A hinge device comprises a male hinge member and a female hinge member. The male hinge member includes a pivoting rod at an end thereof, and a first mounting plate at an opposite end thereof, the first mounting plate being used for fixing the male hinge member onto a display unit of a portable computer. The female hinge member includes a body and a second mounting plate for fixing the female hinge member onto a mainframe unit of the portable computer. A first contacting section is defined on an outer periphery of the pivoting rod of the male hinge member. A second contacting section is defined on an inner periphery of the body for contacting with the first contacting section. A pair of grooves are defined in the second contacting section for retaining lubrication grease. The second mounting plate defines a receiving slot adjacent to the second contacting section for spacing the second contacting section from the second mounting plate to obtain a uniform torque resistance during rotation movements of the second contacting section in different directions.

Lubricated hinge device

A hinge device of the present invention comprises a male hinge member, a female hinge member and a resilient tube. The male hinge member includes a connecting shaft at one end, a mounting plate at an opposite end and a shoulder between the connecting shaft and the mounting plate. The connecting shaft of the male hinge device forms a receptacle therein for receiving the resilient tube. Four channels are longitudinally defined in the connecting shaft and equiangularly distributed in the shape of a cross to prevent loss of friction in the hinge device. An arcuate surface is formed at each edge of the channels. The female hinge member includes a sleeve and a mounting plate extending from one end of the sleeve, the sleeve having a receiving opening for receiving the connecting shaft of the male hinge member. A longitudinal slot is defined through the resilient tube for enhancing resiliency and allowing expansion of the resilient tube.
