Wall or door made from foldable elements - has mechanism ensuring closing by temperature rise due to fire

摘要

Partition wall or door is made especially from foldable elements, designed so that they are automatically moved in special critical situations, especially in case of fire, into closed position. The wall arrangement has automatically acting closing arrangement (19) which responds to a temp. increase caused e.g. by fire or fumes. This wall can be operated also independently from the automatic closing arrangement, which is in its initial position loaded in closing direction of the wall or door. The arrangement has pressure sensitive element built from preloaded flexible compression or tension springs actuating a linkage in closing direction.
