Abstract

With dormer windows of any inclination and orientation, it should be possible to adjust the sunshade effect throughout the year and to have at the same time a good transparence to daylight. To this effect, there is used a prismatic plate, flat at the outside, and which is provided inside with parallel prismatic bars (P) having a surface (P1) free of reflecting layer on the right angle side. According to the invention, the other surface on the side (P2) is provided with a reflecting layer and forms with the non reflecting surface a right angle. Furthermore, the prismatic bars are arranged perpendicularly to the intersection line (L) which is defined by the intersection plane (M) with which the solar beams, during the longest day, form the maximum incidence angle, psi max with respect to the plane of the window (F). For the angle alpha of the base of the non reflecting surface (P1), a value may be selected with which there is obtained a sunshade effect and at the same time optimum conditions of transparency to daylight.

Description

Die Erfindung betrifft ein Dachfenster gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a roof window according to the preamble of claim 1.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Fenster vorgegebener Neigung und Ausrichtung den Durchtritt von Sonnenstrahlen in einer Sperrzeit zwischen zwei Zeitpunkten eines Bezugstages zu vermeiden, die Lichtdurchlässigkeit im übrigen aber so wenig wie möglich zu beeinträchtigen. Insbesondere soll der Sperrbereich der Prismenplatte nicht grösser sein, als es im Hinblick auf die vollständige Ausblendung der Sonne in dem Sperrbereich des Bezugstages erforderlich ist.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. In particular, 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.

Die erfindungsgemässe Lösung dieser Aufgabe ist in Patentanspruch 1 gekennzeichnet. Sie beruht auf der Feststellung, dass die Ausblendkurve eines solchen Fensters in einem Besonnungsdiagramm gleichartig verläuft wie die Bahnkurven der Sonne, dass sich ferner durch geeignete Wahl des Achswinkels der Prismenstäbe die Mittelachse der Ausblendkurve relativ zur Mittelachse der Sonnenbahn schwenken und dass sich ferner die Ausblendkurve durch entsprechende Wahl des Basiswinkels der Prismenstäbe sehr dicht an die Bahnkurve heranrücken lässt; dadurch ist eine Minimierung der Fläche zwischen Ausblendkurve und Bahnkurve möglich, so dass das Fenster ein Maximum an Tageslicht durchlässt.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.

In der Regel wird als Bezugstag für die Ausblendbedingung der längste Tag des Jahres mit dem höchstmöglichen Sonnenstand gewählt; es ist dann während des ganzen Jahres eine vollständige Ausblendung der Sonne erreichbar. Aus der DE-A-2615379 ist eine aussen ebene Prismenplatte bekannt, die auf der Innenseite horizontale, parallel zueinander verlaufende Prismen mit dreieckigem Querschnitt aufweist, wobei eine Kathete mit der Aussenfläche einen spitzen Winkel einschliesst. Die andere Kathete ist jedoch weder spiegelnd noch im rechten Winkel zur ersten angeordnet.As a rule, the longest day of the year with the highest possible position of the sun is chosen as the reference day for the fading condition; it is then possible to completely hide the sun throughout the year. From DE-A-2615379 an outer flat prism plate is known which has horizontal, parallel to one another prisms with a triangular cross-section on the inside, a cathetus making an acute angle with the outer surface. However, the other catheter is neither reflective nor at right angles to the first.

Eine solche Prismenplatte lässt das hohe, über einem bestimmten Grenzwinkel auftretende Zenitlicht in den Raum eintreten und reflektiert das unter diesem Grenzwinkel auftreffende Licht, also insbesondere das direkte Sonnenlicht. Diese Aussage gilt allerdings nur streng für eine Querschnittsebene senkrecht zu der Oberfläche und zu der Längsachse der Prismenplatte; über ihre Ausblendeigenschaften quer dazu sowie eine gezielte Zuordnung zu der Sonnenbahn - insbesondere bei geneigter Fensterfläche - finden sich keine Anhaltspunkte.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. However, 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.

Aus der FR-A-2185743 ist ferner eine Jalousie für horizontale Dachfenster mit äquidistanten Lamellen bekannt, die senkrecht zu einer in Nord-Süd-Richtung verlaufenden Vertikalebene angeordnet sind; dies gilt auch dann, wenn das Fenster nicht in Ost-West-Richtung liegt, so dass die Lamellen dann in einem spitzen Winkel zu der horizontalen Unterkante des Fensters verlaufen. Eine solche Jalousie blendet die Sonne aus und lässt gleichzeitig das Zenitlicht durch. Wie bei allen Lamellenjalousien reicht aber dieser Durchlassbereich oberhalb des Grenzwinkels nicht bis an 180°, ausserdem ist diese Lösung nur bei ebenen Dachfenstern und bei nach Süd ausgerichteten Vertikalfenstern anwendbar, da nur in diesen Fällen die Lamellen parallel zur Ost-West-Richtung orientierbar sind.From FR-A-2185743 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. As with all louvre blinds, however, 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.

Schliesslich sind aus DE-C 831449 und FR-A 2463254 Prismenplatten mit aussenliegenden Prismenstäben mit dreieckigem Querschnitt bekannt, durch die jedoch das Licht im obersten Winkelbereich - also gerade das Zenitlicht - ausgeblendet wird.Finally, from DE-C 831449 and FR-A 2463254 prismatic plates with external prismatic rods with a triangular cross-section are known, however, by means of which the light in the uppermost angular range - that is to say precisely the zenith light - is masked out.

