Definitions

  • the invention relates to a double locking cylinder with a coaxial between the two closing cores arranged closing member and with one two coupling elements each having a spring element Coupling for the rotational connection of the cylinder core and locking element, one inserted into the key channel of the one cylinder core Key with its tip the spring element of this cylinder core rotatably assigned coupling element.
  • Double locking cylinders of the type in question are known per se.
  • the German utility model 19 929 05 describes such a double locking cylinder, the structure of the double locking cylinder described there essentially corresponds to the state of the art.
  • the essential to the invention Thought of this utility model is there on the design and arrangement of the coupling members turned off to the closing member.
  • the latter spring-loaded coupling elements occur with a keyless one State of the double locking cylinder locking in a positive connection with the locking member so that the latter is not in the keyless state is freely rotatable.
  • One of the two cylinder cores is fitted with a key the key tip shifts the one assigned to the cylinder core with one Spring element equipped, coupling member such that this is associated with the Opposing spring-loaded other coupling member other than positive locking brings with the locking member, what a free rotation of the locking member when the key is turned.
  • the invention is based, the generic double lock cylinder the task to improve.
  • the task is solved by a between the two coupling elements arranged compression spring, the spring force is less than the spring force of the Spring elements.
  • the two coupling elements are only in indirect attachment to each other. This makes them more advantageous Way the coupling elements with the key not inserted in such a way spaced from the compression spring that the closing member is freely rotatable. This proves itself in particular when mounting the double locking cylinder in a lock arranged in a door leaf is an advantage. The user can do this easily turn the freely rotatable locking element by hand, so that its outer contour matches the outer contour of the cylinder housing escapes to then the well-known installation of such a double locking cylinder make.
  • the positive engagement by engagement of a radial extension of the Coupling element can be achieved in a radial recess of the closing member. It is further preferably provided that the radial recess is in the out of alignment position lying radial extension the key tip of the inserted key the spring element tensions such that after a relative rotation in the cylinder core and the closing element when the escape position is reached, the coupling element shifted to the clutch position.
  • the spring element can be used as a leaf spring be trained.
  • the spring element is a Foam body is, the training as a foam body has the advantage possesses that with long-term use of the double locking cylinder counteracted the mechanical signs of wear at the tip of the key is.
