SEALING FOR ABUTTING EAVES SECTIONS

Abstract: The invention relates to sealing the joint between the ends of subsequent eaves sections (1) by placing a flat section (9) on top of the supporting legs (5) of the eaves sections such that the joint is covered, which flat section with a downward curved edge (10) engages round the end edge (11) of the supporting legs and with a spring lip (13) snaps under the inward extending horizontal leg (4) at the upper edge of the eaves section.

Description: The invention relates to an eaves section which, viewed in cross section, comprises a leg which is in a vertical plane in the erected position, end which is turned inwards at the bottom edge and at the top edge, which in the erected position is at a distance above the roof covering, has an inward-directed, essentially hori­ zontal leg, said vertical leg having between the bottom edge and the top edge a supporting leg which forms an acute angle with the part of the vertical leg lying below it and at its bottom face is provided with one or more vertical ribs or similar supporting means. Such an eaves section is known. These known eaves sections are generally made of a light metal such as aluminium. They must be capable of expanding and contracting under the influence of tempe­ rature fluctuations. Where the sections join one another, they form a butt joint, which must be sealed. It is a known process to do this with a plastic sealing material. In the long run, this material dries out and then loses its sealing action, with the result that leakage can occur at the site of the joint and can give rise to soiling of the wall. Moreover sealing the butt joint during the erection of the eaves section is an additional time-consuming job. The object of the invention is to produce an eaves section in which the sealing of the butt joint can be achieved quickly and simply and thereafter ensures a permanent seal. This object is achieved according to the invention in that the inward-directed horizontal leg of the top edge has a downward-­ directed edge at or near its end, and the top face of the support­ ing leg has placed on it a flat section which rests with its body on the top face of the supporting leg and covers it over part of the length of the supporting leg, with a downward-curved edge engages round the end edge of the supporting leg and engages under the horizontal leg of the top edge with a spring lip which rests against the downward-directed edge of said horizontal leg. The flat covering section is placed at the site of the joint on the top face of the supporting leg and pushed in the direction of the vertical leg until the spring lip snaps into position. The joint between the end edges of successive supporting legs of eaves sections is then completely covered, with a section which prevents any accumulation of dirt on the top face, in particular under the horizontal leg of the top edge, from penetrating into the joint. If desired, the vertical joint between the vertical legs of successive sections can be sealed with a sliding flat strip. The invention will now be explained in greater detail with reference to the drawings. Fig. 1 shows the section according to the invention in per­ spective. Fig. 2 shows the section in cross section. Fig. 1 shows two butt-jointed eaves sections 1 having a vertical leg 2 which is turned inwards at the bottom edge 3, and which at the top edge has a horizontal leg 4, while between bottom edge and top edge there is a supporting leg 5 which forms an acute angle with the vertical leg 2 and is provided with supporting ribs 6 which run parallel to the vertical leg, and between which a sealing section such as that shown at 7 can be fitted, said section being compressed when erected. The butt joint is shown at 8. Said butt joint is sealed with a flat section 9. Said section 9 is of such length that it extends over the supporting legs of successive eaves sections along a certain length on either side of the butt joint 8. It covers the full width of the supporting leg 5 and is turned over at its in­ ward-directed edge 10, so that it engages round the edge 11 of the supporting leg. At the other side it is turned over at right angles approximately twice to form a vertical leg 12 and a horizontal leg 13 which is sprung, for example by providing the constriction 14. The horizontal leg 4 has a downward-directed edge 15, behind which the spring leg 13 of the covering section can engage, for example by means of an upward-directed edge 16. After placing on the eaves, schematically indicated by 17, and fixing of the sections by known means, such as screws provided with seals at the centre line 18, the sealing of the butt joint 8 is carried out at the supporting legs by sliding the section 9 until the spring leg 13 snaps into position. If a seal is desired at the butt joint between the vertical legs 2, this can be carried out with a sliding strip 19 which is placed in a fixed section and is pushed up after erection of the next section. The circumstances are, however, different at the vertical joint, and sealing is less vital.

Claims: 1. Eaves section which, viewed in cross section, comprises a leg (2) which is in a vertical plane in the erected position 1, and which is turned inwards at the bottom edge (3) and at the top edge, which in the erected position is at a distance above the roof covering, has an inward-directed, essentially horizontal leg (4), said vertical leg (2) having between the bottom edge (3) and the top edge (4) a supporting leg (5) which forms an acute angle with the part of the vertical leg (2) lying below it and at its bottom face is provided with one or more vertical ribs (6) or similar supporting means, characterized in that the inward-directed hori­ zontal leg (4) of the top edge has a downward-directed edge (15) at or near its end, and the top face of the supporting leg (5) has placed on it a flat section (9) which rests with its body on the top face of the supporting leg (5) and covers it over part of the length of the supporting leg, with a downward-curved edge (10) engages round the end edge (11) of the supporting leg (5) and engages under the horizontal leg (4) of the top edge with a spring lip (13) which rests against the downward-directed edge (15) of said horizontal leg (4). 2. Eaves section according to Claim 1, characterized in that the spring lip (13) is formed by the top leg (12, 13) of an edge of the flat section which is turned over twice at right angles and has an upright edge (16) at its end.
