Definitions

  • the invention relates to a locking device with a cylinder housing and a cylinder core mounted therein locking cylinder and with a keyway in the cylinder core retractable flat key, which either on at least one broadside or on a projecting over the broad side high rib a plurality of recesses arranged in a row has, which can have a predetermined by the locking system maximum depth, in which recesses enter the tip portions of core pins two-piece, sprung in the cylinder housing Zuroiss reconstructe.
  • a locking device of the type in question is known from the DE 26 584 95 C2 in which the flat key shown there is designed as a reversible key. This has on its broad sides, the row-shaped successively arranged recesses for arranging the tumbler pins. When properly arranged the two-piece tumbler pins by means of the associated flat key, the joints between core pins and housing pins at the height of the fulcrum of the cylinder core, so that the closing rotation can be made by means of the flat key.
  • a flat key is known for a lock cylinder which cooperates with tumbler pins arranged in a double row, which cooperate with ribs projecting from the broad side of the key.
  • the DE 38 32 143 A1 describes a flat key with a broadside profiling, which are scanned by the tips of housing pins of tumbler pairs.
  • EP-A-1 057 953 is a lock cylinder and associated key known wherein in the cylinder core lying transversely to the broad side of the keyway in a row one behind the other, a tip with adjoining cylinder portion having tumbler pins, which offset in particular featherless supplementary pins offset gap.
  • the key has on opposite broad sides arranged recesses for the placement of tumbler pins and supplementary pins, wherein at least one Pin associated pin and a common complementary pin associated depression penetrate a common, parallel to the key width surface extending plane.
  • each recess row is assigned a rib projecting over the key area, in the cross-section of which at least one of the pins dips. Furthermore, it is provided that the deepest reaching depression is closest to the vertex of the rib and that several depressions of a depression row are combined to form a continuous groove with different groove base level, the maximum groove width corresponding to the diameter of the tumbler pins. As a result, an increased number of normally large incremental steps without appreciable weakening of the key shank is to be produced in a production-wise simple manner.
  • the object of the invention is based on the object, a generic closure device ausgestalten so that the aforementioned opening method is not vorlangbar.
  • a generic locking device of increased safety value is created. Attempting to deepen the wells beyond the maximum depth to use the percussion technique mentioned above may result in some wells missing the bottom and open holes throughout. This occurs, for example, when the locking system requires an emanating from the key tip, the lower rib detecting smaller thickness. If such a flat key, which then serves as an unlocking element, is inserted into the keyway, the corresponding core pin (s) enters with its or their pointed cross-section reduced cylinder sections into such openings or holes and thus catch the key. A forward or backward displacement of the key, be it by train or impact is then not possible. The flat key is thus fixed in the key channel.
  • the core pins containing the tip-near, cross-section-reduced cylinder portion are assigned to the keyway inner region, so that these specially designed core pins are "in the shadow" of the upstream core pins and therefore can not be examined with regard to their design.
  • the advantage here is that the locking device can largely retain the proven structure, which also makes it possible to achieve the increased safety value largely without additional costs.
  • the cylinder core has at least one Zuroisslixen opposite arranged additional pin, the tip of which projects in the release position in the tie rib associated cross section of the keyway and that the tie rib is reduced in height from the key tip to this additional pin or missing.
  • the relevant additional pins force down the height of the tie rib from the key tip. If the height reduction or absence of the deep rib is not provided up to this additional pin, the key or a suitably designed Entsperrelement can not be introduced. Due to the reduction in height or the absence of the deep rib up to the corresponding area, the reason for the cuts, which extend beyond the lowest incision value of the system, is the reason why passages are created there.
  • the flat key belonging to the closing device has in one version a two opposing broad sides forming key shank. At least one wide side has in key shank longitudinal extent in rows successive recesses for the entry of the tip portions of the core pins, which depressions may have a predetermined by the locking system maximum depth. The other broad side is provided with the tie rib for forming the bottom of the maximum depth having recess.
  • the flat key is characterized in that the tie-rib is at least opposite to the height in réelleeinsteckraum first recess designed or missing.
  • any depressions exceeding the maximum depth receive the form of passage openings for the specially designed core pins. It is possible to reduce the depth rib in one or more stages.
  • An additional concealment with regard to the incision depth results from the measure of providing a deep rib opposite the raised rib, which extends in particular only over a partial length of the key shank longitudinal extension, optionally at different heights. It is thereby possible to provide the permutation of corresponding lengths of the key shank in different planes.
  • an alternative solution is characterized in that the broad side or the raised rib flank facing away from the depressions has at least one catch opening coaxial with its recess, wherein the depth of the recess necessary for arranging the associated tumbler pin is less than the lowest possible cut value and the catch opening depth is selected in that it penetrates the bottom of the depression deepened to the maximum depth. Its function as a catch opening receives this only when the opposite depression experiences the lowest possible incision depth. Then catch opening and deepened to the maximum depth deepening and thereby create the possibility that the key insertion of cross-section reduced cylinder portion of the core pin concerned can occur and hereby catches the key.
  • This concept according to the invention can be used with a flat key which arranges the tumbler pins with depressions arranged on its broad side. Also, such a version can be chosen that the flat key from its narrow side outgoing recesses forms for corresponding tumbler pins. Parallel to these, the lock cylinder includes additional tumbler pins whose core pins cooperate with depressions of the raised edge.
  • the catch opening in question on the raised rib flank can be made for example by a cutout, which transverse to the broad side of the flat key by means of a Milling cutter is milled.
  • the in the Fig. 1 to 18 illustrated, as a whole with the numeral 1 designated closing device according to the first embodiment has a lock cylinder 2 and a flat key associated with this 3.
  • the lock cylinder 2 is formed as a half-cylinder. However, it is also possible to create it in the form of a double cylinder.
  • the lock cylinder 2 has a cross-sectional profiled cylinder housing 4, which is composed of a circular-cylindrical section 4 'and a flange section 4 "extending radially thereto.Nearby its one end, the cylinder housing 4 is equipped with a cut-out 5 projecting from the circular-cylindrical section 4' The latter is in driving connection with the inner end of a cylinder core 7, which is rotatably arranged in a core bore 8 of the cylinder housing 4.
  • the aforementioned core bore 8 is located in the circular cylindrical section 4 'of the cylinder housing receives the cylinder core 7 on the one hand by a lying within the cutout 5 Circlip 9.
  • the cylinder core 7 forms a larger diameter collar 10 at christleinsteck constitutionalen end of the cylinder core. 7
  • the cylinder core 7 In the horizontal longitudinal center plane of the cylinder core 7 includes a cross-sectional profiled keyway 11, one narrow side of the Kerncardfuge F is open. Transversely to the keyway 11, the cylinder core 7 and the cylinder housing 4 each form aligned core and housing bores 12, 13, which bores extend in the lock cylinder longitudinal center plane. The core bores 12 open into the keyway 11.
  • the holes 12, 13 are designed drop-shaped in a known manner and serve to accommodate cross-section matched tumblers 14.

