Driving a swing door, comprising a door drive control according to one of the aforementioned embodiments.

According to a further aspect, the invention provides a swing door, comprising a frame, a rotary wing pivotably hinged to the frame about a lateral vertical axis, and such a door drive.

So far, the problem arises that when manually operating doors for buildings and structures, in particular swing doors, which are equipped with electric drives, reaching the door position "CLOSED" the door due to mechanical play of the drive system and / or the back pressure of the door seals not sealing is positioned in the door frame.

In a particularly preferred embodiment of the invention, a manual door movement in the direction of "DOOR CLOSED" is detected with the aid of a position transmitter If the driven door leaf is shortly before the end position "DOOR CLOSED" - in particular if a reversing limit of the motor-driven system is reached - the drive system switches on and seduces the door gently - ie, for example, at a lower speed - in the natural end position of the frame.

The door drive control is particularly preferably referenced after this process, whereby a consideration of the mechanical

Slippage or mechanical play of the drive system is corrected.

With particularly preferred embodiments, in particular one, several or all of the following advantages can be achieved:

a) preventing drafts,

b) correct latching of a door catch into a striking plate on the frame, c) reduction of the effort required for manual door closing, d) increase of the positioning accuracy of the drive by correction of the system slip.

An embodiment will be explained in more detail below with reference to the accompanying drawings. It shows:

Fig. 1 is an interior view of an automatically driven building door on

Example of a swing door with door drive;

Fig. 2 is a horizontal section along the line II-II of Fig. 1 in the

Closing end position "DOOR CLOSED";

Fig. 3 is a schematic block diagram of the construction of the door drive;

Fig. 4 is a view as in Fig. 2 with the door open, with a manual

Closing movement is initiated;

Fig. 5 is a view similar to Fig. 4 when closing the manual

Door, wherein the door is in a Schließendbereich shortly before reaching the Schließendlage; Fig. 6 is a schematic block diagram of a door drive control of the door drive shown in Fig. 3.

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

The building door 10 has a wing 18 formed here as a rotary wing 18 and a frame 20th

The rotary wing 16 is hinged by means of door hinges or door hinges 22 about a lateral vertical axis 24 pivotally mounted on the frame 20. The wing 18 is, as is well known in room doors or other building doors, with a door handle 26 for manually actuating a non-illustrated

Door lock equipped. By pressing the door handle 26 can (not shown) Türschnäpper from its closed position on a (not shown) strike plate of the frame 20 pull out so as to be able to open the wing 18 manually.

For optional automatic actuation of the door drive 14 is provided which has a door drive housing 28 and a motor-driven door drive arm 30. There are different types of mounting possible. For example, the door drive housing 28 could be mounted on the wing 18, wherein the free end of the Türantriebsarms 30 is fixedly connected in the frame 20. Shown is an example of a mounting, where the door drive housing 28 is fixedly secured in the region of the frame 20, and a free end of the

Door drive arm 30 is connected to the wing 18.

Also, different ways of connecting the door drive arm 30 are conceivable. In the illustrated example, a slide rail 32 is 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 type is a so-called Knickarmgestänge, wherein the door drive arm 30 forms a first rod member, the articulated to a second rod member is connected, which in turn is connected to its other end.

These aforementioned types of mounting are well known in door drives 14 for swing doors 12 and are not discussed here.

2 shows the building door 10 in horizontal section, with the sash 18 in its closing end position "DOOR CLOSED." The building door 10 is completely closed The sash 18 abuts against door seals (not shown), whereby the passage of draft air through the door Building door 10. In this final closing position of the wing 18 is held by the engaging on the strike plate of the frame 20 door catch.

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

The door drive 14 has an electric motor 34 which has a

Door drive gear 36 is coupled to the door drive arm 30 so geared that rotation of a motor shaft 38 of the electric motor 34 generates a movement of the Türantriebsarms 30 and vice versa movement of

Door drive arm 30 results in a rotation of the motor shaft 38 of the electric motor 34.

To the motor shaft 38, a position sensor 40 is connected.

The door drive gear 36 is positive fit, i. provided substantially slip-free or with little residual slip, so that on the motor shaft 38 by the position sensor 40, a position of the door drive arm 30 connected to the wing 18 can be detected.

Furthermore, the door drive 14 has a door drive control 42 for controlling the operation of the door drive 14.

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

Furthermore, a stationary signal generator 48 (or a stationary remote control) can be connected to the door drive control 42. The signal generator 48 may, as indicated, wired or also via a radio link with the

Door drive control 42 may be connected. The signal generator 48 can be actuated, for example, by means of keys of a person for actuating the door drive 14.

The door drive controller 42 further includes a user interface 50,

For example, with keyboard or select switches or slide switches, by means of which a user can make adjustments to the door drive control 42.

