WO1995020087A1 - Locking system comprising a lock and several keys which fit one lock - Google Patents

Abstract

The invention relates to a locking system comprising a lock (1) and a number of keys (49, 53) which fit one lock. The appropriate keys (49, 53) which can be inserted into the lock channel have differing lock codes which actuate the locking mechanism of the lock (1). It is proposed that, in order to improve the security of the lock, each lock code should have allocated to it its own unique independently operated lock mechanism (15, 16).

Description

00001 from lock and several each to fit a lock

00002 the existing locking device 00003

00004 The invention relates to a lock and multiple

00005 ren existing keys matching a lock

00006 locking device, in which the appropriate, optional

00007 key that can be inserted into the key channel to one another

00008 different, the locking mechanism of the lock

Have 00009 locking codes. 00010

Locking devices of the aforementioned type are available in many

00012 rather known execution. It can be done by means of such

00013 locking devices overriding locking functions

Realize 00014. This is how a master key system works

00015 a single key for a certain group of people

Spent 00016, each fits into a single lock. With-

00017 of the master key, however, all keys

00018 water the master key system can be operated. In terms of

00019 the key can be magnetic, for example

00020 encoded keys that are used with magnetic

Interaction pins of the castle interact. Also are

00022 flat key known on its broad side or at

00023 form their narrow edge closing recesses for

00024 Arranging tumbler pins of a locking cylinder.

00025 is disadvantageous in such locking devices

00026 the fact that from the presence of a plurality

00027 of individual keys the higher-level locking code

00028 tion can be determined what the security value of such

00029 locking devices reduced. 00030

The object of the invention is based on the object

00032 a locking device of the type in question

00033 simple structure so that for the purpose of increasing

00034 the security of the lock from the presence of the underlying

00035 assigned keys, i.e. the single key, the locking 00036 not encoding a parent key

00037 can be determined. 00038

This problem is solved with a generic

00040 locking device in that each locking code

00041 tion in the castle, a separate, independently operable 00042 cash register that is coordinated with only one of the locking codes is assigned.

00044

00045 As a result of such a configuration, a locking device is

00046 device of the type in question of increased security

00047 value given. Regardless of the number of child keys having locking codes, the 00049 locking code of the parent key is not

00050 determinable Each locking code of a key

Namely, 00051 is assigned its own locking mechanism. Out-

Finally, 00052 this will apply when the concerned

00053 key operated. The other locking mechanism remains

00054 stirs. There is therefore no reference to the locking code

00055 with each other, from which the locking code

00056 calculation of the parent key or it-

00057 could. 00058

00059 With regard to the locking device, it can be a

00060 those with magnetic coding and actuated by this

00061 th magnetic tumbler pins of a locking mechanism

Act 00062, which with a matching key

00063 operated by shifting a clutch. In such a

Chen stands out, the invention is characterized in that

00065 each key encoding only on a partial area

00066, the remaining part of the locking code

00067 is free and has a butt edge that only the loading

00068 enforcement of a locking mechanism, while the

00069 part of the key that is free of lock coding

00070 assigned locking mechanism remains inactive. As a key 00071 serves a key card, the one partial area of which

Includes lock codes. This partial area arrives

00073 when inserting the key overlap with him

00074 associated locking mechanism and assigns the magnetic

00075 tumbler pins so that with the this area

00076 upstream impact edge taking the relevant

00077 locking mechanism takes place. The other partial area is closed

00078 encoding-free. So it has no influence on the

00079 tumbler pins. So this locking mechanism remains

00080 locked. So there is always a relocation of the

00081 one locking mechanism the other locking mechanism is not

00082 taken. The keys can also be such

00083 with different coding, e.g. in the form of magnetic

Streak or trade holes. Especially with last

00085 rer version, the security advantage is very large because

The easiest way to recognize hole codes and if

00087 regarding parent and child keys

00088 object, the easiest to analyze

00089 ren are. 00090

An advantageous further development can be seen in the fact that

00092 the locking mechanisms as with magnetic tumbler pins

00093 equipped, side-by-side slide designed and

00094 the keys are equipped with free spaces for

00095 occurs a driver stop of the locking mechanism

00096 slider, which the locking code-free part

00097 before the key is assigned. The proven one

Accordingly, the construction of corresponding locks can be retained.

