Abstract
Description
Die Erfindung bezieht sich auf ein absperrbares Gerät mit einer Sperrvorrichtung für ein Handbedienungsorgan, das am Gerät in einem berandeten Bedienfeld, beispielsweise in einer Greifmulde, angeordnet ist, dessen Rand zumindest ein Paar gegenüberliegender Plombierlöcher aufweist.The invention relates to a lockable device with a locking device for a manual control element, which is arranged on the device in a bordered control panel, for example in a gripping trough, the edge of which has at least a pair of sealing holes located opposite one another.
Bei einem derartigen bekannten absperrbaren Gerät mit Sperrvorrichtung (DE-U-8 509 543) ist neben dem Handbedienungsorgan eines Leitungsschutzschalters auf seiner Ausschaltseite eine Klappe gelagert, die sich der Mulde des Schutzkragens anpaßt. Die Klappe kann mittels eines Fensters das Handbedienungsorgan in seiner Ausschaltstellung durch Umlegen übergreifen und das Handbedienungsorgan gegen Einschalten sichern. Eine derartige Vorrichtung ist in der Regel in der Fertigung einzusetzen. Sie eignet sich weniger für mehrfaches Einsetzen und Abnehmen durch Servicepersonal.In such a known lockable device with a locking device (DE-U-8 509 543), in addition to the manual control element of a circuit breaker, a flap is mounted on its switch-off side, which adapts to the trough of the protective collar. The flap can overlap the manual control element in its switched-off position by flipping it over and secure the manual control element against switching on. Such a device is generally used in production. It is less suitable for repeated insertion and removal by service personnel.
Bei verschiedenartigsten Geräten besteht einerseits Veranlassung, diese gegen unbefugtes oder versehentliches Bedienen zu sperren und andererseits lohnt es mitunter nicht, eine aufwendige Schloßmechanik vorzusehen. So ist es beispielsweise bei elektrischen Installationsgeräten wie Leitungsschutzschaltern erforderlich, diese bei Wartungsarbeiten gegen versehentliches oder leichtfertiges Wiedereinschalten zu sperren. Aus Platz- und aus Preisgründen ist es dabei oft nicht gut möglich, das Handbedienungsorgan durch eine eingebaute Schloßmechanik zu sperren.In the case of a wide variety of devices, there is occasion to lock them against unauthorized or accidental operation, and on the other hand it is sometimes not worthwhile to provide a complex lock mechanism. For example, it is necessary with electrical installation devices such as circuit breakers to lock them against unintentional or careless restarting during maintenance work. For space and price reasons, it is often not possible to lock the manual control element by means of a built-in lock mechanism.
In der Praxis wird daher häufig nur mit Tafeln gearbeitet, die über dem Gerät aufgehängt werden und auf denen Hinweise auf die Arbeiten stehen. Sie sind in der Regel mit der Aufforderung verbunden, die Anlage nicht wieder einzuschalten. Diese Maßnahmen geben in der Praxis häufig keinen ausreichenden Schutz.In practice, therefore, work is often only carried out with boards which are hung above the device and on which there are references to the work. As a rule, you are asked not to switch the system on again. These measures often do not provide adequate protection in practice.
Bei elektrischen Installationsgeräten, insbesondere bei Leitungsschutzschaltern, ist es an sich möglich, das Bedienen des Handbedienungsorgans durch einen in den Plombierlöchern des Schutzkragens durchgezogenen Plombierdraht zu verhindern. Auch dieser Schutz ist in der Praxis mitunter unzureichend und andererseits wird das Einführen eines Plombierdrahtes bei angereihten Geräten durch den Schutzkragen des benachbarten Gerätes oft stark behindert.In the case of electrical installation devices, in particular in the case of circuit breakers, it is in itself possible to operate the manual control element by means of a To prevent sealing holes of the protective collar solid sealing wire. This protection is also sometimes insufficient in practice, and on the other hand the insertion of a sealing wire in the case of devices in series is often severely hampered by the protective collar of the neighboring device.
Der Erfindung liegt die Aufgabe zugrunde, für ein absperrbares Gerät mit Plombierlöchern eine zuverlässigere und bequemere Sperrvorrichtung zu entwickeln, die leicht anzubringen und mittels Werkzeug leicht zu entfernen ist.The invention has for its object to develop a more reliable and convenient locking device for a lockable device with sealing holes, which is easy to attach and easy to remove with a tool.
