Description

Die Erfindung betrifft einen Türnotöffner, der für das Öffnen von Türen in Katastrophen- und Notfällen o.dgl. vorgesehen ist.The invention relates to an emergency door opener or the like for opening doors in disasters and emergencies. is provided.

In verschiedenen Industriebetrieben, Offshore-Bohrinseln u.dgl. sowie in Kraftwerken und Umspannstationen, Krankenhäusern, Anstalten und Institutionen verschiedener Art gibt es bestimmte, in Katastrophen und Notfällen zu benutzende Fluchtwege. Solche Fluchtwege sind mit Türen versehen, die von Innen ohne Schlüssel leicht zu öffnen sein sollen. Den für derartige Türen geltenden Vorschriften entsprechend müssen diese Türen u.a. nach Außen-auf gehen und von Innen mit einem Griff bzw. durch das Berühren mit dem Knie, dem Ellbogen oder irgendeinem anderen Körperteil zu öffnen sein. Zum Öffnen der hier genannten Arten von Türen werden sogenannte Türnotöffner benutzt, die abhängig von der Funktion verschiedenartig konzipiert sind. In various industrial companies, offshore drilling rigs and the like. as well as in power plants and substations, hospitals, institutions and institutions of various types, there are certain escape routes to be used in disasters and emergencies. Such escape routes are provided with doors that should be easy to open from the inside without a key. According to the regulations applicable to such doors, these doors must among other things go outside and open from the inside with a handle or by touching the knee, elbow or any other part of the body. So-called emergency door openers are used to open the types of doors mentioned here, which are designed differently depending on their function.

Eine bekannte Version des Türnotöffners besteht aus einer vertikal montierten Stange, einer sogenannten Druckstange, die normalerweise in zwei Gelenkhalterungen gelagert ist, die bei Druckeinfluß ermöglichen, daß die Druckstange etwas von der Türklinke und der der Wand zugewandten Türseite weggeschwenkt wird. Die Druckstange ist über ein sogenanntes Spannschloß gegliedert an der Türklinkenachse so befestigt, daß ein Wegschieben der Druckstange von der Türklinke ein Bewegen bzw. ein Drehen der Türklinke bewirkt, wobei die Schloßfalle eingezogen und die Tür dabei geöffnet wird. Ein Nachteil bei dieser Art von Türnotöffner ist es, daß die Türklinkenachse zur Befestigung des Spannschloßes mit einem durchgehenden Loch versehen sein muß, was die mechanischen Steuerungseigenschaften der Türklinkenachse beeinträchtigt.A known version of the emergency door opener consists of a vertically mounted rod, a so-called push rod, which is normally mounted in two articulated brackets which, when subjected to pressure, allow the push rod to be pivoted slightly away from the door handle and the side of the door facing the wall. The push rod is attached to the doorknob axis by means of a so-called turnbuckle so that pushing the push rod away from the doorknob causes movement or movement Turning the door handle causes the lock latch to be drawn in and the door to be opened. A disadvantage of this type of emergency door opener is that the door handle axis must be provided with a through hole for fastening the turnbuckle, which impairs the mechanical control properties of the door handle axis.

Der größere Nachteil besteht allerdings darin, daß die Türklinke selbst, die relativ hohen seitlich wirkenden Kräften ausgesetzt wird, nach einer gewissen Zeit verschleißt und dadurch ein zu großes Spiel aufweist. Zusätzlich werden alle mit dem Spannschloß verbundenen Glieder Verschleiß ausgesetzt werden. Der hier erwähnte. Verschleiß macht ein Nachstellen der betroffenen Teile des Türnotöffners erforderlich. Aufgrund der begrenzten Schwenkbarkeit der Druckstange wird die Druckstange auch nur im begrenzten Maße die Türklinke drehen können. Bei unsachgemäßem bzw. nicht vorgenommenen Nachstellen besteht die Gefahr, daß das Öffnen der Tür mit der Druckstange eventuell nicht möglich sein wird.The greater disadvantage, however, is that the door handle itself, which is exposed to relatively high lateral forces, wears out after a certain time and therefore has too much play. In addition, all links connected to the turnbuckle will be subject to wear. The one mentioned here. Wear makes it necessary to readjust the affected parts of the door emergency release. Due to the limited pivotability of the push rod, the push rod will only be able to turn the door handle to a limited extent. If the adjustment is improper or not carried out, there is a risk that it may not be possible to open the door with the push rod.

Bekannt ist ferner ein Türnotöffner, der ebenfalls aus einer vertikal montierten Druckstange besteht, die ebenfalls schwenkbar, allerdings Richtung Türklinke und der aufzuschlagenden Türseite gelagert ist. Diese Art von Türnotöffner ist mit einem Stift direkt an den Schloßkasten des Türschlosses angeschlossen. Die Übertragung der Bewegungen der Druckstange ist bei diesem Türnotöffnertyp verhältnismäßig kompliziert, und es kommen mehrere einstellbare Glieder vor.Also known is an emergency door opener which also consists of a vertically mounted push rod which is also pivotable, but is mounted in the direction of the door handle and the door side to be opened. This type of emergency door opener is connected directly to the lock case of the door lock with a pin. The transmission of the movements of the push rod is relatively complicated with this type of emergency door opener, and there are several adjustable links.

