Abstract
An assembly for covering a building opening that provides a shaft positioned at one end of the building opening, a curtain carried by the shaft, and a locking mechanism at the opposed end of the building opening from the shaft that selectively holds the curtain in a locked position to cover the building opening. The assembly also includes an input for selectively rotating the shaft, and a linking assembly adapted to transfer the input to the shaft to selectively rotate the shaft, wherein the linking assembly includes a failsafe portion designed to fail upon a predetermined impact force on the curtain. An operator is also provided to allow controllable movement of the curtain between the various positions.
