Definitions

  • the invention relates to a key for actuating a lock cylinder, with a key bow and a key shank extending from the key bow according to the preamble of claim 1.
  • the invention also relates to a locking system with such a key and an associated lock cylinder according to the independent claim.
  • Keys and locking systems of the type mentioned are known from the prior art, for example FR 2 492 872 A1 .
  • a key is described, in the key shank a channel is formed, which extends perpendicular to the median longitudinal plane of the key shank and in which an actuating element is movably mounted.
  • the actuating element can be displaced along the channel via a button element arranged in the cylinder core, so that a conventional tumbler arranged in a waisted area of the lock cylinder can be actuated.
  • Such a design makes it difficult to use simple copying methods.
  • it is problematic that such key profiles can also be identified and reproduced with copying processes that are now available, e.g. from 3D scanners and 3D printers. This affects security.
  • the invention is based on the object of enabling comparatively safe and reliable operation in a key or a locking system with simple structural means.
  • the key used to actuate a lock cylinder has a key bow and a key shank extending away from the key bow.
  • a channel extending through the key shank along a channel axis is formed in the key shank.
  • the channel is designed as a stepped bore, in particular as a precision stepped bore, with the axis of the channel forming an angle of less than 90° with the central longitudinal plane of the key shank.
  • In the canal is a along the canal displaceable actuating pin arranged for actuating a lateral tumbler of the lock cylinder.
  • the proposed configuration of the channel forms a comparatively compact undercut which, in addition to the actuating pin displaceable in the channel, can only be reconstructed with great effort, if at all, using modern copying methods.
  • the stability of the key shank is only negligibly affected by the stepped bore. This favors security.
  • the channel for the confirmation pin can be arranged in the half of the key shank facing away from the bow of the key (front half of the key shank), in particular in the front third of the key shank.
  • a (lateral) tumbler corresponding to the actuating pin can be arranged at or near the inner end of the key channel of an associated lock cylinder. This makes manipulation more difficult.
  • the channel for the confirmation pin can be adapted to the shape and/or the dimensions of the confirmation pin, so that the actuating pin can be moved along the channel.
  • the key shank extends in particular along an axial direction away from the key bow.
  • the key has narrow sides that run along are oriented to the thickness/strength of the key.
  • the key for actuating a lock cylinder can in particular be a profile cylinder key.
  • the associated lock cylinder can be designed in particular as a profile cylinder. "Related" means that a key is matingly insertable into a lock cylinder such that the lock cylinder can be operated by the key.
  • the profile cylinder key can be designed as a bit key ("conventional profile cylinder key").
  • a bit key can only be inserted into the key channel of an associated lock cylinder in one orientation.
  • the channel can be the only channel extending through the key shank and the actuating pin can be the only confirmation pin arranged in the key shank. This contributes to a structurally simple design with as few components as possible.
  • the key shank at least in sections, be profiled such that a Indentation on a key shank side is opposite a bulge on the other key shank side.
  • This contributes to a comparatively stable design of the key shank, since material weaknesses caused by an indentation on one side of the key shank are largely compensated for by bulges on the other side of the key shank.
  • the key shank can expediently have an asymmetrical cross section. This allows a special key geometry to be created. In addition, the rigidity of the key shank can thus be increased.
  • the key shank can be dimensioned in such a way that six profile incisions can be formed in each of the key shank sides.
  • a total of twelve profile incisions can be formed on the key shank, preferably six on each side of the key shank.
  • a comparatively large variety of key secrets can be provided in this way.
  • a longitudinal groove can be formed at least on one side of the key shank, which extends (axially) from the channel to the free end of the key shank (key shank tip). This enables the key to be easily inserted into a key channel, particularly when the stop element on the cylinder side is stationary in relation to the key channel or the cylinder core of the lock cylinder and/or protrudes into the key channel.
  • the longitudinal groove can then serve as access for the projecting stop element on the cylinder side.
