Abstract

A lock is disclosed with a closing function released by inserting a card with magnetised areas. The lock has a bolt (11) with magnetic locking pins (14) that project into locking holes (13) arranged in the housing when the magnetic card is not in the lock, preventing the bolt from moving. When the right magnetic card is inserted into the lock, the magnetic locking pins (14) are pushed out of the locking holes (13) by the magnetic force and allow the bolt to be moved. The locking pins (14) lie in supporting recesses (18) of the bolt (11) so as to move transversely to the direction of displacement of the bolt. In order to increase safety against burglary, at least one supplementary locking pin (37) is mounted in the bolt (11). When no magnetic card is in the lock, the supplementary locking pin (37) lies outside of a supplementary locking hole (35) arranged in the housing. When a magnetic card that is not correctly magnetised in the area that corresponds to this supplementary locking pin (37) is inserted into the lock, the supplementary locking pin (37) enters the locking hole (35).

Description

00001 lock with by inserting an area

00002 magnetized key card to be released

00003 locking function

00004

00005 The invention relates to a lock with by insertion

00006 a key card magnetized in areas

00007 locking function, with a magnetic lock

00008 slide pins carrying slide pins, which tumbler pins

00009 if the key card is not inserted into the housing

00010 locking openings protrude and the slide displacement

Lock 00011 and which with the correct key inserted

00012 Seikarte according to magnetic repulsion to the key

00013 card step out of the blocking openings and the slide

Release 0001 overlap, the tumbler pins in

00015 bearing recesses of the slide can be moved

00016 slide displacement direction. 00017

A castle of the type in question is known from

00019 of WO 91/11582, the tumbler pins not

00020 inserted key card with one of the key

00021 self-insertion slot facing end into the locking opening

Protrude into it. After inserting the key card

00023, the magnetized areas

00024 moving pins so that they have the locking openings

00025 leave and the subsequent advance of the shooting

Allow bers. 00027

The object of the invention is based on the object

00029 en, a lock of the type in question in manufac

To design a technically simple way so that

00031 makes unauthorized opening difficult or burglar-proof

00032 is increased. 00033

On the one hand, the task of the invention is at least

00035 a supplementary tumbler pin mounted in the slide 00036 solved, which when the key card is not inserted

00037 outside of a housing-fixed addition assigned to it

00038 tongue lock opening and which when inserted,

00039 assigned to this supplementary tumbler pin

00040 Insert incorrectly magnetized key card in the

00041 blocking opening is moved into it. 00042

00043 According to such an embodiment, a generic

00044 lock according to increased security value specified.

The unauthorized opening of such a lock is

00046 considerably more difficult. While the tumbler pens

00047 according to magnetic repulsion to the key card

00048 shifted the locking openings assigned to them

00049, the supplementary tumbler pin is used by the

00050 corresponding place incorrectly magnetized key card

00051 te moved into the locking opening. So it's enough

00052 not knowing where the magnetic pins are and

00053 as they are polarized, but it should also be

00054, which of the supplementary

00055 are training pens. The right key card, which one

00056 is magnetized according to regulations in some areas,

00057 transfers the tumbler pins to the release position,

00058 during the supplementary tumbler pin in its release

00059 order persists and not in the supplementary blocking

00060 immersion. The slider is advanced

So 00061 can be performed. It is possible to use a lock

00062 made of ferromagnetic material anchor plate

Equip 00063, which the tumbler pins do not

00064 inserted key card in the blocking openings

00065 pulls in. Through this, preferably the insert

00066 slot adjacent anchor plate, the addition

00067 guard locking held in their release position. It

However, 00068 is also conceivable, a magnetized anchor plate

To use 00069 such that the tumbler pins on

00070 react repel and in the housing-side lock opening 00071 immersions during the supplementary tumbler

