Definitions

  • the invention relates to a key for locking a cylinder lock with at least one first surface and at least one second surface and scanning positions provided along the longitudinal extent, with at least one coding being provided on the first surface and at least one further coding being provided on the second surface, and with the codings control points provided at the scanning positions transverse to the longitudinal extent of the key and arranged at specific control heights.
  • the invention also relates to a cylinder lock for such a key and a system made up of such a cylinder lock and such a key.
  • Reversible keys are keys whose shank has profiles, guide grooves, recessed bores, elevations and/or notches arranged in the same way on both sides.
  • a reversible key has the same features when rotated around its longitudinal axis and can therefore - regardless of which side of the key points upwards - be inserted rotated into the keyway of the associated lock cylinder, which is not possible with a normal key notched on one side.
  • the codes on reversible keys are identical on both sides, the codes on each side are usually queried alternately in the lock in order to reduce the number of scanning elements.
  • the term "identical coding” means that the coding on the surfaces under consideration is the same when the key is rotated about its longitudinal axis.
  • An object of the invention is to eliminate these and other problems of generic keys and locks.
  • a new key and a new lock are to be implemented that offer sufficient possible combinations and are difficult to copy.
  • the problem of copying reversible keys is to be solved by the invention.
  • a possibility should be created to be able to block several different reversible key locking systems with the same key.
  • the restriction described above with regard to the coding on the side of the key tip should be eliminated.
  • the possible variations on the key are to be increased and greater blocking security is to be ensured.
  • the same effects should also be achieved with regard to the new design of the castle.
  • the problem is to be solved that existing keys can block new locking systems if both surfaces of the key are not queried in these new locking systems.
  • a key having the features of claim 1 having the features of claim 1 .
  • the number of possible combinations of the key is increased by the fact that, according to the invention, at least one control point on both surfaces has a different dimension, preferably a larger diameter, at at least one scanning position than a control point at another scanning position.
  • At least one scanning position on the key the codings of the two surfaces are different from a locking point of view, and at least one scanning position the codings of the two surfaces are identical from a locking point of view.
  • This embodiment of the invention solves several problems. First of all, there is the advantage that it is much more difficult for unauthorized persons to copy the key, since the coding on the two surfaces of the key is different.
  • the solution according to the invention makes it possible to use a key to lock one or more locking cylinders in a locking system and, when the key is rotated about its longitudinal axis by 90° to 180°, to lock one or more locking cylinders in another locking system.
  • a key that has the same coding on both sides does not have blocking authorization. However, it can also be provided that a key which has the same coding on both sides has blocking authorization.
  • An advantage of the solution according to the invention is that the feature for the authorization to lock multiple lock cylinders does not have to be included in the lock cylinders of the locking systems, but is implemented with at least two or more features on different surfaces of the key itself. As a result, a key can be designed which has a superior function in two different reversible key locking systems but does not have the reversible key function itself.
  • This can, for example, be a higher-level key for authorized persons, such as the fire brigade, night watchman, home help or the like.
  • Another advantage of the solution according to the invention is that when the key is designed with curve coding, the different characteristics of the curves on the two sides of the key mean that the middle tumbler on the tip of the key can now also be used, since it is not on both sides in the form of a groove must be milled out.
  • control points and/or other codings at other points of the key have essentially straight, angled, circular or curved, horizontal or vertical grooves, grooves, millings, indentations or elevations, control surfaces, control tracks, troughs, drilling troughs with identical or different diameters and/or depths, mounted balls, circular or elliptical segment recesses, elevations or depressions in the shape of spherical segments, magnetic coding, electronic coding and/or combinations of these elements.
  • the surfaces are the flat sides of the key. According to the invention, it can also be provided that the surfaces are the narrow sides of the key. According to the invention it can be provided that the first surface is a narrow side of the key and the second surface is a flat side of the key. The second surface can enclose any desired angle, in particular approximately 90° or approximately 180°, with the first surface of the key.
  • control points are connected to one another by control grooves.
  • At least six scanning positions A-F can be provided in the longitudinal direction of the key and at least six control heights a-f have been provided in the transverse direction of the key.
  • At least three control grooves are provided, of which at least one is designed as a deep control groove with deep control points and the remaining as shallow control grooves with shallow control points, the deep control grooves having a greater groove depth than the shallow control grooves and the shallow Control grooves essentially parallel to each other.
  • At least three, preferably five, control heights can be provided for at least one control groove, preferably for the shallow control grooves.
  • the codings starting from a key tip of the key in the direction of a key bow of the key, are initially identical on both surfaces and are different from a certain scanning position, preferably continuously different.
  • the deep control groove or the shallow control grooves extend only up to a certain scanning position and the other control grooves extend beyond that.
  • control point with a different dimension is arranged at the first scanning position, starting from the tip of the key in the direction of the bow of the key.
  • control point with a different dimension has a larger diameter than the control points at the other scanning positions.
  • control point with a different dimension is part of the deep control grooves.
  • control point with a different dimension can have a diameter that is about 10% to about 40% larger than the diameter of the other control points.
  • the deep control grooves are arranged between the shallow control grooves on the key tip and merge into them, so that no separating web of material remains between the deep control grooves and the shallow control grooves on the key tip.
  • two grooves of different depth and width can be provided on the key tip, which are designed to distribute three different control elements of the cylinder lock to two shallow and one deep control groove, the deep control groove being tapered from the key tip in the direction of the key bow .
  • a preferably funnel-shaped inlet area can thus be formed at the key tip.
  • the deep control groove starting from the tip of the key to the control point, is designed with a larger diameter as a deep control groove with a larger diameter.
  • the diameter of the deep control groove can essentially correspond to the diameter of the control point with a larger diameter.
  • the invention also extends to a cylinder lock for a key according to the invention, comprising a key channel with at least two sides with scanning positions provided along the longitudinal extent, at least one control element with control elements for engaging in at least one coding on at least one surface of the key being provided at each scanning position , wherein at least one blocking element is provided, which can be brought into the release position for actuating the lock when the control element is in the appropriate position.
  • control elements have a different dimension, namely a greater width, at at least one scanning position than at the other scanning positions. This results in the technical effect that the keys described above, which have a control point with different dimensions, can be queried.
  • These control members with different dimensions can preferably be arranged on only one side of the key channel.
  • control elements for querying different codings on two surfaces of the key are provided, and at least at a second scanning position on two sides of the key channel control elements for querying identical coding on two surfaces of the key are provided.
  • control elements include first control elements for engaging in deep control grooves and second control elements for engaging in shallow control grooves.
  • control elements for controlling the blocking elements have engagement means, in particular one or more interrogation grooves, which interact with the blocking element in one or more positions of the control element such that it can be brought into the release position for actuating the lock.
  • those control elements with different dimensions are arranged at the last scanning position, starting from a core head of the cylinder lock, and are designed for scanning control points with a larger diameter, the control points with a larger diameter each being part of a deep control groove with a larger diameter, which extends into the deep Pass control grooves.
  • the control elements with different dimensions correspond to the control points with different dimensions of a key according to the invention.
  • the invention also extends to a system of at least two locks or groups of locks according to the invention and at least one associated key according to the invention, with at least one first lock or a first group of locks at least only the first coding on the first surface at at least one specific scanning position, and at least a second lock or a second group of locks at least only the second code on the second surface of the key queries at this scanning position, so that the key locks the first lock or the first group of locks in a first position and locks the second lock or the second group of locks in a second position .
