A dual connection member allowing a liquid crystal display unit and a keypad of a mobile phone to rotate and a hinge device thereof are provided. The dual connection member may be used in a mobile phone wherein the mobile phone includes a first housing, a second housing and a dual connection member for interconnecting the first housing and the second housing in such a manner that the second housing is rotatable about a first hinge axis toward or away from the first housing, wherein the first and second housings are connected to the dual connection member in such a manner as to be rotatable about third and second hinge axes, respectively, which extend perpendicular to the front and rear faces of the first and second housings, respectively, the third and second hinge axes being eccentrically positioned in relation to the centers of the first and second housings, respectively, and allowed to be slid as the first and second housings are rotated.

Mobile phone having dual connection member and hinge device thereof

A portable terminal with a hinge apparatus is provided. The portable terminal includes a hinge apparatus which pivotally couples a pair of housings together. The hinge apparatus provides a first hinge axis and a second hinge axis which are perpendicular to each other. The hinge apparatus includes a first hinge shaft coupled to the first housing along the first hinge axis, a second hinge shaft coupled to the second hinge housing along the second hinge axis and rotating about the first hinge axis and the second hinge axis, a stopper slot formed on an outer circumferential surface of the first hinge shaft along the first hinge axis, a stopper groove formed on the second hinge shaft along a circumference thereof and encompassing a part of the outer circumferential surface of the first hinge shaft, and a stopper rib formed within the stopper groove and selectively engaging with the stopper slot. Thus, when one of the housings is rotated about one of the hinge axes, the housing is restricted from rotating about the other hinge axis.
