Abstract
Abstract A latch handle assembly for securing a latch having a trigger pin includes a handle pivotally joined to the latch. A trigger latch is pivotally joined to the handle and includes an opening engageable onto the trigger pin. A cam is pivotally joined to the handle and is engageable onto the trigger pin to compensate for any clearances between the parts, and thereby prevent chattering and excessive wear within the handle assembly due to vibration.
