Description

Die Erfindung bezieht sich auf ein Sperrelement für eine Schließvorrichtung einer Einbruchmeldeanlage mit einem drehbar gelagerten Schalt- bzw. Sperrhebel und einem Elektromagneten, sowie einer Grundplatte und Gehäuse. .The invention relates to a locking element for a locking device of an intrusion detection system with a rotatably mounted switching or locking lever and an electromagnet, and a base plate and housing. .

Für Einbruchmeldeanlagen ist es in der Regel notwendig, einen Riegel eines Schlosses zu blockieren, um im Scharfschaltezustand der Einbruchmeldezentrale das unbeabsichtigte Öffnen und die damit verbundene Alarmauslösung zu verhindern.For intrusion alarm systems, it is usually necessary to block a bolt of a lock in order to prevent the intrusion alarm center from being opened unintentionally and the associated alarm being triggered when the intrusion alarm center is armed.

Bei einem bekannten Sperrelement einer Tresortür wird mit einem Hubmagneten ein Sperrglied (Schalt- bzw. Sperrhebel) betätigt, welches das unbeabsichtigte Auf- oder Verschließen verhindert. Für diesen Zweck ist es sehr aufwendig konstruiert. Ferner hat es einen verhältnismäßig großen Schließweg, der unter bestimmten Zeitbedingungen dazu führt, daß die Sperrfunktion wegen der Trägheit des Hubmagneten nicht erfüllt wird und eine Selbsthemmung auftreten kann.In a known locking element of a safe door, a locking member (switching or locking lever) is actuated with a lifting magnet, which prevents unintentional opening or closing. For this purpose, it is very complex. Furthermore, it has a relatively large closing path which, under certain time conditions, means that the blocking function is not fulfilled due to the inertia of the solenoid and self-locking can occur.

Aufgabe der Erfindung ist es, ein Sperrelement derart zu gestalten, daß es obige Nachteile nicht aufweist, und daß es spielfrei arbeitet und mit möglichst geringer Stromaufnahme betrieben werden kann.The object of the invention is to design a locking element such that it does not have the above disadvantages, and that it works without play and can be operated with the lowest possible power consumption.

Diese Aufgabe wird mit einem eingangs beschriebenen Sperrelement mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.This object is achieved with a locking element described at the outset with the characterizing features of claim 1.

Die erfindungsgemäße Sperrmechanik arbeitet nach dem Prinzip einer Schlingfederkupplung. Beim Drehen eines Wickeldorns in Wickelrichtung wird die an einem Ende festgehaltene Schlingfeder so stark eingeschnürt, daß durch das entstehende Reibmoment ein Weiterdrehen verhindert wird. Die Schlingfeder umschließt einen geteilten Zylinder, dessen Achse Drehpunkt für den Sperrhebel ist. Das feststehende Teil bildet die Achse eines Zylinders, der auf der Grundplatte eingestellt und befestigt ist. Der bewegliche Teil des Zylinders bildet eine Buchse, die starr mit dem Sperrhebel verbunden ist. Eine Mitnehmerplatte wird von einer Feder gegen einen Anschlag gezogen.The locking mechanism according to the invention works on the principle of a wrap spring clutch. When turning a winding mandrel in the winding direction, the wrap spring held at one end is constricted so much that further friction is prevented by the resulting frictional torque. The wrap spring encloses a split cylinder, the axis of which is the fulcrum for the locking lever. The fixed part forms the axis of a cylinder, which is set and fixed on the base plate. The movable part of the cylinder forms a bush which is rigidly connected to the locking lever. A driver plate is pulled against a stop by a spring.

Ist der Haftmagnet bestromt, dann wird die Mitnehmerplatte magnetisch gehalten. Bewegt man nun den Sperrhebel zum Öffnen, d.h. in Wickelrichtung der Schlingfeder, so wird über die magnetische Verbindung die Mitnehmerplatte mitbewegt und ein Federanschlag an der Mitnehmerplatte gibt die Schlingfeder zum Einschnüren frei. Nach geringer Drehbewegung des Sperrhebels tritt die Bremswirkung ein. Die erfindungsgemäße Anordnung hat den Vorteil, daß die Bewegung des Riegels in Öffnungsrichtung ohne Selbsthemmung, also spielfrei, fortgeführt werden kann, wenn der Haftmagnet stromlos wird. Ebenso ist eine Scharfschaltung vor dem Schließen ohne mechanische Behinderung möglich, da die Sperrwirkung nur im Wickelsinn der Schlingfeder eintritt.If the holding magnet is energized, the driver plate is held magnetically. Now move the locking lever to open, i.e. in the winding direction of the wrap spring, the driver plate is moved along via the magnetic connection and a spring stop on the driver plate releases the wrap spring for constriction. The braking effect occurs after a slight rotation of the locking lever. The arrangement according to the invention has the advantage that the movement of the bolt in the opening direction can be continued without self-locking, that is to say without play, when the holding magnet is de-energized. Arming before closing is also possible without mechanical hindrance, since the locking effect only occurs in the winding direction of the wrap spring.

