Description
Die vorliegende Erfindung betrifft eine Druckstange zur Betätigung eines Türverschlusses einer Tür, mit einem zur Befestigung an der Tür dienenden Grundprofil und mit einem relativ zum Grundprofil verlagerbaren und als Betätigungselement für den Türverschluss dienenden Deckprofil, das zwischen einer unbetätigten Anfangslage und einer vollständig betätigten Endlage verlagerbar ist.The present invention relates to a push rod for actuating a door lock of a door, with a base profile serving for fastening to the door and with a cover profile which can be displaced relative to the base profile and serves as an actuating element for the door lock and which can be shifted between an unactuated initial position and a fully actuated end position ,
Druckstangen zur Betätigung und Entriegelung von Fluchttüren sind aus dem Stand der Technik bekannt. Aus der
Bei den voranstehend beschriebenen Vorrichtungen besteht Raum für Optimierungen, da diese zur Feststellung des Türverschlusses einen komplexen Aufbau mit einem ggf. hohen Platzbedarf insbesondere innerhalb der Druckstange aufweisen. Zudem sind diese Vorrichtungen in der Herstellung aufwändig.
Die vorliegende Erfindung löst die voranstehende Aufgabe mit den Merkmalen des Anspruchs 1. Erfindungsgemäß ist es vorgesehen, dass das Deckprofil und das Grundprofil mittels eines ein Kniegelenk aufweisenden Kniehebels gekoppelt sind und dass das Deckprofil in oder nahe seiner Anfangslage mittels eines auf das Kniegelenk wirkenden Elektromagneten feststellbar ist.The present invention achieves the above object with the features of claim 1. According to the invention, it is provided that the cover profile and the base profile are coupled by means of a knee lever having a knee joint and that the cover profile can be determined in or near its initial position by means of an electromagnet acting on the knee joint is.
Eine derartige Ausgestaltung hat den Vorteil, dass mittels des Kniegelenks eine konstruktiv einfache und stabile Kopplung des Grundprofils und des Deckprofils aneinander geschaffen sind. Zudem ist ein solches Kniegelenk einfach und kostengünstig herzustellen. Im Vergleich zu einer Linearführung lässt sich durch Verwendung eines Kniegelenks innerhalb der Druckstange ein vergleichsweise geringer Platzbedarf erreichen. Durch gezieltes Wirken des Elektromagneten auf das Kniegelenk, nämlich einem Feststellen oder Sperren des Kniegelenks, kann auch bei geringer Haltekraft des Elektromagneten einer hohen Druckkraft auf das Deckprofil, insbesondere einer Druckkraft oberhalb von 3000 Newton, standgehalten werden. Der Türverschluss kann insbesondere als Türfalle ausgebildet sein. Demnach kann die Druckstange zur Betätigung einer Türfalle einer Tür dienen.Such an embodiment has the advantage that a structurally simple and stable coupling of the base profile and the cover profile to one another is created by means of the knee joint. In addition, such a knee joint is simple and inexpensive to manufacture. Compared to a linear guide, a comparatively small space requirement can be achieved by using a knee joint within the push rod. By targeted action of the electromagnet on the knee joint, namely locking or locking the knee joint, a high compressive force on the cover profile, in particular a compressive force above 3000 Newtons, can be withstood even with a low holding force of the electromagnet. The door lock can in particular be designed as a door latch. Accordingly, the push rod can be used to actuate a door latch of a door.
Das Deckprofil kann vorzugsweise parallel zum Grundprofil verlagerbar sein.The cover profile can preferably be displaceable parallel to the basic profile.
Der Ausdruck "nahe an seiner Anfangslage" ist dahingehend zu verstehen, dass diese Position bezogen auf den gesamten Verlagerungsweg des Deckprofils (Abstand Anfangslage zu Endlage) weniger als 20 Prozent, vorzugsweise weniger als 15 Prozent, weiter vorzugsweise weniger als zehn Prozent, weiter vorzugsweise weniger als fünf Prozent, von der Anfangslage entfernt ist.The expression “close to its initial position” is to be understood to mean that this position is less than 20 percent, preferably less than 15 percent, more preferably less than ten percent, more preferably less, based on the total displacement path of the cover profile (distance from initial position to end position) than five percent from the initial position.
