Definitions
- a ridge cover is generally known, which is hood-shaped and serves as a support and ventilation element.
- the known ridge cover has a fastening section running in the longitudinal direction of the ridge, on which the ridge cover is connected to the ridge batten. This is followed in cross-section by an upwardly curved hood-shaped area which runs in the direction of the roof pitch and which overlaps the roof tiles adjacent to the ridge. So that the ridge cover can form a seal against rain and snow, it is adapted at its end overlapping the roof tiles to the profile of the roof tiles.
- the ridge cover thus has a profile which is adapted as precisely as possible to the wave valleys and wave crests of the Dachstein profile.
- ventilation troughs are provided, the outward opening of which points in the direction of the roof pitch.
- the ventilation troughs ensure an air flow from the outside of the roof into the space below the ridge tiles, whereby the air on the other side of the roof can escape again through appropriate ventilation troughs. Since the ridge cover in the area of the ridge has openings that allow air to flow from below the roof tiles into the ridge area, good overall roof ventilation is achieved. The suction effect caused by the air flow through the ventilation troughs is particularly responsible for good roof ventilation is produced.
- appropriately shaped ridge covers of the known type are required, depending on the roof pitch.
- the invention has for its object to provide a ridge cover that is suitable for different roof pitches in wide areas.
- the hood-shaped ridge cover is characterized in that, when viewed in cross section, the upper part of the ridge cover F adjoining the fastening section is arched upwards relative to the fastening section and then initially merges into a straight section which is angled downwards and which at the vertices of the profiling of the roof tiles ends that this section of the profiled part is angled inward at an obtuse angle, this profiled part having recesses adapted to the profiling of the roof tiles and having a width corresponding to the height h of the profiling, such that the ventilation troughs on the outside pointing in the direction of the roof pitch Opening area have a curvature radius r, which corresponds approximately to the profile height h of the roof tiles, and that the curvature of the ventilation troughs with the radius is determined by the fact that the circular point lies on the upper edge of the profiled part.
- the radius of curvature can increase towards the firewall.
- the section having the profiling is designed such that it sits vertically on the roof tiles with a roof pitch of 40 °.
- the obtuse angle can be 140 ° and the angle between the section running vertically downwards and the curved upper part can be 130 °.
- an elastic web protrudes at right angles from the outer end of the trough opening, which is part of the profiled section.
- the elastic web can have a width of a few millimeters and a lower material thickness than the other parts of the ridge cover. The desired elasticity is achieved due to the lower material thickness.
- the ridge cover shown in FIG. 1 has an elongated fastening section 1, to which a hood-shaped part 2 adjoins. This has an upper arched Part 3, which merges into a downward section 4, which is then followed by a profiled part 5 angled inward at an obtuse angle.
- the section 5 has semicircular recesses 6 and straight webs 7, which are adapted in their course to the profiling of the roof tiles.
- the recesses 6 overlap the crests of the Dachstein profiling.
- the ridge cover has ventilation troughs 8, at the outer opening of which the webs 7 adjoin at right angles.
- an air stream can be guided along the ventilation troughs 8 under the firebox 9.
- the air flow can emerge on the other side of the roof from corresponding ventilation troughs, wherein an air flow can be drawn in according to the direction of the arrow b by suction.
- Openings 10 are provided for the air flow running in the direction of arrow b.
- the radius of curvature r of the ventilation troughs 8 corresponds approximately to the height h of the profiles in the exemplary embodiment shown, the width of the profiled part 5 also corresponding to the height h and the course of the curvature of the ventilation troughs 8 with the radius r being determined by the circular point on the upper one Edge of the profiled part 5 lies.
- the radius of curvature must essentially be maintained in the opening area 11, whereas the radius of curvature can increase in the area 12 facing inwards.
- the profiled parts 5 overlap roof tiles 16, which rest on roof battens 17.
- the ridge stones 13, 14 lie only partially on the curved upper part 3 of the ridge covers F, since the ridge stones overlap.
- the curvature of the upper part 3 can also have a different radius than the ridge stones.

Abstract
Description
Die Erfindung betrifft eine haubenförmige Firstabdeckung gemäß Oberbegriff des Hauptanspruchs. Allgemein ist eine Firstabdekkung bekannt, die haubenförmig ausgebildet ist und als Auflage- und Belüftungselement dient. Die bekannte Firstabdeckung besitzt einen in Firstlängsrichtung verlaufenden Befestigungsabschnitt, an dem die Firstabdeckung mit der Firstlatte verbunden wird. Daran schließt sich im Querschnitt ein nach oben gewölbter haubenförmiger Bereich an, der in Dachneigungsrichtung verläuft und die dem First benachbarten Dachsteine übergreift. Damit die Firstabdeckung einen Abschluß gegen Regen und Schnee bilden kann, ist sie an ihrem die Dachsteine übergreifenden Ende an die Profilierung der Dachsteine angepaßt. Die Firstabdeckung besitzt somit ein Profil, welches möglichst genau an die Wellentäler und Wellenberge der Dachsteinprofilierung angepaßt ist.The invention relates to a hood-shaped ridge cover according to the preamble of the main claim. A ridge cover is generally known, which is hood-shaped and serves as a support and ventilation element. The known ridge cover has a fastening section running in the longitudinal direction of the ridge, on which the ridge cover is connected to the ridge batten. This is followed in cross-section by an upwardly curved hood-shaped area which runs in the direction of the roof pitch and which overlaps the roof tiles adjacent to the ridge. So that the ridge cover can form a seal against rain and snow, it is adapted at its end overlapping the roof tiles to the profile of the roof tiles. The ridge cover thus has a profile which is adapted as precisely as possible to the wave valleys and wave crests of the Dachstein profile.
