US Patent 7124473 Hinge for a notebook computer

A hinge for a notebook includes an L-shaped seat with a barrel. A pintle has a shaft extending in the barrel of the seat. A first tube, a sleeve and a second tube are in turn mounted on the shaft. The first tube and second tube are securely received in the barrel and each has a stop formed at a respective end facing the sleeve. The sleeve has two arcuate segments respectively formed at two ends and corresponding to the stops of the tubes. Thus, the sleeve can be rotated along with the shaft about the first and second tubes until one arcuate segment of the sleeve abuts the corresponding stop. Whereby, a user can raise the display with a small force to separate the display from the body and a large force to completely raise and position the display.
