Definitions

  • the present invention relates to a door system comprising a door with a leaf, a door closer for automatically closing the leaf, a closing force adjustment device for automatically adjusting the closing force of the door closer, and a control device for the closing force adjustment device.
  • the invention also relates to a method for operating such a door system.
  • Door closers are often an obstacle for disabled, old or young people because they make it difficult to open a door. However, door closers are necessary to ensure that doors close securely and thus secure critical fire protection sections.
  • the door closers are typically set to a high closing force so that the doors also close securely in wind or drafts, although this is only rarely required.
  • the invention solves the above-mentioned problems with a door closer according to claim 1, in particular in that a door closer of the type mentioned is used, in which a signaling device is additionally provided which is set up to emit a signal which indicates whether on the leaf an air pressure load is applied, which deviates from a predetermined air pressure load, and which is set up to adjust the closing force of the door closer as a function of the signal.
  • the predetermined air pressure load may have a value or range of values that corresponds to a normal air pressure load.
  • the predetermined air pressure load can in particular be zero or a range around zero.
  • the specified air pressure load can be specified, for example, as a range of values or as a maximum and/or minimum value.
  • the specified air pressure load can, for example, be stored in the control device by the manufacturer and/or can be specified subsequently, e.g. by a user or a service technician.
  • the door closer can be operated as a normal door closer and, if necessary, the closing force can be reduced or increased and adapted to the ambient conditions. Insofar as the closing force is adapted to the ambient conditions, one can also speak of an adaptive closing force adjustment.
  • the door system of the invention is particularly suitable for being able to comply with standard specifications with regard to opening force in stairwells with overpressure ventilation systems.
  • the adaptive closing force can also be set in particular as a function of the weather. For example, barrier-free access during normal operation and safe closing in windy conditions can be guaranteed.
  • the closing force of the door closer can also be automatically adjusted during assembly for the specified air pressure load or normal operation by means of the closing force adjustment device.
  • the invention allows a compact construction of the door closer and a comparatively inexpensive construction.
  • an air pressure load can be effective in the opening or in the closing direction.
  • the signal from the signaling device can also indicate, for example, whether the air pressure load is effective in the opening or closing direction.
  • the signaling device can have, for example, a sensor for the air pressure load, which determines whether the air pressure load on the wing differs from a predetermined air pressure load.
  • the sensor can also be set up to determine whether the air pressure load is effective in the opening or in the closing direction.
  • control device is set up to reduce the closing force of the door closer when an increased air pressure load is applied to the door leaf in the closing direction. This makes it easier to walk through the door in the event of an air pressure load.
  • the door system includes an overpressure ventilation system that exerts air pressure on the wing of the door when it is active, with the signal from the signaling device indicating whether the overpressure ventilation system is active or not. In this way, it can be ensured in a simple manner that the door can be opened with only little force, in particular with an opening force that conforms to standards, even when the overpressure ventilation system is active.
  • the signaling device can be formed, for example, by a fire alarm device.
  • a positive pressure ventilation system is due to a Fire alarm activated.
  • the fire alarm can therefore be used as such, for example, as a signal as to whether an air pressure load is present on the wing that deviates from the specified air pressure load.
  • the overpressure ventilation system itself can, for example, also output a corresponding signal or form a signaling device.
  • control device can be set up to reduce the closing force of the door closer when the overpressure ventilation system is active.
  • overpressure ventilation systems doors usually open into the stairwell, i. H. the positive pressure ventilation system creates an air pressure load on the sash in its closing direction.
  • the control device can alternatively be set up to increase the closing force of the door closer when the overpressure ventilation system is active. This ensures safe closing after the door has been passed.
  • overpressure ventilation systems can be controlled differently for different sections of the building.
  • a positive pressure ventilation system generates positive pressure in the stairwell.
  • the stairwell remains smoke-free. Escape doors on the upper and lower floors usually open into the stairwell against the overpressure. The exit from the stairwell on the ground floor to the outside opens up from the stairwell and closes against the overpressure.
  • the closing force is either increased or reduced. This can be configurable in the control unit during commissioning.
  • the system is intended for doors that lead into the stairwell, open against the air pressure in order to reduce the closing force to a minimum (EN3 according to EN1154) in the event of a fire.
  • the door closer according to the invention can therefore be arranged with particular advantage in a stairwell with a positive pressure ventilation system to keep smoke free.
  • the door closer preferably has a drive unit which can be controlled by a control device.
  • the drive unit is preferably connected to the door closer in such a way that it can influence, in particular reduce or increase, the opening or closing force of the door closer.
  • the control device is preferably connected to a control center in the building in such a way that in the event of a fire, for example, the control device receives a signal through which the control device instructs the drive unit to reduce the closing force of the door closer. In this way, fleeing people can flee the building through the stairwell without great effort.
  • the signal from the signaling device indicates whether there is wind in the vicinity of the door system or not and/or the wind strength in the vicinity of the door system. If there is wind in the area of the wing, a secure closing of the wing can be ensured in a simple manner.
  • the signaling device includes a wind sensor.
  • the wind sensor can, for example, be arranged directly by the door or outside on or on top of the building in which the door is arranged.
