  • Publication number: 20080030942
    Abstract: A folding electronic device includes first and second housing bodies mounted for pivotal movement relative to each other between first and second configurations. At least one hollow flexible elastic hinge has first and second ends fixedly attached to the first and second bodies, respectively. Each hinge expands as the bodies pivot toward the first configuration and contracts as the bodies pivot toward the second configuration. In accordance with the preferred embodiments, the hinges comprise a pair of elastic fabric tubes advantageously having near-zero tolerance, and a flexible wiring ribbon extends through each tube and is free to slide therein as the tube expands and contracts. Also in accordance with the preferred embodiments, user controls on the first body and a display screen on the second body are exposed in an open configuration and covered in a closed configuration, and in both configurations the bodies are oriented and secured wall-to-wall.
