Description

Die vorliegende Erfindung bezieht sich auf einen Schneehalter gemäss dem Oberbegriff des Patentanspruches 1.The present invention relates to a snow holder according to the preamble of claim 1.

Bekannte Schneehalter weisen den Nachteil auf, dass für jede Dachziegeldicke und Dachziegelart ein anderer Schneehaltertyp verwendet werden muss.Known snow holders have the disadvantage that a different type of snow holder must be used for each roof tile thickness and type of roof tile.

Beispielsweise ist aus der CH-A-533 216 eine Schneefangvorrichtung an einem mit Dachplatten gedeckten Schrägdach vorbekannt. Diese Schneefangvorrichtung eignet sich jedoch nicht für beliebige Dachziegeldicken und -formen. Im weiteren muss diese Schneefangvorrichtung aus relativ sehr dickem Material gefertigt werden, um die grossen Schneelasten aufzufangen. Dadurch wird der obenliegende Ziegel angehoben. Im weiteren kann eine Schneefangvorrichtung gemäss der obgenannten Druckschrift, welche ja aus relativ dickem Material gefertigt werden muss, nicht über einen mit einem Profil versehenen Ziegel gebracht werden, da die Schneefangvorrichtung zu wenig federt.For example, from CH-A-533 216 a snow guard device is known on a sloping roof covered with roof tiles. However, this snow guard is not suitable for any roof tile thickness and shape. Furthermore, this snow guard must be made of relatively very thick material in order to absorb the large snow loads. This will raise the brick above. Furthermore, a snow guard device according to the above-mentioned document, which must be made of relatively thick material, cannot be placed over a brick provided with a profile, since the snow guard device does not spring enough.

Aus der EP-A-0 052 080 ist eine Schneehaltevorrichtung für mit Asbestzementplatten gedeckte Dächer vorbekannt. Diese Schneehaltevorrichtung eignet sich nicht für Tonziegel und Betonziegel verschiedenster Dicke. Der Bügel 19 kann nicht gegenüber dem Rückhalteteil 6 verstellt werden, insbesondere nicht arretierbar verstellt werden. Der Bügel 19 ist nicht zum Umgreifen des unteren Endes eines Dachziegels bestimmt.A snow holding device for roofs covered with asbestos cement slabs is previously known from EP-A-0 052 080. This snow holding device is not suitable for clay bricks and concrete bricks of various thicknesses. The bracket 19 can not be adjusted relative to the retaining part 6, in particular can not be adjusted lockable. The bracket 19 is not intended for gripping the lower end of a roof tile.

Aus der CH-642 706 ist ein Verfahren zur Herstellung eines Dachschneefängers vorbekannt. Dieser Dachschneefänger eignet sich jedoch ebenfalls nicht zur Verwendung zusammen mit Ziegeln, sondern lediglich zur Verwendung mit Dachschieferplatten.From CH-642 706 a method for producing a roof snow catcher is already known. However, this roof snow catcher is also not suitable for use with bricks, but only for use with roof slate panels.

Aus der NL-C-25 592 ist eine Sturmklammer vorbekannt, welche den Zweck hat, zu verhindern, dass Ziegel vom Dach abgehoben werden können. Diese Sturmklammer kann nicht verwendet werden, um Schneehalter für beliebige Dachziegeldicken und -formen auf den Dächern zu befestigen.A storm clamp is known from NL-C-25 592, which has the purpose of preventing tiles from being lifted off the roof. This storm clamp cannot be used to attach snow holders for any roof tile thickness and shape to the roof.

Aus der CH-574 026 ist ein Schneehalter für Dächer vorbekannt, der sich jedoch nicht zur Verwendung mit beliebigen Dachziegeldicken und -formen eignet.A snow holder for roofs is already known from CH-574 026, but is not suitable for use with any roof tile thickness and shape.

Aus der DE-A-26 22 084 ist eine Halteklammer für Firsthauben, die sich nicht als Schneehalter für beliebige Dachziegeldicken und -formen eignet, vorbekannt.From DE-A-26 22 084 a retaining clip for ridge hoods, which is not suitable as a snow holder for any roof tile thickness and shape, is known.

