Abstract

PCT No. PCT/AT89/00045 Sec. 371 Date Jan. 4, 1991 Sec. 102(e) Date Jan. 4, 1991 PCT Filed May 5, 1989 PCT Pub. No. WO89/11016 PCT Pub. Date Nov. 16, 1989.A locker unit comprises a plurality of lockers provided with doors equipped with a locking device. The locking device consists of a mechanical lock and an auxiliary lock having an electric drive for said device. The locking device comprises a rest position which blocks the access to the mechanical lock and/or its movement, and an opening position which frees said access and/or said movement.

Description

The invention relates to a locker system, as described in the preambles of the independent claims 1 and 2.

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 widely used in banks to enable bank customers to store valuables without the bank's control. To achieve security against unauthorized opening of a locker, these doors are usually equipped 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, banks also tried to automate access to such locker systems, not least because of high personnel costs.

Locker systems are therefore known in which one of the two locks in the door, namely the bank lock, can be released via a remote control device by a bank official who has his workplace outside the locker system. Such a lock is known for example from EP-OS 0 096 400. The disadvantage of this solution is that a mechanical lock with two independently actuatable locking bolts is necessary and must therefore be arranged in the interior of the locker. Additional security switches ensure that if the bank clerk unauthorizedly releases the bank lock after a very short time, this means that a customer's later attempt to enter a locker with a false key also fails. 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. The disadvantage of such locker systems is that either the personnel expenditure 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 doors in the locker system would have to be replaced and separate wiring installed. The effort for this is relatively high and there is also a major problem that it is not always possible to call all customers on a certain day to outsource the valuables stored in the lockers, so that the conversion can be carried out.

The present invention is therefore based on the object to provide a locker system of the type mentioned, in which, in particular, existing locker systems can be equipped in a simple manner with mechanically actuated locks in such a way that the so-called bank lock can be operated remotely without requiring a high energy expenditure . In addition, existing locker systems should be able to be converted without the doors having to be replaced and a complex wiring network having to be installed.

This object of the invention is achieved by the features of the characterizing parts of the independent claims 1 and 2. As a result, in the solution according to claim 1, it is now advantageously achieved that access to the mechanically actuable device is provided via the additional lock Customer lock or its operation is denied. This measure, which appears to be relatively simple, ensures that the energy expenditure for actuating 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.

A design according to claim 2 is also advantageous, as a result of which the additional lock can be attached to doors with mechanical locks without an additional structure inside and thus without narrowing the interior of the lockers and the energy expenditure for actuating the electric drive can be kept low. Furthermore, it is also possible for the additional lock to be mounted in a simple manner 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.

According to an advantageous development, as described in claim 3, central monitoring and actuation of the lockers and thus increased security against unauthorized opening of such lockers is achieved.

An embodiment according to claim 4 is advantageous, since as a result no mechanical processing of the door of the locker is necessary.

A further advantageous embodiment is described in claim 5, since the second mechanical lock can thereby be used to fasten the additional lock according to the invention.

An embodiment according to claim 6 is advantageous, since additional mechanical security can be achieved with minimal effort, which can nevertheless be easily adjusted from the locked position to the unlocked position using a drive that requires only a small amount of energy.

Furthermore, an embodiment according to claim 7 is possible, which makes it easy for the locker user to engage the second security, namely the bank security, after the manipulation has ended by pushing in the locking bolt in the manner of a push button.

Furthermore, an advantageous development according to claim 8 is possible, whereby the power required to unlock this additional mechanical lock is limited to the retraction of a locking pin and is therefore not remotely controllable, so that manual operation can be easily replaced.

A further development according to claim 9 is advantageous, since it enables the key previously used for the mechanical customer lock to be used further.

In addition, a further advantageous embodiment according to claim 10 is possible. This embodiment is characterized in particular by the fact that only the energy required to adjust the aperture has to be applied, which, with a corresponding design, for example by a central lock or by a slit lock, corresponding to the design in a camera, only in a correspondingly more solid design, the additional bank lock can represent.

A further development according to claim 11 is advantageous, since the effort for the additional securing of the doors of the lockers, in particular when retrofitting locker systems which have doors with two locks, is thereby low.

However, training according to claim 12 is also advantageous, as a result of which a simple mechanization of the activity previously carried out by a bank official can take place.

