Embodiment Construction

[0025] figure 1 Shows a lock system according to the present invention, which has an anti-theft turn lock key S or key blank S'(with at least two code rows Ai on its flat side) and corresponding lock cylinders Za, Zb (shown in Picture 10 ), and the elastic pin 3 (see Figures 6 and 7a), the locking or opening function 9 is realized by rotating the lock core. The key tip 11 includes a notch 10 that cooperates with the convex structures 20a, 20b on the movable counterparts 21a, 21b, so that the notch 10 just abuts on the convex structures 21a, 21b of the counterpart when the key is fully inserted, and The key blank or key without the notch 10 is blocked by the convex structure 20 on the counterpart, that is to say, prevents it from being fully inserted, wherein the counterpart 21 can be used to move the connecting element in the x direction to the locked or switch position.

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

Abstract

The locking system has security turning keys (S) and associated cylinders (Z). At the key tips, the keys and also the blanks (S1) 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 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 present invention relates to a lock system with an anti-theft turn lock key and a corresponding lock cylinder according to the preamble of claim 1, and a corresponding key blank and an anti-theft turn lock key according to the preamble of claim 11. The invention also relates to a method for manufacturing the key, key blank and lock cylinder according to the preamble of claim 10. Background technique [0002] In the locking technology, there are some basic and continuous problems. On the one hand, it is more difficult to make unauthorized copying of keys, and better and better methods are used to prevent such copying. On the other hand, it is necessary to increase the possibility of keys. Arrange the number, and thereby improve the safety of the lock system. [0003] US Patent 5438837 introduces a key of this type, which has an anti-insertion structure as an additional security element. Here, the key is provided with an additional control surface, which ...
