Definitions

  • the invention relates to a locking device, especially for motor vehicles, with a locking cylinder and a key, the locking cylinder comprising at least one cylinder housing with at least one locking channel and a cylinder core with tumblers.
  • Locking devices of the type mentioned are known in a wide variety of embodiments and are installed in doors, flaps and steering columns of motor vehicles. Furthermore, these locking devices are also used in many other cases.
  • a locking device of the type mentioned in which the tumblers are each formed by an approximately circular disk with a segment-like flattening and a diametrically opposed circumferential area with teeth, with which a row of teeth on the key Kind of a rack cooperates in order to turn the disk, which is biased by a spring into the locking position, about an axis running transversely to the key insertion direction into the release position, in which the flattening faces the locking channel, so that the disk no longer when the key is inserted into the key channel engages in the blocking channel.
  • this locking device already has the features a to d of claim 1.
  • Tumblers can therefore not be moved in a straight line to the key channel, but rather they can be pivoted and engage in the blocking position with at least one nose on their circumference in the blocking channel or lie with their nose outside the blocking channel, so that the cylinder core is freely rotatable.
  • the tumblers are controlled using the key via recesses and switching teeth or control teeth, which allows the design of new types of keys and thus offers a wide variety of variations.
  • a locking device 1 according to FIG. 1, which is intended in particular for use in motor vehicles, comprises a locking cylinder 2 and a key 3.
  • the locking cylinder 2 includes a cylinder housing 4 with locking channels 5 and a cylinder core 6 with tumblers 7a, 7b, 7c and 7d .
  • the tumblers 7a to 7d are each mounted in the cylinder core 6 so as to be movable about an axis 8. Furthermore, at least one protruding driver 9 or a recess 10 is provided on the key 3 or on each of the tumblers 7a to 7d for transmitting the straight-line key movement into a movement of the tumblers 7a to 7d about its axis 8.
  • the protruding driver 9 is located on the key 3 or on the key shaft 11 thereof, while a recess 10 is arranged on each of the tumblers 7a to 7d.
  • a recess 10 is arranged on each of the tumblers 7a to 7d.
  • two switching teeth 12 are provided on the circumference 13 of each tumbler 7a to 7d, as can be seen above all from the illustration on an even larger scale in FIG. 4.
  • the tumblers 7a to 7d also have at least one nose 14 or 15 which can be pivoted into the blocking channel 5 on their circumference 13 (FIG. 4). These lugs 14, 15 are arranged diametrically opposite the recess 10 or the shift teeth 12.
  • the tumblers 7a to 7d are pivotable about the axes 8 and cannot be freely rotated. Furthermore, the tumblers 7a to 7d are acted upon by a torsion spring 16 (FIG. 4), which presses the tumblers in each case into the blocking position, so that the tumblers must be pivoted against the spring force from the blocking position into the release position using the key 3.
  • a torsion spring 16 FIG. 4
  • the cylinder core 6 has pockets 17 which are open radially outwards and serve to receive the tumblers 7a to 7d.
  • the tumblers 7a to 7d are pivotally mounted in the pockets 17 and, in the locked position according to FIG. 1, only reach out of the pockets 17 with their lugs 15. 2, the tumblers 7a to 7d lie with their noses 14 and 15 in the pockets 17 and take one with the circumference 18 of the Cylinder core 6 flush position.
  • Tumblers 7a to 7d and pockets 17 are thus provided in more than one plane 19, 20, preferably four tumblers 7a to 7d lying in a total of two radial planes 19, 20.
  • the key 3 has a single projecting driver 9 in the form of a control tooth 9.
  • this control tooth 9 engages on the switching teeth 12 of the tumblers 7a to 7d or runs into the recess 10 between the two switching teeth 12 and adjusts the tumblers during the linear movement up to a stop 22 7a to 7d and brings them into their release position according to FIG. 2.
  • the situation shortly before the control teeth 9 enter the key 3 into the recesses 10 of the tumblers 7a to 7d is shown in FIG. 1, taking into account the permutation options and the variety of variations, the four control teeth 9 can be arranged in different key levels 23.
  • the recesses 10 and the switching teeth 12 are always provided at the same location on the circumference 13 of the tumblers 7a to 7d.
  • the lugs 14 and 15, on the other hand, are arranged on the tumblers 7a to 7d in the case of different tumblers 7a to 7d and, owing to the permutation possibilities with one another and with respect to the switching teeth 12.
  • Each tumbler 7a to 7d has two lugs 14 and 15 in the illustrated embodiment. Not only a single locking lug is provided, so that even if the wrong key is used or if e.g. the tumblers are pivoted with the aid of a toothed rack, the second tooth still closes when the first tooth is in a release position.
  • the axes 8 for the tumblers 7a to 7d are located on inserts 24 which can be inserted into corresponding recesses 25 in the cylinder core 6.
  • the insert 24 is at least partially of the same shape as the cylinder core 6, the free ends of the axes 8 also lying in cylindrical passage openings 26 of the cylinder core 6 according to the exemplary embodiment.
  • the tumblers 7a to 7d can have recesses 10 or switching teeth 12 in more than one plane 27 (for a non-reversing key).
  • Recesses 10 and shift teeth 12 are preferably located in two levels 27 (FIG. 3), and accordingly control teeth 9 are arranged on more than one level 27 on the key 3 for such tumblers.
  • each tumbler has only a single recess 10 and, accordingly, two switching teeth 12.
  • FIG. 5 shows a modified embodiment or only a broken-off piece of the cylinder core 6 with the tumbler channel 21 and the pocket 17, in which a tumbler 7b 'is pivotally mounted on the axis 8.
  • a tumbler 7b ' is pivotally mounted on the axis 8.
  • the key 3 ' only the end adjacent to the key tip 28 is also shown in FIG. 5.
  • the embodiment according to FIG. 5 differs from the locking device 1 according to FIGS. 1-4 in that the tumbler 7b 'has at least one driver 9' projecting over its circumference 13 in the form of control teeth 9 'and the key 3' each one Have driver 9 'of the tumbler 7b' associated recess 10 '.
  • the protruding driver 9 ' is therefore not on the key 3', but on the tumbler 7b 'and accordingly the recess 10' is no longer arranged on the tumbler 7b 'but on the key 3'.
  • the recess 10 ' has a relatively large, free length. This is necessary since, according to the exemplary embodiment, a second driver 9 'must also lie in this recess 10 when the tumbler 7b' is in the release position.
  • FIGS. 6 and 7 parts corresponding to the parts explained with reference to FIGS. 1 to 5 are provided with a double line after the reference symbol. 6 so that the tumblers 7a to 7d and 7b do not press the key 3 or 1 ′′ out of the key channel on account of the torsion springs 16 acting on them and 7 a latching element 30 ′′ is provided in the form of a spring element.
  • the locking element 30 ′′ comprises a spring bar 31 ′′ which is arranged in a freely resilient manner and which carries a locking lug 32 ′′.
  • the locking lug 32 ′′ protrudes on the key side beyond the spring bar 31 ′′ and is able to bridge a spring travel f according to FIG.
  • the catch element 30 ′′ preferably lies continuously with its circumference in a recess 33 ′′ of the cylinder core 6 ′′ and has a recess 34 ′′ behind the spring bar 32 ′′ in order to achieve the spring property.
  • the recess 33 ′′ in the cylinder core 6 ′′ extends with a passage opening 35 ′′ for the locking lug 32 ′′ into the key channel and is delimited by two wall elements 36 ′′ and 37 ′′ according to FIG. 6 for mounting the locking element 30 ′′ .
