Description

Locking factories with several lockers

The invention relates to a locker system with several

Lockers, each with its own door, which has a locking device with a mechanical lock.

Various locker systems are already known which consist of a large number of lockers, in which each individual locker is provided with its own door and which can be locked by means of a locking device. Such lockers, also called security deposits, are often used in banks in order to enable badrik customers to store valuables without the bank's control. In order to achieve security against unauthorized opening of a locker, these doors are usually provided with two mechanical locks, a so-called customer lock and a bank lock. This ensures that the customer can only open the locker after proof of access authorization and that, in addition to the customer key, there is therefore additional security against unauthorized opening. The so-called bank lock is unlocked after an identity check by a bank official accompanying the customer, whereupon the customer can open the locker with his key. It is disturbing for many customers that the bank clerk who is also present in the locker room can observe the customer's transactions. Accordingly, not least because of the high personnel costs, the banks tried to automate the access to such locker systems.

Locker systems are therefore known in which one of the two locks in the door, namely the bank lock, can be released by remote control device by a bank official who has his workplace outside the sci-locker system. Such a lock is known for example from EP-OS 0 096400. By additional It is guaranteed that if the bank clerk releases the data incorrectly after a short time, the bank lock will automatically come up again automatically, so that a later attempt by a customer to enter a locker with a false key will fail. In addition, various security measures, such as motion detectors, infrared sensors and other, are arranged to secure the locker system, as is also the case with other safe systems. A disadvantage of such locker systems is that either the personal effort for operating the bank lock is relatively high, or when using the currently known locks the energy for actuating the electrically operated locks is relatively high. This requires extensive electrical installations, so that these systems are not suitable for retrofitting doors with two mechanical locks in a locker system. In such systems, all the doors in the locker system would have to be exchanged and separate wiring installed. The outlay for this is relatively high and there is also a major problem in that it is not always possible to call all customers on a certain day in order to outsource the valuables stored in the lockers, so that the conversion is carried out can.

The present invention is therefore based on the object of creating a locker system of the type mentioned at the outset,

± n the locker systems, which in particular were simple, could be equipped with mechanically operated locks in such a way that the so-called bank lock can be operated remotely, without requiring a lot of energy. In addition, it should be possible to convert existing locker systems without having to replace the doors and having to install a complex wiring network.

This object of the invention is achieved in that the locking device comprises an additional lock assigned to the lock, which has an electric drive for a locking device and that the locking device blocks access to the mechanical lock and / or its adjustment

Rest position and an open position which releases this access and / or the adjustment. As a result, it is now advantageously achieved that access to or actuation of the mechanically actuated customer lock is prevented via the additional lock. This measure, which appears to be relatively simple, ensures that the energy expenditure for the actuation of the locking device of the additional lock can be kept very small, since no "locking function" of the lock has to be carried out. In addition, it is made possible in a surprisingly simple manner that any locker system with any lock system can be easily equipped with the new additional lock.

According to another embodiment it is provided that the additional processing locks of the individual lockers with a Steuereinrich¬ and or or a central control unit are connected, whereby a central monitoring and operation of the fan and thus Schließ¬ edLne increased security against a unberechtig¬ tes ^" Opening such lockers is achieved.

However, it is also possible for the additional lock to be arranged on the outside of the door facing away from an interior of the locker and to be connected to it by means of fastening means, so that in the case of doors with mechanical locks without an additional structure inside and thus without narrowing the interior the lockers the additional lock can be attached.

Furthermore, it is also possible for the additional lock to be fastener is attached to the door of the locker in front of a key hole of the mechanical lock. This means that the additional lock can be easily installed with a door, even if it was originally provided with two mechanical locks, and the additional security is made possible by the remote-controlled adjustment in the additional lock.

However, it is also advantageous if the fastening means is formed by a self-adhesive layer of adhesive arranged on the additional lock, since this means that no mechanical processing of the door of the locker is necessary.

Furthermore, it is also possible that the fastening means is formed by a cooperation with the mechanical lock in the door of the holding member, since this allows the second mechanical lock to be used to fasten the additional lock according to the invention.

It is also advantageous, however, if the locking device has a rotary latch which comprises an actuating button protruding from the additional lock and an opening in a locking plate, which is arranged on the rotary latch and that the locking lugs have an opening position aligned with the opening and have a rotated closed position relative to this and that the locking bolt has a locking device with a spring device which exerts a biasing force directed in the locking position of the rotary bolt and is assigned to a locking element which interacts with a bolt and a drive, since with Additional mechanical security can be achieved with minimal effort, which can nevertheless be easily adjusted from the locked to the unlocked position using a drive that requires only a low energy.

Furthermore, it is also possible for the locking device to have an adjustable locking pin which is arranged perpendicular to the door and which, via a spring device, is loaded with a pretensioning force directed against a locking bolt of the mechanical lock in a rest position engaging in the locking bolt and is held in this by means of a locking member to which an electric drive which is mounted so as to be adjustable perpendicular to the locking pin is assigned. As a result, it is easily possible for the locker user to engage the second security, namely the bank security, himself after the end of his manipulations by pushing the locking bar in the manner of a push button.

Furthermore, however, it is also possible for the locking device to have an adjustable locking pin arranged perpendicular to the door, which can be locked against one another by means of a spring device

Locking bolt of the mechanical lock biasing force held in a locking position engaging in the locking bolt and adjustable by a drive against the action of the spring device, whereby the force required to unlock this additional mechanical lock is limited to the retraction of a locking pin and is therefore not remotely controllable , so that a manual operation can be easily replaced.

According to another embodiment variant, it is provided that an opening of the locking device passing through the additional lock perpendicular to a door surface is arranged congruently with the keyhole of the mechanical lock, since the key previously used for the mechanical customer lock can thereby be used further.

In addition, however, it is also possible for the additional lock to have at least one cover which is adjustable relative to the keyhole and is connected to the drive. This embodiment is characterized in particular by the fact that only the energy necessary for adjusting the diaphragm has to be applied, which, with a corresponding design, for example by means of a central lock or by a key lock corresponding to the design of a camera, only in a correspondingly more solid design, which can constitute an additional bank block.

It is also advantageous if a drive is assigned to several additional locks of several doors, which is in a relative is arranged to these adjustable actuating device, since the effort for the additional securing of the doors of the lockers, especially when retrofitting locker systems, which have doors with two locks, is thereby low.

