Description

Die Erfindung bezieht sich auf einen Handgefahrenmelder gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a manual hazard detector according to the preamble of claim 1.

In Gefahrenmeldeanlagen für Feuer- oder Polizeinotruf werden neben automatischen Meldern auch Melder für eine manuelle Betätigung, nämlich Handgefahrenmelder, sogenannte "Druckknopfmelder" verwendet. Derartige Melder werden üblicherweise in zwei Ausführungen hergestellt. Der Meldertyp B stellt eine indirekte Betätigung, eine sogenannte Druckknopfausführung dar. Dabei ist eine Glasscheibe einzuschlagen und dann der Druckknopf zu drücken, d.h. das Auslöseelement ist der Knopf (Bedienelement). Beim Meldertyp A für eine direkte Betätigung, eine sogenannte Springknopfausführung, muß lediglich die Glasscheibe eingeschlagen werden, dann springt der Knopf durch Federdruck heraus, d.h. das Auslöseelement ist von der Scheibe (zerbrechliches Element) plus dem Knopf (Bedienelement) gebildet. In beiden Fällen wird durch die Knopfbewegung ein elektrischer Schalter betätigt, welcher die Alarmmeldung als elektrisches Signal an die Gefahrenmeldeanlage weiterleitet. Dabei ist es außerordentlich wichtig, daß diese Melder einwandfrei funktionieren und jederzeit für eine sichere Alarmgabe einsatzbereit sind.In danger alarm systems for fire or police emergency calls, not only automatic detectors but also detectors for manual actuation, namely manual danger detectors, so-called "push-button detectors" are used. Such detectors are usually manufactured in two versions. The detector type B is an indirect actuation, a so-called push button version. A glass pane must be broken in and the push button pressed, i.e. the trigger element is the button (control element). With detector type A for direct actuation, a so-called spring button version, all you have to do is push in the glass pane, then the button pops out by spring pressure, i.e. the release element is formed by the disc (fragile element) plus the button (control element). In both cases, an electric switch is actuated by the push of a button, which forwards the alarm message as an electrical signal to the hazard alarm system. It is extremely important that these detectors function properly and are always ready for a safe alarm.

Bei dem bekannten Druckknopfmelder (Typ B) wird nach dem Zerbrechen der Glasscheibe der Druckknopf eingedrückt. Dabei drückt eine am Druckknopf angebrachte Schräge einen angeschrägten Schalterknopf und löst dadurch das Alarmsignal aus. Eine derartige Schaltmechanik mit dieser Art der Kraftübertragung und Umlenkung ist in der Feinwerktechnik allgemein üblich, kann jedoch im vorliegenden Fall beim Zusammentreffen ungünstiger Umstände, z.B. ungünstige Toleranzlage, rauhe Oberfläche der Gleitflächen durch fertigungsbedingte oder nachträgliche Verstaubung oder einseitige Knopfbetätigung, zu Schwierigkeiten bei der Alarmauslösung führen.In the known push button detector (type B), the push button is pressed in after breaking the glass pane. A bevel attached to the push button pushes a beveled switch button and thereby triggers the alarm signal. Such a switching mechanism with this type Power transmission and deflection is common in precision engineering, but in the present case, when unfavorable circumstances come together, e.g. unfavorable tolerance, rough surface of the sliding surfaces due to production-related or subsequent dusting or one-sided button operation, it can lead to difficulties in triggering the alarm.

Diese Problematik ist auch beim Springknopfmelder (Typ A) gegeben. Bei dem bekannten Springknopfmelder mit einer abgeschrägten Schaltkulisse ist der Springknopf durch einen federnden Stift verlängert, der an der Glasscheibe anliegt und den Springknopf in der gedrückten Stellung hält, so daß der Schalterknopf des Schalters in dieser Bereitschaftsstellung gehalten wird. Für die Alarmgabe, d.h. Einschlagen der Scheibe, wird der Springknopf durch die Druckfeder herausgedrückt und der Schalterknopf des Schalters für das Auslösen des Alarmsignals freigegeben. Diese Ausführungsform erfordert eine kostenaufwendige Ergänzung des Knopfes und weist die gleichen Probleme wie der Meldertyp B auf.This problem also applies to the spring button detector (type A). In the known spring button detector with a beveled switching backdrop, the spring button is extended by a resilient pin which rests on the glass pane and holds the spring button in the pressed position, so that the switch button of the switch is held in this ready position. For the alarm, i.e. The spring button is pushed out by the pressure spring and the switch button of the switch is released for triggering the alarm signal. This embodiment requires an expensive addition of the button and has the same problems as the detector type B.

