Description

Die Erfindung betrifft eine Vorrichtung zur Befestigung von Komponenten von Alarmanlagen nach dem Oberbegriff des Anspruches 1.The invention relates to a device for fastening components of alarm systems according to the preamble of claim 1.

Alarmanlagen beinhalten Komponenten zur Überwachung einzelner Bereiche, beispielsweise Sensoren an Zugangstüren, Fenstern usw., die von der Alarmzentrale abgesetzt sind. Diese Sensoren sind üblicherweise in Gehäusen angeordnet und an entsprechenden Stellen, meist Wänden, befestigt. Die Befestigung erfolgt bei bekannten Komponenten so, daß die Befestigungselemente, beispielsweise Schrauben, bei vollständig montierter Komponente nicht zugänglich sind. Zu diesem Zweck ist es notwendig, das Gehäuse bei der Montage zu öffnen und das montierte, geschlossene Gehäuse gegen ein Öffnen zu sichern.Alarm systems contain components for monitoring individual areas, such as sensors on access doors, windows, etc., which are remote from the alarm center. These sensors are usually arranged in housings and attached to appropriate locations, usually walls. In the case of known components, the fastening takes place in such a way that the fastening elements, for example screws, are not accessible when the component is fully assembled. For this purpose, it is necessary to open the housing during assembly and to secure the assembled, closed housing against opening.

Der Erfindung liegt die Aufgabe zugrunde, in einem Gehäuse angeordnete Komponenten von Alarmanlagen so auszugestalten, daß die Befestigung schnell und ohne Öffnen des Gehäuses erfolgen kann, wobei die Komponenten gegen Sabotage geschützt sind.The invention has for its object to design arranged in a housing components of alarm systems so that the attachment can be done quickly and without opening the housing, the components being protected against sabotage.

Diese Aufgabe wird, ausgehend von den Merkmalen des Oberbegriffes des Anspruches 1 durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved on the basis of the features of the preamble of claim 1 by the characterizing features of claim 1. Advantageous embodiments of the invention are specified in the dependent claims.

Gemäß der Erfindung weist die Gehäuserückwand eine Aussparung auf, durch die ein Befestigungsmittel, beispielsweise eine Schraube geführt werden kann. Innerhalb des Gehäuses ist eine Anordnung zur Überwachung der Position des Befestigungsmittels angeordnet, die insbesondere eine Positionsänderung des Befestigungsmittels innerhalb des Gehäuses erkennt und ein Alarmsignal liefert, das vorzugsweise an die Alarmzentrale weitergeleitet wird.According to the invention, the rear wall of the housing has a recess through which a fastening means, for example a screw, can be guided. Arranged within the housing is an arrangement for monitoring the position of the fastening means, which in particular detects a change in position of the fastening means within the housing and supplies an alarm signal which is preferably forwarded to the alarm center.

Durch die erfindungsgemäße Vorrichtung ist eine einfache Anbringung von Komponenten einer Alarmanlage möglich, indem das Gehäuse mittels der Aussparung in das Befestigungsmittel eingehängt werden kann. Als Befestigungsmittel können Schrauben oder Haken verwendet werden, die beispielsweise in einer Wand verankert sind. Das Befestigungsmittel ist dabei nicht zugänglich, da beispielsweise der Schraubenkopf oder der Haken in das Innere des Gehäuses ragen. Dort ist eine Anordnung zur Überwachung der Position des Befestigungsmittels angeordnet. Bei einer Änderung der Position oder der Abnahme des Gehäuses vom Befestigungsmittel wird ein Alarmsignal ausgegeben, so daß eine unbefugte Entfernung der Komponente nicht möglich ist.The device according to the invention enables components of an alarm system to be attached in a simple manner by the housing being able to be suspended in the fastening means by means of the cutout. Screws or hooks that are anchored in a wall, for example, can be used as fastening means. The fastener is not accessible because, for example, the screw head or the hook protrude into the interior of the housing. An arrangement for monitoring the position of the fastening means is arranged there. When the position or the removal of the housing from the fastening means changes, an alarm signal is issued so that an unauthorized removal of the component is not possible.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung besteht die Anordnung zur Überwachung der Position des Befestigungsmittels aus einem Schalter, der bei Durchführung des Befestigungsmittels durch die Aussparung betätigt wird. Dadurch wird auf einfache und kostengünstige Weise die Position, insbesondere das Vorhandensein des Befestigungsmittels im Gehäuse überwacht. Sobald das Befestigungsmittel aus dem Gehäuse entfernt wird, d.h. bei Abnahme des Gehäuses vom Befestigungsort, wird der Schalter wieder geöffnet bzw. er ändert seinen Zustand, was zur Alarmauslösung führt. Fehlalarme können dadurch vermieden werden, daß der Schalter so angeordnet bzw. so ausgeführt wird, daß eine geringe Bewegung nicht zu einer Schalterbetätigung führt.According to an advantageous embodiment of the invention, the arrangement for monitoring the position of the fastening means consists of a switch which is actuated by the recess when the fastening means is carried out. As a result, the position, in particular the presence of the fastening means in the housing, is monitored in a simple and inexpensive manner. Once the fastener is removed from the housing, i.e. when the housing is removed from the mounting location, the switch is opened again or changes its state, which triggers the alarm. False alarms can be avoided by arranging the switch or executing it in such a way that a slight movement does not lead to a switch actuation.

Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, daß die Anordnung zur Überwachung der Position des Befestigungsmittels mittelbar oder unmittelbar an der Innenseite der Gehäusevorderwand angeordnet ist. Bei Öffnen des Gehäuses verändert sich die relative Position der Positionsüberwachungsanordnung zum Befestigungsmittel und es wird ein Öffnen des Gehäuses erkannt und führt zur Alarmgabe.A further advantageous embodiment of the invention provides that the arrangement for monitoring the position of the fastening means is arranged indirectly or directly on the inside of the front wall of the housing. When the housing is opened, the relative position of the Position monitoring arrangement for the fastener and an opening of the housing is recognized and leads to an alarm.

Im weiteren hat es sich als vorteilhaft erwiesen, das Gehäuse so auszuführen, daß es nur im nicht befestigten Zustand geöffnet werden kann. Dies kann beispielsweise erreicht werden, indem die Schrauben, welche die Gehäuseteile zusammenhalten, nur von der Gehäuserückwand zugänglich sind.Furthermore, it has proven to be advantageous to design the housing so that it can only be opened when it is not fastened. This can be achieved, for example, by only accessing the screws that hold the housing parts together from the rear wall of the housing.

Im folgenden wird die Erfindung an Hand eines Ausführungsbeispiels gemäß den Figuren 1 und 2 erläutert.
Es zeigen:

Das Gehäuse, in dem eine Komponente einer Alarmanlage, beispielsweise ein Sensor für Raumüberwachung, der in der Figur nicht dargestellt ist, angeordnet ist, besteht aus einer Gehäuserückwand 2 und einer Gehäusevorderwand 3, die mittels einer Schraube 4 verbunden sind.
Die Gehäuserückwand 2 weist eine Aussparung 21, 22 auf, durch die ein Befestigungsmittel 8, im vorliegenden Fall eine Schraube, hindurchgeführt werden kann.
Wie aus Figur 2 ersichtlich, weist die Aussparung 21, 22 einen unteren Teil 22, dessen Durchmesser größer ist als der Kopf der hindurchzuführenden Schraube 8 ist, und einen oberen Teil 21 auf, dessen Durchmesser kleiner als der Schraubenkopf und größer als der Durchmesser des Schaftes des Schraube 8 ist.
Die Schraube 8 ist beispielsweise in eine Wand 1 eingeschraubt, wobei der Schraubenkopf einen Abstand zur Wand 1 aufweist. Das Gehäuse 2, 3 wird an der Schraube befestigt, indem der untere Teil 22 der Aussparung über den Kopf der Schraube 8 geführt wird und anschließend das Gehäuse abgesenkt wird, so daß der Schaft der Schraube 8 im Bereich des oberen Teils 21 der Aussparung liegt.
Im Inneren des Gehäuses ist gemäß dem Ausführungsbeispiel ein Schalter 6 mit einer Schaltzunge 61 angeordnet. Der Schalter ist innerhalb des Gehäuses so angeordnet, daß bei Einhängen des Gehäuses der Kopf der Schraube die Schalterzunge 61 betätigt. Bei Abnahme des Gehäuses durch einen Unbefugten wird ein Alarmsignal ausgegeben.
Dabei wird vorzugsweise ein entsprechendes Signal an die Alarmzentrale gegeben. Im Fall der Abnahme des Gehäuses durch den Benutzer kann ein Alarm unterdrückt werden, indem die Alarmanlage ganz oder nur die Komponente betreffend unscharfgeschaltet wird.The housing, in which a component of an alarm system, for example a sensor for room monitoring, which is not shown in the figure, is arranged, consists of a housing rear wall 2 and a housing front wall 3, which are connected by means of a screw 4.
The housing rear wall 2 has a recess 21, 22 through which a fastening means 8, in the present case a screw, can be passed.
As can be seen from FIG. 2, the recess 21, 22 has a lower part 22, the diameter of which is larger than the head of the screw 8 to be passed, and an upper part 21, the diameter of which is smaller than the screw head and larger than the diameter of the shaft the screw 8 is.
The screw 8 is screwed, for example, into a wall 1, the screw head being at a distance from the wall 1. The housing 2, 3 is fastened to the screw by passing the lower part 22 of the recess over the head of the screw 8 and then lowering the housing so that the shaft of the screw 8 lies in the region of the upper part 21 of the recess.
According to the exemplary embodiment, a switch 6 with a switching tongue 61 is arranged inside the housing. The switch is arranged within the housing so that the head of the screw when hanging the housing Switch tongue 61 actuated. If the housing is removed by an unauthorized person, an alarm signal is issued.
A corresponding signal is preferably sent to the alarm center. If the housing is removed by the user, an alarm can be suppressed by disarming the alarm system entirely or only regarding the component.

Der Schalter 6, 61 kann entweder direkt an der Gehäusevorderwand angebracht sein oder, falls die Abmessungen des Gehäuses dies nicht zulassen, mittels eines Einsatzes 7 und einem Befestigungsmittel 5 mit der Gehäusevorderwand verbunden sein.The switch 6, 61 can either be attached directly to the front wall of the housing or, if the dimensions of the housing do not allow this, be connected to the front wall of the housing by means of an insert 7 and a fastening means 5.

Durch die erfindungsgemäße Vorrichtung können Komponenten einer Alarmanlage schnell und damit kostengünstig angebracht und beispielsweise für Servicezwecke entfernt werden, wobei der Schutz gegen eine unberechtigte Entfernung der Komponente gegenüber bekannten Lösungen noch erhöht wurde.The device according to the invention allows components of an alarm system to be attached quickly and therefore inexpensively and removed, for example, for service purposes, the protection against unauthorized removal of the component being increased compared to known solutions.
