A. ROSENBERG in BERLIN. Sicherheitskette an Thiiren.A. ROSENBERG in BERLIN. Security chain to Thiiren.
Patentirt im Deutschen Reiche vom 27. Mai 1879 ab.Patented in the German Empire on May 27, 1879.
Die gegenwärtig bekannten Sicherheitsketten entsprechen den an sie gestellten Anforderungen nicht, weil sie gestatten, dafs sie von aufsen durchgefeilt oder der sie haltende Theil an der Thür losgeschraubt wird, ohne grofses Geräusch dabei zu verursachen.The currently known safety chains meet the requirements placed on them not because they allow them to be filed through from the outside or the part holding them on the The door is unscrewed without making any great noise.
Die hier erläuterte Construction umgeht diese Uebelstände und läfst dabei ein leichtes Oeffnen der Thür nach dem Willen des Besitzers zu, und kann sie ferner in einem Augenblick zu einem das Bewegen der Thür absolut verhindernden Verschlufs umgewandelt werden.The construction explained here bypasses these inconveniences and allows easy opening the door to the will of the owner, and it can also move the door in an instant absolutely preventive encryption.
Die Sicherheitskette besteht aus der Verbindungsgabel a, welche durch die Kette b mit dem Befestigungsblech c verbunden ist; sodann aus der Platte d, auf welche die um den Stift e drehbare Kurbel / mit Knopf i befestigt ist, die jedoch wegen des Anschlagestückes g nur eine halbe Drehung machen kann.The safety chain consists of the connecting fork a, which is connected to the mounting plate c by the chain b ; then from the plate d, on which the crank / knob i , which can rotate about the pin e , is attached, but which can only make a half turn because of the stop piece g.
Das Befestigungsblech c wird so an die Thürbekleidung (oder bei Flügelthüren an· dem feststehenden Flügel) angeschraubt, dafs die Oese h eine waagerechte Lage einnimmt.The fastening plate c is screwed to the door cladding (or, in the case of wing doors, to the fixed wing) in such a way that the eyelet h assumes a horizontal position.
Hierauf befestigt man die Platte d in der Weise an die Thür, dafs der Drehpunkt m der Kurbel / in gleicher Höhe mit der Oese h zu liegen kommt und die Kurbel selbst nach der Platte c weist, und zwar so, dafs bei mäfsig angezogener Kette der Knopf i willig durch die Oeffnung k hindurchgeht. The plate d is then fastened to the door in such a way that the fulcrum m of the crank / comes to lie at the same height as the eye h and the crank itself points to the plate c , in such a way that, when the chain is moderately tightened, the Button i willingly goes through the opening k .
Bei dieser Lage der Kette kann die Thür so weit geöffnet werden, als es die Länge der Oeffnung in der Verbindungsgabel α zuläfst.With the chain in this position, the door can be opened as far as the length of the opening in the connecting fork α allows.
Soll jedoch z. B. zur Nachtzeit die Kette vorgelegt werden, so schliefse man die Thür, drehe alsdann die Kurbel / so weit herum, dafs sie ihre halbe Drehung vollendet und das Anschlagestück g auf der anderen Seite berührt, so wird die Kette b straff angezogen und bildet einen festen Verschlufs, der das Oeffnen der Thür verhindert.However, if z. If, for example, the chain is presented at night, the door is closed, then the crank is turned so far that it completes its half turn and touches the stopper g on the other side, the chain b is tightened tightly and forms one tight lock that prevents the door from opening.
