Abstract

The object of the invention is to provide an electrically controlled door lock which can be reliably manipulated and easily retrofitted and which supplements a mechanical mortise lock to form a controlled lock. This object is achieved by providing, on the outside of the door, a fitting which covers the door-handle nut and encloses the locking cylinder and in which an electromagnetic lock coupling is accommodated. This coupling connects the lock nut to a handle which is actuated after feeding in the opening pulse and withdraws the latch. <IMAGE>

Description

Technisches GebietTechnical field

Die Erfindung betrifft ein elektrisch ansteuerbares Türschloß mit einem üblichen Einsteckschloß, das außer einem Schließzylinder und dem hierdurch betätigten Riegel eine über einen Wechsel zurückziehbare Falle aufweist und das auf der Türaußenseite einen die Schloßnuß verdeckenden Beschlag trägt, in dem eine elektromagnetische Schloßkupplung untergebracht ist, die die Schloßnuß beim Anlegen eines Öffnungsimpulses mit einer Handhabe verbindet, damit die Falle über die Handhabe zurückgezogen werden kann.The invention relates to an electrically controllable door lock with a conventional mortise lock which, in addition to a lock cylinder and the bolt actuated thereby, has a latch which can be retracted via a change and which on the outside of the door carries a fitting which conceals the lock nut and in which an electromagnetic lock coupling is accommodated which Connects the lock nut with a handle when applying an opening impulse so that the latch can be pulled back over the handle.

Stand der TechnikState of the art

Ein elektrisch angesteuertes Schloß wird in dem Patent DE 36 43 388 beschrieben. Es behandelt ein Einstecktürschloß mit sicherheitsschloßbetätigtem Hauptriegel und einer alternativ über Wechsel oder Klinke bewegten Falle, wobei die Bewegung der Schloßnuß und der Falle durch einen abfragbaren Elektromagneten gesteuert ist. Der Elektromagnet und der Steuermechanismus sind in das Gehäuse des Einsteckschlosses integriert. Alle weiteren Bestandteile wie Steuerung, Tastatur und Stromversorgung müssen außerhalb untergebracht werden.An electrically controlled lock is described in the patent DE 36 43 388. It deals with a mortise lock with a main lock operated by a safety lock and an alternate latch or latch, the movement of the lock nut and latch being controlled by a solenoid that can be queried. The electromagnet and the control mechanism are integrated in the housing of the mortise lock. All other components such as control, keyboard and power supply must be housed outside.

Wenn Büros, Hotels oder Haustüren mit diesem Schloß ausgestattet werden sollen, muß in die Tür nicht nur das neuartige Einsteckschloß eingebaut werden, sondern es muß auch eine nicht manipulierbare Kabelverbindung mit einem außenliegenden Tastaturbeschlag und Versorgungsteil hergestellt werden. Hierdurch wird die Nachrüstung von Anlagen mit diesem Schloß erschwert.If offices, hotels or front doors are to be equipped with this lock, not only the new mortise lock must be installed in the door, but also a non-manipulable cable connection with an external keyboard fitting and supply part must be made. This makes it difficult to retrofit systems with this lock.

Aus der PCT-Anmeldung WO 90/01603 ist ein elektrisch ansteuerbares Türschloß bekannt geworden, das zusätzlich einen normalen Sicherheitsschließzylinder aufweist. Das elektrisch gesteuerte Schloß ist in einem aufgesetzten Gehäuse mit Tastatur untergebracht, die über eine Logik eine elektromagnetische Schloßkupplung ansteuert. Beim Anlegen eines Öffnungsimpulses wird kurzfristig die Schloßnuß mit einer Handhabe verbunden, so daß man die Schloßfalle mit der Handhabe zurückziehen kann.From PCT application WO 90/01603 an electrically controllable door lock has become known, which additionally has a normal security lock cylinder. The electrically controlled lock is housed in an attached housing with a keyboard that controls an electromagnetic lock coupling via logic. When an opening impulse is applied, the lock nut is briefly connected to a handle so that the lock latch can be pulled back with the handle.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, ein ansteuerbares Türschloß zu schaffen, das ohne Ausbau des vorhandenen Einsteckschlosses nachrüstbar ist und sich durch einen besonders kleinen und stromsparenden Elektromagneten auszeichnet.The invention has for its object to provide a controllable door lock that can be retrofitted without removing the existing mortise lock and is characterized by a particularly small and energy-saving electromagnet.