00099 th. It's just the slider through an in

00100 in its direction of movement

Share 00101. According to the size of the locking mechanism slider

00102 are also the partial areas containing the codes

00103 the key to measure. If one key is

00104 is inserted, its locking code assigns the magnetic

00105 see tumbler pins of the associated locking mechanism slide 00106 a. With the pre-arranged part of this coded

00107 th abutting edge a driver stop of the closing

00108 factory-slide valve and accordingly this in the

00109 clutch position taken. The other locking mechanism

00110 slide stops because of the fact that

00111 the part that is free of locking erosion on the butt

00112 before forming a free space in which the driver

00113 strikes when the key is pushed in. 00114

00115 Furthermore, the inventive concept is transferable to a

00116 Locking mechanism with a rotatable cylinder core that with

00117 tumbler pins is populated by the coding

00118 forming key notches in the release

00119 position are classified. The essence of the invention

00120 is here two, each forming a locking mechanism

00121 cylinder core sections, each with a

00122 set of tumbler pens and which

00123 after classification by a suitable half key each

00124 for itself in a coupling position to an output element

00125 ment are relocatable. In this case, too, applies

00126 the locking codes, i.e. from the locking notches

00127 the child key not the parent

00128 key can be determined, namely due to the lack of

00129 the reference to the codes of the individual keys

00130 master key. The locking mechanism now consists of two

00131 cylinder core sections together, each cylinder

00132 core section has a number of tumbler pins.

00133 With a corresponding half key the

00134 tumbler pins of one or the other cylinder core

00135 section, so that the publishers

00136 tion of the unlocked cylinder core section in the

00137 coupling position to the output element is made possible.

00138 The other cylinder core section, however, remains

00139 locks. 00141 It is advantageous here that the two cylinder core

00142 sections as in a longitudinal division joint

00143 abutting half cylinders are designed, each half cylinder

00144 is equipped with a set of tumbler pins,

00145 assigned to which counter pins of an intermediate housing

00146 and which half cylinders each have a separate key

00147 longitudinal guide and each by means of the key in

00148 axial direction in the closed engagement position to the output

00149 element are displaceable, the intermediate housing in

00150 is rotatably arranged in an outer housing. That means,

00151 that after insertion of the corresponding half key

00152 the closing operation can already be carried out. To have to

00153 not both half keys are inserted to this

00154 to be able to. If one half key is inserted

00155 is inserted, so takes place by means of its locking notches

00156 Classification of the tumbler pins and thus the release

00157 of the relevant cylinder core section under publishing

00158 tion of the same in the clutch position. Now you can

00159 means of the half-key, the rotary movement happen.

00160 This is transmitted over the other locked cylinder

00161 the core section on the intermediate housing, which then

00162 rotates in the outer housing. 00163

00164 It proves advantageous that the output element

00165 ment in the rear end wall of the outer housing

00166 is mounted and a non-circular engagement cross-section for

00167 has projections of the cylinder core sections. Both

00168 projections complement each other to form the non-circular engagement cross

00169 section of the output element. That's enough

00170 immersing the one projection in the engagement cross

00171 cut out the output element in order to take it along

00172 effect. 00173

00174 Alternatively, it is possible that the two cylinder core

00175 sections arranged axially one behind the other in them 00176 provided intermediate housings and with one set each

00177 from tumbler core pins, which are equipped with

00178 counter pins of the intermediate housing cooperate, wherein

00179 the cylinder core sections aligned with each other

00180 Key longitudinal guides for keys of different lengths

00181 is owned by means of which a displacement of the cylinder

00182 core sections for achieving a locking mechanism

00183 handle position can be made to the output element,

00184 wherein the intermediate housing is rotatable in an outer housing

00185 are arranged. The locking codes of the key

00186 has no relation to each other in this case either.

00187 Shorter encodings, for example

00188 single key cannot lock code

Derive 00189 of the longer key. For example

00190 the shorter key inserted, so this arranges the

00191 relevant tumbler pins and allows the

00192 like the one cylinder core section under manufacture

00193 the clutch to the output element. This also happens

00194 if the longer key is used. This through

00195 engages the longitudinal key guide of the male side

00196 cylinder core section and plunges into that of the

00197 another cylinder core section with filing the

00198 tumbler pins there, so that the

00199 tion of this cylinder core section is possible. 00200

00201 This version is further developed in that the

00202 key insert-side cylinder core section back

00203 tig has a radially projecting wing

00204 ben a transfer bar of the subsequent

00205 intermediate housing and for rotating connection with it,

00206 which transmission bar with a distance in front of a radial

00207 locking wing of the inner cylinder core section 00208 ends, which has a non-circular projection in the