Furthermore, it is also possible for the drive to be motionally connected to a key for the additional lock, which has, in particular, a rest position lying inside the actuating device and a blocking position lying outside the same, whereby a simple mechanization of the activity previously carried out by a bank official can take place.

Furthermore, however, it is also possible for the fastening means and / or the cover and / or the additional lock and / or the actuating device to be associated with the control device. The sensors enable the respective lock state to be determined and, at the same time, can be used to increase security against unauthorized opening of the lockers, which, in addition to the simpler and cheaper operation of the locker

Locker system at the same time. The security standard of such a locker system can be increased.

It is advantageous in this case if the locking device, in particular the diaphragm, is assigned a measuring sensor in the rest position, which is activated when the diaphragm is controlled from the rest position, since the position of the diaphragm thereby serves both to monitor whether the opening of the bank lock is legitimately followed or not, and can also be monitored by an operator of the bank for monitoring the correct function of the bank lock after deliberate opening.

Furthermore, it is also possible that the sensor assigned to the additional lock is activated at a distance from the door of the locker. The arrangement of a transducer makes it possible in a simple manner to monitor the position of the additional lock relative to the door, so that an adequate mechanical fastening device is also required Security against unauthorized removal of the additional lock forming the bank lock can be achieved.

According to another embodiment, it is provided that the control device or the specialist computer via conversion components, e.g. Modulator or demodulator, is connected to a communication system for energy and / or signal transmission between the specialist computer or the Stexj device and the energy source and / or a central control unit. As a result, the expenditure for energy supply and message transmission in such a locker system can be reduced.

It is advantageous if the communication system is formed by a line connected to the control devices, insulated with respect to the armored wall, and the armored wall of the locker system, since as a result the necessary is required with only a single wire or line Energy and the control signals for a large number of locks can be transmitted.

According to another embodiment, it is provided that the line is formed by a conductor track arranged on the doors of the lockers with an interposed connection, whereby the laying of additional lines in existing locker systems can be saved.

It is possible here for the conductor track to consist of an electrically conductive, in particular semiconductive, plastic, by means of which the line to be applied can be produced in the manner of a design or painting, so that its actual function is not immediately apparent to an outsider .

Furthermore, however, it is also possible for the conductor track to be connected between the doors and / or the body via contact devices, which facilitates the connection of several additional locks of a locker system to an entire network.

According to another variant, it is provided that the line is formed by a light guide and transmission links for the wireless connection of light guides are arranged between the doors and / or the armored wall, whereby a seamless connection between the adjoining light guide parts can also take place when a door is opened with an additional lock. In addition, the cross section required for such light cables is small and powerful, so that both higher energies and a wealth of information can be transmitted simultaneously.

It is advantageous here if the transmission members are provided with a pivotable optic, since this allows transmission in the joint area of the door between the door and the body.

According to another embodiment, it is provided that two conductor tracks are provided and a conductor track arranged on the door is interconnected with the one when the door is closed and with the other conductor track when the door is open, so that a perfect connection both when the door is open and when it is closed to the energy and news supply system is ensured.

Furthermore, it is also possible for the contact device to be formed by contacts arranged on the door and a carcass forming a wall of the body or in alignment with one another between the doors, which means that the state of the door, whether it is closed or not, is immediately disconnected by interrupting the connection or. open, can be displayed after an energy and message supply is only necessary in the closed state of the door anyway, so that the door can only be allowed or opened in the event of an interruption. However, on the basis of the release by the bank official, it can be determined whether the opening took place correctly or not.

Another advantage is an embodiment in which the communication system between the additional locks and the energy source and / or the central control unit takes place wirelessly, since this completely eliminates the need to produce conductor tracks in the area of the body or the lockers, with the use of a corresponding energy storage unit in the additional lock, even brief interruptions in energy and message transmission by a customer cannot interfere with the overall function of the additional lock.

According to a further embodiment it is provided that the contact device is formed by inductive or capacitive transmission devices arranged on the door and on the body or its wall, since this enables simple, contact-free transmission of the energy and the information .

According to another further development, it is provided that the communication system has a receiver connected to a control device and a transmitter distanced from it and connected to the energy source and / or the central control unit for carrier radiation and / or oscillations and / or force fields, such as Has heat, light, sound, magnet or the like. As a result, the supply of the additional locks arranged on the individual doors can take place from a central point, but this supply is not disturbed by the opening of individual doors in the locker system.

It is advantageous here if the communication system between the energy source and the additional lock comprises a light transmitter and a light receiver, in particular for infrared light, since the light source which is already present in such systems can be used for energy and nadir directional transmission and it is a relatively inconspicuous and not immediately apparent to the customer supply unit, which also requires little effort when retrofitting such locker systems.

It is advantageous here if the conversion component of the communication system between the central control unit and the additional lock has connecting elements for superimposing the carrier beams with information and for sifting out the information from the carrier beams, since this results in different frequencies in the light spectrum or energy transfer can be used simultaneously and an additional medium is not required for this task.

It is also advantageous if the additional lock covers the keyhole for the lock arranged in the door and optionally the additional lock, since after removing the additional lock the second lock can be used as an emergency actuation for the bank.

However, it is also possible for the additional lock or a group of additional locks to be connected to an input and / or reading device, since this can keep the control engineering outlay for managing the lockers which are provided with retrofitted additional locks low.

However, it is also advantageous if the lines of the communication systems are arranged in a housing of the additional lock, since this can reduce the wiring effort in the area of the locker system to a minimum.

Finally, it is also possible for the housings of the additional locks to be connected to one another by adjoining doors via contact devices, whereby the additional locks not only provide the security function for the bank lock, but also the necessary facilities and systems for Energy supply and transmission of messages can record.

For a better understanding of the invention, it is explained in more detail below with reference to the exemplary embodiment shown in the drawings.

In Fig.l a locker system 1 with a plurality of lockers 2 is shown in a simplified schematic diagram. The locker system 1 is arranged, for example, in a vault 3 of a bank 4. Access to the vault 3 is possible via an access door 5, which can be formed, for example, by a lattice door or by a reinforced door during the night. To enable access to the locker system 1, a control point 7 is set up in the anteroom 6 of the vault 3 or in another room of the bank. This includes a monitor work station 8 and possibly a card reader 9. The monitor work station 8 and the card reader 9 are connected to a central control unit 11, for example, via a data line 10. A log printer 12 and another card reader 9 in the area of the access door 5 are also connected to this central control unit 11. The locker system 1 is also connected to the central control unit 11 via a bus system 13 or, in the case of smaller systems, a corresponding data cable. Each of the lockers 2 is closed with a door 14, which is associated with a locking device 15. This locking device 15 has a mechanical Castle 16.

