Abstract

The device has a lock actuation sensor (49) for coupling to a lock cylinder (37) so that actuation of the lock cylinder can be detected by the sensor and a switch signal transmitter (57) with which an activation or deactivation signal can be sent to a break-in warning system on detection of operation of the lock cylinder.

Description

The invention relates to the activation and deactivation of an intrusion detection system (EMA), which secure the outer skin and the interior of a building. To the burglar alarm system after the Activate leaving the building or before entering the building To be able to deactivate the building without triggering a false alarm, it is known to be a handheld transmitter or an external key switch provided. By actuating the hand transmitter or the key switch can therefore be an activation or deactivation signal from the outside be transmitted to the intrusion detection system. Has this solution the disadvantage that an authorized person can trigger such Don't forget to send signals, otherwise the building accidentally remains unsecured or actually authorized entry of the secured building to trigger an intrusion alarm leads. An inevitability is therefore desirable, i.e. with the exit and authorized entry into the building, the activation should or deactivation of the intrusion alarm system triggered automatically become.

For this purpose it is known to have a bolt switch contact in the strike plate of the entrance door to install. If the entrance door by means of a locking cylinder and the associated key is locked, the detects Latch switch contact on the striking plate a locking state of Locking bolt and then transmits an activation signal to the intrusion detection system of the building. If due to authorized unlocking actuation of the locking cylinder the locking bolt from the bolt switch contact the bolt switch contact transmits a deactivation signal to the intrusion detection system, so that a The authorized user does not enter the building Burglar alarm. The disadvantage of this solution is that the assembly such a bolt switch contact can be very complex, in particular when attached to a metal frame.

Furthermore, a so-called block lock is known, in which in addition to such a bolt switch contact an integrated electromechanical Blocking mechanism is provided. This prevents the Intrusion alarm system, if there is an impermissible operating state, for example if the outer skin of the building is not working properly and is completely closed. Such a block lock has one undesirably complex construction.

The invention is therefore based on the requirement of an inevitable activation or deactivation of a burglar alarm system at low To allow assembly effort.

This task is solved by a door lock monitoring unit which is provided for a door-side attachment, and the one lock actuation sensor and has a switching signal transmitter, the Lock actuation sensor coupled or connectable to a lock cylinder is and is able to detect an actuation of the locking cylinder, and wherein the switching signal transmitter - upon detection of an actuation of the Lock cylinder - an activation or deactivation signal to a Burglar alarm system transmitted.

According to the invention, a lock actuation sensor is therefore arranged on the door side. This sensor registers if the locking cylinder of this door is justified, thus actuated by means of the associated identification means, in particular is rotated. This is a coupling of the lock actuation sensor provided with the lock cylinder. The sensor forms together at least with the switching signal transmitter, a door lock monitoring unit, which together as original equipment or retrofit module with additional locking and fitting elements on or inside the door in question is attached.

The door lock monitoring unit according to the invention thus offers the The advantage is that when the locking cylinder is actuated by the authorized user an inevitable activation or deactivation signal is able to produce without structural measures for this Door frame or on the striking plate of the relevant door are required. Instead, the door lock monitoring unit is in place of or in Addition of the locking cylinder attached to the door. This requires no special assembly work and no destructive fastening measures, because a certain area of the door for one anyway Attachment of locking and fitting elements is provided.

A particular advantage of the invention can be seen in the fact that the Door lock monitoring unit in a simple manner a conventional one Lock cylinder can replace, for example, at the beginning mentioned block lock as an additional lock in addition to an existing one Door lock is provided.

Another advantage of the invention compared to the above Latch switch contact is that no unauthorized deactivation the intrusion detection system by manipulating the striking plate of the Door can be triggered. With one arranged in the striking plate Latch switch contact, for example, there is a risk that it is manipulated by means of a wire inserted through the door gap. The door lock monitoring unit according to the invention, however, is due their door-side attachment for such manipulation not easily accessible.

Regarding the invention, it should also be noted that it applies to any type of locking cylinder can be used with the associated means of identification, in particular for conventional profile cylinders with keys or for electromechanical Locks with transponder or radio control.

It is preferred if the locking cylinder is an integrated component the door lock monitoring unit. Thus, an easy one Initial equipment or retrofitting of the door can be done by the door lock monitoring unit with lock cylinder as a structural unit instead a conventional lock cylinder is used. Alternatively the door lock monitoring unit can also be used as a supplementary unit for an existing, conventional locking cylinder can be realized, the mutual coupling, for example, by a suitable one Key section of the door lock monitoring unit is effected into an associated internal locking part of the existing locking cylinder is introduced and fixed there.

