Abstract

The invention concerns a lock (1) opened by the insertion of a partially magnetized code card (8) and proposes, in order to produce a particularly user-friendly design, that a store (S) be fitted which is initiated in the lock-release position and which can be deactivated without neutralizing the lock-closure function and which, in use, stores, in such a way that the store can be interrogated, card code data in relation to other, absolute, data such as date and time of insertion of the card for a multiplicity of card insertions.

Description

00002 lock with a magnetic

00003-based key card to release the locking function

00004

00005 The invention relates to a lock with by insertion

00006 to release a magnetized key card

00007 giving locking function, in which the key card

00008 a released by the magnetic tumbler pins

00009 dragged a slide. 00010

The known locks of the aforementioned type are in the

00012 constructed in such a way that it has a magnetic tumbler

Have 00013 pusher slider. For accommodation

00014 of the tumbler pins are in the slide bearing

00015 provided, the tumbler pins with a

00016 according to the polarized key card

00017 ken. By inserting the correct key card

00018 te leave the magnetic tumbler pins

00019 locking plate, so that by means of the key card

00020 slide displacement can be made. 00021

The object of the invention is based on the object

00023 in a lock of the type in question in manufac

Lung technically simple way the utility value of

00025 lock through a supplementary user function

Increase 00026. 00027

00028 The task of the invention is solved by the

00029 award 1 specified invention. 00030

00031 The subclaims represent advantageous developments

00032 of the inventive solution. 00033

According to such a design is a castle in

00035 type created, which is supplemented by a 00036 use function an increased utility value

00037, characterized in that part of the magnetic areas

00038 before the key in the release division of the slide

00039 causes a memory arranged in the lock to store data,

00040 preferably the date and time of the key entry

00041 push time, available to be saved, on the other hand

00042 the user of the lock does not know whether this

00043 is now (currently) functioning or not. The

00044 memory can then be stored for a plurality of key

00045 push times, e.g. twenty. In the

00046 the key card to be inserted thus points

00047 not only the opening coordinated to the lock

00048 code combination containing magnetized area

00049, but also has another magnetized

00050 section for initiating the arranged in the castle

00051 date / time memory. To be particularly advantageous

00052 it turns out that this additional control

00053 function of the key card is not recognizable. The

Part of key initiating 00054 is optical

00055 indistinguishable from the closure area, and he

00056 does not affect the locking function of the lock,

00057 so that the sub-area mentioned in several, the same

00058 key cards having an opening code combination

00059 can be magnetized differently. He's also

00060 not to locate without knowing the inside of the

00061 castle. A sub-area of the magnetic

Key points keyed a personal user code

Embody 00063, who then also stores in memory who

00064 from a number of authorized persons to one

00065 has closed the specified time. When the memory

00066 chers this will then e.g. issued as a digit.

00067 This is advantageous, for example, in hotel room

00068 locks, the key cards of the hotel staff

00069 in addition a different magnetized section than

Have 00070 user code as the master key. Also 00071 there is the possibility of

00072 would be without such a magnetized portion

00073 provided. The memory can be in the form of a

00074 se arranged chips can be formed, the date / time

00075 contains time and each time a certain number of

00076 assigned to individual data stores in such a way that

00077 exceed a maximum number of individual data

00078 first data deleted and replaced with new one

00079. With a maximum storage of for example

00080 se twenty individual dates are thus date, time and

00081 possibly user code of the last twenty key

00082 saved times, provided the key cards

00083 with a magnetized which causes the memory

00084 are provided. The stored in the chip

00085 individual data are available. For example

Be realized in that the chip of the lock with

00087 is connected to a computer unit or can be brought

00088, which evaluates the individual data. Alternatively

00089 it is also possible to transfer the data directly to the lock

00090 to get an interface. This can also be done after

00091 me of memory and then only then and possibly

00092 happen elsewhere, e.g. as a service of

00093 locking system suppliers. This has technical aspects

00094 advantages e.g. B. in that after a theft in

00095 taken from a hotel room the store and unchanged

00096 can be checked / accessed under objective supervision

00097 can. In principle, the memory can only be queried

00098 for a limited group of people. Everyone

00099 Incorrect key insertion is not saved

00100 rather held because a wrong key prevented the

00101 can not bring in release department. The command

00102 to the memory for storing can by means of the lock

00103 sensors arranged in the housing, e.g. Hall probes and / or

00104 induction coils are made. By inserting one with

00105 a key card provided with a magnetized partial area 00106 te are then induction voltages in the induction coils

00107 gene generated, which are evaluated by the chip.

