Definitions

  • the invention relates to a closure device in the classifying Part specified by claim 1.
  • the key rotation of the cylinder core from one radial slide to one transmitters interacting with lock members, but at violent turning of the locking cylinder in the area of the driver is interrupted, because this is from a pestle against one acting on it Spring load is offset.
  • the plunger is part of an overload lock, those in the adjacent components both enclose the ram Radial breakthrough as well as a receiving only the radial end of the plunger Have radial recess.
  • the radial recess is from run-up curves limits which when one component rotates lift the plunger end out of the radial recess.
  • the plunger has the task of turning the key of the cylinder core to fix the cylinder guide in the housing, but the Cylinder guide to be freewheel when the locking cylinder is over a The burglar tool or the like is rotated by force.
  • This known device consists of numerous components, one tedious assembly and a correspondingly large amount of space required. It is difficult to reliably move the bolt that can be moved in the driver to connect with the radial slide in the cylinder core. For a trouble-free Interaction of the components requires a relatively large amount of play.
  • EP 0 444 972 B1 which is not corresponds to the classifying part of claim 1, is the cylinder core, which carries the spring-loaded tumblers instead of in a cylinder guide pivoted directly in the housing.
  • An overload lock is therefore also missing belonging tappet, which at a certain, on the cylinder core exerted torque, from a also belonging to the overload lock Radial recess is lifted out and thereby the overload lock in sets their freewheel position.

  • the latch's nose can then fall into the notches.
  • a rotation of the cylinder core can then over the finger of the pivoting latch on the driver be transmitted.
  • Closure device has a relatively large number of complicated ones Components that can cause malfunctions in operation and an expensive one Individual production and assembly require. You can't rely on conventional Use cylinder cores with cylinder guides, but required special shapes with integrated bearing points for the bolt and special ones Longitudinal grooves for reaching through the scanning nose from the bolt. Also require the tumblers also have a special shape, namely the arrangement of additional ones Notches that are in line with the control surfaces for the key must be introduced. All of this makes the manufacture of such closure devices expensive.
