Die Erfindung betrifft einen Türöffner nach dem Oberbegriff des Anspruches 1. Ein solcher Türöffner weist eine in einem Türöffnergehäuse ausgebildete Türöffnerfalle sowie eine Verschiebeeinrichtung mit einem Kontaktbereich auf, der zum kraftschlüssigen Eingriff mit einer in die Türöffnerfalle aufnehmbaren Schlossfalle ausgebildet ist. Die Verschiebeeinrichtung ist dabei zur geradlinigen Längsverschiebung der Schlossfalle ausgebildet.The invention relates to a door opener according to the preamble of claim 1. Such a door opener has a door opener trap formed in a door opener housing and a displacement device with a contact area for frictional engagement with a recordable in the door latch Lock latch is formed. The displacement device is for straight-line longitudinal displacement the latch formed.

Derartige Türöffner werden beispielsweise bei komplexen Schließanlagen eingesetzt, bei welchen Türen ferngesteuert ver- oder entriegelt werden müssen. Häufig sind dabei aus versicherungstechnischen Gründen oder zur Einhaltung der Vorschriften der Wärmeschutzverordnung zusätzliche Verriegelungseinheiten mit entsprechenden Türöffnereinheiten erforderlich. Typischerweise greifen bei diesen Türöffnern die Schlossfallen in Verriegelungsstellung 20 mm tief in die Türöffner ein.Such door openers are used for example in complex locking systems, in which Doors must be remotely locked or unlocked. Often, these are underwriting Reasons or to comply with the provisions of the Heat Insulation Regulation additional locking units required with appropriate door opener units. Typically, they help These door openers, the lock traps in locking position 20 mm deep in the door opener.

Ein gattungsgemäßer Türöffner ist beispielsweise aus der EP 0853176 A1 bekannt. Bei der dort beschriebenen Schließeinrichtung kann eine Schlossfalle eines Schlosses aus einer Verriegelungsstellung, bei der die Schlossfalle in einer Öffnerfalle des Türöffnergehäuses aufgenommen ist, mit Hilfe eines Schiebers in eine Entriegelungsstellung zurückgeschoben werden, in welcher die Schlossfalle in einem Schlossgehäuse aufgenommen ist. Die in der EP 0853176 A1 offenbarte Schließeinrichtung erlaubt in äußerst zuverlässiger Weise ein Offen- bzw. Geschlossenstellen einer zu verriegelnden Tür.A generic door opener is known for example from EP 0853176 A1. At the described there Locking device can lock a lock of a lock from a locking position, in which the latch is received in a Öffnerfalle the door opener housing, with the help of a Slider be pushed back into an unlocked position in which the latch in a Lock housing is added. The locking device disclosed in EP 0853176 A1 allows in extremely reliable way an open or closed positions of a door to be locked.

Da die Schlossfalle bei der EP 0853176 A1 in der Entriegelungsstellung praktisch vollständig im Schlossgehäuse aufgenommen wird, ist die Tür nicht mehr gefangen und kann bei entsprechender Aufhängung bereits durch geringen Kraftaufwand aufgedrückt werden. Dies ist häufig auch erwünscht. Since the latch in the EP 0853176 A1 in the unlocked position practically completely in Lock housing is added, the door is no longer trapped and can be at appropriate Suspension already be pressed by little effort. This is often desirable.

In der DE 19609846 A1 wird ein Türöffner mit einem Gleitblech für die Schlossfalle eines Türschlosses zur Verwendung bei einem elektrischen Türöffner beschrieben. Das Gleitblech weist eine Öffnung auf, durch welche die Schlossfalle für das Einrasten an der Türöffnerfalle hindurch greifen kann. In der Öffnung des Gleitblechs ist wenigstens ein Steg vorgesehen, der mit seinem freien Ende bis an die Türöffnerfalle reicht. Dieser Steg bildet eine schräg verlaufenden Gleitfläche, an der die Schlossfalle in der nicht verriegelnden Stellung beim Öffnen des Türflügels federnd zurück gedrückt werden kann.In DE 19609846 A1, a door opener with a sliding plate for the latch of a door lock for use with an electric strike. The sliding plate has an opening on, through which the latch latch can engage for latching on the door opener trap. In the opening of the sliding plate is provided at least one web, with its free end up to the Door opener trap is enough. This web forms an inclined sliding surface on which the latch in the non-locking position when opening the door leaf can be pushed back resiliently.

