The hinge (10) has a swiveling axle (32) that is connected with hinge units (12, 14) in an operating condition of the hinge, such that a hinge side piece (22) of the hinge unit (14) is swivelable in a swiveling direction around the swiveling axle for releasing a door opening limited by a door frame. The swiveling axle is decoupled from the hinge units in another operating condition of the hinge. Another swiveling axle is connected with the hinge units, such that two hinge units are swivelable around the latter swiveling axle in another swiveling direction for releasing the opening.
