Definitions

  • the invention relates to a safe, in particular with several lockers, as he is described in the preamble of claim 1 and a method for monitoring the operating status of at least one locker.
  • Locker systems are therefore known in which one of the two locks in the door, namely the bank lock, via a remote control device by a bank official, who has his workplace outside the locker system are released can.
  • a lock is known for example from EP-OS 0 096 400.
  • Additional safety circuits ensure that in the event of an incorrect release the bank clerk automatically locks the bank quickly occurs again, so that a later attempt by a customer with a false key Breaking into a locker fails.
  • security measures such as motion detectors, infrared sensors and other, arranged, as is usual with other vault systems is.
  • From DE 32 21 623 A1 is a lock for lockers with an unlocking option for the customer via a key and with an additional electrical Bank release known.
  • This lock has one by the key of Locker customers can move the lock bolt.
  • the remote bank lock comprises a locking lever pivotable by an electromagnet, wherein depending on the pivot position of the locking lever of the lock bolt in its displacement movement is released or blocked by the key.
  • the Electromagnet has two coil windings, the first winding for Builds a magnetic field for pivoting the locking lever and in the further winding by the movement of the locking lever, a voltage pulse is induced as a display signal for a locking or opening process of the Locker is evaluated.
  • the one when locking the locker in the second Coil-induced electrical voltage also serves as a signal for switching off the current in the first coil, so that the locking lever in the locked position for the Lock bolt can fall back.
  • the disadvantage here is that the second coil only during a lock or unlock the locker a signal about the current Can give lock actuation to a control or display device. Furthermore it is disadvantageous that in this coil due to the movements of the locking lever induced tensions not least because of the one-time provision and problematic due to the low electrical power in the evaluation are.
  • DE 21 34 630 A1 which specifies the preamble of claim 1, also describes a lock for lockers, which one with a key lock to be operated and a lock bolt assigned to the lock bolt Has lock bolt lock to be actuated by an electromagnet.
  • the lock bolt lock is formed by a pivoted two-armed lever, one lever arm cooperating with the electromagnet and the other lever arm depending on the operating state of the electromagnet with one stop can be placed in or out of active connection.
  • the one to be controlled Pivoting the lock bolt lock provided electromagnet has an open Magnet yoke on, the lock bolt forms the armature of the electromagnet. If the lock bolt lock is inactive, i.e.
  • Electromagnet when activated Electromagnet, the lock bolt by turning the customer's key shifted, there is a change in the current consumption in the already activated or energized electromagnet. In particular, increases by distance of the lock bolt acting as an anchor from the current-applied electromagnet Current consumption too. This current increase of the current that was previously supplied with current for bank release Electromagnets when transferring the lock bolt into the Open position is an indication of the opening process currently taking place evaluated and visualized via a display device, in particular a control lamp. Similarly, during the closing movement of the lock bolt along of the open magnetic yoke of the electromagnet, whose current consumption is increasing less.
  • Electromagnet is used as a sign of something that is currently in the closing phase Locker rated and displayed accordingly and for switching off the Electromagnet power supply used. This will make the electromagnet deactivated and the lock bolt lock reactivated.
  • the disadvantage is that the with the movement of the lock bolt during the closing or opening process associated change in the current consumption of the electromagnet is only an indication for just activated locks and a query of the respective operating states any locker locks are not possible.
  • DE 32 24 753 A1 is a security lock, in particular a lock for one Locker with a lock bolt that can be operated via a customer key and with an electromagnetically adjustable locking lever assigned to this lock bolt described.
  • An opening movement of the lock bolt is only at additional activation of the electromagnet and resulting Swiveling of the locking lever possible.
  • To record the opening or The locked state of the lock is the end area facing away from the lock housing of the lock bolt a contact element, e.g. in the form of a contact switch, or a non-contact sensor assigned.

Furthermore, an independent sensor device is in Form of an inductive coil provided for detecting the door position and with the electrical control device connected.
  • the disadvantage here is that the independent, non-contact sensor arrangement for detecting the door position in addition to the electrical locking or release elements is arranged and thereby additional Installation effort entails and requires a certain amount of space.
  • EP 0 316 691 A1 describes a device for monitoring the closed state a closing member that can be moved back and forth between an open and a closed position is revealed.

  • FR 2 534 392 A1 describes a locking system which has a main and has a locking bolt assigned to it. Both the main and the locking latch can be moved via an inductive coil. The locking bolt is there trained such that he can engage in corresponding recordings in the main bolt and can lock it. Both coils are used briefly with electrical energy acted upon, the locking bolt releases the main bolt and the main bolt is shifted accordingly at the same time. If the energy supply is then ended, falls the locking bolt in another recess and fixes the main bolt in the new one Position. With this device, a locking of the main bolt can be achieved, however, it is not possible to determine the state of the locking system.

  • WO 89/11016 A1 is a locker system with several mechanical Locks described lockable lockers.
  • An additional lock is assigned to the mechanically actuated lock, that via a disc-shaped, remotely operable locking member depending on one Access authorization releases or covers the keyhole.
  • the locking member can several sensors are assigned, which detect the position of the same and output corresponding control signals to a control device.
  • the disadvantage is that the additionally attached lock needs its own energy supply and therefore to lay additional power supply or signal lines are.
  • the present invention is therefore based on the object of a locker system to create the type mentioned in the simple way by monitoring devices a simple determination and display of the operating states achieved becomes.
  • a major advantage of the claimed item or Method according to claim 1 or 23 is that to determine the current Operating state of the locker not only a movement of a sub-component of the lock is required and at the moment of this movement the changes of the Inductance of the coil must be recognized, but rather the static state or the static inductance of the coil for determining the operating state of the locker is used. This makes it possible that the operating status of the lockers continuously monitored and checked in succession at relatively short intervals can be. Because there are no movements to identify the locker status can be required at any time with the system according to the invention Subject status of any locker can be queried.
  • the energy consumption can be kept low because with the locking bolt no closing or locking process has to be carried out, but only the locking bolt for a short period of time during the operation of the lock, must be acted upon and, moreover, is advantageously a simple one Detection and display of the operating states in monitoring devices reached.
  • An embodiment variant according to claim 2 is also advantageous, as a result of which only over the period of time over which authorized access to the safe or locker it is possible to apply the electromagnet.
