Definitions

  • the invention relates to a cross-sectional profile of a Flat key or the key channel of an associated one Lock cylinder, with a longitudinal profile plane, which from the narrow sides of the cross-sectional profile is limited and V-shaped towards the narrow sides tapering, opposite profile sections.
  • a cross-sectional profile of the type in question is known from EP 0 567 832 A1, the longitudinal profile plane at an acute angle runs through the Tumbler pins along the longitudinal median plane of a profile lock cylinder such that the one on one side the section of the key shaft located in the aforementioned median longitudinal plane.
  • Using modern picking devices which with high impact and high, if necessary adjustable frequencies can also work the tumbler pins even with such cross-sectional profiles Therefore, to prevent unauthorized opening of locking cylinders using the picking method prevent paracentric profiles which developed block the picking needle on the way to the core pins should. This is largely possible when used manual picking tools or at proportionate weak electric picking devices.
  • the object of the invention is based on the object to create a generic cross-sectional profile, in which the opening of the lock cylinder also Use of high impact and frequency workers Picking equipment is largely prevented.
  • This task is first and foremost a cross-sectional profile with the features of the claim 1 solved, it being based on the fact that the Profile longitudinal center plane in the direction of escape of the cylinder pin axis or the locking notches Key shaft narrow side runs.
  • the narrow end surfaces the profile sections through a movement channel connected for the picking needle.
  • the narrow end faces by a straight line To connect the movement channel with each other.
  • the profile sections are acute-angled converging towards the narrow end surfaces Form leading wall sections. These run inclined to the plane of vibration of the picking needle and effect through the picking needle hitting it Braking or blocking effect. It turns out to be optimal doing that the mouth width between the wall sections is larger than the width of the picking needle and the The width of the narrow end faces is smaller than the width the picking needle.
  • the Profile sections that are parallel to the longitudinal plane of the profile protrude extending broad sides.
  • the cross-sectional profile can then be a paracentric basic profile train so that even when using manual picking tools opening according to the Hobbian opening method is difficult.
  • the Profile longitudinal center plane and the movement channel center plane included angle is less than or equal to 45 °. This angle is dependent on the paracentric To determine the basic profile provided that the picking needle is in the key channel under one Angle of approximately 30 ° is introduced to the maximum To achieve vibration amplitude.
  • the protrusion of the profile sections is so large chosen that it corresponds to about half the profile thickness.
  • the corresponding flat bowl is with one Cross-sectional profile according to one or more of the preceding Designed claims. This also applies a lock cylinder with a key insert profile to which according to one or more of the preceding Claims is designed.
  • Acting with respect to the locking cylinder 1 shown it is a double profile locking cylinder.
  • This has a housing G with a circular plan Section 2, from which radially projecting Flange section 3 runs out. Then the housing G with one starting from the circular section 2 Cutout 4 provided for receiving a closing member 5 with a radially protruding lock bit 6.
  • Both sides of the cutout 4 are stored in each circular Section 2 in a core bore 7 a cylinder core 8.
  • This has a key channel 9, the Profile longitudinal center plane x-x with the movement plane of successive, pin tumblers arranged in the housing flees. Every pin tumbler sits down together from a core pin 10 and one in the direction the same spring-loaded housing pin 11, the Core pins 10 facing ends of the housing pins 11 with the key removed, into the core pins 10 protruding core holes and thus the Lock the rotary movement of the cylinder core 8.
  • the longitudinal profile plane x-x of the key channel 9 is limited by the narrow sides of the cross-sectional profile.
  • Towards the narrow sides of the key channel are V-shaped, opposing profile sections 12, 13 provided.
  • a corresponding angle is also in the profile section 13, but what is not shown.
  • Regarding the profile sections 12, 13 are the first to face each other Profile sections, parallel to which there are second also V-shaped projecting profile sections 14, 15 extend. The latter are the cross-sectional plane of the profile adjacent, so have a smaller distance to this as the first profile sections 12, 13.
  • the second profile sections 14, 15 also run at an angle of about 45 ° to the longitudinal profile plane x-x.
  • the narrow end surfaces 12 ', 13' of the profile sections 12, 13 are through a movement channel B for a picking needle 16 connected together.
  • the latter is part of it an electric picking device, which with high Clout and high frequency works.
  • the frequency is also adjustable if necessary.
  • the movement channel B is approximately rectilinear.
  • the movement channel has an angle of about 30 ° to the longitudinal profile plane x-x. Under this the picking needle 16 is inserted into the key channel 9, where the maximum vibration amplitude of the Picking needle is reached.
  • the profile sections 12, 13 to converge at an acute angle the narrow end surfaces 12 ', 13' leading wall sections 12 '', 12 '' 'or 13' ', 13' ''.
  • Fig. 2 illustrates that the cross-sectional profile is a paracentric Basic profile is. That means that from the broadsides 17, 18 outgoing profile ribs at least extend to the profile longitudinal center plane x-x.
  • first profile sections 12, 13 protrude the second profile sections 14, 15, which with respect their dimensions of the first profile sections 12, 13 correspond to the broad side surfaces 17, 18 of the basic profile.
  • the protrusion of the profile sections 12, 13, 14, 15 corresponds approximately to half the profile thickness.
  • cross-sectional profile the key channel 9 of a lock cylinder 1 described.
  • Cross section of the associated flat key in which the profile sections as appropriately aligned Ribs are designed.
  • the cross-sectional profile of the Key channel 21 corresponds to the basic profile of the Key channel 9 of the embodiment described above. This means that the key channel 21 has no profile sections assigned. Because of this fact a picking needle 16 into the key channel 21 introduce such that the vibration amplitude y under at an angle of approx. 30 ° to the longitudinal mid-plane x-x runs. Because there are no profile sections on the key channel 21 are present, the picking needle 16 to the beveled tips of the core pins take full effect and classify them.
