Definitions

  • the invention relates to a key and rotary lock cylinder according to the preamble of independent claim 1, a key for a rotary lock cylinder with an additional tumbler and a rotary lock cylinder for a key that has a control element in the shaft.
  • a key and rotary lock cylinder of this type is known in the prior art from DE-A-35 17 660. In the rest position, the key has protruding and movable bodies in the narrow sides of the shaft, with which corresponding tumblers of the locking cylinder can be classified. Similar keys are also known from DE-A-34 24 307.
  • Keys of this type have the advantage that, owing to the control element arranged in the shaft, they can hardly be copied unauthorized and therefore the locking systems equipped with such keys have a higher security value.
  • the keys of this type also known as "mechanical keys", which have become known, are still subject to various disadvantages, so that despite the very high level of copy security, these keys, in particular as reversible keys, have not yet found widespread use.
  • a further key has become known from US-A-4,667,495, which has a pin which can be displaced to a limited extent in order to arrange the additional tumbler in the shaft.
  • the pin moves onto a ramp arranged in the rotor, which moves the pin radially and thereby classifies the additional tumbler. So that the ramp can reach the pin when the shaft is inserted, grooves or other recesses are required on the shaft, which limit the area available for control bores with a flat key.
  • the pin must therefore be placed as close as possible to the front end of the shaft.
  • the loosely movable pin usually protrudes with one end on the shaft so that the key can hook here.
  • a key of this type is also known from EP-A-202 949.
  • the additional guard locking is also arranged here by a pin that is mounted to be displaceable to a limited extent in the key shaft, so that the above-mentioned difficulties also exist in this case.
  • the invention has for its object to a key and a rotary lock cylinder of the type mentioned create that offers a higher security against manipulation.
  • the object is achieved by the invention according to claim 1, wherein the key is the subject of claim 6 and the rotary lock cylinder is the subject of claim 11.
  • the rotary lock cylinder shown in FIG. 1 has a rotor 3 with a key channel 4, a stator 2 and a steel sleeve 5 in the usual way.
  • a reversible key to be inserted into the key channel 4 conventional pin tumblers, not shown, are arranged, after which the rotor 3 can be rotated to actuate the lock, not shown here.
  • the associated key 16 according to FIG. 5 has holes 35 on the broad sides and narrow sides.
  • the key can also be a wrench, in which case the rotary lock cylinder is of course designed accordingly.
  • the rotary lock cylinder has a further tumbler 10, which is classified by the control element 19 shown in FIG. 4.
  • This additional control element 19 has a core pin 13 mounted in a radial bore 8 of the rotor 3 and a housing pin 12 mounted in a bore 9 of the stator 2 as well as a spiral spring 11 supported on the sleeve 5.
  • the housing pin exceeds 12 the shear line 14 and thus blocks the rotor 3.
  • the rotor 3 is blocked by the usual other pin tumblers, not shown here.
  • a locking pin 6 is inserted into symmetrical bores 15 of the stator 2, which are also supported on the sleeve 5 and which exceed the shear line 14 with the front end.
  • Such a locking pin is shown in more detail in FIGS. 6a and 6b. 7 also shows how the narrower inner end 24 of the locking pin 6 engages in a circumferential groove 7 of the rotor 3.
  • the locking pin 6 can thus only move slightly in the radial direction, since it rests on the one hand on the sleeve 5 and on the other hand on the rotor 3.
  • the control element 19 shown in FIGS. 4 and 5 is inserted into a continuous bore 18, this bore being transverse to the longitudinal direction of the shaft 17 and parallel extends to the broad sides 36 of the key 16.
  • the control element 19 has two bolts 20, between which a compression spring 27 is arranged, which has a substantially higher spring force than the spring 11 of the additional tumbler 10.
  • the end faces 23 of the bolts 20 are flush with the narrow sides 30 of the shaft 17 and prevented from emerging from the bore 18 by sleeves 21 inserted into the bore 18.
  • the sleeves 21 are fixed, for example, by a press fit in the bores 18.
