Description

Technisches GebietTechnical field

Die Erfindung betrifft ein elektromagnetisch gesteuertes Sperrschloß mit einem über eine Handhabe betätigten Riegel mit einem als Haltemagnet wirkenden Elektromagneten, einem mit Magnetanker versehenen Sperrhebel, einem mit dem Sperrhebel gekuppelten Steuerhebel und einem von der Handhabe betätigten Abfrageriegel, dessen Tourstift gegen einen Vorsprung des Steuerhebels fährt, wobei der Steuerhebel nur dann in die Freigabestellung kippt, wenn der Anker des Sperrhebels festgehalten ist.The invention relates to an electromagnetically controlled locking lock with a bolt operated via a handle with an electromagnet acting as a holding magnet, a locking lever provided with a magnet armature, a control lever coupled to the locking lever and an interrogation bar operated by the handle, the tour pin of which moves against a projection of the control lever. the control lever only tilts into the release position when the armature of the locking lever is held.

Stand der TechnikState of the art

Ein elektromagnetisch gesteuertes Schloß gemäß dem Oberbegriff des Anspruchs 1 mit kodierbarem Freigabebefehl und einer Handhabe zur Betätigung des Riegels ist im EP 0228027 beschrieben worden. Dieses Schloß weist einen nur Haltefunktion ausübenden Elektromagneten auf, dessen Anker auf einem Sperrhebel sitzt. Dieser Sperrhebel ist über eine Feder und einen Dorn mit einem Steuerhebel verbunden, der den Hauptriegel sperrt oder freigibt. Die Drehmomente zur Betätigung des Hauptriegels und des Sperr- und Steuerhebels werden über eine Handhabe aufgebracht, so daß der Elektromagnet nur den angebotenen Anker festzuhalten braucht. Da jede Hubarbeit entfällt, kann der für Kleinspannung ausgelegte Magnet sehr leicht und preisgünstig gehalten werden.An electromagnetically controlled lock according to the preamble of claim 1 with a codable release command and a handle for actuating the bolt has been described in EP 0228027. This lock has an electromagnet that only performs a holding function, the armature of which sits on a locking lever. This locking lever is connected via a spring and a mandrel to a control lever that locks or releases the main bolt. The torques for actuating the main bolt and the locking and control lever are applied via a handle, so that the electromagnet only needs to hold the offered anchor. Since there is no need for any lifting work, the magnet designed for low voltage can be kept very light and inexpensive.

Darstellung der ErfindungPresentation of the invention

Die Erfindung befaßt sich mit der Verbesserung derartiger Schlösser in Haltemagnettechnik. Um die Sicherheit gegen Manipulation zu erhöhen, sollen auf den Riegel während der Abfragefunktion keinerlei Verstellkräfte ausgeübt werden können. Es geht also darum, den Riegel während der Abfragebewegung der Handhabe von dieser zu entkuppeln.The invention is concerned with the improvement of such locks in holding magnet technology. In order to increase security against manipulation, no adjustment forces should be able to be exerted on the bolt during the query function. It is therefore a matter of uncoupling the bolt from the handle during the query movement.

Diese Aufgabe wird erfindungsgemäß mit den im Kennzeichen angegebenen Mitteln gelöst.This object is achieved according to the invention with the means indicated in the label.

In Fig. 1 ist mit strichpunktierten Linien das Schloßgehäuse 1 angedeutet. In ihm ist der Hauptriegel 2 verschiebbar gelagert, dessen Kopf 2a aus dem Gehäuse 1 heraustritt. In der Gehäusemitte ist eine Kupplungsscheibe 3 drehbar gelagert, die im Zentrum eine Vierkantöffnung 3a für eine Handhabe aufweist. Diese Vierkantöffnung ist zu einem Schlüsselkanal 3b erweitert, so daß man nach dem Entfernen der Handhabe einen Doppelbartschlüssel einführen kann, um ein hinter dem Schloß angeordnetes Notöffnungsschloß zu erreichen. Dieses soll dann in Funktion treten, wenn das elektromagnetisch gesteuerte Sperrschloß versagt.In Fig. 1, the lock housing 1 is indicated by dash-dotted lines. The main bolt 2 is slidably mounted in it, the head 2a of which emerges from the housing 1. In the middle of the housing, a clutch disc 3 is rotatably mounted, which has a square opening 3a in the center for a handle. This square opening is expanded to a key channel 3b, so that a double-bit key can be inserted after removal of the handle in order to reach an emergency opening lock arranged behind the lock. This should then come into operation when the electromagnetically controlled locking lock fails.

