Description

Die Erfindung betrifft einen versenkbaren Verschluss für Türen von insbesondere dünnwandigen Schaltschränken mit einer auf die Vorderseite des Türblatts aufzusetzenden und zur versenkbaren Aufnahme eines Hebelgriffes eingerichteten Mulde, wobei der Hebelgriff in seiner in die Mulde eingeklappten Stellung über eine Schließvorrichtung festlegbar sowie um eine in der Mulde ausgebildete Schwenkachse in eine Betätigungsposition aus der Mulde herausklappbar und der in der zum Türblatt senkrechten Ebene ausgerichtete, durch eine sich an der Mulde abstützende Feder unterstützte Betätigungsweg des Hebelgriffes in die Drehung eines wenigstens eine Verriegelungsstange antreibenden außenverzahnten Ritzels umsetzbar ist.The invention relates to a retractable closure for doors of particular thin-walled cabinets with a aufzusetzenden on the front of the door panel and furnished for retractable receiving a lever handle trough, wherein the lever handle in its folded position in the trough secured by a locking device and trained in a trough Swivel axis in an operating position from the trough folded out and aligned in the plane perpendicular to the door leaf, supported by a supported on the trough spring actuating travel of the lever handle in the rotation of at least one locking rod driving externally toothed pinion can be implemented.

Ein versenkbarer Verschluss mit den vorgenannten gattungsgemäßen Merkmalen ist aus der DE 297 05 508 U1 bekannt. Soweit es bei diesem Verschluss schon möglich ist, auf ein beispielsweise bei dem aus der EP 0 261 266 B1 ebenfalls bekannten Verschluss eingesetztes Stangenschloss zum Antrieb der wenigstens einen Verriegelungsstange zu verzichten, ist bei dem aus der DE 297 05 508 U1 bekannten Verschluss im Hinblick auf einen Einsatz des Verschlusses in Schaltschränken mit besonders schmalen, zur Anordnung der Verriegelungsstangen heranzuziehenden Verkantungsräumen der Betätigungsweg des Hebelgriffes in einer zum Türblatt senkrechten Ebene eingerichtet, wobei das von dem Hebelgriff bei seiner Betätigung angetriebene Ritzel senkrecht zur Türblattebene angeordnet ist und unmittelbar in die in einer zugeordneten Verriegelungsstange angeordneten Ausnehmungen eingreift. Ein versenkbarer Verschluss, wobei das von dem Hebelgriff bei seiner Betätigung angetriebene Ritzel parallel zur Türblattebene angeordnet ist, ist aus der EP 1 900 891 A2 bekannt.A retractable closure with the aforementioned generic features is known from DE 297 05 508 U1 known. As far as it is already possible with this closure, for example, in the case of the EP 0 261 266 B1 also known closure inserted rod lock to drive the at least one locking rod to dispense, is in which from the DE 297 05 508 U1 known closure with respect to a use of the closure in cabinets with particularly narrow, for the arrangement of the locking rods zoomed in tilting spaces of the actuating travel of the lever handle in one to the door leaf set vertical plane, wherein the driven by the lever handle during its operation pinion is arranged perpendicular to the door leaf level and engages directly in the arranged in an associated locking rod recesses. A retractable closure, wherein the driven by the lever handle during its operation pinion is arranged parallel to the door leaf level, is from the EP 1 900 891 A2 known.

Mit dem bekannten Verschluss ist zunächst der Nachteil einer entsprechenden Bautiefe verbunden, weil die Mulde mit einem an ihr ausgebildeten Ansatz das Türblatt in einem zugeordneten Durchbruch durchgreift und in dem Ansatz die Schwenklagerung des Hebelgriffes sowie das Drehlager für das an den Hebelgriff angeschlossene Ritzel angeordnet sind. Die senkrecht zur Türblattebene ausgerichtete Stellung des Ritzels bedingt einen entsprechend großen Abstand der Verriegelungsstange zum Türblatt, was je nach dem bei einem Schaltschrank zur Verfügung stehenden Einbauraum unerwünscht sein kann. Ein weiterer Nachteil besteht darin, dass über das senkrecht zur Türblattebene stehende Ritzel nur eine Verriegelungsstange in nur einer Richtung angetrieben werden kann.With the known closure, the disadvantage of a corresponding depth is first connected because the trough engages with a trained approach to the door leaf in an associated breakthrough and in the approach, the pivot bearing of the lever handle and the pivot bearing for the connected to the lever pinion pinion are arranged. The aligned perpendicular to the door leaf position of the pinion causes a correspondingly large distance between the locking rod to the door leaf, which may be undesirable depending on the installation space available for a control cabinet. Another disadvantage is that only one locking rod can be driven in only one direction via the perpendicular to the door leaf level pinion.

