Definitions

  • the invention relates to a lock for prison doors with at least one guard locking set from locking devices that can be operated directly with a key, Locking tumblers which can be fixed on a locking pin of the lock plate and between these arranged tumblers that can be lifted on the Bolt shaft guided and guided by those liftable on a support plate Locking tumblers for changing the lock using a changeover rod can be uncoupled, which is non-positively connected to the locking shaft by a spring connected support plate against a return movement of the bolt holds the force of this spring in its front end position, the Changeover bar with the door open by a trained in the lock faceplate Opening can be actuated by means of a tool.
  • Convertible locks for prison doors are known from DE-AS 1 156 674. You have a high level of security due to the changeability of the lock against unauthorized opening of the prison doors.
  • a disadvantage of the known locks is, however, that when withdrawn Bolt unintentionally a change in the closure can be excluded if the bolt is locked with another key is because a change of closure takes place automatically when the withdrawn bolt with another key is excluded. There it is not recognizable with which closure the bolt was excluded, This can cause difficulties if the latch turns back into its retracted position Position should be transferred.
  • a castle in which a changeover guard lock between each guard locking and locking guard locking is arranged, which can be raised on the bolt shaft and via a Coupling can be coupled with the locking tumbler and has a toothing is releasably connected to the locking device, which in turn can be raised on a Carrier plate is guided, which with normal operation of the bolt at least one spring non-positively connected to the bolt, but for Change of the lock against the force of the spring when pulling back of the excluded bolt can be set in its front end position.
  • the Fixing the support plate in its front end position by means of a changeover rod, which is adjustable against the force of a return spring when the door is open is arranged in the castle.
  • This switch rod is preferred adjustable in height on guide pins of the lock plate and over a coupling hook can be coupled to the support plate.
  • the object of the invention is to prevent manipulation by unauthorized actuation of the changeover rod in a lock of the type defined at the beginning for prison doors.
  • the solution to this problem by the invention is characterized in that the opening provided in the lock face plate for actuating the changeover rod is closed by a cover when the bolt is withdrawn.
  • the cover according to the invention prevents that when both open Even with the door closed, manipulations at the lock through the faceplate opening can be made through.
  • the cover is between one Cover and a release position movable through the bolt shaft, see above that an inevitable securing of the faceplate opening together with the actuation of the bolt is made.
  • the cover is as angled cover plate with an extending parallel to the faceplate Cover part and a guide part extending parallel to the locking shaft educated.
  • the guide part of the cover plate is according to the invention by means of an elongated hole parallel to the faceplate on a guide pin of the Lock plate movably supported.
  • a control pin engaging in a control slot is arranged so that easily forced movement of the cover between Cover and release position results solely from an actuation of the bolt.
  • the lock shown in the drawings only with its lower half comprises a lock plate 1, at the front, angled edge of one Forend 2 is attached. An opening in the faceplate 2 protrudes from the front End of a locking shaft 3 formed locking head 3a.
  • the bolt shaft 3 is slidably supported on guide pins 1a via elongated holes 3b, which are attached to the lock plate 1.
  • the lock plate 1 is still with Provide threaded bushings 1b.
  • a key S which is shown in dashed lines in Figures 1 and 3 and is attached to a key pin 1c arranged on the lock plate 1 becomes.
  • This designed as a double-bit key in the embodiment Key S acts on locking tumblers 4, which have elongated holes 4a height-adjustable on the same guide pins 1a as the locking shaft 3 Lock plate 1 are stored.
  • the locking tumblers 4 are for interaction with the key bit of the key S each with a tumbler channel executed. In the area of this tumbler channel are on the Lock plate 1 two stop pins 1d arranged, the twisting of the Prevent key S in the wrong direction of rotation.
  • Each locking tumbler 4 acts with a via a coupling channel 4b
  • Coupling piece 5a of a changeover tumbler 5, which has elongated holes 5b are vertically adjustable on bearing pins 3c of the locking shaft 3.
  • Each diverter lock acts via a toothing on the front edge 5 together with teeth of a locking tumbler 6.
  • the blocking tumblers 6 are adjustable in height by means of elongated holes 6a on guide pins 7a of a support plate 7 performed which below the locking shaft 3 between the Bolt shaft 3 and the lock plate 1 is arranged.
  • the in the slots 6a of the locking tumblers 6 engaging guide pins 7a of the support plate 7 pass through elongated holes 3d, which are arranged on the locking shaft 3.
  • the locking tumblers 6 are formed with an incision 6b with which they can be fixed on a mandrel 1e. These mandrels 1e are on the Lock plate 1 arranged.
  • a tension spring 8 is arranged, which in the exemplary embodiment is a helical spring formed and with one end on a spring mandrel 3e on the locking shaft 3 and hung with the other end on a spring mandrel 7b of the support plate 7 is.
  • the spring mandrel 7b of the support plate 7 engages through an elongated hole 3f in Bolt shaft 3 through.
  • the support plate 7 at its upper, not in the drawing illustrated end provided with a coupling hook, which also with a Coupling hook, not shown, of a changeover rod 9 interacts.
  • This switch rod 9 is on slots 9a on guide pins 1f of the lock plate 1 vertically guided and by a return spring 9b charged.
  • the changeover rod 9 is provided with a driver 9c, which has a hole 9d for attaching a Has tool.
  • a driver 9c which has a hole 9d for attaching a Has tool.
  • a Has tool for example a pen
  • the faceplate 2 provided with an actuation opening 2a.
  • the changeover rod 9 via its driver 9c actuated through the actuation opening 2a in the faceplate 2 can be, the actuation opening 2a is normally through a cover 10 closed.
  • this cover 10 from a cover plate with a parallel to the faceplate 2 extending cover part 10a and one at right angles thereto, that is Guide part 10b extending parallel to the locking shaft 3a.
  • This guide part 10b of the cover 10 is by means of an elongated hole 10c on a Guide pin 1g of the lock plate 1 parallel to the longitudinal extension of the faceplate 2 movably mounted so that the cover 10 is either that shown in FIGS and 2 shown cover position or that shown in FIGS. 3 and 4 Can take release position.
  • the Extension 11 with an exclusion of the bolt head 3a together with the locking shaft 3 from the retracted to the locked position.
  • the control slot 11a of the extension 11 pulls over the control pin 10d the cover 10 down so that the cover member 10a in position 3, the actuating opening with the bolt head 3a excluded 2a in the faceplate 2 releases.
  • the changeover rod 9 can thus be tool used in the bore 9d of the driver 9c the force of the return springs 9b are raised to the support plate 7 hold with the locking tumblers 6 in the front end position, so that with a subsequent withdrawal movement of the bolt, a separation between the change tumblers 5 and those defined on the mandrel 1e Locking tumblers 6 takes place.
