Definitions

  • the invention relates to a lock for prison doors with at least one tumbler set of lock tumblers which can be actuated directly by a key, locking tumblers which can be fixed on a retaining pin of the lock plate and shift tumblers arranged between these, which can be lifted on the bolt shaft and can be lifted by the locking tumblers on a support plate for changing over the Closure can be uncoupled by means of a changeover rod, which holds the support plate, which is connected to the locking shaft in a force-locking manner by a spring, during a retraction movement of the lock against the force of this spring in its front end position, the changeover rod with an open door through an opening formed in the lock faceplate by means of a Tool is actuated.
  • Convertible locks for prison doors are known from DE-AS 1 156 674. Due to the adjustability of the lock, you have a high level of security against unauthorized opening of the prison doors.
  • a disadvantage of the known locks can be seen in the fact that, when the bolt is withdrawn, a change in the locking can be carried out unintentionally if the bolt is excluded with another key, because a change in the locking mechanism takes place automatically if the withdrawn bolt is excluded with another key . Since it cannot be seen with which closure the bolt was excluded, this can lead to difficulties if the bolt is to be moved back to its retracted position.
  • a lock was created in which a changeover lock, which can be lifted, is arranged between each locking lock and locking lock guided on the bolt shaft and can be coupled to the locking tumbler via a coupling and which is releasably connected to the locking tumbler via a toothing, which in turn can be raised on a support plate which is non-positively connected to the bolt by at least one spring when the bolt is operated normally, but can be set to change the closure against the force of the spring when retracting the excluded bolt in its front end position.
  • the support plate is fixed in its front end position by means of a changeover rod which, when the door is open, is adjustably arranged in the lock against the force of a return spring.
  • This changeover rod is preferably adjustable in height on guide pins of the lock plate and can be coupled to the support plate via a coupling hook.
  • the invention has for its object to exclude at an intended for prison doors lock of the initially defined type manipulation by unauthorized operation of the shift rod.
  • the solution to this problem by the invention is characterized in that in the lock face plate for actuating the changeover rod intended opening is closed by a cover when the bolt is retracted.
  • the cover according to the invention prevents tampering with the lock through the faceplate opening both when the door is open and when it is closed.
  • the cover can be moved between a cover and a release position by the bolt shaft, so that the forend opening is inevitably secured together with the actuation of the bolt.
  • the cover is designed as an angled cover plate with a cover part extending parallel to the faceplate and a guide part extending parallel to the locking shaft.
  • the guide part of the cover plate is movably mounted on a guide pin of the lock plate parallel to the faceplate by means of an elongated hole.
  • a control mandrel engaging in a control slot is arranged between the guide part of the cover plate and an extension of the locking shaft, so that a forced movement of the cover between the cover and release positions results simply from actuation of the lock.
  • the lock shown in the drawings only with its lower half comprises a lock plate 1, on the front, angled edge of a faceplate 2 is attached.
  • a locking head 3a formed at the front end of a locking shaft 3 projects through an opening in the faceplate 2.
  • the locking shaft 3 is mounted so as to be longitudinally displaceable via elongated holes 3b on guide pins 1a which are fastened to the lock plate 1.
  • the lock plate 1 is further provided with threaded bushings 1b.
  • the bolt consisting of bolt shaft 3 and bolt head 3a is actuated by a key S, which is shown in dashed lines in FIGS. 1 and 3 and is attached to a key pin 1c arranged on the lock plate 1.
  • This key S which is designed as a double-bit key in the exemplary embodiment, acts on locking tumblers 4, which are mounted on the lock plate 1 in a height-adjustable manner via elongated holes 4a on the same guide pins 1a as the locking shaft 3.
  • the locking tumblers 4 are each designed to interact with the key bit of the key S with a tumbler channel. In the area of this tumbler channel, two stop pins 1d are arranged on the lock plate 1, which prevent the key S from being rotated in the wrong direction of rotation.
  • Each locking tumbler 4 interacts via a coupling channel 4b with a coupling piece 5a of a changeover tumbler 5, which are mounted for height adjustment via elongated holes 5b on bearing pins 3c of the locking shaft 3.
  • Each changeover tumbler 5 interacts with teeth of a blocking tumbler 6 via a toothing formed on the front edge.
  • the locking tumblers 6 are guided in a height-adjustable manner by means of elongated holes 6a on guide pins 7a of a support plate 7 which is arranged below the locking shaft 3 between the locking shaft 3 and the lock plate 1.
  • 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 bearing mandrel 1e. These bearing pins 1e are arranged on the lock plate 1.
  • a tension spring 8 is arranged, which in the exemplary embodiment is designed as a helical spring and is suspended at one end on a spring mandrel 3e on the locking shaft 3 and at the other end on a spring mandrel 7b of the support plate 7.
  • the spring mandrel 7b of the support plate 7 extends through an elongated hole 3f in the locking shaft 3.
  • the support plate 7 is provided at its upper end, not shown in the drawing, with a coupling hook which interacts with a coupling hook of a changeover rod 9, also not shown.
  • This changeover rod 9 is guided in a vertically movable manner via elongated holes 9a on guide pins 1f of the lock plate 1 and is loaded by a return spring 9b.
  • the changeover rod 9 is provided with a driver 9c which has a bore 9d for attaching a tool.
  • a tool for example a pin
  • the faceplate 2 is provided with an actuation opening 2a.
  • this cover 10 consists of a cover plate with a cover part 10a extending parallel to the faceplate 2 and a guide part 10b extending at right angles thereto, that is to say parallel to the locking shaft 3a.
  • This guide part 10b of the cover 10 is movably supported by means of an elongated hole 10c on a guide pin 1g of the lock plate 1 parallel to the longitudinal extension of the face plate 2, so that the cover 10 either the cover position shown in FIGS. 1 and 2 or the one shown in FIGS. 3 and 4 can take the signed release position.
  • the cover 10 is transferred between these two end positions via a control mandrel 10d arranged on the guide part 10b, which engages in a control slot 11a which is formed in an extension 11 of the locking shaft 3.
  • This extension 11 is guided in a longitudinally movable manner by means of an elongated hole 11b on a further guide pin 1h of the lock plate 1.
  • the changeover rod 9 can thus be raised by means of a suitable tool inserted into the bore 9d of the driver 9c against the force of the retraction springs 9b in order to hold the support plate 7 with the locking tumblers 6 in the front end position, so that when the bolt is subsequently retracted, a Separation between the change tumblers 5 and the locking tumblers 6 defined on the bearing mandrel 1e takes place.
  • the actuation opening 2a for the changeover rod 9 is closed or opened, so that manipulations at the lock through the actuation opening 2a are excluded.
