Abstract: A skylight has a sash, a casement and [spring-loaded.revreaction. carrier arms which are mounted at one end to the casement and at the other end on a pivot bearing on the sash side rail. The sash has spindles cooperating with a U-shaped runner on the side member of the casement. A cover plate borders the channel of the runner and overlaps the spindles when the sash is in the swinging position. When the sash is in the closed position [and the swinging position], the spindles is outside the working range of the cover plate. When the sash is opened and the carrier arm is coupled thereto, it tilts on the pivot bearing. When opened with the sash uncoupled from the carrier arms, the spindle move in the grooves of the runner toward the lower edge of the casement, and the pivot bearing on the casement is lifted off and the sash swings open. The spindles are positioned on the side rail of the sash and move longitudinally when they are seated in individual settings by movement of the handle on the sash cross member.

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.
