Abstract

A locking system is composed of a lock and several keys. Closure of the lock is determined by magnetically controlled tumblers and it can be modified so as to respond to the code of a subsequent key by displacement of at least one tumbler element within the lock. In order to obtain a particularly reliable and advantageous design, the tumbler element (33, 33') is designed as an adjusting element associated to the code conversion magnets (42, 43, 44, 45, 46, 48, 49), so that the tumbler insertion opening (40, 50, 51) for the code conversion magnet can be moved out of alignment with the code conversion magnet.

Description

00001 Lock consisting of lock and several keys

00002 system. 00003

The invention relates to a lock and several

00005 Keys existing locking system, in which the

00006 determined by magnetically controllable tumblers

00007 closure of the lock can be changed such that the

00008 first correspond to the coding of the first key

00009 en Lock code of the lock due to relocation

00010 most of a tumbler within the castle

00011 can be changed to encode a successor key

00012 sels, the coding of individual permanent magnet

00013 ten is formed, which is inserted in openings of a slide

00014 arranges and by means of appropriately positioned magnet

Areas of adjustment one in parallel to the slide

00016 bringable key can be raised to a locking plate

Are after which the slide in a lock-open position

00018 is displaceable, with some of the permanent magnets as

00019 recoding magnet is provided. 00020

In a known castle of the type in question

00022 the slider takes rotatably assigned, mutually

00023 the meshing carrier, each with

00024 are equipped with a recoding magnet. It is there

00025 such a measure is taken that by means of the successor

00026 closed the carrier with the transcoding magnet

00027 can be moved by changing the locking code. The

This saves 00028 the first key. 00029

The object of the invention is to create a generic

00031 moderate castle in a simple manner so that

00032 the ^• variation options for changing the locking

00033 codes are increased. 00034 This task is solved at a castle in question

00036 standing type in that the tumbler as that

00037 recoding magnet associated adjusting part designed

00038 is such that the tumbler entry opening for the

00039 recoding magnets from the aligned position to the recoding

00040 dierungs agneten is relocatable. 00041

According to such an embodiment there is an increased

00043 possible variation to change the locking code.

00044 to change the locking code does not need the

00045 recoding magnet from one position to another

00046 position to be brought. Rather, this is what is happening

00047 by changing the position of the recoding magnet

00048 arranged, as an adjustment part tumbler

00049 des. Along with a shift in the adjustment

00050 also partially reaches its tumbler entry opening

00051 for the recoding magnet from the aligned position

00052 this. If the guard locking is aligned

00053 entry opening to the recoding magnet such

00054 key inserted, which prevents the transcoding

00055 magnets in the direction of the tumbler entry opening

00056 causes, the slide is not advanced. Whose

So 00057 shift requires a key that is in the

00058 corresponding area is magnetized so that it

00059 recoding magnet attracts so that it does not enter the

00060 tumbler entry opening is immersed. On this basis

00061 the most different versions can be realized. 00062

00063 A variant is characterized in that a

00064 part several in diameter and / or depth

00065 has different tumbler entry openings. Who-

00066, for example, of different sizes in diameter

00067 guard locking entry openings are selected, then a

00068 recoding magnet caused by the

00069 correspondingly magnetized key, only then possible. 00070 if the tumbler entry opening in diameter

