  • Two-axis hinge and mobile device
    Patent number: 8605418
    Abstract: A two-axis hinge unit is provided with a first rotating shaft that rotates so as to open in the vertical direction from a folded state with a first casing and a second casing overlapping and a second rotating shaft that rotates so as to open in the horizontal direction from a folded state with the first casing and the second casing overlapping, and is provided with a restriction member positioned between the first rotating shaft and the second rotating shaft that, when one of the rotating shafts is in a predetermined rotational position, is pressed by this one rotating shaft and engages with the other rotating shaft, thereby restricting rotation of that other rotating shaft.
    Type: Grant
    Filed: September 12, 2012
    Date of Patent: December 10, 2013
    Assignee: NEC Corporation
