Description

Die Erfindung bezieht sich auf eine Verbindungseinrichtung für automatische Brandmelder, die einen mit einer Melderfassung zu verbindenden Meldersockel aufweist.The invention relates to a connection device for automatic fire detectors, which has a detector base to be connected to a detector.

Automatische Brandmelder weisen im allgemeinen einen Sockel auf, in den der eigentliche Melder eingesetzt und beispielsweise mit einem Bajonettverschluss verankert wird. Bei der Aufputzmontage wird dabei eine Schutzhülse, die z.B. aus Plastikmaterial gefertigt sein kann, zum Teil über den Melder und über den Sockel geschoben und mit einer oder zwei Schrauben arretiert. Bei der Unterputzmontage ist der Meldersockel in einer in der Decke eingebrachten Einlassdose installiert. Dabei wird der Sockel und die Einlassdose bei eingesetztem Melder mit einer Rosette abgedeckt und ebenfalls mit Schrauben befestigt.Automatic fire detectors generally have a base in which the actual detector is inserted and anchored, for example, with a bayonet catch. During surface mounting, a protective sleeve is used, e.g. can be made of plastic material, partly pushed over the detector and over the base and locked with one or two screws. For flush mounting, the detector base is installed in an inlet box installed in the ceiling. When the detector is inserted, the base and the inlet socket are covered with a rosette and also fastened with screws.

Aus der Europäischen Patentanmeldung Nr. 014251 ist eine Verbindungseinrichtung für Brandmelder bekannt. Dort ist eine Verbindungseinrichtung beschrieben, bei der über elektrische und mechanische Verbindungsorgane eine Verbindung zwischen einem Sockelteil und einem Meldereinsatz eines Brandmelders hergestellt wird. Dabei sind der Sockelteil und der Melderteil aufeinander abgestimmt, so dass ein anderer Meldereinsatz mit dem bekannten Sockelteil nicht verbindbar ist.A connection device for fire detectors is known from European Patent Application No. 014251. There, a connection device is described in which a connection between a base part and a detector insert of a fire detector is established via electrical and mechanical connection elements. The base part and the detector part are matched to one another, so that another detector insert cannot be connected to the known base part.

Neuere und modernere Melder sind mittlerweile funktionstüchtiger, aber auch kleiner als bekannte Melder. Sie weisen einen kleineren Durchmesser und eine geringere Bauhöhe auf, so dass auch kleinere und anders gestaltete Meldersockel bzw. Melderfassungen erforderlich sind. Um vorhandene Brandmeldeanlagen mit modernen leistungsfähigeren Meldern und mit einer entsprechenden, neu konzipierten Zentrale ausrüsten zu können, müsste jeder Melderplatz für die Melder neuerer und modernerer Bauart umgerüstet werden. Das heisst, es müssten die alten Meldersockel abmontiert und neue Meldersockel installiert werden. Dies bringt aber einerseits die Gefahr mit sich, dass dabei leicht die vorhandenen Installationsdrähte beschädigt werden können und dann eine neue, aufwendige und kostenintensive Neuinstallation notwendig werden könnte. Andererseits ist das Abmontieren der alten Meldersockel und das Anmontieren der neuen Meldersockel sehr aufwendig. Ferner entstehen dann an der Decke freiwerdende unschöne Ränder am Melderplatz für die ursprünglichen Melder, weil die neuen Meldertypen einen Sockel mit kleinerem Durchmesser besitzen. Bei der Unterputzmontage würden die Melder neuer Bauart mit geringerer Bauhöhe in den Einlassdosen zu tief sitzen, wenn nicht für die Einlassdosen ein eigener speziell zu konzipierender Sockel dafür vorgesehen wird.Newer and more modern detectors are now more functional, but also smaller than known detectors. They have a smaller diameter and a lower overall height, so that smaller and differently designed detector bases or detector holders are also required. In order to be able to equip existing fire alarm systems with modern, more powerful detectors and with a corresponding, newly designed control center, every detector location would have to be converted for detectors of newer and more modern designs. This means that the old detector bases would have to be removed and new detector bases installed. On the one hand, however, this entails the risk that the existing installation wires can easily be damaged and a new, complex and costly new installation may then be necessary. On the other hand, dismantling the old detector base and fitting the new detector base is very complex. Furthermore, unsightly edges on the detector area for the original detectors are released on the ceiling, because the new detector types have a base with a smaller diameter. In the case of flush mounting, the detectors of a new design with a lower overall height would sit too deep in the inlet sockets if a separate base to be specially designed for the inlet sockets is not provided.

