Definitions

  • the invention relates to a roof window with an opening mechanism for the window sash.
  • the window sash is rotated via an arranged at the top of the window axis of rotation.
  • the window sash must be opened against gravity unlike normal windows. Therefore, the casements of these skylights are typically supported by hydraulic springs to facilitate opening and secure the casement in the open position.
  • this mechanism has a number of disadvantages. First, it is difficult to get to the outside of the sash to clean it. Second, the support mechanisms for the sash must be very robust and thus heavy and expensive to be designed to withstand even high wind speeds in the open state, as the open sash provides a high attack surface for the wind. This mechanism can not be used for any size roof windows, as correspondingly long supports for the roof window still have to be provided in the roof. This opening mechanism thus limits the size of skylights.
  • Lammellen that cover the roof window opening by a plurality of juxtaposed smaller window sash.
  • the individual window sashes can be opened by a rotation about an axis at the top.
  • the attack surface for wind is substantially reduced and the much smaller areas of the casement rear sides are much more accessible from the inside.
  • these skylights have the disadvantage that the view through the skylight window is disturbed by the window both in the closed and in the open window due to the large number of casements and their respective spars. Therefore, such louvre windows are mainly used in glass roofs, where the view in the area of the opening roof windows is not so important.
  • WO9119070 discloses a solution to this problem.
  • the skylight is divided into a fixed window glass and a mobile casement.
  • the mobile window sash is mounted in a rail that moves the sash out of the closed window level and then slides over the fixed window glass. This allows only half of the roof window to open. At the same time it is almost impossible to clean the outside of the fixed window glass.
  • the roof window has a window frame, a window sash and an opening mechanism.
  • the window frame is designed for installation in a building roof.
  • the opening mechanism for the Window sash can be brought into an open state and a closed state.
  • the opening mechanism is configured such that the window sash is movable from the closed state to the open state, wherein the sash is arranged in a closed state in a first plane and in the open state in a second plane parallel to the first plane.
  • the invention is also achieved by a roof with such a roof window.
  • the opening from a first level to a second level parallel thereto allows the skylight to be flush mounted and still bring the sash into an open position which, due to its parallelism to the closed position and thus to the roof surface, provides little wind contact area.
  • the sash can be designed more easily, since it is no longer exposed to such high forces.
  • the cleaning of the outer window surface is very easy, as it is directly adjacent to the window area with the window open.
  • the opening mechanism includes a first lever arm between a first side of the sash and a first side of the sash and at least one second lever between a second side of the sash and a second side of the sash, the lever arms being rotatable on the sash and sash are stored, wherein the opening mechanism is adapted to move the window sash by a rotation of the lever arms laterally out of the window frame.
  • This arrangement is particularly advantageous, since it is possible with this mechanism, by only a movement with only one degree of freedom, namely the rotation of at least one of the levers about the bearing axis, is possible to lift the sash out of the plane of the roof and parallel to the Place the lock on the side of the roof. This allows even flush with the roof built-in window a simple opening mechanism that releases the skylight and makes the outside of the window sash in the open state easily accessible.
  • the opening mechanism is configured such that the opening of the sash reached by the rotation of the lever arms is such that the sash releases more than 70% of the sash window opening area of the sash window in the open state when closed by the sash.
  • the opening mechanism is configured to move the window sash in a circular path from the closed state to the open state, wherein the window sash first moves away from the first plane during the opening operation and then approaches the first plane again.
  • the opening mechanism is configured to rotate the first lever arm and / or the second lever arm between the closed state and the open state by an angle of at least 140 °.
  • a rotation angle is possible, which allows to deposit the lever arms next to the window opening on a plane which corresponds approximately to the first level. If the roof window is mounted in the roof, this level corresponds to the roof surface.
  • the first in the direct line between the pivot points of the lever on a recess for the window frame which is formed so that in the open state of the opening mechanism, the recess of the first and third lever arm releases the window frame.
  • the laying down of the first lever arm on the roof surface absorbs the gravity acting on the opening mechanism, which reduces the wear of the opening mechanism.
  • the first lever arm has a short portion and a long portion, wherein the long portion is disposed in the open state generally parallel to the first plane and the short portion is formed in the open state, the long portion with the storage of first lever arm in the window frame to connect.
  • the length of the first lever arm and the second lever arm basically corresponds to half of a length of the first or second side of the window sash. So it is possible to move the window sash completely or at least almost completely out of the opening of the roof window.
  • the first lever arm is attached at a first end to the opening side end of the first side of the window frame and an opposite second end in the center of the first side of the sash
  • the second lever arm is connected to a first end in the window sash Attached to the middle of the second side of the window frame and at an opposite second end to the opposite side of the opening side of the second side of the window sash. So it is possible to move the window sash completely or at least almost completely out of the opening of the roof window.

