Definitions

  • the invention relates to a lock and Key existing locking device, in which the key with coding that can be inserted into a channel is equipped to classify tumblers a tumbler carrier movably arranged in the castle, its mobility by classifying the tumblers is to be released, the tumblers in different positioned pockets of the tumbler carrier are arranged displaceable.
  • a locking device of the type in question is known for example from US Pat. No. 3,234,768, wherein the tumbler carrier as rotatable in a cylinder housing arranged cylinder core is designed. In this are in the longitudinal direction of the cylinder core seen, tumblers arranged in a row in the form of core pins, which with spring-loaded housing pins work together. Between the end of the key neighboring tumbler and the housing pin is a temporary guard locking provided in the form of a ball, so that the lock, for example, in the construction phase a temporary key can be operated. Crossing for the pin hole of the first tumbler is in the housing a cross hole is provided.
  • the object of the invention is based on the object a locking device of the type in question to design in a technically simple manner that a change in the closure means normal designed tumblers is enabled.
  • This task is solved with a locking device with the features of claim 1, being based on it is connected to at least one pocket stands with an additional clearance of the built in the castle Tumbler carrier for optional assembly of the Bag with a tumbler.
  • the locking device can be operated using a temporary key are operated by a basic assembly of those in the tumbler Tumblers is classified according to regulations. When using the locking device in a locking system or residential complex can then all locking devices closed by a temporary key will. After completion of the construction phase, there is scope for additional space a transfer of the guard locking into the Bag according to a predetermined locking plan. It can several pockets a common space for addition be assigned. But it is also possible to have several Bags with one additional space each correspond allow. After changing the coding is temporary Key no longer suitable, the locking device to operate, because all tumblers by this can no longer be classified. If applicable it is also possible to close a locking device to change later, by removing corresponding tumblers about the additional space. Then the bags can be equipped either the assembly differ from the original to lock out the previously used key.
  • the channel-like additional space is open to the outside. Multiple tumblers can be used to change the locking code one after the other in the channel-like additional space and from there to the relevant lock plan Insert bags. Then the The locking device is no longer used to operate.
  • the Mouth opening of the channel-like additional space can be closed by a filler.
  • the filler After assembly the corresponding, to the channel-like additional space the filler is to be used towards open pockets. Free space and filler are thus one on top of the other voted that the latter was not removed without authorization can be. It proves to be favorable that the filler in the channel-like additional space can be moved while closing the pockets. Consequently the filler fulfills a double function: on the one hand it closes the mouth opening and on the other hand nor the pockets so that the tumblers do not come out of the Hike bags into the channel-like additional space can.
  • the number of possible closings can be reduced increase, several adjacent channel-like additional free spaces to be provided in the tumbler.
  • Feeding advantages result from that adjacent channel-like additional spaces are parallel run to each other and to the same side are open.
  • the idea of the invention can also be applied to such Realize locking devices that one or more juxtaposed, of different Keys have movable tumbler carriers.
  • a locking device in master key systems can therefore not be based on the subordinate Key the parent's lock encoding Determine the key.
  • the measure lends itself to that only one of the tumblers with one or more Complementary freedom is equipped.
  • the key Preferably becomes the key to be operated by the parent Tumbler carrier with one or more channel-like Complementary freedom.
  • the locking device can be operated with both keys will.
  • the tumbler carrier which does not have any additional freedom emotional. If the other key is used, so he shifts the one that has the additional freedom Tumbler.
  • the latter can be equipped with basic equipment to be provided with tumblers.
  • the final Closure is then completed by the addition of the free space outgoing pockets. Subsequently an adapted key must be used.
  • the tumblers it is possible for the tumblers to be made of magnetic pins exist and the area magnetized Key overlap to guard locking device can be inserted. Due to the area magnetized The magnetic pins are key from the magnetic fields of the key so that it has holes leave a locking plate and accordingly the relocation of the tumbler designed as a slide allow using the key. Part of the to be classified Magnetic pins are in the from outgoing pockets.
  • the security value of the locking device is thereby can be increased so that the mouth opening only in the release position shifted tumbler is accessible.
  • the number of tumblers that represent basic equipment must be placed in the tumbler carrier before the tumblers be classified by the key so that the tumbler is relocatable. Only in this Position, the mouth opening is released for moving in the corresponding tumbler pins.
  • the channel-like additional space from the mouth opening area is curved.
  • the ones to be brought in Tumbler pens can then be used using a appropriate insertion tool, so to speak, around the corner to be directed to the appropriate pockets afterwards immerse yourself.
  • the supplementary freedom as the key insertion direction triangular chamber is designed with in the direction the bag sloping base. As an insertion element then the key serves. This transports the guard locking up to the area of the triangular Chamber supplementary clearance. The chamber then allows the entry of the guard locking into the pocket.
  • the aforementioned design is optimized by in the key insertion direction Chamber-free spaces arranged one behind the other different widths so that the chamber width to the key insertion end of the castle decreases. This ensures that tumblers of a certain width can only be adapted to the width Bags can reach.
  • the method for coding a lock according to claim 1 is characterized in that from the additional space a magnetically coded pin down to the Bag related to the additional space is shifted.
  • the tumbler can do this are already in the additional space beforehand.
  • Relocation of the tumbler to the corresponding one Bag changes the closure along with it of the castle.
  • the guard locking using a tool in the additional space to transport from where the tumbler is transferred into the appropriate bag.
  • the locking device provided as a whole with the number 1 has one on a door 2 - for example a hotel room door - fixed lock 3.
  • the latter has a lock case 4 arranged on the outside of the door rectangular floor plan, which on its one End a freely rotating external turning handle 5 is stored. With their help can only be provided if a suitable one is inserted Key card and shifted tumbler one Trap 6 to be withdrawn.
  • One on the inside the door 2 arranged inside turning handle 7 is against it coupled directly to the trap 6, so that from this Side of the door 2 can always be opened.
