Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Schutz einer Dachrinne gegen Verunreinigungen gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for protecting a gutter against Impurities according to the preamble of claim 1.
Dachrinnen können durch Laub und andere Verunreinigungen nach und nach ausgefüllt werden. In der Folge fließt das anfallende Regenwasser nur noch zögernd ab. Auch ist schneller ein Überlauf der Regenrinnen zu beobachten. Es sind deshalb Maßnahmen von Vorteil, die Laub und andere Verunreinigungen aus der Regenrinne fernhalten.Gutters can gradually fill with leaves and other contaminants become. As a result, the accumulated rainwater flows only hesitantly from. Also is faster to watch an overflow of the gutters. It is therefore measures of Advantage that keep leaves and other contaminants out of the gutter.
Aus der DE 92 13 325 U, der DE 90 06 981 U und der DE 17 59 441 A ist es bekannt, in den Dachrinnentrog einer Dachrinne ein geschlitztes Filterrohr mit einer netzförmigen oder gelochten Mantelfläche einzulegen. Dadurch bleibt das Laub außen auf dem Filterrohr, während das anfallende Regenwasser in den Dachrinnentrog hineinläuft und innerhalb desselben abfließt. Das Laub oder dergleichen wird über das Filterrohr abgeführt.From DE 92 13 325 U, DE 90 06 981 U and DE 17 59 441 A it is known in the gutter trough of a gutter a slotted filter tube with a net-shaped or perforated jacket surface. This leaves the leaves on the outside Filter tube while the resulting rainwater runs into the gutter trough and flows within it. The foliage or the like is over the filter tube dissipated.
Feste Teilchen, z. B. Staubklumpen, Laubkrümel, Blütenstaub oder dergleichen, gelangen durch die Netzoberfläche oder die Lochung des Filterrohres in den Dachrinnentrog hinein. Bei ausreichendem Wasserdurchfluß werden einige Teilchen mitgerissen und aus dem Dachrinnentrog herausgespült. Andere Teilchen bleiben in der Netzstruktur oder Löchern des Filterrohres hängen und damit im Dachrinnentrog liegen. Sie hemmen den Wasserablauf und die Abfuhr neu hinzukommender Teilchen.Solid particles, eg. As dust clumps, leaves crumbs, pollen or the like, get through the net surface or the perforation of the filter tube into the gutter trough. With sufficient water flow some particles are entrained and from the Rinsed gutter trough. Other particles remain in the mesh structure or holes hang the filter tube and thus lie in the gutter trough. They inhibit that Water drainage and the removal of newly added particles.
Der Erfindung liegt nun die Aufgabe zugrunde, die Vorrichtung der eingangs genannten Art weiter zu verbessern, durch Verringerung der Verschmutzungsanfälligkeit und zur Erleichterung des Austrags von Verschmutzungen. The invention is based on the object, the device of the aforementioned To further improve its nature, by reducing the susceptibility to pollution and to Facilitating the discharge of contaminants.
Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung gemäß den Merkmalen des Anspruchs 1 gelöst. Demnach weist mindestens ein im Dachrinnentrog zu liegen kommender Bereich des Füterrohres wenigstens eine durchgehend geschlossene, insbesondere glatte, Mantelfläche auf, die an einen Netzbereich des Filterrohrs angrenzt. Schmutzteilchen lagern sich auf dieser Oberfläche nicht mehr ab, sondern können von dem anfallenden Regenwasser entlang der Dachrinne fortgespült werden.According to the invention the object is achieved by a device according to the features of Claim 1 solved. Accordingly, at least one to lie in the gutter trough Coming range of Füterrohres at least one continuously closed, in particular smooth, circumferential surface adjacent to a mesh area of the filter tube. Dirt particles are no longer deposited on this surface but can be removed from the accumulated rainwater along the gutter be washed away.
