Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The invention relates to a device according to the generic subject of the main claim.

(Prior art) A known device of this type (West German Patent Publication No. 342
1667), for use in bathhouses, the closure element of the tape lock is provided with a magnetic cord in the area of the issuing station. This matches the corresponding magnetic code of the particular lock.0 Guests are issued with such a coded closure element at the delivery station in return for payment and go to the lockers in the bathhouse and lock the lockers with the matching magnetic code. can be operated. The customer leaving the bathhouse returns the closing element to the return device. By communicating information between the return device and the issuing station, it can be managed, for example, whether a bath customer has exceeded a time limit. If a customer does not leave the bathhouse entrance, he or she must pay an additional fee if the time is exceeded. The advantage of this solution is that the closing element is coded only at the time of its delivery and that this corresponds to a specific lock. However, in order to take into account the fact that the codes of the closing elements that are issued in large numbers are different, it is not necessary to connect a conductor from each lock to the issuing station in order to assign a different code to each lock each time. A solution proposed for the descriptive level is that the magnetic encoding of the closing element at the delivery station is carried out in accordance with a running program that is identical to the program stored in the associated lock. This solution is electronically relatively expensive. This solution cannot absolutely prevent all erroneous operations.

A problem arises, for example, if, for some sudden reason, the customer immediately leaves the bathhouse without going to the locker with the correspondingly coded closure element that he has collected at the entry station. The lock itself cannot accept advance commands encoded on the previous unused closing element.

OBJECT OF THE INVENTION The present invention provides a device of the type mentioned at the outset, in particular with electronically simplified components, which provides a high degree of security against erroneous operation and which does not impede its normal use. The task is to develop the constituent parts.

(Means for Solving the Problems) The problems of the present invention are achieved (means for solving the problems) by the constituent parts described in the claims.

EFFECTS OF THE INVENTION The device according to the invention, which is very advantageous for hotel buildings or baths, provides convenience of operation and safety of operation, despite very low electronic costs. can be obtained that is extremely high. Nevertheless, there is no need to connect the issuing station to the individual locks by wires. The lock according to the invention can be adapted to a lock usable elsewhere, for example in an embodiment according to European Patent Specification 24242. The closure element card has a magnetization range and a PIN. The PIN is in particular formed in the form of a barcode. Such solutions are dealt with in the usual way today. An additionally provided magnetic combination is used to operate the magnet-locking pin which is arranged in a corresponding local combination of the lock. A feature of the invention is that the issuance station of the closure element card, each identified by a barcode PIN, performs a fully specified magnetic combination and that the other tracks of the card are activated via the magnetic combination during use. It is rather simple to do so via a subsequent barcode PIN. The issuing station, for example a PC with a printer of the closure element card, records a bar code in connection with the implemented range of polarization inside the respective issuing station of the closure element card. This association is stored in the issuing station's memory. The return device identifies the barcode via the PIN reader and sends a signal to the erasure device of the issuance station, so that the room belonging to this magnetic combination is registered if the user of the locker has already left the bathhouse or hotel and the same magnetic Whether the combination belongs to a new closure element card with a barcode and can be issued, the closure element card itself should be immediately returned to the issuing station for use by the next customer with the same lock as possible. There's no need. The lock utilization rate per unit time is significantly increased. At the end of a certain time, for example, open the bathhouse 1. A complete return of the closure element cards collected in the return device at the end of the day may take place in the closure element card memory of the issuing station. The same closure element card can be used again with the same barcode PIN. No problem arises if someone leaves a hotel, bathhouse, etc. without using the lock. - other locking devices such as those caused by having two locking element cards for a guest to use one key and hold the other until he/she wants to use a particular room, locker, etc. No risk of destruction arises. If the closure element card is lost, the lock can no longer be used. The master key function is also realized by appropriate issuance.

According to another advantageous component of the invention, a display of closure elements that have been repeated or called up at regular time intervals and have not been returned is provided. In accordance with the proposal of the invention, a magnetic combination of locks constructed in a similar manner is disclosed, for example, in European Patent Specification 2424.
2. What changes should be made to avoid each magnetic combination that can be changed via the operating tool and the dispensing station corresponds to the non-returned closure element card. By displaying instructions, supervisors at hotels, bathhouses, etc. can further eliminate the risk of misuse by changing the magnetic combination.

