ABSTRACT:
A seam-assembled continuous hinge for use on a door elbow which allows a door to be opened up to 180.degree. without forming a space in the longitudinal direction and permits disposing plates in any optional directions on a bed for mounting a box-like outer frame to which the continuous hinge is to be attached. This continuous hinge is configured to allow a door to be opened up to 180.degree. by coinciding an inner arc shape of a female type variable-diameter cylindrical portion 3 of a female type base plate 2 which is to be attached to a box-like outer frame 1 in which the universal fin plate 7 can be fitted and removed in optional directions with an outer arc shape of a male type variable-diameter cylindrical portion 4 of an integral door body 5 which is to be seam-assembled with the female type base plate and configuring the arc shape so as to be composed of a semicircle a located at a tip on a side of a center, and two arcs b and c which have progressively prolonged radii and centers located at different points, and are successive or adjacent to the semicircle a.