If a user or owner of a locker 2 wants to visit his locker, he must identify himself, for example at the screen workstation 8, by inserting a control card made available to him in the manner of a check card or the like into the card reader or one of the Filled out and signed the form prepared by the clerk. The counter clerk then has the option of entering the respective customer number or the name of the user via the image screen workstation, whereupon the corresponding signature or personal data, for example a photo or the like, are presented to him on the screen, so that he can carry out a personality check . If the check is positive in accordance with the security regulations, the bank officer can release the respective locker 2 for access by the user via the screen workstation and the central control unit 11. The user then goes into the area of the access door 5 where, after checking the access authorization again using the card reader 9, he or she can gain access to the safe room 3. * In the safe room 3 he can now use his key to belong to him Open locker 2, whose additional lock 17, shown schematically by a box, has been unlocked via central control unit 11 or from workstation 8. This additional lock 17 is usually referred to as a bank lock.

2 shows an embodiment of a locking device 15 for a door 18 of a locker 2. These lockers 2 are installed in a body which is formed from armored walls 19, between which the doors 18 are inserted, which in turn are fastened to the armored walls 19 via hinges 20. This locking device 15 comprises a mechanical lock 16. To actuate the mechanical lock 16, a key hole 21 is arranged in the door 18, via which a key 22 can be inserted into a locking mechanism 23. The locking mechanism is in movement connection with a locking bolt 24. The closing movement of the locking bolt 24 can if necessary durc a spring 25 are supported. An additional lock 26 has a locking pin 27, which is adjustably mounted perpendicular to the door 18 and passes through the door 18 and a bent area of the armored wall 19 and engages in a bore 28 in the locking bolt 24. The locking pin 27, which acts as a bolt, is connected to a drive 29, which is designed, for example, as an electromagnet. The locking pin 27 is biased against the action of the drive 29 by a spring device 30 so that it engages securely in the locking bolt 24. The additional lock 26 is fixedly connected to the door 18 via fastening means 31, for example an adhesive layer 32.

The drive 29 is connected to a control device 34 via lines 33. The control device 34 is assigned sensors 35 and 36 with which the position of the additional lock 26 relative to the door 18 can be continuously monitored or with which the ambient temperatures or vibrations can be determined in order to determine whether an unauthorized person is trying to log on to gain access to a locking axle 2 by using the weight. These transducers 35 and 36 are preferably attached to a printed circuit board 37 or a computer board that supports the staging device 34. The computer plate can, of course, also be formed by a cast component which is provided with standardized plug devices. It is connected via a conversion component 38, for example with a solar cell arrangement 39, which in turn forms part of a communication system 40 - FIG. 3.

As can be seen better from FIG. 3, the communication system consists of radiators 41, which are connected to an energy source 42 and to the central control unit 11 or any other control computer. The energy required for the activation of the drive 29 is symbolically indicated by light rays 43, the signals 44, which are indicated schematically by a wavy line in the drawing, being superimposed on these light rays 43. This superimposition can take place both for signal transmission from the emitters 41 to the conversion component 38, and also in the opposite direction. The signal Communication between the conversion component 38 and the radiator 41 for forwarding signals to the central control unit 11 is therefore important in order to give an alarm or a notice to the operator or the bank as quickly as possible in the event of malfunctions or attempts to open by unauthorized third parties, so that possibly an illegal opening of a locker 2 can be prevented as quickly as possible.

In FIG. 4 it is further shown that the solar cell arrangement 39 can be equipped with scale-like arranged solar cells 45. It is particularly advantageous if the individual solar cells are inclined at an angle 46 with respect to a vertical, which corresponds to an angle of incidence of the light rays 43, so that the best possible energy yield from the light rays 43 can be achieved or the signals can be received well 44 is ensured. Of course, it is also possible that the solar cells 45, as shown in FIG. 3, are arranged parallel to the doors or that the angle is 4690 degrees.

Another embodiment variant for an additional lock 26 is shown in FIG. As described with reference to FIG. 2, the door 18 is rotatably arranged on hinges 20 on armored walls 19. A mechanical lock 16, which is firmly connected to the door 18, is arranged on the side of the door IS facing away from the operator. To operate the lock 16, a key 22 is provided which can be inserted into the lock 16 via a keyhole 21. Any known mechanical lock with a sufficient degree of security can be used for such purposes for the lock 16. This mechanical lock 16 came - as indicated schematically - also to be provided with an additional lock 47 connected in parallel with the locking direction 15. If, in order to facilitate the operation according to the invention, this additional lock 47 is to be replaced by a ferr operation, a housing 48 of the additional lock 26 is built in front of the keyhole 21 of the additional lock 47, for example. As indicated schematically, the housing 48 can be connected to the door 18 with fastening means 31, for example mechanically via fastening screws 49. be that. The additional lock 26 comprises a locking device 50. This has, inter alia, a rotary latch 51 arranged perpendicular to the door 18. When the door 18 is closed, locking lugs 52 penetrate the armored wall 19 and can be pivoted with respect to an opening 53 into the position drawn in full lines, in which a distance of the most distant points of the two locking lugs 52 is greater than a width the opening 53. A height of the opening 53 corresponds essentially to this distance from the points of the locking lugs 52 which are most distant from one another or is slightly larger. The rotary latch bearing the locking lugs 52 is further connected to an actuating button 54 projecting beyond the housing 48, so that the rotary latch 51 can be actuated from outside the locker 2. A locking member 55 is also connected in a rotationally fixed manner to the locking bar 51, as is indicated schematically by weld seams between the locking bar 51 and the locking member 55, which can be formed by a washer.

