Definitions

  • the present invention relates to a flat key for a lock cylinder, in particular of locking systems, with substantially flat and approximately parallel key flat sides, a key back and this opposite, toothed on the front side key bit for positioning split into core and housing pins tumbler pins in corresponding key channels of cylinder cores are spring-loaded against the front side of the key bit toward the key back, being provided in the flat sides of the flat key grooves as variation profile elements and as a guide profile elements, wherein at least two grooves of a side of the flat key overlap, the Einstechraumsch is different, so that through the Intersection of the two grooves results in an edge which can be scanned in the direction normal to the longitudinal center plane of the flat key, wherein further overlapped by the two Both grooves are undercut under both ends, and in opposite directions, and wherein the center of the groove bottom - seen in the direction normal to the longitudinal center plane of the key - is covered by these undercuts in at least one groove.
  • the invention further relates to a lock cylinder for such a flat
  • a lock and a key are of particular importance.
  • access areas are defined and implemented by assigning each asset key to one or more locks. This assignment or the exclusion of key and lock with respect to the lock function is achieved in locking systems based on lock cylinders with flat keys, inter alia, by the cross-sectional profile of the key and the cross section of the keyway. Only if the contour of a Key channel cross-section corresponds to a flat key cross-section or wraps this, fits the key in the lock. As soon as the contour of the flat key cross section intersects that of the key channel cross section, the key has no blocking authorization with regard to the abovementioned lock cylinder.
  • a replacement key can be procured from the authorized person by means of security notes and strict identity checks. If key blanks are commercially available, a key service with a copy milling device can easily make a spare key by making teeth on the key-breast. If a Kopierfräs coupled is also able to scan a cross-sectional profile on the flat sides of an original key and appropriate milling tools are available, a spare key can also be machined from a metal plate machined.
  • this is achieved in that at least one groove and the transition from the groove flank to the groove bottom through the undercut - seen in the direction normal to the longitudinal center plane of the key - is covered.
  • the two undercut angles are different.
  • a re-milling with a trapezoidal cutter also causes a different formation of at least one groove flank.
  • this can not be closed from the angle of a groove on the angle of the other groove, which would facilitate the measurement of the original key.
  • the two grooves are provided as guide profile elements.
  • the guide profile is included in a locking system trained each key, so thus the desired security is given in any case.
  • the groove flank of the Trognut encloses an angle ⁇ less than 90 °, preferably between 30 ° and 45 °, with the median plane of the flat key and the other side edge of the Trognut includes an angle ⁇ between 93 ° and 97 ° with the median plane of the flat key.
  • a lock cylinder for a flat key of the type described above is equipped with a cylinder housing and at least one rotatably disposed in a bore of the cylinder housing cylinder core having a profiled keyway, and divided into core and housing pins Zuroisslixen in bores in the cylinder housing and the cylinder core are spring loaded against the front side of the key bit toward the key back.
  • the design of the key channel has the same key:
  • the profiling of the key channel has two, from a common root on a key channel edge outgoing, V-shaped diverging ribs each with acute outer angles to the keyway flank, which are complementary to the two overlapping grooves of the flat key.
  • a sensing element is further provided in at least one cylinder core, which scans the edge, which results from the intersection of the two grooves of the flat key and which may also be formed as a flattening and blocked at too low lying edge or flattening the lock cylinder.
  • a sensing element is further provided which scans the presence of the undercut of a groove and blocks the lock cylinder in the absence of the undercut. This prevents that an undercut groove is replaced by a correspondingly larger, V-shaped groove.
  • the respective sensing elements are approximately radially displaceable or rotatable within the cylinder core and lie against the shoulder of the undercut of the keyway or to the edge or flattening between the v-shaped diverging grooves in the key.
  • a portion of the sensing element so that it fills the recess in the cylinder core on the lateral surface and a housing pin on the filled recess during the blocking process can slide over it.
  • a wrong key fits either not at all in the keyway or the housing pin in the plane in which the sensing element is, snaps into the then open recess in the cylinder core, so that this not further rotated (but probably turned back) can be.
