Definitions

  • the invention relates to a rotary lock cylinder according to the preamble of independent claim 1.
  • a rotary lock cylinder of this type is known from DE-A-35 03 570. This discloses a codable locking cylinder with at least two shear surfaces or coding disks for changing the locking code. Since the shearing surfaces between the rotor core and the rotor position are used when changing the locking code, the locking channel is not closed when further locking levels (locking level 35 ') are occupied. The rotor position therefore does not create a complete and, in any case, closed key channel. So that the rotor position can accommodate coding elements and a compression spring, it must have a thickness of at least half a centimeter. Such a locking cylinder is obviously much more complex to manufacture and correspondingly more expensive than a conventional locking cylinder and also has a special external dimension.
  • the invention has for its object to provide a lock cylinder which has the advantages of an internally cleared, closed key channel, but which can be manufactured much more cost-effectively and easily.
  • the outer rotor position is formed by a sleeve with a wall thickness less than or equal to 1 mm.
  • the wall thickness is so small here that the outside diameter of the rotor is not larger than usual. Changes to the cylinder housing are therefore not required in the rotary lock cylinder according to the invention.
  • the lock cylinder according to the invention has only a single shear surface between the outer surface of the sleeve and the cylinder housing.
  • the key channel is thus closed in any case and has at least the advantages of a key channel cleared inside.
  • the sleeve is fixedly and immovably connected to the rotor.
  • a cylinder core with a closed key channel is created with structurally particularly simple means.
  • the cylindrical body of the cylinder core which can consist of brass, is provided with a key channel that is open to the outside in cross section.
  • the slotted core is now covered by sliding on a closed sleeve on the circumference of the cylinder core.
  • the housing pins slide on this closed sleeve and, regardless of the design of the key channels or due to the wear of the key, can no longer engage in the key channel and thereby jam.
  • the sleeve can now be firmly connected to the core. If the safety value is high, the sleeve is placed loosely, freely floating on the core. When the rotor is rotated, the loose sleeve also rotates because it is pulled along by the core pins that engage through the sleeve. Due to the movement of the tumblers, the sleeve is automatically centered each time the locking cylinder is actuated.
  • the core pins do not remain in such an unauthorized opening attempt until they have passed the loose sleeve, ie, only when they are completely in the solid core at the closing height. But as soon as the first housing pin the shear surface between the cylinder housing and more mobile If the sleeve has exceeded, this unauthorized attempt to open fails, since the sleeve is secured against rotation by a certain core pin.
  • the closed sleeve also largely prevents contamination of the housing pins and springs.
  • the dust and dirt collected in the key guide is transported with the milled or cleared edge when the core is turned and deposited on the core / housing through-holes. By moving the core and housing pins, these dust and dirt particles are transported to the springs.
  • the development according to claim 2 ensures that even when the key is pulled out, that is when all core pins are immersed in the core, the movable sleeve is pulled along when the cylindrical core is rotated.
  • the locking cylinder shown in FIGS. 1-3 has a stationary cylinder housing 2, which is enclosed by a coaxial sleeve 5, and a cylinder core 1, which is mounted centrically or eccentrically therein.
  • the two parts 1 and 2 contain radially or non-radially arranged bores 9, in which tumblers loaded with or without springs 6, for example each from a core pin 8 and a housing pin 7 are mounted.
  • the tumblers are arranged by a key 13, the shaft of which has a cross-sectional shape that corresponds to the cross-section of the key channel 3.
  • the cylinder core 1 has a cylindrical body 11 which is enclosed by a coaxial, preferably loose sleeve 4.
  • the sleeve 4 can have an axial play (X) and centers itself.
  • the cylindrical body 11 is preferably made of brass or nickel silver, while the sleeves 4 can be fixed or loose from another material, for example hardened steel.
  • the shear surface of the locking cylinder is thus located on the outer surface 10 of the sleeve 4.
  • the key channel 3 is enclosed by the cylindrical body 11 and by the sleeve 4 essentially over its entire length, the cylindrical body 11 having a slot 3a milled from the side (open core).
  • the housing pins 7 are on the outer surface the sleeve 4 and come into contact neither with the inserted key 13 nor with an edge of the key channel 3.
  • the housing pins 7 can therefore also not hook onto the cylinder core 11 and are correspondingly less worn, tilted or deformed, ie the operational safety increases considerably.
  • the sleeve 4 preferably sits loosely with axial play on the body 11 or, as shown in FIG. 4, on a tightly fitting sleeve 4a, so that it can be displaced in relation to the latter in the circumferential direction in the region of the radial play of the tumbler pins 7 and 8 . If the cylinder core 11 is moved in the event of an unauthorized attempt to open it, and the tumbler pins pushed outwards are thereby moved inwards, the core pins 8 do not remain as they were previously in the cylinder core 1, but instead are moved by the sleeve 4, which moves relative to the cylindrical body 11 driven further inwards to the dividing line of the solid core, the associated housing pins 7 immediately locking the locking cylinder.
  • the wall of the sleeve 4 or 4a determines the position of the key channel 3 because the key back is always supported on the sleeve 4 or 4a.
  • the Key channel 3 can be moved vertically over the entire core 11, depending on the cylinder system. If the thickness of the sleeve 4a is varied while the cross-section of the key guide 3a remains the same and the outer diameter of the cylinder core is the same, the radial distance of the key channel 3 from the outer surface of the cylinder core 1 is also changed, which leads to a significant increase in the number of different locking options.
  • the wall thickness of the movable sleeve should move between 0.5-1 mm, in the case of thicker sleeves a fixed sleeve 4a, which is connected to the core 11 in a rotationally fixed manner, and a movable sleeve 4 are arranged.
  • the sleeve 4 can consist of one piece or, as shown in FIG. 6, of two halves 14a and 14b separated by a narrow slot 12 of 0.2-0.3 mm.
  • a hardened sleeve 4 offers excellent protection against drilling, since the dividing line between core 11 and housing, the locking line and the shear line are protected over the entire length.
