  • Locking mechanism can be in an additional mechanical Pin tumblers for blocking the core Lock cylinder can be arranged.
  • the impulse is mostly generated by freely programmable control electronics.
  • the control electronics can, for example, by one in a key that moves the pin tumblers Activate code transmitter.
  • An access control system is known from EP 0 600 194 B1 known in which an electromagnetically activated Locking mechanism with a mechanically lockable locking cylinder forms a structural unit.
  • an electromagnetically activated Locking mechanism with a mechanically lockable locking cylinder forms a structural unit.
  • a control center controls the electromagnet depending on the data read out. For The lowest possible cabling effort is required that the electromagnet is on a data bus from the control center or with a battery can supply electrical current.
  • a locking cylinder is known from EP 0 526 904, where a coil of the electromagnet is below Pin tumblers is arranged.
  • the electromagnet is a coil core parallel to a closing channel slidably arranged for a core having a key.
  • the coil core can be removed from one of the end faces move the anchor plate arranged on the coil and penetrates in the open position in a notch of the vertical to the core locking bolt.
  • a disadvantage of this lock cylinder is the large number of to be assembled Components and quite a high power consumption when moving the anchor plate through the electromagnet.
  • the invention is based on the problem of a locking mechanism of the type mentioned at the outset is as simple and space-saving as possible and one has particularly low power consumption.
  • the locking mechanism according to the invention a particularly low Power consumption.

  • the locking mechanism according to the invention is designed particularly space-saving and is therefore particularly suitable for installation in a lock cylinder of a mortise lock.
  • the lock cylinder can be next to the locking mechanism according to the invention mechanical locking means exhibit.
  • Locking mechanism helps when in a Basic position of the anchor from the core against the pole face is biased. This design makes it unnecessary Energy consumption avoided by the anchor from the electromagnet only needs to be held.
  • the basic position is, for example, in the lock cylinder locking mechanism used the position in which the key can be removed from the locking channel. If the locking mechanism is not released the electromagnet has no electrical impulse, so that the Locking bolt when the core is turned into the locking recess penetrates and prevents further rotation. At a The electromagnet must release the locking mechanism Hold the anchor against the pole face so that the core can be moved without obstruction by the locking bolt. Since this does not cause the electromagnet to move the armature, but only has to hold, he needs particularly little Forces and thus a very low energy requirement.
  • the anchor is disc-shaped and the locking bolt pin-shaped.
  • a compensation of an angular deviation between the electromagnet and a guide for the locking bolt is designed according to an advantageous Further development of the invention is particularly constructive easy when the locking bolt can be pivoted relative to the anchor is. Furthermore, this design leads to a particularly simple assembly of the electromagnet, since this fixed in a holder without complex alignment can be.
  • the pre-assembled structural unit consisting of a locking bolt and Anker is structurally particularly simple if the locking bolt penetrates the anchor in a recess Has spigot and if the free end of the spigot has a widening for reaching behind the anchor. This ensures that the amount to opposite the locking bolt in its direction of movement the anchor is slidable, the intended for Function of the locking mechanism does not exceed the necessary dimension.
  • Annoying noises of the locking mechanism according to the invention can be easily avoided by using the locking bolt a retaining spring is clamped away from the anchor.
  • Locking mechanism helps if the Electromagnet a pot magnet with a flat pole face for the installation of the also just designed anchor.
  • the electromagnet has another advantageous one Development of the invention very high holding forces in particular small dimensions when the pot magnet is one of a coil surrounded inner housing part and a Has spool surrounding outer housing part.
  • the outer housing part at the same time as a component of the housing shielding the electromagnet become.

  • the housing for shielding the pole face and the armature requires according to another advantageous training the invention requires particularly little construction, when the anchor, the lid and adjacent to the lid Areas of the electromagnet made of the same material are.
  • a line of strong, outside of the invention Locking mechanism arranged magnetic fields to the armature can be easily avoided if the locking bolt and the Lock spring made of a non-magnetic material are.
  • the locking mechanism is easy to prevent when the locking bolt is in the open position during a rotation of the core slightly against the force of the retaining spring is movable.
  • the locking bolt can, for example protrude slightly into the path of movement of the core.
  • the locking bolt is also with armature resting on the pole face with every revolution of the core moved slightly and thus sticking or rust film solved.
  • the core could be a single wedge-shaped Locking recess for receiving the locking bolt in the locked position have, so that it is in the locked position only in one Direction can be moved.
  • the locking mechanism according to the invention only lock the fitted lock, but without impulse no longer unlock the electromagnet.
  • the lock bolt according to another advantageous development of the invention with each movement of the core moves several times if the core has two barrier troughs adjacent to a residual to penetrate the locking bolt. This will Rust or stick the locking bolt in the open position avoided particularly reliably.
  • the manufacture of the locking mechanism according to the invention is designed itself particularly easy when the electromagnet designed cylindrical and in a likewise cylindrical, recess tapering to the movable core is arranged.
  • the intended position of the locking bolt opposite the Electromagnets can be advantageous according to another Further development of the invention simply determine if the residual in a mounting position of the electromagnet is oriented towards the locking bolt. For assembly the core is simply moved into the assembly position. Subsequently can the electromagnet together with the Anchor, the locking bolt and the locking spring up to the stop, where the locking bolt from the residue against the Anchor plate and this is pressed against the pole face, insert into the recess and fasten.
  • the locking bolt penetrating into the locking trough can become cant in its guide without damaging its flanks be when the locking bolt is all-round, in one in the locked position between the recess and the Core located area arranged clamping groove. If the locking mechanism is attempted in the locked position, the Moving the core with great force initially prevents the Shear forces on the locking bolt and locking trough a rotation of the locking bolt. The same time as the radial attack Shear forces on the locking bolt and vertical acting Forces on the locking bolt try the locking bolt easy to tilt and against the force of the locking spring to push out of the recess.
  • the perpendicular to forces acting on the locking bolt are, for example due to asymmetries in the arrangement of locking bolts and Core or through the necessary play of the locking bolt in his leadership evoked. Thanks to the invention can the locking bolt no longer moves out of the locking recess, because the edge of the locking trough in this clamping groove engages and the locking bolt tilts slightly, so that an edge of the guide of the locking bolt also in the Engages clamping groove.