  • FIG. 1 a key from the side
  • Fig. 2 the contour of a section along the line II-II in Fig. 1 with a first profile according to the invention
  • Fig. 3 the contour of a cut analogous to Fig. 2 with another profile according to the invention
  • Fig. 4 a cylinder core with inserted key according to the Fig. 1 and 2
  • the Fig. 5 and 6 show sections along the planes V and VI in Fig. 4 ,
  • a key 1 (flat key) of a locking system has a profile in cross-section, in particular a guide profile with grooves 2, 3.
  • a guide profile fulfills the task of positioning the key in the keyway.
  • the two grooves 2, 3 overlap (cover) each other.
  • the piercing direction X for producing the groove 2 and the piercing direction X 1 for producing the groove 3 are different. Thus one can not close from one piercing direction to the other piercing direction, which would facilitate measuring the key.
  • the grooves 2, 3 are undercut, in opposite directions. (That is, if one draws the angle X and X 1 between the piercing direction and the longitudinal center plane of the key so that they are smaller than 90 °, then the angle X is measured in the direction of the key back, while the angle X 1 measured toward the key bit.
  • the center 4 of the groove 2 (and thus its depth) is not determined by scanning normal to the longitudinal center plane 6 of the key, which makes determining the exact data of the groove 2 (ie width, depth, position and angle X) essential difficult. Not even the transition region 4 'from the flank to the groove bottom is detectable.
  • FIG. 2 Further Trognuten 40 and 41 between the overlapping grooves 2, 3 and the toothed key breast (the key bit) are shown in dashed lines. These are part of a variation profile that results from the existence or omission of individual grooves in the system or represented raster of all these possibly also overlapping trough grooves 40 and 41, respectively. Due to the aforementioned angular formation of the flutes, a surface structure can be achieved without disturbing sharp edges.
  • Fig. 2 also shows the istsprofilnut 42 whose groove bottom overlaps with the groove bottom of the groove 2, so that the keyway prevents the insertion of a wafer for scanning purposes in complementary complementary training. This overlapping here means exceeding a plane parallel to the longitudinal center plane 6 tangential plane at a groove 2 by another opposing groove 42nd
  • Fig. 3 shows a key 1 ', which in addition to the grooves 2 and 3 also grooves 2' and 3 ', which have analogous geometric properties as the grooves 2 and 3.
  • the edge is flattened within the grooves 2 'and 3' to a support surface 5 '.
  • Fig. 4 is the corresponding cylinder core 9 with a key 1 according to the Fig. 1 and 2 or 3 shown.
  • Essential are the two sensing elements 11 and 12, in the Fig. 5 and 6 can be seen more clearly.
  • the two sensing elements 11 and 12 are guided in a corresponding recess of the cylinder core 9 so that they move normal to the longitudinal center plane of the key 1, but can not tilt significantly.
  • both sensing elements 11 and 12 one end is free (the lower end, as in FIGS Fig. 5 and 6 seen), the other end is applied to the key 1, namely the sensing element 11 at the edge 5 (bearing surface 5 ') and the sensing element 12 at the undercut 8.
  • these sensing elements 11 and 12 are outside of the cylinder core depressions 21, 22nd , 31, 32, which slowly become deeper from the outer sides of the scanning elements 11, 12 and terminate in the central region of the scanning elements 11, 12 in a step 21 ', 22', 31 ', 32'.
  • These depressions lie in parallel cross-sectional planes in which pin tumblers are provided in the cylinder housing.
  • the cylinder core If the cylinder core is rotated so far that the housing pins reach the area of these recesses, then they slide with a correct key on the sensing elements 11 and 12 over the respective stage 21 ', 22', 31 'and 32' away. If the key is not correct, ie if the edge 5 or the support surface 5 'is too deep or the undercut 8 is not present, the scanning elements 11, 12 release the recesses.
  • the springs of the housing pins press the housing pins into the respective recess 21, 22, 31 or 32 so that the housing pins rest against the respective step 21 ', 22', 31 'or 32' and the cylinder core 9 can no longer be rotated ,
  • the cylinder core 9 can be turned back and not remove the appropriate keys. This works in both directions, even with double-locking cylinders built in the other way around.
  • the grooves 2, 3 are too weak in a key copy, i. too narrow or too shallow, then the key can not be introduced into the keyway because of collision with the corresponding ribs in the keyway of the cylinder core 9.