Der Kniehebel besteht im Konkreten aus zwei durch ein Gelenk, das Kniegelenk, miteinander verbundenen einarmigen Hebeln, die an ihren vom Kniegelenk abgewandten Enden jeweils beweglich an einem Gelenk gelagert sind. Der erste einarmige Hebel ist gelenkig an einem deckprofilseitigen Gelenk gelagert. Der zweite einarmige Hebel ist gelenkig an einem grundprofilseitigen Gelenk gelagert.Specifically, the toggle lever consists of two one-armed levers connected to one another by a joint, the knee joint, which are each movably mounted on a joint at their ends facing away from the knee joint. The first one-armed lever is articulated on a joint on the cover profile side. The second one-armed lever is articulated on a joint on the basic profile side.
In vorteilhafter Weise kann der Elektromagnet mit dem Grundprofil verbunden sein. Hiermit ist eine konstruktiv einfache Anordnung des Elektromagneten innerhalb der Druckstange erreicht, da der Elektromagnet ortsfest - mittelbar oder unmittelbar - am Grundprofil befestigt ist. Dies erleichtert den Anschluss des Elektromagneten, der beispielsweise über das Grundprofil oder eine dort vorgesehene Durchführung mittels einer entsprechenden Verkabelung mit Energie versorgt werden kann. Aufgrund der ortsfesten Anordnung des Elektromagneten wird die Verkabelung nicht auf Zug oder Druck belastet, was zu einer hohen Einsatzdauer beiträgt.The electromagnet can advantageously be connected to the basic profile. This achieves a structurally simple arrangement of the electromagnet within the push rod, since the electromagnet is fixed in place - indirectly or directly - to the basic profile. This simplifies the connection of the electromagnet, which can be supplied with energy, for example, via the basic profile or a bushing provided there by means of appropriate cabling. Due to the fixed arrangement of the electromagnet, the wiring is not subjected to tension or pressure, which contributes to a long service life.
Weiter erfindungsgemäß wirkt der Elektromagnet mittels eines schwenkbar am Kniegelenk gelagerten Verbindungselements auf das Kniegelenk. Dies hat den Vorteil, dass der Elektromagnet außerhalb des Schwenkbereichs des Kniegelenks angeordnet werden kann, so dass die Konstruktion des Kniegelenks und deren Schwenkbewegung durch den Elektromagneten nicht beeinträchtigt ist. Beispielsweise lassen sich so auch Elektromagneten mit vergleichsweise großer Stirnfläche einsetzen. Im Konkreten kann das Verbindungselement als Verbindungsstange ausgeführt sein, beispielsweise in Form eines sich geradlinig erstreckenden Kreiszylinders.According to the invention, the electromagnet acts by means of a pivotally mounted on the knee joint Fastener on the knee joint. This has the advantage that the electromagnet can be arranged outside the swivel range of the knee joint, so that the construction of the knee joint and its swiveling movement are not impaired by the electromagnet. For example, electromagnets with a comparatively large end face can also be used in this way. In concrete terms, the connecting element can be designed as a connecting rod, for example in the form of a rectilinearly extending circular cylinder.
In vorteilhafter Weise kann der Elektromagnet mit einer mit dem Kniegelenk gekoppelten Haftplatte zusammenwirken. Die Haftplatte kann insbesondere am Verbindungselement befestigt sein. Durch Zusammenwirken von Haftplatte und Elektromagnet ist im aktivierten Zustand des Elektromagneten eine zuverlässige Fixierung des Kniegelenks durch den Elektromagneten erreicht. Durch Verwendung einer Haftplatte kann bei einem Elektromagneten mit vergleichswese großer Stirnfläche diese vollständig genutzt werden. Dabei kann die Dimensionierung des Verbindungselements und der Haftplatte unabhängig voneinander erfolgen. Dies begünstigt die Konstruktion des Kniehebels, da das Verbindungselement in seinem Querschnitt kleiner dimensioniert werden kann als der Querschnitt der Haftplatte.The electromagnet can advantageously cooperate with an adhesive plate coupled to the knee joint. The adhesive plate can in particular be attached to the connecting element. Through the interaction of the adhesive plate and the electromagnet, a reliable fixation of the knee joint by the electromagnet is achieved in the activated state of the electromagnet. By using an adhesive plate, an electromagnet with a comparably large end face can be fully used. The dimensioning of the connecting element and the adhesive plate can take place independently of one another. This favors the construction of the toggle lever, since the cross section of the connecting element can be made smaller than the cross section of the adhesive plate.
