  • the receiving space in the axial direction of the core bore is dimensioned to be one scanning dimension larger than the corresponding area of the scanning element. A space for a stroke of the scanning element is thus formed.

  • a bevel 186 which is beveled at a first angle a on the front side section 184 adjoins.
  • a further bevel 187 which is beveled at a second angle b.
  • the sensing element 180 is optimized for contact with the housing pin 23 or an inner wall of the cylinder bore 120.
  • multiple slopes 186, 187 can be provided.
  • Fig. 9 shows schematically in a side view the embodiment according to Fig. 8 .
  • the contour of the base body 180 with the two bevels 186, 187, which is adapted to the circular cylindrical contour of the cylinder bore 120, can be clearly seen here.
  • the front side section is labeled 184.
  • the inside is marked with 189.
  • the two differently large angles a and b of the slopes 186, 187 are also shown.
  • Fig. 10 schematically shows another embodiment of the scanning element 180 in a side view Fig. 10
  • the scanning element 180 shown has a rounded surface 186a with a radius R, which adjoins the front side section 184 in each case.
  • Several differently rounded surfaces 186a with different radii R can also be provided.
  • Fig. 11 shows schematically in a sectional front view the lock cylinder 100 according to FIG Fig. 1 with a key 10 with an undercut profile rib 15a in one Starting position and in a twisted position.
  • the front part of the undercut profile rib 15 of the key 10 protrudes through the locking channel 150 over the opening into the scanning space 176.
  • the undercut profile rib 15a with the sloping projection presses against the scanning projection 182 of the scanning element 180
  • the sensing element 180 is correspondingly pressed outwards and is thus flush with the outer contour of the closing core 130.
  • the core pin 21 ends flush with the sensing element 180, so that the core pin 21 can be rotated with the lock core 130, as shown on the right in FIG Fig. 11 shown based on the rotated position.
  • the overhang 15b of the (sufficiently) undercut profile rib 15a which is formed between the tip of the profile rib 15a and the undercut 17 of the profile rib 15a, is dimensioned in such a way that it forces the sensing element 180 outwardly so that the lock core 130 can rotate. Without this (sufficiently dimensioned) overhang 15b, rotation is only possible to a limited extent, as shown in FIG Fig. 12 evident.
  • Fig. 12 shows schematically in a sectional front view the lock cylinder 100 according to FIG Fig. 1 with a key 10 without (sufficiently) undercut profile rib 15a in a starting position and in a twisted position.
  • the starting position the situation is similar to that in the starting position in Fig. 11 .
  • the feeler projection 182 does not contact the (insufficiently undercut) profile rib 15.
  • the importance of the missing overhang 15b becomes apparent. Due to the missing overhang 15b, the forwardly displaced stop for the scanning element 180 is missing.
  • the scanning projection 182 is forced further inward so that the core pin 21 protrudes over the scanning element 180 and an offset 179 is formed in the receiving space 170, in which the key against the lock core 130 forced housing pin 23 penetrates. This penetration of the housing pin 23 prevents further rotation beyond the predetermined rotation angle c.
  • the angle of rotation c can be set together with the scanning element 180 via the geometry of the receiving space 170.
  • Fig. 13 shows schematically in a sectional front view an embodiment of a lock core 130 with receiving space 170, base space 172, projection space 174, scanning space 176 and locking channel 150 according to FIG Fig. 6 by 180 ° Fig. 6 turned.
  • Fig. 14 shows schematically an embodiment of the scanning element 180 in a front view.
  • Fig. 15 shows schematically in a sectional front view a key profile of the key 10 with (sufficiently) undercut profile rib 15a, that is to say with overhang 15b.
  • Fig. 16 shows schematically in a sectional front view the embodiment according to FIG Fig. 11 in a starting position and in a twisted position. The steps for determining are numbered consecutively in the figures.
  • D denotes the height of the projection space 174 from a structural center line of the lock core 130 in the axial direction of the core (pin) bore 160 to the stop at the end of the projection space 174.
  • E denotes the length dimension of the projection space 174 in the axial direction.
  • F denotes the Total height of the sensing element 170 in the axial direction of the core (pin) bore 160.
  • G denotes the height of the feeler projection 182 in the axial direction of the core pin bore 160.
  • I denotes a width or also key shank height I of the key 10 in the axial direction of the core pin bore 160, more precisely of the key profile.
  • H denotes the height of the overhang 15b, which, in contrast to a non-undercut profile rib 15, results from the undercut 17 and which defines the height of the stroke and thus the scanning dimension A.
  • the overhang 15b is absent, which is why the scanning element 180 can be moved by a stroke H in the receiving space 170.
  • the receiving space 170 has the dimension H + in the axial direction of the core pin bore 160, i.e. a dimension H increased by a tolerance. This dimension H + should be at least the same, preferably slightly greater than the dimension H in order to ensure that an offset is not sufficiently undercut Profile rib 15 is guaranteed.
  • H + is roughly in the order of magnitude of H or A, possibly by a tolerance level above. As in Fig. 16 can be seen in the rotated position on the right, the dimension H is found again as an offset 179 on the receiving space 170. The housing pin 23 can penetrate into the receiving space 170 by this offset 179 and thus block further rotation of the lock core 130. H + is preferably less than 20%, preferably less than 15% and preferably less than 10% greater than H.
  • the aforementioned variables determine the scanning function. Starting from an (inner diameter) diameter J of the lock core 130, the maximum width of the receiving space 170 is to be determined. Depending on the depth of the receiving space 170, the corresponding depth of the base body 181 inserted therein can be determined. The offset or the flank height and thus also the stroke H are also dependent on the width and depth of the receiving space, which ultimately also determines the overhang 15b.
  • Fig. 17 shows schematically in a perspective view the embodiment of a lock core according to FIG Fig. 2 with scanning element 180 adapted in terms of manufacturing technology.
  • scanning element 180 is manufactured in one piece as a die-cast part.
  • the scanning element 180 therefore has recesses 190 for the sprue and overflow during die casting.
  • two recesses 191 are provided on the base body 181 and one recess 192 each on each probe projection 182.
  • the recesses 191, 192 are formed directly on the side edges, so that they break through at the respective side edges and thus a recess 191, 192, which is open at least on one side, is implemented in each case.
  • the recesses 192 on the feeler projections 182 thus form a type of bevel at the tip of the respective feeler projection.
  • Fig. 18 shows schematically in a perspective view that in Fig. 17 illustrated, manufacturing technology adapted scanning element 180 on its own.
  • the recesses 190 for the sprue and overflow can be clearly seen here.
  • Each sensing projection 182 has a recess 192 at the end remote from the base body 181.
  • the base body 181 has two diametrically opposite recesses 192.
  • Fig. 19 shows schematically in another perspective view the in FIG Figures 17 and 18
  • the scanning element 180 shown adapted in terms of manufacturing technology. Except for the recesses 190, this corresponds to FIG Figures 17 to 19
  • the scanning element 180 shown corresponds to the scanning element 180 shown in the previous figures Fig. 19 the recesses 192 at the end of the feeler projections 182 remote from the base body 181 can be clearly seen. Due to the cylindrical design of the feeler projections 182, these are chamfer-like.
