Abstract: A multiply pivoted folding computer housing structure is disclosed which may be deployed in a generally Z-shaped configuration (“Z-computer”) applicable to portable computers as well as other computer-user interface systems such as laptop, notebook and desktop personal computers, checkout scanners, video and communication devices such as cell phones, TV and digital video players. The preferred embodiment of the Z-computer of the invention comprises at least three separate panels: a low profile keyboard base panel which supports at its back end an upright CPU panel, which in turn supports at its upper edge an elevated flat panel display. These panels are interconnected by two hinge systems and are adjustably securable by means of a lock mechanism to an improved ergonomic deployed configuration with the display at a better viewing angle.
