Definitions
- the invention relates to a device for protecting in particular gutters against contamination according to the preamble of claim 1.
- the tubular Abweisgitter is formed by a slotted plastic mesh tube.
- the net tube has longitudinal strands which run in the longitudinal direction of the tubular Abweisgitters and the gutter trough and transversely to the longitudinal direction of the tubular Abweisgitters extending transverse strands.
- the longitudinal and transverse strands are spaced from each other to form the network structure of the net tube.
- the longitudinal strands have a larger cross section than the transverse strands. As a result, the transverse strands are spaced from the gutter trough.
- the from the US Pat. No. 2,533,402 known device is formed of a wire mesh of longitudinal and transverse strands.

- the invention has for its object to provide a device of the type mentioned, which does not impair the drainage from the gutter or at least not appreciably.
- the transverse strands are designed such that they are supported only partially in the gutter trough. It is envisaged that parts or sections or regions of the transverse strands of the tubular Abweisgitters project outwardly and assign adjacent end portions of each outwardly curved portion adjacent longitudinal strands. Between the outermost vertices of the individual curved sections of the transverse strands they are spaced from the inside of the gutter trough. This will release a free drain of water and possibly also small impurities carried along.
- the transverse strands extending transversely to the longitudinal direction of the gutter are at least partially spaced from the interior of the gutter trough, whereby water and also fine contaminants can flow away unhindered under at least parts of the transverse strands in the longitudinal direction of the gutter.
- the drainage of the water from the gutter by the transverse strands is not or at least not significantly affected.
- no small solid particles passing through the tube-like deflector grid into the gutter trough can accumulate in the gutter trough and thereby impair the free flow of water through the gutter.
- each curved portion with the respective longitudinal strand are integrally connected to form the tubular Abweisgitters.
- the transverse strands are around, ie over their entire circumference or their entire length, partially and / or partially arched outwards.
- the transverse strands are spaced from the roof gutter trough, so that channels extending in the longitudinal direction of the gutters, preferably a plurality of parallel and / or spaced channels, between the transverse strands and the inner wall of the gutter trough arise, allowing an unimpeded flow of water and also carried out with the water removal of smaller solid particles from the gutter.
- each transverse strand in one piece despite its partial and / or areawise curvature.
- the cross strands lie only with the farthest outward vertexes of their curvature inside the gutter trough.
- the transverse strands In a preferred embodiment of the transverse strands their curved sections have an epicycloid-like course.
- the cross-sectional planes of the longitudinal strands are at least over part of the circumference of the transverse strands on an imaginary circular path. Outside of this imaginary circular path are located with their vertex outwardly curved portions of the transverse strands, with opposite ends of each arcuate portion lying on the imaginary circular path, in such a way that they meet or cut the longitudinal strands and thereby crossing points between the longitudinal strands and opposite ends of the arcuate portions of the transverse strands.
- the transverse strands and the longitudinal strands are integrally connected to each other at these intersections, in particular fused together, so that at the intersections, the longitudinal strands and the transverse strands are not superimposed, but in a preferably curved crossing plane.
- the intersections are not or at least not appreciably thicker than the transverse and / or longitudinal strands.
- the device shown in the figures serves to protect a gutter 10 against mainly mechanical impurities such as leaves, branches or other solid particles.
- the device has the shape of an elongate tubular Abweisgitters 12 which can be inserted or inserted into a gutter trough 13 of the gutter 10.
- a longitudinal axis of the tubular Abweisgitters 12 extends in the longitudinal direction of the gutter 11 and the gutter trough 13th
- the gutter 11 is attached in a conventional manner at the eaves-side (lower) end of an oblique roof 10 shown schematically in the figure.
- the gutter 11 may also be attached to the edge of a flat roof of another roof.
- the gutter trough 13 of the gutter 11 shown in the figures has an approximately semicircular cross section.
- the gutter 11 may also have a different trough-like cross-section, for example, a box-like cross-section.
- the tubular Abweisgitter 12 of the device is not closed in the embodiments shown, but provided with a longitudinal slot 15 which extends in the longitudinal direction of the gutter 11.
- the diameter of the tubular Abweisgitters 12 change to accommodate different sized, especially in cross-section different gutter troughs 13.