00209 handle cross section of the output element protrudes. The blocking

00210 wing blocks the inner cylinder core against 00211 a twisting. If the shorter key is used, then so

00212 acts upon relocation of the plug-in cylinder

00213 derkerns whose radially projecting wing the transmission

00214 supply bar, which after passing through an empty path

00215 acted upon locking wing and this out of engagement

00216 brings a niche of the outer housing. The radial flow

00217 gel is now form-fitting with the inner intermediate

00218 connected to the frame so that the same rotation

00219 is transferred to the inner cylinder core,

00220 which takes the output element with it. Relocation

00221 of the inner cylinder core section by means of the

00222 longer key also leads to a

00223 be the locking wing, so that the rotation of the cylinder core

00224 section in the intermediate housing assigned to it

00225 light is taking the output element with it. 00226

00227 It is also provided that the transmission bar with

00228 is equipped with a control cam, which with a

00229 locking bolt of the inner intermediate housing cooperates.

00230 When the transfer bar is moved forward

00231 Use of the shorter key is the locking bolt over

00232 brought the control cam into the release position. The 00233 locking bolt prevents the internal cylinder core section with the intermediate housing from being inserted into the longitudinal key guides by an auxiliary 00234 tool

00236 can be rotated. It always requires the use of

00237 regulatory key to a locking operation

00238 to be able to make. 00239

00240 So that after the closing confirmation the prescribed

00241 moderate starting position, both the locking

00242 wing as well as the inside intermediate housing

00243 gen the clutch engagement direction of a compression spring

00244 applied. 00245 00246 The variability of the configuration according to the invention is increased 00247 in that the locking mechanism can be removed and

00248 is settable. The exchange is possible because

00249 no coding reference of those belonging to a lock

00250 locking mechanisms exist among each other. This can be

00251 probably with locking devices with magnetic coding

00252 of the key as well as with locking devices

00253 chen, whose keys coding in the form of

00254 ben trains. One or both locking mechanism slides

00255 are in a locking device with magnetic coding

00256 tion can be pulled out of the lock housing and can

00257 to be replaced by others. For example, after

00258 a locking mechanism slider removed from a construction phase and

00259 by a differently coded locking mechanism slide

00260 sets, which after its insertion irreversible

00261 remains in the lock housing. With the one used previously

00262 corresponding key is then impossible to close

00263 loaned. This measure opens up the opportunity to

00264 a locking system belonging to a locking system after installation

00265 to implement all locks

00266 gig of the production of the locking devices at

00267 manufacturer. 00268

00269 The variability can still be optimized by

00270 least a locking mechanism a coding changeover

00271 has in the form of

00272 mountable magnetic pen carrier. These can take the form of

00273 be turned parts. When using the successor

00274 final ice. then through the teeth in each other

00275 gripped standing magnetic pen holder one step at a time

00276 causes rotation so that the previous key is not

00277 is more usable. This relates to

00278 several locking mechanisms of a lock additional coding

00279 opportunities. 00281 The key to actuating with magnetic coding

00282 tion provided locking device is characterized by

00283 a free-flanked butt edge for actuating a

00284 driver stop only one locking mechanism slide

00285 bers out, with the free space so far compared to the

00286 set back edge is enough as the displacement stroke

00287 of the butt-operated locking mechanism slide. Will the

00288 Key in the slot of the locking device

00289 inserted, so takes the coded area

00290 upstream impact edge the driver stop of the

00291 fenden locking mechanism slide and thus relocated

00292 this. The driver stop of the neighboring closing

00293 werk slider, on the other hand, plunges into the

00294 edge recessed space. Since the setback 00295 the displacement stroke of the εtoßkantenbetäteten

00296 locking mechanism slide, its driver

00297 immerse the stop in the free space,

00298 without putting a load on this driver stop

Practice 00299. A key that is on a partial surface

00300 forms the correct coding, but none

00301 has free space, is not able to

00302 to advance factory slider. Even if the freedom

00303 is insufficiently deep, no fully

00304 carry out constant advance so that the desired

00305 te clutch is not accessible. 00306

00307 Another key obfuscation component

00308 is that the butt and free space offset

00309 are arranged. Is the free space of the

00310 the key with the carrier

00311 impact, can not be the desired clutch

00312 can be reached. 00313

00314 operational advantages result from the fact that

00315 which a broad area of the key with a 00316 is equipped. For example, this notice