Furthermore, an advantageous further development according to claim 13 is possible. The sensors enable the determination of the respective Lock state and can also be used to increase security against unauthorized opening of the lockers, whereby in addition to the simpler and cheaper operation of the locker system, the security standard of such a locker system can be increased at the same time.

An embodiment according to claim 14 is advantageous, since it monitors the position of the diaphragm both for monitoring whether the opening of the bank lock has been authorized or not, and for monitoring the correct function of the bank lock after a conscious opening by an operator of the bank can.

Furthermore, an advantageous embodiment according to claim 15 is possible. The arrangement of a transmitter makes it possible in a simple manner to monitor the position of the additional lock relative to the door, so that adequate security against unauthorized removal of the additional lock forming the bank lock can be achieved even without complex mechanical fastening devices.

Furthermore, an advantageous further development according to claim 16 is possible. As a result, the expenditure for energy supply and message transmission in such a locker system can be reduced.

An embodiment according to claim 17 is advantageous, since the necessary energy and the control signals for a large number of locks can be transmitted with only a single wire or line.

An advantageous development describes claim 18, whereby the installation of additional lines in existing locker systems can be saved.

Here, an advantageous embodiment according to claim 19 is possible, whereby 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, a further development is possible according to claim 20, whereby a connection of several additional locks of a locker system to an entire network is facilitated.

An advantageous development describes claim 21, whereby a seamless connection between the adjoining light guide parts can be made even when opening a door 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.

An embodiment according to claim 22 is advantageous, since this allows transmission in the joint area of the door between the door and the body.

An advantageous embodiment is described in patent claim 23, whereby a perfect connection to the energy and message supply system is ensured both when the door is open and when it is closed.

An advantageous development describes claim 24, whereby the state of the door, whether closed or open, can be displayed immediately via the interruption of the communication link, after an energy and message supply is only necessary in the closed state of the door anyway, so that the door when interrupted can only be opened or opened without permission. However, it can be determined on the basis of the release by the bank official whether the opening took place correctly or not.

However, an embodiment according to claim 25 is also advantageous, since this completely eliminates the need to manufacture conductor tracks in the area of the body or the lockers, and if a corresponding energy storage unit is used in the additional lock, brief interruptions in energy and message transmission by a customer are also eliminated cannot interfere with the overall function of the additional lock.

According to a further advantageous embodiment according to claim 26, it is provided that this enables simple, contact-free transmission of the energy and the information.

Another development describes claim 27, whereby the supply of the additional locks arranged on the individual doors can be carried out from a central point, but this supply is not disturbed by the opening of individual doors in the locker system.

However, an embodiment according to claim 28 is also advantageous, since the light source already present in such systems can be used for energy and message transmission, and it is a relatively inconspicuous and not immediately visible to the customer supply unit, which is also a small one Retrofitting of such locker systems required.

A further development according to claim 29 is advantageous, since different frequencies in the light spectrum can be used simultaneously for the transmission of messages or energy and a further medium is not required for this task.

An embodiment according to claim 30 is also advantageous, since after the additional lock has been removed, the second lock can be used as an emergency actuation for the bank.

However, an embodiment according to claim 31 is also possible, since the control-related effort for managing the lockers, which are provided with retrofitted additional locks, can thereby be kept low.

A further development according to claim 32 is advantageous, since the wiring effort in the area of the locker system can thereby be reduced to a minimum.

Finally, however, is an education according to claim 33 of Advantage, whereby the additional locks can not only accommodate the security function for the bank lock, but at the same time also the necessary facilities and systems for energy supply and message transmission.