00072 pin is attracted to the magnetized anchor plate

00073 and accordingly not into the supplementary blocking opening

00074 protrudes. With the right key, the

Tension pins attracted to the release position while

00076 the supplementary tumbler pin in its release position

00077 lung remains. He leaves this when one is inserted

00078 improperly magnetized key card, through

00079 which according to the supplementary tumbler

00080 shear repulsion into the additional blocking opening

00081 drives and accordingly blocks the slide displacement. 00082

00083, on the other hand, solves the problem of the invention

00084 at least one opposite the blocking openings

Complementary blocking opening arranged fixed to the housing for

00086 Entry of at least one supplement stored in the slide

00087 tumbler pin proposed, which according to

00088 magnetic attraction to the key card outside the

00089 supplementary blocking opening is held. The barrier openings

00090 gen are thus on one side of the slide

00091 bers and the supplementary blocking opening on the opposite

00092 opposite side of the same. Is the right key card

00093 te inserted, so the tumbler pins

00094 magnetic repulsion to the key card in the release

00095 order brought to the barrier openings during the

00096 supplementary tumbler pen, however, according to magnetic

00097 attraction to the key card outside the supplement

00098 lock opening remains held. 00099

00100 Another solution is to use one of the

00101 blocking opening arranged in alignment opposite

To provide 00102 housing-fixed supplementary locking opening, the

00103 opening cross-section is smaller than the cross-section

00104 of the bearing recess, for the entry of a cross-sectional

00105 induced extension of a tumbler. Sam- 00106 blocking openings, the additions can

00107 tongue lock openings can be assigned. Also own

00108 the tumbler pins and the supplementary tumbler pins

00109 same design, what turns out to be manufacturing technology

00110 proves favorable. Depending on the installation of the magnetic pins,

00111 there is whether these as tumbler pens or

00112 should be used for tumbler pins. With deducted

00113 The tumbler pins protrude with their key card

00114 reduced section extension in the locking opening

00115, while the 180 ° to the tumbler pins

00116, used as a supplementary tumbler pin

00117 training pen with its extension opposite

00118 supplementary blocking opening, but not in this

00119 can dip into it. When inserting the

00120 gene key card are due to magnetic repulsion

00121 ßung the tumbler in the direction of the coaxial

00122 moved additional blocking openings arranged for them,

However, 00123 cannot because of their larger diameter

Immerse 00124 in this. This is only for the

00125 Additional tumbler pins possible when using a

00126 incorrectly magnetized key, then according to

00127 magnetic repulsion of the supplementary

00128 extension pins with their extension blocking in the

00129 Immerse the tongue lock opening. 00130

00131 Manufacturing and assembly technology, it is favorable that

00132 the housing-fixed locking openings of a locking plate

00133 are assigned, which lies in the liner to the

00134 slider and an anchor plate and which locking plate

00135 opposite the slide a the supplementary lock

00136 assigned additional locking plate assigned openings

00137 is. 00138

00139 The supplementary tumbler pin is arranged so that

00140 its reduced-section extension in the bloc 00141 kierposition of the slide in the locking opening

00142 protrudes, the correct key

00143 card moving the slide in the release position

00144 lung possible in that the locking opening in

00145 slide displacement direction a the cross section of the

00146 extension adapted escape slot connects.

00147 Due to magnetic attraction to the key card

00148 the extension then remains in the blocking opening and moves

00149 if the slide is moved forward into the alternative

00150 slot into it. A badly magnetized key card

00151 te, however, drives the magnetic repulsion

00152 supplementary tumbler pen in the associated

00153 tongue lock opening. 00154

00155 According to the invention it is possible that the supplement

00156 tongue tumbler pin a reduction in cross section on both sides

00157 decorated extension of the same diameter. Here-

00158 it is possible to use the supplementary tumbler (s)

