A storage unit having a frame, drawers and a carrying handle. When the unit is lifted by the handle, or the handle is moved to a position suitable for lifting the storage unit, the handle arms lift the bottom drawer of the stack of drawers which in turn lifts each of the above drawers relative to the frame. As each drawer rises, the clearance gap between adjacent drawers is reduced and the drawers are moved to a locked position where they are blocked by detents mounted on the inside of the frame. In an alternative embodiment (not shown), the handle is coupled to drawer locking slides instead of the bottom drawer and detents on the drawer locking slides engage with the drawers to lock them in the closed position as the drawer locking slides are moved relative to the frame.
