  • the closing elements In order to lock the closing elements in the closed position so that they cannot be opened, the closing elements mostly have one or more locking devices.
  • These Ver locking devices usually have a locking element which is rotatable to and fro about an actuating axis between a locking position and an unlocking position.
  • the locking elements In the locking position, the locking elements engage behind or in a fixed frame of the locking element, for example in the manner of a sash tongue, and thus fix the locking element with respect to the immovable frame.

  • the invention aims to provide a locking device with which such a risk is reduced.
  • the configuration that the locking element for emergency unlocking can be pivoted about an emergency unlocking axis from the locking position into an emergency unlocking position and the emergency unlocking axis and the actuating axis are arranged at an angle to one another results in the advantage that the locking element, even if a rotary movement about the actuating axis is not possible is, can be pivoted by a movement around the emergency unlocking axis into a position in which the locking element can be opened.
  • the angled arrangement offers the advantage that the locking element can be automatically transferred into the emergency unlocking position by applying a force, in particular a pressure force, to the closing element. It is therefore not necessary to actively pivot the locking element into the emergency unlocking position, but rather the locking element can be opened intuitively, for example in an emergency situation.
  • the emergency release axis and the actuation axis have one Angle between 45 and 135 degrees, preferably between 70 and 110 degrees, particularly preferably between 80 and 100 degrees, very particularly preferably between 85 and 105 and in particular of 90 degrees.
  • the actuation axis and the Notentrie gelungsachse are perpendicular to each other, the locking element can thus be most easily transferred to the emergency unlocking position.
  • the actuation axis and the emergency unlocking axis can intersect, but they can also be arranged skewed to one another. Even if these are arranged skewed to one another, the angles given above can be defined. What is meant is the cutting angle when the axes are shifted in parallel.

  • the locking element must be swiveled 90 degrees out of the locked position until it reaches the unlocked position.
  • the locking device has an emergency actuation element.
  • This can be coupled to the locking element in an actuating position in such a way that the locking element can be rotated back and forth between the locking position and the unlocking position via the emergency actuation element about the actuation axis.
  • the emergency actuation element can be arranged on the side of the closing element opposite the actuation element.
  • the emergency actuation element is arranged on the inside of the closing element.
  • the emergency actuation element can have a handling area which can be configured, for example, as a lever, latch or knob and via which the emergency actuation element can be moved manually. If rotation of the locking element about the actuation axis is not prevented, the locking element can be rotated via the Notbe actuating element in a very analogous manner to actuation by the actuating element. In the actuating position with the locking element, the not actuating element can in particular also be coupled to the actuating element. When the actuating element or the emergency actuating element is rotated about the actuating axis, the corresponding other element can also rotate around the actuating axis. If a movement of the locking element around the actuation axis is prevented, a movement of the emergency actuation element and the actuation element around the actuation axis is also prevented.

  • this option should not be misused for normal opening of the closing element, since otherwise it cannot be guaranteed that the closing element can be securely locked and protected against unauthorized opening. If the emergency actuation element is in the actuation position, the closing element can therefore only be opened when the locking element has been in the unlocked position.
  • the emergency actuation element can advantageously only be reached and actuated from the inside of the locking element, it is therefore not possible to remove the coupling of the emergency actuation element and locking element from the outside in order to pivot the locking element about the emergency unlocking axis and to open the locking element.
