  • the grooves 26 and 27 serve as storage of the aforementioned projections 20, which are on the outside of the Locking bolt 11 are formed.
  • the locking bolt 11 preferably has two oppositely arranged pin-like projections 20. Are they This corresponds to projections 20 in opposing deep grooves 26 the locking position of the locking bolt 11. However, the Projections 20 in opposite, less deep grooves 27 is the Locking bolt from its locked position to an unlocked position emotional.
  • the individual teeth of the counter edge 18 are offset from the Jagged edge 19 arranged. Between the individual teeth of the counter edge 18 Grooves 28 can also be formed, which act as a stop surface for the projections 20 serve the locking bolt 11.
  • the projections 20 of the locking bolt 11 are in opposite deep grooves 26. Is now used to unlock the locking bolt 11 a voltage pulse is applied to the electromagnet or to the coil 10, the Anchor 50 with the locking bolt 11 coupled to it pulled upwards, so that the projections 20 on the perpendicularly opposite to the corresponding groove 26 descending flank of the counter edge 18 (seen from the part 16) nudge. Then the projections 20 along this falling edge of the Counter edge 18 guided so that the projections 20 as shown in FIG. 9 to the right in one corresponding groove 26 adjacent groove 28 of the opposite edge 18 are conveyed. In this Groove 28, the corresponding projection 20 remains held even if the Coil 10 current should be supplied.
  • the projections 20 migrate with the locking bolt 11 alternately applying voltage pulses to the electromagnet arrangement accordingly clockwise through the individual grooves 26 and 27 of the lower edge 19th
  • the projections 20 are placed in the deep groove 26, so that thereby the locking bolt 11 is held at the same time.
  • the locking bolt 11 has a thickening 12 on its underside which, as shown in Fig. 5, in the locked position of the Locking bolt 11 is guided in a constriction 43 of the door fitting housing.
  • This thickening 12 is shaped such that it then only narrows the 43rd can happen if the projections 20 are in deep grooves 26, because only in this If the thickening 12 with the locking bolt 11 is aligned with the constriction 43 the housing is rotated.
  • the projections are in less deep grooves 27, is synonymous with the fact that the thickening 12 of the locking bolt 11 is not is aligned with the constriction 43 and thus does not pass the constriction 43 can and rests on the upper edge of the constriction 43.
  • the amount of Grooves 27 are dimensioned such that in the unlocked position Locking bolt 11 is held in the grooves 27 solely via the projections 20, without to rest with its thickening 12 on the upper edge of the constriction 43.
  • the holding mechanism described above with the crown-like parts 15 and 16 leads thus the function that after movement of the locking bolt 11 from its Locking position in the unlocking position of the locking bolt in the corresponding grooves 27 in the unlocked position even after a subsequent one
  • the control circuit 24 shown in FIG. 2 does not occur Adjustment signal remains held. Only when a new adjustment signal occurs through the Control circuit 24 or when a new voltage pulse is applied to the coil 10 Electromagnetic arrangement, the locking bolt 11 is back in the Locked position transferred. This way it becomes a relatively simple one Holding mechanism for the locking bolt 11 provided to by means of the Control circuit 24 timed the locking mechanism of the to release the door fitting according to the invention for a certain opening time.
  • this Control circuit 24 After Detection of a user's access authorization sets the purpose for this Control circuit 24 a first voltage pulse to the coil 10 of the Electromagnet arrangement, whereby the locking bolt 11 of the in Fig. 5th locking position shown in the unlocking position and the projections 20 in higher lying grooves 27 are transferred. After a predetermined The control circuit 24 applies a renewed voltage pulse to the coil 10 during the opening time on, as a result of the holding mechanism described above, the projections 20 of high grooves 27 are converted into deep grooves 26 and the locking bolt 11 returns to the locked position. Only during the previously defined Opening time is the locking mechanism consisting of those previously described Disks 29 and 36 and the rotary shaft 8 released, so that the locking mechanism the door 2 from the outside of the door only during this opening time the in Fig. 1st external turning handle 5 shown can be actuated.
