ABSTRACT:
An improved skylight blind for mounting in the light well of a skylight. The blind has a frame which defines a substantially rectangular opening through which visible light transmitted through the skylight can pass in order to enter the interior of a structure in which the skylight is incorporated. Slats are mounted on the frame so that when closed light is substantially not transmitted through the blind and when open the slats of the blind present a minimum of obstructions to such light. A motor plus controls opens and closes the blinds in response to manual controls or temperature and light sensitive controls. The slats and motor are enclosed between two planar sheets of an impact resistant and transparent material which planar sheets are secured to the frame to form an enclosure. The blind inhibits the use of the skylight as an unauthorized entry into the interior of a structure in which the skylight is mounted, while the impact resistant and transparent material provide significantly enhanced impediment to physical intrusion of the structure.
