Description

Die Erfindung betrifft eine Schließeinrichtung mit einem in einem Gehäuse bewegbaren, zum wahlweisen Verriegeln oder Entriegeln der Schließeinrichtung vorgesehenen Kern, mit einem topfförmigen Griff zur Übertragung einer Bewegung auf den Kern und mit einer innerhalb des Griffs angeordneten Steuerelektronik zur Ansteuerung eines Sperrmechanismus, wobei der Sperrmechanismus zur Erzeugung oder Lösung eines Formschlusses zwischen dem Kern und dem Gehäuse ausgebildet ist.The invention relates to a locking device with a movable in a housing, for optional locking or unlocking the locking device provided core, with a cup-shaped handle for transmitting a movement arranged on the core and with one inside the handle Control electronics for controlling a locking mechanism, wherein the locking mechanism for generating or solving a positive connection between the core and the Housing is formed.

Solche Schließeinrichtungen werden bei heutigen Zugriffskontrollanlagen häufig eingesetzt und sind aus der Praxis bekannt. Die Steuerelektronik läßt sich bei den bekannten Schließeinrichtungen beispielsweise mit einem Code von einem Transponderchip, einem Magnetstreifen oder einer Tastatur ansteuern. Die Steuerelektronik überprüft den Code und gibt im Falle einer Zugangsberechtigung ein Schaltsignal an den Sperrmechanismus weiter. Der Sperrmechanismus hebt im Falle der Zugangsberechtigung den Formschluß zwischen dem Kern und dem Gehäuse auf, so daß der Griff zum Entriegeln der Schließeinrichtung gedreht werden kann. Die Steuerelektronik der bekannten Schließeinrichtung ist an der Innenseite des Griffs befestigt und bildet mit dem Griff eine platzsparende bauliche Einheit. Vorteile von solchen Schließeinrichtungen bestehen beispielsweise darin, daß sich die Zugangsberechtigung auf Zeitzonen begrenzen oder bei einem Verlust des Transponderchips oder des Magnetstreifens einfach sperren läßt. Such locking devices are used in today's access control systems frequently used and are out of practice known. The control electronics can be in the known Closing devices, for example, with a code of a transponder chip, a magnetic strip or a Control the keyboard. The control electronics checks the Code and enter in case of an access authorization Switching signal continues to the locking mechanism. The locking mechanism raises in the case of the access authorization the form closure between the core and the housing, so that the Handle to unlock the locking device to be rotated can. The control electronics of the known locking device is attached to the inside of the handle and forms with the handle a space-saving structural unit. Advantages of such locking devices exist, for example in that the access authorization to Limit time zones or if the transponder chip is lost or the magnetic strip.

Nachteilig bei dieser Schließeinrichtung ist, daß sich die Steuerelektronik mit dem Griff mitdreht. Dies führt bei in dem Gehäuse angeordnetem Sperrmechanismus oder bei einem feststehenden Lesegerät für den Transponder oder den Magnetstreifen dazu, daß die Übertragung von elektrischer Energie oder elektronischen Signalen zwischen dem Kern und dem Gehäuse beispielsweise Schleifkontakte oder Induktionsschleifen erfordert. Hierdurch ist die Schließeinrichtung jedoch manipulierbar und zudem störanfällig. Weiterhin gestaltet sich die Wartung der Steuerelektronik sehr aufwendig, da sie auch nach einer Entfernung des Griffs nur schwer zugänglich ist.The disadvantage of this locking device is that the control electronics with the handle rotates. this leads to when arranged in the housing locking mechanism or at a fixed reader for the transponder or the magnetic strip to the transmission of electrical Energy or electronic signals between the Core and the housing, for example, sliding contacts or Induction loops required. This is the Closing device, however, manipulated and also prone to failure. Furthermore, the maintenance of the control electronics designed very elaborate, as they are also after a distance the handle is difficult to access.

Weiterhin ist aus der DE 197 55 218 A1 ein Schließzylinder bekannt, bei dem eine Elektronik zur Steuerung einer elektromagnetischen Zuhaltung an einer unzugänglichen Stelle innerhalb des Gehäuses angeordnet ist. Daher muss zur Wartung der Elektronik der Schließzylinder vollständig demontiert werden. Dies führt jedoch zu einer sehr aufwändigen Wartung des Schließzylinders.Furthermore, from DE 197 55 218 A1 a lock cylinder known in which an electronics for controlling a electromagnetic tumbler at an inaccessible Position is arranged within the housing. Therefore, must to service the electronics of the lock cylinder completely be dismantled. However, this leads to a lot extensive maintenance of the lock cylinder.

