Patent ID: 7307764

Claim:
An apparatus for shifting a movable platen between a resting position and an actuated position, the apparatus comprising: (a) means for suspending said movable platen from a stationary housing to allow movement of said movable platen between said resting and said actuated positions; (b) a lever member pivoted at a flexure element, said flexure element being coupled to said stationary housing, the position of said flexure element along said lever member defining: (i) a working arm of said lever member between said flexure element and the movable platen; and (ii) an effort arm of said lever member between said flexure element and the point of contact of an actuator; and said effort arm driven by said actuator to shift said movable platen from said resting position to said actuated position, such that the travel distance of said movable platen between said resting position and said actuated position is proportional to the ratio of the length of said working arm to the length of said effort arm.
