Support structure for portable electronic device

Abstract

Disclosed herein are structures for supporting a clamshell- or slider-type portable electronic device such as a notebook computer; personal digital assistant; or wireless telephone. The clamshell- and slider-type portable electronic devices typically have at least two assemblies—a first housing assembly, and a second housing assembly containing at least a keyboard. In a clamshell-type electronic device, the first housing assembly and second housing assembly are connected by a hinge and pivot between at least an open position and a closed position. In a slider-type electronic device, the first housing assembly and second housing assembly are connected by a slide connection and slide between at least an open position and a closed position. In portable electronic devices made in accordance with the invention, the keyboard is comprised of a first set of keys and a second set of keys. The keys comprising the first and second sets have touch surfaces configured to receive keystrokes. The touch surfaces of the first set of keys extend above the touch surfaces of the second set of keys. When a portable electronic device having either the clamshell- or slider-type configuration is in a closed position, the combination of the varying heights of the touch surfaces of the keys and cooperating structures in the first and second housings hinders relative movement between the first and second housing assemblies when an external force (for example, due to an accidental drop) is applied to the portable electronic device. The hindering of relative movement helps to protect the portable electronic device from damage.
