Description
Die vorliegende Erfindung befasst sich mit einer Notraffvorrichtung für Sonnenschutzanlagen mit einem raff- oder wickelbaren Behang, wobei ein Energiespeicher, z. B. eine Federspannvorrichtung, vorgesehen ist, der in einem vorgespannten Zustand mittels einer Auslösevorrichtung blockiert ist und nach der Freigabe durch die Auslösevorrichtung den Behang mit hoher Geschwindigkeit einholt, wobei die Auslösevorrichtung ein elektrisches Stellglied aufweist, das durch ein elektrisches Signal zur Freigabe des wenigstens einen aufgeladenen oder vorgespannten Energiespeichers ansteuerbar ist.The present invention is concerned with a Notraffvorrichtung for sun protection systems with a raff- or windable curtain, wherein an energy storage, for. B. is provided a spring tensioning device, which is blocked in a prestressed state by means of a triggering device and after the release by the triggering device recovers the curtain at high speed, wherein the triggering device comprises an electric actuator, which by an electrical signal for releasing the at least one charged or biased energy storage is controlled.

Schließlich ist auch die Montage des Bowdenzuges oder einer sonstigen mechanischen Ausrüstung zur Betätigung der Auslösevorrichtung aufwendig.Finally, the assembly of the Bowden cable or other mechanical equipment for actuating the triggering device is complicated.
Eine Notraffvorrichtung der eingangs genannten Art ist aus der
Die Aufgabe der vorliegenden Erfindung besteht darin, eine Notraffvorrichtung zu schaffen, die die Nachteile bekannter Auslösevorrichtungen vermeidet.The object of the present invention is to provide a Notraffvorrichtung which avoids the disadvantages of known tripping devices.
Erfindungsgemäß wird die Aufgabe durch eine Notraffvorrichtung der eingangs beschriebenen Art gelöst, bei welcher eine Notstromversorgung vorgesehen ist, die das elektrische Stellglied mit Strom versorgt und bei einem Stromausfall das elektrische Signal generiert.According to the invention the object is achieved by a Notraffvorrichtung of the type described above, in which a Emergency power supply is provided which supplies the electric actuator with power and generates the electrical signal in case of power failure.
Eine solche Ausgestaltung ist zum einen vorteilhaft, wenn es bei einem schweren Gebäudeschaden zu einem Stromausfall kommen sollte, kann aber auch in anderen Situationen vorteilhaft sein. Wenn beispielsweise ein Raum verdunkelt ist und es zu einem Stromausfall kommt, wird durch das dennoch mögliche sofortige Aufholen der Verdunklungsbehänge der Raum erhellt und es kann keine Paniksituation bei den im Raum befindlichen Personen auftreten.Such an embodiment is advantageous on the one hand, if a power failure should occur in the case of a severe building damage, but can also be advantageous in other situations. For example, if a room is darkened and there is a power outage, the possible immediate recovery of the blackout hangings illuminates the room and there can be no panic in the room.
Neben den bereits anfangs genannten Energiespeichern in der Form von Federspannvorrichtungen, beispielsweise als Torsionsfederpakete oder Gasdruckfedern, sind auch weitere Formen von Energiespeichern möglich, beispielsweise pneumatische oder hydraulische Antriebe oder auch angehobene Gewichte, die im Notfall den Behang der Anlage raffen können.In addition to the already mentioned initially energy storage in the form of spring tensioning devices, such as Torsionsfederpakete or gas springs, other forms of energy storage are possible, such as pneumatic or hydraulic drives or raised weights that can gather the curtain of the system in an emergency.