Das herkömmliche und eine durchgehend netzförmige Oberfläche aus üblicherweise Längssträngen und Umfangssträngen aufweisende Filterrohr kann in Längsrichtung geschlitzt ausgebildet sein, wobei der Längsschlitz vorzugsweise im tiefsten Punkt des Dachrinnentrogs zu liegen kommt. Auch die erfindungsgemäße Vorrichtung kann ein Filterrohr mit Längsschlitz aufweisen. In diesem Fall sind die an den Schlitz beidseitig angrenzenden Randbereiche mit geschlossener Oberfläche ausgeführt. Gerade an diesen Bereichen läuft das abfließende Regenwasser entlang. Das Vorsehen einer geschlossenen Oberfläche ist hier besonders effektiv. Das Filterrohr ist elastisch verformbar. Dadurch kann eine Anpassung an unterschiedlich große Dachrinnen erfolgen. Der Klemmeffekt des Filterrohres bleibt stets erhalten. Die Randbereiche mit geschlossener Oberfläche können einander überlappen. Vorzugsweise weisen dann die Randbereiche einen spitz auslaufenden Querschnitt auf, das heißt sie werden zum freien Rand hin dünner. Auf diese Weise wird trotz eingelegtem Filterrohr weiterhin die voll Tiefe des Dachrinnentroges genutzt. Bei vorgesehener Überlappung der Randbereiche kann das Filterrohr einfacher in den Dachrinnentrog eingelegt werden, da die spitzen Randbereiche leicht aneinander vorbei bewegbar sind. Außerdem entsteht im Bereich der Überlappung keine störende Naht.The conventional and a continuous reticulated surface usually Longitudinal strands and circumferential strands filter tube can in the longitudinal direction be formed slotted, wherein the longitudinal slot preferably in the lowest point of the Gutter troughs come to rest. The device according to the invention can also be Have filter tube with longitudinal slot. In this case, they are on both sides of the slot adjacent edge areas with closed surface executed. Especially at this Areas runs down the runoff rainwater. The provision of a closed surface is particularly effective here. The filter tube is elastically deformable. This allows an adaptation to differently sized gutters. Of the Clamping effect of the filter tube is always maintained. The border areas with closed Surface can overlap each other. Preferably then have the edge regions a pointed expiring cross-section, that is, they are the free edge thinner. In this way, despite the inserted filter tube continues to full depth of Gutter trough used. In intended overlap of the edge areas, the Filter tube easier to be inserted into the gutter trough, as the pointed edge areas easy to move past each other. Moreover arises in the area of overlap no annoying seam.
Die geschlossenen Randbereiche erstrecken sich etwa über ¼ bis ½ des Gesamtumfangs des in den Dachrinnentrog eingelegten Filterrohres. Die Hauptfunktion des Filterrohres, das Durchlassen des Regenwassers bei gleichzeitigem Abhalten von Verunreinigungen, bleibt somit erhalten.The closed edge areas extend approximately ¼ to ½ of the total circumference of the inserted into the gutter trough filter tube. The main function of the filter tube, the passage of rainwater while keeping away contaminants, is thus preserved.
Gemäß einer bevorzugten Weiterbildung der Erfindung sind die Längsstränge netzförmiger Bereiche des Filterrohres als nach außen überstehende Stege ausgebildet, insbesondere Stege unterschiedlicher Höhe. Dadurch kommen einzelne Blätter nicht auf der netzförmigen Oberfläche zu liegen. Gerade nasses, durchgeweichtes Laub kann auch auf der netzförmigen Oberfläche haften bleiben. Dies wird durch die vorgesehenen Stege vermieden. Der Abtrag von Blättern durch leichte Luftbewegungen wird dadurch begünstigt. Je nach angestrebtem Zweck können die Stege in unterschiedlicher Weise ausgebildet und angeordnet sein. Gerade im oberen Bereich des Filterrohres können höhere Stege als Führungen für das anfallende Regenwasser wirken. Zur Seite gerichtete Stege können als Montagehilfe beim Einlegen des Filterrohres in den Dachrinnentrog dienen, gegebenenfalls auch als Rastelement. Auch können die Stege gegenüber der radialen Richtung abgewinkelt sein, mit geradem oder gebogenem Querschnitt. Dadurch ist eine verbesserte Wasserleitfunktion der Stege möglich. Auch können speziell verformte bzw. abgewinkelte Stege Halte- und Rastfunktionen in Verbindung mit dem Dachrinnentrog oder der benachbarten Dachtraufe übernehmen.According to a preferred embodiment of the invention, the longitudinal strands net-shaped areas of the filter tube designed as outwardly projecting webs, especially webs of different heights. As a result, individual leaves do not come up the net-shaped surface to lie. Just wet, soaked foliage can too stick to the reticulated surface. This is through the provided webs avoided. The removal of leaves by light air movements is characterized favored. Depending on the desired purpose, the webs in different ways be formed and arranged. Especially in the upper part of the filter tube can higher webs act as guides for the accumulated rainwater. Directed to the side Webs can be used as an assembly aid when inserting the filter tube in the gutter trough serve, optionally also as a locking element. Also, the webs opposite be angled in the radial direction, with straight or curved cross-section. This is an improved Wasserleitfunktion the webs possible. Also, specially deformed or Angled webs holding and locking functions in conjunction with take over the gutter trough or the neighboring eaves.
