Abstract:
1. A rolling shutter assembly for covering an opening of a structure, comprising: a shutter housing mounted at the top of the opening and having a throw member opening; a shutter support member mounted within the shutter housing; a shutter curtain connected to the shutter support member at a top edge of the shutter curtain, the shutter curtain having a base slat connected to a bottom edge of the shutter curtain, wherein the shutter curtain is rolled up onto the shutter support member when the shutter support member rotates in a first direction and is unrolled from the shutter support member when the shutter support member rotates in a second direction; a pair of side tracks mounted on opposite sides of the opening and receiving corresponding ends of the shutter curtain when the shutter curtain is unrolled; a drive motor coupled to the shutter support member to rotate the shutter support member in both the first direction and the second direction; a limit switch operatively connected to the drive motor and disposed within the shutter housing, the limit switch having a normal position allowing the drive motor to be actuated to rotate in the first direction and an actuated position preventing the drive motor from being actuated to rotate in the first direction; and a throw member disposed within the shutter housing, the throw member comprising: a plunger operatively connected to one of the base slat and the throw member and operatively engaging the other of the base slat and the throw member when at least a portion of the base slat is disposed within the shutter housing to cause the throw member bolt to move against the biasing force of the biasing member to a position to turn off the drive motor when the base slat is raised to a predetermined position within the shutter housing, wherein the biasing member provides a force moving the base slat downward in the side tracks when the shutter curtain is unrolled from the predetermined position of the base slat within the shutter housing.
