  • the Bores 21 and 32 are approximately diagonally opposite to extension 18 of the key 3 attached in the middle part of the holder 5, while the Compression springs 19, 24 are adjacent to one another on one side of the extension 18 are located.
  • the projections 28 and 29 act together with recesses 33 the cover 6, which is attached diagonally opposite. Go berserk the holder 5 with the key 3 by 180 ° results in the possibility of tipping in the opposite direction.
  • the holder 5 can instead of the stub shaft 12 also corresponding Recesses or snap-in bearings to accommodate stub axles have connected to the cover 6 or the bottom plate 13 are to the holder 5 tiltable relative to the flap, the lid or the like. to arrange.
  • the bottom plate 13 can also through the flap, the lid or the like. to be replaced.
  • Such a radius actuator can with an additional Locking pin 34 for an electromagnet can be coupled as it in DE-U-87 16 018 and shown in Fig. 8.
  • the locking pin 34 has an extension 37 on the bottom, which has a Axle 38 received by holder 36 is pivotable in one plane the holder 36 is arranged.
