Definitions

  • the invention relates to a cylinder lock, in particular for receiving in a door, with a protection against manipulation by impact, according to the preamble of claim 1.
  • Cylinder locks for locking doors or other relatively movable parts are well known in the prior art and have a housing and a rotatable in a receiving bore of the housing by means of a key core, via an array of core-side and spring-loaded housing side, slidably in holes recorded locking pins can be locked and unlocked.
  • the core pins are radially displaced according to the configuration of the key bit in such a way that the substantially cylindrically shaped core can be rotated when the contact surfaces of the associated pairs of core and housing pins with the cylinder jacket Peripheral surface of the core are aligned.
  • the aforementioned Zyliriderschlösser be referred to here as an oval cylinder, round cylinder or profile cylinder.
  • a cylinder lock in which a protection against unlocking of the lock by means of the impact technique described above is obtained in that at least one of the housing pins has a first and second pin part, which are coupled together with radial play and in which between the first pin part and the second pin part a helical compression spring acts which biases the second pin member toward the core with a resilient force.
  • the second pin part tilts laterally and prevents further rotation of the core relative to the housing.
  • a cylinder lock has a housing in which preferably at least two, but preferably more than two, spaced apart first housing-side bores are formed along a row or two rows, which communicate with an axial receiving bore in which a substantially cylindrical or at least partially cylindrical core is rotatably received.
  • each of the first housing-side bores preferably a single housing pin is slidably received along the bore, which by resilient Is urged means in the form of a coil spring in the direction of the axial receiving bore.
  • second core-side bores are introduced in the region of the cylinder jacket-shaped peripheral portion, which in the inserted state of the core are aligned with the first housing-side bores.
  • core pins are slidably received, each of which is aligned in a predetermined rotational position (normal position) of the core with the associated housing pin and by inserting a legitimate key with a corresponding to the closure of the lock designed beard or Bohrmuldenan extract in the manner in the second core-side bore is moved so that the front end surfaces of all core pins and the front ends of the adjoining housing pins in the region of the parting line of the castle, which extends between the inner wall of the axial receiving bore and the cylinder jacket-shaped peripheral portion of the core.
  • a recess or recess is introduced in the region of at least one of the core-side second bores, the edge of which defines a stop surface or stop edge extending from the bottom or bottom of the recess to the outer surface or to the parting plane for the associated housing pin when the core is rotated using a manipulated key after impact in the up and / or locking direction of the lock.
  • the housing pin associated with the recess is moved into the recess beyond its parting line after its movement despite a torque acting on the core on its return movement caused by the acting spring forces and strikes there in a further rotation the core with its peripheral surface on the stop surface or stop edge, which is preferred here extends coaxially to the axis of rotation of the core, and may have a straight or arcuate shape with a curvature, which preferably corresponds to the curvature of the associated housing pin.
  • the cylinder lock according to the invention has the advantage that by simply introducing a depression even in existing cylinder locks - no matter whether Ovalzylinderschlösser, Rundzylinderschlösser or widespread in Germany profile cylinder locks - with relatively little effort a highly effective protection against opening of the lock by means of the impact technique described above is obtained without disproportionately increasing the production costs for the locks.
  • the stop surface for the associated housing pin extends - relative to the axis of rotation of the core in the axial receiving bore - in a substantially radial direction, so that the stop surface with a running at the intersection of abutment surface and cylindrical peripheral portion Tangente a preferably includes right angle, so that the stop surface extends at least in a partial section parallel to the outer surface of the housing pin.
  • the stress exerted on the pin notch effect is in a locked core compared with a also conceivable and included by the invention narrower edge-like contact surface or stop edge, which results when the abutment surface relative to the peripheral surface in the circumferential direction is inclined at an acute angle, advantageously reduced,
  • the stop surface preferably has a height of at least 1 mm, but preferably of 2-3 mm. This ensures that the housing pins always engage reliably in the recess even with intensive use of the striking technique using repeated blows and do not jump over the stop surface, whereby the security of the castle is further improved even further.