Der Erfindung liegt daher die Aufgabe zugrunde, bei einem versenkbaren Verschluss mit den eingangs genannten gattungsgemäßen Merkmalen die erforderliche Einbautiefe zu verringern.The invention is therefore based on the object with a retractable closure with the aforementioned generic features to reduce the required installation depth.

Die Lösung dieser Aufgabe ergibt sich einschließlich vorteilhafter Ausgestaltungen und Weiterbildungen der Erfindung aus dem Inhalt der Patentansprüche, welche dieser Beschreibung nachgestellt sind.The solution to this problem arises, including advantageous refinements and developments of the invention from the content of the claims, which are adjusted to this description.

Die Erfindung sieht in ihrem Grundgedanken vor, dass im Inneren der Mulde zwei das in einer zum Türblatt parallelen Ebene angeordnete Ritzel zwischen sich einfassende, jeweils eine in die Außenverzahnung des Ritzels eingreifende Verzahnung aufweisende und dadurch bei Drehung des Ritzels eine gegenläufige Bewegung ausführende Schieber längs verschiebbar angeordnet sind, von denen ein Schieber über einen jeweils gelenkig an ihm sowie an dem Hebelgriff angelenkten Verbinder mit dem Hebelgriff derart verbunden ist, dass die senkrecht zum Türblatt erfolgende Verschwenkung des Hebelgriffes in eine das Ritzel antreibende Längsverschiebung des an den Hebelgriff angeschlossenen Schiebers umgesetzt wird, wobei die Schieber an ihren aneinander gegenüberliegenden Enden das Türblatt in zugeordneten Ausnehmungen durchgreifende Anschlussgestaltungen zum Anschluss je einer innenseitig des Türblattes verlaufenden Verriegelungsstange aufweisen.The invention provides in its basic idea that inside the trough two arranged in a plane parallel to the door leaf pinion between them, each having a engaging in the outer toothing of the pinion teeth and thus during rotation of the pinion an opposing movement exporting slide longitudinally displaceable are arranged, of which a slider is connected via a respective hinged to it and to the lever handle connector with the lever handle such that the perpendicular to the door leaf successive pivoting of the lever handle is converted into a pinion driving longitudinal displacement of the slider connected to the slide, wherein the slide at their mutually opposite ends of the door leaf in associated recesses sweeping connection configurations for connecting each one inside the door leaf extending locking rod.

Mit der Erfindung ist der Vorteil verbunden, dass aufgrund der parallelen Ausrichtung des Ritzels zum Türblatt und dessen Anordnung innerhalb der Mulde die Bautiefe des Verschlusses verringert ist. Da weiterhin aufgrund der Anordnung des Ritzels auf dessen beiden Seiten entsprechende Schieber angeordnet sind, können auch zwei, in einer gegenläufigen Bewegung verschiebbare Verriegelungsstangen eingesetzt werden, die zudem nahe der Türblattebene geführt sein können, weil das Maß des Durchgriffs der Anschlussgestaltungen durch das Türblatt wählbar ist. Schließlich führt die Ausrichtung des zwischen dem Hebelgriff und dem angeschlossenen Schieber angeordneten Verbinders dazu, dass beim Schließen des Verschlusses durch Hineindrücken des Hebelgriffs in die Mulde dieser Verbinder gegen Ende des Eindrückweges nahezu die gleiche Kraftrichtung wie die Schieber aufweist, so dass zur Überwindung des beim Schließen der Tür am Ende des Schließvorganges auftretenden höchsten Dichtungsdrucks von dem Verschluss auch das höchste Drehmoment zur Verfügung gestellt ist.The invention has the advantage that due to the parallel orientation of the pinion to the door leaf and its arrangement within the trough, the overall depth of the closure is reduced. Further, since corresponding slides are arranged on both sides thereof due to the arrangement of the pinion, two locking bars displaceable in an opposite movement can also be used, which moreover can be guided close to the door leaf level, because the degree of penetration of the connection configurations through the door leaf can be selected , Finally, the orientation of the connector disposed between the lever handle and the connected slider causes the closing of the shutter by pushing the lever handle into the recess of this connector towards the end of the Eindrückweges almost the same direction of force as the slide, so that to overcome the closing the door at the end of the closing process occurring highest sealing pressure of the closure and the highest torque is provided.

