Definitions

  • the invention relates to a locking cylinder with a tumbler, with a cylinder housing, the one circular cylindrical, running in the longitudinal axis direction Has bore in which one in a orthogonal to its longitudinal axis Cross section of a cylindrical cylindrical core with a key channel a flat key is rotatably arranged, with at least two pairs of Tumbler pins, each made by a compression spring towards the core loaded housing pin and each arranged coaxially thereto Core pin exist, the pairs of core and body pins from the flat key in the unlocked position on one between the outer surface of the core and the bore of the cylinder housing receiving the core provided interface in unlocked position (open position) are controllable, the flat key variable key recesses to control the housing pin and core pin has spring-loaded tumblers and at least two core pins under are arranged at an acute angle to the center line of the flat key.
  • Lock cylinders of the aforementioned type are known from DE 37 36 129 C2 and of EP 0 313 864 B1 with the same content. Both in these publications as well as other locking systems with multiple tumbler series are these arranged horizontally to the core longitudinal axis, that is to the core center, or are parallel at right angles to it and also cut the core longitudinal axis.
  • Lock cylinders of this type are also known from the following publications:
  • locking cylinders according to DE 37 36 129 C2 and EP 0 313 864 B1 already have a high security standard.
  • the invention has for its object a locking cylinder of the prerequisites Type with the highest security against locking and extraordinary scanning security embody.
  • the core pin ends become at least partially the core pin ends at the end in a manner which complicates scanning in all of the aforementioned Solutions secured against scanning.
  • These wall parts can accordingly the penetration curves of the holes for the core pins on the one hand in the key channel on the other hand be formed and accordingly the core pin ends wholly or partially enclose sleeve-like, so that after peeling scanning the flat key is impossible.
  • At least two core pins with associated housing pins which are loaded by compression springs against the core pins are offset by 180 ° and arranged with their longitudinal axes running parallel to one another.
  • a flat key which can be designed either as a reversible key or as a longitudinal rib profile flat key
  • the core pins can be controlled in opposite directions against the springs of the housing pins in the open position.
  • the longitudinal axis of at least one of the core pins, which runs coaxially to the longitudinal axis of the associated housing pin intersects a center line which runs through the center of the key channel and through the core longitudinal axis, namely outside the core longitudinal axis at an acute angle. If necessary, both longitudinal axes of the core pins can intersect this center line outside the core longitudinal axis.
  • the longitudinal axis of at least one core pin intersects the longitudinal axis of the core, while the longitudinal axis of at least one other core intersects this center line eccentrically, that is, outside the longitudinal axis.
  • the solution according to independent claim 3 differs in that the two longitudinal axes of at least two core pins intersect said center line at a distance from the center of the key channel.
  • the center of this key channel is thus eccentric to the longitudinal axis of the rotatable core.
  • the distances at which the longitudinal axes of the core pins intersect the line running through the longitudinal axis of the core and through the center of the key channel are the same.
  • At least one further core pin with a spring-loaded housing pin is arranged in the angular range to core pins arranged on different sides of the core.
  • several such core pins with associated spring-loaded housing pins can also be additionally distributed over the circumference of the cylinder housing. This further increases the security of the lock considerably.
  • a plurality of rows of core pins and associated housing pins are arranged next to and / or one behind the other in the longitudinal axis direction of the core, which further contributes to increasing the security against locking.
  • Claim 7 describes an embodiment in which core pins, each of which are specially designed in pairs, with associated housing pins are alternately arranged on different sides of the core and distributed over its circumference.
  • a preferred embodiment describes claim 8 , which at the same time refers back to one of the independent claims. It follows that the core is provided with a recess through which such core pins, whose longitudinal axis no longer intersects the core longitudinal axis in the center, are gradually controlled from the eccentric position during the opening movement by means of a suitable flat key into the parting plane between the core and the bore of the cylinder housing are, while this parting plane with lock cylinders belonging to the prior art only lie at the cylindrical transition from the inner bore of the lock housing for receiving the rotating core and its outer surface.
  • This recess or shape for the "eccentrically" arranged core pins is based, on the one hand, on a gentle closing process for the core pins, since the outside of this recess, which forms a second parting plane, merges smoothly into the outer cylindrical outer surface of the otherwise circular core.
