EP0304760A2 - Locking system consisting of a lock and several keys - Google Patents

Abstract

The invention relates to a locking system consisting of a lock and a plurality of keys, in which the locking of the lock determined by mechanically and/or magnetically controllable tumblers can be varied in such a way that the locking code of the lock initially corresponding to the coding of the first key can be changed to the coding of a subsequent key by the displacement of at least one tumbler member (28) within the lock, and proposes, at the same time doing away with actuation by tool or hand-operated knob, that the displacement of the tumbler member (28) be obtained by means of the particular subsequent key (36), and that the subsequent key (36) be subdivided into a first region (A) assigned solely to the locking code of the tumblers and a second additional region (E) which comes into effect when the first region coincides with the locking code of the tumblers and which displaces the tumbler member (28) into the position covered by the additional region of the next subsequent key. <IMAGE>

Description

The invention relates to a locking system, especially for door locks, according to the preamble of the main claim.

In the known solutions of this type which operate on magnetic locking release (EP-PS 24 242), the recoding is carried out by a tool which can be inserted into the lock from the outside through an opening in the lock cover, for example in the form of a socket wrench. This engages in the center of a rotatable carrier. At least one permanent magnet forming the tumbler is seated in the rotatable carrier. The carrier can be locked in different angular positions. Every other angular position embodies a different magnetic coding of the lock. This type of recoding is user-unfriendly and affects operational security, including burglar security. There is primarily the risk that someone can unauthorizedly carry out the rotation adjustment of the carrier with a tool and that the lock can no longer be opened with the key previously intended. Significant difficulties can arise if it is not certain, in particular when there are several rotatable carriers, in which position they have been rotated. These possibilities alone require that the ability of the lock to be converted is not brought to the attention of all lock users, and that this knowledge and the associated tools are specific Confidants remains limited. Accordingly, the recoding of the lock cannot be used in the normal normal operational sequence, as it often occurs in hotel lock systems that operate purely electrically, for example. In the relevant locks, which work with pure magnetic track coding and on an electronic basis, recoding has already been proposed in order to increase operational security in such a way that a key issuing device which exists in the hotel reception issues a different key for each subsequent guest in a certain update program or the like in such a way that the hotel door lock no longer accepts the previous guest key as a suitable key after using this new guest key (see DE-PS 24 01 602). If you want to avoid line connections from the reception computer to every hotel door lock, the hotel door lock must have saved a corresponding update program. This considerably complicates such lock systems. On the other hand, this version also requires voltage sources in each individual hotel door lock and has the disadvantage that malfunctions occur if a guest with a newly issued key does not enter his room at all and leaves the hotel without entering the room, in which case the subsequent guest has a key who the room door lock cannot accept because the guest key in between has never become known to him.

In the case of mechanical lock release designs of locks that can be locked with colored keys, recoding of the locking code of the tumblers is known, in such a way that when operated with the first key, a lock must also be released by hand, which one by compound intervention the tied basic position of the tumblers cancels, after which by operating the lock by means of a successor key the classification of the tumblers to the locking code of the successor key sels happens including restoration of group intervention. These types of construction also have the same disadvantages in terms of operation. If the key is lost, only the lock is destroyed.

It is then known from US Pat. No. 3,234,768 to make a change in the permutation of cylinder locks. In one of the pin tumblers of this solution, a tumbler in the form of a ball is provided between the core pin and the housing pin. At the level of the point of separation between the pin bore and the rotary joint of the cylinder core, the lock cylinder housing forms a channel that extends outwards, the diameter of which is slightly larger than that of the ball. If this cylinder lock is actuated with a first key, this arranges the special pin tumbler in addition to the other pin tumblers so that the separation point between the ball and the housing pin lies at the level of the core twist joint. If this first key is to be locked out, this can be done with a successor key, the so-called owner key. This controls the special pin tumbler during the key insertion movement in addition to the other pin tumblers so that the separation point between the core pin and the ball is located at the level of the core twist joint. During the subsequent closing rotation, the ball comes out through the channel. Then the special pin tumbler works like the others. A lock actuation can no longer be carried out by means of the first key. Furthermore, no further change in permutation can be achieved unless the ball is reintroduced in any way.

The object of the present invention is to design a locking system of the generic type in such a way that recoding is possible without the need to operate a tool or a button, which in particular also involves the normal use of the locking system due to a forced sequence of key use with the least possible effort cash, for example in hotel locking systems could also be given to the guests' area of competence.

This object is achieved by the invention specified in the main claim. The subclaims represent advantageous developments.

