Abstract
Abstract A protective case for housing a portable computer having a keyboard and a display, which protective case includes a keyboard case for receiving the keyboard and a display case for receiving the display. The display case is pivotally attached to the keyboard case and is movable between an open position and a closed position relative to the keyboard case. The axis of rotation of the display case relative to the keyboard case is coaxial with the axis of rotation of the display relative to the keyboard of the portable computer. An articulating handle is provided which attaches to both the keyboard case and the display case, and articulates about a pivot pin as the display case moves relative to the keyboard case. Additionally, the handle may be moved between an unlatched position whereby the display case pivots freely relative to the keyboard case, and a latched position whereby the display case is retained against movement relative to the keyboard case. In the unlatched position, the handle articulates about a pivot pin which is parallel to the axis of rotation of the portable computer. In the latched position, the pivot pin is substantially perpendicular to the axis of rotation of the portable computer thereby preventing movement of the display relative to the keyboard.
