Description

Die Erfindung betrifft eine Schneefangnase, bestehend aus einem zum Dach etwa parallel verlaufenden Befestigungsteil und einen zum Schneefang vorgesehenen, etwa senkrecht dazu verlaufenden Fangteil sowie einen dessen oberes Ende mit dem Befestigungsteil verbindenden Abstützteil, wobei wenigstens in einem Teil eine in Längsrichtung verlaufende Sicke vorgesehen ist.The invention relates to a snow guard nose, consisting of a fastening part running approximately parallel to the roof and a catching part provided for the snow guard, approximately perpendicular to it, and a supporting part connecting the upper end thereof to the fastening part, a bead running in the longitudinal direction being provided in at least one part.

Derartige bekannte :Schneefangnasen sind aus einem langen Blechstreifen geformt, der an einem Ende zur Bildung des Fangteiles in einem Winkel von etwa 90° umgebogen und am Ende der Fangnase wieder in einem Winkel von etwa 45° zur Bildung des Abstützteiles umgebogen ist. Zur Versteifung wird im Fang-und bzw. oder Abstützteil eine oder auch zwei Sicken angeordnet. Diese Versteifung hat sich jedoch als nicht ausreichend erwiesen.Such well-known: snow guard lugs are formed from a long sheet metal strip, which at one end to form the Catch part is bent at an angle of about 90 ° and bent again at the end of the catch nose at an angle of about 45 ° to form the support part. For stiffening, one or two beads are arranged in the catch and / or support part. However, this stiffening has proven to be insufficient.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine Schneefangnase der eingangs beschriebenen Art auf konstruktiv einfache Weise noch stärker zu versteifen.The object of the present invention is to stiffen a snow guard nose of the type described above even more in a structurally simple manner.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß wenigstens in einem Teil wenigstens drei Sicken vorgesehen sind, von denen die Vertiefung wenigstens einer Sicke im Vergleich zur Vertiefung der anderen Sicken in entgegengesetzter Richtung ausgebildet ist. Durch eine derartige "Gegensickenausbildung" wird die Biegefestigkeit bei geringem Mehraufwand für die Prägung einer zusätzlichen Sicke in überraschender Weise wesentlich erhöht. Zweckmäßigerweise wird der Abstützteil zur Vermeidung eines Ausknickens bei zu hoher Schneelast auf diese Weise-verstärkt. Es kann aber ebenso auch der Fang-und Befestigungsteil mit einer derartigen Gegensicke ausgebildet sein. Dabei ist zur Bildung eines gleichmäßigen Biegemomentes eine zur Längsachse der einzelnen Fangnasenteile symmetrische Ausbildung von Vorteil.This object is achieved in that at least in one part at least three beads are provided, of which the recess of at least one bead is formed in the opposite direction compared to the recess of the other beads. Such a "counter bead formation" surprisingly significantly increases the bending strength with little additional effort for embossing an additional bead. The supporting part is expediently reinforced in this way in order to avoid buckling if the snow load is too high. However, the catching and fastening part can also be designed with such a counter bead. In this case, a formation that is symmetrical with respect to the longitudinal axis of the individual catching nose parts is advantageous for forming a uniform bending moment.

Eine bevorzugte Ausbildung der Erfindung besteht darin, daß drei Sicken vorgesehen sind, wobei die Vertiefung der beiden äußeren Sicken in gleicher Richtung verlaufend ausgebildet ist. Eine derartige Ausbildung ermöglicht bei einem minimalen Mehraufwand bereits eine wesentliche Versteifung.A preferred embodiment of the invention is that three beads are provided, the recess of the two outer beads being designed to run in the same direction. Such a design enables substantial stiffening with minimal additional effort.

Gemäß einer anderen Ausführungsform der Erfindung ist vorgesehen, daß die Sickenam Fang-und Abstützteil angeordnet sind, wodurch eine wesentlich, höhere Belastung der Schneefangnase möglich ist.According to another embodiment of the invention it is provided that the bead n is arranged on the catching and supporting part are, whereby a significantly higher load on the snow guard nose is possible.

Einer anderen vorteilhaften Ausbildung der Erfindung entsprechend kann die Sicke mit einer zur Längsmitte hin konstant zunehmenden Vertiefung ausgebildet sein. Eine derartige konische Sicke führt zu einer weiteren Erhöhung der Biegefestigkeit.According to another advantageous embodiment of the invention, the bead can be formed with a depression that increases constantly towards the longitudinal center. Such a conical bead leads to a further increase in the bending strength.

