  • the object of the invention is to demonstrate a security device which, with a simple design, enables reliable locking of locking devices, for example window and / or door fittings or locks, against unauthorized actuation.
  • a safety device is designed according to claim 1.
  • a locking device is designed according to claim 26.
  • the safety device according to the invention is part of a window or door ski fitting, for. B. a window or door handle and / or part of a window or door lock and / or part of a lock or a lock for vehicle doors.
  • the activated safety device enables the actuation of a door and / or window lock or a window or door lock only with or after overcoming a predetermined force or a predetermined moment (actuating force).
  • This actuating force is adjustable or adjusted so that it can be used, for example, by children, but also at one Manipulation from the outside cannot easily be applied, ie the security device according to the invention is on the one hand a structurally simple but very effective child safety device, and on the other hand the security device according to the invention also significantly increases the security against break-ins in windows, doors, etc.
  • the securing device is preferably designed so that it can be deactivated and activated, for example by changing the actuating force or force characteristic li, which is required to actuate the respective lock fitting, lock, etc.
  • the invention can be integrated into existing industrial fittings, handles, locks, etc. in a simple and therefore cost-saving manner while maintaining existing construction principles.
  • This and the simple design and handling of the security unit according to the invention thus create the prerequisites for designing standard fittings with a reliable security device, in particular also with a perfect child lock, without extensive design changes and without impairing the proven function of standard fittings.
  • the invention offers the possibility of perfectly adjusting the safety device present on each door and / or window individually according to the respective requirements and circumstances, for example with regard to the age of the children, the respective setting of the actuating force then being adjusted via the setting of a spring force.

  • the points of attack and action for the adjustment of the actuating force are then provided at positions that are as freely accessible as possible.
  • the safety device according to the invention is designed so that an actuating force must be applied according to an adjustable force curve to actuate the respective locking device or the respective lock.
  • an adjustable force curve can also be dispensed with and at least one specially specified force or pressure point can be provided for this, which must be overcome for the actuation of the secured locking device or the secured lock and / or for deactivation of the securing device.
  • This pressure or force point can then be realized in a wide variety of ways, for example by means of locking elements, springs, etc.
  • Another advantage is that after activating the child lock, the child lock remains in the activated state and manipulation by children cannot easily take place, in contrast to conventional child locks on car doors, which are activated or deactivated by operating a lever. This lever can also be operated accidentally by a child, at least when the vehicle is stationary and the door is open.

  • the invention also has the advantage of a simple, constructive and thus reliably working construction.
  • the invention avoids components which are susceptible to faults and are easy to damage, particularly in the case of accidents, and in the process especially electrical and electronic components and is fully functional in almost every situation.
