Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a locking device comprising a lock and a key, and having a locking portion that can be moved to an open position with a key.

Locking devices of this type are known and are constructed, for example, by a cylinder lock that can be locked with a flat key or by a locking device that operates with a magnetic key.

Common to all of these locking devices is that the number of locking combinations is usually quite large, but can be even larger to improve reliability. In particular with regard to locking installations with superior and inferior keys, a need arises to be able to use a large number of keys with different rights of passage within one installation. Locking installations of this type often have the disadvantage that the common key that can be used for the locks of the entire installation contains only a relatively simple code. If we are concerned with locking devices used by constantly changing users (e.g. in hotels), it is of paramount importance that a previous user can easily copy the key to allow unauthorized access to the room occupied by the next user. The aim is to guarantee that the

In many known locking devices, the number of locking combinations is increased and the key structure is also large, which is detrimental to comfort.

An object of the present invention is to provide a locking device of the type described at the beginning of the book, which does not increase the structural shape of the key even if the number of locking combinations is increased. In particular, to provide an emergency key that can open the lock in an emergency and furthermore guarantees that unauthorized locking operations cannot be easily performed in equipment where users are constantly changing. Furthermore, it is difficult to misuse the emergency key, so the introduction of this locking device in many ways must be expanded.

The above problems are solved by the present invention as follows. That is, at least one of the locking parts is magnetically actuated by a reader that detects at least one auxiliary code of this key, in addition to or instead of directly manipulating the basic code of the key corresponding to the locking part. It is based on being set in the open position by the coil. Therefore,
In principle, the locking device according to the invention can be controlled in the usual way (e.g. mechanically or by means of a permanent magnet), especially in the case of a coded magnetic card, by a key which operates a certain number of locking parts. . However, a small number of locking parts can be brought into the open position by means of a predetermined key according to the invention exclusively by means of a magnetic coil. This is done by a reading device that detects an auxiliary code.If this auxiliary code matches the lock code, the corresponding lock is opened.Therefore, according to the present invention,
The encoding of the key at that time, i.e. the basic code (for example, key notches, permanently arranged permanent magnets), provides an auxiliary encoding (auxiliary code).

Thus, further reliability is provided. This type of auxiliary code can be formed as a bar code and/or a hole pattern cut into the key and/or a magnetic code (especially a magnetic tape code) that can be detected by a TLZ read head, but without increasing the structural shape of the key. . It is advantageous to form this key into a card. However, auxiliary codes can be used in conjunction with regular key codes to significantly increase the number of coding combinations.

Additionally, the barcode can be easily changed by attaching it to the key as a pasted object.

The perforation code can be changed with additional perforations. Changes to the magnetic code can be made using additional permanent magnets, or in the case of magnetic tape.
You can change the information attached to it. Therefore, in the case of equipment where the users change constantly, the unlock code of the locking device can be changed every time the users change. In that case, it can be guaranteed that the reading device will identify the correct code each time, and that this will be carried out, for example, according to a previously written program, and that this encoding will be written each time the user changes. . In this case, the device can be configured such that the preceding writing is processed automatically by the electronics of the reader or lock, so that a cable connection to an expensive central unit can be omitted. The keys presented here are each equipped with an actual code, in which case the keys are crab-knitted.

In addition to, or instead of, the operability of the magnetic coil carried out in the reading device, according to the invention, the lock attached to the magnetic coil can be operated by means of the encoding of the key - i.e. without the aid of an auxiliary code. Can be placed in one open position. It is thus possible to provide an emergency key that can open the locking device even if the reading device or similar device is defective.

This type of failure can also occur, for example, due to a malfunction or a failure of the power supply. Depending on the type of auxiliary code, the reading device can be configured as an optical reading device or as a reading device equipped with an inductive magnetic head.

Another feature of the present invention is the case.

Inside this case there is a slider that can be moved by a magnetic key in case of the correct code.

This slider places the lock in the open position in the travel position.

In that case, it is advantageous if the magnetic key is formed by a card equipped with a magnetic code with a barcode on at least one surface.

In a special embodiment, the slider has a bearing recess on its support surface, which rests on a hole plate fixed to the housing, into which a locking part formed by a magnetic pin can be slid, the holes in this hole plate being , the slider fits into the support recess at its standard position. The basic structure of this device is disclosed in European Patent No. 24242.

In this case, the locking device has a magnetic card slot whose surface becomes parallel to the hole plate when inserted.

When a magnetic card is inserted, the clasp is removed.

Before this retaining plate is inserted, it pulls the magnetic pin in the bearing recess, but as a result of this removal, the retaining plate partially enters the bearing recess, and a part of the cross section of the retaining plate is inserted into the six-piece temporary fixed to the case. change position. Therefore, in this state, the slider cannot be placed in the supporting position. When a magnetic card is inserted, the magnetic pins are pushed back into the bearing recess with the magnetic poles of the card and the corresponding magnetic pin facing each other in the case of the correct card code. Thus, the fitting to the hole plate is released. The magnetic card thus allows the slider to be placed in the bearing position and the lock to be placed in the open position.

According to one embodiment of the invention, some of the magnetic pins form the basic cord by position, number and magnetic pole, and other parts constitute the auxiliary cord.

In this case, it is advantageous if at least seven of the bearing recesses are arranged in a support of a magnet pin, which is rotatably supported on the slide and fixed in a fixed rotational position. By moving the magnetic pin support, the combination of cords can be further changed.

For the simple construction of this locking device and for the use of at least one of the locking parts for the basic cord and/or the auxiliary cord, at least one of the bearing recesses is surrounded by a magnetic coil.

