well as tiltable slats, a horizontal main shaft between the upper end portions of the guide rails, a housing mounted on top of each guide rail and having bearings for the corresponding end portions of the main shaft, a motor or a crank drive for rotating the main shaft clockwise or counter- clockwise, and combined lifting and tilting mechanisms in the housings. Such mechanisms have lifting bands which are connected with the end portions of the slats to effect upward or downward movements of the slats in response to rotation of the main shaft in one or the other direction, and tilting bands which change the angular positions of the slats in response to selected stages of angular movement of the main shaft.
