Description

Sicherheitsvorrichtungen für Türschlösser, bei denen das Schließblech durch eine drehbare Falle gebildet wird, sind bekannt.,Security devices for door locks in which the strike plate is rotatable Trap is formed are known.,

Bei diesen Einrichtungen kann man das Schloß sowohl von der Türinnen- als auch von der Außenseite sichern und entsichern.With these facilities you can open the lock from both inside and outside the door Secure and unlock from the outside.

Die neue Erfindung besteht darin, daß dieThe new invention is that the

drehbare Falle den Türschloßriegel in der Verschlußlage gegen Zurückschieben sichert.rotatable latch secures the door lock bolt in the locked position against sliding back.

ίο Eine weitere Erfindung besteht darin, daß die Falle in der Türverschlußlage schräg, also winklig zu dem senkrecht stehenden Riegel eingestellt ist.ίο Another invention is that the trap in the door locking position obliquely, so at an angle to the vertical bolt is set.

Die Erfindung läßt sich in verschiedener Weise ausführen. In der Zeichnung ist der Erfindungsgegenstand in einer Ausführungsform veranschaulicht, und zwar zeigt;The invention can be carried out in various ways. In the drawing is the Subject matter of the invention in one embodiment illustrates, namely shows;

Fig. ι eine Draufsicht auf Schloß und Schließfalle,Fig. Ι a plan view of the lock and latch,

Fig. 2 eine Seitenansicht der Schließfalle. An der Tür α ist in bekannter Weise außer dem gewöhnlichen Schloß b das Sicherheitsschloß c angeordnet, welches mit einem möglichst kleinen Schließbart ausgeführt sein kann. Das Schließblech für dieses Sicherheitsschloß c wird durch eine drehbare, um den Zapfen d gelagerte Schließfalle e gebildet, welche mit einem Längsschlitz f versehen ist, in den der Riegel g des Sicherheitsschlosses c einfaßt. Das Sicherheitsschloß ist zweckmäßigerweise nur von der Innenseite der Tür schließbar oder, falls es von beiden Seiten schließbar ist, von außen verdeckt, so daß man den Eindruck hat, daß die Tür nur mit einem Schloß versehen "ist. Nach Öffnen des gewöhnlichen Türschlosses δ wird nun der Einbrecher die Tür aufdrücken und erst dann gewahr werden, daß die Tür weiter durch eine von innen vorgelegte Türsicherung, ähnlich einer Sicherheitskette, gesichert ist. Sobald die Tür aber aufgedrückt ist, ist das. Sicherheitsschloß c gegen unbefugtes Öffnen dadurch gesichert, daß sich die Schließfalle schräg nach außen zum Schloßriegel g einstellt. Um dies zu ermöglichen, besitzt der Riegel Einschnittet. Bei Offenstellung der Tür kann also selbst · mit dem richtigen Schlüssel das Sicherheitsschloß c nicht geschlossen werden. Zweckmäßigerweise steht die Schließfalle e unter der Wirkung einer Feder i, welche die Tür immer wieder schließt.Fig. 2 is a side view of the latch. In addition to the usual lock b, the safety lock c, which can be designed with the smallest possible lock bit, is arranged on the door α in a known manner. The strike plate for this safety lock c is formed by a rotatable latch e mounted around the pin d , which is provided with a longitudinal slot f into which the bolt g of the safety lock c engages. The safety lock can expediently only be closed from the inside of the door or, if it can be closed from both sides, covered from the outside, so that one has the impression that the door is only provided with a lock Now the burglar pushes the door open and only then becomes aware that the door is further secured by a door lock, similar to a security chain, placed on the inside adjusts the latch obliquely outwards to the lock bolt g . In order to make this possible, the bolt has incisions. When the door is open, the safety lock c cannot be closed even with the correct key. The latch e is expediently under the action of a spring i that keeps closing the door.

In Fig. 2 ist gezeigt, daß die Anordnung der Schließfalle so getroffen ist, daß der Riegel auch in der Verschlußlage der Tür durch die Schließfalle gegen unbefugtes Öffnen des Sicherheitsschlosses selbst durch den richtigen Schlüssel gesichert ist. Zu diesem Zweck ist die Schließfalle schräg, also winklig zu dem senkrecht stehenden Riegel g in der Verschlußstellung eingestellt. Das Sicherheitsschloß c kann bei dieser Ausführung erst dann mit dem richtigen Schlüssel geöffnet werden, wenn man die Tür so weit öffnet, daß, durch den Riegel g beeinflußt, die Schließfalle β sich in diemEig.ästrichpunktiertgezeichnetesenkrechte Lage einstellt.In Fig. 2 it is shown that the arrangement of the lock is made so that the bolt is secured against unauthorized opening of the safety lock even in the locked position of the door by the lock itself with the correct key. For this purpose, the latch is set at an angle, that is, at an angle to the perpendicular bolt g in the closed position. In this version, the safety lock c can only be opened with the correct key if the door is opened so far that, influenced by the bolt g , the latch β is in the vertical position, which is drawn in the vertical position shown by the dashed line.
