Description

The invention relates to a burglar alarm and alarm system, preferably for apartments in single and multi-family houses or in residential complexes. The other possible uses extend to all types of commercial premises and are also available to a certain extent in industrial plants. A new type of electromechanical switch lock with mutually different switching functions is an inseparable part of the overall system.
The aim of the invention is to prevent, aggravate and reduce crimes such as burglary, theft, threat, robbery, vandalism. The complex creation of electronic burglar alarm and intrusion detection systems in connection with emergency call and service control centers enable comprehensive protection and assistance. Timely reporting and the correct detection and response, as well as precise knowledge of where and in what type of help is required at short notice, considerably increases the protective effect. A good preservation of evidence facilitates the procedure in the executive and legal area.

With the new burglar alarm and alarm system and the associated new arrangement of the modules, which includes a generally new concept of the key switch, excellent property and personal protection is guaranteed. This affects all interested sections of the population, single citizens, elderly and sick people and children.
When using the door lock with the different switching functions from inside or outside, different security requirements are taken into account, ie when staying in the apartment or when leaving.

Property can also be protected when you are away or on vacation. For those in need who are in their apartment and are unable to reach the alarm system located at a specific location, the invention also provides an excellent application.
According to the known state of the art, there are various possibilities for transmission from emergency calls to agencies providing assistance. Security and patrol personnel are currently increasingly replacing property protection with technical systems. However, the combination of technical signaling systems, combined with inspection tours by personnel commissioned to do so, provides optimal protection.
Patent step DE 3003935 is based on an emergency call system with the subscriber devices sending the emergency call; a center receiving the emergency call and transmission of the emergency call via a dialing switching system, the subscriber device automatically dialing a connection to the emergency call center after triggering the emergency call and displaying an identifier sent by it.

It is also known to use an alarm and information system to spread objects, e.g. Monitor heating systems in order to carry out controls in accordance with the safety regulations with a minimum of personnel expenditure. The system parameters to be monitored are routed to a control center, evaluated, displayed if necessary and, in the event of impermissible deviations that require an alarm to be triggered, they are reported on via the public telephone network.

In the previously briefly explained alarm and information systems - as is generally the case - data acquisition is provided in a signaling center with relatively great effort. It is therefore the object of the invention to provide a burglar alarm system which works without the conventional alarm centers. The modules on offer for this technology are to be largely used. The false alarms occasionally triggered by radio technology should be avoided by using telephone lines for the transmission. Thus, a burglar alarm and alarm system should be brought onto the market with a comparatively simplified effort and thus cost-effectively. On the one hand, for cost reasons, on the other hand, it can be used variably according to the respective interests of the users, applications should be possible and expedient for broad sections of the population.
In relation to the different switching functions of the electromagnetic key switch, it is part of the object of the invention to inevitably only permit a one-speed closing movement when locking from the inside, which activates an intrusion detector, while motion detectors that activate additional entry areas, such as, are to be armed with a two-speed closing movement from the outside Secure windows accessible from below. It should also be ensured that no false alarm is triggered when the door is open.

