  • additional locking means are provided and comprise second core pins to be received in a plurality of recesses in the edge of the key.
  • the additional locking means comprise a core pin which extends into the key passage, and is operated by a first side of a first end of a pivotably mounted lever. The other side of the first end of the lever is received in a duct in the shell. The second end of the lever is biased into a corresponding bore in the shell by a spring.
  • the additional locking means are displaced radially with respect to the first locking means. In longitudinal direction of the lock, a plurality of first and additional locking means may be provided.
  • the first locking pin When inserting the correct key in the lock, the first locking pin is received in a corresponding recess in the key shaft, the pin clears the shell and meets the surface of the core.
  • the core pin is received in the corresponding recess, following which the second end of the lever is biased towards the shell such that the surface of both the first and second end of the lever meet the surface of the core. The core may now be rotated.
  • FR-A-2.263.360 an assembly of a cylinder lock and a key with an improved security is disclosed.
  • the key has along its sides at least one additional longitudinally extending groove into which recesses, provided to be explored by safety pins, protrude.
  • the lock comprises a housing with a rotatably mounted cylinder.
  • first and second ducts receive first locking pins and safety locking pins.
  • the second ducts extend into the housing.
  • first pins located in the vicinity of the entrance and associated with the longitudinal grooves clear the housing and are received in corresponding holes of the cylinder core.
  • second safety pins are mounted in the direction of the interior of the lock. The second safety pins are provided to be received in a corresponding recess on the key. At this point, the safety pins clear the housing and the cylinder may be rotated with respect to the housing.
  • Revolving cylinder locks equipped with radial locking pins are sometimes opened fraudulently, by inserting an external object, by which the locking pins are pushed in the release position.
  • the cylinder lock comprises apart from the known locking pins, additional blocking means.
  • the key shows a longitudinally extending rib, having such cross sections that in a position where the key is completely inserted into the stator, the key pushes the additional blocking means in a release position, thus enabling the rotation of the cylinder rotor in the cylinder stator as described in the characterising part of the first claim.
  • the additional blocking means comprise at least one sequence of first and second additional blocking means spaced from each other in longitudinal direction of the lock.
  • the first additional blocking means are positioned distal from the key entrance and comprise at least one active pin which is biased towards the key passage by a spring, and is displaceable within a first duct in radial direction of the cylinder lock.
  • the second additional blocking means comprise at least one passive pin moveable in radial direction of the cylinder lock, within a second duct radially extending from the rotor into the stator.
  • the second additional blocking means are positioned proximal to the key entrance, the active and passive pin being operable by a corresponding sequence of a first and second notch provided in a longitudinally extending rib on the key, taken in longitudinal direction of the key. Thereby the second notch for operating the passive pin is deeper than the first notch for operating the active pin.
  • the active pin is preferably a two-part pin, of which the first part, which can be moved radially and under the influence of a compression spring into and out of the stator, co-operates with a second part of said pin, which second part is in contact by one extremity with above said rib of above said key, which locally, i.e. at the height of said active pin, when the key is completely inserted, shows a notch, through which the height of said second part influences the position of the first part of the active pin which is contacting it, with respect to stator and rotor.
  • above said additional blocking means are formed by at least one radial passive pin, i.e. a pin which can be moved into and out of above said rotor, which by a conical extremity is in contact with above said rib of above said key, which locally, i.e. at the height of said passive pin, when the key is completely inserted, shows a notch, through which the position of said passive pin with respect to stator and rotor is modified, by moving this pin upon rotation of the key, of which the rib pushes against above said conical extremity.
  • radial passive pin i.e. a pin which can be moved into and out of above said rotor, which by a conical extremity is in contact with above said rib of above said key, which locally, i.e. at the height of said passive pin, when the key is completely inserted, shows a notch, through which the position of said passive pin with respect to stator and rotor is modified, by moving this pin upon rotation of the key, of which the rib pushes
  • above said radial active and passive pins are provided in such a way in above said stator and rotor, that their central axis defines an angle of almost 135° with that of above said locking pins.
  • Figure 1 is a side view of the key according to the invention.
  • Figure 2 is a top view of the key according to the invention.
  • Figure 3 is a cross section along the line III-III in figure 1.
  • Figure 4 is a cross section along the line IV-IV in figure 1.
  • Figure 5 is a perspective representation of the key according to the invention.
  • Figure 6 is, on a larger scale, a cross section of a part of the revolving cylinder lock at the height of an active pin.
  • Figure 7 is, on a larger scale, a cross section of a part of the revolving cylinder lock, at the height of a passive pin.
  • the revolving cylinder lock according to the invention consists of a stator 1, in which the rotor 2 can be rotated along the longitudinal axis of the rotor by means of a key with rib.
  • the radial locking pins which keep the rotor blocked in locking position, are of a common type and will not be described hereafter.
  • both the key and the lock play an essential role.
  • the revolving cylinder lock according to the invention is provided with additional blocking means, consisting of at least one, but in the embodiment example described here, of two active and two passive pins.
  • the active pins are radially applied two-part pins of which the first part, 3, forms a barrel bearing a compression spring 4 which radially pushes away said first part in the direction of a second part 5, the operation of which will be discussed further.
  • the first part 3 of the active pin is moved radially through the stator and this within a stopper 6 fixed in the stator.
  • the compression spring 4 pushes the first part 3 of the active pin out of the stator, this first part will make any rotation of the rotor with respect to the stator impossible.
  • Such a locking position is only possible when the second part 5 of the two-part active pin is completely pushed into the rotor 2.
  • first part 3 and the second part 5 which compose the active pin are each movable in a radial bore.
  • the bore in the stator 1 in which the first part 3 is moving, has reference 7, while the bore in the rotor 2 in which the second part 5 is moving, has reference 8.
  • the second part 5 of the active pin has at one extremity a conical head 5'. This extremity 5' is in contact with the rib 9 of the key 10.
  • the position of the second part 5 of the active pin with respect to rotor and stator is determined by the profile of the key 10 which was designed within the frame of this invention, more particularly by the profile of the rib 9 of this key.
  • This rib 9 performs a very remarkable function and shows for each active pin a notch 11 being formed by removing material from the rib 9.
  • two active pins are present.
  • the notches 11 for receiving each time the extremities 5' of the second part of the active pins show a chamfered edge by which the key 10 may slide along unhindered.
  • At least one passive pin 12 is provided in the revolving cylinder lock according to the invention.
  • two passive pins 12 are present.
  • the passive pins aim at preventing the fraudulent activation of the active pins by the key with continuous rib or by simulating this rib with a needle or a thin object. If in such a situation, the active pin would be released, the passive pin would prevent the rotation of the rotor in the stator.
  • the passive pins 12 show two conical heads 12' and 12".
  • the passive pins may be moved through a bore 13 in the stator 1 and through a bore 14 in the rotor 2.
  • the bore 13 is sealed by a stopper 15.
  • the passive pin 12 When the key 10 is in the completely inserted position, the passive pin 12 has reached its lowest position, as represented in figure 7.
  • the notches provided in the rib 9 are located such, that upon complete insertion of the key, the passive pins 12 may sink into their respective notches, while the two-part active pins have reached their highest position.
  • the first part 3 of an active pin, against the action of a compression spring 4 is in its fully retreated position in the stator 1.
  • the lock is in the release position.
  • the notches 11 designed for the active pins are less deep-in the rib 9 than the notches 16 designed to receive the passive pins 12. The difference may be deduced from the figures.
  • the plane in which the active and passive pins extend defines an angle of almost 135° with the plane in which the locking pins move.
