Abstract:
A louvre blade assembly, comprising:a mullion with a plurality of openings;a plurality of control bars moveably mounted within the mullion;a plurality of louvre blade mounts, each louvre blade mount having a projection removeably coupled to at least one of said control bars, wherein each projection is mounted within a respective opening in the mullion so as to rotate about an axis of rotation;an operating handle operatively coupled to at least one of the plurality of control bars so as to be movable between a first position which corresponds to the louvre blade mounts being located in a closed position and a second position which corresponds to the louvre blade mounts being located in a fully open position;a releasable limit device in operative communication with the operating handle so as to prevent the operating handle from moving beyond the second position and to permit the operating handle to move to a third position; andat least one retainer in operative communication with each projection and the operating handle so as to retain each projection in that projection's associated opening in the mullion when the operating handle is in one of the first and second position and to permit axial withdrawal of each projection from that projection's associated opening when the operating handle is in the third position.