Diese Aufgabe wird mit den im Kennzeichen des Anspruches 1 angegebenen Mitteln gelöst.This object is achieved with the means specified in the characterizing part of claim 1.

In Fig. 1 ist mit 1 der Beschlag bezeichnet, der als flache Wanne ausgebildet ist und vorzugsweise aus Leichtmetallguß besteht. In eine Aussparung 1a ist von hinten eine Tastatur 2 eingesetzt, die Drucktasten für die Ziffern 0 - 9, den Einschaltknopf "ON" und den Programmierschalter "P" aufweist. Eine Leuchtdiode 3 zeigt durch Blinklicht die Öffnungsbereitschaft an. Außerdem werden die Eingabekontakte und das Ende der Öffnungsbereitschaft akustisch signalisiert.In Fig. 1, the fitting 1 is designated, which is designed as a flat trough and preferably consists of light metal casting. A keyboard 2, which has pushbuttons for the digits 0 - 9, the switch "ON" and the programming switch "P", is inserted into a recess 1a from the rear. A light emitting diode 3 indicates the readiness for opening by blinking light. In addition, the input contacts and the end of the readiness to open are signaled acoustically.

Unterhalb der Tastatur 2 ist eine Aussparung 1b zur Aufnahme des Schließzylinders vorgesehen. In der Mitte rechts ist eine Handhabe 4 gelagert, die über einen Vierkant in die Schloßkupplung eingreift.A recess 1b is provided below the keyboard 2 for receiving the locking cylinder. In the center right is a handle 4 which engages with a square in the lock coupling.

In Fig. 2 ist auf der Rückseite des Beschlages 1 die Schloßkupplung 5 zu sehen, die mit vier Schrauben 6 befestigt ist. Die Kupplung wird über den Vierkant 4a der Handhabe 4 betätigt. Oben rechts ist die Tastatur 2 angeordnet, oben links die Steuereinheit 7. Dazwischen liegt ein Mikroschalter 8. Mit 9 ist ein Batteriesatz bezeichnet, der aus vier Monozellen oder einer Lithiumbatterie bestehen kann. Daneben ist die Aussparung 1b für den Schließzylinder angeordnet, Der verstärkte Rand 1c schützt die Steuerung vor manipulierenden Eingriffen. Der gesamte Beschlag 1 wird mit Hilfe von Schrauben von der Türinnenseite aus befestigt. Hierzu werden von außen nicht lokalisierbare Gewindesacklöcher 10 - 15 benutzt. Bei der Montage dringt ein Vierkant 16 in die Nuß 39 des Türschlosses ein, so daß das zum Öffnen erforderliche Drehmoment von der Handhabe 4 auf die Schloßfalle übertragen werden kann.In Fig. 2 on the back of the fitting 1, the lock coupling 5 can be seen, which is fastened with four screws 6. The clutch is actuated via the square 4a of the handle 4. The keyboard 2 is arranged at the top right, above on the left is the control unit 7. Between them is a microswitch 8. 9 denotes a battery pack that can consist of four mono cells or a lithium battery. In addition, the recess 1b for the locking cylinder is arranged. The reinforced edge 1c protects the control from manipulating interventions. The entire fitting 1 is fastened with screws from the inside of the door. Threaded blind holes 10 - 15 that cannot be located from the outside are used for this. During assembly, a square 16 penetrates into the nut 39 of the door lock so that the torque required for opening can be transmitted from the handle 4 to the lock latch.

Wenn man ein sogenanntes Panikschloß mit geteilter Nuß verwendet, kann die Falle jederzeit von innen entriegelt werden, während von außen nur Berechtigte Zugang haben, die die Kombination kennen. Davon unabhängig kann der Besitzer des Sicherheitsschlüssels die Falle über den Wechsel betätigen oder beispielsweise außerhalb der Dienststunden den Hauptriegel betätigen, also die Zugangsberechtigung zeitlich begrenzen.If you use a so-called panic lock with a split nut, the latch can be unlocked from the inside at any time, while only authorized persons who know the combination can access it from the outside. Regardless of this, the owner of the security key can actuate the trap via the change or, for example, actuate the main bolt outside of office hours, i.e. limit the time of access authorization.