Furthermore, the object of the invention is solved by a locking device consisting of a lock and a key and having - cases. The case has a slider which can be moved by means of a key to bring the lock into the open position, and when this slider is in its bearing position it brings the lock into the open position. In this case, a reader is installed to detect the auxiliary code of the key. This reading device controls at least one preliminary lock that frees the slider.

In this case, it is advantageous if the pre-locking part is formed by an electromagnetically movable locking pin.

The locking device according to the invention is provided with a lower base case which can be introduced into the case of the lock, which substantially accommodates the reading device and possibly the pre-locking part, if an existing lock is used. , is particularly easy to implement. Therefore, the lock case and case of this lock are fixed on the lower base case,
Transferring already known locks to the object according to the invention by simple means, when it can only be ensured that the reading device with the reading sensor, which is essentially present in this lower base case, creates a passage for the key. Can be done. The pre-locking part cooperating with the slider can be introduced into the lock case and/or the lower base case in a suitable manner. This can be achieved, for example, by creating a receiving passage into the slider into which the locking part enters.

In order to make the locking device according to the invention reliable against operation, at least one bearing recess is provided which is arranged on the side of the slider opposite to the support surface of the slider. The magnetic pin of this recess cooperates with a stop on the case side in the closed position.

This measure prevents unauthorized opening of the lock as a result of striking the lock case with, for example, a hammer or similar object and causing the magnetic pin of the lock to dislodge from the hole in the hole plate.

Since this kind of displacement usually occurs at the same time and in the same direction in all magnetic pins when the lock is struck, the additional magnetic pins are placed in a reference position on the slider side opposite the slider support surface. It partially protrudes from the attached bearing recess and reaches the rear latching part with a stopper on the case side. In this way, displacements of the slider are excluded even if other magnet pins are moved out of their closed position by impact action.

As keys, key cards can be prepared that are subdivided into regular key cards and emergency key cards. The regular key card is a low-order card, and in this card, the encoded position attached to the electromagnetically operated locking part is formed as a non-magnetic area. With this type of card, a special lock surrounded by a magnetic coil cannot be operated using a basic code. In any case, this operation is carried out by means of an auxiliary code which is detected by a reading device and which, by excitation of a magnetic coil, turns the corresponding lock into the open position.

In addition to this type of lower-level regular key cards, there are higher-level emergency key cards that are given only to persons with special authority.

This emergency key card has a magnetic field in the encoded position assigned to the electromagnetically operated lock. Therefore,
When this emergency key is inserted into the lock, the lock part, which can normally be moved by exciting a magnetic coil, is brought into an open position by the magnetic field. The magnetic field thus replaces the excitation of the magnetic coil, for example if excitation of the magnetic coil is not possible due to technical defects or failure of the power supply.

The locking device according to the invention can be installed in particular in installations, such as baths, reading rooms, hotels, etc., where the use of the locking device in closed areas and/or privileged access areas or similar locations is subject to unsupervised control. In such a case, the locking device consists of a number of locks and an individual key card associated with each user, the locks and key cards being formed according to the above description. In this case, according to the present invention, the lower lock to be cut off has the basic code of the card, and the higher lock to have cut off has the auxiliary code or a combination of the basic code and the auxiliary code. Subordinate locks can be introduced, for example, in transfers. However, in order to enter the authorized access area, it is necessary to close it using an auxiliary code or a combination of basic and auxiliary codes. The same applies to the corresponding locks in the exit area of the access area, so that the control of access to this area is more secure than the use of transfers or similar objects.

Furthermore, the operation of the upper lock is displayed on the detection unit. This detection unit mainly detects the number of times each lock has been tightened and/or the time at which each lock has been tightened. By recording such data, it is possible to manage the time users spend in areas where they can enter and exit. This is necessary, for example, when using a swimming pool where there are time constraints. Furthermore, this sensing capability can provide a variety of services. Thus, for example, with the aid of the device according to the invention an automatic device for making soft drinks can be operated for the provision of soft drinks. In contrast, the card is inserted into an automatic soft drink machine and the soft drink is dispensed. In this case, since the automatic soft drink device is equipped with a superordinate lock, it will notify the detection unit that the soft drink has been taken out. Upon leaving this access area, present the user with an invoice for the services requested, e.g.
The billed amount will be displayed on the display. In this case, the creation of the bill takes place on the display unit by inserting the card. Only when the user has deposited the corresponding amount into the display unit can he leave the entry area by means of a corresponding blocking mechanism operated by the lock. This kind of treatment is not limited to the provision of soft drinks, but can obviously also be used for other services, such as the use of hair dryers, solar lighting rooms, parasol rentals, etc. .

Furthermore, according to another configuration of the present invention, when the user changes, the auxiliary code can be changed if the basic code is the same. Therefore, it is impossible for a previous user with a fully defined supplementary code to leave an unpaid bill for a later user. This is because the next user has received another new supplementary code.

This arrangement can also be done as follows. That is, before a user can use this locking device, it is necessary for the user to pay a certain amount of money in advance at the entrance of the accessible area. If a certain service is requested during the period of the person's stay, the amount corresponding to the service can be deducted from the above amount each time.

If you leave this accessible area, you will be required to pay the unclaimed amount or pay the balance.

Since the entire equipment can be operated automatically by introducing automatic equipment, there is no need for a storage area where personnel are stationed.

