Abstract

The door unit (1) includes an electric motor driving the locking and unlocking movements of the latch or bolt in the frame unit (2) recess.

Description

The present invention relates to a door locking system with a door leaf unit, which has at least one Movable latch and / or a movable bolt, and a frame unit, the at least has a recess, the latch and / or bolt being provided for closing to reach into the recess.

Door locks have been known for a long time. The known door locks generally have a door leaf unit, in which usually both a latch for locking and easy locking, as well as a bolt for locking the door is integrated. This door leaf unit is in the door leaf used. There is also a frame unit that is integrated in the door frame or door frame is provided. This frame unit generally shows both for the trap and for the latch has a recess. To lock the door it is provided that the bolt and / or the latch can be moved out of the door leaf unit into the recess of the frame unit.

The latch can be operated with a closing means, for example with a door handle, so that the latch retracts from the recess in the frame unit into the door leaf unit. Whether the door can be opened, but depends on the position of the bolt.

The bolt is mechanically pulled out of the door leaf unit using a key. The key generally exercises on a bolt shaft connected to the bolt a mechanical force. Bolts and bolt shafts are usually connected by a bolt guide pin, which is firmly mounted in the door leaf unit, guided, so that bolt and bolt shaft can only move forward or back. To move the bolt out or in Preventing the door leaf unit from manipulation or vibrations is often a guard locking provided that pressed in the idle state by a tumbler spring against the bolt shaft becomes. The tumbler has corresponding projections and / or recesses that correspond to the corresponding ones Recesses and / or projections of the locking shaft engage so that when the tumbler has engaged with the bolt shaft, a movement of the bolt is not possible. Becomes now the key is turned in the lock, the key executes two operations in succession. First, he pushes the tumbler against the spring force of the tumbler spring from the bolt shaft away, causing any locking hooks and / or locking recesses of the tumbler with the bolt shaft disengage. The key bit then engages with the latch shaft. By Turning the key further, the bolt is advanced until the key bit with the bolt shaft comes out of engagement again, whereupon the tumbler from the tumbler spring again in the direction of the locking shaft is pressed and the corresponding catch hooks are moved accordingly Enter recesses in the bolt shaft. In the described embodiment offers only the shape of the keyhole security against unauthorized opening, as it is designed that only a key belonging to the lock with a curved beard can be inserted. On However, such a lock is usually simple with the help of a curved nail or other simple Open tools.

To increase the security of door lock systems, there are locks that do not only one, but several tumblers are installed. A locking pin is generally fixed here connected to the bolt shaft. The tumblers have notches that engage the locking pin. The individual tumblers are of different lengths. If a stepped key in the Turned the lock, the steps raise the tumblers of different lengths, so that the locking pin is disengaged simultaneously with all tumblers and the bolt then through the Can move the key bit.

The so-called security lock represents a further improvement in the security of door locking systems The centerpiece of the security lock is a cylinder. This cylinder is rotatable in stored in a housing. Several pins are arranged inside the housing, which can be connected with the aid of Springs are pressed onto the cylinder. Separate are also different in the cylinder itself long pens arranged. If no key is inserted in the cylinder, the cylinder pins can be pulled through the housing pins are pushed far into the interior of the cylinder. This will penetrate the housing pins something in the cylinder and block it. If now the right key in the cylinder is inserted, the pins of the cylinder are pushed up just enough due to the pin serrations, that they do not protrude beyond the outer contour of the cylinder and at the same time the housing pins do not penetrate the cylinder. The cylinder that is connected to the bolt can then be turned so that the lock can be opened. When using the wrong one As a rule, only part of the locking pins are raised to the correct height that the remaining pins still prevent opening.

In principle, however, the mechanical locking process runs in all known door locking systems essentially in the same way. Even the so-called security locks can be opened with suitable unlocking tools, such as a lock pick or by boring, open even without a suitable key. In the meantime, instructions for use are already available on the Internet and tools for opening door locking systems without a suitable one Key spread.

The weak point of the known door locking systems is the mechanical operability of the bolt from the door leaf. For this reason, it has already been proposed in DE 197 43 655, for example an additional locking / unlocking device within the frame unit to be provided within the bolt which is advanced from the door leaf unit into the frame unit of the frame. The locking or unlocking device is here from the bolt work of the castle completely independent. Unlocking takes place here when a coded unlock signal is broadcast by a transmitter that is only available to an authorized person. disadvantage this locking system, however, is that both a transmitter for operating this door locking system as well as the mechanical key must be used.