• I. Es besteht die Aufgabe, den Eingangsbereich einer Wohnung zu überwachen. Die Eingangstür wird mit einem elektromagnetischen Schloß versehen. Dieses Schloß besitzt eine zusätzliche mechanische Verriegelung die verhindert, im geöffneten Zustand der Tür einen Fehlalarm auszulösen. Nur wenn die Tür geschlossen ist, also die Tür eingeklingt ist, läßt sich das Schloß scharf schalten. Ein eingebauter Mikrotaster im Schloß bewirkt bei 1- maligem Abschließen bei gewaltsamer Öffnung das Auslösen von Alarm durch einen Einbruchmelder, indem eine geschlossene Meldelinie unterbrochen wird. Weiterhin erfolgt die Absicherung des Schwachpunktes Balkon (oder sonstiger Einstiegsmöglichkeiten wie von unten erreichbare Fenster) über Bewegungsmelder oder passive Glasbruchmelder, die in die bestehende Schleife geschaltet sind. Dazu aktiviert ein weiterer Mikrotaster im Schloß beim 2- maligen Abschließen die Bewegungs- oder Glasbruchmelder. Das 2- malige Abschließen ist nur von außen möglich. Somit wurde eine Möglichkeit geschaffen, den Zwangspaß (Eingangstür) zu schützen, unabhängig davon, ob sich eine Person in der Wohnung befindet oder diese Wohnung verlassen wurde und außerdem bei verlassener Wohnung weitere gefährdete Bereiche in den Objektschutz einzubeziehen.
• II. Für die Wohnungen, die im Erdgeschoßbereich liegen und der gefährdete Einstiegsbereich mit Bewegungsmeldern abgesichert wird, ist die Installation eines Überfalltasters von Bedeutung. Der Nutzer hat die Möglickeit, wenn er sich in der Wohnung befindet, einen stillen Hilferuf zu senden. Der Überfalltaster kann in die bestehende Meldelinie eingebunden werden, es kann aber auch eine seperate Linie verwendet werden, um die Überfallmeldung von der Einbruchsmeldung unterscheiden zu können. Die Funktionstüchtigkeit der Überfalltaster ist unabhängig von der Scharfschaltung der Anlage.
• III. Für Wohnungen, in denen Hilfebedürftige, Behinderte und Schwerbehinderte wohnen, bieten die vorherigen Varianten größtmögliche Sicherheit.
  Es wird weiterhin vorgeschlagen, in diesen Wohnungen die Anlagen noch zu erweitern. Das digitale Weitermeldungsgerät wird zusätzlich mit einem Funkempfänger ausgerüstet. Dieser Empfänger wird mit dem Weitermeldungsgerät gekoppelt und über einen Notrufsender, den der Nutzer der Wohnung bei sich trägt, kann mittels Knopfdruck bei verschiedenen Situationen (Unfall, Anfall durch Krankheit, Brand usw.) in seinem Wohnungsbereich die automatisch-telefonische Alarmierung über Weitermeldungsgerät zu einem digitalen Empfangsgerät weitergeleitet werden.

According to the invention, the object is achieved as follows:
A digital relaying device and a digital receiving device with registration and evaluation are used as basic equipment for the overall system. The connection is made via a telephone line. The reporting lines of the relaying device are designed as differential loops and thus sabotage monitoring is granted, ie unauthorized interventions lead to the alarm being triggered. By assigning the reporting lines to the individual apartments, you can see in which apartment the burglary is taking place or from which apartment the emergency call is coming. The basic equipment also includes an electromechanical lock with micro pushbuttons for intrusion detectors and motion detectors, further security-related components, e.g. B. Panic button, emergency transmitter, and an emergency power supply that supplies the system for 60 hours in the event of a power failure. The width reporting device mentioned above is expediently installed next to the main telephone connection (usually in the basement area).
The further explanations are made by describing different variants of the alarm triggering. The key element is the electromechanical switch lock, in which important safety-related assemblies can be addressed via micro-switches. The detailed explanations for the structure of the key switch are made after the description of alarm variants explains how the key lock works within the overall concept.

• I. The task is to monitor the entrance area of an apartment. The entrance door is provided with an electromagnetic lock. This lock has an additional mechanical lock that prevents a false alarm from being triggered when the door is open. The lock can only be armed when the door is closed, i.e. when the door has snapped in. A built-in micro switch in the lock triggers an alarm by an intrusion detector when the door is locked once and is forcibly opened by interrupting a closed detection line. Furthermore, the weak point balcony (or other entry options such as windows accessible from below) is secured via motion detectors or passive glass break detectors that are connected to the existing loop. To do this, another micro switch in the lock activates the motion or glass break detector when it is locked twice. It can only be locked twice from the outside. Thus, an opportunity was created to protect the compulsory fun (entrance door), regardless of whether a person is in the apartment or has been left, and also to include other vulnerable areas in property protection when the apartment is abandoned.
• II. The installation of a panic button is important for the apartments that are located on the ground floor and the endangered entry area is secured with motion detectors. The user has the option to send a silent call for help when he is in the apartment. The panic button can be integrated into the existing alarm line, but a separate line can also be used to distinguish the panic report from the intrusion report. The function of the panic buttons is independent of the arming of the system.
• III. For apartments in which people in need, disabled and severely disabled people live, the previous variants offer the greatest possible security.
  It is also proposed to expand the facilities in these apartments. The digital relaying device is also equipped with a radio receiver. This receiver is connected to the relay device and via an emergency transmitter that the user of the apartment carries with him, at the push of a button in various situations (accident, attack due to illness, fire, etc.) in his home area, the automatic telephone alarm via relay device can be combined digital receiving device can be forwarded.