Die Erfindung wird anhand der Figuren näher erläutert; es zeigen:

  • Fig. 1 schematisch ein Fenster mit den Bestimmungsgrössen,
  • Fig. 2 ein Besonnungsdiagramm mit Bahnkurve B' und Ausblendkurve A sowie
  • Fig. 3 eine Schar von Ausblendkurven für einen Prismenstab mit unterschiedlichem Basiswinkel.
The invention is illustrated by the figures; show it:
  • 1 schematically shows a window with the parameters,
  • Fig. 2 is a tanning diagram with trajectory curve B 'and blanking curve A and
  • Fig. 3 is a family of masking curves for a prism rod with different base angles.

In Fig. 1 ist ein Dachfenster mit der Fensterfläche F schematisch dargestellt, wobei diese Fensterfläche gegenüber der Horizontalebene H um den Winkel β geneigt und in der angegebenen Weise gegen Süd-Ost ausgerichtet ist. Die Fensterfläche F wird von einer Prismenplatte ausgefüllt, die auf der Aussenseite eine ebene Basisfläche PO und auf der Innenseite lückenlos aneinandergrenzende Prismenstäbe P mit den rechtwinklig zueinander verlaufenden Kathetenflächen P1 und P2 aufweist (vgl. das vergrösserte Schnittbild in der Verlängerung der Schnittlinie L in Fig. 1).In Fig. 1, a roof window with the window surface F is shown schematically, this window surface being inclined by the angle β 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).

Die Längsachsen der Prismenstäbe P verlaufen senkrecht zu einer Schnittlinie L und schliessen somit einen Achswinkel y - gemessen in der Fensterebene F - mit der horizontalen Begrenzungskante K ein. Die Schnittlinie L ist gegeben durch den Schnitt der Fensterfläche F mit derjenigen auf ihr senkrecht stehenden Bezugsebene E, in der der grösste Höhenwinkel der Sonne an dem Bezugstag und innerhalb des Sperrbereiches auftritt, und zwar gemessen in der Bezugsebene E gegen die Schnittlinie L. Die Bahnkurve der Sonne am Bezugstag ist in Fig. 1 mit B bezeichnet.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.

Eine der Kathetenflächen, nämlich P2, der Prismenstäbe P ist auf der Innenseite verspiegelt. Die Prismenstäbe sind so angeordnet, dass die Spitze des grössten HöhenwinkeIsψ max auf die verspiegelte Kathethenfläche P2 hinweist.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 ψ max indicates the mirrored catheter surface P2.

Fig. 2 zeigt qualitativ den Verlauf der Sonnenbahn B': Sie gibt den jeweiligen Höhenwinkel y eines Sonnenstrahles D gemessen in der auf der Fensterebene E senkrechten Bezugsebene abhängig von dem Winkel X der Schnittlinie L dieser Bezugsebene mit der Fensterebene gemessen gegen die Horizontalkante K (entsprechend den Definitionen für die Bezugsebene E in Fig. 1).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).

Aus Fig. 2 lässt sich nun der grösste Höhenwinkel ψ max und der Winkel X max der zugehörigen Bezugsebene, in der dieser grösste Höhenwinkel auftritt, ablesen. Damit ist bereits der optimale Achswinkel y der Prismenstäbe bestimmt.The largest elevation angle ψ 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.

Die Ausblendkurve A muss nun - zumindest in dem gewünschten Sperrbereich - oberhalb der Bahnkurve B' verlaufen: Das gesamte Gebiet unterhalb dieser Ausblendkurve A ist dann der Sperrbereich, in dem die Prismenplatte kein Licht durchlässt. Der über der Bahnkurve B' des Bezugstages liegende Teil dieses Sperrbereiches sollte möglichst klein sein, damit möglichst viel Tageslicht durchgelassen wird. Dies ist durch geeignete Wahl des Basiswinkels a der Prismenstäbe möglich: Hierzu werden die Ausblendkurven von Prismenstäben mit unterschiedlichem Basiswinkel gemäss Fig. 3 aufgenommen und dann mit der auszublendenden Bahnkurve verglichen, wobei die Kurvenschar nach Fig. 3 so gedreht wird, dass sich die Symmetrielinie M' mit der Symmetrielinie M der Bahnkurve B' in Fig. 2 deckt: Die beiden Diagramme sind dann unmittelbar vergleichbar, weil sie für denselben Bezugswinkel X der Bezugsebene E einmal den Höhenwinkel ψ der Sonne in dieser Bezugsebene und zum anderen den Ausblendwinkel eines senkrecht zu dieser Bezugsebene E verlaufenden Prismenstabes P wiedergeben.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. This is possible by a suitable choice of 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. 2: The two diagrams are then directly comparable, because for the same reference angle X of the reference plane E they once the height angle ψ of the sun in this reference plane and on the other hand the fade-out angle one perpendicular to this Represent the reference plane E of the extending prism rod P.

Es ist daher jetzt nur noch die der Bahnkurve B' am nächsten liegenden Ausblendkurve A auszusuchen, der in diesem Fall ein Basiswinkel a von 34° zugeordnet ist. Offensichtlich könnte der Abstand zwischen Ausblend- und Bahnkurve durch Wahl eines noch etwas geringeren Basiswinkels weiter reduziert werden.It is therefore now only necessary to select the masking curve A which is closest to the trajectory curve B 'and in this case is assigned a base angle a of 34 °. Obviously, the distance between the masking and trajectory curve could be further reduced by choosing a slightly lower base angle.