00317 whether it is a single or main

00318 key. Also, the labeling can indicate

Give 00319 that there is no reverse insertion of the

00320 key is made, which is also not that

00321 Establishing the clutch position permitted. 00322

00323 Finally, it should be mentioned that there is free space

00324 on a part that is free of locking erosion

00325 det. The coded partial area is accordingly experienced by

00326 the free space no compromise. 00327

00411 According to Figure 1 is a lock designed according to the invention

00412 1, relating to the first embodiment, on a door 2-

00413 for example a hotel room door - set. The

00414 lock 1 has a door outside

00415 lock case 3 rectangular floor plan, which on

00416 nem one end of an outer turning handle 4. With

00417 whose help a trap 5 can be withdrawn. A

00418 internal turning handles arranged on the inside of door 2

00419 be 6, however, is coupled directly to the trap 5, so 00420 that from this side of the door 2 always a door opening

00421 can be done. 00422

00423 The lock case 3 is on the outside turning handle 4

00424 opposite end with an insertion slot 7 for

00425 in the form of cards designed keys 8.9.

00426 Each of these keys has codes on only one

00427 partial surface in the form of magnetically invisible from the outside

00428 points. 00429

00430 The lock case 3 takes a multi-part lock housing

00431 10, which consists of a bottom part 11, a middle part

00432 12 and a cover part 13 there. By means of no closer

Screws illustrated in 00433 are these three parts too

00434 put together one unit. While injection molding is used for the middle part 00435, the bottom part 11 and

00436 the cover part 13 made of plastic. Between the lid

00437 part 13 and the middle part 12 are two locking mechanisms

00438-forming, parallel side-by-side locking mechanism

00439 slide 14.15 guided. With one broadside

00440 the locking mechanism slides 14, 15 on the middle part 12

00441 on. The opposite guide surface forms one

00442 locking plate 16, which is immovably received by the cover part 13. Holes 17 of the locking plate 16 are aligned in the 00444 locking position of the 00445 lock illustrated in FIG.

00446 ten bearing recesses 18 of the locking slide

00447 14.15. Magnetic are located in the bearing recesses 18

00448 tumbler pins 19 a. Εs is not necessary in

00449 to prepare a tumbler pin 19 for each bearing recess 18

00450 see there the number, location and polarity

00451 of tumbler pins 19 after the respective opening

00452 code combination of lock 1 sets. 00453 00454 is on the other side of the locking plate 16

00455 a guide plate 20, which an anchor plate 21 is opposite

00456 lies. The latter is supported by the cover part 13

00457 held the compression springs 22 in position. 00458

00459 Due to the ferromagnetic material

00460 anchor plate 21 become the magnetic tumbler pins

00461 19 attracted, the corresponding holes 17 of the

00462 Reach through locking plate 16. In this situation, the

00463 locking mechanism slide 14, 15 not from that in FIG. 3

00464 illustrated locking position to be moved because

00465 the engagement of tumbler pins 19 in the housing-fixed 00466 locking plate 16 prevents this. At the execution

00467 game is an inserted in each locking slide

00468 rotating body 23 or 24 available, which also for

00469 recording of magnetic tumbler pins is used. Everyone

00470 rotating body 23, 24 has four holes, which however

00471 are not all provided with magnetic pins. 00472

00473 A return spring 25 clamped on the housing engages

00474 on a slot passing through the middle part 12

00475 jump 26 of the locking mechanism slider 14, 15. In the

00476 Sliding joint 27 runs through

00477 through this projection 26 and makes this second

00478 lig. On the front, the protrusion 26 is provided with a control slant 28. This picks up on an obliquely

00480 angled rag 29 made of a spring material

00481 on the tongue 30, which in the area of the key insertion

00482 side end of the lock housing is fixed.

00483 that opposite the fastening end ^{1 of} the spring tongue 30

00484 end is fork-shaped and engages one

00485 annular groove 31 an internally toothed coupling sleeve 32.

00486 In the decoupled position, the coupling sleeve comprises

00487 32 a pinion 33, which with a cross-sectionally larger collar 34 in a bearing opening of the bottom part 11 00489 is rotatably arranged. The collar 34 is non-rotatable

00490 driving connection to the press mandrel 35, which ends

00491 carries the internal turning handle 6. 00492

00493 The internal toothing of the coupling sleeve 32 is a tooth

00494 wheel 36 adjusted. This is aligned with the pinion 33

00495 and carries the outside turning handle 4 on the outside of the housing.

