Definitions

  • the invention relates to a lock and key system, with a cylinder core rotatably mounted in a lock cylinder housing, in the key channel of which a key provided on the side surfaces of the key shank with a profile and breast side with a mechanical coding in the form of notches can be inserted.
  • these pins are similar to the parting plane between the cylinder core and the lock cylinder housing such that free rotation of the cylinder core is possible to perform a closing operation.
  • this object is achieved with a lock-key system, with a rotatably mounted in a lock cylinder housing cylinder core, in the key channel on the side surfaces of the key shank with a profile and breast side with a mechanical coding in the form of notches provided key is inserted and, by doing so, that in the lateral profile of the key a stepped stepped counterbore is introduced at a certain angle, which is interrogated by a arranged in bores in the cylinder core and the lock cylinder housing telescopic pin combination, the telescopic pin in the cylinder core of an inner core stylus and an outer core stylus and the telescopic pin in the lock cylinder housing consists of an inner and outer housing pin and both core feeler pins can be pressed or pulled towards the center of the core.
  • a stepped lowering of the mold is introduced into the key at a certain angle.
  • This countersink is interrogated by a telescoping pin combination consisting of an inner core stylus and an outer stylus and inner and outer housing stylus.
  • Both core pins are pressed in one embodiment of the system according to the invention by means of a leg spring towards the core center.
  • On the inner core pin is a magnet, which is guided in the outer core pin.
  • the inner core pin and the housing pins are made of a magnetic material so that the housing pins can follow the core pins. Now, if the mold reduction is properly scanned by the pin combination, so forms the separation plane between the cylinder core and housing and allows the core rotation.
  • the advantage of the solution according to the invention is that the introduced into the key side stage mold reduction can only be made with a special tool.
  • This tool must be at a certain angle to the key and also requires a precise position to the key side. This means that the positioning of the tool 3 requires dimensional coordinates and is therefore very difficult to copy. This reduction is preferably introduced into a profile projection of "bottom” or "top” in the key.
  • Scanning is done via a pin - in - pin combination, with the housing pins eliminating the need for external springs.
  • the housing pins are pulled by a magnet to the core pins, so that the movement of the core pins are transmitted to the housing pins.
  • the core pins are pressed by a leg spring towards the center of the core, so that the key is actively scanned.
  • the key may consist of a magnetic material wholly or partly (in the area of the countersink).
  • the leg spring can be omitted, since then this magnetic material acts directly on the telescopic pin combination, ie this pulls towards the core center.
  • the outer core stylus also consists of a magnetic material.
  • FIG. 1 shows the key 1, which is inserted into the keyway of a rotatably mounted in the lock cylinder housing 5 cylinder core 7.
  • the lock cylinder housing 5 has a corresponding bore 6 in which the housing pins 14 and 15 can move.
  • the cylinder core 7 has a corresponding to the bore 6 in the housing aligned bore 8 in which the core feeler pins 9 and 11 move.
  • the key 1 is in the correctly inserted into the key channel position so that the styli form a common parting line to the housing 5.
  • the outer core stylus 9 is slotted 10 so that the leg spring 16 can depress both core styli.
  • the inner core stylus 11 has a bore 12 into which the leg spring 16 engages.
  • On the inner core stylus 11 is an axially polarized magnet 13, which adheres both to the magnetic material of the inner core stylus 11, as well as the magnetic housing pins 14 and 15 pulls towards the core center.
  • the plate 17 holds the leg spring 16 in position.
  • the representation in the figure is based on a correct, so suitably coded, key, so that the scan of the mold reduction with the surfaces 3 and 4 leads to a balance of the pins on the parting plane and thus a closing operation would be executed.
  • FIG. 5 a modified embodiment is shown.
  • the pressure acting in the direction of the core center on the housing pins pressure is not achieved by a magnet assembly, but by the arrangement of two compression springs, wherein on the inner housing pin 23 and the outer housing pin 24 each have a arranged in the lock cylinder housing 5 spring 22nd or 21).
  • the springs 22 and 21 are preferably arranged coaxially with each other.