Aufgabe der Erfindung ist es, eingangs geschilderte Handgefahrenmelder derart weiterzubilden, daß die Schalt- bzw. Betätigungsmechanik unabhängig von mechanischen Reibungskräften und Fertigungstoleranzen eine zuverlässige Alarmgabe sicherstellt und wahlweise in den oben beschriebenen Meldervarianten (Typ A oder Typ B) verwendet werden kann.The object of the invention is to further develop the manual hazard detectors described at the outset in such a way that the switching or actuating mechanism ensures reliable alarming, regardless of mechanical friction forces and manufacturing tolerances, and can optionally be used in the detector variants described above (type A or type B).

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.

Der Handgefahrenmelder, dessen Gehäuse üblicherweise eine Meldertür, ein zerbrechliches Element und einen Meldereinsatz aufweist, welcher eine Leiterplatte bzw. ein Tragelement, mindestens einen Schalter, eine Betätigungsvorrichtung mit einer zugeordneten Druckfeder sowie eine Melderwanne besitzt, weist erfindungsgemäß zwischen der Leiterplatte bzw. dem Trägerteil und der Wanne eine neu gestaltete Befestigungsmechanik auf, die von einem Bedienhebel, der an der einen Seite fixiert aber drehbar gelagert ist, einen durch die Wanne nach vorne ragenden Bedienknopf und an der anderen Seite ein federndes Element auf, welches einen Schalterknopf eines Schalters zugeordnet ist.According to the invention, the manual hazard detector, the housing of which usually has a detector door, a fragile element and a detector insert, which has a printed circuit board or a supporting element, at least one switch, an actuating device with an associated compression spring and a detector pan, between the printed circuit board or the carrier part and the tub has a newly designed fastening mechanism, which has an operating lever that is fixed on one side but rotatably mounted, a control button protruding through the tub and on the other side a resilient element that is assigned to a switch button of a switch.

Die Erfindung hat den Vorteil, daß die reibungsabhängige Kraftumlenkung am Schalterknopf um 90o entfällt, weil sie eine direkt wirkende reibungs- und toleranzunabhängige Mechanik aufweist. Ebenso ist eine sichere Schalterbetätigung durch eine toleranzunabhängige Knopfbefestigung und -führung möglich.The invention has the advantage that the friction-dependent deflection of force at the switch button by 90 o is eliminated because it has a directly acting mechanism that is independent of friction and tolerance. Safe switch actuation is also possible thanks to a tolerance-independent button attachment and guidance.

Zweckmäßigerweise kann das federnde Element von einer Blattfeder gebildet sein, welche am Bedienhebel befestigt ist. Dabei kann die Blattfeder einen Längsschnitt aufweisen, so daß die beiden Blattfederenden je ein Schaltelement betätigen können.The resilient element can expediently be formed by a leaf spring which is attached to the operating lever. The leaf spring can have a longitudinal section, so that the two leaf spring ends can each actuate a switching element.

In einer besonderen Ausgestaltung der Erfindung kann der Bedienhebel, das Bedienelement und das federnde Element einstückig, z.B. aus federndem Kunststoff, gebildet sein. In einer weiteren vorteilhaften Ausgestaltung der Erfindung kann das federnde Element von einem mehrfach abgewinkelten Federblech gebildet sein, das mittels eines Drehlagers am Bedienhebel befestigt ist.In a special embodiment of the invention, the operating lever, the operating element and the resilient element can be formed in one piece, for example from resilient plastic. In a further advantageous embodiment of the invention, the resilient element can be formed by a multi-angled spring plate which is fastened to the operating lever by means of a pivot bearing.

In Fig. 1 ist der prinzipielle Aufbau eines bekannten Druckknopfmelders, d.h. ein Handgefahrenmelder für indirekte Betätigung (Typ B) dargestellt. Im Alarmfall wird nach dem Zerbrechen der Glasscheibe 4 (zerbrechliches Element) der Druckknopf 3 in Pfeilrichtung gedrückt. Dabei drückt die Schräge 3a am Druckknopf 3 den angeschrägten Schalterknopf 5a und löst dadurch das Alarmsignal aus.In Fig. 1 the basic structure of a known push button detector, i.e. a manual hazard detector for indirect actuation (type B) is shown. In the event of an alarm, after breaking the glass pane 4 (fragile element), the push button 3 is pressed in the direction of the arrow. The bevel 3a on the push button 3 presses the beveled switch button 5a and thereby triggers the alarm signal.