00496 According to Figure 3, there is no coupling position between the

00497 coupling sleeve 32 and the gear 36 before, so that a 00498 rotation of the same by means of the external turning handle 4

00499 does not lead to the pushing mandrel 35. A pressure

00500 of 37 comprises the outside of the coupling sleeve 32 and

00501 loads this against the direction of clutch engagement. 00502

00503 Each locking mechanism slide 14,15 carries on its outer

00504 longitudinal edge swiveling a stop cam 38. Everyone

00505 stop cam 38 works together with a spring

00506 cut 39 of the spring tongue 30. Each end forms

00507 spring section 39 an angled detent 39 ',

00508 in the uncoupled position before the stop cam

00509 38, see Figure 3. 00510

00511 The key 8 in the form of a key card

00512 has its coding only on a partial area Fl.

00513 The remaining partial area Fl 'is locking code

00514 free of stanchions. The coded partial area Fl is a free space

00515 flanked edge 40 arranged upstream. From this goes

00516 a free space 41, which the locking coding

00517 upstream free area Fl '. As from Figure 2

00518 shows both the butt edge 40 and the

00519 free space 41 arranged in the middle of the key 8.

00520 Furthermore, the free space 41 is so far opposite the impact channel

00521 te 40 set back, what degree of set back

00522 the displacement stroke of the closing edge-operated closing

00523 works slide 15 corresponds. Furthermore, the width of the 00524 free space 41 that of the driver stop 44 des

00525 other locking mechanism slider adapted. 00526

00527 The other card-like key 9 is also in

00528 divided two sub-areas F2 and F2 '. The partial area

00529 F2 contains the locking mechanism slide 14

00530 effective locking coding. Your is a butt edge

00531 40 'upstream. The part that is free of locking erosion

00532 before F2 'is the back to the butt edge 40'

00533 sets range 42 assigned. The same applies here

00534 again that the abutting edge 40 'and free space 42

00535 sets are arranged. Furthermore, the back offset of the 00536 free space 42 is chosen so large that it

00537 stroke of the edge-operated locking mechanism slide 14

00538 corresponds. The free space 42 is then aligned with it

00539 insertion movement with the driver stop 43 of the

00540 locking mechanism slide 15, so that no entrainment this

00541 locking mechanism slide 15 when inserting the key 9

00542 takes place. 00543

00544 It can be seen from FIG. 2 that the one broad area of each

00545 key 8.9 is equipped with a label.

00546 This has the shape of a flat key. At the

00547 Insert the key, make sure that the 00548 number plate is recognizable by the user. This means

00549 ensures that the free spaces 41, 42 and butt edge

00550 40.40 'the key 8.9 is to take effect according to the regulations

00551 den. If necessary, a label can also be used

00552 that it is recognizable whether it is

00553 is the single or master key. 00554

00555

00556 The following mode of action occurs:

00557 When key 9 is inserted into insertion slot 7

00558 the key 9 passes between the guide plate 20 and 00559 arranges the anchor plate 21. In the inserted end position

00560 the closure coding of the partial area F2 the magnetic

00561 pins 19 of the gate valve 14 so that this

00562 leave the holes 17 of the locking plate 16. The the

00563 partial surface F2 upstream impact surface 40 '

00564 with further key insertion the driver stop 44

00565 of the locking mechanism slide 14, so that this goes hand in hand

00566 is advanced. The other locking mechanism slide 15

00567 stops. His driver stop 43 dives

00568 with this advance of the key 9 into the free

00569 conveys 42 which of the lock erosion-free

00570 partial area F2 'is arranged upstream. Due to the pre-publishers

00571 tion of the locking mechanism slide 14 is the relevant one

00572 taken half of the projection 26. The lead

00573 half acts on the tongue 30 and pivots it

00574 for the end of your grip. Taking the tongue 30 leads to

00575 of the position according to FIG. 4, wherein the tongue 30 the coupling

00576 moving sleeve 32 moves. It is in tooth

00577 reached on the one hand to the pinion 33 and on the other hand to the

00578 gear 36, so that a rotational displacement of the external

00579 handle leads to a pushing the mandrel 35. In

00580 the forward position of the locking mechanism slide 14th

00581 the stop cam 38 has stepped in front of the detent 39 ',

00582 so that the return spring 25 does not

00583 moved back over 14. This can only take place at

00584 willful withdrawal of the key 9. As soon as

00585 the key 9 the stop cam 38 supported by him

00586 happens, the latter can pivot while releasing the

00587 Relocation of the locking mechanism slide 14 in the

00588 initial position. 00589

00590 If key 8 is used, the lock

00591 encoding of the partial area Fl

00592 hitting magnetic pins 19 of the locking mechanism slide 15

00593 accomplished. Then takes place by means of the abutting edge 40 00594 the advancement of the locking mechanism slide 15 while