As can also be seen better from FIG. 6, the locking member 55 is connected in an articulated manner to a spring device 56 which is mounted in the housing 48 with its end facing away from the rotary latch 51. With this spring device 56, a pretensioning force, schematically indicated by an arrow, in the closed position is exerted on the rotary latch 51. The spring device 56 therefore tries to always keep the locking lugs 52 in their position corresponding to the closed position and shown in full lines in FIG. I now to allow actuation of the rotary latch 51 only when an authorized user opens the door 18 of his locker 2 .11, a locking device 57 is provided. In the example shown in FIG. 6, this consists of a drive 58, e.g. e. a piezo drive and a bolt 59 which interacts with it and, in its rest position drawn in full lines, engages in a recess in the disk-shaped locking member 55. Now an unauthorized user tries the rotary latch 51 in with the actuating button 54

To turn the opening direction, this is not possible, since a rotation of the disk-shaped locking member 55 is prevented by the bolt 59. On the other hand, if the bank has access to the Locker 2 released, current is supplied to the latch 59 via the control device 34, that is to say that it deforms in the direction indicated by dashed lines due to the inherent material properties. It therefore moves out of the circumference of the disk-shaped locking member 55, and the rotary bolt 51 can now be adjusted against the pretensioning force indicated by the arrow in an opening position in which the locking lugs 52 can pass through the opening 53. If the authorized user previously unlocked the mechanical lock 16 with the key 22, he now has free access to his locker 2. The control device 34 can be supplied via lines, or it is also possible to transmit the energy and signal by means of the Carry out rays -43 as described in more detail with reference to FIGS. 3 and 4. In this case, 48 solar cells 45 would have to be arranged on the housing.

In order to prevent the additional lock 26 from being removed from the door 18 in an unauthorized manner or to be able to monitor the desired position of the disk-shaped locking member, a plurality of sensors 60 to 62 are arranged. The transducer 60 monitors the position of a control pin 63 on the disk-shaped locking member 55. If the control roller 63 is rotated from the position shown, the transducer 60, which can be formed, for example, by an electromagnetic proximity switch, can be activated and activated e ^ corresponding control signal to the control device 34. The measured value transmitter 62 can be designed similarly to the measured value transmitter 60 in order, for example, to monitor whether the additional lock 26 maintains its preset position with respect to the door 18. If the additional lock 26 is removed from the door 18 without authorization, the magnetic field changes and the control device 34 can be informed with a corresponding monitoring signal, so that an external alarm can be triggered. The transducer 61 can be a vibration sensor combined or separate from a temperature sensor, so that vibrations that are not permissible, such as would occur when a locker was opened or opened, or at temperature values above the permissible temperatures due to a welding process or the like, a signal is also passed on to the control device 34, which leads to an external alarm triggering. Of course, instead of the piezo drive, any other corresponding element that can be adjusted by the action of temperature or current, for example also made of bimetal or memory metal, can be used.

A variant of the locking device 57 is shown in FIG. In this embodiment variant, the disk-shaped locking member 55 is assigned a locking pin 64 which can be adjusted radially to the disk-shaped locking member 55 against the action of a spring 66 via an electromagnet 65. The locking pin 64 can also simultaneously form the movable core of the electromagnet 65. If the electromagnet 65 is now activated before an authorized opening of the door 18, the locking pin is drawn into the electromagnet against the action of the spring 66 and the movement of the rotary latch 51 is released. This makes it possible to move the rotary latch 51 - as described with reference to FIGS. 5 and 6 - into an open position counter to the action of the spring device 56.

Another embodiment of an additional lock 26 is shown in FIGS. In this embodiment too, the additional lock 26 is built on the door 18 of a locker 2. Each door 18 of a locker is connected to the armored wall 19 via hinges 20. The armored walls are angled and are engaged by the locking bolt 24 of the mechanical lock 16. As a result, the door 18 can be locked in its closed position with respect to the armored wall 19. In order to supply power to the additional lock 26, conductor tracks 67, 68 are arranged on the armored wall 19 or on the side of the door 18 facing this. The conductor track 67 on the door 18 is connected via lines 69 to the additional lock 26 or the control device 34 arranged therein. The mechanical

Lock 16 can be formed by any known mechanical lock from the prior art, so that with the additional lock 26, doors 18 of lockers 2 in particular can be equipped, which are equipped with a normal double lock for a so-called "bank key" and a "child key". The keyhole 21 originally provided for actuating the "bank lock" is preferably covered by the additional lock 26. An opening 70 for the actuation of the "customer lock" is passed through the additional lock 26 so that the bank customer can lock the lock 16 after the attachment of the additional lock 26 with his previously used key through the additional lock 26. The additional lock 26 can be fastened on the door 18 by screwing, gluing or welding.

9 and 10, only the design and arrangement of the conductor tracks 67 and 68 is shown on a larger scale. Each of these conductor tracks 67 and 68 forms a coil, which coil can be produced from a conductive adhesive tape or can be sprayed onto an insulating film 71 with conductive paint. This film 71 can be glued directly on the side of the door 18 facing the armored wall 19 and can be contacted with the lines 69 passing through the door 18. However, it is also possible for the conductor strip to be wound around the door 18, as indicated schematically by dashed lines in the area of the additional lock, so that drilling through the door 18 can be avoided and the control device 34 directly on the outside of the door Door 18 can be contacted with the conductor track 67.

In order now to supply the coil formed by the conductor track 67 with energy by induction, the conductor track 68 on the armored wall 19 likewise forms a coil which is formed via lines 72 which are likewise formed by conductor tracks applied to self-adhesive films or by self-adhesive conductor films can be supplied with an energy system. By appropriately supplying the coil formed by the conductor track 68 with alternating current, a voltage is induced in the conductor track 67 and in the coil formed therefrom, which voltage leads to

Energy supply of the auxiliary lock can be ^"used 26th Through appropriate modulation of the AC voltage can in this way in addition to energy, information and Control signals are transmitted from a central control unit to the control device 34.

The structure of the additional lock 26 is shown in detail in FIG. A locking member 73 is formed by an aperture 74 which is provided with teeth 75 at least over part of its circumference. The aperture 74 is mounted rotatably about an axis 76. In addition, it has a recess 77 which, when the diaphragm 74 is in the open position - as shown in FIG. 1 - is congruent with the keyhole 21. On the

Locking member 73 is further provided a control pin 63, which can also be formed by a glued-on metal foil or a metal part built into the locking member 73, which in the position of the locking member 73 shown is assigned to the transmitter 60, with which the position of the aperture 74 is monitored can be. The measuring transducer 60 is connected to the control device 34, as are further measuring transducers 61, 62 - which may have the same or the same function as described with reference to FIGS. 5 to 7. The control device 34 is supplied with energy and with signals or messages via the lines 69 from the conductor track 67 designed as a receiving coil. For this purpose, the lines 69 are passed through an opening in the door 18. A drive 78 for a gear 79 is also connected to the control device 34. This drive can be formed by a stepping motor or a disk-shaped linear motor or any other motor. It is advantageous if this motor has a very low overall height, since then the additional lock 26 can also be produced with a very low overall height.