In Fig. 2 ist der prinzipielle Aufbau eines bekannten Springknopfmelders (Meldertyp A) für direkte Betätigung dargestellt. Der Springknopf 3 mit der abgeschrägten Schaltkulisse 3a ist durch einen federnden Stift 6a verlängert. Der Federstift 6a liegt an der Glasscheibe 4 an und hält den Springknopf 3 in gedrückter Stellung, so daß der Schalterknopf 5a in dieser Bereitschaftsstellung gehalten wird. Im Alarmfall, d.h. beim Einschlagen der Scheibe 4, wird der Springknopf 3 durch die Druckfeder 6 in Pfeilrichtung nach außen gedrückt und der Schalterknopf 5a des Schalters 5 zum Auslösen des Alarmsignals freigegeben. Die oben geschilderten Nachteile bei diesen bekannten Meldertypen sind hier ersichtlich.In Fig. 2, the basic structure of a known spring button detector (detector type A) for direct actuation is shown. The spring button 3 with the beveled shift gate 3a is extended by a resilient pin 6a. The spring pin 6a lies against the glass pane 4 and holds the spring button 3 in the pressed position, so that the switch button 5a is held in this standby position. In the event of an alarm, i.e. when the disk 4 is knocked in, the spring button 3 is pressed outward in the direction of the arrow by the compression spring 6 and the switch button 5a of the switch 5 is released for triggering the alarm signal. The disadvantages described above with these known detector types can be seen here.

Der erfindungsgemäße Handgefahrenmelder weist eine neu gestaltete Betätigungsmechanik 19 auf, die von dem Bedienhebel 9, dem Bedienelement 3 und dem federnden Element, hier einer Blattfeder 10, gebildet ist. Auf die Leiterplatte 8 mit einem oder mehreren Druckschaltern 5 - hier sind zwei dargestellt - ist eine Wanne 7 aufgesetzt. Zwischen der Wanne 7 und der Leiterplatte 8 befinden sich der Bedienhebel 9, das Bedienelement 3 (Knopf) und als federndes Element die Blattfeder 10. Der Bedienhebel 9 ist an der oberen Seite fixiert und drehbar gelagert (9a). Die Blattfeder 10 aus Federblech ist am Bedienhebel 9 befestigt, beispielsweise mit einer Schnappverbindung. Um die Schalterbetätigungskraft bei Einsatz von mehreren Schaltern 5 annähernd gleich groß zu gestalten, ist bei diesem Ausführungsbeispiel die Blattfeder 10 längsgeschlitzt (10b). Eine Druckfeder 6 hält den Betätigungsknopf bzw. das Bedienelement 3, den Bedienhebel 9 und die Blattfeder 10 in der Ruhelage, d.h. der indirekt betätigte Melder ist in der Ruhelage betriebsbereit. (Fig.3 und 4). Das Bedienelement 3 liegt beim Meldertyp A an der Glasscheibe, d.h. am zerbrechlichen Element 4, an (Fig.). Bei dem indirekt betätigten Melder, Typ B, gemäß Fig.5 bildet die Wanne 7 die Gegenlage für das Bedienelement 3.The manual hazard detector according to the invention has a newly designed actuating mechanism 19 which is formed by the operating lever 9, the operating element 3 and the resilient element, here a leaf spring 10. A trough 7 is placed on the printed circuit board 8 with one or more pressure switches 5 - two are shown here. The control lever 9, the control element 3 (button) and, as a resilient element, the leaf spring 10 are located between the trough 7 and the printed circuit board 8. The control lever 9 is fixed on the upper side and rotatably mounted (FIG. 9a). The leaf spring 10 made of spring plate is attached to the operating lever 9, for example with a snap connection. In order to make the switch actuating force approximately the same size when using a plurality of switches 5, the leaf spring 10 is longitudinally slotted in this exemplary embodiment (FIG. 10b). A compression spring 6 holds the actuation button or the control element 3, the control lever 9 and the leaf spring 10 in the rest position, ie the indirectly actuated detector is ready for operation in the rest position. (Fig. 3 and 4). In detector type A, control element 3 rests on the glass pane, ie on fragile element 4 (FIG.). In the indirectly operated detector, type B, according to FIG. 5, the trough 7 forms the counterpart for the control element 3.

In Fig. 6 ist ein anders ausgestalteter erfindungsgemäßer Handgefahrenmelder für indirekte Betätigung, also Typ B, dargestellt. Dort ist die Betätigungsmechanik 19 einstückig, z.B. als Kunststoff-Spritzteil, ausgestaltet, d.h. der Bedienhebel 9, das Bedienelement 3 und das federnde Element 12 sind aus einem Stück gefertigt und bilden die Betätigungsmechanik 19.6 shows a differently designed manual hazard detector according to the invention for indirect actuation, ie type B. There the actuating mechanism 19 is in one piece, e.g. as a molded plastic part, i.e. the operating lever 9, the operating element 3 and the resilient element 12 are made from one piece and form the actuating mechanism 19.

