<p><P>PROBLEM TO BE SOLVED: To provide a quadric link type invisible hinge simple in structure with a large rotation angle. <P>SOLUTION: One main link 41 and two auxiliary links 46 are inserted between two chassis 11, 21, and connection holes of the main and auxiliary links corresponding to one chassis, and connection holes of the main and auxiliary links corresponding to the other chassis are connected to form joints. As to the position relationship of the joints, in one chassis, the joint 53 for the main link is arranged on one bottom side of the chassis width, and the joint 55 for the auxiliary link is arranged on the flange side of the chassis and inside the chassis rather than the joint 53 for the main link, and in the other chassis, the joint 54 for the main link is arranged on the flange side, and the joint 56 for the auxiliary link is arranged vertically on the bottom side on the same side as the one chassis so that loci of a line segment which connects the joints 53, 54 on the main link side and a line segment which connects the joints 55, 56 on the auxiliary link side intersect after rotation from a non-intersecting state before rotation when shifting two chassis to be parallel from the facing state. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
