Abstract
A shutter assembly which requires minimal storing space substantially comprises a) a plurality of transparent or glass slats which form a shutter by being vertically suspended one after another, b) a storage case storing the slats in a stacked condition, the storage case being mounted on an upper part of an entrance of a building, c) a plurality of slat connecting devices each of which perpendicularly connects the bottom end of any succeeding slat to the upper end of any preceding slat, and d) brake means for applying braking force onto any one of the slats for enabling the shutter to stop at any desired height from the floor of the building. Accordingly, the shutter can be automatically stopped at any desired position from the ground or floor level thus assuring the safety of the user.