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

In Figure 1, 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, if appropriate, 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 a further card reader 9 are also connected to this central control unit 11 in the area of the access door 5. The shooting range 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 now wants to visit his locker, he must identify himself, for example at 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 prepared by the clerk Completed and signed the form. The counter clerk then has the option of entering the respective customer number or the name of the user via the screen workstation, whereupon the corresponding signature or personal data, for example a photo or the like, is 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 official can release the respective locker 2 for access by the user via the screen workstation and the central control unit 11. The user then moves them into the area of the access door 5, where he or she may have access to the vault 3 after having checked the access authorization again using the card reader 9. In the vault 3, he can now use his key to open the locker 2 belonging to him, whose additional lock 17, shown schematically by a box, has been unlocked via the central control unit 11 or from the 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 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 via lines 33 to a control device 34. Dar control device 34 are assigned sensors 35 and 36, with which the position of the additional lock 26 relative to the door 18 can be constantly monitored or with which the ambient temperatures or vibrations can be determined in order to determine whether an unauthorized person is trying to use force Provide access to a locker 2. These sensors 35 and 36 are preferably attached to a circuit board 37 or a computer board supporting the control device 34. The computer plate can of course also be formed by a potted module that is provided with standardized plug devices. It is connected via a conversion component 38, for example to a solar cell arrangement 39, which in turn forms part of a communication system 40 - FIG. 3.

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, can be superimposed on these light rays 43. This superimposition can take place both for signal transmission from the radiators 41 to the conversion component 38 and in the opposite direction. The signal transmission 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 an indication 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 one 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 good signal reception of the signals 44 is ensured. Of course, it is also possible for the solar cells 45, as shown in FIG. 3, to be arranged parallel to the doors or for the angle 46 to be 90 degrees.

5 shows another embodiment variant for an additional lock 26. As described with reference to FIG. 2, the door 18 is rotatably mounted on armored walls 19 via hinges 20. On the side of the door 18 facing away from the operator, a mechanical lock 16 is arranged, which is firmly connected to the door 18. 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 can - as indicated schematically - contain another lock 47. If, in order to facilitate the operation according to the invention, this further lock 47 is to be replaced by a remote control, a housing 48 of the additional lock 26 is built in front of the keyhole 21 of the further lock 47 contained in the mechanical lock 16, 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. The additional lock 26 includes 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 of the opening 53. A height of the opening 53 essentially corresponds to this distance of the most distant points of the locking lugs 52 or is slightly larger. Dar the locking lugs 52 bearing rotary latch is also connected to an actuating button 54 projecting over the housing 48, so that the rotary latch 51 can be operated from outside the locker 2. A locking member 55 is also connected in a rotationally fixed manner to the locking bolt 51, as is indicated schematically by welds between the locking bolt 51 and the locking member 55, which can be formed by a disk.

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 biasing force acting in the closed position, indicated schematically by an arrow, is exerted on the rotary latch 51. The spring device 56 therefore tries to keep the locking lugs 52 always in their position corresponding to the closed position and shown in full lines in FIG. In order to allow actuation of the rotary latch 51 only when an authorized user wants to open the door 18 of his locker 2, a locking device 57 is provided. In the example shown in FIG. 6, the latter orders a drive 58, for example a piezo drive, and a latch 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. If an unauthorized user now tries to turn the locking bar 51 in the opening direction with the actuating button 54, this is not possible, since a rotation of the disk-shaped locking member 55 is prevented by the bar 59. On the other hand, if the bank has access to Locker 2 released, current is supplied to the bolt 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 circumferential area of the disk-shaped locking member 55, and the rotary bolt 51 can now be adjusted against the biasing 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 has 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 light beams 43 to perform, as has been described with reference to Figures 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 without authorization 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 sensor 60 monitors the position of a control pin 63 on the disk-shaped locking member 55. If the control pin 63 is rotated from the position shown, the sensor 60, which can be formed, for example, by an electromagnetic proximity switch, activates and indicates a corresponding control signal the control device 34. The transmitter 62 can be designed similarly to the transmitter 60, 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 in the event of impermissible vibrations, such as would occur when a locker was opened or pried open, 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, 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 instead of the piezo drive.

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 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 pulled into the electromagnet against the action of the spring 66 and the movement of the rotary latch 51 is released. It is thus possible to move the rotary latch 51 - as described with reference to FIGS. 5 and 6 - into an open position against the action of the spring device 56.

Another embodiment of an additional lock 26 is shown in FIGS. In this embodiment, 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 also be retrofitted can be equipped with a normal double lock for a so-called "bank key" and a "customer 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 attaching the additional lock 26 with his previously used key through the additional lock 26. The attachment of the additional lock 26 can be achieved on the door 18 by screwing, gluing or welding.