Nach einem Ausführungsbeispiel der Erfindung ist vorgesehen, dass die Schieber jeweils an ihren beiden Enden einen nach innen einspringenden Vorsprung aufweisen.According to one embodiment of the invention, it is provided that the slides each have an inwardly projecting projection at their two ends.

Ein Ausführungsbeispiel der Erfindung sieht vor, dass die Anschlussgestaltungen an den nach innen einspringenden Vorsprüngen der beiden Schieber derart angebracht sind, dass die Anschlussgestaltungen für die in einer Flucht verlaufenden Verriegelungsstangen auf der Längsmittenachse der Mulde gelegen sind. Damit ist eine symmetrische Zuordnung von Mulde und zugeordneten Verriegelungsstangen gewährleistet, so dass die Mulde mit dem in ihr angeordneten Betätigungsmechanismus für die Verriegelungsstangen jeweils in einer um 180 Grad gedrehten Stellung eingesetzt werden kann, ohne die Anordnung der in einer Flucht liegenden Verriegelungsstangen anpassen zu müssen.An embodiment of the invention provides that the connection configurations are mounted on the inwardly-projecting projections of the two slides such that the connection configurations for the aligned locking rods are located on the longitudinal center axis of the trough. This is a symmetrical assignment of trough and associated locking rods ensures that the trough can be used with the arranged therein locking bar actuation mechanism in a rotated position by 180 degrees, without having to adjust the arrangement of the aligned locking bars.

Weiterhin ist nach einem Ausführungsbeispiel der Erfindung vorgesehen, dass die Anschlussgestaltungen gabelförmig mit Gabelschenkeln und einer stirnseitig zwischen den Gabelschenkeln gelegenen Öffnung zur formschlüssigen und lösbaren Aufnahme der zugeordneten Verriegelungsstange oder eines Teils davon ausgebildet sind. Da die Verriegelungsstangen in der Regel an der Innenseite des Türblatts über daran befestigte Stangenführungen fixiert sind, ist mit dieser Gestaltung der Vorteil verbunden, dass der Verschluss ohne ein vorheriges Lösen der Verriegelungsstangen von dem Verschlussmechanismus von dem Türblatt abgenommen werden kann. Bei der Montage braucht die Mulde mit den über ihre Bodenplatte vorstehenden Anschlussgestaltungen lediglich auf das Türblatt aufgelegt zu werden, weil sich die das Türblatt durchstoßenden offenen Gabelschenkel über die zugeordnete Verriegelungsstange oder einen Teil davon schieben. Da die Kraftrichtung der Verriegelungsstange parallel zur Türblattebene und damit senkrecht zur Verbindungsrichtung zwischen Mulde und Verriegelungsstange ausgerichtet ist, sind für die Funktion des Verschlusses mit angeschlossenen Verriegelungsstangen keine weiteren Maßnahmen erforderlich. Hierdurch ist die Montage bzw. die Demontage wesentlich erleichtert.Furthermore, according to an embodiment of the invention, it is provided that the connection configurations are fork-shaped with fork legs and an end face between the fork legs opening for the positive and releasable receiving the associated locking rod or a part thereof. Since the locking bars are usually fixed to the inside of the door panel via rod guides attached thereto, this design has the advantage that the closure can be removed from the door panel without a prior release of the locking bars from the locking mechanism. During assembly, the trough needs to be placed on the door leaf with the above its bottom plate protruding connection configurations, because the door leaf piercing the open fork leg on the associated locking bar or a part thereof to push. Since the force direction of the locking rod is aligned parallel to the door leaf plane and thus perpendicular to the connecting direction between the trough and locking bar, no further action is required for the function of the closure with connected locking rods. As a result, the assembly and disassembly is much easier.

