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 alarm systems for fire or police emergency calls In addition to automatic detectors, detectors for one manual operation, namely manual risk detectors, so-called "Push button" used. Such detectors are usually produced in two versions. Of the Detector type B represents an indirect actuation, a so-called push button design. Here is a Smash the glass pane and then close the push button press, i.e. the trigger element is the button (control element). With detector type A for direct actuation, a so-called spring button design, only has to the glass pane is broken in, then the jumps Button by spring pressure, i.e. is the trigger element from the disc (fragile element) plus the button (Control element) formed. In both cases, the Button movement an electrical switch actuates which the alarm message as an electrical signal to the hazard alarm system forwards. It is extraordinary it is 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) is after the Breaking the glass pane the push button pressed in. A slope attached to the push button pushes you beveled switch button and thereby triggers the alarm signal out. Such a switching mechanism with this type the power transmission and redirection is in precision engineering common, but can in the present case when unfavorable circumstances come together, e.g. unfavorable Tolerance position, rough surface of the sliding surfaces production-related or subsequent dusting or one-sided button operation, difficulties with the Trigger 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 is also the case with the spring button detector (type A) given. In the well-known spring button detector with a beveled shifting gate is the spring button through a resilient pin extends to the glass pane and the button in the pressed position holds so that the switch button of the switch in this Standby position is maintained. For the alarm, i.e. Breaking in the disc, the spring button is through the compression spring is pushed out and the switch button of the Switch for triggering the alarm signal released. This embodiment requires an expensive one Complement the button and have the same problems like 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 manual risk detectors described above to further develop such that the switching or Actuation mechanism independent of mechanical friction forces and manufacturing tolerances a reliable alarm ensures and optionally in those described above Detector variants (type A or type B) can be used.

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

Die Erfindung hat den Vorteil, daß die reibungsabhängige Kraftumlenkung am Schalterknopf um 90° 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 Force redirection at the switch button by 90 ° is eliminated because you a direct-acting friction and tolerance independent Has mechanics. Likewise, a safe one Switch actuation through a tolerance-independent button attachment and guidance possible.

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 of a Leaf spring be formed, which is attached to the control lever is. The leaf spring can have a longitudinal section, so that the two leaf spring ends each have a switching element can operate.

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 Control lever, the control element and the resilient element in one piece, e.g. be made of resilient plastic. In a further advantageous embodiment of the Invention can the resilient element of a multiple be angled spring plate formed by means of a Pivot bearing is attached to the operating lever.

    • 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 is the basic structure of a known Push button detector, i.e. a manual hazard detector for indirect actuation (type B) shown. In the event of an alarm after breaking the glass pane 4 (fragile Element) the push button 3 in the direction of the arrow pressed. The slope 3a presses the push button 3 beveled switch button 5a and thereby triggers the alarm signal out.

    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.2 shows the basic structure of a known one Spring button detector (detector type A) for direct actuation shown. The spring button 3 with the beveled Switching gate 3a is extended by a resilient pin 6a. The spring pin 6a lies against the glass pane 4 and holds the jump button 3 in the pressed position so that the switch button 5a held in this standby position becomes. In the event of an alarm, i.e. when hitting the Disc 4, the spring button 3 by the compression spring 6 pressed outwards in the direction of the arrow and the switch button 5a of the switch 5 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 one Actuation mechanism 19 on by the operating lever 9, the control element 3 and the resilient element, here a leaf spring 10 is formed. On the circuit board 8 with one or more pressure switches 5 - here two are shown - a tub 7 is placed. Are located between the tub 7 and the circuit board 8 the control lever 9, the control element 3 (button) and as spring element the leaf spring 10. The operating lever 9 is fixed on the upper side and rotatably mounted (9a). The Leaf spring 10 made of spring plate is attached to the operating lever 9, for example with a snap connection. To the Switch operating force when using to make several switches 5 approximately the same size, is the leaf spring 10 in this embodiment slit lengthways (10b). A compression spring 6 holds the operating button or the control element 3, the control lever 9 and the leaf spring 10 in the rest position, i.e. the indirect operated detector is ready for operation in the rest position. (Fig. 3 and 4). Control element 3 is in detector type A on the glass pane, i.e. on the fragile element 4 (Fig.). With the indirectly operated detector, type B, according to 5, the tub 7 forms the counterpart for the control element 3rd

    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 is a differently designed according to the invention Manual hazard detectors for indirect actuation, i.e. type B, shown. There is the actuation mechanism 19 in one piece, e.g. designed as a molded plastic part, i.e. the control lever 9, the control element 3 and that Resilient element 12 are made in 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 is shown in FIGS. 7a, 7b and 7c presented the invention. It is instead of the leaf spring 10 a spring plate 11 is provided according to FIGS. 4 and 5, that is rotatable on the operating lever 9 by means of a rotary bearing 9c is appropriate. In the form shown here, it can Only bend the spring plate 11 to one side. Fig. 7a shows the basic structure, the Fig.7b and 7c Function, Fig. 7b 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 are two different embodiments for a directly operated detector (type A). 8 shows a so-called spring button detector, in which after breaking the glass pane 4 (fragile element) the compression spring 6 the spring button 3 (control element) in the direction of the arrow. Here the leaf spring 10 is supported on the tub 7, whereby the free end 10a of the leaf spring 10 in the opposite Direction is moved and the pressure switch 5 on the circuit board 8 actuated, which leads to the alarm triggering. When driving the pane 4, high impact energy can cause it the operating lever 9 is also pushed in as far as it will go will. An alarm is also triggered in this case, because the jumping button detector is also like a push button detector behaves. Here too - as with all embodiments of the detector according to the invention - the control lever fixed in the alarm position, but this is not shown is.

    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 Pressure on the disc 4 breaks it at the predetermined Predetermined breaking point 4a (scoring on the inside of the pane in Middle of the button) and tilts in the printing direction as shown. The control button 3 and the leaf spring 10 in The direction of the arrow moves and the alarm is triggered. This kind direct activity is in some European Countries, such as Finland and England, common. For protection injuries can occur in all versions on the A transparent film on the outside of the detector 4b inserted or glued.

    In Fig.10 ist nochmals ein indirekt betätigter Melder, eine sogenannte Druckknopfausführung (Typ B) gezeigt.
