Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to a device for protecting a rain gutter from contaminants in particular, which is provided with a net-shaped filter pipe for being disposed in a gutter trough of the gutter. Further, the present invention relates to a filter pipe in which the filter pipe is formed to have a slit in a longitudinal direction.

[0002]

BACKGROUND OF THE INVENTION Rain gutters can be filled one after another with leaves and other debris. as a result,
The generated rainwater does not flow slowly. Also, overflow of the rain gutter is observed relatively early. Therefore, keeping leaves and other debris away from the gutters
This is an advantageous means.

German Utility Model No. 921332
As is known from U.S. Pat. No. 5,547,867, a filter pipe with a slit with a net-shaped peripheral surface is inserted into the gutter trough of the gutter. Thus, while the leaves of the tree remain outside the filter pipe, the incoming rainwater flows into the gutter trough and flows inside the gutter trough. Leaves, or the like, are discharged over the filter pipe.

[0004] Solid particles, such as litter, leaves, pollen, and the like, pass through the net surface of the filter pipe and into the gutter trough. If a large amount of water flows through, some particles are entrained and washed out of the gutter trough. The remaining particles are trapped by the net structure of the filter pipe and are thus located in the gutter trough. These residual particles hinder drainage and the derivation of newly coming particles.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to improve a device of the type mentioned at the outset so that the pollutants can be easily discharged and that the gutters have a low possibility of contamination. To provide a device for protection from

[0006]

In order to solve such a problem, according to the configuration of the present invention , a filter pipe is installed in a rain gutter.
The filter located in the gutter trough when it is put in
The pipe section is at least partially
I had it.

[0007]

According to said solution, at least the area of the filter pipe, which is to be located below the gutter trough, has a continuously closed, particularly smooth peripheral surface. I have. Contaminants no longer accumulate on such peripheral surfaces, but rather these contaminants can be washed off along the gutter by the incoming rainwater.

Conventional filter pipes having a continuous net-like surface are formed with slits in the longitudinal direction, and advantageously the longitudinal slits are located at the deepest point of the gutter trough. ing. The device according to the invention may also have a filter pipe with a longitudinal slit. In this case, the edge region separating both sides of the slit is constituted by a closed surface.
Runoff rainwater flows directly along such areas. In this case, providing a closed surface is very effective.

[0009] The filter pipe is elastically deformable. Thereby, it can be fitted to rain gutters of different sizes. The tightening effect of the filter pipe is always maintained. Both edge areas with the obstructed surface,
Can overlap each other. Advantageously, in this case, both edge regions have a tapering cross-section, i.e. these edge regions become progressively thinner toward the free edge. Thus, despite the insertion of the filter pipe, the full depth of the gutter trough can still be used. When these edge areas overlap as described above, the filter pipe can be easily inserted into the gutter trough. because,
This is because the tapered edge regions are easily movable beside each other. Furthermore, no disturbing seams are formed in the area of the overlap.

[0010] The closed edge area is approximately ４ to の of the entire circumference of the filter pipe inserted into the gutter trough.
. Therefore, the main function of the filter pipe, that is, the function of blocking pollutants and allowing rainwater to flow through at the same time, is maintained.

[0011] The net-like region of the filter pipe is composed of a longitudinal strand and a circumferential strand in a general-purpose form. According to the object of the invention, the longitudinal strands of the net-like region of the filter pipe are provided as outwardly projecting webs, in particular webs having different heights. Is formed. This does not mean that the leaves of each tree are located on the net-like surface. Wet and softened wet leaves can also stick to the net-like surface. This is avoided by the web. This facilitates leaf removal by light air motion. These webs can be formed and arranged in different forms depending on the purpose obtained. Thus, webs of different heights can be provided. In the area just above the filter pipe,
The tall web can act as a guide for the flowing rainwater. The laterally oriented web serves as an assembly aid when inserting the filter pipe into the gutter trough, and in some cases also as a locking element. These webs can also be bent radially to have a straight or curved cross section. This allows for an improved water delivery function of the web. The specially deformed or bent web may also serve as a retaining and locking function for the gutter trough or for the adjacent gutter.

Advantageously, these webs are at least 0.5 cm, especially 1 cm, over the circumferential strands.
It has a protrusion of 5 cm, preferably 1 cm to 2 cm. Advantageously, between these protruding webs is provided one or more longitudinal strands with reduced projections or one or more longitudinal strands without reduced projections. ing. In the case of just relatively fine net structures, in this way an easily accessible and easy-to-clean surface is obtained.

It is advantageous if the filter pipe is made of plastic, in particular by extrusion. Therefore, low-cost manufacturing is possible.

The edge region can be injected into a net-like region by coextrusion. The edge area can also be formed by a piece of sheet bonded to the net-like area, in particular by welding. In the same way, protruding longitudinal strands or webs can be manufactured and possibly also connected to other net structures. Advantageously, these webs are high-profile longitudinal strands. Due to these manufacturability features described above, the edge region can be formed from a different material (plastic) than the net-like region.

[0015] Further advantageous embodiments of the invention are described in the dependent claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

The invention is based on the general gutter structure known from German Utility Model No. 9213325, for example. Below the roof 10, a rain gutter 11 is fixed laterally. The rain gutter 11 includes a rain gutter trough 12 held by a holding portion 13 fixed to the roof 10.
have.

