Embodiment Construction

[0025] figure 1 Shown is a lock system according to the invention with an anti-theft turnkey S or key blank S' provided with at least two code columns Ai on its flat side and corresponding lock cylinders Za, Zb (shown in Figure 10 ), and the spring pin 3 (see Figures 6 and 7a), the locking or opening function 9 is realized by rotating the lock cylinder. The key point 11 comprises a notch 10 which cooperates with a male formation 20a, 20b on the movable counterpart 21a, 21b such that when the key is fully inserted the notch 10 just rests against the male formation 21a, 21b of the counterpart, while A key blank or key without notch 10 is blocked by a male formation 20 on the counterpart, that is to say it is prevented from being inserted completely, wherein the connecting element can be moved in the x-direction into the locking or switching position by means of the counterpart 21 .

[0026] as in Figure 2a As will be further explained in -d, the notch 10 extends from the key...

Abstract

The locking system has security turning keys (S) and associated cylinders (Z). At the key tips, the keys and also the blanks (S') thereof have a concave recess (10) which interacts with a convex formation (20) on a displaceable counterpart (21) in the cylinders such that, when the key is entirely inserted, the concave recess (10) rests flat on the convex formation (20) on the counterpart, and a key without said concave recess is locked out (a) by the convex formation (20) of the counterpart, thus preventing complete insertion, and such that a locking or switching function is made possible by the counterpart. Starting from the key tip, the concave recess (10) first of all has a first inclination (N1) and subsequently a second inclination (N2) to the key axis, with the second inclination being greater than the first inclination. These concave recesses (10) which are difficult to copy are already provided on the blanks. This provides protection for the blanks, and the security and permutation capacity of the locking system are increased.

Description

technical field [0001] The invention relates to a lock system with an anti-theft turnlock key and a corresponding lock cylinder according to the preamble of claim 1, as well as a corresponding key blank and an anti-theft turnlock key according to the preamble of claim 11, the present invention The invention also relates to a method for producing the key, the key blank and the lock cylinder according to the preamble of claim 10 . Background technique [0002] In locking technology there are some fundamental and continuing problems, on the one hand to make the unauthorized copying of keys more difficult and to adopt better and better methods of preventing such copying, and on the other hand to increase the number of keys possible Align the quantity and thereby increase the security of the lock system. [0003] US Pat. No. 5,438,837 describes a key of this type having an anti-insertion structure as an additional security element. Here, an additional control surface is provide...