Im Bereich der Wellentäler sind Belüftungsmulden vorgesehen, deren nach außen zeigende Öffnung in Dachneigungsrichtung weist. Die Belüftungsmulden gewährleisten eine Luftströmung von der Dachaußenseite in den Raum unterhalb der Firststeine, wobei die Luft an der anderen Dachseite wieder an entsprechenden Belüftungsmulden austreten kann. Da die Firstabdeckung im Bereich der Firstlatte Öffnungen besitzt, die eine Luftströmung von unterhalb der Dachsteine in den Firstbereich zuläßt, wird eine gute gesamte Dachentlüftung erzielt. Für die gute Dachentlüftung ist insbesondere die Sogwirkung verantwortlich, die durch den durch die Belüftungsmulden hindurchgführten Luftstrom erzeugt wird. Damit die Firstabdeckung im gewünschten Maße einen Schutz gegen Regen und Schnee bildet und eine gute Belüftung erzielbar ist, sind je nach Dachneigung entsprechend geformte Firstabdeckungen der bekannten Art erforderlich.In the area of the troughs, ventilation troughs are provided, the outward opening of which points in the direction of the roof pitch. The ventilation troughs ensure an air flow from the outside of the roof into the space below the ridge tiles, whereby the air on the other side of the roof can escape again through appropriate ventilation troughs. Since the ridge cover in the area of the ridge has openings that allow air to flow from below the roof tiles into the ridge area, good overall roof ventilation is achieved. The suction effect caused by the air flow through the ventilation troughs is particularly responsible for good roof ventilation is produced. In order for the ridge cover to provide protection against rain and snow to the desired extent and good ventilation can be achieved, appropriately shaped ridge covers of the known type are required, depending on the roof pitch.
Der Erfindung liegt die Aufgabe zugrunde, eine Firstabdeckung zu schaffen, die in weiten Bereichen für unterschiedliche Dachneigungen geeignet ist.The invention has for its object to provide a ridge cover that is suitable for different roof pitches in wide areas.
Die Lösung dieser Aufgabe erhält man durch die im Hauptanspruch angegebenen Merkmale. Demnach ist die haubenförmige Firstabdeckung dadurch gekennzeichnet, daß im Querschnitt gesehen der an den Befestigungsabschnitt angrenzende obere Teil der Firstabdeckung F gegenüber dem Befestigungsabschnitt nach oben gewölbt ist und dann zunächst in einen geraden, nach unten abgewinkelten Abschnitt übergeht, der an den Scheitelpunkten der Profilierung der Dachsteine endet, daß anschließend an diesen Abschnitt der profilierte Teil im stumpfen Winkel nach innen abgewinkelt ist, wobei dieser profilierte Teil an die Profilierung der Dachsteine angepaßte Aussparungen und eine der Höhe h der Profilierung entsprechende Breite hat, daß die Belüftungsmulden an dem nach außen in Dachneigungsrichtung zeigenden Öffnungsbereich einen Wölbungsradius r haben, der ungefähr der Profilhöhe h der Dachsteine entspricht, und daß der Wölbungsverlauf der Belüftungsmulden mit dem Radius dadurch bestimmt wird, daß der Zirkelpunkt auf dem oberen Rand des profilierten Teils liegt.The solution to this problem is obtained by the features specified in the main claim. Accordingly, the hood-shaped ridge cover is characterized in that, when viewed in cross section, the upper part of the ridge cover F adjoining the fastening section is arched upwards relative to the fastening section and then initially merges into a straight section which is angled downwards and which at the vertices of the profiling of the roof tiles ends that this section of the profiled part is angled inward at an obtuse angle, this profiled part having recesses adapted to the profiling of the roof tiles and having a width corresponding to the height h of the profiling, such that the ventilation troughs on the outside pointing in the direction of the roof pitch Opening area have a curvature radius r, which corresponds approximately to the profile height h of the roof tiles, and that the curvature of the ventilation troughs with the radius is determined by the fact that the circular point lies on the upper edge of the profiled part.
Durch die Anpassung des Wölbungsradius an die Profilhöhe der Dachsteine erhält man eine Firstabdeckung, die praktisch für sämtliche Dachneigungen geeignet ist.By adapting the curvature radius to the profile height of the roof tiles, a ridge cover is obtained that is suitable for practically all roof pitches.
Der Wölbungsradius kann nach innen, in Richtung Firstraum zunehmen.The radius of curvature can increase towards the firewall.
Der die Profilierung aufweisende Abschnitt ist so ausgebildet, daß er bei eine Dachneigung von 40° senkrecht auf den Dachsteinen aufsitzt. Dabei kann der stumpfe Winkel 140° betragen und der zwischen dem senkrecht nach unten verlaufenden Abschnitt und dem gewölbten oberen Teil bestehende Winkel 130° betragen.The section having the profiling is designed such that it sits vertically on the roof tiles with a roof pitch of 40 °. The obtuse angle can be 140 ° and the angle between the section running vertically downwards and the curved upper part can be 130 °.
Um eine optimale Anpassung an unterschiedliche Dachneigungen zu erhalten, steht am äußeren Ende der Muldenöffnung rechtwinklig ein elastischer Steg ab, der Teil des profilierten Abschnitts ist. Der elastische Steg kann eine Breite von wenigen Milimetern und eine geringere Materialstärke als die übrigen Teile der Firstabdeckung haben, Durch die geringere Materialstärke wird die gewünschte Elastizität erzielt.In order to optimally adapt to different roof pitches, an elastic web protrudes at right angles from the outer end of the trough opening, which is part of the profiled section. The elastic web can have a width of a few millimeters and a lower material thickness than the other parts of the ridge cover. The desired elasticity is achieved due to the lower material thickness.