Weiter erfindungsgemäß ist das Verbindungselement an seinem vom Kniegelenk abgewandten Ende an einer am Grundprofil befestigten Führungseinrichtung mittels einer Führungsbahn geführt. Die Führungsbahn ist bogenförmig ausgebildet, beispielsweise in Form eines Kreisbogenabschnitts. Durch die Führungseinrichtung wird der Verlagerungsvorgang des Deckprofils relativ zum Grundprofil stabilisiert, so dass das Deckprofil weitestgehend parallel zum Grundprofil verschwenkt werden kann. Zudem ist durch die Führungseinrichtung die Verlagerung des Deckprofils relativ zum Grundprofil begrenzt, und zwar unabhängig von etwaigen Anschlägen zwischen Deckprofil und Grundprofil.According to the invention, the connecting element is guided at its end facing away from the knee joint on a guide device fastened to the base profile by means of a guide track. The guideway is arcuate, for example in the form of a circular arc section. The displacement process of the cover profile is stabilized relative to the base profile by the guide device, so that the cover profile can be pivoted largely parallel to the basic profile. In addition, the displacement of the cover profile relative to the base profile is limited by the guide device, regardless of any stops between the cover profile and the base profile.
Im Konkreten kann die Führungseinrichtung Wandabschnitte mit insbesondere bogenförmigen Ausnehmungen aufweisen, wobei die Ausnehmungen die Führungsbahn bilden. Die Ausnehmungen können als Vertiefungen oder Durchgänge ausgebildet sein. Hiermit ist mit einfachen konstruktiven Mitteln eine stabile Führungsbahn geschaffen.Specifically, the guide device can have wall sections with, in particular, arcuate recesses, the recesses forming the guide track. The recesses can be designed as depressions or passages. This creates a stable guideway with simple constructional means.
Zweckmäßigerweise kann das Verbindungselement an seinem vom Kniegelenk abgewandten Ende ein Eingriffselement oder einen Bolzen aufweisen, das/der in die Ausnehmungen eingreift und an oder in den Ausnehmungen geführt ist. Hiermit ist mit konstruktiv einfachen Mitteln eine Kopplung zwischen den Führungsbahnen und dem Verbindungselement erreicht. Das Eingriffselement oder der Bolzen ist insbesondere derart ausgerichtet, dass dessen Längsrichtung orthogonal zur Längsrichtung des Verbindungselements orientiert ist.The connecting element can expediently have an engagement element or a bolt at its end facing away from the knee joint, which engages in the recesses and is guided on or in the recesses. A coupling between the guideways and the connecting element is hereby achieved with structurally simple means. The engagement element or the bolt is in particular aligned in such a way that its longitudinal direction is oriented orthogonally to the longitudinal direction of the connecting element.
Für eine möglichst stabile Anbindung des Elektromagneten am Grundprofil ist es von Vorteil, wenn der Elektromagnet an einem die Wandabschnitte verbindenden Schenkel befestigt ist. Dies führt zu einer konstruktiv stabilen und zugleich kompakten Ausgestaltung der Führungseinrichtung. Die Wandabschnitte und der die Wandabschnitte verbindende Schenkel können in Draufsicht einen U-förmigen Querschnitt aufweisen, wobei im Zwischenraum des "U" der Elektromagnet befestigt ist.For the most stable possible connection of the electromagnet to the base profile, it is advantageous if the electromagnet is attached to a leg connecting the wall sections. This leads to a structurally stable and at the same time compact design of the guide device. The wall sections and the leg connecting the wall sections can have a U-shaped cross section in plan view, the electromagnet being fastened in the space between the "U".