00159 pens to be provided anywhere and above

00160 this also turned by 180 ° depending on the permutation

00161 position. 00162

00163 The fact that

00164 shows that the length of the supplementary tumbler pin is

00165 is greater than the thickness of the slide. The extension

00166 preferably corresponds to the thickness of a barrier plate

00167 te. 00168

00169 Finally, it should be emphasized that the locking opening

00170 is also smaller in diameter than the diameter

00171 ser the bearing recess. Therefore, a supplement

00172 Immerse the tumbler pin in the locking opening.

00173 This is only possible if by turning the

00174 supplementary tumbler pin this to the tumbler pin 00175 is such that the step-by-step

00176 set is opposite to the barrier opening. 00177

00178 Three exemplary embodiments of the invention are described below.

From Fig. 1 it can be seen that an inventive

00243 designed lock 1 on a door 2 -ex. a hotel-

00244 room door is set. The castle 1 has one 00245 lock case 3 arranged rectangular outside

00246 floor plan, which has an external covering at one end

00247 operation handle 4 stores. With their help, a

00248 case 5 are withdrawn. One on the inside

00249 the inner rotary handle 6 arranged against it is

00250 coupled directly to the trap 5, so that from this

00251 side of the door 2 can always be a door opening. 00252

00253 The lock case 3 is on the

00254 have 4 opposite ends with an insertion

00255 slot 7 for a magnetized key in some areas

00256 seikarte 8 provided. Regarding the magnetization points

00257 kte it can be surrounded by the key material

00258 ne permanent magnet plate 9 act. Further takes

00259 the lock case 3 a multi-part lock

00260 housing 10 on. In this is made of plastic

00261 tiger, plate-shaped slider 11 out.

00262 Whose upper broad side in Fig. 3 is on one

00263 brass-made locking plate 12, the immovable

00264 is held in the lock housing 10. The locking plate 12

00265 has locking openings 13, which in the in Fig. 3rd

00266 illustrated locking positions of the castle with

00267 bearing designs designed as through bores

00268 recesses 18 of the slide 11 are aligned. The latter are

00269 available in area distribution on the slide 11.

00270 In the bearing recesses 18 there are magnetic

00271 training pins 14 a. It is not necessary in everyone

00272 bearing recess 18 to provide a tumbler pin 14,

00273 because the number, location and polarity of the

00274 tumbler pins 14 after the respective opening

00275 code / combination of lock 1 aimed. 00276

00277 is on the other side of the locking plate 12

00278 a baffle 15 also made of brass, the

00279 an armature consisting of ferromagnetic material 00280 plate 16 is opposite. Compression springs 17

00281 pressed against the guide plate 15. Because of your

00282 the anchor plate 16 pulls the magnetic

00283 view tumbler pins 14, which consequently are in the

00284 Interlock openings 13 engage. In this situation, the

00285 slide 11 not illustrated in FIG.

00286 th basic position to be shifted because of the intervention

00287 of tumbler pins 14 in the locking plate fixed to the housing

00288 12 prevents this. It would be possible to be part of the

00289 bearing recesses 18 of the slide 11 in not moved

00290 vivid rotary bodies of the slide to provide

00291 a code change by turning this rotating body

To be able to make 00292. 00293

00294 The front transverse edges of both the anchor plate 16 and

00295 also of the guide plate 15 are in opposite directions

00296 angled and form a gusset for the

00297 key card to be inserted 8. The

00298 opposite broad areas of baffle

00299 15 and anchor plate 16 are the insertion slot 7. 00300

00301 A serving as a return spring 19 is on her

00302 one end fixed to a cross pin 20 fixed to the housing

00303 sets. The other end of the tension spring 19 engages on one

00304 according to FIG. 3 downward projection 21 of the

00305 slider 11, whereby this slider in the in Fig. 3

00306 stroke-limited basic position is moved. The pre

00307 jump 21 of the slide 11 is with a bevel 22nd

00308 provided, which on an obliquely angled rag

00309 23 a tongue 24 made of spring material

00310 picks up. A central recess 25 is the same

00311 penetrated by the projection 21. These spring

00312 material existing tongue 24 is on the insertion side

00313 clamped end of the lock housing 10. The command

00314 end of the spring tongue 24 opposite end 00315 26 is fork-shaped and engages in an annular groove

