Abstract

Doors provided with cylindrical mortise dead locks can be opened by drilling a hole on a convenient place of the door leaf near to the outline of the lock and by inserting a suitable tool into the drilling the bolt can be operated by lifting the tumbler. The cylinder lock is fitted with a cam which protrudes from the lock housing resting against the bolt extension and hereby blocking any movement. In order to release the blockage, the cylinder lock has to be operated by the proper key, whereupon the cam is retracted and the bolt can be slid out of the locked position.

Description

Betr.: Abtast-Sicherung für Zylinder-Einsteckschlösser Beschreibung Die Erfindung betrifft ein Einsteckschloß für Zylindervorgerichtet mit einer durch den Sohließbart des Zylinders abtast-geschtftzen Zuhaltung.Re: scanning protection for cylinder mortise locks Description The invention relates to a mortise lock for cylinder devices with a through The guard locking device is scanned on the base of the cylinder.

Durch Anbohren der TUr z.B. bei (3) oder (4) können alle handelsUbllchen Zylinder-Einsteckschlösser unter Umgehung des Sicherheitszylinders leicht abgetastet und gebffnet werden. Eine Reihe von Einbrtichen wurden in dieser Form bisher durchgeführt.By drilling the door, e.g. at (3) or (4), all small commercial areas can be opened Cylinder mortise locks lightly scanned while bypassing the security cylinder and be opened. A number of collisions have been carried out in this way so far.

Die neue Idee koppelt das Anheben der Zuhaltung (1) mit der Bewegung des Schließbartes (2) und macht damit ein unbefugtes Abtasten des Schlässes unmöglich.The new idea couples the lifting of the guard locking (1) with the movement of the lock bit (2) and thus makes unauthorized scanning of the lock impossible.

Im abgeschlossenen Zustand sind Riegel und Zuhaltung durch den Schlleßbart des Zylinders blookiert und damit gegen Abtasten geschützt. Nur mit Hilfe des richtigen SohlUsgels wird die blockierte Zuhaltung wieder freigegeben.The bolt and guard locking by the lock bit are in the locked state of the cylinder blocked and thus protected against scanning. Only with the help of the right one SolUsgels, the blocked guard locking is released again.

Das Anheben der Zuhaltung und damit das Öffnen des Schlosses wird von der Bewegung des Zylinder-Schließbartes abhängig gemacht und ist somit nur lit Hilfe des richtigen Schlüssels möglich. The lifting of the guard locking and thus the opening of the lock is made dependent on the movement of the cylinder lock bit and is therefore only lit. Possible with the help of the correct key.
