Abstract:
1. A handle assembly, comprising: a handle housing having a trigger movable in a first direction from a fully open position to a fully closed position, and a second direction from the fully closed position to the fully open position; and a pawl and ratchet disposed within the handle housing and operatively associated with the trigger, the pawl being pivotally disposed about a fixed pivot point with the housing and the ratchet having a notch positioned between a plurality of teeth and an end tooth; wherein, when the pawl is engaged with the plurality of teeth the ratchet limits movement of the trigger to the first direction, and when the pawl is disposed within the notch the ratchet allows the trigger to be selectively moved in both the first and second directions such that the trigger can move from a partially closed position directly to the fully open position without first being moved to the fully closed position.