Um all diese Nachteile zu vermeiden, ist es Aufgabe der Erfindung, eine Verbindungseinrichtung der eingangs genannten Art so auszugestalten, dass sie ohne grossen Aufwand auf bereits vorhandene Meldersockel aufgesetzt und befestigt werden kann und dass darauf eine Melderfassung für verschiedene Meldertypen bzw. Meldereinsätze neuerer Bauart montiert werden kann. Dabei soll die Verbindungseinrichtung als Massenprodukt in einfacher Weise gefertigt und mit wenigen Handgriffen montiert werden können.In order to avoid all these disadvantages, it is an object of the invention to design a connecting device of the type mentioned at the outset in such a way that it can be fitted and attached to existing detector bases with little effort and that a detector holder for different detector types or detector inserts of a more recent type is mounted thereon can be. The connecting device should be mass-produced in a simple manner and be assembled in a few simple steps.

Diese Aufgabe wird erfindungsgemäss mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.This object is achieved according to the invention with the characterizing features of claim 1.

Der erfindungsgemässe Adapter ist als kreisscheibenförmiges Kunststoffspritzteil ausgebildet und weist beispielsweise zwei Befestigungsschrauben auf, die durch im Adapter so angeordnete Befestigungsöffnungen gesteckt sind, dass der Adapter auf den alten, vorhandenen Meldersockel im dortigen Gewinde schnell montiert werden kann. Zum anderen besitzt der Adapter eine oder mehrere Aufnahmevorrichtungen für Befestigungselemente, z.B. Schrauben, mit denen eine Melderfassung für moderne automatische Brandmelder angeschraubt werden kann. Zweckmässigerweise ist diese Aufnahmevorrichtung entsprechend der Befestigungslöcher der Melderfassung am Adapter angeordnet. Diese Aufnahmevorrichtung kann in einfacher Weise als eine zylinderförmige Anformung mit einer mittig angebrachten Bohrung ausgebildet sein, in die zur Montage der Melderfassung eine Schraube mit Schneidgewinde eingedreht werden kann. Um die neue Melderfassung elektrisch mit dem alten Meldersockel zu verbinden, weist der Adapter einen Durchbruch auf, durch den die an beiden Enden mit Kabelschuhen versehenen Verbindungsleitungen (Kabelstücke) gesteckt und an den Schraubklemmen des Meldersockels bzw. der Melderfassung angeschraubt werden können.The adapter according to the invention is designed as a circular plastic injection molded part and has, for example, two fastening screws which are inserted through fastening openings arranged in the adapter such that the adapter can be quickly mounted on the old, existing detector base in the thread there. On the other hand, the adapter has one or more holding devices for fastening elements, e.g. Screws with which a detector holder for modern automatic fire detectors can be screwed on. This receiving device is expediently arranged on the adapter in accordance with the fastening holes of the detector detection. This receiving device can be designed in a simple manner as a cylindrical projection with a centrally arranged bore into which a screw with a cutting thread can be screwed in for mounting the detector holder. In order to electrically connect the new detector socket to the old detector base, the adapter has a breakthrough through which the connecting lines (cable pieces) provided with cable lugs can be inserted and screwed to the screw terminals of the detector base or the detector socket.

Weitere Einzelheiten und verschiedene Ausführungsformen der Erfindung ergeben sich aus den Unteransprüchen und werden im folgenden anhand der Zeichnung näher erläutert. Dabei zeigen:

  • Fig. 1 einen automatischen Brandmelder mit dem neuerungsgemässen Adapter für einen auf Putz montierten Meldersockel und
  • Fig. 2 einen automatischen Brandmelder mit dem neuerungsgemässen Adapter für einen unter Putz montierten Meldersockel.
Further details and various embodiments of the invention result from the subclaims and are explained in more detail below with reference to the drawing. Show:
  • Fig. 1 shows an automatic fire detector with the new adapter for a plaster mounted detector base and
  • Fig. 2 shows an automatic fire detector with the new adapter for a flush-mounted detector base.

