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 The present invention relates to a door locking system with a door leaf unit, the at least one movable latch and / or a movable bolt has, and a frame unit, the at least one recess has, the latch and / or bolt are provided for closing in the Grip recess.

Door locks are already known for a long time. The known door locks have generally a door leaf unit on, in which mostly both a trap for closing and easy locking, as well as a bolt for locking the door is integrated. This door leaf unit is in the door leaf used. additionally is a frame unit that integrates into the door frame or door frame is provided. This frame unit generally has both for the Trap as well for the latch has a recess. To lock the door it is provided that the bolt and / or the latch from the door leaf unit be moved out into the recess of the frame unit.

The Latch with a locking device, for example with a door handle, actuated be so that the latch from the recess of the frame unit in the door leaf unit withdraws. Whether the door itself open in the process lets is however dependent from the position of the latch.

The Latch is mechanical with the help of a key from the door leaf unit pulled out or in. The key generally exercises a bolt shaft connected to the bolt a mechanical force out. Bolt and bolt shaft are usually locked by a bolt guide pin, the firmly in the door leaf unit is mounted, guided, so that Bolt and bolt shaft only forward or back can move. To move the bolt out or in from the door leaf unit through manipulation or shocks To prevent a guard locking is often provided, which is in the idle state is pressed against the bolt shaft by a tumbler spring. The tumbler has corresponding projections and / or recesses, which in corresponding recesses and / or projections of the Bolt shaft intervene so that when the tumbler with the Bolt shaft has engaged, it is not possible to move the bolt. Now becomes the key turned in the castle, so leads the key two operations in a row out. First presses he the tumbler against the spring force of the tumbler spring from the Bolt shaft away, eliminating any locking hooks and / or locking recesses the guard locking disengage from the bolt shaft. After that kicks the key bit engages with the bolt shaft. By turning the key further the bolt advanced until the key bit with the bolt shaft again except Intervention device, whereupon the tumbler from the tumbler spring again in the direction the bolt shaft pressed and the corresponding catch hooks are moved accordingly Enter recesses in the bolt shaft. With the described embodiment only offers the shape of the keyhole Security against unauthorized opening, because this is done is that only a key belonging to the lock curly beard introduced can be. Such a castle is but mostly simply with the help of a curved nail or other simple tools to open.

Around the security of door lock systems increase, there are already locks, where not just one, but several tumblers are installed. In general, a locking pin is firmly attached to the locking shaft connected. The tumblers have notches with the locking pin engage. The individual tumblers are of different lengths. Becomes a graduated key turned in the castle, the steps raise the tumblers of different lengths, so that the locking pin is simultaneously disengaged from all tumblers and the latch then moves by moving the key bit can move.

A the so-called. represents a further improvement in the security of door locking systems Security lock. core the security lock is a cylinder. This cylinder is rotatable in a housing stored. Are inside the case several pins arranged by means of springs on the cylinder depressed become. Separate are also different in the cylinder itself long pens arranged. If there is no key in the cylinder, so can the cylinder pins through the body pins be pushed far inside the cylinder. So penetrate the housing pins something in the cylinder and block it. If now the right one key inserted into the cylinder are due to the pin serrations the pins of the cylinder pushed up so far that they do not over the outer contour protrude from the cylinder and at the same time the housing pins do not penetrate the cylinder. The cylinder with the bolt communicates, can then be rotated so that the lock can be opened can. Using an incorrect key usually only part of the locking pins raised to the correct height so that the rest Pins still prevent opening.

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

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

Compared to the The prior art described lies in the present invention hence the task of providing a door locking system that is easy to use, has increased security and preferably in existing doors retrofitted can be.

This Task is through a door locking system solved with a door leaf unit, the at least one movable latch and / or a movable bolt has, and a frame unit, the at least one recess has, latch and / or bolt are provided for this, to lock to engage in the recess, the door panel unit being an electrical Engine that for the closing and opening movement of latch and / or latch is provided.

According to the invention completely on a locking cylinder or a manually operated locking device waived. The latch, on the other hand, is opened with the help of a in the door leaf unit provided motor moves. One keyhole or one protruding outwards lock cylinder is therefore no longer necessary. Rather, it is possible, at least that external fitting to do so the existence Drill-proof fitting label protects the electric motor. But even if it were possible with the help of a drill in the door leaf unit penetrate, so could nevertheless the latch cannot be moved as there is no hand operated Mechanics is provided. The fact that the electric motor in the door leaf unit and is not arranged in the frame unit, is a subsequent one adapt existing door locking systems easy, because the existing mechanics including bolt and / or latch are still used can be, if desired.