Die Lösung der geschilderten Aufgabe besteht nach der Erfindung darin, daß ein Abdeckkörper auf dem Rand des Bedienfeldes aufsteht und mit zumindest einem Paar Riegelgliedern, von denen zumindest je Paar eines beweglich ist, in die Plombierlöcher eingreifen kann, wobei jedem beweglichen Riegelglied ein mit Schüssel bedienbares Arretierungsmittel, wie eine Kurvenscheibe, zugeordnet, ist das die Beweglichkeit des Riegelgliedes in der Eingriffstellung blockiert.The solution to the described problem is according to the invention that a cover body stands on the edge of the control panel and can engage with at least one pair of locking members, of which at least one pair is movable, in the sealing holes, each movable locking member being operable with a bowl Associated with locking means, such as a cam, this blocks the mobility of the locking member in the engaged position.
Ein derartiger Abdeckkörper kann auf dem Rand des Bedienfeldes des Handbedienungsorgans leicht aufgesetzt und arretiert werden, womit leichtfertiges oder versehentliches Wiedereinschalten wesentlich erschwert wird. Das Handbedienungsorgan läßt sich damit auch sperren, wenn durch die Plombierlöcher ein Plombierdraht nicht oder nur sehr erschwert durchgezogen werden könnte, wie es bei elektrischen Installationsanlagen bei einer Abdeckung in einer Verteilung vorkommt, die bündig mit der Oberkante des Schutzkragens von Leitungsschutzschaltern abschließt. Auf dem Rücken des Abdeckkörpers können dabei übliche Hinweise auf Montagearbeiten oder andere Hinweise in Informationsfeldern gegeben werden. Solche Informationen lassen sich aufdrucken, aufkleben oder anderweitig befestigen.Such a cover body can be easily placed and locked on the edge of the control panel of the manual control element, which makes it very difficult to switch it on again inadvertently or inadvertently. The manual control element can also be locked if a lead wire could not be pulled through the sealing holes or only with great difficulty, as occurs in electrical installation systems with a cover in a distribution that is flush with the upper edge of the protective collar of circuit breakers. On the back of the cover body, usual information about assembly work or other information fields can be given. Such information can be printed, glued or otherwise attached.
Das Arretierungsmittel kann am Abdeckkörper gelagert sein und innerhalb von Schlitzdurchbrüchen des Abdeckkörpers mit Ausnehmungen für Stifte eines Steckschlüssels versehen sein. Hierdurch erzielt man mit einfachen und wirtschaftlichen Mitteln eine Absperrung des Abdeckkörpers. Die Arretierungsmittel können insbesondere nach Art einer Kurvenscheibe ausgebildet sein und in der Blockierstellung mit zwei Höckern oder einem verbreiterten Anlagebereich am Riegelglied anliegen, um das Arretierungsmittel in der Blockierstellung rüttelfest zu halten. Das Riegelglied kann mit einem Filmangußscharnier aus einer Seitenwand des Abdeckkörpers gebildet werden.The locking means can be mounted on the cover body and can be provided with recesses for pins of a socket wrench within slot openings in the cover body. As a result, the cover body is shut off with simple and economical means. The locking means can, in particular, be designed in the manner of a cam disc and, in the blocking position, bear against the locking member with two bumps or a widened contact area in order to hold the locking means in the blocking position in a vibration-proof manner. The locking member can be formed with a film gate hinge from a side wall of the cover body.
Wenn das Arretierungsmittel in Öffnungsrichtung durch einen Anschlag in seiner Bewegung begrenzt ist, stellt man sicher, daß auch unter Erschütterungen das Arretierungsmittel sich nicht aus dem Zugriffbereich für den Steckschlüssel hinausbewegen kann. Dadurch ist gewährleistet, daß sich der Abdeckkörper befugterweise auch wieder leicht entfernen läßt.If the locking means in the opening direction is limited in its movement by a stop, it is ensured that the locking means cannot move out of the access area for the socket wrench even when shaken. This ensures that the cover body can also be easily removed again by authorization.