Compared to the prior art described, the object of the present invention is therefore to provide a door locking system that is easy to use, one has increased security and can be retrofitted in existing doors if possible.

This task is solved by a door locking system with a door leaf unit that has at least one Movable latch and / or a movable bolt, and a frame unit, the at least has a recess, the latch and / or bolt being provided for this purpose Closing to engage in the recess, the door leaf unit being an electric motor has, which is provided for the closing and opening movement of the bolt and / or latch.

According to the invention, therefore, a lock cylinder or a manually operated locking device is used entirely waived. The bolt, however, is provided with the help of a in the door leaf unit Motors moves. A keyhole or an outwardly protruding locking cylinder is accordingly not necessary anymore. Rather, it is possible to carry out at least the outer fitting in such a way that a drill-proof fitting shield protects the electric motor. But even if it succeeded penetrate the door leaf unit with the help of a drill, the bolt could still not be moved because no mechanically operated mechanism is provided. The fact that the electrical Motor in the door leaf unit and not in the frame unit is a retrofit Retrofitting existing door locking systems is easy because the existing mechanics including the bolt and / or trap can be used if desired.

As already stated, the door locking system according to the invention can be used both in new doors and can also be installed in existing doors. When retrofitting the invention However, there are sometimes difficulties with door locking systems in existing doors in the power supply for the electric motor. Since generally no in the door leaf unit If there is an electrical connection, a cable must be laid at a more or less hidden location become. However, this is usually only difficult to accomplish and, for example with glass doors, not possible without undesirable optical effects.

A particularly preferred embodiment is therefore proposed according to the invention, in which the frame unit has a power supply, which is also used to supply the electric motor the door leaf unit is provided. The door frame or the door frame is much easier and, above all, supply electrical power more inconspicuously. In addition, many existing ones Doors already have a connection to an electrical one due to their electric door opener Power on. The fact that the electrical feed for the electric motor in the door leaf unit If the frame unit is used, there is no need to lay a new cable.

The energy transfer from the frame unit into the door leaf unit can, for example, thereby the door leaf unit and frame unit each have electrical connection contacts, which engage with each other at least when the door is closed. The fact that the electric motor in the door leaf unit is only connected to the power supply, when the door is closed is without disadvantage, since in this position the need is anyway only consists of moving the latch and / or the bolt.

In a particularly preferred embodiment it is provided that electrical energy is inductive is transmitted from the frame unit to the door leaf unit. Through inductive energy transfer corresponding contacts can be dispensed with, for safety reasons is advantageous and on the other hand enables the existing bolt and / or trap bezel To continue to use the door panel unit and the edging of the recesses in the frame unit.

The inductive transmission can be carried out, for example, by two mutually correspondingly arranged Coils are done. There is a coil in the door leaf unit and a coil in the frame unit intended. If the excitation coil in the frame unit is now supplied with AC voltage, so it creates an alternating magnetic field. The receiver coil in the door leaf unit is due their location in close proximity to the excitation coil is able to detect the electromagnetic Implement alternating field in alternating voltage, so that the door leaf unit with alternating voltage is supplied without the need for mechanical electrical contact or a cable. Also Here, energy is only transmitted when the door is closed, since the excitation and Receiver coil are arranged in close proximity to each other.

Of course, it is also possible that both in the door leaf unit and in the frame unit more than one coil is arranged.

The door leaf unit advantageously has an energy storage element, preferably in the form of a rechargeable battery, on. As a result, the energy density to be transmitted can be significantly reduced, since the transmitted one Energy is successively stored in the energy storage element. Is in the door leaf unit, for moving the latch, for example, requires more energy than is transmitted by the frame unit the stored energy in the energy storage element can be accessed.

The electrical motor can be activated, for example, by an electrical control element, such as a keyboard for entering a code.

However, the frame unit particularly preferably has a transmission unit and the door leaf unit has one Receiving unit. So it is possible, for example, that the frame unit with a remote control, for example in the form of a switch. If the switch is now operated, causes the transmitter unit to send a corresponding signal, which in turn from the Receiving unit of the door leaf unit is received. The electrical one is then in the door leaf unit Motor controlled and the bolt is moved accordingly. Because in existing door locking systems the space for the door leaf unit is generally very limited by the invention Arrangement of transmitter and receiver unit to be dispensed with, further space-consuming To accommodate controls in the door leaf unit.

