Hinge which is composed of two U-shaped metal profiles with complementary recessed and projecting zones to be assembled together to form a hollow passage for the inserted hinge pin

摘要

The hinge structure has two metal components (20,40) in a U-shaped profile. The components (20,40) are shaped with alternating projections (26,48) and corresponding recessed zones (28,46). The projections (26,48) are shaped to form a hollow passage. When the two components (20,40) are fitted together, their meshing projection and recessed zones form a passage for the insertion of the hinge pin (60).
