Definitions

  • the invention relates to a locking system consisting of a lock and several keys, in which the lock of the lock determined by magnetically controllable tumblers can be changed in such a way that the lock code of the lock, which initially corresponds to the coding of the first key, can be changed by relocating at least one tumbler within the lock the coding of a successor key, the coding being formed by individual permanent magnets which are arranged in openings in a slide and can be lifted out to a locking plate by means of correspondingly positioned magnetization regions of a key which can be brought in parallel to the slide, after which the slide can be moved into a lock-open position, whereby some of the permanent magnets are provided as recoding magnets.
  • the slide takes up rotatably associated carriers which mesh with one another and which are each equipped with a recoding magnet.
  • the carrier with the recoding magnet can be displaced by changing the locking code by means of the successor key. This saves the first key.
  • the invention has for its object to design a generic lock in a simple manner so that the variation options for changing the lock code are increased.
  • This object is achieved in a lock of the type in question in that the tumbler is designed as an adjusting part associated with the recoding magnet such that the tumbler entry opening for the recoding magnet can be moved from the aligned position to the recoding magnet.
  • the transcoding magnet does not need to be moved from its position to another position. Rather, this is done by changing the position of the tumbler element assigned to the recoding magnet and designed as an adjusting part. Along with a displacement of the adjustment part, the guard locking entry opening for the transcoding magnet also reaches the latter from the aligned position. If, when the tumbler entry opening is aligned with the transcoding magnet, such a key is inserted, which causes the transcoding magnet to be pushed off in the direction of the tumbler entry opening, the slide cannot be advanced. Its displacement therefore requires a key which is magnetized in the corresponding area in such a way that it attracts the transcoding magnet so that it does not dip into the tumbler entry opening. The most diverse versions can be realized on this basis.
  • a variant is characterized in that an adjusting part has several tumbler entry openings which differ in diameter and / or depth. If, for example, tumbler entry openings of different sizes are selected, the recoding magnet can only be displaced by the correspondingly magnetized key. if the tumbler inlet opening is the same size or larger in diameter than the relevant recoding magnet. It is also possible to design the transcoding magnets in two parts, the length of the section of the transcoding magnet assigned to the adjustment part corresponding to the depth of the tumbler entry opening.
  • At least one recoding magnet corresponds in length to the thickness of the slide and is raised from its locked position to the locking plate when it strikes the wide surface of the adjusting part.
  • the slide can be displaced by means of the key, for example a key card.
  • the adjustment part is shifted such that a tumbler entry opening is opposite the recoding magnet, it can dip into the entry opening with appropriate magnetization of the key and block the slide displacement.
  • the adjustment part as a turntable and to adjust the angle of rotation by means of a tool which can be pushed through the bottom surface of the lock housing.
  • the tool is designed at its insertion end so that a positive coupling to the adjustment part can be produced.
  • the various rotational angle positions of the adjustment part can be fixed by detents to prevent the adjustment part from self-adjusting.
  • the lock 1 which can be assigned, for example, to a hotel room door, has a lock case 2 which can be fixed on the outside of the door and has a rectangular plan, which has an external turning handle 3 at one end.
  • a latch (not illustrated) of a mortise lock installed in the door can be withdrawn.
  • the latch can always be withdrawn from the inside of the door by means of an internal turning handle (not shown).
  • An insertion slot 4 for a key 5 extends from the end of the lock case 2 opposite the external turning handle 3.
  • it is a key card that is magnetized in some areas and has a roughly rectangular outline.
  • the lock case 2 accommodates a lock housing 6, which is composed of a base part 7, a middle part 8 and a cover part 9.
  • Aluminum is used for the middle part 8, while the bottom part 7 and the cover part 9 consist of plastic.
  • plate-shaped slider 10 is guided, which rests with its one broad surface on the middle part 8.
  • the opposite guide surface for the slide 10 forms a locking plate 11 made of brass. This is immovably inserted in the cover part 9. Holes 12 in the locking plate 11 are aligned in the locking position of the lock illustrated in FIG. 2 with through bores 13 of the slide 10.
  • Magnetic tumbler pins 14 lie in these. It is not necessary to provide a tumbler pin 14 in each bore 13, since the number, the position and the polarity of the tumbler pins 14 depend on the respective opening code combination of the lock 1.
  • the locking plate 11 On the other side of the locking plate 11 there is a baffle 15, also made of brass, which in turn rests on an anchor plate 16. The latter is held in position by compression springs 17 which are supported on the cover part 9.
  • the anchor plate 16 consists of ferromagnetic material.
  • the armature plate 16 thus attracts the magnetic tumbler pins 14, which consequently engage in the holes 12 in the locking plate 11.
  • the slide 10 In the engaged position of the magnetic tumbler pins 14, the slide 10 cannot be moved out of its basic position. It is possible to provide a part of the bores 13 of the slide 10 in rotating bodies of the slide, not illustrated, in order to change the To be able to make locking codes by turning these rotating bodies.
  • Both the anchor plate 16 and the guide plate 15 leave the insertion shaft 4 between them.
  • the front transverse edges of the guide plate 15 and the anchor plate 16 are angled in opposite directions and form a gusset for the key card or key 5 to be inserted.
  • a tension spring 18 serving as a return spring is fixed at one end to a cross pin 19 of the central part 8.
  • the other end of the tension spring 18 engages on a projection 20 of the slide 10 passing through a slot of the central part 8, as a result of which the latter is moved into its basic position illustrated in FIG. 2.
