Description

Die Erfindung betrifft einen versenkbaren Verschluß für Schaltschranktüren o. dgl., mit einem Schließteil, der einen Vorreiber zur mittigen Verriegelung und/oder vom Schließteil nach oben bzw. unten sich erstreckende Stangen zum oberen bzw. unteren Verriegeln der Tür aufweist, wobei der Schließteil eine durch das Türblatt nach außen führende Betätigungswelle besitzt, an der eine Handhabe in Form eines Griffhebels befestigt ist, der an seinem einen Ende an der Betätigungswelle um eine zur Betätigungswellenachse senkrechte Achse schwenkbar angelenkt ist, und an seinem anderen Ende eine im verschlossenen Zustand in Richtung des Türblattes weisenden, mit einer Aufnahme für ein Schloß wie Zylinderschloß o. dgl. versehenen Vorsprung aufweist, und wobei am Türblatt ein plattenartiger Aufsatz oder Platte vorgesehen ist, die eine den Vorsprung passend aufnehmende Einsenkung zum verschließbaren Aufnehmen des Vorsprungs besitzt, die die Türblattebene nach innen durchstößt.The invention relates to a retractable closure for control cabinet doors or the like, with a locking part which has a sash for central locking and / or rods extending upwards or downwards from the locking part for upper or lower locking of the door, the locking part being a through the door leaf leading to the outside actuating shaft, to which a handle in the form of a handle lever is attached, which is pivoted at one end to the actuating shaft about an axis perpendicular to the actuating shaft axis, and at the other end in the closed state in the direction of The door leaf facing, with a receptacle for a lock such as a cylinder lock or the like. Provided projection, and wherein a plate-like attachment or plate is provided on the door leaf, which has a recess corresponding to the projection for the lockable receiving of the projection, which the door leaf plane inwards pierces.

Verschlüsse für Schaltschranktüren od. dgl. sind bereits in vielen Varianten bekannt, siehe beispielsweise die deutsche Gebrauchsmusterschrift 7 621 270.Locks for control cabinet doors or the like are already known in many variants, see for example the German utility model 7 621 270.

Derartige Verschlüsse sind meist mit einem Knebelgriff versehen, der auch abnehmbar sein kann, um ein unautorisiertes Öffnen zu verhindern.Such closures are usually provided with a toggle handle, which can also be removable to prevent unauthorized opening.

Nachteilig bei einer derartigen Türsicherung ist, daß Ersatzgriffe ziemlich leicht beschafft und dann doch der Schrank von einer nicht dazu berechtigten Person geöffnet werden kann, so daß der eigentliche Sicherungszweck verfehlt wird. Um diese Nachteile zu vermeiden, hat man bereits, gemäß einem der Anmelderin bekannten Vorschlag (der die im Oberbegriff des Anspruchs 1 genannten Merkmale aufweist), der Handhabe die Form eines Griffhebels gegeben, der an seinem einen Ende an der Betätigungswelle um eine zur Wellenachse senkrechte Achse schwenkbar angelenkt ist und an seinem anderen Ende einen im verschlossenen Zustand in Richtung des Türblattes weisenden, mit einer Aufnahme für ein Zylinderschloß o. dgl. versehenen Vorsprung aufweist, während am Türblatt ein Aufsatz vorgesehen ist, der eine den Vorsprung passend aufnehmende Einsenkung zum verschließbaren Aufnehmen des Vorsprungs besitzt, wie dies aus der DE-GM-7 014 950 in ähnlicher Art beschrieben ist.A disadvantage of such a door lock is that replacement handles can be obtained fairly easily and the cabinet can then be opened by an unauthorized person, so that the actual security purpose is missed. In order to avoid these disadvantages, according to a proposal known to the applicant (which has the features mentioned in the preamble of claim 1), the handle has been given the shape of a handle lever, which at one end on the actuating shaft is perpendicular to the shaft axis Axis is pivotally articulated and has at its other end a in the closed state in the direction of the door leaf, provided with a receptacle for a cylinder lock or the like. Projection is provided on the door leaf, which has a recess that fits the projection to the closable Receiving the projection has, as described in a similar manner from DE-GM-7 014 950.

Durch diese Anordnung kann der Verschluß mit Hilfe eines regulären Schlosses, wie Zylinderschlosses gesichert werden, so daß der Verschluß den gleichen Sicherheitsgrad gegenüber unautorisiertem Öffnen besitzt, wie andere mit Hilfe von Zylinderschlössern o. dgl. abschließbare Türen.With this arrangement, the lock can be secured by means of a regular lock, such as a cylinder lock, so that the lock has the same level of security against unauthorized opening as other doors which can be locked by means of cylinder locks or the like.

