Definitions
- the invention relates to a rotary lock cylinder for a Security lock, with a cylinder housing and an in this mounted rotor and with tumblers in radial Drilled holes in the rotor and cylinder housing Have pens.
- Rotary lock cylinders of this type have been known for a long time. These are provided with a flat key with holes or a so-called wrench.
- the unlocking security of such rotary lock cylinders is especially affected by the so-called "electric picking".
- the specialist understands unlocking security as Degree of aggravation, the tumblers of a rotary lock cylinder non-violent with aids without knowledge of the related To overcome the key non-destructively.
- the tumblers become radial due to vibration moved outwards until all housing pins are behind the lying shoulder formed by the rotation of the rotor and the rotor is finally released for rotation.
- a Difficulty of such unauthorized unlocking attempts required So far very expensive measures and accordingly expensive cylinders.
- the invention has for its object a rotary lock cylinder to create the type mentioned, in which the unlocking attempts mentioned are considerably more difficult and yet it is only marginally more expensive to manufacture is.
- the rotary lock cylinder 1 shown in Figure 1 has one housing 17 known per se, in which a rotor 9 is mounted is. There are rotor pins 8 in radial bores 11, 12 and 13 and in known sliders 2 of the housing 17 each with a spring 4 loaded housing pins 3. If a key is not shown here in the Key channel 10 introduced, the rotor pins 3 and the housing pins 4 arranged with respect to the shear line 5 and thereby the rotor 9 released for rotation. So far the rotary lock cylinder 1 is well known per se.
- Rotor bores 11, 12 and 13 each at their radial outer end with a countersink 14, 15 or 16 step-shaped expanded.
- the diameters of these cruciform countersinks are, as can be seen, different and judge after the rotor game. With a rotary lock cylinder with large rotor play, these countersinks are corresponding further than a rotary lock cylinder with a small rotor clearance.
- the diameters are, for example, 3.3, 3.4 and 3.5 mm, for housing pins with a diameter of 3.1 mm.
- the bores 11, 12 and 13 are around expanded by an amount of 0.2, 0.3 or 0.4 mm.
- the depth the countersinks 14, 15 and 16 are preferably smaller than 1 mm, for example 0.7 mm.
- the rotary lock cylinder 1 naturally has much more tumblers as shown. Since the countersinks 14, 15 and 16 are very simple can be made, it is at no significant cost possible to drill all holes with such countersinks Mistake. A significant complication is also given if not all rotor bores such countersinks exhibit.
- the rotary lock cylinder 30 shown in Figure 2 differs differs from the rotary lock cylinder 1 in that slide 21, 22 and 23 in the area of the shear line 5 extensions 23, 24 or 25, which are preferably designed differently are and for some of the radial bores 27 for the housing pins 3 may be missing.
- Extensions 23, 24 and 25 have the effect that at one above Unlocking attempt rotor pins 3 at the outer end of the Shear line 5 does not stand in line, but pushed beyond it lock the cylinder.
- the extensions 23, 24 and 25 can counterbores the holes 27th be and are dimensioned so that the radial guidance of the housing pins 3 are guaranteed in the holes 27.
- the lock cylinder 30 also has one in the housing 17 to the shear line 5 open longitudinal channel 28 in which a Locking member 29 is mounted, which with a shoulder 31 in the Closing channel 10 engages and against the retroactive force a compression spring 32 is movable downwards.
- the blocking organ 29 when inserting a key into the locking channel 10 moved down to a position in which the Approach 31 no longer engages in the key channel 10 and therefore no longer locks.
- the blocking element In one of the unlocking attempts mentioned above the blocking element must now be replaced by another Instrument against the force of the spring 32 constantly down be pressed, which further complicates the attempt and thus increasing the amount of time.
- the organ 31 extends preferably substantially over the entire length of the channel 10 and can consist of several parts as well as several compression springs consist.
