Furthermore, a push chain is also suitable for transmitting compressive forces in the longitudinal direction.
  • the push chain is therefore usually connected to the window frame and the window sash so that the sash can be opened by a pressure transmitted with the push chain compressive force, the push chain is loaded with the window open by a gravity of the sash so that the chain does not kink.
  • a moment acting on the push chain by the force of gravity of the window sash when the window is open preferably acts counter to the direction in which the push chain is flexible.
  • the chain is curved on the window frame in a direction in which the chain is pliable, and pulled into the window frame, after which the pusher chain is wound.
  • the push chain is connected to a longitudinal spar of the window frame.
  • the window frame usually has two parallel, approximately horizontally oriented transverse beams and two perpendicular to these arranged longitudinal beams.
  • an upper cross member normally forms an upper end of the window and another, lower cross member forms a lower end of the window.
  • the push chain can be wound in a longitudinal spar of the window frame, preferably in a plane lying perpendicular to a pivot axis about which the window wing is pivotable. This allows the push chain to be stowed in minimal space when the window is closed.
  • the window spar usually has a height, so that at least two layers of the push chain can be arranged one above the other in the window spar.
  • a guide is provided in the longitudinal spar, so that the push chain along a defined path in the longitudinal spar can be rewound.

  • the drive can then extend, for example, along a lower cross member of the window frame or in this transverse member so that the drive is likewise not visible and does not impair the appearance of the window in the interior.
  • a lower arrangement of the motor also results in a reduction of a view width, so that a visually appealing appearance is achieved.
  • the drive has a brake.
  • the window is held in an open state via the push chain after the window has been opened by means of the push chain and the drive.
  • the brake is released only when the drive is operated to open or close the window.
  • the drive has an electric motor, in particular a servomotor.
  • the electric motor via a transmission, in particular a planetary gear, connected to the push chain.

  • the drive can then be easily arranged on a part of the frame, for example, the lower cross member, such that it is not visible in an interior.
  • a sensor acting on the drive is provided, with which it can be determined whether an object, in particular a person, in an area of the window, in particular in an area through which the sash in a closing movement from an open Position is moved.
  • a sensor can be formed, for example, by one or more light barriers in the window frame, in particular infrared light barriers or a light barrier curtain, or comprise such devices.

  • injuries to persons are reliably prevented by the actively moving window sash, even in the case of large windows.
  • a blocking of the window sash during a closing movement by a person located in a movement region of the sash or an inhibition of the closing movement can be detected by a collision of the sash with a person in order to interrupt the movement if necessary and to avoid injury.
  • a risk of injury due to a lowering in case of failure of a power supply due to gravity window can be easily avoided by a brake with which the window sash in an open position, in which the sash is usually aligned approximately horizontally.
  • the drive can also be self-locking, for example with a worm gear.
  • the roof window can thus be used without risk of injury as a large, especially almost floor-to-ceiling windows in attic apartments with high inclination of up to 75 °, the window can be opened to a horizontal position so that it forms a roof and an area under the open Can be used as a roofed roof terrace.

  • the resistor may for example be arranged in a part of the window frame.
  • the push chain is guided in the window frame in a guide with a deflection.
  • the push chain is thus guided in the window frame, usually in a longitudinal spar, along the window frame or the longitudinal spar until the push chain is deflected over the deflection.
  • an orientation of the push chain corresponds to a direct connection between a position at which the push chain is connected to the window sash, and the deflection in the window frame.
  • this orientation is usually aligned perpendicular to a window surface or arranged in the window sash window when the push chain is connected at the same distance from an upper cross member with both the window frame and the sash.
  • the deflection is spring-loaded such that the push chain loads on a free length between the window frame and the sash against a direction is, in which the push chain is bend soft. It thus acts by the spring-loaded deflection a moment on the push chain opposite to the direction in which the push chain is pliable. This ensures that with the push chain in the area between the window frame and window sash a compressive force is transferable to reliably open the window and close or to keep in an open state.
