Patent ID: 8434197

Claim:
A biaxial hinge device comprising: a frame-side mounting member to be mounted to a frame; a door-side mounting member to be mounted to a door; a connecting arm, one end portion of the connecting arm rotatably connected to the frame-side mounting member via a first shaft, the other end portion of the connecting arm rotatably connected to the door-side mounting member via a second shaft disposed parallel to the first shaft; and a rotation control mechanism, the rotation control mechanism allowing the connecting arm to be rotated about the second shaft when the rotation control mechanism prohibits the connecting arm from being rotated about the first shaft, the rotation control mechanism allowing the connecting arm to be rotated about the first shaft when the rotation control mechanism prohibits the connecting arm from being rotated about the second shaft; the door-side mounting member being rotated with respect to the frame-side mounting member between a closed position and an open position by the rotation of the connecting arm about the first shaft and the second shaft, wherein a position adjustment member is disposed in the door-side mounting member such that the position adjustment member is rotatable about a central shaft, the central shaft being one of the second shaft and a shaft disposed parallel to the second shaft; a rotational position adjustment mechanism is disposed between the door-side mounting member and the position adjustment member, the rotational position adjustment mechanism adjusting rotational position of the position adjustment member about the central shaft; and, the rotation control mechanism is disposed between the frame-side mounting member and the position adjustment member on one side and the connecting arm on the other side.