Vorzugsweise weisen die Stege einen Überstand über die Umfangsstränge von mindestens 0,5 cm insbesondere 1 cm bis 5 cm, vorzugsweise 1 cm bis 2 cm auf. Zwischen überstehenden Stegen sind vorzugsweise ein oder mehrere Längsstränge ohne oder mit verringertem Überstand vorgesehen. Gerade bei einer feineren Netzstruktur wird auf diese Weise eine einfache zugängliche und leicht zu reinigende Oberfläche erzielt.Preferably, the webs have a projection over the peripheral strands of at least 0.5 cm, in particular 1 cm to 5 cm, preferably 1 cm to 2 cm on. Between protruding ridges are preferably one or more longitudinal strands with or without reduced Supernatant provided. Especially with a finer network structure This will be an easy accessible and accessible way easy to clean surface achieved.
Vorteilhafterweise ist das Filterrohr aus Kunststoff, insbesondere durch Extrusion, hergestellt. Eine kostengünstige Fertigung ist so möglich.Advantageously, the filter tube made of plastic, in particular by extrusion, produced. An inexpensive Manufacturing is possible.
Die Randbereiche können durch Koextrusion an die netzförmigen Bereiche angespritzt sein. Auch können die Randbereiche durch mit den netzförmigen Bereichen verbundene, insbesondere angeschweißte Folienstücke gebildet sein. In derselben Weise können auch die überstehenden Längsstränge bzw. Stege hergestellt und gegebenenfalls mit der übrigen Netzstruktur verbunden sein. Vorzugsweise sind die Stege erhöht ausgebildete Längsstränge. Die genannten Herstellungsmöglichkeiten lassen es zu, die Randbereiche aus einem anderen Material (Kunststoff) zu bilden als die netzförmigen Bereiche.The edge areas can be coextruded to the net shape Be splashed areas. Also, the border areas can through connected to the reticulated areas, in particular welded Be formed film pieces. In the same way also the protruding longitudinal strands or webs can be produced and optionally with the rest of the network structure be connected. Preferably, the webs are formed increased Longitudinal strands. The mentioned production possibilities let it to, the edge areas of another material (plastic) too form as the reticulated areas.

Es wird ausgegangen von einer üblichen Dachrinnenkonstruktion
wie beispielsweise in der DE 92 13 325 01 oder DE 90 06 981 U gezeigt. Unter einem
Dach 10 ist seitlich eine Dachrinne 11 befestigt. Diese weist
einen Dachrinnentrog 12 auf, der von am Dach befestigten Haltern
13 gehalten ist.It is based on a common gutter construction
as shown for example in DE 92 13 325 01 or DE 90 06 981 U. Under a
Ein dem Dach 10 abgewandter Rand 14 des Dachrinnentrogs 12 ist
auswärts gebogen, während ein hierzu gegenüberliegender, dachseitiger
Rand 15 einwärts gebogen ist.A
Der Halter 13 erstreckt sich als schmaler Streifen naturgemäß
nur über einen kurzen Abschnitt der Länge des Dachrinnentroges
12, ist an einem Ende 16 mit dem Dach 10 verbunden und erstreckt
sich mit dem anderen Ende 17 bis unter den abwärts gebogenen
Rand 14 des Dachrinnentroges 12.The
In den Dachrinnentrog 12 ist ein längliches Filterrohr 18 eingelegt,
das zur Durchmesseränderung und zur Erzeugung einer
Federvorspannung elastisch verformbar ist. Das Filterrohr 18
allein ist in den Fig. 1 und 2 gezeigt und besteht aus einem
mittleren Netzbereich 19 und Randbereichen 20, 21 mit jeweils
geschlossener, glatter Oberfläche, die einen Teil der im
übrigen netzartigen Mantelfläche des Filterrohres 18 bildet. Im
Netzbereich verlaufen Umfangsstränge 22 in Umfangsrichtung und
Längsstränge 23 in Richtung einer Längsmittelachse 24 des
Filterrohres 18.In the
In allen gezeigten Ausführungsformen ist das Filterrohr 18 geschlitzt
ausgebildet. Je nach Größe der Dachrinne 11 ist
zwischen den geschlossenen Randbereichen 20, 21 ein Längsschlitz
25 oder eine Überlappung 26 vorhanden. Die
geschlossenen Randbereiche 20, 21 sind gegenüberliegenden
Seiten des Längsschlitzes 25 zugeordnet. Das Filterrohr in der
Ausführung gemäß Fig. 1 wird so in den Dachrinnentrog 12 eingelegt,
daß der Längsschlitz 25 in der gezeigten Form erhalten
bleibt. Das Regenwasser läuft dann über den (nicht gezeigten)
Boden des Dachrinnentroges und die geschlossenen Oberflächen
der Randbereiche 20, 21 ab (je nach Wasserstand). Eventuelle
Verunreinigungen werden durch das abfließende Wasser mitgerissen
und können sich im Filterrohr 18 nicht ablagern.In all embodiments shown, the
In der Ausführung gemäß Fig. 2 läuft das Wasser auf den Oberflächen
der geschlossenen und einander teilweise überlappenden
Randbereiche 20, 21. Zur besseren Unterscheidbarkeit ist der
linke Randbereich schraffiert und der rechte geschwärzt dargestellt.
