Lock with lock cylinder,

The object of the innovation is a lock with a lock cylinder, equipped with a device to secure the lock bolt, consisting of a constructive measure on the lock tumbler and a locking lever mounted on the lock bolt,

One technique of breaking in through the door is in the area the lock tumbler to drill through the door plate, door leaf and lock case and through this hole with suitable tools - For example, drawing pins - the eye-loosing posture ao. 'to raise that it comes out of engagement with the lock bolt and then pull it back into the lock case.

The subject of the innovation prevents the effectiveness of such burglary techniques. Usually the lock cylinder "Correctly" attached to the lock, i.e. the nose of the lock cylinder protrudes - when the key is removed - in the direction of the rear edge of the lock out of the round body of the lock cylinder. In some cases, however, the lock cylinders are attached "incorrectly" to the lock! i.e. » the nose then points in the direction of the cuff. In both cases, the subject of the application is effective.

The subject of the innovation is shown on the accompanying drawing «

In the lower area of a lock case, consisting of the lock base 1, the - lock cover - not shown - and the cuff, a lock bolt 3 is mounted horizontally displaceably. The lock bolt 3 is guided on the one hand through an opening k in the

Cuff 2 and on the other hand through a slot 6 penetrating through Round bolt 5 «The lock bolt 3 is a lock

Slidably assigned device 7, which is mounted vertically in the lock case and of which the elongated holes 8 and 9 penetrating round bolts 5 and 10 is guided. The lock tumbler 7, which is under the pressure of a spring 11, engages with its locking webs 12, 12 · and 12 ·· in recesses 13, 13 'and 13' ″ in the upper edge of the lock bolt 3 and locks it in its respective position. To enable the lock bolt 3 to be displaced, the lock tumbler 7 must be raised by the nose 14 of the locking cylinder 15 in such a way that the engagement of the locking webs 12, 12 'and 12' in the lock bolt 3 is canceled.

An irregular lifting of the lock tumbler 7 by means of the above-described intrusion technique is prevented by an angled extension 16 of the lock tumbler 7 when the lock cylinder 15 is "correctly" installed by the edge 17 of the extension 16 against which - when the key is removed, the fixed nose i4 of the lock cylinder 15 hits. If the locking cylinder 15 is "incorrectly" installed - the nose lh ' points in the direction of the cuff 2 - the locking lever 18 comes into operation. not shown - change or a limiting mandrel 21 on. When the lock bolt 3 is excluded, the longer lever arm 22 falls under its own weight or under the influence of a spring so that it lies directly next to the round body 15 'of the lock cylinder 15. If the lock tumbler 7 should now be raised irregularly, the lock bolt 3

still not be drawn into the lock case, because the
The locking lever 18 supported on the lock bolt 3 and supported against the round body 15 'prevents this. At a
Actuation of the lock cylinder 15 by a key is
the locking lever 18 is raised by the nose 1 ^ * into an approximately horizontal position (shown in dashed lines) and can thus not prevent the regular transport of the lock bolt 3. The limiting mandrel 21 or the change prevents the locking lever 18 from "falling through".