Um die Absperrung im Bedarfsfall, also mit wirtschaftlichen Maßnahmen, noch sicherer zu machen, kann das Arretierungsmittel mit einer Griffrippe oberhalb des Rückens des Abdeckkörpers in Verbindung stehen, die in der Schließstellung an einer Rippe am Abdeckkörper anliegt. Durch fluchtende Löcher in Griffrippe und Rippe läßt sich dann der Bügel eines Bügelschlosses durchführen und der Abdeckkörper regulär versperren. Verständlicherweise könnte durch diese Löcher auch ein Plombierdraht durchgezogen werden.In order to make the barrier even safer when necessary, that is to say with economical measures, the locking means can be connected to a grip rib above the back of the cover body, which in the closed position rests against a rib on the cover body. Through aligned holes in the handle rib and rib, the shackle of a padlock can then be carried out and the cover body can be regularly blocked. Understandably, a sealing wire could also be pulled through these holes.

In Fig. 1 ist ein absperrbares Gerät 1, ein als Leitungsschutzschalter ausgebildetes elektrisches Gerät, mit einem Abdeckkörper 2 veranschaulicht. Das Handbedienungsorgan 3 des Gerätes 1 ist in einem berandeten Bedienfeld, im Ausführungsbeispiel in einer Greifmulde 4 angeordnet. Der Rand des Bedienfeldes weist ein Paar gegenüberliegender Plombierlöcher 5 auf. An Anschlußklemmen 6 kann das Gerät elektrisch angeschlossen und mit einem Fuß 7 auf Tragschienen befestigt werden. Der Abdeckkörper 2 steht auf dem Rand des Bedienfelds auf und kann mit Riegelgliedern 8 und 9 nach Fig. 2 durch Zapfen 10 in Plombierlöchern 5 eingreifen. Vom Paar aus Riegelglied 8 und Riegelglied 9 ist im Ausführungsbeispiel das Riegelglied 9 beweglich ausgebildet. Der Rand 11 des Abdeckkörpers 2 springt oberhalb der Zeichenebene - anhand von Fig. 2 orientiert - beim Riegelglied 8 und 9 nach innen zurück und hintergreift damit den Rand des zugeordneten Gerätes 1 nach den Fig. 1 und 3.In Fig. 1, a lockable device 1, an electrical device designed as a circuit breaker, with a
Durch einen Freischnitt 12 nach Fig. 2, der im Rand 11 senkrecht zum Rücken des Abdeckkörpers verläuft und unterhalb des Rückens horizontal zum Rücken des Abdeckkörpers weiterläuft, wird ein bewegliches Riegelglied 9 erzielt, wenn das Scharnier 13 im Sinne eines Filmangußscharniers bei entsprechendem Material ausreichend flexibel ist. Dem beweglichen Riegelglied 9 ist ein mit Schlüssel bedienbares Arretierungsmittel 14 nach Art einer Kurvenscheibe zugeordnet, das die Beweglichkeit des Riegelgliedes in der Eingriffstellung durch Verdrehen entgegen dem Uhrzeigersinn blockiert. Die Zapfen 10 greifen dann in die Plombierlöcher 5 des Gerätes nach Fig. 3 ein und halten den Abdeckkörper am Gerät fest.A free cut 12 according to FIG. 2, which runs in the
Das Arretierungsmittel 14 kann am Abdeckkörpers an einem Lagerzapfen 15 nach Fig. 4 gelagert sein. Innerhalb von Schlitzdurchbrüchen 16 nach Fig. 4 und 5 im Abdeckkörper kann das Arretierungsmittel 14 mit Ausnehmungen 17 nach den Fig. 3, 4 und 5 für Stifte eines Steckschlüssels versehen sein.The locking means 14 can be mounted on the cover body on a
Das Arretierungsmittel 14 nach Fig. 2 ist nach Art einer Kurvenscheibe ausgebildet, wobei zwei Höcker 18 in der Blockierstellung am beweglichen Riegelglied 9 anliegen. Mit einem solchen Arretierungsmittel, wobei die Höcker auch durch einen verbreitertem Anlagebereich ersetzt sein können, ist die Blockierstellung rüttelfest sichergestellt. Die Kurvenscheibe kann also nicht in Öffnungsrichtung wegrutschen. Entsprechend kann das Arretierungsmittel 14 in Öffnungsrichtung durch einen Anschlag 19 nach Fig. 2 in seiner Bewegung begrenzt werden, um in der Offenstellung auch unter Erschütterungen zu vermeiden, daß sich die Ausnehmungen 17 aus dem Schlitzbereich 16 hinausdrehen können, wonach der Schlüssel nicht mehr eingeführt werden könnte.The locking means 14 according to FIG. 2 is designed in the manner of a cam disc, two bumps 18 resting on the