In any case, the electromagnetic switch lock is essential to the invention in the overall complex of apartment surveillance. The following explanations regarding the structure of the key switch make it clear that only the overall solution within the scope of the invention complex ensures the desired high protection effect.
The key switch consists of two basic assemblies, a box lock with an outer cylinder and an internal rotary knob, as well as the roller latch of a swing door lock. A locking linkage connects the two assemblies to one another and prevents that when the entrance door to the box lock is open, neither the outer cylinder nor the rotary knob can be erroneously moved by closing. As a result, the user is unable to operate the key switch when the entrance door is open and a false alarm is therefore excluded. When the door is open, the locking linkage blocks a toothed linkage in the box lock.
When the entrance door is closed, the roller latch is guided into the opposite side of the latch. This enables a closing movement of the toothed linkage and thus one or two pushes of the bolt from the box lock. Locking takes place with the outer cylinder or inside with the rotary knob whereby the bolt activates one or two micro buttons with a corresponding alarm loop.

The locking linkage already mentioned is firmly connected to the toothed linkage in the lower part of the key switch (box lock). The toothed linkage can be moved via drive bolts in such a way that the bolt locks or opens or opens the door once or twice. The drive bolts are moved by the outer cylinder or inside by the rotary knob. To realize the one-off locking from the inside, the toothed linkage is double and basically congruent. Accordingly, separate drive bolts that are accessible from the inside are also provided for the second toothed linkage. When the inner rotary knob is moved, a locking hook engages in a drive bolt that can be reached from the inside after the first closing movement has been carried out. The second locking movement is not possible due to the action of the locking hook. Only the first micro button is activated.
When locking and unlocking the door from the outside, the locking hook is deactivated by a release bolt.
In the following exemplary embodiment with a few variants, the overall complex is explained first, followed by the switch lock design.
Variants I to III previously described are shown in the drawings in accordance with FIGS. 1 to 4. It can be seen from the overview plan according to FIG. 5 that the arrangement of a distributor in the apartments takes into account the respective assemblies which correspond to the customer's requirements. As a result, the type of call and the corresponding apartment are assigned on the digital receiving device.

An einem Ausführungsbeispiel sollen die bisherigen Darlegungen nochmals erläutert werden. Es wird auf Variante II und Figur 3 Bezug genommen.
Der Nutzer der Wohnung schaltet das Schloß 6 bei geschlossener Tür scharf. Bei unbefugtem Eingriff an der Tür übernimmt der Einbruchsmelder 7 (ausgelöst durch einen Mikrotaster im Schaltschloß) das Auslösen von Alarm (Das Unterbrechen der geschlossenen Meldelinie löst über Weitermeldungsgerät I am digitalen Empfangsgerät 2 das Alarmsignal aus.)
Sollte z. B. über einen Balkon ein Überfall erfolgen, wird durch die Hilfe erwartende Person in der Wohnung ein stiller Notauf mittels Überfalltaster 10 abgesetzt. Wenn ein Einbruch bei Abwesenheit in der Wohnung erfolgt, ist durch das zweimalige Abschließen ein zweiter Mikrotaster im Schaltschloß im Zusammenwirken mit Bewegungs- oder passiven Glasbruchmeldern ebenfalls in der Lage, Alarm auszulösen.With reference to the previous explanations, the reference symbols used in FIGS. 1 to 4 represent:

