Abstract: A sectional door for controlling the access opening to a compartment, includes a fixed portion including two pairs of vertical guides extending in a direction substantially parallel to a respective shoulder of the opening; and a movable portion including a leaf having a lower panel and an upper surrounding panel, extending over the entire width of the leaf and having its lateral sides in sliding engagement along a respective side guide, a pair of side support arms each having one end thereof articulated in correspondence to the top of a respective pair of vertical guides and the other end thereof pivoted in correspondence to an intermediate zone of a respective lateral side of the upper panel, and articulated and slidable connection elements between the lower panel and the upper panel, whereby the lower and upper panels are movable between a closed, and an open position.

Abstract: A driving and guiding apparatus for a counter-weighed horizontally pivoted wing, particularly for a garage door. The apparatus comprises a structure embedded in an opening that the wing is designed to close, two lateral vertical guides for the wing formed in the embedded structure, an articulation rod on each side and two lateral weight-carrying cables turning around a respective pulley. The apparatus also comprises a drive means for opening and closing the wing which includes a motor-driven transmission shaft which extends along the lintel of the opening in which the wing is mounted, a pinion mounted on each end of the transmission shaft and a toothed wheel mounted coaxially and rigid in rotation with each pulley. Each toothed wheel meshes with a respective pinion so that the rotation of the transmission shaft in one direction causes controlled unwinding of the cables, and thus the opening or lifting of the wing, and its rotation in the opposite direction causes its shutting or lowering.