The function of the additional lock 26 is now such that when the lock 16 is released with the drive 78, the aperture 74, for example, from a position in which the recess 77 is a position shown in broken lines, in which the access to the keyhole 21 through the Aperture 74 is closed, with the drive 78 is pivoted into the position of the recess 77 drawn in full lines. Reaching this end position is the interaction between the control pin 63 and the Sensor 60 monitors. Furthermore, a transducer 80 can also be arranged in the area of the recess 77. The interaction of the measuring transducers 60 and 80 then makes it possible to precisely monitor the respective position of the diaphragm 74, by signaling the closed or the blocked position of the diaphragm 74 when the output of the measuring transducer 80 is occupied, while when in the open position. Indian aperture 74, the output of the transducer 60 is assigned a signal. At the same time, the transmitter 80 can be used to monitor the presence of a key when the aperture 74 is in the open position. This would mean that, when the sensors 60 and 80 emit signals simultaneously, the aperture 74 is in the open position and a key is inserted into the keyhole 21. At the same time, this monitoring could be used to ensure that according to the

Locking the lock 16 and removing the key from the keyhole 21 automatically the keyhole 21 can be locked immediately by the aperture 74. This would additionally shorten the period in which an unauthorized user could manipulate the lock. When using a flat drive 78, it is therefore possible to design the additional lock 26 in the manner of a somewhat thicker check card. This can then be applied more easily to the door 18 by an adhesive process. Instead of the motor 78, it is of course also possible to provide a drive by means of a rotary magnet, or the keyhole 21 can also be blocked by locking pins actuated by a magnet.

Another embodiment variant for an additional lock 26 is shown in FIGS. This additional lock 26 is, as can be seen better from FIG. 13, again attached to the side of the door 18 facing the user. The design of the additional lock 26 can essentially correspond to the embodiment of the additional lock 26 according to FIGS. 8 and 11, so that the same reference numerals are used for the same parts. The doors 18 are fastened by hinges 20 to the armored walls 19 or in the armored frame. On the inside of the locker 2 facing the side of the door 18 there is a mechanical lock 16 which ches is lockable by a key that can be inserted through a keyhole 21 through the door 18 into the lock 16. Access to the keyhole 21 can be prevented by a locking plate 81. This locking plate 81 is designed in part of its area as a movable armature 82 of a linear motor 83, to which the stator 84 are assigned. The linear motor 83 forms the drive 78 for the locking plate 81. By reversing the stators 84, the locking plate 81 can be moved alternately in the direction of the keyhole 21 or away from it. This enables the keyhole 21 to be released or closed using simple means, which also offer the advantage that they require only a small structural depth.

A communication system 85 between the central control unit 11 and the control devices 34 assigned to the individual additional locks 26 is formed by conductor tracks 86, 87. These conductor tracks 86, 87 consist, for example, of an electrically conductive, in particular an electrically semiconductive, plastic which is applied to an insulating layer 88. This application of the insulating layer 88 and of the conductor coverings 86, 87 to the doors 18 can be carried out by spraying or vapor-coating the individual layers successively on the doors, or it is also possible to apply the insulating layer 88 and the conductor track 86 to be formed as a preferably self-adhesive film tape, which is then applied only to the fronts of the doors and to their front edges 89.90. Contact devices 91 are arranged between the individual doors 18 for connecting the conductor tracks 86 between the individual doors or for connecting the conductor tracks 86 to a armored wall 19 which forms the body of the locker system. This

IContact devices can, for example, have spring-loaded contacts 92 in order to come into contact with the conductor track 86 in the region of the end edge 89. This ensures an undisturbed connection between the conductor tracks 86 and sufficient security in the transmission of energy and messages between the individual doors 18. As indicated schematically in FIG. 12, the conductor balls in the area of the additional lock 26 are coupled to an energy store 93. This energy storage 93, which can be formed by a battery or the like, is used as a so-called buffer memory, so that certain functions of the additional lock 26 can also be carried out in the open state.

14 shows how an adequate supply of the individual control devices 34 in the additional locks 26 can also be ensured when a door 18 is opened. For this purpose, 19 conductor tracks 94 are arranged on the body or the struts or armored walls, for example in the area of the doors 18 below

Interposition of an elastically deformable carrier layer 95 can be arranged on the armored wall 19. Through this parallel connection, the conductor track 94 arranged on the armored wall and the conductor tracks 86 on the doors 18, a connection and supply to the other doors 18 can be maintained even when one of the doors 18 is opened. Of course, however, it is also possible to design the conductor tracks 86 and 87 in multiple tracks, so that the supply and supply of the individual control devices 34 to the doors 18 can take place from any side, or it is also possible by means of appropriate control logic in the central control unit 11 to prevent, for example, in a row of lockers 2 arranged one below the other, more than one locker 2 being released for access.

15 shows a line 96 which can be used to produce the conductor tracks 86, 87. This line consists of an insulating layer 88 forming a support layer, onto which a self-adhesive layer 97 is applied on one side and conductor tracks 98, 99 and 100 are applied on the opposite side. Of course, a plurality of conductor tracks can also be arranged parallel to one another on this insulating layer 88. It is thus possible to separate the signal lines from the energy supply lines or to set up different circuits via which the individual doors are supplied, for example alternately.

In Fig.16 another kind of KOTirri unation system 85 is Supply of the lockers 2 of a locker system 1 shown on the doors 18 of lower lockers 2 arranged side by side or side by side. Additional locks 26 are arranged on the doors 18, which can be designed, for example, in accordance with the above-described embodiments. The .Kcιr «ταjnication system 85 is now carried out wirelessly to supply power to the individual additional locks 26. The transmission of energy and information or messages takes place between the additional locks 26 via transmission elements 101, 102 arranged facing each other in the additional locks 26. In the simplest embodiment, these transmission elements can be formed by transmitting and receiving optics for light guides 103 connected to them. However, it is of course also possible that these are light-emitting or laser diodes as transmitter units and corresponding light-sensitive elements as receiver units. This makes it possible to follow different signal sequences and also to transmit energy. The energy transfer can take place by light waves, magnetic waves or by induction. In the latter case, the transmission elements 101, 102 are formed by appropriately designed coils.

The transmission elements 101 and 102 are interconnected with the control device 34 arranged in the respective additional lock, to which, for example, a keyboard field 104 can also be connected. Various information can be entered into the control device 34 via this keyboard field 104. The advantage of such an arrangement is that there is double security for the user of a locker 2, since in addition to his "customer key", a personal code can also be entered into the control device 34 without the locking plate 81, for example, the keyhole 21 does not release.