Es ist deshalb eine Aufgabe der vorliegenden Erfindung, die obgenannten Nachteile zu vermeiden und einen Schneehalter zu schaffen, der für beliebige Dachziegeldicken und -formen verwendet werden kann, wobei er für die gewählte Dicke arretiert werden können soll. Dies wird erfindungsgemäss erzielt durch die Merkmale des unabhängigen Patentanspruches 1.It is therefore an object of the present invention to avoid the disadvantages mentioned above and to provide a snow holder which can be used for any roof tile thickness and shape, and which should be able to be locked for the selected thickness. According to the invention, this is achieved by the features of independent patent claim 1.

Bevorzugte Ausführungsbeispiele der Erfindung ergeben sich aus den abhängigen Ansprüchen.Preferred embodiments of the invention result from the dependent claims.

Bekannte Schneehalter werden jeweils am oberen Ende des Dachziegels montiert. Dadurch kann Widerschwallwasser zwischen zwei Ziegel und damit ins Dach gelangen. Ein Vorteil des erfindungsgemässen Schneehalters liegt darin, dass er am unteren Ende eines Dachziegels montiert wird, wodurch vermieden wird, dass Widerschwallwasser eindringen kann.Known snow holders are each mounted on the upper end of the roof tile. This means that flood water can get between two bricks and thus into the roof. An advantage of the snow holder according to the invention lies in the fact that it is mounted on the lower end of a roof tile, as a result of which it is avoided that flood water can penetrate.

Bekannte, am oberen Ende des Dachziegels montierte Schneehalter weisen im weiteren den Nachteil auf, dass, wenn der Dachdecker auf den Schneerückhalteteil steht, der Schneehalter kippt und den oberen Ziegel abhebt. Dieser Nachteil kann beim erfindungsgemässen Schneehalter nicht auftreten.Known snow holders mounted on the upper end of the roof tile also have the disadvantage that when the roofer stands on the snow retention part, the snow holder tilts and lifts the upper tile. This disadvantage cannot occur with the snow holder according to the invention.

Bei der Verwendung von Schiebeziegeln mussten bisherige Schneehalter kürzer oder länger gefertigt werden, da sie am oberen Ende des Ziegels eingehängt wurden. Der erfindungsgemässe Schneehalter kann bei Schiebeziegeln in beliebiger Lage derselben verwendet werden.When using sliding bricks, previous ones had to Snow holders can be made shorter or longer because they were hung on the upper end of the tile. The snow holder according to the invention can be used in sliding bricks in any position thereof.

Bekannte Schneehalter wiesen den Nachteil auf, dass sie beim Drauftreten umkippten, den Ziegel abhoben, vom Ziegel wegrutschten, und dabei eine Unfallgefahr bestand. Der erfindungsgemässe Schneehalter gewährleistet beim Begehen des Daches einen sicheren Halt.Known snow holders had the disadvantage that they tipped over when they were stepped on, lifted off the brick, slipped off the brick, and there was a risk of an accident. The snow holder according to the invention ensures a secure hold when walking on the roof.

Ein weiterer Vorteil des erfindungsgemässen Schneehalters besteht darin, dass die Schneelast besser als bei bekannten Schneehaltern verteilt wird, wobei sich die Schneelast zum grossen Teil direkt über einer Dachquerlatte befindet. Dadurch wird die Lebensdauer der Dachziegel erhöht.A further advantage of the snow holder according to the invention is that the snow load is distributed better than in known snow holders, the snow load being largely directly above a crossbar. This increases the lifespan of the roof tiles.

Ein zusätzlicher Vorteil des erfindungsgemässen Schneehalters besteht in der geringen Auflagefläche desselben auf den Dachziegeln, wodurch der Ziegel nach Regen oder Schnee besser und schneller austrocknen kann, so dass im Gegensatz zu den bekannten Schneehaltern sich die Engobierung und die Tonmasse des Ziegels nicht zersetzen kann und dadurch der Ziegel wasserdurchlässig wird.An additional advantage of the snow holder according to the invention is the small contact area of the same on the roof tiles, as a result of which the brick can dry out better and faster after rain or snow, so that, in contrast to the known snow holders, the engobing and the clay mass of the brick cannot decompose and thereby the brick becomes permeable to water.