  • a parallelogram guide of the window sash allows a simple and stable guidance of the sash on a circular path from a first plane to a second plane.
  • the first lever arm is arranged in the direction of the axis of rotation laterally offset from the third lever arm and / or the second lever arm in the direction of Rotary axis is arranged laterally offset from the fourth lever arm. Only by such an arrangement, it is possible to store the pivot point of the first lever arm in the middle of the first side of the sash and at the same time to store the third lever arm in the middle of the first side of the window frame.
  • the sash in the open state of the opening mechanism, lies on a longitudinal side of the first lever arm. This additionally stabilizes the window sash in the open state.

  • the spring means can be adapted to different roof pitches.
  • the casement is in the open state on the roof surface. This has the advantage that the opening mechanism is force-free in the open state. This reduces the wear of the opening mechanism.
  • the first side and the second side of the sash and / or the window frame are shorter than the other two sides of the sash and / or the window frame.
  • the sash opens in the direction of the shorter side, causing the sash to move less to the side, resulting in shorter lever arms, resulting in a lower force for rotating the lever arms.
  • the roof windows are usually longer in the direction of the inclination of the roof, it is particularly advantageous to open the roof window transversely to a slope of the roof. This has the additional advantage that the outside of the window sash is in the open state along the longitudinal side of the roof window next to the opening of the roof window.

Due to the flat support of the two lever arms 5.1 and 5.4, the weight of the sash 3 is evenly distributed on the roof covering 1.3 and not concentrated on one edge of the roof covering 1.3, which could damage the roofing 1.3.
  • the sash 3 in the open position need not be deposited on the roof surface, but may also be held in the open position by a motor, a fastener or a stop in the opening mechanism or by a spring.
  • the roof window 2 preferably has a motor 9 which is designed to rotate at least one of the four lever arms 5.1, 5.2, 5.3 and 5.4 about a bearing axis.
  • the first lever arm 5.1 and the fourth lever arm 5.4 are each driven by a motor 9.
  • the motor 9 drives the bearing axes of the first lever arm 5.1 and the fourth lever arm 5.4 in the window frame 4 in this embodiment.
  • the motor axis is parallel to the bearing axis of the lever arms 5.1 and 5.4 and is transmitted via a V-belt 10 on the bearing axis.
  • many other forms of the motor-driven drive a bearing axis of the lever arms 5.1, 5.2, 5.3 and 5.4 possible.
  • the roof window is 150 cm x 150 cm in size.
  • the lever arm is about 75 cm long and thus a very high force is needed to lift the window sash and then decelerate again when lowering. Therefore, it is advantageous to keep the sash 3 sideways to the sloping roof, i. perpendicular to the gradient of the roof pitch and in the roof level, to move.
  • already a part of the weight of the sash does not work in the opening and closing direction, but in the direction of the bearing axes of the lever arms 5.1, 5.2, 5.3 and 5.4.
  • the force of the motor could be assisted by spring means which, upon lifting the sash, provide a supporting force in the direction of rotation and when lowered cause a braking force in the direction of rotation.
  • spring means which, upon lifting the sash, provide a supporting force in the direction of rotation and when lowered cause a braking force in the direction of rotation.
  • This could be realized, for example, by converting the rotation of the bearing axes of the third lever arm 5.3 and the second lever arm 5.2 into a straight bar, e.g. over a rack.
  • the rod could be attached at one end to a first spring, e.g. a gas spring, abut, the rod detaches from a certain point of the first spring and pushes with the opposite end to a spring, which acts a force in the opposite direction. This could reduce the force on the engine.