9 and 10, the design and arrangement of the conductor tracks 67 and 68 is now 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 lacquer. This film 71 can be glued directly onto the side of the door 18 facing the armored wall 19 and can be contacted with the lines 69 passing through the door 18. But it is also possible that the conductor strip - as indicated schematically by dashed lines in the area of the additional lock - is wound around the door 18, so that drilling through the door 18 can be avoided and the control device 34 directly on the outside of the door 18 with the Conductor 67 can be contacted.

In order to now absorb the coil formed by the conductor track 67 with energy by induction, the conductor track 68 also forms a coil on the armored wall 19, which coil also has lines 72, which can also be formed by conductor tracks applied to self-adhesive films or by self-adhesive conductor films an energy system. By appropriately applying alternating current to the coil formed by the conductor track 68, a voltage is induced in the conductor track 67 and the coil formed therefrom, which voltage can be used to supply energy to the additional lock 26. By appropriate modulation of the AC voltage, information or Control signals are transmitted from a central control unit to the control device 34.

11 shows the structure of the additional lock 26 in detail. 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 rotatably supported 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 arranged congruently with the keyhole 21. On the locking member 73 there is also 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 shown of the locking member 73 is assigned to the transmitter 60, with which the position of the diaphragm 74 can be monitored. 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 manufactured 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 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 transmitter 80 can also be arranged in the region of the recess 77. Through the interaction of the transducers 60 and 80, it is then possible to precisely monitor the respective position of the aperture 74 by signaling the closed or the locked position of the aperture 74 when the output of the transducer 80 is occupied, while when the aperture 74 is in the open position, the Output of the transmitter 60 is occupied with 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 at the same time, 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 so that after closing the lock 16 and removing the key from the keyhole 21, the keyhole 21 can be closed automatically 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 via hinges 20 to the armored walls 19 or in the armored frame. On the inside of the locker 2 side of the door 18, a mechanical lock 16 is arranged, which can be locked via a key which 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 formed 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 polarity of 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 the conductor tracks 86, 87 to the doors 18 can take place in such a way that the individual layers are successively sprayed or evaporated onto the doors, or it is also possible to form the insulating layer 88 and the conductor track 86 as a preferably self-adhesive film strip, which is then only applied 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. These contact devices can have spring-loaded contacts 92, for example, 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 track is coupled to an energy store 93 in the area of the additional lock 26. 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, conductor tracks 94 are arranged on the body or the struts or armored walls 19, which can be arranged on the armored wall 19, for example, in the region of the doors 18 with the interposition of an elastically deformable carrier layer 95. Through this parallel connection, the interconnect 94 arranged on the armored wall and the interconnect 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, 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 of the doors 18 can take place from any side, or it is also possible to do so by means of a corresponding control logic in the central control unit 11 prevent, for example, in a row of lockers 2 arranged one below the other, more than one locker 2 is 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 be arranged parallel to one another on this insulating layer 88. This makes it possible to separate the signal lines from the power supply lines or to set up different circuits via which the individual doors are supplied, for example alternately.

Another type of communication system 85 is shown in FIG Supply of the lockers 2 of a locker system 1 shown on doors 18 from one another or next to one another is shown. Additional locks 26 are arranged on the doors 18, which can be designed, for example, in accordance with the above-described embodiments. The communication system 85 is now designed wirelessly for the energy supply of the individual additional locks 26. The transmission of energy and information or messages between the additional locks 26 takes place 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 transmit different signal sequences and also 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 correspondingly designed coils.

The transmission elements 101 and 102 are interconnected with the control device 34 arranged in the respective additional lock, to which a keyboard field 104 can be connected, for example. Different 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 which, for example, the locking plate 81 does not contain the keyhole 21 releases.

Another embodiment variant for the automation of an existing locker system is shown in FIGS. The existing system consists of lockers 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. In this way, almost all existing non-electronic locker systems are set up. A group of doors 18 is assigned only one common actuating device 106, which is remotely controlled from the operator station of the bank and can actuate the additional lock 17 of the locks 16. A drive 107, for example a rotary drive, is provided on the actuating device 106 to actuate the bank lock. The rotary drive is non-rotatably connected with a key 108. The drive 107 with the key 108 is connected to an infeed drive 110 in a guideway 109 which is oriented perpendicular to the door fronts of the doors 18. With this feed drive 110, the drive 107 can be inserted with the key 108 into the key hole 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, as shown in FIG. 17, to be opened during this movement, a support arm 112 of the actuating device 106 can be moved from a position close to the doors 18 , are pivoted into a position remote from this. For this purpose, the support arm 112 is arranged on pivot axes 113 of carriages 114 which can be moved in the guideways 111. For pivoting the support arm 112 about the pivot axes 113, a pivot drive 115 is provided which is coupled to one of the two pivot axes 113 so as to be rotatable.

