Die Betätigereinheit 1 umfaßt ein mittels eines aufgeschnitten dargestellten Deckels verschließbares Gehäuse 3, das auf der zu öffnenden Absperreinrichtung A, etwa einer Tür, etwa eine Schiebe- oder Schwenktür, einer Klappe od.dgl., befestigt wird. In dem Gehäuse 3 ist ein in seine Ausgangsposition federvorgespannter Betätiger 4 in einer Führung 5 verschiebbar geführt. Die Verschiebung des Betätigers 4 erfolgt beispielsweise durch Schwenken eines im Gehäuse 3 gelagerten Handgriffs 6 etwa um 90°, wobei diese Schwenkbewegung über einen Hebel- oder einen Zahnstangentrieb 7a, 7b in eine Linearbewegung des Betätigers 4 umgesetzt wird, so daß der Betätiger 4 durch einen im Gehäuse 3 vorgesehenen Schlitz (in der Darstellung von
Die Zuhalteeinheit 2 umfaßt ebenfalls ein mittels eines nicht dargestellten Deckels 10 verschließbares Gehäuse 8, das über zwei Aufnahmeöffnungen 9 für Befestigungsschrauben an einem feststehenden Teil B, an dem die zu öffnende Absperreinrichtung A vorgesehen ist, etwa einem Schutzgitter, einem Tür- oder Klappenrahmen, insbesondere aus Metallprofilen od.dgl., befestigbar ist. Das Gehäuse 8 weist (nicht dargestellte) Aufnahmeöffnungen für Befestigungselemente, etwa Schrauben, zum Befestigen des Deckels 10 auf. Die Aufnahmeöffnungen 9 sind zweckmäßigerweise in Bewegungsrichtung des Betätigers 4 als Langlöcher ausgebildet, um eine entsprechende Justierung zu ermöglichen. Außerdem ist es vorteilhaft, die Aufnahmeöffnungen 9 mittig zur Längsmittelebene des Gehäuses 8 anzuordnen und wenigstens eine Aufnahmeöffnung 9 als Schutz gegen Manipulation durch den Deckel 10 abzudecken.The locking unit 2 also comprises a closable by means of a
Das Gehäuse 8 besitzt einen seitlichen Schlitz 11 einer Höhe, die erheblich, z.B. um 50% größer als die Höhe des Betätigers 4 ist, und einer Breite, die demgegenüber relativ wenig Spiel zur Breite des Betätigers 4 aufweist. Spiegelsymmetrisch zum Schlitz 11 kann in der gegenüberliegenden Seitenwandung des Gehäuses 8 ein weiterer entsprechender Schlitz vorgesehen sein, damit die Zuhalteeinheit 2 sowohl von recht wie von links benutzbar ist.The
Im Gehäuse 8 befindet sich benachbart zu einer Zwischenwandung 12 ein eine Ankerstange 13 aufweisender, etwa von einer im Gehäuse 8 befestigten Halterung 14 aufgenommener Elektromagnet 15, wobei sich die Ankerstange 13 senkrecht zur Bewegungsrichtung des Betätigers 4 erstreckt.In the
Benachbart zu dem bzw. den Schlitzen 11 ist im Gehäuse 8 ein Riegel 16 um eine sich parallel zur Bewegungsrichtung des Betätigers 4 erstreckende Drehachse schwenkbar. Beim dargestellten Ausführungsbeispiel wird die Drehachse durch zwei seitliche Zapfen 17 des Riegels 16 gebildet, die von Ausnehmungen 18 (in
Der Riegel 16 ist an der dem Elektromagneten 15 zugewandten Ende mit einer dem Betätiger 4 zugewandte Gabel 20 versehen, vgl.
Der Betätiger 4 besitzt an der dem Riegel 16 zugewandten Seite ein oder mehrere, im dargestellten Ausführungsbeispiel zwei Nuten 23, die durch einen Steg 24 voneinander getrennt sind. Die Nuten 23 und der Steg 24 erstrecken sich senkrecht zur Bewegungsrichtung des Betätigers 4 und bilden Eingriffsflächen für den Riegel 16. Dieser ist mit korrespondierenden Eingriffsflächen in Form von den Nuten 23 entsprechenden Vorsprüngen 25 versehen, die durch eine dem Steg 24 entsprechende Nut 26 voneinander getrennt sind.The
Bei in die Zuhalteeinheit 2 eingeschobenem Betätiger 4 kann daher der Riegel 16 formschlüssig unter der Vorspannung der auf die Ankerstange 13 wirkenden Feder 22 einfallen und den Betätiger 4 verriegelt halten. Ein Lösen des Riegels 16 geschieht dann über eine Strombeaufschlagung des Elektromagneten 15.When inserted into the locking unit 2
Der Betätiger 4 besitzt zweckmäßigerweise eine dem Riegel 16 zugewandte Schräge 27, durch die der Riegel 16 gegen die ihn beaufschlagende Federkraft zurück gedrückt werden kann, bevor er in die Nuten 23 des Betätigers 4 einfällt.The
Die Nuten 23 verlaufen zweckmäßigerweise an der dem Steg 24 abgewandten Seite schräg nach außen, wobei die Vorsprünge 25 des Riegels 16 korrespondierend gestaltet sind. Hierdurch läuft die Schräge 27 des Betätigers 4 auf eine Schräge 28 des entsprechenden Vorsprungs 25 auf. Riegel 16 und Betätiger 4 lassen sich bei dem dargestellten Ausführungsbeispiel sowohl rechts wie links verwenden.The
Dadurch, daß die Vorsprünge 25 auf der Länge der Nuten 23 irgendwo mit diesen in Verriegelungseingriff gelangen können, ist die Anordnung der Betätigereinheit 1 zur Zuhalteeinheit 2 innerhalb der möglichen Grenzen nicht kritisch, d.h. diese beiden Einheiten können höhenmäßig entsprechend gegeneinander versetzt sein, ohne daß das Zusammenwirken beeinträchtigt wird, solange der Betätiger 4 in den benachbarten Schlitz 11 einschiebbar ist.The fact that the
Die Eingriffsflächen von Betätiger 4 und Riegel 16 können auch komplementär zu der gezeichneten Ausführungsform angeordnet sein.The engagement surfaces of
Der Betätiger 4 besitzt auf seiner dem Riegel 16 abgekehrten Seite eine seitlich schräge Rastnut 29, vgl.
