Description

Alarmgeber mit einer zwischen Triebmittel und Tongeber liegenden Einschaltvorrichtung für das Triebmittel Es kommt häufig vor, daß Wächter oder einsam gehende Personen angefallen werden und daß ihre Schreie im Augenblick nicht gehört werden.Alarm device with a switch-on device located between the drive means and the sounder for the instinctual means It often happens that guards or people walking alone be attacked and that their screams are not being heard for the moment.

Vorliegende Erfindung soll dazu dienen, daß eine Person, die sich angegriffen sieht, die Verschlußvorrichtung der Alarmgranate anreißt und nun die Alarmgranate von sich aus Alarmsignale gibt, ohne daß der Angreifer die Möglichkeit hat, das Signalgeber zu unterbinden, da die Verschlußvorrichtung geöffnet ist und die stahlgekapselte Alarmgranate nicht von ihm zerstört werden kann.The present invention is intended to provide a person who sees attacked, tears the locking device of the alarm grenade and now the Alarm grenade gives alarm signals on its own, without the attacker being able to has to prevent the signal generator because the locking device is open and the steel-encapsulated alarm grenade cannot be destroyed by him.

In einer Stahlkapsel A ist eine Gaskammer B angeordnet. In dieser Gaskammer befindet sich hochkomprimiertes Gas, oder es wird in ihr nach Auslösen der Verschlußvorrichtung auf chemischem Wege hochkomprimiertes Gas erzeugt. Über dieser Gaskammer ist eine Kanüle C angeordnet, die durch eine VerschlußvorrichtungD verschlossen gehalten wird. Diese Kanüle führt zu einer Pfeife oder Sirene oder einem anderen tongebenden Instrument E. W izd durch Auslösen einer Zug- oder Hebelvorrichtung F die Kanüle geöffnet, so tritt ein Druckstrom in die Pfeife oder Sirene, und sie wird in Tätigkeit gesetzt. A gas chamber B is arranged in a steel capsule A. In this gas chamber there is highly compressed gas, or highly compressed gas is chemically generated in it after the closure device has been triggered. A cannula C, which is kept closed by a closure device D, is arranged above this gas chamber. This cannula leads to a whistle or siren or another sounding instrument E. If the cannula is opened by triggering a pulling or lever device F, a pressure current enters the whistle or siren and it is activated.

An Stelle der Gaskammer B kann auch ein Uhrwerk treten, dessen Spannung durch den Hebel F ausgelöst wird, ohne daß die Spannung wieder gehemmt werden kann. Durch das Uhrwerk wird eine Sirene oder eine Klingel betätigt.In place of the gas chamber B, a clockwork can also be used, its tension is triggered by the lever F without the tension can be inhibited again. A siren or a bell is activated by the clockwork.

Ferner kann auch statt der Gaskammer B eine Batterie angeordnet werden; durch Betätigung des Hebels Fwird ein Kontakt geschlossen, der nicht mehr gelöst werden kann. Durch den Strom der Batterie wird eine Membran betätigt.Furthermore, a battery can also be arranged instead of the gas chamber B; actuating the lever F closes a contact that is no longer released can be. A membrane is actuated by the current from the battery.