Another particularly preferred embodiment provides that the door leaf unit is a transmitting unit and the frame unit has a receiving unit. For example, it is possible that the door leaf unit sends status messages to the frame unit, which in turn accordingly can be processed further. For example, the charge status of the batteries can be transmitted become. Furthermore, it is possible to connect a drilling protection to a sensor in such a way that when trying to enter the door leaf unit, a signal is triggered which leads to the Frame unit is transmitted.

The door leaf unit advantageously has a manual actuation for moving at least on one side the latch and / or the latch. For example, one can be found on the inside of the door Door handle can be attached, with which the door can be opened without using a key.

In general, however, the door leaf unit is often not installed exactly in all directions. This however, leads to adjustment problems between the electric motor on the one hand and the not exactly aligned door leaf unit. In the worst case, this can cause the motor to freeze to lead. But even if the engine does not stall, the entire mechanics generally suffers and especially the attachment of the motor drive under this mismatch, so that the unit becomes unstable over time, wobbles on the door leaf and eventually becomes unusable is.

According to the invention it is therefore provided in a particularly preferred embodiment that with the electric motor a drive axle or shaft is connected, which in turn with a Driver axis is connected, which engages with a bolt and / or latch engaging driver has, wherein the connection between the drive axis or shaft and driver axis has play. This embodiment with play ensures that the motor does not jam. In addition, mismatches caused by the incorrect alignment of the door leaf unit or the mortise lock unit are caused to be easily compensated without the electrical Engine runs the risk of being detached from its mounting.

An embodiment is particularly preferred in which the drive axis or shaft and the driver axis roughly aligned with each other. This ensures, among other things, that due to the mismatch of the mortise lock unit occurring torques kept as low as possible become.

In a further particularly preferred embodiment it is provided that one of the axes, that means either the drive axle or shaft or the driver axle at the connection between Drive axis or shaft and driver axis, at least in sections, a non-round, preferably polygonal, particularly preferably rectangular cross-sectional outer contour and the other axis has a recess which, at least in sections, has a correspondingly non-round, preferably has polygonal, particularly preferably rectangular cross-sectional internal contour, the Cross-sectional inner contour of one axis and the cross-sectional outer contour of the other axis in this way are coordinated that the area with the cross-sectional outer contour with play in the Recess engages with cross-sectional inner contour, so that when turning the drive axis or - wave the two contours engage with each other. This construction ensures that on the one hand the power transmission from the drive motor to the clamping unit is divided into two is achieved by providing a connection with play so that any mismatches in the Mortise lock unit in the door leaf can be compensated, and on the other hand a reliable one Drive of the driving axis is achieved.

Alternatively, instead of a play intervention between the drive axle or shaft and driving axle a universal joint may also be provided, which also has slight misalignments could easily compensate.

A door 11 is shown in FIG. In the door leaf is a door leaf unit 1 with a door handle 14 intended. The door 11 is surrounded by a door frame 12 into which the door frame unit 2 is inserted is. The door frame unit is connected to a control and power supply unit 3, which in turn is connected to the power supply 13. The door frame block can here via the power supply 3 or the line 15 also with other systems, such as an access control or video surveillance, be connected.

The door locking system according to the invention consists of the door leaf unit 1 and the door frame unit 2. The door frame unit 2 is primarily for powering the system and continues optionally responsible as communication interface.

The frame unit 2 is supplied with voltage by the power supply unit 3. In the described embodiment the power supply unit 3 serves to supply power to the command and display unit 6 and the multi-channel transceiver 5 in the frame unit 2. The power supply 3 has one here AC voltage output and a stabilized DC voltage output. The AC voltage output is provided for the induction coils 4 and is accordingly strongly dimensioned. The power or control part 3 also has a relay and connection board, which acts as an interface from and to external systems, e.g. Video surveillance systems, access control systems, intrusion detection systems as well as fire alarm systems.

The schematic structure of the frame unit is shown in FIG. The frame unit 2 has one Connection board 7, a command and display unit 6, a multi-channel transmission and reception element 5 and two induction coils 4. The connection board 7 has a terminal block for the reception and distribution of all necessary connecting and connecting lines. Furthermore serves the connection board as a connecting element between command and display unit 6 and Transmitter and receiver unit 5. An optocoupler is preferably used here.

