Definitions

  • the invention relates to a cylinder lock with a cylinder core, a key can be inserted into its key channel, through which a slide element is displaceable in the cylinder core and, the position of the slide element (11) being scanned by a locking bar, optionally with a locking element in a locking recess engages the cylinder housing and blocks the lock or can be disengaged from the recess and the lock releases.
  • the object of the present invention is inter alia based on a mechanical overload protection for the query slide elements or locking pins, etc., that meets the requirements outlined above, if possible is cheap to manufacture and wear-resistant, as well can be easily assembled.
  • the cylinder lock mentioned above is according to the present Invention characterized in that the locking bar at least comprises a control slide and a query slide, which can be moved relative to each other against spring force are that the spool has at least one ramp surface possesses that when turning on one of the control edges of the Lockout opens and the locking bar in the cylinder core presses, and that the query slider is a query element for querying the sliding position of the slide element has, wherein in the blocking position of the slide element the radial immersion of the query slider prevents and further rotation of the cylinder core is blocked.
  • FIG. 1 shows a cross section by the cylinder lock according to the invention along the line I-I in Fig. 3.
  • Fig. 2 shows a partial section along the line II-II in Fig. 3.
  • Fig. 3 is a partially sectioned Side view of the cylinder core and
  • Fig. 4 is a partial cut supervision.
  • Figures 5, 6, 7 and 8 show sections analogous to Figures 1,2 at different Functional positions.
  • the cylinder lock has in a known manner a cylinder housing 1, in the core bore 2 of the cylinder core 3 is rotatable.
  • the rotation takes place around the Axis of rotation 4, through which the central longitudinal plane 5 of the cylinder core runs. If in the description of axial direction is spoken, it means a direction in or parallel to the axis of rotation 4.
  • the key 7 is received in the axial key channel 6, a control recess on each of its two flat sides 8 9 wears.
  • the other parts of the lock are by the control recesses 9 of the key are controlled, only drawn on one side of the central longitudinal plane 5. All of these parts can also be on the other side of the median longitudinal plane 5, or on both sides, that is, double.
  • the control recess 9 of the key controls one Querierbolzen 10, the slide element 11, which is in the slide recess 12 approximately parallel to the key channel 6 within of the cylinder core 3 is displaceable.
  • the slide element 11 in turn has two control recesses 13, 14 on, the one control recess 13 the query element 15 is opposite a radial locking bar 16.
  • the radial one Lock bar includes at least two solid bodies, namely the query slide 17 and one or more control slides 18.
  • the radial locking bar 16 is in an axial Recess 19 of the cylinder core 3 arranged and inside this axial recess in the radial direction.
  • the query slider 17 carries in towards the or the slide element (s) the query element 15, wherein it is preferably a bar.
  • the interrogation slide 17 carries a locking head 20, which in 1 in the recess 21 of the Cylinder housing 1 protrudes.
  • the radial locking bar 16 is biased to the outside by the compression spring 22, preferably several such compression springs are provided.
  • the compression spring 22 is on the inner wall of the recess 19 supported in the cylinder core, as can be seen in FIG. 1 is.
  • the spool 18 is part of the radial locking bar 16 together with the query slider 17 within the axial Recess 19 is displaceable and the control slide is also 18 against the query slider 17 against the force of Control spring 23 slidable.
  • the movability within the axial recess 19 corresponds to the distance 25, the at least the depth of the boundary 26 of the recess 21 should correspond. In any case, the route 25 as far as the immersion of the radial locking bar 16 allow that these are fully inserted into the cylinder core can be.
  • the control springs 23 together have a higher one Spring force as the commonality of all compression springs 22.
  • the control slide 18 has two control edges 27, 28, with inclined run-up surfaces 29 of the control slide 18th interact. As can be seen from FIG. 1, the Ramp surfaces 29 laterally to stop surfaces 30 of the locking head 20 arranged and the function is explained below.
  • the cylinder core 3 a series of four parallel to the key channel Slider recesses 12, each having a slider element Record 11.
  • the query bolts 10 are dashed indicated by a curved control groove 31 of the Key 7 brought into the appropriate sliding position are.
  • the radial locking bar 16 extends over all four slide recesses 12 and their slide elements 11.
  • the query slider 17 is provided as a bar and carries a strip-shaped locking head 20.
  • the compression springs 22 sit at both ends of the strip-shaped query slider 17th
  • the cylinder core In the functional position according to Figures 1 and 2 the cylinder core is in the 0 position, i.e. in the untwisted position Position as when inserting the key is given in the key channel.
  • the key is one correct key so that the cylinder core can be turned can.
  • Figures 5 and 6 show the situation when twisting the right key and how the locking head 20 under the Control edge 27 dips so that the cylinder core rotates freely can be.
  • Figures 7 and 8 show the functional position when a wrong key is inserted, in which the slide elements or one of the slide elements in the locked position stand.
  • the query element 15 cannot enter one of the control recesses Immerse 13, 14, which also causes the query slider 17 is prevented from moving under the control edge 27 of the recess 21 to dive through.
  • the locking head 20 strikes with its stop surface 30 at the limit 26 the locking recess 21 and the relatively high rotational forces are from the entire material thickness of the locking head 20th collected.
  • control slide 18 when initially rotating the cylinder core according to its Ramp surface 29, which runs on the control edge 27, pushed into the associated recess 19 in the cylinder core. This shift takes place against the force of the strong control spring 23 so that there is a relative displacement comes between control spool and query spool.
  • the query of the Control information of the key by slide elements can also be done differently, e.g. by tilting the Slider elements and key scanning in the side area. It is essential that the slide elements in one Direction are shifted by the key and their Sliding position is queried by a locking bar, the Movement is transverse to the first direction.
  • the number the slide elements can be selected as required. All locking elements can either on one of the castle sides or be provided on both sides.
  • the query sliders can be designed as a continuous bar, as here shown, or as individual sliders together be provided with a control spool each.
  • the springs 22, 23 can be replaced by elastic elements become.
  • the query element 15 by obliquely arranging the side surfaces in Cross-section be wedge-shaped, so that with analog wedge-shaped design of the recesses 13, 14 the locking bar can be pushed outwards when twisted.
