Definitions

  • the invention relates to a double lock cylinder according to the preamble of claim 1.
  • Lock cylinders in which a lock is caused by the latching of an electromagnet, are known, for example, from DE-OS 35 01 345.
  • the electromagnet interacts with the cylinder core.
  • the invention is therefore based on the object of designing a double lock cylinder of the type mentioned in such a way that, on the one hand, opening from the outside can only take place with an authorized, that is to say correctly coded and mechanically matching, key, on the other hand opening of the lock with a mechanically matching key from inside is possible at any time.
  • the double lock cylinder has an inner cylinder 1 and an outer cylinder 2. Between the two is the lock bit 14, which is carried in a known manner by a claw when the cylinders 1 or 2 rotate and thus allows the lock to be actuated. 2, the claw 5 is shown partly in section, in which two half-shells are arranged. The lower half-shell 3 ⁇ is in engagement with the magnet armature 11 of an electromagnet 13 or can be brought into engagement therewith and has a corresponding recess for this purpose. This electromagnet is arranged in the cylinder housing 12. The upper half-shell 3 is also provided with a recess 18, in which case the coupling 15 indicated in FIG. 1 can intervene in order to take the half-shells with it To allow rotation of the outer cylinder.
  • a ball catch 6 is provided which, starting from the claw 5, is held in a corresponding recess in the lower half-shell 3 ⁇ in the illustration shown in FIG. 1 and thus also the upper half-shell 3 .
  • the coupling 15 in the longitudinal groove 20 of the claw 5 is shifted to the left in the retracted state of the magnet armature, that is to say in the de-energized state, from the inside using a key 16 (FIG. 3)
  • the recess 19 of the coupling 15 releases the half-shells .
  • the key 16 can be turned and the lock can be opened with the claw. It is different when a key 17 is inserted into the outer cylinder 2.
  • a reading coil 7 is arranged, which can read codes on a key in a known manner.
  • This reading coil 7 is connected to the electromagnet in accordance with the control system via corresponding lines 8, the control system being connected via the plug 9 in FIG. 2. If a key 17 equipped with a coding is now inserted from the outside, that is to say into the outer cylinder 2, the coupling is shifted to the right (FIG. 4), and the half-shells locked by the magnetic armature prevent the key from rotating. Now the lock electronics (which is not shown in detail) checks the authorization of the key, and the circuit is if the authorization is given, released.
  • the electromagnet which holds the magnet armature in engagement with the lower half-shell when the circuit is closed, is de-energized, the lower half-shell is released and thus these half-shells can be turned around the claw and the lock can thus be actuated.
  • a suitable mechanical key for example, is inserted into the outer cylinder 2, but does not have a corresponding coding to be recognized by the reading coil 7, the lock electronics will not release the circuit and therefore no locking operation can be carried out.
  • the lock is thus mechanically and electronically secured from the outside, while from the inside with a suitable mechanical key, regardless of its coding - e.g. also with a hazard key - the lock can be opened.
  • the electromagnet 13 is also in the profile cylinder.
  • the half-shells 3 and 3 ⁇ are also shown.
  • the mobility of the half-shells 3 and 3 ⁇ , in particular the half-shell 3 ⁇ in the recess of the claw, which is only indicated, is restricted by the locking pin 30, which, as can be seen from the figure, is conical at its upper end 37 and with corresponding conical stop surfaces 38 is engaged on the half-shell 3 ⁇ .
  • This locking pin 30 has a shoulder with a circumferential groove 31, and with this circumferential groove a plurality of balls 32, and preferably four balls, are engaged, which in FIG Housing bores 16 are radially movable. This radial mobility of the balls 32 is achieved in that the locking pin is axially displaceably mounted.
  • the locking pin 30 is surrounded by a pot-like sleeve 33 which has an extension 34 which forms the actual magnet armature, ie can interact with the electromagnet 13.
  • the magnet armature can be drawn into the magnet, that is to say axially movable, against the force of a spring 35 which pressurizes the lower part of the magnet armature.
  • the sleeve 33 has an inner groove which corresponds in its configuration to the circumferential groove 31 on the locking pin 30.
  • the balls 32 can perform the greatest radial movement when the locking pin and sleeve 33 are in one position, as shown in the drawing.
  • the locking pin 30 can be moved axially downward, namely by turning the half-shell 3 ⁇ , in which case the balls 32 dodge radially. This is the de-energized state or the balanced state of the electronic key.
  • the electromagnet is triggered and the magnet armature 34 is drawn into the electromagnet 13 and in this way moves the sleeve 33 in such a way that the inner groove engages the sleeve is no longer aligned with the housing bore 36 for the balls.
  • the reading head 7 is glued into a recess in the cylindrical part of the housing, in such a way that it is flush with the outer circumference.
  • This recess is located in the upper apex area of the housing and is thus arranged directly adjacent to the inserted key, which has the usual counter coil in its back.
  • the connection wiring 8 for the reading head which leads to the system electronics (not shown), is in a corresponding groove 21 which extends along the housing to a point at which the connection plugs protrude beyond the outer circumference of the housing. It is expedient and particularly advantageous if the wiring is in the form of conductor tracks. Furthermore, it is provided that the groove 21 is filled with a conductive potting compound after the wiring or the conductor track has been inserted, and is thus also flush with the outer circumference of the housing.
