1. A portable information handling system comprising:
- a main housing portion having a keyboard for accepting key inputs;
a lid housing portion having a display for presenting information as visual images;
a processor operable to execute instructions to process information;
a memory interfaced with the processor, the memory operable to store the information;
a display disposed in the lid housing portion and interfaced with the processor and memory, the display operable to present the information as visual images; and
a hinge coupled to the main housing portion and lid housing portion to hold the main and lid housing portions in rotational relationship with each other, the hinge having a first support element coupled to the main housing portion and a second support element coupled to the lid portion, each support element having a pinion gear, the hinge having a rack disposed between and engaged with each pinion gear, the hinge transferring force between the main and lid housing portions by interaction of the rack and the pinion gears and;
a flexible cover enclosing the hinge, the rack pressing against the flexible cover to expand the flexible cover during rotational motion of the main and lid portions.

Abstract
A portable information handling system has lid and main portions rotationally coupled to each other with a set of hinges having motion managed by rack and pinion gears. The rack translates motion between pinions by moving outward from the housing portions during rotation of the housing portions. A flexible cover over the rack stretches in response to movement of the rack to contain the hinges within the portable information handling system structure.

8. A method for rotationally coupling a portable information handling system first and second housing portions, the method comprising:
-
rotating the first portion relative to the second portion; translating the rotating from a pinion of the first portion to a rack and from the rack to a pinion of the second portion; and moving the rack between the pinions, the rack extending outward from the pinions as the first and second housing portions move to a position proximate to each other and; enclosing the rack and pinions in a flexible material; and stretching the flexible material with force translated by the rack extending outward. - View Dependent Claims (9, 10, 11, 12, 13)