- the longitudinal slot 15 on both sides limiting longitudinal edges 16, 17 of the tubular Abweisgitters 12 slightly spaced from each other to form a gap 18 between the longitudinal edges 16, 17 ( Fig. 1 ).
- the longitudinal edges 16, 17 overlap one another to form an overlapping region 19 located below in the gutter trough 13 (FIG. Fig. 2 ).
- the longitudinal slot 15 and the gap 18 of the tubular Abweisgitters 12 are down in the gutter trough 13, at the lowest point.
- this can be adapted to the diameter of the gutter-like trough 13 by either the gap 18 remains between the longitudinal edges 16, 17 or the overlap region 33 is formed.
- the formed from plastic tubular Abweisgitter 12 can be prepared as a tube by, for example, extrusion, preferably so that the tube in the initial state in the Fig. 1 shown gap 18 between adjacent longitudinal edges 16, 17 has.
- By compressing the tubular Abweisgitter 12 is adaptable to smaller gutters 11 by the longitudinal edges 16, 17 overlap more or less.
- the invention is not only suitable for devices with a longitudinal slot 15 having tubular Abweisgitter 12, but also for devices with a closed mesh or net tube made of plastic, which has no longitudinal slot 15.
- the tube-like deflector grid 12 or a closed grid or network tube for forming the device can also be made of a material other than plastic, for example metallic materials of different types, for example wire or a wire mesh or a wire mesh.
- All longitudinal strands 29 extend at the same distance parallel to each other in the longitudinal direction of the tubular Abweisgitters 12 and thus also in the longitudinal direction of the gutter trough 13 of the gutter 11.
- the transverse strands 30 are parallel even at a uniform distance to each other, but transverse to the longitudinal axis of the tubular Abweisgitters 12 of the gutter trough 13 of the gutter 11. This intersect at intersections 22, the longitudinal strands 29 and transverse strands 30 at right angles.
- the longitudinal strands 29 and the transverse strands 30 are integrally connected to each other by quasi melted together in forming the tubular Abweisgitters 12 made of plastic.
- the distances between adjacent longitudinal strands 29 and adjacent transverse strands 30 are the same in the illustrated tubular Abweisgitter 12, so that between the Longitudinal strands 29 and the cross strands 30 approximately square grid openings 23 arise. It is also conceivable to make the distances between adjacent longitudinal strands 29 and the transverse strands 30 vary in size so that rectangular grid openings are formed. It is also conceivable that the longitudinal strands 29 and the transverse strands 30 intersect at an angle of ⁇ 90 °. Then diamond-shaped Gitteröffnüngen arise.
- the dimensions of the grid openings 23 are selected such that a large part of solid components, in particular leaves and branches, can not fall through the grid openings 23 and thus can be diverted via the gutter 11 with the at least one device inserted therein and the grid openings 23 are not by adding ice for example.
- tubular Abweisgitter 12 of Fig. 1 and 2 all longitudinal strands 29 have a same cross-section, preferably diameter, wherein this cross-section corresponds to that of the transverse strands 30.
- the transverse strands 30 between adjacent longitudinal strands 29 are provided with an outwardly directed curvature, over the entire circumference of the tubular Abweisgitters 12, so not only those parts of the transverse strands 30, which are located in the gutter trough 13, but also those outside the Dachrinnentrogs 13 lie. All in the longitudinal direction of the gutter 11 linearly parallel longitudinal strands 29 have a same diameter and equal distances to each other. With their outer longitudinal lines are all longitudinal strands 29 of the tubular Abweisgitters 12 of Fig. 1 on an imaginary cylindrical casing. In other words, this imaginary envelope surrounds all the longitudinal strands 29 from the outside.
- the outward curvatures of the transverse strands 30 are in the illustrated embodiment ( Fig. 1 and 2 ) formed of aligned arcuate portions 31. All arcuate portions 31 are identical. The middle vertex of each arcuate portion 31 protrudes outward most opposite to the longitudinal strands 29. With this outer vertex all located in the gutter 11 are arcuate portions 31 of all transverse strands 30 on the inside 27 of the gutter trough 13 at. Each arcuate portion 31 is integrally connected at its opposite end portions with adjacent longitudinal strands 29.
