US Patent 7088588 Coupling structure

A coupling structure includes a hook bar and a force receiving member adopted for use on an electronic device that has a folding member such as a notebook computer that consists of an upper lid and a base. The folding member is the upper lid. The force receiving member and the hook bar have respectively a portion exposed from two neighboring sides of the upper lid, and are coupled by a turning mechanism. When the force receiving member is depressed, it is moved longitudinally towards the upper lid. The turning mechanism transfers the force to push the hook bar moving transversely so that the latch tenons on the hook bar may escape the latch holes on the base to control the coupling condition.