  • a small area or flat curve will be assumed which gradually rises to the outer circumference of the core and which smoothly merges into the outer surface of the core through a curved curve.
  • claim 9 describes a preferred solution.
  • the core pin rows are connected to associated housing pins by a continuous surface on this side of the core, which form the respective curved recess.
  • the individual recesses of different core pins with rows of housing pins can also be separated from one another by webs. These webs form sections of the outer surface of the rotating core on their outside.
  • the core pins are rounded or rounded at their end section facing the flat key. This enables a smooth, jerk-free closing process with little effort.
  • the solution according to claim 13 also contributes to this.
  • the flat key is provided as a longitudinal rib profile flat key with undercuts and / or profiles.
  • the profiles can preferably be provided on one of the narrow sides of the key, but also on both narrow sides and / or on the broad sides of the longitudinal rib profile flat key. This depends on the number of core pins arranged in the core and the design of the key channel.
  • Claim 15 describes a further particularly advantageous embodiment.
  • the flat key is designed as a reversible key.
  • the reversible key is preferably provided at least on its opposite broad sides with corresponding recesses, bores or recesses through which the core pins are to be controlled.
  • Claim 16 describes a further advantageous embodiment of the invention.
  • Claim 17 describes an advantageous embodiment of the invention.
  • reference numeral 1 denotes a cylinder housing, which has a circular cylindrical bore 2 running in the longitudinal axis direction, in which a cross-section guided orthogonally to its longitudinal axis circular core 3 is arranged with a key channel 4.
  • a flat key 5 can be inserted, the corresponding the cross-sectional shape of the key channel 4 is designed.
  • the flat key 5 can be used as a so-called longitudinal rib profile flat key or as Reversible key be formed and corresponding incisions and / or Have blind holes. These incisions or the like of the flat key 5 can be seen particularly clearly from FIG. 6.
  • the center lines 6 of the flat key 5 are coaxial arranged to the center line 7 of the key channel 4, so coincide.
  • the Center line 7 of the key channel 4 runs through the center of rotation of the Kerns 3 and thus through the core longitudinal axis 8, this intersects orthogonally.
  • A also runs to the center line 7 of the key channel 4
  • the transverse center line running orthogonal to the center line 6 of the flat key 5 is designated by the reference number 10 (FIG. 6).
  • This cross center line 10 falls with a transverse center line when the flat key 5 is inserted into the key channel 4 11 together, which are orthogonal to the center line 7 of the key channel 4 runs.
  • the transverse center line 11 is designated with the center line of the key channel 4 the center of the key channel 4 through which the longitudinal center axis of the key channel 4, which is directed parallel to the core longitudinal axis 8 is. As you can see, this is the center of the key channel 4 arranged at a distance A from the center of the core 3 (Fig. 4 and 5).
  • the core 3 is either in the direction X or in To turn direction Y in the bore 2 of the cylinder housing 1 (Fig. 7 to 11).

  • curve 28 goes smoothly into the outer surface 14 over to enable a smooth closing process.
  • Out Fig. 7 shows the start of a closing movement.
  • the flat key 5 is inserted in the key channel 4 and the core 3 is around its Longitudinal axis 8 rotated in the direction of arrow X. It can be seen how the housing pin 20 with its end face slides along curve 28 until, according to FIG The lateral surface 14 of the core 3 occurs and slides further along here. From Fig. 9 is to recognize how the housing pin 20 with its head part 16 on the outer surface 14 of the core 3 slides along.
  • Fig. 10 shows the opposite direction of rotation of the core in the direction Y and sliding along the housing pin 20 on the curve 28 until the housing pin 20 in turn occurs on the outer surface 14 of the core 3 and on this slides along, which can be seen from FIG. 11.
  • the recess 27 and curve 28 thus become a second interface or so to speak Partition plane between the bore 2 of the cylinder housing 1 and the outer surface 14 of the core 3 formed so that the lock cylinder despite the eccentricity of the core pin 13 locked and unlocked with respect to the core longitudinal axis 8 can be.
  • At least one further core pin 29 can be located between the core pins 12 and 13 be provided, which can be designed and arranged as the Core pins 12 and 13.
  • This core pin 29 is also a housing pin 30 Compression spring 31 assigned, which turned away from the housing pin 30 Prestressed side supported against a rivet 32. The other compression springs too the housing pins are arranged preloaded.
