Patent attributes
A hinge assembly adapted for a housing having a main body and a sub-body rotatably positioned on the main body, the hinge assembly including: a first hinge portion adapted to rotatably support both lower sides of the sub-body; and a second hinge portion adapted to rotatably support a rear surface of the sub-body with a surface contact and to maintain a rotated angle of the sub-body. The first hinge portion includes: a hinge protrusion arranged on one side surface of the sub-body; a hinge protrusion inserting-hole arranged on one side surface of a sub-body rotational space and adapted to receive the hinge protrusion; a hinge-hole arranged on the other side surface of the sub-body; a through-hole arranged on the other side surface of a sub-body rotational space to correspond to the hinge-hole; and a hinge locker passing through the through-hole and the hinge-hole. The second hinge portion includes: a curved portion protruding from a bottom surface of the sub-body and having a gear groove arranged on the surface thereof; a window arranged on the sub-body rotational space of the main body and passing through the curved portion; and a pinion rotatably positioned at a predetermined position, the pinion arranged to be rotated together with the sub-body upon the sub-body being rotated in engagement with the gear groove.