Schließlich kann gemäß einer anderen vorteilhaften Ausführung der Erfindung die mittlere Sicke des Fangteiles bis etwa zum Mittelbereich des Befestigungsteiles verlaufend ausgebildet sein. Eine derartige Ausbildung verhindert in vorteilhafter Weise ein durch sehr hohe auf den Fangteil einwirkende Schneelasten bedingtes Abheben.insbesondere des mittleren Bereiches von der Dachoberfläche.Finally, according to another advantageous embodiment of the invention, the central bead of the catching part can be designed to extend approximately to the central region of the fastening part. Such an embodiment advantageously prevents lifting due to very high snow loads acting on the catching part, in particular of the central area from the roof surface.

Im Folgenden wird die Erfindung an Hand zweier in der Zeichnung dargestellter Ausführungsbeispiele näher beschrieben,The invention is described in more detail below with reference to two exemplary embodiments shown in the drawing,

Es zeigen:

  • Fig.1 eine Perspektivansicht einer Schneefangnase,
  • Fig.2 einen Schnitt durch die Schneefangnase nach Fig.1, gemäß der Line. II-II,
  • Fig.3 eine Seiten- und
  • Fig.4 eine Draufsicht eines weiteren Ausführungsbeispieles einer Schneefangnase gemäß der Erfindung.
Show it:
  • 1 is a perspective view of a snow guard nose,
  • 2 shows a section through the snow guard nose according to FIG. 1, according to the line. II-II,
  • 3 shows a side and
  • 4 shows a plan view of a further exemplary embodiment of a snow guard nose according to the invention.

Eine aus Blech geformte Schneefangnase 1 setzt sich aus einem der Dachoberfläche benachbarten Befestigungsteil 2, einem senkrecht zu diesem angeordneten Fangteil 3 und einem diesen mit dem Befestigungsteil verbindenden Abstützteil 4 zusammen. Sowohl der Fang-als auch Abstützteil 3,4 weist drei parallel zueinander angeordnete und in Längsrichtung der Teile verlaufende Sicken 5 auf. Wie insbesondere auch durch Fig.2 ersichtlich, ist die Vertiefung der mittleren Sicke 5 des Abstützteiles 4 im Vergleich zur Vertiefung der angrenzenden Sicken;5 in entgegengesetzter Richtung ausgebildet. Im dargestellten-Ausführungsbeispiel ist die Sickenform halbkreisförmig, diese känn jedoch ebenso trapezförmig oder dgl. ausgebildet sein. Ebenso können auch die beiden äußeren Sicken 5 des Abstützteiles 4 in Richtung zum Fangteil 3 vertieft ausgebildet sein, während die mittlere Sicke 5 dann in Gegenrichtung geformt ist. Der Befestigungsteil 2 weist in seinem zwischen Fang-und Abstützteil 3,4 liegenden Bereich ebenso zwei Sicken 6 auf.A snow guard nose 1 formed from sheet metal is composed of a fastening part 2 adjacent to the roof surface, a catching part 3 arranged perpendicularly to this and a supporting part 4 connecting it to the fastening part. Both the catching and the supporting part 3, 4 have three arranged parallel to one another and in the longitudinal direction Divide running beads 5. As can be seen in particular from FIG. 2, the depression of the central bead 5 of the support part 4 is formed in the opposite direction compared to the depression of the adjacent beads 5. In the exemplary embodiment shown, the bead shape is semicircular, but these can also be trapezoidal or the like. Likewise, the two outer beads 5 of the support part 4 can also be recessed in the direction of the catching part 3, while the central bead 5 is then shaped in the opposite direction. The fastening part 2 also has two beads 6 in its area lying between the catching and supporting part 3, 4.

Die in Fig.3 und 4 dargestellte Schneefangnase 1 weist im Bereich des Abstützteiles 4 eine-speziell ausgebildete mittlere Sicke 7 auf. Diese weist eine in Richtung zum Fang-und Befestigungsteil 3,2 gerichtete Vertiefung 8 auf, die in Richtung zur Längsmitte der Sicke konstant zunimmt. Diese konisch zur Mitte verlaufende.Sicke 7 gewährleistet eine besonders stabile Ausbildung der Schneefangnase 1. Die mittlere Sicke 9 erstreckt sich vom Fangteil 3 bis zum Mittelbereich des Abstützteiles 2 und verhindert dadurch ein Aufheben des Abstützteiles bei zu hoher, auf den Fang- teil 3 einwirkender Schneelast..The snow guard nose 1 shown in FIGS. 3 and 4 has a specially formed central bead 7 in the region of the support part 4. This has a depression 8 directed in the direction of the catching and fastening part 3. 2, which increases constantly in the direction of the longitudinal center of the bead. This conical bead 7 ensures a particularly stable formation of the snow guard nose 1. The central bead 9 extends from the catching part 3 to the central region of the supporting part 2 and thereby prevents the supporting part from being lifted if the catching part 3 is too high Snow load ..
