Abstract
Abstract A hinge device for connecting a main body and a display unit of a portable computer includes a projection, a hinge member, and attachment units. The projection extends from a lower edge of the display unit, and the hinge member extends outwardly from both sides of the projection and connects to respective attachment units. A groove for receiving an end portion of hinge member is formed in each attachment unit. Each groove has a shape that is complementary to the shape of the end portion of the hinge member, so that the end portion of the hinge member easily inserts into the groove. In a preferred embodiment, one attachment unit is fixedly installed on the main body of the computer, and the other attachment unit is detachably connected to the main body. The attachment units and projection define a pivot axis about which the display unit rotates relative to the main body.
