A concealed door hinge for installation between a door edge and a door frame has two leaf assemblies that can be recessed in the door frame and in the door edge. Each assembly has a pair of longitudinally spaced housing ends each formed with a throughgoing screw-mounting hole for securing the housing end to the edge or frame and a hollow middle part extending longitudinally between and fixed to the housing ends. A swivel mechanism has at least two parts that interconnect the leaf assemblies. |