As a result of this configuration, a locking system is created in which the successor key inevitably effects the recoding, ie solely through its use. The lock housing therefore no longer needs to have any special additional tool insertion openings, for example. It gains security against burglary and abuse because the recoding cannot be carried out by any plug-in tool. The key holder does not even need to know that he has received a key to carry out the changeover. He actuates the lock in the usual way with this key, without knowing that a recoding takes place at all with this actuation. The previous key is locked out; it is therefore not possible to switch back to its coding with it. It is therefore possible, with relatively little effort, to achieve a recoding option that allows the optimal use of such locks in the area of hotel locking systems: The next guest decodes his hotel room door lock by opening the first time with the key received, so that the key of the previous hotel room guest locks the lock couldn't close anymore. The successor key is then the normal key. There is also an imperative to use the successor keys. It is not possible to skip the successor key. In practice, this means that the successor keys can only be used one after the other, which considerably reduces misuse. If, for example, a successor key is overturned, the corresponding tumbler cannot be issued prematurely from the supplementary area Subsequent key are recorded. The tumbler has not yet been relocated from the intended successor key. This system is also suitable for cylinder locks. After relocation, the tumbler is still in a position to be recorded by the successor key. In contrast to the cylinder locks according to the prior art, the tumbler link is therefore still included in the permutation of the lock after using the successor key. In this way, a rhythmic return, a so-called repeat, can be achieved in the relocation of the tumbler links, both for locks with mechanical and magnetic coding.

In all magnetically working embodiments, the lock illustrated in FIGS. 1 and 2 has an elongated lock housing 1 to be assigned to a door (not shown). At one end of this lock is a rotary knob 2, with the aid of which a latch or bolt can be withdrawn, provided that Lock is in the locked position.

The rotary knob 2 can be coupled to a pusher mandrel 3 which is square in cross section and which carries an inner knob (not shown) lying on the inside of the door. By means of the latter, the latch or bolt which is not shown can be withdrawn at any time.

In order to be able to operate the lock from the outside of the door, the lock housing is provided on the end face opposite the rotary knob 2 with an insertion slot 4 into which a card-like key 5 can be inserted. With regard to the key 5, the card is provided with a magnetic coding of sufficient rigidity to be able to displace a slide 6 guided inside the lock housing 1 by means of this card.

To accommodate the slide 6 is used in the lock housing 1 inner housing 7, which two parallel to Slide 6 arranged guide plates 8 and 9 carries. With regard to the guide plate 8, it is a plate made of ferromagnetic iron, while the other guide plate is designed to be non-magnetic. The guide plate 8 is thicker than the guide plate 9 adjacent to it and is loaded by a leaf spring 10, which in turn is supported on the bottom 11 of the inner housing 7. Before the key 5 is inserted, the guide plates 8, 9 lie flat against one another. If the key 5 occurs between the guide plates 8, 9, the guide plate 8 deflects resiliently in the direction of the base 11.

The anti-magnetic guide plate 9 is in turn supported on a blocking plate 12 made of non-magnetizable material. For the latter, brass is used in the exemplary embodiment. Circular blocking openings 13 are located in the blocking plate 12 in a corresponding distribution, which correspond to blind bores 14 of the same in the starting position of the slide 6. In some of the blind holes, pin-shaped permanent magnets 15 are let in, which in turn are attracted to the guide plate 8 and thereby pass through the blocking openings 13. Depending on their arrangement, the permanent magnets act on the guide plate 9 with either its south or north pole. The slide 6 can therefore not be moved. It is otherwise under the action of a tension spring 16 which loads it in the direction of the insertion slot 4. The tension spring 16 engages on one end on a pin 17 of a cover 18 covering the slide 6 and on the other end on a control projection 19 extending from the slide 6. The latter is equipped with an inclined surface 20, by means of which, when the slide 6 is advanced, a leaf spring 21 fastened at the level of the insertion slot 4 on the inner housing 7 can be displaced in the direction of the arrow X, dragging a coupling sleeve 22 and thereby turning the knob 2 in the coupling position Lever pin 3 brings what allows the subsequent opening of the door.

The advancement of the slide 6 is, however, only possible after inserting the prescribed key 5, which is supported in its fully inserted position with its front edge 5 'on an inward lock shoulder 23 of the slide. In the key insertion position, the corresponding permanent magnets 15 are then aligned with the magnetization regions of the key positioned accordingly. As a result, the permanent magnets are repelled in the direction of the blind bores 14 and consequently leave the locking openings 13 of the locking plate 12.

For the purpose of changing the magnetic locking code, according to the first embodiment, the slide 6 contains four mutually coupled, rotatable carriers 24, 25, 26, 27, each of which is equipped with a recoding magnet 28, 29, 30, 31 designed as a tumbler. On the outside, the carriers 24 to 27 are provided with teeth with which they mesh with one another. To accommodate the carrier 6, holes 32 are machined in the slide. The carriers, each equipped with a recoding magnet, are arranged relative to one another in such a way that the recoding magnets successively step into the position in front of an obstacle or out of this position due to the rotary movement of the carriers. The obstacle 33 is formed by a transverse edge of a longitudinal groove 34 which extends in the direction of displacement y of the slide 6. Since there are four recoding magnets or tumbler members, four such longitudinal grooves 34 are also provided. They are located in the cover 18 of the inner housing 7 that overlaps the slide 6. The two longitudinal grooves 34, which are arranged further inward of the lock, are at a greater distance from one another than the other two longitudinal grooves 34.