  • the projection 20 is preceded by two bevelled lugs 21, 22 of the slider 10 which, like the projection 20, extend through the middle part 8.
  • the bevels 21 ', 22' of the lugs 21, 22 are designed approximately in the same direction. They engage on obliquely angled tabs 23, 24 of a rigid arm 25 which can be displaced transversely to the slide movement and which has a spring zone 25 'in the region of the end of the key card insertion side.
  • the middle part 8 forms a dome 32 pointing in the direction of the bottom part 7 for receiving a tumbler element 33.
  • the latter is designed as an adjusting part and is designed in the form of a turntable.
  • the locking part 33 or turntable has a radially outwardly projecting collar 34 in the area of its wide surface abutting the slide 10, which collar fits into the cavity 35 of the dome 32 in a form-fitting manner.
  • the dome 32 has an insertion opening 36 which is aligned with a through opening 37 of the bottom surface 7 'of the bottom part 7.
  • Corresponding to these openings 36, 37 is a cross-sectional coupling opening 38 of the tumbler 33 for a rod-shaped tool 39 shown in phantom in FIG. 2.
  • the turntable-like tumbler 33 can be adjusted in 90 ° increments.
  • the rotational angle positions of the turntable 33 can be fixed by means of locking means (not shown).
  • the turntable 33 has a tumbler entry opening 40 on its wide surface facing the slide 10.
  • a recoding magnet 42 guided in a transverse hole 41 of the slide 10 is aligned with this. This is also like the remaining tumbler pins 14 are designed as rod-shaped permanent magnets.
  • the length of the transcoding magnet corresponds to the thickness of the slide 10.
  • the transcoding magnet 42 does not engage in an opening of the locking plate 11, but is supported on its facing broad surface.
  • transcoding magnet 42 In addition to the transcoding magnet 42, further transcoding magnets 43, 44, 45 are arranged, which are grouped on the same pitch circle diameter around the axis of rotation of the adjusting part 33. The angle of rotation distance between the individual recoding magnets is 90 °.
  • the transcoding magnets 43, 44, 45 which are likewise accommodated in corresponding transverse holes 41 of the slide 10, likewise have a length corresponding to the thickness of the slide 10.
  • the recoding magnet 42 therefore does not enter the tumbler entry opening 40 of the tumbler 33 or turntable.
  • the key card 5 can now be moved further, the slider 10 being dragged against the force of the tension spring 18.
  • the arm 25 is acted upon by its nose 21, which pivots about its spring zone 25 ', see FIG. 3. Since the free, forked end 27 of the arm 25 is in engagement with the coupling sleeve 29, it is moved such that it then engages over the pinion 30. In this way, a rotary connection to the pusher mandrel 31 is brought about, so that actuation of the external turning handle 3 leads to a displacement of a latch coupled to the pusher mandrel 31.
  • the slide 10 latches in its forward position. This rest is only released when the key card 5 is removed. Then the slide 10 is moved back into its starting position by the tension spring 18. During this process, the coupling sleeve 29 is moved back in that the other nose 22 of the slide 10 acts on the tab 24 of the arm 25 and thus returns the arm 25 to its end position.
  • the tool 39 is used to change the locking code.
  • this tool 39 which can be pushed through the bottom surface 7 'of the lock housing 6, the turntable 33 can be rotated counterclockwise, for example, by 90 °.
  • the transcoding magnet 43 lies in alignment with the tumbler entry opening 40, thus performing the task of an active transcoding magnet.
  • the principle of operation is such that the respectively valid key is attractively coded in the correct position, while the other three positions are always coded repulsively. As a result, when a wrong key is actuated, the transcoding magnet which is valid at the time is inserted into the entry opening 40 in a blocking manner.
  • the recoding magnet 46 engages in a hole 47 in the locking plate 11.
  • the length of the recoding magnet 46 corresponds to the thickness of the slide 10. According to the position according to FIG. 5 there is no tumbler entry opening 40 opposite the recoding magnet 46. If a correct key card is used, the recoding magnet 46 is therefore also lifted out of the hole 47 in the locking plate 11, so that the slide 10 can be displaced. If the turntable 33 is rotated in steps so that the tumbler entry opening 40 reaches the dot-dash position, the key 5 causes the transcoding magnet 46 to be displaced, which then plunges into the tumbler entry opening 40 in a blocking manner. In this way, all of the subsequent keys are canceled, regardless of how the key is magnetized in the area opposite the recoding magnet 46. For example, from the inside of the room, the guest has the option of locking out all keys.
  • two transcoding magnets 48, 49 lie one behind the other in the direction of displacement of the slide 10. Both are aligned with tumbler entry openings 50, 51 of the turntable 33 '.
  • the entry opening 51 is smaller in diameter than the transcoding magnet 49 opposite it.
  • the transcoding magnet 48 with its step-like shoulder 48 ' can intervene in the tumbler entry opening 50.
  • the key card effecting the closing must be such that it does not cause the transcoding magnet 48 to be displaced. Then the slide 10 can be advanced without hindrance by means of the key card.
  • the turntable 33 ' is to be displaced by means of the tool 39 such that the inlet opening 51 is opposite the transcoding magnet 48 and the inlet opening 50 is opposite the transcoding magnet 49. If a key is now used, the not correctly polarized areas, the recoding pin 48 'can dip into the inlet opening 51. This also applies to the recoding magnet 49, which then engages in the entry opening 50.