00316 27 an internally toothed coupling sleeve 28 a. According to

00317 the uncoupled position in Fig. 3 includes the clutch

00318 lungs sleeve 28 a pinion 29, which with a

00319 trigger mandrel 30 is non-rotatably coupled. It is the same

00320 rotatably connected to the inner turning handle 6. 00321

00322 The toothed pinion 29 is opposite a toothed wheel 31.

00323 Both the pinion 29 and the gear 31 are

00324 with the same toothing and the inner toothing

00325 adapted to the coupling sleeve 28. The gear 31 is

00326 for its part firmly connected to the external turning handle 4

00327 den. In the uncoupled position, the clutch

00328 lungs sleeve 28 exclusively the pinion 29 and

00329 is accordingly not in engagement with the gear 31.

00330 A rotational displacement of the external operating handle 4

00331 therefore leads to no entrainment of the pinion 29 and

00332 thus the presser mandrel 30. A the coupling sleeve 28

Compression spring 32 comprising 00333 loads the coupling sleeve 28

00334 in the direction of their home position. 00335

00336 On its narrow edges lying in the direction of displacement

00337 is the slide 11, each with a stop cam 33

00338 equipped. These work together with side spring

00339 cut 34 of the tongue 24, which spring sections 34

00340 form angled locking lugs 34 ', which in turn

00341 cooperate with the stop cam 33. 00342

00343 The configuration described above is all three

00344 jointly. 00345

00346 According to the first embodiment, in particular

3 to 6, the lower broad side of the

00348 slide 11 on a supplementary blocking openings 35-

00349 instructing additional locking plate 36. It is 00350 at least one such supplementary blocking openings 35 in

00351 of the additional locking plate 36 available. The supplements

00352 tongue lock opening 35 is aligned with one of the storage

00353 recesses 18.

00354 guidance pin 37 out. Its length corresponds to the

00355 thickness of the slide 11 and also the tumbler pins

00356 14. However, the locking plate 12 does not form a locking opening.

00357 tion for this supplementary tumbler pin 37. 00358

3 and 4 illustrate that in the basic position

00360 of the lock, that is with the slider 11 moved back,

00361 only the tumbler pins 14 the blocking

Take over 00362. The supplementary

00363 tumbler pin 37 towards the bottom of the locking

00364 plate 12 drawn. Due to the nature of the material

00365 of the same there is a certain magnetic transparency

00366 renz, so that it is ensured that the supplementary

00367 training pin 37 not in the supplementary locking opening 35

00368 dips. 00369

00370 If the key card 8 with the

00371 le located magnetic plate 9 inserted, see above

00372 results in the position in the inserted end position

00373 according to FIG. 5. The poles facing the locking plate 12

00374 of the tumbler pins 14 have the same poles of the magnetic

00375 plate 9 opposite, so that according to magnetic

00376 repulsion the tumbler pins 14 the locking openings 13

00377 leave the locking plate 12. That of the locking plate 12

00378 facing north pole of the supplementary tumbler pin 37

00379, however, is a south pole of the magnetic plate 9

00380 above, so that due to magnetic attraction to the key

00381 seikarte the supplementary tumbler pin 37 outside the

00382 supplementary blocking opening 35 is held. Because of

00383 of which is a forward displacement of the slide 11 by means of

00384 of the key card 8 possible, which with it 00385 insert-side end edge against a driver

