Definitions

  • the invention relates to a cylinder lock with platelet tumblers and a key for the lock, which can be used in particular as a motor vehicle door lock.
  • a cylinder lock which has a cylinder housing in which a cylinder core is rotatably mounted.
  • the cylinder core has in its central region an axially extending key channel and perpendicular thereto radially extending, the cylinder core passing through guide slots.
  • In each guide slot sit in pairs adjacent to each other or axially adjacent and mutually and radially displaceable two each loaded with at least one spring, platelet-shaped from sheet metal stampings tumblers, so-called Platinum tumblers.
  • the platelet tumblers engage in their locked position with the key removed due to the spring load radially in the axial direction of the cylinder housing extending, radially opposite locking grooves, so that the cylinder core is non-rotatably in the cylinder.
  • the platelet tumblers are configured in the shape of a full frame and each have two frame longitudinal webs and two frame cross webs, which have a substantially rectangular, with the Key channel form axially aligned recess. On inner edges of the frame longitudinal webs inwardly projecting control cam are arranged.
  • the matching flat key has a substantially rectangular in cross-section key bit or central web with two broad sides and two narrow side surfaces, wherein mirror images opposite each other on the broad side surfaces each extending in the longitudinal direction of the key bit groove-like recess are provided with at right angles to the groove bottom aligned groove walls as Control edges or control tracks are formed, which cooperate with the correspondingly arranged control cam of the platelet tumblers.
  • the paired arrangement allows a simple way to use reversible keys, which are rotated by 180 ° about its longitudinal axis of the key bit inserted into the keyway and can operate the locking mechanism.
  • the platelet tumblers are withdrawn into the interior of the cylinder core against the respective spring force. Due to the known construction one can use high numbers of different platelet tumblers and thus ensure high numbers of variations of closures. In addition, a shorter space-saving design of the lock cylinder is possible.
  • such a cylinder lock still requires a relatively large cylinder core diameter of z. B. about 15 mm, so far as the space requirement is still not the wishes of users, for. B. the automotive industry corresponds.
  • Cylinder core diameters of less than 15 mm are possible with cylinder locks with platelet tumblers, which have the locking cams on the inner edges of the frame crossbars, with the control tracks on the narrow side surfaces of the key bit are trained ( DE-GM 76 37 619 ).
  • the disadvantage is the possibility of simple replica and a weakening of the key bit due to deep millings of the control tracks, which is why this type of cylinder lock with plate tumblers in motor vehicle doors despite small construction is no longer in use.
  • cylinder lock type with platelet tumblers and with a particularly high variety of variations of the control edges and strength of the flat key is z. B. from the DE 27 42 165 C2 known.
  • the cylinder core of the lock cylinder has mutually spring-loaded platelet tumblers on each other and the flat key is provided with oppositely directed to opposite narrow sides of the flat profile towards free, stepped incision paths or control tracks, which are separated from each other by a continuous key bit or middle web of the flat profile.
  • the flat key has a Z-shaped base profile with the central web, wherein the two incision paths or control tracks are arranged on the respective opposite to the narrow side of the flat profile inner surfaces of the two Z-legs.
  • the object of the invention is the variety of variations from the DE 27 42 165 C2 to increase known Zylinderments and nevertheless to use a reversible key for it.
  • a lock cylinder diameter of less than 15 mm with z. B. 8 platelet tumblers produce.
  • An inventive cylinder lock has a cylinder housing 1 with a cylinder wall 2, which can be designed externally arbitrary and z. B. may consist of plastic.
  • the cylinder wall 2 surrounds an axial cylindrical lock core recess 3 and into which at least one locking groove 4 extending axially parallel in the cylinder wall 2 and opening towards the recess 3 is inserted. If two blocking grooves 4 are provided, they are arranged diametrically opposite each other (FIG. Fig. 1 ).
  • a cylinder core 6 In the cylindrical lock core recess 3 of the cylinder housing 1 inserted around its central longitudinal axis 5 limited rotatably a cylinder core 6.
  • a cylinder core 6 In the cylinder core 6 is an axial key channel 9 and in the region of the key channel 9 are aligned transversely to the longitudinal axis 5 aligned chamber slots 7 introduced - in the example shown to Fig. 2
  • chamber slots 7 There are six chamber slots 7 - which are separated from each other by Wandungsstege 8 axially aligned.
  • Each chamber slot 7 has on one side a broadening, z. B. a blind hole 10, with a bearing stage 11, on which a compression spring 12 superimposed.
  • each chamber slot 7 sits a substantially rectangular frame-shaped plate tumbler 13 of z. B. a sheet metal stamped part, the two frame transverse webs 14, 15 and two longitudinal frame webs 16, 17 which form a substantially rectangular, the keyway 9 surrounding interior with a height "h” and a width "b".
  • a projecting in the plane of the sheet abutment nose 18 is disposed on the outside of the bearing stage 11, against which the compression spring 12 presses and which can be supported against the inner wall 19 of the cylinder wall 2 of the cylinder housing 1.
  • mounting slot 20 facilitates the assembly of the platelet tumblers 13 and the compression springs 12th
  • the cylinder core 6 has - as usual - at one end a driver 21 for a lock mechanism, not shown, and at the other end a particular serving as a stop on the cylinder housing 1 collar 22.
  • Each rectangular interior of the frame of the platelet tumblers 13, which is aligned with the keyway 9, has on one side beyond the halving line the height "h" or on one side of the longitudinal axis 5 enclosing, perpendicular or perpendicular to the frame longitudinal webs 16, 17 lying central longitudinal plane 25 (im in Fig. 1 shown example, the below the longitudinal plane 25) projecting into the interior of the frame control stage 24 in a z. B. the abutment nose 18 diagonally opposite corner region 23 between a frame crossbar 14 or 15 and a frame longitudinal web 16 or 17, wherein the control stage 24 extends at right angles to the inner edge of the frame longitudinal web 16 or 17.
  • Fig. 1 shows this embodiment with six in the axial direction of the longitudinal axis 5 successively sitting Platelet tumblers 13, wherein on the one hand (in Fig. 1 on the left side) three control stages 24 of three platelet tumblers 13 and on the opposite side (in Fig.
  • control stages 24 of three further platelet tumblers 13 are provided by stepped punches, wherein the Control stages 24 at different heights, calculated from the inner edge of a frame crossbar 14 or 15 are arranged. It is within the scope of the invention to arrange control stages 24 also projecting into the interior of the frame cams.
  • the blind holes 10 adjacent chamber slots 7 and thus the Ablagernasen 18 adjacent Platinum tumblers 13 are arranged diagonally opposite, with the result that the chamber slots 7 can be arranged closer together and the cylinder core 6 can be built short.
  • a reversible key 43 can be configured according to Fig. 3 a central, in cross-section rectangular, continuous, middle web or key bit 30 having a central longitudinal center axis 41, a height "h” and a width "b” and with two narrow edges 31, 32 and two broad side surfaces 33, 34 and a front edge 35.
  • the contours of the control tracks 36 and 37 are different from each other as well as the contours of the control tracks 36a and 37a with each other, but the contours of the control tracks 36a and 36 as well as the contours of the control tracks 37a and 37 are identical.
  • control tracks 36 and 37 are located on one side of the longitudinal plane 42 and the control tracks 36a and 37a on the other side of the longitudinal plane 42 each at an equal distance therefrom.
  • control tracks 36, 36a and the scatter tracks 37, 37a are diagonally mirror-inverted with respect to a mirror plane passing through the longitudinal center axis 41 of the central web 30.
