Description

Die Erfindung betrifft einen Türöffner entsprechend des Oberbegriffes des Hauptanspruches.The invention relates to a door opener according to the preamble of the main claim.

Türöffner mit einem Antrieb werden z. B. dort verwendet, wo große Türen zu öffnen sind bzw. wo behinderte Personen Türen zu öffnen haben, d. h. zum Beispiel im Krankenhausbereich, z. B. in öffentlichen Gebäuden und dergleichen. Dabei weisen die Türöffner einen Antrieb auf, z. B. einen hydraulischen Antrieb oder einen Elektroantrieb, und bei Betätigung z. B. eines Schalters öffnet die Tür und schließt anschließend wieder.Door openers with a drive are e.g. B. used where large doors have to be opened or where disabled people have doors have to open, d. H. for example in the hospital area, z. B. in public buildings and the like. Show the door opener has a drive, e.g. B. a hydraulic drive or an electric drive, and when actuated z. B. one Switch opens the door and then closes again.

Dabei ist es eine gesetzliche Vorschrift, daß der Schließvorgang der Tür auch dann erfolgt, wenn die Stromversorgung zusammenbricht, z. B. im Brandfall, und bei dem Einbruch der Stromversorgung ist dann eine geschlossene Tür manuell zu öffnen. Dieses manuelle Öffnen ist jedoch bei den bekannten Türöffnern mit einem nicht unerheblichen Kraftaufwand verbunden, denn beim Öffnen der Tür wird manuell nicht nur gegen die Schließfeder des Türöffners Kraft aufgewandt, sondern beim manuellen Öffnen der Tür wird die Öffnungsbewegung auf sämtliche Teile des Türöffners mit übertragen, d. h. beim manuellen Öffnen der Tür wird sowohl die Schließfeder des Türöffners als auch der eigentliche Antrieb bewegt, was im Notfall problematisch sein kann, wenn z. B. eine behinderte Person beim Brand innerhalb eines Gebäudes eine verschlossene Tür aufziehen möchte und nicht die erforderliche Kraft dazu manuell aufbringen kann. Noch verstärkt wird dieses Problem durch die häufig in Türöffnern verwandten Getriebe, die ebenfalls beim manuellen Aufziehen der Tür mitbewegt werden müssen und hierdurch den dazu benötigten Kraftaufwand deutlich erhöhen.It is a legal requirement that the closing process the door occurs even when the power supply breaks down, z. B. in the event of fire, and when the power supply drops then a closed door must be opened manually. However, this manual opening is in the known door openers associated with a not inconsiderable effort, because when the door is opened, it is not only manual against the closing spring the door opener used force, but manual Opening the door will open the opening movement on all parts with the door opener transferred, d. H. when opening the The door becomes both the closing spring of the door opener and the Actual drive moves, which can be problematic in an emergency can if z. B. a disabled person in the fire within wants to open a locked door of a building and cannot apply the required force manually. This problem is exacerbated by the frequent use of door openers related gears, which are also used for manual winding the door must be moved and thereby the significantly increase the effort required.

Der Erfindung liegt die Aufgabe zugrunde, einen Türöffner derart auszubilden, daß er zum einen mittels eines Antriebes die Öffnung einer Tür ermöglicht und der darüber hinaus bei einem manuellen Öffnen der Tür die dazu notwendigen'Kräfte deutlich reduziert.The invention has for its object a door opener like this to train that he the opening by means of a drive allows one door and also one manual opening of the door clearly shows the necessary forces reduced.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des kennzeichnenden Teiles des Hauptanspruches gelöst.This object of the invention is achieved by Doctrine of the characterizing part of the main claim solved.