00386 blow 38 of the slider 11 bumps. The advance

00387 of the slide 11 happens against the force of the

00388 tension spring 19. It should also be mentioned that during the

00389 inserting the key card 8 into the

00390 slot 7 the anchor plate 16 against the force of

00391 compression springs 17 was shifted. Along with the

00392 advance of the slide 11 is by the

00393 bevel 22 the spring tongue 24 around its clamping

00394 en pivoted. Since the free, forked end 26 of the

00395 spring tongue 24 in engagement with the coupling sleeve 28

00396 stands, this is shifted so that it then

00397 also overlaps the gear 31. Now that both gears

00398 29, 31 are encompassed by the coupling sleeve 28

00399 operated the lock 1 by means of the external turning handle 4

00400. Also have in the forward position

00401 the locking lugs 34 'the stop cam 33 of the slide

00402 11 and hold it in the forward

00403 th position. Only when the key card 8 is withdrawn

00404, the slide 11 returns to its starting position

00405 back. 00406

00407 If an incorrectly magnetized key card 8 ', such as

00408 FIG. 6 illustrates it, in the insertion slot 7

00409 inserted, for example, all holdings

00410 guide pins 14 are shifted into the release position

00411 den. However, if this also applies to the supplementary tumbler

00412 pin 37 associated magnetic plate 9 on repelling

00413 acts, the supplementary tumbler pin 37 plunges into the

00414 additional lock recess 35 of the additional lock plate

00415 36 and blocks a shift of the slide

00416 bers 11. It is therefore not enough just to know where the

00417 magnetic tumbler pins and how they

00418, but it should also be fixed

00419 which of the magnetic tumbler pins 00420 te the supplementary tumbler pins 37 are.

00421 An unauthorized opening of the lock 1 is thus elevated

00422 difficult.

00423

00424 According to the second embodiment, shown in FIGS

00425 FIGS. 7 to 10, the same components have the same reference

00426 digits. The locking openings 13 'of the locking plate 12'

00427 are opposite supplementary blocking openings 35 '. On

00428 part of the bearing recesses 18 takes magnetic Zuhal¬

00429 training pins 14. The diameter of the bearing

00430 recesses 18 is larger than the diameter of the

00431 additional blocking openings 35 '. In at least one of the

00432 bearing recesses 18 is a supplementary tumbler pin

00 433 39 out. This has a reduced cross-section on both sides

00434 decorated extensions 40, 41 of the same diameter. The

00435 length of each extension 40, 41 corresponds to the thickness of the

00436 locking plate 12 'or the additional locking plate 36'.

00437 Furthermore, the length of the supplementary tumbler pin 39

00438 greater than the thickness of the slider 11. The total length

00439 of the supplementary tumbler pin 39 corresponds to the thickness

00440 of the slide 11 plus the length of an extension 40

00441 or 41.

00442

00443 Furthermore, FIGS. 7 to 10 illustrate that the

00444 locking opening 13 'in the slide displacement direction

00445 the cross section of the extension 40 adapted evasive

00446 slot 42 connects. Its length is so large

00447 sen that the slider 11 in its unobstructed

00448 advanced end position can be moved.

00449

00450 It would be possible to use only the supplementary supplement

00451 training pin 39 an additional locking recess 35 "zu¬

Arrange 00452. However, since all locking recesses 13 '

00453 opposite supplementary recesses 35 'zuge¬

00454, can be changed without changing the locking plates 12 ', 00455 36 'the equipment with the tumbler pins 14 and

00456 supplementary tumbler pins 39 are made,

00457 the latter also in the inverted position for

00458 set can arrive. 00459

00460 If the correct key card 8 is not inserted,

00461 enter the tumbler pins 14 in the assigned

00462 th locking openings 13 'of the locking plate 12'. This

00463 also applies to the supplementary tumbler pin 39, which with

00464 its extension 40 into the associated lockout

00465 recess 13 'protrudes. If the right key 8

00466 inserted, the magnetic tumbler pins are

00467 te 14 due to magnetic repulsion to the key 8

00468 out of the locking openings 13 'of the locking plate 12'