Zwar gibt es bereits Knebelverschlüsse, die mit Hilfe von Zylinderschlössern gesichert werden, wobei derartige Verschlüsse beispielsweise für Fahrzeuggaragentüren angewendet werden. Diese Art Verschlüsse weist jedoch noch den Nachteil auf, daß man an Vorsprüngen der Knebelverschlüsse mit Kleidungsstücken o. dgl. hängenbleiben kann, was im Gefahrenfalle von großem Nachteil sein kann. Insbesondere bei Schaltschranktüren muß nämlich dann, wenn diese in Fluchtwegen angeordnet werden, sichergestellt sein, daß derartige vorspringende hakenförmige Gebilde, wie Betätigungsknebel, an denen Kleidungsstücke o. dgl. hinterhaken könnten, nicht vorhanden sind.There are already toggle locks that are secured with the help of cylinder locks, such locks being used for example for vehicle garage doors. However, this type of fastener still has the disadvantage that it can get caught on projections of the toggle fasteners with clothing or the like, which can be a great disadvantage in the event of danger. In the case of control cabinet doors in particular, if these are arranged in escape routes, it must be ensured that such projecting hook-shaped structures, such as actuating toggles, on which items of clothing or the like could hook behind, are not present.

Die in der geschilderten Weise verbesserte Konstruktion mit der versenkbaren Handhabe zeigt keine derartigen gefährlichen Vorsprünge, hat aber noch einige Nachteile, deren Beseitigung Aufgabe der vorliegenden Erfindung ist.The construction with the retractable handle improved in the manner described does not show such dangerous projections, but still has some disadvantages, the remedy of which is the object of the present invention.

Wesentlichster Nachteil ist die umständliche Montage mit Hilfe von mehreren Schraubbolzen, für die im Türblatt zudem mehrere Durchbrüche vorgesehen werden müssen, was auch den weiteren Nachteil mangelnder Dichtigkeit des Türblatts im Verschlußbereich ergibt. Außerdem ergeben diese Schraubbolzen einen Spannungsverschleppungsweg von innen nach außen, was bei Verwendung des Verschlusses für Türen von elektrische Einrichtungen enthaltenden Schaltschränken untragbar sein kann.The most important disadvantage is the cumbersome assembly with the aid of several bolts, for which several openings must also be provided in the door leaf, which also has the further disadvantage that the door leaf is not tight in the closure area. In addition, these bolts result in a voltage carryover path from the inside to the outside, which can be prohibitive when using the lock for doors of electrical cabinets containing electrical devices.

Aufgabe der Erfindung ist die Schaffung eines versenkbaren Verschlusses für Schaltschranktüren o. dgl. der oben geschilderten Art, der diese Nachteile vermeidet.The object of the invention is to provide a retractable closure for control cabinet doors or the like. The type described above, which avoids these disadvantages.

Gelöst wird die Aufgabe dadurch, daß die Einsenkung des plattenartigen Aufsatzes einen im wesentlichen kreisförmigen äußeren Querschnitt aufweist und ein Umfangsgewinde besitzt; der plattenartige Aufsatz mit dem Lagergehäuse der Betätigungswelle einstückig ausgebildet ist, und das Lagergehäuse der Betätigungswelle einen die Türblattebene nach innen durchstoßenden Teil aufweist, der einen kreisförmigen, gewünschtenfalls mit Einschnürungen versehenen Außenquerschnitt und ein Außengewinde besitzt, so daß der plattenartige Aufsatz an zwei Stellen mittels aufgeschraubten Befestigungsmuttern befestigbar ist.The object is achieved in that the depression of the plate-like attachment has a substantially circular outer cross section and has a circumferential thread; the plate-like attachment is formed in one piece with the bearing housing of the actuating shaft, and the bearing housing of the actuating shaft has a part penetrating the door leaf plane inwards, which has a circular, if necessary provided with constrictions, external cross-section and an external thread, so that the plate-like attachment is screwed on at two points Fastening nuts can be fastened.

Auf diese Weise werden besondere Befestigungsschraubbolzen mit den damit verbundenen Nachteilen wie umständliche Montage, Undichtigkeiten und Gefahr der Spannungsverschleppung von inneren, elektrisch leitenden Teilen des Schaltschrankverschlusses auf von außen zugänglichen Teile des Verschlusses, wie Befestigungsschraubbolzen vermieden. Diese Spannungsverschleppung kann insbesondere dann auftreten, wenn innerhalb des Schaltschrankes abgerissene Drähte mit metallischen Teilen des Verschlusses, wie beispielsweise den Befestigungsbolzen, in Berührung kommen.In this way, special fastening bolts with the associated disadvantages such as cumbersome installation, leaks and the risk of voltage spreading from inner, electrically conductive parts of the control cabinet lock to parts of the lock that are accessible from the outside, such as fastening bolts, are avoided. This carryover of voltage can occur in particular when wires torn off inside the control cabinet come into contact with metallic parts of the closure, such as the fastening bolts.