- tubular Abweisgitter 12 is inserted into a larger gutter trough 13, so that a gap 18 between the unilaterally free longitudinal strands 29 for forming the longitudinal edges 16, 17 of the tubular Abweisgitters 12 is formed.
- the longitudinal slot 15 of the tubular Abweisgitters 12 is thus bounded by two adjacent longitudinal strands 29 with one-sided missing arcuate sections 31, these two adjacent longitudinal strands 29, the longitudinal edges 16, 17 of the tubular Abweisgitters 12 form.
- the cross sections of the arcuate portions 31 for forming the transverse strand 30 may be as large as the cross sections of the longitudinal strands 29.
- the cross sections of the arcuate portions 31 of the transverse strands 30 are slightly smaller than the cross sections of the longitudinal strands 29.
- the cross sectional areas of the arcuate portions 31 of the transverse strands 30 only half to one quarter of the cross sectional area of the longitudinal strands 29 amount.
- each transverse strand 30 is formed of a plurality of juxtaposed arcuate portions 31 between two longitudinal strands 29, arise in Dachrinnentrog 13 with a small parallel distance adjacent longitudinal channels 32, sufficient to water and smaller particles, such as flowers of plants, unhindered in Let the longitudinal direction of the gutter 11 to drain.
- the Fig. 2 shows the tubular Abweisgitter 12 of Fig. 1 with reduced by elastic compression reduced diameter. That only reduced in diameter tubular deflector 12 is particularly suitable for insertion into smaller gutter troughs 13th
- the overlap region 33 is located at or in the region of the lowest point of the gutter trough 13. This is at the lowest point or in the vicinity of the lowest point of the gutter trough 13 due to the overlap of the outgoing from the longitudinal edge 17 edge region and the underlying, from the other longitudinal edge sixteenth outgoing edge region taking place lifting a at the outgoing edge 17 edge region adjoining portion 34 of the tubular Abweisgitters 12 a partially enlarged gap 35 in the lower region of the gutter trough 13 created. This favors unimpeded outflow of water and also smaller solid particles which have passed through the grid openings 23 into the tubular deflector grid 12, out of the gutter 11.
- the transverse strands 30 and the longitudinal strands 29 are provided with a circular cross-section.
- the invention is not limited thereto.
- the longitudinal strands 29 and the transverse strands 30 can also have other cross sections, for example non-round or even polygonal cross sections.

Die Erfindung betrifft eine Vorrichtung zum Schutz von insbesondere Dachrinnen gegen Verunreinigungen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for protecting in particular gutters against contamination according to the preamble of claim 1.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die den Wasserabfluss aus der Dachrinne nicht oder zumindest nicht nennenswert beeinträchtigt.The invention has for its object to provide a device of the type mentioned, which does not impair the drainage from the gutter or at least not appreciably.
Eine Vorrichtung zur Lösung dieser Aufgabe weist die Merkmale des Anspruchs 1 auf. Demnach sind die Querstränge derart ausgebildet, dass sie sich nur abschnittsweise im Dachrinnentrog abstützen. Dabei ist es vorgesehen, dass Teile bzw. Abschnitte oder Bereiche der Querstränge des rohrartigen Abweisgitters nach außen vorstehen und gegenüberliegende Endbereiche jedes nach außen gewölbten Abschnitts benachbarten Längssträngen zuzuordnen. Zwischen den am weitesten außen liegenden Scheitelpunkten der einzelnen gewölbten Abschnitte der Querstränge sind diese von der Innenseite des Dachrinnentrogs beabstandet. Dadurch lassen Sie einen freien Abfluss von Wasser und gegebenenfalls auch mitgeführter kleiner Verunreinigungen frei. So werden die quer zur Längsrichtung der Dachrinne verlaufenden Querstränge mindestens abschnittsweise vom Inneren des Dachrinnentrogs beabstandet, wodurch Wasser und auch feine Verunreinigungen ungehindert unter mindestens Teilen der Querstränge hinweg in Längsrichtung der Dachrinne abfließen können. Auf diese Weise wird das Abfließen des Wassers aus der Dachrinne durch die Querstränge nicht oder zumindest nicht nennenswert beeinträchtigt. Außerdem können sich keine durch das rohrartige Abweisgitter hindurch in den Dachrinnentrog gelangte kleine Feststoffpartikel im Dachrinnentrog ansammeln und dadurch den freien Durchfluss von