How already executed, can the door locking system according to the invention both in new doors as well even in existing doors to be built in. When retrofitting of the door locking system according to the invention in existing doors However, there are sometimes difficulties in supplying power to the electrical Engine. Since there is generally no electrical in the door leaf unit Connection available is on more or less hidden place a cable can be laid. This However, it is usually difficult to do and, for example with glass doors, not without unwanted ones optical effects possible.

Therefore according to the invention is a special preferred embodiment proposed in which the frame unit has a power supply, who also for the supply of the electric motor of the door leaf unit is provided. The door frame or the door frame let yourself much easier and above all less noticeable with electrical current supply. In addition, many existing doors have electric doors Door opener already anyway a connection to an electrical power grid. The fact that the electrical feed for the electrical Motor in the door leaf unit via the frame unit done, there is no need to lay a new cable.

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

In a particularly preferred embodiment it is intended that electrical Transfer energy inductively from the frame unit to the door leaf unit becomes. Due to the inductive energy transfer, the corresponding Contacts are dispensed with, which is partly due to security issues Advantage is and secondly enables that existing latch and / or latch frame of the door leaf unit and continue to use the edging of the recesses of the frame unit.

The inductive transmission can take place, for example, by means of two coils arranged corresponding to one another. A coil is provided in the door leaf unit and a coil in the frame unit. Now the excitation coil is in the frame supplied with AC voltage, it generates an alternating magnetic field. The receiver coil in the door leaf unit is due to its arrangement in close proximity to the excitation coil capable of converting the alternating electromagnetic field into alternating voltage, so that the door leaf unit is supplied with alternating voltage without the need for mechanical electrical contact or a cable. Here too, energy is only transmitted when the door is closed, since only then are the excitation and receiver coils arranged in close proximity to one another.

It goes without saying it also possible that both in the door leaf unit and more than one coil is arranged in the frame unit.

With The door leaf unit has an advantage an energy storage element, preferably in the form of a battery. This allows the one to be transferred Energy density can be significantly reduced as the energy transferred successively is stored in the energy storage element. Is in the door leaf unit, For example, to move the bolt, more energy is required than is transmitted by the frame unit, the stored energy in the energy storage element can thus be accessed become.

The Control of the electric motor can, for example, by a electrical control element, such as a keyboard Enter a code.

Especially however, the frame unit preferably has a transmission unit and the Door leaf unit one Receiving unit. For example, it is possible that the frame unit with a Remote control, for example in the form of a switch, connected is. If the switch is now operated, this causes the transmitter unit to send a corresponding signal to send, which in turn from the receiving unit of the door leaf unit Will be received. In the door leaf unit the electric motor is then activated and the bolt is opened moved accordingly. Because in existing door locking systems there is space for the door leaf unit is generally very limited by the arrangement according to the invention by the sending and receiving unit to be dispensed with, others to accommodate space-consuming controls in the door leaf unit.

A Another particularly preferred embodiment provides that the door leaf unit a transmitting unit and the frame unit has a receiving unit. For example, it is possible that the Door panel unit Sends status messages to the frame unit, which in turn processes them accordingly can be. 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 into the door leaf unit intrude, triggered a signal which is transmitted to the frame unit.

With The door leaf unit has an advantage at least on one side a manual operation for moving the trap and / or of the bolt. For example, a door handle on the inside of the door be attached with the without using a key Door to be opened can.

in the general is common however the door leaf unit not installed exactly in all directions. However, this leads on adaptation problems between the electric motor on the one hand and the not exactly aligned door leaf unit. This can be done in in the worst case, the engine may freeze. But even if the engine does not stall, it generally suffers the complete mechanics and above all the fastening of the motor drive under this mismatch, so that the unit over the course of Time becomes unstable on the door leaf wobbles and finally is no longer usable.

According to the invention provided in a particularly preferred embodiment that with the electric motor a drive axle or shaft is connected, which in turn is connected to a drive axis, the one has catches engaging with bolt and / or latch, the connection between the drive axle or shaft and the driving axle Game. Through this embodiment with play it is guaranteed that a sticking of the engine did not take place. Mismatches caused by the incorrect alignment of the door leaf unit or mortise lock unit caused to be easily balanced without the electrical Engine runs the risk of its attachment solved to become.