  • the spring 19 presses the bolts 20 at radially projecting stops 37 against a sleeve 21 which is stuck in the bore 18.
  • the mode of operation of the control element 19 is explained in more detail below with reference to FIGS. 2 and 3.
  • the key shaft 16 is inserted into the key channel 4 as usual.
  • the usual tumblers are classified as known.
  • the additional pin tumbler 10 is arranged by the control element 19 as shown in FIG. 2.
  • the core pin 13 rests on the end face 23 of the bolt 20 and is radial to the Release of the rotor 3 required height raised. Since, as mentioned, the spring 27 is substantially stronger than the spring 11 of the pin tumbler, the bolt 20 of the control element 19 is essentially not moved when the tumbler 10 is arranged.
  • the rotor 3 can be turned clockwise or counterclockwise with the key 16 used. As can be seen, the outer end of the core pin 13 engages in the circumferential groove 7 of the rotor 3.
  • a bolt 20 of the control element 19 is in contact with a locking bolt 6. If the rotor 3 is rotated further in the same direction of rotation, the bolt 20 is moved inwards by a wedge surface 39 of the locking bolt 6 against the restoring force of the spring 27. Since the bolt 20 can easily move inwards, the rotor 3 can be rotated further beyond the locking bolt 6 in the same direction of rotation and the bolt of the lock can be actuated.
  • the rotor 3 even if the additional tumbler 10 is arranged, can only be turned up to one of the locking bolts 6, since the core pin 13 does not deflect inwards can and is therefore on the corresponding locking pin 6.
  • a control element 25 is formed by a resilient arm 31, the free end of which can deflect inwards into a recess 32 in the key shaft 28.
  • the key can be a reversible key or a prong key.
  • two such control elements 25 are arranged symmetrically.
  • the resilient arm 31 is designed such that it can raise the core pin 13 radially outward against the force of the spring 11 to the required height in order to arrange the additional tumbler 10.
  • a control element 26 is formed by a resilient web 33 which covers a trough-shaped recess 34.
  • the two ends of the resilient web 33 are engaged in corresponding recesses in the shaft 29 or are soldered to the latter.
  • the web 29 is designed such that it can raise the core pin 13 to the required height in order to release the rotor 3, but that the core pin 13 can deflect inward when a locking bolt 6 is exceeded.
  • FIGS. 10a to 10e show a rotary lock cylinder 50 which can be operated with a key 16 described above.
  • This differs from the rotary lock cylinder 1 in that two additional tumblers 40 are arranged in the radial plane of the additional tumbler 10, each of which has a bolt 41 made of chromium-nickel steel in a radial bore 43 of the stator the spring 11 is pressed against the rotor.
  • These further tumblers 40 check the control element 19, 25 or 29 in order to thereby prevent manipulation.
  • the mode of operation of the further tumblers 40 is explained below with reference to FIGS. 10a to 10c.
  • the key 16 described above is inserted into the key channel 4.
  • the additional tumbler 10 and the usual tumblers, not shown here, are arranged so that the rotor can be rotated into the rotational position shown in FIG. 10b and finally into the rotational position shown in FIG. 10c.
  • the core pin 13 is pressed radially inwards against a pin 20 of the control element 19 by the bolt 41 of the additional tumbler 40.
  • the spring 27 is now harder than the spring 42 of the additional tumbler 40, so that the rotor can be rotated beyond this position and the lock can finally be opened.
  • a manipulation key 51 is inserted into the key channel and it is assumed that with this the usual tumblers and also the additional tumbler 10 can be classified. It is also assumed that the core pin 13 can be moved radially inward into a recess 53 of the key 51 to overcome the locking pin 6. If the tube now reaches the rotational position in which the bore 43 and the bore 44 are aligned, the bolt 41 is moved inwards by the spring 42 and engages in the bore 44 of the tube, which is thereby blocked and does not open the lock can be rotated further. 10e shows the arrangement in which the bolt 41 has crossed the shear line 14 and prevents the rotor from rotating further. The manipulation key 51 is also locked here and can no longer be removed from the rotary lock cylinder.
