Cabinet hinge

For use in a cabinet having a box-like carcass with carcass walls, and having an open side narrowed by a frame formed by strip-like frame members projecting each at right angles from one of the carcass walls toward an opposite carcass wall, at least one recess in one of the frame members, said carcass being open from front to back of the frame member and cut from the free front face of the frame member in the direction of the adjacent carcass wall:

• a hinge for pivotally mounting a door leaf to said cabinet, said hinge comprising:
• a door-leaf-related hinge part fastenable sunkenly in an opening in the back of the door leaf, a frame-related hinge part, and a link mechanism pivotingly coupling said hinge parts, said frame-related hinge part having a mounting piece to be fitted and mounted into the frame member recess, and a block joined by said link mechanism to said door-leaf-related hinge part and to be displaceably disposed in the recess parallel to the front side of the frame and at right angles to the end face of the frame member, slot and key joints provided between confronting lateral defining surfaces of said block and said mounting piece, whereby said block is guided for longitudinal displacement in the mounting piece, and a screw element joining said block to the mounting part, said element having a threaded shank in engagement with a counter-thread in said block and held in said mounting piece rotatably, but nondisplaceably in the longitudinal direction of said shank, said screw element being a threaded spindle disposed in a bore formed partially in said block and partially in said mounting piece and laid across the plane of separation between the lateral defining surface of the block and said confronting defining surface of said mounting piece, a circumferential groove interrupting the thread of the threaded shank of the spindle, and a projection protruding from a plain bore portion formed in said mounting piece and engaging said groove, and a bore portion in said block and provided with a counter-thread complementary to the thread of the threaded spindle.