Other configurations of the invention provide additional functionality. In the case of the locking device described above, the emergency key allows the lock to be shut off unexpectedly, even in non-emergency situations. This emergency situation occurs, for example, whenever the lock's electronic circuitry does not work - for example due to a power supply failure. The use of emergency keys is provided for in these exceptional cases. In other words, this means that if the locking device is to function, the lock should be closed with a regular key, but if the electronic circuit fails, a purely mechanical, permanent magnetic locking system should be used. You need to install a key for

On the other hand, a locking device consisting of a lock and a key has a case. This case has a slider that can be moved by a key to bring the lock into the open position. The slider moves the lock into the unlocked position. In that case, the key has a basic code in the form of a magnetic code, which moves the lock part based on magnetic forces. Furthermore, this locking device includes a reading device that detects the auxiliary code of the key and electromagnetically operates at least one preliminary locking part;
Especially in the case of installed electronic circuits that have lost their functionality, there is an emergency key that is used, and this emergency key includes a coded position attached to the electromagnetically operated locking part in addition to the basic magnetic code. There is a magnetic zone for relocating the lock. In this case, the sensor of the electronic circuit that responds when the slider is moved to a new position is provided with a monitoring circuit that checks its function. This monitoring circuit indicates that the installed electronic circuit is functioning.
When an emergency key is used, a signal indicating the current driving state is output when the sensor responds.

The sensor according to the invention makes it possible to monitor the operating state of the locking device. Even if the installed electronic circuit is functioning,
A signal is output when the slider position can be changed using the emergency key. This monitoring circuit is equipped with an electronic circuit that receives sensor signals based on the slider's movement position, and in that case provides additional information that the slider's displacement was changed using the emergency key. As long as it is confirmed that the signal has been transmitted to the installed electronic circuit, the signal is outputted.

The monitoring circuit recognizes that the emergency key has been inserted based on the fact that a sensor signal indicating movement of the slider has arrived, even if the reader has not detected the auxiliary code. The monitoring circuit is therefore also coupled to the reading device. As long as there is a failure of the installation electronics, for example a failure of the power supply or a depletion of the battery, the transfer of the lock will occur on the one hand via the magnetic force of the basic code formed as a magnetic code and on the other hand via the magnetic force of the emergency key. This is done through the magnetic action of the zone. This magnetic zone is located at the encoded position belonging to the electromagnetically operated lock, so that the pin transfer of the corresponding lock occurs without introducing an electromagnet.

In the case of such an emergency key, it is obvious that the monitoring circuit is not functioning, so no signal is output from this circuit.

According to the invention, since a legal emergency key is used that does not require any special display, it is required that no signal be output. In this way, it is ensured that the advantages of this locking device are not confused by the fact that, for example, on the basis of convenience, an exclusively emergency key is introduced instead of a key with a basic code and an auxiliary code. be done. Based on the signal output of the monitoring circuit, abuse of the emergency key can be confirmed and prevented by appropriate measures.

According to another development of the invention, the signal is an acoustic warning signal. Therefore, in any case, if the locking equipment is misused, it will give an acoustic signal so that it will not remain undetected.

In addition to or instead of this acoustic warning signal, an auxiliary closing of the lock of the locking device takes place when the signal occurs. Therefore, if the emergency key is inserted maliciously, the auxiliary closure provided by the locking device will prevent the opening of the object secured by the locking device.

Only the key provided for the individual operating situation has an opening function, and even without locking or the like, the auxiliary closure of the locking device is still in the blocking position.

According to another embodiment of the invention, good management performance results when the appearing signals are written into the memory of the installed electronic circuit. By querying the memory, you can determine when the exploited work
You can later check which key was used to make the change. The above is possible because in addition to storing signals, other data can also be detected. That is, for example, the code of the key used again indicating the predetermined person, the date and time of use of the key, etc.

Since an auxiliary code can be provided in addition to the basic code, the number of locking combinations is greatly increased. A very reliable device is therefore provided. However, the reliability and range of installation of this equipment can be specifically adjusted to individual installation conditions by means of other features of the invention.
It will be further expanded.

On the other hand, a device consisting of a lock and a key has a case and a reader for detecting the auxiliary code of the key.

Inside said case there is a slider which can be moved by means of a key to bring the lock into the open position. This slider places the key in the open position in the travel position. In that case, the key has a basic code formed as a magnetic code. This basic code moves the lock using magnetic force. The reading device has a special key with a basic code and a command code for magnetically operating at least one auxiliary lock and programming the electronic circuit of the lock.

In that case, the reading device detects the command code and the use of a special key, in addition to outputting the command, shifts all locks to unlock, including the auxiliary locks. At the same time, actuation of the sensor responsive to the movement of the slider writes program instructions into the memory of the lock's electronics for the first time.

This arrangement has a sensor that responds to the position of the slider movement, just as in the previous variant, but its programmability allows the locking device to be introduced into special fields. Depending on the preprocessed program, special functions can be realized.

The special key program can be communicated via a special code attached to this special key instead of or in addition to the "regular/auxiliary code". The base code of the special key matches the regular key. The reason is that even when using this special key, it must be guaranteed that the permanent magnet-actuated lock will be in the unlocked position.

Two special codes perform on the one hand the transfer of the auxiliary lock into the open position and on the other hand the programming of the command. Alternatively, the entire locking section, including the auxiliary locking section,
Operated with a permanent magnet, the special key can be configured with a command code, so that this corresponds to the function of the emergency key, and the programming is carried out via a special code detected by the reading device. In particular, the following programming is possible:

"Permission": When the command key is inserted, for example, a regular 'ax. As long as y and Z are inserted into the lock sequentially within a certain time, the locking device can be operated by the authorized keys x, y, and 2. However, this programming can also be configured such that, for example, two keys need to be used in sequence in order to be able to bring the lock into the open position. The introduction of two keys is used to open a door, for example in a bank, which has double key security. That is, different people need different keys to open the door.

"Release": This programming is performed in the same way by manipulating a command key (a special key), but is used, for example, when a person loses his or her regular key X. This "cancellation" of the function cancels the programming to accept the code of the regular key x for the opening function. Therefore, it is no longer possible to lock the door with this regular key X. Furthermore,
After using a special key to "unlock" programming,
The auxiliary key is inserted into the lock, and this action replaces the lock's electronic circuit with the auxiliary key's code. This means that the auxiliary key now has a locking function in place of the lost regular key X.

