Abstract

The invention concerns a hinged, swinging skylight in which the sash can rotate and is carried by two arms arranged so they can swivel on the upper end of the casement. The sash is held in the swinging position by spindles that seat in grooves or channels on the side members of the casement and can move therein. In the hinged position, the sash is tightly connected to the arms. To increase comfort and improve operability, the grooves have no limits for the upper ends and the spindles are able to move longitudinally along the side rails of the sash by activating a handle in such a way that they are in the grooves in the swinging position and outside the grooves in the hinged position. At the same time, coupling elements are activated by the handle and are connected tightly to the arms in the hinged position of the sash, and this connection is released in the swinging position.