Mit anderen Worten ausgedrückt wird ein Türöffner vorgeschlagen, der ein Verbindungselement beinhaltet, das dann, wenn ein Kraftfluß vom Antrieb zur Tür stattfindet, eine Verbindung zwischen Antrieb und der zu öffnenden Tür herstellt, das jedoch in dem Fall, daß ein Kraftfluß von der zu öffnenden Tür zum Antrieb stattfindet, eine Entkoppelung der zu öffnenden Tür zumindest von dem Antrieb ermöglicht, um hierdurch die aufzubringenden Kräfte für das manuelle Öffnen der Tür deutlich zu reduzieren.In other words, a door opener is suggested which contains a connecting element which, when a Power flow from the drive to the door takes place, a connection between Drive and the door to be opened, but in in the event that a power flow from the door to be opened to the drive takes place, at least a decoupling of the door to be opened enabled by the drive to thereby apply the Forces for manually opening the door significantly to reduce.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen erläutert.Advantageous embodiments of the invention are in the subclaims explained.

In vorteilhafter Ausgestaltung ist der Antrieb mit einem Getriebe verbunden, um durch den Einsatz des Getriebes einen kleineren Antriebsmotor wählen zu können, wobei das Verbindungselement in vorteilhafter Ausgestaltung zwischen Getriebe und der zu öffnenden Tür angeordnet ist, um eine Entkoppelung dessen manuellen Türöffnungsvorganges von dem Getriebe zu erreichen.In an advantageous embodiment, the drive is with a gear connected to a smaller one by using the gearbox To be able to choose the drive motor, the connecting element in an advantageous embodiment between the transmission and opening door is arranged to decouple it manual door opening process from the gearbox.

In vorteilhafter Ausgestaltung ist der Antrieb mit einem Lineargetriebe ausgebildet, um durch diese Getriebeart eine vorteilhafte Kraftübertragung zwischen Antrieb und zu öffnender Tür zu erhalten und um hierdurch wiederum einen besonders kleinen Antrieb verwenden zu können, wobei der Antrieb z. B. hydraulisch bzw. elektronisch erfolgen kann.In an advantageous embodiment, the drive is with a linear gear trained to be advantageous by this type of gear To receive power transmission between the operator and the door to be opened and, in turn, a particularly small drive To be able to use, the drive z. B. hydraulic or can be done electronically.

In vorteilhafter Ausgestaltung besteht das Verbindungselement aus einem antriebsseitigen Körper und einem türseitigen Körper, die bei einem in Richtung der Tür gerichteten Kraftfluß miteinander gekoppelt sind und die bei einem in Richtung des Antriebes gerichteten Kraftfluß in eine einander freigebende Position verbringbar sind.In an advantageous embodiment, the connecting element from a drive-side body and a door-side body, the power flow towards each other in the direction of the door are coupled and in the direction of the drive directed power flow in a releasing position are spendable.

In vorteilhafter Ausgestaltung besteht das Verbindungselement aus einer antriebsseitigen Zugstange und einem türseitigen Pleuel, die teleskopierbar miteinander ausgebildet sind, wobei eines dieser Elemente ein Langloch aufweist, in dem ein Vorsprung des anderen Elementes geführt ist, wobei das Langloch die Beweglichkeit des Vorsprunges begrenzend ausgebildet ist. Das heißt, daß der Vorsprung in der Pleuelstange ausgebildet ist, und das Langloch (oder Nut) in der Zugstange, oder umgekehrt.In an advantageous embodiment, the connecting element from a drive-side pull rod and a door-side Connecting rods that are designed to be telescopic with one another, wherein one of these elements has an elongated hole in which a projection the other element is guided, the elongated hole the mobility of the projection is limited. That is, the protrusion is formed in the connecting rod and the elongated hole (or groove) in the drawbar, or vice versa.

Eine einfache Ausführbarkeit der Erfindung wird dann erreicht, wenn in dem türseitigen Pleuel ein hervorstehender Splint angeordnet ist, der in dem in der Zugstange ausgebildeten Langloch beweglich geführt ist.A simple feasibility of the invention is then achieved if a protruding cotter pin is arranged in the connecting rod on the door side is that in the elongated hole formed in the drawbar is movably guided.