Magnetic combinations of closure element cards that are not returned are dissipated over a period of time. If a locking element card is lost and it is desired to open a lock, the issuing station will have a specially authorized person come and issue an identical closing element card belonging to the corresponding lock. It can then be called up via the barcode as to when the missing closure element card was issued, and a check is made as to whether it was recorded by the return device. Control to keep time limits is done via barcodes. Upon exiting via this barcode, for example at the hotel reception or at the entrance to a bathhouse, requests for additional services, such as sunbathing, food and drink, etc., can also be made.

The object of the invention is also depicted schematically.

The front entrance of a bathhouse, etc. is represented by 100. A customer enters waiting room 200. In order to be able to use the bathhouse, guests must enter the revolving door 3.
You have to pass through the entrance formed in the shape of 00.

The revolving door is supported about a vertical axis and has mutually overlapping rotating arms 500 which prevent unauthorized persons from passing through.

Use in hotels can likewise be carried out, with the entrance and exit being at the reception.

At the entrance 300 there is a closing element card issuing stage gin. The issuing station has an operational field 700 . There, cash is received and collected.

There are specifically stacked closure element cards 800 at the issuing station 600 . These have different barcodes. The barcode can be read by a corresponding reading device at the delivery station. After inserting a coin, a particular closure element card is removed from the stack and its code is captured and applied by a magnetic device, which magnetizes the closure element card 800 and is placed under the magnetic device by the magnetic part surface MP. Locating closure element card 800″
is expressed. The electronic storage at issue station 600 stores the specific magnetic combination (local arrangement, including the field MPO side pole on card 800) belonging to each bar code on the closure element card. A card will then be issued. The user takes the card along the path indicated by the arrow and goes to the locker in locker row S shown. Onrong belongs to closed element card 80
A corresponding code is printed on the 0, which takes place during or after magnetization. The customer operates the lock 1100 using the card. He cannot operate other locks due to the mismatch of magnetic combination MP. The inner shrine for bathing is available from the exit.

He places the closing element card on the table 1800 of the return device 1700 to effect the release of the revolving door 1600 (.

This is to check whether the regular bathing time has been met or exceeded. If time is protected and no additional services are requested, the revolving gate will open. Returned cards are collected. At the same time, the reading by the PIN-retrieval device is started and an erasure command is sent to the issuance station 600, and the corresponding magnetic combination is released again and recorded as available for use on another closure element card 800 with another barcode. can be aligned.

EXAMPLES In all illustrated embodiments, the lock shown in FIGS. 1 and 2 has an elongated lock housing 1 attached to a locker door (not shown). At its one end the lock has one rotary knob 2, by means of which the lock can be pulled back as long as it is in the unlocked state.

In all magnetically actuated embodiments, the lock shown in FIGS. 1 and 2 has an elongated lock housing 1 attached to the door, not shown. At its one end, the lock housing has a rotary knob 2 by which the blank line or lock can be pulled back as long as the lock is in the locked position.

The rotary knob 2 can be connected to a push rod 3 having a rectangular cross section, and the push rod is a carrier for an inner knob (not shown) located on the door side. An empty line or lock (not shown) can be returned at any time by means of an inner knob.

In order to be able to operate the lock from outside, the lock housing has an insertion slit 4 on the end face facing the rotary knob 2.
A card-shaped key 5 can be inserted into the insertion slit. As the key 5, a card with a magnetic code of sufficient rigidity is used so that the slider 6 guided in the lock housing 1 can be moved by the card.

An inner housing 7 inserted into the lock housing 1 is used for accommodating the slider 6, and the inner housing has two guide plates 8 and 9 arranged counterbalanced to the slider 6.
has. A plate made of ferromagnetic iron is used as one guide plate 8, and the other guide plate is made of a non-magnetic material. The guide plate 8 is thicker than the adjacent guide plate 9 and is biased by a leaf spring 10 supported on the bottom 11 of the inner housing 7. Guide plate 8 before inserting key 5
．． 9 are located flat to each other. When the key 5 is inserted between the guide plates 8.9, the guide plates 8 flex elastically towards the bottom 11.