"Reset": This mode of operation can also be programmed with a special key, but cancels the programmed input. New programming of this locking device is therefore possible.

According to another development of the invention, the auxiliary code and/or the instruction code is constituted by a pattern of holes through which the key can be passed, which can be detected by an optical reader. However, as an alternative, said code can also be a magnetic barcode that is sampled by an inductive read head of a reading device. In another variant, said code can be formed as a barcode that can be read with an optical reader.

It is advantageous if the key, regular key and special key are each formed by a card.

In a special embodiment, the slider has a bearing recess in the support surface, which rests on a perforated plate fixed to the housing.

The locking portion formed by the magnetic pin enters this bearing recess by being displaced, and the hole in the hole plate fits into the bearing recess at the reference position of the slider. In this case, the locking device has an insertion opening for a key formed of a card, and when a magnetic card is inserted, the planes of the opening become parallel to each other. When a magnetic card is inserted, it pushes away the locking plate that was pulling the magnet pin that was inserted into the support recess before insertion, so this locking plate partially enters the support recess and temporarily closes the hole fixed to the case in cross section. It is moved so that it bites into it. Therefore, in this state, the slider is not at the moving position. When a magnetic card is inserted,
Only when the code of the card is correct, push the magnet pin completely back into the bearing recess by opposing the same magnetic poles of the card and the corresponding magnet pin. In this way, fitting the holes is omitted. Via the magnetic card, the slider is introduced into the bearing position and the lock is brought into the unlocked position. The previous description applies to the basic code. That is,
This code works according to permanent magnets. In the case of a regular card, an auxiliary locking part (of which there may be many) is moved by an electromagnetically operated device operated by an auxiliary cord, rather than by a dot-like magnet on the card. . As soon as the correct auxiliary code is detected by the locking device's reader, a coil disposed around the auxiliary lock is actuated to move the auxiliary lock to the open position. In the case of an emergency key card, the movement of the auxiliary locking part is not electromagnetic, but is similarly effected by excitation by a permanent magnet, as in the case of a basic code.

In a preferred embodiment of the invention, the sensor can be formed by an electrical switch. Advantageously, the switching contacts of this switch are formed by microswitches cooperating with a slider.

The invention will be explained in detail in the drawings on the basis of a number of exemplary embodiments.

According to FIG. 1, a lock 1 is integrated into a door 2 and has a lock case 3. This case is placed at the bottom 4 on a lower base case 5. The lower base case 5 is fixed to the door 2 on this case side.

The lock case 3 is equipped with a rotary knob 6. With the aid of this knob, the projection 7 or the not shown closing part can be retracted as long as the lock 1 is in the unlocked position.

The rotary knob 8 arranged on the opposite side of the door 2 is connected directly to a projection 7 or to a closing part (not shown), so that the door can also be opened from this side of the door 2. . In the case of a hotel room, there is a rotary knob 8 on the inside of the room door.
is equipped. On the other hand, on the outside (corridor side) of the door 2, there are a lock case 3, a lower base case 5, and a rotary knob 6.

From FIG. 2, it can be seen that the lock case 3 has a receptacle 9. The key 10 can be inserted into this insertion slot. The key 10 is formed by a card 11 having a magnetic code with a barcode 13 on its surface 12. The barcode 13 is attached to a sticker 14 affixed on the front surface 12 of the card 11. However, it is also possible to write the barcode 13 on the front surface 12 of the card 11 instead.

According to FIG. 3, inside the lock case 3 there is a slider 15 which is formed in the shape of a flat plate and has a hole plate 17 placed on the support surface 16 of the case. In the blocking position of the lock 1 shown in FIG. 3, the hole 18 in the hole plate 17 emerges from the support surface 16 and fits into a bearing recess 19 corresponding to said hole, which is designed as a blind hole.

A locking part 20, which is formed as a magnetic pin 21, is inserted into this bearing recess 19.

In this case, the dimensions of the bearing recess 19 are selected such that the magnet pin 21 can be displaced perpendicularly to the support surface 16. As can be seen from FIG. 3, it is not necessary to insert the magnetic pins 21 into all the bearing recesses 19. Because,
This is because the number, position, and polarity of the magnet pins 21 are determined according to each combination of open codes.

The hole plate 17 has a guide plate 22, and a locking plate 23 is disposed on this plate. The locking plate 23 is held in position by a spring 24.

The tension spring 25 has one end 26 fixed to the case side, and the other end engaged with a protrusion 28 of the slider 15. Furthermore, the slider 15 forms an inclined support surface 30 which cooperates with a control plate 31 on the slider side 29 facing the mounting surface. The control plate 31 rests on the cutout 33 of the coupling sleeve 34, which slides longitudinally with the bifurcated end 32. This sleeve is under tension in the direction of arrow 36 by a spiral compression spring 35. The rotary knob 6 is fitted into the lock case 3 together with its shaft 37,
A gear 38 is provided on top of the lock case. In this case, the teeth of gear 38 mesh with the teeth on the inside of coupling sleeve 34 . The bottom surface 39 of the lock case 3 is provided with a square corner 4 with a gear 42 at the end by means of a bearing bush 40.
1 is rotatably supported. The square corners 41 cooperate with a lever mechanism installed for pulling back the protrusion 4 or the closing mechanism.

According to FIG.
Surrounded by 3. This coil also has slider 1
Put it in the corresponding depression of 5.

