(57) A hinge for door and window frames, in particular for metal door and window frames,
comprises two half-bodies (2, 3) which can be connected, using means (4), to a fixed
frame (5) and to a mobile frame (6), respectively, each frame consisting of a section
(P); these half-bodies (2, 3) are attached to one another by a hinge pin (7) and each
consists of a single element, made using plastic deformation, with a substantially
flat first, central portion (8), extending on one side without interruptions, in a
second portion (9) deformed in such a way that it closes over itself like a cylinder
in order to house the hinge pin (7), and, on the other side, in a third portion (10),
angled relative to the first portion (8), and having a section (P1) designed to allow
the third portion to be connected to a seat (11) in the section (P) which constitutes
the frame; the third portion (10) also having means (4) for connection to the frame
(5, 6).
