In FIG. 1 shows the lock j in longitudinal axial section; FIG. 2- I, the lock section along the line AB in FIG. one; FIG. 3-section of the lock on the CD line on; FIG. one; FIG. 4-section of the lock along the line EF in FIG. 1 and FIG. 5 is the same along the line GH in FIG. one.

In the case / (fig. 1-4), which is fixed i in the door by means of screws 2, passed through the cover 3 (fig. 1, 2), cylinder i is placed with tooth 5 (fig. 1, 3, 4 j and 5), designed for rotating the cylinder to pull the valve 6 out of the hole in the plate 3, in order to unlock the lock.

on axis 7, a cranked lever 8 with shoulders 7 (and 7 /, of which JO shoulder is inserted into a hole in the key stem when the latter is pressed through hole J2 in cylinder 4 on shoulder 77.

Individualization of the lock is achieved by changing the angle between the direction of the slotted hole J2 and the plane of rotation of the lever 8 and by changing the length of the shoulder JO and the protrusion on it, which serves to rest the corresponding stop made in the key hole.

The subject matter of the invention.

A door lock with a locking cylinder rotating when pressing a key, characterized in that the cylinder 4 of the lock is provided with a spring-bend lever rotatable on the axis 7, the shoulder of which W is inserted into the key through the hole 2 to the second shoulder 7 / of the said a lever in order to engage the key with the locking cylinder.