Tatsächlich sind beide gleichermaßen ausgebildet und
geschnitten dargestellt, und zwar ebenso in Fig. 1. Zur Erleichterung
der Überlappung laufen die Randbereiche 20, 21 in
Fig. 2 spitz zu, das heißt sie sind zu den freien Rändern 27,
28 hin mit abnehmender Dicke ausgebildet.In the embodiment according to FIG. 2, the water runs on the surfaces
the closed and partially overlapping one another
In Fig. 3 ist das unverformte Filterrohr 18 so bemessen, daß
die Randbereiche 20, 21 einander gerade nicht überlappen bzw.
ein nur schmaler Längsschlitz 25 vorhanden ist. Auch hier
weisen die Randbereiche 20, 21 zu den Rändern hin abnehmende
Dicken auf. Durch ein Zusammendrücken des Filterrohres 18
können die Randbereiche 20, 21 mehr oder weniger stark
überlappen. Dabei erhält das Filterrohr 18 eine elastische
Vorspannung bzw. Eigenspannung im Sinne der Neigung des
Filterrohres 18, seinen Durchmesser zu vergrößern. Diese
Vorspannung sorgt auch für einen Halt des Filterrohres 18 im
Dachrinnentrog 12.In Fig. 3, the
Eine Besonderheit in Fig. 3 ist die Gestaltung einzelner Längsstränge.
Einige sind nämlich mit in radialer Richtung
vergrößerter Abmessung und demnach stegartig und über die
Stärke der Umfangsstränge 22 hinausstehend ausgebildet. Die
derart abgewandelten Längsstränge sind als Stege 29 bis 33 bezeichnet.
Zwischen diesen sind Längsstränge 23 mit der Höhe der
Umfangsstränge 22 vorgesehen, und zwar jeweils abwechselnd ein
Längsstrang 23 und ein stegartig überhöhter Längsstrang (Stege
29 bis 33).A special feature in Fig. 3 is the design of individual longitudinal strands.
Some are in the radial direction
enlarged dimension and therefore web-like and over the
Thickness of the
Die Stege 29 bis 33 sind etwa im oberen Drittel des Gesamtumfangs
des Filterrohres 18 angeordnet, jedenfalls nur in nicht
am Dachrinnentrog 12 anliegenden Umfangsbereichen.The
Die Stege 29 bis 33 weisen eine Höhe von 1 cm bis 2 cm auf,
mindestens jedoch 0,5 cm und bis zu 5 cm.The
Eine Besonderheit ergibt sich noch anhand der Fig. 4. Dort ist
nur der obere Abschnitt des Filterrohres 18 gezeigt. Die Stege
34 bis 38 sind hier abgewinkelt bzw. gekrümmt ausgebildet und
zwar in Richtung auf das Dach 10. Das vom Dach 10
herabströmende Regenwasser wird von den Stegen 34 bis 38 auf
dem Filterrohr 18 zurückgehalten. Die gezeigte Krümmung verhindert
oder reduziert ein seitliches Überfließen der Stege 34 bis
38.A peculiarity still results from the Fig. 4. There is
only the upper portion of the
Die seitlichen Stege 34 und 38 sind kürzer ausgebildet als die
oberen Stege 35, 36 und 37. Dadurch ist ein einfacheres Einführen
des Filterrohres 18 in die vorgegebene lichte Weite des
Dachrinnentroges 12 in Verbindung mit dem Dach 10 gegeben.The
Fig. 3 zeigt eine Rastung zwischen dem dachseitigen, seitlichen
Steg 33 und dem einwärts gebogenen Rand 15 des Dachrinnentroges
12. Beim Einlegen des Filterrohres 18 wird dieses so weit in
den Dachrinnentrog eingedrückt, bis der seitliche Steg 33
hinter den Rand 15 greift.Fig. 3 shows a detent between the roof side,
Die in Fig. 4 schraffiert gezeichneten Stege 39 bis 41 weisen
eine Abwinkelung oder Krümmung entgegengesetzt den Stegen 34
bis 38 auf und können alternativ zu diesen vorgesehen sein.
