Description
Die Erfindung betrifft eine elektrische Anzeigevorrichtung für Briefkästen, bei denen durch Posteinwurf ein Kontakt geschlossen wird, der ein optisches oder akustisches Signal auslöst. .The invention relates to an electrical display device for mailboxes, in which a contact is closed by posting a post that has an optical or acoustic signal triggers. .
In größeren Wohnhäusern und Büros, bei denen die Briefkästen meistens zentral im Erdgeschoß angeordnet sind, wird das Eintreffen von Postsachen mit dieser neuen Vorrichtung automatisch an eine beliebige Stelle gemeldet. Die fast immer vorhandene Hausklingelanlage (Trafo oder Batterie) kann ohne große Leitungsänderung benutzt werden. Die Erfindung besteht darin, daß durch Einwurf von Poststücken mittels einer Waageeinrichtung (Fig. II) ein Kontakt e (Fig. II) geschlossen wird, welcher ein optisches oder akustisches Signal an einer beliebigen Stelle betätigt.In larger houses and offices, where the mailboxes are mostly are arranged centrally on the ground floor, the arrival of mail with this new device is automatically reported at any point. Almost always Existing doorbell system (transformer or battery) can be used without major changes to the line to be used. The invention consists in that by throwing mail items by means of a weighing device (Fig. II) a contact e (Fig. II) is closed, which an optical or acoustic signal is actuated at any point.
Fig. I stellt die Gesamtansicht, . Fig. II den Querschnitt durch die Waageeinrichtung mit den Kontakten und Fig. III den Grundriß dar.Fig. I represents the overall view,. Fig. II shows the cross section through the Scale device with the contacts and Fig. III shows the floor plan.
Die Kontaktanschlüsse g und f (Fig. II und III) sind einmal in der üblichen Weise direkt mit der Grundplatte i verbunden und einmal durch ein Isolierstück von der Grundplatte i getrennt.The contact connections g and f (Fig. II and III) are once in the usually connected directly to the base plate i and once through an insulating piece separated from the base plate i.
Die Neuheit besteht im wesentlichen darin, daß der Briefkasten in seinem unteren Teil (Fig. I) eine Waageeinrichtung besitzt, die beim Einwurf einen elektrischen Kontakt betätigt. Durch den langen Weg des Hebels b (Fig. 1I) und den noch längeren des damit verbundenen Kontaktstreifens e genügt das Gewicht einer Postkarte und weniger, um die Kontakte zu schließen. Das Kontergewicht d (Fig. II) sorgt in der üblichen und bekannten Weise für die Herstellung des Gleichgewichtes mit der Platte a (Fig. II) und des Gewichtes des Trägers la und der Hebel b. Um ein zu weites Herunterdrücken der Waage bei schweren Poststücken zu verhindern, wird die obere Kante c des Trägers der Waageeinrichtung und die untere Kante des Hebels lt als Begrenzung benutzt.The novelty consists essentially in the fact that the letter box in its lower part (Fig. I) has a weighing device which actuates an electrical contact when it is thrown in. Due to the long path of the lever b (FIG. 1I) and the even longer distance of the contact strip e connected to it, the weight of a postcard and less is sufficient to close the contacts. The counterweight d (Fig. II) ensures in the usual and known manner for the establishment of equilibrium with the plate a (Fig. II) and the weight of the carrier la and the lever b. In order to prevent the scales from being pushed down too far in the case of heavy mail pieces, the upper edge c of the carrier of the weighing device and the lower edge of the lever lt are used as a limit.
Um ein Festklemmen der Poststücke zu vermeiden, arbeitet die Bodenplatte a in einem Luftspalt k, der von :der inneren, 1, und der äußeren Wendung m begrenzt wird. Die Form und Ausführung der Briefkästen kann in der bisher üblichen Weise in Holz oder Metall erfolgen, wobei nur die Waageeinrichtung mit den Kontaktanschlüssen durch Losschrauben einer Abdeckung zugänglich sein muß.In order to avoid jamming of the mail pieces, the base plate a works in an air gap k, which is delimited by: the inner, 1, and the outer turn m. The shape and design of the mailboxes can be done in the usual way in wood or metal, with only the weighing device with the contact connections having to be accessible by unscrewing a cover.
