Definitions

  • Locking device with a lock and with a key
  • the invention is directed to a locking device specified in the preamble of claim 1.
  • Art on a surface side of the edge profile extends a profiled paragraph in the key longitudinal direction, which generates a set of sampling points for a standard coding on the key through its profile profile.
  • At least individual tumblers are provided with a counter paragraph, which is supported by a key inserted at a defined point of this paragraph.
  • These counterparts act as backscores to the standard encoding of the key, which is why they should be referred to as standard tumblers.
  • the group of all standard tumblers arranged in a cylinder core generates with their counterparts the complementary standard counter coding to the associated key.
  • Such a closing device is known from DE 199 44 070 C2.
  • the coding of the key consists of a key in the longitudinal direction extending coding groove.
  • the associated tumblers have a projection which engages inserted key in a certain cross-section of the coding groove.
  • the variety of variations for the coding of the key and the counter coding in the associated package of tumblers can be increased at a given level of increments between successive code positions only by increasing the key length or the key width. With a larger key length, a larger number of tumblers can be arranged in the cylinder core. With a larger width of the key can be to increase the number of increments to code the key.
  • Both measures have the disadvantage that increases the overall height or length of the entire locking device. An enlargement of the dimensions of the closing device is undesirable.
  • the known locking device has the disadvantage that it can break up relatively easily with burglary tools.
  • a closing device of another type where the key has a polygonal shaft cross-section. At isolated locations, which are circumferentially and axially separated from each other, there are notches of varying depth at the edges which serve to code tumbler pins. In the region of a cross section of the key shaft, only the local notch assigned, oriented in a certain direction pin tumbler can attack, which can not be replaced by other pin tumblers, which are in the opposite direction and spring loaded. At the end of the shaft, although bevels are arranged on the side surfaces lying between the edges, these serve only for lifting the tumbler pins when the key is inserted. An encoding function does not apply to these ramps.
  • the invention has for its object to develop a space-saving locking device referred to in the preamble of claim 1 species, which is characterized by a high resistance to breakage. This is inventively achieved by the measures listed in claim 1, which have the following special significance.
  • At least one corner region of the edge profile of the key is used to produce by oblique cuts an additional bevel coding in the key.
  • Unauthorized persons who want to break the lock cylinder do not know whether in a particular section of the key, the usual standard coding or in the claim mentioned beveled coding is present and in which direction this bevel coding acts.
  • a standard tumbler can be arranged at a specific sampling point, which then uses the standard coding of the key cooperates, or be placed a bevel lock, which is supported on the bevel coding. This can already increase the variety of variations of the locking device according to the invention. Considering.
  • the standard coding and the beveled coding at the different corner regions of the key run side by side in the key longitudinal direction, so that the aforementioned multiple sampling points in a cross section of the key can optionally be used.
  • the scanning direction of the associated bevel edge tumbler can be embodied differently at the scanning point of a specific beveled edge coding.
  • the scanning direction may be positioned at any angle, e.g. parallel to the scanning direction of the standard tumbler, vertical or in any inclination.
  • FIG. 1a is a perspective view of a first embodiment of the key according to the invention
  • Fig. I b shows a cross section through the shaft of the key of Fig. I a in
  • FIG. 2a + 2b two perspective views of a second embodiment of the key according to the invention in two different directions.
  • Fig. 2c is an analogous to Fig. 2a perspective view of

  • the known locking device shown in Fig. 3 and 4 shows the structure which can be found in an analogous manner in the closing device according to the invention. However, it differs from this in essential points, which will be explained in detail. First, it depends on the basic structure of such a closure device, which also applies to the invention.

At the two opposite narrow sides of the rectangular profile 25. 1 is a lateral distance 17 between the two adjacent beveled codings 27.1, 27.2 on the one hand and 27.3 and 27.4 on the other. These corner strips 21 to 24, which extend in the key longitudinal direction, generate four beveled codings, which are formed case by case different from each other.

If one looks at the possibility of variation of different increments of the standard coding 53 and the variation of the incision depths of the beveled edge coding 27.1 to 27.4 of FIG.
  • tumblers can engage in one and the same place in the cross-section of the key 20.2, namely 13, 14.1. 14.12, 14.13 or 14. 14. These tumblers are located either in one of the chambers 19 of the cylinder core 12 which is located at this point of the inserted key 20.2.

Abstract

L'invention concerne un dispositif de fermeture constitué d'un barillet et d'une clé (20.2). Le barillet est pourvu d'un noyau de barillet, intégrant des gâchettes (13, 14.1) et monté de manière rotative dans un corps de barillet. Un codage standard de la clé (20.2) s'obtient par l'intermédiaire d'un épaulement à profil longitudinal (28) formé sur au moins une face plate du profil à pans de la clé (20.2), épaulement auquel est associé un épaulement correspondant (30) sur la gâchette (13). Outre ce codage standard (28, 30), la clé présente au moins un codage par biseaux (27.1, 27.4) dans une zone d'angle du profil à pans. Ce codage par biseaux est constitué d'évidements sous forme de coupes diagonales dans les zones d'angle associées du profil à pans, dont les points de palpage correspondants (47.1) sont formés dans la gâchette associée (14.1). Ainsi, le codage standard ou bien un des codages par biseaux peuvent être utilisés de manière facultative dans une partie de la tige de la clé, ce qui augmente sensiblement le nombre de variantes du dispositif de fermeture à faible encombrement selon l'invention.