Diese Ausführung erleichtert das Abrutschen von Blattwerk vom
Dach 10 bis über das Filterrohr 18.The hatched in Fig. 4 drawn
Das Filterrohr 18 ist vollständig aus Kunststoff hergestellt,
insbesondere durch Extrusion. Dies gilt auch für die glatten
Randbereiche 20, 21 und die Stege 29 bis 41, die vorzugsweise
einstückig mit dem Filterrohr 18 verbunden sind, aber aus
unterschiedlichen Kunststoffen bestehen können. Die abgewinkelten

- Device for protecting a roof gutter (11) against fouling, the device comprising a lattice-shaped, water-permeable filter pipe (18) for arrangement in a trough (12) of the gutter (11), the filter pipe (18) having a lattice region (19) consisting of circumferential strands (22) and longitudinal strands (23) and being provided with a longitudinal slit (25) extending in the longitudinal direction of the filter pipe (18), characterized in that at least part of a region of the filter pipe (18) that is to be arranged in the gutter trough (12) has at least one continuous lateral surface which adjoins the lattice region (19) of the filter pipe (18).
- Device according to Claim 1, characterized in that marginal regions (20, 21) of the lateral surface which extend in the longitudinal direction of the slit filter pipe (18) are smooth.
- Device according to Claim 2, characterized in that the continuous, smooth marginal regions (20, 21) adjoin opposite sides of the longitudinal slit (25) of the filter pipe (18), the continuous marginal regions (20, 21) preferably overlapping one another.
- Device according to Claim 2 or 3, characterized in that the continuous marginal regions (20, 21) extend approximately over ¼ to ½ of the overall circumference of the filter pipe (18) placed in the gutter trough (12) and are preferably designed to run out to a point.
- Device according to one of the preceding claims, characterized in that some longitudinal strands of lattice-shaped regions (19) of the filter pipe (18) are formed as outwardly projecting ribs (29 to 41).
- Device according to Claim 5, characterized in that the outwardly projecting ribs (29 to 41) have a projection over the circumferential strands (22) of at least 0.5 cm, in particular 1 cm to 5 cm, preferably 1 cm to 2 cm.
- Device according to Claim 5, characterized in that one or more longitudinal strands (23), without a projection or with a reduced projection are provided between the longitudinal strands formed as outwardly projecting ribs (29 to 41), with every second longitudinal strand preferably being formed as an outwardly projecting rib (29 to 41).
- Device according to Claim 5, characterized in that longitudinal strands are formed as outwardly projecting ribs (29 to 41) only in an upper region of the overall circumference of the filter pipe (18), in particular only in the region of an upper fifth, quarter or third of the overall circumference.
- Device according to Claim 5, characterized in that the projecting ribs (34 to 41) are deformed or angled away, in particular with a curved or arcuate cross section, with respect to the radial direction.
- Device according to Claim 2, characterized in that the filter pipe (18) is produced from plastic, in particular by extrusion, with the continuous marginal regions (20, 21) preferably being produced from the same material as the lattice-shaped regions (19).
- Device according to Claim 2, characterized in that the marginal regions (20, 21) are injection-moulded onto the lattice-shaped regions (19) by coextrusion, preferably to form the marginal regions (20, 21) from a plastic material other than that used for the lattice-shaped regions (19).
- Device according to Claim 2, characterized in that the marginal regions (20, 21) are formed by sheet sections connected, in particular welded, to the lattice-shaped regions (19).
- Device according to one of the preceding claims, characterized in that the filter pipe (18) has an internal stress such that it tends to increase in diameter to clamp the filter pipe in the gutter (11).