Die Kupplungsscheibe 3 trägt an ihrer Oberseite einen quaderförmigen Exzenter 3c, der in eine Mitnahmekurve 2b des Hauptriegels 2 eingreift.The clutch disc 3 carries on its upper side a cuboid eccentric 3c which engages in a driving curve 2b of the main bolt 2.

An der Unterseite der Kupplungsscheibe 3 ist ein Dorn 3d vorgesehen, der in die Steuerkurve 4a eines Abfrageriegels 4 eingreift. Dieser Riegel ist quer zur Längsachse des Gehäuses 1 verschiebbar gelagert. Er trägt an seinem oberen Rand einen Tourstift 4b, der in einen in Fig. 4 - 6 dargestellten Steuerhebel eingreift. Der Abfrageriegel weist außerdem einen Steuerstift 4c und einen Steuerschlitz 4d auf. Ein Langloch 4e dient der Führung des Riegels im Gehäuse 1.On the underside of the clutch disc 3, a mandrel 3d is provided which engages in the control curve 4a of an interrogation bolt 4. This bolt is slidably mounted transversely to the longitudinal axis of the housing 1. It bears on its upper edge a tour pin 4b which engages in a control lever shown in Figs. 4-6. The interrogation bar also has a control pin 4c and a control slot 4d. An elongated hole 4e is used to guide the bolt in the housing 1.

Die Mitnahmekurve 2b des Hauptriegels 2 besteht aus einem ersten Kreisbogen 2b1, einer Nut 2b2 und einem Kreisbogen 2b3. In der Schließlage ist der Riegel 2 durch den quaderförmigen Exzenter 3c blockiert. Wenn man die Handhabe nach rechts dreht, wandert der Exzenter 3c am Kreisbogen 2b1 entlang und über die Nut 2b2 hinweg, bis der Exzenter gegen den Kreisbogen 2b3 stößt. Auf dieser Drehbewegung von etwa 20° herrscht zwischen Riegel 2 und Kupplungsscheibe 3 Leerlauf, d.h., es wird keinerlei Kraft auf den Riegel ausgeübt. Während dieser Bewegung überträgt der Dorn 3d auf der Unterseite der Kupplungsscheibe ein Drehmoment auf den Abfrageriegel 4.The driving curve 2b of the main bolt 2 consists of a first arc 2b1, a groove 2b2 and an arc 2b3. In the closed position, the bolt 2 is blocked by the rectangular eccentric 3c. If you turn the handle to the right, the eccentric 3c moves along the arc 2b1 and over the groove 2b2 until the eccentric abuts the arc 2b3. On this rotary movement of approximately 20 °, there is no load between the bolt 2 and the clutch disc 3, i.e. no force is exerted on the bolt. During this movement, the mandrel 3d on the underside of the clutch disc transmits a torque to the interrogation bar 4.

Am Ende der Abfragebewegung nehmen die Teile 2, 3, 4 die in Fig. 2 dargestellte Position ein.At the end of the query movement, parts 2, 3, 4 assume the position shown in FIG. 2.

Im Falle der Freigabe kann die Handhabe weiter nach rechts gedreht werden, bis die Position nach Fig. 3 erreicht ist. Beim Rückzug des Riegels taucht der Exzenter 3c voll in die Nut 2b2 ein, bevor er an dem Kreisbogen 2b3 entlang gleitet. In der rechten Endstellung nach Fig. 3 ist der Riegel 2 durch den Exzenter 3c blockiert.In the event of release, the handle can be turned further to the right until the position according to FIG. 3 is reached. When the bolt is withdrawn, the eccentric 3c is fully immersed in the groove 2b2 before sliding along the circular arc 2b3. In the right end position according to FIG. 3, the bolt 2 is blocked by the eccentric 3c.

Wenn man die Handhabe nach links dreht, schiebt der Exzenter 3c den Riegel aus dem Schloßgehäuse heraus. Zugleich wird der Abfrageriegel 4 in die Ausgangslage zurückgeschoben.If you turn the handle to the left, the eccentric 3c pushes the bolt out of the lock housing. At the same time, the query bar 4 is pushed back into the starting position.

