Definitions

  • the present invention relates to a door operator for a security door, such as a fire or smoke door, comprising: an electric drive unit, in particular an electric motor, for electrically driving a movable door leaf of the safety door, a connectable to the electric drive unit control unit for outputting electric power to the electric drive unit, a mechanical energy storage for storing potential energy, in particular a spring arrangement, which with so the door can be coupled, that in an opening movement of the door power is loaded into the energy storage and a closing movement of the door wing is supported while releasing energy of the energy storage, and a fault reporting device, which is designed to be in the presence of an accident criterion, especially in case of fire, a cause electrical separation of the drive unit of the control unit to prevent electrical drive of the door and closing the door when the door is not closed ls bring about by means of mechanical energy storage.
  • an electric drive unit in particular an electric motor
  • a connectable to the electric drive unit control unit for outputting electric power to the electric drive unit
  • a mechanical energy storage for
  • Such door drives are used, for example, to automatically close fire doors in case of fire to counteract a spread of the fire. Due to the mechanical energy storage, it is ensured that the closing of the door leaf also takes place in the event of a mains power failure.
  • a mechanical energy storage a spring arrangement, a rubber cord or similar means for storing potential energy can be used.
  • the accident reporting device may in particular be a simple fire detector.
  • the electrical separation of the drive unit from the control unit is caused in the event of an alarm for safety reasons, in particular to prevent unwanted opening of the door leaf and to allow the mechanical energy storage, an electroless closing of the door leaf, if the door is not yet closed.
  • the door leaf Upon demand closing, the door leaf is held in the closed position by the mechanical energy storage independent of the power supply and any control signals.
  • This is fundamentally desirable in terms of the safety door's protective function, but presents a problem in that escaping persons are obstructed.
  • the door wings are often relatively heavy, so that the corresponding mechanical energy storage must exert a high clamping force.
  • security doors of the type mentioned are generally not suitable for barrier-free building.
  • an electrical opening of the door leaf in the event of escape separates in such door drives from the principle, since the control unit has no access to the electric drive unit in case of failure.
  • a door drive according to the invention comprises a drive activation module, which is able to temporarily bridge a separation of the drive unit triggered by the accident reporting device from the control unit. Due to the bridging, the control unit still has access to the electric drive unit even after a reported accident for a certain period of time.
  • the door can thus be opened electrically on arrival of a fleeing person or the manual opening of the door leaf can be electrically supported - which is referred to in the art as "servo operation". In this way, even weak or disabled persons can pass the security door without difficulty during an escape.
  • the basic protective function of the security door is ensured by the fact that the bridging of the electrical separation between the drive unit and the control unit takes place only temporarily and not permanently.
  • An embodiment of the invention provides that the drive activation module is connected to the control unit and is designed to bring about during the bridging of the separation of the drive unit of the control unit, in particular one-time, opening movement of the door by the electric drive unit. A person arriving at the closed security door is automatically let through, as it were, which is particularly helpful in the event of a panic.
  • the drive activation module can be designed to bring about a closing movement of the door leaf by the electric drive unit after the opening movement has been brought about. This way, the door will open after the Passing a fleeing person automatically returns to the security state.
  • the electrical separation of the control unit from the electric drive unit preferably takes place only after the one-time electrical opening and closing operation.
  • the drive activation module comprises an electronic timer, in particular a capacitor, a counter module, a digital clock and / or a microcontroller, or a mechanical timer, in particular a mechanical clock, for specifying the period of the temporary bridging.
  • the electronic timer or the mechanical timer ensure that the bridging is not uncontrolled, but only during a fixed period of time.
  • the drive activation module may be designed to end the bridging immediately after the expiration of the time period predetermined by the electronic timer or by the mechanical timer. As a result, impairment of the safety function of the door by the drive activation module is reliably prevented.
  • the drive activation module may be configured to bridge any separation of the drive unit triggered by the accident reporting device from the control unit for a predetermined period of time.
  • the drive activation module may be designed to generally delay the separation of the drive unit from the control unit in the event of a fault. As a matter of principle, there is still time for escaping people to pass the security door without difficulty after a triggered alarm.
  • An alternative embodiment of the invention provides that the drive activation module has a signal input and is designed to bridge a separation of the drive unit from the control unit only upon application of an activation signal at the signal input. In this embodiment, the bridging of the electrical separation is therefore only as needed.
  • the signal input may be coupled to an actuator and / or to a rescue route safety sensor. In this way, the presence of escaping persons at the security door can be reported to the drive activation module.
  • a switch connected to the signal input could be provided which monitors the position of a door handle of the door leaf.
  • a corresponding radio transmitter could also be provided.
  • the signal input can be edge-triggered.
  • the bridging of the electrical isolation can then be triggered again only by a further edge at the signal input. An undesirable permanent bridging due to a continuous control at the signal input is thus avoided.
  • a further embodiment of the invention provides that the electric drive unit can be connected via a supply circuit to the control unit, in which a relay is provided, wherein the accident reporting device has a NC contact, which is provided in the control current path of the relay to the relay in the presence of the fault criterion and that the drive activation module has a bypass switch contact connected in parallel with the normally closed contact.
  • a door drive according to the invention is particularly simple and inexpensive.
  • the control unit may have a test input to which the drive activation module can be connected in order to enable a functional test of the drive activation module by the control unit.