Ebenfalls bekannt sind verschiedene Typen von Türnotöffnern, bei denen die Druckstange horizontal montiert ist und die Druckstange auf der Öffnungsseite der Tür direkt schwenkbar über die Türklinke an einem Schloßkasten gelagert ist, der somit zu einer kompletten Türnotöffnereinheit gehört. Die horizontale Druckstange wird sich bei desem Typ von Türnotöffner in Schloßhöhe befinden, d.h. etwa einen Meter über dem Bodenniveau, und ist daher zur Benutzung in Situationen mit möglichen Verletzten, die aus verschiedenen Gründen nicht an die Druckstange herankommen können, ungeeignet. Dieser Typ Türnotöffner ist außerdem ebenfalls mit den oben beschriebenen Problemen behaftet.Also known are various types of emergency door openers in which the push rod is mounted horizontally and the push rod is pivotally mounted on the opening side of the door directly on the door handle on a lock case, which thus belongs to a complete door emergency release unit. The horizontal push rod will be located at the lock height of this type of emergency door release, ie about one meter above the floor level, and is therefore unsuitable for use in situations with possible injuries which for various reasons cannot reach the push rod. This type of emergency door opener also has the problems described above.

Der Erfindung liegt die Aufgabe zugrunde, eine einfache und funktionssichere Konstruktion eines Türnotöffners zu entwickeln, bei der die an den bisher bekannten Typen von Türnotöffnern haftenden Nachteilen im Wesentlichen eliminiert sind.The invention has for its object to develop a simple and reliable construction of an emergency door opener in which the disadvantages associated with the previously known types of emergency door openers are substantially eliminated.

Erfindungsgemäß wird die Aufgabe mit einem Türnotöffner gelöst, der aus einer an der Tür vertikal montierten Druckstange besteht, die in einem gewissen Abstand von der Tür in einer Befestigungseinrichtung an der Tür schwenkbar gelagert und bei Krafteinwirkung Richtung Tür schwenkbar ist. Der Türnotöffner ist dadurch gekennzeichnet, daß die Druckstange auf der zur Tür gewandten Seite mit einem Kraftübertragungselement versehen ist, das eine von der Stange Richtung Tür schräg aufwärts verlaufende Fläche aufweist, wobei die Fläche bei Betätigung der Druckstange an einer Türklinke angreift und die Türklinke in einer gleitendem Bewegung zum Öffnen der Tür hinunterdrückt. Vorzugsweise besteht das Kraftübertragungselement aus einem an der Druckstange aufgeschweißten Plattenelement.According to the invention, the object is achieved with a door emergency opener which consists of a push rod mounted vertically on the door, which is pivotably mounted at a certain distance from the door in a fastening device on the door and can be pivoted towards the door when force is applied. The door emergency opener is characterized in that the push rod on the side facing the door is provided with a force transmission element which has a surface which extends obliquely upwards from the rod towards the door, the surface engaging a door handle when the push rod is actuated and the door handle in one sliding movement to open the door. The force transmission element preferably consists of a plate element welded onto the pressure rod.

In vorteilhafter Weise erfordert diese Art von Türnotöffner normalerweise kein regelmäßiges Nachstellen. Durch die zweckmäßige Schrägung der Schrägfläche des Kraftübertragungselements ist auch bei Verschleiß und dadurch entstandenem Spiel in der Türklinke die einwandfreie Funktionssicherheit gewährleistet. Ein weiterer Vorteil bei dem Türnotöffner gemäß der Erfindung ist die äußerst einfache Herstellung und Montage dieses Türnotöffners. Er erfüllt außerdem sämtliche Forderungen, die heute an einen guten und zufriedenstellend funktionierenden Türnotöffner gestellt werden.Advantageously, this type of emergency door opener normally does not require regular readjustment. Due to the appropriate inclination of the inclined surface of the power transmission element, the perfect functional reliability is guaranteed even with wear and the resulting play in the door handle. Another advantage of the door emergency opener according to the invention is the extremely simple manufacture and assembly of this door emergency opener. It also fulfills all requirements be put to a good and satisfactorily functioning emergency door opener today.

Die Erfindung wird anhand der beigefügten Zeichnung, die eine Ausführungsform der Erfindung darstellt, näher erläutert.The invention is explained in more detail with reference to the accompanying drawing, which represents an embodiment of the invention.

Die Zeichnung stellt einen an einer Tür montierten Türnotöffner dar. Von der Tür ist nur eine Türfläche und eine Türklinke 6 gezeigt. Eine Druckstange 1 ist mittels Befestigungsstäben 2 und Halterungen 3 an der Tür befestigt. Die Halterungen 3 sind u.a. mit einem nicht dargestellten Federsystem versehen, das ein Zurückführen der Druckstange 1 bewirkt, wenn die Einwirkung auf die Druckstange 1 aufhört. Ein an der Druckstange 1 befestigtes Kraftübertragungselement 4 besteht aus einer sogenannten Schrägplatte, die mit einer Schrägfläche 5 und zwar mit dem oberen Teil davon, mit der Türklinke 6 in Berührung kommt, wenn die Druckstange 1 in Richtung Tür gedrückt wird. Wenn die Druckstange 1 allmählich immer näher an die Tür gedrückt wird, wird die Türklinke 6 in gleitender Berührung mit der abgeschrägten Fläche 5 hinuntergedrückt. Dadurch wird die Schloßfalle (nicht dargestellt) eingezogen und die Tür öffnet sich.The drawing shows a door emergency opener mounted on a door. Only one door surface and one door handle 6 are shown of the door. A push rod 1 is fastened to the door by means of fastening rods 2 and brackets 3. The brackets 3 include provided with a spring system, not shown, which causes the push rod 1 to be returned when the action on the push rod 1 ceases. A power transmission element 4 fastened to the push rod 1 consists of a so-called inclined plate, which comes into contact with the door handle 6 with an inclined surface 5, namely with the upper part thereof, when the push rod 1 is pressed towards the door. When the push rod 1 is gradually pressed closer to the door, the door handle 6 is pressed down in sliding contact with the tapered surface 5. This pulls in the lock latch (not shown) and the door opens.