  • the tip portions 17 of the core pins 15 are based on the opposite keyway broadside.
  • the core pins 15 are dimensioned in their length so that then the housing pins 16 dive with a portion of their length in the core holes 12 and thus represent a rotation lock for the cylinder core 7. This means that the parting plane between the core pins 15 and the housing pins 16 lies inside the cylinder core 7.
  • Each tip section 17 is formed by mutual flattening of the core pin 15 in the tip region. The flats are placed so that they form ramps 18 which cooperate with counter-bevels 19 of the flat key 3.
  • the flat key 3 is composed of a key handle 20 and the outgoing therefrom key shank 21.
  • a reversible key which is inserted in 180 ° -Wende einen in the keyway 11.
  • the turning axis of the key 3 is designated A.
  • From each broad side of the key shank 21 is ever a Tiefrippe 22 and a high rib 23 each.
  • the deep rib 22 of a wide side is a high rib 23 of the other broadside opposite.
  • the recesses 24 may have a maximum depth predetermined by the locking system, so that the base 24 'extends within the deep rib 22.
  • the high rib 23 is key tip side associated with a groove 25. Their bottom forms the counter-slope 19. In this way, a gate is formed, which must pass through the tip portions 17 of the core pins 15 in the key insertion.
  • FIGS. 3 to 5 Flat key 3 illustrated in the insertion position thereof, the tumbler pins 14 are aligned so that then the rotational displacement of the cylinder core 7 is possible.

  • This means that the associated lock cylinder according to Fig. 10 four appropriately designed core pins 15 used as a marker pins, while after Fig. 11 the associated lock cylinder 2 must have two catch core pins 15. It is therefore possible to form the depth rib 22 with changing step 26.
  • the key 3 after Fig. 15 is a so-called two-step flat key. Both the lower rib 22 and the high rib 23 are sold in two stages. Accordingly, a step 26 and an upstream step 26 'are formed on the tie rib 22. On the same cross-sectional plane, the raised rib forms steps 35, 35 ', wherein the step 35' is close to the key tip and is provided at the height of the largest projection of the raised rib 23. There, the step 35 'represents the connection between the largest and the middle projection of the raised rib 23 over the relevant key broadside.
