  • the scanning element of the locking core is designed as a scanning element described here.
  • a locking core with a profiled locking channel and core pin hole, also with core pins and housing pins, generally with locking pins but without a receiving space, is basically known from the prior art.
  • the receiving space is designed to accommodate a scanning element.
  • the receiving space is adapted to the contour of the scanning element, with tolerances being provided so that the scanning element can be moved within the receiving space at least in one direction, preferably an axial direction, of the core bore.
  • the receiving space has a base space that is adapted to the base body of the scanning element, and a projection space that is adapted to the tactile projection or tactile projections.
  • the receiving space and the projection space are dimensioned larger in the axial direction of the core hole than the base body or the respective sensing projection, so that a degree of freedom for movement of the scanning element in the axial direction of the core bore is possible.
  • 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 is thus formed for a stroke of the scanning element.
  • the projection space breaks through into the locking channel, so that an (undercut) profile rib of an inserted profiled key can or projects through the locking channel into the projection space, more precisely into a sensing space which is defined in the axial direction of the core bore by the scanning dimension.
  • the projection space and/or the scanning space breaks through laterally into the closing channel by at least 8 percent of the total length of the projection space and/or the scanning space.
  • the lateral breakthrough is at least 10 percent, preferably at least 15 percent, even more preferably at least 20 percent and most preferably at least 40 percent of the total length of the projection space and/or the scanning space.
  • the projection space/scanning space breaks through laterally into the locking channel.
  • the scanning dimension or the scanning space is dimensioned such that when a key is inserted with a sufficiently undercut profile rib, the profile rib projects into the scanning space, in particular protrudes laterally into the scanning space, and when the scanning projection protrudes into the scanning space sufficiently undercut profile rib of the key, the outside of the base body at least in the area of the core pin hole is flush with the outer contour of the area of the housing pin and / or cylinder housing surrounding the core pin hole closes so that the housing pin is prevented from penetrating into the receiving space.
  • the front part of the profile rib protrudes from the tip to the undercut, more precisely with an overhang of the undercut profile rib into the tactile area.
  • the profile rib When used in the closing channel in the axial direction of the core bore, the profile rib has a profile dimension which is smaller or equal to, preferably approximately in the order of magnitude of the scanning dimension and smaller. Accordingly, the part of the profile rib between the tip or outer end and the undercut can protrude into the scanning space and be scanned there by the scanning element. Due to the undercut, an excess, projection or overhang of the profile rib is formed at the tip of the profile rib, which is queried or scanned in the scanning space.
  • the sensing space is therefore not or only insufficiently occupied by the profile rib or the sensing projection does not strike the profile rib but rather the end wall of the projection space away from the base space.
  • the base body therefore also borders on an inner wall of the receiving space and the flanks of the receiving space create an offset in the area of the locking pin, more precisely the housing pin, around which the housing pin can penetrate into the receiving space. This prevents the locking core from rotating in the cylinder bore of the locking cylinder beyond a certain angle of rotation when used in the locking cylinder. The angle of rotation is determined by the size of the recording space.
  • the present invention allows the locking core to rotate back and not be caught in its twisted position.
  • Sufficiently undercut therefore describes an overhang formed by an undercut, which occupies a scanning space in such a way that an adjacent scanning element inhibits rotation of the locking core from a predetermined angle of rotation.
  • Such undercuts or corresponding overhangs have a dimension in the axial direction of the core pin bore which is preferably over 0.1 mm, more preferably over 0.2 mm and most preferably over 0.3 mm.
  • the dimension is preferably smaller than 5 mm, more preferably smaller than 4 mm and most preferably smaller than 3 mm.
  • An undercut profile rib is therefore always to be understood as a sufficiently undercut profile rib that has an overhang which the touch function can be implemented.
  • the rib preferably protrudes through the side opening into the scanning space/protrusion space.
  • the scanning element of the locking core is designed according to a scanning element described above.
  • the receiving space of the locking core is adapted to the scanning element for receiving the scanning element with provision of the scanning space and movement back and away to the scanning space.