Ein Ausführungsbeispiel der Erfindung wird in den Zeichnungen dargestellt, wobei

Fig. 2
represents a partially sectioned side view of the door opener from FIG. 1.

Bezugnehmend auf die Figuren besteht ein Türöffner 1 aus einem nur ansatzweise dargestellten Antrieb 2, der in diesem Ausführungsbeispiel als Elektromotor ausgebildet ist. Die angetriebene Motorspindel 3 überträgt die Antriebsbewegung über eine Kegelradumlenkung 4 auf eine Welle 5, auf der ein Zugseil 6 ausgebildet ist, das mit einem flaschenzugähnlichen Lineargetriebe 7 verbunden ist. Selbstverständlich kann jedes andere geeignete Getriebe verwandt werden. Innerhalb des Lineargetriebes 7 bestehen zwei Seilwalzen 8, 9, wobei die Seilwalze 9 mit einem beweglich ausgebildeten Schlitten 10 verbunden ist, der über Federn 11, 12 stets von der Seite des Antriebes weggedrückt wird, um stets eine gute Spannung des Zugseiles 6 innerhalb des Lineargetriebes 7 zu erreichen. An der antriebsentfernten Seite des Schlittens 10 befindet sich eine Platte 14, die mit einer Zugstange 15 verbunden ist, über die ein Pleuel 16 in Richtung des Antriebes gezogen werden kann, wobei das Pleuel 16 wiederum mit einem Kolben 17 verbunden ist. Dieser Kolben 17 weist eine Kraftübertragungsvorrichtung zu einem Hebel 18 auf, der mit der zu öffnenden Tür unmittelbar bzw. mittelbar verbunden ist, d. h. bei einer Hin- und Herbewegung des Kolbens 16 wird der Hebel 18 ebenfalls hin- und hergeschwenkt. Die Übertragung zwischen Kolben 17 und Hebel 18 erfolgt in diesem Ausführungsbeispiel über ein mit einer Verzahnung ausgebildetes Langloch in dem Kolben 17, wobei diese Langlochverzahnung mit einer ebenfalls eine Verzahnung aufweisenden Welle 19 kämmt, auf der wiederum der Hebel 18 ausgebildet ist. Zwischen dem Antrieb 2 und der in diesem Ausführungsbeispiel nicht dargestellten Tür befindet sich das Verbindungselement 20, das im wesentlichen aus der Zugstange 15 und dem Pleuel 16 besteht. Am antriebsseitigen Stirnende des Pleuels 16 befindet sich ein Splint 21, der das Pleuel 16 überragend ausgebildet ist. Der Splint 21 wird innerhalb eines Langloches 22 (das auch eine Nut sein kann) geführt, das in der Zugstange 15 ausgebildet ist. Dabei ermöglicht das Langloch 22 eine teleskopierende Bewegung des Pleuels 16 innerhalb der Zugstange 15, wobei die Seitenränder des Langloches 22 als Begrenzung für die Beweglichkeit des Pleuels 16 in der Zugstange 15 dienen.Referring to the figures, a door opener 1 consists of a only partially shown drive 2, in this embodiment is designed as an electric motor. The driven Motor spindle 3 transmits the drive movement via a Bevel gear deflection 4 on a shaft 5 on which a pull rope 6 is formed with a pulley-like linear gear 7 is connected. Of course, everyone else can suitable gears are used. Inside the linear gear 7 there are two rope rollers 8, 9, the rope roller 9 is connected to a moveable slide 10, which is always pushed away from the side of the drive via springs 11, 12 is always a good tension of the pull rope 6 within to achieve the linear gear 7. At the drive remote Side of the carriage 10 is a plate 14 which is connected to a tie rod 15 via which a connecting rod 16 in Direction of the drive can be pulled, the connecting rod 16 is in turn connected to a piston 17. That piston 17 has a power transmission device for a lever 18 on, which is directly or indirectly connected to the door to be opened is, d. H. when the piston reciprocates 16, the lever 18 is also pivoted back and forth. The Transmission between piston 17 and lever 18 takes place in this Embodiment of a formed with a toothing Elongated hole in the piston 17, this elongated hole toothing with a shaft that also has a toothing 19 combs, on which in turn the lever 18 is formed. Between the drive 2 and that in this embodiment door, not shown, is the connecting element 20, which consists essentially of the tie rod 15 and the connecting rod 16 exists. Located on the drive end of the connecting rod 16 a cotter pin 21, which conrods the connecting rod 16 is. The split pin 21 is within an elongated hole 22 (that too can be a groove) which is formed in the pull rod 15 is. The elongated hole 22 enables a telescopic Movement of the connecting rod 16 within the tie rod 15, wherein the side edges of the elongated hole 22 as a limitation for mobility the connecting rod 16 in the tie rod 15.

