Definitions

  • the invention relates to a magnetic locking device for locking suitcases or similar containers, doors, lockers, drawers or the like.
  • a magnetic code lock With a magnetic code lock, the magnetic wheels can be brought into a position in which a locking rod of the magnetic code Lock is adjustable from its blocking to its release position and vice versa, and a magnetic key that can be inserted into the magnetic code lock and by means of which the magnetic wheels can be brought into the position in which the locking bar of the magnetic code lock between them Blocking and its release position is adjustable.
  • the manufacturer normally enters a code or magnetic code on the magnetic key, to which the magnetic code lock is set.
  • the invention has for its object the locking security to increase such magnetic locking devices and to simplify the manufacture of such magnetic locking devices in that the same magnetic code locks can always be produced.
  • the magnetic key has adjusting disks, each of which between positions in which the magnetic code of the magnetic code lock on the magnetic key is not set and the position in which the magnetic code of the magnetic Code lock on the magnetic key is set, is adjustable.
  • the end user can then enter personal data as a magnetic code, which is then set by inserting the magnetic key into the magnetic code lock.
  • the magnetic key has a plastic housing in which the adjusting disks are rotatably mounted.
  • a simple design solution for the magnetic key and for the magnetic code lock can be achieved if a magnet is held eccentrically in each magnetic wheel of the magnetic code lock and in each adjusting disc of the magnetic key.
  • Maintaining the unlocking of the locking bar of the magnetic code lock when the magnetic key is located outside the magnetic code lock can be achieved if the magnetic key is in an "open" position which sets the magnetic code on the magnetic wheels of the magnetic code lock - and in one the magnetic wheels of the magnet Code lock from the magnetic code-adjusting "To" direction can be inserted into a key slot of the magnetic code lock and the magnetic key has a recess that a portion of the magnetic key lock in the key slot of the magnetic code lock Key slot is assigned, in which an actuating section of a locking spring is arranged.
  • an operating state of the magnetic code lock can be achieved in which the locking rod remains in its release position, although the magnetic key is removed from the key slot of the magnetic code lock. This is particularly useful if the case or the like.
  • Container is in a private sphere for a longer period of time, in which it would be annoying if the magnetic key was required each time to open the case or the container.
  • a comparatively simple initial or re-coding of the magnetic locking device can be achieved if a sliding plate is provided which is arranged in the magnetic code lock and the like when the case is open. can be actuated and by means of which the engagement between the magnetic wheels and clutch disks of the magnetic code lock can be canceled in order to readjust the magnetic code, the readjustment of the magnetic code by inserting the magnetic key set with the new magnetic code into "open" - Direction is accomplished.
  • two magnetic disks are assigned to each magnetic wheel of the magnetic code lock, both of which can be non-rotatably coupled to the magnetic wheel and are arranged axially displaceably on the journal between two positions with the magnetic wheel, the one of the two positions being the first clutch disks of the magnetic wheels and in the other of the two positions the second clutch disks of the magnetic wheels are arranged in the plane in which they interact with the locking rod.
  • This makes it possible for one and the same Locked to provide two different key secrets, the first of which is set on the first clutch plates and the second on the second clutch plates.
  • Different people can thus have different types of magnetic keys, although both magnetic keys are still able to bring the magnetic locking device into an open position.
  • a magnetic key can be a so-called general key that can be used on a large number of such magnetic locking devices.
  • the setting of the different key secrets can be realized in a particularly simple manner if the magnets on the magnetic key side are arranged in one of the two magnetic keys in such a way that they attract the lock-side magnets, and in the other magnetic key, the magnets of which are arranged in such a way that they repel lock-side magnets.
  • the property of magnets to attract each other, as well as the further property of repelling each other when opposite poles face each other, are used to set the key secret.
  • a magnetic code lock 1 shown in FIGS. 1 and 2 which forms a magnetic locking device with a magnetic key 2 described later with reference to FIGS. 17 to 26, is in a suitable position, e.g. attached centrally on a narrow long side of a case, not shown in the figures.
  • the magnetic code lock 1 has a locking rod 3, which projects on both sides via a housing 4 of the magnetic code lock 1. Outside the housing 4 of the magnetic code lock 1, two release buttons 5 are arranged for a case lock, not shown in the figures.
