Definitions

  • the invention relates to a lock cylinder, in particular profile cylinder, preferably for a door lock, wherein the lock cylinder is secured against manipulation using the so-called impact technique.
  • Locking cylinders have a housing in which a receiving space for receiving a core is formed.
  • the core is rotatably mounted in the receiving space of the housing.
  • In the core there are a plurality of first receiving bores, which in particular extend radially, starting from the key-receiving lock channel to the outside of the core.
  • In the housing also a plurality of second receiving bores are formed, which are open to the receiving space and also extend radially to the core.
  • the first and second mounting holes are aligned in pairs. In the first receiving holes of the core are closing or core pins, while in the second mounting holes of the housing locking or housing pins are located, which are usually pressed by spring force against the core pins.
  • the core pins are radially disengaged in accordance with the configuration of the key blade.
  • the lock cylinder is opened when the mating surfaces of all pairs of core and housing pins are aligned with the outer surface of the core.
  • Lock cylinder of the aforementioned type are, for example DE-C-199 34 883 .
  • Lock cylinders are generally considered burglar resistant, but unfortunately are not always protected from all types of manipulation. It is particularly disadvantageous if it is not possible to recognize on a lock cylinder not opened with the proper key that it has been opened by manipulation in an inadmissible manner. In addition to the inconvenience associated with a theft inconvenience, the injured party then still has the problem of being unable to prove that the lock cylinder has been opened by unauthorized manipulation.
  • a lock cylinder in which one of the housing pins is formed in two parts and has a sleeve-shaped first pin part and a second pin part received by this with mushroom head.
  • the sleeve bears against the housing pin spring, while the mushroom head end faces the core of the lock cylinder.
  • An object of the invention is to provide a lock cylinder, in particular profile cylinder, against manipulation attempts after the impact technique or other manipulation attempts, with which an alignment of all core and housing pins with the outer surface of the core or inner surface of the housing-receiving space for the core can be achieved is protected.
  • At least one of the housing pins is thus formed in two parts, wherein a spring acts between the two pin parts, which biases the one pin part in the direction of the core.
  • this at least one two-part housing pin comprises a sleeve, the bottom of which bears against the first spring and whose open end faces the core.
  • the sleeve serves to guide the second pin part and for receiving the spring and the second pin part.
  • the lock cylinder according to the invention comprises a plurality of housing pins and a plurality of core pins, wherein at least one, preferably a plurality of housing pins, are formed in two parts.
  • the two-part design of at least one of the housing pins has the advantage that it takes place at a bias of the core, as in today's usual manipulation attempts by the impact technique, by electro-picking devices or by the individual Hineinbe ashamed the housing pins, even then Relief of the core comes when the separation plane or the gap between the two housing pin parts is equal to the level of separation of the housing and core. But then the core can not turn further. Since it is not clear to the manipulator that the relief of the prestressed core does not occur due to the completely inserted housing pin, it can not counteract this type of "core relief" either. Thus, there is effective protection against manipulation by utilizing dynamic processes in the housing and core receiving bores.
  • the spring coupling of the at least one two-part housing pin is also advantageous if the extremely unlikely event should occur that the two pin parts are moved apart and a plane between the two apart moving pin parts coincides with the separation plane of the housing and core. Then namely the core can twist or this can not be prevented by the two-part housing pin.
  • This blocking mechanism is basically in DE-C-199 34 883 described, but with the difference that there is the wire in an additional housing bore (without housing pin), while according to the invention described herein, the wire in a housing pin hole, ie a housing bore with housing pin, an additional hole for the wire therefore not required is.
  • the same wedging mechanism is also provided when a part of the two-piece housing pin is sheared due to a strong bias of the core in the housing.
  • Shearing off the two-piece housing pin could be prevented by making the parts or at least part of this housing pin of an extremely resistant material, e.g. Ceramics, consist / consist.
  • an extremely resistant material e.g. Ceramics, consist / consist.