00108 Then possibly because of this self-sufficiency

00109 Battery for the memory / reader is not required. Advantageous-

00110 the invention can also with recodable locks

00111 ser can be applied. Here is a succession key

00112 is such in the area of its opening code combination

00113 magnetises that after the same has been inserted, the combination

00114 tion of the lock is adjusted so that the previously

00115 valid guest key card no longer the valid one

00116 opening code combination. Such an

00117 staltung is for example from DE-OS 37 28 072

00118 known. The guests' key cards could also be found here

00119 with a magnetized initiating the memory

00120 partial area, which in addition to the

00121 also called the key card number

00122 can be saved. It is therefore a castle with one

00123 increased security value created. Alternatively, the

00124 arrangement can also be made so that the slide

00125 and / or the switch requesting the key card

00126 hen, the forward position of the slide

00127 puts the memory into effect accordingly. The memory

00128 can be powered by a battery located in the lock

00129 be or embody a structural unit with this. In

00130 connection with the query of the data via an interface

00131 place directly in the lock housing has the arrangement of

00132 battery in the lock in particular the advantage that

00133 lock can be easily attached to a door

00134 can without wiring to supply the

00135 memory and for querying the data

00136 must. It is therefore also possible to use commercially available card

00137 Exchange locks for card locks, the one

00138 have control function according to the invention or last

00139 re to bring in generic locks. 00141 The locks can also have a free space for the

00142 corresponding control unit to be delivered to the

00143 associated hardware (memory, reader, battery etc.)

00144 to be installed afterwards. The free space can e.g. B. also from

00145 be formed an additional part, for. B. one such

00146 which is designed as an angle. The one Winkelsche

00147 kel extends parallel to the screw surface and

00148 may be used for attachment. The other Winkelsche

00149 kel protrudes over the top of the lock to the

00150 sel card insertion slot, - so that the key card

00151 when inserting in front of the front end of the angle

00152 kels moved past to be read, what for

00153 upper leg the corresponding hardware (memory,

00154 battery, reading device, etc.) are housed

00155 or can be. 00156

00191 is a lock designed according to the invention

00192 1 on a door 2 - for example a hotel room door -

00193 set. The lock 1 has an outside of the door

00194 arranged lock case 3 rectangular floor plan,

00195 which has an operating handle 4 at one end

00196 stores. With their help, a trap 5 can be withdrawn

00197. One arranged on the inside of door 2

00198 internal turning handle 6, however, is directly with the latch 5

00199 connected so that from this side of the door 2 always

00200 a door can be opened. 00201

00202 The lock case 3 is on the actuation handle 4th

00203 opposite end with an insertion slot 7 for

00204 a key card 8 areas magnetized in sections

00205 hen, with a magnetized area C the opening

00206 code combination includes and a second section

00207 I for initiating a memory arranged in castle 1

00208 chers S. serves. Furthermore, the lock case 3 takes up

00209 lock set 9. The latter has a bottom part 00210 10, a middle part 11 and a cover part 12. The half

