Definitions

  • the invention relates to a locking cylinder with a core rotatably mounted in the housing, in particular a profile cylinder, which has a profiled key channel for receiving a correspondingly profiled flat key and a plurality of radially displaceable core pins which can be acted upon by cuts on the chest side thereof and which interact with correspondingly arranged spring-loaded housing pins. and with a radially displaceable core, which engages in an inner circumferential recess in the housing and runs parallel to the axis, blocking the control elements which are movable in a plane transverse to the cylinder axis counter to spring action and protrude laterally into the key channel and can be acted upon by the flat key, or for their radial entry movement to be released into the core. Furthermore, the invention relates to a flat key suitable for this locking cylinder.
  • a lock cylinder of the aforementioned type is known from DE-A-30 14183, Fig. 13.
  • the control elements located between it and the key channel consist of spring-loaded scanning bolts, which are accommodated in corresponding stepped bores in the core and are provided with a beveled constriction on both sides, into which a circular cylindrical cross-section is obtained when the matching position is brought about by the appropriate flat key possessing locking bar can occur when the cylinder core is rotated.
  • this requires a still relatively stiff design of the control elements actuating the locking bar, because for their adjustment not only the sliding friction force of the scanning bolts, but also the static friction between their constrictions and the locking bar must be overcome.
  • this known locking cylinder with its scanning bolts either blocking or releasing the continuous control bar, offers, in addition to its conventional pin tumblers, an additional variation option, which is particularly desirable for locking systems.
  • a locking cylinder according to DE-B-20 03 059, the cylinder core of which contains, in addition to the core pins interacting with housing pins, additional locking pins which can be displaced transversely to the inserted flat key and which have thickened hemispherical heads in corresponding recesses in the Protrude inside the housing and thereby block the core additionally.
  • these locking pins can enter these recesses when a suitable key is inserted, which is provided with dome-shaped recesses in profile thickenings on both sides, and thereby enable the core rotation.
  • the locking pins are acted upon directly by the flat key here, they can easily leave pressure marks in the key when the wrong key is used when the core is twisted, whereby their positions in the cylinder are revealed and the wrong key can be corrected accordingly.
  • these additional locking pins fail if the false key is milled flat in the locking pin area or if a false key with a correspondingly narrower shaft profile is used from the outset. Otherwise, the dome-shaped cutouts intended for the locking pins are already in the transition area to the key incisions, which can easily lead to correspondingly disruptive overlaps.
  • the invention is based on the object to improve and perfect a lock cylinder of the type mentioned in that he solid, failure-prone and wear-resistant design has even greater security against unauthorized unlocking and key falsification with increased variation options and, above all, enables easier actuation or twisting of the cylinder core when using the appropriate flat key. It should also be ensured that such locking cylinders can easily be retrofitted in existing conventional locking systems in order to expand the latter accordingly.
  • control elements are designed as two-armed control levers which are tiltably mounted on a common axle bolt running parallel to the key channel and whose ends facing away from the key channel interact with the locking bar, at least one of which the control lever is designed as a counter-blocking lever that blocks or releases the blocking strip in opposite directions.
  • the control levers lying one behind the other in the key channel direction and bearing on the correspondingly running axle pin with low friction can be pivoted comparatively easily into their position releasing the continuous locking bar for the rotation of the core by means of the suitable flat key.
  • At least one of the control levers is designed as a counter-control lever, which, like the control levers, cannot be brought into the tilting position releasing the locking bars by a correspondingly located lateral recess in the flat key, but rather by a position in the key located at a corresponding point , consciously not existing lateral recess must be tilted in the opposite direction.
  • This brings an additional unlock protection against possible flat grinding of the key at its longitudinal center containing the side depressions.
  • the tiltable control elements block the core even in its rest position when the flat key is inserted, which is not provided with proper lateral recesses, i.e.
  • control levers are provided at their ends projecting into the key channel with control lugs which can be varied in the axial direction and have different profiles.
  • control levers provide an additional third variation option in addition to the two other variation options provided by the tumbler pins on the one hand and the profiling of the key channel on the other.
  • control levers are advantageously accommodated in segment-milled receiving slots in the cylinder core and are themselves designed in the manner of a disk segment, with their curved rear surface facing the cylinder housing wall and with their chest surface extending straight up to the projecting control nose, facing the key channel, a correspondingly arranged bearing hole for the through axle bolt and underneath have a recess for a compression spring located therein, which is supported on the bottom of the receiving slot of the cylinder core, and are provided at their lower end with a control edge for the locking bar, which has a radially projecting blocking cam. While the radially projecting blocking cam is on the outside of the control levers, it is on the inside of the counter-control levers.
  • the flat key belonging to the lock cylinder designed according to the invention is from the z. B. by the already mentioned DE-B-20 03 059 known genre insofar as its shaft is provided with profile ribs and grooves present on both sides, has a continuously broad guide back and incisions on the opposite chest side for arranging the cylinder core pins and laterally located Has recesses for engaging additional locking elements of the cylinder core.