• 1 digital relay device
• 2 digital receiver
• 3 telephone line
• 4 Power grid connection
• 5 Termination line
• 6 electromagnetic switch lock
• 7 intrusion detectors
• 8 panic buttons
• 9 motion detectors
• 10 panic buttons acc. Figure 3
• 11 emergency transmitters
• 12 radio receivers for emergency transmitters

The previous statements are to be explained again using an exemplary embodiment. Reference is made to variant II and FIG. 3.
The user of the apartment activates lock 6 when the door is closed. In the event of unauthorized intervention on the door, the intrusion detector 7 (triggered by a micro switch in the key switch) triggers the alarm (interrupting the closed detection line triggers the alarm signal via relay device I on digital receiver device 2).
Should z. B. a robbery is carried out on a balcony, a silent emergency stop is triggered by the panic button 10 by the person awaiting help. If there is a break-in while you are away, a second micro switch in the key switch in combination with motion or passive glass break detectors can also trigger an alarm by locking twice.

According to Figure 6 is in the lock case 13 with lock case bottom 14, the roller latch 15, the guide plate 18 with slot 23 and guide pin 19. The guide plate has the stop 33 for the locking linkage 17. The pressure spring 16 generates the counterpressure for the roller latch 15 when it snaps into the opposite side of the latch 35. Furthermore, the bolt 20 and the bolt guide plate 29 with an elongated hole 31 and guide bolt 30 are arranged in the lock case 13. The toothed linkage 28 is fastened in a radially movable manner to the bearing 27 in such a way that the bolt 20 can be pushed into the first or second closed position by the drive bolts 34/1 and 34/2. The drive bolts 34/1 and 34/2 are mounted on a common rotatably mounted plate. The drive bolts 34/1 and 34/2 are changed in position by rotating the common plate and, for example, during the first closing movement in such a way that the drive bolt 34/2 snaps into the initially free tooth gap when the toothed linkage 28 is displaced. The spring 26 generates the counter pressure for the toothed linkage 28 in the initial or the first or second closed position.

Closing takes place with an outer cylinder or from the inside with a rotary knob, with the bolt 20 actuating one or two micro buttons 21, 22 depending on the closed position (micro button 21 for the entrance area, micro button 22 for motion detectors in vulnerable entry areas, such as windows accessible from below). When the micro button is activated 22 the user must be sure that nobody is in the apartment anymore, otherwise a false alarm can be triggered.

The locking linkage 17 prevents a false alarm when the door is open, since the toothed linkage 28 and thus bolt 20 cannot be moved.

In order to be able to move the bolt 20 from the inside only with one turn (only for activating the microswitch 21), the toothed linkage 28 is designed to be double and basically congruent and, as previously described, arranged radially movably on the bearing 27. This toothed linkage 28, which can only be reached from the inside, includes two drive bolts 34/1 and 34/2 which can only be reached from the inside.

(The double congruent arrangement of the toothed linkage 28 and the drive bolts 34/1 and 34/2, which can only be reached from the inside and are in the starting position in the same axis as the drive bolts 34/1 and 34/2 that can be reached from the outside, are shown in the drawing not shown).
The toothed linkage 28, which can be reached from the inside, is blocked by a locking hook 25 after a single-speed closing movement, by the locking hook 25 engaging in the drive bolt 34/2 when it locks into the previously free tooth space of the toothed linkage 28 due to the closing movement. A double closing from the inside is therefore not possible. When unlocking, the unlocking bolt 24 (which is fastened on the bolt guide plate 29) takes effect by pressing the locking hook 25 into the unlocking position (to the left as shown in the figure). The counter pressure for this is generated by the compression spring 32.

When locking via the outer cylinder, the drive bolts 34/1 and 34/2, which are accessible from the inside, are not rotated and therefore the locking hook 25 is also not effective.

In conclusion, it should be noted that the invention represents a technical solution in the overall complex, in which partly known assemblies and new assemblies in the design ensure a very effective protection of objects and people, and a false alarm is fundamentally prevented by incorrect operation.