The coupling between the lock actuation sensor and the lock cylinder can be done in any way that a detection of a Activation of the lock cylinder enables. In particular, come one mechanical, electromagnetic, magnetostatic and / or an optical coupling into consideration.

The lock actuation sensor is preferably a rotary actuation sensor trained to detect a rotary actuation of the lock cylinder can. Alternatively or additionally, the sensor can be used for detection the direction of rotation to be formed between a Differentiate locking actuation and unlocking actuation to be able to.

In any case, it is preferred if the door lock monitoring unit is equally suitable for left and right-closing doors. To For this purpose it is possible, for example, to distinguish between the desired triggering of an activation signal or one Deactivation signal a simple alternating switching operation (Toggle). Furthermore, on the door lock monitoring unit a switch, for example a jumper, for one-time setting of the Differentiation between locking and unlocking direction be trained. It is also possible to use an electronic learning process to be provided, for example on the basis of the first actuation direction the locking cylinder by means of the associated identification means.

The lock actuation sensor can be, for example, an electromechanical one Motion sensor, an electromagnetic motion sensor (in particular a Hall effect sensor), an optical motion sensor (especially according to the principle of an optical computer mouse), an inductive motion sensor or a tilt sensor (in particular a mercury inclination sensor, another liquid inclination sensor or a tilt sensor with rolling balls) be educated.

Furthermore, it is preferred if the lock actuation sensor for an Essentially currentless monitoring of the locking cylinder is formed is. This can be realized by a "wake up" function which the lock actuation sensor or other electrical or electronic Only then set up the door lock monitoring unit activated and supplied with electrical energy if there has ever been a door lock actuation event. By Such a configuration of the sensor is the energy consumption Door lock monitoring unit in monitoring mode is therefore considerable reduced.

This essentially currentless monitoring can be done, for example realized by an electromechanical motion sensor, in particular by having at least one movable contact element, that only by actuating the lock cylinder to close a electrical circuit is initiated. For example, several freely movable, electrically conductive balls are provided, their position is evaluated in an energy-saving manner by electronics that are equipped with a Field effect transistor is equipped in the input.

Alternatively, a microswitch can be used for essentially currentless monitoring be provided by inserting the identification means into the Lock cylinder is operated.

The door lock monitoring unit according to the invention can be used for complete Accommodation should be provided within the door in question. However, for a universal installation of the door lock monitoring unit on doors to allow for the inclusion of a standard locking cylinder-in particular a profile cylinder - are prepared the door lock monitoring unit - at least partially - preferably provided for arrangement on the surface of the door, namely on the the side of the door facing away from the attack, i.e. on the inside of the building (or inside of apartment). For this purpose, it is preferred if the door lock monitoring unit has a housing which contains the lock actuation sensor, the switching signal transmitter and the other components at least partially. This housing can for example Shape of a cylinder or knob, i.e. one at its free end have widened cylinders.

It is further preferred if the door lock monitoring unit has a Actuating device that actuates the lock cylinder from the inside of the door. This actuator can be rotatably mounted on the door to rotate the Allow lock cylinder. In a preferred embodiment is this actuation device by the door lock monitoring unit itself or through the aforementioned housing of the door lock monitoring unit educated.

With regard to the actuating device mentioned, it is also preferred if the lock cylinder has an external locking part and a Has internal locking part by an emergency and danger clutch are interconnected. The external locking part is by means of the identification means of the lock cylinder actuated, such an actuation causes a movement of a locking bolt of the locking cylinder. The inner locking part is moved in order to detect the To enable actuation.

According to a preferred embodiment, the door lock monitoring unit has an activation suppression switch, by the Activation of the authorized persons - despite a subsequent locking or unlocking the lock cylinder - the transmission an activation or deactivation signal to the intrusion detection system can prevent. The activation suppress switch is thus with the lock actuation sensor and / or the switching signal transmitter connected that the inevitable activation explained or deactivation of the intrusion alarm system - at the request of the authorized user - exceptionally can be overridden.

For example, the following situation can occur: The authorized user would like to leave the building briefly during the day, for example to do a purchase. He wants to lock the front door, to secure the building against unauthorized access. Indeed this locking or the corresponding actuation of the Lock cylinder - exceptionally - not necessarily for activation the burglar alarm system because, for example, a pet in the Building remains enclosed due to interior surveillance could trigger a false alarm through the intrusion detection system. To activate the intrusion detection system in this situation - despite Lock actuation of the locking cylinder - suppressed, actuated the authorized user before leaving and locking the building the activation suppression switch on the door lock monitoring unit.