  • the recess - which preferably as a cutout by means of a sectionefräsers, which is guided at a substantially constant distance from the axis of rotation of the core along a circular arc over the cylinder jacket-shaped peripheral portion of the core - a constant depth, which in Trap of a right angle between the preferably defined by the side wall of the recess stop surface and the bottom of the recess in the aforementioned range of 2-3 mm, although the depth can be selected larger or smaller.
  • the wall thickness of the usually used in the known cylinder locks ring or sleeve-shaped outer body for the cores, in which the corresponding, with the second core-side bores and the closing channel for the keyed inner body are used may have a comparatively thin wall thickness.
  • the distance between the stop surface and the outside of the associated core pin in the circumferential direction of the core is preferably less than 80% of the diameter of the core pin, wherein the distance between the outside of the core pin and the stop surface preferably between 40% and 60%, and more preferably in the range of 50% of the diameter of the core pin.
  • the recess preferably symmetrically on both sides of the bore over this away, so that through the wall or edge surface of the recess on the side opposite the abutment surface of the core pin preferably a mirror image another Stop surface is defined, which serves as a stop for the associated housing pin when the core is rotated in the opposite direction of rotation.
  • This refinement of the cylinder lock according to the invention affords the advantage that the cylinder lock can be used both in the case of right-hand and left-closing doors, without a distinction being made between left-hand or right-closing doors, in which the cylinder lock according to the invention is to be used, in terms of logistics got to.
  • the recess or recess is introduced only in the region of a single core pin in the cylinder jacket-shaped peripheral portion of the core - the recess preferably has a width which is slightly larger than the associated housing pin, so that this without jamming in the Groove is performed - there is also the possibility that the recess extends in the axial direction of the core over at least two adjacent core-side holes away.
  • a total of five core-side and five housing-side holes only at the first, the third and / or the fifth hole recess according to the invention is introduced, as described above using the example of a single hole.
  • an inventive cylinder lock 1 for receiving in a door, not shown, a housing 2, in which first housing-side bores 4a - 4d are formed, in which a corresponding number of housing pins 6a - 6d is slidably received.
  • the housing pins 6a-6d are urged by unspecified resilient means from the respective housing-side bore 4a - 4d out in the direction of communicating with the first housing-side bores axial receiving bore 8 for a cylindrical core 10, with the aid of a in a closing channel 12 of the core 10 insertable key 13 within the receiving bore 8 is rotatable.
  • one of the number of first housing-side bores 4a - 4d corresponding number of second core-side holes 14a-14d is formed, in each of which a corresponding number of core pins 16a-16d are also slidably received, with one end to the out of representation Reasons only partially indicated beard 18 of the key 13 abut, and in the rotational position of the key 13 shown in Fig. 1 when using a legitimate key with their second ends to the associated ends or end faces of the housing pins 6a - 6d abut, such that the adjacent end faces of the core and housing pins 6a - 6d, 16a -16d are located in the region of the parting line 20, which extends between the inner surface of the axial receiving bore 8 and the outer surface of the core 10.
  • the core 10 has at least one circumferential peripheral portion 22 which extends in the region of at least one of the core pins-in FIG. 1 the core pin 16a.
  • a recess or recess 24 is formed in the cylinder jacket-shaped peripheral section 22, which in the embodiment of the invention shown in FIGS. 1 and 2a-2c is located in the region of the second core-side bores 14b 14d and which forms an abutment surface or abutment edge 26a for the housing pin 6b-6d, if the lock 1 is not opened with an authorized key 13 in a known manner, as shown in FIG. 2b, but instead as shown in FIG. 2c with a manipulated key 13 'using the striking technique.
  • the associated housing pin 6 b - 6 d slides over the recess 24, for which purpose the recess 24 is designed in such a way that the distance 30 between the edge of the recess 24, or the stop surface 26a and the outer side of the core pin 16b -16d preferably corresponds approximately to half the diameter of the core pin.
  • the recess 24 extends beyond the second core-side bore 14b-14d in the circumferential direction and thereby forms a further stop surface 26b, which likewise serves as a stop surface 26a for the associated core pin 16b -16d is used when the core 10 is rotated using the striking technique opposite to the direction indicated by the arrow 28 first rotational direction, for example, to block the associated cylinder lock 1 unjustifiably.