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

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

Further, the door drive controller 42 is connected to the electric motor 34 to drive the electric motor for automatically driving the wing 18.

Further, the door drive controller 42 is configured to detect the power demand of the electric motor 34. For example, for this purpose, the power consumption, the speed and / or the voltage or the current of the electric motor 34 is detected in order to obtain conclusions about the current expended force.

For example, the door drive control may be operated in an automatic mode to move the wing 18 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 the wing 18 wishes to operate either the mobile remote control 46 or press the stationary signal generator 48. This recognizes the

Door drive control 42 as a desire to open the wing 18 automatically or - if the door, as shown in Fig. 4, already open - automatically close.

During a motor-driven movement of the wing 18, the door drive control 42 monitors the power demand of the electric motor 34 in the automatic mode. If the force to be expended by the electric motor increases above a threshold, it can be concluded that the wing 18 is driving against an obstacle or a person , The door operator 14 then stops the corresponding movement and reverses this to at least partially back the wing 18. This corresponding shutdown function or

Reversing function works in an automatic closing movement until shortly before the closing end position shown in Fig. 2. It can be over the

Operator interface 50 set a so-called reversing limit, which is indicated in Fig. 5. For example, the power shutdown or

Reversing function on the entire closing path until the closing edge 54 of the wing 18 is still by a predetermined adjustable distance 56 - the reversing limit - from their position in the closing end position. The distance is e.g. a little less than 50 mm.

With a correspondingly small distance 56, it can be assumed that an increase in the force when the distance 56 is traveled over is effected by the abutment of the wing 18 on the frame 20 or on the door seals.

The distance 56 of 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 clamped.

In addition to the automatic mode explained above, however, the door drive 14 is also set up so that the wing 18 connected to it can be actuated manually. FIG. 6 shows a schematic block diagram of a possible exemplary embodiment of the door drive control 42 by means of function blocks. The corresponding ones indicated by the functional blocks

Devices can be realized, for example, by appropriate programming of a central processor unit of the door drive control 42.

The door drive controller 42 includes an automatic mode controller 58

Control of the door drive in automatic mode. The

Automatic mode control 58 can be activated, for example by the remote control 46 or the signal generator 58, as by a

Automatic mode control command 60 is indicated. The

Automatic mode control 58 performs the above-explained automatic mode of the door operator 14, as is otherwise well known in door drives.

The door drive controller 42 further has one

Manual operation detecting means 62 for detecting a manual operation of the building door 10.

The manual operation detection 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 controlled accordingly.

If a manual operation is detected, e.g. a manual mode control 64 is activated. Preferably, the door drive control 42 is standard in the

Manual mode, except that an automatic mode is activated by an operator via signal generator 48 or remote control. After performing the automatic movement, the door drive controller 42 then returns to the

Manual mode in which the manual mode control 64 is active.

The manual mode controller 64 de-energizes the electric motor 34 so that the motor shaft 38 can passively rotate without increased resistance to force applied to the door drive arm 30. This allows a user to open the wing 18 manually, for example, up to the opening position shown in Fig. 4. Further, the user can the wing 18 from that shown in Fig. 4

Close opening position manually, as indicated by the arrow in Fig. 4.

The manual mode controller 64 has a

Closing movement detection device 68 which is connected to a position sensor 40 and detects the manual closing 66 of the wing 18 based on a movement of the position sensor 40.

Further, the manual mode controller 64 has a

Closing end portion detecting means 70 for detecting whether the wing 18 when closing manually enters a Schließendbereich 72 near the closing end position, on. The closing end region 72 corresponds, for example, to the distance 56 which is set by the reversing limit.

Furthermore, the manual mode control 64 has a closing device 74 for automatically closing the wing 18 in its closing end position.

The closing device 74 is connected to the closing end area detecting device 70 and is configured to move when it detects that the wing 18 is moving into the closing end area 72 during manual closing 66 or not in the closing end position when the manual mode is active, but within the closing end area 72, the electric motor 34 is driven so that it is the wing with a low moving speed, for example, slower than a normal movement speed in the normal movement range outside the reversing limit, in the

Closing limit pulls.

The wing 18 is closed by the closing device 74 - similar to the

Automatic mode - motor driven into its stop against the frame 20; then the electric motor 34 is turned off and the reached, defined by the stop closing end position is stored as a new reference value for a target closing end position in the door drive control 42. Due to this reference value, the closing end position and thus a point of movement of the wing 18 is always well known even in manual mode, so that the door drive control can always reliably determine the door position using the signals from the position sensor 40 using the reference value, even if the door drive gear 36 or the connections of the door drive arm 30 should still have slippage.

Thus, play or slippage within the motor and door drive gear 36 including the connection to the driven door member can be corrected.

By Zuzieheinrichtung 74 a safe and comfortable closing of the building door 10 is always achieved even in manual operation.