Especially an embodiment is preferred, where the drive axle or shaft and the driving axle in about cursing with each other. Among other things, that the due to the mismatch of the mortise lock unit preferably be kept low.

In a further particularly preferred embodiment it is provided that one of the axes, that is to say either the drive axis or shaft or the driver axis at the connection between the drive axis or shaft and driver axis, at least in sections has 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 polygonal, particularly preferably right-hand one has cross-sectional inner contour, the cross-sectional inner contour of the one axis and the cross-sectional outer contour of the other axis are matched to one another in such a way that the area with the cross-sectional outer contour engages with play in the recess with the cross-sectional inner contour, so that when the drive axis or shaft rotates, the two contours engage with each other. This construction ensures that, on the one hand, the power transmission from the drive motor to the locking unit is divided in two, which is achieved by providing a connection with play, so that any mismatching of the mortise lock unit in the door leaf can be compensated, and on the other hand, reliable driving of the driving axis is achieved ,

alternative could instead of a game intervention between the drive axle or shaft and drive axle also a universal joint are provided, which could also easily compensate for slight misalignments.

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

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 responsible for the energy supply of the system and also optionally as a communication interface.

The frame unit 2 is from the power supply 3 powered. In the described embodiment, the power supply is used 3 for supplying power to the command and display unit 6 and the multi-channel transceiver 5 in the frame unit 2 , The power supply 3 here has an AC voltage output and a stabilized DC voltage output. The AC voltage output is for the induction coils 4 provided and accordingly strongly dimensioned. The power supply or control unit 3 also has a relay and connection board that serves as an interface to and from external systems such as video surveillance systems, access control systems, intrusion detection systems and fire alarm systems.

In 4 the schematic structure of the frame unit is shown. The frame unit 2 has a connector board 7 , a command and display unit 6 , a multi-channel transmission and reception element 5 and two induction coils 4 on. The connector board 7 has a connection terminal strip for the reception and distribution of all necessary connection and connection lines. Furthermore, the connection board serves as a connecting element between the command and display unit 6 and transmitting and receiving unit 5 , An optocoupler is preferably used here.

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

The system shown here has both a latch and a latch. Similar to known security locking systems, the electric motor is able to unlock both the bolt and the latch, that is, to pull it into the door leaf. If the door is closed, there are basically two options. Either the latch is simply snapped into place, or the bolt is additionally pushed out of the door leaf into the frame. Is therefore on the command and display unit 6 If the switch is actuated for unlocking, it does not matter whether only the latch has to be withdrawn or whether a complete unlocking process, that is to say the retraction of the bolt and the latch, has to be initiated. The lock motor 9 identifies a position for this, so that the system can automatically select the corresponding process. Since, as already mentioned, the command and display unit 6 In the secured area, i.e. on the inside of the door, identification can generally 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 provide a corresponding identification device, such as a receiving device for a transponder.

As A display unit or an LED module can be provided in the display unit become. Can on the display unit all system relevant states and Messages are displayed. moreover for example, is it possible to integrate a timer into the command and display unit, so the closure for example takes place automatically at a certain time. For example, authorities or Institute doors be programmed so that they at a certain time for Open to the public are so that they opened by any user can be and at other times only with the help of an identification medium are to be opened.

The sending and receiving unit 5 communicates with a corresponding transmission and reception unit of the door leaf unit (not shown in 4 ). Via the sending and receiving unit 5 can the frame unit 2 with the door leaf unit 1 communicate. Coded messages are sent for this purpose. The coding should preferably be selected so that a different coding is used for each door security system, that is to say for each door. In other words, the transmitting and receiving unit is the door leaf unit 1 so coordinated that they receive messages and commands exclusively from the sending and receiving unit 5 the frame unit 2 accepted.

With the help of the receiving and transmitting unit 5 Various system status information can also be recorded. For example, if the door is open, the door leaf unit receives 1 no voltage from the induction coils 4 the frame unit 2 , The absence of the supply voltage is caused by the transmitter and receiver unit of the door leaf unit 1 captures what in turn the sending and receiving unit 5 the frame unit 2 can be communicated. This makes it possible to determine whether the door 11 is open or closed. Via the connection board 7 All essential messages are forwarded to any existing higher-level or subordinate third-party systems, such as access, video, intrusion and fire alarm systems.