  • the signaling device can be set up to obtain information from a remote device, for example an Internet server, as to whether or not there is wind in the vicinity of the door system and/or the wind strength in the vicinity of the door system.
  • a remote device for example an Internet server
  • the information can be determined from online weather data.
  • the signaling device can, for example, form a central device or be part of one. Alternatively, the signaling device can also be integrated into the door closer and/or the control device, for example.
  • the door system in particular the door closer, the control device and/or the signaling device can preferably include a communication interface, in particular an Internet connection.
  • a communication interface in particular an Internet connection.
  • the signal from the signaling device a signal from a sensor for the air pressure load, a fire alarm signal, a wind signal and/or weather data can be transmitted via the communication interface.
  • control device is set up to increase the closing force of the door closer when there is wind or when the wind is above a predetermined value. This makes it easy to ensure that the door closes securely. With little or no wind, on the other hand, a low closing force can be set in order to enable the simplest possible, barrier-free access.
  • the closing force can also be adjusted depending on the direction of the air pressure load. For example, the closing force can be increased when there is wind in the opening direction and/or the closing force can be reduced when there is wind in the closing direction.
  • the door closer has a closer spring, with the closing force adjustment device being set up to adjust the prestressing of the closer spring in order to adjust the closing force of the door closer.
  • a closing force adjustment device can be constructed in a simple and compact manner.
  • the closer spring can be supported on a movable spring seat, with the prestressing of the spring being adjustable by the spring seat being moved.
  • the spring seat can be designed as a spring plate, for example.
  • the spring seat can be mounted in a housing of the door closer so that it cannot rotate and/or can be moved axially.
  • a structurally particularly simple embodiment provides that the closing force can be adjusted via a spindle mechanism, in particular by moving a spring seat via a spindle mechanism. It can advantageously be provided that the spindle mechanism converts a rotational movement of a spindle and/or a drive shaft into an axial movement of the spring seat.
  • the spindle mechanism has a trapezoidal thread. This allows the absorption of particularly high forces and a particularly high level of functional reliability.
  • a spindle of the spindle mechanism can be hollow, for example. Additional components of the door closer, for example, can be accommodated in the hollow spindle.
  • a further exemplary embodiment provides that the spindle mechanism comprises an end stop, in particular the end stop being assigned to a zero or reference position in the control device and/or the control device being set up to determine when the end stop has been reached. This allows the closing force adjustment device to be easily calibrated.
  • Reaching the end stop can be monitored or determined, for example, via the motor current of an electric motor driving the spindle mechanism.
  • the required motor current also decreases.
  • the current value of the preload can be determined at least approximately. If the motor current increases suddenly when the spindle mechanism is being moved, it can be deduced that the end stop or a zero or reference position has been reached. When the end stop or the zero or reference position is reached, the motor is preferably switched off.
  • the reaching of the end stop and/or a zero or reference position can be determined by means of a sensor.
  • a sensor can be designed, for example, as a reed switch, potentiometer, rotary encoder or the like.
  • the end stop can be provided with minimum prestressing or with maximum prestressing of a closer spring, or an end stop can advantageously also be provided with minimum and maximum prestressing.
  • the end stop is preferably designed with minimal preload. So the motor has enough reserves to easily overcome the detachment forces.
  • a drive spindle of the spindle mechanism is supported by an axial-radial bearing. This allows the drive spindle to be rotated with particularly little effort and high functional reliability.
  • An axial-radial bearing can absorb high forces, has a compact design and is easy to assemble, which reduces assembly costs.
  • the axial/radial bearing can be arranged, for example, on and/or in a component which closes a housing of the door closer. Such a component can form a bearing cap.
  • the axial-radial bearing can, for example, be pre-assembled in a bearing cover, which is fixed in the housing.
  • the end stop for the spindle mechanism or the spring seat can advantageously be used as an axial bearing point for the axial/radial bearing. In this way, an optimal transmission of force to the spindle can advantageously be ensured.
  • the drive spindle can preferably be sealed off from the environment by a sealing element between the spindle and the bearing cover.
  • a drive spindle of the spindle mechanism is mounted by means of a bearing, the bearing being arranged on and/or in a component, in particular a bearing cap, the spindle is driven by a motor, the motor being centered relative to the component by means of a centering.
  • the centering can comprise a centering collar on the component.
  • a recess corresponding to the centering collar can be provided on the engine, a transmission or another component provided between the engine and transmission, in particular transmission holder.
  • a reverse arrangement is also possible, ie a centering collar on the engine, transmission or other component, in particular the transmission holder, and a corresponding recess on the component, in particular the bearing cap.
  • the closing force adjustment device is driven by an electric motor.
  • a gear preferably a planetary gear, can preferably be provided between the electric motor and the closing force adjustment device.
  • the electric motor can preferably be designed as a geared motor, for example as a stepping motor with a planetary gear.
  • the drive spindle can preferably be aligned concentrically with the drive shaft and/or transmission output shaft.
  • the motor can be as large as possible and the connection from the drive spindle to the drive or transmission output shaft can be made very compact.