Of the four recoding magnets 28 to 31, however, only one serves as a real recoding magnet or a real tumbler. 4 and 5, this is the recoding magnet 28. With its facing the locking plate 12 At the end, when the follower key 36 is not inserted, it protrudes into a longitudinal slot 35 of the locking plate 12 lying in the direction of displacement. The remaining recoding magnets 29, 30, 31 can then dip into corresponding locking openings 13 of the locking plate 12, so that in this case they perform a function similar to the permanent magnets .

If the lock is assigned to a hotel room door, for example, the guest has a guest key that is comparable to key 5. Through this, all permanent magnets 15 and recoding magnets 29, 30, 31 are displaced such that they disengage from the blocking openings 13. The slide 6 can thus be displaced in the direction of the arrow y to produce the coupling to the rotary knob 2. Only the recoding magnet 28 or the tumbler is not displaced in this case. The slide movement is nevertheless possible through the longitudinal slot 35 of the locking plate 12.

If another guest moves into the previously used hotel room, the lock is recoded beforehand on the hotel side using the command key illustrated in FIG. 5 and serving as the successor key 36. This includes a first area A, which is assigned to the locking code, and an additional area E, which initiates the changeover. The corresponding areas are illustrated in broken lines in FIG. 5. All the permanent magnets are brought out of engagement with the locking plate 12 by the first region A and the recoding magnet 28 or tumbler element is brought out of engagement by the supplementary region E. The recoding magnet 28 therefore dips into the longitudinal groove 34. In the subsequent slide displacement in the direction of arrow y by means of the successor key 36, the corresponding end of the recoding pin 28 then abuts the obstacle 33 of the longitudinal groove 34 and thereby forces the carrier 24 and the further carriers meshing with it to rotate in the direction of the arrow shown. After shifting the slide 6 then reached the position shown in FIGS. 6 and 7. The previous recoding magnet 28 has left its aligned position with the longitudinal groove 34, while the recoding magnet 29 of the carrier 25 has entered the recoding position. Using the previous guest key, it is therefore no longer possible to shift the slide because of the then relocated recoding magnets or tumbler links. Furthermore, the new guest must be given a modified guest key, by means of which he can shift all of the magnets except for the recoding magnet 29 accordingly. This recoding can also be changed again by means of a successor key 36 ′ on the hotel side, which also has the areas A and E, a different recoding pin then entering the corresponding recoding position, see FIG. 7.

Variations on this embodiment are possible in that the number of carriers is changed. It is also possible to equip each carrier with more than one recoding magnet.

According to the second embodiment illustrated in FIGS. 8 to 12, the slide is designated by the number 37. The structure of the slide corresponds to that of the slide 8. One change is that the slide now accommodates two supports 38 and 39 lying next to one another at the same height. At its end facing away from the insertion slot, each carrier 38, 39 continues into a switching cam 40 which projects beyond the corresponding slide broad surface 37 'and which forms switching cam edges 41, 42, 43, 44, which in turn are arranged in the manner of a Maltese cross. Each carrier 38, 39 also receives a locking magnet-like recoding magnet 45, which interacts with a corresponding locking opening of the locking plate 12.

The Maltese cross-like switching cam 40 extends through an inner opening 46 of a fixedly mounted control member 47. Whose bearing pin 48 sits in a suitable manner on the ceiling 18 of the inner housing 7. The bearing point of the one-armed control member 47 faces the direction of insertion of the key. With an edge lying approximately perpendicular to the direction of displacement of the slide 37, the inner opening 46 forms an obstacle 49. The inner opening 46 is designed such that in the starting position of the slide three corners of the Maltese cross form stop faces for two inner opening walls 50, 51 which are at right angles to one another. Furthermore, a stop 52 is provided on the slide 37, against which the rear edge 53 of the control member 47 occurs. This secures the latter against rotation. When the slide is displaced, this securing is only canceled when the control magnet 54 has approximately passed the idle stroke. The stop 52 also causes, together with the edge 53, the last part of the remaining rotation of the Maltese cross into the basic position according to FIG. 8 when the slide is moved back.

A correspondingly polarized control magnet 54 is guided in the slide 37 at the level of the bearing point of the control member 47. When using a normal key, for example a guest key, this control magnet 54 is not moved because the end of the control magnet 54 facing the locking plate runs in a longitudinal slot of the locking plate 12.

If the lock is to be recoded, a follow-up key should be used as in the previous embodiment. Through the corresponding areas of the same, the permanent magnets, the interlocking recoding magnet 45 and the control magnet 54 are brought out of engagement with the locking plate. After passing through a small idle stroke, the control magnet 54 acts with its end, which projects beyond the wide surface 37 'of the slide, on a control flank 55 of the control member 47 and lifts it into the position according to FIG. 10. This ensures that the obstacle 49 is then at the level of the switching cam edge 41 lies. With further displacement of the slide 37, the position shown in FIG. 11 is reached. From this it can be seen that the carrier 39 is rotated in the direction of the arrow by the obstacle 49. After the slide 37 has been completely advanced, the position according to FIG. 12 is then present. In this, the carrier 39 and the recoding magnet 45 consequently assume a different rotational angle position. If the slide 37 is now brought back into its initial position, the above-mentioned residual rotation of the carrier 39 takes place, so that the recoding magnet 45 is then aligned with another locking opening in the locking plate. The guest key previously used then no longer classifies this relocated recoding magnet, and the slide 37 can accordingly not be advanced in order to open the lock. If it is a locked hotel room door, the following guest must be given an appropriately coded key.