The activation suppression switch mentioned is preferably located on the inside of the building, for example on a housing of the door lock monitoring unit in order for the authorized user to be easily accessible. The switch is preferred designed as a push button switch. He can also with a time switch be connected, which ensures that after actuation of the Activation suppression switch was actuation of the lock cylinder only then not to an activation or deactivation signal leads when these two operations within a predetermined Time interval - for example 15 seconds.

In a corresponding manner, the door lock monitoring unit can be used as an alternative or additionally - have an activation trigger switch, by activating the person authorized to access the activation or Deactivation of the intrusion detection system can trigger without this To have to operate the lock cylinder. Thus one of these also serves Activation trigger switch for exceptionally breaking the explained, otherwise generally desirable inevitability of activation and deactivation of the intrusion alarm system. For example such a deactivation of the intrusion alarm system without corresponding Unlocking the lock cylinder may be desirable to monitor the interior of the building while securing the Outer skin - by locking the entrance door - still guaranteed should stay.

Conversely, it is also possible instead of basically inevitable activation of the intrusion alarm system an activation trigger switch use such that a locking operation of the Lock cylinder only then to transmit an activation signal the intrusion detection system leads, if previously - for example inside a prescribed time interval - the activation trigger switch has been operated.

According to a further advantageous development, the door lock monitoring unit has an optical and / or acoustic signaling device to display the respective activation status. For example a red / green LED provided on the inside of the building Locking state of the lock cylinder and the associated state Show signal transmission to the intruder alarm system. Possible are also one or two different acoustic signals to activate a lock and an unlocking operation of the lock cylinder display. Such a signal device can also be used for confirmation an actuation of the aforementioned activation suppression switch or activation trigger switch.

It is also advantageous if the door lock monitoring unit has its own energy source, especially an electric battery. With an autonomous energy supply, there is no need to the door lock monitoring unit with an external energy source, for example, to connect the public power grid in a complex manner.

Finally, the door lock monitoring unit has an advantageous Training an attack detector on who tried to break in can detect at the door and, if necessary, the transmission an attack detection signal via the switching signal transmitter to the intrusion detection system can trigger. In this embodiment, the Door lock monitoring unit not only as a pure control device for the intrusion detection system, but also as a detector for Burglary attempts used. This eliminates the need for Monitoring the door for attempts to break in an additional sensor provided.

The attack detector can in particular in or on the lock cylinder arranged and for detection of mechanical destruction, for example drilling or pulling the locking cylinder his. For example, a detection of a closing or Opening an electrical circuit can be provided. This is done an additional safeguard, for example, against that by boring and subsequent unauthorized actuation of the lock cylinder, the door lock monitoring unit to an unauthorized transmission of a Deactivation signal is initiated to the intruder alarm system.

Further embodiments of the invention are mentioned in the subclaims. The invention is explained below by way of example with reference to the drawings; in these show:

1A and. 1B

in two different views a part of a door frame and a door which is equipped with a locking device and a door lock monitoring unit according to the invention, and

Fig. 2

is a schematic cross-sectional view of this door.

1A and 1B show - from two different directions - one Frame 11 and a door 13 slightly open with respect to frame 11.

The door 13 has - in a known manner - on that shown in Fig. 1A Building inside 15, a handle 17 and a cover plate 19, and on the attack or building exterior 21 shown in FIG. 1B Handle plate 23 and a protective fitting 25. Furthermore, the door 13 has a - Also known per se - mortise lock 27, from the end face a lock latch 29 protrudes. The locking mechanism has one the front of the door 13 extendable locking bolt 31.

To accommodate the lock latch 29 and the locking bolt 31 is on the Frame 11 has a striking plate 33 with associated receiving openings.

According to the invention, the door 13 has a door lock monitoring unit equipped, of which in Fig. 1A and 1B, a cylindrical actuator housing 35 on the inside of the building 15 and a lock cylinder 37 too are recognizable, which extends up to the building exterior 21 of the door 13 extends. By rotating the actuator housing 35, the Lock bolt 31 extended from or into the mortise lock 27 be moved back to the door 13 from inside the building 15 optionally lockable.

The handle 17 enables the door 13 to be opened from the inside of the building 15 out. For this, the pusher 17 is - in a known manner - such coupled with the lock latch 29 that when the Handle 17 retracted the latch 29 into the mortise lock 27 becomes.

The door 13 can be opened from the outside 21 of the building, by turning the lock cylinder 37 by means of an associated key becomes. The locking bolt 31 and the lock latch 29 in the mortise lock 27 is moved back.

