Definitions

  • the invention relates to a key for a lock cylinder with one in a chest area of a shaft arranged for actuating pin tumblers of Locking cylinder provided series of recesses, with a stop for supporting the key on the Lock cylinder for aligning the recesses opposite the pin tumblers.
  • the invention also relates a locking system with several locking cylinders and with Keys for unlocking the lock cylinder, with in a hierarchy level several keys for unlocking a common lock cylinder are designed and in another locker level a lock cylinder of one small number of keys can be unlocked with one arranged in each of the keys, with pin tumblers of the lock cylinder corresponding row of recesses, each with one on the key and the lock cylinder arranged stop for alignment a number of recesses with pin tumblers.
  • Such locking systems are in office units or residential units, in which several persons each have a key own and entitled in a first hierarchical level are, for example, the lock cylinder of a common door close, known. In another hierarchy level should the lock cylinder, for example of individual apartments or offices, only one each single key can be unlocked.
  • the pin tumblers of Lock cylinder to provide with electronicsuxen.
  • the post pin may have the post pin the recesses for unlocking the lock cylinder authorized key differently deep recesses exhibit. This often leads to community doors Lock cylinders equipped with pens while the lock cylinder of the apartment doors or offices no Have build pins.
  • a profile of the shaft designed to generate different hierarchy levels be.
  • Such a locking system is known from DE 43 05 176 A1 known.
  • the closing channels of the lock cylinder point a the profile of the authorized for unlocking key corresponding profile, so that only insert the authorized keys into the lock channel to let.
  • the key to be closed by all keys Lock cylinder accordingly has a wide Locking channel in which all keys can be inserted.
  • the key with which all lock cylinders closed accordingly has a narrow one Profile for insertion in all lock cylinders.
  • a disadvantage of the known shooting ranges is that the known key only the generation of a limited Allow number of hierarchy levels. Continue to increase a second separation point in the pin tumblers or the possibility of manipulating the profile of the key the risk of unauthorized unlocking of the The lock cylinder. In addition, construction pens usually have only very small dimensions and therefore can snag.
  • the invention is based on the problem of a key of the type mentioned above so that he the Use in the largest possible number of hierarchy levels allows. Furthermore, one should be as simple as possible established locking system created for several hierarchical levels become.
  • the first problem is solved according to the invention by that an additional row of recesses in the chest area the shaft is arranged and opposite the row of Recesses offset by a predetermined amount.
  • the additional row has more recesses in the chest area arranged as the lock cylinder pin tumblers exhibit.
  • Each of the rows of recesses is to contrast with a series of pin tumblers intended. This is due to the arrangement of the At the stroke, the series of recesses selected, which to be contrasted with the pin tumblers and thus the number of hierarchy levels with little effort elevated. Since the additional series in addition to the already existing Row of recesses can be arranged the key according to the invention particularly cost finished.
  • the recesses of the additional row can, for example placed exactly between the recesses of the row be.
  • the length of the shaft can be according to a advantageous embodiment of the invention particularly keep short and also space for a second additional row keep clear if the amount of offset of additional row opposite the row less than half the distance two recesses of the row to each other.
  • the number of peaks can be changed according to another advantageous development of the invention particularly low hold when the recesses of the additional row in the Recesses of the row continuous or stepped pass.
  • a reliable separation of the row of recesses of the additional series of recesses can be arranged according to another advantageous embodiment of the invention simple reach when the amount at an angle of the recesses from 90 ° is 0.6 to 1 mm.
  • Steep flanks between the recesses of the row and the additional series can be according to another advantageous Simply avoid development of the invention if a difference in the height of adjacent recesses the row and the auxiliary row less than half this amount is.
  • the second problem namely the creation of a as simple as possible built locking system for several Hierarchy levels is achieved according to the invention, that the distance of the stop of the lock cylinder too the pin tumblers in the one hierarchy level greater is as in the other hierarchical level and that the Key offset one from the row of recesses arranged additional row of recesses has.
  • the one hierarchical level of the Pin tumblers assigned a different set of recesses as the other hierarchical level. This can be done several hierarchical levels through the appropriate choice of corresponding to each other attacks the key and easily create the lock cylinder. Further points the locking system according to the invention a high security against unauthorized unlocking the lock cylinder on, since the keys and thus the lock cylinder within a hierarchical level in the entire additional series can distinguish. Construction pins or the design the profile of the shaft according to the known locking systems can supplement the further increase in hierarchy levels be used.
  • FIG. 1 shows a lock cylinder 1a with a key 2a.
  • the key 2a has a shaft 3 with which he in a closing channel 4 of a rotatable in a housing 5 Kerns 6 of the lock cylinder 1a penetrates.
  • his lateral shaft portion has the key 2a a Locking channel 4 corresponding key profile 7.
  • Im Chest section of the key 2a is a row 8 of Pin tumblers 9 of the lock cylinder 1a opposite Recesses 10 arranged.
  • the lock cylinder 1a and the key 2a each have a stop 11, 12, with the recesses 10 against the Stiftzuiensen 9 are aligned.
  • the recesses 10 move the pin tumblers 9 in a position in which the parting planes two pins 13, 14 with the parting plane of the core 6 and of the housing 5 coincide.
  • the core 6 can be rotated with it become.
  • FIGS. 2 to 4 each show a lock cylinder 1b - 1d with a key 2b - 2d another hierarchical level.
  • the stop 11 'for the key 2b - 2d by the amount A staggered.
  • the keys 2b - 2d have in addition to the key 2a of Figure 1 corresponding Row 8 of recesses 10 one pin tumblers 17 oppositely arranged additional row 15th of recesses 16. Row 8 of recesses 10 and the additional row 16 are offset by the amount A.
  • the key 2a of Figure 1 does not have the pin tumblers 17 of the lock cylinder 1b - 1d from the figures 2 to 4 corresponding recesses.
  • the lock cylinders 1b - 1d from Figures 2 to 4 can therefore be do not unlock with the key 2a of FIG.
  • the keys 2b - distinguish 2d from Figures 2 to 4 each other in a pin tumbler 17 and a recess 16 in the additional row 15 of the key 2b - 2d. This will ensure that each two of the pin tumblers 17 a rotation of the core. 6 prevent, for example, the key 2b of FIG 2 introduced into the lock cylinder 1c of Figure 3 becomes.
  • the additional row 15 of the recesses 16 the Pin tumblers 17 opposing projections.
  • Figure 3 shows that the difference in the depth of two adjacent recesses 10, 16 of the series 8 and the additional row 15 also corresponds to the amount A to the the stops 11, 11 'and the row 8 and the additional row 15 are offset from each other.
  • the difference of depth can at the illustrated notch angle of the recesses 10, 16 by 90 ° also be smaller than A.
  • the dimension A shown in the embodiment with respect to the offset of the lock cylinder side stops 11, 11 'and the recesses 10, 16 in the row 8 and the additional row 15 is fictitious and is for example at a notch angle of the recesses 10, 16 of 90 ° 0.6 up to 1 mm.
  • the measure can also be A / 2, and additional hierarchical levels can be added not shown additional rows of recesses provide.
  • the known locking system or a known variation of Profile of the shaft of the key 2a - 2d inserted become. Notwithstanding the illustrated stepped Transition of two adjacent recesses 10, 16 of the series 8 and the additional row 15, the recesses 10, 16 continuously merge into each other or additional, not shown pointed notch-shaped recesses be provided.