Der Schneehalter 100 gemäss Fig. 1 umfasst einen integriert ausgebildeten Kunststoffteil 102 und einen in diesem verschieb- und arretierbar gehaltenen Haltebügel 103 aus Metall. Der Kunststoffteil 102 weist einen Absatz 104 auf, der oben auf einem Tonziegel 105 aufliegt. Der Metallbügel 103 umgreift mit einem Ansatz 106 an dessen Ende den Absatz 107 am unteren Ende des Tonziegels 105. Im weiteren ist aus der Fig. 1 noch der unten liegende Tonziegel 108 sowie ein Dachbalken 109 ersichtlich. Der Kunststoffteil 102 des Schneehalters 100 weist einen auf dem oberen Ziegel 105 aufliegenden Schneerückhalteteil 110 und einen auf dem unteren Ziegel 108 aufliegenden Auflageteil 111 auf. Am unteren, auf dem Ziegel 105 aufliegenden Ende des Schneerückhalteteils 110 ist eine Nase 112 flexibel mit dem Schneerückhalteteil 110 verbunden. Die Nase 112 steht etwas schräg nach unten ab, wobei die Distanz a vorzugsweise etwa 2 mm beträgt. Im weiteren weist der Kunststoffteil 102 einen Absatz 113 bei Verwendung von Betonziegeln auf. Innerhalb des Teiles 102 ist ein Führungskanal 114 zur Aufnahme des vertikalen Teiles 115 des Bügels 103 vorgesehen. Der Bügel 103 liegt mit seinem waagrechten Teil 116 auf dem unteren Tonziegel 108 auf. Im Bereich des Führungsteils 114 ist eine Rasterplatte 117 mit Rasterzähnen 118 angeordnet. Im weiteren ist eine vertikale Strebe 119 vorgesehen. Im oberen Bereich 120 des vertikalen Teils 115 des Bügels 103 ist eine Nase 121 umgebogen, wobei um den oberen Bereich 120 des Bügels 103 und die Unterseite der Nase 121 eine Metallfeder 122 gelegt ist.The snow holder 100 according to FIG. 1 comprises an integrally formed plastic part 102 and a holding bracket 103 made of metal which can be moved and locked therein. The plastic part 102 has a shoulder 104, which rests on top of a clay brick 105. The metal bracket 103 encompasses a shoulder 106 at the end of the shoulder 107 at the lower end of the clay tile 105. Furthermore, the clay tile 108 located below and a roof beam 109 can also be seen from FIG. 1. The plastic part 102 of the snow holder 100 has a snow retention part 110 resting on the upper brick 105 and a support part 111 resting on the lower brick 108. At the lower end of the snow retention part 110 resting on the brick 105, a nose 112 is flexibly connected to the snow retention part 110. The nose 112 protrudes somewhat obliquely downwards, the distance a preferably being approximately 2 mm. Furthermore, the plastic part 102 has a shoulder 113 when using concrete bricks. A guide channel 114 is provided within the part 102 for receiving the vertical part 115 of the bracket 103. The bracket 103 lies with its horizontal part 116 on the lower clay brick 108. A grid plate 117 with grid teeth 118 is arranged in the region of the guide part 114. Furthermore, a vertical strut 119 is provided. A nose 121 is bent in the upper region 120 of the vertical part 115 of the bracket 103, a metal spring 122 being placed around the upper region 120 of the bracket 103 and the underside of the nose 121.