00469 relocated. Due to magnetic attraction remains

00470 however the supplementary tumbler pin 39 in the positive

00471 on, in which the extension 40 in the assigned to it

00472 locking opening 13 'protrudes. It is still a pre

00473 displacement of the slide 11 possible, the continued

00474 set 40 passes through the alternative slot 42. 00475

00476 A wrongly magnetized key 8 ', see Fig. 9,

00477 can indeed all tumbler pins 14 in the release

00478 shift position. This key card 8 'also works

00479 repelling on the supplementary tumbler pin 39, see above

00480 engages its extension 41 in the supplementary lock opening

00481 35 'of the supplementary locking plate 36' and blocks that

00482 Advance the slide 11. Again

00483 um that the polarization and location is not enough

00484 of the magnetic pins, but it is also important to

00485 some magnetic pins to find out that

00486 holding pins serve so that unauthorized opening of the

00487 castle is extremely difficult. 00488 00489 Also in the case shown in FIGS. 11 to 13

00490 clear third embodiment of the same components

00491 same reference numbers. The locking openings 13 ''

00492 Locking plate 12 '' are in line with each other

00493 Additional locking openings 35 '' of the additional locking plate

00494 36 '' arranged. The opening cross-section or diameter

00495 ser of these additional blocking openings 35 '' is smaller

00496 as the diameter of the bearing recesses 18 of the slide

00497 bers 11. The locking openings 13 '' are also through

00498 smaller than the diameter of the bearing recesses

00499 18 and in diameter that of the supplementary

00500 locking recesses 35 '' adapted. 00501

00502 The tumbler pins 14 'are now opposite the two

00503 above-described embodiments modified

00504 det. The change is that every

00505 tion pin 14 'a reduced-section extension

00506 43 has 13 '' for entry into the blocking opening. The

00507 length of extension 43 corresponds to the thickness of the barrier

00508 plate 12 '' or that of the supplementary locking plate

00509 36 ''. The tumbler pins 14 'are

00510 plate 16 tightened, with its extension 43 in

00511 and immerse the respective blocking opening 13 ''

00512 block the slide 11. 00513

00514 If the tumbler pin 14 'is turned through 180 ° and set

00515 this in a bearing recess 18 is obtained

00516 this way a supplementary tumbler pin 14 ''.

00517 The anchor plate 16 is used when the anchor plate 16 is not

00518 inserted key card in the release position to him

00519 assigned additional blocking opening 35 '',

00520 see Fig. 11. If the correctly magnetized key

00521 8 is inserted according to FIG. 12, leave the

00522 tungsstifte 14 'due to magnetic repulsion to

00523 key 8 the locking openings 13 '' of the locking plate 00524 12 ''. In contrast, the supplementary tumbler pin 14 ''

00525 due to magnetic attraction by the key 8 in

00526 the release position held so that the pre-publishers

00527 tion of the slide 11 is possible. 00528

00529 A wrongly magnetized key 8 'leads against it

00530 for the position according to FIG. 13, with the tumbler pins

00531 14 'step out of their blocking position. This

However, 00532 does not meet the supplementary tumbler pen

00533 14 '', which due to magnetic repulsion

00534 with its extension 43 in the supplementary blocking

00535 immersion 35 '' of the additional locking plate 36 ''.

00536 The forward movement of the slide 11 is thus prevented.

00537 changes. 00538

00539 With this last version it would be possible to exclude

00540 lent to the 14 '' supplementary tumbler pins

00541 equipped with additional locking recesses 35 ''

00542 to be provided. However, the comparison of the

00543 tongue locking openings 35 '' to all locking openings 13 ''

00544 the possibility of optionally equipping the slide

00545 bers 11 with tumbler pins 14 'and supplementary tumbler

00546 tungsstifte 14 * ', the latter only by turning

00547 of the tumbler pins 14 'to this supplementary tumbler

00548 pins 14 ''. 00549
