Abstract

The lock includes an activation shaft connectable on the outside of the door with a lock activation, such as a handle, a cylinder lock, or similar, and is connected firmly at the interior with a friction tongue. The friction tongue is movable through turning the activation shaft between an unlocked position and a locked position. A relative movement of the casing with respect to the activation shaft (13) fixed in the locking position of the friction tongue (15) is enabled through the arrangement of the activation shaft in longitudinal direction of the casing (10). An element (20), giving to the relative movement, is arranged between activation shaft and casing.

Die Erfindung betrifft einen Vorreiberverschluß für eine Tür oder Klappe, insbesondere von Schaltschränken oder dergleichen, mit einem an dem Türblatt oder der Klappe festgelegten Gehäuse und mit einer in dem Gehäuse drehbar angeordneten Betätigungswelle, wobei die Bestätigungswelle außenseitig der Tür mit einer Schließbetätigung wie Griff, Zylinderschloß oder dergleichen koppelbar und innenseitig der Tür drehstarr mit einer Vorreiberzunge verbunden ist, die durch Drehung der Betätigungswelle zwischen einer Entriegelungsstellung und einer Verriegelungsstellung für die Tür oder Klappe bewegbar ist.The invention relates to a cam lock for a Door or flap, especially of control cabinets or the like, with one on the door leaf or the flap fixed housing and rotatable with one in the housing arranged actuation shaft, the confirmation shaft on the outside of the door with a locking mechanism such as a handle, Cylinder lock or the like can be coupled and inside the door is rigidly connected to a sash tongue, by rotating the actuating shaft between one Unlocking position and a locking position for the door or flap is movable.

Ein Vorreiberverschluß mit den vorgenannten Merkmalen ist in der EP 0 504 144 B1 beschrieben. In dem formschlüssig in einem zugeordneten Türdurchbruch festzulegenden Gehäuse des Vorreiberverschlusses ist eine an ihrem türaußenseitigen freien Ende mit einem Knebelhandgriff als Betätigung versehende Betätigungswelle drehbar gelagert; an ihrem anderen, türinnenseitigen Ende trägt die Betätigungswelle eine drehstarr mit ihr verbundene Vorreiberzunge, die durch Drehung des Knebelhandgriffes zwischen einer Entriegelungsstellung und einer Verriegelungsstellung für die Tür bewegbar ist. In der Verriegelungsstellung bei geschlossener Tür legt sich die Vorreiberzunge beispielsweise hinter eine Abkantung des Schrankkorpus und hält dadurch die Tür geschlossen. Der bekannte Vorreiberverschluß ist dabei an die Materialstärken und Formverhältnisse von Schrankkorpus und Türblatt derart angepaßt, daß bei geschlossener Tür und in die Verriegelungsstellung gedrehter Vorreiberzunge eine feste und dauerhafte Schließung des Schrankes gewährleistet ist.A cam lock with the aforementioned features is described in EP 0 504 144 B1. In the form-fitting in an assigned door opening housing to be determined Cam lock is one on the outside of the door free end with a toggle handle as actuation provided actuating shaft rotatably mounted; on her the other, inside the door carries the actuating shaft a serrated tongue connected to it by turning Rotation of the toggle handle between one Unlocking position and a locking position for the door is movable. In the locked position at When the door is closed, the sash tongue lies down for example behind a bend in the cabinet body and this keeps the door closed. The known Cam lock is based on the material thicknesses and Form relationships of cabinet body and door leaf like this adjusted that with the door closed and in the Locked position of the turned cam tongue a fixed and permanent closure of the cabinet is guaranteed.

In der praktischen Anwendung sind insbesondere bei Schaltschränken Anforderungen festzustellen, wonach bei einer im Inneren des Schaltschrankes eintretenden Explosion mit entsprechender Druckentwicklung die Tür sich kurzzeitig von dem Schrankkorpus abheben soll, um über einen so entstehenden Spalt den Explosionsdruck zu entspannen, ohne etwa vor dem Schrank stehende Personen durch eine gewaltsame vollständige Türöffnung zu gefährden. Nach Entspannung des Explosionsdruckes soll die Tür im wesentlichen normal aufzuschließen sein. Der Erfindung liegt daher die Aufgabe zugrunde, einen unter im Schaltschrank herrschenden Innendruck eine spaltweise Türöffnung ermöglichenden Vorreiberverschluß zur Verfügung zu stellen. In practical use, in particular Control cabinets determine what after an explosion occurring inside the control cabinet with corresponding pressure development the door temporarily should stand out from the cabinet body in order to over a so resulting gap to relax the explosion pressure without for example, people standing in front of the closet endanger violent full door opening. To Relief of the explosion pressure is said to be in the door must be essentially unlockable normally. The invention is therefore the task of one under the Control cabinet prevailing internal pressure a gap Door lock that allows the door to be opened to deliver.

