Definitions

  • the invention relates to an electrical or electronic Lock, especially cylinder lock, with at least one a coil containing generator for generating electrical Energy using one to be inserted into the lock Key and with an electromagnetic locking member with a locking bolt.
  • Electric or electronic locks can in principle be used can be supplied with energy in any way. Besides the possibility a mains connection or a backup battery proposals have already become known for which the required Energy when inserting a key under Mediation of the key is generated. In this way can avoid additional electrical installations to ensure the energy supply.
  • DE-OS 3 819 954 describes, for example, a locking device with an address memory. It is about a system that can be used as an access control system a comparison of a key code with one in code stored in a lock memory.
  • the Key coding here has an address code, the at least one byte of memory is allocated. This byte can assume two states. The key is in a reader inserted, the corresponding address is called and read the byte. Assumes the first state the key is granted access, in the second the Access blocked. Locking authorization for a key to give, a programming card is required here, which before inserted the key to be programmed into the reading slot must become.
  • DE-OS 4 201 936 describes a magnetic card lock. To the To open the lock, the magnetic card must be placed in a slide be inserted and move it against a spring for so long until the locking mechanism is actuated. Since the Slide by tumblers, consisting of permanent magnets, which are connected to a housing by means of springs, in its Position is held, these tumblers must first be pushed back. This is done by pushing it in the magnetic card with the same permanent magnets how the tumblers must be equipped, the being effective magnetic repulsive forces between the card and the tumbler unlocking causes. If the card comes out of the Slider is removed, due to the spring, the closed position accepted again.
  • EP-A1-462 316 already includes a locking cylinder an electrical locking device has become known, which was designed as a double lock cylinder and on one Side carries a rotary knob.
  • this known double lock cylinder was turned by turning the rotary knob generates electrical energy, which is then used to unlock an electromagnetically actuated locking pin was able to deliver the required energy.
  • the locking pin in a way to arrange that a predetermined rotation of the key without Blockage by the electromagnetically actuated locking pin was made possible, and in this way it became a partial route of the Rotary movement of a key used to generate energy.
  • an electromagnetically unlockable one Lock pin absorb relatively high mechanical forces, and it relatively much electrical energy is required in order to do so stable locking pins securely from a locking position into one To move the unlocking position.
  • the space available comparatively low is the space available comparatively low.
  • the present invention therefore aims to provide an electrical or electronic lock of the type mentioned to continue training, with the smallest possible dimensions to achieve a secure locking or unlocking, while at the same time for such a secure locking or unlocking required energy in a simple manner directly in the castle should be able to be generated.
  • the training according to the invention essentially in that the locking member by a magnetic shunt to the one carrying the coil (s) Generator can be operated, the key several Carries permanent magnets, one with one to the the other permanent magnets arranged on the key inverse Polarity is formed, or a soft part is arranged in the key which is with at least one additional permanent magnet cooperates in the cylinder.
  • Electrical energy is generated by the invention Training the same coils which the Serve energy generation, also for the generation of electromagnetic Field, which is the displacement force generated for the locking bolt or locking pin.
  • the Dual use of the coils of the generator for the magnetic Unlocking allows it, even with very little space a safe and mechanically sufficiently stable construction to accomplish.
  • the training for this is particularly advantageous hit that the locking bolt in a metallic, magnetically conductive guide part is guided, which with a yoke part carrying a generator coil can be magnetically connected via soft magnetic yoke parts is.
  • a training one becomes special compact construction ensures that the Locking bolt leading part with a generator coil supporting yoke in a particularly simple manner by elements of Key itself is magnetically connectable.
  • the training is advantageously made so that the magnetic Connection of the locking bolt leading Guide part with the yoke part carrying a generator coil by bridging a gap by inserting a magnetic or soft iron containing part of the Key can be produced.
  • a linear generator Is used in which one in the axial direction Key a plurality of magnetic sections or Sub-areas containing soft iron in operative connection with a yoke passing through the generator coils can naturally by using magnetic sub-areas in the key that penetrating the generator coils Yoke parts made of soft iron.
  • the training so made be that of key or soft iron Portions of the key penetrated each gap is limited by pole pieces.
  • the magnetic Flow over the yoke that guides the locking bolt can, so here either when using soft iron Sub-areas of the key the direction of magnetization must be reversed to flow over the locking bolt to force.
  • the foremost portion of the key is soft magnetic be, whereas all the rest of the generation of electrical Energy-effective sub-areas of magnets can be formed, which in a preceding gap between the ends of one formed by soft iron parts Yokes induce magnetic field lines.
  • the training preferably made such that the guide part leading the locking bolt in one in Direction of insertion following level with interposition a gap on the yoke parts carrying the generator coils connects and with insertion of magnetic or soft iron sections of the key magnetically with at least the coil-bearing yoke parts can be connected.
  • the desired magnetic flux to unlock the locking bolt is advantageously achieved in that two sections of the key seen magnetically in the axial direction different direction of magnetization or as soft iron sections are formed and at a distance from each other are arranged, in which these are fully inserted Align keys with the soft magnetic yoke parts, due to using the mechanisms discussed above either a piece of soft iron or using one magnetic range with reverse polarity according to the invention the guide part leading the locking bolt fully inserted key can be coupled with the generator coils is.
  • FIG. 1 shows a side view of a key for use in an electrical according to the invention or electronic lock
  • 2 shows a schematic section by an electric or electronic lock according to the present invention with key inserted
  • Fig. 3 partially in an enlarged and perspective view electrical or electronic lock according to the invention.
  • the two coils 8 are not only be used for energy generation, but also for Actuation of the locking bolt 10 serve.
  • the locking bolt 10 supporting guide part 13 is here arranged between the yoke parts 6 and 7, so that overall results in a very compact embodiment.
  • Using of only one generator coil 8 must be special for one accurate guidance of the locking bolt 10 taken care of be while using two generator coils 8 an asymmetrical due to the symmetrical arrangement of the yoke parts The introduction of forces is largely eliminated becomes.