00211 shell-like bottom part 10 is in the middle part

00212 11 entering screws 13 connected to this. This

00213 two aforementioned parts 10 and 11 are previously together

00214 plugged, being from the central part 11 in the direction of

00215 bottom part 10 directed centering feet 14 that

00216 in niches 15 provided for this purpose in the base part 10

00217 grab. The screws 13 also serve to fix

00218 of the cover part 12. From this go into card settings

00219 corner direction extending housing side walls 17, the

00220 at the card insertion end with inward facing

00221 support tab 18 are provided, in which the screws 13th

Intervene 00222. The one opposite the insertion slot 7

00223 end of the cover part 12 has a tongue 19 which at

00224 pushing the cover part 12 onto the middle part 11 in

00225 a recess 20 of a dome 21 of the middle part 11

00226 engages. Furthermore, a rear grip is achieved on the

00227 tongue 19 opposite end of the side walls 17,

00228 why hook-shaped projections 22 and 23 from the middle

00229 overlap part 11 and cover part 12. 00230

00231 The bottom part 10 and the middle part 11 are on the

00232 insertion slot 7 facing away from the end

00233 two further screws 24 combined into one unit

00234 adds. While for the bottom part 10 and middle part 11

00235 aluminum is used, the cover part 12 consists of

00236 plastic. Between the cover part 12 and the middle

00237 part 11 is also made of plastic,

00238 slider 25 designed plate-shaped. With its

00239 ner a broad side, the slide 25 is on the Mit-

00240 part 11 on. The opposite guide surface

00241 forms a locking plate 26 made of brass, the

00242 inserted in the cover part 12 and there with the side

00243 above sections is immovably set.

00244 The holes 29 of the locking plate 26 are aligned in the in FIG. 00245 10 shown locking position of the lock 1 with

00246 formed as a through hole bearing recesses

00247 30 of the slide 25. Lie in the bearing recesses 30

00248 magnetic tumbler pins 31 a. It’s not necessary

00249 dig, a tumbler pin in each bearing recess 30

00250 31 to be provided because the number, the location and the

00251 polarity of tumbler pins 31 according to the respective

00252 opening code combination of lock 1 aimed. In particular,

00253 in particular that of the initiation area I of the key card

00254 te 8 assigned area of the slide 25 is not with

00255 tumbler pins 31 provided. 00256

00257 is on the other side of the locking plate 26

00258 a guide plate 32 also made of brass, the

00259 an anchor plate 33 is opposite. The latter is from

00260 three compression springs 34 held in position. The

00261 aforementioned compression springs 34 are based in turn

00262 the cover part 12. 00263

00264 The anchor plate 33 is in contrast to the others

00265 components made of ferromagnetic material. Hence

00266 the anchor plate 33 pulls the magnetic tumbler

00267 te 31, which consequently in the holes 29 of the locking plate

Intervene 00268 te 26. In this position, the slide 25

00269 not from its basic position illustrated in FIG.

00270 lung be shifted because the engagement of the tumbler

00271 pins 31 in the housing-fixed locking plate 26 this prevents

00272 different. It would be possible to have some of the bearing recesses

00273 30 of the slide 25 in rotating bodies (not illustrated)

00274 pern of the slider to provide a code change

00275 by turning this rotating body. 00276

00277 Both the anchor plate 33 and the guide plate 32

00278 close the insertion slot 7 of the lock box

00279 at least 3. Their front transverse edges 32 ', 33' are in 00280 angled opposite directions and form one

00281 Gusset for the key card to be inserted 8

00282 represent the opposite broad areas of

00283 guide plate 32 and anchor plate 33 the key card

00284 drawer 35 represents 00285

00286 A serving as a return spring 36 is with her

00287 one end on a cross pin 37 of the middle part 11

00288 set. This cross pin 37 goes from the

00289 over 25 opposite side of the middle part 11

00290 and protrudes into the interior of the bottom part 10. The other

00291 end of the tension spring 36 engages in a slot 38

00292 of the middle part 11 penetrating projection 39 of the slide

00293 bers 25, which means that this is limited to a stroke

00294 basic position is moved. The projection 39 are also

00295 two bevelled lugs 40, 41 of the slide 25 in front of

00296 gert, which also like the projection 39, the middle part

00297 11 reach through. The bevels 40 ', 41' of the lugs

00298 40.41 are designed in the same direction. They are attacking

00299 obliquely angled tab 42,43 of a web 44 one

00300 made of spring material tongue 45. A medium one

00301 recess 46 of the same is penetrated by the nose 40

00302 sets. 00303

00304 The insertion end of the spring tongue 45 extends

00305 between the middle part 11 and the bottom part 10 and

00306 is fixed there by means of the screws 13, the through

00307 reach through the openings of the spring tongue 45. 00308

00309 The opposite end of the spring tongue 45

00310 end 48 is fork-shaped and engages

00311 an annular groove 49 of an internally toothed coupling sleeve 50

00312 a. According to the decoupled position in Fig. 10 includes

00313 the coupling sleeve 50 a pinion 51, which with

00314 a cross-sectionally larger collar 52 in a bearing opening 00315 53 of the bottom part 10 is arranged. In the federal government 52