Wasser durch die Dachrinne beeinträchtigen.An apparatus for achieving this object has the features of claim 1. Accordingly, the transverse strands are designed such that they are supported only partially in the gutter trough. It is envisaged that parts or sections or regions of the transverse strands of the tubular Abweisgitters project outwardly and assign adjacent end portions of each outwardly curved portion adjacent longitudinal strands. Between the outermost vertices of the individual curved sections of the transverse strands they are spaced from the inside of the gutter trough. This will release a free drain of water and possibly also small impurities carried along. Thus, the transverse strands extending transversely to the longitudinal direction of the gutter are at least partially spaced from the interior of the gutter trough, whereby water and also fine contaminants can flow away unhindered under at least parts of the transverse strands in the longitudinal direction of the gutter. In this way, the drainage of the water from the gutter by the transverse strands is not or at least not significantly affected. In addition, no small solid particles passing through the tube-like deflector grid into the gutter trough can accumulate in the gutter trough and thereby impair the free flow of water through the gutter.
Besonders bevorzugt sind die gegenüberliegenden Endbereiche oder Enden jedes gewölbten Abschnitts mit dem betreffenden Längsstrang einstückig verbunden zur Bildung des rohrartigen Abweisgitters.Particularly preferably, the opposite end portions or ends of each curved portion with the respective longitudinal strand are integrally connected to form the tubular Abweisgitters.
Vorzugsweise sind die Querstränge ringsherum, also über ihren ganzen Umfang bzw. ihre ganze Länge, teil- und/oder bereichsweise nach außen gewölbt. Dadurch bilden die Querstränge mindestens im Bereich des Dachrinnentrogs einen mäanderförmigen, gezackten oder schlangenlinienförmigen Verlauf, wodurch sich die Querstränge nur stellenweise im Dachrinnentrog abstützen. Zwischen den sich im Dachrinnentrog abstützenden Stellen der Querstränge sind die Querstränge infolge ihres bogenförmigen, gezackten oder wellenartigen Verlaufs vom Dachrinnentrog beabstandet, so dass in Längsrichtung der Dachrinnen verlaufende Kanäle, vorzugsweise mehrere parallele und/oder beabstandete Kanäle, zwischen den Quersträngen und der Innenwandung des Dachrinnentrogs entstehen, die einem ungehinderten Wasserablauf und auch einen mit dem Wasser erfolgenden Abtransport kleinerer Feststoffpartikelchen aus der Dachrinne zulassen.Preferably, the transverse strands are around, ie over their entire circumference or their entire length, partially and / or partially arched outwards. This form the Transverse strands at least in the area of the gutter trough a meandering, serrated or serpentine course, whereby the transverse strands are supported only in places in the gutter trough. As a result of their arcuate, serrated or wave-like course, the transverse strands are spaced from the roof gutter trough, so that channels extending in the longitudinal direction of the gutters, preferably a plurality of parallel and / or spaced channels, between the transverse strands and the inner wall of the gutter trough arise, allowing an unimpeded flow of water and also carried out with the water removal of smaller solid particles from the gutter.
Bevorzugt ist es vorgesehen, jeden Querstrang trotz seiner teil- und/oder bereichsweisen Wölbung einstückig auszubilden. Dazu verfügen die Querstränge mindestens im Bereich des Dachrinnentrogs über zwischen benachbarten Längssträngen nach außen gewölbte Abschnitte. Indem zwischen benachbarten Längssträngen sich befindende Abschnitte der Querstränge mindestens im Bereich des Dachrinnentrogs nach außen gewölbt sind, liegen die Querstränge nur noch mit dem am weitesten außen liegenden Scheitelpunkten ihrer Wölbung innen am Dachrinnentrog an.Preferably, it is provided to form each transverse strand in one piece despite its partial and / or areawise curvature. For this purpose, have the transverse strands at least in the region of the gutter trough over adjacent longitudinal strands outwardly curved sections. By curving between adjacent longitudinal strands sections of the transverse strands are arched at least in the region of the gutter trough to the outside, the cross strands lie only with the farthest outward vertexes of their curvature inside the gutter trough.