00595 the other locking mechanism slide 14 remains. It

00596 the driver stop 44 then enters the free space 41

00597 a. 00598

00599 In the second embodiment shown in FIG.

00600 game have the same parts with the same reference numbers. Reject

00601 accordingly, the locking mechanism slider 45,46 are designed

00602 such that the locking mechanism slide 45 a larger one

00603 has width as the locking mechanism slide 46. The

00604 Locking mechanism slide 45 of greater width takes

00605 otherwise two pairs of magnetic pin carriers 47, 48

00606, the magnetic pin carriers of each pair in tooth

00607 intervention to each other. The locking

00608 movement slider 45 by means of a key 49, the

00609 butt edge 50 in the area of the locking erosion-free

00610 partial area F2 'forms a free space 51. When inserted

00611 of the key 49 engages in this free space 51 of the

00612 slave stop 52 of the locking mechanism slide 46 a. The

00613 locking coding (partial area F2) of the key 49

00614 is accordingly with key 49 inserted

00615 in the area of overlap with the locking mechanism

00616 slider 45. The other key 53 has inserted into

00617 ter location in the overlap area with the

00618 slider 46 its closure coding partial area Fl

00619 on. Its upstream butt edge 50 'is a free space

00620 54 adjacent, in which when the key is inserted

00621 sels 53 the driver stop 55 of the locking mechanism slide

00622 bers 45 occurs. It is inserted when you insert one

00623 key either one or the other locking

00624 factory slider taken. 00625

00626 With regard to this embodiment, it is optionally provided that

00627 that when inserting a locking mechanism slide 45th

00628 actuating successor key a coding change 00629 tion takes place by the fact that the magnetic pen carrier

00630 ger 47.48 rotated. Then the predecessor key

00631 is no longer able to use the magnetic pins of this

00632 Locking mechanism slide 45 to be classified correctly.

00633 A clutch engagement is therefore impossible. 00634

00635 The third embodiment according to Figures 8 to 12 is

00636 realized with a mechanical • locking cylinder.

00637 This has a cup-shaped outer housing 56, which

00638 is closed by a rear end wall 57.

00639 An output element 58 is rotatably mounted centrally in this 00640. The output element 00641 58 forms a non-circular engagement cross-section 59 towards the inside of the pot.

00642

00643 An intermediate housing can be rotated in the outer housing 56

00644 60 stored. In this two are each a locking mechanism

00645 forming cylinder core sections 61 and 62 are present, 00646 which are designed from 00647 half cylinders abutting in a longitudinal division joint. A core drilling provided in the intermediate housing 60 serves to accommodate the half cylinder 00648.

00649 tion 63. The latter is longer than the cylinder core

00650 cuts 61.62. Each cylinder core section 61, 62 is

00651 with a set of tumbler core pins 64 or 65

00652 provided, which spring-loaded counter pins 66 and 67 of the

00653 intermediate housing 60 are assigned. On its inside

00654 each cylinder core section has 61.62 end

00655 a projection 68 or 69, which projections are for

00656 meshing cross section 59 of the output element 58

00657 zen. 00658

00659 In the basic position, the cylinder core section engages

00660 61 with a plug-in pin 61 'positive

00661 into a recess 70 of the intermediate housing 60,

00662 same figure 8. 00663 00664 The lock is actuated by means of two half keys 71, 72

00665 applicable. For each half key 71.72 each half key

00666 cylinder or cylinder core section 61, 62 a respective

00667 cut out key longitudinal guide 73 or 74. By

00668 different cross-sectional profiling is achieved

00669 that the corresponding half key only in its own

00670 key longitudinal guide can be inserted. 00671

00672 This results in the following mode of operation: Should the closing

00673 cylinder can be operated with the half key 71, so

00674 this is in the key longitudinal guide 73 of the cylinder

00675 core section 61. After successful entry

00676 are thrust by the one key

00677 shaft notches provided closing notches 75 the

00678 tumbler pins 64,66 arranged so that their separator

00679 ge at the level of the core bore 63. It can now

00680 half key 71 can be inserted further. Whose

00681 key tip is used to take the cylinder core

00682 cut 61, which is in relation to the other cylinder

00683 the core section 62 relocated. During this various

00684 exercise, the projection 68 is in driving connection to

00685 engagement cross section 59 of the output element 58, comparing

00686 before Figure 11. The cylinder core section can by means of

00687 of the key 71 can be rotated. The rotary movement of the 00688 cylinder core section 61 is transferred to the other