Es haben sich allerdings in der Praxis auch Anwendungsfälle ergeben, bei denen eine gewisse Fixierung der Tür in einem prinzipiell schon entriegelten Zustand erforderlich ist. Insbesondere ist es häufig wünschenswert, dass ein zufälliges Aufdrücken der Tür, etwa durch einen Windstoß, verhindert wird. Auch im Brandfall ist es nicht erwünscht, dass sich Türen unkontrolliert öffnen.However, there have also been applications in practice in which a certain fixation the door is required in a basically unlocked state. In particular, it is common desirable that accidental pressing of the door, such as by a gust, prevented becomes. Even in case of fire, it is not desirable that doors open uncontrollably.

Vor diesem Hintergrund des Standes der Technik ist es Aufgabe der vorliegenden Erfindung, einen Türöffner anzugeben, mit welchem in zuverlässiger Weise ein Geschlossen- und Offenstellen einer Tür möglich ist und welcher darüber hinaus ein zufälliges Öffnen der Tür im entriegelten Zustand verhindert. Der Türöffner soll außerdem konstruktiv einfach aufgebaut sein.Against this background of the prior art, it is an object of the present invention to provide a door opener, with which in a reliable manner a closed and open a door is possible and which also prevents accidental opening of the door in the unlocked state. The door opener should also be structurally simple.

Diese Aufgabe wird erfindungsgemäß durch einen Türöffner mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beansprucht.This object is achieved by a door opener with the features of claim 1 solved. Advantageous developments of the invention are claimed in the subclaims.

Ein gattungsgemäßer Türöffner ist nach der Erfindung dadurch weitergebildet, dass die Verschiebeeinrichtung längs einer Schieberichtung mindestens zwischen einer Verriegelungsstellung und einer Zwischenstellung verschiebbar ist, dass mindestens ein Fallenführungsblech vorgesehen ist, welches eine sich quer zur Schieberichtung nach außen öffnende Führungsfläche aufweist, und dass in der Zwischenstellung der Verschiebeeinrichtung der Kontaktbereich im Bereich eines Ansatzes der Führungsfläche liegt.A generic door opener is further developed according to the invention in that the displacement device along a sliding direction at least between a locking position and a Sliding intermediate position is that at least one trap guide plate is provided, which has a transverse to the sliding direction outwardly opening guide surface, and that in the Intermediate position of the displacement device of the contact area in the region of a shoulder of the guide surface lies.

Unter der Schieberichtung soll hier die Richtung der geradlinigen Längsverschiebung der Schlossfalle verstanden werden. Diese Richtung verläuft üblicherweise senkrecht zu einer Öffnungsrichtung der Türe, wobei eine Schlossfalle stirnseitig aus dem Türöffnergehäuse heraus und in ein in einem Türrahmen angeordnetes Schlossgehäuse hineingedrückt wird.Under the sliding direction here is the direction of the linear longitudinal displacement of the latch be understood. This direction is usually perpendicular to an opening direction of the Door, wherein a latch bolt frontally out of the door opener housing and in a door frame arranged lock housing is pressed.

