Abstract:
1. A hinge plate for concealed placement between a door frame and a door panel comprising: (a) first and second mounting bases for insertion into recesses in the door frame and in the door panel; (b) first and second cooperating hinge brackets connected to rotate about a first vertical axis of rotation; and (c) a longitudinal guide provided on each of said first and second mounting bases; wherein on each of said first and second mounting bases, an end of said first hinge bracket is mounted to rotate about a second vertical axis of rotation and an end of said second hinge bracket is guided to move longitudinally in said longitudinal guide, said first and second hinge brackets forming identical in a view parallel to the vertical axes U-shaped connection elements, each connection element consisting of two vertically oriented shanks and a single connection stay between said shanks; wherein the hinge brackets have an articulated connection comprising a bushing and a pin insertable into the bushing, and each connection stay contains a dead-end bore for receipt of the bushing or the pin, so that said first and second hinge brackets plug into each other for rotation at the connection stays; and wherein the vertically oriented shanks bridge the distance between the mounting bases and reach directly up to the mounting bases both on the top and on the bottom; axles mounted on the mounting bases, said axles having a two-axis offset relative to one another when the hinge plate opens, in all functional positions of the hinge plate; adjustable inserts disposed in the mounting bases, the ends of the hinge brackets being mounted on said inserts and guided to move longitudinally; and wherein the inserts of the first mounting base are disposed in a guide recess of said first mounting base, so as to be horizontally or vertically adjustable, and the inserts of the second mounting base are disposed to be adjustable orthogonal to a front side of said second mounting base.
