<p>The hinge which can be adjusted in three perpendicular directions comprises a threaded body (46) which extends along a vertical axis (X,X') and has a spherical upper end (45). The body passes through an oblong hole (47) in a first hinge element (48) and is secured in position by two locking nuts (50,51) which bear onto opposite sides of the hole. The spherical end of the body supports a cap (52) from which a threaded rod (53) extends vertically upwards also along the axis (X,X'). The rod passes through an oblong hole (47) in a second hinge element (54) and is secured in position by a nut (55).</p> |