Die Wirkungsweise der elektromagnetischen Steuerung wird anhand von Fig. 4 - 6 erläutert. Auf einem gehäusefesten Dorn 5 ist ein Steuerhebel 6 gelagert, dessen als Vorsprung ausgestattete Schneide 6a dem Tourstift 4b gegenübersteht. Ein Sperrhebel 7, der einen Magnetanker 7a trägt, ist unter dem Steuerhebel 6 angeordnet, über einen Dorn 7c an dem Steuerhebel gelagert und durch eine Schraubenfeder 8 mit ihm verkuppelt. Wichtig für den Abfragevorgang ist ein gekrümmter Steuerschlitz 7b. Ein Elektromagnet 9 steht dem Anker 7a gegenüber.The mode of operation of the electromagnetic control is explained with reference to FIGS. 4-6. A control lever 6 is mounted on a mandrel 5 fixed to the housing, the cutting edge 6a of which is provided as a projection and faces the tour pin 4b. A locking lever 7, which carries a magnetic armature 7a, is arranged under the control lever 6, mounted on the control lever via a mandrel 7c and coupled to it by a coil spring 8. A curved control slot 7b is important for the interrogation process. An electromagnet 9 faces armature 7a.

Wenn der Magnet nicht erregt ist und der Abfragehebel 4 nach unten bewegt wird, drückt der Steuerstift 4c den Sperrhebel nach links. Der Anker 7a hebt ab und der Tourstift 4b stößt voll auf die Schneide 6a. Diesen Zustand zeigt Fig. 5.When the magnet is not energized and the query lever 4 is moved down, the control pin 4c pushes the lock lever to the left. The armature 7a lifts off and the tour pin 4b fully abuts the cutting edge 6a. 5 shows this state.

Wird dagegen der Magnet erregt und der Abfrageriegel 4 nach unten bewegt, wirkt der festgehaltene Magnetanker als Drehpunkt. Der Steuerstift 4c drückt den Sperrhebel 7 und mit ihm den Steuerhebel 6 nach links, wodurch der Tourstift 4b die Schneide 6a passieren kann.If, on the other hand, the magnet is excited and the interrogation bar 4 is moved downwards, the held magnet armature acts as a fulcrum. The control pin 4c presses the locking lever 7 and with it the control lever 6 to the left, as a result of which the tour pin 4b can pass the cutting edge 6a.

Um das Schloß beim Ausfall der elektromagnetischen Steuerung oder des dem Öffnungsimpuls vorgeschalteten Codiergerätes öffnen zu können, kann ein zweiter Elektromagnet eingebaut werden, der ebenfalls auf den Sperrhebel wirkt.In order to be able to open the lock in the event of failure of the electromagnetic control or of the coding device upstream of the opening pulse, a second electromagnet can be installed, which also acts on the locking lever.

Zusätzlich oder anstelle des zweiten Magneten kann unter dem beschriebenen Schloß ein Doppelbartschloß angeordnet werden. Dessen Riegel betätigt dann über einen Stift einen Schieber in dem Schloß, der mechanisch den Magnetanker in Anlageposition blockiert und damit einen Öffnungsbefehl simuliert.In addition or instead of the second magnet, a double-bit lock can be arranged under the lock described. The bolt then actuates a slide in the lock via a pin, which mechanically blocks the magnet armature in the system position and thus simulates an opening command.

An die Stelle eines Doppelbartschlosses für die Notöffnung könnte auch ein Kombinationsschloß treten.A combination lock could also replace a double-bit lock for emergency opening.

Durch die mechanische Entkupplung zwischen Handhabe und Hauptriegel während des Abfragevorganges gelingt es, mit geringen Mitteln ein Hochsicherheitsschloß mit Notöffnungseinrichtung aufzubauen.Due to the mechanical decoupling between the handle and the main bolt during the interrogation process, it is possible to set up a high-security lock with an emergency opening device with little means.

Gewerbliche VerwertbarkeitCommercial usability

Das beschriebene Sperrschloß ist hervorragend für den Serieneinsatz in allen hochwertigen Geld- und Panzerschränken geeignet, weil es preiswerter herzustellen ist als bisher bekannte Verschlüsse und zugleich eine höhere Manipuliersicherheit bietet.The lock described is ideal for series use in all high-quality wallets and armored cabinets, because it is cheaper to manufacture than previously known locks and at the same time offers greater security against manipulation.