Zur Befestigung des Schneehalters 100 am Ziegel 105 wird der Absatz 104 mit der Nase 112 auf die Oberfläche des Ziegels 105 gelegt, der Bügel 103 in den Führungskanal eingeschoben, bis der horizontale Teil 116 des Bügels 103 unten am Absatz 107 des Ziegels anliegt, wobei dann der Kunststoffteil 102 des Schneehalters 100 und der Bügel 103 infolge der flexiblen Nase 112 noch etwas zusammengedrückt werden können, bis dass die Feder 122 zwischen zwei Rasterzähnen 118 einrastet. Die federnde Anordnung der Nase 112 wirkt als Distanzausgleich. Der Bügel 103 kann alsdann nicht mehr aus dem Führungskanal 114 resp. dem Kunststoffteil 102 entfernt werden, da die Nase 121 im oberen Bereich 120 des vertikalen Teils 115 des Bügels 103 verhindern, dass sich die Feder 122 nach oben umbiegen kann. Die Distanz b zwischen der Nase 121 und den Rasterzähnen 118 beträgt vorzugsweise etwa 1 bis 1,5 mm. Der Absatz 104 des Teils 102 des Schneehalters 100, der horizontale Teil 116 und der Ansatz 106 des Metallbügels 103 umfassen das Ende des Ziegels 105 zangenförmig. Je grösser der Schneedruck auf den Schneerückhalteteil 110 ist, umso grösser wird die Klemmwirkung der zangenförmigen Teile des Schneehalters, nämlich des Absatzes 104, des horizontalen Teils 116 und des Ansatzes 106 des Metallbügels 103 auf das Ende 107 des Ziegels 105. Durch die Tatsache, dass der Auflageteil 111 des Schneehalters 100 auf dem unteren Ziegel 108 fest aufliegt, kann der Schneerückhalteteil 110 des Schneehalters 100 sehr grosse Schneelasten aufnehmen. Der auf der Nase 112 befindliche Schnee drückt den Schneehalter noch zusätzlich auf den Ziegel 105.To fasten the snow holder 100 to the brick 105, the shoulder 104 is placed with the nose 112 on the surface of the brick 105, the bracket 103 is pushed into the guide channel until the horizontal part 116 of the bracket 103 rests below the shoulder 107 of the brick, in which case the plastic part 102 of the snow holder 100 and the bracket 103 can still be pressed together somewhat as a result of the flexible nose 112 until the spring 122 engages between two raster teeth 118. The resilient arrangement of the nose 112 acts as a distance compensation. The bracket 103 can then no longer from the guide channel 114 or. the plastic part 102, since the nose 121 in the upper region 120 of the vertical part 115 of the bracket 103 prevents the spring 122 from being able to bend upwards. The distance b between the nose 121 and the raster teeth 118 is preferably approximately 1 to 1.5 mm. The shoulder 104 of the part 102 of the snow holder 100, the horizontal part 116 and the shoulder 106 of the metal bracket 103 encompass the end of the brick 105 in the form of pliers. The greater the snow pressure on the snow retaining part 110, the greater the clamping effect of the pincer-shaped parts of the snow holder, namely the shoulder 104, the horizontal part 116 and the extension 106 of the metal bracket 103 on the end 107 of the brick 105. Due to the fact that the support part 111 of the snow holder 100 lies firmly on the lower brick 108, the snow retention part 110 of the snow holder 100 can absorb very large snow loads. The snow on the nose 112 additionally presses the snow holder onto the brick 105.

In Fig. 2 ist eine Ansicht von unten des Ausführungsbeispiels gemäss Fig. 1 dargestellt. Zusätzlich zur Fig. 9 ist noch eine Längsverstärkungsrippe 123 ersichtlich. Der Führungskanal 114 für den Bügel 103 umfasst an den Seitenteilen 124 und 125 des Kunststoffteiles 102 anliegende vertikale Führungsteile 126, 127, 128 und 129, welche über Stege 130, 131, 132 und 133 mit der vertikalen Strebe 119 resp. mit der Rasterplatte 117 verbunden sind.FIG. 2 shows a view from below of the exemplary embodiment according to FIG. 1. In addition to FIG. 9, a longitudinal reinforcement rib 123 can also be seen. The guide channel 114 for the bracket 103 comprises on the side parts 124 and 125 of the plastic part 102 adjacent vertical guide parts 126, 127, 128 and 129, which via webs 130, 131, 132 and 133 with the vertical strut 119 and. are connected to the grid plate 117.

