Definitions

  • the invention relates to a key and rotary lock cylinder according to the preamble of independent claim 1 and a key for a rotary lock cylinder with an additional one Tumbler.
  • Keys of this type have the advantage that they are due of the control element arranged in the shaft is hardly unauthorized can be copied and thus with such keys equipped locking systems have a higher security value have.
  • the so far known keys of this Genus also called “mechanical keys”, are however still has various disadvantages, so that despite the very high copy security these keys, especially as Reversible key, have not yet been widely used.
  • DE-A-35 17 660 is a key of this type became known in the key channel of a rotary lock cylinder is insertable and one in its flat shaft Movable device with an additional tumbler is movable into the release state.
  • the moveable Setup of the key consists of a protruding one Pen that slides in a blind hole of the key is held.
  • a spring is also arranged in the blind bore, which pushes the pin outwards, the falling out of the pin by gradations in the blind bore of the Shank and on the pin is prevented.
  • Protruding pins are generally disadvantageous for a key because the key hangs easily on the pin.
  • the loosely slidable pin usually stands with one end on the shaft in front so that the key can hook in here too.
  • the generic FR-A-1 036 572 discloses a rotary lock cylinder with a key that has a cross section has a round shaft in which a pin is slidably mounted is for positioning a slide mounted in the rotor from an additional guard locking of the rotor when rotating the rotor is moved.
  • the slide arranges a counter bolt of the housing. The rotor stops when the rotor is turned further additional tumbler the slide against a spring force in the offset position.
  • a key and rotary lock cylinder of this type is also available become known by the generic EP-A-0 472 495.
  • the Additional guard locking is provided by a key shaft categorized slidably mounted pin, the outside is flush with a narrow side of the key. The verification of the control is done here with a locking element that the Shear line between stator and rotor exceeds.
  • the invention has for its object a key and To create rotary lock cylinder of the type mentioned on the outside of the shaft no recesses for a Rotary lock cylinder arranged ramp needed and still is easy to manufacture and has higher copy security.
  • the object is achieved by the invention according to claim 1.
  • the control element can be on the outside be exactly flush with a narrow side of the key so that such a key only upon closer inspection of such a key can be distinguished without control. Missing one copied key an appropriate control, so when inserting the key shaft into the key channel Guard locking of the rotor is moved radially outwards into the blocking position. The rotor cannot turn now and therefore the lock cannot be opened. Knows the key instead of the control element a hole in the corresponding one On the outside of the key, the guard locks the locking cylinder when this tumbler after a certain rotation of the rotor a counter bolt in Stator has reached. This counter bolt is then due to missing control element not classified and locks through an engagement in the recess of the rotor, the rotary lock cylinder.
  • the rotary lock cylinder is comparatively simple and therefore inexpensive to manufacture.
  • the additional measures on the stator are comparatively simple because they are only on the inside a conical recess must be worked into the stator.
  • the locking of the rotor can be a simple bolt be the one without spring loading in a blind bore of the rotor is guided radially.
  • the stator has one Insert on which the said recess for the with the Control has cooperating tumbler.
  • the deposit can be made of hardened steel or hard metal easily manufactured, reducing security against a violent opening of the rotary lock cylinder considerably is improved.
  • FIG. 1 shows a stator 3 with a conventional steel sleeve 4 and a housing 5, in which a rotor 1 is rotatably mounted is.
  • a rotor 1 With one inserted in a key channel 2 of the rotor 1 Keys 7 are not shown here, common tumblers classified, the rotor 1 for actuating a lock not shown here can be rotated.
  • Key 7 shows the classification of these usual tumblers appropriate blind holes.
  • the key 7 can, however also be a so-called wrench, in which case the rotary lock cylinder adjusted accordingly, of course is.
  • the housing 5 of the stator 3 be made from fins 30 soldered together.
  • the fins 30 are preferably made of hardened steel.
