Abstract:
A multi-function actuator, comprising:a first mechanism capable of bi-directional displacement; a motor operatively arranged to selectively displace said first mechanism through a first displacement range; a second mechanism capable of uni-directional displacement from a first position to a second position; a spring operatively arranged to urge said second mechanism to move from said first position to said second position; a release mechanism operatively arranged to release said spring when said first mechanism is moved beyond said first displacement range; a third mechanism capable of bi-directional displacement; and a clutch operated by the release of said spring to selectively disconnect said motor from said first mechanism and to selectively connect said motor to said third mechanism; whereby said motor may be operated to sequentially control the displacement of said first mechanism, the displacement of said second mechanism, and the displacement of said third mechanism.