Besonders günstig ist, daß bei der jeweils für das Lager der Betätigungswellen sowie für den das Zylinderschloß o. dgl. aufnehmenden Vorsprung eine kreisförmige Durchbrechung im Türblatt vorgesehen und Lager bzw. nach innen durchstoßender Vorsprung jeweils mit einem Außengewinde versehen werden können, auf das eine entsprechend passende Schraubenmutter aufgesetzt wird, um auf diese Weise den Verschluß am Türblatt festzulegen. Zum einen ergibt dies eine besonders sichere und einfachere Anbringung, zum anderen kann dadurch auch in sehr simpler Weise eine wasser-, staub- und luftdichte Abschließung des auf der einen Seite des Türblattes liegenden Bereiches von dem auf der anderen Türblattseite liegenden Bereich vorgenommen werden, beispielsweise dadurch, daß der durch die Türblattebene nach innen durchstoßende Vorsprung mit Hilfe eines mit Innengewinde versehenen Bechers befestigt wird. Besteht dieser Becher aus isolierendem Material, beispielsweise aus isolierendem Kunststoff, wird gleichzeitig noch in einfacher Weise eine weitere Sicherung gegenüber Spannungsverschleppung auf das meist metallische Zylinderschloß erreicht. Die Dichtheit läßt sich durch Anwendung von Dichtungen wie O-Ring-Dichtungen oder Dichtungsblätter in Form der Auflagefläche für die Verschlußaußenteile verbessern. Soll der Verschluß für begehbare Zellen verwendet werden, ist es günstig, gemäß einer noch anderen Ausführungsform der Erfindung den Verschluß mit einer Panik-Schloßeinrichtung in Form eines zwischen Schließteil und Betätigungswelle vorgesehenen Freilaufs von z. B. 90° zu versehen, derart, daß der Verschluß auch bei Verriegelung der äußeren Handhabe von innen geöffnet werden kann.It is particularly favorable that a circular opening is provided in the door leaf for the bearing of the actuating shafts and for the projection receiving the cylinder lock or the like, and bearings or inwards penetrating projection can be provided with an external thread, on which a correspondingly suitable screw nut is placed, in order in this way to fix the closure on the door leaf. On the one hand, this results in a particularly secure and simple attachment, on the other hand, it can also be carried out in a very simple manner, for example, to make the area on one side of the door leaf watertight, dustproof and airtight in that the projection penetrating through the door leaf plane is fastened with the aid of an internally threaded cup. If this cup consists of insulating material, for example of insulating plastic, at the same time a further protection against the spread of voltage on the mostly metallic cylinder lock is achieved in a simple manner. The tightness can be improved by using seals such as O-ring seals or sealing sheets in the form of the contact surface for the outer parts of the closure. If the closure is to be used for walk-in cells, it is expedient, according to yet another embodiment of the invention, the closure with a panic lock device in the form of a freewheel provided, for example, between the closure part and the actuating shaft. B. 90 °, such that the closure can be opened from the inside even when the outer handle is locked.

Ein weiterer Vorteil des erfindungsgemäßen Verschlusses besteht noch darin, daß er auch zur Befestigung eines Stangenverschlusses dienen kann, sofern dieser mit einer Unterfütterung versehen ist, die auf der Innenfläche des Türblattes aufliegt, weil dann mit Hilfe der den Verschluß befestigenden Schraubenmutter auch die Stangenverschluß-Unterfütterung gehalten werden könnte.Another advantage of the closure according to the invention is that it can also be used to fasten a rod lock, provided that it is provided with a lining that rests on the inner surface of the door leaf, because then with the help of the screw nut fastening the lock, the rod closure relining could be held.

Im einzelnen ist in Fig. 1 ein Stangenverschluß 10 zu erkennen, der die Tür 16 mit Hilfe von Stangen 28, 30 am Türrahmen 36 verriegelt, wobei die Stangen nahe ihrer Enden in geeigneter Weise, beispielsweise mittels Stangenführungen 40 an der Tür 16 geführt werden.1 shows a rod lock 10 which locks the door 16 to the door frame 36 with the aid of rods 28, 30, the rods being guided near the ends in a suitable manner, for example by means of rod guides 40 on the door 16.

Üblicherweise wird man neben den beiden Verschlußstangen 28, 30 noch einen Vorreiber 32 vorsehen, um die Tür auch auf etwa halber Höhe mit dem Türrahmen 36 verriegeln zu können, siehe auch die Fig. 2 und 3, die eine Ansicht von vorn bzw. eine Ansicht von oben auf den Verschluß der Fig. 1 wiedergeben.Usually, in addition to the two locking rods 28, 30, a sash 32 is also provided in order to be able to lock the door at about half the height with the door frame 36, see also FIGS. 2 and 3, which are a front view and a view play from above on the closure of FIG. 1.

