Definitions

  • the invention is directed to a lock cylinder in the preamble of Such type of locking cylinder are e.g. at Locks used for automotive or front doors.
  • the key also performs a distracting key Axial movement.
  • the axial movement of the rotor corresponds approximately to that half the distance between two adjacent tumbler channels. After a 180 ° rotation therefore aligns the front ends of the tumblers with the web walls, which in the zero position of the rotor radially with the Distances between the tumbler channels of the rotor are aligned. As a result, the tumblers can no longer be in the 180 ° position of the rotor dodge into the free spaces of the stator between the webs. The Withdrawal of the key is therefore blocked.
  • the invention has for its object a reliable Lock cylinder without axially movable rotor or key in the The preamble of claim 1 to develop the type mentioned Key removal in a position other than the intended turning position impossible makes. This is according to the invention by those mentioned in claim 1 Measures achieved, which have the following special importance.
  • closure means which e.g. as a plate or as a sleeve with it arranged breakthroughs can be carried out via controls between those that release the tumbler channels and those that Locking channels moved completely or partially covering layers.
  • closure means as a plate
  • this can e.g. be guided in a longitudinally displaceable manner along the cylinder axis in the cylinder jacket.
  • this is guided in a longitudinally displaceable manner between the cylinder core and the cylinder jacket his.
  • Lock cylinder By arranging the closure means in a recess of the Cylinder jacket is a compact design of the invention Lock cylinder enables. Also by e.g. the arrangement of the Closure means in a recess in the cylinder core is a comparable compact design enables.
  • a Lock cylinder 10 includes a cylinder jacket or stator 21 and one therein rotatably mounted cylinder core or rotor 11, which is a key channel 41 has a suitable key 40 inserted into it.
  • tumbler channels 12 are embedded which are shown in FIG are arranged in a row and perpendicular to the longitudinal axis of the Cylinder core 11 are aligned.
  • Tumblers 16 arranged in the direction of the cylinder jacket 21 are spring loaded.
  • the tumblers 16 in the tumbler channels 12 are such sorted that a rotation of the cylinder core 11 in the cylinder jacket 21 possible is.
  • the tumblers 16 partially protrude from the Tumbler channels 12 out and into the jacket-side tumbler channels 32 into it, so that rotation of the cylinder core 11 in the cylinder jacket 21 is not is possible.
  • a transmission member 19 arranged, which an actuating movement of the cylinder core 11 e.g. to a Lock can transfer.
  • a head part 14 which is connected to the cylinder core 11 is molded.
  • This head part 14 has at least in some areas larger diameter than the actual cylinder core 11 and covered therefore the lateral surface 13 of the cylinder core 11 in the front region of the Cylinder core 11.
  • a closure means 30 is arranged in this channel 22, which is designed as plate 31 in the present exemplary embodiment.
  • openings 32 are arranged, which in the present Embodiment act as a tumbler ducts.
  • Spring elements 34 are arranged, via which the plate 31 resiliently against supports an end surface 24 of the channel 22.
  • a scanning element 35 which on the control surface 15 of the Head part 14 abuts.
  • the plate 31 is now in the position shown in FIG 2 and 4 shown release position 38. In this it is possible to disengage the tumblers 16 from the tumbler channels 12 into the openings 32 in the plate 31 when the key is in its key withdrawal position.
  • the scanning element 35 moves from the recess 17 onto the raised surface 18 of the control surface 15, the plate 31 is displaced in the direction of the arrow 25 by a predetermined path against the spring loading of the springs 34. This path corresponds exactly to the movement required to position the openings 32 exactly above the tumbler channels 12 in the cylinder core 11 when the key is in its key withdrawal position.
  • the invention is in a second embodiment shown.
  • This points to Closure means 30 'in turn a scanning element 35 at its front end 36 on which is then moved into the recess 17 on the control surface 15 (see FIGS. 7 and 5).
