Abstract

The invention relates to the improvement and further development of electromagnetically controlled door locks. It is known to use as a door opener a powerful electromagnet which frees a pivotable lock plate. Lifting work requiring appreciable electrical power is needed for this. The subsequent installation of such door openers necessitates the laying of wiring and mortising work on the door frame. The object of the invention is to provide a cheap controlled lock which needs no additional installation space and which, because of an extremely low energising power, can be fed from a dry battery. In the solution, the lock follower (7) possesses additionally a control element (7b) deflecting a control lever (12) which via a weak leg spring (15) takes up a blocking lever (13) which is equipped with a magnet armature (13a) and which is located opposite a blocking nose (7c) of the lock follower. <IMAGE>

Description

Technisches GebietTechnical field

Die Erfindung betrifft ein elektrisch angesteuertes Schloß mit einer unter Federspannung stehenden Schloßnuß und frei­laufender Falle.The invention relates to an electrically controlled lock with a spring nut under lock and free-running case.

Stand der TechnikState of the art

Es ist bekannt, bei Haustüren oder sonstigen Zugangstüren im Schließblech einen Elektromagneten anzuordnen, der bei Wechselstromerregung das schwenkbare Schließblech freigibt. Die Freigabe der Tür wird durch ein schnarrendes Geräusch akustisch angezeigt. Dieser elektrische Türöffner wird über einen Klingeltransformator an das Stromnetz ange­schlossen. Der Magnet benötigt relativ viel Platz und hat einen vergleichsweise hohen Strombedarf. Eine Speisung aus einer Trockenbatterie kommt sowohl wegen der Erreger­leistung als auch wegen des benötigten Wechselstromes nicht infrage. Beim Einbau in den Türrahmen sind in jedem Falle zusätzliche Stemmarbeiten erforderlich.It is known to arrange an electromagnet in front plates or other access doors in the striking plate, which releases the pivotable striking plate in the event of AC excitation. The release of the door is indicated acoustically by a snarling sound. This electric door opener is connected to the power supply via a bell transformer. The magnet requires a relatively large amount of space and has a comparatively high power requirement. A supply from a dry battery is out of the question both because of the excitation power and because of the required alternating current. When installing in the door frame, additional chiselling work is required.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, ein preiswertes elektrisch angesteuertes Schloß zu schaffen, das keinen zusätzlichen Einbauraum benötigt, also gegen jedes Serien­schloß austauschbar ist, und eine so geringe Erreger­leistung aufweist, daß es auch aus einer Trockenbatterie gespeist werden kann.
Dabei sind alle Steuerelemente im Schloßgehäuse selbst untergebracht, so daß also das übliche Schließblech unver­ändert beibehalten kann.The invention has for its object to provide an inexpensive electrically controlled lock that does not require additional installation space, so it is interchangeable with any series lock, and has such a low excitation power that it can also be powered by a dry battery.
All controls are housed in the lock housing itself, so that the usual striking plate can remain unchanged.

Diese Aufgabe wird durch die Merkmale gemäß dem zweiten Teil des Patentanspruches 1 gelöst.This object is achieved by the features according to the second part of patent claim 1.

Beschreibung der ZeichnungenDescription of the drawings

Ein Ausführungsbeispiel der Erfindung wird anhand von Fig. 1 bis 7 der Zeichnung erläutert.

  • Fig. 1 zeigt ein Türeinsteckschloß, dessen Außendrücker elektrisch gesteuert ist und bei dem der Schloßdeckel entfernt ist. Dieses Schloß wird freigegeben, wenn der Elektromagnet erregt ist.

