Definitions

• the present invention relates to a roof cove ⁇ ring or its extension as defined in the preamble claim 1.
• Rain water troughs need to be protected with a suitable screen in buildings located on a site with trees near the building. Leaves, twigs, needles and other undesirable material are washed by rain from the roof into the water trough, which is thus filled and blocked so that water cannot flow in the trough.
• the water and rubbish freeze in the water trough, thus completely preventing water flow in the trough. Therefore, the water trough must be cleaned several times a year.
• the problem is that cleaning the troughs is a laborious and difficult job, which is why the cleaning of the troughs is rea ⁇ dily neglected, in which case the leaf material gets composted in the trough, the trough becomes full and the water no longer flows along the trough into the rain pipe and down through the pipe, but directly over the trough to the ground.
• a known solution is to use a net mounted on top of the water trough.
• a net is rela- tively easy to install, but it gets blocked by leaves and other material falling onto it.
• the wa ⁇ ter flowing into the trough again carries leaves and rubbish from the roof onto the net, thus further in ⁇ creasing the mass of material on the net.
• the material remains on the net and gets com ⁇ posted, thus blocking the net, so that water flowing down the roof will pass over the net to the ground instead of flowing into the water trough.
• a perforated plate placed above the trough parallel to the roofing guides the leaves and other rubbish so that they pass over the trough, but due to surface tension the water also flows down over the trough to the ground instead of flowing through the perforations into the trough.
• the object of the present invention is to eliminate the problems referred to above.
• a specific object of the present invention is to produce a new type of roof covering or its extension which allows the above-mentioned problems to be eliminated.
• a further object of the present invention is to produce a roof covering or its extension which is easy to retrofit as an addition to a finished roof co ⁇ vering and water trough to protect the water trough from leaves and other rubbish.
• the roof covering of the invention or its ex ⁇ tension, arranged on the eave of a sloped roof to ex ⁇ tend above the water trough, comprises a number of ho- les provided with water guides for guiding the water into the trough.
• the roof covering or its extension may be manufactured e.g. from a metal sheet or the li- ke.
• the roof covering may also be manufactured from brick or other corresponding materi ⁇ al, in which case the extension of the roof covering that extends over the water trough is still made of a sheet-like material.
• the roof covering or its extension is so dis ⁇ posed relative to the water trough that the holes lie above the water trough.
• the roof covering or its extension is so made that it extends over the roof edge far enough to cover the water trough at ⁇ tached to the verge board.
• the invention has the advantage that the roof covering or its extension in itself forms a sliding surface over the water trough at the eave, ensuring that the material falling down from trees and sliding along the roof covering will not stop over the trough but continues sliding over it while the water flows through the holes into the trough.
• a further advantage as compared with prior art is that, due to the water guides, even water flo ⁇ wing at a high rate will be guided through the holes into the trough and will not flow across them.
• the water guide is a ton ⁇ gue-shaped element disposed below the hole and having a trough-like shape in the area of the hole.
• the water guide is produced by making a cut in the roof covering and stamping the blank left from the ho ⁇ le into a suitable shape. The cut is so made that the blank will remain connected to the roof covering by one edge. This allows a simple and fast manufacture of the roof covering.
• the holes are disposed in an interlapping pattern relative to each other so that water flowing down the roof covering is guided into one of the holes.
• the holes are made into a suitable size and shape, e.g. an elongated shape, so that even water running at a high rate will be guided into the hole while leaves and rubbish will flow over the roof covering.
• An elongated hole need not necessarily be provided with a water guide because a suitably shaped hole will reduce the surface tension of the water, thus contributing towards guiding the water into the hole.
• the water trough is formed from the roof covering or its extension by bending the end of the roof covering or its extension that extends over the roof edge into a tubular shape. This makes it possible to install both the roof cove ⁇ ring or its extension and the water trough at the same time. Moreover, mounting a verge board becomes super ⁇ fluous because the water trough is a tubular element and also acts as a verge board.
• the roof covering pre ⁇ ferably comprises fixing elements for the mounting of the roof covering.
• Fig. 1 presents a top view of a roof covering or its extension as provided by the invention
• Fig. 2 presents a side view of the embodiment shown in Fig. 1; and Fig. 3 presents another embodiment in side view.
• the roof covering 1 presented in Fig. 1 is provided with a number of holes 3 arranged in two rows in an interlapping pattern so that water flowing down the roof will pass through one of the holes.
• the roof covering or its extension may be e.g. a brick- patterned metal sheet or equivalent.
• Fig. 2 shows the structure of Fig. 1 in side view.
• the structure furt ⁇ her comprises a water guide 2, which is made by sha- ping from the sheet portion left over in connection with the cutting of the hole 3.
• the roof covering 1 or its extension la is mounted on a sloped roof 5 so that it extends over the water trough 5.
• Fig. 2 the roof covering 1 or its extension la is shown as sectioned along secti ⁇ on line II-II in Fig. 1.
• Fig. 3 presents another embodiment of the roof covering.
• the extension la of the roof covering is also used to form a water trough 4 by bending one end of the extension of the roof co ⁇ vering into a tubular shape.
• the extension la of the roof covering is attached by means of fixing elements 6 to the underside of the roof covering 1 and to the roof structure 5.
• the fixing elements used may be any conventional fixing elements, such as screws or nails.
• the roof cove ⁇ ring presented in Fig. 2 can also be formed by adding, according to the invention, an extension la of the roof covering of a suitable length to the existing roof covering, e.g. under it, so that the additional part together with the existing roof covering 1 will form a roof covering assembly as provided by the in- vention.