In Fig. 1 ist ein automatischer Brandmelder 3 dargestellt, der mit seiner Melderfassung 13 auf dem neuerungsgemässen Adapter 1 und dieser auf dem alten Meldersockel 4 montiert ist. Dabei sind der Adapter 1 und die Melderfassung 13 teilweise aufgerissen dargestellt, so dass der Sockel 4 bekannter Melder, der Adapter 1 und die Melderfassung 13 teilweise im Schnitt gezeigt sind.In Fig. 1, an automatic fire detector 3 is shown, which is mounted with its detector 13 on the new adapter 1 and this on the old detector base 4. The adapter 1 and the detector holder 13 are shown partially torn open, so that the base 4 of known detectors, the adapter 1 and the detector holder 13 are shown partly in section.

Der alte Meldersockel 4 ist an der Decke 2 befestigt. Die unter Putz geführten Installationsleitungen 5 sind aus der Decke 2 herausgeführt und im allgemeinen durch Dichtungen 4b im Meldersockel 4 zu den Schraubklemmen 7 geführt und dort angeschlossen. Der Sockel 4 weist zwei Schraubgewinde 4a auf, die im Sockel 4 eingelassen sind. In der Fig. 1 ist lediglich ein Schraubgewinde, auf der linken Seite, mit 4a angedeutet. In dieses Schraubgewinde 4a wurde, nachdem der Melder alter Bauart in den Sockel eingestreckt und die eingangs erwähnte Schutzhülse aufgesteckt wurde, die Schutzhülse mit ein oder zwei Schrauben befestigt. Das Schraubgewinde 4a wird für die Befestigung des neuerungsgemässen Adapters 1 verwendet.The old detector base 4 is attached to the ceiling 2. The plastered installation lines 5 are led out of the ceiling 2 and generally through seals 4b in the detector base 4 to the screw terminals 7 and connected there. The base 4 has two screw threads 4a, which are embedded in the base 4. In Fig. 1, only a screw thread, on the left side, is indicated by 4a. In this screw thread 4a, after the old design detector was inserted into the base and the protective sleeve mentioned at the beginning was attached, the protective sleeve was fastened with one or two screws. The screw thread 4a is used for fastening the adapter 1 according to the innovation.

Der kreisscheibenförmig ausgebildete Adapter 1 weist einen am äusseren Rand angeformten Kegelmantel 1a auf, der an der Decke 2 aufliegt und den Sockel 4 umschliesst. Der Durchmesser des Kegelmantels 1 des Adapters 1 ist dabei im Bereich der Decke 2 grösser als der Durchmesser des Meldersockels 4. In der Nähe des Aussenrandes des Adapters 1 ist senkrecht zur Kreisfläche des Adapters 1 diametral gegenüberliegend jeweils ein Zylindermantel 12a angeformt. In der Fig. 1 ist nur der linke Zylindermantel 12a dargestellt. Im Zylinderinneren ist eine, z.B. unverlierbare, Schraube 12 geführt, die durch die Befestigungsöffnung 12b gesteckt ist. Mit beiden Schrauben 12 ist der Adapter 1 auf dem Sockel 4 im Schraubgewinde 4a befestigt.The circular disc-shaped adapter 1 has a conical shell 1a formed on the outer edge, which lies on the ceiling 2 and surrounds the base 4. The diameter of the conical jacket 1 of the adapter 1 is larger in the area of the ceiling 2 than the diameter of the detector base 4. In the vicinity of the outer edge of the adapter 1, a cylindrical jacket 12a is formed diametrically opposite each other perpendicular to the circular surface of the adapter 1. In Fig. 1 only the left cylinder jacket 12a is shown. Inside the cylinder is e.g. captive, screw 12, which is inserted through the mounting opening 12b. The adapter 1 is fastened on the base 4 in the screw thread 4a with two screws 12.