The command and display unit 6 of the frame unit 2 does not necessarily have to be in the frame unit can be arranged, but can for example also in a connected via the line 15 External system can be integrated. In the embodiment shown, the command and Display unit 6 on the inside of the door. For example, it has two control switches with which the door security system can be controlled. One switch is for unlocking, the other intended for locking.

The system shown here has both a latch and a bolt. Similar to known ones The electric motor is able to lock both deadbolts and security locking systems to unlock the trap, that is, to pull it into the door leaf. If the door is closed, then there are basically two options. Either it's just snapped into place, or it's additional the latch is pushed out of the door leaf into the frame. Is therefore on the command Display unit 6 operated the switch for unlocking, so it does not matter whether only the trap must be withdrawn, or whether a complete unlocking process, that is Withdrawal of the bolt and the trap, must be initiated. The lock motor 9 indicates this a position detection so that the system automatically selects the appropriate process can. Since, as already mentioned, the command and display unit 6 is in the secured area, that is located on the inside of the door, can generally be identified to be dispensed with. In other words, the command and display unit 6 is freely accessible and can be operated by everyone. Of course, however, it is possible to find a corresponding one here Identification device, such as a receiving device for a transponder, provided.

A screen or an LED module can be provided as the display unit. On the display unit all system-relevant states and messages can be displayed. Moreover, it is for example possible to integrate a timer in the command and display unit, so that for example, the closure takes place automatically at a specific time. For example Government or institute doors can be programmed to operate at a specific time are open to the public so that they can be opened by any user, and too other times can only be opened with the help of an identification medium.

The transmission and reception unit 5 communicates with a corresponding transmission and reception unit the door leaf unit (not shown in Figure 4). Via the transmitting and receiving unit 5 can the frame unit 2 communicate with the door leaf unit 1. For this, coded messages Posted. The coding should preferably be selected so that for each door security system means a different coding is used for each door. In other words, the broadcast and Receiving unit of the door leaf unit 1 is coordinated such that it receives messages and commands exclusively accepted by the transmitting and receiving unit 5 of the frame unit 2.

With the aid of the receiving and transmitting unit 5, various system status information can also be obtained be recorded. If, for example, the door is open, the door leaf unit receives 1 no voltage from the induction coils 4 of the frame unit 2. The lack of the supply voltage is detected by the transmitting and receiving unit of the door leaf unit 1, which in turn Transmitting and receiving unit 5 can be communicated to frame unit 2. This makes it possible determine whether the door 11 is open or closed. About the connector board 7 are all essential messages to any existing higher-level or subordinate external systems, such as. Access, video, intrusion and fire alarm systems, forwarded.

For example, it is possible to provide a thermal contact or a thermometer in the system, the transmitting and receiving unit 5 communicating a connected fire alarm system can, if a maximum temperature is exceeded.

Öffnen: Wird dieser Befehl von der Sende- und Empfangseinheit 5 an die Türblatteinheit 1 übertragen, wird von der Türblatteinheit 1 der elektrische Motor 9 angesteuert, so daß die Falle zurückgezogen wird.

Zuschließen: Wird dieser Befehl von der Sende- und Empfangseinheit 5 an die Türblatteinheit 1 übertragen, so wird der Riegel aus der Türblatteinheit 1 in die Ausnehmung der Rahmeneinheit 2 erstreckt. Mit Vorteil kann die Türblatteinheit 1 das erfolgreiche Zuschließen der Tür 11 mitteilen, so daß, falls die Erfolgsmeldung unterbleibt, entsprechende Maßnahmen, wie beispielsweise Ertönen eines Warntons, ergriffen werden können.

Aufschließen: Wird dieser Befehl von der Sende- und Empfangseinheit 5 an die Türblatteinheit 1 gesendet, so wird der Riegel zurückgezogen. Auch hier ist es unter Umständen von Vorteil, wenn der erfolgreiche Aufschließvorgang von der Türblatteinheit 1 an die Sende- und Empfangseinheit 5 der Rahmeneinheit 2 übermittelt wird.

Wechselspannungsausfall, Gleichspannungsausfall und Ladespannungsausfall: Fällt aus irgendwelchen Gründen eine der genannten Spannungen aus, so ist die Sende- und Empfangseinheit 5 in der Lage, diese Störung nachgeordneten Fremdsystemen weiterzumelden, so daß von dort aus entsprechende Maßnahmen ergriffen werden können.