A lower base case 5 is connected to the bottom surface 39 of the lock case 3. This case houses an optical reader 44 and electronic circuitry not shown in detail. Furthermore, the lower base case 5 can also accommodate a current source that supplies power to the electronic circuit and the reading device W44.

In the closed position of the lock 1 shown in FIG. 3, the gear 38 connected to the rotary knob 6 engages the mating teeth of the coupling sleeve 34, which is longitudinally displaced and supported on the gear 42 in the square corner 41. Not waiting. As long as there is no connection between the rotary knob 6 and the square corner 41, the lock 1 is in the closed position. When rotation is applied to the rotation knob 6, neither the protrusion nor the blocking portion can be operated.

FIG. 4 shows the lock 1 in the open position. This open position occurs when the card 11 is inserted into the slot 9 and the code combination of the card 11 is correct.

In this case, the card 11 is inserted between the guide plate 22 and the locking plate 23, which can be inserted very simply by following the corresponding curves 45 of these parts. Looking at FIG. 3 again, it can be seen that when the card 11 is not inserted, the magnet pin 21 is fitted into the corresponding hole 18 of the hole plate 17 and hits the guide plate 22 at the front. This position of the magnet pin 21 is brought about by a locking plate 23 which, in contrast to other components, is made of ferromagnetic material.

Furthermore, the locking plate 23 attracts the magnetic pin 21 so that the magnetic pin occupies the position described. In this position, the slider 15 does not deviate from the reference position shown in FIG. This is because the hole plate 1 fixed to the case by the magnet pin 21
7 and prevents deviation.

However, if we now look at FIG. 4, it can be seen that the magnet pin 21 has completely entered the associated bearing recess 19 and is no longer connected to the hole plate 17.

This is based on the fact that the magnetic code present on the card acts on the magnet pin 21 and pushes it back into the bearing recess 19 with identical magnetic poles facing each other. When the card 11 is inserted, the locking plate 23 bends due to the spring 24. However, after inserting the card 11, when the entire magnet pin 21 is in the open position, the slider 15 is in the position shown in FIG. 4 with the card end 46 against the slider stop 47. Thus, the inclined support 30 causes the end 32 of the operating plate 31 to move the coupling sleeve 34 in the direction opposite to the arrow 36, and the inner teeth of the coupling sleeve 34
Operate the operation plate 31 so that it engages with the . Therefore,
In this position, the rotation knob 6 is fixedly connected to the square corner 41. Therefore, the lock 1 is in the unlocked position and the protrusion 7 or the blocking part can be operated.

According to the invention, the magnet pins 21 which are not surrounded by the magnetic coil 43 are brought into the open position by the basic cord of the card 11. The magnet pin 21 surrounded by the magnetic coil 43 excites the magnetic coil 43 to reach the open position. On the other hand, the card 11 is marked with a barcode 13 as already described. This barcode is optically read by the sensor 48 when the card 11 is inserted into the insertion slot 9. The sensor 48 is
It is connected to a reading device 44 via a conductor 49 . Therefore, the read information reaches the electronic circuit. This electronic circuit compares the read code with the unlock code of the lock 1. If they match, the magnetic coils 43 are energized and the corresponding magnet pins 21 are placed in the open position of FIG.

However, instead of this, a number of magnet pins 21 can also be surrounded by corresponding magnetic coils 43.

According to another embodiment of the invention, the following provisions are made to provide an emergency key. That is, this emergency key is formed in the same way using a special card 11, but is equipped with a magnetic code at a position opposite to the magnetic pin 21 having the magnetic coil 43, and this code is attached to the magnetic pin 21. to the open position. Therefore, if the movement of the magnet pin 21 is possible without the aid of the magnetic coil 43 due to a technical defect or failure of the power supply, it can also be carried out with the aid of the emergency key described above.

According to a preferred embodiment of the key 10, the barcode 13 is composed of a periodic trace and an information trace, both traces running parallel to each other. What is done in this case is that upon insertion of the card, the corresponding sensor 48 of the reading device 44 receives the reading period for successive scanning of the information trace via the periodic trace. This system has already been disclosed in German Patent No. 2,431,497.

In order to further expand the code combination possibilities, according to FIG.
It is arranged on a magnet pin support 50 which is rotatably supported at and fixed in a fixed rotational position. This magnetic pin support 50 can be rotated through an opening in the lock case 3 with a special tool. In this way, the position of the bearing recess 19 can be changed. In this way, the reprogramming of the lock 1 can be done very quickly. Two types of magnetic pin supports 50 - as shown in FIG.
5 is advantageous.

FIG. 7 shows another embodiment of the locking device according to the invention. This device differs from the previously shown embodiments by the absence of a magnetic coil 43 on the slider 15. The following measures should be taken at that location: That is, a passage 51 is formed that exits the reader 44 and reaches the slider side 29 of the slider 15. A locking part 52 configured as a locking pin 53 is arranged in this passage. This locking pin 53 can be moved by an electromagnetic device (not shown). In that case, this locking pin is in the recess 5 at the slider end 29 of the slider 15 in the blocking position.
It's getting into 4.

FIG. 7 shows the lock in the blocking position. In this lock, on the one hand, the magnetic pin 21 enters the corresponding hole in the hole plate 17;
On the other hand, the locking pin 53 is fitted into the recess 54. Thus, the slider 15 is fixed at the reference position. When this slider 15 is moved to the moving position in which the lock 1 occupies the open position, the card 11 is inserted into the slot 9 according to FIG.
You need to insert it into the .

(Then - in the case of the correct sign - the magnet pin 21 is in the open position on the one hand and the sensor 48 on the other hand reads the correct barcode. Thus, the reading device 44 or the electronic circuit coupled to this device Locking pin 5 via electronic magnetic device
3 is moved downward so that this pin comes out of the recess 54. In this position - as already described above - the slider 15 is in the displacement position of FIG. 8, in which the rotary knob 6 is connected to the corner 41 of the square.

