  • the invention is located in the field of locking systems, in particular the mechatronic locking systems, for example for doors.
  • the invention relates to a housing, which has at least one movable element and a closure device, by means of which the movable element can be locked, and a tool and a method with which the locking of the movable element can be canceled.
  • An illustrative example is the battery-containing housing, which is attachable to a door and houses the essential parts of a mechatronic locking system, a coupling mechanism and elements for authentication, data transmission and drive.

  • the mechanism of the locking comprises the engagement of the locking pin described below in detail in the latching device.
  • the specific position is in particular to a position in which the housing is closed by the movable member or parts thereof, that is, in which can not be accessed directly through the opening to the interior.

  • the resistance may be so great that a force that is not mechanically applied to the closure device is not sufficient to move the locking pin from the first to the second position.
  • a force generated by magnets and / or by a movement of the closure device can not be sufficient for applying the said force.
  • a second force is to be applied to the closure device, which deforms the second elastic element to such an extent the additional resistance is massively reduced or even eliminated.