  • the other pin part received by the sleeve has a shank and a widened end.
  • the one pin part is provided with a shank received by the sleeve and a widened end arranged outside the sleeve.
  • the shaft has a greater axial length than the sleeve.
  • a two-part housing pin is opposed to a one-piece core pin.
  • the profile cylinder 10 has a housing 12 and a cylinder core 14, which is rotatably arranged in a receiving space 16 of the housing 12.
  • the cylinder core 14 is provided with an off-center axial locking channel 18, in which the key 20 can be inserted.
  • In the cylinder core 14 are a plurality of rows arranged core pins (in the embodiment, five pins in a row), which are in (first) receiving holes 24 of the cylinder core 14. These receiving bores 24 extend radially through the cylinder core 14 between the closing channel 18 and the outer side 26 of the cylinder core 14.
  • the housing 12 In the housing 12 are a plurality of second mounting holes 28, the number and arrangement of the number and arrangement of the first mounting holes 24 are the same.
  • the second receiving bores 28 extend radially relative to the receiving space 16 of the housing 12 and are in the rotational position of the cylinder core 14 according to FIGS FIGS. 1 to 3 arranged in alignment with the first receiving holes 24.
  • housing pins 32 In the first mounting holes 24 are the differently long core pins 30, while housed in the second receiving holes 28 housing pins 32 which are biased by helical compression springs 33 in the direction of the core pins 30.
  • the helical compression springs 33 press via the housing pins 32, the core pins 30 against the disposed in the closing channel 18 ends of the first mounting holes 24.
  • the housing pins 32 extend both within the first and the second mounting holes 24,28, so that a rotation of the cylinder core 14 is prevented by the housing pins 32 ( Fig. 1 ).
  • the core pins 30 When inserted key 20, the core pins 30 are moved radially outwardly, by the key 20.
  • the tuning of the width of the key 20 is so matched to the length of the core pins 30 that they are aligned with inserted key 20 with the outside 26 of the cylinder core 14 , In this situation, the housing pins 32 are completely pressed into the second receiving holes 28, so that now the cylinder core 14 can be rotated ( Fig. 2 ).
  • At least one of the housing pins 32 is formed in two parts.
  • This two-part housing pin 32 has a first pin part 34 and a second pin part 36.
  • a spring 38 acts, which, with appropriate freedom of movement at least to one side of this housing pin 32, for a movement apart of both pin parts provides (helical compression spring).
  • the first pin part 34 is formed in the manner of a sleeve 40, at the bottom of which the housing pin 32 biasing spring of the receiving bore 28 abuts.
  • the open end of the sleeve-shaped first pin part 34 faces the core 14.
  • In the sleeve 40 is at least partially the second pin member 36 and the spring 38.
  • the second pin member 36 itself has a shaft 42 and a widened end 44, wherein the shaft 42 is received by the sleeve 40.
  • the shaft 42 has an axial extension which may be greater or smaller than the axial extent of the sleeve 40.
  • the housing pin 32 moves into the receiving bore 28 of the housing 12.
  • the second pin member 36 is opposite to the direction of movement of the housing pin 32 moves back to the core 14 where it dips into the receiving bore 24. This is done directly and immediately.
  • the pin member 36 thus executes each of the pin member 34 opposite movement, so that it is never ensured that the pin member 36 is aligned with the outside of the core 14.
  • FIG. 4 This situation is in Fig. 4 shown.
  • the separation plane or the separation region between the two pin parts 34 and 36 is now aligned with the separation plane between the housing 12 and the core 14. Since the core 14 is biased, it can now be rotated by the radial clearance between the two pin parts 34 and 36 , but at the same time the movement of the second pin member 36 is prevented in the housing-receiving bore 28, since the second pin member 36 abuts with its widened end 44 against the housing 12.
  • the relief of the housing pin 32 is as if the contact plane between the housing pin 32 and the core pin 30 in height of the separation plane between the housing 12 and core 14 is located.
