Actuating striker for opening shutter blade retracted to permit shutter closing and/or re-cocking of striker

A shutter mechanism comprising a shutter blade supported to move open and closed, a shutter actuator having an actuating striker and supported for a unidirectional movement to cause said actuating striker to strike said shutter blade to move the shutter blade open, and a closing spring for moving said shutter blade closed, is characterized in that:

• said shutter actuator is supported to be translated during its unidirectional movement to translate said actuating striker to strike said shutter blade to move the shutter blade open and is supported to be pivoted during a different direction of movement to move said actuating striker out of the way of said shutter blade to permit said shutter blade to be moved closed;
• and
• a guide device controls movement of said shutter actuator to effect the translation and the pivoting of said shutter actuator.

A shutter mechanism comprising a shutter blade supported to move open, and a shutter actuator having an actuating striker and supported for movement to cause said actuating striker to strike said shutter blade to move the shutter blade open and for movement to be re-cocked, is characterized in that:

• said shutter actuator is supported to be translated to translate said actuating striker in contact with said shutter blade to move the shutter blade open and is supported to be pivoted to retract said actuating striker away from said shutter blade to prevent said shutter blade from obstructing said actuating striker when said shutter actuator is re-cocked.