In the third embodiment modified in FIG. 13, the control member 56 is designed in the manner of a multi-unit pawl. It has an angle lever 58 mounted on the housing side of the pin 57. Its lever arm 58 'lies in the range of motion of a control magnet 54. Again, there is a short idle stroke between the control magnet 54 and the lever arm 58'. The other lever arm 58˝ carries by means of a pivot pin 59 a ratchet lever 60, the blocking tooth 61 which forms an obstacle interacts with the teeth of the carrier 62 designed as a ratchet wheel. This receives a recoding magnet 63 which represents the tumbler. A spring, not shown, loads the angle lever 58 counterclockwise. Its starting position is limited by a stop 64 on the housing side. Also assigned to the pawl lever 60 is a spring, not shown, which sits, for example, on the pivot pin 59 and which forces the pawl lever 60 into tooth engagement with the carrier 62.

If the usual key is used, the permanent magnets of the slide 65 and the recoding magnet 63 are brought out of engagement with the locking plate 12. The control magnet 54 runs through a longitudinal slot of the locking plate 12 and accordingly does not perform a locking function.

In this third embodiment, the change of the locking code is also to be carried out by means of a corresponding follow-up key, which in addition to the other magnetic pins also shifts the control magnet 54 with its areas and lifts it out of the locking plate. Whose end of the slide 65 projecting end is thus at the level of the lever arm 58 'of the control member 56. During the forward movement of the slide 65, the control magnet 54 acts on the lever arm 58 after an idle stroke and pivots the angle lever 56, whereby according to further advancement of the slide 65 and Via the ratchet lever 60, the carrier 62 mounted in the slide 65 is rotated further. The recoding magnet 63 receives a different position relative to the slide 65 by being moved. In this position, when the slide 65 is moved back, it is aligned with a locking opening of the locking plate 12, so that the key previously used then no longer closes. A new key, if it is a lock for a hotel room door, must be given to the new guest. In this embodiment, the slide 65 can also be assigned two supports 62 of the same design with locking member 56. A modification of this embodiment could be made in that an anchor is provided instead of the pawl lever 60 as in a clockwork. A wind-up clock spring is then assigned to the carrier or its axis as an energy store. The lever arm 58 is not required in this embodiment. When the slide is advanced, the armature receives the command via the control magnet 54 to let the carrier rotate one step further, which force then results from the clock spring.

According to the fourth embodiment illustrated in FIGS. 14 and 15, the slide has the reference number 66. At least one of the permanent magnets 67 carried by it is guided with its end facing the locking plate 12 in a locking plate longitudinal slot opening 69. A further blocking plate longitudinal slot opening 70 runs parallel to this. With regard to the permanent magnet 67, it can be a control magnet for a previously described control element. For the purpose of changing the locking code, the next guest receives a follow-up key 68, shown in dash-dot lines in FIG. 14, which has two magnetic zones 71, 72 lying next to one another for the permanent magnet 67. The latter form the supplementary area E. which causes the changeover. The classification of the other permanent magnets, not shown, takes place with a first area assigned to the locking code. Zone 71 is polarized in such a way that it acts on repulsion after insertion of successor key 68. As a result, the permanent magnet or control magnet 67 is shifted into the position shown in broken lines in FIG. 14. Subsequent displacement of the key with slide 66 causes the control member located in the path of the control magnet 67 to be acted upon. After the feed of the slide has been completed, the dot-dash position in FIG. 15 is reached. In this there is a pendulum displacement of the permanent magnet 67 into the other pendulum position, caused by the reversely polarized magnetic zone 72. In order to allow the pendulum-shaped movement of the permanent magnet 67, the end of the receiving opening 73 facing away from the key is circular and the opposite end is oval. The longitudinal extent of this oval lies transversely to the direction of displacement y of the slider 66. So that the permanent magnet 67 does not swivel prematurely, the locking plate 12 between the longitudinal slot openings has a thickening designated 12 ', in front of which the lower end of the permanent magnet occurs during an attempted displacement. Through zone 72, the relocated end 67 'in the adjacent locking plate length slot opening 70 is drawn in and remains there during the further closing operations by means of this successor key 68. The key previously used, on the other hand, cannot move the slide 66. A further change can only be caused by a renewed successor key, which forms correspondingly magnetized areas.

A modification is possible in that a circular locking plate locking opening is selected instead of the control plate longitudinal slot opening 69. Then the permanent magnet 67 acts like the other permanent magnets. It always returns to the locking plate locking opening after the slide has been returned to its starting position. A successor key that corresponds to key 68 is then used for recoding. This means that in the forward position of the slide the pendulum movement takes place, after which the key magnetization or the magnetic zone 72 pulls the relocated end 67 'into the locking plate longitudinal slot opening 70. Such a configuration is then independent of a control function for a carrier.

