Definitions

  • Locking device with a cylinder lock and a flat key
  • the invention relates to a locking device with a cylinder lock and a flat key
  • the cylinder lock having a rotor rotatable in a stator with a key channel, and guides with tumblers arranged approximately at right angles to the longitudinal axis of the rotor and parallel to the broad sides of the key channel are provided with drivers which protrude into the key channel
  • the flat key has at least one guide groove on each broad side, into which the drivers of the tumblers engage when the key is inserted into the key channel.
  • Such a locking device with a cylinder lock and a flat key is known from US-B-3 264 852 or EP-B-0 008 310.
  • guide grooves are arranged on both broad sides of a reversible flat key on the part which is inserted into the lock. These guide grooves run in a curve and form guides and positioning areas for drivers which are part of the locking devices in the lock.
  • the locking tumblers are mounted in guides of the rotor in the lock, these guides running approximately at right angles to the lock axis and parallel to the broad sides of the key channel.
  • the locking tumblers are freely movable in the guides and are not spring-loaded.
  • the ends of the locking tumblers engage in bores in the stator and thus penetrate the separating or shearing surface between the rotor and the stator at the castle.
  • the drivers of the locking tumblers projecting into the key channel have the same dimensions as the guide grooves on the key. They are therefore positively guided in both directions, which means that the locking tumblers can be positioned precisely in the unlocking position with the aid of the guide grooves.
  • the locking device when the flat key is completely inserted into the key channel, at least one of the tumblers is not held in the unlocking position by the guide position.
  • This additional positioning element has the advantage that the drivers connected to the locking tumblers no longer have to be positively guided by the guide groove on the key.
  • the grooves on the key therefore have enlarged areas in which there are spaces between the side walls of the grooves and the driver.
  • the locking device When the key is fully inserted, there is at least one driver in this extended area of a groove, and the locking device must therefore be positioned in this area using the additional positioning element the. If this positioning element is missing, the tumbler cannot be brought into the unlocked position, ie the lock cannot be opened.
  • the additional positioning element consists of a permanent magnet arranged in the key bit and a magnetic one arranged in the tumbler
  • the corresponding magnetic body must also be simulated on the key.
  • this replica is not possible on the usual copying machines.
  • Another advantage is that the additional positioning element can be formed by an additional coding on the rear side of the tumbler and an associated two-part locking element. This arrangement permits additional concealment of the opening positions of the locking tumblers and makes it more difficult to recognize the functional functions between the key and according to the invention
  • Cylinder lock The arrangement of at least one additional positioning element with a magnetic connection and at least one additional positioning element with a coding on the rear of the tumbler results in a combination in which the cylinder lock with a copied key also when additional magnetic forces or other measures to crack the lock cannot be unlocked. This also improves the security of the locking device according to the invention.
  • FIG. 2 shows a cross section through a locking device according to the invention, with the additional positioning elements
  • FIG 3 shows a side view of a key with grooves designed according to the invention and inserted permanent magnets.
  • the locking device shown in FIG. 1 consists of a cylinder lock 1 and a flat key 2, in the example shown a flat reversible key. It corresponds essentially to the state of the art according to US Pat. No. 3,264,852.
  • the cylinder lock 1 is shown in simplified form and comprises a rotor 3 which can be rotated in a stator 4 and a sleeve 5 which covers the entire cylinder lock 1 as a jacket surrounds.
  • a key channel 6 with a rectangular cross section is incorporated in the rotor 3.
  • the key bit 21 of the key 2 can be inserted into this key channel 6.
  • guideways 15, 16 are milled in the form of grooves, which are used to position the locking elements in the cylinder lock 1.
  • the groove 15 is at the bottom and the groove 16 is on the wide side 14, which is not visible. With respect to the central axis 56 of the key 2, there are therefore grooves 15, or 16 of the same shape, diagonally opposite one another on the two broad sides 13, 14.
  • five tumblers 10 are arranged in the rotor 3 on each broad side 8, 9 of the key channel 6, so that ten locking elements result.
  • These tumblers 10 are mounted in guides 11 of the rotor 3 and can be displaced transversely to the longitudinal axis 7 of the lock 1.
  • coupling elements not shown available, which cooperate with locking elements, also not shown, such as a door lock.
  • FIG. 2 shows a cross section through a cylinder lock 1, specifically in the region of two guides 11 arranged on both sides of the key channel 6.
  • these two guides 11 not normal tumblers 10 according to FIG. 1 are arranged, but tumblers 17 and 18 modified according to the invention
  • the guides 11 interact with bores 42, 43 in the stator 4, so that the tumblers 17, 18 shown and any other tumblers 10 can be moved in the direction of the axes 57, 58.
  • the key 2 In this position of the rotor, the key 2 can thus be withdrawn from the key channel 6 or inserted into it.
  • the drivers 12, 12 ', 12''connected to the tumblers 17, 18 and 10 follow the course of the guide grooves 15 and 16 on the broad sides 13 and 14 of the key 2, the ends of the tumblers 17 , 18 and 10 can extend into the areas of the bores 42, 43. With the key removed, the ends of the tumblers 17, 18 and 10 engage in the bores 42 and 43 in the stator 4 and lock the rotor 3 against rotation. In the position of the tumblers 17 and 18 shown in FIG. 2, the rotor 3 can be rotated in the stator 4, ie the tumblers 17, 18 are in their unlocking position since there is no end over the shear line 40 between the rotor 3 and the stator 4 protrudes.
  • the other tumblers 10 arranged in the lock 1 are also in their unlocked position, with the tumblers 12 not shown in FIG. 2, the drivers 12 being guided on both sides by the guide grooves 15, 16 on the key 2 and through which Guide groove areas are positioned.
  • the drivers 12 of the tumblers 10 are in contact with the side walls 22, 23 of the grooves 15, or the side walls 24, 25 of the grooves 16.
  • the grooves 15, 16 on the broad sides 13, 14 of the key bit 21 have different functional areas.
  • the width of the grooves 15, 16 is widened and forms a so-called free area 51. In this expanded free area 51 of the grooves 15, 16, the width of the grooves 15, 16 is greater than that Dimension of the driver 12 'or 12''.
  • An intermediate space 47 or 48 is formed between the drivers 12 'or 12''which engage in the grooves 15, 16 and at least one of the side walls 22, 23 of the groove 15 or 24, 25 of the groove 16.
  • a magnetic element 46 is arranged in the tumbler 18, which cooperates with a permanent magnet 44 installed in the key bit 21.
  • the permanent magnet 44 on the key bit 21 pulls the magnetic element 46 in the tumbler 18 upward, as a result of which the driver 12 'is pulled against the side wall 23 of the groove 15. In this position the tumbler 18 is fixed precisely in the unlocking position. If there was no permanent magnet 44 on the key bit 21, the tumbler 18 would fall down until the driver 12 ′′ would rest against the side wall 22 of the groove 15.
  • the permanent magnet 44 and the magnetic element 46 can also cooperate in such a way that the permanent magnet 44 holds the tumbler 18 in a predetermined position via the magnetic element 46 without the driver 12 ′′ one of the side walls 22, 23 of the guide groove 15 touched.
  • a pre-positioning area is arranged in the guide groove 15, which is used when the key is inserted
  • the tumbler 18 locks the rotor 3 over the stator 4 if the permanent magnet 44 is not present on the key bit 21 or is not correctly positioned.
  • an additional locking element 29 is arranged between the tumbler 17 and the stator 4.
  • This blocking element 29 is in two parts and consists of a first part 30, which is supported in a bore 34 in the stator 4, and a second part 31, which is supported in a bore 35 in the rotor 3.
  • the axes 32 of the two bores 34 and 35 coincide.
  • the two bores 34 and 35 form a common guide bore in which the blocking element parts 30 and 31 between the stator 4 and the rotor
  • the first locking element part 30 is cup-shaped and is pushed by a compression spring 60 in the direction of the tumbler 17.
  • the second locking element part 31 has a shoulder which interacts with the shoulder of the stepped bore 35.

