An essential aspect of the invention is the particularly advantageous and compact arrangement of a motor-driven and, if necessary, remotely controllable door opener and a door closer in a door operating device on the same side of the door, preferably on the inside of a building exterior door. Escape doors in exterior walls of buildings, in particular, open and generally swing outward. It is therefore particularly advantageous to place both the door opener and the door closer relative to the pivoting side of the door, that is, on the inside of the building, since they are there against unwanted external influences, e.g. by weather or persons, are better protected.

Compared to door operators, which guide the door leaf in both the opening and closing direction by a motor, the present disclosure has a constructive advantage by the separation of the functions for opening and closing the door. When actively closing a door by a motor, in particular by a too high closing force, in principle, the risk of injuring people or damage objects. Such door drives are therefore subject to special machine guidelines and safety regulations. Such requirements can lead to an increase in the manufacturing costs of the door operating systems. The present disclosure includes a passive door closer with an energy storage that is charged upon opening the door and returns the power to close in a structurally limited extent. The disclosed door actuator is therefore structurally much simpler and thus economically cheaper to produce than a door drive as described above.

The swivel side ( 54 ) in the sense of this disclosure refers to the side of a door ( 5 ), in which the door leaf ( 52 ) opens. 3 shows an embodiment of the door operating device with the door open. The door closer ( 30 ) is directly on the door frame ( 51 ) and preferably comprises a locking mechanism ( 31 ) with a mechanical spring inside the door closer ( 30 ). The locking mechanism ( 31 ) also includes a locking lever ( 310 ), which is adapted to a moment or a force between the door leaf ( 52 ) and the door closer ( 30 ) or the door frame ( 51 ) to which it is mounted. In the embodiment shown, the end point of the closing lever slides ( 310 ) in a functional rail ( 40 ) along the door panel ( 52 ) and converts the torque about the axis of rotation of the locking mechanism ( 31 ) in a force on the door leaf ( 52 ) around. The locking mechanism is both in the opening direction ( 53 ) as well as in the opposite direction with the door leaf ( 52 ) or the functional rail ( 40 ) kinematically coupled. In an alternative embodiment, the closing mechanism ( 31 ) several closing levers ( 310 ), one of which is firmly attached to the door leaf.

The door opener ( 20 ) comprises an opening mechanism ( 21 ), which is driven by a motor and possibly remotely controllable, and the door closer ( 30 ) a separate locking mechanism ( 31 ), which in turn has an energy storage that is charged when the door is opened and provides energy to close the door. This aspect distinguishes the disclosed door operator substantially from door operators which operate in both the opening and closing directions with a motor.

The door actuating device comprises in an advantageous embodiment, a holding device ( 33 ) for the door leaf ( 52 ), which serves to keep the door in the open position. The holding device ( 33 ) can preferably by a mechanical catch in the door closer ( 30 ) be formed. Alternatively, the holding device ( 33 ) in the motor drive ( 23 ) form electrically or mechanically, eg with a switchable freewheel. Preferably, the Holding device ( 33 ) switchable and / or remotely controllable trained.

The door operator preferably comprises a retaining bracket ( 10 ) for fastening and special arrangement of the door opener ( 20 ) on the door frame. Due to the arrangement of the door opener ( 20 ) below the door closer ( 30 ) the opening lever ( 210 ) and the closing lever ( 310 ) not in their movement when opening the door. It is particularly advantageous if the retaining bracket ( 10 ) is shaped such that it is between the housing of the door closer ( 30 ) and the closing lever ( 310 ) can be arranged.

The door operating device may additionally include a functional rail ( 40 ). This can attack surfaces for the forces of the opening mechanism ( 21 ) and the locking mechanism ( 31 ) provide. Preferably, the functional rail ( 40 ) as a guide rail of the locking mechanism ( 31 ) educated. The locking mechanism may comprise a sliding block, which in the functional rail ( 40 ) and so a translational movement of a point of the locking mechanism along the door leaf ( 52 ). A common functional rail ( 40 ) for door opener and door closer is particularly advantageous for a compact design and a favorable wear behavior. The functional rail ( 40 ) can on a door leaf ( 52 ) and both the forces of the door opener ( 20 ), in particular via an external rolling contact ( 212 ), as well as the forces of the door closer ( 30 ) take up. To produce a particularly favorable kinematics, the end of a closing lever ( 30 ) in the functional rail ( 40 ) on the door leaf ( 52 ) slide along.

The door opener ( 20 ) and the door closer ( 30 ) of the door operating device are formed in a preferred embodiment, in a plane on the door leaf ( 52 ), in particular via a shared functional rail ( 40 ), to act. The opening mechanism ( 20 ) and the locking mechanism ( 30 ) act separately on the door leaf ( 52 ), in particular since the closing mechanism both in the opening and closing direction with the door leaf ( 52 ) is kinematically determined, whereas the opening mechanism ( 21 ) only in the opening direction ( 53 ) can transmit a force to the door leaf and is free in the closing direction.

An alternative embodiment of the door operator is achieved by kinematic reversal. In order to transmit the required moments or forces between the door frame and door leaf, the door opener and / or the door closer can also be attached to the door leaf. In this case, the opening or closing mechanism acts on the door frame or a holding bracket. The retaining bracket acts in this case as a power input of a door operating device. As an alternative to the preferred embodiment, the holding section may be designed to provide an active surface for an opening mechanism. The retaining bracket is in any case designed to receive the forces of the door opener for opening the door, in particular against a closing force of the door closer, and to transmit it to the door frame or the door leaf. For this purpose, the retaining bracket is formed by their shape particularly favorable.

Another embodiment comprises only one door operating mechanism. The separation of the opening and closing function is ensured in this case by a freewheel in or on the motor drive. The motor drive ( 23 ) and the energy storage ( 32 ) can also be accommodated in the same structural unit.
