Definitions

  • the invention relates to a rotary lock cylinder for a security lock, with a housing and one stored in it Rotor, with several in radial bores of the housing and of the rotor slidably held tumblers, each one Have housing pin and a rotor pin, and for The rotor is enabled for rotation with one to be inserted into a key channel Classify keys against the force of a spring are.
  • the invention has for its object a rotary lock cylinder to create this type, which is the mentioned unlocking method effectively prevented.
  • the rotary lock cylinder should still be inexpensive to manufacture and reliable.
  • the task is with a generic rotary lock cylinder solved in that at least one rotor pin on its on the housing pin adjacent end has a circumferential inner shoulder, which are inclined by at least 45 ° to the longitudinal axis of the rotor pin is and that the housing bore for this tumbler corresponding shoulder as well as inside has a cylindrical guide surface, the cylindrical Guide surface is designed so that the housing pin in this can be moved radially with only a little lateral play is led.
  • the aforementioned Unlocking method with at least one guard locking the rotor pin while beating the rotor back and forth through the The two shoulders work together against the force the spring is raised radially outwards with each stroke.
  • the outer end of the core pin therefore always remains in the housing and locks the rotor and prevents the unlocking of the Castle. It is now essential that this tumbler is designed in this way is that when authorized to unlock it, it works like a normal one Guard locking works safely. In particular, is a correct one Deduction guaranteed.
  • the key can therefore be used without clamps are removed from the key channel.
  • Is also ensures that all tumblers after removing the Key in the basic position and only the rotor can be tilted slightly by, for example, 0.1 mm.
  • To the mentioned cylindrical guide surface in the housing is essential. This has the effect that when one enters the rotor Housing pin the rotor is aligned with the housing. Due to the slight play of the housing pin in the cylindrical The guide surface will tilt the rotor by more than, for example 0.1 mm prevented. This ensures that all tumblers can be moved radially without jamming.
  • the rotary lock cylinder shown in Figure 1 is conventional Way from a housing 1 and a rotor mounted in this 2.
  • a key channel 8 is incorporated into the rotor 2, into which to arrange pin tumblers 5 a not shown here Flat key is to be used.
  • the rotor pin 7 is in a stepped bore 4 stored, which has a shoulder 21 on which in the position of the tumbler 5 shown in FIG Projection 20 rests.
  • the housing pin 6 and the compression spring 18 are mounted in a bore 17 of a slide 16, the is inserted into a channel 15 of the housing 1.
  • several of the stepped bores 17 are incorporated, in which one housing pin 6 is radially displaceable.
  • the feathers 18 are each supported on the housing 1 and lie on a housing pin 6 on.
  • the rotor pin 7 points against its bearing on the housing pin 6 End 10 a circumferential recess 19, the two opposite and sloping shoulders 11 and 26 forms.
  • the one in FIG. 3 with a designated angle of inclination of the shoulder 11 is at least 45 °.
  • the shoulder 11 is bordered by a comparatively narrow one cylindrical surface 23 whose diameter is the same as a likewise narrow cylindrical surface 20 which is on the shoulder 26 adjoins. Between a cambered end face 25 of the Rotor pin 7 and the cylindrical surface 23 is located also an inclined shoulder surface 24.
  • the diameter of the rotor pin 7 at the cylindrical surfaces 20 and 23 is, for example, 3 mm.
  • the stepped bores 17 of the slide 16 have an inner one cylindrical region 16, an inclined region 14 and a further cylindrical region 27.
  • the inclination of the surface 14 is preferably corresponding to that of the surface 11 and is therefore also at least 45 °.
  • the diameter of the hole 17 in the area of the cylindrical surface 13 is approximately 3.1 mm.
  • FIG. 4 shows the core pin 7 in a position in which in comparison to FIG Key channel is shifted out.
  • the core pin 7 protrudes with his inner end 10 but still in the bore 17 of the slide 16 and thereby locks the rotor 2.
  • FIG. 4 shows a tilt of the rotor 2 with respect to the slide 17 in the counterclockwise direction. This shift is comparatively small and is about 0.2 mm.
  • the rotor 2 in the opposite direction beaten, the inner shoulder 11 meets the inclined Area 14.
  • the rotor pin 7 is now correspondingly radial against the force of the spring 18 outwards in a closed position postponed. This position is shown in Figure 5.
