  • Publication number: 20070123319
    Abstract: A portable terminal includes: a first housing; a second housing rotatably connected to the first housing to open or close the housings. A hinge device interconnects the first and second housings. The hinge device provides first and second hinge axes extending perpendicular to each other, wherein the hinge device limits the rotation of the second housing about the second hinge axis when the second housing has been rotated about the hinge axis to the open position, and the hinge device limits the rotation of the second housing about the first hinge axis when the second housing has been rotated to the open position. The portable terminal with the inventive dual axis hinge device is configured in such a way that one housing can be positioned at the top side or lateral side of the other housing, whereby it is convenient to use the portable terminal and it is possible to secure structural stability and reliability.

  • Publication number: 20060042044
    Abstract: A biaxial hinge device and a mounting mechanism thereof for a mobile terminal is provided. The biaxial hinge device includes a first hinge module for rotatably connecting the folder to the body around a first hinge axis, and a second hinge module for rotatably connecting the folder to the body around a second hinge axis, which is spaced apart form the first hinge axis and disposed in a direction substantially perpendicular to the first hinge axis. A portion of a second hinge module is inserted in the first hinge module, thereby allowing the second hinge module to move both independently of and in cooperation with the first hinge module.
