DESCRIPTION:
BRIEF SUMMARY
The invention relates to a lock system in a door, wall, chest, safe, cupboard or the like, which is covered by an outer plate, a locking bolt, gripper or the like, coupled to a main lever rotating about a pivot bearing, cooperating with a holding plate, a bolt or the like.
The protective function in the private and business sector is first and foremost the individual's own responsibility and therefore self-protection. Daily break-ins are increasing alarmingly despite the best-constructed and secured house entrance doors, alarm systems or the like.
A series of cylinder locks and bolt locks, in which relatively stringent safety standards are taken into account, are known as safeguards in this respect. In all these locks, however, their position is visible from outside, specifically, as a rule, as a result of the arrangement of corresponding latches, keyholes or the like. The intruder immediately knows, here, where he has to start in order to break the corresponding lock.
Alarm systems involve a high outlay and likewise do not unreservedly afford sufficient security.
The object on which the present invention is based is substantially to improve the security of a lock system.
This object is achieved in that the rotation of the main lever is dependent on the movement of a magnetic block attached to the outer plate, the main lever having at least one bore for receiving at least one retaining pin, to which a further magnetic block attached to the outer plate is assigned for the purpose of release by pulling out of the bore.
This is an invisible lock system, the position of which cannot be seen from outside. This lock system can be located at any point in a door leaf, but the door leaf is completely smooth, as seen from outside. It thus becomes extremely difficult for the intruder to determine the position of the lock system. The same is also true of the arrangement of this lock system, for example in the wall of a chest, a corresponding lid being held in the closed position by the locking system. The list of sectors or the furniture for which this lock system can be employed is only illustrative, and further possible uses also come within the scope of the invention.
The initiation of an opening or a closing operation is obtained by attaching magnetic blocks to the outer plate, these magnetic blocks performing separate functions as magnetic keys. They interact with the inner magnetic blocks.
The inner magnetic block which holds the retaining pins can be designated as the technical core of the entire system. The retaining pins are so mounted in this magnetic block that, when the outer magnetic block is attached to the outer plate, they are pulled out of the bores of the main lever. This takes place, for example, by connecting the retaining pin to a pull magnet. The return of the retaining pin into its closing position then takes place once again with the aid of a corresponding compression spring.
However, a possibility of indirect movement for the retaining pin is also possible, if the latter is connected to a push magnet via a rocker lever. The rocker lever has a fulcrum approximately centrally, so that, when the magnetic block is attached, the retaining pin is pulled out of the corresponding bore as a result of the repulsion of the push magnet.
Moreover, these bores are preferably to be arranged on segments of an arc of a circle above the pivot bearing of the main lever. The retaining pins are then also located on these arcs of a circle, so that they can engage into the corresponding bores after a specific rotation of the main lever.
In a very simple exemplary embodiment, a single retaining pin is sufficient. Even for the retaining pin there is a plurality of possible arrangements in the magnetic block. But since a lock system having a large number of locking permutations is to be produced, a multiplicity of retaining pins is provided in the magnetic block. It is possible, at the same time, both to vary the position of the retaining pins relative to one another and to alternate them with push and pull magnets or