Bei einer bevorzugten Ausgestaltungsmöglichkeit der Querstränge weisen ihre gewölbten Abschnitte einen epizykloidartigen Verlauf auf. Dabei liegen die Querschnittsebenen der Längsstränge mindestens über einem Teil des Umfangs der Querstränge auf einer gedachten Kreisbahn. Außen an dieser gedachten Kreisbahn befinden sich die auch mit ihrem Scheitelpunkt nach außen gewölbten Bereiche der Querstränge, wobei gegenüberliegende Enden jedes bogenförmig gewölbten Abschnitts auf der gedachten Kreisbahn liegen, und zwar so, dass sie die Längsstränge treffen bzw. schneiden und dadurch Kreuzungsstellen zwischen den Längssträngen und gegenüberliegenden Enden der bogenförmigen Abschnitte der Querstränge bilden. Bei aus Kunststoff gebildeten Abweisgittern sind an diesen Kreuzungsstellen die Querstränge und die Längsstränge einstückig miteinander verbunden, insbesondere miteinander verschmolzen, so dass an den Kreuzungsstellen die Längsstränge und die Querstränge nicht übereinanderliegen, sondern in einer vorzugsweise gewölbten Kreuzungsebene. Dadurch sind die Kreuzungsstellen nicht oder zumindest nicht nennenswert dicker als die Quer- und/oder Längsstränge.In a preferred embodiment of the transverse strands their curved sections have an epicycloid-like course. The cross-sectional planes of the longitudinal strands are at least over part of the circumference of the transverse strands on an imaginary circular path. Outside of this imaginary circular path are located with their vertex outwardly curved portions of the transverse strands, with opposite ends of each arcuate portion lying on the imaginary circular path, in such a way that they meet or cut the longitudinal strands and thereby crossing points between the longitudinal strands and opposite ends of the arcuate portions of the transverse strands. In deflector grids formed of plastic, the transverse strands and the longitudinal strands are integrally connected to each other at these intersections, in particular fused together, so that at the intersections, the longitudinal strands and the transverse strands are not superimposed, but in a preferably curved crossing plane. As a result, the intersections are not or at least not appreciably thicker than the transverse and / or longitudinal strands.

Die in den Figuren gezeigte Vorrichtung dient zum Schutz einer Dachrinne 10 gegen vor allem mechanische Verunreinigungen wie zum Beispiel Laub, Äste oder sonstige Feststoffpartikel. Die Vorrichtung weist die Gestalt eines länglichen rohrartigen Abweisgitters 12 auf, das in einen Dachrinnentrog 13 der Dachrinne 10 einlegbar bzw. einsetzbar ist. Dabei erstreckt sich eine Längsachse des rohrartigen Abweisgitters 12 in Längsrichtung der Dachrinne 11 und auch des Dachrinnentrogs 13.The device shown in the figures serves to protect a
Die Dachrinne 11 ist in an sich üblicher Weise am traufseitigen (unteren) Ende eines in der Figur schematisch dargestellten schrägen Dachs 10 befestigt. Die Dachrinne 11 kann auch am Rand eines Flachdachs eines sonstigen Dachs befestigt sein.The
Der Dachrinnentrog 13 der in den Figuren gezeigten Dachrinne 11 verfügt über einen etwa halbkreisförmigen Querschnitt. Die Dachrinne 11 kann aber auch über einen andersartigen wannenartigen Querschnitt verfügen, beispielsweise einen kastenartigen Querschnitt.The
Durch mehrere mit Abstand in Längsrichtung des Dachrinnentrogs 13 hintereinanderliegende Halter 14 ist der Dachrinnentrog 13 der Dachrinne 11 mit beispielsweise der Unterseite des traufartigen Endes des Dachs 10 verbunden.By several spaced apart in the longitudinal direction of the
