Abstract

This invention relates to a method of making a gutter circle intended for hanging up a hanging gutter provided with a longitudinal edge portion. According to the invention the method is characterized by the combination of the following steps: a relatively thin band of suitable length and provided with two longitudinal edge portions is cut off from a band roll of a certain width; the one end portion of the band is designed like a projection (3), intended to be bent round the edge portion of the hanging gutter; the two longitudinal edge portions of the band are bent inwards so that the bent band becomes narrower and thicker than the original band, whereby the torsional rigidity of the band increases; that portion (2) of the bent band which is arranged close to the projection (3) is bent to a form which is like a U so that the portion can receive the hanging gutter. The invention also relates to a gutter circle made in accordance to the method.

Description

A device for a gutter and a method of manufacturing the device
This invention relates to a method of manufacturing a gutter circle, intended for hanging up a hanging gutter provided with a longitudinal edge portion. The invention also relates to a gutter circle manufactured according to the method.
Gutter circles being in the market today are oftenly manufactured of flat iron bars. After the manufacture the gutter circles are transported away for lacquering. This manufacturing procedure is complicated and time-consuming and therefore becomes expensive.
This invention intends to simplify the manufacture of gutter circles and by that to reduce the cost of the manufacture. This has been made possible by me mentioned method which is characterized by the combination of the following steps:
- A relatively thin band of suitable length and provided with two longitudinal edge portions is cut off from a band roll of a certain width;
- The one end portion of the band is designed like a projection 3, intended to be bent round the edge portion of the hanging gutter; - The two longitudinal edge portions of the band are bent inwards so that the bent band becomes narrower and thicker that the original band, whereby the torsional rigidity of the band increases;
- That portion of the bent band which is arranged close to the projection is bent to a form which is like a U so that the portion can receive the hanging gutter. By FR, Al, 2.425.515 is previously known a gutter circle wich has an irregular¬ ly corrugated design for increasing the torsional rigidity, i.e. the resistance against torsion. This means that this gutter circle requires a complicated machine for the manufac¬ ture, and therefore the manufacturing cost for this type of gutter circle becomes very high. By each of US, A, 1.020.951 and 2.654.555 is a gutter circle previously known which has a U-design in cross section.
No one of the known gutter circles has a design disclosing longitudinal edge portions in the original material, which are bent in that way that the bent material is narrower and thicker that the original material, which is a characterizing feature for the gutter circle according to the present invention. This means that this new gutter circle gets an extremely good torsional rigidity, even if the original material is a very thin plate. Moreover, this new manufacturing method for gutter circles according to this invention makes possible that a relatively thin, factory-lacquered steel plate can be used, which to a high extent reduces the cost of the manufacturing procedure. A preferred embodiment of the invention shall be described more closely with reference to the accompanying drawings, where Fig 1 shows a side view of the gutter, Fig 2 shows a view of the gutter circle according to fig 1, seen in the direction of the arrows II-II, Fig 3 shows a view of the gutter circle according to fig 1, seen in the direction of the arrows III-III, and Fig 4 shows an enlarged image of the encircled portion in fig 3.
In figs 1, 2 the gutter circle is shown more closely. This one comprises a relatively long, straight portion 1, which passes over to a portion 2 which has a form like a U. The straight portion 1 is intended to be fastened to the roof or the wall of a house, whereas the U-form-like portion 2 is intended to receive a hanging gutter and passes over to a projection-like portion 3, which is intended to be folded over a longitudinal edge portion of the hanging gutter for fixation of the hanging gutter in the gutter circle. The gutter circle has a number of holes for nails or screws to be used when fastening the same on the house. The hanging gutter is normally provided with two longitudinal edge portions. Its other edge portion is intended to be kept in place by means of a tongue-like means 5, which is punched out of the plate material and arranged substantially at the transition portion between the straight portion 1 and the U-form-like portion 2 of the gutter circle. The plate material, which the hanging gutter is manufactured of, preferably comprises a factory-lacquered steel plate in the form of a steel band on a roll. This steel plate is relatively thin, only 1-1,5 mm. This means that such a material would normally have a too poor torsional rigidity. Thus, an important part of the invention is that the steel band is bent one or several times (see fig 3, 4) in such a way that the bent band becomes narrower and thicker that the original band, whereby the torsional rigidity increases. This means that in spite of the fact that the original material is a thin and accordingly an inexpensive band, the final gutter circle yet becomes rigid.
According to the preferred embodiment the band has a width of about 100 mm and the bending is made in three steps. In order to increase the torsional rigidity further, the bending is made in such a way that the portions 6, 7, bent inwards, go against each other and touches each other approximately at the middle of the band. The bending of the plate material is made over the entire prospective gutter circle except at the projection-like portion 3. The invention can of course be modified within the scope of the following claims. Thus, the original material can be another one than steel plate. The important thing, however, is that the metallic material is in the form of a thin, broad band, preferably pre- lacquered and preferably on a roll of arbitrary length, which band is cut off in suitable lengths, worked up and bent.

Claims

Patent claims
1. A method of manufacturing a gutter circle, intended for hanging up a hanging gutter provided with a longitudinal edge portion, characterized by the com¬ bination of the following steps: - A relatively thin band of suitable length and provided with two longitudinal edge portions is cut off from a band roll of a certain width;
- The one end portion of the band is designed like a projection (3), intended to be bent round the edge portion of the hanging gutter;
- The two longitudinal edge portions of the band are bent inwards so that the bent band becomes narrower and thicker than the original band, whereby the torsional rigidity of the band increases;
- That portion (2) of the bent band which is arranged close to the projection (3) is bent to a form which is like a U, so that the portion can receive the hanging gutter.
2. A method according to claim 1, characterized in that the bending of the edge portions of the band is made in at least two steps, and preferably in three steps, so that the bent portions 6, 7 go against each other.
3. A gutter circle manufactured according to the method according to claim 1 or 2, characterized by the combination of the following features:
- It has a U-form-like portion (2), which is intended to receive a hanging gutter, and which at its one end passes over to a projection-like portion (3), intended to be bent over an edge of the hanging gutter and at its other end to a portion (1) by means of which the gutter circle can be fastened to the roof or the wall of a house;
- The fastening portion (1) and the U-form-like portion (2) are made of an original material in the form of a metallic plate of a certain width and a certain thickness, which plate is bent in such a way that the bent plate is narrower and thicker than the original material.
4. A gutter circle according to claim 3, characterized in that the bent portions (6, 7) of the metallic plate are arranged in that way that they go against each other.
5. A gutter circle according to claim 3 or 4, characterized in that it is made of a pre-lacquered steel plate.
