Abstract: An improved shutter system for covering an opening in a wall of a building provides a barrier assembly that reduces likelihood of slat dislodgement. The shutter system includes a mounting assembly having at least one pair of guide tracks, and a barrier assembly having a plurality of interlocking flexible slats and at least one slat retention plug. The slat retention plug is retainingly engaged to an end of one of the slats of the barrier assembly by at least one retention tab in a wall of one of the slats. The slat retention plug is adapted to be slidingly engaged within one of guide channels of inner surfaces of the guide tracks. The slat retention plug defines a shoulder engaging at least one stop member of at least one of inner surfaces of the guide tracks upon deflection of the slats.

Abstract: A shutter system for covering a wall opening includes a mounting assembly and a retractable/deployable barrier assembly. The mounting assembly includes at least one pair of guide tracks that are mountable on opposing sides of the opening. Each guide track includes inner surfaces that define a guide channel. Two of the inner surfaces oppose one another and at least one of such surfaces includes a protruding member that extends into the guide channel and angles away from an open end thereof. The barrier assembly includes a series of interlocking slats, some or all of which define angled recesses constructed to accommodate unobstructed passage of the slats in the guide channel during deployment and retraction. The recesses in the slats are further constructed to enable the slats to engage the protruding members of the guide tracks in the event that the slats are deflected due to exertion of a displacement force.
