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.
