Abstract:
A hinge device comprising:a male hinge member including a first mounting plate adapted to fix the male hinge member onto a display unit of a portable computer, and a pivoting rod extending opposite the first mounting plate and defining a first contacting section on an outer periphery thereof; a female hinge member including a second mounting plate adapted to fix the female hinge member onto a mainframe unit of a portable computer and a cylindrical body defining a connecting opening for holding the pivoting rod of the male hinge member therein and a second contacting section in an inner periphery thereof for contacting the first contacting section of the male hinge member, a receiving slot being defined in the second mounting plate for spacing the second contacting section from the second mounting plate, thereby maintaining the same torque resistance between the first contacting section and the second contacting section during rotation movements in different directions; and means for providing a smooth rotation operation between the male and the female hinge members.
