  • the blocking element blocking only starts by actuation of the microswitch (by the slider) when the blocking element or the sliding stop-forming part of the blocking element has been at least partially slipped over or pushed out of the sliding path by the slider
  • the guide rail is thus first the blocking element or the part of the blocking element which carries the slider stop, and only then the switching element which lies behind the blocking element in the opening direction rests on the blocking element or it has already happened this at least partially in the opening direction.
  • the slider in the door opening direction preferably pushes the sliding stop out of its sliding path.
  • This embodiment ensures that a triggering of the blocking element blockage by an actuation of the switching element takes place only when the door is opened at least so far that the slider in the guide rail has at least partially already passed the locking unit in the opening direction or rests on the sliding stop.
  • the distance between the blocking element and the switching element in the context of the invention is of course variable.

  • the blocking element blocking according to the invention is preferably designed in such a way that the electromagnet must be energized to activate it. With regard to the activation of blocking element blocking, a quiescent current variant is thus preferably present. This is especially advantageous when the locking unit is used in safety-relevant areas, such as in the field of fire doors, etc.
  • switching elements are in principle all those elements of the prior art into consideration, which are designed such that they can be actuated by the slider, and which can trigger the activation of blocking element blocking on actuation.
  • the switching element is for this purpose, for example, an actuating element projecting into the sliding path of the slider (thus comparable with the slider stop), in particular in the form of a micromotor. Switch, which changed in its position by sliding over the slider, in particular folded and / or pushed into the locking unit, is.

  • internal parts of the locking element can be arranged quite well next to internal parts of the switching element.

As long as the blocking element or at least the slider stop of the blocking element is thus in the release position, that is, for example, pressed into the locking unit, the blocking element blocking is thus indeed activated upon actuation of the switching element. However, this does not detect the blocking element in this release position.
  • the locking element blocking is further formed in such a way that the determination of the blocking element in the stop position also takes place when, starting from the release position, the blocking element arrives at already activated blocking element blocking in the stop position.
  • the essential task of blocking element blocking is that it can selectively fix or release the blocking element in its stop position.
  • a locking unit the locking lever has a blocking role, which at least partially engages behind the blocking element with activated blocking element blocking, has proven to be particularly favorable.

To release the blocking element thus only relatively small adjustment paths are required.
  • a blocking role is characterized by a particularly high functional reliability, since jamming etc. of the locking mechanism is particularly rare here.
  • the electromagnet and the switching element are arranged in a series circuit. In this way, the condition can be obtained particularly easily and thus preferably that an actuation of the switching element for activating the blocking element blocking respectively the electromagnet is required.
  • the blocking element in principle, it is possible for the blocking element to be arranged on the arresting unit such that it can be moved in a linear movement, typically perpendicular to the sliding movement of the slider guided in the slide rail and in the direction of the locking unit, between the stop position and the release position is to hold or release the slider.

  • the actuating force is considerably greater than is necessary for merely holding the slider in the stop position (contrary to the door closing force exerted by the door closer on the slider).
  • An advantage of this embodiment is that for manually pushing the door with the locking device according to the invention, the armature does not have to be torn out of the energized coil (if the blocking element blocking comprises an electromagnet) (which usually results in a comparatively high level of noise). Rather, the override device according to the invention makes it possible to avoid the sliding stop from the sliding path of the slider in the door closing direction when the activated locking unit is pushed over in the door closing direction without the position of the (energized) blocking element blocking being influenced.

By the actuation of the switching element 11 of the electromagnet 19 is indeed energized. However, the locking lever 23 can not extend into its blocking element 10 'blocking position, since the blocking roller 24 abuts against the outer wall of the locking element 10' and in this way can not pivot into a locking element 10 'engaging behind position.