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

Some messages and commands from the sending and receiving unit are described below as examples 5 either to the door leaf unit 1 or can be transferred to the subordinate external systems or can be received by them:

Open: Will this command from the sending and receiving unit 5 to the door leaf unit 1 is transmitted by the door leaf unit 1 the electric motor 9 controlled so that the trap is withdrawn.

Lock: Will this command from the sending and receiving unit 5 to the door leaf unit 1 transmitted, so the bolt from the door leaf unit 1 in the recess of the frame unit 2 extends. The door leaf unit can be advantageous 1 the successful closing of the door 11 report so that, if the success message is omitted, appropriate measures, such as the sounding of a warning tone, can be taken.

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

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

Ambient temperature: By a suitable arrangement of a thermometer or a thermal contact Is it possible, to give a warning message to an external system if the ambient temperature 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 can be opened if a component is opened without authorization or if an attempt is made to drill open via the transmitter and receiver unit 5 forwards a message to an external system.

The induction coils 4 are in continuous operation in the embodiment shown. You will find the connector board 7 directly on the power supply 3 operated via the AC voltage output. They are there for the door leaf unit 1 to supply with inductive energy.

The door leaf unit 1 consists in the preferred embodiment of two parts, the inner fitting and the outer fitting. The door leaf unit 1 is in 2 shown in an exploded view. The inner fitting preferably consists of an inner fitting plate 17 and an inner base plate 23 , On the hardware label 17 is a door handle 25 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 outside fitting label 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. On the inner base plate 23 is a guide sleeve 20 rotatably attached, in the drive shaft 27 is provided by the electric motor 9 is operated. The drive shaft 27 is with a driver 26 connected, which engages with the bolt or the bolt shaft. The guide sleeve 20 preferably has the shape of a lock cylinder. This ensures that the door locking system according to the invention can be easily retrofitted in existing doors. Particularly when the door locking system according to the invention is to be retrofitted, it is advantageous if the length of the sleeve corresponds approximately to the thickness of the door leaf. This ensures that the sleeve 20 uses the mechanical breakpoints of conventional locking cylinders, which leads to increased mechanical strength. In order not to have a specially made guide sleeve for every door leaf thickness 20 to need, it is further proposed according to the invention that to extend the guide sleeve 20 Individual spacers are strung together and screwed together, so that the sum of the length of the guide cylinder 20 and the thickness of the spacers corresponds approximately to the door leaf thickness. When assembling the door security system, the fitter can decide on site how many and, if necessary, which spacers are strung together in order to achieve the optimum overall length.

The inner base plate 23 that also in the 3 and 5 has the induction receiving coils 4 , a unit of energy 16 , a transmitting and receiving unit 5 , a connector board 24 , an engine unit 9 , a self-monitoring unit 10 as well as evaluation electronics 8th on.

From the above it follows that the system according to the invention can also be easily retrofitted to existing doors and locking systems, since only the inside fittings and outside fittings as well as the locking cylinder have to be exchanged, while the entire remaining lock mechanism can otherwise remain in one door. All essential parts of the new system, that is to say in particular the induction coils, an energy unit, a motor, etc., are arranged on the fittings, in particular on the inner fitting or its base plate. A corresponding reading unit for reading an electronic key card or the like or another identification system can be provided on the outer fitting. 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 adapted in shape to a conventional lock cylinder and can easily replace it, but has no keyhole or comparable functional element, but only a shaft with a driver that establishes the connection to the lock mechanism and corresponds to the driver of a conventional lock cylinder. It goes without saying that, however, a corresponding inner fitting generally turns out to be somewhat more voluminous and larger than a conventional inner fitting plate. In addition, induction coils of the door leaf unit, which are consequently also provided on the inner base plate, are provided as close as possible to the induction coils mounted in the frame unit.

Analogous to the induction coils 4 the induction coils are also part of the frame unit 4 the door leaf unit is designed for continuous operation. Is the door 11 closed, the coils are 4 arranged so that they are in the immediate vicinity of the transmitter coils 4 in the door frame unit 2 located. This ensures that the induction coils 4 the door leaf unit 1 within the magnetic field of the transmitter coils 4 the frame unit. This makes it possible to draw energy from the frame unit 2 to the door leaf unit 1 transferred to. With the energy thus transmitted, the door leaf unit 1 provided.

The energy unit 16 is possibly via the connection board 24 with the induction coils 4 connected. The received voltage is rectified and smoothed with the help of 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.