Als Kerngedanke der vorliegenden Erfindung kann angesehen werden, dass im Gegensatz zum Stand der Technik nicht mehr vorgesehen ist, eine Schlossfalle mit Hilfe einer Verschiebeeinrichtung aus einer Verriegelungsstellung vollständig aus dem Türöffnergehäuse herauszudrücken. Vielmehr wird bei der vorliegenden Erfindung eine Schlossfalle lediglich bis zu einer zwischen der Verriegelungs- und Entriegelungstellung liegenden Zwischenstellung herausgedrückt. Einmal in die Zwischenstellung gebracht, liegt eine Schlossfalle, welche üblicherweise von einer Feder nach außen gedrückt wird, kraftschlüssig an dem erfindungsgemäß vorgesehenen Fallenführungsblech an. Die Schlossfalle befindet sich dann gewissermaßen in einer Vorentriegelungsstellung, in der die Verriegelung zwar aufgehoben ist, die Tür aber noch nicht vollständig frei ist. In dieser Vorentriegelungsstelllung ist also eine Zuhaltefunktion des Türöffners weiterhin gegeben. Durch einen entsprechenden Druck in Öffnungsrichtung der Türe entsteht aufgrund der sich nach außen öffnenden Führungsfläche des Fallenführungsbleches eine resultierende Kraft, welche die Schlossfalle weiter in das Schlossgehäuse hineindrückt. Dies setzt sich so lange fort, bis die Schlossfalle vollständig im Schlossgehäuse aufgenommen und damit die volle Entriegelungstellung erreicht ist.As a core idea of the present invention can be considered that in contrast to the prior the technology is no longer provided a lock latch using a displacement device a locking position completely push out of the door opener housing. Rather, it will in the present invention a latch only up to one between the locking and unlocking position lying intermediate position pushed out. Once in the intermediate position brought, is a latch, which is usually pushed by a spring to the outside, non-positively on the inventively provided trap guide plate. The latch is located then, so to speak, in a Vorentriegelungsstellung in which the lock while repealed is, but the door is not completely free yet. In this Vorentriegelungsstelllung is therefore a Locking function of the door opener continues to be given. By a corresponding pressure in the opening direction the door is created due to the outwardly opening guide surface of the trap guide plate a resultant force which pushes the latch further into the lock housing. This continues until the latch completely accommodated in the lock housing and thus the full unlocked position is reached.

Mit dem erfindungsgemäßen Türöffner kann in konstruktiv besonders einfacher, dabei aber sehr robuster Weise eine Fixierung der prinzipiell schon entriegelten Türe erreicht werden und ein zufälliges Öffnen der Türe, beispielsweise durch einen Windstoß, verhindert werden.With the door opener according to the invention can be structurally particularly simple, but very robust A fixation of the principle already unlocked door can be achieved and a random Opening the door, for example, by a gust of wind to be prevented.

In der Praxis hat sich als vorteilhaft erwiesen, die Schlossfalle bis zu einer Tiefe von etwa 5 mm in Eingriff mit der Türöffnerfalle zu belassen.In practice, it has proven to be advantageous, the latch bolt to a depth of about 5 mm in To leave intervention with the door opener trap.

In einer besonders bevorzugten Ausführungsform der Erfindung ist die Führungsfläche als ebene Fläche ausgebildet. Dies ist einerseits konstruktiv leicht realisierbar und ermöglicht darüber hinaus bei linearer Kraftkennlinie der Federeinrichtung der Schlossfalle einen linearen Anstieg der zur Öffnung der Tür erforderlichen Kraft.In a particularly preferred embodiment of the invention, the guide surface is planar Surface trained. On the one hand, this is structurally easy to implement and also allows for linear force characteristic of the spring means of the latch a linear increase of the opening the force required by the door.

Für Anwendungsfälle, in denen eine nichtlineare Kraftkennlinie erwünscht ist, können aber auch nichtebene Führungsflächen gewählt werden.For applications in which a non-linear force characteristic is desired, but can also non-planar guide surfaces are selected.