Aus Fig. 3 ist eine perspektivische Ansicht des Haltebügels 103 ersichtlich. Im oberen Bereich 120 des vertikalen Teils 115 des Haltebügels 103 ist eine rechteckförmige Oeffnung 134 ausgespart, wobei an deren oberem Ende die Nase 121 abgebogen ist. Die Nase 121 schliesst mit dem vertikalen Teil 115 des Haltebügels 103 vorzugsweise etwa einen Winkel von 80° ein.3 is a perspective view of the bracket 103 can be seen. In the upper region 120 of the vertical part 115 of the holding bracket 103, a rectangular opening 134 is recessed, the nose 121 being bent at the upper end thereof. The nose 121 preferably forms an angle of approximately 80 ° with the vertical part 115 of the holding bracket 103.

In Fig. 4 ist die Feder 122 perspektivisch dargestellt, welche um einen oberen Bereich 120 des vertikalen Teils 115 des Haltebügels 103 sowie um die Unterseite der Nase 121 gelegt wird. Der um den oberen Bereich 120 des Bügels 103 gelegte Teil der Feder 122 umfasst einen vertikalen Teil 135, einen umgebogenen Teil 136 sowie einen abgebogenen Teil 137. An den vertikalen Teil 135 schliesst ein abgewinkelter Teil 138 an, der an der Unterseite der Nase 121 anliegt.4, the spring 122 is shown in perspective, which is placed around an upper region 120 of the vertical part 115 of the holding bracket 103 and around the underside of the nose 121. The part of the spring 122 placed around the upper region 120 of the bracket 103 comprises a vertical part 135, a bent part 136 and a bent part 137. An angled part 138 adjoins the vertical part 135 and bears against the underside of the nose 121 .

In Fig. 5 ist eine Seitenansicht teilweise im Schnitt eines zweiten Ausführungsbeispieles eines Schneehalters 140 dargestellt. Gleiche Teile wie beim ersten Ausführungsbeispiel sind bei diesem zweiten Ausführungsbeispiel mit gleichen Bezugszeichen versehen. Dieses Ausführungsbeispiel umfasst ebenfalls einen integriert ausgebildeten Kunststoffteil 141 sowie einen Haltebügel 103. Der Haltebügel 103 weist ebenfalls einen vertikalen Teil 115, einen horizontalen Teil 116 sowie einen vom horizontalen Teil 116 abgebogenen Ansatz 106 auf. Bei diesem zweiten Ausführungsbeispiel ist die Anwendung des Schneehalters bei einem Betonziegel 142 dargestellt, wobei in diesem Falle der Absatz 113 des Kunststoffteiles 141, der horizontale Teil 116 und der Ansatz 106 des Haltebügels 103 das dachwärts gesehen untere Ende 146 des Betonziegels zangenförmig umfassen. Das in Fig. 5 gezeigte zweite Ausführungsbeispiel wäre selbstverständlich auch bei Tonziegeln, wie in Fig. 1 dargestellt, anwendbar, wobei dann der Absatz 104 auf dem Ziegel aufliegen würde. Der Kunststoffteil 141 umfasst ebenfalls eine Rasterplatte 117 mit Rasterzähnen 118. Der Führungskanal 143 für den Haltebügel 103 weist eine parallel zur Rasterplatte 117 verlaufende erste Führungsplatte 144 sowie eine schräg dazu verlaufende zweite Führungsplatte 145 auf. Der obere Bereich 120 sowie die Nase 121 des vertikalen Teils 115 des Haltebügels 103 sind bei dieser Ausführungsform mit keiner Feder versehen. Der Haltebügel wird schräg in den Führungskanal 143 eingeführt, indem er an der Führungsplatte 145 anliegt, wobei er so weit nach oben geschoben wird, bis der Absatz 113 des Kunststoffteiles 141 sowie der horizontale Teil 116 des Haltebügels 103 das Ende 146 des Ziegels 142 zangenförmig umfassen, und dann gekippt und wenn nötig noch nach oben geschoben, bis die Nase 121 zwischen zwei Rasterzähnen 118 eingreift. Ebenfalls wie beim Ausführungsbeispiel gemäss den Fig. 1 bis 4 gilt auch bei diesem Ausführungsbeispiel, dass je grösser der Schneedruck auf den Schneerückhalteteil 110 ist, umso stärker wird die Klemmwirkung der das Ziegelende 146 zangenförmig umfassenden Teile des Schneehalters, nämlich des Absatzes 113 sowie des horizontalen Teils 116 und des Ansatzes 106 des Haltebügels 103, auf den Ziegel 142.FIG. 5 shows a side view, partly in section, of a second exemplary embodiment of a snow holder 140. The same parts as in the first embodiment are provided with the same reference numerals in this second embodiment. This exemplary embodiment likewise comprises an integrated plastic part 141 and a holding bracket 103. The holding bracket 103 also has a vertical part 115, a horizontal part 116 and an extension 106 bent from the horizontal part 116. In this second exemplary embodiment, the use of the snow holder is shown for a concrete tile 142, in which case the shoulder 113 of the plastic part 141, the horizontal part 116 and the shoulder 106 of the holding bracket 103 encompass the lower end 146 of the concrete tile as seen from the roof. The second exemplary embodiment shown in FIG. 5 would of course also be applicable to clay bricks, as shown in FIG. 1, in which case the step 104 would rest on the brick. The plastic part 141 likewise comprises a grid plate 117 with grid teeth 118. The guide channel 143 for the holding bracket 103 has a first guide plate 144 running parallel to the grid plate 117 and a second guide plate 145 running obliquely thereto. The upper region 120 and the nose 121 of the vertical part 115 of the holding bracket 103 are not provided with a spring in this embodiment. The bracket is inserted obliquely into the guide channel 143 by abutting the guide plate 145, whereby it is pushed upwards until the shoulder 113 of the plastic part 141 and the horizontal part 116 of the bracket 103 embrace the end 146 of the brick 142 in the form of pliers , and then tilted and, if necessary, pushed upwards until the nose 121 engages between two raster teeth 118. As in the exemplary embodiment according to FIGS. 1 to 4, it also applies in this exemplary embodiment that the greater the snow pressure on the snow retaining part 110, the stronger the clamping effect of the parts of the snow holder comprising the brick end 146, namely the shoulder 113 and the horizontal part Part 116 and the approach 106 of the bracket 103, on the brick 142nd