Another embodiment variant for the automation of an existing locker system is shown in FIGS. The existing system consists of locking compartments 2, the doors 18 of which are locked via a mechanical lock 16. The lock 16 has two mechanical locking mechanisms, the so-called additional lock 17 and the locking device 15. This locking mechanism can either have two separate or a common keyhole. Almost all existing non-electronic locker systems are constructed in this way. A group of doors 18 is assigned only one common actuation device 106, which is remotely controlled from the bank's operator station and can actuate the additional lock 17 of the locks 16. To actuate the bank lock, a drive 107, for example a rotary drive, is present on the actuating device 106. The rotary drive is non-rotatably connected with a key 108. The drive 107 with the key 108 is connected in a guideway 109, which is aligned perpendicular to the door fronts of the doors 18, with an adjusting drive 110. With this infeed drive 110, the drive 107 can be inserted with the key 108 into the keyhole 21 of the additional lock 17. If the key 108 is locked in the additional lock 17, it can be pivoted into an open position by the drive 107. The additional lock 17 is thus unlocked. The key 108 with the feed drive 110 can then be removed from the keyhole 21 and the actuating device 106 can move to a rest position away from the locker 2 to be opened. In order to enable a movement along guideways 111 into a rest position even if doors 18 that are open during this movement, as shown in FIG. 17, are to be passed, a support arm 112 of the actuating device 106 can be made up of a the doors 18 adjacent position close to a distant position. For this purpose, the support arm 112 is arranged on pivot axes 113 of carriages 114 which can be moved in the guideways 111. A swivel drive 115 is provided for swiveling the support arm 112 around the swivel arm 113, and is rotatably coupled to one of the two swivel axes 113.

Through this central actuating device 106, it is now possible to automate existing locker systems 1 with a large number of lockers 2, which are secured by two mechanical locks, so that bank personnel are no longer required to assist the customer when his locker is opened must accompany. The bank lock can now be opened via the central actuating device 106 before the customer enters the locker room, whereupon he can unlock the locker with his customer key. The "bank lock", which is formed by the additional lock 17, either engages automatically when the "customer lock", namely the lock 16, is locked, or, after the customer has left the vault, can be closed again fully automatically by the actuating device 106 become.

19 and 20 show another embodiment of a central fastening device 116 for a plurality of additional locks 17 arranged in doors 18 of lockers 2. This essentially consists of a robot 117 which can be moved along a guideway 111. For moving along the guideway 111, the robot is provided with a travel drive 118 which, for example, consists of an electric motor with a flanged-on gearwheel, which in a rack 119 arranged on the guide track 111 engages. A working head 120 of the robot 117 can be adjusted via a height adjustment drive 121, for example formed by a telescopic cylinder, to the additional lock of the door 18 to be opened in each case. The positioning of the working head 120 along the guideway 111 takes place via the travel drive 118. In the working head there is a drive 107 for the key 108, which in a

Keyhole 21 engages the additional lock 26, arranged. After the working head 120 is centered on the keyhole 21 of the additional lock 17, it can be inserted into the keyhole 21 via an auxiliary drive 110 and then rotated with its drive 107 into its open position. If the additional lock 26, which forms the "bank lock", is thus open, the key 108 can be pulled out of the keyhole 21 by means of the feed drive 110 and the robot 117 can be moved into an end position.

The design of the robot 117 or its height adjustment drive 121 makes it possible to lock the working head 120 into an area after the additional lock 26 has been locked or unlocked to be lowered below the locker system 1 so that it can be moved into a predefined rest position without risk of collision with an open door 18.

Under certain circumstances, it is also possible to arrange the working head 120 on a swivel arm 122, so that the robot 117 can maintain its position which it has taken to open the additional lock 26 and the working head 120 only - as indicated by an arrow 123 - into the position drawn with dashed lines can be pivoted so that access to that door 18 in which the additional lock 17 has been unlocked is free.

21 shows part of a door 18 which is provided with two key holes 21 for mechanical lock 16 and an additional lock 17. In order to enable centering of the working head 120 or the key 108 with the actuating device 106 or 116, markings 124 relating to the keyhole 21 are arranged adjacent to the keyhole 21, which have sensors in the working head 120 or on both sides of the key 108 can be scanned in order to enable the key 108 to be inserted correctly into the keyhole 21 of the lock.

In Figures 22 and 23 the possibility of wireless

Energy transmission via electrical, magnetic or electromagnetic fields shown. This principle is of particular importance for the automation of existing, purely mechanical lockers, since little intervention in the existing system is necessary.

22 shows a locker system 1 in plan view, along the walls there are lockers 2. In the middle of the room, the arrangement of antennas 125 is indicated, which radiate energy for supplying the additional locks 26 as well as that for Control of the locks emit the necessary signal data or receive the response signals of the additional locks. These antennas are in turn tral control unit 11 connected. Lines 126 indicate the area irradiated by the antennas.

Another solution variant according to the invention is shown in FIG. The picture shows a wall of the locker system 1 with the lockers 2. The additional locks 26 are located on the doors 18. A ratio antenna 127 is now placed around this block of lockers, which antenna is in turn connected to the central control unit and both energy as well as emits data and at the same time receives data from the additional locks. The additional locks 26, which can be implemented in one of the variants described above, also have an integrated antenna, e.g. in the form of a coil similar to Figure 9, which interacts with the loop antenna 127 and thus accomplishes the data and energy transmission.

A block diagram of a control device 128, as indicated schematically in FIG. 1, is shown in FIG. This control device comprises an image workstation 8 formed from a screen 129 and an input keyboard 130, a mass memory 131 and one or more log printers 12 for logging the individual control processes; the link between the image screens 129, the input keys 130, the mass storage 131, and the log printer 12 and the output of the corresponding control commands to a network controller 132 is carried out via the central control unit 11. Each individual locker 2 is connected to this network controller 132 ¬ arranged specialist computer, one of which is designated 133, connected via lines 134. With a corresponding design, up to 2048 specialist computers can be connected to each network controller. The network controller 132 can be connected to the specialist computers 133 via a four-wire safe bus 135 with a power supply and half-duplex data transmission, for example RS 422. The central control unit 11 can be connected to the screen 129 or the input keyboard 130, as well as the mass memory 131 and the protocol printer 12, via serial standard interfaces, for example RS 232 or RS 422, or according to a freely definable protocol program. Furthermore, it is also possible to establish the connection between the network controller 132 and the specialist computers 133 assigned to them, as described with reference to the preceding figures, via optical connections, for example modulated infrared light, light guides or via magnetic fields, for example inductively or by radio frequency, for which purpose in particular the representations and explanations relating to FIGS. 3, 9 and 10 and 22, 23 are referred to.