In einer besonders einfachen Ausgestaltung des erfindungsgemäßen Türöffners verläuft die Führungsfläche des Führungsbleches etwa in einem Winkel von 45 ° relativ zur Schieberichtung.In a particularly simple embodiment of the door opener according to the invention runs the Guide surface of the guide plate approximately at an angle of 45 ° relative to the sliding direction.

In einer herstellungstechnisch bevorzugten Variante des Türöffners ist das mindestens eine Fallenführungsblech einstückig mit einem Teil des Türöffnergehäuses ausgebildet. Es kann aber auch bevorzugt sein, dass das mindestens eine Fallenführungsblech als ein in das Türöffnergehäuse einzusetzendes Einzelteil ausgebildet ist. Dies kann sich insbesondere dann anbieten, wenn ein Grundtyp oder ein Grundmodul eines Türöffners an unterschiedliche Bedingungen angepasst werden soll.
Für Türen, die in zwei entgegengesetzte Richtungen zu öffnen sind, kann außerdem vorteilhaft sein, dass zwei einander gegenüberliegende Fallenführungsbleche mit jeweils einer Führungsfläche vorgesehen sind und dass sich die Führungsflächen quer zur Schieberichtung in entgegengesetzte Richtungen nach außen öffnen. Dadurch wird in beiden Öffnungsrichtungen der Türe eine Fixierung und damit eine Sicherung der Tür im vorentriegelten Zustand gewährleistet.In a manufacturing technology preferred variant of the door opener, the at least one trap guide plate is formed integrally with a part of the door opener housing. However, it may also be preferred that the at least one trap guide plate is formed as an item to be inserted into the door opener housing. This can be especially useful if a basic type or basic module of a door opener is to be adapted to different conditions.
For doors that are to be opened in two opposite directions, it may also be advantageous to provide two opposing tray guide plates, each with a guide surface, and that the guide surfaces open outwardly in opposite directions transverse to the sliding direction. As a result, a fixation and thus securing the door in the pre-unlocked state is ensured in both opening directions of the door.

Eine weitere bevorzugte Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass die Verschiebeeinrichtung einen drehbaren Hebel aufweist, welcher über einen Spindelantrieb bewegbar ist. Gegenüber dem Stand der Technik gewinnt man hierdurch zahlreiche Vorteile. Zum Einen ist das Linearglied als drehbarer Hebel ausgebildet, d.h. dass kein Schieber mehr notwendig ist. Der Türöffner ist daher einfacher, robuster, funktionssicherer und außerdem kostengünstiger herzustellen. Weiterhin ist bei einem solchen Türöffner ein Arbeitsstrom-Ruhestrombetrieb in einem Produkt möglich, wobei im Ruhestrombetrieb ein nur sehr geringer Energiebedarf besteht, keine Brummgeräusche sowie eine nur äußerst minimale Erwärmung entsteht. Darüber hinaus ermöglicht der Türöffner ein äußerst geräuscharmes Öffnen der Tür und ist außerdem auch optisch ansprechend, da in den Türprofilen kein Ausschnitt erforderlich ist. Vorteilhaft ist im Übrigen, dass die statische Stabilität der Türöffner-Schloss-Anordnung unabhängig vom Türöffner ist, sondern vielmehr von der Stabilität des Türschließbleches bestimmt wird. Der hier beschriebene Türöffner ist für Türschlösser mit 20 mm Fallenausschluss geeignet. Für den Einsatz in einer Schließanlage ist üblicherweise eine Ansteuerelektronik vorgesehen, wobei vielfältige Überwachungsfunktionen und Einsatzmöglichkeiten, wie z.B. Bustechnik, RR-Betrieb, Türüberwachung usw., möglich sind. Es lässt sich hierbei auch bei großen Spannungsschwankungen eine hohe Funktionssicherheit erzielen.A further preferred embodiment of the invention is characterized in that the displacement device a rotatable lever which is movable via a spindle drive. Compared to the prior art, this gives you numerous advantages. For one thing is Linear member formed as a rotatable lever, i. that no slider is necessary anymore. The door opener is therefore easier, more robust, more reliable and also cheaper to produce. Furthermore, in such a door opener a working current quiescent current operation in a product possible, with only a very low energy requirement in quiescent current operation, none Humming noises and a very minimal heating occurs. In addition, allows the door opener a very quiet opening the door and is also visually appealing, because in the door profiles no cutout is required. It is advantageous, moreover, that the static Stability of the door opener-lock arrangement is independent of the door opener, but rather of the Stability of the door strike plate is determined. The door opener described here is for door locks with 20 mm trap exclusion suitable. For use in a locking system is usually a Control electronics provided, with a variety of monitoring functions and applications, such as. Bus technology, RR operation, door monitoring, etc. are possible. It can be synonymous with large voltage fluctuations achieve high reliability.