Umgebungstemperatur: Durch geeignete Anordnung eines Thermometers oder eines Thermokontakts ist es möglich, eine Warnmeldung an ein Fremdsystem zu geben, wenn die Umgebungstemperatur einen bestimmten Wert, z.B. 60°C, überschreitet. Des weiteren ist es möglich, das System so zu konfigurieren, daß dann, wenn die Umgebungstemperatur den bestimmten Wert überschreitet, das Schließsystem sich automatisch öffnet, um eventuelle Fluchtwege zu öffnen.

Sabotage: Es ist beispielsweise möglich, einen Sabotagekontakt oder Deckelkontakt vorzusehen, der bei unberechtigtem Öffnen einer Komponente bzw. einem Aufbohrversuch über die Sende- und Empfangseinheit 5 eine Nachricht an ein Fremdsystem weiterleitet.

In the following, some messages and commands are described as examples, which can be transmitted by the transmitting and receiving unit 5 either to the door leaf unit 1 or to the downstream third-party systems or can be received by them:

Opening: If this command is transmitted from the transmitting and receiving unit 5 to the door leaf unit 1, the electric motor 9 is actuated by the door leaf unit 1, so that the latch is withdrawn.

Lock: If this command is transmitted from the transmitting and receiving unit 5 to the door leaf unit 1, the latch is extended from the door leaf unit 1 into the recess in the frame unit 2. Advantageously, the door leaf unit 1 can report the successful closing of the door 11, so that, if the success message is omitted, appropriate measures can be taken, such as a warning tone being sounded.

Unlocking: If this command is sent from the sending and receiving unit 5 to the door leaf unit 1, the bolt is withdrawn. Here, too, it may be advantageous if the successful unlocking process is transmitted from the door leaf unit 1 to the transmitting and receiving unit 5 of the frame unit 2.

AC voltage failure, DC voltage failure and charging voltage failure: If, for any reason, one of the voltages mentioned fails, the transmitting and receiving unit 5 is able to report this fault to third-party systems, so that appropriate measures can be taken from there.

Ambient temperature: With a suitable arrangement of a thermometer or a thermal contact, it is possible to send a warning message to an external system if the ambient temperature exceeds a certain value, e.g. 60 ° C. Furthermore, it is possible to configure the system so that when the ambient temperature exceeds the certain value, the locking system opens automatically to open any escape routes.

Sabotage: It is possible, for example, to provide a sabotage contact or cover contact which forwards a message to an external system via the transmitting and receiving unit 5 if an unauthorized opening of a component or an attempted drilling is carried out.

In the embodiment shown, the induction coils 4 are in continuous operation. You will about that Connection board 7 operated directly on the power supply 3 via the AC voltage output. they are there to supply the door leaf unit 1 with inductive energy.

In the preferred embodiment, the door leaf unit 1 consists of two parts, the inner fitting and the outside fitting. The door leaf unit 1 is shown in an exploded view in FIG. The inner fitting preferably consists of an inner fitting plate 17 and an inner base plate 23. On the fitting plate 17, a door handle 25 is provided with which the door can be opened manually if it is not locked by the bolt.

Other components of the door leaf unit are the outer base plate 19 and the outer fitting plate 18. In the outer base plate 19 and the inner base plate 23 holes are provided, so that the outer fitting plate 18 together with the outer base plate 19 and the inner base plate 23 can be attached to the door leaf. A guide sleeve 20 is on the inner base plate 23 rotatably attached, in which a drive shaft 27 is provided, which is by the electric motor 9th is operated. The drive shaft 27 is connected to a driver 26 which is connected to the bolt or the bolt shaft engages. The guide sleeve 20 is preferably in the form of a locking cylinder. This ensures that the door locking system according to the invention easily in already existing doors can be retrofitted. Especially when the invention Door locking system to be retrofitted, it is advantageous if the length of the sleeve in about Thickness of the door leaf corresponds. This ensures that the sleeve 20 is the mechanical breakpoints the conventional lock cylinder uses, resulting in increased mechanical strength leads. In order not to require a custom-made guide sleeve 20 for each door leaf thickness further proposed according to the invention that 20 individual to extend the guide sleeve Spacers are strung together and screwed together so that the sum of the lengths of the guide cylinder 20 and the thickness of the spacers approximately corresponds to the door leaf thickness. When installing the door security system, the installer can then decide how many and, if necessary, which spacers are lined up in order to achieve the optimum To achieve overall length.