Aus der US 5,839,305 ist eine Schließeinrichtung bekannt geworden, bei der Batterien und eine elektronische Schaltung unterhalb eines Drehgriffs angeordnet sind. Der Drehknopf ist entfernbar, so dass nach seiner Entfernung die elektronische Schaltung zugänglich ist und manipuliert werden kann. Damit ist die Schließeinrichtung nicht zuverlässig vor Manipulationen geschützt.From US 5,839,305 a locking device is known become, at the batteries and an electronic circuit are arranged below a rotary handle. Of the Knob is removable, so after its removal the electronic circuit is accessible and manipulated can be. So that the locking device is not reliably protected against manipulation.

Weiterhin ist die Steuerelektronik nach einer Entfernung des Griffs einfach zu warten, um beispielsweise eine Batterie zu überprüfen oder zu wechseln. Die Entfernung des Griffs ohne Berechtigung zum Entriegeln der erfindungsgemäßen Schließeinrichtung wird jedoch verhindert, da die mit dem Griff und am Kern verbundene Welle in verriegelter Stellung der erfindungsgemäßen Schließeinrichtung formschlüssig mit dem Gehäuse verbunden ist. Daher läßt sich der Griff erst nach dem Entriegeln der erfindungsgemäßen Schließeinrichtung entfernen. Die mit dem Kern verbundene und in entriegelter Stellung der Schließeinrichtung lösbare Hülse hat den Vorteil, daß sich der Griff nach der Entriegelung der Schließeinrichtung erst abnehmen läßt, wenn die Hülse von der Welle getrennt wurde.Due to this design, the invention requires Locking device no sliding contacts or induction loops for the transmission of electrical energy or Control signals between the core and the housing or the Reader. The locking device according to the invention is therefore particularly reliable against manipulation and interference protected. Furthermore, the control electronics is after a removal of the handle easy to wait, for example to check or change a battery.

Eine Trennung des Formschlusses zwischen der Hülse und der Welle gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn das Halteteil bei entriegelter Schließeinrichtung mittelbar oder unmittelbar von einem von der Außenseite des Gehäuses bewegbaren Riegel gehalten ist. Hierdurch läßt sich nach einer Entriegelung der Schließeinrichtung und einer Bewegung des Riegels das Halteteil aus der Ausnehmung entfernen. Anschließend läßt sich der Griff zusammen mit der Welle von dem Gehäuse trennen.A separation of the positive connection between the sleeve and the wave is designed according to another advantageous Development of the invention particularly constructive easy if the holding part with unlocked locking device directly or indirectly from one of the outside the housing is held movable latch. This can be after unlocking the Locking device and a movement of the bolt that Remove the retaining part from the recess. Then leaves the handle together with the shaft of the housing separate.

Der Riegel läßt sich an einer besonders leicht zugänglichen und von dem Halteteil entfernten Stelle des Gehäuses anordnen, wenn das Halteteil auf einem von dem Riegel verschiebbaren Stift aufliegt und wenn der Stift in eine ein Entfernen des Halteteils aus der Ausnehmung ermöglichende Position bewegbar ist.The bolt can be attached to a particularly easily accessible and remote from the holding part of the housing Arrange when the holding part on one of the bolt slidable pin rests and when the pin in a a removal of the holding part from the recess enabling Position is movable.

Die Bewegung des Halteteils aus der oder in die Ausnehmung erfordert gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einen besonders geringen baulichen Aufwand, wenn der Riegel einen in dem Gehäuse gelagerten zylindrischen Abschnitt und einen den Stift halternden Exzenter aufweist und wenn der zylindrische Abschnitt Mittel zum Ansetzen eines Drehwerkzeugs hat.The movement of the holding part out of or into the recess requires according to another advantageous development the invention has a particularly low structural Effort when the latch mounted in the housing cylindrical section and a pin holder Eccentric and if the cylindrical section Has means for applying a turning tool.