Wie den Fig. 1 bis 3 zu entnehmen ist, ist der Schließteil 12 des Verschlusses 10 verhältnismäßig einfach aufgebaut und besteht im wesentlichen aus einer durch das Türblatt 16 nach außen führenden Betätigungswelle 14, die in einem Lagergehäuse 18 um zumindest 90° drehbar gelagert ist, wobei die Drehwinkelbegrenzung beispielsweise mittels einer nicht näher dargestellten Nase am inneren Ende der Betätigungswelle 14 bewirkt wird, die an Anschlagflächen 20, 22 des Lagergehäuses 18 anschlägt. Dieses innere Ende der Betätigungswelle 14 trägt auch einen doppelarmigen Hebel 24, an dessen freien Enden jeweils eine Betätigungsstange 28 bzw. 30 angelenkt ist. Der Hebel 24 kann einstückig in den Vorreiber 32 übergehen.As can be seen in FIGS. 1 to 3, the closing part 12 of the closure 10 is of relatively simple construction and essentially consists of an actuating shaft 14 leading through the door leaf 16, which is rotatably mounted in a bearing housing 18 through at least 90 °, wherein the rotation angle limitation is effected, for example, by means of a nose (not shown in more detail) at the inner end of the actuating shaft 14, which strikes against stop surfaces 20, 22 of the bearing housing 18. This inner end of the actuating shaft 14 also carries a double-armed lever 24, at the free ends of which an actuating rod 28 or 30 is articulated. The lever 24 can merge into the cam 32 in one piece.

Das Gehäuse 18 besitzt ein Außengewinde 26 für eine Befestigungsmutter 27 zum Verschrauben des Gehäuses 18 nach Hindurchstecken des Gehäuses 18 durch einen entsprechenden Durchbruch im Türblatt 16.The housing 18 has an external thread 26 for a fastening nut 27 for screwing the housing 18 after the housing 18 has been pushed through a corresponding opening in the door leaf 16.

Wie insbesondere aus Fig. 1 deutlich hervorgeht, ist am nach außen stehenden Ende der Betätigungswelle 14 mittels eines Stiftes 34 eine Handhabe 38 in der Form eines Griffhebels derart angelenkt, daß der Griffhebel 38 zum eine zur Wellenachse senkrechte Achse schwenkbar ist. Entsprechend weist auch das Lagergehäuse 18 eine nach außen sich öffnende Mulde 42 mit ungefähr halbkugelförmiger Profilierung auf, in der die passend halbkugelförmig ausgebildete Endfläche der Handhabe 38 passend eingelegt ist. Auf diese Weise kann die Handhabe 38 sowohl um die Achse des Stiftes 34 verschwenkt als auch um die Achse der Betätigungswelle 14 gedreht werden.As is particularly clear from FIG. 1, a handle 38 in the form of a handle lever is articulated at the outward end of the actuating shaft 14 by means of a pin 34 in such a way that the handle lever 38 can be pivoted to an axis perpendicular to the shaft axis. Correspondingly, the bearing housing 18 also has an outwardly opening trough 42 with an approximately hemispherical profile, in which the appropriately hemispherical end surface of the handle 38 is suitably inserted. In this way, the handle 38 can be pivoted both about the axis of the pin 34 and rotated about the axis of the actuating shaft 14.

