In another embodiment, a door (4) includes such a hinge closure (1). ## Claims ### Claim 1 A hinge closure comprising: a first hinge element for arrangement on a door; a second hinge element for arrangement on a door frame; a locking device for interlocking the first hinge element and the second hinge element; an actuating device for actuating the locking device; and an emergency unlocking device for unlocking the two hinge elements. ### Claim 2 (depends on 1) The hinge closure as claimed in claim 1, wherein the emergency unlocking device and the actuating device are arranged on opposite sides of the hinge closure. ### Claim 3 (depends on 1) The hinge closure as claimed in claim 1, wherein the emergency unlocking device is couplable with the locking device and/or with the actuating device. ### Claim 4 (depends on 1) The hinge closure as claimed in claim 1, further comprising a blocking device having closing cylinder and a blocking element that blocks the actuating device and/or the locking device. ### Claim 5 (depends on 4) The hinge closure as claimed in claim 4, wherein the closing cylinder is arranged on the actuating device and is movable between a blocking position and an unblocking position, and wherein the closing cylinder interacts with the blocking element in the blocking position in such a manner that the actuating device is fixed in relation to the blocking element. ### Claim 6 (depends on 4) The hinge closure as claimed in claim 4, wherein the blocking element and/or the closing cylinder permit the actuating device to be transferred to a locking position when the closing cylinder is in the blocking position. ### Claim 7 (depends on 1) The hinge closure as claimed in claim 1, wherein the emergency unlocking device includes an emergency actuation region for emergency unlocking via the locking device and/or the actuating device. ### Claim 8 (depends on 7) The hinge closure as claimed in claim 7, wherein the emergency actuation region comprises a first effective contour for unblocking the blocking device and a second effective contour for emergency unlocking of the locking device and/or of the actuating device. ### Claim 9 (depends on 8) The hinge closure as claimed in claim 8, wherein the effective contours are arranged so that for emergency unlocking, first the blocking device is unblocked via the first effective contour and then, for unlocking the hinge elements, the second effective contour unlocks the locking device and/or the actuating device. ### Claim 10 (depends on 8) The hinge closure as claimed in claim 8, wherein the locking device comprises a coupling contour, which is designed corresponding to the second effective contour of the emergency unlocking device, wherein in the case of emergency unlocking, the effective contour interacts with the effective contour. ### Claim 11 (depends on 8) The hinge closure as claimed in claim 8, wherein the first effective contour is a notch and the second effective contour is a run-on slope. ### Claim 12 (depends on 1) The hinge closure as claimed in claim 1, wherein the emergency unlocking device is in the form of a drive-in bolt. ### Claim 13 (depends on 1) The hinge closure as claimed in claim 1, wherein the emergency unlocking device is secured against movement in a direction opposite to an emergency unlocking direction in a basic position. ### Claim 14 (depends on 1) The hinge closure as claimed in claim 1, wherein the emergency unlocking device is guided in a guide element and is sealed via a sealing element in relation to the guide element. ### Claim 15 (depends on 1) A door having at least one of the hinge closures as claimed in claim 1. ### Claim 16 (depends on 15) The door as claimed in claim 15, wherein two of the hinge closures are arranged on each of two opposite end regions of the door.