These additional transmission possibilities were indicated schematically by wavy lines between the network controller 132 and the specialist computers 133 assigned to it.

Furthermore, it is possible to connect the central control unit to a mainframe computer system 137 via a serial interface or a further bus system 136.

The basic structure of a specialist computer module 138 is shown in FIG. An energy converter 139 and a data transmitter and receiver 140, which each form a conversion component 38, are supplied with energy or information via the safe bus 135 or an optical or magnetic communication system 40 - which is indicated schematically by wavy lines. These are recorded accordingly and brought into a form that can be processed by the downstream specialist computer 133, the energy being supplied to the specialist computer 133 via a line 141 and the information via a line 142. A drive 144 for an additional lock 26 is optionally arranged on the specialist computer with the interposition of an amplifier 143. Furthermore, 133 transducers 60, 61, 62 and 80 are connected to the specialist computer. The sensor 60 can be used to determine whether the lock is locked or open. With the measuring value transmitter 61, it is possible to determine whether, for example, an undesirably high or inadmissibly high temperature occurs and accordingly, for example, a violent attempt to open it takes place. The sensor 62 can be used to determine whether the door 18 is open or is closed. The sensor 80 can be formed by a capacitive sensor, which acts as a vandal protection. The signals coming from the individual transducers are checked in the specialist computer 133, if necessary validated and sent to the data transmitter and via line 142

Receiver 140 fed. There they are reformatted into the safe bus 135 according to the respective protocol and transmitted to the central control unit 11 via the safe bus 135.

This transmission of the signals from the central control unit 11 to the data transmitters and receivers 140 or from these back to the central control unit 11 can be achieved by a corresponding change in clock pulses.

The sequence of such a control and monitoring method is shown in FIGS. 26 to 28 on the signal sequence in a safe bus 13. Fig. 26 shows a pulse curve, with the voltage in volts on the abscissa and the time in milliseconds on the ordinate. The voltage level in line 142 is e.g. 15 volts, with the specialist computer 133 reducing the voltage in. Intervals of one ms for approximately 0.25 ms to 0 volts via an open collector output. This results in successive clock pulses 148.

This theoretical voltage curve in line 142 is now changed in the form described in FIGS. 27 and 28 when a plurality of specialist computers 133, 145, 146 and 147 - FIG. 24 - are connected to network controller 132. To distinguish the specialist computers, they are provided with an internal system address. For example, the address for the specialist computer 133 is "0", for the specialist computer 145, 146, 147 "1,2,3". In both figures, the voltage curve in line 142 is shown in accordance with the illustration in FIG. The voltage curve in FIG. 27 shows the changes that are caused by the specialist computer 133, while the voltage curve in FIG. 28 additionally shows the changes in the voltage curve that can be caused by the network controller 132. As below using block diagrams of the network Controller 132 and the Fac_hrechner 133 is shown, each specialist computer 133 counts clock pulses 148, whereby to explain the control process it is assumed that a control sequence begins at time t0, ie by the voltage in line 142 rising from 0 volts The specialist computer 133 assigned to the locker with the address "0" knows 15 volts, as shown in FIG. 24 with reference to the right group of specialist computers, that it is addressed. If the locker is no longer properly closed, which is assumed in the present case, the voltage level in the line 142 is increased by the specialist computer 133 after only 0.5 ms, not only after 0.75 ms as shown with dashed lines. lowered to 0 volts. Since the network controller 132 is also present on the line 142, it detects this premature voltage drop and can therefore determine this as feedback from the specialist computer 133 that the door of the locker is properly closed.

After one ms has elapsed, the voltage in line 142 rises again to 15 volts, as a result of which a frequency calculator 145 (FIG. 24) is addressed. Now it is assumed that this

Locker with the .internal address "1" is open, the voltage curve in line 142 remains unchanged, i.e. the voltage of 15 volts is above 0.75 ms. The network controller 132 can thus determine that the door of the locker with the address "1" is open. A clock pulse 149 is therefore unchanged compared to the clock curve shown in FIG.

After the voltage in line 142 has risen again to 15 volts after clock pulse 149, a third locker with internal address "2" is activated in specialist computer 146. It is assumed that the locker assigned to the locker 146 is defective. Accordingly, a clock pulse 150 begins, for example, after 0.25 ms and the voltage in line 142 already drops back to 0 volts after this time. The network controller 132 can now determine that the locker with the address "2" is defective. After the end of the pulse 150, the voltage then rises again to 15 volts, as a result of which a further computer 147 with the address “3” is activated. In this case, as with the specialist computer 133, it is assumed that the door of the locker is open. Accordingly, a clock pulse 151 starts after only 0.5 ms.

It is readily apparent to the person skilled in the art in this field that such a change in the clock pulses or the voltage profile in line 142 can also represent more than the different states described. It is also possible, among other things, to indicate to the network controller 132, for example when the clock pulse is shortened to 0.1 ms, that there is an unauthorized opening of the compartment. On the other hand, however, it is also possible for a specialist computer 133 or 145 or 146 or 147 to emit only one signal or a clock pulse 148 or 151 corresponding to the open door in the event of an unauthorized opening Network controller 132 can be determined based on an internal comparison as to whether there is a release authorization, that the locker can be opened or not. If there is no such release, the network controller 132 is able to deliver a signal that generates an alarm signal to the overall system. It is just possible that the triggering of the clock pulse is not caused solely by the

Closed or open position of the sensor indicating the door, but can also be activated by the other sensors 60, 61 and 80.