Die Lösung dieser Aufgabe ergibt sich einschließlich vorteilhafter Ausgestaltungen und Weiterbildungen der Erfindung aus dem Inhalt der Patentansprüche, welcher dieser Beschreibung nachgestellt sind.The solution to this problem is inclusive advantageous refinements and developments of Invention from the content of the claims, which follow this description.

Die Erfindung sieht in ihrem Grundgedanken vor, daß aufgrund einer längsverschiebbaren Anordnung der Betätigungswelle in dem Gehäuse eine Relativverschiebung des Gehäuses zur in der Verriegelungsstellung der Vorreiberzunge festgelegten Betätigungswelle ermöglicht ist und daß in gegenseitiger Abstützung zwischen Betätigungswelle und Gehäuse ein einer Relativverschiebung nachgebendes Element angeordnet ist. Wenn somit auf das Türblatt mit daran befestigtem Gehäuse beispielsweise durch eine auftretende Explosion ein nach außen gerichteter Druck ausgeübt wird, kann sich das Gehäuse gegenüber der durch die sich in der Verriegelungsstellung befindliche Vorreiberzunge festgehaltenen Betätigungswelle relativ verschieben, so daß sich der Abstand zwischen Gehäuse und Vorreiberzunge vergrößern und sich die Tür trotz verriegelter Vorreiberzunge um ein dem konstruktiv eingestellten Verschiebeweg entsprechendes Maß von dem Schrankkorpus abheben kann. Läßt der auf die Tür einwirkende Druck nach, ist der Vorreiberverschluß durch Drehen der Betätigungswelle in die Entriegelungsstellung der Vorreiberzunge zu bringen, so daß die Tür normal geöffnet werden kann.The basic idea of the invention provides that due to a longitudinally displaceable arrangement of the Actuating shaft in the housing a relative displacement of the housing in the locked position Sash tongue fixed actuation shaft is enabled and that in mutual support between Actuating shaft and housing a relative displacement yielding element is arranged. If so on that Door leaf with attached housing, for example an explosion occurs an outward pressure is exercised, the housing can oppose the through the one in the locked position Locking tongue held actuating shaft relatively move so that the distance between the housing and Enlargement tongue and enlarge the door despite locked sash tongue around a constructive set displacement corresponding dimension of the Cabinet body can lift off. Let him on the door pressure after, the sash lock is through Turn the actuating shaft to the unlocked position bring the sash tongue so that the door is normal can be opened.

Nach einem Ausführungsbeispiel der Erfindung ist vorgesehen, daß das nachgebende Element aus einem sich unter Last verformenden Material besteht; die Verformung des nachgebendes Elementes muß dabei den erforderlichen Verschiebeweg des Gehäuses gegenüber der Betätigungswelle zur Verfügung stellen.According to an embodiment of the invention provided that the compliant element from one material deforming under load; the deformation the yielding element must be the required Displacement of the housing in relation to the actuating shaft provide.

Soweit nach einem alternativen Ausführungsbeispiel der Erfindung vorgesehen ist, daß das nachgebende Element aus einem unter Last zerstörbaren Material besteht, ist der erforderliche Verschiebeweg aufgrund des Fortfalls des nachgebenden Elementes gut einstellbar.As far as an alternative embodiment of the Invention is provided that the compliant element is a material that can be destroyed under load required displacement due to the disappearance of the yielding element easily adjustable.

