Abstract
An information handling system hinge provides friction against rotational motion to generate torque that regulates housing portion relative position. Friction is generated by compression of friction elements with a super elastic wire under tension. For example, a nickel titanium alloy wire under two to eight percent strain provides a relatively low spring rate having consistent compression even as wear reduces the size of the friction elements.
Claims9
-9. (canceled)
A method for rotationally coupling information handling system housing portions, the method comprising:
- disposing friction elements between first and second hinge brackets;
- compressing the friction elements with a super elastic wire placed under tension;
- and
- resisting with the friction elements rotation of the first and second hinge brackets.