  • the drive spindle is preferably designed to be hollow towards the transmission output shaft, so that the drive spindle can accommodate the transmission output shaft.
  • the components can be connected to one another in a form-fitting manner, for example. This means that no additional, space-consuming coupling element is required between the drive spindle and the output shaft.
  • the door closer includes a drive unit, which includes the electric motor and the control device.
  • the drive unit can be flanged to a housing of the door closer, for example.
  • the signaling device can be set up, for example, to output the signal wirelessly and/or wired.
  • control electronics can have a Bluetooth, WLAN, and/or network module or the like, in order to be able to be controlled and/or networked via the building network or external devices.
  • tripping commands, parameterization and maintenance can be carried out flexibly.
  • the manual adjustment of the closing force of the door closer can also be dispensed with as a result. It can be provided, for example, that the fitter can simply enter the door size and weight in an app, whereupon the control electronics automatically set the appropriate closing force.
  • a networked door closer can also be informed about external influences such as fire alarms, weather, wind, traffic, etc. and react accordingly.
  • a permissible wind limit value is exceeded in the recorded online weather data, it can be provided, for example, that all door closers in the building adjust to an increased closing force in order to ensure secure closing.
  • a low closing force is preferably set in order to enable the simplest possible, barrier-free access.
  • the signaling device can be formed, for example, by a control center of the building or another unit remote from the door closer, such as a fire alarm device or an overpressure ventilation system. However, it can also be integrated in the door closer.
  • the control device of the closing force adjustment device can, for example, have its own power supply and/or be supplied with power via a control center of the building in which the door system is provided.
  • An exemplary embodiment provides that the closing force adjustment device has a mains power connection for the power supply.
  • a rechargeable battery can be provided to supply power to the closing force adjustment device.
  • the closing force adjustment device or the door closer can be operated safely and reliably even in the event of a power failure.
  • the rechargeable battery can be provided, for example, in a control center or in the door closer, in particular in a drive unit.
  • a rechargeable battery in the door closer or in the drive unit can in particular be optional.
  • the voltage of the rechargeable battery is lower than the voltage of an electric motor of the closing force adjustment device.
  • the battery advantageously has a low voltage of e.g. 3.7 V, which is lower than the motor voltage and allows a compact design due to the small number of cells.
  • the voltage is stepped up to a motor voltage, preferably 24 V, e.g. via a step-up converter, which can be arranged on the control electronics to save space. Overall, a very compact design of the door closer is achieved.
  • the object of the invention is also achieved by a method according to the independent claim directed thereto.
  • This method is for operating a door system, the door system comprising: a door with a wing, a door closer for automatic closing of the leaf, a closing force adjustment device for automatically adjusting the closing force of the door closer, and a control device for the closing force adjustment device; the method comprising the steps of: determining and/or indicating whether an air pressure load is applied to the wing which deviates from a predetermined air pressure load, adjusting the closing force of the door closer depending on whether an air pressure load is applied to the wing which differs from the predetermined air pressure load.
  • the door closer 10 comprises a housing 12 in which a mechanism of the door closer 10, which is described in more detail below, is accommodated.

  • the spring plate 18 is part of the closing force adjustment device and can be moved by means of the drive unit 16 and the actuating unit 14 . In normal operation, the spring plate 18 is preferably not moved, ie it is static.

  • the spindle 20 includes an end stop 44 for the in 2 visible spring plate 18. When the spring plate 18 rests against the end stop 44, this can form a zero or reference position, for example.
  • the end stop 44 forms an axial bearing point for the axial/radial bearing 42.
  • a sealing element 46 is provided between the spindle 20 and the bearing cap 22 .
  • a further sealing element 48 is provided between the bearing cap 22 and the housing 12 . The housing 12 is thus reliably sealed.
  • the spindle 20 has a recess 50 into which a drive shaft 52 of the geared motor 24 extends.
  • the drive shaft 52 forms an output shaft of the transmission 26.
  • the drive shaft 52 is positively coupled to the spindle 20, here via a feather key 54, for the transmission of a rotational movement.
  • the geared motor 24 is firmly connected to the gear holder 33 via screws 56 .
  • the gear holder 33 is also fixedly connected to the housing 12 via screws 58, as shown in FIG 4 emerges. This also shows a longitudinal section, but with the cutting plane compared to the 2 and 3 is rotated about the axis of the spindle 20 by 90°.
  • the geared motor 24 is aligned centrally to the bearing cover 22 via the gear holder 33 .
  • the bearing cap 22 has a centering collar 60 .
  • the gear holder 33 has a recess which corresponds to the centering collar 60 and is defined by an inner collar 62 .
  • the geared motor 26 also has a centering collar 64 .
  • the bearing cap 22 and the geared motor 26 are each inserted with their centering collar 60 or 64 into the recess of the gear holder 33, as a result of which the components are aligned exactly centrally with one another. This design enables particularly simple manufacture and precise and compact positioning of the components in relation to one another.
  • a centering collar could be designed on one side toward the bearing cap 22 on the gear holder 33 and the bearing cap 22 could have a recess into which the centering collar of the gear holder 33 can engage. The same applies to the centering between gear motor 24 and gear holder 33.