The non-magnetic guide plate 9 is supported by a stop plate made of a non-magnetizable material. Brass is used as the stop plate in the embodiment. The stop plate 12 has stop holes 13 arranged at a corresponding pitch, and the stop holes are arranged in the blind hole 1 of the slider at the starting position of the slider 6.
This is consistent with 4. A pin-shaped permanent magnet 1 is placed in a part of the blind hole.
5 is inserted, the permanent magnet is attracted by the guide plate 8 and passes through the stop hole 13. Depending on its configuration, the permanent magnet then energizes the guide plate 9 with either south or north pole. Slider 6 is therefore not displaced. The slider also has a tension spring 16 biased toward the insertion slit 4.
under the action of A tension spring 16 is connected at one end to a pin 17 of a cover 18 surrounding the slider 6 and at the other end to a pin 17 of a cover 18 surrounding the slider 6.
A control protrusion 19 protruding from the top is hung. The control projection is provided with an inclined surface 20, by means of which a leaf spring 21 fixed in the inner housing 7 at the height of the insertion slit 4 can be displaced in the direction of the arrow X when the slider 6 moves forward; The leaf spring entrains the coupling sleeve 22 and brings the rotary knob 2 into the coupling position with respect to the push rod 3, which allows the door to be opened subsequently.

However, the advance of the slider 6 is only possible after insertion of the proper key 5, which in the fully inserted position extends its edge 5'' against the entraining shoulder 23 of the slider 6 inside the lock.
Supported by In the key insertion position, the corresponding permanent magnet 15 faces the correspondingly positioned magnetized area of the key. The permanent magnet is thus repelled in the direction of the blind hole 14 and is thereby disengaged from the stop hole 13 of the stop plate 12.

For changing the magnetic closure code, the slider 6 according to the first embodiment has four interconnected rotatable carriers 2 each.
4.25.26.27, and the carrier is equipped with code conversion magnets 28.29.30.31 formed as final tightening members. On the outside, the carriers 24 to 27 are provided with teeth,
Teeth interlock with each other. A diameter-matched bore 32 is provided in the slider 6 for receiving the carrier. The carriers each having one code conversion magnet are arranged in such a way that the code conversion magnets are successively moved into or away from the position of the disturbance, respectively, by a rotational movement of the carrier. Interference part 3
3 is formed by a horizontal edge of a vertical groove 34 extending in the moving direction y of the slider 6. Since four code conversion magnets or final tightening members are provided, four such longitudinal grooves 34 are provided.
Also provided. The longitudinal groove is in the cover 18 of the internal combustion engine of the inner housing 7 which covers the slider 6. The other longitudinal grooves arranged on the inside of the lock have a greater distance from each other than the remaining freeing longitudinal grooves 34.

However, only one of each of the code conversion magnets 28 to 31 serves as a genuine code conversion magnet or a genuine final tightening member. According to FIGS. 4 and 5, this is a code conversion magnet 28. When the subsequent key 36 is not inserted, the code conversion magnet has its end facing the stop plate 12 inserted into the vertical slit 35 located in the direction of movement of the stop plate 12.

The remaining code conversion magnets 29, 30, 31 can be inserted into corresponding stop holes 13 of the stop plate 12, so that the code conversion magnets in this case assume a function similar to permanent magnets.

If the lock is attached to a hotel room door, for example, the guest has a guest key comparable to key 5. The guest key displaces the permanent magnet 15 and all the code conversion magnets 29, 30, 31 so that they are removed from the locking hole 13.

Thereby, the slider 6 moves in the direction of the arrow y while being connected to the rotary knob 2. The code conversion magnet 28 or the final tightening member is not moved. The movement movement is carried out by the vertical slit 35 of the stop plate 12.
This is possible only by

If this hot water key is not returned to the return device 1700 for a predetermined time (for example, until the evening), a command is issued to the issuing station to issue a master key for code conversion by the bath owner. This master key disengages all the permanent magnets and the code conversion magnet 28 from the stop plate 12. Therefore, the code conversion magnet 28 enters the longitudinal groove 34. When the slider is displaced by the master key 36 in the direction of the arrow y, the corresponding end of the code conversion magnet 28 abuts against the blocking part 33 of the longitudinal groove 34, thereby causing the carrier 24 and the other carriers meshed therewith to rotate in the direction of the arrow shown. will be held. After displacement of the slider 6, the position according to FIG. 6 is achieved.