Das rohrartige Abweisgitter 12 der Vorrichtung ist bei den gezeigten Ausführungsbeispielen nicht geschlossen, sondern mit einem Längsschlitz 15 versehen, der in Längsrichtung der Dachrinne 11 verläuft. Dadurch lässt sich der Durchmesser des rohrartigen Abweisgitters 12 verändern zur Anpassung unterschiedlich großer, insbesondere im Querschnitt unterschiedlicher Dachrinnentröge 13. Bei größeren Dachrinnentrögen 13 sind die den Längsschlitz 15 beidseitigen begrenzenden Längsränder 16, 17 des rohrartigen Abweisgitters 12 etwas voneinander beabstandet zur Bildung eines Spalts 18 zwischen den Längsrändern 16, 17 (
Das aus Kunststoff gebildete rohrartige Abweisgitter 12 kann als Rohr durch beispielsweise Extrudieren hergestellt werden, und zwar vorzugsweise so, dass das Rohr im Ausgangszustand den in der
Die Erfindung eignet sich aber nicht nur für Vorrichtungen mit einem einen Längsschlitz 15 aufweisenden rohrartigen Abweisgitter 12, sondern auch für Vorrichtungen mit einem geschlossenen Gitter- bzw. Netzrohr aus Kunststoff, das über keinen Längsschlitz 15 verfügt.However, the invention is not only suitable for devices with a longitudinal slot 15 having tubular Abweisgitter 12, but also for devices with a closed mesh or net tube made of plastic, which has no longitudinal slot 15.
Das rohrartige Abweisgitter 12 oder ein geschlossenes Gitter- oder Netzrohr zur Bildung der Vorrichtung kann gegebenenfalls auch aus einem anderen Material als Kunststoff hergestellt sein, beispielsweise aus metallischen Materialien unterschiedlicher Art, beispielsweise aus Draht bzw. einem Drahtgitter oder einem Drahtnetz.If appropriate, the tube-
Das rohrartige Abweisgitter 12 verfügt über vorzugsweise geradlinige Längsstränge 29 und Querstränge 30. Alle Längsstränge 29 verlaufen mit gleichem Abstand parallel zueinander in Längsrichtung des rohrartigen Abweisgitters 12 und somit auch in Längsrichtung des Dachrinnentrogs 13 der Dachrinne 11. Die Querstränge 30 verlaufen auch mit gleichmäßigem Abstand parallel zueinander, aber quer zur Längsachse des rohrartigen Abweisgitters 12 des Dachrinnentrogs 13 der Dachrinne 11. Dadurch schneiden sich an Kreuzungsstellen 22 die Längsstränge 29 und Querstränge 30 rechtwinklig. An den Kreuzungsstellen 22 sind die Längsstränge 29 und die Querstränge 30 einstückig miteinander verbunden, indem sie bei Bildung des rohrartigen Abweisgitters 12 aus Kunststoff quasi zusammengeschmolzen sind.All
Die Abstände zwischen benachbarten Längssträngen 29 und benachbarten Quersträngen 30 sind beim gezeigten rohrartigen Abweisgitter 12 gleich, so dass zwischen den Längssträngen 29 und den Quersträngen 30 etwa quadratische Gitteröffnungen 23 entstehen. Es ist auch denkbar, die Abstände zwischen benachbarten Längssträngen 29 und den Quersträngen 30 unterschiedlich groß zu machen, so dass rechteckige Gitteröffnungen entstehen. Ebenso ist es denkbar, dass sich die Längsstränge 29 und die Querstränge 30 unter einem Winkel von < 90°kreuzen. Dann entstehen rautenartige Gitteröffnüngen. Die Abmessungen der Gitteröffnungen 23 sind so gewählt, dass ein Großteil fester Bestandteile, insbesondere Blätter und Äste, nicht durch die Gitteröffnungen 23 hindurchfallen können und somit über die Dachrinne 11 mit der mindestens einen darin eingelegten Vorrichtung hinweg ableitbar sind und sich die Gitteröffnungen 23 auch nicht durch zum Beispiel Eisbildung zusetzen können.The distances between adjacent

Alle in Längsrichtung der Dachrinne 11 geradlinig parallel verlaufenden Längsstränge 29 weisen einen gleichen Durchmesser und gleiche Abstände zueinander auf. Mit ihren äußeren Längslinien liegen alle Längsstränge 29 des rohrartigen Abweisgitters 12 der