An embodiment of the invention is explained with reference to FIGS. 1 to 7 of the drawing.
  • Fig. 1 shows a door mortise lock, the outside handle is electrically controlled and in which the lock cover is removed. This lock is released when the electromagnet is energized.
  • Fig. 2 shows the same lock after removing some parts,
  • 3 the locking lever,

In Fig. 1 ist mit 1 die Grundplatte bezeichnet, mit 2 das Schloßschild, mit 3 die Falle, mit 4 der zum Teil darge­stellte Riegel. Die mit einem Haken 3a versehene Falle 3 ist zwischen einem Stehbolzen 5 und einem Quader 6 geführt. Mit 7 ist eine in der Grundplatte gelagerte Schloßnuß bezeichnet, deren Exzenterhebel 7a an dem Haken 3a der Falle angreift. Eine starke Spiralfeder 8 preßt über eine Schubstange 9 den Exzenterhebel 7a gegen den Quader 6. Die Falle 3 ist freilaufend gelagert und wird durch eine schwächere Fallen­feder 10 in Eingriffstellung gehalten. Ein Wechsel 11 er­möglicht es, daß die Falle 3 über den nicht dargestellten Schließzylinder (Profil 17) zurückgezogen werden kann.In Fig. 1, 1 denotes the base plate, 2 the lock shield, 3 the latch, 4 the bolt shown in part. The case 3 provided with a hook 3a is guided between a stud 5 and a cuboid 6. With 7 a lock nut mounted in the base plate is designated, the eccentric lever 7a engages the hook 3a of the case. A strong coil spring 8 presses the eccentric lever 7a against the cuboid 6 via a push rod 9. The latch 3 is freely supported and is held in the engaged position by a weaker latch spring 10. A change 11 enables the latch 3 to be withdrawn via the locking cylinder (profile 17), not shown.

Die Schloßnuß 7 ist in an sich bekannter Weise geteilt. Dies bedeutet, daß der dem Betrachter zugewandte innere Teil über eine Vierkantwelle und eine Innenklinke jederzeit betätigt werden kann, um die Tür von innen ohne weiteres öffnen zu können.The lock nut 7 is divided in a manner known per se. This means that the inner part facing the viewer can be actuated at any time via a square shaft and an inner latch in order to be able to open the door easily from the inside.

Der darunter liegende Teil der Schloßnuß kann nur über die Außenklinke betätigt werden. Dieser Teil weist außer dem Exzenterhebel 7a als Steuerelement einen Steuernocken 7b und eine Sperrnase 7c auf. Der Steuernocken 7b wirkt auf einen Steuerhebel 12 ein. Darunter liegt ein Sperrhebel 13, der der Sperrnase 7c gegenübersteht. Beide Hebel sind auf einem Stehbolzen 14 gelagert. Der Steuernocken 7b ist so ausgebil­det, daß er den Steuerhebel 12 nach links drückt, wenn der äußere Türgriff betätigt wird. Der Steuerhebel 12 nimmt über eine schwache Schenkelfeder 15 den Sperrhebel 13 mit, wenn sein Anker 13a nicht von dem Elektromagneten 16 festgehalten wird. Wenn der Elektromagnet 16 nicht erregt ist, gerät der Sperrhebel 13 unter die Sperrnase 7c der Schloßnuß 7, so daß deren Bewegung nach einem kurzen Anlaufweg abgebremst wird. Bei erregtem Magneten 16 bleibt der Sperrhebel 13 in Ruhe­lage und die Sperrnase 7c läuft an dem Sperrhebel 13 vorbei.The part of the lock nut underneath can only be operated via the external jack. In addition to the eccentric lever 7a, this part has a control cam 7b and a locking lug 7c as a control element. The control cam 7b acts on a control lever 12. Below this is a locking lever 13 which faces the locking lug 7c. Both levers are mounted on a stud 14. The control cam 7b is designed so that it pushes the control lever 12 to the left when the outer door handle is operated. The control lever 12 takes the locking lever 13 with it via a weak leg spring 15 when its armature 13a is not held by the electromagnet 16. When the electromagnet 16 is not energized, the locking lever 13 gets under the locking lug 7c of the lock nut 7, so that its movement is slowed down after a short start-up distance. When the magnet 16 is energized, the locking lever 13 remains in the rest position and the locking lug 7c runs past the locking lever 13.