Am anderen Ende der Handhabe 38 befindet sich ein Vorsprung 44, der bei der in Fig. 1 dargestellten Verschließstellung der Handhabe 38 in Richtung des Türblattes 16 weist und von einem Aufsatz 46 aufgenommen wird, der durch einen entsprechenden Durchbruch des Türblattes 16 nach innen reicht. Dieser nach innen reichende Teil des Aufsatzes 46 bildet eine Einsenkung 45 mit kreisförmigem Außenquerschnitt und einem Außengewinde 48, auf das eine Mutter ähnlich der Mutter 27 oder aber, wie dargestellt, eine mit Innengewinde versehene becherartige Mutter 50 aufgeschraubt werden kann, so daß sich ein unter Umständen gas-, staub- oder feuchtigkeitsdichter Abschluß der Durchbruchsöffnung im Türblatt 16 ergibt. Die Höhe dieser Bechermutter 50 sollte nicht größer sein als es der Abstand der Stange 28 vom Türblatt 16 zuläßt, weil sonst der Aufsatz 46 nicht im Bereich der Stange 28 montiert werden könnte, wie es bei der Ausführungsform gemäß Fig. 1 bis 3 der Fall ist. Äquivalent zum Aufschrauben des Bechers 50 wären andere Befestigungsarten des Bechers an der Einsenkung, die aber ungünstiger handhabbar sind. Das untere Ende der Handhabe 38 besitzt noch eine Aufnahme 52 für ein Zylinderschloß 54 o. dgl., dessen Verschlußfinger 56 beim Verschließen mittels eines Zylinderschlüssels in eine Bahn mit einer Anschlagfläche 58 gelangt, die ein Herausziehen des Vorsprungs 44 aus dem Aufsatz 46 in bekannter Weise verhindert. Aus Stabilitätsgründen und zur Vereinfachung der Montage ist es zweckmäßig, gemäß der in den Fig. 1 bis 3 dargestellten Ausführungsform eine auf dem Türblatt 16 aufsetzbare Platte 60 vorzusehen, die an ihrem einen, gemäß Fig. 1 oberen Ende in das Lagergehäuse 18 und an ihrem anderen, unteren Ende in den Aufsatz 46 einstückig übergeht. Die Platte 60 könnte auf dem Türblatt 16 mittels hier nicht dargestellter Senkkopfschraube o. dgl. aufgeschraubt oder aber auch aufgeschweißt oder aufgeklebt sein. Viel besser ist jedoch die dargestellte Ausführungsform gemäß der Erfindung, bei der die Befestigung der Platte 60 dadurch bewirkt wird, daß einerseits das Lagergehäuse 18 mittels einer Mutter 27 und andererseits der die Türblattebene nach innen durchstoßende Einsenkung 49 mittels der Bechermutter 50 festgelegt ist.At the other end of the handle 38 there is a projection 44 which, in the closed position of the handle 38 shown in FIG. 1, points in the direction of the door leaf 16 and is received by an attachment 46 which extends inwards through a corresponding opening in the door leaf 16. This inwardly extending part of the attachment 46 forms a depression 45 with a circular outer cross-section and an external thread 48, onto which a nut similar to the nut 27 or, as shown, an internally threaded cup-like nut 50 can be screwed on, so that an under Circumstances gas, dust or moisture-tight closure of the opening in the door leaf 16 results. The height of this cup nut 50 should not be greater than the distance of the rod 28 from the door leaf 16, otherwise the Attachment 46 could not be mounted in the area of the rod 28, as is the case with the embodiment according to FIGS. 1 to 3. Other types of attachment of the cup to the depression would be equivalent to screwing the cup 50 on, but these are less convenient to handle. The lower end of the handle 38 also has a receptacle 52 for a cylinder lock 54 or the like, the locking finger 56 of which, when closed by means of a cylinder key, comes into a path with a stop surface 58, which pulls the projection 44 out of the attachment 46 in a known manner prevented. For reasons of stability and to simplify assembly, it is expedient, in accordance with the embodiment shown in FIGS. 1 to 3, to provide a plate 60 which can be placed on the door leaf 16 and which at its one end, as shown in FIG. 1, into the bearing housing 18 and at its top other, lower end in one piece in the attachment 46. The plate 60 could be screwed onto the door leaf 16 by means of a countersunk screw or the like, not shown here, or else welded or glued on. Much better, however, is the illustrated embodiment according to the invention, in which the attachment of the plate 60 is effected in that on the one hand the bearing housing 18 is fixed by means of a nut 27 and on the other hand the depression 49 penetrating the door leaf plane inwards is fixed by means of the cup nut 50.

Es wurde schon ausgeführt, daß es günstig ist, wenn die Bechermutter 50 zum Türblatt 16 einen dichten Verschluß bildet, weil dadurch der Durchtritt von schädlichen Gasen, Feuchtigkeit und Staub durch den im Türblatt 16 für die Einsenkung 45 gebildeten Durchbruch verhindert wird, und zwar gilt das für beide Richtungen. Erreicht werden könnte dieser dichte Abschluß beispielsweise dadurch, daß die Bechermutter aus einem zumindest im Randbereich etwas nachgiebigen Kunststoffmaterial gefertigt wird, wobei zur zusätzlichen Abdichtung noch der auf dem Türblatt 16 aufliegende Rand der Bechermutter 50 eine nachgiebige Lippe (nicht dargestellt) aufweisen kann.It has already been stated that it is advantageous if the cup nut 50 forms a tight seal with the door leaf 16, because this prevents the passage of harmful gases, moisture and dust through the opening formed in the door leaf 16 for the depression 45, specifically that for both directions. This tight seal could be achieved, for example, by producing the cup nut from a plastic material which is somewhat flexible at least in the edge area, the edge of the cup nut 50 resting on the door leaf 16 also having a flexible lip (not shown) for additional sealing.

Eine andere Möglichkeit wäre die Zwischenlage eines Dichtungsblattes 47, siehe Fig. 4, zwischen Außenfläche des Türblatts 16 und Auflagefläche der Platte 60 bzw. des plattenartigen Aufsatzes 46, wobei das Dichtungsblatt 47 das gleiche Lochbild wie das Türblatt aufweist.Another possibility would be the interposition of a sealing sheet 47, see FIG. 4, between the outer surface of the door sheet 16 and the contact surface of the plate 60 or the plate-like attachment 46, the sealing sheet 47 having the same hole pattern as the door sheet.

Daß es günstig ist, die Bechermutter aus isolierendem Material, beispielsweise isolierendem Kunststoff zu fertigen, wurde bereits eingangs dargelegt. Durch diese isolierende Becherkonstruktion wird nämlich sicher verhindert, daß beispielsweise innerhalb eines Schaltschrankes abgerissene, spannungsführende Drähte mit dem meist metallischen Schließzylinder 54 Kontakt erhalten und dadurch eine Bedienungsperson gefährdet wird, wenn diese einen meist gleichfalls aus Metall bestehenden Schlüssel in das Zylinderschloß 54 einführt.That it is cheap to manufacture the cup nut from insulating material, for example insulating plastic, has already been explained at the beginning. This insulating cup construction reliably prevents, for example, torn-off, live wires within a control cabinet from contacting the mostly metallic locking cylinder 54 and thereby endangering an operator if he inserts a key, which is also usually made of metal, into the cylinder lock 54.