The fifth embodiment results from FIGS. 16 and 17. The slide 74 is provided with an elongated recess 75 running transversely to its direction of displacement. From the side of the slide facing the locking plate 12, two opposite bearing recesses 76 extend in the center, into which bearing pins 77 are inserted. The latter are part of a cylindrical sleeve 79 surrounding a permanent magnet 78 and made of plastic. If the key is not inserted, the polarized end 78 'of the permanent magnet 78 facing the locking plate 12 is drawn into a locking plate longitudinal slot opening 80 lying in the direction of displacement of the slide 74 up to the guide plate 9 The blocking plate longitudinal slot opening 80 widens at the end opposite the insertion slot 4 in a T-shaped arrangement to a transverse slot 81.

If a follow-up key 82 is now introduced, the supplementary area E which causes the changeover has two adjacent, oppositely magnetically polarized zones 83, 84, the zone 83 applies the permanent magnet 78 to repulsion. It thereby reaches the position illustrated in FIG. 16, in which the end 78 'facing the key still remains within the longitudinal slot 80. This is achieved in that the bearing recesses 76 limit the movement of the permanent magnet 78. During the advance, the end of the magnetic pin projecting beyond the corresponding slide width area can be used to control a control element which recodes a coding pin on the carrier side. The permanent magnet 78 thus serves as a control magnet. As soon as the permanent magnet or control magnet 78 has reached the transverse slot 81, it pivots by 180 degrees because it is exposed to the attractive force of the magnetic zone 84 and is drawn into the longitudinal slot 80. A further use of the follower key 82 then does not result in the permanent magnet 78 being driven and thus in no recoding. Again, this must be done using a further key, in which the magnetic areas are appropriately polarized.

If the permanent magnet 78 is not used as a control magnet and only one locking plate locking opening is provided for it, an alternate lockability can be achieved by means of appropriate keys. This means that after locking by means of one key, locking is only possible by means of another key. A repeated closing by means of a key in a row is then not feasible.

A variant could be achieved in that the key receives an additional coding. This additional coding is evaluated when the key is inserted. If the key has the correct coding, then a Obstacle controlled in the operative position, by means of which a recoding takes place, be it a displacement of a permanent magnet or a displacement of a recoding magnet held by a carrier.

The blocking plate openings and blocking plate longitudinal slots can optionally also be provided in an additional plate. The energy accumulator can be coupled to the slide in such a way that it is pulled up by a certain amount each time the slide is moved. Since the slider is operated more often without changing the position due to the more frequent normal key actuation, it is statistically evident that it never completely discharges.

The lock shown in Figures 18 to 27 has a box-like lock housing 85 with a lock base 86 and from this lock case side walls 87, 88, 89 and 90. The lock set out below is overlaid by a lock cover 91. The latter contains a center in the longitudinal direction of the Lock-extending key insertion opening 92.

A centering mandrel 93 extending from the bottom of the lock 86 extends into the center of the key insertion opening. Between this and the lock case side wall 88, a pin 94 extends from the lock base 86, on which the lock cover 91 is also supported and in which a lock cover fastening screw engages. The pin 94 also serves to longitudinally guide a plate shaped, the lock base 86 adjacent carrier 95, which is equipped in the region between the pin 94 and the lock case side wall 88 with a fixing tooth 96. This extends to the underside of the lock cover 91. In the central area, the carrier 95 is equipped with a key opening 97. Above this there is a recess 98 which forms a locking shoulder 98 'with a lower flank. In front of this is an angled portion 99 of a locking lever 101 mounted below the carrier 95, which is spring-loaded in the direction of engagement by means of a leaf spring 102.

The carrier 95 is adjacent a bar 103. It forms a thicker, the lock case side wall 90 penetrating bolt head 103 ', to which the thinner bolt tail 103˝ connects. The end of the same is slotted for guiding engagement of the pin 94. In the middle, the bolt tail 103˝ is equipped with a control opening 104. On the side facing away from the carrier 95 there is a recess 105 on the bolt for receiving a bolt rocker 106. This is supported by a bolt 107 on the bolt side and serves to form the locking engagement recess 108 of the bolt control opening 104. A leaf spring 106 'acts on this bolt rocker 106 in Clockwise direction, which rocker receives a support on the lower flank of the recess 105.

At the bolt head 103 'is followed by a touring projection 109 extending in the closing direction of the bolt, which extends to the castle ceiling 91. In the area between bolt tail 103˝ and touring protrusion 109 there is a locking opening 110 for a locking tooth 111 of a tumbler plate 112 which rests on bolt bolt 103˝ and can be pivoted about pin 94. Above this, seven tumblers 113 of identical design extend. In contrast to tumbler plate 112 the pivot point of the tumblers 113 can be changed. For this purpose, the Fixing tooth 96 facing area of each tumbler 113 from an arc slot 114, which is penetrated by the pin 94. The edge edge, which runs concentrically to the arch slot 114, is equipped with a toothing 115. Depending on the basic position of each tumbler 113, the fixing tooth 96 engages in a corresponding tooth gap. The end of each tumbler 113 and the tumbler plate 112 opposite the toothing 115 is provided with a stepped tour opening 116. All tumblers form a central control opening 117 and are acted upon counterclockwise by leaf springs 118 in such a way that they are supported on the touring projection 109 when the bolt 103 is closed, see FIG. 21.