In Fig. 3 ist die elektromagnetische Schloßkupplung 5 in Draufsicht dargestellt. Man erkennt die Grundplatte 5a und die Deckelplatte 5b, die durch Schrauben 17, 18 und verdeckte Abstandsbolzen miteinander verbunden sind. In Aussparungen der Decke sind ein Elektromagnet 19 und ein Tourstift 20 sichtbar. Ein Schaltschieber ist mit 21 bezeichnet.In Fig. 3 the electromagnetic lock coupling 5 is shown in plan view. The base plate 5a and the cover plate 5b can be seen, which are connected to one another by screws 17, 18 and hidden spacer bolts. An electromagnet 19 and a tour pin 20 are visible in recesses in the ceiling. A slide switch is designated by 21.

Fig. 4 zeigt über der Grundplatte 5a eine Zwischendecke 22, darüber einen Steuerschieber 23 und darauf einen Sperrhebel 24 mit dem Steuerhebel 25. Der Sperrhebel 24 trägt den Anker 26. Ein Schaltschieber 27 wird mit Langlöchern in den Stehbolzen 37, 38geführt. Er wird durch einen Stift 27 betätigt. Der Steuerschieber 23 ist mit einem Tourstift 20 vernietet, der in das Maul des Steuerhebels 25 hineinragt. Aufbau und Funktion der aus den Teilen 19, 20 und 23 - 26 bestehenden elektromagnetischen Sperreinrichtung sind aus der EP 0228027 B 1, insbesondere Fig. 9 und 10, bekannt.4 shows an intermediate ceiling 22 above the base plate 5a, a control slide 23 above it and a locking lever 24 with the control lever 25 thereon. The locking lever 24 carries the armature 26. A slide switch 27 is guided with elongated holes in the stud bolts 37, 38. It is operated by a pin 27. The control slide 23 is riveted to a tour pin 20 which projects into the mouth of the control lever 25. The structure and function of the electromagnetic blocking device consisting of parts 19, 20 and 23-26 are known from EP 0228027 B1, in particular FIGS. 9 and 10.

Fig. 5 zeigt die Grundplatte 5a, die darüber liegende Zwischendecke 22 und den darauf gelagerten Steuerschieber 23 mit dem Tourstift 20. Der Steuerschieber 23 wird über ein quergestelltes Langloch 23a durch einen Steuerdorn 28 angetrieben, der durch eine Aussparung 22a der Zwischendecke 22 hindurchgreift.5 shows the base plate 5a, the intermediate ceiling 22 lying thereon and the control slide 23 mounted thereon with the tour pin 20. The control slide 23 is driven via a transverse elongated hole 23a by a control mandrel 28 which extends through a cutout 22a in the intermediate ceiling 22.

Fig. 6 stellt die Grundplatte 5a mit drei drehbar gelagerten Kupplungsscheiben dar. Rechts ist die Steuerscheibe 29 angeordnet, die den Steuerdorn 28 trägt. Sie wird bewegt durch die Mittelscheibe 30, die durch eine Zugfeder 31 mit ihrer Nase 30a gegen einen Nocken 29a der Steuerscheibe 29 gezogen wird. Mit 32 ist eine Antriebsscheibe bezeichnet, die über einen Vierkant 16 mit der unter Federspannung stehenden Nuß 39 des Einsteckschlosses verbunden wird. Alle drei Scheiben sind durch Aussparungen und auf der Grundplatte 5a befestigte Anschläge 33, 34, 35 nur begrenzt verdrehbar. Im gezeichneten Ruhezustand ist ein Leerlauf zwischen der Mittelscheibe 30 und der Antriebsscheibe 32 sichtbar. Wenn jetzt zur Abfrage des Sperrzustandes die Steuerscheibe 29 über die Handhabe 4 verdreht wird, bewegt sich zuerst der Steuerschieber 23 mit dem Tourstift 20 im Maul des Steuerhebels 25. Zugleich drückt ein Stift 36 auf dem Steuerschieber 23 bei stromlosem Magneten 19 den Anker 26 hoch. Der Tourstift 20 läuft gegen die Sperrnase des Steuerhebels 25.6 shows the base plate 5a with three rotatably mounted clutch disks. The control disk 29, which carries the control mandrel 28, is arranged on the right. It is moved by the center disk 30, which is pulled by a tension spring 31 with its nose 30a against a cam 29a of the control disk 29. With 32 a drive pulley is designated, which is connected via a square 16 to the spring-loaded nut 39 of the mortise lock. All three disks can only be rotated to a limited extent by recesses and stops 33, 34, 35 fastened on the base plate 5a. In the idle state shown, idling between the center disk 30 and the drive disk 32 is visible. If the control disk 29 is now rotated via the handle 4 to query the locked state, the control slide 23 first moves with the tour pin 20 in the mouth of the control lever 25. At the same time, a pin 36 on the control slide 23 presses the armature 26 up when the magnet 19 is de-energized. The tour pin 20 runs against the locking lug of the control lever 25.