The front code conversion magnet 28 is in a position opposite the longitudinal groove 34, while the code conversion magnet 29 of the carrier 25 is in the code conversion position. Depending on the previous guest key, the code conversion magnet may be positioned out of alignment, so it is no longer possible to displace the slider. Furthermore, a new key is issued to the customer, with which he can displace any magnets corresponding to the code conversion magnet 29. These code conversions can be changed again by means of the bath owner's master key 36', the other code conversion pins then coming into the corresponding code conversion positions.

Variations on this embodiment are possible by changing the number of carriers. It is also possible to provide each carrier with multiple or one code conversion magnet.

According to the second embodiment described in FIGS. 8-12, the slider is designated by 37. The slider corresponds to slider 8 in its construction. The difference is that the slider 37 accommodates two carriers 38 and 39 located side by side at the same height. Each carrier 38 is attached to the end opposite to the insertion slit.
．． 39 adjoins a switching cam 40 which extends beyond the corresponding slider width 37' and forms switching cam edges 41, 42, 43, 44 arranged in the form of a Maltese cross.

Each carrier 38 , 38 likewise accommodates a code converting magnet 45 in the form of a final clamping element, the carrier cooperating with a corresponding retaining hole in the retaining plate 12 .

A Maltese cross-shaped switching cam 40 passes through an inner opening 46 of a fixedly mounted control member 47 . Its bearing pin 48 seats in a suitable manner on the cover of the inner housing 7. The bearing point of the control member 47 is oriented in the direction of insertion of the key. The inner opening 46 forms a blocking portion 49 with an edge perpendicular to the direction of movement of the slider 37 . Inner opening 46
are formed in such a way that in the starting position of the slider the three corners of the Maltese cross form abutment surfaces for mutually perpendicular internal opening walls 50,51. Furthermore, add 1 to slider 37.
Two stops 52 are provided, against which the rear edge 53 of the control member 47 rests. The control member is thereby prevented from rotating. Control magnet 5 when moving the slider
This rotation prevention is released only when the stroker 4 performs a substantially idle stroke. Stop 52 acts together with edge 53 during the return movement of the slider to effect the final part of the rotation of the Maltese cross into the reference position according to FIG.

A control magnet 54, which is polarized in accordance with the height of the bearing point of the control element 47, is guided in the slider 37. When using a normal key, for example a customer key, this control magnet 54 is not moved, since the end of the control magnet 54 facing the stop plate lies in the longitudinal slot of the stop plate 12.

If the lock is to be transcoded, a subsequent key is pulled in as in the previous embodiment. A corresponding range of the subsequent key disengages the permanent magnet, the code conversion magnet 45 in the form of a final locking member, and the control magnet 54 from the stop plate. After carrying out a short idle stroke, the control magnet 54 moves to the width surface 37' of the slider.
energizes the control flank 55 of the control member 47 by the end beyond and lifts the control member into the position according to FIG. 1O. This achieves that the baffle 49 is located above the level of the switching cam edge 41.

If the slider 37 is further displaced, it will be in the position shown in FIG. From FIG. 11, the carrier 3 is
It can be seen that 9 is rotated in the direction of the arrow. Slider 37
After complete displacement of the cylinder 12, the position according to Fig. 12 is obtained. In this position the carrier 39 and the code conversion magnet 45 occupy another rotational position. When the slider 37 is again brought into its starting position, the aforementioned remaining rotation of the carrier 39 is carried out, so that the code conversion magnet 45 is then in a position facing the other stop opening of the stop plate. The previously used guest key no longer aligns this undisplaced code conversion magnet, and the slider 37 cannot move forward to open the lock. A coded key will be issued to the next customer.