The inner base plate 23, which is also shown in FIGS. 3 and 5, has the induction receiving coils 4, a power unit 16, a transmitting and receiving unit 5, a connection board 24, a Motor unit 9, a self-monitoring unit 10 and evaluation electronics 8.

From the above it follows that the system according to the invention also with existing doors and locking systems can be retrofitted very easily, since only the inside fittings and outside fittings as well as the lock cylinder must be replaced, otherwise the entire remaining lock mechanism can remain in one door. All essential parts of the new Systems, in particular the induction coils, a power unit, a motor etc. are on the fittings, in particular arranged on the inner fitting or its base plate. On the outside fitting can a corresponding reading unit for reading an electronic key card or the like or another identification system can be provided. Of course this identification system can also be mounted on the frame or elsewhere on the Outside of the door. The guide sleeve 20 is in the form of a conventional locking cylinder adapted and can easily replace this, but has no keyhole or similar Functional element on, but only a shaft with a driver that connects to Manufactures lock mechanics and corresponds to the driver of a conventional lock cylinder. It it goes without saying that a corresponding interior fitting is generally somewhat more voluminous and is larger than a conventional interior fitting label. In addition, induction coils of the door leaf unit, which are therefore also provided on the inner base plate, as close as possible to the provided induction coils mounted in the frame unit.

Analog to the induction coils 4 of the frame unit are also the induction coils 4 of the door leaf unit designed for continuous operation. If the door 11 is closed, the coils 4 are arranged that they are in the immediate vicinity of the transmitter coils 4 in the door frame unit 2 is located. This ensures that the induction coils 4 of the door leaf unit 1 inside of the magnetic field of the transmitter coils 4 of the frame unit. This makes it possible To transfer energy from the frame unit 2 to the door leaf unit 1. With the so transmitted Energy is supplied to the door leaf unit 1.

The energy unit 16 is optionally connected to the induction coils 4 via the connection board 24 connected. The voltage received is rectified and smoothed using a rectifier and fed to a charge controller. The charge controller ensures the optimized energy level in the downstream batteries (not shown), with the voltage of which the system is operated.

As already stated, the transmitting and receiving unit 5 forms with the transmitting and receiving unit 5 of the frame unit 1 a closed transmission and reception circuit. This allows Receive control commands from frame unit 2 and transmit messages to frame unit 2 become. Control commands, such as those from the access control or from the command and display unit 6 "Open" is received via the connection board to the motor unit 9 transferred, which then withdraws the latch of the mortise lock and for one of which Access control records the specified time in order to then return to the original position.

In addition, the transmitting and receiving unit 5 of the door leaf unit 1 is able to send messages that are transmitted by the self-monitoring unit 10 to the frame unit 1 or the downstream ones To transmit external systems. With the transmitting and receiving unit 5 can be determined whether the door is closed or open. If the door is open, there is no induction voltage on the door leaf or the induction coils 4. Only if an induction voltage is present, the sending and receiving unit sends a message or "polling" to the frame unit. This "polling" does not take place when the door is open. This ensures that the frame unit 2 or a subordinate external system can monitor how long and how often the Door is open.

The connector board 24 includes a terminal block for receiving and distributing all necessary connecting and connecting lines. There is also an interface on the connection board to the components of the outside door fitting, in particular to the connection points of the sabotage contacts and the surface drilling protection provided.

The motor unit 9 has a powerful DC motor with gear 29, clutch, position control, Control and limit switch on.

The electric motor 9 is rotatably connected to the base plate. The drive shaft is driven by a gearbox 27 rotated in the guide sleeve 20. The driver 26 thus moves on the drive shaft 27 and thus engages in the linkage of the castle or in the bolt shaft.

In principle, the motor has only one stop in each direction of rotation. The end of each direction of rotation will due to the mechanical dimensions or stops specified in the lock or in the striking plate certainly. That is why it is the same for the locking system, whether it is a single-turn or multi-turn castle. The lock always closes completely or completely.

When locking, the motor turns in the closed direction until the locking tongue either completely turned out, or the locking tongue in the striking plate has reached the stop. In this case the motor is blocked and draws an increased current. This current increase is used to the Switch off the engine. This power cut-off happens very quickly to prevent damage to the mechanics, Avoid gearbox and motor. After the shutdown, the entire facility remains in this Position.