Ein Klemmen des Halteteils in der Ausnehmung läßt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn das Halteteil als Kugel ausgebildet ist und wenn eine Trennebene zwischen der Hülse und der Welle im Bereich der zu der Achse der Welle weisenden Hälfte des Halteteils verläuft. Hierdurch wird das Halteteil von der Trennebene weg nach radial außen und damit gegen das Gehäuse oder den vom Riegel gehaltenen Stift gedrückt.Clamping of the holding part in the recess can be according to another advantageous embodiment of the invention Just avoid using the holding part as a ball is formed and if a dividing plane between the Sleeve and shaft in the area of the axis of the shaft pointing half of the holding part runs.

Die erfindungsgemäße Schließeinrichtung hat eine besonders hohe Zuverlässigkeit, wenn die Hülse mit dem Sperrmechanismus zusammenarbeitet.The locking device according to the invention has a special high reliability when the sleeve with the locking mechanism cooperates.

Der Schließmechanismus ermöglicht eine nahezu beliebige Kombination von Griffen und Schließmechanismen an seinen Enden, wenn zwischen der Hülse und einem die Schließeinrichtung verriegelnden Schließbart eine von dem zweiten Griff betätigbare Kupplung angeordnet ist. Hierdurch kann mit dem zweiten Griff beispielsweise die Schließeinrichtung ohne Abfrage einer Zugangsberechtigung oder von einem Schlüssel zu betätigende mechanische Stiftzuhaltungen zugeordnet werden.The locking mechanism allows almost any Combination of handles and locking mechanisms to his Ends when between the sleeve and one the locking device locking cam one of the second Handle operable coupling is arranged. This can with the second handle, for example, the locking device without requesting an access authorization or from a Key operated mechanical pin tumblers be assigned.

Die erfindungsgemäße Schließeinrichtung gestaltet sich besonders kompakt, wenn die Welle als Hohlwelle zur Aufnahme von Bauteilen der Kupplung ausgebildet ist.The locking device according to the invention is designed particularly compact when the shaft is used as a hollow shaft for receiving is formed of components of the coupling.

Aus dem Code wird mit einem Speicherinhalt verglichen und in Abhängigkeit von dem Vergleich die Zugangsberechtigung festgestellt oder verneint. Alternativ dazu kann die Steuerelektronik 6 auch mit einer ebenfalls nicht dargestellten, neben der Schließeinrichtung angeordneten Tastatur eine Zahlenkombination abfragen oder ein Entriegeln der Schließeinrichtung nur während eines Zeitfensters zulassen.The access authorization can be determined in many ways become. For example, the control electronics 6 a code one before the cup-shaped handle 2 or in a not shown reader held transponder receive and evaluate. From the code comes with a Memory content compared and depending on the Comparison the access authorization found or denied. Alternatively, the control electronics 6 also with a likewise not shown, beside the Locking device arranged keyboard a number combination interrogate or unlock the locking device only allow during a time window.

Das Gehäuse 1 hat einen Flansch 12 zur Halterung der Steuerelektronik 6. Im Zentrum des Flansches 12 ist die mit dem Kern 4 verbundene Welle 13 hindurchgeführt. Die Welle 13 ist als Hohlwelle ausgebildet und mit dem Bodenbereich des topfförmigen Griffs 2 verschweißt. Die Welle 13 ist in der eingezeichneten Normalstellung der Schließeinrichtung drehfest mit einer Hülse 14 verbunden. Die Hülse 14 ist über eine Kupplung 15 drehfest mit dem Schließbart 5 verbunden und hat die Ausnehmung 9 für den Sperrmechanismus 7. Hierdurch läßt sich der die Steuerelektronik 6 übergreifende Griff 2 nur bei entriegeltem Sperrmechanismus 7 drehen.The housing 1 has a flange 12 for holding the Control electronics 6. In the center of the flange 12 is the with the core 4 connected shaft 13 passed. The Shaft 13 is formed as a hollow shaft and with the bottom portion the pot-shaped handle 2 welded. The wave 13 is in the indicated normal position of Locking device rotatably connected to a sleeve 14. The sleeve 14 is rotatably connected via a clutch 15 with the Lock 5 is connected and has the recess 9 for the Locking mechanism 7. This allows the control electronics 6 overlapping handle 2 only when unlocked Turn lock mechanism 7.