The sending and receiving unit 5 forms, as already explained, with the transmitting and receiving unit 5 the frame unit 1 a closed transmission and reception circuit. This allows control commands from the frame unit 2 received and messages to the frame unit 2 be transmitted. Control commands, such as those from the access control or from the command and display unit 6 received "opening" is on the connector board on the motor unit 9 transmitted, which then withdraws the latch of the mortise lock and holds it for a time specified by the access control, in order to then fall back into the original position.

Furthermore, the sending and receiving unit 5 the door leaf unit 1 able to receive messages from the self-monitoring unit 10 are transmitted to the frame unit 1 or to transmit the downstream third-party systems. With the sending and receiving unit 5 it 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 on. Only when an induction voltage is present does the transmitting and receiving unit send 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 often the door is open.

The connector board 24 includes a connection terminal strip for the reception and distribution of all necessary connection and connection lines. Furthermore, an interface to the components of the outside door fitting, in particular to the connection points of the sabotage contacts and the surface drilling protection, is provided on the connection board.

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 non-rotatably connected to the base plate. The drive shaft is driven by a gearbox 27 in the guide sleeve 20 turned. The driver moves with it 26 on the drive shaft 27 and thus engages in the linkage of the castle or in the bolt shaft.

The In principle, the motor has only one stop in each direction of rotation. The end of each direction of rotation is indicated by the in the castle or in striking plate predetermined mechanical dimensions or stops. That is why it is for the locking system no matter whether it is a one-turn or multi-turn castle. The lock always closes completely closed or fully open.

At the Close the motor turns in the closed direction until the locking tongue either completely turned out, or the tongue in the striking plate has hit the stop. In this case the motor is blocked and draws an increased current. This current increase is used to switch off the engine. This power shutdown happens very quickly to damage to avoid the mechanics, gearbox and motor. After the shutdown the entire facility remains in this position.

At the catch up the motor turns in the upward direction until the locking tongue is complete screwed in and the trap withdrawn is. It drives the motor to the mechanical relationship of the mortise lock. In in this case the motor is blocked and draws an increased current. This current increase will used to turn off the engine. This current shutdown happens very quickly to damage to avoid the mechanics, gearbox and motor. After the shutdown the entire facility remains in this position, that is also the trap remains withdrawn, the door can open become. Either on control command of the access control or after at a fixed time, the motor turns in the closed direction until the Trap has free play in the spring force and in the so-called zero position drove. No force is exerted on the mortise lock in this position.

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

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

at with the command "open door" the motor turns the corresponding direction. In other words, the engine, whether the door just closed, that is only the trap is snapped, or even locked, this means the bolt extended, moved in the opening direction until the bolt and the trap withdrawn are. When the trap is withdrawn can the door open become.

The optional self-monitoring unit 10 is responsible 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 external fitting as well as the temperature of the interior.

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

In the event that the drilling protection or lifting contact sends a signal to the self-monitoring system due to external force, the self-monitoring system also switches on the acoustic alarm and initiates it via the transmitting and receiving unit 5 sending an alarm message.

As well when the temperature has a corresponding value, e.g. 60 ° C, exceeds an acoustic alarm is triggered and forwarded an alarm message. Appropriate escape routes keep open, the lock is then automatically unlocked, this means the trap withdrawn and recorded.

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

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

In the base plate 19 bores and threads are made, which are screwed to the inner base plate 23 and the fitting label 18 enable.

On the base plate 19 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 the fitting label 18 intended. In a preferred embodiment, the fitting label comprises 18 a receiving device 22 for receiving appropriately coded signals.

optional can be an ad for the condition of the locking system, e.g. "open" and "closed" should be provided. additionally can be a malfunction indicator be provided, especially in connection with intrusion detection systems is of particular advantage. The status and / or fault display can optically and / or acoustically.

Furthermore, the transmitter and receiver unit ( 5 ) communication with a burglar alarm center is possible. For example, signals or messages such. B. "Arming readiness" or the success message "locked" (= armed), from or to the control center. For example, it is possible for the “arming” of the intrusion detector to depend on successful identification of an identification medium.

The hardware label 18 is equipped with a drilling protection that is connected in series with the lifting contact on the base plate. The lifting contact secures the fitting label 18 against violent prying open. If an intrusion alarm system is provided, the triggering of the lifting contact can be transmitted to the intrusion alarm center.