In a third embodiment shown in FIG. 13, the control member 56 is formed as a pawl from multiple links. The control member is an angle lever 58 supported on the housing side by a pin 57.
has. One arm 58'' is located within the range of motion of the control magnet 54. Again, the control magnet 54 and lever arm 5
There is a short empty stroke between 8°. The other lever arm 58'' supports a pawl lever 60 by means of a joint pin 59, the stop teeth 61 forming the blocking part of which cooperate with the teeth of a carrier 62 formed as a ratchet wheel.The carrier is the main tightening member for code conversion. The magnet 63 is accommodated. A spring (not shown) urges the angle lever 58 counterclockwise. Its starting position is at the stopper 6 on the housing side.
4. A spring (not shown) is also attached to the pawl lever 60, and the spring is supported by, for example, the joint pin 59, and causes the pawl lever 60 to be engaged with the carrier 62.

When a normal key is used, the permanent magnet of the slider 65 and the code conversion magnet 63 are disengaged from the stop plate 12. In this case, the control magnet 54 passes through the longitudinal slit of the stop plate 12 and does not have a blocking function.

In this third embodiment, the change in the closing sign is carried out by a subsequent key corresponding to the fence, which to some extent displaces the control magnet 54 in addition to the usual magnet pin and releases it from the stop plate. The end of the slider 65 beyond the width is located at the height of the lever arm 58° of the control member 56. The magnet 54, which controls the amount of forward movement of the slider 65, energizes the lever arm 58 and pivots the angle lever 56 after the idle stroke, for the displacement of the slider 65 and is supported on the slider 65 via the pawl lever 60. Carrier 62 is further rotated.

At that time, the code conversion magnet 63 moves the slider 65 by displacement.
occupy other positions. In this position, the code conversion magnet faces the stop hole of the stop plate 12 during the return displacement of the slider 65, so that the previously used key can no longer be closed. A new key for the hotel room door lock must be issued to each new guest. In this embodiment, the slider 65 can be associated with two similarly designed carriers 62 which are also provided with blocking elements 56 . A modification of this embodiment is that instead of the pawl lever 60, an anchor similar to that of a watch can be provided. A clock spring that can be wound up as a power accumulator is attached to the carrier or its shaft.

Lever arm 58 is not required in this starting position. Via the control magnet 54, during the advance of the slider, the anchor is commanded to rotate the carrier one step by the force of the clock spring.

According to a fourth embodiment represented in FIGS. 14 and 15, the slider is designated 66. At least one of the permanent magnets 67 supported by the slider is guided with its end facing the stop plate 12 into the stop plate longitudinal slot opening 69 . There is another stop plate slit opening lower 0 parallel to the stop plate vertical slit opening. The permanent magnet 67 used is the control magnet for the control element described above. In order to change the closure code, the next customer must use the subsequent key 6 indicated by the dashed line in Fig. 14.
8 and the subsequent key has two successive magnetic zones 71, 72 for the permanent magnet 67. The magnetic zone has a complementary range E that causes the transformation to take place. Further alignment of permanent magnets (not shown) takes place in a first region attached to the closure cord.

Zone 71 is polarized such that this zone exerts a repulsion after insertion of the subsequent key 68. Thereby, the permanent magnet or control magnet 67 is moved to the position indicated by the dashed line in FIG. A subsequent displacement of the key together with the slide 66 causes the energization of the control member in the path of the control magnet 67.

After complete advancement of the slider, the position occupied by the dash-dotted line in FIG. 15 is obtained. Permanent magnet 67 to another oscillating position by zones 72 magnetized with opposite polarity in this position
displacement is performed. In order to enable the oscillating movement of the permanent magnet, the end of the lower capacity lower 3 opposite the key is circular and the opposite end is elliptical. The vertically long part of this ellipse is located horizontally with respect to the moving direction y of the slider 66. In order to prevent the permanent magnet 67 from swinging prematurely, the stopper 1
2 has a thickened section, designated 12°, between the longitudinal slit openings, in front of which the lower end of the permanent magnet is located when the desired displacement is achieved. End 67 not displaced through zone 72
is drawn into the adjacent stop plate slit opening lower 0 and remains there during further closing operations with this key 68. In contrast, a previously used key cannot cause the slider 66 to move. Further conversions can only be carried out with a newly issued subsequent key which forms a correspondingly magnetized zone.

The modification allows a circular stop plate blocking opening to be selected instead of the control plate longitudinal slit opening 69.

