  • the locking device according to the invention is used in automatic door or gate systems which comprise single-leaf or multi-leaf sliding doors or sliding gates or have multi-leaf folding sliding doors or folding sliding gates, or which are equipped with multi-leaf folding doors or folding leaf gates or in which at least one revolving revolving door is present , intended.
  • locking devices in particular automatic locking devices, are already present, which act on the one or more leaves only at the top in the area of the leaf guide.
  • a carriage is locked, on which a wing of the sliding door is suspended, with respect to a running rail, along which the carriage can be displaced when the sliding wing is opened and closed.
  • Such locking devices are relatively far from the actual door wing. Sliding sashes locked in this way can therefore be swung apart with greater effort in the direction of movement of the sliding sash in their lower area, in the case of multi-leaf sliding doors compared to another door leaf or in the case of a single-leaf sliding door opposite a fixed door frame.
  • the at least one or more wings of the door or gate system which are movable between a passage opening and a passage closing position, are not only closed in the upper area but also in the area of the floor with a fixed one Part of the door or the gate and / or locked with another adjacent wing.

  • the positive connection of the locking elements acts in all directions.
  • the operator for example of a sliding door or sliding gate system, can lock it securely in the closed state only by actuating a switch.
  • the locking takes place automatically in the closed state of the sliding door or sliding gate system. Additional manual operations, such as operating a door lock in the floor area or mechanically locking crown bars, are no longer required.
  • a preferred embodiment provides only a single drive unit for both the upper and the lower locking elements. These are coupled to one another with a coupling means.
  • the coupling means can be a mechanical coupling means which comprises an element, for example a rod, which extends parallel to a vertical profile of a movable door leaf, essentially from an upper leaf edge to a lower leaf edge. It is envisaged to arrange the mechanical coupling means so as to be invisible in a cavity of said vertical profile.
  • Another embodiment provides a drive unit for the upper locking elements and for the lower locking elements.
