Abstract:
1. A hinge module for a three-step open type portable terminal including: an upper body; an intermediate body coupled to the upper body wherein the upper body is movable in a transverse direction or a longitudinal direction; a lower body coupled to the intermediate body wherein the lower body is movable in the transverse direction or the longitudinal direction perpendicularly to a movement direction of the upper body, wherein the hinge module prevents the upper and lower bodies from simultaneously moving into an opened position relative to the intermediate body; an intermediate plate fixed to the intermediate body of the portable terminal and formed with a longitudinal guide hole; an upper plate fixed to the upper body of the portable terminal, coupled to the intermediate plate wherein the upper plate is movable in a transverse direction relative to the intermediate plate, and provided with a guide track extending in transverse and longitudinal directions; and a lower plate fixed to the lower body of the portable terminal, coupled to the intermediate plate wherein the lower plate is movable in a longitudinal direction relative to the intermediate plate, and provided with a guide pin, which passes through the guide hole of the intermediate plate and moves along the guide track of the upper plate in order to prevent the upper and lower bodies from simultaneously moving into the opened position relative to the intermediate body.
