ABSTRACT:
A skylight, having a wing actuated by pneumatic springs, can be moved to an emergency opening position thereby substantially exposing the opening area of the skylight case. The skylight also acts as a residential ceiling or attic skylight which has, in the normal open position, a considerably smaller opening than in the emergency open position. A locking device is provided to restrict the long extension stroke of the piston rod of the pneumatic springs to a partial stroke. This partial stroke allows an opening which essentially corresponds to the standard opening of the wing in a residential skylight. The locking device, located on the cylinder of the pneumatic spring, includes a specially designed latch which, in order to effect partial stroke restriction of the piston rod, lockingly engages a stop located on the side of the case by means of a catch pin.