Aus dem gleichen Grunde ist es günstig, wenn auch die Handhabe 38 sowie der plattenartige Aufsatz 46 aus Kunststoffmaterial bestehen, weil man aus Stabilitätsgründen die Betätigungswelle 14 wie auch die daran angebrachte Vorreiberzunge 32 (sowie auch den doppelarmigen Hebel 24 mit den daran angebrachten Stangen 28, 30) aus Metall fertigen wird und daher dann, wenn auch die Handhabe 38 aus (elektrisch leitendem) Metall bestehen würde, wiederum ein Verschleppungsweg für gefährliche elektrische Spannungen nach außen zur Verfügung stehen würde.For the same reason, it is favorable if the handle 38 and the plate-like attachment 46 are made of plastic material, because for reasons of stability the actuating shaft 14 and the cam tongue 32 attached to it (as well as the double-armed lever 24 with the rods 28 attached to it) 30) is made of metal and therefore, if the handle 38 were also made of (electrically conductive) metal, a carry-over path would again be available for dangerous electrical voltages to the outside.

Um auch den erfindungsgemäßen Verschluß im Bereich der Betätigungswelle 14 gas-, staubund wasserdicht zu machen, könnte im Bereich des Türblattdurchbruches für die Betätigungswelle 14 innerhalb des plattenartigen Aufsatzes 46 eine Ringnut 62 zur Aufnahme eines Dichtringes wie auch innerhalb des Lagergehäuses 18 eine entsprechende Nut zur Aufnahme einer O-Ring-Dichtung 64 vorgesehen sein.In order to make the closure according to the invention in the area of the actuating shaft 14 gas, dust and waterproof, in the area of the door leaf opening for the actuating shaft 14 inside the plate-like attachment 46 an annular groove 62 for receiving a sealing ring and also within the bearing housing 18 could have a corresponding groove for receiving an O-ring seal 64 may be provided.

Die Fig. 4 zeigt in einer ähnlichen Ansicht wie Fig. 1 eine andere Ausführungsform des erfindungsgemäßen Schaltschranktürverschlusses, wobei der Verschluß 10 hier eine etwas kompliziertere Form mit herausnehmbaren Stangen 28, 30, einer Stangenverschluß-Unterfütterung 66 sowie einer Panik-Einrichtung 78 aufweist. Durch die Unterfütterung 66 wird eine sichere Lagerung des Verschlusses 10 auch bei dieser schwereren Ausführungsform gewährleistet, wobei gleichzeitig ein ausreichender Abstand für den Verschluß 10 und damit der Stange 28, 30 vom Türblatt 16 gesorgt wird, der angesichts der nach innen vorspringenden Teile des plattenartigen Aufsatzes 46 zweckmäßig ist.FIG. 4 shows, in a view similar to FIG. 1, another embodiment of the control cabinet door lock according to the invention, the lock 10 here having a somewhat more complicated shape with removable bars 28, 30, a bar lock relining 66 and a panic device 78. The relining 66 ensures secure storage of the closure 10 even in this heavier embodiment, while at the same time providing a sufficient distance for the closure 10 and thus the rod 28, 30 from the door leaf 16, which in view of the inwardly projecting parts of the plate-like attachment 46 is appropriate.

Eine ähnliche Unterfütterung zeigt auch die in Fig. 5 dargestellte Ausführungsform, wobei jedoch dort die Unterfütterung 66 nicht beispielsweise mittels besonderer (nicht dargestellter) Schrauben oder Verschweißungen auf dem Türblatt befestigt ist, sondern von der Mutter 27 gehalten wird, die auch das Lagergehäuse 18 und damit den plattenartigen Aufsatz 46 des erfindungsgemäßen Verschlusses hält. Zu diesem Zweck ist die Unterfütterung 66 mit einem den Bereich des Lagergehäuses 18 überspannenden Bügelblech 68 versehen, das einen ähnlichen Durchbruch wie das Türblatt 16 für das Lagergehäuse 18 besitzt, so daß nach Aufschrauben der Mutter 27 das Bügelblech 68 fest am Türblatt 16 zu liegen kommt. Zur Erhöhung der Steifigkeit des Bügelbleches 68 kann dieses an der einen Seite noch senkrecht von der Türblattebene 16 weggebogen sein, siehe Bezugszahl 70.A similar relining is also shown in the embodiment shown in FIG. 5, however the relining 66 there is not fastened to the door leaf, for example, by means of special screws (not shown) or welded, but is held by the nut 27, which also supports the bearing housing 18 and thus holding the plate-like attachment 46 of the closure according to the invention. For this purpose, the relining 66 is provided with a bracket plate 68 spanning the area of the bearing housing 18, which has a breakthrough similar to that of the door leaf 16 for the bearing housing 18, so that after the nut 27 is screwed on, the bracket plate 68 comes to rest firmly on the door leaf 16 . To increase the rigidity of the bracket plate 68, this can be bent perpendicularly away from the door leaf plane 16 on one side, see reference number 70.