While the edge 14 of the gutter trough 12 opposite to the roof 10 is bent outward, the roof-side edge 15 located opposite the edge 14 has an inner side. It is bent toward.

The holding section 13 is a narrow strip.
It extends only through one short section of the overall length of the gutter trough 12 and is connected to the roof 10 at one end 16 and at the other end 17 the gutter trough 12
, Extending below the downwardly bent edge 14.

An elongated filter pipe 18 that is elastically deformable is inserted into the rain gutter trough 12 to change its diameter and to generate a spring preload. The filter pipe 18 itself is shown in FIGS. 1 and 2 and consists of a central net area 19 and edge areas 20, 21 each with a closed, smooth surface, this surface being , Filter pipe 1
8 form a part of the remaining net-shaped peripheral surface. In the net region, the circumferential strand 22 extends in the circumferential direction, and the longitudinal strand 23 extends in the direction of the central longitudinal axis 24 of the filter pipe 18.

In all the embodiments shown, the filter pipe 1
8 is formed so as to have a slit. Rain gutter 11
Depending on the size of the longitudinal slit 25 or the overlapping portion 26 between the closed edge regions 20, 21.
Is produced. These edge regions 20, 2 which are closed
Numerals 1 are arranged corresponding to the sides of the longitudinal slit 25 facing each other. The filter pipe 18 shown in FIG. 1 is inserted into the gutter trough 12 with the longitudinal slit 25 maintaining the shape shown. In this case, the rainwater (depending on the state of the water) flows out via the bottom (not shown) of the gutter trough or the edge region 20,
21 through the closed surface. The possible contaminants are removed together by the escaping water and there is no risk of being deposited in the filter pipe 18.

In the embodiment of FIG. 2, water flows along the surfaces of the closed edge regions 20, 21 which partially overlap each other. To clarify the difference, the left edge region 20 is shaded and the right edge region 21 is shown in black. In practice, both edge regions 20, 2
1 are formed identically to one another and are shown in cross section and similar to FIG. To facilitate overlap, these edge regions 20, 21 are tapered in FIG. 2, ie, these edge regions 20, 21 are
The free edges 27, 28 are formed with a reduced layer thickness.

In FIG. 3, the undeformed filter pipe 18
Are dimensioned as follows, i.e., the two edge regions 20, 21 do not just overlap each other or there is a very narrow longitudinal slit 25. Also in this embodiment, the edge regions 20, 21
Have a layer thickness that decreases towards the edge. By compressing the filter pipe 18, these edge regions 20, 21 can overlap to a greater or lesser extent. At this time, the filter pipe 18
Are elastically preloaded or internally stressed by the tendency of the filter pipe 18 to increase in diameter. By such preloading, the filter pipe 18 can be held in the gutter trough 12.

FIG. 3 shows the advantage of the arrangement of the individual longitudinal strands. Some longitudinal strands are thus formed in a radially enlarged dimension, projecting in a web-like manner according to this dimension and beyond the thickness of the circumferential strand 22. The longitudinal strands thus changed are connected to the web 2
9-33. These webs 29-
33, a longitudinal strand 23 having the same height as the circumferential strand 22 is provided, and the longitudinal strand 23 and the protruding web-like longitudinal strands (webs 29 to 33) are mutually separated. They are provided alternately.

These webs 29-33 are arranged approximately one-third above the entire circumference of the filter pipe 18, and in any case only in the area of the circumference that abuts the gutter trough 12. Is not located.

The webs 29 to 33 have a height of 1 cm to 2 cm, but this height is at least 0,1 cm.
5 cm and up to 5 cm.

FIG. 4 also shows a particularly advantageous point.
FIG. 4 shows only the upper section of the filter pipe 18. In this embodiment, the webs 34-38 are
It is bent or curved in the direction of the roof 10. Rainwater flowing down from the roof 10 is drawn from these webs 34-38 to the filter pipe 18. The illustrated bend prevents or reduces the lateral overflow of the webs 34-38.

The side webs 34, 38 are formed shorter than the upper webs 35, 36, 37. Thereby, the filter pipe 18 can be easily introduced into the rain gutter trough 12 connected to the roof 10 within a predetermined inner width.

FIG. 3 shows a side web 33 on the roof side,
The locking between the gutter trough 12 and the inwardly bent edge 15 is shown. When the filter pipe 18 is inserted, it is pushed into the gutter trough 12 until the lateral web 33 engages behind the edge 15.

The webs 39 to 41 indicated by broken lines in FIG.
Is bent or curved in the opposite direction to the webs 34-38 and is provided selectively with respect to the webs 34-38. With such a configuration, the leaves and the like are more likely to slide down from the roof 10 to the position over the filter pipe 18.

The filter pipe 18 is made entirely of plastic, in particular by extrusion. This also applies to the smooth edge areas 20, 21 and the webs 29-41, which webs 29-41
41 is advantageously integrally formed with the filter pipe 18, but is made of a different plastic than the filter pipe 18. The bent or curved webs 34-41 are the webs 34-4
1 is preformed at the time of manufacture.
