Patent ID: 6856763

Claim:
A hand-held device having a deployable component, said device comprising: a body; a deployable component mounted to said body, said deployable component being movable between opposed undeployed and deployed positions; a drive unit disposed within said body, said drive unit engaging said deployable component, said drive unit being reversibly pivotable about a drive axis from a first end orientation, through a first range of intermediate orientations, then through a second range of intermediate orientations, to a second end orientation; an actuator mounted to said body, said actuator being manually switchable, in a forward stroke from a primary position to a secondary position, and, in a rearward stroke from said secondary position to said primary position, said actuator at said forward stroke pivoting said drive unit from said first end orientation to an intermediate orientation in said second range, said actuator at said rearward stroke pivoting said drive unit from said second end orientation to an intermediate orientation in said first range; a drive over-center mechanism biasing said drive unit to pivot from said intermediate orientations in said second range toward said second end orientation, when said actuator at said forward stroke has pivoted said drive unit and from said first end orientation to an intermediate orientation in said second range, and from said intermediate orientations in said first range toward said first end orientation, when said actuator at said rearward stroke has pivoted said drive unit and from said second end orientation to an intermediate orientation in said second range.