With regard to the key illustrated in the figures, it is a follow-up key 119. It has a key shaft 120 and a key handle 121. An opening 122 with a circular cross section extends from the lower end of the key shaft 120 to the entry of the centering mandrel 93.

In the radial extent, a locking code beard step area A unloads from the key shaft 120. It comprises seven beard levels 123, which are used to classify the tumblers 113. An extension area E follows in the extension of the locking code area. The beard step 124 directly adjacent to the beard steps 123 serves to control the tumbler plate 112. The next, wider beard step 125 is provided to control the bolt 103. This is followed by a beard step 126, by means of which the release position of the carrier 95 can be brought about. The lowest beard step 127 in turn serves to control the locking lever 101. In diametrically opposite relation to the beard steps 124 to 127, the supplementary area E has a driver wing 128 which extends exclusively in the plane of the tumbler plate 112 and the bolt tail 103 ", forming a gap 129 that on Arranged at the height of the beard steps 126 and 127 is a trigger safety wing 130. Furthermore, an additional beard step area B is provided in diametrical opposite to the locking code beard steps 123, the beard steps 123 'of which embody the new locking code.

The closing method is as follows:

The key can only be removed when the bolt 103 is locked. If the locking code used, for example, by a previous user is to be changed over, a prescribed sequence key 119 is handed over to the subsequent user. This encompasses the beard level areas A, E and B. The beard level area A corresponds in its locking code to the locking code used in the previous key, while the additional beard level area B embodies the new locking code. Since the trigger securing wing 130 lies on the same side as the beard step area B, the wing serves as an orientation aid when inserting the follow-up key 119 into the lock. The insertion movement is limited by the lock base 86, so that the corresponding beard steps are then aligned with the corresponding parts of the lock fitting, see FIG. 20. When the closing rotation then begins, the tumblers 113 of the area A assigned to the lock code are pivoted in such a way that their Tour openings 116 lie on top of one another and thus allow the bolt 103 to be withdrawn, the tour projection 109 moving into the tour openings 116. This is possible because of the tumbler plate 112, which is simultaneously disengaged from the beard step 124. During the closing rotation from the position according to FIG. 22 to that according to FIG. 24, the latch 103 becomes approximately one third larger from the beard step 125 acting on a control edge 104 ' withdrawn from its total closing path. Level 125 therefore causes a partial relocation of the bolt to prove the authorization to change over. Furthermore, from the beard level 127 of the supplement area ches E the locking lever 101 raised, its angled 99 away from the locking shoulder 98 ', see dash-dotted line in Fig. 22. This releases the carrier 95 for displacement. The corresponding displacement of the carrier takes place in that the beard step 126 abuts a driving shoulder 97 'of the key engagement opening 97. Carrying the carrier 95 into the position according to FIG. 24 leads to the fixing tooth 96 leaving the toothing 115 of the tumblers 113. In this position rotated by 180 °, the trigger safety wing 130 is also pivoted under the carrier 95, so that the key cannot be removed from this position. Furthermore, the key can no longer be turned back from this position, since the locking lever 101 has fallen back into its starting position and is therefore in the range of rotation of the beard step 127. The key must therefore continue to be turned clockwise. 25, the driver wing 128 of the follower key 119 acts on the bolt rocker 106. Furthermore, the spring-loaded tumblers 113 are shifted into their new basic position by the beard steps 123 'of the additional beard step area B, which is possible because of the fixing tooth 96 which is still in the release position. 26, i.e. after covering a total rotation angle of 360 °, the beard step 126 of the supplementary area E comes up against another driving shoulder 97˝ of the key engagement opening 97 of the carrier 95 and thus shifts it in the closing direction, whereby the fixing tooth 96 falls into the corresponding tooth gaps of the toothing 115 of the tumblers 113, capturing the different basic positions of the tumblers. Then the driver wing 128 is immersed in the locking engagement recess 108 during this remaining rotational path and has thus completely moved the bolt back. In this position, the locking tooth 111 of the tumbler plate 112 engages in the locking opening 110 of the touring projection 109, which is not shown. From this position is the successor key 119 not removable, since the beard step 127 engages under the carrier 95.

