Definitions

  • the invention relates to a locking cylinder for a key with a core that can be moved in a housing, with a locking channel arranged in the core for receiving a shaft of a key, with locking elements that can be moved from locking recesses in the key for selectively locking or releasing the movement of the core, with a first, in a central plane leading longitudinally through the locking channel of parallel recesses for receiving at least a portion of the locking elements, the locking elements being biased in the direction of the locking channel for active interrogation types or held movably in the core without preload for passive interrogation types.
  • the blocking elements can directly block the movement of the core itself or can scan the key and move another blocking element into a position blocking the movement of the core.
  • the locking elements can be designed as pin tumblers with a core pin and a housing pin or can only have a core element.
  • a cylinder lock with a cylinder housing and a cylinder core is, for example, from the EP 0 115 568 A2 known.
  • this cylinder lock several locking elements for active query types and for passive query types are grouped around the locking channel.
  • the locking elements of the active query types which are preloaded by spring elements, protrude vertically into the locking channel.
  • Blocking elements of passive query types are arranged in the corner areas of the locking channel.
  • a locking device in which further recesses are arranged laterally next to the locking channel parallel to the central plane of the locking channel.
  • the recesses each have core pins and housing pins preloaded by spring elements. Blocking elements for passive query types are not provided.
  • the disadvantage of the known locking cylinders is that changing the query types requires a great deal of structural effort.
  • the combination of different query types offers a high level of security, particularly with regard to copy protection of the key provided for closing the locking cylinder.
  • the invention is based on the problem of developing a locking cylinder of the type mentioned in such a way that it has a particularly high degree of variability and a high number of query types.
  • the lock cylinder has a large number of recesses in which locking elements for active or passive types of query can be used. Due to the large number of recesses, the locking cylinder also has a large number of locking secrets. The locking cylinder therefore offers a high level of security against unauthorized unlocking, as it is not visible from outside at which point on the key an active or passive query type is required.
  • a particularly high number of query types can be easily arranged in the locking cylinder with limited installation space if the recesses in the first row and the second row have the same distances from one another, with the second row being half as large as the first row Distance between the recesses is offset.
  • the locking elements deflected by the key enable the control of a common locking element if the core has an elongated recess for a strip-like locking element and if the elongated recess is arranged perpendicular to the second row of parallel recesses.
  • the locking elements arranged in the second row could, like the locking elements arranged in the first row, be individually movable relative to a locking recess in the housing.
  • a particularly large area of support for the core relative to the housing can be easily achieved if the locking elements arranged in the second row of recesses have lateral slots and if the slots have the height of the strip-like locking element.
  • the invention contributes to simplifying the assembly of the locking cylinder if the locking elements arranged in the second row are prestressed by spring elements, if a common holding rod supports the spring elements and if the holding rod is fastened in the core.
  • the holding rod is preferably pressed into the core.
  • the locking cylinder has a particularly simple construction if the strip-like locking element is biased by a spring element in the direction of the housing and if the strip-like locking element and a locking recess in the housing are designed in a ramp-like manner relative to one another.
  • the ramp-like design of the strip-like locking element and the locking recess enable the strip-like locking element to be pushed back into the core when the core rotates when the movement is released.
  • the invention contributes to further increasing the modular diversity of the locking cylinder if a locking element projecting into the locking channel is arranged in the connection between two recesses guided to the outside of the core.
  • active and passive query types can be provided and used through a suitable choice of blocking elements.
  • the locking cylinder has a particularly high level of security against unauthorized unlocking if one of the locking elements prestressed into the locking channel has an undercut and is guided in the housing up to just before a locking recess and if a locking element prestressed transversely thereto has a partial area penetrates into the undercut using a deflection ramp.
  • the undercut is preferably created by a circumferential constriction of the locking element.
  • the locking element can have a cylindrical or spherical shape.
  • the invention contributes to increasing the variety of query types if a further locking element is arranged in each of the recesses leading to the outside of the core to the locking element projecting into the closing channel. As a result, the position of the locking element protruding into the locking channel is scanned by two further locking elements at the same time.
  • the invention contributes to further increasing the modular diversity of the locking cylinder if a third row of recesses is arranged next to the locking channel and if the first row of recesses is arranged between the second row of recesses and the third row of recesses is.
  • locking elements arranged in the third row of recesses also control a strip-like locking element, so that the locking cylinder is constructed essentially symmetrically, apart from individual passive types of query.
