<p><P>PROBLEM TO BE SOLVED: To provide a secret hinge having a configuration taking out a door while largely avoiding a vertical-frame this-side corner, capable of rotating and operating the door, and capable of being adapted to wide-width accommodation. <P>SOLUTION: A blade having a first axial center and a second axial center at both ends, a rotary cam having projecting sections at both ends, a vertical-frame side case fitting a frame-side guide member with a frame-side deformed groove and a first axial-center inserting hole and a door-side case fitting a door-side guide member with a door-side deformed groove and a second axial-center inserting hole are mounted. The door-side case and the vertical-frame side case are connected by the blade in a state that one projecting section of the rotary cam is engaged with the frame-side deformed groove and the other projecting section is engaged with the door-side deformed groove. The position of the blade is defined at all times to each angular position of the door by an operation slowly moving the projecting sections of the rotary cam in both the deformed grooves, and a peculiar open-close locus opened while simultaneously controlling the door and the blade is obtained. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
