Definitions

  • the invention relates to a roof window according to the preamble of claim 1.
  • the invention has for its object to prevent the passage of sun rays in a blocking time between two times of a reference day with a window of predetermined inclination and orientation, but to impair the light transmission in the rest as little as possible.
  • the blocking area of the prismatic plate should not be larger than is necessary in view of the complete suppression of the sun in the blocking area of the reference day.
  • the inventive solution to this problem is characterized in claim 1. It is based on the finding that the fade-out curve of such a window in a tanning diagram runs in the same way as the path curves of the sun, that the central axis of the fade-out curve swings relative to the central axis of the sun's path by a suitable choice of the axis angle of the prism poles, and that the fade-out curve also moves through appropriate choice of the base angle of the prism rods can move very close to the trajectory; this enables the area between the blanking curve and the trajectory to be minimized so that the window allows maximum daylight to pass through.
  • Such a prismatic plate allows the high zenith light, which occurs above a certain critical angle, to enter the room and reflects the light incident at this critical angle, in particular direct sunlight.
  • this statement only applies strictly to a cross-sectional plane perpendicular to the surface and to the longitudinal axis of the prismatic plate; There are no clues about their fading characteristics across and a specific assignment to the sun's path - especially with an inclined window area.
  • a blind for horizontal roof windows with equidistant slats is also known, which are arranged perpendicular to a vertical plane running in a north-south direction; this also applies if the window is not in the east-west direction, so that the slats then run at an acute angle to the horizontal lower edge of the window.
  • Such a blind fades out the sun and at the same time lets the zenith light through.
  • this passage area does not reach up to 180 ° above the limit angle.Furthermore, this solution can only be used for flat roof windows and for south-facing vertical windows, since only in these cases can the louvres be oriented parallel to the east-west direction.
  • a roof window with the window surface F is shown schematically, this window surface being inclined by the angle ⁇ with respect to the horizontal plane H and oriented in the stated manner towards south-east.
  • the window surface F is filled with a prism plate, which has a flat base surface PO on the outside and prism rods P which adjoin one another on the inside without gaps, with the cathetus surfaces P1 and P2 running at right angles to one another (cf. the enlarged sectional view in the extension of the section line L in FIG. 1).
  • the longitudinal axes of the prism bars P run perpendicular to a section line L and thus include an axis angle y - measured in the window plane F - with the horizontal boundary edge K.
  • the intersection line L is given by the intersection of the window surface F with that on its perpendicular reference plane E, in which the greatest elevation angle of the sun occurs on the reference day and within the restricted area, measured in the reference plane E against the intersection line L.
  • the path curve the sun on the reference day is designated by B in FIG. 1.
  • One of the catheter surfaces, namely P2, of the prism rods P is mirrored on the inside.
  • the prism rods are arranged in such a way that the tip of the largest height angle ⁇ max indicates the mirrored catheter surface P2.
  • FIG. 2 shows qualitatively the course of the sun path B ': it gives the respective elevation angle y of a sun ray D measured in the reference plane perpendicular to the window plane E, depending on the angle X of the intersection line L of this reference plane with the window plane measured against the horizontal edge K (correspondingly the definitions for the reference plane E in Fig. 1).
  • the largest elevation angle ⁇ max and the angle X max of the associated reference plane in which this largest elevation angle occurs can be read from FIG. 2.
  • the optimal axis angle y of the prism rods is thus already determined.
  • the blanking curve A must now run - at least in the desired restricted area - above the rail curve B ': the entire area and Below this blanking curve A is the blocking area in which the prismatic plate does not let light through.
  • the part of this restricted area lying above the trajectory B 'of the reference day should be as small as possible so that as much daylight as possible is let through.
  • the base angle a of the prism rods For this purpose, the masking curves of prism rods with a different base angle are recorded according to FIG. 3 and then compared with the path curve to be masked out, the family of curves according to FIG. 3 being rotated so that the symmetry line M 'with the line of symmetry M of the trajectory B' in Fig.
