Double hinge mechanism for door or window in building has hinge pins in two hinge halves connected by C-shaped link and each half has height adjustment mechanism

摘要

A single broad C-shaped link (6) has through-bores to accommodate the two hinge pins. The hinge bands (4,5), fastened to the fixed and moving frame parts (1,2) have eyes in the edges (12,13) to accommodate the hinge pins, positioned above and below the C-shaped link. One or both hinge pins may be spring-loaded. The hinge bands are clamped to the frames by pairs of lattice-structure curved levers (15,16), tensioned by nuts (20) on bolts (19).
