ABSTRACT:
A hinge joint comprises a hinge leaf, a closure element, a knuckle bearing, a hinge bolt defining a hinge joint axis and pivotally mounting the closure element via the knuckle bearing, a hinge bearing having a base securable adjacent to an edge of an opening, the hinge bearing having legs between which the knuckle bearing is positioned and which carries the hinge bolt, the knuckle bearing having at least one first protrusion extending axially outwardly and arranged concentrically relative to the hinge bolt, one of the legs having an axially inwardly extending protrusion which axially overlaps the first protrusion, the hinge leaf together with the closure element being arranged so that it can be removed from the hinge bearing only after removal of the hinge bolt and after opening the closure element through a predetermined pivot angle, the first protrusion being annular, the second protrusion being formed as an enclosing retainer of one of the legs and arranged radially outside of one of the first protrusions, the enclosing retainer at at least one side face of the leg being provided with an access passage for the first protrusion, and cam means provided on the hinge leaf, so that only in a pivoted position of the closure element is a minimum dimension of the cam means extending perpendicular to the hinge joint axis with the hinge bolt removed, so that the passage of the first protrusion through an associated one of the access passages is possible.