In vorteilhafter Weise ist der Kniehebel mittels plattenartigen Befestigungsabschnitten am Deckprofil und/oder am Grundprofil befestigt. Dies stabilisiert eine Verlagerung des Deckprofils relativ zum Grundprofil zusätzlich, da Lasten nicht nur punktuell oder linienförmig, sondern flächig aufgenommen und auf Grundprofil oder Deckprofil übertragen werden können. Dabei sind der erste einarmige Hebel und der zweite einarmige Hebel, die den Kniehebel bilden, mittels Lagerpunkten schwenkbar an den plattenartigen Befestigungsabschnitten gelagert.The toggle lever is advantageously fastened to the cover profile and / or to the base profile by means of plate-like fastening sections. This also stabilizes a shift of the cover profile relative to the base profile, since loads can not only be picked up punctually or linearly, but also over a large area and transferred to the base profile or cover profile. The first one-armed lever and the second one-armed lever, which form the toggle lever, are pivotally mounted on the plate-like fastening sections by means of bearing points.
In vorteilhafter Weise bilden der Kniehebel, die Führungseinrichtung und der Elektromagnet ein Sperrmodul. Mit anderen Worten bilden diese Komponenten eine modulare Baueinheit, die als solche gehandhabt und in eine Druckstange eingebaut werden kann. Beispielsweise ist hiermit auch eine Nachrüstung einer Druckstange möglich.The toggle lever, the guide device and the electromagnet advantageously form a locking module. In other words, these components form a modular unit that can be handled as such and installed in a push rod. For example, this can also be used to retrofit a push rod.
Zweckmäßigerweise schließen der erste einarmige Hebel und der zweite einarmige Hebel, die den Kniehebel bilden, in der unbetätigten Anfangslage des Deckprofils relativ zueinander an der dem Elektromagneten zugewandten Seite einen Winkel von 175° bis 180°, vorzugsweise 176° bis 179°, weiter vorzugsweise 177° bis 178°, ein. Durch diese Anordnung ist die Richtung der Schwenkbewegung bei einem Aufbringen einer Kraft auf das Deckprofil vorgegeben. Zudem ist bei einer Feststellung des Kniehebels die durch den Elektromagneten aufzubringende Kraft zum Widerstand gegen eine auf das Deckprofil aufgebrachte Druckkraft von 3000 N relativ gering und beträgt etwa 240 N.The first one-armed lever and the second one-armed lever, which form the toggle lever, expediently close an angle of 175 ° to 180 °, preferably 176 ° to 179 °, more preferably 177, in the unactuated initial position of the cover profile on the side facing the electromagnet ° to 178 °, a. This arrangement specifies the direction of the pivoting movement when a force is applied to the cover profile. In addition, when the toggle lever is locked, the force to be exerted by the electromagnet to resist a pressure force of 3000 N applied to the cover profile is relatively low and is approximately 240 N.
In vorteilhafter Weise ist der Elektromagnet federnd am Grundprofil befestigt. Insbesondere kann der Elektromagnet federnd am Schenkel der Führungseinrichtung befestigt sein. Hiermit ist ein zuverlässiges Feststellen des Deckprofils gewährleistet, da eine spielfreie Anlage des Elektromagneten am Verbindungselement oder der Anlageplatte gewährleistet ist.The electromagnet is advantageously resiliently attached to the base profile. In particular, the electromagnet be resiliently attached to the leg of the guide device. This ensures a reliable fixing of the cover profile, since a play-free contact of the electromagnet on the connecting element or the contact plate is guaranteed.
Alternativ oder ergänzend kann die Haftplatte federnd am Verbindungselement befestigt sein. Auch dies unterstützt eine zuverlässige Feststellung des Deckprofils, da auch hiermit eine spielfreie Anlage am Elektromagneten sichergestellt ist.Alternatively or in addition, the adhesive plate can be resiliently attached to the connecting element. This also supports a reliable determination of the cover profile, since this also ensures play-free contact with the electromagnet.
Zweckmäßigerweise ist der Elektromagnet in einem Normalzustand bestromt und stellt im bestromten Zustand das Deckprofil in oder nahe an seiner Anfangslage fest.The electromagnet is expediently energized in a normal state and, when energized, detects the cover profile in or close to its initial position.