When unlocking, the motor turns in the upward direction until the locking tongue is fully screwed in and the trap is withdrawn. The engine moves to the mechanical relationship of the Mortise. In this case the motor is blocked and draws an increased current. This Current increase is used to shut down the engine. This current shutdown happens a lot fast to avoid damage to the mechanics, gearbox and motor. After the shutdown the entire device remains in this position, i.e. the trap remains retracted, the door can be opened. Either on the control command of the access control or after a fixed one Time the motor turns in the closed direction until the latch has free play in the spring force and into the so-called zero position is driven. In this position, no force is exerted on the mortise lock exercised.

Thus, the door locking system according to the invention is on almost all conditions on a door to be used without the need for large adjustments or adjustment work. The conversion from DIN left to DIN right doors is done by simply plugging the motor connection cable and by turning the induction unit over.

The control commands for the motor unit 9 are from the frame unit 1, that is, the control and Control unit 6, transmitted via the transmitting and receiving elements 5. It will be essentially only two different commands, namely "open door" and "close door" are required. In a preferred embodiment provides that the command is only executed when no fault is reported by the self-monitoring unit 10. The motor then turns the shaft 29 until the driver 26 has reached the limit switch position and remains in this Position.

With the command "Open door" the motor turns in the corresponding direction. In other words the motor, regardless of whether the door is only closed, simply snaps the latch is, or is even blocked, i.e. the bolt is extended, moved in the opening direction as long as until the bolt and latch are withdrawn. If the trap is withdrawn, the door can be opened.

The optional self-monitoring unit 10 is for the central monitoring and control function of the entire system. The energy unit is monitored, i.e. the failure of the AC voltage, the DC and charging voltage, the sabotage line and the lifting contacts of the outside fitting and the temperature of the interior.

If, for example, the inductive AC voltage is missing, this could have several reasons, e.g. power failure or door open. Since the battery charging circuit is interrupted in this case, the self-monitoring switches an acoustic alarm. For example, a warning tone sounds every 10 seconds.

In the event that the drill protection or lifting contact is triggered by external force sends to the self-monitoring, the self-monitoring also switches the acoustic alarm and causes the sending and receiving unit 5 to issue an alarm message.

Likewise, if the temperature has a corresponding value, e.g. 60 ° C, exceeds an acoustic Alarm triggered and an alarm message forwarded. Open to appropriate escape routes to hold, the lock is then automatically unlocked, that is, the latch is withdrawn and held.

An evaluation unit 8 is also provided, which is provided for evaluating coded signals is. This is connected to a receiving device, which is preferably on the outside fitting is appropriate. This receiving device is intended to receive any authorization signals receive. These can be radio signals or optical signals, for example. Furthermore, the Common transponder technology with contactless reading technology or other code card readers or a keypad for entering code numbers or a combination of several Systems are used.

As already mentioned, the outside door fitting consists of a fitting plate 18 with a base plate 19. The outer fitting here has a door knob 21.

In the base plate 19 holes and threads are introduced, which are screwed to the Allow inner base plate 23 and the fitting plate 18.

On the base plate 19 there is a connection board 24 as a connecting element between the evaluation and Control electronics on the inside and the display and control elements 22 of the fitting plate 18 provided. In a preferred embodiment, the fitting plate 18 comprises one Receiving device 22 for receiving appropriately coded signals.

Optionally, a display for the status of the locking system, e.g. "open" and "closed" be provided. In addition, a fault display can be provided, which is particularly in Connection with intruder alarm systems is particularly advantageous. The status and / or fault display can be done optically and / or acoustically.

Furthermore, by means of the transmitting and receiving unit (5) there is communication with an intrusion alarm center possible. For example, signals or messages such. B. "Arming readiness" or the success message "locked" (= arming) from or to the Headquarters are transferred. It is possible, for example, to "arm" the intrusion detector depend on successful identification of an identification medium.

The fitting plate 18 is provided with a drilling protection, which is in series with the lifting contact the base plate is connected. The lifting contact secures the fitting plate 18 against violent Levering. If an intrusion alarm system is provided, the lifting contact can be triggered to the intrusion control panel.