9 and 10, the locking pin 53 is disposed on one side of the slider 15, and the sensor 48 is disposed on the other side. However, this arrangement is not mandatory.

The closed position and release position are shown in Figures 11 and 12, respectively.
It becomes particularly clear from the figure. This also shows that the locking pin 53 is pulled in the direction of the slider 15 by the spiral compression spring 55. Furthermore, a coil 56 of an electromagnetic device for moving the locking pin can be recognized. Moreover, the slider 15, hole plate 17, and guide plate 22 are
It can also be seen that the sensor 48 has a passage for the barcode 13 of the card 11 because it is pierced by the slit recess 62 .

FIG. 13 schematically shows a cross section of the slider area of the lock l. When a shock is applied to the case 3 of the lock, the magnetic pin 21 moves and immediately enters the corresponding bearing recess 19 (see the situation in FIG. 13). At this moment, slider 15
The lock 1 can be unlocked since the position of the lock 1 can be moved by means of a tool or similar object inserted into the socket. To prevent unauthorized release of this type, a magnetic bin 58 is provided on the slider side 29 opposite the support surface 16 of the slider 15.
A bearing recess 57 into which the member slides is provided. Lock 1
By applying an impact to , all the magnet pins move simultaneously and in the same direction, so that these magnet pins 58 move in the direction of the arrow 59 just like the magnet pins 21 . In that case, the magnet pin 58 is connected to the stopper 60 on the case side.
Go into the mesh behind the opponent. Therefore, slider 1
5 is effectively suppressed from moving in the direction of arrow 61.

FIG. 14 shows the state in which the card 11 is inserted. What is clear here is that the magnetic pins 21 are completely inserted into the corresponding bearing recesses 19 by opposite parts of the same magnetic pole, while the complete insertion of the magnetic pin 58 is effected by the attractive action of the opposite magnetic poles. In the open position shown in FIG. 14, the slider 15 is in the moving position.

The subject matter of the invention provides a high degree of reliability of the system by means of an electronic system operating auxiliary to the mechanical (magnetic) which provides the blocking or releasing function by reading an optical code.

This optical code can be printed or pasted (even at one time) on the key. This type of improved lock provides a high standard of security, especially in controlled traffic areas.

Furthermore, mechanical systems can be improved by the optoelectronic solution according to the invention and the advantages mentioned in the introduction can be realized.

The key of the locking device according to the invention formed of a card has magnetic zones cooperating with the locking parts that are distributed at different positions on the surface. In this case, according to one embodiment, these zones may form a basic code. Furthermore, one or more of these zones can be used for the emergency key function described above. The auxiliary code of the key according to the invention is formed by a bar code affixed to the surface and/or by a hole passing through the card and/or by a magnetic tape attached to or embedded in the surface of the card. It is then possible for this auxiliary cord to occupy one or more of the magnetic zones. According to special embodiments, the basic cord can be part of the magnetic zone and the auxiliary cord can be constituted by another part of this magnetic zone.

These magnetic zones differ with respect to their polarity (north or south pole). It is necessary to form the magnetic pin of the locking part accordingly.

The holes that pass through the key card are distributed at various locations on the surface of the card depending on the content of the corresponding key.To detect these holes, it is necessary to This is done via suitable sensors. In this case, the reading is divided into a one-period trace and an information trace in the same way as in all other encoding formats mentioned above.

In the fifteenth embodiment, the lock 1 is equipped with a lock case 3. This case has its bottom surface placed on the lower base case 5. The lock case 3 is equipped with a rotary knob 6 which pulls back a protrusion or a blocking part (not shown) as long as it is in the open position. This embodiment corresponds in principle to the construction of the lock already described. Here, I will summarize the important points once again.

The lock case 3 is partially equipped with a receptacle 9 into which the lock 10 can be inserted as described above. The key 10 is designed as a card 11 equipped with a magnetic code, which card has a barcode 13 on its surface 12.

Inside the lock case 3, there is a support surface 16 formed in a flat plate shape.
A slider 15 with a hole plate 17 placed thereon is housed. The holes 18 in the hole plate 17 start from the support surface 16 in the blocking position of the lock 1 shown in FIG. 15 and fit into corresponding bearing recesses 19 in the slider 15, which are designed as blind holes.

The bearing recess 19 contains a locking portion 2° formed by a magnetic pin 21. In this case, the dimensions of the bearing recess 19 are chosen such that the magnet pin 21 can slide perpendicularly to the support surface 16. As is clear from FIG. 15, it is not necessary to insert the magnet pin 21 in the bearing recess 19 as well. This is because the number, position, and polarity of the magnet pins 21 are specified according to each combination of open codes. hole plate 17
Above there is a guide plate 22 on which a locking plate 23 is arranged. This locking plate 23 is held in position by a spring 24.

The tension spring 25 has one end 26 fixed to the case side, and the other end 27 fitted into a protrusion 28 of the slider 15. Furthermore, the slider 15 forms, on the slider side 29 facing the support surface, an inclined support 30 that cooperates with an operating plate 31 . This operation plate 31 has a branched end 32
It rests on a step 33 of a longitudinally movable connecting sleeve 34, which is tensioned in the direction of arrow 36 by a spiral compression spring 35. A rotary knob 6 meshes with a shaft 37 of the knob inside the lock case 3 and has a gear 38 which is prevented from rotating on the case. In this case, the teeth of the gearwheel 38 fit into the teeth on the inside of the coupling sleeve 34 .

A square corner 41 having a gear 42 at its end is rotatably supported on the bottom surface 39 of the lock case 3 by means of a bearing bush 40 . This square corner 41 cooperates with a lever mechanism installed to pull back a protrusion (not shown) or a blocking part (not shown).