00316 there is a diametrical slot 54 in which a

00317 end 55 of a trigger mandrel designed like a hammer head

00318 56 dips. It is non-rotatable with the internal

00319 handle 6 connected. 00320

00321 The pinion 51 is a gear 57 opposite. Either

00322 the pinion 51 and the gear 57 are in their

00323 toothing designed the same and the internal toothing of the

00324 coupling sleeve 50 adapted. The gear 57 in turn

00325 is firmly connected to the external turning handle 4. to

00326 position stabilization of the gears 51,57 is used by

00327 pinion 51 outgoing centering pin 51 ', which in

00328 a cross-sectional blind bore 57 'of the gear

00329 57 immersed. The same extends within the

00330 Domes 21 of the middle part 11 and lies there with a

00331 cross-sectionally larger collar 57 '' in a bearing cavity 58

00332 of the dome 21 a. Included in the uncoupled position

00333 the coupling sleeve 50 exclusively the pinion 51st

00334 and is accordingly not in engagement with the gear 57.

00335 A rotation shift of the external turning handle 4 therefore leads

00336 to take away the pinion 51 and thus the

00337 presser mandrel 56. So that the coupling sleeve 50 its basic

00338 position does not leave unintentionally, is the clutch

00339 sleeve 50 comprehensive compression spring D provided

00340 supports one end on the inside of the cathedral 21 and

00341 on the other hand a collar 50 'of the coupling sleeve 50

00342 beats. 00343

00344 On its narrow edges lying in the direction of displacement

00345, the slider 25 is each equipped with a stop cam 59

00346 pieces. These work together with side spring

00347 cut 60 of tongue 45, which spring sections 60

00348 with detents 60 'interact with the stop cams 59

00349 ken. 00350 is between the key card 8 and the slider 25

00351 a positive coupling can be produced. That is educated

00352 form-locking coupling of a in a bore 61 of the

00353 slide 25 mounted pin 62. The bore 61 is

00354 detects itself at the mouth end of the key card

00355 slot 35. The two ends 63, 64 of the pin

00356 tes 62 are conical. The total length of the

00357 pin 62 is greater than the thickness of the slider 25.