Mit 23 ist eine Drahtfeder bezeichnet, deren oberes Ende an einem Stift 24 anliegt, während das untere Ende um einen Bolzen 25 gelegt ist. Der mittlere Teil der Feder ist so um den Stehbolzen 14 geschlungen, daß sie über den Stift 24 den Steuerhebel 12 nach rechts bewegt. Beim Herunterdrücken der Außenklinke wird dieser Hebel unter Verformung der Draht­feder 23 nach links geschwenkt.23 with a wire spring is designated, the upper end of which rests on a pin 24, while the lower end is placed around a bolt 25. The middle part of the spring is wrapped around the stud 14 so that it moves the control lever 12 to the right via the pin 24. When the outer pawl is pressed down, this lever is pivoted to the left while deforming the wire spring 23.

Die Schloßgrundplatte 1 (und auch der nicht dargestellte Deckel) sind an genormten Stellen mit Durchbrüchen 18, 19, 20, 21, 22 versehen, durch die Befestigungsschrauben für die Schloßschilder oder sonstige Beschläge hindurchgesteckt werden können. Alle Funktionsteile des Schlosses, insbeson­dere die Schloßnuß mit ihren Vorsprüngen, sind so ausgebil­det und angeordnet, daß die Funktionen bei durchgesteckten Schrauben nicht behindert werden.The lock base plate 1 (and also the cover, not shown) are provided at standard locations with openings 18, 19, 20, 21, 22 through which fastening screws for the lock shields or other fittings can be inserted. All functional parts of the lock, in particular the lock nut with its projections, are designed and arranged so that the functions are not hindered when the screws are inserted.

In Fig. 2 ist das Schloß nach Fig. 1 in einem anderen Funktionszustand dargestellt. Der Hebel 13 wurde bei strom­losem Magneten 16 von dem nicht dargestellten Steuerhebel 12 mitgenommen, wobei die Drehung entgegen dem Uhrzeigersinn durch eine Rechtsdrehung der Schloßnuß 7 bewirkt wird. In dieser Stellung des Hebels 13 stößt die Sperrnase 7c beim Herabdrücken der Außenklinke gegen das hochgebogene Ende 13b des Sperrhebels 13. Dieser Hebel ist insgesamt stark genug ausgebildet, um das auf die Außenklinke ausgeübte maximale Drehmoment aufzufangen.In Fig. 2 the lock of Fig. 1 is shown in a different functional state. The lever 13 was taken away from the control lever 12, which is not shown, when the magnet 16 was deenergized, the counterclockwise rotation being effected by a clockwise rotation of the lock nut 7. In In this position of the lever 13, the locking lug 7c pushes against the bent-up end 13b of the locking lever 13 when the outer pawl is pressed down. This lever is overall strong enough to absorb the maximum torque exerted on the outer pawl.

In Fig. 3 ist der Sperrhebel 13 mit dem Magnetanker 13a und dem hochgebogenen Ende 13b dargestellt. Ein Bolzen 18 dient als Anschlag für die Schenkelfeder 15, deren zweiter Schen­kel von dem in Fig. 4 dargestellten Steuerhebel 12 mitgenom­men wird. Der Steuerhebel ist im Bereich der Linien 12a, 12b abgekröpft, damit sein Mittelteil nicht mit dem Anker 13a und dem Elektromagneten 16 kollidiert.In Fig. 3, the locking lever 13 is shown with the magnet armature 13a and the bent end 13b. A bolt 18 serves as a stop for the leg spring 15, the second leg of which is carried by the control lever 12 shown in FIG. 4. The control lever is bent in the area of the lines 12a, 12b so that its central part does not collide with the armature 13a and the electromagnet 16.

