Definitions

  • the invention relates to a combination of security key and lock cylinder according to the preamble of claim 1.
  • Security key and lock cylinder of the type mentioned have become known in numerous designs. With security keys for high-quality systems, it is essential that these can not be easily copied on relatively simple drilling and milling machines.
  • a security key with a high copy security can be achieved according to EP 0 621 384 B1 of the Applicant, by providing the shaft of the security key with a control element which is designed as a pin and displaceably mounted in the shaft. With an additional locking in the lock cylinder this control can be classified. Such a key can not be copied at a reasonable cost.
  • a so-called spiked key with a similar control has become known from EP 0 802 289. Even with this key, a comparatively high copy security is ensured.
  • a disadvantage of the said security key are the costs incurred by the installation of the mentioned controls and the additional tumblers in the lock cylinder. These controls can also adversely affect the combinatorics.
  • DE 197 45 834 A discloses a reversible key for lock cylinder having two broad side surfaces, each with a set of holes. All tumblers of the lock cylinders are each below the rotor in a cylinder bag. The classification of the tumblers is done with the holes of the downward broadside of the key inserted in the keyway. The two mentioned drilling sets are offset from one another in the longitudinal direction of the key shank. Accordingly, depending on the turning position, the insertion depth of the key is different. The insertion depth is determined by shoulders, which are offset according to the different insertion depth in the longitudinal direction of the key to each other. Since the tumblers do not run radially to the rotor, the pins of the tumbler must be stored against rotation. The corresponding holes must be pushed. In the rest position of the rotor, the key channel is aligned horizontally and accordingly the key must be inserted. A similar key has become known from DE 76 04 852 U.
  • GB-A-2 356 016 a security key and a lock cylinder have become known, wherein an additional control surface of the security key is formed by a laterally bent and projecting nose. In the front of the rotor also a recess is incorporated.
  • a security key and a lock cylinder have become known.
  • the lock cylinder usual pin tumblers and a restoring fuse element are arranged.
  • the restoring securing element is connected to a lever which can be actuated by a key bit of the security key, so that when the key is fully inserted into the keyway, the securing element is displaced into the cylinder core.
  • the security key has a laterally projecting bridging element, which connects the key grip with the key bit and which engages with a fully inserted key in a recess of the rotor.
  • the bridging element has a bore.
  • the invention has for its object to provide a security key and lock cylinder, which offers a high copy protection and can still be produced comparatively inexpensive.
  • the object is achieved in a generic combination of security key and lock cylinder according to claim 1.
  • the front elongated end of the rotor and the rear end of the key shank used to provide additional control surfaces.
  • These control surfaces can be produced particularly inexpensively by depressions and in particular by slots in the extended front end of the rotor.
  • the control surfaces are produced particularly inexpensively by recesses and in particular milling on shoulders of the key shank.
  • the security key may be a reversible key with holes in the key shank or another security key, such as a key or cam key.
  • An essential advantage of the inventive combination of security key and locking cylinder is seen in the fact that it is backward compatible.
  • the security key and the lock cylinder according to the invention can readily be converted into an existing one System to be integrated.
  • a master key is possible, which serves both the already existing lock cylinder and the inventive lock cylinder.
  • the existing security keys can not open the corresponding new lock cylinder.
  • every existing locking system can be expanded and upgraded.
  • the additional control surface at the rear end of the shaft requires a relatively high effort for copying, since additional and usually non-existent tools and special blanks are required.
  • Another advantage of the invention is also seen in that the calculation of a plant is simplified.
  • the combinatorics is substantially increased by the invention and simplifies the subdivision of groups.
  • FIG. 1a shows a security key 1 having a shaft 6 and a handle 14.
  • the key 1 is a so-called flat key or reversible key.
  • the key can also be a spanner or cam key.
  • the shaft 6 has in a conventional manner control bores 7, which are usually incorporated in the broad sides and in the narrow sides of the shaft 6. These control bores 7 serve to classify tumblers, not shown here and known per se, of an associated closing cylinder 2, which, according to FIG. 3 a, has a stator 3 and a rotor 4.
  • the shaft 6 of the key 1 has a front end 6a and a rear end 6b. With the front end 6 a of the key 1 is inserted as usual in a keyway 5 of the rotor 4. By introducing the shaft 6 in the keyway 5, the tumblers mentioned are classified. As a result, the rotor 4 is unlocked and can be rotated on the handle 14 of the key for actuating the lock.
  • the key 1 has at its rear end 6 b additional control surfaces 9, which are formed by laterally projecting shoulders 15 and recesses 13 in these shoulders 15. These control surfaces 9 cooperate with a corresponding control surface 8 of the rotor 4 shown in FIG.
  • the control surface 8 is formed by a recess 10 which is incorporated in an extended front end 4a of the rotor 4 is.
  • the control bores 7 are positioned so that the corresponding tumblers are at closing height when the control surfaces 9 abuts against the control surface 8.
  • the recess 10 can be made for example with a milling tool.
  • the recess 10 is laterally offset as shown in Figure 2a. Accordingly, the control surfaces 9 are also offset laterally in the key 1a.
  • control surfaces 9 are rotationally symmetrical to each other with a reversible key. If the shaft 6 is inserted into the keyway 5, the one or the other shoulder engages in the slot 10, respectively, until a control surface 9 bears against the control surface 8.
  • the control surface 8 forms here a stop for the security key.
  • control surfaces 9' are present, which are each formed by two lateral recesses 13 '.
  • the control surfaces 9 ' are arranged centrally with respect to the plane of the key 1'.
  • the associated rotor 4 ' is shown in FIG. 2b.
  • the recess 10 ' is as shown centrally disposed to the keyway 5 and forms a control surface 8'.
  • the recess 10 ' is here a laterally and frontally open slot.
  • control surfaces 9" are formed by recesses 13 ".
  • the corresponding rotor 4" is shown in Figure 2c.
  • the recess 10 '' is also laterally offset, but in the other direction than in Figure 2a 'The control surface 8''is formed by the slot 10''The slots 10, 10' and 10 '' and the corresponding recesses 13, 13 'and 13 "can also be designed differently.There are also intermediate stages possible.In addition, the slots 10, 10 'and 10" need not necessarily be continuous and linear.
  • Figures 5a to 5h illustrate the large number of closures, which by different recesses 30, 30 ', 30 ", 30"' and 31, 31 ', 31 "and 31"' in the front end of the rotor 4 and 4 'be respect can be.
  • the associated security keys 1 and 1 ' have corresponding control surfaces 9 which cooperate with the control surfaces of these recesses.
  • the invention enables the construction of locking systems with group and Einzelschliessungen.
  • Existing plants can be supplemented with appropriate rotors and keys.
  • the production with rotors extended at the head and keys with the mentioned control surfaces or cams 12 can be produced comparatively inexpensively.
  • the slots or recesses in the elongated head of the rotor can be varied in many ways. Also numerous variations of the control surfaces 9 and shoulders 15 are possible.
  • FIG. 4 shows a lock cylinder half 32, which has a stator 3 and a rotor 4. As can be seen, the front end 4a of the rotor 4 projects beyond the stator 3.
  • the key 1 here is a toothed key with which tumblers 33 can be arranged to release the rotor 4.
