Abstract
The present invention generally relates to a handle assembly for a hand operable bar clamp having a fixed jaw, a movable jaw and a drive for translating the movable jaw towards the fixed jaw. The assembly includes a handgrip and a trigger handle. The handgrip having an elongated rear portion has a generally rounded surface and being contoured to complement the natural transverse curve pf a human palm. The trigger handle is pivotal with respect to the handgrip. The trigger handle included an elongated front portion having a rounded front surface and being contoured to complement the natural palmer curve of a set of fingers flexed toward the palm. The shape and contour of the handle assembly cause pressure to be safely distributed across the user's hand when the handgrip and the trigger handle are grasped and the trigger handle is depressed toward said handgrip.