According to the invention, actuation of the locking cylinder 37 and thus the locking bolt 31 - regardless of whether this actuation of the building exterior 21 or via the actuating housing 35 from the Building inside 15 from - to generate an activation or Deactivation signal and transmission of this signal to a Burglar alarm system. This is explained below.

Fig. 2 shows that the lock cylinder 37, an outer locking part 39, a hereby coupled inner locking part 41 and a locking lug 43 having the outer locking part 39 and the inner locking part 41 is connected and also in a locking mechanism 45 intervenes. The locking mechanism 45 provides - in a manner known per se - For the described coupling of the handle 17 and the lock cylinder 37 with the lock latch 29 (not shown in FIG. 2) for this purpose the locking mechanism 45 is in particular via a square pin 47 connected to the pusher 17.

The door lock monitoring unit according to the invention points within of the actuating housing 35 - and thus in the interior of the building - A rotary actuation sensor 49 on a coupling shaft 51 mechanically with the inner locking part 41 and the outer locking part 39 of the lock cylinder 37 is coupled. About the coupling shaft 51 can be operated on the outside 21 of the building of the lock cylinder 37 by means of an assigned key 53 to the Rotary actuation sensor 49 are transmitted. On the other hand enables the coupling shaft 51 transmits a rotary operation of the operating case 35 on the lock cylinder 37, and thus on the Locking lug 43 and the locking mechanism 45 on the locking bolt 31 and the lock latch 29.

An electronic circuit is also located within the actuating housing 35 55 arranged, which serves as an evaluation and control device and with the rotary actuation sensor 49 and also in the actuation housing 35 integrated radio transmitter 57 is connected.

Circuit 55 is also provided with an activation suppress switch 59 connected, which partially protrudes from the actuating housing 35.

In addition, the door lock monitoring unit has an electrical one Battery 63 on with the purpose of an autonomous energy supply the rotary actuation sensor 49, the circuit 55 and the radio transmitter 57 connected and is also integrated in the actuating housing 35.

The door lock monitoring unit according to the invention enables one inevitable activation and deactivation of an intrusion detection system due to a locking operation or unlocking operation of the Lock cylinder 37 from the inside 15 of the building or the outside of the building 21 out. For this purpose, the rotary actuation sensor 49 monitors whether a rotational movement of the coupling shaft 51 relative to a reference point takes place, which is provided with respect to the door 13 in a fixed arrangement. For example, a reference point on a mounting plate Door lock monitoring unit (not shown) serve as a reference.

Such a rotary movement of the coupling shaft 51 therefore either occurs on, if the outer locking part 39 of the Lock cylinder 37 is actuated and via a - not shown - clutch the inner locking part 41 moves. On the other hand there is one such rotational movement of the coupling shaft 51 relative to the reference point, if that with the coupling shaft 51 - in a manner not shown - Rotatably connected actuating housing 35 is rotated to the Lock cylinder 37 and the locking bolt connected to it in one Bring locking position or an unlocking position.

If the rotary actuation sensor 49 such a rotary movement of the Coupling shaft 51 registered, it delivers a corresponding actuation signal to the circuit 55. This generally causes the radio transmitter 57 for immediate wireless transmission of an activation signal or a deactivation signal to the central intrusion detection system, each after whether by the rotary operation sensor 49 a lock operation or an unlocking actuation of the locking cylinder 37 is detected has been.

The door lock monitoring unit thus enables an inevitable Activation or deactivation of the intrusion alarm system without the Authorized access for this - in addition to locking or unlocking of the lock cylinder 37 - must act. The equipment of the Door 13 with the door lock monitoring unit has no special structural Measures and therefore possible without special assembly effort, because the door lock monitoring unit including the lock cylinder 37 simply inserted into the door 13 instead of the usual locking cylinder becomes.

In addition to the door lock monitoring unit shown, it should be noted that that - at the request of the person authorized to access - a suppression the inevitable activation or deactivation of the intrusion detection system allowed. For this purpose - before the operation of the Lock cylinder 37 by means of the actuating housing 35 or the key 53 - the activation suppression switch 59 actuated to the Circuit 55 indicate that a subsequent actuation signal of the Exceptionally, the rotary actuation sensor 49 is not for emitting a Lead activation or deactivation signal by the radio transmitter 57 should.

The door lock monitoring unit shown can also be a signal receiver, for example have a radio receiver to a enable bidirectional communication with the intrusion detection system, so that an operational or security status also from the intrusion detection system be reported to the door lock monitoring unit can.

Finally, it should be noted that instead of the radio transmitter 57 also a wired switching signal transmitter for forwarding the activation or Deactivation signal can be provided. The same applies to the mentioned signal receiver.