  • the rear side 19 of the tumbler 17 is the side of the tumbler 17 which faces away from the key channel 6. This rear side 19 is equipped with a positioning surface 37, in which coding 28 in the form of depressions 39 and crests 38 are arranged.
  • the end 36 is shaped in accordance with the flank shapes of the depressions 39 and ends in a tip in the example shown. If the tumbler 17 is displaced in the direction of its longitudinal axes 57 or parallel to the broad sides 8, 9 of the key channel 6, the end 36 of the second locking element part 31 engages in the recesses 39 or between the crests 38. The recess next to the outermost crest 38 in the positioning surface 37 of the tumbler 17 holds the tumbler 17 after the key 2 has been removed from the lock 1 in the locked position, in which one end of the tumbler 17 in the bore 42 of the stator 4 engages.

  • the tumbler 17 is brought into the unlocking position shown by a prepositioning area arranged directly in front of the free area 51 of the groove 16 and in This position is held by the additional locking element 29.
  • a permanent magnet is therefore not necessary for fixing the tumbler 17 in the unlocking position, but rather this fixing is carried out by the additional positioning element 26 on the rear side 19 of the tumbler 17 order of an additional positioning element 26 is preferably arranged in addition to a positioning element 27 with magnetic positioning, as shown on the right side of FIG. 2.
  • This makes it extremely difficult to recognize from the key how the lock is coded and which of the tumblers are held in the unlocking positions by additional magnetic positioning.

However, the exact copying of the grooves 15, 16 does not result in a key 2, which enables the opening of a lock 2 according to the invention equipped with additional positioning elements 26, 27. This makes the unauthorized copying of keys of this type considerably more difficult, since the magnets must also be arranged in the right place and in the right way. However, this is not possible with the machine tools available today and requires considerable additional effort.
  • lock / key sel systems of the type according to the invention can be equipped with improved tumblers 17 which have additional codings 28 on the rear 19. This brings additional encryption options to the lock and the key, which makes copying even more difficult.
