  • Security locking of rolling shutters
    Patent number: 3970134
    Abstract: A rolling shutter for building wall openings, has extra-long locking slats connecting the usual shutter slats to the slat storing roller. Lock slat guide blocks located adjacent the roller and outboard of the shutter slats cooperate with the lock slats when the shutter is closed to preclude disarrangement of the lock slats by a shutter opening force externally applied to the shutter slats, when the roller is locked.