Es kann auch vorgesehen sein, daß das nachgebende Element als federndes Bauteil ausgebildet ist. Hiermit ist der Vorteil verbunden, daß nach Beendigung des einwirkenden Druckes die gespannte Feder sich wieder entspannt und dabei zu einem erneuten Schließen der Tür führt, die durch den Vorreiberverschluß im übrigen leicht öffen- und schließbar ist, weil das federnde Element selbst im Rahmen des eingebauten Vorreiberverschlusses keine Vorspannung entfaltet. Hierbei kann es zweckmäßig sein, daß das nachgebende Element als auf die Betätigungswelle aufgesteckte Federhülse ausgebildet ist.It can also be provided that the compliant element is designed as a resilient component. This is the Advantage associated that after the acting Pressure the tensioned spring relaxes again while doing so leads to the door being closed again by the The sash lock can also be easily opened and closed is because the resilient element itself under the built-in cam lock no preload unfolded. It may be appropriate that the yielding element as on the actuating shaft plugged spring sleeve is formed.

In the drawing, exemplary embodiments of the invention are shown, which are described below. Show it:
Fig. 1
a cam lock with rotary actuation in an exploded view,
Fig. 2
a lockable by means of a cylinder lock cam lock in a representation corresponding to FIG. 1.

Wie zunächst aus Fig. 1 zu entnehmen ist, besteht der Vorreiberverschluß aus einem Gehäuse 1, welches in eine entsprechend geformte Öffnung eines nicht dargestellten Türblattes einsetzbar ist und sich auf der Vorderseite der Tür mit einem entsprechend ausgebildeten Flansch abstützt. Von der Rückseite der Tür ist das Gehäuse 10 über eine aufzuschraubende Überwurfmutter 11 an dem nicht dargestellten Türblatt festzulegen. In dem Gehäuse 10 ist ein Betätigungsansatz 12 zum Ansetzen eines entsprechenden Betätigungsschlüssels gelagert, der mit einer einstückig angebrachten Betätigungswelle 13 durch das Gehäuse 10 reicht und türinnenseitig über das Gehäuse 10 hervorsteht. Das türinnenseitige Ende der Betätigungswelle 13 weist einen Vierkantansatz 14 auf, auf den eine Vorreiberzunge 15 mit einer Vierkantausnehmung 16 aufgesteckt ist, so daß sich eine drehstarre Verbindung zwischen Betätigungswelle 13 und Vorreiberzunge 15 ergibt. Die Vorreiberzunge 15 ist auf der Betätigungswelle 13 mittels einer axial eingedrehten Befestigungsschraube 17 verbunden, die stirnseitig eine Sperrverzahnung 18 aufweist, so daß eine Selbstlösung der Befestigungsschraube 17 vermieden ist. An der Vorreiberzunge 15 ist ein Vorsprung 26 ausgebildet, der in eine sich über 90° erstreckende Nut 27 des Gehäuses 10 eingreift, womit eine Verdrehbegrenzung der Vorreiberzunge 15 gegenüber dem Gehäuse 10 verwirklicht ist. As can first be seen from FIG. 1, the Cam lock from a housing 1, which in a appropriately shaped opening of a not shown Door leaf can be used and located on the front of the Support the door with an appropriately designed flange. From the back of the door, the housing 10 is over a screw nut 11 on the not set door leaf shown. In the housing 10 is an actuating approach 12 for setting a corresponding Actuator key stored in one piece attached operating shaft 13 through the housing 10 is sufficient and protrudes on the inside of the door over the housing 10. The inside of the door of the actuating shaft 13 has a square neck 14 on which a sash tongue 15th is plugged with a square recess 16 so that there is a torsionally rigid connection between the actuating shaft 13 and sash tongue 15 results. The sash tongue 15 is on the actuating shaft 13 by means of an axial screwed fastening screw 17 connected, the has a locking toothing 18 on the end face, so that a Self-loosening of the fastening screw 17 is avoided. On the sash tongue 15 is formed a projection 26 which into a groove 27 of the housing 10 which extends over 90 ° intervenes, thus limiting the turn of the sash tongue 15 compared to the housing 10 is realized.

Auf die Betätigungswelle 13 ist ein hülsenartiges Element 20 aufgesteckt, welches sich an seinem einen Ende gegen den Betätigungsansatz 12 der Betätigungswelle 13 abstützt und mit seinem anderen Ende gegen eine Distanzscheibe 19 des Gehäuses 10 abgestützt ist, so daß das aus einem zerstörbaren Material bestehende Element 20 zwischen dem Gehäuse 10 und der Betätigungswelle 13 eingespannt ist. Das Element 20 besteht aus einem unter Last zerstörbarem Material, beispielsweise einem geeigneten Keramikmaterial.On the actuating shaft 13 is a sleeve-like element 20 attached, which is at one end against the Actuating approach 12 supports the actuating shaft 13 and with its other end against a spacer 19 of the Housing 10 is supported, so that from a destructible material existing element 20 between the Housing 10 and the actuating shaft 13 is clamped. The Element 20 consists of a destructible under load Material, for example a suitable ceramic material.