The locking of the bolt 103 now requires an opposite closing rotation, that is to say counterclockwise. The driver wing 128 dips into the locking engagement niche 108 of the bolt 103 formed by the bolt rocker 106 and entrains it. The gap 129 between the driving wing 128 and the trigger locking wing 130 causes the key not to come into contact with the carrier and locking lever. During this closing rotation, the tumblers 113 are also shifted from the additional beard step area B. After a return rotation of 180 °, the bolt 103 then assumes its pre-closed position from which the follower key 119 can be removed. To close the bolt, the successor key must then be inserted so that the additional beard step area B, i.e. the new area, is on the left. In the closing rotation that then follows, the locking lever 101 and the carrier 95 are not displaced. Only the tumblers are correctly classified, so that then only the bolt is closed back via the driving wing 128 of the successor key 119. The return rotation is finished after about 180 °, so that the position shown in FIG. 26 is then again present.

A key following the successor key 119 would then look such that it receives the beard step area B above the beard steps 124, 125, 126, 127. A new additional beard step area would then have to be provided in a diametrically opposed position.

From the above it can be seen that the change does not concern the supplementary area E. This always remains the same. A variation is made only on the first beard step area assigned to the locking code.

Then it should be noted that the supplementary area E of the key only comes into effect when the first area -beard level area A- matches the locking code of the tumblers. If this is not the case, the tumblers prevent a closing rotation.

The lock, designed as a lock cylinder 131, has a housing 132 which is circular in cross section. In a central bore 133, this receives a cylinder core 134 which extends over a little more than half the length of the housing 132. Four rows of housing pins 135 and core pins 136 are arranged in the housing 132 and cylinder core 134 in a uniform angular distribution. Accordingly, the cylinder core has a key channel 137 with a cross-shaped cross section, into which the facing ends of the core pins 136 protrude. Pin springs 138 act on the housing pins 135, which in turn load the core pins in the inward direction. So that the pin springs 138 do not come out of the bores which receive the housing pins 135, the housing 132 is surrounded by a jacket 139.

From the side of the housing 132 opposite the cylinder core 134, a bore 140 which is larger in cross section than the core bore 133 is machined, in which a changeover ring 141 is rotatably supported. The latter can be locked in 90 degree positions. For this purpose, a blind bore 142 extends from the outer surface of the changeover ring 141 for receiving a locking pin 143 which is spring-loaded in the outward direction. Its cone tip works together with four latching niches 144, which are arranged in the same cross-sectional plane and are distributed around the circumference. One of these latching niches 144 extends at the level of a tumbler pin row.

In a central bore 145, which corresponds to the diameter of the core bore 133, there is a changeover core 146. The changeover ring 141 and the changeover core 146 serve to receive a single row of tumbler pins 147. These also consist of core and housing pins and are cushioned inwards . The changeover core 146 also contains an extension of the key channel 137, a cross channel 148. Its cross webs 148 'all have the same web width.

The bore 145 continues beyond the changeover ring 141 into a bore section 149 of larger cross section. A closing member 150, which is provided with an eccentrically arranged driver pin 151, rotatably projects into this. The locking member 150 contains an arc slot 152 into which a stop pin 153 of the housing 132, which is located on the same cross-sectional plane of the locking cylinder, is immersed. The length of the bore slot 152 is so large that the closing rotation of the closing member 150 is less than 90 °.

A blind bore 154 extends from the end face of the closing member 150 facing the diverter core 146 to receive a cup-shaped coupling member 155. Its pot bottom 156 faces the diverter core 146 and carries an eccentrically mounted driver pin 157. The diameter of this pin 157 is less than the width of the Cross webs 148. In the direction of its engagement, the coupling member 155 is loaded by a compression spring 158. The coupling member 155 is non-rotatable in the blind bore 154 by a radially oriented control wing 159, located at the level of the pot base 156, for which a longitudinal groove 160 extends from the blind bore 154.

The control wing 159 is equipped with an inclined surface 161 sloping in the direction of the pot edge. The latter works together with a cone tip one in the closing member 150 control pin 162 which is displaceable in the radial direction. A compression spring 163 arranged on its stepped shaft loads the control pin 162 in the direction of the inclined surface 161. The outward end of the control pin 162 interacts with a pawl 164 which is located in one of the casing side of the housing 132 outgoing longitudinal recess 165 is housed. Regarding the pawl 164, it is a one-armed lever. Whose bearing pin 166 is located near the parting line between the adjusting ring 141 and the housing 132. Approximately at the middle of the pawl 164 forms a locking projection 167 pointing in the direction of the adjusting ring 141, which protrudes into one of four locking niches 168 arranged in the same circumferential distribution. The engagement is forced by a compression spring 169 which acts on the pawl 164. When the pawl 164 is in engagement, the latching pin 143 also dips into one of the latching niches 144.

The control pin 162 then serves another function. For this purpose, it has a control zone formed by a notch groove 170 near its cone tip. The latter acts together with a stylus 171 arranged crossing the direction of movement of the control pin. For this, the control member 155 forms a corresponding bore 172. When the coupling member 155 is in engagement with the cross channel 148, the stylus 171 is supported on the lateral surface of the control pin 162. The feeler pin 171 projects beyond the separating surface between the closing member 150 and the changeover core 146. In doing so, it acts on one of four longitudinal pins 173 which are arranged in the same circumferential distribution and are accommodated in corresponding longitudinal bores 174 which completely penetrate the changeover core 146. The longitudinal pin 173 acted upon by the stylus 171 dips with its distal end into one of four blocking openings 175 of the cylinder core 134 arranged in the same circumferential distribution. 29 and 34 show that the longitudinal pins 173 of one each Compression spring 176 are acted upon in the opposite direction of their engagement.

