    with a lock case and a lock case guided in the lock case and movable between a closed position and an open position, with a lock nut rotatably mounted in the lock case for connection to a door handle and with a
    Closing force device, the lock nut interacting non-positively with the lock latch via a latch arm such that the lock latch can be moved from the closed position to the opening position as a result of rotation of the lock nut against the action of a restoring device, and the closing force device moves the lock latch from the open position to the Closes position.
    Locking arrangements of the type mentioned are provided for actuation with a handle which is connected to the lock nut by means of a square and non-positively. The non-positive connection to the lock latch acts on the lock latch as well as on the handle coupled to the lock latch by the lock nut. To carry out the closing movement of the lock latch, the lock nut is used by the
    Resetting device acting locking force pushed against a stop defining the closed position of the lock latch in the lock case. The striking is with a corresponding
    Noise development connected, which contradicts increased comfort requirements.

    To suppress the default with the
    With the known mortise lock lock noise, it is necessary to consciously guide the handle during the closing process until it reaches the closed position, in order to enable the stop noise to be suppressed by deliberately delaying the rotary movement of the handle in the final phase of the closing movement.
    The present invention is based on the object of proposing a locking arrangement which enables the stop noise to be automatically suppressed.
    This object is achieved by a locking arrangement with the features of claim 1.
    The locking arrangement according to the invention has a damper device which interacts with the lock nut, in such a way that the damper device during one of the final phases
    Reset device caused reset movement of the
    The lock nut is non-positively connected to the lock nut via a coupling device.
    The damper device according to the invention arranged in the lock case enables automatic damping of the restoring movement without external influence during the handling of the door handle connected with a mortise lock, so that due to the associated delay of the restoring movement before

    Stop against the stop formed in the lock case an impact noise is effectively suppressed.
    It proves to be particularly advantageous if the lock nut has a damping arm to form the coupling device, so that the design or arrangement of a coupling device in the lock case does not require the arrangement of a further component in the lock case.
    According to a preferred embodiment, a
    Actuating element of the damper device arranged in a contact distance to the coupling device, such that a body contact between the
    Damper device and the coupling device only during the final phase of
    There is a return movement. In this way it can be ensured that the damper device only becomes effective when the lock latch on the one hand has not yet reached the closing stop in the lock case, but on the other hand the closing movement against a closing position limited by the closing stop is carried out to the extent that it is flawless
    Ensure locking function.
    Alternatively, it is also possible to dampen the
    Closing movement during the final phase of the
    To achieve closing movement by the
    Damper device has an actuating element which is constantly non-positively connected to the coupling device, the damper device being designed such that a damping effect occurs exclusively during

    The lock nut preferably has a further arm for the non-positive connection to the reset device, so that the lock nut enables the restoring force caused by the reset device to be transmitted to the lock latch by the additional arm in addition to the actuation of the damper device by means of the damping arm.
    It is particularly advantageous if the
    Reset device is designed as a spring device, in a particularly preferred case, the spring device is designed as a torsion spring, such that one spring leg is attached to a support stop formed in the lock case and another spring leg is attached to the further extension of the lock nut designed as a spring arm currently
    If the damper device is designed as a linear damper with a damping fluid arranged in the lock case

    A displacer designed actuator, such that a damping effect is generated by a linear movement of the actuating element, can be a particularly simple embodiment of the
    Damper device can be selected to achieve the desired effect.

    In the final phase shown in FIG
    Closing movement, a body contact is formed between the damping arm 34 and the actuating element 33 in such a way that if the return movement of the lock nut 21 continues into the closed position shown in FIG. 1, a force-locking connection between the damper device 31 and the lock nut 21 via the damping arm 34 the lock nut 21 is formed and the further restoring movement is delayed by the damper device 31 during the final phase. As a result, a closing stop is formed between the latch arm 28 of the lock nut 21 and the stop pin 16 at a correspondingly reduced speed, so that the running strength of a stop noise is reduced.

In addition, a locking force device 48, which is designed independently of the restoring device designed as a torsion spring 25, is provided in the locking arrangement shown. The closing force device 48 has a magnetic device arranged opposite the lock latch 15 in a door frame. The magnetic device causes the lock latch 15 to be transferred from the opening position shown in FIG. 5 to the closed position shown in FIG. 4 at the moment when the door is pivoted flush into the door frame.
