Patent ID: 7520027

Claim:
A hinge comprising: a shank having an irregular shape, the shank including a threaded portion, a crown formed thereon and a head integrally formed with the threaded portion, wherein the crown is extending axially from the shank; a rotation bracket adapted to securely connect to a display of a laptop computer and having a hole being mounted around the head to keep the rotation bracket from rotating relative to the shank; a fixed bracket adapted to securely connect to a base of the laptop computer and having a through hole being mounted around the threaded portion of the shank to freely extend; a first friction bracket and a second friction bracket pivotally mounted around the shank and located at both sides of the fixed bracket respectively, the first friction bracket having a rod extending from a peripheral edge thereof to correspond to and extend through a securing hole defined in the fixed bracket, the second friction bracket having two arms extending from a peripheral edge thereof to be adjacent to each other, such that after the rod extends through the securing hole of the fixed bracket, the rod is clamped by the two arms of the second friction bracket to cause simultaneous pivotal movement of both the first and second friction bracket and the fixed bracket; multiple friction pads provided on opposite sides of the first friction bracket and the second friction bracket, wherein each of the friction pads has an aperture configured to fit the irregular shape of the shank for being mounted around the threaded portion of the shank so that the friction pads pivot together with the shank; a resilient assembly mounted on the threaded portion to provide urging force to the friction pads to abut the first and second friction bracket and the fixed bracket; and a securing member threadingly connected to the threaded portion to secure the friction pads, the first and second friction bracket and the resilient assembly on the shank.
