  • the spring-loaded pins 6 can be brought into alignment by magnets of different strengths, not shown, so that the pins 6 release the locking bolt 5 'and the padlock 4 can be opened.
  • the magnets of different strengths are attached to a coded magnetic plate 7, which can be placed on the coding side 8 of the padlock 4. After the magnetic unlocking, the padlock 4 is moved into the open position shown in dashed lines in FIG. 1, thus opening the key breakthrough 3 free.
  • a locking and guiding element 9 is firmly mounted on the security fitting 1, which is formed from two segment-like guiding disks 10, 11 and a circular guiding disk for the steel shackle 5, which is mounted between them.
  • the guide disks 10, 11 have on the underside a slightly inward V-shaped locking surface 13 for the correspondingly designed locking edge 14 of the padlock 4 and on the top curved curved guide surfaces 15, which are connected in between by latching surfaces 16 for the open position of the padlock 4 are. As shown in FIG.
  • the steel shackle 5 encloses the circular guide disk 12 in the closed position of the padlock 4, the slightly roof-shaped locking edge 14 of the body of the padlock 4 on the locking surfaces 13 of the two guide disks 10, 11 abuts.
  • pins 6 are locked in the locking bolt 5 and are under spring load, the padlock 4 is thus firmly locked and closes the opening of the key opening 3 inaccessible to unauthorized third parties.
  • the pins 6 are brought into alignment by the magnets of the magnetic plate 7 of different strengths, so that the locking bolt 5 'is released.
  • the body of the padlock 4 can thus be pulled down in the illustration according to FIG. 1 and then brought by means of the steel bracket 5 around the circular guide disk 12 into the open position shown in dashed lines in FIG. 1, in which the locking edge 14 on the lateral surfaces 16 of the guide disks 10, 11 is present.
  • the key opening 3 is thus freely accessible