Es könnte sein, daß bei der Herstellung des Türblatts bereits ein Befestigungsloch für einen üblichen Vorreiberverschluß vorgesehen wurde. Dieses Befestigungsloch ist aus Gründen der Drehsicherung mit mindestens einer, meistens vier sehnenartigen Einschnürungen versehen, an die der Außenumfang des durchsteckbaren Teils des Verschlusses angepaßt ist.It could be that a fastening hole for a conventional sash lock was already provided in the manufacture of the door leaf. For reasons of anti-rotation, this fastening hole is provided with at least one, usually four tendon-like constrictions, to which the outer circumference of the push-through part of the closure is adapted.

Soll nun dieses Türblatt statt mit dem normalen Vorreiberverschluß mit dem erfindungsgemäßen versenkbaren Verschluß versehen werden, braucht nur noch der zweite Durchbruch für die Einsenkung 45 angebracht zu werden, während auf eine Nacharbeit beim ersten Durchbruch für das Betätigungswellenlager verzichtet werden kann, falls der Querschnitt des Außenumfangs dieses Lagers vorsorglich die gleiche Form erhalten hat, wie die des üblichen Vorreiberverschlusses, obwohl hier die Drehsicherung nicht benötigt wird.Now is this door leaf instead of the normal cam lock with the fiction, ge As can be provided retractable closure, only the second opening for the recess 45 needs to be made, while reworking for the first opening for the actuating shaft bearing can be dispensed with if the cross section of the outer circumference of this bearing has been given the same shape as that the usual cam lock, although the anti-rotation lock is not required here.

Die beiden Fig. 4 und 5 zeigen sehr deutlich die Panik-Einrichtung, die dazu dient, den Verschluß 10 auch dann von innen öffnen zu können, wenn von außen her der Verschluß durch Einschieben des Vorsprungs 44 in den Aufsatz 46 verriegelt ist, so daß ein versehentlich in einem begehbaren Schaltschrank Eingeschlossener sich wieder befreien kann. Er kann dies durch Betätigung eines Hebels 72, der auf einer aus dem Verschlußteil 10 vorspringenden Vierkant-Betätigungswelle 74 drehstarr aufgesetzt ist. Diese Betätigungswelle 74 betätigt direkt den Stangenverschluß 10 mit den Stangen 28, 30 und dem Vorreiber und tritt auf der anderen Seite des Verschlußkastens 10 wieder aus, um dort in einer Freilauf-Einrichtung 80 zu münden, bestehend beispielsweise aus einer ersten, mit der Vierkant-Betätigungswelle 74 drehstarr verbundenen Kupplungsscheibe 82 und einer zweiten mit der Betätigungswelle 14 für die Handhabe 38 drehstarr verbundenen zweiten Kupplungsscheibe 84. Wenn man die eine Kupplungsscheibe 80 mit ein oder zwei Vorsprüngen versieht, die in entsprechenden Führungsnuten in der anderen Kupplungsscheibe begrenzter Winkelerstrekkung eingreifen, läßt sich erreichen, daß die beiden Scheiben 80, 84 zueinander um beispielsweise etwa 90° verschieblich sind, derart, daß mittels des Hebels 72 der Stangenverschluß 10 geöffnet und geschlossen werden kann, ohne daß sich dabei die Betätigungswelle 14 der Handhabe 38 drehen muß. Andererseits kann aber durch Verdrehen der Handhabe 38 um beispielsweise 180° (bei einem Freilaufwinkel von 90°) ebenfalls der Verschluß 10 geschlossen und geöffnet werden.The two FIGS. 4 and 5 show very clearly the panic device which serves to be able to open the closure 10 from the inside even when the closure is locked from the outside by inserting the projection 44 into the attachment 46, so that someone accidentally locked in a walk-in control cabinet can free himself again. He can do this by actuating a lever 72, which is mounted on a square actuating shaft 74 projecting from the closure part 10 in a rotationally rigid manner. This actuating shaft 74 directly actuates the rod lock 10 with the rods 28, 30 and the sash and exits again on the other side of the lock box 10 in order to open there in a freewheel device 80, consisting, for example, of a first one with the square Actuating shaft 74 torsionally rigid coupling disc 82 and a second with the actuating shaft 14 for the handle 38 torsionally rigidly connected second coupling disc 84. If one coupling disc 80 is provided with one or two projections which engage in corresponding guide grooves in the other coupling disc with limited angular extent, can achieve that the two disks 80, 84 are mutually displaceable by, for example, about 90 °, such that the rod lock 10 can be opened and closed by means of the lever 72 without the actuating shaft 14 of the handle 38 having to rotate. On the other hand, the closure 10 can also be closed and opened by rotating the handle 38 by, for example, 180 ° (with a free-running angle of 90 °).

