Description

Die Erfindung betrifft einen zum Schütze gegen Einbruch und Diebstahl dienenden elektrischen Signalschalter, der, an einen Stromkreis angeschlossen, bei leichter und kurzer Erschütterung ein einmaliges, mehrfach unterbrochenes Alarmsignal bewirkt, während er durch leichte und längere Erschütterung ein längeres, mehrfach wiederholt unterbrochenes und durch starke Erschütterung ein dauerndesThe invention relates to an electrical device used to protect against burglary and theft Signal switch, which, when connected to a circuit, causes a single, multiple interruption in the event of light and short shocks The alarm signal causes, while it is a longer, repeatedly interrupted by light and prolonged vibration and a permanent one through strong shock

ίο und ständiges Alarmsignal hervorruft.ίο and causes constant alarm signal.

Je nach der Erregungsursache der verschiedenen Alarmsignale ist aus der Art des Signals leicht festzustellen, ob die Befürchtung einer Einbruchsgefahr droht oder nicht. Denn die zufällige Erschütterungen durch Luftdruck usw. sind fast immer nur leichte von kurzer Dauer. Dagegen sind die Erschütterungen durch Einbrüche anfangs meistens leichte, aber von längerer Dauer, welche durch Ausbohren des Türschlosses oder Ausschneiden der Füllungen erfolgen, denen jedoch eine stärkere Erschütterung durch Öffnen oder Ausbrechen der Tür usw. folgt.Depending on the cause of the excitation of the different alarm signals is from the nature of the It is easy to determine whether there is a risk of break-in or not. Because the accidental vibrations caused by air pressure, etc., are almost always only slight and brief Duration. On the other hand, the vibrations caused by break-ins are initially mostly light, but of longer duration, which can be achieved by drilling out the door lock or cutting it out of the fillings are made, which, however, have a stronger shock when opening or Breaking out of the door etc. follows.

Der Schalter besteht aus dem Tasthebelrohr a, welches in einer ausgebohrten Öffnung b der Isolierplatte c zwischen zwei ausgebohrten Lagerplatten d und d¹ mit einer Gelenkkugel e nach allen Seiten frei beweglich in einem Gehäuse f gelagert ist. Die Lagerplatten d und d¹ sind mit der Stromeintrittsklemme u miteinander verbunden. Der Tasthebel α trägt am unteren Ende des Hebelarmes eine in das Gehäuse hochschiebbare Tastscheibe g mit Knopfstiften h und in der Mitte des unteren Teils eine in Gleitschlitzen i verstellbare, in der Mitte durchbohrte Kontaktscheibe k, durch deren Öffnung I zwecks Stromunterbrechung und -Schließung eine Stahldrahtschwingfeder m mit verstellbarem Schwinggewicht η geführt ist, welche im oberen Hebelarmrohr durch einen Isolierschaft p mit leitendem Kopf q vom Hebelarm α leitend getrennt befestigt ist und als leitende Stütze einer auf ihr ruhenden leitenden, konvex und konkav ausgebogenen Schaltglocke r dient.The switch consists of the probe lever tube a, which is mounted in a drilled opening b of the insulating plate c between two drilled bearing plates d and d ¹ with a joint ball e in a housing f so that it can move freely on all sides. The bearing plates d and d ¹ are connected to one another by the current inlet terminal u. The feeler lever α carries at the lower end of the lever arm a feeler disk g with button pins h that can be pushed up into the housing and in the middle of the lower part a contact disk k that is adjustable in sliding slots i and drilled in the middle, through the opening I of which a steel wire oscillating spring is inserted for the purpose of current interruption and closure m is guided with an adjustable swing weight η , which is attached in the upper lever arm tube by an insulating shaft p with a conductive head q from the lever arm α conductively separated and serves as a conductive support for a conductive, convex and concave bell crank r resting on it.

Claims

drilled insulating plate, ·> - is mounted, the conductive spring t presses. The spring t is connected to the insulating plate .s · through the current outlet terminal ti ¹ and has an adjusting screw w which is guided through the insulating cover plate χ. "At the lower end of the housing / there is a very soft felt ring y, which cuts off with the curve of the feeler disc g and is intended to prevent the transmission of the ίο vibration vibrations to the housing /.

The Arteitsgang is as follows: As soon as the tactile disc g- is moved by vibration by z. B. in the event of danger, protective threads attached to doors or windows, one end of which can be connected to the buttons h of the disk g , impact the disk g , it transmits this vibration through the joint ball c to the upper lever arm a. The steel wire oscillating spring m fastened in the lever arm is made to vibrate and repeatedly touches the contact disk k, whereby the circuit is repeatedly closed and interrupted; depending on the duration of the shock, the alarm signal is activated.

If the tactile lever tube α is attacked by a strong shock, the process is repeated as before, but with the difference that the conductive head q in the upper tactile lever α is pressed from the convex elevation down into the concave recess of the switching bell r. Simultaneously, the control cam is r of the base removed and this with its concave recess by the spring guide t to the conductive head pressed q, whereby a skew of the sensing lever is α causes and the steel wire resonant spring M by the vibrating weight n on the contact disc is printed k (Fig . 2). In this way the circuit is always closed and a permanent alarm signal is generated. The embodiment of the switch can be different according to the invention. So z. B. instead of the tactile lever tube α a cranked tactile lever, instead of the joint ball e a universal joint, instead of the switching bell r a ball etc. and instead of the steel wire swing spring m a differently designed pendulum can be attached.

Such and other embodiments of the invention are inexpensive manufacturable. The essence of the same, however, remains the reception and transmission of different types of vibrations by one that is freely swinging in all directions Sensing lever and a steel wire oscillating spring connected to it, freely oscillating on all sides and guided through a contact disc or a pendulum, the repeated interrupted contact for slight shocks due to vibrations of the Steel wire swing spring takes place in a contact disc, while the constant con- tact as a result of strong vibrations caused by the inclined position of the feeler lever also by means of Pendulum or the steel wire oscillating spring in the contact disk takes place.

Patent-A ν Proverbs:
