Apparatus for actuating the lock of an automatic central-buffer coupling of a track-guided vehicle, in particular rail vehicle, wherein the apparatus has the following: - an actuating arm which is articulated on a housing of the central-buffer coupling so as to be pivotable about a first axis of rotation; - an actuating shaft which is mounted so as to be rotatable about a second axis of rotation, extending parallel to the first axis of rotation, relative to the housing of the central-buffer coupling and which is operatively connected or operatively connectable to the lock of the central-buffer coupling; and - a lever mechanism for transmitting a torque which is generated upon actuation of the actuating arm to the actuating shaft; characterized in that the lever mechanism is configured to realize a latching position of the actuating arm, wherein the latching position corresponds to a locking position of the lock, and wherein, in the latching position, the actuating arm is in a beyond-dead-centre position, wherein the lever mechanism has a coupling arm which is preferably fixedly and in particular rotationally conjointly connected or connectable to the actuating shaft and the lever mechanism has at least one lever arm via which the actuating arm is operatively connected to the actuating shaft, wherein the at least one lever arm is articulated on the actuating arm in such a way that, upon actuation of the actuating arm, this is pivoted about a third axis of rotation, which is parallel to the first and second axes of rotation (3, 5), relative to the at least one lever arm and the at least one lever arm is articulated on the coupling arm in such a way that, upon actuation of the actuating arm, the at least one lever arm is pivoted about a fourth axis of rotation, which is parallel to the first and second axes of rotation (3, 5), relative to the coupling arm, wherein the at least one lever arm has a rectilinear region articulated on the coupling arm so as to be pivotable about the fourth axis of rotation relative to the coupling arm and has a curved region articulated on the actuating arm so as to be pivotable about the third axis of rotation relative to the actuating arm. - an actuating arm which is articulated on a housing of the central-buffer coupling so as to be pivotable about a first axis of rotation; - an actuating shaft which is mounted so as to be rotatable about a second axis of rotation, extending parallel to the first axis of rotation, relative to the housing of the central-buffer coupling and which is operatively connected or operatively connectable to the lock of the central-buffer coupling; and - a lever mechanism for transmitting a torque which is generated upon actuation of the actuating arm to the actuating shaft; characterized in that the lever mechanism is configured to realize a latching position of the actuating arm, wherein the latching position corresponds to a locking position of the lock, and wherein, in the latching position, the actuating arm is in a beyond-dead-centre position, wherein the lever mechanism has a coupling arm which is preferably fixedly and in particular rotationally conjointly connected or connectable to the actuating shaft and the lever mechanism has at least one lever arm via which the actuating arm is operatively connected to the actuating shaft, wherein the at least one lever arm is articulated on the actuating arm in such a way that, upon actuation of the actuating arm, this is pivoted about a third axis of rotation, which is parallel to the first and second axes of rotation (3, 5), relative to the at least one lever arm and the at least one lever arm is articulated on the coupling arm in such a way that, upon actuation of the actuating arm, the at least one lever arm is pivoted about a fourth axis of rotation, which is parallel to the first and second axes of rotation (3, 5), relative to the coupling arm, wherein the at least one lever arm has a rectilinear region articulated on the coupling arm so as to be pivotable about the fourth axis of rotation relative to the coupling arm and has a curved region articulated on the actuating arm so as to be pivotable about the third axis of rotation relative to the actuating arm.
