Definitions

  • the invention relates to a lock cylinder with a rotatable core in a housing with pin tumblers for selectively blocking or releasing the movement of the core, with a cam, with a locking channel arranged in the core for introducing a key for driving the Stiftzuiensen and for moving a coupling sleeve between a relative to the cam in the direction of rotation released position and connected to the cam in the rotational direction position, wherein the coupling sleeve has a form-fitting recess for generating a positive connection with the key.
  • Such a lock cylinder is for example from the DE 35 02 860 A1 known.
  • the lock cylinder has a freewheel of the cam and ensures that after deduction of the key from the lock channel, the movement of the cam is released and is not blocked by the fixed core. This requires that a positive connection of the locking bit indirectly via the coupling sleeve with the core via the key.
  • the coupling sleeve is accessible through the closing channel. In the worst case, it is possible to attack the coupling sleeve with a manipulation tool through the closing channel and to turn the cam. This allows unauthorized closing of the lock cylinder.
  • the invention is based on the problem of designing a lock cylinder of the type mentioned above so that it is as reliable as possible against manipulation.
  • the core has on its the front side facing the cam facing a center of the front side covering the bottom and that the core has an aligned with the Form gleichausströmung the coupling sleeve opening.
  • the movement of the coupling sleeve by a manipulation tool introduced into the closing channel can be made more difficult according to an advantageous development of the invention if the form-fitting recess and the opening are slot-shaped and have the width of the closing channel.
  • the engagement surface of the coupling sleeve for applying a manipulation tool can be kept particularly small according to another advantageous embodiment of the invention, when the core is cup-shaped with a jacket adjacent to the bottom and the opening is arranged on the jacket.
  • the lock cylinder according to the invention can be easily mounted axially according to another advantageous embodiment of the invention, when the opening of the jacket is guided into the region of the bottom immediately adjacent to the jacket.
  • a reliable power transmission from the inserted into the lock channel key on the coupling sleeve can be easily ensured according to another advantageous embodiment of the invention, when the coupling sleeve surrounds the bottom of the core.
  • a tilting of the components of the lock cylinder according to the invention can be easily avoided according to another advantageous embodiment of the invention, when the coupling sleeve is guided in an end groove of the core.
  • the lock cylinder according to the invention is structurally particularly simple if the bottom covering the center of the end face of the core fills the area radially inside the groove.
  • existing cores can be simply retrofitted with the floor according to the invention if the center of the Front of the core overlapping bottom is produced by a plug connected to the core.
  • An introduced into the lock channel manipulation tool has according to another advantageous embodiment of the invention, only a very small contact surface on the coupling sleeve when the wall thickness of the coupling sleeve has smaller dimensions than the distance between two profile grooves in the closing channel. This leads to a further complication of unauthorized closing of the lock cylinder according to the invention.
  • the positive connection of the inserted into the lock channel key with the coupling sleeve is capable of transmitting particularly high forces according to another advantageous embodiment of the invention, when the coupling sleeve is guided into the radially outermost profiled groove of the closing channel.
  • the coupling sleeve is supported in the authorized closing of the lock cylinder according to the invention at the outermost protruding rib.
  • the contact surface of the coupling sleeve can be further increased if the wall thickness of the coupling sleeve extends beyond that of the radially outermost profiled groove to the next profile groove.
  • the lock cylinder according to the invention can be closed particularly comfortably when the form-fitting recess is designed to widen conically in the radially outward-pointing direction.
  • FIG. 1 shows a double-profile lock cylinder with two rotatable in a housing 1 cores 2, 3.
  • the cores 2, 3 are in the basic position of pin tumblers 4 with the Housing 1 rotatably connected and can be rotated by means of a introduced into a closing channel 5, authorized to close key 6 relative to the housing 1.
  • a cam 7 is rotatably arranged.
  • Between the cores 2, 3 and the cam 7 each have a coupling sleeve 8 is arranged axially displaceable.
  • the coupling sleeves 8 are by means of a spring element 9 away from each other and thus biased to the cores 2, 3.
  • the coupling sleeves 8 rotatably with the cam 7, but rotatably held in the basic position with respect to the cores 2, 3.
  • the coupling sleeves 8 create a positive connection between the tip of the inserted into the lock channel 5 key 6 and the cam 7. If in a position not shown, no key 6 is inserted into the lock cylinder, the cores 2, 3 on the Stiftzunnenen 4 with the housing 1 rotatably connected.
  • the cam 7 can be rotated together with the two coupling sleeves 8 with respect to the cores 2, 3 and the housing 1.
  • the cores 2, 3 each have an inserted into the closing channel 5 end of the key 6 encompassing shell 10 and have on their the cam 7 facing end face each having a bottom 11.
  • the bottom 11 covers the center of the end face of the respective core 2, 3rd and thus the respective coupling sleeve. 8
  • FIG. 1 is an engagement surface 13 of the key 6 with the coupling sleeve 8 shown hatched.
  • the opening 12th is arranged in alignment with a form-fitting recess 14 of the coupling sleeve 8.
  • the cores 2, 3 on their side facing the cam 7 end face a circumferential groove 15 into which the coupling sleeve 8 penetrates with the form-fitting recess 14.
  • the coupling sleeve 8 encloses the central region of the core 2, 3.
  • the opening 12 and the form-fitting recess 14 have approximately the same width as the closing channel 5.
  • FIG. 3 shows for clarity one of the cores 2 with one of the coupling sleeves 8 in a partial section. It can be seen that the bottom 11 is formed as connected to the core 2 plug. Radially within the groove 15, the core 2, 3 has a cross-sectionally U-shaped central web 17 with the opening 12. In an alternative, not shown embodiment, the central web 17 may also be formed by a plurality of pins arranged in a circle for limiting the opening 12.
  • FIG. 4a shows in a sectional view through one of the cores 2 and the coupling sleeve 8 FIG. 1 in that the coupling sleeve 8 has a smaller wall thickness than the distance between two profile ribs 16 of the key 6.
  • the closing rib 5 points out of the profile ribs 16 of the key 6 FIG. 1 correspondingly shaped profile grooves.
  • FIG. 4b shows in a sectional view through the arrangement FIG. 4a in that the engagement surface 13 of the coupling sleeve 8 with the key 6 is made particularly long.
  • FIG. 5a shows in a sectional view a further embodiment of the coupling sleeve 8 and the core 2, in which the coupling sleeve 8 is guided to a radially outer profile rib 16.
  • FIG. 5b shows in a sectional view along the line Vb - Vb that the key 6 has a short engagement surface 13 with the coupling sleeve 8.
  • FIGS. 5a and 5b extends the engagement surface 13 of the coupling sleeve 8 according to the embodiment of the Figures 6a and 6b with the key 6 via two profile ribs 16.
  • the coupling sleeve 8 is designed eccentrically, so that a central web 17 of the core 2 enclosing inner contour is offset from the outer contour of the coupling sleeve 8. This ensures a particularly large contact surface of the coupling sleeve 8 on the key 6.
  • FIGS. 7a and 7b The embodiment according to the FIGS. 7a and 7b is different from the one from the Figures 6a and 6b only in that the positive engagement recess 14 widens conically radially outward.