Auf dem Adapter 1 ist die Fassung 13 für neuere Meldertypen 3 mit zwei Schrauben 15 befestigt. Dabei ist der Durchmesser des kreisscheibenförmigen Adapterkörpers 1 grösser als der Durchmesser der Melderfassung 13. In der Zeichnung ist nur die linke Schraube 15 für die Befestigung der Melderfassung 13 auf dem Adapter 1 dargestellt. Zu diesem Zweck ist senkrecht zur Adapterkreisfläche 1, zur Deckenseite 2 hin eine zylinderförmige Anformung 16 mit einer mittig angeordneten Bohrung 16a am Adapter 1 und in der Melderfassung 13 ein Befestigungsloch 15a angebracht. Die zwei Schrauben 15 können Blechschrauben sein, die sich in die Bohrung 16a des Adapters 1 einschneiden, so dass kein zusätzliches Gewinde im Adapter 1 oder eine eigene Mutter erforderlich ist. Der Adapter 1 weist einen Durchbruch 11 auf, durch den vorgefertigte Kabelstücke 9 (nur eines dargestellt) durchgeführt sind, um die elektrische Verbindung von den Schraubklemmen 7 des Meldersockels 4 zu den Schraubklemmen 14 der Melderfassung 13 herzustellen. Zur schnelleren Montage sind an den Kabelenden Kabelschuhe 8 und 9a angebracht. In die Melderfassung 13 ist der Meldereinsatz 3 in an sich bekannter Weise eingesetzt.The socket 13 for newer detector types 3 is fastened on the adapter 1 with two screws 15. The diameter of the circular disc-shaped adapter body 1 is larger than the diameter of the detector holder 13. In the drawing, only the left screw 15 for fastening the detector holder 13 on the adapter 1 is shown. For this purpose, perpendicular to the adapter circular surface 1, towards the ceiling side 2, a cylindrical projection 16 with a centrally arranged bore 16a is attached to the adapter 1 and a fastening hole 15a in the detector socket 13. The two screws 15 can be self-tapping screws which cut into the bore 16a of the adapter 1, so that no additional thread in the adapter 1 or a separate nut is required. The adapter 1 has an opening 11 through which prefabricated cable pieces 9 (only one shown) are passed in order to establish the electrical connection from the screw terminals 7 of the detector base 4 to the screw terminals 14 of the detector socket 13. Cable lugs 8 and 9a are attached to the cable ends for faster installation. The detector insert 3 is inserted into the detector holder 13 in a manner known per se.

In Fig. 2 ist ein automatischer Brandmelder mit einem Adapter 1' für die Unterputzmontage dargestellt. In der Einlassdose 6 ist ein an sich bekannter Meldersockel 4' für Einlassdosen dargestellt. Dabei sind in der Fig. 2 die Montagemöglichkeiten für zwei Melderfassungen 13 und 13' für unterschiedliche Meldertypen abgebildet.In Fig. 2 an automatic fire detector with an adapter 1 ' for flush mounting is shown. In the inlet box 6, a known detector base 4 'for inlet boxes is shown. The mounting options for two detector sockets 13 and 13 ' for different detector types are shown in FIG. 2.

In der Decke 2 sitzt die Einlassdose 6 mit dem bekannten Unterputzsockel 4' für Melder 3' alter Bauart. Am Boden der Einlassdose 6 befindet sich eine Sperrfeder 6a; die Leitungsinstallation 5 gemäss Fig. 1 ist nicht mehr eigen gezeigt. An den Schraubklemmen 7 am Meldersockel 4' sind die Verbindungsleitungen 9 mit jeweils einem Kabelschuh 8 angeklemmt. In der Zeichnung ist nur ein Kabelstück 9 dargestellt. Der neuerungsgemässe Adapter 1' weist eine vom Adapter 1 nach Fig. 1 abweichende Bauform auf. Der Adapter 1' ist ein kreisscheibenförmiges Spritzteil mit einem Durchmesser, der grösser als der Durchmesser beim Adapter 1 für die Aufputzversion ist. Der Durchmesser des Adapters 1' ist dabei grösser als der Durchmesser der Einlassdose 6, so dass diese vom Adapter 1' überdeckt ist. Im Gegensatz zu Fig. 1 fehlt der Kegelmantel (1a). Am Kreisrand des Adapters 1' ist zur Deckenseite 2 hin ein ringförmiger Wulst 1 b angeformt, so dass der Adapter 1' auf der Decke 2 aufliegt. Die Anformung 16 mit der Bohrung 16a entspricht der Anformung des Adapters 1 nach Fig. 1 und ist deckungsgleich mit dem Befestigungsloch 15a in der Melderfassung 13 bzw. 13' für beispielsweise den Melder 3. Ebenso ist die Blechschraube 15 zur Befestigung der Melderfassung 13 bzw. 13' auf dem Adapter 1' dargestellt. Der Adapter 1' weist ebenfalls einen Durchbruch 11 für die Verbindungskabel 9 auf. Diese sind mit den Kabelschuhen 9a an den Schraubklemmen 14 der Melderfassung 13 bzw. 13' befestigt.In the ceiling 2 sits the inlet box 6 with the known flush-mounted base 4 'for detectors 3' of old design. At the bottom of the inlet box 6 there is a locking spring 6a; 1 is no longer shown on its own. The connecting lines 9 are each clamped to the screw terminals 7 on the detector base 4 ', each with a cable lug 8. In the drawing, only one piece of cable 9 is shown. The adapter 1 'according to the innovation has a different construction from the adapter 1 according to FIG. 1. The adapter 1 'is a circular disk-shaped molded part with a diameter that is larger than the diameter of the adapter 1 for the surface-mounted version. The diameter of the adapter 1 'is larger than the diameter of the inlet socket 6, so that it is covered by the adapter 1'. In contrast to Fig. 1, the cone jacket (1a) is missing. At the circular edge of the adapter 1 'an annular bead 1 b is formed on the ceiling side 2, so that the adapter 1' rests on the ceiling 2. The projection 16 with the bore 16a corresponds to the projection of the adapter 1 according to FIG. 1 and is congruent with the mounting hole 15a in the detector socket 13 or 13 'for example for the detector 3. Likewise, the self-tapping screw 15 for fastening the detector socket 13 or 13 'shown on the adapter 1'. The adapter 1 'also has an opening 11 for the connecting cable 9. These are fastened to the screw terminals 14 of the detector socket 13 or 13 'with the cable lugs 9a.

