Abstract

A housing for a laptop computer or computer terminal and the computer and terminal themselves in which opening the top causes a curved surface to descend below the computer's rear, bottom surface. This ridge runs across at least half of the bottom of the computer's back and preferably the entire computer. It serves to support the bottom section of the cover, and thus the keyboard, when used on a person's lap at a suitable angle. Specifically, it elevates the rear of the keyboard so that the hands have facile access to all the keys. The curved surface is formed integrally with the edge of the computer cover's upper section. When the top closes, the surface moves to a position where it does not descend below the bottom of the cover in order to provide a neat, portable package. Opening the top causes the surface, or ridge, to occupy the position where it will sit on the person's legs to prop up the keyboard.