Die beiden Ausführungsformen gemäss den Fig. 1 bis 5 weisen den Vorteil auf, dass sie für beliebige Dachziegeldicken und -formen verwendet werden können.The two embodiments according to FIGS. 1 to 5 have the advantage that they can be used for any roof tile thickness and shape.

Der erfindungsgemässe Schneehalter kann, wie aus Fig. 1 und 5 ersichtlich ist, sowohl für Tonziegel, die eine grössere Dicke, aber einen etwas schmäleren Absatz 107 am Ende aufweisen, als auch für Betonziegel, die eine geringere Dicke, aber einen etwas breiteren Absatz 146 am Ende aufweisen, verwendet werden. Dies wird erzielt, indem anschliessend an den Schneerückhalteteil 110 zwei abgestufte Absätze 104 und 113 vorgesehen sind.The snow holder according to the invention can, as can be seen from FIGS. 1 and 5, both for clay bricks which have a greater thickness but a somewhat narrower heel 107 at the end, and for concrete bricks which have a smaller thickness but a somewhat wider heel 146 have at the end, are used. This is achieved in that two stepped shoulders 104 and 113 are then provided on the snow retaining part 110.

Durch den Druck des Schnees auf den Schneerückhalteteil werden bei allen Ausführungsformen die eine Zange bildenden Arme zusammengedrückt und dabei fest am Ziegel gehalten.By the pressure of the snow on the snow retention part in all embodiments, the arms forming a pair of pliers are pressed together and held firmly on the brick.

Bei einer in der Zeichnung nicht dargestellten Ausführungsform ist der Schneerückhalteteil im Bereich des Auflageteils angeordnet.In one embodiment, not shown in the drawing, the snow retention part is arranged in the region of the support part.
