11101 4 -86 : Locking device [0] with a large [1-2] number [-1] of [-1] locking [-1] combinations [-1] . [4]
1111101111111111111111111111011111111011111111111111111111111111111111111111111 78 -42 : The invention relates to a [0-4] locking device [9-10] which [11-12] consists [-1] of [26-27] a [31-33] lock [35-36] and [29-30] key [13-14] and [6-7] which [8] has [19-20] tumblers [18] transferable [-1] into [55-58] the [62-65] release position [59-60] by means [52] of [49-50] the [46-47] key [51] and [40] , [38-39] particularly [22] for a large [23-25] number [-1] of [34] lock [-1] combinations [-1] , [61] proposes [-1] that [-1] at least one [66-67] of the [69-70] tumblers [-1] ( [73] 20 [-1] ) [75] , [77] in [-1] addition [-1] to [-1] or [-1] alternatively to [41-42] its [43] direct control [44-45] by [-1] the [-1] basic code [48] of [-1] the [-1] corresponding [-1] key [-1] , [21] can be [17] brought [-1] into the release position [15-16] by [-1] means [-1] of a magnetic coil [53-54] ( [-1] 43 [-1] ) [-1] which [-1] can [-1] be energised [76] by [-1] a [-1] reading device [72] ( [-1] 44 ) [74] detecting [71] at [-1] least [-1] one [-1] supplementary code [68] of [-1] the [-1] key [-1] . [78]
111111111111111111111 20 72 : The present invention relates to a [0-3] locking [9] device which consists of a lock [4-5] and a key [6-7] and [8] which [10-11] has [19] tumblers [18] that can be [17] brought [-1] into a release position [15-16] by [12] the key [13-14] . [20]
11111 4 96 : Such [0] locking devices [1] are known . [2-4]
1111111111111011111 12 -74 : They [0] can be formed [16-18] , [10-11] for [-1] instance [-1] , [8-9] of [2-3] locking [7] cylinders [-1] which [6] can be [1] locked [-1] by [4] flat keys [5] or [-1] else [-1] also [-1] of [-1] locking devices [15] which [14] are [-1] operated [-1] with [12] magnetic [-1] keys [-1] . [-1]
111100111110101111111111111111 29 -25 : All [0] of [6-10] these [1] locking devices [2] share [-1] the [19-20] common [-1] feature [-1] that [-1] while [-1] the [23-24] number [-1] of [16-17] locking [-1] combinations [-1] is [3] frequently [12] considerable [14-15] , [18] this [-1] number [-1] however [-1] , could be [27-28] further increased [25-26] in order to increase [21-22] security [-1] . [29]
1111111101111111111111111111111 30 71 : Particularly [0] with respect to [1-3] locking systems [4] having [5] master [-1] and [6-7] specific [-1] keys [9] there is [10] a need [11-13] to make available [21-24] in [14] a locking system [15-16] a [17] large number of [18-19] keys [20] which have different [25-27] access authorizations [28] . [29-30]
10111111111111111111111111111 28 66 : Such [2-3] locking systems [4] frequently [0] have the disadvantage that [5-8] the [9-10] main [-1] master [-1] key [11] which [12-13] can be used [19-20] for all locks [14-16] of the locking system [17-18] has [27] only [21-22] a relatively [23-24] simple coding [25-26] . [28]
111111111111111111011111111110111110011111111101111 50 8 : In the case of [0-3] locking devices [4] which [5-6] are used [11-12] by [7] continuously changing [8-9] users [10] ( for instance [13-16] , [22-23] in [17] hotels [-1] ) [19-21] , [37-38] it [40] is [27] necessary [-1] to ensure that [24-26] the [28] previous [-1] user [-1] cannot [30-31] easily [32] obtain [-1] a [33-34] copy [-1] of the [39] key [-1] , [-1] which [-1] would [-1] raise [-1] the [44] possibility [-1] of [-1] his [-1] unauthorized [41] access into the [42-43] room [48] inhabited [47] by the [45] subsequent [-1] user [-1] . [49-50]
1111001111101111110111111111 27 44 : In many known [0-2] locking devices [3] an increase in the number of [6-10] locking [-1] combinations [-1] also [12] means [-1] an [13] increase in the [15-16] structural [14] size [-1] of the [24] key [17] , which has a [19-21] detrimental effect on [22-23] convenience [25] .
