  • the insert 51 is particularly suitable for use as a closing cylinder side stop element for a key, as in FIG. 3 is described and / or for retrofitting conventional lock cylinders.
  • the insert 51 can be in a direction transverse to the insertion direction of the key (see, the direction of the horizontal arrow in Fig.
  • the insert 51 may have a recess 57, so that, for example, the elevation 47 of the in Fig. 3 shown key 1 during insertion of this key in the keyway of the lock cylinder core 17 on the insert 51 can be moved past.
  • Fig. 5 shown key 1, similar to the key of Fig. 1 , on the broad side of its key shank 3 a groove 7 extending from the key tip 5, in which a counter element in the form of a truncated conical elevation 9 (cf. Fig. 5A ) is trained.
  • the key bit 11 known from conventional keys, which has a plurality of notches 13.
  • the in Fig. 5A Lock cylinder 15 shown has a lock cylinder housing 16 and a lock cylinder 17 on.
  • a guide channel 25 is formed, in which in the illustrated variant in the form of two balls 59, 61 formed additional locking element due to the action of the survey. 9 pushed outwards, so can be moved transversely to the insertion direction of the key 1.
  • the guide channel 25 is not formed directly from the cylinder core 17. Rather, in a corresponding recess of the cylinder core 17, a sleeve-like guide member 63 is arranged, through which the guide channel 25 for guiding the two balls 59, 61 is formed.
  • the guide element 63 has a first portion 65 with a larger outer diameter, in which the larger ball 61 is arranged.
  • the cylinder core circumferential surface 29 facing the end of the first portion 65 has such a large opening that the lying in the plane AA housing pin 33 could penetrate into the opening when it is moved upon rotation of the cylinder core 17 on the housing pin 33.
  • Fig. 1B The statements made at the in Fig. 5A As a result, the ball 61 is displaced into an alignment position to the cylinder core peripheral surface 29, so that the ball 61 prevents the penetration of the housing pin 33 into the opening of the first portion 65 and thus no blocking of the Rotary movement of the cylinder core 17 takes place.
  • the cylinder core 17 can be rotated relative to the housing 16, without causing blocking of the rotational movement by the housing pin penetrating into the opening of the first section 65.
  • the guide member 63 also has a second portion 67, in which the smaller ball 61 is arranged and, as shown in FIG Fig. 5A can be seen protruding into the keyway 21.
  • the second section 67 forms a stop for the stop element 23, which is formed by the end region of the groove 7 facing away from the key tip 5.
  • the guide element 63 thus has a double function, since it is on the one hand for guiding the formesperrelements, which is formed in the illustrated variant of the two balls 59, 61, and on the other hand as a closing cylinder side stop element for the key-side stop element 23 is formed.
  • the closing cylinder-side abutment element lying in a separate plane see, for example, FIG. Fig. 1A with the arranged in the plane AA lock cylinder side stop element 19 and Fig. 1B saved with the arranged in the plane BB additional locking element).
  • the additional steps for attaching an additional closing cylinder side stop element see. Fig. 1A ), whereby the production of the lock cylinder 15 is simplified and the cost can be reduced.
  • Fig. 5B variant shown differs from the variant according to Fig. 5A by the configuration of relievesperrelements 27. This is in the variant according to Fig. 5B in the form of a bolt, which has a head arranged in the first section 65 of the guide element 63.
  • the guide element 63 comprises a first section 65 with a larger cross section and a second section 67 with a smaller cross section.
  • the guide element 63 is arranged in a correspondingly stepped recess in the cylinder core 17, cf. Fig. 5B .
  • the recess may for example be formed by holes whose diameter corresponds to the outer diameters of the first and second sections 65, 67 and in which the guide element 63, in particular in the manner of a fit, is inserted.
  • the second section 67 protrudes with a defined depth into the keyway 21, so that it can be ensured that the second section 67 has a stop forms for the key-side stop member 23 of the "matching" key 1 and the insertion of the key is not blocked (in too deep protruding guide member) or no stop forms (too shallow depth). Therefore, the design of the guide member 63 with a first portion 65 of larger diameter and a second portion 67 with a smaller diameter and its arrangement in a correspondingly shaped recess in the cylinder core 17 in a simple manner, the production of the lock cylinder 15 is simplified and ensured that the Guide member 63 protrudes with a defined depth in the keyway 21.
  • the additional locking element 27 is moved completely in the keyway 21 inserted "matching" key 1 through the survey 9 in the guide channel 25 to the outside, that the additional locking element 27 comes into an alignment position to the cylinder core peripheral surface 29.
  • the additional locking element 27 prevents the housing pin 33 from penetrating into the guide channel 25 during a rotational movement of the cylinder core 17 and blocking the further rotational movement.
  • Figs. 6, 6A and 6B described locking system differs from that with respect to the Fig. 5 . 5B to 5D essentially described by the fact that in the groove 7 no Survey, but a depression 10 is formed. Furthermore, in the lock cylinder housing 16 a cylinder core 17 facing sink 39 is formed, which is not twisted cylinder core 17 (FIG. Fig. 6A ) extends in extension of the guide channel 25.
  • the additional locking element 27 is designed such that it is first displaced outwardly on insertion of the key 1 from the groove 7 and engages in a blocking manner in the depression 39.
  • the end of vinsperrelements 27, which faces the keyway 21, complementary to the recess 10 is formed so that at maximum inserted key 1, the end of unbesperrelements 27 penetrates into the recess 10, whereby the additional locking element 27 is displaced such that it is not more engages in the depression 39 and thus causes no additional locking of the cylinder core 17 relative to the housing 16.
  • the additional locking element 27 counteracts the housing pin 33 and prevents jamming between the guide channel 25 and the housing pin 33 when the guide channel 25 during a rotational movement of the cylinder core 17 is moved over the housing pin 33 away.
  • the opening of the guide element 63 facing the housing pin 33 is preferably not formed so large that the housing pin can penetrate into the guide channel 25.
  • Figs. 5A and 5B fulfills the guide member 63 also in the variant according to Fig. 6A a dual function, since this is provided both to guide the relievesperrelements 27 and as a closing cylinder side stop element for the key-side stop member 23 of the key 7 of the key 1.
  • the first section 65 is tubular and has, as in particular Fig. 8 can be seen, at its end an enlarged opening into which a housing pin 33 can penetrate.
  • the second portion 67 is also tubular and has two extensions 69 which protrude into the keyway 21 and thus serve as a stop for the key 1.
  • the two extensions 69 are configured and arranged so that a survey 9 in the groove of the key 1 (see. Fig. 5 ) can be moved between the two extensions 69 and that the key-side stop member 23 can reach the extensions 69 to the plant.
  • the Fig. 9 and 10 show in perspective and cut the cylinder core 17 of the lock cylinder 15 of Fig. 5A , where in Fig. 9 no key and in Fig. 10 the "matching" key 1 is inserted in the keyway 21.
  • the "matching" key 1 has a groove 7 on its broad side 3 with the corresponding elevation 9 and depression 10 on. It is understood, however, that the described variants of lock cylinders can also be redesigned so that these with a key, as in Fig. 3 is shown and on the longitudinal side of the key shank 3 has a recess 45 with an elevation 47 disposed therein, can cooperate.