Der Betätiger 4 besitzt auf seiner dem Riegel 16 abgekehrten Seite eine Ausnehmung zur Aufnahme eines Auslöseelementes 31, das mit einem korrespondierenden Ansprechelement 32 zusammenwirkt. Bei dem Auslöseelement 31 kann es sich beispielsweise um einen Magneten und bei dem Ansprechelement 32 um einen Reedschalter handeln, es kann sich aber auch bei dem Auslöseelement 31 um einen Schwingkreis oder einen TAG und bei dem Ansprechelement 32 um eine Spule mit Auswertekreis bzw. einen für einen TAG geeigneten Anregungs- und Auswertekreis handeln. Hierdurch wird überprüft, ob der Betätiger 4 und gegebenenfalls der richtige Betätiger 4 in das Gehäuse 8 der Zuhalteeinheit 2 eingeführt ist, und ein entsprechendes elektrisches Signal erzeugt.The
Das Ansprechelement 32 ist groß genug zu wählen, so daß es das Auslöseelement 31 immer sicher erfassen kann.The
Wenn die Zuhalteeinheit 2 sowohl für eine rechte wie auch eine linke Betätigungseinheit 1 verwendbar sein soll, wird das Ansprechelement 32 zweimal vorgesehen.If the locking unit 2 is to be usable for both right and left operating unit 1, the
Zusätzlich ist es wünschenswert, die Stellung des Riegels 16 mittels einer entsprechenden Sensoreinrichtung 33 zu überwachen. Diese wird im dargestellten Ausführungsbeispiel durch eine Gabellichtschrankenanordnung gebildet, die wenigstens eine wie dargestellt oder zwei parallel zueinander in den Gehäuse 8 fest angeordnete Gabellichtschranken 34 umfaßt, während die Ankerstange 13 drehfest damit verbunden ein Paddel 35 trägt, das sich mit der Ankerstange 13 in der entsprechenden Spalte der Gabellichtschranke 34 bewegt und für jede Gabellichtschranke 34 eine Lichtdurchtrittsöffnung aufweist. Nur wenn der Riegel 16 in den Betätiger 4 eingefallen ist, wird die Lichtdurchtrittsöffnung durchstrahlt und es wird ein entsprechendes Signal abgegeben.In addition, it is desirable to monitor the position of the
Außerdem können zur Überwachung des Vorhandenseins der Betätigereinheit 1 und damit der Absperreinrichtung in der geschlossenen Stellung am Gehäuse 3 der Betätigereinheit 1 ein Auslöseelement (nicht sichtbar) und im Gehäuse 8 der Zuhalteeinheit 2 ein genügend großes Ansprechelement 36 (letzteres vorzugsweise auf der rechten und der linken Seite) vorgesehen sein. Diese können wie die Elemente 31, 32 ausgebildet sein. Dies dient zur zusätzlichen Absicherung und zum Identifizieren, ob die Absperreinrichtung noch offen oder geschlossen ist.In addition, to monitor the presence of the actuator unit 1 and thus the shut-off device in the closed position on the
Der Einsatz 19 bildet einen Kanal mit einem Querschnitt entsprechend der Form der Schlitze 11 zum Einschieben des Betätigers 4 und besitzt eine offene Rückseite, so daß das Rastelement 30 mit dem Betätiger 4 in Eingriff gelangen kann, und gegenüber eine Ausnehmung 19a für den Riegel 16, begrenzt von zwei Seitenwandungen 19b, sowie bodenseitig eine Öffnung 19c für den Durchtritt der Ankerstange 13.The
Die dem Deckel 10 des Gehäuses 8 gegenüberliegende Wandung kann als Leiterplatte ausgebildet sein und die Ansprechelemente 32, die Gabellichtschranken 34, eine Anschlußklemme für ein durch eine bodenseitige Öffnung zugeführtes elektrisches Kabel etc. tragen.The
Das Gehäuse 8 ist zweckmäßigerweise unten nach hinten abgeschrägt, wobei der durch die Abschrägung begrenzte Gehäuseabschnitt einerseits gegenüber dem übrigen Gehäuseinneren durch eine Zwischenwand 39 abgetrennt und andererseits von einem zusätzlichen in Seitenansicht dreieckigen Deckel 40 verschließbar ist, so daß das verschlossene Gehäuse 8 insgesamt quaderförmig ist.
