(57) An adjustable door hinge (1) comprises a first body and a second body (2, 3) equipped
with respective securing flaps (4, 5), a hinge pin (6) which has a central axis (A6)
and which can be partly inserted into respective holes (9, 10) made in the hinge bodies
(2, 3), a respective centring bush (7) with an approximately cylindrical shape interposed
between the pin (6) and the hole (9), the bush (7) presenting a first radial protrusion
(11) extending longitudinally parallel with the central axis (A6), an adjustment element
(18) for varying the position of the hinge pin (6) inside the hole (9) and actuated
from the outside of the hole (9) in such a way as to operate between the pin (6) and
the hole (9) itself in such a way as to allow the pin (6) to perform a pendular movement;
the bush (7) also presenting a second radial protrusion (12) located diametrically
opposite the first protrusion (11), and designed to also engage with the first recess
(13) instead of the first protrusion (11), the protrusion (11, 12) that is not engaged
with the first recess (13) being positioned inside a second recess (14) also made
in an inside face (9a) of the hole (9) and extending radially in such a way as to
allow the protrusion (11, 12) itself to move during the pendular movement.
