Definitions

  • the invention relates to a roof window according to the preamble of claim 1.
  • the invention is based on the object of preventing the passage of sun rays in a blocked area of a reference day for a window having a predetermined inclination and orientation, without impairing the light transmittance outside the blocked area.
  • the restricted area should not be larger than is necessary in view of the complete dazzle of the sun in the blocked area of the reference day.
  • the longest day of the year with the highest possible position of the sun is chosen as the reference day for the conditions for leaving; the sun is completely hidden throughout the year.
  • the invention is illustrated by the figures; show it
  • FIG. 1 schematically shows a window with the parameters
  • FIG. 2 shows a tanning diagram with trajectory curve B 'and glare curve A
  • FIG. 1 shows a skylight with the window surface F schematically, this window surface being inclined by the angle ⁇ relative to the horizontal plane H and oriented in the manner indicated towards south-east.
  • the window surface F is filled by 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 catheter surfaces P1 and P2 running at right angles to one another (see 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 - measured in the window plane F - pit of the horizontal boundary edge K.
  • the section line L is given by the section, 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 section line L.
  • the trajectory of the sun on the reference day is denoted by 3 in FIG.
  • the largest elevation angle ⁇ ma x and the angle X max of the associated reference plane in which this largest elevation angle occurs can be read from FIG. This already determines the optimal axis angle ⁇ of the prism bars.
  • the blanking curve A must now run - at least in the desired blocking area - above the trajectory curve B ': the entire area below this blanking curve A is then the blocking area in which the prismatic plate does not let any light through. This restricted area should therefore lie as little as possible above the trajectory B 'of the reference day so that as much daylight as possible is let through.
  • 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 array of curves according to FIG. 3 being rotated so that the line of symmetry M ' The line of symmetry M of the trajectory B 'in FIG.

Abstract

Avec des lucarnes ayant une inclinaison et une orientation quelconques on doit pouvoir régler l'effet pare-soleil pendant toute l'année et avoir en même temps une bonne transparence à la lumière du jour. Dans ce but, on utilise une plaque prismatique plane à l'extérieur et qui présente à l'intérieur des barres prismatiques (P) parallèles ayant une surface (P1) sur le côté de l'angle droit sans couche réfléchissante. D'après l'invention, l'autre surface sur le côté (P2) présente une couche réfléchissante et forme avec la surface non réfléchissante un angle droit. De plus, les barres prismatiques sont disposées perpendiculairement à la ligne d'intersection (L) qui est déterminée par le plan d'intersection (M) avec lequel les rayons du soleil pendant le jour le plus long forment l'angle d'incidence maximum psi max par rapport au plan de la fenêtre (F). On peut choisir pour l'angle alpha de base de la surface (P1) non réfléchissante une valeur avec laquelle on obtient un effet pare-soleil et en même temps des conditions optimales de transparence à la lumière du jour.
