Definitions

  • the invention relates to a cylinder lock with a sliding cylinder core and bolt lock in the locking position, which is particularly, but not exclusively, intended for steering locks on motor vehicles.
  • the aim of the invention is to obtain a simple and economical locking means for the bolt in the locked position in a cylinder lock with a sliding cylinder core.
  • the lock according to the invention is characterized in that it comprises a hook which tilts against the action of a spring about an axis perpendicular to the axis of the cylinder core, namely between a first position in which the free end of the hook is adjacent to the free end the bolt or a tie rod is in fixed connection with said bolt when it is displaced, and a second position in which the free end of said hook escapes to said bolt, a shoulder of the cylinder core being supported on a projection of said hook , so that the hook is tilted in the sliding course of the cylinder core from the first to the second position.
  • the device according to the invention uses a simple and economical part with a return spring, which can be a simple, bent-over spring part which is welded to the part, thereby ensuring simple installation and safe operation.
  • the hook includes a nose in support of a shoulder of a cam which is coupled to the cylinder core after the key has been inserted, whereby the tilting axis of the hook is formed without its attachment with respect to a fixed part.
  • Tilting the hook due to the sliding of the cylinder core also enables security against turning the lock to be maintained.
  • the lock comprises a cylinder housing 1, in which a cylinder core 2 rotates, which can slide axially against the action of a spring 2 when the pairs of pins 3-4 are shifted by a suitable key 5 such that their connection planes are in the jacket of the cylinder core 2 are ( Figures 2, 3, 4). Without a suitable key (FIG. 1), the cylinder core is stuck with respect to the cylinder housing 1 against rotation and linear movement.
  • the cylinder core 2 actuates a bolt 6 via a cam 7, which is coupled to the cylinder core 2 only after its rectilinear movement and acts on the neck of a tension rod 9 which is firmly connected to the bolt 6 in a rectilinear movement.
  • a return spring 10 wants to bring the bolt 6 into the locking position, and a sensor group 11 of the key 5 holds the bolt 6 in the unlocking position as long as the key is in the key channel 12 of the cylinder core 2.
  • a hook 13 is installed, which can be rotated by a lug 14 in support against a circular shoulder 15 of the cam 7 and is subjected to the force of a spring 16, which is formed by a spring bed bent and welded to the hook 13.
  • a projection 17 of the hook 13 lies in the path of a shoulder 18 of the cylinder core 2.
  • the hook 13 In the locking position (FIG. 1), the hook 13 is tilted such that its free end 13 ′ lies directly next to the free end of the tension rod 9, it being impossible for the bolt 6 to be pressed in against the action of its spring 10. Since the cam 7 is not coupled to the cylinder core 2, the bolt cannot be pulled back in the event of a violent rotation of the cylinder core by shearing off the pins 3-4.
  • the cylinder core 2 comprises a tongue 19 (FIG. 2) which cooperates with a groove 20 in the cylinder housing, as a result of which a straight-line movement of the cylinder core is only possible in the rest position, so that a violent turning becomes even more difficult.
