Definitions

  • the invention relates to a lock cylinder with a built-in electromechanical lock, which comprises an electromagnet with magnetic coil and iron core that can be controlled by an electronic comparison circuit, in a bore in the cylinder housing, the bore being extended into a cylinder core and having a tumbler with a core and housing pin, and in particular is located in a series of mechanical tumblers, which can be moved from a locking position into a release position by means of a key in a bore in the cylinder housing, which are continued in the cylinder core rotatably mounted in the housing, and a housing pin in the bore from Iron core is displaceable when the magnet coil is excited, and a core pin which can be displaced from the locking pin into the key channel from the locking pin is mounted in the bore at the end of the housing pin facing away from the iron core.
  • Lock systems which operate on the basis of a cylinder lock with a flat key.
  • the key bit moves a number of spring-loaded core and housing pins in the locking cylinder.
  • division - i.e. the contact surfaces of the core pins with the housing pins lie in the cylindrical surface of the core - then the core can be rotated in the housing and the locking mechanism is open.
  • a known exemplary embodiment provides, for example, a code transmitter in the key box, which is inductively supplied with energy in the vicinity of the lock and emits its code.
  • magnetic or mechanical code elements on the key are also known, which can be scanned electrically or optically.
  • a receiver is provided in the rosette of the cylinder, which receives the incoming code and then compares it with a stored lock code. If the code matches, an additional lock is unlocked in the lock cylinder or in the mortise lock.
  • Such a system therefore presupposes that both the mechanical key secret transmitted via the toothing of the flat key as well as the electronic key secret realized by the code in the lock is recognized and matches, so that locking takes place.
  • the particular advantage of such a lock system lies in the simple possibility of reprogramming, for example if a key is lost or if the access authorization is changed.
  • the electronic circuit additionally requires a lock, which is switched on or off in accordance with the result of the electrical target / actual comparison.
  • an electromagnet is known from EP-A3 281 507, the magnet armature of which engages in a half-shell of the coupling. If an additional coded key is inserted on the outside, the coupling is unlocked electromechanically, provided that the additional coding is correct in addition to the mechanical lock secret. From the inside, a key with a mechanical lock secret is sufficient for the locking process.
  • US Pat. No. 4,798,068 shows a balance beam or a rocker with two pins, one of which engages in a bore in the core and the other in the key channel. A spring causes the latter pin to be pressed into the key channel.
  • the rocker is switched by an active key, whereby the signal of a key-side signal generator in the lock is evaluated and, if the code matches, a switching magnet is activated electrically.
  • an electromagnetic lock lock which comprises a solenoid which inserts one or more pins into a blind bore of the cylinder core or displaces these or other locking elements and locks and unlocks the cylinder core. Regardless of this, a flat key is provided, which brings core and housing pins to division in a known manner. The design requirements are low energy consumption and minimal size. Furthermore, the electromechanical lock should lock the cylinder core in the de-energized state and released in the energized state.
  • a stamp is pushed axially from a magnetic coil to a telescopic assembly which, when the electromagnet is excited, is pressed into the core against a control surface of a key is, the release position is reached at full stroke of the solenoid.
  • the contact surface of the telescopic assembly which corresponds to a core pin in a locking cylinder, with the stamp of the magnetic coil lies exactly in the lateral surface of the cylinder core of the locking cylinder, so that the cylinder core can be rotated in a cylinder housing.
  • the invention aims to remedy this disadvantage and creates a prerequisite that the interlocking interacting with the electronic circuit and controlled by it can be built directly into standard components with the least possible effort and an electronic criterion is superimposed on a mechanical key secret with all the properties of known pin tumblers .
  • the housing pin can be displaced into the bore of the cylinder core by the electromagnet.
  • the magnetic coil with its iron core replaces the spring of a common tumbler in the locking cylinder, which pushes the housing pin and the core pin into the key channel of the cylinder core until the core pin is in contact with the key notch. If the appropriate key is inserted, it moves the usual core and housing pins against spring force into the dividing surface or forms the stop of the last-mentioned pair of pins, so that division occurs.
  • the locking cylinder can be locked. But if the key notch of a wrong key is too deep, the housing pin moves into the cylinder core and blocks the lock, even if the electronic code was correct. If the code is read from mechanical or electronic brands of the key bit or the back of the key, it is only fully recognized when the key is fully inserted into the key channel.
  • the core pin and housing pin act directly against the stop of the key bit toothing in the key channel located key.
  • the stop position reached is immediately the division position in which the contact surface between the core and housing pins lies exactly in the outer surface of the cylinder core. Due to the variation of the key toothing, the end stop of the core pin and thus its length matched to the key represent an important safety criterion.
  • the solenoid remains unexcited and the core and housing pair remain in a position that cannot be reached by the key, in which the core pin lies exactly in the cylindrical surface of the core and a rotation of the core prevented.
  • the core pin lies exactly in the cylindrical surface of the core and a rotation of the core prevented.
