In 1 is a building door that can be driven automatically on request 10 in the form of a swing door 12 with door drive 14 shown.

The building door 10 has one here as a rotary wing 16 trained wings 18 and a frame 20 ,

The rotary wing 16 is by means of door hinges or door hinges 22 around a lateral vertical axis 24 turning pivotally on the frame 20 hinged. The wing 18 is, as is well known in the case of room doors or other building doors, with a door handle 26 equipped for manual actuation of a door lock, not shown. By pressing the door handle 26 can be a (not shown) Türschnäpper from its closed position on a (not shown) strike plate of the frame 20 pull out so the wing 18 to open manually.

For optional automatic actuation is the door drive 14 provided, which is a door drive housing 28 and a motor-driven door drive arm 30 having. There are different types of mounting possible. For example, the door drive housing 28 on the wing 18 be mounted, with the free end of the door drive arm 30 stationary in the area of the frame 20 is connected. Shown is an example of a mounting method where the door drive housing 28 stationary in the area of the frame 20 is attached, and a free end of the door drive arm 30 on the wing 18 connected.

Also, different ways of connecting the Türantriebsarms 30 conceivable. In the example shown is a slide rail 32 provided on or in the one free end of the door drive arm 30 upon movement of the door drive arm 30 can slide. Another, not shown here drive is a so-called Knickarmgestänge, the door drive arm 30 forms a first rod member which is hingedly connected to a second rod member, which in turn is connected to its other end.

These aforementioned types of installation are in door drives 14 for swing doors 12 well known and will not be explained here.

The wing 18 abuts on (not shown) door seals, whereby the passage of draft through the building door 10 is avoided. In this final closing position is the wing 18 by the on the strike plate of the frame 20 held by attacking door flycatcher.

3 schematically shows the internal structure of an embodiment of the door drive 14 ,

The door drive 14 has an electric motor 34 on top of a door drive gearbox 36 to the door drive arm 30 is coupled by a gear, that a rotation of a motor shaft 38 of the electric motor 34 a movement of the door drive arm 30 generates and vice versa a movement of the door drive arm 30 a rotation of the motor shaft 38 of the electric motor 34 results.

To the motor shaft 38 is a position transmitter 40 connected.

The door drive gearbox 36 is form-fitting, ie substantially slip-free or provided with little residual slip, so that on the motor shaft 38 through the locator 40 a position of the door drive arm 30 connected wing 18 is detectable.

Next, the door drive 14 a door drive control 42 for controlling the operation of the door operator 14 on.

To the door drive control 42 is one through an antenna 44 symbolized radio receiver connected, which may be a bidirectional radio transceiver, and signals from one in 1 illustrated mobile remote control 46 , in particular radio remote control, can receive.

Next is the door drive control 42 a stationary signal generator 48 (or a stationary remote control) can be connected. The signal generator 48 can, as indicated, wired or also via a radio link with the door drive control 42 be connected. The signal generator 48 is for example by means of keys from a person to operate the door drive 14 actuated.

The door drive control 42 further has a user interface 50 For example, with keyboard or selectors or slide switches, by means of which a user makes adjustments to the door drive control 42 can make.

Next, the door drive 14 a lighting 52 which can also be used as an optical signal for a user.

The door drive control 42 is at the position transmitter 40 connected to positions of the connected door leaf 18 as well as position changes.

Next is the door drive control 42 to the electric motor 34 connected to the electric motor for automatically driving the grand piano 18 head for.

Next is the door drive control 42 adapted to the power requirement of the electric motor 34 capture. For example, this is the power consumption, the speed and / or the voltage or the current of the electric motor 34 recorded in order to obtain conclusions about the current force to be used.

For example, the door drive control may be operated in an automatic mode to the wing 18 to move motorically between its closing end position and an open position.

Such an automatic mode can be initiated, for example, by a pulse train operation. For this purpose, a person, for example, an automatic opening of the grand piano 18 wishes, optionally the mobile remote control 46 Press or the stationary signal generator 48 actuate. This recognizes the door drive control 42 as a wish, the wing 18 automatically open or - if the door, as in 4 shown, already opened - automatically close.