Das Schloß nach Fig. 5 stimmt in sehr vielen Einzelteilen mit dem bisher beschriebenen überein. Lediglich die Schloßnuß, der Steuerhebel und der Sperrhebel sind abweichend ausgebil­det. Die Schloßnuß 7 weist als Steuerelement einen Steuer­stift 7d auf, der den strichpunktiert angedeuteten Steuer­hebel 26 im Uhrzeigersinn verschwenkt. Der Steuerhebel nimmt den in seiner rechten Endlage gezeichneten Sperrhebel 27 mit, wenn der Magnet 16 stromlos ist.
Wenn aber der Anker 27a des Sperrhebels 27 vom Elektromagne­ten 16 festgehalten wird, läuft die Sperrnase 7e der Nuß 7 auf den Sperrhebel 27 auf, so daß das bestromte Schloß blockiert ist.
In der Ruhelage liegt der Anker 27a des Sperrhebels 27 - abweichend von der Zeichnung - am Elektromagneten 16 an. Beim Herabdrücken der Außenklinke drückt zunächst der Stift 7d den Steuerhebel 26 nach außen, wobei dieser über die Feder 15 auf den Sperrhebel 27 ein Moment ausübt. Bei bestromtem Magnet 16 bleibt der Hebel 27 in Sperrstellung, bei Stromunter­brechung wird das Schloß freigegeben. Der Elektromagnet 16 braucht keinerlei Hubarbeit zu leisten, sondern den anliegen­den Anker nur festzuhalten.5 corresponds in very many individual parts to that described so far. Only the lock nut, the control lever and the locking lever are designed differently. The lock nut 7 has a control pin 7d as a control element, which pivots the control lever 26 indicated by dash-dotted lines in a clockwise direction. The control lever takes the locking lever 27 drawn in its right end position when the magnet 16 is de-energized.
However, when the armature 27a of the locking lever 27 is held by the electromagnet 16, the locking lug 7e of the nut 7 runs onto the locking lever 27, so that the energized lock is blocked.
In the rest position, the armature 27a of the locking lever 27 - deviating from the drawing - bears against the electromagnet 16. When the outer pawl is pressed down, the pin 7d first presses the control lever 26 outwards, which exerts a moment on the locking lever 27 via the spring 15. When the magnet 16 is energized, the lever 27 remains in the blocking position, and the lock is released when the power is interrupted. The electromagnet 16 does not have to do any lifting work, but only has to hold the attached armature.

In Fig. 6 ist der Sperrhebel 27 mit dem Magnetanker 27a dar­gestellt.6, the locking lever 27 is shown with the magnet armature 27a.

Fig. 7 zeigt den Steuerhebel 26 mit der Steuerkurve 26a. An einem Stift 26b ist eine Schraubenfeder 28 aufgehängt, deren linkes Ende an dem Stift 29 (Fig. 5) angreift. Die Feder 28 zieht den Steuerhebel 26 gegen den Steuerstift 7d. Zur Rückholung des Sperrhebels 27 in die Ruhelage dient ein auf der Rückseite des Steuerhebels 26 angebrachter Stift 30, der in die Vertiefung 27b des Sperrhebels 27 eingreift.7 shows the control lever 26 with the control cam 26a. A coil spring 28 is suspended from a pin 26b, the left end of which engages with the pin 29 (FIG. 5). The spring 28 pulls the control lever 26 against the control pin 7d. A pin 30, which is attached to the rear of the control lever 26 and which engages in the recess 27b of the locking lever 27, is used to bring the locking lever 27 back into the rest position.

