Abstract
Abstract The window comprises a rectangular casing and a leaf mounted on a frame and can be caused to pivot about an axis located at the vertical leaf edge or about an axis located at the bottom horizontal leaf edge. The window is provided at one corner with a support comprising a vertical pivot-pin and a horizontal pivotpin, a link-rod system disposed along the two sides of the window which do not serve as an axis of rotation, the displacements of said system being such as to create one point of pivotal motion and to release the other in alternate sequence. The link-rod system is coupled to a cam having a surface applied in contact with said system so as to displace this latter over certain parts of the cam contour while permitting the system to remain motionless over other parts of the contour.