According to FIG. 15, the bearing recess 19 has a corresponding slider 1
It is surrounded by a magnetic coil 43 which is fitted into the recess 5.

A lower base case 5 is connected to the bottom surface 39 of the lock case 3. This case houses an optical reading device 44 and an electronic circuit not shown in detail. Further, the lower base case 5 also houses an electronic circuit and a power source for the reading device 44. However, as an alternative, it is also possible to supply the current via a wiring network, if appropriate, to an intermediate connection between the transformer and the rectifier.

In the blocking position of the lock 1 shown in FIG. 15, the gearwheel 38 connected to the rotary knob 6 does not mesh with the corresponding mating teeth of the connecting sleeve 34. This sleeve is mounted so that it can be moved in the longitudinal direction on teeth 42 at square corners 41. As long as there is no connection between the rotary knob 6 and the square corner 41, the lock 1 occupies the blocking position. Even if the rotation knob 6 is turned, neither the protrusion nor the blocking portion can be operated.

FIG. 16 shows the lock 1 in the open position, which can be introduced when a card 11 is inserted into the slot 9 and the combination of codes on the card 11 is correct. The card 11 slides between the guide plate 22 and the locking plate 23, the insertion being made very easy by means of the corresponding curvature 45 of the locking plate. Referring again to FIG. 15, it can be seen that when the card 11 is not inserted, the magnet pins 21 fit into the corresponding holes 18 of the hole plate 17 and are fitted into the guide plate 22 at the front. This position of the magnet pin 21 is brought about, in contrast to other components, by a locking plate 23 made of ferromagnetic material. Further, the locking plate 23 pulls the magnet pins 21 and places the pins in the positions described above. At this position, the slider 15 cannot be moved from the reference position shown in FIG. This is because this movement is prevented by the magnet pin 21 being engaged with the hole plate 17 fixed to the case.

However, on the contrary, referring to FIG.
It can be seen that it no longer forms an edge for 7. This is due to the fact that the magnetic signature of the card acts on the magnet pin 21 and pushes these bottles back into the bearing recess 19 with like magnetic poles facing each other.

When the card 11 is inserted, the locking plate 23 is bent by the spring 24. However, after inserting the card, when the entire magnetic pin 21 is introduced into the open position, the card 11
With the subsequent sliding of the slider 15, the end 46 of the card can be placed against the slider stop 47 in the position shown in FIG.
1 and whose end 32 is joined by a sleeve 34 in the direction of arrow 3.
6 in the opposite direction so that the inner teeth of the coupling sleeve 34 mesh with the gear 38. Therefore, in this position, the rotary knob 6 is fixedly coupled to the corner 41 of the square. The lock 1 thus occupies an open position and the projection or closure can be operated.

In this case, the arrangement is such that the magnet pins 21 which are not surrounded by the magnetic coil 43 are brought into the open position by the force, the basic cord of the -de 11. The magnet pin 21 surrounded by the magnetic coil 43 excites the magnetic coil 43 to reach the open position. On the other hand, the card 11 has a barcode attached thereto as described in part.

This code is optically scanned by the sensor 48 when the card 11 is inserted into the slot 9.

Sensor 48 is connected to reader 44 via conductor 49 . The read information therefore reaches an electronic circuit which compares the read code with the stored opening code of the lock 1. If there is a match, the magnetic coil 43 is energized and the corresponding magnet pin 21 is placed in the open position of FIG.

According to another configuration not shown, a plurality of magnet pins 21
can also be surrounded by a corresponding magnetic coil 43.

According to another embodiment, in order to provide an emergency key, this emergency key is likewise formed by a special card 11, but - opposed to a magnet 721 equipped with a magnetic coil 43; It is equipped with a magnetic code at the position where it is located.

This symbol moves pin 21 to the open position.

Therefore, due to technical defects - e.g. failure of the power supply -
If it is not possible to move the magnet pin 21 even with the help of the magnetic coil 43, this movement can be done with the help of the emergency key described above.

In order to further improve the possibility of code combinations, as shown in FIG. 50. This magnetic pin support 50 is attached to the lock case 3 using a special tool.
can be rotated through the opening in the bearing recess 19
The position of can be changed.

This method allows the reprogramming of the lock 1 to be processed very quickly. Advantageously, a support for two magnetic pins of this type is mounted on the slider 15, as shown in FIG.

FIG. 18 corresponds to FIG. 17, but in this case the lock is in the open position.

FIG. 19 shows another embodiment of the locking device according to the invention. This device differs from the previous embodiment in that the slider 15 does not have the magnetic coil 43.

The following measures should be taken at that location. That is, a passage 51 is formed starting from the reading device 44 and reaching the slider side 29 of the slider 15. A lock 52, which can be formed as a lock pin 53, is arranged in this channel. This lock pin 53 can be moved by an electromagnetic device (not shown). In this case, this pin enters the recess 54 in the slider side 29 of the slider 15 in the blocking position.

FIG. 19 shows the lock in the blocking position. In this position, on the one hand, the magnet pin 21 enters the corresponding hole in the hole plate 17, and on the other hand, the locking part pin 53 fits into the recess 54. In this way, the slider 15 is fixed at the reference position. To introduce the slider 15 into the moving position in which the lock 1 occupies the open position, the card 11
must be inserted into the receptacle 9 according to FIG. 20, and - in the case of the correct code - on the one hand the magnetic pin 21 should be in the open position and on the other hand the sensor 48 should read the correct bar code. Therefore, the reading device 44 or the electronic circuit connected to this device can connect the lock pin 53 via the electronic device.
is moved downward so that this pin comes out of the recess 54. In this position - as already described above - the slider 15 is brought into the displacement position of FIG. 20, in which the rotary knob 6 is connected to the corner 41 of the square.