00689 ren cylinder core section 62 and thus on the intermediate

00690 housing 60. When the key 71 is removed again

00691 brought about the basic position. For example, the

00692 relocation of the relevant components

00693 be supported. 00694

00695 Figure 12 illustrates that the other key 72 in

00696 the cylinder core section 62 is inserted. The concerned

00697 end tumbler pins 65, 67 are arranged so that

00698 whose parting line at the level of the cylinder core bore 63 00699 lies. It can now advance a locking mechanism

00700 forming cylinder core section 62 take place under

00701 coupling of the output element 58. The classification of

00702 tumbler pins are made using the closing core

00703 ben 76 of the half key 72. From the presence of the

00704 locking notches 75, 76 of each half key 71 and 72, respectively

00705 cannot lock the other's code

00706 Determine key. This also applies if such

00707 ge locks are assigned to a master key system.

00708 Even from a large number of individual keys

00709 the locking code of the parent key

00710 cannot be derived. 00711

00712 According to the fourth exemplary embodiment

00713 also a mechanical lock in the form of a

00714 locking cylinder. This has a pot-shaped outer

00715 housing 78. In the rear end wall 79 and the

00716 pot bottom stores an output element 80.

00717 lying in the pot bore 81 two intermediate housings

00718 82, 83 arranged. These serve to accommodate locking

00719 works forming cylinder core sections 84,85, which in

00720 core bores 86,117 of the intermediate housing 82,83

00721 gen. In the cylinder core sections 84, 85 are together

00722 of the aligned key longitudinal guides 87.88 provided.

00723 Each cylinder core section 84.85 is with one set each

00724 of tumbler pins 89 and 90 provided which

00725 with counter pins 91, 92 of the intermediate housing 82 or 83

00726 interact. The counter pins are also 91.92 in

00727 direction of the core pins spring-loaded. 00728

00729 The key-insert-side cylinder core section 84

00730 can be operated with a key 93 of shorter length.

00731 Its shaft length corresponds to the length of the cylinder

00732 core section 84, compare FIG. 16. The intermediate

00733 housing 82 is rotatably mounted in the outer housing 78. As 00734 trigger protection serves a radially directed

00735 downward spring-loaded pin 94 of the intermediate housing

00736 82, which pin 94 into an inner ring groove 95 of the outer

00737 houses 78, compare in particular FIG. 14.

00738 This figure shows that the basic position of the

00739 intermediate housing 82 by a spring-loaded locking pin

00740 96 is secured, which is in an inside recess 97

00741 of the outer housing 78 immersed. A radial pin 98 of the

00742 cylinder core section 84 ensures that the cylinder 00743 core section 84 relative to its intermediate housing 82

00744 not rotatable, but only movable

00745 is. For this purpose, the intermediate housing 82 then forms

00746 the radial pin 98 a longitudinal groove 99. 00747

00748 The key-insert-side cylinder core section 84

00749 is rearward with a radially projecting wing 100

00750 equipped. This is used to move a transfer

00751 supply bar 101

00752 intermediate housing 83 arranged outer longitudinal groove 102. Der

00753 wing 100 is designed so that it when moving

00754 of the cylinder core section 84 in a form-fitting manner

00755 immersed outer longitudinal groove 102 and also the transmission

00756 ledge 101 in the direction of a radial locking wing

00757 103 of the cylinder core section 85 shifted. To this

00758 purpose the transmission bar 101 ends at a distance

00759 the locking wing 103, which in the locked position of the

00760 lock in a radial groove 104 of the outer

00761 house 78 lies. The radial groove 104 opens into one

00762 annular space 105 of the outer housing 78. A frustoconical

00763 ge compression spring 106 is supported on the pot bottom or front

00764 turned 79 and both applied to the blocking wing 103

00765 as well as the intermediate housing 83. This is the cylinder

00766 derkern section 85 and intermediate housing 83 existing,

00767 not locked by the tumbler pins

00768 rotatable in the outer housing 78. 00769 The transmission bar 101 is on the locking wing

00770 104 facing end with a radially inward-

00771 ten control cam 107 provided. This works together with

00772 a locking bolt guided radially in the intermediate housing 83

00773 108. A compression spring 109 loads it in outward direction.