In einer zweckmäßigen Ausgestaltung der Erfindung ist am Sperrhebel eine Federkraft angeordnet, die auf die Mitnehmerplatte einwirkt. Dabei ist in vorteilhafter Weise die Federkraft von einer Blattfeder gebildet, die über eine Kugel die Mitnehmerplatte gegen den Haftmagnet drückt, so daß kein Luftspalt entsteht, um die Magnetwirkung zu verstärken. Dabei sitzt der Haftmagnet auf dem Sperrhebel. Dazu ist der Sperrhebel U-förmig ausgebildet, wobei auf der Innenseite des einen Schenkels der Haftmagnet befestigt ist und die Mitnehmerplatte zwischen dem anderen Schenkel und dem Haftmagneten angeordnet ist. Ein Federanschlag an der Mitnehmerplatte verhindert im stromlosen Zustand die Einschnürung der Schlingfeder. Ein Mikroschalter signalisiert in an sich bekannter Weise die Lage des Sperrhebels im geschlossenen Zustand.In an expedient embodiment of the invention, a spring force is arranged on the locking lever, which acts on the driver plate. In this case, the spring force is advantageously formed by a leaf spring which presses the driver plate against the holding magnet via a ball, so that there is no air gap in order to increase the magnetic effect. The holding magnet sits on the locking lever. For this purpose, the locking lever is U-shaped, the holding magnet being fastened on the inside of one leg and the driver plate between the other leg and the holding magnet is arranged. A spring stop on the driver plate prevents the wrap spring from constricting when de-energized. A microswitch signals the position of the locking lever in the closed state in a manner known per se.

Über eine entsprechende Kopplung des Sperrhebels mit dem Riegel eines Schlosses bzw. mit einem Riegelgestänge eines Zahlenkombinationsschlosses kann damit ein unbeabsichtigtes Öffnen verhindert werden.A corresponding coupling of the locking lever with the bolt of a lock or with a bolt linkage of a combination lock can thus prevent accidental opening.

Die Sperrmechanik ist von einer Schlingfederkupplung gebildet, die einen auf der Grundplatte 3 feststehenden Zylinderteil 2c, einen beweglichen Zylinderteil 2b, eine Schlingfeder 1, einen drehbar gelagerten Sperrhebel 4, eine Mitnehmerplatte 5 und einen Haftmagneten 11 aufweist. Das feststehende Zylinderteil 2c ist in diesem Ausführungsbeispiel mit einem Zylinderfuß 2d auf der Grundplatte 3 justierbar und befestigbar mit einer Schraube 3a angeordnet. Dabei ist die Schlingfeder 1 mit dem einen Ende 1b im Zylinderfuß 2d fest eingespannt. An dem frei beweglichen Zylinderteil 2b ist drehbar gelagert die Mitnehmerplatte 5 mit einem Federanschlag 6 angeordnet. Darüber ist der Sperrhebel 4 fest mit dem beweglichen Zylinderteil 2b verbunden. Beide sind drehbar um die Zylinderachse 2a gelagert. Die Mitnehmerplatte 5 wird über die Zugfeder 7 an den Anschlag 8 angezogen und befindet sich damit im geschlossenen Zustand s. Über eine geeignete Vorrichtung wird ein Mikroschalter 12 betätigt.
wenn der Sperrhebel 4 ebenfalls im Schließzustand ist, was hier jedoch nicht näher dargestellt, sondern lediglich angedeutet ist. Der Haftmagnet 11 ist auf dem freien Schenkel 4a des U-förmig ausgebildeten Sperrhebels 4 fest angeordnet und zieht die Mitnehmerplatte 5 im bestromten Zustand an. Der Sperrhebel 4 weist zusätzlich eine Blattfeder 9 auf, die über eine Kugel 10 die Mitnehmerplatte 5 gegen den Haftmagnet 11 drückt, so daß sich kein Luftspalt bildet und im bestromten Zustand des Haftmagneten 11 nur geringe Kräfte notwendig sind, um eine magnetische Verbindung zwischen dem Sperrhebel 4 und der Mitnehmerplatte 5 herzustellen. Das hat den Vorteil, daß für die Sperrwirkung nur ein geringer Strom, beispielsweise 20 mA, erforderlich sind.The locking mechanism is formed by a wrap spring clutch which has a cylinder part 2c fixed on the base plate 3, a movable cylinder part 2b, a wrap spring 1, a rotatably mounted locking lever 4, a driver plate 5 and a holding magnet 11. In this exemplary embodiment, the fixed cylinder part 2c can be adjusted with a cylinder base 2d on the base plate 3 and can be fastened with a screw 3a. The wrap spring 1 is firmly clamped with one end 1b in the cylinder base 2d. The driver plate 5 with a spring stop 6 is rotatably mounted on the freely movable cylinder part 2b. In addition, the locking lever 4 is firmly connected to the movable cylinder part 2b. Both are rotatably supported about the cylinder axis 2a. The driver plate 5 is tightened via the tension spring 7 to the stop 8 and is thus in the closed state s. A microswitch 12 is actuated via a suitable device.
if the locking lever 4 is also in the closed state, which is not shown here, but is only indicated. The holding magnet 11 is fixed on the free leg 4a of the U-shaped locking lever 4 and attracts the driving plate 5 when energized. The locking lever 4 also has a leaf spring 9, which presses the driver plate 5 against the holding magnet 11 via a ball 10, so that no air gap is formed and only small forces are required in the energized state of the holding magnet 11 in order to establish a magnetic connection between the locking lever 4 and the driver plate 5. This has the advantage that only a small current, for example 20 mA, is required for the blocking effect.

