A concealed pivot hinge includes a first part having an elongated hollow bush adapted to be sunk into the edge of a door, and a second part having a pin and a colinear threaded portion, to be inserted through a door plate with said pin projecting for rotation in said bush. Identical such hinges may be fitted top and bottom, or one hinge may be replaced by a pin through a door plate engaging bushes in the door and plate and rotatable in at least one bush. |