From FIGS. 21 and 22, it can be seen that the lock pin 53 is located in one side area of the slider 15, and the sensor 48 is located on the slider 15.
5. However, this arrangement is not mandatory.

As described above in FIGS. 15-22. In all embodiments, according to the invention, the slider 15 cooperates with a sensor 80.

This sensor 80 is effectively formed by an electric switch. In particular, this sensor may be formed by a microswitch 82 having contacts 83 with lever movement.

The sensor 80 is connected to the lock electronic circuitry in the lower base case 5 as previously described by a cable connection not shown. The lock electronics are not shown in the drawings for simplicity.

According to FIG. 15, the microswitch 82 is located between the end of the slider 15 pointing towards the microswitch 82 and the lever contact 83 of the microswitch 82 when the slider 15 is not moved, i.e. in the blocking position of the lock. is positioned such that there is free space at However, when the slider is brought into the travel position as shown in FIG. 16, the end of the slider 15 advances in the opposite direction to the lever contact 83, so that the microswitch 82 changes its connection state.

According to FIGS. 17 and 18, the microswitch 82
is arranged horizontally offset from the longitudinal axis of the slider,
At the slider position shown in FIG. 17, the lever contact 83 of the microswitch 82 can also be inactivated. FIG. 18 shows the bearing position of the slider 15 in which a change in the switching state of the microswitch 82 occurs, since the lever contact is active.

Instead of the magnetic coil 43, the locking portion 52 is connected to the locking portion bin 5.
19 and 20, the microswitch 82 either - as in FIGS. 15 and 16 - cooperates with the surface of the slider position, or - as in FIGS.
A microswitch 82 may be located next to one slider 15 as shown in FIGS.

The difference is that if the slider is not moving,
The microswitch occupies a switching state that is different from when the slider 15 is in the moving position.

In this invention, the microswitch 82 has the following functions.

When moving the slider 15 using a "regular key" (card 11), the microswitch 82 is operated at the position where the slider 15 is moved. This operation is recorded by installed electronics, not shown. Additionally, the installation electronics receive information via the reading device 44 that a legitimate key is being used. This key then has an auxiliary code 13 mainly formed by a barcode. As long as you insert your emergency key,
Barcodes are ignored. The reason is that the corresponding transfer of the magnetic pin 21 is carried out not by the magnetic coil 43 (but by the corresponding magnetic zone of the emergency key).Therefore, the side without the barcode is The installation electronic circuit signals that the emergency key is not inserted.In addition, the following is also provided: The installation electronic circuit can detect the authorized card in each case via a special code of the auxiliary code. Unless there is this special code in the auxiliary code, for example, in the case of an emergency key, it is registered that it is driven by the emergency key.

Then, at the slider support position shown in FIG. 16, the microswitch 82 responds, and the monitor circuit belonging to the installed electronic circuit receives and receives signals in synchronization with the installed electronic circuit. This monitor circuit also checks the functionality of the installed electronic circuits, in particular whether the power supply is available. As long as the emergency key is in use, even if the monitor circuit is informed that the installed electronic circuit is functioning, the monitor circuit outputs a signal indicating the current operating state. This signal may be an audible warning signal, but it may also cause the auxiliary cutoff of the lock to be in the blocking position so that it is impossible to open the contents of the lock. Furthermore, the generation of the signal can be written into the memory of the installed electronic circuit.

As long as the opening/closing of the lock is operated with an emergency key and the monitor circuit registers the non-functioning installed electronic circuit, no signal will be output, so that type of operating pattern will not lead to the output of a warning signal. or the auxiliary shut-off is not in the shut-off position. When listed last, it indicates the desired mode of operation.

This is because if the installation electronic circuit is interrupted, the emergency key will immediately function.

According to another embodiment of the invention, microswitch 82
In addition to, or instead of, the functions described above, the program commands 44 are used to receive program instructions detected by the reading device 44 into the memory of the installed electronics. In addition to the basic code, lock part 2 is required for programming the installation electronic circuit.
In order to move the 1, it is necessary to use a special key with a special code by magnetic action, in particular formed by a barcode.

However, instead of this barcode, card 11
A hole pattern may be provided thereon which is detected by an optical reader 44 using a sensor 48 . Furthermore, as an alternative, an inductive read head coupled to the reader 44 can be provided to scan the magnetic barcode of the card 11, which is a special code.

The circuit is configured to write a special key instruction code into the memory of the installation electronics only when the microswitch 82 responds by movement of the corresponding slider.

In this way, abuse can be eliminated. That is, programming or erasing the memory of the installed electronic circuit is only possible with a special key when the slider can be moved with this special key.

Therefore, even when this special key is inserted into the receptacle 9, it is prevented that the memory device does not receive the program of the special code of the special key. Rather, movement of the slider is first necessary in order for the corresponding memory to be permitted only when the microswitch 42 is actuated, and this presupposes a "matching" key. It is thus ensured that programming can only be carried out by a person who has the attached key - for the basic code and the auxiliary code.

Card i, which has the same command program as the special key attached to the lock, does not cause movement of the entire lock 20 and cannot lead to reprogramming of the installed electronic circuitry. That is, the "mechanical" (permanent magnet) code is first interrogated before programming.

In this case, it is not necessary to move the auxiliary lock in an electromagnetic manner by means of a bar code, but rather the auxiliary lock pin can also be moved by means of a corresponding magnetic code position on the card 11. In this case, the emergency key introduced for the reprogramming operation is seemingly important.

All novel features mentioned in the specification and shown in the drawings are essential to the invention, even if not stated in the claims.
