Abstract

A hidden hinge system for furniture and doors has recessed mountings in the fixed frame and movable frame and linked by two interlocking hinge brackets to operate as a lift off hinge. One hinge bracket has a forked shape while the second hinge bracket has a central flange which fits into the forked shape enabling the hinge to occupy a compact space. The separate mountings have alignment adjustments to hang the door.

3. The hinge according to claim 2, further comprising a set screw inserted in a threaded hole of said first mounting base and wherein a first eccentric element of said eccentric elements is a horizontal adjustment element arranged for rotational movement on said set screw, said first eccentric element engaging into an eccentric receptacle mount of an associated connector and being secured at the associated connector in any desired adjustment position by the set screw.

4. The hinge according to claim 2, wherein upper and lower connectors are arranged in said first mounting base, said upper and lower connectors have respective first and second eccentric adjustment elements for horizontal adjustment, and wherein said hinge further comprises a third eccentric adjustment element rotationally mounted in said first mounting base and supporting said lower connector for vertical adjustments of said lower connector.

5. A hinge for hidden installation between a door post and a door, both having recesses formed therein, comprising

(a) first and second mounting bases for insertion in recesses in the door post and in the door, said second mounting base having a guiding recess and adjustment screws retained on a rear face of said second mounting base in a rotationally movable manner and capable of horizontal displacement;

(b) at least two connectors disposed on surfaces of said mounting bases, the connectors arranged in said second mounting base being arranged in said guiding recess so as to be horizontally mounted and containing threaded holes into which said adjustment screws are inserted;

(c) a first hinge bracket comprising first and second fork arms defining an open space and an integrally-formed adjourning rearward connecting section connecting said fork arms, said connecting section and said fork arms being mounted on said connectors; and

(d) a second hinge bracket comprising a middle element and integrally-formed first and second end segments connected to and projecting upwards and downwards respectively from each end of said middle element, said middle element being inserted in said open space and being rotatably mounted on said fork arms, said first and second hinge brackets cooperating with and pivotally connected to each other for movement about a first vertical axis of rotation, said first hinge bracket having an end segment mounted on the first mounting base so as to pivot about a second vertical axis of rotation and having another end segment guided for longitudinal movement on the second mounting base, said first end segment of said second hinge bracket being mounted on the second mounting base so as to pivot about a second vertical axis of rotation and said second end segment of said second hinge bracket being guided for longitudinal movement on the first mounting base, said connectors having upper and lower parts, supporting said end segments, and said hinge brackets extending vertically over a same level of height.

6. The hinge according to claim 5, wherein each of said adjustment screws has a journal-shaped extension and the rear face of said second mounting base contains longitudinal holes through which a respective one of said journal-shaped extensions passes.

7. The hinge according to claim 5, further comprising an eccentric adjustment element arranged in said second mounting base for horizontal adjustment of the connectors associated with said second mounting base.

8. A hinge for hidden installation between a door post and a door, both having recesses formed therein, comprising