00071 is the same size or larger than the relevant recoding

00072 magnet. It is also possible to change the recoding

To design 00073 in two parts, the length of the

00074 adjusting part assigned to the recoding part

00075 assumed the depth of the tumbler entry opening

00076 speaks. 00077

Another alternative is characterized in that

00079 at least one recoding magnet in its length

Corresponds to the thickness of the slide and when abutting against

00081 wide area of the adjustment part from its locked position

00082 is raised to the locking plate. In such a positive

00083 on the adjustment part the slide is by means of the key

00084 sels - for example a key card - relocatable _. ,

However, the adjustment part is shifted so that a

00086 tumbler entry opening the transcoding magnet

00087 lies opposite, this can be

00088 key in the entry opening

00089 chen and block the slide displacement. 00090

According to the invention, it is advantageous to the adjustment part

To design 00092 as a hub and by means of a

00093 bottom surface of the lock housing push-through tools

00094 total angle of rotation. The tool is on his

00095 insert end designed so that a positive coupling

00096 tion to the adjustable part can be produced. The different

00097 angular positions of the adjustment part can

00098 to be fixed by locking to self-adjustment of the

Exclude 00099 adjustment part. 00100

00101 Below are several embodiments of the

00102 invention explained with reference to the drawings. It shows 00104 shows a view of a 00105 lock designed according to the invention with an associated key designed as a key card 00106, 00107 00108 FIG. 2 partly in a side view, partly in a longitudinal section 00109 the lock before the key is inserted, 00110 00111 FIG. 1 shows a representation corresponding to FIG. 2 , 00112 but with the key inserted and the slider 00113 attached - coupling the external turning - 00114 handle with the handle pin, 00115 00116 Fig. A 00117 section parallel to the sliding plane through the adjusting element, 00118 00119 Fig. A section of the lock in the area of 00120 adjusting member, relating to a modified 00121 configuration and 00122 00123 Fig. Another variant in the area of the adjusting member 00124. 00125 00126 The lock 00127 1, which can be assigned to a hotel room door, for example, has a lock case 00128 2 which can be fixed on the outside of the door and has a rectangular outline, which has an outside turning handle 3 at one end 00129. With the aid of this, a latch (not illustrated) of a mortise lock built into the door can be withdrawn in 00130. On the other hand, the latch can always be retracted from the inside of the 00132 door by means of an inside turning handle which is not clearly shown. From the end of the lock case 2 opposite the outside turning handle 3, a plug-in slot 00136 for a key 5 extends. Regarding the same 00137, it is a regionally magnetized 00138 key card with a roughly rectangular outline. 00139 Inside the lock case 2 takes a lock

00140 housing 6, which consists of a bottom part 7, a

00141 middle part 8 and a cover part 9 is composed. For

00142 the middle part 8 is aluminum, while that

00143 bottom part 7 and the cover part 9 made of plastic

00144 hen. Is between the cover part 9 and the middle part 8

00145 a also made of plastic, plate-shaped

00146 designed slide 10, which with its

00147 abuts a wide area on the middle part 8. Against-

00148 overlying guide surface for the slide 10 forms

00149 a locking plate made of brass 11. This is

00150 immovably inserted in the cover part 9. In the blocking

00151 plate 11 holes 12 are aligned in the in Fig.

00152 2 illustrated locking position of the lock with

00153 through holes 13 of the slide 10. In this

00154 are magnetic tumbler pins 14. It is not

00155 necessary, a tumbler pin 14 in each bore 13

00156 because the number, the location and the polar

00157 did the tumbler pins 14 after the respective opening

00158 code combination of lock 1 sets up. 00159

00160 is on the other side of the locking plate 11

00161 is also made of brass baffle 15, the

00162 in turn rests on an anchor plate 16. Latter

00163 is of compression springs supported on the cover part 9

00164 17 held in position. The anchor plate 16 loading

00165 stands in contrast to the other components made of ferro-

00166 magnetic material. The anchor plate 16 therefore pulls

00167 the magnetic tumbler pins 14, consequently

00168 engage in the holes 12 of the locking plate 11. In the

00169 engagement position of the magnetic tumbler pins 14

00170 the slide 10 can not from its basic position

00171 to be moved. It is possible to drill part of the

00172 gen 13 of the slider 10 in rotary, not illustrated

00173 body of the slider to provide a change in 00174 Make locking codes by turning this rotating body

00175 to be able. 00176

00177 Both the anchor plate 16 and the guide plate 15

00178 leave the insertion slot 4 between them.

00179 ren transverse edges of the guide plate 15 and the anchor plate 16th

00180 are angled in opposite directions and

00181 form a gusset for the key to be inserted

00182 card or key 5. 00183

00184 A serving as a return spring 18 is with your

00185 one end on a cross pin 19 of the middle part 8

00186 set. The other end of the tension spring 18 engages

00187 a pre-penetrating a slot of the central part 8

00188 jump 20 of the slide 10, whereby this in his

00189 in Fig. 2 basic position is moved.