Weiterhin kann vorgesehen sein, dass der am Hebelgriff angelenkte Verbinder an dem nach innen einspringenden Vorsprung des an den Hebelgriff angeschlossenen Schiebers angelenkt ist.Furthermore, it can be provided that the articulated on the lever handle connector is hinged to the inwardly projecting projection of the slider connected to the lever.

Im Hinblick auf eine bestmögliche Kraftrichtung beim Schließen des Verschlusses ist nach einem Ausführungsbeispiel der Erfindung vorgesehen, dass der mit dem Verbinder verbundene Vorsprung des an den Hebelgriff angeschlossenen Schiebers so weit nach innen einspringt, dass die Verbindung von Schieber und Verbinder unter der Längsachse des Hebelgriffes liegt.With regard to the best possible direction of force when closing the closure is provided according to an embodiment of the invention, that of the connector connected to the projection of the slider connected to the lever so far inwards that the connection of slider and connector lies below the longitudinal axis of the lever handle.

In einer Ausführungsform der Erfindung kann vorgesehen sein, dass der an seinem einen Ende mittels einer Lagerachse an dem Hebelgriff schwenkbar angelenkte Verbinder an seinem anderen Ende gabelförmig ausgebildet ist und mit seinen Gabelschenkeln einen an dem Vorsprung des Schiebers befindlichen Ansatz einschließt, wobei ein die Gabelschenkel und den Ansatz durchstoßender Lagerstift zur Ausbildung einer Schwenklagerung zwischen Verbinder und Schieber vorgesehen ist.In one embodiment of the invention it can be provided that at its one end by means of a bearing axis pivotally hinged to the lever handle connector at its other end is fork-shaped and includes with its fork legs located on the projection of the slide approach, wherein the fork legs and the approach piercing bearing pin is provided to form a pivotal mounting between the connector and slider.

Die beiden Schieber 22 und 23 sind dabei derart angeordnet, dass sie bei einer Drehung des Ritzels 20 jeweils eine gegenläufige Bewegung zueinander ausführen. Die Schieber 22 und 23 weisen an ihren beiden gegenüberliegenden Enden jeweils einen nach innen einspringenden Vorsprung 31 auf.In the interior of the trough 10, a pinion 20 is arranged with an external toothing 21 in a not shown to the door leaf or to the bottom of the recess 12 of the trough 10 parallel alignment. On both sides of the pinion 20 in the recess 12 of the trough 10 in the longitudinal direction slidable slide 22 and 23 are arranged, which are each provided on its side facing the pinion 20 with a toothing 24 in a permanent engagement with the external teeth 21 of the pinion 20th stands. The two slides 22 and 23 are arranged such that they each perform an opposite movement to each other upon rotation of the pinion 20. The slides 22 and 23 have at their two opposite ends in each case an inwardly projecting projection 31.