Neben dem drehbar gelagerten Hebel kann als Verschiebeeinrichtung auch ein auf einem Zahnrad angeordneter Hebel mit einem zugehörigen Antriebsgetriebe vorgesehen sein, wobei das Antriebsgetriebe eine Zahnstange enthalten kann oder auch aus lediglich einer Zahnstange bestehen kann. Weiterhin können auch ein gezahnter Schieber und/oder Spindeln Teile der Verschiebeeinrichtung sein.In addition to the rotatably mounted lever can also be a on a gear as a displacement device arranged lever may be provided with an associated drive gear, wherein the drive gear may contain a rack or consist of only one rack can. Furthermore, a toothed slider and / or spindles parts of the displacement device be.

Als Stellantrieb für die Verschiebeeinrichtung kann ein Elektromotor, ein Getriebemotor, ein Gleichstrom- und/oder Linearmotor vorgesehen sein. Alternative Antriebsmöglichkeiten sind durch Memory-Drähte, elektrochemische und ferroelektrische Aktoren sowie durch Pneumatik- und Hydraulikrylinder gegeben.As an actuator for the displacement device may be an electric motor, a gear motor, a DC and / or be provided linear motor. Alternative drive options are through Memory wires, electrochemical and ferroelectric actuators as well as pneumatic and hydraulic cylinders given.

Erfindungsgemäßes Kernelement des in den Figuren 1 und 2 dargestellten Türöffners 3 ist das Fallenführungsblech 12, welches eine sich nach außen öffnende Führungsfläche 13 aufweist. In der hier gezeigten Ausführungsform ist die Führungsfläche 13 eben ausgebildet und verläuft etwa in einem Winkel von 45 ° relativ zur Schieberichtung. Der erfindungsgemäße Türöffner 3 arbeitet wie folgt:Inventive core element of the door opener 3 shown in Figures 1 and 2 is the trap guide plate 12, which has an outwardly opening guide surface 13. In the here the embodiment shown, the guide surface 13 is formed flat and extends approximately in one Angle of 45 ° relative to the sliding direction. The door opener 3 according to the invention operates as follows:

Im Verriegelungszustand greift eine Schlossfalle bis über den Ansatz 14 des Fallenführungsbleches 12 hinaus in die Türöffnerfalle 7 des Türöffnergehäuses 17 ein. Die Schlossfalle wird dann durch den parallel zur Schieberichtung verlaufenden Teil 16 des Fallenführungsbleches gehalten und die Tür kann nicht geöffnet werden. Wenn die Türe geöffnet werden soll, wird der drehbare Hebel 19 über den Elektromotor 26 und die Spindel 21 gedreht, wobei der Kontaktbereich 9 die in der Türöffnerfalle 7 befindliche Schlossfalle berührt und in Schieberichtung nach außen drückt. Sobald nun der Rand der Schlossfalle oder der Kontaktbereich 9 des drehbaren Hebels den Ansatz 14 der Führungsfläche 13 erreicht hat, kann die Tür durch Aufwendung einer definierten Kraft in Öffnungsrichtung aufgedrückt werden.