  • the channel can be open and reduced in cross-section at a first channel end, with the actuating pin having an actuating section at a first pin end which protrudes at least partially from the key shank when the actuating pin is in contact with the first channel end.
  • the actuating pin is thus secured at the first end of the channel against falling out of the channel.
  • the actuation section of the actuation pin can actuate a lateral tumbler, in particular a locking pin (core pin) of the lateral tumbler.
  • the channel at its first channel end and the actuating pin at its first pin end can be designed to be at least partially, preferably completely, complementary to one another.
  • the inner contour of the channel and the outer contour of the actuating pin correspond to each other.
  • the actuating pin can lie against the first channel end of the channel over a large area.
  • the cross sections of the channel and the actuating pin at the first end change in particular in the same way.
  • the channel can have a first channel section with a first cross section, in particular a first inner diameter, a second channel section with a second cross section, in particular a second inner diameter, and a third channel section with a third cross section, in particular a third inner diameter.
  • first cross section in particular a first inner diameter
  • second channel section with a second cross section
  • third cross section in particular a third inner diameter.
  • a connecting section can expediently be arranged between the first channel section and the second channel section, in which the channel cross section increases continuously, preferably conically, from the first channel section to the second channel section. This creates a comparatively large contact surface for the confirmation pin.
  • a shoulder can preferably be formed between the second channel section and the third channel section, in in which the channel cross-section increases from the second channel section to the third channel section. Precise guidance for the actuating pin can thus be achieved through the second channel section, with the shoulder creating a comparatively large contact surface for the actuating pin.
  • the channel can be designed to be open at a second channel end and have a reduced cross section.
  • a safeguard against falling out of the actuating pin is created.
  • the edge of the channel at the second end of the channel can be shaped, for example compressed, in particular after the actuating pin has been inserted into the channel, such that the actuating pin is secured against falling out.
  • the locking system has a key with one or more of the above aspects and an associated lock cylinder.
  • the lock cylinder has a lateral tumbler for actuation by the displaceable confirmation pin of the key and a stop element on or in its keyway.
  • the actuating pin comes into contact with the stop element and is thus displaced in the channel of the key shank, which in turn moves the lateral guard locking to the release position.
  • the lateral tumbler can be arranged in the diameter area of the cylinder housing. This creates a lateral tumbler with simple design means.
  • the stop element can be designed as a pin arranged orthogonally to the central longitudinal plane of the key channel in the cylinder core.
  • the stop element or the pin is in particular fixedly arranged in the cylinder core (pin cannot be displaced in the cylinder core).
  • the free end (front end) of the pin can protrude into the keyway.
  • the longitudinal groove formed in the key shank can correspond to the free end of the pin in such a way that the key shank can be inserted into the key channel.
  • the lateral tumbler can expediently have a housing pin and a locking pin, with the actuating pin acting on the housing pin via the locking pin when the key shank is inserted into the key channel.
  • the locking pin can be actuated via the actuating pin in such a way that the parting plane of The housing pin and locking pin are located on the outer surface of the cylinder core, ie on the interface between the cylinder core and the lock cylinder housing.
  • the housing pin can be arranged displaceably in the diameter area of the housing and/or be spring-loaded by means of a spring, in particular a compression spring.
  • the locking pin can be slidably arranged in the cylinder core and/or not be spring-loaded.
  • a press-in stopper can be provided, which closes an opening for lateral locking in the diameter area of the housing.
  • the spring in particular a compression spring, can be arranged between the press-in plug and the housing pin.
  • the central longitudinal axis of the locking pin and the central longitudinal axis of the actuating pin can preferably enclose an angle with one another.
  • the central longitudinal axis of the actuating pin and the central longitudinal axis of the stop element (pin) can also form an angle with one another. This contributes to a comparatively compact arrangement of the components.
  • the actuating pin acts as a deflection pin, which deflects a force applied to the actuating pin by the stop element (pin) onto the locking pin.
  • the central longitudinal axis of the housing pin and the central longitudinal axis of the locking pin enclose an angle with one another. This also favors a compact arrangement of the components.
