Definitions

  • the invention relates to a locking device which consists of a Cylinder lock and a flat key, being that cylinder lock from a cylinder housing with a rotatably mounted cylinder core is formed, the cylinder core with a key channel to insert an associated flat key and this Flat key equipped with locking notches on its key face which, in turn, is radial in the bores of the cylinder core Guided tumblers as well as on the longitudinal median plane act laterally and essentially parallel to the longitudinal median plane at least one supplementary tumbler is arranged that from a side core pin mounted in the cylinder core and an in Lower part of the cylinder housing provided spring-loaded side housing pin there, the mutually facing ends of this two longitudinally movable pins form a parting line, the corresponding the course of those formed between the cylinder housing and the cylinder core Core rotary joint is curved and the supplementary tumbler by a in a recess transverse to the longitudinal median plane in the cylinder core movable and by one in a side surface of the Flat key located rece
  • control element as a spring-loaded, rocker-shaped double lever formed, which extends in the longitudinal direction of the key channel and about a transverse, parallel to the longitudinal median plane bearing axis pivotable to the longitudinal direction of the key channel is.
  • the double lever is used to control the additional guard locking on its underside there is a recess which is frustoconical Deepening and thus as a working surface for the one corresponding Counter-shaped side core pin designed is.
  • control element is designed as a ball and in a Hole designed recess in the area between the key channel and the side core pin.
  • the end of the side core pin is conical, whereby those already regarding the convex formation of the donor ends identified disadvantages (only small lifting height of the side core pin feasible, so that again the variety with regard the usable different side core pin lengths and equivalent depths of the recesses in the side surface of the flat key is severely restricted) also on the one discussed here Effective point of the locking device become effective.
  • EP 0 557 606 A1 also documents a non-generic one Solution in which the control element is also designed as a ball is.
  • the invention relates to a locking device, which automatic anti-rotation / centering of the control chain, Side core pin and side case pin even when fast Inserting and removing the flat key secures and without additional components to ensure security against rotation gets along, a simple structure, small space requirement, low Installation effort and high functional reliability and essentially using standardized components can be realized.
  • this is the case with a locking device of the above Generic achieved in that the control element is designed as a ball and in a recess designed as a bore in the area between the key channel and the side core pin is arranged as well as the side core pin on its end facing the ball one in the direction of the transverse to the longitudinal median plane Bore increasing effective area that extends over the entire Front side of the side core pin extends.
  • the advantages of the invention are that by the interaction of the control element designed as a ball in connection with the end face of the side core pin designed as an increasing active surface an automatic centering and thus a functional position assurance the components of the side core pin and side housing pin in relation to the congruence between joint and core twist joint he follows.
  • the self-centering of the supplementary tumbler elements is permanently available or even when plugged in quickly or removing the flat key immediately, by a surface-aligning surface contact between the sphere and the active surface and the mutually facing ends of the side core and Side case pins are made.
  • FIG. 1 shows the locking device according to the invention. This consists of a cylinder lock 1 and a flat key, the cylinder lock 1 essentially from the cylinder housing 2 and the cylinder core 3 rotatably mounted therein. in the Cylinder core 3 is a key channel 4 for inserting the key shaft 5 of the associated flat key provided.
  • cylinder core 3 and in the lower part 6 of the cylinder housing 2 are in alignment mutually arranged bores arranged, several in different Cross-sectional planes and along the median longitudinal plane 7 of the cylinder core 3 arranged core pins different Radially lead length, which in turn from in the cylinder housing 2 held and spring-loaded housing pins so that these housing pins when the flat key is not inserted protrude into the bores of the cylinder core 3 and thus this lock against rotation relative to the cylinder housing 2 (in essential not visible).
  • the key shaft 5 of the associated flat key is equipped on its key face with variable locking notches 8, which in turn interact when the shaft 5 of the flat key is inserted into the key channel 4 of the cylinder core 3 with the core pins guided in bores of the cylinder core 3 along the longitudinal center plane 7.
  • this is done in such a way that the ends of the core pins on the cylinder housing side form a joint joint 22 with the ends of the housing pins on the cylinder core side, which joint then runs along the core joint 9 between the cylinder core 3 and the cylinder housing 2.
  • a supplementary tumbler is arranged on both sides and parallel to the longitudinal center plane 7 (FIG. 1) as well as in different cross-sectional planes (FIG.
  • the supplementary tumbler is actuated by a control element 16, which is designed as a ball 16 'and is movable in a region 15 between the key channel 4 and the side core pin 10, in a recess 15 of the cylinder core 3 which is designed as a bore 15' and which is arranged in the region between the key channel 4 and the side core pin 10, the side core pin 10 on its end face 17 facing the ball 16 'has an active surface 18 which rises in the direction of the bore 15'.
  • the ball 16 ' can be controlled by the recess in the side surface 19 of the shaft 5 of the flat key, which is designed as a trough 20 and is variable in depth (FIG.
  • a stop element designed as a bolt 21 is arranged in the longitudinal direction of the cylinder core 3 in the region of the bores 15' on the cylinder housing side - FIGS. 1 to 3.
  • the displacement of the ball 16 'located in the bore 15' in the direction of the cylinder housing 2 is also connected, so that the active surface 18 which rises towards the bore 15 'at the end face 17 of the side core pin 10 and bears against the ball 16'
  • Maintenance of the existing self-centering between the side core pin 10 and the side housing pin 12 also the curved ends 13 and 14 of the side core pins 10 and the side housing pins 12 touching one another over their entire surface
  • the separating joint 22 located between the side core pin 10 and the side housing pin 12 assumes a congruent position with the core twist joint 9 between the cylinder housing 2 and the cylinder core 3 - FIG. 1 -.
  • supplementary tumbler or - Tumblers in different cross-sectional levels to those in the Drawings not shown and arranged in the longitudinal center plane 7
  • pin tumblers i.e. the supplementary tumbler or tumblers (10, 12, 16 ') are laterally on the gap between two adjacent and located on the longitudinal median plane 7 Pin tumblers arranged, effectively reducing the restricted spatial possibilities on the cylinder core 3 and in the cylinder housing 2 Is taken into account.
