ROLLING SHUTTER LOCKING SYSTEM
A locking system for a rolling shutter that includes a plurality of rolling shutter slats, comprises a guide track with a U-shaped guide channel having a channel base, and first and second channel walls. A lock bar is coupled to the rolling shutter slats. In a locked position, the lock bar extends transverse to the channel base. The lock bar has a notch covered by a breakaway wall that is aligned with the channel base in the locked position. The lock bar may be slidably received in a sleeve that is positioned in the guide channel to increase resistance to torsional forces on the locking system. In an alternative embodiment, the locking system comprises a unitary extruded body, a lock bar, and a handle. A longitudinal channel is formed integrally in the body for receiving the lock bar and handle. The lock bar is slidable in the channel between an extended locked position and a retracted unlocked position. The handle is positioned in the channel to stop the retraction of the lock bar at the unlocked position.