In the 6 and 7 are exemplary two preferred embodiments of the invention shown door security system. In 6 shows an application as it can be used for example in existing door security systems. The outside fitting has protection against drilling and sabotage 28 an identification receiving device 30 as well as a command and display unit 22 on. Receives the identification receiving device 30 a corresponding signal, this is done via the connection boards 24 of the outside and inside fittings to the evaluation electronics 8th forwarded to the base plate of the interior fitting. If the signal is identified, the motor unit 9 controlled accordingly and the door can be opened or closed. At the in 7 The embodiment shown is on the identification receiving device 30 been waived. Here, the door is only released by an access control system, which can work with video surveillance, for example.

In the 8a to 8c the door leaf unit and the mortise lock unit are shown schematically in three different views. The mortise lock unit has a trap here 31 and a latch 32 on. As in 8a can be seen, the mortise lock is ideally installed along the ideal line 33 , However, this is practically never the case. Rather, it occurs, for example, in the 8a shown view often to a tilting error, which is also referred to as a horizontal error. This is in the 8a to 8c through the actual lines 34 has been clarified. Due to this tilting it happens that the trap 31 and latch 32 not with the vertical ideal line 33 cursed, but something tipped out of it. It can be the same as in 8b a vertical error is shown. Also in 8b are the trap 31 and the latch 32 to recognize. In contrast to 8a in which the door leaf view is shown is in 8b the fold view shown. Finally in 8c a plan view of the mortise lock unit shown to illustrate that here also deviations from the ideal line 33 can occur as through the actual lines 34 is shown. Even if in reality the deviations from the target line are frequent 33 are not as big as that in the 8a to 8c For better understanding, such mismatches, as has already been stated, lead to disadvantages in the connection between the drive unit on the one hand and the mortise lock unit on the other hand. This disadvantage is overcome by the embodiment described below.

Another embodiment of the present invention is shown in FIGS 9 to 11 shown. This embodiment differs only by a special connection technology between the motor or drive shaft 27 on the one hand and mortise lock unit 38 or driving axle 35 on the other hand.

In 9 is the guide sleeve 20 shown in a top view and a cross-sectional view. It can be clearly seen that the guide sleeve 20 in plan view has approximately the shape of a conventional locking cylinder. In the cross-sectional view it is clear that the guide sleeve 20 is designed as a profile saddle.

As in 10 can be seen, the guide sleeve 20 a through hole through which the driver axis 35 stretches with the carrier 26 is connected, in the embodiment shown here with a driver tongue 36 is provided. The driver 26 is arranged such that it is between the two U-shaped legs of the guide sleeve 20 located. The hole 37 is used to attach the guide sleeve 20 in the door leaf unit. The guide sleeve 20 forms together with the driving axis 35 and the driver 26 the mortise lock unit 38 , As in both the cross-sectional view and the top view in 10 you can see the drive axis 35 specially designed in the embodiment shown here. At one end is a section 39 provided with a non-round cross-section. In the embodiment shown, the cross section, as in particular in the top view in FIG 10 is clearly recognizable, essentially rectangular, but the corners have been rounded. this section 39 with a non-round cross-section extends in the form of a pin in the direction of the driving axis 35 , In 11 is in a cross-sectional view in addition to the mortise lock unit already described 38 the drive unit 40 shown. The drive unit 40 consists essentially of the drive shaft 27 , which is characterized by the inner base plate 23 extends and a gear 41 for connection to the electric motor via a gear, not shown in this figure. It can be clearly seen that the drive shaft 27 a recess 42 has, which corresponds to the outer contour of the pin 39 is trained. In the present case, the drive shaft has 27 a recess 42 with an essentially rectangular inner contour. When installing, drive shaft 27 and drive shaft 35 moved towards each other in the direction of the arrow so that the pin-like section 39 the drive shaft 35 into the recess 42 the drive shaft 27 intervenes. The cone-like section 39 has in the recess 42 the drive shaft 27 a certain game, so that any tilting of the driving axis 39 can be compensated for from the ideal line due to an imprecise installation of the mortise lock in the door leaf. On the other hand, the drive axle 27 due to its non-round inner contour when rotating about its axis, the non-round pin-like section 39 seize and the driving axis 35 turn accordingly. The resulting torsional tolerances are with this arrangement Not disadvantageous, since these can be compensated with the control electronics. In the embodiment shown, the peg-like area has 39 the driving axis 35 Dimensions of approximately 10 mm × 4 mm × 3 mm. This dimensioning ensures that the door locking system functions reliably.
