Abstract

The gutter bracket is made from a strip of factory lacquered 1-1.5mm thick steel plate. The longitudinal edges of the strip are three times folded to the centre to provide a narrower flat strip (1,2) comprising four thicknesses of plate. A tab (5) is pressed from the upper thickness of plate, and a second single thickness tab (3) projects from the end. The straight part of the bracket (1) is holed for wall or facia fixings, and the support plate (2) is bent to the gutter radius. The gutter is secured by the flexible tabs (3,5).

Description

30 505 447 2 rännkroken enligt fig l, sedd i pilarnas II-II riktning, Fig 3 visar en vy av rännkroken enligt fig 1, sedd i pilarnas III-III riktning, och Fig 4 visar en förstorad bild av det inringade partiet i fig 3. The gutter hook according to Fig. 1, seen in the direction of the arrows II-II, Fig. 3 shows a view of the gutter hook according to Fig. 1, seen in the direction of the arrows III-III, and Fig. 4 shows an enlarged view of the circled portion in Fig. 3. .

I fig l, 2 visas rännkroken närmare. Denna innefattar ett relativt långt, rakt parti 1, som övergår i ett U-forrnsliknande parti 2. Det raka partiet 1 är avsett att fästas i taket eller väggen på ett hus, medan det U-forrnsliknande partiet 2 är avsett att mottaga en hängränna och övergår i ett utsprångsliknande parti 3, vilket är avsett att vikas över ett längsgående kantparti hos hängrännan för fixering av hängrännan i rännkroken. Rännkroken uppvisar ett antal hål 4 för spikar eller skruvar att användas vid fastsättning av densamma på huset.Figures 1, 2 show the gutter hook in more detail. This comprises a relatively long, straight portion 1, which merges into a U-shaped portion 2. The straight portion 1 is intended to be attached to the roof or wall of a house, while the U-shaped portion 2 is intended to receive a gutter and merges into a projection-like portion 3, which is intended to be folded over a longitudinal edge portion of the gutter for fixing the gutter in the gutter hook. The gutter hook has a number of holes 4 for nails or screws to be used when attaching the same to the housing.

Hängrännan är normalt försedd med två längsgående kantpartier. Dess andra kantparti är avsett att hållas på plats med hjälp av ett tungliknande organ 5, som är utstansat ur plåtmaterialet och anordnat ungefär vid övergången mellan det raka partiet 1 och det U- forrnsliknande partiet 2 på rännkroken.The gutter is normally provided with two longitudinal edge portions. Its second edge portion is intended to be held in place by means of a tongue-like member 5, which is punched out of the sheet material and arranged approximately at the transition between the straight portion 1 and the U-shape-like portion 2 on the gutter hook.

Plåtrnaterialet, som hängrännan tillverkas av, utgöres företrädesvis av en fabriks- lackerad stålplåt i form av ett stålband på en rulle. Denna stålplåt är relativt tunn, endast 1- 1,5 mm. Detta innebär att ett sådant material normalt skulle ha för dålig vridstyvhet. En viktig del av uppfinningen är sålunda att stälbandet bockas en eller ﬂera gånger (se fig 3,4) på ett sådant sätt att det bockade bandet blir smalare och tjockare än det ursprungliga bandet, varigenom vridstyvheten ökar. Detta innebär att trots att utgångsmaterialet är ett tunt och sålunda billigt band, blir ändock den slutgiltiga rännkroken av bastant slag.The sheet material from which the gutter is made preferably consists of a factory-painted steel sheet in the form of a steel strip on a roll. This steel plate is relatively thin, only 1- 1.5 mm. This means that such a material would normally have too poor torsional rigidity. An important part of the invention is thus that the adjusting belt is bent once or twice (see Fig. 3.4) in such a way that the bent belt becomes narrower and thicker than the original belt, whereby the torsional rigidity increases. This means that despite the fact that the starting material is a thin and thus cheap strip, the final gutter hook will still be of a solid type.

Enligt den föredragna utföringsforrnen är bandet ungefär 100 mm brett och sker bockningen i tre steg. För att ytterligare öka vridstyvheten sker bockningen på ett sådant sätt att de inåtbockade partierna 6, 7 går emot varandra ungefär vid mitten av bandet. Bockningen av plåtrnaterialet sker över hela den blivande rännkroken utom vid det utsprångsliknande partiet 3.According to the preferred embodiment, the strip is approximately 100 mm wide and the bending takes place in three steps. To further increase the torsional rigidity, the bending takes place in such a way that the inwardly bent portions 6, 7 go against each other approximately at the middle of the belt. The bending of the sheet material takes place over the entire future gutter hook except at the protrusion-like portion 3.

Uppﬁnningen kan naturligtvis modifieras inom ramen för efterföljande patentkrav.The invention can of course be modified within the scope of the appended claims.

Sålunda kan utgångsmaterialet vara ett annat än stålplåt. Det viktiga är emellertid att det metalliska materialet föreligger i form av ett tunt, brett band, företrädesvis förlackerat och företrädesvis på rulle av godtycklig längd, vilket band avklippes i lämpliga längder, bearbetas och bockas.Thus, the starting material may be other than sheet steel. The important thing, however, is that the metallic material is in the form of a thin, wide strip, preferably lacquered and preferably on a roll of any length, which strip is cut into suitable lengths, processed and bent.

Claims

10 15 20 25 30 I sus 447 Patent claim

Method for producing a gutter hook, intended for hanging a longitudinal edge portion provided with a longitudinal edge portion, characterized by the combination of the following steps: - A relatively thin strip of suitable length and provided with two longitudinal edge portions is cut from a belt roll of a certain width; - One end portion of the band is formed as a projection (3), intended to be folded around the edge portion of the hand strap; The two longitudinal edge portions of the belt are bent inwards towards the center of the belt so that the bent belt becomes narrower and thicker than the original belt, whereby the torsional rigidity of the belt increases; The portion (2) of the bent belt, which is arranged next to the projection (3), is bent into a shape resembling a U, so that the portion can receive the gutter.

Method according to claim 1, characterized in that the bending of the edge portions of the belt is done in at least two steps, and preferably in three steps, so that the bent portions (6, 7) go against each other.

Gutter hook made according to the method according to claim 1 or 2, characterized by the combination of the following features: - It has a U-shape-like portion (2), which is intended to receive a gutter, and which at one end turns into a protrusion-like portion (3), intended to be folded over an edge of the gutter, and at the other end of a portion (1), by means of which the gutter hook can be attached to the roof or wall of a house; The fastening portion (1) and the U-shape-like portion (2) are made of starting material in the form of a metallic plate of a certain width and a certain thickness, which is bent inwards towards the middle of the belt in such a way that the bent plate is narrower and thicker than the starting material.

Gutter hook according to claim 3, characterized in that the bent portions (6, 7) of the metallic plate are arranged against each other.

Gutter hook according to claim 3 or 4, characterized in that it is made of lacquered sheet steel. P32670SE0l IÖW, YA