00190 The projection 20 are two chamfered lugs 21, 22 of the

00191 slide 10 upstream, which also like the pre

00192 jump 20 reach through the middle part 8. The bevels

00193 gen 21 ', 22 * of the lugs 21, 22 are approximately the same

00194 designed. They grip obliquely angled rags

00195 23, 24 of a displaceable transversely to the slide movement,

00196 rigid arm 25 which in the area of the key card

00197 insertion end has a spring zone 25 '. Last

00198 tere is in the corresponding area of the lock housing 6

00199 clamped. The opposite end of the attachment

00200 end of arm 25 continues into a bend 26,

00201 to which a fork-shaped end 27 adjoins

00202 closes. This engages in an annular groove 28 of an inside

00203 toothed coupling sleeve 29. In the locking position

00204 lung according to FIG. 2, there is no rotary connection between

00205 of the coupling sleeve 29 and a coaxially arranged to it

00206 th pinion 30 before. Since this carrier is the external

00207 handle 3, only the latter can be rotated

00208 without taking the coupling sleeve 29 too 00209 effect. The one with the coupling sleeve 29 in composite

00210 handle mandrel 31 is therefore not included

00211 men. 00212

00213 In the insert-side area, the middle part 8 forms one

00214 in the direction of the base part 7 pointing dome 32 for receiving

00215 me of a tumbler 33. The latter is as a

00216 designed and designed in the form of a turntable

00217 forms. The locking part 33 or turntable has

00218 is rich in its wide area on the slide 10

00219 a radially outwardly projecting collar 34, which

00220 fits in shape in the cavity 35 of the dome 32. In

00221 the center of the dome 32 has an insertion opening 36

00222 on that with a push-through opening 37 of the bottom surface

00223 7 'of the bottom part 7 is aligned. With these openings 36,

00224 37 corresponds to a cross-sectional coupling

00225 opening 38 of the tumbler 33 for a in Fig. 2nd

00226 dash-dotted illustrated bar-shaped tool

00227 39. By means of the same, the turntable-like

00228 tumbler 33 in 90 ° steps

00229 len. The locking means, which are not illustrated, can be used

00230 rotational angle positions of the turntable 33 are fixed. 00231

00232 According to the first embodiment, shown in the

00233 Fig. 1 - 4, has the turntable 33 on the

00234 slide 10 facing wide area a tumbler input

00235 step opening 40. With this is aligned in a transverse

00236 hole 41 of the slide 10 guided recoding magnet

00237 42. This too is like the other tumbler pins 14

00238 designed as a rod-shaped permanent magnet - the length

00239 of the recoding magnet corresponds to the thickness of the

00240 bers 10. The transcoding magnet 42 does not engage

00241 an opening of the locking plate 11, but is supported

00242 on their facing broad area. 00243 00244 In addition to the transcoding magnet 42 more

00245 transcoding magnets 43, 44, 45 arranged on sliding

00246 chem pitch circle diameter around the axis of rotation of the

00247 partly 33 are grouped. The rotation angle distance between

00248 the individual recoding magnet is 90 °. The

00249 also in corresponding transverse holes 41 of the slide

00250 10 housed recoding magnets 43, 44, 45

00251 zen also corresponds to the thickness of the slide 10

00252 length. 00253

00254 The following mode of action occurs:

00255 To lock 1 from the outside of the door by means of

00256 To be able to operate the external turning handle 3, it is

00257 loaned the correspondingly encoded key card 5 in the

00258 to insert the key card slot 4. in this connection

00259 is the anchor plate acted upon by the compression springs 17

00260 te 16 shifted in the transverse direction. In the completely

00261 pushed position occurs the key card 5 with your

00262 insert-side end edge 5 'in front in the direction of

00263 cover part 9 facing slide stop 10 '. In this

00264 position are the magnetic tumbler pins 14 so

00265 shifted that they the holes 12 of the locking plate 11th

Leave 00266. In this insertion position, the recoding

00267 magnet 42 a magnetized area of the key

00268 seikarte 5 opposite, which loads it in the pulling direction

00269 continuous The recoding magnet 42 therefore does not enter the

00270 tumbler entry opening 40 of the tumbler

00271 of the 33 or turntable. Now the further

00272 tion of the key card 5, the

00273 slide 10 against the force of the tension spring 18

00274 is being towed. Along with the advance of the

00275 slide 10 is actuated by the nose 21 of the arm 25

00276 strikes, which pivots about its spring zone 25 ', 0Q277-comp. Fig. 3. Since the free, forked end 27 of the 00278 arm 25 is in engagement with the coupling sleeve 29, 00279 this is shifted in such a way that it then

