ABSTRACT:
An improved recessing hinge mechanism for doors and the like is comprised of an anchor member slidably supporting an upper end of an arm of a selectively expandable stabilizer device having two cooperative arms pivotably joined to one another at their respective midpoints and pivotably supporting a lower end of the opposite arm, with the ends of the respective arms, opposite those attached to the anchor member, being slidably/pivotably attached to a support/pivot rod, which pivotably carries the pivot edges of a door. For a recessing operation, the door is pivoted about the rod from a closed position to an open position, parallel to the expanded stabilizer device and then linearly moved toward the anchor member, with the scissors-like stabilizer device closing to a minimum dimension so that the support rod stops adjacent to the anchor member. The inventive hinge mechanism provides a ratio of recess depth to door width which is greater than about 1:0.95.