In den Fig.7a, 7b und 7c ist eine weitere Ausführungsform der Erfindung dargestellt. Dabei ist anstelle der Blattfeder 10 gemäß Fig.4 und 5 ein Federblech 11 vorgesehen, das am Bedienhebel 9 mittels eines Drehlagers 9c drehbar angebracht ist. In der hier dargestellten Form kann das Federblech 11 nur nach einer Seite hin abknicken. Fig. 7a zeigt den prinzipiellen Aufbau, die Fig.7b und 7c die Funktion, wobei Fig. 7b den direkt betätigten Meldertyp A und Fig.7c den indirekt betätigten Meldertyp B zeigt.A further embodiment of the invention is shown in FIGS. 7a, 7b and 7c. 4 and 5, a spring plate 11 is provided instead of the leaf spring 10, which is rotatably attached to the operating lever 9 by means of a rotary bearing 9c. In the form shown here, the spring plate 11 can only bend to one side. Fig. 7a shows the basic structure, the Fig.7b and 7c the function, Fig. 7b shows the directly operated detector type A and Fig.7c shows the indirectly operated detector type B.

In den Fig. 8 und 9 sind zwei verschiedene Ausführungsformen für einen direkt betätigten Melder (Typ A) dargestellt. Fig. 8 zeigt einen sogenannten Springknopfmelder, bei dem nach dem Einschlagen der Glasscheibe 4 (zerbrechliches Element) die Druckfeder 6 den Springknopf 3 (Bedienelement) in Pfeilrichtung drückt. Dabei stützt sich die Blattfeder 10 an der Wanne 7 ab, wodurch das freie Ende 10a der Blattfeder 10 in die entgegengesetzte Richtung bewegt wird und den Druckschalter 5 auf der Leiterplatte 8 betätigt, was zur Alarmauslösung führt. Beim Einschlagen der Scheibe 4 kann durch hohe Schlagenergie der Bedienhebel 9 auch bis zum Anschlag eingedrückt werden. Auch in diesem Fall wird ein Alarm ausgelöst, weil der Springknopfmelder sich auch wie ein Druckknopfmelder verhält. Auch hier wird - wie bei allen Ausführungsformen des erfindungsgemäßen Melders - der Bedienhebel in der Alarmstellung fixiert, was jedoch nicht dargestellt ist.8 and 9 show two different embodiments for a directly operated detector (type A). 8 shows a so-called spring button detector, after which the glass spring 4 (fragile element), the compression spring 6 presses the spring button 3 (operating element) in the direction of the arrow. The leaf spring 10 is supported on the tub 7, whereby the free end 10a of the leaf spring 10 is moved in the opposite direction and actuates the pressure switch 5 on the printed circuit board 8, which leads to an alarm being triggered. When the pane 4 is knocked in, the operating lever 9 can also be pressed in as far as possible by high impact energy. In this case, too, an alarm is triggered because the spring button detector also behaves like a push button detector. Here too - as in all embodiments of the detector according to the invention - the operating lever is fixed in the alarm position, but this is not shown.

Fig. 9 zeigt eine sogenannte Kippglas-Ausführung. Durch Druck auf die Scheibe 4 bricht diese an der vorgegebenen Sollbruchstelle 4a (Ritzung an der Scheibeninnenseite in Knopfmitte) und kippt wie dargestellt in Druckrichtung. Dabei werden der Bedienknopf 3 und die Blattfeder 10 in Pfeilrichtung bewegt und der Alarm ausgelöst. Diese Art der direkten Betätigung ist in einigen europäischen Ländern, wie z.B. Finnland und England, üblich. Zum Schutz vor Verletzungen kann bei allen Ausführungen auf der Scheibe auf der Melderaußenseite eine durchsichtige Folie 4b eingelegt oder aufgeklebt sein.Fig. 9 shows a so-called tilting glass version. By pressing the disc 4, it breaks at the predetermined breaking point 4a (scoring on the inside of the disc in the middle of the button) and tilts in the pressure direction as shown. The control button 3 and the leaf spring 10 are moved in the direction of the arrow and the alarm is triggered. This type of direct activity is common in some European countries, e.g. Finland and England, common. To protect against injuries, a transparent film 4b can be inserted or glued on the pane on the outside of the detector in all versions.

In Fig.10 ist nochmals ein indirekt betätigter Melder, eine sogenannte Druckknopfausführung (Typ B) gezeigt. Nach dem Einschlagen der Glasscheibe 4 und Drücken des Betätigungsknopfes 3 drückt die Blattfeder 10 direkt auf den Schalterknopf 5a des Schalters 5 und löst den Alarm aus. Der Bedienhebel 4 wird anschließend durch einen hier nicht dargestellten Riegel in der Alarmstellung fixiert.In Fig. 10 there is again an indirectly operated detector, a so-called push-button version (type B). After breaking the glass pane 4 and pressing the actuating button 3, the leaf spring 10 presses directly on the switch button 5a of the switch 5 and triggers the alarm. The operating lever 4 is then fixed in the alarm position by a bolt, not shown here.