00280 zel 30 overlaps. In this way, a rotating connection

00281 fertilizer brought to the mandrel 31 so that an actuation

00282 adjustment of the external turning handle 3 for a shift

00283 a trap coupled with the presser pin 31. 00284

00285 is not shown that the slide 10 in its

00286 locked position. Only during the

00287 pulling the key card 5 is this rest

00288 canceled. Then the slide 10 is the tension spring 18th

00289 moved back to its starting position. During this pre

00290 ganges, the coupling sleeve 29 is thereby left behind.

00291 gert that the other nose 22 of the slider 10 the rag

00292 24 of the arm 25 and thus the arm 25 in

00293 returns its end position. 00294

00295 Tool 39 is used to change the locking code.

00296 By means of this through the bottom surface 7 'of the lock housing

00297 ses 6 push-through tool 39, the rotary

00298 disc 33, for example at 90 counterclockwise

00299 turn. Then the recoding magnet 43 is in

00300 aligned alignment to the tumbler entry opening

00301 nung 40, with which the task of an active transcoding

00302 magnets fulfilled. The mode of action is fundamental

00303 so that the respectively valid key is at the right one

00304 position is coded attractively, the three other positions

00305 NEN, however, are always coded repulsive. This will

00306 when operated with the wrong key

00307 valid recoding magnet in the entry opening 40

00308 controlled locking. 00309

00310 According to the embodiment according to FIG. 5, the recoding

00311 magnet 46 in a hole 47 of the locking plate 11. In

00312 its length corresponds to the recoding magnet 46 of the

00313 thickness of the slide 10. According to the position according to FIG. 5 00314 the recoding magnet 46 has no guard locking inputs

00315 step opening 40 opposite. When using a pre-

00316 written key card is therefore also the Umσo-

00317 dierungsmagnet 46 from the hole 47 of the locking plate 11th

00318 excavated so that the slide 10 is displaceable. Becomes

00319 brought about a step rotation of the turntable 33, so

00320 that the tumbler entry opening 40 in the

00321 dash-dotted position, so the key

00322 5 a shift of the recoding magnet 46, which

00323 then blocks into the tumbler entry opening 40

00324 dips. This means that all subsequent keys are

00325 regardless of how the key in the

00326 the area opposite the recoding magnet 46

00327 is magnetized. For example, the guest from

00328 interior the possibility of all keys

Lock out 00329. 00330

00331 According to FIG. 6 there are two recoding magnets 48, 49 in

00332 Direction of displacement of the slide 10 in a row.

00333 Both are aligned with tumbler entry openings 50, 51

00334 of the turntable 33 '. The entry opening 51 is through

00335 smaller than the opposite recoding

00336 magnet 49. In contrast, the recoding magnet 48 can

00337 its step-like shoulder 48 'into the

00338 attitude entrance opening 50 to intervene. The the

00339 Closing key card must be obtained in this way

00340 be that there is no displacement of the transcoding magnet

00341 48 causes. Then you can use the key card

00342 slider 10 be moved forward without hindrance. 00343

00344 If the locking code is to be changed, use the

00345 tool 39 to move the turntable 33 'so that

00346 the entry opening 51 to the recoding magnet 48 and

00347 the inlet opening 50 to the recoding magnet 49

00348 is opposite. If a key is now used, the 00349 has incorrectly polarized areas, so

00350 the recoding pin 48 'into the entry opening 51

Immerse 00351. This also applies to the recoding

00352 added 49, which then enters the inlet opening 50

00353 picks up. 00354
