(57) A hinge for doorframes, adjustable on three axes, envisages first adjustment means
(11) for a hinge pin (6), on a hinge body (2), comprising means (35) for the integral
connection of a bushing (7) and the relative portion of the pin (6) housed inside
it, so as to define a single adjustable body. Moreover, the bushing (7) has an outer
radial projection (12) which can be engaged in a corresponding notch (13) in the inner
surface of a hole (9) in the hinge body (2), the projection (12) - notch (13) connection
being designed to define a pivoting point (F), in the style of a cam, for the bushing,
allowing the bushing and the portion of the pin (6) housed in it to be made to perform
a pendular movement in both directions, by relative means (14) which can be operated
from the outside and which act between the pin (6) and the hole (9), allowing adjustment
of the position of the pin (6). Second adjustment means (111) are also envisaged,
for adjustment on the vertical axis (Z), the means located and acting on the other
hinge body (3), so as to obtain a variation in the relative axial distance (H) between
the first and second hinge bodies (2, 3).