00774 tung. There is a bifurcated configuration of the blocking

00775 gels 108 before, compare in particular Figure 15. Die

00776 fork legs 110 encompass transmission bar 101

00777 and enter the radial groove 104 of the outer

00778 house 78 a. The fork leg 111 limits the outward

00779 relocation of the locking bolt 108 and used to attack

00780 of the control cam 107 of the transmission bar 101. Im

00781 Contrary to the previous embodiment, the cylinder

00782 core section 85 in the basic position already in rotary

00783 driving connection to the output element 80 by the

00784 projection 112 of the cylinder core section 85 already around

00785 a certain dimension in the engagement cross section 113 of the

00786 driven elements 80 immersed. To release the cylinder

00787 core section 85 is used opposite key 93

00788 longer key 114. This is so long

00789 dimensioned so that it passes through the cylinder core section 84

00790 sets and in the axially adjoining cylinder core

00791 section 85 dips. On its narrow edge

00792 provided locking notches 115 are used to classify the

00793 tumbler pins. 00794

00795 According to this embodiment, the following effects result

00796 example:

00797 It is shown in FIG. 16 that the shorter one

00798 key 93 inserted into the cylinder core section 84

00799 ben. Through the locking notches 116 of this key

00800 93 the tumbler pins 89.91 are classified so that

00801 then the cylinder core section 84 opposite the

00802 intermediate housing 82 is displaceable in the inward direction.

00803 During this inward displacement, the wing 100 is immersed in 00804 the outer longitudinal groove 102 a producing a rotary

00805 binding to intermediate housing 83. At the same time

00806 the wing 100 the transmission bar 101 in axial direction

00807 movement postponed. The control cam 107 brings the locking

00808 gel 108 out of engagement with the outer housing 78. Furthermore

00809 through the transmission bar 101 of the locking wing 103 of the

00810 cylinder core section 85 relocated and thus also

00811 this. The tumblers 90.92 also cause one

00812 Take the intermediate housing 83. In this forward

00813 th position, the blocking wing 103 is in the ring

00814 space 105 of the outer housing 78. A rotary movement of the

00815 key 93 is accordingly on the wing 100 on the

00816 intermediate housing 83 and over the Zuhal- located there

00817 tion pins 90.92 on the cylinder core section 85

00818 transmitted, which takes the output element 80. 00819

00820 Using an auxiliary tool, only the

00821 cylinder core section 84 are rotated and thus also

00822 the intermediate housing 82. However, there is no rotary

00823 would take the intermediate housing 83. Will the opening tool

00824 into the key longitudinal guide 88 of the cylinder core

00825 section 85 is inserted, this cannot be

00826 hen due to the locking wing 103 and the locking bolt

00827 108. Even if there is an axial displacement of the intermediate

00828 housing 83 and cylinder core section 85 existing

00829 unit should take place, the locking bolt 108 remains

00830 still engaged with the outer case, which is a rotational movement

00831 blocked. 00832

00833 An actuation of the end is therefore only by means of

00834 of the longer key 114 possible. This

00835 penetrates the longitudinal key guide when it is inserted

00836 87 of the insert-side cylinder core section 84 and

00837 then dips into the longitudinal key guide 88 of the

00838 following cylinder core section 85. The keys- 00839 locking notches 115 on the shaft arrange the guard locking

00840 pins 90.92, so that a longitudinal displacement of the

00841 cylinder core section 85 through the key tip

00842 is enabled. With this longitudinal displacement the

00843 locking wing 103 of the cylinder core section 85 the radio

00844 alnut 104 and plunges into the annular space 105 of the outer housing

00845 ses 78, see Figure 17. It can then be used

00846 of the cylinder core section 85, the output element 80 00847 are rotated. The rotary motion is also transmitted

00848 if on the cylinder core section 84 and this

00849 assigned intermediate housing 82.00850

00851 After removing the key, the conical pressure

00852 spring 106 the relevant components in the basic position

00853 back. 00854

00855 It is possible to replace the intermediate housing 82

00856 by inserting a tool into the inner ring groove 95

00857 opening transverse bore 95 'of the outer housing 78 inserted

00858 becomes 94. 00859 while pushing back the pin
