ABSTRACT:
An improved latch hook mechanism for portable PCs and the like is disclosed. In a preferred embodiment, a portable PC latch mechanism of the present invention comprises a latch assembly including a latch hook disposed on the exterior of the bezel portion of the lid of the PC and connected to an arm of approximately the same length as the latch hook via a longitudinally disposed spring member, both of which are disposed within the interior of the lid. The spring member defines an axis about which the latch hook and the arm may be caused to rotate relative to one another when force is applied to the free end of the arm. One end of a ribbon cable is connected to the free end of the arm. The remainder of the cable is arranged such that it extends down the interior of the lid of the PC through one of the hinges connecting the lid to the base of the PC and is secured to the rear interior of the base via a hook or screw. The cable is of a length sufficient so as not to exert force on the arm when the lid is in an open position such that when the lid is in an open position, the latch hook rests in a recess provided in the bezel of the lid such that the latch hook lies flush with the surface of the lid. The cable is further of a length such that as the lid is rotated to a closed position, increasing force is applied by the cable to the arm of the latch assembly such that the latch hook is caused to rotate out of the recess for engagement with a receptacle in the base.