  • Figure 1 shows a lock cylinder 1 with a core 3 that can be rotated in a housing 2 and with a key 4 authorized to close in a sectional view along a central plane.
  • the locking cylinder 1 has a locking channel 5 and a first row of locking elements 6, for selectively blocking or releasing the movement of the core 3.
  • the locking elements 6 are biased by spring elements 7 into the locking channel 5 and thus into locking recesses 8 in the key 4.
  • the locking recesses 8 for the first row of locking elements 6 are arranged in a key chest 9 of the key 4.
  • the locking elements 6 are therefore part of active query types of the locking cylinder 1.
  • the housing 2 and the core 3 have a series of recesses 10.
  • FIG 2 shows a sectional view through the lock cylinder 1 Figure 1 along the line II - II.
  • the locking cylinder 1 has a second row of locking elements 11 and a third row of locking elements 12, which are arranged next to the locking channel 5 and thus next to the central plane of the locking cylinder 1.
  • These locking elements 11, 12 penetrate into the locking channel 5 from the side and feel Locking recesses 15, 16 arranged on the broad sides 13, 14 of the key 4.
  • a comparison of the Figures 1 and 2 shows that the locking elements 6 of the first row and the locking elements 11, 12 of the second and third rows have the same distances from one another, the second row being offset from the first row by half the distance of the locking elements 6, 11, 12.
  • Figure 3 shows a sectional view through the lock cylinder Figure 2 along the line III - III, that locking elements 11 ', 12 of the second and third rows arranged in the sectional plane face further locking elements 17, 18 with a deflection ramp 19, 20.
  • the further locking elements 17, 18 with a deflection ramp 19, 20 are prestressed by spring elements 21, 22 and are guided displaceably parallel to the second and third rows of recesses 23, 241 arranged in the central plane.
  • the spring elements 21, 22 are supported on a holding rod 25, 26 pressed into the core 3.
  • the locking elements 11 ', 12 prestressed in the closing channel 5 are arranged in a connection between two recesses 23, 24, 27, 28 which extend to the outside of the core 3.
  • One of the locking elements 11 'prestressed into the locking channel 5 has an undercut 29 and is guided in the housing 2 until just before a locking recess 30. This undercut 29 is scanned by the locking element 11 'having the deflection ramp 19.
  • the locking elements 17, 18 having the deflection ramp 19 have side slots 37, 38 for strip-like locking elements 31, 32.
  • the strip-like locking elements 31, 32 are guided displaceably in recesses 33, 34 arranged parallel to the central plane and are each biased into a locking recess 35, 33 in the housing 2.
  • the strip-like locking elements 31, 32 and the associated locking recesses 35, 36 are designed in a ramp-like manner relative to one another, so that when the core 3 rotates relative to the housing 2, they can be pushed back into the core 3 as soon as the side slots 37, 38 of the deflection ramp 19 , 20 having locking elements 17, 18 are moved at the height of the strip-like locking elements 31, 32.
  • FIG 4 shows a sectional view through the lock cylinder 1 Figure 2 along the line VI - VI that a further locking element 39 is arranged in a recess 28 'leading to the outside of the core 3 behind a locking element 12' which scans the key.
  • This locking element 39 faces a locking recess 40 in the housing 2 and is intended for a passive type of query. If the key 4 has a correspondingly deep locking recess 16 'into which the next locking element 12' can penetrate, the locking element 39 opposite the locking recess 40 can also dip into the core 3. The core 3 can then be rotated relative to the housing 2 without hindrance.
  • Figure 5 shows a sectional view through the lock cylinder 1 Figure 2 along the line V - V that a further blocking element 41 is displaceably arranged in a recess 42 in the core 3.
  • This further locking element 41 scans a web 43 of the key 4 without bias and is therefore part of a passive type of query.
  • Spring elements 44 for pretensioning the strip-like locking elements 29, 30 in the direction of the locking recesses 33, 34 in the housing 2.
  • Figure 6 For clarity, shows the locking elements and the spring elements of the locking cylinder from the Figures 1 to 5 in a perspective view. To simplify the drawing, only the locking elements 6, 11, 12, 17, 18, 31, 32, 39, 41 guided in the core 3 are shown. The holding rods 25, 26 for the locking elements 17, 18 arranged laterally next to the central plane are guided over the entire respective row of locking elements 17, 18.