Die Hülse 14 und die Welle 13 weisen eine fluchtende Ausnehmung 16 auf. In der Ausnehmung 16 ist ein Halteteil 17 zur Erzeugung eines Formschlusses zwischen der Welle 13 und der Hülse 14 angeordnet. In der eingezeichneten entriegelten Stellung des Schließmechanismus liegt das Halteteil 17 auf einem Stift 18 auf. Der Stift 18 wird von einem Riegel 19 mit einem Exzenter 20 gehalten. Der Riegel 19 ist mit einem zylindrischen Abschnitt 21 in dem Gehäuse 1 gelagert. Durch eine Drehung des Riegels 19 läßt sich der Stift 18 nach unten hin bewegen, so daß das Halteteil 17 aus der Ausnehmung 16 herausfallen kann. Hierdurch wird die drehfeste Verbindung der Hülse 14 mit der Welle 13 gelöst. Der topfförmige Griff 2 kann damit zusammen mit der Welle 13 aus dem Gehäuse 1 gezogen werden, um beispielsweise die Batterie 11 zu wechseln.The sleeve 14 and the shaft 13 have an aligned recess 16 on. In the recess 16 is a holding part 17th for generating a positive connection between the shaft 13 and the sleeve 14 is arranged. In the unlocked marked Position of the locking mechanism is the holding part 17 on a pin 18 on. The pin 18 is from a latch 19 held with an eccentric 20. The bolt 19 is provided with a cylindrical portion 21 in the Housing 1 stored. By a rotation of the bolt 19th can the pin 18 move downwards, so that the Holding member 17 can fall out of the recess 16. As a result, the rotationally fixed connection of the sleeve 14 with the shaft 13 solved. The cup-shaped handle 2 can thus be pulled out of the housing 1 together with the shaft 13, for example, to change the battery 11.

Durch eine Drehung des Kerns 4 mittels des zweiten Griffs 3 läßt sich die Kupplung 15 trennen und damit die drehfeste Verbindung zwischen dem Schließbart 5 und der Hülse 14 aufheben. Damit kann von dieser Seite her unabhängig von einer Zugangsberechtigung die Schließeinrichtung entriegelt werden. Selbstverständlich kann das der Steuerelektronik 6 gegenüberliegende Ende des Kerns 4 anstelle des zweiten Griffs 3 auch einen Schließkanal für einen Schlüssel und mechanische Stiftzuhaltungen oder einen weiteren elektronischen Sperrmechanismus aufweisen.By a rotation of the core 4 by means of the second handle 3, the clutch 15 can be separated and thus the non-rotatable Connection between the lock bit 5 and the sleeve 14 cancel. This can be independent from this page unlocks the locking device from an access authorization become. Of course, that can be the control electronics 6 opposite end of the core 4 instead the second handle 3 also has a closing channel for one Keys and mechanical pin tumblers or one have another electronic locking mechanism.

Figur 2 zeigt eine Schnittdarstellung durch die Schließeinrichtung aus Figur 1. Hierbei ist zu erkennen, daß die Ausnehmung 16 für das Halteteil 17 nach radial innen hin verjüngend gestaltet ist. Das Halteteil 17 ist als Kugel ausgebildet. Die Trennebene zwischen der Welle 13 und der Hülse 14 verläuft in der oberen Hälfte des Halteteils 17. Hierdurch wird bei einer Verdrehung der Hülse 14 gegenüber der Welle 13 das Halteteil 17 nach unten hin gegen den Stift 18 gedrückt. Um das Halteteil 17 aus zumindest dem in der Welle 13 vorhandenen Teil der Ausnehmung 16 zu entfernen, muß der Riegel 19 wie in Figur 1 dargestellt um 180° gedreht werden. Hierfür hat der Riegel 19 einen zum Ansetzen eines Schraubendrehers vorgesehenen Schlitz 22.Figure 2 shows a sectional view through the Locking device of Figure 1. It can be seen here that the recess 16 for the holding part 17 radially is tapered inside. The holding part 17 is designed as a ball. The dividing plane between the shaft 13 and the sleeve 14 extends in the upper half of Holding part 17. This is at a rotation of the Sleeve 14 relative to the shaft 13, the holding part 17 down pushed against the pin 18. To the holding part 17 from at least the existing in the shaft 13 part of To remove recess 16, the latch 19 as shown in FIG 1 shown rotated by 180 °. For this has the Latch 19 provided for attaching a screwdriver Slot 22.