  • the lateral depressions consist of circular segment-shaped millings which are concentric to an axis extending parallel to the key axis and which lie outside the incision area near the back of the key.
  • the lateral millings are advantageously provided in the profile hump adjacent to the guide groove of the key, which is opposite a profile trough on the other side of the key.
  • the flat key is deliberately weakened so far that it is still of sufficient strength on the one hand due to the normal profile thick points remaining between the cutouts, but on the other hand it would be too thin and thus unusable in the event of any longitudinal surface grinding in this cutout area.
  • the counter-control lever or levers can also be provided with a built-in permanent magnet at their control nose end, the associated flat key containing one or more built-in permanent magnets at the corresponding points instead of the milled grooves otherwise present there, each corresponding to the Cylinder core on its counter-control levers located opposite magnets are poled opposite.
  • the flat key is inserted into the key channel of the locking cylinder, there is a corresponding repulsive tilting movement of the counter-control lever, which is thereby able to release the locking bar which would otherwise be blocked by it.
  • the profile lock cylinder shown in FIGS. 1 to 4 and 6 has a cylinder housing 1 with tumbler pins 2 which are displaceably mounted in its profile web 1 'in corresponding bores 1' and are under spring tension 2.
  • the core 3 is rotatably mounted in the housing 1 radially running bores 3 ', the core pins 4, which cooperate with the housing pins 2, are displaceably mounted.
  • the profiled key channel 5 is provided in the core 3, which is used to insert the correspondingly profiled flat key 6, which with its conventionally wide-area, continuously smooth running, rounded back 6 'finds a well-guided receptacle in the correspondingly profiled, non-narrowed peripheral section 5' of the key channel , 4 can be classified so that they come with their mutual contact into the separating cylinder surface 7 between the core 3 and the housing 1, whereby the core 3 would lose its blockage in this regard.
  • control levers 8 lying one behind the other in its longitudinal direction, which are accommodated in receiving slots 3 ′′ of the core 3 which are milled out in segment form and are themselves designed in the manner of a segment of a disc a common axle bolt 10 which runs parallel to the key channel 5. They protrude with their upper ends, which are designed as control lugs 8 ', into the key channel 5 near its undiminished peripheral section 5', here directly below the relevant guide rib 5 "into the key channel 1, in which they are held by the compression spring 11 "located in its recess 8", which is supported on the bottom 3 '"of the receiving slot 3".
  • the control levers 8 of the cylinder housing wall rest with their back surface facing while ih right up to the control lugs 8 'rectilinear breast surfaces the key channel 5 or the slot bottom 3 "' are facing.
  • the receiving slots 3 " are offset from the core pins 4, so that the latter can be supported when the core 3 is rotated on the partition walls 14" between the slots 3 ".
  • control levers 8 are provided with a control edge 8 ′ ′′ which merges outwards into the radially projecting blocking cams 8 1v .
  • the control levers 8 work together with a common axially parallel locking bar 12, which in substantially rectangular cutouts 13 in the partition walls 14 of the core 3 are supported so as to be radially displaceable to a limited extent.
  • This locking bar 12 normally protrudes into the curved recess in the inner wall of the housing 1 and correspondingly parallel to the axis of the recess 15.
  • a further appropriately designed locking recess 15 ' is provided on the opposite side of the housing 1.
  • At least one of the control levers described above is designed as a counter control lever 8a.
  • counter control levers 8a shown 3 and 4 differs from that shown in Fig. 1 and 2 illustrated control lever 8 only in that its situated at the lower end blocking cam 8 1v is not outside but inside. This has the consequence that this blocking cam 8 IV wherein in Fig.
  • the control levers 8 on their control lugs 8 ′ projecting into the key channel and consequently interacting with the inserted key 6 can be correspondingly differently profiled in the axial direction, the lateral milled portions 6 ′ ′′ in the key 6 being in 5 and 6, this profile can be varied or shifted accordingly.
  • the side depressions 6 "'consist of Key 6 made of circular segment-shaped millings which run concentrically to an axis extending parallel to the key axis and which lie outside the incision area 6 ′′ in the vicinity of the key back 6 ′.
  • the key 6 is otherwise with profile ribs 6 v or profile grooves 6 V1 to be varied provided the profiling of the key channel 5 e speak.
  • the lateral millings 6 "'advantageously lie in the profile boss 6 VIII adjacent to the guide groove 6v" of the key, which is opposite a profile recess 6 IX on the other key side (FIG. 1).
  • a permanent magnet 16 is installed on the counter control lever 8b at the control nose end thereof, which may have the north-south polarity indicated by the letters S, N.
  • a permanent magnet 17 is also a permanent magnet 17, but of opposite polarity.