  • a brake in particular a friction brake, which engages the core or housing pin or the iron core is provided, which after short-term excitation of the magnetic coil when the key in the key channel reaches the insertion position, at least the core pin in the advanced position holds in the core and when the core and possibly the housing pin and possibly the iron core can be reset by a prong of the key bit profile that comes into contact with the core pin.
  • the magnet coil carries the friction brake for the housing pin or its extension or intermediate piece at its end facing the housing pin, which is designed as a sleeve or magnet coil with a friction-locking collar and which the housing and when the solenoid is switched off holds the core pin in the extended position while compensating for its own weight.
  • a braking effect can also be achieved by a permanent magnet against the iron core or a ball catch.
  • FIG. 1 shows a flat key for a locking cylinder
  • Fig. 2 shows a longitudinal section through half of a locking cylinder and a rosette
  • Fig. 3 shows a front view of the locking cylinder according to Fig. 2
  • Fig. 4 shows a detail from Fig. 2 with excited 5 shows a detail from FIG. 2 on an enlarged scale
  • FIG. 6 shows a friction brake.
  • a flat key 1 (FIG. 1) has a key profile 2 and a toothing 3 which, when inserted into a key flap 4 of a locking cylinder 5 (FIG. 2), displaces spring-loaded core pins 6 and housing pins 7 such that their contact surfaces 8 in the cylinder surface 9 of the cylinder core 10 comes to rest, so that the cylinder core 10 can be rotated in the housing 11 of the locking cylinder 1. While, for example, five rows of the above-mentioned core and housing pin pairs acting as tumblers are provided in the conventional mechanical locking cylinders, which are in bores 12 by springs 13 in Biased towards the key channel 4, the locking cylinder 5 shown in Fig.
  • FIG. 2 has four tumbler rows with springs and a fifth hole in which a core pin 14 and a housing pin 15 are provided, which are not mechanically sprung but by a magnetic coil 16 can be moved against the key channel by d it is made of brass or another working pin 15 indifferent to magnetic forces with an extension 17 into the interior of the solenoid 16 designed as a solenoid.
  • An iron core 18 is in the de-energized state of the solenoid 16 (FIG. 2 and 5) largely outside of the solenoid and is drawn into the interior when voltage is applied to the connections 19 and thus when the latter are excited. The iron core thus lifts the housing pin 15 and the core pin 14 and pushes them in the direction of the key channel 4 (FIG. 4).
  • the four mechanically sprung pin pairs (6, 7) of the first four tumblers are brought to division against the forces of the mechanical springs 13, while the pair of pins 14, 15 reach division against electromagnetic forces.
  • the lock cylinder can then be operated.
  • the effect on the pins 14, 15 is similar to the effect of the spring 13, but the electromagnetic spring effect can be switched on or off by energizing or de-energizing the solenoid.
  • the solenoid is switched off the pins 14, 15 fall down (FIG. 2), the core pin 14 lying in the transition region from the core 10 and the housing 11 and blocking the actuation of the locking cylinder 5, even if the first four tumbler pairs are brought to division.
  • the key 1 has a further coding, in the example a small code transmitter 20 in the key box, the signals of which are received by a receiver 21 in a lock rosette 22 and compared with a target code. If the code matches - that is, if the key 1 was recognized as being authorized to lock - the solenoid 16 is connected to voltage via a line 23. The key then locks the cylinder like a classic mechanical locking cylinder. If a code match cannot be determined in the receiver 21, the solenoid remains unexcited and the pins 14, 15 in the locked position outside the key channel. Key 1 brings the first four tumblers to division, but the fifth tumbler (pins 14, 15) remain passively in the locked position. You are not reached by the key. The locking cylinder remains locked.
  • the excitation can be switched off again immediately after the build-up of the electromagnetic field if a friction brake acts on the housing pin 15 or its extension 17, which prevents the raised housing pin 15 from falling back.
  • the excitation occurs in particular only when the key 1 is fully inserted into the key channel, so that the core pin 14, which shoots up due to magnetic forces, and the housing pin come to rest directly in the dividing surface by the correct key. It can therefore be blocked.
  • the front tooth 24 of the key toothing pushes the pair of pins back into a neutral position which does not correspond to the division position.
  • a cuff 25 can be provided as a friction brake according to FIG. 6 be, which is fixed on the magnetic coil 16 and has an annular collar 26 which abuts the extension 17.
  • the dashed arrow shows where the cuff can be installed in a fixed position.
  • permanent magnets 27, 28 are also shown, which hold the pulled-up iron core 18 in the upper position against the dead weight and the weight of the housing pin 15 and the core pin 14 after pulse activation and switching off of the excitation. Only when the key 1 is withdrawn does the prong 24 (see dashed line in the key channel 4 in FIG. 2) press the core and housing pin down from the dividing surface and thus the iron core from the area of action of the magnets 27, 28. The iron core 18 and not magnetic pins (17, 15, 14) thus fall into the position according to FIG. 5 and wait for the next excitation of the magnetic coil via the connections 19.