Dieser Vorlaufweg zur Abtastung des Sperrzustandes erfolgt ohne jeden Eingriff auf die Antriebsscheibe 32. Somit ist die Falle des Einsteckschlosses auch durch hohe Beschleunigung an der Handhabe 4 nicht manipulierbar.This advance path for scanning the locked state takes place without any intervention on the drive disk 32. Thus, the latch of the mortise lock cannot be manipulated even by high acceleration on the handle 4.

Wenn aber der Elektromagnet 19 nach dem Eintasten der Geheimzahl erregt ist und der Anker 26 festgehalten wird, drückt der Stift 36 mit dem Sperrhebel 24 auch den Steuerhebel 25 hoch. Damit ist der Weg für den Tourstift frei und die Mittelscheibe 30 kann die Antriebsscheibe mitnehmen. Beim Anliegen des Öffnerimpulses kann somit die Falle über die Handhabe 4 zurückgezogen werden.However, if the electromagnet 19 is energized after the keying in of the secret number and the armature 26 is held in place, the pin 36 also presses the control lever 25 up with the locking lever 24. This clears the way for the tour pin and the center disk 30 can take the drive disk with it. When the opening pulse is applied, the trap can thus be withdrawn via the handle 4.

Für den äußerst geringen Stromverbrauch ist es entscheidend, daß der Magnet keinerlei Hubarbeit zu leisten braucht, sondern daß er lediglich den angelegten Anker festhält, während der Steuerhebel und der Sperrhebel um das Ankerlager als Drehpunkt geschwenkt werden. Die Hubarbeit zur Abfrage des Sperrzustandes wird allein von Hand aufgebracht.For the extremely low power consumption, it is crucial that the magnet does not have to do any lifting work, but that it only holds the attached armature, while the control lever and the locking lever are pivoted around the armature bearing as a fulcrum. The lifting work to query the locked state is done by hand alone.

Die Steuereinrichtung erfordert keinerlei Verdrahtung, so daß zur Montage lediglich einige Bohrlöcher für die Befestigungsschrauben anzubringen sind. Zur sicheren Befestigung des äußeren Beschlages und aus gestalterischen Gründen ist es zweckmäßig, einen gleichgroßen inneren Türbeschlag vorzusehen, der außer den Schraubenlöchern lediglich eine Öffnung für eine übliche Türklinke und einen Durchbruch für den Sicherheitszylinder aufweist.The control device does not require any wiring, so that only a few drill holes for the fastening screws have to be made for assembly. For secure fastening of the outer fitting and for design reasons, it is expedient to provide an inner door fitting of the same size which, apart from the screw holes, only has an opening for a conventional door handle and an opening for the security cylinder.

Der Wartungsaufwand für das neue steuerbare Schloß ist äußerst gering, weil bei Verwendung einer Lithium-Batterie ein Betrieb für 4 - 6 Jahre gewährleistet ist.The maintenance work for the new controllable lock is extremely low because operation with a lithium battery is guaranteed for 4-6 years.

Der Schaltschieber 21 betätigt den Mikroschalter 8, der in der Steuereinheit 7 die Programmierung aktiviert. Damit wird sichergestellt, daß eine neue Geheimzahl nur eingegeben werden kann, wenn der Steuerschieber 23 zurückgezogen und somit das Schloß entsperrt ist.The slide switch 21 actuates the microswitch 8, which activates the programming in the control unit 7. This ensures that a new PIN can only be entered when the control slide 23 is withdrawn and the lock is unlocked.