Es sei noch erwähnt, daß für den Fall, daß die Dichtigkeit gegenüber der Schutzisolierung in der Bedeutung zurücktritt, anstelle der abdichtenden Kunststoffbecherbefestigungsmutter 50 auch eine normale Metallmutter ähnlich der Mutter 27 zur Befestigung der Einsenkung 45 benutzt werden kann, sofern der Vorsprung 44 eine das Zylinderschloß 54 becherförmig umschließende Gestalt erhält. Für den Daumen 49 (siehe Fig. 4) des Zylinderschlosses wäre dann eine seitliche schlitzförmige Öffnung im becherartigen Vorsprung 44 vorzusehen, damit der Daumen 49 hindurchtreten und in die Verschlußbahn 58 (Fig. 1) des Aufsatzes 49 einschwenken kann und den Hebel 38 verriegelt. Der (metallische) Daumen 49 wird isolierend von der Einsenkung 45 des plattenartigen Aufsatzes 46 abgedeckt. Der Schlitz bedingt allerdings eine Undichtigkeitsstelle. Der vorstehend beschriebene versenkbare Verschluß ist besonders vorteilhaft bei Blechtüren, wenn es besonders auf die günstige Zweilochbefestigung und die Dichtheit ankommt. Dabei ist es von untergeordneter Bedeutung, ob nun ein Zylinderschlüssel zum Verriegeln (wie dargestellt) oder die bei den normalen Vorreiberverschlüssen auch üblichen Vierkant-, Dreikant- und ähnliche Schlüssel verwendet werden.It should also be mentioned that in the event that the tightness against the protective insulation decreases in importance, instead of the sealing plastic cup fastening nut 50, a normal metal nut similar to the nut 27 can also be used for fastening the depression 45, provided that the projection 44 locks the cylinder lock 54 cup-shaped shape. For the thumb 49 (see FIG. 4) of the cylinder lock, a lateral slit-shaped opening in the cup-like projection 44 would then have to be provided, so that the thumb 49 can pass through and swivel into the closure track 58 (FIG. 1) of the attachment 49 and lock the lever 38. The (metallic) thumb 49 is insulated from the depression 45 of the plate-like attachment 46. However, the slot causes a leak. The retractable closure described above is particularly advantageous for sheet metal doors when it comes down to the cheap two-hole fastening and the tightness. It is of secondary importance whether a cylinder key is used for locking (as shown) or the square, triangular and similar keys that are also used with the normal cam locks.

Wird bei Blechschaltschränken Schutzisolierung für den Verschluß vorgesehen, brauchen innenliegende Teile nicht schutzgeerdet zu werden.If protective insulation is provided for the lock in sheet metal cabinets, internal parts do not need to be earthed.

Bei Kunststoffschränken für elektrische Anlagen sollte der Verschluß in der beschriebenen Weise schutzisoliert sein, da eine Erdung des Verschlusses über das aus isolierendem Material bestehende Türblatt nicht möglich und eine besondere Erdungseinrichtung zu aufwendig ist.In the case of plastic cupboards for electrical systems, the lock should be insulated in the manner described, since it is not possible to ground the lock via the door leaf, which is made of insulating material, and a special grounding device is too expensive.

Der erfindungsgemäße Verschluß erlaubt somit in einfacher Weise nicht nur eine stabile und drehfeste Zwei-Loch-Befestigung, sondern gleichzeitig auch eine Abdichtung ohne aufwendige Zusatzmittel sowie auch eine Schutzisolation des Verschlusses gegen von z. B. innerhalb des Schaltschrankes losgerissene, unter Spannung stehende Drähte.The closure of the invention thus allows not only a stable and rotatable two-hole fastening in a simple manner, but also a seal without expensive additives and also a protective insulation of the closure against z. B. loosened, live wires inside the cabinet.

Außerdem kann durch teilweise Versenkung der Handhabe in den plattenartigen Aufsatz 46, wie z. B. Fig. 3 erkennen läßt, (der Aufsatz besitzt dann einen den in Ruhestellung befindlichen Griffhebel 38 an allen Seiten teilweise umschließenden Rand bzw. eine zumindest einen Teil des Griffhebels 38 aufnehmende Einsenkung) nicht nur Material eingespart werden, sondern die Bauhöhe wird auch niedriger und der in Ruhestellung befindliche Griffhebel bietet keine Angriffsfläche für gewaltsames Öffnen.In addition, by partially sinking the handle into the plate-like attachment 46, such as. B. Fig. 3 reveals, (the essay then has a handle lever 38 in the rest position at all sides partially enclosing edge or at least a part of the handle lever 38 receiving depression) not only material is saved, but the overall height is also lower and the handle lever, which is in the rest position, does not offer any surface for violent opening.