In that case, the permanent magnet 67 acts like any other permanent magnet. The permanent magnet is always returned to the stop plate retaining hole after returning the slider to its starting position. A successor key is used for code conversion and corresponds to key 68. This means that in the advanced position of the slider a rocking movement takes place, after which the liberating section or magnetic zone 72 draws the undisplaced end 67' into the opening lower 0 of the stop plate area. Such a configuration is independent of the control functions for the carrier.

The fifth embodiment is made clear by FIGS. 16 and 17. The slider 74 is provided with a vertical hole 75 facing laterally to the direction of movement. Two centrally opposed bearing recesses 7 from the bearing recess 76 facing the stop plate 12 of the slider.
6 has started, and a bearing pin 77 is engaged in the bearing recess. The bearing pin is a component of a cylindrical sleeve 79 made of synthetic resin surrounding the permanent magnet 78. If the key is not inserted, the polarized end 78'' of the permanent magnet 78 facing the stop plate 12 is drawn into the stop plate longitudinal slot opening 80 located in the direction of movement of the slider 74 until it hits the guide plate 9. The vertical slit opening 80 of the stopper plate has a T angle with respect to the horizontal slit 81 at the end opposite to the insertion slit 4.
formed into a shape.

When a subsequent key 82 is inserted, the complementary area E which effects its transformation is divided into two side by side magnetized zones 83.8 of opposite polarity.
4, and the permanent magnet 78 is repelled by the zone 83. The permanent magnet thereby reaches the position shown in FIG.
In this position the end 78'' facing the key still has a vertical slit 8
Stay within 0. This means that the bearing recess 76 is connected to the permanent magnet 78.
This is achieved by restricting the movement of The end of the magnet bin that extends beyond the corresponding slider width area during the advance serves for the control of a control element which performs a conversion of the code bin on the carrier side. The permanent magnet or control magnet 78 is pivoted as soon as it reaches the transverse slit 81, since it is subjected to the attractive force of the 180° magnetic zone 84 and drawn into the longitudinal slit 80. Further use of subsequent key 82 results in loss of control of permanent magnet 78 and does not effect the conversion. The conversion must be carried out by another key whose magnetic range is correspondingly polarized.

If the permanent magnet 78 is used as a control magnet and only one stopper hole is provided for this purpose, different closing possibilities can be obtained by means of corresponding keys. This means that after closing with a key, closing is only possible with another key. Multiple locking with keys is not practicable.

Variation can be achieved by having the key have an additional code. This additional code is formed upon insertion of the key. If the key has the correct code, the blocking part for the conversion to take place is in the active position and a displacement of the permanent magnet or a displacement of the code conversion magnet held by the carrier takes place.

The retaining plate retaining hole and the retaining plate vertical slit can also be provided in the additional plate as required. The accumulator can also be connected to the slider in such a way that it is rolled up a certain amount during the angular slider displacement. Because the slider repeatedly changes code due to frequent standard key operations, this is done quietly to avoid static electricity.

The end of the magnet pin beyond the slider width serves for the control of a control member, which performs a conversion of the code pin on the carrier side. Permanent magnet or control magnet 78 has horizontal slit 81
The reason is that permanent magnets, etc.
This is because the attractive force of the magnetic zone 80' is applied to the magnetic field 80' and the magnetic field 80 is drawn into the vertical slit 80. Further use of subsequent key 82 results in loss of control of permanent magnet 78 and does not effect the conversion.

The conversion must be carried out by another key whose magnetic range is correspondingly polarized.

If the permanent magnet 78 is used as a control magnet and only one stopper hole is provided for this purpose, different closing possibilities can be obtained by means of corresponding keys. This means that after closing with a key, closing is only possible with another key. Multiple locking with keys is not practicable.

Variation can be achieved by having the key have an additional code. This additional code is formed upon insertion of the key. If the key has the correct code, the blocking part for the conversion to take place is in the active position and a displacement of the permanent magnet or a displacement of the code conversion magnet held by the carrier takes place.

The retaining plate retaining hole and the retaining plate vertical slit can also be provided in the additional plate as required. The accumulator can also be connected to the slider in such a way that it is hoisted a certain amount upon each slider displacement. Due to frequent standard key operations, the slider often repeats code conversion displacements, so this is done quietly to avoid static electricity.

All new features presented in the description and drawings are essential to the invention, even if they are not mentioned in the claims.