  • At the rear end of the housing 5 is a part-circular in the upper region Recess 29 provided in which an arcuate Insert 6 made of preferably hardened steel or hard metal is.
  • the insert 6 has a conical blind bore 6a on, which cooperates with a tumbler 15 of the rotor 1.
  • the housing 5 also has longitudinal channels 25 into which known slider 19 are used, in which housing pins 16 are guided with their springs 20 in bores 31. Such slide 19 are known per se.
  • the rotor 1 is provided with a radial bore 28, in which inserted a sleeve 13 with a through hole 14 is.
  • a tumbler 15 in the form of a cylindrical bolt guided radially.
  • the radial outer end of the tumbler 15 has a conical surface 15a, which correspond to the bore 6a of the insert 6 is.
  • a cylindrical arranged at the other end of the tumbler 15 Part 15c protrudes through or into opening 14 of the sleeve 13. As FIG. 1 shows, one is in the key channel 2 introduced key 7 the tumbler 15 by a control 10 pressed radially outwards against the insert 6.
  • the key 7 preferably has two control elements 9 and 10 on that in a continuous stepped bore 8 on the front End of the key shaft and are used with a common compression spring 12 in the positions shown in Fig. 1 are held.
  • the two control elements 9 and 10 are cylindrical Pins with one radially protruding outwards Flange 9a or 10a.
  • the flange 9a lies on a shoulder 8a of the stepped bore 8, thereby preventing the control element 9 at the outer end from the stepped bore 8 can emerge.
  • the flange 10a of the control element 10 lies accordingly on a sleeve 11, which with a press fit in the stepped bore 8 is inserted.
  • they are Control surfaces 9b and 10b of the elements 9 and 10 in the in FIG. 1 shown positions exactly flush with the narrow sides 7a the key 7.
  • the mechanical control device with Elements 9 and 10 and the compression spring 12 is comparative easy to manufacture and reliable.
  • the controls 9 and 10 can against the retroactive Force of the compression spring 12 limits inward into the stepped bore 8 are moved.
  • the purpose of this agility is from the following functional description.
  • the shaft of the Key 7 inserted into the key channel 2 as usual.
  • the tumbler is also 15 raised by the control element 10 so that it is in the recess 6a of the insert 6 engages.
  • the control element 9 which would raise the tumbler 5 accordingly. Because now the tumbler 15 and the control against the retroactive Force of the compression spring 12 can be moved inwards despite the engagement of the tumbler 15 in the recess 6a of the rotor 1 can be turned with the key, for example in Fig. 1 counterclockwise.
  • the tumbler 15 is not in engagement with the insert 6 and accordingly, the rotor can be classified according to the rest Tumblers are temporarily turned. After a turn of rotor 1 by 90 ° clockwise or counterclockwise, in this case, however, the counter bolt 16 falls inside the sleeve 13 and locks the rotary lock cylinder. The rotor 1 cannot be turned into position in this case in which the lock is unlocked. Is an inventive and key provided for the rotary lock cylinder 7 used, the counter pin 16 is by the tumbler 15 classified and the rotor can thus be more than 90 ° to the position in which the lock unlocks is.
  • the compression spring 12 is formed stronger than the compression spring 20, which the counter pin 16 radially inwards presses.
  • the counter pin 16 has a conical bore 22, which corresponds to the surface 15a the tumbler 15 is formed.
  • the opposite one Counter bolt 17 with the bore 23 and the compression spring 21 performs the exact same function. 2 is clear shown as the counter bolt 16 by the tumbler 15 arranged at a corresponding rotational position of the rotor 1 becomes. If the rotor 1 continues to rotate from this position, For example, counterclockwise, the guard locking will give way 15 in turn radially inwards, correspondingly also the control element 10 against the retroactive force of the compression spring 12 is moved radially inwards.
  • the rotary lock cylinder with an associated and according to the invention Key 7 can be operated as usual. At a However, a key with a missing control is an actuation not possible even when using high forces.