Der eine Schieber 22 ist über einen gelenkig an ihm angeschlagenen Verbinder 25 gelenkig mit dem Hebelgriff 13 verbunden. So ist das eine Ende 26 des Verbinders 25 mittels einer Lagerachse 27 gelenkig mit dem Hebelgriff 13 verbunden, während das gegenüberliegende Ende 28 des Verbinders 25 gabelförmig mit voneinander beabstandeten Gabelschenkeln 29 ausgebildet ist. Die Gabelschenkel 29 umfassen einen an dem zugeordneten Vorsprung 31 des Schiebers 22 angeordneten, sich in Längsrichtung der Mulde 10 erstreckenden Ansatz 32, wobei der Ansatz 32 sowie die Gabelschenkel 29 von einem Lagerstift 30 durchstoßen sind derart, dass der Verbinder 25 gelenkig an den Schieber 22 angeschlossen ist.The one slider 22 is pivotally connected via a hinged to him connector 25 with the lever handle 13. Thus, one end 26 of the connector 25 is pivotally connected to the lever handle 13 by means of a bearing shaft 27, while the opposite end 28 of the connector 25 is fork-shaped with each other spaced fork legs 29 is formed. The fork legs 29 comprise a arranged on the associated projection 31 of the slider 22, extending in the longitudinal direction of the trough 10 projection 32, wherein the neck 32 and the fork legs 29 are pierced by a bearing pin 30 such that the connector 25 hinged to the slider 22nd connected.

Die beiden Schieber 22 und 23 weisen an ihren einander gegenüberliegenden Enden Anschlussgestaltungen 33 auf, die den Boden der Mulde 10 sowie bei an einem Türblatt montierter Mulde auch das Türblatt in zugeordneten Durchbrüchen durchstoßen, so dass an den Anschlussgestaltungen 33 jeweils nicht dargestellte Verriegelungsstangen anschließbar sind. Hierzu sind die Anschlussgestaltungen 33 gabelförmig mit Gabelschenkeln 34 und einer dazwischen liegenden Öffnung ausgebildet, so dass an die Gabelschenkel 34 in einer lösbaren Verbindung jeweils ein Ende einer zugeordneten Verriegelungsstange anschließbar ist. Soweit bei dem vorbeschriebenen Verschluss vorgesehen ist, dass die Verriegelungsstangen in einer Flucht auf der Längsmittenachse der Mulde 10 gelegen sind, sind die Anschlussgestaltungen 33 auch an der dem Türblatt zugewandten Unterseite der Vorsprünge 31 der beiden Schieber 22 und 23 angeordnet. Weiterhin hat die gabelförmige Ausbildung der Anschlussgestaltungen mit einer zwischen den Gabelschenkeln 34 liegenden Öffnung den technischen Hintergrund, dass die Anschlussgestaltungen 33 bei der Montage der Mulde 10 an einem Türblatt lediglich über die an der Innenseite des Türblatts vormontierten Verriegelungsstangen geschoben werden muss, so dass sich eine lediglich formschlüssige und lösbare Verbindung zwischen Anschlussgestaltungen 33 und Verriegelungsstangen ergibt. Diese Verbindung kann jeweils allein durch Aufstecken bzw. Abnehmen der Mulde 10 von dem Türblatt hergestellt bzw. aufgehoben werden.The two slides 22 and 23 have at their opposite ends connecting configurations 33 which pierce the bottom of the trough 10 and mounted on a door leaf well and the door leaf in associated openings, so that at the connection configurations 33 locking bars not shown are connected. For this purpose, the connection configurations 33 are fork-shaped with fork legs 34 and an opening located therebetween, so that in each case one end of an associated locking rod can be connected to the fork legs 34 in a releasable connection. As far as provided in the above-described closure that the locking bars are located in alignment with the longitudinal center axis of the trough 10, the connection configurations 33 are also arranged on the underside of the projections 31 of the two slides 22 and 23 facing the door leaf. Furthermore, the fork-shaped design of the connection configurations with an opening lying between the fork legs 34 has the technical background that the connection configurations 33 must be pushed during assembly of the trough 10 on a door leaf only on the pre-assembled on the inside of the door latch bars, so that a only positive and detachable connection between connection configurations 33 and locking rods results. This connection can be made or removed in each case solely by attaching or removing the trough 10 of the door leaf.