By means of this central actuating device 106, it is now possible to automate existing locker systems 1 with a plurality of lockers 2, which are secured by two mechanical locks, so that bank personnel are no longer required to assist the customer when opening his locker 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.

19 and 20 show another embodiment of a central actuating 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 gearwheel which is arranged in a rack 119 arranged on the guideway 111 intervenes. 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. A drive 107 for the key 108, which engages in a keyhole 21 of the additional lock 26, is arranged in the working head. 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 infeed 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.

By designing the robot 117 or its height adjustment drive 121, it is possible to move the working head 120 into an area after the additional lock 26 has been locked or unlocked lower 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 assumed for opening the additional lock 26 and the working head 120 only - as indicated by an arrow 123 - into the position shown with dashed lines can be pivoted so that access to that door 18, in which the additional lock 17 has been unlocked, is free.

In Fig. 21 a part of a door 18 is shown, which is provided with two key holes 21 for a mechanical lock 16 and an additional lock 17. In order to allow 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 and can be scanned with sensors in the working head 120 or on both sides of the key 108 to allow the key 108 to be inserted properly into the keyhole 21 of the lock.

22 and 23 show the possibility of wireless energy transmission via electrical, magnetic or electromagnetic fields. This principle is of particular importance when automating existing, purely mechanical locker systems, 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 those necessary for controlling the locks Radiate signal data or receive the response signals of the additional locks. These antennas are in turn connected to the central 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 frame antenna 127 is now placed around this block of lockers, which in turn is connected to the central control unit and emits both energy and 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 a screen work station 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 linking of the screens 129, the input keyboards 130, the mass storage 131, and the log printer 12 and the issuing of the corresponding control commands to a network controller 132 takes place via the central control unit 11. To this network controller 132, each individual locker 2 has associated computer, one of which with 133 is designated, but lines 134 are connected. With the appropriate design, up to 2048 specialist computers can be connected to each network controller. The network controllers 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 storage 131 and the log 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 it, as described with reference to the preceding figures, via optical connections, for example modulated infrared light, light guides or via magnetic fields, e.g. inductively or by radio frequency, for which reference is made in particular to the representations and explanations relating to FIGS. 3, 9 and 10 and 22, 23.

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

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

The basic structure of a specialist computer module 138 is shown in FIG. Via the safe bus 135 or an optical or magnetic communication system 40 - which is indicated schematically by wavy lines - an energy converter 139 and a data transmitter and
Receiver 140, each of which forms a conversion component 38, is supplied with energy or information. 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, transducers 60, 61, 62 and 80 are connected to the specialist computer 133. The sensor 60 can be used to determine whether the lock is locked or open. With the transmitter 61 it is possible to determine whether, for example, an undesirably high or impermissibly high temperature is occurring and accordingly, for example, a violent attempt to open is taking 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 transmitter and receiver 140 or from this 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 135. 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, the specialist computer 133 reducing the voltage at intervals of one ms for about 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". The voltage curve in line 142 is shown in both figures as shown in FIG. 26. 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 based on block diagrams of the network controller 132 and the specialist computer 133 is shown, each specialist computer 133 counts clock pulses 148, with the explanation of the control method assuming that a control sequence begins at time t0, that is to say due to the rise in the voltage in line 142 from 0 volts to 15 volts the subject computer 133 assigned to the locker with the address "0", as shown in FIG. 24 with the right group of subject computers, that it is addressed. If the locker is now properly closed, which is assumed in the present case, the voltage level in line 142 is reduced to 0 volts after 0.5 ms, not only after 0.75 ms, as shown with dashed lines, by specialist computer 133 . 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 specialist computer 145, FIG. 24, is addressed. If it is now 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 thus unchanged from the clock curve shown in FIG. 26.