  • the receiving space is preferably designed to be complementary to the scanning element, but also has the scanning dimension or the stroke, that is to say it is larger in the axial direction of the core bore than the scanning element or the scanning projection. This allows a linear movement in the axial direction of the core hole.
  • the invention includes the technical teaching that in a scanning mechanism for a locking cylinder, with a locking core which has a locking channel into which a corresponding key can be inserted, which has at least one core pin hole designed as a through opening and which has a receiving space in which a scanning element is accommodated, it is provided that the scanning element has a core pin receptacle aligned with the core pin bore, a core pin being receivable and/or accommodated in the at least one core pin bore and the core pin receptacle, the receiving space forming a sensing space which breaks through into the locking channel or protrudes into the locking channel, so that a corresponding key section of a key inserted into the locking channel protrudes or can protrude into the sensing space, so that the scanning element in the area of the sensing space strikes or can strike against the corresponding key section protruding into the sensing space, the sensing space being dimensioned in this way that if the corresponding key section has a sufficiently undercut profile rib, the scanning element

  • a shoulder is formed in the area of the outside of the base body to the adjacent circumference of the cylinder core, so that the housing pin can partially penetrate into the receiving space and a rotational movement is blocked by abutting the flanks of the receiving space from a predetermined angle of rotation.
  • the locking core cannot be rotated further in a direction to open, but only back to the starting position in which the key was inserted into the locking channel.
  • the receiving space is preferably designed symmetrically to the core bore, so that rotation in and counterclockwise is possible, limited by the corresponding dimension of the receiving space.

  • the scanning element 180 has a base body 181, from the inside of which two sensing projections 182 protrude approximately vertically.
  • the tactile projections 182 are cylindrical.
  • the tactile projections 182 are arranged diametrically opposite and spaced apart from one another on the inside.
  • the base body 181 has the receptacle 183 centrally for receiving the core pin 21.
  • the receptacle 183 designed as a through hole, penetrates the base body 181 from a front side section 184 of the outside 185 towards the inside 189.
  • a bevel 186 On the side of the outside 185 on each side there is a bevel 186, which is beveled at a first angle a to the front side section 184 adjacent. This is followed by another bevel 187, which is beveled at a second angle b. Due to the multiple bevels 186, 187, the scanning element 180 is optimized for contact with the housing pin 23 or an inner wall of the cylinder bore 120. In other embodiments, multiple slopes 186, 187 may be provided.
  • Fig. 9 shows the embodiment schematically in a side view 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.
  • the front one Page section is marked 184.
  • the inside is marked 189.
  • the two different sized angles a and b of the slopes 186, 187 are also shown.
  • Fig. 10 shows schematically in a side view another embodiment of the scanning element 180.
  • the in Fig. 10 The scanning element 180 shown has, instead of the two bevels 186, 187, a rounded surface 186a with a radius R, which adjoins the front side section 184.
  • Several differently rounded surfaces 186a with different radii R can also be provided.
  • Fig. 11 shows schematically the locking cylinder 100 in a sectioned front view Fig. 1 with a key 10 with an undercut profile rib 15a in a starting position and in a twisted position.
  • the front part of the undercut profile rib 15 of the key 10 projects through the locking channel 150 over the opening into the scanning space 176.
  • the undercut profile rib 15a with the formed oblique projection, more precisely with the overhang 15b presses against the sensing projection 182 of the scanning element 180
  • the scanning element 180 is pressed outwards accordingly and is thus flush with the outer contour of the locking core 130.
  • the core pin 21 is flush with the scanning element 180, so that the core pin 21 can rotate with the locking core 130, as shown on the right Fig. 11 shown based on the twisted 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 such that it forces the scanning element 180 outwards accordingly, so that the locking core 130 can be rotated. Without this (sufficiently dimensioned) overhang 15b, twisting is only possible to a limited extent, as shown Fig. 12 visible.