During a motor driven movement of the wing 18 monitors the door drive control 42 in automatic mode the power requirement of the electric motor 34 , Increases the force to be expended by the electric motor beyond a threshold, it can be concluded that the wing 18 against an obstacle or a person drives. The door drive 14 then stop the corresponding movement and reverse this to the wing 18 at least to go back a bit. This corresponding shutdown function or reversing function works with an automatic closing movement until shortly before the in 2 Shown final closing position. It can be accessed via the user interface 50 set a so-called reversing limit, which in 5 is indicated. For example, the force switching or reversing function works on the entire closing path until the closing edge 54 of the grand piano 18 still at a predetermined adjustable distance 56 - The reversing limit - is located by their position in the closing end position. The distance is eg slightly less than 50 mm.

You can with correspondingly small distance 56 assume that increasing the force when crossing the distance 56 through the stop of the wing 18 on the frame 20 or on the door seals is effected.

The distance 56 the reversing limit is preferably to be selected such that no body parts or other objects between closing wing 18 and frame 20 can be trapped.

In addition to the previously explained automatic mode is the door drive 14 but also set up the wing attached to it 18 is manually operated.

In 6 is a schematic block diagram of a possible embodiment of the door drive control 42 represented by function blocks. The corresponding devices indicated by the functional blocks can be, for example, by appropriate programming of a central processor unit of the door drive control 42 realize.

The door drive control 42 has an automatic mode control 58 for controlling the door drive in automatic mode. The automatic mode control 58 can be, for example, by the remote control 46 or the signal generator 58 activate, as by an automatic mode control command 60 is indicated. The automatic mode control 58 performs the above-explained automatic mode of the door drive 14 as he is well known for door drives, by the way.

The door drive control 42 further comprises a manual operation detecting means 62 for detecting a manual operation of the building door 10 on.

The manual operation detecting device 62 monitors, for example, the position sensor 40 and detects a manual operation when changing the position of the wing, without the electric motor 34 through the door drive control 42 would have been driven accordingly.

If a manual operation is detected, for example, a manual mode control 64 activated. Preferably, the door drive control 42 by default in manual mode except by an operator via auto switch 48 or remote control an automatic mode is activated. After performing the automatic movement then the door drive control returns 42 returns to manual mode, where the manual mode control 64 is active.

The manual mode control 64 switches the electric motor 34 so de-energized that the motor shaft 38 without increased resistance by force applied to the door drive arm 30 Passively turn. This allows a user the wing 18 open manually, for example, up to the in 4 illustrated opening position.

Next, the user can use the wing 18 from the in 4 Manually close the open position shown, as indicated by the arrow in 4 is indicated.

The manual mode control 64 has a closing movement detecting device 68 on, to a position transmitter 40 is connected and based on a movement of the position sensor 40 manual closing 66 of the grand piano 18 recognizes.

Next indicates the manual mode control 64 a closing end area detecting means 70 to capture if the wing 18 when closing manually in a closing end area 72 occurs near the closing end position. The closing end area 72 for example, corresponds to the distance 56 , which is set by the reversing limit.

Next indicates the manual mode control 64 a closing device 74 for automatically closing the wing 18 in his closing position.

The closing device 74 is with the closing end area detecting means 70 connected and formed so that it is detected when the wing 18 when closing manually 66 in the closing area 72 or, when the manual mode is active, not in the closing end position, but within the closing end range 72 located, the electric motor 34 such that it pulls the wing in the Schließendlage with a low moving speed, which is for example slower than a normal movement speed in the Normalbewegungsungsbereich outside the Reversiergrenze.

The wing 18 is by the closing device 74 - Similar to the automatic mode - motor in its attack against the frame 20 hazards; then the electric motor 34 switched off and reached, defined by the stop closing end position is a new reference value for a target Schließendlage in the door drive control 42 stored.

Because of this reference value is the closing end position and thus a point of movement of the wing 18 Always well known in manual mode, so that the door drive control due to the signals of the position sensor 40 can always reliably determine the door position using the reference value, even if the door drive gear 36 or the connections of the door drive arm 30 should still slip.

Thus, a play or slip within the through the engine and the door drive gear can be 36 including the connection to the driven door element.

By the closing device 74 In manual operation, a safe and comfortable closing of the building door is always possible 10 reached.