After the voltage in line 142 has risen again to 15 volts after the clock pulse 149, a specialist computer 146 of a third locker with the internal address "2" is thereby activated. It is assumed that the locker assigned to the specialist computer 146 is defective. Accordingly, a clock pulse 150 begins, for example, after 0.25 ms and the voltage in line 142 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 clock pulse 150, the voltage then rises again to 15 volts, whereby 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 reduced to 0.1 ms, that there is an unauthorized opening of the compartment. On the other hand, it is also possible that a specialist computer 133 or 145 or 146 or 147 only emits a signal corresponding to the open door or a clock pulse 148 or 151 in the event of an unauthorized opening, the network controller 132 being determined on the basis of an internal comparison whether 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 possible that the triggering of the clock pulse cannot be activated solely by the sensor indicating the closed or open position of the door, but also 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 takes place in that the supply voltage lying between two clock pulses 148 to 151 is only 10 volts instead of 15 volts, as is shown between the clock pulse at time t0 and the clock pulse 148 or the clock pulse 150 and the clock pulse 151 in FIG. 28.

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 from the energy source via a voltage converter via a protective resistor 153 with a reference voltage of 15 volts. To generate the clock pulses there is a clock control element 154, an opening 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 has an open collector output 157, is now driven at a distance of, for example, 1 ms, but this distance can also be smaller or larger and, for example, be 5 ms which reduces the voltage on 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 transmitted to the locker addressed between two clock pulses, the voltage can be applied via a voltage limiter 158, for example, via an opener 155, which also has an open collector output 157 a Zener diode that is set at a threshold of 10 volts, the voltage on 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. These can also be comparison elements, which are each supplied with a reference voltage via an input. Depending on the voltage present on line 142, a signal is now output to microprocessor 159 via threshold switch 162 or threshold switch 163. After the reference value at input 164 at threshold switch 162 is set to greater than 10 volts and at threshold switch 163 to greater than 5 volts, three different voltage states in line 142, namely voltage 0 volt, do not correspond to any signal at the input of threshold switches 162 and 163, 15 volts, at least the output of the threshold switch 162 is applied 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.

Corresponding to the input states defined with reference to FIGS. 26 to 28, the application of a signal to the line leading from the threshold switch 163 now means that the drive 144 may have to be applied via an amplifier 143. By retracting the latch with the drive 144, the transmitter 60 is activated and transmits the message "bank lock or latch open" to the microprocessor 159. Accordingly, with the same or with a longer response time of the drive 144, the reference voltage of 15 volts is prematurely reduced to 0 with the clock pulse 148 or 151 during the next polling cycle. This takes place again via an open collector output 157 and a capacitor 165 arranged between it 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 the line 142 to 0 volts corresponding to the clock pulse 149, that is to say without change compared to the normal clock pulse.

With such a relatively simply constructed unit, it is therefore possible to supply a large number of specialist computers with energy and information without high circuit complexity, in particular with a low expenditure 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. An energy store 168 can be provided parallel to a connecting line between the voltage regulator 161 and the microprocessor 159. 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 compartment 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 is open or closed and the door of the locker 2 is closed or open.

Via a switching element 178, e.g. 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 released or closed for operation with a key.

32 shows a lock 16 fastened to 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 wall 19. The lock 16 has a locking bolt 24 with which the door 18 can be locked with respect to the wall 19. The originally provided additional lock 17, which serves as a bank lock in a mechanical two-lock system, has a mirror 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 a retaining bracket 180, to which the additional lock 26 is permanently connected, can be released. 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. Has the locker customer used the locker 2, he presses the locking pin 27 against the action of the spring 182 in the position drawn in full lines, in which it is determined by a likewise loaded locking pin 183 such that the end facing the locking bolt 24 engages in it and makes an adjustment movement of it impossible. If the locker then wants to use his locker again, the locking pin 27 is withdrawn by withdrawing the locking pin 183, for example via a drive 184 formed by an electromagnet, into the position shown in broken lines, whereupon the locking pin 183 also has the broken line Assumes position and the locking bolt 24 can be moved with the lock 16. With this design, when retrofitting lockers that are equipped with two mechanical locks, the bank lock that is no longer required by the remote control can also be used as an emergency actuation for the remote-controlled bank lock.