Wegen des außerordentlich geringen Stromverbrauches kann der Elektromagnet 16 ohne weiteres im Dauerbetrieb bestromt werden. In dieser Bauform ist das Schloß hervorragend für Paniktüren geeignet, die jederzeit von innen zu öffnen sind, aber nur im Katastrophenfall von außen her zugänglich sein müssen. Die sicherste Art, den Zugang von außen zu gewähr­leisten, besteht darin, dies durch Unterbrechung eines Stromkreises zu bewirken. Wenn nämlich durch einen Unglücks­fall die Spannungsquelle ausfällt oder die Stromleitung un­terbrochen wird, kann das Rettungspersonal von außen her ohne weiteres eindringen. Der Ruhestrombetrieb gewährleistet also ein höheres Maß an Sicherheit als der Arbeitsstromkreis. Mit anderen Worten: Es ist viel einfacher und sicherer, einen Strom zu unterbrechen, als ihn unter gewissen Stör­fallbedingungen zum Fließen zu bringen.Because of the extremely low power consumption, the electromagnet 16 can easily be energized in continuous operation. In this design, the lock is ideal for panic doors that can be opened from the inside at any time, but only need to be accessible from the outside in the event of a disaster. The safest way to ensure outside access is to do so by breaking an electrical circuit. If the voltage source fails or the power line is interrupted due to an accident, the rescue personnel can easily penetrate from the outside. Quiescent current operation thus guarantees a higher level of safety than the working circuit. In other words, it is much easier and safer to interrupt a current than to make it flow under certain accident conditions.

Beide Schloßvarianten sind zusätzlich durch den normalen Riegel und einen Schließzylinder absperrbar. Die elektrische Ansteuerung der Falle setzt natürlich voraus, daß der Riegel nicht ausgefahren ist.Both lock variants can also be locked with the normal bolt and a locking cylinder. The electrical control of the latch naturally requires that the bolt is not extended.

Wenn das Schloß zusätzlich - wie beschrieben - mit einem Wechsel ausgerüstet ist, kann die mit Freilauf versehene Falle auch über das Zylinderschloß zurückgezogen werden, ohne daß die elektrische Ansteuerung benutzt wird. Die Öffnung mit Hilfe von Schlüssel und Wechsel kann auch als Notöffnungs­maßnahme angesehen werden.If the lock is additionally - as described - equipped with a change, the free-running latch can also be withdrawn via the cylinder lock without the electrical control being used. Opening with the help of a key and change can also be seen as an emergency opening measure.

Das Schloß nach Fig. 1 und 2 sowie das Panik-Schloß nach Fig. 5 ist ohne Benutzung eines Wechsels nur mit dem Schlüssel entsperrbar, wenn man mit dem Steuernocken des Schließ­zylinders gegen den Sperrhebel 13 bzw. 27 drückt und zugleich die Außenklinke betätigt. Wenn man den Sperrhebel 13 mit dem Nocken des Schließzylinders gegen den Elektromagneten 16 drückt, wird praktisch eine Bestromung simuliert. Drückt man den Anker 27a des Sperrhebels 27 vom Elektromagneten 16 weg, so hat dies die gleiche Wirkung wie eine Stromunterbrechung.The lock according to FIGS. 1 and 2 and the panic lock according to FIG. 5 can only be unlocked with the key without using a change if one presses with the control cam of the locking cylinder against the locking lever 13 or 27 and at the same time the outer jack operated. If you press the locking lever 13 with the cam of the locking cylinder against the electromagnet 16, an energization is practically simulated. Pressing the armature 27a of the locking lever 27 away from the electromagnet 16 has the same effect as an interruption in the current.

Gewerbliche VerwertbarkeitCommercial usability

Wegen des außerordentlich geringen Stromverbrauches ist das Schloß für batteriebetriebene Zugangskontrolleinrichtungen sehr gut geeignet. Es kann also ohne die Verlegung von Strom­versorgungsleitungen auch nachträglich installiert werden, wobei wegen der Einhaltung der Normabmessungen weder im Tür­stock noch im Türblatt Stemmarbeiten erforderlich werden.Because of the extremely low power consumption, the lock is very suitable for battery-operated access control devices. It can therefore also be retrofitted without laying power supply lines, and due to compliance with the standard dimensions, no chiseling work is required in the door frame or in the door leaf.

Die Signalkontaktgabe kann entweder über eine Drucktaste von innen oder eine an der Türaußenseite angebrachte Codierein­heit erfolgen.The signal contact can be made either via a push button from the inside or a coding unit attached to the outside of the door.
