ABSTRACT:
A force transfer mechanism including a force lever through which an input force is transmitted to an output member with mechanical advantage only after the output member encounters sufficient resistance to overcome a friction connection between an input member and the output member indicative of the input member having moved from a retracted position to an operative position. The resultant movement of the input member relative to the output member in the absence of the frictional connection therebetween allows the input member to engage the end of force lever that is normally spaced-apart therefrom and to accordingly drive the output member with a force corresponding to the input force multiplied by the ratio of the force lever only in the operative position of the input member.