Befindet sich der in Fig. 1 dargestellte und in einem Schrank mit Tür eingebaute Verschluß in der Verriegelungsstellung der Vorreiberzunge 15, so übt ein durch eine Explosion im Inneren des Schaltschrankes hervorgerufener Druck eine Flächenbelastung auf das Türblatt aus und will das Türblatt mit dem daran befestigten Gehäuse 10 in Richtung der Türöffnung verschieben. Da die Betätigungswelle 13 mit der an ihr befestigten und in der Verriegelungsstellung befindlichen Vorreiberzunge 15 unverschieblich festgehalten wird, drückt das Gehäuse 10 über die Distanzscheibe 19 auf das Element 20 aus zerstörbarem Material, welches bei Erreichen des vorbestimmten Druckes zerstört wird, so daß das Gehäuse 10 sich gegenüber der festliegenden Betätigungswelle 13 über einen etwa der axialen Länge des Elementes 20 entsprechenden Verschiebeweg relativ verschieben kann, so daß die Tür um einen den Verschiebeweg entsprechenden Spalt sich öffnet und der Explosionsdruck sich entspannen kann.Is the one shown in Fig. 1 and in one Closet with built-in lock in the door Locking position of the sash tongue 15, so practice due to an explosion inside the control cabinet created pressure a wing loading on the Door leaf and wants the door leaf with it on it attached housing 10 in the direction of the door opening move. Since the actuating shaft 13 with the on it attached and in the locked position Locking tongue 15 is held firmly, presses the housing 10 via the spacer 19 on the element 20 of destructible material, which when reaching the predetermined pressure is destroyed so that the housing 10th over against the fixed actuating shaft 13 approximately the axial length of the element 20 can move the corresponding displacement relatively that the door by a gap corresponding to the displacement opens and the explosion pressure can relax.

Bei dem in Fig. 2 dargestellten Ausführungsbeispiel ist das wiederum über eine Überwurfmutter 11 an dem nicht dargestellten Türblatt festgelegte Gehäuse 10 mit einer solchen axialen Länge ausgebildet, daß es in sich in einem ersten Aufnahmeraum 24 ein mit Schlüssel 22 zu betätigendes Zylinderschloß 21 aufnehmen kann, ferner in einem weiteren Aufnahmeraum 25 die von dem Zylinderschloß 21 mittels eines Adapters 23 in Drehung zu versetzende Betätigungswelle 13, an der wiederum wie zu Fig. 1 beschrieben die Vorreiberzunge 15 drehstarr befestigt ist. Bei diesem Ausführungsbeispiel stützt sich wiederum das Element 20 zwischem dem Tiefsten des Aufnahmeraumes 25 des Gehäuses 10 und der Betätigungswelle 13 ab.In the embodiment shown in FIG. 2, this is again via a union nut 11 on the not shown door leaf fixed housing 10 with a formed such an axial length that it is in itself in one first receiving space 24 to be operated with a key 22 Cylinder lock 21 can accommodate, further in another Recording space 25 by the cylinder lock 21 by means of a Adapter shaft 23 to be rotated, on the in turn as described in Fig. 1 Locking tongue 15 is fixed in a torsionally rigid manner. With this The embodiment in turn supports the element 20 between the deepest of the receiving space 25 of the housing 10 and the actuating shaft 13.

Es ergibt sich eine gleiche Funktion wie bereits zu Fig. 1 beschrieben.The same function results as for FIG. 1 described.

Die in der vorstehenden Beschreibung, den Patentansprüchen und der Zeichnung offenbarten Merkmale des Gegenstandes dieser Unterlagen können einzeln als auch in beliebigen Kombinationen untereinander für die Verwirklichung der Erfindung in ihren verschiedenen Ausführungsformen wesentlich sein.In the above description, the claims and the drawing disclosed features of the object These documents can be used individually or in any Combinations with each other for the realization of the Invention in its various embodiments be essential.
