Definitions

  • the invention relates to a rotary lock cylinder for a security lock according to the preamble of claim 1.
  • Rotary lock cylinder of this type have long been known. They ensure high security. Like other security devices, they are subject to manipulation for unauthorized opening. Above all, simple and cheap locking cylinders often can not resist such manipulations.
  • One of these opening methods is known as "beating technique”. This opening method is low-profile and does not fundamentally damage the rotary-lock cylinder.
  • a blank which has a profiling which corresponds to that of the cylinder to be manipulated. Since the profiles of the cylinders are different, a corresponding set of blanks is needed. From this sentence, the matching blank is selected. The corresponding associated blank is inserted into the keyway and held in the desired direction of rotation of the rotor on the key handle with a suitable torque under pressure. With a striking tool is hit at the same time now on the handle. Through the blank, a pulse is exerted on the rotor pins in each case. According to the percussion principle, the core pins each transmit the impulse to the associated housing pin. The core pins remain standing here.
  • the housing pins are affected by the pulse received briefly moved against the retroactive force of the housing spring outward beyond the dividing line in the stator. Since the housing pins now no longer lock the rotor, this is free and can be rotated and thus the rotary lock cylinder can be opened. The blank can be removed and used for further manipulation.
  • the US 3,762,193 discloses a rotary lock cylinder outer, wherein the core pins have an inner part and an outer part, wherein the length of the outer part and the length of the associated housing pin together give a length which is greater than that of a bore, in which the housing pin is mounted.
  • the outer part would lock the rotor.
  • the WO 01/48340 A and the WO 97/07310 A show more rotary lock cylinder.
  • the invention has for its object to provide a rotary lock cylinder of the type mentioned, which reliably prevents this opening method and yet is reliable and can be produced cheaply.
  • the housing pins can continue to be moved outwards into the stator during a manipulation according to the above-mentioned principle.
  • the part of the core pin according to the preamble of claim 1 goes outside. This outer part takes over the blocking of the rotor due to the mentioned length ratios. Basically, it is sufficient if only such a tumbler has a core with an outer part and an inner part.
  • the two parts of the core pin have a recess or a corresponding projection on the contacting surfaces, which simplifies the assembly of the core pins.
  • the inner part of all two-piece core pins is the same length.
  • the inner part is preferably made of a hard material, such as hardened steel. Since all these parts can be made the same, their manufacture and the corresponding assembly is easy or inexpensive.
  • the outer part can be made of a comparatively soft metal, for example brass or nickel silver, since this part is less stressed than the inner part, which is engaged with the key. The effective length of the core pins is thus determined by the outer parts. These outer parts are correspondingly different in length.
  • the outer part of the core pin and also the inner part are preferably cylindrical and radially completely separable from each other.
  • the outer part of the core pin is punctured. This gives even greater security and prevents other opening methods. If such a rear-punched part is moved outwardly into the stator during the aforementioned manipulation, it can generally no longer be returned to the rotor when the rotor is tilted and remains in the blocking position. This is further enhanced if, according to a development of the invention, the bore in the stator is also punctured.
  • the housing pins are each mounted in slides.
  • the housing pins and the associated springs can then be filled outside the stator in the slide.
  • the core pins are inserted into the stepped holes of the rotor.
  • the mounting of the core pins is simplified if, according to the invention, the two parts of the core pin have a recess or a corresponding projection on the contacting surfaces.
  • a tumbler of the housing pin and the outer part of the core pin are connected by magnetic forces. This is done in particular by magnetic pins, which are firmly inserted into said parts. This magnetic connection ensures that the housing pin and the outer part are securely moved together and simultaneously outwards during said manipulation.
  • the housing pin and the inner part thus form a kind of package that dissolves in the said manipulation of the inner part of the core and migrates to the outside.
  • Rotary lock cylinder 1 is a simple rotary lock cylinder or a double-lock cylinder and has a stator S and a rotor R.
  • the stator S usually has three slides 3, of which only one is shown here. These slides 3 are inserted into a stator housing not shown here and each have a plurality of holes 4, each receiving a coil spring 5 and a housing pin 6 to 9. In the in FIG. 1 shown basic position, the housing pins 7, 8 and 9 exceed a dividing line T between the stator S and the rotor R and thereby lock the rotor R.
  • the stator S also has a sleeve 2, which close the holes 21 of the slide 3 to the outside and at which the springs 5 are supported. But the stator S can also be constructed as usual without slider 3 and sleeve 2.
