Description

Elektrische Alarmvorrichtung zum Schutz gegen Fahrraddiebstahl. Die Erfindung betrifft eine Alarmvorrichtung zum Schutz gegen das Entwenden von Fahrrädern und Motorrädern, bei welcher durch Anheben oder Fortbewegen des Fahrrades eine Alarmvorrichtung in Tätigkeit gesetzt wird.Electric alarm device for protection against bicycle theft. the The invention relates to an alarm device for protecting against the theft of bicycles and motorcycles in which an alarm device is triggered by lifting or moving the bicycle is put into action.

Auf der Zeichnung zeigt Abb. r die Vorrichtung am Fahrrad angebracht, während in Abb. 2 bis 5 Einzelteile der Vorrichtung dargestellt sind.On the drawing, Fig.r shows the device attached to the bicycle, while in Fig. 2 to 5 items of the device are shown.

Die zur Hervorbringung des Signals erforderliche Batterie A, Schnarre oder Hupe T und Schalter K sind in einem mit Sicherheitsschloß verschließbaren Eisenblechkasten H untergebracht (Abb. 2 und 3). Die Leitung B geht von hier in die angebohrte hintere Rahmenstange L, von dort in die Stützstange F, welche an der Rahmenstange in G drehbar angeordnet ist. Die Stützstange F enthält den Leitungsanschluß mit den Kontaktfedern C, den isolierenden Sperrstift D und die Druckfeder E (Abb. 4 und 5). The battery A, buzzer or horn T and switch K required to produce the signal are housed in a sheet iron box H that can be locked with a safety lock (Figs. 2 and 3). The line B goes from here into the drilled rear frame rod L, from there into the support rod F, which is rotatably arranged on the frame rod in G. The support rod F contains the line connection with the contact springs C, the insulating locking pin D and the compression spring E (Fig. 4 and 5).

Soll das Rad gesichert werden, schließt man den Kasten auf, schaltet die Batterie A ein und bringt die Stützstange F in Stellung, so daß das Rad durch das eigene Gewicht den Sperrstift D hochdrückt und die Kontaktfedern C auseinandergespreizt werden, wodurch der Stromkreis unterbrochen wird. Bei unbefugtem Anheben oder geringem Fortbewegen, auch beim Umfallen des Rades, wird der unter Federdruck stehende Stab D frei, nach unten gedrückt und von den Kontaktfedern C -abgezogen, worauf ein Kontaktschluß eintritt und der Alarmapparat in Tätigkeit tritt. Ein Zerstören der Leitung ist ausgeschlossen, weil üieselbe in der Rahmenstange und Kontaktstange F verborgen liegt.If the bike is to be secured, you unlock the box and switch the battery A and brings the support rod F in position so that the wheel through Your own weight pushes up the locking pin D and spreads the contact springs C apart breaking the circuit. In the event of unauthorized lifting or slight The rod, which is under spring pressure, moves forward, even if the wheel falls over D free, pressed down and pulled off the contact springs C, whereupon a contact closure enters and the alarm device comes into action. Destroying the line is excluded because the same is hidden in the frame rod and contact rod F. lies.