00358 The conical end 64 facing the middle part 11

00359 engages in the return position of the slide

00360 25 in a frustoconical recess 65 of the lock

00361 housing or the middle part 11. The depth of this

00362 recess 65 is less than the height of the conical

00363 genes 64. In this final relocation position

00364 the other conical end 63 is above the other

00365 wide area of the slide 25 in front and protrudes in the key

00366 sel card slot 35 in such a way that the

00367 tapered end 63 with penetration of a longitudinal slide

00368 zes 66 of the guide plate 32 on the anchor plate 33

00369 supports. The pin 62 acts together with a recess

00370 67 of the key card 8. 00371

00372 In the area facing the tongue 19 there is a chip 68 serving as a memory S in the middle of the cover part 12

00374 arranged. The latter is in the lock case 3

00375 arranged but not shown battery

00376 feeds. In the exemplary embodiment shown, the

00377 chip 68, viewed in the direction of displacement of the slide 25

00378 hen, two induction coils 69,70 upstream, which in

00379 connection with the chip 68. The arrangement is

00380 taken so that the induction coils 69.70

00381 outside the area of the ferromagnetic armature plate

00382 te 33 lie. 00383 00384 The following mode of action occurs: Should that

00385 lock 1 from the outside by means of the external

00386 handle 4 are operated, it is necessary to

00387 with which the corresponding opening code combination is

00388 facing area C provided key card 8 in the

00389 insert slot 7. It shifts the

00390 by the compression springs 34 anchor plate 33 in

00391 cross direction. In the fully retracted position

00392 occurs the key card 8 with its insert side

00393 end edge 8 'in front of one in the direction of the cover part 12

00394 pointing slide stop 25 *. Are in this position

00395 the magnetic tumbler pins 31 by means of the opening

00396 code combination area C of the key card 8

00397 shifted so that it holes 29 of the locking plate

00398 26 leave. Furthermore, the key card

00399 ten-slot 35 facing end 63 of the pin 62nd

00400 with the recess 67 of the key card 8. It can now

00401 the further movement of the key card 8 take place, wherein

00402 the slide 25 counter to the force of the tension spring 36

00403 is being towed. During this shift, the

00404 recess 65 in connection with the conical end

00405 64 a control of the pin 62 such that this

00406 as illustrated in FIG. 11, in the recess 67 of FIG

00407 key card 8 dipped. In the previous position

00408 lung have the locking lugs 60 'of the spring sections 60

00409 attack cam 59 of the slider 25 behind and

00410 keep it in the forward position. Accompanying

00411 with the advance of the slide 25 was through

00412 the bevel 40 'of the nose 40 of the web 44 is applied

00413 and the spring tongue 45 around their clamping points

00414 swiveled. Because the free, forked end 48 of the tongue

00415 45 is in engagement with the coupling sleeve 50 is

00416 these moved so that they then the gear

00417 57 overlaps. Since both gears 51, 57 from the

00418 coupling sleeve 50 are included, can by means of the outer 00419 rotary handle 4 the lock 1 are operated. In the forward position illustrated in 00420 Fig. 11 occurs

00421 the initiation area I of the key card 8 in the

00422 area of the induction coils 69.70, so that by the

00423 changes caused by this, for example the

00424 magnetic field, induction voltages in the induction

00425 len 69.70 are generated. These induction voltages

00426 cause data to be saved, in particular

00427 of date and time and possibly user code in

00428 memory S. Instead of the induction coils you can also

00429 other sensors, e.g. Hall sensors, which are also several

00430 address magnetic single points of the key,

00431 Find use. It is particularly advantageous here

00432 that the slide 25 must first be advanced,

00433 to realize an initiation of the memory S.

00434 key cards 8 with one not on the lock 1

00435 agree opening code combination area C.

00436 therefore no storage of data. It will only

00437 registered when the key card 8 in the lock 1

00438 has been shifted so far that an unlocking of

00439 door could take place anyway. Here, the

00440 Registration of twenty individual data, for example

00441 in such a way that when this number of pieces is exceeded

00442 the first data is deleted and replaced by the new one

00443 data to be replaced. Querying the saved

00444 Data can be sent via an interface, not shown

00445 and / or by removing the memory

00446 or only after removal. He can also against

00447 an unused be replaced. 00448

00449 The arrangement can be such that induction coils

00450 len 69.70 in the area of the key box slide-in chess

00451 tes 35 are provided. According to this arrangement

00452 is also the initiation area I on the

00453 key card positioned. Whose magnetic field is coming 00454 then also the further function of the on-switching

00455 ens (cause) the memory to. Just to

Register 00456 when unlocking the lock has 1

00457 can also take place a switch in which the

00458 insertion slot 7 opposite area of the lock case

00459 be arranged at least 3, which is only in the case of advance

00460 position of the slide 25 the memory S for data

00461 storage initiated. 00462

00463 When you remove the key card 8 is inevitable

00464 via the pin 62 that has entered the key card 8

00465 the slide 25 is in the return position

00466 moves. It is in alignment with the recess

00467 65 and thus allows the complete removal of the

00468 key card 8. During the card withdrawal movement

00469 also the rest between the stop cams 59 and

00470 locking lugs 60 'of the spring tongue 45 overcome such that

00471 the starting position is present again. Also was

00472 the coupling sleeve moved back in that the

00473 another nose 41 with its inclined surface 41 'the tab 43

00474 of the web 44 and thus also the spring tongue

00475 45 returns to its end position. 00476

00477 It is also possible to store the time of the

00478 key deduction to register to if necessary

00479 even record the insertion time of a key. 00480

00481 There is also the option of

00482 marked key insert subsequent opening actuation

00483 the handle 4 in the memory according to the time etc.

00484 gen, e.g. by querying the movement of the mandrel 56 over

00485 a switching disk Seh, all according to EP-A 1,364,878.

00486 That would also have the advantage that a door inside

00487 lock operation (without key use) 00488 is removed because the memory is not

00489 th slide is activated. 00490