  • the rotor R forms a keyway 24, in which the shank of the associated key for insertion of the tumblers Z1 to Z4 is to be inserted.
  • the key can be designed to be arbitrary, ie it can be in particular a reversible key with holes or a so-called spanner. In the FIG. 1 is the key channel 24 left open.
  • the rotor R has radial stepped holes 21 in which core pins K1 to K4 are mounted. These core pins K1 to K4 project as shown in the rest position in the keyway 24. By the springs 5, the core pins K1 to K4 are held in the rest position shown. Through the shoulders of the stepped holes 21, these positions are defined.
  • the core pins K1 to K4 each consist of an inner part 20 and one of the outer parts 10 to 13.
  • the inner parts 20 are as shown all the same length and the same design. They each have at a rear end a radially outwardly directed collar 27 which rests in the stepped bore on said shoulder.
  • the inner parts 20 are preferably made of a hard material, in particular hardened steel.
  • the back of the core pins 20 is each formed by a flat surface 28. At these flat and closed surfaces 28 lies in each case with a flat inner surface 15 (FIG. Fig. 2 ) of the outer parts 10 to 13.
  • These outer parts 10 to 13 are as shown different lengths. The effective length of the core pins K1 to K4 is thus determined by the different lengths of the outer parts 10 to 13.
  • the outer parts 10 to 13 each have an inner surface 29 and an outer surface 30.
  • the inner surfaces 29 are preferably also flat and lie flat against one of the surfaces 27 of an inner part 20.
  • the outer surfaces 30, however, are cambered and are each on an inner surface 15 of the housing pins 6 to 9 at.
  • the inner parts 20 and the outer parts 10 to 13 thus lie loosely and planar against each other. Radial parts 20 and 10 to 13 can be completely separated from each other.
  • the inner parts 20 are according to FIG. 1 each completely in the rotor R and thus have no blocking function in the rest position.
  • the outer parts 10 to 13 and the housing pins 6 to 9 are each provided with an inner radial bore 16 and 17, in which a magnetic pin 18 and 19 is firmly inserted.
  • the magnets 18 and 19 are each permanent magnets and fixed in the corresponding bore 16 and 17, respectively.
  • These magnetic pins 18 and 19 connect the outer parts 10 to 13 each with one of the housing pins 6 to 9.
  • the magnetic force acts only radially, so that upon rotation of the rotor R, the inner parts 10 to 13 of the housing pins 6 to 9 without Another can be separated.
  • the magnetic connection has the advantage that the inner parts 10 to 13 and the housing pins 6 to 9 are moved even more securely together in the exercise of said radial pulses and thus can not be separated from each other with said percussion principle.
  • the outer parts 10 to 12 are each backed behind. As a result, in each case an inner edge 31 and an outer edge 32 are formed, each projecting radially. Are the outer parts 10 to 12 according to FIG. 2 in the outer position, they are, as mentioned above, in each case moved inwards again by the springs 5. If, as mentioned above, a torque is exerted on the rotor R, the bores 21 in the rotor R and the bores 4 in the stator S are slightly offset relative to one another in the circumferential direction. The inner edge 32 can not exceed the dividing line T by this offset. This also applies in the reverse direction by the edge 31. The outer parts 10 to 12 are become. As a result, other manipulation attempts become ineffective.
  • the holes 4 are also punctured. It is on the EP 0 937 843 A referenced, showing which slide with recessed holes.
  • the housing pins can also be punctured, as per FIG. 1 in the housing pins 8 and 9 is the case.
  • the length L1 is the length of the outer parts 10 to 13.
  • the length L2 is the length of the housing pins 6 to 9. These lengths are different as shown.
  • the length L3 is the sum of the lengths L1 and L2. This length L3 is greater than the length L4, which is the length of the holes 21. It therefore applies L1 + L2> L4. Because of this relation it is ensured that in the position according to FIG. 2 always lock the outer parts 10 to 13. This also applies if according to FIG. 3 Also, the inner parts 20 are each offset outwards and thus do not protrude into the keyway 24.
  • FIGS. 4 and 5 show a tumbler Z1 'according to a variant.
  • the outer part 10 'on the inside a cylindrical recess 20, and the inner part 20' has a corresponding cylindrical pin 23.
  • the pin 23 in the recess 22 a engages the pin 23 in the recess 22 a.
  • the engagement is effected by a cone 25, which is centered in the rest position on a corresponding recess 26. Also in the tumblers Z1 'and Z1 ", the parts 10' and 20 'or 10" and 20 "are each loose to each other and thus can be completely separated from each other according to the said percussion principle.