FIGS. 6 and 7 exemplify two preferred embodiments of the invention Door security system shown. In Figure 6 an application is shown, such as can be used with existing door security systems. The outside fitting points next to the drilling and sabotage protection 28 an identification receiving device 30 and a command and display unit 22. The identification receiving device 30 receives a corresponding one Signal, so this is on the connection boards 24 of the outer and inner fittings the evaluation electronics 8 forwarded to the base plate of the inner fitting. If the signal is identified, the motor unit 9 is controlled accordingly and the door can be opened or closed become. In the embodiment shown in Figure 7 is on the identification receiving device 30 have been waived. Here, the door is only released by an access control system, that can work with video surveillance, for example.

In Figures 8a to 8c, the door leaf unit and the mortise lock unit are each in three different Views are shown schematically. The mortise lock unit here has a latch 31 and a latch 32. As can be seen in FIG. 8a, the mortise lock is installed ideally along the ideal line 33. However, this is practically never the case. Rather, it happens, for example in the view shown in Figure 8a often to a tilting error, which is also called horizontal Error is referred to. This has been illustrated in FIGS. 8a to 8c by the actual lines 34. Due to this tilting it happens that the latch 31 and bolt 32 are not perpendicular Ideal line 33 are aligned, but something tipped out of this. It can be the same as in figure 8b, a vertical error occurs. In Figure 8b, the trap 31 and Bar 32 can be seen. In contrast to Figure 8a, in which the door leaf view is shown, is in Figure 8b shows the fold view. Finally, in Figure 8c is a top view of the mortise lock unit shown to clarify that deviations from the ideal line 33 also occur here can, as shown by the actual lines 34. Even if in reality the deviations are common of the target line 33 are not as large as that in FIGS. 8a to 8c for the better Understanding has been indicated, such mismatches, as has already been stated, to disadvantages in the connection between the drive unit on the one hand and mortise lock unit on the other hand. This disadvantage is overcome by the embodiment described below.

A further embodiment of the present invention is shown in FIGS. 9 to 11. This Embodiment differs only by a special connection technology between Motor or drive shaft 27 on the one hand and mortise lock unit 38 or driver axis 35 on the other.

In Figure 9, the guide sleeve 20 is shown in a plan view and a cross-sectional view. Clear It can be seen that the guide sleeve 20 is approximately in the form of a conventional plan view Has locking cylinder. In the cross-sectional view it is clear that the guide sleeve 20 as a profile saddle is trained.

As can be seen in FIG. 10, the guide sleeve 20 has a through hole through which extends the driver axis 35, which is connected to the driver 26, that shown in FIG Embodiment is provided with a driver tongue 36. The driver 26 is such arranged that it is located between the two U-shaped legs of the guide sleeve 20. The bore 37 is used to fasten the guide sleeve 20 in the door leaf unit. The guide sleeve 20 forms, together with the driver axis 35 and the driver 26, the mortise lock unit 38. As can be seen in both the cross-sectional view and the top view in FIG the driver axis 35 is specially designed in the embodiment shown here. On hers one end has a section 39 with a non-round cross section. In the shown The embodiment is the cross section, as can be clearly seen in particular in the top view in FIG. 10 is essentially rectangular, but the corners have been rounded are. This section 39 with a non-round cross section extends in the form of a pin in the direction the driver axis 35. In FIG. 11, in addition to that, a cross-sectional view already shows described mortise lock unit 38, the drive unit 40 shown. The drive unit 40 exists essentially from the drive shaft 27 which extends through the inner base plate 23 and a gear 41 for connection to the electric motor via one not in this figure has shown transmission. It can be clearly seen that the drive shaft 27 has a recess 42 has, which is designed according to the outer contour of the pin 39. In the present In this case, the drive shaft 27 has a recess 42 with an essentially rectangular shape Inner contour. During assembly, drive shaft 27 and drive shaft 35 are in the direction of the arrow so moved towards each other that the pin-like section 39 of the driver shaft 35 in the Recess 42 of the drive shaft 27 engages. The pin-like section 39 has in the recess 42 of the drive shaft 27 a certain play, so that any tilting of the driving axis 39 from the ideal line due to an imprecise installation of the mortise lock in the door leaf can be compensated. On the other hand, the drive axle 27 cannot because of it round inner contour when rotating about its axis, the non-round pin-like section Take 39 and turn the drive axle 35 accordingly. The resulting Torsion tolerances are not a disadvantage with this arrangement, since these are with the control electronics can be compensated. In the embodiment shown, the pin-like region 39 the driving axis 35 dimensions of about 10 mm x 4 mm x 3 mm. This dimensioning ensures the reliable functioning of the door locking system.