Während im einfachsten Fall die Erzeugung des elektrischen Schaltsignals mittelseines manuell betätigbaren Betätigungsschalters oder -tasters erfolgt, wobei ein solcher Schalter oder Taster zur Vergrößerung der Hemmschwelle gegen eine bewusste Fehlauslösung ähnlich wie Schalter zur Betätigung eines Feueralarms hinter einer dünnen Glasscheibe angeordnet werden kann, ist einer weiteren Ausführungsform der Erfindung, ein Rauch- oder Brandmelder oder ein Temperatursensor vorgesehen, der bei seinem Auslösen das elektrische Signal generiert. Bei einer solchen Ausbildung der Notraffvorrichtung ist nicht unbedingt ein manueller Eingriff im Gefahrenfall notwendig, da die Sicherheitsüberwachung in dem Gebäude die Notraffvorrichtung selbsttätig auslösen kann. Auch kann alternativ oder ergänzend eine Rauch-/Wärmeabzugsanlage vorgesehen sein, die bei Inbetriebnahme das elektrische Signal generiert und, sofern dies gewünscht ist, kann auch ein Bewegungsmelder vorgesehen sein, um das betreffende elektrische Signal zum Auslösen der Notraffvorrichtung zu generieren.While in the simplest case, the generation of the electrical switching signal by means of a manually operable control switch or pushbutton, such a switch or button to increase the inhibition threshold against deliberate false triggering similar to switches for operating a fire alarm can be placed behind a thin glass plate is another Embodiment of the invention, a smoke or fire detector or a temperature sensor is provided which generates the electrical signal when it is triggered. In such a training of Notraffvorrichtung a manual intervention in case of danger is not necessarily necessary because the security monitoring in the building the emergency device can trigger automatically. Also, as an alternative or in addition, a smoke / heat exhaust system may be provided which generates the electrical signal during startup and, if desired, a motion detector may be provided to generate the relevant electrical signal to trigger the Notraffvorrichtung.
Eine weitere vorteilhafte Ausbildung sieht vor, dass ein Windsensor vorgesehen ist, der das elektrische Signal beim Erreichen eines Grenzwertes der Windgeschwindigkeit generiert. Bei einer solchen Ausbildung wird eine Beschädigung des ausgefahrenen Behanges durch übermäßige Windbelastung vermieden, wobei die Nutzung der Notraffvorrichtung aufgrund der elektrischen Auslösevorrichtung auch bei im übrigen rein mechanisch betriebenen Sonnenschutzanlagen möglich ist. Selbstverständlich ist bei einer solchen Ausgestaltung die Sonnenschutzanlage mit der Notraffvorrichtung so auszulegen, dass eine Beschädigung der Anlage durch das Auslösen der Notraffvorrichtung in jedem Fall vermieden wird.A further advantageous embodiment provides that a wind sensor is provided which generates the electrical signal upon reaching a limit value of the wind speed. In such a design damage to the extended curtain is avoided by excessive wind load, the use of Notraffvorrichtung due to the electrical release device is also possible in the otherwise purely mechanically operated sunshade systems. Of course, in such an embodiment, the sunshade system with the Notraffvorrichtung designed so that damage to the system by triggering the Notraffvorrichtung is avoided in any case.
Die erfindungsgemäße Notraffvorrichtung, wie sie zuvor beschrieben worden ist, eignet sich auch zum Einsatz in einem System zur Freigabe von Fluchtwegen mit einer Steuerzentrale und mehreren Notraffvorrichtungen dieser Art. In einem solchen Fall kann die Steuerzentrale das elektrische Signal zum Auslösen bestimmter Notraffvorrichtungen oder aller Notraffvorrichtungen generieren. Die Auslösung einzelner Anlagen kann beispielsweise bei einem teilweisen Stromausfall in einem Gebäude oder bei Anlagen auf der Windangriffseite des Gebäudes sinnvoll sein, wenn ein entsprechendes Signal eines Windsensors vorliegt. Im Brandfall kann die Zentrale aber auch das rasche Aufholen aller Anlagen durch Betätigen aller Notraffvorrichtungen veranlassen.The emergency rammer according to the invention, as described above, is also suitable for use in a system for releasing escape routes with a central control unit and several emergency ramming devices of this type. In such a case, the central control unit can generate the electrical signal for triggering certain emergency raid devices or all emergency raid devices , The triggering of individual systems may be useful, for example, in the case of a partial power failure in a building or in installations on the wind attack side of the building, if a corresponding signal of a wind sensor is present. In case of fire, the head office but also prompt the rapid recovery of all systems by pressing all Notraffvorrichtungen.