Der Sperrhebel 4 weist ein Langloch 4b auf, durch das mit Hilfe einer Schraubverbindung ein Riegelgestänge mit einem Zahlenkombinationsschloß verbunden werden kann, um beispielsweise für ein Blockschloß einer Tresortür das erfindungsgemäße Sperrelement einsetzen zu können.The locking lever 4 has an elongated hole 4b through which a bolt linkage can be connected to a combination lock by means of a screw connection, for example in order to be able to use the locking element according to the invention for a block lock of a safe door.

Für den Schließ- (s) und den Öffnungs (ö) -vorgang sind nur geringe Drehbewegungen erforderlich, so daß ein sehr geringer Winkel w ausreicht, um beim unbeabsichtigten Öffnen die Sperrmechanik zu blockieren. Die Funktionsweise ist bereits oben beschrieben, sollte jedoch kurz nochmals erläutert werden. Wird der Sperrhebel 4 betätigt, d.h. der Sperrhebel um die Zylinderachse 2a gedreht, so wird die Schlingfeder 1 so stark eingeschnürt, daß durch das entstehende Reibmoment ein Weiterdrehen verhindert wird. Die Schlingfeder 1 umschließt den Zylinder, wobei im unteren Bereich zusätzlich ein Stützring 13 (nur in Fig.2 dargestellt) vorgesehen ist, um ein Aufweiten der Schlingfeder 1 zu verhindern. An dem Federanschlag 6 der Mitnehmerplatte 5 ist das freie Ende 1a der Schlingfeder 1 angeordnet, um im stromlosen Zustand eine Einschnürung der Schlingfeder 1 zu verhindern, so daß der Sperrhebel 4 frei beweglich ist, um aber im bestromten Zustand bei der Bewegung des Sperrhebels 4 und gleichzeitig der Mitnehmerplatte 5 die Schlingfeder 1 mitzunehmen, so daß die Schlingfeder 1 eingeschnürt wird und nach einer sehr geringen Drehbewegung (kleiner Winkel w) der Sperrhebel 4 gebremst wird.Only small rotary movements are required for the closing (s) and opening (ö) process, so that a very small angle w is sufficient to block the locking mechanism in the event of unintentional opening. The mode of operation has already been described above, but should be briefly explained again. If the locking lever 4 is actuated, ie the locking lever is rotated about the cylinder axis 2a, the wrap spring 1 is constricted so much that the resulting friction torque prevents further turning. The wrap spring 1 surrounds the cylinder, a support ring 13 (only shown in FIG. 2) being additionally provided in the lower region in order to prevent the wrap spring 1 from expanding. On the spring stop 6 of the driver plate 5, the free end 1a of the wrap spring 1 is arranged in order to prevent a constriction of the wrap spring 1 in the de-energized state, so that the locking lever 4 is free is movable, but in the energized state during the movement of the locking lever 4 and at the same time the driver plate 5 to take the wrap spring 1, so that the wrap spring 1 is constricted and the locking lever 4 is braked after a very slight rotary movement (small angle w).