The key channel 137 of the cylinder core 134 lies with its crosspieces in alignment with those of the cross channel 148 in the changeover core 146. One of the crosspieces 137 'is narrower than the other crosspieces, compare in particular FIGS. 38 and 39.

The lock cylinder 131 shown can be closed by means of a key 177 illustrated in FIGS. 28 and 30. The latter is cross-shaped in cross section and forms two thinner cross sections 178 and 179 arranged at right angles to one another. They correspond in thickness to the width of the cross bar 137 '. The remaining cross sections 180, 181 correspond to the width of the remaining crossbars of the key channel 137 and also the width of the crossbars 148 'of the cross channel 148 located in the changeover core 146.

The key 177 has a first area A assigned to the locking code, which extends to the point of separation between the cylinder core 134 and the changeover core 146. From there, the supplementary area E follows, which prompts a change. According to FIG. 28, a change has already been made. The cross sections 178 to 181 are provided with closing notches 182 at the level of area A. These represent the locking code notch area. When the key 177 is inserted, all the housing pins 135 and core pins 136 are therefore aligned such that their separation point is at the level of the cylindrical core surface, see FIG. 28.

The supplementary area E adjoining the first area A has control notches 183 only on the cross section 181. The remaining cross sections have no locking notches in the area there. The spring-loaded tumbler pins 147 are aligned by the control notches 183 in such a way that whose separation point is at the level of the lateral surface of the changeover core 146. A nose 184 then extends from the free end of the cross section 178. When the key 177 is inserted, however, this is offset in terms of the angle of rotation relative to the driver pin 157 and consequently does not act on the driver pin. When the key 177 is fully inserted, the nose 184 extends to the point of separation between the changeover core 146 and the locking member 150. This means that the control pin 162 is then also not displaced. The locking engagement between pawl 164 and changeover ring 141 is thus ensured. When the key 177 is turned, the cylinder core 134, the changeover core 146 and, via the coupling member 155, the locking member 150 are taken along. The rotary connection between the two cores 134 and 146 is still ensured by the one longitudinal pin 173, see FIG. 29. The changeover ring 141 remains in its position during this closing rotation, which is less than 90 degrees. This means that the key cannot be removed in the locked position. The removal of the same rather requires turning the cores 134, 146 back into their starting position.

The key 177 could indeed be inserted at a 90 ° angle of rotation. However, the tumbler pins 147 are then not classified.

If the locking of the locking cylinder is to be changed, a new key 185 is handed over to the new user. The latter is designed similarly to the previous key 177. The successor key 185 is also composed of the two areas A and E. Compared to the previous key 177, however, the cross sections 179 'and 181' are now thinner. This means that they correspond in thickness to the width of the cross bar 137 'of the cross channel 137. The remaining cross sections 178 ′ and 180 ′ are now created with a thickness that corresponds to the width of the remaining crossbars of the key channel 137.

If this follower key 185 is inserted into the locking cylinder, the position according to FIGS. 32, 33, 34, 35 and 38 results. The first area A therefore only classifies the housing pins 135 and core pins 136. The cross notch cross section 180 'in the supplementary area E does not classify the tumbler pins 147. In contrast, the nose 184 of the cross section 178 'acts on the driver pin 157 and thus shifts the coupling member 155 against spring loading. In the end position of the coupling member 155, the driver pin 157 has then left the corresponding cross bar 148 'of the cross channel 148. Along with a displacement of the coupling member 155, the control pin 162 is moved outward in the radial direction via its control wing 159. Its end pivots the pawl 164 against spring loading, its locking projection 167 releasing the facing locking recess 168. With the displacement of the locking pin 162, the notch groove 170 has also come into alignment with the feeler pin 171, so that the longitudinal pin 173 now assumes the position illustrated in FIG. 34 via the compression spring 176 and thereby cancels the joint engagement between the cylinder core 134 and the changeover core 146. During a closing rotation by means of the follow-up key 185 by 90 degrees, the cylinder core 134 with the changeover core 146 and the changeover ring 141 is therefore taken along. The locking displacement is limited by the driver pin 157, which then engages in the next cross bar 148 'of the key channel 148, that is to say after a 90 degree locking rotation. The position according to FIGS. 36 and 39 is then present. A further turning of the key forwards or backwards is then not possible. If the locking cylinder 131 is now to be actuated in the normal manner, the follower key 185 must be removed and inserted into an angular position offset by 90 degrees in order to bring the control notches 183 into engagement with the tumbler pins 147. Just like with Predecessor key incorrectly inserting the successor key 185 does not result in a locking operation.

If necessary, a modified new successor key can then be used, which changes the locking of the locking cylinder and excludes the previously used successor key 185. In this version, too, there is a mandatory sequence in the use of the successor keys. It is not possible to skip a successor key.

All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