Bei der Anordnung nach Fig. 1 und 2 ist die Schloßkupplung 5 quer eingebaut. Die Zylinderschloßaussparung 1b, die Handhabe 4 mit dem Vierkant 16 und die mit unterbrochenen Linien angedeutete Schloßnuß des Einsteckschlosses bilden ein Dreieck.In the arrangement according to FIGS. 1 and 2, the lock coupling 5 is installed transversely. The cylinder lock recess 1b, the handle 4 with the square 16 and the lock nut of the mortise lock indicated by broken lines form a triangle.

Es ist aber auch möglich, die genannten Teile übereinander auf einer Linie anzuordnen.
Ein derartiger Beschlag ist in Fig. 7 und 8 dargestellt.
However, it is also possible to arrange the parts mentioned above one another on a line.
Such a fitting is shown in FIGS. 7 and 8.

Fig. 7 zeigt den langgestreckten Beschlag 40 von außen. Unten ist wiederum die Zylinderschloßaussparung 1b angeordnet. Darüber liegt die nicht sichtbare Schloßnuß 39 und darüber eine ovale Handhabe 43. Den oberen Abschluß bildet ein integrierter Kartenleser 41.Fig. 7 shows the elongated fitting 40 from the outside. The cylinder lock recess 1b is again arranged at the bottom. Above it is the invisible lock nut 39 and an oval handle 43 above it. An integrated card reader 41 forms the upper end.

In der Rückansicht nach Fig, 8 erkennt man außer der Aussparung 1b die um 90° gedrehte Schloßkupplung 5, das Batteriefach 42 und den Kartenleser 41.In the rear view according to FIG. 8, in addition to the recess 1b, the lock coupling 5 rotated by 90 °, the battery compartment 42 and the card reader 41 can be seen.

Die Funktion der Schloßkupplung 5 und ihrer Einzelteile entspricht in allem der in Fig. 3 - 6 beschriebenen.The function of the lock coupling 5 and its individual parts corresponds in all to that described in FIGS. 3-6.

Gewerbliche VerwertbarkeitCommercial usability

Das beschriebene Türschloß ist vorwiegend für Hotelzimmertüren bestimmt.
Falls es jedoch in der einen oder anderen Ausführungsform an nicht beaufsichtigten Außentüren eingesetzt werden soll, kann es zweckmäßig sein, die elektromagnetische Schloßkupplung und die Steuerelektronik in den inneren Beschlag zu verlegen, so daß nur die Tastatur oder der Kartenleser außen angeordnet ist. Bei Anwendung des Schlosses im Hotelbereich bietet der Beschlag eine ausreichend große Freifläche, um ein Display oder beleuchtbare Schilder mit den üblichen Hinweisen für das Hotelpersonal oder Besucher unterzubringen.
The door lock described is primarily intended for hotel room doors.
However, if it is to be used in one or another embodiment on unattended external doors, it may be appropriate to move the electromagnetic lock coupling and the control electronics in the inner fitting so that only the keyboard or the card reader is arranged on the outside. When using the lock in the hotel area, the fitting offers a sufficiently large open space to accommodate a display or illuminated signs with the usual information for hotel staff or visitors.

Die beschriebene elektromagnetische Schloßkupplung kann nach entsprechender Anpassung auch als Wertfachschloß im Bankbereich eingesetzt werden. Dazu wird vorzugsweise der Freigabeimpuls für eine Falle vom Sicherheitspersonal gegeben, wobei der Bankfachmieter von Hand die Falle öffnet und anschließend mit seinem Sicherheitsschlüssel einen Hauptriegel zurückzieht, Die Falle und das Sicherheitsschloß sind dabei aber nicht durch einen Wechsel gekoppelt.

Figure imgb0001
The electromagnetic lock coupling described can also be used as a locker in the bank area after appropriate adjustment. For this purpose, the release impulse for a trap is preferably given by the security personnel, the bank tenant manually opening the trap and then withdrawing a main bolt with his security key, but the trap and the security lock are not coupled by a change.