Der vorstehend beschriebene versenkbare Verschluss funktioniert dabei wie folgt: Ausgehend von einer in der Zeichnung nicht dargestellten, jedoch anhand der Beschreibung nachvollziehbaren Schließstellung des Verschlusses mit einem in die Vertiefung 12 der Mulde 10 eingeklappten Griffhebel 13 führt eine Betätigung des Zylinderschlosses 16 über die entsprechend beaufschlagte Hebelverriegelung 17 zu einer Freigabe des Hebelgriffes 13, der unter der Wirkung der ihn vorspannenden Feder 15 zunächst seine aus der Zeichnung ersichtliche Handhabungsstellung einnimmt. Ein weiteres Herausschwenken des Hebelgriffes 13 aus der Mulde 10 zur Öffnung des Verschlusses wird unmittelbar über den an den Hebelgriff 13 angeschlossenen Verbinder 25 in eine Längsverschiebung des an den Verbinder 25 angeschlossenen Schiebers 22 (in der Zeichnung nach links) umgesetzt, der seinerseits über den Eingriff seiner Verzahnung 24 mit der Außenverzahnung 21 des Ritzels 20 das Ritzel 20 dreht, welches bei seiner Drehung durch Eingriff seiner Außenverzahnung 21 in die Verzahnung 24 des gegenüberliegenden Schiebers 23 auch für eine gegenläufige Verschiebung des Schiebers 23 (in der Zeichnung nach rechts) sorgt. Aufgrund der Bewegung der Schieber 22 und 23 werden die Anschlussgestaltungen 33 aufeinander zubewegt, so dass daran angehängte Verriegelungsstangen ebenfalls in eine Entriegelungsstellung bewegt werden.The retractable closure described above works as follows: Starting from a not shown in the drawing, but with reference to the description of the comprehensible closed position of the closure with a folded into the recess 12 of the trough 10 handle lever 13 performs an operation of the Cylinder lock 16 via the corresponding acted lever lock 17 to a release of the lever handle 13, which initially assumes its apparent from the drawing handling position under the action of him biasing spring 15. Further pivoting out of the lever handle 13 from the trough 10 to the opening of the closure is immediately converted via the connector 25 connected to the lever handle 13 in a longitudinal displacement of the connected to the connector 25 slider 22 (in the drawing to the left), in turn via the engagement its toothing 24 with the external teeth 21 of the pinion 20, the pinion 20 rotates, which in its rotation by engagement of its external teeth 21 in the teeth 24 of the opposite slide 23 for an opposite displacement of the slider 23 (in the drawing to the right). Due to the movement of the sliders 22 and 23, the connecting structures 33 are moved toward each other so that locking bars attached thereto are also moved to an unlocking position.

Zum Schließen des Verschlusses wird der Hebelgriff 13 in Richtung der Mulde 10 bewegt, und diese Bewegung wird ebenfalls in eine gegenläufige Längsverschiebung der Schieber 22 und 23 umgesetzt, so dass die daran befindlichen Anschlussgestaltungen 33 auseinandergedrückt und die daran angehängten Verriegelungsstangen in die Verriegelungsposition verschoben werden. Es ist erkennbar, dass gegen Ende des Eindrückweges der Verbinder 25 nahezu eine gleiche Kraftrichtung wie der Verlauf der beiden Schieber 22, 23 aufweist, so dass der Hebelgriff 13 das maximale Drehmoment dann ausübt, wenn beim Schließen der Tür bzw. deren Verriegelung der höchste Dichtungsdruck überwunden werden muss. Bei Erreichen der Handhabungsstellung ist die Schließstellung der Verriegelungsstangen erreicht, und der Hebelgriff 13 kann entgegen der Wirkung der Feder 15 in die Vertiefung 12 der Mulde 10 hineingedrückt werden, bis er mit der Hebelverriegelung 17 verrastet.To close the shutter, the lever handle 13 is moved in the direction of the trough 10, and this movement is also converted into an opposite longitudinal displacement of the slide 22 and 23, so that the connection configurations located thereon 33 pressed apart and the attached locking rods are moved to the locking position. It will be appreciated that towards the end of the push-in stroke, the connector 25 will have nearly the same direction of force as the two sliders 22, 23, so that the lever handle 13 will apply the maximum torque when the highest seal pressure is applied when the door is closed must be overcome. Upon reaching the handling position, the closed position of the locking rods is reached, and the lever handle 13 can be pressed against the action of the spring 15 in the recess 12 of the trough 10 until it locks with the lever lock 17.