Die Befestigungsvorrichtung für den Adapter 1' auf dem Sockel 4' ist gegenüber dem ersten Ausführungsbeispiel (Fig. 1) etwas anders gestaltet. Im Adapter 1' sind zwei Bohrungen 12b angeordnet. Davon ist nur eine gezeigt. Mit Befestigungsschrauben 12 wird der Adapter 1' am Sokkel 4' befestigt. Dazu sind im Sockel 4' an der vorhandenen Befestigungsvorrichtung 4'a lediglich jeweils eine Gewindeplatte 12c einzufügen. In der Fig. 2 ist sowohl ein Meldeeinsatz 3 neuerer Bauart als auch ein Meldeeinsatz 3' alter Bauart dargestellt. Dies dient nur zur Veranschaulichung. Entweder ist eine Melderfassung 13 für den Meldeeinsatz 3 oder eine Melderfassung 13' für einen hier nicht dargestellten Meldeeinsatz anderer Bauart vorgesehen.The fastening device for the adapter 1 'on the base 4' is designed somewhat differently from the first exemplary embodiment (FIG. 1). Two bores 12b are arranged in the adapter 1 '. Only one is shown. The adapter 1 'is fastened to the base 4' with fastening screws 12. For this purpose, only a threaded plate 12c is to be inserted into the base 4 'on the existing fastening device 4'a. 2 shows both a reporting insert 3 of a newer type and a reporting insert 3 'of the old type. This is for illustration only. Either a detector socket 13 for the detector insert 3 or a detector socket 13 'is provided for a detector insert of a different type, not shown here.

Mit Hilfe des neuerungsgemässen Adapters, der für die Montage Aufputz oder Unterputz ausgeführt sein kann, ist ein leichtes und schnelles Umrüsten einer vorhandenen Brandmeldeanlage möglich, ohne eine neue Installation vorsehen zu müssen. Es ist auch nicht notwendig, die vorhandenen ursprünglichen Meldersockel auszutauschen. Damit vermeidet man die Gefahr der Beschädigung der vorhandenen Verkabelung. Es ist lediglich der neuerungsgemässe Adapter auf die vorhandenen Sockel zu montieren und darauf mit einfachen Mitteln die Fassung für die verschiedenen neuen Meldertypen anzubringen. Es ist nur noch erforderlich, Verbindungsleitungen, die durch eine Öffnung im Adapter geführt sind, an den Schraubklemmen des alten Sockels anzuschrauben und mit den Schraubklemmen der neuen Melderfassung zu verbinden. Dies hat den Vorteil, dass eine schon bestehende Brandmeldeanlage ohne grossen Aufwand auf eine moderne Meldeanlage umgerüstet werden kann, in der neuzeitliche Melder und eine leistungsfähigere Zentrale verwendet werden können.With the help of the new adapter, which can be surface-mounted or flush-mounted, an existing fire alarm system can be easily and quickly converted without having to provide a new installation. It is also not necessary to replace the original detector base. This avoids the risk of damage to the existing wiring. All that needs to be done is to mount the adapter according to the innovation on the existing base and then use simple means to mount the socket for the various new detector types. It is only necessary to screw connecting cables that are passed through an opening in the adapter to the screw terminals of the old base and to connect them to the screw terminals of the new detector. This has the advantage that an existing fire alarm system can be converted to a modern alarm system in which modern detectors and a more powerful control center can be used.