Finally, FIG. 28 shows how the network controller can transmit the information for opening the bank lock to the respective specialist computer 133, 145, 146 and 147. This follows from the fact that the supply voltage lying between two clock pulses 148 to 151 is only 10 volts instead of 15 volts, as is the case between the Taltimpuls at time t0 and the clock pulse 148 or the clock pulse 150 and the clock pulse 151 in Fig. 28 is shown. The block diagram of a network controller 132 is shown in FIG. The network controller is connected to an energy source with, for example, +24 volts, via which a microprocessor 152 is also supplied with energy under certain circumstances via corresponding voltage converters or regulators. The line 142 is supplied with a reference voltage of 15 volts from the energy source via a voltage converter via a protective resistor 153. To generate the clock pulses there is a clock control element 154, an opener element 155 and a receiving element 156, which are also connected to the line 142 at the same time. In accordance with the instructions of the microprocessor 152, the clock control element 154, for example a transistor, which drives an open collector, is now driven at a distance of, for example, 1 ms, but this distance can also be smaller or larger and, for example, 5 ms Output 157, which reduces the voltage in line 142 to 0. After the fixed preset cycle length, the application of the clock control element 154 is interrupted, whereupon the voltage in line 142 rises again to 15 volts. If the command or the message that the compartment is to be opened is now to be sent to the addressed locker between two clock pulses, the voltage can be applied via an opener 155, which also has an open collector output 157 Voltage limiting element 158, for example a Z diode, which is set to a threshold value of 10 volts, the voltage in line 142 is limited to 10 volts. This makes it possible to achieve the shape of the voltage curve shown in FIG. 28, a specialist computer 133 being able to recognize from the low voltage in the line that a drive 144 can be opened.

30 shows a block diagram of the specialist computer 133 which is connected to the line 142. A microprocessor 159 is also provided for evaluating the individual information. The entire specialist computer 133 is supplied with voltage via line 142, for which purpose a filter element 160 and a voltage regulator 161 are provided. Furthermore, the microprocessor 159 is connected to the line 142 via two threshold switches 162, 163. This can also be a comparison. dein, each of which is supplied with a reference voltage via an input 164. Depending on the voltage present on the line 142, a signal is now output to the microprocessor 159 via the signal value switch 162 or the threshold value switch 163. After the one at the entrance 164

Reference value for the threshold value switch 162 is set to greater than 10 volts and bedLm Sc_hwellwerttschalter 163 to greater than 5 volts, three different voltage states in line 142, namely voltage 0 volt corresponds to no signal at the input of Sc_hwellwertc ± altern 162 and 163, 15 volts, at least the output of the threshold switch 162 is acted upon and possibly the output of the threshold switch 163 and 10 volts, only the output of the threshold switch 163 is occupied by a signal by which the microprocessor 159 is recognized.

According to the input states defined on the basis of FIGS. 26 to 28, a signal to the line leading from the threshold switch 163 now means that the drive 144 may have to be acted upon via an amplifier 143. By retracting the bolt with the drive 144, the transmitter 60 is activated and transmits the message "bank lock or bolt open" to the microprocessor 159. Correspondingly, the reference voltage of 15 volts is prematurely reduced to 0 with the clock pulse 148 or 151 during the next polling cycle, in the case of a longer response time of the drive 144. This takes place again via an open collector output 157 and a capacitor 165 arranged between this and the line 142. Furthermore, after opening the door of the locker, it can be determined with the transmitter 80 that the door is open, whereupon the voltage drop in line 142 to 0 volts in accordance with the clock pulse 149, that is to say without change compared to the normal clock pulse.

With such a unit of relatively simple construction, it is therefore possible to supply a multitude of specialist computers with energy and information without high circuit complexity, in particular with a low outlay on lines. Through the additional interposition of capacitor 165 between the microprocessor 159 and the line 142 it is ensured that even if the specialist computer 133 fails, the further specialist computers 145, 146 and 147 are not blocked and the operation of the system can be maintained.

A further block diagram of a specialist computer 146 is shown in FIG. 31. To transmit the information from the line 142 to the specialist computer 146, inductive loops 166, 167 are assigned to one another, as has already been shown, for example, using the exemplary embodiment in FIGS. 9 to 11. Lines 69 lead from the inductive loop 167 to the specialist computer 146. A filter element 160, for example a rectifier, is provided for the energy supply of a microprocessor 159, followed by a voltage regulator 161. Parallel to a connecting line between the voltage regulator 161 and the

Microprocessor 159, an energy store 168 can be provided. This is preferably formed by a battery. The microprocessor has a clock control element 169 with which the internal computing processes are controlled. To supply the microprocessor 159 with information, the lines 69 are connected to a receiver 170 and a conversion component 171, which in turn is connected to the microprocessor 159. An output of the microprocessor 159 is connected to a conversion component 172 and a transmitter 173.

Furthermore, as schematically shown, a coding unit 174 can be connected to the microprocessor 159, with which it is possible to enter or program the faci number.

Furthermore, the microprocessor 159 is connected to a transducer 61, for example a capacitive sensor, which is connected to the microprocessor 159 via an evaluation element 175 and an oscillator 176. In addition, it is also possible to connect a ring line 177 to the microprocessor 159 as vandalism protection. The sensors 60 and 80 can then be used to determine whether the

Bolt open or closed and the door of locker 2 is closed or open. Via a switching element 178, for example an open collector output, a drive 144 or 78 for actuating a diaphragm 74 can be provided with a recess 77, so that a keyhole 21 is entered or closed with a key f for operation.

32 shows a lock 16 fastened on the door 18 of a locker 2 and an additional lock 17. The door 18 is fastened, as has already been explained with reference to the preceding figures, for example on a armored wall 19. The lock 16 has a locking bolt 24 with which the door 18 can be locked with respect to the armored wall 19 . The originally provided additional lock 17, which serves as a bank lock in a mechanical two-lock system, has a locking bolt 179, which in the present case is now used to fix an additional lock 26 in position on the door 18. By turning a key 22 of the additional lock 17, the locking bolt 179 can be withdrawn and thus released into a holding bracket 180, with which the additional lock 26 is permanently connected. This makes it possible, for example, in the event of a defect, to replace the additional lock 26 without the locker holder having to be present. A guide pin 181 is used to fix the additional lock 26.

The additional lock 26, which now enables a remote-controlled release of the locker 2, comprises a locking pin 27 which is pressed away from the locking bolt 24 by a spring 182. If the locker customer has used the locker 2, he presses the locking pin 27 against the action of the spring 182 into the position drawn in full lines, in which it is fixed by a locking pin 183 which is also loaded in such a way that the end facing the locking bolt 24 in this engages and makes an adjustment movement of the same impossible. If the locker customer then wants to use his locker again, the locking pin 27 is pulled back into the position shown in dashed lines by pulling back the locking pin 183, for example via a drive 184 formed by an electromagnet, whereupon the locking pin 183 also the dashed Assumes position and the locking bolt 24 with the lock 16 can be moved. As a result of this design, when retrofitting lockers which are equipped with two mechanical locks, the bank lock which is no longer required by the remote control can also be used as emergency actuation for the remote-operated bank lock.
