Patent ID: 8562183

Claim:
An actuating assembly for beam processing members of a stage light fitting for generating a light beam; the actuating assembly ( 4 ) comprising a frame ( 7 ), at least a first and second beam processing member ( 22 , 24 ), drive means, and transmission means for transmitting motion to the first and second beam processing member ( 22 , 24 ) to selectively move the first and second beam processing member ( 22 , 24 ) between a first position of non-interference with the beam, and a second position of interference with the beam; the actuating assembly ( 4 ) being characterized in that-the drive means comprise a motor ( 42 ) having a shaft ( 41 ); and in that the transmission means connect the shaft ( 41 ) of the motor ( 42 ) to the first and second beam processing member ( 22 , 24 ) to selectively move the first and second beam processing member ( 22 , 24 ) successively, wherein the transmission means comprises: a first supporting structure ( 23 ) supporting the first beam processing member ( 22 ), which rotates about an axis of rotation (B 1 ); a second supporting structure ( 25 ) supporting the second beam processing member ( 24 ), which rotates about the axis of rotation (B 1 ); and at least one cam ( 40 ) fixed to the shaft ( 41 ) of the motor ( 42 ).