  • a possible malfunction of the drive activation module can be detected quickly and easily.
  • appropriate measures for indicating or correcting the malfunction can be initiated.
  • the control unit can be designed to trigger one or no electrical disconnection of the drive unit from the control unit, even if the accident criterion is present, depending on which fault criterion is prioritized.
  • the drive activation module may be integrated in the control unit.
  • the electronic components of the control unit and the electronic components of the drive activation module can be arranged on the same circuit board.
  • the drive activation module can be designed as a separate module from the control unit, which is preferably connectable via a connector connection with the control unit.
  • the invention also relates to a security door, in particular a fire or smoke protection door, with a door which is movable relative to a door frame between an open position and a closed position, and a door drive which is coupled via a coupling element with the door to an automatic movement of the To allow door leaf.
  • the door drive is designed as described above. Such a security door can be passed in the event of danger, even by weak or disabled persons without difficulty.
  • Fig. 1 shows a conventional fire door 11, which includes a movable door wing 15.
  • the door leaf 15 may be rotatable or displaceable relative to a window frame, a guide or the like.
  • the fire door 11 could also include a plurality of door wings 15, for example, two oppositely displaceable door 15.
  • an actuator (not shown) may be provided in the form of a handle or a door handle, by means of which a user can open the door 15 manually .
  • the fire door 11 can also be designed for completely automatic operation, for example using proximity sensors, and accordingly be designed without an actuating element.
  • a door drive 19 which comprises an electric drive unit 21, here in the form of an electric motor.
  • the electric drive unit 21 is coupled via a not shown in detail coupling element with the door leaf 15 so that it is electrically driven.
  • the electric drive unit 21 could also be designed only for a servo operation in which no independent opening of the door leaf 15 by means of the electric drive unit 21 is possible, but only a manual opening of the door leaf 15 is supported.
  • the door drive 19 further comprises a mechanical energy storage 23, which is also coupled to the door leaf 15.
  • the mechanical energy storage 23 may be executed in a basically known manner as a simple spring arrangement. When the door leaf 15 is opened, the spring arrangement is tensioned, that is, potential energy is stored in the mechanical energy storage 23. A closing movement of the door leaf 15 is supported while releasing energy of the mechanical energy storage device 23.
  • an electronic control unit 25 which comprises a microcontroller 27, a motor driver 29 and a motor relay 30.
  • the normally open motor relay 30 is arranged in a supply circuit 31, which connects the electric drive unit 21 with the motor driver 29.
  • a fault signaling device in the form of a fire detector 35 is provided, which has a ⁇ ffnertitle 37. In the absence of an accident is the NC contact 37 as well as the normally open contact 34 of the motor relay 30 is closed.
  • the NC contact 37 is opened, whereby the normally open contact 34 of the motor relay 30 opens.
  • the electronic control unit 25 is then disconnected from the electric drive unit 21. Accordingly, any electrical driving of the door leaf 15 is omitted. If the door leaf 15 is not yet closed, the mechanical energy storage 23 ensures that the door leaf 15 is moved into the closed position.
  • the door drive 19 'of in Fig. 2 illustrated fire door 11 'according to the invention is therefore equipped with an activation module 40 which is able to temporarily bridge a triggered by the fire detector 35 separation of the electric drive unit 21 of the control unit 25'.
  • an activation module 40 which is able to temporarily bridge a triggered by the fire detector 35 separation of the electric drive unit 21 of the control unit 25'.
  • the drive activation module 40 includes a bypass switch contact 41 which is connected in parallel with the normally closed contact 37 of the fire detector 35. Further Drive activation module 40 includes an electronic timer 45 coupled to a signal input 47 of drive activation module 40.
  • the signal input 47 may be coupled to an actuator of the door panel 15 and / or to an escape route safety sensor (both not shown).
  • the bridging switch contact 41 is closed and the electronic timer 45 is started. A demoriggern can only be done by a new edge on the signal input 47.
  • the lock-up switching contact 41 is closed for a time period predetermined by the electronic timer 45. Accordingly, the opener NC contact 37 of the fire detector 35 is bridged for the relevant period of time.
  • the control unit 25 For the given period of time, the control unit 25 'has full access to the electric drive unit 21. Furthermore, the microcontroller 27' of the control unit 25 'is connected via a control line 48 to the signal input 47 of the drive activation module 40 and configured to perform a one-time opening movement and a subsequent closing movement of the door leaf 15 by the electric drive unit 21, while the NC contact 37 is bridged. After the predetermined period of time, the bypass switch contact 41 and thus the normally open contact 34 of the motor relay 30 opens. The safety state of the fire door 11 ', in which the movable door 15 is separated from the electric drive unit 21 and is acted upon exclusively by the mechanical energy storage 23, is then restored. However, a new bridging can be triggered again at any time by a further edge at the signal input 47.
  • the drive activation module 40 could also be designed to bridge any separation of the drive unit 21 initiated by the fire detector 35 from the control unit 25 'for a predetermined period of time.
  • the drive activation module 40 would not necessarily have to be provided with a signal input 47 in this case.
  • the control unit 25 ' has a test input 50 which is connected to the drive activation module 40 via a test line 55.
  • the test input 50 enables a functional test of the drive activation module 40 by the control unit 25 '.
