This takes place in the closing direction Transfer of the actuation forces to the lock bit by frictional engagement of the friction plates preloaded against each other. Therefore, the locking cylinder can be blocked Unlock the core over the opposite core.
  • the double lock cylinder can be constructed symmetrically and the cores each with the invention Coupling device to be equipped. This design also has the advantage of easy disassembly of the Lock cylinder from a lock in a locked Position blocked core.
  • the coupling device according to the invention can in particular simply retrofit for very long locking cylinders, if the friction plates on one between the core and the intermediate piece to be arranged in the locking bar are. With a preferably pot-shaped design of the intermediate piece can also be prevented that the Lock bit with one inserted into the locking channel Wire is blocked.
  • the coupling device according to the invention is designed particularly compact if the slip clutch is at least one Has disc spring.
  • the preload of the friction plates made possible by means of one or more disc springs an advantageous use of the space in the double locking cylinder, because disc springs like the kernels round off Have a cross-section and therefore simply fill in the space Housing can be inserted.
  • the lock cylinder With a lock bit twisted relative to the core the lock cylinder according to another advantageous Further development of the invention still unlock if the spring travel of the disc spring or disc springs is larger is the height of the clutch engagement member. in this connection the clutch engaging member arrives when inserting the Key in the locking channel first on the front the mustache. Snaps when turning the clutch engaging member in the corresponding receptacle of the lock bit when the rotational positions of the core and of the lock bit match.
  • the second problem namely the creation of a Lock cylinder, which from a designated side unlocked even when the opposite core is blocked can be solved according to the invention in that between one of the cores and the mustache Slip clutch is arranged and the other core at least in the unlocking direction with the Lock bit is connectable.
  • This design allows the locking cylinder to be opened at any time of which the form-fitting with the lock bit Unlock the core that can be connected to the core.
  • a Blocking the opposite core does not lead to a blockage of the movement of the lock bit, because the Slipping clutch slips if appropriately designed.
  • Figure 1 shows a double lock cylinder with two in one Housing 1 rotatable cores 2, 3. Between the cores 2, 3, a lock bit 4 is arranged, which at one Insertion of keys 5, 6 shown in Figure 2 Locking channels 7 with the cores 2, 3 can be coupled in a rotationally fixed manner is.
  • Figure 2 shows enlarged in a sectional view through the lock cylinder in the area of a coupling device 8 of the lock bit 4 with the core 2.