Das elektrische Stellglied kann bei den jeweiligen Notraffvorrichtungen unmittelbar dem Energiespeicher zugeordnet sein, wobei beispielsweise eine Federspannvorrichtung auf eine Welle wirkt, auf der ein Rastelement drehstarr angeordnet ist, das mit einem beweglichen Verriegelungselement zusammenwirkt, das mit dem elektrischen Stellglied gekoppelt ist und durch dieses aus dem Eingriff mit dem Rastelement ausrückbar ist. Die Ausbildung über ein bewegliches Rastelement bietet den Vorteil, dass im Normalfall das elektrische Stellglied nicht bestromt werden muss, um die Federspannvorrichtung in der vorgespannten Stellung zu halten, grundsätzlich sind aber auch andere Ausführungsformen von Stellgliedern und andere Formen der Arretierung der Federspannvorrichtung möglich.The electric actuator may be associated with the respective Notraffvorrichtungen directly to the energy storage, for example, a spring tensioning device acts on a shaft on which a locking element is rotationally fixed, which cooperates with a movable locking element which is coupled to the electric actuator and through this from the Engagement with the locking element can be disengaged. The training on a movable locking element has the advantage that normally the electric actuator does not need to be energized to keep the spring tensioning device in the biased position, but in principle other embodiments of actuators and other forms of locking the spring tensioning device are possible.

Das Stellglied 20 wird durch externe Signale aktiviert. In
Das externe Signal kann auch durch Sensoren generiert werden, die ungewöhnliche Ereignisse in einem Gebäude detektieren und damit eine Notfallsituation erfassen können. Beispiele für solche Sensoren sind ein Rauchsensor 26, eine Brandmeldeanlage 28, ein Bewegungssensor 30, ein Temperatursensor 32 oder auch eine Rauch-/Wärmeabzugsanlage, die bei ihrem Einschalten ein externes Signal generiert. Die Auslösung des Stellgliedes kann auch mittels einer Stromüberwachung 34 erfolgen, die im Falle eines Stromausfalls das Stellglied 20 betätigt, wobei das Stellglied 20 auch so aufgebaut sein kann, dass es im Regelfall bei Anliegen der Netzspannung die Notraffeinrichtung blockiert und diese dann bei Wegfall der Netzspannung freigibt. Die Stromüberwachung 34 kann auch eine Notstromversorgung beiinhalten und, falls gewünscht, das Stellglied 20 z. B. bei einem Stromausfall aktiv auslösen.The external signal can also be generated by sensors that can detect unusual events in a building and thus capture an emergency situation. Examples of such sensors are a
Ferner besteht auch die Möglichkeit, sämtliche Notraffvorrichtungen innerhalb eines Gebäudes zentral von einer Steuerzentrale 36 aus anzusteuern. Auf diese Weise ist es möglich, dass bei Auslösen eines Feueralarms in einem Gebäude oder Ansprechen eines Rauchsensors auf einer Etage über die Steuerzentrale 36 dann die notwendigen Maßnahmen veranlasst werden, um alle relevanten Fluchtwege 18 freizugeben. In einem solchen Fall ist es auch möglich, die Steuerzentrale 36 den zuvor beschriebenen Sensoren zwischenzuschalten, d. h. das Stellglied 20 wird nicht unmittelbar durch die Sensoren ausgelöst, sondern deren Signale werden in der Steuerzentrale 36 verarbeitet, um dann die relevanten Stellglieder 20 anzusteuern und die entsprechenden Notraffvorrichtungen auszulösen.Furthermore, it is also possible to control all Notraffvorrichtungen within a building centrally from a control center 36 from. In this way it is possible that when triggering a fire alarm in a building or response of a smoke sensor on a floor via the control center 36 then the necessary measures are taken to release all