In der in den Figuren dargestellten Ausbildung befindet sich der Splint an dem antriebsentfernten Rand des Langloches 22, und bei einem Betätigen des Antriebes 2 erfolgt über die Motorspindel 3 eine Drehung der Welle 5 und dementsprechend eine Straffung des Zugseiles 6, die dazu führt, daß der Schlitten 10 mitsamt der Platte 14 entsprechend der gewählten Getriebe- über- oder -untersetzung in Richtung des Antriebes 2 gezogen wird. Dies führt ebenfalls zu einem Heranziehen der mit der Platte 14 verbundenen Zugstange 15 in Richtung des Antriebes 2, und da der Splint 21 an der Stirnseite 23 der Zugstange 15 anliegt, wird das Pleuel 16 mitsamt des daran befestigten Kolben 17 ebenfalls in Richtung des Antriebes 2 gezogen und führt zu einer Öffnungsbewegung des Hebels 18 und somit zu einem Öffnen der damit verbundenen Tür. Dabei erfolgt die Bewegung des Kolbens 17 gegen die Kraft einer Türschließfeder 24. Hat die Tür ihre Öffnungsposition erreicht, erfolgt ein Abschalten des Antriebes 2, und aufgrund der Federwirkung der Türschließfeder 14 wird der Kolben 17 wieder in die antriebsentfernte Position zurückgedrückt und hierdurch wird die Türschließung über den Hebel 18 bewirkt.In the training shown in the figures is the Split pin on the edge of the elongated hole 22, and when the drive 2 is actuated via the motor spindle 3 a rotation of the shaft 5 and accordingly one Tightening the pull rope 6, which leads to the carriage 10 together with the plate 14 according to the selected gear step up or step down in the direction of the drive 2 becomes. This also leads to pulling up with the plate 14 connected pull rod 15 in the direction of the drive 2, and since the split pin 21 rests on the end face 23 of the pull rod 15, the connecting rod 16 together with the piston attached to it 17 also pulled in the direction of the drive 2 and leads to an opening movement of the lever 18 and thus to one Open the associated door. The movement takes place of the piston 17 against the force of a door closing spring 24. Has the door reaches its opening position, the Drive 2, and due to the spring action of the door closing spring 14, the piston 17 is again in the position removed from the drive pushed back and this causes the door to close causes the lever 18.

Sollte die Tür einmal manuell geöffnet werden, z. B. wenn im Brandfall der Strom ausfällt oder aber eine Person möchte die Tür aus diversen Gründen lediglich manuell öffnen, erfolgt beim Aufdrücken der Tür ein umgekehrter Kraftfluß wie der oben beschriebene. Durch das Aufdrücken der Tür erfolgt über den Hebel 18 eine Bewegung des damit verbundenen Kolbens 17 in Richtung des Antriebes 2, entgegen der Kraft der Türschließfeder 24, und bei diesem Kraftfluß von der zu öffnenden Tür in Richtung des Antriebes 2 kann sich nun das Pleuel 16 (türseitiger Verbindungskörper) relativ zu der Zugstange 15 (antriebsseitiger Verbindungskörper) bewegen, da in dieser Kraftflußrichtung der Splint 21 sich innerhalb des Langloches 22 bewegen kann.Should the door be opened manually, e.g. B. if in In the event of a fire, the power fails or a person wants the Only open the door manually for various reasons Pushing the door open a reverse flow of force like that described above. The door is pushed open using the lever 18 a movement of the piston 17 connected thereto Direction of drive 2, against the force of the door closing spring 24, and with this flow of force from the door to be opened in The connecting rod 16 (on the door side Connection body) relative to the tie rod 15 (drive side Connecting body) because in this direction of force flow the cotter pin 21 move within the elongated hole 22 can.

