Definitions

  • the invention relates to a lock device, as they are usually used on containers and furniture, which are subject to higher-level management and relatively frequent user changes.
  • Locking lockers and storage cabinets (lockers), office furniture, switchgear and tool cabinets in schools, businesses and sports facilities is the most common application.
  • Lock devices of this type consist of a combination lock, which is usually designed as a combination lock and a secondary lock, which is usually designed as a master key to be operated cylinder lock.
  • the combination lock is intended for normal operation and assigned to the users of the cabinets. It usually has several numbered or lettered control wheels, by means of which an opening code is set.
  • the combination locks provided with the factory-preset opening code can be reprogrammed by the user to a personal opening code and changed again at any time.
  • the combination lock must always be in the open position or the currently valid opening code must be known. If the opening code is lost or forgotten, the combination lock can not be opened or the opening code can be changed.
  • the secondary lock is used for emergency opening and is assigned to the owner or administrator of the cabinets.
  • An emergency opening is required, for example, when a cabinet user has lost or forgotten his personal opening code, a user can no longer be found, or if control of the content must also take place without the presence of the user in order to prevent crime or to avoid danger.
  • the combination lock is usually simply bridged, so that with the master key each cabinet or lock device, even without knowledge of Opening codes, opens. Accordingly, the master key must be kept by the administrator.
  • lock devices such as those in the EP 2 419 586 and US 8,087,274 moreover, have a function for automatically discarding the opening code during the opening movement of the lock device. This function is intended to ensure that the set and therefore visible opening code is automatically blurred after opening the lock device and does not remain visible for an unnecessarily long time. When blurring so only the adjusting wheels are rotated out of the opening code out in a specific predetermined position. The valid opening code is retained.
  • the code discovery represents a considerable security gap because the supposedly secure personal opening codes can basically be read out by any unauthorized person who, even if only for a short time, obtains the master key.
  • the particular risk of this is that the reading of the personal code remains completely unnoticed when the master key is put back in place. Thieves could gain regular access in this way.
  • program the described Codefinding function is even more critical especially as most users are probably unaware that this code discovery function exists.
  • the other major drawback is the extra time required to find the lost opening code to reset a lock to its delivery condition.
  • the compulsion to code can mean a significant effort for the administrator, because vacant cabinets or locks are usually left by the users with their personally set codes.
  • the scanning of the individual adjusting wheels with an additional tool is very time consuming.
  • the present invention seeks to provide a lock device that is reset in factory settings and in the retrieval of a lost opening code is neither possible nor necessary and thus provides security against reading the personal opening code and about
  • a quick and comfortable management of the lock device ensures when users change frequently.
  • the object is achieved in that the resetting of the combination lock automatically takes place in a state with predetermined opening code, when the secondary lock is actuated and during the opening rotation of the lock device by simultaneous actuation of an actuating element, the clutch discs are disengaged from the setting wheels.
  • the adjusting wheels of the combination lock on coaxially arranged clutch discs, which can be rotatably engaged or disengaged in different angular positions with the setting wheels, and having pockets on an outer peripheral surface into which the sensing elements of a sensing part can fall.
  • each adjusting elements formed by means of which the adjusting wheels and clutch discs can be rotated by a setting in a predetermined angular position when adjusting sections of an adjustment act on the control elements, wherein the predetermined angular position preferably corresponds to the factory preset opening code.
  • the Stellrad readilye- and clutch plate side adjusting elements are advantageously designed so that they are spirally tapering on the axis of rotation curve portions which, when acted on by adjustment of the actuated adjusting member in the direction of the axis of rotation, the adjusting or coupling discs rotate in a predetermined angular position.
  • first Einstellabroughe are formed, which are associated with the control elements of the adjusting wheels and second adjusting sections associated with the control elements of the clutch discs are, wherein the first adjusting portions are arranged so that they act on each actuation of the adjusting member on the adjusting elements of the adjusting wheels and the second adjusting portions are arranged so that they act on the adjusting elements of the clutch discs only when the clutch discs in one with the Adjusting wheels are disengaged position.
  • the adjusting member is operated every opening rotation of the lock apparatus.
  • a coupled with the setting wheels position of the clutch discs only the adjusting wheels are rotated according to their predetermined position accordingly.
  • the rotatably engaged clutch plates are thereby, without changing their relative position to the setting wheel, taken away, so that the set opening code is maintained and the blurring of the displayed opening code is guaranteed.