  • Fig. 12 shows schematically the locking cylinder 100 in a sectioned front view Fig.1 with a key 10 without (sufficiently) undercut profile rib 15a in a starting position and in a twisted position.
  • the tactile projection 182 is not the (insufficiently undercut) profile rib 15.
  • the significance of the missing overhang 15b becomes apparent in the twisted situation. Due to the missing overhang 15b, the forward stop for the scanning element 180 is missing.
  • the scanning projection 182 is forced further inwards, so that the core pin 21 protrudes beyond the scanning element 180 and an offset 179 is formed on the receiving space 170, in which the locking core 130 forced housing pin 23 penetrates.
  • the angle of rotation c can be adjusted via the geometry of the recording space 170 together with the scanning element 180. The following figures make it clear how the dimensions are to be determined to achieve the scanning function.
  • Fig. 13 shows schematically in a sectioned front view an embodiment of a locking core 130 with receiving space 170, base space 172, projection space 174, scanning space 176 and locking channel 150 according to Fig. 6 by 180° Fig. 6 turned.
  • Fig. 14 shows schematically in a front view an embodiment of the scanning element 180.
  • Fig. 15 shows schematically in a sectioned front view a key profile of the key 10 with a (sufficiently) undercut profile rib 15a, that is to say with an overhang 15b.
  • Fig. 16 shows schematically the embodiment in a sectioned front view Fig. 11 in a starting position and in a twisted position. The steps for determining are numbered in the figures.
  • D denotes the height of the projection space 174 from a constructive center line of the closing 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 of the projection space 174 in the axial direction.
  • F denotes the Total height of the scanning element 170 in the axial direction of the core (pin) bore 160.
  • G denotes the height of the sensing projection 182 in the axial direction of the core pin bore 160.
  • I denotes a width or key shaft 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 in the axial direction of the core pin bore 160, which, in contrast to a non-undercut profile rib 15, results from the undercut 17 and which determines the height of the stroke and thus the scanning dimension A.
  • 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 equal to, preferably slightly larger than, the dimension H in order to ensure that an offset is guaranteed if the profile rib 15 is not sufficiently undercut.
  • H+ is approximately in the order of magnitude of H or A, possibly a tolerance level higher. As in Fig. 16 can be seen in the twisted position on the right, the dimension H can be found 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 locking core 130. H+ is preferably less than 20%, preferably less than 15% and preferably less than 10% larger than H.
  • the aforementioned variables determine the scanning function. Starting from an (inner diameter) diameter J of the closing core 130, the maximum width of the receiving space 170 must be determined. Depending on the depth of the receiving space 170, the corresponding depth of the base body 181 located therein can be determined. The offset or the flank height and thus also the stroke H also depend on the width and depth of the receiving space, which ultimately also determines the overhang 15b.
  • Fig. 17 shows schematically the exemplary embodiment of a locking core in a perspective view Fig. 2 with a scanning element 180 adapted to production technology.
  • the 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 on each tactile projection 182.
  • the recesses 191, 192 are formed directly on the side edges, so that they break through them at the respective side edges and thus a recess 191, 192 that is open to at least one side is realized.
  • the recesses 192 on the tactile projections 182 form a kind of chamfer at the tip of the respective tactile projection.
  • Fig. 18 shows schematically in a perspective view the in Fig. 17 shown, production-technically adapted scanning element 180 alone.
  • the recesses 190 for the sprue and overflow can be clearly seen here.
  • Each tactile projection 182 has a recess 192 at the end remote from the base body 181.
  • the base body 181 has two diametrically opposed recesses 192.
  • Fig. 19 shows schematically in a different perspective view the in 17 and 18 shown, production-technically adapted scanning element 180. Except for the recesses 190, this corresponds to the Fig. 17 to 19
  • the scanning element 180 shown corresponds to the scanning element 180 shown in the previous figures.
  • the recesses 192 can be clearly seen at the end of the tactile projections 182 remote from the base body 181. Due to the cylindrical design of the tactile projections 182, these are designed in a bevel-like manner.