Mit anderen Worten ausgedrückt wird bei einem Kraftfluß von der Tür in Richtung des Antriebes lediglich der Hebel 18 bewegt sowie der Kolben 17 mit der daran befindlichen Pleuelstange 16 sowie die Türschließfeder 24, jedoch erfolgt eine Entkoppelung des gesamten Getriebes wie auch des Antriebes 2, so daß durch diese Entkoppelung eine weitaus geringere Öffnungskraft auf die Tür aufzubringen ist, als wenn bei einem manuellen Öffnen der Tür auch das Getriebe und der Antriebsmotor bewegt werden müssen. Hierdurch kann z. B. im Brandfall eine mit einem öffnungsgemäßen Türöffner versehene Tür auch von behinderten Personen noch geöffnet werden.In other words, with a power flow of only the lever 18 moves the door in the direction of the drive and the piston 17 with the connecting rod 16 thereon and the door closing spring 24, but decoupling takes place of the entire transmission as well as the drive 2, so that due to this decoupling a much lower opening force is to be applied to the door as if it were opened manually the door also moves the gear and the drive motor Need to become. As a result, z. B. in the event of a fire with one Door with opening according to opening, also by disabled people People can still be opened.

Selbstverständlich können andere Kupplungsarten als die dargestellte verwandt werdne, um eine Entkoppelung des Antriebes bzw. des damit verbundenen Getriebes von dem manuellen Türöffnen zu erreichen, und die Erfindung ist nicht auf das konkrete dargestellte Ausführungsbeispiel eingeschränkt, wobei es sich bei dem dargestellten Ausführungsbeispiel um eine besonders robuste und einfach zu konstruierende sowie kostengünstige Möglichkeit der Entkoppelung des Antriebes von dem Türöffnungsmechanismus zu erhalten.Of course, other types of coupling than the one shown be used to decouple the drive or the associated transmission from the manual To achieve door opening, and the invention is not specific illustrated embodiment limited, it is a special in the illustrated embodiment robust and easy to construct as well as inexpensive Possibility of decoupling the drive from the door opening mechanism to obtain.

In vorteilhafter Ausgestaltung kann sowohl das Getriebe als auch das Verbindungselement in ein und demselben Gehäuse angeordnet werden, um eine besonders platzsparende Ausgestaltung zu erreichen.In an advantageous embodiment, both the transmission and also the connecting element in one and the same housing can be arranged to a particularly space-saving design to reach.

Selbstverständlich kann in einer anderen Ausführungsart der antriebsseitige Verbindungskörper innerhalb eines türseitigen Verbindungskörpers verlaufend ausgebildet sein. Anstatt der vorgeschlagenen teleskopierbaren Stangen können z. B. Kupplungen oder klauenartige Verbindungskörper gewählt werden, die den gleichen Zweck wie die vorgeschlagene Verbindungsart ermöglichen, nämlich die Entkoppelung des Antriebes bzw. eines evtl. vorhandenen Getriebes von der Öffnungsbewegung einer manuell geöffneten Tür bzw. des hiervon ausgehenden Kraftflusses von der Tür in Richtung des Antriebes.Of course, in another embodiment, the drive-side connecting body within a door-side Connection body be designed to extend. Instead of proposed telescopic rods can e.g. B. Couplings or claw-like connecting bodies are selected, which has the same purpose as the proposed connection type enable, namely the decoupling of the drive or a possibly existing gear from the opening movement a manually opened door or the one starting from it Power flow from the door towards the drive.
